PRELIMINARY PROXY STATEMENT AND PRELIMINARY PROSPECTUS

SUBJECT TO COMPLETION, DATED December 29, 2021

NOVUS CAPITAL CORPORATION II

8556 Oakmont Lane
Indianapolis, IN 46260

Dear Novus Capital Corporation II Stockholders:

Novus Capital Corporation II, a Delaware corporation (“Novus”), NCCII Merger Corp., a wholly-owned subsidiary of Novus incorporated in the State of Delaware (“Merger Sub”), and Energy Vault, Inc., a Delaware corporation (“Energy Vault”), have entered into a Business Combination Agreement and Plan of Reorganization (the “Business Combination Agreement”) pursuant to which Merger Sub will merge with and into Energy Vault, with Energy Vault surviving the merger and becoming a wholly-owned direct subsidiary of Novus (collectively with the other transactions described in the Business Combination Agreement, the “Business Combination”). At the closing of the Business Combination, each of the then issued and outstanding shares of Energy Vault common stock (including each share of Energy Vault preferred stock that will be converted into shares of Energy Vault common stock immediately prior to such closing) will be cancelled and automatically convert into the right to receive the number of shares of Novus common stock equal to the exchange ratio (determined in accordance with the Business Combination Agreement and as further described herein). Based on the anticipated exchange ratio of 6.7892, Novus will issue 106,566,033 shares of Novus common stock to the stockholders of Energy Vault plus up to an additional 8,251,906 shares of Novus common stock that may be issuable pursuant to outstanding Energy Vault options and restricted stock units. The exchange ratio is equal to the quotient obtained by dividing (i) 100,000,000 by (ii) the number of shares of Energy Vault common stock outstanding on a fully diluted basis (excluding the outstanding shares of Energy Vault Series C preferred stock for purposes of calculating the exchange ratio). The 106,566,033 shares of Novus common stock have a value of approximately $1.07 billion based on a price of $10.00, the per share amount held in Novus’s Trust Account on January , 2022, the record date for the special meeting of the stockholders or $[ ] billion based on the closing sale price of the Novus common stock of $[ ] on the NYSE on January , 2022, the record date for the special meeting of stockholders. If all of the additional 8,251,906 shares Novus common stock described above are issued, such shares would have a value (after reduction for the aggregate exercise price of the Energy Vault options) of approximately $76.0 million based on a price of $10.00, the per share amount held in Novus’s Trust Account on January , 2022, the record date for the special meeting of the stockholders, or $[ ] billion based on the closing sale price of the Novus common stock of $[ ] on the NYSE on January , 2022, the record date for the special meeting of stockholders. In addition, the holders of Energy Vault common stock (including each share of Energy Vault preferred stock that will be converted into shares of Energy Vault common stock immediately prior to such closing) and holders of Energy Vault equity awards immediately prior to such closing are eligible to receive up to 9,000,000 additional shares of Novus common stock (the “Earn Out Shares”) upon the achievement of certain earn out targets.

Upon completion of the Business Combination, it is anticipated that Energy Vault’s stockholders will own approximately 68.0% of the total outstanding common stock of the combined company, assuming that none of the Public Stockholders exercise their redemption rights and that no Earn Out Shares are issued. On September 8, 2021 and in December 2021, Novus executed subscription agreements with certain investors for the sale of an aggregate of approximately 15,000,000 shares of Novus Class A common stock at a purchase price of $10.00 per share for gross aggregate proceeds of approximately $150.0 million (the “PIPE”). The closing of the sale of the PIPE will occur concurrently with the consummation of the Business Combination. See the section titled “The Business Combination” on page 112 of the attached proxy statement/prospectus for further information on the consideration being paid to the stockholders of Energy Vault. Following the Business Combination and the related financing, Novus’s stockholders will own approximately 22.4% of the outstanding common stock of the Combined Company, assuming that none of the Public Stockholders exercise their redemption rights and that no Earn Out Shares are issued and excluding shares purchased by them in the PIPE or approximately 9.6%. in the event that Novus’s public stockholders exercise their redemption rights to the maximum extent permitted under the Business Combination Agreement).

Novus’s units, common stock and warrants are currently listed on the New York Stock Exchange, or the NYSE, under the symbols “NXU.U,” “NXU,” and “NXU WS,” respectively. Novus has applied to list the shares of common stock and the warrants of Novus on the NYSE under the symbols “NRGV” and “NRGV WS,” respectively, upon the closing of the Business Combination. At the closing of the Business

Combination, each Novus unit will be separated into its components, which consists of one share of common stock and one-third of warrant, and such units will no longer exist. Upon closing, Novus intends to change its name from “Novus Capital Corporation II” to “Energy Vault Holdings, Inc.”

Novus is holding a special meeting of its stockholders in order to obtain the stockholder approvals necessary to complete the Business Combination. At the Novus special meeting of stockholders, which will be held on , 2022, at 10:00 a.m., Eastern time, via live webcast at the following address: , unless postponed or adjourned to a later date, Novus will ask its stockholders to adopt the Business Combination Agreement thereby approving the Business Combination and approve the other proposals described in this proxy statement/prospectus.

In light of the ongoing health concerns relating to the COVID-19 pandemic and to best protect the health and welfare of Novus’s stockholders and personnel, the special meeting will be held completely virtually, conducted only via webcast at the following address: . There will be no physical meeting location. Stockholders are nevertheless urged to vote their proxies by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage paid envelope.

Pursuant to Novus’s amended and restated certificate of incorporation, Novus is providing the holders of shares of Novus Class A Common Stock (the “Novus Common Stock”) originally sold as part of the units issued in our initial public offering (the “IPO” and such holders, the “Public Stockholders”) with the opportunity to redeem, upon the Closing, shares of Novus Common Stock then held by them for cash equal to their pro rata share of the aggregate amount on deposit (as of two business days prior to the Closing) in the trust account (the “Trust Account”) that holds the proceeds (including interest not previously released to Novus to pay its income taxes or any other taxes payable) from the IPO and a concurrent private placement of warrants to the initial stockholders of Novus listed on Schedule C of the Business Combination Agreement (“Novus Initial Stockholders”) and NCCII Co-Invest LLC (together with the Novus Initial Stockholders, the “Founders”). For illustrative purposes, based on the fair value of cash and marketable securities held in the Trust Account as of January , 2022, the record date of the special meeting of the stockholders (the “Record Date”) of approximately $287.5 million, the estimated per share redemption price would have been approximately $10.00. Public stockholders may elect to redeem their shares whether or not they are holders as of the record date and whether or not they vote for the Business Combination Proposal. A Public Stockholder, together with any of his, her or its affiliates or any other person with whom he, she or it is acting in concert or as a “group” (as defined in Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from seeking redemption rights with respect to more than an aggregate of 15% of the Novus Common Stock. Holders of Novus’s outstanding warrants sold in the IPO, which are exercisable for shares of Novus Common Stock under certain circumstances, do not have redemption rights in connection with the Business Combination. In connection with the IPO, the Founders agreed for no additional consideration to waive their redemption rights in connection with the consummation of the Business Combination with respect to their respective Founder’s shares (but not with respect to any shares of Novus Common Stock purchased in the PIPE or in the open market), and such Founder’s shares will be excluded from the pro rata calculation used to determine the per share redemption price. As of the Record Date the Founders, including Novus’s officers and directors, own approximately % of outstanding Novus Common Stock. The Novus Initial Stockholders, including Novus’s officers and directors, have agreed to vote any shares of Novus Common Stock owned by them in favor of the Business Combination.

Novus may not consummate the Business Combination unless the Business Combination Proposal, each of the Charter Proposals, the Equity Incentive Plan Proposal and the NYSE Proposal are approved at

TABLE OF CONTENTS

the special meeting, each of which is conditioned upon all such proposals having been approved at the special meeting. The approval of the Business Combination Proposal and the NYSE Proposal requires the affirmative vote (virtually in person or by proxy) of holders as of the Record Date of a majority of the then outstanding shares of Novus Common Stock and Novus Class B Common Stock entitled to vote thereon at the special meeting, voting together as a single class. Approval of the Charter Proposals requires the affirmative vote of the holders of a majority of the outstanding shares of the Novus Common Stock and Novus Class B Common Stock, voting together as a single class, and the affirmative vote of the holders of a majority of the Novus Class B Common Stock then outstanding, voting separately as a single class. The approval of the Equity Incentive Plan Proposal requires that the holders of a majority of the shares of Novus Common Stock and the Novus Class B Common Stock represented in person online or by proxy and voted thereon at the special meeting vote “FOR” each such proposal, voting together as a single class. The Adjournment Proposal is not conditioned on the approval of any other Stockholder Proposal set forth in the accompanying proxy statement/prospectus.

QUESTIONS AND ANSWERS ABOUT THE BUSINESS COMBINATION

The following questions and answers briefly address some commonly asked questions about the proposals to be presented at the special meeting of stockholders, including with respect to the proposed Business Combination. The following questions and answers may not include all the information that is important to Novus’s stockholders. Stockholders are urged to read carefully this entire proxy statement/prospectus, including the financial statements and annexes attached hereto and the other documents referred to herein.

Why am I receiving this proxy statement/prospectus?

Novus has entered into the Business Combination Agreement with Energy Vault and Merger Sub pursuant to which Merger Sub will be merged with and into Energy Vault, with Energy Vault surviving the Merger as a wholly-owned subsidiary of Novus. A copy of the Business Combination Agreement is attached to this proxy statement/prospectus as Annex A, and Novus encourages its stockholders to read it in its entirety. Novus’s stockholders are being asked to consider and vote upon the Business Combination Proposal to approve and adopt the Business Combination and the Business Combination Agreement, among other Stockholder Proposals. See the section titled “Proposal No. 1 — The Business Combination Proposal.”

The Novus Common Stock, Novus Warrants and Novus Units are currently listed on the NYSE under the symbols “NXU,” “NXU WS” and “NXU.U,” respectively. Novus has applied to list the shares of common stock and the warrants of the Combined Company on the NYSE under the symbols “NRGV” and “NRGV WS,” respectively, upon Closing. All outstanding Novus Units will be separated into their component securities immediately prior to the Closing. Accordingly, Novus will no longer have any units following consummation of the Business Combination, and therefore Novus will instruct the NYSE to remove the listing of the Novus Units immediately following the consummation of the Business Combination. Upon Closing, Novus intends to change its name from “Novus Capital Corporation II” to “Energy Vault Holdings, Inc.”.

This proxy statement/prospectus and its annexes contain important information about the proposed Business Combination and the proposals to be acted upon at the special meeting. You should read this proxy statement/prospectus and its annexes carefully and in their entirety. This document also constitutes a prospectus of Novus with respect to the Combined Company Common Stock issuable in connection with the Business Combination.

What matters will stockholders consider at the special meeting?

At the Novus special meeting of stockholders, Novus will ask its stockholders to vote in favor of the following Stockholder Proposals:

The Business Combination Proposal — To consider and vote upon a proposal to approve and adopt the Business Combination Agreement and the resulting Business Combination.

The Charter Proposals — To consider and vote upon amendments to Novus’s amended and restated certificate of incorporation (the “Existing Certificate of Incorporation”). The proposed amendments detailed below are collectively referred to as the “Charter Proposals.”:

•

Name Change Charter Amendment — to change Novus’s name to “Energy Vault Holdings, Inc.”;

•

Common Stock Reclassification Amendment — to eliminate the Class B Common Stock classification and provide for a single class of common stock; and

•

TABLE OF CONTENTS

•

Corporate Opportunity Charter Amendment — to eliminate the current limitations in place on the corporate opportunity doctrine;

•

The Equity Incentive Plan Proposal — To consider and vote upon the adoption of the 2022 Plan established to be effective after the Closing to assist the Combined Company in retaining the services of eligible employees, directors and consultants, to secure and retain the services of new employees, directors and consultants and to provide incentives for such persons to exert maximum efforts for the Combined Company’s success.

The NYSE Proposal — To consider and vote upon a proposal to (i) issue Combined Company Common Stock to (a) the Energy Vault Stockholders as a result of the Merger pursuant to the Business Combination Agreement; and (b) the investors in the PIPE; and (ii) issue equity awards under the 2022 Plan if such plan is approved in accordance with Proposal 3 (Equity Incentive Plan Proposal).

The approval of the Business Combination Proposal requires the affirmative vote (virtually in person or by proxy) of the holders of a majority of the then outstanding shares of Novus Common Stock and Novus Class B Common Stock entitled to vote thereon at the special meeting, voting together as a single class. Accordingly, a Novus stockholder’s failure to vote by proxy or to vote online at the virtual special meeting of stockholders, an abstention from voting or a broker non-vote will have the same effect as a vote against this Stockholder Proposal.

Approval of the Charter Proposals requires the affirmative vote of the holders of a majority of the outstanding shares of the Novus Common Stock and Novus Class B Common Stock, voting together as a single class, and the affirmative vote of the holders of a majority of the Novus Class B Common Stock then outstanding, voting separately as a single class. Accordingly, a Novus stockholder’s failure to vote by proxy or to vote online at the virtual special meeting of stockholders, an abstention from voting or a broker non-vote will have the same effect as a vote against these Stockholder Proposals.

The approval of the Equity Incentive Plan Proposal and Adjournment Proposal requires the affirmative vote (virtually in person or by proxy) of the holders of a majority of the shares of Novus Common Stock and Novus Class B Common Stock, that are voted at the special meeting of stockholders, voting together as a single class. Accordingly, a Novus stockholder’s failure to vote by proxy or to vote online at the virtual special meeting of stockholders, an abstention from voting, or a broker non-vote will have no effect on the outcome of any vote on these Stockholder Proposals.

The approval of the NYSE Proposal requires the affirmative vote (virtually in person or by proxy) of a majority of the shares of Novus Common Stock and Novus Class B Common Stock that

TABLE OF CONTENTS

are voted at the special meeting of stockholders, voting together as a single class. Pursuant to the rules of the NYSE, abstentions from voting are counted as a vote against the NYSE Proposal.

As of the Record Date, the Novus Founders beneficially owned an aggregate of 7,187,500 shares of Novus Class B Common Stock, constituting all of the outstanding shares of Novus Class B Common Stock and approximately 20.0% of the outstanding shares of Novus Common Stock and Novus Class B Common Stock in the aggregate. Pursuant to the Sponsor Support Agreement, the Novus Founders have agreed to vote all of their Initial Stockholder Shares and any Public Shares acquired by them in favor of the Business Combination and each of the Stockholder Proposals. As of the date of this proxy statement/prospectus, certain of the Founders and their affiliates have agreed to purchase an aggregate of 1,100,000 shares of Novus Common Stock in the PIPE; however, such shares will not be outstanding as of the Record Date and will not be enabled to vote in the Novus special meeting of stockholders.

Novus will hold a special meeting of its stockholders to consider and vote upon these proposals. This proxy statement/prospectus contains important information about the proposed Business Combination and the other matters to be acted upon at the special meeting. Stockholders should read it carefully.

The vote of stockholders is important. Stockholders are encouraged to vote by submitting their proxy as soon as possible after carefully reviewing this proxy statement/prospectus.

I am a Novus warrant holder. Why am I receiving this proxy statement/prospectus?

Upon consummation of the Business Combination, the Novus Warrants shall, by their terms, entitle the holders in the aggregate to purchase 9,583,333 shares of Combined Company Common Stock in lieu of 9,583,333 shares of Novus Common Stock at a purchase price of $11.50 per share. This proxy statement/prospectus includes important information about Energy Vault and the business of Energy Vault following consummation of the Business Combination. Novus and Energy Vault urge you to read the information contained in this proxy statement/prospectus carefully.

Are any of the proposals conditioned on one another?

Novus may not consummate the Business Combination unless the Business Combination Proposal, each of the Charter Proposals, the Equity Incentive Plan Proposal, and the NYSE Proposal are approved at the special meeting, each of which is conditioned upon all such proposals having been approved at the special meeting. The Adjournment Proposal is not conditioned on the approval of any other Stockholder Proposal set forth in this proxy statement/prospectus.

It is important for you to note that in the event that the Business Combination Proposal is not approved, then Novus will not consummate the Business Combination. If Novus does not consummate the Business Combination and fails to complete an initial business combination by February 8, 2023 or obtain the approval of Novus’s stockholders to extend the deadline for Novus to consummate an initial business combination, then Novus will be required to dissolve and liquidate.

What will happen upon the consummation of the Business Combination?

On the Closing Date, Energy Vault will merge into Merger Sub, whereupon Merger Sub will cease to exist and Energy Vault will continue as the surviving entity and become a direct wholly-owned subsidiary of Novus. The Merger will have the effects specified under Delaware law. At the Closing, all of the then outstanding shares of Energy Vault Common Stock will be cancelled and automatically converted into up to an aggregate of 106,566,033 shares of Combined Company Common Stock. In addition, on the Closing Date, the PIPE will be consummated, and the net proceeds will be released to the Combined Company. It is also anticipated that we will reserve for issuance up to 8,251,906 shares of Combined Company Common Stock in respect of Combined Company Options and Combined Company RSUs issued in exchange for outstanding pre-merger Energy Vault Options and Energy Vault RSUs. Additionally, during the Earn Out Period, the holders of Energy Vault Common Stock, Energy Vault Options and Energy Vault Awards outstanding

TABLE OF CONTENTS

immediately prior to the Effective Time are eligible to receive up to 9,000,000 additional shares of Combined Company Common Stock in the aggregate, referred to herein as the Earn Out Shares, in three equal tranches upon the occurrence of each Earn Out Triggering Event. For more information about the Business Combination Agreement and the Business Combination, see the section entitled “The Business Combination.”

Why is Novus proposing the Business Combination Proposal?

Novus was organized for the purpose of entering into a merger, capital stock exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities. Novus is not limited to a particular industry or geographic region.

Novus received $287.5 million from its IPO and sale of the Private Warrants, which was placed into the Trust Account immediately following the IPO. In accordance with the Existing Certificate of Incorporation, holders of Public Shares may redeem such shares for cash equal to their pro rata share of the aggregate amount on deposit in the Trust Account upon the consummation of the Business Combination. See the question titled “What happens to the funds held in the Trust Account upon consummation of the Business Combination?” for more information.

There are currently 28,750,000 shares of Novus Common Stock and 7,187,500 shares of Novus Class B Common Stock issued and outstanding. In addition, there are currently 14,749,999 Novus Warrants issued and outstanding, consisting of 9,583,333 Public Warrants and 5,166,666 Private Warrants. Each whole Novus Warrant entitles the holder thereof to purchase one share of Novus Stock at a price of $11.50 per share. The Novus Warrants will become exercisable 30 days after the completion of a business combination, and expire at 5:00 p.m., New York City time, five years after the completion of a business combination or earlier upon redemption or liquidation.

Under the Existing Certificate of Incorporation, all holders of Public Shares have the opportunity to have their Public Shares redeemed upon the consummation of a business combination. The Private Warrants are non-redeemable so long as they are held by their initial purchasers or their permitted transferees.

Did Novus’s board of directors obtain a third-party valuation or fairness opinion in determining whether or not to proceed with the Business Combination?

In connection with its determination to recommend the Business Combination, a special committee of the Novus board of directors obtained an opinion from Cassel Salpeter as to the fairness from a financial point of view to Novus, as of the date of such opinion, of the aggregate closing consideration to be issued by Novus in the Business Combination, which opinion was based on and subject to the assumptions made, procedures followed, matters considered and limitations and qualifications set forth in such opinion as more fully described above under the caption “Proposal No. 1 — The Business Combination Proposal — Opinion of Financial Advisor to the Novus Special Committee.”

Do I have redemption rights?

If you are a holder of Public Shares, you may redeem your Public Shares for cash equal to their pro rata share of the aggregate amount on deposit in the Trust Account, which holds the proceeds of the IPO and a concurrent private placement of warrants to the Founders, as of two business days prior to the consummation of the Business Combination, including interest earned on the funds held in the Trust Account and not previously released to Novus to pay its income taxes or any other taxes payable, upon the consummation of the Business Combination. The per share amount Novus will distribute to holders who properly redeem their shares will not be reduced by the deferred underwriting commissions Novus will pay to the underwriters of its IPO if the Business Combination is consummated. Holders of the outstanding Public Warrants do not have redemption rights with respect to such warrants in connection with the Business Combination. Notwithstanding the foregoing, a holder of Novus Common Stock, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group” (as

TABLE OF CONTENTS

defined in Section 13(d)(3) of the Exchange Act), will be restricted from seeking redemption with respect to more than 15% of the Novus Common Stock. Accordingly, no shares of Novus Common Stock in excess of 15% held by a public stockholder, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group,” will be redeemed.

In connection with the IPO, all of the Founders agreed for no additional consideration to waive their redemption rights with respect to their Founder Shares and any Public Shares that they may have acquired during or after the IPO in connection with the completion of Novus’s business combination. The Founder Shares will be excluded from the pro rata calculation used to determine the per share redemption price. For illustrative purposes, based on funds in the Trust Account of approximately $287.5 million on the Record Date, the estimated per share redemption price would have been approximately $10.00 Additionally, Public Shares properly tendered for redemption will only be redeemed if the Business Combination is consummated; otherwise, holders of such shares will only be entitled to a pro rata portion of the Trust Account, including interest (which interest shall be net of taxes payable by Novus), in connection with the liquidation of the Trust Account.

Will my vote affect my ability to exercise redemption rights?

No. You may exercise your redemption rights whether you vote your Public Shares for or against the Business Combination Proposal and other Stockholder Proposals or do not vote your shares. As a result, the Business Combination Proposal can be approved by stockholders who will redeem their Public Shares and no longer remain stockholders, leaving stockholders who choose not to redeem their Public Shares holding shares in a company with a less liquid trading market, fewer stockholders, less cash and the potential inability to meet the listing standards of the NYSE.

How do I exercise my redemption rights?

In order to exercise your redemption rights, you must, prior to 4:30 p.m. Eastern time on , 2022 (two business days before the special meeting of stockholders), (i) submit a written request to Novus’s transfer agent that Novus redeem your Public Shares for cash, and (ii) deliver your stock to Novus’s transfer agent physically or electronically through The Depository Trust Company (“DTC”). For the address of Continental Stock Transfer & Trust Company, Novus’s transfer agent, see the question “Who can help answer my questions?” below. Novus requests that any requests for redemption include the identity as to the beneficial owner making such request. Electronic delivery of your shares generally will be faster than delivery of physical stock certificates.

A physical stock certificate will not be needed if your stock is delivered to Novus’s transfer agent electronically. In order to obtain a physical stock certificate, a stockholder’s broker and/or clearing broker, DTC and Novus’s transfer agent will need to act to facilitate the request. It is Novus’s understanding that stockholders should generally allot at least two weeks to obtain physical certificates from the transfer agent. However, because Novus does not have any control over this process or over the brokers or DTC, it may take significantly longer than two weeks to obtain a physical stock certificate. Under Novus’s bylaws, Novus is required to provide at least 10 days advance notice of any stockholder meeting, which would be the minimum amount of time a stockholder would have to determine whether to exercise redemption rights. Accordingly, if it takes longer than anticipated for stockholders to deliver their shares, stockholders who wish to redeem may be unable to meet the deadline for exercising their redemption rights and thus may be unable to redeem their shares. In the event that a stockholder fails to comply with the various procedures that must be complied with in order to validly tender or redeem Public Shares, its shares may not be redeemed.

Any demand for redemption, once made, may be withdrawn at any time until the deadline for exercising redemption requests and thereafter, with Novus’s consent, until the vote is taken with respect to the Business Combination. If you delivered your shares for redemption to Novus’s transfer agent and decide within the required timeframe not to exercise your redemption rights, you may request that Novus’s transfer agent return the shares (physically or electronically). You may make

TABLE OF CONTENTS

such request by contacting Novus’s transfer agent at the phone number or address listed under the question, “Who can help answer my questions?”.

Do I have appraisal rights if I object to the proposed Business Combination?

No. There are no appraisal rights available to holders of shares of Novus Common Stock or Novus Class B Common Stock in connection with the Business Combination.

What happens to the funds held in the Trust Account upon consummation of the Business Combination?

If the Business Combination is consummated, the funds held in the Trust Account will be released to pay (i) Novus’s stockholders who properly exercise their redemption rights and (ii) expenses incurred by Energy Vault and Novus in connection with the Business Combination, to the extent not otherwise paid prior to the Closing. The remaining funds available for release from the Trust Account will be used for general corporate purposes of the Combined Company following the Business Combination.

Will Novus obtain new financing in connection with the Business Combination?

Investors have committed to purchase an aggregate of approximately 15,000,000 shares of Novus Common Stock in the PIPE at a purchase price of $10.00 per share, for an aggregate purchase price of approximately $150.0 million. In connection with the PIPE, certain of the Founders and their affiliates agreed to purchase an aggregate of 1,100,000 shares of Novus Common Stock.

What happens to the proceeds from the PIPE upon consummation of the Business Combination?

The PIPE is expected to close concurrently with the closing of the Business Combination. Upon the closing of both the Business Combination and the PIPE, the proceeds from the PIPE will be released to Novus and is expected to be used for general corporate purposes of the Combined Company.

What happens if a substantial number of public stockholders vote in favor of the Business Combination Proposal and exercise their redemption rights?

Public Stockholders may vote in favor of the Business Combination and still exercise their redemption rights. Accordingly, the Business Combination may be consummated even though the funds available from the Trust Account and the number of Public Stockholders are reduced as a result of redemptions by Public Stockholders.

In no event will Novus redeem Public Shares in an amount that would cause its net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Exchange Act) to be less than $5,000,001 after giving effect to the exercise of redemption rights. If enough Public Stockholders exercise their redemption rights such that Novus cannot satisfy the net tangible asset requirement, Novus would not proceed with the redemption of our Public Shares or the Business Combination, and instead may search for an alternate business combination.

As a result of redemptions, the trading market for the Combined Company’s common stock may be less liquid than the market for Novus Common Stock was prior to the Business Combination and the Combined Company may not be able to meet the listing standards of the NYSE or any other national securities exchange.

Additionally, with fewer funds available from the trust account, the capital infusion from the Trust Account into the Combined Company will be reduced and it may not be able to achieve its business plan and may require additional financing sooner than currently anticipated.

What happens if the Business Combination is not consummated?

There are certain circumstances under which the Business Combination Agreement may be terminated. See the section titled “The Business Combination Agreement — Termination” for information regarding the parties’ specific termination rights.

TABLE OF CONTENTS

If Novus does not complete the business combination with Energy Vault for whatever reason, Novus would search for another target business with which to complete a business combination. If Novus does not complete a business combination with Energy Vault or another target business by February 8, 2023, Novus must redeem 100% of the outstanding Public Shares, at a per share price, payable in cash, equal to the amount then held in the Trust Account divided by the number of then outstanding Public Shares. The Founders have no redemption rights in the event a business combination is not consummated in the required time period, and, accordingly, their Founder Shares will be worthless. Additionally, in the event of such a liquidation, as described above, there will be no distribution with respect to outstanding Novus Warrants and, accordingly, the Novus Warrants will expire and be worthless.

For more information, see the section titled “Information About Energy Vault.”

What factors did Novus’s Board of Directors consider in determining to enter into the Business Combination Agreement?

In approving the Business Combination, the Novus board of directors considered a number of factors pertaining to the Business Combination as generally supporting its decision to enter into the Business Combination Agreement and the transactions contemplated therein, including, but not limited to, the following:

•

Energy Vault’s innovative and disruptive business model;

•

Energy Vault’s significant market opportunity;

•

Momentum for environmentally sustainable solution and demand for investments in this area;

•

Energy Vault’s significant growth potential;

•

Novus’s due diligence of Energy Vault;

•

Energy Vault’s financial condition (see “— Certain Energy Vault Projected Financial Information”);

•

Energy Vault’s strong strategic partners and institutional investors;

•

Other alternative targets; and

•

The negotiated terms of the Business Combination.

•

The Novus board of directors also considered a variety of uncertainties and risk and other potentially negative factors concerning the Business Combination including, but not limited to, the following:

•

Energy Vault is an early-stage pre-commercialization company;

•

Macro-economic uncertainty and the effects it could have on the Combined Company’s operating results;

•

The risk of redemption by Novus’s stockholders;

TABLE OF CONTENTS

•

The risk that Novus’s stockholders may fail to provide the respective votes necessary to effect the Business Combination;

•

Closing conditions that are not within Novus’s control.

•

The possibility of litigation challenging the Business Combination

•

The risks that the potential benefits of the Business Combination may not be achieved;

•

The fact that Novus’s stockholders will hold a minority position in the Combined Company;

•

Potential conflicts of interest of Novus’s Directors and Officers (see “— Interests of Novus’s Directors and Officers in the Business Combination”); and

•

Various other risks associated with the business of Energy Vault, as described in the section titled “Risk Factors” appearing elsewhere in this proxy statement/prospectus.

The Novus board of directors also considered the Business Combination in light of the investment criteria set forth in Novus’s final prospectus for its IPO including, without limitation, that based upon Novus’s analyses and due diligence, Energy Vault has the potential to be a market leader and has substantial future growth opportunities, all of which the Novus board of directors believes have a strong potential to create meaningful stockholder value following the consummation of the Business Combination.

The above discussion of the material factors considered by the Novus board of directors is not intended to be exhaustive but does set forth the principal factors considered by the Novus board of directors. For more information, see the section titled “The Background of the Business Combination — Novus’s Board of Directors’ Reasons for the Approval of the Business Combination.”

What factors did Energy Vault’s Board of Directors consider in determining to enter into the Business Combination Agreement?

In approving the Business Combination, the Energy Vault board of directors considered a number of factors pertaining to the Business Combination as generally supporting its decision to enter into the Business Combination Agreement and the transactions contemplated therein, including, but not limited to, increased access to the capital markets, increased liquidity for its stockholders and other equityholders and other benefits of being a public reporting company. The Energy Vault board of directors also considered a variety of uncertainties and risk and other potentially negative factors concerning the Business Combination, including the costs to the Combined Company that will be incurred as a public reporting company.

What equity stake will current Novus’s stockholders and Energy Vault’s stockholders have in the Combined Company after the Closing?

The equity stake of the Novus’s Public Stockholders will depend on the number of shares of Novus Common Stock which are redeemed in connection with the Business Combination. Novus’s Public Stockholders may vote in favor of the Business Combination Proposal and still exercise their redemption rights, although they are not required to vote either for or against the Business Combination, or vote at all, or to be holders on the Record Date, in order to exercise such redemption rights. Accordingly, the Business Combination may be consummated even though the funds available from the trust account and the number of public stockholders are substantially reduced as a result of redemption by public stockholders, subject to the requirements that (i) Novus has a minimum of $170,000,000 of cash on hand after consummation of the PIPE and after distribution of the Trust Fund (for the avoidance of doubt, such cash shall be determined prior to the payment of any transaction fees, costs and expenses paid or required to be paid by Novus prior to Closing and the payment of such fees, costs and expenses shall be paid or payable out of such cash on hand)and (ii) the Combined Company have at least $5,000,001 of net tangible assets immediately prior to or upon the consummation of the Business Combination.

A Novus Public Stockholder may exercise its redemption rights, which will not result in the loss of any Warrants that the Novus Public Stockholder may hold. Accordingly, even if the maximum

TABLE OF CONTENTS

number of shares was redeemed, there would still be 9,583,333 Public Warrants and 5,166,666 Private Warrants outstanding. Further, if the Combined Company Common Stock is trading above the exercise price of $11.50 per warrant, the warrants are considered to be “in the money” and are therefore more likely to be exercised by the holders thereof (when they become exercisable). This in turn increases the risk to non-redeeming stockholders that the warrants will be exercised, which would result in immediate dilution to the non-redeeming stockholders. As of the Record Date, the closing price of the warrants was $ per warrant.

The potential impact of different redemption levels is illustrated below through a comparison of a no redemption, illustrative redemption, contractual maximum redemption and minimum cash condition waiver scenarios (as described below). In the sensitivity table below, the residual equity value owned by non-redeeming stockholders, taking into account the respective redemption amounts, is assumed to remain the deemed value of $10.00 per share. As a result of such redemption amounts and the assumed $10.00 per share value, the implied total equity value of the Combined Company, assuming no dilution from any of the Public Warrants, Private Warrants, Energy Vault Options, Energy Vault RSUs or the Earn Out Shares (“Additional Dilution Sources”), would be (a) $1,541,817,880 in the no redemption scenario, (b) $1,384,708,510 in the illustrative redemption scenario, and (c) $1,301,679,700, in the contractual maximum redemption scenario. Additionally, the sensitivity table below sets forth the potential additional dilutive impact of each of the Additional Dilution Sources in each redemption scenario. Increasing levels of redemption will increase the dilutive effects of these issuances on non-redeeming stockholders.

TABLE OF CONTENTS

(1)

This scenario assumes that no additional shares of Novus Common Stock are redeemed by the Public Stockholders and the Founders forfeit an aggregate of 718,750 Founder Shares.

(2)

This scenario assumes that approximately 14,375,000 shares of Novus Common Stock are redeemed by the Public Stockholders and the Founders forfeit an aggregate of 718,750 Founder Shares.

(3)

This scenario assumes that approximately 26,838,263 shares of Novus Common Stock are redeemed by the public stockholders, which, based on the amount of $287,509,721 in the trust account as of September 30, 2021, represents the maximum amount of redemptions that would still enable Novus to have sufficient cash to satisfy the minimum cash condition in the Business Combination Agreement.

(4)

This row includes all shares of Novus Common Stock which vest upon satisfaction of price targets in the number of shares held by the Founders.

(5)

This row excludes an aggregate of 8,251,906 Energy Vault Options and Energy Vault RSUs and 9,000,000 Earn Out Shares.

(6)

All share numbers and percentages for the Additional Dilution Sources are presented without the potential reduction of any amounts paid by the holders of the given Additional Dilution Sources and therefore may overstate dilution.

(7)

The Percentage of Total with respect to each Additional Dilution Source, including the Total Additional Dilutive Sources, includes the full amount of shares issued with respect to the applicable Additional Dilution Source (but not the other Applicable Dilution Sources) in both the numerator and denominator. For example, in the no redemption scenario, the Percentage of Total with respect to the Earn Out Shares would be calculated as follows: (a) 9,000,000 shares; divided by (b) (i) 156,784,788 shares (the number of shares outstanding prior to any issuance of Earn Out Shares plus (ii) 9,000,000 Earn Out Shares.

(8)

This row assumes all 9,000,000 Earn Out Shares are issued to Energy Vault securityholders.

(9)

This row assumes exercise of all Energy Vault Stock Options on a cash basis and all Energy Vault RSUs are earned and settled in shares of Combined Company Common Stock.

(10)

This row assumes exercise of all Public Warrants for cash.

(11)

This row assumes exercise of all Private Warrants for cash.

(12)

This row assumes the issuance of all shares of Combined Company Common Stock in connection with each of the Additional Dilution Sources, as described in Notes 8 through 11 above.

Who will be the officers and directors of the Combined Company if the Business Combination is consummated?

Upon the consummation of the Business Combination, the board of directors of the Combined Company (the “Combined Company Board”) will be comprised of Robert Piconi, Henry Elkus, Larry Paulson, Zia Huque, Bill Gross, Thomas Ertel and Mary Beth Mandanas divided into three separate classes, as follows:

•

the Class I directors will be Larry Paulson and Mary Beth Mandanas and their terms will expire at the first annual meeting to be held after the consummation of the Business Combination;

•

the Class II directors will be Zia Huque, Henry Elkus, and Thomas Ertel and their terms will expire at the second annual meeting to be held after the consummation of the Business Combination; and

•

the Class III directors will be Robert Piconi and Bill Gross and their terms will expire at the third annual meeting to be held after the consummation of the Business Combination.

Such directors will be appointed, effective as of the consummation of the Business Combination, by the Novus Board in accordance with Novus’s organizational documents.

Immediately following the consummation of the Business Combination, we expect that the following will be the officers of the Combined Company: Robert Piconi, Chief Executive Officer,

TABLE OF CONTENTS

Andrea Wuttke, Chief Financial Officer and Andrea Pedretti, Chief Technology Officer. See the section titled “Management After the Business Combination” for information about such officers and the Combined Company’s other executive officers.

What conditions must be satisfied to complete the Business Combination?

There are a number of closing conditions in the Business Combination Agreement, including that Novus’s stockholders have approved and adopted the Business Combination Agreement. For a summary of the conditions that must be satisfied or waived prior to completion of the Business Combination, see the section titled “The Business Combination Agreement — Conditions to Closing.”

What happens if I sell my shares of Novus Common Stock before the special meeting of stockholders?

The Record Date for the special meeting of stockholders will be earlier than the date that the Business Combination is expected to be completed. If you transfer your shares of Novus Common Stock after the Record Date, but before the special meeting of stockholders, unless the transferee obtains from you a proxy to vote those shares, you will retain your right to vote at the special meeting of stockholders.

However, you will not become a Combined Company Stockholder following the Closing because only Novus’s stockholders on the date of the Closing will become Combined Company Stockholders.

May Novus or Novus’s directors, officers or advisors, or their affiliates, purchase shares in connection with the Business Combination?

In connection with the stockholder vote to approve the proposed Business Combination, the Founders and Novus’s board of directors, officers, advisors or their affiliates may privately negotiate transactions to purchase shares prior to the Closing from stockholders who would have otherwise elected to have their shares redeemed in conjunction with a proxy solicitation pursuant to the proxy rules for a per share pro rata portion of the Trust Account without the prior written consent of Energy Vault. None of the Founders, directors, officers or advisors, or their respective affiliates, will make any such purchases when they are in possession of any material non-public information not disclosed to the seller of such shares. Such a purchase would include a contractual acknowledgement that such stockholder, although still the record holder of such shares, is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights. In the event that the Founders, directors, officers or advisors, or their affiliates, purchase shares in privately negotiated transactions from Public Stockholders who have already elected to exercise their redemption rights, such selling stockholders would be required to revoke their prior elections to redeem their shares. Any such privately negotiated purchases may be effected at purchase prices that are in excess of the per share pro rata portion of the Trust Account. The purpose of these purchases would be to increase the amount of cash available to Novus for use in the Business Combination.

In addition, certain of the officers and directors and their affiliates have agreed to purchase an aggregate of 1,100,000 shares of Novus Common Stock in the PIPE. These shares to be purchased in the PIPE will not be outstanding on the Record Date and will not be entitled to vote at the Novus special meeting of stockholders.

How many votes do I have at the special meeting of stockholders?

Novus’s stockholders are entitled to one vote at the special meeting for each share of Novus Common Stock and Novus Class B Common Stock held of record as of the Record Date. As of the close of business on the Record Date, there were 28,750,000 shares of Novus Class A common stock, par value $0.0001 per share, held by [•] holders of record, including holders of record of Novus Units, and 7,187,500 shares of Novus Class B common stock, par value $0.0001 per share, held by Common Stock holders of record.

What interests do Novus’s current officers and directors have in the Business Combination?

TABLE OF CONTENTS

Novus’s board of directors and executive officers may have interests in the Business Combination that are different from, in addition to, or in conflict with, yours. These interests include:

•

the beneficial ownership of Novus’s board of directors and officers of an aggregate of 4,869,662 shares of Novus Class B Common Stock and 2,900,625 Novus Warrants, which shares and warrants would become worthless if Novus does not complete a business combination within the applicable time period, as our directors and officers have waived any right to redemption with respect to these shares. Such shares and warrants have an aggregate market value of approximately $[*] million based on the closing prices of Novus Common Stock and warrants of $[*] and $[*], respectively on the NYSE on January [*], 2022, the Record Date for the special meeting of stockholders. Based on such market values, Novus’s board of directors and officers will have an unrealized gain of approximately $[*] million on their Novus securities;

•

our officers and directors and their affiliates have agreed to purchase an aggregate of 1,100,000 shares of Novus Common Stock in the PIPE at a purchase price of $10.00 per share, such purchase is contingent upon the completion of the Business Combination;

•

the fact that our founders, officers and directors have agreed not to redeem any of the shares of our common stock held by them in connection with a stockholder vote to approve the Business Combination;

•

Messrs. Robert J. Laikin, Chief Executive Officer, a director and a principal stockholder of Novus, Larry Paulson, Chairman of the Board and a principal stockholder of Novus, and Jeffrey Foster, a director of Novus, each purchased a non-controlling membership interest in Helena SPV for $250,000. Each such membership interest will equate to an indirect interest of 119,632 shares of Combined Company Common Stock, assuming no Earn Out Shares are issued. Each membership interest will have a value of $1,196,320 and each such director will have an unrealized gain on each director’s $250,000 investment of $946,320 (valued at $10.00 per share of Combined Company Common Stock, the per share transaction value). Based on the closing sale price of Novus Common Stock on the Record Date, each such individual’s membership interest has a value of $ [ ] and will have an unrealized gain on this investment of $[•] (based on the closing sale price of the Novus Common Stock of $[ ] as of the Record Date).

•

Novus’s board of directors will not receive reimbursement for any out-of-pocket expenses incurred by them on Novus’s behalf incident to identifying, investigating and consummating the Business Combination, to the extent such expenses exceed the amount not required to be retained in the Trust Account, unless the Business Combination is consummated;

•

the anticipated continuation of Larry Paulson, as a director of the Combined Company following the Closing;

•

the fact that the Founders who purchased Founder Shares and Private Warrants prior to or at the time of our IPO may experience a positive rate of return on their investment, even if the Public Stockholders experience a negative rate of return on their investment;

•

If Novus is unable to complete a business combination within the required time period, an affiliate of one of the Founders will be personally liable under certain circumstances described herein to ensure that the proceeds in the trust account are not reduced by the claims of target businesses or claims of vendors or other entities that are owed money by Novus for services rendered or contracted for or products sold to Novus. If Novus consummates a business combination, on the other hand, Novus will be liable for all such claims; and

•

the continued indemnification of the current directors and officers of Novus following the Business Combination and the continuation of directors’ and officers’ liability insurance following the Business Combination.

Record Date. For these reasons, our board of directors and officers and their affiliates will receive a benefit from the completion of the Business Combination. These interests may incentivize our directors and officers to complete a business combination of a less favorable target company or on terms less favorable to stockholders rather than liquidate and to vote in favor of approval of the Stockholder Proposals.

These interests may influence Novus’s board of directors in making their recommendation that you vote in favor of the approval of the Stockholder Proposals. You should also read the section titled “The Business Combination — Interests of Novus’s Directors and Officers in the Business Combination.”

What interests do the Founders and their affiliates have at risk if the Business Combination is not completed?

Our Founders (including our directors and officers) and their affiliates have the following interests in Novus and/or the Business Combination which may become worthless or not received if the Business Combination is not completed:

•

Our Founders (including our officers and directors) and their affiliates, beneficially own 7,187,500 shares of Class B Common Stock and 5,166,666 Novus Warrants, which shares and warrants would become worthless if Novus does not complete a business combination within the applicable time period, as our Founders (including our directors and officers) and their affiliates have waived any right to redemption with respect to these shares. Such shares and warrants have an aggregate market value of approximately $[*] million based on the closing prices of Novus Common Stock and warrants of $[*] and $[*], respectively on the NYSE on January [*], 2022, the Record Date.

•

Messrs. Robert J. Laikin, Chief Executive Officer, a director and a principal stockholder of Novus, Larry Paulson, Chairman of the Board and a principal stockholder of Novus, and Jeffrey Foster, a director of Novus, each purchased a non-controlling membership interest in Helena SPV for $250,000. Each such membership interest will equate to an indirect interest of 119,632 shares of Combined Company Common Stock, assuming no Earn Out Shares are issued. Based on the closing sale price of the Novus Common Stock on the Record Date, each such individual’s membership interest have a value of $[ ] and will have an unrealized gain on this investment of $[ ] (based on the closing sale price of the Novus Common Stock of $[ ] as of the Record Date).

•

Cowen, an affiliate of a Founder, will receive (i) a $10,062,500 business combination fee pursuant to the business combination marketing agreement entered into in connection with the IPO and a financial advisory fee of $7.5 million for serving as Novus’s financial advisor in connection with the Business Combination, which fees are payable upon completion of the Business Combination and (ii) a placement fee of $2.5 million for acting as a placement agent in connection with the PIPE. In the event the Business Combination is not consummated, Cowen would not receive these fee (except for the business combination fee if we were to consummate another business combination).

Accordingly, our Founders (including our directors and officers) and their affiliates) will hold securities of Novus (directly or indirectly and excluding shares of Novus Common Stock which Founders agreed to purchase in the PIPE) and receive cash fees with an aggregate value of $[ ] based on the closing prices of Novus Common Stock and warrants of $[*] and $[*], respectively on the NYSE on the Record Date. None of our Founders have any loans to us that are outstanding and any reimbursable expenses of our Founders will be paid from our available cash prior to the consummation of the Business Combination and will not be dependent upon the consummation of the Business Combination.

For these reasons, our Founders (including our directors and officers) and their affiliates will receive a benefit from the completion of the Business Combination. These interests may incentivize our Founders (including our directors and officers) to complete a business combination of a less

What are the U.S. federal income tax consequences of exercising my redemption rights?

The U.S. federal income tax consequences of a redemption depend on a holder’s particular facts and circumstances. See the section titled “Certain U.S. Federal Income Tax Considerations of the Redemption and the Business Combination.” We urge you to consult your tax advisors regarding the tax consequences of exercising your redemption rights and to rely solely upon their advice.

If I hold Novus Warrants, can I exercise redemption rights with respect to my warrants?

No. Holders of Novus Warrants have no redemption rights with respect to the Novus Warrants.

When is the Business Combination expected to be completed?

It is currently anticipated that the Business Combination will be consummated promptly following the special meeting of stockholders, provided that all other conditions to the consummation of the Business Combination have been satisfied or waived. For a description of the conditions to the completion of the Business Combination, see the section titled “The Business Combination Agreement — Conditions to Closing.”

What do I need to do now?

You are urged to carefully read and consider the information contained in this proxy statement/prospectus, including the financial statements and annexes attached hereto, and to consider how the Business Combination will affect you as a stockholder. You should then vote as soon as possible in accordance with the instructions provided in this proxy statement/prospectus on the enclosed proxy card or, if you hold your shares through a brokerage firm, bank or other nominee, on the voting instruction form provided by the broker, bank or nominee.

How do I vote?

If you were a holder of record of Novus Common Stock and/or Novus Class B Common Stock on the Record Date, you may vote on the Stockholder Proposals online at the virtual special meeting of stockholders or by completing, signing, dating and returning the enclosed proxy card in the postage-paid envelope provided. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank or other nominee, you should contact your broker, bank or nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the record holder of your shares with instructions on how to vote your shares or, if you wish to virtually attend the special meeting of stockholders and vote online, obtain a proxy from your broker, bank or nominee.

What will happen if I abstain from voting or fail to vote at the special meeting?

At the special meeting of stockholders, Novus will count a properly executed proxy marked “ABSTAIN” with respect to a particular proposal as present for purposes of determining whether a quorum is present. For purposes of approval, an abstention or failure to vote will have the same effect as a vote against each of the Business Combination Proposal, the individual Charter Proposals, and the NYSE Proposal, and will have no effect on any of the other Stockholder Proposals.

What will happen if I sign and return my proxy card without indicating how I wish to vote?

Signed and dated proxies received by Novus without an indication of how the stockholder intends to vote on a proposal will be voted in favor of each of the Stockholder Proposals.

TABLE OF CONTENTS

Do I need to attend the special meeting of stockholders to vote my shares?

No. You are invited to virtually attend the special meeting to vote on the proposals described in this proxy statement/prospectus. However, you do not need to attend the special meeting of stockholders to vote your shares. Instead, you may submit your proxy by signing, dating and returning the applicable enclosed proxy card(s) in the pre-addressed postage-paid envelope. Your vote is important. Novus encourages you to vote as soon as possible after carefully reading this proxy statement/prospectus.

If I am not going to attend the special meeting of stockholders in person, should I return my proxy card instead?

Yes. After carefully reading and considering the information contained in this proxy statement/prospectus, please submit your proxy, as applicable, by completing, signing, dating and returning the enclosed proxy card in the postage-paid envelope provided.

If my shares are held in “street name,” will my broker, bank or nominee automatically vote my shares for me?

Because none of the proposals to be voted on at the Special Meeting is a routine matter for which brokers may have discretionary authority to vote without instructions from the beneficial owner of the shares, Novus does not expect any broker non-votes at the Special Meeting. As a result, failure to provide instructions to your bank, brokerage firm or other nominee on how to vote will result in your shares not being counted as present in determining the presence of a quorum. No. If your broker holds your shares in its name and you do not give the broker voting instructions, under the applicable stock exchange rules, your broker may not vote your shares on any of the Stockholder Proposals. If you do not give your broker voting instructions and the broker does not vote your shares, this is referred to as a “broker non-vote.” Broker non-votes will be counted for purposes of determining the presence of a quorum at the special meeting of stockholders. Your bank, broker, or other nominee can vote your shares only if you provide instructions on how to vote. You should instruct your broker to vote your shares in accordance with directions you provide. However, in no event will a broker non-vote have the effect of exercising your redemption rights for a pro rata portion of the Trust Account, and therefore no shares as to which a broker non-vote occurs will be redeemed in connection with the proposed Business Combination.

May I change my vote after I have mailed my signed proxy card?

Yes. You may change your vote by sending a later-dated, signed proxy card to Novus’s secretary at the address listed below prior to the vote at the special meeting of stockholders, or attend the virtual special meeting and vote online. You also may revoke your proxy by sending a notice of revocation to Novus’s secretary, provided such revocation is received prior to the vote at the special meeting. If your shares are held in street name by a broker or other nominee, you must contact the broker or nominee to change your vote.

What happens if I fail to take any action with respect to the special meeting?

If you fail to take any action with respect to the special meeting and the Business Combination is approved by stockholders and consummated, you will become a stockholder of the Combined Company and/or your warrants will entitle you to purchase common stock of the Combined Company. As a corollary, failure to vote either for or against the Business Combination proposal means you will not have any redemption rights in connection with the Business Combination to exchange your shares of common stock for a pro rata share of the aggregate amount of funds held in the Trust Account as of two business days prior to the Closing, including any interest thereon but net of any income or other taxes payable. If you fail to take any action with respect to the special meeting and the Business Combination is not approved, you will continue to be a stockholder and/or warrant holder of Novus.

What should I do if I receive more than one set of voting materials?

You may receive more than one set of voting materials, including multiple copies of this proxy

TABLE OF CONTENTS

statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a holder of record and your shares are registered in more than one name, you will receive more than one proxy card. Please complete, sign, date and return each proxy card and voting instruction card that you receive in order to cast your vote with respect to all of your shares.

What is the quorum requirement for the special meeting of stockholders?

A quorum of Novus’s stockholders is necessary to hold a valid meeting. A quorum will be present at the special meeting of stockholders if a majority of the aggregate shares of Novus Common Stock and Novus Class B Common Stock outstanding, and entitled to vote at the meeting is virtually represented in person or by proxy, and, with respect to the separate vote by other Novus Class B Common Stock for other Charter Proposals if a majority of the shares of Novus Class B Common Stock outstanding and entitled to vote at the meeting is virtually represented in person or by proxy. Abstentions will count as present for the purposes of establishing a quorum.

As of the Record Date for the special meeting, 17,968,751 shares of Novus Common Stock and Novus Class B Common Stock will be required to achieve a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or your broker, bank or other nominee submits one on your behalf) or if you vote online at the virtual special meeting of stockholders. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, a majority of the shares represented by stockholders virtually present at the special meeting or by proxy may authorize adjournment of the special meeting to another date.

What happens to the Novus Warrants I hold if I vote my shares of Novus Common Stock against approval of the Business Combination Proposal and validly exercise my redemption rights?

Properly exercising your redemption rights as a Novus stockholder does not result in either a vote “FOR” or “AGAINST” the Business Combination Proposal. If the Business Combination is not completed, you will continue to hold your Novus Warrants, and if Novus does not otherwise consummate an initial business combination by February 8, 2023 or obtain the approval of Novus’s Stockholders to extend the deadline for Novus to consummate an initial business combination, Novus will be required to dissolve and liquidate, and your Novus Warrants will expire worthless.

Who will solicit and pay the cost of soliciting proxies?

Novus will pay the cost of soliciting proxies for the special meeting of stockholders. Novus has engaged Morrow Sodali LLC to assist in the solicitation of proxies for the special meeting. Novus has agreed to pay Morrow Sodali LLC a fee of $35,000. Novus will reimburse Morrow Sodali LLC for reasonable out-of-pocket expenses and will indemnify Morrow Sodali LLC and its affiliates against certain claims, liabilities, losses, damages and expenses. Novus also will reimburse banks, brokers and other custodians, nominees and fiduciaries representing beneficial owners of shares of Novus Common Stock for their expenses in forwarding soliciting materials to beneficial owners of Novus Common Stock and in obtaining voting instructions from such beneficial owners. Novus’s directors, officers and employees may also solicit proxies by telephone, by facsimile, by mail, on the Internet or in person. They will not be paid any additional amounts for soliciting proxies.

Parties to the Business Combination

Novus

Novus is a Delaware corporation and was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. Novus was formed to purse an initial business combination target in any industry or geographic location (subject to certain limitations described in this prospectus),

Novus Common Stock, Novus Warrants and Novus Units (each Novus Unit comprising one share of Novus Common Stock and one-third of a Novus Warrant) are currently listed and trading on the NYSE under the ticker symbols “NXU,” “NXU WS” and “NXU.U,” respectively. We have applied to continue the listing of the Novus Common Stock and Novus Warrants on the NYSE under the symbols “NRGV” and “NRGV WS,” respectively, upon Closing. The Novus Units will automatically separate into their component securities (one share of Novus Common Stock and one-third of a Novus Warrant) upon Closing and, as a result, will no longer exist. Upon Closing, Novus intends to change its name from “Novus Capital Corporation II” to “Energy Vault Holdings, Inc.”

The mailing address of Novus’s principal executive office is 8556 Oakmont Lane, Indianapolis, IN 46260, and its telephone number is (317) 590-6959.

Merger Sub

The Merger is to become effective by the filing of a certificate of merger with the Secretary of State of the State of Delaware, in accordance with the relevant provisions of the DGCL and mutually agreed by the parties, and will be effective immediately upon such filing or upon such later time as may be agreed by the parties and specified in such certificate of merger (such time, “Effective Time”). The parties will hold the Closing immediately prior to such filing of a certificate of merger, on the Closing Date.

The Effective Time shall occur as promptly as practicable but in no event later than three business day after the satisfaction or, if permissible, waiver of the conditions to the completion of the Business Combination set forth in the Business Combination Agreement (other than those conditions that by their nature are to be satisfied at Closing, provided that the occurrence of the Closing shall remain subject to the satisfaction or, if permissible, waiver at the Closing). Immediately prior to the Effective Time, Energy Vault shall cause each share of Energy Vault Preferred Stock that is issued and outstanding immediately prior to the Effective Time to be automatically converted into a number of shares of Energy Vault Common Stock at the then effective conversion rate as calculated pursuant to Energy Vault’s amended and restated certificate of incorporation. All of the shares of Energy Vault Preferred Stock converted into shares of Energy Vault Common Stock shall no longer be outstanding and shall cease to exist, and each holder of Energy Vault Preferred Stock shall thereafter cease to have any rights with respect to such securities.

At the Effective Time, by virtue of the Merger and without any action on the part of Novus, Merger Sub, Energy Vault or the holders of any of Energy Vault’s securities:

•

Each share of Energy Vault Common Stock issued and outstanding immediately prior to the Effective Time will be cancelled and automatically converted into the right to receive the number of shares of Combined Company Common Stock equal to the Exchange Ratio and all shares of Energy Vault Common Stock subject to forfeiture to or repurchase by Energy Vault shall retain such restrictions following conversion into Combined Company Common Stock;

•

All shares of Energy Vault Common Stock and Energy Vault Preferred Stock held in the treasury of Energy Vault shall be canceled without any conversion thereof and no payment or distribution shall be made with respect thereto;

•

Each share of Merger Sub Common Stock issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of common stock, par value $0.001 per share, of the Surviving Corporation;

•

Each Energy Vault Option that is outstanding immediately prior to the Effective Time, whether vested or unvested, shall be assumed, converted and/or substituted by Novus into an option to purchase a number of shares of Combined Company Common Stock (each such option, an Exchanged Option) equal to the product (rounded down to the nearest whole number) of (x) the number of shares of Energy Vault Common Stock subject to such Energy Vault Option immediately prior to the Effective Time and (y) the Exchange Ratio, and at an exercise price per share (rounded up to the nearest whole cent) equal to (A) the exercise price per share of such Energy Vault Option immediately prior to the Effective Time divided by (B) the Exchange Ratio, subject to adjustments related to Section 409A and Section 422 of the Code;

•

Each award of outstanding restricted stock units to acquire shares of Energy Vault Common Stock issued pursuant to an award granted under the 2017 Plan or otherwise (each an “Energy Vault RSU”), whether vested or unvested, that is outstanding immediately prior to the Effective Time shall be assumed, converted and/or substitutes by Novus into an award of restricted stock units to acquire shares of Combined Company Common Stock (each, a Converted RSU Award). Each Converted RSU Award will represent the right to acquire that number of shares of Combined Company Common Stock equal to the product (rounded down to the nearest whole number) of (1) the number of shares of Energy Vault Common Stock subject to the Energy Vault RSU award immediately before the Effective Time and (2) the Exchange Ratio; provided, that, except as specifically described above, following the Effective Time, each Converted RSU Award shall continue to be governed by the same terms and conditions (including vesting terms) as were applicable to the corresponding former Energy Vault RSU award immediately prior to the Effective Time.

•

Each award of outstanding restricted shares of Energy Vault Common Stock issued pursuant to a grant agreement under the 2017 Plan or otherwise (each an Energy Vault Restricted Share Award), whether vested or unvested, that is outstanding immediately prior to the Effective Time shall be assumed, converted and/or substituted by Novus into a restricted stock award with respect to a number of shares of Combined Company Common Stock equal to the product (rounded down to the nearest whole number) of (x) the number of shares of Energy Vault Common Stock subject to such Energy Vault Restricted Share Award immediately prior to the Effective Time and (y) the Exchange Ratio, with the same terms and conditions as were applicable under such Company Restricted Share Award immediately prior to the Effective Time.

•

No certificates or scrip or shares representing fractional shares of Combined Company Common Stock shall be issued upon the exchange of Energy Vault Common Stock and such fractional share interests will not entitle the owner thereof to vote or to have any rights of a stockholder of Novus or a holder of shares of Combined Company Common Stock. In lieu of any fractional share of Combined Company Common Stock to which each holder of Energy Vault Common Stock would otherwise be entitled, the fractional share shall be rounded up or down to the nearest whole share of Combined Company Common Stock, with a fraction of 0.5 rounded up. No cash settlements shall be made with respect to fractional shares eliminated by rounding.

For more information about the Lock-Up Agreements and Registration Rights, see the sections titled “Certain Agreements Related to the Business Combination — Lock-Up Agreements” and “Certain Agreements Related to the Business Combination — Registration Rights Agreement.”

Sponsor Restricted Stock Agreement

In connection with the Closing, the Novus Initial Stockholders and certain stockholders of Energy Vault will agree, that the Restricted Shares shall be subject to the transfer restrictions set forth herein until satisfaction of the following trigger events (each, a “Triggering Event”):

(a)

808,594 Founder Shares (approximately 11.125% of the Founder Shares) shall be released upon the date on which (x) the closing price of the Novus Common Stock (as adjusted for share splits, share capitalizations, reorganizations, recapitalizations and the like) exceeds $12.50 per share for any 20 trading days within a 30-trading day period occurring from the announcement of the PIPE through the thirty-six (36) month anniversary of the Closing Date or (ii) the closing of a sale, merger, the remaining Lock-Up Shares liquidation, or exchange offer transaction after the closing date of the Business Combination which results in the stockholders of the Combined Company having the right to exchange their shares of Novus Common Stock for cash, securities or other property having a value of at least $12.50 per share.

(b)

808,594 Founder Shares (approximately 11.125% of the Founder Shares) shall be released upon the date on which (x) the closing price of the Novus Common Stock (as adjusted for share splits, share capitalizations, reorganizations, recapitalizations and the like) exceeds $15.00 per share for any 20 trading days within a 30-trading day period occurring from the announcement of the PIPE through the thirty-six (36) month anniversary of the Closing Date or (ii) the closing of a sale, merger, the remaining Lock-Up Shares liquidation, or exchange offer transaction after the closing date of the Business Combination which results in the stockholders of the Combined Company having the right to exchange their shares of Novus Common Stock for cash, securities or other property having a value of at least $15.00 per share.

(c)

3,234,375 Founder Shares (approximately 66 2/3% of the 67.5% of the Founder Shares not subject to Section 2 or Section 4.1(a) or (b) above, (or 45.0% of the Founder Shares), shall be subject to forfeiture (the “Forfeiture Percentage”) proportionately with redemptions of cash from the Trust Account held by the Trustee in excess of $25,000,000. The Forfeiture Percentage shall be calculated by (1) dividing (A) the aggregate dollar amount of cash redeemed from the Trust Account in excess of $25,000,000 by (B) $287,500,000 and then (2) multiplying the quotient obtained in subsection (c)(1) by 45.0% of the Founder Shares. Notwithstanding the foregoing, in the event that more than 26,250,000 shares of Novus Common Stock are redeemed from the Trust Account (resulting in $262,500,000 of cash redeemed from the Trust Account assuming a redemption price of $10.00 per share), such 3,234,375 Founder Shares shall be forfeited in lieu of applying the Forfeiture Percentage.

For example, if holders of SPAC shares redeem a number of shares which reduces the cash in the Trust Account by $25,000,000 plus 25% of $287,500,000, (i.e. reduces the Trust Account by $96.875 million) the Founder Shares would be treated as follows:

$71,875,000 = 25% the aggregate dollar amount of cash redeemed from the Trust Account in excess of $25,000,000 (based on $96,875,000 total redeemed from the Trust Account)

$71,875,000/$287,500,000 = 25% (45.0% of 75% of the Founder Shares impacted negatively by 25%, which is the Forfeiture Percentage).

TABLE OF CONTENTS

45.0% of the Founder Shares would be reduced by the Forfeiture Percentage of 25% (i.e., 11.25% of the Founder Shares would be forfeited).

The remaining 1,617,187 Founder Shares (approximately 22.5% of the Founder Shares) are not Restricted Shares and are not subject to the vesting restrictions or forfeiture provisions set forth in clauses (a)-(c) above.

Stockholder Support Agreement

On September 8, 2021, Novus, Energy Vault and certain stockholders of Energy Vault entered into the Stockholder Support Agreement (the “Stockholder Support Agreement”) pursuant to which such stockholders agreed to vote all of their shares of Energy Vault Common Stock and Energy Vault Preferred Stock in favor of the approval and adoption of the Proposed Transactions. Additionally, such stockholders have agreed, among other things, not to (a) transfer any of their shares of Energy Vault Common Stock and Energy Vault Preferred Stock (or enter into any arrangement with respect thereto), subject to certain customary exceptions or (b) enter into any voting arrangement that is inconsistent with the Stockholder Support Agreement.

Energy Vault may terminate the Software Agreement by giving written notice to Palantir within 20 business days of (a) the final expiration of termination of the Subscription Agreement with Palantir before the consummation of such agreement or (b) the failure of the Business Combination to close for any reason.

TABLE OF CONTENTS

Interests of the Founders and Novus Directors and Officers in the Business Combination

In considering the recommendation of Novus’s board of directors to vote in favor of the Business Combination, stockholders should be aware that, aside from their interests as stockholders, our directors and officers have interests in the Business Combination that are different from, in addition to, or in conflict with those of other stockholders generally. Our directors were aware of and considered these interests, among other matters, in evaluating the Business Combination, and in recommending to stockholders that they approve the Business Combination. Stockholders should take these interests into account in deciding whether to approve the Business Combination. These interests include:

•

Messrs. Robert J. Laikin, Chief Executive Officer, a director and a principal stockholder of Novus, Larry Paulson, Chairman of the Board and a principal stockholder of Novus, and Jeffrey Foster, a director of Novus, each purchased a non-controlling membership interests in Helena SPV for $250,000. Each such membership interest will equate to an indirect interest of 119,632 shares of Combined Company Common Stock. Based on the closing sale price of Novus Common Stock on the Record Date, each such individual’s membership interest has a value of $[ ] and will have an unrealized gain on this investment of $[•] (based on the closing sale price of the Novus Common Stock of $[ ] as of the Record Date);

•

Novus’s board of directors will not receive reimbursement for any out-of-pocket expenses incurred by them on Novus’s behalf incident to identifying, investigating and consummating a business combination to the extent such expenses exceed the amount not required to be retained in the Trust Account, unless a business combination is consummated;

•

the anticipated continuation of Larry Paulson, as a director of the Combined Company following the Closing;

•

These interests may influence Novus’s board of directors in making their recommendation that you vote in favor of the approval of the Business Combination Proposal and the other Stockholder Proposals.

Reasons for the Approval of the Business Combination

After careful consideration, Novus’s board of directors recommends that Novus’s stockholders vote “FOR” each Stockholder Proposal being submitted to a vote of Novus’s stockholders at the Novus special meeting of stockholders.

For a description of Novus’s reasons for the approval of the Business Combination and the recommendation of our board of directors, see the section titled “The Business Combination — Novus’s Board of Directors’ Reasons for the Approval of the Business Combination.”

Redemption Rights

Under the Existing Certificate of Incorporation, holders of Public Shares may elect to have their shares redeemed for cash at the applicable redemption price per share equal to the quotient obtained by dividing (a) the aggregate amount on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination, including interest not previously released to Novus to pay its income taxes or any other taxes payable, by (b) the total number of shares of Public Shares. However, Novus will not redeem any Public Shares to the extent that such redemption would result in Novus having net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Exchange Act) of less than $5.0 million. For illustrative purposes, based on funds in the Trust Account of approximately $287.5 million on [*], 2022, the estimated per share redemption price would have been approximately $10.00.

If a holder exercises its redemption rights, then such holder will be exchanging its shares of Novus Common Stock for cash and will no longer own shares of Novus Common Stock and will not participate in the future growth of the Combined Company, if any. Such a holder will be entitled to receive cash for its Public Shares only if it properly demands redemption and delivers its shares (either physically or electronically) to Novus’s transfer agent in accordance with the procedures described herein. See the section titled “The Special Meeting of Novus’s Stockholders — Redemption Rights” for the procedures to be followed if you wish to redeem your shares for cash.

Ownership of the Combined Company After the Closing

The ownership of the Combined Company will vary based on the number of Novus Public Stockholders that exercise their redemption rights. In each of the no redemption, illustrative redemption, and contractual maximum redemption scenarios as described below, the residual equity value owned by non-redeeming stockholders, taking into account the respective redemption amounts, is assumed to remain the deemed value of $10.00 per share. As a result of such redemption amounts and the assumed $10.00 per share value, the implied total equity value of the Combined Company, assuming no dilution from any of the Public Warrants, Private Warrants, Energy Vault Options, Energy Vault RSUs or the Earn Out Shares (“Additional Dilution Sources”), would be (a) $1,567,847,880 in the no redemption scenario, (b) $1,410,738,500 in the illustrative redemption scenario, and (c) $1,267,121,500, in the contractual maximum redemption scenario. Additionally, the sensitivity table below sets forth the potential additional dilutive impact of each of the Additional Dilution Sources in each redemption scenario. Increasing levels of redemption will increase the dilutive effects of these issuances on non-redeeming Public Stockholders.

The following table illustrates varying beneficial ownership levels in the Combined Company immediately following the consummation of the Business Combination assuming the levels of redemptions by the public stockholders indicated:

Summary of Risk Factors

In evaluating the Stockholder Proposals, Novus Stockholders should carefully read this proxy statement/prospectus and especially consider the factors discussed in the section entitled “Risk Factors.” Some of the risks related to Energy Vault’s business and industry, the Business Combination and risks of the Combined Company, are summarized below:

•

Energy Vault is an early stage company with a history of losses, and it expects to incur significant expenses and continuing losses for the foreseeable future, and it may not be able to achieve profitability in the future.

•

Energy Vault’s limited operating history and its rapidly evolving industry make it difficult to evaluate Energy Vault’s business, the risks and challenges it may face and future prospects.

TABLE OF CONTENTS

•

The engineering of Energy Vault’s systems is in continuous refinement to improve system cost and efficiency. There is no guarantee that it will be successful in implementing all improvements under the expected schedule.

•

There is no assurance that non-binding letters of intent and other indications of interest will be converted into binding order or sales. Customers may cancel or delay the non-binding letters of intent and other indications of interest in Energy Vault’s sales pipeline.

•

Energy Vault’s systems are based on established principles that are deployed in a novel way to create new technologies to store energy and potential customers may be hesitant to make a significant investment in Energy Vault’s technology or abandon the technology they are currently using.

•

Energy Vault’s systems include complex software and technology systems and do not have a meaningful history of operation, and there can be no assurance such systems and technology will perform as expected or that software, engineering or other technical defects will not be discovered until after a system is installed and operated by a customer. If Energy Vault’s EVx systems contain manufacturing or construction defects, its business and financial results could be harmed. In addition, the development and updating of these systems will require Energy Vault to incur potentially significant costs and expenses.

•

The performance and availability of Energy Vault’s products, services and systems may be affected by factors outside of its control, which could result in harm to its business and financial results.

•

If any of Energy Vault’s products are or are alleged to be defective in design or manufacturing or experience other failures, Energy Vault may be compelled to undertake corrective actions, which could adversely affect its business, prospects, operating results, reputation and financial condition.

•

Energy Vault’s systems’ performance may not meet its customers’ expectations or needs.

•

Energy Vault’s systems involve a lengthy sales and installation cycle, and if it fails to close sales on a regular and timely basis it could harm its business. Moreover, the long sales cycles for Energy Vault’s products may cause it to incur significant expenses without offsetting revenues.

•

The failure or inability of Energy Vault’s suppliers to deliver necessary components or raw materials for construction of its systems in a timely manner could cause installation delays, cancellations, penalty payments and damage to its reputation.

•

Concentration of ownership among the Combined Company’s executive officers, directors and their affiliates may prevent new investors from influencing significant corporate decisions.

•

Novus’s executive officers, directors, other Founders have agreed to vote in favor of the Business Combination, regardless of how the Public Stockholders vote.

•

The consummation of the Business Combination is subject to a number of conditions and if those conditions are not satisfied or waived, the Business Combination Agreement may be terminated in accordance with its terms and the Business Combination may not be completed.

•

Legal proceedings in connection with the Business Combination, the outcomes of which are uncertain, could delay or prevent the completion of the Business Combination.

•

A significant portion of Novus’s total outstanding shares are restricted from immediate resale but may be sold into the market in the near future. This could cause the market price of Novus Common Stock to drop significantly, even if our business is doing well.

•

Novus’s stockholders will have a reduced ownership and voting interests after the Business Combination and will exercise less influence over management.

SUMMARY UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following summary unaudited pro forma condensed combined financial information (the “Summary Pro Forma Information”) gives effect to the transaction contemplated by the Business Combination Agreement. The transaction will be accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, Novus will be treated as the “acquired” company for financial reporting purposes. Accordingly, the transaction will be reflected as the equivalent of Energy Vault issuing stock for the net assets of Novus, accompanied by a recapitalization whereby no goodwill or other intangible assets are recorded. Operations prior to the Business Combination will be those of Energy Vault. The summary unaudited pro forma condensed combined balance sheet data as of September 30, 2021 gives effect to the Business Combination, as if, it had occurred on September 30, 2021. The summary unaudited pro forma condensed combined statements of operations data for the nine months ended September 30, 2021 and year ended December 31, 2020 give effect to the Business Combination, as if it had occurred on January 1, 2020.

The Summary Pro Forma Information has been derived from, and should be read in conjunction with, the more detailed unaudited pro forma condensed combined financial information of the Combined Company appearing elsewhere in this proxy statement/prospectus and the accompanying notes to the unaudited pro forma condensed combined financial information. The unaudited pro forma condensed combined financial information is based upon, and should be read in conjunction with, the historical financial statements and related notes of Novus and Energy Vault for the applicable periods included in this proxy statement/prospectus. The Summary Pro Forma Information has been presented for informational purposes only and is not necessarily indicative of what the Combined Company’s financial position or results of operations actually would have been had the Business Combination been completed as of the dates indicated. In addition, the Summary Pro Forma Information does not purport to project the future financial position or operating results of the Combined Company.

The unaudited pro forma condensed combined financial information has been prepared using the assumptions below with respect to the potential redemption into cash of Novus’s common stock:

•

Assuming No Redemptions: This presentation assumes that no public stockholders of Novus exercise redemption rights with respect to their Public Shares for a pro rata share of the funds in the Trust Account.

•

Assuming Maximum Redemptions: This presentation assumes that stockholders holding 26,838,263 Public Shares will exercise their redemption rights for their pro rata share ($10.00 per share) of the funds in the Trust Account. Redemption payments of $268.4 million will result in forfeiture of 3,234,375 Founder shares. The Business Combination Agreement provides that consummating the Proposed Transaction is conditioned on Novus having a minimum of $170 million of cash on hand (which is inclusive of $150,000,050 from the PIPE) whether in or outside the Trust Account after giving effect to Novus’s share redemptions and forfeiture of specified percentage of Founder shares if redemptions of cash from the Trust Account held by the Trustee is in excess of $25,000,000

Risks Related to Energy Vault’s Business and Industry

We are an early stage company with a history of losses, and expect to incur significant expenses and continuing losses for the foreseeable future, and we may not be able to achieve profitability in the future.

Since our inception in October 2017, we have incurred significant net losses and have used significant cash in our business. As of December 31, 2020, we had an accumulated deficit of $37.6 million, and net losses of $24.2 million for the year ended December 31, 2020 and $18.6 million for the nine months ended September 30, 2021. We expect to continue to expand our operations, including by investing in manufacturing, sales and marketing, research and development and infrastructure to support our growth. We anticipate that we will incur net losses for the foreseeable future and, even if we begin to record revenue, there is no guarantee that we will become profitable. Our ability to achieve profitability in the future will depend on a number of factors, including:

•

successfully implementing our products on a commercial scale;

•

achieving meaningful sales volume;

•

the successful and timely development of a digital platform by our Energy Vault Solutions division;

•

attracting customers;

•

expanding into geographical markets;

•

our future customers’ ability to attract and retain financing partners who are willing to provide financing for sales on a timely basis and with attractive terms;

•

continuing to improve the expected useful life of our gravity-based energy storage technology and reducing our warranty servicing costs;

•

the cost of producing our EVx systems, including our mobile masses;

•

ability to execute on our strategy to reduce costs, in the amount and on the timing projected;

•

adding waste material, such as coal ash and wind turbine blades, in the production of mobile masses;

•

improving the efficiency and predictability of our construction processes;

•

entering into agreements with suppliers and service providers for the maintenance of our systems and other strategic relationships;

•

improving the effectiveness of our sales and marketing activities and any independent sales representatives that we may engage;

•

attracting and retaining key talent in a competitive marketplace;

•

the amount of stock-based compensation that Energy Vault recognizes in a given period;

•

identifying new opportunities for other business to integrate our product into their operations;

TABLE OF CONTENTS

•

fluctuations in the costs of steel and raw materials;

•

legal and commercial acceptance of the incorporation of waste material (including, but not limited to, coal ash) into our mobile masses; and

•

delays associated with obtaining construction permits and potential regulatory review.

Even if we do achieve profitability, we may be unable to sustain or increase our profitability in the future.

Our limited operating history and our rapidly evolving industry make it difficult to evaluate our business, the risks and challenges we may face and future prospects.

From our inception in October 2017 to the present, we have focused principally on developing and proving our fundamental gravity energy storage technology, formulating and implementing the EV1 design, and only recently designed the new EVx and EVRC platforms, which are the systems we are seeking to commercialize. As a result, we have a limited history operating our business, and therefore a limited history upon which you can base an investment decision. We have built only one EV1 system, which serves as a commercial demonstration unit, and we have not deployed any other systems as of the date of this prospectus/proxy statement. Further, we have not yet finalized the design of our EVx system or our EVRC platform.

Our EVx systems and our EVRC platform are new types of products in the rapidly evolving energy storage industry. In light of the fact that the entire energy sector is undergoing a major transition, from thermal generation to renewable energy generation, predicting our future revenue depends on the evolution of the market itself and market acceptance of our technology and systems. Moreover, budgeting for our expenses presents some uncertainty because of the unpredictability of the prices of raw materials and other trends that may emerge and affect our business. If actual results differ from our estimates or we adjust our estimates in future periods, our operating results and financial position could be materially and adversely affected. You should consider our prospects in light of the risks and uncertainties emerging companies encounter when introducing new products into a nascent industry.

The engineering of our systems is in continuous refinement to improve system cost and efficiency. There is no guarantee that we will be successful in implementing all improvements under the expected schedule.

Our business depends on our ability to succeed in implementing our EVx systems and EVRC platform and introduce innovative and competitive energy storage technologies. As of the date of this proxy statement/prospectus, we have not deployed a fully operational EVx system or EVRC platform. As our EVx systems are highly complex, this process is costly and time-consuming. Further, we have not yet finalized the design of our EVx system or our EVRC platform. The date of the first EVx deployment may be delayed, and we may incur more costs than we expect. In addition, the processes by which we engineer and manufacture mobile masses are still developing rapidly as we explore new processes and different techniques. Our business, reputation, results of operations and financial condition may be materially adversely affected if we do not successfully implement our systems or to the extent that such implementation occurs later or costs more than we expect. Examples of costs that we cannot control include the costs of electronics due to global allocation shortages or costs associated with construction delays.

Our ability to use net operating loss (“NOL”) carryforwards and other tax attributes may be limited in connection with the proposed Business Combination and other ownership changes.

As stated above, we have incurred significant net losses during our history and our ability to become profitable in the near future is uncertain. To the extent that we continue to generate taxable losses, unused losses will carry forward to offset future taxable income, if any, until such unused losses expire (if at all). As of December 31, 2020, we had approximately $7.5 million, $10.2 million and $16.0 million of federal, state and foreign net operating loss carryforwards (“NOLs”) and $0.09 million and $0.05 million federal and state research and development tax credits.

Federal NOLs incurred in tax years beginning after December 31, 2017 and before January 1, 2021 may be carried back to each of the five tax years preceding such loss, and NOLs arising in tax years beginning after December 31, 2020 may not be carried back. Moreover, federal NOLs generated in taxable years

TABLE OF CONTENTS

ending after December 31, 2017, may be carried forward indefinitely, but the deductibility of such federal NOLs may be limited to 80% of our taxable income annually for tax years beginning after December 31, 2020. Our NOL carryforwards are subject to review and possible adjustment by the Internal Revenue Service (the “IRS”), and state tax authorities. In addition, in general, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-change NOLs or tax credits to offset future taxable income or taxes. For these purposes, an ownership change generally occurs where the aggregate stock ownership of one or more stockholders or groups of stockholders who own at least 5% of a corporation’s stock increases their ownership by more than 50 percentage points over their lowest ownership percentage within a specified testing period. Our existing NOLs or credits may be subject to limitations arising from previous ownership changes, and if we undergo an ownership change in connection with, or undergo an ownership change following, the proposed Business Combination, our ability to utilize NOLs or credits could be further limited by Sections 382 and 383 of the Code. In addition, future changes in our stock ownership, many of which are outside of our control, could result in an ownership change under Sections 382 and 383 of the Code. Our NOLs or credits may also be impaired under state law. Accordingly, we may not be able to utilize a material portion of our NOLs or credits. If we determine that an ownership change has occurred and our ability to use our historical NOLs or credits is materially limited, it would harm our future operating results by effectively increasing our future tax obligations. Section 382 and 383 of the Code would apply to all net operating loss and tax credit carryforwards, whether the carryforward period is indefinite or not. If we earn taxable income, such limitations could result in increased future tax liability to us and our future cash flows could be adversely affected.

Our systems are based on established principles that are deployed in a novel way to create new technologies to store energy and potential customers may be hesitant to make a significant investment in our technology or abandon the technology they are currently using.

The design of our EVx systems and EVRC platform are based on established principles that are deployed in a novel way and will compete with alternative energy storage products based on other technologies, like lithium-ion battery technology. We believe that the continued growth and acceptance of energy storage generally will depend significantly on continued investment by the public and private sectors in the renewable energy industry, the regulatory environment towards carbon intensive power generation and the speed of transition towards electric mobility.

The adoption of renewable energy may not proceed as quickly as (or at the levels that) we expect and may be influenced by changes in regulatory environments, including incentives, fuel prices, public policy concerns and other factors beyond our control. Additionally, potential customers who previously invested in alternatives to our gravity based energy storage solution may not deem a transition to our existing or future gravity based energy storage solutions to be cost-effective. Moreover, given the limited history of our gravity based energy storage technology, potential customers may be hesitant to make a significant investment in our products. Our business, results of operations, financial condition and prospects could be adversely affected to the extent that customers, for any reason, do not adopt our systems or migrate to our systems from another energy storage technology.

Our systems include complex software and technology systems and do not have a meaningful history of operation, and there can be no assurance such systems and technology will perform as expected or that software, engineering or other technical defects will not be discovered until after a system is installed and operated by a customer. If our EVx systems contain manufacturing or construction defects, our business and financial results could be harmed. In addition, the development and updating of these systems will require us to incur potentially significant costs and expenses.

To date, we have only built the CDU but have not yet deployed any EVx system or an EVRC, and these systems do not have any history of commercial operation. Once commercial production commences or our systems are installed and put into use by customers, our EVx systems, or any of our other products, may contain defects in design, manufacture or construction that may cause them not to perform as expected or may require repair. Because there is as of yet no prototype for our EVx systems or EVRCs and such systems are still under development, we currently have no frame of reference by which to evaluate the performance of our EVx systems and EVRCs upon which our business prospects depend. For example, our EVx systems

TABLE OF CONTENTS

and any EVRC will use a substantial amount of software to operate which may require modification and updates over the life of such systems. Software products are inherently complex and often contain defects and errors when first introduced. Additionally, it is difficult for us to evaluate the manufacture and construction of our EVx systems or an EVRC until there are working examples that have been manufactured, constructed and used by us and/or our customers.

There can be no assurance that we will be able to detect and fix any defects in the hardware or software of our EVx systems or EVRCs, and such defects may not become apparent until a system is installed and operated by a customer. Our EVx systems and EVRCs may not perform consistent with customers’ expectations or consistent with other energy storage systems which may become available. Any product defects or any other failure of our EVx systems to perform as expected could harm our reputation and result in negative publicity, lost revenue, delivery delays, product liability claims and significant warranty and other expenses, and could have a material adverse impact on our business, financial condition, operating results and prospects.

In addition, further development and updating of our EVx systems and EVRC platform will require us to incur potentially significant costs and expenses.

The performance and availability of our products, services and systems may be affected by factors outside of our control, which could result in harm to our business and financial results.

The performance and availability of our products, services and systems may be affected by factors outside of our control, such as inclement weather and natural disasters, failures in the power grid, acts of vandalism, shortages in skilled and qualified technical and construction personnel, shortages in raw materials or spare parts, fluctuations in commodities prices, bad performance or poor quality of equipment and/or infrastructure purchased from our suppliers and unforeseeable incidents or mistakes in the construction, commissioning or testing of prototype sites under the control of Energy Vault. The severity of such factors and frequency at which they occur are also outside our control. If such factors occur and affect the performance of our systems, our business and financial results could be harmed.

If any of our products are or are alleged to be defective in design or manufacturing or experience other failures, we may be compelled to undertake corrective actions, which could adversely affect our business, prospects, operating results, reputation and financial condition.

Once an EVRC or EVx system is delivered to a customer, some of the delivered product components may contain defects in design or manufacture that may cause them not to perform as expected or that may require repair and design changes. The EVRC and our EVx systems are complex and incorporate technology and components that may contain defects and errors, particularly when first introduced. We have a limited frame of reference from which to evaluate the long-term performance of our EVx systems and EVRCs in light of the fact that there is still no prototype for them. There can be no assurance that we will be able to detect and fix any defects in an EVRC or our EVx systems prior to the sale to potential consumers. If a mobile mass falls from an EVx system or an EVRC or our systems otherwise fail to perform as expected, customers may delay or cancel deliveries, generate negative publicity about us, terminate further orders or pursue warranty or other claims against us, each of which could adversely affect our sales and reputation and could adversely affect our business, prospects, and results of operations.

Our systems’ performance may not meet our customers’ expectations or needs.

The systems will be subject to various operating risks that may cause them to generate less value for our customers than expected. These risks include a failure or wearing out of our equipment or the equipment that our equipment connects into, an inability to find suitable replacement equipment or parts, or disruption in our distribution systems. Any extended interruption or failure of our customer’s projects, including systems we operate under the Storage Service Customer program, for any reason to generate the expected amount of output could adversely affect our business, financial condition and results of operations. In addition, our customers’ willingness to acquire additional systems or services from us may be impacted in the future if any of our systems incur operational issues that indicate expected future cash flows from the system are less than the carrying value. Any such outcome could adversely affect our operating results or ability to attract new customers.

TABLE OF CONTENTS

If our estimates of the useful life for our energy storage systems are inaccurate or we do not meet service and warranties and performance guarantees, our business and financial results could be adversely affected.

We expect to provide warranties and performance guarantees of our systems. To date, we have only deployed our CDU, and we have not deployed any EVx system or an EVRC, and our estimates about product performance and life may prove to be incorrect. Failure to meet these warranties and performance guarantee levels may require the purchase price to be adjusted downward based on agreed-upon performance targets, or require us to make cash payments to the customer based on actual performance, as compared to expected performance.

Further, the occurrence of any defects, errors, disruptions in service, or other performance problems, interruptions, or delays with our systems, whether in connection with day-to-day operations or otherwise, could result in:

•

loss of customers;

•

loss or delayed market acceptance and sales of our hardware and software-enabled services;

•

delays in payment to us by customers;

•

injury to our reputation and brand;

•

legal claims, including warranty and service level agreement claims, against us; or

•

diversion of our resources, including through increased service and warranty expenses or financial concessions, and increased insurance costs.

The costs incurred in correcting any material defects or errors in our hardware and software or other performance problems may be substantial and could adversely affect our business, financial condition and results of operations.

Through Energy Vault Solutions, we intend to continue exploring, the potential for offering, as a standalone product, a digital platform that could help energy storage businesses make decisions on when to charge their systems and when to sell their power. We are in the early stages of developing such a digital platform, and there is no assurance that a market for such a digital platform exists or that it would be as beneficial to us as we expect.

Through Energy Vault Solutions, we are in the early stages of exploring the potential for offering, as a standalone product, a digital platform that could help energy storage businesses make decisions on when to charge their systems and when to sell their power. We have begun developing this platform and we intend to continue this exploration. Even after we spend time and resources to develop such a digital platform and to explore the market potential for such a digital platform, there is no assurance that we will develop a product that can be sold on terms that are commercially acceptable to us. Moreover, even if we develop the digital platform and enter into sales agreements for it, these agreements may not be as beneficial to us as we expected at the time of entering into the underlying agreement. Any of the foregoing may adversely affect our business, financial condition, results or operations and prospects.

We intend to explore alternative, co-active use case opportunities for our systems, but there is no assurance that such opportunities exist or that they would be as beneficial to us as we expect.

We intend to explore alternative, co-active use case opportunities for our EVx systems. For example, we intend to explore opportunities in energy-intensive industries such as vertical farming, data centers, crypto mining, direct air carbon capture where our systems may be able to benefit from existing infrastructure, including physical enclosures and electrical systems, that are built into the designs for our EVx and EVRC systems. Even after we spend time and resources exploring such opportunities, there is no assurance that they exist on terms that are commercially acceptable to us. Moreover, even if we enter into agreements to make use of such opportunities, such opportunities may not be as beneficial to us as we expected at the time of entering into the underlying agreement. Any of the foregoing may adversely affect our business, financial condition, results or operations and prospects.

TABLE OF CONTENTS

Insufficient warranty reserves to cover future warranty claims could adversely affect our business, prospects, financial condition and operating results.

Once our EVx systems and EVRCs are in production, we will need to maintain warranty reserves to cover warranty-related claims. If the warranty reserves are inadequate to cover future warranty claims on our EVx systems or our EVRCs or any digital platform that we may develop, our business, prospects, financial condition and operating results could be materially adversely affected. We may become subject to significant and unexpected warranty expenses. There can be no assurances that then-existing warranty reserves will be sufficient to cover all claims.

The implementation of our business plan and strategy may require additional capital. If we are then unable to achieve sufficient sales to generate that capital or otherwise raise capital, it may create substantial doubt about our ability to pursue our business objectives and achieve profitability or to continue as a going concern. If adequate capital is not available to us, including due to the cost and availability of funding in the capital markets, our business, operating results and financial condition may be harmed.

The development, design, manufacture and sale of our energy storage systems is a capital-intensive business. As a result, we can be expected to continue to incur substantial operating expenses without generating sufficient revenues to cover expenditures. Over time, we may need to raise additional funds, including through entry into new joint venture arrangements, through the issuance of equity, equity-linked or debt securities or through obtaining credit from financial institutions to fund, together with our principal sources of liquidity, ongoing costs such as research and development relating to our products and technologies, the construction and tooling of prototypes, the implementation of our systems for our future customers, any significant unplanned or accelerated expenses, and new strategic investments. We cannot be certain that additional capital will be available on attractive terms, if at all, when needed, which could be dilutive to shareholders, and our financial condition, results of operations, business and prospects could be materially and adversely affected.

In addition, if adequate capital is not available to us, it may create substantial doubt among third parties, including suppliers and potential customers, about our ability to pursue our objectives, to achieve profitability or to continue as a going concern. Such doubt could adversely impact our business, reputation and prospects.

Our energy storage systems involve a lengthy sales and installation cycle, and if we fail to close sales on a regular and timely basis it could harm our business. Moreover, the long sales cycles for our energy storage systems may cause us to incur significant expenses without offsetting revenues

Although we have not yet completed any full cycle from sale to installation of our energy storage systems, we expect them to be lengthy. In order to make a sale, we must typically provide a significant level of education to prospective customers regarding the use and benefits of our product and our technology. The period between initial discussions with a potential customer and the sale of even a single product typically depends on a number of factors, including the potential customer’s attitude towards innovative products, their budget and decision as to the type of financing it chooses to use, as well as the arrangement of such financing. Prospective customers often undertake a significant evaluation process, which may further extend the sales cycle. Once a customer makes a formal decision to purchase our product, the fulfillment of the sales order by us requires a substantial amount of time. Currently, we believe the time between the entry into a sales contract with a customer and the installation of our EVx systems or an EVRC could range from 18 to 36 months or more. This lengthy sales and installation cycle is subject to a number of significant risks over which we have little or no control. Because of both the long sales and installation cycles, we may expend significant resources without having certainty of generating a sale.

These lengthy sales and installation cycles increase the risk that our customers fail to satisfy their payment obligations or cancel orders before the completion of the transaction or delay the planned date for installation. Generally, a customer can cancel an order prior to installation, and, notwithstanding the fact that a customer’s termination for convenience will obligate the customer to pay us certain fees, we may be unable to recover some of our costs in connection with design, permitting, installation and site preparations incurred prior to cancellation. Cancellation rates in our industry could increase in any given period, due to factors outside of our control including an inability to install an EVx system at the customer’s chosen location

TABLE OF CONTENTS

because of permitting or other regulatory issues, unanticipated changes in the cost or availability of alternative sources of electricity available to the customer, or other reasons unique to each customer. Our operating expenses are based on anticipated sales levels, and certain of our expenses are fixed. If we are unsuccessful in closing sales after expending significant resources or if we experience delays or cancellations, our business could be materially and adversely affected.

Moreover, our customers typically expend significant effort in evaluating, testing and qualifying our products before making a decision to purchase them, resulting in a lengthy initial sales cycle. While our customers are evaluating our products we have incurred, and expect to continue to incur, substantial sales, marketing and research and development expenses to customize our products to the customer’s needs. During an initial sales cycle, we may also expend significant management efforts and order long-lead-time components or materials. Even after this evaluation process, a potential customer may not purchase our products. As a result, these long sales cycles may cause us to incur significant expenses without ever receiving revenue to offset those expenses.

Because of the long sales cycles and the expected limited number of customers for our energy storage systems, our operating results will likely fluctuate significantly from quarter to quarter.

We expect that long sales cycles and the expected limited number of customers for our energy storage systems is likely to cause fluctuations in our operating results from quarter to quarter. In light of the standards under which we expect to recognize revenue, small fluctuations in the timing of the completion of our sales transactions could also cause operating results to vary materially from period to period. In addition, our financial condition and results of operations may fluctuate in the future due to a variety of factors, many of which are beyond our control. For example, the amount of revenue we recognize in a given period is expected to be materially dependent on the volume and scale of purchases of our EVx systems and our customers’ preferences for choosing to purchase the system or purchase the energy storage and dispatch of electricity from systems we build and in which we retain an ownership interest.

In addition to the other risks described herein, the following factors could also cause our financial condition and results of operations to fluctuate on a quarterly basis:

•

fluctuations in costs associated with the first group of EVx systems that we deploy;

•

the timing of customer installations of our EVx systems, which may depend on many factors such as availability of inventory, product quality or performance issues, or local permitting requirements, utility requirements, environmental, health and safety requirements, weather and customer facility construction schedules, availability and schedule of our third-party general contractors;

•

size of particular customer installations and number of sites involved in any particular quarter;

•

delays or cancellations of purchases and installations;

•

fluctuations in our service costs;

•

weaker than anticipated demand for our energy storage systems due to changes in government regulation, incentives and policies;

•

interruptions in our supply chain;

•

the timing and level of additional purchases by existing customers;

•

unanticipated expenses incurred due to changes in governmental regulations, permitting requirements by local authorities at particular sites, utility requirements and environmental, health and safety requirements;

•

disruptions in our sales, production, service or other business activities resulting from our inability to attract and retain qualified personnel;

•

shortage of raw materials from our suppliers and associated price increases due to fluctuations in commodities prices; and

•

availability of spare parts from our suppliers.

TABLE OF CONTENTS

In addition, our revenue, key operating metrics and other operating results in future quarters may fall short of the expectations of investors and financial analysts, which could have an adverse effect on the price of our common stock.

There is no assurance that we will be able to execute on our business model, including achieving market acceptance of our planned products or identifying potential customers.

Investors should be aware of the difficulties normally encountered by a new enterprise, many of which are beyond our control, including substantial risks and expenses in the course of establishing or entering new markets, developing and commercializing new products and technologies, organizing operations and undertaking marketing activities. The likelihood of our success must be considered in light of these risks, expenses, complications, delays and the competitive environment in which we operate. There is, therefore, nothing at this time upon which to base an assumption that our business plan will prove successful, and we may not be able to generate significant revenue, raise additional capital or operate profitably. We will continue to encounter risks and difficulties frequently experienced by pre-commercial and early commercial stage companies, including scaling up our infrastructure and headcount, and may encounter unforeseen expenses, difficulties or delays in connection with our growth. Any investment in our company is therefore highly speculative and could result in the loss of your entire investment.

The size of our energy storage systems may negatively impact our ability to enter into contracts with customers or obtain government permits and approvals.

Our EVx systems require a considerably larger space for their deployment than comparable systems based on certain technologies such as lithium-ion technology, and this can result in a significant delay in the permitting process. In addition, the size of our EVx systems may represent an impediment for the deployment of our EVx systems in denser areas or areas with restrictions on the height of buildings. And, in light of the size of our systems, we require hard soil or the ability to get to bedrock in order to deploy our systems. These factors may negatively impact our ability to enter into customer contracts or obtain government permits and approvals, each of which may materially affect our business.

Our business is subject to risks associated with construction, cost overruns and delays, including those related to obtaining government permits and approvals, electrical interconnection, and other contingencies that may arise in the course of completing installations.

Our business is subject to risks relating to construction, cost overruns and delays. The installation and operation of our energy storage systems at a particular site is generally subject to oversight and regulation in accordance with national, state and local laws and ordinances relating to building codes, safety, environmental protection, FERC and specific Independent System Operators regulation and related matters, and typically requires obtaining and keeping in good standing various local and other governmental approvals and permits, including environmental approvals and permits, that vary by jurisdiction. In some cases, these approvals and permits require periodic renewal. It is difficult and costly to track the requirements of every individual authority having jurisdiction over energy storage system installations, to design our energy storage systems to comply with these varying standards, which may change over time, and for customers to obtain all applicable approvals and permits. We cannot predict whether or when all permits required for a given customer’s project will be granted or whether the conditions associated with the permits will be achievable. The denial of a permit or utility connection essential to a project or the imposition of impractical conditions would impair our customer’s ability to develop the project. In addition, we cannot predict whether the permitting process will be lengthened due to complexities and appeals. Delay in the review and permitting process for a project can impair or delay our customers’ abilities to develop that project or increase the cost so substantially that the project is no longer attractive to our customers. Furthermore, unforeseen delays in the review and permitting process could delay the timing of the installation of our energy storage systems and could therefore adversely affect the timing of the recognition of revenue related to hardware acceptance by our customer, which could adversely affect our operating results in a particular period. Delays relating to constructions may also bring about cost overruns, which could further adversely affect our business.

In addition, the successful installation of our energy storage systems is dependent upon the availability of and timely connection to the local electric grid. Before beginning construction on an EVx system, we may

TABLE OF CONTENTS

be unable to obtain in a timely fashion or at all the required consent and authorization of local utilities to ensure successful interconnection to energy grids to enable the successful discharge of renewable energy to customers. Any delays in our customers’ ability to connect with utilities, delays in the performance of installation-related services or poor performance of installation-related services will have an adverse effect on our results and could cause operating results to vary materially from period to period.

The failure or inability of our suppliers to deliver necessary components or raw materials for construction of our energy storage systems in a timely manner could cause installation delays, cancellations, penalty payments and damage to our reputation.

We rely on a limited number of third-party suppliers for some of the raw materials and components for our EVx systems, including steel, cement, polymers and, in certain cases, coal ash waste and retired wind turbine blades, and other materials that may be of limited supply. If any of our suppliers provide insufficient inventory at the level of quality required or if our suppliers are unable or unwilling to provide us with the contracted quantities (as we have limited or in some case no alternatives for supply), our results of operations could be materially and negatively impacted. If we fail to develop or maintain our relationships with any of our suppliers, or if there is otherwise a shortage or lack of availability of any required raw materials or components, we may be unable to manufacture our EVx systems or EVRCs or such products may be available only at a higher cost or after a long delay. For example, there has recently been a shortage of microchips, which has affected certain manufacturers, and if such shortage continues, our business could be affected as our products incorporate microchips. Such delays could prevent us from delivering our EVx systems or our EVRCs to customers within required time frames and cause order cancellations. These activities are time and capital intensive. Accordingly, the number of suppliers we have for some of our components and materials is limited and, in some cases, sole sourced. We may be unable to obtain comparable components from alternative suppliers without considerable delay, expense, or at all. If our suppliers face difficulties obtaining the credit or capital necessary to expand their operations when needed, they could be unable to supply necessary raw materials and components needed to support our planned sales and services operations, which would negatively impact our sales volumes and cash flows.

Moreover, we have in the past and may in the future experience unanticipated disruptions to operations or other difficulties with our supply chain or internalized supply processes due to exchange rate fluctuations, volatility in regional markets from where materials are obtained, changes in the general macroeconomic outlook, global trade disputes, political instability, expropriation or nationalization of property, public health emergencies such as the COVID-19 pandemic, civil strife, strikes, insurrections, acts of terrorism, acts of war, or natural disasters. The failure by us to obtain raw materials or components in a timely manner or to obtain raw materials or components that meet our quantity and cost requirements could impair our ability to manufacture our products or increase their costs or the associated service costs of under maintenance services agreements, if any are entered into. If we cannot obtain substitute materials or components on a timely basis or on acceptable terms, we could be prevented from delivering our EVx systems to customers within required time frames, which could result in sales and installation delays, cancellations, penalty payments, or damage to our reputation, any of which could have a material adverse effect on our business and results of operations. In addition, we rely on our suppliers to meet quality standards, and the failure of our suppliers to meet or exceed those quality standards could cause delays in the delivery of our products, cause unanticipated servicing costs, and cause damage to our reputation.

Our future growth is dependent upon the pace and depth of renewable energy adoption and energy storage technologies, which are emerging industries, as well as our competition. If the markets for renewable energy and energy storage do not develop as we expect, or if they develop more slowly than we expect, our business, prospects, financial condition and operating results could be adversely affected.

Our future growth depends upon factors in our industry, including with respect to our competition, the speed at which the market adopts renewable energy, our ability to penetrate such market and the state of energy storage technologies. Because renewable energy and energy storage are emerging industries, they are evolving and characterized by rapidly changing technologies, changing government regulation and industry standards and changing consumer demands and behaviors. If the markets for these do not develop as we expect, including if they develop more slowly than we expect, demand for our EVx systems, our EVRCs or

TABLE OF CONTENTS

any digital platform that we may develop, our business, prospects, financial condition and operating results could be adversely affected.

Additionally, the energy storage market is largely driven by installed capacity of renewable electricity generation and increasing demand for renewable sources of power. Since many of these renewable sources of power are intermittent, like wind and solar, the energy produced by them must be stored for use when there is demand. Should government requirements for these intermittent power sources be relaxed or social desires for lower-carbon sources of energy decline, there could be a detrimental impact on one of our primary markets.

Even if renewable energy and energy storage become more widely adopted, our gravity energy storage technology may not achieve widespread market acceptance or may be less cost-effective as compared to competing technologies.

Our business depends on the acceptance of our products, including the EVx systems, in the marketplace. Even if renewable energy and energy storage become more widely adopted than they have been to date, potential customers may choose energy storage products from our competitors that are based on technologies other than gravity energy storage, for example, lithium-ion battery technology. If they do so, it may be difficult to later transition such potential customers to products offered by us. Moreover, the marketplace for renewable energy storage products is rapidly evolving, and competing technologies of which we are currently unaware may emerge in the future. If the gravity energy storage technology that supports our products, including the EVx systems, does not achieve market acceptance then our business and results of operations would be materially adversely affected.

The growth and profitability of our business is dependent upon our technology being more cost-effective than competing energy storage technologies. For example, over the last decade, the cost of battery storage systems, particularly lithium-ion based battery storage systems, has declined significantly. If the cost of competing technologies, including battery storage systems, declines sufficiently, our gravity energy storage technology system may be less cost-effective for potential customers, which would decrease the demand for our products. Such a decrease in demand would materially adversely affect our business, prospects and results of operations.

If we are not able to reduce our cost structure in the future, our ability to become profitable may be impaired.

Over time, we must effectively manage the manufacturing costs for our EVx systems to expand our market. While we have sought, and will continue to seek, to manage our manufacturing and services costs, the cost of components and raw materials, for example, could increase in the future. Any such increases could slow our growth and cause our financial results and operational metrics to suffer. In addition, we may face increases in our other expenses, including increases in wages or other labor costs, as well as installation, marketing, sales or related costs. We may continue to make significant investments to drive growth in the future. To the extent that the price of electricity from the grid is low in certain markets, we will need to continue to reduce our costs to maintain our expected margins in those markets. Increases in any of these costs or our failure to achieve projected cost reductions could adversely affect our results of operations and financial condition and harm our business and prospects. If we are unable to reduce our cost structure sufficiently in the future, we may not be able to achieve profitability, which could have a material adverse effect on our business and prospects.

We have experienced rapid internal growth and expect to invest in our growth for the foreseeable future. If we fail to manage our growth effectively, our business and operating results may suffer.

In recent periods, our internal operations have grown in terms of complexity and the number of our employees, and we intend to continue such investment for the foreseeable future. The growth and expansion of our business has placed and continues to place a strain on management, operations, financial infrastructure and corporate culture. In the event of further growth, our information technology systems and our internal control over financial reporting and procedures may not be adequate to support our operations and may introduce opportunities for data security incidents that may interrupt business operations

TABLE OF CONTENTS

and permit bad actors to obtain unauthorized access to business information or misappropriate funds. We may also face risks to the extent such bad actors infiltrate the information technology infrastructure of our contractors.

To manage growth in operations and personnel, we will need to continue to improve our operational, financial and management controls and reporting systems and procedures. Failure to manage growth effectively could result in difficulty or delays in attracting customers, declines in quality or customer satisfaction, increases in costs, difficulties in introducing new products and services or enhancing existing products and services, loss of customers, information security vulnerabilities or other operational difficulties, any of which could adversely affect our business and results of operations.

If we are unable to attract and retain key employees and hire qualified management, technical, engineering, and sales personnel, including a highly skilled and diverse management team with experience in the energy storage sectors, our ability to compete and successfully grow our business could be harmed.

We believe that our success and our ability to reach our strategic objectives are highly dependent on the contributions of our key management, technical, engineering and sales personnel. The loss of the services of any of our key employees could disrupt our operations, delay the development and introduction of our products and services, including with respect to our prototype products, and negatively impact our business, prospects and operating results. In particular, we are highly dependent on the services of Robert Piconi, our Chief Executive Officer, Marco Terruzzin, our Chief Product Officer and Andrea Pedretti our Chief Technology Officer. None of our key employees is bound by an employment agreement for any specific term. We cannot assure you that we will be able to successfully attract and retain senior leadership necessary to grow our business. Furthermore, there is increasing competition for talented individuals in our field, and competition for qualified personnel is especially intense in the renewable energy and energy storage industry in the USA and Switzerland, where, collectively, our primary offices are located. Our failure to attract and retain our executive officers and other key technology, sales, marketing and support personnel, could adversely impact our business, prospects, financial condition, and operating results. In addition, we do not have “key person” life insurance policies covering any of our officers or other key employees.

We believe that it is vital to our operating success that we recruit and retain key personnel, including a highly skilled and diverse management team with experience in the renewable energy and energy storage sectors. If we fail to maintain a highly skilled and diverse management team, we may not be able to achieve our strategic objectives, which would negatively impact our business and operating success. In addition, because our industry is still in a nascent stage, there is and will continue to be a scarcity of skilled personnel with experience in our industry. If we lose a member of our management team or key employee, it may prove difficult for us to replace him or her with a similarly qualified individual with experience in the renewable energy and energy storage industry, which could impact our business and operating success.

Our EVx systems have significant upfront costs, and our customers may need to obtain financing to help finance purchases. If our customers are unable to procure third-party financing or if the cost of such financing exceeds our estimates, our business would be adversely affected.

Our EVx systems have significant upfront costs, and certain customers may need, or may prefer to acquire, third-party financing to purchase our systems.

Therefore, our growth, including the deployment of our EVx systems, may to an extent depend on our customers’ ability to attract third-party financing partners. Their ability to attract third-party financing depends on many factors that are outside of our control, including the ability of third parties to utilize tax credits and other government incentives, interest rate and/or currency exchange fluctuations, their perceived creditworthiness and the condition of credit markets generally. We expect that the financing of customer purchases of our EVx systems will be subject to customary conditions such as the customer’s credit quality, and if these conditions are not satisfied, such customers may be unable to finance purchases of our EVx systems, which would have an adverse effect on our revenue in a particular period. To the extent our customers are unable to arrange future financings for any of our current or potential projects, our business would be negatively impacted.

TABLE OF CONTENTS

In attempting to attract new customers to support our growth, we intend to refine our customer agreements based on experience. Moreover, new types of product offerings may require our customers to find partners willing to finance these new projects, which may have different terms and financing conditions from prior transactions. If the terms of these transactions or the structure of these projects fails to attract financiers, we may not be able to proceed with growing our business and our potential for growth may be limited. Additionally, financing options are also limited by the customer’s willingness to commit to making fixed payments regardless of the performance of the EVx systems or our performance of our obligations under the customer agreement

Further, our sales process for transactions that require financing require that we and our customers make certain assumptions regarding the cost of financing capital. If the cost of financing ultimately exceeds our estimates, we may be unable to proceed with some or all of the impacted projects or our revenue from such projects may be less than our estimates. Actual financing costs for potential customers may vary from our estimates due to factors outside of our control, including changes in customer creditworthiness, macroeconomic factors, the returns offered by other investment opportunities available to our financing partners, and other factors.

If our customers are unable to procure financing partners willing to finance deployments of our products or if the cost of such financing exceeds our estimates, our business would be negatively impacted.

We face additional risks to the extent that customers choose to purchase energy storage and dispatch of electricity from systems we build and in which retain an ownership interest rather than purchase an energy storage system.

We expect to offer our customers a choice of two programs. Under the first program, Storage Asset Owners, the customer owns both the energy storage system and the service the system provides (the energy storage and dispatch of electricity). We anticipate that this program will constitute the substantial majority of future sales. Under the second program, Storage Service Customers program, customers purchase the energy storage and dispatch of electricity from us while we retain an ownership interest in the system, together with financing partners.

We could face additional risks under the Storage Service Customers program that we would not otherwise face under our Storage Asset Owners program. For example, we would need to seek equity and/or debt financing to fund the construction and operation of any energy systems built in connection with a project for a customer who chooses the Storage Service Customers program. Such financing may not be available on terms acceptable to us, if at all. Moreover, we expect that any such indebtedness would be secured by a lien on the related energy storage system, and the governing debt agreement may contain covenants imposing operating and financial restrictions on our operations. In addition, until any such debt is repaid, we may not be able to generate meaningful cash flow from the project. Moreover, the failure of our customers to make payments could trigger an event of default under such governing debt agreements, which could result in the acceleration of repayment of our outstanding indebtedness or even entitle our lender to foreclose on the collateral securing our debt. In addition, to the extent equity financing is also used, our right to receive cash flows from the project could be subordinated to the other equity investors.

Additionally, there could be a material adverse effect on our operating results and our cash flows to the extent we own and operate our energy storage systems for the benefit of customers who choose the Storage Services Customers program. For example, we would not expect to receive any payments from the customer until the system is completed and expenses relating to insurance premiums, personnel and our interest payments under debt agreements would be increased, and such increases may be material. We could also be required to provide ongoing maintenance and repair services or could face liability for any damages or injuries if the system malfunctions. Additionally, we would be subject to the risks of termination of the agreement by the customer and the inability to replace the customer would result in the system failing to generate revenue. We may also incur liabilities as a result of a performance failure or other breach of our obligations in connection with the operation of the system

We may also be subject to additional legal and regulatory restrictions to the extent we own and operate an energy storage system, including relating to the transmission of energy. Such legal and regulatory

TABLE OF CONTENTS

restrictions could increase the costs of compliance and potentially subject us to threatened or actual litigation or administrative proceedings, each of which could have a material adverse affect on our business, operating results and financial condition.

Although we expect the significant majority of the revenue from our two programs to be from the Storage Asset Owners program based on our current outlook, there is no assurance that the Storage Services Customers program will not account for a significant portion of our business.

Our operations are international, and expanding operations in some international markets could expose us to additional risks.

Our operations are international, and we continue to expand our business internationally as we seek to partner with customers, suppliers and other partners around the world. We currently have operations relating to the EV1 in Switzerland, and our signed purchase order and letters of intent are with counterparties around the world. Managing further international expansion will require additional resources and controls including additional manufacturing and assembly facilities. Any expansion internationally could subject our business to risks associated with international operations, including:

•

conformity with applicable business customs, including translation into foreign languages and associated expenses;

•

lack of availability of government incentives and subsidies;

•

challenges in arranging, and availability of, financing for our customers;

•

potential changes to our established business model;

•

cost of alternative power sources, which could be meaningfully lower outside the United States;

•

availability and cost of raw materials, labor, equipment for manufacturing or assembling our EVx systems;

•

difficulties in staffing and managing foreign operations in an environment of diverse culture, laws, and customers, and the increased travel, infrastructure, and legal and compliance costs associated with international operations;

•

installation challenges which we have not encountered before which may require the development of a unique model for each country;

•

compliance with multiple, potentially conflicting and changing governmental laws, regulations, and permitting processes including construction, environmental, banking, employment, tax, privacy, safety, security, grid minimum performances, and data protection laws and regulations;

•

compliance with U.S. and foreign anti-bribery laws including the Foreign Corrupt Practices Act and the U.K. Anti-Bribery Act;

•

greater difficulties in securing or enforcing our intellectual property rights in certain jurisdictions, or in potential infringement of third-party intellectual property rights in new jurisdictions;

•

difficulties in collecting payments in foreign currencies and associated foreign currency exposure;

•

restrictions on repatriation of earnings;

•

compliance with potentially conflicting and changing laws of taxing jurisdictions where we conduct business and compliance with applicable U.S. tax laws as they relate to international operations, the complexity and adverse consequences of such tax laws, and potentially adverse tax consequences due to changes in such tax laws;

•

increases or decreases in our expenses caused by fluctuation in foreign currency exchange rates;

•

changes in import tariffs imposed by local governments;

•

changes in regulations regarding the use of waste materials in our products;

•

changes in regulations that would prevent us from doing business in specified countries;

TABLE OF CONTENTS

•

failure of the supply chain in local countries to provide us with materials of a sufficient quality and quantity delivered on timelines we expect; and

•

regional economic and political conditions.

As a result of these risks, any potential future international expansion efforts that we may undertake may not be successful.

In addition, nearly all of our letters of intent are denominated in U.S. dollars, and certain of our definitive agreements could be denominated in currencies other than the U.S. dollar, including the euro, the Australian dollar, the Brazilian real and the Saudi riyal. A strengthening of the U.S. dollar could increase the cost of our solutions to our international customers, which could adversely affect our business and results of operations. In addition, an increasing portion of our operating expenses is incurred outside the United States, is denominated in foreign currencies, such as the euro and the Swiss franc, and is subject to fluctuations due to changes in foreign currency exchange rates. If we become more exposed to currency fluctuations and are not able to successfully hedge against the risks associated with currency fluctuations, our results of operations could be adversely affected.

Our projections are subject to significant risks, assumptions, estimates and uncertainties. As a result, our projected revenues, market share, expenses and profitability may differ materially from our expectations.

Our projections are subject to significant risks, assumptions, estimates and uncertainties. Such projections reflect our current views with respect to future events or our future financial performance, are based on assumptions, and involve known and unknown risks, uncertainties and other factors which may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by our projections. We may not actually achieve the plans, expectations or objectives contained in our projections, and the underlying assumptions may prove incorrect. Such deviations may be due to factors outside our control or currently unknown to us. For example, our actual revenues, market share, timing for achieving business milestones, expenses and profitability may differ materially from our expectations. Therefore, undue reliance should not be placed on any of our projections.

For example, in October 2021, we entered into the DG Fuels Agreement, which has the potential to generate up to $520 million in revenue across three projects, the first of which is expected to commence in mid-2022. The timing of the commencement of and payments under each project is subject to the execution of a sales agreement relating to such project and the revenue from each project will be dependent upon the agreed upon size of the project, and the timing of such project and the performance of DG Fuels. The receipt and timing of any revenue recognition and payments from the DG Fuels Agreement will be subject to the timing and execution of sales agreements and the performance by our counterparty under any such sales agreement for our energy storage systems. Any event or circumstance that delays or impairs our or our counterparty’s performance could materially adversely affect the amount or timing of revenue generated under the DG Fuels Agreement, and such revenue, if any, may be materially less than what we expect. There can be no assurance that sales agreements will be executed with respect to any of the projects, that any of such projects are completed, or that we will generate all $520 million of revenue, or any meaningful part thereof, under the DG Fuels Agreement or on the timeline we expect.

Certain estimates of market opportunity and forecasts of market growth may prove to be inaccurate.

This proxy statement/prospectus includes estimates of the addressable market for Energy Vault’s solutions, including our gravity-based energy storage systems and a digital platform that are in the early stages of developing, and the renewable energy and energy storage market in general. Market opportunity estimates and growth forecasts, whether obtained from third-party sources or development internally, are subject to significant uncertainty and are based on assumptions and estimates that may prove to be inaccurate. This is in part true at the present time due to the uncertain and rapidly changing projections of the severity, magnitude and duration of the current coronavirus, or COVID-19, pandemic. The estimates and forecasts in this proxy statement/prospectus relating to the size and expected growth of the target market, market demand and adoption, capacity to address this demand and pricing may also prove to be inaccurate. In particular, estimates regarding the current and projected market opportunity are difficult to predict, especially in light of the nascent stage of our industry. The estimated addressable market may not materialize for

TABLE OF CONTENTS

many years, and even if the markets meet the size estimates and growth forecasted in this proxy statement/prospectus, our business could fail to capture a meaningful share of the market or grow at similar rates.

Operational costs can be difficult to predict and may include costs from requirements related to the decommissioning of our systems.

We will rely heavily on complex machinery for our operations and our production will involve a significant degree of uncertainty and risk in terms of operational performance and costs. Our EVx systems will consist of large-scale machinery comprised of many components assembled on-site for our customers. The components of our EVx systems are likely to suffer unexpected malfunctions from time to time and will depend on repairs and spare parts to resume operations, which may not be available when needed. Unexpected malfunctions of our EVx systems or their constituent components may significantly affect the intended operational efficiency and performance. In addition, our EVx systems may need to be decommissioned from time to time, and the related costs could be significant given the expected size and complexity of our EVx systems. Operational performance and costs, including those related to project stoppage, can be difficult to predict and are often influenced by factors outside of our control, such as, but not limited to, scarcity of natural resources, environmental hazards and remediation, costs associated with construction, commissioning, testing or decommissioning of machines, labor disputes and strikes, difficulty or delays in obtaining governmental permits, damages or defects in electronic systems, industrial accidents, fire, seismic activity and natural disasters. Should operational risks materialize, it may result in the personal injury to or death of workers, the loss of production equipment, damage to manufacturing facilities, monetary losses, delays and unanticipated fluctuations in production, environmental damage, administrative fines, increased insurance costs and potential legal liabilities, all which could have a material adverse effect on our business, results of operations, cash flows, financial condition or prospects.

There is no assurance that non-binding letters of intent and other indications of interest will result in binding orders or sales. Customers may cancel or delay the non-binding letters of intent and other indications of interest in our sales pipeline. As a result, our operating results and cash flows may be materially lower than our expected results of operations.

Our success depends on our ability to generate revenue and operate profitably, which depends in part on our ability to identify target customers and convert such contacts into meaningful orders or expand on current customer relationships. As of this date, we do not have any definitive sales agreements in place although we have the DG Fuels Agreement (described below), the non-binding strategic partnership agreement with Sun Metals and certain detailed letters of intent that contemplate sales agreements. Potential customers may abandon their indications of interest, and non-binding letters of interest may be cancelled or delayed by a customer for any reason or its terms may be amended in an manner adverse to us in connection with negotiating a definitive sales agreement. For that reason, there can be no assurance that any current or future indications of interest or non-binding letters of intent will result in binding orders or sales. Furthermore, in light of our limited operating history, it is difficult for us to predict the rates at which the non-binding letters of interest in our pipeline will result in binding orders or sales. It is also difficult for us to predict how quickly we will be able to fill binding orders in the event that we obtain multiple orders. In addition, revenue is expected to be recognized in stages, and customers may in some cases delay actual cash payments regardless of progressive billings. Additionally, a customer’s ability to make payments could decline during the sales process, even to the point of insolvency or bankruptcy. As a result, our operating results and cash flow may be materially lower than we expect.

We have also entered into a commercial agreement with DG Fuels LLC, or the DG Fuels Agreement, which contemplates the execution of more definitive sales agreements for the proposed projects. The timing of projects and payments under the DG Fuels Agreement depends on the timing for signing the sales agreements, and potential delays in signing such agreements would result in reduced revenue and profitability under the sales agreements and would have an adverse effect on our business, results of operations and cash flow, which could be material.

Fuel prices, including volatility in the cost of diesel or natural gas or a prolonged period of low gasoline and natural gas costs, could decrease incentives to transition to renewable energy.

A portion of the current and expected demand for renewable energy results from concerns about volatility in the cost of gasoline and other petroleum-based fuel, the dependency of the United States on oil

TABLE OF CONTENTS

from unstable or hostile countries, government regulations and economic incentives promoting fuel efficiency and alternative forms of energy, as well as concerns about climate change resulting in part from the burning of fossil fuels. If the cost of gasoline and other petroleum-based fuel decreases significantly, the outlook for the long-term supply of oil to the United States improves, the government eliminates or modifies its regulations or economic incentives related to fuel efficiency and alternative forms of energy or there is a change in the perception in the cost-benefit analysis regarding the effects of burning fossil fuels on the environment, the demand for renewable energy, including energy storage products such as ours, could be reduced, and our business and revenue may be harmed.

Diesel, gasoline, natural gas and other petroleum-based fuel prices have historically been extremely volatile, particularly during the ongoing COVID-19 pandemic, and it is difficult to ascertain whether such volatility will continue to persist. Lower gasoline and natural gas costs over extended periods of time may lower the perception in government and the private sector that cheaper, more readily available energy alternatives, such as wind and solar, should be developed and produced. If gasoline or other petroleum-based fuel prices remain at deflated levels for extended periods of time, the demand for renewable energy may decrease notwithstanding incentives to transition to renewable energy, which would have an adverse effect on our business, prospects, financial condition and results of operations.

The economic benefit of our energy storage systems to our customers depends on the cost of electricity available from alternative sources, including local electric utility companies, which cost structure is subject to change.

The economic benefit of our energy storage systems to our customers includes, among other things, the benefit of reducing such customer’s payments to the local electric utility company. The rates at which electricity is available from a customer’s local electric utility company is subject to change and any changes in such rates may affect the relative benefits of our energy storage systems. Further, the local electric utility may impose “departing load,” “standby” or other charges on our customers in connection with their acquisition of our energy storage systems, the amounts of which are outside of our control and which may have a material impact on the economic benefit of our energy storage systems to our customers. Changes in the rates offered by local electric utilities and/or in the applicability or amounts of charges and other fees imposed by such utilities on customers acquiring our energy storage systems could adversely affect the demand for our energy storage systems.

Additionally, the electricity stored and released by our systems may not currently be cost-competitive in some geographic markets, and we may be unable to reduce our costs to a level at which our energy storage systems would be competitive in such markets. As such, unless the cost of electricity in these markets rises or we are able to generate demand for our energy storage systems based on benefits other than electricity cost savings, our potential for growth may be limited.

We operate in highly competitive energy industries and there is increasing competition. Many of our competitors and future competitors may have significantly more financial and other resources than we do and if we do not compete effectively, our competitive positioning and our operating results will be harmed.

The energy markets in which we intend to compete continue to evolve and are highly competitive. Many of our current and potential competitors are large entities at a more advanced stage in development and commercialization than we are and in some cases have significantly more financial and other resources, including larger numbers of managerial and technical personnel, to increase their market share. For example, several companies, such as ESS Inc., Eos Energy Enterprises Inc., Hydrostor Inc. and Primus Power, have each announced plans and demonstrated prototypes of products that would compete in the energy storage market, and battery vendors with whom we compete, such as Tesla, Inc., Fluence Energy, Inc., LG Chem, Ltd., Samsung Electronics Co., Ltd and Contemporary Amperex Technology Co. Limited, have already commercialized their respective energy storage solution products. Companies such as Tesla, Inc., Fluence Energy, Inc. and Wartsila Corporation are also developing their own energy management software. If our competitors continue to penetrate the renewable energy, energy storage and energy management software markets, we may experience a reduction in potential and actual market share. To date, we have focused our efforts on recruiting management and other employees, business planning, raising capital, selecting applicable third party technologies, establishing and attempting to establish partnerships

TABLE OF CONTENTS

with potential suppliers, customers and ecosystem partners, developing the EV1 and EVx systems and a digital platform, and general corporate development.

We expect competition in energy storage technology to intensify due to a regulatory push for lower-carbon energy sources, including intermittent sources such as wind and solar, continuing globalization, and consolidation in the energy industry. Developments in alternative technologies or improvements in energy storage technology made by competitors may materially adversely affect the sales, pricing and gross margins of our future EVx systems and any digital platform. If a competing process or technology is developed that has superior operational or price performance, our business would be harmed.

Furthermore, our gravity based energy storage technology also competes with other emerging or evolving technologies, such as thermal storage, chemical storage, hydrogen energy storage and carbon capture storage and sequestration. If we are unable to keep up with competitive developments, including if such technologies achieve lower prices or enjoy greater policy support than our technology, our competitive position and growth prospects may be harmed, which would adversely affect our business, prospects and financial condition.

Some of our current and potential competitors have longer operating histories and greater financial, technical, marketing and other resources than we do. These factors may allow our competitors to respond more quickly or efficiently than we can to new or emerging technologies. These competitors may engage in more extensive research and development efforts, undertake more far-reaching marketing campaigns and adopt more aggressive pricing policies, which may allow them to more effectively compete for new energy storage projects and energy management software customers.

We intend to continue committing significant resources to establish a competitive position. There is no assurance we will successfully identify the right partners or produce and bring our EVx systems and a digital platform to market on a timely basis, if at all, or that products and technologies developed by others will not render our EVx systems and any digital platform that we may develop obsolete or noncompetitive, any of which would adversely affect our business, prospects and operating results.

Our future growth depends upon our ability to maintain relationships with third parties, and the terms and enforceability of many of these relationships are not certain.

We expect to rely on engineering, procurement, construction, or EPC, firms as third-party general contractors to install energy storage systems at our customers’ sites. We are likely to work with a limited number of such EPC firms, which may impact our ability to facilitate customer installations as planned. Our work with contractors or their sub-contractors may have the effect of our being required to comply with additional rules (including rules unique to our customers), working conditions, site remediation and other union requirements, which can add costs and complexity to an installation project. In the future, the timeliness, thoroughness and quality of installation-related services performed by our general contractors and their sub-contractors may not meet our expectations and standards and it may be difficult to find and train third-party general contractors that meet our standards at a competitive cost.

In addition, a key component of our growth strategy is to develop or expand our relationships with third parties. For example, we are investing resources in establishing strategic relationships with market players across a variety of industries, including, large renewable project developers, commercial agents, environmental organizations and unions, to generate new customers or to grow our business. These programs may not roll out as quickly as planned or produce the results we anticipated. A significant portion of our business depends on attracting new partners and retaining existing partners, and such relationships may not be predicated on enforceable agreements or any agreements at all.

Any failure to offer high-quality technical support services may adversely affect our relationships with our customers and adversely affect our financial results.

Although we do not have definitive customer agreements in place, we expect that potential and actual customers will depend on our support organization to resolve any technical issues relating to the hardware and software included in our systems. In addition, our sales process is likely to depend highly on the quality of our hardware and software-enabled services, on our business reputation and on strong recommendations

TABLE OF CONTENTS

from our existing customers. Any failure to maintain high-quality and highly-responsive technical support, or a market perception that we do not maintain high-quality and highly-responsive support, could adversely affect our reputation, our ability to sell our products to existing and prospective customers, and our business, financial condition and results of operations.

We intend to offer technical support services alongside our systems. We intend to have a designated team of engineers to support our customers, and they may be unable to respond quickly enough to accommodate short-term increases in demand for support services, particularly as we increase the size of our customer base. We also may be unable to modify the format of our support services to compete with changes in support services provided by competitors. At our current stage, it is difficult to predict demand for technical support services and if demand were to increase significantly beyond our expectations, we may be unable to provide satisfactory support services to our customers. Additionally, increased demand for these services, without corresponding revenue, could increase costs and adversely affect our business, financial condition and results of operations.

Our systems rely on interconnections to distribution and transmission facilities that are owned and operated by third parties, and as a result, are exposed to interconnection and transmission facility development and curtailment risks.

Moreover, our EVx systems and EVRCs are intended to be interconnected with electric distribution and transmission facilities owned and operated by regulated utilities, and independent system operators, necessary to deliver the electricity that our energy storage systems produce. A failure or delay in the operation or development of these distribution or transmission facilities could result in a loss of revenues or breach of a contract because such a failure or delay could limit the amount of renewable electricity that our energy storage systems deliver or delay the completion of our customers’ construction projects. In addition, certain of our energy storage systems�� generation may be curtailed without compensation due to distribution and transmission limitations, reducing our revenues and impairing our ability to capitalize fully on a particular customer project’s potential. Such a failure or curtailment at levels above our expectations could adversely affect our business.

Incorrect estimates or assumptions by management in connection with the preparation of our consolidated financial statements could adversely affect our reported assets, liabilities, income, revenue or expenses.

The preparation of our consolidated financial statements requires management to make critical accounting estimates and assumptions that affect the reported amounts of assets, liabilities, income, revenues or expenses during the reporting periods. Incorrect estimates and assumptions by management could adversely affect our reported amounts of assets, liabilities, income, revenues and expenses during the reporting periods. If we make incorrect assumptions or estimates, our reported financial results may be over- or understated, which could materially and adversely affect our business, financial condition and results of operations

Unanticipated changes in our income tax rates or exposure to additional tax liabilities may affect future financial results.

Energy Vault is, and the Combined Company will be, a U.S. corporation and thus subject to U.S. corporate income tax on its worldwide operations. Certain of our operations and potential customers are located in the United States, and as a result, the Combined Company is subject to various U.S. federal, state and local taxes. New U.S. laws and policy relating to taxes may have an adverse effect on Combined Company’s business and future profitability. Further, existing U.S. tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to the Combined Company.

For example, on December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”), was signed into law making significant changes to the Code, and certain provisions of the Tax Act may adversely affect the Combined Company. In particular, sweeping changes were made to the U.S. taxation of foreign operations. Changes include, but are not limited to, a reduction to the corporate income tax rate from a top marginal rate of 35% to a flat rate of 21%, the limitation of the tax deduction for net interest expense to 30% of adjusted taxable income (except for certain small businesses), the limitation of the deduction for net operating losses from taxable years beginning after December 31, 2017 to 80% of current year taxable

income and the elimination of net operating loss carrybacks generated in taxable years ending after December 31, 2017 (though any such net operating losses may be carried forward indefinitely), adoption of elements of a territorial tax system, assessment of a repatriation tax or “toll-charge” on undistributed earnings and profits of U.S.-owned foreign corporations, and introduction of certain anti-base erosion provisions, including a new minimum tax on global intangible low-taxed income and base erosion and anti-abuse tax. Additionally, on March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was signed into law, and among other things, the CARES Act suspends the 80% limitation on the deduction for net operating losses in taxable years beginning before January 1, 2021, permits a 5-year carryback of net operating losses arising in taxable years beginning after December 31, 2017 and before January 1, 2021, and generally caps the limitation on the deduction for net interest expense at 50% of adjusted taxable income for taxable years beginning in 2019 and 2020.

Further, President Joe Biden has set forth several tax proposals that would, if enacted, make significant changes to U.S. tax laws (including provisions enacted pursuant to the Tax Act). Such proposals include, but are not limited to an increase in the U.S. income tax rate applicable to corporations from 21% to 28%, (ii) an increase in the maximum U.S. federal income tax rate applicable to individuals and (iii) an increase in the U.S. federal income tax rate for long term capital gain for certain taxpayers with income in excess of a threshold amount. Congress may consider, and could include, some or all of these proposals in connection with tax reform to be undertaken by the current administration. It is unclear whether these or similar changes will be enacted and, if enacted, how soon any such changes could take effect. The passage of any legislation as a result of these proposals and other similar changes in U.S. federal income tax laws could adversely affect our business and future profitability. Investors are urged to consult with their legal and tax advisors with respect to any such legislation and the potential tax consequences of holding our securities.

Additionally, although we currently primarily operate in the U.S. and Switzerland, we will seek to expand our business internationally to other markets including additional EU countries, the U.K., Saudi Arabia, Australia, Brazil. Any international expansion of our business could subject our business to tax risks associated with international operations. For example, tax compliance in various jurisdictions, some of which may have potentially conflicting tax laws, and all of which are subject to change, potentially with retroactive effect, could result in materially higher cash tax liabilities for our business. The tax laws in jurisdictions where we conduct business and applicable U.S. tax laws as they relate to international operations may not act together in a coordinated fashion, which could also result in material incremental taxes for our business. Moreover, an expansion of our business internationally also creates risks that our business could have a taxable presence in jurisdictions where we are not filing tax returns. Taxing authorities have gotten increasingly aggressive regarding asserting that companies have a taxable presence in jurisdictions, and our business could face these risks in connection with the internal expansion of our business.

Cyber-attacks and other security breaches could have an adverse effect on our business, harm our reputation and expose us to liability.

Computer malware, viruses, physical or electronic break-ins and similar disruptions could lead to interruption and delays in our services and operations and loss, misuse or theft of data. Computer malware, viruses, ransomware, hacking and phishing attacks against online networks have become more prevalent and may occur on our systems in the future. Any attempts by cyber attackers to disrupt our services or systems, if successful, could harm our business, introduce liability to data subjects, result in the misappropriation of funds, be expensive to remedy and damage our reputation or brand. Insurance may not be sufficient to cover significant expenses and losses related to cyber-attacks (such as the May 2021 cyber-attacks with Colonial Pipeline). Efforts to prevent cyber attackers from entering computer systems are expensive to implement, and we may not be able to cause the implementation or enforcement of such preventions with respect to our third-party vendors. Though it is difficult to determine what, if any, harm may directly result from any specific interruption or attack, any failure to maintain performance, reliability, security and availability of systems and technical infrastructure may, in addition to other losses, harm our reputation, brand and ability to attract customers.

We may in the future experience, service disruptions, outages and other performance problems due to a variety of factors, including infrastructure changes, third-party service providers, human or software errors and capacity constraints.

TABLE OF CONTENTS

We are putting processes and procedures in place designed to enable Energy Vault to quickly recover from a disaster or catastrophe and continue business operations and have tested this capability under controlled circumstances. However, there are several factors ranging from human error to data corruption that could materially impact the efficacy of such processes and procedures, including by lengthening the time services are partially or fully unavailable to customers and users. It may be difficult or impossible to perform some or all recovery steps and continue normal business operations due to the nature of a particular disaster or catastrophe, especially during peak periods, which could cause additional reputational damages, or loss of revenues, any of which could adversely affect our business and financial results.

In the future our EVx systems, EVRCs and any digital platform that we develop may experience outages and other performance problems due to a variety of factors, including infrastructure changes, third-party service providers, human or software errors and capacity constraints. We may also face changes in our EVx system and EVRCs, which could lead to damages, accidents and or system disruptions. We may in the future experience blackmail for our EVx software or any software underpinning any digital platform that we may develop, which could shut down operation of our systems, those of our potential customers, or cause other damage to such systems.

Any significant disruption in in our computer systems, some of which will be hosted by third-party providers, could damage our reputation and result in negative publicity, which would harm our business and results of operations.

Although the computer systems for our EVx systems and EVRCs will strictly be on-premise, we will use third-party web services for administrative purposes and as a backup for our customers in case there is an on-site system failure. Interruptions, whether due to system failures, human errors, computer viruses, physical or electronic break-ins, denial-of-service attacks, and capacity limitations, could delay or inhibit our operations. Problems with the reliability of our systems could prevent us from earning revenue and could harm our reputation. Damage to our reputation, any resulting loss of user confidence and the cost of remedying these problems could negatively affect our business, results of operations, financial condition, and prospects.

We have service agreements with data center providers. Problems with our third-party service providers or with their network providers or with the systems allocating capacity among their users, including us, could adversely affect our ability to serve our customers or perform our administrative work. Our third-party service providers could decide to close their facilities without adequate notice. Any financial difficulties, such as bankruptcy or reorganization, faced by our third-party service providers or any of the service providers with whom they contract may have negative effects on our business, the nature and extent of which are difficult to predict. If our third-party service providers are unable to keep up with our needs for capacity, this could have an adverse effect on our business. In the event that our agreements with any of our third-party service providers is terminated, or we add additional cloud infrastructure service providers, we may experience significant costs or downtime in connection with the transfer to, or the addition of, new cloud infrastructure service providers. Any of the above circumstances or events may harm our reputation and brand or increase our costs, any of which could adversely affect our business, financial condition, and results of operations.

Changes in business, economic, or political conditions, including overall changes in demand, are beyond our control and could impact our business, resulting in lower revenues and other adverse effects to our results of operations.

In recent years, the United States and other significant markets have experienced cyclical downturns and worldwide economic conditions remain uncertain. This was especially the case in 2020 as a result of the COVID-19 pandemic. In addition, economic uncertainty and associated macroeconomic conditions make it extremely difficult for our partners, suppliers, and us to accurately forecast and plan future business activities and could cause our customers to slow spending on our offerings.

A significant downturn in the domestic or global economy may cause our customers to pause, delay, or cancel spending on our offerings or seek to lower their costs by exploring alternatives. To the extent purchases of our offerings are perceived by customers and potential customers as discretionary, our revenue may be

TABLE OF CONTENTS

disproportionately affected by delays or reductions in energy storage spending. Also, competitors may respond to challenging market conditions by lowering prices and attempting to lure away our customers.

Similarly, our business depends on the overall business and global or regional political conditions, which are beyond our control.

We cannot predict the timing, strength, or duration of any economic slowdown or any subsequent recovery generally, or any industry in particular or how global business and political conditions may change. To the extent that general business, economic or political conditions, including overall changes in demand for our products, decline, our business, financial condition and results of operations, including revenues, could be materially adversely affected.

Our facilities or systems could be damaged or adversely affected as a result of disasters or other unpredictable events. Any prolonged disruption in operations would adversely affect our business, prospects, financial condition and operating results.

Our facilities or systems could be adversely affected by events outside of our control, such as natural catastrophic events, geographical instability, wars, and other calamities. For example, an installed EVx system or EVRC could be severely damaged by fire or earthquake, and the severity of such event may be exacerbated if we, as opposed to our customer, own such product. We cannot assure you that, collectively, our process and procedures to recover from a disaster or catastrophe will be adequate to protect us from the effects of fire, floods, typhoons, earthquakes, power loss, telecommunications failures, break-ins, war, riots, terrorist attacks, pandemics (including the COVID-19 pandemic) or similar events. Any of the foregoing events may give rise to interruptions, breakdowns, system failures, technology platform failures or internet failures, which could cause the loss or corruption of data or malfunctions of software or hardware as well as adversely affect our ability to produce our EVx systems. In addition, to the extent such events precipitate prolonged disruptions in our operations, our business, prospects, financial condition and operating results may be materially adversely affected.

Our financial condition and results of operations as well as those of potential customers have been, and may continue to be for the foreseeable future, adversely affected by the ongoing COVID-19 pandemic, which has caused a material adverse effect on the level of economic activity around the world, including in the markets we serve.

On March 12, 2020, the World Health Organization declared COVID-19 to be a pandemic. In an effort to contain and mitigate the spread of COVID-19, many countries, including the United States, imposed unprecedented restrictions on travel and business operations, and there have been business closures and a substantial reduction in economic activity in countries that have had significant outbreaks of COVID-19, including in the markets we serve. In certain cases, these restrictions have been lifted and then reimposed in part or in full.

Our operations and performance depend significantly on global and regional economic conditions, and the outbreak of COVID-19, together with the measures taken in response to the COVID-19 pandemic, has had a significant negative effect on global and regional economies. For example, Energy Vault contracted a third party to build the crane that is part of its commercial demonstration unit in Switzerland. The third party failed to deliver critical equipment, and certain errors in construction became apparent. We therefore terminated the relationship, and the construction of the crane in Switzerland was more expensive and took longer than expected. We believe that the effects COVID-19 exacerbated the additional costs and time required to complete this crane and that the completion of the crane was delayed by at least six months.

We are continuing to conduct business with substantial restrictions, such as remote working and less employee travel, among other modifications. We also put into place health and safety policies. As a cash conservation policy, we also instituted salary reductions across our entire employee base, including members of our senior management team.

The global outbreak of COVID-19 continues to rapidly evolve, especially as COVID-19 cases and corresponding government actions responsive to COVID-19 continue to increase in certain parts of the world. The extent to which COVID-19 may impact our business will depend on future developments, which

TABLE OF CONTENTS

are highly uncertain and cannot be predicted with confidence, including the duration of the pandemic, travel restrictions, social distancing requirements or other governmental or business disruptions, global unemployment rates, the development and distribution of vaccines, the emergence of COVID-19 variants, and the effectiveness of actions taken in the United States and other countries to prevent, contain, and treat the disease. See the section titled “Energy Vault Management’s Discussion and Analysis of Financial Condition and Results of Operations — Key Factors and Trends Affecting our Business — COVID-19” for a further discussion of the impact of the COVID-19 pandemic on our business.

Following the consummation of the Business Combination, we expect to incur significant increased expenses and administrative burdens as a public company, which could negatively impact our business, financial condition and results of operations.

We will face increased legal, accounting, administrative and other costs and expenses as a public company that we did not incur as a private company. We expect such costs and increases to be increased further after we are no longer an emerging growth company. The Sarbanes-Oxley Act, including the requirements of Section 404, as well as rules and regulations subsequently implemented by the SEC, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and the rules and regulations promulgated and to be promulgated thereunder, the Public Company Accounting Oversight Board and the securities exchanges, impose additional reporting and other obligations on public companies. Compliance with public company requirements will increase costs and make certain activities more time-consuming. A number of those requirements require us to carry out activities we have not done previously. In addition, expenses associated with SEC reporting requirements will be incurred. Furthermore, if any issues in complying with those requirements are identified (for example, if the auditors identify a significant deficiency or material weaknesses in the internal control over financial reporting), we could incur additional costs to rectify those issues, and the existence of those issues could adversely affect our reputation or investor perceptions.

In addition, we will maintain director and officer liability insurance, which has substantial additional premiums. Advocacy efforts by stockholders and third parties may also prompt additional changes in governance and reporting requirements, which could further increase costs.

As a private company, we have not endeavored to establish and maintain public company-quality internal control over financial reporting. If we fail to establish and maintain proper and effective internal control over financial reporting as a public company, our ability to produce accurate and timely financial statements could be impaired, investors may lose confidence in our financial reporting and the trading price of our common stock may decline.

Pursuant to Section 404 of the Sarbanes-Oxley Act, following completion of the business combination, the report by management on internal control over financial reporting will be on our financial reporting and internal controls (as accounting acquirer). As a private company, we have not previously been required to conduct an internal control evaluation and assessment. The rules governing the standards that must be met for management to assess internal control over financial reporting are complex and require significant documentation, testing and possible remediation. To comply with the Sarbanes-Oxley Act, the requirements of being a reporting company under the Exchange Act and any complex accounting rules in the future, the Combined Company, may need to upgrade our legacy information technology systems; implement additional financial and management controls, reporting systems and procedures; and hire additional accounting and finance staff.

If we are unable to hire the additional accounting and finance staff necessary to comply with these requirements, it may need to retain additional outside consultants. we or, if required, our independent registered public accounting firm, are unable to conclude that our internal control over financial reporting is effective, investors may lose confidence in our financial reporting, which could negatively impact the market price of Combined Company Common Stock.

Risks Related to Government Regulation

Our business may depend on the continued availability of rebates, tax credits and other financial incentives. The reduction, modification, or elimination of government economic incentives could cause our revenue to decline and harm our financial results.

The U.S. federal government and some state and local governments provide incentives to end users in the form of rebates, tax credits, and other financial incentives, such as system performance payments and payments for renewable energy credits associated with renewable energy generation. For example, current U.S. law enables any utilization of the federal 30% Investment Tax Credit (ITC) in case a storage project is built in combination with a solar facility. In addition, some countries outside the United States also provide incentives to end users. Our EVx systems may qualify for tax exemptions, incentives, or other customer incentives in certain jurisdictions. Some states have utility procurement programs and/or renewable portfolio standards for which our technology may be eligible. Our business may rely on these governmental rebates, tax credits, and other financial incentives to significantly lower the effective price of our EVx systems to our customers. However, these incentives may expire on a particular date, end when the allocated funding is exhausted, or be reduced or terminated as a matter of regulatory or legislative policy.

Changes in the availability of rebates, tax credits, and other financial programs and incentives could reduce demand for our EVx systems, impair sales financing, and adversely impact our business results. The continuation of these programs and incentives depends upon political support which to date has been bipartisan and durable. Nevertheless, a set of political activists may seek to expand these programs while may seek to eliminate them.

We could be liable for environmental damage resulting from our operations, which could impact our reputation, our business, and our operating results.

We are subject to federal, state, and local environmental laws and regulations as well as environmental laws in those foreign jurisdictions in which we operate. Environmental laws and regulations can be complex and may often change. These laws can give rise to liability for administrative oversight costs, cleanup costs, property damage, bodily injury, fines, and penalties. Capital and operating expenses needed to comply with environmental laws and regulations can be significant, and violations may result in substantial fines and penalties or third-party damages. In addition, maintaining compliance with applicable environmental laws requires significant time and management resources and could cause delays in our ability to build out, equip and operate our facilities as well as service our fleet, which would adversely impact our business, our prospects, our financial condition, and our operating results. In addition, environmental laws and regulations such as the Comprehensive Environmental Response, Compensation and Liability Act in the United States impose liability on several grounds including for the investigation and cleanup of contaminated soil and ground water, for building contamination, for impacts to human health and for damages to natural resources. If contamination is discovered in the future at properties formerly owned or operated by us or currently owned or operated by us, or properties to which hazardous substances were sent by us, it could result in our liability under environmental laws and regulations. Many of our customers who have agreed to purchase our EVx systems and EVRCs have high sustainability standards, and any environmental noncompliance by us could harm our reputation and impact a current or potential customer’s buying decision. Additionally, in many cases we contractually commit to performing all necessary installation work on a fixed-price basis, and unanticipated costs associated with environmental remediation and/or compliance expenses may cause the cost of performing such work to exceed our revenue. The costs of complying with environmental laws, regulations, and customer requirements, and any claims concerning noncompliance or liability with respect to contamination in the future, could have a material adverse effect on our financial condition or our operating results.

Action by governmental authorities and local residents to restrict construction or use of our systems in their localities could substantially harm our business and financial results.

In the United States and elsewhere, the construction and implementation of our systems is subject to local laws, regulations, rules and agreements regarding zoning, permitting and land use. From time to time, various interest groups lobby for or against amendments to such rules that would allow potential customers to

TABLE OF CONTENTS

implement our systems in locations desirable to them. In certain cases, potential customers may need to petition for changes or waivers to such rules in order to be allowed to implement our systems. In all cases, governmental authorities and local residents may oppose the implementation of our systems by our potential customers, which could cause delays, potential damage to our relationships with customers and increased costs to us and our customers. If laws, regulations, rules, or agreements significantly restrict or discourage our potential customers in certain jurisdictions from purchasing and implementing our systems, it would have a material adverse effect on our business, results of operations, and financial condition. In addition, there can be no assurance that future macroeconomic pressures and public policy concerns could continue to lead to new laws and regulations, or interpretations of existing laws and regulations, that would limit our future customers’ use of our systems.

Changes in regulatory enforcement policies and priorities may negatively impact the management of our business, results of operations, and ability to compete.

Energy and environmental regulation is constantly changing, and policy or changes in enforcement of existing laws or regulations applicable to our business, or reexamination of current practices, could adversely impact our profitability, limit our ability to continue existing or pursue new business activities, require us to change certain of our business practices, affect retention of key personnel, or expose us to additional costs (including increased compliance costs and/or customer remediation). These changes also may require us to invest significant resources, and devote significant management attention, to make any necessary changes and could adversely affect our business.

We are subject to licensing and operational requirements that result in substantial compliance costs, and our business would be adversely affected if our licenses are impaired.

Our business is subject to numerous federal and state laws and regulations. In particular, our business is subject to oversight and regulation under local ordinances, building, zoning and fire codes, environmental protection regulation, utility interconnection requirements, and other rules and regulations. Such licenses often require us to operate in ways that incur substantial compliance costs.

To date, we have not deployed any EVx systems. We intend to obtain and hold the certificates and/or licenses needed for our near-term plans to install EVx systems. Although we believe that obtaining and renewing such certificates and/or licenses will be routine, we cannot assure you that any of them will be renewed in a timely manner. Our failure to hold a given license or certificate would impair our ability to perform our obligations under our customer contracts. The number of laws affecting our business continues to grow. If our licenses or certificates were impaired, whether by expiration, nonrenewal or modification or termination, our business would be adversely impaired.

We can give no assurances that we will properly and timely comply with all laws and regulations that may affect us. If we fail to comply with these laws and regulations, we may be subject to legal penalties, which would adversely affect our business, prospects, and results of operations.

Litigation, regulatory actions and compliance issues could subject us to significant fines, penalties, judgments, remediation costs, negative publicity and requirements resulting in increased expenses.

We have been and continue to be involved in legal proceedings, administrative proceedings, claims and other litigation that arise in the ordinary course of business. In addition, since our energy storage system is a new type of product in a nascent market, we may in the future need to seek the amendment of existing regulations or, in some cases, the creation of new regulations, in order to operate our business in some jurisdictions. Such regulatory processes may require public hearings concerning our business, which could expose us to subsequent litigation.

Unfavorable outcomes or developments relating to proceedings to which we are a party or transactions involving our products, such as judgments for monetary damages, injunctions, or denial or revocation of permits, could have a material adverse effect on our business, financial condition, and results of operations. To the extent such proceedings also generate negative publicity, our reputation and business could also be adversely affected. In addition, handling compliance issues and the settlement of claims could adversely affect our financial condition and results of operations.

TABLE OF CONTENTS

Laws, regulations and rules relating to privacy, information security, and data protection could increase our costs and adversely affect our business opportunities. In addition, the ongoing costs of complying with such laws, regulations and rules could be significant.

We are subject to various laws regarding privacy, information security and data protection. In particular, our handling of data relating to individuals is subject to a variety of laws and regulations relating to privacy, data protection, and information security, and it may become subject to additional obligations, including contractual obligations, relating to our maintenance and other processing of this data. For example, the European Union’s General Data Protection Regulation, or GDPR, imposes stringent data protection requirements and provides for significant penalties for noncompliance. Laws, regulations, and other actual and potential obligations relating to privacy, data protection, and data security are evolving rapidly, and the regulatory landscape regarding privacy, data protection, and data security is likely to remain uncertain for the foreseeable future. We expect to be subject to new laws and regulations, or new interpretations of laws and regulations, in the future in various jurisdictions. These laws, regulations, and other obligations, and changes in their interpretation, could require us to modify our operations and practices, restrict our activities, and increase our costs in the future, and it is possible that these laws, regulations, and other obligations may be inconsistent with one another or be interpreted or asserted to be inconsistent with our business or practices. Any inability to adequately address privacy and security concerns or comply with applicable privacy and information security laws, rules and regulations could have an adverse effect on our business, prospects, results of operations, financial position and reputation.

Risks Related to Intellectual Property

We may be unable to protect, defend, maintain or enforce intellectual property on which our business depends, including as against existing or future competitors. Failure to protect defend, maintain and enforce that intellectual property could result in our competitors offering similar products, potentially adversely affecting our growth and success.

Although we have taken many protective measures to protect our trade secrets, including agreements, limited access, segregation of knowledge, password protections and other measures, policing unauthorized use of proprietary technology can be difficult and expensive. For example, certain of our engineers reside in California and it is not legally permissible to prevent them from working for a competitor, if and when one should exist. Also, litigation may be necessary to enforce our intellectual property rights, protect our trade secrets, or determine the validity and scope of the proprietary rights of others. Such litigation may result in our intellectual property rights being challenged, limited in scope, or declared invalid or unenforceable. We cannot be certain that the outcome of any litigation will be in our favor, and an adverse determination in any such litigation could impair our intellectual property rights and may harm our business, prospects and reputation.

We rely primarily on patent, copyright, trade secret and trademark laws, and non-disclosure, confidentiality, and other types of contractual restrictions to establish, maintain, and enforce our intellectual property and proprietary rights. However, our rights under these laws and agreements afford us only limited protection and the actions we take to establish, maintain, and enforce our intellectual property rights may not be adequate. For example, our trade secrets and other confidential information could be disclosed in an unauthorized manner to third parties, our owned or licensed intellectual property rights could be challenged, invalidated, circumvented, infringed, or misappropriated or our intellectual property rights may not be sufficient to provide us with a competitive advantage, any of which could have a material adverse effect on our business, financial condition or operating results. In addition, the laws of some countries do not protect proprietary rights as fully as do the laws of the United States. As a result, we may not be able to protect our proprietary rights adequately abroad.

Our patents and, patent applications if issued, may not provide adequate protection to create a barrier to entry. The provisional and non-provisional patent applications that we own may not issue as patents or provide adequate protection to create a barrier to entry, which may hinder our ability to prevent competitors from selling products similar to ours.

We cannot be certain that our pending patent applications will result in issued patents or that any of our issued patents will afford protection against a competitor. The status of patents involves complex legal

TABLE OF CONTENTS

and factual questions, and the breadth of claims allowed is uncertain. As a result, we cannot be certain that the patent applications that we file will result in patents being issued or that our patents and any patents that may be issued to us in the future will afford protection against competitors with similar technology. In addition, patent applications filed in foreign countries are subject to laws, rules, and procedures that differ from those of the United States, and thus we cannot be certain that foreign patent applications related to issued U.S. patents will be issued in other regions. Furthermore, even if these patent applications are accepted and the associated patents issued, some foreign countries provide significantly less effective patent enforcement than in the United States.

In addition, patents issued to us may be infringed upon or designed around by others and others may obtain patents that we need to license or design around, either of which would increase costs and may adversely affect our business, our prospects, and our operating results.

We may be subject to third-party claims of infringement, misappropriation or other violation of intellectual property rights, or other claims challenging our agreements related to intellectual property, which may be time-consuming and costly to defend, and could result in substantial liability.

Companies, organizations, or individuals, including our competitors, may hold or obtain patents, trademarks, or other proprietary rights that they may in the future believe are infringed by our products or services. These companies holding patents or other intellectual property rights allegedly relating to our technologies could, in the future, make claims or bring suits alleging infringement, misappropriation, or other violations of such rights, or otherwise assert their rights and by seeking royalties or injunctions. If a claim is successfully brought in the future and we or our products are determined to have infringed, misappropriated, or otherwise violated a third party’s intellectual property rights, we may be required to do one or more of the following:

•

cease selling or using our products that incorporate the challenged intellectual property;

•

pay substantial damages (including treble damages and attorneys’ fees if our infringement is determined to be willful);

•

obtain a license from the holder of the intellectual property right, which may not be available on reasonable terms or at all; or

•

redesign our products or means of production, which may not be possible or cost-effective.

Any of the foregoing could adversely affect our business, prospects, operating results, and financial condition. In addition, any litigation or claims, whether or not valid, could harm our reputation, result in substantial costs and divert resources and management attention.

We also license technology from third parties and incorporate components supplied by third parties into our products. We may in the future face claims that our use of such technology or components infringes or otherwise violates the rights of others, which would subject us to the risks described above. We may in some cases seek indemnification from our licensors or suppliers under our contracts with them, but our rights to indemnification or our suppliers’ resources may be unavailable or insufficient to cover our costs and losses.

Risks Related to the Combined Company

Unless the context otherwise requires, all references to “we,” “us,” or “our” in this subsection titled “Risks Related to the Combined Company” refer to the Combined Company.

Concentration of ownership among the Combined Company’s executive officers, directors and their affiliates may prevent new investors from influencing significant corporate decisions.

Upon completion of the Business Combination, the initial stockholders of Energy Vault will beneficially own, directly or indirectly, assuming no Earn Out Shares are issued:

•

approximately 68.0% of the Combined Company’s outstanding common stock and the executive officers, directors of Energy Vault and their affiliates as a group will beneficially own approximately 33.6% of the Combined Company’s outstanding common stock, assuming no redemption of the Public Shares; or

TABLE OF CONTENTS

•

approximately 83.8% of the Combined Company’s outstanding common stock and the executive officers, directors of Energy Vault and their affiliates as a group will beneficially own approximately 41.8% of the Combined Company’s outstanding common stock, assuming that all 26,838,263 Public Shares (which represents the maximum number of shares which may be redeemed) are redeemed.

As a result, these stockholders will be able to exercise a significant level of control over all matters requiring stockholder approval, including the election of directors, appointment and removal of officers, any amendment of the amended and restated certificate of incorporation and approval of mergers and other business combination transactions requiring stockholder approval, including proposed transactions that would result in the Combined Company Stockholders receiving a premium price for their shares and other significant corporate transactions. This control could have the effect of delaying or preventing a change of control or changes in management and will make the approval of certain transactions difficult or impossible without the support of these stockholders.

There can be no assurance that the Combined Company’s common stock or warrants will be approved for listing on the NYSE or that the Combined Company will be able to comply with the continued listing standards of the NYSE.

In connection with the closing of the Business Combination, we intend to list the Combined Company’s common stock and warrants on the NYSE under the symbols “NRGV” and “NRGV WS,” respectively. The Combined Company’s continued eligibility for listing may depend on the number of our shares that are redeemed. If, after the Business Combination, NYSE delists the Combined Company’s shares from trading on its exchange for failure to meet the listing standards, the Combined Company and its stockholders could face significant negative consequences including:

•

limited availability of market quotations for the Combined Company’s securities;

•

a determination that the Combined Company’s common stock is a “penny stock” which will require brokers trading in the Combined Company’s common stock to adhere to more stringent rules, possibly resulting in a reduced level of trading activity in the secondary trading market for shares of the Combined Company’s common stock;

•

a limited amount of analyst coverage; and

•

a decreased ability to issue additional securities or obtain additional financing in the future.

If the Business Combination’s benefits do not meet the expectations of investors or securities analysts, the market price of Novus’s securities or, following the Closing, the Combined Company’s securities, may decline.

If the perceived benefits of the Business Combination do not meet the expectations of investors or securities analysts, the market price of Novus’s securities prior to the Closing may decline. The market values of the Combined Company’s securities at the time of the Business Combination may vary significantly from their prices on the date the Business Combination Agreement was executed, the date of this proxy statement/prospectus, or the date on which Novus’s stockholders vote on the Business Combination.

In addition, following the Business Combination, fluctuations in the price of the Combined Company’s securities could contribute to the loss of all or part of your investment. Prior to the Business Combination, there has not been a public market for Energy Vault’s securities. Accordingly, the valuation ascribed to Energy Vault may not be indicative of the price that will prevail in the trading market following the Business Combination. If an active market for the Combined Company’s securities develops and continues, the trading price of the Combined Company’s securities following the Business Combination could be volatile and subject to wide fluctuations in response to various factors, some of which are beyond the Combined Company’s control. Any of the factors listed below could have a negative impact on your investment in the Combined Company’s securities and the Combined Company’s securities may trade at prices significantly below the price you paid for them. In such circumstances, the trading price of the Combined Company’s securities may not recover and may experience a further decline.

Factors affecting the trading price of the Combined Company’s securities may include:

TABLE OF CONTENTS

•

actual or anticipated fluctuations in the Combined Company’s quarterly financial results or the quarterly financial results of companies perceived to be similar to it;

•

changes in the market’s expectations about the Combined Company’s operating results;

•

success of competitors;

•

failure to attract analyst coverage for the Combined Company’s stock or one or more analysts ceases coverage of the Combined Company or fails to publish reports on the Combined Company regularly;

•

the Combined Company’s operating results failing to meet the expectation of securities analysts or investors in a particular period;

•

changes in financial estimates and recommendations by securities analysts concerning the Combined Company or the transportation industry in general;

•

operating and share price performance of other companies that investors deem comparable to the Combined Company;

•

the Combined Company’s ability to market new and enhanced products and technologies on a timely basis;

•

changes in laws and regulations affecting the Combined Company’s business;

•

the Combined Company’s ability to meet compliance requirements;

•

commencement of, or involvement in, litigation involving the Combined Company;

•

changes in the Combined Company’s capital structure, such as future issuances of securities or the incurrence of additional debt;

•

the volume of the Combined Company’s shares of common stock available for public sale;

•

any major change in the Combined Company’s board of directors or management;

•

sales of substantial amounts of the Combined Company’s shares of common stock by the Combined Company’s directors, executive officers or significant stockholders or the perception that such sales could occur; and

•

general economic and political conditions such as recessions, interest rates, fuel prices, international currency fluctuations and acts of war or terrorism.

Broad market and industry factors may materially harm the market price of the Combined Company’s securities irrespective of the Combined Company’s operating performance. The stock market in general, and NYSE in particular, have experienced price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the particular companies affected. The trading prices and valuations of these stocks, and of the Combined Company’s securities, may not be predictable. A loss of investor confidence in the market for retail stocks or the stocks of other companies which investors perceive to be similar to the Combined Company could depress the Combined Company’s share price regardless of the Combined Company’s business, prospects, financial conditions or results of operations. A decline in the market price of the Combined Company’s securities also could adversely affect the Combined Company’s ability to issue additional securities and the Combined Company’s ability to obtain additional financing in the future.

The SEC has recently issued guidance on the accounting treatment of warrants. Novus has accounted for its outstanding warrants as a warrant liability and will be required to determine the value warrant liability quarterly, which could have a material impact on Novus’s financial position and operating results.

In the Staff Statement issued by the Staff of the SEC on April 12, 2021, the Staff expressed its view that certain terms and conditions common to SPAC warrants may require the Warrants to be classified as liabilities on the SPAC’s balance sheet as opposed to equity. Following the issuance of such Staff Statement, on May 20, 2021, Novus concluded that it was appropriate to restate its previously issued audited balance sheet as of February 8, 2021. A summary of the effect of the restatement on the audited balance sheet was

TABLE OF CONTENTS

included in the notes to the financial statements filed as part of Novus’s Quarterly Report on Form 10-Q for the three months ended March 31, 2021. The restated balance sheet summary reflects the change in accounting treatment of the Novus’s Public Warrants and Private Warrants issued in connection with its initial public offering in February 2021 (which were previously recorded as a component of equity on the balance sheet) as liabilities measured at fair value upon issuance, with subsequent changes in fair value reported in the statement of operations for subsequent reporting periods. Under this accounting treatment, Novus is required to measure the fair value of the Warrants on a quarterly basis as well as re-evaluate the treatment of the Warrants and recognize changes in the fair value from the prior period in Novus’s operating results for the current period. The impact of changes in fair value on earnings, which may be material, may have an adverse effect on the market price of the Combined Company’s securities.

Following completion of the business combination, the Combined Company will be required to recognize the changes in the fair value of the Warrants from the prior period, if any, in its operating results for the current period, which could have a material impact on the Combined Company’s financial position and operating results.

We may face litigation and other risks as a result of the material weaknesses in our internal control over financial reporting and may report additional material weaknesses in our internal control over financial reporting in the future.

On May 20, 2021, Novus concluded that it was appropriate to restate its previously issued audited balance sheet as of February 8, 2021, and as part of such process, Novus identified a material weakness in its internal control over financial reporting. As the accounting acquirer in the business combination, we will inherit this material weakness and the Warrants. We cannot assure as to when this material weakness will be remediated. Additionally, on November 14, 2021, Novus concluded that it was appropriate to restate its previously issued unaudited financial statements for the periods ended March 31, 2021 and June 30, 2021, and as part of such process, Novus identified an additional material weakness in its internal control over financial reporting resulting from the improper valuation of its Class A common stock subject to possible redemption. As the accounting acquirer in the business combination, we will inherit this material weakness and the Warrants. We cannot assure as to when this material weaknesses will be remediated.

As a result of such material weakness, the change in accounting for the Novus Warrants and the Novus Common Stock, and other matters raised or that may in the future be raised by the SEC, we face potential for litigation or other disputes which may include, among others, claims invoking the federal and state securities laws, contractual claims or other claims arising from the material weaknesses in our internal control over financial reporting and the preparation of our financial statements. As of the date of this prospectus/proxy statement, we have no knowledge of any such litigation or dispute. However, we can provide no assurance that such litigation or dispute will not arise in the future. Any such litigation or dispute, whether successful or not, could have a material adverse effect on our business, results of operations and financial condition or our ability to complete the Business Combination.

We cannot assure you that there will not be additional material weaknesses in our internal control over financial reporting now or in the future. Any failure to maintain internal control over financial reporting could severely inhibit our ability to accurately report our financial condition, results of operations or cash flows. If we are unable to conclude that our internal control over financial reporting is effective, or if our independent registered public accounting firm determines that we have a material weakness in our internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports, the market price of Combined Company Common Stock could decline, and it could be subject to sanctions or investigations by Nasdaq, the SEC or other regulatory authorities. Failure to remedy any material weakness in our internal control over financial reporting, or to implement or maintain other effective control systems required of public companies, could also restrict our future access to the capital markets.

The unavailability, reduction or elimination of government and economic incentives could negatively impact the Combined Company’s business, prospects, financial condition and operating results.

Any reduction, elimination or discriminatory application of government subsidies and economic incentives because of policy changes, the reduced need for such subsidies and incentives due to the perceived

TABLE OF CONTENTS

success of Energy Vault’s operations or other reasons may result in the diminished competitiveness of the controlled environment agriculture facility industry generally or the Combined Company’s products in particular. This could materially and adversely affect the growth of the controlled environment agriculture facility markets and the Combined Company’s business, prospects, financial condition and operating results.

Following the consummation of the Business Combination, the Combined Company will incur significant increased expenses and administrative burdens as a public company, which could negatively impact its business, financial condition and results of operations.

Following the consummation of the Business Combination, the Combined Company will face increased legal, accounting, administrative and other costs and expenses as a public company that Energy Vault does not incur as a private company. The Sarbanes-Oxley Act, including the requirements of Section 404, as well as rules and regulations subsequently implemented by the SEC, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and the rules and regulations promulgated and to be promulgated thereunder, the PCAOB and the securities exchanges, impose additional reporting and other obligations on public companies. Compliance with public company requirements will increase costs and make certain activities more time-consuming. A number of those requirements will require the Combined Company to carry out activities Energy Vault has not done previously. For example, the Combined Company will create new board committees and adopt new internal controls and disclosure controls and procedures. In addition, expenses associated with SEC reporting requirements will be incurred. Furthermore, if any issues in complying with those requirements are identified (for example, if the auditors identify a material weakness or significant deficiency in the internal control over financial reporting), the Combined Company could incur additional costs rectifying those issues, and the existence of those issues could adversely affect the Combined Company’s reputation or investor perceptions of it. It may also be more expensive to obtain director and officer liability insurance. Risks associated with the Combined Company’s status as a public company may make it more difficult to attract and retain qualified persons to serve on the Combined Company’s board of directors or as executive officers. The additional reporting and other obligations imposed by these rules and regulations will increase legal and financial compliance costs and the costs of related legal, accounting and administrative activities. These increased costs will require the Combined Company to divert a significant amount of money that could otherwise be used to expand the business and achieve strategic objectives. Advocacy efforts by stockholders and third parties may also prompt additional changes in governance and reporting requirements, which could further increase costs.

The Combined Company’s failure to timely and effectively implement controls and procedures required by Section 404(a) of the Sarbanes-Oxley Act that will be applicable to it after the Business Combination is consummated could negatively impact its business.

Energy Vault is currently not subject to Section 404 of the Sarbanes-Oxley Act. However, following the consummation of the Business Combination, the Combined Company will be required to provide management’s attestation on internal controls. The standards required for a public company under Section 404(a) of the Sarbanes-Oxley Act are significantly more stringent than those required of Energy Vault as a privately held company. Management may not be able to effectively and timely implement controls and procedures that adequately respond to the increased regulatory compliance and reporting requirements that will be applicable after the Business Combination. If the Combined Company is not able to implement the additional requirements of Section 404(a) in a timely manner or with adequate compliance, it may not be able to assess whether its internal controls over financial reporting are effective, which may subject it to adverse regulatory consequences and could harm investor confidence and the market price of its securities.

The Combined Company will qualify as an “emerging growth company” and “smaller reporting company”within the meaning of the Securities Act, and if it takes advantage of certain exemptions from disclosure requirements available to emerging growth companies, it could make the Combined Company’s securities less attractive to investors and may make it more difficult to compare the Combined Company’s performance to the performance of other public companies.

The Combined Company will qualify as an “emerging growth company” as defined in Section 2(a)(19) of the Securities Act, as modified by the JOBS Act. As such, the Combined Company will be eligible for and intends to take advantage of certain exemptions from various reporting requirements applicable to other

TABLE OF CONTENTS

public companies that are not emerging growth companies for as long as it continues to be an emerging growth company, including (a) the exemption from the auditor attestation requirements with respect to internal control over financial reporting under Section 404(b) of the Sarbanes-Oxley Act, (b) the exemptions from say-on-pay, say-on-frequency and say-on-golden parachute voting requirements and (c) reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements. The Combined Company will remain an emerging growth company until the earliest of (i) the last day of the fiscal year in which the market value of Combined Company Common Stock that is held by non-affiliates exceeds $700 million as of June 30 of that fiscal year, (ii) the last day of the fiscal year in which it has total annual gross revenue of $1.07 billion or more during such fiscal year (as indexed for inflation), (iii) the date on which it has issued more than $1 billion in non-convertible debt in the prior three-year period or (iv) December 31, 2026. In addition, Section 107 of the JOBS Act also provides that an emerging growth company can take advantage of the exemption from complying with new or revised accounting standards provided in Section 7(a)(2)(B) of the Securities Act as long as the Combined Company is an emerging growth company. An emerging growth company can therefore delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected not to opt out of such extended transition period and, therefore, the Combined Company may not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

Even after the Combined Company no longer qualifies as an emerging growth company, it may still qualify as a “smaller reporting company,” which would allow it to continue to take advantage of many of the same exemptions from disclosure requirements, including not being required to comply with the auditor attestation requirements, Section 404 of the Sarbanes-Oxley Act and reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements. Moreover, smaller reporting companies may choose to present only the two most recent fiscal years of audited financial statements in their Annual Reports on Form 10-K.

Investors may find Combined Company Common Stock less attractive because the Combined Company will rely on these exemptions, which may result in a less active trading market for the Combined Company Common Stock and its price may be more volatile.

Energy Vault’s management has limited experience in operating a public company.

Energy Vault’s executive officers have limited experience in the management of a publicly traded company. Energy Vault’s management team may not successfully or effectively manage its transition to a public company that will be subject to significant regulatory oversight and reporting obligations under federal securities laws. Their limited experience in dealing with the increasingly complex laws pertaining to public companies could be a significant disadvantage in that it is likely that an increasing amount of their time may be devoted to these activities which will result in less time being devoted to the management and growth of the Combined Company. Energy Vault may not have adequate personnel with the appropriate level of knowledge, experience, and training in the accounting policies, practices or internal controls over financial reporting required of public companies in the United States. The development and implementation of the standards and controls necessary for the Combined Company to achieve the level of accounting standards required of a public company in the United States may require costs greater than expected. It is possible that the Combined Company will be required to expand its employee base and hire additional employees to support its operations as a public company which will increase its operating costs in future periods.

If, following the Business Combination, securities or industry analysts do not publish or cease publishing research or reports about the Combined Company, its business, or its market, or if they change their recommendations regarding the Combined Company’s securities adversely, the price and trading volume of the Combined Company’s securities could decline.

The trading market for the Combined Company’s securities will be influenced by the research and reports that industry or securities analysts may publish about the Combined Company, its business, market or competitors. Securities and industry analysts do not currently, and may never, publish research on the Combined Company. If no securities or industry analysts commence coverage of the Combined Company, the Combined Company’s share price and trading volume would likely be negatively impacted. If any of the analysts who may cover the Combined Company change their recommendation regarding the Combined

TABLE OF CONTENTS

Company’s shares of common stock adversely, or provide more favorable relative recommendations about its competitors, the price of the Combined Company’s shares of common stock would likely decline. If any analyst who may cover the Combined Company were to cease coverage of the Combined Company or fail to regularly publish reports on it, the Combined Company could lose visibility in the financial markets, which in turn could cause its share price or trading volume to decline.

If the Combined Company’s security holders use their registration rights to sell under the Combined Company’s resale registration statement, it may negatively impact the market price of the Combined Company’s shares of common stock.

In connection with the Closing, Novus’ existing registration rights agreement will be amended and restated to: (i) provide that Novus will file a registration statement within the later of 30 calendar days following the Closing and 20 business days following the Closing to register for resale (A) the Founder Shares, Private Warrants and shares of Combined Company Common Stock issuable upon exercise of the Private Warrants held by the Founders (B) the shares of the Combined Company Common Stock to be issued to Energy Vault’s stockholders in the Business Combination; (ii) provide the Founders and Energy Vault’s stockholders with demand registration rights; (iii) provide Energy Vault’s stockholders and the Founders customary underwritten takedown rights (subject to customary priorities, minimums, frequency, and quantity limits, cutbacks, deferrals and other terms); and (iv) afford each of Energy Vault’s stockholders and the Founders, on a pari passu basis, “piggy back” registration rights with respect to any underwritten offerings by the other stockholders and by the Combined Company.

Further, pursuant to the Subscription Agreements, Novus agreed that, within the later of 30 calendar following the Closing and 20 business days following the Closing, the Combined Company will file a registration statement with the SEC (at Novus’s sole cost and expense) to cover shares issuable to PIPE Subscribers. It is currently intended that one registration statement will be filed to discharge Novus’s obligations under the registration rights agreement and the Subscription Agreements. Such registration statement is also expected to cover shares issuable upon exercise of the Public Warrants. Additionally, the Combined Company will likely register for resale shares subject to the Exchanged Options and Converted RSUs.

The sale or possibility of sale of these additional securities trading in the public market may negatively impact the market price of the Combined Company’s securities.

Because we have no current plans to pay cash dividends on the Combined Company’s common stock for the foreseeable future, you may not receive any return on investment unless you sell the Combined Company’s common stock for a price greater than that which you paid for it.

The Combined Company may retain future earnings, if any, for future operations, expansion and debt repayment and has no current plans to pay any cash dividends for the foreseeable future. Any decision to declare and pay dividends as a public company in the future will be made at the discretion of the Combined Company’s board of directors and will depend on, among other things, the Combined Company’s results of operations, financial condition, cash requirements, contractual restrictions and other factors that the Combined Company’s board of directors may deem relevant. In addition, the Combined Company’s ability to pay dividends may be limited by covenants of any existing and future outstanding indebtedness it or its subsidiaries incur. As a result, you may not receive any return on an investment in the Combined Company’s common stock unless you sell your shares of common stock for a price greater than that which you paid for it.

The Combined Company may issue additional shares of common stock or other equity securities without your approval, which would dilute your ownership interests and may depress the market price of the Combined Company’s common stock.

Upon consummation of the Business Combination, the Combined Company will have warrants outstanding to purchase an aggregate of 14,749,999 shares of common stock. Pursuant to the 2022 Plan, following the consummation of the Proposed Transactions, the Combined Company may issue an aggregate of up to 15,516,760 shares of common stock, which amount may be subject to increase from time to time. For additional information about this plan, please read the discussion under the headings “Proposal

TABLE OF CONTENTS

No. 3 — The Equity Incentive Plan Proposal,” and “Energy Vault’s Executive Compensation — Employee Benefit Plans.” The Combined Company may also issue additional shares of common stock or other equity securities of equal or senior rank in the future in connection with, among other things, future acquisitions or repayment of outstanding indebtedness, without stockholder approval, in a number of circumstances.

The issuance of additional shares or other equity securities of equal or senior rank would have the following effects:

•

existing stockholders’ proportionate ownership interest in the Combined Company will decrease;

•

the amount of cash available per share, including for payment of dividends in the future, may decrease;

•

the relative voting strength of each previously outstanding common stock may be diminished; and

•

the market price of the Combined Company’s common stock may decline.

Anti-takeover provisions in the Proposed Certificate and under Delaware law could make an acquisition of the Combined Company, which may be beneficial to its stockholders, more difficult and may prevent attempts by its stockholders to replace or remove the Combined Company’s then current management.

The Proposed Certificate contains provisions that may delay or prevent an acquisition of the Combined Company or a change in its management. These provisions may make it more difficult for stockholders to replace or remove members of its board of directors. Because the board of directors is responsible for appointing the members of the management team, these provisions could in turn frustrate or prevent any attempt by its stockholders to replace or remove its current management. In addition, these provisions could limit the price that investors might be willing to pay in the future for shares of Combined Company Common Stock. Among other things, these provisions include:

•

the limitation of the liability of, and the indemnification of, its directors and officers;

•

a prohibition on actions by its stockholders except at an annual or special meeting of stockholders;

•

a prohibition on actions by its stockholders by written consent; and

•

the ability of the board of directors to issue preferred stock without stockholder approval, which could be used to institute a “poison pill” that would work to dilute the stock ownership of a potential hostile acquirer, effectively preventing acquisitions that have not been approved by the board of directors.

Moreover, because the Combined Company is incorporated in Delaware, it is governed by the provisions of Section 203 of the DGCL, which prohibits a person who owns 15% or more of its outstanding voting stock from merging or combining with the Combined Company for a period of three years after the date of the transaction in which the person acquired 15% or more of the Combined Company’s outstanding voting stock, unless the merger or combination is approved in a prescribed manner. This could discourage, delay or prevent a third party from acquiring or merging with the Combined Company, whether or not it is desired by, or beneficial to, its stockholders. This could also have the effect of discouraging others from making tender offers for the Combined Company’s common stock, including transactions that may be in its stockholders’ best interests. Finally, these provisions establish advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted upon at stockholder meetings. These provisions would apply even if the offer may be considered beneficial by some stockholders. For more information, see the section titled “Description of Securities — Certain Anti-Takeover Provisions of Delaware Law.”

Risks Related to Novus

Unless the context otherwise requires, all references to “we,” “us,” or “our” in this subsection titled “Risks Related to Novus” refer to Novus.

Novus’s Quarterly Report on Form 10-Q contains an explanatory paragraph that expresses substantial doubt about Novus’s ability to continue as a “going concern.” As of September 30, 2021, Novus had $882,585 in cash and a working capital of $769,399. Further, Novus has incurred and expects to continue to incur

TABLE OF CONTENTS

significant costs in pursuit of its finance and acquisition plans. It cannot be assured that Novus’s plans to raise capital or to consummate an initial business combination will be successful. These factors, among others, raise substantial doubt about Novus’s ability to continue as a going concern. The condensed consolidated financial statements contained in Novus’s Quarterly Report on Form 10-Q do not include any adjustments that might result from Novus’s inability to continue as a going concern.

Novus’s executive officers, directors, other Founders have agreed to vote in favor of the Business Combination, regardless of how the Public Stockholders vote.

Unlike many other blank check companies in which the executive officers, directors and other initial stockholders agree to vote their Founder Shares in accordance with the majority of the votes cast by the Public Stockholders in connection with an initial business combination, Novus’s executive officers, directors and the other Founders have agreed (and their permitted transferees will agree), pursuant to the terms of a letter agreement entered into with Novus, to vote any shares of Novus Common Stock and Novus Class B Common Stock held by them in favor of the Business Combination. Novus’s executive officers, directors and other Founders (and their permitted transferees) own at least approximately 20% of the issued and outstanding shares of Novus Common Stock as of the Record Date. Accordingly, it is more likely that the necessary stockholder approval will be received than would be the case if such persons agreed to vote their Initial Stockholder Shares in accordance with the majority of the votes cast by the Public Stockholders.

The exercise of Novus’s directors’ and officers’ discretion in agreeing to changes or waivers in the terms of the Business Combination may result in a conflict of interest when determining whether such changes to the terms of the Business Combination or waivers of conditions are appropriate and in Novus’s stockholders’ best interest.

In the period leading up to the closing of the Business Combination, events may occur that, pursuant to the Business Combination Agreement, would require Novus to agree to amend the Business Combination Agreement, to consent to certain actions taken by Energy Vault or to waive rights that Novus is entitled to under the Business Combination Agreement. Such events could arise because of changes in the course of Energy Vault’s business, a request by Energy Vault to undertake actions that would otherwise be prohibited by the terms of the Business Combination Agreement or the occurrence of other events that would have a material adverse effect on Energy Vault’s business and would entitle Novus to terminate the Business Combination Agreement. In any of such circumstances, it would be at Novus’s discretion, acting through its board of directors, to grant its consent or waive those rights. The existence of the financial and personal interests of the directors described in the preceding risk factors may result in a conflict of interest on the part of one or more of the directors between what he or they may believe is best for Novus and what he or they may believe is best for himself or themselves in determining whether or not to take the requested action. As of the date of this proxy statement/prospectus, Novus does not believe there will be any material changes or waivers that Novus’s directors and officers would be likely to make after the mailing of this proxy statement/prospectus. Novus will circulate a new or amended proxy statement/prospectus if changes to the terms of the Business Combination that would have a material impact on its stockholders are required prior to the vote on the Business Combination Proposal.

If Novus is unable to complete the Business Combination or another business combination by February 8, 2023, Novus will cease all operations except for the purpose of winding up, redeeming 100% of the outstanding Public Shares and, subject to the approval of its remaining stockholders and its board of directors, dissolving and liquidating. In such event, third parties may bring claims against Novus and, as a result, the proceeds held in the Trust Account could be reduced and the per-share liquidation price received by stockholders could be less than $10.00 per share.

Under the terms of the Existing Certificate of Incorporation, Novus must complete an initial business combination by February 3, 2023, or Novus must cease all operations except for the purpose of winding up, redeeming 100% of the outstanding Public Shares and, subject to the approval of its remaining stockholders and its board of directors, dissolving and liquidating. In such event, third parties may bring claims against Novus. Although Novus has obtained waiver agreements from certain vendors and service providers it has engaged and owes money to, and the prospective target businesses it has negotiated with, whereby such parties have waived any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account, there is no guarantee that they or other vendors who did not execute such waivers will not

TABLE OF CONTENTS

seek recourse against the Trust Account notwithstanding such agreements. Furthermore, there is no guarantee that a court will uphold the validity of such agreements. Accordingly, the proceeds held in the Trust Account could be subject to claims which could take priority over those of Novus’s Public Stockholders. If Novus is unable to complete a business combination within the required time period, V Donargo LLC, an entity controlled by Vincent Donargo, its Chief Financial Officer, has agreed it will be y liable under certain circumstances described herein to ensure that the proceeds in the Trust Account are not reduced by the claims of target businesses or claims of vendors or other entities that are owed money by Novus for services rendered or contracted for or products sold to Novus. However, V Donargo LLC may not be able to meet such obligation. Therefore, the per-share distribution from the Trust Account in such a situation may be less than $10.00 due to such claims.

Additionally, if Novus is forced to file a bankruptcy case or an involuntary bankruptcy case is filed against it which is not dismissed, or if Novus otherwise enters compulsory or court supervised liquidation, the proceeds held in the Trust Account could be subject to applicable bankruptcy law, and may be included in its bankruptcy estate and subject to the claims of third parties with priority over the claims of its stockholders. To the extent any bankruptcy claims deplete the Trust Account, Novus may not be able to return to its public stockholders at least $10.00 per Public Share.

For illustrative purposes, based on funds in the Trust Account of approximately $287.5 million on [*], 2022, the estimated per share redemption price would have been approximately $10.00.

Novus’s directors, executive officers, advisors or their affiliates may take actions, which may influence the vote on the Business Combination Proposal and other Stockholder Proposals and reduce the public “float” and have a depressive effect on the market price of Novus Common Stock.

At any time prior to the special meeting of stockholders, during which they are not aware of any non-material public information about Novus or its securities, Novus’s directors, executive officers, advisors or their affiliates may purchase shares in privately negotiated transactions or in the open market either prior to or following the completion of the Business Combination, although they are under no obligation to do so. Such a purchase may include a contractual acknowledgement that such stockholder, although still the record holder of Novus’s shares is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights. In the event that Novus’s directors, executive officers, advisors or their affiliates purchase shares in privately negotiated transactions from Public Stockholders who have already elected to exercise their redemption rights, such selling stockholders would be required to revoke their prior elections to redeem their shares. In addition, they may enter into transactions with investors and others to provide them with incentives to acquire shares of Novus Common Stock. The purpose of such purchases and other transactions could be to vote such shares in favor of the Business Combination and thereby increase the likelihood of obtaining stockholder approval of the Business Combination, where it appears that such requirement would otherwise not be met. This may result in the completion of the Business Combination that may not otherwise have been possible. If such purchases are made, the public “float” of Novus Common Stock and the number of beneficial holders of our securities may be reduced, possibly making it difficult to maintain or obtain the quotation, listing or trading of Novus’s securities on a national securities exchange.

In addition, pursuant to the Subscription Agreements, certain of our officers and directors and their affiliates have agreed to purchase an aggregate of 1,100,000 shares of Novus Common Stock at a purchase price of $10.00 per share in the PIPE upon the Closing. Such purchases may, therefore, be at a price per share that is less than the then-current market price of Novus’s Common Stock and could have a depressive effect on the market price of Novus’s Common Stock.

Novus’s ability to successfully effect the Business Combination and the Combined Company’s ability to successfully operate the business thereafter will be largely dependent upon the efforts of certain key personnel of Energy Vault. The loss of such key personnel could negatively impact the operations and financial results of the combined business.

Novus’s ability to successfully effect the Business Combination and the Combined Company’s ability to successfully operate the business following the Closing is dependent upon the efforts of certain key personnel of Energy Vault. Although we expect key personnel to remain with the Combined Company following the Business Combination, there can be no assurance that they will do so. It is possible that Energy

TABLE OF CONTENTS

Vault will lose some key personnel, the loss of which could negatively impact the operations of the Combined Company. Furthermore, following the Closing, most of the key personnel of Energy Vault are unfamiliar with the requirements of operating a company regulated by the SEC, which could cause the Combined Company to have to expend time and resources helping them become familiar with such requirements.

Public Stockholders will not have any rights or interests in funds from the Trust Account, except under certain limited circumstances. To liquidate their investment, therefore, Public Stockholders may be forced to sell their securities, potentially at a loss.

Public Stockholders shall be entitled to receive funds from the Trust Account only (i) in the event of a redemption to Public Stockholders prior to any winding up in the event Novus does not consummate its initial business combination or its liquidation, (ii) if they redeem their shares in connection with an initial business combination that Novus consummates or, (iii) if they redeem their shares in connection with a stockholder vote to amend the Existing Certificate of Incorporation (A) to modify the substance or timing of Novus’s obligation to redeem 100% of the Public Shares if Novus does not complete its initial business combination within 24 months from the closing of the IPO or (B) with respect to any other provision relating to Novus’s pre-business combination activity and related stockholders’ rights. In no other circumstances will a stockholder have any right or interest of any kind to the funds in the Trust Account. Accordingly, to liquidate their investment, the Public Stockholders may be forced to sell their securities, potentially at a loss.

If third parties bring claims against Novus, the proceeds held in the Trust Account could be reduced and the per share redemption amount received by stockholders may be less than $10.00 per share.

Novus’s placing of funds in the Trust Account may not protect those funds from third-party claims against Novus. Although Novus has sought to have all vendors, service providers (other than its independent registered public accounting firm), prospective target businesses or other entities with which it does business execute agreements with Novus waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account for the benefit of the Public Stockholders, such parties may not execute such agreements, or even if they execute such agreements they may not be prevented from bringing claims against the Trust Account, including, but not limited to, fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case, in order to gain advantage with respect to a claim against Novus’s assets, including the funds held in the Trust Account. If any third party refuses to execute an agreement waiving such claims to the monies held in the Trust Account, Novus’s management will perform an analysis of the alternatives available to it and will only enter into an agreement with a third party that has not executed a waiver if management believes that such third party’s engagement would be significantly more beneficial to Novus than any alternative.

Examples of possible instances where Novus may engage a third party that refuses to execute a waiver include the engagement of a third-party consultant whose particular expertise or skills are believed by management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where Novus is unable to find a service provider willing to execute a waiver. In addition, there is no guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with us and will not seek recourse against the Trust Account for any reason. Upon redemption of our Public Shares, if Novus is unable to complete its initial business combination within the prescribed timeframe, or upon the exercise of a redemption right in connection with its initial business combination, Novus will be required to provide for payment of claims of creditors that were not waived that may be brought against Novus within the 10 years following redemption. Accordingly, the per share redemption amount received by Public Stockholders could be less than the $10.00 per share initially held in the Trust Account, due to claims of such creditors.

V Donargo LLC, an entity controlled by Vincent Donargo, the Chief Financial Officer of Novus, has agreed that it will be liable to Novus if and to the extent any claims by a third party (other than Novus’s independent registered public accounting firm) for services rendered or products sold to us, or a prospective target business with which Novus has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below $10.00 per Public Share, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under Novus’s indemnity of the underwriters of the IPO against certain liabilities, including liabilities under

TABLE OF CONTENTS

the Securities Act. Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, V Donargo LLC will not be responsible to the extent of any liability for such third-party claims. Novus has not independently verified whether V Donargo LLC has sufficient funds to satisfy its indemnity obligations and, therefore, V Donargo LLC may not be able to satisfy those obligations. Novus has not asked V Donargo LLC to reserve for such obligations. As a result, if any such claims were successfully made against the Trust Account, the funds available for Novus’s initial business combination and redemptions could be reduced to less than $10.00 per Public Share. In such event, Novus may not be able to complete its initial business combination, and its stockholders would receive such lesser amount per share in connection with any redemption of their Public Shares. Except to the extent of V Donargo LLC’s indemnification obligations described above, none of Novus’s officers or directors will indemnify Novus for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

Novus’s directors may decide not to enforce indemnification obligations against V Donargo LLC, resulting in a reduction in the amount of funds in the Trust Account available for distribution to the Public Stockholders.

In the event that the proceeds in the Trust Account are reduced below $10.00 per Public Share and V Donargo LLC asserts that it is unable to satisfy obligations or that he has no indemnification obligations related to a particular claim, Novus’s independent directors would determine on Novus’s behalf whether to take legal action against V. Donargo LLC to enforce its indemnification obligations. While Novus currently expects that its independent directors would take legal action on Novus’s behalf against V Donargo LLC to enforce its indemnification obligations to Novus, it is possible that Novus’s independent directors in exercising their business judgment may choose not to do so in any particular instance. If Novus’s independent directors choose not to enforce these indemnification obligations on Novus’s behalf, the amount of funds in the Trust Account available for distribution to the Public Stockholders may be reduced below $10.00 per Public Share.

If, after we distribute the proceeds in the trust account to our Public Stockholders, we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, a bankruptcy court may seek to recover such proceeds, and the members of our board of directors may be viewed as having breached their fiduciary duties to our creditors, thereby exposing the members of our board of directors and us to claims of punitive damages.

If, after we distribute the proceeds in the trust account to our Public Stockholders, we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, any distributions received by stockholders could be viewed under applicable debtor/creditor and/or bankruptcy laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy court could seek to recover some or all amounts received by our stockholders. In addition, our board of directors may be viewed as having breached its fiduciary duty to our creditors and/or having acted in bad faith by paying public stockholders from the trust account prior to addressing the claims of creditors, thereby exposing itself and us to claims of punitive damages.

If, before distributing the proceeds in the trust account to our public stockholders, we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, the claims of creditors in such proceeding may have priority over the claims of our stockholders and the per-share amount that would otherwise be received by our stockholders in connection with our liquidation may be reduced.

If, before distributing the proceeds in the trust account to our public stockholders, we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, the proceeds held in the trust account could be subject to applicable bankruptcy law, and may be included in our bankruptcy estate and subject to the claims of third parties with priority over the claims of our stockholders. To the extent any bankruptcy claims deplete the trust account, the per-share amount that would otherwise be received by our public stockholders in connection with our liquidation would be reduced.

Our stockholders may be held liable for claims by third parties against us to the extent of distributions received by them upon redemption of their shares.

Under the Delaware General Corporation Law, or the DGCL, stockholders may be held liable for claims by third parties against a corporation to the extent of distributions received by them in a dissolution.

TABLE OF CONTENTS

The pro rata portion of our Trust Account distributed to our Public Stockholders upon the redemption of our Public Shares in the event we do not complete our initial business combination within the required time period may be considered a liquidating distribution under Delaware law. If a corporation complies with certain procedures set forth in Section 280 of the DGCL intended to ensure that it makes reasonable provision for all claims against it, including a 60-day notice period during which any third-party claims can be brought against the corporation, a 90-day period during which the corporation may reject any claims brought, and an additional 150-day waiting period before any liquidating distributions are made to stockholders, any liability of stockholders with respect to a liquidating distribution is limited to the lesser of such stockholder’s pro rata share of the claim or the amount distributed to the stockholder, and any liability of the stockholder would be barred after the third anniversary of the dissolution. However, it is our intention to redeem our Public Shares as soon as reasonably possible following the 24th month from the closing of this offering (or the end of any Extension Period) in the event we do not complete our initial business combination and, therefore, we do not intend to comply with the foregoing procedures.

Because we do not intend to comply with Section 280, Section 281(b) of the DGCL requires us to adopt a plan, based on facts known to us at such time that will provide for our payment of all existing and pending claims or claims that may be potentially brought against us within the 10 years following our dissolution. However, because we are a blank check company, rather than an operating company, and our operations will be limited to searching for prospective target businesses to acquire, the only likely claims to arise would be from our vendors (such as lawyers, investment bankers, consultants, etc.) or prospective target businesses. If our plan of distribution complies with Section 281(b) of the DGCL, any liability of stockholders with respect to a liquidating distribution is limited to the lesser of such stockholder’s pro rata share of the claim or the amount distributed to the stockholder, and any liability of the stockholder would likely be barred after the third anniversary of the dissolution. We cannot assure you that we will properly assess all claims that may be potentially brought against us. As such, our stockholders could potentially be liable for any claims to the extent of distributions received by them (but no more) and any liability of our stockholders may extend beyond the third anniversary of such date. Furthermore, if the pro rata portion of our trust account distributed to our public stockholders upon the redemption of our Public Shares in the event we do not complete our initial business combination within the required time period is not considered a liquidating distribution under Delaware law and such redemption distribution is deemed to be unlawful, then pursuant to Section 174 of the DGCL, the statute of limitations for claims of creditors could then be six years after the unlawful redemption distribution, instead of three years, as in the case of a liquidating distribution.

You may not have the same benefits as an investor in an underwritten public offering.

Energy Vault will become a publicly listed company upon the completion of the Business Combination. The Business Combination and the transactions described in this proxy statement/prospectus are not an underwritten initial public offering of Energy Vault’s securities and differ from an underwritten initial public offering in several significant ways, which include, but are not limited to, the following:

Like other business combinations and spin-offs, in connection with the Business Combination, you will not receive the benefits of the diligence performed by the underwriters in an underwritten public offering. Investors in an underwritten public offering may benefit from the role of the underwriters in such an offering. In an underwritten public offering, an issuer initially sells its securities to the public market via one or more underwriters, who distribute or resell such securities to the public. Underwriters have liability under the U.S. securities laws for material misstatements or omissions in a registration statement pursuant to which an issuer sells securities. Because the underwriters have a “due diligence” defense to any such liability by, among other things, conducting a reasonable investigation, the underwriters and their counsel conduct a due diligence investigation of the issuer. Due diligence in part entails engaging legal, financial and/or other experts to perform an investigation as to the accuracy of an issuer’s disclosure regarding, among other things, its business and financial results. Auditors of the issuer will also customarily deliver a “comfort” letter with respect to the financial information contained in the registration statement. The underwriters also customarily receive opinions and negative assurance letters from the issuer’s counsel and from their own counsel. In making their investment decision, investors have the benefit of such diligence in underwritten public offerings. In contrast, Novus and Energy Vault have each engaged a financial advisor (rather than underwriters) in connection with the Business Combination. While such financial advisors or their respective affiliates may

TABLE OF CONTENTS

act as underwriters in underwritten public offerings, the role of a financial advisor differs from that of an underwriter. For example, financial advisors do not act as intermediaries in the sale of securities and therefore do not face the same potential liability under the U.S. securities laws as underwriters. As a result, financial advisors typically do not undertake the same level of, or any, due diligence investigation of the issuer as is typically undertaken by underwriters.

In addition, because there are no underwriters engaged in connection with the Business Combination, prior to the opening of trading on the trading day immediately following the closing, there will be no book building process and no price at which underwriters initially sold shares to the public to help inform efficient and sufficient price discovery with respect to the initial post-closing trades on the NYSE. Therefore, buy and sell orders submitted prior to and at the opening of initial post-closing trading of the Combined Company Common Stock on the NYSE will not have the benefit of being informed by a published price range or a price at which the underwriters initially sold shares to the public, as would be the case in an underwritten initial public offering. There will be no underwriters assuming risk in connection with an initial resale of shares of the Combined Company Common Stock or helping to stabilize, maintain or affect the public price of the Combined Company Common Stock following the closing. Moreover, we will not engage in, and have not and will not, directly or indirectly, request the financial advisors to engage in, any special selling efforts or stabilization or price support activities in connection with the Combined Company Common Stock that will be outstanding immediately following the closing. All of these differences from an underwritten public offering of Energy Vault’s securities could result in a more volatile price for the Combined Company Common Stock.

Further, we will not conduct a traditional “roadshow” with underwriters prior to the opening of initial post-closing trading of the Combined Company Common Stock on the NYSE. There can be no guarantee that any information made available in this proxy statement/prospectus and/or otherwise disclosed or filed with the SEC will have the same impact on investor education as a traditional “roadshow” conducted in connection with an underwritten initial public offering. As a result, there may not be efficient or sufficient price discovery with respect to the Combined Company Common Stock or sufficient demand among potential investors immediately after the closing, which could result in a more volatile price for the Combined Company Common Stock.

In addition, the Founders, as well as their permitted transferees, have interests in the Business Combination that are different from or are in addition to our shareholders and that would not be present in an underwritten public offering of Energy Vault’s securities. Such interests may have influenced our board of directors in making their recommendation that you vote in favor of the approval of the Business Combination Proposal and the other proposals described in this proxy statement/prospectus.

Such differences from an underwritten public offering may present material risks to unaffiliated investors that would not exist if Energy Vault became a publicly listed company through an underwritten initial public offering instead of upon completion of the merger.

We may not hold an annual meeting of stockholders until after we consummate our initial business combination and you will not be entitled to any of the corporate protections provided by such a meeting.

We may not hold an annual meeting of stockholders until after we consummate our initial business combination (unless required by the NYSE) and thus may not be in compliance with Section 211(b) of the DGCL, which requires an annual meeting of stockholders be held for the purposes of electing directors in accordance with a company’s bylaws unless such election is made by written consent in lieu of such a meeting. Therefore, if our stockholders want us to hold an annual meeting prior to our consummation of our initial business combination, they may attempt to force us to hold one by submitting an application to the Delaware Court of Chancery in accordance with Section 211(c) of the DGCL. Until we hold an annual meeting of stockholders, public stockholders may not be afforded the opportunity to discuss company affairs with management. In addition, prior to our business combination (a) as holders of Novus common stock, our Public Stockholders will not have the right to vote on the appointment of our directors and (b) holders of a majority of the outstanding shares of Novus Class B common stock may remove a member of our board of directors for any reason.

TABLE OF CONTENTS

Novus’s executive officers and directors have potential conflicts of interest in recommending that stockholders vote in favor of approval of the Business Combination Proposal and approval of the other Stockholder Proposals described in this proxy statement/prospectus.

When considering Novus’s board of directors’ recommendation that our stockholders vote in favor of the approval of the Business Combination Proposal and the other Stockholder Proposals, Novus’s stockholders should be aware that Novus’s directors and executive officers have interests in the Business Combination that may be different from, in addition to, or in conflict with the interests of Novus’s stockholders. These interests include:

•

the beneficial ownership of Novus’s board of directors and officers of an aggregate of 4,869,662 shares of Novus Class B Common Stock and 2,900,625 Novus Warrants, which shares and warrants would become worthless if Novus does not complete a business combination within the applicable time period, as our directors and officers have waived any right to redemption with respect to these shares. Such shares and warrants have an aggregate market value of approximately $[*] million based on the closing prices of Novus Common Stock and warrants of $[*] and $[*], respectively on the NYSE on the Record Date for the special meeting of stockholders. Based on such market values, Novus’s board of directors and officers will have an unrealized gain of approximately $[*] million on their Novus securities;

•

our directors and officers and their affiliates have agreed to purchase an aggregate of 1,100,000 shares of Novus Common Stock in the PIPE at a purchase price of $10.00 per share, which purchase will not occur if Novus does not complete the Business Combination;

•

Messrs. Robert J. Laikin, Chief Executive Officer, a director and a principal stockholder of Novus, Larry Paulson, Chairman of the Board and a principal stockholder of Novus, and Jeffrey Foster, a director of Novus, each purchased a non-controlling membership interest in Helena SPV for $250,000. Each such membership interest will equate to an indirect interest of 119,632 shares of Combined Company Common Stock. Based on the closing sale price of Novus Common Stock on the Record Date, each such individual’s membership interest have a value of $ [ ] and will have an unrealized gain on this investment of $[•] (based on the closing sale price of the Novus Common Stock of $[ ] as of the Record Date) .

•

Novus’s board of directors will not receive reimbursement for any out-of-pocket expenses incurred by them on Novus’s behalf incident to identifying, investigating and consummating a business combination to the extent such expenses exceed the amount not required to be retained in the Trust Account, unless a business combination is consummated;

•

the anticipated continuation of Larry Paulson, as a director of the Combined Company following the Closing;

•

the continued indemnification of current directors and officers of Novus following the Business Combination and the continuation of directors’ and officers’ liability insurance following the Business Combination.

•

Each membership interests will have a value of $1,196,320 and each such director will have an unrealized gain on each director’s $250,000 investment of $946,320 (valued at $10.00 per share of Combined Company Common Stock, the per share transaction value).

Accordingly, our board of directors and officers and their affiliates will hold securities of Novus (directly or indirectly and excluding shares of Novus Common Stock which certain directors agreed to purchase in the PIPE) with an aggregate value of $[ ] based on the closing prices of Novus Common Stock and warrants of $[*] and $[*], respectively on the NYSE on the Record Date. For these reasons, our board of directors and officers and their affiliates will receive a benefit from the completion of the Business Combination. These interests may incentivize our directors and officers to complete a business combination of a less favorable target company or on terms less favorable to stockholders rather than liquidate and to vote in favor of approval of the Stockholder Proposals.

TABLE OF CONTENTS

In addition to the interests of Novus’s executive officers and directors and their affiliates described above, our Founders (other than our directors and officers) and their affiliates) will hold additional securities of Novus (directly or indirectly and excluding shares of Novus Common Stock which Founders or their affiliates agreed to purchase in the PIPE) and receive cash fees with an aggregate value of $[ ] based on the closing prices of Novus Common Stock and warrants of $[*] and $[*], respectively on the NYSE on the Record Date. For these reasons, our Founders (including our directors and officers) and their affiliates will receive a benefit from the completion of the Business Combination. These interests may incentivize our Founders (including our directors and officers) to complete a business combination of a less favorable target company or on terms less favorable to stockholders rather than liquidate and to vote in favor of approval of the Stockholder Proposals.

These financial interests may have influenced the decision of Novus’s directors to approve the Business Combination and to continue to pursue such Business Combination. In considering the recommendations of Novus’s board of directors to vote for the Business Combination Proposal and other Stockholder Proposals, its stockholders should consider these interests.

We may amend the terms of the Novus Warrants in a manner that may be adverse to holders with the approval by the holders of at least a majority of the then outstanding Public Warrants.

The Novus Warrants were issued in registered form under the Novus Warrant Agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. The Novus Warrant Agreement provides that the terms of the Novus Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision but requires the approval by the holders of at least a majority of the then outstanding Public Warrants prior to the Business Combination (or at least a majority of the then outstanding Novus Warrants after the Business Combination) to make any change that adversely affects the interests of the registered holders. Accordingly, we may amend the terms of the Novus Warrants in a manner adverse to a holder if holders of at least a majority of the then outstanding Public Warrants prior to the Business Combination (or at least a majority of the then outstanding Novus Warrants after the Business Combination) approve of such amendment. Although our ability to amend the terms of the Novus Warrants with the consent of at least a majority of the then outstanding Public Warrants prior to the Business Combination (or at least a majority of the then outstanding Novus Warrants after the Business Combination) is unlimited, examples of such amendments could be amendments to, among other things, increase the exercise price of the Novus Warrants, convert the Novus Warrants into stock or cash, shorten the exercise period or decrease the number of warrant shares issuable upon exercise of a Novus Warrant.

Novus’s Warrant Agreement designates the courts of the State of New York or the United States District Court for the Southern District of New York as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by holders of Novus’s warrants, which could limit the ability of warrant holders to obtain a favorable judicial forum for disputes with Novus.

Novus’s Warrant Agreement provides that, subject to applicable law, (i) any action, proceeding or claim against Novus arising out of or relating in any way to the Warrant Agreement will be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and (ii) that Novus irrevocably submit to such jurisdiction, which jurisdiction shall be the exclusive forum for any such action, proceeding or claim. Novus waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum.

Notwithstanding the foregoing, these provisions of the Warrant Agreement will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal district courts of the United States of America are the sole and exclusive forum. In addition, the Warrant Agreement provides that, unless Novus consents in writing to the selection of an alternative forum, the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act or the rules and regulations promulgated thereunder. Any person or entity purchasing or otherwise acquiring any interest in any of Novus’s warrants shall be deemed to have notice of and to have consented to the forum provisions in Novus’s warrant agreement. If any action, the subject matter of which is within the scope the forum provisions of the warrant agreement, is filed in a court other than a court of the State of

TABLE OF CONTENTS

New York or the United States District Court for the Southern District of New York (a “foreign action”) in the name of any holder of Novus’s warrants, such holder shall be deemed to have consented to: (x) the personal jurisdiction of the state and federal courts located in the State of New York in connection with any action brought in any such court to enforce the forum provisions (an “enforcement action”), and (y) having service of process made upon such warrant holder in any such enforcement action by service upon such warrant holder’s counsel in the foreign action as agent for such warrant holder.

This choice-of-forum provision may limit a warrant holder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with Novus, which may discourage such lawsuits. Alternatively, if a court were to find this provision of Novus’s warrant agreement inapplicable or unenforceable with respect to one or more of the specified types of actions or proceedings, Novus may incur additional costs associated with resolving such matters in other jurisdictions, which could materially and adversely affect Novus’s business, financial condition and results of operations and result in a diversion of the time and resources of Novus’s management and board of directors.

The Combined Company may redeem your unexpired Public Warrants prior to their exercise at a time that is disadvantageous to you, thereby making your Public Warrants worthless.

We have the ability to redeem outstanding Public Warrants at any time after they become exercisable and prior to their expiration, at a price of $0.01 per warrant if, among other things, the last reported sales price of our Class A common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30 trading-day period ending on the third trading day prior to the date we send the notice of redemption to the warrant holders. If and when the Public Warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. As a result, we may redeem the Public Warrants as set forth above even if the holders are otherwise unable to exercise the Public Warrants. The Public Warrants differ from the Private Warrants since none of the Private Warrants will be redeemable by us so long as they are held by our Founders or their permitted transferees. Accordingly, the Founders and their permitted transferees will receive a benefit not available to holders of the Public Warrants by being able to retain Private Warrants if we redeem the Public Warrants.

Redemption of the outstanding Public Warrants could force you to: (1) exercise your warrants and pay the exercise price therefor at a time when it may be disadvantageous for you to do so; (2) sell your warrants at the then-current market price when you might otherwise wish to hold your warrants; or (3) accept the nominal redemption price which, at the time the outstanding warrants are called for redemption, we expect would be substantially less than the market value of your warrants.

In addition, we have the ability to redeem outstanding Public Warrants commencing ninety days after they become exercisable and prior to their expiration, at a price of $0.10 per warrant if, among other things, the last reported sale price of our Novus Common Stock equals or exceeds $10.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) on the trading day prior to the date on which we send the notice of redemption to the warrant holders. As of , 2022, the last reported sale price of our Novus Common Stock was $ per share, which is less than the threshold required for redemption. In such a case, the holders will be able to exercise their warrants for cash or on a cashless basis prior to redemption and receive that number of shares of Class A common stock determined by reference to the table set forth under “Description of Novus Securities — Warrants” based on the redemption date and the “fair market value” of our Class A common stock (as defined below) except as otherwise described in “Description of Novus Securities — Warrants.” The value received upon exercise of the warrants (1) may be less than the value the holders would have received if they had exercised their warrants at a later time where the underlying share price is higher and (2) may not compensate the holders for the value of the warrants, including because the number of shares received is capped at 0.361 shares of Novus Common Stock per warrant (subject to adjustment) irrespective of the remaining life of the warrants. None of the Private Warrants will be redeemable by us so long as they are held by our Founders or their permitted transferees.

We will require Public Stockholders who wish to redeem their shares of Novus Common Stock in connection with the Business Combination to comply with specific requirements for redemption that may make it more difficult for them to exercise their redemption rights prior to the deadline for exercising their rights.

We will require the Public Stockholders seeking to exercise their redemption rights, whether they are record holders or hold their shares in “street name,” to either tender their certificates to our transfer agent

TABLE OF CONTENTS

up to two business days prior to the vote on the proposal to approve the Business Combination, or to deliver their shares to the transfer agent electronically using DTC’s Deposit/Withdrawal At Custodian System (“DWAC System”), at the holder’s option. In order to obtain a physical stock certificate, a stockholder’s broker and/or clearing broker, DTC and our transfer agent will need to act to facilitate this request. It is our understanding that stockholders should generally allot at least two weeks to obtain physical certificates from the transfer agent. However, because we do not have any control over this process or over the brokers or DTC, it may take significantly longer than two weeks to obtain a physical stock certificate. While we have been advised that it takes a short time to deliver shares through the DWAC System, this may not be the case. Under our bylaws, we are required to provide at least 10 days advance notice of any stockholder meeting, which would be the minimum amount of time a stockholder would have to determine whether to exercise redemption rights. Accordingly, if it takes longer than we anticipate for stockholders to deliver their shares, stockholders who wish to redeem may be unable to meet the deadline for exercising their redemption rights and thus may be unable to redeem their shares. In the event that a stockholder fails to comply with the various procedures that must be complied with in order to validly tender or redeem Public Shares, its shares may not be redeemed.

Additionally, despite our compliance with the proxy rules, stockholders may not become aware of the opportunity to redeem their shares.

If you or a “group” of stockholders of which you are a part are deemed to hold an aggregate of more than 15% of the shares of Novus Common Stock, you (or, if a member of such a group, all of the members of such group in the aggregate) will lose the ability to redeem all such shares in excess of 15% of the Novus Common Stock.

If we seek stockholder approval of our initial business combination and we do not conduct redemptions in connection with our initial business combination pursuant to the tender offer rules, our amended and restated certificate of incorporation will provide that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the shares sold in the IPO, which we refer to as the “Excess Shares,” without our prior consent.

However, our amended and restated certificate of incorporation does not restrict our stockholders’ ability to vote all of their shares (including Excess Shares) for or against our initial business combination. Your inability to redeem the Excess Shares will reduce your influence over our ability to complete our initial business combination and you could suffer a material loss on your investment in us if you sell Excess Shares in open market transactions.

Additionally, you will not receive redemption distributions with respect to the Excess Shares if we complete our initial business combination. And as a result, you will continue to hold that number of shares exceeding 15% and, in order to dispose of such shares, would be required to sell your stock in open market transactions, potentially at a loss.

There is uncertainty regarding the federal income tax consequences of the redemption to the holders of Novus Common Stock.

There is some uncertainty regarding the federal income tax consequences to holders of Novus Common Stock who exercise their redemption rights. The uncertainty of tax consequences relates primarily to the individual circumstances of the taxpayer and include (i) whether the redemption results in a distribution, taxable as ordinary income to the extent of Novus’s current and accumulated earnings and profits, or a sale, taxable as capital gain (assuming the redeemed Novus Common Stock is a capital asset in the hands of such taxpayer) to the extent the amount realized in the redemption exceeds such taxpayer’s tax basis in the redeemed Novus Common Stock, and (ii) whether such capital gain is “long-term” or “short-term.” If the redemption results in a distribution, the amount of the distribution in excess of our current and accumulated earnings and profits will constitute a return of capital that will be applied against and reduce (but not below zero) the taxpayer’s adjusted tax basis in Novus Common Stock, and the remaining amount of the distribution, if any, will constitute gain from the sale or exchange of Novus Common Stock. If the redemption results in a sale, a U.S. holder will recognize gain or loss in an amount equal to the difference

TABLE OF CONTENTS

between the amount realized in the redemption and the U.S. holder’s adjusted tax basis in the redeemed Novus Common Stock. Whether the redemption qualifies for sale treatment, resulting in taxation as capital gain rather than ordinary income, will depend largely on whether the holder owns (or is deemed to own) any shares of Novus Common Stock following the redemption, and if so, the total number of shares of Novus Common Stock held by the holder both before and after the redemption relative to all shares of Novus Common Stock outstanding both before and after the redemption. The redemption generally will be treated as a sale, rather than a distribution, if the redemption (i) is “substantially disproportionate” with respect to the holder, (ii) results in a “complete termination” of the holder’s interest in Novus or (iii) is “not essentially equivalent to a dividend” with respect to the holder. Due to the personal and subjective nature of certain of such tests and the absence of clear guidance from the IRS, there is uncertainty as to whether a holder who elects to exercise its redemption rights will be taxed on any gain from the redemption as ordinary income or capital gain. See the section titled “Certain U.S. Federal Income Tax Considerations of the Redemption and the Business Combination.”

The Novus Public Stockholders will experience dilution as a consequence of the issuance of Common Stock as consideration in the Business Combination and may experience dilution from several additional sources in connection with and after the Business Combination. Having a minority share position may reduce the influence that the Novus Public Stockholders have on the management of the Combined Company.

The issuance of additional shares of Common Stock in the Business Combination will dilute the equity interests of the Novus Public Stockholders and may adversely affect prevailing market prices for the public shares and Warrants. The Novus Public Stockholders who do not redeem their public shares may experience dilution from several additional sources:

•

An aggregate of 106,566,033 shares of Novus Common Stock are expected to be issued to Energy Vault Stockholders as consideration in the Business Combination;

•

An aggregate of 15,000,005 shares of Novus Common Stock are expected to be issued to the PIPE Subscribers upon closing of the PIPE;

•

An aggregate of 8,251,906 shares of Novus Common Stock may be issued upon exercise of Energy Vault Options and vesting of Energy Vault RSUs following the Business Combination;

•

An aggregate of 9,000,000 Earn Out Shares may eventually be issued to eligible Energy Vault equityholders;

•

An aggregate of 14,749,999 Warrants will be outstanding following the consummation of the Business combination, regardless of the number of Novus Common Stock the Novus Public Stockholders elect to have redeemed; and

The Combined Company may determine, subject to the receipt of any stockholder or stock exchange approvals that may be required, to issue additional shares of Combined Company Common Stock or other equity securities of equal or senior rank in connection with privately negotiated transactions following the consummation of the Business Combination, including equity awards under the 2022 Equity Incentive Plan.

Depending on the number of Novus Public Stockholders that exercise their redemption rights, the remaining Novus Public Stockholders will be subject to varying levels of dilution. In each of the no redemption, illustrative redemption, and contractual maximum redemption scenarios as described below, the residual equity value owned by non-redeeming stockholders, taking into account the respective redemption amounts, is assumed to remain the deemed value of $10.00 per share. As a result of such redemption amounts and the assumed $10.00 per share value, the implied total equity value of the Combined Company, assuming no dilution from any of the Public Warrants, Private Warrants, Energy Vault Options, Energy Vault RSUs or the Earn Out Shares (“Additional Dilution Sources”), would be (a) $1,567,847,880 in the no redemption scenario, (b) $1,410,738,500 in the illustrative redemption scenario, and (c) $1,267,121,500, in the contractual maximum redemption scenario.

This scenario assumes that no additional shares of Novus Common Stock are redeemed by the Public Stockholders and the Founders forfeit an aggregate of 718,750 Founder Shares.

(2)

This scenario assumes that approximately 14,375,000 shares of Novus Common Stock are redeemed by the Public Stockholders and the Founders forfeit an aggregate of 718,750 Founder Shares.

(3)

This scenario assumes that approximately 26,838,263 shares of Novus Common Stock are submitted for redemption by the public stockholders, which, based on the amount of $287,509,721 in the trust account as of September 30, 2021, represents the maximum amount of redemptions that would still enable Novus to have sufficient cash to satisfy the minimum cash condition in the Business Combination Agreement.

This row assumes the issuance of all shares of Combined Company Common Stock in connection with each of the Additional Dilution Sources, as described in Notes 8 through 11 above.

We may issue additional shares of common stock or preferred shares under the 2022 Plan upon or after consummation of the Business Combination, which would dilute the interest of our stockholders.

The Existing Certificate of Incorporation authorizes the issuance of 500,000,000 shares of Novus Common Stock, 20,000,000 of Novus Class B Common Stock and 5,000,000 shares of preferred stock. We may issue a substantial number of additional shares of common stock or shares of preferred stock under the 2022 Plan upon or after consummation of the Business Combination. For more information about the 2022 Plan, see “Proposal No. 3 — The Equity Incentive Plan Proposal.” However, the Existing Certificate of Incorporation provides that we may not issue any additional shares of capital stock that would entitle the holders thereof to receive funds from the Trust Account or vote as a class with our Public Shares on an initial business combination. Although no such issuance will affect the per share amount available for redemption from the Trust Account, the issuance of additional common stock or preferred shares:

•

may significantly dilute the equity interest of investors from the IPO, who will not have preemption rights in respect of such an issuance;

•

may subordinate the rights of holders of shares of common stock if one or more classes of preferred stock are created, and such shares of preferred stock are issued, with rights senior to those afforded to Novus Common Stock;

•

could cause a change in control if a substantial number of shares of common stock are issued, which may affect, among other things, our ability to use our net operating loss carry forwards, if any, and could result in the resignation or removal of our present officers and directors; and

•

may adversely affect prevailing market prices for our Novus Units, Novus Common Stock and/or Novus Warrants.

The Existing Certificate of Incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with our company or our company’s directors, officers or other employees.

The Existing Certificate of Incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for any (1) derivative action or proceeding brought on behalf of our company, (2) action asserting a claim of breach of a fiduciary duty owed by any director, officer, employee or agent of our company to our company or our stockholders, or any claim for aiding and abetting any such alleged breach, (3) action asserting a claim against our company or any director or officer of our company arising pursuant to any provision of the DGCL or our amended and restated certificate of incorporation or our bylaws, or (4) action asserting a claim against us or any director or officer of our company governed by the internal affairs doctrine except for, as to each of (1) through (4) above, any claim (a) as to which the Court of Chancery determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination), (b) which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery or (c) arising under the federal securities laws, including the Securities Act, as to which the Court of Chancery and the federal district court for the District of

TABLE OF CONTENTS

Delaware shall concurrently be the sole and exclusive forums. Notwithstanding the foregoing, the provisions of this paragraph will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal district courts of the United States of America shall be the sole and exclusive forum. Any person or entity purchasing or otherwise acquiring any interest in any shares of our capital stock shall be deemed to have notice of and to have consented to the forum provisions in our amended and restated certificate of incorporation. If any action the subject matter of which is within the scope the forum provisions is filed in a court other than a court located within the State of Delaware (a “foreign action”) in the name of any stockholder, such stockholder shall be deemed to have consented to: (x) the personal jurisdiction of the state and federal courts located within the State of Delaware in connection with any action brought in any such court to enforce the forum provisions (an “enforcement action”), and (y) having service of process made upon such stockholder in any such enforcement action by service upon such stockholder’s counsel in the foreign action as agent for such stockholder.

This forum selection clause may discourage claims or limit stockholders’ ability to submit claims in a judicial forum that they find favorable and may result in additional costs for a stockholder seeking to bring a claim. While we believe the risk of a court declining to enforce this forum selection clause is low, if a court were to determine the forum selection clause to be inapplicable or unenforceable in an action, we may incur additional costs in conjunction with our efforts to resolve the dispute in an alternative jurisdiction, which could have a negative impact on our results of operations and financial condition and result in a diversion of the time and resources of our management and board of directors.

Risks if the Adjournment Proposal is Not Approved

If the Adjournment Proposal is not approved, and an insufficient number of votes have been obtained to authorize the consummation of the Business Combination, Novus’s board of directors will not have the ability to adjourn the special meeting to a later date in order to solicit further votes, and, therefore, the Business Combination will not be approved.

Novus’s board of directors is seeking approval to adjourn the special meeting to a later date or dates if, at the special meeting, Novus is unable to consummate the Business Combination. If the Adjournment Proposal is not approved, Novus’s board of directors will not have the ability to adjourn the special meeting to a later date and, therefore, the Business Combination would not be completed.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Defined terms included below shall have the same meaning as terms defined and included elsewhere in this proxy statement/prospectus.

Introduction

Energy Vault, Inc. is providing the following unaudited pro forma condensed combined financial information to aid you in your analysis of the financial aspects of Energy Vault becoming a wholly-owned subsidiary of Novus Capital Corporation II as a result of NCII Merger Corp, a wholly-owned subsidiary of Novus, merging with and into Energy Vault, and Energy Vault surviving the merger as a wholly owned subsidiary of Novus (the “Proposed Transaction”). The consolidated Novus entity will change its name to Energy Vault Holdings, Inc. and thereafter be known as the “Combined Company.” The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses”. Release No. 33-10786 provides pro forma adjustment criteria with requirements to depict the accounting for the transaction (“Transaction Accounting Adjustments”) and present the reasonably estimable synergies and other transaction effects that have occurred or reasonably expected to occur (“Management’s Adjustments”). Energy Vault has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined financial information.

Novus is a blank check company formed under the laws of the State of Delaware on September 29, 2020, for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses. On February 8, 2021, Novus consummated its IPO of 28,750,000 Novus Units, with each Novus Unit consisting of one share of Novus Common Stock and one-third of one redeemable warrant, at a public offering price of $10.00 per Public Unit. Simultaneously with the closing of the IPO, Novus consummated the sale of 5,166,666 Private Warrants to Novus’s initial stockholders at a price of $1.50 per private warrant generating gross proceeds of $7,750,000. From the net proceeds from the IPO and the sale of the Private Warrants, $287,500,000 was placed in the Trust Account established for the benefit of the Novus’s public stockholders.

Energy Vault develops sustainable, grid-scale, energy storage solutions designed to advance the transition to a carbon free, resilient power grid. In July 2020, Energy Vault completed mechanical construction of a five megawatt commercial demonstration unit (the “CDU”) located in Arbedo-Castione, Switzerland based on the EV1 Tower design. In July 2020, the CDU was connected to the Swiss national electricity grid.

On September 8, 2021, Novus entered into a definitive agreement for a business combination that would result in Energy Vault becoming a wholly owned subsidiary of Novus. In connection with the execution of the Business Combination Agreement and in December 2021, Novus entered into Subscription Agreements with PIPE investors for the PIPE for the purpose of funding a portion of the Transaction and the costs and expenses incurred therein. Pursuant to the Subscription Agreements, Novus agreed to issue and sell to the PIPE investors 15,000,005 shares of Combined Company Common Stock at a price of $10.00 per share for an aggregate gross purchase price of $150,000,050.

The following unaudited pro forma condensed combined balance sheet as of September 30, 2021 assumes that the Transaction occurred on September 30, 2021. The unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2021 and year ended December 31, 2020 present pro forma effect to the Proposed Transaction as if it had been completed on January 1, 2020.

The unaudited pro forma condensed combined financial statements have been presented for illustrative purposes only and do not necessarily reflect what the Combined Company’s financial condition or results of operations would have been had the acquisition occurred on the dates indicated. Further, the pro forma condensed combined financial information also may not be useful in predicting the future financial condition and results of operations of the Combined Company. The actual financial position and results of operations may differ significantly from the pro forma amounts reflected herein due to a variety of factors.

TABLE OF CONTENTS

The historical financial information of Novus was derived from the unaudited and audited financial statements of Novus as of and for the nine months ended September 30, 2021 and for the period from September 29, 2020 (inception) to December 31, 2020, respectively, included elsewhere in this proxy statement/prospectus. The historical financial information of Energy Vault was derived from the unaudited and audited consolidated financial statements of Energy Vault as of and for the nine months ended September 30, 2021 and for the year ended December 31, 2020, respectively, included elsewhere in this proxy statement/prospectus. This information should be read together with the Novus’s and Energy Vault’s unaudited and audited financial statements and related notes, the sections titled “Novus’s Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and “Energy Vault’s Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other financial information included elsewhere in this proxy statement/prospectus.

The Proposed Transaction will be accounted for as a reverse recapitalization, in accordance with GAAP. Under this method of accounting, Novus will be treated as the “acquired” company for financial reporting purposes. Accordingly, the Proposed Transaction will be treated as the equivalent of Energy Vault issuing stock for the net assets of Novus, accompanied by a recapitalization. The net assets of Novus will be stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Proposed Transaction will be those of Energy Vault.

Energy Vault has been determined to be the accounting acquirer based on evaluation of the following facts and circumstances under both the minimum and maximum redemption scenarios:

•

Energy Vault has the largest portion of voting rights in the Combined Company;

•

Energy Vault has the right to appoint majority of the directors in the Combined Company;

•

Energy Vault’s existing senior management team will comprise senior management of the Combined Company;

•

The operations of the Combined Company will primarily represent operations of Energy Vault;

•

The Combined Company will assume Energy Vault’s name and headquarters

The unaudited pro forma condensed combined financial information has been prepared using the assumptions below with respect to the potential redemption into cash of common stock:

•

Description of the Proposed Transaction

The aggregate consideration to be received by the Energy Vault Stockholders in connection with the business combination is expected to be approximately an aggregate of $1.07 billion in the form of 106,566,033 shares, valued at $10.00 per share to the Combined Company.

Under the Business Combination Agreement, holders of Energy Vault Common Stock and Energy Vault Equity Awards as of immediately prior to the Effective Time are eligible to receive the Earn Out Shares. There are three tranches of Earn Out Shares each of which will be issued if the closing price of Common Stock as reported on Nasdaq exceeds price thresholds as specified in the Business Combination Agreement (each, a Triggering Event) for a period of at least twenty (20) days within the preceding thirty (30) consecutive trading days. The triggering Events must occur within the Earn Out Period. Each Triggering

TABLE OF CONTENTS

Event shall only occur once and in no event shall the eligible Energy Vault equity holders be entitled to receive more than (i) 3,000,000 Earn Out Shares with respect to a Triggering Event and (ii) an aggregate of 9,000,000 Earn Out Shares. If the earn out condition is achieved for a tranche, the Combined Company will account for the Earn Out Shares for such tranche as issued and outstanding Common Stock.

Novus also obtained commitments for the PIPE from certain investors for a private placement of 15,000,005 shares of common stock pursuant to the terms of the Subscription Agreements for an aggregate purchase price of approximately $150 million. In connection with the Proposed Transaction, the Founder Shares shall be held in escrow under restriction and be subject to potential forfeiture.

The restriction on 11.125 % of the Founder Shares equivalent to 808,594 shares shall be released upon the date on which:

(i)

The closing price of the Combined Company common stock exceeds $12.50 per share for any 20 trading days within a 30-trading day period occurring from the announcement of the PIPE through the thirty-six months anniversary of the Closing Date or

(ii)

Novus consummates a sale, merger, liquidation, exchange offer, transaction after the Merger which results in the stockholders of Novus having the right to exchange their shares of Combined Company Common stock for cash, securities or other property having a value of at least $12.50 per share,

The restrictions on an additional 11.125% of the Founder Shares equivalent to 808,594 Shares shall be released upon the date on which:

(i)

the closing price of the Combined Company common stock equals or exceeds $15.00 per share for any 20 trading days within a 30-trading day period occurring from the announcement of the PIPE through the thirty-six months anniversary of the Closing Date or

(ii)

Novus consummates a Subsequent Transaction which results in the stockholders of Novus having the right to exchange their shares of Combined Company common stock for cash, securities or other property having a value of at least $l5.00 per share,

In addition, 45% of the Founder Shares equivalent to 3,234,375 shares shall be subject to forfeiture (the “Forfeiture Percentage”) proportionately if redemptions of cash from the Trust Account held by the Trustee is in excess of $25,000,000. The forfeiture pertaining to Founder’s shares shall be calculated by (1) dividing (A) the aggregate dollar amount of cash redeemed from the Trust Account in excess of $25,000,000 by (B) $287,500,000 (the “Quotient”) and then (2) multiplying the Quotient by 45% of the 7,187,500 Founder Shares. Notwithstanding the foregoing, in the event that more than 26,250,000 shares of Novus Common Stock are redeemed from the Trust Account (resulting in $262,250,000 of cash redeemed from the Trust Account assuming a redemption price of $10.00 per share), such 3,234,375 Founder Shares shall be forfeited in lieu of applying the Forfeiture Percentage.

The following summarizes the pro forma common stock shares outstanding under the two redemption scenarios:

	Assuming No Redemptions (Shares)		%		Assuming Maximum Redemptions (Shares)		%
EV – Common Stock(1),(2)		106,566,033		68.7%		106,566,033		85.2%
Public Shares(3)		28,750,000		18.5%		1,911,737		1.5%

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Basis of Presentation

The Proposed Transaction will be accounted for as a reverse recapitalization in accordance with GAAP as Energy Vault has been determined to be the accounting acquirer, primarily due to the fact that Energy Vault shareholders will continue to control the Combined Company. Under this method of accounting, Novus will be treated as the “acquired” company for financial reporting purposes. Accordingly, the Proposed Transaction will be treated as the equivalent of Energy Vault issuing stock for the net assets of Novus, accompanied by a recapitalization. The net assets of the Novus will be stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Proposed Transaction will be those of Energy Vault.

The unaudited pro forma condensed combined balance sheet as of September 30, 2021 assumes that the Proposed Transaction occurred on September 30, 2021. The unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2021 and the year ended December 31, 2020 present pro forma effect to the Proposed Transaction as if it had been completed on January 1, 2020.

The unaudited pro forma condensed combined balance sheet as of September 30, 2021 has been prepared using, and should be read in conjunction with, the following:

•

Novus’s unaudited balance sheet as of September 30, 2021 and the related notes as of September 30, 2021, included elsewhere in this proxy statement/prospectus.

•

Energy Vault’s unaudited consolidated balance sheet as of September 30, 2021 and the related notes as of September 30, 2021, included elsewhere in this proxy statement/prospectus.

The unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2021 has been prepared using, and should be read in conjunction with, the following:

•

Novus’s unaudited statement of operations for the nine months ended September 30, 2021 and the related notes, included elsewhere in this proxy statement/prospectus; and

•

Energy Vault’s unaudited statement of operations for the nine months ended September 30, 2021 and the related notes, included elsewhere in this proxy statement/prospectus.

The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2020 has been prepared using, and should be read in conjunction with, the following:

•

Novus’s audited statement of operations for the period from September 29, 2020 (inception) to December 31, 2020 and the related notes, included elsewhere in this proxy statement/prospectus; and

•

Energy Vault’s audited statement of operations for the year ended December 31, 2020 and the related notes, included elsewhere in this proxy statement/prospectus.

Management of Novus and Energy Vault has made significant estimates and assumptions in its determination of the pro forma adjustments. As the unaudited pro forma condensed combined financial information has been prepared based on these preliminary estimates, the final amounts recorded may differ materially from the information presented.

The unaudited pro forma condensed combined financial information does not give effect to any anticipated synergies, operating efficiencies, tax savings, or cost savings that may be associated with the Proposed Transaction.

The unaudited pro forma condensed combined financial information does not reflect the income tax effects of the pro forma adjustments as any change in the deferred tax balance would be offset by an increase in the valuation allowance given that Energy Vault incurred significant losses during the historical periods presented.

The pro forma adjustments reflecting the consummation of the Proposed Transaction are based on certain currently available information and certain assumptions and methodologies that Novus believes are reasonable under the circumstances. The unaudited condensed pro forma adjustments, which are described in

102

TABLE OF CONTENTS

the accompanying notes, may be revised as additional information becomes available and is evaluated. Therefore, it is likely that the actual adjustments will differ from the pro forma adjustments and it is possible the difference may be material. Novus and Energy Vault believe that the assumptions and methodologies provide a reasonable basis for presenting all of the significant effects of the Proposed Transaction based on information available to management at this time and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined financial information is not necessarily indicative of what the actual results of operations and financial position would have been had the Proposed Transaction taken place on the dates indicated, nor are they indicative of the future consolidated results of operations or financial position of the Combined Company. They should be read in conjunction with the historical financial statements and notes thereto of Novus and Energy Vault.

Accounting Policies

Upon consummation of the Proposed Transaction, management will perform a comprehensive review of the two entities’ accounting policies. As a result of the review, management may identify differences between the accounting policies of the two entities which, when conformed, could have a material impact on the financial statements of the Combined Company. Based on its initial analysis, management did not identify any differences that would have a material impact on the unaudited pro forma condensed combined financial information. As a result, the unaudited pro forma condensed combined financial information does not assume any differences in accounting policies.

Adjustments to Unaudited Pro Forma Condensed Combined Financial Information

The unaudited pro forma condensed combined financial information has been prepared to illustrate the effect of the Proposed Transaction and has been prepared for informational purposes only.

The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses.” Release No. 33-10786 replaces the existing pro forma adjustment criteria with simplified requirements to depict the accounting for the transaction (“Transaction Accounting Adjustments”) and present the reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur (“Management’s Adjustments”). Novus has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the following unaudited pro forma condensed combined financial information.

Energy Vault and Novus have not had any historical relationship prior to the Transaction. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

The pro forma combined provision for income taxes does not necessarily reflect the amounts that would have resulted had the Combined Company filed consolidated income tax returns during the periods presented.

The pro forma basic and diluted earnings per share amounts presented in the unaudited pro forma condensed combined statements of operations are based upon the number of the Combined Company’s shares outstanding, assuming the Proposed Transaction occurred on January 1, 2020.

Adjustments to Unaudited Pro Forma Condensed Combined Balance Sheet

The adjustments included in the unaudited pro forma condensed combined balance sheet as of September 30, 2021 are as follows:

103

TABLE OF CONTENTS

Transaction Adjustments (assuming no redemptions):

(A)

Reflects the issuance of 15,000,005 shares of Novus Common Stock at a subscription price of $10.00 per share, pursuant to the Subscription Agreements, for proceeds of approximately $150.0 million. Issuance costs of $2.5 million in connection with the PIPE funding are included in the transaction costs discussed in (K) below.

(B)

Reflects the reclassification of $287.5 million of cash and cash equivalents held in Novus’s Trust Account at the balance sheet date that becomes available to fund the Proposed Transaction.

(C)

Reflects the reclassification of historical accumulated deficit to additional paid in capital of $15.4 million.

(D)

Reflects the settlement of Novus’s historical liabilities that will be settled at the closing of the Proposed Transaction.

(E)

Reflects the conversion of Energy Vault’s preferred stock into common stock pursuant to the Proposed Transaction.

(F)

Reflects the reclassification of approximately $287.5 million from temporary equity to permanent equity as a result of the Proposed Transaction, as following the Proposed Transaction such shares are no longer subject to possible redemption.

(G)

Reflects the acceleration of certain Energy Vault stock-based compensation awards that vest upon closing of the Proposed Transaction.

(H)

Represents recapitalization of Energy Vault equity and issuance of 20,626,221 of the combined company common stock (exclusive of 85,939,812 common stock shares issued in lieu of preferred stock conversion noted in Adjustment E) as the consideration for Business Combination, based on Exchange Ratio of 6.7892.

(I)

Reflects the settlement of estimated remaining transaction costs incurred as part of the Business Combination totaling $49.2 million, including approximately $2.5 million related PIPE issuance costs. The total estimated direct and incremental transaction costs consist of $46.6 million that qualify as equity issuance costs to be offset against additional paid in capital and $2.6 million which represents transaction costs that are not eligible to be capitalized which are recorded to accumulated deficit.

(J)

Represents reclassification of Novus Common Stock and Novus Class B Common Stock to the Combined Company Common Stock.

Additional Transaction Adjustments (Assuming Maximum Redemptions):

(K)

Reflects the maximum redemption of 26.8 million of Novus’s Public Shares for aggregate redemption payments of $268.4 million allocated to common stock and additional paid-in capital using a par value of $0.0001 per share and a redemption price of $10.00 per share.

(L)

Reflects the forfeiture of Novus Founder Shares proportionate to redemption of cash from the Trust Account. Under the maximum redemption scenario aggregate redemption payments of $268.4 million will result in 3,234,375 of the Founder Shares estimated to be forfeited, being 45% of the Founder Shares.

Adjustments to Unaudited Pro Forma Condensed Combined Statements of Operations

The pro forma adjustments included in the unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2021 and year ended December 31, 2020 are as follows:

(AA)

Reflects stock compensation expense related to certain Energy Vault stock-based compensation awards that vest upon the closing of the Proposed Transaction. The expense is reflected as if incurred on January 1, 2020, the date on which the Proposed Transaction occurred for the purposes of the unaudited pro forma condensed combined statement of operations.

104

TABLE OF CONTENTS

(BB)

Reflects elimination of interest income on the Trust Account.

(CC)

Reflects the payment of direct and incremental transaction costs in connection with the liability-classified warrant instruments of Novus, allocated on a relative fair value basis, for the year ended December 31, 2020. This is a non-recurring expense.

Loss per Share

Represents the net loss per share calculated using the historical weighted average shares outstanding and the issuance of additional shares in connection with the Proposed Transaction, assuming the shares were outstanding since January 1, 2020. As the Proposed Transaction and related proposed equity transactions are being reflected as if they had occurred at the beginning of the periods presented, the calculation of weighted average shares outstanding for basic and diluted net loss per share assumes that the shares issuable relating to the Proposed Transaction have been outstanding for the entire periods presented. If the maximum number of shares are redeemed, this calculation is retroactively adjusted to eliminate such shares for the entire periods.

The unaudited pro forma condensed combined financial information has been prepared assuming two alternative levels of redemption for the nine months ended September 30, 2021 and for the year ended December 31, 2020:

	For the Nine Months Ended September 30, 2021						For the Year ended December 31, 2020

Recommendation of Novus’s Board of Directors

Novus’s board of directors believes that each of the proposals to be presented at the special meeting of stockholders is in the best interests of Novus and its stockholders and unanimously recommends that its stockholders vote “FOR” each of the proposals.

When you consider the recommendation of Novus’s board of directors in favor of approval of the Business Combination Proposal and the other Stockholder Proposals, you should keep in mind that Novus’s directors and officers have interests in the Business Combination that are different from, in addition to, or in conflict with your interests as a stockholder. These interests include, among other things:

•

the beneficial ownership of Novus’s board of directors and officers of an aggregate of 4,869,662 shares of Novus Class B Common Stock and 2,900,625 Novus Warrants, which shares and warrants would become worthless if Novus does not complete a business combination within the applicable time period, as our directors and officers have waived any right to redemption with respect to these shares. Such shares and warrants have an aggregate market value of approximately $[*] million based on the closing prices of Novus Common Stock and warrants of $[*] and $[*], respectively on the NYSE on the Record Date for the special meeting of stockholders. Based on such market values, Novus’s board of directors and officers will have an unrealized gain of approximately $[*] million on their Novus securities;

•

Messrs. Robert J. Laikin, Chief Executive Officer, a director and a principal stockholder of Novus, Larry Paulson, Chairman of the Board and a principal stockholder of Novus, and Jeffrey Foster, a director of Novus, each purchased a non-controlling membership interest in Helena SPV for $250,000. Each such membership interest will equate to an indirect interest of 119,632 shares of Combined Company Common Stock. Based on the closing sale price of Novus Common Stock on the Record Date, each such individual’s membership interest have a value of $ [ ] and will have an unrealized gain on this investment of $[•] (based on the closing sale price of the Novus Common Stock of $[ ] as of the Record Date).

•

Novus’s board of directors will not receive reimbursement for any out-of-pocket expenses incurred by them on Novus’s behalf incident to identifying, investigating and consummating a business combination to the extent such expenses exceed the amount not required to be retained in the Trust Account, unless a business combination is consummated;

•

the anticipated continuation of Larry Paulson, as a director of the Combined Company following the Closing;

•

TABLE OF CONTENTS

Record Date and Voting

You will be entitled to vote or direct votes to be cast at the special meeting of stockholders if you owned shares of Novus Common Stock and/or Novus Class B Common Stock at the close of business on January [*], 2022, which is the Record Date for the special meeting of stockholders. You are entitled to one vote for each share of Novus Common Stock or Novus Class B Common Stock that you owned as of the close of business on the Record Date. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker, bank or other nominee to ensure that votes related to the shares you beneficially own are properly counted. On the Record Date, there were 35,937,500 shares of Novus Common Stock outstanding, of which 28,750,000 are shares of Novus Common Stock and 7,187,500 are shares of Novus Class B Common Stock or Founder Shares held by the Founders.

The Founders have agreed to vote all of their Founder Shares and any Public Shares acquired by them in favor of the Business Combination Proposal and the other Stockholder Proposals. Novus’s issued and outstanding Novus Warrants do not have voting rights at the special meeting of stockholders.

Voting Your Shares

Each share of Novus Common Stock and Novus Class B Common Stock that you own in your name entitles you to one vote on each of the proposals for the special meeting of stockholders. Your one or more proxy cards show the number of shares of Novus Common Stock and Novus Class B Common Stock that you own.

If you are a holder of record, there are two ways to vote your shares of Novus Common Stock and Novus Class B Common Stock at the special meeting of stockholders:

•

You can vote by completing, signing and returning the enclosed proxy card in the postage-paid envelope provided. If you hold your shares in “street name” through a bank, broker or other nominee, you will need to follow the instructions provided to you by your bank, broker or other nominee to ensure that your shares are represented and voted at the applicable special meeting(s). If you vote by proxy card, your “proxy,” whose name is listed on the proxy card, will vote your shares as you instruct on the proxy card. If you sign and return the proxy card but do not give instructions on how to vote your shares, your shares of Novus Common Stock and Novus Class B Common Stock will be voted as recommended by Novus’s board of directors. With respect to proposals for the special meeting of stockholders, that means: “FOR” the Business Combination Proposal, “FOR” each of the Charter Proposals, “FOR” the Equity Incentive Plan Proposal, “FOR” the NYSE Proposal and “FOR” the Adjournment Proposal.

•

You can virtually attend the special meeting and vote online. However, if your shares of Novus Common Stock are held in the name of your broker, bank or other nominee, you must get a proxy from the broker, bank or other nominee. That is the only way we can be sure that the broker, bank or nominee has not already voted your shares of Novus Common Stock.

Quorum and Vote Required for the Stockholder Proposals

A quorum of Novus’s stockholders is necessary to hold a valid meeting. A quorum will be present at the special meeting of stockholders if a majority of the Novus Common Stock and Novus Class B Common

TABLE OF CONTENTS

Stock outstanding and entitled to vote at the meeting is virtually represented in person or by proxy and, with respect to the separate vote by other Novus Class B Common Stock for other Charter Proposals if a majority of the shares of Novus Class B Common Stock outstanding and entitled to vote at the meeting is virtually represented in person or by proxy. Abstentions will count as present for the purposes of establishing a quorum.

The approval of the Business Combination Proposal requires the affirmative vote (virtually in person or by proxy) of the holders of a majority of the then outstanding shares of Novus Common Stock entitled to vote thereon at the special meeting. Accordingly, a Novus stockholder’s failure to vote by proxy or to vote online at the virtual special meeting of stockholders, an abstention from voting or a broker non-vote will have the same effect as a vote against this proposal.

The approval of the Charter Proposals requires the affirmative vote of the holders of a majority of the outstanding shares of the Novus Common Stock and Novus Class B Common Stock, voting together as a single class, and the affirmative vote of the holders of a majority of the Novus Class B Common Stock then outstanding, voting separately as a single class. Accordingly, a Novus stockholder’s failure to vote by proxy or to vote online at the virtual special meeting of stockholders, an abstention from voting or a broker non-vote will have the same effect as a vote against these proposals.

The approval of the Equity Incentive Plan Proposal, NYSE Proposal and Adjournment Proposal require the affirmative vote (virtually in person or by proxy) of the holders of a majority of the shares of Novus Common Stock that are voted at the special meeting of stockholders. Accordingly, a Novus stockholder’s failure to vote by proxy or to vote online at the virtual special meeting of stockholders, an abstention from voting, or a broker non-vote will have no effect on the outcome of any vote on these proposals.

Abstentions and Broker Non-Votes

Under the rules of various national and regional securities exchanges, your broker, bank or nominee cannot vote your shares with respect to non-discretionary matters unless you provide instructions on how to vote in accordance with the information and procedures provided to you by your broker, bank or nominee. Novus believes the proposals presented to its stockholders will be considered non-discretionary and therefore your broker, bank or nominee cannot vote your shares without your instruction. If you do not provide instructions with your proxy, your bank, broker or other nominee may deliver a proxy card expressly indicating that it is NOT voting your shares; this indication that a bank, broker or nominee is not voting your shares is referred to as a “broker non-vote.”

Abstentions and broker non-votes will be counted for purposes of determining the presence of a quorum at the special meeting of Novus’s stockholders. For purposes of approval, an abstention or failure to vote will have the same effect as a vote against each of the Business Combination Proposal, the individual Charter Proposals, and the NYSE Proposals and will have no effect on any of the other Stockholder Proposals.

Revocability of Proxies

If you have submitted a proxy to vote your shares and wish to change your vote, you may do so by delivering a later-dated, signed proxy card to Novus’s secretary, at 8556 Oakmont Lane, Indianapolis, IN 46260, prior to the date of the special meeting or by voting online at the virtual special meeting. Attendance at the special meeting alone will not change your vote. You also may revoke your proxy by sending a notice of revocation to Novus’s secretary at the above address.

Redemption Rights

Pursuant to the Existing Certificate of Incorporation, any holders of Public Shares may demand that such shares be redeemed in exchange for a pro rata share of the aggregate amount on deposit in the Trust Account, which holds the proceeds of the IPO and a concurrent private placement of warrants to the Founders, including any amounts representing interest earned on the Trust Account, less any interest for any income and other taxes payable, calculated as of two business days prior to the consummation of the

109

TABLE OF CONTENTS

Business Combination, provided that such stockholders follow the specific procedures for redemption set forth in this proxy statement/prospectus relating to the stockholder vote on the Business Combination. If demand is properly made and the Business Combination is consummated, these shares, immediately prior to the Business Combination, will cease to be outstanding and will represent only the right to receive such pro rata share of the aggregate amount on deposit in the Trust Account. For illustrative purposes, based on funds in the Trust Account of approximately $287.5 million on [*], 2022, the estimated per Public Share redemption price would have been approximately $10.00.

Redemption rights are not available to holders of Novus Warrants in connection with the Business Combination.

In order to exercise your redemption rights, you must, prior to 4:30 p.m., Eastern time, on , 2022 (two business days before the special meeting), both:

•

Submit a request in writing that Novus redeem your Public Shares for cash to Continental Stock Transfer & Trust Company, Novus’s transfer agent, at the following address:

Continental Stock Transfer & Trust Company
One State Street Plaza, 30th Floor
New York, New York 10004
Attention: Mark Zimkind
E-mail: mzimkind@continentalstock.com

•

Deliver your Public Shares either physically or electronically through DTC to Novus’s transfer agent. Stockholders seeking to exercise their redemption rights and opting to deliver physical certificates should allot sufficient time to obtain physical certificates from the transfer agent. It is Novus’s understanding that stockholders should generally allot at least one week to obtain physical certificates from the transfer agent. However, Novus does not have any control over this process and it may take longer than one week.

•

Stockholders who hold their shares in street name will have to coordinate with their bank, broker or other nominee to have the shares certificated or delivered electronically. If you do not submit a written request and deliver your Public Shares as described above, your shares will not be redeemed.

Each redemption of Public Shares by the Public Stockholders will decrease the amount in the Trust Account. In no event, however, will Novus redeem Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001 upon completion of the Business Combination.

Prior to exercising redemption rights, stockholders should verify the market price of their Novus Common Stock as they may receive higher proceeds from the sale of their Novus Common Stock in the public market than from exercising their redemption rights if the market price per share is higher than the redemption price. Novus cannot assure you that you will be able to sell your shares of Novus Common Stock in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in Novus Common Stock when you wish to sell your shares.

If you exercise your redemption rights, your shares of Novus Common Stock will cease to be outstanding immediately prior to the Business Combination and will only represent the right to receive a pro rata share of the aggregate amount on deposit in the Trust Account, including any amounts representing interest earned on the Trust Account, less taxes payable. You will no longer own those shares. You will be entitled to receive cash for these shares only if you properly demand redemption.

Appraisal or Dissenters’ Rights

No appraisal or dissenters’ rights are available to holders of shares of Novus Common Stock, Novus Class B Common Stock or Novus Warrants in connection with the Business Combination.

PROPOSAL NO. 1 — THE BUSINESS COMBINATION PROPOSAL

THE BUSINESS COMBINATION

The Background of the Business Combination

Novus is a blank check company formed as a corporation in Delaware on September 29, 2020 for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities.

On February 8, 2021, Novus completed its initial public offering. Prior to the consummation of the IPO, neither Novus, nor anyone on its behalf, contacted any prospective target business or had any discussions, formal or otherwise, with respect to a transaction with Novus.

From the date of the IPO through the signing of the mutually exclusive letter of intent with Energy Vault on April 14, 2021, Novus’s management and board members collectively reviewed self-generated ideas; generated leads through a marketing campaign utilizing LinkedIn; and were contacted directly and indirectly by more than 100 firms including, but not limited to, investment banks, private equity firms, law firms, business brokers, venture capital firms, smart technology innovation market participants and high technology industry participants and personal and professional contacts with respect to business combination ideas, identified several possible target businesses and held discussions with respect to potential transactions. In addition, during that period, Robert J. Laikin, Chief Executive Officer and Larry M. Paulson, Chairman of Novus, and board members of Novus, identified and evaluated more than 100 potential transactions with businesses addressing various markets at the forefront of renewable energy, lunar logistics artificial intelligence, online marketplaces, vertical farming, energy storage, oil and gas, electric aircraft and vessel manufacturing, beverage branding, fintech, 3D printing, disruptive logistics, software technology, medical hardware manufacturing, electric vehicle charging stations, online gaming, wireless distribution, autonomy software, recycling, information data development, robotic manufacturing, online education, light detection and ranging, smart glass, mobile phone manufacturing, internet of things (IOT), and sustainable agricultural technology, referred to as AgTech, and others while conducting its initial technical and financial diligence of Energy Vault.

Representatives of Novus signed non-disclosure agreements and engaged in due diligence, review of information and held discussions with the senior executives and/or shareholders of numerous potential acquisition targets, including Energy Vault. The potential valuations discussed for these potential targets ranged from $100 million up to $2.5 billion and these target businesses operated in a variety of industries.

The decision to pursue a business combination with Energy Vault rather than a transaction with an alternative acquisition target were generally due to Novus’s management and board of directors view that Energy Vault’s innovative and disruptive model presents the potential to disrupt the existing markets for energy storage; Energy Vault’s strong institutional and strategic investors, including SoftBank and strategic partner, Enel Green Energy (the world’s largest independent power produced in the renewable energy space), as well as Saudi Aramco Energy Venture; Energy Vault’s working with leading industry partners such as Cemex; Energy Vault’s solutions being environmentally sustainable; Energy Vault’s significant market opportunity in the rapidly growing renewable energy market; the experienced management team at Energy Vault who worked in the past with leading companies, including Danaher, British Petroleum, Foster-Wheeler, RWE, Stem, SpaceX, Canadian Solar; large total addressable market opportunity for Energy Vault’s solution as the transition from fossil fuels to renewable energy accelerates over the next 20 to 30 years; and Novus’s discussions with certain of Energy Vault’s partners, investors and customers.

In late January 2021, Mr. Laikin was introduced by Alan Schwartz of Guggenheim to the founders of Helena Special Investments LLC (“Helena”), Sam Feinburg and Henry Elkus. The introduction was made to Mr. Laikin in his capacity of a private investor and not as a representative of Novus. Helena is a company that identifies global problems, performs due diligence on potential solutions, and executes those solutions in the form of tangible projects and investment.

A call took place on February 1, 2021 among Messrs. Laikin, Elkus and Feinburg. During this call Mr. Laikin was solicited to invest in a future Helena $100 million fund and was also offered the opportunity

112

TABLE OF CONTENTS

to invest in a current investment in which Helena had committed funds through Helena SPV. Helena SPV had committed to invest in Energy Vault. Mr. Laikin was given a general, high-level explanation of Energy Vault. Based on the discussions and vision of Messrs. Elkus and Feinburg about their fund and areas of expertise, Mr. Laikin asked for an allocation of $250,000 in the Helena SPV. Helena explained to Mr. Laikin that Helena had invested in three companies, Energy Vault being the third investment, and each investment has been done through a special purpose vehicle whereby Helena receives a profit interests based on results. Mr. Laikin suggested that Helena speak with Messrs. Paulson and Foster, for the purpose of personally investing in the Helena SPV. Such introductions were made in their capacity as private investors and not as representatives of Novus. Helena advised Mr. Laikin that the investment was over-subscribed but Helena would make room for Messrs. Laikin, Paulson and Foster.

On February 3, 2021, Messrs. Paulson and Foster had a conversation with Messrs. Elkus and Feinburg and, based on Mr. Laikin’s interest in the SPV, also asked for allocation of $250,000 each in the Helena SPV. Messrs. Laikin, Paulson and Foster were impressed with the qualifications and processes of Messrs. Elkus and Feinburg.

On February 3, 2021, Mr. Laikin made an investment of $250,000 in Helena SPV. Messrs. Laikin, Paulson and Foster signed an NDA with Helena on February 3, 2021. Messrs. Paulson and Foster committed to make investments into the Helena SPV on February 4, 2021 and executed subscription agreements with Helena SPV on February 8, 2021. None of Messrs. Laikin, Paulson or Foster are beneficial owners of the securities of Energy Vault held by the Helena SPV since they do not have or share voting or dispositive power over the Energy Vault securities held by Helena SPV. In connection with making a passive investment in the Helena SPV, Messrs. Laikin, Paulson and Foster spoke only with representatives of Helena and did not communicate with representatives of Energy Vault. At the time of their investments in SPV, Energy Vault was not a contemplated target for Novus.

The Novus board of directors also concluded that the fair market value of Energy Vault was equal to at least 80% of the funds held in the Trust Account. In making such determination, Novus’s board of directors considered, among other things, the implied valuation of Energy Vault based on the implied valuation reference ranges of Energy Vault reviewed by Cassel Salpeter with the Special Committee and the price to be paid by the Subscribers in the PIPE.

Prior to the market open on September 9, 2021, Novus and Energy Vault issued a joint press release announcing the execution of the Business Combination Agreement and Novus filed with the SEC a Current Report on Form 8-K announcing the execution of the Business Combination Agreement.

Novus’s Board of Directors’ Reasons for the Approval of the Business Combination

As described under “— The Background of the Business Combination” above, Novus’s board of directors, in evaluating the Business Combination, consulted with Novus’s management and financial and legal advisors. In reaching its unanimous resolution that (i) the terms and conditions of the Business Combination Agreement, including the transactions contemplated therein, are advisable, fair to, and in the best interests of Novus and its stockholders and (ii) to recommend that the Novus stockholders adopt and approve the Business Combination Agreement and approve the transactions contemplated therein, Novus’s board of directors considered a range of factors, including, but not limited to, the factors discussed below. In light of the number and wide variety of factors considered in connection with its evaluation of the proposed business combination, the Novus board of directors did not consider it practicable to, and did not attempt to, quantify or otherwise assign relative weights to the specific factors that it considered in reaching its

116

TABLE OF CONTENTS

determination and supporting its decision. The Novus board of directors viewed its decision as being based on all of the information available and the factors presented to and considered by it. In addition, individual directors may have given different weight to different factors.

This explanation of Novus’s reasons for the combination and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under the section titled “Cautionary Note Regarding Forward-Looking Statements.”

•

Innovative and Disruptive Business Model. Novus’s management and board of directors believes that Energy Vault’s technologies offer a competitive approach to address a global need for renewable energy storage and potentially disrupt the existing markets for energy storage due to lower levelized costs to operate and higher efficiency than other mechanical and thermodynamic renewable energy storage technologies, sustainability, scalability and the flexibility resulting from its modular solutions;

•

Significant Market Opportunity. Novus’s management and board of directors considered the fact that the renewable energy market is growing rapidly. The renewable energy market represented is projected to grow to 90% of total power generation by 2050 according to a recent report. Additionally, global grid-scale energy storage projects are projected by more than six times in capacity over the next ten years according to a U.S. Department of Energy report;

•

Environmentally Sustainable Solution. Novus’s management and board of directors believes that there is significant momentum among corporations, governments and society for sustainable renewable energy solutions and significant demand for investments in this area;

•

Significant Growth Potential. Energy Vault has been in discussions with numerous potential customers and suppliers which Novus’s management and board of directors believes creates the potential for Energy Vault to scale;

•

Due Diligence. Novus’s management and board of directors conducted due diligence examinations of Energy Vault, including a technical assessment of Energy Vault’s technology, and held discussions with Energy Vault’s management and Novus’s financial and legal advisors concerning Novus’s due diligence examination of Energy Vault;

•

Financial Condition. The Novus board of directors also considered factors such as Energy Vault’s outlook, financial plan and capital structure, as well as valuations using projected multiples for Energy Vault on a Combined Company basis (see “— Certain Energy Vault Projected Financial Information”);

•

Strong Strategic Partners and Institutional Investors. In June 2020, Saudi Aramco Energy Venture announced that it made a strategic investment in Energy Vault. Additionally institutional investors SoftBank and Helena have made investments in Energy Vault which, in the aggregate represent approximately 29.9% of Energy Vault’s capital stock outstanding prior to the consummation of the Business Combination;

•

Other Alternatives. The Novus board of directors believes, after a thorough review of other business combination opportunities reasonably available to Novus, that the Business Combination represents the best potential business combination for Novus and the most attractive opportunity for Novus based upon the process utilized to evaluate and assess other potential combination targets, and Novus’s board of directors’ belief that such process has not presented a better alternative; and

•

Negotiated Transaction. The financial and other terms of the Business Combination Agreement, which terms and conditions are reasonable, were the product of arm’s length negotiations between Novus and Energy Vault.

117

Early-stage Pre-commercialization Company. Energy Vault’s status as an early-stage, pre-commercialization company, and the risk that it may not be able to execute on its business plan;

•

Macro-economic Risks. Macro-economic uncertainty and the effects it could have on the Combined Company’s operating results;

•

Redemption Risk. The potential that a significant number of Novus’s stockholders elect to redeem their shares prior to the consummation of the Business Combination and pursuant to Novus’s existing charter, which would potentially make the Business Combination more difficult or impossible to complete, and/or reduce the amount of cash available to the Combined Company following the Closing;

•

On September 6, 2021, Cassel Salpeter & Co., LLC (“Cassel Salpeter”) rendered its oral opinion to the special committee of the board of directors of Novus (which was confirmed in writing by delivery of Cassel Salpeter’s written opinion dated such date), as to whether, as of the date of such opinion, the aggregate closing consideration to be issued by Novus in connection with the Business Combination pursuant to the Business Combination Agreement was fair, from a financial point of view, to Novus

undertaken and other matters considered by Cassel Salpeter in preparing its opinion. However, neither Cassel Salpeter’s written opinion nor the summary of its opinion and the related analyses set forth in this proxy statement/prospectus are intended to be, and do not constitute, advice or a recommendation to any stockholder as to how such stockholder should act or vote with respect to any matter relating to the proposed Business Combination or otherwise, including, without limitation, whether any such stockholder should redeem their shares or whether any party should participate in the PIPE.

The opinion was addressed to the special committee of the board of directors of Novus for the use and benefit of the members of the special committee of the board of directors of Novus (in their capacities as such) and, as requested by the special committee of the board of directors of Novus , for the use and benefit of the members of the Novus Board (in their capacities as such) in connection with the special committee of the board of directors of Novus ‘s and, as applicable, the Novus Board’s evaluation of the Business Combination. Cassel Salpeter’s opinion was just one of the several factors the Novus Committee and the Novus Board took into account in making their determinations with respect to the Business Combination, including those described elsewhere in this proxy statement/prospectus.

Cassel Salpeter’s opinion only addressed whether, as of the date of the opinion, (i) the Aggregate Closing Consideration to be issued by Novus in connection with the Business Combination was fair, from a financial point of view, to Novus. It did not address any other terms, aspects, or implications of the Business Combination, the Agreement or any related or other transaction or agreement, including, without limitation, (i) the Registration Rights Agreement, the Lock-Up Agreements, the PIPE, the Sponsor Support Agreement or the Sponsor Restricted Stock Agreement, (ii) the Earn Out Shares, (iii) the fairness of the portion of the Aggregate Closing Consideration to be issued to holders of Energy Vault Common Stock or the fairness of the portion of the Aggregate Closing Consideration to be issued to holders of Series C Preferred Stock or holders of the Series C Interim Convertible Preferred Stock taken separately or relative to one another, (iv) the fairness of the Business Combination, or all or any portion of the Aggregate Closing Consideration, to any security holders of Novus, Energy Vault or any other person or any creditors or other constituencies of Novus, Energy Vault or any other person, (v) the appropriate capital structure of Novus or whether Novus should be issuing debt or equity securities or a combination of both in connection with the Business Combination, (vi) any capital raising or financing transaction contemplated by Novus or Energy Vault, including, without limitation, the PIPE, nor (vii) the fairness of the amount or nature, or any other aspect, of any compensation or consideration payable to or received by any officers, directors, or employees of any parties to the Business Combination, or any class of such persons, relative to the Aggregate Closing Consideration or otherwise. Cassel Salpeter did not express any view or opinion as to what the value of shares of Novus Common Stock or any other security of Novus actually would be when issued in connection with the Business Combination or the prices at which Novus Common Stock, Energy Vault Common Stock, Energy Vault Preferred Stock or any other security of Novus or Energy Vault may trade, be purchased or sold at any time.

Cassel Salpeter’s opinion did not address the relative merits of the Business Combination as compared to any alternative transaction or business strategy that might exist for Novus, or the merits of the underlying decision by the Novus Committee, the Novus Board or Novus to engage in or consummate the Business Combination. The financial and other terms of the Business Combination were determined pursuant to negotiations between the parties to the Agreement and were not determined by or pursuant to any recommendation from Cassel Salpeter. In addition, Cassel Salpeter was not authorized to, and did not, solicit indications of interest from third parties regarding a potential transaction involving Novus.

In arriving at its opinion, Cassel Salpeter made such reviews, analyses, and inquiries as it deemed necessary and appropriate under the circumstances. Among other things, Cassel Salpeter:

•

Reviewed a draft, dated September 6, 2021, of the Agreement.

•

Reviewed certain publicly available financial information and other data with respect to Novus and Energy Vault that Cassel Salpeter deemed relevant.

•

Reviewed certain other information and data with respect to Novus and Energy Vault made available to Cassel Salpeter by Novus and Energy Vault, including financial projections with respect to the future financial performance of Energy Vault prepared by management of Energy Vault as

119

TABLE OF CONTENTS

adjusted by management of Energy Vault (the “Projections”) and other internal financial information furnished to Cassel Salpeter by or on behalf of Novus and Energy Vault.

•

Considered and compared the financial and operating performance of Energy Vault with that of companies with publicly traded equity securities that Cassel Salpeter deemed relevant.

•

Discussed the business, operations, and prospects of Energy Vault and the proposed Business Combination with Novus’s and Energy Vault’s management and certain of Novus’s and Energy Vault’s representatives.

•

Conducted such other analyses and inquiries, and considered such other information and factors, as Cassel Salpeter deemed appropriate.

For purposes of its analyses and opinion, Cassel Salpeter, at the Novus Committee’s direction, assumed that (i) each share of Novus Class A Common Stock had a value equal to $10.00 per share (with such $10.00 value being based on the Novus’s initial public offering and Novus’s approximate cash per outstanding share of Novus Class A Common Stock (excluding, for the avoidance of doubt, the dilutive impact of outstanding shares of Novus Class B Common Stock or any warrants to purchase Novus Common Stock and notwithstanding the price at which shares of Energy Vault Series C Preferred Stock had been or would be issued)), (ii) the Aggregate Closing Consideration would consist of 114,760,000 shares of Novus Class A Common Stock, and (iii) the Aggregate Closing Consideration would have a value equal to $1,147,600,000. In addition, for purposes of its analyses and opinion, at the direction of the Novus Committee, Cassel Salpeter did not evaluate or take into account the Earn Out Shares.

In arriving at its opinion, Cassel Salpeter, with the Novus Committee’s consent, relied upon and assumed, without independently verifying, the accuracy and completeness of all of the financial and other information that was supplied or otherwise made available to Cassel Salpeter or available from public sources, and Cassel Salpeter further relied upon the assurances of Novus’s and Energy Vault’s management that they were not aware of any facts or circumstances that would have made any such information inaccurate or misleading. Cassel Salpeter also relied upon, without independent verification, the assessments of the managements of Novus and Energy Vault as to Energy Vault’s existing and future technology, products and services and the validity and marketability of, and risks associated with, such technology, products and services (including, without limitation, the development and marketing of such technology, products and services; and the life of all relevant patents and other intellectual and other property rights associated with such technology, products and services), and Cassel Salpeter assumed, at the Novus Committee’s direction, that there would be no developments with respect to any such matters that would adversely affect its analyses or opinion. Cassel Salpeter is not a legal, tax, accounting, environmental, regulatory, technology or science advisor, and Cassel Salpeter did not express any views or opinions as to any legal, tax, accounting, environmental, regulatory, technology or science matters relating to Novus, Energy Vault, the Business Combination, or otherwise. Cassel Salpeter understood and assumed that the Novus Committee had obtained or would obtain such advice as it deemed necessary or appropriate from qualified legal, tax, accounting, environmental, regulatory, technology, science and other professionals, that such advice was sound and reasonable and that the Novus Committee and Novus had acted or would act in accordance with such advice.

Energy Vault advised Cassel Salpeter, and Cassel Salpeter with the Novus Committee’s agreement assumed, that the Projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of Energy Vault with respect to the future financial performance of Energy Vault, and Cassel Salpeter assumed, at the Novus Committee’s direction, that the Projections provided a reasonable basis upon which to analyze and evaluate Energy Vault and form an opinion. At the Novus Committee’s direction, Cassel Salpeter used and relied upon Projections for purposes of its analyses and opinion. Cassel Salpeter expressed no view or opinion with respect to the Projections or the assumptions on which they were based. Cassel Salpeter did not evaluate the solvency or creditworthiness of Novus, Energy Vault or any other party to the Business Combination, the fair value of Novus, Energy Vault or any of their respective assets or liabilities, or whether Novus, Energy Vault or any other party to the Business Combination is paying or receiving reasonably equivalent value in connection with the Business Combination under any applicable foreign, state, or federal laws relating to bankruptcy, insolvency, fraudulent transfer, or similar matters, nor did Cassel Salpeter evaluate, in any way, the ability of Novus,

120

TABLE OF CONTENTS

Energy Vault or any other party to the Business Combination to pay its obligations when they come due. Cassel Salpeter did not physically inspect Novus’s or Energy Vault’s properties or facilities and did not make or obtain any evaluations or appraisals of Novus’s or Energy Vault’s assets or liabilities (including any contingent, derivative, or off-balance-sheet assets and liabilities). Cassel Salpeter did not attempt to confirm whether Novus and Energy Vault had good title to their respective assets. Cassel Salpeter’s role in reviewing any information was limited solely to performing such reviews as it deemed necessary to support its own advice and analysis and was not on behalf of the Novus Committee, the Novus Board, Novus, or any other party.

Cassel Salpeter assumed, with the Novus Committee’s consent, that the Business Combination would be consummated in a manner that complies in all respects with applicable foreign, federal, state, and local laws, rules, and regulations and that, in the course of obtaining any regulatory or third party consents, approvals, or agreements in connection with the Business Combination, no delay, limitation, restriction, or condition would be imposed that would have an adverse effect on Novus, Energy Vault or the Business Combination. Cassel Salpeter also assumed, with the Novus Committee’s consent, that the final executed form of the Agreement would not differ in any material respect from the draft Cassel Salpeter reviewed and that the Business Combination would be consummated on the terms set forth in the Agreement, without waiver, modification, or amendment of any term, condition, or agreement thereof that would be material to Cassel Salpeter’s analyses or opinion. Cassel Salpeter also assumed that the representations and warranties of the parties to the Agreement contained therein were true and correct and that each such party would perform all of the covenants and agreements to be performed by it under the Agreement. Cassel Salpeter offered no opinion as to the contractual terms of the Agreement or the likelihood that the conditions to the consummation of the Business Combination or the issuance of the Earn Out Shares set forth in the Agreement would be satisfied. The Novus Committee also advised Cassel Salpeter, and Cassel Salpeter assumed, that for U.S. federal tax income purposes the Business Combination would qualify as a reorganization within the meaning of Section 368 of the Internal Revenue Code of 1986, as amended.

Cassel Salpeter was not requested to, and did not, (a) initiate or participate in any discussions or negotiations with respect to the Business Combination, the securities, assets, businesses or operations of Novus, Energy Vault or any other party, or any alternatives to the Business Combination, (b) negotiate the terms of the Business Combination, or (c) advise the Novus Committee, the Novus Board, Novus or any other party with respect to alternatives to the Business Combination. Cassel Salpeter’s analyses and opinion were necessarily based upon market, economic, and other conditions as they existed on, and could be evaluated as of September 6, 2021, the date of its opinion. Accordingly, although subsequent developments could arise that would otherwise affect its opinion, Cassel Salpeter did not assume any obligation to update, review, or reaffirm its opinion to the Novus Committee or any other person or otherwise to comment on or consider events occurring or coming to Cassel Salpeter’s attention after the date of its opinion.

In connection with preparing its opinion, Cassel Salpeter performed a variety of financial analyses. The following is a summary of the material financial analyses performed by Cassel Salpeter in connection with the preparation of its opinion. It is not a complete description of all analyses underlying such opinion. The preparation of an opinion is a complex process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. As a consequence, neither Cassel Salpeter’s opinion nor the respective analyses underlying its opinion is readily susceptible to partial analysis or summary description. In arriving at its opinion, Cassel Salpeter assessed as a whole the results of all analyses undertaken by it with respect to the opinion. While it took into account the results of each analysis in reaching its overall conclusions, Cassel Salpeter did not make separate or quantifiable judgments regarding individual analyses and did not draw, in isolation, conclusions from or with regard to any individual analysis or factor. Therefore, Cassel Salpeter believes that the analyses underlying the opinion must be considered as a whole and that selecting portions of its analyses or the factors it considered, without considering all analyses and factors underlying the opinion collectively, could create a misleading or incomplete view of the analyses performed by Cassel Salpeter in preparing the opinion.

The implied valuation reference ranges indicated by Cassel Salpeter’s analyses are not necessarily indicative of actual values nor predictive of future results, which may be significantly more or less favorable than those suggested by such analyses. Much of the information used in, and accordingly the results of, Cassel Salpeter’s analyses are inherently subject to substantial uncertainty.

TABLE OF CONTENTS

Summary of Material Financial Analyses.

The following summary of the material financial analyses performed by Cassel Salpeter in connection with the preparation of its opinion includes information presented in tabular format. The tables alone do not constitute a complete description of these analyses. Considering the data in the tables below without considering the full narrative description of the analyses, as well as the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the financial analyses Cassel Salpeter performed.

Share prices for the selected companies used in the selected companies analysis described below were as of September 3, 2021. Estimates of future financial performance for Energy Vault were based on the Projections, and estimates of future financial performance for the selected companies listed below were based on publicly available research analyst estimates for those companies.

For purposes of its analyses, Cassel Salpeter reviewed a number of financial metrics, including the following:

•

EBITDA — generally the amount of the relevant company’s earnings before interest, taxes, depreciation and amortization for a specified time period.

•

Enterprise Value — generally the value as of a specified date of the relevant company’s outstanding equity securities (taking into account its options and other outstanding convertible securities) plus the value as of such date of its net debt (the value of its outstanding indebtedness, preferred stock and minority interests less the amount of cash on its balance sheet).

Assumed Value of Aggregate Closing Consideration. For purposes of its analyses, Cassel Salpeter, at the Novus Committee’s direction assumed that (i) each share of Novus Class A Common Stock had a value equal to $10.00 per share (with such $10.00 value being based on the Novus’s initial public offering and Novus’s approximate cash per outstanding share of Novus Class A Common Stock (excluding, for the avoidance of doubt, the dilutive impact of outstanding shares of Novus Class B Common Stock or any warrants to purchase Novus Common Stock and notwithstanding the price at which shares of Energy Vault Series C Preferred Stock had been or would be issued)), (ii) the Aggregate Closing Consideration would consist of 114,760,000 shares of Novus Class A Common Stock, and (iii) the Aggregate Closing Consideration would have a value equal to $1,147,600,000. In addition, for purposes of its analyses and opinion, at the direction of the Novus Committee, Cassel Salpeter did not evaluate or take into account the Earn Out Shares.

Discounted Cash Flows Analysis. Cassel Salpeter performed a discounted cash flow analysis of Energy Vault based on the Projections. In performing this analysis, Cassel Salpeter applied discount rates ranging from 27.0% to 31.0% and a terminal H-Model assuming 50.00% initial cash flow growth declining over a seven-year straight line period to perpetual growth rates ranging from 2.5% to 3.5%, in each case taking into account its experience and professional judgment. This analysis indicated an implied aggregate equity value reference range of approximately $922,358,000 to $1,279,458,000 for Energy Vault, as compared to the assumed value of the Aggregate Closing Consideration of $1,147,600,000.

Selected Companies Analysis. Cassel Salpeter considered certain financial data for Energy Vault and selected companies with publicly traded equity securities Cassel Salpeter deemed relevant.

The financial data reviewed included:

•

Enterprise value as multiple of estimated revenue for the year ending December 31, 2023, or “2023E Revenue.”

•

Enterprise value as multiple of estimated EBITDA for the year ending December 31, 2023, or “2023E EBITDA.”

•

Enterprise value as multiple of estimated EBITDA for the year ending December 31, 2024, or “2024E EBITDA.”

Taking into account the results of the selected companies analysis, Cassel Salpeter applied multiple ranges of 1.75x to 2.25x to Energy Vault’s estimated 2023E revenue, 8.0x to 10.0x to Energy Vault’s estimated 2023E EBITDA and 2.5x to 3.5x to Energy Vault’s estimated 2024E EBITDA, which resulted in an implied aggregate equity value reference range of approximately $1,013,958,000 to $1,293,458,000 for Energy Vault, as compared to the assumed value of the Aggregate Closing Consideration of $1,147,600,000.

None of the selected companies have characteristics identical to Energy Vault. An analysis of selected publicly traded companies is not mathematical; rather it involves complex considerations and judgments concerning differences in financial and operating characteristics of the selected companies and other factors that could affect the public trading values of the companies reviewed.

Other Matters Relating to Cassel Salpeter’s Opinion

As part of its investment banking business, Cassel Salpeter regularly is engaged in the evaluation of businesses and their securities in connection with mergers, acquisitions, corporate restructurings, private placements and other purposes. Cassel Salpeter is a recognized investment banking firm that has substantial experience in providing financial advice in connection with mergers, acquisitions, sales of companies, businesses and other assets and other transactions. Cassel Salpeter received a fee of $140,000 for rendering its opinion, no portion of which was contingent upon the completion of the Business Combination. In addition, Novus agreed to reimburse Cassel Salpeter for certain expenses incurred by it in connection with its engagement and to indemnify Cassel Salpeter and its related parties for certain liabilities that may arise out of its engagement or the rendering of its opinion. In accordance with Cassel Salpeter’s policies and procedures, a fairness committee of Cassel Salpeter was not required to, and did not, approve the issuance of Cassel Salpeter’s opinion.

Certain Unaudited Energy Vault Prospective Financial Information

Energy Vault provided Novus with its internally prepared forecasts for each of the years in the five-year period ending December 31, 2025. Energy Vault does not, as a matter of general practice, publicly disclose long-term forecasts or internal projections of its future performance, revenue, financial condition or other results. However, in connection with the proposed Business Combination, management of Energy Vault prepared the financial projections set forth below to present key elements of the forecasts to Novus and to the Energy Vault board. Energy Vault’s forecasts were prepared solely for internal use and not with a view toward public disclosure, U.S. GAAP, the published guidelines of the SEC regarding projections or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information.

The inclusion of financial projections in this proxy statement/prospectus should not be regarded as an indication that Energy Vault, its management, board of directors, or its affiliates, advisors or other

123

TABLE OF CONTENTS

representatives considered, or now considers, such financial projections necessarily to be predictive of actual future results or to support or fail to support your decision whether to vote for or against the Business Combination Proposal. No person has made or makes any representation or warranty to any Novus stockholder regarding the information included in these financial projections. The financial projections are not fact and should not be relied upon as being indicative of future results, and readers of this proxy statement/prospectus, including investors or stockholders, are cautioned not to place undue reliance on this information. You are cautioned not to rely on the projections in making a decision regarding the Business Combination, as the projections may be materially different than actual results. Energy Vault will not refer back to the financial projections in its future periodic reports filed under the Exchange Act.

The financial projections reflect numerous estimates and assumptions with respect to general business, economic, regulatory, market and financial conditions and other future events, as well as matters specific to Energy Vault’s business, all of which are difficult to predict and many of which are beyond Energy Vault’s and Novus’s control. As a result, there can be no assurance that the projected results will be realized or that actual results will not be materially lower than projected. Since the financial projections cover multiple years, such information by its nature becomes less reliable with each successive year. These financial projections are subjective in many respects and thus are susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. As such, the financial projections are forward looking statements that are inherently subject significant uncertainties and contingencies, many of which are beyond Energy Vault’s control. The various risks and uncertainties include those set forth in the “Risk Factors,” “Energy Vault Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Cautionary Note Regarding Forward-Looking Statements” sections of this proxy statement/prospectus, respectively

A summary of the financial projections is provided in this proxy statement/prospectus because they were made available to Novus and its board of directors in connection with their review of the proposed transaction.

EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE FEDERAL SECURITIES LAWS, BY INCLUDING IN THIS PROXY STATEMENT/PROSPECTUS A SUMMARY OF THE FINANCIAL PROJECTIONS FOR ENERGY VAULT, NOVUS UNDERTAKES NO OBLIGATIONS AND EXPRESSLY DISCLAIMS ANY RESPONSIBILITY TO UPDATE OR REVISE, OR PUBLICLY DISCLOSE ANY UPDATE OR REVISION TO, THESE FINANCIAL PROJECTIONS TO REFLECT CIRCUMSTANCES OR EVENTS, INCLUDING UNANTICIPATED EVENTS, THAT MAY HAVE OCCURRED OR THAT MAY OCCUR AFTER THE PREPARATION OF THESE FINANCIAL PROJECTIONS, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING THE FINANCIAL PROJECTIONS ARE SHOWN TO BE IN ERROR OR CHANGE.

The projections were prepared by, and are the responsibility of, Energy Vault’s management. Neither BDO USA, LLP, Energy Vault’s independent registered public accounting firm, nor Marcum LLP, Novus’s independent registered public accounting firm, has audited, reviewed, examined, compiled or otherwise applied procedures with respect to the accompanying prospective financial information presented herein and, accordingly, expresses no opinion or any other form of assurance on it. The report by BDO USA, LLP included in this proxy statement/prospectus relates to Energy Vault’s previously issued financial statements. It does not extend to the unaudited financial projections and should not be read as if it does.

The projections set out below assume the consummation of the Business Combination. As described above, Energy Vault’s ability to achieve these projections will depend upon a number of factors outside of its control. These factors include significant business, economic and competitive uncertainties and contingencies. Energy Vault developed these projections based upon assumptions with respect to future business decisions and conditions that are subject to change, including Energy Vault’s execution of its strategies and product development, as well as growth in the markets in which it currently operates and proposes to operate. As a result, Energy Vault’s actual results may materially vary from the projections set out below. See also “Cautionary Statement Regarding Forward-Looking Statements” and the risk factors set out in “Risk Factors — Risks Related to the Combined Company — If the Business Combination’s benefits do not meet the expectations of investors or securities analysts, the market price of Novus’s securities or, following the Closing, the Combined Company’s securities, may decline.”

124

TABLE OF CONTENTS

The key elements of the projections provided by management of Energy Vault to Novus are summarized in the table below, and took into account the assumptions and definitions discussed in the two paragraphs immediately following the table:

	Forecast Year Ended December 31,
	2021E			2022E			2023E			2024E			2025E
	(in millions)
Revenue		$	0		$	148		$	535		$	1,519		$	2,764
Adjusted EBITDA			(36)			(10)			102			366			662
Capital Expenditures			25			211			193			156			122
Cash Flow			(49)			(234)			(136)			21			247

Energy Vault’s management estimated that it would not recognize any revenue in the year ended December 31, 2021 based on its then-current outlook regarding the early stages of identified projects to potential customers. Energy Vault’s management estimates for revenue in the years ended December 31, 2022 and 2023 reflect revenues attributable to sales for identified projects to potential customers adjusted to reflect the probability that such customers’ projects commence and the customers enter into definitive agreements with Energy Vault and that the projects commence on schedule and that the associated revenue is recognized as expected. Energy Vault’s management estimates for revenue in the years ended December 31, 2024 and 2025 reflect revenues (a) attributable to sales to potential identified customers adjusted to reflect the probability that such customers’ projects commence and the customers enter into definitive agreements with Energy Vault and that the associated revenue is recognized as expected and (b) attributable to as-of-yet unknown customer agreements based on management’s estimates of the addressable market for Energy Vault’s products in those years. Energy Vault’s management estimates for revenue also incorporate sales prices based on management’s estimates for such prices. As forecasted, Energy Vault’s revenue in the years ended December 31, 2022, 2023, 2024 and 2025 is primarily attributable to the sale of its systems and the revenue from fees received for accepting waste to be used in the building of its mobile masses. Energy Vault’s estimates for Adjusted EBITDA are based on the difference between its revenue estimates and the forecasted expenses for such periods. Such forecasts for expenses reflect an increase in projected overhead costs based on increasing personnel costs that reflect Energy Vault’s expectations regarding business growth and the demands of being a public company and estimated investments in continued research and development activities. Energy Vault’s forecasts for capital expenditures reflect management’s estimates about the number and size of its systems that will be owned by Energy Vault and the costs of making machines to produce Energy Vault’s mobile masses for all projects.

Energy Vault defines Adjusted EBITDA, a non-GAAP financial measure, as revenue, less the sum of cost of goods sold and operating expenses, inclusive of selling, general and administrative expense and research and development expenses. Due to the forward-looking nature of these projections, reconciling such projections to GAAP measures is not practicable. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with GAAP, and may not be comparable to similarly titled measures used by other companies.

Interests of Novus’s Directors and Officers in the Business Combination

When you consider the recommendation of Novus’s board of directors in favor of approval of the Business Combination Proposal and the other Stockholder Proposals, you should keep in mind that certain of Novus’s directors and officers have interests in the Business Combination that are different from, in addition to, or in conflict with your interests as a stockholder or warrant holder. These interests include, among other things:

•

125

TABLE OF CONTENTS

NYSE on January [*], 2022, the Record Date for the special meeting of stockholders. Based on such market values, Novus’s board of directors and officers will have an unrealized gain of approximately $[*] million on their Novus securities;

•

Messrs. Robert J. Laikin, Chief Executive Officer, a director and a principal stockholder of Novus, Larry Paulson, Chairman of the Board and a principal stockholder of Novus, and Jeffrey Foster, a director of Novus, each purchased a non-controlling membership interest in Helena SPV for $250,000. Each such membership interest will equate to an indirect interest of 119,632 shares of Combined Company Common Stock. Based on the closing sale price of Novus Common Stock on the Record Date, each such individual’s membership interest have a value of $ [ ] and will have an unrealized gain on this investment of $[•] (based on the closing sale price of the Novus Common Stock of $[ ] as of the Record Date) .

•

Novus’s directors and officers and their affiliates have agreed to purchase an aggregate of 1,100,000 shares of Novus Common Stock in the PIPE at a purchase price of $10.00 per shares, which purchase will not occur if Novus does not complete the Business Combination;

•

Novus’s board of directors will not receive reimbursement for any out-of-pocket expenses incurred by them on Novus’s behalf incident to identifying, investigating and consummating a business combination to the extent such expenses exceed the amount not required to be retained in the Trust Account, unless a business combination is consummated;

•

the anticipated continuation of Larry Paulson, as a director of the Combined Company following the Closing;

•

Potential Actions to Secure Requisite Stockholder Approvals

In connection with the stockholder vote to approve the Business Combination, the Novus Initial Stockholders and Novus’s board of directors, officers, advisors or their affiliates may privately negotiate transactions to purchase shares of Novus Common Stock from stockholders who would have otherwise elected to have their shares redeemed in conjunction with the Business Combination for a per share pro rata portion of the Trust Account. None of the Founders or Novus’s board of directors, officers, advisors or their affiliates will make any such purchases when they are in possession of any material non-public information not disclosed to the seller of such shares. Such a purchase of shares may include a contractual acknowledgement that such stockholder, although still the record holder of the shares of Novus Common Stock is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights. In the event that the Founders or Novus’s board of directors, officers, advisors or their affiliates purchase shares in privately negotiated transactions from Public Stockholders who have already elected to exercise their redemption rights, such selling stockholders would be required to revoke their prior elections to redeem their shares. Any such privately negotiated purchases may be effected at purchase prices that are in excess of the per share pro rata portion of the Trust Account. The purpose of these purchases would be to increase the amount of cash available to Novus for use in the Business Combination.

Regulatory Approvals Required for the Business Combination

Under the HSR Act and related rules, certain transactions, including the Business Combination, may not be completed until notifications have been given and information is furnished to the Antitrust Division of the DOJ and the FTC and all statutory waiting period requirements have been satisfied. Completion of the Business Combination is subject to the expiration or earlier termination of the applicable waiting period under the HSR Act.

126

TABLE OF CONTENTS

At any time before or after the expiration of the statutory waiting periods under the HSR Act, the Antitrust Division of the DOJ and the FTC may take action under the antitrust laws, including seeking to enjoin the completion of the Business Combination, to rescind the Business Combination or to conditionally permit completion of the Business Combination subject to regulatory conditions or other remedies. In addition, non-U.S. regulatory bodies and U.S. state attorneys general could take action under other applicable regulatory laws as they deem necessary or desirable in the public interest, including, without limitation, seeking to enjoin or otherwise prevent the completion of the Business Combination or permitting completion subject to regulatory conditions. Private parties may also seek to take legal action under regulatory laws under some circumstances. There can be no assurance that a challenge to the Business Combination on antitrust grounds will not be made or, if such a challenge is made, that it would not be successful. Novus and Energy Vault are not aware of any other regulatory approvals in the United States required for the consummation of the Business Combination.

Accounting Treatment of the Business Combination

The Business Combination will be accounted for as a “reverse recapitalization” in accordance with GAAP. Under this method of accounting Novus will be treated as the “acquired” company for financial reporting purposes. This determination is primarily based on the fact that subsequent to the Business Combination, the stockholders of Energy Vault are expected to have a majority of the voting power of the Combined Company, Energy Vault will comprise all of the ongoing operations of the Combined Company, Energy Vault will comprise a majority of the governing body of the Combined Company, and Energy Vault’s senior management will comprise all of the senior management of the Combined Company. Accordingly, for accounting purposes, the Business Combination will be treated as the equivalent of Energy Vault issuing shares for the net assets of Novus, accompanied by a recapitalization. The net assets of Novus will be stated at historical costs. No goodwill or other intangible assets will be recorded. Operations prior to the Business Combination will be those of Energy Vault.

THE BUSINESS COMBINATION AGREEMENT

The following is a summary of the material terms of the Business Combination Agreement. A copy of the Business Combination Agreement is attached hereto as Annex A to this proxy statement/prospectus and is incorporated by reference into this proxy statement/prospectus. The Business Combination Agreement has been attached to this proxy statement/prospectus to provide you with information regarding its terms. It is not intended to provide any other factual information about Novus, Energy Vault or Merger Sub. The following description does not purport to be complete and is qualified in its entirety by reference to the Business Combination Agreement. You should refer to the full text of the Business Combination Agreement for details of the Business Combination and the terms and conditions of the Business Combination Agreement.

The Business Combination Agreement contains representations and warranties that Novus and Merger Sub, on the one hand, and Energy Vault, on the other hand, have made to one another as of specific dates. These representations and warranties have been made for the benefit of the other parties to the Business Combination Agreement and may be intended not as statements of fact but rather as a way of allocating the risk to one of the parties if those statements prove to be incorrect. In addition, the assertions embodied in the representations and warranties are qualified by information in confidential disclosure schedules exchanged by the parties in connection with signing the Business Combination Agreement. While Novus and Energy Vault do not believe that these disclosure schedules contain information required to be publicly disclosed under the applicable securities laws, other than information that has already been so disclosed, the disclosure schedules do contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the attached Business Combination Agreement. Accordingly, you should not rely on the representations and warranties as current characterizations of factual information about Novus or Energy Vault, because they were made as of specific dates, may be intended merely as a risk allocation mechanism between Novus, Merger Sub and Energy Vault and are modified by the disclosure schedules. The Disclosure Schedules are not publicly filed and are subject to a contractual standard of materiality different from that generally applicable to stockholders and were used for allocating risk among the parties as described above.

General

On September 8, 2021, Novus, Merger Sub and Energy Vault entered into the Business Combination Agreement, pursuant to which Novus and Energy Vault will enter into the Business Combination, including the Merger. The terms of the Business Combination Agreement, which contain customary representations and warranties, covenants, closing conditions, termination provisions and other terms relating to the Merger and the other transactions contemplated thereby, are summarized below.

Conversion of Securities

Immediately prior to the Effective Time, Energy Vault shall cause each share of Energy Vault Preferred Stock that is issued and outstanding immediately prior to the Effective Time to be automatically converted into a number of shares of Energy Vault Common Stock at the then effective conversion rate as calculated pursuant to Energy Vault’s amended and restated certificate of incorporation. All of the shares of Energy Vault Preferred Stock converted into shares of Energy Vault Common Stock shall no longer be outstanding and shall cease to exist, and each holder of Energy Vault Preferred Stock shall thereafter cease to have any rights with respect to such securities.

At the Effective Time, by virtue of the Merger and without any action on the part of Novus, Merger Sub, Energy Vault or the holders of any of Energy Vault’s securities:

•

Each Energy Vault Restricted Share will be cancelled and automatically converted into the right to receive the number of shares of Combined Company Common Stock equal to the Exchange Ratio; provided, however, that each share of Combined Company Common Stock issued in exchange for Energy Vault Restricted Shares shall be subject to the terms and conditions giving rise to a substantial risk of forfeiture that applied to such Energy Vault Restricted Shares immediately prior to the Effective Time to the extent consistent with the terms of such Energy Vault Restricted Shares;

•

128

TABLE OF CONTENTS

•

Each Energy Vault Option that is outstanding immediately prior to the Effective Time, whether vested or unvested, shall be assumed, converted and/or substituted into Exchanged Option equal to the product (rounded down to the nearest whole number) of (x) the number of shares of Energy Vault Common Stock subject to such Energy Vault Option immediately prior to the Effective Time and (y) the Exchange Ratio, and at an exercise price per share (rounded up to the nearest whole cent) equal to (A) the exercise price per share of such Energy Vault Option immediately prior to the Effective Time divided by (B) the Exchange Ratio; provided, however, that the exercise price and the number of shares of Combined Company Common Stock purchasable pursuant to the Exchanged Options shall be determined in a manner consistent with the requirements of Section 409A of the Code; provided, further, that in the case of any Exchanged Option to which Section 422 of the Code applies, the exercise price and the number of shares of Combined Company Common Stock purchasable pursuant to such option shall be determined in accordance with the foregoing, subject to such adjustments as are necessary in order to satisfy the requirements of Section 424(a) of the Code; provided, that, except as specifically provided above, following the Effective Time, each Exchanged Option shall continue to be governed by the same terms and conditions (including vesting and exercisability terms) as were applicable to the corresponding former Energy Vault Option immediately prior to the Effective Time;

•

Each Energy Vault RSU that is outstanding immediately prior to the Effective Time shall be assumed, converted and/or substituted by Novus into a Converted RSU Award. Each Converted RSU Award will represent the right to acquire that number of shares of Combined Company Common Stock equal to the product (rounded down to the nearest whole number) of (1) the number of shares of Energy Vault Common Stock subject to the Energy Vault RSU award immediately before the Effective Time and (2) the Exchange Ratio; provided, that, except as specifically provided above, following the Effective Time, each Converted RSU Award shall continue to be governed by the same terms and conditions (including vesting terms) as were applicable to the corresponding former Energy Vault RSU award immediately prior to the Effective Time; and

•

Additionally, at the Closing, an aggregate of approximately 15,000,000 shares of Novus common stock will be issued in connection with the PIPE.

Closing; Effective Time

The Merger is to become effective by the filing of a certificate of merger with the Secretary of State of the State of Delaware, in such form as is required by, and executed in accordance with, the relevant provisions of the DGCL and mutually agreed by the parties, and will be effective as of the Effective Time. The parties will hold the Closing immediately prior to such filing of a certificate of merger, on the Closing Date.

TABLE OF CONTENTS

CERTAIN AGREEMENTS RELATED TO THE BUSINESS COMBINATION

This section describes the material provisions of certain additional agreements entered into or to be entered into pursuant to or in connection with the transactions contemplated by the Business Combination Agreement, which are referred to as the “Related Agreements,” but does not purport to describe all of the terms thereof. The descriptions below are qualified by reference to the actual text of these agreements. You are encouraged to read the Related Agreements in their entirety.

Registration Rights Agreement

In connection with the Closing, the Reg Rights Holders will enter into Registration Rights Agreement. Pursuant to the Registration Rights Agreement, Novus will agree that, within the later of 20 business days and 30 calendar days after the closing of the Business Combination, Novus will file with the SEC (at Novus’s sole cost and expense) the Resale Registration Statement, and Novus shall use commercially reasonable efforts to have the Resale Registration Statement declared effective as soon as practicable after the filing thereof. In certain circumstances, the New Holders can demand up to three underwritten offerings, and all of the Reg Rights Holders will be entitled to piggyback registration rights.

Lock-Up Agreements

In connection with the Closing, the Founders and certain stockholders of Energy Vault will agree, subject to certain exceptions, not to (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, and the rules and regulations of the SEC promulgated thereunder, the Lock-up Shares, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any of the Lock-up Shares, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise or (iii) publicly announce any intention to effect any transaction specified in clause (i) or (ii). The Lock-Up Period shall terminate upon the earlier of (i) with respect to 50% of the Lock-Up Shares, 180 days after the Closing and (ii) with respect to the remaining 50% of the Lock-Up Shares, one year after the Closing; provided however that the Lock-Up Period shall terminate 180 days after the Closing with respect to the Private Warrants and the shares of Combined Company Common Stock issuable upon exercise of the Private Warrants.

Sponsor Restricted Stock Agreement

(a)

(b)

808,594 Founder Shares (approximately 11.125% of the Founder Shares) shall be released upon the date on which (x) the closing price of the Novus Common Stock (as adjusted for share splits, share capitalizations, reorganizations, recapitalizations and the like) exceeds $15.00 per share for any 20 trading days within a 30-trading day period occurring from the announcement of the PIPE through the thirty-six (36) month anniversary of the Closing Date or (ii) the closing of a sale, merger, the remaining Lock-Up Shares liquidation, or exchange offer transaction after the closing date of the Business Combination which results in the stockholders of the Combined Company having the

140

TABLE OF CONTENTS

right to exchange their shares of Novus Common Stock for cash, securities or other property having a value of at least $15.00 per share.

(c)

$71,875,000 = 25% the aggregate dollar amount of cash redeemed from the Trust Account in excess of $25,000,000 (based on $96,875,000 total redeemed from the Trust Account)

$71,875,000/$287,500,000 = 25% (45.0% of 75% of the Founder Shares impacted negatively by 25%, which is the Forfeiture Percentage).

45.0% of the Founder Shares would be reduced by the Forfeiture Percentage of 25% (i.e., 11.25% of the Founder Shares would be forfeited).

Stockholder Support Agreement

On September 8, 2021, Energy Vault and certain stockholders of Energy Vault entered into the Stockholder Support Agreement pursuant to which such stockholders agreed to vote all of their shares of Energy Vault Common Stock and Energy Vault Preferred Stock in favor of the approval and adoption of the Proposed Transactions. Additionally, such stockholders have agreed, among other things, not to (a) transfer any of their shares of Energy Vault Common Stock and Energy Vault Preferred Stock (or enter into any arrangement with respect thereto), subject to certain customary exceptions or (b) enter into any voting arrangement that is inconsistent with the Stockholder Support Agreement.

Sponsor Support Agreement

On September 8, 2021, Novus, Energy Vault and the Founders entered into the Sponsor Support Agreement pursuant to which the Founders agreed to vote all of their shares of Novus Common Stock in favor of the approval and adoption of the Proposed Transactions. Additionally, such Founders have agreed, among other things, not to (a) transfer any of their shares of Novus Common Stock or Founder Shares (or enter into any arrangement with respect thereto), subject to certain customary exceptions, (b) enter into any voting arrangement that is inconsistent with the Sponsor Support Agreement or (c) exercise their redemption rights in connection with the Merger.

Subscription Agreements

In connection with the execution of the Business Combination Agreement, on September 8, 2021, Novus entered into separate Subscription Agreements with the Subscribers, pursuant to which the Subscribers agreed to purchase, and Novus agreed to sell to the Subscribers the PIPE Shares for a purchase price of $10.00 per share and an aggregate purchase price of $100,000,050 in the PIPE. In December 2021, Novus executed an additional Subscription Agreement with Korea Zinc Co., Ltd. (“Korea Zinc”) for the sale

141

TABLE OF CONTENTS

of an additional 5,000,000 shares of Novus Common Stock at a price of $10.00 per share for additional gross proceeds of $50.0 million in the PIPE. The Subscribers include Palantir Technologies Inc. (“Palantir”) who has agreed to invest $8.5 million in the PIPE. On September 3, 2021, Palantir and Energy Vault entered into an agreement (the “Software Agreement”) under which Energy Vault has agreed to purchase a Palantir Foundry cloud subscription (which provides advanced data analytics capability), including support services, updates and related professional services, from Palantir for $7.5 million payable over a term of two and a half years, beginning on December 1, 2021. Energy Vault may terminate the Software Agreement by giving written notice to Palantir within 20 business days of (a) the final expiration of termination of the Subscription Agreement with Palantir before the consummation of such agreement or (b) the failure of the Business Combination to close for any reason. In the event of a termination, Energy Vault shall only owe fees incurred under the Software Agreement before the effective date of termination and any fees relating to infrastructure costs incurred before the effective date of termination. On December 29, 2021, Energy Vault and Sun Metals Corporation Pty. Ltd. (“Sun Metals”), a wholly owned subsidiary of Korea Zinc, entered into a non-binding strategic partnership agreement for renewable energy storage. The partnership supports Korea Zinc’s strategy to decarbonize their refining and smelting operations focused initially under Sun Metals.

The closing of the sale of the PIPE Shares pursuant to the Subscription Agreements is contingent upon, among other customary closing conditions, the concurrent consummation of the Business Combination. The purpose of the PIPE is to raise additional capital for use by the Combined Company following the Closing.

Pursuant to the Subscription Agreements, Novus agreed that, within the later of 20 business days and 30 calendar days after the consummation of the Business Combination, Novus will file with the SEC (at Novus’s sole cost and expense) the PIPE Resale Registration Statement, and Novus shall use its commercially reasonable efforts to have the PIPE Resale Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the 60th calendar day (or 120th calendar day if the SEC notifies Novus that it will “review” the PIPE Resale Registration Statement) following the Closing and (ii) the 10th business day after the date Novus is notified (orally or in writing, whichever is earlier) by the SEC that the PIPE Resale Registration Statement will not be “reviewed” or will not be subject to further review.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS OF THE REDEMPTION AND
THE BUSINESS COMBINATION

The following is a discussion of certain U.S. federal income tax consequences for (i) holders of Novus Common Stock that elect to have their Novus Common Stock redeemed for cash if the Business Combination is completed, and (ii) solely to the extent specifically set forth herein, the exchange of Energy Vault Common Stock for Novus Common Stock by holders of Energy Vault Common Stock in the Business Combination. This discussion applies only to shares of Novus Common Stock or Energy Vault Common Stock held as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment). Further, with respect to the redemption of Novus Common Stock, the discussion is applicable only to holders who purchased Novus Common Stock in the IPO. Holders of Energy Vault Common Stock should consult their own tax advisors concerning the U.S. federal, state, local, foreign, and other tax consequences of the Business Combination.

This discussion does not address all U.S. federal income tax consequences that may be relevant to your particular circumstances. In addition, it does not address consequences relevant to holders subject to special rules, including, without limitation:

•

U.S. expatriates and former citizens or long-term residents of the United States;

•

persons subject to the alternative minimum tax;

•

persons holding Novus Common Stock or Energy Vault Common Stock as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated transaction;

•

banks, insurance companies and other financial institutions;

•

brokers, dealers or traders in securities;

•

“controlled foreign corporations,” “passive foreign investment companies” and corporations that accumulate earnings to avoid U.S. federal income tax;

•

partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes (and investors therein);

•

persons that acquired Novus Common Stock or Energy Vault Common Stock through the exercise of an option or otherwise as compensation;

•

persons that actually or constructively own 5% or more of Novus Common Stock or Energy Vault Common Stock by vote or value;

•

traders in securities that use the mark-to-market method of accounting for U.S. federal income tax purposes;

•

tax-exempt organizations or governmental organizations;

•

persons subject to special tax accounting rules as a result of any item of gross income being taken into account in an applicable financial statement;

•

U.S. holders (as defined below) whose functional currency is not the U.S. dollar;

•

mutual funds, regulated investment companies (RICs) or real estate investment trusts (REITs);

•

tax-qualified retirement plans; and

•

“qualified foreign pension funds” as defined in Section 897(l)(2) of the Code and entities all of the interests of which are held by qualified foreign pension funds.

If you are a partnership (or other pass-through entity) for U.S. federal income tax purposes, the tax treatment of your partners (or other owners) will generally depend on the status of the partners, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships (or other pass-through entities) and the partners (or other owners) in such partnerships (or such other pass-through entities) should consult their own tax advisors regarding the U.S. federal income tax consequences to them relating to the matters discussed below.

143

TABLE OF CONTENTS

For purposes of this discussion, a “U.S. holder” is a beneficial owner of shares of Novus Common Stock or Energy Vault Common Stock that is, for U.S. federal income tax purposes:

•

an individual who is a citizen or resident of the United States,

•

a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) organized in or under the laws of the United States, any state thereof or the District of Columbia,

•

an estate, the income of which is subject to U.S. federal income tax regardless of its source, or

•

an entity treated as a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code) or (2) was in existence on August 20, 1996 and has a valid election in effect under applicable Treasury regulations to be treated as a United States person for U.S. federal income tax purposes.

Also, for purposes of this discussion, a “Non-U.S. holder” is any beneficial owner of Novus Common Stock or Energy Vault Common Stock who or that is neither a U.S. holder nor an entity classified as a partnership for U.S. federal income tax purposes.

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Certain U.S. Federal Income Tax Considerations of the Redemption to the Holders of Novus Common Stock

The following does not purport to be a complete analysis of all potential tax effects stemming from the completion of the Business Combination that are associated with certain redemptions of Novus Common Stock. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the Code, Treasury regulations promulgated thereunder, judicial decisions and published rulings and administrative pronouncements of the Internal Revenue Service (“IRS”), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect holders to which this section applies and could affect the accuracy of the statements herein. Novus has not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance that the IRS or a court will not take a contrary position to that regarding tax consequences discussed below.

Holders of Novus Common Stock who do not exercise their redemption rights will not be selling, exchanging, or otherwise transferring their Novus Common Stock as described in this section.

U.S. Holders

Redemption of Novus Common Stock. In the event that a U.S. holder’s Novus Common Stock is redeemed pursuant to the redemption provisions described in the section titled “The Special Meeting of Novus’s Stockholders—Redemption Rights,” the treatment of the transaction for U.S. federal income tax purposes will depend on whether the redemption qualifies as a sale of the Novus Common Stock under Section 302 of the Code. If the redemption qualifies as a sale of the Novus Common Stock, the U.S. holder will be treated as described under “— U.S. Holders — Gain or Loss on Redemption Treated as a Sale of Novus Common Stock” below. If the redemption does not qualify as a sale of the Novus Common Stock, the U.S. holder will be treated as receiving a corporate distribution with the tax consequences described below under “— U.S. Holders — Taxation of Redemption Treated as a Distribution.”

Whether a redemption qualifies for sale treatment will depend largely on whether the U.S. holder owns any of Novus’s stock following the redemption (including any stock treated as constructively owned by the U.S. holder as a result of owning warrants or by attribution from certain related individuals and entities), and if so, the total number of shares of Novus’s stock held by the U.S. holder both before and after the redemption (including any stock constructively treated as owned by the U.S. holder as a result of owning

144

TABLE OF CONTENTS

warrants or by attribution from certain related individuals and entities) relative to all of Novus’s shares outstanding both before and after the redemption. The redemption of Novus Common Stock generally will be treated as a sale of the Novus Common Stock (rather than as a corporate distribution) if the redemption (i) is “substantially disproportionate” with respect to the U.S. holder, (ii) results in a “complete termination” of the U.S. holder’s interest in us or (iii) is “not essentially equivalent to a dividend” with respect to the U.S. holder. These tests are explained more fully below.

In determining whether any of the foregoing tests are satisfied, a U.S. holder takes into account not only stock actually owned by the U.S. holder, but also shares of our stock that are constructively owned by such holder. A U.S. holder may constructively own, in addition to stock owned directly, stock owned by certain related individuals and entities in which the U.S. holder has an interest or that have an interest in such U.S. holder, as well as any stock that the U.S. holder has a right to acquire by exercise of an option, which would generally include Novus Common Stock that could be acquired pursuant to the exercise of the warrants. Moreover, any Novus stock that a U.S. holder directly or constructively acquires pursuant to the Business Combination generally should be included in determining the U.S. federal income tax treatment of the redemption.

In order to meet the substantially disproportionate test, the percentage of Novus’s outstanding voting stock actually and constructively owned by the U.S. holder immediately following the redemption of Novus Common Stock must, among other requirements, be (i) less than 80% of the percentage of Novus’s outstanding voting stock actually and constructively owned by such U.S. holder immediately before the redemption (taking into account both redemptions by other holders of Novus Common Stock and the shares of Novus Common Stock to be issued pursuant to the Business Combination), and (ii) less than 50% of Novus’s total combined voting power. There will be a complete termination of a U.S. holder’s interest in Novus if either (i) all of the shares of our capital stock actually and constructively owned by the U.S. holder are redeemed or (ii) all of the shares of our capital stock actually owned by the U.S. holder are redeemed, the U.S. holder is eligible to waive, and effectively waives in accordance with specific rules, the attribution of stock owned by certain family members and the U.S. holder does not constructively own any other stock. The redemption of Novus Common Stock will not be essentially equivalent to a dividend if a U.S. holder’s redemption results in a “meaningful reduction” of the U.S. holder’s proportionate interest in Novus. Whether the redemption will result in a meaningful reduction in a U.S. holder’s proportionate interest in Novus will depend on the particular facts and circumstances. However, the IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a small minority stockholder in a publicly held corporation who exercises no control over corporate affairs may constitute such a “meaningful reduction.” A U.S. holder should consult with its own tax advisors as to the tax consequences of a redemption.

If none of the foregoing tests is satisfied, then the redemption will be treated as a corporate distribution, and the tax effects will be as described under “— U.S. Holders — Taxation of Redemption Treated as a Distribution” below. After the application of those rules, any remaining tax basis of the U.S. holder in the redeemed Novus Common Stock will be added to the U.S. holder’s adjusted tax basis in its remaining stock, or, if it has none, to the U.S. holder’s adjusted tax basis in its warrants or possibly in other stock constructively owned by it.

Gain or Loss on Redemption Treated as a Sale of Novus Common Stock. If the redemption qualifies as a sale of Novus Common Stock, a U.S. holder generally will recognize capital gain or loss in an amount equal to the difference between the amount realized in the redemption and the U.S. holder’s adjusted tax basis in its redeemed Novus Common Stock. The amount realized is the sum of the amount of cash and the fair market value of any property received, and a U.S. holder’s adjusted tax basis in its Novus Common Stock generally will equal the U.S. holder’s acquisition cost less any prior distributions paid to such U.S. holder that were treated as a return of capital for U.S. federal income tax purposes.

Any such capital gain or loss generally will be long-term capital gain or loss if the U.S. holder’s holding period for the Novus Common Stock so disposed of exceeds one year. Under current law, long-term capital gains of non-corporate taxpayers are taxed at a reduced U.S. federal income tax rate (up to a maximum rate of 20%). It is unclear, however, whether the redemption rights with respect to the Novus Common Stock may suspend the running of the applicable holding period for this purpose. Long-term capital gains recognized by non-corporate U.S. holders will be eligible to be taxed at reduced rates. The deductibility of capital losses is subject to limitations.

145

TABLE OF CONTENTS

Taxation of Redemption Treated as a Distribution. If the redemption does not qualify as a sale of Novus Common Stock, a U.S. holder will generally be treated as receiving a distribution. Such distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles.

Distributions in excess of our current and accumulated earnings and profits will constitute a return of capital that will be applied against and reduce (but not below zero) the U.S. holder’s adjusted tax basis in Novus Common Stock. Any remaining excess will be treated as gain realized on the sale or other disposition of the Novus Common Stock as described under “— U.S. Holders — Gain or Loss on Redemption Treated as a Sale of Novus Common Stock” above.

Dividends (including constructive dividends paid pursuant to a redemption of Novus Common Stock) Novus pays to a U.S. holder that is a taxable corporation generally will qualify for the dividends received deduction if the requisite holding period is satisfied. With certain exceptions (including, but not limited to, dividends (including constructive dividends paid pursuant to a redemption of Novus Common Stock) treated as investment income for purposes of investment interest deduction limitations), and provided that certain holding period requirements are met, dividends Novus pays to a non-corporate U.S. holder generally will constitute “qualified dividends” that will be subject to tax at the maximum tax rate accorded to long-term capital gains. It is unclear whether the redemption rights with respect to the Novus Common Stock described in this proxy statement/prospectus may prevent a U.S. holder from satisfying the applicable holding period requirements with respect to the dividends received deduction or the preferential tax rate on qualified dividend income, as the case may be.

Information Reporting and Backup Withholding. In general, information reporting requirements will generally apply to dividends (including constructive dividends paid pursuant to a redemption of Novus Common Stock) paid to a U.S. holder and to the proceeds of the sale or other disposition of shares of Novus Common Stock, unless the U.S. holder is an exempt recipient. Backup withholding may apply to such payments if the U.S. holder fails to provide a taxpayer identification number, a certification of exempt status or has been notified by the IRS that it is subject to backup withholding (and such notification has not been withdrawn).

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a U.S. holder’s federal income tax liability provided that the required information is timely furnished to the IRS.

Medicare Tax on Net Investment Income

Non-corporate U.S. holders whose income exceeds certain thresholds generally will be subject to 3.8% surtax on their “net investment income” (which generally includes, among other things, dividends on, and capital gain from the sale or other taxable disposition of, the Novus Common Stock). Non-corporate U.S. holders should consult their own tax advisors regarding the possible effect of such tax on their ownership and disposition of the Novus Common Stock.

Non-U.S. Holders

Redemption of Novus Common Stock. The characterization for U.S. federal income tax purposes of the redemption of a Non-U.S. holder’s Novus Common Stock pursuant to the redemption provisions described in the section titled “The Special Meeting of Novus’s Stockholders — Redemption Rights” generally will be as described below under “— Non-U.S. Holders — Gain on Redemption Treated as a Sale of Novus Common Stock” and “— Non-U.S. Holders — Taxation of Redemption Treated as a Distribution,” as applicable.

Gain on Redemption Treated as a Sale of Novus Common Stock. A Non-U.S. holder will not be subject to U.S. federal income tax on any gain realized on a redemption treated as a sale of Novus Common Stock, unless:

•

the gain is effectively connected with the Non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. holder maintains a permanent establishment in the United States to which such gain is attributable);

146

TABLE OF CONTENTS

•

the Non-U.S. holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the redemption and certain other requirements are met; or

•

we are or have been a “United States real property holding corporation” for U.S. federal income tax purposes at any time during the shorter of the five-year period ending on the date of disposition or the period that the Non-U.S. holder held Novus Common Stock.

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular graduated rates applicable to U.S. holders. A Non-U.S. holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

Gain described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the Non-U.S. holder (even though the individual is not considered a resident of the United States), provided that the Non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.

If the third bullet point above applies to a Non-U.S. holder, gain recognized by such holder on the sale, exchange or other disposition of shares of Novus Common Stock will be subject to tax at generally applicable U.S. federal income tax rates. In addition, a buyer of Novus Common Stock (Novus would be treated as a buyer with respect to a redemption of Novus Common Stock) may be required to withhold U.S. federal income tax at a rate of 15% of the amount realized upon such disposition. Novus believes that it is not, and has not been at any time since our formation, a United States real property holding corporation and Novus does not expect to be a United States real property holding corporation immediately after the Business Combination is completed.

Taxation of Redemption Treated as a Distribution. If the redemption does not qualify as a sale of Novus Common Stock, a Non-U.S. holder will generally be treated as receiving a distribution. Such distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from Novus’s current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of Novus’s current and accumulated earnings and profits, will constitute a return of capital that will be applied against and reduce (but not below zero) the Non-U.S. holder’s adjusted tax basis in Novus Common Stock. Any remaining excess will be treated as gain realized on the sale or other disposition of the Novus Common Stock and will be treated as described under “— Non-U.S. Holders — Gain on Redemption Treated as a Sale of Novus Common Stock” above. In general, with respect to any distributions that constitute dividends for U.S. federal income tax purposes and are not effectively connected with the Non-U.S. holder’s conduct of a trade or business within the United States, we will be required to withhold tax from the gross amount of the dividend at a rate of 30%, unless such Non-U.S. holder is eligible for a reduced rate of withholding tax under an applicable income tax treaty and provides proper certification of its eligibility for such reduced rate (on an IRS Form W-8BEN or W-8BEN-E or other applicable documentation).

If dividends paid to a Non-U.S. holder are effectively connected with the Non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. holder maintains a permanent establishment in the United States to which such dividends are attributable), the Non-U.S. holder will be exempt from the 30% U.S. federal withholding tax described above if such Non-U.S. holder furnishes to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. holder’s conduct of a trade or business within the United States.

Any such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular graduated rates. A Non-U.S. holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected dividends, as adjusted for certain items. Non-U.S. holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

Information Reporting and Backup Withholding. Payments of dividends (including constructive dividends received pursuant to a redemption of Novus Common Stock) on Novus Common Stock will not

147

TABLE OF CONTENTS

be subject to backup withholding, provided that the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person, and the holder either certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any payments of dividends on Novus Common Stock paid to the Non-U.S. holder, regardless of whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of Novus Common Stock within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a United States person, or the holder otherwise establishes an exemption. Proceeds of a disposition of Novus Common Stock conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. holder resides or is established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. holder’s U.S. federal income tax liability, provided that the required information is timely furnished to the IRS.

FATCA Withholding Taxes.

Sections 1471 to 1474 of the Code (such sections commonly referred to as “FATCA”) impose withholding of 30% on payments of dividends (including constructive dividends received pursuant to a redemption of stock) on Novus Common Stock to stockholders that fail to meet prescribed information reporting or certification requirements. In general, no such withholding will be required with respect to a U.S. holder or an individual Non-U.S. holder that timely provides the certifications required on a valid IRS Form W-9 or W-8BEN, respectively. Holders potentially subject to withholding include “foreign financial institutions” (which is broadly defined for this purpose and in general includes investment vehicles) and “non-financial foreign entities” unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interest in or accounts with those entities) have been satisfied, or an exemption applies (typically certified as to by the delivery of a properly completed IRS Form W-8BEN-E). If FATCA withholding is imposed, a beneficial owner that is not a foreign financial institution or a non-financial foreign entity generally will be entitled to a refund of any amounts withheld by filing a U.S. federal income tax return (which may entail significant administrative burden). Foreign financial institutions and non-financial foreign entities located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules. While withholding under FATCA would have also applied to payments of gross proceeds from the sale or other disposition of Novus Common Stock on or after January 1, 2019, proposed Treasury regulations eliminate such withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. Non-U.S. holders should consult their tax advisers regarding the effects of FATCA on a redemption of Novus Common Stock.

HOLDERS CONTEMPLATING EXERCISE OF THEIR REDEMPTION RIGHTS SHOULD CONSULT, AND RELY SOLELY UPON, THEIR TAX ADVISORS TO DETERMINE THE SPECIFIC TAX CONSEQUENCES TO THEM OF SUCH A REDEMPTION, INCLUDING THE EFFECT OF ANY U.S. FEDERAL, STATE, LOCAL, NON-U.S. OR OTHER TAX LAWS.

U.S. Federal Income Tax Considerations of The Business Combination for Energy Vault’s Stockholders

Subject to the qualifications, assumptions and limitations set forth herein and the U.S. federal income tax opinion filed as Exhibit 8.1 herewith, the following discussion represents the opinion of Blank Rome LLP, counsel to Novus, with respect to the material U.S. federal income tax consequences of the Business Combination to holders of Novus securities.

The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the Code, Treasury regulations promulgated

148

TABLE OF CONTENTS

thereunder, judicial decisions and published rulings and administrative pronouncements of the IRS, in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect holders to which this section applies and could affect the accuracy of the statements herein. Neither Novus nor Energy Vault has sought and neither of them will seek any rulings from the IRS regarding the matters discussed below. There can be no assurance that the IRS or a court will not take a contrary position to that regarding the tax characterization of the Business Combination discussed below.

Characterization of the Business Combination

Each of Novus, Merger Sub, and Energy Vault intend, that, for U.S. federal income tax purposes, the Business Combination qualify as a “reorganization” within the meaning of Section 368(a) of the Code. However, many requirements must be satisfied in order for the Business Combination to qualify as a reorganization under Section 368(a) of the Code, some of which are based upon factual determinations. There is a lack of guidance from the IRS as to the applicability of the “reorganization” provisions of the Code to transactions where a blank check company is a party. Accordingly, it is possible that the IRS or other tax authority will assert that the Business Combination is not treated as a reorganization under Section 368(a) of the Code. In addition, the closing of the Business Combination is not conditioned on its so qualifying, nor is it conditioned on our receipt of a tax opinion that it so qualifies.

In the Business Combination Agreement, each of Novus, Merger Sub, and Energy Vault agrees to use its respective reasonable best efforts to cause the Business Combination to qualify, and agrees not to take, and not to permit or cause any of its affiliates or subsidiaries to take, any action which to its knowledge could reasonably be expected to prevent or impede the Business Combination from qualifying as a reorganization within the meaning of Section 368(a) of the Code. In the Business Combination Agreement, each of Novus, Merger Sub, and Energy Vault agrees, except to the extent otherwise required by a “determination” as such term is used in Section 1313 of the Code, to not take any position or action inconsistent with the intended tax treatment (whether in audits, tax returns or otherwise). Consistent with the Business Combination Agreement, Energy Vault intends to file its tax returns consistent with the Business Combination being treated as a reorganization pursuant to Section 368(a) of the Code. However, no representation is being made herein or in the Business Combination Agreement that the Business Combination is tax-free (whether pursuant to Section 368(a) of the Code or otherwise) to any party.

Consequences of the Business Combination to Holders of Novus Common Stock

With respect to holders of Novus Common Stock prior to the Business Combination, such holders of Novus Common Stock who do not exercise their redemption rights will retain their Novus Common Stock, will not receive any consideration in the Business Combination and will not receive any additional shares of Novus Common Stock in the Business Combination. As a result, there will be no material U.S. federal income tax consequences to the current holders of Novus Common Stock as a result of the Business Combination, regardless of whether or not the Business Combination qualifies as a “reorganization” within the meaning of Section 368(a) of the Code.

Consequences of the Business Combination to Holders of Energy Vault Common Stock

With respect to holders of Energy Vault Common Stock who exchange their Energy Vault Common Stock for Novus Common Stock pursuant to the Business Combination, the U.S. federal income tax consequences of the Business Combination generally will depend upon whether the Business Combination qualifies as a “reorganization” within the meaning of Section 368 of the Code. No assurance can be given that the IRS will not assert, or that a court would not sustain, a position contrary to any of those set forth below. Accordingly, each holder of shares of Energy Vault Common Stock is urged to consult its tax advisor with respect to the particular tax consequences of the Business Combination to such holder.

Consequences to Holders of Energy Vault Common Stock if the Business Combination Qualifies as a Reorganization

If the Business Combination qualifies as a reorganization, holders of Energy Vault Common Stock generally should not recognize gain or loss for U.S. federal income tax purposes on the exchange of Energy

149

TABLE OF CONTENTS

Vault Common Stock for Novus Common Stock Common Stock pursuant to the Business Combination (except with respect to any Earn Out Shares treated as imputed interest, which will be taxable upon receipt as ordinary income as described below). In that case, the aggregate adjusted tax basis of a holder in the Novus Common Stock received in the Business Combination (including any Earn Out Shares received, other than any Earn Out Shares that represent imputed interest as described below) generally should equal the aggregate adjusted tax basis of Energy Vault Common Stock surrendered in exchange therefor, and the holder’s holding period for the Novus Common Stock received in the exchange by such holder (including any Earn Out Shares received, other than any Earn Out Shares that represent imputed interest as described below) should include the holding period for the Energy Vault Common Stock surrendered in the exchange that were held by such holder. A portion of any Earn Out Shares a holder receives pursuant to the Business Combination six months or more after the Closing will be taxable upon receipt as imputed interest and as ordinary income, even though there will not be any corresponding receipt of cash. A holder’s basis in any such Earn Out Shares treated as imputed interest will equal the fair market value of such shares on the date of receipt, and the holder’s holding period in such Earn Out Shares will begin on the day following the date of receipt.

Holders who hold different blocks of shares of Energy Vault Common Stock (generally, purchased or acquired on different dates or at different prices) should consult their tax advisors to determine how the above rules apply to them, and the discussion above does not specifically address all of the consequences to holders who hold different blocks of stock.

Each U.S. holder of Energy Vault Common Stock who receives shares of Novus Common Stock in the Business Combination is generally required to retain permanent records pertaining to the Business Combination, and make such records available to any authorized IRS officers and employees. Such records should specifically include information regarding the amount, basis, and fair market value of all transferred property, and relevant facts regarding any liabilities assumed or extinguished as part of such reorganization. Additionally, certain information reporting requirements may apply to U.S. holders of Energy Vault Common Stock who owned immediately before completion of the Business Combination at least 1% (by vote or value) of the total outstanding stock of Energy Vault, or Energy Vault “securities” (as specially defined for U.S. federal income tax purposes) the aggregate federal income tax basis of which was at least $1 million.

Consequences to Holders of Energy Vault Common Stock if the Business Combination does not Qualify as a Reorganization

U.S. Holders

If the Business Combination fails to qualify as a reorganization within the meaning of Section 368(a) of the Code, then a U.S. holder of Energy Vault Common Stock would recognize gain or loss upon the exchange of the holder’s shares of Energy Vault Common Stock for shares of Novus Common Stock equal to the difference between the fair market value, at the time of the exchange, of the Novus Common Stock received in the Business Combination (including any cash or property other than Novus Common Stock received in the Business Combination) and such U.S. holder’s tax basis in the shares of Energy Vault Common Stock surrendered in the Business Combination. For these purposes, the share of the total consideration received by a holder of Energy Vault Common Stock will include his, her or its pro rata portion of the Earn Out Shares, generally based on the fair market value of the right to receive the Earn Out Shares as of the Closing unless such fair market value is not reasonably ascertainable, in which case payments of the Earn Out Shares would be taken into account when made or deemed made in accordance with the holder’s regular method of accounting for U.S. federal income tax purposes. The Earn Out Shares should generally be eligible for installment sale reporting and a portion of any such deferred payments would be subject to the imputed interest rules similar to those described above and may be subject to an additional interest charge. The amount and timing of any gain recognition would depend, in part, upon whether the installment method of reporting is applied to the receipt of Earn Out Shares. Holders of Energy Vault Common Stock should consult their tax advisors regarding the advisability of electing out of the installment method in light of their particular circumstances. Such gain or loss would be long-term capital gain or loss if the Energy Vault Common Stock was held for more than one year at the time of the Business Combination. Under current law, long-term capital gains of non-corporate taxpayers are taxed at a reduced U.S. federal income tax rate (up

150

TABLE OF CONTENTS

to a maximum rate of 20%). In addition, the aggregate tax basis of the shares of Novus Common Stock received in the Business Combination by a U.S. holder of Energy Vault Common Stock would equal their fair market value at the time of the closing of the Business Combination, and the U.S. holder’s holding period of such shares of Novus Common Stock would commence the day after the closing of the Business Combination. Under current law, the deductibility of capital losses is subject to limitations.

Non-U.S. Holders

If the Business Combination does not qualify as a reorganization under Section 368(a) of the Code, Non-U.S. holders of Energy Vault will not be subject to U.S. federal income tax in connection with the Business Combination except to the extent described below.

If gain recognized upon the exchange of the holder’s shares of Energy Vault Common Stock for shares of Novus Common Stock is effectively connected with the Non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. holder maintains a permanent establishment in the United States to which such gain is attributable), such gain will be subject to U.S. federal income tax on a net income basis at the regular graduated rates applicable to U.S. holders. A Non-U.S. holder of Energy Vault Common Stock that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items. In addition, if a Non-U.S. holder of Energy Vault Common Stock is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the Business Combination and certain other requirements are met, gain recognized by such holder with respect to such holder’s Energy Vault Common Stock as a result of the Business Combination will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the Non-U.S. holder of Energy Vault Common Stock (even though the individual is not considered a resident of the United States), provided that the Non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses. Finally, if Energy Vault is or has been a “United States real property holding corporation” for U.S. federal income tax purposes at any time during the shorter of the five-year period ending on the date of the Business Combination or the period that the Non-U.S. holder held Energy Vault Common Stock, any gain recognized by such holder with respect to such holder’s Energy Vault Common Stock as a result of the Business Combination would generally be subject to tax at applicable U.S. federal income tax rates and a U.S. federal withholding tax could apply. However, Energy Vault believes that it is not, and has not been at any time since its formation, a United States real property holding corporation and neither Energy Vault nor Novus expects to be a United States real property holding corporation immediately after the Business Combination is completed.

Notwithstanding the foregoing, a Non-U.S. holder may be subject to U.S. federal income tax (and withholding with respect thereto) for any Earn Out Shares treated as imputed interest.

HOLDERS OF ENERGY VAULT COMMON STOCK SHOULD CONSULT, AND RELY SOLELY UPON, THEIR TAX ADVISORS TO DETERMINE THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE BUSINESS COMBINATION, INCLUDING THE EFFECT OF ANY U.S. FEDERAL, STATE, LOCAL, NON-U.S. OR OTHER TAX LAWS.

2d. The Director Removal Charter Amendment — to provide that any director or the entire board of directors of Novus may be removed from office at any time, but only for cause and only by the affirmative vote of the holders of at least 662∕3% of the voting power of all then-oustanding shares of Novus's capital stock entitled to vote thereon, voting together as a single class;

The Proposed Certificate of Incorporation will provide that any director or the entire board of directors of Novus may be removed from office at any time, but only for cause and only by the affirmative vote of the holders of at least 66 2/3% of the voting power of all then-oustanding shares of Novus's capital stock entitled to vote thereon, voting together as a single class.

Provisions Specific to a Blank Check Company	Under the Existing Certificate of Incorporation, Article Sixth sets forth various provisions related to its operations as a blank check company prior to the consummation of an initial business combination.	The Proposed Certificate of Incorporation will not include these blank check company provisions because, upon consummation of the Business Combination, Novus will cease to be a blank check company. In addition, the provisions requiring that the proceeds from its initial public offering be held in a trust account until a business combination or liquidation of Novus and the terms governing Novus’s consummation of a proposed business combination will not be applicable following consummation of the Business Combination.

Reasons for the Amendments to the Existing Certificate of Incorporation

Name Change

Changing the post-combination corporate name from “Novus Capital Corporation II” to “Energy Vault Holdings, Inc.” is desirable to reflect the business combination with Energy Vault and to clearly identify the Combined Company as the publicly traded entity. Additionally, Novus’s board of directors believes the name of the Combined Company should more closely align with the name of the existing operating business of Energy Vault.

Elimination of Class B Common Stock

The Existing Certificate of Incorporation contains provisions regarding the conversion of Novus Class B Common Stock and anti-dilution protections in respect of Novus Class B Common Stock. The Existing Charter also requires the affirmative vote of the holders of a majority of the shares of Novus Class B Common Stock in order to make any amendment that would alter or change the powers, preferences or other rights of the holders of Novus Class B Common Stock. The Proposed Certificate of Incorporation eliminates Novus Class B Common Stock and any rights of holders thereof. Following the merger, all shares of Novus Class B Common Stock will have converted into Novus Common Stock and the protections afforded the Novus Class B Common Stock while Novus was a special purpose acquisition company will no longer be necessary. Novus’s board of directors believes that the provisions relating to the Novus Class B Common Stock will no longer be relevant to the Combined Company and should be eliminated.

Under the Existing Certificate of Incorporation, only holders of Novus Class B Common Stock are entitled to take action by written consent pursuant to Section 228 of the DGCL. The Proposed Certificate of Incorporation eliminates the Novus Class B Common Stock and provides that no holders of Novus Common Stock shall be entitled to take action by written consent pursuant to Section 228 of the DGCL. The elimination of stockholder written consents prevent a controlling stockholder or group of stockholders from amending the Proposed Certificate or bylaws of the Combined Company or removing directors without calling a special meeting of the stockholders and waiting the notice periods determined by the Combined Company Board pursuant to the bylaws prior to taking any such action. This guarantees that stockholders are given sufficient time to weigh the arguments presented by both sides in connection with any

154

TABLE OF CONTENTS

contested stockholder vote. Notwithstanding the foregoing, elimination of such stockholder written consents may lengthen the amount of time required to take stockholder actions since actions by written consent are generally not subject to the minimum notice requirement of a stockholders’ meeting.

Director Removal Amendment

The Director Removal Amendment is desirable to enhance the continuity and stability of the Combined Company Board. The supermajority voting requirements contained therein, and the requirement that directors be removed for cause, are appropriate at this time to protect all stockholders against the potential self-interested actions by one or a few large stockholders. We further believe that going forward, a supermajority voting requirement encourages the person seeking control of the Combined Company to negotiate with the Combined Company Board to reach terms that are appropriate for all stockholders.

Corporate Opportunity Amendment

The “corporate opportunity” doctrine provides that directors and officers of a corporation, as part of their duty of loyalty to the corporation and its stockholders, generally have a fiduciary duty to disclose opportunities to the corporation that are related to its business and are prohibited from pursuing those opportunities unless the corporation determines that it is not going to pursue them. Section 122 (17) of the DGCL expressly permits Delaware corporations, such as Novus, to renounce any interest or expectancy of the corporation in certain business opportunities. The Existing Certificate currently provides that certain business opportunities are not subject to the “corporate opportunity” doctrine. The Proposed Certificate will be silent on the issue of the application of the doctrine of corporate opportunity.

Charter Amendment

Requiring the approval by affirmative vote of holders of at least 66 2/3% of the voting power of the Combined Company’s then-outstanding shares of capital stock entitled to vote generally at an election of directors to make any amendment to certain provisions of the Proposed Certificate is intended to protect key provisions of the Proposed Certificate from arbitrary amendment and to prevent a simple majority of stockholders from taking actions that may be harmful to other stockholders or making changes to provisions that are intended to protect all stockholders.

Bylaws Amendment

Requiring the approval by affirmative vote of holders of at least 66 2/3% of the voting power of the Combined Company’s then-outstanding shares of capital stock entitled to vote generally at an election of directors to make any amendment to the Combined Company’s bylaws is intended to protect key provisions of the Combined Company’s bylaws from arbitrary amendment and to prevent a simple majority of stockholders from taking actions that may be harmful to other stockholders or making changes to provisions that are intended to protect all stockholders.

Provisions Specific to a Blank Check Company

The elimination of certain provisions related to Novus’s status as a blank check company is desirable because these provisions will serve no purpose following the Business Combination. For example, the Proposed Certificate does not include the requirement to dissolve the Combined Company after a certain time period and allows it to continue as a corporate entity with perpetual existence following consummation of the Business Combination. Perpetual existence is the usual period of existence for corporations, and the Novus’s board of directors believes it is the most appropriate period for the Combined Company following the Business Combination. In addition, certain other provisions in the Existing Certificate require that proceeds from Novus’s IPO be held in the trust account until a business combination or liquidation of Novus has occurred. These provisions cease to apply once the Business Combination is consummated and are therefore not included in the Proposed Certificate.

Vote Required for Approval

Each of Charter Proposals 2a through 2g will be approved and adopted if the holders of a majority of all outstanding shares of Novus Common Stock and Novus Class B Common Stock entitled to vote thereon,

155

TABLE OF CONTENTS

voting as a single class, and a majority of all of the outstanding shares of Novus Class B Common Stock voting separately as a single class at the special meeting vote “FOR” such respective Charter Proposals. Each of Charter Proposals 2a through 2g needs to be approved in order for the Charter Proposals to be approved.

Adoption of the Charter Proposals is conditioned on the approval of the Business Combination Proposal, the Equity Incentive Plan Proposal and the NYSE Proposal at the special meeting.

The Closing is conditioned on the approval of the Business Combination Proposal, each of the Charter Proposals, the Equity Incentive Plan Proposal and the NYSE Proposal at the special meeting.

Recommendation of Novus’s Board of Directors

NOVUS’S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THE APPROVAL OF EACH OF THE CHARTER PROPOSALS 2A THROUGH 2G.

TABLE OF CONTENTS

PROPOSAL NO. 3 — THE EQUITY INCENTIVE PLAN PROPOSAL

Overview

Prior to the consummation of the Business Combination, Novus’s board of directors is expected to approve and adopt, subject to Novus stockholder approval, the 2022 Plan. If the 2022 Plan is approved by stockholders, the Combined Company will be authorized to grant equity awards to eligible service providers upon consummation of the Business Combination (the “Business Combination Date”). A copy of the 2022 Plan is attached to this proxy statement/prospectus as Annex C. Novus’s board of directors is still in the process of developing, approving and implementing the 2022 Plan and, accordingly, there can be no assurance that the 2022 Plan will be implemented or will contain the terms described below. Our stockholders are being asked to approve the 2022 Plan as presented.

Purpose of the 2022 Plan

The purpose of the 2022 Plan is to attract, retain, incentivize and reward service providers who will contribute to the Combined Company’s success. Novus believes that equity compensation is critical in attracting and retaining top talent and will help focus them on the creation of long-term value consistent with the interests of Novus’s stockholders.

Reasons for the Approval of the Equity Incentive Plan Proposal

Stockholder approval of the 2022 Plan is necessary in order for Novus to (a) meet the stockholder approval requirements of The New York Stock Exchange and (b) grant incentive stock options (“ISOs”). Stockholders are also being asked to approve an annual limitation on the compensation paid to non-employee directors.

Consequences if the 2022 Plan Proposal is Not Approved

If the Equity Incentive Plan Proposal is not approved by Novus’s stockholders, the 2022 Plan will not become effective and the Combined Company will not be able to grant equity awards under the 2022 Plan. Novus believes its ability to recruit, retain and incentivize top talent will be adversely affected if the Equity Incentive Plan Proposal is not approved.

Material Terms of the 2022 Plan

The material terms of the 2022 Plan, as currently contemplated by Novus’s board of directors, are summarized below. This summary, however, is not intended to be a complete description of the 2022 Plan and is qualified in its entirety by reference to the complete text of the 2022 Plan, which is attached to this proxy statement/prospectus as Annex C. To the extent there is a conflict between the terms of this summary and the 2022 Plan, the terms of the 2022 Plan will control. As noted above, Novus’s board of directors is in the process of developing, approving and implementing the 2022 Plan and, accordingly, there can be no assurance that the 2022 Plan will be implemented or will contain the terms described below. Accordingly, this summary is subject to change. Novus’s stockholders are being asked to approve the 2022 Plan as presented.

Types of Awards. The 2022 Plan provides for the grant stock options, which may be ISOs or non-statutory stock options (“NSOs”), stock appreciation rights (“SARs”), restricted shares and restricted stock units (“RSUs”), or collectively, awards.

Administration. The 2022 Plan will be administered by the Combined Company Board or by one or more committees to which the board of directors delegates such administration (as applicable, the “Administrator”). Subject to the terms of the 2022 Plan, the Administrator will have the complete discretion to determine the eligible individuals who are to receive awards under the plan, to determine the terms and conditions of awards granted under the 2022 Plan and to make all decisions related to the 2022 Plan and awards granted thereunder.

Share Reserve. The number of shares of Combined Company Common Stock that may be issued under the 2022 Plan is equal to the sum of (x) 15,516,760 shares, plus (y) up to 8,251,906 shares subject to awards granted under the Energy Vault, Inc. 2017 Stock Incentive Plan and the Energy Vault, Inc. 2020 Stock

157

TABLE OF CONTENTS

Plan (the “Predecessor Plans”) that are outstanding on the Business Combination Date and that are subsequently forfeited, expire or lapse unexercised or unsettled or are reacquired by the Combined Company, plus (z) the annual increase in shares described below. While a maximum 8,251,906 shares may be added to the 2022 Plan from the Predecessor Plans, since this assumes that all awards outstanding under the Predecessor Plans on the Business Combination Date will be forfeited, Novus expects the actual number of shares added to the 2022 Plan to be less.

On the first day of each fiscal year during the term of the 2022 Plan, beginning on March 1, 2022 and ending on (and including) March 1, 2031, the number of shares of Combined Company Common Stock that may be issued under the 2022 Plan will increase by a number of shares equal to the lesser of (a) 4% of the outstanding shares on the last day of the immediately preceding fiscal year or (b) such lesser number of shares (including zero) that the Administrator determines for purposes of the annual increase for that fiscal year.

If options, stock appreciation rights, restricted stock units or any other awards are forfeited, cancelled or expire, the shares subject to such awards will again be available for issuance under the 2022 Plan. If stock appreciation rights are exercised or restricted stock units are settled, only the number of shares actually issued upon exercise or settlement of such awards will reduce the number of shares available under the 2022 Plan. If restricted shares or shares issued upon exercise of an option are reacquired by the Combined Company pursuant to a forfeiture provision, repurchase right or for any other reason, then such shares will again be available for issuance under the 2022 Plan. Shares applied to pay the exercise price of an option or satisfy withholding taxes related to any award will again become available for issuance under the 2022 Plan. To the extent an award is settled in cash, the cash settlement will not reduce the number of shares available for issuance under the 2022 Plan.

Shares issued under the 2022 Plan may be authorized but unissued shares or treasury shares. As of the date hereof, no awards have been granted under the 2022 Plan.

Incentive Stock Option Limit. No more than 9,205,979 shares of Combined Company Common Stock may be issued under the 2022 Plan upon the exercise of ISOs.

Annual Limitation on Compensation of Non-Employee Directors. The grant date fair value of awards granted to each non-employee director during any fiscal year of the Combined Company, together with the value of any cash compensation paid to the non-employee director during such fiscal year, may not exceed $750,000. This limit is increased to $1,000,000 in the fiscal year a non-employee director is initially appointed or elected to the board of directors. Compensation paid to an individual for services as an employee or consultant will not count towards these limitations.

Eligibility. Employees (including officers), non-employee directors and consultants who render services to the Combined Company or a parent, subsidiary or affiliate thereof (whether now existing or subsequently established) are eligible to receive awards under the 2022 Plan. ISOs may only be granted to employees of the Combined Company or a parent or subsidiary thereof (whether now existing or subsequently established). As of the Record Date, and assuming closing of the Business Combination, approximately 14 persons (including eight executive officers and six non-employee directors) would be eligible to participate in the 2022 Plan.

Repricing. The Administrator has full authority to reprice (reduce the exercise price of) options and stock appreciation rights or to approve programs in which options and stock appreciation rights are exchanged for cash or other equity awards on terms the Administrator determines.

Stock Options. A stock option is the right to purchase a certain number of shares of stock at a fixed exercise price which, pursuant to the 2022 Plan, may not be less than 100% of the fair market value of the Combined Company Common Stock on the date of grant. Subject to limited exceptions an option may have a term of up to 10 years and will generally expire sooner if the optionee’s service terminates. Options will vest at the rate determined by the Administrator. An optionee may pay the exercise price of an option in cash, or, with the administrator’s consent, with shares of Combined Company Common Stock the optionee already owns, with proceeds from an immediate sale of the option shares through a broker approved by us, through a net exercise procedure or by any other method permitted by applicable law.

158

TABLE OF CONTENTS

Stock Appreciation Rights. A stock appreciation right provides the recipient with the right to the appreciation in a specified number of shares of stock. The Administrator determines the exercise price of stock appreciation rights granted under the 2022 Plan, which may not be less than 100% of the fair market value of the Combined Company Common Stock on the date of grant. Subject to limited exceptions a stock appreciation right may have a term of up to 10 years and will generally expire sooner if the recipient’s service terminates. SARs will vest at the rate determined by the Administrator. Upon exercise of a SAR, the recipient will receive an amount in cash, stock, or a combination of stock and cash determined by the Administrator, equal to the excess of the fair market value of the shares being exercised over their exercise price.

Tax Limitations on Incentive Stock Options. The aggregate fair market value, determined at the time of grant, of Combined Company Common Stock with respect to ISOs that are exercisable for the first time by an option holder during any calendar year under all of the Combined Company’s stock plans may not exceed $100,000. Options or portions thereof that exceed such limit will generally be treated as NSOs. No ISO may be granted to any person who, at the time of the grant, owns or is deemed to own stock possessing more than 10% of the Combined Company’s total combined voting power or that of any of the Combined Company’s affiliates unless (1) the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant, and (2) the term of the ISO does not exceed five years from the date of grant.

Restricted Stock Awards. Shares of restricted stock may be issued under the 2022 Plan for such consideration as the Administrator may determine, including cash, services rendered or to be rendered to the Combined Company, promissory notes or such other forms of consideration permitted under applicable law. Restricted shares may be subject to vesting, as determined by the Administrator. Recipients of restricted shares generally have all of the rights of a stockholder with respect to those shares, including voting rights, however any dividends and other distributions on restricted shares will generally be subject to the same restrictions and conditions as the underlying shares.

Restricted Stock Units. A restricted stock unit is a right to receive a share, at no cost to the recipient, upon satisfaction of certain conditions, including vesting conditions, established by the Administrator. RSUs vest at the rate determined by the Administrator and any unvested RSUs will generally be forfeited upon termination of the recipient’s service. Settlement of restricted stock units may be made in the form of cash, Combined Company Common Stock or a combination of cash and Combined Company Common Stock, as determined by the Administrator. Recipients of restricted stock units generally will have no voting or dividend rights prior to the time the vesting conditions are satisfied and the award is settled. At the Administrator’s discretion and as set forth in the applicable restricted stock unit agreement, restricted stock units may provide for the right to dividend equivalents which will generally be subject to the same conditions and restrictions as the restricted stock units to which they pertain.

Other Awards. The Administrator may grant other awards based in whole or in part by reference to Combined Company Common Stock and may grant awards under other plans and programs that will be settled with shares issued under the 2022 Plan. The Administrator will determine the terms and conditions of any such awards.

Changes to Capital Structure. In the event of certain changes in capitalization, including a stock split, reverse stock split or stock dividend, proportionate adjustments will be made in the number and kind of shares available for issuance under the 2022 Plan, the number of shares that may be added to the 2022 Plan from the Predecessor Plans, the limit on the number of shares that may be issued under the 2022 Plan as ISOs, the number and kind of shares subject to each outstanding award and/or the exercise price of each outstanding award.

Corporate Transactions. If the Combined Company is party to a merger, consolidation or certain change in control transactions, each outstanding award will be treated as described in the definitive transaction agreement or as the Administrator determines, which may include the continuation, assumption or substitution of an outstanding award, the cancellation of an outstanding award after an opportunity to exercise or the cancellation of an outstanding award in exchange for a payment equal to the value of the shares subject to such award less any applicable exercise price. In general, if an award held by a participant who

159

TABLE OF CONTENTS

remains in service at the effective time of a change in control transaction is not continued, assumed or substituted, then the award will vest in full.

Change of Control. The Administrator may provide, in an individual award agreement or in any other written agreement with a participant, that the award will be subject to acceleration of vesting and exercisability in the event of a change of control or in connection with a termination of employment in connection with or following a change in control.

Transferability of Awards. Unless the Administrator determines otherwise, an award generally will not be transferable other than by beneficiary designation, a will or the laws of descent and distribution. The Administrator may permit transfer of an award in a manner consistent with applicable law.

Amendment and Termination. The Administrator may amend or terminate the 2022 Plan at any time. Any such amendment or termination will not affect outstanding awards. If not sooner terminated, the 2022 Plan will terminate automatically in 2031, 10 years after its adoption by Novus’s board of directors. Shareholder approval is not required for any amendment of the 2022 Plan, unless required by applicable law or exchange listing standards.

Certain Federal Income Tax Aspects of Awards Under the 2022 Plan

This is a brief summary of the U.S. federal income tax aspects of awards that may be made under the 2022 Plan based on existing U.S. federal income tax laws as of the date of this proxy statement/prospectus. This summary covers only the basic tax rules. It does not describe a number of special tax rules, including the alternative minimum tax and various elections that may be applicable under certain circumstances. It also does not reflect provisions of the income tax laws of any municipality, state or foreign country in which a holder may reside, nor does it reflect the tax consequences of a holder’s death. Therefore, no one should rely on this summary for individual tax compliance, planning or decisions. Participants in the 2022 Plan should consult their own professional tax advisors concerning tax aspects of awards under the 2022 Plan. The discussion below concerning tax deductions that may become available to the Combined Company under U.S. federal tax law is not intended to imply that the Combined Company will necessarily obtain a tax benefit or asset from those deductions. The tax consequences of awards under the 2022 Plan depend upon the type of award. Changes to tax laws following the date of this proxy statement/prospectus/consent solicitation statement could alter the tax consequences described below.

Incentive Stock Options. No taxable income is recognized by an optionee upon the grant or vesting of an ISO, and no taxable income is recognized at the time an ISO is exercised unless the optionee is subject to the alternative minimum tax. The excess of the fair market value of the purchased shares on the exercise date over the exercise price paid for the shares is includable in alternative minimum taxable income.

If the optionee holds the purchased shares for more than one year after the date the ISO was exercised and more than two years after the ISO was granted (the “required ISO holding periods”), then the optionee will generally recognize long-term capital gain or loss upon disposition of such shares. The gain or loss will equal the difference between the amount realized upon the disposition of the shares and the exercise price paid for such shares. If the optionee disposes of the purchased shares before satisfying either of the required ISO holding periods, then the optionee will recognize ordinary income equal to the fair market value of the shares on the date the ISO was exercised over the exercise price paid for the shares (or, if less, the amount realized on a sale of such shares). Any additional gain will be a capital gain and will be treated as short-term or long-term capital gain depending on how long the shares were held by the optionee.

Nonstatutory Stock Options. No taxable income is recognized by an optionee upon the grant or vesting of an NSO. The optionee will generally recognize ordinary income in the year in which the option is exercised equal to the excess of the fair market value of the purchased shares on the exercise date over the exercise price paid for the shares. If the optionee is an employee or former employee, the optionee will be required to satisfy the tax withholding requirements applicable to such income. Upon resale of the purchased shares, any subsequent appreciation or depreciation in the value of the shares will be treated as short-term or long-term capital gain or loss depending on how long the shares were held by the optionee.

Restricted Stock. A participant who receives an award of restricted stock generally does not recognize taxable income at the time of the award. Instead, the participant recognizes ordinary income when the shares

160

TABLE OF CONTENTS

vest, subject to withholding if the participant is an employee or former employee. The amount of taxable income is equal to the fair market value of the shares on the vesting date(s) less the cash, if any, paid for the shares. Alternatively a participant may make a one-time election to recognize income at the time the participant receives restricted stock in an amount equal to the fair market value of the restricted stock (less any cash paid for the shares) on the date of the award by making an election under Section 83(b) of the Code.

Restricted Stock Unit Awards. In general, no taxable income results upon the grant of an RSU. The recipient will generally recognize ordinary income, subject to withholding if the recipient is an employee or former employee, equal to the fair market value of the shares that are delivered to the recipient upon settlement of the RSU. Upon resale of the shares acquired pursuant to an RSU, any subsequent appreciation or depreciation in the value of the shares will be treated as short-term or long-term capital gain or loss depending on how long the shares were held by the recipient.

Stock Appreciation Rights. In general, no taxable income results upon the grant of a SAR. A participant will generally recognize ordinary income in the year of exercise equal to the value of the shares or other consideration received. In the case of a current or former employee, this amount is subject to withholding.

Section 409A. The foregoing description assumes that Section 409A of the Code does not apply to an award. In general, options and stock appreciation rights are exempt from Section 409A if the exercise price per share is at least equal to the fair market value per share of the underlying stock at the time the option or stock appreciation right was granted. RSUs are subject to Section 409A unless they are settled within two and one half months after the end of the later of (i) the end of the Combined Company’s fiscal year in which vesting occurs or (ii) the end of the calendar year in which vesting occurs. Restricted stock awards are not generally subject to Section 409A. If an award is subject to Section 409A and the provisions for the exercise or settlement of that award do not comply with Section 409A, then the participant would be required to recognize ordinary income whenever a portion of the award vested (regardless of whether it had been exercised or settled). This amount would also be subject to a 20% U.S. federal tax in addition to the U.S. federal income tax at the participant’s usual marginal rate for ordinary income.

Tax Treatment of the Combined Company. The Combined Company will generally be entitled to an income tax deduction at the time and to the extent a participant recognizes ordinary income as a result of an award granted under the 2022 Plan. However, Section 162(m) of the Code may limit the deductibility of certain awards granted under the 2022 Plan. Although the Administrator considers the deductibility of compensation as one factor in determining executive compensation, the Administrator retains the discretion to award and pay compensation that is not deductible as it believes that it is in the stockholders’ best interests to maintain flexibility in the approach to executive compensation and to structure a program that the Combined Company considers to be the most effective in attracting, motivating and retaining key employees.

2022 Plan Benefits

No awards will be made under the 2022 Plan until after the Business Combination Date. Because the 2022 Plan is discretionary, benefits to be received by individual participants are not determinable.

Securities Authorized for Issuance under Equity Compensation Plans

As of September 30, 2021, an aggregate of 30,000 shares were to be issued upon the exercise of outstanding options under the 2017 Stock Incentive Plan, and an aggregate of 147,000 shares were to be issued upon the exercise of outstanding options under the 2020 Stock Plan, which will each be assumed by the Combined Company. Following the Closing, no further grants or awards will be made under either the 2017 Stock Incentive Plan or the 2020 Plan. The weighted-average exercise price of outstanding options under the 2017 Stock Incentive Plan and the 2020 Stock Plan was $4.78. As of the Record Date, the last reported price on NYSE of a share of Novus Common Stock was $ .

Registration with the SEC

If the 2022 Plan is approved by Novus’s stockholders, the Combined Company intends to file a registration statement on Form S-8 registering the shares reserved for issuance under the 2022 Plan as soon as reasonably practicable after the Combined Company becomes eligible to use such form.

INFORMATION ABOUT ENERGY VAULT

Unless the context otherwise requires, all references in this section to “we,” the “Company,” “us,” or “our” refer to Energy Vault and its subsidiary prior to the consummation of the Business Combination.

Company Overview

Energy Vault develops sustainable, grid-scale energy storage solutions designed to advance the transition to a carbon free, resilient power grid. Energy Vault’s mission is to accelerate the decarbonization of our economy through the development of sustainable and economical energy storage technologies. To achieve this, Energy Vault is developing a proprietary gravity-based energy storage technology. Energy Vault is also designing proprietary energy management software based on artificial intelligence (AI), advanced optimization algorithms designed to control and optimize entire energy systems and a flexible energy storage integration platform suitable for storage technologies of many durations. Energy Vault’s product platform aims to help utilities, independent power producers, and large energy users significantly reduce their levelized cost of energy while maintaining power reliability.

Energy Vault was founded to address one of the greatest impediments to efficient renewable energy adoption — electricity storage. Renewable energy solutions struggle to replace fossil fuel power due to intermittency of the generation source and the lack of economic and sustainable energy storage solutions. Variable renewable energy sources such as wind and solar only produce energy when the sun is shining, or when the wind is blowing. Cost-effective energy storage is required to increase the amount of electricity that can be delivered to the grid from renewable energy sources in a balanced way that supports grid integration resiliency during low generation and eliminates overgeneration and the risk of changes in energy delivery, or ramp rate. Ramp rate is measured as the percentage of change in energy delivered per second. Power plants are designed to operate within a range where the amount of energy delivered to the grid must always equal the amount of energy that is being consumed. Blackouts and other issues can result when the balance is disrupted, when the energy levels fall out of the set range due to low generation periods or high energy demand periods. The system also may become overloaded because of abrupt changes in renewable energy generation. Energy storage helps to maintain the balance of energy delivery with energy consumed and to mitigate ramp rate to stay within range and avoid blackouts or other grid resiliency problems.

Energy Vault’s gravity-based solutions are based on the well-understood physics and mechanical engineering fundamentals of pumped hydroelectric energy storage, but replace water with custom-made composite blocks, or “mobile masses”, that can be made from low-cost and locally sourced materials, including local soil, mine tailings, coal combustion residuals (coal ash), and end-of-life decommissioned wind turbine blades.

Energy Vault’s gravity-based solutions build upon the core, proven energy storage technology of pumped hydroelectric energy storage and incorporates a simplified building design that is modular, flexible and not limited by the same geological constraints of pumped hydroelectric energy storage plants. Applying the fundamental principles of gravity and potential energy, Energy Vault’s EVx and Energy Vault Resiliency Center (EVRC) solutions combine advanced materials science and proprietary machine-vision software to autonomously orchestrate the charge, storage, and discharge of electricity in grid-scale applications. To achieve this, Energy Vault synthesized technologies from four established industries: crane/elevators, shipping, motor/generator, and materials science. Combining potential and kinetic energy cycles, Energy Vault's systems are automated with advanced computer control and machine vision software to create a gravity energy storage innovation designed to meet the market demand for 2-12 hours of storage duration. Energy Vault’s EVx and EVRC systems are designed to serve economically both higher power/shorter duration applications with ancillary services1 from 2-4 hours, while scaling to serve medium (4-10 hours) and long duration (ten or more hour) requirements.

Ancillary services as defined by the United States Federal Energy Regulatory Commission are those services necessary to support the transmission of electric power from seller to purchaser, given the obligations of control areas and transmitting utilities within those control areas, to maintain reliable operations of the interconnected transmission system.

166

TABLE OF CONTENTS

Energy Vault’s storage, when combined with low-cost wind and photovoltaic solar, is designed to achieve an attractive levelized cost of energy delivered. Energy Vault’s EVx and EVRC systems can be deployed as stand-alone storage connected to the grid or alongside any generation source, such as wind or solar farms. Energy Vault is focused on enabling cost-effective renewable power on a global scale at a lower cost than existing, fully-depreciated fossil fuel plants and with high sustainability standards. The potential energy of the system can be stored with the composite blocks in the raised position for unlimited periods of time and with nearly zero expected loss of the storage capacity over time. Additionally, Energy Vault is uniquely positioned to work with traditional fossil fuel companies to help utilities and coal plant operators make a more cost-effective transition to green power by utilizing energy waste materials such as coal ash in the production of the mobile masses that charge Energy Vault’s gravity energy storage solutions.

The circular economy is a model of production and consumption, which involves sharing, leasing, reusing, repairing, refurbishing, and recycling existing materials and products as long as possible. In this way, the life cycle of products is extended to help minimize waste. Energy Vault has a unique approach to the circular economy which involves beneficial reuse of recyclable and energy waste materials into its sustainable production design.

In July 2020, Energy Vault completed mechanical construction of a five MW commercial demonstration unit (CDU) located in Arbedo-Castione, Switzerland based on the EV1 Tower design. In July 2020, the CDU was connected to the Swiss national electricity grid. Following the successful commercial scale deployment of the CDU, Energy Vault announced the new EVx platform in June 2021 concurrent with its announcement of an investment in Energy Vault from Saudi Aramco Energy Ventures. EVx will offer performance enhancements designed to have 80%-85% round trip efficiency, a 35-year life, and a flexible, modular design that is 45% lower in height than the EV1 Tower design. Round trip efficiency is the ratio between the amount of energy that is delivered from the charged system and the amount of energy that was used to charge the system, expressed as a percentage. For example, a round trip efficiency of 80% means that a system is able to deliver 80% of the energy that was used to charge the system to the end user. It is important to note that no energy storage system is 100% efficient and that there is always a loss of energy in the storage/delivery process.

In November 2021, Energy Vault launched Energy Vault Solutions (EVS) to provide a technology neutral energy storage management and integration platform. The EVS platform is being designed to enable the integration of different energy assets and their economic dispatching by using artificial intelligence (AI) and software optimization algorithms.

Industry Overview

The global increase in renewable energy generation is driving demand for energy storage. Key drivers of the renewable energy market include the need to decrease reliance on fossil fuels given ongoing growth in harmful CO2 emissions and to accelerate the shift to now affordable renewable sources that require storage to manage the intermittency of renewable generation.

Demand for clean energy is growing globally, with renewables expected to generate 90% of total energy by 2050. Energy storage deployments are expected to grow to 300 gigawatt hours by the year 2025 and at a 20% compounded annual growth rate to approximately 830 gigawatt hours by 2030. Both governmental mandates and companies focused on reducing energy use, cost and emissions will help drive the shift to renewable sources of power. Energy Vault is well-positioned to capitalize on this opportunity through competitive pricing, scalability, and environmentally-friendly attributes of its energy storage solutions.

Many utilities around the world have publicly stated their carbon emissions reduction and sustainability goals which incorporate strategies to support a circular economy. Legacy power generation and renewable technologies also have specific challenges to address such as limited availability of required geology, supply chain demand issues, environmental liability, and safety risk.

The renewable energy storage market is currently dominated by pumped hydroelectric storage, which has an approximate 90% market share. While pumped hydroelectric energy storage has proven to have long-life cycle and quick response times to deploy energy when needed, pumped hydroelectric energy storage solutions require large amounts of land, need to be located near a water source, are not scalable once built,

167

TABLE OF CONTENTS

and often use carbon-intensive materials that are harmful to the environment. Pumped hydroelectric energy storage is further challenged to meet the expected market growth as there are few remaining sites available with naturally occurring low and high reservoirs, and the cost and environmental impact of creating man-made reservoirs is high.

Lithium-ion battery storage currently has an approximate 5% market share. Lithium-ion battery storage, which is also used in consumer products and electric vehicles, is a widely accepted form of utility scale energy storage. However, some chemistry of lithium-ion battery technology requires scarce raw materials (such as cobalt) for battery production which can be subject to periodic supply chain challenges and carry a high-carbon footprint for shipping and production. In addition, battery chemistries degrade over time, contain hazardous materials, are associated with disposal issues and pose safety and fire risks.

Certain other forms of renewable energy storage technology, including geothermal and flow batteries, require relatively high capital investment and have high operating costs, have relatively lower efficiency levels, are not modular, and have geological constraints. Other mechanical methods, such as compressed air, fly wheels, and other gravity-based solutions, generally have high carbon footprints, are dependent on specific land topography and/or underground geology, have lower efficiency, have high operating costs, and are not scalable or modular.

Energy Vault Solutions

Energy Vault’s storage solutions will allow utilities, independent power producers, and large energy users to manage their power portfolios and efficiently dispatch power. Importantly, given the intermittency of variable renewable energy sources such as wind and solar generation, Energy Vault’s system will complement variable renewable energy generation by allowing for charging and storage of energy during periods of high generation, and dispatch of that stored energy during periods of high demand and when energy is not otherwise being generated. Energy Vault solutions can act as a stand-alone energy storage solution to achieve power reserves for any energy generation source. Energy Vault’s gravity-based storage systems do not rely on the land topography or geology of pumped-hydro, can be built to meet local building code requirements, and can either be co-located with generation sources, or connected to the grid as stand-alone storage to support dispatchability, grid stability, and to help defer grid upgrade investments.

Energy Vault’s gravity-based systems are designed using proprietary crane/elevators and motor/generator infrastructure to orchestrate autonomously balanced net energy storage and energy distribution by using motor/generators to lift and lower mobile masses. When excess energy is on the grid, the systems’ motors will lift the mobile masses to an elevated position where they store potential energy. When energy is needed, the motors act as generators and the system will discharge electricity generated from the kinetic energy of the controlled gravitational lowering of the mobile masses. Energy Vault’s EVx modular solution is economically viable for both short (2-4 hours), medium (4-10 hours) and long (ten or more hours) durations and is the building block for the EVRC platform that can be built out in 10MWh increments that can scale to multi-GW-hour storage capacity.

EV1 Tower — First Generation Design

Energy Vault introduced the first generation EV1 six-arm crane tower design. In July 2020, Energy Vault completed mechanical construction of the first-of-its-kind, commercial demonstration (CDU) unit located in Arbedo-Castione, Switzerland. The system was connected to the Swiss national electricity grid and is being utilized for continued testing and software improvements.

EVx Platform

Building on its experience with the CDU, Energy Vault has designed its EVx system. Energy Vault has worked with several of the largest utilities and energy companies in the world to optimize its gravity energy storage platform for improved flexibility and to address potential customers’ evolving needs for storage duration and operational characteristics. The new platform is designed to be up to 45% lower in height than the EV1 and utilizes the same mobile mass weights that can be made from local soil, waste, and remediation material for beneficial re-use as energy storage. The EVx platform is designed to be a scalable, modular product line starting from 40MWh to multi-GWh to address grid resiliency needs in shorter durations while supporting longer duration and power needs in the event of power outages or powering industrial processes over long periods

Energy Vault Resiliency Center

Energy Vault Resiliency Center is a scalable, gigawatt hour scale product line designed to address grid resiliency needs to manage energy disruptive climate events such as wildfire or extreme weather. The EVx is the building block of the modular 10MWh infrastructure used to build the EVRC level capacity system. The EVRC is a larger capacity system than the EVx system and is designed for grid resiliency. Using the EVx design as a building block, the EVRC can be custom designed and built out in 10MWh increments that can scale to multi-GW-hour storage capacity to meet the energy storage needs for grid-scale deployment.

Strategy

Energy Vault intends to leverage its technology, competitive strengths, and remediation opportunity to establish its EVx and EVRC systems as viable solutions for short, medium and long-term renewable energy storage solutions through the following strategies:

International Market Growth: Energy Vault’s outsourced assembly and construction model supports growth, local jobs, and global execution. The strategy involves establishing regional and country level

infrastructure to support local deployments. To enable rapid adoption, initial deployments will be focused across multiple continents to have regional proof-points of the technology.

Further Expand Products and Project Related Services: Energy Vault will continue to develop its EVx platform and explore further expansion of energy storage technologies, products and project related services that are necessary to support the evolution of energy storage.

Establishing a Circular Economy in the Energy Sector: Energy Vault will continue to develop its unique approach to the circular economy by further developing remediation and recycling opportunities for energy waste materials for beneficial reuse in energy storage solutions. The two main areas Energy Vault is currently exploring include:

Coal Ash Remediation Opportunity: Energy Vault continues to engage with fossil fuel energy producers to explore how coal ash that otherwise must be disposed of might be repurposed for reuse in energy storage; and

Wind Power and Gravity Storage Circular Economy: Global clean energy-producing wind power plant capacity increased by 53% in 2020. Energy Vault believes this growth will continue in the coming years. There is a need to identify circular solutions for when these plants are decommissioned and dismantled. Through the announced agreement with Enel Green Power, Energy Vault intends to recycle waste materials generated by decommissioning wind turbine blades at end of life and to apply a circular economy approach toward managing the entire wind power value chain.

Focus on Software Innovations: Energy Vault will continue research and development efforts in core areas of predictive analytics, artificial intelligence (AI), industrial internet of things, control systems for improving how energy storage systems dispatch power, grid services, and network-enabled energy operations. Energy Vault will pursue these technologies to enable it to optimize round-trip efficiency, to streamline operations and maintenance, and to reduce the cost of storing energy. Through EVS, Energy Vault is in the early stages of exploring the potential for offering a digital platform that could help energy storage businesses make decisions on when to charge their systems and when to sell their power, as a standalone product.

Exploration of Co-Active Use Cases: In addition to its core energy storage technology, Energy Vault is currently exploring alternative use case opportunities for energy intensive industries such as vertical farming, data centers, blockchain mining, direct air carbon capture, that may be able to benefit from existing infrastructure, including physical enclosure and electrical supply.

Competitive Strengths

Energy Vault has designed its EVx and EVRC systems to provide the following advantages compared to other forms of utility scale energy storage:

Economics: Energy Vault’s EVx system can be built with a competitive levelized cost of storage compared to currently available technologies in the short and medium- to long-duration storage market. The unique design leverages a mature global supply chain ecosystem which can offer a scalable solution at lower operational costs.

Performance: Unlike chemical battery technologies, which begin to lose storage capacity immediately with cycling and require augmentation at frequent intervals, Energy Vault’s storage medium, composite blocks or mobile masses, do not lose their storage capacity over time and therefore mitigates the need for additional capital investment to maintain the storage medium. At 80%-85% round trip efficiency, millisecond response and an approximate 50% per second ramp rate, Energy Vault’s EVx system also competes well with current shorter duration energy storage technologies on performance.

Duration: The EVx and EVRC product designs enable Energy Vault to address medium and long duration storage of 4-12 or more hours to meet uniquely a large and critical market segment that cannot efficiently utilize renewable energy today. The EVx is a modular and flexible design that allows for a wide range of duration capabilities aligning with the market demand for 2-12 hour or more discharge duration.

TABLE OF CONTENTS

Energy Vault’s EVRC is a larger capacity system designed to support grid resiliency and to provide emergency backup power in the instance of extreme weather and energy system outages.

Sustainability: Energy Vault’s gravity energy storage is based on traditional pumped hydroelectric energy storage but was designed to remove the geological constraints and ecological disruption of pumped hydroelectric energy storage. Energy Vault’s mobile masses are designed to be more environmentally friendly than chemical batteries with toxic chemistries and environmentally disruptive mining requirements for raw materials. The process for manufacturing mobile masses, onsite, can use various waste material, including energy waste (materials that might otherwise be deposited in landfills), and therefore offers potential customers both an energy storage solution and a waste remediation solution.

Local Production: Constructing the systems at the location where the hazardous waste originates, such as coal ash at a decommissioned coal plant site, is intended to mitigate the environmental issues associated with shipping and storing hazardous waste. By sourcing the materials for its mobile masses directly at the project site, Energy Vault’s production design model aims to reduce the supply chain and transportation costs and reduce carbon emissions from the transport.

Project Delivery

Energy Vault’s project delivery strategy relies on engineering, procurement, construction (EPC) firms to construct Energy Vault projects, under Energy Vault supervision with dedicated teams tasked with project management.

Manufacturing and Customer Support

Energy Vault’s manufacturing, assembly and construction model is designed to support rapid growth, local jobs, and global execution. The strategy involves establishing regional and country level infrastructure to support local deployments through the EPC contracting model. For manufacturing, Energy Vault will continue to collaborate with leading materials science, power electronics, motor generators and electromechanical systems providers. The Enel Green Power collaboration aims to integrate recycling of decommissioned wind turbine blades in mobile mass production. Energy Vault has agreements with other third parties to provide the polymers and other composite material technology for manufacturing the mobile masses.

Energy Vault plans to provide maintenance, customer support, and repair services for the entire system, including performance of regular preventative maintenance.

Research and Development

In 2018, Energy Vault built a concept demonstration unit in Biasca, Switzerland to assess the feasibility of the mechanical performance, efficiency, and automated software orchestration of the gravity-based energy storage concept. This effort included concept development and testing of mix designs for future full-scale mobile masses. Energy Vault utilized this phase to demonstrate the technology and identify key technical challenges. Energy Vault completed various engineering studies, including seismic shake table stability analysis, accelerated mobile masses long-duration testing, and reliability studies. Energy Vault also continued further software testing, which included simulations for factors such as varying weather conditions, crane deflection, cable elongation, and pendulum effect.

Further efforts to improve the technology are currently underway at the CDU in Ticino, Switzerland. Energy Vault has also initiated the process to evaluate the regulatory acceptability of beneficial reuse of coal ash waste materials in gravity mobile masses manufacturing. To this end, Energy Vault has conducted trial mix design and materials testing with a third-party partner and contracted a testing agency to provide the third-party leach testing of the various mix designs. Early results indicate that the beneficial reuse of coal ash in Energy Vault’s mobile masses can be an accepted application in accordance with both federal and state environmental requirements.

Sales and Marketing

Energy Vault’s marketing strategy is designed to build Energy Vault into a leadership brand that supports the shift from being a supplier of technology to a respected and sought-after customer partner to maximize growth. Energy Vault’s marketing strategy includes the following:

171

TABLE OF CONTENTS

Brand Visibility, Awareness, and Education: Through its branding and web marketing Energy Vault communicates with a broad set of stakeholders and works to establish leadership expertise to lay the foundation for qualified customer and supplier interaction.

Drive Demand: Energy Vault corporate outreach strategy is designed to drive demand for lead generation. We work to achieve this through web marketing and initiatives designed to accelerate the customer adoption process.

To achieve this, Energy Vault employs the following:

Integrated Marketing: Energy Vault takes a targeted approach to strategic integrated marketing campaigns that are designed to maximize available budget while elevating its voice within the marketplace, generate leads and close deals.

Lead Generation Model: Energy Vault’s campaigns are designed to drive “a call to action” on its website to capture leads. Energy Vault also engages in a range of other traditional marketing activities such as tradeshows and events, internal / partner sources and various digital marketing activities such as website, search engine optimization, social media integration, online events and forums.

Sales Model: The Energy Vault sales model is designed to serve the full scope of the addressable market by offering its customers a choice of two programs. Under the first program, Storage Asset Owners, the customer would own both the energy storage system and the service the system provides (the energy storage and dispatch of electricity). Energy Vault anticipates that this program will constitute the substantial majority of future sales and that utility companies, independent power producers and industrial customers that consume large amounts of power or are making a transition to 24/7 renewable power may be interested in being Storage Asset Owners. Under the second program, Storage Service Customers, customers such as community choice aggregators, independent power producers and utility companies would sign long-term power purchase agreements and/or tolling agreements to purchase power on a fixed dollar per kilowatt monthly or hourly basis while Energy Vault and potentially other equity co-investors would retain an ownership interest in the system. In this business model, power could also be sold on a merchant market basis to take advantage of large changes in the price of electricity at different times of day.

Target Customers

Energy Vault’s target customers include independent power producers, government organizations, utilities, grid operators, as well as industrial and commercial organizations with sizeable electricity needs. Because of the unique advantages of gravity energy storage, Energy Vault believes there can be significant demand for its systems to help address the large growth in global energy storage capacity.

Energy Vault has eight executed letters of intent or purchase orders and an energy storage agreement with DG Fuels LLC, or the DG Fuels Agreement, which contemplates additional sales agreements relating to the proposed projects. In addition, Energy Vault is also in the early phases of discussions with 18 other opportunities.

Each purchase order and letter of intent provides the customer with the right to terminate for any reason or no reason in its sole discretion without any liability, payment or penalty. Accordingly, there can be no assurance that any such arrangement will become a binding order, sale or committed off-take agreement or otherwise be completed on the terms described or at all. Moreover, the DG Fuels Agreement may not yield an executed sales agreement at all or as we expect. In the event an agreement is terminated, Energy Vault may incur significant expenses which it may not recover, which could have a material adverse effect on its operating results and cash flow.

In October 2021, Energy Vault entered into the DG Fuels Agreement, which has the potential to generate up to $520 million in revenue across three projects, the first of which is expected to commence in mid-2022. The timing of the commencement of and payments under each project are subject to the execution of a sales agreement relating to such project, and the revenue from each project will be dependent upon the agreed upon size of the project, and the timing of such project and the performance of DG Fuels. The receipt and timing of any revenue recognition and payments from the DG Fuels Agreement will be subject to the timing and execution of sales agreements and the performance by its counterparty under such sales agreement

172

TABLE OF CONTENTS

for Energy Vault’s energy storage systems. Any event or circumstance that delays or impairs its or its counterparty’s performance could materially adversely affect the amount or timing of revenue generated under the DG Fuels Agreement, and such revenue, if any, may be materially less than what Energy Vault expects. There can be no assurance that sales agreements will be executed with respect to any of the projects, that any of such projects are completed, or that Energy Vault will generate all $520 million of revenue, or any meaningful part thereof, under the DG Fuels Agreement or on the timeline it expects.

Additionally, in December 2021, Energy Vault entered into a Memorandum of Understanding with BHP Manganese Australia Pty. Ltd. (“BHP”) focused on studying the application of Energy Vault's technology to support power supply and energy storage at certain BHP operations while exploring opportunities for new applications relevant to BHP's business. There can be no assurance that a definitive agreement with BHP will be executed or that Energy Vault will generate any revenue from this collaboration.

Competition

The energy industry is highly competitive, and Energy Vault expects competition in energy storage technology to intensify due to a regulatory push for lower-carbon energy sources such as intermittent sources such as wind and solar, continuing globalization, and consolidation in the energy industry. Energy Vault believes that the principal competitive factors in the energy storage market include:

•

levelized cost of energy delivered;

•

safety, reliability and quality;

•

product performance;

•

historical track record and references for customer satisfaction;

•

experience in utilizing the energy storage system for multiple stakeholders;

•

innovation across a variety of technologies;

•

comprehensive solution from a single provider;

•

ease of integration; and

•

seamless hardware and software-enabled service offerings.

Energy Vault’s competitors are focused on the development and marketing of solutions based on technologies other than our gravity-based energy storage technology. Many of Energy Vault’s competitors are focused on solutions based on lithium-ion battery technology although many other technologies, including thermal storage, chemical storage and hydrogen energy storage, are evolving and are in the early stages of development.

Energy Vault’s key competitors include battery vendors and long duration energy storage system manufacturers. Battery vendors with whom Energy Vault competes such as Tesla, Inc., Fluence Energy, Inc., LG Chem, Ltd., Samsung Electronics Co., Ltd and Contemporary Amperex Technology Co. Limited have already commercialized their respective energy storage solution products. Additionally, long duration storage system manufacturers who have each announced plans and demonstrated prototypes of products that would compete in the energy storage market, include ESS Inc., Eos Energy Enterprises Inc., Hydrostor Inc. and Primus Power. Companies such as Tesla, Inc., Fluence Energy, Inc. and Wartsila Corporation are also developing energy management software.

Some of our current and potential competitors have longer operating histories and greater financial, technical, marketing and other resources than Energy Vault does. These factors may allow Energy Vault’s competitors to respond more quickly or efficiently than Energy Vault can to new or emerging technologies. These competitors may engage in more extensive research and development efforts, undertake more far-reaching marketing campaigns and adopt more aggressive pricing policies, which may allow them to more effectively compete for new energy storage projects.

Energy Vault believes that its gravity-based energy storage solutions, including the EVx and EVRC platforms, will be differentiated from those of its competitors because Energy Vault’s systems minimize

173

TABLE OF CONTENTS

environmental and supply chain risks and geological constraints of some of the energy storage technologies on the market today. For that reason, Energy Vault believes it is well-positioned to compete successfully in the evolving market for energy storage solutions.

Intellectual Property

Energy Vault relies on a combination of patent, trademark, copyright, unfair competition, and trade secret laws, as well as confidentiality procedures and contractual restrictions with its employees, contractors and third parties, to establish, maintain and protect its proprietary rights. Energy Vault’s success depends in part upon its ability to obtain, maintain and enforce proprietary protection for Energy Vault’s products, technology, and know-how, to operate without infringing the proprietary rights of others, and to prevent others from infringing Energy Vault’s proprietary rights.

Energy Vault has developed a patent portfolio to protect elements of its proprietary technology. As of September 20, 2021, Energy Vault had four issued patents and nine patent applications pending in the U.S and 17 patent applications pending in other countries throughout the world. Energy Vault’s issued patents are expected to expire in 2039 and 2040.

Energy Vault’s intellectual property encompasses a diverse mix of patents with respect to its proprietary systems and software. These patents and patent applications relate to the following broad categories:

•

Energy Storage System and Method

•

Energy Storage System Using Non-Stacking Weights

•

Lift Drive System for Energy Storage and Delivery System

Energy Vault primarily relies on copyright, trade secret laws, confidentiality procedures and contractual restrictions to protect its software. Energy Vault also pursues the registration of its domain names and trademarks and service marks in the United States.

Energy Vault intends to continue to assess regularly opportunities for seeking patent protection for those aspects of its technology, designs and methodologies that Energy Vault believes provide a meaningful competitive advantage. However, Energy Vault’s ability to do so may be limited until such time as it is able to generate cash flow from operations or otherwise raise sufficient capital to continue to invest in its intellectual property. For example, maintaining patents in the United States and other countries requires the payment of maintenance fees which, if Energy Vault is unable to pay, may result in loss of its patent rights. If Energy Vault is unable to do so, its ability to protect its intellectual property or prevent others from infringing on its proprietary rights may be impaired.

Government Regulation and Compliance

Although Energy Vault is not regulated as a utility, federal, state and local government statutes and regulations concerning electricity heavily influence the market for its product and services. These statutes and regulations often relate to electricity pricing, net metering, incentives, taxation, competition with utilities and the interconnection of customer-owned electricity generation. In the U.S., governments continuously modify these statutes and regulations. Governments, often acting through state utility or public service commissions, change and adopt different rates for commercial customers on a regular basis. These changes could affect Energy Vault’s ability to deliver cost savings to future customers for the purchase of electricity.

Several states have an energy storage mandate or policies designed to encourage the adoption of storage. Storage installations are supported in certain states by state public utility commission policies that require utilities to consider alternatives such as storage before they can build new generation facility. In February 2018, the Federal Energy Regulation Commission (FERC) issued Order 841 directing regional transmission operators and independent system operators to remove barriers to the participation of storage in wholesale electricity markets and to establish rules to help ensure storage resources are compensated for the services they provide. An appeal of Order 841 filed by utility trade associations and other parties challenging the extent of FERC’s jurisdiction over storage resources connected to distribution systems (among other issues) is currently pending before the U.S. Court of Appeals for the D.C. Circuit.

174

TABLE OF CONTENTS

Each of Energy Vault’s installations or customer installations must be designed, constructed, and operated in compliance with applicable federal, state and local regulations, codes, standards, guidelines, policies and laws. To install and operate energy storage systems on its platform, Energy Vault, its customers or its partners, as applicable, are required to obtain applicable permits and approvals from local authorities having jurisdiction to install energy storage systems and to interconnect the systems with the local electrical utility.

Energy storage systems require interconnection agreements from the applicable local electricity utilities in order to operate. In almost all cases, interconnection agreements are standard form agreements that have been pre-approved by the local public utility commission or other regulatory body with jurisdiction over interconnection agreements. As such, no additional regulatory approvals are typically required once interconnection agreements are signed.

Energy Vault’s operations are subject to stringent and complex federal, state and local laws and regulations governing the occupational health and safety of its employees and wage regulations. For example, Energy Vault is subject to the requirements of the federal Occupational Safety and Health Act, as amended, and comparable state laws that protect and regulate employee health and safety.

There are government regulations pertaining to the disposal of hazardous materials. Energy Vault and its suppliers, as applicable, are required to comply with these regulations to sell its systems into the market.

Employees

Energy Vault stakeholders and employees have a shared passion to combat climate change through innovation in energy storage technologies. Energy Vault’s employees typically have significant industry experience in their respective areas of focus. As of September 30, 2021, Energy Vault employed 41 full-time employees and ten part-time employees, based primarily in its offices in Lugano, Switzerland and its offices in Westlake Village, California. To date, Energy Vault has not experienced any work stoppages and considers its employee relations to be in good standing. None of Energy Vault’s employees are either represented by a labor union or subject to a collective bargaining agreement.

Properties

Energy Vault has offices in Westlake Village, California and Lugano, Switzerland, with the Switzerland office serving as Energy Vault’s international headquarters. The Lugano facility is under a month-to-month lease. The Westlake Village facility comprises approximately 7,700 square feet, and Energy Vault’s current lease at the Westlake Village office expires at the end of 2021 with the option to renew.

Legal Proceedings

Energy Vault has been and continues to be involved in legal proceedings that arise in the ordinary course of business, the outcome of which, if determined adversely to Energy Vault, would not individually or in the aggregate have a material adverse effect on Energy Vault’s business, financial condition, and results of operations. From time to time, Energy Vault may become involved in additional legal proceedings arising in the ordinary course of its business.

The salaries and target bonus opportunities of Energy Vault’s named executive officers are typically reviewed annually and adjusted when the Energy Vault Board or Energy Vault’s compensation committee determines it is appropriate. Effective as of the closing of the Business Combination, the Energy Vault Board plans to issue bonuses to the named executive officers upon meeting performance objectives for the 2021 fiscal year on or prior to March 2022.

Historically, the equity compensation granted to Energy Vault’s named executive officers has consisted of restricted stock awards or RSUs. For a description of such equity awards outstanding as of December 31, 2020, please see the “Outstanding Equity Award at 2020 Year-End” table below.

2020 Energy Vault Director Compensation

Except with respect to Mr. Piconi, Energy Vault currently has no formal arrangements under which directors receive compensation for their service on Energy Vault’s board of directors or its committees.

Post-Closing Director Compensation

Following the Business Combination, the Combined Company is expected to implement a compensation program for its non-employee directors.

Executive Compensation

Following the Business Combination, the Energy Vault Compensation Committee will oversee the compensation policies, plans, and programs and review and determine compensation to be paid to executive officers, directors and other senior management, as appropriate. Energy Vault intends to develop an executive compensation program that is designed to align compensation with its business objective of transforming the energy sector around the world and the creation of stockholder value, while enabling the Combined Company to attract, retain, and reward individuals who contribute to the accomplishment of the business objective and long-term success of the Combined Company. Decisions on the executive compensation program will be made by the Energy Vault Compensation Committee.

Energy Vault believes it is important to maintain a strong link between executive incentives and the creation of stockholder value; therefore, the equity-based component of the executive compensation program has been and will continue to be an important element in executive compensation packages. The equity component not only attracts, motivates and retains high-quality executives but also encourages performance that contributes to maximizing stockholder value. Formal compensation programs and guidelines have not been determined yet but will be developed to support the growth of the Combined Company.

Employment Agreements

The Combined Company intends to enter into Employment Agreements with the Key Executives, which will provide the terms and conditions of the Key Executives’ employment with the Combined Company following the consummation of the Business Combination. The parties are discussing the terms of the Employment Agreements.

Equity Compensation

As discussed above under Proposal No. 3 (Equity Incentive Plan Proposal), the Novus Board is expected to approve and adopt the 2022 Plan, which, subject to the approval of Novus’s stockholders, would authorize the grant of equity awards to eligible individuals, including the named executive officers, following the consummation of the Business Combination.

ENERGY VAULT MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of the financial condition and results of operations of Energy Vault, Inc. and its subsidiary should be read together with the section of this proxy statement/prospectus titled “Selected Historical Consolidated Financial Information of Energy Vault” and the unaudited and audited consolidated financial statements as of September 30, 2021 and for the nine months ended September 30, 2021 and 2020 and as of and for the years ended December 31, 2020 and 2019, respectively, together with related notes thereto, included elsewhere in this proxy statement/prospectus. The discussion and analysis should also be read together with the section of this proxy statement/prospectus titled “Information About Energy Vault” and the unaudited pro forma condensed combined financial information as of and for the nine months ended September 30, 2021 and for the year ended December 31, 2020 (in the section of this proxy statement/prospectus titled “Unaudited Pro Forma Condensed Combined Financial Information”). The following discussion contains forward-looking statements that involve risks, uncertainties and assumptions. See the section titled “Cautionary Note Regarding Forward-Looking Statements.” Actual results and timing of selected events may differ materially from those anticipated in the forward-looking statements as a result of various factors, including those set forth under the section titled “Risk Factors — Risks Related to Energy Vault’s Business and Industry” or elsewhere in this proxy statement/prospectus. As used in this section, unless the context suggests otherwise, “we,” “us,” “our,” the “Company” or “Energy Vault” refer to Energy Vault, Inc. and its subsidiary prior to the consummation of the Business Combination.

Our Business

Energy Vault develops sustainable, grid-scale energy storage solutions designed to advance the transition to a carbon free, resilient power grid. Energy Vault’s mission is to accelerate the decarbonization of our economy through the development of sustainable and economical energy storage technologies. To achieve this, Energy Vault is developing a proprietary gravity-based energy storage technology. Energy Vault is also designing proprietary energy management software based on artificial intelligence (AI), advanced optimization algorithms designed to control and optimize entire energy systems and a flexible energy storage integration platform suitable for storage technologies of many durations. Energy Vault’s product platform aims to help utilities, independent power producers, and large energy users significantly reduce their levelized cost of energy while maintaining power reliability.

184

TABLE OF CONTENTS

Center (EVRC) solutions combine advanced materials science and proprietary machine-vision software to autonomously orchestrate the charge, storage, and discharge of electricity in grid-scale applications. To achieve this, Energy Vault synthesized technologies from four established industries: crane/elevators, shipping, motor/generator, and materials science. Combining potential and kinetic energy cycles, Energy Vault's systems are automated with advanced computer control and machine vision software to create a gravity energy storage innovation designed to meet the market demand for 2-12 hours of storage duration. Energy Vault’s EVx and EVRC systems are designed to serve economically both higher power/shorter duration applications with ancillary services from 2-4 hours, while scaling to serve medium (4-10 hours) and long duration (ten or more hour) requirements.

In November 2021, Energy Vault launched Energy Vault Solutions (EVS) to provide a technology neutral energy storage management and integration platform. The EVS platform enables the integration of different energy assets and their economic dispatching by using artificial intelligence (AI) and software optimization algorithms.

The Energy Vault sales model is designed to serve the full scope of the addressable market by offering its customers a choice of two programs. Under the first program, Storage Asset Owners, the customer owns both the energy storage system and the service, that the system provides (i.e. the energy storage and dispatch of electricity). Energy Vault anticipates that this program will constitute the substantial majority of future sales and that utility companies, independent power producers and industrial customers that consume large amounts of power or are making a transition to 24/7 renewable power may be interested in being Storage Asset Owners. Under the second program, Storage Service Customers, customers such as community choice aggregators, independent power producers and utility companies would sign long-term power purchase agreements and/or tolling agreements to purchase power on a fixed dollar per kilowatt monthly or hourly basis while Energy Vault and potentially other equity co-investors retain an ownership interest in the system. In this business model, power could also be sold on a merchant market basis to take advantage of large changes in “time of day” pricing of electricity.

In October 2021, Energy Vault entered into an Energy Storage System Agreement (“Agreement”) with DG Fuels LLC (“DG Fuels”). Under the terms of the Agreement, Energy Vault agreed to provide up to 1.6 gigawatt hours (GWh) of energy storage to support DG Fuels across multiple projects, the first of which is currently projected to commence construction in mid-2022 and is currently expected to be a 500 megawatt hour project (MWh) in Louisiana. In addition, on October 29, 2021, the Company agreed to invest $1 million in DG Fuels pursuant to a convertible promissory note with DG Fuels.

The Business Combination

Energy Vault entered into the Business Combination Agreement on September 8, 2021. If the Business Combination is approved by Novus’s stockholders, and the conditions outlined in the Business Combination Agreement and other customary closing conditions are satisfied or waived, Energy Vault will merge with Merger Sub, with Energy Vault surviving as a wholly-owned subsidiary of Novus, which will change its name to “Energy Vault Holdings, Inc.”

185

TABLE OF CONTENTS

The Business Combination is anticipated to be accounted for as a reverse recapitalization. Energy Vault will be the deemed acquiror for accounting purposes and the Combined Company will be the successor SEC registrant, meaning that Energy Vault’s financial statements for previous periods will be disclosed in the Combined Company’s future periodic reports filed with the SEC. Under this method of accounting, Novus will be treated as the acquired company for financial statement reporting purposes. Upon consummation of the Business Combination, and the closing of the PIPE, the most significant change in the Combined Company’s future reported financial position and results are expected to be an estimated increase in cash and cash equivalents to approximately $238.0 million in a maximum redemption scenario and to $456.4 million in a minimum redemption scenario. In either case, approximately $100.0 million in gross proceeds from the PIPE will be contributed to the Combined Company. Total direct and incremental transaction costs of Novus and Energy Vault are estimated at approximately $49.2 million and will be treated as a reduction of the cash proceeds with $46.6 million deducted from additional paid-in capital for equity issuance costs and the remaining balance is expensed through accumulated deficits. See the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” for further information.

As a result of the Business Combination, Energy Vault will become the successor to a publicly traded company, which will require the hiring of additional personnel and implementation of procedures and processes to comply with public company regulatory requirements and customary practices. The Combined Company will be classified as an Emerging Growth Company, as defined under the Jumpstart Our Business Startups Act (the “JOBS Act”), which was enacted on April 5, 2012. Upon completion of the Business Combination, the Combined Company will be provided certain disclosure and regulatory relief, provided by the SEC by virtue of the JOBS Act, as an Emerging Growth Company.

Key Factors and Trends Affecting our Business

We believe that our performance and future success depend upon several factors that present significant opportunities for us but also pose risks and challenges including those discussed below and in the section of this proxy statement/prospectus titled “Risk Factors.”

Product Development and Deployment Plan

Our cost projections are heavily dependent upon raw materials (such as steel), equipment (such as motors, inverters and power electronic devices) and technical and construction service providers (such as engineering, procurement, construction firms). The global supply chain, on which Energy Vault relies, has been significantly impacted by the COVID-19 pandemic and other economic uncertainties, resulting in potential significant delays and cost fluctuations, particularly with respect to microchips and many other raw materials that are within the motor and power electronic supply chains. These future timing and financial developments may impact Energy Vault’s performance from both a deployment and cost perspective.

Currently, the only operating energy storage system utilizing Energy Vault’s technologies is the CDU which Energy Vault continues to use for testing and software improvement. Building on its experience with the CDU, Energy Vault has designed its EVx system. The EVx platform is designed to be a scalable, modular product line starting from 40MWh to multi-GWh to address grid resiliency needs in shorter durations while supporting longer duration and power needs in the event of power outages or powering industrial processes over long periods. Using the EVx design as a building block, the EVRC can be custom designed and built out in 10MWh increments that can scale to multi-GW-hour storage capacity to meet the energy storage needs for grid-scale deployment. There are no commercial installations of Energy Vault’s EVx system or EVRC platform at this time.

Energy Storage Industry

Our future revenue growth will be directly tied to the continued adoption of renewable energy storage systems. As the sector is relatively nascent, we expect the markets for renewable energy storage to increase. Furthermore, our systems rely on an alternative technology to the dominant and accepted storage technologies

186

TABLE OF CONTENTS

such as lithium-ion, flow batteries and thermal storage. Our business depends on the acceptance of our products, including the EVx systems, in the marketplace. Even if renewable energy and energy storage become more widely adopted than they have been to date, potential customers may choose energy storage products from our competitors that are based on technologies other than our gravity-based energy storage technology.

COVID-19

The spread of the COVID-19 has caused an economic downturn on a global scale, as well as significant volatility in the financial markets. Government reactions to the public health crisis with mitigation measures have created significant uncertainties in the U.S. and global economies. The COVID-19 pandemic had caused delays in the construction of the CDU in Switzerland due to Government-mandated temporary stay-at-home and quarantine orders; however, it did not significantly impact Energy Vault’s other core functions such as research and development and capital raising. Due to the pandemic related uncertainties in global markets and specific restrictions announced by The Canton Government of Ticino in March and April 2020, Energy Vault implemented actions to reduce its operating expense run rate through temporary salary reductions and other discretionary expense reductions. CDU component deliveries into the testing site in Arbedo Castione were also delayed due to the Swiss border being closed and due to the worksite being shut in compliance with the March 2020 lockdown. Furthermore, the Canton Health and Safety Department of Ticino, Switzerland ordered the hiring of a Health and Safety Manager in order to resume onsite operations of the CDU. The extent to which the COVID-19 pandemic impacts Energy Vault’s business, operations and financial results will depend on numerous evolving factors that management may not be able to accurately predict. The ultimate outcome of these matters is uncertain and, accordingly, the impact on our financial condition or results of operations is also uncertain.

Components of Results of Operations

Revenue

To date, we have not recognized any revenue. We expect to earn revenue from the sale of energy storage solutions, under three complementary sales programs based on customer preferences. Under the first program, Storage Asset Owners, the customer owns both the energy storage system and the service, that the system provides (i.e., the energy storage and dispatch of electricity). Energy Vault anticipates that this program will constitute the substantial majority of future sales and that utility companies, independent power producers and industrial customers that consume large amounts of power or are making a transition to 24/7 renewable power may be interested in being Storage Asset Owners. Under the second program, Storage Service Customers, customers such as community choice aggregators, independent power producers and utility companies would sign long-term power purchase agreements and/or tolling agreements to purchase power on a fixed dollar per kilowatt monthly or hourly basis while Energy Vault and potentially other equity co-investors would retain an ownership interest in the system. Under the third program, the customer enters into a Software as a Service (SaaS) agreement with Energy Vault, and is granted access to Energy Vault’s Energy Management System that helps the economic dispatching of its energy storage and generation assets. We intend to finalize our revenue recognition policies relating to the programs once we finalize definitive agreements with our future customers. We have not recognized any revenue for the years ended December 31, 2020, and 2019 or for the nine months ended September 30, 2021.

Operating expenses

Sales and marketing expenses

Sales and marketing expenses consist primarily of expenses relating to professional service costs, trade shows, marketing and sales related promotional materials, public relations expenses, website operating and maintenance costs, and stock-based compensation expenses for marketing, sales personnel, and related support teams. We expect that our sales and marketing expenses will increase over time as we continue to hire additional personnel to support the overall growth in our business.

Research and development expenses

Research and development expenses consist primarily of internal and external expenses incurred in connection with our research activities and development programs that include materials costs directly

187

TABLE OF CONTENTS

related to the product development, testing and evaluation costs, construction costs including labor and transportation of material, overhead related costs and other direct expenses consisting of stock-based compensation and consulting expenses relating to study of product safety, reliability and development. We expect our research and development costs to increase for the foreseeable future as we continue to invest in these activities to achieve our product design, engineering, and development roadmap.

General and administrative expenses

General and administrative expenses consist of information technology expenses, legal and professional fees, travel cost, personnel-related expenses for our corporate, executive, finance, and other administrative functions including expenses for professional and contract services. Personnel related expenses consist of salaries, benefits, and stock-based compensation expense. To a lesser extent, general and administrative expense includes depreciation, insurance costs, rent, office expenses and maintenance costs. We expect our general and administrative expenses to increase in the foreseeable future as we hire personnel to meet the growth of our business, and as a result of operating as a public company, including compliance with the rules and regulations of the SEC, legal, audit, additional insurance expenses, investor relations fees and other administrative and professional services.

Inventory write-down

Energy Vault began development of a prototype of the EV1 in March 2020, resulting in the CDU, an EV1 Tower, which was connected to the Swiss national grid in July 2020. Thereafter, through design improvements and refinements of its technology, Energy Vault formally launched the new EVx platform in 2021. The inventory write-down reported for the nine months ended September 30, 2021, is attributable to losses incurred due to a damaged component relating to the CDU. Additionally, other components, which were not previously installed, remain in inventory and were adjusted to their estimated net realizable value as Energy Vault intends to eventually sell them. As the EVx system is being developed, the remaining components of the CDU have been reclassified as a demonstration and testing equipment in plant and equipment category of the condensed consolidated balance sheet.

Other income (expense)

Change in fair value of derivative

The gain/(loss) on revaluation of embedded derivatives consists of periodic fair value adjustments associated with the Series B Convertible Preferred Stock issuance right derivative liability.

Interest expense

Interest expense consists primarily of interest related to finance leases and non-cash interest expense related to the discount on the issuance of convertible notes.

Other income (expense), net

Other income (expense), net consists primarily of interest income relating to our investment in money market funds as well as gains and losses related to foreign exchange transactions.

Sales and marketing expenses increased by $184,126 or 71.2%, to $442,658 for the nine months ended September 30, 2021, from $258,532 for the nine months ended September 30, 2020. The increase resulted primarily from increases in stock-based compensation expense due to expanded headcount, particularly at the senior levels, and an increased focus on business development, marketing, and public relations related spending.

Research and Development

Research and development expenses increased by $45,834 or 0.9%, to $4,920,320 for the nine months ended September 30, 2021, from $4,874,486 for the nine months ended September 30, 2020. The increase resulted primarily from hiring of external consultant for product development compared to one-time study related to seismic research of the EV1 system conducted during 2020 to test product stability in different terrains.

General and Administrative

General and administrative expenses increased by $4,185,608, or 94.4%, to $8,620,769 for the nine months ended September 30, 2021 from $4,435,161 for the nine months ended September 30, 2020. The increase resulted primarily from an increase in depreciation on property and equipment, an increase in payroll and related costs due to the increase in Energy Vault’s headcount. Further, the increase is attributable to external costs such as accounting, finance, tax compliance, auditing, legal, and other professional costs associated with preparing to become a public reporting entity.

Inventory write-down

Inventory write-down was $2,733,194 for the nine months ended September 30, 2021 as compared to $0 for the nine months ended September 30, 2020. The increase was due to the write down of components of the CDU that were damaged. This write-off and other related costs have been partially offset by an

insurance claim received by Energy Vault against the claim filed for damaged components. Additionally, other components, which were not previously installed, remain in inventory at their estimated net realizable value, as Energy Vault intends to sell them.

Other income, net

Change in fair value of derivative

Loss on revaluation of fair value adjustments decreased by $5,217,104 to $0 for the nine months ended September 30, 2021 from $5,217,104 for the nine months ended September 30, 2020. The derivative liability expired in June 2021 without exercise, resulting in the fair value of the derivative liability becoming $0 for the nine months ended September 30, 2021.

Interest expense

Interest expense net decreased by $9,246 to $6,799 for the nine months ended September 30, 2021 from $16,045 for the nine months ended September 30, 2020. The higher interest expense in 2020 was primarily due to interest expense on Series B-1 convertible notes. These notes got converted to Series B-1 preferred stock in December 2020. This decrease is partially offset by increase in finance lease obligations.

Other income (expense), net

Other expense was $1,865,542 for the nine months ended September 30, 2021 compared to other income of $1,173,497 for the nine months ended September 30, 2020. The change resulted primarily from fluctuations in foreign currency transaction gain and losses.

Comparison of the year ended December 31, 2020 to year ended December 31, 2019

The following table sets forth a summary of our consolidated results of operations for the years ended December 31, 2020 and December 30, 2019 and the changes between periods.

Operating expenses

Sales and Marketing

Sales and marketing expenses decreased by $621,770, or 66.6%, to $311,135 for the year ended December 31, 2020 from $932,905 for the year ended December 31, 2019. The decrease was primarily from the impact of the COVID-19 pandemic in early 2020, resulting in reduction of travel related costs, lower number of trade shows and reduced spending on materials and sales consultant costs as a result of the lower level of business development activities.

190

TABLE OF CONTENTS

Research and Development

Research and development expenses increased by $6,454,951, or 312.7%, to $8,519,541 for the year ended December 31, 2020 from $2,064,590 for the year ended December 31, 2019. The increase resulted primarily from an increase in material purchase costs and professional services fees as well as costs incurred for a one-time study related to seismic research of the EV1 to test product stability in different terrains. In 2019, the activities were limited to design of the CDU and in 2020, the product entered the development and construction phase involving higher construction-related costs.

General and Administrative

General and administrative expenses decreased by $1,340,407, or 19.1%, to $5,674,756 for the year ended December 31, 2020 from $7,015,163 for the year ended December 31, 2019. The decrease resulted primarily from lower legal and professional fees and an online theft incident in 2019, a majority of which was recovered through an insurance claim in 2020, partially offset by an increase in payroll and related costs due to increased headcount to support the growth in our operations.

Other income (expense)

Change in fair value of derivative

Loss on revaluation of the derivative instrument was $11,923,000 for the year ended December 31, 2020 compared to a gain of $776,407 for the year ended December 31, 2019. The change resulted from loss on the fair value of the derivative instrument related to Series-B preferred stock.

Interest Expense

Interest expense, net decreased by $1,063,234, or 89.2%, to $128,134 for the year ended December 31, 2020 from $1,191,368 for the year ended December 31, 2019. The decrease resulted primarily from lower discount on the issuance of the Series B-1 convertible notes during 2020 as compared to the higher discount on issuance of the Series A-1 convertible notes during 2019.

Other Income, net

Other income increased by $2,099,413, or 731.5%, to $2,386,395 for the year ended December 31, 2020 from $286,982 for the year ended December 31, 2019. The increase resulted primarily from the increase in foreign currency transaction gains.

Liquidity and Capital Resources

Since inception, we have financed our operations primarily through the issuance and sale of equity, debt, convertible notes and preferred stock. We have not generated any cash from our operations.

During August and September 2021, we entered into financing arrangements with a large institutional investor and existing stockholders consisting of the sale of 2,182,515 shares of our Series C Preferred Stock at a price of $49.0258 per share for net proceeds of approximately $ 105.4 million. To augment our liquidity position further, we entered into the Business Combination Agreement with Novus on September 8, 2021. The transaction is expected to close in early 2022. On September 8, 2021, Novus announced that it received Subscription Agreements for the purchase of approximately $100 million of additional capital from the sale of Novus Common Stock in the PIPE, which is expected to close concurrently with the Business Combination.

Our consolidated financial statements do not reflect the transactions contemplated by the above-mentioned Business Combination. However, even assuming maximum redemptions of approximately $218.4 million by Novus stockholders pursuant to the Business Combination, management believes the pro forma cash and cash equivalents of approximately $238.0 million will be adequate to fund operations, manufacturing, research and development, administration as well as sales and marketing costs for at least the next twelve months. Should we enter into definitive collaboration and/or joint venture agreements or engage in business combinations in the future, we may be required to seek additional financing.

TABLE OF CONTENTS

We may continue to incur additional losses for the next several years, and we may seek additional capital through equity and/or debt financings depending on market conditions. If we are required to raise additional funds by issuing equity securities, dilution to stockholders would result. Any equity securities issued may also provide for rights, preferences or privileges senior to those of holders of our common stock. If we raise funds by issuing debt securities, these debt securities would have rights, preferences and privileges senior to those of holders of common stock. The terms of debt securities or borrowings could impose significant restrictions on our operations. The credit market and financial services industry have in the past, and may in the future, experience periods of uncertainty that could impact the availability and cost of equity and debt financing.

In March 2020, we received $518,645 in aggregate loan proceeds under the Swiss Government COVID-19 Financial Assistance Program. The note does not bear interest and matures in 60 months from the date of issuance. The note was repaid in full on September 8, 2021.

In May 2020, we received $220,020 in aggregate loan proceeds pursuant to the Paycheck Protection Program established under the CARES Act (the Coronavirus Aid, Relief, and Economic Security Act) of 2020. The loan accrued interest at the rate of 1% per annum. The loan was repaid in full on September 3, 2021.

As of September 30, 2021, we had $116,290,730 of cash and cash equivalents. As reflected in our consolidated financial statements included elsewhere in this proxy statement/prospectus, we had an accumulated deficit as of September 30, 2021, and a net loss and net cash used in operating activities for the reporting period then ended. Energy Vault expects to incur losses in the foreseeable future due to its on-going research and development activities and may require additional sources of capital. Management believes that with the current cash position and business combination, including the proceeds from the PIPE, the Combined Company will have sufficient cash to continue to execute its business plan for at least the next twelve months.

TABLE OF CONTENTS

Critical Accounting Policies and Use of Estimates

Our financial statements are prepared in conformity with GAAP. In preparing our financial statements, we make assumptions, judgments, and estimates based on historical experience and various other factors that we believe to be reasonable under the circumstances. Actual results could differ materially from these estimates under different assumptions and conditions.

Our significant accounting policies are described in Note 1 to the audited consolidated financial statements of Energy Vault included elsewhere in this proxy statement/prospectus, and we believe that the accounting policies discussed below are critical to understanding its historical and future performance as these policies involve a greater degree of judgment and complexity.

Stock-Based Compensation

Accounting for stock-based compensation requires us to make a number of judgments, estimates and assumptions. If any of the estimates prove to be inaccurate, Energy Vault’s net loss and operating results could be affected adversely.

The stock-based compensation arrangements are accounted for in accordance with ASC Topic 718, “Share Based Payments”. Compensation expense is recognized over the requisite service period (usually the vesting period) on a straight-line basis and adjusted for actual forfeitures of unvested awards as they occur.

Stock awards that vest solely based on a service condition are measured based on the estimated fair values of the awards as of the grant date using the Black-Scholes option-pricing model, which is impacted by the following assumptions:

•

Expected Term — The expected term represents the period that Energy Vault’s awards granted are expected to be outstanding and is determined based upon the simplified method, as we do not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior.

•

Expected Volatility — Since we are privately held and do not have any trading history for our common stock, the expected volatility was estimated based on the average volatility for comparable publicly traded companies over a period equal to the expected term of the stock award grants.

•

Risk-Free Interest Rate — We use the U.S. Treasury yield for our risk-free interest rate that corresponds with the expected term.

•

Expected Dividend — Energy Vault has never paid dividends on its common stock and has no plans to pay dividends in the foreseeable future. Therefore, an expected dividend yield of zero was used.

The grant date fair value of our Common Stock was determined using valuation methodologies which utilize certain assumptions, including probability weighting of events, volatility, time to liquidation, a risk-free interest rate, and an assumption for a discount for lack of marketability (Level 3 inputs).

Defined Benefit Pension Obligation

Energy Vault’s wholly owned subsidiary in Switzerland has a defined benefit pension obligation covering retirement and other long-term benefits for the local employees. The plan is a statutory requirement in accordance with local regulations which is accounted for and disclosed in accordance with the provisions of GAAP relating to the accounting for pension plans. These GAAP provisions require the use of assumptions, such as the discount rate for liabilities and long-term rate of return on assets, in determining the projected benefit obligation, fair value of plan assets and an underfunded net benefit obligation.

Emerging Growth Company Accounting Election

We are an “emerging growth company” as defined in Section 2(a) of the Securities Act of 1933, as amended, and have irrevocably elected to take advantage of the benefits of this extended transition period for new or revised standard. We are expected to remain an emerging growth company at least through the end of the 2021 fiscal year and is expected to continue to take advantage of the benefits of the extended

194

TABLE OF CONTENTS

transition period. This may make it difficult or impossible to compare our financial results with the financial results of another public company that is either not an emerging growth company or is an emerging growth company that has chosen not to take advantage of the extended transition period exemptions for emerging growth companies because of the potential differences in accounting standards used.

Recently Adopted and Issued Accounting Pronouncements

Recently issued and adopted/unadopted accounting pronouncements are described in Note 2 to the consolidated financial statements of Energy Vault included elsewhere in this proxy statement/prospectus.

Quantitative and Qualitative Disclosures About Market Risk

Market risk represents the risk of loss that may impact our financial position because of adverse changes in financial market prices and rates.

Foreign Currency Risk

Our market risk exposure is primarily a result of exposure resulting from potential changes in foreign currency exchange related to the intercompany loan with our subsidiary that are denominated in currency other than the U.S. dollar. We have not engaged in the hedging of foreign currency transactions to date, although we may choose to do so in the future. A 10% increase or decrease in the value of the Swiss franc to the U.S. dollar would have caused our reported annual net loss to increase or decrease by approximately $2.9 million for the year ended December 31, 2020.

Inflation Risk

Our operations could be adversely impacted by inflation, primarily from higher material, labor, and construction costs. While it is difficult to measure the impact of inflation for such estimates accurately, we believe, if our costs are affected due to significant inflationary pressures, we may not be able to fully offset higher costs through price increases or other corrective measures, which may adversely affect our business, financial condition and results of operations.

Consulting Agreement

On October 25, 2019, Energy Vault SA, the wholly owned subsidiary of Energy Vault, Inc., entered into a consulting agreement with Mauro Pedretti, father of Andrea Pedretti. Under the terms of the agreement, Mr. Pedretti’s duties include consulting engineering services and assistance as requested by our Chief Executive Officer and other members of our management team. The term of the agreement commenced in 2019 and continues to be effective.

Commercial Agreements

In 2018, Energy Vault entered into a Services Agreement with Idealab, a California corporation, pursuant to which Energy Vault purchased services relating to, among other things, the use of facilities, human resources, legal services and accounting, totaling $134,267, $203,133 and $56,475 for the years ended December 31, 2020, 2019 and 2018, respectively.

Such sale of Energy Vault Common Stock was also evidenced by a stock purchase agreement dated March 5, 2018.

Bill Gross is a director of Energy Vault and an affiliate of Idealab.

Other Agreements with Principal Stockholders

In April 2019, Energy Vault incurred a loss of approximately $1.5 million from a phishing scheme that targeted Idealab and Energy Vault.

In November 2020, Energy Vault and Idealab reached an agreement to settle all claims relating to this incident. Pursuant to such settlement agreement, Idealab agreed to pay Energy Vault $900,000, and each of the parties agreed to generally release the other party of all claims relating to this incident.

Stockholder Support Agreement

Policies and Procedures for Related Party Transactions

The Energy Vault Board reviews and considers the interests of its directors, executive officers and principal stockholders in its review and consideration of transactions and forms committees of non-interested directors when it determines that the formation of such committees is appropriate under the circumstances.

All of the transactions described in this section will have been entered into prior to the expected adoption of this policy. Although Energy Vault has not had a written policy for the review and approval of transactions with related persons, the Energy Vault Board, which has included Mr. Piconi and at times affiliates of Idealab, Neotribe, Helena, SoftBank Vision Fund and Prime Movers Lab, has historically reviewed and approved any transaction where a director or officer had a financial interest, including the transactions described above. Prior to approving such a transaction, the material facts as to a director’s or executive officer’s relationship or interest in the agreement or transaction were disclosed to the Energy Vault Board. The Energy Vault Board took this information into account when evaluating the transaction and in determining whether such transaction was fair to Energy Vault and in the best interest of all Energy Vault Stockholders.

The Combined Company intends to adopt a new written related party transaction policy to be effective upon the completion of the Business Combination. The policy will provide that officers, directors, holders of more than 5% of any class of the Combined Company’s voting securities, and any member of the immediate family of and any entity affiliated with any of the foregoing persons, will not be permitted to enter into a

related-party transaction with the Combined Company without the prior consent of the audit committee, or other independent members of the New Energy Vault Board in the event it is inappropriate for the audit committee to review such transaction due to a conflict of interest. Any request for the Combined Company to enter into a transaction with an executive officer, director, principal stockholder, or any of their immediate family members or affiliates, in which the amount involved exceeds $120,000, must first be presented to the audit committee for review, consideration and approval. In approving or rejecting the proposed transactions, the audit committee will take into account all of the relevant facts and circumstances available.

INFORMATION ABOUT NOVUS

As used in this section, unless the context suggests otherwise, “we,” “us,” “our,” or “Novus” refer to Novus Capital Corporation II.

Overview

We are a Delaware blank check company incorporated on September 29, 2020 formed for the purpose of entering into a merger, capital stock exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination with one or more target businesses. We were formed to capitalize on the significant experience and contacts of our management team to complete our initial business combination.

The registration statement on Form S-1 (File No. 333-252079) for our IPO was declared effective by the SEC on February 2, 2021. On February 8, 2021, we consummated our IPO of 28,750,000 Novus Units, with each Novus Unit consisting of one-third of one share of Novus Common Stock and one-third of one redeemable Novus Warrant. Each Novus Warrant entitles the holder to purchase one share of Novus Common Stock, $0.0001 par value per share, at $11.50 per share. The Novus Warrants will expire at 5:00 p.m., New York City time, five years after the completion of Novus’s initial business combination, or earlier upon redemption or liquidation. The Novus Units in our IPO were sold at an offering price of $10.00 per unit, generating total gross proceeds of $100.0 million.

Simultaneously with the consummation of our IPO, we consummated a private placement in which the Founders purchased an aggregate of 7,187,500 shares of Novus Class B common stock, generating total gross proceeds of approximately $25,000. In addition, the Founders and/or their designees purchased from us an aggregate of 5,166,666 Private Warrants (4,816,666 Private Warrants by the Novus Initial Stockholders and/or their designees and 350,000 Private Warrants by NCCII) at a price of $1.50 per warrant, for an aggregate purchase price of $7.75 million in a private placement that occurred simultaneously with the closing of our IPO.

In connection with the IPO, we incurred transaction costs of $6,224,714, consisting of $5.75 million of underwriting fees and $474,714 of other costs. A total of $287.5 million from the net proceeds of the sale of the Novus Units in the IPO and the private placement were placed in the Trust Account, with Continental Stock Transfer & Trust Company acting as trustee.

Initial Business Combination

Our initial business combination must occur with one or more target businesses that together have an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the income earned on the Trust Account) at the time of the agreement to enter into the initial business combination. If our board of directors is not able to independently determine the fair market value of the target business or businesses, we will obtain an opinion from an independent investment banking firm that is a member of the Financial Industry Regulatory Authority, Inc. with respect to the satisfaction of such criteria.

Submission of Our Initial Business Combination to a Stockholder Vote

We are providing the Public Stockholders with redemption rights upon consummation of the Business Combination. Public stockholder electing to exercise their redemption rights will be entitled to receive cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination, including any amounts representing interest earned on the Trust Account, less taxes payable, provided that such stockholders follow the specific procedures for redemption set forth in this proxy statement/prospectus relating to the stockholder vote on the Business Combination. The Public Stockholders are not required to vote against the Business Combination in order to exercise their redemption rights. If the Business Combination is not completed, then Public Stockholders electing to exercise their redemption rights will not be entitled to receive such payments.

The Founders and our executive officers and directors have agreed (1) to vote any shares of common stock owned by them in favor of the Business Combination, including the Founder Shares and the shares of

204

TABLE OF CONTENTS

Novus Common Stock underlying the Private Warrants, (2) not to redeem any shares of Novus Common Stock or Founder Shares in connection with a stockholder vote to approve the Business Combination, and (3) not sell any shares of Novus Common Stock or Founder Shares in any tender in connection with the Business Combination. As a result, we would need only 10,781,251, or approximately 37.5%, of the 28,750,000 Public Shares sold in the IPO to be voted in favor of a transaction in order to proceed with the Business Combination.

If you or a “group” of stockholders of which you are a part are deemed to hold an aggregate of more than 15% of the shares of Novus Common Stock, you (or, ,if a member of such a group, all of the members of such group in the aggregate) will lose the ability to redeem all such shares in excess of 15% of the Novus Common Stock.

Permitted Purchases of Our Securities

Although certain of our officers and directors and their affiliates have agreed to purchase an aggregate of 1,100,000 shares of Novus Common Stock in the PIPE, none of our Founders, executive officers, directors, director nominees or their affiliates have indicated any intention to purchase units or shares of Novus Common Stock from persons in the open market or in private transactions. However, in connection with the stockholder vote to approve the proposed Business Combination, the Founders and Novus’s board of directors, officers, advisors or their affiliates may privately negotiate transactions to purchase shares prior to the Closing from stockholders who would have otherwise elected to have their shares redeemed in conjunction with a proxy solicitation pursuant to the proxy rules for a per share pro rata portion of the Trust Account without the prior written consent of Energy Vault. None of the Founders, directors, officers or advisors, or their respective affiliates, will make any such purchases when they are in possession of any material non-public information not disclosed to the seller of such shares. Such a purchase would include a contractual acknowledgement that such stockholder, although still the record holder of such shares, is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights. In the event that the Founders, directors, officers or advisors, or their affiliates, purchase shares in privately negotiated transactions from Public Stockholders who have already elected to exercise their redemption rights, such selling stockholders would be required to revoke their prior elections to redeem their shares. Any such privately negotiated purchases may be effected at purchase prices that are in excess of the per share pro rata portion of the Trust Account. The purpose of these purchases would be to increase the amount of cash available to Novus for use in the Business Combination. However, such persons have no current commitments, plans or intentions to engage in such transactions and have not formulated any terms or conditions for any such transactions.

We cannot currently determine whether any of our insiders will make such purchases pursuant to a Rule 10b5-1 plan, as that would be dependent upon several factors, including but not limited to the timing and size of any such purchase. Depending on the circumstances, any of our insiders may decide to make purchases of our securities pursuant to a Rule 10b5-1 plan or may determine that acting pursuant to such a plan is not required under the Exchange Act.

Our Founders, executive officers, directors, director nominees and their affiliates anticipate that they may identify the stockholders with whom they may pursue privately negotiated purchases by either the stockholders contacting us directly or by our receipt of redemption requests submitted by stockholders following our mailing of proxy materials in connection with the Business Combination. To the extent that our Founders, executive officers, directors, director nominees or their affiliates enter into a private purchase, they would identify and contact only potential selling stockholders who have expressed their election to redeem their shares for a pro rata share of the Trust Account or vote against the Business Combination.

We do not currently anticipate that purchases of our Public Shares or Public Warrants by any of our Founders, directors, director nominees, executive officers, advisors or any of their affiliates, if any, would constitute a tender offer subject to the tender offer rules under the Exchange Act or a going-private transaction subject to the going-private rules under the Exchange Act; however, if the purchasers determine at the time of any such purchases that the purchases are subject to such rules, the purchasers will comply with such rules. Any such purchases will be reported pursuant to Section 13 and Section 16 of the Exchange Act to the extent such purchasers are subject to such reporting requirements. None of our Founders, directors, director

205

TABLE OF CONTENTS

nominees, officers, advisors or any of their affiliates will purchase shares of Novus Common Stock if such purchases would violate Section 9(a)(2) or Rule 10b-5 of the Exchange Act.

Redemption Rights for Public Stockholders

We will provide the Public Stockholders with the opportunity to redeem all or a portion of their shares of Novus Common Stock upon the completion of the Business Combination at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination, including any interests earned on the funds held in the Trust Account less any taxes then due but not yet paid (which taxes may be paid only from the interest earned on the funds in the Trust Account). As of [ ], 2021, the amount in the Trust Account was approximately $287.5 million, which is equal to approximately $[*] per Public Share. Our Founders have entered into a letter agreement with us, pursuant to which they agreed for no additional consideration to waive their redemption rights with respect to any Founder Shares and any Public Shares held by them in connection with the completion of the Business Combination.

Redemption of Public Shares and Liquidation if No Initial Business Combination

The Existing Certificate of Incorporation provides that we will have until February 8, 2023 to complete an initial business combination. If we have not completed an initial business combination by such date or obtained the approval of Novus’s stockholders to extend the deadline for us to consummate an initial business combination, we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem 100% of the outstanding Public Shares, at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest not previously released to us to pay taxes and any other taxes payable, divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our board of directors, dissolve and liquidate, subject (in the case of (ii) and (iii) above) to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the Novus Warrants, which will expire worthless if we fail to complete our initial business combination within the 18-month time period.

Our Founders, officers and directors have entered into a letter agreement with us, pursuant to which they have waived their rights to liquidating distributions from the trust account with respect to any Founder Shares and held by them if we fail to complete our initial business combination within the prescribed time period. However, if our Founders or any of our officers, directors or any of their respective affiliates then hold any Public Shares, they will be entitled to liquidating distributions from the trust account with respect to such Public Shares if we fail to complete our initial business combination within the allotted time frame to complete our initial business combination.

Our Founders, officers and directors have agreed, pursuant to a written agreement with us, that they will not propose any amendment to our amended and restated certificate of incorporation (A) to modify the substance or timing of our obligation to allow redemptions in connection with our initial business combination or to redeem 100% of our Public Shares if we have not consummated our initial business combination within 24 months from the closing of this offering or (B) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity, unless we provide our Public Stockholders with the opportunity to redeem their shares of Novus Common Stock upon approval of any such amendment at a per- share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest (which interest shall be net of taxes payable), divided by the number of then outstanding Public Shares. However, we may not redeem our Public Shares in an amount that would cause our net tangible assets to be less than $5,000,001 following such redemptions.

206

TABLE OF CONTENTS

We expect that all costs and expenses associated with implementing our plan of dissolution, as well as payments to any creditors, will be funded from amounts remaining out of the estimated $1,000,000 of proceeds held outside the trust account, although we cannot assure you that there will be sufficient funds for such purpose. However, if those funds are not sufficient to cover the costs and expenses associated with implementing our plan of dissolution, to the extent that there is any interest accrued in the trust account not required to pay taxes, we may request the trustee to release to us an additional amount of up to $100,000 of such accrued interest to pay those costs and expenses.

We are required to use our reasonable best efforts to have all third parties (including any vendors or other entities we engage after the IPO) and any prospective target businesses enter into agreements with us waiving any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account. As a result, the claims that could be made against us will be limited, thereby lessening the likelihood that any claim would result in any liability extending to the trust. We therefore believe that any necessary provision for creditors will be reduced and should not have a significant impact on our ability to distribute the funds in the Trust Account to the Public Stockholders. Nevertheless, we cannot assure you of this fact as there is no guarantee that vendors, service providers and prospective target businesses will execute such agreements. If any third party refuses to execute an agreement waiving such claims to the monies held in the Trust Account, our management will perform an analysis of the alternatives available to it and will only enter into an agreement with a third party that has not executed a waiver if management believes that such third party’s engagement would be significantly more beneficial to us than any alternative. Examples of possible instances where we may engage a third party that refuses to execute a waiver include the engagement of a third-party consultant whose particular expertise or skills are believed by management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where management is unable to find a service provider willing to execute a waiver. Our underwriters and auditor are the only third parties we are currently aware of that may not execute a waiver. Nor is there any guarantee that, even if they execute such agreements with us, they will not seek recourse against the Trust Account.

V Donargo LLC, an entity controlled by Vincent Donargo, our Chief Financial Officer, has agreed that it will be liable to us if and to the extent any claims by a third party for services rendered or products sold to us, or a prospective target business with which we have discussed entering into a transaction agreement, reduce the amount of funds in the trust account to below (1) $10.00 per Public Share; or (2) such lesser amount per Public Share held in the trust account as of the date of the liquidation of the Trust Account due to reductions in the value of the Trust assets, in each case net of the amount of interest which may be withdrawn to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under our indemnity of the underwriters of the IPO against certain liabilities, including liabilities under the Securities Act. Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, V Donargo LLC will not be responsible to the extent of any liability for such third-party claims. We have not independently verified whether V Donargo LLC has sufficient funds to satisfy its indemnity obligations and believe that its only assets are stock of our company. Therefore, V Donargo LLC may not be able to satisfy those obligations. We have not asked V Donargo LLC to reserve for such obligations. Therefore, we cannot assure you that it would be able to satisfy those obligations. As a result, if any such claims were successfully made against the trust account, the funds available for our initial business combination and redemptions could be reduced to less than $10.00 per Public Share. In such event, we may not be able to complete our initial business combination, and you would receive such lesser amount per share in connection with any redemption of your Public Shares. None of our officers or directors will indemnify us for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

In the event that the proceeds in the Trust Account are reduced below: (1) $10.00 per Public Share or (2) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, due to reductions in the value of the trust assets, in each case net of the amount of interest which may be withdrawn to pay our franchise and income taxes, and V Donargo LLC asserts that it is unable to satisfy its indemnification obligations or that it has no indemnification obligations related to a particular claim, our independent directors would determine whether to take legal action against V Donargo LLC to enforce its indemnification obligations. While we currently expect that our independent directors would take legal action on our behalf against V Donargo LLC to enforce its indemnification obligations to us, it is possible that our independent directors in exercising their business judgment and subject to their fiduciary

duties may choose not to do so in certain instances. Accordingly, we cannot assure you that due to claims of creditors the actual value of the per share redemption price will not be substantially less than $10.00 per share.

Under the DGCL, stockholders may be held liable for claims by third parties against a corporation to the extent of distributions received by them in a dissolution. The pro rata portion of our Trust Account distributed to the Public Stockholders upon the redemption of 100% of our outstanding Public Shares in the event we do not complete our initial business combination within the required time period may be considered a liquidation distribution under Delaware law. If the corporation complies with certain procedures set forth in Section 280 of the DGCL intended to ensure that it makes reasonable provision for all claims against it, including a 60-day notice period during which any third-party claims can be brought against the corporation, a 90-day period during which the corporation may reject any claims brought, and an additional 150-day waiting period before any liquidating distributions are made to stockholders, any liability of stockholders with respect to a liquidating distribution is limited to the lesser of such stockholder’s pro rata share of the claim or the amount distributed to the stockholder, and any liability of the stockholder would be barred after the third anniversary of the dissolution.

Furthermore, if the pro rata portion of our Trust Account distributed to the Public Stockholders upon the redemption of 100% of our Public Shares in the event we do not complete our initial business combination within the required time period is not considered a liquidation distribution under Delaware law and such redemption distribution is deemed to be unlawful, then pursuant to Section 174 of the DGCL, the statute of limitations for claims of creditors could then be six years after the unlawful redemption distribution, instead of three years, as in the case of a liquidation distribution. If we are unable to complete an initial business combination within the prescribed time frame, we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem 100% of the outstanding Public Shares, at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest, divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our board of directors, dissolve and liquidate, subject (in the case of (ii) and (iii) above) to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Accordingly, it is our intention to redeem our Public Shares as soon as reasonably possible following the 18-month anniversary of the closing of the IPO, and, therefore, we do not intend to comply with those procedures. As such, our stockholders could potentially be liable for any claims to the extent of distributions received by them (but no more) and any liability of our stockholders may extend well beyond the third anniversary of such date.

Because we will not be complying with Section 280 of the DGCL, Section 281(b) of the DGCL requires us to adopt a plan, based on facts known to us at such time that will provide for our payment of all existing and pending claims or claims that may be potentially brought against us within the subsequent ten years. However, because we are a blank check company, rather than an operating company, and our operations will be limited to searching for prospective target businesses to acquire, the only likely claims to arise would be from our vendors (such as lawyers, investment bankers, etc.) or prospective target businesses.

If we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, the proceeds held in the trust account could be subject to applicable bankruptcy law, and may be included in our bankruptcy estate and subject to the claims of third parties with priority over the claims of our stockholders. To the extent any bankruptcy claims deplete the trust account, we cannot assure you we will be able to return $10.00 per share to our Public Stockholders. Additionally, if we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, any distributions received by stockholders could be viewed under applicable debtor/creditor and/or bankruptcy laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy court could seek to recover some or all amounts received by our stockholders. Furthermore, our board of directors may be viewed as having breached its fiduciary duty to our creditors and/or may have acted in bad faith, and thereby exposing itself and our company to claims of punitive damages, by paying public stockholders from the trust account prior to addressing the claims of creditors. We cannot assure you that claims will not be brought against us for these reasons.

TABLE OF CONTENTS

A Public Stockholder will be entitled to receive funds from the trust account only upon the earliest to occur of: (1) the completion of our initial business combination and then, only in connection with those Public Shares that such stockholder has properly elected to redeem, subject to the limitations described in this prospectus; (2) the redemption of any Public Shares properly submitted in connection with a stockholder vote to amend our amended and restated certificate of incorporation (A) to modify the substance or timing of our obligation to allow redemptions in connection with our initial business combination or to redeem 100% of our Public Shares if we do not complete our initial business combination by February 8, 2023 or (B) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity; and (3) the redemption of all of our Public Shares if we have not completed our initial business combination within 24 months from the closing of our IPO, or February 8, 2023, subject to applicable law. In no other circumstances will a Public Stockholder have any right or interest of any kind to or in the trust account. In the event we seek stockholder approval in connection with our initial business combination, a stockholder’s voting in connection with our initial business combination alone will not result in a stockholder’s redeeming its shares to us for an applicable pro rata share of the trust account. Such stockholder must have also exercised its redemption rights described above. Holders of Novus Warrants will not have any rights of proceeds held in the Trust Account with respect to the Novus Warrants.

Facilities

We currently maintain our principal executive offices at 8556 Oakmont Lane, Indianapolis, IN 46260 which is provided to us by Robert J. Laikin, our Chief Executive Officer, for no fee. We consider our current office space, combined with the other office space otherwise available to our executive officers, adequate for our current operations.

Employees

We have two executive officers. These individuals are not obligated to devote any specific number of hours to our matters and intend to devote only as much time as they deem necessary to our affairs. The amount of time they will devote in any time period will vary based on whether a target business has been selected for the business combination and the stage of the business combination process the company is in. Accordingly, once a suitable target business to acquire has been located, management may spend more time investigating such target business and negotiating and processing the business combination (and consequently spend more time on our affairs) than had been spent prior to locating a suitable target business. We presently expect our executive officers to devote such amount of time as they reasonably believe is necessary to our business. We do not intend to have any full-time employees prior to the consummation of an initial business combination.

Our directors and executive officers as of the Record Date are listed below:

Mr. Foster holds a B.A.A.S. from Texas State University. We believe Mr. Foster is well qualified to serve on our board of directors because experience in mergers and acquisitions, investments experience and the healthcare, technology and logistics industries, and his knowledge of the public markets broadens the scope of our board of directors’ oversight of our financial performance.

Heather Goodman has served as a member of our board of directors since our inception.

Mr. Sznaider is also currently a member of the American Meteorological Society Commission on Weather, Water, and Climate Enterprise. Mr. Sznaider holds a BS from the University of Wisconsin-Madison. We believe Mr. Sznaider is well suited to serve as a Board member because he has significant operational experience in multiple technology business disciplines, considerable M&A experience, and private-public-partnership experience relating to environmental and sustainability topics including active initiatives with the United Nations.

Number, Terms of Office and Election of Executive Officers and Directors

Our board of directors is divided into three classes, with only one class of directors being elected in each year, and with each class (except for those directors appointed prior to our first annual meeting of stockholders) serving a three-year term. The term of office of the first class of directors, consisting of Ms. Goodman and Mr. Sznaider, will expire at our first annual meeting of stockholders. The term of office of the second class of directors, consisting of Messrs. Paulson and Klaff, will expire at our second annual meeting of stockholders. The term of office of the third class of directors, consisting of Messrs. Laikin and Foster, will expire at our third annual meeting of stockholders.

211

TABLE OF CONTENTS

Our officers are appointed by the board of directors and serve at the discretion of the board of directors, rather than for specific terms of office. Our board of directors is authorized to appoint persons to the offices set forth in our bylaws as it deems appropriate. Our bylaws will provide that our officers may consist of a Chairman of the Board, a Chief Executive Officer, a Chief Financial Officer, a Secretary and such other officers (including without limitation, a President, Vice Presidents, Assistant Secretaries, and a Treasurer) as our board of directors from time to time may determine.

Executive Officer and Director Compensation

No executive officer has received any cash compensation for services rendered to us.

None of our officers or directors have received any compensation for services rendered to us. Our founders, officers, directors and their respective affiliates will be reimbursed for any out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. Our audit committee will review on a quarterly basis all payments that were made by us to our sponsors, officers, directors or our or any of their respective affiliates.

After the completion of our initial business combination, directors or members of our management team who remain with us may be paid consulting, management or other compensation from the combined company. All compensation will be fully disclosed to stockholders, to the extent then known, in the tender offer materials or proxy solicitation materials furnished to our stockholders in connection with a proposed business combination. It is unlikely the amount of such compensation will be known at the time such materials are distributed, because the directors of the post-combination business will be responsible for determining executive officer and director compensation. Any compensation to be paid to our officers after the completion of our initial business combination will be determined by a compensation committee constituted solely by independent directors.

We are not party to any agreements with our officers and directors that provide for benefits upon termination of employment. The existence or terms of any such employment or consulting arrangements may influence our management’s motivation in identifying or selecting a target business, and we do not believe that the ability of our management to remain with us after the consummation of our initial business combination should be a determining factor in our decision to proceed with any potential business combination.

Committees of the Board of Directors

Our board of directors has three standing committees: an audit committee, a compensation committee and a nominating and corporate governance committee, each of which will be composed solely of independent directors. Subject to phase-in rules, the rules of the NYSE and Rule 10A-3 of the Exchange Act require that the audit committee of a listed company be comprised solely of independent directors, and the rules of the NYSE require that the compensation committee and the nominating and corporate governance committee of a listed company be comprised solely of independent directors. Each committee will operate under a charter that will be approved by our board of directors and will have the composition and responsibilities described below. The charter of each committee is available on our website.

Audit Committee

The members of our audit committee are Heather Goodman, Larry M. Paulson and Ronald J. Sznaider. Ms. Goodman serves as chairwoman of the audit committee.

Each member of the audit committee is financially literate and our board of directors has determined that Heather Goodman qualifies as an “audit committee financial expert” as defined in applicable SEC rules and has accounting or related financial management expertise.

Our audit committee charter details the purpose and principal functions of the audit committee, including:

212

TABLE OF CONTENTS

•

Compensation Committee

The members of our compensation committee are Larry M. Paulson, Heather Goodman and Hersch Klaff. Mr. Paulson serves as chairman of the compensation committee.

Our compensation committee charter details the purpose and responsibilities of the compensation committee, including:

•

reviewing and approving on an annual basis the corporate goals and objectives relevant to our Chief Executive Officer’s compensation, evaluating our Chief Executive Officer’s performance in light of such goals and objectives and determining and approving the remuneration (if any) of our Chief Executive Officer based on such evaluation;

•

213

TABLE OF CONTENTS

•

•

reviewing, evaluating and recommending changes, if appropriate, to the remuneration for directors.

The charter also provides that the compensation committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, independent legal counsel or other adviser and will be directly responsible for the appointment, compensation and oversight of the work of any such adviser. However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the compensation committee will consider the independence of each such adviser, including the factors required by the NYSE and the SEC.

Nominating Committee

The members of our nominating and corporate governance committee are Hersch Klaff, Jeffrey Foster and Ronald J. Sznaider. Mr. Klaff serves as chair of the nominating and corporate governance committee.

Our nominating and corporate governance committee charter details the purpose and responsibilities of the nominating and corporate governance committee, including:

•

identifying, screening and reviewing individuals qualified to serve as directors, consistent with criteria approved by the board, and recommending to the board director candidates for nomination for election at the annual meeting of stockholders or to fill vacancies on the board of directors;

•

developing and recommending to the board of directors and overseeing implementation of our corporate governance guidelines;

•

coordinating and overseeing the annual self-evaluation of the board of directors, its committees, individual directors and management in the governance of the company; and

•

reviewing on a regular basis our overall corporate governance and recommending improvements as and when necessary.

The charter also provides that the nominating and corporate governance committee may, in its sole discretion, retain or obtain the advice of, and terminate, any search firm to be used to identify director candidates, and will be directly responsible for approving the search firm’s fees and other retention terms.

We have not formally established any specific, minimum qualifications that must be met or skills that are necessary for directors to possess. In general, in identifying and evaluating nominees for director, the board of directors considers educational background, diversity of professional experience, knowledge of our business, integrity, professional reputation, independence, wisdom, and the ability to represent the best interests of our stockholders. Prior to our initial business combination, holders of our Public Shares will not have the right to recommend director candidates for nomination to our board of directors.

Code of Ethics

We have adopted a code of ethics that applies to our officers and directors. We have filed copies of our code of ethics, our audit committee charter, nominating committee charter and compensation committee charter as exhibits to our registration statement in connection with our IPO. You may review these documents by accessing our public filings at the SEC’s web site at www.sec.gov. In addition, a copy of the code of ethics will be provided without charge upon request to us.

Audit Fees

The firm of Marcum LLP (“Marcum”) acts as our independent registered public accounting firm. The following is a summary of fees paid to Marcum for services rendered.

Audit Fees. Audit fees consist of fees for professional services rendered for the review of our quarterly financial statements and services that are normally provided by Marcum in connection with regulatory filings. The aggregate fees of Marcum for professional services rendered for the review of the financial information included in our Forms 10-Q for the respective periods and other required filings with the SEC for the period from September 29, 2020 (date of inception) to December 31, 2020 totaled approximately $25,750.

NOVUS MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The statements in the discussion and analysis regarding industry outlook, our expectations regarding the performance of our business and the forward-looking statements are subject to numerous risks and uncertainties, including, but not limited to, the risks and uncertainties described in “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements.” Our actual results may differ materially from those contained in or implied by any forward-looking statements. You should read the following discussion together with the sections titled “Risk Factors,” “Information About Novus” and the audited consolidated financial statements, including the related notes, appearing elsewhere in this proxy statement/prospectus. All references to years, unless otherwise noted, refer to our fiscal years, which ends on December 31. As used in this section, unless the context suggests otherwise, “we,” “us,” “our,” or “Novus” refer to Novus Capital Corporation II.

This Novus Management’s Discussion and Analysis of Financial Condition and Results of Operations has been amended and restated to give effect to the restatements of our condensed financial statements as of March 31, 2021 and June 30, 2021. Management identified errors made in its historical financial statements where, at the closing of our Initial Public Offering, we improperly valued our Class A common stock subject to possible redemption. We previously determined the Class A common stock subject to possible redemption to be equal to the redemption value of $10.00 per share of Class A common stock while also taking into consideration a redemption cannot result in net tangible assets being less than $5,000,001. Management determined that the Class A common stock issued during the Initial Public Offering can be redeemed or become redeemable subject to the occurrence of future events considered outside of the Company’s control. Therefore, Management concluded that the temporary equity should include all Class A common stock subject to possible redemption. As a result, Management has noted a classification error related to temporary equity and permanent equity. This resulted in a restatement to the initial carrying value of the Class A common stock subject to possible redemption with the offset recorded to additional paid-in capital (to the extent available), accumulated deficit and Class A common stock.

Overview

We are a blank check company formed under the laws of the State of Delaware on September 29, 2020, for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses. We intend to effectuate our business combination using cash from the proceeds of our IPO and the sale of the Private Warrants, our capital stock, debt or a combination of cash, stock and debt.

The issuance of additional shares of our stock in the Business Combination:

•

may significantly reduce the equity interest of our stockholders;

•

may subordinate the rights of holders of shares of common stock if we issue shares of preferred stock with rights senior to those afforded to our shares of common stock;

•

will likely cause a change in control if a substantial number of our shares of common stock are issued, which may affect, among other things, our ability to use our net operating loss carry forwards, if any, and most likely will also result in the resignation or removal of our present officers and directors; and

•

may adversely affect prevailing market prices for our securities.

As indicated in the accompanying financial statements, we had $882,585 in cash and investments held in the Trust Account of approximately $287.5 million at September 30, 2021. We expect to continue to incur significant costs in the pursuit of our acquisition plans. We cannot assure you that our plans to complete the Business Combination will be successful.

Proposed Business Combination

Business Combination Agreement

On September 8, 2021, we entered into the Business Combination Agreement with Merger Sub and Energy Vault, pursuant to which we will affect the Business Combination.

216

TABLE OF CONTENTS

Pursuant to the Business Combination Agreement, at Closing, Merger Sub will be merged with and into Energy Vault, with Energy Vault surviving the Merger as a wholly-owned direct subsidiary of us. At the Effective Time, by virtue of the Merger and without any action on the part of Novus, Merger Sub, Energy Vault or the holders of any of Energy Vault’s securities:

•

all of the then issued and outstanding shares of Energy Vault Common Stock (expressed on a fully diluted basis) will be cancelled and automatically convert into up to 106,566,033 shares of common stock of Novus;

•

(“Korea Zinc”) for the sale of an additional 5,000,000 shares of Novus Common Stock at a price of $10.00 per share for additional gross proceeds of $50 million in the PIPE. On September 3, 2021, Palantir and Energy Vault entered into an agreement (the “Software Agreement”) under which Energy Vault has agreed to purchase a Palantir Foundry cloud subscription (which provides advanced data analytics capability), including support services, updates and related professional services, from Palantir for $7.5 million payable over a term of two and a half years, beginning on December 1, 2021. Energy Vault may terminate the Software Agreement by giving written notice to Palantir within 20 business days of (a) the final expiration of termination of the Subscription Agreement with Palantir before the consummation of such agreement or (b) the failure of the Business Combination to close for any reason. In the event of a termination, Energy Vault shall only owe fees incurred under the Software Agreement before the effective date of termination and any fees relating to infrastructure costs incurred before the effective date of termination. On December 29, 2021, Energy Vault and Sun Metals Corporation Pty. Ltd.

TABLE OF CONTENTS

Results of Operations

We have neither engaged in any operations nor generated any operating revenues to date. Our only activities from inception through September 30, 2021 were organizational activities and those necessary to prepare for the IPO, described below, and our search for a target business for a business combination. We do not expect to generate any operating revenues until after the completion of our initial business combination. We generate non-operating income in the form of interest income on marketable securities held after the IPO. We incur increased expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses in connection with searching for, and completing, a business combination.

For the period from September 29, 2020 (inception) through December 31, 2020, we had a net loss of $1,104, which consisted of formation and operating expenses.

For the nine months ended September 30, 2021, we incurred a net loss of $568,873, which consisted of operating and formation costs of $779,783, and transaction costs incurred in connection with warrant liability of $241,311, offset by the change in fair value of the warrants of $442,500 and interest earned on marketable securities held in Trust account of $9,721.

Liquidity and Capital Resources

On February 8, 2021, we consummated our IPO of 28,750,000 Units, at a price of $10.00 per unit, which included the full exercise by the underwriters of their over-allotment option in the amount of 3,750,000 units, generating gross proceeds of $287,500,000. Simultaneously with the closing of our IPO, we consummated the sale of 5,166,666 Private Warrants to Novus’s initial stockholders, including Cowen Investments (an affiliate of the underwriter in our IPO) at a price of $1.50 per Private Warrant generating gross proceeds of $7,750,000.

Following our IPO, the full exercise of the over-allotment option, and the sale of the Private Warrants, a total of $287,500,000 was placed in the trust account. We incurred $6,224,714 in transaction costs, including $5,750,000 of underwriting fees and $474,714 of other offering costs.

For the nine months ended September 30, 2021, cash used in operating activities was $667,597. Net loss of $568,873 was affected by interest earned on marketable securities held in the Trust Account of $9,721, change in fair value of warrants of $442,500 and transaction costs incurred in connection with warrant of $241,311. Changes in operating assets and liabilities used $112,186 of cash for operating activities.

As of September 30, 2021, we had cash of $882,585. We intend to use substantially all of the funds held in the trust account, including any amounts representing interest earned on the trust account (less income taxes payable), to complete our business combination. To the extent that our capital stock or debt is used, in whole or in part, as consideration to complete our business combination, the remaining proceeds held in the trust account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies.

We intend to use the funds held outside the trust account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, and structure, negotiate and complete a business combination.

In order to fund working capital deficiencies or finance transaction costs in connection with a business combination, our founders or affiliates of our founders or certain of our officers and directors may, but are not obligated to, loan us funds as may be required. If we complete a business combination, we may repay such loaned amounts out of the proceeds of the trust account released to us. In the event that a business combination does not close, we may use a portion of the working capital held outside the trust account to repay such loaned amounts, but no proceeds from our trust account would be used for such repayment. Up to $2,000,000 of such loans may be convertible into warrants, at a price of $1.50 per warrant, at the option of the lender. The warrants would be identical to the Private Warrants.

219

TABLE OF CONTENTS

We do not believe we will need to raise additional funds in order to meet the expenditures required for operating our business. However, if our estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a business combination are less than the actual amount necessary to do so, we may have insufficient funds available to operate our business prior to our business combination. Moreover, we may need to obtain additional financing either to complete our business combination or because we become obligated to redeem a significant number of our Public Shares upon consummation of our business combination, in which case we may issue additional securities or incur debt in connection with such business combination. Subject to compliance with applicable securities laws, we would only complete such financing simultaneously with the completion of our business combination. If we are unable to complete our business combination because we do not have sufficient funds available to us, we will be forced to cease operations and liquidate the trust account. In addition, following our business combination, if cash on hand is insufficient, we may need to obtain additional financing in order to meet our obligations.

Going Concern

In connection with Novus’s assessment of going concern considerations in accordance with Financial Accounting Standard Board’s Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” we have determined that the liquidity condition and date for mandatory liquidation and dissolution raise substantial doubt about Novus’s ability to continue as a going concern through at least one year from issuance date of these condensed consolidated financial statements. Novus’s condensed consolidated financial statements included in this Preliminary Proxy Statement and Preliminary Prospectus do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should Novus be unable to continue as a going concern.

Off-Balance Sheet Arrangements

We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of September 30, 2021. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. We have not entered into any off-balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any non-financial assets.

Contractual Obligations

We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than described below.

Cowen was entitled to a cash underwriting discount of $0.20 per Unit, or $5,750,000 which was paid upon the closing of our IPO.

We engaged Cowen as an advisor in connection with a business combination to assist us in holding meetings with our stockholders to discuss the potential business combination and the target business’ attributes, introduce us to potential investors that are interested in purchasing our securities in connection with a business combination, provide financial advisory services to assist us in our efforts to obtain any stockholder approval for the business combination and assist us with our press releases and public filings in connection with the business combination. We will pay Cowen a cash fee for such services upon the consummation of a business combination in an amount equal to, in the aggregate, 3.5% of the gross proceeds of our IPO.

We have engaged Goldman, Cowen and Guggenheim to act as co-placement agents in connection with the PIPE. We will pay the placement agents a fee of $ in connection with the PIPE. Pursuant to the engagement letter with Cowen, Cowen will receive an additional $7.5 million business combination fee upon the consummation of the Business Combination.

Related Party Transactions

Founder Shares

On October 12, 2020, our Founders purchased an aggregate of 7,187,500 shares of Novus Class B common stock (the “Founder Shares”) for an aggregate purchase price of $25,000. In connection with the Business Combination, our Founders have agreed to forfeit 718,750 Founder Shares upon the Closing.

220

TABLE OF CONTENTS

Our Founders have agreed, subject to certain limited exceptions, not to transfer, assign or sell any of the founder shares until the earlier to occur of: (1) one year after the completion of a business combination or (B) subsequent to a business combination, (x) if the last reported sale price of the Novus Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after a business combination, or (y) the date on which Novus completes a liquidation, merger, capital stock exchange or other similar transaction that results in all of Novus’s stockholders having the right to exchange their shares of common stock for cash, securities or other property.

Private Warrants

Simultaneously with the IPO, the founders purchased an aggregate of 5,166,666 Private Warrants at a price of $1.50 per Private Warrant ($7.75 million in the aggregate) in a private placement. Each Private Warrant entitles the holder to purchase one share of Novus Common Stock at a price of $11.50 per share, subject to adjustment. Proceeds from the Private Warrants were added to the net proceeds from the IPO held in the trust account. If we do not complete an initial business combination within 24 months from the closing of our IPO, or by February 8, 2023, the proceeds from the sale of the Private Warrants will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Warrants will expire worthless. The Private Warrants will be non-redeemable and exercisable on a cashless basis so long as they are held by our Founders or their permitted transferees.

Registration Rights

Pursuant to a registration rights agreement entered into on February 3, 2021, the holders of the Founder Shares, Private Warrants and any warrants that may be issued upon conversion of the Working Capital Loans (and any shares of Novus Common Stock issuable upon the exercise of the Private Warrants and warrants that may be issued upon conversion of Working Capital Loans) will have registration rights to require Novus to register a sale of any of the securities for resale (in the case of the Founder Shares, only after conversion to shares of Novus Common Stock). The holders of these securities are entitled to make up to three demands, excluding short form demands, that the we register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of a business combination and rights to require us to register for resale such securities pursuant to Rule 415 under the Securities Act. Notwithstanding the foregoing, Cowen Investments may not exercise its demand and “piggyback” registration rights after five and seven years, respectively, after the effective date of our IPO. The registration rights agreement does not contain liquidating damages or other cash settlement provisions resulting from delays in registering our securities. We will bear the expenses incurred in connection with the filing of any such registration statements.

Promissory Note and Potential Related Party Loans

On October 1, 2020, certain of our directors agreed to loan us an aggregate of up to $300,000 to cover expenses related to our IPO pursuant to promissory notes (the “Promissory Notes”). From October 1, 2020 through December 31, 2020, we borrowed an aggregate of $160,000 under the Promissory Notes. The Promissory Notes are non-interest bearing and were payable on the earlier of (i) September 30, 2021 and (ii) the consummation of our IPO. The outstanding balance under the Promissory Notes was fully repaid on February 10, 2021.

In order to finance transaction costs in connection with a business combination, our founders or certain of our directors and officers may, but are not obligated to, loan us funds as may be required (“Working Capital Loans”). If we complete a business combination, the we would repay the Working Capital Loans out of the proceeds of the Trust Account released to us. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a business combination does not close, we may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of a business combination, without interest, or, at the lender’s discretion,

221

TABLE OF CONTENTS

up to $2,000,000 of such Working Capital Loans may be convertible into warrants of the post-business combination entity at a price of $1.50 per warrant. The warrants would be identical to the Private Warrants.

Underwriter’s Agreement

Cowen was entitled to a cash underwriting discount of $0.20 per unit in connection with the IPO and were paid $5,750,000 upon the closing of our IPO.

Business Combination Marketing Agreement

Certain Engagements in Connection with the Business Combination and Related Transactions

Cowen has acted as a financial advisors to Novus in connection with the Business Combination. In addition, Cowen was the sole underwriter on the IPO of Novus. Further, NCCI Co-Invest, an affiliate of Cowen, is the beneficial owner of approximately 1.6% of Novus’s outstanding common stock via ownership of Class B common stock and unexercisable warrants. At the time of its IPO, Novus also engaged Cowen to provide marketing services and Cowen will receive compensation in connection therewith contingent upon the closing of the Business Combination. Novus also engaged Cowen to act as co-placement agent for the PIPE. Cowen will receive fees and expense reimbursements in connection therewith. In addition, Cowen (together with its affiliates) is a full-service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investing, hedging, market making, brokerage and other financial and non-financial activities and services. From time to time, Cowen and its affiliates may have provided various investment banking and other commercial dealings unrelated to the Business Combination or the PIPE to Novus and its affiliates, and may have received customary compensation in connection therewith. In addition, Cowen and its affiliates may provide investment banking and other commercial dealings to Novus, Energy Vault and their respective affiliates in the future, for which they would expect to receive customary compensation.

In addition, in the ordinary course of its business activities, Cowen and its affiliates, officers, directors and employees may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of Novus, Energy Vault or their respective affiliates. Cowen and its affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Other Arrangements

No compensation or fees of any kind will be paid to the Novus Initial Stockholders, members of our management team or their respective affiliates, for services rendered prior to or in connection with the consummation of our initial business combination (regardless of the type of transaction that it is). However, such individuals will receive reimbursement for any out-of-pocket expenses incurred by them in connection with activities on our behalf, such as identifying potential target businesses, performing business due diligence on suitable target businesses and business combinations as well as traveling to and from the offices, plants or similar locations of prospective target businesses to examine their operations. There is no limit on the amount of out-of-pocket expenses reimbursable by us.

222

TABLE OF CONTENTS

After our initial business combination, members of our management team who remain with us may be paid consulting, management or other fees from the Combined Company with any and all amounts being fully disclosed to stockholders, to the extent then known, in the proxy solicitation materials furnished to our stockholders. However, the amount of such compensation may not be known at the time of the stockholder meeting held to consider an initial business combination, as it will be up to the directors of the post-combination business to determine executive and director compensation. In this event, such compensation will be publicly disclosed at the time of its determination in a Current Report on Form 8-K or a periodic report, as required by the SEC.

All ongoing and future transactions between us and any of our officers and directors or their respective affiliates will be on terms believed by us to be no less favorable to us than are available from unaffiliated third parties. Such transactions will require prior approval by a majority of our uninterested “independent” directors or the members of our board who do not have an interest in the transaction, in either case who had access, at our expense, to our attorneys or independent legal counsel. We will not enter into any such transaction unless our disinterested “independent” directors determine that the terms of such transaction are no less favorable to us than those that would be available to us with respect to such a transaction from unaffiliated third parties.

Critical Accounting Policies and Significant Judgments and Estimates

This discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. In accordance with GAAP, we base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. We have identified the following critical accounting policies:

Common Stock Subject to Possible Redemption

We account for our common stock subject to possible conversion in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within our control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. Our common stock features certain redemption rights that are considered to be outside of our control and subject to occurrence of uncertain future events. Accordingly, common stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders’ equity section of our condensed balance sheets.

Net loss Per Common Share

We apply the two-class method in calculating loss per share. Common stock subject to possible redemption which is not currently redeemable and is not redeemable at fair value, has been excluded from the calculation of basic net loss per common share since such shares, if redeemed, only participate in their pro rata share of the Trust Account earnings. Our net loss is adjusted for the portion of loss that is attributable to common stock subject to possible redemption, as these shares only participate in the earnings of the Trust Account and not our income or losses.

Recent Accounting Standards

TABLE OF CONTENTS

to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted. The Company is currently assessing the impact, if any, that ASU 2020-06 would have on its financial position, results of operations or cash flows.

Management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on our condensed financial statements.

Emerging Growth Company

Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. Novus has elected not to opt out of such extended transition period, which means that when a standard is issued or revised, and it has different application dates for public or private companies, Novus, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard.

This may make comparison of Novus’s financial statement with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Income Taxes

We follow the asset and liability method of accounting for income taxes under FASB ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

FASB ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. There were no unrecognized tax benefits as of September 30, 2020. We recognize accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties for the period from March 5, 2020 (date of inception) to September 30, 2020. Novus is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. We are subject to income tax examinations by major taxing authorities since inception.

Novus may be subject to potential examination by federal, state and city taxing authorities in the areas of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with federal, state and city tax laws. On December 22, 2017, the Tax Act was signed into legislation. As part of the legislation, the U.S. corporate income tax rate was reduced from 35% to 21%, among other changes.

Recent Accounting Pronouncements

Our management does not believe that there are any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on our financial statements.

Other Arrangements

Related Party Policy

Our Code of Ethics requires us to avoid, wherever possible, all related party transactions that could result in actual or potential conflicts of interests, except under guidelines approved by the board of directors

(or the audit committee). Related-party transactions are defined as transactions in which (1) the aggregate amount involved will or may be expected to exceed $120,000 in any calendar year, (2) we or any of our subsidiaries is a participant, and (3) any (a) executive officer, director or nominee for election as a director, (b) greater than 5% beneficial owner of our shares of common stock, or (c) immediate family member, of the persons referred to in clauses (a) and (b), has or will have a direct or indirect material interest (other than solely as a result of being a director or a less than 10% beneficial owner of another entity). A conflict of interest situation can arise when a person takes actions or has interests that may make it difficult to perform his or her work objectively and effectively. Conflicts of interest may also arise if a person, or a member of his or her family, receives improper personal benefits as a result of his or her position.

Our audit committee, pursuant to its written charter, is responsible for reviewing and approving related-party transactions to the extent we enter into such transactions. The audit committee considers all relevant factors when determining whether to approve a related party transaction, including whether the related party transaction is on terms no less favorable to us than terms generally available from an unaffiliated third-party under the same or similar circumstances and the extent of the related party’s interest in the transaction. No director may participate in the approval of any transaction in which he is a related party, but that director is required to provide the audit committee with all material information concerning the transaction. We also require each of our directors and executive officers to complete a directors’ and officers’ questionnaire that elicits information about related party transactions.

These procedures are intended to determine whether any such related party transaction impairs the independence of a director or presents a conflict of interest on the part of a director, employee or officer.

To further minimize conflicts of interest, we have agreed not to consummate an initial business combination with an entity that is affiliated with any of the Novus Initial Stockholders, officers or directors unless we have obtained an opinion from an independent investment banking firm, or another independent entity that commonly renders valuation opinions, that the Business Combination is fair to our unaffiliated stockholders from a financial point of view. We will also need to obtain approval of a majority of our disinterested independent directors.

Board Composition

Novus’s board of directors is currently authorized to have six members and currently consists of six members including Robert J. Laikin, Larry Paulson, Hersch Klaff, Jeffrey Foster, Heather Goodman and Ronald J. Sznaider. Pursuant to the Business Combination Agreement, all of Novus’s current directors will no longer be members of the Combined Company’s Board immediately after the Effective Time and will resign at or prior to the Effective Time. In accordance with the Proposed Second A&R Charter and second amended and restated bylaws that will be in effect upon the consummation of the Business Combination, the Combined Company’s board of directors will be comprised of six directors and will be divided into three classes with staggered three-year terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. The Combined Company’s directors will be divided among the three classes as follows:

•

the Class I directors will be Larry Paulson and Mary Beth Mandanas, and their terms will expire at the first annual meeting to be held after the consummation of the Business Combination;

•

the Class II directors will be Zia Huque, Henry Elkus and Thomas Ertel, and their terms will expire at the second annual meeting to be held after the consummation of the Business Combination; and

•

the Class III directors will be Robert Piconi and Bill Gross, and their terms will expire at the third annual meeting to be held after the consummation of the Business Combination.

Directors in a particular class will be elected for three-year terms at the annual meeting of stockholders in the year in which their terms expire. As a result, only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Each director’s term continues until the election and qualification of his or her successor, or the earlier of his or her death, resignation or removal.

The Proposed Certificate of Incorporation and amended and restated bylaws that will be in effect upon the completion of this offering provided that only the Combined Company Board can fill vacant directorships, including newly-created seats. Any additional directorships resulting from an increase in the authorized number of directors would be distributed pro rata among the three classes so that, as nearly as possible, each class would consist of one-third of the authorized number of directors.

Director Independence

Upon the consummation of the Business Combination, the Combined Company Board anticipates that each of its members, other than Robert Piconi, will qualify as independent, as defined under the listing rules of the NYSE. In addition, the Combined Company will be subject to the rules of the SEC and NYSE relating to the memberships, qualifications and operations of the audit committee, as discussed below.

Role of the Combined Company Board in Risk Oversight

Upon the Closing, one of the key functions of the Combined Company Board will be informed oversight of the Combined Company’s risk management process. The Combined Company Board does not anticipate having a standing risk management committee, but rather anticipates administering this oversight function directly through the Combined Company Board as a whole, as well as through various standing committees of the Combined Company Board that address risks inherent in their respective areas of oversight. For example, the Combined Company audit committee will be responsible for overseeing the

232

management of risks associated with the Combined Company’s financial reporting, accounting and auditing matters, and the compensation committee will oversee the management of risks associated with the Combined Company’s compensation policies and programs.

Board Committees

The Combined Company Board and its committees will set schedules for meeting throughout the year and can also hold special meetings and act by written consent from time to time, as appropriate. The Combined Company Board will delegate various responsibilities and authority to its committees as generally described below. The committees will regularly report on their activities and actions to the full board of directors. Each member of each committee of the Combined Company Board is expected to qualify as an independent director in accordance with the listing standards of the NYSE.

Audit Committee

Upon the consummation of the Business Combination, the members of the audit committee will be Thomas Ertel, Mary Beth Mandanas and Zia Huque, each of whom can read and understand fundamental financial statements. The Combined Company Board has determined that each of Mr. Ertel, Ms. Mandanas and Mr. Huque is independent under the rules and regulations of the SEC and the listing standards of the NYSE applicable to audit committee members. Mr. Ertel will be the chair of the audit committee. The Combined Company Board has determined that each of Mr. Ertel, Ms. Mandanas and Mr. Huque qualify as an audit committee financial expert within the meaning of SEC regulations and meet the financial sophistication requirements of the NYSE. The Combined Company’s audit committee will assist the Combined Company Board with its oversight of the following: the integrity of the Combined Company’s financial statements; the Combined Company’s compliance with legal and regulatory requirements; the qualifications, independence, and performance of the Combined Company’s independent registered public accounting firm; the design and implementation of the Combined Company’s internal audit function and risk assessment and risk management. Among other things, the Combined Company’s audit committee will be responsible for reviewing and discussing with the Combined Company’s management the adequacy and effectiveness of the Combined Company’s disclosure controls and procedures. The audit committee will also discuss with the Combined Company’s management and independent registered public accounting firm the annual audit plan and scope of audit activities, scope and timing of the annual audit of the Combined Company’s financial statements, and the results of the audit, quarterly reviews of the Combined Company’s financial statements and, as appropriate, will initiate inquiries into certain aspects of the Combined Company’s financial affairs. The Combined Company’s audit committee will be responsible for establishing and overseeing procedures for the receipt, retention, and treatment of any complaints regarding accounting, internal accounting controls or auditing matters, as well as for the confidential and anonymous submissions by the Combined Company’s employees of concerns regarding questionable accounting or auditing matters. In addition, the Combined Company’s audit committee will have direct responsibility for the appointment, compensation, retention, and oversight of the work of the Combined Company’s independent registered public accounting firm. The Combined Company’s audit committee will have sole authority to approve the hiring and discharging of the Combined Company’s independent registered public accounting firm, all audit engagement terms and fees, and all permissible non-audit engagements with the independent auditor.

Non-Employee Director Compensation

During 2020, no director received cash, equity or other non-equity compensation for service on Novus’s board of directors. Novus currently has no formal arrangements under which directors receive compensation for their service on Novus’s board of directors or its committees. Novus’s policy is to reimburse directors for reasonable and necessary out-of-pocket expenses incurred in connection with attending board and committee meetings or performing other services in their capacities as directors.

The Combined Company Board is expected to review director compensation periodically to ensure that director compensation remains competitive such that the Combined Company is able to recruit and retain qualified directors. Following the consummation of the Business Combination, the Combined Company intends to develop a director compensation program that is designed to align compensation with its business objectives and the creation of stockholder value, while enabling the Combined Company to attract, retain, incentivize and reward directors who contribute to the long-term success of the Combined Company.

The outstanding shares of Novus Common Stock and Novus Class B Common Stock are, and the shares of Combined Company Common Stock issued in the Business Combination will be, duly authorized, validly issued, fully paid and non-assessable. As of the Record Date for the special meeting, there were 28,750,000 shares of Novus Common Stock held by [*] stockholders of record, 7,187,500 shares of Novus Class B Common Stock and no shares of preferred stock of Novus outstanding, including holders of record of Novus Units.

Combined Company Common Stock Following the Business Combination

Voting Power

Except as otherwise required by law or as otherwise provided in any certificate of designation for any series of preferred stock, the holders of Combined Company Common Stock possess all voting power for the election of our directors and all other matters requiring stockholder action. Holders of Combined Company Common Stock are entitled to one vote per share on matters to be voted on by stockholders.

Dividends

Holders of Combined Company Common Stock will be entitled to receive such dividends, if any, as may be declared from time to time by our board of directors in its discretion out of funds legally available therefor. In no event will any stock dividends or stock splits or combinations of stock be declared or made on Combined Company Common Stock unless the shares of Combined Company Common Stock at the time outstanding are treated equally and identically.

Liquidation, Dissolution and Winding Up

In the event of our voluntary or involuntary liquidation, dissolution, distribution of assets or winding-up, the holders of the Combined Company Common Stock will be entitled to receive an equal amount per share of all of our assets of whatever kind available for distribution to stockholders, after the rights of the holders of the preferred stock, if any, have been satisfied.

Preemptive or Other Rights

Our stockholders have no preemptive or other subscription rights and there are no sinking fund or redemption provisions applicable to Combined Company Common Stock.

Election of Directors

Following the Business Combination, the Combined Company Board will be divided into three classes, each of which will generally serve for a term of three years with only one class of directors being elected in each year. Unless required by applicable law at the time of election, there is no cumulative voting with respect to the election of directors, with the result that the holders of more than 50% of the shares voted for the election of directors can elect all of the directors.

TABLE OF CONTENTS

Novus Common Stock Prior to the Business Combination

We are providing stockholders with the opportunity to redeem their shares upon the consummation of the Business Combination at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest but net of taxes payable, divided by the number of then outstanding Public Shares, subject to the limitations described herein. In connection with the IPO and for no additional consideration, all of the Founders, including the Novus Initial Stockholders, agreed to waive their redemption rights with respect to all of the Founder Shares held by them at the closing of the IPO and the Novus Initial Stockholders, have agreed to waive their redemption rights with respect to any Public Shares that they may have acquired during or after our IPO in connection with the completion of our Business Combination.

We will consummate the Business Combination only if a majority of the outstanding shares of Novus Common Stock voted at the special meeting are voted in favor of the Business Combination Proposal. However, the participation of Novus’s officers, directors, advisors or their affiliates in privately-negotiated transactions (as described in this proxy statement/prospectus), if any, could result in the approval of the Business Combination even if a majority of the remaining stockholders vote, or indicate their intention to vote, against the Business Combination.

The Founders have agreed to vote the Founder Shares and any Public Shares purchased during or after the IPO in favor of the Business Combination. Public stockholders may elect to redeem their Public Shares whether they vote for or against the Business Combination.

Pursuant to the Existing Certificate of Incorporation, if we are unable to complete our initial business combination by February 8, 2023 or obtain the approval of Novus’s stockholders to extend the deadline for us to consummate an initial business combination, we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than 10 business days thereafter, subject to lawfully available funds therefor, redeem the Public Shares, at a per share price which is payable in cash and equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable by us) divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our board of directors, dissolve and liquidate, subject in each case to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Our Founders, executive officers and directors have entered into a letter agreement with us, pursuant to which they have agreed to (1) waive their redemption rights with respect to any common stock held by them in connection with the completion of our initial business combination or any amendment to the provisions of the Existing Certificate of Incorporation relating to our pre-initial business combination activity and related stockholders’ rights and (2) waive their rights to liquidating distributions from the Trust Account with respect to their Founder Shares if we fail to complete our business combination within the prescribed timeframe (although they will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares they hold).

Holders of Novus Common Stock have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the Novus Common Stock, except that we will provide our stockholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of the Business Combination at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination, including interest earned on the funds held in the Trust Account (which interest shall be net of taxes payable by us), divided by the number of then outstanding Public Shares, subject to the limitations described herein.

Our board of directors is currently divided into three classes, each of which generally serves for a term of three years with only one class of directors being elected in each year. In accordance with the terms of the Existing Certificate of Incorporation, the classification of the board of directors expires on its terms upon consummation of the Business Combination.

Pursuant to the Existing Certificate of Incorporation, any action required or permitted to be taken by Novus’s stockholders must be effected by a duly called annual or special meeting of such holders and may

236

TABLE OF CONTENTS

not be effected by written consent of Novus’s Stockholders other than with respect to the Novus Class B Common Stock with respect to which action may be taken by written consent.

Founder Shares

The Founder Shares are identical to the shares of Novus Common Stock except that: (1) prior to our initial business combination, only holders of the Novus Class B Common Stock have the right to vote on the election of directors and holders of a majority of the outstanding shares of Novus Class B Common Stock may remove members of our board of directors for any reason; (2) our initial stockholders, officers and directors have entered into a letter agreement with us, pursuant to which they have agreed for no additional consideration to waive: (a) their redemption rights with respect to any Founder Shares and any Public Shares held by them in connection with the completion of our initial business combination, (b) their redemption rights with respect to any Founder Shares and Public Shares held by them in connection with a stockholder vote to approve an amendment to our amended and restated certificate of incorporation (A) to modify the substance or timing of our obligation to allow redemptions in connection with our initial business combination or to redeem 100% of our Public Shares if we have not consummated our initial business combination within 24 months from the closing of our IPO or (B) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity; and (c) their rights to liquidating distributions from the trust account with respect to any Founder Shares held by them if we fail to complete our initial business combination within 24 months from the closing of our IPO or during any Extension Period (although they will be entitled to liquidating distributions from the trust account with respect to any Public Shares they hold if we fail to complete our initial business combination within the prescribed time frame); (3) the Founder Shares are subject to certain transfer restrictions, as described in more detail below; (4) the Founder Shares are automatically convertible into shares of our Novus Common Stock at the time of our initial business combination, or earlier at the option of the holder, on a one-for-one basis, subject to adjustment pursuant to certain anti-dilution rights, as described herein; and (5) the holders of Founder Shares are entitled to registration rights. If we submit our initial business combination to our public stockholders for a vote, our initial stockholders, officers and directors have agreed (and their permitted transferees, as applicable, will agree) to vote any Founder Shares and any Public Shares held by them in favor of our initial business combination.

The shares of Novus Class B Common Stock will automatically convert into shares of Novus Common Stock at the time of our initial business combination, or earlier at the option of the holder, on a one-for-one basis, subject to adjustment as provided herein. In the case that additional shares of Novus Common Stock, or equity-linked securities, are issued or deemed issued in excess of the amounts issued in our IPO and related to the closing of our initial business combination, the ratio at which shares of Novus Class B Common Stock shall convert into shares of Novus Common Stock will be adjusted (unless the holders of a majority of the outstanding shares of our Novus Class B Common Stock agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Novus Common Stock issuable upon conversion of all shares of Novus Class B Common Stock will equal, in the aggregate, on an as-converted basis, 20% of the total number of all shares of common stock outstanding at the completion of our IPO plus all shares of Novus Common Stock and equity-linked securities issued or deemed issued in connection with our initial business combination (net of the number of shares of Novus Common Stock redeemed in connection with our initial business combination), excluding any shares or equity-linked securities issued, or to be issued, to any seller in our initial business combination.

With certain limited exceptions, the Founder Shares are not transferable, assignable or salable (except to our officers and directors and other persons or entities affiliated with our Founders, each of whom will be subject to the same transfer restrictions) until the earlier of (A) one year after the completion of our initial business combination, (B) subsequent to our initial business combination, (x) the date on which we complete a liquidation, merger, stock exchange, reorganization or other similar transaction that results in all of our Public Stockholders having the right to exchange their shares of Common Stock for cash, securities or other property or (y) if the last reported sale price of our Novus Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing after our initial business combination.

TABLE OF CONTENTS

Preferred Stock

Our amended and restated certificate of incorporation authorizes 5,000,000 shares of preferred stock and provides that shares of preferred stock may be issued from time to time in one or more series. Our board of directors are authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. Our board of directors are be able to, without stockholder approval, issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the common stock and could have anti-takeover effects. The ability of our board of directors to issue preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of us or the removal of existing management. We have no preferred stock outstanding at the date hereof. Although we do not currently intend to issue any shares of preferred stock, we cannot assure you that we will not do so in the future. No shares of preferred stock were registered in our IPO.

Novus has no preferred stock outstanding at the date hereof and will have no preferred stock outstanding immediately after the Closing.

Warrants

As of September 30, 2021, there were 14,749,999 Novus Warrants to purchase Novus Common Stock outstanding, consisting of 9,583,333 Public Warrants and 5,166,666 Private Warrants held by our Founders. Each Novus Warrant entitles the registered holder to purchase one share of Novus Common Stock at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing 30 days after the completion of our initial business combination. The Novus Warrants will expire at 5:00 p.m., New York City time, on the fifth anniversary of our completion of an initial business combination, or earlier upon redemption or liquidation.

Holders of our Public Warrants cannot pay cash to exercise of their Public Warrants unless we have an effective and current registration statement covering the issuance of the shares underlying such warrants and a current prospectus relating thereto. Notwithstanding the foregoing, if a registration statement covering the shares of common stock issuable upon exercise of the Public Warrants is not effective within a specified period following the consummation of our initial business combination, warrant holders may, until such time as there is an effective registration statement and during any period when we shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to the exemption provided by Section 3(a)(9) of the Securities Act, provided that such exemption is available. If that exemption, or another exemption, is not available, holders will not be able to exercise their warrants on a cashless basis. In the event of such cashless exercise, each holder would pay the exercise price by surrendering the warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” for this purpose will mean the average reported last sale price of the shares of common stock for the five trading days ending on the trading day prior to the date of exercise. The Novus Warrants will expire on the fifth anniversary of our completion of an initial business combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

The Private Warrants, as well as any warrants underlying additional units we issue to the Founders, officers, directors or their affiliates in payment of working capital loans made to us, will be identical to the warrants underlying the units being offered by this proxy statement/prospectus except that such warrants will be exercisable for cash or on a cashless basis, at the holder’s option, and will not be redeemable by us, in each case so long as they are still held by the Founders or their permitted transferees.

We may call the Novus Warrants for redemption (excluding the private warrants and any warrants underlying additional units issued to the Founders, officers, directors or their affiliates in payment of working capital loans made to us), in whole and not in part, at a price of $0.01 per warrant,

•

at any time after the warrants become exercisable;

•

upon not less than 30 days’ prior written notice of redemption to each warrant holder;

238

TABLE OF CONTENTS

•

if, and only if, the reported last sale price of the shares of the Novus Common Stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations), for any 20 trading days within a 30 trading day period commencing at any time after the warrants become exercisable and ending on the third trading day prior to the notice of redemption to warrant holders; and

•

if, and only if, there is a current registration statement in effect with respect to the shares of common stock underlying such warrants.

If we call the Novus Warrants for redemption at a time the warrants meet the redemption criteria as described above, our management will have the option to require all holders that wish to exercise Novus Warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the Novus Warrants for that number of shares of Novus Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Novus Common Stock underlying the warrants, multiplied by the difference between the exercise price of the Novus Warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” for this purpose shall mean the average reported last sale price of the shares of common stock for the five (5) trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants.

We have established the $18.00 per share (as adjusted) redemption criteria discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the Novus Warrants, each warrant holder will be entitled to exercise its Novus Warrant prior to the scheduled redemption date. However, the price of the Novus Common Stock may fall below the $18.00 redemption trigger price (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) as well as the $11.50 warrant exercise price after the redemption notice is issued.

In addition to the warrant redemption described above, we may redeem the Novus Warrants commencing ninety days after the Novus Warrants become exercisable, (except as described herein with respect to the private placement warrants):

•

in whole and not in part;

•

at a price of $0.10 per warrant provided that holders will be able to exercise their warrants prior to redemption and receive that number of shares of Novus Common Stock determined by reference to the table below, based on the redemption date and the “fair market value” (as defined below) of our Novus Common Stock except as otherwise described below;

•

upon a minimum of 30 days’ prior written notice of redemption;

•

if, and only if, the last reported sale price of our Novus Common Stock equals or exceeds $10.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) on the trading day prior to the date on which we send the notice of redemption to the warrant holders; and

•

if, and only if, there is an effective registration statement covering the issuance of the shares of Novus Common Stock issuable upon exercise of the Novus Warrants and a current prospectus relating thereto available throughout the 30-day period after written notice of redemption is given.

The numbers in the table below represent the number of shares of Novus Common Stock that a warrant holder will receive upon cashless exercise in connection with a redemption by us pursuant to this redemption feature, based on the “fair market value” of Novus Common Stock on the corresponding redemption date (assuming holders elect to exercise their warrants and such warrants are not redeemed for $0.10 per warrant), determined based on the average of the last reported sales price for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants, and the number of months that the corresponding redemption date precedes the expiration date of the warrants, each as set forth in the table below.

Pursuant to the warrant agreement, references above to Novus Common Stock shall include a security other than Novus Common Stock into which the Novus Common Stock has been converted or exchanged

239

TABLE OF CONTENTS

for in the event we are not the surviving company in our initial business combination. The numbers in the tables below will not be adjusted solely as a result of us not being the surviving entity following our initial business combination.

The stock prices set forth in the column headings of the table below will be adjusted as of any date on which the number of shares issuable upon exercise of a Novus Warrant is adjusted as set forth in the first three paragraphs under the heading “— Anti-dilution Adjustments” below. The adjusted stock prices in the column headings will equal the stock prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the number of shares deliverable upon exercise of a Novus Warrant immediately prior to such adjustment and the denominator of which is the number of shares deliverable upon exercise of a Novus Warrant as so adjusted. The number of shares in the table below shall be adjusted in the same manner and at the same time as the number of shares issuable upon exercise of a Novus Warrant.

The exact fair market value and redemption date may not be set forth in the table above, in which case, if the fair market value is between two values in the table or the redemption date is between two redemption dates in the table, the number of shares of Novus Common Stock to be issued for each Novus Warrant exercised will be determined by a straight-line interpolation between the number of shares set forth for the higher and lower fair market values and the earlier and later redemption dates, as applicable, based on a 365 or 366-day year, as applicable. For example, if the average last reported sale price of our Novus Common Stock for the 10 trading days ending on the third trading date prior to the date on which the notice of redemption is sent to the holders of the Novus Warrants is $11 per share, and at such time there are 57 months until the expiration of the warrants, holders may choose to, in connection with this redemption feature, exercise their Novus Warrants for 0.277 shares of Novus Common Stock for each whole warrant. For an example where the exact fair market value and redemption date are not as set forth in the table above, if the average last reported sale price of our Novus Common Stock for the 10 trading days ending on the third trading date prior to the date on which the notice of redemption is sent to the holders of the Novus Warrants is $13.50 per share, and at such time there are 38 months until the expiration of the Novus Warrants,

240

TABLE OF CONTENTS

holders may choose to, in connection with this redemption feature, exercise their Novus Warrants for 0.298 shares of Novus Common Stock for each whole warrant. In no event will the Novus Warrants be exercisable in connection with this redemption feature for more than 0.361 shares of Novus Common Stock per warrant (subject to adjustment). Finally, as reflected in the table above, if the Novus Warrants are out of the money and about to expire, they cannot be exercised on a cashless basis in connection with a redemption by us pursuant to this redemption feature, since they will not be exercisable for any shares of Novus Common Stock.

Any Public Warrants held by our officers or directors will be subject to this redemption feature, except that such officers and directors shall only receive “fair market value” for such Public Warrants if they exercise their Public Warrants in connection with such redemption (“fair market value” for such Public Warrants held by our officers or directors being defined as the last reported sale price of the Public Warrants on such redemption date).

This redemption feature differs from the typical warrant redemption features used in many other blank check offerings, which typically only provide for a redemption of Novus Warrants for cash (other than the Private Warrants) when the trading price for the Novus Common Stock exceeds $18.00 per share for a specified period of time. This redemption feature is structured to allow for all of the outstanding Novus Warrants (other than the Private Warrants) to be redeemed when the Novus Common Stock is trading at or above $10.00 per share, which may be at a time when the trading price of the Novus Common Stock is below the exercise price of the warrants. We have established this redemption feature to provide us with the flexibility to redeem the warrants without the warrants having to reach the $18.00 per share threshold set forth above under “— Redemption of warrants when the price per share of Novus Common Stock equals or exceeds $18.00.” Holders choosing to exercise their Novus Warrants in connection with a redemption pursuant to this feature will, in effect, receive a number of shares for their warrants based on an option pricing model with a fixed volatility input as of the date of this prospectus. This redemption right provides us an additional mechanism by which to redeem all of the outstanding Novus Warrants, and therefore have certainty as to our capital structure as the Novus Warrants would no longer be outstanding and would have been exercised or redeemed, and we will effectively be required to pay the redemption price to warrant holders if we choose to exercise this redemption right and it will allow us to quickly proceed with a redemption of the warrants if we determine it is in our best interest to do so. As such, we would redeem the Novus Warrants in this manner when we believe it is in our best interest to update our capital structure to remove the Novus Warrants and pay the redemption price to the warrant holders.

As stated above, we can redeem the Novus Warrants when the Novus Common Stock is trading at a price starting at $10.00, which is below the exercise price of $11.50, because it will provide certainty with respect to our capital structure and cash position while providing warrant holders with the opportunity to exercise their Novus Warrants on a cashless basis for the applicable number of shares of Novus Common Stock. If we choose to redeem the warrants when the Novus Common Stock is trading at a price below the exercise price of the Novus Warrants, this could result in the warrant holders receiving fewer shares of Novus Common Stock than they would have received if they had chosen to wait to exercise their Novus Warrants for shares of Novus Common Stock if and when shares of Novus Common Stock were trading at a price higher than the exercise price of $11.50 per share.

In the event that we elect to redeem the Novus Warrants, we will fix a date for the redemption, and a notice of redemption will then be mailed by first class mail, postage prepaid, not less than 30 days prior to the date fixed for redemption to the registered holders of the warrants to be redeemed at their last addresses as they appear on the registration books. Any notice mailed in the foregoing manner will be conclusively presumed to have been duly given whether or not the registered holder received such notice. Additionally, while we are required to provide such notice of redemption, we are not separately required to, and do not currently intend to, notify any holders of when the warrants become eligible for redemption.

The right to exercise will be forfeited unless the Novus Warrants are exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder of a warrant will have no further rights except to receive the redemption price for such holder’s Novus Warrant upon surrender of such Novus Warrant.

TABLE OF CONTENTS

The Novus Warrants were issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. The warrant agreement provides that the terms of the Novus Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval, by written consent or vote, of the holders of at least a majority of the then outstanding Public Warrants and Private Warrants, if such modification or amendment is being undertaken prior to, or in connection with, the Closing, or Novus Warrants, if such modification or amendment is being undertaken after the Closing, in order to make any change that adversely affects the interests of the registered holders.

The exercise price and number of shares of Novus Common Stock issuable on exercise of the Novus Warrants may be adjusted in certain circumstances including in the event of a stock dividend, extraordinary dividend or our recapitalization, reorganization, merger or consolidation. However, except as described below, the Novus Warrants will not be adjusted for issuances of shares of Novus Common Stock at a price below their respective exercise prices.

In addition, if (x) we issue additional shares of Novus Common Stock or equity-linked securities for capital raising purposes in connection with the closing of our initial business combination at an issue price or effective issue price of less than $9.20 per share of Novus Common Stock (with such issue price or effective issue price to be determined in good faith by our board of directors, and in the case of any such issuance to the Founders or their affiliates, without taking into account any Founder Shares held by them prior to such issuance), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of our initial business combination on the date of the consummation of our initial business combination (net of redemptions), and (z) the “fair market value” (as defined below) is below $9.20 per share, the exercise price of the Novus Warrants will be adjusted (to the nearest cent) to be equal to 115% of the greater of (i) the fair market value or (ii) the price at which we issue the additional shares of common stock or equity-linked securities. The “fair market value” for this purpose shall mean the volume weighted average reported trading price of Novus Common Stock for the 20 trading days ending on the trading day prior to the date of the consummation of the Business Combination.

The Novus Warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the office of the warrant agent, with the subscription form, as set forth in the Novus Warrant, duly executed, accompanied by full payment of the exercise price, by certified or official bank check payable to the order of the warrant agent, for the number of Novus Warrants being exercised. The warrant holders do not have the rights or privileges of holders of shares of Novus Common Stock and any voting rights until they exercise their Novus Warrants and receive shares of Novus Common Stock. After the issuance of shares of Novus Common Stock upon exercise of the Novus Warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

Warrant holders may elect to be subject to a restriction on the exercise of their warrants such that an electing warrant holder would not be able to exercise their warrants to the extent that, after giving effect to such exercise, such holder would beneficially own in excess of 9.8% of the shares of common stock outstanding.

Dividends

We have not paid any cash dividends on our shares of Novus Common Stock or Novus Class A Common Stock to date and do not intend to pay cash dividends prior to the completion of a business combination. The payment of cash dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements and general financial condition subsequent to completion of a business combination. The payment of any dividends subsequent to a business combination will be within the discretion of our then board of directors. It is the present intention of our board of directors to retain all earnings, if any, for use in our business operations and, accordingly, our board of directors does not anticipate declaring any dividends in the foreseeable future.

Certain Anti-Takeover Provisions of Delaware Law

Consistent with the Existing Certificate of Incorporation, we will not opt out of Section 203 of the DGCL under the Proposed Certificate of Incorporation. Under Section 203 of the DGCL, the Combined

242

TABLE OF CONTENTS

Company will be prohibited from engaging in any Business Combination with any stockholder for a period of three years following the time that such stockholder (the “interested stockholder”) came to own at least 15% of the outstanding voting stock of the Combined Company (the “acquisition”), except if:

•

the Combined Company Board approved the acquisition prior to its consummation;

•

the interested stockholder owned at least 85% of the outstanding voting stock upon consummation of the acquisition; or

•

the Business Combination is approved by the Combined Company Board, and by a 2/3 majority vote of the other stockholders in a meeting.

Generally, a “business combination” includes any merger, consolidation, asset or stock sale or certain other transactions resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an “interested stockholder” is a person who, together with that person’s affiliates and associates, owns, or within the previous three years owned, 15% or more of our voting stock.

Under certain circumstances, declining to opt out of Section 203 of the DGCL will make it more difficult for a person who would be an “interested stockholder” to effect various business combinations with the Combined Company for a three-year period. This may encourage companies interested in acquiring the Combined Company to negotiate in advance with the Combined Company Board because the stockholder approval requirement would be avoided if the Combined Company Board approves the acquisition which results in the stockholder becoming an interested stockholder. This may also have the effect of preventing changes in the Combined Company Board and may make it more difficult to accomplish transactions which stockholders may otherwise deem to be in their best interests.

Special Meeting of Stockholders

Our current bylaws provide that special meetings of our stockholders may be called only by a majority vote of our board of directors, by our president or by our chairman or by our secretary at the request in writing of stockholders owning a majority of our issued and outstanding capital stock entitled to vote. The bylaws that will be in effect upon consummation of the Business Combination provide that special meetings of our stockholders may be called by the chairperson of our board of directors, our Chief Executive Officer and our board of directors pursuant to adoption of a resolution.

Advance Notice Requirements for Stockholder Proposals and Director Nominations

Our current bylaws provide, and the bylaws to be in effect upon consummation of the Business Combination will provide, that stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of stockholders must provide timely notice of their intent in writing. Our current bylaws, and the bylaws to be in effect upon consummation of the Business Combination, also specify certain requirements as to the form and content of a stockholders’ meeting. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders.

Written Consent by Stockholders

Under the Proposed Certificate of Incorporation, subject to the rights of any series of preferred stock then outstanding, any action required or permitted to be taken by the stockholders of the Combined Company must be effected at a duly called annual or special meeting of stockholders of the Combined Company and may not be effected by any consent in writing by such stockholders.

Authorized but Unissued Shares

Our authorized but unissued common stock and preferred stock are available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

243

TABLE OF CONTENTS

Exclusive Forum Selection

The Existing Certificate of Incorporation requires, to the fullest extent permitted by law, that derivative actions brought in our name, actions against directors, officers and employees for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the State of Delaware, except any action (A) as to which the Court of Chancery in the State of Delaware determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination), (B) which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, (C) for which the Court of Chancery does not have subject matter jurisdiction or (D) any action arising under the Securities Act, as to which the Court of Chancery and the federal district court for the District of Delaware shall have concurrent jurisdiction. If an action is brought outside of Delaware, the stockholder bringing the suit will be deemed to have consented to service of process on such stockholder’s counsel.

The Proposed Certificate of Incorporation provides that the Court of Chancery of the State of Delaware will be the exclusive forum for actions or proceedings brought under Delaware statutory or common law: (1) any derivative action or proceeding brought on our behalf; (2) any action asserting a breach of fiduciary duty; (3) any action asserting a claim against us arising under the Delaware General Corporation Law; (4) any action regarding the Existing Certificate of Incorporation or our amended and restated bylaws; (5) any action as to which the Delaware General Corporate Law confers jurisdiction to the Court of Chancery of the State of Delaware; or (6) any action asserting a claim against us that is governed by the internal affairs doctrine. The Proposed Certificate of Incorporation further provides that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act.

Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. As a result, the exclusive forum provision of the Existing Certificate of Incorporation and the Proposed Certificate of Incorporation will not apply to suits brought to enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction.

Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, a court may determine that this provision is unenforceable, and to the extent it is enforceable, the provision may have the effect of discouraging lawsuits against our directors and officers, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder and therefore bring a claim in another appropriate forum. Additionally, we cannot be certain that a court will decide that this provision is either applicable or enforceable, and if a court were to find the choice of forum provision contained in the Existing Certificate of Incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, operating results and financial condition.

Limitation on Liability and Indemnification of Directors and Officers

The Existing Certificate of Incorporation and the Proposed Certificate of Incorporation provide that our directors and officers will be indemnified by us to the fullest extent authorized by Delaware law as it now exists or may in the future be amended. In addition, the Existing Certificate of Incorporation and the Proposed Certificate of Incorporation provide that our directors will not be personally liable for monetary damages to us for breaches of their fiduciary duty as directors, unless they violated their duty of loyalty to us or our stockholders, acted in bad faith, knowingly or intentionally violated the law, authorized unlawful payments of dividends, unlawful stock purchases or unlawful redemptions, or derived an improper personal benefit from their actions as directors.

We will also enter into agreements with our officers and directors to provide contractual indemnification. Our current bylaws permit, and the bylaws to be in effect upon the consummation of the Business Combination will permit us to secure insurance on behalf of any officer, director or employee for any liability arising out of his or her actions, regardless of whether Delaware law would permit indemnification.

244

TABLE OF CONTENTS

We will purchase a policy of directors’ and officers’ liability insurance that insures our directors and officers against the cost of defense, settlement or payment of a judgment in some circumstances and insures us against our obligations to indemnify the directors and officers.

These provisions may discourage stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. Furthermore, a stockholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions. We believe that these provisions, the insurance and the indemnity agreements are necessary to attract and retain talented and experienced directors and officers.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

SHARES ELIGIBLE FOR FUTURE SALE

Upon completion of the Business Combination, Novus will have 500,000,000 shares of Novus Common Stock authorized and, based on the assumptions set out elsewhere in this proxy statement/prospectus, up to:

•

156,784,788 shares of Combined Company Common Stock issued and outstanding, assuming that no Public Stockholders exercise their redemption rights and that no Earn Out Shares are issued;

•

126,712,150 shares of Combined Company Common Stock issued and outstanding, assuming that 26,838,263 Public Shares are redeemed and that no Earn Out Shares are issued.

All of the shares of Combined Company Common Stock issued in connection with the Business Combination will be freely transferable by persons other than by Novus’s “affiliates” without restriction or further registration under the Securities Act. Sales of substantial amounts of the Combined Company Common Stock in the public market could adversely affect prevailing market prices of the Combined Company Common Stock. The foregoing assumes that no Earn Out Shares are issued.

Lock-up Agreements and Registration Rights

Pursuant to the terms of the Subscription Agreement, Combined Company is obligated to file a registration statement to register the resale of the Novus Common Stock purchased by the PIPE Subscribers.

In connection with the Closing, the Founders and certain stockholders of Energy Vault will agree, subject to certain exceptions, not to (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, and the rules and regulations of the SEC promulgated thereunder, the Lock-up Shares, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Lock-up Shares, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise or (iii) publicly announce any intention to effect any transaction specified in clause (i) or (ii). The Lock-Up Period shall terminate (i) with respect to 50% of the Lock-Up Shares, 180 days after the Closing and (ii) with respect to the remaining 50% of the Lock-Up Shares, one year after the Closing; provided however that the Lock-Up Period shall terminate 180 days after the Closing with respect to the Private Warrants and the shares of Combined Company Common Stock issuable upon exercise of the Private Warrants.

In connection with the Closing, that certain registration rights agreement dated February 2, 2021 will be amended and restated and Novus, and the Reg Rights Holders shall enter into the Registration Rights Agreement. Pursuant to the Registration Rights Agreement, Novus will agree that, within the later of 20 business days and 30 calendar days after the closing of the Business Combination, Novus will file with the SEC (at Novus’s sole cost and expense) the Resale Registration Statement, and Novus shall use commercially reasonable efforts to have the Resale Registration Statement declared effective as soon as practicable after the filing thereof. In certain circumstances, the New Holders can demand up to two underwritten offerings, and all of the Reg Rights Holders will be entitled to piggyback registration rights.

For more information about the Lock-Up Agreement and Registration Rights, see the section titled “Certain Agreements Related to the Business Combination — Lock-Up Agreements” and “Certain Agreements Related to the Business Combination — Registration Rights Agreement.”

Rule 144

A person who has beneficially owned restricted shares of Novus Common Stock or restricted Novus Warrants for at least six months would be entitled, subject to any applicable lock-up agreement, to sell their securities provided that (i) such person is not deemed to have been one of our affiliates at the time of, or at any time during the three months preceding, a sale and (ii) we are subject to the Exchange Act periodic reporting requirements for at least three months before the sale and have filed all required reports under Section 13 or 15(d) of the Exchange Act during the 12 months (or such shorter period as we were required to file reports) preceding the sale. Persons who have beneficially owned restricted shares of Novus Common

246

TABLE OF CONTENTS

Stock or restricted Novus Warrants for at least six months but who are our affiliates at the time of, or any time during the three months preceding, a sale, would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period a number of securities that does not exceed the greater of either of the following:

•

1% of the then outstanding equity shares of the same class which, immediately after the Business Combination, will equal approximately 1,567,847 shares of Combined Company Common Stock and 147,499 Novus Warrants, assuming that no Public Shares are redeemed; or

•

the average weekly trading volume of Combined Company Common Stock of the same class or Novus Warrants, as applicable, during the four calendar weeks preceding the date on which notice of the sale is filed with the SEC.

Sales by affiliates of Novus under Rule 144 are also subject to certain requirements relating to manner of sale, notice and the availability of current public information about Novus.

Restrictions on the Use of Rule 144 by Shell Companies or Former Shell Companies

Rule 144 is not available for the resale of securities initially issued by shell companies (other than business combination related shell companies) or issuers that have been at any time previously a shell company. However, Rule 144 also includes an important exception to this prohibition if the following conditions are met:

•

the issuer of the securities that was formerly a shell company has ceased to be a shell company;

•

the issuer of the securities is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act;

•

the issuer of the securities has filed all Exchange Act reports and material required to be filed, as applicable, during the preceding 12 months (or such shorter period that the issuer was required to file such reports and materials), other than Form 8-K reports; and

•

at least one year has elapsed from the time that the issuer filed current Form 10 type information with the SEC, which is expected to be filed promptly after completion of the Business Combination, reflecting its status as an entity that is not a shell company.

As of the date of this proxy statement/prospectus, there are 28,750,000 shares of Novus Common Stock, and 7,187,500 shares of Novus Class B Common Stock outstanding. Of these shares, the 28,750,000 shares sold in the IPO are freely tradable without restriction or further registration under the Securities Act, except for any shares purchased by one of our affiliates within the meaning of Rule 144 under the Securities Act. All of the remaining 7,187,500 shares owned collectively by the Founders are restricted securities under Rule 144, in that they were issued in private transactions not involving a public offering.

As of the date of this proxy statement/prospectus, there are a total of 14,749,999 Novus Warrants outstanding. Each warrant is exercisable for one share of Novus Common Stock, in accordance with the terms of the warrant agreement governing the Novus Warrants. 9,583,333 of these Novus Warrants are Public Warrants and are freely tradable, except for any warrants purchased by one of our affiliates within the meaning of Rule 144 under the Securities Act. In addition, we will be obligated to maintain an effective registration statement under the Securities Act covering the 9,583,333 shares of Novus Common Stock that may be issued upon the exercise of the public Novus Warrants.

TABLE OF CONTENTS

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information regarding (i) the actual beneficial ownership of Novus Common Stock as of the Record Date (the “Ownership Date”), which is prior to the consummation of the Business Combination (pre-Business Combination) and PIPE Financing and (ii) expected beneficial ownership of Combined Company Common Stock immediately following the Closing (post-Business Combination) and PIPE Financing, assuming that no Public Shares are redeemed, and alternatively that the maximum number of Public Shares (26,838,263 shares) are redeemed, by:

•

each person who is, or is expected to be, the beneficial owner of more than 5% of issued and outstanding shares of Novus Common Stock or of Combined Company Common Stock;

•

each of our current executive officers and directors;

•

each person who will become an executive officer or director of the Combined Company post-Business Combination; and

•

all executive officers and directors of Novus as a group pre-Business Combination and all executive officers and directors of the Combined Company post-Business Combination.

The following table also assumes that no Earn Out Shares are issued.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days. In computing the number of shares of common stock beneficially owned by a person or entity and the percentage ownership of that person or entity, we deemed to be outstanding all shares of common stock subject to options, warrants and restricted stock units held by that person or entity that are currently exercisable, or exercisable or would vest based on time-based vesting conditions within 60 days of the Ownership Date, assuming that the liquidity-event vesting conditions had been satisfied as of such date. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person or entity

Unless otherwise indicated and subject to applicable community property laws and other similar laws, we believe that all persons named in the table below have sole voting and investment power with respect to all shares of voting common stock beneficially owned by them.

The beneficial ownership of shares of Novus Common Stock pre-Business Combination is based on 35,937,500 shares of Novus Common stock (consisting of 28,750,000 shares of Novus Common Stock and 7,187,500 Founder Shares) issued and outstanding as of the Ownership Date.

The expected beneficial ownership of shares of the Combined Company Common Stock post-Business Combination and PIPE Financing assumes:

•

no exercise of the 9,583,333 Public Warrants or the 5,166,666 Private Placement Warrants that will remain outstanding post-Business Combination and that may be exercised at a later date;

•

forfeiture of 718,750 Founder Shares upon the Closing;

•

the issuance of approximately 15,000,000 shares of Novus Common Stock to the PIPE Subscribers;

•

that 106,566,033 shares of Combined Company Common Stock are issued to Energy Vault’s stockholders; and

•

that no Earn Out Shares are issued.

The expected beneficial ownership of shares of Combined Company Common Stock post-Business Combination Assuming No Redemption in the table below has been determined based upon the following assumptions: (i) no Public Stockholders exercise their redemption rights and (ii) that there are 156,784,788 shares of Combined Company Common Stock outstanding.

The expected beneficial ownership of shares of Combined Company Common Stock post-Business Combination Assuming Maximum Redemption in the table below has been determined based upon the

248

TABLE OF CONTENTS

following assumptions: (i) that 26,838,263 Public Shares are redeemed for an aggregate payment of approximately $268.4 million (based on the estimated per share redemption price of approximately $10.00 per share based on the fair value of marketable securities held in the Trust Account as of the Record Date of approximately $287.5 million) from the Trust Account, (ii) that 3,953,125 shares by the Novus Initial Stockholders and NCCII are forfeited, (iii) that there are 126,712,150 shares of Combined Company Common Stock outstanding, and (iii) that none of the relevant beneficial owners purchase shares of Novus Common Stock in the open market. Such calculations also do not account for Earn Out Shares.

ADDITIONAL INFORMATION

Submission of Future Stockholder Proposals

Novus’s board of directors is aware of no other matter that may be brought before the special meeting. Under Delaware law, only business that is specified in the notice of special meeting to stockholders may be transacted at the special meeting.

Novus does not expect to hold a 2021 annual meeting of stockholders because it will not be a separate public company if the Business Combination is completed. Alternatively, if Novus does not consummate an initial business combination by February 8, 2023 or obtain the approval of Novus’s stockholders to extend the deadline for Novus to consummate an initial business combination, Novus is required to begin the dissolution process provided for in the Existing Certificate of Incorporation. Novus will liquidate as soon as practicable following such dissolution and will conduct no annual meetings thereafter.

Legal Matters

The validity of the shares of Novus Common Stock to be issued in connection with the Business Combination will be passed upon by Blank Rome LLP.

HOUSEHOLDING INFORMATION

Report of Independent Registered Public Accounting Firm

Shareholders and Board of Directors
Energy Vault, Inc.
Westlake Village, CA 91361

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Energy Vault, Inc. (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of operations and comprehensive loss, convertible preferred stock and stockholders’ deficit, and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2020.

ORGANIZATION AND DESCRIPTION OF BUSINESS

Energy Vault, Inc. (the “Company”) was incorporated in the state of Delaware in October 2017 and is headquartered in Los Angeles, California. The Company is engaged in the design and development of gravity and kinetic energy based, long-duration energy storage solutions that will enable deployment of clean and renewable energy and sustainable electricity. The Company is developing a full-scale commercial demonstration unit (the “Prototype”) located in Arbedo-Castione Switzerland. In July 2020, the Prototype achieved mechanical completion and was connected to the Swiss national electricity grid.

The Company has a wholly owned subsidiary, Energy Vault SA, which was formed in December 2017 in Lugano Switzerland to build the Prototype and operate as the Company’s European headquarters.

Since inception, the Company has been primarily involved in research and development activities. The Company devotes substantially all its efforts to product research and development, initial market development and raising capital. The Company is subject to a number of risks similar to those of other early-stage companies, including dependence on key individuals, the need for development of commercially viable products, and the need to obtain adequate additional financing to fund the development of its products and technology.

Basis of Presentation and Liquidity

The consolidated financial statements are prepared on a going concern basis that contemplates the realization of assets and extinguishment of liabilities in the normal course of business. The Company has not yet generated revenues from its principal operations and has incurred net operating losses and negative cash flows from operations since inception. As of December 31, 2020, and 2019, the Company had an accumulated deficit of $37.6 million and $13.5 million, respectively. Management expects to incur additional losses in the future to conduct research and development and will use cash to continue to invest in the development of the Prototype or additional prototypes. To date, the Company’s principal source of liquidity has been net proceeds received from the issuance of preferred stock and convertible debt. The Company will need to raise additional capital to fully implement its business plan. During August and September 2021, the Company closed a private placement with large institutional investors and existing stockholders consisting of the sale of 2,182,515 shares of the Company’s Series C Preferred Stock amounting to $107 million, at a price of $49.0258 per share. Management expects to use the proceeds from the private placement to continue its research efforts and to finance the ongoing operations of the Company. The Company is also seeking to access the capital markets by entering into a definitive business combination agreement dated September 8, 2021 with Novus Capital Corporation II, a Special Purpose Acquisition Company (“SPAC”). The business combination is expected to close by the latter half of 2021, subject to approval from Novus and the Company’s shareholders. Management believes its plans and additional funding raised, alleviates any substantial doubt about the Company’s ability to continue as a going concern.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Use of Estimates

The preparation of the consolidated financial statements, in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company evaluates its assumptions on an ongoing basis. The Company’s management believes that the estimates, judgment, and assumptions used are reasonable based upon information available at the time they are made. Significant estimates made by management include, among others, valuation of inventory pension obligation, fair value of financial instruments including embedded derivatives, stock-based compensation, valuation of deferred income tax assets, and the useful life of long-lived assets. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of expenses during the reporting periods. Actual results could differ from those estimates.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash. Risks associated with cash are mitigated by banking with creditworthy institutions. Such balances with any one institution may, at times, be in excess of federally insured amounts (currently $250,000 per depositor). The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk due to its accounts being held with large, well-known financial institutions.

Other Risk and Uncertainties

The Company is subject to a number of risks similar to other early-stage clean energy companies, including, but not limited to, the need to obtain sufficient funding to support the significant capital spending required to develop the Prototype, competitors developing new technological innovations, the need to successfully commercialize and gain market acceptance of the Company’s products, and protection of proprietary technology, among others. These risks could be further complicated by the ongoing COVID-19 pandemic described below.

The spread of the COVID-19 virus during the quarter ended March 31, 2020 has caused an economic downturn on a global scale, as well as significant volatility in the financial markets. In March 2020, the World Health Organization declared the spread of the COVID-19 virus a pandemic. Government reactions to the public health crisis with mitigation measures have created significant uncertainties in the U.S. and global economies. The COVID-19 pandemic caused delays in the construction of the Prototype in Switzerland due to Government mandated temporary stay-at-home and quarantine orders; however, it did not significantly impact the Company’s other core operations such as research and development and fund raising. The extent to which the COVID-19 pandemic impacts the Company’s business, operations and financial results will depend on numerous evolving factors that management may not be able to accurately predict, and which may cause the actual results to differ from the estimates and assumptions that are required to be made in the preparation of financial statements according to U.S. GAAP.

Foreign Currency

Assets and liabilities denominated in a foreign currency are translated into U.S dollars using the exchange rates in effect at the balance sheet date. Revenue and expense accounts are translated at the average exchange rates during the periods. The impact of exchange rate fluctuations from translation of assets and liabilities is included in accumulated other comprehensive income, a component of stockholder’s equity. Gains and losses resulting from foreign currency transactions are included in other income (expense), net in the accompanying consolidated statements of operations.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Fair Value Measurements

ASC Topic 820, “Fair Value Measurement” (“ASC 820”), establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value as follows:

Level I — Inputs which include quoted prices in active markets for identical assets and liabilities.

Level II — Inputs other than Level I that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level III — Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Segment Reporting

The Company has a single operating and reportable business segment.

Cash Equivalents

Cash equivalents that are readily convertible to cash are stated at cost, which approximates fair value. The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. At December 31, 2020 and 2019, the Company maintained two money market accounts totaling $7,708,144 and $12,098,170, respectively.

Inventory, Long Term

The Company’s long-term inventory consists of costs incurred to construct the Protype which the Company intends to sell to a customer in the future.

Inventory is valued at the lower of cost, determined on a first in first out basis, or net realizable value. Provisions for excess and obsolete inventories are charged to cost of sales and are permanent reductions to the carrying value of inventories. There were no inventory reserves as of December 31, 2020 and 2019.

Property and Equipment, Net

Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. The useful lives of property and equipment are as follows:

	Brick Machines			6 years
	Vehicles			4 years
	Office equipment			7 years

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
(continued)

	Computer equipment			3 years
	Leasehold improvements			Shorter of remaining lease-term or estimated life of the assets

Maintenance and repairs are charged to expense as incurred. When assets are retired or sold, the cost and related accumulated depreciation are removed from the consolidated balance sheet and any resulting gain or loss is reflected in operating expenses in the period realized.

Impairment of Long-Lived Assets

The Company reviews long-lived assets, primarily comprised of property and equipment, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparison of the carrying amount to the future net cash flows which the assets are expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the projected undiscounted future net cash flows arising from the asset. In 2020, the Company reported an impairment of leasehold improvements of $27,696 related to architecture design fee of an office location; the Company incurred the cost before the lease negotiation was terminated. There were no such impairments of long‑lived assets for 2019.

Research and Development Expenses

Research and development costs are expensed as incurred. Research and development costs consist of salaries and other personnel related expenses, engineering expenses, product development costs and facility costs.

Derivative Instruments

A derivative is an instrument whose value is “derived” from an underlying instrument or index such as a future, forward, swap, option contract, or other financial instrument with similar characteristics, including certain derivative instruments embedded in other contracts (“embedded derivatives”) and for hedging activities. As a matter of policy, the Company does not invest in financial derivatives or engage in hedging transactions. However, the Company has entered into complex financing transactions that involve financial instruments containing certain features that have resulted in the instruments being deemed derivatives or containing embedded derivatives. Derivatives and embedded derivatives, if applicable, are measured at fair value using Black-Scholes or Monte Carlo pricing model and marked to market and changes in fair value are reflected on the consolidated statement of operations as other (income) expense at each reporting period. However, such new and/or complex instruments may have immature or limited markets. As a result, the pricing models used for valuation of derivatives often incorporate significant estimates and assumptions, which may impact the level of precision in the financial statements. Furthermore, depending on the terms of a derivative or embedded derivative, the valuation of derivatives may be removed from the financial statements upon conversion of the underlying instrument into some other security.

Defined Benefit Pension Obligation

The Company’s wholly owned subsidiary in Switzerland has a defined benefit pension obligation covering retirement and other long-term benefits of the local employees. The plan is a statutory requirement in accordance with local regulations, had a projected benefit obligation of $2,425,078 and $1,552,316, respectively, plan assets with a fair value of $1,591,671 and $983,942, respectively, and an underfunded net benefit obligation of $833,487 and $568,389 at December 31, 2020 and 2019, respectively. The net periodic cost of the plan totaled $101,356 and $48,002 during the years ended December 31, 2020 and 2019, respectively.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Revenue Recognition

On January 1, 2018, the Company adopted ASC Topic 606, “Revenue from Contracts with Customers.”

The Company recognizes revenue when control of promised goods or services are transferred to a customer in an amount that reflects the consideration expected to be received for those goods or services. Revenue is recognized when or as the performance obligation has been satisfied and control of the product has transferred to the customer. In evaluating the timing of the transfer of control of products to customers, the Company considers several indicators, including significant risks and rewards of products, the right to payment, and the legal title of the products. Deferred revenue represents billings or payments received in advance of services performed.

Income Taxes

The Company accounts for income taxes in accordance with ASC Topic 740, “Income Taxes” (“ASC 740”). ASC 740 prescribes the use of the liability method, whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates that will be in effect when the differences are expected to reverse.

Deferred income tax balances reflect the effects of temporary differences between the carrying amounts of assets and liabilities and their tax bases and are stated at enacted tax rates expected to be in effect when taxes are actually paid or recovered. Deferred tax assets are evaluated for future realization and reduced by a valuation allowance to the extent the Company believes they will not be realized.

Comprehensive Loss

Assets and liabilities of the Switzerland subsidiary that operates in a local currency environment, where the foreign local currency is the functional currency, are translated into U.S. dollars at the exchange rates in effect at the balance sheet date, with the resulting translation adjustments recorded to a separate component of accumulated other comprehensive income (loss). Income and expense accounts are translated at the average exchange rates during the year. For the year ended December 31, 2020 and 2019, foreign currency translation loss was $1,250,390 and $174,246, respectively.

Transactions in currencies other than each entity’s functional currency are recorded using the exchange rates prevailing at the dates of the transactions. Exchange adjustments arising from the difference between the date a transaction was recognized and the date in which it was settled are recognized in the accompanying consolidated statements of operations and comprehensive loss as other income (expense).

Other comprehensive loss is reflected in the consolidated statements of stockholders’ equity (deficit) and is separately identified on the consolidated statement of operations and comprehensive loss. It consists of cumulative foreign currency translation adjustments, net of taxes, and actuarial loss on pensions.

Net Loss Per Share of Common Stock

Basic net loss per share of common stock is calculated by dividing net loss by the weighted average number of common shares outstanding for the applicable period. Diluted net loss is computed based on the weighted average number of common shares outstanding increased by the number of additional shares that would have been outstanding had the potentially dilutive common shares been issued, including any dilutive effect from convertible preferred stock, outstanding stock options or unvested restricted common stock, and reduced by the number of shares the Company could have repurchased with the proceeds from the issuance of the potentially dilutive shares. Potentially dilutive instruments are excluded from the per share calculation because the Company is in a net loss position and they would therefore be anti-dilutive.

F-11

TABLE OF CONTENTS

ENERGY VAULT, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2020 and 2019

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

The Company follows the two-class method when computing net loss per share for periods when issued shares that meet the definition of participating securities are outstanding. The two-class method calls for the calculation of net loss per share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income available to common stockholders to be allocated between common and participating securities based upon their respective rights to received dividends as if all income for the period had been distributed. Net losses are not allocated to the Company’s preferred stockholders as they do not have an obligation to share in the Company’s net losses.

Stock-Based Compensation

The Company accounts for stock-based compensation arrangements in accordance with ASC Topic 718, “Stock Compensation”. The Company measures its stock option awards based on the estimated fair values of the awards as of the grant date using the Black-Scholes option-pricing model. Compensation expense is recognized over the requisite service period (usually the vesting period) on a straight-line basis and is adjusted for actual forfeitures of unvested awards as they occur.

On January 1, 2018, the Company adopted Accounting Standard Update (“ASU”) No. 2018-07 that expands the scope of existing share-based compensation guidance for employees. The standard includes share-based payment transactions for acquiring goods and services from nonemployees, whereby share-based payments to nonemployees are measured and recorded at the fair value of the equity instruments that an entity is obligated to issue on the grant date.

Leases

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, “Leases” (Topic 842). This new standard introduces a new lease model that requires the recognition of lease assets and lease liabilities on the balance sheet and the disclosure of key information about leasing arrangements. The recognition, presentation, and measurement of lease related items in the financial statements will depend on whether the lease is classified as a finance or operating lease. In addition, the new guidance requires disclosures regarding the amount, timing and uncertainty of cash flows arising from leases. The new lease standard applied to lessor accounting remains largely unchanged from legacy U.S. GAAP; however, the new standard does contain some targeted improvements to align with the new revenue recognition guidance, issued pursuant to ASU No. 2014-09 (as amended).

The Company adopted the new standard with an effective date of January 1, 2018. The new standard provides for a number of optional practical expedients. The Company has elected the practical expedient (including for those leases for which the Company is a lessee) to use hindsight in determining the lease term (that is, when considering lessee options to extend or terminate the lease or to purchase the underlying asset) and in assessing impairment of the Company’s right of use (ROU) assets.

The new lease standard provides several optional policy elections for an entity’s ongoing accounting. Generally, the Company has decided not to elect the policy to not separate lease and non-lease components in arrangements whereby the Company is the lessee. The Company has elected to exclude short-term leases (with original lease terms of twelve months or less) from the balance sheet. However, the Company has elected to include all expenses related to leases with a term of one month or less (i.e., month-to-month or evergreen leases) in the short-term lease expense disclosure amount in the footnote table.

Recent Accounting Pronouncements Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. ASU 2016-13 amends the impairment model to

F-12

TABLE OF CONTENTS

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the more timely recognition of losses. The new accounting standard will be effective for the fiscal year beginning on January 1, 2023, including interim periods within that year. The Company does not expect that adoption of this standard will have a material impact on its consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes — Simplifying the Accounting for Income Taxes. The guidance removes exceptions to the general principles in Topic 740 for allocating tax expense between financial statement components, accounting basis differences stemming from an ownership change in foreign investments and interim period income tax accounting for year-to-date losses that exceed projected losses. The guidance becomes effective for annual reporting periods beginning after December 15, 2020 and interim periods within those fiscal years with early adoption permitted. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

In August 2020, FASB issued ASU No. 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”). ASU 2020-06 simplifies the accounting for convertible instruments. In addition to eliminating certain accounting models, this ASU includes improvements to the disclosures for convertible instruments and earnings-per-share (EPS) guidance and amends the guidance for the derivatives scope exception for contracts in an entity’s own equity. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021. The Company is still evaluating the effects that the requirements of this ASU will have on its consolidated financial statements.

FAIR VALUE MEASUREMENTS

Carrying amounts of certain financial instruments, including cash, accounts payable, and accrued liabilities approximate their fair value due to their relatively short maturities and market interest rates, if applicable.

Assets and liabilities measured at fair value on a recurring basis as of December 31, 2019 were as follows:

In December 2020, in connection with issuance of Series B-1 preferred stock, the terms of Tranche 2 in the Series B preferred stock were amended to be identical to the B-1 preferred stock. This resulted in the fair value of the derivative liability associated with the Series B preferred stock right (Note 11) being reduced to zero value. In January 2021, Tranche 3 in the Series B preferred stock expired without exercise; the Company recorded a change in fair value to reduce to zero the value of the derivative asset associated with Tranche 3 as of December 31, 2020 (Note 15).

The fair value of the preferred stock Tranche rights was determined using a Monte Carlo simulation model (Note 11) and the fair value of the embedded derivative was determined using Black-Scholes analysis (Note 9). There were no changes in valuation techniques or transfers between the fair value measurement levels during the years ended December 31, 2020 or 2019.

The following table provides a reconciliation of all assets and liabilities measured at fair value using Level 3 significant unobservable inputs:

	Preferred Stock Tranche Asset			Preferred Stock Tranche Liability			Embedded Derivative Liability

The Company also recorded certain financial instruments at fair value on a non-recurring basis. During the year ended December 31, 2020, the Series B-1 preferred stock was recorded at its estimated fair value of $7,902,908 upon conversion of the Series B-1 convertible notes payable and $7,779,985 in cash proceeds (Note 11). During the year ended December 31, 2019, the Series A-1 preferred stock was recorded at its estimated fair value of $3,075,831 upon conversion the Series A-1 convertible notes payable (Note 11); and the Series A-2 preferred stock was recorded at its estimated fair value of $3,554,714 upon conversion of $2,504,716 in Series A-2 convertible notes payable and $1,049,998 in cash proceeds (Note 11); and the Series B preferred stock was recorded at its estimated fair value of $25,000,000 and the detachable Tranche Rights were bifurcated from the host instrument and valued separately at $11,516,593 (Note 11).

CONVERTIBLE NOTES PAYABLE

At December 31, 2020 and 2019, the Company had no outstanding convertible notes payable balance.

2020 Issuances

In September and November 2020, the Company issued Series B-1 convertible notes payable for aggregate cash proceeds of $7,777,500. Interest accrued at 8% per annum and the note matured 12 months after issuance when principal and accrued interest were due. The B-1 notes were convertible on or before maturity into equity securities issued and sold at the close of the Company’s next equity financing (the “B-1 Next Equity Securities”) yielding gross cash proceeds to the Company of at least $10,000,000. The conversion price is equal to the lesser of (A) the lowest price per share of the B-1 Next Equity Securities sold in the Next Equity Financing and (B) the price per equity security equal to $180 million, divided by the full diluted capital of the Company. The B-1 notes were converted to Series B-1 preferred stock in December 2020, see further discussion below in Note 11.

In December 2020, the holders of the B-1 convertible notes payable consented to conversion of the notes to B-1 preferred stock below the $10,000,000 cash proceeds threshold. Because the convertible notes payable were not settled under the original terms, the Company considered the carrying value of the notes payable and accrued interest compared to the fair value of B-1 preferred stock issued in December 2020 and concluded there was no material difference between the values. Therefore, the Company did not record any gain or loss on the modification.

2019 Issuances

In March 2019, the Company issued Series A-2 convertible notes payable for aggregate cash proceeds of $2,500,000. Interest accrued at 2.55% per annum and matured 18 months after issuance when principal and accrued interest were due. The A-2 notes were convertible on or before maturity into equity securities issued and sold at the close of the Company’s next equity financing (the “Next Equity Securities”) yielding gross cash proceeds to the Company of at least $1,000,000. The conversion price is equal to the lesser of (A) 100% of the lowest price per share of the Next Equity Securities sold and (B) the price per equity security equal to $37.5 million, divided by the fully diluted capital of the Company. The A-2 notes were converted to Series A-2 preferred stock in May 2019, see further discussion below.

2018 Issuances

In December 2018, the Company issued Series A-1 convertible notes payable for aggregate cash proceeds of $3,050,000. Interest accrued at 2.76% per annum and matured 18 months after issuance when principal and accrued interest were due. The A-1 notes were convertible on or before maturity into equity securities issued and sold at the close of the Company’s next equity financing (the “Next Equity Securities”) yielding gross cash proceeds to the Company of at least $1,000,000. The conversion price is equal to the

lesser of (A) 80% of the lowest price per share of the Next Equity Securities sold and (B) the price per equity security equal to $20 million, divided by the fully diluted capital of the Company. The A-1 notes were converted to Series A-1 preferred stock in May 2019, see further discussion below.

Change of Control Provision

For each of the Company’s convertible notes payable described above, the notes required that in the event of a change of control, then, immediately prior to such change of control, in lieu of the principal and interest that would otherwise be payable on the Maturity Date, the Company would pay the holder an aggregate amount equal to the greater of (A) all outstanding principal and accrued and unpaid interest due under the Note, or (B) the amount the Holder would have received if the Note were converted in accordance with the conversion terms.

Embedded Derivative

The Company analyzed the terms of its convertible notes payable agreements for embedded features that may require bifurcation from the debt host. The Company concluded that, pursuant to ASC Topic 815, “Derivatives and Hedging”, the conversion option in the Series A-1 convertible notes payable includes an option to convert at 80% of the lowest price per share of the next equity securities sold by the Company is akin to a redemption feature and contains a substantial discount. Therefore, the redemption feature is required to be bifurcated and accounted for separately as an embedded derivative. The Company recorded the derivative liability at its estimated fair value of $370,000 on the date of issuance (December 24, 2018) with a corresponding discount to the debt. The Company remeasured the fair value of the derivative at December 31, 2018; there was no material change. The derivative was remeasured again in May 2019 at the time of conversion, and it was determined the value was zero. Accordingly, the Company recognized a gain on the change in fair value totaling $370,000. The debt discount was accreted through the conversion date and recorded as interest expense in the accompanying statements of operations and comprehensive loss. The Company measured the fair value of the embedded derivative at each measurement date using “With” and “Without” method based on the valuation of straight debt plus call option using the Black-Scholes analysis.

Beneficial Conversion Feature

A convertible financial instrument includes a beneficial conversion feature (BCF) if the effective conversion price is less than the company’s market price of common stock on the commitment date. The effective price paid for a common share is the amount allocated to the convertible instrument, divided by the number of shares the holder is entitled to upon conversion. The commitment date is the date that the contract is binding on both parties and usually legally enforceable. At this date, the agreement specifies all significant terms and includes a disincentive for nonperformance that is sufficiently large to make performance probable. At the time of the issuance of the A-1 convertible notes payable, the conversion price was contingent upon the price paid in the next equity financing.

The Company evaluated the conversion features in its convertible notes and determined that the conversion feature in the A-1 convertible notes payable had a BCF. The Company evaluated the BCF and determined that there was not a commitment date upon the issuance of the A-1 convertible notes payable because the conversion price was contingent upon the price paid in a future financing and the terms of such financing were not known. Therefore, the BCF was measured and recorded based on its intrinsic value at the date of conversion of the A-1 convertible notes payable to the A-1 preferred stock. The value of the BCF totaled $788,584 and was recorded as a charge to interest expense in the accompanying statement of operations and comprehensive loss for the year ended December 31, 2019.

Paycheck Protection Program

In May 2020, the Company received loan proceeds in the amount of $220,020 under the Paycheck Protection Program (“PPP”) which was established as part of the Coronavirus Aid, Relief and Economic Security (“CARES”) Act and is administered through the Small Business Administration (“SBA”). The PPP provides loans to qualifying businesses in amounts up to 2.5 times their average monthly payroll expenses and was designed to provide a direct financial incentive for qualifying businesses to keep their workforce employed during the Coronavirus crisis. PPP loans are uncollateralized and guaranteed by the SBA and are forgivable after a “covered period” (eight or twenty-four weeks) as long as the borrower maintains its payroll levels and uses the loan proceeds for eligible expenses, including payroll, benefits, mortgage interest, rent, and utilities. The forgiveness amount will be reduced if the borrower terminates employees or reduces salaries and wages more than 25% during the covered period. Any unforgiven portion is payable over 2 years if issued before, or 5 years if issued after, June 5, 2020 at an interest rate of 1% with payments deferred until the SBA remits the borrower’s loan forgiveness amount to the lender, or, if the borrower does not apply for forgiveness, ten months after the end of the covered period. PPP loan terms provide for customary events of default, including payment defaults, breaches of representations and warranties, and insolvency events and may be accelerated upon the occurrence of one or more of these events of default. Additionally, PPP loan terms do not include prepayment penalties.

The Company’s management believes the Company met the PPP’s loan forgiveness requirements, and therefore intends to apply for forgiveness during 2021. When and if legal release by the SBA is received, the Company will record the amount forgiven as forgiveness income within the other income section of its statement of operations. If any portion of the Company’s PPP loan is not forgiven, the Company will be required to repay that portion, plus interest, over 2 years in monthly installments with the repayment term beginning at the time that the SBA remits the amount forgiven to the Company’s lender.

The SBA reserves the right to audit any PPP loan, regardless of size. These audits may occur after forgiveness has been granted. In accordance with the CARES Act, all borrowers are required to maintain their PPP loan documentation for six years after the PPP loan was forgiven or repaid in full and to provide that documentation to the SBA upon request.

Swiss Government COVID-19 Relief Loan

In March 2020, the Company’s subsidiary received loan proceeds in the amount of $518,645 under the Swiss Government COVID-19 Financial Assistance Program. The note bears no interest and matures 60 months from the date of issuance at which point the unpaid balance of the note is due in full. The Swiss Government COVID-19 Financial Assistance Program provides loans to qualifying business in amounts based on annual turnover and was designed to provide a direct financial incentive for qualifying businesses to keep their workforce employed during the Coronavirus crisis. These loans are uncollateralized and guaranteed by the Canton Government.

STOCKHOLDERS’ EQUITY (continued)

Dividends

The holders of each class of preferred stock are entitled to receive noncumulative dividends at 8% per annum, if and when declared by the board of directors. The board of directors did not declare any dividends during the years ended December 31, 2020 and 2019.

The preferred stock also includes participation rights that states that no dividend shall be paid on the Common Stock in any year, other than dividends payable solely in capital stock, until all dividends for such year have been declared and paid on the Preferred Stock, and no dividends on the Common Stock shall be paid unless the amount of such dividend on the Common Stock is also paid on the Preferred Stock on an as converted to Common Stock basis.

Conversion

Each class of preferred stock is convertible to common stock at the option of the holder at the conversion price (as defined in the articles of incorporation) which is initially equal to the original issuance price of each of the preferred stock issuances. The preferred stock is automatically converted to common stock upon the earlier of a) a firm commitment underwritten initial public offering to an effective registration statement and sale of common stock to the public of not less than $9.4728 per share (minimum price per share does not apply to Series FR, Seed 1 and Seed 2 preferred stock) with gross proceeds not less than $30 million, or b) by written consent of the holders of a majority of the then outstanding shares of preferred stock voting as single class on an as-converted to common stock basis, with the holders of the Series A, Seed 2, Seed 1, and Series FR preferred stock voting as a separate class on an as-converted basis, and the holders of the Series B voting as a separate class on an as-converted basis, and the holders of the Series B-1 voting as a separate class on an as-converted basis.

The conversion price is subject to adjustment for stock splits and stock dividends, reorganization, reclassifications, or similar events and shall be adjusted proportionately. The conversion price is also adjusted for certain dilutive issuances of common stock or securities exercisable or convertible into common stock at a price below the conversion price in effect at the time (price protection or ratchet feature). The adjustment to the conversion price is determined by multiplying the conversion price by a fraction calculated as the diluted shares pre-issuance at the conversion price divided by the common stock pre-issuance plus the additional stock issued (partial ratchet).

Liquidation

Upon liquidation, dissolution, or winding up of the Company, the holders of Series B and Series B-1 preferred stock are entitled to, in preference to the holders of each of the other classes of preferred stock, and to the common stockholder, an amount equal to the original issuance price plus declared but unpaid dividends. After payment in full to the holders of Series B and B-1 preferred stock, and prior to any distribution to the common stockholders, each of the other classes of preferred stock are entitled to receive an amount equal to the original issue price plus declared and unpaid dividends on such shares, payable on a pari passu basis among the Series.

A liquidation, dissolution, or winding up of the Company shall be deemed to have occurred upon completion of any transaction or event that results in a change of control as defined in the articles of incorporation (a “Deemed Liquidation Event”). Upon a Deemed Liquidation Event, the preferred stock becomes redeemable at the option of the holder and the Company is required to provide written notice to the holders of the preferred stock within 90 days of such an event informing them of their right to redeem the preferred stock. For purposes of determining the amount each holder of preferred stock is entitled to receive upon a Deemed Liquidation Event, each class of preferred stock is deemed to have automatically converted their shares into common stock at the as converted value (even if not elected by the holder) immediately

prior to such a Deemed Liquidation Event, if the value is greater than the amount that would have been distributed to the holder of the preferred stock if it were not converted.

Voting

Each share of preferred stock is entitled to the number of votes equal to the number of shares of common stock into which the shares of preferred stock so held could be converted at the record date.

Series B Tranche Rights

The Series B preferred stock purchase agreement includes terms that obligated the investors to purchase, and the Company to sell, two subsequent rounds of Series B preferred stock in tranche closings (the “Tranche Rights”), the first of which is for proceeds totaling $45,000,000 in exchange for shares in the capital of the Company resulting in the holding of 35.27% of the shares of the Company on a fully diluted basis (“Tranche 2”), and the second for proceeds totaling $40,000,000 in exchange for shares in the capital of the Company resulting in the holding of 37.82% of the shares of the Company on a fully diluted basis (“Tranche 3”). The terms of the Tranche 2 and Tranche 3 preferred shares shall be substantially identical to the Series B preferred stock except with respect to purchase price. The issuance of Tranche 2 and Tranche 3 is subject to and conditioned upon the successful deployment of the Prototype and the Company reaching certain commercial milestones as described in the stock purchase agreement. The deadline for completion of the Tranche requirements was 18 months from the closing date of Series B preferred stock purchase agreement or January 2021. In December 2020, in connection with issuance of Series B-1 preferred stock, the terms of Tranche 2 in the Series B preferred stock were amended to be identical to the B-1 preferred stock, and the deadline for the completion of certain milestones in the development of the Prototype was extended to June 30, 2021. In January 2021, the Tranche 3 deadline expired, and the Company has not entered into an agreement to extend the rights set forth therein (Note 15). The Tranche Rights were transferable by the investors, and separately exercisable.

The Company concluded that the Tranche Rights met the definition of a freestanding financial instrument, as the Tranche Rights were legally detachable and separately exercisable from the Series B preferred stock. Therefore, the Company allocated the net proceeds between the Tranche Rights and the Series B preferred stock. Since the Series B preferred stock was contingently redeemable upon the occurrence of a deemed liquidation event, the Tranche Rights were classified as an asset or liability under ASC Topic 480, “Distinguishing Liabilities from Equity”, and were initially recorded at fair value. The Tranche Rights were measured at fair value at each reporting period. Since the Tranche Rights were subject to fair value accounting, the Company allocated the proceeds to the Tranche Rights based on the fair value at the date of issuance with the remaining proceeds being allocated to the Series B preferred stock. The estimated fair value of the Tranche Rights was determined using a probability-weighted present value model that considered the probability of closing a tranche, the estimated future value of Series B preferred stock at each closing and the investment required at each closing. Future values were converted to present value using a discount rate appropriate for probability-adjusted cash flows.

Tranche 2 was initially recorded as a liability of $834,613 as the purchase price of the additional shares was less than the estimated value of the Series B preferred stock at the expected settlement date. Conversely, Tranche 3 was initially recorded as an asset of $12,351,206 as the purchase price of the additional shares was greater than the estimated price of the Series B preferred stock at the expected settlement date. Tranche 2 and Tranche 3 were remeasured at December 31, 2019 and the Company recorded a net gain on the change in fair value of derivatives totaling $406,407. Tranche 2 and Tranche 3 were remeasured at December 31, 2020 and the Company recorded a net loss on the change in fair value of derivatives totaling $11,923,000. The Company measured the fair value of the Tranche rights at each measuring date using the Monte Carlo simulation model adjusted for probability of future Tranche financing.

The Company did not issue any grants in 2020. During the year ended December 31, 2019 the estimated weighted-average grant-date fair value of options granted was $0.71 per share.

The estimated fair value of employee stock options granted during the year ended December 31, 2019 was calculated using the Black-Scholes option-pricing model using the following range of assumptions:

	Expected volatility					80%
	Risk free interest rate					2.50%
	Expected dividend yield					—
	Expected term (years)					6.25

The methods used to determine the inputs to the estimated fair value of option awards under the Black-Scholes option-pricing model is described below; the inputs are subjective and generally require significant judgment to determine.

Expected Term — The Company’s expected term represents the period that the Company’s options granted are expected to be outstanding and is determined based on the simplified method, as the Company does not have historical exercise data.

Expected Volatility — Since the Company is privately held and does not have any trading history for its common stock, the expected volatility was estimated based on the average volatility for comparable publicly traded companies over a period equal to the expected term of the stock option grants.

STOCK-BASED COMPENSATION (continued)

Risk-Free Interest Rate — The risk-free interest rate is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected term of option.

Expected Dividend — The Company has never paid dividends on its common stock and has no plans to pay dividends on its common stock. Therefore, the Company used an expected dividend yield of zero.

The fair value of the Company’s shares of common stock underlying its stock options has historically been determined by the Company’s Board of Directors. Because there has been no public market for the Company’s common stock, the Company’s Board of Directors has determined fair value of the common stock at the time of grant of the option by considering a number of objective and subjective factors including important developments in the Company’s operations, valuations performed by an independent third party, sales of convertible preferred stock, actual operating results and financial performance, the conditions in the energy storage industry and the economy in general, the stock price performance and volatility of comparable public companies, and the lack of liquidity of the Company’s common stock, among other factors.

Unvested Common Stock

The Company has certain common stocks that are subject to repurchase at the election of the Company. These repurchase rights expire over time and therefore are accounted for as unvested common stock. The following table summarizes information about outstanding unvested stock activities:

	Unvested Common Stock
Balances outstanding at December 31, 2018		1,184,550
New grants or issues		259,810
Common stock vested		(526,184)
Balances outstanding at December 31, 2019		918,176
Common stock vested		(467,753)
Balances outstanding at December 31, 2020		450,424

Compensation Expense

Total stock-based compensation expense recognized for both employees and non-employees was as follows:

As of December 31, 2020, total unamortized stock-based compensation expense related to unvested awards that are expected to vest was $36,986. The weighted-average period over which such stock-based compensation expense will be recognized is approximately 1.5 years.

Total deferred tax assets, net of valuation allowance		$	—		$	—

In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Based upon the analysis of federal and state deferred tax balances, future tax projections and availability of taxable income in the carryback period, the Company established a 100% valuation allowance due to the uncertainty of realizing future tax benefits from its net operating loss carryforwards and other deferred tax assets.

At December 31, 2020, the Company had net operating loss carryforwards of $7,509,498 for federal, $10,182,449 for state, and $15,952,683 for foreign income tax purposes available to offset future taxable income. At December 31, 2019, the Company had net operating loss carryforwards of $4,574,507 for federal, $10,115,459 for state, and $7,391,095 for foreign income tax purposes available to offset future taxable income. The net operating loss carryforwards will begin to expire, if unutilized, beginning in 2038. Based upon the analysis of federal and state deferred tax balances, future tax projections, and availability of taxable income in the carryback period, the Company recorded a valuation allowance against the federal, state, and international deferred tax asset of $5,114,507 and $2,606,724 for the years ended December 31, 2020 and 2019, respectively.

The Company’s ability to utilize the net operating losses and tax credit carryforwards are subject to limitations in the event of an ownership change as defined in Section 382 of the Internal Revenue Code (“IRC”) of 1986, as amended, and similar state law. In general, an ownership change occurs if the aggregate stock ownership of certain stockholders increases by more than 50 percentage points over such stockholders’ lowest percentage ownership during the testing period. The Company has considered Section 382 of the IRC and concluded that a change of ownership may have occurred in May or July of 2019. The Company believes it would not result in a limitation amount that would cause the 2019 pre-change net operating loss carryforwards to expire unused.

At December 31, 2020, the Company had federal and state research tax credit carryforwards of $88,282 and $50,759, respectively.

At December 31, 2020 and 2019, the Company recorded $881,796, and $867,892, respectively, of unrecognized tax benefits. The Company’s policy is to recognize interest and penalties related to uncertain

tax positions, if any, in the income tax provision. During the years ended December 31, 2020 and 2019, the Company recognized no interest and penalties related to uncertain tax positions.

The following table summarizes the activity related to the Company’s unrecognized tax benefits during the year ended December 31, 2019 and 2020:

	Unrecognized Tax Benefits
Balance as of December 31, 2019		$	867,892
Increase related to prior year tax positions			—

Balance as of December 31, 2020		$	881,796
Interest balance as of December 31, 2020			—
Penalties as of December 31, 2020			—

The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate as of December 31, 2020 and December 31, 2019 is $0, due to the valuation allowance that would otherwise be recorded on the deferred tax asset associated with the recognized position.

LEASES

The Company has operating leases for its corporate offices and field offices. The Company recognized a right of use asset and lease liability for operating leases based on the net present value of future minimum lease payments. Lease expense is recognized on a straight-line basis over the non-cancelable lease term and renewal periods that are considered reasonably certain.

The Company has finance leases for vehicles. The Company recognized a right of use asset and lease liability for finance leases based on the net present value of future minimum lease payments. Lease expense for the Company’s finance leases is comprised of the amortization of the right of use asset and interest expense recognized based on the effective interest method.

The Company has elected to use hindsight in determining the lease term (that is, when considering lessee options to extend or terminate the lease or to purchase the underlying asset) and in assessing impairment of the entity’s right of use assets. Accordingly, management’s decisions regarding lease renewals that are reasonably certain to be exercised have been incorporated as part of the lease term in right of use asset and lease liability calculations. To support these determinations, the Company evaluated each active lease at transition that included a renewal option (or options) to assess whether or not the future renewal options were reasonably certain to be exercised. The periods related to any renewal options deemed not reasonably certain to be exercised were excluded from the lease term for the right of use asset and lease liability calculations.

LEASES (continued)

Future maturities of operating and finance leases as of December 31, 2020 are as follows:

	Operating Leases			Finance Leases
2021		$	450,500		$	31,608
2022			243,436			39,971

Less: interest			(153,250)			(2,536)
Total lease liability		$	1,270,259		$	93,285

The Company uses the rate implicit in the lease, when available, to discount lease payments to present value; however, when the rate implicit in the lease is not available, the incremental borrowing rate is used, which is based on the estimated interest rate for collateralized borrowing over a similar term of the lease at commencement date. The Company used an incremental borrowing rate of 5.37% for the majority of its leases.

Lease Modifications

Westlake Village Office Lease

In May 2020, the Company received COVID-19 related four-month rent deferral for its operating leases for office space. The Company elected to utilize the FASB’s COVID-19 lease accounting relief provisions and chose to account for the concession as if no changes to the lease contract were made.

In September 2020, additional adjustments were agreed to by the lessor which resulted in the abatement of three months of rent and a change to the frequency of the lease payments from semi-annual to monthly. The Company determined that this second set of lease adjustments did substantially change the frequency and the amount of lease payments remaining to be paid through the remainder of the lease term; therefore, these lease adjustments did not qualify for the COVID-19 lease accounting relief provisions. The lease was modified under Topic 842 which required a remeasurement of the lease. The net adjustment to the right-of-use asset of $30,712 is reflected in the footnote table under right-of-use assets obtained in exchange for operating lease liabilities.

In December 2020, the Company received another four-month partial rent deferral under the terms amended in September as a result of a new official lockdown. As with the previous rent deferment, there was no material change to the total amount of the consideration in the lease and the Company elected to utilize the FASB’s COVID-19 lease accounting relief provisions for this deferment.

Arbedo-Castione Land Lease

In June 2020, the Company obtained additional rights to land and structures that were contiguous to its existing land lease. The increase in lease payments related to the lease modification was not commensurate with the standalone price for the additional right of use associated with the land and structures when compared to the original lease. Consequently, these adjustments to the terms of the lease were treated as a modification of the original lease. The net adjustment to the right-of-use asset of $237,516 is reflected in the footnote table under right-of-use assets obtained in exchange for operating lease liabilities.

ORGANIZATION AND DESCRIPTION OF BUSINESS

The Company has a wholly owned subsidiary, Energy Vault SA, which was formed in December 2017 in Lugano Switzerland to build the Prototype and operate as the Company’s European headquarters.

Merger with Novus Capital Corp II

On September 8, 2021, Novus Capital Corporation II (“Novus”) (NASDAQ:NXU), a special purpose acquisition company announced that it had entered into a definitive agreement for a business combination (“merger”) that would result in the Company becoming a wholly owned subsidiary of Novus. The merger is expected to complete in early 2022.

As of September 30, 2021, the Company has incurred and capitalized $1.2 million of merger related costs. The capitalized costs have been recorded in the balance sheet in other current assets. Out of the aggregate $1.2 million merger related costs, $0.5 million has been paid and $0.7 million is recorded within account payable.

Basis of Presentation and Liquidity

The Company’s consolidated financial statements are prepared on a going concern basis that contemplates the realization of assets and extinguishment of liabilities in the normal course of business. The Company has not yet generated revenues from its principal operations and has incurred net operating losses and negative cash flows from operations since inception. As of September 30, 2021, and December 31, 2020, the Company had an accumulated deficit of $56.2 million and $37.6 million, respectively. Management expects to incur additional losses in the future to conduct research and development and will use cash to continue to invest in the development of the Prototype or additional prototypes. To date, the Company’s principal source of liquidity has been net proceeds received from the issuance of preferred stock and convertible debt.

The Company will need to raise additional capital to fully implement its business plan. During August and September 2021, the Company closed a private placement with large institutional investors and existing stockholders consisting of the sale of 2,182,515 shares of the Company’s Series C Preferred Stock amounting to $107 million, at a price of $49.0258 per share. Management expects to use the proceeds from the private placement to continue its research efforts and to finance the ongoing operations of the Company. Management believes its plans and additional funding raised, alleviates any substantial doubt about the Company’s ability to continue as a going concern for at least the next twelve months.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

These unaudited Interim Condensed Consolidated Financial Statements include Energy Vault Inc. and its wholly owned subsidiary, Energy Vault S.A. All significant intercompany balances and transactions have been eliminated in consolidation.

Basis of Accounting

The accompanying unaudited Interim Condensed Consolidated Financial Statements have been prepared on an accrual basis of accounting in accordance with Generally Accepted Accounting Principles

in the United States (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. Accordingly, these unaudited Interim Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2020. The Condensed Balance Sheet as of December 31, 2020, included herein, was derived from the Consolidated Financial Statements of the Company as of that date.

These unaudited Interim Condensed Consolidated Financial Statements, in the opinion of management, reflect all adjustments necessary to present fairly the Company’s financial position as of September 30, 2021 and the Company’s results of operations and comprehensive loss, convertible preferred stock and stockholders’ deficit activities, and the cash flows for the nine months ended September 30, 2021 and 2020. The results for the nine months ended September 30, 2021 are not necessarily indicative of the results to be expected for the year ending December 31, 2021 or for any interim period or for any other future year.

The Company has reclassified $598,036 of prepayments in the consolidated financial statement as of and for the nine months ended September 30, 2021 to correct an immaterial classification error in inventory as of December 31, 2020. This reclassification did not have any effect on net loss or comprehensive loss for any year or interim period. See Note 5 for additional discussion of the reclassification of inventory balances to property and equipment.

Emerging Growth Company

Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised, and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard.

This may make comparison of the Company’s consolidated financial statement with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Other Risk and Uncertainties

The spread of the COVID-19 virus during the quarter ended March 31, 2020 had caused an economic downturn on a global scale, as well as significant volatility in the financial markets. During the previous year ended, i.e., in March 2020, the World Health Organization declared spread of the COVID-19 virus a pandemic. Government reactions to the public health crisis with mitigation measures had created significant uncertainties in the U.S. and global economies. The COVID-19 pandemic caused delays in the construction of the Prototype in Switzerland due to Government mandated temporary stay-at-home and quarantine orders; however, it did not significantly impact the Company’s other core operations such as research and development and fund raising. The extent to which the COVID-19 pandemic impacts the Company’s business, operations and financial results will depend on numerous evolving factors that management may not be

able to accurately predict, and which may cause the actual results to differ from the estimates and assumptions that are required to be made in the preparation of Condensed financial statements according to U.S. GAAP.

Use of Estimates

The preparation of the Consolidated Financial Statements, in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited Interim Condensed Consolidated Financial Statements and accompanying notes. The Company evaluates its assumptions on an ongoing basis. The Company’s management believes that the estimates, judgment, and assumptions used are reasonable based upon information available at the time they are made. Significant estimates made by management include, among others, valuation of inventory, pension obligation, fair value of financial instruments including embedded derivatives, stock-based compensation, valuation of deferred income tax assets, and the estimated useful life of long-lived assets. Due to the inherent uncertainty involved in making assumptions and estimates, changes in circumstances, including those arising from the impacts of the COVID-19 pandemic, could result in actual results differing from those estimates, and such differences could be material to the Company’s consolidated financial condition and results of operations.

Recent Accounting Pronouncements Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the more timely recognition of losses. The new accounting standard will be effective for the fiscal year beginning on January 1, 2023, including interim periods within that year. The Company does not expect that adoption of this standard will have a material impact on its consolidated financial statements.

In December 2020, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which simplifies the accounting for income taxes. ASU 2019-12 is effective for nonpublic entities for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

FAIR VALUE MEASUREMENTS

In December 2020, in connection with issuance of Series B-1 preferred stock, the terms of Tranche 2 (Note 8) in the Series B preferred stock were amended to be identical to the B-1 preferred stock. This resulted in the fair value of the derivative liability associated with the Series B preferred stock right being reduced to zero value as of December 31, 2020, which expired as on June 30, 2021. In January 2021, Tranche 3 (Note

(UNAUDITED)

FAIR VALUE MEASUREMENTS (continued)

8) expired without exercise and, the Company recorded a change in fair value to reduce to zero the value of the derivative asset associated with Tranche 3 as of December 31, 2020.

The fair values of the preferred stock Tranche rights during the nine months ended September 30, 2020 were determined using the Monte Carlo simulation model. There were no changes in valuation techniques or transfers between the fair value measurement levels during the nine months period ended September 30, 2020.

The following table provides a reconciliation of all assets and liabilities measured at fair value using Level 3 significant unobservable inputs for the nine-months ended September 30, 2020:

	Preferred Stock Tranche Asset			Preferred Stock Tranche (Liability) Asset
Balance at January 1, 2020		$	12,527,000		$	(604,000)
Change in fair value			(10,684,670)			5,467,566
Balance at September 30, 2020		$	1,842,330		$	4,863,566

The unobservable inputs for Tranche 2 and Tranche 3, for which changes to the subjective amounts could impact the fair values presented above, were (1) probability to meet the tranche criteria and (2) the present value factor. As of September 30, 2020, the conditions for Tranche 2 were deemed to be 80% likely to be met and conditions for Tranche 3 were deemed to be 10% likely to be met if the Tranche 2 criteria were met. As of September 30, 2020, the present value factor for Tranche 2 was 0.9991 and Tranche 3 was 0.9983.

There were no other assets and liabilities measured at fair value for the nine months period ended September 30, 2021.

RELATED PARTY TRANSACTIONS

Loans Receivable

The Company had two loans receivable from an officer for funds advanced in connection with a relocation. The notes bore interest at 1.50% per annum and matured on December 31, 2019. The balance of the notes totaled $406,536 in aggregate as of December 31, 2020, which was repaid in full satisfaction of principal and accrued interest as of and for the nine months ended September 30, 2021. There was no related party receivable as of September 30, 2021.

Other

In May 2019, the Company received a $1,500,000 deposit for an “EV1” tower from a customer that is owned by one of its primary shareholders; the order remains outstanding as of September 30, 2021. The deposit and order were received before the owner of the customer became one of the Company’s primary shareholders and before it was represented on the Company’s board of directors. For the nine months ended September 30, 2021 and 2020, the Company paid consulting fees of $165,527 and $153,603, respectively, to the father of one of the Company’s executive officers. For the nine months ended September 30, 2021 and 2020, the Company paid $64,206 and $109,651, respectively, to a company owned by one of its primary shareholders in accordance with an agreement to provide certain legal, information technology, human resources, public relations and financial services.

Property and equipment, net		$	12,006,392		$	2,825,759

In June 2021, the Company decided to suspend further development of EV1 CDU prototype to focus on the next generation model EVx. The EV1 CDU prototype will continue to be used for the purpose of demonstration and testing. Accordingly, the identified components from the prototype amounting to $10,221,080 had been reclassified from inventory to property and equipment in the consolidated financial statement as of and for the nine months ended September 30, 2021 and the same will be depreciated to salvage value over a useful life of twenty-seven months beginning from April 1, 2021.

Further, a component pertaining to EV1 CDU prototype amounting to $458,095 was damaged and therefore written down to $0 by management in the consolidated financial statement for the nine months ended September 30, 2021. This write off has been partially off-set by an insurance claim amounting to $504,781 received by the Company and recorded as part of ‘inventory write-down’ in the consolidated financial statements. Additionally, other components, which weren’t previously installed, remain in inventory at their estimated net realizable value of $81,015, as the Company intends to sell them.

The Company plans to fulfill its contractual obligation for the existing sales order with the next generation EVx model.

For the nine months ended September 30, 2021 and 2020, depreciation and amortization related to property and equipment was $975,992 and $41,479 respectively. No impairments of long-lived assets were recorded for the nine months ended September 30, 2021 and 2020.

INTANGIBLE ASSETS — UNDER DEVELOPMENT

In April 2021, the Company signed a three-year licensing contract with regard to the implementation of an Enterprise Resource Planning (ERP) system. Subsequently, in May 2021, the Company signed a service agreement with an IT consulting firm to assist in the said implementation. As of September 30, 2021, the Company has recorded $178,366 as ‘Intangible assets — under development’.

NOTES PAYABLE

Paycheck Protection Program

In May 2020, the Company received loan proceeds amounting to $220,020 under the Paycheck Protection Program (“PPP”), which was established as part of the Coronavirus Aid, Relief and Economic Security (“CARES”) Act, administered through the Small Business Administration (“SBA”). The PPP

provides loans to qualifying businesses in amounts up to 2.5 times their average monthly payroll expenses and was designed to provide a direct financial incentive for qualifying businesses to keep their workforce employed during the Coronavirus crisis. PPP loans are uncollateralized and guaranteed by the SBA and are forgivable after a “covered period” (i.e., eight or twenty-four weeks) as long as the borrower maintains its payroll levels and uses the loan proceeds for eligible expenses, including payroll, benefits, mortgage interest, rent, and utilities. The forgiveness amount will be reduced, if the borrower terminates employees or reduces salaries and wages by more than 25% during the covered period. Any unforgiven portion is payable over 2 years, if issued before or 5 years if issued after June 5, 2020 at an interest rate of 1% per annum, with payments deferred until the SBA remits the borrower’s loan forgiveness amount to the lender, or, if the borrower does not apply for forgiveness, ten months after the end of the covered period. PPP loan terms provide for customary events of default, including payment defaults, breaches of representations and warranties, and insolvency events and may be accelerated upon the occurrence of one or more of these events of default. Additionally, PPP loan terms do not include prepayment penalties.

The management decided not to apply for forgiveness of the PPP loan and repaid the full balance of PPP loan and accrued interest to the relevant authority in September 2021.

Swiss Government COVID-19 Relief Loan

In March 2020, the Company’s wholly owned subsidiary received loan proceeds amounting to $518,645 under the Swiss Government COVID-19 Financial Assistance Program. The note bears no interest and matures 60 months from the date of issuance at which point its due and payable in full and accordingly recorded in the long-term liabilities under Notes payable, net of current portion. The Swiss Government COVID-19 Financial Assistance Program provides loans to qualifying businesses in amounts based on annual turnover and was designed to provide a direct financial incentive for qualifying businesses to keep their workforce employed during the Coronavirus crisis. These loans are uncollateralized and guaranteed by the Canton Government. On September 8, 2021, the Company repaid the full balance of the Swiss Government COVID-19 Relief Loan.

Conversion

Each class of preferred stock is convertible to common stock at the option of the holder at the conversion price (as defined in the articles of incorporation) which is initially equal to the original issuance price of each of the preferred stock issuances. The preferred stock is automatically converted to common stock upon the earlier of; (a) a firm commitment underwritten initial public offering to an effective registration statement and sale of common stock to the public of not less than $49.0258 per share (minimum price per share does not apply to Series FR, Seed 1 and Seed 2 preferred stock) with gross proceeds not less than $50 million, or (b) by written consent of the holders of a majority of the then outstanding shares of preferred stock voting as single class on an as-converted to common stock basis, with the holders of the Series A, Seed 2, Seed 1, and Series FR preferred stock voting as a separate class on an as-converted basis, the holders of the Series B voting as a separate class on an as-converted basis, the holders of the Series B-1 voting as a separate class on an as-converted basis, and the holders of the Series C voting as a separate class on an as-converted basis.

Liquidation

Upon liquidation, dissolution, or winding up of the Company, the holders of Series B, Series B-1 and Series C preferred stock are entitled to, in preference to the holders of each of the other classes of preferred stock, and to the common stockholder, an amount equal to the original issuance price plus declared but unpaid dividends. After payment in full to the holders of Series B, Series B-1 and Series C preferred stock, and prior to any distribution to the common stockholders, each of the other classes of preferred stock are entitled to receive an amount equal to the original issue price plus declared and unpaid dividends on such shares, payable on a pari-passu basis among the Series.

Voting

Each share of preferred stock is entitled to the number of votes equal to the number of shares of common stock into which the shares of preferred stock so held could be converted at the record date.

Series B Tranche Rights

The Series B preferred stock purchase agreement included terms that obligated the investors to purchase, and the Company to sell, two subsequent rounds of Series B preferred stock in tranche closings

(the “Tranche Rights”), the first of which is for proceeds totaling $45,000,000 in exchange for shares in the capital of the Company resulting in the holding of 35.27% of the shares of the Company on a fully diluted basis (“Tranche 2”), and the second for proceeds totaling $40,000,000 in exchange for shares in the capital of the Company resulting in the holding of 37.82% of the shares of the Company on a fully diluted basis (“Tranche 3”). The terms of the Tranche 2 and Tranche 3 preferred shares were substantially identical to the Series B preferred stock except with respect to purchase price. The issuance of Tranche 2 and Tranche 3 was subject to and conditioned upon the successful deployment of the Prototype and the Company reaching certain commercial milestones as described in the stock purchase agreement. The deadline for completion of the Tranche requirements was 18 months from the closing date of Series B preferred stock purchase agreement or January 2021. In December 2020, in connection with issuance of Series B-1 preferred stock, the terms of Tranche 2 in the Series B preferred stock were amended to be identical to the B-1 preferred stock, and the deadline for the completion of certain milestones in the development of the Prototype was extended to June 30, 2021. In January and June 2021, the Tranche 3 and Tranche 2, respectively, deadline expired. The Tranche Rights were transferable by the investors, and separately exercisable.

Tranche 2 was initially recorded as a liability of $834,613 as the purchase price of the additional shares was less than the estimated value of the Series B preferred stock at the expected settlement date. Conversely, Tranche 3 was initially recorded as an asset of $12,351,206 as the purchase price of the additional shares was greater than the estimated price of the Series B preferred stock at the expected settlement date. Remeasurement of Tranche 2 and Tranche 3 resulted in a net loss on the change in fair value of derivatives totaling $5,217,104 for the nine months ended September 30, 2020. The Company measured the fair value of the Tranche rights at each measuring date using the Monte Carlo simulation model adjusted for probability of future Tranche financing.

Common Stock

As of September 30, 2021 and December 31, 2020, the Company was authorized to issue 17,800,000, shares of common stock, with a par value of $0.0001 per share. As of September 30, 2021 and December 31, 2020, common shares issued and outstanding were 3,038,093 and 2,148,210, respectively.

STOCK-BASED COMPENSATION

In 2017, the Company adopted its 2017 Stock Incentive Plan (the “2017 Plan”) which provides for the granting of stock options, restricted stock, and Restricted Stock Units (“RSU”) to employees, directors, and consultants of the Company. Options granted under the 2017 Plan were either Incentive Stock Options (“ISOs”) or Nonqualified Stock Options (“NSOs”). Awards under the 2017 Plan may be granted for periods of up to ten years. Under the terms of the 2017 Plan, awards may be granted at an exercise price not less than the estimated fair value of the shares on the date of grant, as determined by the Company’s Board of Directors. For employees holding more than 10% of the voting rights of all classes of stock, the exercise price of ISOs and NSOs may not be less than 110% of the estimated fair value of the shares on the date of grant, as determined by the board of directors. Awards generally vest over one to four years.

In 2020, the Company adopted its 2020 Stock Incentive Plan (the “2020 Plan”) which superseded the previous 2017 Stock Incentive Plan. The 2020 plan provides for the granting of stock options, restricted stock, and RSU to employees, directors, and consultants of the Company. Options granted under the 2020 Plan may be either Incentive Stock Options (“ISOs”) or Nonqualified Stock Options (“NSOs”). Awards under the 2020 Plan may be granted for periods of up to ten years. Under the terms of the 2020 Plan, awards may be granted at an exercise price not less than the estimated fair value of the shares on the date of grant, as determined by the Company’s Board of Directors. For employees holding more than 10% of the voting rights of all classes of stock, the exercise price of ISOs and NSOs may not be less than 110% of the estimated fair value of the shares on the date of grant, as determined by the board of directors. Awards generally vest over one to four years.

Stock Option Activity

Stock option activity under the 2017 and 2020 Plans for the nine months ended September 30, 2021 is as follows:

	Options Outstanding
	Number of Options		Weighted Average Exercise Price Per Share			Weighted Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value
Balance as of December 31, 2020		85,000		$	0.63		7.48		$	422,500

Options vested and expected to vest as of September 30, 2021		177,000		$	4.78		9.11		$	520,116

As of September 30, 2021, total unamortized stock-based compensation expense related to unvested awards that are expected to vest was $416,145. The weighted-average period over which such stock-based compensation expense will be recognized is approximately 1.96 years.

The aggregate intrinsic values of options outstanding, exercisable, vested and expected to vest were calculated as the difference between the exercise price of the options and the estimated fair value of the Company’s common stock, as determined by the Board of Directors and recent transactions. During the nine months ended September 30, 2021, 147,000 options to purchase shares of Common Stock were granted. No options were granted during the nine months ended September 30, 2020.

The fair value of stock option awards was determined on the grant date using the Black-Scholes valuation model based on the following weighted-average assumptions:

Expected volatility		90%
Common stock value	$	7.53
Risk free interest rate		0.06%
Expected dividend yield		—
Expected term (years)		6.25

STOCK-BASED COMPENSATION (continued)

Risk-Free Interest Rate — The risk-free interest rate is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected term of option.

Expected Dividend — The Company has never paid dividends on its common stock and has no plans to pay dividends on its common stock. Therefore, the Company used an expected dividend yield of zero.

Restricted Stock Units

The Company has granted two-tier Restricted Stock Units (“RSUs”) under the 2020 Plan. These RSUs have both a service-based vesting condition and liquidity event-based vesting condition. The service-based vesting period for these awards is generally four years with a cliff vesting period of one year and continue to vest monthly thereafter. The liquidity event-based vesting condition is satisfied on the earlier occurrence of either a qualified transaction, which includes IPO, SPAC Transaction, or a Direct Listing, or a Sale Event that earns specified multiples of money and internal rates of return.

Based on the qualified transaction condition, the employees would get acceleration for 50% of their RSUs even if they do not have sufficient service to the Company to achieve this level of vesting.

In July 2021, the Company granted 588,117 RSUs with a weighted average grant date fair value of $4.95 per share, which will vest based upon the satisfaction of both a service-based condition and a liquidity event-based condition. The Company measured the fair value of the RSUs using the Monte Carlo simulation model at the grant date. The Company will begin to recognize compensation expense for these RSUs using the accelerated attribution method when the required liquidity event-based vesting condition becomes probable, which the Company has determined is when the liquidity event occurs. As of September 30, 2021, no liquidity event has occurred, so the Company did not recognize any stock-based compensation expense for these RSUs. As of September 30, 2021, unrecognized stock-based compensation expense related to these RSUs was $2,911,179 which is expected to be recognized over the remaining weighted-average vesting period of approximately 1.66 years. No RSUs were granted during the nine months ended September 30, 2020.

Restricted stock units activity for the nine months ended September 30, 2021 is as follows:

	Share		Weighted Average Grant Date Fair Value per Share
Balance as of December 31, 2020		—		$	—
Restricted Stock units granted		588,117			4.95

Unvested Common Stock/Restricted Stock Awards

The Company has certain common stocks that are subject to repurchase at the election of the Company. These repurchase rights expire over time and therefore are accounted for as unvested common stock.

In July 2021, the Company granted 834,883 Restricted Stock Awards (“RSAs”) with a weighted average grant date fair value of $4.95 per share. Out of 834,883 RSAs, 20,000 of which vested immediately, and the remaining will vest based upon the satisfaction of both a service-based condition and a liquidity event-based condition. The Company measured the fair value of the RSUs using the Monte Carlo simulation model at the grant date. The Company has recognized compensation expense for the vested RSAs and will begin to recognize compensation expense for the remaining RSAs using the accelerated attribution method when the required liquidity event-based vesting condition becomes probable, which the Company has determined is when the liquidity event occurs. As of September 30, 2021, no liquidity event has occurred, so the Company did not recognize any stock-based compensation expense for these RSAs. As of September 30, 2021, unrecognized stock-based compensation expense related to these RSAs was $4,031,634 which is expected to be recognized over the remaining weighted-average vesting period of approximately 1.91 years. No RSAs were granted during the nine months ended September 30, 2020.The following table summarizes information about outstanding unvested stock activities:

	Unvested Common Stock
Balances outstanding at December 31, 2020		450,424

NET LOSS PER SHARE OF COMMON STOCK (continued)

There is no common stock and convertible preferred stock that were dilutive for the nine months ended September 30, 2021 and 2020. Due to net losses for the nine months ended September 30, 2021 and 2020, basic and diluted net loss per common share were the same, as the effect of potentially dilutive securities would have been anti-dilutive. The following outstanding balances of common share equivalent securities have been excluded from the calculation of diluted weighted-average common shares outstanding because the effect is anti-dilutive for the periods presented:

	Nine Months Ended September 30,

INCOME TAXES

The Company did not record a tax provision for the nine months ended September 30, 2021 and 2020, respectively, due to the losses, and accordingly, has recorded a valuation allowance against substantially all of the Company’s net deferred tax assets. The Company provides for a valuation allowance when it is more likely than not that some portion of, or all of the Company’s deferred tax assets will not be realized. Due to the Company’s history of losses, the Company determined that it is not more likely than not to realize its deferred tax assets.

COMMITMENTS AND CONTINGENCIES

Leases

The Company has operating leases for its corporate offices and field offices. The Company recognized a Right-of-Use (“ROU”) asset and lease liability for operating leases based on the net present value of future minimum lease payments. Lease expense is recognized on a straight-line basis over the non-cancelable lease term and renewal periods that are considered reasonably certain.

The Company has finance leases for vehicles. The Company recognized a ROU asset and lease liability for finance leases based on the net present value of future minimum lease payments. Lease expense for the Company’s finance leases is comprised of the amortization of the right of use asset and interest expense recognized based on the effective interest method.

The Company has elected to use hindsight in determining the lease term (that is, when considering lessee options to extend or terminate the lease or to purchase the underlying asset) and in assessing impairment of the entity’s ROU assets. Accordingly, management’s decisions regarding lease renewals that are reasonably certain to be exercised have been incorporated as part of the lease term in ROU asset and lease liability calculations. To support these determinations, the Company evaluated each active lease at transition that included a renewal option (or options) to assess whether or not the future renewal options were reasonably certain to be exercised. The periods related to any renewal options deemed not reasonably certain to be exercised were excluded from the lease term for the ROU asset and lease liability calculations.

Lease Modifications

In June 2020, the Company obtained additional rights to land and structures that were contiguous to its existing land lease. The increase in lease payments related to the lease modification was not commensurate with the standalone price for the additional ROU associated with the land and structures when compared to the original lease. Consequently, these adjustments to the terms of the lease were treated as a modification of the original lease. A net adjustment was made to the ROU asset and lease liability amounting to $237,516. In September 2021, this lease was further extended for one year resulting in net adjustment to the right-of-use asset and lease liability amounting to $264,710.

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2020

NOTE 1 — DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

Novus Capital Corporation II (the “Company”) is a blank check company incorporated in Delaware on September 29, 2020. The Company was formed for the purpose of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses (the “Business Combination”). The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

The Company is not limited to a particular industry or sector for purposes of consummating a Business Combination although it intends to focus on target businesses that are at the forefront of high technology and are enabling the future evolution of smart technologies, 5G communication, virtual reality, artificial intelligence, spatial computing, cloud analytics, machine learning, hardware and software distribution, value added customized logistics services, sustainable smart city systems and sustainable agricultural technology, or AgTech.

As of December 31, 2020, the Company had not commenced any operations. All activity for the period from September 29, 2020 (inception) through December 31, 2020 relates to the Company’s formation and the initial public offering (the “Initial Public Offering”), which is described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income on cash and cash equivalents in the form of interest income from the proceeds derived from the Initial Public Offering.

The registration statement for the Company’s Initial Public Offering was declared effective on February 3, 2021. On February 8, 2021, the Company consummated the Initial Public Offering of 28,750,000 units (the “Units” and, with respect to the shares of Class A common stock included in the Units sold, the “Public Shares”), which includes the full exercise by the underwriter of its over-allotment option in the amount of 3,750,000 Units, at $10.00 per Unit, generating gross proceeds of $287,500,000, which is described in Note 3.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 5,166,666 warrants (each, a “Private Placement Warrant” and, collectively, the “Private Placement Warrants”) at a price of $1.50 per Private Placement Warrant in a private placement to the Company’s initial stockholders, including Cowen Investments (an affiliate of one of the underwriters), generating gross proceeds of $7,750,000, which is described in Note 4.

Transaction costs amounted to $6,224,714, consisting of $5,750,000 of underwriting fees, and $474,714 of other offering costs.

Following the closing of the Initial Public Offering on February 8, 2021, an amount of $287,500,000 ($10.00 per Public Unit) from the net proceeds of the sale of the Public Units in the Initial Public Offering and the sale of the Private Placement Warrants was placed in a trust account (the “Trust Account”), and will be invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less, or in any open-ended investment company that holds itself out as a money market fund meeting certain conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the funds in the Trust Account to the Company’s stockholders, as described below, except that interest earned on the Trust Account can be released to the Company to pay its tax obligations (“permitted withdrawals”).

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The Company’s Business Combination must be with one or more target businesses that together have a

fair market value equal to at least 80% of the balance in the Trust Account (as defined below) (excluding taxes payable on interest earned on the Trust Account) at the time of the signing a definitive agreement to enter a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a Business Combination.

The Company will provide its holders of the outstanding Public Shares (the “public stockholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The public stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $10.00 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants.

The Company will proceed with a Business Combination only if the Company has net tangible assets of at least $5,000,001 either prior to or upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation (the “Amended and Restated Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or other reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with a Business Combination, the initial stockholders and Cowen Investments have agreed to vote their Founder Shares (as defined in Note 5) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, each public stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction or don’t vote at all.

The initial stockholders and Cowen Investments agreed for no additional consideration in connection with the IPO (a) to waive their redemption rights with respect to their Founder Shares and Public Shares held by them in connection with the completion of a Business Combination, (b) to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within by February 8, 2023 and (c) not to propose an amendment to the Amended and Restated Certificate of Incorporation (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of its Public Shares if the Company does not complete a Business Combination or (ii) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity, unless the Company provides the public stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment. However, if the initial stockholders and Cowen Investments acquire Public Shares in or after the Initial Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period.

The Company will have until February 8, 2023 to complete a Business Combination (the “Combination Period”). If the Company is unable to complete a Business Combination within the Combination Period,

the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the Company’s warrants, which will expire worthless if the Company fails to complete a Business Combination within the Combination Period.

In order to protect the amounts held in the Trust Account, V Donargo LLC, an entity controlled by Vincent Donargo, the Company’s Chief Financial Officer, has agreed to be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (1) $10.00 per Public Share or (2) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay our taxes. This liability will not apply with respect to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, V Donargo LLC will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that V Donargo LLC will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (except the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Liquidity and Management’s Plan

Prior to the completion of the initial public offering, the Company lacked the liquidity it needed to sustain operations for a reasonable period of time, which is considered to be one year from the issuance date of the financial statement. The Company has since completed its Initial Public Offering at which time capital in excess of the funds deposited in the Trust Account and/or used to fund offering expenses was released to the Company for general working capital purposes. Accordingly, management has since reevaluated the Company’s liquidity and financial condition and determined that sufficient capital exists to sustain operations for a reasonable period of time, which is considered to be one year from the issuance date of the financial statementsand therefore substantial doubt has been alleviated.

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 pandemic and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of the financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC.

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period.

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of December 31, 2020.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Deferred Offering Costs

Deferred offering costs consisted of legal, accounting and other expenses incurred through the balance sheet date that were directly related to the Initial Public Offering. On February 8, 2021, offering costs amounting to $6,224,714 were charged to Stockholders’ equity upon the completion of the Initial Public Offering (see Note 1). As of December 31, 2020, there were $37,042 of deferred offering costs recorded in the accompanying balance sheet.

Income Taxes

The Company complies with the accounting and reporting requirements of ASC Topic 740, “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.

The provision for income taxes was deemed to be immaterial as of December 31, 2020.

Net Loss Per Common Share

Net loss per share of common stock is computed by dividing net loss by the weighted average number of common shares outstanding during the period, excluding shares of common stock subject to forfeiture. Weighted average shares were reduced for the effect of an aggregate of 937,500 shares of Class B common stock that were subject to forfeiture by the Sponsor if the over-allotment option is not exercised by the underwriters (see Note 5). At December 31, 2020, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into common stock and then share in the earnings of the Company. As a result, diluted loss per share is the same as basic loss per share for the period presented.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company had not experienced losses on this account.

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the Company’s balance sheet, primarily due to their short-term nature.

Recent Accounting Standards

Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s financial statements.

NOTE 3 — INITIAL PUBLIC OFFERING

Pursuant to the Initial Public Offering, the Company sold 28,750,000 Units, which includes the full exercise by the underwriter of its over-allotment option in the amount of 3,750,000 Units, at a purchase price of $10.00 per Unit. Each Unit will consist of one share of the Company’s Class A common stock and one-third of one redeemable warrant (“Public Warrant”). Each whole Public Warrant will entitle the holder to purchase one share of Class A common stock at an exercise price of $11.50 per whole share (see Note 7).

NOTE 4 — PRIVATE PLACEMENT

Simultaneously with the closing of the Initial Public Offering, the initial stockholders and Cowen Investments purchased an aggregate of 5,166,666 Private Placement Warrants at a price of $1.50 per Private Placement Warrant ($7,750,000 in the aggregate) in a private placement. Each Private Placement Warrant is exercisable to purchase one share of Class A common stock at a price of $11.50 per share. The proceeds from the sale of the Private Placement Warrants were added to the net proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Warrants will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless.

NOTE 5 — RELATED PARTY TRANSACTIONS

Founder Shares

On October 12, 2020, the initial stockholders and Cowen Investments (“Founders”) purchased an aggregate of 7,187,500 shares of Class B common stock (the “Founder Shares”) for an aggregate purchase price of $25,000. The Founder Shares include an aggregate of up to 937,500 shares subject to forfeiture by the initial stockholders to the extent that the underwriter’s over-allotment is not exercised in full or in part, so that the Sponsor will collectively own, on an as-converted basis, 20% of the Company’s issued and outstanding shares after the Initial Public Offering (assuming the Sponsor does not purchase any Public Shares in the Initial Public Offering). As a result of the underwriters’ election to fully exercise their over-allotment option, no Founder Shares are currently subject to forfeiture.

The initial stockholders and Cowen Investments have agreed, subject to certain limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier to occur of: (1) one year after the completion of a Business Combination or (B) subsequent to a Business Combination, (x) if the last reported sale price of the Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after a Business Combination, or (y) the date on which the Company completes a liquidation, merger, capital stock exchange or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of common stock for cash, securities or other property.

NOTE 5 — RELATED PARTY TRANSACTIONS (continued)

“Promissory Notes”). The Promissory Notes are non-interest bearing and are payable on the earlier of (i) September 30, 2021 and (ii) the consummation of the Initial Public Offering. As of December 31, 2020, the Company had $160,000 outstanding under the Notes, which is currently due on demand. The outstanding balance under the Promissory Note of $80,000 was subsequently repaid on February 8, 2021, while the remaining $80,000 was repaid on February 10, 2021.

Related Party Loans

In order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor or certain of the Company’s directors and officers may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $2,000,000 of such Working Capital Loans may be convertible into warrants of the post-Business Combination entity at a price of $1.50 per warrant. The warrants would be identical to the Private Placement Warrants.

NOTE 6 — COMMITMENTS AND CONTINGENCIES

Registration Rights

Pursuant to a registration rights agreement entered into on February 3, 2021, the holders of the Founder Shares, Private Placement Warrants and any warrants that may be issued upon conversion of the Working Capital Loans (and any shares of Class A common stock issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans) will have registration rights to require the Company to register a sale of any of the securities for resale (in the case of the Founder Shares, only after conversion to shares of Class A common stock). The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of a Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. Notwithstanding the foregoing, Cowen Investments may not exercise its demand and “piggyback” registration rights after five and seven years, respectively, after the effective date of the Initial Public Offering. The registration rights agreement does not contain liquidating damages or other cash settlement provisions resulting from delays in registering the Company’s securities. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The underwriters are entitled to a cash underwriting discount of $0.20 per Unit, or $5,750,000 which was paid upon the closing of the Initial Public Offering.

and the target business’ attributes, introduce the Company to potential investors that are interested in purchasing the Company’s securities in connection with a Business Combination, provide financial advisory services to assist the Company in the Company’s efforts to obtain any stockholder approval for the Business Combination and assist the Company with its press releases and public filings in connection with the Business Combination. The Company will pay the underwriters a cash fee for such services upon the consummation of a Business Combination in an amount equal to, in the aggregate, 3.5% of the gross proceeds of Initial Public Offering.

NOTE 7 — STOCKHOLDERS’ EQUITY

Preferred Stock — The Company was authorized to issue 5,000,000 shares of preferred stock, $0.0001 par value per share. At December 31, 2020, there were no shares of preferred stock issued or outstanding.

Class A Common Stock — The Company was authorized to issue up to 500,000,000 shares of Class A common stock, $0.0001 par value per value. Holders of the Company’s common stock are entitled to one vote for each share. At December 31, 2020, there were no shares of Class A common stock issued or outstanding.

Class B Common Stock — The Company was authorized to issue up to 20,000,000 shares of Class B common stock, $0.0001 par value per share. Holders of the Company’s common stock are entitled to one vote for each share. At December 31, 2020, there were 7,187,500 shares of Class B common stock issued or outstanding.

Holders of Class A common stock and Class B common stock will vote together as a single class on all other matters submitted to a vote of stockholders, except as required by law.

The shares of Class B common stock will automatically convert into shares of Class A common stock at the time of a Business Combination, or earlier at the option of the holder, on a one-for-one basis, subject to adjustment. In the case that additional shares of Class A common stock, or equity-linked securities, are issued or deemed issued in excess of the amounts issued in Initial Public Offering and related to the closing of a Business Combination, the ratio at which shares of Class B common stock shall convert into shares of Class A common stock will be adjusted (unless the holders of a majority of the outstanding shares of the Class B common stock agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B common stock will equal, in the aggregate, on an as-converted basis, 20% of the total number of all shares of common stock outstanding upon completion of the Initial Public Offering plus all shares of Class A common stock and equity-linked securities issued or deemed issued in connection with a Business Combination (net of the number of shares of Class A common stock redeemed in connection with a Business Combination), excluding any shares or equity-linked securities issued, or to be issued, to any seller in a Business Combination.

Warrants — Public Warrants may only be exercised for a whole number of shares. No fractional shares will be issued upon exercise of the Public Warrants. The Public Warrants will become exercisable 30 days after the consummation of a Business Combination. The Public Warrants will expire five years from the consummation of a Business Combination or earlier upon redemption or liquidation.

The Company will not be obligated to deliver any Class A common stock pursuant to the exercise of a Public Warrant and will have no obligation to settle such Public Warrant exercise unless a registration statement under the Securities Act covering the issuance of the shares of Class A common stock issuable upon exercise of the warrants is then effective and a current prospectus relating to those shares of Class A common stock is available, subject to the Company satisfying its obligations with respect to registration. No warrant will be exercisable for cash or on a cashless basis, and the Company will not be obligated to issue

NOTE 7 — STOCKHOLDERS’ EQUITY (continued)

any shares to holders seeking to exercise their warrants, unless the issuance of the shares upon such exercise is registered or qualified under the securities laws of the state of the exercising holder, or an exemption from registration is available.

The Company has agreed that as soon as practicable, but in no event later than 20 business days after the closing of a Business Combination, the Company will use its commercially reasonable efforts to file with the SEC, and within 60 business days following a Business Combination to have declared effective, a registration statement covering the issuance of the shares of Class A common stock issuable upon exercise of the warrants and to maintain a current prospectus relating to those shares of Class A common stock until the warrants expire or are redeemed. Notwithstanding the above, if the Class A common stock is at the time of any exercise of a warrant not listed on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, but will use its commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

Redemption of Warrants When the Price per share of Class A common stock Equals or Exceeds $18.00 — Once the warrants become exercisable, the Company may redeem the outstanding Public Warrants (except with respect to the Private Placement Warrants):

•

in whole and not in part;

•

at a price of $0.01 per warrant;

•

upon a minimum of 30 days’ prior written notice of redemption, or the 30-day redemption period, to each warrant holder; and

•

if, and only if, the last reported sale price of the Class A common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders.

If and when the warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

Redemption of Warrants When the Price per share of Class A common stock Equals or Exceeds $10.00 — Commencing ninety days after the warrants become exercisable, the Company may redeem the outstanding warrants (except with respect to the Private Placement Warrants):

•

in whole and not in part;

•

at a price of $0.10 per warrant provided that holders will be able to exercise their warrants prior to redemption and receive that number of shares of Class A common stock determined based on the redemption date and the fair market value of the Class A common stock;

•

upon a minimum of 30 days’ prior written notice of redemption;

•

if, and only if, the last reported sale price of the Class A common stock equals or exceeds $10.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) on the trading day prior to the date on which the Company sends the notice of redemption to the warrant holders; and

•

if, and only if, there is an effective registration statement covering the issuance of the shares of Class A common stock issuable upon exercise of the warrants and a current prospectus relating thereto available throughout the 30-day period after written notice of redemption is given.

The exercise price and number of Class A common stock issuable upon exercise of the Public Warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation. However, except as described below, the Public Warrants will not be adjusted for issuances of Class A common stock at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the Public Warrants. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of Public Warrants will not receive any of such funds with respect to their Public Warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with respect to such Public Warrants. Accordingly, the Public Warrants may expire worthless.

In addition, if (x) the Company issues additional shares of Class A common stock or equity-linked securities for capital raising purposes in connection with the closing of a Business Combination at an issue price or effective issue price of less than $9.20 per share of Class A common stock (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors and, in the case of any such issuance to the initial stockholders or their affiliates, without taking into account any Founder Shares held by the initial stockholders or their affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of a Business Combination on the date of the completion of a Business Combination (net of redemptions), and (z) the volume weighted average trading price of the Class A common stock during the 20 trading day period starting on the trading day prior to the day on which the Company completes a Business Combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price.

The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants will and the common shares issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be exercisable on a cashless basis and will be non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER 30, 2021
(UNAUDITED)

NOTE 1. DESCRIPTION OF ORGANIZATION, BUSINESS OPERATIONS AND GOING CONCERN

The Company has one wholly owned subsidiary which was formed on September 2, 2021, NCCII Merger Corp. (the “Merger Sub”), a Delaware corporation.

The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. The Company is not limited to a particular industry or sector for purposes of consummating a Business Combination although it intends to focus on target businesses that are at the forefront of high technology and are enabling the future evolution of smart technologies, 5G communication, virtual reality, artificial intelligence, spatial computing, cloud analytics, machine learning, hardware and software distribution, value added customized logistics services, sustainable smart city systems and sustainable agricultural technology, or AgTech.

As of September 30, 2021, the Company had not commenced any operations. All activity from inception through September 30, 2021 related to the Company’s formation and the initial public offering (the “Initial Public Offering”) and its search for a target business for a Business Combination, which is described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income on cash and cash equivalents in the form of interest income from the proceeds derived from the Initial Public Offering. On September 8, 2021, the Company, Merger Sub and Energy Vault, Inc (“Energy Vault”) entered into a business combination agreement relating to a proposed business combination with (see Note 7).

Transaction costs amounted to $6,224,714, consisting of $5,750,000 of underwriting fees, and $474,714 of other offering costs.

Following the closing of the Initial Public Offering on February 8, 2021, $287,500,000 ($10.00 per Public Unit) from the net proceeds of the sale of the Public Units in the Initial Public Offering and the sale of the Private Placement Warrants was placed in a trust account (the “Trust Account”), and invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less, or in any open-ended investment company that holds itself out as a money market fund meeting certain conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the funds in the Trust Account to the

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER 30, 2021
(UNAUDITED)

Company’s stockholders, as described below, except that interest earned on the Trust Account can be released to the Company to pay its tax obligations (“permitted withdrawals”).

White the Company’s management has broad discretion with respect to the specific application of cash held outside of the Trust Account, substantially all of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, which are placed in the Trust Account, are intended to be applied generally toward completing a Business Combination. The Company’s Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (as defined below) (excluding taxes payable on interest earned on the Trust Account) at the time of the signing a definitive agreement to enter a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a Business Combination.

The Company will provide its stockholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The public stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $10.00 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants.

The Company will proceed with a Business Combination only if the Company has net tangible assets of at least $5,000,001 either prior to or upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation (the “Amended and Restated Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or other reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with a Business Combination, the initial stockholders and Cowen Investments have agreed to vote their Founder Shares (as defined in Note 6) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, each public stockholder may elect to redeem their Public Shares, without voting, and if they do vote, irrespective of whether they vote for or against the proposed Business Combination.

The initial stockholders and Cowen Investments have agreed (a) to waive their redemption rights with respect to their Founder Shares and Public Shares held by them in connection with the completion of a Business Combination, (b) to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within by February 8, 2023 and (c) not to propose an amendment to the Amended and Restated Certificate of Incorporation (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of its Public Shares if the Company does not complete a Business Combination or (ii) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity, unless the Company provides the public stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment. However, if the initial stockholders

(UNAUDITED)

and Cowen Investments acquire Public Shares in or after the Initial Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period.

The Company has until February 8, 2023 to complete a Business Combination (the “Combination Period”). If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the Company’s warrants, which will expire worthless if the Company fails to complete a Business Combination within the Combination Period.

Risks and Uncertainties

Going Concern

As of September 30, 2021, the Company had $882,585 in its operating bank accounts and a working capital of $779,120. As of September 30, 2021, $9,721 of the amount on deposit in the Trust Account represented interest income, which is available to be withdrawn to pay taxes.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER 30, 2021
(UNAUDITED)

Until the consummation of a Business Combination, the Company will be using the funds not held in the Trust Account for identifying and evaluating prospective acquisition candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to acquire, and structuring, negotiating and consummating the Business Combination.

The Company will need to raise additional funds through loans or additional investments from its Sponsor, stockholders, officers, directors, or third parties. The Company’s officers, directors and Sponsor may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. These conditions raise substantial doubt about the Company’s ability to continue as a going concern for at least one year from the date that the financial statements are issued. These financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern.

NOTE 2. RESTATEMENT OF PREVIOUSLY ISSUED FINANCIAL STATEMENTS

In connection with the preparation of the Company’s financial statements as of September 30, 2021, management identified errors made in its historical financial statements where, the Company improperly classified some of its Class A common stock subject to possible redemption. In accordance with ASC 480-10-S99, redemption provisions not solely within the control of the Company would require common stock subject to redemption to be classified outside of permanent equity. The Company had previously classified some Class A common stock shares in permanent equity. Although the Company did not specify a maximum redemption threshold, its charter provides that currently, the Company will not redeem its public shares in an amount that would cause its net tangible assets to be less than $5,000,001. The Company restated its financial statements to classify all Class A Common Stock as temporary equity and for any related impact, as the threshold in its charter would not change the nature of the underlying shares as redeemable and thus would be required to be presented outside of permanent equity.

In connection with the change in presentation for the Class A common stock subject to redemption, the Company also restated its income (loss) per common share calculation to allocate net income (loss) evenly to Class A and Class B common stock. This presentation contemplates a Business Combination as the most likely outcome, in which case, both classes of common stock share pro rata in the income (loss) of the Company.

The following tables summarize the effect of the restatement on each financial statement line item as of the dates, and for the period, indicated:

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the SEC. Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information

and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented.

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the period ended December 31, 2020, as filed with the SEC on March 26, 2021. The interim results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results to be expected for the year ending December 31, 2021 or for any future periods.

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation.

the near term due to one or more future confirming events. One of the more significant accounting estimates included in these condensed consolidated financial statements is the determination of the fair value of the warrant liabilities. Such estimates may be subject to change as more current information becomes available and accordingly, the actual results could differ significantly from those estimates.

Cash and Cash Equivalents

Marketable Securities Held in Trust Account

At September 30, 2021 and December 31, 2020, substantially all of the assets held in the Trust Account were held in money market funds which are invested primarily in U.S. Treasury securities. All of the Company’s investments held in the Trust Account are classified as trading securities. Trading securities are presented on the balance sheet at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of investments held in Trust Account are included in interest earned on marketable securities held in Trust Account in the accompanying condensed consolidated statements of operations. The estimated fair values of investments held in Trust Account are determined using available market information.

Offering Costs

Offering costs consisted of legal, accounting and other expenses incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs were allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs allocated to warrant liabilities were expensed as incurred in the statements of operations. Offering costs associated with the Class A common stock issued were charged to temporary equity. Offering costs amounted to $6,224,714, of which $5,983,403 were charged against temporary equity and $241,311 were expensed on the Statement of Operations

Class A Common Stock Subject to Possible Redemption

The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Shares of Class A common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that is either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s Class A common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at September 30, 2021, Class A common stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet.

The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable common stock to equal the redemption value at the end of each reporting period. Increases or decreases in the carrying amount of redeemable common stock are affected by charges against additional paid in capital and accumulated deficit.

At September 30, 2021, the Class A common stock reflected in the condensed consolidated balance sheet are reconciled in the following table:

Warrant Liabilities

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own common stock, among other conditions for equity classification. This assessment is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded as a liability at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the statements of operations.

The Company accounts for the Public Warrants and Private Placement Warrants (together with the Public Warrants, the “Warrants”) in accordance with the guidance contained in ASC 815-40. The Warrants are not considered indexed to the Company’s own common stock, and as such, the Warrants do not meet the criteria for equity treatment and must be recorded as liabilities. The Private Placement Warrants and the Public Warrants for periods where no observable traded price was available were valued using the Modified Monte Carlo Simulation and Modified Black Scholes option pricing models (see Note 9).

Income Taxes

ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of September 30, 2021 and December 31, 2020. The Company is currently not

(UNAUDITED)

aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. The Company’s effective tax rates for the periods presented differ from the expected (statutory) rates due to start-up costs not being currently deductible, the recording of full valuation allowances on deferred tax assets and permanent differences.

Net Income (Loss) Per Share

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share”. Net income (loss) per common stock is computed by dividing net income (loss) by the weighted average number of common stock outstanding for the period. The Company applies the two-class method in calculating earnings per share. Remeasurement adjustment associated with the redeemable shares of Class A common stock is excluded from earnings per share as the redemption value approximates fair value.

The calculation of diluted income (loss) per share does not consider the effect of the warrants issued in connection with the (i) Initial Public Offering, and (ii) the private placement. The warrants are exercisable to purchase 14,749,999 Class A common stock in the aggregate. As of September 30, 2021 and 2020, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into common stock and then share in the earnings of the Company. As a result, diluted net loss per common stock is the same as basic net loss per common stock for the periods presented.

The following table reflects the calculation of basic and diluted net income (loss) per share (in dollars, except per share amounts):

	Three Months Ended September 30, 2021						Nine Months Ended September 30, 2021						For the Period from September 29, 2020 (Inception) Through September 30, 2020

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC 820, “Fair Value Measurement,” approximates the carrying amounts represented in the condensed consolidated balance sheets, primarily due to their short-term nature, except for warrant liabilities (see Note 9).

Recent Accounting Standards

In August 2020, the FASB issued ASU No. 2020-06, “Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted. The Company is currently assessing the impact, if any, that ASU 2020-06 would have on its financial position, results of operations or cash flows.

Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s condensed consolidated financial statements.

NOTE 4. INITIAL PUBLIC OFFERING

On February 8, 2021, the Company sold 28,750,000 Units which includes the full exercise by the underwriters of their over-allotment option in the amount of 3,750,000 Units at a purchase price of $10.00 per Unit. Each Unit consists of one share of the Company’s Class A common stock and one-third of one redeemable warrant (“Public Warrant”). Each Public Warrant entitles the holder to purchase one share of Class A common stock at an exercise price of $11.50 per whole share.

NOTE 5. PRIVATE PLACEMENT

Simultaneously with the closing of the Initial Public Offering, the Sponsor purchased an aggregate of 5,166,666 Private Placement Warrants at a price of $1.50 per Private Placement Warrant ($7,750,000 in the aggregate), each exercisable to purchase one share of Class A common stock at a price of $11.50 per share, in a private placement. The proceeds from the sale of the Private Placement Warrants were added to the net proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Warrants will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless.

NOTE 6. RELATED PARTY TRANSACTIONS

Founder Shares

On October 12, 2020, the Initial Stockholders purchased 7,187,500 shares (the “Founder Shares”) of the Company’s Class B common stock for an aggregate price of $25,000. The Founder Shares include an aggregate of up to 937,500 shares subject to forfeiture by the initial stockholders to the extent that the underwriter’s over-allotment is not exercised in full or in part, so that the Sponsor will collectively own, on an as-converted basis, 20% of the Company’s issued and outstanding shares after the Initial Public Offering

(assuming the Sponsor does not purchase any Public Shares in the Initial Public Offering). As a result of the underwriters’ election to fully exercise their over-allotment option, no Founder Shares are subject to forfeiture.

The Initial Stockholders have agreed, subject to certain limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier to occur of: (1) one year after the completion of a Business Combination or (B) subsequent to a Business Combination, (x) if the last reported sale price of the Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after a Business Combination, or (y) the date on which the Company completes a liquidation, merger, capital stock exchange or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of common stock for cash, securities or other property.

Promissory Note — Related Party

On October 1, 2020, certain of the Company’s directors agreed to loan the Company an aggregate of up to $300,000 to cover expenses related to the Initial Public Offering pursuant to promissory notes (the “Promissory Notes”). The Promissory Notes are non-interest bearing and are payable on the earlier of (i) September 30, 2021 and (ii) the consummation of the Initial Public Offering. As of December 31, 2020, the Company had $160,000 outstanding under the Notes. The outstanding balance under the Promissory Note of $80,000 was subsequently repaid on February 8, 2021, while the remaining $80,000 was repaid on February 10, 2021.

register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of a Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. Notwithstanding the foregoing, Cowen Investments may not exercise its demand and “piggyback” registration rights after five and seven years, respectively, after the effective date of the Initial Public Offering. The registration rights agreement does not contain liquidating damages or other cash settlement provisions resulting from delays in registering the Company’s securities. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Business Combination Marketing Agreement

The Company engaged the underwriters as an advisor in connection with a Business Combination to assist the Company in holding meetings with its stockholders to discuss the potential Business Combination and the target business’ attributes, introduce the Company to potential investors that are interested in purchasing the Company’s securities in connection with a Business Combination, provide financial advisory services to assist the Company in the Company’s efforts to obtain any stockholder approval for the Business Combination and assist the Company with its press releases and public filings in connection with the Business Combination. The Company will pay the underwriters a cash fee for such services upon the consummation of a Business Combination in an amount equal to, in the aggregate, 3.5% of the gross proceeds of Initial Public Offering.

Business Combination Agreement

On September 8, 2021, the Company, Merger Sub and Energy Vault entered into the Business Combination Agreement, pursuant to which Novus and Energy Vault will consummate the Business Combination. The Business Combination Agreement contains customary representations and warranties, covenants, closing conditions, termination fee provisions and other terms relating to the Merger and the other transactions contemplated thereby.

The Merger is to become effective by the filing of a certificate of merger with the Secretary of State of the State of Delaware, in accordance with the relevant provisions of the Delaware General Corporation Law and mutually agreed by the parties and will be effective immediately upon such filing or upon such later time as may be agreed by the parties and specified in such certificate of merger (such time, “Effective Time”). The parties will hold the Closing immediately prior to such filing of a certificate of merger, on the Closing Date.

At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Merger Sub, Energy Vault or the holders of any of Energy Vault’s securities:

Each share of Energy Vault Common Stock issued and outstanding immediately prior to the Effective Time will be cancelled and automatically converted into the right to receive the number

price of one share of the Company’s Common Stock quoted on the New York Stock Exchange or the exchange on which the shares of the Company’s Common Stock are then traded, for any 20 trading days within a 30 consecutive trading day period (as adjusted for stock splits, reverse stock splits, stock dividends, reorganizations, recapitalizations, reclassifications, combination, exchange of shares or the like).

Subscription Agreements

In connection with the execution of the Business Combination Agreement, on September 8, 2021, the Company entered into separate subscription agreements (collectively, the “Subscription Agreements”) with a number of investors (each, a “Subscriber” and collectively, the “Subscribers”), pursuant to which the Subscribers agreed to purchase, and the Company agreed to sell to the Subscribers, an aggregate of 10,000,005 shares of the Company’s Common Stock (the “PIPE Shares”), for a purchase price of $10.00 per share and an aggregate purchase price of $100,000,050 in a private placement (the “PIPE”).

The closing of the sale of the PIPE Shares pursuant to the Subscription Agreements is contingent upon, among other customary closing conditions, the concurrent consummation of the Proposed Transactions. The purpose of the PIPE is to raise additional capital for use by the combined company following the Closing.

Pursuant to the Subscription Agreements, the Company agreed that, by the later of 30 calendar days and 20 business days after the consummation of the Proposed Transactions, the Company will file with the SEC (at the Company’s sole cost and expense) a registration statement registering the resale of the PIPE Shares (the “PIPE Resale Registration Statement”), and the Company shall use its commercially reasonable efforts to have the PIPE Resale Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the 60th calendar day (or 120th calendar day if the SEC notifies the Company that it will “review” the PIPE Resale Registration Statement) following the Closing and (ii) the 10th business day after the date the Company is notified (orally or in writing, whichever is earlier) by the SEC that the PIPE Resale Registration Statement will not be “reviewed” or will not be subject to further review.

Vendor Agreements

On April 30, 2021, the Company entered into an agreement with a vendor for investment banking services related to the pending Business Combination. Specifically, the agreement relates to assisting in raising the funds as part of the PIPE financing. The agreement calls for the vendor to receive a contingent fee equal to 70% of the total placement fee paid as part of the PIPE financing which is expected to equal 5% of the gross proceeds of securities sold in the PIPE placement.

On May 21, 2021, the Company entered into an agreement with a vendor for financial advisement services related to the Business Combination. The agreement calls for the vendor to receive a contingent fee in the amount of $7,500,000 plus expenses. In addition, the agreement contains an additional contingent fee provision of 1% of the gross proceeds of any equity or equity-linked securities sold in connection with the Business Combination.

On September 13, 2021, the Company entered into an agreement with a vendor for capital market advisement services related to the Business Combination. The agreement calls for the vendor to receive a contingent fee in the amount of $500,000 upon the consummation of the Business Combination.

NOTE 8. STOCKHOLDER’S EQUITY

Preferred Stock — The Company is authorized to issue 5,000,000 shares of $0.0001 par value preferred stock. At September 30, 2021 and December 31, 2020, there were no shares of preferred stock issued or outstanding.

Class A Common Stock — The Company is authorized to issue up to 500,000,000 shares of Class A, $0.0001 par value common stock. Holders of the Company’s common stock are entitled to one vote for each share. At September 30, 2021, there were 28,750,000 shares of Class A common stock issued and outstanding which are presented as temporary equity. At December 31, 2020, there were no shares of Class A common stock issued or outstanding.

Class B Common Stock — The Company is authorized to issue up to 20,000,000 shares of Class B, $0.0001 par value common stock. Holders of the Company’s common stock are entitled to one vote for each share. At September 30, 2021 and December 31, 2020, there were 7,187,500 shares of Class B common stock issued and outstanding.

Holders of Class A common stock and Class B common stock will vote together as a single class on all other matters submitted to a vote of shareholders, except as required by law.

The shares of Class B common stock will automatically convert into shares of Class A common stock at the time of a Business Combination on a one-for-one basis (subject to adjustment). In the case that additional shares of Class A common stock, or equity-linked securities, are issued or deemed issued in excess of the amounts offered in this prospectus and related to the closing of a Business Combination, the ratio at which shares of Class B common stock shall convert into shares of Class A common stock will be adjusted (unless the holders of a majority of the outstanding shares of Class B common stock agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B common stock will equal, in the aggregate, on an as-converted basis, 20% of the sum of the total number of all shares of common stock outstanding upon completion of the Initial Public Offering plus all shares of Class A common stock and equity-linked securities issued or deemed issued in connection with a Business Combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in a Business Combination, and any private placement-equivalent warrants issued to the Sponsor or its affiliates upon conversion of loans made to the Company).

NOTE 9. FAIR VALUE MEASUREMENTS

The Company follows the guidance in ASC 820 for its financial assets and liabilities that are re-measured and reported at fair value at each reporting period, and non-financial assets and liabilities that are re-measured and reported at fair value at least annually.

The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities:

Level 1:

Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2:

Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted

F-87

TABLE OF CONTENTS

NOVUS CAPITAL CORPORATION II

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER 30, 2021
(UNAUDITED)

prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

Level 3:

Unobservable inputs based on our assessment of the assumptions that market participants would use in pricing the asset or liability.

The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis at September 30, 2021 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value.

Description	September 30, 2021			Quoted Prices in Active Markets (Level 1)			Significant Other Observable Inputs (Level 2)			Significant Other Unobservable Inputs (Level 3)
Assets:
Marketable securities held in Trust Account		$	287,509,721		$	287,509,721		$	—		$	—
Liabilities:
Warrant Liability – Public Warrants		$	10,445,833		$	10,445,833		$	—		$	—
Warrant Liability – Private Placement Warrants		$	5,683,333		$	—		$	—		$	5,683,333

Transfers to/from Levels 1, 2 and 3 are recognized at the end of the reporting period in which a change in valuation technique or methodology occurs. The estimated fair value of the Public Warrants transferred from a Level 3 measurement to a Level 1 measurement during the nine months ended September 30, 2021.

The Warrants are measured at fair value on a recurring basis. The Public Warrants were initially valued using a Modified Monte Carlo Simulation. As of September 30, 2021, the Public Warrants were valued using the instrument’s publicly listed trading price as of the balance sheet date, which is considered to be a Level 1 measurement due to the use of an observable market quote in an active market.

The Private Placement Warrants were valued using a Modified Black-Scholes Option Pricing Model, which is considered to be a Level 3 fair value measurement. The primary unobservable input utilized in determining the fair value of the Private Placement Warrants is the expected volatility of our common stock. The expected volatility of the Company’s common stock was determined based on the implied volatility of the Public Warrants.

The key inputs into the Modified Montel Carlo Simulation and the Modified Black-Scholes Option Pricing model for Warrants were as follows:

	February 8, 2021 Initial Measurement						September 30, 2021
Input	Public Warrants			Private Warrants			Private Warrants
Risk-free interest rate			0.48%			0.48%			0.98%
Expected term (years)			5.00			5.00			5.00
Expected volatility			21.0%			21.0%			17.00%
Exercise price		$	11.50		$	11.50		$	11.50
Stock Price		$	10.00		$	10.00		$	9.90

shares of Novus Class A Common Stock equal to the Exchange Ratio; all shares of Company Common Stock subject to forfeiture to or repurchase by the Company shall retain such restrictions following conversion into Novus Class A Common Stock;

(ii) all shares of Company Common Stock and Company Preferred Stock held in the treasury of the Company shall be canceled without any conversion thereof and no payment or distribution shall be made with respect thereto;

(iii) each share of Merger Sub Common Stock issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of common stock, par value $0.001 per share, of the Surviving Corporation;

(iv) each Company Option that is outstanding immediately prior to the Effective Time, whether vested or unvested, shall be assumed, converted and/or substituted by Novus into an option to purchase a number of shares of Novus Class A Common Stock (each such option, an “Exchanged Option”) equal to the product (rounded down to the nearest whole number) of (x) the number of shares of Company Common Stock subject to such Company Option immediately prior to the Effective Time and (y) the Exchange Ratio, and at an exercise price per share (rounded up to the nearest whole cent) equal to (A) the exercise price per share of such Company Option immediately prior to the Effective Time divided by (B) the Exchange Ratio; provided, however, that the exercise price and the number of shares of Novus Common Stock purchasable pursuant to the Exchanged Options shall be determined in a manner consistent with the requirements of Section 409A of the Code; provided, further, that in the case of any Exchanged Option to which Section 422 of the Code applies, the exercise price and the number of shares of Novus Common Stock purchasable pursuant to such option shall be determined in accordance with the foregoing, subject to such adjustments as are necessary in order to satisfy the requirements of Section 424(a) of the Code. Except as specifically provided above, following the Effective Time, each Exchanged Option shall continue to be governed by the same terms and conditions (including vesting and exercisability terms) as were applicable to the corresponding former Company Option immediately prior to the Effective Time;

(v) each award of Company RSUs that is outstanding immediately prior to the Effective Time shall be assumed, converted and/or substituted by Novus into an award of restricted stock units to acquire shares of Novus Class A Common Stock (each, a “Converted RSU Award”). Each Converted RSU Award will represent the right to acquire that number of shares of Novus Class A Common Stock equal to the product (rounded down to the nearest whole number) of (1) the number of shares of Company Common Stock subject to the Company RSU award immediately before the Effective Time and (2) the Exchange Ratio; provided, that, except as specifically provided above, following the Effective Time, each Converted RSU Award shall continue to be governed by the same terms and conditions (including vesting terms) as were applicable to the corresponding former Company RSU award immediately prior to the Effective Time;

(vi) each Company Restricted Share award, whether vested or unvested, shall be assumed, converted and/or substituted by Novus into a restricted stock award with respect to a number of shares of Novus Class A Common Stock (each such restricted stock award, an “Exchanged RSA”) equal to the product (rounded down to the nearest whole number) of (x) the number of shares of Company Common Stock subject to such Company Restricted Share award immediately prior to the Effective Time and (y) the Exchange Ratio, with the same terms and conditions as were applicable under such Company Restricted Share award immediately prior to the Effective Time; and

(vii) At or prior to the Effective Time, the parties and their boards, as applicable, shall adopt any resolutions and take any actions that are necessary to effectuate the treatment of the Company Options, Company RSUs and the Company Restricted Shares pursuant to this subsection, or to cause any disposition or acquisition of equity securities of Novus pursuant to this Sections 3.01(b)(iv) by each individual who is subject to the reporting requirements of Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), with respect to Novus or who will (or is reasonably expected to) become subject to such reporting requirements with respect

to Novus to be exempt under Rule 16b-3 under the Exchange Act.

By way of example and for illustrative purposes only, if the Company has 14,788,127 Company Outstanding Shares outstanding on a fully diluted basis as of the date of this Agreement, the Exchange Ratio would be approximately 6.7621157. Assuming the Company has outstanding on the date of this Agreement, 2,004,080 shares of Series C Preferred Stock (with an aggregate liquidation value of $98,251,611.91), Novus will issue an aggregate of 13,551,946 shares of Novus Common Stock at Closing, in addition to the 100,000,000 shares of Novus Common Stock to be issued at Closing. Assuming the Company has outstanding on the date of this Agreement, 2,182,524 shares of Series C Preferred Stock (with an aggregate liquidation value of $107,000,000), Novus will issue an aggregate of 14,758,620 shares of Novus Common Stock at Closing, in addition to the 100,000,000 shares of Novus Common Stock to be issued at Closing. In the event that the Company has outstanding a number of shares of Series C Preferred Stock between the amounts set forth above, the number of additional shares of Novus Common Stock that will be issued at Closing will be prorated between two amount of shares of Novus Common Stock.

SECTION 3.02 Exchange of Certificates.

(a) Exchange Agent. On the Closing Date, Novus shall deposit, or shall cause to be deposited, with a bank or trust company that shall be Continental (the “Exchange Agent”), for the benefit of the holders of Company Common Stock, for exchange in accordance with this Article III, the number of shares of Novus Common Stock sufficient to deliver the aggregate Per Share Merger Consideration payable pursuant to this Agreement (such shares of Novus Common Stock, together with any dividends or distributions with respect thereto pursuant to Section 3.02(c), being hereinafter referred to as the “Exchange Fund”).

Within two (2) Business Days (but in no event prior to the Effective Time) after the surrender to the Exchange Agent of all Certificates held by such holder for cancellation, together with a Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto and such other documents as may be required pursuant to such instructions, the holder of such Certificates shall be entitled to receive in exchange therefore, and Novus shall cause the Exchange Agent to deliver the Per Share Merger Consideration in accordance with the provisions of Section 3.01, and the Certificate so surrendered shall forthwith be cancelled. Until surrendered as contemplated by this Section 3.02, each Certificate entitled to receive the Per Share Merger Consideration in accordance with Section 3.01 shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender the Per Share Merger Consideration that such holder is entitled to receive in accordance with the provisions of Section 3.01.

(ii) Within two (2) Business Days following the Effective Time (but in no event prior to the Effective Time), Novus shall cause the Exchange Agent to deliver to each holder of Company Common Stock, as of immediately prior to the Effective Time, represented by book-entry (including

A-15

TABLE OF CONTENTS

shares of Company Common Stock resulting from the conversion of Company Preferred Stock not evidenced by Certificates described in Section 3.01(a)) the Per Share Merger Consideration in accordance with the provisions of Section 3.01, and such Company Common Stock shall forthwith be cancelled.

(c) Distributions with Respect to Unexchanged Shares of Novus Common Stock. No dividends or other distributions declared or made after the Effective Time with respect to the Novus Class A Common Stock with a record date after the Effective Time shall be paid to the holder of any surrendered Certificate with respect to the shares of Novus Class A Common Stock to be issued in exchange therefor until the holder of such Certificate shall surrender such Certificate in accordance with Section 3.02b). Subject to the effect of escheat, Tax or other applicable Laws, following surrender of any such Certificate, Novus shall pay or cause to be paid to the holder of the shares of Novus Class A Common Stock issued in exchange therefore, without interest, (i) promptly, but in any event within five (5) Business Days of such surrender, the amount of dividends or other distributions with a record date after the Effective Time and theretofore paid with respect to such shares of Novus Class A Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions, with a record date after the Effective Time but prior to surrender and a payment date occurring after surrender, payable with respect to such shares of Novus Class A Common Stock.

(d) No Further Rights in Company Common Stock. The Per Share Merger Consideration payable upon conversion of the Company Common Stock (including shares of Company Common Stock resulting from the conversion of Company Preferred Stock described in Section 3.01a)) in accordance with the terms hereof shall be deemed to have been paid and issued in full satisfaction of all rights pertaining to such Company Common Stock.

(e) Adjustments to Per Share Consideration. The Per Share Merger Consideration shall be adjusted to reflect appropriately the effect of any stock split, reverse stock split, stock dividend, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to Novus Class A Common Stock occurring on or after the date hereof and prior to the Effective Time.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Company Common Stock for one year after the Effective Time shall be delivered to Novus, upon demand, and any holders of Company Common Stock who have not theretofore complied with this Section 3.02 shall thereafter look only to Novus for the Per Share Merger Consideration. Any portion of the Exchange Fund remaining unclaimed by holders of Company Common Stock as of a date which is immediately prior to such time as such amounts would otherwise escheat to or become property of any government entity shall, to the extent permitted by applicable law, become the property of Novus free and clear of any claims or interest of any person previously entitled thereto.

(g) No Liability. None of the Exchange Agent, Novus or the Surviving Corporation shall be liable to any holder of Company Common Stock (including shares of Company Common Stock resulting from the conversion of Company Preferred Stock described in Section 3.01a)) for any Novus Class A Common Stock (or dividends or distributions with respect thereto) or cash delivered to a public official pursuant to any abandoned property, escheat or similar Law in accordance with this Section 3.02.

(h) Withholding. Notwithstanding anything in this Agreement to the contrary, each of the Company, the Surviving Corporation, Merger Sub, Novus, and the Exchange Agent shall be entitled to deduct and withhold from amounts otherwise payable pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under the United States Internal Revenue Code of 1986, as amended (the “Code”) or any provision of state, local or non-U.S. Tax Law.

Any stockholder of the Company who fails to perfect or who effectively withdraws or otherwise loses his, her or its rights to appraisal of such shares of Company Common Stock under Section 262 of the DGCL shall thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the Per Share Merger Consideration, without any interest thereon, upon surrender, if applicable, in the manner provided in Section 3.02(b), of the Certificate or Certificates that formerly evidenced such shares of Company Common Stock or Company Preferred Stock (as the case may be).

in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the Transactions be consummated as originally contemplated to the fullest extent possible.

SECTION 10.04 Entire Agreement; Assignment. This Agreement and the Ancillary Agreements constitute the entire agreement among the parties with respect to the subject matter hereof and supersede, except as set forth in Section 7.04(b), all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof, except for the Confidentiality Agreement. This Agreement shall not be assigned (whether pursuant to a merger, by operation of law or otherwise) by any party without the prior express written consent of the other parties hereto.

SECTION 10.05 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, other than Section 7.08 (which is intended to be for the benefit of the persons covered thereby and may be enforced by such persons).

SECTION 10.06 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware applicable to contracts executed in and to be performed in that State. All legal actions and proceedings arising out of or relating to this Agreement shall be heard and determined exclusively in any Delaware Chancery Court; provided, that if jurisdiction is not then available in the Delaware Chancery Court, then any such legal Action may be brought in any federal court located in the State of Delaware or any other Delaware state court. The parties hereto hereby (a) irrevocably submit to the exclusive jurisdiction of the aforesaid courts for themselves and with respect to their respective properties for the purpose of any Action arising out of or relating to this Agreement brought by any party hereto, and (b) agree not to commence any Action relating thereto except in the courts described above in Delaware, other than Actions in any court of competent jurisdiction to enforce any judgment, decree or award rendered by any such court in Delaware as described herein. Each of the parties further agrees that notice as provided herein shall constitute sufficient service of process and the parties further waive any argument that such service is insufficient. Each of the parties hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any Action arising out of or relating to this Agreement or the transactions contemplated hereby, (a) any claim that it is not personally subject to the jurisdiction of the courts in Delaware as described herein for any reason, (b) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (c) that (i) the Action in any such court is brought in an inconvenient forum, (ii) the venue of such Action is improper or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

Each of the parties hereto (a) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce that foregoing waiver and (b) acknowledges that it and the other hereto have been induced to enter into this Agreement and the Transactions, as applicable, by, among other things, the mutual waivers and certifications in this Section 10.07.

SECTION 10.08 Headings. The descriptive headings contained in this Agreement are included for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement.

SECTION 10.09 Counterparts. This Agreement may be executed and delivered (including by facsimile or portable document format (pdf) transmission) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

SECTION 10.10 Specific Performance.

(a) The parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or

A-61

TABLE OF CONTENTS

were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to enforce specifically the performance of the terms and provisions of this Agreement, including the right of a party to cause the other parties to consummate the Transactions. It is agreed that the parties are entitled to enforce specifically the performance of terms and provisions of this Agreement, without proof of actual damages (and each such party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at law or in equity. Such action shall be brought in the Court of Chancery of the State of Delaware or, if that court does not have jurisdiction, any court of the United States located in the State of Delaware. The parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to any applicable Law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for any such breach. Each of the parties hereby further waives any defense in any action for specific performance that a remedy at law would be adequate.

(b) The parties further agree that the Company would suffer irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the parties to the Subscription Agreements do not perform their obligations under the provisions of such Subscription Agreements (including failing to take such actions as are required of them thereunder to consummate the Private Placement) in accordance with its specified terms or otherwise breach such provisions. The parties acknowledge and agree that (i) if the parties to the Subscription Agreements do not perform their obligations under the provisions of the Subscription Agreements, then (1) the Company shall have the right to either (at the Company’s election) (I) on behalf of Novus, seek an injunction, specific performance, or other equitable relief, to prevent breaches of such Subscription Agreements and to enforce specifically the terms and provisions thereof, without proof of damages or (II) seek an injunction, specific performance, or other equitable relief, to cause Novus to prevent breaches of the Subscription Agreements and to cause Novus to enforce specifically the terms and provisions thereof, without proof of damages, in each case of the foregoing clauses (I) and (II), prior to the valid termination of this Agreement in accordance with Section 9.01, this being in addition to any other remedy to which it is entitled under this Agreement, and (2) Novus shall not object or otherwise oppose any Action pursuant to which the Company is exercising its rights pursuant to the foregoing clause (1), and (ii) the right of specific enforcement is an integral part of the Transactions and without that right, none of the parties would have entered into this Agreement.

(c) Notwithstanding anything to the contrary in this Agreement, if prior to the Outside Date any party initiates an Action to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, then the Outside Date will be automatically extended by: (A) the amount of time during which such Action is pending plus 20 Business Days; or (B) such other time period established by the court presiding over such Action.

SECTION 10.11 No Recourse. All claims, obligations, liabilities, or causes of action (whether in contract or in tort, in law or in equity, or granted by statute) that may be based upon, in respect of, arise under, out or by reason of, be connected with, or relate in any manner to this Agreement, or the negotiation, execution, or performance of this Agreement (including any representation or warranty made in, in connection with, or as an inducement to, this Agreement), may be made only against (and such representations and warranties are those solely of) the persons that are expressly identified as parties in the preamble to this Agreement (the “Contracting Parties”) except as set forth in this Section 10.11. No person who is not a Contracting Party, including any current, former or future director, officer, employee, incorporator, member, partner, manager, stockholder, affiliate, agent, attorney, Representative or assignee of, and any financial advisor or lender to, any Contracting Party, or any current, former or future director, officer, employee, incorporator, member, partner, manager, stockholder, affiliate, agent, attorney, Representative or assignee of, and any financial advisor or lender to, any of the foregoing (collectively, the “Nonparty Affiliates”), shall have any liability (whether in contract or in tort, in law or in equity, or granted by statute) for any claims, causes of action, obligations, or liabilities arising under, out of, in connection with, or related in any manner to this Agreement or based on, in respect of, or by reason of this Agreement or its negotiation, execution, performance, or breach, except with respect to willful misconduct or common law fraud against the person who committed such willful misconduct or common law fraud, and, to the maximum extent permitted by

the New Holders or the Original Holders being entered into as of the Effective Date, (i) New Holders holding at least 20% of the then-outstanding number of Registrable Securities held by all New Holders (such New Holders, the “Demanding New Holders”) or (ii) Original Holders holding at least a majority in interest of the then-outstanding number of Registrable Securities held by all Original Holders (such Original Holders, the “Demanding Original Holders”), may make a written demand for Registration of all or part of their Registrable Securities on Form S-3 (“Form S-3”) (or, if Form S-3 is not available to be used by the Company at such time, on Form S-1 or another appropriate form permitting Registration of such Registrable Securities for resale by such Demanding Holders), which written demand shall describe the amount, not to be less than $25 million, and type of securities to be included in such Registration and the intended method(s) of distribution thereof (such written demand a “Demand Registration”).

2.1.2 Effective Registration. Notwithstanding the provisions of Subsection 2.1.1 above or any other part of this Agreement, a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (i) the Registration Statement filed with the Commission with respect to a Registration pursuant to a Demand Registration has been declared effective by the Commission and (ii) the Company has complied with all of its obligations under this Agreement with respect thereto; provided, further, that if, after such Registration Statement has been declared effective, an offering of Registrable Securities in a Registration pursuant to a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission, federal or state court or any other governmental agency the Registration Statement with respect to such Registration shall be deemed not to have been declared effective, unless and until, (y) such stop order or injunction is removed, rescinded or otherwise terminated, and (z) a majority-in-interest of the Demanding Holders initiating such Demand Registration thereafter affirmatively elect to continue with such Registration and accordingly notify the Company in writing, but in no event later than five (5) days, of such election; provided, further, that the Company shall not be obligated or required to file another Registration Statement until the Registration Statement that has been previously filed with respect to a Registration pursuant to a Demand Registration becomes effective or is subsequently terminated.

Demanding Holders and the Demand Requesting Holders (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Holders and the Demand Requesting Holders (if any) desire to sell, taken together with all other Common Stock or other equity securities that the Company desires to sell and the Common Stock, if any, as to which a Registration has been requested pursuant to separate written contractual piggy-back registration rights held by any other stockholders who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company shall include in such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Demanding Holders and the Demand Requesting Holders (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Holder and Demand Requesting Holder (if any) has requested be included in such Underwritten Registration and the aggregate number of Registrable Securities that the Demanding Holders and Demand Requesting Holders have requested be included in such Underwritten Registration) that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), Common Stock or other equity securities of other persons or entities that the Company is obligated to register in a Registration pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities.

2.1.5 Demand Registration Withdrawal. A majority-in-interest of the Demanding New Holders, in the case of a Registration under subsection 2.1.1 initiated by the New Holders, or a majority-in-interest of the Demand Requesting Holders (if any), pursuant to a Registration under subsection 2.2.1, shall have the right to withdraw from a Registration pursuant to such Demand Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to the Registration of their Registrable Securities pursuant to such Demand Registration. If a majority-in-interest of the Demanding Holders initiating a Demand Registration or a majority-in-interest of the Demand Requesting Holders (if any), withdraws from a proposed offering pursuant to this Section 2.1.5, then such registration shall not count as a Demand Registration provided for in Section 2.1. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a Registration pursuant to a Demand Registration prior to its withdrawal under this subsection 2.1.5.

Section 2.2 Piggyback Registration.

2.2.1 Piggyback Rights. If, at any time on or after the date hereof, the Company proposes to file a Registration Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the account of stockholders of the Company (or by the Company and by the stockholders of the Company including, without limitation, pursuant to Section 2.1 hereof), other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company, (iv) for a dividend reinvestment plan, (v) on Form S-4 filed in connection with the Business Combination or (vi) filed pursuant to Section 2.3 hereof, then the Company shall give written notice of such proposed filing to all of the Holders of Registrable Securities then outstanding as soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement, which notice shall (A) describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such offering, and (B) offer to all of the Holders of Registrable Securities the opportunity to register the sale of such number of Registrable Securities as such Holders may request in writing within five (5) days after receipt of such written notice (such Registration a “Piggyback Registration”). The Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and shall use its best efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable Securities requested by the Holders pursuant to this

TABLE OF CONTENTS

Subsection 2.2.1 to be included in a Piggyback Registration on the same terms and conditions as any similar securities of the Company included in such Registration and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this Subsection 2.2.1 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the Company.

2.2.2 Reduction of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Registration that is to be a Piggyback Registration, in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of shares of Common Stock that the Company desires to sell, taken together with (i) the shares of Common Stock, if any, as to which Registration has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant to Section 2.2 hereof, and (iii) the shares of Common Stock, if any, as to which Registration has been requested pursuant to separate written contractual piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Number of Securities, then:

(i) If the Registration is undertaken for the Company’s account, the Company shall include in any such Registration (A) first, Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to Subsection 2.2.1 hereof, pro rata, based on the respective number of Registrable Securities that each Holder has so requested, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), Common Stock, if any, as to which Registration has been requested pursuant to written contractual piggy-back registration rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities; and

(ii) If the Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the Company shall include in any such Registration (A) first, Common Stock or other equity securities, if any, of such requesting persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection 2.2.1, pro rata based on the respective number of Registrable Securities that each Holder has requested be included in such Underwritten Registration and the aggregate number of Registrable Securities that the Holders have requested to be included in such Underwritten Registration, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), Common Stock or other equity securities for the account of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number of Securities.

2.2.3 Piggyback Registration Withdrawal. Any Holder of Registrable Securities shall have the right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Piggyback Registration. The Company (whether on its own good faith determination or as the result of a request for withdrawal by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this subsection 2.2.3.

2.2.4 Unlimited Piggyback Registration Rights. For purposes of clarity, any Registration effected pursuant to Section 2.2 hereof shall not be counted as a Registration pursuant to a Demand Registration effected under Section 2.1 hereof.

Section 2.3 Resale Shelf Registration Rights

2.3.1 Registration Statement Covering Resale of Registrable Securities. The Company shall prepare and file or cause to be prepared and filed with the Commission, no later than the later of (i) thirty (30) calendar days following the closing of the Business Combination and (ii) twenty (20) Business Days following the closing of the Business Combination, a Registration Statement for an offering to be made on a delayed or continuous basis pursuant to Rule 415 of the Securities Act or any successor thereto registering the resale from time to time by Holders of all of the Registrable Securities held by Holders (the “Resale Shelf Registration Statement”). The Resale Shelf Registration Statement shall be on Form S-1. The Company shall use commercially reasonable efforts to cause the Resale Shelf Registration Statement to be declared effective as soon as practicable after filing, but no later than the earlier of (i) the 60th calendar day (or 120th calendar day if the Commission notifies the Company that it will “review” the Registration Statement) following the closing of the Business Combination and (ii) the tenth Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Resale Shelf Registration Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Deadline”). Once effective, the Company shall use commercially reasonable efforts to keep the Resale Shelf Registration Statement continuously effective and to be supplemented and amended to the extent necessary to ensure that such Registration Statement is available or, if not available, to ensure that another Registration Statement is available, under the Securities Act at all times until all Registrable Securities and other securities covered by such Registration Statement have been disposed of in accordance with the intended method(s) of distribution set forth in such Registration Statement or have ceased to be Registrable Securities. The Registration Statement filed with the Commission pursuant to this subsection 2.3.1 shall contain a prospectus in such form as to permit any Holder to sell such Registrable Securities pursuant to Rule 415 under the Securities Act (or any successor or similar provision adopted by the Commission then in effect) at any time beginning on the effective date for such Registration Statement (subject to the restrictions provided in the Sponsor Restricted Stock Agreement and the Lock-up Agreement between the Company and the relevant Holders, each being entered into as of the date hereof), and shall provide that such Registrable Securities may be sold pursuant to any method or combination of methods legally available to, and requested by, the Holders. Promptly following the date upon which the Company becomes eligible to use a Registration Statement on Form S-3, the Company shall file a post-effective amendment on Form S-3 to the Resale Shelf Registration Statement (an “S-3 Conversion”).

2.3.2 Notification and Distribution of Materials. The Company shall notify the Holders in writing of the effectiveness of the Resale Shelf Registration Statement as soon as practicable, and in any event within one (1) Business Day after the Resale Shelf Registration Statement becomes effective, and shall furnish to them, without charge, such number of copies of the Resale Shelf Registration Statement (including any amendments, supplements and exhibits), the Prospectus contained therein (including each preliminary prospectus and all related amendments and supplements) and any documents incorporated by reference in the Resale Shelf Registration Statement or such other documents as the Holders may reasonably request in order to facilitate the sale of the Registrable Securities in the manner described in the Resale Shelf Registration Statement.

2.3.3 Amendments and Supplements. Subject to the provisions of Section 2.3.1 above, the Company shall promptly prepare and file with the Commission from time to time such amendments and supplements to the Resale Shelf Registration Statement and Prospectus used in connection therewith as may be necessary to keep the Resale Shelf Registration Statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all the Registrable Securities. If any Resale Shelf Registration Statement filed pursuant to Section 2.3.1 is filed on Form S-3 and thereafter the Company becomes ineligible to use Form S-3 for secondary sales, the Company shall promptly notify the Holders of such ineligibility and use its best efforts to file a shelf registration on an appropriate form as promptly as practicable to replace the shelf registration statement on Form S-3 and have the such replacement Resale Shelf Registration Statement declared effective as promptly as practicable and to cause such replacement Resale Shelf Registration Statement to remain effective, and to be supplemented and amended to the extent

A-72

TABLE OF CONTENTS

necessary to ensure that such Resale Shelf Registration Statement is available or, if not available, that another Resale Shelf Registration Statement is available, for the resale of all the Registrable Securities held by the Holders until all such Registrable Securities have ceased to be Registrable Securities; provided, however, that at any time the Company once again becomes eligible to use Form S-3, the Company shall cause such replacement Resale Shelf Registration Statement to be amended, or shall file a new replacement Resale Shelf Registration Statement, such that the Resale Shelf Registration Statement is once again on Form S-3.

2.3.4 Notwithstanding the registration obligations set forth in this Section 2.3, in the event the Commission informs the Company that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform each of the holders thereof and use its reasonable efforts to file amendments to the Resale Shelf Registration Statement as required by the Commission and/or (ii) withdraw the Resale Shelf Registration Statement and file a new registration statement (a “New Registration Statement”), on Form S-3, or if Form S-3 is not then available to the Company for such registration statement, on such other form available to register for resale the Registrable Securities as a secondary offering; provided, however, that prior to filing such amendment or New Registration Statement, the Company shall use its reasonable efforts to advocate with the Commission for the registration of all of the Registrable Securities in accordance with any publicly-available written or oral guidance, comments, requirements or requests of the Commission staff (the “SEC Guidance”), including without limitation, the Manual of Publicly Available Telephone Interpretations D.29. Notwithstanding any other provision of this Agreement, if any SEC Guidance sets forth a limitation of the number of Registrable Securities permitted to be registered on a particular Registration Statement as a secondary offering (and notwithstanding that the Company used diligent efforts to advocate with the Commission for the registration of all or a greater number of Registrable Securities), unless otherwise directed in writing by a Holder as to its Registrable Securities, the number of Registrable Securities to be registered on such Registration Statement will be reduced in order to include first, the number of shares of Common Stock included in the Resale Shelf Registration Statement that are held by PIPE Investors (as defined in the Business Combination Agreement), and second, the Registrable Securities under this Agreement, on a pro rata basis based on the total number of Registrable Securities held by the Holders, subject to a determination by the Commission that certain Holders must be reduced first based on the number of Registrable Securities held by such Holders. In the event the Company amends the Resale Shelf Registration Statement or files a New Registration Statement, as the case may be, under clauses (i) or (ii) above, the Company will use its reasonable efforts to file with the Commission, as promptly as allowed by Commission or SEC Guidance provided to the Company or to registrants of securities in general, one or more registration statements on Form S-3 or such other form available to register for resale those Registrable Securities that were not registered for resale on the Resale Shelf Registration Statement, as amended, or the New Registration Statement.

2.3.5 Registrations effected pursuant to this Section 2.3 shall not be counted as Demand Registrations effected pursuant to Section 2.2.

Section 2.4 Restrictions on Registration Rights. If (A) during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company initiated Registration and provided that the Company continues to actively employ, in good faith, all reasonable efforts to cause the applicable Registration Statement to become effective; (B) the Holders have requested an Underwritten Registration and the Company and the Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer; or (C) in the good faith judgment of the Board such Registration would be materially detrimental to the Company and the Board concludes as a result that it is essential to defer the filing of such Registration Statement at such time, then in each case the Company shall furnish to such Holders a certificate signed by the Chairman of the Board stating that in the good faith judgment of the Board it would be materially detrimental to the Company for such Registration Statement to be filed in the near future and that it is therefore essential to defer the filing of such Registration Statement. In such event, the Company shall have the right to defer a filing pursuant to Section 2.1 for the shortest period of time determined in good faith by the Company to be necessary for such purpose, but in any event no longer than a period of more than thirty (30) days.

Section 3.4 Suspension of Sales. Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until he, she or it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until he, she or it is advised in writing by the Company that the use of the Prospectus may be resumed. Notwithstanding anything to the contrary in this Agreement, the Company shall be entitled to delay or postpone the filing or effectiveness of a Registration Statement, and from time to time to require the Holders not to sell under a Registration Statement or to suspend the effectiveness thereof, if the negotiation or consummation of a transaction by the Company or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event the Board reasonably believes would require additional disclosure by the Company in the Registration Statement of material information that the Company has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of the Board to cause the Registration Statement to fail to comply with applicable disclosure requirements (each such circumstance, a “Suspension Event”); provided, however, that the Company may not delay or suspend a Registration Statement for the shortest period of time, but in no event more than sixty (60) days, determined in good faith by the Company to be necessary for such purpose. Upon receipt of any written notice from the Company of the happening of any Suspension Event during the period that a Registration Statement is effective or if as a result of a Suspension Event a Registration Statement or related prospectus contains any Misstatement, the Holders agree that (i) they will immediately discontinue offers and sales of the Shares under such Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until the Holders receive copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare) that corrects the Misstatements referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by the Company that it may resume such offers and sales, and (ii) they will maintain the confidentiality of any information included in such written notice delivered by the Company unless otherwise required by law or subpoena. If so directed by the Company, the Holders will deliver to the Company or, in each Holder’s sole discretion destroy, all copies of the prospectus covering the Shares in such Holder’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Shares shall not apply (i) to the extent the Holder is required to retain a copy of such prospectus (a) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (b) in accordance with a bona fide pre-existing document retention policy or (ii) to copies stored electronically on archival servers as a result of automatic data back-up.

Section 3.5 Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings. The Company further covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell shares of Common Stock held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter by the Commission), including providing any legal opinions. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

Section 3.6 Limitations on Registration Rights. From and after the date of this Agreement, other than the registration rights granted in subscription agreements with the PIPE Investors (as defined in the Business Combination Agreement), the Company shall not, without the prior written consent of holders of a majority of the Registrable Securities then outstanding, enter into any agreement with any holder or prospective holder of any securities of the Company that would provide to such holder registration rights on a basis more favorable than the registration rights granted to the Holders herein.

INDEMNIFICATION AND CONTRIBUTION

Section 4.1 Indemnification

4.1.1 The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors and agents and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including reasonable attorneys’ fees) caused by any actual or alleged Misstatement, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein.

4.1.2 In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify the Company, its directors and officers and agents and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any actual or alleged Misstatement, but only to the extent that such actual or alleged Misstatement is made in reliance on and in conformity with any information or affidavit so furnished in writing by or on behalf of such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement.

4.1.3 Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, not to be unreasonably withheld or delayed, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

4.1.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.

4.1.5 If the indemnification provided under Section 4.1 hereof from the indemnifying party is held by a court of competent jurisdiction to be unavailable to an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any actual or alleged Misstatement,

A-77

was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this subsection 4.1.5 shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in subsections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this subsection 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this subsection 4.1.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this subsection 4.1.5 from any person who was not guilty of such fraudulent misrepresentation.

Re: Lock-Up Agreement

Ladies and Gentlemen:

This letter (this “Letter Agreement”) is being delivered to you in accordance with the Business Combination Agreement and Plan of Reorganization (the “BCA”) entered into by and among Novus Capital Corporation II, a Delaware corporation (the “Company”), NCCII Merger Corp., a Delaware corporation (“Merger Sub”) and Energy Vault, Inc., a Delaware corporation (“EV”), pursuant to which, among other things, Merger Sub will be merged with and into EV on the date hereof (the “Merger”), with EV surviving the Merger as a wholly owned subsidiary of the Company.

In order to induce the Company to proceed with the Merger and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned (the “Securityholder”) hereby agrees with the Company as follows:

Subject to the exceptions set forth herein, the Securityholder agrees not to, without the prior written consent of the Board of Directors of the Company, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the Securities and Exchange Commission promulgated thereunder, any shares of Class A Common Stock, par value $0.0001 per share, of the Company (“Common Stock”) held by it immediately after the effective time of the Merger, any shares of Common Stock issuable upon the exercise of options to purchase shares of Common Stock held by it immediately after the effective time of the Merger, or any securities convertible into or exercisable or exchangeable for Common Stock held by it immediately after the effective time of the Merger (the “Lock-up Shares”), (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any of the Lock-up Shares, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise or (iii) publicly announce any intention to effect any transaction specified in clause (i) or (ii) (the actions specified in clauses (i)-(iii), collectively, “Transfer”) until 365 days after the closing date of the Merger (the “Lock-Up Period”), subject to the early release provisions set forth in Section 3 below in respect of 50% of the Lock-up Shares; provided, however, that if any party who enters into a letter agreement relating to the subject matter hereof as contemplated by the BCA (each, a “Lock-Up Stockholder”) on terms and conditions that are less restrictive than those agreed to herein (or such terms and conditions are subsequently relaxed including as a result of a modification, waiver or amendment), the less restrictive terms and conditions in such letter agreement with such Lock-Up Stockholder shall apply to the Securityholder.

The restrictions set forth in paragraph 1 shall not apply to:

(i)

in the case of an entity, Transfers (A) to another entity that is an affiliate (as defined in Rule 405 promulgated under the Securities Act of 1933, as amended) of the undersigned, or to any investment fund or other entity controlling, controlled by, managing or managed by or under common control with the undersigned or affiliates of the undersigned or who shares a common investment advisor with the undersigned or (B) as part of a distribution or transfer to direct or indirect members, general partners, limited partners or shareholders of the undersigned, or each of their employees or officers;

(ii)

in the case of an individual, Transfers by bona fide gift to members of the individual’s immediate family (as defined below) or to a trust, the beneficiary of which is a member of one of the individual’s immediate family, an affiliate of such person or to a charitable organization;

A-83

TABLE OF CONTENTS

(iii)

in the case of an individual, Transfers by virtue of laws of descent and distribution upon death of the individual;

(iv)

in the case of an individual, Transfers by operation of law or pursuant to a court order, such as a qualified domestic relations order, divorce decree or separation agreement;

(v)

in the case of an individual, Transfers to a partnership, limited liability company or other entity of which the undersigned and/or the immediate family (as defined below) of the undersigned are the legal and beneficial owner of all of the outstanding equity securities or similar interests;

(vi)

in the case of an entity that is a trust, Transfers to a beneficiary of the trust or to the estate of a beneficiary of such trust;

(vii)

in the case of an entity, Transfers by virtue of the laws of the state of the entity’s organization and the entity’s organizational documents upon dissolution of the entity;

(viii)

Transfers of any shares of Common Stock or other securities acquired as part of the Private Placements with PIPE Investors (each as defined in the BCA) or issued in exchange for, or on conversion or exercise of, any securities issued as part of the Private Placements with PIPE Investors;

(ix)

Transfers of shares of Common Stock or other securities convertible into or exercisable or exchangeable for Common Stock acquired in open market transactions after the effective time of the Merger

(x)

the exercise of stock options or warrants to purchase shares of Common Stock or the vesting of stock awards or restricted stock unit awards of Common Stock, it being understood that all such shares of Common Stock received by the undersigned upon such exercise, vesting or transfer will remain subject to the restrictions of this Letter Agreement during the Lock-Up Period, and (x) any related transfer of shares of Common Stock to the Company in connection therewith (1) deemed to occur upon the “cashless” or “net” exercise of such options or warrants or (2) for the purpose of paying the exercise price of such options or warrants or for paying taxes due as a result of the exercise of such options or warrants, the vesting of such options, warrants or restricted stock unit awards, or as a result of the vesting of such shares of Common Stock; (y) solely with respect to shares of Common Stock underlying the restricted stock units set forth on Schedule A hereto, any related sale of shares of Common Stock solely to cover the tax withholding liability related to such vesting of restricted stock unit awards through a broker in accordance with the terms of the applicable equity incentive plan or arrangement approved by the Company’s Board of Directors;

(xi)

Transfers to the Company pursuant to any contractual arrangement in effect at the effective time of the Merger that provides for the repurchase by the Company or forfeiture of Common Stock or other securities convertible into or exercisable or exchangeable for Common Stock in connection with the termination of the Securityholder’s service to the Company;

(xii)

the entry, by the Securityholder, at any time after the effective time of the Merger, of any trading plan providing for the sale of shares of Common Stock by the Securityholder, which trading plan meets the requirements of Rule 10b5-1(c) under the Exchange Act (as may be amended from time to time), provided, however, that such plan does not provide for, or permit, the sale of any shares of Common Stock during the Lock-Up Period and no public announcement or filing is voluntarily made or required regarding such plan during the Lock-Up Period;

(xiii)

transactions in the event of completion of a liquidation, merger, stock exchange or other similar transaction which results in all of the Company’s securityholders having the right to exchange their shares of Common Stock for cash, securities or other property;

(xiv)

transactions to satisfy any U.S. federal, state, or local income tax obligations of the

A-84

TABLE OF CONTENTS

Securityholder (or its direct or indirect owners) arising from a change in the U.S. Internal Revenue Code of 1986, as amended (the “Code”), or the U.S. Treasury Regulations promulgated thereunder (the “Regulations”) after the date on which the BCA was executed by the parties, and such change prevents the Merger from qualifying as a “reorganization” pursuant to Section 368 of the Code (and the Merger does not qualify for similar tax-free treatment pursuant to any successor or other provision of the Code or Regulations taking into account such changes), in each case solely and to the extent necessary to cover any tax liability as a direct result of the transaction; and

(xv)

the creation of any charge, lien, mortgage, pledge or other security interest or posting as collateral of any Common Stock of the Company in connection with a bona fide loan transaction provided that the Lock-Up Shares transferred in connection with enforcement of such loan transaction remain subject to the terms of this letter and any lender transferee agrees in writing to be bound by the restrictions set forth herein.

provided, however, that (A) in the case of clauses (i) through (vii) and clause (xiii), these permitted transferees must enter into a written agreement, in substantially the form of this Letter Agreement (it being understood that any references to “immediate family” in the agreement executed by such transferee shall expressly refer only to the immediate family of the Securityholder and not to the immediate family of the transferee), agreeing to be bound by these Transfer restrictions. For purposes of this agreement, “immediate family” shall mean a spouse, domestic partner, child (including by adoption), father, mother, brother or sister of the undersigned, and lineal descendant (including by adoption) of the undersigned or of any of the foregoing persons; and “affiliate” shall have the meaning set forth in Rule 405 under the Securities Act of 1933, as amended; and

provided, further, that with respect to the Securityholders which were securityholders of Novus prior to the closing date of the Merger, the Lock-up Shares shall only include those shares of Common Stock that were purchased or acquired by the Securityholder as part of the initial 6,468,750 founders shares of the Company (after giving effect to the forfeiture of 718,750 founder shares), 5,166,666 warrants held by the Securityholders (the “Founder Warrants”) and the shares of Common Stock issuable upon the exercise of the Founder Warrants, the number of which is set forth on the signature page hereto.

With respect to 50% of the Lock-up Shares (half of which may be Restricted Shares, as defined in the Sponsor Restricted Stock Agreement by and among the Company, stockholders of the Company identified therein and EV) (the “Early Release Shares”), the Lock-Up Period shall terminate upon 180 days after the closing date of the Merger. With respect to the shares held by the undersigned that are not Early Release Shares, the Lock-Up Period shall terminate upon the earlier of (i) 365 days after the closing date of the Merger or (ii) the closing of a sale, merger, liquidation, or exchange offer transaction after the closing date of the Merger. With respect to the Founder Warrants and the shares of Common Stock issuable upon exercise of the Founder Warrants, the Lock-Up Period shall terminate 180 days after the closing date of the Merger.

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described therein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.

This Letter Agreement constitutes the entire agreement and understanding of the parties hereto in respect of the subject matter hereof and supersedes all prior understandings, agreements or representations by or among the parties hereto, written or oral, to the extent they relate in any way to the subject matter hereof or the transactions contemplated hereby. This Letter Agreement may not be changed, amended, modified or waived (other than to correct a typographical error) as to any particular provision, except by a written instrument executed by (i) the undersigned Securityholder, (ii) the Company and (iii) the Novus’s designee to the Board of Directors of the Company listed on Exhibit H to the BCA or, if such person is not serving as a Director of the Company, Robert J. Laikin or Larry Paulson.

No party hereto may assign either this Letter Agreement or any of its rights, interests or obligations

A-85

TABLE OF CONTENTS

hereunder without the prior written consent of the other party. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not operate to transfer or assign any interest or title to the purported assignee. This Letter Agreement shall be binding on the Securityholder and each of its respective successors, heirs and assigns and permitted transferees.

This letter shall only be binding upon the undersigned if all individuals who are officers and directors of EV, immediately prior to the effective time of the merger and holders of at least one percent (1%) or more of the aggregate capital stock of EV outstanding immediately prior to the effective time (together with the officers and directors of EV as of immediately prior to the effective time of the merger, the “EV Release Parties”) enter into letters with substantially identical terms and such agreements remain in full force and effect for the same duration as this letter (or any obligations are released on a pro rata basis as between all signatories of such letters). In the event that a release is granted to any such EV Release Party, who is a party to a lock-up agreement relating to the restrictions set forth above, a number of shares of Common Stock held by the undersigned shall be immediately, fully and irrevocably released in the same manner and on the same terms from any remaining restrictions set forth above on a pro rata basis (calculated based on the percentage of ownership held by the EV Release Party of capital stock of EV outstanding as of immediately prior to the effective time of the merger and, for the avoidance of doubt, without regard to shares sold in the Private Placements to the PIPE Investors) and the Company shall notify the undersigned of any such requested release within two (2) business days of such granted request. Notwithstanding the foregoing, the provisions of the previous sentence will not apply in the case of any secondary underwritten public offering of shares of Common Stock (including a secondary underwritten public offering with a primary component).

This Letter Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Delaware, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The parties hereto (i) all agree that any action, proceeding, claim or dispute arising out of, or relating in any way to, this Letter Agreement shall be brought and enforced in the Delaware Chancery Court, and irrevocably submit to such jurisdiction and venue, which jurisdiction and venue shall be exclusive and (ii) waive any objection to such exclusive jurisdiction and venue or that such courts represent an inconvenient forum.

This Letter Agreement shall terminate upon the earlier to occur of (i) the termination of the Lock-up Period, as provided herein, and (ii) the termination of the BCA.

This SPONSOR SUPPORT AGREEMENT, dated as of September 8, 2021 (this “Agreement”), is entered into by and among Novus Capital Corporation II, a Delaware corporation (“Novus”), Energy Vault, Inc., a Delaware corporation (the “Company”), and certain Persons whose names appear on the signature pages of this Agreement (each, a “Stockholder” and, collectively, the “Stockholders”), in each case, solely in such Stockholder’s capacity as a Stockholder (and not in any other capacity).

WHEREAS, Novus, NCCII Merger Corp., a Delaware corporation and wholly owned subsidiary of Novus (“Merger Sub”), and the Company propose to enter into, simultaneously herewith, a business combination agreement a copy of which has been made available to the Stockholders (the “BCA”; terms used but not defined in this Agreement shall have the meanings ascribed to them in the BCA), which provides, among other things, that, upon the terms and subject to the conditions thereof, Merger Sub will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Novus; and

WHEREAS, as of the date hereof, each Stockholder owns of record and/or beneficially the number of shares of Novus Common Stock as set forth opposite such Stockholder’s name on Exhibit A hereto (all such shares of Novus Common Stock and any shares of Novus Common Stock of which ownership of record or the power to vote or dispose is hereafter acquired by the Stockholders prior to the termination of this Agreement being referred to herein as the “Shares”; provided however with respect to NCCII Co-Invest LLC, the term “Shares” shall mean only the shares of Novus Class B Common Stock held by such holder.)

NOW, THEREFORE, in consideration of the foregoing and of the mutual covenants and agreements contained herein, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

1. Agreement to Vote. Each Stockholder, by this Agreement, with respect to his, her or its Shares, severally and not jointly, (unless this Agreement shall have been terminated in accordance with Section 9) hereby agrees to vote (or cause to be voted), in person or by proxy, at any meeting of the stockholders of Novus, all of such Stockholder’s Shares held by such Stockholder at such time (a) in favor of (1) the approval and adoption of the BCA and approval of the Merger and all other transactions contemplated by the BCA, (2) the approval of the issuance of Novus Common Stock as contemplated by the BCA and the Subscription Agreements, (3) the approval and adoption of the second amended and restated Certificate of Incorporation of the Surviving Corporation as set forth on Exhibit E of the BCA, (4) the approval and adoption of an equity incentive plan, as set forth in Section 7.01 and Section 7.07 of the BCA, and (5) any other action, proposal that the Company and Novus deem necessary to effect the Transactions (collectively, the “Novus Proposals”) and (b) against any action, agreement or transaction or proposal that would reasonably be expected to result in the failure of the Transactions from being consummated. Each Stockholder acknowledges that a copy of the BCA has been made available to such Stockholder.

2. Redemption. Unless this Agreement shall have been terminated in accordance with Section 9, each Stockholder, severally and not jointly, hereby agrees that such Stockholder shall waive any and all Redemption Rights with respect to the Novus Proposals and shall not elect to cause Novus to redeem any Shares beneficially owned or owned of record by such Stockholder in connection with the Novus Proposals. Each Stockholder hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Account with respect to the shares of Novus Common Stock owned by the Stockholder.

Unless this Agreement shall have been terminated in accordance with Section 9, each Stockholder, severally and not jointly, agrees that it shall not (a) sell, assign, transfer (including by operation of law), pledge, dispose of, permit to exist any material lien with respect to, or otherwise encumber any of the Shares or otherwise agree to do any of the foregoing, except to another stockholder of Novus that is a party to this Agreement and bound by the terms and obligations hereof, (b) deposit any Shares into a voting trust or enter into a voting agreement or arrangement or grant any proxy or power of attorney with respect thereto that is inconsistent with this Agreement or (c) enter into any contract, option or other arrangement or undertaking with respect to the direct or indirect acquisition or sale, assignment, transfer (including by operation of law) or other disposition of any Shares, except as permitted in clause (a) of

A-89

TABLE OF CONTENTS

this Section 3; provided, that the foregoing shall not prohibit the transfer of the Shares to (i) if Stockholder is an individual (A) to any affiliate of such Stockholder, member of such Stockholder’s immediate family, or to a trust for the direct or indirect benefit of Stockholder or any member of Stockholder’s immediate family, the sole trustees of which are such Stockholder or any member of such Stockholder’s immediate family, (B) as a bona fide gift to any charitable organization or (C) by will, other testamentary document or under the laws of intestacy upon the death of Stockholder; or (ii) if Stockholder is an entity, any equityholder, partner, member, or affiliate of Stockholder, or any investment fund or other entity controlling, controlled by, managed by or under common control with the Stockholder or affiliates of the Stockholder, but only if, in the case of clause (i) and (ii), such transferee shall execute this Agreement or a joinder agreeing to become a party to this Agreement.

4. Exclusivity. Unless this Agreement shall have been terminated in accordance with Section 9, each Stockholder, severally and not jointly, agrees not to, and shall cause its Representatives not to, directly or indirectly, solicit, initiate, continue, or engage in any discussions or negotiations with, or enter into any agreement with, or encourage or respond to any inquiries or proposals by, or participate in any negotiations with, or provide any information to, or commence due diligence with respect to, or otherwise cooperate in any way, with any person or other entity or “group” within the meaning of Section 13(d) of the Exchange Act, concerning, relating to, or which is intended or is reasonably likely to give rise to or result in, a Novus Business Combination Proposal, as such term is defined in the BCA. Each Stockholder shall, and shall direct its Representatives to, immediately cease any and all existing discussions or negotiations with any person conducted heretofore with respect to any Novus Business Combination Proposal (other than the transactions contemplated by the BCA) to the extent required by the BCA.

5. Entry into Closing Agreements. Each Stockholder is delivering, simultaneously herewith, a Stockholder Rights Agreement with Novus, the Company and the stockholders of the Company. Unless this Agreement shall have been terminated in accordance with Section 9, each Stockholder, severally and not jointly, agrees that such Stockholder shall execute and deliver to Novus a copy of each of the Sponsor Restricted Stock Agreement and the Amended and Restated Registration Rights Agreement (each in substantially the form attached to the BCA) at Closing.

6. Loans and Advances. Each Stockholder waives any rights under any contract or arrangement with Novus to convert all or any portion of any amounts loaned or advanced to Novus or its subsidiaries at any time prior to or at the Closing into warrants to purchase shares of Novus Common Stock.

7. Representations and Warranties. Each Stockholder, severally and not jointly, represents and warrants to Novus as follows:

The restrictions set forth pursuant to Section 3 above, the Sponsor Restricted Stock Agreement, and the Lock-Up Agreement are collectively referred to as the “Transfer Restrictions”). Each Stockholder acknowledges and agrees that the Restricted Sponsor Shares shall be subject to the Transfer Restrictions until such Transfer Restrictions expire in accordance with the terms of this Agreement, the Lock-Up Agreement, and/or the Sponsor Restricted Stock Agreement, as applicable, respectively.

(c) Legends. The books and records of Novus evidencing the Restricted Sponsor Shares shall be stamped or otherwise imprinted with a legend (the “Legend”) in substantially the following form:

(c) If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

(d) This Agreement, together with the BCA, the Sponsor Restricted Stock Agreement and the Lock-Up Agreement, contains the entire agreement of the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof, including the Letter Agreement (the “Insider Letter Agreement”) entered into in February 2021, between the Stockholders and Novus and delivered to Novus and the Representative, as defined therein, to the extent any of the provisions hereof are inconsistent therewith, it being acknowledged that the Insider Letter Agreement will terminate by its terms upon the Effective Date and shall continue in full force and effect, unamended hereby upon the termination of this Agreement pursuant to Section 9 (b) or (c) hereof.

No waivers of or exceptions to any term, condition, or provision of this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such

term, condition, or provision. This Agreement shall not be assigned (whether pursuant to a merger, by operation of law or otherwise), by any party without the prior express written consent of Novus and the Company.

(e) Except as set forth below, this Agreement shall be binding upon and inure solely to the benefit of each party hereto (and Novus’ permitted assigns), and nothing in this Agreement, express or implied, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. No Stockholder shall be liable for the breach by any other Stockholder of this Agreement. The covenants and obligations of each Stockholder set forth in this Agreement shall be construed as independent of any other contract between such Stockholder, on the one hand, and the Company or Novus, on the other hand. The existence of any claim or cause of action by any such Stockholder against the Company or Novus shall not constitute a defense to the enforcement of any of such covenants or obligations against such Stockholder. Nothing in this Agreement shall limit any of the rights or remedies of Novus or the Company under the BCA, or any of the rights or remedies of Novus or the Company or any of the obligations such Stockholder under any agreement between such Stockholder or the Company or any certificate or instrument executed by such Stockholder in favor of Novus or the Company; and nothing in the BCA or in any other such agreement, certificate or instrument, shall limit any of the rights or remedies of the Company or any of the obligations of such Stockholder under this Agreement.

(f) The parties hereto agree that irreparable damage would occur in the event any provision of this Agreement was not performed in accordance with the terms hereof and that the parties shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or in equity without the necessity of proving the inadequacy of money damages as a remedy and without bond or other security being required, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the parties hereto hereby further acknowledges that the existence of any other remedy contemplated by this Agreement does not diminish the availability of specific performance of the obligations hereunder or any other injunctive relief. Each party hereto hereby further agrees that in the event of any action by any other party for specific performance or injunctive relief, it will not assert that a remedy at law or other remedy would be adequate or that specific performance or injunctive relief in respect of such breach or violation should not be available on the grounds that money damages are adequate or any other grounds.

(g) This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware applicable to contracts executed in and to be performed in that State. All Actions arising out of or relating to this Agreement shall be heard and determined exclusively in the Delaware Chancery Court. The parties hereto hereby (i) submit to the exclusive jurisdiction of the Delaware Chancery Court for the purpose of any Action arising out of or relating to this Agreement brought by any party hereto, and (ii) irrevocably waive, and agree not to assert by way of motion, defense, or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement or the transactions contemplated hereunder may not be enforced in or by any of the above-named courts.

(h) This Agreement may be executed and delivered (including by facsimile or portable document format (pdf) transmission) in counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

(i) At the request of Novus or the Company, in the case of any Stockholder, at the request of Novus, in the case of the Company, or at the request of the Company, in the case of Novus, and without further consideration, each party shall execute and deliver or cause to be executed and delivered such additional documents and instruments and take such further action as may be reasonably necessary to consummate the transactions contemplated by this Agreement.

(j) This Agreement shall not be effective or binding upon any Stockholder until such time as the BCA is executed and delivered by the Company, Novus and Merger Sub.

TABLE OF CONTENTS

AMENDED AND RESTATED SPONSOR RESTRICTED STOCK AGREEMENT

This AMENDED AND RESTATED RESTRICTED STOCK AGREEMENT, dated as of [•], 2021 (“Agreement”), by and among NOVUS CAPITAL CORPORATION II, a Delaware corporation (“Novus”), the stockholders of Novus listed on Exhibit A hereto (the “Stockholders”) and Energy Vault, Inc., a Delaware corporation (the “Company”).

WHEREAS, Novus was formed for the purpose of completing a merger, stock exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities.

WHEREAS, 7,187,500 shares of common stock of Novus, par value $0.0001 per share, (“Novus Common Stock”) are held by the Stockholders (the “Founders Shares”).

WHEREAS, reference is made to the Investment Management Agreement (“Investment Management Agreement”) between Novus and Continental Stock Transfer & Trust Company, a New York corporation, Novus’ transfer agent, as Trustee (“CST”) dated February 3, 2021 pursuant to which the Trustee holds the trust account consisting of $287,500,000 together with additional property as described in the Investment Management Trust Agreement (the “Trust Account”) for the benefit of Novus and its public stockholders.

WHEREAS, Novus, NCCII Merger Corp., a Delaware corporation and wholly owned subsidiary of Novus (“Merger Sub”), and the Company have entered into a business combination agreement and plan of reorganization (the “BCA”; terms used but not defined in this Agreement shall have the meanings ascribed to them in the BCA), which provides, among other things, that, upon the terms and subject to the conditions thereof, Merger Sub will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Novus.

WHEREAS, the Stockholders are entering into this Agreement as a condition of, and as a material inducement for the Company to enter into and consummate the transactions contemplated by the BCA, including the Closing of the Merger.

WHEREAS, upon the Closing of the Merger, the Restricted Shares will be placed in escrow pursuant to an escrow agreement by and among Novus, the Stockholders and CST, as escrow agent (the “Escrow Agreement”).

WHEREAS, as a condition of, and as a material inducement for the Company to enter into and consummate the transactions contemplated by the BCA, Novus and the Stockholders have entered into a Stockholder Support Agreement, dated as of September 8, 2021 (the “Support Agreement”) and are entering into a Sponsor Lock-Up Agreement, dated on or about the date hereof (the “Lock-Up Agreement”). WHEREAS, in exchange for accepting an additional $50 million of PIPE Investment, the parties have agreed to amend the terms of this Agreement.

1. Forfeiture by of Founder Shares. Novus and each Stockholder agree that effective upon the Closing, the Stockholders shall irrevocably and automatically forfeit and surrender to Novus for cancellation, for no additional consideration and without action on the part of any other person, an aggregate of 718,750 Founder Shares (the “Forfeited Shares”). The number of shares of Common Stock each Stockholder shall forfeit as Forfeiture Shares shall be determined on a pro rata basis, relative to the number of Founder Shares owned by each Stockholder immediately prior to the Closing, such that a number of Founder Shares held by each Stockholder equal to (i) the product of the aggregate number of Forfeited Shares and (ii) a fraction equal to the aggregate number of Founder Shares held by such Stockholder immediately prior to the Closing, divided by 7,187,500 as set forth on Exhibit A hereto shall be subject to the restrictions set forth in this Agreement.

2. Share Restriction. The Company, Novus and the Stockholders hereby agree that concurrently with the Closing, the Founders Shares (other than those Founders Shares forfeited pursuant to Section 2) shall be held in escrow pursuant to the Escrow Agreement and that Novus shall instruct CST that the Restricted Shares (as defined below) shall be subject to potential forfeiture until vested in accordance with Section 4 and the further restrictions on transfer set forth in this Agreement the Sponsor Support Agreement and the Lock-Up Agreement.

A-101

TABLE OF CONTENTS

3. Restricted Shares.

3.1 Novus and each Stockholder agree that the Aggregate Number of Restricted Shares shall be subject to the restrictions set forth in this Agreement (“Restricted Shares”). The number of Restricted Shares of each Stockholder shall be determined on a pro rata basis, relative to the number of Founders Shares owned by each Stockholder immediately prior to the Closing, such that a number of Founder Shares equal to (i) the product of the Aggregate Number of Restricted Shares and (ii) a fraction equal to the aggregate number of Founder Shares held by such Stockholder immediately prior to the Closing, divided by 7,187,500 as set forth on Exhibit A hereto shall be subject to the restrictions set forth in this Agreement. The Stockholders acknowledge that the Restricted Shares will be legended to reflect the transfer restrictions applicable to the Restricted Shares under this Agreement.

3.2 The Aggregate Number of Restricted Shares shall be 4,851,562. The Founders Shares means the 7,187,500 shares of common stock of Novus held by the Stockholders.

3.3 Legends. The books and records of Novus evidencing the Restricted Shares shall be stamped or otherwise imprinted with a legend (the “Legend”) in substantially the following form:

THE SECURITIES EVIDENCED HEREIN ARE SUBJECT TO RESTRICTIONS ON TRANSFER, AND CERTAIN OTHER AGREEMENTS, SET FORTH IN THE SPONSOR RESTRICTED STOCK AGREEMENT, DATED AS OF [ ], 2021, THE LOCK-UP AGREEMENT, DATED AS OF [ ], 2021 AND THE STOCKHOLDER SUPPORT AGREEMENT DATED AS OF SEPTEMBER 8, 2021, BY AND AMONG NOVUS CAPITAL CORPORATION II AND THE OTHER PARTIES THERETO.

4. Vesting and Forfeiture of Founder Shares.

4.1 The Restricted Shares shall be subject to the transfer restrictions set forth herein until satisfaction of the following trigger events (each, a “Triggering Event”):

(a) 808,594 Founders Shares (approximately 11.125% of the Founders Shares) shall be released upon the date on which (x) the closing price of the Novus Common Stock (as adjusted for share splits, share capitalizations, reorganizations, recapitalizations and the like) exceeds $12.50 per share for any 20 trading days within a 30-trading day period occurring from the announcement of the PIPE (as defined in the Business Combination Agreement) through the thirty-six (36) month anniversary of the closing of the Merger (the “Closing Date”) or (y) Novus consummates a sale, merger, liquidation, exchange offer, transaction after the Merger (a “Subsequent Transaction”) which results in the stockholders of Novus having the right to exchange their shares of Novus Common Stock for cash, securities or other property having a value of at least $12.50 per share (for any noncash proceeds, determined based on the valuation set forth in the definitive agreements for such transaction or, in the absence of such valuation in good faith by the board of directors of Novus),

(b) 808,594 Founders Shares (approximately 11.125% the Founders Shares shall be released upon the date on which (x) the closing price of the Novus Common Stock (as adjusted for share splits, share capitalizations, reorganizations, recapitalizations and the like) equals or exceeds $15.00 per share for any 20 trading days within a 30-trading day period occurring from the announcement of the PIPE through the thirty-six (36) month anniversary of the Closing Date or (y) Novus consummates a Subsequent Transaction which results in the stockholders of Novus having the right to exchange their shares of Novus Common Stock for cash, securities or other property having a value of at least $15.00 per share (for any noncash proceeds, determined based on the valuation set forth in the definitive agreements for such transaction or, in the absence of such valuation, in good faith by the board of directors of Novus), and

(c) 3,234,375 Founders Shares (approximately 66 2/3% of the 67.5% of the Founders Shares not subject to Section 2 or Section 4.1(a) or (b) above, (or 45.0% of the Founders Shares), shall be subject to forfeiture (the “Forfeiture Percentage”) proportionately with redemptions of cash from the Trust Account held by the Trustee in excess of $25,000,000. The Forfeiture Percentage shall be calculated by (1) dividing (A) the aggregate dollar amount of cash redeemed from the Trust

A-102

TABLE OF CONTENTS

Account in excess of $25,000,000 by (B) $287,500,000 and then (2) multiplying the quotient obtained in subsection (c)(1) by 45.0%. The Forfeiture Percentage shall be multiplied by the total Founders Shares held by each Stockholder as set forth on Exhibit A attached hereto to determine the number of Founders Shares forfeited by such Stockholder. Notwithstanding the foregoing, in the event that more than 26,250,000 shares of Novus Common Stock are redeemed from the Trust Account (resulting in $262,500,000 of cash redeemed from the Trust Account assuming a redemption price of $10.00 per share), such 3,234,375 Founder Shares shall be forfeited in lieu of applying the Forfeiture Percentage.

(d) For example, if holders of shares of Novus Common Stock redeem 9,687,500 which reduces the cash in the SPAC Trust Account by $96.875 million ($25,000,000 plus 25% of $287,500,000), the Founders Shares would be treated as follows:

$71,875,000 = 25% the aggregate dollar amount of cash redeemed from the Trust Account in excess of $25,000,000 (based on $96,875,000 total redeemed from the Trust Account)

$71,875,000/$287,500,000 = 25% (45.0% of 75% of the Founders Shares impacted negatively by 25%, which is the Forfeiture Percentage).

45.0% of the Founders Shares would be reduced by the Forfeiture Percentage of 25% (i.e., 11.25% of the Founders Shares would be forfeited).

(e) The remaining 1,617,187 Founders Shares (approximately 22.5% of the Founders Shares) are not subject to the vesting restrictions or forfeiture provisions set forth in Section 2 or Section 4.1, (a)-(c).

4.2 Notwithstanding anything to the contrary, the Stockholders hereby agree that in the event that (i) the Trigger Event set forth in Section 4.1 (a) does not occur prior to the third (3rd) anniversary of the Closing Date (such period of time during which the Restricted Shares are subject to the transfer restrictions set forth herein, the “Restricted Period”), the number of Restricted Shares subject to forfeiture pursuant to Section 4.1(a) shall be forfeited to Novus and canceled and no Stockholder shall have any rights with respect thereto and (ii) the Trigger Event set forth in Section 4.1 (b) does not occur prior to the third (3rd) anniversary of the Closing Date (such period of time during which the Restricted Shares are subject to the transfer restrictions set forth herein, the “Restricted Period”), the number of Restricted Shares subject to forfeiture pursuant to Section 4.1(b) shall be forfeited to Novus and canceled and no Stockholder shall have any rights with respect thereto.

4.3 As soon as practicable, and in any event within two (2) business days after the occurrence of a Triggering Event with respect to the applicable Restricted Shares as set forth in Section 3.1, Novus shall cause any legend reflecting the limitation of transferability, the risk of forfeiture and other restrictions under this Agreement to be removed from such vested Restricted Shares. For the avoidance of doubt, to the extent then-applicable, such shares will remain subject to the restrictions set forth in the Lock-Up Agreement.

5. Rights of Stockholders in the Restricted Shares.

5.1 Voting Rights as a Stockholder. Subject to the terms of the Support Agreement described in Section 4.1 hereof and except as herein provided, the Stockholders shall retain all of their rights as stockholders of Novus as long as any shares are held in escrow pursuant to this Agreement, including, without limitation, the right to vote such shares.

5.2 Dividends and Other Distributions in Respect of the Restricted Shares. For as long as any shares are Restricted Shares, all dividends payable in cash with respect to such Restricted Shares shall be paid to the Stockholders, but all dividends payable in stock or other non-cash property (“Non-Cash Dividends”) (for the avoidance of doubt, excluding stock or other non-cash property issued pursuant to share splits, share capitalizations, reorganizations, recapitalizations and similar transactions) shall be set aside and not paid until the Restricted Shares have been vested and released to the Stockholder or, if the Restricted Shares are not vested and released in accordance with this Agreement, then all such

A-103

TABLE OF CONTENTS

distributions declared on such Restricted Shares shall be forfeited. As used herein, the term “Restricted Shares” shall be deemed to include the Non-Cash Dividends distributed thereon, if any.

5.3 Restrictions on Transfer. During the Restricted Period, each Stockholder, severally and not jointly, agrees that it shall not sell, assign, transfer (including by operation of law), pledge, dispose of, permit to exist any material lien with respect to, or otherwise encumber any of the Restricted Shares or otherwise agree to do any of the foregoing, except to another stockholder of Novus that is a party to this Agreement and bound by the terms and obligations hereof, deposit any Restricted Shares into a voting trust or enter into a voting agreement or arrangement or grant any proxy or power of attorney with respect thereto that is inconsistent with this Agreement or enter into any contract, option or other arrangement or undertaking with respect to the direct or indirect acquisition or sale, assignment, transfer (including by operation of law) or other disposition of any Restricted Shares, except to such other stockholder of Novus that is a party to this Agreement and bound by the terms and obligations hereof (including by executing a joinder agreeing to be bound by this Agreement); provided, that the foregoing shall not prohibit the transfer of the Restricted Shares to (i) if Stockholder is an individual (A) to any affiliate of such Stockholder, member of such Stockholder’s immediate family, or to a trust for the direct or indirect benefit of Stockholder or any member of Stockholder’s immediate family, the sole trustees of which are such Stockholder or any member of such Stockholder’s immediate family, (B) as a bona fide gift to any charitable organization or (C) by will, other testamentary document or under the laws of intestacy upon the death of Stockholder; or (ii) if Stockholder is an entity, any equityholder, partner, member, or affiliate of Stockholder, or any investment fund or other entity controlling, controlled by, managed by or under common control with the Stockholder or affiliates of the Stockholder, but only if, in the case of clause (i) and (ii), such transferee shall execute this Agreement or a joinder agreeing to become a party to this Agreement.

6. Miscellaneous.

TABLE OF CONTENTS

Energy Vault Holdings, Inc.

Second Amended and Restated Certificate of Incorporation

Novus Capital Corporation II, a corporation organized and existing under the laws of the State of Delaware, hereby certifies as follows:

1. The name of the corporation is Novus Capital Corporation II, which was the name under which the corporation was originally incorporated. The date of the filing of its original certificate of incorporation with the Secretary of State of the State of Delaware was September 29, 2020.

2. This Second Amended and Restated Certificate of Incorporation, which restates, integrates and further amends the certificate of incorporation of the corporation, has been duly adopted by the corporation in accordance with Sections 242 and 245 of the General Corporation Law of the State of Delaware and has been adopted by the requisite vote of the stockholders of the corporation in accordance with the General Corporation Law of the State of Delaware.

3. The certificate of incorporation of the corporation is hereby amended and restated in its entirety to read as follows:

FIRST: The name of the corporation is Energy Vault Holdings, Inc. (hereinafter called the “Corporation”).

SECOND: The address of the registered office of the Corporation in the State of Delaware is 160 Greentree Drive, Suite 101, in the City of Dover, County of Kent, Delaware 19904. The name of the registered agent of the Corporation in the State of Delaware at such address is National Registered Agents, Inc.

THIRD: The purpose of the Corporation is to engage in any lawful act or activity for which corporations may be organized and incorporated under the General Corporation Law of the State of Delaware or any applicable successor act thereto, as the same may be amended from time to time (the “DGCL”).

FOURTH: The total number of shares of all classes of capital stock that the Corporation is authorized to issue is 505,000,000 shares, consisting of (i) 500,000,000 shares of common stock, par value $0.0001 per share (the “Common Stock”), and (ii) 5,000,000 shares of preferred stock, par value $0.0001 per share (“Preferred Stock”). Subject to the rights of the holders of any series of Preferred Stock, the number of authorized shares of any of the Common Stock or Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority in voting power of the capital stock of the Corporation entitled to vote thereon irrespective of the provisions of Section 242(b)(2) of the DGCL, and no vote of the holders of any of the Common Stock or Preferred Stock voting separately as a class shall be required therefor.

A. Common Stock. The powers, preferences and relative participating, optional or other special rights, and the qualifications, limitations and restrictions of the Common Stock are as follows:

1. Ranking. The voting, dividend and liquidation rights of the holders of the Common Stock are subject to and qualified by the rights of the holders of the Preferred Stock of any series as may be designated by the Board of Directors of the Corporation (the “Board”) upon any issuance of the Preferred Stock of any series.

2. Voting. Except as otherwise provided by law or by the resolution or resolutions providing for the issue of any series of Preferred Stock, the holders of outstanding shares of Common Stock shall have the exclusive right to vote for the election and removal of directors and for all other purposes. Each outstanding share of Common Stock shall entitle the holder thereof to one vote on each matter properly submitted to the stockholders of the Corporation for their vote. Notwithstanding any other provision of this Second Amended and Restated Certificate of Incorporation (as amended from time to time, including the terms of any Preferred Stock Designation (as defined below), this “Certificate of Incorporation”) to the contrary, the holders of Common Stock shall not be entitled to vote on any

A-115

TABLE OF CONTENTS

amendment to this Certificate of Incorporation (including any Preferred Stock Designation) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together as a class with the holders of one or more other such series, to vote thereon pursuant to this Certificate of Incorporation (including any Preferred Stock Designation) or the DGCL.

3. Dividends. Subject to the rights of the holders of Preferred Stock, holders of shares of Common Stock shall be entitled to receive such dividends and distributions and other distributions in cash, stock or property of the Corporation when, as and if declared thereon by the Board from time to time out of assets or funds of the Corporation legally available therefor.

4. Liquidation. Subject to the rights of the holders of Preferred Stock, shares of Common Stock shall be entitled to receive the assets and funds of the Corporation available for distribution in the event of any liquidation, dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary. A liquidation, dissolution or winding up of the affairs of the Corporation, as such terms are used in this Section A(4), shall not be deemed to be occasioned by or to include any consolidation or merger of the Corporation with or into any other person or a sale, lease, exchange or conveyance of all or a part of its assets.

B. Preferred Stock

Shares of Preferred Stock may be issued from time to time in one or more series. The Board is hereby authorized to provide by resolution or resolutions from time to time for the issuance, out of the unissued shares of Preferred Stock, of one or more series of Preferred Stock, without stockholder approval, by filing a certificate pursuant to the applicable law of the State of Delaware (the “Preferred Stock Designation”), setting forth such resolution and, with respect to each such series, establishing the number of shares to be included in such series, and fixing the voting powers, full or limited, or no voting power of the shares of such series, and the designation, preferences and relative, participating, optional or other special rights, if any, of the shares of each such series and any qualifications, limitations or restrictions thereof. The powers, designation, preferences and relative, participating, optional and other special rights of each series of Preferred Stock, and the qualifications, limitations and restrictions thereof, if any, may differ from those of any and all other series at any time outstanding. The authority of the Board with respect to each series of Preferred Stock shall include, but not be limited to, the determination of the following:

(a) the designation of the series, which may be by distinguishing number, letter or title;

(b) the number of shares of the series, which number the Board may thereafter (except where otherwise provided in the Preferred Stock Designation) increase or decrease (but not below the number of shares thereof then outstanding);

(c) the amounts or rates at which dividends will be payable on, and the preferences, if any, of shares of the series in respect of dividends, and whether such dividends, if any, shall be cumulative or noncumulative;

(d) the dates on which dividends, if any, shall be payable;

(e) the redemption rights and price or prices, if any, for shares of the series;

(f) the terms and amount of any sinking fund, if any, provided for the purchase or redemption of shares of the series;

(g) the amounts payable on, and the preferences, if any, of shares of the series in the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation;

(h) whether the shares of the series shall be convertible into or exchangeable for, shares of any other class or series, or any other security, of the Corporation or any other corporation, and, if so, the specification of such other class or series or such other security, the conversion or exchange price or prices or rate or rates, any adjustments thereof, the date or dates at which such shares shall be convertible or exchangeable and all other terms and conditions upon which such conversion or exchange may be made;

A-116

TABLE OF CONTENTS

(i) restrictions on the issuance of shares of the same series or any other class or series;

(j) the voting rights, if any, of the holders of shares of the series generally or upon specified events; and

Without limiting the generality of the foregoing, the resolutions providing for issuance of any series of Preferred Stock may provide that such series shall be superior or rank equally or be junior to any other series of Preferred Stock to the extent permitted by law.

FIFTH: This Article FIFTH is inserted for the management of the business and for the conduct of the affairs of the Corporation.

A. General Powers. The business and affairs of the Corporation shall be managed by or under the direction of the Board, except as otherwise provided by law.

B. Number of Directors; Election of Directors. Subject to the rights of holders of any series of Preferred Stock to elect directors, the number of directors of the Corporation shall be fixed from time to time by resolution of the majority of the Whole Board. For purposes of this Certificate of Incorporation, the term “Whole Board” will mean the total number of authorized directors, whether or not there exist any vacancies in previously authorized directorships. No decrease in the number of directors constituting the Board shall shorten the term of any incumbent director.

C. Classes of Directors. Subject to the rights of holders of any series of Preferred Stock to elect directors, the Board shall be and is divided into three classes, designated Class I, Class II and Class III. Each class shall consist, as nearly as may be possible, of one third of the total number of directors constituting the entire Board. The Board is authorized to assign members of the Board already in office to Class I, Class II or Class III at the time such classification becomes effective.

D. Terms of Office. Subject to the rights of holders of any series of Preferred Stock to elect directors, each director shall serve for a term ending on the date of the third annual meeting of stockholders following the annual meeting of stockholders at which such director was elected; provided that each director initially assigned to Class I shall serve for a term expiring at the Corporation’s first annual meeting of stockholders held after the effectiveness of this Certificate of Incorporation; each director initially assigned to Class II shall serve for a term expiring at the Corporation’s second annual meeting of stockholders held after the effectiveness of this Certificate of Incorporation; and each director initially assigned to Class III shall serve for a term expiring at the Corporation’s third annual meeting of stockholders held after the effectiveness of this Certificate of Incorporation; provided further, that the term of each director shall continue until the election and qualification of his or her successor and be subject to his or her earlier death, disqualification, resignation or removal.

E. Vacancies. Subject to the rights of holders of any series of Preferred Stock, any newly created directorship that results from an increase in the number of directors or any vacancy on the Board that results from the death, disability, resignation, disqualification or removal of any director or from any other cause shall be filled solely by the affirmative vote of a majority of the total number of directors then in office, even if less than a quorum, or by a sole remaining director and shall not be filled by the stockholders. Any director elected to fill a vacancy not resulting from an increase in the number of directors shall hold office for the remaining term of his or her predecessor.

F. Removal. Any director or the entire Board may be removed from office at any time, but only for cause and only by the affirmative vote of the holders of at least 66 2/3% in voting power of the stock of the Corporation entitled to vote thereon.

G. Committees. Pursuant to the Amended and Restated Bylaws of the Corporation (the “Bylaws”), the Board may establish one or more committees to which may be delegated any or all of the powers and duties of the Board to the full extent permitted by law.

A-117

TABLE OF CONTENTS

H. Stockholder Nominations and Introduction of Business. Advance notice of stockholder nominations for election of directors and other business to be brought by stockholders before a meeting of stockholders shall be given in the manner provided by the Bylaws.

SIXTH: Unless and except to the extent that the Bylaws shall so require, the election of directors of the Corporation need not be by written ballot.

SEVENTH: To the fullest extent permitted by the DGCL as it now exists and as it may hereafter be amended, no director of the Corporation shall be personally liable to the Corporation or any of its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or hereafter may be amended. No repeal or modification of this Article SEVENTH shall apply to or have any adverse effect on any right or protection of, or any limitation of the liability of, a director of the Corporation existing at the time of such repeal or modification with respect to acts or omissions occurring prior to such repeal or modification.

EIGHTH: The Corporation may indemnify, and advance expenses to, to the fullest extent permitted by law, any person who was or is a party to or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that the person is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise.

NINTH: Subject to the terms of any series of Preferred Stock, any action required or permitted to be taken by the stockholders of the Corporation must be effected at an annual or special meeting of the stockholders called in accordance with the Bylaws and may not be effected by written consent in lieu of a meeting.

TENTH: Except as otherwise required by law and subject to the terms of any series of preferred Stock, special meetings of stockholders for any purpose or purposes may be called at any time by the majority of the Whole Board, the Chairman of the Board or the Chief Executive Officer of the Corporation, and may not be called by any other person or persons. Business transacted at any special meeting of stockholders shall be limited to matters relating to the purpose or purposes stated in the notice of such meeting.

ELEVENTH: If any provision or provisions of this Certificate of Incorporation shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any reason whatsoever: (i) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Certificate of Incorporation (including, without limitation, each portion of any paragraph of this Certificate of Incorporation containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and (ii) to the fullest extent possible, the provisions of this Certificate of Incorporation (including, without limitation, each such portion of any paragraph of this Certificate of Incorporation containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to permit the Corporation to protect its directors, officers, employees and agents from personal liability in respect of their good faith service or for the benefit of the Corporation to the fullest extent permitted by law.

A-118

TABLE OF CONTENTS

of this Certificate of Incorporation; provided, however, that the affirmative vote of the holders of at least 66 2/3% in voting power of the stock of the Corporation entitled to vote thereon shall be required to amend, alter, change or repeal, or adopt any provision inconsistent with, any of Article FIFTH, Article SEVENTH, Article EIGHTH, Article NINTH, Article TENTH, Article TWELFTH, Article THIRTEENTH, and this sentence of this Certificate of Incorporation, or in each case, the definition of any capitalized terms used therein or any successor provision (including, without limitation, any such article or section as renumbered as a result of any amendment, alteration, change, repeal or adoption of any other provision of this Certificate of Incorporation). Any amendment, repeal or modification of any of Article SEVENTH, Article EIGHTH, and this sentence shall not adversely affect any right or protection of any person existing thereunder with respect to any act or omission occurring prior to such repeal or modification.

TWELFTH: In furtherance and not in limitation of the powers conferred upon it by law, the Board is expressly authorized and empowered to adopt, amend and repeal the Bylaws by the affirmative vote of a majority of the Whole Board. Notwithstanding any other provision of this Certificate of Incorporation or any provision of law that might otherwise permit a lesser vote or no vote, but in addition to any affirmative vote of the holders of any series of Preferred Stock required by law, by this Certificate of Incorporation or by any Preferred Stock Designation, the Bylaws may also be amended, altered or repealed and new Bylaws may be adopted by the affirmative vote of the holders of at least 66 2/3% in voting power of the stock of the Corporation entitled to vote thereon.

THIRTEENTH:

A. Forum Selection. Unless the Corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) shall, to the fullest extent permitted by law, be the sole and exclusive forum for (1) any derivative action or proceeding brought on behalf of the Corporation, (2) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Corporation to the Corporation or the Corporation’s stockholders, (3) any action arising pursuant to any provision of the DGCL or this Certificate of Incorporation or the Bylaws (as either may be amended from time to time), or (4) any action asserting a claim governed by the internal affairs doctrine. Unless the Corporation consents in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended. Any person or entity purchasing or otherwise acquiring or holding any interest in shares of capital stock of the Corporation shall be deemed to have notice of and consented to the provisions of this Article THIRTEENTH.

B. Personal Jurisdiction. If any action the subject matter of which is within the scope of Section A immediately above is filed in a court other than a court located within the State of Delaware (a “Foreign Action”) in the name of any stockholder, such stockholder shall be deemed to have consented to (i) the personal jurisdiction of the state and federal courts located within the State of Delaware in connection with any action brought in any such court to enforce Section A immediately above (an “FSC Enforcement Action”) and (ii) having service of process made upon such stockholder in any such FSC Enforcement Action by service upon such stockholder’s counsel in the Foreign Action as agent for such stockholder.

Article I
Stockholders

1.1 Place of Meetings. All meetings of stockholders shall be held at such place, if any, as may be designated from time to time by the Board of Directors (the “Board”) of Energy Vault Holdings, Inc. (the “Corporation”), the Chairman of the Board, the Chief Executive Officer or the President or, if not so designated, at the principal executive office of the Corporation. The Board may, in its sole discretion, determine that a meeting shall not be held at any place, but may instead be held solely by means of remote communication in accordance with Section 211(a) of the General Corporation Law of the State of Delaware or any applicable successor act thereto, as the same may be amended from time to time (the “DGCL”).

1.2 Annual Meeting. The annual meeting of stockholders for the election of directors to succeed those whose terms expire and for the transaction of such other business as may properly be brought before the meeting shall be held on a date and at a time designated by the Board, the Chairman of the Board, the Chief Executive Officer or the President (which date shall not be a legal holiday in the place, if any, where the meeting is to be held). The Board acting pursuant to a resolution adopted by the majority of the Whole Board may postpone, reschedule or cancel any previously scheduled annual meeting of stockholders, before or after the notice for such meeting has been sent to the stockholders. For purposes of these Amended and Restated Bylaws (the “Bylaws”), the term “Whole Board” will mean the total number of authorized directors whether or not there exist any vacancies in previously authorized directorships.

1.3 Special Meetings. Special meetings of stockholders for any purpose or purposes may be called at any time by a resolution adopted by the majority of the Whole Board, the Chairman of the Board or the Chief Executive Officer, and may not be called by any other person or persons. The Board acting pursuant to a resolution adopted by the majority of the Whole Board may postpone, reschedule or cancel any previously scheduled special meeting of stockholders, before or after the notice for such meeting has been sent to the stockholders. Business transacted at any special meeting of stockholders shall be limited to matters relating to the purpose or purposes stated in the notice of meeting.

1.4 Notice of Meetings. Except as otherwise provided by law, notice of each meeting of stockholders, whether annual or special, shall be given not less than ten (10) nor more than sixty (60) days before the date of the meeting to each stockholder entitled to vote at such meeting as of the record date for determining the stockholders entitled to notice of the meeting. Without limiting the manner by which notice otherwise may be given to stockholders, any notice shall be effective if given by a form of electronic transmission consented to (in a manner consistent with the DGCL) by the stockholder to whom the notice is given. The notices of all meetings shall state the place, if any, date and time of the meeting, the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting, and the record date for determining the stockholders entitled to vote at the meeting (if such date is different from the record date for stockholders entitled to notice of the meeting). The notice of a special meeting shall state, in addition, the purpose or purposes for which the meeting is called. If notice is given by mail, such notice shall be deemed given when deposited in the United States mail, postage prepaid, directed to the stockholder at such stockholder’s address as it appears on the records of the Corporation. If notice is given by electronic transmission, such notice shall be deemed given at the time specified in Section 232 of the DGCL.

1.5 Voting List. The Secretary shall prepare, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting (provided, however, if the record date for determining the stockholders entitled to vote is less than ten (10) days before the date of the meeting, the list shall reflect the stockholders entitled to vote as of the tenth day before the meeting date), arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, for a period of at least ten (10) days prior to the meeting: (a) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (b) during ordinary business hours, at the principal place of business of the Corporation. If the meeting is to be held at a place, then the list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a

A-125

TABLE OF CONTENTS

reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting. Except as otherwise provided by law, the list shall presumptively determine the identity of the stockholders entitled to vote at the meeting and the number of shares held by each of them.

1.6 Quorum. Except as otherwise provided by law, the Certificate of Incorporation or these Bylaws, the holders of a majority in voting power of the shares of the capital stock of the Corporation issued and outstanding and entitled to vote at the meeting, present in person, present by means of remote communication in a manner, if any, authorized by the Board in its sole discretion, or represented by proxy, shall constitute a quorum for the transaction of business; provided, however, that where a separate vote by a class or classes or series of capital stock is required by law or the Certificate of Incorporation, the holders of a majority in voting power of the shares of such class or classes or series of the capital stock of the Corporation issued and outstanding and entitled to vote on such matter, present in person, present by means of remote communication in a manner, if any, authorized by the Board in its sole discretion, or represented by proxy, shall constitute a quorum entitled to take action with respect to the vote on such matter. A quorum, once established at a meeting, shall not be broken by the withdrawal of enough votes to leave less than a quorum.

If, however, such quorum is not present or represented at any meeting of the stockholders, then either (i) the chairperson of the meeting, or (ii) the stockholders entitled to vote at the meeting, present in person or represented by proxy, shall have power to adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum is present or represented.

1.7 Adjournments. Any meeting of stockholders, annual or special, may be adjourned from time to time to any other time and to any other place at which a meeting of stockholders may be held under these Bylaws by the chairman of the meeting or by the stockholders present or represented at the meeting and entitled to vote thereon, although less than a quorum. If the adjournment is for more than thirty (30) days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. If after the adjournment a new record date for determination of stockholders entitled to vote is fixed for the adjourned meeting, the Board shall fix as the record date for determining stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote at the adjourned meeting, and shall give notice of the adjourned meeting to each stockholder of record as of the record date so fixed for notice of such adjourned meeting. At the adjourned meeting, the Corporation may transact any business which might have been transacted at the original meeting.

1.8 Voting and Proxies. Each stockholder shall have such number of votes, if any, for each share of stock entitled to vote and held of record by such stockholder as may be fixed in the Certificate of Incorporation and a proportionate vote for each fractional share so held, unless otherwise provided by law or the Certificate of Incorporation. Each stockholder of record entitled to vote at a meeting of stockholders may vote in person (including by means of remote communications, if any, by which stockholders may be deemed to be present in person and vote at such meeting) or may authorize another person or persons to vote for such stockholder by a proxy executed or transmitted in a manner permitted by applicable law. No such proxy shall be voted upon after three years from the date of its execution, unless the proxy expressly provides for a longer period.

1.9 Action at Meeting When a quorum is present at any meeting, any matter other than the election of directors to be voted upon by the stockholders at such meeting shall be decided by the vote of the holders of a majority of the votes cast (or if there are two or more classes or series of stock entitled to vote as separate classes, then in the case of each such class or series, the affirmative vote of a majority of the votes cast by shares of such class or series), except when a different vote is required by applicable law, regulation applicable to the Corporation or its securities, the rules or regulations of any stock exchange applicable to the Corporation, the Certificate of Incorporation or these Bylaws. For the avoidance of doubt, neither abstentions nor broker non-votes will be counted as votes cast for or against such matter. Other than directors who may be elected by the holders of shares of any series of Preferred Stock or pursuant to any resolution or resolutions providing for the issuance of such stock adopted by the Board, each director shall be elected by a plurality of the votes cast in respect of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. Voting at meetings of stockholders need not be by written ballot.

Such information provided and statements made as required by clauses (A) and (B) above or otherwise by this Section 1.10 are hereinafter referred to as a “Nominee Solicitation Statement.” Not later than ten (10) days after the record date for determining stockholders entitled to notice of the meeting, the information required by Items (A)(1)-(5) and (B)(1)-(5) of the prior sentence shall be supplemented by the stockholder giving the notice to provide updated information as of such record date. In addition, to be effective, the stockholder’s notice must be accompanied by the written consent of the proposed nominee to serve as a director if elected and a written statement executed by the proposed nominee acknowledging that as a director of the Corporation, the nominee will owe a fiduciary duty under Delaware law with respect to the Corporation and its stockholders. The Corporation may require any proposed nominee to furnish such other information as the Corporation may reasonably require to determine the eligibility of such proposed nominee to serve as a director of the Corporation or whether such nominee would be independent under applicable Securities and Exchange Commission and stock exchange rules and the Corporation’s publicly disclosed corporate governance guidelines. A stockholder shall not have complied with this Section 1.10(b) if the stockholder (or beneficial owner, if any, on whose behalf the nomination is made) solicits or does not solicit, as the case may be, proxies or votes in support of such stockholder’s nominee in contravention of the representations with respect thereto required by this Section 1.10. For purposes of these Bylaws, a “Stockholder Associated Person” of any stockholder shall mean (i) any person controlling, directly or indirectly, or acting in concert with, such stockholder, (ii) any beneficial owner of shares of stock of the corporation owned of record or beneficially by such stockholder and on whose behalf the proposal or nomination, as the case may be, is being made, or (iii) any person controlling, controlled by or under common control with such person referred to in the preceding clauses (i) and (ii).

(c) Without exception, no person shall be eligible for election or re-election as a director of the Corporation at a meeting of stockholders unless nominated in accordance with the provisions set forth

A-128

TABLE OF CONTENTS

in this Section 1.10. In addition, a nominee shall not be eligible for election or re-election if a stockholder or Stockholder Associated Person, as applicable, takes action contrary to the representations made in the Nominee Solicitation Statement applicable to such nominee or if the Nominee Solicitation Statement applicable to such nominee contains an untrue statement of a material fact or omits to state a material fact necessary to make the statements therein not misleading. The chairman of any meeting shall have the power and duty to determine whether a nomination was made in accordance with the provisions of this Section 1.10 (including the previous sentence of this Section 1.10(c)), and if the chairman should determine that a nomination was not made in accordance with the provisions of this Section 1.10, the chairman shall so declare to the meeting and such nomination shall not be brought before the meeting.

(d) Except as otherwise required by law, nothing in this Section 1.10 shall obligate the Corporation or the Board to include in any proxy statement or other stockholder communication distributed on behalf of the Corporation or the Board information with respect to any nominee for director submitted by a stockholder.

(e) Notwithstanding the foregoing provisions of this Section 1.10, unless otherwise required by law, if the stockholder (or a qualified representative of the stockholder) does not appear at the meeting to present a nomination, such nomination shall not be brought before the meeting, notwithstanding that proxies in respect of such nominee may have been received by the Corporation. For purposes of this Section 1.10, to be considered a “qualified representative of the stockholder”, a person must be authorized by a written instrument executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such written instrument or electronic transmission, or a reliable reproduction of the written instrument or electronic transmission, at the meeting of stockholders.

(g) Notwithstanding the foregoing provisions of this Section 1.10, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations promulgated thereunder with respect to the matters set forth in this Section 1.10; provided, however, that any references in these Bylaws to the Exchange Act or the rules and regulations promulgated thereunder are not intended to and shall not limit any requirements applicable to nominations to be considered pursuant to this Section 1.10 (including paragraph (a)(ii) hereof), and compliance with paragraph (a)(ii) of this Section 1.10 shall be the exclusive means for a stockholder to make nominations. Nothing in this Section 1.10 shall be deemed to affect any rights of the holders of any series of Preferred Stock to elect directors pursuant to any applicable provisions of the Certificate of Incorporation.

1.11 Notice of Business at Annual Meetings.

(a) At any annual meeting of the stockholders, only such business shall be conducted as shall have been properly brought before the meeting. To be properly brought before an annual meeting, business must be (1) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board, (2) otherwise properly brought before the meeting by or at the direction of the Board (or any committee thereof), or (3) properly brought before the annual meeting by a stockholder.

In no event shall the adjournment or postponement of an annual meeting (or the public disclosure thereof) commence a new time period (or extend any time period) for the giving of a stockholder’s notice.

The stockholder’s notice to the Secretary shall set forth: (A) as to each matter the stockholder proposes to bring before the annual meeting (1) a brief description of the business desired to be brought before the annual meeting, (2) the text of the proposal (including the exact text of any resolutions proposed for consideration and, in the event that such business includes a proposal to amend the Bylaws, the exact text of the proposed amendment), and (3) the reasons for conducting such business at the annual meeting, and (B) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the proposal is being made (1) the name and address of such stockholder, as they appear on the Corporation’s books, of such beneficial owner and of any Stockholder Associated Person, (2) the class and series and number of shares of stock of the Corporation that are, directly or indirectly, owned, beneficially or of record, by such stockholder, such beneficial owner and any Stockholder Associated Person, (3) a description of any material interest of such stockholder, such beneficial owner or any Stockholder Associated Person and the respective affiliates and associates of, or others acting in concert with, such stockholder, such beneficial owner or any Stockholder Associated Person in such business, (4) a description of any agreement, arrangement or understanding between or among such stockholder, such beneficial owner and/or any Stockholder Associated Person and any other person or persons (including their names) in connection with the proposal of such business or who may participate in the solicitation of proxies in favor of such proposal, (5) a description of any agreement, arrangement or understanding (including any derivative or short positions, swaps, profit interests, options, warrants, convertible securities, stock appreciation or similar rights, hedging transactions, and borrowed or loaned shares) that has been entered into by, or on behalf of, such stockholder, such beneficial owner or any Stockholder Associated Person, the effect or intent of which is to mitigate loss to, manage risk or benefit of share price changes for, or increase or decrease the voting power of, such stockholder, such beneficial owner or any Stockholder Associated Person with respect to shares of stock of the Corporation, (6) any other information relating to such stockholder, such beneficial owner and any Stockholder Associated Person that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for the business proposed pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder, (7) a representation that such stockholder intends to appear in person or by proxy at the annual meeting to bring such business before the meeting and (8) a representation whether such stockholder, such beneficial owner and/or any Stockholder Associated Person intends or is part of a group which intends (x) to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the Corporation’s outstanding capital stock required to approve or adopt the proposal and/or (y) otherwise to solicit proxies or votes from stockholders in support of such proposal. Such information provided and statements made as required by clauses (A) and (B) above or otherwise by this Section 1.11 are hereinafter referred to as a “Business Solicitation Statement.” Not later than ten (10) days after the record date for determining stockholders entitled to notice of the meeting, the information required by Items (A)(3) and (B)(1)-(6) of the prior sentence shall be supplemented by the stockholder giving the notice to provide updated information as of such record date. Notwithstanding anything in these Bylaws to the contrary, no business shall be conducted at any annual meeting of stockholders except in accordance with the procedures in this Section 1.11. A stockholder shall not have complied with this Section 1.11(b) if the stockholder (or beneficial owner, if any, on whose behalf the proposal is made) solicits or does not solicit, as the case may be, proxies or votes in support of such stockholder’s proposal in contravention of the representations with respect thereto required by this Section 1.11.

(c) Without exception, no business shall be conducted at any annual meeting except in accordance with the provisions set forth in this Section 1.11. In addition, business proposed to be brought by a

The chairman of any annual meeting shall have the power and duty to determine whether business was properly brought before the annual meeting in accordance with the provisions of this Section 1.11 (including the previous sentence of this Section 1.11(c)), and if the chairman should determine that business was not properly brought before the annual meeting in accordance with the provisions of this Section 1.11, the chairman shall so declare to the meeting and such business shall not be brought before the annual meeting.

(e) Notwithstanding the foregoing provisions of this Section 1.11, unless otherwise required by law, if the stockholder (or a qualified representative of the stockholder) does not appear at the annual meeting to present business, such business shall not be considered, notwithstanding that proxies in respect of such business may have been received by the Corporation.

(f) For purposes of this Section 1.11, the terms “qualified representative of the stockholder” and “public disclosure” shall have the same meaning as in Section 1.10.

(g) Notwithstanding the foregoing provisions of this Section 1.11, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations promulgated thereunder with respect to the matters set forth in this Section 1.11; provided, however, that any references in these Bylaws to the Exchange Act or the rules and regulations promulgated thereunder are not intended to and shall not limit any requirements applicable to proposals as to any business to be considered pursuant to this Section 1.11 (including paragraph (a)(3) hereof), and compliance with paragraph (a)(3) of this Section 1.11 shall be the exclusive means for a stockholder to submit business. Nothing in this Section 1.11 shall be deemed to affect any rights of stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to applicable rules and regulations promulgated under the Exchange Act.

1.12 Conduct of Meetings.

(a) Meetings of stockholders shall be presided over by the Chairman of the Board, if any, or in the Chairman’s absence by the Vice Chairman of the Board, if any, or in the Vice Chairman’s absence by the Chief Executive Officer, or in the Chief Executive Officer’s absence, by the President, or in the President’s absence by a Vice President, or in the absence of all of the foregoing persons by a chairman designated by the Board. The Secretary shall act as secretary of the meeting, but in the Secretary’s absence the chairman of the meeting may appoint any person to act as secretary of the meeting.

(b) The Board may adopt by resolution such rules, regulations and procedures for the conduct of any meeting of stockholders of the Corporation as it shall deem appropriate including, without limitation, such guidelines and procedures as it may deem appropriate regarding the participation by means of remote communication of stockholders and proxyholders not physically present at a meeting. Except to the extent inconsistent with such rules, regulations and procedures as adopted by the Board, the chairman of any meeting of stockholders shall have the right and authority to convene and (for any or no reason) to recess and/or adjourn the meeting, to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such chairman, are appropriate for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board or prescribed by the chairman of the meeting, may include, without limitation, the following: (i) the establishment of an agenda or order of business for the meeting; (ii) rules and procedures for maintaining order at the meeting and the safety of those present; (iii) limitations on attendance at or participation in the meeting to stockholders of record of the Corporation, their duly authorized and constituted proxies or such other persons as shall be determined; (iv) restrictions on entry to the meeting after

(c) The chairman of the meeting shall announce at the meeting when the polls for each matter to be voted upon at the meeting will be opened and closed. After the polls close, no ballots, proxies or votes or any revocations or changes thereto may be accepted.

(d) In advance of any meeting of stockholders, the Board, the Chairman of the Board, the Chief Executive Officer or the President shall appoint one or more inspectors of election to act at the meeting and make a written report thereof. One or more other persons may be designated as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is present, ready and willing to act at a meeting of stockholders, the chairman of the meeting shall appoint one or more inspectors to act at the meeting. Unless otherwise required by law, inspectors may be officers, employees or agents of the Corporation. Each inspector, before entering upon the discharge of such inspector’s duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of such inspector’s ability. The inspector shall have the duties prescribed by law and, when the vote is completed, shall make a certificate of the result of the vote taken and of such other facts as may be required by law. Every vote taken by ballots shall be counted by a duly appointed inspector or duly appointed inspectors.

2.1 General Powers. The business and affairs of the Corporation shall be managed by or under the direction of a Board, who may exercise all of the powers of the Corporation except as otherwise provided by law or the Certificate of Incorporation.

2.2 Number, Election and Qualification. Subject to the rights of holders of any series of Preferred Stock to elect directors, the number of directors of the Corporation shall be fixed from time to time by resolution of the majority of the Whole Board. Election of directors need not be by written ballot. Directors need not be stockholders of the Corporation.

2.3 Chairman of the Board; Vice Chairman of the Board. The Board may appoint from its members a Chairman of the Board and a Vice Chairman of the Board, neither of whom need be an employee or officer of the Corporation. If the Board appoints a Chairman of the Board, such Chairman shall perform such duties and possess such powers as are assigned by the Board and, if the Chairman of the Board is also designated as the Corporation’s Chief Executive Officer, shall have the powers and duties of the Chief Executive Officer prescribed in Section 3.7 of these Bylaws. If the Board appoints a Vice Chairman of the Board, such Vice Chairman shall perform such duties and possess such powers as are assigned by the Board. Unless otherwise provided by the Board, the Chairman of the Board or, in the Chairman’s absence, the Vice Chairman of the Board, if any, shall preside at all meetings of the Board.

2.4 Classes of Directors. Subject to the rights of holders of any series of Preferred Stock to elect directors, the Board shall be and is divided into three classes, designated: Class I, Class II and Class III. Each class shall consist, as nearly as may be possible, of one-third of the total number of directors constituting the entire Board. The Board is authorized to assign members of the Board already in office to Class I, Class II or Class III at the time such classification becomes effective. If the number of such directors is changed, any increase or decrease shall be apportioned among the classes so as to maintain the number of directors in each class as nearly equal as possible, and any such additional director of any class elected to fill a newly created directorship resulting from an increase in such class shall hold office for a term that shall coincide with the remaining term of that class, but in no case shall a decrease in the number of directors remove or shorten the term of any incumbent director.

2.5 Terms of Office. Subject to the rights of holders of any series of Preferred Stock to elect directors, and except as set forth in the Certificate of Incorporation, each director shall serve for a term ending on the date of the third annual meeting of stockholders following the annual meeting of stockholders

at which such director was elected; provided that the term of each director shall continue until the election and qualification of his or her successor and be subject to his or her earlier death, disqualification, resignation or removal.

2.6 Quorum. A majority of the Whole Board shall constitute a quorum of the Board. If at any meeting of the Board there shall be less than a quorum, a majority of the directors present may adjourn the meeting from time to time without further notice other than announcement at the meeting, until a quorum shall be present. A meeting at which a quorum is initially present may continue to transact business notwithstanding the withdrawal of directors, if any action taken is approved by at least a majority of the required quorum for that meeting.

2.7 Action at Meeting. Every act or decision done or made by a majority of the directors present at a meeting duly held at which a quorum is present shall be regarded as the act of the Board, unless a greater number is required by law or by the Certificate of Incorporation or these Bylaws.

2.8 Removal. Subject to the rights of holders of any series of Preferred Stock, directors of the Corporation may be removed only as expressly provided in the Certificate of Incorporation.

2.9 Vacancies. Subject to the rights of holders of any series of Preferred Stock, any newly created directorship that results from an increase in the number of directors or any vacancy on the Board that results from the death, disability, resignation, disqualification or removal of any director or from any other cause shall be filled solely by the affirmative vote of a majority of the total number of directors then in office, even if less than a quorum, or by a sole remaining director and shall not be filled by the stockholders. Any director elected to fill a vacancy not resulting from an increase in the number of directors shall hold office for the remaining term of his or her predecessor.

2.10 Resignation. Any director may resign only by delivering a resignation in writing or by electronic transmission to the Chairman of the Board or the Chief Executive Officer. Such resignation shall be effective upon delivery unless it is specified to be effective at some later time or upon the happening of some later event.

2.11 Regular Meetings. Regular meetings of the Board may be held without notice at such time and place as shall be determined from time to time by the Board; provided that any director who is absent when such a determination is made shall be given notice of the determination. A regular meeting of the Board may be held without notice immediately after and at the same place as the annual meeting of stockholders.

2.12 Special Meetings. Special meetings of the Board may be held at any time and place designated in a call by the Chairman of the Board, the Chief Executive Officer, the President, two or more directors, or by one director in the event that there is only a single director in office.

2.13 Notice of Special Meetings. Notice of the date, place and time of any special meeting of the Board shall be given to each director by the Chairman of the Board, the Chief Executive Officer, the Secretary or by the officer or one of the directors calling the meeting. Notice shall be duly given to each director (a) in person or by telephone at least twenty-four (24) hours in advance of the meeting, (b) by sending written notice by reputable overnight courier, telecopy, facsimile or other means of electronic transmission, or delivering written notice by hand, to such director’s last known business, home or means of electronic transmission address at least twenty-four (24) hours in advance of the meeting, or (c) by sending written notice by first-class mail to such director’s last known business or home address at least seventy-two (72) hours in advance of the meeting. A notice or waiver of notice of a meeting of the Board need not specify the purposes of the meeting.

2.14 Meetings by Conference Communications Equipment. Directors may participate in meetings of the Board or any committee thereof by means of conference telephone or other communications equipment by means of which all persons participating in the meeting can hear each other, and participation by such means shall constitute presence in person at such meeting.

2.15 Action by Consent. Any action required or permitted to be taken at any meeting of the Board or of any committee thereof may be taken without a meeting, if all members of the Board or committee, as the case may be, consent to the action in writing or by electronic transmission, and the writing or writings

or electronic transmission or transmissions are filed with the minutes of proceedings of the Board or committee thereof. Such filing shall be in paper form if the minutes are maintained in paper form and shall be in electronic form if the minutes are maintained in electronic form.

2.16 Committees. The Board may designate one or more committees, each committee to consist of one or more of the directors of the Corporation with such lawfully delegable powers and duties as the Board thereby confers, to serve at the pleasure of the Board. The Board may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. In the absence or disqualification of a member of a committee, the member or members of the committee present at any meeting and not disqualified from voting, whether or not such member or members constitute a quorum, may unanimously appoint another member of the Board to act at the meeting in the place of any such absent or disqualified member. Any such committee, to the extent provided in the resolution of the Board and subject to the provisions of law, shall have and may exercise all the powers and authority of the Board in the management of the business and affairs of the Corporation and may authorize the seal of the Corporation to be affixed to all papers which may require it; but no such committee shall have the power or authority to (i) approve or adopt, or recommend to the stockholders, any action or matter (other than the election or removal of directors) expressly required by the DGCL to be submitted to stockholders for approval, or (ii) adopt, amend or repeal any bylaw of the Corporation. Each such committee shall keep minutes and make such reports as the Board may from time to time request. Except as the Board may otherwise determine, any committee may make rules for the conduct of its business, but unless otherwise provided by the directors or in such rules, its business shall be conducted as nearly as possible in the same manner as is provided in these Bylaws for the Board. Except as otherwise provided in the Certificate of Incorporation, these Bylaws, or the resolution of the Board designating the committee, a committee may create one or more subcommittees, each subcommittee to consist of one or more members of the committee, and delegate to a subcommittee any or all of the powers and authority of the committee.

2.17 Compensation of Directors. Directors may be paid such compensation for their services and such reimbursement for expenses of attendance at meetings as the Board may from time to time determine. No such payment shall preclude any director from serving the Corporation or any of its parent or subsidiary entities in any other capacity and receiving compensation for such service.

4.2 Stock Certificates; Uncertificated Shares. The shares of the Corporation shall be represented by certificates, provided that the Board may provide by resolution or resolutions that some or all of any or all classes or series of the Corporation’s stock shall be uncertificated shares.

Each such certificate shall be signed in a manner that complies with Section 158 of the DGCL.

Each certificate for shares of stock which are subject to any restriction on transfer pursuant to the Certificate of Incorporation, these Bylaws, applicable securities laws or any agreement among any number of stockholders or among such holders and the Corporation shall have conspicuously noted on the face or back of the certificate either the full text of the restriction or a statement of the existence of such restriction.

If the Corporation shall be authorized to issue more than one class of stock or more than one series of any class, the powers, designations, preferences and relative participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights shall be set forth in full or summarized on the face or back of each certificate representing shares of such class or series of stock, provided that in lieu of the foregoing requirements there may be set forth on the face or back of each certificate representing shares of such class or series of stock a statement that the Corporation will furnish without charge to each stockholder who so requests the powers, designations, preferences and relative, participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights.

Within a reasonable time after the issuance or transfer of uncertificated shares, the Corporation shall send to the registered owner thereof a written notice containing the information required to be set forth or stated on certificates pursuant to Sections 151, 156, 202(a) or 218(a) of the DGCL or, with respect to Section 151 of DGCL, a statement that the Corporation will furnish without charge to each stockholder who so requests the powers, designations, preferences and relative participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights.

4.5 Record Date. In order that the Corporation may determine the stockholders entitled to notice of any meeting of stockholders or any adjournment thereof, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board, and which record date shall, unless otherwise required by law, not be more than sixty (60) nor less than ten (10) days before the date of such meeting. If the Board so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the Board, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board may fix a new record date for determination of stockholders entitled to vote at the adjourned meeting, and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance herewith at the adjourned meeting.

In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board may fix a record date, which shall not be more than sixty (60) days prior to such action.

Neither the business nor the purpose of any meeting need be specified in any such waiver. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened.

5.4 Voting of Securities. Except as the Board may otherwise designate, the Chief Executive Officer, the President or the Chief Financial Officer may waive notice, vote, consent, or appoint any person or persons to waive notice, vote or consent, on behalf of the Corporation, and act as, or appoint any person or persons to act as, proxy or attorney-in-fact for this Corporation (with or without power of substitution) with respect to, the securities of any other entity which may be held by this Corporation.

Article VII
Indemnification and Advancement

7.1 Power to Indemnify in Actions, Suits or Proceedings other than Those by or in the Right of the Corporation. Subject to Section 7.3, the Corporation shall indemnify, to the fullest extent permitted by Delaware law, as the same exists or may hereafter be amended, any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation) by reason of the fact that such person is or was a director or officer of the Corporation, or, while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another Corporation, partnership, joint venture, trust, employee benefit plan or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea or nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that such person’s conduct was unlawful.

7.2 Power to Indemnify in Actions, Suits or Proceedings by or in the Right of the Corporation. Subject to Section 7.3, the Corporation shall indemnify, to the fullest extent permitted by Delaware law, as the same exists or may hereafter be amended, any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that such person is or was a director or officer of the Corporation, or, while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another Corporation, partnership, joint venture, trust, employee benefit plan or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation; except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

A-138

TABLE OF CONTENTS

7.3 Authorization of Indemnification. Any indemnification under this Article VII (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director or officer is proper in the circumstances because such person has met the applicable standard of conduct set forth in Section 7.1 or Section 7.2, as the case may be. Such determination shall be made, with respect to a person who is a director or officer at the time of such determination, (i) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, or (ii) by a committee of such directors designated by a majority vote of such directors, even though less than a quorum, or (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion or (iv) by the stockholders. Such determination shall be made, with respect to former directors and officers, by any person or persons having the authority to act on the matter on behalf of the Corporation. To the extent, however, that a present or former director or officer of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding set forth in Section 7.1 or Section 7.2 or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith, without the necessity of authorization in the specific case.

7.4 Good Faith Defined. For purposes of any determination under Section 7.3, a person shall be deemed to have acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, or, with respect to any criminal action or proceeding, to have had no reasonable cause to believe such person’s conduct was unlawful, if such person’s action is based on good faith reliance on the records or books of account of the Corporation or another enterprise, or on information supplied to such person by the officers of the Corporation or another enterprise in the course of their duties, or on the advice of legal counsel for the Corporation or another enterprise or on information or records given or reports made to the Corporation or another enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Corporation or another enterprise. The term “another enterprise” as used in this Section 7.4 shall mean any other corporation or any partnership, joint venture, trust, employee benefit plan or other enterprise of which such person is or was serving at the request of the Corporation as a director, officer, employee or agent. The provisions of this Section 7.4 shall not be deemed to be exclusive or to limit in any way the circumstances in which a person may be deemed to have met the applicable standard of conduct set forth in Section 7.1 or 7.2, as the case may be.

7.5 Right of Claimant to Bring Suit. Notwithstanding any contrary determination in the specific case under Section 7.3, and notwithstanding the absence of any determination thereunder, if a claim under Sections 7.1 or 7.2 of the Article VII is not paid in full by the Corporation within (i) ninety (90) days after a written claim for indemnification has been received by the Corporation, or (ii) thirty (30) days after a written claim for an advancement of expenses has been received by the Corporation, the claimant may at any time thereafter (but not before) bring suit against the Corporation in the Court of Chancery in the State of Delaware to recover the unpaid amount of the claim, together with interest thereon, or to obtain advancement of expenses, as applicable. It shall be a defense to any such action brought to enforce a right to indemnification (but not in an action brought to enforce a right to an advancement of expenses) that the claimant has not met the standards of conduct which make it permissible under the DGCL (or other applicable law) for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation. Neither a contrary determination in the specific case under Section 7.3 nor the absence of any determination thereunder shall be a defense to such application or create a presumption that the claimant has not met any applicable standard of conduct. If successful, in whole or in part, the claimant shall also be entitled to be paid the expense of prosecuting such claim, including reasonable attorneys’ fees incurred in connection therewith, to the fullest extent permitted by applicable law.

7.6 Expenses Payable in Advance. Expenses, including without limitation attorneys’ fees, incurred by a current or former director or officer in defending any civil, criminal, administrative or investigative action, suit or proceeding shall be paid, to the fullest extent permitted by Delaware law as the same exists or may hereafter be amended, by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such current or former director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the Corporation as authorized in this Article VII.

TABLE OF CONTENTS

7.7 Nonexclusivity of Indemnification and Advancement of Expenses. The rights to indemnification and advancement of expenses provided by or granted pursuant to this Article VII shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under the Certificate of Incorporation, any agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding such office, it being the policy of the Corporation that, subject to Section 7.11, indemnification of the persons specified in Sections 7.1 and 7.2 shall be made to the fullest extent permitted by law. The provisions of this Article VII shall not be deemed to preclude the indemnification of any person who is not specified in Section 7.1 or 7.2 but whom the Corporation has the power or obligation to indemnify under the provisions of the DGCL, or otherwise.

7.8 Insurance. The Corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the Corporation would have the power or the obligation to indemnify such person against such liability under the provisions of this Article VII.

ENERGY VAULT HOLDINGS, INC.
2022 EQUITY INCENTIVE PLAN

ARTICLE 1. INTRODUCTION.

The Board adopted the Plan to become effective immediately, although no Awards may be granted prior to the Business Combination Date. The purpose of the Plan is to promote the long-term success of the Company and the creation of stockholder value by (a) encouraging Service Providers to focus on critical long-range corporate objectives, (b) encouraging the attraction and retention of Service Providers with exceptional qualifications and (c) linking Service Providers directly to stockholder interests through increased stock ownership. The Plan seeks to achieve this purpose by providing for Awards in the form of Options (which may beISOs or NSOs), SARs, Restricted Sharesand Restricted Stock Units. Capitalized terms used in this Plan are defined in Article 14.

ARTICLE 2. ADMINISTRATION.

2.1 General . The Plan may be administered by the Board or one or more Committees to which the Board (or an authorized Board committee) has delegated authority. If administration is delegated to a Committee, the Committee shall have the powers theretofore possessed by the Board, including, to the extent permitted by applicable law, the power to delegate to a subcommittee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to either the Board or the Administrator shall hereafter also encompass the Committee or subcommittee, as applicable). The Board may abolish the Committee’s delegation at any time and the Board shall at all times also retain the authority it has delegated to the Committee. The Administrator shall comply with rules and regulations applicable to it, including under the rules of any exchange on which the Common Shares are traded, and shall have the authority and be responsible for such functions as have been assigned to it.

2.2 Section 16. To the extent desirable to qualify transactions hereunder as exempt under Exchange Act Rule 16b-3, the transactions contemplated hereunder will be approved by the entire Board or a Committee of two or more “non-employee directors” within the meaning of Exchange Act Rule 16b-3.

2.3 Powers of Administrator. Subject to the terms of the Plan, and in the case of a Committee, subject to the specific duties delegated to the Committee, the Administrator shall have the authority to (a) select the Service Providers who are to receive Awards under the Plan, (b) determine the type, number, vesting requirements and other features and conditions of such Awards, (c) interpret the Plan and Awards granted under the Plan, (d) determine whether, when and to what extent an Award has become vested and/or exercisable and whether any performance-based vesting conditions have been satisfied, (e) make, amend and rescind rules relating to the Plan and Awards granted under the Plan, including rules relating to sub-plans established for the purposes of satisfying applicable foreign laws or for qualifying for favorable tax treatment under applicable foreign laws, (f) impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by a Participant of any Common Shares issued pursuant to an Award, including restrictions under an insider trading policy and restrictions as to the use of a specified brokerage firm for such resales, and (g) make all other decisions relating to the operation of the Plan and Awards granted under the Plan. In addition, with regard to the terms and conditions of Awards granted to Service Providers outside of the United States, the Administrator may vary from the provisions of the Plan (other than any requiring stockholder approval pursuant to Section 13.3) to the extent it determines it necessary and appropriate to do so.

2.4 Effect of Administrator’s Decisions. The Administrator’s decisions, determinations and interpretations shall be final and binding on all interested parties.

2.5 Governing Law. The Plan shall be governed by, and construed in accordance with, the laws of the State of Delaware (except its choice-of-law provisions).

ARTICLE 3. SHARES AVAILABLE FOR GRANTS.

3.1 Basic Limitation. Common Shares issued pursuant to the Plan may be authorized but unissued shares or treasury shares. The aggregate number of Common Shares issued under the Plan shall not exceed

C-2

TABLE OF CONTENTS

the sum of (a) 15,516,760 Common Shares, plus (b) up to 8,251,906 Common Shares subject to awards granted under the Predecessor Plans that are outstanding on the Business Combination Date and that subsequently are forfeited, expire or lapse unexercised or unsettled and Common Shares issued pursuant to awards granted under the Predecessor Plans that are outstanding on the Business Combination Date and that are subsequently forfeited to or reacquired by the Company, and (c) the additional Common Shares described in Articles 3.2 and 3.3. The Company shall reserve and keep available such number of Common Shares as will be sufficient to satisfy the requirements of the Plan. The numerical limitations in this Article 3.1 shall be subject to adjustment pursuant to Article 9.

3.2 Annual Increase in Shares. On the first day of each March during the term of the Plan, commencing on March 1, 2022 and ending on (and including) March 1, 2031, the aggregate number of Common Shares that may be issued under the Plan shall automatically increase by a number equal to the lesser of (a)4% of the total number of Common Shares actually issued and outstanding on the last day of the preceding month, or (b) a number of Common Shares determined by the Board.

3.3 Shares Returned to Reserve. To the extent that Options, SARs, Restricted Stock Units or other Awards are forfeited, cancelled or expire for any reason before being exercised or settled in full, the Common Shares subject to such Awards shall again become available for issuance under the Plan. If SARs are exercised or Restricted Stock Units are settled, then only the number of Common Shares (if any) actually issued to the Participant upon exercise of such SARs or settlement of such Restricted Stock Units, as applicable, shall reduce the number of Common Shares available under Article 3.1 and the balance shall again become available for issuance under the Plan. If Restricted Shares or Common Shares issued upon the exercise of Options are reacquired by the Company pursuant to a forfeiture provision, repurchase right or for any other reason, then such Common Shares shall again become available for issuance under the Plan. Common Shares applied to pay the Exercise Price of Options or to satisfy tax withholding obligations related to any Award shall again become available for issuance under the Plan. To the extent that an Award is settled in cash rather than Common Shares, the cash settlement shall not reduce the number of Shares available for issuance under the Plan.

3.4 Awards Not Reducing Share Reserve. To the extent permitted under applicable exchange listing standards, anydividend equivalents paid or credited under the Plan with respect to Restricted Stock Units shall not be applied against the number of Common Shares that may be issued under the Plan, whether or not such dividend equivalents are converted into Restricted Stock Units. In addition, Common Shares subject to Substitute Awards granted by the Company shall not reduce the number of Common Shares that may be issued under Article 3.1, nor shall shares subject to Substitute Awards again be available for Awards under the Plan in the event of any forfeiture, expiration or cash settlement of such Substitute Awards.

3.5 Code Section 422 and Other Limits. Subject to adjustment in accordance with Article 9:

(a) The grant date fair value of Awards granted to an Outside Director during any one fiscal year of the Company, together with the value of any cash compensation paid to the Outside Director during such fiscal year, may not exceed $750,000 (on a per-Director basis); provided however that the limitation that will apply in the fiscal year in which the Outside Director is initially appointed or elected to the Board shall instead be $1,000,000. For purposes of this limitation, the grant date fair value of an Award shall be determined in accordance with the assumptions that the Company uses to estimate the value of share-based payments for financial reporting purposes. For the sake of clarity, neither Awards granted, nor cash compensation paid, to an individual for his or her service as an Employee or Consultant, but not as an Outside Director, shall count towards this limitation.

(b) No more than 9,205,979 Common Shares (subject to adjustment pursuant to Article 9) may be issued under the Plan upon the exercise of ISOs.

ARTICLE 4. ELIGIBILITY.

4.1 Incentive Stock Options. Only Employees who are common-law employees of the Company, a Parent or a Subsidiary shall be eligible for the grant of ISOs. In addition, an Employee who owns more than 10% of the total combined voting power of all classes of outstanding stock of the Company or any of

C-3

TABLE OF CONTENTS

its Parents or Subsidiaries shall not be eligible for the grant of an ISO unless the additional requirements set forth in Code Section 422(c)(5) are satisfied.

4.2 Other Awards. Awards other than ISOs may be granted to both Employees and other Service Providers.

ARTICLE 5. OPTIONS.

5.1 Stock Option Agreement. Each grant of an Option under the Plan shall be evidenced by a Stock Option Agreement between the Optionee and the Company. Such Option shall be subject to all applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan. The Stock Option Agreement shall specify whether the Option is intended to be an ISO or an NSO. The provisions of the various Stock Option Agreements entered into under the Plan need not be identical.

5.2 Number of Shares. Each Stock Option Agreement shall specify the number of Common Shares subject to the Option, which number shall adjust in accordance with Article 9.

5.3 Exercise Price. Each Stock Option Agreement shall specify the Exercise Price, which shall not be less than 100% of the Fair Market Value of a Common Share on the date of grant. The preceding sentence shall not apply to an Option that is a Substitute Award granted in a manner that would satisfy the requirements of Code Section 409A and, if applicable, Code Section 424(a).

5.4 Exercisability and Term. Each Stock Option Agreement shall specify the date or event when all or any installment of the Option is to become vested and/or exercisable. The vesting and exercisability conditions applicable to the Option may include service-based conditions, performance-based conditions, such other conditions as the Administrator may determine, or any combination of such conditions. The Stock Option Agreement shall also specify the term of the Option; provided that, except to the extent necessary to comply with applicable foreign law, the term of an Option shall in no event exceed 10 years from the date of grant. A Stock Option Agreement may provide for accelerated vesting and/or exercisability upon certain specified events and may provide for expiration prior to the end of its term in the event of the termination of the Optionee’s service.

5.5 Death of Optionee. After an Optionee’s death, any vested and exercisable Options held by such Optionee may be exercised by his or her beneficiary or beneficiaries. Each Optionee may designate one or more beneficiaries for this purpose by filing the prescribed form with the Company. A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Optionee’s death. If no beneficiary was designated or if no designated beneficiary survives the Optionee, then any vested and exercisable Options held by the Optionee may be exercised by his or her estate.

5.6 Modification or Assumption of Options. Within the limitations of the Plan, the Administrator may modify, reprice, extend or assume outstanding options or may accept the cancellation of outstanding options (whether granted by the Company or by another issuer) in return for the grant of new Options for the same or a different number of shares and at the same or a different exercise price or in return for the grant of a different type of Award. The foregoing notwithstanding, no modification of an Option shall, without the consent of the Optionee, materially impair his or her rights or obligations under such Option.

5.7 Buyout Provisions. The Administrator may at any time (a) offer to buy out for a payment in cash or cash equivalents an Option previously granted or (b) authorize an Optionee to elect to cash out an Option previously granted, in either case at such time and based upon such terms and conditions as the Administrator shall establish.

5.8 Payment for Option Shares. The entire Exercise Price of Common Shares issued upon exercise of Options shall be payable in cash or cash equivalents at the time when such Common Shares are purchased. In addition, the Administrator may, in its sole discretion and to the extent permitted by applicable law, accept payment of all or a portion of the Exercise Price through any one or a combination of the following forms or methods:

(a) Subject to any conditions or limitations established by the Administrator, by surrendering, or attesting to the ownership of, Common Shares that are already owned by the Optionee with a value on the date of surrender equal to the aggregate exercise price of the Common Shares as to which such Option will be exercised;

C-4

TABLE OF CONTENTS

(b) By delivering (on a form prescribed by the Company) an irrevocable direction to a securities broker approved by the Company to sell all or part of the Common Shares being purchased under the Plan and to deliver all or part of the sales proceeds to the Company;

(c) Subject to such conditions and requirements as the Administrator may impose from time to time, through a net exercise procedure; or

(d) Through any other form or method consistent with applicable laws, regulations and rules.

ARTICLE 6. STOCK APPRECIATION RIGHTS.

6.1 SAR Agreement. Each grant of a SAR under the Plan shall be evidenced by a SAR Agreement between the Optionee and the Company. Such SAR shall be subject to all applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan. The provisions of the various SAR Agreements entered into under the Plan need not be identical.

6.2 Number of Shares. Each SAR Agreement shall specify the number of Common Shares to which the SAR pertains, which number shall adjust in accordance with Article 9.

6.3 Exercise Price. Each SAR Agreement shall specify the Exercise Price, which shall in no event be less than 100% of the Fair Market Value of a Common Share on the date of grant. The preceding sentence shall not apply to a SAR that is a Substitute Award granted in a manner that would satisfy the requirements of Code Section 409A.

6.4 Exercisability and Term. Each SAR Agreement shall specify the date when all or any installment of the SAR is to become vested and exercisable. The vesting and exercisability conditions applicable to the SAR may include service-based conditions, performance-based conditions, such other conditions as the Administrator may determine, or any combination thereof. The SAR Agreement shall also specify the term of the SAR; provided that except to the extent necessary to comply with applicable foreign law, the term of a SAR shall not exceed 10 years from the date of grant. A SAR Agreement may provide for accelerated vesting and exercisability upon certain specified events and may provide for expiration prior to the end of its term in the event of the termination of the Optionee’s service.

6.5 Exercise of SARs. Upon exercise of a SAR, the Optionee (or any person having the right to exercise the SAR after his or her death) shall receive from the Company (a) Common Shares, (b) cash or (c) a combination of Common Shares and cash, as the Administrator shall determine. The amount of cash and/or the Fair Market Value of Common Shares received upon exercise of SARs shall, in the aggregate, not exceed the amount by which the Fair Market Value (on the date of surrender) of the Common Shares subject to the SARs exceeds the Exercise Price. If, on the date when a SAR expires, the Exercise Price is less than the Fair Market Value on such date but any portion of such SAR has not been exercised or surrendered, then such SAR shall automatically be deemed to be exercised as of such date with respect to such portion. A SAR Agreement may also provide for an automatic exercise of the SAR on an earlier date.

6.6 Death of Optionee. After an Optionee’s death, any vested and exercisable SARs held by such Optionee may be exercised by his or her beneficiary or beneficiaries. Each Optionee may designate one or more beneficiaries for this purpose by filing the prescribed form with the Company. A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Optionee’s death. If no beneficiary was designated or if no designated beneficiary survives the Optionee, then any vested and exercisable SARs held by the Optionee at the time of his or her death may be exercised by his or her estate.

6.7 Modification or Assumption of SARs. Within the limitations of the Plan, the Administrator may modify, reprice, extend or assume outstanding stock appreciation rights or may accept the cancellation of outstanding stock appreciation rights (whether granted by the Company or by another issuer) in return for the grant of new SARs for the same or a different number of shares and at the same or a different exercise price or in return for the grant of a different type of Award. The foregoing notwithstanding, no modification of a SAR shall, without the consent of the Optionee, materially impair his or her rights or obligations under such SAR.

C-5

TABLE OF CONTENTS

ARTICLE 7. RESTRICTED SHARES.

7.1 Restricted Stock Agreement. Each grant of Restricted Shares under the Plan shall be evidenced by a Restricted Stock Agreement between the recipient and the Company. Such Restricted Shares shall be subject to all applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan. The provisions of the various Restricted Stock Agreements entered into under the Plan need not be identical.

7.2 Payment for Awards. Restricted Shares may be sold or awarded under the Plan for such consideration as the Administrator may determine, including (without limitation) cash, cash equivalents, property, cancellation of other equity awards, promissory notes, past services and future services, and such other methods of payment as are permitted by applicable law.

7.3 Vesting Conditions. Each Award of Restricted Shares may or may not be subject to vesting and/or other conditions as the Administrator may determine. Vesting shall occur, in full or in installments, upon satisfaction of the conditions specified in the Restricted Stock Agreement. Vesting conditions may include service-based conditions, performance-based conditions, such other conditions as the Administrator may determine, or any combination thereof. A Restricted Stock Agreement may provide for accelerated vesting upon certain specified events.

7.4 Voting and Dividend Rights. The holders of Restricted Shares awarded under the Plan shall have the same voting, dividend and other rights as the Company’s other stockholders, unless the Administrator otherwise provides. A Restricted Stock Agreement, however, may require that any cash dividends paid on Restricted Shares (a) be accumulated and paid when such Restricted Shares vest, or (b) be invested in additional Restricted Shares. Such additional Restricted Shares shall be subject to the same conditions and restrictions as the shares subject to the Award with respect to which the dividends were paid. In addition, unless the Administrator provides otherwise, if any dividends or other distributions are paid in Common Shares, such Common Shares shall be subject to the same restrictions on transferability and forfeitability as the Restricted Shares with respect to which they were paid.

7.5 Modification or Assumption of Restricted Shares. Within the limitations of the Plan, the Administrator may modify or assume outstanding Restricted Shares or may accept the cancellation of outstanding restricted shares (whether granted by the Company or by another issuer) in return for the grant of new Restricted Shares for the same or a different number of shares or in return for the grant of a different type of Award. The foregoing notwithstanding, no modification of Restricted Shares shall, without the consent of the Participant, materially impair his or her rights or obligations under such Restricted Shares.

ARTICLE 8. RESTRICTED STOCK UNITS.

8.1 Restricted Stock Unit Agreement. Each grant of Restricted Stock Units under the Plan shall be evidenced by a Restricted Stock Unit Agreement between the recipient and the Company. Such Restricted Stock Units shall be subject to all applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan. The provisions of the various Restricted Stock Unit Agreements entered into under the Plan need not be identical.

8.2 Payment for Awards. To the extent that an Award is granted in the form of Restricted Stock Units, no cash consideration shall be required of the Award recipients.

8.3 Vesting Conditions. Each Award of Restricted Stock Units may or may not be subject to vesting, as determined by the Administrator. Vesting shall occur, in full or in installments, upon satisfaction of the conditions specified in the Restricted Stock Unit Agreement. Vesting conditions may include service-based conditions, performance-based conditions, such other conditions as the Administrator may determine, or any combination thereof. A Restricted Stock Unit Agreement may provide for accelerated vesting upon certain specified events.

8.4 Voting and Dividend Rights. The holders of Restricted Stock Units shall have no voting rights. Prior to settlement or forfeiture, Restricted Stock Unitsawarded under the Plan may, at the Administrator’s discretion, provide for a right to dividend equivalents. Such right entitles the holder to be credited with an

C-6

TABLE OF CONTENTS

amount equal to all cash dividends paid on one Common Share while the Restricted Stock Unit is outstanding. Dividend equivalents may be converted into additional Restricted Stock Units. Settlement of dividend equivalents may be made in the form of cash, in the form of Common Shares, or in a combination of both. Prior to distribution, any dividend equivalents shall be subject to the same conditions and restrictions as the Restricted Stock Units to which they attach.

8.5 Form and Time of Settlement of Restricted Stock Units. Settlement of vested Restricted Stock Units may be made in the form of (a) cash, (b) Common Shares or (c) any combination of both, as determined by the Administrator. The actual number of Restricted Stock Units eligible for settlement may be larger or smaller than the number included in the original Award, based on predetermined performance factors. Methods of converting Restricted Stock Units into cash may include (without limitation) a method based on the average value of Common Shares over a series of trading days. Vested Restricted Stock Units shall be settled in such manner and at such time(s) as specified in the Restricted Stock Unit Agreement. Until an Award of Restricted Stock Units is settled, the number of such Restricted Stock Units shall be subject to adjustment pursuant to Article 9.

8.6 Death of Recipient. Any Restricted Stock Units that become payable after the recipient’s death shall be distributed to the recipient’s beneficiary or beneficiaries. Each recipient of Restricted Stock Units under the Plan may designate one or more beneficiaries for this purpose by filing the prescribed form with the Company. A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Award recipient’s death. If no beneficiary was designated or if no designated beneficiary survives the Award recipient, then any Restricted Stock Units that become payable after the recipient’s death shall be distributed to the recipient’s estate.

8.7 Modification or Assumption of Restricted Stock Units. Within the limitations of the Plan, the Administrator may modify or assume outstanding restricted stock units or may accept the cancellation of outstanding restricted stock units (whether granted by the Company or by another issuer) in return for the grant of new Restricted Stock Units for the same or a different number of shares or in return for the grant of a different type of Award. The foregoing notwithstanding, no modification of a Restricted Stock Unit shall, without the consent of the Participant, materially impair his or her rights or obligations under such Restricted Stock Unit.

8.8 Creditors’ Rights. A holder of Restricted Stock Units shall have no rights other than those of a general creditor of the Company. Restricted Stock Units represent an unfunded and unsecured obligation of the Company, subject to the terms and conditions of the applicable Restricted Stock Unit Agreement.

ARTICLE 9. ADJUSTMENTS; DISSOLUTIONS AND LIQUIDATIONS; CORPORATE TRANSACTIONS.

9.1 Adjustments. In the event of a subdivision of the outstanding Common Shares, a declaration of a dividend payable in Common Shares, a combination or consolidation of the outstanding Common Shares (by reclassification or otherwise) into a lesser number of Common Shares or any other increase or decrease in the number of issued Common Shares effected without receipt of consideration by the Company, proportionate adjustments shall be made tothe following:

(a) The number and kind of shares available for issuance under Article 3, including the numerical share limits in Articles 3.1 and 3.5;

(b) The number and kind of shares covered by each outstanding Option, SAR and Restricted Stock Unit; and/or

(c) The Exercise Price applicable to each outstanding Option and SAR, and the repurchase price, if any, applicable to Restricted Shares.

In the event of a declaration of an extraordinary dividend payable in a form other than Common Shares in an amount that has a material effect on the price of Common Shares, a recapitalization, a spin-off or a similar occurrence, the Administrator may make such adjustments as it, in its sole discretion, deems appropriate to the foregoing. Any adjustment in the number of shares subject to an Award under this Article 9.1 shall be rounded down to the nearest whole share, although the Administrator in its sole discretion

C-7

TABLE OF CONTENTS

may make a cash payment in lieu of a fractional share. Except as provided in this Article 9, a Participant shall have no rights by reason of any issuance by the Company of stock of any class or securities convertible into stock of any class, any subdivision or consolidation of shares of stock of any class, the payment of any stock dividend or any other increase or decrease in the number of shares of stock of any class.

9.2 Dissolution or Liquidation. To the extent not previously exercised or settled, Options, SARs and Restricted Stock Units shall terminate immediately prior to the dissolution or liquidation of the Company.

9.3 Corporate Transactions. In the event that the Company is a party to a merger, consolidation, or a Change in Control (other than one described in Article 14.7(d)), all Common Shares acquired under the Plan and all Awards outstanding on the effective date of the transaction shall be treated in the manner described in the definitive transaction agreement (or, in the event the transaction does not entail a definitive agreement to which the Company is party, in the manner determined by the Administrator, with such determination having final and binding effect on all parties), which agreement or determination need not treat all Awards (or portions thereof) in an identical manner. Unless an Award Agreement provides otherwise, the treatment specified in the transaction agreement or by the Administrator may include (without limitation) one or more of the following with respect to each outstanding Award:

(a) The continuation of such outstanding Award by the Company (if the Company is the surviving entity);

(b) The assumption of such outstanding Award by the surviving entity or its parent, provided that the assumption of an Option or a SAR shall comply with applicable tax requirements;

(c) The substitution by the surviving entity or its parent of an equivalent award for such outstanding Award (including, but not limited to, an award to acquire the same consideration paid to the holders of Common Shares in the transaction), provided that the substitution of an Option or a SAR shall comply with applicable tax requirements;

(d) In the case of an Option or SAR, the cancellation of such Award without payment of any consideration. An Optionee shall be able to exercise his or her outstanding Option or SAR, to the extent such Option or SAR is then vested or becomes vested as of the effective time of the transaction, during a period of not less than five full business days preceding the closing date of the transaction, unless (i) a shorter period is required to permit a timely closing of the transaction and (ii) such shorter period still offers the Optionee a reasonable opportunity to exercise such Option or SAR;

(e) The cancellation of such Award and a payment to the Participant with respect to each share subject to the portion of the Award that is vested or becomes vested as of the effective time of the transaction equal to the excess of (A) the value, as determined by the Administrator in its absolute discretion, of the property (including cash) received by the holder of a Common Share as a result of the transaction, over (if applicable) (B) the per-share Exercise Price of such Award (such excess,if any, the “Spread”). Such payment shall be made in the form of cash, cash equivalents, or securities of the surviving entity or its parent having a value equal to the Spread. In addition, any escrow, holdback, earn-out or similar provisions in the transaction agreement may apply to such payment to the same extent and in the same manner as such provisions apply to the holders of Common Shares. If the Spread applicable to an Award (whether or not vested) is zero or a negative number, then the Award may be cancelled without making a payment to the Participant. In the event that an Award is subject to Code Section 409A, the payment described in this clause (e) shall be made on the settlement date specified in the applicable Award Agreement, provided that settlement may be accelerated in accordance with Treasury Regulation Section 1.409A-3(j)(4); or

(f) The assignment of any reacquisition or repurchase rights held by the Company in respect of an Award of Restricted Shares to the surviving entity or its parent, with corresponding proportionate adjustments made to the price per share to be paid upon exercise of any such reacquisition or repurchase rights.

Unless an Award Agreement provides otherwise, each outstanding Award held by a Participant who remains a Service Provider as of the effective time of a merger, consolidation or Change in Control (other than one described in Article 14.7(d)) (a “Current Participant”) shall become fully vested and, if applicable, exercisable (with any performance-based vesting conditions applicable to an Award deemed achieved at

C-8

TABLE OF CONTENTS

100% of target levels) immediately prior to the effective time of the transaction. However, the prior sentence shall not apply, and an outstanding Award shall not become vested and, if applicable, exercisable, if and to the extent the Award is continued, assumed or substituted as provided for in clauses (a), (b) or (c) above. In addition, the prior two sentences shall not apply to an Award held by a Participant who is not a Current Participant, unless an Award Agreement provides otherwise or unless the Company and the acquirer agree otherwise.

For avoidance of doubt, the Administrator shall have the discretion, exercisable either at the time an Award is granted or at any time while the Award remains outstanding, to provide for the acceleration of vesting upon the occurrence of a Change in Control, whether or not the Award is to be assumed or replaced in the transaction, or in connection with a termination of the Participant’s service following a transaction.

Any action taken under this Article 9.3 shall either preserve a Award’s status as exempt from Code Section 409A or comply with Code Section 409A.

ARTICLE 10. OTHER AWARDS.

Subject in all events to the limitations under Article 3 above as to the number of Common Shares available for issuance under this Plan, the Company may grant other forms of Awards not specifically described herein and may grant awards under other plans or programs, where such awards are settled in the form of Common Shares issued under this Plan. Such Common Shares shall be treated for all purposes under the Plan like Common Shares issued in settlement of Restricted Stock Units and shall, when issued, reduce the number of Common Shares available under Article 3.

ARTICLE 11. LIMITATION ON RIGHTS.

11.1 Retention Rights. Neither the Plan nor any Award granted under the Plan shall be deemed to give any individual a right to remain a Service Provider. The Company and its Parents, Subsidiaries and Affiliates reserve the right to terminate the service of any Service Provider at any time, with or without cause, subject to applicable laws, the Company’s certificate of incorporation and by-laws and a written employment agreement (if any).

11.2 Stockholders’ Rights. Except as set forth in Article 7.4 or 8.4 above, a Participant shall have no dividend rights, voting rights or other rights as a stockholder with respect to any Common Shares covered by his or her Award prior to the time when a stock certificate for such Common Shares is issued or, if applicable, the time when he or she becomes entitled to receive such Common Shares by filing any required notice of exercise and paying any required Exercise Price. No adjustment shall be made for cash dividends or other rights for which the record date is prior to such time, except as expressly provided in the Plan.

11.3 Regulatory Requirements. Any other provision of the Plan notwithstanding, the obligation of the Company to issue Common Shares under the Plan shall be subject to all applicable laws, rules and regulations and such approval by any regulatory body as may be required. The Company reserves the right to restrict, in whole or in part, the delivery of Common Shares pursuant to any Award prior to the satisfaction of all legal requirements relating to the issuance of such Common Shares, to their registration, qualification or listing or to an exemption from registration, qualification or listing. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed necessary by the Company’s counsel to be necessary to the lawful issuance and sale of any Common Shares hereunder, will relieve the Company of any liability in respect of the failure to issue or sell such Common Shares as to which such requisite authority will not have been obtained.

11.4 Transferability of Awards. The Administrator may, in its sole discretion, permit transfer of an Award in a manner consistent with applicable law. Unless otherwise determined by the Administrator, Awards shall be transferable by a Participant only by (a) beneficiary designation, (b) a will or (c) the laws of descent and distribution; provided that, in any event, an ISO may only be transferred by will or by the laws of descent and distribution and may be exercised during the lifetime of the Optionee only by the Optionee or by the Optionee’s guardian or legal representative

11.5 Recoupment Policy. All Awards granted under the Plan, all amounts paid under the Plan and all Common Shares issued under the Plan shall be subject to recoupment, clawback or recovery by the

C-9

TABLE OF CONTENTS

Company in accordance with applicable law and with Company policy (whenever adopted) regarding same, whether or not such policy is intended to satisfy the requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act, the Sarbanes-Oxley Act, or other applicable law, as well as any implementing regulations and/or listing standards thereunder.

11.6 Other Conditions and Restrictions on Common Shares. Any Common Shares issued under the Plan shall be subject to such forfeiture conditions, rights of repurchase, rights of first refusal, other transfer restrictions and such other terms and conditions as the Administrator may determine. Such conditions and restrictions shall be set forth in the applicable Award Agreement and shall apply in addition to any restrictions that may apply to holders of Common Shares generally. In addition, Common Shares issued under the Plan shall be subject to such conditions and restrictions imposed either by applicable law or by Company policy, as adopted from time to time, designed to ensure compliance with applicable law or laws with which the Company determines in its sole discretion to comply including in order to maintain any statutory, regulatory or tax advantage.

ARTICLE 12. TAXES.

12.1 General. It is a condition to eachAward under the Plan that a Participant or his or her successor shall make arrangements satisfactory to the Company for the satisfaction of any federal, state, local or foreign withholding tax obligations that arise in connection with any Award granted under the Plan. The Company shall not be required to issue any Common Shares or make any cash payment under the Plan unlesssuch obligations are satisfied.

12.2 Share Withholding. To the extent that applicable law subjects a Participant to tax withholding obligations, the Administrator may permit such Participant to satisfy all or part of such obligations by having the Company withhold all or a portion of any Common Shares that otherwise would be issued to him or her or by surrendering all or a portion of any Common Shares that he or she previously acquired. Such Common Shares shall be valued on the date when they are withheld or surrendered. Any payment of taxes by assigning Common Shares to the Company may be subject to restrictions including any restrictions required by theSEC, accounting or other rules.

12.3 Section 409A Matters. Except as otherwise expressly set forth in an Award Agreement, it is intended that Awards granted under the Plan either be exempt from, or comply with, the requirements of Code Section 409A. To the extent an Award is subject to Code Section 409A (a “409A Award”), the terms of the Plan, the Award and any written agreement governing the Award shall be interpreted to comply with the requirements of Code Section 409A so that the Award is not subject to additional tax or interest under Code Section 409A, unless the Administrator expressly provides otherwise. A 409A Award shall be subject to such additional rules and requirements as specified by the Administrator from time to time in order for it to comply with the requirements of Code Section 409A. In this regard, if any amount under a 409A Award is payable upon a “separation from service” to an individual who is considered a “specified employee” (as each term is defined under Code Section 409A), then no such payment shall be made prior to the date that is the earlier of (i) six months and one day after the Participant’s separation from service or (ii) the Participant’s death, but only to the extent such delay is necessary to prevent such payment from being subject to Code Section 409A(a)(1).

12.4 Limitation on Liability. Neither the Company nor any person serving as Administrator shall have any liability to a Participant in the event an Award held by the Participant fails to achieve its intended characterization under applicable tax law.

ARTICLE 13. FUTURE OF THE PLAN.

13.1 Term of the Plan. The Plan, as set forth herein, shall become effective on the date of its adoption by the Board, subject to approval of the Company’s stockholders under Article 13.3 below. The Plan shall terminate automatically 10 years after the date when the Board adopted the Plan.

Attention: Special Committee of the Board of Directors

Members of the Special Committee of the Board of Directors:

We understand that Novus Capital Corporation II (“Novus”) intends to enter into a Business Combination Agreement and Plan of Reorganization (the “Agreement”) by and among Novus, NCII Merger Corp. (“Merger Sub”) and Energy Vault, Inc. (“Energy Vault”). We have been advised that pursuant to the Agreement, among other things (i) Merger Sub will merge with Energy Vault (the “Merger”), (ii) Energy Vault will survive the Merger as a wholly owned subsidiary of Novus, and (iii) the outstanding shares of common stock, par value $0.0001 per share (“Energy Vault Common Stock”), of Energy Vault (including shares of preferred stock of Energy Vault (“Energy Vault Preferred Stock”) that have been converted to shares of Energy Vault Common Stock (other than shares of Energy Vault Series C Preferred Stock)) and the outstanding shares of Energy Vault Series C Preferred Stock will be converted into the right to receive, in the aggregate, a number of shares of Class A Common Stock, par value $0.0001 per share (“Novus Class A Common Stock”), of Novus (the “Aggregate Closing Merger Consideration”), (iv) immediately prior to the Merger, Novus will assume obligations of Energy Vault related to amounts funded for unissued shares of Series C preferred stock of Energy Vault (the “Energy Vault Interim Period Convertible Preferred Obligation”) and (v) in connection with the Merger, the principal and accrued interest payable in respect of the Energy Vault Interim Period Convertible Preferred Obligation will be converted into a number of shares (in the aggregate, the “Aggregate Energy Vault Interim Period Convertible Preferred Conversion Consideration” and, together with the Aggregate Closing Merger Consideration, the “Aggregate Closing Consideration”) of Novus Class A Common Stock. We also have been advised that (i) prior to the Merger, all outstanding shares of Energy Vault Preferred Stock (other than shares of Energy Vault Series C Preferred Stock) will be converted into shares of Energy Vault Common Stock and (ii) following the Merger, certain former holders of Energy Vault equity will have the right to be issued additional shares of Novus Class A Common Stock (the “Earnout Shares”) in accordance with and subject to the conditions set forth in the Agreement.

You have requested that Cassel Salpeter & Co., LLC render an opinion (this “Opinion”) to the Special Committee (the “Committee”) of the Board of Directors of Novus (the “Board”) as to whether, as of the date of this Opinion, the Aggregate Closing Consideration to be issued by Novus in connection with the Merger pursuant to the Agreement is fair, from a financial point of view, to Novus. For purposes of our analyses and this Opinion we have, at your direction, assumed that (i) each share of Novus Class A Common Stock has a value equal to $10.00 per share (with such $10.00 value being based on the Novus’s initial public offering and Novus’s approximate cash per outstanding share of Novus Class A Common Stock (excluding, for the avoidance of doubt, the dilutive impact of outstanding shares of Class B Common Stock, par value $0.0001 per share (“Novus Class B Common Stock” and, together with the Novus Class A Common Stock, the “Novus Common Stock”), of Novus or any warrants to purchase Novus Common Stock and notwithstanding the price at which shares of Energy Vault Series C Preferred Stock have been or will be issued)), (ii) the Aggregate Closing Consideration will consist of 114,760,000 shares of Novus Class A Common Stock, and (iii) the Aggregate Closing Consideration has a value equal to $1,147,600,000. In addition, for purposes of our analyses and this Opinion, at your direction, we did not evaluate or take into account the Earnout Shares.

In arriving at this Opinion, we have made such reviews, analyses, and inquiries as we have deemed necessary and appropriate under the circumstances. Among other things, we have:

•

This Opinion only addresses whether, as of the date hereof, the Aggregate Closing Consideration to be issued by Novus in connection with the Merger pursuant to the Agreement is fair, from a financial point of view, to Novus. It does not address any other terms, aspects, or implications of the Merger, the Agreement or any related or other transaction or agreement, including, without limitation, (i) the Amended and Restated Registration Rights Agreement to be entered into by Novus, certain stockholders of Energy Vault and certain stockholders of Novus; the Lock-Up Agreement to be entered into by certain stockholders of Energy Vault and certain stockholders of Novus; the subscription agreements with certain investors pursuant to which such investors will agree to purchase shares of Novus Common Stock at a purchase price of $10.00 per share in a private placement or placements (the “Private Placements”); the Sponsor Support Agreement to be entered into certain stockholders of Novus; or the Sponsor Restricted Stock Agreement to be entered into by certain stockholders of Novus, (ii) the Earnout Shares, (iii) the fairness of the portion of the Aggregate Closing Consideration to be issued to holders of Energy Vault Common Stock or the fairness of the portion of the Aggregate Closing Consideration to be issued to holders of Energy Vault Series C Preferred Stock or holders of the Energy Vault Interim Period Convertible Preferred Obligations taken separately or relative to one another, (iv) the fairness of the Merger, or all or anyportion of the Aggregate Closing Consideration, to any security holders of Novus, Energy Vault or any other person or any creditors or other constituencies of Novus, Energy Vault or any other person, (v) the appropriate capital structure of Novus or whether Novus should be issuing debt or equity securities or a combination of both in connection with the Merger, (vi) any capital raising or financing transaction contemplated by Novus or Energy Vault, including, without limitation, the Private Placements, nor (vii) the fairness of the amount or nature, or any other aspect, of any compensation or consideration payable to or received by any officers, directors, or employees of any parties to the Merger, or any class of such persons, relative to the Aggregate Closing Consideration or otherwise. We are not expressing any view or opinion as to what the value of shares of Novus Common Stock or any other security of Novus actually will be when issued in connection with the Merger or the prices at which Novus Common Stock, Energy Vault Common Stock, Energy Vault Preferred Stock or any other security of Novus or Energy Vault may trade, be purchased or sold at any time.

This Opinion does not address the relative merits of the Merger as compared to any alternative transaction or business strategy that might exist for Novus, or the merits of the underlying decision by the Committee, the Board or Novus to engage in or consummate the Merger. The financial and other terms of the Merger were determined pursuant to negotiations between the parties to the Agreement and were not determined by or pursuant to any recommendation from us. In addition, we were not authorized to, and we did not, solicit indications of interest from third parties regarding a potential transaction involving Novus.

In arriving at this Opinion, we have, with your consent, relied upon and assumed, without independently verifying, the accuracy and completeness of all of the financial and other information that was supplied or otherwise made available to us or available from public sources, and we have further relied upon the assurances of Novus’s and Energy Vault’s management that they were not aware of any facts or circumstances that would make any such information inaccurate or misleading.

We are not legal, tax, accounting, environmental, regulatory, technology or science advisors, and we do not express any views or opinions as to any legal, tax, accounting, environmental, regulatory, technology or science matters relating to Novus, Energy Vault, the Merger, or otherwise. We understand and have assumed that the Committee has obtained or will obtain such advice as it deems necessary or appropriate from qualified legal, tax, accounting, environmental, regulatory, technology, science and other professionals, that such advice is sound and reasonable and that the Committee and Novus has acted or will act in accordance therewith.

Energy Vault has advised us and we have with your agreement assumed that the Projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of Energy Vault with respect to the future financial performance of Energy Vault, and we have assumed, at your direction, that the Projections provide a reasonable basis upon which to analyze and evaluate Energy Vault and form an opinion. At your direction, we have used and relied upon the Company Projections for purposes of our analyses and this Opinion. We express no view or opinion with respect to the Projections or the assumptions on which they are based. We have not evaluated the solvency or creditworthiness of Novus, Energy Vault or any other party to the Merger, the fair value of Novus, Energy Vault or any of their respective assets or liabilities, or whether Novus, Energy Vault or any other party to the Merger is paying or receiving reasonably equivalent value in connection with the Merger under any applicable foreign, state, or federal laws relating to bankruptcy, insolvency, fraudulent transfer, or similar matters, nor have we evaluated, in any way, the ability of Novus, Energy Vault or any other party to the Merger to pay its obligations when they come due. We have not physically inspected Novus’s or Energy Vault’s properties or facilities and have not made or obtained any evaluations or appraisals of Novus’s or Energy Vault’s assets or liabilities (including any contingent, derivative, or off-balance-sheet assets and liabilities). We have not attempted to confirm whether Novus and Energy Vault have good title to their respective assets. Our role in reviewing any information was limited solely to performing such reviews as we deemed necessary to support our own advice and analysis and was not on behalf of the Committee, the Board, Novus, or any other party.

We have assumed, with your consent, that the Merger will be consummated in a manner that complies in all respects with applicable foreign, federal, state, and local laws, rules, and regulations and that, in the course of obtaining any regulatory or third party consents, approvals, or agreements in connection with the Merger, no delay, limitation, restriction, or condition will be imposed that would have an adverse effect on Novus, Energy Vault or the Merger. We also have assumed, with your consent, that the final executed form of the Agreement will not differ in any material respect from the draft we have reviewed and that the Merger will be consummated on the terms set forth in the Agreement, without waiver, modification, or amendment of any term, condition, or agreement thereof that is material to our analyses or this Opinion. We have also assumed that the representations and warranties of the parties to the Agreement contained therein are true and correct and that each such party will perform all of the covenants and agreements to be performed by it under the Agreement. We offer no opinion as to the contractual terms of the Agreement or the likelihood that the conditions to the consummation of the Merger or the issuance of the Earnout Shares set forth in the Agreement will be satisfied. You have also advised us, and we have assumed, that for U.S. federal tax income purposes the Merger shall qualify as a reorganization within the meaning of Section 368 of the Internal Revenue Code of 1986, as amended.

We have not been requested to, and did not, (a) initiate or participate in any discussions or negotiations with respect to the Transaction, the securities, assets, businesses or operations of Novus, Energy Vault or any other party, or any alternatives to the Merger, (b) negotiate the terms of the Merger, or (c) advise the Committee, the Board, Novus or any other party with respect to alternatives to the Merger. Our analyses and this Opinion are necessarily based upon market, economic, and other conditions as they exist on, and could be evaluated as of, the date hereof. Accordingly, although subsequent developments may arise that would otherwise affect this Opinion, we do not assume any obligation to update, review, or reaffirm this

TABLE OF CONTENTS

Opinion to you or any other person or otherwise to comment on or consider events occurring or coming to our attention after the date hereof.

This Opinion is addressed to the Committee for the use and benefit of the members of the Committee (in their capacities as such) and, as requested by the Committee, for the use and benefit of the members of the Board (in their capacities as such) in connection with the Committee’s and, as applicable, the Board’s evaluation of the Merger. This Opinion is not intended to and does not constitute advice or a recommendation to any of Novus’s stockholders or any other security holders as to how such holder should vote or act with respect to any matter relating to the Merger or otherwise, including, without limitation, whether any such stockholder should redeem their shares or whether any party should participate in the Private Placements.

We will receive a fee for rendering this Opinion, no portion of which is contingent upon the completion of the Merger. In addition, Novus has agreed to reimburse certain of our expenses and to indemnify us and certain related parties for certain liabilities that may arise out of our engagement or the rendering of this Opinion. In accordance with our policies and procedures, a fairness committee was not required to, and did not, approve the issuance of this Opinion.

Based upon and subject to the foregoing, it is our opinion that, as of the date of this Opinion, the Aggregate Closing Consideration to be issued by Novus in connection with the Merger pursuant to the Agreement is fair, from a financial point of view, to Novus.

Very truly yours,

/s/ Cassel Salpeter & Co., LLC

PART II
INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

Section 145(a) of the DGCL provides, in general, that a corporation may indemnify any person who was or is a party to or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), because he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding, if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

Section 145(b) of the DGCL provides, in general, that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor because the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made with respect to any claim, issue or matter as to which he or she shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances of the case, he or she is fairly and reasonably entitled to indemnity for such expenses that the Court of Chancery or other adjudicating court shall deem proper.

Section 145(g) of the DGCL provides, in general, that a corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify the person against such liability under Section 145 of the DGCL.

In connection with the Business Combination, Energy Vault will enter into indemnification agreements with each of its directors and executive officers. These agreements will provide that Energy Vault will indemnify each of its directors and such officers to the fullest extent permitted by law and its charter and its bylaws.

Energy Vault will also maintain a general liability insurance policy, which will cover certain liabilities of directors and officers of Energy Vault arising out of claims based on acts or omissions in their capacities as directors or officers.

Certain portions of this Exhibit will be excluded because they are not material and are of the type that the registrant treats as private or confidential.

Filed herewith.

†

Certain of the exhibits and schedules to this Exhibit have been omitted in accordance with Regulation S-K Item 601. The Registrant agrees to furnish a copy of all omitted exhibits and schedules to the SEC upon its request.

Item 22. Undertakings

The undersigned registrant hereby undertakes:

A. To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

II-6

TABLE OF CONTENTS

B. That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

C. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

D. That, for the purpose of determining liability under the Securities Act to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

E. That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

F. That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

G. That every prospectus (i) that is filed pursuant to paragraph (F) immediately preceding, or (ii) that purports to meet the requirements of section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

H. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or

II-7

TABLE OF CONTENTS

paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

I. The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

J. To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
