In addition, in all the markets where the Company operates its customers’ systems, the Company has agreements to manage the energy storage systems using the Athena platform to participate in energy markets and to share the revenue from such market participation.


The Company delivers its battery hardware and software-enabled services through its Athena platform to its customers. The Company’s hardware and recurring software-enabled services mitigate customer energy costs through services such as time-of-use and demand charge management optimization and by aggregating the dispatch of energy through a network of virtual power plants. The resulting network created by the Company’s growing customer base increases grid resilience and reliability through the real-time processing of market-based demand cycles, energy prices and other factors in connection with the deployment of renewable energy resources to such customers. Additionally, the Company’s energy storage solutions support renewable energy generation by alleviating grid intermittency issues and thereby reducing customer dependence on traditional, fossil fuel resources. As of December 31, 2020, Athena has accumulated over 20 million runtime hours, which is equivalent to more than 2,200 years of operational experience, across hundreds of sites and customers in several utility territories across the U.S., Canada and Chile.

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 auditor 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 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. 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 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.

Liquidity and Capital Resources

As of September 30, 2020, the Company had approximately $1.8 million in its operating bank account and working capital of approximately $1.8 million.

The Company’s liquidity needs to date have been satisfied through a capital contribution of $25,000 from the Sponsor to purchase the Founder Shares (as defined below), the loan of up to $300,000 under the Note (see Note 4), and the net proceeds from the consummation of the Private Placement not held in the Trust Account. The Company fully repaid the Note on August 20, 2020. In addition, in order to finance transaction costs in connection with a Business Combination, the Company’s officers, directors and initial stockholders may, but are not obligated to, provide the Company Working Capital Loans (see Note 4). To-date, there have been no borrowings under any Working Capital Loans.

Based on the foregoing, management believes that the Company will have sufficient working capital and borrowing capacity from the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors to meet its needs through the earlier of the consummation of a Business Combination or one year from this filing. Over this time period, the Company will be using these funds for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.

Management continues to evaluate the impact of the COVID-19 pandemic and has concluded that the specific impact is not readily determinable as of the date of the balance sheet. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Note 2—Summary of Significant Accounting Policies

Use of Estimates

The preparation ofconsolidated 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, disclosuresthe disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. MakingThe Company bases its estimates requires managementon historical experience and on various other assumptions believed 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 actualbe reasonable. Actual results could differ significantly from those estimates.

Cashestimates and Cash Equivalents

such differences could be material to the financial position and results of operations.

Significant estimates and assumptions reflected in these unaudited condensed consolidated financial statements include, but are not limited to, depreciable life of energy systems; the amortization of financing obligations; deferred commissions and contract fulfillment costs; the valuation of energy storage systems, internally developed software, and asset retirement obligations; and the fair value of equity instruments, equity-based instruments, warrant liabilities and embedded derivatives.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000, and investments held in Trust Account. At September 30, 2020, the Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.

Fair Value of Financial Instruments

Fair

Assets and liabilities recorded at fair value is defined asin the priceunaudited condensed consolidated financial statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would behave received forin connection with the sale of an assetthe assets or paid forin connection with the transfer of a liability,the liabilities in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tierIn connection with measuring the fair value hierarchy,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).

Hierarchical levels which prioritizesare directly related to the amount of subjectivity associated with the inputs used in measuring fair value.

The hierarchy givesto the highest priority to unadjustedvaluation of these assets or liabilities are as follows:

Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities (Levelthat the Company has the ability to access as of the measurement date.
Level 2 — Inputs other than quoted prices included within Level 1 measurements)that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data.
Level 3 — Unobservable inputs for the asset or liability only used when there is little, if any, market activity for the asset or liability at the measurement date.
This hierarchy requires the Company to use observable market data, when available, and to minimize the lowest priority touse of unobservable inputs (Level 3 measurements). These tiers include:

Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets;

Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and

Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

In some circumstances, the inputs used to measurewhen determining fair value. Assets and liabilities measured at fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorizedare classified in itstheir entirety in the fair value hierarchy based on the lowest level of input that is significant to their fair value measurement. The Company’s assessment of the significance of a specific input to the fair value measurement.

As of September 30, 2020, the carrying values of cash, accounts payable, accrued expenses,measurement in its entirety requires management to make judgments and franchise tax payable approximate their fair values dueconsider factors specific to the short-term nature of the instruments. The Company’s portfolio of investments held in the Trust Account is comprised of investments in U.S. Treasury securities with an original maturity of 185 daysasset or less or investments in money market funds that invest in U.S. government securities, or a combination thereof. The fair value for trading securities is determined using quoted market prices in active markets.

Offering Costs Associated with the Initial Public Offering

Offering costs consisted of underwriting, legal, accounting, and other costs incurred that were directly related to the Initial Public Offering and that were charged to stockholders’ equity upon the completion of the Initial Public Offering.

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 ASC Topic 480 “Distinguishing Liabilities from Equity.” Class A common stock subject to mandatory redemption (if any) is classified as a liability instrument and measured at fair value. Conditionally redeemable Class A common stock (including Class A 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 the Company’s control) is classified as temporary equity. At all other times, Class A 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 the occurrence of uncertain future events. Accordingly, at September 30, 2020, 36,683,412 shares of Class A common stock subject to possible redemption is presented as temporary equity, outside of the stockholders’ equity section of the Company’s unaudited condensed balance sheet.

Income Taxes

The Company follows the asset and liability method of accounting for income taxes. Deferred taxFinancial assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement 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. As of September 30, 2020, the Company had deferred tax assets of approximately $55,000, which had a full valuation allowance recorded against them. The deferred tax assets are comprised of approximately $26,000 of organization and start-up costs and of approximately $29,000 of projected net operating loss for the current tax year.

For tax 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. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of September 30, 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.

Net Income (Loss) Per Common Share

Net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common stock outstanding during the periods. The Company has not considered the effect of the warrants sold in the Initial Public Offering and the Private Placement to purchase up to an aggregate of 19,967,302 shares of the Company’s Class A common stock in the calculation of the diluted income per share, since their inclusion would be anti-dilutive under the treasury stock method.

The Company’s unaudited condensed statements of operations include a presentation of income (loss) per share for common stock subject to redemption in a manner similar to the two-class method of income (loss) per share. Net income per common share, basic and diluted for Class A common stock is calculated by dividing the gain on investment (net), dividends and interest held in Trust Account of approximately $19,000 for the three and nine months ended September 30, 2020, net of applicable taxes available to be withdrawn from the Trust Account of approximately $19,000 for the three and nine months ended September 30, 2020, resulting in net income of $0 for the three months and nine ended September 30, 2020, by the weighted average number of Class A common stock outstanding for each period. Net loss per share, basic and diluted for Class B common stock is calculated by dividing the net loss of approximately $374,000 and $377,000 for the three and nine months ended September 30, 2020, respectively, less income attributable to Class A common stock of $0 for each period, by the weighted average number of Class B common stock outstanding for the period.

Recent Accounting Pronouncements

Management does not believe that any recently issued, but not yet effective, accounting pronouncement if currently adopted would have a material effect on the Company’s financial statements.

Note 3—Initial Public Offering

On August 20, 2020, the Company consummated its Initial Public Offering of 35,000,000 Units at $10.00 per Unit, generating gross proceeds of $350.0 million, and incurring offering costs of approximately $20.0 million, inclusive of approximately $12.3 million in deferred underwriting commissions. On August 26, 2020, the Company consummated the sale of 3,358,504 Units at the Initial Public Offering price at $10.00 per Unit pursuant to the notice of partial exercise from the underwriters, generating additional gross proceeds of approximately $33.6 million, and incurring additional offering costs of approximately $1.8 million, inclusive of approximately $1.2 million in deferred underwriting commissions.

Each Unit consists of one share of Class A common stock (such shares of Class A common stock included in the Units being offered, the “Public Shares”), and one-third of one redeemable warrant (each, a “Public Warrant”). Each whole Public Warrant entitles the holder to purchase one share of Class A common stock at a price of $11.50 per share, subject to adjustment (see Note 6).

Note 4—Related Party Transactions

Founder Shares

On November 8, 2018, the Sponsor purchased 2,875,000 shares (the “Founder Shares”) of the Company’s Class B common stock, par value $0.0001 per share, for an aggregate price of $25,000. On July 13, 2020, the Company effected a stock split resulting in the Sponsor holding 10,062,500 Founder Shares. All shares and the associated amounts have been retroactively restated to reflect the aforementioned stock split. On July 29, 2020, the Sponsor transferred 40,000 Founder Shares to each of Desirée Rogers and C. Park Shaper, the Company’s independent director nominees. The initial stockholders agreed to forfeit up to 1,312,500 Founder Shares to the extent that the over-allotment option is not exercised in full by the underwriters, so that the Founder Shares would represent 20% of the outstanding shares after the Initial Public Offering. The underwriters partially exercised their over-allotment option on August 26, 2020, with the remaining portion of the over-allotment option expiring at the conclusion of the 45-day option period. As a result, an aggregate of 472,874 Founder Shares were forfeited upon the expiration of the over-allotment option.

The Founder Shares will automatically convert into Class A common stock on a one-for-one basis at the time of the Company’s initial Business Combination and are subject to certain transfer restrictions, as described below. 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 sold in the Initial Public Offering and related to the closing of the initial 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 the 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 the Business Combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the Business Combination).

The initial stockholders agreed, subject to limited exceptions, not to transfer, assign or sell any of their Founder Shares until the earlier to occur of: (A) one year after the completion of the initial Business Combination or (B) subsequent to the initial Business Combination, (x) if the last sale price of the Class A common stock equals or exceeds $12.00 per share (as adjusted for share splits, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial 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 common stock for cash, securities or other property.

Private Placement Warrants

Simultaneously with the closing of the Initial Public Offering, the Company consummated the Private Placement of 6,733,333 Private Placement Warrants at a price of $1.50 per Private Placement Warrant to the Sponsor, generating gross proceeds of $10.1 million. In connection with the consummation of the sale of additional Units pursuant to the underwriters’ over-allotment option, on August 26, 2020, the Company sold an additional 447,801 Private Placement Warrants to the Sponsor, generating additional gross proceeds of approximately $0.7 million.

Each Private Placement Warrant is exercisable for one share of Class A common stock at a price of $11.50 per share. A portion of the proceeds from the sale of the Private Placement Warrants will be added to the proceeds from the Initial Public Offering to be held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable and exercisable on a cashless basis so long as they are held by the Sponsor or its permitted transferees.

The Sponsor and the Company’s officers and directors have agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants until 30 days after the completion of the initial Business Combination.

Related Party Reimbursements and Loans

The Company’s Sponsor has agreed to loan the Company up to $300,000 to cover expenses related to the Initial Public Offering pursuant to a promissory note, dated November 8, 2018 and later amended on July 10, 2020 (the “Note”). This loan is non-interest bearing and payable upon the completion of the Initial Public Offering. In 2018 and 2019, the Company borrowed approximately $182,000 under the Note and repaid approximately $125,000 when it temporary halted the Initial Public Offering in September 2019. The Company recapitalized and continued in July 2020, and borrowed an additional of $235,000 under the Note. The Company fully repaid the remaining balance the Note of approximately $292,000 on August 20, 2020.

In September 2020, the Company reimbursed affiliates of the Sponsor for costs incurred of approximately $113,000.

In addition, 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 officers and directors 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 is not completed, the Company may use a portion of the 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 lenders’ discretion, up to $1.5 million 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. As of September 30, no Working Capital Loan was outstanding.

Administrative Service Agreement

Commencing on the date that the Company’s securities were first listed on the NYSE, the Company agreed to pay an affiliate of the Sponsor of total $10,000 per month for office space, utilities, secretarial support and administrative services. Upon completion of the initial Business Combination or the liquidation, the Company will cease paying these monthly fees. The Company incurred approximately $20,000 in administrative expenses under the agreement, which is recognized in the accompanying unaudited condensed statements of operations for both the three and nine months ended September 30, 2020 within general and administrative expenses – related party.

Registration Rights

The holders of Founder Shares, Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans, if any, are entitled to registration rights (in the case of the Founder Shares, only after conversion of such shares into Class A common stock) pursuant to the registration and shareholder rights agreement. These holders will be entitled to certain demand and “piggyback” registration rights. However, the registration and shareholder rights agreement provides that the Company will not permit any registration statement filed under the Securities Act to become effective until the termination of the applicable lock-up period for the securities to be registered. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Of the 10,062,500 shares of Class B common stock outstanding, up to 1,312,500 shares were subject to forfeiture to the Company by the Sponsor for no consideration to the extent that the underwriters’ over-allotment option is not exercised in full or in part, so that the initial stockholders would collectively own 20.0% of the Company’s issued and outstanding common stock after the Initial Public Offering. The underwriters partially exercised their over-allotment option on August 26, 2020, with the remaining portion of the over-allotment option expiring at the conclusion of the 45-day option period. As a result, an aggregate of 472,874 Founder Shares were forfeited upon the expiration of the over-allotment option.

Common stockholders of record are entitled to one vote for each share held on all matters to be voted on by stockholders. Holders of the Class A common stock and holders of the Class B common stock will vote together as a single class on all matters submitted to a vote of our stockholders except as required by law.

Preferred Stock — The Company is authorized to issue 1,000,000 shares of preferred stock, with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors.

The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination or (b) 12 months from the closing of the Initial Public Offering; provided in each case that the Company has an effective registration statement under the Securities Act covering the Class A common stock issuable upon exercise of the Public Warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their Public Warrants on a cashless basis and such cashless exercise is exempt from registration under the Securities Act). 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 a registration statement for the registration, under the Securities Act, of the Class A common stock issuable upon exercise of the Public Warrants. The Company will use its commercially reasonable efforts to cause the same to become effective and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the Public Warrants in accordance with the provisions of the warrant agreement. If a registration statement covering the Class A common stock issuable upon exercise of the warrants is not effective by the sixtieth (60th) day after the closing of the initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption.

·if the closing price of the Class A ordinary shares for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which we send the notice of redemption to the warrant holders is less than $18.00 per share (as adjusted), the Private Placement Warrants must also be concurrently called for redemption on the same terms as the outstanding Public Warrants, as described above.

If and when the Public 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.

The exercise price and number of ordinary shares issuable upon exercise of the Public Warrants may be adjusted in certain circumstances, including in the event of a share dividend, or recapitalization, reorganization, merger or consolidation. However, except as described below, the Public Warrants will not be adjusted for issuance of ordinary shares at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the warrants. If the Company has not completed a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of 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 the respect to such warrants. Accordingly, the warrants may expire worthless.

The Private Placement Warrants will be identical to the Public Warrants underlying the Units being sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A ordinary 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 be non-redeemable (except as described above under “Redemption of Warrants when the price per Class A ordinary share equals or exceeds $10.00”) 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 under all redemption scenarios by the Company and exercisable by such holders on the same basis as the Public Warrants.

Note 7—Fair Value Measurements

The following table presents information about the Company’s assets that are measured at fair value on a recurring basis as of September 30, 2021 and December 31, 2020 include cash and indicatescash equivalents, short-term investments and warrant liabilities.

Recently Adopted Accounting Standards
In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement. The amendments applicable to the Company on the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be prospectively applied in the initial fiscal year of adoption. All other amendments applicable to the Company should be applied retrospectively to all periods presented upon their effective date. The Company adopted ASU 2018-13 as of January 1, 2020. The Company’s disclosures related to its level 3 financial instruments were not materially impacted for the periods presented. See Note 5, Fair Value Measurements, for more information.

In August 2018, the FASB issued ASU 2018-15, Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”). The intent of this pronouncement is to align the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software as defined in ASC 350-40.

implementation costs related to a cloud computing arrangement will be amortized over the term of the arrangement and all capitalized implementation amounts will be required to be presented in the same line items of the financial statements as the related hosting fees. ASU 2018-15 is effective for public and private companies’ fiscal years beginning after December 15, 2019, and December 15, 2020, respectively, and interim periods within those fiscal years, with early adoption permitted. The Company adopted ASU 2018-15 as of January 1, 2021. The adoption did not have a material effect on the Company’s unaudited condensed consolidated financial statements.
Recently Issued Accounting Standards
In June 2016, the FASB issued ASU 2016-13, Financial instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and subsequent related ASUs, which amends the guidance on the impairment of financial instruments by requiring measurement and recognition of expected credit losses for financial assets held. This ASU is effective for public and private companies’ fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019, and December 15, 2022, respectively. The Company expects to adopt ASU 2016-13 under the private company transition guidance beginning January 1, 2023 and is currently assessing the effect, if any, the guidance will have on the Company’s unaudited condensed consolidated financial statements.
In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. ASU 2019-12 will be effective for public entities for interim and annual periods beginning after December 15, 2020, with early adoption permitted. ASU 2019-12 will be effective for private entities for annual periods beginning after December 15, 2021, and interim periods beginning after December 15, 2020, with early adoption permitted. The Company plans to adopt ASU 2019-12 for the fiscal year beginning January 1, 2022 and is currently assessing the effect, if any, the guidance will have on the Company's unaudited condensed consolidated financial statements.
3.REVENUE
The Company recognizes revenue through 2 types of arrangements with customers, host customer arrangements and partnership arrangements as described below.

Host Customer Arrangements

Host customer contracts are generally entered into with commercial entities that have traditionally relied on power supplied directly from the grid. Host customer arrangements consist of a promise to provide energy optimization services through the Company’s proprietary SaaS platform coupled with a dedicated energy storage system owned and controlled by the Company throughout the term of the contract. The host customer does not obtain legal title to, or ownership of the dedicated energy storage system at any point in time. The host customer is the end consumer of the energy that directly benefits from the energy optimization services provided by the Company. The term for the Company’s contracts with host customers generally ranges from 5 to 10 years, which may include certain renewal options to extend the initial contract term or certain termination options to reduce the initial contract term.
Although the Company installs an energy storage system at the host customer site in order to provide the energy optimization services, the Company directs how and for what purpose the asset is used through the operation of its SaaS platform and, as such, retains control of the energy storage system; therefore, the contract does not contain a lease. The Company determines the various energy optimization services provided throughout the term of the contract, which may include services such as remote monitoring, performance reporting, preventative maintenance and other ancillary services necessary for the safe and reliable operation of the energy storage system, are part of a combined output of energy optimization services and the Company provides a single distinct combined performance obligation representing a series of distinct days of services.
The Company determines the transaction price at the outset of the arrangement, primarily based on the contractual payment terms dictated by the contract with the customer. Fees charged to customers for energy optimization services generally consist of recurring fixed monthly payments throughout the term of the contract. In certain arrangements, the transaction price may include incentive payments that are earned by the host customer from utility companies in relation to the services provided by the Company. Under such arrangements, the rights to the incentive payments are assigned by the host customer to the Company. These incentives may be in the form of fixed upfront payments, variable monthly payments, or annual performance-based payments over the first five years of the customer contract term. Incentive payments may be contingent on approval from utility companies or actual future performance of the energy storage system.

STEM, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)
Substantially all of the Company’s arrangements provide customers the unilateral ability to terminate for convenience prior to the conclusion of the stated contractual term or the contractual term is shorter than the estimated benefit period, which the Company has determined to be 10 years based on the estimated useful life of the underlying energy storage systems and the period over which the customer can benefit from the energy optimization services utilizing such energy storage systems. In these instances, the Company determined that upfront incentive payments received from its customers represent a material right that is, in effect, an advance payment for future energy optimization services to be recognized throughout the estimated benefit period. In contracts where the customer does not have the unilateral ability to terminate for convenience without a penalty during the estimated benefit period, the Company determined the upfront incentive payments do not represent a material right for services provided beyond the initial contractual period and are therefore a component of the initial transaction price. The Company revisits its estimate of the benefit period each reporting period. The Company’s contracts with host customers do not contain a significant financing component.

The Company transfers control of its energy optimization services to its customers continuously throughout the term of the contract (a stand-ready obligation) and revenue is recognized ratably as control of these services is transferred to its customers, in an amount that reflects the consideration the Company expects to be contractually entitled to in exchange for its services. Monthly incentive payments based on the performance of the energy storage system are allocated to the distinct month in which they are earned because the terms of the payments relate specifically to the outcome from transferring the distinct time increment (month) of service and because such amounts reflect the fees to which the Company expects to be entitled for providing energy optimization services each period, consistent with the allocation objective. Annual variable performance- based payments are estimated at the inception in the transaction price using the expected value method, which takes into consideration historical experience, current contractual requirements, specific known market events and forecasted energy storage system performance patterns, and the Company recognizes such payments ratably using a time-based measure of progress of days elapsed over the term of the contract to the extent that it is probable that a significant reversal of the cumulative revenue recognized will not occur in a future period. At the end of each reporting period, the Company reassesses its estimate of the transaction price. The Company does not begin recognition of revenue until the energy storage system is live (i.e., provision of energy optimization services has commenced) or, as it relates to incentive payments, when approval has been received from the utility company, if later.
Partnership Arrangements
Partnership arrangements consist of promises to transfer inventory in the form of an energy storage system to a “solar plus storage” project developer and separately provide energy optimization services as described previously to the ultimate owner of the project after the developer completes the installation of the project. Under partnership arrangements, the Company’s customer is the solar plus storage project developer. The customer obtains legal title to along with ownership and control of the inventory upon delivery and the customer is responsible for the installation of the project. Once installation of the project is complete, the owner of the solar plus storage project provides energy to the end consumer through a separate contractual arrangement directly with the end consumer. The term for the Company’s contracts with customers under partnership arrangements generally ranges from 10 to 20 years.
The Company determined the promise to deliver the inventory as a component of the solar plus storage project for which the customer is responsible to develop is a separate and distinct performance obligation from the promise to provide energy optimization services.
The Company determines the transaction price at the outset of the arrangement, primarily based on the contractual payment terms dictated by the contract with the customer. Fees charged for the sale of inventory generally consist of fixed fees payable upon or shortly after successful delivery to the customer. Fees charged to customers for energy optimization services consist of recurring fixed monthly payments throughout the term of the contract. The Company is responsible for designing, procuring, delivering and ensuring the proper components are provided in accordance with the requirements of the contract. Although the inventory is purchased by the Company from a third-party manufacturer, the Company determined it obtains control of the inventory prior to delivery to the customer and is the principal in the arrangement. The Company is fully responsible for responding to and correcting any customer issues related to the delivery of the inventory. The Company holds title and assumes all risks of loss associated with the inventory until the customer accepts the inventory. The Company is primarily responsible for fulfilling the delivery of the inventory to the customer, assumes substantial inventory risks and has discretion in the pricing charged to the customer. The Company has not entered into any partnership arrangements where it is not the principal in the transaction.

The Company allocates revenue between the hardware and energy storage services performance obligations based on the standalone selling price of each performance obligation. The standalone selling price for the hardware is established based on observable pricing. The standalone selling price for the energy optimization services is established using a residual value approach due to the significant variability in the services provided to each individual customer based on the specific requirements of each individual project and the lack of observable standalone sales of such services. The Company’s partnership arrangements do not contain a significant financing component.
The Company transfers control of the inventory upon delivery and simultaneous transfer of title to the customer. The Company transfers control of its energy optimization services to its customers continuously throughout the term of the contract (a stand-ready obligation), which does not commence until the customer successfully completes the installation of the project. As a result, the time frame between when the Company transfers control of the inventory to the customer upon delivery is generally several months, and can be in excess of one year, before the Company is required to perform any subsequent energy optimization services. Revenue is recognized ratably as control of these services is transferred to its customers based on a time-based output measure of progress of days elapsed over the term of the contract, in an amount that reflects the consideration the Company expects to be entitled to in exchange for its services.
In some partnership arrangements, the Company charges shipping fees for the inventory. The Company accounts for shipping as a fulfillment activity, since control transfers to the customer after the shipping is complete and includes such amounts within cost of revenue.

The Company periodically reviews the available-for-sale securities for other-than-temporary impairment loss. The Company considers factors such as the duration, severity and the reason for the decline in value, the potential recovery period and its intent to sell. For debt securities, it also considers whether (i) it is more likely than not that the Company will be required to sell the securities before recovery of their amortized cost basis, and (ii) the amortized cost basis cannot be recovered as a result of credit losses. During the nine months ended September 30, 2021, the Company did not recognize any other-than-temporary impairment losses. All securities with unrealized losses have been in a loss position for less than 12 months.
5.FAIR VALUE MEASUREMENTS
Fair value accounting is applied for all financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. At September 30, 2021 and December 31, 2020, the carrying amount of accounts receivable, other current assets, accounts payable, and accrued and other current liabilities approximated their estimated fair value due to their relatively short maturities. There were no assets or liabilities classified as Level 3 as of September 30, 2021.

The Company’s money market funds are classified as Level 1 because they are valued using quoted market prices. The Company’s short-term investments consist of available-for-sale securities and are classified as Level 2 because their value is based on valuations using significant inputs derived from or corroborated by observable market data. The convertible preferred stock warrant liabilities are defined as Level 3 in the fair value hierarchy as the valuations are based on significant unobservable inputs, which reflect the Company’s own assumptions incorporated in valuation techniques used to determine fair value; further discussion of these assumptions is set forth below. There were no transfers into or out of Level 3 of the fair value hierarchy during the periods presented.
Convertible Preferred Stock Warrant Liabilities
As discussed in Note 9 - Warrants, upon effectiveness of the Merger, substantially all of the outstanding convertible preferred stock warrants were converted into shares of Class A common stock of Stem. As such, the associated warrant liability was reclassified to additional paid-in-capital upon the Merger and was no longer an outstanding Level 3 financial instrument as of September 30, 2021. The fair value of the convertible preferred stock warrants as of September 30, 2020 was determined using the Black-Scholes method as well as a discount for lack of marketability. Black-Scholes inputs used to value the warrants are based on information from purchase agreements and within valuation techniques thatreports prepared by an independent third party for the Company. Inputs include exercise price, volatility, fair value of common or preferred stock, expected dividend rate and risk-free interest rate.
The key assumptions used for the valuation of the preferred stock warrant liabilities upon remeasurement were as follows:

time, subsequently amended. The purpose of this revolving loan agreement was to finance the Company’s purchase of hardware for its various energy storage system projects. As of the beginning of 2020, the agreement had a total revolving loan capacity of $45.0 million that bore fixed interest at 10% with a maturity date of June 2020.

In May 2020, concurrent with the 2020 Credit Agreement discussed below, the Company entered into an amendment to the revolving loan agreement, which reduced the loan capacity to $35.0 million and extended the maturity date to May 2021. The amendment increased the fixed interest rate for any borrowings outstanding more than nine months to 14% thereafter. Additionally, under the original terms of the revolving loan agreement, the Company was able to finance 100% of the value of the hardware purchased up to the total loan capacity. The amendment reduced the advance rate to 85%, with an additional reduction to 70% in August 2020. The amendment was accounted for as a modification of the debt, which did not have a material impact on the unaudited condensed consolidated financial statements. As of December 31, 2020, the Company had $7.4 million outstanding under the revolving loan agreement. In April 2021, the Company repaid the remaining outstanding balance of this facility with the proceeds received from the Merger. The facility was terminated after the repayment in April 2021.
Term Loan Due to SPE Member
In December 2018, the Company entered into a term loan in the amount of $13.3 million with an affiliate of a member of certain SPEs with the Company. As of the beginning of 2020, the term loan bore fixed interest of 12.5% on the outstanding principal balance with a final balloon payment of $3.0 million due at the maturity date of June 30, 2020. In May 2020, the

Term Loan Due to Former Non-Controlling Interest Holder
In June 2018, the Company acquired the outstanding member interests of an entity controlled by the Company for $8.1 million. The Company uses inputsfinanced this acquisition by entering into a term loan agreement with the noncontrolling member bearing fixed interest of 4.5% per quarter (18.0% per annum) on the outstanding principal balance. The loan required fixed quarterly payments throughout the term of the loan, which was scheduled to be paid in full by April 1, 2026.
In May 2020, the Company amended the term loan and, using the proceeds from the 2020 Credit Agreement discussed below, prepaid $1.5 million of principal and interest on the note, of which $1.0 million was towards the outstanding principal balance, thereby reducing the fixed quarterly payment due to the lender. In relation to this amendment, the Company was required to issue warrants for 400,000 shares of common stock resulting in a discount to the term loan of $0.2 million. As of December 31, 2020, the outstanding balance was $5.8 million. In April 2021, the Company repaid the remaining outstanding balance of this facility with the proceeds received from the Merger. Upon prepayment of this facility, the Company incurred $2.6 million in prepayment penalties that were recorded to loss on extinguishment of debt in the Company’s statement of operations. The facility was terminated after the repayment in April 2021.
2020 Credit Agreement
In May 2020, the Company entered into a credit agreement (“2020 Credit Agreement”) with a new lender that provided the Company with proceeds of $25.0 million to provide the Company with access to working capital towards the purchase of energy storage system equipment. The 2020 Credit Agreement has a maturity date of the earlier of (1) May 2021, (2) the maturity date of the revolving loan agreement, or (3) the maturity date of the convertible promissory notes discussed below. The loan bore interest of 12% per annum, of which 8% was paid in cash and 4% added back to principal of the loan balance every quarter. The Company used a portion of the proceeds towards payments associated with existing debt as previously discussed. As of December 31, 2020, the outstanding balance was $25.6 million. In April 2021, the Company repaid the remaining outstanding balance of this facility with the proceeds received from the Merger. Upon prepayment of this facility, the Company incurred $1.4 million in prepayment penalties that were recorded to loss on extinguishment of debt in the Company’s statement of operations. The facility was terminated after the repayment in April 2021.
2021 Credit Agreement
In January 2021, the Company, through a wholly owned Canadian entity, entered into a credit agreement to provide a total of $2.7 million towards the financing of certain energy storage systems. The credit agreement is structured on a non-recourse basis and the system will be operated by the Company. The credit agreement has a stated interest of 5.45% and a maturity date of June 2031. The Company received an advance under the credit agreement of $1.8 million in January 2021. The repayment of advances received under this credit agreement is determined by the lender based on the proceeds generated by the Company through the operation of the underlying energy storage systems. As of September 30, 2021, and December 31, 2020, the outstanding balance was $1.9 million and zero, respectively. The Company was in compliance with all covenants contained in the 2021 Credit Agreement as of September 30, 2021.

Q1 2021 Convertible Notes
In January 2021, the Company issued and sold convertible promissory notes (the “Q1 2021 Convertible Notes”) under the same terms as the then existing Convertible Promissory Notes to determinevarious investors with aggregate gross proceeds of $1.1 million. The Company evaluated the conversion option within the Q1 2021 Convertible Notes and determined the effective conversion price was beneficial to the note holders. As such, the Company recorded a beneficial conversion feature (“BCF”) related to the issuance of the Q1 2021 Convertible Notes based on the difference between the effective conversion rate and the fair value of its investments.

Transfers to/from Levels 1, 2, and 3 are recognized at the endstock into which it was convertible, limited by the amount of the reportingaggregate gross proceeds. The BCF resulted in a $1.1 million discount to the Q1 2021 Convertible Notes with an increase to additional paid in capital. The Company accreted the discount in connection with the BCF as interest expense over the term of the Q1 2021 Convertible Notes using the effective interest rate method.

The Plans permit net settlement of vested awards, pursuant to which the award holder forfeits a portion of the vested award to satisfy the purchase price (in the case of stock options), the holder’s withholding tax obligation, if eventsany, or transactions occurring through November 13, 2020,both. When the holder net settles the tax obligation, the Company pays the amount of the withholding tax to the U.S. government in cash, which is accounted for as an adjustment to additional paid-in-capital.

Options under the Plans generally expire after 10 years. Under the Plans, the Compensation Committee of the Board determines when the options granted will become exercisable. Options granted under the Plans generally vest 1/4 one year from the grant date and then 1/48 each month over the following three years and are exercisable for 10 years from the date of the financial statementsgrant. The Plans allow for exercise of unvested options with repurchase rights over the restricted common stock issued at the original exercise price.

Contingencies
The Company is party to various legal proceedings from time to time. A liability is accrued when a loss is both probable and can be reasonably estimated. Management believes that the probability of a material loss with respect to any currently pending legal proceeding is remote. However, litigation is inherently uncertain and it is not possible to definitively predict the ultimate disposition of any of these proceedings. The Company does not believe that there are any pending legal proceedings or other loss contingencies that will, either individually or in the aggregate, have a material adverse impact on the Company’s unaudited condensed consolidated financial statements.

Commitments
In June 2021, the Company entered into an agreement to lease 23,533 square feet of office space in San Francisco, California. The lease commenced on September 23, 2021 and expires on February 28, 2029. The lease agreement does not contemplate options to extend or reduce the non-cancelable lease term. Base rent is $160,809 per month with escalating payments. On September 23, 2021, the Company recognized or disclosed.

Overview

We are a blank check company incorporated in Delaware on October 29, 2018 for the purpose of effecting a merger, capital stock exchange, asset acquisition, share purchase, reorganization or similar business combination filed by Star Peak on March 30, 2021, the Form 10-K/A filed by Star Peak with the SEC on April 26, 2021, and our Forms 8-K filed with or furnished to the SEC.

Our sponsor is Star Peak Sponsor LLC, a Delaware limited liability company (our “Sponsor”).

Our registration statement for our Initial Public Offering (the “Initial Public Offering”) became effective on August 17, 2020.  On August 20, 2020, we consummated the Initial Public Offering of 35,000,000 units (the “Units” and, with respect to the Class A common stock included in the Units being offered, the “Public Shares”) at $10.00 per Unit, generating gross proceeds of $350.0 million, and incurring offering costs of approximately $20.0 million, inclusive of approximately $12.3 million in deferred underwriting commissions. On August 26, 2020, we consummated the sale of an additional 3,358,504 Units at the Initial Public Offering price at $10.00 per Unit pursuant to the notice of partial exercise from the underwriters, generating additional gross proceeds of approximately $33.6 million, and incurring additional offering costs of approximately $1.8 million, inclusive of an additional approximately $1.2 million in deferred underwriting commissions.

Simultaneously with the closing of the Initial Public Offering, we consummated the private placement (“Private Placement”) of 6,733,333 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) at a price of $1.50 per Private Placement Warrant to our Sponsor, generating gross proceeds of $10.1 million. In connection with the consummation of the sale of additional Units pursuant to the underwriters’ over-allotment option, on August 26, 2020, we sold 447,801 Private Placement Warrants to our Sponsor, generating additional gross proceeds of approximately $0.7 million.

16

Upon the closing of the Initial Public Offering and the Private Placement on August 20, 2020, $350.0 million ($10.00 per Unit) of the net proceeds of the sale of the Units in the Initial Public Offering and the Private Placement were placed in a trust account (“Trust Account”), located in the United States at J.P. Morgan Chase Bank, N.A. with Continental Stock Transfer & Trust Company acting as trustee, and invested only in U.S. “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the assets held in the Trust Account as described below. Upon closing of the sale of Units and Private Placement Warrants upon exercise of the over-allotment, on August 26, 2020, $34.3 million of the net proceeds of the sale of the Units and Private Placement Warrants were placed in the Trust Account.

If we are unable to complete a Business Combination within 24 months from the closing of the Initial Public Offering, or August 20, 2022, unless we provide the Public Stockholders with the opportunity to redeem their shares of Class A common stock in conjunction with any such amendment, we will (i) cease all operations except for the purposedevelopment changes), or should our underlying assumptions prove incorrect, actual outcomes may vary materially from those reflected in our forward-looking statements. Statements in this third-quarter 2021 Form 10-Q are made as 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, equalNovember 9, 2021, and Stem disclaims any intention or obligation 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 us to pay our franchise and income taxes (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), subject to applicable law, and (iii) as promptly as reasonably possible followingupdate publicly or revise 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.

Results of Operations

Our entire activity since inception through September 30, 2020 related to our formation, the preparation for the Initial Public Offering, and since the closing of the Initial Public Offering, the search for a prospective initial Business Combination. We have neither engaged in any operations nor generated any revenues to date. We will not generate any operating revenues until after completion of our initial Business Combination. We will generate non-operating income in the form of gain on investment (net), dividends and interest held in Trust Account. We expect to incur increased expensesstatements, whether as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses.

Fornew information, future events or otherwise.


You should read the three months ended September 30, 2020, we had net loss of approximately $374,000, which consisted of approximately $111,000 in general and administrative expenses, approximately $133,000 in general and administrative expenses for costs incurred with our Sponsor and approximately $149,000 of franchise tax expense, which was partially offset by approximately $19,000 gain on investment (net), dividends and interest held in Trust Account.

For the nine months ended September 30, 2020, we had net loss of approximately $377,000, which consisted of approximately $111,000 in general and administrative expenses, approximately $133,000 in general and administrative expenses for costs incurred with our Sponsor and approximately $151,000 of franchise tax expense, which was partially offset by approximately $19,000 gain on investment (net), dividends and interest held in Trust Account.

For the three months ended September 30, 2020, we had net loss of approximately $1,100, which consisted of approximately $1,100 in general and administrative expenses.

For the nine months ended September 30, 2020, we had net loss of approximately $10,000, which consisted of approximately $10,000 in general and administrative expenses and approximately $400 of franchise tax expense.

Liquidity and Capital Resources

As of September 30, 2020, we had approximately $1.8 million in our operating bank account and working capital of approximately $1.8 million. Our liquidity needs to date have been satisfied through a capital contribution of $25,000 from our Sponsor to purchase the Founder Shares, the loan of up to $300,000 under a note agreement with our Sponsor (the “Note”), and the net proceeds from the consummation of the Private Placement not held in the Trust Account. We fully repaid the Note on August 20, 2020. In addition, in order to finance transaction costs in connection with a Business Combination, our officers, directors and initial stockholders may, but are not obligated to, provide us working capital loans. To-date, there have been no borrowings under any working capital loans.

17

Based on the foregoing, management believes that we will have sufficient working capital and borrowing capacity from our Sponsor or an affiliate of our Sponsor, or our officers and directors to meet our needs through the earlier of the consummation of a Business Combination or one year from this filing. Over this time period, we will be using these funds for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.

We continue to evaluate the impact of the COVID-19 pandemic and have concluded that the specific impact is not readily determinable as of the date of the balance sheet. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Contractual Obligations

We do not have any long-term debt obligations, capital lease obligations, operating lease obligations, purchase obligations or long-term liabilities, other than an agreement to pay Administrative Services Agreement fees to our Sponsor that total $10,000 per month for office space, secretarial and administrative services provided to members of our management team.

Overview
Our mission is to build and operate the largest, digitally connected, intelligent energy storage network for our customers. In order to fulfill our mission, (i) we provide our customers, which include commercial and industrial (“C&I”) enterprises as well as independent power producers, renewable project developers, utilities and grid operators, with an energy storage system, sourced from leading, global battery original equipment manufacturers (“OEMs”), that we deliver through our partners, including solar project developers and engineering, procurement and construction firms and (ii) through our Athena artificial intelligence (“AI”) platform (“Athena”), we provide our customers with on-going software-enabled services to operate the energy storage systems for 10 to 20 years. In addition, in all the markets where we operate our customers’ systems, we have agreements to manage the energy storage systems using the Athena platform to participate in energy markets and to share the revenue from such market participation.
We operate in two key areas within the energy storage landscape: Behind-the-Meter (“BTM”) and Front-of-the-Meter (“FTM”). An energy system’s position in relation to a customer’s electric meter determines whether it is designated a BTM or FTM system. BTM systems provide power that can be used on-site without interacting with the electric grid and passing through an electric meter. Our BTM systems reduce C&I customer energy bills and help our customers facilitate the achievement of their corporate environmental, social, and corporate governance (“ESG”) objectives. FTM, grid-connected systems provide power to off-site locations and must pass through an electric meter prior to reaching an end-user. Our FTM systems decrease risk for project developers, lead asset professionals, independent power producers and investors by adapting to dynamic energy market conditions in connection with the deployment of electricity and improving the value of energy storage over the course of their FTM system’s lifetime.
Since our inception in 2009, we have engaged in developing and marketing Athena’s software enabled services, raising capital, and recruiting personnel. We have incurred net operating losses and negative cash flows from operations each year since our inception. We have financed our operations primarily through the issuance of convertible preferred stock, debt financing, and cash flows from customers.
Our total revenue grew from $9.2 million for the three months ended September 30, 2020 to $39.8 million for the three months ended September 30, 2021. For the three months ended September 30, 2021 and 2020, we earned net income of $115.6 million and incurred net losses of $18.8 million, respectively. Our total revenue grew from $17.7 million for the nine months ended September 30, 2020 to $74.6 million for the nine months ended September 30, 2021. For the nine months ended September 30, 2021 and 2020, we incurred net losses of $67.2 million and $55.2 million, respectively. As of September 30, 2021, we had an accumulated deficit of $475.0 million.

We expect that our sales and marketing, research and development, regulatory and other expenses will continue to increase as we expand our marketing efforts to increase sales of our solutions, expand existing relationships with our customers, and obtain regulatory clearances or approvals for future product enhancements. In addition, we expect our general and administrative costs and expenses to increase due to the additional costs associated with scaling our business operations as well as being a public company, including legal, accounting, insurance, exchange listing and SEC compliance, investor relations and other costs and expenses.
Some Key Factors, Trends and Risks Affecting our Business
We believe that our performance and future success depend on several factors that present significant opportunities for us but also pose risks and challenges, including but not limited to:
Decline in Lithium-Ion Battery Costs
Our revenue growth is directly tied to the continued adoption of energy storage systems by our customers. The cost of lithium ion energy storage hardware has declined significantly in the last decade and has resulted in a large addressable market today. The market for energy storage is rapidly evolving, and while we believe costs will continue to decline, there is no guarantee. If costs do not continue to decline, or do not decline as quickly as we anticipate, this could adversely affect our ability to increase our revenue and grow our business.
Increase in Deployment of Renewables
Deployment of intermittent resources has accelerated over the last decade, and today, wind and solar have become a low cost fuel source. We expect the cost of generating renewable energy to continue to decline and deployments of energy storage systems to increase. As renewable energy sources of energy production are expected to represent a larger proportion of energy generation, grid instability rises due to their intermittency, which can be addressed by energy storage solutions.
27


Competition
We are currently a market leader in terms of capacity of energy storage under management. We intend to expand our market share over time by leveraging the network effect of Athena’s AI infrastructure. Existing competitors may expand their product offerings and sales strategies, and new competitors may enter the market. Furthermore, our competitors include other types of software providers and some hardware manufacturers that offer software solutions. If our market share declines due to increased competition, our revenue and ability to generate profits in the future may be adversely affected.
Government Regulation and Compliance
Although we are not regulated as a utility, the market for our product and services is heavily influenced by federal, state, and local government statutes and regulations concerning electricity. These statutes and regulations affect electricity pricing, net metering, incentives, taxation, competition with utilities, and the interconnection of customer-owned electricity generation. In the United States and internationally, governments continuously modify these statutes and regulations and acting through state utility or public service commissions, regularly change and adopt different rates for commercial customers. These changes can positively or negatively affect our ability to deliver cost savings to customers.
Impact of COVID-19

The ongoing COVID-19 pandemic has resulted and may continue to result in widespread adverse effects on the global and the U.S. economy. Ongoing government and business responses to COVID-19, along with the COVID-19 Delta variant and resurgence of related disruptions, could have a continued material adverse impact on economic and market conditions and trigger a period of continued global and U.S. economic slowdown.

Our industry is currently facing shortages and shipping delays affecting the supply of inverters, enclosures, battery modules and associated component parts for inverters and battery energy storage systems available for purchase. These shortages and delays can be attributed in part to the COVID-19 pandemic and resulting government action. While a majority of our suppliers have secured sufficient supply to permit them to continue delivery and installations through the end of 2021, if these shortages and delays persist into 2022, they could adversely affect the timing of when battery energy storage systems can be delivered and installed, and when (or if) we can begin to generate revenue from those systems.We cannot predict the full effects the COVID-19 pandemic will have on our business, cash flows, liquidity, financial statements,condition and results of operations at this time due to numerous uncertainties. We will continue to monitor developments affecting our workforce, our suppliers, our customers and our business operations generally, and will take actions we determine are necessary in order to mitigate these impacts as much as possible.


Non-GAAP Financial Measures
In addition to our results determined in accordance with GAAP, we use Adjusted EBITDA and non-GAAP gross margin, which have beenare non-GAAP financial measures, for financial and operational decision making and as a means to evaluate our operating performance and future prospects, develop internal budgets and financial goals, and to facilitate period-to-period comparisons. Our management believes that these non-GAAP financial measures provide meaningful supplemental information regarding our performance and liquidity by excluding certain expenses and expenditures that may not be indicative of our operating performance, such as stock-based compensation and other non-cash charges, as well as discrete cash charges that are infrequent in nature. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, and analyzing future periods. These non-GAAP financial measures also facilitate management’s internal comparisons to our historical performance and liquidity as well as comparisons to our competitors’ operating results. We believe these non-GAAP financial measures are useful to investors both because they (1)allow for greater transparency with respect to key metrics used by management in its financial and operational decision making and (2)are used by our institutional investors and the analyst community to help them analyze the health of our business. Adjusted EBITDA and non-GAAP gross margin should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP.
Non-GAAP gross margin

We define non-GAAP gross margin as gross margin excluding amortization of capitalized software, impairments related to decommissioning of end-of-life systems, and certain operating expenses including communication and cloud services expenditures reclassified to cost of revenue.

Adjusted EBITDA

As discussed above, we believe that Adjusted EBITDA is useful for investors to use in comparing our financial performance with the performance of other companies. Nonetheless, the expenses and other items that we exclude in our calculation of Adjusted EBITDA may differ from the expenses and other items, if any, that other companies may exclude when calculating Adjusted EBITDA.

We calculate Adjusted EBITDA as net income (loss) before net interest expense, income tax provision and depreciation and amortization, including amortization of internally developed software, further adjusted to exclude stock-based compensation and other income and expense items, including the change in fair value of warrants and embedded derivatives, vesting of warrants and loss on extinguishment of debt.

Pipeline

Pipeline represents the total value (excluding market participation revenue) of uncontracted, potential hardware and software contracts that are currently being pursued by Stem direct salesforce and channel partners with developers and independent power producers seeking energy optimization services and transfer of energy storage systems that have a reasonable likelihood of execution within 12 months of the end of the relevant period based on project timelines published by such developers and independent power producers. We cannot guarantee that our pipeline will result in meaningful revenue or profitability.

Bookings
Due to the long-term nature of our contracts, bookings are a key metric that allows us to understand and evaluate the growth of our Company and our estimated future revenue related to customer contracts for our energy optimization services and transfer of energy storage systems. Bookings represents the accumulated value at a point in time of contracts that have been executed under both our host customer and partnership sales models.

For host customer sales, bookings represent the expected consideration from energy optimization services contracts, including estimated incentive payments that are earned by the host customer from utility companies in relation to the services provided by us and assigned by the host customer to us. For host customer sales, there are no differences between bookings and remaining performance obligations at any point in time.

For partnership sales, bookings are the sum of the expected consideration to be received from the transfer of hardware and energy optimization services (excluding any potential revenues from market participation). For partnership sales, even though we have secured an executed contract with estimated timing of project delivery and installation from the customer, we do not consider it a contract in accordance with ASC 606 or a remaining performance obligation until the customer has placed a binding purchase order. A signed customer contract is considered a booking as this indicates the customer has agreed to place a
30


purchase order in the foreseeable future, which typically occurs within three (3) months of contract execution. However, executed customer contracts, without binding purchase orders, are cancellable without penalty by either party.

For partnership sales, once a purchase order has been executed, the booking is considered to be a contract in accordance with ASC 606, and therefore, gives rise to a remaining performance obligation as we have an obligation to transfer hardware and energy optimization services in our partnership agreements. We also have the contractual right to receive consideration for our performance obligations.

The accounting principlespolicy and timing of revenue recognition for host customer contracts and partnership arrangements that qualify as contracts with customers under ASC 606, are described within Note 3- Revenue, of the Notes to the audited consolidated financial statements as of December 31, 2020.

Components of Our Results of Operations
Revenue
We generate service revenue and hardware revenue. Service revenue is generated through arrangements with host customers to provide energy optimization services using our proprietary cloud-based software platform coupled with a dedicated energy storage system owned and controlled by us throughout the term of the contract. Fees charged to customers for energy optimization services generally acceptedconsist of recurring fixed monthly payments throughout the term of the contract and in some arrangements, an installation and/or upfront fee component. We may also receive incentives from utility companies in relation to the sale of our services.

We generate hardware revenue through partnership arrangements consisting of promises to sell an energy storage system to a solar plus storage project developers. Performance obligations are satisfied when the energy storage system along with all ancillary hardware components are delivered. The milestone payments received before the delivery of hardware is treated as deferred revenue. We separately generate services revenue through partnership arrangements by providing energy optimization services after the developer completes the installation of the project.
Cost of Revenue
Cost of hardware revenue includes the cost of the hardware, which generally includes the cost of the hardware purchased from a manufacturer, shipping, delivery, and other costs required to fulfill our obligation to deliver the energy storage system to the customer location. Cost of revenue may also include any impairment of energy storage systems held in our inventory for sale to our customer. Cost of hardware revenue related to the sale of energy storage systems is recognized when the delivery of the product is completed.

Cost of service revenue includes depreciation of the cost of energy storage systems we own under long-term customer contracts, which includes capitalized fulfillment costs, such as installation services, permitting and other related costs. Cost of revenue may also include any impairment of inventory and energy storage systems, along with system maintenance costs associated with the ongoing services provided to customers. Costs of revenue are recognized as energy optimization and other supporting services are provided to our customers throughout the term of the contract.
Gross Margin
Our gross margin fluctuates significantly from quarter to quarter. Gross margin, calculated as revenue less costs of revenue, has been, and will continue to be, affected by various factors, including fluctuations in the amount and mix of revenue and the amount and timing of investments to expand our customer base. We hope to increase both our gross margin in absolute dollars and as a percentage of revenue through enhanced operational efficiency and economies of scale.
Operating Expenses
Sales and Marketing
Sales and marketing expense consists of payroll and other related personnel costs, including salaries, stock-based compensation, employee benefits, and travel for our sales and marketing personnel. In addition, sales and marketing expense includes trade show costs, amortization of intangibles and others expenses. We expect to our selling and marketing expense to increase in future periods to support the overall growth in our business.

31


Research and development
Research and development expense consists primarily of payroll and other related personnel costs for engineers and third parties engaged in the design and development of products, third-party software and technologies, including salaries, bonus and stock-based compensation expense, project material costs, services and depreciation. We expect research and development expense to increase in future periods to support our growth, including continuing to invest in optimization, accuracy and reliability of our platform and other technology improvements to support and drive efficiency in our operations. These expenses may vary from period to period as a percentage of revenue, depending primarily upon when we choose to make more significant investments.
General and Administrative Expense
General and administrative expense consists of payroll and other related personnel costs, including salaries, stock-based compensation, employee benefits and expenses for executive management, legal, finance and other costs. In addition, general and administrative expense includes fees for professional services and occupancy costs. We expect our general and administrative expense to increase in future periods as we scale up headcount with 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 activities, and other administrative and professional services.
Other Income (Expense), Net
Interest Expense
Interest expense consists primarily of interest on our outstanding borrowings under our outstanding notes payable, convertible promissory notes, and financing obligations and accretion on our asset retirement obligations.
Loss on Extinguishment of Debt
Loss on extinguishment of debt consists of penalties incurred in relation to the prepayment of our outstanding borrowings under our outstanding notes payable and the write-off of any unamortized debt issuance costs associated with such notes.
Change in Fair Value of Warrants and Embedded Derivatives
Change in fair value of warrants and embedded derivatives is related to the revaluation of our outstanding convertible preferred stock warrant liabilities and embedded derivatives related to the redemption features associated with our convertible notes at each reporting date.
Other Expenses, Net
Other expenses, net consists primarily of income from equity investments and foreign exchange gains or losses.

Other Income (Expense), Net
Interest Expense
Interest expense decreased by $1.6 million, or 37%, for the three months ended September 30, 2021 compared to the three months ended September 30, 2020. The decrease was primarily driven by the repayment of loans and the conversion of convertible notes in relation to the Merger. The decrease in interest expense was partially offset by an increase of $0.7 million in interest expense in connection with the financing obligation, and an increase of $0.3 million in amortization of premium on debt securities.
Change in Fair Value of Warrants and Embedded Derivative
The change in fair value of warrants and embedded derivative reflected $137.0 million gain in the three months ended September 30, 2021, compared to $2.1 million loss the three months ended September 30, 2020.

The $137.0 million gain in the three months ended September 30, 2021 resulted from the extinguishment of the warrant liability in connection with the exercise and redemption of the Public Warrants. The gain of $137.0 million encompasses a $134.9 million revaluation gain from the decrease in the fair value of the Public Warrants, and a $2.1 million gain on the redemption of unexercised Public Warrants on the Redemption Date.

The $2.1 million expense in the three months ended September 30, 2020 resulted from a revaluation loss of the Series A, D and D’ warrants and embedded derivative.
Other Expenses, Net
Other expenses, net increased by $0.2 million, or 121%, for the three months ended September 30, 2021 compared to the three months ended September 30, 2020. The net increase was primarily driven by foreign exchange losses realized in the period related to operations in Canada.

Research and development expense increased by $3.4 million, or 28%, for the nine months ended September 30, 2021, as compared to the nine months ended September 30, 2020. The increase was primarily due to an increase of $5.3 million in personnel related expenses as a result of increased headcount, an increase of $0.9 million in stock-based compensation expense primarily due to grants of stock options and RSUs to employees, and an increase of $0.2 million in office related expenses. The increase was partially offset by a decrease of $2.5 million in third-party software and technologies related expenses, and a decrease of $0.5 million in professional services.
General and Administrative
General and administrative expense increased by $20.7 million, or 258%, for the nine months ended September 30, 2021, as compared to the nine months ended September 30, 2020. The increase was primarily driven by an increase of $12.0 million in professional and legal services including $9.2 million for warrants issued for services in April 2021, an increase of $4.9 million in stock-based compensation expense, an increase of $2.5 million in insurance related expenses, and an increase of $1.4 million in personnel related expenses due to higher headcount. The increase was partially offset by a decrease of $0.1 million in miscellaneous expenses.

Other Income (Expense), Net
Interest Expense
Interest expense decreased by $1.0 million, or 7%, for the nine months ended September 30, 2021, as compared to the nine months ended September 30, 2020. The increase was primarily driven by the repayment of notes payable during 2021.
Loss on Extinguishment of Debt
Loss on extinguishment of debt increased by $5.1 million for the nine months ended September 30, 2021, as compared to the nine months ended September 30, 2020. The increase was driven by payment of a $4.0 million penalty on debt extinguishment and the write-off of $1.1 million of unamortized debt issuance costs upon the conversion of our Series D convertible notes in relation to the Merger.
Change in Fair Value of Warrants and Embedded Derivative
The change in fair value of warrants and embedded derivative reflected a $3.4 million income for the nine months ended September 30, 2021, compared to $3.0 million expense for the nine months ended September 30, 2020.

The income of $3.4 million in the nine months ended September 30, 2021 primarily resulted from a decrease in the fair value of the Public Warrants, which was recorded as a gain in revaluation of the warrant liability, in connection with the exercise and redemption of the Public Warrants during the third quarter of 2021. The income of $3.4 million was partially offset by an increase in the fair value of warrant liabilities during the first and second quarter of 2021.

The expense of$3.0 million in the nine months ended September 30, 2020 primarily resulted from a loss on revaluation of Series A, D and D’ warrants and embedded derivative.
Other Expenses, Net
Other expenses, net decreased by $1.8 million, or 113%, for the nine months ended September 30, 2021, as compared to the nine months ended September 30, 2020. The net decrease was primarily driven by $1.2 million in legal settlement and late fees incurred in the nine months ended September 30, 2021 and a $0.4 million decrease in foreign exchange losses realized in the period related to operations in Canada.
Liquidity and Capital Resources
36


Sources of liquidity
Liquidity describes the ability of a company to generate sufficient cash flows to meet the cash requirements of its business operations, including working capital needs, debt service, acquisitions, contractual obligations and other commitments. We assess liquidity in terms of our cash flows from operations and their sufficiency to fund our operating and investing activities. To meet our payment service obligations we must have sufficient liquid assets and be able to move funds on a timely basis.

As of September 30, 2021, our principal source of liquidity is cash generated from financing activities. Cash generated from financing activities through September 30, 2021 primarily includes proceeds from the Merger that provided us with approximately $550.3 million, net of fees and expenses, sales of convertible preferred stock, proceeds from convertible notes, proceeds from our various borrowings, and the exercise of Public Warrants, which increased our cash balance by $145.3 million. In connection with the Merger, the convertible notes and related accrued interest converted to equity and we paid in full all other outstanding debt except the 2021 Credit Agreement described below. We believe that our cash position is sufficient to meet our capital and liquidity requirements for at least the next 12 months therefore, there is not substantial doubt about our ability to continue as a going concern.

Our business prospects are subject to risks, expenses and uncertainties frequently encountered by companies in the early stages of commercial operations. The attainment of profitable operations is dependent upon future events, including obtaining adequate financing to complete our development activities, obtaining adequate supplier relationships, building our customer base, successfully executing our business and marketing strategy and hiring appropriate personnel. Failure to generate sufficient revenues, achieve planned gross margins and operating profitability, control operating costs, or secure additional funding may require us to modify, delay, or abandon some of our planned future expansion or development, or to otherwise enact operating cost reductions available to management, which could have a material adverse effect on our business, operating results, financial condition and ability to achieve our intended business objectives.

In the future, we may be required to obtain additional equity or debt financing in order to support our continued capital expenditures and operations. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us or at all. If we are unable to raise additional capital or generate cash flows necessary to expand our operations and invest in new technologies, this could reduce our ability to compete successfully and harm our business, growth and results of operations.

Our long-term liquidity requirements primarily are linked to the continued extension of the Athena platform and the use of our balance sheet to improve the terms and conditions associated with the purchase of energy storage systems from our hardware vendors. While we have plans to potentially expand our geographical footprint beyond our current partnerships and enter into joint ventures, those are not required initiatives to achieve our plan.

In addition to the foregoing, based on our current assessment, we do not expect any material adverse effect on our long-term liquidity due to the COVID-19 pandemic or government responses thereto. However, we will continue to assess these effects to our operations. The extent to which the COVID-19 pandemic and government and business responses thereto will affect our business and operations will continue to depend on future developments that are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the pandemic, any restrictions on the ability of hospitals and trial sites to conduct trials that are not designed to address the COVID-19 pandemic and the perceived effectiveness of actions taken in the United States and other countries to contain and treat the disease. While the potential economic impact brought by COVID-19 and government and business responses may be difficult to assess or predict, a widespread pandemic and government and business responses could result in significant disruption of America. The preparationglobal financial markets, reducing our ability to access capital in the future. In addition, a recession or long-term market correction resulting from the spread of COVID-19 or government and business responses could materially affect our business and the value of our common stock.
Financing Obligations

We have entered into arrangements wherein we finance the cost of energy storage systems via special purpose entities (“SPE”) we establish with outside investors. These SPEs are not consolidated into our financial statements, but are accounted for as equity method investments. Through the SPEs, the investors provide us upfront payments. Under these arrangements, the payment by the SPE to us is accounted for as a borrowing by recording the proceeds received as a financing obligation. The financing obligation is repaid with the future customer payments and incentives received. A portion of the amounts paid to the SPE is allocated to interest expense using the effective interest rate method.

37


Furthermore, we continue to account for the revenues from customer arrangements and incentives and all associated costs despite such systems being legally sold to the SPEs due to our significant continuing involvement in the operations of the energy storage systems.

The total financing obligation as of September 30, 2021 was $89.7 million, of which $14.3 million was classified as a current liability.
Notes Payable
Revolving Loan Due to SPE Member

In April 2017, we entered into a revolving loan agreement with an affiliate of a member of certain SPEs in which we have an ownership interest. The purpose of this revolving loan agreement is to finance our purchase of hardware for its various energy storage system projects. We have amended the loan from time to time as our business has grown, and as of the beginning of 2020, the agreement had a total revolving loan capacity of $45.0 million that bore fixed interest at 10% with a maturity date of June 2020.

In May 2020, concurrent with the 2020 Credit Agreement discussed below, we amended the facility to reduce the loan capacity to $35.0 million and extend the maturity date to May 2021. The amendment increased the fixed interest rate for any borrowings outstanding more than nine (9) months to 14% thereafter.

Additionally, under the original terms of the revolving loan agreement, we were able to finance 100% of the value of the hardware purchased up to the total loan capacity. The amendment reduced the advance rate to 85%, with an additional reduction to 70% in August 2020. We had $9.6 million outstanding under this revolving loan agreement as of March 31, 2021. In April 2021, we repaid the remaining outstanding balance in full.
Term Loan Due to SPE Member

In December 2018, we entered into a term loan in the amount of $13.3 million with an affiliate of a member of certain SPEs in which we have an ownership interest. As of the beginning of 2020, this term loan bore fixed interest of 12.5% on the outstanding principal balance with a final balloon payment of $3.0 million due at the maturity date of June 30, 2020. In May 2020, we repaid the remaining outstanding balance of $5.9 million with the proceeds received through the 2020 Credit Agreement discussed below.
Term Loan Due to Former Non-Controlling Interest Holder

In June 2018, we acquired the outstanding member interests of an entity we controlled for $8.1 million. We financed this acquisition by entering into a term loan agreement with the noncontrolling member bearing fixed interest of 18% (4.5% quarterly) on the outstanding principal balance. This loan requires fixed quarterly payments throughout the term of the loan, which will be paid in full by April 1, 2026. In May 2020, we amended the term loan and, using the proceeds from the 2020 Credit Agreement discussed below, prepaid $1.5 million of principal and interest on the note, of which $1.0 million was towards the outstanding principal balance, thereby reducing the fixed quarterly payment due to the lender. In relation to this amendment, we were required to issue warrants for 400,000 shares of common stock resulting in a discount to the term loan of $0.2 million. Such debt discount is amortized to earnings through interest expense over the expected life of the debt. In April 2021, we repaid the remaining outstanding balance in full.
2020 Credit Agreement

In May 2020, we entered into a credit agreement (“2020 Credit Agreement”) with a new lender that provided us with proceeds of $25.0 million that increased our access to make estimatesworking capital. The 2020 Credit Agreement has a maturity date of the earlier of (1) May 14, 2021, (2) the maturity date of the revolving loan agreement, or (3) the maturity date of the convertible promissory notes discussed below. The loan bears interest of 12% per annum, of which 8% is paid in cash and judgments4% is added back to principal of the loan balance every quarter. We used a portion of the proceeds towards payments associated with existing debt as previously discussed. In April 2021, we repaid the remaining outstanding balance in full.
2021 Credit Agreement

In January 2021, we entered into a non-recourse credit agreement to provide a total of $2.7 million towards the financing of certain energy storage systems that affectwe own and operate. The credit agreement has a stated interest of 5.45% and a maturity date
38


of June 2031. We received an advance under the reported amountscredit agreement of $1.8 million in January 2021. The repayment of advances received under this credit agreement is determined by the lender based on the proceeds generated by us through the operation of the underlying energy storage systems. We have $1.9 million of outstanding borrowings under this credit agreement as of September 30, 2021.

Net increase (decrease) in cash and cash equivalents$398,247 $(4,946)
Operating Activities
During the nine months ended September 30, 2021, net cash used in operating activities was $69.0 million, primarily resulting from our operating loss of $67.2 million, adjusted for non-cash charges of $40.4 million and net cash outflow of $42.3 million from changes in operating assets liabilities, revenues and liabilities. Non-cash charges primarily consisted of depreciation and amortization of $15.6 million, non-cash interest expense of $8.1 million, which includes interest expenses associated with debt issuance costs, stock-based compensation expense of $8.0 million, change in the fair value of warrant liability and the disclosureembedded derivative of contingent$3.4 million, impairment of energy storage systems of $2.2 million, issuance of warrants for services of $9.2 million, noncash lease expense of $0.3 million, accretion expense of $0.2 million, and net amortization of premium on investments of $0.3 million . The net cash outflow from changes in operating assets and liabilities was primarily driven by an increase in our financial statements. Onaccounts receivable of $21.4 million, an ongoing basis, we evaluate our estimatesincrease in other assets of $18.1 million, a decrease in deferred revenue of $3.5 million, an increase in inventory of $3.4 million, and judgments, including those related to fair valuean increase in contract origination costs of financial instruments$1.9 million, partially offset by an increase in accounts payable and accrued expenses. We base our estimates on historical experience, known trends and events and various other factors that we believe to be reasonable underexpenses of $6.2 million.
During the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. The Company has identified the following as its critical accounting policies:

Class A Common Stock Subject to Possible Redemption

Class A common stock subject to mandatory redemption (if any) is classified as a liability instrument and measured at fair value. Conditionally redeemable Class A common stock (including Class A 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, Class A common stock is classified as stockholders’ equity. Our outstanding Class A common stock features certain redemption rights that are considered to be outside of our control and subject to the occurrence of uncertain future events. Accordingly, at September 30, 2020, 36,683,412 shares of Class A common stock subject to possible redemption is presented as temporary equity, outside of the stockholders’ equity section of the unaudited condensed balance sheet.

Net Income (Loss) Per Common Share

Net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common stock outstanding during the periods. We have not considered the effect of the warrants sold in the Initial Public Offering and the Private Placement to purchase up to an aggregate of 19,967,302 shares of our Class A common stock in the calculation of the diluted income per share, since their inclusion would be anti-dilutive under the treasury stock method.

18

The unaudited condensed statements of operations include a presentation of income (loss) per share for common stock subject to redemption in a manner similar to the two-class method of income (loss) per share. Net income per common share, basic and diluted for Class A common stock is calculated by dividing the gain on investment (net), dividends and interest held in Trust Account of approximately $19,000 for the three and nine months ended September 30, 2020, net cash used in operating activities was $17.9 million, primarily resulting from our operating loss of applicable taxes available to be withdrawn$55.2 million, adjusted by non-cash charges of $25.9 million and net cash inflow of $11.4 million from changes in operating assets and liabilities. Non-cash charges primarily consisted of depreciation and amortization of $13.8 million, non-cash interest expense of $7.1 million, which includes interest expenses associated with debt issuance costs, stock-based compensation expense of $1.4 million, and change in the Trust Accountfair value of approximately $19,000warrant liability and embedded derivative of $3.0 million. The net cash inflow from changes in operating assets and liabilities was primarily driven by an increase in deferred revenue of $32.3 million, an increase in accounts payable and accrued expenses of $2.8 million, and an decrease in deferred costs with suppliers of $2.8 million, partially offset by an increase in inventory of $17.6 million, an increase in accounts receivable of $6.0 million, an increase in contract origination costs of $2.1 million, and an decrease in lease liabilities of $0.5 million.

Investing Activities
During the nine months ended September 30, 2021, net cash used for investing activities was $182.1 million, primarily consisting of $171.1 million in purchase of available-for-sale investments, $6.2 million in purchase of energy systems and $4.3 million in capital expenditures on internally-developed software.
During the three and nine months ended September 30, 2020, resultingnet cash used for investing activities was $7.7 million, consisting of $4.1 million in net incomepurchase of $0 forenergy systems and $3.6 million in capital expenditures on internally-developed software.

Evaluation of CONTROLS AND PROCEDURES


1. Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial and accounting officer, we conducted an evaluation of the effectiveness of our

We maintain disclosure controls and procedures as(Disclosure Controls) within the meaning of the end of the fiscal quarter ended September 30, 2020, as such term is defined in Rules 13a-15(e) and 15d-15(e) underof the Securities Exchange Act. Based on this evaluation, our chief executive officer and chief financial officer have concluded that during the period covered by this report, our disclosure controls and procedures were effective.

Act of 1934, as amended, (the “Exchange Act”). Our Disclosure controls and proceduresControls are designed to ensure that information required to be disclosed by us in ourthe reports we file or submit under the Exchange Act, reportssuch as this Quarterly Report on Form 10-Q, is recorded, processed, summarized and reported within the time periods specified in the SEC’sSecurities and Exchange Commission’s rules and forms, andforms. Our Disclosure Controls are also designed to ensure that such information is accumulated and communicated to our management, including our principal executive officerChief Executive Officer and principal financial officer or persons performing similar functions,Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

In designing and evaluating our Disclosure Controls, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable, and not absolute, assurance of achieving the desired control objectives, and management necessarily applied its judgment in evaluating and implementing possible controls and procedures.


Based on management’s evaluation (under the supervision and with the participation of our Chief Executive Officer and our Chief Financial Officer), as of the end of the period covered by this report, of the effectiveness of the design and operation of our Disclosure Controls, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this report, our Disclosure Controls were not effective due to a material weakness in the Company’s internal control over financial reporting as disclosed below.

2. Material Weaknesses in Internal Control Over Financial Reporting
40



During the course of preparing our financial statements as of and for the year ended December 31, 2020, management identified certain deficiencies in our internal controls over financial reporting that management believes to be a material weaknesses. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that a reasonable possibility exists that a material misstatement of our annual or interim financial statements would not be prevented or detected on a timely basis.

Specifically, the material weaknesses identified relate to (i) ineffective internal controls over accounting for complex and significant transactions, (ii) accounting for energy storage systems, deferred cost of goods sold and inventory, (iii) ineffective internal controls over review of the Company’s unaudited condensed consolidated financial statements and related disclosures, (iv) a lack of formality in our internal control activities, especially related to management review-type controls, (v) ineffective internal controls over the review of certain revenue recognition calculations, and (vi) ineffective internal controls over the review of internal-use capitalized software calculations. With respect to accounting for complex and significant transactions, deficiencies exist in our process for ensuring the completeness of information utilized in various technical accounting analyses and, in certain instances, the proper application of the relevant accounting literature, including the determination of the appropriate valuation methodology. These deficiencies could result in material adjustments for certain transactions, including interest capitalization and accounting for convertible notes, and accounting and valuation of embedded derivatives and warrant liabilities. With respect to energy storage systems, inventory and deferred cost of goods sold, we did not properly track inflows and outflows, including the valuation of energy storage systems, due in part to the systems that the Company used to track and value energy storage systems and inventory. With respect to a lack of formality in our control activities, we did not sufficiently establish formal policies and procedures to design effective controls, establish responsibilities to execute these policies and procedures and hold individuals accountable for performance of these responsibilities, including over review over revenue recognition and internal-use capitalized software calculations. We had multiple control deficiencies aggregating to a material weakness over ineffective control activities.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements or prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions, and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

3. Plan to Remediate Material Weaknesses in Internal Control Over Financial Reporting

The Company, with oversight of the Audit Committee of the Board, continues to devote significant time, attention and resources to remediating the above material weaknesses in its internal control over financing reporting. As of September 30, 2021, the Company had initiated the following steps intended to remediate the material weakness described above and strengthen its internal control over financial reporting:

Develop and deliver internal control training to management and finance/accounting personnel, focusing on a review of management’s and individual roles and responsibilities related to internal control over financial reporting.
Hire, train and develop experienced accounting executives and personnel with a level of public accounting knowledge and experience in the application of US GAAP commensurate with our financial reporting requirements and the complexity of our operations and transactions.
Establish and implement policies and practices to attract, develop and retain competent public accounting personnel.
Engage a qualified third party Sarbanes-Oxley (“SOX”) compliance firm to assist the Company in bolstering and implementing our SOX compliance program, with a focus on documenting processes and controls, identifying and addressing control gaps, formalizing the internal control activities and strengthening the overall quality of documentation that evidences control activities.
Perform a financial statement risk assessment and scoping exercise to identify and assess the risks of material misstatements in our financial statements to better ensure that the appropriate effort and resources are dedicated to addressing risks of material misstatements.
Establish a disclosure committee comprised of our CEO, CFO, Chief Legal Officer and senior finance/accounting personnel to, among other things, review and, as necessary, help revise the Company’s controls and other procedures
41


to ensure that information required by the Company to be disclosed is recorded, processed, summarized and reported accurately and on a timely basis.
Implement a Section 302 sub-certification program to reinforce the Company’s culture of compliance.
Implement processes to improve monitoring activities involving the review and supervision of our accounting operations, including increased and enhanced balance sheet reviews to allow more focus on quality account reconciliations and enhanced monitoring of our internal control over financial reporting.

We plan to continue to devote significant time and attention to remediate the above material weaknesses as soon as reasonably practicable. As we continue to evaluate our controls, we will make the necessary changes to improve our demonstration of commitment to attract, develop and retain competent individuals. We believe these actions will be sufficient to remediate the identified material weaknesses and strengthen our internal control over financial reporting; however, there can be no guarantee that such remediation will be sufficient. We will continue to evaluate the effectiveness of our controls and will make any further changes management determines appropriate.
