EXPLANATORY NOTE

We are filing this Post-Effective Amendment No. 2 to the Registration Statement on Form S-1 (File No. 333-264910) (the “Registration Statement”), as originally declared effective by the Securities and Exchange Commission (“SEC”) on June 30, 2022, to convert the Registration Statement to a Registration Statement on Form S-3. The information included in this filing amends the Registration Statement and the prospectus contained therein. No additional securities are being registered under this Post-Effective Amendment No. 2, and we have updated the Registration Statement to eliminate securities sold and transferred under the Registration Statement before the date of this amendment. All applicable registration fees were paid at the time of the original filing of the Registration Statement on May 13, 2022.

The information in this preliminary prospectus is not complete and may be changed. These securities may not be issued until the registration statement filed with the U.S. Securities and Exchange Commission is effective. This preliminary prospectus is not an offer to sell these securities and does not constitute the solicitation of an offer to buy these securities in any jurisdiction where the offer or sale is not permitted.

SUBJECT TO COMPLETION, DATED June 1, 2023

PRELIMINARY PROSPECTUS

204,063,030 Shares of Class A Common Stock

8,900,000 Warrants to Purchase Shares of Class A Common Stock

NUSCALE POWER CORPORATION

This prospectus relates to (1) the issuance by us of up to 154,720,015 shares of Class A Common Stock, par value $0.0001 per share (“Class A Common Stock”), of NuScale Power Corporation, a Delaware corporation (“NuScale Corp,” “we,” “our” or “us”), upon exchange (on a one-for-one basis, subject to adjustment) of Class B Units of NuScale Power, LLC, an Oregon limited liability company (“NuScale LLC”) (which Class B Units were originally purchased at various times since 2007 for ascribed prices per unit ranging from approximately $0.00 (for certain incentive awards) to $7.76 per unit, and which, together with Class B Units of NuScale LLC previously exchanged for Class A Common Stock, collectively had a weighted average ascribed purchase price of $4.74 per unit immediately after the Merger (defined below)) and cancellation of a corresponding number of shares of Class B Common Stock, par value $0.0001 per share, of NuScale Corp, and the resale of 171,755,372 shares of Class A Common Stock issued or issuable upon such exchange, the resale of which might otherwise be limited by the resale restrictions imposed on “control securities” under Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”); (2) the issuance by us of up to 9,558,701 shares of Class A Common Stock upon the exercise of the redeemable warrants issued in the IPO and converted in the Merger (defined below) into warrants to purchase Class A common (“Public Warrants”); (3) the issuance by us of up to 8,900,000 shares of Class A Common Stock upon the exercise of warrants to purchase Spring Valley Class A ordinary shares that were issued in a private placement concurrently with the IPO and converted in the Merger (defined below) into warrants to purchase Class A Common Stock (“Private Placement Warrants”) and the resale of such shares; and (4) the resale from time to time by the selling securityholders named in this prospectus or their permitted transferees of up to: 8,900,000 Private Placement Warrants, which were originally purchased for $1.00 per warrant; 22,137,482 shares of Class A Common Stock, which were originally purchased for approximately $10.00 per share by investors (“PIPE Investors”) immediately prior to the consummation of the Merger (defined below); and 120,000 shares of Class A Common Stock held by former directors of Spring Valley Acquisition Corp (“Spring Valley Founders”), which were originally purchased for approximately $0.003 per share.

On May 2, 2022 (the “Closing Date”), Spring Valley Acquisition Corp., formerly a blank check company incorporated as a Cayman Islands exempted company (“Spring Valley”), completed the previously announced transactions pursuant to the Agreement and Plan of Merger dated December 13, 2021 (as amended) between Spring Valley, Spring Valley Merger Sub, LLC, an Oregon limited liability company (“Merger Sub”) and NuScale LLC, including: (a) the domestication of Spring Valley as a Delaware corporation (and the change of its name to “NuScale Power Corporation”); and (b) the merger (the “Merger”) of Merger Sub with and into NuScale LLC, with NuScale LLC as the surviving business entity in the Merger, through which the combined company was reorganized in an “UP-C” structure, with NuScale Corp now serving as the sole manager of NuScale LLC. Immediately after the Merger, NuScale LLC was owned in part, indirectly through NuScale Corp, by former public and private shareholders of Spring Valley, and in part directly by continuing equity owners of NuScale LLC (the “Legacy NuScale Equityholders”).

After the domestication and immediately before completion of the Merger, Spring Valley issued to the PIPE Investors, in private placements, 23,700,002 shares of Class A Common Stock at approximately $10.00 per share, for an aggregate purchase price of $235,000,000.

In connection with the special meeting at which shareholders approved the Merger, holders of 8,599,631 shares of Class A Common Stock, or 37.5% of the shares with redemption rights, exercised their right to redeem their shares for cash at a redemption price of approximately $10.10 per share, for an aggregate redemption amount of $86.9 million. The shares of Class A Common Stock being offered for resale pursuant to this prospectus by the selling securityholders represent approximately 73.8% of shares outstanding on a fully diluted basis as of May 26, 2023, assuming the exercise of all outstanding options to purchase Class A Common Stock. The sale of shares by the selling securityholders, or the perception in the market that the selling securityholders intend to sell a large number of shares, could increase the volatility of the market price of Class A Common Stock or result in a significant decline in the public trading price of Class A Common Stock. Even if our trading price is significantly below $10.00, the offering price for the Spring Valley Units (composed of one Spring Valley Class A ordinary share and one half of a Spring Valley Public Warrant) offered in our initial public offering, certain of the selling securityholders, including the Spring Valley Founders and the Legacy NuScale Equityholders, may still have an incentive to sell shares of Class A Common Stock because they purchased the shares at prices lower than the price paid by the purchasers of Spring Valley Class A ordinary shares sold in the Spring Valley initial public offering or the current trading price of Class A Common Stock. For example, based on the closing price of Class A Common Stock of $7.79 as of May 26, 2023, and assuming all shares had been sold immediately after the Merger at such price, the Spring Valley Founders could have experienced a potential profit of approximately $7.79 per share, or $934,800 in the aggregate; and the Legacy NuScale Equityholders could have realized a potential profit (on average) of approximately $3.05 per share, or $544.1 million in the aggregate. Similarly, if Spring Valley Sponsor, LLC sold Private Placement Warrants for $1.70 per warrant, the closing price of our warrants on May 26, 2023, it would realize a potential profit of approximately $0.70 per warrant, or $6.2 million in the aggregate.

The selling securityholders may offer, sell or distribute all or a portion of the Private Placement Warrants and the shares of Class A Common Stock registered hereby publicly or through private transactions at prevailing market prices or at negotiated prices.

We provide more information about how the selling securityholders may sell their shares in the section entitled “Plan of Distribution.”

We paid certain offering fees and expenses and fees in connection with the registration of the Private Placement Warrants and the Class A Common Stock and will not receive proceeds from the exchange of NuScale LLC Class B Units (and cancellation of a corresponding number of shares of Class B Common Stock) for Class A Common Stock or from the sale of the Private Placement Warrants or shares of Class A Common Stock by the selling securityholders, except with respect to any amounts received by us upon exercise of any warrants. We believe the likelihood that warrant holders will exercise their warrants, and therefore the amount of cash proceeds that we would receive from such exercises, depends on the trading price of Class A Common Stock, which may not exceed the $11.50 warrant exercise price before the warrants expire. In certain circumstances, the warrants can be exercised on a cashless basis. The selling securityholders will bear all commissions and discounts, if any, attributable to their respective sales of warrants or Class A Common Stock.

Class A Common Stock is listed on the New York Stock Exchange (“NYSE”) and trades under the symbol “SMR.” On May 26, 2023, the closing sale price of Class A Common Stock was $7.79 per share. Our warrants are listed on the NYSE and trade under the symbol “SMR.WT.” On May 26, 2023, the closing sale price of our warrants was $1.70 per warrant.

We are an “emerging growth company” as defined under applicable federal securities laws, and therefore are subject to certain reduced public company reporting requirements. Our principal executive offices are located at 6650 SW Redwood Lane, Suite 210, Portland, OR 97224, and our telephone number is (971) 371‑1592.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Certain statements in this prospectus may constitute “forward-looking statements” for purposes of the federal securities laws that are not historical facts and that involve risks and uncertainties that could cause actual results to differ materially from expected or projected results. Our forward-looking statements include, but are not limited to, statements regarding our or our management team’s expectations, hopes, beliefs, intentions or strategies. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words “anticipate,” “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “will,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements in this prospectus may include, for example, statements about:

•our financial and business performance, including financial projections and business metrics;

•our ability to obtain regulatory approvals to deploy our small modular reactor in the United States and abroad;

•forecasts regarding end-customer adoption rates and demand for our products in markets that are new and rapidly evolving;

•macroeconomic conditions;

•developments and projections relating to our competitors and industry;

•our anticipated growth rates and market opportunities;

•the period over which we anticipate existing cash and cash equivalents will be sufficient to fund our operating expenses and capital expenditure requirements;

•the potential for our business development efforts to maximize the potential value of our portfolio; and

•our estimates regarding expenses, future revenue, capital requirements and needs for additional financing.

The forward-looking statements contained in this prospectus are based on current expectations and beliefs concerning future developments and their potential effects on us. There can be no assurance that future developments affecting us will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, those factors described under the heading “Risk Factors.” If one or more of these risks or uncertainties materialize, or if any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. There may be additional risks that we currently consider immaterial or which are unknown. It is not possible to predict or identify all such risks. Except as expressly required by applicable securities laws, we undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. You should not take any statement regarding past trends or activities as a representation that the trends or activities will continue in the future.

SUMMARY

This summary highlights selected information included in this prospectus, including information incorporated by reference, and does not contain all of the information that may be important to you. To understand this offering fully, you should read this entire prospectus, the registration statement of which this prospectus is a part and the documents incorporated by reference herein carefully, including the information set forth under the heading “Risk Factors” and our financial statements.

NuScale

NuScale Power Corporation (“NuScale Corp,” “we,” “our” or “us”) is an advanced nuclear technology company that is developing a small modular nuclear reactor to generate steam for electrical generation, district heating, desalination, hydrogen production and other process heat applications. Our core technology, the NuScale Power Module (“NPM”), can generate 77 million watts of electrical power (“MWe”) and is premised on well-established nuclear technology principles, with a focus on the integration of components, simplification or elimination of systems and use of passive safety features. Our flagship power plant, named VOYGR, is a scalable plant design that can accommodate up to 12 NPMs with a total gross output of 924 MWe. We expect the first VOYGR power plant to be operational in 2029.

Background

NuScale Corp (formerly named “Spring Valley Acquisition Corp.”) was a blank check company incorporated under the laws of the Cayman Islands. On May 2, 2022 (the “Closing Date”), Spring Valley Acquisition Corp (“Spring Valley”), completed the following transactions pursuant to the Agreement and Plan of Merger dated December 13, 2021 (as amended) between Spring Valley, Spring Valley Merger Sub, LLC (“Merger Sub”) and NuScale Power, LLC (“NuScale LLC”): (a) the domestication of Spring Valley as a Delaware corporation and the change of its name to “NuScale Power Corporation”; and (b) the merger (“Merger”) of Merger Sub into NuScale LLC, with NuScale LLC surviving, through which the combined company was reorganized in an “UP-C” structure, with NuScale Corp serving as the sole manager of NuScale LLC. Immediately after the Merger, NuScale LLC was owned in part (indirectly through NuScale Corp) by former public and private shareholders of Spring Valley and in part directly by the historical equity owners of NuScale LLC (the “Legacy NuScale Equityholders”). In connection with the Merger, Spring Valley entered into subscription agreements with certain investors (the “PIPE Investors”), pursuant to which the PIPE Investors purchased an aggregate of 23,700,002 shares of Class A Common Stock for an aggregate purchase price of $235,000,000.

As a result of these transactions, immediately after the Merger, former shareholders of Spring Valley and the PIPE Investors owned shares of Class A Common Stock of NuScale Corp; NuScale Corp held (and continues to hold) NuScale LLC Class A Units with sole management control of NuScale LLC; and the Legacy NuScale Equityholders held NuScale LLC Class B Units and an equal number of shares of Class B Common Stock of NuScale Corp (which represent a right to cast one vote per share at the NuScale Corp level, and carry no economic rights), which they may convert into shares of Class A Common Stock.

Offering

This prospectus registers (1) the issuance of up to 154,720,015 shares Class A Common Stock upon exchange (which Class B Units were originally purchased at various times since 2007 for ascribed prices per unit ranging from approximately $0.00 (for certain incentive awards) to $7.76 per unit, and which, together with Class B Units of NuScale LLC previously exchanged for Class A Common Stock, collectively had a weighted average ascribed purchase price of $4.74 per unit immediately after the Merger) and cancellation of a corresponding number of shares of Class B Common Stock of NuScale Corp, and the resale of most of those shares; (2) the issuance of up to 9,558,701 shares of Class A Common Stock upon the exercise of the redeemable warrants issued in Spring Valley’s initial public offering (“IPO”) and converted in the Merger into warrants to purchase Class A common; (3) the issuance of up to 8,900,000 shares of Class A Common Stock upon the exercise of warrants that were issued in a private placement concurrently with the IPO and converted into warrants to purchase Class A Common Stock (“Private Placement Warrants”) and the resale of such shares; and (4) the resale of up to: 8,900,000 Private Placement Warrants, which were originally purchased for $1.00 per warrant; 22,137,482 shares of Class A Common

Stock, which were originally purchased for approximately $10.00 per share by the PIPE Investors; and 120,000 shares of Class A Common Stock held by former directors of Spring Valley (“Spring Valley Founders”), which were originally purchased for approximately $0.003 per share.

Our issuance of Class A Common Stock in exchange for NuScale LLC Class B Units will not result in proceeds; any net proceeds we receive upon the exercise of warrants will be used for general corporate purposes. The selling securityholders will determine when and how they will dispose of the shares of Class A Common Stock or warrants registered under this prospectus for resale. We will not receive any proceeds from sales by selling securityholders.

RISK FACTORS

Investment in the securities offered pursuant to this prospectus involves risks. You should carefully consider the risk factors related to our business and operations described in Part I, Item 1A of our most recent Annual Report on Form 10-K under the heading “Risk Factors” as updated in Part II, Item 1A of subsequent Quarterly Reports on Form 10-Q under the heading “Risk Factors,” which are incorporated by reference in this prospectus. See “Where You Can Find More Information; Incorporation By Reference” in this prospectus. The risks and uncertainties we have described are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also affect our operations. The occurrence of any of these risks might cause you to lose all or part of your investment in the offered securities.

USE OF PROCEEDS

The issuance of Class A Common Stock in exchange for NuScale LLC Class B Units will not result in proceeds to NuScale. Any net proceeds we receive upon exercise of warrants will be used for general corporate purposes. We believe the likelihood that warrant holders will exercise their warrants, and therefore the amount of cash proceeds that we would receive from such exercises, depends on the trading price of our Class A Common Stock, which may not exceed the $11.50 warrant exercise price before the warrants expire. In certain circumstances, the warrants can be exercised on a cashless basis.

All of the warrants and shares of Class A Common Stock offered by the selling securityholders will be sold by them for their respective accounts. We will not receive any of the proceeds from these sales. The selling securityholders will pay any underwriting fees, discounts, selling commissions, stock transfer taxes, and certain legal expenses incurred by such selling securityholders in disposing of their shares of Class A Common Stock, and we will bear all other costs, fees, and expenses incurred in effecting the registration of the securities covered by this prospectus, including registration and filing fees, NYSE listing fees, and fees and expenses of our legal counsel and our independent registered public accountants.

SELLING SECURITYHOLDERS

This prospectus relates to the resale from time to time of 8,900,000 warrants to purchase Class A Common Stock and an aggregate of 202,912,854 shares of Class A Common Stock. The selling securityholders may from time to time offer and sell any or all of the warrants or shares of Class A Common Stock set forth below pursuant to this prospectus and any accompanying prospectus supplement. When we refer to the “selling securityholders” in this prospectus, we mean the persons listed in the table below, and the pledgees, donees, transferees, assignees, successors, designees, and others who later come to hold any of the selling securityholders’ interest in the Class A Common Stock other than through a public sale (including a sale pursuant to Rule 144). Such selling securityholders may currently hold shares of Class A Common Stock registered pursuant to the registration statement of which this prospectus forms a part, or may receive shares of Class A Common Stock registered pursuant to the registration statement of which this prospectus forms a part upon exchange of NuScale LLC Class B Units for NuScale Class A Common Stock, or upon exercise of a Private Placement Warrant.

Certain of our stockholders, including certain selling securityholders, purchased their shares for amounts below recent trading prices of our Class A Common Stock and our warrants. The Spring Valley Founders paid approximately $1.00 per Private Placement Warrant and $0.003 per share for Class A Common Stock; PIPE Investors paid approximately $10.00 per share for Class A Common Stock; and Legacy NuScale Equityholders paid a weighted average ascribed purchase price of $4.74 per unit for Class B Units (which may be exchanged on a one-for-one basis into shares of Class A Common Stock). For example, based on the closing price of Class A Common Stock of $7.79 as of May 26, 2023, and assuming all shares had been sold immediately after the Merger at such price, the Spring Valley Founders could have experienced a potential profit of approximately $7.79 per share, or $934,800 in the aggregate; and the Legacy NuScale Equityholders could have realized a potential profit (on average) of approximately $3.05 per share, or $544.1 million in the aggregate. Similarly, if Spring Valley Sponsor, LLC sold Private Placement Warrants for $1.70 per warrant, the closing price of our warrants on May 26, 2023, it would realize a potential profit of approximately $0.70 per warrant, or $6.2 million in the aggregate. Purchasers of Class A Common Stock in the offering made by this prospectus may not experience a similar rate of return.

The following table sets forth, as of the date of this prospectus, (i) the names of the selling securityholders, (ii) the number of NuScale LLC Class B Units held by such selling securityholders, if any, before the exchange of such NuScale LLC Class B Units for shares of Class A Common Stock (and cancellation of a corresponding number of shares of Class B Common Stock), (iii) the number of shares of Class A Common Stock, Class B Common Stock and Private Placement Warrants held by such selling securityholders prior to any exchange by them of NuScale LLC Class B Units (and cancellation of a corresponding number of shares of Class B Common Stock), (iv) the aggregate number of shares of Class A Common Stock that will be owned by such selling securityholders after the exchange of NuScale LLC Class B Units held by them (and cancellation of a corresponding number of shares of Class B Common Stock) and the exercise of Private Placement Warrants, and (v) the aggregate number of shares of Class A Common Stock that will be owned by such selling securityholders following the sale of shares in this offering. The percentage ownership of shares of Class A Common Stock is based on an aggregate of 228,229,811 shares of NuScale Class A Common Stock and NuScale Class B Common Stock issued and outstanding as of May 26, 2023.

For purposes of the table below, we have assumed that the selling securityholders will not acquire beneficial ownership of any additional securities during the offering. The following table is prepared based on information provided to us by the selling securityholders. In addition, we assume that the selling securityholders have not sold, transferred or otherwise disposed of, our securities in transactions exempt from the registration requirements of the Securities Act. Any changed or new information given to us by the selling securityholders, including regarding the identity of, and the securities held by, each selling securityholder, will be set forth in a prospectus supplement or amendments to the registration statement of which this prospectus is a part, if and when necessary.

We have determined beneficial ownership in accordance with the rules of the SEC. The information in the table below was determined upon review of the records and public filings available to us, and may not reflect information not found in these sources. Beneficial ownership generally includes voting or investment power over securities. Except in cases where community property laws apply or as indicated in the footnotes to this table, we believe that each selling securityholder identified in the table possesses sole voting and investment power over the shares of

Class A Common Stock shown as beneficially owned by the selling securityholder. The information is not necessarily indicative of beneficial ownership for any other purpose.

PLAN OF DISTRIBUTION

We are registering (i) 202,912,854 shares of Class A Common Stock for possible sale by the selling securityholders from time to time (which includes up to 8,900,000 shares of Class A Common Stock that are issuable upon the exercise of Private Placement Warrants by the holders thereof) and (ii) up to 8,900,000 Private Placement Warrants for possible sale by the selling securityholders from time to time. We are required to pay all fees and expenses incident to the registration of the shares of Class A Common Stock and Private Placement Warrants to be offered and sold pursuant to this prospectus. The selling securityholders will bear all commissions and discounts, if any, attributable to their sale of shares of Class A Common Stock and Private Placement Warrants.

The selling securityholders, which as used herein include donees, pledgees, transferees, distributees, or other successors-in-interest selling shares of our Class A Common Stock or Private Placement Warrants or interests in our Class A Common Stock or private placement warrants received after the date of this prospectus from the selling securityholders as a gift, pledge, distribution, or other transfer, may, from time to time, sell, transfer, distribute, or otherwise dispose of certain of their shares of Class A Common Stock or Private Placement Warrants or interests in our Class A Common Stock or Private Placement Warrants on any stock exchange, market, or trading facility on which shares of our Class A Common Stock or Private Placement Warrants, as applicable, are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market prices, at varying prices determined at the time of sale, or at negotiated prices.

Each selling securityholder will act independently of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made on one or more exchanges or in the over-the-counter market or otherwise, at prices and under terms then prevailing or at prices related to the then current market price or in negotiated transactions.

The selling securityholders may use any one or more of the following methods when disposing of their securities or interests therein:

•ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

•one or more underwritten offerings;

•block trades in which the broker-dealer will attempt to sell the securities as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

•purchases by a broker-dealer as principal and resale by the broker-dealer for its accounts;

•an exchange distribution in accordance with the rules of the applicable exchange;

•privately negotiated transactions;

•in market transactions, including transactions on a national securities exchange or quotations service or over-the-counter market;

•through trading plans entered into by a selling securityholder pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of their securities on the basis of parameters described in such trading plans;

•in “at the market” offerings, as defined in Rule 415 under the Securities Act, at negotiated prices, at prices prevailing at the time of sale or at prices related to such prevailing market prices, including sales made directly on a national securities exchange or sales made through a market maker other than on an exchange or other similar offerings through sales agents;

•through agents;

•broker-dealers who may agree with the selling securityholders to sell a specified number of such securities at a stipulated price per share or warrant;

•a combination of any such methods of sale;

•any other method permitted pursuant to applicable law.

The selling securityholders may, from time to time, pledge or grant a security interest in some shares of our Class A Common Stock or Private Placement Warrants owned by them and, if a selling securityholder defaults in the performance of its secured obligations, the pledgees or secured parties may offer and sell such securities, from time to time, under this prospectus, or under an amendment or supplement to this prospectus amending the list of the selling securityholders to include the pledgee, transferee, or other successors-in-interest as the selling securityholders under this prospectus. The selling securityholders also may transfer securities in other circumstances, in which case the transferees, pledgees, or other successors-in-interest will be the selling beneficial owners for purposes of this prospectus.

In connection with the sale of shares of our Class A Common Stock or Private Placement Warrants or interests therein, the selling securityholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of such securities in the course of hedging the positions they assume. The selling securityholders may also sell shares of our Class A Common Stock or Private Placement Warrants short and deliver these securities to close out their short positions, or loan or pledge shares of our Class A Common Stock or Private Placement Warrants to broker-dealers that in turn may sell these securities. The selling securityholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities that require the delivery to such broker-dealer or other financial institution of shares of our Class A Common Stock or Private Placement Warrants offered by this prospectus, which shares or warrants such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

We will not receive any of the proceeds from the sale of the securities by the selling securityholders. We will receive proceeds from warrants exercised for cash. The aggregate proceeds to the selling securityholders from the sale of shares of our Class A Common Stock or Private Placement Warrants offered by them will be the purchase price of such securities, less discounts or commissions, if any. The selling securityholders reserve the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of shares of our Class A Common Stock or Private Placement Warrants to be made directly or through agents. We will not receive any of the proceeds from any offering by the selling securityholders.

A selling securityholder may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by any selling securityholder or borrowed from any selling securityholder or others to settle those sales or to close out any related open borrowings of shares of Class A Common Stock or Private Placement Warrants, and may use securities received from any selling securityholder in settlement of those derivatives to close out any related open borrowings of securities. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, any selling securityholder may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities

short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

The selling securityholders also may in the future resell a portion of our Class A Common Stock or Private Placement Warrants in open-market transactions in reliance upon Rule 144 under the Securities Act (provided that they meet the criteria and conform to the requirements of that rule), or pursuant to other available exemptions from the registration requirements of the Securities Act.

The selling securityholders and any underwriters, broker-dealers, or agents that participate in the sale of shares of our Class A Common Stock or Private Placement Warrants or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions, or profit they earn on any resale of such securities may be underwriting discounts and commissions under the Securities Act. If any selling securityholder is an “underwriter” within the meaning of Section 2(11) of the Securities Act, then the selling securityholder will be subject to the prospectus delivery requirements of the Securities Act. Underwriters and their controlling persons, dealers, and agents may be entitled, under agreements entered into with us and the selling securityholders, to indemnification against and contribution toward specific civil liabilities, including liabilities under the Securities Act.

To the extent required, the number of shares of our Class A Common Stock or Private Placement Warrants to be sold, the respective purchase prices and public offering prices, the names of any agent, dealer, or underwriter, and any applicable discounts, commissions, concessions, or other compensation with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

To facilitate the offering of securities offered by the selling securityholders, certain persons participating in the offering may engage in transactions that stabilize, maintain, or otherwise affect the price of our Class A Common Stock or warrants. This may include over-allotments or short sales, which involve the sale by persons participating in the offering of more shares of Class A Common Stock or warrants than were sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option, if any. In addition, these persons may stabilize or maintain the price of our Class A Common Stock or warrants by bidding for or purchasing shares of Class A Common Stock or warrants in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if shares of Class A Common Stock or warrants sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of our Class A Common Stock or warrants at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

The selling securityholders may solicit offers to purchase the securities directly from, and it may sell such securities directly to, institutional investors or others. In this case, no underwriters or agents would be involved. The terms of any of those sales, including the terms of any bidding or auction process, if utilized, will be described in the applicable prospectus supplement.

It is possible that one or more underwriters may make a market in our securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for our securities. Our Class A Common Stock is listed on the NYSE under the symbol “SMR” and our warrants are listed on the NYSE under the symbol “SMR.WT”.

The selling securityholders may authorize underwriters, broker-dealers or agents to solicit offers by certain purchasers to purchase the securities at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we or the selling securityholders pay for solicitation of these contracts.

In effecting sales, broker-dealers or agents engaged by the selling securityholders may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the selling securityholders in amounts to be negotiated immediately prior to the sale.

In compliance with the guidelines of the Financial Industry Regulatory Authority (“FINRA”), the aggregate maximum discount, commission, fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed 8% of the gross proceeds of any offering pursuant to this prospectus and any applicable prospectus supplement.

If at the time of any offering made under this prospectus a member of FINRA participating in the offering has a “conflict of interest” as defined in FINRA Rule 5121 (“Rule 5121”), that offering will be conducted in accordance with the relevant provisions of Rule 5121.

Item 15. Indemnification of Directors and Officers.

Section 145(a) of the General Corporation Law of the State of Delaware (the “DGCL”) provides, in general, that a corporation may indemnify any person who was or is a party to or is threatened to be made a party to any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative (other than an action by or in the right of the corporation), because he or she is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise, against expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit, or proceeding, if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

Section 145(b) of the DGCL provides, in general, that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or completed action or suit by or in the right of the corporation to procure a judgment in its favor because the person is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made with respect to any claim, issue, or matter as to which he or she shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances of the case, he or she is fairly and reasonably entitled to indemnity for such expenses that the Court of Chancery or other adjudicating court shall deem proper.

Section 145 of the DGCL further provides that to the extent a director or officer of a corporation has been successful on the merits or otherwise in the defense of any action, suit, or proceeding referred to in Section 145(a) or (b) of the DGCL, or in defense of any claim, issue, or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith; that indemnification provided for by Section 145 of the DGCL shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and the indemnification provided for by Section 145 of the DGCL shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee, or agent and shall inure to the benefit of such person’s heirs, executors, and administrators. Section 145(g) of the DGCL provides, in general, that a corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture,

II-1

trust, or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify the person against such liability under Section 145 of the DGCL.

Section 102(b)(7) of the DGCL provides that a corporation’s certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director or officer to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, provided that such provision shall not eliminate or limit liability (i) for any breach of the duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) of a director under Section 174 of the DGCL, (iv) for any transaction from which the director derived an improper personal benefit, or (v) of an officer in an action by or in the right of the corporation.

Additionally, the registrant’s certificate of incorporation (the “Certificate of Incorporation”) and bylaws (the “Bylaws”) limit the liability of the registrant’s directors and officers to the fullest extent permitted by the DGCL, and provide that the registrant will indemnify its directors and officers to the fullest extent permitted by the DGCL.

The registrant has entered into and expects to continue to enter into agreements to indemnify its directors, executive officers, and other employees as determined by its board of directors. Under the terms of such indemnification agreements, the registrant is required to indemnify each of its directors and officers, to the fullest extent permitted by the laws of the state of Delaware, if the basis of the indemnitee’s involvement was by reason of the fact that the indemnitee is or was the registrant’s director or officer or was serving at the registrant’s request in an official capacity for another entity. The registrant must indemnify its officers and directors against all reasonable fees, expenses, charges, and other costs of any type or nature whatsoever, including any and all expenses and obligations paid or incurred in connection with investigating, defending, being a witness in, participating in (including on appeal), or preparing to defend, be a witness, or participate in any completed, actual, pending, or threatened action, suit, claim, or proceeding, whether civil, criminal, administrative, or investigative, or establishing or enforcing a right to indemnification under the indemnification agreement. The indemnification agreements also require the registrant, if so requested, to advance all reasonable fees, expenses, charges, and other costs that such director or officer incurred; provided that such person will return any such advance if it is ultimately determined that such person is not entitled to indemnification by the registrant. Any claims for indemnification by the registrant’s directors and officers may reduce its available funds to satisfy successful third-party claims against the registrant and may reduce the amount of money available to the registrant.

The registrant also maintains a general liability insurance policy, which covers certain liabilities of directors and officers of the registrant arising out of claims based on acts or omissions in their capacities as directors or officers.

Item 17. Undertakings.

(a)The undersigned registrant hereby undertakes:

(1)to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)to include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii)to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement (notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any

II-2

deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement); and

(iii)to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that clauses (i), (ii) and (iii) do not apply if the registration statement is on Form S-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended, that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement;

(2)that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(3)to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering;

(4)that, for the purpose of determining liability under the Securities Act to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use; and

(5)that, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of an undersigned registrant; and

(iv)any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

II-3

(b)Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
