PROSPECTUS

228,011,646 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 178,396,711 shares (“Exchange 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 collectively have a weighted average ascribed purchase price of $4.74 per unit) 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 Exchange Shares, the resale of which might otherwise be limited by the resale restrictions imposed on “control securities” under Rule 144 under the Securities Act; (2) the issuance by us of up to 11,500,000 shares of Class A Common Stock upon the exercise of the NuScale Corp Public Warrants (as defined below); (3) the issuance by us of up to 8,900,000 shares of Class A Common Stock upon the exercise of NuScale Corp Private Placement Warrants (defined below) 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 NuScale Corp Private Placement Warrants (as defined below) to purchase Class A Common Stock, which NuScale Corp Private Placement Warrants were originally purchased for $1.00 per warrant; 23,700,002 shares of Class A Common Stock, which were originally purchased for approximately $10.00 per share by PIPE Investors (defined below) immediately prior to the consummation of the Merger (defined below) pursuant to the terms of the Subscription Agreements (defined below); and 5,514,933 shares of Class A Common Stock held by Spring Valley Acquisition Sponsor Sub, LLC and its affiliates and the former officers and directors of Spring Valley Acquisition Corp (“Spring Valley Founders”), which were originally purchased for approximately $0.003 per share and 1,643,924 of which are subject to potential forfeiture.

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 (the “Domestication”) and the change of its name to “NuScale Power Corporation”; and (b) the merger (“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. NuScale LLC is now 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 certain selling securityholders, 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 our 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 common stock being offered for resale pursuant to this prospectus by the selling securityholders represent approximately 85.5% of shares outstanding on a fully diluted basis as of June 9, 2022, 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 our Class A Common Stock or result in a significant decline in the public trading price of our Class A Common Stock. Even if our trading price is significantly below $10.00, the offering price for the units 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 our Class A Common Stock because they purchased the shares at prices lower than the price paid by the Public Shareholders (defined below) or the current trading price of our Class A Common Stock. For example, based on the closing price of our Class A Common Stock of $9.96 as of June 9, 2022, the Spring Valley Founders could experience a potential profit of up to approximately $9.96 per share, or $54.9 million in the aggregate.

The selling securityholders may offer, sell or distribute all or a portion of the NuScale Corp 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 will pay certain offering fees and expenses and fees in connection with the registration of the NuScale Corp 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 NuScale Corp 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 NuScale Corp 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 our Class A Common Stock, which may not exceed the $11.50 warrant exercise price before the warrants expire. In certain circumstances, the NuScale Corp Warrants can be exercised on a cashless basis. See “Description of Capital Stock —Warrants.” The selling securityholders will bear all commissions and discounts, if any, attributable to their respective sales of the NuScale Private Placement Warrants or the Class A Common Stock.

Our Class A Common Stock is listed on the New York Stock Exchange (“NYSE”) and trades under the symbol “SMR.” On June 9, 2022, the closing sale price of our Class A Common Stock was $9.96 per share. Our public warrants are listed on the NYSE and trade under the symbol “SMR WS.” June 9, 2022, the closing sale price of our public warrants was $2.57 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.

BASIS OF PRESENTATION

We were incorporated on August 20, 2020 as a Cayman Islands exempted company under the name Spring Valley Acquisition Corp. for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses. On May 2, 2022, we completed the Transactions (as defined herein), following which we were renamed “NuScale Power Corporation,” and we act as the sole manager of NuScale Power, LLC, an Oregon limited liability company (“NuScale LLC”). Unless otherwise indicated, the financial information included herein is that of NuScale LLC, which, following the Transactions, became our business. We are a holding company and, accordingly, all of our assets are held directly by, and all of our operations are conducted through, NuScale LLC, and our only direct asset consists of NuScale LLC Class A Units. As the manager of NuScale LLC, we have the full, exclusive, and complete discretion to manage and control the business of NuScale LLC and to take all action we deem necessary, appropriate, advisable, incidental, or convenient to accomplish the purposes of NuScale LLC set forth in its operating agreement. We may not be removed as the manager of NuScale LLC.

Because we had limited operations before the Transactions, NuScale LLC is our “predecessor” for financial reporting purposes and we present in this prospectus pro forma condensed consolidated financial statements that give effect to the Merger in the historical periods presented. The financial statements of NuScale LLC for periods following the Transactions will be prepared on a consolidated basis with ours.

TABLE OF CONTENTS

Certain monetary amounts, percentages and other figures included in this prospectus have been subject to rounding adjustments. Accordingly, figures shown as totals in certain tables and charts may not be the arithmetic aggregation of the figures that precede them, and figures expressed as percentages in the text may not total 100% or, as applicable, when aggregated may not be the arithmetic aggregation of the percentages that precede them.

Unless the context otherwise requires, references in this prospectus to the “Company,” “NuScale,” “we,” “us,” or “our” refer to the business of NuScale LLC, which became the business of NuScale Power Corporation following the consummation of the Transactions.

MARKET AND INDUSTRY DATA

This prospectus includes, and any amendment or supplement to this prospectus may include, estimates regarding market and industry data and forecasts, which are based on our own estimates utilizing our management’s knowledge of and experience in, as well as information obtained from trade and business organizations, and other contacts in the market sectors in which we compete, and from statistical information obtained from publicly available information, industry publications and surveys, reports from government agencies, and reports by market research firms. We confirm that, where such information is reproduced herein, such information has been accurately reproduced and that, so far as we are aware and are able to ascertain from information published by publicly available sources and other publications, no facts have been omitted that would render the reproduced information inaccurate or misleading. Industry publications, reports, and other published data generally state that the information contained therein has been obtained from sources believed to be reliable, but we cannot assure you that the information contained in these reports, and therefore the information contained in this prospectus or any amendment or supplement to this prospectus that is derived therefrom, is accurate or complete. Our estimates of our market position may prove to be inaccurate because of the method by which we obtain some of the data for our estimates or because this information cannot always be verified with complete certainty due to the limits on the availability and reliability of raw data, the voluntary nature of the data gathering process, and other limitations and uncertainties. As a result, although we believe our sources are reliable, we have not independently verified the information and cannot guarantee its accuracy and completeness.

Background

NuScale Power Corporation (formerly named “Spring Valley Acquisition Corp.”) was a blank check company incorporated under the laws of the Cayman Islands. Spring Valley, Merger Sub and NuScale LLC entered into Merger Agreement on December 13, 2021, as amended, and the following transactions contemplated by the Merger Agreement were completed on May 2, 2022:

•

Spring Valley changed its jurisdiction of incorporation by deregistering as an exempted company in the Cayman Islands, domesticated as a corporation under the laws of the State of Delaware, and changed its name to “NuScale Power Corporation”;

•

NuScale Corp was designated as the sole manager of NuScale LLC;

•

Merger Sub merged into NuScale LLC with NuScale LLC surviving; and

•

the combined company was organized in an “UP-C” structure, in which substantially all of the assets and business of the combined company are held by NuScale LLC.

As a result of these transactions, former public shareholders of Spring Valley own shares of Class A Common Stock of NuScale Corp; NuScale Corp and the Legacy NuScale Equityholders hold NuScale LLC Class A Units and NuScale LLC Class B Units, respectively; and Legacy NuScale Equityholders hold a number of shares of Class B Common Stock (which represent a right to cast one vote per share at the NuScale Corp level, and carry no economic rights) equal to the number of NuScale LLC Class B Units held by the Legacy NuScale Equityholders.

This registration statement registers for resale 8,900,000 NuScale Corp Private Placement Warrants to purchase Class A Common Stock, which NuScale Corp Private Placement Warrants were originally purchased for $1.00 per warrant, and up to an aggregate of 209,870,307 shares of Class A Common Stock composed of: (a) 171,755,372 shares of Class A Common Stock issuable upon exchange (on a one-for-one basis, subject to adjustment) of Class B Units of 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 collectively have a weighted average ascribed purchase price of $4.74 per unit; (b) 23,700,002 shares of Class A Common Stock, which were originally purchased for approximately $10.00 per share issued in private placements by PIPE Investors; and (c) 5,514,933 shares of Class A Common Stock held by Spring Valley Founders, which were originally purchased for approximately $0.003 per share and 1,643,924 of which are subject to potential forfeiture.

TABLE OF CONTENTS

Even if our trading price is significantly below $10.00, the offering price for the units offered in the Company’s initial public offering, certain of the selling securityholders, including the Spring Valley Founders, may still have an incentive to sell shares of our Class A Common Stock because they purchased the shares at prices lower than the Public Shareholders or the current trading price of our Class A Common Stock. For example, based on the closing price of our Class A Common Stock of $9.96 as of June 9, 2022, the Spring Valley Founders could experience a potential profit of approximately $9.96 per share, or $54.9 million in the aggregate; the PIPE Investors would realize a potential loss of approximately $0.04 per share, or $0.9 million in the aggregate; and the Legacy NuScale Equityholders would realize a potential profit (on average) of approximately $5.22 per share, or $931.1 million in the aggregate. Similarly, if the Spring Valley Founders sold NuScale Corp Private Placement Warrants for $2.57 per warrant, the closing price of our warrants on June 9, 2022, the Spring Valley Founders would realize a potential profit of approximately $1.57 per warrant, or $14.0 million in the aggregate. Purchasers of Class A Common Stock or NuScale Corp Private Placement Warrants in the offering made by this prospectus may not experience a similar rate of return. See “Risk Factors — Risks Related to this Offering and Ownership of Our Shares of Class A Common Stock or NuScale Corp Warrants — You may not experience a rate of return on your investment in Class A Common Stock similar to the return experienced by existing stockholders, including those who hold shares that are registered for resale under this registration statement.”

Summary of Risk Factors (page 9)

The investment in our securities involve significant risks, and you should carefully read and consider the factors discussed under “Risk Factors.” The following is a summary of some of these risks. If any of the following events occur, our business, financial condition and operating results may be materially adversely affected. In that event, the trading price of our securities could decline, and you could lose all or part of your investment.

Risks Related to Our Structure and Governance

•

We are subject to risks related to our dependency on NuScale LLC to pay taxes, make payments under the Tax Receivable Agreement and pay dividends;

•

If NuScale LLC were treated as a corporation for United States federal income tax or state tax purposes, then the amount available for distribution by NuScale LLC could be substantially reduced and the value of NuScale Corp shares could be adversely affected;

•

In certain cases, payments under the Tax Receivable Agreement may be accelerated and/or significantly exceed the actual tax benefits NuScale Corp realizes;

•

NuScale Corp is a “controlled company” under the NYSE listing standards, and as a result, its stockholders may not have certain corporate protections that are available to stockholders of companies that are not controlled companies; and

•

Spring Valley identified a material weakness in its internal control over financial reporting. This material weakness could continue to adversely affect NuScale Corp’s ability to report its results of operations and financial condition accurately and in a timely manner.

Risks Related to NuScale LLC’s Business and Industry

•

NuScale LLC has not yet delivered an NPM to a customer or entered into a binding contract with a customer to deliver NPMs, and there is no guarantee that it will be able to do so;

•

Competitors in China and Russia currently operate commercial SMRs and may have advantages in marketing their SMRs to potential customers;

•

NuScale LLC may be unable to charge Utah Associated Municipal Power Systems (UAMPS), its first customer, for some costs NuScale LLC has incurred and it may be required to reimburse UAMPS if NuScale LLC fails to achieve specified performance measures;

•

Any delays in the development and manufacture of NPMs and related technology, the failure of any commercial or demonstration missions, or the failure to timely deliver NPMs to customers may adversely impact NuScale LLC’s business and financial condition;

TABLE OF CONTENTS

•

NuScale LLC has incurred significant losses since inception, expects to incur losses in the future, and may not be able to achieve or maintain profitability;

•

The cost of electricity generated from nuclear sources may not be cost competitive with other electricity generation sources in some markets, and NuScale LLC may fail to effectively incorporate updates to the design, construction, and operations of NuScale LLC plants to ensure cost competitiveness, which could materially and adversely affect NuScale LLC’s business;

•

The market for SMRs is not yet established and may not achieve the growth potential expected or may grow more slowly than expected;

•

NuScale LLC’s commercialization strategy relies heavily on its relationship with Fluor, and other strategic investors and partners, who may have interests that diverge from NuScale LLC and who may not be easily replaced if their relationships terminate;

•

NuScale LLC may be unable to manage its future growth effectively, which could make it difficult to execute its business strategy;

•

If manufacturing and construction issues are not identified prior to design finalization, long-lead procurement, and/or module fabrication, then those issues will be realized during production, fabrication, or construction and may impact plant deployment cost and schedule;

•

NuScale LLC and its customers operate in a politically sensitive environment, and may be affected by the public perception of nuclear energy and accidents, terrorist attacks or other high-profile events involving nuclear materials;

•

NuScale LLC’s supply base may not be able to scale to the production levels necessary to meet sales projections, and a lack of availability and cost of component raw materials may affect the manufacturing processes for plant equipment and increase NuScale LLC’s costs;

•

NuScale LLC is highly dependent on its senior management team and other highly skilled personnel, and may not be able to successfully implement its business strategy if it is unable to attract highly qualified personnel;

•

NuScale LLC may require additional future funding, which may be difficult or impossible to obtain on acceptable terms or at all and which may be negatively affected by the resale of shares of Class A Common Stock by selling securityholders pursuant to this prospectus which could result in a significant decline in the trading price of our Class A Common Stock;

•

NuScale LLC may be unable to adequately protect its intellectual property rights, in particular its rights in non-U.S. jurisdictions, and may be subject to infringement claims from others;

•

NuScale LLC’s SDA (defined below) application for the 77 MWe power module has not yet been submitted to the NRC, and its approval is not guaranteed;

•

NuScale LLC’s design is only approved in the United States and it must obtain approvals on a country- by-country basis before it can sell its products abroad, which approvals may be delayed or denied or which may require modification to its design;

•

NuScale LLC’s customers must obtain additional, site-specific regulatory approvals before they can construct power plants using NPMs, which may be delayed or denied; and

•

NuScale LLC’s business is subject to a wide variety of extensive and evolving laws and regulations — including export and import controls, nuclear material and nuclear power regulations, and environmental regulations — and changes in and/or failure to comply with such laws and regulations could have a material adverse effect on its business.

Risks Related to this Offering and Ownership of Our Shares of Class A Common Stock and NuScale Corp Warrants

•

We are subject to risks related to the volatility of the price of our Class A Common Stock and NuScale Corp Warrants;

TABLE OF CONTENTS

•

The resale of shares registered by this registration statement, which represent a majority of the shares that are or will be outstanding, or of other shares that are freely tradeable could cause the market price of our Class A Common Stock to drop significantly;

•

NuScale Corp Warrants are exercisable for Class A Common Stock, which, if exercised, would increase the number of shares eligible for future resale in the public market and result in dilution to our stockholders; and

•

A market for shares of the Class A Common Stock may fail to develop.

Emerging Growth Company Status

Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) exempts emerging growth companies (“EGCs”) from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a registration statement under the Securities Act declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with such standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-EGCs but any such election to opt out is irrevocable. We intend to take advantage of the benefits of this extended transition period.

We will remain an EGC until the earlier of: (1) the last day of the fiscal year (a) 2025, (b) in which we have total annual gross revenue of at least $1.07 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common equity that is held by non-affiliates exceeds $700 million as of the end of the prior fiscal year’s second fiscal quarter; and (2) the date on which we have issued more than $1.00 billion in non-convertible debt securities during the prior three-year period. We expect to remain an EGC until December 31, 2025, the last day of the fiscal year following the fifth anniversary of the completion of our IPO on November 27, 2020.

The resale of the following securities owned by selling securityholders comprising the Sponsor and its affiliates: up to 5,514,933 shares of Class A Common Stock, and up to 8,900,000 NuScale Corp Private Placement Warrants to purchase Class A Common Stock.

Term of the Offering

We may issue shares of Class A Common Stock upon the exchange of NuScale LLC Class B Units pursuant to the terms of the A&R NuScale LLC Agreement, and upon exercise of NuScale Corp Warrants.

The selling securityholders will determine when and how they will dispose of any shares of Class A Common Stock registered under this prospectus for resale.

The selling securityholders will pay any underwriting fees, discounts, selling commissions, stock transfer taxes, and certain legal expenses incurred by them 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 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.

Use of Proceeds

We will not receive any proceeds from sales by selling securityholders, except with respect to any amounts received by us upon exercise of any NuScale Corp Warrants. The exercise price of the NuScale Corp Warrants is $11.50 per warrant. We believe the likelihood that warrant holders will exercise the NuScale Corp 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.

SUMMARY HISTORICAL AND PRO FORMA
FINANCIAL INFORMATION AND OTHER DATA

The following table presents the summary historical combined financial and other data for NuScale LLC and its subsidiaries and the summary pro forma condensed consolidated financial data for NuScale Corp for the periods and at the dates indicated. NuScale Corp is a holding company, and its sole material asset is a controlling equity interest in NuScale LLC. NuScale Corp operates and controls all of the business and affairs of NuScale LLC and, through NuScale LLC and its subsidiaries, conducts our business. NuScale LLC is the predecessor of NuScale Corp for financial reporting purposes. As a result, the consolidated financial statements of NuScale Corp will recognize the assets and liabilities received in the reorganization at their historical carrying amounts, as reflected in the historical financial statements of NuScale LLC. NuScale Corp will consolidate NuScale LLC in its consolidated financial statements and record a non-controlling interest related to the NuScale LLC Common Units held by the members of NuScale LLC on its consolidated balance sheet and statement of operations. The summary statements of operations data and summary statements of cash flows data presented below for the years ended December 31, 2020 and 2021 and the summary balance sheet data presented below as of December 31, 2020 and 2021 have been derived from the financial statements of NuScale LLC included elsewhere in this prospectus. The summary financial information of NuScale LLC as of March 31, 2021 and for the three months ended March 31, 2021 and 2022 was derived from the unaudited condensed financial statements of NuScale LLC included elsewhere in this prospectus. The unaudited condensed financial statements of NuScale LLC have been prepared on the same basis as the audited financial statements and, in our opinion, have included all adjustments, which include normal recurring adjustments, necessary to present fairly in all material respects our financial position and results of operations. The results for any interim period are not necessarily indicative of the results that may be expected for the full year.

The summary historical consolidated financial and other data of NuScale Corp has not been presented because, prior to the consummation of the Transactions, NuScale Corp was a blank check company with no business transactions or activities, and assets or liabilities, during the periods presented, other than those activities, assets, and liabilities related to its search for a potential initial business combination.

Historical results are not necessarily indicative of the results expected for any future period. You should read the summary historical consolidated financial data below, together with our audited consolidated financial statements and related notes thereto, the audited financial statements of Spring Valley and related notes thereto, our unaudited consolidated financial statements and related notes thereto, and the unaudited financial statements of Spring Valley and related notes thereto, each included elsewhere in this prospectus, as well as “Unaudited Pro Forma Condensed Consolidated Financial Information,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and the other information appearing elsewhere in this prospectus.

The summary unaudited pro forma condensed consolidated financial data of NuScale Corp presented below have been derived from our unaudited pro forma condensed consolidated financial statements included elsewhere in this prospectus. The summary unaudited pro forma condensed consolidated statements of operations data for the three months ended March 31, 2022 and the year ended December 31, 2021 give effect to the Transactions as if they had occurred on January 1, 2021. The summary unaudited pro forma condensed consolidated balance sheet data as of March 31, 2022 gives effect to the Transactions as if they had occurred on March 31, 2022.

The summary unaudited condensed consolidated pro forma financial data is presented for illustrative purposes only and is not necessarily indicative of the operating results or financial position that would have occurred if the relevant transactions had been consummated on the dates indicated, nor is it indicative of future operating results or financial position. Spring Valley and NuScale LLC have not had any historical relationship prior to the Transactions. Accordingly, no pro forma adjustments were required to eliminate activities between the companies. The financial results may have been different had the companies always been combined. See “Unaudited Pro Forma Condensed Consolidated Financial Information.”

RISK FACTORS

We have identified the following risks and uncertainties that may have a material adverse effect on our business, financial condition, results of operations or reputation. The risks described below are not the only risks we face. Additional risks not presently known to us or that we currently believe are not material may also significantly affect our business, financial condition, results of operations or reputation. Our business could be harmed by any of these risks. In assessing these risks, you should also refer to the other information contained in this prospectus, including our financial statements and related notes.

Risks Related to Our Structure and Governance

NuScale Corp is a holding company and its only material asset is its interest in NuScale LLC, and it is accordingly dependent upon distributions made by its subsidiaries to pay taxes, make payments under the Tax Receivable Agreement and pay dividends.

NuScale Corp is a holding company with no material assets other than its ownership of the NuScale LLC Common Units. As a result, NuScale Corp has no independent means of generating revenue or cash flow. NuScale Corp’s ability to pay taxes, cause NuScale LLC to make payments under the Tax Receivable Agreement, and pay dividends depends on the financial results and cash flows of NuScale LLC and the distributions it receives (directly or indirectly) from NuScale LLC. Deterioration in the financial condition, earnings or cash flow of NuScale LLC for any reason could limit or impair its ability to pay such distributions. Additionally, to the extent that NuScale Corp needs funds and NuScale LLC is restricted from making such distributions under applicable law or regulation or under the terms of any financing arrangements, or NuScale LLC is otherwise unable to provide such funds, it could materially adversely affect NuScale Corp’s liquidity and financial condition.

Subject to the discussion herein, NuScale LLC is treated as a partnership for United States federal income tax purposes and, as such, generally will not be subject to any entity-level United States federal income tax. Instead, taxable income will be allocated to holders of NuScale LLC Common Units. Accordingly, NuScale Corp will be required to pay income taxes on its allocable share of any net taxable income from NuScale LLC. Under the terms of the A&R NuScale LLC Agreement, NuScale LLC is obligated to make tax distributions to holders of the NuScale LLC Common Units calculated at certain assumed tax rates. In addition to income taxes, NuScale Corp is also expected to incur expenses related to its operations, including payment obligations under the Tax Receivable Agreement, which could be significant, and some of which will be reimbursed by NuScale LLC (excluding payment obligations under the Tax Receivable Agreement). NuScale Corp intends to cause NuScale LLC to make ordinary distributions and tax distributions to holders of the NuScale LLC Class A Units and NuScale LLC Class B Units on a pro rata basis in amounts sufficient to cover all applicable taxes, relevant operating expenses, payments under the Tax Receivable Agreement and dividends, if any, declared by NuScale Corp. However, as discussed above, NuScale LLC’s ability to make such distributions may be subject to various limitations and restrictions, including, but not limited to, retention of amounts necessary to satisfy the obligations of NuScale LLC and restrictions on distributions that would violate any applicable restrictions contained in NuScale LLC’s debt agreements, if any, any applicable law or that would have the effect of rendering NuScale LLC insolvent. To the extent that NuScale Corp is unable to make payments under the Tax Receivable Agreement for any reason, such payments will be deferred and will accrue interest until paid; provided, however, that nonpayment for a specified period may constitute a breach of a material obligation under the Tax Receivable Agreement and therefore accelerate payments under the Tax Receivable Agreement, which could be substantial.

Additionally, although NuScale LLC generally will not be subject to any entity-level United States federal income tax, it may be liable under recent United States federal tax legislation for adjustments to prior year tax returns, absent an election to the contrary. In the event NuScale LLC’s calculations of taxable income are incorrect, NuScale LLC and its members, including NuScale Corp, in later years may be subject to material liabilities pursuant to this legislation and its related guidance.

An entity that would otherwise be classified as a partnership for United States federal income tax purposes (such as NuScale LLC) may nonetheless be treated as, and taxable as, a corporation if it is a

TABLE OF CONTENTS

“publicly traded partnership” unless an exception to such treatment applies. An entity that would otherwise be classified as a partnership for United States federal income tax purposes will be treated as a “publicly traded partnership” if interests in such entity are traded on an established securities market or interests in such entity are readily tradable on a secondary market or the substantial equivalent thereof. If NuScale LLC is determined to be treated as a “publicly traded partnership” (and taxable as a corporation) for United States federal income tax purposes, it would be taxable on its income at the United States federal income tax rates applicable to corporations and distributions by NuScale LLC to its partners (including NuScale Corp) could be taxable as dividends to such partners to the extent of the earnings and profits of NuScale LLC. In addition, we would no longer have the benefit of increases in the tax basis of NuScale LLC’s assets as a result of exchanges of NuScale LLC Class B Units. Pursuant to the A&R NuScale LLC Agreement, certain Legacy NuScale Equityholders may, from time to time, subject to the terms of the A&R NuScale LLC Agreement, exchange their interests in NuScale LLC and have such interests redeemed by NuScale LLC for cash or Class A Common Stock. While such exchanges could be treated as trading in the interests of NuScale LLC for purposes of testing “publicly traded partnership” status, the A&R NuScale LLC Agreement contains restrictions on redemptions and exchanges of interests in NuScale LLC that are intended to prevent NuScale LLC entities from being treated as a “publicly traded partnership” for United States federal income tax purposes. Such restrictions are designed to comply with certain safe harbors provided for under applicable United States federal income tax law. NuScale Corp may also impose additional restrictions on exchanges that it determines to be necessary or advisable so that NuScale LLC is not treated as a “publicly traded partnership” for United States federal income tax purposes. Accordingly, while such position is not free from doubt, NuScale LLC is expected to be operated such that it is not treated as a “publicly traded partnership” taxable as a corporation for United States federal income tax purposes and we intend to take the position that NuScale LLC is so treated as a result of exchanges of its interests pursuant to the A&R NuScale LLC Agreement.

Pursuant to the Tax Receivable Agreement, NuScale Corp will be required to pay to certain Legacy NuScale Equityholders 85% of certain tax benefits, if any, that it realizes (or in certain cases is deemed to realize) as a result of any increases in tax basis and related tax benefits resulting from any exchange of NuScale LLC Class B Units for shares of Class A Common Stock or cash in the future, and those payments may be substantial.

The Legacy NuScale Equityholders may in the future exchange their NuScale LLC Class B Units for Class A Common Stock (or, upon the election of NuScale Corp, cash in an amount equal to the net proceeds raised by selling such Class A Common Stock in a contemporaneous underwritten offering), subject to certain restrictions. Such transactions are expected to result in increases in NuScale Corp’s share of the tax basis of the tangible and intangible assets of NuScale LLC. These increases in tax basis may result in increased tax depreciation and amortization deductions and therefore reduce the amount of income or franchise tax that NuScale Corp would otherwise be required to pay in the future had such sales and exchanges never occurred.

NuScale Corp is party to the Tax Receivable Agreement with NuScale LLC, each of the TRA Holders (as defined in the Tax Receivable Agreement) party thereto and Fluor, in its capacity as TRA Representative (as defined in the Tax Receivable Agreement). Pursuant to the Tax Receivable Agreement, NuScale Corp will be required to pay 85% of the net cash tax savings from certain tax benefits, if any, that it realizes (or in certain cases is deemed to realize) as a result of any increases in tax basis and other tax benefits resulting from any exchange by the TRA Holders of NuScale LLC Class B Units for shares of Class A Common Stock or cash in the future. Any such payments to TRA Holders will reduce the cash provided by the tax savings generated from future exchanges that would otherwise have been available to NuScale Corp for other uses, including reinvestment or dividends to Class A stockholders. Cash tax savings from the remaining 15% of the tax benefits will be retained by NuScale Corp. NuScale Corp’s obligations under the Tax Receivable Agreement accelerate upon a change in control and certain other termination events, as defined therein. These payments are the obligation of NuScale Corp and not of NuScale LLC. The actual increase in NuScale Corp’s allocable share of NuScale LLC’s tax basis in its assets, as well as the amount and timing of any payments under the Tax Receivable Agreement, will vary depending upon a number of factors, including the timing of exchanges, the market price of the Class A Common Stock at the time of the exchange, the extent to which such exchanges are taxable and the amount and timing of the recognition of NuScale Corp’s income. While many of the factors that will determine the amount of payments that NuScale Corp will make under the Tax Receivable Agreement are outside of its control, NuScale Corp expects that the payments it will make

TABLE OF CONTENTS

under the Tax Receivable Agreement will be substantial and could have a material adverse effect on NuScale Corp’s financial condition. Any payments made by NuScale Corp under the Tax Receivable Agreement will generally reduce the amount of overall cash flow that might have otherwise been available to NuScale Corp. To the extent that NuScale Corp is unable to make timely payments under the Tax Receivable Agreement for any reason, the unpaid amounts will be deferred and will accrue interest until paid; however, nonpayment for a specified period may constitute a material breach of a material obligation under the Tax Receivable Agreement and therefore accelerate payments due under the Tax Receivable Agreement, as further described below. Furthermore, NuScale Corp’s future obligation to make payments under the Tax Receivable Agreement could make it a less attractive target for an acquisition, particularly in the case of an acquirer that cannot use some or all of the tax benefits that may be deemed realized under the Tax Receivable Agreement. See the section entitled “Certain Relationship and Related Person Transactions — Tax Receivable Agreement.”

In certain cases, payments under the Tax Receivable Agreement may exceed the actual tax benefits NuScale Corp realizes.

Payments under the Tax Receivable Agreement will be based on the tax reporting positions that NuScale Corp determines, and the U.S. Internal Revenue Service (“IRS”) or another taxing authority may challenge all or any part of the tax basis increases, as well as other tax positions that NuScale Corp takes, and a court may sustain such a challenge. In the event that any tax benefits initially claimed by NuScale Corp are disallowed, the Legacy NuScale Equityholders will not be required to reimburse NuScale Corp for any excess payments that may previously have been made under the Tax Receivable Agreement, for example, due to adjustments resulting from examinations by taxing authorities. Rather, excess payments made to such holders will be netted against any future cash payments otherwise required to be made by NuScale Corp under the Tax Receivable Agreement, if any, after the determination of such excess. However, a challenge to any tax benefits initially claimed by NuScale Corp may not arise for a number of years following the initial time of such payment or, even if challenged early, such excess cash payment may be greater than the amount of future cash payments that NuScale Corp might otherwise be required to make under the terms of the Tax Receivable Agreement and, as a result, there might not be future cash payments against which to net. As a result, in certain circumstances NuScale Corp could make payments under the Tax Receivable Agreement in excess of NuScale Corp’s actual income tax savings, which could materially impair NuScale Corp’s financial condition.

Moreover, the Tax Receivable Agreement provides that, in certain events, including a change of control, breach of a material obligation under the Tax Receivable Agreement, or NuScale Corp exercise of early termination rights, NuScale Corp obligations under the Tax Receivable Agreement will accelerate and NuScale Corp will be required to make a lump-sum cash payment to the Legacy NuScale Equityholders party to the Tax Receivable Agreement equal to the present value of all forecasted future payments that would have otherwise been made under the Tax Receivable Agreement, which lump-sum payment would be based on certain assumptions, including those relating to NuScale Corp future taxable income. The lump-sum payment could be substantial and could exceed the actual tax benefits that NuScale Corp realizes subsequent to such payment because such payment would be calculated assuming, among other things, that NuScale Corp would have certain tax benefits available to it and that NuScale Corp would be able to use the potential tax benefits in future years.

There may be a material negative effect on NuScale Corp’s liquidity if the payments required to be made by NuScale Corp under the Tax Receivable Agreement exceed the actual income or franchise tax savings that NuScale Corp realizes. Furthermore, NuScale Corp’s obligations to make payments under the Tax Receivable Agreement could also have the effect of delaying, deferring or preventing certain mergers, asset sales, other forms of business combinations or other changes of control.

NuScale Corp is a “controlled company” within the meaning of NYSE rules and, as a result, qualifies for exemptions from certain corporate governance requirements. The stockholders of NuScale Corp do not have the same protections afforded to stockholders of companies that are subject to such requirements.

Fluor owns a majority of the voting power of our Common Stock. As a result, we are a “controlled company” under the NYSE rules. As a controlled company, we are exempt from certain corporate governance

TABLE OF CONTENTS

requirements, including those that would otherwise require our Board to have a majority of independent directors and require that we either establish compensation and nominating and corporate governance committees, each comprised entirely of independent directors, or otherwise ensure that the compensation of our executive officers and nominees of directors are determined or recommended to our board of directors by independent members of our board of directors. To the extent we rely on one or more of these exemptions, our stockholders will not have the same protections afforded to stockholders of companies that are subject to all of the NYSE corporate governance requirements.

We are an EGC within the meaning of the Securities Act, and if we take advantage of certain exemptions from disclosure requirements available to “emerging growth companies,” this could make our securities less attractive to investors and may make it more difficult to compare our performance with other public companies.

We are an EGC within the meaning of the Securities Act, as modified by the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not EGCs including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. As a result, our shareholders may not have access to certain information they may deem important. We could be an EGC until December 31, 2025, although circumstances could cause us to lose that status earlier, including if the market value of Common Stock held by non-affiliates exceeds $700,000,000 as of any June 30 before that time, in which case we would no longer be an EGC as of the following December 31. We cannot predict whether investors will find our securities less attractive because we will rely on these exemptions. If some investors find our securities less attractive as a result of our reliance on these exemptions, the trading prices of our securities may be lower than they otherwise would be, there may be a less active trading market for our securities and the trading prices of our securities may be more volatile.

Further, Section 102(b)(1) of the JOBS Act exempts EGCs from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-EGCs but any such election to opt out is irrevocable. We intend to take advantage of the benefits of this extended transition period.

Prior to the closing of the Transactions, Spring Valley’s management was responsible for establishing and maintaining adequate internal control over financial reporting designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. Spring Valley’s management was likewise required, on a quarterly basis, to evaluate the effectiveness of our internal controls and to disclose any changes and material weaknesses identified through such evaluation in those internal controls. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

As described in the Amendment No. 1 to the Annual Report Form on 10-K filed with the SEC on May 7, 2021, Spring Valley identified a material weakness in Spring Valley’s internal control over financial reporting related to the accounting for a significant transaction related to the warrants we issued in connection with our initial public offering in November 2020. As a result of this material weakness, Spring Valley’s management concluded that our internal control over financial reporting was not effective as of December 31, 2020. This material weakness resulted in a material misstatement of our warrant liabilities, change in fair value of warrant liabilities, additional paid-in capital, accumulated deficit and related financial disclosures as of and for the period from August 20, 2020 (inception) through December 31, 2020.

TABLE OF CONTENTS

Spring Valley’s management and its audit committee also concluded that it was appropriate to restate previously issued financial statements for the affected periods.

As described in Amendment No. 2 to the Annual Report on Form 10-K filed with the SEC on December 21, 2021, Spring Valley identified a material weakness in Spring Valley’s internal control over financial reporting related to the Company’s application of ASC 480-10-S99-3A to its accounting classification of the shares held by Public Shareholders and the calculation of earnings per share. As a result of this material weakness, Spring Valley’s management concluded that Spring Valley’s internal control over financial reporting was not effective as of December 31, 2020. Historically, a portion of Spring Valley Class A ordinary shares subject to possible redemption was classified as permanent equity to maintain shareholders’ equity greater than $5 million on the basis that Spring Valley would not redeem its Class A ordinary shares in an amount that would cause its net tangible assets to be less than $5,000,001, as described in the charter. Pursuant to Spring Valley’s re-evaluation of Spring Valley’s application of ASC 480-10-S99-3A to its accounting classification of its Class A ordinary shares subject to possible redemption, Spring Valley’s management determined that the Class A ordinary shares include certain provisions that require classification of all of the Class A ordinary shares as temporary equity regardless of the net tangible assets redemption limitation contained in the charter.

To respond to these material weaknesses, Spring Valley devoted, and NuScale plans to continue to devote, significant effort and resources to the remediation and improvement of our internal control over financial reporting. While we have processes to identify and appropriately apply applicable accounting requirements, we plan to enhance these processes to better evaluate our research and understanding of the nuances of the complex accounting standards that apply to our financial statements. Our plans at this time include providing enhanced access to accounting literature, research materials and documents and increased communication among our personnel and third-party professionals with whom we consult regarding complex accounting applications. The elements of the remediation plan can only be accomplished over time, and we can offer no assurance that these initiatives will ultimately have the intended effects.

Any failure to maintain such internal control could adversely impact our ability to report NuScale’s financial position and results from operations on a timely and accurate basis. If our financial statements are not accurate, investors may not have a complete understanding of our operations. Likewise, if our financial statements are not filed on a timely basis, we could be subject to sanctions or investigations by the NYSE, the SEC or other regulatory authorities. In either case, there could result a material adverse effect on our business. Failure to timely file will cause us to be ineligible to utilize short form registration statements on Form S-3 or Form S-4, which may impair our ability to obtain capital in a timely fashion to execute our business strategies or issue shares to effect an acquisition. Ineffective internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our securities.

We can give no assurance that the measures Spring Valley has taken and that NuScale plans to take in the future will remediate the material weaknesses identified or that any additional material weaknesses or restatements of financial results will not arise in the future due to a failure to implement and maintain adequate internal control over financial reporting or circumvention of these controls. In addition, even if NuScale is successful in strengthening its controls and procedures, in the future those controls and procedures may not be adequate to prevent or identify irregularities or errors or to facilitate the fair presentation of our financial statements.

Risks Related to NuScale’s Business and Industry

These risk factors are not exhaustive, and investors are encouraged to perform their own investigation with respect to the business, financial condition, and prospects of NuScale LLC and its business, financial condition, and prospects. You should carefully consider the following risk factors in addition to the other information included in this prospectus, including matters addressed in the section titled “Cautionary Statement Regarding Forward-Looking Statements.” NuScale may face additional risks and uncertainties that are not presently known to it, or that it currently deems immaterial, which may also impair NuScale business or financial condition. The following discussion should be read in conjunction with the financial statements of NuScale LLC and notes to the financial statements included herein.

Commercialization Risk Factors

We have not yet commercialized or sold NPMs, and a number of factors could prevent, delay or hinder commercialization.

We have not yet entered into a binding contract with a customer to deliver NPMs, and there is no guarantee that we will be able to do so.

The planned initial deployment of our NPM is subject to NuScale LLC reaching a binding agreement for its scope of supply with Utah Associated Municipal Power Systems (“UAMPS”) and UAMPS reaching a binding engineering, procurement, and construction (“EPC”) contract with Fluor. If NuScale LLC and Fluor do not enter into binding agreements with UAMPS, deployment of our NPM, power plants, and ongoing services could be significantly delayed, which could have a material adverse effect on our business and financial condition. Memoranda of understanding we have entered into with other potential purchasers are contingent, and may not result in binding agreements for the purchase of our products or services.

Competitors in China and Russia currently operate commercial SMRs, and may have advantages in marketing their SMRs to potential customers.

Competitors in Russia and China, such as Rosatom and China National Nuclear Corporation, currently operate commercial SMRs in those countries. Although their SMR designs have not been approved by the NRC or in any jurisdiction outside of their native countries, those competitors may have a competitive advantage if they are able to obtain approval comparable to Standard Design Approval (“SDA”), or if they can otherwise demonstrate to potential customers the value and benefits of their SMRs, particularly in jurisdictions that have less stringent regulatory requirements. In addition, these competitors may have access to greater government or other funding to develop and commercialize their SMRs than we do.

We may be unable to charge UAMPS, our first customer, for some costs we have incurred and we may be required to reimburse UAMPS if we fail to achieve specified performance measures.

We entered into a Cost Sharing Option Agreement and a Subaward Agreement in 2015 (collectively, the “CSO and Subaward Agreements”) that facilitate sharing a DOE award with UAMPS for early siting and licensing for the Carbon Free Power Project (“CFPP”). Under those agreements, the DOE has been paying half of the costs and UAMPS and NuScale LLC have shared the other half. We have incurred reimbursable costs of $4.1 million under the CSO and Subaward Agreements. If UAMPS determines to file a license application with the NRC for the CFPP, UAMPS must then pay us for those costs; however, if UAMPS, or its wholly-owned subsidiary, CFPP LLC, does not file a license application, we will be unable to bill those costs to UAMPS.

In conjunction with certain agreements related to the CFPP awarded to Fluor, pursuant to which we are developing the NRC license application for the CFPP and performing other site licensing and development activities, we entered into a Development Cost Reimbursement Agreement with UAMPS (the “DCRA”).

Under the DCRA, we may be obligated to refund to UAMPS a percentage of its net development costs up to a specified cap, which vary based on the stage of project development, if (1) at specified times in the development of the CFPP, the estimated cost of electricity (based on increasingly accurate project cost

TABLE OF CONTENTS

estimates at various stages of development) exceeds an agreed target cost of $58.00/megawatt-hour (subject to adjustment as specified in the DCRA), or if Fluor does not timely provide a required comparison (which we refer to as an economic competitive test, or “ECT”), (2) the NRC does not issue design certification for the NuScale design by March 31, 2023, (3) the NRC does not issue SDA for the NuScale design within one year after the NRC’s published date for such approval after acceptance of the SDA application, or (4) NuScale LLC materially breaches the DCRA and the DCRA is terminated for cause. The reimbursement percentage and cap is 100% and $57 million until UAMPS or CFPP LLC submit a combined construction and operating license for approval to the NRC (“COLA”). After the COLA is submitted, the reimbursement percentage is 20% and (a) the cap for an ECT failure before final notice to proceed with NuScale plant construction is $60 million and (b) the cap for termination of the DCRA for cause is $120 million through delivery of a “Class 2” project cost estimate (an estimate that is accurate within -15% to +20%) and thereafter $180 million through the final notice to proceed, which requires a “Class 1” project cost estimate (an estimate that is accurate within -10% to +15%).

Any delays in the development and manufacture of NPMs and related technology may adversely impact our business and financial condition.

We have previously experienced, and may experience in the future, delays or other complications in the design, manufacture, production and delivery of NPMs and related technology that could prevent us from delivering NPMs in 2027 or beyond. If delays like this recur, if our remediation measures and process changes do not continue to be successful, if we fail to find a satisfactory manufacturer or if we experience issues with planned manufacturing activities or design and safety, we could experience issues or delays in sustaining or further increasing production and sales of NPMs.

If we encounter difficulties in scaling our production and delivery capabilities, if we fail to develop and successfully commercialize our NPMs and related technologies, if we fail to develop such technologies before our competitors or if such technologies fail to perform as expected, are inferior to those of our competitors or are perceived as less safe than those of our competitors, our business and financial condition could be materially and adversely impacted.

We have not yet delivered NPMs to customers, and any setbacks we may experience during our first commercial delivery planned for 2028 and other demonstration and commercial missions could have a material adverse effect on our business, financial condition and results of operation, and could harm our reputation.

The success of our business will depend on our ability to successfully deliver NPMs to customers on-time and on-budget at guaranteed performance levels, which would tend to establish greater confidence in our subsequent customers. There is no guarantee that our planned NPM deployments will be successful. There can be no assurance that we will not experience operational or process failures and other problems during our first commercial deployment or any planned deployment thereafter. Any failures or setbacks, particularly on our first commercial deployments, could harm our reputation and have a material adverse effect on our business and financial condition.

Any actual or perceived safety or reliability issues may result in significant reputational harm to our businesses, in addition to tort liability and other costs that may arise. Such issues could result in delaying or cancelling planned deployments of NPMs, increased regulation, or other systemic consequences. Our inability to meet our safety standards or adverse publicity affecting our reputation as a result of accidents or mechanical failures could have a material adverse effect on our business and financial condition.

We have incurred significant losses since inception, we expect to incur losses in the future, and we may not be able to achieve or maintain profitability.

We have incurred significant losses since our inception well beyond the support we have received through cost-sharing awards from the DOE. We have not yet delivered NPMs or VOYGR plants to customers, and it is difficult for us to predict our future operating results. As a result, our losses may be larger than anticipated, and we may not achieve profitability when expected or at all; even if we do, we may not be able to maintain or increase profitability.

TABLE OF CONTENTS

We expect our operating expenses to increase over the next several years as we commence deployment of NPMs, continue to refine and streamline our design and manufacturing processes for our NPMs, make technical improvements, hire additional employees and continue research and development efforts relating to new products and technologies. These efforts may be more costly than we expect and may not result in increased revenue, profits or growth in our business. Any failure to increase our revenue sufficiently to keep pace with our expenses could prevent us from achieving or maintaining profitability or positive cash flow. Furthermore, if our future growth and operating performance fail to meet investor or analyst expectations, or if we have future negative cash flow or losses resulting from our investment in acquiring customers or expanding our operations, this could have a material adverse effect on our business and financial condition.

The cost of electricity generated from nuclear sources may not be cost competitive with other electricity generation sources in some markets, which could materially and adversely affect our business.

Some electricity markets experience very low power prices due to a combination of subsidized renewables and low-cost fuel sources, and NuScale LLC may not be able to compete in these markets unless the benefits of the carbon-free, reliable and/or resilient energy generation provided by our NPMs are sufficiently valued in the market. Given the relatively lower electricity prices in the United States when compared to many international markets, the risk may be greater with respect to business in the United States. Moreover, historically very low (or negative) market prices are the result of surplus generation that cannot be curtailed and are transitory. These low prices do not reflect a price to beat for NuScale’s technology.

The market for SMRs generating nuclear power is not yet established and may not achieve the growth potential we expect or may grow more slowly than expected.

The market for SMRs has not yet been established. Our estimates for the total addressable market are based on a number of internal and third-party estimates, including our potential contracted revenue, the number of potential customers who have expressed interest in our NPMs, assumed prices and production costs for our NPMs, our ability to leverage our current logistical and operational processes, and general market conditions. However, our assumptions and the data underlying our estimates may not be correct and the conditions supporting our assumptions or estimates may change at any time, thereby reducing the predictive accuracy of these underlying factors. As a result, our estimates of the annual total addressable market for our services, as well as the expected growth rate for the total addressable market for our services, may prove to be incorrect.

Our commercialization strategy relies heavily on our relationship with Fluor and other strategic investors and partners, who may have interests that diverge from ours and who may not be easily replaced if our relationships terminate.

We rely heavily upon our relationship with Fluor, our majority owner, and our relationships with other of our investors and strategic partners to commercialize our NPM and our other products and services. We granted Fluor certain rights to provide engineering, procurement and construction services in connection with NuScale LLC’s general plant design, project-specific designs and services typically performed by Fluor or its direct competitors. Similarly, we have entered into certain agreements with Doosan Heavy Industries and Construction Company, Ltd. (“Doosan”), IHI Corporation (“IHI”), and Sarens Nuclear & Industrial Services, LLC (“Sarens”) for certain planning, engineering, manufacturing and support activities, and JGC Holdings Corporation (“JGC”), an affiliate of Japan NuScale LLC Innovation, LLC, related to the EPC and commissioning of the first NuScale LLC plant in the United States and in other specific geographic areas, and with Samsung C&T Corporation (“Samsung C&T”) related to certain EPC activities.

Our strategic partners may have interests that diverge from our interests, and which may hinder our ability to negotiate sales to customers. If we lose our agreements with strategic partners, we may need to find new contractors who may have less experience designing and building nuclear plants. This could substantially hinder our ability to expand our production capacity and installation of VOYGR plants, and could affect our business and our prospects.

We may be unable to manage our future growth effectively, which could make it difficult to execute our business strategy.

If our operations grow as planned, we may need to expand our sales and marketing, research and development, supply and manufacturing functions, and there is no guarantee that we will be able to scale

TABLE OF CONTENTS

the business and the manufacture of NPMs as planned, as there is no guarantee that we will be able to find suitable locations or partners for the expanded manufacture and operation of our NPMs or to broaden our internal capabilities.

Any failure to effectively incorporate updates to the design, construction, and operations of NuScale LLC plants to ensure cost competitiveness could reduce the marketability of the NuScale LLC design and has the potential to impact deployment schedules.

Updating the design, construction, and operations of NuScale LLC plants will be necessary to their competitiveness and attractiveness in the market, particularly in the United States where the price of power is generally lower. If we are not able to achieve and maintain cost-competitiveness in the United States or elsewhere, our business could be materially and adversely affected.

Our NPM design will be actively managed through design reviews, prototyping, involvement of external partners and application of industry lessons, but we could still fail to identify latent manufacturing and construction issues early enough to avoid negative effects on production, fabrication, construction or ultimate performance of our NPMs or plants. Where these issues arise at such later stages of deployment, plant deployment could be subject to greater costs or be significantly delayed, which could materially and adversely affect our business.

We and our customers operate in a politically sensitive environment, and the public perception of nuclear energy can affect our customers and us.

The risks associated with radioactive materials and the public perception of those risks can affect our business. Opposition by third parties can delay or prevent the construction of new nuclear power plants and can limit the operation of nuclear reactors. Adverse public reaction to developments in the use of nuclear power could directly affect our customers and indirectly affect our business. In the past, adverse public reaction, increased regulatory scrutiny and litigation have contributed to extended construction periods for new nuclear reactors, sometimes delaying construction schedules by decades or more or even shutting down operations. In addition, anti-nuclear groups in Germany successfully lobbied for the adoption of the Nuclear Exit Law in 2002, which requires the shutdown of all German nuclear power plants by 2022. Adverse public reaction could also lead to increased regulation or limitations on the activities of our customers, more onerous operating requirements or other conditions that could have a material adverse impact on our customers and our business.

Accidents involving nuclear power facilities, including but not limited to events similar to the Three Mile Island, Chernobyl and Fukushima Daiichi nuclear accidents, or terrorist acts or other high profile events involving radioactive materials could materially and adversely affect our customers and the markets in which we operate and increase regulatory requirements and costs that could materially and adversely affect our business.

Our future prospects are dependent upon a certain level of public support for nuclear power. Nuclear power faces strong opposition from certain competitive energy sources, individuals and organizations. The accident that occurred at the Fukushima nuclear power plant in Japan in 2011 increased public opposition to nuclear power in some countries, resulting in a slowdown in, or, in some cases, a complete halt to new construction of nuclear power plants, an early shut down of existing power plants or a dampening of the favorable regulatory climate needed to introduce new nuclear technologies all could negatively impact our business and prospects. As a result of the Fukushima accident, some countries that were considering launching new domestic nuclear power programs delayed or cancelled the preparatory activities they were planning to undertake as part of such programs. If accidents similar to the Fukushima disaster or other events, such as terrorist attacks involving nuclear facilities, occur, public opposition to nuclear power may increase, regulatory requirements and costs could become more onerous and customer demand for our NPMs could suffer, which could materially and adversely affect our business and operations.

TABLE OF CONTENTS

Our supply base may not be able to scale to the production levels necessary to meet sales projections.

NuScale LLC does not have manufacturing assets and relies on third party manufacturers to build our NPMs and associated equipment. Moreover, we are dependent on future supplier capability to meet production demands attendant to our forecasts. If our supply chain cannot meet the schedule demands of the market, our projected sales revenues could be materially impacted.

Lack of availability and cost of component raw materials may affect the manufacturing processes for plant equipment and increase our costs.

Recent global supply chain disruptions have increasingly affected both the availability and cost of raw materials, component manufacturing and deliveries. These disruptions may result in delays in equipment deliveries and cost escalations that could adversely affect our business.

We are highly dependent on our senior management team and other highly skilled personnel, and if we are not successful in attracting or retaining highly qualified personnel, we may not be able to successfully implement our business strategy.

Our success depends, in significant part, on the continued services of our senior management team and on our ability to attract, motivate, develop and retain a sufficient number of other highly skilled personnel, including engineers, manufacturing and quality assurance, finance, marketing and sales personnel. Our senior management team has extensive experience in the energy and manufacturing industries, and we believe that their depth of experience is instrumental to our continued success. The loss of any one or more members of our senior management team, for any reason, including resignation or retirement, could impair our ability to execute our business strategy and have a material adverse effect on our business and financial condition if we are unable to successfully attract and retain qualified and highly skilled replacement personnel.

We may require additional future funding.

To date, we have not generated any material revenue, while we have substantial overhead expenses. We do not expect to generate meaningful revenue unless and until we are able to finalize development of and commercialize our SMR technology and related services, and we may not be able to do so on our anticipated timetable, if at all. We expect our expenses and capital expenditures to increase in connection with our ongoing activities, including developing and advancing our SMR and other products and services, obtaining NRC design certification of and SDA for our SMR and completing our manufacturing preparation and trials. We also expect to incur additional costs associated with operating as a public company. Certain costs are not reasonably estimable at this time and we may require additional funding and our projections anticipate certain customer-sourced income that is not guaranteed.

Our outstanding NuScale Corp Warrants would likely only be exercised if the trading price of our Class A Common Stock exceeds the $11.50 per share exercise price of the warrants. The high trading price of our shares of Class A Common Stock between the Closing Date and June 9, 2022 was $10.80. Our stock trading price may not exceed $11.50 before May 2, 2027, when the NuScale Corp Warrants expire, and therefore we may not receive any proceeds from the exercise of warrants to fund our operations. In addition, in certain circumstances, the NuScale Corp Warrants can be exercised on a cashless basis. See “Description of Capital Stock — Warrants.”

We may seek to raise capital through private or public equity or debt financings or through other sources of financing. Adequate additional funding may not be available to us on acceptable terms or at all. Our ability to raise funds through equity offerings may be limited by the significant number of shares that may be publicly sold, including the shares registered for resale under this registration statement. Such sales may negatively affect the market price of our Class A Common Stock. In particular, a large sale by Fluor, our majority shareholder and an important strategic partner, could significantly affect our stock price.

Our failure to raise capital as and when needed could have a negative impact on our financial condition and our ability to pursue our business strategies. If we raise additional funds by issuing equity securities, our stockholders will experience dilution. If we raise additional capital through debt financing, we may be subject to covenants that restrict our operations including limitations on our ability to incur liens or

TABLE OF CONTENTS

additional debt, pay dividends, repurchase our securities, make certain investments, and engage in certain merger, consolidation or asset sale transactions. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders and members. If the needed financing is not available, or if the terms of financing are less desirable than we expect, we may be required to delay, scale back or terminate some or all of our research and development programs.

Our funding plan relies on cost-shared funding provided through a cooperative agreement with the DOE. Significant funding has been received from the DOE under four separate cost-share awards granted since 2013. As of December 31, 2021, the DOE has obligated $170.5 million to the current program. The overall DOE contribution to NuScale LLC commercialization funding is more than $425 million. The current DOE award is a $700 million award ($350 million in government funding to be matched by $350 million in private funding). Funding is subject to at least annual Congressional appropriations, which may not be forthcoming. The fiscal year 2023 Congressional Budget Justification prepared by the DOE in connection with President Biden’s budget proposal to Congress, recites that approximately $40 million is requested for advanced SMR research and development, but no amounts are specified for the CFPP or U.S. domestic SMR demonstrations. The federal budget process is complex — the budget justification and Presidential budget requests are incomplete; Congress may appropriate different amounts than those requested; and the DOE has varying degrees of discretion to reprogram or transfer appropriated funds. Nonetheless, to the extent Presidential budget requests or DOE budget justifications result in a shift of Congressional appropriations away from SMR funding generally or projects we are developing specifically, those shifts could materially and adversely affect our business.

If we are unable to continue as a going concern, we may be forced to liquidate our assets and the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our financial statements.

As part of our arrangements with the DOE, we granted the DOE a worldwide, nonexclusive, paid-up license to our intellectual property and to manufacture our SMR technology, and the right to sublicense those rights if specified conditions arise, including if the DOE terminates the award due to material failure to comply with the terms and conditions of the award, or if we fail to meet our cost-sharing obligations or cease developing our SMR. As a result, if we are unable to continue as a going concern, the value of our intellectual property, including in liquidation, may be difficult to assess.

Our ability to protect our patents and other proprietary rights may be challenged and is not guaranteed, exposing us to the possible loss of competitive advantage.

We rely upon a combination of patents, trademarks, copyrights, trade secret, and commercial agreements such as confidentiality agreements, assignment agreements, and license agreements to protect the intellectual property associated with our NPMs and related technologies. These measures prevent third parties from using, practicing, selling, manufacturing, or otherwise commercially exploiting our NPMs and related technologies, which would erode our competitive position in our market. Our success depends in large part on our ability to obtain and enforce patent protection for our NPMs, as well as our ability to operate without infringing on or violating the proprietary rights of others. We own and have licensed rights to patents and pending patent applications, and will continue to file patent applications claiming new technologies directed to NPMs in the United States and in other jurisdictions based on factors such as commercial viability.

As with all industries, the patent position of power modules and nuclear energy companies generally is uncertain and is not a guaranteed right. During the patent procurement process, a patent office may require us or our licensors to narrow the scope of the claims of our or our licensors’ pending and future patent applications. This may limit the scope of patent protection and our or our licensors’ ability to claim patent infringement if the patent application is subsequently issued. In some cases, a patent application may not issue if we or our licensors are unable to overcome rejections from a patent office. If a patent application does not issue, we or our licensors may lose trade secret that is disclosed and published in the patent application and third parties may be able to exploit such published information in our patent application. Additionally, even if we obtain a patent registration in one jurisdiction (e.g., the United States), we cannot guarantee that we will obtain a patent registration for the same or related patent application in another jurisdiction (e.g., China) as patent laws differ from jurisdiction to jurisdiction. Additionally, maintaining and enforcing patent rights can involve complex legal and factual questions and may be subject to litigation in some cases.

TABLE OF CONTENTS

For example, third parties may challenge the validity of our or our licensors’ patents based on prior art at a tribunal such as the Patent Trial and Appeal Board at the United States Patent and Trademark Office and/or in a federal court. Because we cannot assure that all of the potentially relevant prior art relating to our patents and patent applications has been found, third parties may prevail in invalidating a patent or preventing a patent application from being issued as a patent. If we or our licensors are able to maintain valid patents or prevail in patent challenges instituted by third parties, we or our licensors may still bear the risk of third parties “designing around” our technologies to avoid an intellectual property infringement claim.

We enjoy only limited geographical protection with respect to certain patents and may not be able to protect our intellectual property rights throughout the world.

We do not have worldwide patent rights for our NPMs and related technologies because there is no such thing as worldwide or “international patent rights.” Accordingly, we may not be able to protect our intellectual property rights in certain jurisdictions and their legal systems. Filing, prosecuting and defending patents on our NPMs worldwide can pose several challenges. First, procuring patent rights in multiple jurisdictions would be cost prohibitive because individual patent offices in different jurisdictions will have to examine each patent application separately. Therefore, costs such as examination fees, translation fees, and attorney fees are considered. Once a patent is registered, we or our licensors will also have the continued obligation of paying maintenance fees periodically to avoid patents from becoming abandoned or lapsed. Second, the breadth of claims in patents may vary from jurisdiction to jurisdiction. For instance, certain patent offices may require narrower claims, resulting in patent rights that are less extensive. Further, as noted above, we may not be able to obtain patents in some jurisdictions even if we obtain patents in other jurisdictions. Accordingly, our competitors may operate in countries where we do not have patent protection and can freely use our technologies and discoveries in such countries to the extent such technologies and discoveries are publicly known or disclosed in countries where we do have patent protection or pending patent applications.

In addition, many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. Many countries also limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patent. If we or any of our licensors are forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be impaired, and our business and financial condition may be adversely affected.

We may not identify relevant third-party patents or may incorrectly interpret the relevance, scope or expiration of a third-party patent, which might adversely affect our ability to develop and market NPMs.

We cannot guarantee that any of our patent searches or analyses, including the identification of relevant patents, the scope of patent claims or the expiration of relevant patents, are complete or thorough because there may be hundreds of thousands of relevant patents worldwide. We also cannot be certain that we have identified each and every third-party patent and pending application in the United States and abroad that is relevant to or necessary for the commercialization of NPMs in any jurisdiction. The scope of a patent claim is generally determined by an interpretation of the law, the written disclosure in a patent, and the patent’s prosecution history. Our interpretation of the relevance or the scope of a patent or a pending application may be incorrect or not accepted by a court of competent jurisdiction. Our determination of the expiration date of any patent in the United States or abroad that we consider relevant may be incorrect or inaccurate. Our failure to identify and correctly interpret relevant patents may negatively impact our ability to develop and market NPMs.

In addition, there are several circumstances under which a patent application may not be published and accessible to us or our licensors. For example, patent applications in the United States and many foreign jurisdictions are typically not published until 18 months after filing, but some patent applications in the United States may be maintained in secrecy until the patents are issued. Publications in the scientific literature also often lag behind actual discoveries. Therefore, we cannot be certain that others have not filed patent applications for technology covered by our issued patents or our pending applications, or that we were the first to invent the technology. Our competitors may have filed, and may in the future file, patent applications covering NPMs or technology similar to ours without us knowing. Any such patent application may have

TABLE OF CONTENTS

priority over our patent applications or patents, which could require us to procure rights to issued patents covering such technologies in order to avoid infringement claims.

We may be subject to claims of ownership and other rights to our patents and other intellectual property by third parties.

Our confidentiality and intellectual property assignment agreements with our employees, consultants, and contractors generally provide that inventions conceived by the party in the course of rendering services to us will be our exclusive intellectual property. While we require our employees, consultants, and contractors to assign such intellectual property to us in the event that the intellectual property is not automatically assigned (e.g., as work made for hire), those agreements may not be honored and obligations to assign intellectual property may be challenged or breached. Moreover, there may be some circumstances, where we are unable to negotiate for such ownership rights and/or others misappropriate those rights in the process.

We may be subject to claims that former employees, collaborators, or other third parties have an interest in our patents or other intellectual property as an owner, a joint owner, a licensee, an inventor, or a co-inventor. In the latter two cases, the failure to name the proper inventors on a patent application can result in the patents issuing thereon being unenforceable. Inventorship disputes may arise from conflicting views regarding the contributions of different individuals named as inventors, the effects of foreign laws where foreign nationals are involved in the development of the subject matter of the patent, conflicting obligations of third parties involved in developing our power modules or as a result of questions regarding co-ownership of potential joint inventions. Litigation may be necessary to resolve these and other claims challenging inventorship and/or ownership. Alternatively, or additionally, we may enter into agreements to clarify the scope of our rights in such intellectual property. If we fail in defending any such claims, in addition to paying monetary damages, we may lose exclusive ownership of, or right to use or license valuable intellectual property. Such an outcome could have a material adverse effect on our business. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees.

Regulatory Risk Factors

Our SDA application for the 77 MWe power module has not yet been submitted to the NRC, and its approval is not guaranteed.

Increasing the power that can be generated by our NPMs is a key part of our plan, and our higher- capacity, 77 MWe power module is subject to obtaining SDA from the NRC. The need to obtain that approval complicates our licensing process and could affect the planned deployment schedule for our first NPMs. In particular, if the NRC disagrees with our licensing approach or the breadth and/or scope of the design changes proposed, the construction and operating license application process could take longer than currently expected, which could materially and adversely affect our business. Further, we face the risk that the NRC could impose terms in the SDA that are not acceptable to us.

Our design is only approved in the United States and we must obtain approvals on a country-by-country basis before we can sell our products abroad, which approvals may be delayed or denied or which may require modification to our design.

Our SMR design has not been approved in any country except the United States. Each country has its own safety approval that we must obtain before we can sell or install our NPMs abroad. Foreign approval processes may differ materially from the NRC process, and approvals may be denied or delayed in foreign countries, or some countries may require that we alter our design before obtaining approval. Denial or delay in approvals abroad could materially and adversely affect our business.

Our customers must obtain additional regulatory approvals before they construct power plants using our NPMs, and approvals may be denied or delayed.

The lead time to build a nuclear power facility is long, and requires site licensing and approvals from applicable regulatory agencies before a plant can be constructed. The regulatory framework to obtain

TABLE OF CONTENTS

approvals is complex, and varies from country to country. Any delays experienced by our customers in siting a power plant using our products and services could materially and adversely affect our business.

Our customers could incur substantial costs as a result of violations of, or liabilities under, environmental laws.

The operations and properties of our customers are subject to a variety of federal, state, local and foreign environmental, health and safety laws and regulations governing, among other things, air emissions, wastewater discharges, management and disposal of hazardous, non-hazardous and radioactive materials and waste and remediation of releases of hazardous materials. Although NuScale LLC’s business is to design and sell technology rather than to construct and own or operate power plants, we must design our technology so it complies with such laws and regulations. Compliance with environmental requirements could require our customers to incur significant expenditures or result in significant restrictions on their operations, and the failure to comply with such laws and regulations, including failing to obtain any necessary permits, could result in substantial fines or enforcement actions, including regulatory or judicial orders enjoining or curtailing operations or requiring our customers to conduct or fund remedial or corrective measures, install pollution control equipment or perform other actions. More vigorous enforcement by regulatory agencies, the future enactment of more stringent laws, regulations or permit requirements, including relating to climate change, or other unanticipated events may arise in the future and adversely impact the market for our products, which could materially and adversely affect our business, financial condition and results of operations.

We are subject to stringent United States export and import control laws and regulations. Unfavorable changes in these laws and regulations or United States government licensing policies, our failure to secure timely United States government authorizations under these laws and regulations, or our failure to comply with these laws and regulations could have a material adverse effect on our business, financial condition and results of operations.

The inability to secure and maintain required export licenses or authorizations could negatively impact our ability to compete successfully or market our SMR technology for commercial applications outside the United States. For example, if we were unable to obtain or maintain our licenses to export certain nuclear hardware, we would be effectively prohibited from exporting our SMR technology in non-United States locations, which would limit the number of customers to those in the United States. In addition, if we were unable to obtain authorization to export our technology, hardware, code or technical assistance, we would experience a limited market for our technology, which would provide a competitive edge to international suppliers of SMRs. In both cases, these restrictions could lead to an adverse impact on our ability to sell our commercial technology. Similarly, if we were unable to secure export authorization, we may need to implement design changes to our NPM to address issues with our domestic supplier chain, which may increase costs or result in delays in delivery of new plants and subsequent additional NPMs when ordered.

Failure to comply with export control laws and regulations could expose us to civil or criminal penalties, fines, investigations, more onerous compliance requirements, loss of export privileges, debarment from government contracts or limitations on our ability to enter into contracts with the United States government. In addition, any changes in export control regulations or United States government licensing policy, such as that necessary to implement United States government commitments to multilateral control regimes, may restrict our operations.

Our business is subject to a wide variety of extensive and evolving government laws and regulations. Changes in and/or failure to comply with such laws and regulations could have a material adverse effect on our business.

Regulatory risk factors associated with our business also include:

•

our ability to obtain additional applicable approvals, licenses or certifications from regulatory agencies, if required, and to maintain current approvals, licenses or certifications;

•

our ability to obtain regulatory approval for a site boundary emergency planning zone defined in such a fashion as will benefit the majority of U.S.-based customers;

•

regulatory delays, delays imposed as a result of regulatory inspections, and changing regulatory requirements, may cause a delay in our ability to fulfill our existing or future orders, or cause planned

TABLE OF CONTENTS

plants to not be completed at all, many of which may be out of our control, including natural disasters, changes in governmental regulations or in the status of our regulatory approvals or applications or other events that force us to cancel or reschedule plant construction, which could have an adverse impact on our business and financial condition;

•

regulatory, availability and other challenges may delay our progress in establishing the number of plant sites we require for our targeted build rate, which could have an adverse effect on our ability to grow our business; and

•

challenges as a result of regulatory processes or in NuScale LLC’s ability to secure the necessary permissions to establish these plant sites could delay our ability to achieve our target build rate and could adversely affect our business.

General Risk Factors

COVID-19 and any future widespread public health crisis could negatively affect various aspects of our business, make it more difficult for us to meet our obligations to our customers, and result in reduced demand for our products and services.

In an effort to halt the outbreak of COVID-19, a number of countries, including the United States, have placed significant restrictions on travel, many businesses have announced extended closures, and many businesses and governmental agencies have allowed employees to work remotely, which in some cases may reduce the effectiveness of those employees. These travel restrictions and business closures may in the future adversely affect our operations locally and worldwide, including our ability to obtain regulatory approvals and to manufacture, market, sell or distribute our products, which could materially and adversely affect our business. We cannot predict the impact that remote work will have on the culture of NuScale LLC and our employee retention.

Many of our customers and suppliers worldwide were affected by COVID-19 and temporarily closed their facilities, which impacted the speed of our customer engagement and research and development. The impact of COVID-19 on NuScale LLC’s operational and financial performance will depend on various future developments, including the duration and spread of the outbreak and impact on regulatory agencies, customers, suppliers and employees, all of which remain uncertain at this time.

Changes in tax laws or regulations may increase tax uncertainty and adversely affect results of our operations and our effective tax rate.

We will be subject to taxes in the United States and certain foreign jurisdictions. Due to economic and political conditions, tax rates in various jurisdictions, including the United States, may be subject to change. Our future effective tax rates could be affected by changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities and changes in tax laws or their interpretation. In addition, we may be subject to income tax audits by various tax jurisdictions. An adverse resolution by one or more taxing authorities could have a material impact on our finances. Further, we may be unable to utilize any net operating losses in the event a change in control is determined to have occurred.

We may become involved in litigation that may materially adversely affect us.

From time to time, we may become involved in various legal proceedings relating to matters incidental to the ordinary course of our business, including intellectual property, commercial, product liability, employment, class action, whistleblower and other litigation and claims, and governmental and other regulatory investigations and proceedings. Such matters can be time-consuming, divert management’s attention and resources from the operation of our business and cause us to incur significant expenses or liability or require us to change our business practices. Because of the potential risks, expenses and uncertainties of litigation, we may, from time to time, settle disputes, even where we believe that we have meritorious claims or defenses. Because litigation is inherently unpredictable, we cannot assure you that the results of any of these actions will not have a material adverse effect on our business.

Risks Related to this Offering and Ownership of Our Shares of Class A Common Stock or NuScale Corp Warrants

Our Organizational Documents designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for substantially all disputes between NuScale Corp and its stockholders.

Our Organizational Documents provide that the Court of Chancery of the State of Delaware or, if such court does not have subject matter jurisdiction thereof, another state or federal court located within the State of Delaware, shall be the exclusive forum for certain actions and claims. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with NuScale Corp or any of NuScale Corp’s directors, officers, or other employees, which may discourage lawsuits with respect to such claims. However, stockholders will not be deemed to have waived NuScale Corp’s compliance with the federal securities laws and the rules and regulations thereunder and this provision would not apply to suits brought to enforce a duty or liability created by the Exchange Act, which provides for the exclusive jurisdiction of the federal courts with respect to all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder, or the Securities Act. Further, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. Accordingly, both state and federal courts have jurisdiction to entertain such claims. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, the Organizational Documents provide that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. Accordingly, there is uncertainty as to whether a court would enforce such provision with respect to suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. If a court were to find the choice of forum provision contained in the Organizational Documents to be inapplicable or unenforceable in an action, NuScale Corp may incur additional costs associated with resolving such action in other jurisdictions, which could harm NuScale Corp’s business, results of operations and financial condition.

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

Our warrant agreement provides that, subject to applicable law, (i) any action, proceeding or claim against us arising out of or relating in any way to the warrant agreement, including under the Securities Act, will be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and (ii) that we irrevocably submit to such jurisdiction, which jurisdiction shall be the exclusive forum for any such action, proceeding or claim. We will waive any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum.

Notwithstanding the foregoing, these provisions of the warrant agreement will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal district courts of the United States of America are the sole and exclusive forum. Any person or entity purchasing or otherwise acquiring any interest in any of our warrants shall be deemed to have notice of and to have consented to the forum provisions in our warrant agreement. If any action, the subject matter of which is within the scope of the forum provisions of the warrant agreement, is filed in a court other than a court of the State of New York or the United States District Court for the Southern District of New York (a “foreign action”) in the name of any holder of our warrants, such holder shall be deemed to have consented to: (x) the personal jurisdiction of the state and federal courts located in the State of New York in connection with any action brought in any such court to enforce the forum provisions (an “enforcement action”), and (y) having service of process made upon such warrant holder in any such enforcement action by service upon such warrant holder’s counsel in the foreign action as agent for such warrant holder.

This choice-of-forum provision may limit a warrant holder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with our company, which may discourage such lawsuits. Alternatively, if a court were to find this provision of our warrant agreement inapplicable or unenforceable with respect to

TABLE OF CONTENTS

one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could materially and adversely affect our business, financial condition and results of operations and result in a diversion of the time and resources of our management and Board.

The NuScale Corp Warrants are expected to be accounted for as liabilities and the changes in value of the NuScale Corp Warrants could have a material effect on our financial results.

The NuScale Corp Warrants are currently classified as liabilities. Under this accounting treatment, we are required to measure the fair value of the NuScale Corp Warrants at the end of each reporting period and recognize changes in the fair value from the prior period in our operating results for the current period. As a result of the recurring fair value measurement, our financial statements and results of operations may fluctuate quarterly based on factors which are outside our control. We expect that we will recognize non-cash gains or losses due to the quarterly fair valuation of the NuScale Corp Warrants and that such gains or losses could be material.

The unaudited pro forma financial information included elsewhere in this prospectus may not be indicative of what NuScale Corp’s actual financial position or results of operations would have been.

The pro forma financial information included in this prospectus is presented for informational purposes only and is not necessarily indicative of the financial position or results of operations that would have actually occurred had the Transactions been completed at or as of the dates indicated, nor is it indicative of the future operating results or financial position of NuScale. The pro forma statement of operations does not reflect future nonrecurring charges resulting from the Transactions. The unaudited pro forma financial information does not reflect future events that may occur after the Transactions and does not consider potential impacts of future market conditions on revenues or expenses. The pro forma financial information included in the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” has been derived from Spring Valley’s and NuScale LLC’s historical financial statements and certain adjustments and assumptions have been made regarding NuScale LLC after giving effect to the Transactions. There may be differences between preliminary estimates in the pro forma financial information and the final acquisition accounting, which could result in material differences from the pro forma information presented in this prospectus in respect of the estimated financial position and results of operations of NuScale LLC.

In addition, the assumptions used in preparing the pro forma financial information may not prove to be accurate and other factors may affect NuScale LLC’s financial condition or results of operations following the Closing. Any potential decline in NuScale LLC’s financial condition or results of operations may cause significant variations in the stock price of NuScale Corp.

The price of Class A Common Stock and NuScale Corp Warrants may be volatile.

The price of Class A Common Stock and NuScale Corp Warrants may fluctuate due to a variety of factors, including:

•

changes in the industries in which NuScale Corp and its customers operate;

•

variations in its operating performance and the performance of its competitors in general;

•

material and adverse impacts of the COVID-19 pandemic on the markets and the broader global economy;

•

actual or anticipated fluctuations in NuScale Corp’s quarterly or annual operating results;

•

the public’s reaction to NuScale Corp’s press releases, its other public announcements and its filings with the SEC;

•

NuScale Corp’s failure or the failure of its competitors to meet analysts’ projections or guidance that NuScale Corp or its competitors may give to the market;

•

additions and departures of key personnel;

TABLE OF CONTENTS

•

changes in laws and regulations affecting its business;

•

commencement of, or involvement in, litigation involving NuScale Corp;

•

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

•

publication of research reports by securities analysts about NuScale Corp, its competitors or its industry;

•

sales of shares of Class A Common Stock by the PIPE Investors; and

•

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

These market and industry factors may materially reduce the market price of Class A Common Stock and NuScale Corp Warrants regardless of the operating performance of NuScale Corp.

Sales of a substantial number of shares of Class A Common Stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of Class A Common Stock. These risks could be increased if the sale or potential sales involves Fluor our majority shareholder and an important strategic partner.

As of June 9, 2022, there were (i) 43,615,304 shares of Class A Common Stock outstanding, (ii) 178,396,711 shares of Class A Common Stock issuable upon the exchange of NuScale LLC Class B Units (together with cancellation of an equal number of shares of NuScale Corp Class B Common Stock) pursuant to the procedures set forth in the A&R NuScale LLC Agreement, and (iii) 35,199,894 shares of Class A Common Stock issuable upon the exercise of outstanding stock options and warrants.

Although the Sponsor and certain of the Legacy NuScale Equityholders are subject to certain restrictions regarding the transfer of Class A Common Stock, these shares may be sold after the expiration or early termination of the respective applicable lock-ups under the Sponsor Letter Agreement. The registration statements of which this prospectus forms a part provides for the potential resale of 209,870,307 shares of Class A Common Stock. We also intend to file a registration statement on Form S-8 to register the shares of Class A Common Stock issuable upon exercise of options and other equity awards under the NuScale LLC 2011 Equity Incentive Plan and the NuScale Corp 2022 Long-Term Incentive Plan. As restrictions on resale end and so long as the registration statements are available for use, the market price of Class A Common Stock could decline if the holders of currently restricted shares sell them or are perceived by the market as intending to sell them.

The shares of Class A Common Stock registered for resale on this registration statement represent a majority of the shares Class A Common Stock that are or will be outstanding, and a significant number of those shares were purchased below the current trading price of our Class A Common Stock. Assuming all Class B Units of NuScale LLC are exchanged for shares of Class A Common Stock and assuming the removal of forfeiture restrictions applicable to 1,643,924 shares owned by the Spring Valley Founders, the approximate original sales price of the shares of Class A Common Stock registered for resale under this registration, and the approximate percentage of the total fully diluted shares of Class A Common Stock at June 9, 2022, assuming all outstanding options to purchase Class A Common Stock are exercised, would be: (a) 23,700,002 shares held by the PIPE Investors (approximately 10.1% of fully diluted shares), which were purchased at approximately $10.00 per share; (b) 5,514,933 shares held by the Spring Valley Founders (approximately 2.3% of fully diluted shares), which were purchased for $0.003 per share; and (c) 171,755,372 shares held by Legacy NuScale Equityholders (approximately 73.0% of fully diluted shares), which shares were originally purchased at various times since 2007 for ascribed prices per share ranging from approximately $0.00 (for certain incentive awards) to $7.76 per share, and which collectively have a weighted average ascribed purchase price of $4.74 per share. Even if our trading price is significantly below $10.00, the offering

TABLE OF CONTENTS

price for the units offered in our initial public offering, certain of the selling securityholders, including the Spring Valley Founders and the Legacy NuScale Equityholders (including Fluor), may still have an incentive to sell shares of our Class A Common Stock because they purchased the shares at prices lower than the Public Shareholders or the current trading price of our Class A Common Stock. For example, based on the closing price of our Class A Common Stock of $9.96 as of June 9, 2022, the Spring Valley Founders could experience a potential profit of up to approximately $9.96 per share, or $54.9 million in the aggregate. In addition, many of the Legacy NuScale Equityholders (including Fluor) have held equity securities in NuScale LLC for 10 years or more, and consequently may be more likely to sell some or all of their shares than would otherwise be the case.

NuScale Corp Warrants and Pre-Existing NuScale Options will become exercisable for Common Stock, which, if exercised, would increase the number of shares eligible for future resale in the public market and result in dilution to our stockholders.

Outstanding warrants to purchase an aggregate of 20,400,000 shares of Class A Common Stock will become exercisable June 1, 2022 in accordance with the terms of the warrant agreement governing those securities. The exercise price of these warrants will be $11.50 per share. In addition, outstanding options exercisable in exchange for an aggregate of 14,799,894 shares of Class A Common Stock are or will become exercisable in accordance with the terms of the NuScale LLC 2011 Equity Incentive Plan governing those securities. To the extent such warrants or options are exercised, additional shares of Class A Common Stock will be issued, which will result in dilution to the holders of Common Stock and increase the number of shares eligible for resale in the public market. Sales of substantial numbers of such shares in the public market or the fact that such warrants may be exercised could adversely affect the prevailing market prices of Class A Common Stock.

Investors’ ability to make transactions in NuScale Corp’s securities could be limited and if NuScale cannot maintain its listing on the NYSE, NuScale Corp may be subject to additional trading restrictions.

An active trading market for NuScale Corp’s securities may never develop or, if developed, it may not be sustained. In addition, NuScale Corp may be unable to maintain the listing of its securities on the NYSE in the future.

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” If NuScale Corp’s securities were not listed on the NYSE or another national securities exchange, such securities would not qualify as covered securities and we would be subject to regulation in each state in which we offer our securities because states are not preempted from regulating the sale of securities that are not covered securities.

You may not experience a rate of return on your investment in Class A Common Stock similar to the return experienced by existing stockholders, including those who hold shares that are registered for resale under this registration statement.

Our existing stockholders, including the selling securityholders, may experience a positive rate of return based on current trading prices of the Class A Common Stock. For example, based on the closing price of our Class A Common Stock of $9.96 as of June 9, 2022, the Spring Valley Founders could experience a potential profit of up to approximately $9.96 per share, or $54.9 million in the aggregate, and the Legacy NuScale Equityholders would realize a potential profit (on average) of approximately $5.22 per share, or $931.1 million in the aggregate. Similarly, if the Spring Valley Founders sold NuScale Corp Private Placements Warrants for $2.57 per warrant, the closing price of our warrants on June 9, 2022, the Spring Valley Founders would realize a potential profit of approximately $1.57 per warrant, or $14.0 million in the aggregate. Purchasers of Class A Common Stock or warrants in the offering made by this prospectus may not experience a similar rate of return, or any return, on their investment.

Reports published by analysts, including projections in those reports that differ from our actual results, could adversely affect the price and trading volume of our common stock.

Securities research analysts may establish and publish their own periodic projections for NuScale Corp. These projections may vary widely and may not accurately predict the results we actually achieve. Our share

TABLE OF CONTENTS

price may decline if our actual results do not match the projections of these securities research analysts. Similarly, if one or more of the analysts who write reports on us downgrades our stock or publishes inaccurate or unfavorable research about our business, our share price could decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, our share price or trading volume could decline. Moreover, if no analysts commence coverage of us, the market price and volume for our common shares could be adversely affected.

We are subject to changing law and regulations regarding regulatory matters, corporate governance and public disclosure that have increased and will continue to increase our costs and the risk of non-compliance.

We are subject to rules and regulations by various governing bodies, including the SEC, which are charged with the protection of investors and the oversight of companies whose securities are publicly traded, and to new and evolving regulatory measures under applicable law. Our efforts to comply with new and changing laws and regulations have resulted in, and likely will continue to result in, increased general and administrative expenses and a diversion of management time and attention.

Moreover, because these laws, regulations and standards are subject to varying interpretations, their application in practice may evolve over time as new guidance becomes available. This evolution may result in continuing uncertainty regarding compliance matters and additional costs necessitated by ongoing revisions to NuScale Corp’s disclosure and governance practices. If we fail to address and comply with these regulations and any subsequent changes, we may be subject to penalty and our business may be harmed.

We may be subject to securities litigation, which is expensive and could divert management attention.

The market price of our common stock may be volatile and, in the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert management’s attention from other business concerns, which could seriously harm our business.

DIVIDEND POLICY

We have no current plans to pay dividends on our Class A Common Stock. Our shares of Class B Common Stock represent solely the right to vote on matters submitted to the stockholders of NuScale Corp and have no rights to receive dividends or distributions or other economic rights. The declaration, amount, and payment of any future dividends on shares of Class A Common Stock is at the sole discretion of our Board, and we may reduce or discontinue entirely the payment of such dividends at any time. Our Board may take into account general and economic conditions, our financial condition and operating results, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax, and regulatory restrictions and implications on the payment of dividends by us to our stockholders or by our subsidiaries to us, and such other factors as our Board may deem relevant.

NuScale Corp is a holding company and has no material assets other than its ownership of NuScale LLC Class A Units. The A&R NuScale LLC Agreement provides that certain distributions to cover the taxes of the holders of NuScale LLC Class A Units and NuScale LLC Class B Units will be made based upon assumed tax rates and other assumptions provided in the A&R NuScale LLC Agreement. See “Certain Relationships and Related Person Transactions — A&R NuScale LLC Agreement.” NuScale Corp, as the manager of NuScale LLC, has broad discretion to make distributions out of NuScale LLC. If NuScale Corp declares any cash dividend, we expect that NuScale Corp, as manager of NuScale LLC, would cause NuScale LLC to make distributions to NuScale Corp in an amount sufficient to cover the cash dividends. If NuScale LLC makes distributions to NuScale Corp, the holders of NuScale LLC Class B Units will also be entitled to receive the respective equivalent pro rata distributions in accordance with the percentages of their respective NuScale LLC Class A Units and NuScale LLC Class B Units.

Cash received by NuScale LLC may, in certain periods, exceed its liabilities, including tax liabilities, and obligations to make payments under the Tax Receivable Agreement. NuScale Corp may use any such excess cash from time to time to pay dividends, which may include special dividends, on its Class A Common Stock, or to fund repurchases of its Class A Common Stock, or any combination of the foregoing. Our Board, in its sole discretion, will make any determination with respect to the use of any such excess cash.

We also expect, if necessary, to undertake ameliorative actions, which may include pro rata or non-pro rata reclassifications, combinations, subdivisions, or adjustments of outstanding NuScale LLC Class A Units and NuScale LLC Class B Units, or declare a stock dividend on our Class A Common Stock of an aggregate number of additional newly issued shares that corresponds to the number of additional NuScale LLC Class A Units and NuScale LLC Class B Units that NuScale Corp is acquiring, to maintain one-to-one parity between NuScale LLC Class A Units and NuScale LLC Class B Units and shares of Class A Common Stock and Class B Common Stock, respectively. See “Risk Factors — Risks Related to Our Organizational Structure — NuScale Corp’s sole material asset is its interest in NuScale LLC, and, accordingly, it will depend on distributions from NuScale LLC to pay its taxes and expenses, including payments under the Tax Receivable Agreement. NuScale LLC’s ability to make such distributions may be subject to various limitations and restrictions.”

Any financing arrangements that we enter into in the future may include restrictive covenants that limit our ability to pay dividends. In addition, NuScale LLC is generally prohibited under Oregon law from making a distribution to a member to the extent that, at the time of the distribution, after giving effect to the distribution, liabilities of NuScale LLC (with certain exceptions) exceed the fair value of its assets.

NuScale Corp has not paid any dividends to holders of its outstanding common stock since its formation on August 20, 2020. NuScale LLC has not paid dividends or made cash distributions to its equity holders since its formation on June 22, 2007.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

Introduction

The unaudited pro forma condensed combined balance sheet as of March 31, 2022 and the unaudited pro forma condensed combined statement of operations for the three months ended March 31, 2022 and the year ended December 31, 2021 present the historical financial statements of Spring Valley and NuScale LLC, adjusted to reflect the Transactions. The unaudited condensed combined pro forma balance sheet as of March 31, 2022 gives pro forma effect to the Transactions and related transactions as if they had occurred on March 31, 2022. The unaudited pro forma condensed combined statements of operations data for the three months ended March 31, 2022 and the year ended December 31, 2021 gives pro forma effect to the Transactions and related transactions as if they had been consummated on January 1, 2021. The unaudited pro forma condensed combined financial information has been prepared in accordance with Regulation S-X, as amended.

The Transactions include:

•

the merger of Merger Sub, a wholly owned subsidiary of Spring Valley, with and into NuScale LLC, with NuScale LLC surviving the merger as a subsidiary of Spring Valley;

•

the reverse recapitalization between Spring Valley and NuScale LLC;

•

the conversion of the aggregate principal balance of Fluor Convertible Notes into NuScale LLC Units, (which will then be converted into and exchanged for NuScale LLC Class B Units and Class B Common Stock); and

•

the issuance and sale of 23,700,002 shares of Class A common stock for a purchase price of approximately $10.00 per share and an aggregate purchase price of $235,000,000 in the PIPE Investment pursuant to the Subscription Agreements;

The unaudited pro forma condensed combined financial information has been developed from and should be read in conjunction with:

•

the notes accompanying the unaudited pro forma condensed combined financial statements;

•

the historical audited financial statements of Spring Valley included elsewhere in this prospectus;

•

the historical audited financial statements of NuScale LLC set forth in this prospectus;

•

the discussion of the financial condition and results of operations of Spring Valley and NuScale LLC set forth in this prospectus; and

•

other information contained in this prospectus.

Upon the Closing, Legacy NuScale Equityholders held securities exchangeable for an aggregate of 178,396,711 shares of Class A Common Stock (or, upon the election of NuScale Corp, cash in an amount equal to the net proceeds raised by selling such Class A Common Stock in a contemporaneous underwritten offering). In addition, NuScale Corp assumed all outstanding NuScale Options and the holders of those NuScale Options will be entitled to receive up to 14,799,894 shares of Class A Common Stock upon exercise. The assumed NuScale Options are subject to vesting conditions. The Transactions were accomplished through an “UP-C” structure and the type and mix of consideration received by the Legacy NuScale Equityholders reflect the implementation of such structure.

Pursuant to the Tax Receivable Agreement, NuScale Corp will be required to pay 85% of the net cash tax savings from certain tax benefits, if any, that it realizes (or in certain cases is deemed to realize) as a result of any increases in tax basis and other tax benefits resulting from any exchange by the TRA Holders of NuScale LLC Class B Units for shares of Class A Common Stock or, upon the election of NuScale Corp, cash in an amount equal to the net proceeds raised by selling such Class A Common Stock in a contemporaneous underwritten offering, in the future. Any such payments to TRA Holders will reduce the cash provided by the tax savings generated from future exchanges that would otherwise have been available to NuScale Corp for other uses, including reinvestment or dividends to Class A stockholders. Cash tax savings from the remaining 15% of the tax benefits will be retained by NuScale Corp. NuScale Corp’s

TABLE OF CONTENTS

obligations under the Tax Receivable Agreement accelerate upon a change in control and certain other termination events, as defined therein.

NuScale Corp expects to benefit from the remaining 15% of cash savings. Due to the uncertainty of the amount and timing of future exchanges of NuScale LLC Class B Units, the unaudited pro forma condensed combined financial information assumes that no exchanges of NuScale LLC Class B Units have occurred and therefore, no increases in tax basis have been realized. Additionally, NuScale Corp would recognize a full valuation allowance for any deferred tax asset realized based on NuScale LLC’s current assessment of the future realizability.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

1. Basis of Presentation

The unaudited pro forma condensed combined financial information has been prepared to illustrate the estimated effect of the Transactions.

The Transactions are shown as a reverse recapitalization as provided under U.S. GAAP. Spring Valley is the acquired company, with NuScale LLC treated as the acquirer. This determination reflects Legacy NuScale Equityholders holding a majority of the voting power of NuScale Corp, NuScale LLC’s pre-merger operations being the majority post-merger operations of NuScale Corp, and NuScale LLC’s management team retaining similar roles at NuScale Corp. Accordingly, although Spring Valley is the legal parent company, GAAP dictates that the financial statements of NuScale Corp will represent a continuation of NuScale LLC’s operations, with the Transactions being treated as though NuScale LLC issued ownership interests for Spring Valley, accompanied by a recapitalization. The net assets of NuScale LLC are stated at historical cost, with no incremental goodwill or other intangible assets recorded for the effects of the Merger with Spring Valley.

2. Reclassifications

Certain reclassification adjustments have been made to conform Spring Valley’s historical financial statement presentation to that of NuScale LLC’s as follows:

	Balance Sheet as of March 31, 2022
	Spring Valley Before Reclassifications			Reclassification Adjustments			Spring Valley After Reclassifications
Accounts payable and accrued expenses		$	—		$	5,056		$	5,056
Accounts payable			110			(110)			—
Accrued expenses			4,946			(4,946)			—

3. Transaction Accounting Adjustments

The unaudited pro forma condensed combined financial information reflects:

(A)

The reclassification of investments held in the Trust Account that becomes available at the Closing. Accordingly, cash and cash equivalents increased $232.3 million with elimination of investments held in the Trust Account.

(B)

The gross proceeds of $235,000,000 from the PIPE Investment, in which 23,700,002 shares of Class A Common Stock were issued pursuant to the Subscription Agreements. Accordingly, cash and cash equivalents increased by $235,000,000, with a corresponding increase in equity.

(C)

Estimated transaction costs in connection with the Transactions of $42.7 million, of which $0.7 million was previously paid and recorded to accumulated deficit, $0.4 million was previously recorded to other assets and accounts payable and accrued expenses, and $1.9 million was previously paid and recorded to other assets. Of the total, $29.7 million relates to advisory, legal, and other fees to be incurred, $4.9 million relates to estimated PIPE Investment fees and $8.1 million relates to deferred underwriting fees. Of these expenses, $32.1 million are expected to be recorded in additional paid-in capital and $2.5 million is expected to be recorded to accumulated deficit, while the remaining $8.1 million is related to settlement of deferred underwriting fees payable.

(D)

The reclassification of Spring Valley Class A ordinary shares subject to possible redemption to Class A Common Stock.

(E)

The recapitalization of NuScale LLC’s equity and issuance of 178,396,711 shares of Class B Common Stock as consideration for the reverse recapitalization. Existing NuScale LLC common and preferred units have been reclassified to common stock and additional paid-in capital at carrying value, including NuScale LLC common units previously presented as mezzanine equity.

TABLE OF CONTENTS

(F)

The reclassification of the Spring Valley Founder Shares from Spring Valley Class B ordinary shares to Spring Valley Class A ordinary shares at the Closing.

(G)

The reclassification of Spring Valley’s historical accumulated deficit to additional paid-in capital as part of the reverse recapitalization.

(H)

The conversion of a note payable from NuScale LLC to Fluor into NuScale LLC Common Units, which are subsequently re-classified in the Merger as 8,257,560 NuScale LLC Class B Units, and the related issuance in the Transactions of an equal number of shares of Class B Common Stock (see (J) for subsequent adjustments to reflect Legacy NuScale Equityholders’ economic interest in NuScale LLC). Accordingly, additional paid-in capital increases by $14.0 million with an equal decrease to convertible notes payable.

(I)

Amounts paid to the Public Shareholders who exercised their redemption rights. 8,599,631 Spring Valley Class A ordinary shares were redeemed for aggregate redemption payments of $86.9 million. The redemptions at a redemption price of $10.10 per share results in a reduction to equity with a corresponding decrease in investments held in the Trust Account.

(J)

An adjustment to reflect noncontrolling interest holders’ economic share of combined equity, pursuant to the post-combination structure of the combined companies. Following the Closing, holders of Class A Common Stock own direct controlling interests in the results of the combined entity, while the Legacy NuScale Equityholders own an economic interest in NuScale LLC shown as noncontrolling interest in equity in the financial statements of NuScale Corp. The indirect economic interests are held by the Legacy NuScale Equityholders in the form of NuScale LLC Class B Units that, together with the cancellation for no consideration of Class B Common Stock, can be exchanged, at the election of the holder of NuScale LLC Class B Units and Class B Common Stock, for Class A Common Stock or, in certain circumstances including at the election of NuScale Corp, cash in an amount equal to the fair value of Class A Common Stock. If NuScale Corp elects that the exchanged NuScale LLC Class B Units, together with cancellation for no consideration of Class B Common Stock, will be settled in cash, the cash used to settle the exchange must be funded through an underwritten offering of Class A Common Stock.

The following table summarizes the economic interests of NuScale Corp between the holders of Class A Common Stock and indirect economic interests held by NuScale LLC Class B Unitholders (assuming all NuScale LLC Class B Units are exchanged for Class A Common Stock):

	Economic Interests		% of Economic Interests
NuScale Corp Class A Common Stock		41,971,380		19.0%
NuScale Class B Units (Noncontrolling interest)		178,396,711		81.0%
		220,368,091		100.0%

The noncontrolling interest may decrease according to the number of shares of Class B Common Stock and NuScale LLC Class B Units that are exchanged for shares of Class A Common Stock or, in certain circumstances including at the election of NuScale Corp, cash in an amount equal to the fair value of Class A Common Stock. The calculation of noncontrolling interest is based on the net assets of NuScale Corp following the completion of the Transactions. Accordingly, noncontrolling interest increased to $285.4 million with a corresponding decrease in additional paid-in capital and accumulated deficit.

(K)

Adjustments for deferred taxes, which arise from differences between the financial statement and tax basis in the NuScale LLC interests, including legacy step-up basis adjustments, and net operating losses recorded at NuScale Corp. The adjustments for deferred taxes assume:

the GAAP balance sheet as of March 31, 2022 is adjusted for the pro forma entries described herein,

TABLE OF CONTENTS

II.

the estimated tax basis as of March 31, 2022 is adjusted for the pro forma entries described herein,

III.

a full valuation allowance is established to offset the net deferred tax assets based upon the assessment of realizability, and

IV.

no material changes in tax law.

NuScale Corp accrues liabilities or adjusts deferred taxes for unrecognized tax benefits. NuScale Corp has not recorded any unrecognized tax benefits as of March 31, 2022, that, if recognized, would affect its annual effective tax rate. However, as NuScale Corp continues to evaluate various accounting considerations, it may record uncertain tax positions under GAAP.

(L)

No adjustments are reflected for the effects of the Tax Receivable Agreement, more fully described elsewhere in this prospectus. As part the Closing, NuScale Corp is a party to a Tax Receivable Agreement under which NuScale Corp will make payments to the TRA Holders in respect of 85% of the net tax benefit to NuScale Corp of certain tax attributes. NuScale Corp anticipates that it will account for the income tax effects resulting from future taxable exercises of the exchange rights set forth in the A&R NuScale LLC Agreement by recognizing an increase in deferred tax assets, based on enacted tax rates at the date of each exchange. If there were an exchange of all the outstanding NuScale LLC Class B Units immediately after the Transaction, the estimated tax benefits to NuScale Corp, subject to the Tax Receivable Agreement, would be approximately $604.8 million offset by related undiscounted payment to the TRA Holders equal to 85% of the benefit received of $514.1 million based on certain assumptions, including that NuScale Corp has sufficient taxable income to realize the tax benefit; there are no material tax law changes; and the fair market value of the exchanged shares is equal to $10 per share. At this time, a full valuation allowance would be established on any deferred tax asset created based on NuScale LLC’s current assessment of the future realizability. Therefore, no liability related to future TRA payments has been reflected.

(M)

The estimated change in interest expense for the assumed conversion of the Fluor Convertible Note (refer to adjustment (H) for details). Accordingly, interest expense decreased by $0.1 million for the three months ended March 31, 2022, and $0.4 million for the year ended December 31, 2021.

(N)

The net loss of NuScale Corp being reduced as summarized below.

(amounts in thousands)	Three months ended March 31, 2022		Year ended December 31, 2021
Pro forma net loss		(39,249)		(102,120)
Noncontrolling interest percentage		81.0%		81.0%
Noncontrolling interest pro forma adjustment		(31,792)		(82,717)
Net loss attributable to NuScale Corp		(7,457)		(19,403)

(O)

The elimination of income earned on the Trust Account.

(P)

The net loss per share calculated using the weighted average shares outstanding and the issuance of additional shares of Class A Common Stock in connection with the Transactions, assuming that the shares were outstanding since January 1, 2021. The calculation of weighted average shares outstanding for net loss per share assumes that the shares issued related to the Transactions have been outstanding for the entire period presented.

The unaudited pro forma condensed combined financial information reflects a net loss for NuScale Corp and therefore all potentially dilutive securities are anti-dilutive.

In addition, each NuScale LLC Class B Unit may be exchanged, together with the cancelation for no consideration of an equal number of shares of Class B Common Stock for no consideration, for (i) one share of Class A Common Stock, subject to conversion rate adjustments for stock splits, stock dividends and reclassification, or (ii) an equivalent amount of cash, subject to certain

TABLE OF CONTENTS

restrictions. If all NuScale LLC Class B Units and Class B Common Stock were exchanged immediately following the Transactions, Class A Common Stock outstanding would increase by 178,396,711 shares. In computing the dilutive effect, if any, the net income available to holders of Class A Common Stock would increase due to elimination of the noncontrolling interest associated with the NuScale LLC Class B Units (including any tax impact). For the periods presented, such exchange is not reflected in the earnings per share calculation as the assumed exchange would be anti-dilutive.

(amounts in thousands, except share and per share amounts)	Three months ended March 31, 2022		Year ended December 31, 2021
Pro forma net loss attributable to NuScale Corp		(7,457)		(19,403)
Weighted average NuScale Corp Class A Common Stock outstanding, basic and diluted		41,971,380		41,971,380
Net loss per share of NuScale Corp Class A Common Stock, basic and diluted		(0.18)		(0.46)
Spring Valley Class A Shareholders		14,400,369		14,400,369
Spring Valley Founders		3,871,009		3,871,009
PIPE Investors		23,700,002		23,700,002
Pro forma shares outstanding, basic and diluted		41,971,380		41,971,380

(Q)

An adjustment for $1.8 million of estimated transaction costs in connection with the Transactions expected to be incurred during the first annual period post-close, excluding $0.7 million already incurred during the year ended December 31, 2021. Such costs are non-recurring and were reflected as if incurred on January 1, 2021, the date the Transactions occurred for the purposes of the unaudited pro forma condensed combined statements of operations.

(R)

An adjustment to reflect the cash settlement of Unit Appreciation Rights awarded to John L. Hopkins, which were exercised and cash settled for $1.5 million prior to the Closing. Incremental compensation expense is equal to the excess of the fair value at the time of cash settlement over the grant date fair value. No Class A Common Stock was issued to Mr. Hopkins in settlement of the Unit Appreciation Rights.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of the financial condition and results of operations of NuScale Power, LLC (“NuScale LLC”) should be read together with our financial statements as of and for the years ended December 31, 2021 and 2020 and unaudited interim condensed financial statements as of and for the three months ended March 31, 2022 and 2021, together with related notes thereto. The discussion and analysis should also be read together with the section entitled “Historical Business of NuScale LLC” and our pro forma financial information as of and for the year ended December 31, 2021. See “Unaudited Pro Forma Condensed Combined Financial Information.” This discussion may contain forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those projected in these forward-looking statements as a result of various factors, including those set forth under “Risk Factors” or in other parts of this prospectus. Unless the context otherwise requires, references in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations of NuScale LLC” section to “NuScale LLC,” “us,” “our” or “we” refer to NuScale LLC prior to the Merger, and to NuScale Power, Corporation (“NuScale Corp”) following the consummation of the Transactions.

Overview

Our mission is to provide scalable advanced nuclear technology for the production of electricity, heat, and clean water to improve the quality of life for people around the world. We are changing the power that changes the world by creating an energy source that is smarter, cleaner, safer and cost competitive.

Our SMR, known as NPM, provides a scalable power plant solution incorporating enhanced safety, improved affordability and extended flexibility for diverse electrical and process heat applications. Our scalable design provides carbon-free energy and at a reduced cost when compared with gigawatt-sized nuclear facilities.

Since our founding in 2007, we have made significant progress towards commercializing the first SMR in the United States. In 2017, we submitted our Design Certification Application (“DCA”) to the NRC. On August 28, 2020, the NRC issued its Final Safety Evaluation Report, representing the NRC’s completion of its technical review. On September 11, 2020 the NRC issued its SDA of our NPM and scalable plant design. With this phase of NuScale LLC’s DCA now complete, customers may proceed with plans to develop NuScale power plants with the understanding that the NRC has approved the safety aspects of the NPM and plant design. We expect our operating losses and negative operating cash flows to grow until the commercialization of the NPM.

The Transactions

We entered into the Merger Agreement with Spring Valley and Merger Sub on December 13, 2021. Pursuant to the Merger Agreement, on May 2, 2022, Merger Sub merged with and into NuScale LLC with NuScale LLC surviving the Merger as a wholly owned subsidiary of Spring Valley. Spring Valley was then renamed NuScale Power Corp.

The Merger was accounted for as a reverse recapitalization as provided under U.S. GAAP. NuScale LLC was deemed the predecessor and NuScale Corp is the successor SEC registrant, meaning that NuScale LLC’s financial statements for previous periods will be disclosed in NuScale Corp’s future periodic reports filed with the SEC. Spring Valley was treated as the acquired company for financial statement reporting purposes. The most significant change in NuScale Corp’s future reported financial position and results is a net increase in cash (as compared to NuScale LLC’s financial position as of March 31, 2022) of $341.0 million.

TABLE OF CONTENTS

Immediately after giving effect to the Transactions and PIPE Investment NuScale Corp’s common stock consisted of the following:

	Ownership %
Spring Valley’s public shareholders		6.5%
Legacy NuScale Equityholders (excluding public shares held prior to the Merger)		80.4%
Spring Valley Acquisition Sponsor, LLC and related parties		2.4%
PIPE Investors		10.7%
Total NuScale Corp common stock		100.0%

Key Factors Affecting Our Prospects and Future Results

We believe that our performance and future success depend on a number of factors that present significant opportunities for us but also pose risks and challenges, including competition from carbon-based and other non-carbon-based energy generators, the risk of perceived safety issues and their consequences for our reputation and the other factors discussed under the section titled “Risk Factors.” We believe the factors described below are key to our success.

Commencing and Expanding Commercial Launch Operations

In September 2020, we became the first and only company to receive NRC SDA for an SMR. We believe our commercialization activities are being completed at a pace that can support delivery of modules to a client site as early as 2027. We have an agreement in place with UAMPS to deploy a NuScale 6-module power plant at the DOE’s Idaho National Laboratory as part of UAMPS’ CFPP. Commercial operation of that power plant is slated for 2029. In November 2021, we signed a teaming agreement with S.N. Nuclearelectrica S.A., an entity that operates under the authority of the Romanian Ministry of Energy, to advance the deployment of our NPMs to Romania. Under the teaming agreement, we will evaluate activities associated with the planning, siting and licensing of our NuScale power plant technology at a site that is the location of an existing coal-fueled electricity plant. We expect the site in Romania to use six modules and to be commercially operable by 2028.

We have over 100 potential target customers, including, in addition to UAMPS, ten customers across seven countries that we consider highly interested customers who are considering an NPM power plant deployment in the late 2020s or early 2030s. We believe the long lead-time involved with siting an SMR, the number of customers in our pipeline and the work being performed by these potential customers involving a NuScale deployment project bode well for our potential future success.

Regulatory Approvals

We expect to submit an application to the NRC for our latest power enhanced design. If approved, the licensed output of our NPM will be raised from 50 MWe to 77 MWe. Approval of the design, which could come in 2024, would increase the cost-competitiveness of our NPM, and we consider obtaining such approval a critical milestone.

Other factors that we believe are critical to our future success are country-level approvals of our NPM design. We also believe site-approvals by our customers to be key to facilitating broader adoption of our products and services. Obtaining these approvals before others is critical in maintaining our competitive advantage.

Successful Implementation of the First NPM Power Plant

A critical step in our success will be the successful construction and operation of the first power plant using our NPM. We expect that the first NPM for the UAMPS facility could be operational as early as 2029 with the remaining five modules achieving commercial operation in 2030.

Key Components of Results of Operations

We are an early-stage company and our historical results may not be indicative of our future results. Accordingly, the drivers of our future financial results, as well as the components of such results, may not be comparable to our historical or future results of operations.

TABLE OF CONTENTS

Revenue

We have not generated any material revenue to date. All revenue that we have generated to date arises from engineering and licensing services provided to potential customers. As a result of those front end engineering and development services, we expect to generate a significant portion of our revenue from the sale of NPMs. We also expect to generate revenue by providing critical services, such as start-up and testing and nuclear fuel and refueling services, over the life cycle of each power plant.

Expenses

Research and Development Expense

Our R&D expenses consist primarily of internal and external expenses incurred in connection with our R&D activities. These expenses include labor directly performed on our projects and fees paid to third parties working on and testing specific aspects of our NPM design. R&D costs have been expensed as incurred. We expect R&D expenses to grow as we continue to develop the SMR technology and develop market and strategic relationships with other businesses.

General and Administrative Expense

G&A expenses consist of compensation costs for personnel in executive, finance, accounting, human resources and other administrative functions. G&A expenses also include legal fees, professional fees paid for accounting, auditing, and consulting services, insurance costs and facility costs. Following the Transactions, we expect we will incur higher G&A expenses for public company costs such as compliance with the regulations of the SEC and the NYSE.

Other Operating Expense

Other operating expenses consist primarily of compensation costs (including indirect benefits and stock-based compensation expense) for operating personnel that cannot be directly attributed to a project.

Department of Energy Cost Share

The DOE cost share amounts reflect our cost-sharing arrangement with the DOE. Generally, as our qualifying operating costs change, there is a corresponding change in the reimbursable amounts. The amount of any reimbursement is recognized in the period that we recognize the qualifying expenses.

Income Tax Effects

We are a limited liability company that is treated as a partnership for tax purposes, with each of our members accounting for its share of tax attributes and liabilities. Accordingly, there are no current or deferred income tax amounts recorded in our financial statements.

TABLE OF CONTENTS

Research and Development

A breakdown of R&D costs by nature for the years ended December 31, 2021 and 2020 is presented below:

	Year Ended December 31,
(in thousands)	2021			2020
Research and development expenses:
Professional fees		$	64,815		$	63,856
Personnel costs			28,086			31,264
Other			235			165
Total		$	93,136		$	95,267

The decrease in personnel costs was driven by the fact that the NRC’s review of the NPM design application concluded in late 2020.

General and Administrative

The increase in 2021 G&A expenses was primarily due to an increase in compensation and benefits of $4.5 million, a contract settlement fee with a former advisor of $3.3 million and $2.2 million related to higher advertising costs, partially offset by lower equity-based compensation of $0.5 million.

Other Operating Expense

Other operating expenses increased year over year as a result of higher compensation costs of $6.2 million, equity-based compensation of $3.2 million and $0.5 million in various other expenses, partially offset by lower professional fees of $1.0 million.

Liquidity and Capital Resources

Liquidity

We measure liquidity in terms of our ability to fund the cash requirements of our R&D activities and our near term business operations, including our contractual obligations and other commitments. Our current liquidity needs primarily involve R&D activities for the ongoing development of the NPM and associated plant design.

We had $42.7 million in cash and cash equivalents as of March 31, 2022 (compared to $77.1 million as of December 31, 2021). We also had total debt of $14.1 million as of March 31, 2022 (compared to $14.0 million as of December 31, 2021), representing outstanding principal and accrued interest on the Fluor Convertible Note.

Since inception, we have incurred significant operating losses, have an accumulated deficit of $805.0 million and negative operating cash flow during the three months ended March 31, 2022 and 2021. Management expects that operating losses and negative cash flows may increase because of additional costs and expenses related to the development of technology and the development of market and strategic relationships with other companies.

To date, we have not generated any material revenue. We do not expect to generate any meaningful revenue unless and until we are able to commercialize our NPM and related services. We expect our costs to increase in connection with advancement of our products and services toward commercialization. In addition, we expect to incur additional costs associated with operating as a public company. While we believe that the proceeds of the Transactions will be sufficient to reach commercialization of our NPM, certain costs are not reasonably estimable at this time and we may require additional funding and our projections anticipate certain customer-sourced income that is not assured.

As noted above, following the Merger and the closing to the PIPE Investment, we received approximately $341 million in cash, net of transaction expenses, to fund our operations and R&D activities. The gross

TABLE OF CONTENTS

amount, before expenses, was composed of approximately $145.5 million released from the Trust Account, after payment of approximately $86.9 million to Public Shareholders who exercised redemption rights (representing a redemption rate of approximately 37.5%), and approximately $235 million in proceeds from the PIPE Investment. We believe that based on our current level of operating expenses and currently available cash resources, we will have sufficient funds available to cover R&D activities and operating cash needs for several years. However, considering that we have not yet developed a commercial product and have no meaningful revenue to date, we may require additional funds in future years. Our ability to raise funds through equity offerings may be limited by the significant number of shares that may be publicly sold, including the shares registered for resale under this registration statement. Such sales may negatively affect the market price of our Class A Common Stock. In particular, a large sale by Fluor, our majority shareholder, could significantly affect our stock price. See “Risk Factors — Commercialization Risk Factors — We May Require Additional Funding.” 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. See “Description of Capital Stock — Warrants.” Our ability to fund R&D activities and our operating cash needs for several years does not depend on the proceeds we may receive as the result of exercises of warrants.

Summary Statement of Cash Flows for the Three Months Ended March 31, 2022 and 2021

The following table sets forth the primary sources and uses of cash and cash equivalents for the periods presented below:

	Three Months Ended March 31,
(in thousands)	2022			2021
Net cash used in operating activities		$	(33,151)			(29,787)
Net cash used in investing activities			(1,187)			(111)
Net cash (used in) provided by financing activities			(73)			63,211
Net (decrease) increase in cash and cash equivalents		$	(34,411)		$	33,313

Cash Flows used in Operating Activities

Our operating cash flow decreased during the three months ended March 31, 2022 as a result of higher cash payments for compensation costs, partially offset by a significant increase in accounts receivable during the three months ended March 31, 2021.

Cash Flows from Financing Activities

During the three months ended March 31, 2021, net cash provided by financing activities consisted of proceeds from the incurrence of debt of $22.7 million in the form of a line of credit promissory note with Fluor, and $40.5 million from the sale of convertible preferred units. We had no such activity for the three months ended March 31, 2022.
