Cautionary Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act that are not historical facts and involve risks and uncertainties that could cause actual results to differ materially from those expected and projected. All statements, other than statements of historical fact included in this Form 10-Q, including, without limitation, statements regarding our financial position and business strategy and the expectations, beliefs, intentions, plans and objectives of management for future operations, are forward-looking statements. Words such as “expect,” “believe,” “anticipate,” “intend,” “continue,” “could,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “will,” “would,” “estimate,” “seek” and variations and similar words and expressions are intended to identify such forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements in this Quarterly Report may include, for example, statements about:

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

•the ability to obtain regulatory approvals to deploy our SMRs in the United States and abroad;

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

•macroeconomic conditions;

•developments and projections relating to our competitors and industry;

•our anticipated growth rates and market opportunities;

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

•litigation contingencies;

•financial arrangements with CFPP LLC;

•the estimated amounts to be reimbursed to CFPP LLC and costs related to termination of the DCRA and LLM Agreement;

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

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

Such forward-looking statements relate to future events or future performance, but reflect management’s current beliefs, based on information currently available. Many factors could cause actual events, performance or results to differ materially from the events, performance and results discussed in the forward-looking statements, and there can be no assurance that future developments affecting us will be those we have anticipated.

Important factors that could cause actual results to differ materially from those anticipated in the forward-looking statements, are described in the section titled “Risk Factors” included in our 2022 Annual Report on Form 10-K. If one or more of those risks or uncertainties materialize, or if any of our assumptions prove incorrect, actual results may vary in material respects from those projected in those forward-looking statements. There may be additional risks that we currently consider immaterial, or which are unknown. It is not possible to predict or identify all such risks. Except as expressly required by applicable securities law, we disclaim any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise. No person should take any statement regarding past trends or activities as a representation that the trends or activities will continue in the future.

Notes to the Unaudited Condensed Consolidated Financial Statements

(in thousands, except shares and per share amounts)

1.Nature of Business

Organization and Operations

NuScale Power Corporation (“NuScale Corp”, the “Company”, “us”, “we” or “our”) is commercializing a modular, scalable 77 MWe (gross) light water reactor nuclear power plant using exclusive rights to a nuclear power plant design obtained from Oregon State University. The Company is majority owned by Fluor.

Merger with Spring Valley

In December 2021, NuScale LLC entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Spring Valley Acquisition Corp. (“Spring Valley”) and Spring Valley Merger Sub, LLC (“Merger Sub”), a wholly owned subsidiary of Spring Valley. Pursuant to the Merger Agreement, Merger Sub merged with and into NuScale LLC (the “Merger”), with NuScale LLC surviving the Merger (the “Surviving Company”), Spring Valley being renamed NuScale Corp, and NuScale LLC continuing to be held as a wholly controlled subsidiary of NuScale Power Corporation in an “Up-C” structure. On May 2, 2022, the Merger Agreement and Merger (collectively the “Transaction”) was completed.

The Transaction is shown as a reverse recapitalization under United States Generally Accepted Accounting Principles (“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 NuScale Corp (f/k/a Spring Valley) is the parent company, GAAP dictates that the financial statements of NuScale Corp represent a continuation of NuScale LLC’s operations, with the Transaction 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 Transaction. The consummation of the Transaction resulted in NuScale LLC receiving cash equal to $341.5 million and assuming Warrant liabilities valued at $47.5 million.

2.Summary of Significant Accounting Policies

Basis of Presentation

The Company’s unaudited condensed consolidated financial statements and related notes do not include notes and certain financial information normally presented annually under GAAP, and therefore should be read in conjunction with our 2022 Annual Report on Form 10-K. Accounting measures at interim dates inherently involve greater reliance on estimates than at year-end. Although such estimates are based on management’s most recent assessment of the underlying facts and circumstances utilizing the most current information available, our reported results of operations may not necessarily be indicative of results that we expect for the full year.

These financial statements are unaudited. In management’s opinion, they contain all adjustments of a normal recurring nature which are necessary to present fairly our financial position and our operating results as of and for the interim periods presented.

Principles of Consolidation

As part of the Transaction, NuScale Corp has been determined to be the primary beneficiary of NuScale LLC, a variable interest entity (“VIE”). As the sole managing member of NuScale LLC, NuScale Corp has both the power to direct the activities, and direct ownership to share in the revenues and expenses of NuScale LLC. As such, all the activity of NuScale LLC has been consolidated in the accompanying condensed consolidated financial statements. All assets and liabilities included in the balance sheet are that of NuScale LLC, other than the NuScale Corp Warrants and certain prepaid insurance. All significant intercompany transactions have been eliminated upon consolidation.

Changes in Presentation

For the three and nine months ended September 30, 2022, amounts totaling $39 and $154, respectively, were previously included in Interest income (expense) and have been reclassified to Sponsored cost share to conform to the current year presentation on the accompanying condensed consolidated statements of operations. No such reclassifications were required for the 2023 fiscal year.

For the three months ended September 30, 2022, amounts totaling $987 and $1,001 were reclassified out of G&A expenses and into R&D expenses and Other expenses, respectively, to conform to the current year presentation. During the nine months ended September 30, 2023, R&D expenses totaling $1,855 were reclassified to Other expenses to conform to the current year presentation, while for the nine months ended September 30, 2022, $2,348 and $3,115 have been reclassified out of G&A expenses and into R&D expenses and Other expenses, respectively, to conform to the current year presentation.

Cash, Cash Equivalents and Restricted Cash

Cash equivalents represent short-term, highly liquid investments, which are readily convertible to cash and have maturities of three months or less at time of purchase. Cash equivalents with an initial maturity of between three and twelve months at time of purchase are presented as short-term investments on the accompanying condensed consolidated balance sheet. Cash equivalents and Short-term investments consist of certificates of deposit. These certificates of deposit are classified as held-to-maturity, and the estimated fair value of the investment approximates its amortized cost.

Cash in the amount of $79,164 was restricted as collateral for the letter of credit associated with the Development Cost Reimbursement Agreement (“DCRA”) at September 30, 2023 (See Note 13). The DCRA spans multiple years requiring the amount to be classified as a noncurrent asset, included in Restricted cash in the accompanying condensed consolidated balance sheet. The restricted cash balance plus Cash and cash equivalents on the accompanying condensed consolidated balance sheet equals cash, cash equivalents and restricted cash, as reflected in the accompanying condensed consolidated statements of cash flows.

Sales and Marketing Agreements

The Company has entered into sales and marketing agreements pursuant to which it prepaid certain expenses to the counterparty. As of September 30, 2023, the current portion of $16,200 and noncurrent portion of $3,750, are included in Prepaid expenses and Other assets, respectively, on the accompanying condensed consolidated balance sheet and will be amortized monthly on a straight line basis through the period ended December 31, 2024.

Warrant Liability

The Company accounts for the Warrants in accordance with the guidance contained in Accounting Standards Codification (“ASC”) 815, “Derivatives and Hedging”, under which the Warrants do not meet the criteria for equity treatment and must be recorded as liabilities. Accordingly, the Company classifies the Warrants as liabilities at their fair value and adjusts the Warrants to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s condensed consolidated statements of operations. The fair value of the Public and Private Placement Warrants has been estimated using the Public Warrants’ quoted market price. See note 4 for further discussion of the terms of the Warrants and note 5 for further discussion of the methodology used to determine the value of the Warrants.

Sponsored Cost Share

As our commercialization activities advance, we have continued to enter into cost share agreements with various entities, including both governmental and private, under which the Company is reimbursed for specific R&D activities.

NuScale Power Corporation

Notes to the Unaudited Condensed Consolidated Financial Statements

(in thousands, except shares and per share amounts)

As of September 30, 2023, these entities include the DOE, United States Department of State and United States Trade and Development Agency (combined as “USG”), CFPP LLC and RoPower Nuclear S.A.

Since 2014, the DOE has provided critical funding to the Company through a series of cooperative agreements that support ongoing commercialization activities. During the three months ended September 30, 2023 and 2022, DOE cost share totaled $9,171 and $18,382, respectively, while for the nine months ended September 30, 2023 and 2022, DOE cost share totaled $28,718 and $64,016, respectively.

Beginning in 2021, the Company partnered with USG to develop SMRs in foreign markets. Under USG’s technical assistance grant programs, we receive cost share commitments to support licensing work in these foreign markets, one of which is additionally supported by RoPower Nuclear S.A. During the three months ended September 30, 2023 and 2022, USG cost share totaled $10,521 and $39, respectively, while during the nine months ended September 30, 2023 and 2022, USG cost share totaled $20,080 and $154, respectively.

Finally, we received subrecipient cost share from CFPP LLC under a contract between the DOE and UAMPS for R&D performed with the goal of developing our first SMR. Under this agreement we received cost share of $1,082 and $6,186 during the three and nine months ended September 30, 2023, with no cost share during the same periods in the prior year. We have agreed to terminate our agreements with CFPP LLC (see Note 8).

3. Noncontrolling Interests and Loss Per Share

Noncontrolling Interests

Following the Transaction, 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 interests (“NCI”) in equity in NuScale Corp’s condensed consolidated financial statements. The indirect economic interests are held by Legacy NuScale Equityholders in the form of NuScale LLC Class B Units. 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 as of and for the three and nine months ended September 30, 2023 and 2022:

Loss Per Share

Prior to the Transaction, the membership structure of NuScale LLC included units that had profit interests. The Company analyzed the calculation of net loss per unit for periods prior to the Transaction and determined that it resulted in values that would not be meaningful to the readers of these financial statements. Therefore, net loss per unit information has not been presented for periods prior to May 2, 2022.

Basic loss per share is based on the average number of shares of Class A common stock outstanding during the period. Diluted loss per share is based on the average number of shares of Class A common stock used for the basic earnings per share calculation, adjusted for the dilutive effect of RSUs, Stock Options and Warrants using the “treasury stock” method and for all other interests that convert into potential shares of Class A common stock, if any, using the “if converted” method. Net loss attributable to Class A common stockholders for diluted loss per share is adjusted for the Company’s share of NuScale LLC’s net loss, net of NuScale Corp taxes, after giving effect to all other interests that convert into potential shares of Class A common stock, to the extent it is dilutive. In addition, net loss attributable to Class A common stockholders for diluted loss per share is adjusted for the after-tax impact of changes to the fair value of derivative liabilities, to the extent the Company’s Warrants are dilutive.

The following table sets forth the computation of basic and diluted net loss per share of Class A common stock and represents the three and nine months ended September 30, 2023, the period where the Company had Class A and Class B common stock outstanding. Class B common stock represents a right to cast one vote per share at the NuScale Corp level, and carry no economic rights, including rights to dividends or distributions upon liquidation, and as a result, is not considered a participating security for basic and diluted loss per share. As such, basic and diluted loss per share of Class B common stock has not been presented.


	As of and for the Three Months Ended September 30,				As of and for the Nine Months Ended September 30,
	2023		2022		2023		2022
Net loss attributable to Class A common stockholders	$	(19,122)	$	(10,707)	$	(39,607)	$	(13,300)

During the three and nine months ended September 30, 2023, the Company issued and sold 1,385,623 shares of Class A common stock for the gross and net proceeds of $8,337 and $7,867, respectively, with no such sales for the same periods in the prior year.

4.Warrant Liabilities

As of September 30, 2023, the Company had 9,558,701 Public Warrants and 8,900,000 Private Placement Warrants outstanding, while at December 31, 2022 the Company had 9,558,703 Public Warrants and 8,900,000 Private Placement Warrants outstanding.

NuScale Power Corporation

Notes to the Unaudited Condensed Consolidated Financial Statements

(in thousands, except shares and per share amounts)

Warrants may only be exercised for a whole number of shares. No fractional shares will be issued upon exercise of the Warrants. The Warrants are currently exercisable and will expire five years from the date of the Transaction or earlier upon redemption or liquidation.

Redemption of Warrants when the price per share of Class A common stock equals or exceeds $18.00. The Company may redeem the outstanding Warrants (except as described with respect to the Private Placement Warrants):

•in whole and not in part;

•at a price of $0.01 per Warrant;

•upon a minimum of 30 days prior written notice of redemption to each Warrant holder; and

•if the closing price of the Class A common stock equals or exceeds $18.00 per share (as adjusted) for any 20 trading days within a 30-trading day period ending three trading days before the Company sends the notice of redemption to the Warrant holders.

If and when the Warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

Redemption of Warrants when the price per share of Class A common stock equals or exceeds $10.00. The Company may redeem the outstanding Warrants:

•in whole and not in part;

•at $0.10 per Warrant upon a minimum of 30 days prior written notice of redemption provided that holders will be able to exercise their Warrants on a cashless basis prior to redemption and receive that number of shares determined based on the redemption date and the fair market value of the Class A common stock;

•if, and only if, the closing price of the Class A common stock equals or exceeds $10.00 per public share (as adjusted) for any 20 trading days within the 30-trading day period ending three trading days before the Company sends the notice of redemption to the Warrant holders; and

•if the closing price of the Class A common stock for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the Warrant holders is less than $18.00 per share (as adjusted), the Private Placement Warrants must also be concurrently called for redemption on the same terms as the outstanding Public Warrants.

If the Company calls the Public Warrants for redemption, as described above, the exercise price and number of ordinary shares issuable upon exercise of the Public Warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation.

Beginning on the 30th day following the Transaction, the Private Placement Warrants became almost identical to the Public Warrants sold in the Spring Valley Initial Public Offering. Additionally, the Private Placement Warrants are exercisable on a cashless basis and are non-redeemable, except as described above, so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

5.Fair Value Measurement

The Company measures certain financial assets and liabilities at fair value. Fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company uses a three-level hierarchy, which prioritizes fair value measurements based on the types of inputs used for the various valuation techniques (market approach, income approach and cost approach).

The levels of hierarchy are described below:

Level 1 Quoted prices in active markets for identical instruments;

NuScale Power Corporation

Notes to the Unaudited Condensed Consolidated Financial Statements

(in thousands, except shares and per share amounts)

Level 2 Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and

Level 3 Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Financial assets and liabilities are classified in their entirety based on the most stringent level of input that is significant to the fair value measurement.

The carrying amount of certain financial instruments, including deposits, accounts payable and accrued expenses, approximates fair value due to their short maturities.

Our Warrants are accounted for as liabilities pursuant to ASC 815-40 and are measured at fair value as of each reporting period. Changes in fair value of the Warrants are recorded in the statement of operations each period. Due to the similarity of the features of the Public and Private Warrants, management has concluded that the price of the Public Warrants would be used in the valuation of the Private Placement Warrants. However, since the two types of Warrants are not identical and the Private Warrants are not actively traded, we have classified the Private Placement Warrants as Level 2, while the Public Warrants are classified as Level 1.

The following tables represents the Company’s financial liabilities measured at fair value on a recurring basis:



(in thousands)	Level 1		Level 2		Level 3		Total
Warrant Liabilities:
Public Warrants	$	6,309	$	—	$	—	$	6,309
Private Placement Warrants	—		5,874		—		5,874

Total Warrant Liabilities as of December 31, 2022	$	15,198	14,151	—	$	29,349

6.Accounts and Other Receivables

Accounts and other receivables include reimbursement requests outstanding from the sponsored cost share awards, interest receivable and commercial accounts receivable. The DOE reimbursement requests are recognized as eligible costs are incurred. Reimbursement under the awards is recognized as award funds are obligated, and are included in Sponsored cost share in the condensed consolidated statement of operations. Interest receivable of $676 and $1,021 was outstanding at September 30, 2023 and December 31, 2022, respectively.

The majority of our receivables are either due from the U.S. federal government or have to do with a federal project. For these reasons, all receivables are deemed to be fully collectible and no allowance has been recorded.

8.DCRA, LLM Agreement and Settlement and Release Agreement

During the first quarter of 2023, we entered into the LLM Agreement with CFPP LLC. Related to this contract, the Company has subcontracted for the purchase of certain long-lead materials in the amount of $55,700, that were to be used in fabrication of the NPMs as part of the DCRA with CFPP LLC. However, subsequent to September 30, 2023, NuScale and CFPP LLC entered into discussions, and ultimately agreed to terminate the DCRA and LLM Agreement, with additional wind down activity still to occur. As a result, the previously titled Long-term contract work in process is now identified as Long-lead material work in process on our condensed consolidated balance sheet in the amount of $30,765 as of September 30, 2023, while as of December 31, 2022 we had none.

Due to our negotiations and ultimate termination of the DCRA and LLM Agreement with CFPP LLC, as of September 30, 2023 it was probable that we would be required to reimburse CFPP LLC $34,500 for net development costs pursuant to the DCRA. This is included in CFPP liability on the condensed consolidated balance sheet and in Research and development expenses on the condensed consolidated statements of operations.

Subsequent to September 30, 2023, NuScale and CFPP LLC executed a Settlement and Release Agreement (“Release Agreement”) whereby we have agreed to pay $49,769 to CFPP LLC. NuScale and CFPP LLC are in the process of completing the wind down work and demobilization pursuant to the Release Agreement that will result in an additional payment being made to CFPP LLC based on the actual DOE eligible costs incurred by CFPP LLC through the award termination date. Once certain conditions have been met, the Release Agreement would terminate the DCRA and LLM Agreement between the two entities. We anticipate additional expense during the fourth quarter associated with the termination estimated between $11,000 and $16,000, inclusive of demobilization and other costs, for which we have a letter of credit in the amount of $5,000 that is collateralized by $5,100 of Restricted cash that will be used to pay demobilization costs if they are incurred. Once the final settlement payment has been made the remaining Restricted cash will be released to the Company.

9.Employee Benefits

The Company sponsors a defined contribution 401(k) Plan with contributions to be made at the sole discretion of management. Under the provisions of the 401(k) Plan, the Company matches the employees’ contributions for the first 3% of compensation and matches 50% of the employees’ contributions for the next 2% of compensation. The expense recorded for the 401(k) Plan was $578 and $592 for the three months ended September 30, 2023 and 2022, respectively, and $2,020 and $1,759 for the nine months ended September 30, 2023 and 2022, respectively.

10.Income Taxes

NuScale LLC was historically and remains a partnership for U.S. federal income tax purposes with each partner being separately taxed on its share of taxable income or loss. NuScale Corp is subject to U.S. federal income taxes, in

NuScale Power Corporation

Notes to the Unaudited Condensed Consolidated Financial Statements

(in thousands, except shares and per share amounts)

addition to state and local income taxes, with respect to its distributive share of any net taxable income or loss and any related tax credits of NuScale LLC.

The effective tax rate was 0% for the three and nine months ended September 30, 2023. The effective income tax rate for the three and nine months ended September 30, 2023 differed significantly from the statutory rates, primarily due to the losses allocated to NCI and the recognition of a valuation allowance as a result of the Company’s new tax structure following the Transaction.

There was no income tax expense recorded during the three and nine months ended September 30, 2023.

The Company has assessed the realizability of the net deferred tax assets and in that analysis has considered the relevant positive and negative evidence available to determine whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The Company has recorded a full valuation allowance against the deferred tax assets at NuScale Corp as of September 30, 2023, which will be maintained until there is sufficient evidence to support the reversal of all or some portion of these allowances.

The Company’s income tax filings will be subject to audit by various taxing jurisdictions. The Company will monitor the status of U.S. federal, state and local income tax returns that may be subject to audit in future periods. No U.S. federal, state and local income tax returns are currently under examination by the respective taxing authorities.

In August 2022, the Inflation Reduction Act, or IRA, was enacted which includes the following key summary provisions: (i) a 15% Corporate Alternative Minimum Tax, or CAMT, that allows an offset of up to 75% with existing tax credit carryforwards, (ii) excise tax applicable to certain stock repurchases including ordinary buy backs and open market repurchases, (iii) extension and expansion of clean energy credits and incentives, and (iv) indefinite carryover of the CAMT. This legislation also provides transferability opportunities for certain newly generated credits as well as a direct pay option. For the three and nine months ended September 30, 2023, the enactment of the IRA did not result in any material adjustment to our income tax provision.

11.Equity-Based Compensation

The total compensation expense recognized for common share options and time-based RSU awards during the three months ended September 30, 2023 and 2022 was $4,009 and $5,075, respectively, and $12,099 and $7,207 for the nine months ended September 30, 2023 and 2022, respectively. For the three months ended September 30, 2023, equity-based compensation of $1,496 was included in G&A expense and $2,513 was included in Other expense, compared to $3,017 and $2,058, respectively, over the same period in the prior year. For the nine months ended September 30, 2023, equity-based compensation of $4,857 was included in G&A expense and $7,242 included in Other expense compared to $3,860 and $3,347, respectively, over the same period in the prior year.

Effective January 1, 2023, the share pool was automatically increased by 8,972,128, which is the number of shares of Class A common stock equal to four percent (4%) of the aggregate number of shares of Class A common stock and Class B common stock outstanding on December 31, 2022, excluding any such outstanding shares of Class A common

stock that were granted under the 2022 long-term incentive plan and remain unvested and subject to forfeiture as of December 31, 2022.

The Company measures the fair value of each share option grant at the date of grant using a Black-Scholes option pricing model.

During the three months ended September 30, 2023, the Company granted to employees 358,644 RSUs with an aggregate value of $2,295 that vest one-third annually starting in August 2024, while for the nine months ended September 30, 2023, 2,193,660 RSUs were granted, with an aggregate value of $21,287, that vest one-third annually starting in February 2024. In addition, during the nine months ended September 30, 2023, the Company granted to directors 126,158 RSUs with an aggregate value of $1,068, that vest quarterly and will be fully vested in May 2024.

Finally, employee and director RSUs totaling 68,542 and 712,218 vested during the three and nine months ended September 30, 2023, respectively.

12.Related Party Transactions

From time to time, the Company enters into strategic agreements with Fluor, whereby Fluor or the Company perform services for one another.

13.Commitments and Contingencies

In the regular course of business, the Company is involved in various legal proceedings and claims incidental to the normal course of business. Other than as disclosed immediately below, the Company does not believe that any legal claims are material to the Company. Management does not believe that resolution of any of these matters will materially affect the Company’s financial position or results of operations.

On September 19, 2022, thirteen purported members of NuScale LLC filed suit in the U.S. District Court for the District of Oregon against NuScale LLC, Fluor Enterprises, Japan NuScale Innovation, Inc., and Sargent & Lundy Holdings, LLC. The plaintiffs purport to represent a class of individuals who held common units or options to purchase common units in NuScale LLC and seek declaratory relief and damages based on breach of contract and other common law claims. The claims are based on amendments to the operating agreement of NuScale LLC in connection with the Merger between NuScale LLC and Spring Valley Acquisition Corp. Plaintiffs claim, among other things, that such amendments breached NuScale LLC’s 5th Amended and Restated Operating Agreement and required the consent of holders of common units in NuScale LLC voting as a separate class. NuScale LLC filed a motion to dismiss the complaint on November 21, 2022. Plaintiffs filed a response on January 17, 2023, and NuScale LLC filed a reply on February 14, 2023. A hearing on various motions to dismiss took place on May 17, 2023, and on August 3, 2023, the Court issued a report and recommendation that recommended that NuScale LLC’s motion to dismiss be denied. On August 17, 2023, NuScale LLC filed an objection to the report and recommendation. The objection will be heard by the assigned District Court judge. While no assurance can be given as to the ultimate outcome of this matter, the Company does not believe it is probable that a loss will be incurred and the Company has not recorded any liability as a result of these actions.

In conjunction with DOE Office of Nuclear Energy Award DE-NE0008935 with UAMPS’ wholly owned subsidiary, CFPP LLC, the Company entered into a DCRA, under which it is developing the NRC license application and performing other site licensing and development activities. Under the DCRA, the Company may be obligated to reimburse to UAMPS a percentage of its net development costs up to a specified cap, which varies based on the stage of project development, if certain performance criteria are not met. While there has been no failure to satisfy performance criteria, NuScale and CFPP LLC have mutually agreed to terminate the DCRA and LLM Agreement as a result of the project being unable to attract sufficient committed subscribers.

Item 2. 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 Corporation (“NuScale Corp”) should be read together with our financial statements as of and for the years ended December 31, 2022 and 2021 and our unaudited interim condensed consolidated financial statements as of and for the three and nine months ended September 30, 2023 and 2022, together with related notes thereto. 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. Unless the context otherwise requires, references in this section to “NuScale LLC,” “us,” “our” or “we” refer to NuScale Power, LLC prior to the Transaction, and to NuScale Power Corporation (“NuScale Corp”) following the consummation of the Transaction.

Overview

Our mission is to provide scalable advanced nuclear technology to produce 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 small modular reactor (“SMR”), known as NuScale Power Module (“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 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 U.S. Nuclear Regulatory Commission (“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 Standard Design Approval (“SDA”) of our NPM and scalable plant design. With this phase of our DCA now complete, customers may proceed with plans to develop the Company’s 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 flow to grow until the commercialization of the NPM. On January 19, 2023, the NRC published in the Federal Register a final rule that certifies NuScale’s 12-unit 50 MWe SMR design for use in the United States, which became effective 30 days after publication.

In January 2023, the Company submitted a Standard Design Approval (SDA) Application and the associated licensing topical reports to the NRC for a NuScale’s 6-unit 77 MWe NPM design. Once approved, customers in the United States will be able to reference the certified design and SDA for expedited construction and operating licensing of NuScale’s SMR pursuant to 10 CFR Part 52. On July 31, 2023, the NRC formally announced that it has accepted the Company’s SDA Application for formal review. Based on the NRC’s published schedule for SDA Application review, we expect the NRC will complete its review and SDA approval to be received in approximately 21 months.

Merger with Spring Valley

In December 2021, NuScale LLC entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Spring Valley Acquisition Corp. (“Spring Valley”) and Spring Valley Merger Sub, LLC (“Merger Sub”), a wholly owned subsidiary of Spring Valley. Pursuant to the Merger Agreement, Merger Sub merged with and into NuScale LLC (the “Merger”), with NuScale LLC surviving the Merger (the “Surviving Company”), Spring Valley being renamed NuScale Corp, and NuScale LLC continuing to be held as a wholly controlled subsidiary of NuScale Power Corporation in an “Up-C” structure. On May 2, 2022, the transactions contemplated by the Merger Agreement, including the Merger (collectively the “Transaction”) were completed.

The Transaction is shown as a reverse recapitalization under 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 NuScale Corp (f/k/a Spring Valley) is the parent company, GAAP dictates that the financial statements of NuScale Corp represent a continuation of NuScale LLC’s operations, with the Transaction 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 Transaction. The consummation of

the Transaction resulted in NuScale LLC receiving cash equal to $341.5 million and assuming Warrant liabilities valued at $47.5 million.

Comparison of the Three Months Ended September 30, 2023 and 2022

Revenue

The increase in revenue is attributable to activities in support of the CFPP, as well as nuclear technologies consulting services.

Research and Development

R&D expenses increased due to a $34.5 million charge for reimbursable net development costs due to the CFPP LLC. This increase was partially offset by $3.6 million in lower professional fees related to a budgeted reduction in the DOE award and $2.5 million in compensation costs savings.

General and Administrative

While G&A expenses remained approximately the same, the three months ended September 30, 2023 included $3.7 million in higher costs related to the sales and marketing agreements, that was offset by lower professional fees, compensation costs and insurance.

Other

Other expenses decreased primarily due to lower compensation costs, partially offset by higher hardware and software costs.

Sponsored Cost Share

Sponsored cost share decreased due to a lower share percentage and funding from the DOE, which was partially offset by increases in USTDA and subrecipient cost share as other projects scale up.

Change in Fair Value of Warrant Liabilities

The Company’s warrant price has significantly decreased during the nine months ended September 30, 2023, while the warrant price only slightly decreased during the period from the date of the Transaction through September 30, 2022.

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.

On August 9, 2023, NuScale entered into a Sales Agreement with Cowen and Company, LLC, B. Riley Securities, Inc. and Canaccord Genuity LLC as sales agents under which the Company may offer and sell shares of the Company’s Class A common stock, having an aggregate sales price of up to $150.0 million from time to time through the sales agents (“ATM Program”). During the three and nine months ended September 30, 2023, the Company issued and sold 1,385,623 shares of Class A common stock at a weighted average price of $6.02 per share, generating gross and net proceeds of $8.3 million and $7.9 million, respectively. The aggregate compensation paid to the sales agent in connection with the sales was $0.3 million during the three months ended September 30, 2023. As of September 30, 2023, $141.7 million of Class A common stock remained eligible for sale under the ATM Program.

We had $117.5 million in cash and cash equivalents as of September 30, 2023, compared to $217.7 million as of December 31, 2022, and no debt on either date. Since inception, we have incurred significant operating losses; we have had negative operating cash flow during the nine months ended September 30, 2023 and 2022 and we have an accumulated deficit of $221.7 million as of September 30, 2023. Management expects that operating losses and negative cash flows to continue as we continue the development of technology and the development of market and strategic relationships with other companies in our transition to commercialization of our technologies.

Subsequent to September 30, 2023, NuScale and CFPP LLC executed a Settlement and Release Agreement (“Release Agreement”) whereby we have agreed to pay $49.8 million to CFPP LLC. NuScale and CFPP LLC are in the process of

completing the wind down work and demobilization pursuant to the Release Agreement that will result in an additional payment being made to CFPP LLC based on the actual DOE eligible costs incurred by CFPP LLC through the award termination date. Once certain conditions have been met, the Release Agreement would terminate the DCRA and LLM Agreement between the two entities. We anticipate additional expense during the fourth quarter associated with the termination estimated between $11.0 million and $16.0 million, inclusive of demobilization and other costs, for which we have a letter of credit in the amount of $5.0 million that is collateralized by $5.1 million of Restricted cash that will be used to pay demobilization costs if they are incurred. NuScale expects that approximately $24.3 million will be released from Restricted cash in the near term with a final accounting for settlement costs once the final settlement payment has been made.

To date, we have not generated material revenue. We do not expect to generate any meaningful revenue unless and until we commercialize our NPM and related services. While we expect R&D expenditures to decrease, we expect our G&A and Other costs to remain relatively flat in connection with the advancement of our products and services toward commercialization with new customers. While we believe we have sufficient funds to reach commercialization of our NPM, certain costs are not reasonably estimable at this time, and we may require additional funding. Our projections anticipate certain customer-sourced income that is not assured and DOE funds that are granted under the cooperative agreement secured by the Company, which are subject to Congressional appropriations and dependent on the President signing it into law.

We believe that based on our current level of operating expenses and currently available cash resources, we will have sufficient funds available to cover required R&D activities and operating cash needs for the next twelve months. However, considering that we have not yet completed the development of a commercial product and have no meaningful revenue to date, we may require additional funds. 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 a registration statement on Form S-3. Such sales may negatively affect the market price of our shares of Class A common stock. In particular, a large sale by Fluor, our majority shareholder, could significantly affect our stock price. We believe the likelihood that Warrant holders will exercise their Warrants depends on the trading price of our shares of Class A common stock which, from time to time, has exceeded the $11.50 Warrant exercise price. In certain circumstances, the Warrants can be exercised on a cashless basis. Our ability to fund R&D activities and our operating cash needs for the next twelve months does not depend on the proceeds we may receive as the result of exercises of Warrants.

Comparison of Cash Flows for the Nine Months Ended September 30, 2023 and 2022

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


	Nine Months Ended September 30,
(in thousands)	2023		2022
Net cash used in operating activities	$	(110,042)	$	(104,728)
Net cash provided by (used in) investing activities	48,326		(51,744)
Net cash provided by financing activities	14,133		366,886
Net (decrease) increase in cash and cash equivalents (A)	$	(47,583)	$	210,414

(A) Includes $79,164 in restricted cash

Cash Flows used in Operating Activities

During the nine months ended September 30, 2023, our cash flows used in operating activities were higher due to payments made under our sales and marketing agreements.

Cash Flows provided by (used in) Investing Activities

During the nine months ended September 30, 2023 and 2022, the majority of the change related to the Company’s sale and purchase of a short-term investment in the amount of $50.0 million. Typically, investing activities will consist of capital expenditures.

Cash Flows from Financing Activities

During the nine months ended September 30, 2023, net cash provided by financing activities primarily consisted of proceeds from the exercise of stock options and issuance of Class A common stock, while the nine months ended September 30, 2022 represent proceeds from the exercise of stock options, as well as funds received in association with the Transaction.

Capital Resources

Under the DCRA, the Company was required to have credit support to fund the amount of its potential reimbursement of these net development costs. In order to obtain a letter of credit for net development costs and a separate letter of credit for long-lead materials, the Company must segregate funds from the operating bank accounts as collateral. $79.2 million, identified as restricted cash on the accompanying condensed consolidated balance sheet, acts as collateral for the $77.6 million in letters of credit outstanding at September 30, 2023. These letters of credit are based on forecasted spend for net development costs and long-lead materials through end of the following quarter, when new letters of credit will be issued. We expect, in conjunction with the contract terminations, to obtain release of the letters of credit and restricted cash in exchange for payments of amounts to be agreed to with UAMPS in a settlement agreement (see the Liquidity section above for additional information regarding the Settlement and Release Agreement).

For information regarding risks related to the Release Agreement and winding down work on the Carbon Free Power Project, see the risk factor included in this Form 10-Q.

Recent Accounting Pronouncements

Management believes there is no new accounting guidance issued but not yet effective that would have a material impact to the Company’s current financial statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes from the discussion of the Company’s market risk in Part I, Item 7A., Quantitative and Qualitative Disclosures About Market Risk, of the Company’s 2022 Annual Report on Form 10-K.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the period ended September 30, 2023, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on this evaluation, our principal executive officer and principal financial officer have concluded that, as of the evaluation date, our disclosure controls and procedures were effective as of September 30, 2023. Accordingly, management believes that the financial statements included in this Form 10-Q present fairly in all material respects our financial position, results of operations and cash flows for the period presented.

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

Part II - Other Information

Item 1. Legal Proceedings

On September 19, 2022, thirteen purported members of NuScale LLC filed suit in the U.S. District Court for the District of Oregon against NuScale LLC, Fluor Enterprises, Japan NuScale Innovation, Inc., and Sargent & Lundy Holdings, LLC. The plaintiffs purport to represent a class of individuals who held common units or options to purchase common units in NuScale LLC and seek declaratory relief and damages based on breach of contract and other common law claims. The claims are based on amendments to the operating agreement of NuScale LLC in connection with the Merger between NuScale LLC and Spring Valley Acquisition Corp. Plaintiffs claim, among other things, that such amendments breached NuScale LLC’s 5th Amended and Restated Operating Agreement and required the consent of holders of common units in NuScale LLC voting as a separate class. NuScale LLC filed a motion to dismiss the complaint on November 21, 2022. Plaintiffs filed a response on January 17, 2023, and NuScale LLC filed a reply on February 14, 2023. A hearing on various motions to dismiss took place on May 17, 2023, and on August 3, 2023, the Court issued a report and recommendation that recommended that NuScale LLC’s motion to dismiss be denied. On August 17, 2023, NuScale LLC filed an objection to the report and recommendation. The objection will be heard by the assigned District Court judge.. While no assurance can be given as to the ultimate outcome of this matter, the Company does not believe it is probable that a loss will be incurred and the Company has not recorded any liability as a result of these actions.

Item 1A. Risk Factors

In addition to the risk factors as disclosed in the 2022 Annual Report on Form 10-K, we have added or updated the descriptions of certain risks as follows:

Risks Related to Ownership of Our Shares of Class A Common Stock or Warrants

We are and may continue to be subject to short selling strategies.

Short selling is the practice of selling securities that the seller has borrowed from a third party with the intention of buying identical securities at a later date, at a lower price, to return to the lender and the short seller profits. Because it is in the short seller’s best interests for the price of the stock to decline, a short seller of our Class A Common Stock may publish negative opinions regarding NuScale and our business prospects to cause our stock price to decline and to generate profits for the short seller. On October 19, 2023, Iceberg Research published such a report and disclosed it was short NuScale. After the report was published, our stock price declined from a close of $5.04 on October 18, 2023 to a close of $3.07 on October 30, 2023.

We may be subject to similar short strategies in the future, which could negatively affect our stock price. Our stock price may be particularly susceptible to material fluctuation when short strategies are implemented to the extent that we have limited trading volumes. State and federal regulators have traditionally been unable or unwilling to pursue actions against short sellers. If we disagree with a short seller’s opinions or dispute the underlying facts on which they purport to base their opinion, our recourse against the short seller may be limited.

Sales of a substantial number of shares of our Class A Common Stock in the public market could cause our stock price to fall.

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 shares of Class A Common Stock. On August 9, 2023, we entered into a sales agreement (Sales Agreement) with Cowen and Company, LLC, B. Riley Securities, Inc. and Canaccord Genuity LLC (collectively, “sales agents”) relating to shares of our Class A Common Stock offered from time to time “at the market.” In accordance with the terms of the Sales Agreement, we may offer and sell shares of our Class A Common Stock having an aggregate offering price of up to $150,000,000 from time to time through or to each selling agent acting as our agent or principal. As of September 30, 2023, we had sold 1,385,623 shares of Class A common stock at a weighted average price of $6.02 per share, for a gross and net price of $8.3 million and $7.9 million, respectively.

Subject to certain limitations in the Sales Agreement and compliance with applicable law, we have the discretion to deliver a placement notice to the sales agents at any time throughout the term of the Sales Agreement. The number of shares that are sold by a sales agent after we deliver a placement notice will fluctuate based on the market price of the Class A Common Stock during the sales period and limits we set. Because the price per share of each share sold will fluctuate based on the market price of our Class A Common Stock during the sales period, it is not possible at this time to predict the number of shares that will be ultimately issued.

As of September 30, 2023, there were (i) 76,416,658 shares of Class A Common Stock outstanding, (ii) 154,556,518 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) 54,026,598 shares of Class A Common Stock issuable upon the exercise of outstanding stock options and warrants.

Outstanding warrants to purchase an aggregate of 18,458,701 shares of Class A Common Stock are exercisable in accordance with the terms of the warrant agreement governing those securities. The exercise price of these warrants is $11.50 per share. In addition, outstanding options are exercisable in exchange for an aggregate of 9,606,510 shares of Class A Common Stock at a weighted-average exercise price of $4.20. 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.

Risks Related to NuScale’s Business and Industry

Commercialization Risk Factors

Amounts we have agreed to pay to CFPP LLC under the Settlement and Release Agreement are significant, and the loss of CFPP LLC as a customer may negatively affect perceptions of our business or our ability to commercialize our SMRs or our ability to raise capital for operations or development needs.

Under the Settlement and Release Agreement we signed with CFPP LLC, we have agreed to pay $49,769 to CFPP LLC, subject to adjustment once we determine the final Net Development Costs reimbursable to CFPP LLC. The settlement amount is significant and, in addition to potential upward adjustments in the reimbursement amount, we may incur additional expenses relating to winding down work on the Carbon Free Power Project. Although we expect the payments to be less than the amount of restricted cash we held at September 30, 2023 to secure our reimbursement obligations, these payments will materially and adversely affect our financial condition. In addition, the loss of CFPP LLC as a customer may negatively affect our prospects or the perception of our business or our ability to commercialize our SMRs. This could affect our ability to raise additional funds to finance our operations and our research and development activities.

When we reimburse costs and terminate the LLM Agreement, we are entitled to the long-lead materials purchased under the LLM Agreement; however, the value of the long-lead materials may be significantly lower than reimbursement costs related to the LLM Agreement, and we may have to pay costs to DOE (in addition to the refund to CFPP, LLC) to obtain the long-lead materials free of liens from DOE to use the long-lead materials for a project at the CFPP site or for another customer. There is no guarantee we will be able to use such materials in another project.

Nature of Business	Sep. 30, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business	Nature of Business Organization and Operations NuScale Power Corporation (“NuScale Corp”, the “Company”, “us”, “we” or “our”) is commercializing a modular, scalable 77 MWe (gross) light water reactor nuclear power plant using exclusive rights to a nuclear power plant design obtained from Oregon State University. The Company is majority owned by Fluor. Merger with Spring Valley In December 2021, NuScale LLC entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Spring Valley Acquisition Corp. (“Spring Valley”) and Spring Valley Merger Sub, LLC (“Merger Sub”), a wholly owned subsidiary of Spring Valley. Pursuant to the Merger Agreement, Merger Sub merged with and into NuScale LLC (the “Merger”), with NuScale LLC surviving the Merger (the “Surviving Company”), Spring Valley being renamed NuScale Corp, and NuScale LLC continuing to be held as a wholly controlled subsidiary of NuScale Power Corporation in an “Up-C” structure. On May 2, 2022, the Merger Agreement and Merger (collectively the “Transaction”) was completed. The Transaction is shown as a reverse recapitalization under United States Generally Accepted Accounting Principles (“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 NuScale Corp (f/k/a Spring Valley) is the parent company, GAAP dictates that the financial statements of NuScale Corp represent a continuation of NuScale LLC’s operations, with the Transaction 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 Transaction. The consummation of the Transaction resulted in NuScale LLC receiving cash equal to $341.5 million and assuming Warrant liabilities valued at $47.5 million.


1.			I have reviewed this quarterly report on Form 10-Q of NuScale Power Corporation;

2.			Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this report;

3.			Based on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects the financial condition, results of operations and cash flows of the registrant as of, and for, the periods presented in this report;

4.			The registrant’s other certifying officer(s) and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:


			(a)			All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the registrant’s ability to record, process, summarize and report financial information; and

			(b)			Any fraud, whether or not material, that involves management or other employees who have a significant role in the registrant’s internal control over financial reporting.


			(1)			The Report fully complies with the requirements of Section 13(a) or 15(d) of the Securities Exchange Act of 1934; and

			(2)			The information contained in the Report fairly presents, in all material respects, the financial condition and results of operations of the Company.

Summary of Significant Accounting Policies	Sep. 30, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The Company’s unaudited condensed consolidated financial statements and related notes do not include notes and certain financial information normally presented annually under GAAP, and therefore should be read in conjunction with our 2022 Annual Report on Form 10-K. Accounting measures at interim dates inherently involve greater reliance on estimates than at year-end. Although such estimates are based on management’s most recent assessment of the underlying facts and circumstances utilizing the most current information available, our reported results of operations may not necessarily be indicative of results that we expect for the full year. These financial statements are unaudited. In management’s opinion, they contain all adjustments of a normal recurring nature which are necessary to present fairly our financial position and our operating results as of and for the interim periods presented. Principles of Consolidation As part of the Transaction, NuScale Corp has been determined to be the primary beneficiary of NuScale LLC, a variable interest entity (“VIE”). As the sole managing member of NuScale LLC, NuScale Corp has both the power to direct the activities, and direct ownership to share in the revenues and expenses of NuScale LLC. As such, all the activity of NuScale LLC has been consolidated in the accompanying condensed consolidated financial statements. All assets and liabilities included in the balance sheet are that of NuScale LLC, other than the NuScale Corp Warrants and certain prepaid insurance. All significant intercompany transactions have been eliminated upon consolidation. Changes in Presentation For the three and nine months ended September 30, 2022, amounts totaling $39 and $154, respectively, were previously included in Interest income (expense) and have been reclassified to Sponsored cost share to conform to the current year presentation on the accompanying condensed consolidated statements of operations. No such reclassifications were required for the 2023 fiscal year. For the three months ended September 30, 2022, amounts totaling $987 and $1,001 were reclassified out of G&A expenses and into R&D expenses and Other expenses, respectively, to conform to the current year presentation. During the nine months ended September 30, 2023, R&D expenses totaling $1,855 were reclassified to Other expenses to conform to the current year presentation, while for the nine months ended September 30, 2022, $2,348 and $3,115 have been reclassified out of G&A expenses and into R&D expenses and Other expenses, respectively, to conform to the current year presentation. Cash, Cash Equivalents and Restricted Cash Cash equivalents represent short-term, highly liquid investments, which are readily convertible to cash and have maturities of three months or less at time of purchase. Cash equivalents with an initial maturity of between three and twelve months at time of purchase are presented as short-term investments on the accompanying condensed consolidated balance sheet. Cash equivalents and Short-term investments consist of certificates of deposit. These certificates of deposit are classified as held-to-maturity, and the estimated fair value of the investment approximates its amortized cost. Cash in the amount of $79,164 was restricted as collateral for the letter of credit associated with the Development Cost Reimbursement Agreement (“DCRA”) at September 30, 2023 (See Note 13). The DCRA spans multiple years requiring the amount to be classified as a noncurrent asset, included in Restricted cash in the accompanying condensed consolidated balance sheet. The restricted cash balance plus Cash and cash equivalents on the accompanying condensed consolidated balance sheet equals cash, cash equivalents and restricted cash, as reflected in the accompanying condensed consolidated statements of cash flows. Sales and Marketing Agreements The Company has entered into sales and marketing agreements pursuant to which it prepaid certain expenses to the counterparty. As of September 30, 2023, the current portion of $16,200 and noncurrent portion of $3,750, are included in Prepaid expenses and Other assets, respectively, on the accompanying condensed consolidated balance sheet and will be amortized monthly on a straight line basis through the period ended December 31, 2024. Warrant Liability The Company accounts for the Warrants in accordance with the guidance contained in Accounting Standards Codification (“ASC”) 815, “Derivatives and Hedging”, under which the Warrants do not meet the criteria for equity treatment and must be recorded as liabilities. Accordingly, the Company classifies the Warrants as liabilities at their fair value and adjusts the Warrants to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s condensed consolidated statements of operations. The fair value of the Public and Private Placement Warrants has been estimated using the Public Warrants’ quoted market price. See note 4 for further discussion of the terms of the Warrants and note 5 for further discussion of the methodology used to determine the value of the Warrants. Sponsored Cost Share As our commercialization activities advance, we have continued to enter into cost share agreements with various entities, including both governmental and private, under which the Company is reimbursed for specific R&D activities. As of September 30, 2023, these entities include the DOE, United States Department of State and United States Trade and Development Agency (combined as “USG”), CFPP LLC and RoPower Nuclear S.A. Since 2014, the DOE has provided critical funding to the Company through a series of cooperative agreements that support ongoing commercialization activities. During the three months ended September 30, 2023 and 2022, DOE cost share totaled $9,171 and $18,382, respectively, while for the nine months ended September 30, 2023 and 2022, DOE cost share totaled $28,718 and $64,016, respectively. Beginning in 2021, the Company partnered with USG to develop SMRs in foreign markets. Under USG’s technical assistance grant programs, we receive cost share commitments to support licensing work in these foreign markets, one of which is additionally supported by RoPower Nuclear S.A. During the three months ended September 30, 2023 and 2022, USG cost share totaled $10,521 and $39, respectively, while during the nine months ended September 30, 2023 and 2022, USG cost share totaled $20,080 and $154, respectively. Finally, we received subrecipient cost share from CFPP LLC under a contract between the DOE and UAMPS for R&D performed with the goal of developing our first SMR. Under this agreement we received cost share of $1,082 and $6,186 during the three and nine months ended September 30, 2023, with no cost share during the same periods in the prior year. We have agreed to terminate our agreements with CFPP LLC (see Note 8).

Warrant Liabilities	Sep. 30, 2023
Warrants and Rights Note Disclosure [Abstract]
Warrant Liabilities	Warrant LiabilitiesAs of September 30, 2023, the Company had 9,558,701 Public Warrants and 8,900,000 Private Placement Warrants outstanding, while at December 31, 2022 the Company had 9,558,703 Public Warrants and 8,900,000 Private Placement Warrants outstanding. Warrants may only be exercised for a whole number of shares. No fractional shares will be issued upon exercise of the Warrants. The Warrants are currently exercisable and will expire five years from the date of the Transaction or earlier upon redemption or liquidation. Redemption of Warrants when the price per share of Class A common stock equals or exceeds $18.00. The Company may redeem the outstanding Warrants (except as described with respect to the Private Placement Warrants): •in whole and not in part; •at a price of $0.01 per Warrant; •upon a minimum of 30 days prior written notice of redemption to each Warrant holder; and •if the closing price of the Class A common stock equals or exceeds $18.00 per share (as adjusted) for any 20 trading days within a 30-trading day period ending three trading days before the Company sends the notice of redemption to the Warrant holders. If and when the Warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of Warrants when the price per share of Class A common stock equals or exceeds $10.00. The Company may redeem the outstanding Warrants: •in whole and not in part; •at $0.10 per Warrant upon a minimum of 30 days prior written notice of redemption provided that holders will be able to exercise their Warrants on a cashless basis prior to redemption and receive that number of shares determined based on the redemption date and the fair market value of the Class A common stock; •if, and only if, the closing price of the Class A common stock equals or exceeds $10.00 per public share (as adjusted) for any 20 trading days within the 30-trading day period ending three trading days before the Company sends the notice of redemption to the Warrant holders; and •if the closing price of the Class A common stock for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the Warrant holders is less than $18.00 per share (as adjusted), the Private Placement Warrants must also be concurrently called for redemption on the same terms as the outstanding Public Warrants. If the Company calls the Public Warrants for redemption, as described above, the exercise price and number of ordinary shares issuable upon exercise of the Public Warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation. Beginning on the 30th day following the Transaction, the Private Placement Warrants became almost identical to the Public Warrants sold in the Spring Valley Initial Public Offering. Additionally, the Private Placement Warrants are exercisable on a cashless basis and are non-redeemable, except as described above, so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

Receivables [Abstract]
Accounts and Other Receivables	Accounts and Other Receivables Accounts and other receivables include reimbursement requests outstanding from the sponsored cost share awards, interest receivable and commercial accounts receivable. The DOE reimbursement requests are recognized as eligible costs are incurred. Reimbursement under the awards is recognized as award funds are obligated, and are included in Sponsored cost share in the condensed consolidated statement of operations. Interest receivable of $676 and $1,021 was outstanding at September 30, 2023 and December 31, 2022, respectively. The majority of our receivables are either due from the U.S. federal government or have to do with a federal project. For these reasons, all receivables are deemed to be fully collectible and no allowance has been recorded.

Inventory Disclosure [Abstract]
DCRA, LLM Agreement and Settlement and Release Agreement	DCRA, LLM Agreement and Settlement and Release AgreementDuring the first quarter of 2023, we entered into the LLM Agreement with CFPP LLC. Related to this contract, the Company has subcontracted for the purchase of certain long-lead materials in the amount of $55,700, that were to be used in fabrication of the NPMs as part of the DCRA with CFPP LLC. However, subsequent to September 30, 2023, NuScale and CFPP LLC entered into discussions, and ultimately agreed to terminate the DCRA and LLM Agreement, with additional wind down activity still to occur. As a result, the previously titled Long-term contract work in process is now identified as Long-lead material work in process on our condensed consolidated balance sheet in the amount of $30,765 as of September 30, 2023, while as of December 31, 2022 we had none. Due to our negotiations and ultimate termination of the DCRA and LLM Agreement with CFPP LLC, as of September 30, 2023 it was probable that we would be required to reimburse CFPP LLC $34,500 for net development costs pursuant to the DCRA. This is included in CFPP liability on the condensed consolidated balance sheet and in Research and development expenses on the condensed consolidated statements of operations.

Income Taxes	9 Months Ended
Income Taxes	Sep. 30, 2023
Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesNuScale LLC was historically and remains a partnership for U.S. federal income tax purposes with each partner being separately taxed on its share of taxable income or loss. NuScale Corp is subject to U.S. federal income taxes, in addition to state and local income taxes, with respect to its distributive share of any net taxable income or loss and any related tax credits of NuScale LLC. The effective tax rate was 0% for the three and nine months ended September 30, 2023. The effective income tax rate for the three and nine months ended September 30, 2023 differed significantly from the statutory rates, primarily due to the losses allocated to NCI and the recognition of a valuation allowance as a result of the Company’s new tax structure following the Transaction. There was no income tax expense recorded during the three and nine months ended September 30, 2023. The Company has assessed the realizability of the net deferred tax assets and in that analysis has considered the relevant positive and negative evidence available to determine whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The Company has recorded a full valuation allowance against the deferred tax assets at NuScale Corp as of September 30, 2023, which will be maintained until there is sufficient evidence to support the reversal of all or some portion of these allowances. The Company’s income tax filings will be subject to audit by various taxing jurisdictions. The Company will monitor the status of U.S. federal, state and local income tax returns that may be subject to audit in future periods. No U.S. federal, state and local income tax returns are currently under examination by the respective taxing authorities. In August 2022, the Inflation Reduction Act, or IRA, was enacted which includes the following key summary provisions: (i) a 15% Corporate Alternative Minimum Tax, or CAMT, that allows an offset of up to 75% with existing tax credit carryforwards, (ii) excise tax applicable to certain stock repurchases including ordinary buy backs and open market repurchases, (iii) extension and expansion of clean energy credits and incentives, and (iv) indefinite carryover of the CAMT. This legislation also provides transferability opportunities for certain newly generated credits as well as a direct pay option. For the three and nine months ended September 30, 2023, the enactment of the IRA did not result in any material adjustment to our income tax provision.

Equity-Based Compensation	Equity-Based Compensation The total compensation expense recognized for common share options and time-based RSU awards during the three months ended September 30, 2023 and 2022 was $4,009 and $5,075, respectively, and $12,099 and $7,207 for the nine months ended September 30, 2023 and 2022, respectively. For the three months ended September 30, 2023, equity-based compensation of $1,496 was included in G&A expense and $2,513 was included in Other expense, compared to $3,017 and $2,058, respectively, over the same period in the prior year. For the nine months ended September 30, 2023, equity-based compensation of $4,857 was included in G&A expense and $7,242 included in Other expense compared to $3,860 and $3,347, respectively, over the same period in the prior year. Effective January 1, 2023, the share pool was automatically increased by 8,972,128, which is the number of shares of Class A common stock equal to four percent (4%) of the aggregate number of shares of Class A common stock and Class B common stock outstanding on December 31, 2022, excluding any such outstanding shares of Class A common stock that were granted under the 2022 long-term incentive plan and remain unvested and subject to forfeiture as of December 31, 2022. The Company measures the fair value of each share option grant at the date of grant using a Black-Scholes option pricing model. During the three months ended September 30, 2023, the Company granted to employees 358,644 RSUs with an aggregate value of $2,295 that vest one-third annually starting in August 2024, while for the nine months ended September 30, 2023, 2,193,660 RSUs were granted, with an aggregate value of $21,287, that vest one-third annually starting in February 2024. In addition, during the nine months ended September 30, 2023, the Company granted to directors 126,158 RSUs with an aggregate value of $1,068, that vest quarterly and will be fully vested in May 2024.

Commitments and Contingencies	9 Months Ended
Commitments and Contingencies	Sep. 30, 2023
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the regular course of business, the Company is involved in various legal proceedings and claims incidental to the normal course of business. Other than as disclosed immediately below, the Company does not believe that any legal claims are material to the Company. Management does not believe that resolution of any of these matters will materially affect the Company’s financial position or results of operations. On September 19, 2022, thirteen purported members of NuScale LLC filed suit in the U.S. District Court for the District of Oregon against NuScale LLC, Fluor Enterprises, Japan NuScale Innovation, Inc., and Sargent & Lundy Holdings, LLC. The plaintiffs purport to represent a class of individuals who held common units or options to purchase common units in NuScale LLC and seek declaratory relief and damages based on breach of contract and other common law claims. The claims are based on amendments to the operating agreement of NuScale LLC in connection with the Merger between NuScale LLC and Spring Valley Acquisition Corp. Plaintiffs claim, among other things, that such amendments breached NuScale LLC’s 5th Amended and Restated Operating Agreement and required the consent of holders of common units in NuScale LLC voting as a separate class. NuScale LLC filed a motion to dismiss the complaint on November 21, 2022. Plaintiffs filed a response on January 17, 2023, and NuScale LLC filed a reply on February 14, 2023. A hearing on various motions to dismiss took place on May 17, 2023, and on August 3, 2023, the Court issued a report and recommendation that recommended that NuScale LLC’s motion to dismiss be denied. On August 17, 2023, NuScale LLC filed an objection to the report and recommendation. The objection will be heard by the assigned District Court judge. While no assurance can be given as to the ultimate outcome of this matter, the Company does not believe it is probable that a loss will be incurred and the Company has not recorded any liability as a result of these actions. In conjunction with DOE Office of Nuclear Energy Award DE-NE0008935 with UAMPS’ wholly owned subsidiary, CFPP LLC, the Company entered into a DCRA, under which it is developing the NRC license application and performing other site licensing and development activities. Under the DCRA, the Company may be obligated to reimburse to UAMPS a percentage of its net development costs up to a specified cap, which varies based on the stage of project development, if certain performance criteria are not met. While there has been no failure to satisfy performance criteria, NuScale and CFPP LLC have mutually agreed to terminate the DCRA and LLM Agreement as a result of the project being unable to attract sufficient committed subscribers. Under the DCRA, the Company was required to have credit support to fund the amount of its potential reimbursement of these net development costs. In order to obtain a letter of credit for net development costs and a separate letter of credit for long-lead materials, the Company must segregate funds from the operating bank accounts as collateral, which is classified as restricted cash on the accompanying condensed consolidated balance sheet. As of September 30, 2023, the Company held $79,164 of restricted cash which acts as collateral for the $77,600 in letters of credit outstanding. The amount of these letters of credit are based on forecasted spend for net development costs and long- lead materials through end of the following quarter, when new letters of credit will be issued. In conjunction with the contract terminations, we will obtain a release of the letters of credit and restricted cash in exchange for payments of amounts as agreed upon with UAMPS in the settlement agreement (see Note 8 for additional information regarding the Settlement and Release Agreement).
