    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 7

CORPORATE GOVERNANCE

Notable features of NuScale’s corporate governance structure include:

•independent director representation on the Audit Committee;

•independent directors meet regularly in executive sessions without the presence of NuScale’s corporate officers or non-independent directors;

•at least one of NuScale’s directors will qualify as an “audit committee financial expert” as defined by the SEC; and

•other corporate governance best practices such as implementing a robust director education program.

Independence of the Board of Directors

The NYSE rules generally require that independent directors must comprise a majority of a listed company’s board of directors. As a controlled company, we are exempt from such requirements. Based upon information requested from and provided by each of our directors concerning his or her background, employment and affiliations, including family relationships, we have determined that Messrs. Kresa, Hackett, Fujino, and Chung, and Ms. Warnica are “independent” as that term is defined under the applicable rules and regulations of the SEC and the listing requirements and rules of the NYSE.

Role of Board in Risk Oversight

The Board has extensive involvement in the oversight of risk management related to NuScale and its business and accomplishes this oversight through the regular reporting to the Board by the Audit Committee. The Audit Committee periodically reviews NuScale’s accounting, reporting and financial practices, including the integrity of its financial statements, the surveillance of administrative and financial controls, its compliance with legal and regulatory requirements, and cybersecurity-related matters. Through its regular meetings with management, including the finance, legal, internal audit and information technology functions, the Audit Committee reviews and discusses all significant areas of NuScale’s business and summarizes for the Board key areas of financial risk and the appropriate mitigating factors. In addition, the Nomination and Governance Committee also has a role in reducing risk through the evaluation and choice of Board members who hold management accountable, oversees the firm’s integrity, charters and governance policies which guide the organization’s checks and balances, and approves delegations of authority. The Organization and Compensation Committee also has a role in risk management and mitigation by ensuring that the Company’s compensation philosophy and programs do not induce too much risk-taking by management and instead reward good stewardship of stockholder investments.

Board Committees

The standing committees of the Board include an Audit Committee, an Organization and Compensation Committee, a Nominating and Corporate Governance Committee, and an Executive Committee. The Board may from time to time establish other committees.

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 8

Our president and Chief Executive Officer (“CEO”) and other executive officers regularly report to the non-executive directors and the Audit, Organization and Compensation, and Nominating and Governance Committees to ensure effective and efficient oversight of our activities and to assist in proper risk management and the ongoing evaluation of management controls. We believe that the leadership structure of the Board provides appropriate risk oversight of NuScale’s activities in addition to the expertise from our controlling interests held by NuScale’s majority owner, Fluor Enterprises, Inc. and its affiliates including Fluor Corporation (“Fluor”), which is available to us, if needed.

Audit Committee

Our Audit Committee is composed of Messrs. Kresa (chair), Fujino, and Hackett, and Ms. Warnica. Each member of the Audit Committee is financially literate and qualifies as an independent director under the NYSE corporate governance standards and the independence requirements of Rule 10A-3 under the Securities Exchange Act of 1934 (the “Exchange Act”). Mr. Kresa qualifies as an “audit committee financial expert” as defined in Item 407(d)(5) of Regulation S-K and possesses financial sophistication, as defined under the rules of the NYSE.

The purpose of the Audit Committee is to prepare the audit committee report required by the SEC to be included in NuScale’s proxy statement and to assist the Board in overseeing and monitoring (1) the quality and integrity of the financial statements, (2) compliance with legal and regulatory requirements, (3) our independent registered public accounting firm’s qualifications, independence, and performance, and (4) the performance of our internal audit function. Among its other duties, the Audit Committee is charged with reviewing the adequacy and effectiveness of the Company’s internal controls, including computerized information system controls and cybersecurity. The Audit Committee also receives periodic reports on transactions with “related persons” under NuScale’s related person transaction policy and, if a new party or transaction is subject to the policy, determines whether or not to approve the transaction. There were seven meetings of the Audit Committee in 2023 and all members attended all meetings of that committee.

The Audit Committee has a written charter that is available on our website, www.nuscalepower.com. Information contained on or accessible through our website is not a part of this proxy statement.

Organization and Compensation Committee

Our Organization and Compensation Committee (“Compensation Committee”) is composed of Messrs. Hackett (chair), Boeckmann, Kresa and Breuer. The purpose of the Compensation Committee is to assist the Board in discharging its responsibilities relating to (1) setting our compensation program and the compensation of our executive officers and directors, (2) monitoring our incentive and equity-based compensation plans, and (3) if required, providing the Compensation Committee report required by SEC rules. Among its other responsibilities, the Compensation Committee oversees the Company's strategic employment and workplace policies, practices and outcomes, including those relating to equal employment opportunity, nondiscrimination, diversity in the workplace and environmental, health and safety policies. As discussed in the Director Compensation and Executive Compensation sections below, the Compensation Committee has retained a professional compensation consultant as its advisor. There were five meetings of the Organization and Compensation Committee in 2023, and all members attended all meetings of that committee.

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 9

Our Compensation Committee has a written charter that is available on our website, www.nuscalepower.com. Information contained on or accessible through our website is not a part of this proxy statement.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee is composed of Messrs. Collins (chair), Chung, Boeckmann, and Sorrells and Ms. Warnica. The purpose of the Nominating and Corporate Governance Committee is to assist the Board in discharging its responsibilities relating to (1) identifying individuals qualified to become new members of the Board, consistent with criteria approved by the Board, (2) reviewing the qualifications of incumbent directors to determine whether to recommend them for reelection and selecting, or recommending that the Board select, the director nominees for the next annual meeting of stockholders, (3) identifying potential members qualified to fill vacancies on any Board committee and recommending that the Board appoint the identified member or members to the applicable committee, (4) reviewing and recommending to the Board corporate governance principles applicable to NuScale, (5) overseeing the evaluation of the Board and management and (6) handling such other matters that are specifically delegated to the committee by the Board from time to time, such as the 2023 delegations of authority to management. There were two meetings of the Nominating and Corporate Governance Committee in 2023 and all members attended all meetings of that committee.

Our Nominating and Corporate Governance Committee has a written charter that is available on our website, www.nuscalepower.com. Information contained on or accessible through our website is not a part of this proxy statement. Pursuant to that charter, the Nominating and Corporate Governance Committee has developed and the Board has approved criteria to be considered in selecting nominees for Director. Candidates are selected for, among other things, their public company experience, their commercial acumen, and their satisfaction of criteria included in the rules of the NYSE and SEC regulations. NuScale is currently a controlled company, majority-owned by an affiliate of the Fluor Corporation. For future elections to the Board, while satisfying the foregoing director criteria serves as gating criteria for new candidates, the Nominating and Corporate Governance Committee has expressed a desire to consider diversity of race and sex in making future nominations to the NuScale Board. The Nominating and Corporate Governance Committee has not paid a consultant to assist it in identifying Board candidates. Aside from Mr. Breuer, who was recommended for appointment by Fluor, no stockholders have recommended candidates for appointment to the Company’s Board.

The Board understands the significant time commitment involved with serving on the Board and its committees. Under our Corporate Governance Guidelines, the Company’s Directors should limit their service as directors on public company boards and investment company boards to no more than four (including the Company's Board). Directors who are serving as executive officers of public companies may not serve on the boards of more than one other public company in addition to the Company’s Board. Directors must advise the Chair of the Governance Committee in advance of accepting an invitation to serve on another board. Based upon their current board commitments, all director nominees are currently in compliance with our Corporate Governance Guidelines regarding Director commitments. In determining to recommend each of the nominees for election at the annual meeting, the Governance Committee and

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 10

the Board evaluated and concluded that each of the nominees has demonstrated that they have committed and will continue to be able to commit the appropriate time to fulfill their duties and effectively serve on our Board and its committees.

Executive Committee

The Board has established an Executive Committee, comprised of the Board Chairman, NuScale’s CEO, and the Chairs of the three standing committees: Audit, Organization and Compensation, and Nominating and Corporate Governance. Mr. Hackett, as Board Chairman and Chair of a standing committee, Mr. Hopkins, as NuScale’s CEO, and Messrs. Kresa and Collins, as Chairs of the remaining standing committees, are the current members of the Executive Committee. Mr. Hackett serves as Executive Committee Chair. There were three meetings of the Executive Committee in 2023 and all members attended all meetings of that committee. Should a meeting of the Executive Committee be called when the Board is not in session, the Executive Committee has all of the power and authority of the Board, subject to applicable laws, rules, regulations and listing standards of the NYSE.

Compensation Committee Interlocks and Insider Participation

The members of our Compensation Committee are listed above under the heading “Organization and Compensation Committee”. No member of the Compensation Committee was at any time during fiscal year 2023, or at any other time, one of our officers or employees. None of our executive officers has served as a director or member of a compensation committee (or other committee serving an equivalent function) of any entity whose executive officers served as a director on our Board or member of our Compensation Committee.

Code of Business Conduct

We have a code of business conduct that applies to all of our directors, officers and employees, including our principal executive officer, principal financial officer and principal accounting officer. A copy of the code of conduct is available on our website at www.nuscalepower.com. The code of business conduct is a “code of ethics,” as defined in Item 406(b) of Regulation S-K.

Christine Thompson-Colbert

Christine Thompson-Colbert is a Related Person by virtue of being the spouse of Christopher Colbert, who served as an executive officer of the Company during the Company’s fiscal year ended December 31, 2023. On May 12, 2023, Mrs. Thompson-Colbert exchanged 75,585 NuScale LLC Class B Units and 75,585 shares of Class B Common Stock for 75,585 shares of Class A Common Stock pursuant to the provisions of the A&R NuScale LLC Agreement. For more information on exchange procedures and other aspects of the A&R NuScale LLC Agreement, see the discussion under the heading “A&R NuScale LLC Agreement” in Exhibit 4.5, “Description of Registrant’s Securities”, to the Company’s 2023 annual report on Form 10-K. Based on the closing price per share of Class A Common Stock on May 12, 2023 of $8.30, the Class A Common Stock issued to Mrs. Thompson-Colbert had an aggregate value of $627,355.50.

Tax Receivable Agreement

NuScale LLC and each of its direct or indirect (through subsidiaries that are classified as partnerships or disregarded entities for United States federal income tax purposes) subsidiaries that are classified as a partnership for United States federal income tax purposes have made an election under Section 754 of

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 13

the Internal Revenue Code of 1986, as amended (the “Code”) for the 2023 taxable year, and such election will remain in effect for any future taxable year in which an exchange of NuScale LLC Class B Units for shares of NuScale Class A Common Stock (“Class A Common Stock”) under the Sixth Amended and Restated Limited Liability Company Agreement of NuScale LLC (the “A&R NuScale LLC Agreement”) occurs. For a description of the A&R NuScale LLC Agreement, see the discussion under the heading “A&R NuScale LLC Agreement” in Exhibit 4.5, “Description of Registrant’s Securities,” to the Company’s 2023 annual report on Form 10-K. Such elections are expected to result in increases to the tax basis of the assets of NuScale LLC at the time of any future exchange of NuScale LLC Class B Units for shares of Class A Common Stock under the A&R NuScale LLC Agreement. Such increases in the tax basis of the tangible and intangible assets of NuScale LLC, as well as other tax benefits, may reduce the amount of tax that NuScale would otherwise be required to pay in the future. Such increases in tax basis and other tax benefits may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets. The Internal Revenue Service may challenge all or part of the tax basis increase, other tax benefits, and associated increased deductions, and a court could sustain such a challenge.

In connection with the closing of the Transactions (the “Closing”), NuScale entered into 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 must 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. NuScale’s obligations under the Tax Receivable Agreement accelerate upon a change in control and certain other termination events, as defined therein.

NuScale will benefit from the remaining 15% of cash tax savings, if any, that NuScale realizes as a result of such tax benefits. For purposes of the Tax Receivable Agreement, the cash tax savings will be computed by comparing NuScale’s actual income tax liability to the amount of such taxes that NuScale would have been required to pay had there been no increase to the tax basis of its assets as a result of the Transaction or the exchanges and had NuScale not entered into the Tax Receivable Agreement (calculated by making certain assumptions).

The term of the Tax Receivable Agreement will continue until all such tax benefits have been utilized or expired, unless NuScale exercises its right to terminate the Tax Receivable Agreement for an amount based on the present value of the agreed payments remaining to be made under the agreement (as described in more detail below), there is a change of control (as described in more detail below) or NuScale breaches any of its material obligations under the Tax Receivable Agreement, in which case all obligations will generally be accelerated and due as if NuScale had exercised its right to terminate the Tax Receivable Agreement. Estimating the amount of payments that may be made under the Tax Receivable Agreement is by its nature imprecise, as the calculation depends on a variety of factors. The actual increase in tax basis of the assets of NuScale LLC, as well as the amount and timing of any payments under the Tax Receivable Agreement, will vary depending upon several factors, including:

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 14

(1)the timing of exchanges of NuScale LLC Class B Units for shares of Class A Common Stock under the A&R NuScale LLC Agreement — for instance, the increase in any tax deductions will vary depending on the fair value, which may fluctuate over time, of the relevant NuScale LLC Class B Units at the time of each exchange;

(2)the price of Class A Common Stock at the time of the exchange — the increase in any tax deductions, as well as the tax basis increase in other assets or other tax benefits, is proportional to the price of Class A Common Stock at the time of the exchange;

(3)the extent to which such exchanges are taxable — if an exchange is not taxable for any reason, an increase in the tax basis of the assets of NuScale LLC (and thus increased deductions) may not be available as a result of such exchange; and

(4)the amount and timing of our income — we will be required to pay 85% of the cash tax savings, if any, as and when realized.

If NuScale does not have taxable income (determined without regard to the tax basis and other tax benefits that are subject to the Tax Receivable Agreement), NuScale will generally not be required (absent a change of control or other circumstances requiring an early termination payment) to make payments under the Tax Receivable Agreement for that taxable year because no cash tax savings will have been actually realized. However, any cash tax savings that do not result in realized benefits in a given tax year may generate tax attributes that may be utilized to generate benefits in future tax years. The utilization of such tax attributes will result in payments under the Tax Receivable Agreement.

We expect that future payments under the Tax Receivable Agreement in respect of subsequent exchanges of NuScale LLC Class B Units for shares of Class A Common Stock under the A&R NuScale LLC Agreement will be substantial. It is possible that future transactions or events could increase or decrease the actual cash tax savings realized and the corresponding payments under the Tax Receivable Agreement. There may be a material negative effect on NuScale’s liquidity if, as a result of timing discrepancies or otherwise, the payments under the Tax Receivable Agreement exceed the actual cash tax savings we realize in respect of the tax attributes subject to the Tax Receivable Agreement and/or distributions to NuScale by NuScale LLC are not sufficient to permit NuScale to make payments under the Tax Receivable Agreement after NuScale has paid its taxes. The payments under the Tax Receivable Agreement are not conditioned upon the TRA Holders’ continued ownership of NuScale or NuScale LLC. As of December 31, 2023, there have been 23,919,679 Class B units exchanged for shares of Class A common stock. Associated with these exchanged units we have calculated an implied TRA obligation of $60,347,000 as of December 31, 2023. However, given NuScale Corp's current tax situation we conclude the liability is not probable, and thus no liability related to projected obligations under the TRA has been recorded.

In addition, the Tax Receivable Agreement provides that upon a change of control, NuScale’s obligations under the Tax Receivable Agreement will accelerate as if NuScale had exercised its early termination right based on certain assumptions (as described below), including that NuScale would have sufficient taxable income to fully utilize the deductions arising from the increased tax deductions and tax basis and other benefits related to the Tax Receivable Agreement.

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 15

Furthermore, NuScale may elect to terminate the Tax Receivable Agreement early by making an immediate payment equal to the present value of the anticipated future cash tax savings. In determining such anticipated future cash tax savings, the Tax Receivable Agreement includes several assumptions, including (1) that any NuScale LLC Class B Units that have not been exchanged are deemed exchanged for the market value of Class A Common Stock and the amount of cash that would have been transferred if the exchange had occurred at the time of termination, (2) NuScale will have sufficient taxable income in each future taxable year to fully utilize all relevant tax attributes subject to the Tax Receivable Agreement, (3) the tax rates for future years will be those specified in the law as in effect at the time of termination, and (4) certain non-amortizable, non-deductible assets are deemed disposed of within specified time periods. In addition, the present value of such anticipated future cash tax savings are discounted at a rate equal to the lesser of (i) 6.5% and (ii) LIBOR plus 400 basis points.

As a result of either an early termination or a change of control, NuScale could be required to make payments under the Tax Receivable Agreement that exceed our actual cash tax savings. Consequently, our obligations under the Tax Receivable Agreement could have a substantial negative impact on our liquidity and could have the effect of delaying, deferring or preventing certain mergers, asset sales, other forms of business combinations or other changes of control. There can be no assurance that we will be able to finance our obligations under the Tax Receivable Agreement.

Finally, because NuScale is a holding company with no operations of its own, its ability to make payments under the Tax Receivable Agreement depends on the ability of NuScale LLC to make distributions to it. To the extent that NuScale is unable to make payments under the Tax Receivable Agreement for any reason, such payments will be deferred and will accrue interest until paid, which could negatively impact NuScale’s results of operations and could also affect its liquidity in periods in which such payments are made.

Indemnification Agreements with Officers and Directors and Directors’ and Officers’ Liability Insurance

NuScale has entered into indemnification agreements with each of its executive officers and directors. The indemnification agreements and our certificate of incorporation and Bylaws require that NuScale indemnify its directors to the fullest extent not prohibited by Delaware law. Subject to certain limitations, NuScale’s Bylaws also require us to advance expenses incurred by our directors and officers. NuScale also maintains a general liability insurance policy, which covers certain liabilities of its directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers.

Registration Rights Agreement

Simultaneously with the Closing, NuScale and certain NuScale and NuScale LLC securityholders, including Fluor Enterprises, Inc. and Samsung C&T Corporation (the “RRA Related Persons”) entered into a Registration Rights Agreement covering approximately 193.3 million shares of Class A Common Stock (the “Registration Rights Agreement”), pursuant to which the securityholders have demand, shelf and piggyback registration rights. We registered all of the registrable securities on a registration statement on Form S-1, effective June 30, 2022, as amended by Post-Effective Amendment No. 1, to Form S-1, effective March 23, 2023, and Post-Effective Amendment No. 2 to Form S-1 on Form S-3, effective

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 16

June 2, 2023. Underwriting discounts and selling commissions for sales pursuant to the registration statement will be borne by the securityholders. The Registration Rights Agreement contains customary cross-indemnification provisions under which NuScale must indemnify holders of registrable securities for material misstatements or omissions in the registration statement attributable to NuScale, and holders of registrable securities must indemnify NuScale for material misstatements or omissions attributable to them. The securities will cease to be registrable securities when the securities shall have been disposed of in accordance with the registration statement; when the securities shall have been otherwise transferred and are no longer subject to resale restrictions; when the securities cease to be outstanding; or following the third anniversary of the Closing, when the securities may be sold without registration pursuant to Rule 144 under the Securities Act without the requirement to comply with any limitations. Depending on the Company’s share price and the number of registered shares sold by an RRA Related Person, each RRA Related Person could receive more than $120,000 from such sales, but it is not possible to estimate such amounts.

Policies and Procedures for Related Person Transactions

NuScale has adopted a written related person transaction policy that sets forth the policies and procedures for the review and approval or ratification of related person transactions.

A “Related Person Transaction” is defined (consistent with SEC and NYSE listing standards) as a transaction, arrangement or relationship in which NuScale or any of its subsidiaries was, is or will be a participant, the amount of which involved exceeds $120,000, and in which any related person had, has or will have a direct or indirect material interest. Transactions involving compensation for services provided to NuScale or any of its subsidiaries as an employee or director will be pre-approved under this policy if such arrangements meet certain requirements specified in the policy. A “related person” means:

•any person who is, or at any time during the applicable period was, one of NuScale’s executive officers or one of NuScale’s directors or a nominee for director;

•any person who is the beneficial owner of more than five percent of any class or series of its voting stock; and

•any immediate family member of any of the foregoing persons, which means any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law of a director, executive officer or a beneficial owner of more than five percent of its voting stock, and any person (other than a tenant or employee) sharing the household of such director, executive officer or beneficial owner of more than five percent of its voting stock.

NuScale has policies and procedures designed to minimize potential conflicts of interest arising from any dealings it may have with its affiliates and to provide appropriate procedures for the disclosure of any real or potential conflicts of interest that may exist from time to time. Specifically, pursuant to its charter, the Audit Committee has the responsibility to review related person transactions.

Under the related person transaction policy, the related person in question (or if the related person is an immediate family member of a director or executive officer, the director or executive officer) will be

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 17

required to present information regarding the proposed related person transaction to NuScale’s Chief Compliance Officer. The Chief Compliance Officer, in consultation with the General Counsel, will evaluate the information and if the Chief Compliance Officer determines that the proposed transaction would constitute a related person transaction, the Chief Compliance Officer will report the Related Person Transaction and provide a summary of all material facts to the Audit Committee for review. To identify related person transactions in advance, NuScale expects to rely on information supplied by its executive officers, directors and certain significant stockholders. In considering related person transactions, the Audit Committee is expected to consider the relevant available facts and circumstances, which may include:

•the related person’s interest in the transaction;

•the approximate dollar value of the amount involved in the transaction, particularly as it relates to the related person;

•whether the transaction was initiated by NuScale or the related person;

•whether the transaction was undertaken in the ordinary course of business of NuScale;

•whether the transaction with the related person is proposed to be, or was, entered into on terms no less favorable to NuScale than terms that could have been reached with an unrelated third party;

•the purpose of, and the potential benefits to NuScale of, the transaction; and

•any other information regarding the transaction or the related person that would be material to investors in light of the circumstances of the particular transaction.

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 18

DIRECTOR AND EXECUTIVE COMPENSATION

Our compensation policies and philosophies are designed to:

•attract, retain and motivate senior management leaders who are capable of advancing NuScale’s mission and strategy and, ultimately, creating and maintaining its long-term equity value. Such leaders must engage in a collaborative approach and possess the ability to execute its business strategy in an industry characterized by competitiveness and growth;

•reward senior management in a manner aligned with NuScale’s financial and other performance measures;

•align senior management’s interests with equity owners’ long-term interests through equity participation and ownership; and

•not incentivize imprudent risk-taking.

Decisions with respect to the compensation of NuScale’s executive officers, including its named executive officers, are made by the Compensation Committee of our Board. The terms of each named executive officer’s employment agreement are described below under “Executive Employment Agreements.” The Compensation Committee relied on the same compensation consultant it used when determining director compensation, FW Cook, when reviewing the base pay and incentive plan for the Company’s executives. The consultant recommended that the Company adopt a compensation program targeted at the median of industry peers, for both cash compensation (salary plus target bonus) and equity, which the Board adopted.

In addition to base salary and annual bonuses, we use stock-based awards to promote our interests by providing executives with the opportunity to acquire equity interests as an incentive for continuing employment with us and to align their interests with those of our equity holders.

We have a Stock Ownership and Anti-Hedging/Pledging Policy that requires non-employee directors and executive officers to acquire and hold sufficient shares of our common stock to meaningfully participate in the risks and rewards of ownership with NuScale stockholders, and that prohibit hedging, pledging and similar transactions that would minimize the risks of stock ownership. Non-employee directors and executive officers are required to acquire and retain the net after-tax shares received as compensation until accumulated holdings have a market value equal to a multiple of their base compensation, as indicated below.

•Non-employee directors    5x annual cash retainer

•CEO    5x base salary

•CFO and CEO Direct Reports     2x base salary

Compensation paid to management based on performance, including any award under NuScale’s 2022 Long-Term Incentive Plan (the “Long-Term Incentive Plan”), is subject to a recoupment (“clawback”) policy. In the event of a restatement of incorrect financial results, this policy will enable the Board or the Compensation Committee, if it determines appropriate and subject to applicable laws, to seek

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 19

reimbursement from award recipients of any portion of an award that would not have been earned based on corrected financial results.

Director Compensation

Our non-employee directors, which are those individuals that are not employed by us or by Fluor, receive compensation for their services as directors and members of committees of the Board. Compensation for Board service includes an annual $80,000 cash retainer (or stock equivalent), payable quarterly in arrears; an additional annual cash retainer, payable quarterly in arrears, of $50,000 for the non-Executive Chair of the Board; and a $30,000 cash retainer for the Lead Independent Director if one is appointed separate from the non-Executive Chair of the Board. We do not require a Lead Independent Director at this time.

We also pay additional annual cash retainers, quarterly in arrears, for committee members as follows:

Committee	Member	Additional to Chair
Audit	$  10,000	$  12,500
Compensation	$    7,500	$    8,000
Nominating and Governance	$    5,000	$    6,500

In addition, the non-employee directors were each granted time-based Restricted Stock Unit (“RSU”) awards with a grant value equal to $110,000 annually, that vest quarterly over one year, and one-time RSU awards when they joined the Board with a grant value equal to $110,000, that vest quarterly over three years.

The Board relied on FW Cook, a compensation consultant selected through a competitive process, to help it develop the compensation plan described above. FW Cook was retained by the Company at the direction of the Organization & Compensation Committee. The Organization & Compensation Committee directs when the compensation consultant is engaged., Since the initial engagement the compensation consultant has been providing recommendations regarding executive compensation, the Company’s long-term incentive plan and Board compensation. In November 2021, FW Cook performed an analysis of 17 comparable peer companies when recommending the total cash and equity compensation adopted by the Board, which targeted total director compensation at about the 50th percentile.

In February 2023, FW Cook provided an updated review of total compensation for directors, referencing 18 comparable peer companies. FW Cook recommended that, to remain at the 50th percentile, and to remain competitive in retaining and attracting new Board members, the Company should increase its total director compensation by $30,000 annually. Effective May 2023, the Board adopted a resolution increasing only the annual equity-based compensation such that the non-employee directors will be annually granted time-based RSU awards with a grant value equal to $110,000, that vest quarterly over one year. The amount of cash compensation remains unchanged.

Executive Compensation

This section provides an overview of NuScale’s compensation programs, including a description of the material factors necessary to understand the information disclosed in the summary compensation table below, and an overview of compensation arrangements that were effective in 2023. This discussion may contain forward-looking statements that are based on NuScale’s current plans, considerations, expectations and determinations regarding future compensation programs.

For the year ended December 31, 2023, our named executive officers (“NEOs”) were:

•John L. Hopkins    Chief Executive Officer (CEO) and President

•R. Ramsey Hamady    Chief Financial Officer

•Thomas Mundy*    President, VOYGR Services

*    Thomas Mundy’s employment with NuScale ended on January 5, 2024.

We believe that our success is driven by our employees, and that our employees will only be successful if they have leaders who provide strategic vision and direction. To attract talented leaders, we offer a balanced compensation package that includes competitive base pay and incentive compensation that rewards both short and long-term value creation.

Our compensation program includes the following pay delivery components:

•Base pay salary structure that is competitive in the labor markets and industries in which we operate;

•An incentive (cash bonus) program that rewards key employees based on annual results;

•An equity program that attracts, retains, and motivates longer-term excellence;

•A performance management system that links performance to desired outcomes; and

•A job evaluation system that focuses on external cost of labor, with a secondary review of internal equity.

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 21

Base Pay

For executives, including our NEOs, we target base pay in the 50th percent of base of pay according to industry benchmarking studies with 50th percent being the midpoint of base compensation in the industry.

NuScale Professional Incentive Plan

We adopted the NuScale Professional Incentive Plan on January 1, 2015, to focus senior staff, managers and other personnel designated by our chief executive officer on critical success factors. Under the plan, eligible employees may earn an annual cash bonus equal to a percentage of their base pay if they achieve annual performance goals, which may include company performance measures and individual goals. We set target and maximum incentive payment amounts by job classification. Typically, plan participants are identified in the third quarter; company performance measures are proposed by our CEO and approved by our Compensation Committee, and individual performance measures are proposed by designated managers and approved by our CEO; and goals are fixed in the first quarter.

The Board approves goals for the NuScale Professional Incentive Plan annually and a short-term incentive bonus is paid based on the level of management’s achievement of those goals. The Board applies weight to each goal in proportion to its assessment of the importance of each goal to overall Company success. In 2022, the Board adopted seven new NuScale Professional Incentive Plan goals for management related to: Funding, Customer Acquisition, Securing New Contracts, Achievement of Development Milestones, Revenue, Spending, and Corporate Excellence. In February 2023, the Board assessed management’s performance against these 2022 incentive goals and determined that performance justified a payout at 126.4 percent of target, which was paid to bonus-eligible employees, including the NEOs, in March 2023. In 2023, the Board adopted ten NuScale Professional Incentive Plan goals for management related to: Funding, Customer Acquisition, Securing New Contracts, Achievement of Development and Delivery Milestones, Revenue, Spending, Investor Relations, Environmental Targets, and Social Attributes. In February 2024, the Board assessed management’s performance against these 2023 incentive goals and determined that performance justified a payout at 94.6 percent of target, which the Company paid to bonus-eligible employees, including the NEOs, in March 2024.

Long-Term Incentive Plan

Our executives, including our NEOs, are eligible for awards under the Long-Term Incentive Plan, and non-executives may also be eligible if approved by the Compensation Committee.

We expect the primary component of our NEOs’ total compensation will be equity-based compensation to tie total compensation to long-term stockholder value.

Historically as a public company, NuScale has granted 100% time-vested RSUs as our equity-based compensation vehicle. The Company’s long-term incentive plan also permits issuing option awards as part of our equity-based compensation. We believe RSUs align the long-term interests of management and stockholders and help efficiently manage overall stockholder dilution from stock awards. RSU grant amounts and vesting, whether for new hire or subsequent grants, are established by the Compensation Committee after receiving recommendations from the Senior Human Resources Officer and the CEO. The

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 22

only employee RSUs currently granted vest over three years, and absent a change in control, vesting will not accelerate as a result of termination of employment. We anticipate that grants in future years may include performance shares and stock options in addition to RSUs.

For periodic grants, the Senior Human Resource Officer, the CEO and the Compensation Committee will consider a variety of factors, including the executive’s level of responsibility, past contributions to performance and expected contributions, and relative compensation of similarly situated leaders both within the company and in companies with whom we compete directly for talent.

Employee Benefits

We provide all of our employees, including our NEOs, broad-based employee benefits that are intended to attract and retain employees while providing them with health and welfare benefits, including medical, dental, vision, life and disability insurance coverage, and the ability for eligible participants to participate in our 401(k) plan.

Executive Employment Agreement, Executive Severance Policy and Executive Change in Control Plan

The employment agreement for Mr. Hopkins provides that if employment is terminated by us without “cause,” other than in connection with a change of control, the executive will be entitled to severance consisting of (i) a lump sum equal to three years’ base salary plus target bonus; (ii) a pro-rated portion of any annual bonus; (iii) continued medical, dental and vision coverage for up to 18 months; (iv) any equity-based compensation awards, other than performance-based equity awards, that are outstanding will continue to vest as if the executive was still employed; (v) any performance-based equity awards will, to the extent the performance criteria are met, be earned at 100% of target, pro-rated based on the number of months executive worked during the performance period; and (vi) all outstanding retention awards will fully vest. If employment is terminated by us without “cause” or by the executive for “good reason,” each in connection with a change in control, the executive will be entitled to receive severance consisting of (a) a lump-sum equal to three years’ base salary plus target bonus; (b) if the successor fails to assume the annual incentive plan, a pro-rated portion of any annual bonus; (c) continued medical, dental and vision coverage for up to 18 months; (d) reimbursement of outplacement services expenses incurred in the 12 months following termination up to $25,000; (e) the full vesting of any retention awards; and (f) the full vesting of all equity awards other than performance-based awards and, with respect to performance-based awards, vesting at 100% of target. Mr. Hopkins is the only NuScale executive with an individual employment contract.

In the employment agreement, (1) “cause” is defined as commission of any felony or any crime involving moral turpitude or dishonesty; participation in a fraud against NuScale or any of its affiliates; willful and material breach of the executive’s duties that has not been cured within 30 days after written notice from

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 24

NuScale of such breach; intentional and material damage to NuScale’s or any of its affiliates’ property; material violation of any policy of NuScale or any of its affiliates or material breach by the executive of his Employee Proprietary Information and Inventions Assignment Agreement with NuScale; and (2) “good reason” is defined as a material diminution of executive’s aggregate compensation, including, without limitation, base salary, annual bonus opportunity, and equity incentive compensation opportunities (other than a base salary, annual bonus opportunity, or equity compensation opportunity reduction of not more than 20% applicable to all similarly situated employees); a material diminution of executive’s authority, duties or responsibilities; or any other action or inaction that constitutes a material breach by NuScale of the agreement under which the executive provides services (e.g., failure of successor to assume the employment agreement or breach of same).

NuScale’s obligation to make the severance payments, and the executive’s right to retain the payments, is wholly conditioned on the executive providing a general release of claims in favor of NuScale and continuing to comply with his obligations under the employment agreement, including the restrictive covenants. The employment agreements each contain (i) a perpetual confidentiality covenant; (ii) non- competition and non-solicitation of business partners covenants during employment and for one year thereafter; (iii) a non-solicitation covenant with respect to employees and other service providers during employment and for twelve months thereafter; and (iv) a non-disparagement obligation.

The employment agreement also provides that, regardless of whether the executive’s employment is terminated, if there is a change in control and (i) if the successor does not assume NuScale’s annual incentive plan, the annual bonus will be paid in the amount of the target bonus; (ii) if the successor does not assume any outstanding retention awards, then such awards will become immediately fully vested; (iii) if the successor does not assume the equity compensation plan in which the executive participates or grant comparable awards in substitution of the outstanding awards under any such plan, then any outstanding equity-based compensation awards granted to the executive under such plan, other than performance-based equity awards, will become immediately fully vested, and any performance-based equity awards will immediately vest assuming target performance.

NuScale and each of its executive officers, including its NEOs other than Mr. Hopkins, are parties to an Agreement to Terminate Employment Agreement, which took effect at the closing of the Transaction and includes an agreement by each executive to be bound by NuScale’s executive severance policy and executive change in control plan.

NuScale’s executive severance policy for its executives who do not have employment agreements provides that if employment is terminated by us without “cause,” the executive will be entitled to severance consisting of a lump sum equal to one year’s base salary plus target bonus; (ii) continued medical, dental and vision coverage for up to one year; and (iii) the vesting of all equity awards other than performance-based awards as and if provided in the award agreements and, with respect to performance-based awards, and other awards subject to further vesting, such unvested awards will be terminated. “Cause” in the policy has the same meaning as in the employment agreements described above. NuScale’s obligation to make the severance payments is wholly conditioned on the executive providing a general release of claims in favor of NuScale.

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 25

NuScale’s change in control plan for each of its executives who do not have employment agreements provides that if the executive’s employment is terminated within two years following a change of control by us without “cause,” or by the executive for “good reason” the executive will be entitled to severance consisting of (i) a lump sum equal to one or one and a half times the executive’s base salary plus target bonus; (ii) a prorated annual bonus; (iii) continued medical, dental and vision coverage for up to one year; (iv) reimbursement of outplacement services expenses incurred in the 12 months following termination up to $25,000; and (v) the full vesting of all equity awards other than performance-based awards and, with respect to performance-based awards, vesting based on 100% of target. “Cause” and “good reason” in these agreements have the same meanings as in the employment agreements described above. A change of control includes a person or group holding more than 25% of either (1) the then-outstanding shares of common stock of NuScale or (2) the combined voting power of the then outstanding voting securities of NuScale entitled to vote generally in the election of our Board.

Our obligation to make the severance payments, and the executive’s right to retain the payments, is conditioned on the executive providing a general release of claims in favor of NuScale and continuing to comply with his or her obligations under the Company’s severance policy, including the restrictive covenants. The employment agreements each contain (i) a perpetual confidentiality covenant; (ii) non- competition and non-solicitation of business partners covenants during employment; (iii) a non- solicitation covenant with respect to employees and other service providers during employment and for twelve months thereafter; and (iv) a non-disparagement obligation.

The change in control plan also provides that, regardless of whether the executive’s employment is terminated, if there is a change in control and (i) if the successor does not assume NuScale annual incentive plan, the annual bonus will be paid in the amount of the target bonus; (ii) if the successor does not assume any outstanding retention awards, then such awards will become immediately fully vested; (iii) if the successor does not assume the equity compensation plan in which the executive participates or grant comparable awards in substitution of the outstanding awards under any such plan, then any outstanding equity-based compensation awards granted to executive under such plan, other than performance-based equity awards, will become immediately fully vested, and any performance-based equity awards will immediately vest assuming target performance.

Mr. Hopkins’ employment agreement and the change in control plan and severance policy provide that, if payments to the executive pursuant to the agreement (when considered with all other payments made to the executive as a result of a change in control that are subject to section 280G of the Code)) (the amount of all such payments, collectively, the “Parachute Payment”) results in the executive becoming liable for the payment of any excise taxes pursuant to section 4999 of the Code, together with any interest or penalties with respect to such excise tax (“280G Excise Tax”), then NuScale will automatically reduce (the “Reduction”) the executive’s Parachute Payment to the minimum extent necessary to prevent the Parachute Payment (after the Reduction) from being subject to the Excise Tax, but only if, by reason of the Reduction, the after-tax benefit of the reduced Parachute Payment exceeds the after-tax benefit if such Reduction were not made. If the after-tax benefit of the reduced Parachute Payment does not exceed the after-tax benefit if the Parachute Payment is not reduced, then the Reduction will not apply. If the Reduction is applicable, the Parachute Payment will be reduced in such a manner that provides the

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 26

executive with the best economic benefit and, to the extent any portions of the Parachute Payment are economically equivalent with each other, each will be reduced pro rata.

Emerging Growth Company (EGC) Status

As an EGC, NuScale is exempt from certain requirements related to executive compensation, including the requirements to hold a nonbinding advisory vote on executive compensation and to provide information relating to the ratio of total compensation of NuScale’s chief executive officer to the median of the annual total compensation of all of NuScale’s employees and pay versus performance. In addition, NuScale must disclose compensation for only three current NEOs rather than five.

PROPOSAL 1:

ELECTION OF DIRECTORS

Our Bylaws provide that our Board must consist of not fewer than five nor more than eleven directors. Our Board currently consists of ten members, seven of whom have served since May 2022, when we completed the Transactions, with two members being appointed in December 2022 and one member being appointed in December 2023. Mr. Sorrells' service will end at the Annual Meeting on May 24, 2024, at which time the Board size will be set to nine directors. Each director will be elected to serve until the next annual meeting or until a successor is duly elected and qualified or until his or her earlier death, resignation or removal.

The table below sets forth information with respect to our directors that our Board has nominated to serve as directors:

Name	Age
Alan L. Boeckmann	75
James R. Breuer	55
Bum-Jin Chung	59
Alvin C. Collins, III	51
Shinji Fujino	61
James T. Hackett	70
John Hopkins	70
Kent Kresa	86
Kimberly O. Warnica	50

Upon the recommendation of our Nominating and Governance Committee, our Board has nominated the above individuals as directors. If elected at the Annual Meeting, each of these nominees will serve until the next annual meeting or until his or her successor has been duly elected, unless earlier due to death, resignation or removal. Each person nominated for election has agreed to serve if elected, and we have no reason to believe that any nominee will be unable to serve. If any nominee is not able to serve, proxies will be voted in favor of the other nominees and may be voted for a substitute nominee, unless our Board chooses to reduce the number of directors serving on our Board.

The Board recommends supporting the election of the above-named directors. Unless otherwise instructed, the proxy holders will vote the proxies received by them "FOR" the election of the above individuals as directors.

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 28

PROPOSAL 2:

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM

The Audit Committee of our Board of Directors has engaged Ernst & Young LLP (E&Y) as our independent registered public accounting firm for the fiscal year ending December 31, 2024. We are asking our stockholders to ratify the selection of E&Y as our independent registered public accounting firm. Although ratification is not required by our Bylaws or otherwise, we are submitting the selection of E&Y to our stockholders for ratification as a matter of good corporate practice and because we value our stockholders' views on our independent registered public accounting firm. If our stockholders do not ratify the selection, the Audit Committee will review its future selection of independent auditors. Even if our stockholders ratify the selection, our Audit Committee, in its discretion, may appoint another independent registered public accounting firm at any time during the year if the Audit Committee believes that such a change would be in the best interest of NuScale and our stockholders. Representatives of E&Y are expected to be present at the Annual Meeting, and they will have the opportunity to make a statement if they so desire and to respond to appropriate questions.

The Board recommends a vote “FOR” the ratification of the appointment of E&Y as our independent registered public accounting firm for the fiscal year ending December 31, 2024.

AUDIT COMMITTEE REPORT

We hereby report that the Audit Committee has:

1.    Reviewed and discussed with management and E&Y, together and separately, NuScale’s audited consolidated financial statements contained in NuScale’s Annual Report on Form 10-K for the 2023 fiscal year.

In addition, we discussed and reviewed the identification of the critical audit matter with management and with E&Y throughout the year.

Based on our review and discussions with NuScale’s management and independent registered public accountants, we recommended to our Board of Directors that the audited financial statements be included in NuScale’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 for filing with the SEC.

DELINQUENT SECTION 16(A) REPORTS

Section 16(a) of the Exchange Act requires our directors, executive officers and holders of more than 10% of Class A Common Stock to file with the SEC reports regarding their ownership and changes in ownership of our securities. In addition to requiring prompt disclosure of open-market purchases or sales of Company shares, Section 16(a) applies to technical situations. NuScale maintains and regularly reviews procedures to assist NuScale in identifying reportable transactions and assists our directors and executive officers in preparing reports regarding their ownership and changes in ownership of our securities and filing those reports with the SEC on their behalf. Based solely upon a review of filings with the SEC, a review of Company records and written representations by our directors and executive officers, NuScale believes that all Section 16(a) filing requirements were complied with for 2023, with the following exceptions: Bum-Jin Chung, Shinji Fujino, and Thomas Mundy each filed one late Form 4.

IMPORTANT INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

Why am I receiving these materials?

The Board is making these proxy materials available to you on the Internet or, upon your request, by delivering printed versions of these materials to you by mail, in connection with the solicitation of proxies for use at our 2024 Annual Meeting of Stockholders (the "Annual Meeting"), or at any adjournment or postponement of the Annual Meeting. The Annual Meeting will occur on May 24, 2024, at 2:00 p.m. Pacific Time at www.virtualshareholdermeeting.com/SMR2024.

What is “householding” and how does it affect me?

NuScale has adopted the “householding” procedure approved by the SEC, which allows us to deliver one set of documents to a household of stockholders instead of delivering a set to each stockholder in a household, unless we have been instructed otherwise. This procedure is more environmentally friendly and cost-effective because it reduces the number of copies to be printed and mailed. Stockholders who receive proxy materials in paper form will continue to receive separate proxy cards to vote their shares. If you would like to change your householding election, request that a single copy of the proxy materials be sent to your address, or request a separate copy of the proxy materials, please contact Broadridge Financial Solutions, Inc., by calling (800) 322-2885 or by writing to Broadridge Householding Department, 51 Mercedes Way, Edgewood, New York 11717. We will promptly deliver the proxy materials to you upon receipt of your request. If you hold your shares in street name, please contact your bank, broker, or other record holder to request information about householding.

What is included in these materials?

These materials include this Proxy Statement for the Annual Meeting and our Annual Report to Stockholders, which includes our Annual Report on Form 10-K for the year ended December 31, 2023. We are first making these materials available to you on the Internet on or about April 12, 2024.

Who is entitled to vote at the Annual Meeting?

Holders of our common stock as of the close of business on March 27, 2024, the record date, may vote at the Annual Meeting. As of the record date, there were 86,760,243 shares of Class A Common Stock and 154,473,395 shares of Class B Common Stock outstanding. Each share of Class A Common Stock and each share of Class B Common Stock is entitled to one vote. Holders of Class A Common Stock and Class B Common Stock will vote as a single class on all matters described in this proxy statement.

What is the difference between holding shares as a stockholder of record and as a beneficial owner?

If your shares are registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, you are considered the stockholder of record with respect to those shares, and the Notice of Internet Availability of Proxy Materials was sent directly to you by us. As a stockholder of record, you may vote your shares at the Annual Meeting or by proxy as described below.

If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the "beneficial owner" of shares held in street name. The Notice and, upon your request, the proxy materials were forwarded to you by your broker, bank or other nominee who is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to direct your bank, broker or other nominee on how to vote your shares by following their instructions for voting.

How can I vote my shares?

If you are a stockholder of record, you may vote:

•Via the Internet. You may vote by proxy via the Internet by following the instructions found on the proxy card.

•By Telephone. You may vote by proxy by calling the toll-free number found on the proxy card.

•By Mail. You may vote by proxy by filling out the proxy card and returning it in the envelope provided.

•Internet and telephone voting will be available 24 hours a day and will close at 11:59 p.m. Eastern Time on Thursday, May 23, 2024.

If you are a beneficial owner of shares held in street name, you should have received from your bank, broker or other nominee instructions on how to vote or instruct the broker to vote your shares, which are

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 36

generally contained in a "voting instruction form" sent by the broker, bank or other nominee. Please follow their instructions carefully. Beneficial owners generally may vote:

•Via the Internet. You may vote by proxy via the Internet by following the instructions on the voting instruction form provided to you by your broker, bank or other nominee.

•By Telephone. You may vote by proxy by calling the toll-free number found on the voting instruction form provided to you by your broker, bank or other nominee.

•By Mail. You may vote by proxy by filling out the voting instruction form and returning it in the envelope provided to you by your broker, bank or other nominee.

If you received more than one Notice of Internet Availability of Proxy Materials or proxy card, then you hold shares of NuScale common stock in more than one account. You should vote via the Internet, by telephone, by mail or at the Annual Meeting for all shares held in each of your accounts.

If I submit a proxy, how will it be voted?

When proxies are properly signed, dated and returned, the shares represented by the proxies will be voted in accordance with the instructions of the stockholder. If no specific instructions are given, you give authority to your proxy holder to vote the shares in accordance with the recommendations of our Board as described above. If any director nominee is not able to serve, proxies will be voted in favor of the other nominee and may be voted for a substitute nominee, unless our Board chooses to reduce the number of directors serving on our Board. If any matters not described in this Proxy Statement are properly presented at the Annual Meeting, then the proxy holders will use their own judgment to determine how to vote the shares. If the Annual Meeting is adjourned, the proxy holders can vote your shares on the new meeting date as well, unless you have revoked your proxy.

Can I change my vote or revoke my proxy?

Yes. If you are a stockholder of record, you can change your vote or revoke your proxy before it is exercised by:

•Written notice to our Corporate Secretary; or

•Timely delivery of a valid, later-dated proxy or a later-dated vote by telephone or on the Internet.

If you are a beneficial owner of shares held in street name, you should follow the instructions of your bank, broker or other nominee to change or revoke your voting instructions. You may also vote at the Annual Meeting if you obtain a legal proxy as described above.

Can I attend the Annual Meeting in-person?

No, the Annual Meeting will be held virtually on the Internet. There will not be an in-person meeting.

What constitutes a quorum at the Annual Meeting?

The presence, at the virtual meeting or by proxy, of the holders of a majority in voting power of the shares of our common stock issued and outstanding and entitled to vote at the Annual Meeting must be present

    NUSCALE POWER CORPORATION | 2024 PROXY STATEMENT – Page 37

or represented to conduct business at the Annual Meeting. You will be considered part of the quorum if you return a signed and dated proxy card, or if you vote by telephone or Internet.

Abstentions and withhold votes are counted as "shares present" at the Annual Meeting for purposes of determining whether a quorum exists. Proxies submitted by banks, brokers or other holders of record holding shares for you as a beneficial owner that do not indicate a vote for some of or all the proposals because that holder does not have voting authority and has not received voting instructions from you (so-called "broker non-votes") are also considered "shares present" for purposes of determining whether a quorum exists. If you are a beneficial owner, these holders are permitted to vote your shares on the ratification of the appointment of our independent registered public accounting firm, even if they do not receive voting instructions from you.

What is the impact of abstentions, withhold votes and broker non-votes?

Abstentions, withhold votes and broker non-votes are considered "shares present" for the purpose of determining whether a quorum exists, but will not affect the outcome of the vote on the election of directors or on the ratification of the appointment of our independent registered public accounting firm. Under NYSE Rule 452, without voting instructions from beneficial owners, brokers will have discretion to vote on the ratification of the appointment of the independent registered public accounting firm but not on the election of directors. Therefore, for your voice to be heard, it is important that you vote.

What is the voting requirement to approve each of the proposals?

Provided that there is a quorum, the voting requirements are as follows:

Proposals	Vote Required	Broker Discretionary Voting Allowed?
Election of Directors	Plurality of votes cast	No
Ratification of Appointment of Independent Registered Public Accounting Firm	Majority of votes cast	Yes

Who pays for the cost of this proxy solicitation?

We will pay all the costs of preparing, mailing and soliciting the proxies. We will ask brokers, banks, voting trustees and other nominees and fiduciaries to forward the proxy materials to the beneficial owners of our common stock and to obtain the authority to execute proxies. We will reimburse them for their reasonable expenses upon request. In addition to mailing proxy materials, our directors, officers and employees may solicit proxies in person, by telephone or otherwise. These individuals will not be specially compensated.

Where can I find the voting results of the Annual Meeting?

We will announce preliminary voting results at the Annual Meeting. We also will disclose voting results on a Current Report on Form 8-K that we will file with the SEC within four business days after the Annual Meeting.

Why did I receive a Notice of Internet Availability of Proxy Materials rather than a full set of proxy materials?

In accordance with the SEC rules, we have elected to furnish our proxy materials, including this Proxy Statement and the Annual Report, primarily via the Internet rather than by mailing the materials to stockholders. The Notice of Internet Availability of Proxy Materials provides instructions on how to access our proxy materials on the Internet, how to vote, and how to request printed copies of the proxy materials. Stockholders may request to receive future proxy materials in printed form by following the instructions contained in the Notice of Internet Availability of Proxy Materials. We encourage stockholders to take advantage of the proxy materials on the Internet to reduce the costs and environmental impact of our Annual Meeting.

How can I obtain NuScale's Form 10-K and other financial information?

Stockholders can access our 2023 Annual Report, which includes our Form 10-K, and other financial information, on our website at www.nuscalepower.com under the caption "Investors." Alternatively, stockholders can request a paper copy of the Annual Report by writing to: NuScale Power Corporation, 1100 NE Circle Blvd., Suite 200, Corvallis, OR 97330, Attention: Corporate Secretary.
