NuScale Power (NYSE: SMR) details 2026 meeting, board slate and TRA exposure

Q: What is NuScale Power (SMR) asking stockholders to approve at the 2026 annual meeting?

Stockholders are being asked to elect nine directors, approve a non-binding advisory “Say on Pay” vote on executive compensation, and ratify Ernst & Young LLP as NuScale’s independent registered public accounting firm for the fiscal year ending December 31, 2026.

Q: When and how will NuScale Power (SMR) hold its 2026 annual stockholder meeting?

The 2026 annual meeting will be held virtually on May 29, 2026, at 1:30 p.m. Pacific Time. Stockholders can attend, vote and ask questions online via www.virtualshareholdermeeting.com/SMR2026 using their 16-digit control number from proxy materials.

Q: Who is eligible to vote at NuScale Power’s (SMR) 2026 annual meeting?

All stockholders of record at the close of business on March 30, 2026, are entitled to vote. Beneficial owners must follow instructions from their bank or broker. Non-stockholders may attend as observers but cannot vote or ask questions during the virtual meeting.

Q: What is the Tax Receivable Agreement described in NuScale Power’s (SMR) proxy?

The Tax Receivable Agreement requires NuScale to share cash tax savings from basis step‑ups and related benefits following exchanges of NuScale Power, LLC Class B units. As of December 31, 2025, it produces an implied $582,178,000 obligation tied to exchanged units, including those previously held by Fluor.

Q: How could the Tax Receivable Agreement affect NuScale Power (SMR) in a change of control?

In an early termination or change-of-control scenario, NuScale estimates it could owe about $365,000,000 under the Tax Receivable Agreement, based on assumed full utilization of tax attributes. The filing notes this obligation could substantially impact liquidity and affect major strategic transactions.

Q: How independent is NuScale Power’s (SMR) board and its key committees?

The board has determined that a majority of directors, and all members of the Audit, Compensation, and Nominating and Governance Committees, are independent under NYSE and company standards. Audit Committee members are financially literate, and two qualify as “audit committee financial experts.”

Q: Where can investors find NuScale Power’s (SMR) 2025 Form 10-K and proxy materials?

The 2025 Annual Report to Stockholders and proxy materials are available at www.nuscalepower.com and via the SEC’s website at www.sec.gov. Stockholders may also request a free printed copy of the 2025 Form 10-K by writing to the Corporate Secretary at NuScale’s Corvallis, Oregon address.

Rhea-AI Filing Summary

NuScale Power Corporation is asking stockholders to vote at its 2026 virtual annual meeting on May 29, 2026. Investors will elect nine directors, cast a non-binding advisory vote on executive compensation and ratify Ernst & Young LLP as auditor for the year ending December 31, 2026.

The proxy describes a majority-independent board, fully independent key committees and extensive nuclear and energy-sector expertise among directors and nominees. It also highlights a Tax Receivable Agreement tied to exchanges of NuScale Power, LLC Class B units, with an implied obligation of $582,178,000 and an estimated $365,000,000 payment in an early termination or change-of-control scenario.

Positive

None.

Negative

Large potential Tax Receivable Agreement obligation: NuScale estimates an implied TRA obligation of $582,178,000 from exchanged NuScale Power, LLC Class B units and an estimated $365,000,000 payment exposure upon early termination or change of control, which the company warns could substantially impact liquidity and complicate major strategic transactions.

Insights

Routine governance items, but Tax Receivable Agreement could materially affect future liquidity.

NuScale outlines standard annual meeting business—director elections, a say-on-pay advisory vote and auditor ratification—within a board framework that is majority independent, committee-led and anchored by significant nuclear, energy and financial experience. These elements signal a conventional large‑accelerated‑filer governance profile.

The proxy gives extensive disclosure on a Tax Receivable Agreement linked to exchanges of NuScale Power, LLC Class B units into Class A shares. As of December 31, 2025, exchanges have produced an implied obligation of $582,178,000. An amendment cut Fluor’s share of net tax savings to 42.5%, raising NuScale’s retained percentage to 57.5%.

Under an early termination or change of control, NuScale estimates it could owe about $365,000,000 under this agreement, based on specified assumptions. The filing notes this could substantially impact liquidity and potentially influence large strategic transactions, even though no liability is currently recorded due to the company’s tax position.

Key Terms

Tax Receivable Agreement, change of control, audit committee financial expert, Large Accelerated Filer, +2 more

6 terms

Tax Receivable Agreement financial

"the Company entered into the Tax Receivable Agreement with NuScale Power, LLC, each of the TRA Holders..."

A contract in which a company agrees to pay a specified party (often former owners after a spinoff or IPO) a share of future tax savings the company realizes. Think of it like agreeing to share a future tax refund with someone who helped create the conditions for that refund. For investors it matters because those payments reduce the cash the company can use for dividends, buybacks, or reinvestment, and therefore affect valuation and returns.

change of control financial

"upon a change of control, the Company’s obligations under the Tax Receivable Agreement will accelerate..."

A change of control occurs when the ownership or management of a company shifts significantly, such as through a sale, merger, or acquisition, resulting in new leadership or ownership structure. This change can impact the company's direction and decision-making, which is important for investors because it may affect the company's stability, strategy, and future prospects.

audit committee financial expert regulatory

"at least one of NuScale’s directors qualifies as an “audit committee financial expert” as defined by the SEC"

A person on a company’s board who has deep knowledge of accounting, financial reporting and auditing, able to understand and question the books, controls and audit work like a trained mechanic inspecting an engine. Investors care because that expertise helps spot errors, weaknesses or misleading statements early, improving the likelihood that financial reports are accurate and reducing the risk of surprises that can hurt a company’s value.

Large Accelerated Filer regulatory

"2026 is the second year that NuScale is required to address the “Say on Pay” requirement in our filings as a Large Accelerated Filer."

A large accelerated filer is a publicly traded company that meets the U.S. securities regulator’s size and reporting history thresholds, qualifying it as one of the largest issuers. For investors, that label matters because such companies face faster filing deadlines, more rigorous audit and internal-control disclosure requirements, and generally more transparent and timely financial reporting—like a big, well-regulated store required to post its inventory and receipts promptly for customers to see.

Notice and Access regulatory

"We are electronically disseminating Annual Meeting materials... under the “Notice and Access” rules approved by the Securities and Exchange Commission."

Notice and access is a delivery method regulators allow for sending shareholders a brief paper notice that tells them where to find full meeting materials and voting forms online instead of mailing long paper packets. Investors can read documents, cast votes, or request a paper copy; it speeds delivery and cuts costs like receiving a postcard with a website link instead of a thick booklet. It matters because it affects how quickly and easily investors get information and vote, and may influence participation and record-keeping.

Section 754 of the Internal Revenue Code financial

"subsidiaries... annually elect under Section 754 of the Internal Revenue Code to adjust the tax basis..."

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 9

CORPORATE GOVERNANCE

NuScale’s corporate governance structure includes:

•all members of the Audit Committee, Organization and Compensation Committee (the “Compensation Committee”) and Nominating and Corporate Governance Committee (the “Nominating and Governance Committee”) are independent directors;

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

•the presiding director for executive sessions is the Board chair or the committee chair of the meeting where the executive session takes place;

•at least one of NuScale’s directors qualifies 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, which includes annual director training of NuScale’s policies and programs and a membership to the National Association of Corporate Directors (“NACD”) to assist them in remaining current with best practices and developments in board oversight and corporate governance, as well as opportunities to participate in NACD fellowship programs on leading boardroom practices and commitment to boardroom excellence.

Independence of the Board of Directors

The NYSE’s rules require that independent directors must comprise a majority of a listed company’s board of directors. Additionally, the Board’s Audit Committee, Nominating and Governance Committee and Compensation Committee must be comprised entirely of independent directors. The majority of our Board and all of our committees 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.

In accordance with NYSE listing standards and our Corporate Governance Guidelines, our Board determines annually which directors are independent and, through the Nominating and Governance Committee, oversees the independence of directors throughout the year. In addition to meeting the minimum NYSE standards of independence, a director qualifies as “independent” only if the Board affirmatively determines that the director has no material relationship with the Company (either directly, or indirectly as a partner, stockholder or officer of an organization that has a relationship with the Company).

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 10

A relationship is “material” if, in the judgment of the Board, the relationship would interfere with the director’s independent judgment.

Our Board has adopted director independence standards for assessing the independence of our directors. These criteria include restrictions on the nature and extent of any affiliations the directors and their immediate family members may have with us, our independent accountants, organizations with which we do business, other companies where our executive officers serve as Compensation Committee members and non-profit entities with which we have a relationship. Our independence standards are included in our Corporate Governance Guidelines, which are available at www.nuscalepower.com/investors/governance.

Based upon information requested from and provided by each of our directors concerning his or her background, employment and affiliations, including family relationships, the Board, as recommended by the Nominating and Governance Committee, has determined that each of the Company’s directors (other than Messrs. Collins and Hopkins) is independent of the Company and its management under NYSE listing standards and the standards set forth in our Corporate Governance Guidelines. Additionally, as Mr. James T. Hackett departed from the Board in January 2025, it was previously affirmatively determined that Mr. Hackett was also an independent director under NYSE listing standards and the standards set forth in our Corporate Governance Guidelines during his term as a director. The Board also determined that each of the members of the Audit Committee and Compensation Committee satisfies the enhanced independence standards applicable to members of such a committee under the NYSE standards and our director independence standards for such committee. Mr. Hopkins is not independent because of his employment as President and Chief Executive Officer of the Company. Mr. Collins is not independent because of his current employment with Fluor.

Additionally, based upon information requested from and provided by each of our two new director nominees concerning his background, employment and affiliations, including family relationships, the Board, as recommended by the Nominating and Governance Committee, has determined that each of Messrs. Harshaw and Klein is independent of the Company and its management under NYSE listing standards and the standards set forth in our Corporate Governance Guidelines.

Finally, the Board reviewed charitable contributions made to non-profit organizations for which Board members (or their respective spouses) serve as an executive officer or on the board of directors of such non-profit. No organization received contributions in a single year in excess of the greater of 2% of such non-profit’s consolidated gross revenues or $100,000, which falls below the threshold of the Company’s independence standards.

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 11

Board Leadership Structure

The Board has determined that our current structure of separating the roles of Chairman of the Board and Chief Executive Officer is in the best interests of our Company and our stockholders. Mr. Boeckmann has served as Chairman of the Board since January 2025 following the departure of Mr. Hackett from the role of non-executive Chairman of the Board; and Mr. Hopkins has been the Chief Executive Officer of our Company since December 2012. As Chairman of the Board, Mr. Boeckmann focuses on organizing Board activities to enable our Board to effectively provide guidance to and oversight (including risk oversight) and accountability of management. The Chairman of the Board, among other things, creates and maintains an effective working relationship with the Chief Executive Officer and other members of management and with the other members of our Board, provides the Chief Executive Officer ongoing direction regarding Board needs, interests and opinions, and ensures our Board agenda is appropriately directed toward matters significant to our Company. Separating the roles of Chairman of the Board and Chief Executive Officer allows Mr. Hopkins, as Chief Executive Officer, to focus on managing the day-to-day direction and implementing the long-term strategic goals of our Company.

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 each of its committees about their respective risk oversight activities. In its risk oversight role, the Board and each of its committees regularly review and discuss, internally and with management, the material short-, intermediate-, and long-term risks confronting our business, based on reports prepared and delivered by management and outside advisors that address these risks and other information deemed relevant. The Audit Committee periodically reviews NuScale’s risks relating to accounting, reporting and financial practices, including the integrity of its financial statements, the surveillance of administrative and financial controls, compliance with legal and regulatory requirements, and information system controls and cybersecurity-related matters. The Audit Committee also oversees our enterprise risk management program, which includes the review of operational issues, such as supply chain risks. 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 Nominating 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 Compensation Committee also has a role in risk management and mitigation by ensuring

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 12

that the Company’s compensation philosophy and programs do not induce excessive risk-taking by management and instead reward good stewardship of stockholder investments.

Board Committees

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

Our President and Chief Executive Officer and other executive officers regularly report to the non-executive directors and the Audit, Compensation, Nominating and Governance and Executive Committees to ensure effective and efficient oversight of our activities and to assist in proper risk management and the ongoing evaluation of management controls.

Audit Committee

Our Audit Committee is composed of Messrs. Kresa (chair) and Fujino and Ms. Walters. 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 Exchange Act. Mr. Kresa and Ms. Walters qualify as “audit committee financial experts” as defined in Item 407(d)(5) of Regulation S-K and possess financial sophistication, as defined under the rules of the NYSE.

The purpose of the Audit Committee is 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 preparing the audit committee report required by the SEC to be included in NuScale’s proxy statement, reviewing the adequacy and effectiveness of the Company’s internal controls, including computerized information system controls and cybersecurity. The Audit Committee also reviews, approves and oversees any transaction between the Company and any related person (as defined in Item 404 of Regulation S-K) and any other potential conflict of interest situations on an ongoing basis, and develops policies and procedures for the Audit Committee's approval of related party transactions. There were eight meetings of the Audit Committee in 2025.

The Audit Committee has a written charter that is available on our website, www.nuscalepower.com.

Organization and Compensation Committee

Our Compensation Committee is composed of Messrs. Boeckmann (chair) and Kresa and Ms. Warnica. The purpose of the Compensation Committee is to assist the Board in discharging its responsibilities

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 13

relating to the review and determination of executive compensation, including (1) setting our compensation program and the compensation of our executive officers and directors and (2) monitoring our incentive and equity-based compensation plans. Among its other responsibilities, the Compensation Committee provides the Compensation Committee report required by SEC rules, reviews, approves and recommends to the Board for approval, employment agreements and severance arrangements or plans with executive officers, periodically reviews management’s officer and executive succession plan, and generally oversees the Company's strategic employment and workplace policies, practices and outcomes. As discussed in the Director Compensation and Executive Compensation sections below, the Compensation Committee has retained FW Cook, an independent compensation consultant, as its advisor (“Compensation Consultant”). The Compensation Committee also has the authority to delegate any of its responsibilities, along with the authority to take action in relation to such responsibilities, to one or more subcommittees as it may deem appropriate. There were six meetings of the Compensation Committee in 2025.

Our Compensation Committee has a written charter that is available on our website, www.nuscalepower.com.

Nominating and Governance Committee

Our Nominating and Governance Committee is composed of Ms. Warnica (chair) and Messrs. Boeckmann and Chung. The purpose of the Nominating and Governance Committee is to assist the Board in discharging its responsibilities relating to the Company’s director nominations process and procedures, developing and maintaining the Company’s corporate governance policies and any related matters required by the federal securities laws. Among its other responsibilities, the Nominating and Governance Committee (1) identifies individuals qualified to become new members of the Board, consistent with criteria approved by the Board, (2) reviews the qualifications of incumbent directors to determine whether to recommend them for reelection and selects or recommends that the Board select, the director nominees for the next annual meeting of stockholders, (3) identifies potential members qualified to fill vacancies on any Board committee and recommends that the Board appoint the identified member or members to the applicable committee, (4) reviews and recommends to the Board corporate governance principles applicable to NuScale, and (5) oversees the evaluation of the Board and management. There were five meetings of the Nominating and Governance Committee in 2025.

Our Nominating and Governance Committee has a written charter that is available on our website, www.nuscalepower.com.

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 14

Executive Committee

The Board has established an Executive Committee, comprised of the Board Chairman, NuScale’s President and Chief Executive Officer, and the Chairs of the other three standing committees: Audit, Compensation and Nominating and Governance. Mr. Boeckmann, as Board Chairman and Chair of a standing committee, Mr. Hopkins, as NuScale’s President and Chief Executive Officer, Mr. Kresa and Ms. Warnica, as Chairs of the remaining standing committees, are the current members of the Executive Committee. There were nine meetings of the Executive Committee in 2025. 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.

Special Committee

Our Special Committee was composed of Messrs. Kresa (chair) Chung and Fujino. The purpose of the Special Committee was to evaluate Fluor Corporation’s monetization alternatives for its equity position in the Company. There were 20 meetings of the Special Committee in 2025. The Special Committee was established in July 2025 and disbanded in February 2026 following execution of the Exchange Agreement with Fluor on November 6, 2025.

Director Criteria

Pursuant to the Nominating and Governance Committee charter, the Nominating and 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. While satisfying the foregoing director criteria serves as gating criteria for new candidates, the Nominating and Governance Committee may also consider as appropriate important factors, including character, judgement, leadership, and different perspectives and backgrounds (including without limitation, age, gender, and ethnicity). The Nominating and Governance Committee, to date, has not paid a consultant to assist it in identifying Board candidates. The Nominating and Governance Committee identified both Mr. Harshaw and Dr. Klein as new director candidates following a review of their qualifications against Board membership criteria and desired skills and conducting multiple interviews.

The Company does not have a policy on stockholder nominations for directors. Section 2.10 of the Company’s Amended and Restated Bylaws (the “Bylaws”) outlines procedures for stockholders to submit nominations for election to the Board of Directors.

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 15

Director Time Commitments

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 should advise the Chair of the Nominating and 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 Nominating and Governance Committee and 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.

Board and Committee Evaluations

In order to monitor and improve their effectiveness, and to solicit and act upon feedback received, the Board and its committees, under the oversight of the Nominating and Governance Committee, engage in an annual formal self-evaluation process. As part of the self-evaluation process, directors consider various topics related to Board composition, structure, effectiveness and responsibilities. While the Board and each of its committees conduct the self-evaluations annually, the Board considers its performance and that of its committees throughout the year and shares feedback with management.

Code of Business Ethics

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 business ethics is available on our website at www.nuscalepower.com. The code of business ethics is a “code of ethics,” as defined in Item 406(b) of Regulation S-K. We will make any legally required disclosures regarding amendments to, or waivers of, provisions of its code of business ethics on our website.

Employee, Officer and Director Hedging

Our Insider Trading Policy and Insider Trading Procedure, which applies to all employees, officers and directors, prohibits transactions that hedge or offset decreases in the value of NuScale securities.

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 16

Insider Trading Policy and Procedures

Our Insider Trading Policy and Insider Trading Procedure govern the purchase, sale and/or other disposition of NuScale securities by directors, officers and employees. We believe our Insider Trading Policy and Insider Trading Procedure are reasonably designed to promote compliance with insider trading laws, rules and regulations and NYSE listing standards. These documents also state that it is NuScale’s policy to comply with insider trading laws with respect to trading in its own securities. Our Insider Trading Policy and Insider Trading Procedure are filed as Exhibit 19.1 and 19.2, respectively, to our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

Certain Relationships and Related Person Transactions

Fluor Enterprises, Inc.

As of the date of this proxy statement Fluor Enterprises, Inc. is a related person of the Company, as defined by the securities regulations (a “Related Person”), by virtue of beneficially owning more than five percent of the issued and outstanding shares of the Company’s Class A common stock, $0.0001 par value per share (“Class A common stock”). From January 1 through December 31, 2025, Fluor Transworld Services, Inc., a subsidiary of Fluor Enterprises, Inc., has made payments totaling $22,124,860.16 to NuScale Power, LLC for engineering, design and other services pursuant to a Master Services Agreement, dated January 25, 2021.

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 17

Tax Receivable Agreement

NuScale Power, LLC and each of its subsidiaries classified as a partnership or a disregarded entity for United States federal income tax purposes annually elect under Section 754 of the Internal Revenue Code (the “Code”) to adjust the tax basis of the assets of NuScale Power LLC in the tax year a share exchange occurs. The annual election will remain in effect for any future tax year in which an exchange of NuScale Power, LLC Class B Units for shares of the Company’s Class A common stock under the Sixth Amended and Restated Limited Liability Company Agreement of NuScale Power, 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 4.1, “Description of Registrant’s Securities,” to the Company’s 2025 Annual Report on Form 10-K. Such elections are expected to increase the tax basis of the tangible and intangible assets of NuScale Power, LLC. Such increases in the tax basis of the tangible and intangible assets of NuScale Power, LLC, as well as other tax benefits, may reduce the amount of tax the Company 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 any such challenge may be sustained by a court.

In connection with the closing in 2022 of the merger transaction by which NuScale Power, LLC became a subsidiary of the Company (the “Closing”), the Company entered into the Tax Receivable Agreement with NuScale Power, LLC, each of the TRA Holders (as defined in the Tax Receivable Agreement) party thereto, and Fluor Corporation, in its capacity as TRA Representative (as defined in the Tax Receivable Agreement). Pursuant to the Tax Receivable Agreement, the Company 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 Power, LLC Class B Units for shares of Class A common stock or cash in the future. The Company’s obligations under the Tax Receivable Agreement accelerate upon a change in control and certain other termination events, as defined therein.

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

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 18

On November 6, 2025, the Company and Fluor executed an amendment to the Tax Receivable Agreement (the “TRA Amendment”), whereas the percentage of net cash tax savings from certain tax benefits was reduced by 50% to 42.5%, while the benefit percentage retained by the Company increased from 15% to 57.5%. For the avoidance of doubt, the TRA Amendment does not reduce the benefit percentage of any other party to the TRA.

The term of the Tax Receivable Agreement will continue until all such tax benefits have been utilized or expired, unless the Company 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 the Company breaches any of its material obligations under the Tax Receivable Agreement, in which case all obligations will generally be accelerated and due as if the Company 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 Power, LLC, as well as the amount and timing of any payments under the Tax Receivable Agreement, will vary depending upon several factors, including:

1.the timing of exchanges of NuScale Power, 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 Power, 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 Power, 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% (42.5% for Fluor) of the cash tax savings, if any, as and when realized.

If the Company does not have taxable income (determined without regard to the tax basis and other tax benefits that are subject to the Tax Receivable Agreement), the Company 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

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 19

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 Power, LLC Class B Units for shares of Class A common stock under the A&R NuScale LLC Agreement could be substantial. It is possible that additional 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 the Company’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 the Company by NuScale Power, LLC are not sufficient to permit the Company to make payments under the Tax Receivable Agreement after the Company has paid its taxes. The payments under the Tax Receivable Agreement are not conditioned upon the TRA Holders’ continued ownership of securities of the Company or NuScale Power, LLC. As of December 31, 2025, there have been 158,983,526 NuScale Power, LLC Class B Units exchanged, out of which 125,936,472 were exchanged by Fluor Corporation during 2025, (together with the cancellation for no consideration of an equal number of shares of the Company’s Class B common stock, $0.0001 par value per share (“Class B common stock,” and together with Class A common stock “common stock”)) for shares of Class A common stock. As of December 31, 2025, 100% of Fluor Corporation’s NuScale Power, LLC Class B Units have been exchanged. Associated with these exchanged units we have calculated an implied Tax Receivable Agreement obligation of $582,178,000 as of December 31, 2025. However, given the Company's current tax situation, we conclude the liability is not probable, and thus no liability related to projected obligations under the Tax Receivable Agreement has been recorded.

In addition, the Tax Receivable Agreement provides that upon a change of control, the Company’s obligations under the Tax Receivable Agreement will accelerate as if the Company had exercised its early termination right based on certain assumptions (as described below), including that the Company 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.

Furthermore, the Company 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 Power, 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) the Company will have sufficient taxable income in each future taxable year to fully utilize all relevant tax attributes subject to the Tax

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 20

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 is discounted at a rate equal to the lesser of (i) 6.5% and (ii) the London Inter-Bank Offer Rate plus 400 basis points.

As a result of either an early termination or a change of control, the Company could be required to make payments under the Tax Receivable Agreement of an estimated $365,000,000 as of December 31, 2025. This payment could exceed our actual cash tax savings. While analysis performed during 2025 indicates no deemed early termination has occurred, 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 the Company 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 Power, LLC to distribute the needed funds. To the extent that the Company 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 the Company’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

The Company has entered into indemnification agreements with each of its executive officers and directors. The indemnification agreements and our certificate of incorporation, as amended and the Bylaws require that the Company indemnify its directors to the fullest extent not prohibited by Delaware law. Subject to certain limitations, the Bylaws also require us to advance expenses incurred by our directors and officers. The Company 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, the Company and certain securityholders of the Company and NuScale Power, LLC, 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

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 21

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 June 2, 2023. Underwriting discounts and selling commissions for sales pursuant to the registration statement were borne by the securityholders. The Registration Rights Agreement contains customary cross-indemnification provisions under which the Company must indemnify holders of registrable securities for material misstatements or omissions in the registration statement attributable to the Company, and holders of registrable securities must indemnify the Company 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

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 22

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 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.

“Say on Pay”

2026 is the second year that NuScale is required to address the “Say on Pay” requirement in our filings as a Large Accelerated Filer. That proposal is addressed on page 58 in this proxy statement.

Overview of 2025 Business Context and Performance

In 2025, we continued our focus on customer acquisition, operational excellence, safety and financial discipline, allowing the Company to remain healthy and positioned for sustainable stakeholder value creation.

We continue to progress towards our goal of acquiring a new Class 1 commercial customer. Our financing cash flows remained strong, and we believe that the resulting cash and investment balances at the end of 2025 positions us to be able to implement the actions needed as we continue our commercialization efforts within the Company. In the nuclear industry, safety is always paramount, and our safety record is exceptional.

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.

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 28

Summary of Compensation Philosophy and Policies

Establishing Executive Compensation

The Compensation Committee has responsibility for establishing and implementing the Company’s executive compensation philosophy. The Compensation Committee, with the advice of its Compensation Consultant, reviews and determines all components of NEOs’ compensation (other than for the President and Chief Executive Officer, which the Compensation Committee reviews and recommends for approval by our Board, except our President and Chief Executive Officer). This includes individual compensation decisions as well as reviewing and revising the Company’s compensation program and practices.

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

•safeguard against imprudent risk-taking.

Our Approach

Align the interests of NEOs with those of the stockholders.

The Compensation Committee believes it is appropriate to tie a significant portion of executive compensation to the value of the Company’s stock performance to closely align the interests of NEOs with those of our stockholders. The Compensation Committee also believes that NEOs should have a meaningful ownership interest in the Company and, as such, maintains and regularly reviews NEO stock ownership guidelines.

Have a significant portion of pay that is performance-based or at risk.

NuScale expects superior performance from our executives. Our executive compensation programs are designed to reward executives when performance results for the Company and the executive meet or exceed stated objectives. As a result, the majority of our executive compensation program is at-risk, meaning that pay delivery varies directly with the performance of the company.

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 29

Provide competitive compensation.

The Company’s executive compensation programs are designed to attract, retain and motivate highly qualified executives critical to achieving NuScale’s strategic objectives and building stockholder value.

The Compensation Committee reviews the Company’s compensation philosophy and objectives each year to determine if revisions are necessary considering market conditions, the Company’s strategic goals or other relevant factors. In each of the last five years, the Compensation Committee determined that no revisions to the executive compensation philosophy and objectives were necessary, although the Compensation Committee has adjusted the specific elements of compensation used to implement its philosophy as the business and operating environment have evolved.

In addition, the Compensation Committee reviewed the incentive compensation we provide to our executives, including our NEOs, and evaluated the mix of plans and performance criteria, the Compensation Committee’s ability to exercise discretion over certain components of compensation and our risk management practices in general. Based on this review, the Compensation Committee believes that our compensation program is designed to appropriately align compensation with our business strategy and not to encourage behavior that could create material adverse risks to our business.

Role Of Independent Compensation Consultant

The Compensation Committee has the authority under its charter to engage the services of outside legal counsel, compensation consultants and other advisors. In 2025, the Compensation Committee again engaged FW Cook to serve as its independent compensation consultant to advise the Compensation Committee on all matters related to executive and Board of Director compensation, and thus, conducts an annual review of the respective total compensation programs.

In 2025, as part of the Compensation Committee’s oversight of certain aspects of risk, the Compensation Consultant also conducted a risk assessment of the Company’s compensation program and discussed its findings with the Compensation Committee, indicating that it believes the Company’s compensation programs do not encourage behaviors that would create material risk for the Company. Additionally, the Compensation Consultant provided written and verbal advice at Compensation Committee meetings, attended executive sessions of the Compensation Committee to respond to questions, and had individual calls and meetings with the chair of the Compensation Committee to provide advice and perspective on executive compensation issues. The Compensation Consultant was engaged by, and reports directly to, the Compensation Committee and does not perform any other services for the Company. The Compensation Committee has determined that the Compensation Consultant’s engagement does not raise any conflicts of interest.

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 30

Peer Group Comparisons

In making compensation decisions, the Compensation Committee looks at the practices of our peer group. The Committee annually reviews the composition of the peer group with the Compensation Consultant and makes refinements, if necessary, based on objective criteria established by the Compensation Committee.

The Compensation Committee has applied a generally consistent process and set of criteria for selection of the peer group. Potential peer companies were identified by assessing our direct competitors and key customers, companies with which we compete for executive talent and companies with generally comparable pay models. Peers were generally selected from the broader technology hardware industry, with a preference for those in electrical/energy technology, and nuclear technology. The Compensation Committee also generally selected companies with market capitalizations ranging from 0.20x to 5.0x that of the Company, and those with revenues of less than $1.0 billion.

The Compensation Committee reviews benchmarking comparisons prepared by its compensation consultant for each NEO against similar positions within the peer group.

For 2025, the Compensation Committee determined that the peer group should consist of the following companies:


2025 Peer Group
Archer Aviation Ballard Power Blink Charging Bloom Energy Centrus Energy ChargePoint Energy Fuels	Enovix Eos Energy ESS Tech EVgo FuelCell Energy Hyliion Holdings Joby Aviation	Montauk Renewables Plug Power Shoals Technologies Stem Sunnova Energy

For 2026, the Compensation Committee determined that the peer group selection criteria should be updated. The new criteria included companies with market capitalizations up to 3x that of the Company, and those with revenues of less than $1.0 billion. The companies comprising our peer group for purposes of establishing 2026 compensation were:

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 31


2026 Peer Group
Archer Aviation Ballard Power Bloom Energy Centrus Energy Clearway Energy Energy Fuels	Enovix Enphase Energy Eos Energy EVgo Joby Aviation Oklo	Ormat Technologies Plug Power QuantumScape Shoals Tech Uranium Energy

Role Of Company Management In Compensation Decisions

Before the Compensation Committee makes decisions on executive compensation, the President and Chief Executive Officer reviews compensation for the NEOs (other than himself), and makes recommendations to the Compensation Committee based on their individual and group performance. The Compensation Committee Chair, in consultation with the Compensation Consultant, reviews the President and Chief Executive Officer’s compensation and makes recommendations to the Compensation Committee for approval. Specifically, the President and Chief Executive Officer proposes to the Compensation Committee current year base salary adjustments and target annual and long-term incentive awards for each of the other NEOs. In addition, the Compensation Committee reviews and approves the compensation actually paid to the NEOs (other than the President and Chief Executive Officer, which is approved by the full Board) after consideration of the recommendations made by the President and Chief Executive Officer.

The independent members of the Board assess the President and Chief Executive Officer’s performance each year, determine the President and Chief Executive Officer’s annual incentive payout for the prior year and set target total direct compensation for the following year, including any base salary adjustment and target annual and long-term incentive awards.

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 32

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 2025. This discussion may contain forward-looking statements that are based on NuScale’s current plans, considerations, expectations and determinations regarding future compensation programs.

Our compensation program includes the following pay delivery components:

•Base salary that is competitive in our labor market and industries in which we operate as well as our peer group.

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

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

Compensation Mix Supports Pay-For-Performance

In making decisions regarding the compensation opportunities for the NEOs for 2025, the Compensation Committee took into account market conditions and performance, and also considered market data for our compensation peer group.

The Compensation Committee took the following specific actions with respect to NEO compensation for 2025:

•Increased base salaries for some of the NEOs to better align with similar positions in our peer group and maintain the competitiveness of our overall compensation program.

•Annual incentives for NEOs were paid in cash and based on the achievement of established sales, financial, operational, safety and strategic goals for 2025.

•Granted long-term incentive awards in the form of time vested RSUs. In addition, the Compensation Committee targeted equity grant levels at the 50th percentile of industry peers.

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 33

A summary of our program and its link to performance is shown below:

Cash Incentives


Component	Primary Purpose	Linkage to Performance
Base Salaries	•Provide a market competitive, stable level of income to attract and retain top talent.	•Individual contributions to the Company, salary movement in the peer group and internal pay equity are considered in determining initial salary levels and any subsequent adjustments.
Annual Bonus Incentives	•Provide annual cash compensation for achievement of established performance goals.	•Based on Company achievement of near-term objectives that support long-term value creation, including: Commitments to Purchase New Modules, Cash Revenues, Completion of Work Scopes, Execution of Projects, Final Approval of SDAA, Safety Objectives and Workforce Strength Objections. •Completely at risk, depending on actual performance against the established targets.

Long-Term Equity Incentives


	Primary Purpose	Linkage to Performance
Restricted Stock Units	•Provide a long-term equity ownership and retention vehicle that is directly linked to stockholder value over time	•Vest ratably over three years, aligning the interest of the NEOs with those of stockholders by focusing NEOs on the Company's stock price performance. •Value is at risk, increasing or decreasing with the stock price over the vesting period.

Long-term incentives comprise the biggest portion of our NEO annual compensation opportunity and align our leadership team with stockholders. Our long-term incentive plan is also time vested over a multi-year period, further incentivizing decisions that are in the best long-term interest of the Company, leadership team and stockholders.

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 34

Compensation Governance Highlights

Our executive compensation policies reflect our strong focus on sound governance. As in prior years, the following practices and policies were in effect during 2025:


What We Do						What We Do Not Do
•Maintain robust stock ownership guidelines for executive officers and directors, including a 5x base salary requirement for the President and Chief Executive Officer. •Provide a balanced program design that does not encourage behavior that could create material adverse risks to our business. •Conduct an annual compensation risk assessment. •Change-in-control policy requires double-trigger events. •Engage an independent compensation consultant to advise the Compensation Committee. •Maintain a robust clawback policy.						•No excise tax gross-ups in change-in-control policy. •No repricing of stock options without stockholder approval. •No hedging, pledging and short-term trading of Company stock. •Reward executives for excessive, inappropriate or unnecessary risk-taking. •Provide excessive perquisites. •Provide guaranteed bonuses or uncapped incentives.

Cash Components of 2025 NEO Compensation

Base Salaries

The Company provides NEOs with base salaries for a competitive, stable level of income, since other elements of their direct compensation are at-risk based on Company performance. The Compensation Committee reviews base salaries for NEOs annually and upon a change in responsibilities.

In establishing and annually evaluating base salary levels, the Compensation Committee and, with respect to the President and Chief Executive Officer, the directors of the Board (other than the President and Chief Executive Officer), consider the following factors:

•Peer group data and energy industry survey data for comparable positions prepared by the Compensation Committee’s independent consultant, targeting the 50th percentile of our peer group;

NuScale Professional Incentive Compensation Plan

We adopted the NuScale Professional Incentive Compensation Plan on January 1, 2015, to focus senior staff, managers and other personnel designated by our President and 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 include Company performance measures. We set threshold, target and maximum incentive payment amounts by job classification. Typically, plan participants are identified and Company performance measures are proposed by our President and Chief Executive Officer and approved by our Compensation Committee.

The Board approves goals and weightings for those goals at the beginning of each calendar year and a cash incentive bonus is paid annually based on the level of management’s achievement of those goals. The weightings applied to each goal are in proportion to the Board’s assessment of the importance of each goal to overall Company success.

Cash-based annual incentives are provided to motivate and reward NEOs for achieving annual performance objectives. In 2025, each of the NEOs participated in the annual incentive award program and had a target annual incentive amount established as a percentage of annual base salary. This target opportunity reflects each NEO’s respective organizational level, position and responsibility for achievement of the Company’s financial and strategic goals and aligns with market practice.

NEOs could receive from zero to 200% of their target annual incentive amounts, depending on the extent to which applicable performance goals were achieved. The metrics, relative weightings and goals are determined by the Compensation Committee and approved by the Board each year. When determining performance measures and goals, the Compensation Committee considers the Company’s annual operating plan and strategic priorities for the year. For 2025, a combination of objective financial targets and strategic and safety performance measures were used. Target levels of achievement were tied to goals established in the first quarter of the year. The use of multiple financial operational, sales and safety goals prevents an overemphasis on any one financial metric and focuses the NEOs on key areas of importance to the Company and its stockholders.

In 2025, the Board adopted seven NuScale Professional Incentive Compensation Plan goals for management related to:

Commitments to Purchase New Modules, Cash Revenues, Completion of Work Scopes, Execution of Projects, Final Approval of SDAA design, Safety Objectives and Workforce Strength Objectives.

In February 2026, the Compensation Committee assessed management’s performance against these 2025 incentive goals and the Board determined that the Company’s performance resulted in a payout of 80.5% percent of target, which the Company paid to bonus-eligible employees, including the NEOs, in March 2026.

Average Annual Incentive Earned by NEOs

Below is the table showing the overall payout (percentage of target) for our executives from 2022-2025.

Long-Term Incentive Plan

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

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

For 2025, the Compensation Committee recommended and the Board approved a compensation program targeted at the 50th percentile of industry peers for the equity portion of the compensation package for our executives, which was endorsed by our Compensation Consultant.

As a public company, NuScale has traditionally granted 100% time-vested restricted stock units (“RSUs”) as our equity-based compensation vehicle and did so again in 2025. The one exception was in 2024, when the Company granted a combination of stock options and restricted stock units. Options were granted so that pay delivery would only be provided for an increase in the stock price, after the stock had experienced a meaningful decline at the time. RSUs vest ratably 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 in addition to RSUs and stock options.

It is the Company’s practice to issue annual equity awards in February each year. The exercise or grant price of any relevant equity-based award cannot be less than the closing price of our common stock on

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 40

the grant date, and our annual long-term incentive equity-based awards are granted only with the approval of the Compensation Committee or Board. We do not time the disclosure of material nonpublic information for the purpose of affecting the value of equity-based awards granted to our employees.

For ad hoc grants to new hires, the Senior Director, Human Resources, the President and Chief Executive Officer and the Compensation Committee will consider a variety of factors, including the executive’s level of responsibility, expected contributions to performance 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.

Ownership Requirements

Executive officers are required to hold stock with a market value equal to a multiple of their base compensation, as indicated below.

•President and Chief Executive Officer 5x base salary

•CFO and other Direct Reports of President and Chief Executive Officer 2x base salary

Equity that counts towards the guideline includes all shares owned directly or indirectly (by a spouse or trust), all shares of restricted stock, all shares underlying vested but unsettled time-vesting RSUs and 50% of the shares underlying unvested time-vesting RSUs. Unexercised options and unvested performance shares do not count toward the guideline.

Severance Arrangements

The Company maintains a severance policy (or in the case of our President and Chief Executive Officer, an employment agreement), pursuant to which each of our executives, including the NEOs, would be eligible to receive certain cash separation payments and other benefits in the event of a qualifying termination of their employment. We believe this policy supports talent recruitment, assists us in attracting and retaining qualified executives, and provides a consistent approach to departures.

In addition, the Company maintains a change in control plan that provides additional payments and other benefits if an executive incurs a qualifying termination of employment within a specified time following a change in control of the Company. The change in control plan (or similar provisions in our President and Chief Executive Officer’s employment agreement) is intended to support a smooth transition during a

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 41

merger or transaction by easing concerns over job security, to encourage the continued dedication of our executives amidst potentially disruptive circumstances, to incentivize executives to actively pursue transactions that would benefit stockholders, and to align the interests of executives with those of the Company’s stockholders. All potential change in control payments are “double trigger,” such that a NEO must incur a qualifying termination of employment following a change in control to be eligible for these payments, and we do not provide for any change in control excise tax gross-up payments.

Details of these arrangements are discussed under “Executive Employment Agreement, Executive Severance Policy and Executive Change in Control Plan.”

Clawback Policy

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

Anti-Hedging and Pledging

We have an anti-hedging/pledging policy that prohibits hedging, pledging and similar transactions that would minimize the risks of stock ownership.

Compensation Committee Interlocks and Insider Participation

No member of the Compensation Committee was at any time during fiscal year 2025, 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.

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 42

Organization & Compensation Committee Report

Management of the Company has prepared the Compensation Discussion and Analysis as required by Item 402(b) of Regulation S-K, and the Compensation Committee has reviewed and discussed it with management. Based on this review and discussion, the Compensation Committee recommended that the Compensation Discussion and Analysis be included in the proxy statement for the Annual Meeting.

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

Employment Agreement for John L. Hopkins

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, Mr. Hopkins will be entitled to severance consisting of (i) a lump sum equal to one year’s base salary plus target bonus; (ii) a pro-rated portion of the current year’s annual bonus; (iii) continued medical, dental and vision coverage for up to 18 months; (iv) reimbursement of outplacement services expenses incurred in the 12 months following termination up to $25,000; (v) 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; (vi) any performance-

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 48

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 the executive worked during the performance period; and (vii) 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 any performance-based awards and, with respect to any 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 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 the 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 the 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 the successor to assume the employment agreement or breach of same).

NuScale’s obligation to make the severance payments, and Mr. Hopkins’ 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 agreement contains (i) a perpetual confidentiality covenant; (ii) noncompetition 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 Mr. Hopkins’ 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

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 49

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 at target levels.

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

Executive Severance Policy

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 President and Chief Executive Officer’s employment agreement 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.

Executive Change in Control Plan

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 (based on the executive’s title); (ii) a prorated annual bonus at target; (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 President and Chief Executive Officer’s employment agreement 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

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 50

(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 following restrictive covenants: (i) a perpetual confidentiality covenant; (ii) noncompetition 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 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 at target levels.

Mr. Hopkins’ employment agreement and the executive change in control plan and severance policies provide that, if payments to an executive pursuant to any of these instruments (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 280G 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 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.

Termination Due to Death

In case of death, the executive’s beneficiary would receive a payout equal to the earned but unpaid portion of the deceased’s salary at the time of death, any earned but unused vacation accrued, a prorated portion of the deceased’s annual bonus at target and 18 months of COBRA reimbursement.

CEO Pay Ratio

Pursuant to the Securities Exchange Act of 1934, as amended, we are required to disclose in this proxy statement the ratio of the total annual compensation of our CEO to the median of the total annual compensation of all of our employees (excluding our CEO). Based on SEC rules for this disclosure and applying the methodology described below, we have determined that our CEO’s total annual compensation for 2025 was $4,084,073, and the total annual compensation for 2025 of our median compensated employee (excluding our CEO) was $180,332. Accordingly, we estimate the ratio of our CEO’s total annual compensation for 2025 to the total annual compensation for 2025 of our median compensated employee to be 23 to 1.

We identified the median compensated employee by taking into account the total taxable compensation for 2025 for all individuals, excluding our CEO, who were employed by us on December 31, 2025. We did not make any assumptions, adjustments or estimates with respect to their total taxable compensation for 2025, and we did not annualize the compensation for any employees who were not employed by us for all of 2025.

Once the median compensated employee was identified as described above, that employee’s total annual compensation for 2025 was determined using the same rules that apply to reporting the compensation of our Named Executive Officers (including our CEO) in the “Total” column of the Summary Compensation Table. The total compensation amounts included in the first paragraph of this pay-ratio disclosure were determined based on that methodology.

This pay ratio is an estimate calculated in a manner consistent with SEC rules based on the methodology described above. The SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions. As such, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

(3) Cumulative TSR is calculated based on the value of an initial fixed investment of $100 on May 2, 2022 (the date of the Closing), assuming reinvestment of dividends.

(4) The peer group used for calculating peer group TSR consists of publicly traded companies in the nuclear or energy transition industries comprised of Ballard Power Systems Inc., Bloom Energy Corporation, BWX Technologies, Inc., Enphase Energy, Inc., Enovix Corporation, FuelCell Energy, Inc., Plug Power Inc., Oklo Inc. and SolarEdge Technologies, Inc.

Director Compensation

Compensation for Board service includes an annual $80,000 cash retainer (or stock equivalent); plus $50,000 (or stock equivalent) for the non-Executive Chair of the Board; and $30,000 (or stock equivalent) for the Lead Independent Director if one is appointed separate from the non-Executive Chair of the Board. All amounts are payable quarterly in arrears.

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 54

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


Committee(1)	Member	Additional to Chair
Audit	$ 10,000	$ 12,500
Compensation	$ 7,500	$ 8,000
Nominating and Governance	$ 5,000	$ 6,500
(1) Directors who are employed by us or Fluor are not compensated for their services.

In addition, the Special Committee was formed on July 27, 2025 and disbanded on February 24, 2026. The Special Committee members received a quarterly retainer of $25,000. Finally, the non-employee directors are each granted (i) time-based Restricted Stock Unit (“RSU”) awards with a grant value equal to $110,000 annually, that vest quarterly over one year, and (ii) 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 the Compensation Consultant to help it develop the compensation plan described above. The Compensation Consultant was retained by the Company at the direction of the Compensation Committee. The Compensation Committee directs when the Compensation Consultant is engaged. Since the initial engagement, the Compensation Consultant has been providing recommendations regarding executive compensation and Board compensation.

The Compensation Consultant provides competitive data and makes recommendations to the Board on pay levels and program structure. The last review was conducted in February 2023, at which time, the Board approved an increase of $30,000 to the annual RSU award, bringing the program to the median of a group of comparable peer companies.

No additional changes were made to the program for fiscal 2024 and for fiscal 2025. For fiscal 2026, as approved in November 2025, the Board adopted the Deferred Compensation Plan, allowing directors to defer up to 100% of annual cash and equity compensation until termination from the Board.

Ownership Requirements

Non-employee and non-Fluor directors are required to acquire and retain the net after-tax shares received as compensation until accumulated holdings have a market value equal to 5x annual cash retainer.

Summary Director Compensation Table

The following table shows the total compensation paid, as well as the grant date fair value of all equity awards granted, during the fiscal year ended December 31, 2025, to each of our non-employee directors. Directors who are employed by us or Fluor are not compensated for their service on our Board.

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 eight members, five of whom have served since May 2022, when we completed the Closing, with two members being appointed in December 2022, one member being appointed in December 2023 and one member being appointed in December 2024. We have jointly agreed with Alvin Collins, III, that he will not stand for re-election at the Annual Meeting.

Our Board has nominated two additional directors for election at the Annual Meeting, Mr. Harshaw and Dr. Klein, and approved an increase in the size of the Board to nine directors. Each nominee 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 the individuals that our Board has nominated to serve as directors:

PROPOSAL 2: ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION


PROPOSAL 2: ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION

We are asking stockholders to vote on an advisory resolution to approve the Company’s executive compensation as reported in this proxy statement.

We urge stockholders to read the “Compensation Discussion and Analysis” beginning on page 28, which describes in more detail how our executive compensation policies and procedures operate and are designed to achieve our compensation objectives, as well as the Summary Compensation Table and related compensation tables and narrative, which provide detailed information on the compensation of our NEOs.

In accordance with Section 14A of the Exchange Act, and as a matter of good corporate governance, we are asking stockholders to approve the following advisory resolution at the Annual Meeting:

RESOLVED, that the stockholders of NuScale Power Corporation (the “Company”) approve, on an advisory basis, the compensation of the Company’s named executive officers as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission in the Compensation Discussion and Analysis, the Summary Compensation Table and the related compensation tables and narrative in the Proxy Statement for the Company’s 2026 annual meeting of stockholders.

This advisory resolution, commonly referred to as a “say on pay” resolution, is non-binding on the Board. Although non-binding, the Board and the Compensation Committee will review and consider the voting results when evaluating our executive compensation program. At our 2025 annual meeting of stockholders, a majority of stockholders voted to have a “say on pay” vote each year. As a result, we will conduct an advisory vote on executive compensation annually at least until the next stockholder advisory vote on the frequency of such votes. It is expected that the next such “say on pay” vote will occur at the 2027 annual meeting of stockholders.

Vote Required. The affirmative vote of at least a majority of the voting power of the shares of common stock present in person or represented by proxy and entitled to vote on the subject matter, is required to approve the advisory resolution to approve executive compensation. The Board recommends a vote “FOR” the Advisory Resolution to Approve Executive Compensation.

PROPOSAL 3: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


PROPOSAL 3: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of our Board has engaged Ernst & Young LLP (“EY”) as our independent registered public accounting firm for the fiscal year ending December 31, 2026. We are asking our stockholders to ratify the selection of EY as our independent registered public accounting firm. Although ratification is not required by our Bylaws or otherwise, we are submitting the selection of EY 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 EY 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.

Vote Required. The affirmative vote of at least a majority of the voting power of the shares of common stock present in person or represented by proxy and entitled to vote on the subject matter, is required to approve the ratification of the appointment of EY as our independent registered accounting firm.

The Board recommends a vote “FOR” the ratification of the appointment of EY as our independent registered public accounting firm for the fiscal year ending December 31, 2026.

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 2025, with the following exceptions: On behalf of Jose Reyes, NuScale filed one late Form 4 regarding two reportable transactions that occurred on July 1, 2025.

IMPORTANT INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

Why am I receiving these materials?

The Board sent you the Notice of Internet Availability of Proxy Materials (the “Notice”) and 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 2026 Annual Meeting of Stockholders (the "Annual Meeting"), or at any adjournment or postponement of the Annual Meeting. The Annual Meeting will occur on May 29, 2026, at 1:30 p.m. Pacific Time at www.virtualshareholdermeeting.com/SMR2026.

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 the Notice, this proxy statement and the form of proxy card for the Annual Meeting and our Annual Report to Stockholders, which includes our 2025 Annual Report on Form 10-K. We are first making these materials available to you on the Internet on or about April 15, 2026.

What is the purpose of the Annual Meeting?

For stockholders to vote on the following proposals:

1.Elect nine directors 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;

2.Hold a non-binding advisory vote to approve executive compensation;

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 67

3.Ratify the appointment of Ernst & Young LLP (“EY”)as our independent registered public accounting firm for the fiscal year ending December 31, 2026; and

4.Transact any other business as may properly come before the meeting or any adjournment or postponement thereof.

How does the Board of Directors recommend I vote on these proposals?

The Board recommends that you vote:

•"FOR" the election of nine directors: Alan L. Boeckmann, Bum-Jin Chung, Shinji Fujino, Stuart Harshaw, John L. Hopkins, Dale Klein, Kent Kresa, Diana Walters, and Kimberly O. Warnica;

•“FOR” the approval of a non-binding advisory vote to approve executive compensation; and

•"FOR" the ratification of the appointment of EY as our independent registered public accounting firm for the fiscal year ending December 31, 2026.

Who is entitled to vote at the Annual Meeting?

Holders of our Class A common stock and holders of our Class B common stock as of the close of business on March 30, 2026, the record date, may vote at the Annual Meeting. As of the record date, there were 323,734,120 shares of Class A common stock and 19,375,371 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 per share. 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 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:

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 68

•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.

Internet and telephone voting will be available 24 hours a day and will close at 11:59 p.m. Eastern Time on Thursday May 28, 2026.

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 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.

•During the Annual Meeting. If you obtain a legal proxy from your broker, bank or other nominee, you may vote while participating in the Annual Meeting. Instructions on how to vote while participating in the Annual Meeting live via the Internet are posted at www.virtualshareholdermeeting.com/SMR2026.

If you received more than one Notice 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

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 69

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, on the Internet or participating in the Annual Meeting live via the Internet and voting your shares electronically at the Annual Meeting.

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?

We will be hosting the Annual Meeting live via the Internet. You will not be able to attend the Annual Meeting in person. Any stockholder can listen to and participate in the Annual Meeting live via the Internet at www.virtualshareholdermeeting.com/SMR2026. Our virtual Annual Meeting allows stockholders to submit questions and comments before the Annual Meeting. The Annual Meeting webcast will begin promptly at 1:30 p.m. Pacific Time. We encourage you to access the Annual Meeting webcast prior to the start time. Online check-in will begin, and stockholders may begin submitting written questions, at 1:00 p.m., Pacific Time, and you should allow ample time for the check-in procedures.

Can I submit questions in connection with the Annual Meeting?

Yes. Stockholders are encouraged to submit questions in advance of the Annual Meeting by visiting www.proxyvote.com before 11:59 p.m. Eastern Time on Thursday, May 28, 2026 and entering their 16-digit “Control Number.” During the Annual Meeting, we will answer as many stockholder-submitted questions related to the business of the Annual Meeting as time permits.

What constitutes a quorum at the Annual Meeting?

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

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 70

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

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 any of the proposals at the Annual Meeting. 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 or the “say on pay” proposal. Therefore, for your voice to be heard, it is important that you vote.

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 71

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

Effects of Broker Non-Votes

Effects of Abstentions

Election of Directors

the number of votes cast for the nominee’s election exceeds the number of votes cast against

None

affirmative vote of at least a majority of the voting power of the shares of common stock present in person or represented by proxy and entitled to vote on the subject matter,

N/A

Same as vote “against”

Who pays for the cost of this proxy solicitation?

We pay all the costs of preparing, mailing and soliciting the proxies. We 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 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 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

NUSCALE POWER CORPORATION | 2026 PROXY STATEMENT – Page 72

stockholders. The Notice 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. 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 2025 Annual Report, which includes our Form 10-K, and other financial information, on our website at www.nuscalepower.com under the caption "Investors."
