Dear Stockholders,

Today, about 1,400 people work at G1_Dallas manufacturing American energy. These aren’t assembly-line jobs from the 1950s. We’re talking high-tech, high-skill work in robotics, precision engineering, materials science, and quality control. Jobs that pay well. Jobs that need problem solvers. Jobs that build careers.

This is advanced American manufacturing. Humans and advanced robotics, working together to keep one of the world’s most modern solar manufacturing facilities operating safely, efficiently, and profitably.

At T1, we build energy.

We’re operating a facility that produces thousands of solar modules daily. Tested, sorted, and packaged, we load them onto trucks for delivery to tomorrow’s solar farms. To power America’s energy future.

We believe the need for these modules has never been clearer. After years of stagnation, we are in a generational time of energy demand growth. According to the Department of Energy (DOE), in 2025, electricity demand in the U.S. rose 2.8% to a record 4,430 terawatthours, and the DOE expects that electricity generation will rise again in 2026 and 2027. We believe solar and storage are the only energy assets that can scale over the next few years to meet this rising demand.

The United States added 53 gigawatts of new generating capacity to our grids in 2025, the largest increase in more than two decades. We believe this is not ambitious enough. We believe we need to build faster. To accelerate American reindustrialization. To power hyperscalers and win the AI race. To bring advanced manufacturing back.

Last year, 79% of new electricity generation added to U.S. grids was solar and storage. This year is shaping up to be no different. According to data from the DOE, for the first three months of 2026, that figure rose to 88%.

We’ve come a long way fast. Solar and storage were only 15% of new electricity generation as recently as 2018.

Source: DOE, 2026 year-to-date data through March 31

Solar and storage offer a winning combination of scalable, reliable, and low-cost power. This is not about tax credits. All sources of energy benefit from a combination of tax credits, favorable accounting treatment, and grandfathered exemptions from construction codes. We are convinced that the U.S. has the people, skills, technology, and capital to deliver the entire solar value chain from raw polysilicon to solar farm in a cost-competitive manner to support a lasting energy solution.

We see that winning combination being recognized by the market in the U.S. and globally for two reasons.

Table of Contents

The first is cost. Solar is essentially zero-marginal cost electricity generation for decades. Add in capital costs and it is still a very cost-effective solution, according to Rystad Energy, which also reported that battery costs have also fallen remarkably in recent years. Solar delivers abundant, low-cost electricity; batteries store and shift gigawatts, making the combination both affordable and reliable. According to Rystad Energy, solar PV with battery storage has a levelized cost of energy of $68-133/megawatthour compared to U.S. natural gas of $64-125 and large-scale nuclear power of $177-347.

The second is speed. We believe that solar and storage offer one of the fastest, most scalable routes to electricity generation today and for the foreseeable future.

Technology used to govern energy growth. Today, energy governs AI growth.

For decades, advances in oil and gas production relied on breakthroughs in 3D seismic, hydraulic fracturing, combined cycle turbines, and advances in material science for deepwater drilling. Today, energy gatekeeps growth in technology. Without abundant energy, the contest for AI leadership may be lost.

Our mission is to build advanced, domestic solar manufacturing and supply chains in the United States.

In 2025, our first year as T1 Energy, we optimized operations at G1_Dallas, exceeding nameplate capacity. We manufactured 2.79 gigawatts and generated $755.3 million in net sales. Some may see this as a remarkable accomplishment for a new entrant into solar energy. We see it as a good start.

We are committed to running G1 as safely, profitably, and efficiently as possible, combining a world-class workforce, robotics, and AI to supply abundant energy profitably.

To create a domestic supply of solar cells for our modules, our team began construction of our flagship U.S. solar cell fab, G2_Austin, in December. Construction on the first 2.1 gigawatt phase is progressing according to plan. And I’m happy to report that T1 remains on track to start of cell production in the fourth quarter of 2026. When both phases of G2 are completed, bringing total capacity to a planned 5 gigawatts, we expect to support a workforce of up to 1,800 people.

Operating G1. Building G2. These are the building blocks of a company we intend to turn into a cashflow powerhouse. At T1, we are committed to generate value from these world-class assets.

Last year, we laid the foundation to become a new American solar champion. We expect 2026 to be a bridge year to vertical integration, with the first phase of G2 expected to be fully ramped in 2027.

We believe there is significant commercial desire for an American manufacturer of high efficiency, competitively priced solar modules. Last year, we saw evidence of our thesis. We signed a long-term offtake deal with Treaty Oak Clean Energy for domestic modules with domestic cells — and completed merchant sales to several of the largest utility and developer customers.

Table of Contents

While global module pricing remains competitive, we expect domestic content premiums and our roadmap to drive down costs position us well.

Today, we’re offering what we believe is a new choice to the market. Customers can now purchase advanced solar modules from an American-owned facility in Texas. We offer domestic TOPCon modules that achieve 23% efficiency. Next year, we expect to offer domestic TOPCon modules with domestic TOPCon cells. We believe customers will continue to embrace the combination of high efficiency, low-cost modules that are manufactured in America.

Our guiding focus is investing in American advanced manufacturing to power our nation’s energy independence and bring cutting-edge technology capabilities back to the U.S. Manufacturing our electrons in the U.S. can assist in keeping energy affordable, helping ensure data centers have the scalable energy they need when and where they need it, supporting a U.S. polysilicon industry, and empowering U.S.’s AI leadership.

We believe domestic solar manufacturing means the U.S. can continue to be the number one exporter of oil and natural gas while ensuring ample affordable power here at home. Last year, the U.S. exported more liquefied natural gas than any other country has, ever. Solar energy can free natural gas for export. America’s energy abundance (lots of both natural gas and solar farms) creates opportunities to keep energy and electricity prices low at home while also helping it continue to be a worldclass energy exporter. In the U.S., solar and natural gas are working together to fortress America and keep energy insecurity far from our shores.

Solar is how energy abundance becomes durable and permanent. Manufacturing energy abundance with free sunlight is one way we can unlock the next era of American strength.

Domestic solar energy is energy security and energy security leads to economic prosperity. We are proud to play our role in securing a bright future for the United States. Thank you for coming along on this journey.

Sincerely,

Daniel Barcelo
Chief Executive Officer and Chairman of the Board

INFORMATION ABOUT THE ANNUAL MEETING AND PROXY MATERIALS

General

This proxy statement is furnished to stockholders of T1 Energy Inc., a Delaware corporation (the “Company” or “T1 Energy”), in connection with the solicitation of proxies for use at the Annual Meeting of Stockholders of the Company (the “Annual Meeting”) to be held on Wednesday, June 17, 2026, at 12:00 p.m. Eastern Time, online at www.virtualshareholdermeeting.com/TE2026. This solicitation of proxies is made on behalf of the Company’s board of directors (the “Board”).

On January 29, 2021, FREYR AS, a private limited liability company organized under the laws of Norway (“FREYR Legacy”) and Alussa Energy Acquisition Corp., a Cayman Islands exempted company (“Alussa”), among others, entered into that certain Business Combination Agreement (the “BCA”) to effect a merger between the companies (the “Business Combination”). FREYR Battery, a Luxembourg public limited liability company (société anonyme) (“FREYR Lux”) was formed on January 20, 2021, to complete the Business Combination and to serve as the successor entity to FREYR Legacy, the predecessor entity. The merger was completed in multiple stages, pursuant to the terms of the BCA. On July 8, 2021, FREYR Lux’s ordinary shares and warrants began trading on the New York Stock Exchange (“NYSE”) and on July 9, 2021, FREYR Lux completed the Business Combination and FREYR Legacy and Alussa became wholly owned subsidiaries of FREYR Lux.

In 2023, FREYR Lux announced a process to redomicile from Luxembourg to the United States pursuant to an Agreement and Plan of Merger, dated as of October 13, 2023 (the “Merger Agreement”) and the Common Draft Terms of Cross-Border Merger (projet commun de fusion transfrontalière), (the “Cross-Border Merger Agreement”), by and between FREYR Lux and FREYR Battery, Inc. (“FREYR”). At its Extraordinary General Meeting of Shareholders held on December 15, 2023, the shareholders of FREYR Lux approved by the requisite majority the merger of FREYR Lux with and into FREYR, with FREYR as the surviving entity (the “Merger”). On December 31, 2023, FREYR Lux completed the Merger and redomiciliation pursuant to the terms of the Merger Agreement and Cross-Border Merger Agreement and, as a result of the Merger, FREYR became the successor issuer to FREYR Lux. On February 19, 2025, FREYR Battery, Inc. changed its corporate name to T1 Energy Inc.

For the purposes of this proxy statement, references to the “Company,” “T1,” “T1 Energy,” “we,” “our,” “us” and similar terms mean, as of any time prior to the redomiciliation, FREYR Lux and, as of any time after the redomiciliation, T1 Energy, and where appropriate, their respective wholly owned subsidiaries.

Table of Contents

Quorum

A quorum is required in order to hold and conduct business at the Annual Meeting. The holders of at least a majority of the Common Stock issued and outstanding and entitled to vote at the Annual Meeting as of the Record Date present in person or represented by proxy shall constitute a quorum.

If you submit your proxy, regardless of whether you abstain from voting on one or more matters, your shares will be counted as present at the Annual Meeting for the purpose of determining a quorum. If your shares are held in “street name,” your shares are counted as present for purposes of determining a quorum if your broker submits a proxy covering your shares. Your broker is entitled to submit a proxy covering your shares as to certain “routine” matters, even if you have not instructed your broker on how to vote on those matters. Please see below under “— Broker Non-Votes.”

Deadline for Submitting Your Proxy on the Internet

Internet voting will close at 11:59 p.m., Eastern Time, on June 16, 2026. Stockholders who submit a proxy by internet need not return a proxy card or the voting instruction form forwarded by your broker by mail. YOUR VOTE IS VERY IMPORTANT. Please submit your vote in advance, even if you plan to attend the Annual Meeting.

Voting at the Annual Meeting

If you plan to attend the Annual Meeting, you may vote during the virtual meeting. Even if you intend to attend the Annual Meeting, we encourage you to submit your proxy or voting instructions to vote your shares in advance of the Annual Meeting. Please see the important instructions and requirements below under “— Attendance at the Annual Meeting.”

Changing Your Vote

As a stockholder of record, if you vote by proxy, you may revoke that proxy at any time before it is voted at the Annual Meeting. Stockholders of record may revoke a proxy prior to the Annual Meeting by (i) delivering a written notice of revocation to the attention of the Corporate Secretary, T1 Energy Inc., at our principal executive office at T1 Energy Inc. 1211 E 4th Street., Austin, Texas 78702, (ii) duly submitting a later-dated proxy over the internet, by mail, or (iii) attending the Annual Meeting and voting during the meeting. Attendance at the Annual Meeting will not, by itself, revoke a proxy.

If your shares are held in the name of a broker, you may change your voting instructions by following the instructions of your broker or attending the Annual Meeting and voting during the meeting.

If You Receive More Than One Proxy Card

If you receive more than one proxy card, it means you hold shares that are registered in more than one account. To ensure that all of your shares are voted, sign and return each proxy card or, if you submit a proxy by internet, submit one proxy for each proxy card you receive.

How Your Shares Will Be Voted

Shares represented by proxies that are properly executed and returned, and not revoked, will be voted as specified. YOUR VOTE IS VERY IMPORTANT.

If You Do Not Specify How You Want Your Shares Voted

If you are the record holder of your shares and submit your proxy without specifying how your shares are to be voted, your shares will be voted as follows:

• FOR the election of each of the eight director nominees;

• FOR the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for the year ending December 31, 2026;

• FOR the advisory vote on the compensation of our NEOs; and

Table of Contents

• FOR the amendment to our Certificate of Incorporation to increase the number of authorized shares of Common Stock of the Company from 500,000,000 shares to 1,000,000,000 shares.

In addition, the proxy holders named in the proxy are authorized to vote at their discretion on any other matters that may properly come before the Annual Meeting and at any postponement or adjournment thereof as of the date of this proxy statement. The Board knows of no other items of business that will be presented for consideration at the Annual Meeting other than those described in this proxy statement.

Broker Non-Votes

A “broker non-vote” occurs when a nominee holding shares for a beneficial owner has not received voting instructions from the beneficial owner and does not have discretionary authority to vote the shares. If you hold your shares in street name and do not provide voting instructions to your broker, your shares will be considered to be broker non-votes and will not be voted on any proposal on which your broker does not have discretionary authority to vote. Shares that constitute broker non-votes will be counted as present at the Annual Meeting for the purpose of determining a quorum, but will not be considered entitled to vote on the proposal in question. Brokers generally have discretionary authority to vote on the (i) ratification of the selection of KPMG LLP as our independent registered public accounting firm and (ii) amendment to the Certificate of Incorporation to increase the number of authorized shares of Common Stock of the Company from 500,000,000 to 1,000,000,000 shares. Brokers do not have discretionary authority, however, to vote on director elections or the say-on-pay proposal.

Votes Required

The following table summarizes the voting requirements and the effects of broker non-votes or abstentions on each of the proposals to be voted on at the Annual Meeting:

	Proposals	Required Vote	Effect of Broker Non-Votes	Effect of Abstentions
1.	Election of Directors	Majority of votes cast for each nominee	None	None
2.	Ratification of the Appointment of Independent Registered Public Accounting Firm	Majority of shares of Common Stock present or represented by proxy at the Annual Meeting and entitled to vote on the proposal	Not applicable*	Against

General Information About the Board of Directors

Director Independence

The Board has established director independence standards, which are included in our Corporate Governance Guidelines, available on our website at ir.t1energy.com/governance/governance-documents, that are consistent with applicable NYSE listing standards. The NYSE listing standards generally define an “independent director” as a person who the Board affirmatively determines has no material relationship with the Company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the Company), and require that a majority of a board of directors be independent. The Board has determined that Mr. Kantor, Mr. Manners, Dr. Steingart, Ms. Strine, Mr. Hammond and Mr. Anderson are “independent directors,” as defined in the NYSE listing standards.

In determining the independence of the directors, the Board reviewed and considered all relationships between each director (and any member of his or her immediate family) and the Company in light of these independence criteria. In making its independence determinations with respect to Mr. Kantor, the Board considered Mr. Kantor’s service as a Founder, Portfolio Manager and Managing Member of Encompass Capital Advisors, LLC, which is currently the Company’s largest stockholder.

Leadership Structure of our Board of Directors

Our Corporate Governance Guidelines do not mandate that the roles of Chair and CEO be separated or combined. Our Board exercises its discretion in combining or separating these positions as it deems appropriate in the best interests of the Company. Under our Corporate Governance Guidelines, if the Chair of the Board is not an independent director, the Board may appoint a Lead Independent Director.

We believe that our current board structure is effective in supporting strong board leadership. Currently, Mr. Barcelo serves as CEO and Chairman of the Board. The Board has appointed Mr. Anderson as Lead Independent Director. The Lead Independent Director is responsible for, among other things, coordinating the activities of the independent directors, presiding at executive sessions, serving as liaison between the independent directors and the Chairman, and consulting with the Chairman on Board meeting agendas and information flow. The Lead Independent Director’s full responsibilities are described in the Corporate Governance Guidelines, available on our website at ir.t1energy.com/governance/governance-documents. The Board has determined in its judgment that at this time, the Company benefits from having a combined Chairman and CEO position as well as a Lead Independent Director and with independent leadership at the committee level that is designed to enhance the Board’s effectiveness in risk oversight. Mr. Barcelo’s unique perspective and experience, as highlighted more fully above, are valuable in setting the overall direction and business and product strategy for the Company.

Board of Directors’ Role in Risk Oversight

One of the key functions of the Board is informed oversight of T1 Energy’s risk management process. The Board’s Audit and Risk Committee is responsible for assisting and advising the Board in its oversight of the enterprise risk management of the Company. In addition, the Board is routinely presented with information at its regularly scheduled and special meetings regarding risks facing the Company, and management provides more frequent, informal communications to the Board between regularly scheduled meetings which are designed to give the Board regular updates about T1 Energy’s business. The Board considers this information and provides feedback, makes recommendations, and, as appropriate, authorizes or directs management to address particular exposures to risk.

A description of the standing committees of the Board and their functions, including those related to risk oversight, is provided below.

Director Selection and Criteria

The Nominating and Corporate Governance Committee, pursuant to its charter, is responsible for identifying and screening candidates for Board membership and recommending candidates to the entire Board for Board membership.

As set forth in the Company’s Corporate Governance Guidelines, in evaluating director candidates, the Nominating and Corporate Governance Committee will consider the current size and composition of the Board, the needs of the Board and its committees, the candidates’ qualifications, background and experience and other factors

Table of Contents

that the Nominating and Corporate Governance Committee considers appropriate. While the Board has not established specific minimum qualifications for Board members, the Board believes that the assessment of director qualifications may include numerous factors, such as character, professional ethics and integrity, judgment, business acumen, proven achievement and competence in one’s field, the ability to exercise sound business judgment, tenure on the Board and skills that are complementary to the Board, an understanding of the Company’s business, an understanding of the responsibilities that are required of a member of the Board, other time commitments, a wide range of professional backgrounds, education, and viewpoints, as well as other individual qualities and attributes that contribute to the total mix of viewpoints and experience represented on the Board.

The Nominating and Corporate Governance Committee considers recommendations and nominations for candidates to the Board from stockholders, so long as such recommendations and nominations comply with the Company’s Certificate of Incorporation, Third Amended and Restated Bylaws (the “Bylaws”), all applicable Company policies, as well as applicable laws, rules and regulations. Stockholders may recommend director nominees for consideration by the Nominating and Corporate Governance Committee by writing to the Secretary.

Committees of the Board of Directors

The Board has established the following standing committees: Audit and Risk Committee; Compensation Committee; and Nominating and Corporate Governance Committee. From time to time, the Board may establish other committees to facilitate the management of our business. The composition and responsibilities of each of the committees of the Board are described below. Members will serve on these committees until their resignation or until as otherwise determined by the Board. Each of the Board’s standing committees has a written charter, which are available on our website at ir.t1energy.com.

The following table reflects the current membership of the Board’s standing committees:

Name	Audit and Risk Committee	Compensation Committee	Nominating and Corporate Governance Committee
Daniel Barcelo
Peter Matrai
Todd Jason Kantor			🗸
David J. Manners
Daniel Artemus Steingart		Chair
Jessica Wirth Strine	🗸		Chair
W. Richard Anderson	Chair		🗸

Meeting Attendance

Each incumbent director then in office attended at least 75% of the total number of meetings of our Board and any Board Committee on which he or she served. Meetings of the Board and its committees were held in 2025 as follows:

		Number of Meetings
Board of Directors		10
Audit and Risk Committee		6
Compensation Committee		5
Nominating and Corporate Governance Committee		6

T1 Energy’s non-employee directors meet in executive sessions without management present on a periodic basis, but no less than two times a year. The Lead Independent Director presides over these sessions. Independent directors also meet in executive sessions without non-independent directors or management present no less than one time a year. Such meetings are typically held following regularly scheduled Board meetings or at such other times as requested by an independent director.

Table of Contents

Directors are encouraged to attend the Company’s annual meeting of stockholders. All but one of the then-serving directors of the Company attended the Company’s 2025 annual general meeting of stockholders.

Audit and Risk Committee

The Audit and Risk Committee from November 2024 until March 26, 2026, consisted of W. Richard Anderson, Tore Ivar Slettemoen and Jessica Wirth Strine. Since March 26, 2026, this committee consists of Mr. Anderson, who serves as the chair, Mr. Hammond and Ms. Strine. Each of Mr. Anderson, Mr. Hammond and Ms. Strine qualifies as an independent director under the listing standards of the NYSE and the independence requirements of Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Board has determined that Mr. Anderson qualifies as an “audit committee financial expert” as such term is defined in Item 407(d)(5) of Regulation S-K. The Board also previously determined Mr. Slettemoen, who resigned from the Board effective March 26, 2026, qualified as an independent director.

The functions of the Audit and Risk Committee include, among other things, assisting and advising the Board in its oversight of:

• Accounting and financial reporting processes and internal controls of T1 Energy;

• The audit and integrity of T1 Energy’s financial statements;

• T1 Energy’s enterprise risk management and risks and incidents relating to cybersecurity threats;

• T1 Energy’s compliance with applicable laws and regulations (including U.S. federal securities laws and other legal and regulatory requirements);

Audit and Risk Committee Oversight of Material Weakness Remediation

On August 18, 2025, the Company announced it had identified a material weakness in internal control over financial reporting related to our controls over applying technical accounting guidance to nonrecurring events and transactions, including the presentation of amortization for certain customer contracts acquired in the Company’s December 2024 acquisition of Trina Solar US Holding, Inc.

With oversight from the Audit and Risk Committee, the Company remediated this material weakness by expanding our accounting resources at our corporate office with more qualified personnel, supplementing our resources with third-party technical accounting specialists and enhancing the design of process-level review controls over complex technical accounting matters.

In October 2025, the Company hired Tom Mahrer as Director of SEC Reporting, and, in February 2026, appointed Mr. Mahrer as Chief Accounting Officer and Corporate Controller.

On March 31, 2026, the Company disclosed that management identified a material weakness related to the Company’s G1 entity, concluding the Company had ineffective general information technology controls (GITCs) that support the consistent operation of the Company’s Oracle-based information technology system and did not effectively design, implement or operate process-level controls regarding revenue and inventory processes.

Table of Contents

Management has implemented a comprehensive remediation plan to address the material weakness, with direct oversight from the Audit and Risk Committee, which includes:

• Strengthening oversight, including establishing clearer control ownership, formalizing control responsibilities, and increasing the frequency of internal monitoring activities,

• Assigning key accounting processes to sufficiently trained resources with appropriate responsibility and accountability,

• Enhancing GITCs related to our Oracle-based accounting system to support stronger internal control design and operation, standardize workflows, and communicate relevant and reliable information,

• Enhancing data access, accuracy, and transparency, to enable personnel to better understand internal control responsibilities and provide greater visibility into information relied upon for financial reporting,

• Increasing the frequency of monitoring and review procedures to assess the effectiveness of operation of controls and the level of documentation maintained to support their effectiveness, and

• Report regularly to the Audit and Risk Committee on the progress of remediation efforts.

Certain elements of controls have been designed and, in some cases, implemented; however, these controls have not operated for a sufficient period of time to allow management to complete operating effectiveness testing. Management expects these remediation efforts to continue throughout fiscal year 2026.

Compensation Committee

The Compensation Committee from April 2024 until March 26, 2026 consisted of Daniel Artemus Steingart and Tore Ivar Slettemoen. Since March 26, 2026, this committee consists of Dr. Steingart, who serves as the chair, and Mr. Hammond. Each of Dr. Steingart and Mr. Hammond qualifies as an independent director under the listing standards of the NYSE and as a “non-employee director” within the meaning of Rule 16b-3 under the Exchange Act.

The functions of the Compensation Committee include, among other things:

• Overseeing T1 Energy’s compensation policies, plans, benefits, programs and overall compensation philosophy;

DIRECTOR COMPENSATION

Currently, Mr. Barcelo, our Chairman and CEO, is the only Board member who is also a T1 employee. All compensation Mr. Barcelo received from us in 2025 is included in the Summary Compensation Table on page 26 of this Proxy.

The Board has the sole authority to approve the compensation structure for all non-employee directors. The Compensation Committee provides recommendations to the Board on the structure of our non-employee director compensation program. Director compensation is reviewed at least annually and is determined for each one-year Board term, commencing at the Annual Meeting and ending at the following Annual Meeting.

The Board seeks to set non-employee director compensation at an adequate level to compensate non-employee directors for their time and effort expended in satisfying their obligations without jeopardizing their independence. Each year, the Board considers the type and amount of compensation provided to our non-employee directors, using analyses and recommendations from the Compensation Committee’s independent compensation consultant, Kavea Consulting, LLC (“Kavea”), and comparative data from relevant data sources. The Board also takes into account the responsibilities of each committee, the time commitments required for each committee to comply with increasing regulatory requirements and other committee responsibilities, the need to attract and retain quality director candidates, our financial performance, and general market conditions.

Highlights of our Non-Employee Director Compensation Program

• No fees for Board Meeting Attendance: No fees are paid for Board or committee meeting attendance.

• Emphasis on Equity: There is an emphasis on equity in the overall compensation mix to further align interests with stockholders, with annual equity awards vesting on the first anniversary of the grant date.

• Recognition of Special Roles: Special roles (such as committee chairs) are fairly recognized for their additional time commitments, but no fees are paid for committee membership generally.

• Limited Perquisites: Other benefits are limited (e.g., matching charitable contributions).

Director Compensation for 2025 Compensation Period

In 2025, the Compensation Committee considered the compensation of the non-employee directors, seeking the input of our independent compensation consultant, Kavea, and provided a report on director compensation to the Board for its use in setting director pay for the 2025 compensation period. Overall, the Board and the Compensation Committee believe that Kavea’s report showed that our non-employee director compensation program is aligned with market trends. Based on this report and the considerations described above, the Board determined that no changes to the non-employee director compensation program were necessary.

Compensation for non-employee directors for the 2024 and 2025 compensation periods was as follows:

	Assignment	Compensation for 2024 ($)	Compensation for 2025 ($)
Annual cash retainer	Member	100,000	No change
Annual fee for the Audit and Risk Committee	Chair	35,000	No change
Annual fee for the Audit and Risk Committee	Member	20,000	No change
Annual fee for the Compensation Committee	Chair	25,000	No change
Annual fee for the Compensation Committee	Member	10,000	No change
Annual fee for the Nominating & Corporate Governance Committee	Chair	25,000	No change
	Member	10,000	No change
Annual equity award (restricted stock or restricted stock units)		• 50,000 restricted stock units (“RSUs”) for Directors, • 200,000 RSUs for Chairman	No change

Annual equity awards were granted in 2025 pursuant to the T1 Energy Inc. 2021 Equity Incentive Plan, amended and restated by the Board as of April 22, 2024, and approved by the Company’s stockholders on June 13, 2024 (the “ Equity Plan”).
