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.

![](tbarchart_001.jpg)

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**](#TOC001)

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.

![](tbarchart_002.jpg)

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 and we expect in 2027 to generate an annualized run rate of $375 million to $450 million in adjusted EBITDA once the first phase of G2 is fully ramped.

------

[**Table of Contents**](#TOC001)

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.

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.

**________________________________**

#### 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.&nbsp;&nbsp;&nbsp;&nbsp; To approve an amendment to our Amended and Restated Certificate of Incorporation (as amended, the "Certificate of Incorporation") to increase the number of authorized shares of common stock, par value $0.01 per share ("Common Stock"), of the Company from 500,000,000 shares to 1,000,000,000 shares; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.&nbsp;&nbsp;&nbsp;&nbsp; Any other matter that properly comes before the Annual Meeting.

#### Who Can Vote
At the close of business on May 8, 2026 (the "Record Date"), there were 279,271,380<sup>2</sup> shares of our Common Stock outstanding. Each share of our Common Stock outstanding on the Record Date is entitled to one vote on each of the eight director nominees and one vote on each other matter. Your shares of Common Stock may be voted at the Annual Meeting, or any adjournment or postponement thereof, only if your shares are represented by a valid proxy or you are present in person at the Annual Meeting.

#### Voting by Stockholders of Record
If you are a stockholder of record (your shares are registered directly in your name with our transfer agent), you may vote by proxy via the internet or by mail by following the instructions provided on the proxy card. Stockholders of record who attend the Annual Meeting may vote during the Annual Meeting by visiting *www.virtualshareholdermeeting.com/TE2026*, entering the applicable control number, and following the instructions on the Annual Meeting website.

#### Voting by Beneficial Owners (Holders in "Street Name")
If your shares are held in a stock brokerage account or by a bank, trust or other nominee (each, a "broker"), then you are not considered the stockholder of record with respect to those shares. However, you are still considered to be the beneficial owner of those shares, and your shares are said to be held in "street name." Street name holders may vote by proxy by following the instructions provided in the voting instruction form or other materials provided to you by the broker that holds your shares. If you do not provide specific voting instructions to the nominee that holds your shares, such nominee will have the authority to vote your shares only with respect to 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 (such proposals are considered "routine" matters under New York Stock Exchange ("NYSE") rules), and your shares will not be voted and will be considered "broker non-votes" with respect to the other proposals (such proposals are considered "non-routine" matters under NYSE rules). To vote during the Annual Meeting, visit *www.virtualshareholdermeeting.com/TE2026*, enter the applicable control number and follow the instructions on the Annual Meeting website. You may contact the bank, broker or other institution where you hold your account if you have questions about obtaining your control number.

____________

2&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The share information set forth herein is presented as of May 6, 2026, the most recent practicable date prior to the filing of this Preliminary Proxy Statement. The final share information will be provided as of the May 8, 2026 record date in the Definitive Proxy Statement.

[**Table of Contents**](#TOC001)

#### 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 4<sup>th</sup> 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:

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

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

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

[**Table of Contents**](#TOC001)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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 <br>Non-Votes** | **Effect of <br>Abstentions** |
| 1. | Election of Directors | Majority of votes cast for each nominee |  |  |
| 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 |
| 3. | Advisory Vote on the Compensation of Our NEOs | Majority of shares of Common Stock present or represented by proxy at the Annual Meeting and entitled to vote on the proposal |  | Against |
| 4. | Amendment to the Certificate of Incorporation to increase the number of authorized shares of Common Stock of the Company | Majority of the outstanding shares of Common Stock | Not applicable\* | Against |

---

____________

\*&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Proposals 2 and 4 are considered "routine" matters and therefore brokers generally may vote on these matters in their discretion on behalf of beneficial owners who have not furnished voting instructions.

**THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE IN FAVOR OF THE ABOVE NOMINEES FOR ELECTION AS DIRECTORS.**

#### 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**](#TOC001)

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:

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.

#### 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 25 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
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**No fees for Board Meeting Attendance:&nbsp;&nbsp;&nbsp;&nbsp;**No fees are paid for Board or committee meeting attendance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**Emphasis on Equity:&nbsp;&nbsp;&nbsp;&nbsp;**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.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**Limited Perquisites:&nbsp;&nbsp;&nbsp;&nbsp;**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 <br>($)** | **Compensation <br>for 2025 <br>($)** |

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").

[**Table of Contents**](#TOC001)

#### PROPOSAL 2 — RATIFICATION OF THE APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Audit and Risk Committee is responsible for the appointment, compensation, retention and oversight of the Company's independent auditors. In connection with this responsibility, the Audit and Risk Committee evaluates and monitors the auditors' qualifications, performance and independence. This responsibility includes a review and evaluation of the independent auditors. The Audit and Risk Committee approves all audit engagement fees and terms associated with the retention of the independent auditors. The Audit and Risk Committee charter requires the Audit and Risk Committee to consider whether the independent audit firm should be rotated. In addition to evaluating rotation of the independent auditors, the Audit and Risk Committee oversees the selection of the lead audit partner.

As a matter of good corporate governance, the Board is requesting our stockholders to ratify the Audit and Risk Committee's selection of KPMG LLP as our independent registered public accounting firm for the year ending December 31, 2026. Our Board has directed that this appointment be submitted to our stockholders for ratification at the Annual Meeting. We value the opinions of our stockholders and believe that stockholder ratification of our appointment is good corporate governance practice.

On September 5, 2025, the Audit and Risk Committee (i) approved the dismissal of PricewaterhouseCoopers AS ("PwC Norway") as the Company's independent registered public accounting firm and (ii) appointed KPMG LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2025, including performing reviews of the interim periods ending September 30, 2025. PwC Norway had served as the Company's auditor since 2020.

The audit reports of PwC Norway on the Company's consolidated financial statements as of and for the fiscal years ended December 31, 2024 and 2023 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles. During the fiscal years ended December 31, 2024 and 2023, and the subsequent interim period through September 5, 2025, there were no: (i) "disagreements," as that term is defined in Item 304(a)(1)(iv) of Regulation S-K under the Securities Act of 1933 ("Regulation S-K") with PwC Norway on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of PwC Norway, would have caused PwC Norway to make reference to the subject matter of such disagreements in connection with its audit reports on the Company's consolidated financial statements as of and for the fiscal years ended December 31, 2024 and 2023, or (ii) reportable events within the meaning of Item 304(a)(1)(v) of Regulation S-K, other than, as previously disclosed in an amendment to the Company's Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2025, a material weakness in internal control over financial reporting related to its controls over applying technical accounting guidance to nonrecurring events and transactions, including the design and maintenance of effective controls to evaluate the appropriate presentation of the amortization of intangible assets related to certain customer contracts within our statements of operations and comprehensive income (loss).

The Audit and Risk Committee and the Board believe that the retention of KPMG LLP as our independent auditors is in the best interests of the Company.

If the stockholders do not ratify the selection, the Audit and Risk Committee will reconsider its selection and will also consider this fact when it appoints the Company's independent auditors for the fiscal year ending December 31, 2027. Even if the selection is ratified, the Audit and Risk Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if the Audit and Risk Committee determines that such a change would be in the best interests of the Company and its stockholders.

Representatives from KPMG LLP are expected to be present at the Annual Meeting and will have an opportunity to make a statement at the Annual Meeting if they desire to do so and are expected to be available to respond to appropriate questions at the Annual Meeting.

**THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE IN FAVOR OF THE RATIFICATION OF THE APPOINTMENT OF KPMG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE YEAR ENDING DECEMBER 31, 2026.**

#### Fees Paid to Independent Registered Public Accounting Firms
The Company's principal accountant for the year ended December 31, 2025 was KPMG LLP. The Company's principal accountant for the year ended December 31, 2024 was PwC Norway, which also performed reviews of the interim periods ending March 31, 2025 and June 30, 2025, before being dismissed on September 5, 2025. See "Ratification of the Appointment of Independent Registered Public Accounting Firm" above for additional information regarding the change in the Company's independent registered public accounting firm.

The following tables set forth the fees and expenses billed to us by KPMG LLP for 2025 and PricewaterhouseCoopers AS Norway for 2024:

(2)&nbsp;&nbsp;&nbsp;&nbsp; Audit-related fees consist of fees billed for assurance and related services that are reasonably related to the performance of the audit or review of our financial statements and are not reported under "Audit Fees."

(4)&nbsp;&nbsp;&nbsp;&nbsp; Other fees consist of fees billed for advisory services that are not included in the above categories.

#### Approval of Audit and Permissible Non-Audit Services
Our Audit and Risk Committee charter requires the Audit and Risk Committee to review and approve all audit services and all permissible non-audit services to be performed for us by our independent registered public accounting firm. The Audit and Risk Committee will not approve any services that are not permitted by SEC rules. The Audit and Risk Committee pre-approved all audit, audit related, tax, and non-audit related services to be performed for us by our independent registered public accounting firm.

[**Table of Contents**](#TOC001)

#### AUDIT AND RISK COMMITTEE REPORT
The Audit and Risk Committee reviewed and discussed the consolidated financial statements for the year ended December 31, 2025, with our management and with our independent registered public accounting firm, KPMG LLP. In addition, the Audit and Risk Committee discussed with KPMG LLP the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (the "PCAOB") and the SEC. The Audit and Risk Committee also discussed with KPMG LLP the written disclosures and the independence letter from KPMG LLP required by the applicable requirements of the PCAOB.

Based on the Audit and Risk Committee's review of the consolidated financial statements and the review and discussions described in the preceding paragraph, the Audit and Risk Committee recommended to the Board that the consolidated financial statements be included in 2025 Form 10-K.

#### EXECUTIVE COMPENSATION

#### Compensation Overview
The Compensation Committee oversees our compensation programs for executive officers and all other employees. This section discusses the compensation awarded to, earned by, or paid to T1 Energy's CEO and two other most highly compensated executive officers who were serving as executive officers as of December 31, 2025. These three named executive officers, known as the "NEOs," are:

---

| | | |
|:---|:---|:---|
|  **Daniel Barcelo** | **Joseph Evan Calio** | **Einar GS Kilde<sup>(1)</sup>** |
|  Chairman of the Board and <br>Chief Executive Officer <br>(CEO) | Chief Financial Officer <br>(CFO) | Chief Development Officer |

---

____________

(1)&nbsp;&nbsp;&nbsp;&nbsp; Mr. Kilde retired from the Company effective April 22, 2026. For further discussion, see "Separation Agreement" below.

#### Elements of Compensation

#### Base Salary
The Compensation Committee annually reviews executive officer base salary levels, typically at the beginning of the year, with a goal of providing competitive, fixed cash compensation. The Compensation Committee generally seeks to maintain executive base salaries near the median level of salaries for comparable positions within the industry. The 2025 base salaries for our NEOs were as follows:

---

| | | | |
|:---|:---|:---|:---|
|  **Named Executive Officer** | **2024 <br>Base Salary** | **Increase %** | **2025 <br>Base Salary** |
|  **Daniel Barcelo** | $800000 | 0% | 800000 |
|  **Joseph Evan Calio** | $600000 | 0% | 600000 |
|  **Einar GS Kilde** | NOK 4,454,656 | 21% | NOK 5,500,000 |

---

#### 2025 Annual Incentive Awards
For 2025, our NEOs were eligible to earn short-term incentive plan ("STIP") awards under T1's Annual Incentive Plan (hereafter the "2025 STIP"). The STIP provides participants with an opportunity to earn a cash incentive based on an equally weighted combination of quantitative Company and individual performance goals during the year. In addition to the defined goals, any payout is contingent upon an overarching assessment of Company performance by the Compensation Committee at year-end (a "threshold requirement"). To ensure that outcomes appropriately reflect T1 Energy's aggregate performance that might not otherwise be reflected in the Company performance goals, the Compensation Committee has the ability to reduce the STIP outcome, including reducing it to zero, based on its assessment of whether the outcome reflects T1 Energy's broader full-year performance.

The Compensation Committee may adjust the ultimate STIP award payment a NEO would receive with respect to the Company performance measures, up or down, based on the Compensation Committee's assessment of the NEO's performance for the year. To that end, the Compensation Committee considers various criteria, including each NEO's impact during the year and overall value to T1, specifically considering each NEO's leadership skills, impact on strategic initiatives, performance in their primary area of responsibility, role and trajectory in succession planning and development, and other intangible qualities that contribute to our success.

#### Long-Term Equity-Based Incentive Awards
Each year, we grant our NEOs long-term equity-based incentive awards. The Compensation Committee determines the amount of these awards, as well as the mix of time-based awards. Currently, our long-term equity-based incentive awards are in the form of stock options and RSUs. When considering the total long-term equity-based incentive award amount granted to each NEO, the Compensation Committee generally reviews estimated targets for compensation, the relative value of each compensation element, the expense of such awards, and the impact on dilution. Information on long-term incentive plan awards granted to our NEOs in 2025 can be found in the Summary Compensation Table below.

[**Table of Contents**](#TOC001)

#### Retirement, Health and Welfare Benefits
T1 Energy provides benefits to its NEOs on the same basis as provided to all of its employees in the same jurisdiction, including a defined contribution retirement program for NEOs based outside of the U.S. All U.S.-based T1 Energy employees are eligible to participate in and receive annual Company-matching contribution to our 401(k) Plan, equal to 100% of the first 3% of employee contributions, 50% for the next 2% of employee contributions up to a total match of 4% of salary which is intended to provide financial security upon retirement.

#### Independent Compensation Consultant
Under its charter, the Compensation Committee has the authority, in its sole discretion, to retain or obtain the advice of a compensation consultant. After an extensive review of proposals from several leading compensation consultants, the Committee determined to retain Kavea as its independent compensation consultant effective beginning in 2025. The Committee did not engage any other consultants to provide executive compensation consulting services on its behalf during the 2025 fiscal year.

Kavea assists the Compensation Committee in developing a competitive total compensation program that is consistent with our philosophy of goal-oriented pay for performance and that allows us to attract, retain and motivate talented executives. For 2025, Kavea's services included providing an annual analysis of the compensation of our officers and directors, and their counterparts at comparator companies. The analysis compares each element of compensation and total direct compensation awarded by T1 and by our peers to our respective executive officers and directors. Kavea also provides assistance in the ongoing support with respect to regulatory and other considerations that affect compensation programs as requested by the Compensation Committee.

Kavea reports exclusively to the Compensation Committee. The Compensation Committee reviewed Kavea's independence and determined that there were no conflicts of interest as a result of this engagement.

#### Role of Stockholders
T1 Energy is committed to meaningful investor outreach. We embrace an open and accessible relations program for current and prospective investors, that provides a forum for dialogue. During the year, no questions or feedback were received in relation to executive compensation practices. At our upcoming Annual Meeting, the Board is recommending a vote in favor of an annual say-on-pay vote. By conducting such a vote annually, it provides the Compensation Committee with an opportunity to review insight into views on executive compensation practices across our stockholder base. The Compensation Committee will consider the results of the say-on-pay vote, along with feedback shared during engagement and broader stakeholder perspectives, such as guidance issued by proxy advisors, in discharging its duties.

#### Clawback Policy
The Board has approved and adopted a compensation recoupment policy to comply with NYSE requirements. The policy applies to current and former executive officers and covers incentive-based compensation. In the event of a financial restatement, any compensation that is determined to have been erroneously awarded during the three-year lookback period is subject to repayment. A copy of the Clawback Policy can be found as an exhibit to the 2025 Form 10-K. During the Company's prior fiscal year, no action was required under this policy.

In addition, certain employment contracts and employment agreements contain additional recoupment provisions.

#### Insider Trading Policy
The Company maintains insider trading policies and procedures governing the purchase, sale and other dispositions of our securities by our directors, officers, employees and certain other individuals associated with us that we believe are reasonably designed to promote compliance with insider trading laws, rules and regulations and listing standards applicable to us. The policy also applies to material non-public information of the Company, which includes major events involving the Company's securities, such as the adoption of share repurchase programs, option repricing, share splits, changes in dividend policies, public or private securities offerings, modification to the rights of security holders or notice of delisting.

[**Table of Contents**](#TOC001)

#### Anti-Hedging and Anti-Pledging Policies
The Company maintains an Insider Trading Policy that is applicable to all directors and employees, including our NEOs. Among other things, the policy prohibits any director or employee of the Company from (i) engaging in short sales of the Company's securities (ii) trading in publicly-traded options, such as puts and calls, and other derivative securities with respect to the Company's securities (other than stock options, RSUs and other compensatory awards issued by the Company) (iii) engaging (directly or indirectly) in hedging transactions, or otherwise engage in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of Company securities, (iv) pledging the Company's securities as collateral for any loan or as part of any other pledging transaction, unless approved by the Compliance Officer in writing, (v) holding Common Stock in margin accounts, or (vi) placing standing or limit orders on Company securities, unless executed as part of an approved Rule 10b5-1 Plan.

#### Compensation Committee Interlocks and Insider Participation
None of the members of our Compensation Committee has at any time been one of our executive officers or employees. None of our executive officers currently serves, or has served during the last completed fiscal year, on the Compensation Committee or board of directors of any other entity that has one or more executive officers serving as a member of our board of directors or Compensation Committee.

#### Policies and Practices Related to the Grant of Certain Equity Awards
The Compensation Committee takes into account the timing of our disclosure of material nonpublic information when awarding stock options. Specifically, we generally do not grant stock options (i) during trading blackout periods established under our Insider Trading Policy, or (ii) at any time during the four business days prior to or the one business day following the filing of our periodic reports or the filing or furnishing of a Form 8-K that discloses material nonpublic information. These restrictions do not apply to RSUs or other types of equity awards that do not include an exercise price related to the market price of our Common Stock on the date of grant. In compliance with Item 402(x) of Regulation S-K, the following table sets forth certain information regarding the options granted to one of our named executive officers in 2025:

#### Pay Versus Performance
Pursuant to Section 953(a) of the Dodd-Frank Act and Item 402(v) of SEC Regulation S-K, we are providing the following information about the relationship between executive "compensation actually paid" (or "CAP") to the Company's principal executive officer ("PEO") and non-PEO NEOs for 2025, 2024 and 2023 and certain aspects of the financial performance of the Company. The Compensation Committee does not utilize CAP as the basis for making compensation decisions. We do not currently use any other financial performance measure to link CAP to the CEO and our other NEOs to the Company's performance.

(2)&nbsp;&nbsp;&nbsp;&nbsp; SEC rules require certain adjustments be made to the Summary Compensation Table ("SCT") totals to determine CAP as reported in the Pay versus Performance Table. CAP does not necessarily represent cash and/or equity value transferred to the applicable NEO as realized income, but rather is a value calculated under applicable SEC rules. In general, CAP is calculated as Summary Compensation Table total compensation adjusted to include the fair market value of equity awards

#### Employment Agreements with T1 NEOs
Below are descriptions of employment agreements with our current NEOs. These agreements set forth the NEO's initial compensation, eligibility for employee benefits and potential to receive severance payments and benefits upon a qualifying termination of employment.

*Employment Agreement with Mr. Barcelo*

We entered into an employment agreement with Mr. Barcelo setting forth the terms and conditions of his employment as our Chief Executive Officer on April 25, 2025. Mr. Barcelo will receive an annual base salary of $800,000. He is eligible to receive an annual cash incentive bonus opportunity in an amount up to 100% of his base salary pursuant to T1 Energy's STIP and receive awards under the Equity Plan. For the 2025 fiscal year, Mr. Barcelo's annual equity awards will consist of two separate awards: (i) RSUs covering a number of shares of Common Stock of the Company with a fair market value at the time of grant equal to 150% of his base salary, which will vest in substantially equal tranches on each of the first three anniversaries of the grant date, subject to his continued active employment with the Company on the applicable vesting date and (ii) RSUs covering a number of shares of Common Stock of the Company with a fair market value at the time of grant equal to 150% of his base salary, which will fully vest on the first anniversary of the grant date, subject to his continued active employment with the Company on the vesting date.

If Mr. Barcelo's employment is terminated by the Company without cause or if he resigns for good reason, he will be eligible to receive (i) continued payment of one year of his then-current base salary (which will increase to 18 months of his then-current base salary if such termination occurs within 12 months following a change in control), (ii) any earned but unpaid annual cash bonus payable in respect of any previously completed fiscal year, (iii) a pro-rated annual cash bonus for the year in which his termination of employment occurs, (iv) up to six months of reimbursed COBRA premiums and (v) unless Mr. Barcelo transitions to a Board only role following such termination of employment, full accelerated vesting of all unvested equity awards (with any performance-based equity awards being deemed achieved at target performance levels). In the event of a change in control, any equity award granted to Mr. Barcelo between April 25, 2025 and April 25, 2026 will become fully vested upon such change in control. In addition, if Mr. Barcelo no longer serves as our CEO (except in connection with a termination of his employment for cause, his resignation without good reason or as a result of his death or disability), any unvested equity awards will become fully vested at the time he ceases to serve as our CEO.

[**Table of Contents**](#TOC001)

*Employment Agreement with Mr. Calio*

We entered into an employment agreement with Mr. Calio to serve as our Chief Financial Officer in June 2024. Mr. Calio's annual salary as of December 31, 2024 was $600,000 and he is eligible to participate in the group bonus scheme with a target bonus potential of 100% of his base salary. Mr. Calio received a one-time award of RSUs with respect to a number of shares of Common Stock of the Company (the "Sign-On RSUs"). The number of Sign-On RSUs awarded equaled a nominal value of $3.0 million divided by the volume weighted average price of the Common Stock of the Company for a 15-trading day period ending on the first date of employment. In the first three years of service, Mr. Calio is entitled to receive a grant of 300,000 of non-qualified stock options and a grant of RSUs with a fair market value of $600,000. Upon a termination of Mr. Calio's employment without cause or his resignation for good reason ("Qualifying Termination"), Mr. Calio would be entitled to receive a cash severance payment equal to 12 months of his base salary, payable in substantially equal installments during the 12 month period immediately following the date of his termination, and reimbursement of COBRA premiums for a period of six months following the date of his termination. In the event of a Qualifying Termination within 12 months following a change in control, Mr. Calio's outstanding equity awards would become fully vested.

*Employment Agreement with Einar GS Kilde*

We entered into an employment agreement with Mr. Kilde in May 2021. Mr. Kilde's annual salary as of December 31, 2025 was NOK 4.05 million and he is eligible to participate in the group bonus scheme with a target bonus potential of 50% of his base salary. Mr. Kilde is eligible to receive equity awards under the Equity Plan. In connection with Mr. Kilde's retirement as Chief Development Officer, FREYR Battery Norway AS (a wholly-owned subsidiary of the Company) and Mr. Kilde entered into a separation agreement (the "Separation Agreement") on April 22, 2026 (the "Effective Date"). Pursuant to the Separation Agreement, Mr. Kilde will be entitled to receive a severance payment of NOK 5.5 million to be paid in twelve equal installments following the Effective Date. Mr. Kilde's outstanding options and RSUs will remain outstanding and eligible to vest in accordance with the terms and conditions of the Equity Plan and the applicable award agreements under which they were granted and the terms of Mr. Kilde's options have been extended such that they may be exercised beyond the default period of three months post-employment under the Equity Plan.

#### Restrictive Covenants
Each NEO employment agreement contains post-termination restrictive covenants, including with respect to non-competition, non-solicitation and confidentiality.

[**Table of Contents**](#TOC001)

#### PROPOSAL 3 — ADVISORY VOTE ON THE COMPENSATION OF OUR NEOs
In accordance with Section 14A of the Exchange Act and the related SEC rules, we are asking our stockholders to vote at the Annual Meeting to approve, on an advisory basis, the compensation of our NEOs as disclosed in this proxy statement.

Our executive compensation program is a vital tool to attract and retain top talent and ensure that our corporate goals are being met successfully and is designed to provide market competitive compensation and benefit levels that will attract, retain, motivate and reward a talented team of executive officers; integrate pay with the Company's annual and long-term performance goals; encourage behaviors that are in the best interests of our customers, stockholders and the goals of the organization, and reinforce our culture.

Our executive compensation program is structured within a strong framework of compensation governance with a bias toward compensation that is dependent on long-term company performance and balanced to mitigate risks appropriately.

We are asking our stockholders to indicate their support for our NEO compensation as described in this proxy statement. Accordingly, we are asking our stockholders to vote on an advisory basis "FOR" the following non-binding resolution:

"RESOLVED, that the compensation of the Company's NEOs, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, is hereby approved."

The vote on this proposal is not intended to address any specific element of compensation; rather, the vote relates to all compensation relating to the Company's NEOs, as described in this proxy statement. The vote is advisory and is not binding on the Company, the Board or the Compensation Committee, and will not be construed as overruling a decision by, or creating or implying any additional fiduciary duty for, the Company, the Board or the Compensation Committee. However, the Board and the Compensation Committee value the opinions expressed by stockholders in their votes on this proposal and will consider the outcome of the vote when making future compensation decisions and policies regarding the Company's executive officers. Unless the Board modifies its determination on the frequency of future say on pay advisory votes, the next say on pay advisory vote will be held at our 2027 Annual Meeting.

#### THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" THE APPROVAL OF THE COMPENSATION OF OUR NEOS.

[**Table of Contents**](#TOC001)

#### PROPOSAL 4 — AMENDMENT OF THE CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK

#### Overview
The Company's Certificate of Incorporation currently authorizes the issuance of 500,000,000 shares of Common Stock and 10,000,000 shares of the Company's preferred stock. On the Record Date, there were 279,271,380<sup>5</sup> shares of Common Stock issued and outstanding and 6,600,000 shares of Preferred Stock issued and outstanding. In addition, as of the Record Date, a total of 165,659,997<sup>6</sup> shares of Common Stock were reserved for issuance pursuant to either the Company's equity compensation plans and outstanding equity awards, upon exercise of outstanding warrants or upon conversion of the outstanding Preferred Stock or the Company's 5.25% convertible senior notes due 2030 and 4.00% convertible senior notes due 2031.

The Board has approved, subject to stockholder approval, an amendment to the Company's Certificate of Incorporation to effect an increase the number of authorized shares of Common Stock from 500,000,000 to 1,000,000,000 (the "Authorized Share Increase"). The Board has not approved an increase in the shares of Preferred Stock. The additional shares of Common Stock authorized by the Authorized Share Increase, if and when issued, would have the same rights and privileges as the shares of Common Stock previously authorized.

This Proposal 4, if approved, would amend Article 4(a) of the Company's Certificate of Incorporation as follows (additions are double underlined and deletions are struck through):

FOURTH:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Authorized Capital Stock</u>. The total number of shares of stock which the Corporation shall have authority to issue is five hundred ten million (510,000,000) <u>one billion ten million (1,010,000,000)</u> shares of capital stock, consisting of (i) five hundred million (500,000,000) <u>one billion (1,000,000,000)</u> shares of common stock, par value $0.01 per share (the "Common Stock"), and (ii) ten million (10,000,000) shares of preferred stock, par value $0.01 per share (the "Preferred Stock"). The number of authorized shares of Common Stock or Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the then outstanding shares of Common Stock, without a vote of the holders of the Preferred Stock, or of any series thereof, unless a vote of any such Preferred Stock holders is required pursuant to the provisions established by the Board of Directors of the Corporation in the resolution or resolutions providing for the issue of such Preferred Stock, and if such holders of such Preferred Stock are so entitled to vote thereon, then, except as may otherwise be set forth in the certificate of incorporation of the Corporation, the only stockholder approval required shall be the affirmative vote of a majority of the voting power of the Common Stock and the Preferred Stock so entitled to vote, voting together as a single class.

The above summary is qualified in its entirety by reference to the full text of the Certificate of Amendment for the Authorized Share Increase to the Certificate of Incorporation, a copy of which is attached hereto as Annex A.

The Board has recommended that the proposed Certificate of Amendment for the Authorized Share Increase be presented to the Company's stockholders for approval.

#### Reasons for Seeking Stockholder Approval
On the Record Date, 279,271,380<sup>7</sup> shares of our Common Stock were outstanding, out of the 500,000,000 authorized in our Certificate of Incorporation. The Authorized Share Increase is independent of any other matters or proposals discussed in this Proxy Statement and the additional shares of Common Stock authorized by such increase can be issued at the discretion of the Board from time to time for any proper corporate purpose, including, without

5&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The share information set forth herein is presented as of May 6, 2026, the most recent practicable date prior to the filing of this Preliminary Proxy Statement. The final share information will be provided as of the May 8, 2026 record date in the Definitive Proxy Statement.

6&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The share reserve information set forth herein is presented as of May 6, 2026, the most recent practicable date prior to the filing of this Preliminary Proxy Statement. The final share reserve information will be provided as of the May 8, 2026 record date in the Definitive Proxy Statement.

The final share information will be provided as of the May 8, 2026 record date in the Definitive Proxy Statement.

limitation, the acquisition of other businesses, the raising of additional capital for use in our business, including in connection with the issuance and exercise of warrants, a split of or dividend on then outstanding shares or in connection with any employee stock plan or program. Except to the extent required by applicable law or regulation, any future issuances of authorized shares of Common Stock may be approved by the Board without further action by the stockholders. The availability of additional shares of Common Stock would be particularly important in the event that the Board needs to undertake any of the foregoing actions on an expedited basis in order to avoid the time and expense of seeking stockholder approval in connection with the contemplated issuance of Common Stock, where such approval might not otherwise be required.

Although the Board will issue Common Stock only when required or when the Board considers such issuance to be in the Company's best interests, the issuance of additional Common Stock may, among other things, have a dilutive effect on the earnings per share (if any) and on the equity and voting rights of our existing stockholders.

Additionally, the presence of such additional authorized but unissued shares of Common Stock could discourage unsolicited business combination transactions which might otherwise be desirable to stockholders. While it may be deemed to have potential anti-takeover effects, the proposed Authorized Share Increase is not prompted by any specific effort or takeover threat currently perceived by management. In addition, we do not have any plans to implement additional measures having anti-takeover effects. The Board believes that the benefits of providing it with the flexibility to issue shares without delay for any proper business purpose, including as an alternative to an unsolicited business combination opposed by the Board, outweigh the possible disadvantages of dilution and discouraging unsolicited business combination proposals and that it is prudent and in the best interests of stockholders to provide the advantage of greater flexibility which will result from the Authorized Share Increase.

#### Procedure for Effecting the Authorized Share Increase
If stockholders approve the Authorized Share Increase, the Company intends to promptly file the Certificate of Amendment with the Secretary of State of the State of Delaware to amend its existing Certificate of Incorporation. The Authorized Share Increase will become effective on the date of filing the Certificate of Amendment. The text of the Certificate of Amendment is set forth in Annex A to this proxy statement. The text of the Certificate of Amendment is subject to modification to include such changes as may be required by the office of the Secretary of State of the State of Delaware and as the Board deems necessary and advisable to effect the Authorized Share Increase. The Board reserves the right, notwithstanding stockholder approval of the Authorized Share Increase and without further action by the stockholders, to elect not to proceed with the Authorized Share Increase if, at any time prior to filing the Certificate of Amendment, the Board determines that it is no longer advisable and in the best interests of the Company and its stockholders to proceed with the Authorized Share Increase.

The description of the Certificate of Amendment set forth above is qualified in its entirety by reference to the text of the Certificate of Amendment, which is attached as Annex A to this Proxy Statement.

Furthermore, upon the closing of the Trina Business Combination, one-third of Mr. Jensen's outstanding performance stock options vested immediately and 50% of the remaining unvested portion of the performance stock options vested on December 23, 2025, the first anniversary of the closing date of the Trina Business Combination. The remaining 50% of the unvested portion will vest on December 23, 2026, the second anniversary of the closing date of the Trina Business Combination.

Lastly, we entered into a consultancy agreement with Mr. Lin on November 6, 2024 (which we refer to as the "Original Lin Consulting Agreement"), which became effective on December 23, 2024.

#### Trina Commercial Agreements
*Module Operational Support Agreement*

Under the Module Operational Support Agreement, TUS will provide various services including advisory, technical support, manufacturing quality and risk management, smart manufacturing systems, equipment operation and maintenance, training, warehouse management and logistics. We handle all other aspects of managing and operating the solar module manufacturing facility, including strategic planning, financial management, manufacturing, quality controls, maintenance, human resources, and managing contracts and vendors.

[**Table of Contents**](#TOC001)

In return for their services, we will pay TUS an annual fee that is 5% of combined adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization) of G1 or the combined adjusted EBITDA of G1 and T1 G2 Austin Solar Cell LLC (f/k/a Trina Solar US Manufacturing Cell 1, LLC) ("G2"), as applicable, for the relevant year. Adjusted EBITDA is calculated after deducting the general and administrative allocation, equivalent to $15 million (the "G&A allocation"), and all costs outlined in the Related Commercial Agreements with Trina Parent. Additionally, we will reimburse TUS and its affiliates for any costs and expenses they incur while providing these services.

This agreement will remain in effect until the later of December 23, 2029, or the date when all obligations under the credit agreement, dated as of July 16, 2024, by and among T1 G1 Dallas Solar Module LLC, as borrower, and HSBC Bank USA, N.A., as administrative and collateral agent (as amended, restated, supplemented or otherwise modified from time to time, the "Credit Agreement") are fully repaid or discharged.

*Sales Agency and Aftermarket Services Agreement*

At Closing, G1 signed a sales agency and aftermarket services agreement with TUS (the "Sales Agency Agreement"), as amended on December 29, 2025, pursuant to which TUS handles the marketing and sales of solar energy modules made by or for G1.

Under this agreement, Trina Parent provides product warranty for the photovoltaic ("PV") solar modules sold that are branded with the Trina trademark (the "Covered Product"). Trina Parent also offers support services to customers in the U.S. who buy the Covered Product. This includes managing a call center for customer complaints, handling returns and resolving warranty claims relating to the Covered Products.

For the marketing and sales services, TUS earns commissions based on the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.&nbsp;&nbsp;&nbsp;&nbsp; For the sales of the first 1.5 GWs of Covered Products: $0.02 per watt if the solar cells are sourced from outside the United States and $0.035 per watt if the solar cells are sourced from within the United States.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.&nbsp;&nbsp;&nbsp;&nbsp; For any additional sales of Covered Products:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.&nbsp;&nbsp;&nbsp;&nbsp; 2% of the sales price;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.&nbsp;&nbsp;&nbsp;&nbsp; An additional 50% of the sales price exceeding a target price (with a 20% margin); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.&nbsp;&nbsp;&nbsp;&nbsp; In addition to the above, a bonus of 5% of the higher of the adjusted EBITDA for G1 and 60% of the combined adjusted EBITDA of G1 and G2.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.&nbsp;&nbsp;&nbsp;&nbsp; For the warranty and aftermarket support services with respect to Covered Products, TUS will receive 1% of the sales price.

The total amount we owe under this agreement under (A) parts (1) and (2) above of the commission under the marketing and sales services in the sales agency and aftermarket services with respect to Covered Products and (B) certain amounts due under the IP License Agreement between Evervolt Green Energy Pte Ltd, as permitted assignee to Trina Parent (the previous licensor), and G1 dated July 16, 2024 as amended on December 23, 2024 and December 29, 2025, will not exceed $200 million per year. This agreement will remain in effect until the later of December 23, 2029, or the date when all obligations under the Credit Agreement are fully repaid or discharged.

In connection with the Sales Agency Agreement, on August 13, 2025, the parties thereto entered into Amendment No. 1 to the Sales Agency Agreement (the "First Amendment"), which provides that any and all service fees that are payable or that become payable by G1 on or following the date of the First Amendment, shall be deferred, without interest, and no payments shall be due with respect to such service fee, until the earlier of (i) thirty (30) days following the date on which G1 or its Affiliates receives a cash payment with respect to any Advanced Manufacturing Production Credits, as defined in Section 45X of the Internal Revenue Code of 1986, as amended (the "IRC"), enacted pursuant to Section 13502 of Public Law 117-169, 136 Stat. 1818 (August 16, 2022), commonly known as the Inflation Reduction Act of 2022 ("45X Tax Credit"), including as a result of any election under Section 6418 of the IRC with respect to the relevant 45X Tax Credit and (ii) August 15, 2026.

The conversion price is reduced to $1.70 per share if the 10-day VWAP is less than $2.50 per share, in which case the Series B-1 Preferred Stock would be convertible into approximately 29,411,764 shares of Common Stock (assuming no accrued and unpaid dividends). Conversion of the Preferred Stock is subject to a beneficial ownership limitation of 19.99% of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon such conversion. The Company also agreed to provide certain registration rights with respect to the Preferred Stock and the shares of Common Stock underlying the Preferred Stock. The Preferred Stock carries a dividend rate of 6%, accruing on their issuance and payable in arrears (i) on the dividend date 18 months after their issuance and (ii) every six months after such dividend payment date. Dividends may be payable in cash, securities or other property as may be determined by the Company's board of directors or any of its duly authorized committees.

This proxy statement contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical or current facts contained in this proxy statement are forward-looking statements, including statements regarding our future results and timing of operations, expected performance and financial position, business strategy and plans and objectives of management for future operations, including, among others, statements regarding our anticipated liquidity, growth and profitability strategies, expectations regarding demand for and market adoption of our products, the capabilities, performance and competitive advantage of our technology and products, the timing and anticipated benefits of our manufacturing facilities, and factors and trends affecting our business, including growth and other trends in the markets we serve, and expectations relating to amendment to increase the authorized share capital. Forward-looking statements can be identified in some cases by the use of words such as "believe," "can," "could," "potential," "plan," "predict," "goals," "seek," "should," "may," "may have," "would," "estimate," "continue," "anticipate," "intend," "expect," or the negative of these words, other similar expressions or discussions of strategy, plans or intentions and are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words.

The forward-looking statements contained in this proxy statement are only predictions. We base these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. Forward-looking statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements, or industry results, to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. We believe that these risks, uncertainties and other important factors include, without limitation, the risks set forth in Part I, Item 1A, "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2025, as amended and supplemented by Amendment No. 1 on Form 10-K/A, available on the SEC's website at *www.sec.gov*, and in our other filings with the SEC, including risks related to: (1) our ability to (i) construct and equip manufacturing facilities in a timely and cost-effective manner; (ii) target and retain customers and suppliers; (iii) attract and retain key employees and qualified personnel; (iv) protect our intellectual property; (v) comply with legal and environmental regulations; (vi) compete in international markets in light of export and import controls; (vii) incur substantially more debt; (viii) remediate the material weakness in our internal control over financial reporting or otherwise maintain effective internal control over financial reporting; (ix) qualify for the advanced manufacturing production credit under Section 45X of the IRC; and (x) rely on third-party warranties; (2) the concentration of our operations in Texas and our dependence on a limited number of suppliers; (3) changes adversely affecting the flow of components and materials from international vendors, the costs of raw materials, components, equipment, and machinery; (4) general economic and geopolitical conditions; (5) changes in applicable laws or regulations, including environmental, export control and tax laws and incentives and renewable energy targets, as well as international trade policies, including tariffs, on our products and our competitive position; (6) the outcome of any legal proceedings relating to our products and services, including intellectual property or product liability claims, commercial or contractual disputes, warranty claims, and other proceedings; and (7) the capital-intensive nature of our business and our ability to raise additional capital on attractive terms or service our debt. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements.

In addition, statements that "we believe" and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based on information available to us as of the date of this proxy statement and while we believe such information provides a reasonable basis for these statements, and our management is responsible for the accuracy of such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and you are cautioned not to unduly rely upon these statements.

You should read this proxy statement with the understanding that our actual future results, levels of activity, performance and achievements may be materially different from what we expect. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by these cautionary statements.

These forward-looking statements speak only as of the date of this proxy statement. Except as required by applicable law, we do not assume any obligation to update any forward-looking statement, whether as a result of any new information, future events or otherwise.
