On February 11, 2026, T1 Energy Inc., a Delaware corporation (the “Company”) entered into a third amendment (the “Consulting Agreement Amendment No. 3”) to its consulting agreement dated May 14, 2021 with Mr. Peter Matrai, a director of the Company, pursuant to which he serves as a consultant to the Company (the “Consulting Agreement”). The Consulting Agreement Amendment No. 3 extends the term of the Consulting Agreement for an additional period of one (1) year, commencing on January 1, 2026 and expiring on December 31, 2026, unless terminated earlier in accordance with the terms of the Consulting Agreement. Capitalized terms used in this section of this Current Report on Form 8-K but not otherwise defined herein have the meanings given to them in the Consulting Agreement.

Under the terms of the Consulting Agreement Amendment No. 3, the consultant fee remitted to Mr. Matrai shall remain fixed at $30,000 per month. The Company reserves the right to reduce the consultant fee, provided that such decision is mandated by the Compensation Committee of the Board of Directors of the Company, in its sole discretion, as a general reduction applicable to all executive officers of the Company.

The Consulting Agreement Amendment No. 3 also includes a transaction award. If, during the Consultant Term, the Company signs a definitive agreement related to a significant merger and acquisition transaction (as determined in good faith by the Company in its sole discretion) which Mr. Matrai advises on, the Company shall grant him an award of restricted stock units (“RSUs”) covering a number of shares of common stock of the Company with a grant date fair market value of $250,000 (as determined under the Company’s 2021 Equity Incentive Plan). The RSUs shall vest in three (3) equal tranches on each of the first three (3) anniversaries of the grant date. Vesting shall not be conditioned on the Mr. Matrai’s continued service with the Company following the grant date of the RSUs, and any unvested portion of the RSUs shall continue to vest and be settled in accordance with its terms notwithstanding the expiration, non-renewal or termination of the Consulting Agreement or Mr. Matrai’s resignation or removal as a director, except in the event of a termination for Cause.

All other provisions of the Consulting Agreement, including customary confidentiality, non-competition, non-solicitation and intellectual property assignment provisions, remain in effect.
