The amendment also adds a potential transaction award. If the company signs a definitive agreement for a significant merger or acquisition that Mr. Matrai advises on, he will receive restricted stock units with a grant date fair market value of $250,000 under the 2021 Equity Incentive Plan. These RSUs vest in three equal annual tranches and continue to vest even if his consulting role or board position ends, except in a termination for Cause.

TRINA SOLAR (SCHWEIZ) AG, a 10% owner of T1 Energy Inc. (TE), reported acquiring 4,274,704 common shares on January 21, 2026. The shares were issued to this holder at a price of $1.7 per share under anti-dilution rights contained in a Transaction Agreement dated November 6, 2024. Following this issuance, the reporting person beneficially owns 53,152,664 common shares, held directly.
Trina Solar (Schweiz) AG has updated its ownership in T1 Energy Inc. through an anti-dilution subscription. The investor now beneficially owns 53,152,664 shares of T1 Energy common stock, representing 19.6% of the outstanding common shares, based on 270,572,801 shares outstanding as of January 22, 2026.
The change stems from anti-dilution rights granted as part of T1 Energy’s acquisition of T1 G1 Dallas Holding and related subsidiaries, referred to as the Trina Business Combination. After T1 Energy entered into an Amended and Restated Stock Purchase Agreement on October 31, 2025 and issued new common and preferred shares, Trina Solar (Schweiz) exercised its Trina Anti-Dilution Rights.
Under those rights, Trina Solar (Schweiz) subscribed for an additional 4,274,704 T1 Energy common shares at a subscription price of $1.70 per share. This subscription closed on January 21, 2026 and increased the reporting person’s stake while maintaining its position against dilution from the broader financing transactions.
T1 Energy Inc. filed an automatic shelf registration statement on Form S-3ASR and a prospectus supplement covering the resale of 14,274,704 shares of common stock and a warrant to purchase 7,000,000 shares at a purchase price of $0.01 per share by named selling securityholders. These shares include stock previously issued to Trina Solar (Schweiz) AG in private placements and shares that may be issued upon exercise of a warrant issued to Stellar Hann Investment Ltd. The filing explains that the prospectus supplement itself does not sell any securities, and any resale by the selling securityholders would not generate proceeds for the Company. T1 Energy also provides a legal opinion from Skadden, Arps, Slate, Meagher & Flom LLP on the validity of the common stock and enforceability of the warrant as an exhibit to this report.
T1 Energy Inc. has filed a prospectus supplement enabling the resale of 14,274,704 shares of common stock, a warrant to purchase 7,000,000 shares, and 7,000,000 shares issuable upon exercise of that warrant by existing holders. These securities were issued in prior private placements, including 3,000,000 shares to Trina Solar (Schweiz) AG as partial payoff of indebtedness, 4,274,704 anti‑dilution shares to Trina, and a penny warrant to Stellar Hann Investment Ltd. with a $0.01 exercise price per share exercisable from March 10, 2026 to September 10, 2030.
The company will not receive proceeds from any resale, but would receive cash only if the warrant is exercised for cash. Trina remains a major shareholder, and T1 Energy has also issued senior convertible preferred stock and convertible notes. The filing highlights a new foreign ownership cap, limiting specified foreign entities to under 4.9% of outstanding common or preferred stock absent board approval, and outlines anti‑takeover and forum‑selection provisions that may make changes in control or stockholder litigation more difficult.
