T1 Energy Reports Q4 and Full-Year 2025 Results: Strong Operational Momentum, Capital Initiatives, and Forward Guidance

Key Highlights for Investors

• G2_Austin Solar Cell Fab Construction On Track: Construction of the 2.1 GW Phase 1 of T1’s flagship U.S. solar cell facility in Austin is progressing according to schedule, with steel erection planned for April 2026. The company has already reduced the remaining capital spend for Phase 1 to approximately \$350 million through early investments and is targeting production commencement in Q4 2026.
• Record Production and Sales at G1_Dallas: Q4 2025 saw record module production of 1.13 GW and net sales of \$358.5 million at the G1_Dallas facility, adding two major utility-scale customers. Full-year 2025 production reached 2.79 GW, aligning with company guidance.
• Significant Capital Formation Progress: T1 Energy has secured over \$440 million in strategic capital and is actively working to close the remaining \$350 million for G2_Austin Phase 1 by early Q2 2026.
• Strategic Tax Credit Milestones: T1 executed its first sale of Section 45X production tax credits for \$160 million at \$0.91 per dollar to a leading financial institution, confirming its eligibility under new U.S. Treasury guidance on Foreign Entity of Concern (FEOC) restrictions. A series of transactions, including debt repayment and restructuring, were completed to comply with FEOC requirements.
• Major Offtake Agreement and Customer Expansion: A three-year supply contract was signed with Treaty Oak Clean Energy for a minimum of 900 MW of modules from G2_Austin, highlighting commercial momentum.
• Leadership Changes: Veteran energy executive Robert Hammond joined the Board as an independent director, while Tore Ivar Slettemoen and Mingxing “Charles” Lin resigned.

Strategic Initiatives & Business Outlook (2026–2027)

• T1 is maintaining its 2026 production and sales guidance of 3.1–4.2 GW, sourcing non-FEOC certified cells from international suppliers during the “bridge year” before G2_Austin is operational.
• 3 GW of G1_Dallas production already contracted for 2026 via cost-plus or fixed margin agreements.
• Potential swing factors for 2026 include U.S. Section 232 investigation outcomes, ability to source additional third-party cells, and customer safe harboring under new regulations—each could materially affect sales, pricing, earnings, and cash flow.
• Upon completion of G2_Austin Phase 1 (2.1 GW), T1 expects annualized run-rate Adjusted EBITDA of \$375–\$450 million by 2027. Fully integrated production of 5 GW each at G1 and G2 could yield \$650–\$700 million annualized run-rate Adjusted EBITDA.

Other Noteworthy Developments

• Regulatory and Capital Structure: T1’s compliance with FEOC and Section 45X ensures continued eligibility for advanced manufacturing tax credits, which is a competitive advantage as U.S. energy policy evolves.
• Public Offerings: In December 2025, T1 priced public offerings of \$161 million in convertible senior notes due 2030 and 32.5 million shares of common stock at \$4.95 per share, bolstering the balance sheet.
• Risk Factors: T1 cautions on risks including construction timelines and costs, supplier and customer concentration, ability to qualify for government incentives, the capital intensity of its business, and broader economic and policy uncertainties.

Implications for Shareholders and Potential Share Price Impact

• Positive Catalysts: On-schedule construction of G2_Austin, a record-breaking Q4 for production and sales, and successful execution of tax credit sales and major customer contracts all position T1 for significant topline and margin growth from 2026 onward. Strategic partnerships and strong capital formation efforts bolster long-term U.S. solar leadership aspirations.
• Risks and Cautions: The company continues to operate at a net loss and is exposed to regulatory, supply chain, and capital market risks. Any delays or adverse rulings on FEOC, Section 232, or U.S. tax credits could materially impact the company’s trajectory. Investors should monitor capital formation and G2_Austin construction milestones closely.
• Leadership Changes: The addition of Robert Hammond as an independent director brings deep energy industry experience, which could further strengthen governance and execution.

Conference Call Details

T1 Energy will hold a conference call on March 31, 2026, at 8:00 am EDT to discuss the results. Presentation materials are available at https://ir.t1energy.com/.
