T1 and Clearway Execute Strategic Offtake Deal

T1 Energy Inc. (NYSE: TE) (“T1,” “T1 Energy,” or the “Company”) announced this morning a contract to supply independent power producer Clearway Energy Group (“Clearway”) 641MW of solar modules built with domestic solar cells from T1’s G2_Austin solar cell fab. The deal marks a continuation of T1’s commercial strategy to offer customers a traceable and reliable solar supply chain. Leveraging its 5GW solar module facility, G1_Dallas, T1 offers integrated solutions that help clients optimize project schedules, financing, and returns. “We are pleased to be signing a strategic partnership with Clearway, a leading energy developer that is adding needed gigawatts to U.S. grids,” said T1’s Chairman and CEO Dan Barcelo. “Customers such as Clearway seeking high-domestic-content modules are building critical momentum for a ‘Made in America’ supply chain.” This agreement underscores Clearway’s commitment to drive investment in American manufacturing, while maintaining industry-leading traceability, quality, and domestic content standards. “Contracts with top-tier manufacturers like T1 help ensure that Clearway can deliver on our ambitious development pipeline with competitive and reliable projects,” said Frances Cook, Vice President of Procurement at Clearway Energy. “With this deal, we are especially excited to bring domestic cells into future construction, generating American-made power with American-made parts.” T1 continues to increase the domestic content of its modules, as domestic modules with domestic cells are highly valued given rising uncertainty around trade and tariff policy. As part of this strategy, T1 began construction of its G2_Austin solar cell fab in December 2025 and expects the first 2.1GW phase to be producing cells in Q1 2027. T1 expects to offer modules with greater than 60% domestic content in 2027. About T1 Energy T1 Energy Inc.
