AUSTIN, Texas, and NEW YORK – T1 Energy Inc. (NYSE: TE) (“T1,” “T1 Energy,” or the “Company”) appreciates the ongoing support for the current draft of the budget bill under consideration in the U.S. Senate, which includes the 45X Production Tax Credit. This credit promotes domestic production of solar modules and components and has received backing from both houses of Congress, with a provisional extension through 2032. T1 Energy anticipates participating in and benefiting from the growth of a domestic solar supply chain.

The proposed budget bill retains the transferability and stackability of the 45X credits, both of which T1 considers crucial incentives for the domestic solar manufacturing industry. These features will provide significant financing options and flexibility for T1, potentially enhancing the Company’s EBITDA generation through stacked 45X credits from integrated U.S. cell and module production.

These provisions in the budget bill are vital as T1 advances several capital formation initiatives to fund the development of G2_Austin, its planned 5 GW U.S. Solar Cell Facility in Milam County, Texas. The finalization of the budget bill and a supportive policy framework for T1’s domestic content strategy are critical steps to progress in project financing, customer offtake discussions, and other funding initiatives. The Company aims to complete the capital formation process and start construction at G2_Austin in Q3 2025.

T1 Energy is also assessing a recently proposed excise tax on certain solar projects that incorporate a significant percentage of components from a Foreign Entity of Concern (FEOC) nation. As an agile company, T1 believes it can align its manufacturing operations with the final version of the bill. If the FEOC tax remains in the final draft, T1 expects to provide American-made solar modules exempt from this tax. Should the provision be removed, T1 will proceed with its plans to deliver high-efficiency, cost-competitive modules from G1_Dallas, its operational 5 GW Solar Module Facility, while exploring its most promising value creation opportunities.

“Solar energy strengthens our electric grids and lowers electricity prices for Americans and American businesses. We see this every day on the Texas grid, as solar supports the state’s dynamic population and economic growth through abundance and affordability. Solar is not a problem; it’s an answer. And it needs to be made in America,” stated T1’s Chairman and CEO, Daniel Barcelo.
