Highlights

• On April 30th, T1 achieved term conversion of the G1 Dallas construction loan to a $235 million term loan in line with the previously communicated timeline

• T1 produced 443 MW of PV solar modules at G1 Dallas during Q1 2025, equivalent to 96% of the Company’s production plan    

On April 30, 2025, the construction loan of the G1 Dallas solar module manufacturing facility converted to a $235 million term loan in accordance with the terms set forth by T1’s banking consortium of commercial lenders. The term conversion occurred following T1’s satisfaction of certain conditions precedent, including:

• A formal acknowledgement by each of T1’s solar module offtake customers that facility commissioning had occurred;

• Confirmation by Gray Construction, Inc. that substantial completion of G1 construction had occurred; and

• Certification by an independent engineer that G1 Dallas, with a total annual production capacity of 5 GW, has been installed, tested, and is ready and capable of being used for its intended purposes in a safe manner.

“The term conversion of the G1 Dallas construction loan is an important milestone for T1,” said Evan Calio, T1’s Chief Financial Officer. “With commissioning and third-party technical certification of the facility complete, G1 Dallas is now fully operational, and all production lines have been handed over to our operations team.”
