About T1 Energy Inc.
Source: Item 1 (Business) from the 10-K filed March 31, 2026. Description as filed by the company with the SEC.
ITEM 1. BUSINESS
In February 2025, we changed our corporate name from FREYR Battery, Inc. to T1 Energy Inc. We will not distinguish between our prior and current corporate name and will refer to our current corporate name throughout this Annual Report on Form 10-K. As such, unless expressly indicated or the context requires otherwise, the terms “T1,” “Company,” “we,” “us,” and “our” in this document refer to T1 Energy Inc., a Delaware corporation, and, where appropriate, its subsidiaries.
Overview
T1 Energy Inc. is an energy solutions provider building an integrated U.S. solar supply chain for solar modules to invigorate the United States with scalable, reliable, and low-cost energy. We currently manufacture and sell photovoltaic (“PV”) solar modules in Texas and are constructing our PV solar cell fab in Texas. We are an advanced manufacturer, and our strategy is to manufacture high-domestic content, high-efficiency, technologically advanced solar energy products.
Demand for U.S.-manufactured solar is growing as developers seek to meet surging power demand tied to digital infrastructure development while satisfying domestic content requirements. We believe that the combination of solar and energy storage is the only scalable energy solution capable of meeting projected demand over the next several years. Other sources of power generation, such as new natural gas combined-cycle plants and nuclear power plants, often face multiyear delays before large-scale deployment. We believe solar’s potential is enormous and largely untapped: one hour of Texas sunshine contains more energy than the world uses in one day. In the past, technology governed the growth of energy. Today, energy governs the growth of technology.

We are one of the leading solar manufacturing companies in the United States, primarily selling into the utility-scale market, the largest solar market segment in the U.S. We produce PV solar modules that employ highly energy efficient Passivated Emitter and Rear Contact (“PERC”) and Tunnel Oxide Passivated Contact (“TOPCon”) technologies. Our PV solar module manufacturing facility operating in Wilmer, TX (“G1_Dallas”) has a total annual nameplate production capacity of five gigawatts (“5 GW”). We believe our facility is one of the most technologically advanced PV solar module plants globally and has achieved annualized run rates above nameplate capacity. To further expand our U.S. manufacturing footprint, we began construction in December 2025 of the first 2.1-gigawatt phase of our solar cell manufacturing fab in Milam County, Texas (“G2_Austin”). This facility is anticipated to begin production by the end of 2026 of high-efficiency TOPCon solar cells that will be used in the solar modules manufactured at G1_Dallas.
T1 is focused on establishing an end-to-end American polysilicon solar supply chain, and we are executing that vision by partnering with great American companies, including Corning, Hemlock Semiconductor, Nextpower, Treaty Oak and others. This journey began on November 6, 2024, when we announced that we had entered into an agreement (the “Transaction Agreement”), to acquire all the shares of capital stock of Trina Solar (U.S.) Holding Inc., a Delaware corporation and related subsidiaries (collectively “Trina Solar US Holding”). The transaction closed on December 23, 2024 (the “Trina Business Combination”). As part of the Transaction Agreement, we acquired G1_Dallas from Trina Solar US Holding and entered into a series of commercial support and technology licensing agreements with Trina Solar. Following the acquisition of G1_Dallas from Trina Solar, a global solar company based in China, T1 Energy dedicated significant resources in 2025 with the goal of achieving full compliance with new restrictions on energy tax credits under the One Big Beautiful Bill Act (“OBBBA”). On December 29, 2025, we entered into a series of transactions with Trina Solar and other parties that, among other things, are intended to allow T1 to comply with the restrictions on energy tax credits imposed under Sections 7701(a)(51), 7701(a)(52), 45X(d)(4), 45Y(b)(1)(E) and 48E(b)(6) of the Internal Revenue Code of 1986, as amended (the “IRC”), following the enactment of the OBBBA on July 4, 2025 (the “FEOC Restructuring”).
