NEW YORK, June 17, 2026, 12:44 (EDT)
- T1 Energy stock jumped nearly 12% to $9.67 by midday, with more than 20 million shares traded.
- T1 Energy Inc. said its G1_Dallas solar module plant got an “A” in a bankability review by Intertek CEA. T1 Energy Inc.
- Bernstein SocGen Group started coverage with a Market Perform and set a $9 price target. Shareholders were set to vote on whether to double the number of authorized common shares.
T1 Energy shares jumped Wednesday after the solar maker said an outside reviewer gave its Texas module facility top marks. The move comes as new Bernstein coverage singled out T1’s push to set up a domestic solar supply chain.
Shares rose 12.1% to $9.67 by midday in New York, after hitting $9.69 earlier. The stock saw heavier activity and outperformed the broader market. It has turned into a volatile trade tied to U.S. solar manufacturing policy.
T1 wants to shift from just running one operating module factory to building out a U.S. solar operation with cells, modules and storage, aimed at utility and data center demand. A bankability assessment, the outside review that customers and lenders use to check if a supplier is up for long-term contracts and warranties, is part of that effort.
T1 said Intertek CEA reviewed its 5-gigawatt G1_Dallas facility in April, looking at production, process controls and quality management. CEO Dan Barcelo called the grade “a meaningful independent confirmation” of T1’s efforts in Texas. He said G1_Dallas is designed to turn out modules “customers can rely on for decades to come.” T1 Energy Inc.
The company said Phase 1 of the G2_Austin solar cell factory should bring 2.1 GW of yearly capacity. Cell output is set to begin in Q4 2026. One gigawatt equals a billion watts of generation capacity.
Bernstein didn’t go full bull in its latest note. The broker began T1 at Market Perform, gave it a $9 target. That’s under where T1 traded Wednesday. Bernstein pointed to potential gains from a second plant but flagged uncertainty over a First Solar patent fight tied to TOPCon, a high-efficiency silicon solar-cell tech.
There’s a question about capital hanging over the stock. T1’s annual meeting kicked off at noon EDT, with a vote set on whether to boost the company’s authorized common shares to 1 billion, up from 500 million. Companies use authorized shares as an upper limit on what they can issue. Raising that ceiling gives the board more room to fundraise, but can lead to worries about dilution for existing investors.
T1 is pushing past just solar panels. The company said on June 3 it would buy KORE Power in a deal worth about $32 million, including equity, cash and assumed debt. The purchase gives T1 a foothold in battery energy storage systems—so-called BESS, which are big batteries that store and release power—and moves it into AI data-center infrastructure. KORE Power CEO Jay Bellows said the deal should deliver customers “a one-stop solution for generation, storage, system design, and ongoing operations.” T1 Energy Inc.
Peer moves split. First Solar lost nearly 0.8%. Canadian Solar rose about 2.0%. Both companies are relevant here—First Solar leads U.S. thin-film and is active in patent fights over TOPCon, while Canadian Solar is one of the global module makers operating in the related competitive and legal space.
The move isn’t without risk. First Solar’s Delaware patent suit targets T1 Energy and related T1 firms, though the case is paused for now while the International Trade Commission looks at the matter. If T1 stumbles on the patent dispute, its G2_Austin build, financing, supplier checks or tax-credit status, shares could drop fast after the recent double-digit gain.
