T1 Energy Inc. shares retreated in early premarket trading Thursday, giving back some of the prior session's gains after a regulatory filing revealed that former strategic partner Trina Solar (Schweiz) AG had significantly reduced its holdings in the U.S. solar company.
The stock was last seen at $10.53 before Thursday's opening bell, down 3.9% from Wednesday's close of $10.96, according to Google Finance data. Wednesday's session had been particularly strong, with shares surging 4.88% and touching a 52-week high of $11.28 during intraday trading.
Trina's Block Sale
According to a Schedule 13D/A filing published May 26, Trina Solar (Schweiz) AG sold a total of 22.5 million T1 Energy shares over two days—May 21 and May 22. The first tranche consisted of 13 million shares, followed by an additional 9.5 million shares the next day. After completing these transactions, Trina retained 30.65 million shares, representing 11.0% of T1's outstanding common stock, with sole voting and dispositive power over those remaining shares.
The sale prices ranged from $7.74 to $9.43 per share, all well below Wednesday's closing price of $10.96. A separate Form 4 filing provided further granularity, noting that 9,479,904 shares were moved on May 22 at an average price of $8.1347.
Evolving Relationship
The latest filing sheds additional light on the shifting dynamics between T1 Energy and its former Chinese partner. Trina had previously held a director nomination right under a cooperation agreement, but that arrangement was modified with an amended contract in December 2025. The Trina-nominated director subsequently stepped down from the board on March 30.
This development comes at a critical juncture for T1 Energy as it positions itself as a domestic U.S. solar supply chain player. On May 12, the company reaffirmed that construction at its G2_Austin facility—a 2.1-gigawatt first-phase solar cell factory—remains on schedule, with cell production still targeted to begin in the fourth quarter. One gigawatt represents enough power capacity for industrial-scale output, not rooftop solar.
CEO's Vision
T1 Energy CEO Dan Barcelo emphasized the company's strategic priorities: profitably operating the G1_Dallas facility, securing funding for the G2_Austin expansion, and executing the buildout. He described the company as “an integrated, homegrown U.S. solar and storage powerhouse.” Production guidance for G1_Dallas in 2026 remains unchanged at 3.1 GW to 4.2 GW, as reported by GlobeNewswire.
Policy and Market Factors
The company's business model hinges on Section 45X production tax credits, which provide U.S. tax incentives for manufacturers of clean-energy components. It also depends on compliance with Foreign Entity of Concern (FEOC) rules, which can restrict eligibility for those benefits. FEOC regulations are designed to target companies under control of, or linked to, certain foreign governments, with China being a primary focus.
Roth Capital Partners analyst Philip Shen dismissed a recent short-seller report targeting T1 Energy, calling the company “a model for what the Trump administration may want in a domestic manufacturer that is transferring advanced technology and capacity to the US,” according to Sherwood News. Shen characterized the post-short-report selloff as a potential buying opportunity.
The broader market is grappling with numerous variables that could impact T1 Energy: factory ramp-up timelines, debt financing terms, the fate of clean-energy tax credits, and evolving trade policy. The company noted this month that key factors for 2026 include customer demand, a potential Section 232 decision from the U.S. Commerce Department regarding foreign-sourced polysilicon and derivatives, and questions surrounding IEEPA tariffs imposed under emergency economic powers legislation.
Solar stocks remain active in this policy-driven trade, though performance has been uneven. First Solar gained 1.38% on Wednesday, while Canadian Solar announced this month that it has begun trial runs at its Jeffersonville, Indiana solar cell plant, targeting regular output by July 2026.
