T1 Energy’s stock has more than sextupled over the past twelve months, but the forces driving that rally are sharply divided. On one side, a hedge fund snapped up 10 million shares on May 26, triggering a 23% single-day surge and a fresh 52-week high of $9.85. On the other, Trina Solar (Schweiz) AG — once a strategic partner — quietly sold down its stake in May after receiving a large, heavily discounted share issuance in January. The conflicting signals leave investors parsing whether institutional confidence or insider exits will shape the next leg of the story.
The hedge fund’s purchase pushed the stock past a technical resistance level near $9, with volumes lifting the market capitalisation of the Texas-based solar module maker to roughly $2.6 billion. But the same week, Trina filed a Schedule 13D/A showing it held 30,652,664 shares as of May 22 — down from 53,152,664 after the January issuance. That earlier transaction, disclosed in a May 26 SEC filing, awarded Trina 4,274,704 new shares at $1.70 each under anti-dilution rights stemming from a November 2024 agreement. The shares represented about 1.5% of the outstanding float, and the deal also cost Trina its board seat: a revised cooperation agreement on December 29, 2025 removed that right, and Trina’s director resigned on March 30.
A $225 Million Factory and a Funding Gap
The equity shuffle comes as T1 Energy races to complete a 2.1 GW solar cell factory in Austin, Texas. Phase 1 construction is on schedule, with concrete work beginning in April and first cell production pencilled in for the fourth quarter of 2026. The company estimates total capital needs for the initial phase at $225 million.
To bridge that, it upsized a convertible bond issuance in April from $125 million to $160 million. Net proceeds were reported at $151.6 million in one filing, while a separate disclosure put the net inflow at $174.7 million — a discrepancy that still leaves a shortfall of roughly $50 million. T1 Energy has said it is pursuing a comprehensive financing solution in the second quarter that will include a significant debt component.
Should investors sell immediately? Or is it worth buying T1 Energy?
Cash and equivalents stood at $123.7 million at the end of March, of which $46.4 million was unrestricted. The Austin facility, known as G2_Austin, requires further equipment and infrastructure spending, and the convertible notes carry a 4% coupon and mature in 2031.
Profitability Emerges — but So Do Short-Seller Allegations
Against the financing backdrop, the company posted a net loss of $21.4 million for the first quarter, or $0.08 per share, but net income from continuing operations reached $3.9 million. Adjusted EBITDA hit $9.1 million — comfortably above consensus estimates, which had called for a loss. The turnaround stems from the ramp-up of its G1 Dallas module factory in Wilmer, Texas, where production and sales beat forecasts. A shift toward fixed-margin and cost-plus offtake agreements, rather than spot-market sales, is stabilising revenue during the scale-up.
That strong operational showing, however, has drawn scrutiny from short-sellers. Fuzzy Panda Research published a critical report alleging T1 Energy violates Foreign Entity of Concern (FEOC) rules. The research firm points to possible undocumented ties to Trina Solar and the sale of intellectual property to Evervolt, a transaction the company says was intended to ensure compliance. The allegations create a tug-of-war between bearish speculators and the new institutional buyer.
Technicals and Next Milestones
The stock last traded at €9.40, just below Wednesday’s 52-week high of €9.45. It advanced somewhere between 25% and 26% over the past week and roughly 125% to 126% over the past month, with annualised 30-day volatility running at about 143% to 145%. The next concrete checkpoints are the promised financing solution this quarter and the first cell production before year-end. Until then, the question remains whether T1 Energy can fund its factory expansion without further diluting existing holders — or whether the short-seller report will delay the institutional momentum that has powered the rally.
