T1 Energy’s Core Solar Business Turns Profitable as $225 Million Funding Clock and Patent Battle Intensify

Solar firm T1 Energy secures shareholder nod to double shares, seeks $225M for Texas plant, posts 232% revenue surge but battles patent suit and probe.

The clock is ticking for T1 Energy. The solar manufacturer must secure a $225 million financing package by the end of the second quarter to keep its second Texas factory on track, and shareholders have just handed management a powerful new tool to raise the cash. At a mid-June annual meeting, investors approved a doubling of authorized common shares to one billion, giving the board far greater flexibility for equity-linked deals. The stock, which had touched above $12 in early June, has since slid to around €7.90 before settling at €7.35 by the latest trading session — a reflection of the mounting uncertainties.

Yet beneath the surface of headlines about patent lawsuits and funding deadlines, the company’s core operations are delivering a surprise. First-quarter 2026 revenue surged 232% year-on-year to a record $177.6 million, driven by growing output from the G1_Dallas plant. The continuing business posted a net profit of $3.9 million, with adjusted EBITDA of $9.1 million. The headline consolidated loss of $21.4 million came almost entirely from discontinued operations, which alone contributed $24.3 million in red ink. A shift toward fixed-price and cost-plus contracts has improved margin visibility, and the Dallas facility recently earned an “A” bankability rating from the independent auditor Intertek CEA, a seal of quality that should ease the signing of large utility-scale supply agreements.

The Dallas factory, which is on track to produce up to 4.2 gigawatts this year, is now fully self-sustaining. The bigger challenge lies 200 miles south in Austin. First-phase construction of the G2_Austin plant is on schedule to begin cell production by the end of 2026, but the project still needs the $225 million that T1 Energy had flagged after issuing a convertible bond in April. Management has indicated that the new funding will be heavily debt-based, yet the authorized share increase also opens the door to equity-linked tranches if necessary.

While the manufacturing engine is humming, legal storm clouds are gathering on two fronts. First Solar has accused T1 Energy of infringing its patents on the critical TOPCon module technology, and the US International Trade Commission is now investigating the case. A negative ruling could lead to an outright ban on imports of TOPCon cells into the United States — a blow that would leave T1 Energy without its flagship product. Separately, the company is the subject of a regulatory probe into alleged safety violations, raising the specter of heavy fines and operational disruptions. In a separate legal risk that predates both, the research firm Fuzzy Panda has alleged that T1 Energy has ties to a sanctioned supplier — a charge that could jeopardize the Section 45X tax credits that underpin the entire US manufacturing strategy.

The stock market has taken notice. The shares have lost 22% in the past month, falling from the June high of €11.00, and implied volatility has soared to an extreme 150%. Bernstein analyst Sunaina Ocalan initiated coverage with a Market Perform rating and a $9 price target, flagging the patent dispute as the most immediate threat.

In a bid to diversify beyond solar manufacturing, T1 Energy is nearing the close of a $32 million acquisition of KORE Power, a company that brings battery storage systems and infrastructure for AI data centers. Management expects KORE to contribute positive EBITDA by the end of 2026 and to deliver $15 million to $20 million in EBITDA by 2027.

Amid all this, chief technology officer Andreas Bentzen completed a routine share transaction in late June. He received 25,000 shares from an existing compensation plan, of which nearly half were withheld to cover tax obligations. No shares were sold on the open market.

T1 Energy’s full-year 2026 production guidance remains unchanged at 3.1 to 4.2 gigawatts. Whether that target carries credibility will depend heavily on whether the Austin funding comes together before the quarter ends — and on how the ITC rules on a case that could reshape the company’s entire product lineup.
