T1 Energy Rides a Volatile Week of Short-Seller Attacks, Analyst Defenses, and a Funding Puzzle

Solar stock swings 40% weekly amid FEOC compliance battle, record EBITDA, and $225M funding gap ahead of shareholder vote.

Few stocks can match the raw volatility T1 Energy has delivered this week, with shares swinging from a double-digit loss to a 26% rally and back again. The solar-cell maker closed Friday at €6.85, down nearly 9% on the day, yet still booked a weekly gain of roughly 40%. Over the past 30 days the stock has surged almost 49%, a reflection of an annualized 30-day volatility north of 130%. The turbulence has been fueled by a pitched battle between bearish short sellers and bullish analysts, each making starkly different calls about the company’s regulatory standing and financial trajectory.

The trigger came on May 19 when Fuzzy Panda Research published a report alleging that T1 Energy does not comply with the FEOC (Foreign Entity of Concern) rules, which govern eligibility for tax credits under the Inflation Reduction Act. According to the short seller, the company booked $41.4 million in tax credits during the first quarter of 2026 without actually having received them. Fuzzy Panda pointed to an IRS guideline from February 2026 that sets the cutoff date for relevant license agreements at July 4, 2025 — yet T1 Energy’s contract with Evervolt was signed on December 29, 2025. The report also noted that the company has received subpoenas from the Department of Justice and the SEC. Shares fell 13% on the news.

The rebuttal was swift. Roth Capital analyst Philip Shen dismissed the report as “misleading,” reiterated his buy rating, and raised his price target from $7 to $15, naming T1 Energy a “Top Pick” for U.S. solar manufacturing. He argued that the company’s license agreements are legally sound and that T1 Energy is fully compliant with FEOC rules. Alliance Global also confirmed its buy recommendation with a target of $8.50. The stock jumped 26% the following day, highlighting how binary the narrative has become for this high-beta equity.

Amid the noise, T1 Energy published its first-quarter 2026 results. Adjusted EBITDA hit a record $9.1 million, while net income from ongoing operations reached $3.9 million. Total revenue came in at $177.6 million. Yet the bottom line remained in the red, with a net loss of $21.4 million — evidence that special charges are still weighing on overall profitability even as the core business strengthens.

The operational outlook centers on the G2_Austin solar cell factory in Texas, a 2.1-gigawatt facility that remains on schedule. Concrete work was completed in April, and the first steel structures went up in May. Production is slated to begin in the fourth quarter of 2026. But the financing picture is incomplete. T1 Energy recently closed a $174.7 million capital raise, yet still faces a funding gap of roughly $225 million to reach full operating capacity.

That gap is likely to dominate the agenda at the annual general meeting on June 17. Shareholders will vote on a proposal to double the number of authorized shares from 500 million to 1 billion, giving management room for future capital measures — but also raising the risk of dilution. Technically, the stock has cooled from its weekly high; the RSI sits at 56, with support seen in the $7.70 to $7.80 area. For T1 Energy, every data point — from IRS rulings to factory costs to analyst targets — carries outsized weight in a market where the line between a breakout and a breakdown is razor-thin.
