T1 Energy Inc. announced it is seeking shareholder approval to double its authorized common stock from 500 million to 1 billion shares. The proposal, to be voted on at the 2026 annual meeting, is intended to give the company greater flexibility for future capital raising, potential acquisitions, and equity-based compensation plans. The board would retain the right to abandon the change even if approved by investors.

This announcement comes as the company's stock is on track for its best month on record, having risen 128% in May. The significant rally was partly fueled by a large investment from the hedge fund Situational Awareness LP earlier in the month. Following the month-long surge, the shares saw a slight 2% dip in premarket trading on May 28. Also on this day, a regulatory Form 144 filing indicated a proposed sale of shares by insiders tied to option grants.
