Accelerant Holdings shares soared 44.2% to $19.58 on Thursday after the specialty insurance company agreed to be acquired by Thoma Bravo and posted better-than-expected second-quarter 2026 results. The move brought the stock close to the previously announced $20.25-per-share cash deal price in the transaction Accelerant has said is valued at $4.4 billion. Second-quarter revenue rose sharply from $219.1 million a year earlier, while Exchange Written Premium increased 23% year over year to $1.32 billion and Third-Party Direct Written Premium represented 47% of Exchange Written Premium volume. The market reaction adds fresh context to a transaction already under review by Julie & Holleman LLP, which has said it is investigating whether the sale is fair to public shareholders and whether conflicts may arise because Altamont Capital Partners is expected to retain an interest in the company after the acquisition closes. The law firm has said its review will examine the sale process, the role of Accelerant's board and special committee, the adequacy of the $20.25-per-share consideration, and whether shareholders are receiving complete and accurate information about the deal.
