Thoma Bravo Acquires Specialty Insurer Accelerant for $4 Billion

News Desk: Private equity firm Thoma Bravo has struck a deal to take specialty insurance platform Accelerant private in an all-cash transaction valued at more than four billion dollars.

The agreement, announced this week, will see Accelerant shareholders receive 20.25 dollars per share, representing a premium of roughly 49 percent over the stock’s closing price the day before the news broke.

Accelerant, which operates a data-driven risk exchange connecting specialty insurance underwriters with providers of risk capital, listed on the New York Stock Exchange a little over a year ago.

The company said the move back to private ownership will allow it to invest more freely in its technology and platform without the pressures of public markets. Founders and largest investor Altamont Capital Partners plan to retain equity stakes alongside Thoma Bravo.

The transaction is expected to close in the first half of 2027, subject to shareholder approval and customary regulatory clearances, including those from insurance authorities.

Entities affiliated with Altamont, holding about 82 percent of the voting rights, have already agreed to support the deal. Thoma Bravo has provided an equity commitment, so the purchase is not conditioned on financing.

Jeff Radke, Accelerant’s chairman and chief executive, described the partnership as a way to accelerate the platform’s growth with the backing of a firm experienced in technology and software investments.

Thoma Bravo, which manages more than 172 billion dollars in assets, has previously backed insurance technology businesses and sees Accelerant as a key player in the expanding managing general agent market.

Shares of Accelerant jumped sharply after the announcement as investors reacted to the premium offered.

The deal ends a brief chapter as a public company and positions the Atlanta-based firm to focus on scaling its exchange under private ownership.
