Accelerant Goes Private
Thoma Bravo Acquires Accelerant for Over $4 Billion, Taking Insurance Tech Firm Private
Key Points
The merger arrangement calls for Merger Sub to merge with Accelerant, with Accelerant continuing as the surviving company and becoming a wholly owned subsidiary of Parent (a Thoma Bravo affiliate). Parent and Merger Sub are affiliates of Thoma Bravo Discover Fund V, L.P., tying Accelerant’s fate to Thoma Bravo.
Accelerant's shares rose roughly 43.7% in pre-market trading to about $19.56 on the NYSE.
Altamont Capital Partners and Accelerant's founders will retain equity; Altamont-linked entities controlling about 82% of Accelerant's voting rights have expressed support for the deal.
Jeff Radke, Accelerant's Chairman and CEO, said that returning to private ownership with Thoma Bravo’s technology and software expertise will enable investments that position Accelerant’s data-fueled platform to be the rails on which specialty insurance runs.
Thoma Bravo is a software-focused private equity firm with a track record of AI-enabled investments and a portfolio that includes more than 77 software companies; its history includes acquisitions like Dayforce, Anaplan, and SailPoint, highlighting its strategy of growing enterprise software through AI and digital innovation.
Private equity giant Thoma Bravo is buying insurance technology company Accelerant in an all-cash deal worth more than $4 billion, according to Nasdaq. Shareholders will receive $20.25 per share — a 49% premium over Accelerant's closing price on August 12. The deal will take Accelerant off the New York Stock Exchange and make it a privately held company.
Markets responded quickly. Accelerant's stock jumped roughly 43.7% in pre-market trading to about $19.56, Coverager reported. The transaction is expected to close in the first half of 2027.
What the $4 Billion Deal Actually Means
Under the deal, a Thoma Bravo affiliate called "Merger Sub" will merge with Accelerant. Accelerant will survive as a wholly owned subsidiary of the parent company, according to Finviz. The parent and Merger Sub are tied to Thoma Bravo Discover Fund V, L.P., one of the firm's flagship investment vehicles.
Going private means Accelerant's NYSE listing will be terminated. Shareholders get cash at $20.25 per share. But not everyone is cashing out. Altamont Capital Partners — Accelerant's largest investor — and the company's founders will keep a stake in the new private company, Nasdaq reported.
Altamont's 82% Voting Stake Clears the Path
One reason this deal is likely to go through: Altamont-linked entities control about 82% of Accelerant's voting rights. Those entities have already expressed support for the deal, according to San Luis Obispo. That kind of voting power makes shareholder approval close to a certainty.
Altamont's decision to roll its equity into the private company — rather than take the cash — signals confidence in Accelerant's future under Thoma Bravo. The founders are doing the same thing. Both groups are betting the company will be worth more once it can grow without public market pressure.
Thoma Bravo's Bet on Insurance Tech and AI
Thoma Bravo is one of the biggest software-focused private equity firms in the world. Its portfolio includes more than 77 software companies. Past deals include Dayforce, Anaplan, and SailPoint. The firm has a clear strategy: buy enterprise software companies and grow them using AI and digital tools, WIFC reported.
Accelerant fits that mold. The company runs what it calls a "risk exchange" — a data-driven platform that connects specialty insurance underwriters with capacity. CEO Jeff Radke said going private with Thoma Bravo's backing will let the company build "the rails on which specialty insurance runs." The goal is to scale faster without the constraints of being a public company.
Why Accelerant Chose Private Ownership Now
Public markets can be tough for growth-stage tech companies. Quarterly earnings pressure often forces short-term decisions. By going private, Accelerant gets room to invest heavily in its platform without Wall Street watching every quarter. Thoma Bravo's history shows it prefers this playbook — buy, build, and eventually sell or relist at a higher value.
Radke framed the move as a chance to expand Accelerant's risk exchange ecosystem and cement the company's position as a leader in specialty insurance technology. With Thoma Bravo's resources behind it and Altamont staying on as a partner, Accelerant is betting that private ownership is the fastest path to becoming the industry's backbone infrastructure.
