Thoma Bravo agreed to buy Accelerant in a take-private deal valued at more than $4 billion.
Why it matters: The deal puts a large private-equity bet behind insurance infrastructure, where sponsors are chasing better underwriting data and capital efficiency. It also leaves Altamont Capital and Accelerant founders involved, signaling continuity in the business after the buyout.
- Accelerant entered a definitive agreement on Aug. 13, 2026, to be acquired by Thoma Bravo in an all-cash take-private transaction.
- The deal values Accelerant at more than $4 billion enterprise value, with shareholders set to receive $20.25 per share in cash.
- That price is a 49% premium to Accelerant's closing share price on Aug. 12, 2026.
- Altamont Capital Partners, Accelerant's largest investor, and the company's founders intend to retain equity alongside Thoma Bravo.
Thoma Bravo is buying specialty insurance platform Accelerant in an all-cash take-private deal valued at more than $4 billion, according to the companies.
Accelerant shareholders are set to receive $20.25 per share, a 49% premium to the company's closing price on Aug. 12, 2026. The transaction is expected to close in the first half of 2027, pending shareholder and regulatory approvals.
The structure is notable: Altamont Capital Partners, Accelerant's largest investor, and the company's founders plan to retain equity ownership alongside Thoma Bravo, with final terms to be set before closing. PE Hub reported that the buyout includes that equity rollover structure.
Altamont controls about 82% of Accelerant's outstanding voting rights and has agreed to vote in favor of the transaction. Accelerant canceled its planned Aug. 13, 2026 earnings conference call because of the announcement.
Accelerant says its platform connects specialty insurance underwriters with risk capital partners through a data-driven risk exchange. Thoma Bravo said underwriters are looking for a technology-forward partner that can support program growth and underwriting innovation.
By the numbers
- More than $4 billion - Enterprise value for the Accelerant take-private.
- $20.25 - Cash offer per Accelerant share.
- 49% - Premium to Accelerant's Aug. 12, 2026 closing share price.
Yes, but: The exact post-deal ownership split was not disclosed, and the transaction still needs shareholder and regulatory approvals.
What's next: The deal is expected to close in the first half of 2027.
