Accelerant Shareholders to Receive $20.25 per Share in Cash, Representing a 49% Premium to Accelerant’s Closing Share Price on August 12, 2026

Accelerant (NYSE:ARX), the data-driven risk exchange platform transforming the specialty insurance marketplace through the Accelerant Risk Exchange, today announced that it has entered into a definitive agreement with Thoma Bravo to become a privately held company in an all-cash transaction with an enterprise value of more than $4 billion.

Under the terms of the agreement, Accelerant Class A and Class B stockholders will receive $20.25 per share in cash, representing a 49% premium to Accelerant’s closing share price on August 12, 2026.

"Accelerant has been building the preeminent specialty insurance marketplace since our founding in 2018," said Jeff Radke, Chairman and CEO of Accelerant. "Returning to private ownership with Thoma Bravo’s technology and software expertise, coupled with its vast financial and strategic resources, will enable us to make investments that further position our unique, data fueled platform to be the rails on which specialty insurance runs."

"We are pleased to have reached this agreement with Thoma Bravo." said Karen Meriwether, Chair of the Special Committee. "The Special Committee believes this transaction recognizes the valuable platform and ecosystem that the Accelerant team has built, and provides immediate value to shareholders at a substantial premium."

"We have immense admiration for Jeff, his team and the business they’ve built," said A.J. Rohde, Senior Partner at Thoma Bravo. "As the MGA market continues to grow, underwriters are looking for a committed technology-forward partner who can unlock rapid program growth and underwriting innovation. We’ve invested in insurance technology and data businesses for years, and we're excited to work alongside the entire Accelerant team."

"Accelerant has built something rare in specialty insurance," said Matt LoSardo, a Principal at Thoma Bravo. "Its risk exchange connects underwriters with risk capital and gives both sides the data to price risk better than either could alone. We look forward to partnering with Jeff and the team to invest behind the technology, data and capital capacity to support Accelerant’s next phase of growth."

Transaction Details

The Company’s Board of Directors established a Special Committee comprised solely of independent and disinterested directors to review and consider the transaction. The Special Committee unanimously recommended approving the transaction which was then unanimously approved by Accelerant’s Board of Directors. Under the terms of the agreement, Accelerant Class A and Class B shareholders will receive $20.25 per share in cash. Under certain circumstances, if the closing of the transaction is delayed by certain pending insurance regulatory approvals, shareholders will receive a ticking fee accruing at a rate of 6% per annum for a period specified in the agreement.

The transaction, which is currently expected to close in the first half of 2027, is subject to customary closing conditions, including approval by the shareholders of the Company, and satisfaction of required regulatory approvals. Entities affiliated with Altamont Capital Partners holding shares representing approximately 82% of the Company’s outstanding voting rights have agreed to vote their shares in favor of the transaction. The transaction is not subject to any financing condition as Thoma Bravo has provided an equity commitment to fund the purchase.

Upon completion, Accelerant will become a private company, and its common shares will no longer be listed nor traded on the New York Stock Exchange.

Altamont Capital Partners, Accelerant's largest investor, and the Company's founders, intend to retain equity ownership alongside Thoma Bravo, the terms of which will be finalized prior to closing.
