Jeff Radke told the market what he had built. August 13, 2026. Atlanta. The Accelerant Risk Exchange, he said, is "the rails on which specialty insurance runs." Thoma Bravo put $20.25 a share on those rails. More than $4 billion. A 49 percent premium to the close the day before.

Accelerant is not a name on a policy. It is the marketplace that hooks specialty underwriters to risk capital. Radke has been building it since 2018. Matt LoSardo, a Thoma Bravo principal, said the quiet part on the same page: the exchange "connects underwriters with risk capital and gives both sides the data to price risk better than either could alone." $20.25 is a price on that hookup. Class A and Class B. All cash.
Karen Meriwether chaired the special committee that reviewed it. The committee recommended it. The board approved it. Meriwether said the number "provides immediate value to shareholders at a substantial premium." Immediate value is the $20.25. The argument for taking it private is the platform. A.J. Rohde, a senior partner at Thoma Bravo, said underwriters want a technology-forward partner who can unlock program growth. That is the buyer's sentence. Thoma Bravo's own page calls the firm the world's largest software-focused investment shop, more than $172 billion under management as of March 31, 2026. The 8-K puts the buyer vehicles under Thoma Bravo Discover Fund V.
The close is still the first half of 2027. Shareholders have to approve it. Insurance regulators have to approve it. Entities affiliated with Altamont Capital Partners hold about 82 percent of the vote and agreed to vote yes. Altamont and the founders intend to keep equity. There is no financing condition. If certain insurance regulatory approvals drag, shareholders get a ticking fee at 6 percent a year. The New York Stock Exchange ticker comes off when it closes. It has not closed.
A software fund does not pay a 49 percent premium for an underwriting brand. It pays that premium for the pipe, the data, and the capital hookup, and for the bet that the programs riding those rails will keep riding them after the ticker goes dark.
Monday morning, for the insurance company that puts specialty paper on that exchange, and for the operator whose risk ends up there, the questions are the ones a claims desk already knows how to ask a panel firm.

Who owns the data. Submission history, loss curves, capacity, pricing marks: that is the book a risk exchange builds by running other people's specialty paper. After a close that book sits inside a private company. LoSardo already said both sides get the data to price risk better than either could alone. The buyer of the exchange buys that pipe. The companies that fed it funded the set.
Who sets the fee. $20.25, a 49 percent premium, and more than $4 billion have to be earned. A marketplace earns a return as a toll, as a spread on capital, as a thicker take on the same submission, or as a thinner service wrapped in better software. Ask which one it will be, in writing, before the ticker disappears.
Who writes the rules. Rohde's sentence is the operating plan: a technology-forward partner, rapid program growth, underwriting innovation. That can look like more capacity. It can also look like a software firm sitting between the underwriter and the capital. Altamont already holds most of the vote. Thoma Bravo is buying the rest of the control stack, with Altamont and the founders intending to stay on the cap table. Who still sees the book. Who gets cut. Who can change the exchange after the special committee is gone and the only outside clock left is an insurance regulator.
Independence here is not a bar rule. It is who can change the marketplace the rest of the specialty book is standing on.
The 8-K is the paper. Accelerant Holdings. Date of earliest event August 13, 2026. Cherry Tree BidCo. Merger Sub merges in. The company survives as a wholly owned subsidiary. None of that has happened. It is the mechanics of a close that is still sitting in the first half of 2027.
Radke has been building a specialty insurance marketplace since 2018. On August 13 he told shareholders that going private with Thoma Bravo's software shop would let him invest so the platform can be the rails. That is his word. The $20.25 is the market's word. The 49 percent premium is what public holders get for handing those rails to a software fund.
The companies already on the track will live with the owner who paid it.
