**ITEM 1.01 Entry into a Material Definitive Agreement.**

On July 4, 2025, White Mountains Insurance Group, Ltd. ("<u>White Mountains</u>") and its indirect wholly owned subsidiaries WM Monroe Holdings, Inc. ("<u>Buyer</u>") and WM Phoenix GP, LLC entered into a Unit Purchase Agreement (the "<u>Purchase Agreement</u>") with AQ Phoenix Parent, L.P. ("<u>Distinguished Programs</u>" or "<u>Distinguished</u>") and certain other parties thereto. The Purchase Agreement provides that Buyer will acquire, inclusive of White Mountains's existing approximately 1% interest, a 51% controlling interest in Distinguished Programs (the "<u>Transactions</u>") for approximately $230 million in cash.

On July 7, 2025, White Mountains issued a press release announcing the entry into the Purchase Agreement. A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is hereby incorporated by reference into this Current Report.

The Purchase Agreement contains customary representations and warranties as well as covenants by each of the parties, including certain operating restrictions on the conduct of the business of Distinguished during the period from the execution of the Purchase Agreement to the closing of the Transactions. The selling unitholders of Distinguished will indemnify Buyer, and Buyer will indemnify the unitholders of Distinguished for damages arising from breaches of their respective representations and warranties under the Purchase Agreement, subject to certain limitations set forth in the Purchase Agreement. In addition, Buyer has obtained a customary representations and warranties insurance policy covering breaches of the representations and warranties made by Distinguished and certain sellers.

White Mountains has agreed to guarantee Buyer's obligations under the Purchase Agreement.

The Purchase Agreement also contains provisions giving each of Buyer and Distinguished the right to terminate the Purchase Agreement under certain circumstances, including where the closing of the Transactions has not occurred on or before October 2, 2025.

The Transactions are expected to close in the third quarter of 2025. Completion of the Transactions is subject to receipt of certain regulatory approvals and other customary closing conditions. There is no condition with respect to the availability of financing to consummate the Transactions. Completion of the Transactions does not require the approval of the White Mountains shareholders.

On the third anniversary of the closing of the Transactions, certain sellers will have the right to sell additional units (representing 29% of the total units at closing) to White Mountains at the same unit price paid in the Transactions, the total price for which, if exercised in full, is expected to be approximately $130 million. White Mountains will have a parallel right to purchase such units at 1.35x the unit price paid in the Transactions.

The foregoing description of the Purchase Agreement and the other transaction documents related thereto does not purport to be complete and is subject to and qualified in its entirety by reference to the text of such agreements. We intend to file the Purchase Agreement as an exhibit to our next periodic report.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• competitive forces, including the conduct of other insurers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in domestic or foreign laws or regulations, or their interpretation, applicable to White Mountains, its competitors or its customers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other factors, most of which are beyond White Mountains's control.

Consequently, all of the forward-looking statements made in this Current Report on Form 8-K are qualified by these cautionary statements, and there can be no assurance that the actual results or developments anticipated by White Mountains will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, White Mountains or its business or operations.

HAMILTON, Bermuda, July 7, 2025 /PRNewswire/ -- White Mountains Insurance Group, Ltd. (NYSE: WTM) announced today that it has entered into an agreement to acquire a majority stake in Distinguished Programs ("Distinguished" or the "Company"), an MGA and program administrator for specialty property & casualty insurance.

Distinguished is led by industry veterans Bill Malloy, Jason Rotman and Steve Sitterly.

Aquiline Capital Partners, the current controlling equityholder of Distinguished, will remain a significant minority equityholder going forward. Distinguished's current executive management team will continue to lead the business, and each will remain a significant equityholder.

"We've been keen observers of Distinguished's recent progress, and we are pleased to make this acquisition alongside fellow shareholders and a seasoned management team we've known for many years," said Manning Rountree, CEO of White Mountains. "They are well-positioned in an attractive and dynamic market, and we look forward to partnering with the team to capitalize on the organic and inorganic growth opportunities ahead."

"Partnering with White Mountains marks a new and exciting chapter for Distinguished. We believe that their deep insurance expertise, outstanding track record and relevant resources make them the ideal partner for our next phase," said Jason Rotman, President of Distinguished. "Bill, Steve and I look forward to maintaining and increasing the momentum created over the last three years of partnership with Aquiline."

In the transaction, White Mountains will acquire approximately 50% of Distinguished's outstanding equity interests for $230 million. White Mountains currently owns approximately 1% of Distinguished's outstanding equity interests. The transaction is expected to close in the third quarter of 2025. The closing is subject to regulatory approvals and other customary closing conditions.
