As previously disclosed on a Current Report on Form 8-K filed with the Securities and Exchange Commission on November 9, 2023 (the “2023 Form 8-K”) by James River Group Holdings, Ltd. (the “Company”), on November 8, 2023, the Company entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”) with Fleming Intermediate Holdings LLC (“Fleming”) for Fleming’s purchase of JRG Reinsurance Company Ltd. (“JRG Re”) from the Company, which purchase closed on April 16, 2024. Capitalized terms used but not defined herein shall have the meanings assigned to such terms in the Stock Purchase Agreement, which is filed as Exhibit 2.1 to the 2023 Form 8-K.

In accordance with the process set forth in the Stock Purchase Agreement, the Company and Fleming submitted disputed items relating to the Closing Statement, which set forth the post-Closing calculation of the Purchase Price, to an Independent Accounting Firm for final resolution. The disputed items totaled $54.1 million, with Fleming claiming it was entitled to adjust the Closing Purchase Price downward by the full $54.1 million in dispute and the Company asserting that no further adjustment was warranted based on the known facts and the terms of the Stock Purchase Agreement. On April 18, 2025, the Independent Accounting Firm issued its final determination, which resulted in a downward adjustment to the Closing Purchase Price equal to $483,625. Pursuant to the Stock Purchase Agreement, this determination by the Independent Accounting Firm is final, binding and conclusive for all purposes of determining the Purchase Price.

The Company intends to include this $483,625 downward adjustment to the Closing Purchase Price as an additional loss on sale within discontinued operations in its first quarter 2025 financial results to be issued on or prior to May 12, 2025.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
