Aspen Insurance Holdings Limited has provided an information statement to shareholders in connection with the $3.5 billion planned merger with a Sompo Holdings subsidiary.

Last month, a majority of shareholders of Aspen agreed to the consolidation.

Aspen said in a statement today: “On August 27, 2025, the requisite approval for the merger was obtained when certain Aspen shareholders representing a majority of the voting power of the shares of the company delivered a shareholder written resolution to the company.

“Accordingly, no further approval from Aspen's shareholders is required in connection with the merger.

“However, Aspen is pleased to provide to its other shareholders the opportunity to vote their shares in the manner described in the Information Statement.

“Shareholders are encouraged to read and carefully review the Information Statement and are invited to vote their shares in accordance with the instructions provided in the Information Statement.”
