ATCO Atlas Corporation

Poseidon Acquisition Corp., on behalf of a consortium composed of David L. Sokol, Chairman of the Board of Directors of Atlas Corp. (NYSE: ATCO) (“Atlas” or the “Company”), certain affiliates of Fairfax Financial Holdings Limited (collectively, “Fairfax”)(TSX: FFH and FFH.U), the Washington Family, and Ocean Network Express Pte. Ltd., a global container, transportation and shipping company (the “Consortium”), announced today it believes it has made meaningful progress in its discussions with the Special Committee of the Board of Directors of Atlas to acquire all of the outstanding common shares of Atlas that the members of the Consortium do not already own or control for $15.50 per share in cash, plus payment of all ordinary course third quarter and fourth quarter 2022 dividends regardless of the timing of any closing (the “Proposed Transaction”). There is no binding agreement with respect to the Proposed Transaction, and negotiations remain subject to significant contingencies, including completion of due diligence by the Consortium (expected to be commenced promptly), the negotiation and execution of a mutually acceptable definitive agreement, and confirmation and documentation of fully committed financing. In addition, the closing of the Proposed Transaction, if a definitive agreement is reached, would be contingent upon the approval of holders of a majority of the Atlas common shares not owned by Consortium members and the satisfaction of additional mutually acceptable closing conditions to be contained in a definitive agreement. The Consortium does not expect to make any further announcements or updates unless and until a definitive agreement is executed or discussions with the Special Committee are terminated.
