Information Contained in this Form 6-K Report
On December 16, 2022, Seaspan Corporation (“Seaspan”), a wholly owned subsidiary of Atlas Corp. (the “Company”), announced
that Seaspan has withdrawn its previously announced proposal relating to its 6.5% sustainability-linked senior unsecured bonds due 2026 (the “NOK Bonds”) for certain amendments to the terms of the NOK Bonds related to the announcement by
the Company on November 1, 2022 that the Company will be acquired by Poseidon Acquisition Corp. (“Posiedon”) pursuant to the terms of a merger agreement (the “Amendment Proposal”). The vote of the holders of NOK Bonds with
respect to the Amendment Proposal, which was scheduled for December 16, 2022, has been cancelled. The NOK Bonds are indebtedness for which the Company is required, as a condition to the closing of the pending merger with Poseidon, to either obtain
lender consent, clearance, authorization or approval or alternatively repay, redeem or otherwise retire such indebtedness in accordance with the terms of the merger agreement with Poseidon, unless Poseidon otherwise agrees. The Company is currently
reviewing different options with respect to the NOK Bonds.
