Information Contained in this Form 6-K Report

Issuance of 5.50% Blue Transition Senior Notes

On July 14, 2021, in connection with a previously announced private offering, Seaspan Corporation (“Seaspan”), a wholly owned subsidiary of Atlas Corp. (“Atlas”), issued $750.0 million aggregate principal amount of 5.50% Blue Transition Senior Notes due 2029 (the “Notes”). The Notes were sold to the Initial Purchasers (as defined below) in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), for resale by the Initial Purchasers to persons reasonably believed to be qualified institutional buyers (as defined in Rule 144A under the Securities Act) and to non-U.S. persons (as defined in Regulation S under the Securities Act) pursuant to the exemption from registration provided by Rule 144A and Regulation S under the Securities Act. In connection with the offering, Seaspan entered into a Purchase Agreement, dated July 9, 2021, with Citigroup Global Markets Inc. and Wells Fargo Securities, LLC, as representatives of the several initial purchasers named therein (the “Initial Purchasers”).

The net proceeds from the sale of the Notes were approximately $736.0 million, after deducting the Initial Purchasers’ discounts and commission and Seaspan’s estimated offering expenses. Seaspan intends to use the net proceeds to acquire, finance or refinance, in whole or in part, certain new and/or existing eligible projects consistent with Seaspan’s Blue Transition Bond Framework.

The Notes were issued pursuant to an Indenture dated as of July 14, 2021, by and between Seaspan and The Bank of New York Mellon, as trustee (the “Indenture”).

The Notes will be Seaspan’s senior unsecured obligations and will accrue interest payable semiannually in arrears on February 1 and August 1 of each year, beginning on February 1, 2022, at a rate of 5.50% per year. The Notes will not be guaranteed by Atlas or any of its or Seaspan’s respective subsidiaries. The Notes will mature on August 1, 2029, unless earlier exchanged, repurchased or redeemed.

Until August 1, 2024, Seaspan may redeem some or all of the Notes at a redemption price of 100% of their principal amount, plus accrued and unpaid interest, if any, to but excluding the redemption date, plus an applicable make-whole premium. At any time on or after August 1, 2024, Seaspan may redeem some or all of the notes at the redemption prices specified in the Indenture plus accrued and unpaid interest, if any, to but excluding the redemption date.

The Indenture contains covenants that limit, among other things, Seaspan’s ability and the ability of certain of its existing and future subsidiaries to: (i) pay dividends, make distributions, redeem capital stock and make certain other restricted payments of investments; (ii) incur additional indebtedness or issue certain equity interests; (iii) merge, consolidate or sell all or substantially all of its assets; (iv) issue or sell capital stock of some of its subsidiaries; (v) sell or exchange assets or enter into new businesses; (vi) create any restrictions on the payment of dividends, the making of distributions, the making of loans and the transfer of assets; (vii) create liens on assets; and (viii) enter into certain transactions with affiliates or related persons, subject to exceptions and qualifications.

The Indenture (including the form of Note included therein), is filed as Exhibit 4.1 hereto and is incorporated herein by reference.

The Notes have not been registered under the Securities Act or any state securities laws, and unless so registered, may not be offered or sold in the United States absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws. Accordingly, the Notes were offered and sold only to persons reasonably believed to be qualified institutional buyers (as defined in Rule 144A under the Securities Act) and to non-U.S. persons (as defined in Regulation S under the Securities Act).

This Report on Form 6-K does not constitute an offer to sell or a solicitation of an offer to buy, nor shall there be any offer or sale of, the Notes in any jurisdiction in which the offer, solicitation or sale of the Notes would be unlawful prior to the registration or qualification thereof under the securities laws of any such state or jurisdiction.
