EXPLANATORY NOTE

Reorganization

This Post-Effective Amendment No. 3 (“Post-Effective Amendment No. 3”) to the Registration Statement on Form F-3, File No. 333-195571, as amended (the “Registration Statement”), is being filed pursuant to Rule 414 under the Securities Act of 1933, as amended (the “Securities Act”), by Atlas Corp., a Republic of the Marshall Islands corporation (“Atlas” or the “Registrant”), as the successor registrant to Seaspan Corporation, a Republic of the Marshall Islands corporation and the former publicly-traded parent of Atlas (the “Predecessor”).

On February 27, 2020, in connection with the transactions contemplated by the Agreement and Plan of Merger, dated as of November 20, 2019, as amended, by and among the Registrant, the Predecessor and Seaspan Holdco V Ltd., a Republic of the Marshall Islands corporation and a wholly owned subsidiary of Atlas (“Merger Sub”), the Predecessor effected a holding company reorganization, in which Atlas became the parent company of the Predecessor (the “Reorganization”). To effect the Reorganization, the Predecessor formed Atlas and in turn caused Atlas to form Merger Sub. The Reorganization was implemented by merging Merger Sub with and into the Predecessor, with the Predecessor surviving as a wholly owned subsidiary of Atlas and, by virtue of the Reorganization, each issued and outstanding Class A common share, par value $0.01 per share (“Class A common share”), of the Predecessor was cancelled, and Atlas issued, in respect of each canceled Class A common share of the Predecessor, one common share, par value $0.01 per share (“common share”), of Atlas to the holder of such canceled Class A common share.

Legal Matters

In connection with the filing of this Post-Effective Amendment No. 3, the validity of common shares and certain other legal matters with respect to the laws of the Republic of the Marshall Islands will be passed upon for Atlas by Dennis J. Reeder, Reeder & Simpson, P.C. Certain other legal matters will be passed upon for Atlas by Blank Rome LLP, New York, New York, by Blake, Cassels & Graydon LLP, Vancouver, British Columbia, and by Osborne Clarke LLP, London, United Kingdom, in connection with the filing of this Post-Effective Amendment No. 3. Blank Rome LLP, Blake, Cassels & Graydon LLP and Osborne Clarke LLP may rely on the opinions of Dennis J. Reeder, Reeder & Simpson, P.C. for all matters of the Republic of the Marshall Islands law.

Successor Issuer

Following the Reorganization, Atlas is the successor issuer of the Predecessor pursuant to Rule 414 under the Securities Act and Rule 12g-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

In accordance with Rule 414(d) under the Securities Act, Atlas, as the successor issuer to the Predecessor, hereby expressly adopts the Registration Statement as its own registration statement (except as specifically modified by this Post-Effective Amendment No. 3) for all purposes of the Securities Act and the Exchange Act, as updated by subsequent filings under the Exchange Act.

Accordingly, Part I has been omitted from this Post-Effective Amendment No. 3.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 8. Indemnification of Directors and Officers

The Republic of the Marshall Islands Business Corporations Act (the “BCA”) authorizes corporations to limit or eliminate the personal liability of directors to corporations and their shareholders for monetary damages for breaches of directors’ fiduciary duties. Atlas articles of incorporation include a provision that provides that, to the fullest extent permitted by law, a director of Atlas shall not be personally liable to Atlas or its shareholders for monetary damages for breach of fiduciary duty as a director.

Atlas articles of incorporation provide that it must indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, including in an action by or in the right of Atlas, by reason of the fact he or she is or was a director or officer of Atlas or is or was serving, at the request of Atlas, as a director or officer of another corporation, partnership, joint venture, trust or other enterprise (the “Indemnitee”) against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or proceeding, unless a final and unappealable determination by a court of competent jurisdiction has been made that he or she did not act in good faith or in a manner he or she did not reasonably believe to be in or not opposed to the best interest of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful. Atlas articles of incorporation further provide that the purpose of the provisions set forth in the articles of incorporation is to fully indemnify the Indemnitee to the fullest extent permitted by Section 60 of the BCA or any successor statute.

Atlas is also expressly authorized to (i) advance expenses to its directors and offices in advance of the final disposition of any proceeding upon receipt of an undertaking to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified under the provisions of Atlas articles of incorporation, and (ii) purchase and maintain insurance on behalf of any person who is or was a director of officer of Atlas or serving in such capacity in another corporation at the request of Atlas against any liability asserted against such person and incurred by such person in such capacity whether or not Atlas would have the power to indemnify such person against such liability by law or under the provisions of Atlas articles of incorporation. Atlas articles of incorporation further provide that the purpose of the provisions set forth in the articles of incorporation is to advance funds to the fullest extent permitted by Section 60 of the BCA or any successor statute.

The directors and officers of Atlas also may be indemnified against liability they may incur for serving in those capacities pursuant to liability insurance policies maintained by and indemnification arrangements with Atlas. In addition, Atlas intends to enter into separate indemnification agreements with some of its officers and directors.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling Atlas pursuant to the foregoing provisions, Atlas has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Any underwriting agreement that has been or will be filed as an exhibit hereto or incorporated by reference herein contains or will contain provisions whereby the underwriter or underwriters agree to indemnify Atlas, its directors and certain officers and other persons against certain claims.

Item 10. Undertakings

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a) (3) of the Securities Act need not be furnished, provided that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act or Rule 3-19 if such financial statements and information are contained in periodic reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or 15(d) of the Exchange Act that are incorporated by reference in the Form F-3.

(5) That, for the purpose of determining liability under the Securities Act to any purchaser:

(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(6) That, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(7) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
