Exhibit 99.1

AMENDED AND RESTATED STOCK INCENTIVE PLAN

On February 27, 2020 (the “Transaction Date”), Seaspan Corporation (“Seaspan”) completed its holding company reorganization (the “Reorganization”). The Reorganization was effected pursuant to the Agreement and Plan of Merger, dated as of November 20, 2019, as amended (the “Merger Agreement”), by and among Seaspan, Atlas Corp., a wholly owned subsidiary of Seaspan (“Atlas” or the “Company”), and Seaspan Holdco V Ltd., a wholly owned subsidiary of Atlas (“Merger Sub”). Under the terms of the Merger Agreement, at the effective time of the Merger, Merger Sub merged with and into Seaspan (the “Merger”), and the separate corporate existence of Merger Sub ceased, with Seaspan continuing as the surviving corporation in the Merger and a direct, wholly owned subsidiary of Atlas. In connection with the Reorganization, all outstanding Seaspan common shares were canceled, and Atlas issued, in respect of each canceled Seaspan common share, one common share of Atlas (“common share”) to the holder of such canceled Seaspan common share.

As of the Transaction Date, responsibility for the Seaspan Stock Incentive Plan (the “Plan”), including administration of the Plan, was assumed by Atlas, and common shares of Atlas will be issued to participants in the Plan in connection with all awards granted under the Plan outstanding as of the Transaction Date. The term “Plan” also refers to the Amended and Restated Stock Incentive Plan, as assumed by Atlas in connection with the Reorganization.

The Committee may impose such limitations and restrictions, in addition to any required restrictions/limitations, as the Committee may determine in its sole discretion. Any grant made pursuant to such a delegation shall be subject to all of the provisions of the Plan concerning this type of Award.

SECTION 4. Shares Available for Awards.

Effective June 29, 2020, subject to adjustment as provided in paragraph (c) below, the number of Shares that may be issued with respect to Awards granted under the Plan shall be equal to (i) 5,000,000 plus (ii) an additional number of Shares equal to 5,000,000. If an Award is forfeited or otherwise lapses, expires, terminates or is canceled without the actual delivery of Shares or is settled in cash, then the Shares covered by such Award, to the extent of such forfeiture, expiration, lapse, termination, cancellation or cash settlement, shall again be Shares that may be issued with respect to Awards granted under the Plan. Shares tendered to or withheld by the Company to satisfy its tax withholding obligations or the exercise price shall be available for issuance under future Awards, subject to the overall limitation provided in the first sentence above.

(b) Sources of Shares Deliverable Under Awards. Any Shares delivered pursuant to an Award may consist, in whole or in part, of authorized and unissued Shares or of treasury Shares.

(c) Adjustments. In the event of a stock dividend or stock split with respect to Shares, the number of Shares with respect to which Awards may be granted, the number of Shares subject to outstanding Awards and the grant or exercise price with respect to outstanding Awards automatically shall be proportionately adjusted, without action by the Committee; provided, however, such automatic adjustment shall be evidenced by written addendums to the Plan and Award Agreements prepared by the Company and, with respect to Options, shall be in accordance with the Treasury Regulations concerning Incentive Stock Options. Further, in the event that the Committee determines that any distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, reorganization, merger, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other similar corporate transaction or event affects the Shares such that an adjustment is determined by the Committee to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, then the Committee shall, in such manner as it may deem equitable, adjust any or all of (i) the number and type of Shares (or other securities or property) with respect to which Awards may be granted, (ii) the number and type of Shares (or

other securities or property) subject to outstanding Awards, and (iii) the grant or exercise price with respect to any Award or, if deemed appropriate, make provision for a cash payment to the holder of an outstanding Award; provided that the number of Shares subject to any Award denominated in Shares shall always be a whole number.

SECTION 5. Eligibility.

Any Employee, Consultant or Director shall be eligible to be designated a Participant by the Committee. No individual shall have any right to be granted an Award pursuant to this Plan.

SECTION 6. Awards.

(a) Options. Subject to the provisions of the Plan, the Committee shall have the authority to determine Participants to whom Options shall be granted, the number of Shares to be covered by each Option, the purchase price therefor and the conditions and limitations applicable to the exercise of the Option, including the following terms and conditions and such additional terms and conditions, as the Committee shall determine, that are not inconsistent with the provisions of the Plan. An Option may not be granted only to those Persons with respect to whom, for purposes of Section 409A, the Shares are “stock of the service recipient.”

(1) Exercise Price. The purchase price per Share purchasable under an Option shall be determined by the Committee at the time the Option is granted, but shall not be less than the Fair Market Value per Share on the effective date of such grant.

(2) Time and Method of Exercise. The Committee shall determine and provide in the Award Agreement or by action subsequent to the grant the time or times at which an Option may be exercised in whole or in part, and the method or methods by which, and the form or forms (which may include, without limitation, cash, check acceptable to the Company, Shares already-owned, Shares issuable upon Option exercise, a “cashless-broker” exercise (through procedures approved by the Committee), or any combination thereof, having a Fair Market Value on the exercise date equal to the relevant exercise price) in which payment of the exercise price and tax withholding obligation with respect thereto may be made or deemed to have been made. The Committee shall also determine the performance or other conditions, if any, that must be satisfied before all or part of an Option may vest and be exercised. No portion of an Option which is unexercisable at termination of the Participant’s employment or service, as applicable, shall thereafter become exercisable, except as may be otherwise provided by the Committee either in the Award Agreement or by action following the grant of the Option.

(b) Restricted Stock. Subject to the provisions of the Plan, the Committee shall have the authority to determine the Participants to whom Restricted Stock shall be granted, the number of Shares of Restricted Stock to be granted to each such Participant, the duration of the Restricted Period during which, and the conditions or other criteria, including the passage of time, under which the Restricted Stock may vest or be forfeited to the Company, and the other terms and conditions of such Awards, if any.

(1) Dividends. Dividends paid on Restricted Stock may be paid directly to the Participant, may be subject to risk of forfeiture and/or transfer restrictions during any period established by the Committee or sequestered and held in a bookkeeping cash account (with or without interest) or reinvested on an immediate or deferred basis in additional shares of Common Stock, which credit or shares may be subject to the same restrictions as the underlying Award or such other restrictions, all as determined by the Committee in its discretion, as provided in the Award Agreement.

(2) Registration. Any Restricted Stock may be evidenced in such manner as the Committee shall deem appropriate, including, without limitation, book-entry registration or issuance of a stock certificate or certificates. In the event any stock certificate is issued in respect of Restricted Stock granted under the Plan, such certificate shall be registered in the name of the Participant and shall bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Restricted Stock.

(3) Forfeiture and Restrictions Lapse. Except as otherwise determined by the Committee or the terms of the Award Agreement, upon a Participant’s termination of employment or service (as determined under criteria established by the Committee) for any reason during the applicable Restricted Period, all Restricted Stock shall be forfeited by the Participant and re-acquired by the Company. The Committee may waive in whole or in part any or all remaining restrictions with respect to such Participant’s Restricted Stock. Unrestricted Shares, evidenced in such manner as the Committee shall deem appropriate, shall be issued to the holder of Restricted Stock promptly after the applicable restrictions have lapsed or otherwise been satisfied.

(4) Restrictions. Restricted Stock shall be subject to such restrictions on transferability and other restrictions as the Committee may impose (including, without limitation, restrictions on the right to vote Restricted Stock or the right to receive dividends on the Restricted Stock). These restrictions may lapse separately or in combination at such times, pursuant to such circumstances, in such installments, or otherwise, as the Committee determines at the time of the grant of the Award or thereafter. During the Restricted Period, Restricted Stock will be subject to such limitations on transfer as necessary to comply with Section 83 of the Code.

(c) Phantom Shares. The Committee shall have the authority to grant Awards of Phantom Shares to Participants upon such terms and conditions as the Committee may determine.

(1) Terms and Conditions. Each Phantom Share Award shall constitute an agreement by the Company to issue or transfer a specified number of Shares or pay an amount of cash equal to the Fair Market Value of a specified number of Shares, or a combination thereof to the Participant in the future, subject to the fulfillment during the Restricted Period of such conditions, including the passage of time, if any, as the Committee may specify at the date of grant. During the Restricted Period, the Participant shall not have any rights of ownership in the Phantom Shares and shall not have any right to vote such shares.

(2) Dividend Equivalents. Any Phantom Share award may provide, in the discretion of the Committee, that any or all dividends or other distributions paid on Shares during the Restricted Period be credited in a cash bookkeeping account (with or without interest) or that equivalent additional Phantom Shares be awarded, which account or Phantom Shares may be subject to the same restrictions as the underlying Award or such other restrictions as the Committee may determine.

(3) Forfeiture and Restrictions Lapse. Except as otherwise determined by the Committee or set forth in the Award Agreement, upon a Participant’s termination of employment or service (as determined under criteria established by the Committee) for any reason during the applicable Restricted Period, all Phantom Shares shall be forfeited by the Participant. The Committee may waive in whole or in part any or all remaining restrictions with respect to such Participant’s Phantom Shares.

(4) Payment of Phantom Shares. Phantom Shares shall be paid in cash and/or in Shares, in the sole discretion of the Committee, in a lump sum following the close of the Restricted Period.

(d) Other Stock-Based Awards. The Committee may grant to Participants an Other Stock-Based Award, which shall consist of an Award denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, Shares. Subject to the terms of the Plan, the Committee shall determine the terms and conditions of any such Other Stock-Based Award. An Other Stock-Based Award may be paid in cash, Shares or any combination thereof in the discretion of the Committee.

(e) General.

(1) Awards May Be Granted Separately or Together. Awards may, in the discretion of the Committee, be granted either alone or in addition to, in tandem with, any other Award granted under the Plan or any award granted under any other plan of the Company or any Subsidiary. Awards granted in addition to or in tandem with other Awards or awards granted under any other plan may be granted either at the same time as or at a different time from the grant of such other Awards or awards.

(2) Limits on Transfer of Awards.

(A) Except as provided in paragraph (C) below, each Award, and each right under any Award, shall be exercisable only by the Participant during the Participant’s lifetime, or if permissible under applicable law, by the Participant’s guardian or legal representative as determined by the Committee.

(B) Except as provided in paragraph (C) below, no Award and no right under any such Award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant otherwise than by will or by the laws of descent and distribution, and any such purported prohibited assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or any Subsidiary.

(C) To the extent specifically approved in writing by the Committee, an Award may be transferred to immediate family members or related family trusts, limited partnerships or similar entities on such terms and conditions as the Committee may establish or approve.

(3) Terms of Awards. The term of each Award shall be for such period as may be determined by the Committee; provided, that in no event shall the term of any Award exceed a period of 10 years from the date of its grant.

(4) Share Certificate. All certificates for Shares or other securities of the Company or any Subsidiary delivered under the Plan pursuant to any Award or the exercise thereof shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan or the rules, regulations, and other requirements of the SEC, any stock exchange upon which such Shares or other securities are then listed, and any applicable federal or state laws, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.

(5) Consideration for Grants. Awards may be granted for no cash consideration or for such consideration as the Committee determines including, without limitation, such minimal cash consideration as may be required by applicable law.

(6) Delivery of Shares or other Securities and Payment by Participant of Consideration. No Shares or other securities shall be delivered pursuant to any Award until payment in full of any amount required to be paid pursuant to the Plan or the applicable Award Agreement (including, without limitation, any exercise price or tax withholding) is received by the Company. Such payment may be made by such method or methods and in such form or forms as the Committee shall determine, including, without limitation, cash, Shares, other securities, other Awards or other property, withholding of Shares, cashless exercise with simultaneous sale, or any combination thereof, provided that the combined value, as determined by the Committee, of all cash and cash equivalents and the Fair Market Value of any such Shares or other property so tendered to the Company, as of the date of such tender, is at least equal to the full amount required to be paid pursuant to the plan or the applicable Award Agreement to the Company.

SECTION 7. Amendment and Termination.

Except to the extent prohibited by applicable law and unless otherwise expressly provided in an Award Agreement or in the Plan:

(2) Amendments to Awards. The Committee may waive any conditions or rights under, amend any terms of, or alter any Award theretofore granted, provided no change in any Award shall materially adversely affect the rights of a Participant under the Award without the consent of such Participant.

SECTION 8. General Provisions.

(a) No Rights to Awards. No Participant or other Person shall have any claim to be granted any Award, there is no obligation for uniformity of treatment of Participants, or holders or beneficiaries of Awards and the terms and conditions of Awards need not be the same with respect to each recipient.

(b) Tax Withholding. The Company or any Affiliate is authorized to withhold from any Award, from any payment due or transfer made under any Award or from any compensation or other amount owing to a Participant the amount (in cash, Shares, or other property) of any taxes required to be withheld by the Company or Affiliate in respect of the Award, its exercise, the lapse of restrictions thereon, or any payment or transfer under the Award and to take such other action as may be necessary in the opinion of the Company to satisfy all of its obligations for the payment of such taxes. In addition, the Committee may provide, in an Award Agreement, that the Participant may direct the Company to satisfy such Participant’s tax withholding obligations through the withholding of Shares otherwise to be acquired upon the exercise or payment of such Award.

(c) No Right to Employment or Retention. The grant of an Award shall not be construed as giving a Participant the right to be retained in the employ of the Company or any Affiliate or under any other service contract with the Company or any Affiliate, or to remain on the Board. Further, the Company or an Affiliate may at any time dismiss a Participant from employment or terminate any contractual agreement or relationship with any Consultant, free from any liability or any claim under the Plan, with or without cause, unless otherwise expressly provided in the Plan, in any Award Agreement or any other agreement or contract between the Company or an Affiliate and the affected Participant. If a Participant’s employer ceases to be an Affiliate, such Participant shall be deemed to have terminated employment for purposes of the Plan, unless specifically provided otherwise in the Award Agreement.

(d) Change of Control, Unusual Transactions or Events. In the event of any distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, reorganization, merger, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or any corporate transaction, as defined in Treasury Regulations §1.424-1(a)(3), “change of ownership, or effective control of a corporation or change of ownership of a substantial portion of the assets of a corporation,” as defined in the Treasury Regulations under Section 409A of the Code, or event or any unusual or nonrecurring transactions or events affecting the Company, any affiliate of the Company, or the financial statements of the Company or any affiliate, or of changes in applicable laws, regulations or accounting principles, and whenever the Committee determines that action is appropriate in order to prevent the dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to any Award under the Plan, to facilitate such transactions or events or to give effect to such changes in laws, regulations or principles, the Committee, in its sole discretion and on such terms and conditions as it deems appropriate, either by amendment of the terms of any outstanding Awards or by action taken prior to the occurrence of such transaction or event and

either automatically or upon the Participant’s request, is hereby authorized to take any one or more of the following actions:

(1) To provide for either (A) termination of any such Award in exchange for an amount of cash, if any, equal to the amount that would have been attained upon the exercise of such Award or realization of the Participant’s rights (and, for the avoidance of doubt, if as of the date of the occurrence of the transaction or event described in this Section 8(d) the Committee determines in good faith that no amount would have been attained upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the Company without payment) or (B) the replacement of such Award with other rights or property selected by the Committee in its sole discretion;

(2) To provide that such Award be assumed by the successor or survivor corporation, or a parent or subsidiary thereof, or shall be substituted for by similar options, rights or awards covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and prices; and

(3) To make adjustments in the number and type of Shares (or other securities or property) subject to outstanding Awards, and in the number and kind of outstanding Awards and/or in the terms and conditions of (including the grant or exercise price), and the criteria included in, outstanding Awards and Awards which may be granted in the future;

(4) To provide that such Award shall be exercisable or payable or fully vested with respect to all shares covered thereby, notwithstanding anything to the contrary in the Plan or the applicable Award Agreement; and

(5) To provide that the Award cannot vest, be exercised or become payable after such event.

(e) Governing Law. The validity, construction, and effect of the Plan and any rules and regulations relating to the Plan shall be determined in accordance with the laws of New York and applicable U.S. federal law.

(f) Severability. If any provision of the Plan or any Award is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any Person or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to the applicable laws, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be stricken as to such jurisdiction, Person or Award and the remainder of the Plan and any such Award shall remain in full force and effect.

(g) Other Laws. The Committee may refuse to issue or transfer any Shares or other consideration under an Award, permit the exercise of an Award and/or the satisfaction of its tax withholding obligation in the manner elected by the Participant, holder or beneficiary if, acting in its sole discretion, it determines that the issuance of transfer or such Shares or such other consideration, the manner of exercise or satisfaction of the tax withholding obligation might violate any applicable law or regulation.

(h) No Trust or Fund Created. Neither the Plan nor the Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any Affiliate and a Participant or any other Person. To the extent that any Person acquires a right to receive payments from the Company or any Affiliate pursuant to an Award, such right shall be no greater than the right of any general unsecured creditor of the Company or any Subsidiary.

(i) No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to the Plan or any Award, and the Committee shall determine whether cash, other securities, or other property shall be paid or transferred in lieu of any fractional Shares or whether such fractional Shares or any rights thereto shall be cancelled, terminated, or otherwise eliminated.

(j) Headings. Headings are given to the Section and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the plan or any provision thereof.

SECTION 9. Compliance with Section 409A. Nothing in the Plan or any Award Agreement shall operate or be construed to cause the Plan or an Award to fail to comply with the requirements of Section 409A of the Internal Revenue Code. With respect to an Award that is subject to Section 409A of the Code, notwithstanding anything in the Plan or the Award Agreement to the contrary,

(1) payment under the Plan may not be made earlier than as permitted by Section 409A(a)(2) of the Code, i.e., a separation from service, death, a specified time (or fixed schedule) specified at the date of the deferral, a “change in ownership, control or effective control, as provided in regulations or other guidance under Section 409A”, or the occurrence of an unforeseen event;

(2) the time or schedule of any payment under the Plan may not be accelerated except as provided in regulations or guidance issued under Section 409A;

(3) no elections may be made by a Participant to defer compensation under the Plan; and

(4) no elections may be made by a Participant to change the time and form of payment under the Plan.
