DEREGISTRATION OF SECURITIES

This Post-Effective Amendment No. 1 to Form S-3 (the “Post-Effective Amendment”) relates to the Registration Statement on Form S-3 (File No. 333-237717) (the “Registration Statement”) filed with the Securities and Exchange Commission on April 16, 2020 by Diamond S Shipping Inc., a Republic of the Marshall Islands corporation (the “Registrant”). The Registration Statement pertains to the registration of an unspecified number of shares of common stock, shares of preferred stock, debt securities, warrants, rights, purchase contracts and units consisting of some or all of these securities in any combination, up to a maximum aggregate offering price of $500,000,000, by selling shareholders named therein.

On March 31, 2021, the Registrant, International Seaways, Inc., a Republic of the Marshall Islands corporation (“INSW”), and Dispatch Transaction Sub, Inc., a Republic of the Marshall Islands corporation and wholly-owned subsidiary of INSW (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which the Registrant and INSW have agreed, subject to the terms and conditions of the Merger Agreement, to effect a stock-for-stock merger of their respective businesses whereby Merger Sub will merge with and into the Registrant, resulting in the Registrant surviving the merger as a wholly owned subsidiary of INSW (the “Merger”).

As a result of the consummation of the transactions contemplated by the Merger Agreement, the Registrant has terminated all offerings of its securities pursuant to the Registration Statement. In accordance with undertakings made by the Registrant in the Registration Statement to remove from registration, by means of a post-effective amendment, any of the securities which remain unsold at the termination of the offerings, the Registrant hereby amends the Registration Statement to remove from registration the shares registered but unsold under the Registration Statement.
