NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

JUNE 8, 2026

To the Stockholders of International Seaways, Inc.:

We cordially invite you to attend the Annual Meeting of Stockholders (the“Annual Meeting”) of International Seaways, Inc. (the“Company” or“INSW”), to be held at Club 101, Kenilworth Room, 101 Park Avenue, New York, New York, on Monday, June 8, 2026, at 2:00 p.m. Eastern time. You will also be able to attend the meeting online, vote your shares and submit questions during the meeting by visiting the websitewww.virtualshareholdermeeting.com/INSW2026. In order to join the Annual Meeting virtually, you will need to have the 16-digit control number included on your proxy card or in the instructions that accompanied your proxy materials (or in other communications you may have received from the broker, bank or other nominee in whose name your shares are held). The Annual Meeting will be held for the following purposes:

We will also act on any other business that is properly raised in accordance with the Company’s by-laws.

Only stockholders of record at the close of business on April 9, 2026 (the “Record Date”) are entitled to notice of, and to vote at, the Annual Meeting. The stockholders list will be open to the examination of stockholders for any purpose germane to the Annual Meeting during normal business hours for ten days prior to the Annual Meeting, at the Company’s offices, 600 Third Avenue, 39 th Floor, New York, New York.

Your vote is important so that your shares are represented at the Annual Meeting. We urge you to vote as soon as possible by telephone, over the Internet or by marking, signing and returning by mail your proxy or voting instruction card, even if you plan to attend the Annual Meeting in person or virtually. If you attend the meeting and wish to vote, you may withdraw your proxy and vote at that time. Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to vote at the meeting, you must obtain a proxy issued in your name from that record holder. Your prompt consideration is greatly appreciated.

The U.S. Securities and Exchange Commission (the “SEC”) rules allows issuers, including us, to furnish certain proxy materials to their stockholders over the Internet. These rules lower delivery costs and reduce the environmental impact of our Annual Meeting, while allowing us to provide stockholders with the information they need. If you requested a printed copy of these materials, we have included a copy of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 (with this notice and the accompanying Proxy Statement, the “2025 Annual Report”).

By order of the Board of Directors,

JAMES D. SMALL III

Chief Administrative Officer, Senior Vice President,

General Counsel and Secretary

New York, New York
