November 2, 2023: Reference is made to the stock exchange announcement made by Okeanis Eco Tankers Corp. (“OET” or the “Company”) on November 2, 2023 regarding OET’s contemplated listing of its common shares on the New York Stock Exchange (“NYSE”).

Following an application from the Company, Oslo Bors, in its capacity as take-over supervisory authority in Norway, has resolved to exempt Okeanis Eco Tankers Corp. from all the provisions regulating voluntary and mandatory takeover offers in Chapter 6 of the Norwegian Securities Trading Act. The resolution by Oslo Bors is subject to, and shall take effect from, the listing of the Company’s common shares on NYSE and the simultaneous change from primary to secondary listing on Oslo Bors, which is expected to take place during mid-December 2023.
