ATHENS, GREECE, December 4, 2023: Reference is made to the stock exchange announcement made by Okeanis Eco Tankers Corp. (“OET” or the “Company”) on November 2, 2023 (the “Announcement”), regarding the Company’s public filing of a registration statement with the U.S. Securities and Exchange Commission (“SEC”) to list its common shares on the New York Stock Exchange (“NYSE”).

The U.S. regulatory review process has concluded. Following this, the Company has filed an acceleration request asking the SEC to declare its registration statement effective on December 6, 2023. First day of listing on NYSE is expected to be on or about December 11, 2023. The Company’s registration statement on Form 20-F is available on www.sec.gov.

TRADING SUSPENSION

As detailed in the Announcement, and due to technical settlement procedures in the VPS, a trading suspension in the Company’s common shares on Oslo Bors will be required for a period expected to be at least two trading days (the “Trading Suspension”) in connection with the changes to the Company’s share registration structure (described as “Share Registration Conversion” in the Announcement). The Company will make a request to Oslo Bors to approve the Trading Suspension prior to implementation of the Share Registration Conversion.

During the Trading Suspension, the Company’s common shares will be temporarily suspended from trading on Oslo Bors. From the perspective of an investor holding the Company’s common shares in the VPS, the last settlement cycle for common shares traded prior to the Trading Suspension is expected to take place on December 8, 2023. Investors trading in the Company’s common shares prior to start of the Trading Suspension should not agree to settlement periods that would provide for settlement after the expected last day of the Trading Suspension, being December 8, 2023. Any such trades are expected to be cancelled.

Following completion of the Share Registration Conversion, the Trading Suspension will end, and the Company’s common shares will resume trading as normal.

Below are the expected key dates in connection with the Trading Suspension:

– December 6, 2023: Last day of trading in the Company’s common shares on Oslo Bors prior to the Trading Suspension. All trades done on December 6, 2023 must be executed with regular settlement T+2 or shorter.

– December 7, 2023: First trading day of the Trading Suspension in the Company’s common shares on Oslo Bors.

– December 8, 2023: Second trading day of the Trading Suspension in the Company’s common shares on Oslo Bors. The Share Registration Conversion is expected to be completed after Oslo Bors opening hours.

– December 11, 2023: Expected end of the Trading Suspension and the Company’s common shares will resume normal trading from start of trading on Oslo Bors with the same ticker code of “OET”. Expected first day of trading in the Company’s common shares on NYSE with the ticker code of “ECO”.

The Company will confirm the dates for the expected Trading Suspension in a separate announcement.

No action will be required by an investor holding common shares in the VPS in connection with the Share Registration Conversion and investors’ registered holdings in the VPS will continue.

In conjunction with the listing on NYSE, the Company’s ticker on Oslo Bors is to remain “OET”. The Company’s common shares will continue to trade under the same ISIN as today (MHY641771016).
