NOT FOR PUBLICATION, DISTRIBUTION OR RELEASE, IN WHOLE OR IN PART, DIRECTLY OR INDIRECTLY, IN OR INTO THE UNITED STATES OF AMERICA, AUSTRALIA, CANADA, THE HONG KONG SPECIAL ADMINISTRATIVE REGION OF THE PEOPLE'S REPUBLIC OF CHINA OR JAPAN, OR ANY OTHER JURISDICTION IN WHICH THE PUBLICATION, DISTRIBUTION OR RELEASE WOULD BE UNLAWFUL.

Athens, Greece, 17 March 2026: Reference is made to the announcements by Capital Tankers Corp. ("Capital Tankers" or the "Company") on 27 February 2026 regarding the successful private placement with a total transaction size of approx. NOK 4.8 billion (the "Private Placement") and the announcement on 17 March 2026 regarding the first day of trading in the Company's shares on Euronext Growth Oslo today, 17 March 2026 (the "Listing").

Pareto Securities AS (the "Stabilisation Manager") may, on behalf of the Managers (as defined below), engage in stabilisation activities in the Company's shares (the "Shares") from today (17 March 2026) to and including 15 April 2026 (the "Stabilisation Period"). Any stabilisation activities will be aimed at supporting the market price of the Shares.

In connection with the Private Placement, the Managers have over-allotted 4,650,000 Shares (the "Additional Shares") to applicants in the Private Placement, which equals approx. 15% of the new Shares allocated to applicants in the Private Placement (excluding the Additional Shares). In order to permit the delivery in respect of the over-allotments made, the Stabilisation Manager has, on behalf of the Managers, borrowed a number of existing Shares equal to the number of Additional Shares from Capital Maritime & Trading Corp. (the "Share Lender"), which will be redelivered to the Share Lender after expiry of the Stabilisation Period.

Further, the Company has granted the Stabilisation Manager, on behalf of the Managers, an option to require the Company to issue up to 4,650,000 new Shares in the Company (the "Greenshoe Option") at a price per share equal to the offer price in the Private Placement of NOK 134 (the "Offer Price"). The Stabilisation Manager may use the Greenshoe Option to close out short positions resulting from over-allotments made as part of the Private Placement and only to the extent such short positions have not been closed out by Shares purchased by the Stabilisation Manager when conducting stabilisation activities. The Greenshoe Option is exercisable, in whole or in part, by the Stabilisation Manager, on behalf of the Managers, during the Stabilisation Period.

The Stabilisation Manager may effect transactions with a view to support the market price of the Shares at a level higher than what might otherwise prevail, through buying Shares in the open market at prices equal to or lower than the Offer Price. There is no obligation on the Stabilisation Manager to conduct stabilisation activities and there is no assurance that stabilisation activities will be undertaken. Such stabilisation activities, if commenced, may be discontinued at any time, and will be brought to an end at the latest at the end of the Stabilisation Period.

Any net profit generated from any stabilisation activities conducted by the Stabilisation Manager during the Stabilisation Period shall be for the benefit of the Company.

If stabilisation activities are undertaken, the Company will publish information on the activities no later than seven trading days following such transaction(s). Further, within one week after the end of the Stabilisation Period, the Company will publish information as to whether or not stabilisation activities were undertaken. If stabilisation activities were undertaken, the statement will also include information about: (i) the total amount of Shares sold and purchased; (ii) the dates on which the Stabilisation Period began and ended; (iii) the price range between which stabilisation was carried out for each of the dates during which stabilisation was carried out; and (iv) the date at which stabilisation activities last occurred.

Any stabilisation activities will be conducted based on the principles set out in article 5 (4) of the EU Market Abuse Regulation (Regulation (EU) No 596/2014) and Chapter III of the supplemental rules set out in the Commission Delegated Regulation (EU) 2016/1052 with regard to regulatory technical standards for the conditions applicable to buy-back programmes and stabilisation measures.
