Ålesund, 17 April 2026

Reference is made to the stock exchange announcement published by Golden Energy Offshore Services ASA (the “Company”) on 9 April 2026 regarding the launch of a subsequent offering of up to 5,625,000 new shares in the Company, each with a par value of NOK 8.00 (the “Offer Shares”), at a fixed subscription price of NOK 8.00 per Offer Share (the “Subsequent Offering”) and the Company’s announcement published on 10 April 2026 regarding commencement of the subscription period in the Subsequent Offering.

cThe subscription period for the Subsequent Offering expired today, 17 April 2026, at 16:30 (CEST). The Company has received valid subscriptions for more than 5,625,000 Offer Shares. Hence, the Company will, subject to timely payment, issue 5,625,000 Offer Shares, each with a par value of NOK 8.00, thereby increasing the Company's share capital by NOK 45,000,000, in accordance with the allocation principles set out in the Company's prospectus dated 7 April 2026 (the "Prospectus"). The Company will consequently receive gross proceeds of approx. NOK 45,000,000.

Notifications of allocated Offer Shares and the corresponding subscription amount to be paid by each subscriber is expected to be available on or about 20 April 2026. Subscribers having access to investor services through their account manager in Euronext Securities Oslo ("VPS") will be able to check the number of Offer Shares allocated to them from 10:30 CEST on or about 20 April 2026. Subscribers who do not have access to investor services through their VPS account manager may contact Pareto Securities AS (the “Manager”) from 10:30 CEST on the same date to obtain information about the number of Offer Shares allocated to them.

The subscription amount for payment by the subscribers for allocated Offer Shares falls due on 22 April 2026.

The Offer Shares may not be transferred or traded until they are fully paid and the share capital increase pertaining to the Subsequent Offering has been registered with the Norwegian Register of Business Enterprises (the "NRBE"). Subject to timely payment of the Offer Shares, the Company expects that the share capital increase will be registered with the NRBE on or about 28 April 2026 and that the Offer Shares will commence trading on Euronext Growth Oslo on or about 29 April 2026. A separate announcement will be made when the share capital increase has been registered with the NRBE. The Offer Shares will rank pari passu in all respects with the Company's existing shares and will carry full shareholder rights from the time of such registration.

Additional information regarding the Subsequent Offering, including procedures for payment and delivery of the Offer Shares, is set out in the Prospectus, which, subject to regulatory restrictions in certain jurisdictions, is available at the Manager’s website: www.paretosec.com/transactions.

Pareto Securities AS is acting as manager in the Subsequent Offering. Advokatfirmaet BAHR AS is acting as legal advisor to the Company.
