Dolphin Drilling AS: Key information related to the potential subsequent offering

NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, IN WHOLE OR IN PART DIRECTLY OR INDIRECTLY, IN AUSTRALIA, CANADA, JAPAN, HONG KONG, SOUTH AFRICA OR THE UNITED STATES OR ANY OTHER JURISDICTION IN WHICH THE RELEASE, PUBLICATION OR DISTRIBUTION WOULD BE UNLAWFUL. THIS ANNOUNCEMENT DOES NOT CONSTITUTE AN OFFER OF ANY OF THE SECURITIES DESCRIBED HEREIN.

(Oslo, 23 June 2023) Reference is made to the stock exchange announcement made by Dolphin Drilling AS ("Dolphin Drilling" or the "Company") on 22 June 2023 regarding the successful completion of a private placement of 84,471,200 new shares in the Company , each with a par value of NOK 10, at a subscription price of NOK 7.50 per share (the "Subscription Price"), raising gross proceeds of NOK 633,534,000 (the "Private Placement"), and a potential subsequent offering of up to 11,100,000 new shares, each with a par value of NOK 10 (to be adjusted to NOK 1 per share following completion of the share capital reduction), (the "Subsequent Offering Shares") at the Subscription Price (the "Subsequent Offering").

The Company has resolved to carry out the Subsequent Offering. The Subsequent Offering will consist of up to 11,100,000 Subsequent Offering Shares which, subject to applicable securities law, will be directed towards existing eligible shareholders in the Company as of 22 June 2023 (as registered in the VPS two trading days thereafter) (the "Record Date")) who (i) were not included in the wall-crossing phase of the Private Placement, (ii) were not allocated Shares in the Private Placement, and (iii) are not resident in a jurisdiction where such offering would be unlawful, or would (in jurisdictions other than Norway) require any prospectus filing, registration or similar action.

Completion of the Subsequent Offering will, inter alia, be subject to (i) all relevant corporate resolutions being made, including approval by the EGM; (ii) prevailing market price of the Company's shares, including the price of the Company's shares not trading below the offer price in the Subsequent Offering over a period with sufficient liquidity, (iii) completion of the share capital reduction and (iv) the publication of an offering prospectus. The subscription period for the Subsequent Offering is expected to commence as soon as possible following the fulfilment of the conditions set out above.

Whether or not the Subsequent Offering will ultimately take place, will depend inter alia on the development of the price of the shares in the Company after completion of the Private Placement. The Subsequent Offering may be cancelled or discontinued at the discretion of the Company, in cooperation with the Managers, if the shares of the Company trade at or below the Subscription Price at meaningful volumes, which will imply that eligible shareholders have had the opportunity to limit dilution by acquiring listed shares in the secondary market at price levels at or below the Subscription Price.

In accordance with the continuing obligations of companies listed on Euronext Growth Oslo, the following key information is given with respect to the Subsequent Offering:

• Date on which the terms and conditions of the repair issue were announced: 22 June 2023
• Last day including right: 22 June 2023
• Ex-date: 23 June 2023
