(Oslo, 23 May 2024) Reference is made to the stock exchange announcement made by Dolphin Drilling AS ("Dolphin Drilling" or the "Company") on 10 April 2024 regarding the successful private placement of 72,000,000 new shares in the Company at a subscription price of NOK 6 per share (the "Subscription Price"), raising gross proceeds of the NOK equivalent of USD 40 million (the "Private Placement"), and a potential subsequent offering of up to 10,000,000 new shares at the Subscription Price (the "Subsequent Offering").

Following the announcement of the completion of the Private Placement, the Company's shares have been traded below or at par level with the Subscription Price in the Private Placement in a total volume equivalent to a volume of shares representing more than the size of the intended Subsequent Offering. Accordingly, any shareholder wishing to neutralize the dilutive effect of the Private Placement has had sufficient opportunity (i.e. volume traded) to purchase shares in the market at prices at or below the Subscription Price, being the intended price per share in the Subsequent Offering. In light of the foregoing, the Company has today decided not to proceed with the Subsequent Offering.
