Oslo, 15 April 2026: Reference is made to the previous stock exchange announcement made by Dolphin Drilling AS (the "Company") regarding a contemplated private placement (the "Private Placement") of new shares in the Company (the "Offer Shares").

The Company is pleased to announce that the Private Placement has been successfully placed. The Private Placement attracted strong investor demand, and in consultation with the Managers (as defined below), the Company therefore resolved to upsize the size of the Private Placement from the NOK equivalent of USD 50-55 million to the NOK equivalent of approximately USD 62.5 million, in order to accommodate for healthy allocations. The Company's board of directors (the "Board") has resolved to allocate 236,000,000 Offer Shares in the Private Placement (together the "Offer Shares") at a fixed subscription price of NOK 2.50 per Offer Share (the "Offer Price").

Arctic Securities AS, DNB Carnegie, a part of DNB Bank ASA and Fearnley Securities AS acted as joint bookrunners for the Private Placement (the "Managers").

Dolphin Drilling's Chairman, Ronny Bjørnådal, said: "Today's significantly oversubscribed equity raise represents a decisive turning point for Dolphin Drilling. With strong support from both existing and new shareholders, we have taken an important first step toward re-establishing Dolphin Drilling as a stronger offshore drilling company, underpinned by a significantly more robust balance sheet and solid liquidity position. This positions the Company with a powerful platform to pursue attractive strategic initiatives, as well as consolidation and growth opportunities."

Michael Boyd, Dolphin Drilling CEO, commented: "The company has set out the clear ambition to re-establish Dolphin Drilling as a stable, efficient, and investable platform capable for growth. To do that, we have strategic objectives focused on continuing to deliver safe and efficient operations, reducing structural cost, and targeting longer term earning visibility through contract backlog. Recent LOI awards announcing multi-year contracts indicate solid progress towards this, and today's announcement regarding the successful close of Company refinancing, with strong support from our main shareholder, provides the necessary financial runway."

As announced in the previous stock exchange announcement prior to the Private Placement, the Company and its subsidiaries entered into amendments to its existing credit facilities (the "Recapitalization Plan"), including to the USD 65 million loan facility of Dolphin Drilling Limited (the "Loan Facility Amendment") and the bond terms between Dolphin Drilling Offshore AS and Nordic Trustee (the "Nordic Bond Amendment"). As part of the Loan Facility Amendment, the existing lender has provided a USD 7.5 million bridge loan (the "Bridge Tranche").

The net proceeds from the Private Placement, will be used to repay the Bridge Tranche, fund reactivation costs for the "Borgland Dolphin" for the contract with Repsol, contract preparations, working capital expenses, and for general corporate purposes.

Mirabella Financial Services LLP, on behalf of Svelland Global Trading Master Fund and certain other accounts ("Svelland"), Starship Investments AS and Starship Norway AS (jointly referred to as "Starship"), had, subject to customary conditions, irrevocably undertaken to apply and subscribe for Offer Shares for an aggregate amount of the NOK equivalent of USD 15 million and USD 3 million, respectively, pursuant to pre-commitment undertakings. A pre-commitment fee equal to 10% of the pre-committed amount will be payable by the Company to each of Svelland and Starship in the form of a total of 6,796,584 new shares in the Company (the "Commission Shares") at a subscription price equal to the Offer Price. Svelland and Starship have been conditionally allocated their full pre-committed amounts in the Private Placement.

The issuance of Offer Shares and the Commission Shares will be subject to approval by an extraordinary general meeting of the Company expected to be held on or about 30 April 2026 (the "EGM").

Notifications of conditional allotment of Offer Shares are expected to be distributed to the applicants by the Managers on or about 16 April 2026.

The Offer Shares allocated in the Private Placement are expected to be settled on a delivery versus payment ("DvP") basis on or about 5 May 2026, subject to fulfilment of the Conditions (as defined below), including the necessary resolutions by the EGM. The allocated shares will be delivered to the
applicant's account in the Euronext Securities Oslo (the "VPS"). Delivery of Offer Shares on a DvP basis on the indicated timeline is expected to be facilitated through a pre-funding agreement to be entered into between the Company and the Managers (the "Pre-funding Agreement").

Completion of the Private Placement remains subject to: (A) the Company having confirmed in writing to the Managers that all conditions precedent for effectuation of the Loan Facility Amendment and Nordic Bond Amendment have been satisfied or will be satisfied upon completion of the Private Placement; (B) the EGM resolving to approve the Private Placement and issue the Offer Shares, as well as approval of ancillary resolutions necessary to consummate the Private Placement, including a share capital reduction to facilitate the subscription of Offer Shares and an authorisation to issue the Commission Shares; (C) registration of the share capital increase pertaining to issue of the Offer Shares in the Norwegian Register of Business Enterprises and the Offer Shares being validly issued and registered in the VPS; (D) the Pre-Funding Agreement remaining unmodified and in full force and effect pursuant to its terms and conditions, and (E) the Company having confirmed that (i) no bankruptcy proceedings have been opened by a court after petition for bankruptcy (Nw. konkursbegjæring) filed against the Company; (ii) the Company has not initiated voluntary winding-up proceedings (Nw. begjæring om oppbud); (iii) no application for reconstruction (Nw. rekonstruksjon) pursuant to the Norwegian Reconstruction Act has been filed in respect of the Company; and (iv) no notice of acceleration has occurred under any loan or credit facility to which the Company is a party. The conditions described above are jointly referred to as the "Conditions".

Following the necessary resolutions by the EGM and registrations of the issuance of the Offer Shares and the Commission Shares, the Company will have a share capital of NOK 1,005,094,858 divided into 402,037,943 shares, each with a nominal value of NOK 2.50.

Neither the Managers, the Company, nor any of their respective directors, officers, employees, representatives, or advisors, will be liable for any losses if the Private Placement is cancelled or modified, irrespective of the reason for such cancellation or modification.

Applicants who have been allocated Offer Shares in the Private Placement and who hold shares in the Company as of the date of the EGM have undertaken to vote in favour of, or give a voting proxy to be used in favour of, the resolutions proposed by the Board at the EGM to (i) decrease the share capital of the Company by reducing the nominal value of the shares of the Company to facilitate the subscription of Offer Shares, (ii) increase the share capital to issue the Offer Shares, and (iii) authorise the Board to issue the Commission Shares.

Equal treatment considerations

The Private Placement entails a deviation from the shareholders' pre-emptive rights pursuant to Sections 10-4 and 10-5 of the Norwegian Private Limited Companies Act. The Private Placement has been diligently considered by the Board in light of the principles of equal treatment of shareholders under the Norwegian Private Limited Companies Act, and the Board is of the opinion that it is in compliance with these principles.

In its assessment, the Board has inter alia emphasised that the Private Placement enables the Company to efficiently raise equity capital for the intended purpose and that the Private Placement was carried out at a premium compared to the closing price of the Company's shares as of 15 April 2026 and close to the volume weighted average price (VWAP) of the Company's shares over the past month. The Board also emphasised that the Private Placement is closely linked to the Recapitalization Plan and that the proposed structure has the necessary support from the Company's largest shareholder. Further, the Board has taken into consideration that the Private Placement and ancillary corporate resolutions are subject to approval by the EGM, at which the Company's shareholders will be given an opportunity to express their opinion and vote over the related share capital increases.

On the basis of the above, the Board has concluded to not carry out a subsequent offering.

Advisors

Arctic Securities AS, DNB Carnegie, a part of DNB Bank ASA, and Fearnley Securities AS are acting as joint bookrunners in the Private Placement.

Wikborg Rein Advokatfirma AS serves as legal counsel to the Company.
