(Oslo, 29 August 2023) Reference is made to the stock exchange announcement published by Dolphin Drilling AS (the "Company") (ticker: DDRIL) on 22 June 2023 regarding the successful private placement of 84,471,200 new shares in the Company (the "Private Placement") and the contemplated subsequent offering (the "Subsequent Offering") of up to 11,100,000 new shares in the Company (the "Offer Shares") at a subscription price of NOK 7.50 per share (the "Subscription Price").

Reference is also made to the stock exchange announcement made on 30 June 2023 where the Company announced that the extraordinary general meeting (the "EGM") had resolved to grant the board of directors (the "Board") an authorization to increase the Company's share capital by up to NOK 111,000,000 in connection with the Subsequent Offering (as reduced to NOK 11,100,000 in connection with the completion of the share capital reduction).

The Company has submitted a national prospectus dated 28 August 2023 (the "Prospectus") for registration with the Norwegian Register of Business Enterprises ("NRBE") in accordance with section 7-8 of the Norwegian Securities Trading Act. Neither the Financial Supervisory Authority of Norway nor any other public authority has carried out any form of review, control, or approval of the Prospectus. This Prospectus does not constitute an EEA-prospectus.

The Prospectus will be made available electronically at the following websites: www.arctic.com/secno/en/transactions, https://securities.clarksons.com/Investment-Banking/Corporate-Finance/Transactions, www.dnb.no/emisjoner, https://transaksjoner.fearnleysecurities.com or www.paretosec.com/updates/transactions prior to the commencement of the Subscription Period (as defined below), expected on or about 30 August 2023.

The Subsequent Offering:

The Subsequent Offering comprises the offer of up to 11,100,000 Offer Shares in the Company, each with a nominal value of NOK 1.00, at a subscription price of NOK 7.50 per share, with gross proceeds of up to approximately NOK 83 million.

The Subsequent offering will, subject to applicable securities law, be directed towards shareholders in the Company as of 22 June 2023, as registered with the VPS on 26 June 2023 (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 offer would be illegal or would (in jurisdictions other than Norway) require the issuance of a prospectus, registration or other similar action (the ʺEligible Shareholdersʺ).

Each Eligible Shareholder will receive 0.567032 non-tradeable subscription rights (the "Subscription Rights") for each share held by such Eligible Shareholder in the Company as of the Record Date, rounded down to the nearest whole right. Each Subscription Right will, subject to applicable securities laws, give the preferential right to subscribe for, and be allocated, one (1) Offer Share in the Subsequent Offering. Over-subscription by Eligible Shareholders having received subscription rights will be permitted; however, there can be no assurance that Offer Shares will be allocated for such subscriptions. Subscription without subscription rights will not be permitted.

The subscription period for the Subsequent Offering will commence on 30 August 2023 at 09:00 (CEST) and will expire on 13 September 2023 at 16:30 (CEST) (the "Subscription Period").

In order to subscribe for shares, the Managers (as defined below) must receive a complete and duly signed subscription form or, in the case of online subscriptions, be registered by the expiry of the Subscription Period. Further instructions regarding the subscription procedure are available in the Prospectus. Subscriptions may only be made on the basis of the Prospectus. Subscription Rights that are not used to subscribe for Offer Shares before the expiry of the Subscription Period will have no value and will lapse without compensation to the holder.

The due date for payment of the Offer Shares is on or about 18 September 2023 (the "Payment Dateʺ). The Offer Shares will, after registration of the share capital increase in NRBE pertaining to the Offer Shares and when issued, be registered in the VPS in book-entry form and are expected to be delivered to the applicant's VPS account on or about 25 September 2023 subject to timely registration of the share capital increase with the Norwegian register of business enterprises.

Notifications of allocated Offer Shares and the corresponding subscription amount to be paid by each subscriber are expected to be distributed on or about 14 September 2023.

Trading in the Offer Shares on Euronext Growth Oslo is expected to commence on or about 25 September 2023, under the ticker code ʺDDRILʺ.

The completion of the Subsequent Offering is subject to (i) the Board resolving to approve the Subsequent Offering and issue the Offer Shares, (ii) duly payment of the Offer Shares by the subscribers, (iii) registration of the share capital increase pertaining to the Subsequent Offering with the NBRE, and (iv) issuance and delivery of the Offer Shares to the subscribers in the VPS.
