Dolphin Drilling: Signs Multi-Year Contract for Borgland Dolphin

OSLO, Norway, 2 June 2026 - Dolphin Drilling AS (OSE: DDRIL) ("Dolphin") today announced the contract fixture of its semi-submersible drilling rig BORGLAND DOLPHIN with an undisclosed operator in the UK, which represents approximately USD 239 million in firm contract backlog, as referenced to in our announcement dated 14 April 2026 regarding a Letter of Intent.

The contract is scheduled to commence in the second half of 2027, in direct continuation following release of the Borgland Dolphin from its existing contract. The firm term runs through to the expiry of the rig's current Special Period Survey ("SPS") in October 2031 (inclusive of mobilisation and demobilisation). The contract includes options for up to a further 5-years, with a contribution to the SPS.

Chief Executive Officer, Michael Boyd said: "This contract award represents a significant milestone for Dolphin Drilling, materially strengthening our firm backlog to approximately USD 602 million. Importantly, it delivers long-term earnings visibility across two rigs in the UK, both rigs firmly secured on contract for the next five years, as we guided on and in line with the strategic plan for Dolphin.

With this enhanced backlog, we are establishing a more robust and cost-efficient operating platform, positioning the Company to generate sustainable cash flows and capture further opportunities in an increasingly tight offshore drilling market."
