PetroNor E&P ASA: Interim financial report for the quarter ended 31 March 2026

Oslo, 29 May 2026: In the first quarter, PetroNor E&P ASA ("PetroNor" or the "Company") delivered net production of 4,712* bopd, up from 4,303 bopd in Q1 2025.

“We delivered a solid operational quarter, with production continuing to improve following the completion of the infill drilling campaign. New wells have exceeded expectations and support the case for further infill activity in the field,” says CEO Jens Pace.

No entitlement oil liftings occurred in the first quarter, resulting in inventory build-up at the Djeno terminal. At the beginning of April 2026, the Company completed a lifting and sale of approximately 964,593 barrels of oil, generating cash proceeds of about USD 112 million.

A shareholder distribution of NOK 3.25 per share was approved by the Annual General Meeting held on 28 May 2026. The distribution is expected to be paid in June 2026, subject to customary approvals.
