Selene Deferred Payment Agreement

Further to Deltic's announcement on 12 December 2025, the Company announces that it has agreed with Shell U.K. Limited ("Shell") an extension to the payment date of amounts owed to Shell by Deltic in relation to: (i) in aggregate, £1,530,320, being the sums that have accrued to Deltic's account in relation to the successful Selene exploration well from April 2025 to October 2025; and (ii) any further sums accruing to Deltic in relation to Selene after October 2025 (together the "Deferred Amounts"). 

The payment date of the Deferred Amounts has now been deferred to 27 May 2026, although Deltic may request extensions of this date for up to a further six months, with the decision to grant any such extensions being at Shell's sole discretion.
