Deltic Energy Plc ("Deltic" or "the Company")

Selene Deferred Payment Agreement

Deltic announces that it has entered into a deferred repayment agreement (the "Deferred Repayment Agreement") with Shell U.K. Limited ("Shell") as operator of the P2437 licence ("Selene"), in relation to the payment of: (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"). 

Under the Deferred Repayment Agreement, Deltic's payment of the Deferred Amounts to Shell has been deferred to 27 February 2026, although Deltic may request extensions of this date for a total of up to nine months, with the decision to grant any such extensions being at Shell's sole discretion. 

The Deferred Repayment Agreement's terms include a non-compounding interest payable to Shell at the Bank of England Base Rate plus 8% with interest payable monthly. The Deferred Repayment Agreement is unsecured and contains customary representations, warranties, undertakings and events of default. The Deferred Repayment Agreement also contains provisions whereby Shell will be entitled to require early repayment of the Deferred Amounts 30 days following a change of control of Deltic; and also where Shell will be entitled to declare the Deferred Amounts repayable upon Deltic performing an assignment of its interest in Selene. 

Deltic has drawn down the full £2.7 million available to it under the bridging facility provided by RockRose Energy Limited as part of the proposed all cash acquisition of Deltic Energy Plc. As of 30 November 2025 Deltic had unaudited cash of £1.90 million and, as a result of securing the Deferred Payment Agreement, is funded for working capital purposes until at least mid-2026.
