UPDATE ON PROPOSED CASH ACQUISITION

of

Mobil Producing Nigeria Unlimited ("MPNU")

by

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

Lagos and London, 24 May 2023: Seplat Energy announces that it has extended with Mobil Development Nigeria Inc. and Mobil Exploration Nigeria Inc. ("ExxonMobil") the Share Sale and Purchase Agreement ("SSPA") for the acquisition of ExxonMobil's share capital of Mobil Producing Nigeria Unlimited ("MPNU") (the "Transaction"), in order to preserve the Transaction pending the resolution of certain legal proceedings and receipt of applicable regulatory approvals.

In addition, the parties have revised the SSPA such that, in the event that applicable regulatory approvals are obtained and the Transaction closes, ExxonMobil would share in a portion of the value that would otherwise accrue to Seplat Energy in the period between the effective economic date and the completion date of the Transaction. The exact amount will depend on a number of factors, including production by MPNU and oil price. Except as disclosed herein, there has been no significant change in terms of the announcement dated 25 February 2022, and the headline consideration, effective date and the contingent payment structure remain unchanged.

Seplat Energy continues to engage key stakeholders and remains committed to completing the Transaction as soon as possible.
