An Interim Dividend of US4.6 cents (United States Four point Six Cents) per Ordinary Share of N0.50k each, (subject to appropriate withholding tax) will be paid to shareholders whose names appear in the Register of Members as at the close of business on August 13, 2025.

To enable Seplat Energy's Registrar, Datamax Registrars Limited ("DataMax"), prepare for the payment of the interim dividend, the Register of Shareholders will be closed on August 14, 2025.

Close of Business on August 13, 2025.

Note that on the London Stock Exchange: The Associated Record Date will be August 13, 2025, and the Ex-Dividend date will be August 12, 2025.

The dividend will be paid in Naira and US Dollars only. The default currency for the dividend will depend as follows:

·      Shareholders holding their shares on the Nigerian Exchange Limited without a valid Nigerian Certificate for Capital Importation ("CCI") will be paid their dividend in Naira as the default currency;

·      Shareholders holding their shares on the Nigerian Exchange Limited with a valid CCI will be paid their dividend in US dollars as the default currency.  Evidence of the CCI must be provided to Datamax. However, those shareholders may instead elect to receive their entire dividend payment in Naira (partial elections are not permissible); and

·      Shareholders holding their shares through depository interests on the London Stock Exchange will be paid their dividend in US dollars as the default currency.

The dividend will be paid in US Dollars and Naira only. The shareholders holding their shares on the Nigerian Exchange Limited who hold a valid CCI should notify DataMax of that fact. Those who hold a valid CCI but wish to receive their dividends in Naira, should also inform Datamax and complete an e-mandate Form. The e-mandate form can be downloaded from the website of DataMax at https://www.datamaxregistrars.com

The exchange rate for the Naira amounts payable will be determined by reference to the relevant exchange rates applicable to the US dollar on August 12, 2025, and will be communicated by the Company on August 13, 2025.

On or around August 28, 2025, the interim dividend will be paid electronically to shareholders whose names appear on the Register of Members as of August 13, 2025 and who have completed the e-dividend registration and mandated the Registrar to pay their interim dividend directly into their Bank accounts.
