Corporate Announcement on FY25 & Dividend Payment

February 26, 2026

An Final Dividend of US5 cents (United States Five Cents) and a Special Dividend of US3.3 cents (United States Three point Three 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 May 15, 2026.

To enable Seplat Energy's Registrar, Datamax Registrars Limited ("DataMax"), prepare for the payment of the dividends, the Register of Shareholders will be closed on May 18, 2026.

Close of Business on May 15, 2026.

Note that on the London Stock Exchange: The Associated Record Date will be May 15, 2026, and the Ex-Dividend date will be May 14, 2026.

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 May 14, 2026, and will be communicated by the Company on May 15, 2026.

On or around May 29, 2026, the final and special dividends will be paid electronically to shareholders whose names appear on the Register of Members as of May 15, 2026, and who have completed the e-dividend registration and mandated the Registrar to pay their dividends directly into their Bank accounts.

Shareholders who are yet to complete the e-dividend registration are advised to download the form either from DataMax Registrars Limited's website at http://www.datamaxregistrars.com or from Seplat Energy's website at https://www.seplatenergy.com/investors/dividend-information/, complete and submit to Datamax or their respective Banks. Holders of shares through depositary interests on the LSE should please provide their account details to the Company's UK depositary, Computershare.

Shareholders with dividend warrants and share certificates that have remained unclaimed or are yet to be presented for payment or returned for validation are advised to complete the e-dividend registration or contact the Registrar.
