On Market Share Buyback

Savannah Energy PLC, the British independent energy company focused around the delivery of Projects that Matter, announces that the Company has today completed an on-market share buyback programme (the "Buyback Programme"). The Company may undertake further share buybacks opportunistically pursuant to the buyback authority granted by shareholders at the general meeting held on 28 November 2025, subject to the Company being in an open period and not being in possession of inside information and having regard to corporate liquidity and prevailing market conditions.

Under the Buyback Programme, the Company has repurchased a total of 32,063,641 ordinary shares in the Company ("Ordinary Shares") (the "Buyback Shares") at 6.8 pence per share for a total consideration of approximately £2.18 million. The Company confirms that all of the Buyback Shares will be cancelled imminently.

The Buyback Programme was conducted in accordance with the authority granted to the Company by its shareholders at the general meeting held on 28 November 2025, which permits the purchase by the Company of up to 318,098,135 of its Ordinary Shares.

Total Voting Rights

Following completion of the Buyback Programme and the repurchase and cancellation of the Buyback Shares, the Company's issued share capital will consists of 2,088,590,594 Ordinary Shares (the "Adjusted Share Capital"). The Company does not hold any Ordinary Shares in treasury and accordingly this will be the total number of voting rights and may be used by shareholders as the denominator for the calculations by which they determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules. 

NIPCO Plc Shareholding

The Company notes that, as at 5 February 2026, NIPCO Plc ("NIPCO"), the Company's largest shareholder, is now interested in 631,479,202 Ordinary Shares representing approximately 30.23% of the Company's voting share capital based on the Adjusted Share Capital, including through Purebond Limited's holding of 1.7 million shares in the Company. The 30% threshold was crossed as a result of the Buyback Programme (rather than through NIPCO acquiring further interests in shares) and, accordingly, in accordance with Note 1 on Rule 37.1 of the City Code on Takeovers and Mergers (the "Takeover Code"). NIPCO is not required either now, or on completion of Unsettled Purchases (as defined below), to make a mandatory offer for the Company.

The current aggregate registered ownership of Ordinary Shares of NIPCO and Purebond represents approximately 27.93% of the Company's voting share capital based on the Adjusted Share Capital. The Company further notes that when NIPCO receives the approximately 48.15 million Ordinary Shares which have not yet settled pursuant to the acquisition of Ordinary Shares by NIPCO announced on 30 December 2025) (the "Unsettled Purchases"), the aggregate ownership of Ordinary Shares of NIPCO and Purebond will, following such settlement be approximately 30.23%.

However, as NIPCO is now interested in more than 30%, but less than 50%, of the voting share capital of the Company based on the Adjusted Share Capital, NIPCO (and any of its concert parties) may not acquire a further interest in shares with voting rights in the Company without incurring an obligation under Rule 9 of the Takeover Code to make a mandatory offer.
