STAMPER REVISES NAMIBIA ACQUISITION TERMS, REDUCING CASH CONSIDERATION

VANCOUVER, BC, Sept. 22, 2026 /CNW/ -- Stamper Oil & Gas Corp. ("Stamper" or the "Company") (TSX-V: STMP) (US OTC: STMGF) (Germany: TMP0) announces that it has entered into an amending agreement dated September 17, 2026 (the "Amending Agreement") that revises the remaining deferred consideration payable under the share purchase agreement relating to the Company's acquisition of indirect interests in certain offshore Namibian oil and gas assets (the "Original Agreement"). The acquisition was completed on September 10, 2025.

Grayson M. Andersen, Chief Executive Officer of Stamper, stated: "The revised structure reduces Stamper's remaining cash acquisition obligation by US$750,000 and stages the equity consideration over 18 months, providing greater flexibility to allocate capital toward advancing our offshore Namibia portfolio. It also maintains vendor alignment through equity ownership, leaving the acquired asset interests and all other terms of the original transaction unchanged. Stamper's asset base is situated adjacent to a number of high-impact exploration wells planned to be drilled in the next 12 months, while the Company continues to work with its partners to pursue farm-out transactions and advance seismic acquisition and future drilling programs."

Revised Deferred Consideration

Under the Amending Agreement, the deferred consideration has been revised to include aggregate cash payments of US$500,000 and the issuance of 16,500,000 common shares of the Company (the "Consideration Shares"). Under the Original Agreement, the remaining deferred consideration consisted of US$1,250,000 in cash and 8,561,644 common shares. The cash consideration is payable during 2026, with US$300,000 payable on or before October 30, 2026, and the remaining US$200,000 payable on or before December 31, 2026. The Consideration Shares vest in stages over an 18-month period, with 10% on signing of the Amending Agreement, 20% in six months, 20% in 12 months, 25% in 14 months and 25% in 18 months. The revised cash payments and Consideration Shares constitute the final acquisition consideration payable by the Company under the Original Agreement in respect of the acquired assets. Upon payment and issuance in accordance with the Amending Agreement, no further cash, equity or other acquisition consideration will be payable by the Company for those assets. All other terms and conditions of the Original Agreement remain unchanged and in full force and effect.

The Amending Agreement and the issuance of the Consideration Shares remain subject to acceptance by the TSX Venture Exchange and any other required regulatory approvals. The Consideration Shares will be subject to applicable statutory hold periods and any escrow or resale restrictions imposed by the Exchange.
