TrillionEnergy Announces Asset Disposition and Royalty Agreement

April10, 2026 — Vancouver, B.C. — Trillion Energy International Inc. (“Trillion” or the “Company”) (CSE: TCF) (OTCQB: TRLEF) (Frankfurt: Z62) announces that, through a subsidiary it has entered into a sale agreement for all the issued and outstanding shares of Park Place Energy Turkiye Limited (“PPET”), which owns the Company’s licence interests in the South Akcakoca Sub-Basin (SASB) natural gas project and the Cendere oil field (“the Licences”).

Key elements of the sale transaction include: Transfer of approximately US$20 million in associated liabilities of PPET to the purchaser and retention of a 7% Gross Overriding Royalty (GORR) on future production revenues from the Licences to be paid to Trillion. The Company will further benefit from eliminating >USD$20m legacy liabilities from its balance sheet, as well as further ongoing capital and operational commitments tied to mature assets, while preserving long-term upside through royalty exposure.

Key terms of the Royalty include: a) effective when cumulative gross revenues from the Licenses post-closing exceed US$7,500,000, and b) any future disposition of the Licenses will trigger crystallization of the Royalty, requiring valuation and payment of 7% of the gross value attributed to the Licenses in such disposition.
