Vancouver, British Columbia--(Newsfile Corp. - May 21, 2026) - Trillion Energy International Inc. (CSE: TCF) (OTCQB: TRLED) (FSE: Z62) ("Trillion" or the "Company") is pleased to announce that the Company intends to extend the expiry date of an aggregate of 4,633,965 outstanding post-consolidation warrants issued in connection with various tranche closings of a non-brokered private placement of which 2,646,471 warrants were issued on May 28, 2024, 1,228,444 warrants were issued on May 31, 2024, 306,495 warrants were issued on June 10, 2024 and 452,555 warrants were issued on June 19, 2024 (the "2024 Warrants").

The exercise price of the 2024 Warrants is $0.90 (post consolidation) and remains unchanged. The 2024 Warrants have original expiration dates of May 28, 2026, May 31, 2026, June 10, 2026 and June 19, 2024. The Company proposes to extend each of the expiration dates of the 2024 Warrants by one additional year to May 28, 2027, May 31, 2027, June 10, 2027 and June 19, 2027, respectively (the "Extension").

The Canadian Securities Exchange (the "CSE") has granted an exemption from the requirement of Section 6.7(3)(d) (at least 10 trading days remain before the expiry date) of CSE Policy 6 to permit the Company to undertake the Extension. No action will be required on the part of the holders of the 2024 Warrants to give effect to the Extension. In accordance with the requirements of the CSE, the terms of any warrants issued as compensation warrants or as finder warrants are not eligible for amendment.

As one of the directors of the Company is the beneficial owner of 160,000 of the 2024 Warrants, the Extension may constitute a "related party transaction" as defined under Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Extension is exempt from the formal valuation and minority shareholder approval requirements under MI 61-101 as the fair market value of the 2024 Warrants issued to insiders does not exceed 25% of the market capitalization of the Company.

The 2024 Warrants will continue to be subject to an acceleration provision whereby the Company may accelerate the expiry date to a date that is 30 calendar days following notice to the holders if the closing price of the Company's Shares on the CSE is equal to or greater than C$1.75 for a period of seven consecutive trading days.

All other terms and conditions of the 2024 Warrants will remain unchanged.
