Trillion
Energy Announces Warrant Extension & Non-Brokered Private Placement Update
June
9, 2026 – Vancouver, B.C. – Trillion Energy International Inc. (“Trillion” or the “Company”) (CSE:
TCF) (OTCQB: TRLEF) (Frankfurt: Z62) is pleased to announce that, further to its previously announced non-brokered private placement
(the “Offering”), as described in the Company’s April 17, 2026 news release, it has closed 17,172,419 units (the “Units”)
for gross proceeds of CAD$1,501,900 and the settlement of CAD$1,073,963 in outstanding debt. Furthermore, the Company has extended the
expiry of 2,124,515 outstanding warrants by one year, as described below.
Private
Placement Update
The
Company issued 10,012,668 Units for gross proceeds of CAD$1,501,900 and settled outstanding debt with arm’s length and non-arm’s
length parties of CAD$1,073,963 through the issuance of an aggregate of 7,159,751 Units.
Each
Unit is comprised of one common share of the Company (each, a “Share”) and one-half of one share purchase warrant (each whole
warrant, a “Warrant”), with each Warrant exercisable at a price of CAD$0.25 per share for a period of one year from the date
of issuance.
In
connection with the Offering, Trillion paid an aggregate of CAD$53,240.05 in cash finder’s fees and issued an aggregate of 286,134
non-transferable broker warrants (“Broker Warrants”). Each Broker Warrant entitles the holder to one (1) Share and is exercisable
at a price of CAD$0.25 per share for a period of one year from the date of issuance.
The
Shares, Warrants and Broker Warrants issued in connection with the Offering are subject to hold periods ranging from August 28, 2026,
to October 6, 2026, in accordance with applicable securities laws and the policies of the CSE. The Offering remains subject to any applicable
approval of the CSE.
Proceeds
from the Offering will be used to fund contractual work program obligations on the M47 Concession under the Definitive Farm-In Agreement,
toward which the Company has paid a total of US$500,000 towards work commitments, audit and general corporate purposes, investor relations
activities, the expenses of the Offering, and general working capital.
Certain
insiders of the Company settled debt concurrent with the Offering through the issuance of an aggregate of 3,294,536 Units (the “Insider
Participation”). The Insider Participation is exempt from the valuation and minority shareholder approval requirements of Multilateral
Instrument 61-101 Protection of Minority Securityholders in Special Transactions (“MI 61-101”) by virtue of the exemptions
contained in Sections 5.5(a) and 5.7(1)(a) of MI 61-101, on the basis that the fair market value of such Insider Participation does not
exceed 25% of the Company’s market capitalization.
The
Company has also applied to the CSE to increase the size of the previously announced Offering to up to CAD$3,500,000, including the amounts
closed to date, and on the same terms and conditions, which would allow for the issuance of up to 23,333,333 Units at CAD$0.15 per Unit
to be issued. Use of proceeds for the increased Offering amount include to meet Trillion’s earn-in obligations in Turkey related
to Block M47 and additional working capital and general corporate expenses.

Warrant
Extension
The
2,124,515 warrants (the “2024 Warrants”) comprise 1,694,515 expiring June 28, 2026, 400,000 expiring July 3, 2026 and 30,000
expiring July 5, 2026, issued in tranche closings of a 2024 non-brokered private placement. The CAD$0.90 (post-consolidation) exercise
price is unchanged, and each expiry has been extended by one year to June 28, July 3 and July 5, 2027, respectively (the “Extension”),
subject to acceptance by the CSE. No action is required by holders, and the Extension does not apply to compensation or finder warrants,
which are not eligible for amendment.
Two
directors and one officer hold 517,776 of the 2024 Warrants, so the Extension may be a “related party transaction” under
MI 61-101. It is exempt from the formal valuation and minority shareholder approval requirements, as the fair market value of the insiders’
2024 Warrants does not exceed 25% of the Company’s market capitalization.
The
2024 Warrants remain subject to acceleration: the Company may advance the expiry to 30 days after notice to holders if its shares close
at or above CAD$1.75 on the CSE for seven consecutive trading days. All other terms remain unchanged.
Market
Making Engagement
The
Company has engaged Independent Trading Group, Inc. (“ITG”) to provide market-making services in accordance with the policies
of the CSE. The agreement is for an initial term of one month and automatically renews for successive one-month terms unless terminated
by either party on 30 days’ notice. The Company will pay ITG a cash fee of CAD$6,000 per month. There are no performance factors
in the agreement, and ITG will not receive any shares or options as compensation. The capital required for the market-making activities
will be provided by ITG. ITG and the Company are at arm’s length.
