Early Warning Disclosure Regarding Christopher B. Tatum

Christpher B. Tatum ("Kit Tatum") previously filed an early warning report with respect to the securities of Appia on June 30, 2025. As a result of an increase in the issued and outstanding capital of Appia pursuant to the exercise of warrants, including the acquisition by Kit Tatum of 3,000,000 common shares (the "3,000,000 Shares") on the exercise of 3 million warrants at $0.15 per warrant, and the expiry of 6,375,000 warrants held by Kit Tatum, the interest of Kit Tatum in Appia has been reduced to approximately 8.36% of the issued and outstanding common shares of Appia on a non-diluted basis and a partially diluted basis. Kit Tatum is therefore no longer required to file an early warning report under National Instrument 62-103.

Kit Tatum has advised that the 3,000,000 Shares were acquired for investment purposes and that he has no present intention to either increase or decrease his holdings in the Company. Notwithstanding the foregoing, he has advised that he may increase or decrease his beneficial ownership, control or direction over common shares of the Company through market transactions, private agreements, other treasury issuances or otherwise.

This news release is issued pursuant to National Instrument 62-103 - The Early Warning System and related Take-Over Bid and Insider Reporting Issues of the Canadian Securities Administrators, which also requires an early warning report to be filed with the applicable securities regulators containing additional information with respect to the foregoing matters. A copy of this early warning report in respect of this transaction will be available on Appia's issuer profile on SEDAR+ at www.sedarplus.ca.
