**NEWS RELEASE**

**Greenbriar Announces Closing of Amendments to CAD $1.0 Million<br>Convertible Debenture and Warrants**

**Scottsdale, Arizona, June 29, 2026** - Greenbriar Sustainable Living Inc. (TSXV: **GRB**) (OTC: **GEBRF**) ("Greenbriar" or the "Company") is pleased to announce that, further to its news release dated June 24, 2026, it has received acceptance from the TSX Venture Exchange (the "Exchange") for amendments to the terms of its outstanding CAD $1.0 million unsecured convertible debenture originally issued on June 30, 2023 (the "Debenture").

The total proceeds of the Debenture are CAD $1,000,000, being the aggregate principal amount outstanding under the Debenture. The total proceeds do not include any accrued interest. Any accrued and unpaid interest owing under the Debenture may be settled in cash or, at the Company's election, through a shares-for-debt transaction. Any interest settled through a shares-for-debt transaction will be based on the market price of the Company's common shares at the time of settlement, in accordance with the policies of the Exchange.

The Company has amended the Debenture to extend the maturity date and conversion period by two years, from June 30, 2026 to June 30, 2028, and to reduce the conversion price of the Debenture from CAD $1.25 per common share to CAD $1.00 per common share, subject to adjustment in accordance with the terms of the Debenture.

The aggregate principal amount of CAD $1,000,000 outstanding under the Debenture is convertible into a maximum of 1,000,000 common shares at the amended conversion price of CAD $1.00 per common share, subject to adjustment in accordance with the terms of the Debenture.

The Debenture was originally issued pursuant to the Company's private placement announced on June 22, 2023, and closed on July 6, 2023. The Debenture bears interest at 12% per annum and was issued together with 460,000 detachable common share purchase warrants (collectively, the "Warrants"). The Debenture Holder is an arm's length party to the Company, and no insider of the Company holds the Debenture or the Warrants.

The Company has also amended the expiry date of the Warrants by extending the expiry date by two years, from June 30, 2026 to June 30, 2028. The exercise price of the Warrants remains unchanged at CAD $1.30 per common share, subject to adjustment in accordance with the terms of the Warrants.

All other terms of the Debenture and Warrants remain unchanged. The amendments to the Debenture and Warrants have been accepted by the Exchange and are effective on or about June 30, 2026.
