Greenbriar Announces Non-Brokered Private Placement

TSX Venture Exchange: GRB

US OTC Market: GEBRF

Scottsdale, Arizona, October 6th, 2026 - Greenbriar Sustainable Living Inc. (TSXV: GRB) (OTC: GEBRF) ("Greenbriar" or the "Company") announces that it has arranged a private placement of 2,200,000 units at CDN $0.45 per unit for total proceeds of CDN $990,000.00. Each unit comprises one common share and one full common share purchase warrant. Each warrant is exercisable to acquire one common share at CDN $0.55 per share for a period of 36 months. Proceeds are for mainly Sage Ranch engineering costs to file the final construction permits for grading, sewer, drainage, water, curb, gutter, internal roads and dry utilities. The units are subject to a four (4) month hold period. The private placement is subject to the approval of the TSX Venture Exchange and the Board. No finder's fees will be paid in connection with the private placement.

The CEO of the company will cash fund one million units and the President 200,000 units.

Further to the company receiving AGM approval for up to CAD $8 million in convertible preferred shares at CAD $1.00 per share, the company has between $6.5 million to $8 million in debt holders willing to convert, and will issue the subscription agreements this week. The preferred shares have no special voting rights and will only have one vote per share. This shows good leadership from the company with the conversion at CAD $1.00 per share into common at 1 for 1. There is no fixed or mandatory interest rate or payment, no mandatory redemptions and are perpetual. The board may vote at its discretion at any time to issue a dividend, but at a maximum of 8% per year and cumulative if voted affirmative. This moves between CAD $6.5 million to CAD $8 million from the liabilities into the equity account and cleans up the balance sheet. The company may seek the preferred shares to be listed.
