Calgary, Alberta--(Newsfile Corp. - December 17, 2025) - Greenfire Resources Ltd. (NYSE: GFR) (TSX: GFR) ("Greenfire" or the "Company") today announced preliminary results of its C$300 million rights offering, which expired at 4:00 p.m. (Calgary time) on December 16, 2025 (the "expiration date").

Upon closing of the rights offering, the Company expects to issue 55,147,058 common shares, representing the maximum number of common shares available under the rights offering, without reliance on the standby commitment provided by certain limited partnerships comprising Waterous Energy Fund. Preliminary results indicate that the rights offering was oversubscribed, with 53,567,940 common shares subscribed for under the basic subscription privilege and 23,794,471 shares subscribed for under the additional subscription privilege. Accordingly, 1,579,118 common shares, being the difference between the maximum number of common shares available under the rights offering and those subscribed for under the basic subscription, are expected to be allocated on a pro rata basis among holders who exercised their additional subscription privilege pursuant to the procedures set forth in the Company's rights offering circular dated November 5, 2025. Such results are preliminary in nature and are subject to change following the final count of subscription forms and closing procedures by the rights agent. The Company will provide a further update of the final results of the rights offering once confirmed.

Greenfire expects that the rights offering will close today, December 17, 2025. The Company's rights agent expects to provide DRS statements evidencing new common shares acquired through the rights offering to registered holders as soon as practicable thereafter. If a holder did not validly exercise his or her subscription rights prior to the expiration date, such rights have expired and are void and have no value.

The Company intends to use the proceeds less offering expenses, together with cash on hand, to fund the redemption of the Company's outstanding US$237.5 million aggregate principal amount of 12.00% senior secured notes due 2028.
