Greenfire Resources Announces Preliminary Results
for Rights Offering
CALGARY, ALBERTA – September 16, 2026
– Greenfire Resources Ltd. (NYSE and TSX: GFR) (“Greenfire” or the “Company”) is pleased
to announce preliminary results of its C$775 million rights offering, which expired at 4:00 p.m. (Calgary time) on September 15, 2026
(the “expiration date”).
Upon closing of the rights offering, the Company
expects to issue 114,985,163 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 113,685,671 common shares subscribed for under the basic subscription privilege and
26,734,254 common shares subscribed for under the additional subscription privilege. Accordingly, 1,299,492 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 short form prospectus dated August 7, 2026.
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, September 16, 2026. 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 from the
rights offering to fully repay the Company’s C$575 million bridge facility and a portion of the other indebtedness incurred in connection
with the Company’s recent acquisition of Connacher Oil and Gas Limited.
This news release does not constitute an offer
to sell or the solicitation of an offer to buy the securities in any jurisdiction, nor shall there be any offer, solicitation or sale
of the securities in any jurisdiction in which such offer, solicitation or sale would be unlawful under the securities laws of such jurisdiction.
In the United States, the rights offering was made pursuant to a registration statement on Form F-10, filed with the US Securities and
Exchange Commission on August 7, 2026. The securities offered have not been approved or disapproved by any securities regulatory authority.

Exhibit 99.2

Greenfire Resources Announces Closing of Rights
Offering
CALGARY, ALBERTA – September 16, 2026
– Greenfire Resources Ltd. (NYSE and TSX: GFR) (“Greenfire” or the “Company”) is pleased
to announce the successful completion of its previously announced C$775 million offering of rights (the “Rights”) to
all eligible Greenfire shareholders to purchase additional common shares of the Company (the “Common Shares”) which
expired at 4:00 p.m. (Calgary time) on September 15, 2026 (the “Rights Offering”).
At the completion of the Rights Offering and pursuant
to the exercise of Rights, the Company issued an aggregate of 114,985,163 Common Shares, representing the maximum allotment available
to holders of Common Shares at the record date of August 17, 2026. Each Right entitled the holder thereof to acquire 0.9167 of a Common
Share, with no fractional Common Shares issued. Common Shares acquired pursuant to the exercise of Rights were issued at a price of C$6.74
or US$4.81 per Common Share for aggregate gross proceeds of approximately C$774 million (after conversion of U.S. dollar subscriptions).
114,041,317 Common Shares were issued under the basic subscription privilege and 943,846 Common Shares were issued under the additional
subscription privilege. As a result of the oversubscription, Common Shares subscribed for pursuant to the additional subscription privilege
were subject to proration in accordance with the terms of the Rights Offering, as set forth in the Company’s short form prospectus
dated August 7, 2026. As the Rights Offering was fully subscribed, the Company did not utilize the previously announced standby commitment
whereby certain limited partnerships comprising Waterous Energy Fund (collectively, ‘WEF”) agreed to acquire any Common
Shares not subscribed for under the Rights Offering.
As of the date hereof, the Company has 240,413,692
Common Shares issued and outstanding.
Upon completion of the Rights Offering, the Company
used the net proceeds thereof to fully repay the Company’s C$575 million bridge facility and a portion of the other indebtedness
incurred in connection with the Company’s recent acquisition of Connacher Oil and Gas Limited. Greenfire has approximately C$570
million drawn on its C$1.0 billion reserves-based revolving credit facility, which reflects a leverage level of approximately 1.2x Debt
/ 2027E Adjusted EBITDA at US$70 WTI.
Immediately prior to the completion of the Rights
Offering, WEF owned 90,317,640 Common Shares, representing approximately 72.0% of the issued and outstanding Common Shares, and 2,654,179
Common Share purchase warrants1 (“Warrants”) of Greenfire. Immediately after completion of the Rights Offering,
WEF owns 173,111,818 Common Shares and 2,654,179 Warrants representing approximately 72.0% of the issued and outstanding Common Shares
on an undiluted basis.
This news release does not constitute an offer
to sell or the solicitation of an offer to buy the securities in any jurisdiction. The securities being offered have not been approved
or disapproved by any securities regulatory authority.

Non-GAAP Measures and Ratios
Certain financial measures in this press release
are non-GAAP financial measures and ratios. These measures do not have a standardized meaning under IFRS Accounting Standards and therefore
may not be comparable to similar measures provided by other companies. These non-GAAP measures and ratios should not be considered
in isolation or as an alternative for measures of performance prepared in accordance with IFRS Accounting Standards.
| 1 | As a result of the completion
of Greenfire’s 2025 rights offering, the terms of the Warrants were adjusted effective December 17, 2025 pursuant to automatic
adjustment provisions contained in the Warrant agreements. Following such adjustments, the number of Common Shares issuable upon exercise
of each Warrant increased from 1.0000 to 1.1707, and the Warrant price was adjusted from US$11.50 to US$9.82 per Common Share. |

costs, refinancing costs and is adjusted for certain non-cash items, or other items that are considered non-recurring in nature or outside
of normal business operations.
Net income (loss) and comprehensive income (loss)
is the most directly comparable GAAP measure for adjusted EBITDA. For a reconciliation of Net income (loss) and comprehensive income (loss)
to Adjusted EBITDA for Greenfire for the years ended December 31, 2025 and 2024, please refer to Greenfire’s Management’s
Discussion & Analysis for the period ended December 31, 2025, which is available on the Company’s SEDAR+ profile at www.sedarplus.ca, and

Debt to Adjusted EBITDA

Debt by Adjusted EBITDA for a specified period.
