Additional Information and Where to Find It

A full description of the terms of the proposed business combination have been provided in a registration statement on Form F-4 (as it may be amended, the “Registration Statement”) filed by PubCo with the Securities and Exchange Commission (“SEC”) on April 21, 2023, as amended on June 15, 2023, which includes a preliminary prospectus and proxy statement of MBSC, referred to as a proxy statement/prospectus. PubCo and MBSC urge investors, stockholders and other interested persons to read the preliminary proxy statement/prospectus, as well as other documents filed with the SEC, because these documents contain or will contain important information about the PubCo, MBSC, Greenfire and the proposed business combination. After the registration statement is declared effective, the definitive proxy statement/prospectus to be included in the registration statement will be mailed to stockholders of MBSC as of a record date to be established for voting on the proposed business combination. Stockholders may obtain a copy of the registration statement on Form F-4 including the proxy statement/prospectus, and other documents filed with the SEC without charge, by directing a request to: Greenfire Resources Inc., 1900 – 205 5th Avenue SW, Calgary, AB T2P 2V7, and M3-Brigade Acquisition III Corp., 1700 Broadway, 19th Floor, New York, NY 10019. The preliminary proxy statement/prospectus and, once available, the definitive proxy statement/prospectus, to be included in the Registration Statement can also be obtained, without charge, at the SEC’s website (www.sec.gov).

Participants in Solicitation

PubCo, MBSC and Greenfire, and their respective directors and executive officers, may be deemed participants in the solicitation of proxies of MBSC’s stockholders in respect of the proposed business combination. Information about the directors and executive officers of MBSC is set forth in MBSC’s filings with the SEC. Information about the directors and executive officers of PubCo and Greenfire and more detailed information regarding the identity of all potential participants, and their direct and indirect interests by security holdings or otherwise, will be set forth in the definitive proxy statement/prospectus for the proposed business combination when available. Additional information regarding the identity of all potential participants in the solicitation of proxies to MBSC’s stockholders in connection with the proposed business combination and other matters to be voted upon at the special meeting, and their direct and indirect interests, by security holdings or otherwise, will be included in the definitive proxy statement/prospectus, when it becomes available.

Many factors could cause actual future events to differ materially from the forward-looking statements in this communication, including but not limited to: (i) the timing to complete the proposed business combination by MBSC’s business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by MBSC; (ii) the occurrence of any event, change or other circumstances that could give rise to the termination of the definitive agreements relating to the proposed business combination; (iii) the outcome of any legal, regulatory or governmental proceedings that may be instituted against PubCo, MBSC, Greenfire or any investigation or inquiry following announcement of the proposed business combination, including in connection with the proposed business combination; (iv) the inability to complete the proposed business combination due to the failure to obtain approval of MBSC’s stockholders or the inability to receive approval of the proposed plan of arrangement in connection with the proposed business combination; (v) Greenfire’s and PubCo’s success in retaining or recruiting, or changes required in, its officers, key employees or directors following the proposed business combination; (vi) the ability of the parties to obtain the listing of PubCo’s common shares and warrants on the New York Stock Exchange upon the closing of the proposed business combination; (vii) the risk that the proposed business combination disrupts current plans and operations of Greenfire; (viii) the ability to recognize the anticipated benefits of the proposed business combination; (ix) unexpected costs related to the proposed business combination; (x) the amount of redemptions by MBSC’s public stockholders being greater than expected; (xi) the management and board composition of PubCo following completion of the proposed business combination; (xii) limited liquidity and trading of PubCo’s securities; (xiii) geopolitical risk and changes in applicable laws or regulations; (xiv) the possibility that Greenfire or MBSC may be adversely affected by other economic, business, and/or competitive factors; (xv) operational risks; (xvi) the possibility that the COVID-19 pandemic or another major disease disrupts Greenfire’s business; (xvii) litigation and regulatory enforcement risks, including the diversion of management time and attention and the additional costs and demands on Greenfire’s resources; (xix) the risks that the consummation of the proposed business combination is substantially delayed or does not occur; (xx) risks associated with the oil and gas industry in general (e.g., operational risks in development, exploration and production; disruptions to the Canadian and global economy resulting from major public health events, the Russian-Ukrainian war and the impact on the global economy and commodity prices; the impacts of inflation and supply chain issues and steps taken by central banks to curb inflation; pandemic, war, terrorist events, political upheavals and other similar events; events impacting the supply and demand for oil and gas including the COVID-19 pandemic and actions taken by the OPEC + group; delays or changes in plans with respect to exploration or development projects or capital expenditures); (xxi) the uncertainty of reserve estimates; (xxii) the uncertainty of estimates and projections relating to production, costs and expenses; (xxiii) health, safety and environmental risks; (xxiv) commodity price and exchange rate fluctuations; (xxv) changes in legislation affecting the oil and gas industry; and (xxvi) uncertainties resulting from potential delays or changes in plans with respect to exploration or development projects or capital expenditures. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of MBSC’s registration on Form S-1 (Registration Nos. 333-256017 and 333-260423), MBSC’s annual report on Form 10-K for the year ended December 31, 2022 filed with the SEC on March 31, 2023, the Registration Statement, which includes a preliminary prospectus and proxy statement of MBSC, referred to as a proxy statement/prospectus, MBSC’s quarterly report on Form 10-Q for the quarter ended March 31, 2023 filed with the SEC on June 2, 2023 and other documents filed by MBSC or PubCo from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and PubCo, MBSC and Greenfire assume no obligation and do not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. Neither PubCo, MBSC nor Greenfire gives any assurance that either PubCo, MBSC nor Greenfire will achieve its expectations.
