ORGANIZATION AND BUSINESS OPERATIONS	Note 1 — ORGANIZATION AND BUSINESS OPERATIONS Montana Technologies Corporation (the “Company”) was established to pursue the development and expected commercialization of various technological innovations and may engage in any activity or purpose permitted for a corporation organized in Delaware. The Company has created a transformational technology that provides significant energy efficiency gains in air conditioning and comfort cooling applications, as well as a potential source of potable water, all through its proprietary “AirJoule®” units. Power & Digital Infrastructure Acquisition II Corp (“XPDB”) entered into an Agreement and Plan of Merger (the “Merger Agreement”), dated June 5, 2023, as amended on February 5, 2024, with XPDB Merger Sub, LLC, a direct wholly-owned subsidiary of XPDB (“Merger Sub”), and Montana Technologies LLC (“Legacy Montana”). On March 14, 2024, pursuant to the Merger Agreement, Merger Sub was merged with and into Legacy Montana, with the Legacy Montana surviving the merger as a wholly-owned subsidiary of XPDB (the “Merger” and, together with the other transactions contemplated by the Merger Agreement, the “Business Combination”). In connection with closing the Business Combination (the “Closing”), XPDB changed its name from “Power & Digital Infrastructure Acquisition II Corp.” to “Montana Technologies Corporation.” Prior to the Business Combination, all of the outstanding preferred units of Legacy Montana were converted into Class B common units. As a result of the Business Combination, (i) each issued and outstanding Class B common unit and Class C common unit of Legacy Montana was converted into the right to receive approximately 23.8 shares of newly issued shares of Class A common stock of Montana Technologies Corporation, (ii) each issued and outstanding class A common unit of Legacy Montana converted into the right to receive approximately 23.8 shares of newly issued shares of Class B common stock of Montana Technologies Corporation and (iii) each option to purchase common units of Legacy Montana converted into the right to receive an option to purchase Class A common stock of Montana Technologies Corporation having substantially similar terms to the corresponding option, including with respect to vesting and termination-related provisions, except that such options represented the right to receive a number of shares of Class A common stock equal to the number of common units subject to the corresponding option immediately prior to the Closing multiplied by approximately 23.8. The Business Combination was accounted for as a reverse recapitalization in accordance with U.S. generally accepted accounting principles (“GAAP”). Under this method of accounting, although XPDB acquired the outstanding equity interest in Legacy Montana in the Business Combination, XPDB is treated as the “acquired company” and Legacy Montana was treated as the accounting acquirer for financial statement purposes. Accordingly, the Business Combination was treated as the equivalent of Legacy Montana issuing stock for the net assets of XPDB, accompanied by a recapitalization. Furthermore, the historical financial statements of Legacy Montana became the historical financial statements of the Company upon the consummation of the merger. As a result, the condensed consolidated financial statements reflect (i) the historical operating results of Legacy Montana prior to the Business Combination; (ii) the combined results of XPDB and Legacy Montana following the Closing; (iii) the assets and liabilities of Legacy Montana at their historical cost and (iv) Legacy Montana’s equity structure for all periods presented, as affected by the recapitalization presentation after completion of the Business Combination. See Note 5 – Recapitalization (As Restated) for further details of the Business Combination. In connection with the Business Combination, XPDB entered into a subscription agreement (the “Subscription Agreement”) with Rice Investment Group (the “PIPE Investor”), pursuant to which, among other things, the PIPE Investor agreed to subscribe for and purchase from XPDB, and XPDB agreed to issue and sell to the PIPE Investor, an aggregate of 588,235 newly issued shares of Class A common stock (the “Committed Shares”) on the terms and subject to the conditions set forth therein. On March 14, 2024, in connection with the Closing, the Company consummated the issuance and sale of the Committed Shares to the PIPE Investor.
