Note: Schedules filed in paper format shall include a signed original and five copies of the schedule, including all exhibits. See Rule 13d-7(b) for other parties to whom copies are to be sent.

The information required on the remainder of this cover page shall not be deemed to be “filed” for the purpose of Section 18 of the Securities Exchange Act of 1934 (“Act”) or otherwise subject to the liabilities of that section of the Act but shall be subject to all other provisions of the Act (however, see the Notes).

This statement on Schedule 13D (the “Schedule 13D”) relates to the shares of Class A common stock, par value $0.0001 per share (the “ Class A Common Stock”), of Montana Technologies Corporation, a Delaware corporation (the “Issuer”), whose principal executive office is located at 34361 Innovation Drive, Ronan, MT 59864.

The Schedule 13D is being filed by the following persons (each a “Reporting Person” and, collectively, the “Reporting Persons”):

Stuart D. Porter,

Three Curve Holding Corporation, and

Three Curve Capital LP (“Three Curve LP”).

Three Curve Holding Corporation and Three Curve LP are organized under the laws of the State of Delaware. Mr. Porter is a citizen of the United States of America.

The business address for each of the Reporting Persons is 185 Dartmouth Street, 7th Floor, Boston, MA 02116.

Mr. Porter is the Chief Executive Officer and Chief Investment Officer of Denham Capital and a director of the Issuer. Three Curve LP is an entity formed for the purpose of investing in securities. Three Curve Holding Corporation is its general partner. The directors and officers of Three Curve Holding Corporation (collectively, the “Related Persons”) are listed on Schedule A, which is incorporated herein by reference.

During the last five years, none of the Reporting Persons or, to the best of their knowledge, the Related Persons (i) has been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 4 below summarizes certain provisions of the Merger Agreement (as defined below) that pertain to the securities acquired by Three Curve LP. Pursuant to the Merger Agreement, upon consummation of the Business Combination (as defined below), Three Curve LP received 18,755,774 shares of Class A Common Stock and Mr. Porter received 294,118 shares of Class A Common Stock.

Business Combination

On March 14, 2024 (the “Closing Date”), pursuant to an Agreement and Plan of Merger, dated as of June 5, 2023 and as amended on February 5, 2024 (as so amended, the “Merger Agreement”), by and among Power & Digital Infrastructure Acquisition II Corp., a Delaware corporation (“XPDB”), XPDB Merger Sub, LLC, a Delaware limited liability company, and the wholly owned subsidiary of XPDB (“Merger Sub”), and Montana Technologies LLC, a Delaware limited liability company (“Legacy Montana”), Merger Sub merged with and into Legacy Montana (the “Merger” and, together with the other transactions contemplated by the Merger Agreement, the “Business Combination”), with Legacy Montana surviving the Merger as a wholly owned subsidiary of XPDB. XPDB was renamed on the Closing Date to “Montana Technologies Corporation.”

As a result of the Business Combination, (i) each holder of Legacy Montana Class B common units and Class C common units was issued shares of Class A Common Stock of the Issuer, with a $10.00 value ascribed to each such share and which will entitle the holder to one vote per share on all matters submitted to a vote of the holders of Class A Common Stock, whether voting separately as a class or otherwise, (ii) the holder of Legacy Montana Class A common units was issued shares of Class B common stock, par value $0.0001 of the Issuer (the “Class B Common Stock”), with a $10.00 value ascribed to each such share and which will entitle the holder to the holder to one vote per share on all matters submitted to a vote of the holders of Class B Common Stock, whether voting separately as a class or otherwise, and (iii) each holder of Legacy Montana stock options were issued stock options of the Issuer with substantially similar terms. Each share of Class B Common Stock is convertible into one share of Class A Common Stock at the option of the holder at any time upon written notice to the transfer agent of the Issuer. The Class B Common Stock will automatically convert into Class A Common Stock at the earliest of (1) the date that is seven years from the effective date of the Issuer’s Second Amended and Restated Certificate of Incorporation (the “Charter”) and (2) the first date on which the permitted holders of Class B Common Stock cease to own, in the aggregate, at least 33.0% of the number of Class B Common Stock issued following the effectiveness of the Charter, as equitably adjusted to reflect any stock splits, reverse stock splits, stock dividends, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change or transaction.

Certain Legacy Montana equityholders, including Mr. Porter and Three Curve LP, will have the right to receive additional equity consideration (in each case, in accordance with their respective pro rata share) in the form of shares of Class A Common Stock, with a $10.00 value ascribed to each share (the “Earnout Shares”), upon full completion of construction and operational viability (including all permitting, regulatory approvals and necessary or useful inspections) of new production capacity of the Issuer’s key components or assemblies based solely on demand from bona fide customer commitments evidenced by binding contracts (or in the discretion of a majority of the independent members of the board of directors of the Issuer (the “Board”), a non-binding letter of intent or indication of interest or similar writing that is substantially likely to become a binding contract) with a known price or pricing formula that exceeds a level of production capacity that is expected to generate Annualized EBITDA (as defined in the Merger Agreement) of more than $150,000,000 (the “Threshold Annualized EBITDA”), which shall be determined by a majority of the independent members of the Board in their sole discretion, equal to (i) the ratio of (x) (1) the Annualized EBITDA that is expected from such new production capacity (the “Expected Annualized EBITDA”) less (2) (A) the Threshold Annualized EBITDA plus (B) all previously Expected Annualized EBITDA amounts associated with previous new production capacities for which previous earnouts were achieved, divided by (y) $150,000,000 multiplied by (ii) $200,000,000, provided that the aggregate Expected Annualized EBITDA shall not exceed $300,000,000. The maximum value of the Earnout Shares will be capped at $200 million and the ability to receive Earnout Shares will expire on the fifth anniversary of the Closing Date.

Registration Rights Agreement

On the Closing Date, the Issuer, XPDI Sponsor II LLC (“Sponsor”) and certain investors of the Issuer, including Mr. Porter and Three Curve LP, entered into a registration rights agreement (the “Registration Rights Agreement”), pursuant to which the Issuer agreed to register for resale, pursuant to Rule 415 under the Securities Act of 1933, as amended, certain shares of Class A Common Stock and other equity securities of the Issuer that are held by the parties thereto from time to time (the “Registrable Securities”), and agreed to provide customary “piggyback” registration rights, subject to certain requirements and customary conditions. Pursuant to the Registration Rights Agreement, the Issuer will file a shelf registration statement registering the resale of the Registrable Securities within 30 days after the execution of the Registration Rights Agreement. At any time and from time to time when an effective shelf registration is on file with the Securities and Exchange Commission (the “SEC”), certain investors may request to sell all or any portion of their Registrable Securities in an underwritten offering so long as the total offering price is reasonably expected to exceed $25.0 million. The Issuer will be responsible for certain expenses relating to such registrations and indemnify the stockholders against certain liabilities.

Lock-Up Agreements

On the Closing Date, the Issuer, Sponsor, former independent directors of XPDB and certain investors of the Issuer, including Three Curve LP, entered into lock-up agreements, (each, the “Lock-Up Agreement”), pursuant to which the parties will, subject to certain limitations, be subject to restrictions on transfer with respect to shares of Class A Common Stock and securities convertible into, or exercisable or exchangeable for, shares of Class A Common Stock for a period beginning on the Closing Date and ending on the date that is six months after the completion of the Business Combination.

The foregoing descriptions of the Registration Rights Agreement and the Lock-Up Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of such agreements, each of which is attached as an exhibit to this Schedule 13D and incorporated herein by reference.

General

The Reporting Persons acquired the securities described in this Schedule 13D in connection with the closing of the Business Combination and intend to review their investments in the Issuer on a continuing basis. Any actions the Reporting Persons might undertake may be made at any time and from time to time without prior notice and will be dependent upon the Reporting Persons’ review of numerous factors, including, but not limited to: an ongoing evaluation of the Issuer’s business, financial condition, operations and prospects; price levels of the Issuer’s securities; general market, industry and economic conditions; the relative attractiveness of alternative business and investment opportunities; and other future developments.

Subject to the terms of the Lock-Up Agreement, the Reporting Persons may acquire additional securities of the Issuer, or retain or sell all or a portion of the securities then held, in the open market or in privately negotiated transactions. In addition, the Reporting Persons, including Mr. Porter in his capacity as a director of the Issuer, may engage in discussions with management, the Board, other securityholders of the Issuer and other relevant parties, or encourage, cause or seek to cause the Issuer or such persons to consider or explore extraordinary corporate transactions, such as: a merger, reorganization or other transaction that could result in the de-listing or de-registration of the Class A Common Stock; security offerings and/or stock repurchases by the Issuer; sales or acquisitions of assets or businesses; changes to the capitalization or dividend policy of the Issuer; or other material changes to the Issuer’s business or corporate structure, including changes in management or the composition of the Board.

To facilitate their consideration of such matters, the Reporting Persons may retain consultants and advisors and may enter into discussions with potential sources of capital and other third parties. The Reporting Persons may exchange information with any such persons pursuant to appropriate confidentiality or similar agreements. The Reporting Persons will likely take some or all of the foregoing steps at preliminary stages in their consideration of various possible courses of action before forming any intention to pursue any particular plan or direction.

Other than as described above, the Reporting Persons do not currently have any plans or proposals that relate to, or would result in, any of the matters listed in Items 4(a)–(j) of Schedule 13D, although, depending on the factors discussed herein, the Reporting Persons may change their purpose or formulate different plans or proposals with respect thereto at any time.

The following sets forth, as of the date of this Schedule 13D, the aggregate number of shares of Class A Common Stock and percentage of Class A Common Stock beneficially owned by each of the Reporting Persons, as well as the number of shares of Class A Common Stock as to which each Reporting Person has the sole power to vote or to direct the vote, shared power to vote or to direct the vote, sole power to dispose or to direct the disposition of, or shared power to dispose or to direct the disposition of, as of the date hereof, based on 49,063,770 shares of Class A Common Stock outstanding following completion of the Business Combination.

The amounts reflected in the table above consists of (i) 294,118 shares of Class A Common Stock held of record by Mr. Porter and (ii) 18,755,774 shares of Class A Common Stock held of record by Three Curve LP.

As such, each of the foregoing entities and Mr. Porter may be deemed to share beneficial ownership of the securities held of record by Mr. Porter and Three Curve LP.
