Explanation of Responses:

( 1 )Upon the completion of the Business Combination, the shares of Class B Common Stock issued at the Issuer's (formerly, Power & Digital Infrastructure Acquisition II Corp.) initial public offering were automatically converted into shares of the Issuer's Class A Common Stock on a one-to-one basis. ( 2 )XPDI Sponsor II LLC (the "Sponsor") is controlled by its managing members, Transition Equity Partners, LLC ("TEP") and XMS XPDI Sponsor II Holdings, LLC ("XMS XPDI Holdings"). Patrick C. Eilers is the managing member of TEP, and Theodore J. Brombach and John Yogi Spence are the managing members of XMS XPDI Holdings. Accordingly, all of the shares held by the Sponsor may be deemed to be beneficially held by each of the foregoing individuals and entities. Each such person disclaims beneficial ownership of these securities, except to the extent, if any, of their pecuniary interest therein. ( 3 )The reporting persons are the managing members of XMS MT Holdings LLC. As a result, each of the reporting persons may be deemed to share beneficial ownership over the securities held by XMS MT Holdings LLC, but disclaims beneficial ownership of these securities, except to the extent, if any, of his pecuniary interest therein. ( 4 )Represents securities received as part of the Issuer's business combination, in connection with that certain Agreement and Plan of Merger, dated as of June 5, 2023 (the "Merger Agreement"), by and between the Issuer (formerly, Power & Digital Infrastructure Acquisition II Corp.), XPDB Merger Sub, LLC and Montana Technologies LLC ("Legacy Montana"), pursuant to which the common units of Legacy Montana automatically converted into newly issued shares of Class A Common Stock.
