Item 5.08 Shareholder Director Nominations.

On September 17, 2025, the board of directors of XTI Aerospace, Inc. (the “Company”) set November 14, 2025 as the date of the Company’s 2025 Annual Meeting of Stockholders (the “2025 Annual Meeting”). The 2025 Annual Meeting will be a virtual meeting. Stockholders of record at the close of business on September 17, 2025 will be entitled to notice of and to vote at the 2025 Annual Meeting. Because the date of the 2025 Annual Meeting is more than 30 days before the anniversary date of the 2024 Annual Meeting of Stockholders, the Company is providing the due date for submission of any qualified stockholder proposal or qualified stockholder nominations.

Stockholders of the Company who wish to have a proposal considered for inclusion in the Company’s proxy materials for the 2025 Annual Meeting pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), must ensure that such proposal is received by the Company’s Secretary at its principal executive offices at the address set forth above on or before the close of business on September 27, 2025, which the Company has determined to be a reasonable time before it expects to begin to print and send its proxy materials. Any such proposal must also meet the requirements set forth in the rules and regulations of the Securities and Exchange Commission in order to be eligible for inclusion in the proxy materials for the 2025 Annual Meeting.

In addition, in accordance with the requirements contained in the Company’s bylaws, stockholders of the Company who wish to bring business before the 2025 Annual Meeting outside of Rule 14a-8 of the Exchange Act or to nominate a person for election as a director must ensure that written notice of such proposal (including all information specified in the Company’s bylaws) is received by the Company’s Secretary at the Company’s principal executive offices at the address set forth above no later than the close of business on September 27, 2025. Any such proposal must meet the requirements set forth in the Company’s bylaws to be brought before the 2025 Annual Meeting.

In addition, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act by September 27, 2025, which is the tenth calendar day following the date of this Current Report on Form 8-K publicly announcing the date of the 2025 Annual Meeting.
