Item 7.01. Regulation FD Disclosure.

As previously announced, on November 7, 2025, Cantor Equity Partners III, Inc., a Cayman Islands exempted company (“CAEP”), AIR Limited, a private limited company incorporated under the laws of Jersey (the “Company”), AIR Holdings Limited, a private limited company incorporated under the laws of Jersey (“Pubco”), Genesis Cayman Merger Sub Limited, a Cayman Islands exempted company, and Genesis Jersey Merger Sub Limited, a private limited company incorporated under the laws of Jersey, entered into a business combination agreement (the “Business Combination Agreement”) with respect to a proposed business combination among the parties in accordance with the Business Combination Agreement (the “Business Combination” and, together with the other transactions contemplated by the Business Combination Agreement and the Ancillary Agreements, the “Transactions”). Capitalized terms used in this Current Report on Form 8-K (this “Report”) but not otherwise defined herein have the meanings given to them in the Business Combination Agreement.

Furnished as Exhibit 99.1 hereto and incorporated by reference is an updated investor presentation that CAEP and the Company have prepared for use in connection with the Business Combination.

The information in this Item 7.01, including Exhibit 99.1, is furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to liabilities under that section, and shall not be deemed to be incorporated by reference into the filings of CAEP under the Securities Act of 1933, as amended (the “Securities Act”) or the Exchange Act, regardless of any general incorporation language in such filings. This Current Report on Form 8-K will not be deemed an admission as to the materiality of any of the information in this Item 7.01, including Exhibit 99.1.

Additional Information and Where to Find It

Pubco and CAEP intend to prepare, and Pubco intends to file with the SEC, a registration statement on Form F-4 (the “Registration Statement”), which will include a preliminary proxy statement of CAEP and a prospectus (the “Proxy Statement/Prospectus”) in connection with the Transactions. The definitive proxy statement and other relevant documents will be mailed to shareholders of CAEP as of a record date to be established for a meeting of CAEP shareholders for voting on the Transactions and other matters as described in the Proxy Statement/Prospectus. CAEP and/or Pubco will also file other documents regarding the Transactions with the SEC. This Report does not contain all of the information that should be considered concerning the Transactions and is not intended to form the basis of any investment decision or any other decision in respect of the Transactions. BEFORE MAKING ANY VOTING OR INVESTMENT DECISION, SHAREHOLDERS OF CAEP AND OTHER INTERESTED PARTIES ARE URGED TO READ, WHEN AVAILABLE, THE PRELIMINARY PROXY STATEMENT/PROSPECTUS, AND AMENDMENTS THERETO, AND THE DEFINITIVE PROXY STATEMENT/PROSPECTUS AND ALL OTHER RELEVANT DOCUMENTS FILED OR THAT WILL BE FILED WITH THE SEC IN CONNECTION WITH CAEP’S SOLICITATION OF PROXIES FOR THE EXTRAORDINARY GENERAL MEETING OF ITS SHAREHOLDERS TO BE HELD TO APPROVE THE TRANSACTIONS AND OTHER MATTERS AS DESCRIBED IN THE PROXY STATEMENT/PROSPECTUS BECAUSE THESE DOCUMENTS WILL CONTAIN IMPORTANT INFORMATION ABOUT CAEP, PUBCO, THE COMPANY AND THE TRANSACTIONS. Investors and security holders will also be able to obtain copies of the Registration Statement and the Proxy Statement/Prospectus and all other documents filed or that will be filed with the SEC by CAEP and Pubco, without charge, once available, on the SEC’s website at www.sec.gov or by directing a request to: Cantor Equity Partners III, Inc., 110 East 59th Street, New York, NY 10022; e-mail: CantorEquityPartners@cantor.com, or upon written request to AIR Limited, via email at investor@air.global, respectively.

NEITHER THE SEC NOR ANY STATE SECURITIES REGULATORY AGENCY HAS APPROVED OR DISAPPROVED THE TRANSACTIONS DESCRIBED HEREIN, PASSED UPON THE MERITS OR FAIRNESS OF THE TRANSACTIONS OR ANY RELATED TRANSACTIONS OR PASSED UPON THE ADEQUACY OR ACCURACY OF THE DISCLOSURE IN THIS REPORT. ANY REPRESENTATION TO THE CONTRARY CONSTITUTES A CRIMINAL OFFENSE.

Participants in the Solicitation

CAEP, Pubco, the Company and their respective directors, executive officers, and certain of their shareholders and other members of management and employees may be deemed under SEC rules to be participants in the solicitation of proxies from CAEP’s shareholders in connection with the Transactions. A list of the names of such persons, and information regarding their interests in the Transactions and their ownership of CAEP’s securities are, or will be, contained in CAEP’s filings with the SEC, including the final prospectus of CAEP dated as of June 25, 2025 and filed by CAEP with the SEC on June 26, 2025 (the “IPO Prospectus”). Additional information regarding the interests of the persons who may, under SEC rules, be deemed participants in the solicitation of proxies of CAEP’s shareholders in connection with the Transactions, including the names and interests of CAEP’s, Pubco’s and the Company’s directors and executive officers, will be set forth in the Registration Statement and Proxy Statement/Prospectus, which is expected to be filed by Pubco, the Company and CAEP, as applicable with the SEC. Investors and security holders may obtain free copies of these documents as described above.

Forward-Looking Statements

This Report contains certain forward-looking statements within the meaning of the U.S. federal securities laws with respect to the Transactions involving Pubco, CAEP and the Company, including expectations, intentions, hopes, beliefs, prospects, financial results and plans regarding Pubco, the Company, CAEP and the Transactions, statements regarding the anticipated benefits and timing of the completion of the Transactions, entry into certain agreements subsequent to the entry into the Business Combination Agreement, the satisfaction of closing conditions to the Transactions, objectives of management for future operations of Pubco, pro forma ownership of Pubco, the upside potential and opportunity for investors, investor benefits, regulatory conditions, competitive position, technological and market trends, future financial condition and performance and expected financial impacts of the Transactions, the satisfaction of closing conditions to the Transactions and the level of redemptions of CAEP’s public shareholders, and Pubco’s and the Company’s expectations, intentions, strategies, assumptions or beliefs about future events, results of operations or performance or that do not solely relate to historical or current facts. These forward-looking statements generally are identified by the words “believe,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,” “opportunity,” “potential,” “plan,” “may,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result,” and similar expressions. Forward-looking statements are predictions, projections and other statements about future events or conditions that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this Report, including, but not limited to: the risk that the Transactions may not be completed in a timely manner or at all, which may adversely affect the price of CAEP’s securities; the risk that the Transactions may not be completed by CAEP’s business combination deadline; the failure by the parties to satisfy the conditions to the consummation of the Transactions, including the approval of CAEP’s shareholders; failure to realize the anticipated benefits of the Transactions; the level of redemptions of CAEP’s public shareholders which may reduce the public float of, reduce the liquidity of the trading market of, and/or maintain the quotation, listing, or trading of the CAEP Class A ordinary shares or Pubco’s ordinary shares; the lack of a third-party fairness opinion in determining whether or not to pursue the Transactions; the failure of Pubco to obtain or maintain the listing of its securities on any securities exchange after closing of the Transactions; costs related to the Transactions and as a result of becoming a public company; changes in business, market, financial, political and regulatory conditions; risks relating to Pubco’s anticipated operations and business; risks related to increased competition in the industries in which Pubco will operate; risks that after consummation of the Transactions, Pubco experiences difficulties managing its growth and expanding operations; challenges in implementing Pubco’s business plan including due to operational challenges, significant competition and regulation; being considered to be a “shell company” by any stock exchange on which Pubco’s ordinary shares will be listed or by the SEC, which may impact Pubco’s ability to list Pubco’s ordinary shares and restrict reliance on certain rules or forms in connection with the offering, sale or resale of securities; the outcome of any potential legal proceedings that may be instituted against Pubco, CAEP or others following announcement of the Transactions, and those risk factors discussed in documents that Pubco and/or CAEP filed, or that will be filed, with the SEC.

The foregoing list of risk factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of the IPO Prospectus, CAEP’s Quarterly Reports on Form 10-Q, and the Registration Statement that will be filed by Pubco and the Company and the Proxy Statement/Prospectus contained therein, and other documents filed by CAEP and Pubco from time to time with the SEC. These filings do or will 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. There may be additional risks that none of CAEP, the Company and Pubco presently know or that CAEP, the Company and Pubco currently believe are immaterial that could also cause actual results to differ 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 none of CAEP, the Company and Pubco assumes any obligation and do not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. None of CAEP, the Company and Pubco gives any assurance that any of CAEP, the Company or Pubco will achieve its expectations. The inclusion of any statement in this Report does not constitute an admission by CAEP, the Company or Pubco or any other person that the events or circumstances described in such statement are material.
