The information in this Item 7.01, including the related exhibits, 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 the SPAC under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language in such filings. This Current Report will not be deemed an admission as to the materiality of any information contained in this Item 7.01.

Additional Information and Where to Find It

In connection with the proposed Business Combination, the SPAC and the Company intend to file relevant materials with the Securities and Exchange Commission (the “SEC”), including a registration statement on Form F-4 (the “F-4 Registration Statement”) which will include a proxy statement to solicit approval of certain proposals regarding the Business Combination by the SPAC’s shareholders (the “Proxy Statement”) and a prospectus covering the issuance of the Company Class A Ordinary Shares to be issued in the Merger (the “Prospectus”). After the F-4 Registration Statement is declared effective by the SEC, the definitive Proxy Statement and Prospectus and other relevant documents will be mailed to the shareholders of the SPAC as of the record date established for voting on the proposed Business Combination and will contain important information about the proposed Business Combination and related matters. Shareholders of the SPAC and other interested persons are advised to read, when available, these materials (including any amendments or supplements thereto) and any other relevant documents in connection with the SPAC’s solicitation of proxies for the meeting of SPAC shareholders to be held to approve, among other things, the proposed Business Combination, because they will contain important information about the SPAC, the Company and the proposed Business Combination. Shareholders will also be able to obtain copies of the preliminary Proxy Statement and Prospectus, the definitive Proxy Statement and Prospectus and other relevant materials in connection with the transaction without charge, once available, at the SEC’s website at www.sec.gov or by directing a request to: Cayson Acquisition Corp, c/o Yawei Cao, 420 Lexington Avenue, Suite 2446, New York, NY 10170, Telephone: (203) 998-5540.

Participants in the Solicitation

The SPAC and its respective directors and executive officers may be deemed participants in the solicitation of proxies from the SPAC shareholders in connection with the proposed Business Combination. The SPAC shareholders and other interested persons may obtain, without charge, more detailed information regarding the directors and officers of the SPAC as reflected of the SPAC’s final prospectus of September 20, 2024, in connection with the SPAC’s initial public offering, as filed with the SEC. Information regarding the persons who may, under SEC rules, be deemed participants in the solicitation of proxies to the SPAC shareholders in connection with the proposed Business Combination will be set forth in the proxy statement/prospectus for the proposed Business Combination when available. Additional information regarding the interests of participants in the solicitation of proxies in connection with the proposed Business Combination will be included in the Proxy Statement and Prospectus to be included in the F-4 Registration Statement and filed with the SEC. You may obtain free copies of these documents as described in the preceding paragraph.

The Company and its respective directors and executive officers may also be deemed to be participants in the solicitation of proxies from the SPAC shareholders in connection with the proposed Business Combination. A list of the names of such directors and executive officers and information regarding their interests in the proposed Business Combination will be included in the Proxy Statement and Prospectus for the proposed Business Combination when available.

No Solicitation or Offer

This communication shall neither constitute an offer to sell nor the solicitation of an offer to buy any securities, or the solicitation of any proxy, vote, consent or approval in any jurisdiction in connection with the Business Combination, nor shall there be any sale of securities in any jurisdiction in which the offer, solicitation or sale would be unlawful prior to any registration or qualification under the securities laws of any such jurisdictions. This communication is restricted by law; it is not intended for distribution to, or use by any person in, any jurisdiction where such distribution or use would be contrary to local law or regulation.

Forward-Looking Statements Legend

This communication contains forward-looking statements. The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. All statements other than statements of historical facts contained in this communication, including statements regarding the expected timing and structure of the Business Combination, the ability of the parties to complete the Business Combination, the expected benefits of the Business Combination, the tax consequences of the Business Combination, the amount of gross proceeds expected to be available to the SPAC after the Closing and giving effect to any redemptions by the SPAC shareholders, the Company’s future results of operations and financial position, business strategy and its expectations regarding the application and commercialization of its products. These forward-looking statements are not guarantees of future performance, conditions or results, and involve a number of known and unknown risks, uncertainties, assumptions and other important factors, many of which are outside the control of the SPAC and the Company, that could cause actual results or outcomes to differ materially from those discussed in the forward-looking statements. Important factors, among others, that may affect actual results or outcomes include, but are not limited to: the risk that there will be issues with the integration of cryptocurrency elements in the financial operations of Mango Financial; the risk that the transactions may not be completed in a timely manner or at all, which may adversely affect the price of the SPAC’s securities; the risk that the SPAC shareholder approval of the Business Combination is not obtained; the inability to realize the anticipated benefits of the Business Combination, which may be affected by, among other things, the amount of funds available in the Trust Account following any redemptions by the SPAC shareholders; the failure to receive certain governmental and regulatory approvals; the occurrence of any event, change or other circumstance that could give rise to the termination of the Merger Agreement; changes in general economic or business conditions; the outcome of litigation related to or arising out of the Business Combination, or any adverse developments therein or delays or costs resulting therefrom; the effect of the announcement or pendency of the transactions on the SPAC’s or the Company’s respective business relationships, operating results, and businesses generally; the ability of the Company to meet Nasdaq’s listing standards in connection with and following the consummation of the Business Combination; costs related to the Business Combination; that the price of the Company’s securities may be volatile due to a variety of factors, including the SPAC’s or the Company’s inability to implement their respective business plans or meet or exceed their financial projections and changes in the combined capital structure; the ability to implement business plans, forecasts, and other expectations after the completion of the Business Combination, and identify and realize additional opportunities; and the ability of the Company to implement its strategic initiatives.

The foregoing list of 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 SPAC’s registration statement on Form S-1 (File No. 333-280564), in the F-4 Registration Statement (once available), and in the other documents filed or that may be filed by the SPAC or the Company from time to time with the SEC following the date hereof. These filings 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. 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 the SPAC assumes no obligation and does not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise.

The SPAC does not give any assurance that the SPAC or the Company will achieve their expectations.
