Effective as of March 18, 2026, Mango Financial Limited (“Mango Financial”) agreed to lend Cayson Acquisition Corp (the “Company”) an aggregate of $750,000. The first $125,000 of such amount was loaned to the Company and the Company deposited such amount into the trust account established by the Company in connection with its initial public offering pursuant to the Company’s Amended and Restated Memorandum and Articles of Association and trust agreement, as amended, governing the trust account in order to extend the time that the Company has to consummate an initial business combination (a “Business Combination”) for the first month extension as described below. The loan is evidenced by a promissory note (the “Note”) issued by the Company to Mango Financial. The Note bears no interest and is repayable in full upon consummation of a Business Combination.

A copy of the Note is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference. The disclosures set forth in this Item 2.03 are intended to be summaries only and are qualified in their entirety by reference to the Note.

As previously disclosed, on July 11, 2025, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Company, Mango Financial Group Limited, North Water Investment Group Holdings Limited, the parent company of Mango Financial, and Mango Temp Limited.

On March 18, 2026, the Company held an extraordinary general meeting (the “Meeting”) to approve the following resolutions:

	●	to resolve as a special resolution, that the Company’s amended and restated memorandum and articles of association as adopted by special resolution dated September 19, 2024 with effect from September 23, 2024 (the “Existing Memorandum and Articles”) be amended (the “Extension Amendment”), pursuant to which the board of directors of the Company (the “Board”) may extend the date (the “Extension”) by which the Company must consummate a business combination (as defined in the Existing Memorandum and Articles) on a monthly basis, up to twelve (12) months (or until March 23, 2027) (the “Extended Date”), unless the closing of a business combination shall have occurred prior thereto or such earlier date as shall be determined by the Board in its sole discretion, provided that the Company’s sponsors, officers, directors, affiliates or designees (collectively, the “Insiders”) lend to the Company (each a “Contribution”) an aggregate of US$125,000 for each month utilized to consummate an initial business combination, which Contributions shall be deposited by the Company into the Trust Account (as defined in the Existing Memorandum and Articles) and thereby increase the per-share redemption price paid in connection with the ultimate consummation of a business combination or the Company’s liquidation (the “Extension Proposal”);

	●	to resolve as a special resolution, that the Existing Memorandum and Articles be amended (the “Redemption Limitation Amendment”) to remove the limitation (the “Redemption Limitation”) that the Company shall not redeem public shares to the extent that such redemptions would cause the Company’s net tangible assets to be less than $5,000,001 (the “Redemption Limitation Proposal”);

	●	to resolve as an ordinary resolution, that the Investment Management Trust Agreement, dated as of September 19, 2024 (the “Trust Agreement”), entered into by and between Continental Stock Transfer & Trust Company, as trustee (the “Trustee”), and the Company be amended (the “Trust Amendment”) to change the amount of funds to be deposited into the trust account in connection with extending the time to complete an initial business combination as described in the Extension Proposal (the “Trust Amendment Proposal”); and

	●	to resolve as an ordinary resolution, that the adjournment of the Extraordinary General Meeting to a later date or dates, if necessary, to approve the Extension Proposal, the Redemption Limitation Proposal and the Trust Amendment Proposal be approved (the “Adjournment Proposal”).

An aggregate of 6,596,416 ordinary shares of the Company, which represented a quorum of the outstanding ordinary shares entitled to vote as of the record date of February 18, 2026, were represented in person or by proxy at the Meeting.

The Company’s shareholders voted on the proposals at the Meeting, which were approved as follows:
