Item 1.01. Entry into a Definitive Material Agreement.

On October 23, 2026, Cayson Acquisition Corp (the “Company”) entered into a Strategic Cooperation and Services Agreement (the “Agreement”) with Prisma Global Holding Limited (“Prisma”), a Hong Kong-based entity engaged in corporate brand management, overseas listing and cross-border capital markets advisory services, investor relations and business development advisory services. Prisma is led by its Founder and Executive Chairman, Heming Tan (Sam Tan). Pursuant to the Agreement, Prisma has agreed to assist the Company in obtaining loans of up to $1,000,000 for working capital purposes prior to the consummation of an initial business combination (the “Working Capital Financing Services”). The terms of any loans will be set forth in the promissory notes executed in connection with any agreement with a lender. Additionally, Prisma has agreed to introduce the Company to potential sources of financings of up to $18,000,000 to be consummated simultaneously with the consummation of an initial business combination (the “PIPE Introduction Services”). In consideration of the Working Capital Financing Services, the Company will pay Prisma a fee of 10% for each loan committed to the Company, up to a maximum of $100,000 for any loans made to the Company. For the PIPE Introduction Services, the Company will pay a fee to be mutually agreed between the Company and Prisma prior to execution of any definitive documents for the financings. The Company has also agreed to reimburse Prisma for certain expenses in connection with its services under the Agreement in an amount equal to 5% of the aggregate loan amounts actually funded to the Company, up to a maximum of $50,000.

The foregoing description of the Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

This Current Report on Form 8-K shall not constitute an offer to sell or a solicitation of an offer to buy any securities of the Company, nor shall there be any sale of any securities of the Company in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.

Item 8.01. Other Events.

As previously reported, on September 23, 2026, the Company held an extraordinary general meeting (the “Meeting”) to approve, among other matters, a proposal to amend 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 and amended on March 18, 2026 (the “Existing Memorandum and Articles”) to allow the Company’s Board to extend the date (the “Extension”) by which the Company had to consummate a business combination (as defined in the Existing Memorandum and Articles) on a monthly basis, up to twelve (12) months (or until September 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$60,000 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. On October 26, 2026, the Insiders deposited the Contribution for the second month of the Extension.

The Company is continuing to seek to attempt to consummate an initial business combination.
