INFORMATION CONTAINED IN THIS FORM 6-K REPORT

As previously disclosed on the Report on Form 6-K filed with the Securities and Exchange Commission by WF International Limited, a Cayman Islands exempted company (the “Company”) on November 10, 2025, on November 4, 2025, the Company and The Benchmark Company, LLC and Axiom Capital Management, Inc. (collectively, the “Placement Agents”) entered into a placement agency agreement (the “Placement Agency Agreement”), pursuant to which the Placement Agents are entitled to a right of first refusal (the “ROFR”), as set forth in Section 2(D) of the Placement Agency Agreement, to act as investment bankers, book runners, or placement agents (i) for each and every public and private equity and debt offerings of the Company and (ii) each proposed or contemplated merger or acquisition transaction whereby the Company would be merged into or acquired by another company or entity for a period of twelve months following November 6, 2025, subject to certain terms and limitations pursuant to the Placement Agency Agreement.
