Entry into a Material Definitive Agreement.

On August 19, 2026, WF International Limited, a Cayman Islands exempted company (the “Company” or “WF”), entered into a Share Purchase Agreement (the “Share Purchase Agreement”) with the certain investors (collectively, the “Purchasers”), pursuant to which the Company agreed to sell and issue to the Purchasers, in a registered direct offering (the “Offering”), 111,333 ordinary shares, par value $0.00001 per share, of the Company (the “Shares”), at an offering price of $1.50 per share.

The Offering is expected to close on August 21, 2026. The Shares are offered and sold pursuant to the Company’s shelf registration statement on Form F-3 (File No. 333-333-295778), which was initially filed with the Securities and Exchange Commission (the “SEC”) on May 27, 2026, and was declared effective by the SEC on May 27, 2026 (the “Registration Statement”), the base prospectus dated May 27, 2026 contained in the Registration Statement, and a prospectus supplement dated August 20, 2026 filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”).

The Company expects to receive gross proceeds from the Offering of approximately $166,999.50, before deducting estimated offering expenses payable by the Company. The Company intends to use the net proceeds from the Offering for general corporate purposes.

The Share Purchase Agreement contains customary conditions to closing, representations and warranties of the Company and the Purchasers, and termination rights of the parties, as well as certain indemnification obligations of the Company and ongoing covenants for the Company.

A copy of the opinion of Maples and Calder (Hong Kong) LLP, Cayman counsel to the Company, relating to the legality of the Shares is filed as Exhibit 5.1 to this Report on Form 6-K (this “Report”) and is incorporated by reference into the Registration Statement.
