On June 19, 2026, TOP Financial Group Limited, a Cayman Islands exempted company (the “Company”), entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with certain investors (each, a “Purchaser”), pursuant to which the Company agreed to issue and sell to the Purchasers an aggregate of 6,441,012 Class A ordinary shares of the Company, par value US$0.001 per share (the “Class A Ordinary Shares”), at a purchase price of US$0.45645 per share, in a registered direct offering (the “Offering”), for aggregate gross proceeds to the Company of approximately US$2,939,999.93, before deducting estimated offering expenses of approximately US$34,500. The Securities Purchase Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company, other obligations of the parties, and termination provisions.

The Class A Ordinary Shares were offered and sold by the Company pursuant to the Company’s registration statement on Form F-3 (File No. 333-273066) (the “Registration Statement”), initially filed with the U.S. Securities and Exchange Commission (the “Commission”) on June 30, 2023 and declared effective on September 29, 2023 in accordance with the provisions of Section 8(a) of the Securities Act of 1933, as amended, and subsequently amended by post-effective amendments thereto (the most recent of which was declared effective on May 5, 2025), the base prospectus filed as part of the Registration Statement, and the prospectus supplement dated June 19, 2026. The Company is offering the Class A Ordinary Shares directly to the Purchasers, without a placement agent or underwriter. The Offering is expected to close on or about June 25, 2026, subject to the satisfaction of customary closing conditions. The Securities Purchase Agreement, the transactions contemplated thereby, and the issuance of the Class A Ordinary Shares have been approved by the Company’s board of directors.

The Company intends to use the net proceeds from the Offering for working capital and general corporate purposes.

The foregoing summary of the Securities Purchase Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the form of Securities Purchase Agreement filed as Exhibit 10.1 hereto and incorporated by reference herein. A copy of the press release issued by the Company announcing the Offering is filed as Exhibit 99.1 hereto and incorporated by reference herein.

This Report on Form 6-K, including the exhibits hereto, is hereby incorporated by reference into the Company’s registration statement on Form F-3 (File No. 333-273066), filed with the Commission, to be a part thereof from the date on which this Report is furnished, to the extent not superseded by documents or reports subsequently filed or furnished.

This report on Form 6-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact contained in this report, including statements regarding the expected closing or closings of the Offering, are forward-looking statements.
