Entry into Material Definitive Agreement 

On June 1, 2026, China SXT Pharmaceuticals, Inc. (the “Company”) entered into a certain sales agreement (the “Sales Agreement”) with Univest Securities, LLC (the “Sales Agent”) to issue and sell the Company’s Class A ordinary shares, with no par value per share (the “Class A Ordinary Shares”), in an aggregate offering amount of up to $100,000,000 through an at-the-market offering, under which the Sales Agent will act as sales agent and/or principal.

Subject to the terms and conditions of the Sales Agreement, the Sales Agent has agreed to use its commercially reasonable efforts, consistent with its normal sales and trading practices to place the Class A Ordinary Shares, subject to, and in accordance with the information specified in a written notice from the Company, unless the sale of the Class A Ordinary Shares described therein has been suspended, cancelled or otherwise terminated.

The Sales Agent’s obligation to sell Class A Ordinary Shares under the Sales Agreement is subject to satisfaction of certain conditions, and other customary closing conditions. The sales, if any, under the Sales Agreement will be made by any method permitted by law deemed to be an “at-the-market offering” as defined in Rule 415 under the Securities Act of 1933, including, without limitation, sales made directly on the Nasdaq Capital Market, on any other existing trading market for the Class A Ordinary Shares or to or through a market maker.

The Sales Agreement provides that the commission payable to the Sales Agent for sales of Class A Ordinary Shares with respect to which the Sales Agent acts as sales agent shall be equal to 3.00% of the gross proceeds of such sale. The Company also agreed to reimburse the Sales Agent $0.003 per share sold under the Sales Agreement as trading fee and exchange fee reimbursement and certain other expenses, subject to the limitations set forth in the Sales Agreement.

The Sales Agreement contains customary representations and warranties of the parties and indemnification and contribution provisions under which the Company and the Sales Agent have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act. The Sales Agent and the Company have the right, by giving written notice as specified in the Sales Agreement, to terminate the Sales Agreement.

The offering has been registered under the Securities Act pursuant to the Company’s shelf registration statement on Form F-3 (Registration No. 333-291428), as supplemented by the prospectus supplement dated June 1, 2026, relating to the sale of up to $100,000,000 Class A Ordinary Shares.

A copy of the Sales Agreement is attached as Exhibit 1.1 hereto and is incorporated herein by reference. The foregoing description of the Sales Agreement does not purport to be complete and is qualified in its entirety by reference to such exhibit.

A copy of the opinion of Appleby, as BVI counsel to the Company, relating to the validity of the securities to be issued in accordance with the Sales Agreement is filed herewith as Exhibit 5.1 and is incorporated by reference herein.

This Report shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the Class A Ordinary Shares 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.
