OSR Health, Inc.

Item 1.01. Entry into a Material Definitive Agreement. As previously disclosed, OSR Health, Inc. (the “Company”), its wholly owned subsidiary Vaximm AG, and BCM Europe AG (“BCME”) are parties to a Global Exclusive License Agreement for VXM01, effective April 29, 2026 (the “License Agreement”), under which the Company holds a put option (the “Equity Option”) to require BCME to purchase up to $15,000,000 of the Company’s common stock. On October 15, 2026, the parties entered into Amendment No. 1 to the License Agreement (the “Amendment”), which adds the following new Section 6.10: 6.10 Alternative Settlement (Convertible Note Option) (a) Acknowledgment. The Parties acknowledge that the delisting determination issued by the Nasdaq Staff on August 19, 2026 is a material subsequent development affecting settlement of the Equity Option. The rights in this Section 6.10 apply whether or not that determination is later stayed, extended, conditionally granted or followed by relisting. (b) Election. OSRH may, by written notice to BCME (the “Note Election Notice”), change all or part of the unexercised Equity Option into a Convertible Note Option, whereby OSRH, or its affiliate, shall issue Convertible Notes in an aggregate principal amount of up to $15,000,000 (less amounts previously settled under the Equity Option), and BCME shall purchase, or shall effectuate a third party to purchase, such Convertible Notes at par. The Equity Option terminates as to the elected amount. (c) Conversion prices. The Convertible Notes shall be issued in four tranches of $3,750,000 each, convertible into OSRH common stock at fixed conversion prices of approximately $2.00, $3.00, $4.00 and $5.00 per share, respectively. If the Minimum Price (as defined in Nasdaq Rule 5635) on the date of the purchase commitment exceeds the conversion price of any tranche, that tranche’s conversion price is the Minimum Price. Conversion prices are not subject to reset. (d) Purchaser and closing certainty. BCME has identified the purchaser and shall deliver the purchaser’s binding commitment to purchase the Convertible Notes with or before the Note Election Notice. Closing occurs no fewer than twenty (20) Business Days after the Note Election Notice. If the purchase does not close within ten (10) Business Days after the scheduled closing date, the Note Election Notice is deemed withdrawn, the Equity Option is reinstated in full as to the elected amount, and the Exercise Window is extended by the period elapsed. BCME’s obligations under the reinstated Equity Option are unaffected. The foregoing description of the Amendment is qualified in its entirety by reference to the full text of the Amendment, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
