As disclosed in the Prospectus, OAP IV, as one of the Pre-IPO Investors, has the right pursuant to the August 2025 Supplemental Agreement to purchase up to the number of ordinary shares of the Company offered in the Global Offering at the Offer Price that enables it to maintain its ownership interest percentage in the Company immediately prior to a qualified IPO (the “OAP IV Entitled Shares ”) (the “OAP IV Anti-Dilution Right ”). In the Global Offering, OAP IV will exercise the OAP IV Anti-Dilution Right to subscribe for additional Offer Shares at the Offer Price as a cornerstone investor in the International Offering.
