Core Viewpoint - So-Young International Inc. is postponing the effective date for the planned change in the American depositary shares (ADS) ratio, which was initially set for June 30, 2025 [2][3]. Group 1: ADS Ratio Change - The company intends to change the ADS ratio from thirteen ADSs representing ten Class A ordinary shares to one ADS representing fifteen Class A ordinary shares [2]. - The decision to delay the ADS ratio change is due to the need for additional time to finalize preparations [2]. - An updated timeline for the ADS ratio change will be announced in the future [2]. Group 2: Impact on ADS Holders - The ADS ratio change will function similarly to a proportional reverse ADS split, with no changes to the Class A ordinary shares [3]. - ADS holders will not need to take any action; the exchange of old ADSs for new ADSs will occur automatically [3]. - Fractional new ADSs will not be issued; instead, fractional entitlements will be aggregated and sold, with net cash proceeds distributed to ADS holders [3]. Group 3: Price Expectations - Following the ADS ratio change, the ADS price is expected to increase proportionally, although there is no assurance that the post-change price will match or exceed the proportional price based on the pre-change price [4]. Group 4: Company Overview - So-Young International Inc. is a leading aesthetic treatment platform in China, connecting consumers with online services and offline treatments [5]. - The company offers access to aesthetic treatments through its online platform and branded aesthetic centers, providing curated treatment information and facilitating online reservations [5]. - With strong brand recognition and an efficient supply chain, So-Young is positioned for long-term growth in the medical aesthetic value chain [5].
