Phase* (Operating duration)	Number<br> of<br> Centers		Revenue<br> <br> (RMB)		Average<br> Revenue per<br> Center (RMB)		Average<br> Center Age<br> (Month)
Ramp-up (0-3 months)		10		9,537,000		954,000		1.0

* For the purposes of this table, “Phase” refers to the length of time since commencement of actual operations rather than the legal establishment or registration date of a branded aesthetic center. In cases where a center has been relocated, merged, or its team and customer base transferred to another location, the operating duration of the branded aesthetic center is calculated from the commencement date of the predecessor center’s operations. Periods during which a center is temporarily closed and not conducting external operations (e.g., due to renovation or other suspensions of business) are excluded from the calculation of operating duration. Branded aesthetic centers that have been converted to other uses or are no longer within the reporting scope are excluded from the statistics.

Mr. Xing Jin, Co-Founder and Chief Executive Officer of So-Young, commented, “In the third quarter, our branded aesthetic centers continued to deliver strong, high-quality growth with aesthetic treatment services revenues once again exceeding our guidance range. Our network comprises of 39 centers nationwide by the end of September, underscoring the growing trust in the So-Young Clinic brand and our continued progress toward making high-quality aesthetic treatments more accessible and affordable. By deepening integration with our supply chain and upholding industry-leading medical and compliance standards, we are redefining how value is created and shared, ensuring consumers receive transparent pricing and safe, standardized services. Looking ahead, we will continue to scale with discipline, enhance operational efficiency, and drive greater transparency and professionalism across the medical aesthetics industry.”

Mr. Hui Zhao, Chief Financial Officer of So-Young, added, “In the third quarter, we continued to deliver healthy financial results, driven by consistent execution across our aesthetic center network. As we rapidly approach our year-end target of 50 centers, we are seeing clear and tangible improvements in operating efficiency and cost structure. As we move into the next phase of expansion, we will continue to invest prudently and allocate resources with discipline to support sustainable growth and long-term value creation.”

The above outlook is based on the current market conditions and reflects the Company’s preliminary estimates of market and operating conditions, as well as customer demand, which are all subject to change.

Non-GAAP Financial Measures

To supplement the financial measures prepared in accordance with generally accepted accounting principles in the United States, or GAAP, this press release presents non-GAAP income/(loss) from operations and non-GAAP net income/(loss) attributable to So-Young International Inc. by excluding share-based compensation expenses from income/(loss) from operations and net income/(loss) attributable to So-Young International Inc., respectively. The Company believes these non-GAAP financial measures are important to help investors understand the Company’s operating and financial performance, compare business trends among different reporting periods on a consistent basis and assess the Company’s core operating results, as they exclude certain expenses that are not expected to result in cash payments. The use of the above non-GAAP financial measures has certain limitations. Share-based compensation expenses are non-cash in nature. All these are not reflected in the presentation of the non-GAAP financial measures, but should be considered in the overall evaluation of the Company’s results. The Company compensates for these limitations by providing the relevant disclosure of its share-based compensation expenses in the reconciliations to the most directly comparable GAAP financial measures, which should be considered when evaluating the Company’s performance. These non-GAAP financial measures should be considered in addition to financial measures prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, financial measures prepared in accordance with GAAP. Reconciliation of each of these non-GAAP financial measures to the most directly comparable GAAP financial measure is set forth at the end of this release.
