This substantial growth underscores the traction of our branded aesthetic centers and the strategic rationale behind our transformation efforts. As our upfront investments start to yield returns we expect a more balanced growth trajectory in the coming quarters. We will continue to explore opportunities and deepen the integration across our businesses to enhance operational efficiencies and address industry challenges.”

The expansion of our center network is noticeably improving the customer experience and laying the groundwork for long-term, sustainable growth. We continued to drive operational efficiency improvements, carefully control costs, and invest in scaling and strengthening the synergies between our businesses. While the near-term environment remains dynamic, we are confident that our strategic direction will create long-term value for both our customers and shareholders.”

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 and impairment of goodwill from income/(loss) from operations, and excluding share-based compensation expenses, impairment of goodwill, impairment of long-term investment, allowance for credit loss from loans to investees, gain/(loss) on disposal of long-term investment and fair value change of long-term investment and tax effects on non-GAAP adjustments from net income/(loss) attributable to So-Young International Inc., respectively. Starting from the fourth quarter of 2024, the Company newly included impairment of long-term investment, allowance for credit loss from loans to investees, gain/(loss) on disposal of long-term investment and fair value change of long-term investment and tax effects on non-GAAP adjustments as additional adjustments in its non-GAAP financial measures, which may result in differences from previously disclosed non-GAAP figures.

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 (i) that are not expected to result in cash payments or (ii) that are non-recurring in nature or may not be indicative of the Company’s core operating results and business outlook. The use of the above non-GAAP financial measures has certain limitations. Share-based compensation expenses, the impairment of goodwill, impairment of long-term investment and allowance for credit loss from loans to investees are non-cash in nature. Gain/(loss) on disposal of long-term investment and fair value change of long-term investment are non-recurring in nature. And, in substance, both impairment of long-term investment and allowance for credit loss from loans to investees are impairment of investment. 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, impairment of goodwill, impairment of long-term investment, allowance for credit loss from loans to investees, gain/(loss) on disposal of long-term investment and fair value change of long-term investment and tax effects on non-GAAP adjustments 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.
