Non-GAAP Financial Measures

The Company uses non-GAAP net income, non-GAAP income from operations and non-GAAP basic and diluted net income per ADS, each a non-GAAP financial measure, in evaluating its operating results and for financial and operational decision-making purposes. Non-GAAP net income represents net income excluding share-based compensation expenses, amortization and depreciation of assets arising from fair value step up in business acquisitions, and tax effects on non-GAAP adjustments. Non-GAAP income from operations represents net income from operations excluding share-based compensation expenses and amortization and depreciation of assets arising from fair value step up in business acquisitions. Non-GAAP basic and diluted net income per ADS is computed using non-GAAP net income attributable to RLX Technology Inc. and the same number of ADSs used in U.S. GAAP basic and diluted net income per ADS calculation.

The Company presents these non-GAAP financial measures because they are used by the management to evaluate its operating performance and formulate business plans. The Company believes that they help identify underlying trends in its business that could otherwise be distorted by the effect of certain expenses that are included in net income. The Company also believes that the use of the non-GAAP measures facilitates investors' assessment of its operating performance, as they could provide useful information about its operating results, enhances the overall understanding of its past performance and future prospects, and allows for greater visibility with respect to key metrics used by the management in its financial and operational decision making.

The non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. The non-GAAP financial measures have limitations as analytical tools. They should not be considered in isolation or construed as an alternative to net income, basic and diluted net income per ADS or any other measure of performance or as an indicator of its operating performance. Investors are encouraged to review its historical non-GAAP financial measures to the most directly comparable U.S. GAAP measures. The non-GAAP financial measures here may not be comparable to similarly titled measures presented by other companies. Other companies may calculate similarly titled measures differently, limiting their usefulness as comparative measures to our data. The Company encourages investors and others to review its financial information in its entirety and not rely on any single financial measure.

For more information on the non-GAAP financial measures, please see the table captioned "Unaudited Reconciliation of GAAP and non-GAAP Results" set forth at the end of this press release.
