RLX Technology AnnouncesUnaudited First Quarter 2026 Financial Results

SHENZHEN, May 20, 2026 - RLX Technology Inc. (“RLX Technology” or the “Company”) (NYSE: RLX), a leading global branded e-vapor company, today announced its unaudited financial results for the first quarter ended March 31, 2026.

First Quarter 2026 Financial Highlights

·	Net revenues were<br> RMB1,585.8 million (US$229.9 million) in the first quarter of 2026, increasing by 96.2% from<br> RMB808.3 million in the same period of 2025.
·	Gross margin was 31.8% in the<br> first quarter of 2026, compared with 28.6% in the same period of 2025.
·	Non-GAAP income from operations^1^ was RMB310.3 million (US$45.0 million) in the first<br> quarter of 2026, increasing by 187.9% from RMB107.8 million in the same period of 2025.
·	U.S. GAAP net income was RMB294.2 million (US$42.6 million) in the first quarter of 2026, increasing<br> by 32.1% from RMB222.7 million in the same period of 2025.
·	Non-GAAP net income^1^ was RMB357.3 million (US$51.8 million) in the first quarter of<br> 2026, increasing by 41.4% from RMB252.7 million in the same period of 2025.

“We began this year with robust first-quarter results, underpinned by a highly scalable global ecosystem and our ability to capture emerging market opportunities,” said Ms. Ying (Kate) Wang, Co-founder, Chairperson, and Chief Executive Officer of RLX Technology. “We continued to accelerate our international expansion and broaden our global operations. Notably, we refined our user-first approach through highly localized strategies and deep engagement with trusted regional business partners to ensure superior product-market fit, strengthening our global competitiveness. We also integrated our R&D, manufacturing, and commercial operations into our Super Factory, a cutting-edge hub that is driving greater supply chain efficiencies while allowing us to seamlessly meet rising demand. Looking ahead, we will build on this momentum by focusing on innovative and user-centric products, strengthening our distribution and retail capabilities, and deepening our presence in Europe. Our uncompromising commitment to responsibility and adult-user harm reduction remains the core engine of our long-term growth.”

Mr. Chao Lu, Chief Financial Officer of RLX Technology, commented, “In the first quarter, we delivered rapid top-line growth, with net revenues increasing to RMB1.59 billion, up 96.2% year over year and 38.9% quarter over quarter. This acceleration was fueled by momentum across our international operations, accretion from our newly acquired European entity, and steady progress in our mainland China business, as well as a one-time impact from changes in China’s export policies. The operating leverage from this growth translated into significant profitability, with non-GAAP operating income surging 187.9% to RMB310.3 million. We also structurally enhanced our margin profile through strict cost discipline and scale efficiencies across our comprehensive, broadly appealing product portfolio. Supported by a strong balance sheet, we enter the remainder of the year with the financial flexibility to execute our next phase of growth, accelerate our market penetration in Asia and Europe, and generate sustainable, long-term returns for our shareholders.”

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 the 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, enhance the overall understanding of its past performance and future prospects, and allow 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 against 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.
