SHENZHEN, May 16, 2025 /PRNEWSWIRE/ - 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, 2025.

F****irstQuarter 2025 Financial Highlights

·	Net revenues were RMB808.3 million (US$111.4 million) in the first quarter of 2025, compared with<br>RMB551.6 million in the same period of 2024.
·	Gross margin was 28.6% in the first quarter of 2025, compared with 25.9% in the same period of<br>2024.
---	---
·	U.S. GAAP net income was RMB222.7 million (US$30.7 million) in the first quarter of 2025, compared<br>with RMB132.6 million in the same period of 2024.
---	---

“We were pleased to deliver impressive results in the first quarter of 2025 amid a challenging macro environment,” commented Ms. Ying (Kate) Wang, Co-founder, Chairperson of the Board of Directors, and Chief Executive Officer of RLX Technology. “E-vapor exports from China declined year over year in the first quarter due to bans on disposable products, excise taxes and an evolving regulatory environment, factors that will continue to impact the e-vapor industry as a whole throughout 2025. Stricter regulations are also driving shifts in market dynamics, with a transition to larger-volume e-liquid products emerging as a global trend, reflecting users’ demand for convenient and cost-effective products. As a trusted brand with leading product R&D capabilities, robust inventory management systems, and a diverse global presence, RLX is well-positioned to navigate the ever-changing regulatory landscape and outperform the market, meeting the needs of adult smokers worldwide.”

Mr. Chao Lu, Chief Financial Officer of RLX Technology, added, “Our effective strategy and ongoing international expansion continued to support sustainable, profitable growth in the first quarter, driving a 46.5% year-over-year increase in net revenues to RMB808.3 million. Notably, our non-GAAP income from operations^1^ also surged to RMB105.8 million thanks to our impactful cost optimization initiatives and operating leverage. While we expect regulatory and market challenges to persist, we remain confident in our ability to consistently propel high-quality business development and enhance shareholder value through strong strategic execution.”

First Quarter 2025 Financial Results

Netrevenues were RMB808.3 million (US$111.4 million) in the first quarter of 2025, compared with RMB551.6 million in the same period of 2024. The increase was primarily due to our international expansion.

Grossprofit was RMB231.0 million (US$31.8 million) in the first quarter of 2025, compared with RMB142.8 million in the same period of 2024.

Grossmargin was 28.6% in the first quarter of 2025, compared with 25.9% in the same period of 2024. The increase was primarily due to a favorable change in the revenue mix and cost optimization initiatives.

Operatingexpenses were RMB153.5 million (US$21.2 million) in the first quarter of 2025, compared with RMB194.4 million in the same period of 2024. The decrease was primarily due to the fluctuation of share-based compensation expenses. The changes in share-based compensation expenses were primarily due to the changes in the fair value of the share incentive awards that the Company granted to its employees in line with the fluctuations in the Company's share price.

^1^ Non-GAAP net income and non-GAAP income from operations are non-GAAP financial measures.

Sellingexpenses were RMB59.0 million (US$8.1 million) in the first quarter of 2025, compared with RMB52.9 million in the same period of 2024, primarily due to an increase in branding expenses, slightly offset by a decrease in salaries, welfare benefits and share-based compensation expenses.

Non-GAAP Financial Measures

The Company uses non-GAAP net income, non-GAAP operating profit 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. Non-GAAP income from operations represents net operating profit excluding share-based compensation expenses. 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.
