RLX Technology Announces Unaudited Second Quarter 2026 Financial Results

SHENZHEN, August 14, 2026 /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 second quarter ended June 30, 2026.

Second Quarter 2026 Financial Highlights

"We delivered solid second quarter results as we continued to strengthen our global business with a focus on quality, stability, and long-term resilience," said Ms. Ying (Kate) Wang, Co-founder, Chairperson, and Chief Executive Officer of RLX Technology. "As our industry matures, competitive advantage is increasingly defined not only by product innovation but also by retail execution and shelf-space leadership. We have refined our global route-to-market strategies accordingly – deepening store-level execution in Asia while advancing a dual-engine approach in Europe that balances strategic investment in top-tier local partners with organic growth. At the same time, we are expanding beyond our leadership in e-vapor into a broader portfolio of smoke-free products, scaling our newly launched modern oral nicotine pouches and building our presence across other smokeless categories. Supported by a rock-solid balance sheet and disciplined capital management, we are confident that pairing greater channel autonomy with user-centric products and multi-category innovation will continue to drive sustainable growth."

Mr. Chao Lu, Chief Financial Officer of RLX Technology, commented, "Second quarter net revenues were RMB1.01 billion, up 14.8% year over year, with gross profit rising 47.8% year over year to RMB357.8 million. As expected, revenues and gross profit moderated from the first quarter, which included a disclosed one-time benefit due to the change of export related regulation. In July 2026, we acquired a 51% equity interest in one of Western Europe's largest distributors of next-generation smoke-free and FMCG products, deepening our presence in the region. The entity brings an extensive offline distribution footprint and a proprietary B2B digital marketplace serving a broad base of retail merchants, supporting long-term regional development. Moving forward, we remain dedicated to disciplined capital allocation, balancing strategic growth investments with ongoing shareholder returns to maximize long-term shareholder value."

Second Quarter 2026 Financial Results

Net revenues were RMB1,010.5 million (US$148.9 million) in the second quarter of 2026, increasing by 14.8% from RMB880.0 million in the same period of 2025. The increase was primarily due to the Company’s international expansion and contributions from the Company’s May 2025 acquisition. Net revenues from international business represented 68.5% of net revenues for the period.

Gross profit was RMB357.8 million (US$52.7 million) in the second quarter of 2026, increasing by 47.8% from RMB242.1 million in the same period of 2025.

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

Gross margin increased to 35.4% in the second quarter of 2026 from 27.5% in the same period of 2025, primarily due to a favorable change in the revenue mix and further supply chain optimization.

Operating expenses were RMB227.5 million (US$33.5 million) in the second quarter of 2026, compared with RMB203.1 million in the same period of 2025. The increase was driven by higher salary and welfare expenses primarily related to the Company’s May 2025 acquisition, partially offset by a significant decrease in share-based compensation expenses.

Selling expenses were RMB123.7 million (US$18.2 million) in the second quarter of 2026, compared with RMB84.6 million in the same period of 2025, primarily due to an increase in salary and welfare expenses, branding expenses, depreciation and amortization expenses related to the Company’s May 2025 acquisition, partially offset by a decrease in share-based compensation expenses.

General and administrative expenses were RMB74.4 million (US$11.0 million) in the second quarter of 2026, compared with RMB88.4 million in the same period of 2025, primarily due to a significant decrease in share-based compensation expenses, partially offset by an increase in legal and other consulting fees.

Research and development expenses were RMB29.4 million (US$4.3 million) in the second quarter of 2026, compared with RMB30.1 million in the same period of 2025. The slight decrease was primarily due to a decrease in share-based compensation expenses.

U.S. GAAP income from operations was RMB130.4 million (US$19.2 million) in the second quarter of 2026, increasing by 234.7% from RMB39.0 million in the same period of 2025.

Non-GAAP net income was RMB238.8 million (US$35.2 million) in the second quarter of 2026, compared with RMB291.2 million in the same period of 2025.

Non-GAAP basic and diluted net income per ADS² were RMB0.190 (US$0.028) and RMB0.178 (US$0.026), respectively, in the second quarter of 2026, compared with non-GAAP basic and diluted net income per ADS of RMB0.234 and RMB0.218, respectively, in the same period of 2025.

Strategic Investment

With its multi-channel logistics network and a proprietary B2B digital ordering platform, the entity provides an established and highly efficient route-to-market across key European territories. Through this strategic investment, RLX Technology intends to leverage its global supply chain capabilities and capital resources to drive deep commercial collaboration with this entity, aiming to optimize costs and capture cross-selling synergies.

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.
