RLX Technology Announces Unaudited First Quarter 2023 Financial Results

BEIJING, May 17, 2023 /PRNEWSWIRE/ - RLX Technology Inc. ("RLX Technology" or the "Company") (NYSE: RLX), a leading branded e-vapor company in China, today announced its unaudited financial results for the first quarter ended March 31, 2023.

First Quarter 2023 Financial Highlights

"In the first quarter of 2023, our focus remained on optimizing our product offerings under the new regulatory framework," said Ms. Ying (Kate) Wang, Co-founder, Chairperson of the Board of Directors, and CEO of RLX Technology. "While we strive to develop diversified, new, approved products that cater to users' various demands, the prevalence of illegal products has posed near-term challenges to our sales and disrupted the recovery pace of the industry as a whole. The increasing efforts put forth by the regulators to crack down on illegal products have been encouraging, and we are hopeful that these will be effective in supporting the creation of fair and orderly market conditions, prompting a return to sustainable growth for law-abiding companies such as RLX Technology. If illegal products can be pushed out of the market, we believe adult users will gradually adapt to products that meet national standards. As a trusted e-vapor brand for adult smokers, we remain committed to providing compliant, superior products that meet our users' needs as we continue exploring growth opportunities in the evolving industry."

"We experienced an incredibly challenging first quarter as illegal-flavored products caused users' slow shift to products that meet the national standards and drove our total revenues down to RMB188.9 million. Our gross margin declined as we incurred the full effect of the new excise tax in the first quarter," said Mr. Chao Lu, Chief Financial Officer of RLX Technology. "We are pleased that market conditions have improved, following the regulators' strict actions to combat illegal products since March 2023. As a result, our sales are showing signs of recovery. Looking ahead, we will continue improving our operational efficiency and believe our profitability will gradually recover. Our resilient business model and solid cash position will support us as we navigate the market dynamics, enabling us to deliver sustainable value to our stakeholders as the industry regains momentum."

First Quarter 2023 Financial Results

Net revenues were RMB188.9 million (US$27.5 million) in the first quarter of 2023, compared with RMB1,714.5 million in the same period of 2022. The decrease was primarily due to the discontinuation of our older products and the negative impact of illegal-flavored products in the market, which led to users' slower-than-expected adoption of our new products that comply with national standards.

Gross profit was RMB45.7 million (US$6.7 million) in the first quarter of 2023, compared with RMB657.0 million in the same period of 2022.

1 Non-GAAP net income is a non-GAAP financial measure. For more information on the Company's non-GAAP financial measures, please see the section “Non-GAAP Financial Measures” and the table captioned "Unaudited Reconciliation of GAAP and Non-GAAP Results" set forth at the end of this press release.

Gross margin was 24.2% in the first quarter of 2023, compared with 38.3% in the same period of 2022. The decrease was primarily due to the imposition of a 36% excise tax which came into effect on November 1, 2022.

Operating expenses were RMB418.9 million (US$61.0 million) in the first quarter of 2023, compared with RMB33.6 million in the same period of 2022. The increase was primarily due to the change of RMB240.0 million (US$34.9 million) in share-based compensation expenses in the first quarter of 2023, compared with positive RMB325.2 million in the same period of 2022. The change in share-based compensation expenses consisted of (i) RMB24.0 million (US$3.5 million) recognized in selling expenses, (ii) RMB201.3 million (US$29.3 million) recognized in general and administrative expenses, and (iii) RMB14.7 million (US$2.1 million) recognized in research and development expenses. The change in share-based compensation expenses was primarily due to the changes in the fair value of the share incentive awards that the Company granted to its employees affected by the fluctuations of the Company's share price.

Selling expenses were RMB85.8 million (US$12.5 million) in the first quarter of 2023, compared with RMB75.9 million in the same period of 2022, mainly driven by the fluctuation of share-based compensation expenses.

General and administrative expenses were RMB256.5 million (US$37.4 million) in the first quarter of 2023, compared with positive RMB66.4 million in the same period of 2022, mainly driven by the fluctuation of share-based compensation expenses.

Research and development expenses were RMB76.7 million (US$11.2 million) in the first quarter of 2023, compared with RMB24.0 million in the same period of 2022, mainly driven by the fluctuation of share-based compensation expenses.

Loss from operations was RMB373.2 million (US$54.3 million) in the first quarter of 2023, compared with an income from operations of RMB623.4 million in the same period of 2022.

Income tax benefit was RMB17.6 million (US$2.6 million) in the first quarter of 2023, compared with income tax expense of RMB112.6 million in the same period of 2022.

U.S. GAAP net loss was RMB56.3 million (US$8.2 million) in the first quarter of 2023, compared with U.S. GAAP net income of RMB687.1 million in the same period of 2022.

Non-GAAP net income was RMB183.6 million (US$26.7 million) in the first quarter of 2023, compared with RMB361.8 million in the same period of 2022.

U.S. GAAP basic and diluted net loss per American depositary share ("ADS") were RMB0.043 (US$0.006), in the first quarter of 2023, compared with U.S. GAAP basic and diluted net income per ADS of RMB0.528 and RMB0.521, respectively, in the same period of 2022.

Non-GAAP basic and diluted net income per ADS2 were RMB0.139 (US$0.020) and RMB0.136 (US$0.020), respectively, in the first quarter of 2023, compared with non-GAAP basic and diluted net income per ADS of RMB0.284 and RMB0.281, respectively, in the same period of 2022.

Non-GAAP Financial Measures

The Company uses non-GAAP net income 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 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.
