GUANGZHOU, China, March 27, 2023 – Viomi Technology Co., Ltd (“Viomi” or the “Company”) (NASDAQ: VIOT), a leading IoT @ Home technology company in China, today announced its unaudited financial results for the fourth quarter and full year ended December 31, 2022.

Fourth Quarter 2022 Financial and Operating Highlights

Full Year 2022 Financial and Operating Highlights

Mr. Xiaoping Chen, Founder and CEO of Viomi, commented, “Due to the adverse impact of the COVID-19 pandemic and macro headwinds, we experienced a year-over-year decline in revenues in the fourth quarter of 2022 and our business scale was greatly affected by external factors and strategic adjustments throughout 2022. Nevertheless, our gross margin increased by 3.2% quarter-over-quarter in the fourth quarter of 2022, benefiting from our product portfolio optimization efforts. Our full-year gross margin in 2022 also kept stable as compared with 2021 despite fluctuations throughout the year. To adapt to the uncertainties in the macro environment of 2022, we implemented optimization measures across our business as we strove to improve our operating results and positioned ourselves to thrive in the post-pandemic era.

“First, to strengthen our product portfolio, we leveraged our competitive advantages and continued to enhance our core product categories with upgraded functionalities. Equipped with industry-leading technology, our AI water purification products, Viomi’s longest-standing category, achieved a 6% year-over-year sales growth in the fourth quarter despite various challenges. Going forward, we will strengthen our efforts to optimize distribution channels, hone our existing technological advantages, and further deepen the market penetration of our products. We will also expand our footprint overseas with products such as air conditioners, washing machines and refrigerators to accelerate the recovery of our business scale.

“Furthermore, to improve our operational efficiency, we implemented more disciplined cost control measures during 2022. As a result, both selling and marketing expenses and research and development expenses decreased in the fourth quarter of 2022 compared with the prior year period. In particular, selling and marketing expenses as the proportion of net revenues narrowed compared with that in the second quarter of 2022 on a similar revenue scale. We will continue to optimize costs, streamline organizational structure and improve operational efficiency to boost profitability,” Mr. Chen commented.

“While refining our business operations, we remained firmly committed to bringing more useful and user-friendly, whole-house intelligent solutions to consumers and continuously improving the intelligent experience of our products. In October 2022, we hosted the virtual 2022 Fall Software Launching Event, ‘AI: Helpful 2.0’. This online event focused on software upgrades and product iteration across four dimensions, including healthcare, energy conservation and environmental protection, proactive intelligence, and natural interaction, further improving our one-stop IoT home solutions from the software side. In November 2022, Viomi’s one-stop IoT home solution platform, HomeMap app, was awarded the Precision Science and Technology Award by the Ministry of Science and Technology of China and the National Office for Science and Technology Awards of China. Furthermore, during the year, we received approvals to establish both our Doctoral Workstation of Guangdong Province and our Foshan Enterprise Postdoctoral Workstation, which will facilitate talent cultivation and project incubation of Viomi. As a leading technology brand, Viomi will continue to devote resources to research and development and focus on technological innovation, driving progress industry-wide.”

Mr. Chen concluded, “The market potential for whole-house intelligence is tremendous. and Viomi has already completed the layout of the ‘one-stop IoT home’ solution. As we progress through 2023, we will maintain sufficient financial reserves and strictly control costs to provide strong support for our brand development and product upgrades. Meanwhile, we will steadily expand our business domestically and introduce new product categories in overseas markets as we seek to accelerate the recovery of our profitability and achieve healthy and sustainable growth.”

Fourth Quarter 2022 Financial Results

REVENUE

Net revenues were RMB910.5 million (US$132.0 million), compared to RMB1,332.8 million for the fourth quarter of 2021. The decline was mainly due to a decrease in revenues from IoT@Home portfolio and small appliances and others.

GROSS PROFIT

Gross profit was RMB209.7 million (US$30.4 million), compared to RMB341.5 million for the fourth quarter of 2021. Gross margin was 23.0%, compared to 25.6% for the fourth quarter of 2021.

OPERATING EXPENSES

Total operating expenses decreased by 19.4% to RMB274.7 million (US$39.8 million) from RMB340.7 million for the fourth quarter of 2021, primarily due to a decrease in selling and marketing expenses, partially offset by an increase in general and administrative expenses.

Research and development expenses decreased by 23.6% to RMB74.7 million (US$10.8 million) from RMB97.8 million for the fourth quarter of 2021, mainly due to a decrease in research and development experts and related salaries, as well as the Company’s continued efforts in R&D efficiency improvement.

Selling and marketing expenses decreased by 29.7% to RMB151.1 million (US$21.9 million) from RMB214.8 million for the fourth quarter of 2021, mainly due to a decrease in logistics and marketing expenses.

Use of Non-GAAP Measures

The Company uses non-GAAP operating income, non-GAAP net income, non-GAAP net income attributable to ordinary shareholders of the Company, non-GAAP basic and diluted net income per ordinary share and non-GAAP basic and diluted net income per American depositary share ("ADS"), which are non-GAAP financial measures, in evaluating its operating results and for financial and operational decision-making purposes. Non-GAAP operating income is income from operations excluding share-based compensation expenses. Non-GAAP net income is net income excluding share-based compensation expenses. Non-GAAP net income attributable to ordinary shareholders of the Company is net income attributable to ordinary shareholders excluding share-based compensation expenses. Non-GAAP basic and diluted net income per ordinary share is non-GAAP net income attributable to ordinary shareholders divided by weighted average number of ordinary shares used in the calculation of non-GAAP basic and diluted net income per ordinary share. Non-GAAP basic and diluted net income per ADS is non-GAAP net income attributable to ordinary shareholders divided by weighted average number of ADS used in the calculation of non-GAAP basic and diluted net income per ADS. The non-GAAP adjustments do not have any tax impact as share-based compensation expenses are non-deductible for income tax purpose.

The Company believes that non-GAAP financial measures help identify underlying trends in its business by excluding the impact of share-based compensation expenses, which are non-cash charges, and these measures provide useful information about the Company's operating results, enhance the overall understanding of the Company's past performance and future prospects and allow for greater visibility with respect to key metrics used by the Company's management in its financial and operational decision-making.

Non-GAAP financial measures should not be considered in isolation or construed as alternative to income from operations, net income, or any other measure of performance or as an indicator of the Company's operating performance. Investors are encouraged to review the historical non-GAAP financial measures to the most directly comparable GAAP measures. Non-GAAP financial measures presented 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 the Company's data. We encourage investors and others to review its financial information in its entirety and not rely on a single financial measure. Reconciliations of the Company's non-GAAP financial measures to the most directly comparable GAAP measures are included at the end of this press release.
