GUANGZHOU, China, March 25, 2025 – Viomi Technology Co., Ltd (“Viomi” or the “Company”) (NASDAQ: VIOT), a leading technology company for home water solutions in China, today announced its unaudited financial results for the second half and full year ended December 31, 2024.

Second Half 2024 Financial Highlights1

Full Year 2024 Financial Highlights

Mr. Xiaoping Chen, Founder and CEO of Viomi, commented: “The successful completion of our business reorganization in August marked a pivotal milestone for Viomi, enabling us to sharpen our focus on our core home water solutions. This strategic shift has driven our strong performance in 2024, with full-year net revenues reaching RMB2.1 billion and income from operations totaling RMB156.3 million, both exceeding our previous guidance. Revenues from home water systems grew by 39.0% year over year, significantly fueling our overall business expansion. Additionally, we enhanced our operational efficiency, achieving a net income of RMB62.3 million, reversing the losses reported in 2022 and 2023. As we move forward, Viomi is back on a fast track to high-quality growth and is well-positioned to seize new opportunities in the market.”

“With growing public awareness of the importance of healthy drinking water and supportive policies fostering product innovations, the home water purification market presents huge opportunities. Leveraging over a decade of deep expertise in the water purification industry, Viomi remains committed to continuous product innovation and aims to redefine home water purification through AI technology. Our comprehensive product portfolio ranges from Point-of-Use RO series, such as under-the-sink and installation-free products, to whole-house softening and purification solutions. Advanced features such as natural mineral water infusion, instant heating and cooling, and ice making, empower users with real-time water quality monitoring, proactive filter replacement reminders, and seamless one-click reordering through our app. Furthermore, our intelligent self-cleaning water circuit technology, supported by AI diagnostics, greatly extends filter lifespan and reduces usage costs, enhancing both efficiency and sustainability. By addressing a wide range of household water usage scenarios and catering to diverse drinking water needs across the global market, Viomi provides a smarter, more reliable, and efficient water purification experience for consumers worldwide.”

1 In August 2024, Viomi completed a strategic reorganization, divesting the Company’s IoT@Home portfolio products, excluding range hoods, gas stoves, and water heaters (the “Divested Business”). As a result, the Divested Business has been deconsolidated from the Company and its historical financial results are reported as discontinued operations in the Company’s consolidated financial statements. The financial information and non-GAAP financial information disclosed in this press release are presented based on continuing operations, unless specifically stated otherwise.

2 Starting from the second half of 2024, the Company has reclassified its revenue streams into three categories to better reflect the Company’s strategies and business focus: (i) home water systems, which include revenues from smart water purification products, water heaters, water kettles, water quality meters, and other related businesses; (ii) consumables, which include revenues from various water filters designed for the smart water purifiers; and (iii) kitchen appliances and others, which include revenues from range hoods, gas stoves, and other small appliances, as well as installation services for Viomi’s products.

“Our August 2024 business reorganization swiftly streamlined our organization, comprehensively improved our operational efficiency, and sharpened our focus on home water solutions, leveraging our core strengths to drive sustainable growth. We established the Integrated Product Marketing System (IPMS), which unifies our product, channel, and brand strategies under a cohesive marketing framework. By prioritizing consumer experience and aligning resources with market demand, we have strengthened Viomi’s brand awareness and expanded our market share in the water purification industry.”

“In the domestic market, Viomi leads the healthy mineral water trend. The first half of 2024 saw the launch of the Viomi Kunlun Mineral AI Water Purifier, integrating advanced AI technology to optimize the purification process. Featuring an innovative AI-powered mineralizing filter technology, it ensures the sustained release of beneficial minerals. This produces purified water with a mineral composition closely resembling natural mineral water, providing our users with fresh, mineral-rich water at home. During the 2024 Double 11 Shopping Festival, our AI water purifier ranked fourth, fifth, and ninth on the brand leaderboards of the Douyin, Pinduoduo, and Tmall platforms, respectively, further reinforcing our brand influence.”

“In North America, we introduced the Vortex series of under-the-sink RO water purifiers, designed for users who value convenience and efficiency. Its self-installation feature has been well-received, with over 80% of users reporting a smooth installation process averaging only 20 minutes. The Vortex’s tankless design and DIY filter replacement can greatly save space and time for users. A three-to-one wastewater ratio and four-year long-lasting filter lifespan enhance filtration efficiency, reduce water waste, and lower maintenance costs, delivering a superior user experience. This product made a strong international debut on the Kickstarter crowdfunding platform on November 5, 2024, surpassing its funding goal on the first day with 168 backers contributing over 1,200% of the target. Following this success, the Vortex series officially commenced sales on Amazon in the U.S. on December 16, 2024, receiving high recognition and positive feedback with strong customer demand. To further solidify our presence in the global market, Viomi participated for the first time in CES 2025 in Las Vegas in January 2025. Our intelligent home water solutions garnered widespread recognition from industry experts and attendees, reinforcing Viomi’s reputation as a smart home water solutions innovator.”

“Viomi’s ‘Water Purifier Gigafactory’ is fundamental to our manufacturing and technology development capabilities, featuring a highly integrated industrial chain and highly automated production lines. With 100% in-house manufacturing and a fully traceable quality control system for core components, we maximize economies of scale. To strengthen innovation, we have established two major laboratory systems focused on advanced technology research and product compliance and reliability. These laboratories meet the stringent testing standards of various global markets, allowing us to rapidly adapt to evolving and diversified market demands while maintaining consistent and reliable product performance. As of today, Viomi has filed nearly 1,800 global patent applications, significantly outpacing the industry average. Looking forward, powered by the dual engines of advanced manufacturing and continuous innovation, we are well-positioned to further elevate our competitive edge in the water purification industry.”

“Viomi is embarking on a new chapter as we move into 2025, guided by our vision of ‘Global Water’ and our commitment to providing fresh, healthy water to users worldwide. To achieve this, we will focus on four key strategic initiatives: First, we will strengthen our domestic market presence through ‘trade-in’ policy incentives and advancements in AI technology to accelerate product innovation, meeting consumers’ growing demand for an enhanced lifestyle. Second, we will drive international market expansion, further penetrating key markets such as North America and Southeast Asia. Through region-specific product development and enhanced brand positioning, we aim to elevate Viomi’s international market visibility. Third, we will continue to fortify our water purification product portfolio, maintaining an unwavering commitment to research and development. By leading industry innovation, we strive to provide smarter, healthier water purification solutions for customers worldwide. Fourth, we will continue to deepen collaborations with our strategic partners, maximizing the advantages of the ‘Water Purification Gigafactory’ to scale our advantages. This will enable us to achieve synergy in growth and profitability, ultimately creating long-term value for both our customers and shareholders,” Mr. Chen concluded.

Use of Non-GAAP Measures

The Company uses non-GAAP operating income/(loss), non-GAAP net income/(loss), and non-GAAP net income income/(loss) attributable to ordinary shareholders of the Company, in evaluating its operating results and for financial and operational decision-making purposes. Non-GAAP operating income/(loss) is income/(loss) from operations excluding share-based compensation expenses. Non-GAAP net income/(loss) is net income/(loss) excluding share-based compensation expenses. Non-GAAP net income/(loss) attributable to ordinary shareholders of the Company is net income/(loss) attributable to ordinary shareholders excluding share-based compensation expenses. The non-GAAP adjustments do not have any tax impact as share-based compensation expenses are non-deductible for income tax purposes.

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.
