Viomi Technology Co., Ltd Reports First Half 2025 Unaudited Financial Results

GUANGZHOU, China, November 10, 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 six months ended June 30, 2025.

First Half 2025 Financial Highlights¹

• Net revenues reached RMB1,477.6 million (US$206.3 million), representing an increase of 76.6% from RMB836.6 million for the same period of 2024.

• Net income attributable to ordinary shareholders of the Company was RMB120.4 million (US$16.8 million), representing an increase of 64.7% from RMB73.1 million for the same period of 2024.

Mr. Xiaoping Chen, Founder and CEO of Viomi, commented: “In the first half of 2025, we sustained our strong growth momentum following our strategic reorganization, achieving another record-high performance in revenue. Our total net revenues reached RMB1.48 billion, representing a year-over-year increase of 76.6%. Our net income reached RMB120.5 million with a net margin of 8.2%. These results underscore the vision and effectiveness of our strategic focus on the home water solutions. We have entered a new stage of high-quality, sustainable growth where we simultaneously grow scale and expand profitability.”

“Amid rising global demand for healthy drinking water, we remain committed to our mission of ‘AI for Better water.’ We are growing our home water solutions business globally through three key engines: product innovation, market expansion, and brand enhancement. In the first half of the year, revenues from our core business ‘Home Water Systems’ increased by 84.8% year over year, serving as the primary driver of our scale expansion. Operational efficiency also improved significantly.”

“Regarding product innovation, we launched a series of industry-leading solutions tailored to meet the diverse needs of different markets globally. In North America, we successfully introduced the MASTER M1, our first smart under-sink water purifier equipped with a 9-stage RO filtration system and an AI-powered touchscreen faucet that provides real-time monitoring of water quality, volume, and filter status. Our Vortex series also delivered strong results, ranking sixth in the under-sink tankless water purifier category on Amazon and receiving positive reviews from users. In Malaysia, we launched the INNO Mineral Water Purifier in partnership with a leading local channel distributor. With its compact design and advanced mineral water technology, the product meets Southeast Asian households’ demand for both efficient space utilization and healthy drinking water. In China, we launched the Kunlun 4 Pro AI alkaline mineral water purifier, combining mineralization filters and AI-based regulation technology to simulate the composition of natural mineral water and enable dynamic pH control, allowing users to enjoy fresh, mildly alkaline mineral water at home.”

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.

“On the brand development front, we continued to strengthen Viomi’s brand image of ‘Technology + Health.’ We are delighted to have the renowned Chinese actress Ms. Shengyi Huang join us as our brand spokesperson. Her healthy and graceful image aligns perfectly with our brand philosophy of ‘making water better.’ In addition, we joined hands with Olympic champion Mr. Liang Tian as our brand partner to advocate for a healthy water drinking lifestyle. In Malaysia, we invited famous singer Ms. Shila Amzah to serve as our local brand ambassador, leveraging her extensive local influence to accelerate our local market penetration and strengthen user awareness.”

“With respect to manufacturing and R&D, our Water Purifier Gigafactory continued to advance its platform-based modularization strategy. By leveraging scalable functional module designs and flexible production lines, we were able to iterate products rapidly and respond to evolving global demand with agility. We are keenly focused on the launch of our overseas boutique factories. By integrating diversified functional modules, including instant heating, instant cooling, and ice-making, we will be able to expand our product portfolio and cater to regional water drinking preferences across North America, Europe, Southeast Asia, and beyond. To further strengthen our innovation, we continued to enhance two core laboratory systems: ‘Cutting-edge Technologies’ and ‘Product Compliance & Reliability.’ These laboratory systems ensure that our R&D processes comply with global certification standards and enable the rapid adoption of cutting-edge technologies. To date, Viomi has filed nearly 1,850 patents worldwide, establishing systemic technological barriers in critical areas such as AI water quality algorithms, mineral control, and energy-efficient water purification, laying a solid foundation to provide our users globally with a smarter and healthier water drinking experience.”

“Looking ahead, we will continue to deepen our ‘Global Water’ strategy, aiming to drive breakthroughs in four key aspects. First, we will accelerate overseas channel expansion to continuously strengthen our global influence by focusing on key international markets. Second, we will further fortify the differentiated positioning of the Kunlun Series, continuing to emphasize its healthy product positioning as ‘mineral water’ to lead a quality upgrade in China’s water purification consumption. Third, we will continue to advance technological iteration and product innovation through our modular platform by integrating new technologies, expanding our product portfolio, and meeting the personalized, scenario-specific drinking water needs of users worldwide. Lastly, we will deepen our collaboration with key strategic partners such as Xiaomi, JD.com, and Senheng, fully leveraging the scale advantages of our Gigafactory to deliver smarter, healthier water solutions and generate long-term, sustainable value for our shareholders,” Mr. Chen concluded.

First Half 2025 Financial Results

REVENUES

Net revenues were RMB1,477.6 million (US$206.3 million), an increase of 76.6% from RMB836.6 million for the same period of 2024, primarily attributable to the growth in the home water systems.

- Home water systems. Revenues from home water systems were RMB1,058.3 million (US$147.8 million), an increase of 84.8% from RMB572.7 million for the same period of 2024, primarily due to increased demand for home water system products.

- Consumables. Revenues from consumables were RMB123.2 million (US$17.2 million), a decrease of 12.6% from RMB141.0 million for the same period of 2024, primarily due to technological iterations that have extended filter lifespans and reduced replacement frequency.

- Kitchen appliances and others. Revenues from kitchen appliances and others were RMB296.1 million (US$41.3 million), an increase of 140.9% from RMB122.9 million for the same period of 2024, primarily due to increased sales of kitchen appliances to Xiaomi.

GROSS PROFIT

Gross profit was RMB391.2 million (US$54.6 million), compared to RMB259.2 million for the same period of 2024. Gross margin was 26.5%, compared to 31.0% for the same period of 2024. The decrease was primarily due to a change in product mix, as revenue contribution from kitchen appliances and other lower-margin products increased while the contribution from higher-margin consumables declined.

OPERATING EXPENSES

Total operating expenses were RMB281.4 million (US$39.3 million), an increase of 38.4% from RMB203.3 million for the same period of 2024, due to increased marketing and promotion expenditures, in addition to employee compensation costs from business expansion.

Research and development expenses were RMB89.3 million (US$12.5 million), an increase of 18.8% from RMB75.2 million for the same period of 2024, mainly attributable to an increase in employee compensation costs.

Selling and marketing expenses were RMB129.0 million (US$18.0 million), an increase of 33.6% from RMB96.6 million for the same period of 2024, mainly due to higher spending on marketing and promotions, coupled with increased employee compensation expenses.

General and administrative expenses were RMB63.0 million (US$8.8 million), an increase of 100.1% from RMB31.5 million for the same period of 2024, primarily due to increased employee compensation costs and a higher allowance for credit losses resulting from a higher accounts receivable balance.

INCOME FROM OPERATIONS

Income from operations was RMB118.8 million (US$16.6 million), compared to RMB72.5 million for the same period of 2024.

Non-GAAP operating income² was RMB126.0 million (US$17.6 million), compared to RMB83.1 million for the same period of 2024.

² “Non-GAAP operating income” is defined as income from operations excluding share-based compensation expenses. See “Use of Non-GAAP Measures” and “Reconciliation of GAAP and Non-GAAP Results” included in this press release.

NET INCOME³

Net income attributable to ordinary shareholders of the Company was RMB120.4 million (US$16.8 million), an increase of 64.7% from RMB73.1 million for the same period of 2024, which was in line with the revenue expansion.

Non-GAAP net income attributable to ordinary shareholders⁴ of the Company was RMB127.6 million (US$17.8 million), an increase of 52.5% from RMB83.7 million for the same period of 2024.

Use of Non-GAAP Measures

The Company uses non-GAAP operating income/(loss), non-GAAP net income/(loss), and non-GAAP net 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.

³ The year-over-year data are all presented in the continuing operations basis, unless otherwise specified.

⁴ “Non-GAAP net income attributable to ordinary shareholders of the Company” is defined as net income attributable to ordinary shareholders of the Company excluding share-based compensation expenses. See “Use of Non-GAAP Measures” and “Reconciliation of GAAP and Non-GAAP Results” included in this press release.

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.
