Viomi Technology shares surge 10.56% premarket on 76.6% revenue growth and 64.7% net income increase from core home water systems.

Viomi Technology surged 10.56% in premarket trading following the release of its strong first-half 2025 unaudited financial results and a $20 million stock buyback plan. Net revenues rose 76.6% year-over-year to RMB1.48 billion, driven by an 84.8% increase in home water systems revenue, while net income jumped 64.7% to RMB120.4 million. The CEO highlighted strategic reorganization, product innovation (e.g., MASTER M1, Kunlun 4 Pro), and global expansion as key growth drivers. The announced buyback further signaled confidence in the company’s high-quality, sustainable growth trajectory, aligning with the stock’s upward momentum. Marginal pressures from higher operating expenses and lower gross margins were offset by robust top-line performance and profitability expansion.
