(1)	Each American depositary share ("ADS") represents three (3) Class A ordinary shares, with a par value of US$0.00001 per share, of Viomi Technology Co., Ltd (the "Company").
(2)	On October 8, 2026, Viomi Limited converted an aggregate of 9,000,000 Class A ordinary shares into 3,000,000 ADSs, each representing three Class A ordinary shares of the Company. These 9,000,000 Class A ordinary shares consisted of (i) 6,800,000 Class A ordinary shares converted on a one-for-one basis on September 30, 2026 from an equal number of Class B ordinary shares previously held by Viomi Limited, and (ii) 2,200,000 Class A ordinary shares previously held by Viomi Limited. The foregoing transaction constituted solely a change in the form of securities held by Viomi Limited and did not result in any substantial change in the Reporting Person's aggregate beneficial ownership in the securities of the Company.
(3)	Viomi Limited is wholly owned by a trust established for the benefit of the Reporting Person and his family.
(4)	VioCloud Limited is wholly owned by Foshan Yunmi Electric Appliances Technology Co., Ltd.
