Viomi Technology Co., Ltd (the “Company”) is a holding company incorporated under the Laws of the Cayman Islands in January 2015. The Company, through its consolidated subsidiaries and “VIEs” (collectively referred to as the “Group”) is primarily engaged in the operation of developing and selling Home water solution businesses products in the People’s Republic of China (the “PRC”).

As of June 30, 2026, details of the Company’s principal subsidiaries and VIEs were as follows:

 SCHEDULE OF PRINCIPAL SUBSIDIARIES AND VIES

The Company, through Lequan or Zhumeng Hulian, entered into a series of contractual arrangements, including: (1) exclusive consultation and service agreements; (2) exclusive purchase option agreements, (3) shareholder voting proxy agreements and (4) equity pledge agreements with Beijing Viomi, Guangdong Interconnect and their shareholders, respectively. These arrangements enable Lequan or Zhumeng Hulian through their PRC subsidiaries to (1) have power to direct the activities that most significantly affects the economic performance of the VIEs, through the exercise of the shareholders’ rights under the shareholder voting proxy agreement as the shareholders’ meetings of the VIEs appoint the board of directors of the VIEs, and (2) receive the economic benefits of the VIEs that could be significant to the VIEs through the exclusive consultation and service agreement. Accordingly, Lequan or Zhumeng Hulian are considered the primary beneficiaries of the respective VIEs and have consolidated the VIEs’ financial results of operations, assets and liabilities in the Company’s consolidated financial statements.

In making the conclusion that Lequan or Zhumeng Hulian are the primary beneficiaries of the VIEs, the Company believes Lequan or Zhumeng Hulian’s rights under the terms of the option agreement provide them with a substantive kick-out right. As advised by the Company’s PRC legal counsel, the Company believes the terms of the option agreement are valid, binding and enforceable under PRC laws and regulations currently in effect. The Company also believes that the consideration which is the minimum amount permitted by the applicable PRC law to exercise the option does not represent a financial barrier or disincentive for Lequan or Zhumeng Hulian to currently exercise their rights under the exclusive option agreement.

A simple majority vote of Lequan or Zhumeng Hulian’s board of directors is required to pass a resolution to exercise their rights under the option agreement. Lequan or Zhumeng Hulian’s rights under the option agreement give them the power to control the shareholders of Beijing Viomi and Guangdong Interconnect In addition, Lequan or Zhumeng Hulian’s rights under the shareholder voting proxy agreement also reinforce their abilities to direct the activities that most significantly impact the VIEs’ economic performance. The Company also believes that this ability to exercise control ensures that the VIEs will continue to execute consultation and service agreements and also ensures that consultation and service agreements will be executed and renewed indefinitely unless a written agreement is signed by all parties to terminate it or a mandatory termination is requested by PRC laws or regulations. Lequan and Zhumeng Hulian have the rights to receive substantially all of the economic benefits from the VIEs.

On March 20, 2026, the exclusive consultation and service agreements and equity pledge agreements between Lequan, Beijing Viomi and each of the shareholders of Beijing Viomi was subsequently amended and restated, and the terms were substantially similar to the exclusive consultation and service agreements described before. Other than the amendments described above, there have been no material changes to the contractual arrangements with the VIEs, the Company’s determination of the primary beneficiary of the VIEs, or the related risks since December 31, 2025.

The Company believes that the contractual arrangements among its subsidiaries, their VIEs and their respective shareholders are in compliance with PRC laws and regulations and are legally enforceable. However, uncertainties in the PRC legal system could limit Lequan and Zhumeng Hulian’s ability to enforce the contractual arrangements. If the legal structure and contractual arrangements were found to be in violation of PRC laws and regulations, the PRC government could could take various regulatory or enforcement actions that could adversely affect the Company’s business and its ability to consolidate the VIEs.
