RIGOL Technologies Co., Ltd. has formalised the establishment of an Environmental, Social and Governance (ESG) Committee under its Board of Directors, defining its structure, responsibilities and operating procedures.

Key structural details • Composition: The ESG Committee will consist of five directors, including one chairperson elected from among the members. • Nomination and tenure: Members are nominated by the Board chair, a majority of independent directors, or at least one-third of all directors, and serve concurrent terms with the Board, with eligibility for re-election. • Quorum and voting: Meetings require attendance by more than two-thirds of members, and resolutions pass with approval from over half of the committee.

Primary mandates 1. Assess and recommend policies on sustainable development and other ESG matters. 2. Review ESG reports and significant ESG issues before submitting recommendations to the Board. 3. Undertake additional tasks authorised by the Board or mandated by applicable regulations.

Operating guidelines • Frequency: At least one meeting per year, with extraordinary sessions allowed as required. • Notice period: Minimum three days’ advance notice, except in emergencies. • Meeting formats: In-person, telephone, video conference or written circulation are all permitted. • Confidentiality: All participants must maintain confidentiality regarding deliberations and decisions.

Implementation and oversight The committee reports directly to the Board, which retains ultimate decision-making authority. Meeting minutes will be archived by the Board secretary, and the terms become effective upon Board approval. Any future regulatory changes will supersede conflicting provisions in the terms.

By codifying these procedures, RIGOL aims to enhance its ESG management system, strengthen sustainable development capabilities and align corporate governance practices with national regulations and its Articles of Association.
