# V. OVERSIGHT

The three standing management committees (Executive Committee, Commitments Committee, and Risk Committee) provide daily oversight of the Company's environmental principles. The Board of Directors, through the Vistra Sustainability and Risk Committee, oversees the Company's core vision and values as it pertains to the Company's approach to sustainability policies and reporting, including environmental principles.

Directly reporting to the CEO is Stacey Doré, Chief Strategy & Sustainability Officer and Executive Vice President of Public Affairs (CSO). The CSO manages the Corporate Sustainability team, responsible for Vistra's ESG reporting and disclosures, and presents to the Sustainability and Risk Committee of the board at least quarterly, at each regularly scheduled committee meeting. Within the Vistra management team, the CSO is a member of Vistra's Executive Committee, which consists of the CEO and his direct reports. The Executive Committee meeting forum includes discussion and decision-making related to general strategy, policy items, and operational updates. [...] Sustainability and climate-related issues are discussed at each scheduled quarterly Sustainability and Risk Committee meeting and on a more frequent basis as necessary. In addition, at least annually, the board will review and discuss with management the Company's assessment of greenhouse gas-related risks, including physical, transition, regulatory, reputational, and/or market risks related to climate change, and management's process for the identification, evaluation, and mitigation of transition risks related to climate change.

Describe the process(es) your organization has in place to ensure that your engagement activities are consistent with your overall climate change strategy[…]Annually, Vistra reviews all its memberships with trade groups, associations, and other third-party organizations to discern whether their positions are materially inconsistent with Vistra's views. If Vistra determines that a group is taking a materially inconsistent position from the Company's views, the Company will advocate within the organization to seek to align our positions and if that is unsuccessful may withdraw from or otherwise disassociate from that organization.
