On March 22, 2024, Duke Energy Corporation filed a definitive proxy statement soliciting proxies and urged the shareholders to vote against the proposal requesting board that seek an audited report assessing how applying the findings of the Energy Policy Research Foundation and similar studies would affect the assumptions, costs, estimates, and valuations underlying its financial statements, including those related to long-term commodity and carbon prices, remaining asset lives, future asset retirement obligations, capital expenditures and impairments. The Board should obtain and ensure publication of the report by February 2025, at reasonable cost and omitting proprietary information, submitted by National Center for Public Policy Research at the 2024 Annual Meeting to be held on May 9, 2024.
