Cautionary Note Regarding Forward-Looking Statements

The presentation referenced above contains forward-looking statements based on current expectations and plans that involve risks and uncertainties. All statements, other than statements of historical fact, that address activities, events or developments that we expect or anticipate to occur in the future, including matters such as: the timing and amount of future capital expenditures, business strategy, regulatory actions, member demand, greenhouse gas emissions, financial projections, sources of capital and the development, construction or operation of facilities, including our future generation resources, are forward-looking statements. Although we believe that in making these forward-looking statements our expectations are based on reasonable assumptions, we caution the reader not to put undue reliance on these forward-looking statements, which are not guarantees of future performance. Forward-looking statements involve uncertainties and there are important factors, many of which are outside our control, which could cause actual results to differ materially from those expressed or implied by these forward-looking statements. Some of the risks, uncertainties and assumptions that may cause actual results to differ from these forward-looking statements are described under the headings “Cautionary Statement Regarding Forward-Looking Information” in our quarterly report on Form 10-Q for the quarterly period ended September 30, 2025 and “Item 1A—Risk Factors” in our annual report on Form 10-K for the fiscal year ended December 31, 2024. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in the presentation may not occur. Any forward-looking statement speaks only as of the date of the presentation and, except as required by law, we undertake no obligation to update any information contained in the presentation.
