Forward-Looking Statements

This current report contains forward-looking statements within the meaning of the Securities Act of 1933 and the Securities Exchange Act of 1934. These statements include, but are not limited to, statements regarding management's intents, beliefs, and current expectations and typically contain, but are not limited to, the terms "anticipate," "potential," "expect," "forecast," "target," "will," "would," "intend," "believe," "project," "estimate," "plan" and similar words. Such forward-looking statements include, without limitation, statements with respect to the proposed use of proceeds from the transactions contemplated by the Purchase Agreements. Forward-looking statements are not intended to be a guarantee of future results, but instead constitute AES Ohio's current expectations based on reasonable assumptions. Forecasted financial information is based on certain material assumptions. These assumptions include, but are not limited to, our expectations regarding the timing of events, accurate projections of market conditions and regulatory rates, future interest rates, commodity prices, continued operating performance and electricity volume at distribution companies, as well as achievements of planned productivity improvements and growth investments at expected rates of return.

Actual results could differ materially from those projected in our forward-looking statements due to risks, uncertainties, and other factors. Important factors that could affect actual results are discussed in AES Ohio's filings with the Securities and Exchange Commission (the "SEC"), including, but not limited to, the risks discussed under Item 1A: "Risk Factors" and Item 7: "Management's Discussion & Analysis" in AES Ohio's 2024 Annual Report on Form 10-K and in subsequent reports filed with the SEC. Readers are encouraged to read AES Ohio's filings to learn more about the risk factors associated with AES Ohio's businesses.
