This report made by the Registrants contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934. Many forward-looking statements appear in “Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations,” but there are others throughout this document which may be identified by words such as “expect,” “anticipate,” “intend,” “plan,” “believe,” “will,” “should,” “could,” “would,” “project,” “continue” and similar expressions, and include statements reflecting future results or guidance and statements of outlook. These matters are subject to risks and uncertainties that could cause actual results to differ materially from those projected. Forward-looking statements in this document are presented as of the date of this document. Except to the extent required by applicable law, management undertakes no obligation to update or revise any forward-looking statement. Among the factors that could cause actual results to differ materially from those in the forward-looking statements are:

•Changes in economic conditions, electric market demand and demographic patterns in AEP service territories.
•The economic impact of increased global conflicts and trade tensions, and the adoption or expansion of economic sanctions, tariffs or trade restrictions.
•Inflationary or deflationary interest rate trends.
•New legislation adopted in the states in which we operate that alters the regulatory framework or that prevents the timely recovery of costs and investments.
•Volatility and disruptions in financial markets precipitated by any cause, including fiscal and monetary policy, turmoil related to federal budget or debt ceiling matters or instability in the banking industry; particularly developments affecting the availability or cost of capital to finance new capital projects and refinance existing debt.
•The availability and cost of funds to finance working capital and capital needs, particularly (a) if expected sources of capital such as proceeds from the sale of assets, subsidiaries and tax credits and anticipated securitizations do not materialize or do not materialize at the level anticipated, and (b) during periods when the time lag between incurring costs and recovery is long and the costs are material.
•Shifting demand for electricity.
•The impact of extreme weather conditions, natural disasters and catastrophic events such as storms, drought conditions and wildfires that pose significant risks including potential litigation and the inability to recover significant damages and restoration costs incurred.
•Limitations or restrictions on the amounts and types of insurance available to cover losses that might arise in connection with natural disasters or operations.
•The cost of fuel and its transportation, the creditworthiness and performance of parties who supply and transport fuel and the cost of storing and disposing of used fuel, including coal ash and SNF.
•The availability of fuel and necessary generation capacity and the performance of generation plants.
•The ability to recover fuel and other energy costs through regulated or competitive electric rates.
•The ability to build or acquire generation (including from renewable sources), transmission lines and facilities (including the ability to obtain any necessary regulatory approvals and permits) to meet the demand for electricity at acceptable prices and terms, including favorable tax treatment, cost caps imposed by regulators and other operational commitments to regulatory commissions and customers for generation projects, and to recover all related costs.
•The disruption of AEP’s business operations due to impacts on economic or market conditions, costs of compliance with potential government regulations, electricity usage, supply chain issues, customers, service providers, vendors and suppliers caused by pandemics, natural disasters or other events.
•New legislation, litigation or government regulation, including changes to tax laws and regulations, oversight of nuclear generation, energy commodity trading and new or modified requirements related to emissions of sulfur, nitrogen, mercury, carbon, soot or PM and other substances that could impact the continued operation, cost recovery and/or profitability of generation plants and related assets.
•The impact of federal tax legislation, including potential changes to existing tax incentives, on results of operations, financial condition, cash flows or credit ratings.
•The risks before, during and after generation of electricity associated with the fuels used or the by-products and wastes of such fuels, including coal ash and SNF.
•Timing and resolution of pending and future rate cases, negotiations and other regulatory decisions, including rate or other recovery of new investments in generation, distribution and transmission service and environmental compliance.
•Resolution of litigation or regulatory proceedings or investigations.
•The ability to efficiently manage and recover operation, maintenance and development project costs.
•Prices and demand for power generated and sold at wholesale.
•Changes in technology, particularly with respect to energy storage and new, developing, alternative or distributed sources of generation.

vi

•The ability to recover through rates any remaining unrecovered investment in generation units that may be retired before the end of their previously projected useful lives.
•Volatility and changes in markets for coal and other energy-related commodities, particularly changes in the price of natural gas.
•The impact of changing expectations and demands of customers, regulators, investors and stakeholders, including development, adoption, and use of artificial intelligence by us, our customers and our third party vendors and evolving expectations related to environmental, social and governance concerns.
•Changes in utility regulation and the allocation of costs within RTOs including ERCOT, PJM and SPP.
•Changes in the creditworthiness of the counterparties with contractual arrangements, including participants in the energy trading market.
•Actions of rating agencies, including changes in the ratings of debt.
•The impact of volatility in the capital markets on the value of the investments held by the pension, OPEB, captive insurance entity and nuclear decommissioning trust and the impact of such volatility on future funding requirements.
•Accounting standards periodically issued by accounting standard-setting bodies.
•Other risks and unforeseen events, including wars and military conflicts, the effects of terrorism (including increased security costs), embargoes, cybersecurity threats, labor strikes impacting material supply chains, global information technology disruptions and other catastrophic events.
•The ability to attract and retain the requisite work force and key personnel.
