To Our Valued Shareholders,

When I joined AEP last year, I said leading this company was another opportunity of a lifetime, and after seven months in this role, my belief has not changed. I have had the privilege of talking with investors, employees, regulators, legislators and community leaders to learn more about AEP's challenges and opportunities. It is clear our company is full of potential, especially as we navigate once-in-a-generation load growth in our service territory. The key to seizing these opportunities is a relentless pursuit of excellence and a focus on doing what is right for our customers and states.

I am proud to share we made significant progress toward creating the energy system of the future and delivering on our promises to stakeholders last year:

• We announced a historic five-year, $54 billion capital plan and are evaluating up to an additional $10 billion investment to benefit customers and support growth in our service territory.

• Our commitment to economic development helped drive a 10.6% increase in commercial load growth last year.

• We announced that a strategic partnership between KKR and PSP Investments will acquire a 19.9% equity interest in our Ohio and Indiana Michigan Transcos for $2.82 billion. The proceeds will support our robust five-year capital plan, while allowing us to maintain a controlling 95% ownership of our industry-leading transmission assets.

• We shared plans to begin the early site permit process in Indiana and Virginia for two small modular reactors (SMRs) that will generate clean, reliable energy to support significant load growth in our service territory.

• We signed an agreement with Bloom Energy to secure up to 1 gigawatt (GW) of solid oxide fuel cells. This technology will provide data centers and other large customers with the energy they need to expand quickly as we continue to build infrastructure to deliver reliable service.

• We worked with regulators and large customers to ensure infrastructure costs to support increased demand are allocated fairly and provide benefits to all customers. We filed a unanimous settlement agreement with the interested parties in our Indiana large load case and have concluded the hearing process in Ohio. We received approval for our settlement agreement in Indiana and are waiting for a final order in Ohio.

• We continued to transform our generation fleet to meet the changing demands of our customers and states. We filed for approval for 2.3 GW of natural gas generation in PSO and SWEPCO and have active RFPs for new generation in Appalachian Power, I&M and PSO.

These accomplishments lay a strong foundation to create value and power growth in our communities. AEP has a long history of innovation and a reputation as an industry leader. I look forward to working with the team to drive best-in-class performance by honoring our past and shaping a clear vision of our future.

Thank you for your continued investment in this company and support of our work to improve customers' lives with reliable, affordable power.

Sincerely,

Bill Fehrman | President and Chief Executive Officer
