INTRODUCTIONAt AEP our path to a clean energy economy is clear as we continue to diversify our generation portfolio and invest in a modern grid capable of optimizing all resources and technologies We have made good progress in reducing our carbon footprint and delivering clean energy solutions to our customers While our strategy for the future is unchanged the world around us has changed significantly As we adapt to new norms from a public health crisis and confront the social justice divisions in our society our resolve that a clean energy future has a place for everyone is stronger than ever

AEP 2020 EEI ESGSustainability Report 3

The pandemic and civil unrest have underscored the importance of nonfinancial risks that we must weigh as we execute our strategy For example our priority to protect our employees from harm heightened as we pivoted to new ways of doing our work expanded benefits for frontline workers and took measures to reduce exposure while enabling thousands of employees to work remotely At the same time social and racial inequities are shining a spotlight on our focus to achieve our goals for diversity and inclusion While AEP continued to support its communities to meet basic human needs during the pandemic we also took a public stand against racism including supporting a local resolution designating racism as a public health crisis AEP believes that everyone should feel welcomed valued and treated with dignity and respect Not just at our company but everywhere

In spite of the challenges before us we remain optimistic about our ability to balance and meet the needs of our customers investors and communities as we continue to execute our strategy

GOVERNANCE RISK MANAGEMENT amp STRATEGY

In 2019 the fast-paced growth of ESG investing prompted an expanded and more granular focus on how we manage AEPrsquos ESG performance and disclosure We established a cross-functional ESG Team to monitor new and emerging ESG issues and develop strategies for responding to them Because ESG performance is also a business risk it has been added to our risk summary report and we are integrating it with our corporate strategy

The Committee on Directors and Corporate Governance of the Board of Directors reviews the Corporate Accountability Report (CAR) annually and monitors AEPrsquos ESG performance The Committee provides feedback and the Lead Director authors a Board Statement supporting AEPrsquos commitment to sustainable business development and performance accountability The combined governance from the Board of Directors executive management the ESC and its ESG committee helps us ensure our disclosure undergoes a disciplined review and validation process In addition the Lead Director of AEPrsquos Board of Directors conducts an annual outreach with our largest shareholders to engage with investors on corporate governance issues including ESG matters

Cyber GovernanceThe cyber and physical security of the bulk electric system (BES) is highly regulated by the federal government through the North American Electric Reliability Corporation (NERC) Critical Infrastructure Protection (CIP) Reliability Standards To ensure that our security controls are comprehensive effective and in compliance with regulatory requirements we have established a robust collaborative security policy management program that aligns with the National Institute of Standards and Technology (NIST) Cybersecurity Framework Our resulting policies and standards are jointly developed with AEPrsquos business units through the Enterprise Security Advisory Council to maximize adoption and implementation of standard controls thereby reducing security risk to AEP

NERC Compliance amp GovernanceThe growing reality of cyber and physical threats to our industryrsquos infrastructure is raising concerns with regulators and customers alike As a result the Federal Energy Regulatory Commission (FERC) is driving the NERC to develop unparalleled regulations for our industry These regulations protect the grid and keep it safe reliable and secure Our challenge is that the regulations are constantly evolving and new rules continue to be issued NERCrsquos CIP Standards reflect the growing focus on protecting the grid from cyber threats

AEPrsquos NERC compliance governance structure was developed specifically to respond to the current compliance environment and provides the direction agility and organizational support needed to implement an industry-leading NERC compliance program This governance structure in collaboration with regulators and industry leaders has resulted in the implementation of a three-year strategic plan for achieving operational excellence in NERC compliance In addition AEPrsquos safety culture provides a strong foundation for ensuring that compliance is one of the essential elements of the programrsquos strategic plan Every employee at AEP has a role in delivering reliable safe secure electricity to all of our customers and compliance plays a critical role in achieving this goal

Managing RiskAt AEP managing risk is layered and targeted to identify and manage risks across the enterprise AEPrsquos Enterprise Risk amp Resiliency team works with business units and operating companies to proactively identify assess mitigate and manage risks The team which is comprised of the Enterprise Risk Oversight (ERO) Crisis Response and Enterprise Business Continuity amp Resiliency (EBCR) teams helps AEP better understand the full picture of each risk and the disruptions it can cause

ERO defines and oversees the consistent application of AEPrsquos risk management process in conjunction with our business units and operating companies This helps us identify strategic financial operational and regulatory risks assess the threats and controls evaluate the risk plan mitigation strategies and monitor risks for changing conditions

The Chief Risk Officer reports a summary view of risks to the Risk Executive Committee which consists of senior leaders to illustrate risk ranking and remediation dates and ultimately gain consensus on an action plan This summary is then discussed and reviewed by the Audit Committee of the Board of Directors AEP monitors risks associated with ESG and climate change through this same process

AEPrsquos Crisis Response team is responsible for the ongoing development and maintenance of emergency response plans and the associated strategies and actions to address our response to an event Well-planned and executed responses can reduce the impacts to AEP and to our customers shareholders and communities we serve

The EBCR team defines and oversees AEPrsquos business continuity process and supports our business units and operating companies in planning and preparation Plans are developed and tested to continuously improve our ability to effectively respond and recover in the event of an emergency

The risk of a cyberattack is an example of a risk that could interrupt business operations and affect several of our core assets In 2019 AEP strengthened its integrated cyber response plan which defines various levels of an event and uses an Incident Command System (ICS) structure to outline roles and responsibilities for response personnel The plan brings various business units from across the enterprise into a single unified response and organizational reporting structure if a cyber-incident were to occur We have conducted exercises through enterprise tabletop incident simulations to test the plan The ICS structure is also used for other crisis events including the coronavirus pandemic Learn more about AEPrsquos response to the COVID-19 pandemic

StrategyOur strategy for a clean energy future is on course We are building a modern grid that is scalable to support the demand for more electricity from electrification such as electric vehicles and data centers while preparing for other future power needs We are expanding our fiber optics network to meet the data needs of an increasingly digital smart grid It also supports opportunities to enable internet service providers to make the final connection to areas that lack broadband coverage that helps underserved areas ndash providing access to jobs healthcare food and education We have strategic

NERC Compliance amp GovernanceThe growing reality of cyber and physical threats to our industryrsquos infrastructure is raising concerns with regulators and customers alike As a result the Federal Energy Regulatory Commission (FERC) is driving the NERC to develop unparalleled regulations for our industry These regulations protect the grid and keep it safe reliable and secure Our challenge is that the regulations are constantly evolving and new rules continue to be issued NERCrsquos CIP Standards reflect the growing focus on protecting the grid from cyber threats

AEPrsquos NERC compliance governance structure was developed specifically to respond to the current compliance environment and provides the direction agility and organizational support needed to implement an industry-leading NERC compliance program This governance structure in collaboration with regulators and industry leaders has resulted in the implementation of a three-year strategic plan for achieving operational excellence in NERC compliance In addition AEPrsquos safety culture provides a strong foundation for ensuring that compliance is one of the essential elements of the programrsquos strategic plan Every employee at AEP has a role in delivering reliable safe secure electricity to all of our customers and compliance plays a critical role in achieving this goal

collaborations with start-ups and other partners to explore and pilot an array of technologies so that we can accelerate our goal of being the digital clean energy company of the future At the same time we are achieving significant reductions in carbon emissions

We are committed to operational excellence financial discipline innovation and technology and being nimble as we adapt to a changing world AEPrsquos record of consistent earnings and dividend growth a strong balance sheet and our focus on our customers and communities is essential to our mission

Before the onset of the pandemic AEP began taking steps to reduce its costs and we are accelerating those plans Our Achieving Excellence program will help us to be more efficient and strategic as we manage costs for our customers

Carbon amp ClimateAEP continues to move forward with its transition to a clean energy future Through 2019 AEP reduced its carbon emissions by 65 compared with a 2000 baseline We are shrinking our carbon footprint by diversifying our resource portfolio deploying technologies to mitigate risk modernizing the power grid and working with our industry peers to achieve a low- to no-carbon future Climate change remains a significant risk for AEP but also presents new business opportunities that we continue to explore

In 2020 we began a comprehensive climate change scenario analysis consistent with the Task Force for Climate-related Financial Disclosures (TCFD) framework We expect to publish a new clean energy report that will include our findings by the end of the year

In 2019 we revised our carbon emission reduction goals because we had already achieved significant progress ahead of schedule This was largely due to lower use of coal generation accelerated by falling natural gas prices and the growth of subsidized renewables with zero fuel cost Our new 2030 goal calls for a 70 reduction and our 2050 goal calls for an 80 reduction both from a 2000 baseline We expect that we will exceed the 80 goal and achieve larger reductions and our aspiration remains zero We committed to reviewing these goals annually as public policies regulations resource plans and advanced technologies evolve
