1Q 2020 Strategic & Financial Highlights Charles E. Jones, President and CEO Steven E. Strah, SVP and CFO April 24, 2020

Non-GAAP Financial Matters This presentation contains references to non-GAAP financial measures including, among others, Operating earnings (loss), Operating earnings (loss) per share and Operating earnings (loss) per share by segment. Generally, a non-GAAP financial measure is a numerical measure of a company’s historical or future financial performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with accounting principles generally accepted in the United States (GAAP). Operating earnings (loss), Operating earnings (loss) per share and Operating earnings (loss) per share by segment are not calculated in accordance with GAAP to the extent they exclude the impact of “special items.” Special items represent charges incurred or benefits realized that management believes are not indicative of, or may obscure trends useful in evaluating the company’s ongoing core activities and results of operations or otherwise warrant separate classification. Special items also reflect the adjustment to include the full impact of share dilution from the $2.5 billion equity issuance in January 2018. Special items are not necessarily non-recurring. FirstEnergy Corp. (FE or the Company) management cannot estimate on a forward-looking basis the impact of these items in the context of Operating earnings (loss) per share growth projections because these items, which could be significant, are difficult to predict and may be highly variable. Consequently, the Company is unable to reconcile Operating earnings (loss) per share growth projections (i.e. CAGR) to a GAAP measure without unreasonable effort. Operating earnings (loss) per share and Operating earnings (loss) per share for each segment is calculated by dividing Operating earnings (loss), which excludes special items as discussed above, for the periods presented in 2019 by 539 million shares, 542 million shares in 2020 and 541 million shares in the first quarter of 2020, which reflects the full impact of share dilution from the equity issuance in January 2018. Management uses non-GAAP financial measures such as Operating earnings (loss) and Operating earnings (loss) per share to evaluate the company’s performance and manage its operations and frequently references these non-GAAP financial measures in its decision-making, using them to facilitate historical and ongoing performance comparisons. Additionally, management uses Operating earnings (loss) per share by segment to further evaluate the company’s performance by segment and references this non-GAAP financial measure in its decision-making. Management believes that the non-GAAP financial measures of Operating earnings (loss), Operating earnings (loss) per share and Operating earnings (loss) per share by segment provide consistent and comparable measures of performance of its businesses on an ongoing basis. Management also believes that such measures are useful to shareholders and other interested parties to understand performance trends and evaluate the company against its peer group by presenting period-over-period operating results without the effect of certain charges or benefits that may not be consistent or comparable across periods or across the Company’s peer group. All of these non-GAAP financial measures are intended to complement, and are not considered as alternatives to, the most directly comparable GAAP financial measures. Also, the non-GAAP financial measures may not be comparable to similarly titled measures used by other entities. Pursuant to the requirements of Regulation G, FirstEnergy has provided, where possible without unreasonable effort, quantitative reconciliations within this presentation of the non-GAAP financial measures to the most directly comparable GAAP financial measures. 2 April 24, 2020

Business Updates – COVID-19 Operational Impacts ■ We believe our fully regulated strategy is built for resiliency during this crisis and we are well- positioned to manage through these events – Diversity and scale of our T&D operations is a fundamental strength (65,000 square miles across five states) ■ We operate critical infrastructure, and that means everything our employees do is considered essential work – #1 priority is to help keep our employees, their families, and our customers safe ■ We’ve taken significant steps to adapt and protect the health of our employees and customers – Successfully transitioned more than 7,000 employees to work remotely; more than half of our workforce – For our workforce unable to work remotely, implemented numerous preventative safety measures, including:  Protective equipment and other supplies (i.e. surgical masks, thermometers)  Increased cleaning and disinfecting measures  Relocated job briefs and reporting locations to sites conducive to social distancing  Adjusted work schedules and instituted small work groups we call “pods”  Minimizing potential exposure with the public ■ We remain flexible to meet the ongoing needs of our workers, minimize the spread of this virus, and adopt the current guidance from state and federal health agencies We intend to emerge from this stronger; we've come together to learn how to work smarter, more creatively and more efficiently 3 April 24, 2020

Business Updates – COVID-19 (continued) Financial Considerations ■ Our T&D investments will continue to provide stable and predictable earnings – Diversity and scale gives us the flexibility to shift our investments, if needed, and continue deploying capital throughout the system; do not anticipate significant disruptions to our supply chain ■ From mid-March until mid-April vs. same period last year, system-wide, weather-adjusted load is down by almost 6% – Based on PA smart meter data, RES load increase more than 6%; driven by the Stay At Home order – Expect similar increases in RES usage across our service territory driven by Stay At Home orders in all of our states – COM and IND load decrease of almost 13% when compared to our prior 4-year average ■ However, our rate structures provide a measure of stability, even in tumultuous times 2019 Base Distribution Revenues: % Breakdown of Base Distribution Revenues Significant % Non-Volume Based Billing 65% RES 28% COM 7% IND 9% 59% 19% 44% Volumetric 81% 91% Fixed 41% 56% ~20% of total retail load is decoupled (Ohio) RES COM IND Total – Pleased that the MD PSC proactively issued an order, authorizing deferral, for future recovery, of all prudent, incremental COVID-19 related costs – We can also recover incremental uncollectible expenses through existing riders in Ohio and New Jersey ■ Our regulatory calendar is light through our 2023 planning period We are very well-positioned to manage the impact of the economic slowdown 4 April 24, 2020

Business Updates (continued) Regulatory Calendar ■ In February, filed distribution base rate case in New Jersey – Seeking to recover increasing costs associated with providing safe and reliable electric service for our customers, along with recovery of storm costs incurred over the last few years – We expect an ALJ will be assigned to our case soon, followed by the issuance of a procedural schedule – In the meantime, the discovery phase has begun for parties to review the details of our request – We anticipate the litigation schedule will provide the opportunity to discuss favorable settlement with the parties in the case ■ Earlier in April, reached an agreement to transfer JCP&L’s portion of the Yard’s Creek plant to LS Power – Expect that transaction to close in the first half of 2021, pending approvals ■ In West Virginia, required to file our Integrated Resource Plan (IRP) by December 30, 2020 – Updates our plan to provide our WV customers with adequate and reliable generation resources that reasonably balance cost and risk ■ At Potomac Edison-Maryland, commitment to file a rate case by early 2023 5 April 24, 2020

Earnings Drivers: 1Q 2020 vs. 1Q 2019 Regulated Distribution (RD) ▪ Distribution Revenues: Distribution revenues decreased earnings $0.01 per share, primarily due to $0.07 from lower weather-related usage, partially offset by $0.04 per share benefit from implementing decoupling in Ohio and $0.02 per share from incremental rider revenues in Ohio and Pennsylvania. Q-o-Q Weather-Adjusted Distribution Deliveries Q-o-Q Actual Distribution Deliveries (1.3)% (3.0)% (1.6)% (1.7)% (7.5)% (7.8)% (2.2)% (12.6)% Residential Commercial Industrial Total Residential Commercial Industrial Total ▪ Absence of Ohio DMR: Absence of earnings contribution from the Ohio Distribution Modernization Rider (DMR), which ended on July 2, 2019, decreased earnings $0.06 per share. ▪ Net Operating and Miscellaneous Expenses: Lower O&M and miscellaneous expenses increased earnings $0.02 per share. ▪ Depreciation: Higher depreciation expense decreased earnings $0.01 per share, primarily due to a higher asset base. ▪ Net Financing Costs: Interest on new debt financings decreased earnings $0.01 per share. ▪ Special Items: In the first quarter of 2020 and 2019, special items totaled $0.29 per share and ($0.01) per share, respectively. Regulated Transmission (RT) ▪ Transmission Margin: Higher transmission margin increased earnings $0.03 per share, primarily due to higher rate base at Mid-Atlantic Interstate Transmission, LLC (MAIT) and American Transmission Systems, Incorporated (ATSI). ▪ Net Financing Costs: Interest on new debt financings decreased earnings $0.01 per share. ▪ Other: Other/Segment Rounding increased earnings $0.01 per share.

Special Items Descriptions ▪ Regulatory charges: Primarily reflects the impact of regulatory agreements or orders requiring certain commitments and/or disallowing the recoverability of costs, net of related credits. ▪ Exit of competitive generation: Primarily reflects charges or credits resulting from the exit of competitive operations and impairments of certain non-core assets, including the impact of deconsolidating FES, its subsidiaries and FENOC, following their voluntary petitions for bankruptcy protection on March 31, 2018. ▪ Mark-to-market adjustments - Pension/OPEB actuarial assumptions: Reflects the change in fair value of plan assets and net actuarial gains and losses associated with the company's pension and other post-employment benefit plans. ▪ Impact of full dilution: Represents the dilutive impact of increasing weighted average shares outstanding to reflect the full impact of share dilution from the $2.5 billion equity issuance in January 2018, including preferred dividends and conversion of preferred stock to common shares. Note: Special items represent charges incurred or benefits realized, including share dilution, that management believes are not indicative of, or may obscure trends useful in evaluating the company’s ongoing core activities and results of operations or otherwise warrant separate classification. Special items are not necessarily non-recurring. 14 April 24, 2020
