SEGMENT INFORMATIONThe disclosures in this note apply to both Registrants, unless indicated otherwise.FirstEnergyFE and its subsidiaries are principally involved in the transmission, distribution and generation of electricity through its reportable segments: Distribution, Integrated and Stand-Alone Transmission. The external reportable segments are consistent with the internal financial reports used by FirstEnergy's Chairman, President and Chief Executive Officer, its CODM, to regularly assess the performance of each segment. FirstEnergy’s CODM uses earnings attributable to FE from continuing operations to assess performance, including considering actual versus budget variances to make operating decisions and allocate resources to the segments. FirstEnergy's Distribution segment, which consists of the Ohio Companies and FE PA, distributes electricity through FirstEnergy’s electric operating companies in Ohio and Pennsylvania. The Distribution segment serves approximately 4.3 million customers in Ohio and Pennsylvania across its distribution footprint and purchases power for its default service or standard service offer requirements. The segment’s results reflect the costs of securing and delivering electric generation to customers, including the deferral and amortization of certain costs.FirstEnergy's Integrated segment includes the distribution and transmission operations of JCP&L, MP and PE, as well as MP’s regulated generation operations. The Integrated segment distributes electricity to approximately 2 million customers in New Jersey, West Virginia and Maryland across its distribution footprint; provides transmission infrastructure in New Jersey, West Virginia, Maryland and Virginia to transmit electricity and operates 3,610 MWs of regulated generation capacity located primarily in West Virginia and Virginia, which includes three solar generation sites, representing 30 MWs of generation capacity. The segment’s results reflect the costs of securing and delivering electric generation to customers, including the deferral and amortization of certain costs. Additionally, on October 1, 2025, MP and PE filed their integrated resource plan with the WVPSC proposing, among other things, the addition of 70 MWs of solar generation by 2028, and 1,200 MWs of natural gas combined cycle generation by 2031, which are expected to require an estimated capital investment of approximately $2.5 billion, as detailed in the filing. See Note 13.

REVENUEThe disclosures in this note apply to both Registrants, unless indicated otherwise.The Registrants account for revenues from contracts with customers under ASC 606, “Revenue from Contracts with Customers.” Revenue from leases, financial instruments, other contractual rights or obligations and other revenues that are not from contracts with customers are outside the scope of the standard and accounted for under other existing GAAP. The Electric Companies distribute electricity through FirstEnergy’s utility operating companies and also control 3,610 MWs of regulated electric generation capacity located primarily in West Virginia and Virginia. Each of the Electric Companies earns revenue from state-regulated rate tariffs under which it provides distribution services to residential, commercial and industrial customers in its service territory. The Electric Companies are obligated under the regulated construct to deliver power to customers reliably, as it is needed, which creates an implied monthly contract with the end-use customer. See Note 13., “Regulatory Matters,” of the Combined Notes to Financial Statements of the Registrants for additional information on rate recovery mechanisms. Distribution and electric revenues are recognized over time as electricity is distributed and delivered to the customer and the customers consume the electricity immediately as delivery occurs. Retail generation sales relate to Provider of Last Resort, SOS, Standard Service Offer and default service requirements in Ohio, Pennsylvania, New Jersey and Maryland, as well as generation sales in West Virginia that are regulated by the WVPSC. Certain of the Electric Companies have default service obligations to provide power to non-shopping customers who have elected to continue to receive service under regulated retail tariffs. The volume of these sales varies depending on the level of shopping that occurs. Supply plans vary by state and by service territory. Default service for the Ohio Companies, FE PA, JCP&L and PE’s Maryland jurisdiction are provided through a competitive procurement process approved by each state’s respective commission. Retail generation revenues are recognized over time as electricity is delivered and consumed immediately by the customer.Wholesale sales primarily consist of generation and capacity sales into the PJM market from FirstEnergy’s regulated electric generation capacity and NUGs.

STOCK-BASED COMPENSATION PLANSThe disclosures in this note apply to both Registrants, unless indicated otherwise.FirstEnergy grants, including to JCP&L employees, stock-based awards through the ICP 2020, primarily in the form of restricted stock, time-based RSUs and performance-based RSUs. No shares are available for future grants or issuance under ICP 2015. The ICP 2020 and ICP 2015 include shareholder authorization to each issue 10 million shares of common stock or their equivalent. Shares not issued due to forfeitures or cancellations originally granted through the ICP 2015 may be added back to the ICP 2020. As of December 31, 2025, approximately 7.4 million shares were available for future grants under the ICP 2020 assuming maximum performance metrics are achieved for the outstanding cycles of RSUs. Shares granted under the ICP 2020 are issued from authorized but unissued common stock. Vesting periods for stock-based awards range from less than a year, primarily due to the issuance of prorated awards to newly hired executives, to four years, with the majority of awards having a vesting period of three years. FirstEnergy also issues stock through its 401(k) savings plan and DCPD. FirstEnergy records the compensation costs for stock-based compensation awards that will be paid in stock over the vesting period based on the fair value on the grant date. FirstEnergy accounts for forfeitures as they occur. FirstEnergy adjusts the compensation costs for stock-based compensation awards that will be paid in cash based on changes in the fair value of the award as of each reporting date. FirstEnergy records the actual tax benefit realized from tax deductions when awards are exercised or settled. Actual income tax benefits realized during the years ended December 31, 2025, 2024 and 2023, were $7 million, $17 million and $6 million, respectively. The income tax effects of awards are recognized in the income statement when the awards vest, are settled or are forfeited.

LEASESThe disclosures in this note apply to both Registrants, unless indicated otherwise.The Registrants primarily lease vehicles as well as building space, office equipment, and other property and equipment under cancellable and non-cancelable leases. The Registrants do not have any material leases in which they are the lessor. The Registrants account for leases under, "Leases (Topic 842)". Leases with an initial term of 12 months or less are recognized as lease expense on a straight-line basis over the lease term and not recorded on the balance sheet. Most leases include one or more options to renew, with renewal terms that can extend the lease term from 1 to 40 years, and certain leases include options to terminate. The exercise of lease renewal options is at FirstEnergy’s sole discretion. Renewal options are included within the lease liability if they are reasonably certain based on various factors relative to the contract. Certain leases also include options to purchase the leased property. The depreciable life of leased assets and leasehold improvements are limited by the expected lease term unless there is a transfer of title or purchase option reasonably certain of exercise. The Registrants' lease agreements do not contain any material restrictive covenants. The Registrants have elected a policy to not separate lease components from non-lease components for all asset classes.For vehicles leased under certain master lease agreements, the lessor is guaranteed a residual value up to a stated percentage of the equipment cost at the end of the lease term. If the actual fair value of the leased equipment is below the guaranteed residual value at the end of the lease term, the Registrants are committed to pay the difference in the actual fair value and the residual value guarantee. The Registrants do not believe it is probable that it will be required to pay anything pertaining to the residual value guarantee, and the lease liabilities and right-of-use assets are measured accordingly.Finance leases for assets used in regulated operations are recognized in the Registrants' Statements of Income and Comprehensive Income such that amortization of the right-of-use asset and interest on lease liabilities equals the expense recorded for ratemaking purposes.

The FE Board has identified cyber security as a key enterprise risk and prioritizes the mitigation of this risk through FirstEnergy’s enterprise risk management process. Responsibility for oversight of risk management generally lies with the FE Board and the FE Audit Committee has primary responsibility to oversee enterprise risk management. To effectively manage oversight of FirstEnergy’s cyber security risk management practices, since 2022, the FE Board has delegated oversight authority to each of FirstEnergy’s Audit and Operations and Safety Committees, respectively, as detailed in each Committees’ charters. The Audit Committee has primary responsibility to oversee the disclosure of material cyber security incidents, as well as the general obligation to ensure the proper risk oversight structure of cyber security as part of FirstEnergy’s overall enterprise risk management program and the internal controls applicable to cyber security matters. The Operations and Safety Oversight Committee has primary responsibility to oversee the operational aspects of FirstEnergy’s cyber security policies, programs, initiatives and strategies, as well as operational risk considerations related to cyber security matters. FirstEnergy’s Cyber Security Leaders regularly provide reports at the Audit Committee, Operations and Safety Oversight Committee, and to the full FE Board. Each such Committee and the full FE Board work collaboratively to ensure fulsome oversight with the proper focus of each respective Board body. These reports include, among other things, current and emerging cyber security risks to FirstEnergy, incidents that were escalated to management during the prior quarter, including those that did not require immediate escalation to the appropriate Committee and/or full FE Board, internal and external assessments of FirstEnergy’s cyber security program, and a roadmap of projects to manage its cyber security posture.At the executive and management level, the CISO has primary responsibility for the development, operation, and maintenance of FirstEnergy’s cyber security program. FirstEnergy's CISO has over 30 years of cyber-experience with both large domestic and international companies, and holds an ISC2 Certified Information Systems Security Professional certification.

TAXES The disclosures in this note apply to both Registrants, unless indicated otherwise.The Registrants record income taxes in accordance with the liability method of accounting. Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts recognized for tax purposes. Investment tax credits, which were deferred when utilized, are being amortized over the recovery period of the related property. Deferred income tax liabilities related to temporary tax and accounting basis differences and tax credit carryforward items are recognized at the statutory income tax rates in effect when the liabilities are expected to be paid. Deferred tax assets are recognized based on income tax rates expected to be in effect when they are settled.FE and its subsidiaries, other than FET and its subsidiaries, are parties to an intercompany income tax allocation agreement that provides for the allocation of consolidated tax liabilities. For periods subsequent to the closing of the FET Equity Interest Sale, FET and its subsidiaries are no longer members of the FirstEnergy consolidated group for federal income tax purposes and, instead, file their own consolidated federal income tax return and have their own income tax allocation agreement.During 2025, FERC issued orders to a non-affiliate concluding that, based on certain previously issued IRS private letter rulings, certain NOL carryforward deferred tax assets, as computed on a separate return basis, should be included in rate base for ratemaking purposes. FirstEnergy determined in the third quarter of 2025 that these rulings and orders also would apply to certain of its subsidiaries, resulting in a benefit from a reduction in regulatory liabilities, reflected as the remeasurement of excess deferred income taxes, and an increase in accumulated deferred income tax assets for ratemaking purposes, which will increase overall rate base. FirstEnergy made the appropriate updates in its annual formula rates for the impacted subsidiaries. FirstEnergy will continue to evaluate whether regulatory filings are required in other jurisdictions to implement similar adjustments to NOL carryforward deferred tax assets for ratemaking purposes.
