FIRSTENERGY CORP

11. SEGMENT INFORMATION

FirstEnergy

FE 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, February 13, 2026, MP and PE filed a CPCN to construct and operate the 1,200 MW combined cycle gas turbine plant, that will be known as Maidsville Energy Center, and the 70 MWs of solar generation capacity, each referenced in their integrated resource plan above, for an estimated capital investment totaling approximately $2.7 billion as of the date of the filing. See Note 9., “Regulatory Matters,” of the Combined Notes to Financial Statements of the Registrants for additional details.

FirstEnergy’s Stand-Alone Transmission segment, which consists of FE's ownership in FET and KATCo, includes transmission infrastructure owned and operated by the Transmission Companies and used to transmit electricity. The segment’s revenues are primarily derived from forward-looking formula rates, pursuant to which the revenue requirement is updated annually based on a projected rate base and projected costs, which is subject to an annual true-up based on actual rate base and costs. The segment’s results also reflect the net transmission expenses related to the delivery of electricity on FirstEnergy’s transmission facilities.

FirstEnergy’s Corporate/Other reflects corporate support and other costs not charged or attributable to the Electric Companies or Transmission Companies, including FE’s retained pension and OPEB assets and liabilities of former subsidiaries, interest expense on FE’s holding company debt and other investments or businesses that do not constitute an operating segment. Reconciling adjustments for the elimination of inter-segment transactions are shown separately in the following table of Segment Financial Information. Included in Corporate/Other for segment reporting is 67 MWs of generation capacity, representing AE Supply’s OVEC capacity entitlement. As of June 30, 2026, Corporate/Other had approximately $7.4 billion of external FE holding company debt.

JCP&L

As of January 1, 2026, JCP&L made changes in how management evaluates operating performance and allocates resources. As a result of these changes, JCP&L reassessed its operating segments and determined that its operations are now managed as a single integrated business. Historically, JCP&L reported two operating segments, Distribution and Transmission. Accordingly, JCP&L changed its external segment reporting to present its results, including comparative periods, as a single reportable segment for the first six months of 2026, and reclassified prior periods for comparability. There are no changes to JCP&L’s significant expenses, measure of profit or loss, or other segment items. Similarly, JCP&L’s goodwill reporting units were also changed to a single reporting unit as of January 1, 2026.

JCP&L’s Statements of Income and Comprehensive Income are consistent with the internal financial reports used by JCP&L's President, its CODM. JCP&L’s CODM uses net income to regularly assess performance, including considering actual versus budget variances to make operating decisions and allocate resources. JCP&L considers Other operating expenses, Provision for depreciation and Interest expense to be significant expenses. See JCP&L’s Statements of Income and Comprehensive Income. Total Assets are reported on the Balance Sheets and Capital investments are reported within Cash Flows from Investing on the Statement of Cash Flows.
