Customers
FirstEnergy serves regulated retail and wholesale electricity customers across several Mid-Atlantic and Midwest states, with the largest customer base in Ohio and Pennsylvania. Its customers include households, small businesses, large commercial and industrial users, and regulated transmission customers that pay formula-based rates. The company also serves default-service load where it must procure power and recover costs through approved rate mechanisms.

Strategy
FirstEnergy is focused on regulated grid investment, especially through its Energize365 capital program, which it recently increased for 2025. The company is also shifting toward a more efficient operating model, tighter cost discipline, and a stronger balance sheet to support long-cycle transmission and distribution spending. Its strategy emphasizes reliability, resiliency, cyber security, and selective regulated generation additions where state plans support investment recovery.
Supports rate base growth and long-term earnings in a utility model that depends on approved capital deployment.
Improves reliability and helps the company recover costs through regulated rates while reducing outage and weather risk.
Offsets inflation, supports credit metrics, and helps preserve returns in a heavily regulated business.
Adds regulated capacity where state resource plans support recovery and long-term system needs.
Geography
FirstEnergy's business is concentrated in the U.S. Northeast and Midwest, with regulated operations in Ohio, Pennsylvania, New Jersey, West Virginia, Maryland, and Virginia. Its transmission lines connect the Midwest and Mid-Atlantic regions, so geography matters both for customer density and for regulatory oversight by multiple state and federal bodies. The company also faces weather-driven demand swings, with electricity usage peaking in summer and winter across its service territories.
Risks
FirstEnergy's earnings are exposed to weather-driven demand swings, regulatory outcomes, and the timing of cost recovery under rate mechanisms. The company also faces litigation, FERC audit-related issues, credit risk from counterparties, and climate-related scrutiny tied to its emissions and infrastructure plans. Because it is a regulated utility, many risks are recoverable over time, but delays or disallowances can still affect cash flow, rate base, and investor returns.
- Seasonal weather and demand volatilityImpact: HighLikelihood: Medium
Electric sales peak in summer and winter, so mild weather can reduce power sales, revenue, earnings, and cash flow.
Exposure: Distribution and default-service load
- Regulatory and rate recovery riskImpact: HighLikelihood: Medium
Utility earnings depend on approval of rates and recovery of capital and operating costs through state and federal mechanisms.
Exposure - FERC audit and accounting/rate treatment riskImpact: HighLikelihood: Low
Audit findings can require reclassification of costs and create disputes over whether certain amounts remain in rate base.
Exposure: Transmission and corporate support cost allocations
- Climate and ESG-related scrutinyImpact: MediumLikelihood: Medium
Public commitments on carbon neutrality and infrastructure resilience can create reputational and compliance pressure if progress lags.
- Counterparty credit riskImpact: Medium
Power suppliers, utilities, and energy traders may default, forcing replacement purchases and potential working-capital strain.
Exposure
Accounting
Judgemental itemsDemand peaks in summer and winter, so revenue and cash flow can swing materially by quarter and weather pattern.
Impact: Quarterly comparability and liquidity
Transmission revenues are updated annually based on projected rate base and costs, with true-ups for actual results.
Impact: Revenue timing and regulatory asset/liability balances
Audit findings led to reclassification of certain transmission capital assets to operating expenses and disputes over rate-base treatment.
Impact: Operating expense, rate base, and recoverability
Lift-out transactions remove assets and liabilities from the plan and can reduce earnings volatility and balance-sheet exposure.
Impact: Other comprehensive income, liabilities, and expense volatility
