# FirstEnergy: Business Model & Revenue Engine

## Direct Answer

FirstEnergy reports revenue across 3 product and service lines in its fiscal 2025 Form 10-K. Electricity Us Regulated is the largest, with $12.2 billion of revenue (81% of the total), followed by Electric Transmission at $2.3 billion (15%).

## How Does FirstEnergy Make Money?

Electricity Us Regulated supplies 81% of revenue, so FirstEnergy's results move mostly with that one business; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, Electric Worldwide Unregulated Revenue grew fastest (+69.5%) and Electric Transmission slowest (+7.6%), so the revenue mix tilts toward Electric Worldwide Unregulated Revenue while that gap lasts.

| Product or service | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Electricity Us Regulated | $12.2 billion | $11.0 billion | 80.8% | 11.1% |
| Electric Transmission | $2.3 billion | $2.1 billion | 15.3% | 7.6% |
| Electric Worldwide Unregulated Revenue | $590 million | $348 million | 3.9% | 69.5% |

## What the Segment Figures Do Not Show

The rows above add up to 100% of FirstEnergy's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.

## Where These Numbers Come From

Every figure on this page is a value FirstEnergy reported in the segment note and revenue disclosures of its Form 10-K filed February 18, 2026 (accession 0001031296-26-000046), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.

Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
