# American Electric Power: Business Model & Revenue Engine



## Direct Answer

American Electric Power reports revenue across 4 product and service lines in its fiscal 2025 Form 10-K. Electricity is the largest, with $12.6 billion of revenue (57% of the total), followed by Transmission and Distribution Utilities Revenues at $6.1 billion (28%).

## How Does American Electric Power Make Money?

No single line supplies a majority of revenue: the largest, Electricity, is 57%, which spreads American Electric Power's exposure across several demand drivers. Between fiscal 2024 and 2025, Generation and Marketing Revenues grew fastest (+38.7%) and Transmission and Distribution Utilities Revenues slowest (+3.7%), so the revenue mix tilts toward Generation and Marketing Revenues while that gap lasts.

| Product or service | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Electricity | $12.6 billion | $11.4 billion | 57.4% | 10.0% |
| Transmission and Distribution Utilities Revenues | $6.1 billion | $5.9 billion | 27.9% | 3.7% |
| Generation and Marketing Revenues | $2.7 billion | $1.9 billion | 12.3% | 38.7% |
| Product and Service Other | $526 million | $482 million | 2.4% | 9.1% |

## What the Segment Figures Do Not Show

The rows above add up to 100% of American Electric Power'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 American Electric Power reported in the segment note and revenue disclosures of its Form 10-K filed February 12, 2026 (accession 0000004904-26-000013), 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.
