# NRG Energy: Business Model & Revenue Engine

## Direct Answer

NRG Energy reports revenue across 4 business segments in its fiscal 2025 Form 10-K. East is the largest, with $14.3 billion of revenue (46% of the total), followed by Texas at $11.1 billion (36%).

## How Does NRG Energy Make Money?

No single line supplies a majority of revenue: the largest, East, is 46%, which spreads NRG Energy's exposure across several demand drivers. Between fiscal 2024 and 2025, East grew fastest (+21.8%) and West and Other slowest (-16.2%), so the revenue mix tilts toward East while that gap lasts.

| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| East | $14.3 billion | $11.7 billion | 46.4% | 21.8% |
| Texas | $11.1 billion | $10.7 billion | 36.3% | 4.6% |
| West and Other | $3.2 billion | $3.8 billion | 10.4% | -16.2% |
| Vivint Smart Home Inc | $2.1 billion | $2.0 billion | 7.0% | 7.7% |

## Which NRG Energy Segments Earn the Most?

| Segment | FY2025 segment operating income | Segment margin |
| --- | --- | --- |
| East | $706 million | 4.9% |
| Texas | $1.1 billion | 10.0% |
| West and Other | $149 million | 4.7% |
| Vivint Smart Home Inc | $53 million | 2.5% |

Segment operating income is the profit measure NRG Energy reports to its chief operating decision maker for each segment. It usually leaves out corporate costs that are not allocated to a segment, so the segments usually add up to more than consolidated operating income, and margins are comparable within NRG Energy more safely than against another company.

## What the Segment Figures Do Not Show

The rows above add up to 100% of NRG Energy'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 NRG Energy reported in the segment note and revenue disclosures of its Form 10-K filed February 24, 2026 (accession 0001013871-26-000004), 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.
