# Williams Companies: Business Model & Revenue Engine

## Direct Answer

Williams Companies reports revenue across 4 business segments in its fiscal 2025 Form 10-K. Transmission Power Gulf is the largest, with $5.4 billion of revenue (46% of the total), followed by West at $2.8 billion (24%).

## How Does Williams Companies Make Money?

Between fiscal 2024 and 2025, Gas NGL Marketing Services grew fastest (+21.6%) and West slowest (+6.7%), so the revenue mix tilts toward Gas NGL Marketing Services while that gap lasts.

| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Transmission Power Gulf | $5.4 billion | $4.6 billion | 45.5% | 17.6% |
| West | $2.8 billion | $2.7 billion | 23.8% | 6.7% |
| Gas NGL Marketing Services | $2.2 billion | $1.8 billion | 18.2% | 21.6% |

## What the Segment Figures Do Not Show

The rows above add up to 106% of Williams Companies'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 Williams Companies reported in the segment note and revenue disclosures of its Form 10-K filed February 24, 2026 (accession 0000107263-26-000006), 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.
