# CMS Energy: Business Model & Revenue Engine



## Direct Answer

CMS Energy reports revenue across 3 business segments in its fiscal 2025 Form 10-K. Electric Utility is the largest, with $5.6 billion of revenue (66% of the total), followed by Gas Utility at $2.5 billion (29%).

## How Does CMS Energy Make Money?

Electric Utility supplies 66% of revenue, so CMS Energy's results move mostly with that one business; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, North Star Clean Energy grew fastest (+29.1%) and Electric Utility slowest (+11.4%), so the revenue mix tilts toward North Star Clean Energy while that gap lasts.

| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Electric Utility | $5.6 billion | $5.1 billion | 66.0% | 11.4% |
| Gas Utility | $2.5 billion | $2.1 billion | 29.2% | 16.6% |
| North Star Clean Energy | $408 million | $316 million | 4.8% | 29.1% |

## Which CMS Energy Segments Earn the Most?

| Segment | FY2025 segment operating income | Segment margin |
| --- | --- | --- |
| Electric Utility | $1.1 billion | 19.5% |
| Gas Utility | $671 million | 26.9% |
| North Star Clean Energy | -$28 million | -6.9% |

Segment operating income is the profit measure CMS 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 CMS Energy more safely than against another company.

## What the Segment Figures Do Not Show

The rows above add up to 100% of CMS 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 CMS Energy reported in the segment note and revenue disclosures of its Form 10-K filed February 10, 2026 (accession 0000811156-26-000004), 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.
