Direct Answer
DTE Energy reports revenue across 4 business segments in its fiscal 2025 Form 10-K. Electric is the largest, with $6.9 billion of revenue (44% of the total), followed by Energy Trading at $6.5 billion (41%).
How Does DTE Energy Make Money?
No single line supplies a majority of revenue: the largest, Electric, is 44%, which spreads DTE Energy's exposure across several demand drivers. Between fiscal 2024 and 2025, Energy Trading grew fastest (+68.5%) and DTE Vantage slowest (-7.6%), so the revenue mix tilts toward Energy Trading while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Electric | $6.9 billion | $6.3 billion | 43.9% | 10.2% |
| Energy Trading | $6.5 billion | $3.8 billion | 41.0% | 68.5% |
| Gas | $2.1 billion | $1.8 billion | 13.0% | 14.1% |
| DTE Vantage | $696 million | $753 million | 4.4% | -7.6% |
What the Segment Figures Do Not Show
The rows above add up to 102% of DTE 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 DTE Energy reported in the segment note and revenue disclosures of its Form 10-K filed February 17, 2026 (accession 0000936340-26-000054), 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.
