Direct Answer
Generac reports revenue across 2 business segments in its fiscal 2025 Form 10-K. Domestic is the largest, with $3.5 billion of revenue (83% of the total), followed by International at $738 million (18%).
How Does Generac Make Money?
Domestic supplies 83% of revenue, so Generac's results move mostly with that one business; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, International grew fastest (+1.8%) and Domestic slowest (-2.9%), so the revenue mix tilts toward International while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Domestic | $3.5 billion | $3.6 billion | 83.0% | -2.9% |
| International | $738 million | $725 million | 17.5% | 1.8% |
What Does Generac Sell?
Generac also breaks revenue down by product and service line, which shows what customers pay for rather than how management organizes the business.
| Product or service | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Residential Power Products | $2.3 billion | $2.4 billion | 53.9% | -6.8% |
| Commercial and Industrial Power Products | $1.5 billion | $1.4 billion | 34.6% | 4.9% |
| Other Products and Services | $485 million | $473 million | 11.5% | 2.5% |
| Intersegment Sales | $62 million | $65 million | 1.5% | -3.4% |
What the Segment Figures Do Not Show
The rows above add up to 101% of Generac'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 Generac reported in the segment note and revenue disclosures of its Form 10-K filed February 18, 2026 (accession 0001437749-26-004568), 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.
