# Generac: Competitors & Industry Structure

## Direct Answer

SEC EDGAR classifies Generac under SIC code 3621 (Motors & Generators). Among Swoopr's S&P 500 Equal Weight companies, 2 others share that classification; by latest reported revenue, Generac ranks 1 of 3. A filing classification is a starting point: a company's real competitors depend on its segments, which its 10-K describes.

## How Does Generac Compare With Its Peers?

| Company | Revenue (latest FY) | Revenue growth | Operating margin | Net margin |
| --- | --- | --- | --- | --- |
| **Generac (GNRC)** | $4.2 billion FY2025 | -2.0% | 6.9% | 3.8% |
| [American Superconductor Corporation (AMSC)](https://www.getswoopr.com/stocks/companies/american-superconductor-corporation/) | $299 million FY2026 | 34.3% | 3.8% | 44.7% |
| [374Water Inc. (SCWO)](https://www.getswoopr.com/stocks/companies/374water-inc/) | $215,037 FY2025 | -51.7% | -9834.2% | -9754.2% |

Revenue growth compares each company's latest fiscal year with the one before. Fiscal years do not always end on the same date, so treat close comparisons with care.

## Where These Numbers Come From

Every figure on this page is a value Generac reported in its own SEC filings, read from the SEC's XBRL data (accession 0001437749-26-004568 for fiscal year 2025). Ratios are computed from those reported values. Figures were retrieved on October 7, 2026; a later amendment or a new annual report can change them, and the filing itself always takes precedence over this summary.

Each fiscal year is labeled by the calendar year in which it ended, so a company that names the same period differently in its own filings (many retailers whose year ends in January) may use another label. A year is left out of the table when the SEC data set holds no value for it. A figure shown as "Not reported" means the company did not file a value under the standard tag Swoopr reads, not that the amount was zero. This page is educational and describes reported history only; it is not a forecast or a recommendation.

## Frequently Asked Questions

### Who are Generac's competitors?

Companies sharing Generac's SEC classification (SIC code 3621 (Motors & Generators)) include American Superconductor Corporation (AMSC), 374Water Inc. (SCWO). Its 10-K names the competitors it considers most relevant.

### How does Generac compare with its peers on margins?

### How are these peers chosen?

By the SEC Standard Industrial Classification code each company files under, within Swoopr's S&P 500 Equal Weight company set, falling back to the two-digit major group when fewer than two companies share the exact code. Classification codes are broad, so read the peer list as a screen, not a verdict.
