How Does Willis Towers Watson Rank Among All SEC Filers in Its Industry Code?
16 companies with annual reports in Swoopr's SEC dataset share SIC code 6411 (Insurance Agents, Brokers & Service), a wider group than the S&P 500 Equal Weight companies above. Ranks run from 1 (highest) and use each company's latest fiscal year, in U.S. dollars.
| Measure | Willis Towers Watson | Median of filers | Rank |
|---|---|---|---|
| Revenue | $9.7 billion | $1.5 billion | 4 of 16 |
| Revenue growth | -2.2% | 16.4% | 14 of 16 |
| Operating margin | 23.0% | 14.9% | 2 of 11 |
| Net margin | 16.5% | 8.7% | 4 of 16 |
A SIC code reflects the filer's main business as the SEC records it, so the group mixes companies of very different size; the median is a better guide than the average, and a rank near the top by revenue says nothing about quality.
Where These Numbers Come From
Every figure on this page is a value Willis Towers Watson reported in its own SEC filings, read from the SEC's XBRL data (accession 0001193125-26-069307 for fiscal year 2025). Ratios are computed from those reported values. Figures were retrieved on October 12, 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.
