Among Swoopr's S&P 500 Equal Weight companies, 4 others share that classification; by latest reported revenue, Builders FirstSource ranks 3 of 5.

Select the chart to open it full size.* ## How Does Builders FirstSource Rank Among All SEC Filers in Its Industry Code? 5 companies with annual reports in Swoopr's SEC dataset share SIC code 5211 (Retail-Lumber & Other Building Materials Dealers), 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 | Builders FirstSource | Median of filers | Rank | | --- | --- | --- | --- | | Revenue | $15.2 billion | $15.2 billion | 3 of 5 | | Revenue growth | -7.4% | 3.1% | 4 of 5 | | Operating margin | 5.2% | 5.8% | 4 of 5 | | Net margin | 2.9% | 4.5% | 4 of 5 | 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 Builders FirstSource reported in its own SEC filings, read from the SEC's XBRL data (accession 0001193125-26-054643 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. ## Frequently Asked Questions ### Who are Builders FirstSource's competitors?
