Across 40 U.S. public companies in the construction supplies industry, net profit is 10.8% of revenue, operating profit 15.2% and gross profit 25.5% (January 2026 data from NYU Stern). That gross margin ranks 71 of 94 industries.
The industry average is 19.5%, against 15.7% for the typical industry. A business above 19.5% keeps more of each sale than the listed companies in its field.
Listed companies in the construction supplies industry trade at 16.8× EBITDA and 3.2× revenue. Small private businesses sell for far less: U.S. small businesses averaged 2.7× seller’s discretionary earnings in Q2 2026 (BizBuySell).
A diversified investor would want about 8.3% on the whole business (the industry cost of capital). An owner with most of their wealth in it carries more risk: 3.95% + total beta 2.82 × 4.46% = 16.5%.
