Across 16 U.S. public companies in the coal industry, net profit is -2.1% of revenue, operating profit -4.0% and gross profit 14.9% (January 2026 data from NYU Stern). That gross margin ranks 87 of 94 industries.
The industry average is 13.0%, against 15.7% for the typical industry. A business above 13.0% keeps more of each sale than the listed companies in its field.
Listed companies in the coal industry trade at 10.4× EBITDA and 2.5× 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 8.4% 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 4.41 × 4.46% = 23.6%.
