Top 100 Stocks by Operating Margin

What Operating Margin Means for US-listed Companies

Operating margin is operating income divided by revenue, so it captures what is left of each sales dollar after both the direct costs of making the product and the indirect costs of running the business, including sales, research, overhead, and depreciation, have been absorbed. It sits below gross margin and above net margin on the income statement, reading the pure operating engine of the firm without interference from capital structure or tax jurisdiction.

Why Operating Margin Alone Can Mislead

Operating margin is powerful because it isolates how efficiently a business converts revenue into profit from operations, before financing choices skew the picture. That said, it is highly sector-dependent, which makes cross-industry comparisons misleading without context. It also embeds depreciation, a non-cash charge tied to past capex, so capital-heavy firms can look weaker than their cash economics suggest. Accounting choices about what to capitalize and one-time restructuring charges further distort single-year snapshots.

What to Read Alongside

Pair operating margin with Gross Margin to see where the profit is being earned or lost in the cost stack, Net Margin for the after-tax bottom-line read, and EBITDA to strip out the depreciation effect.
