The highest GAAP operating margin
GAAP operating margin
Ranked from the filings of the
companies this site has read, under
Quality.
50 of them report a figure for this; the rest are absent rather than
ranked last, because a filing that does not carry a number is not a company that scores
badly on it.

How this measure is worked out
Operating income ÷ revenue × 100
Operating income (also called EBIT) is what is left of sales after the cost of the product and the cost of running the company, before interest and tax. Revenue is total sales to customers before any cost is taken off. Both over the trailing twelve months.
50% earns a 10; set margin_scale per ticker for sectors that cannot reach it

What this ranking is not
It is not advice, and a high place is not a recommendation. A company can lead on one
measure and fail on every other; that is the reason this site scores five dimensions
rather than one and lets you weigh them yourself.
It also ranks only what has been read. A company whose filings are not in this database
cannot appear here however well it would have done, and a company whose filing does not
tag this figure is absent rather than last.
Worked out on 2026-09-27.
