Highest free-cash-flow-margin companies
Companies with the highest free-cash-flow margin — free cash flow as a share of revenue, a signal of cash-generative quality. Derived from SEC XBRL data where available; caps/REITs may legitimately lack it.
310 companies were left out of this ranking: 132 because the latest figure is from a fiscal year older than this ranking's window; 128 because a bank's or insurer's operating cash flow carries lending, deposit and claims-float flows, so it is not a free-cash-flow margin; 50 because profit larger than the revenue it is divided by — gains from outside revenue or a partial revenue line, not a margin.
Ranked by FCF margin, ANTERIX INC (ATEX) leads the covered catalog at +84.3%.
