Operating margin (Op mgn)
What is left of each unit of revenue after every cost of running the business, before interest and tax.
It is the profitability of the operation itself, stripped of how it is financed and where it is taxed.
How it is computed here
Operating income / revenue x 100
Combines more than one basis. See the note. The pipeline prefers the data vendor's published trailing-twelve-month ratio when one exists, and falls back to recomputing from the latest filed fiscal year when it does not. Those two are different measurements: the vendor figure puts twelve months of flow over the most recent quarterly balance sheet. The source trail on each figure names which path produced it. Filed under quality. Higher is the stronger reading, other things equal.
No published threshold exists for this figure, so this page prints none. Read it against the company's own history and its peers instead.
When it misleads
- There is no cross-industry threshold worth printing. The peer percentile against companies in the same industry is the only defensible reading.
- The stored figure prefers the vendor trailing-twelve-month ratio when one is published, so it can differ from a recompute off the latest annual statements. The source trail shows both.
- A single year is not evidence. Read it against the full filed history above before it changes your mind about anything.
