Frequently asked questions

What is IOSP's profit margin?
In FY2025, gross margin was 27.7%, operating margin 7.3%, and net margin 6.6%.
What is IOSP's P/E ratio?
Innospec Inc.'s P/E (TTM) is 21.04 as of the 2026-11-02 close — market cap ÷ net income over the trailing twelve months where four consecutive quarters are reported, otherwise the latest fiscal year, the same figure as on the IOSP stock page. The valuation chart above sets each month-end's price against the latest annual net income instead, so its latest point (about 21.0× as of Nov '26) can differ. These are computed facts, not advice.
Where does this data come from?
All figures are extracted from the company’s SEC EDGAR/XBRL filings — 10-K annual reports and 10-Q quarterly reports (use the Annual / Quarterly toggle). Quarterly figures are derived from the as-filed statements (year-to-date amounts are differenced into discrete quarters). Growth rates and ratios are computed by tradmap; nothing here is investment advice.
