About the metric
What operating income means
Operating income is the profit or loss a company generates from its core business after cost of revenue and operating expenses, but before non-operating items such as interest and income taxes.
Calculation and source
SEC-reported operating income
TickerStat standardizes operating income reported in company SEC filings for aligned fiscal periods. It is not adjusted EBIT, an analyst estimate, or company guidance. Fiscal periods can differ from calendar years, so exact period-end dates are included.
