About the metric
What net income means
Net income is a company’s bottom-line profit or loss after operating costs, interest, taxes, and other reported income and expenses. It shows how much of a company’s revenue ultimately remained as earnings, or how large its loss was, during a fiscal period.
Calculation and source
SEC-reported net income
TickerStat standardizes consolidated net income or profit and loss reported in company SEC filings for aligned fiscal periods. It is not adjusted earnings, an analyst estimate, or company guidance. Fiscal periods can differ from calendar years, so exact period-end dates are included.
