About the metric
What operating expenses mean
Operating expenses are the recurring costs of running a company’s business beyond the direct costs used to calculate gross profit. They commonly include selling, general and administrative expenses, research and development, and other operating costs.
Calculation and source
SEC-reported and calculated operating expenses
TickerStat uses operating expenses reported in company SEC filings when available. When a separate total is unavailable, it calculates operating expenses as aligned gross profit minus operating income for the same fiscal period. Fiscal periods can differ from calendar years, so exact period-end dates are included.
