Figures in USD. Free cash flow is operating cash flow less capital expenditure; owner earnings take off only the spending that keeps the business as it is, not the spending to grow it (an estimate by Financial Modeling Prep). Quarterly growth is on the same quarter a year before; TTM is the last four quarters.
