How we calculate: values as first reported to the SEC (later corrections are left out), a fixed order of reporting tags per figure, partial sums are never added up. Growth per year Growth per year (CAGR)The average annual growth rate over several years, as if the value had grown equally strongly every year. Individual good or bad years even out in it.Example: Revenue €100m → €161m in 5 years → (161 ÷ 100) to the power of 1/5 − 1 = 10% per year.More in the Academy: Lesson debt, dividends and growth over 5 years (otherwise 3 years). Quarters are labeled by the calendar quarter in which they end.
