* Worked out from the filings rather than stated in them: Q4 is the full year less the first nine months.
Per-share figures and share counts are restated for stock splits the filings show: 1-for-25, first reported Aug 13, 2024.
EPS growth is left out where the share count moved enough to suggest a split the filings do not show. Growth rates need a positive starting figure. CAGR is compound annual growth between fiscal years. The CSV holds every period on file, in full figures, from the same SEC filings.
