Earnings per share comes from Yahoo Finance where available, then Alpha Vantage or the company release. Revenue comes from company releases, SEC filings, Alpha Vantage or Yahoo Finance. A beat or miss needs an analyst estimate on the same basis as the reported figure, so quarters without one show none. Non-USD amounts carry their currency code.
