EPS and the estimate come from Yahoo Finance’s earnings calendar, captured around the report date. That EPS is the adjusted figure analysts forecast, so it can differ from the GAAP diluted EPS in the company’s filing, and consensus estimates vary between data providers. Revenue comes from SEC XBRL company facts where available, yfinance-provisional otherwise. Not a buy/sell rating, a price target, or investment advice — see the current verdict on the stock’s main page for TrendMatrix’s live read.
