Earnings per share (EPS) is the amount of last year's earnings per each outstanding share of a company's stock.
NOTE: This is calculated on a Diluted Normalised basis, i.e. taking into account options and other sources of dilution and any unusual/one-time/special items in order to better reflect underlying results.
EPS is a carefully scrutinized metric that is often used as a barometer of a company's profitability. It is also used as the denominator in the P/E ratio.
