Earnings Per Share — a company's net profit divided by its shares outstanding, the denominator in the P/E ratio and a key measure of corporate profitability.
EPS translates a company's total net income into a per-share figure, making it easy to compare profitability across companies of different sizes and to track a single company's earnings trend over time. "Basic EPS" divides net income by shares outstanding; "diluted EPS" also counts potential shares from stock options, convertible bonds, and warrants — diluted EPS is generally the more conservative and more widely used figure.
EPS growth is the engine of long-term stock price appreciation. Companies that consistently grow earnings per share at above-average rates tend to command premium valuations and deliver strong long-term returns. EPS can grow through revenue growth, margin expansion, or share buybacks (which reduce the denominator even if net income is flat) — investors scrutinize which mechanism is driving growth.
Quarterly earnings reports center on whether a company met, beat, or missed analyst EPS estimates. "Beating by a penny" often triggers a positive reaction while "missing by a penny" can cause sharp selloffs, even when the absolute dollar differences are tiny — markets are priced on expectations, and deviations from those expectations drive price action far more than absolute EPS levels.
