What it is
Earnings per share (EPS) is a widely used financial metric that calculates how much profit a company generates for each outstanding share of its common stock. It is derived by dividing a company's net income, after subtracting preferred dividends, by the total number of common shares outstanding. A higher EPS generally indicates greater profitability, making it a key indicator for investors assessing a company's financial health and value.
Investors closely watch EPS figures released during earnings season, comparing them against analyst consensus estimates. A company "beating" EPS estimates can lead to a stock price increase, while a "miss" can cause a decline. EPS is also a component in valuation ratios like the price-to-earnings (P/E) ratio. Companies often use share buybacks to reduce the number of outstanding shares, which can artificially boost EPS even if net income remains constant.
Why it matters
EPS is a primary measure of a company's profitability and a key driver of stock prices. It helps you assess a company's financial health and valuation.
