Earnings per share, or EPS, is a company’s net profit divided by its number of shares outstanding. It converts total profit into a per-share figure, so you can compare profitability across companies of different sizes and track it over time. EPS is the engine under the P/E ratio and the number most analyst forecasts and earnings surprises are built around.
Worked example
A company earns $500 million in net profit with 250 million shares outstanding, giving EPS of $2.00. If it buys back 50 million shares, the same profit is split across 200 million shares, lifting EPS to $2.50 with no change in the underlying business. That is why buybacks flatter EPS, and why you read it alongside revenue, not in isolation.
Diluted versus basic EPS
Basic EPS uses current shares; diluted EPS also counts options, warrants, and convertibles that could become shares, giving a more conservative figure. Always compare companies on the same basis. On Volity you act on EPS-driven moves by holding the share for the long term or trading the name as a CFD around earnings releases, where a beat or miss versus forecast EPS often moves the price hard.
Why it matters
EPS is the cleanest single read on per-share profitability and the anchor for valuation, but it is easy to massage with buybacks and one-off items. Track the trend over several years, prefer diluted, and pair it with cash flow. Related: total return and dividend.
