Simple definition
Earnings per share, or EPS, is a company's yearly profit divided by the number of shares it has outstanding. It shows how much profit is attached to each single share you own. Picture a pizza sliced into equal pieces: EPS is how much profit sits on each slice, no matter how many slices there are.
Why it matters
EPS is one of the most watched signals of how profitable a company is per share, and it feeds directly into the P/E ratio. Rising EPS over time can point to a healthier business, while falling EPS may be a warning worth investigating.
Real-life example
Suppose a company earns $10 million in profit for the year and has 5 million shares outstanding. Its EPS is 10 million ÷ 5 million, or $2 per share. If profit grew to $12 million with the same share count, EPS would rise to $2.40.
Formula
EPS = net income ÷ shares outstanding
Common mistakes
- Comparing raw EPS between two companies without accounting for their different share counts.
- Ignoring one-time gains or losses that can make a single year's EPS misleading.
- Forgetting that companies can lift EPS by buying back shares rather than growing profit.
- Treating rising EPS as proof of a good investment without checking the price you'd pay.
Pro tips
- Track EPS over several years to see the trend, not just one figure.
- Note whether a figure is basic or diluted EPS, which counts extra potential shares.
- Ask whether EPS growth came from real profit or from share buybacks.
- Pair EPS with the share price, since EPS alone says nothing about value.

Frequently asked questions
What's the difference between basic and diluted EPS?
Basic EPS divides profit by the shares currently outstanding. Diluted EPS also counts shares that could be created later, such as from stock options or convertible bonds. Diluted EPS is usually a bit lower and more conservative, since it assumes those extra shares exist and spread the same profit thinner.
Can a company increase EPS without earning more?
Yes. Because EPS divides profit by share count, a company can raise it by buying back its own shares, which shrinks the denominator. Profit stays flat but each remaining share represents a larger slice. That's why it helps to check whether rising EPS came from real growth or from buybacks.
Does a higher EPS mean a better stock?
Not by itself. A higher EPS means more profit per share, but it says nothing about the price you'd pay for that profit. A stock with high EPS can still be expensive. That's why EPS is usually read alongside the share price, as it is in the P/E ratio.
Knowing what Earnings Per Share means is knowledge — the first half. A brick gets placed when you act on it: find the EPS of one company you follow and check whether it has risen or fallen over the last few years.
