TO GET ITWhat EPS is, the heartbeat of a listed company
Earnings per share: a company's profit split across each share. The number everyone cites and few actually calculate.
WHAT IT MEASURES
profit
per single share
FORMULA
÷ shares
profit over share count
WHAT FOR
the P/E
price divided by EPS
THE RULE
÷
↑ net profit divided by the number of shares
EPS takes a company's annual net profit and divides it by all its shares. That tells you how much the company earns for each share you own, no matter how big or small the company is.
EXAMPLE
SIMPLE RULE$10
$10
= $100M profit ÷ 10M shares
The number is just a division. What's powerful is what it tells you: how much profit backs each share you hold.
If a company earns 100 million and has 10 million shares, each share 'earns' 10. That's its EPS.
- DIVISION
- — Total profit split across all existing shares.
- BACKING
- — The real profit that supports each share's price.
KEY IDEA
AUTHORITYPrice guesses, EPS confirms
“A stock can rise on enthusiasm, but only earnings per share tells you whether that enthusiasm is backed by real profit.”
A share price is an opinion; EPS is an accounting fact. Comparing the two is exactly what the P/E does.
- OPINION
- — The price reflects what the market believes, not always what the company earns.
- ACCOUNTING FACT
- — A figure that comes from the company's audited accounts.
- P/E
- — How many years of EPS you pay when you buy the share.
HOW TO READ IT
EXAMPLEAn EPS that grows year after year
What matters isn't one year's EPS, it's its trend. Growing steadily is worth more than a single strong print.
Illustrative curve, not real data. A steadily rising EPS is the sign of a company earning more per share each year.
- ILLUSTRATIVE
- — An example chart to explain the idea, not real figures.
- TREND
- — The sustained direction of a figure over several years.
WHY IT MATTERS
THREE KEYSThree things EPS teaches you
IT FEEDS THE P/E
The P/E is price divided by EPS. If EPS rises and the price doesn't, the stock gets cheaper without you doing anything.
BUYBACKS LIFT IT
If the company buys back shares, the same profit is split across fewer shares: EPS rises even if the company earns no more.
DILUTION LOWERS IT
If it issues new shares (to pay for acquisitions or reward staff), profit is split across more shares and EPS falls.
EPS isn't just a figure: it explains the P/E, buybacks and dilution at a glance.
- BUYBACK
- — The company buys its own shares and retires them.
- DILUTION
- — Issuing new shares cuts the slice that goes to each one.
- P/E
- — Price divided by EPS: how many years of profit you pay.
WHERE IT COMES FROM
EXAMPLEHow a dollar of revenue is split
Of every dollar that comes in, only a slice ends up as profit. That slice, divided by the shares, is EPS.
A typical, illustrative split. Only the last slice, net profit, is what becomes EPS.
- REINVESTMENT
- — Money the company spends to grow instead of paying out.
- NET PROFIT
- — What's left after all costs and taxes.
EXAMPLES
TO SEE ITFour cases that show how EPS behaves
| SPY | ~750 | → +0.0% | The index: its aggregate EPS is the 'market's profit' everyone watches. |
| AAPL | ~230 | → +0.0% | Aggressive buybacks: lifts EPS by shrinking the share count. |
| KO | ~70 | → +0.0% | Stable, growing EPS: the base of a dividend that holds for years. |
| ARKK | ~60 | → +0.0% | Companies reinvesting everything: low or negative EPS, valued on the future. |
Rounded prices, no figure from today. Each name illustrates a different way EPS behaves.
- ETF
- — A listed basket that tracks an index or theme.
- AGGREGATE
- — The sum of EPS across all companies in the index.
- DIVIDEND
- — The part of profit a company pays out per share.
