What is earnings per share (EPS)?
EPS is a company's net profit divided by its number of shares, showing how much profit is attributable to each share.
Earnings per share (EPS) is one of the most widely used measures of company profitability. It tells you how much of a company's net profit is attributable to each individual share. The basic formula is:
EPS = net profit (after tax) ÷ number of shares outstanding.
If a company earns Rs 5 billion in net profit and has 500 million shares, its EPS is Rs 10. In other words, each share "earned" Rs 10 of profit during that period. EPS is usually reported for the full year and quarterly, so investors can track the trend.
EPS matters because it puts profit in per-share terms, which is exactly what a shareholder owns. A company's total profit might be large, but if it has issued a huge number of shares, the profit per share — and therefore the value backing each share — is diluted. EPS cuts through company size to show profitability on the unit you actually hold.
Investors use EPS in several ways:
- Tracking growth. Rising EPS over years signals a company growing its profits on a per-share basis, which tends to support a higher share price over time. Falling EPS is a warning. - Valuation. EPS is the building block of the price-to-earnings (P/E) ratio — share price divided by EPS — the most common yardstick for whether a stock looks cheap or expensive. - Dividend context. Comparing EPS with the dividend per share gives the payout ratio, showing how much of each share's earnings is paid out versus retained.
A few cautions help you use EPS well:
- One-off items can distort it. A single large gain or loss — selling an asset, a tax adjustment, an impairment — can inflate or depress EPS in a way that does not reflect the underlying business. Analysts often look at "normalised" or recurring EPS to strip these out. - Share count changes. Bonus issues, rights issues, and splits change the share count, so EPS must be compared on a like-for-like basis; historical EPS is usually restated for such actions. - Profit can be managed. Accounting choices can shift reported earnings, so EPS is best read alongside cash flow and the broader financial statements.
For PSX investors, EPS is often the first number checked when results are announced, and the market's reaction frequently hinges on whether EPS beat or missed expectations. Read in context and over time, it is a reliable starting point for judging how profitable a company really is.
