Open any Indian company's quarterly result and look for earnings per share. You will find it four times, not once.
Basic and diluted, before extraordinary items and after them. Every one of the four is marked "not annualised".
One number needing four rows tells you something useful about it. The formula itself is simple, and what goes into it is not.
What Is Earnings Per Share (EPS)?
The earnings per share meaning is straightforward. It is the profit that belongs to each equity share of a company.
Take the profit for a period, and divide it by the number of shares. The result is what one share earned.
Equity shares are the ordinary shares most investors hold. Preference shares are a separate class whose dividend comes out before this sum begins.
Earnings Per Share Formula and How to Calculate EPS
Ind AS 33 is the Indian accounting standard for this. Under it, basic EPS is the profit attributable to ordinary equity holders, divided by the weighted average number of ordinary shares outstanding.
The numerator is profit after preference dividends. That part is easy.
The denominator is where care is needed. It is not the share count on the last day. It is the average across the period, weighted by how long each share was actually outstanding.
Earnings Per Share Example
A company earns ₹10 crore in a year. It begins the year with 4 crore shares and issues 2 crore more exactly halfway through.
The year-end count is 6 crore shares, which would give ₹1.67 per share.
The weighted average is different. The first 4 crore were outstanding all year, and the new 2 crore for only half of it, so the average is 5 crore. That gives ₹2 per share.
The new shares did not help earn the profit for the first six months. The weighting is what keeps them from claiming it.
Types of Earnings Per Share
The useful list is not a taxonomy but the four figures a listed Indian company reports each quarter.
Basic and diluted, each shown before extraordinary items and after them. Extraordinary items are one-off gains or losses that are not part of ordinary trading.
Reading the wrong one of the four is the commonest mistake with this number.
Basic EPS vs Diluted EPS
Basic EPS counts the shares that exist. Diluted EPS counts the shares that could exist.
A potential ordinary share is any instrument that may entitle its holder to ordinary shares. Convertible debentures and preference shares, options and warrants all qualify.
Ind AS 33 defines dilution as a reduction in EPS, or an increase in loss per share. That second half surprises people. A loss-making company with convertibles outstanding can report a diluted loss per share that is worse than its basic one.
Both figures must be presented for every period, whether the result is a profit or a loss.
Why Is Earnings Per Share Important for Investors?
It converts a company's profit into the unit an investor actually owns, which is one share.
It also tracks well over time for one company, because the same business is measured the same way each period.
What it does not do is compare two companies. A company with 5 crore shares and one with 50 crore are not describing the same thing when they each report ₹2.

What Does a High or Low EPS Mean?
On its own, less than people expect.
A high EPS can come from strong profit, a small share count, or a one-off gain above the line. A low one can come from a recent share issue that has not yet earned anything.
The figure is a starting point for a question, not the answer to one.
EPS and P/E Ratio: What Is the Difference?
EPS is an amount in rupees. The price to earnings ratio is a multiple, and EPS is the earnings in it.
Divide the share price by EPS and you have the PE ratio, so the two are not alternatives. PE Ratio and How it is Calculated takes that further.
Limitations of Earnings Per Share
It is an accounting figure, not cash, and profit and cash generated can differ substantially in the same period.
It moves when the share count moves, which means a bonus issue or a buyback changes EPS without changing the business at all.
Extraordinary items can lift or depress it in one period, which is why the reported format separates the figures before and after them.
And it says nothing about the debt sitting behind the profit, which is what the Debt to Equity Ratio measures.
Conclusion
Earnings per share is one division, and the care is all in the denominator. Ind AS 33 requires the weighted average across the period, so shares issued late in the year cannot claim earnings they were not there for.
SEBI's reporting format then gives four versions of the answer each quarter, before and after extraordinary items, basic and diluted, none annualised.
Knowing which of the four you are reading is most of the skill, and theTechnical & Fundamental Analysis Guide sets out where it fits. On its own the figure says nothing about what a share is worth.
