Earnings Per Share — The Foundation of Stock Valuation

EPS is net profit divided by the number of outstanding shares. If Reliance Industries earns ₹67,000 crore in a year and has 675 crore outstanding shares, EPS is approximately ₹99. This single number is the most widely used measure of corporate profitability in per-share terms — and virtually every other valuation ratio (PE, PEG, dividend yield) rests on it.

The reason EPS matters more than raw profit is comparability. Infosys earned ₹26,248 crore in FY24 while Wipro earned ₹11,063 crore. But Wipro has more shares outstanding. EPS normalises this, letting you compare profitability per unit of ownership across companies of different sizes and capital structures.

Basic vs Diluted EPS — Why the Difference Matters

Basic EPS uses only the shares currently outstanding. Diluted EPS adds all the shares that could come into existence — from employee stock options (ESOPs), convertible bonds, warrants, and convertible preference shares. Diluted EPS is always lower than or equal to basic EPS.

For most large-cap Indian companies, the difference between basic and diluted EPS is small. But for fast-growing startups and technology companies that hand out ESOPs aggressively, dilution can be significant. Zomato, Nykaa, and Paytm — all listed post-2021 — had substantial ESOP pools. Their diluted EPS reflects a larger share count, reducing the per-share earnings figure.

Always use diluted EPS for PE ratio calculations. Using basic EPS overstates profitability per share when dilutive instruments exist, making the stock appear cheaper than it actually is.

Quarterly EPS Surprises and Stock Price Reaction

Indian markets respond sharply to quarterly earnings versus analyst estimates. A positive EPS surprise — where actual EPS exceeds the consensus estimate by 5% or more — typically drives a 3–8% stock price move in the session following results. A negative surprise of similar magnitude can drop a stock 8–15% on results day.

The July–October quarter (Q1 results, April–June period) and January–February (Q3 results) are the busiest earnings seasons. BSE lists results dates in advance, and algorithmic traders position heavily around high-impact results for Nifty 50 constituents.

Watch the reaction to earnings, not just the earnings themselves. When HDFC Bank reported strong Q3 FY24 results but the stock fell, the market was pricing in slower growth guidance — showing that EPS in isolation is never the full story. Quarterly earnings call transcripts (available on NSE and BSE filing portals) give management commentary that often moves stocks more than the numbers.

EPS Manipulation — Red Flags to Catch Early

EPS can be massaged in several ways. Watch for these in Indian company results. Share buybacks reduce the denominator (shares outstanding) without improving the business — EPS rises mechanically. Companies like Infosys and TCS do large buybacks, which is fine for mature businesses returning cash. But if a debt-laden company is buying back shares to boost EPS, that is a red flag.

One-time gains inflating EPS: A company selling a subsidiary or land parcel shows a large one-time profit. This pumps EPS for one quarter but masks the operating reality. Always check 'EPS from continuing operations' separately from total EPS in the income statement footnotes.

Aggressive revenue recognition: IT and real estate companies can sometimes book revenue early. If receivables are growing faster than revenue, revenue may be recognised before cash is collected. Compare EPS growth with cash flow from operations — if profits are growing but operating cash flow is flat, investigate.
