EPS — Earnings Per Share — is the foundation on which almost all equity valuation is built. The PE ratio is price divided by EPS. The PEG ratio adjusts the PE for EPS growth. Target prices are derived from projected future EPS. In short, if you want to understand stock valuation, you must first understand EPS.
But EPS is not as simple as it looks. Basic vs diluted, TTM vs annual, operating vs reported — these distinctions matter enormously when evaluating a company's true profitability.
This guide covers the EPS formula, basic vs diluted EPS, how EPS growth drives stock prices, and how companies sometimes inflate EPS without improving actual business performance.
Earnings Per Share (EPS) measures the net profit attributable to each share of common stock. It tells you how much of the company's profit "belongs" to you as a shareholder per share you own.
EPS = (Net Profit − Preferred Dividends) ÷ Weighted Average Shares Outstanding
For example, if a company earns ₹500 crore in net profit and has 10 crore shares outstanding, its EPS is ₹50 per share.
EPS is reported quarterly in India (as part of quarterly results) and annually. Most financial websites display the trailing twelve months (TTM) EPS, which is the most up-to-date figure.
Basic EPS uses only the actual shares currently outstanding — the shares that exist right now.
Diluted EPS accounts for all potential shares that could be created in the future — from employee stock options (ESOPs), convertible bonds, warrants, and other instruments. Since these potential shares would dilute existing shareholders' ownership, diluted EPS is always lower than or equal to basic EPS.
Basic EPS can be misleading when a company has large outstanding ESOPs or convertible instruments. In some fast-growing tech companies, diluted EPS can be significantly lower than basic EPS. Always compare diluted EPS figures to get the true per-share earnings picture.
The relationship between EPS and stock price is simple: Stock Price ≈ EPS × PE Ratio.
If a company's EPS grows and the PE multiple stays constant, the stock price grows by the same percentage. This is why EPS growth rate is the most important driver of long-term stock returns.
This is why experienced investors focus intensely on identifying companies that can sustain high EPS growth rates over 5–10 years. Such companies, even if they appear expensive on current PE, often deliver the best long-term returns.
Divide 72 by the annual EPS growth rate to estimate how many years it takes for EPS to double. At 20% growth, EPS doubles in ~3.6 years. At 10% growth, it takes ~7.2 years. A stock that doubles its EPS will typically at least double its price at a constant PE multiple.
The table below shows approximate EPS figures for well-known Indian companies to illustrate how EPS varies across sectors. These are illustrative figures for educational purposes only — actual values change every quarter.
| Company | Sector | Approx. EPS (₹, TTM) | Approx. 5-yr EPS CAGR | Note |
|---|---|---|---|---|
| TCS | IT Services | ~₹120–135 | ~12–15% | Consistent compounder |
| Infosys | IT Services | ~₹60–70 | ~10–13% | Strong but slower than TCS peak |
| HDFC Bank | Private Bank | ~₹75–90 | ~15–18% | Consistent 15–18% growth historically |
| Reliance Industries | Conglomerate | ~₹65–80 | ~12–16% | Jio + Retail driving growth |
| ITC | FMCG | ~₹14–16 | ~18–22% | Accelerating due to FMCG + Hotels |

Negative EPS simply means the company reported a net loss. This happens when expenses exceed revenues. But not all losses are created equal.
Strategic losses are deliberate — the company is investing heavily in growth (new stores, marketing, technology infrastructure) that will pay off later. Zomato had years of losses while building its delivery network. Amazon was loss-making for its first several years.
Structural losses indicate the core business model doesn't work — the company cannot earn more than it spends even at scale. This is fundamentally different and far more dangerous.
To distinguish them, look at unit economics: is the company profitable on a per-transaction or per-customer basis, even if not at the corporate level? If yes, scaling will eventually produce overall profits. If no, more scale just means more losses.
EPS can be inflated through several accounting and financial engineering techniques that don't reflect genuine business improvement:
When a company buys back its own shares, it reduces the total shares outstanding. If profits stay the same but shares outstanding decrease, EPS automatically increases — without any improvement in the underlying business. Many large Indian and global companies use buybacks to boost EPS figures and justify executive bonuses tied to EPS growth.
Companies sometimes record large one-time gains (selling a property, a subsidiary, or financial assets) that inflate a single year's net profit. This inflates EPS in that period but is not repeatable. Always check whether the company's "other income" line is unusually high — a common sign of one-time gains.
By recognising revenue early (before cash is actually received), companies can boost reported profits in the short term. This eventually reverses — receivables balloon, cash flow lags profit, and the manipulation becomes visible.
Compare a company's Net Profit to its Operating Cash Flow over 3–5 years. They should track each other closely. If profits are growing strongly but operating cash flow is flat or falling, something is wrong with how profits are being recognised. Cash is harder to fake than earnings.
