Capital structure describes how a company funds itself: how much comes from equity (owners) and how much from debt (borrowers). Two companies can run similar operations but choose very different mixes.
Market cap alone penalises companies that use debt, because debt sits outside the equity value. Enterprise value deliberately includes debt, so it lets you compare the operating businesses more fairly.
| Company (fictional) | Market cap | Debt | Cash | Enterprise value |
|---|---|---|---|---|
| Deccan Motors Ltd | ₹4,000 Cr | ₹1,500 Cr | ₹200 Cr | ₹5,300 Cr |
| Pinnacle Paints Ltd | ₹5,200 Cr | ₹100 Cr | ₹900 Cr | ₹4,400 Cr |
The company with the smaller market cap can have the larger enterprise value once debt is included.
If you wanted to compare how expensive these two businesses are, you would normally look at enterprise value rather than market cap, because EV reflects the cost of the whole business regardless of how it is financed.
Enterprise value ≈ Market cap + Total debt − Cash
