Is it always accurate to add Debt to Equity Value when calculating Enterprise Value?

• A. In most cases, yes, because the debt is typically refinanced in an acquisition and the buyer pays off the seller's debt.
• B. There could be exceptions where the buyer does not pay off the debt.
• C. Debt should be ignored for EV if convertibles.
• D. Debt is only added if there is cash.

Answer: (A)

The main idea is that Enterprise Value reflects the total value of the company to all capital providers, not just equity. To capture that, you start with equity value and add the company’s outstanding obligations that a buyer would need to assume or refinance.

Debt is added to equity value because, in an acquisition, the buyer generally takes on or refinances the existing debt, so the purchase price effectively needs to cover both the equity and the debt. That’s why EV rises by the amount of debt. Cash is then subtracted to reflect that the buyer can use available cash to offset part of the cost, giving a net measure of the amount the buyer would actually pay.

There are exceptions where the debt handling is different (for example, debt that remains with the seller or is treated differently in deal financing), so it’s not literally “always” true in every structure. But in the standard valuation framework, adding debt to equity value is the usual and correct approach to reflect the full financing obligation of the business.
