Enterprise Value vs Market Cap: How Debt Changes Share Value

Two businesses each generate 200 million in annual EBITDA. One has a market capitalization of 800 million; the other is valued by the stock market at 1,100 million. The first looks cheaper—until its larger debt burden enters the calculation. With the assumptions below, both have an enterprise value of 1,200 million and trade at six times EBITDA.

The distinction matters because buying a share buys a residual claim, not the entire business free of its financing obligations. Enterprise value can help compare operating businesses. Only the value attributable to ordinary shareholders can be divided by ordinary shares to obtain a consistent per-share estimate.

Reconstruct what the market price includes

Start with an intentionally simple, hypothetical nonfinancial company. All amounts are millions of one currency unless stated per share. Company A has 100 million ordinary shares priced at 8, debt valued at 500 and 100 of cash eligible for the chosen cash adjustment. There are no preferred shares, noncontrolling interests, leases or convertibles in this base case.

Market capitalization is 100 × 8 = 800. Enterprise value, abbreviated EV, is 800 + 500 − 100 = 1,200. Net debt is 400. Reading the bridge in reverse gives ordinary-equity value of 1,200 − 400 = 800, or 8 per share. Cash is subtracted when moving from equity to operating EV and added when moving back; reversing that sign is a common error.

Company B has the same 100 million shares, a price of 11, debt of 200 and eligible cash of 100. Its market cap is 1,100, yet EV is also 1,200. Dividing each EV by EBITDA of 200 gives 6 times. Dividing market cap by EBITDA would instead give 4 and 5.5 times: those ratios mix an equity-only numerator with earnings before financing costs and do not measure the same operating valuation.

This does not establish that A and B are equally attractive. Growth, margins, capital expenditure, cash conversion and refinancing exposure can differ. Matching the numerator and denominator removes one misleading comparison; it does not complete the valuation.

A 10% fall in business value can mean a 15% fall for equity

Now use A as a valuation sensitivity, not a forecast. Hold debt and cash fixed while the assumed value of its operations falls from 1,200 to 1,080. Equity falls from 800 to 680, or from 8 to 6.80 per share. The operating-value decline is 10%; the equity decline is 15%.

With fixed net debt, the percentage sensitivity is EV divided by equity: 1,200/800 = 1.5. The third row adds a different assumption. If only 50 of cash remains and the remaining operations are still worth 1,080, equity is 630, 21.25% below the starting value. A cash outflow is not automatically value destruction: equipment or an acquisition may add operating value. The example holds that value fixed explicitly. Do not deduct the same past cash burn again from a valuation of future cash flows.

Nor is 1.5 a permanent leverage coefficient. New equity, dividends, acquisitions, debt repricing and changes in liquidity can move both sides of the bridge. A distressed company particularly needs a fresh assessment of creditor claims and priority. A negative result from a crude subtraction is not a tradable negative share price; it is a warning that the simple valuation framework is inadequate.

Paying down debt does not automatically create equity value

Return to the starting case. Suppose A uses its 100 of cash to repay 100 of debt at par, with no fee, tax effect or change in operating value. Debt becomes 400 and cash becomes zero. Net debt remains 400; the same EV of 1,200 still leaves equity of 800.

Gross debt is lower, but the cash asset has fallen by the same amount. Adding 100 to the equity estimate just because debt was repaid counts the improvement twice. Repayment can still affect future interest costs, refinancing exposure or the appropriate discount rate. Those effects need explicit valuation assumptions; they are not a free gain produced by rearranging the bridge.

The simple bridge must expand when other claims exist

Consider a separate, more complete case: operating EV of 1,200, eligible cash of 100, a separately valued nonconsolidated investment of 80, debt of 500, preferred equity of 40 and noncontrolling interests valued at 60. Ordinary-equity value is 1,200 + 100 + 80 − 500 − 40 − 60 = 780. With 100 million ordinary shares, that is 7.80 per share—not 12.

The 60 adjustment matters when the operating valuation includes 100% of a consolidated subsidiary but some of that subsidiary belongs to outside shareholders. Subtract their claim once. Do not first reduce all consolidated operating value by an ownership percentage and then subtract the same outside interest again. Conversely, add the 80 investment only if it was not already valued in the operating cash flows or denominator.

Use claims and assets measured at a consistent date and on an appropriate value basis. Balance-sheet debt is sometimes used as a proxy, but it can differ materially from market value. The debt amount an acquirer must settle can also differ from the market value used in a trading multiple. A transaction price and a stock-screening EV need not be interchangeable.

Cash, leases and EBITDA can change the apparent bargain

Check the cash footnotes before subtracting every reported balance. Restricted funds, pledged deposits and cash needed for operations may not provide the same offset as freely available surplus cash. They are not necessarily worthless; availability and economic value require separate assessment. State the convention rather than silently changing it.

For example, if 40 of A’s reported 100 is excluded from an explicitly adjusted cash offset, eligible cash is 60. That adjusted EV becomes 800 + 500 − 60 = 1,240, or 6.20 times EBITDA instead of 6.00. Do not both exclude operating cash from the offset and charge for the same requirement a second time in the business valuation.

Lease treatment also has to match. Recognized lease liabilities can be economically important; the profit measure may already reflect rent through depreciation and interest rather than a comparable operating expense. Check whether the selected EV and EBITDA series include leases consistently across companies and periods. Omitting lease debt while retaining a lease-related uplift to EBITDA can flatter the multiple.

Finally, EBITDA is not cash available to shareholders. Replacement investment, working capital, tax and financing costs still matter. Six times EBITDA is not a six-year guaranteed payback. The separate task of checking the earnings denominator in a P/E ratio helps explain why a change in the accounting base can move a multiple without changing the share price.

Build a bridge you can update after the next announcement

1. Fix the perimeter: specify operating EV, ordinary equity and the consolidated businesses included. Keep nonoperating holdings separate.
2. Align the dates: reconcile current market cap with the latest debt and cash disclosure, then incorporate intervening dividends, borrowings, buybacks and completed deals.
3. Match the earnings: compare the same historical or forecast window, lease basis and consolidation scope. Check cash conversion as well as the multiple.
4. Account for every claim once: list debt, preference capital, outside interests and dilutive securities. A convertible cannot be treated simultaneously as fully outstanding debt and fully converted equity without corresponding adjustments.
5. Recalculate per share: use a share count consistent with the equity value and dilution treatment. The weighted-average shares used for reported EPS are not automatically the right current valuation denominator.

A useful conclusion therefore states both the operating valuation and what is left for ordinary shareholders. “Six times EBITDA, with 400 of net debt and 8 per share in this scenario” is auditable. “The market cap is smaller, so the business is cheaper” is not.
