EV and Equity Value

Two values, two audiences

Equity value is what the company is worth to common shareholders only: diluted shares outstanding × share price for a public company. Enterprise value is the value of the core operating business to all capital providers — equity, debt, preferred stock and minority holders.

We look at both because they answer different questions. Equity value tells you what a share is worth; enterprise value lets you compare businesses regardless of how they are financed and is what an acquirer effectively pays for the operations.

The bridge

Enterprise value = equity value + debt + preferred stock + non-controlling interest − cash − non-operating assets (for example equity investments)

• Add debt and preferred stock — they are claims on the operating business from other investors.
• Add non-controlling interest — the parent consolidates 100% of a majority-owned subsidiary's EBITDA, so EV must include the minority owners' slice to stay consistent with the metric.
• Subtract cash — cash is not needed to run the core business, and an acquirer effectively gets it back.
• Subtract equity investments / associates — their income is not in consolidated EBITDA.

Worked example

Share price 20, 50 million diluted shares → equity value 1,000. Debt 400, preferred 50, NCI 30, cash 150, equity investments 30.

EV = 1,000 + 400 + 50 + 30 − 150 − 30 = 1,300.

Going the other way, a DCF that produces an EV of 1,300 implies equity value of 1,000, or 20 per share.

Capital structure and EV

If the company borrows 100 and holds it as cash, equity value does not change, debt rises by 100 and cash rises by 100, so EV is unchanged. EV changes when the operating business changes; equity value changes with both operations and financing. That is the logic interviewers are testing.

Matching multiples to the right value

Mixing them (equity value / EBITDA) is a classic red flag.

Edge cases interviewers like

1. Negative EV — possible when cash exceeds market capitalisation plus debt, often a distressed or cash-rich company the market doubts.
2. Negative equity value — not possible for market value (share price cannot go below zero), but shareholders' equity (book value) can be negative after large losses or dividend recaps.
3. Equity value vs shareholders' equity — market value versus accounting book value.
4. Market vs book — use market values where they exist (share price, trading debt prices if very different from par).

Why diluted shares matter

Equity value per share is only as good as the share count. Options, warrants, restricted stock units and convertible securities can all turn into common shares, so interview answers and models use fully diluted shares outstanding, not basic shares.

Treasury stock method (options and warrants)

1. Include only in-the-money instruments (strike price below the current share price).
2. Assume they are exercised and the company receives strike × number of options in cash.
3. Assume the company uses that cash to buy back shares at the current price.
4. Net new shares = options − buyback shares.

Worked example

100 shares outstanding at 10.00. 10 options with a strike price of 5.00.

• Exercise proceeds = 10 × 5.00 = 50
• Shares repurchased = 50 ÷ 10.00 = 5
• Net new shares = 10 − 5 = 5
• Diluted shares = 105, diluted equity value = 105 × 10.00 = 1,050

If the strike were 12.00 the options would be out of the money and ignored. RSUs have no strike price, so they are simply added in full.

Convertible bonds (if-converted method)

Compare the share price with the conversion price (par value ÷ conversion ratio). If the share price is higher, the bond is in the money: count the new shares and remove the bond from debt in the EV bridge. If not, keep it as debt.

Worked example

1 million shares at 100.00. 10 million of convertible bonds with 1,000 par and a conversion price of 50.00.

• Each bond converts into 1,000 ÷ 50 = 20 shares; there are 10,000 bonds
• New shares = 10,000 × 20 = 200,000
• Share price 100 > conversion price 50, so convert: diluted shares = 1.2 million
• Diluted equity value = 1.2 million × 100 = 120 million, and the 10 million of converts is not also counted as debt

Counting the convert as both debt and equity is the most common mistake here.

Other dilutive items

• Preferred stock that converts into common is treated like a convertible.
• Earnouts and contingent shares — include if the conditions are likely to be met.
• When a deal price rather than the market price is used (M&A), recompute dilution at the offer price, because more options are in the money.

How much dilution is too high?

There is no fixed rule, but if diluted equity value is more than roughly 10–20% above basic equity value, investors and boards focus on it, and management incentive plans come under scrutiny.

Interview checklist

• State the method (treasury stock or if-converted).
• Show the arithmetic in one line.
• Say where the item goes in the EV bridge.
• Mention that you recompute at the offer price in an acquisition.
