Price multiples, enterprise value and asset-based valuation
A justified forward P/E equals the payout ratio divided by (r − g), so higher growth and lower risk justify higher multiples. The method of comparables values a share at its peers' multiple (the law of one price). Enterprise value multiples such as EV/EBITDA (EBITDA is earnings before interest, taxes, depreciation, and amortization) compare companies with different debt. Asset-based valuation sums fair-valued assets minus liabilities.

Why do analysts use price multiples?
A price multiple compares a share’s price with some monetary figure per share, such as earnings, sales, cash flow or book value. It tells you how much investors pay for each unit of that figure, and so how the share compares with others. Multiples are easy to compute, widely published and good for screening a sector for relatively cheap or dear shares.
- P/E (price to earnings) Memorize the most quoted; but negative or one-off earnings distort it
- P/B (price to book value) Memorize good for banks and asset-heavy firms; ignores intangibles
- P/S (price to sales) Memorize positive even with losses and hard to manipulate; ignores costs
- P/CF (price to cash flow) Memorize less affected by accruals; cash flow definitions vary
The trailing P/E uses earnings per share for the last year or last four quarters. The forward (leading) P/E uses forecast earnings. A criticism of any trailing multiple is that it looks backward. The fix is a forward multiple, but then the forecasts are doing the work. Whichever you choose, apply it the same way to every company you compare.
The other common multiples divide the price by sales per share, by a measure of cash flow per share (operating cash flow or free cash flow), or by book value per share. Price-to-sales stays positive when earnings are negative and is harder to manipulate than earnings, but it ignores costs. Price-to-cash-flow is less affected by accounting accruals, but cash flow definitions vary. Price-to-book suits asset-heavy firms and banks, but ignores intangibles.
How does P/E relate to fundamentals?
A multiple is not arbitrary. Take the Gordon growth model with price equal to value: . Divide both sides by next year’s earnings and the dividend becomes the payout ratio . The result is the justified P/E , the multiple that fundamentals support.
Because , the trailing version is the forward version times .
A company pays out 40.00% of earnings. Its required return is 9.00% and its expected long-run growth rate is 5.00%. Its justified forward P/E is closest to:
0.4 ÷ (0.09 − 0.05) = 10
Justified forward P/E10
- 0.4÷(0.09−0.05)=10
- 0.4ENTER0.09ENTER0.05−÷10
ENTER enter (on the HP, puts the number on the stack)
The formula tells you which way each driver pushes the multiple. The P/E rises with growth and falls with the required return, so riskier companies deserve lower multiples. It also appears to rise with the payout ratio. That last link needs care, because a company that pays out more retains less and so grows more slowly (sustainable growth is ). The effects interact.
Go deeper Payout against growth
Take return on equity (ROE) = 12% and r = 9%. If the payout is 30%, growth is 0.70 × 12% = 8.4% and the forward P/E is 0.30 ÷ (0.09 − 0.084) = 50.0. At 50% payout, growth is 6.0% and the P/E is 0.50 ÷ 0.03 = 16.7. At 70%, growth is 3.6% and the P/E is 0.70 ÷ 0.054 = 13.0. Here the P/E falls as the payout rises, because the company earns more on retained money (12%) than shareholders require (9%). Retention creates value only when ROE is above r. This is the “dividend displacement of earnings”.
How does the method of comparables work?
The method of comparables is the most widely used approach to price-multiple valuation. Its logic is the law of one price : identical assets should sell for the same price. Choose a benchmark multiple (a closely matched stock, or the average or median of the industry, or the company’s own history) and multiply it by the company’s own fundamental. The difference from a justified multiple is where the expectations come from: a justified P/E is built from your own forecasts of payout, growth and risk, while a comparables multiple takes the market’s pricing of similar companies as given.
Comparable companies trade at a median multiple of 15 times a fundamental. The company's fundamental is 2.40 per share. The value per share indicated by the method of comparables is closest to:
15 × 2.40 = 36.00
Indicated value per share36.00
- 15×2.4=36
- 15ENTER2.4×36
ENTER enter (on the HP, puts the number on the stack)
Try this 0 of 3
- Justified P/E: with r at 9%, raise growth from 5% to 7%
- Comparables: give one peer a P/E of 40 or more
- EV: forget to subtract the cash
| g | 3% | 4% | 5% | 6% | 7% |
|---|---|---|---|---|---|
| P/E | 6.7 | 8 | 10 | 13.3 | 20 |
P/E rises with the payout ratio and with growth, and falls as the required return (risk) rises. In practice a higher payout leaves less to reinvest, so it also lowers g = b × ROE.
Show working
Forward P/E = (D₁ ÷ E₁) ÷ (r − g) = 0.4 ÷ (0.09 − 0.05) = 10
Trailing P/E = (D₀ ÷ E₀) × (1 + g) ÷ (r − g) = 0.4 × 1.05 ÷ 0.04 = 10.5
- 0.4÷(0.09−0.05)=forward P/E 10
- ×1.05=trailing P/E 10.5
- 0.4ENTER0.09ENTER0.05−÷forward P/E 10
- 1.05×trailing P/E 10.5
ENTER enter (on the HP, puts the number on the stack)
Three cautions follow.
- Relative, not absolute. A company at a P/E of 18 against peers at 22 is relatively undervalued. The whole peer group may be overvalued, and the share may be dear against its intrinsic value.
- Pick the peers carefully. Match on industry, size, product mix, growth and risk. The justified P/E formula tells you what to match on: payout, growth and required return. Use forward or trailing for all, and adjust for accounting differences.
- Cyclical companies have multiples that swing with the economy, because earnings swing more than sales.
What is enterprise value?
Price multiples value only the equity. Enterprise value values the whole business. It is market capitalization plus the market value of debt, preferred stock and minority interest, minus cash and short-term investments. It is often described as the cost of a takeover: the buyer takes on the debt but receives the cash.
- Market value of equity Memorize price × shares
- plus Market value of debt Memorize a buyer takes on the debt
- plus Preferred stock Memorize a senior claim
- plus Minority interest Use it subsidiary earnings consolidated but not fully owned
- minus Cash and short-term investments Memorize a buyer gets the cash; never add it
The usual enterprise multiple is EV/EBITDA . EBITDA is earnings before interest, taxes, depreciation and amortization, a rough proxy for operating cash flow. It is calculated before any payment to lenders, preferred holders or shareholders, so it pairs naturally with a value that includes all of them.
Why use it?
- It compares companies with different capital structures. Both EV and EBITDA belong to all the capital providers together, so how a company splits its funding between debt and equity does not distort the ratio.
- It can be computed when net income is negative, since EBITDA is usually still positive, so the P/E is not available.
- It is popular in Europe and for capital-heavy industries.
If debt has no market quotation, estimate its market value from bonds with similar maturity, sector and credit quality. Using the book value of debt is only a rough substitute.
A company has a market capitalization of 2,400.00, debt of 900.00, preferred stock of 0.00, minority interest of 0.00 and cash and short-term investments of 300.00. Its enterprise value is closest to:
2,400.00 + 900.00 + 0.00 + 0.00 − 300.00 = 3,000.00

An alternative to EBITDA is operating income or revenue. Negative ratios, such as a negative EV/operating income, are hard to interpret and are set aside.
What is asset-based valuation?
Asset-based valuation estimates the fair value of a company’s assets and liabilities and takes the difference. Fair value usually starts with the balance sheet’s carrying value , also called book value , and adjusts toward market value.
An analyst values a company's assets at 1,850.00 and its liabilities at 1,120.00, both at fair value. There are 50 shares outstanding. The asset-based value per share is closest to:
(1,850.00 − 1,120.00) ÷ 50 = 14.60
Value per share14.60
- 1850−1120=÷50=14.6
- 1850ENTER1120−50÷14.6
ENTER enter (on the HP, puts the number on the stack)
- Works well Use it few intangibles; mostly current or marketable assets
- Examples banks, investment holding firms, natural resource firms, private companies, liquidations
-
- Works badly Use it value sits in things the balance sheet cannot show
- Valuable intangibles software, brands, customer relationships: gives only a floor
- Specialized or hard-to-price assets fair value differs from carrying value
- Hyperinflation asset values harder to estimate
-
The approach works best for companies with few intangible assets and a high share of current or marketable assets. These are easier to value from balance sheet items. It is also frequently combined with multiplier models to value private companies, and it becomes more useful as public companies disclose more fair values.
It works badly where value lives off the balance sheet: a good reputation, synergies, a skilled owner. In those cases it gives a floor value, and a forward-looking cash flow valuation is better. Property, plant and equipment without observable market values are hard to price, and in hyperinflation asset values are hard to estimate.
Exam tip Match the model to the thing you can measure: cash flows for a stable payer, peers for a listed company with comparables, fair-valued assets for a bank, a holding company or a liquidation.
Go deeper Valuing a small private firm
Take a family printing business that owns its building and presses. An analyst gets two appraisals for the building, subtracts the loan secured on it, and values the presses at what equivalent used machines cost to buy. That gives a value for the tangible assets. The business may also have a loyal customer base and a good location, which the asset-based approach excludes. The result is therefore a floor, and the analyst would cross-check it with a multiple of earnings or revenue for similar businesses.
Go deeper Why EV multiples are common in Europe and in capital-heavy industries
In capital-heavy industries, such as telecoms and utilities, depreciation and interest are large and differ between companies according to their accounting policies and funding. EBITDA sits above both, and enterprise value includes all the funding. The ratio therefore compares operations more cleanly than the P/E. Its weakness is that EBITDA ignores the cost of replacing the assets, so it can flatter a business that needs heavy ongoing investment.
Go deeper Backing out the growth a peer multiple implies
Rearrange the justified P/E: . A peer trading at a forward P/E of 20 with a payout of 40% and a required return of 9% implies growth of 9% − 0.40/20 = 7%. If that is more than you believe the company can sustain, the multiple is expensive, and a comparable that looks cheap against it may not be a bargain.

| Driver | Effect on justified P/E |
|---|---|
| Growth g up | up |
| Required return r up (more risk) | down |
| Payout p up, growth unchanged | up |

| Trailing formula | p(1 + g) ÷ (r − g), i.e. forward × (1 + g) |
Memory hook A multiple is a compressed discounted cash flow (DCF) valuation: growth up, risk down, multiple up.
Know it cold Raising payout usually cuts growth (g = b × ROE), so the effects interact. The model needs r > g.
MemorizePrice multiples: use and flaw
| Multiple | Why use it | Flaw |

| P/CF | less affected by accruals | cash flow definitions vary |
Memory hook Each multiple fixes the previous one’s weakness: negative earnings → sales; accruals → cash flow; losses → book.
Know it cold Multiples are RELATIVE. Cheap against peers is not cheap against intrinsic value.

Exam traps
- Adding cash to enterprise value instead of subtracting it.
- Mixing a forward multiple for the peers with a trailing multiple for the target (or the reverse).
- Concluding 'undervalued' from comparables without noting that the whole peer group could be mispriced.

- Valuing a company full of intangibles by its balance sheet: the answer is only a floor.

- Justified forward P/E = payout ÷ (r − g). Trailing = forward × (1 + g).
- Comparables: peer multiple × own fundamental. Relative, not absolute.
