The Acquirer's Multiple: Tobias Carlisle's Take on Deep Value
Why the Acquirer's Multiple — enterprise value to operating earnings — outperforms book value and P/E as a buying signal.
Tobias Carlisle's Acquirer's Multiple — enterprise value divided by operating earnings — is the metric that a private equity buyer or corporate acquirer actually uses when evaluating whether to buy a business. It's more powerful than P/E as a value signal, and the research behind it is compelling.
Why Enterprise Value, Not Market Cap
Market cap is what you pay for the equity. Enterprise value is what you pay for the whole business — equity plus debt, minus cash. A company with £100m market cap and £50m of net debt costs you £150m to acquire fully. Dividing by operating earnings (EBIT, not EPS) gives you the actual multiple you're paying for the business's earnings power before financial engineering.
| EV / EBIT | Interpretation | Historical Alpha |
|---|---|---|
| Below 8× | Deep value — potential distress or gem | +8.2%/yr |
| 8–12× | Attractive — worth closer analysis | +4.1%/yr |
| 12–18× | Fair value — limited margin of safety | +0.8%/yr |
| Above 18× | Expensive — requires growth to justify | -2.3%/yr |
Carlisle's Research: The Numbers
In his book "Deep Value," Carlisle showed that the cheapest decile of stocks by EV/EBIT produced 17.6% annual returns from 1965–2011, vs 11.2% for the S&P 500. The key insight: this outperformance was strongest precisely when stocks in the cheapest decile looked most distressed — meaning investors with the stomach to hold when things look worst are disproportionately rewarded.
