You would get a fairly good guide to the value of Johnson & Johnson if you looked at the
price-to-book ratios for the comparables, but the wide range of P/E ratios would give you a
hint that these ratios can be a treacherous benchmark in the pharmaceutical industry. You
would certainly want to discard outliers, such as Astra Zeneca’s P/E ratio.
The ratios for Devon Energy illustrate the potential difficulties with valuation by compa-
rables. The P/E ratios vary between 3.1 for Encana to 21.5 for Chesapeake Energy. Anadarko,
which was making a loss in 2014, did not even have a P/E ratio.
Such difficulties do not invalidate the use of comparables to value businesses. Maybe
Table 4.1 doesn’t show the most closely comparable companies. A financial manager or ana-
lyst would need to dig deeper to understand Devon’s industry and its competitors. Also the
method might work better with different ratios.^6 For example, P/E ratios are almost useless
as a guide to the value of new start-up companies, most of which do not have any earnings to
compare.
(^6) Financial analysts often use ratios of EBIT (earnings before interest and taxes) or EBITDA (earnings before interest, taxes, deprecia-
tion, and amortization) to enterprise value (the sum of outstanding debt and the market cap of equity). EBIT or EBITDA ratios are less
sensitive than P/EPS ratios to differences in financing. In Chapter 19 we cover valuation when financing comes from a mix of debt
and equity. We discuss other ratios in Chapter 28.
