Extra Space Storage, Inc (NYSE: EXR) shares currently trade at 26.8x trailing earnings which is lower than the Real Estate sector median of 31.9x. While this makes EXR look like a stock to add to your portfolio, equity investors might change their mind after taking a closer look at the assumptions behind the P/E ratio. In this article, I define how to calculate a P/E multiple and what to keep an eye out for when applying it in a comparable companies analysis.
Extra Space Storage Comparable Companies Analysis
A comparable companies analysis, also known as a multiples valuation, determines the value of a subject company by benchmarking its financial performance against similar public companies or peers. We can conclude if a company looks undervalued or overvalued relative to its peers by comparing metrics like growth, profit margin, and valuation ratios.
A P/E Ratio is a valuation metric that indicates the multiple of earnings investors are willing to pay for one share of a company:
P/E Ratio = Stock Price ÷ Earnings Per Share
The P/E ratio by itself is not very helpful at all. It is only useful when comparing it to other companies that are considered similar to the subject company. The basic idea is that companies with similar characteristics should trade at similar multiples, all other things being equal. Therefore, we can come to a conclusion about the stock if the ratios are different. In the chart below, I compare Extra Space Storage’s P/E ratio to its peer group that includes Public Storage (NYSE: PSA), CubeSmart (NYSE: CUBE), Life Storage, Inc. (NYSE: LSI) and National Storage Affiliates (NYSE: NSA).
Since Extra Space Storage’s P/E of 26.8x is lower than the median of its peers (40.2x), it means that investors are paying less than they should for each dollar of EXR’s earnings. As such, our analysis shows that EXR represents an undervalued stock. In fact, finbox.io’s P/E Multiple Model calculates a fair value of roughly $121.50 per share which implies around 23.0% upside.
I selected a fair multiple of 33.0x in my analysis by averaging Extra Space Storage’s current P/E ratio with its peer group.
Are Peers Really Comparable?
Before concluding that Extra Space Storage should be added to your portfolio, it is important to understand that our conclusion rests on two important assumptions.
(1) the selected peer group actually contains companies that truly are similar to Extra Space Storage, and
(2) the selected peer group stocks are being fairly valued by the market.
If the first assumption is not accurate, the difference in P/E ratios could be due to a variety of factors. For example, if you accidentally compare Extra Space Storage with higher growth companies, then its P/E multiple would naturally be lower than its peers since investors reward high growth stocks with a higher price.

However, if the second assumption does not hold true, Extra Space Storage’s lower multiple may be because firms in our peer group are being overvalued by the market.
How This Impacts Shareholders
As a shareholder, you may have already conducted fundamental analysis on the stock so its current undervaluation could signal a potential buying opportunity to increase your position in EXR. However, keep in mind the limitations of the P/E ratio when making investment decisions. There are a variety of other fundamental factors that I have not taken into consideration in this article.
