With an average analyst rating of buy, American Tower is clearly an analyst favorite. But the analysts could be wrong. Is AMT overvalued at today's price of $178.13? Let's take a closer look at the fundamentals to find out.
American Tower has a P/E ratio of 87.3 based on its 12 month trailing earnings per share of $2.04. Considering its future earnings estimates of $4.82 per share, the stock's forward P/E ratio is 37.0. In comparison, the average P/E ratio of the Real Estate sector is 24.81 and the average P/E ratio of the S&P 500 is 15.97.
American Tower's P/E ratio tells us how much investors are willing to pay for each dollar of the company's earnings. The problem with this metric is that it doesn't take into account the expected growth in earnings of the stock. Sometimes elevated P/E ratios can be justified by equally elevated growth expectations.
We can solve this inconsistency by dividing the company's trailing P/E ratio by its five year earnings growth estimate, which in this case gives us a 4.06 Price to Earnings Growth (PEG) ratio. Since the PEG ratio is greater than 1, the company's lofty valuation is not justified by its growth levels.
We can also compare the ratio of American Tower's market price to its book value, which gives us the price to book, or P/B ratio. A company's book value refers to its present equity value -- or what is left over when we subtract its liabilities from its assets. AMT has a P/B ratio of 16.07, with any figure close to or below one indicating a potentially undervalued company.
A comparison of the share price versus company earnings and book value should be balanced by an analysis of the company's ability to pay its liabilities. One popular metric is the Quick Ratio, or Acid Test, which is the company's current assets minus its inventory and prepaid expenses divided by its current liabilities. American Tower's quick ratio is 0.446. Generally speaking, a quick ratio above 1 signifies that the company is able to meet its liabilities.
The final element of our analysis will touch on American Tower's ability to generate cash for the benefit of its shareholders or for reinvesting in the business. For this, we look at the company's levered free cash flow, which is the sum of all incoming and outgoing cash flows, including the servicing of current debt and liabilities. American Tower has a free cash flow of $5.57 Billion, which it uses to pay its shareholders a 3.5% dividend.
With most indicators pointing at a higher than average valuation with uncertain growth prospects, most analysts are either wrong about American Tower, or their research has uncovered one or more qualitative reasons to invest in the stock. For example, the strength of the management team and their plan for executing the business strategy may have convinced some analysts to give less weight to traditional quantitative factors.
