Amazon has a market capitalization of, give or take a few billion amongst friends, $480 billion…
It has current profits of roughly $2.6 billion…
It has a price-to-earnings ratio of 184 to 1
Amazon’s shareholding passengers into the stock stratosphere may not be on a flight to quality.
Lets do the forensics on Amazon earnings present and future. Suppose we assume that ten years from now Amazon looks more like a normal company with modest growth potential, since at that point it will be thirty years old. This means it might have a price-to- earnings ratio closer to 20 to 1. This is still well above historic averages in the stock market, but we are plausibly in an era in which price-to-earnings ratios will be higher, and returns lower, than in prior decades.
Let’s assume that people expect a real return of 7.0 percent annually on their Amazon stock. This is the long-term average return in the stock market. While returns are likely to be somewhat lower going forward, it is reasonable to think that investors would expect a higher return on its stock than say GM or Walmart since Amazon is a fast-growing company and doesn’t pay a dividend.
This assumption implies that in ten years Amazon’s market capitalization will be just under $980 billion, in today’s dollars. If Amazon has a price-to-earnings ratio of 20 in 2027 then it will have after-tax profits of $49 billion in 2027. The Congressional Budget Office projects that after-tax corporate profits in 2027 will be just under $1,400 billion (in 2017 dollars), which means that Amazon will be earning an amount roughly equal to 3.5 percent of all U.S. profits in 2027.
There are three ways to get from its current profit level to the $49 billion it will need in 2027 to have a 20 to 1 PE ratio in that year. It can keep its current profit margin and have sales expand to a point where its profits are $49 billion. It can have its share of the market stay roughly constant, implying 2.0 percent annual growth, and have its profit margin increase, or it can have some combination of the two.
In the first scenario its sales will have to expand to $2.44 trillion by 2027. This is shown in Figure 1 below
This implies that in 2027, Amazon’s annual sales will be just a bit less than 10 percent of GDP. Since much of GDP involves areas like health care, rent, and education, areas in which Amazon does not currently have a presence, it would have to be an incredibly dominant actor in the segments of the market where it does operate.
The other route would imply that Amazon sales will be $166 billion in 2027. From this volume of sales it must generate almost $49 billion in profits. This would imply that its profit margins would have to rise from 2.0 percent of sales at present to more than 29.0 percent of sales in 2027. This is shown in Figure 2 below.
If Amazon were to hike its prices enough to achieve these margins it certainly would imply a very different shopping experience for its customers.
Of course, there can be some mix between these two paths, but it seems unlikely that Amazon would be able to substantially increase its market share even as it is pushing up its profit margins.
Amazon’s Profits, without Amazon Web Services
Amazon’s main source of profits in the last few years has been its web service division. While this division accounts for just 9.0 percent of the company’s revenue, it accounts for almost 75 percent of its profits. While it is possible that this division will continue to expand rapidly like the rest of the company, it is also possible that it will face serious constraints going forward.
Amazon was able to get a huge head start in this market, jumping in ahead of other tech giants like Apple, Google, and Microsoft. Now these companies are all making big pushes into this market. Let’s imagine as one possibility that competition from these companies leaves Amazon’s profits on its web service division unchanged in real terms over the next decade. This could mean that it either is forced to reduce margins substantially to maintain its share or it surrenders much of its share to its rivals, but keeps its margin in web services.
Either way, this assumption would imply that the company must generate $46.6 billion in profits from its non-web services. Excluding web services, Amazon’s current profits are equal to just 0.6 percent of sales. If the company is to generate $46.6 billion in profits in 2027 from its non-web services and keep its profit margins constant, then it will need sales of more than $7.4 trillion in 2027 (in 2017 dollars). This is shown in Figure 3 below.
In this scenario Amazon’s 2027 non-AWS revenue would be roughly equal to 30 percent of US GDP.
The other extreme case is that sales just grow 2.0 percent a year and Amazon gets its $46.6 billion in non-AWS profits by increasing its profit margin. This scenario is only slightly different than the one shown in Figure 2 above, although the profit share on non-AWS sales would now have to be 30.4 percent instead of 29.5 percent. This is shown in Figure 4.
Here we can also envision a mix of rising margins and rising sales, but it is difficult to see how this will get Amazon to $46.6 billion in profits on its non-AWS sales.
