With a price-to-earnings (or "P/E") ratio of 26.5x Restaurant Brands International Inc. (NYSE:QSR) may be sending very bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 16x and even P/E's lower than 9x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

Restaurant Brands International hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. It might be that many expect the dour earnings performance to recover substantially, which has kept the P/E from collapsing. If not, then existing shareholders may be extremely nervous about the viability of the share price.

Does Growth Match The High P/E?

Restaurant Brands International's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

Retrospectively, the last year delivered a frustrating 4.9% decrease to the company's bottom line. However, a few very strong years before that means that it was still able to grow EPS by an impressive 57% in total over the last three years. So we can start by confirming that the company has generally done a very good job of growing earnings over that time, even though it had some hiccups along the way.

Turning to the outlook, the next three years should generate growth of 12% per annum as estimated by the analysts watching the company. That's shaping up to be similar to the 13% per year growth forecast for the broader market.

With this information, we find it interesting that Restaurant Brands International is trading at a high P/E compared to the market. It seems most investors are ignoring the fairly average growth expectations and are willing to pay up for exposure to the stock. These shareholders may be setting themselves up for disappointment if the P/E falls to levels more in line with the growth outlook.

The Key Takeaway

Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

We've established that Restaurant Brands International currently trades on a higher than expected P/E since its forecast growth is only in line with the wider market. When we see an average earnings outlook with market-like growth, we suspect the share price is at risk of declining, sending the high P/E lower. Unless these conditions improve, it's challenging to accept these prices as being reasonable.
