With Smurfit Westrock Plc (NYSE:SW) It Looks Like You'll Get What You Pay For

Simply Wall St

With a price-to-earnings (or "P/E") ratio of 70.1x Smurfit Westrock Plc (NYSE:SW) 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 19x and even P/E's lower than 11x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

Smurfit Westrock could be doing better as its earnings have been going backwards lately while most other companies have been seeing positive earnings growth. One possibility is that the P/E is high because investors think this poor earnings performance will turn the corner. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Growth For Smurfit Westrock?

Smurfit Westrock'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 72% decrease to the company's bottom line. The last three years don't look nice either as the company has shrunk EPS by 82% in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Turning to the outlook, the next three years should generate growth of 85% per annum as estimated by the analysts watching the company. That's shaping up to be materially higher than the 11% each year growth forecast for the broader market.

With this information, we can see why Smurfit Westrock is trading at such a high P/E compared to the market. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.
