With a price-to-earnings (or "P/E") ratio of 54.9x Avantor, Inc. (NYSE:AVTR) 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.

With earnings that are retreating more than the market's of late, Avantor has been very sluggish. One possibility is that the P/E is high because investors think the company will turn things around completely and accelerate past most others in the market. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

What Are Growth Metrics Telling Us About The High P/E?

In order to justify its P/E ratio, Avantor would need to produce outstanding growth well in excess of the market.

Retrospectively, the last year delivered a frustrating 58% decrease to the company's bottom line. Still, the latest three year period has seen an excellent 31% overall rise in EPS, in spite of its unsatisfying short-term performance. Accordingly, while they would have preferred to keep the run going, shareholders would probably welcome the medium-term rates of earnings growth.

Turning to the outlook, the next three years should generate growth of 42% each year as estimated by the analysts watching the company. Meanwhile, the rest of the market is forecast to only expand by 10% each year, which is noticeably less attractive.

In light of this, it's understandable that Avantor's P/E sits above the majority of other companies. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.

What We Can Learn From Avantor's P/E?

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.
