The AZEK Company Inc.'s (NYSE:AZEK) price-to-earnings (or "P/E") ratio of 56.3x might make it look like a strong sell right now compared to the market in the United States, where around half of the companies have P/E ratios below 16x and even P/E's below 9x are quite common. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

With its earnings growth in positive territory compared to the declining earnings of most other companies, AZEK has been doing quite well of late. The P/E is probably high because investors think the company will continue to navigate the broader market headwinds better than most. If not, then existing shareholders might be a little nervous about the viability of the share price.

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

AZEK'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 an exceptional 274% gain to the company's bottom line. Although, its longer-term performance hasn't been as strong with three-year EPS growth being relatively non-existent overall. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 15% each year over the next three years. Meanwhile, the rest of the market is forecast to only expand by 11% per annum, which is noticeably less attractive.

In light of this, it's understandable that AZEK'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.

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 AZEK maintains its high P/E on the strength of its forecast growth being higher than the wider market, as expected.
