Subdued Growth No Barrier To A10 Networks, Inc.'s (NYSE:ATEN) Price

A10 Networks, Inc.'s (NYSE:ATEN) price-to-earnings (or "P/E") ratio of 24.2x might make it look like a 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. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

Recent times haven't been advantageous for A10 Networks as its earnings have been falling quicker than most other companies. It might be that many expect the dismal earnings performance to recover substantially, which has kept the P/E from collapsing. 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?

A10 Networks' P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 13%. However, a few very strong years before that means that it was still able to grow EPS by an impressive 134% in total over the last three years. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been more than adequate for the company.

Shifting to the future, estimates from the four analysts covering the company suggest earnings should grow by 0.3% over the next year. That's shaping up to be materially lower than the 11% growth forecast for the broader market.

In light of this, it's alarming that A10 Networks' P/E sits above the majority of other companies. It seems most investors are hoping for a turnaround in the company's business prospects, but the analyst cohort is not so confident this will happen. Only the boldest would assume these prices are sustainable as this level of earnings growth is likely to weigh heavily on the share price eventually.

The Final Word

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 A10 Networks currently trades on a much higher than expected P/E since its forecast growth is lower than the wider market. Right now we are increasingly uncomfortable with the high P/E as the predicted future earnings aren't likely to support such positive sentiment for long. Unless these conditions improve markedly, it's very challenging to accept these prices as being reasonable.
