TETRA Technologies, Inc.'s (NYSE:TTI) price-to-earnings (or "P/E") ratio of 71.1x 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 19x and even P/E's below 11x are quite common. 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.

While the market has experienced earnings growth lately, TETRA Technologies' earnings have gone into reverse gear, which is not great. It might be that many expect the dour 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.

How Is TETRA Technologies' Growth Trending?

The only time you'd be truly comfortable seeing a P/E as steep as TETRA Technologies' is when the company's growth is on track to outshine the market decidedly.

Retrospectively, the last year delivered a frustrating 75% decrease to the company's bottom line. This has erased any of its gains during the last three years, with practically no change in EPS being achieved in total. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

Turning to the outlook, the next three years should generate growth of 204% per year as estimated by the five analysts watching the company. That's shaping up to be materially higher than the 10% each year growth forecast for the broader market.

In light of this, it's understandable that TETRA Technologies' 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 Final Word

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that TETRA Technologies maintains its high P/E on the strength of its forecast growth being higher than the wider market, as expected. Right now shareholders are comfortable with the P/E as they are quite confident future earnings aren't under threat. Unless these conditions change, they will continue to provide strong support to the share price.

And what about other risks? Every company has them, and we've spotted 3 warning signs for TETRA Technologies (of which 1 can't be ignored!) you should know about.
