When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") below 16x, you may consider Montauk Renewables, Inc. (NASDAQ:MNTK) as a stock to avoid entirely with its 35.5x P/E ratio. 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, Montauk Renewables has been very sluggish. 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?

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

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 37%. Unfortunately, that's brought it right back to where it started three years ago with EPS growth being virtually non-existent overall during that time. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

Shifting to the future, estimates from the dual analysts covering the company suggest earnings should grow by 34% per year over the next three years. That's shaping up to be materially higher than the 10% per annum growth forecast for the broader market.

With this information, we can see why Montauk Renewables 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.

The Key Takeaway

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.

As we suspected, our examination of Montauk Renewables' analyst forecasts revealed that its superior earnings outlook is contributing to its high P/E. At this stage investors feel the potential for a deterioration in earnings isn't great enough to justify a lower P/E ratio. It's hard to see the share price falling strongly in the near future under these circumstances.
