When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") below 18x, you may consider ICF International, Inc. (NASDAQ:ICFI) as a stock to avoid entirely with its 29.2x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

ICF International certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. 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.

Is There Enough Growth For ICF International?

ICF International'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 56% gain to the company's bottom line. Pleasingly, EPS has also lifted 51% in aggregate from three years ago, thanks to the last 12 months of growth. So we can start by confirming that the company has done a great job of growing earnings over that time.

Shifting to the future, estimates from the five analysts covering the company suggest earnings should grow by 11% over the next year. That's shaping up to be materially lower than the 15% growth forecast for the broader market.

In light of this, it's alarming that ICF International's P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than analysts indicate and aren't willing to let go of their stock at any price. There's a good chance these shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the growth outlook.

The Key Takeaway

Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

Our examination of ICF International's analyst forecasts revealed that its inferior earnings outlook isn't impacting its high P/E anywhere near as much as we would have predicted. 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.
