When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") above 19x, you may consider Builders FirstSource, Inc. (NYSE:BLDR) as an attractive investment with its 13.6x 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 limited.

While the market has experienced earnings growth lately, Builders FirstSource's earnings have gone into reverse gear, which is not great. The P/E is probably low because investors think this poor earnings performance isn't going to get any better. If this is the case, then existing shareholders will probably struggle to get excited about the future direction of the share price.

Is There Any Growth For Builders FirstSource?

Builders FirstSource's P/E ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse 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 39% 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.

Turning to the outlook, the next year should bring diminished returns, with earnings decreasing 3.2% as estimated by the analysts watching the company. With the market predicted to deliver 15% growth , that's a disappointing outcome.

With this information, we are not surprised that Builders FirstSource is trading at a P/E lower than the market. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

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.
