Potbelly Corporation's (NASDAQ:PBPB) Prospects Need A Boost To Lift Shares

When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") above 18x, you may consider Potbelly Corporation (NASDAQ:PBPB) as a highly attractive investment with its 6x P/E ratio. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

With its earnings growth in positive territory compared to the declining earnings of most other companies, Potbelly has been doing quite well of late. It might be that many expect the strong earnings performance to degrade substantially, possibly more than the market, which has repressed the P/E. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

Does Growth Match The Low P/E?

Potbelly's P/E ratio would be typical for a company that's expected to deliver very poor growth or even falling earnings, and importantly, perform much worse than the market.

If we review the last year of earnings growth, the company posted a terrific increase of 190%. Still, EPS has barely risen at all from three years ago in total, which is not ideal. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

Shifting to the future, estimates from the four analysts covering the company suggest earnings growth is heading into negative territory, declining 40% over the next year. Meanwhile, the broader market is forecast to expand by 15%, which paints a poor picture.

In light of this, it's understandable that Potbelly's P/E would sit below the majority of other companies. However, shrinking earnings are unlikely to lead to a stable P/E over the longer term. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

What We Can Learn From Potbelly's P/E?

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 Potbelly maintains its low P/E on the weakness of its forecast for sliding earnings, as expected. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. It's hard to see the share price rising strongly in the near future under these circumstances.

Having said that, be aware Potbelly is showing 3 warning signs in our investment analysis, and 1 of those is significant.
