### How Do You Calculate A P/E Ratio?

The formula for P/E is:

Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)

Or for MainStreet Bancshares:

P/E of 12.66 = \$21.60 ÷ \$1.71 (Based on the year to September 2019.)

### Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that investors are paying a higher price for each \$1 of company earnings. That is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.

### Does MainStreet Bancshares Have A Relatively High Or Low P/E For Its Industry?

The P/E ratio indicates whether the market has higher or lower expectations of a company. As you can see below MainStreet Bancshares has a P/E ratio that is fairly close for the average for the banks industry, which is 12.7.

MainStreet Bancshares’s P/E tells us that market participants think its prospects are roughly in line with its industry. If the company has better than average prospects, then the market might be underestimating it. I would further inform my view by checking insider buying and selling., among other things.

### How Growth Rates Impact P/E Ratios

Probably the most important factor in determining what P/E a company trades on is the earnings growth. When earnings grow, the ‘E’ increases, over time. And in that case, the P/E ratio itself will drop rather quickly. A lower P/E should indicate the stock is cheap relative to others — and that may attract buyers.

MainStreet Bancshares’s earnings made like a rocket, taking off 62% last year. The cherry on top is that the five year growth rate was an impressive 25% per year. So I’d be surprised if the P/E ratio was not above average.

### Remember: P/E Ratios Don’t Consider The Balance Sheet

It’s important to note that the P/E ratio considers the market capitalization, not the enterprise value. In other words, it does not consider any debt or cash that the company may have on the balance sheet. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.

### So What Does MainStreet Bancshares’s Balance Sheet Tell Us?

With net cash of US\$47m, MainStreet Bancshares has a very strong balance sheet, which may be important for its business. Having said that, at 27% of its market capitalization the cash hoard would contribute towards a higher P/E ratio.

### The Bottom Line On MainStreet Bancshares’s P/E Ratio

MainStreet Bancshares trades on a P/E ratio of 12.7, which is below the US market average of 18.3. Not only should the net cash position reduce risk, but the recent growth has been impressive. One might conclude that the market is a bit pessimistic, given the low P/E ratio.
