This article is for investors who would like to improve their understanding of price to earnings ratios (P/E ratios). We’ll show how you can use Black Hills Corporation’s (NYSE:BKH) P/E ratio to inform your assessment of the investment opportunity. Based on the last twelve months, Black Hills’s P/E ratio is 19.1. That is equivalent to an earnings yield of about 5.2%.

### 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 Black Hills:

P/E of 19.1 = \$79.63 ÷ \$4.17 (Based on the year to March 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. All else being equal, it’s better to pay a low price — but as Warren Buffett said, ‘It’s far better to buy a wonderful company at a fair price than a fair company at a wonderful price.’

### How Growth Rates Impact P/E Ratios

Generally speaking the rate of earnings growth has a profound impact on a company’s P/E multiple. If earnings are growing quickly, then the ‘E’ in the equation will increase faster than it would otherwise. And in that case, the P/E ratio itself will drop rather quickly. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Black Hills saw earnings per share decrease by 12% last year. But over the longer term (5 years) earnings per share have increased by 8.3%.

### Does Black Hills 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. The image below shows that Black Hills has a P/E ratio that is roughly in line with the integrated utilities industry average (20.4).

Black Hills’s P/E tells us that market participants think its prospects are roughly in line with its industry. The company could surprise by performing better than average, in the future. Checking factors such as the tenure of the board and management could help you form your own view on if that will happen.

### Don’t Forget: The P/E Does Not Account For Debt or Bank Deposits

The ‘Price’ in P/E reflects the market capitalization of the company. Thus, the metric does not reflect cash or debt held by the company. Theoretically, a business can improve its earnings (and produce a lower P/E in the future) by investing in growth. That means taking on debt (or spending its cash).

Spending on growth might be good or bad a few years later, but the point is that the P/E ratio does not account for the option (or lack thereof).

### Black Hills’s Balance Sheet

Black Hills’s net debt is 65% of its market cap. This is enough debt that you’d have to make some adjustments before using the P/E ratio to compare it to a company with net cash.

### The Verdict On Black Hills’s P/E Ratio

Black Hills trades on a P/E ratio of 19.1, which is fairly close to the US market average of 17.9. With relatively high debt, and no earnings per share growth over twelve months, the P/E suggests that many have an expectation that company will find some growth.
