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

The formula for P/E is:

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

Or for Spire:

P/E of 22.42 = \$77.230 ÷ \$3.445 (Based on the trailing twelve months to December 2019.)

(Note: the above calculation results may not be precise due to rounding.)

### Is A High P/E Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each \$1 the company has earned over the last year. That isn’t necessarily good or bad, but a high P/E implies relatively high expectations of what a company can achieve in the future.

### How Does Spire’s P/E Ratio Compare To Its Peers?

The P/E ratio essentially measures market expectations of a company. The image below shows that Spire has a P/E ratio that is roughly in line with the gas utilities industry average (21.8).

That indicates that the market expects Spire will perform roughly in line with other companies in 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. That’s because companies that grow earnings per share quickly will rapidly increase the ‘E’ in the equation. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Spire’s earnings per share grew by 3.7% in the last twelve months. And it has bolstered its earnings per share by 6.7% per year over the last five years.

### A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. That means it doesn’t take debt or cash into account. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on growth.

Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.

### Is Debt Impacting Spire’s P/E?

Spire’s net debt is 77% 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 Spire’s P/E Ratio

Spire trades on a P/E ratio of 22.4, which is above its market average of 13.6. With significant debt and fairly modest EPS growth last year, shareholders are betting on sustained improvement.
