How Do You Calculate A P/E Ratio?

The formula for price to earnings is:

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

Or for Post Holdings:

P/E of 62.42 = $107.30 ÷ $1.72 (Based on the year to September 2019.)

Is A High Price-to-Earnings 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. 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.

Post Holdings's P/E tells us that market participants think the company will perform better than its industry peers, going forward. The market is optimistic about the future, but that doesn't guarantee future growth. So further research is always essential. I often monitor director buying and selling.

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. When earnings grow, the 'E' increases, over time. That means unless the share price increases, the P/E will reduce in a few years. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Post Holdings shrunk earnings per share by 75% over the last year.

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. 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 Post Holdings's Balance Sheet Tell Us?

Net debt totals 85% of Post Holdings's market cap. This is a reasonably significant level of debt -- all else being equal you'd expect a much lower P/E than if it had net cash.

The Bottom Line On Post Holdings's P/E Ratio

With a P/E ratio of 62.4, Post Holdings is expected to grow earnings very strongly in the years to come. With significant debt and no EPS growth last year, shareholders are betting on an improvement in earnings from the company.
