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 Z Energy:

P/E of 11.23 = NZ$5.28 ÷ NZ$0.47 (Based on the trailing twelve months to September 2019.)

Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio implies that investors pay a higher price for the earning power of the business. That isn't a good or a bad thing on its own, but a high P/E means that buyers have a higher opinion of the business's prospects, relative to stocks with a lower P/E.

Does Z Energy 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, Z Energy has a higher P/E than the average company (9.8) in the oil and gas industry.

That means that the market expects Z Energy will outperform other companies in its industry. Clearly the market expects growth, but it isn't guaranteed. So investors should delve deeper. I like to check if company insiders have been buying or 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. Earnings growth means that in the future the 'E' will be higher. That means unless the share price increases, the P/E will reduce in a few years. Then, a lower P/E should attract more buyers, pushing the share price up.

Z Energy's earnings per share fell by 29% in the last twelve months. But over the longer term (5 years) earnings per share have increased by 12%.

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

It's important to note that the P/E ratio considers the market capitalization, not the enterprise value. So it won't reflect the advantage of cash, or disadvantage of debt. 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.

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).

So What Does Z Energy's Balance Sheet Tell Us?

Z Energy has net debt worth 51% of its market capitalization. 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 Z Energy's P/E Ratio

Z Energy's P/E is 11.2 which is below average (18.8) in the NZ market. The P/E reflects market pessimism that probably arises from the lack of recent EPS growth, paired with significant leverage.
