How Do I Calculate A Price To Earnings Ratio?

The formula for P/E is:

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

P/E of 19.44 = NZ$4.33 ÷ NZ$0.22 (Based on the year to June 2019.)

Is A High P/E Ratio Good?

A higher P/E ratio means that investors are paying a higher price for each NZ$1 of company earnings. 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.

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. If earnings are growing quickly, then the ‘E’ in the equation will increase faster than it would otherwise. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

Spark New Zealand increased earnings per share by an impressive 12% over the last twelve months. And its annual EPS growth rate over 5 years is 4.8%. So one might expect an above average P/E ratio.

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

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. 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.

How Does Spark New Zealand’s Debt Impact Its P/E Ratio?

Spark New Zealand’s net debt is 18% of its market cap. It would probably deserve a higher P/E ratio if it was net cash, since it would have more options for growth.

The Verdict On Spark New Zealand’s P/E Ratio

Spark New Zealand trades on a P/E ratio of 19.4, which is fairly close to the NZ market average of 19.4. With only modest debt levels, and strong earnings growth, the market seems to doubt that the growth can be maintained.
