Today, we’ll introduce the concept of the P/E ratio for those who are learning about investing. To keep it practical, we’ll show how Tetra Tech, Inc.’s (NASDAQ:TTEK) P/E ratio could help you assess the value on offer. Tetra Tech has a price to earnings ratio of 29.84, based on the last twelve months. That means that at current prices, buyers pay $29.84 for every $1 in trailing yearly profits.
How Do You Calculate A P/E Ratio?
The formula for price to earnings is:
Price to Earnings Ratio = Share Price ÷ Earnings per Share (EPS)
Or for Tetra Tech:
P/E of 29.84 = $86.10 ÷ $2.89 (Based on the trailing twelve months to September 2019.)
Is A High P/E 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 Tetra Tech Have A Relatively High Or Low P/E For Its Industry?
One good way to get a quick read on what market participants expect of a company is to look at its P/E ratio. As you can see below, Tetra Tech has a higher P/E than the average company (26.4) in the commercial services industry.
That means that the market expects Tetra Tech will outperform other companies in its industry.
How Growth Rates Impact P/E Ratios
Earnings growth rates have a big influence on P/E ratios. 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. A lower P/E should indicate the stock is cheap relative to others — and that may attract buyers.
Tetra Tech increased earnings per share by an impressive 17% over the last twelve months. And it has bolstered its earnings per share by 11% per year over the last five years. This could arguably justify a relatively high P/E ratio. Shareholders have some reason to be optimistic, but the future is always uncertain. So further research is always essential. I often monitor director buying and selling.
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. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.
While growth expenditure doesn’t always pay off, the point is that it is a good option to have; but one that the P/E ratio ignores.
How Does Tetra Tech’s Debt Impact Its P/E Ratio?
Tetra Tech’s net debt is 3.5% of its market cap. So it doesn’t have as many options as it would with net cash, but its debt would not have much of an impact on its P/E ratio.
The Verdict On Tetra Tech’s P/E Ratio
Tetra Tech trades on a P/E ratio of 29.8, which is above its market average of 18.1. The company is not overly constrained by its modest debt levels, and its recent EPS growth very solid. Therefore, it’s not particularly surprising that it has a above average P/E ratio.
