# Is Macmahon Holdings Limited's (ASX:MAH) P/E Ratio Really That Good?

The goal of this article is to teach you how to use price to earnings ratios (P/E ratios). We'll look at Macmahon Holdings Limited's (ASX:MAH) P/E ratio and reflect on what it tells us about the company's share price. Macmahon Holdings has a P/E ratio of 10.04, based on the last twelve months. That is equivalent to an earnings yield of about 10.0%.

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

The formula for price to earnings is:

Price to Earnings Ratio = Price per Share Ã· Earnings per Share (EPS)

Or for Macmahon Holdings:

P/E of 10.04 = A\$0.22 Ã· A\$0.022 (Based on the year to June 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 necessarily good or bad, but a high P/E implies relatively high expectations of what a company can achieve in the future.

### Does Macmahon Holdings 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. We can see in the image below that the average P/E (11.9) for companies in the metals and mining industry is higher than Macmahon Holdings's P/E.

Its relatively low P/E ratio indicates that Macmahon Holdings shareholders think it will struggle to do as well as other companies in its industry classification. While current expectations are low, the stock could be undervalued if the situation is better than the market assumes. If you consider the stock interesting, further research is recommended. For example, I often monitor director buying and selling.

### How Growth Rates Impact P/E Ratios

Earnings growth rates have a big influence on P/E ratios. 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. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.

Notably, Macmahon Holdings grew EPS by a whopping 43% in the last year. And it has improved its earnings per share by 36% per year over the last three years. With that performance, I would expect it to have an above average P/E ratio.

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

The 'Price' in P/E reflects the market capitalization of the company. 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.

### How Does Macmahon Holdings's Debt Impact Its P/E Ratio?

With net cash of AU\$113m, Macmahon Holdings has a very strong balance sheet, which may be important for its business. Having said that, at 25% of its market capitalization the cash hoard would contribute towards a higher P/E ratio.

### The Verdict On Macmahon Holdings's P/E Ratio

Macmahon Holdings has a P/E of 10. That's below the average in the AU market, which is 17.2. It grew its EPS nicely over the last year, and the healthy balance sheet implies there is more potential for growth. The below average P/E ratio suggests that market participants don't believe the strong growth will continue. Because analysts are predicting more growth in the future, one might have expected to see a higher P/E ratio. You can taker closer look at the fundamentals, here.

Investors should be looking to buy stocks that the market is wrong about. If the reality for a company is not as bad as the P/E ratio indicates, then the share price should increase as the market realizes this.
