# Here’s How P/E Ratios Can Help Us Understand Ternium S.A. (NYSE:TX)

Today, we’ll introduce the concept of the P/E ratio for those who are learning about investing. We’ll look at Ternium S.A.’s (NYSE:TX) P/E ratio and reflect on what it tells us about the company’s share price. Ternium has a price to earnings ratio of 2.59, based on the last twelve months. That is equivalent to an earnings yield of about 39%.

### 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)

Or for Ternium:

P/E of 2.59 = \$16.79 ÷ \$6.48 (Based on the trailing twelve months 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 is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.

### Does Ternium Have A Relatively High Or Low P/E For Its Industry?

We can get an indication of market expectations by looking at the P/E ratio. We can see in the image below that the average P/E (11.5) for companies in the metals and mining industry is higher than Ternium’s P/E.

This suggests that market participants think Ternium will underperform other companies in its industry.

### How Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. Earnings growth means that in the future the ‘E’ will be higher. 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.

Ternium increased earnings per share by a whopping 26% last year. And earnings per share have improved by 20% annually, over the last five 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. Thus, the metric does not reflect cash or debt held by the company. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

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).

### How Does Ternium’s Debt Impact Its P/E Ratio?

Net debt totals 53% of Ternium’s market cap. If you want to compare its P/E ratio to other companies, you should absolutely keep in mind it has significant borrowings.

### The Bottom Line On Ternium’s P/E Ratio

Ternium’s P/E is 2.6 which is below average (17.3) in the US market. The company may have significant debt, but EPS growth was good last year. If it continues to grow, then the current low P/E may prove to be unjustified.

When the market is wrong about a stock, it gives savvy investors an opportunity. 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.
