What Is Macquarie Infrastructure's (NYSE:MIC) P/E Ratio After Its Share Price Tanked?

Unfortunately for some shareholders, the Macquarie Infrastructure (NYSE:MIC) share price has dived 37% in the last thirty days. That drop has capped off a tough year for shareholders, with the share price down 32% in that time.

All else being equal, a share price drop should make a stock more attractive to potential investors. While the market sentiment towards a stock is very changeable, in the long run, the share price will tend to move in the same direction as earnings per share. So, on certain occasions, long term focussed investors try to take advantage of pessimistic expectations to buy shares at a better price. Perhaps the simplest way to get a read on investors' expectations of a business is to look at its Price to Earnings Ratio (PE Ratio). Investors have optimistic expectations of companies with higher P/E ratios, compared to companies with lower P/E ratios.

Macquarie Infrastructure's P/E tells us that market participants think the company will perform better than its industry peers, going forward. The market is optimistic about the future, but that doesn't guarantee future growth. So investors should always consider the P/E ratio alongside other factors, such as whether company directors have been buying shares.

How Growth Rates Impact P/E Ratios

Companies that shrink earnings per share quickly will rapidly decrease the 'E' in the equation. That means unless the share price falls, the P/E will increase in a few years. Then, a higher P/E might scare off shareholders, pushing the share price down.

Notably, Macquarie Infrastructure grew EPS by a whopping 47% in the last year. In contrast, EPS has decreased by 41%, annually, over 5 years.

Remember: P/E Ratios Don't Consider The Balance Sheet

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. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.

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 Macquarie Infrastructure's Debt Impact Its P/E Ratio?

Macquarie Infrastructure's net debt is 97% of its 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 Macquarie Infrastructure's P/E Ratio

Macquarie Infrastructure's P/E is 23.5 which is above average (13.3) in its market. Its meaningful level of debt should warrant a lower P/E ratio, but the fast EPS growth is a positive. So despite the debt it is, perhaps, not unreasonable to see a high P/E ratio. Given Macquarie Infrastructure's P/E ratio has declined from 37.6 to 23.5 in the last month, we know for sure that the market is significantly less confident about the business today, than it was back then. For those who don't like to trade against momentum, that could be a warning sign, but a contrarian investor might want to take a closer look.
