Why Does AAR Spark Debate?

The first third-party MRO approved by the FAA for Safety Management System Requirements, AAR (NYSE: AIR) is a provider of aircraft maintenance services

Two Positive Attributes:

1. Skyrocketing Revenue Shows Strong Momentum

A company’s long-term performance is an indicator of its overall quality. Any business can have short-term success, but a top-tier one grows for years. Over the last five years, AAR grew its sales at an impressive 10.8% compounded annual growth rate. Its growth beat the average industrials company and shows its offerings resonate with customers.

2. Outstanding Long-Term EPS Growth

We track the long-term change in earnings per share (EPS) because it highlights whether a company’s growth is profitable.

AAR’s EPS grew at an astounding 25.6% compounded annual growth rate over the last five years, higher than its 10.8% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.

One Reason to be Careful:

Breakeven Free Cash Flow Limits Reinvestment Potential

Free cash flow isn't a prominently featured metric in company financials and earnings releases, but we think it's telling because it accounts for all operating and capital expenses, making it tough to manipulate. Cash is king.

AAR broke even from a free cash flow perspective over the last five years, giving the company limited opportunities to return capital to shareholders.

Final Judgment

AAR’s positive characteristics outweigh the negatives, and with the recent rally, the stock trades at 22.6× forward P/E (or $115.46 per share). Is now the right time to buy? See for yourself in our in-depth research report, it’s free.
