Revenue Growth

A company’s long-term performance is an indicator of its overall quality. Any business can put up a good quarter or two, but the best consistently grow over the long haul. Over the last five years, AAR grew its sales at a mediocre 6.1% compounded annual growth rate. This was below our standard for the industrials sector and is a poor baseline for our analysis.

Long-term growth is the most important, but within industrials, a half-decade historical view may miss new industry trends or demand cycles. AAR’s annualized revenue growth of 18.2% over the last two years is above its five-year trend, suggesting its demand recently accelerated. We note AAR isn’t alone in its success as the Aerospace industry experienced a boom, with many similar businesses also posting double-digit growth.

We can better understand the company’s revenue dynamics by analyzing its three most important segments: Parts Supply, Repair & Engineering, and Integrated Solutions, which are 40.5%, 29.5%, and 26.5% of revenue. Over the last two years, AAR’s revenues in all three segments increased. Its Parts Supply revenue (engine and airframe parts) averaged year-on-year growth of 16.8% while its Repair & Engineering (maintenance, repair, and overhaul services) and Integrated Solutions (fleet management) revenues averaged 31.1% and 13%.

This quarter, AAR reported year-on-year revenue growth of 14.9%, and its $754.5 million of revenue exceeded Wall Street’s estimates by 8.6%.

Looking ahead, sell-side analysts expect revenue to grow 2.5% over the next 12 months, a deceleration versus the last two years. This projection is underwhelming and suggests its products and services will see some demand headwinds.

Operating Margin

Operating margin is an important measure of profitability as it shows the portion of revenue left after accounting for all core expenses – everything from the cost of goods sold to advertising and wages. It’s also useful for comparing profitability across companies with different levels of debt and tax rates because it excludes interest and taxes.

AAR was profitable over the last five years but held back by its large cost base. Its average operating margin of 6.1% was weak for an industrials business.

On the plus side, AAR’s operating margin rose by 1.5 percentage points over the last five years, as its sales growth gave it operating leverage.

In Q2, AAR generated an operating margin profit margin of 9.7%, up 4.7 percentage points year on year. This increase was a welcome development and shows it was more efficient.

Earnings Per Share

Revenue trends explain a company’s historical growth, but the long-term change in earnings per share (EPS) points to the profitability of that growth – for example, a company could inflate its sales through excessive spending on advertising and promotions.

AAR’s EPS grew at a remarkable 12.8% compounded annual growth rate over the last five years, higher than its 6.1% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.

Diving into AAR’s quality of earnings can give us a better understanding of its performance. As we mentioned earlier, AAR’s operating margin expanded by 1.5 percentage points over the last five years. This was the most relevant factor (aside from the revenue impact) behind its higher earnings; interest expenses and taxes can also affect EPS but don’t tell us as much about a company’s fundamentals.

Like with revenue, we analyze EPS over a more recent period because it can provide insight into an emerging theme or development for the business.

For AAR, its two-year annual EPS growth of 16.4% was higher than its five-year trend. We love it when earnings growth accelerates, especially when it accelerates off an already high base.

In Q2, AAR reported EPS at $1.16, up from $0.88 in the same quarter last year. This print easily cleared analysts’ estimates, and shareholders should be content with the results. Over the next 12 months, Wall Street expects AAR’s full-year EPS of $3.90 to grow 15.6%.
