Aerospace

Aerospace companies often possess technical expertise and have made significant capital investments to produce complex products. It is an industry where innovation is important, and lately, emissions and automation are in focus, so companies that boast advances in these areas can take market share. On the other hand, demand for aerospace products can ebb and flow with economic cycles and geopolitical tensions, which can be particularly painful for companies with high fixed costs.

Sales Growth

A company’s long-term sales performance can indicate its overall quality. Any business can put up a good quarter or two, but many enduring ones grow for years. Unfortunately, AAR’s 3.2% annualized revenue growth over the last five years was sluggish. This fell short of our benchmark for the industrials sector, but there are still things to like about AAR.

We at StockStory place the most emphasis on long-term growth, but within industrials, a half-decade historical view may miss cycles, industry trends, or a company capitalizing on catalysts such as a new contract win or a successful product line. AAR’s annualized revenue growth of 18.1% over the last two years is above its five-year trend, suggesting its demand recently accelerated.

AAR also breaks out the revenue for its three most important segments: Parts Supply, Repair & Engineering, and Integrated Solutions, which are 39.9%, 33.3%, and 23.8% 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 17.6% while its Repair & Engineering (maintenance, repair, and overhaul services) and Integrated Solutions (fleet management) revenues averaged 32.1% and 13.9%.

This quarter, AAR reported robust year-on-year revenue growth of 25.8%, and its $686.1 million of revenue topped Wall Street estimates by 4.9%.

Looking ahead, sell-side analysts expect revenue to grow 9.3% over the next 12 months, a deceleration versus the last two years. Despite the slowdown, this projection is healthy and implies the market sees success for its products and services.

Here at StockStory, we certainly understand the potential of thematic investing. Diverse winners from Microsoft (MSFT) to Alphabet (GOOG), Coca-Cola (KO) to Monster Beverage (MNST) could all have been identified as promising growth stories with a megatrend driving the growth. So, in that spirit, we’ve identified a relatively under-the-radar profitable growth stock benefiting from the rise of AI, available to you FREE via this link.

Operating Margin

AAR was profitable over the last five years but held back by its large cost base. Its average operating margin of 4.8% was weak for an industrials business.

On the plus side, AAR’s operating margin rose by 3.3 percentage points over the last five years.

This quarter, AAR’s breakeven margin was down 7.4 percentage points year on year. This contraction shows it was recently less efficient because its expenses grew faster than its revenue.

Earnings Per Share

We track the long-term change in earnings per share (EPS) for the same reason as long-term revenue growth. Compared to revenue, however, EPS highlights whether a company’s growth is profitable.

AAR’s EPS grew at an unimpressive 6.7% compounded annual growth rate over the last five years. On the bright side, this performance was better than its 3.2% annualized revenue growth and tells us the company became more profitable on a per-share basis as it expanded.

Diving into the nuances of AAR’s earnings can give us a better understanding of its performance. As we mentioned earlier, AAR’s operating margin declined this quarter but expanded by 3.3 percentage points over the last five years. This was the most relevant factor (aside from the revenue impact) behind its higher earnings; taxes and interest expenses can also affect EPS but don’t tell us as much about a company’s fundamentals.

Like with revenue, we analyze EPS over a shorter period to see if we are missing a change in the business.

For AAR, its two-year annual EPS growth of 14.2% was higher than its five-year trend. This acceleration made it one of the faster-growing industrials companies in recent history.

In Q4, AAR reported EPS at $0.90, up from $0.82 in the same quarter last year. This print beat analysts’ estimates by 6.9%. Over the next 12 months, Wall Street expects AAR’s full-year EPS of $3.50 to grow 17.3%.
