Company Overview
Also known as Wabtec, Westinghouse Air Brake Technologies (NYSE: WAB) provides equipment, systems, and related software for the railway industry.
Revenue Growth
Examining a company’s long-term performance can provide clues about its quality. Any business can experience short-term success, but top-performing ones enjoy sustained growth for years. Over the last five years, Wabtec grew its sales at a solid 9.5% compounded annual growth rate. Its growth surpassed the average industrials company and shows its offerings resonate with customers, a great starting point 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. Wabtec’s annualized revenue growth of 8.7% over the last two years aligns with its five-year trend, suggesting its demand was stable. 
This quarter, Wabtec’s revenue grew by 8.1% year on year to $3.12 billion, missing Wall Street’s estimates.
Looking ahead, sell-side analysts expect revenue to grow 7.9% over the next 12 months, similar to its two-year rate. This projection is above the sector average and implies its newer products and services will help sustain its recent top-line performance.

Operating Margin
Operating margin is a key measure of profitability. Think of it as net income - the bottom line - excluding the impact of taxes and interest on debt, which are less connected to business fundamentals.
Wabtec has been an efficient company over the last five years. It was one of the more profitable businesses in the industrials sector, boasting an average operating margin of 15.1%. This result isn’t too surprising as its gross margin gives it a favorable starting point.
Analyzing the trend in its profitability, Wabtec’s operating margin rose by 4.5 percentage points over the last five years, as its sales growth gave it operating leverage.
This quarter, Wabtec generated an operating margin profit margin of 20%, up 3 percentage points year on year. The increase was encouraging, and because its operating margin rose more than its gross margin, we can infer it was more efficient with expenses such as marketing, R&D, and administrative overhead.
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.
Wabtec’s EPS grew at 20.6% compounded annual growth rate over the last five years, higher than its 9.5% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.
We can take a deeper look into Wabtec’s earnings to better understand the drivers of its performance. As we mentioned earlier, Wabtec’s operating margin expanded by 4.5 percentage points over the last five years. On top of that, its share count shrank by 10.2%. These are positive signs for shareholders because improving profitability and share buybacks turbocharge EPS growth relative to revenue growth. 
Like with revenue, we analyze EPS over a shorter period to see if we are missing a change in the business.
For Wabtec, its two-year annual EPS growth of 18.6% was lower than its five-year trend. We still think its growth was good and hope it can accelerate in the future.
In Q3, Wabtec reported adjusted EPS of $2.83, up from $2.32 in the same quarter last year. This print beat analysts’ estimates by 3.5%. Over the next 12 months, Wall Street expects Wabtec’s full-year EPS to grow 15.2% from $10.40 to $11.98.
Key Takeaways from Wabtec’s Q3 Results
