Company Overview

Also known as Wabtec, Westinghouse Air Brake Technologies (NYSE: WAB) provides equipment, systems, and related software for the railway industry.

Revenue Growth

A company’s long-term sales performance is one signal of its overall quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Luckily, Wabtec’s sales grew at a solid 9.1% compounded annual growth rate over the last five years. Its growth surpassed the average industrials company and shows its offerings resonate with customers, a great starting point for our analysis.

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. Wabtec’s recent performance shows its demand has slowed as its annualized revenue growth of 7.4% over the last two years was below its five-year trend. We’re wary when companies in the sector see decelerations in revenue growth, as it could signal changing consumer tastes aided by low switching costs.

We can better understand the company’s sales dynamics by analyzing its organic revenue, which strips out one-time events like acquisitions and currency fluctuations that don’t accurately reflect its fundamentals. Over the last two years, Wabtec’s organic revenue averaged 7.1% year-on-year growth. Because this number aligns with its two-year revenue growth, we can see the company’s core operations (not acquisitions and divestitures) drove most of its results.

This quarter, Wabtec’s year-on-year revenue growth was 13%, and its $2.95 billion of revenue was in line with Wall Street’s estimates.

Looking ahead, sell-side analysts expect revenue to grow 8.9% over the next 12 months, an improvement versus the last two years. This projection is above average for the sector and indicates its newer products and services will spur better top-line performance.

Operating Margin

Operating margin is one of the best measures of profitability because it tells us how much money a company takes home after procuring and manufacturing its products, marketing and selling those products, and most importantly, keeping them relevant through research and development.

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 14.2%.

Looking at the trend in its profitability, Wabtec’s operating margin rose by 4.3 percentage points over the last five years, as its sales growth gave it operating leverage.

In Q1, Wabtec generated an operating margin profit margin of 17.5%, in line with the same quarter last year. This indicates the company’s cost structure has recently been stable.

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 9.1% 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 was flat this quarter but expanded by 4.3 percentage points over the last five years. On top of that, its share count shrank by 9.6%. 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 19.9% is similar to its five-year trend, implying strong and stable earnings power.

In Q1, Wabtec reported adjusted EPS of $2.71, up from $2.28 in the same quarter last year. This print beat analysts’ estimates by 7.6%. We also like to analyze expected EPS growth based on Wall Street analysts’ consensus projections, but there is insufficient data.

Key Takeaways from Wabtec’s Q1 Results

While organic revenue missed by a bit and revenue was just in line, backlog (a leading indicator of future revenue) beat. It was also encouraging to see Wabtec beat analysts’ EPS expectations this quarter. Lastly on the positive side, full-year EPS guidance was raised. Overall, this was a solid quarter despite not being a perfect one. The stock traded up 2.4% to $263.87 immediately following the results.
