Wabtec Raises Guidance as Flow Business and a New Data-Center Niche Emerge

A Beat That Wasn't Just Timing

Wabtec's Q2 results were ahead of plan, and the company raised full-year EPS guidance by $0.30 to a $10.75 midpoint. The headline growth was strong—sales up 17.5%—but the more important detail is that roughly half of that came from organic growth, driven by what management calls the flow business (parts, services, and other turn revenue tied to carloads). CFO John Olin noted this is a sustainable acceleration: “When we look at the Q2, revenue was ahead of expectations as well as earnings. When we look at revenue was driven by a couple things. Number one, on more of a sustainable basis, we saw our flow businesses accelerate.” — John Olin, Chief Financial Officer (CFO) · 2026-07-22 The 12-month backlog is up 11% and the multiyear backlog jumped 42% to over $30 billion, giving unusual visibility.

Margin expansion was also better than expected. Adjusted operating margin rose 0.8pp to 21.9% despite tariff headwinds and unfavorable mix. Management expects the majority of margin growth to land in Q4, as Olin explained: “We expect growth in the Q3, but that's going to be in the range of around a half a point that we saw in the H1 of the year. Why is the Q4 going to be up so much? … We're lapping those two things that aren't going to repeat again this year, [and] the tariff expense is going to be pretty even between quarters this year.” — John Olin, Chief Financial Officer (CFO) · 2026-07-22 This is a notable departure from the prior quarter, when tariffs were still a rising drag. On the April call, Olin had said: “We're going to feel margin pressure in the first half of the year because of tariffs and that pressure will dissipate in the back half.” — John Olin, Chief Financial Officer (CFO) · 2026-04-22 The Q2 guide raise suggests that dissipation is now showing up early.

Data Centers: A Quiet New Door

The most unusual new theme this quarter is data center-adjacent demand. Wabtec's heat exchangers, which sit inside its components business, are benefiting from power-generation demand (a sector that data centers are driving). CEO Rafael Santana was careful to set expectations:

Heat exchangers is a positive for us. You're seeing that as a significant offset to some of the pressures we've got on the freight car side of the house. In terms of the engine side, when we look at engines specifically, our engines are really built for some of the most demanding applications in the world. … When we think about data centers, a large portion of that is connected to backup power-only applications, which our engines are generally not the most competitive solution for that application. This is very much a niche segment of the market, and at this stage, we have had really only very, very nominal sales in the space.

Product Cycle: EVO Advantage Gets an Order

Another concrete change is the first North American order for the EVO Advantage modernization program, booked in Q2. Rafael: “We've gotten our first order in North America in the Q2, so that's consistent with what we expected. We see that as an opportunity to really continue momentum with regards to refreshing our install base around the world.” — Rafael Santana, Chairman and CEO · 2026-07-22 This is a multi-year product cycle that could unlock a large installed base, especially as the fleet ages. Management emphasized that the multiyear backlog gives strong coverage into 2027 and beyond, with international deals like the $1B Australian order and the $184M PTC order from Vale underpinning the pipeline. In prior quarters, pipeline strength was a recurring theme—back in February, Rafael had said: “We continue to have a very strong pipeline of opportunities, and internationally it's very, very strong.” — Rafael Ottoni Santana, President and Chief Executive Officer (CEO) · 2026-02-11 The difference now is that the pipeline is converting into backlog at a record pace, with the multiyear backlog up 42% year-over-year.

Fundamental Framework

The numbers confirm the narrative. Revenue rose to $3.18B in Q2, but the more telling measure is the operating margin trend: Operating income growth of 27% outpaced revenue, and adjusted operating margin hit 21.9%. The revenue trajectory has been accelerating—up 17.5% this quarter, with organic growth around 8.5%—while the company's cash generation remains strong at $441M and leverage at 2.2x. The one soft spot is the components segment, down 0.7% due to the ongoing North American railcar build slump (still forecast down ~21% for 2026), but heat exchangers helped offset that. Management's ability to hold margins while absorbing tariffs is a testament to the margin growth story, and the raised guidance suggests confidence in that trajectory.

Overall, this quarter offers two clear signals: a durable acceleration in flow revenue that is now embedded in guidance, and the early emergence of a data-center-adjacent market for heat exchangers. Neither is a full pivot, but both are new, company-specific developments that justify a higher valuation multiple—and the stock has responded with an 11% rally over the past 90 days.
