A strong quarter supports the move
WAB was still up about 12% as of 1:02 PM ET Wednesday after reporting a strong second quarter and raising its 2026 outlook. The rally has more support than a large backlog headline. Sales, profit margins, and cash flow all moved in the right direction.
Second-quarter sales rose 17.5% to $3.18 billion. Adjusted diluted earnings per share rose 21.6% to $2.76, while adjusted operating margin reached 21.9%. GAAP diluted EPS was $2.33, up 18.9% from a year earlier.
The cash result adds useful backing. Operating cash flow rose to $441 million from $209 million a year earlier. Cash flow can swing with customer payments, inventory, and other working-capital items. Still, this quarter's gain gives the higher earnings figure more weight than an accounting result alone would.
- Revenue guidance rose to $12.30 billion to $12.60 billion, raising the midpoint by $110 million.
- Adjusted EPS guidance increased to $10.60 to $10.90, from $10.25 to $10.65. That is a 35-cent increase at the low end and a 25-cent increase at the high end.
The release gives Wabtec a credible case for its higher outlook. The more delicate question sits in the order book. Investors should separate evidence of stronger operations from the reported backlog growth that arrived with Dellner Couplers.
The large backlog includes acquired work
Wabtec ended June with $30.93 billion of total multi-year backlog. The company said that figure was $9.10 billion above the prior-year level, or 41.3% higher on a constant-currency basis. That is a sizable increase, but it is not a clean measure of orders won by the pre-acquisition company.
Wabtec bought Dellner Couplers on February 10 for about $1.053 billion, funded with cash and borrowings. Dellner's acquired intangible assets included backlog subject to amortization. Some part of Wabtec's larger reported order base therefore came with the acquired business.
Transit sales show the same mixed picture. They rose 18.9% in the second quarter, with Wabtec citing Dellner, higher original-equipment and aftermarket sales, and foreign exchange as contributors. The acquisition may add useful products and customer relationships. But the reported growth does not isolate organic demand, and it should not be treated as if one driver explains the whole result.
The 12-month backlog rose 11.3% from a year earlier. That is the more relevant figure for near-term revenue visibility, though Wabtec did not disclose how much of that gain came from Dellner. It is a cleaner time horizon than the multi-year total, not proof of purely organic growth.
Industrial investors have seen this distinction before. A large order book can be real and still leave the key economic question unanswered: can it convert into profitable work? Wabtec's quarter suggests it can. The next reports need to show that the answer holds as Dellner becomes part of normal comparisons.
Cash conversion now meets the balance sheet
Dellner changed more than the backlog. Wabtec ended the quarter with $6.57 billion of total debt and about $670 million of cash, cash equivalents, and restricted cash. Those balances make sustained cash generation more important after a deal financed with both cash and borrowings.
The $441 million of quarterly operating cash flow is an encouraging start, but it is not yet a new run rate. Working capital, which reflects the timing of cash collected from customers and cash spent on inventory and other needs, can make one quarter look stronger or weaker than the underlying business.
The countercase is straightforward. If Transit growth slows once acquisition effects fade, or if Dellner's work carries lower margins than Wabtec's existing operations, the larger backlog will not produce the earnings and debt flexibility investors expect. The current results do not establish either outcome.
Third-quarter results are the next hard check. The useful signals will be whether Transit growth becomes clearer on a comparable basis, whether the 12-month backlog turns into revenue without pressure on margins, and whether operating cash flow stays solid as Dellner moves beyond its first full quarters inside Wabtec.
