 The chip shortage and supply chain disruptions may have put pressure on Wabtecs freight segment in the third quarter, but the underlying demand is still there and should bode well for the company in the fourth quarter, executives said during Wabtecs third-quarter 2021 earnings call Wednesday. We believe that the underlying customer demand for our products and the end market momentum remains strong even though there may be continued headwinds from a more challenging sales and cost environment in the fourth quarter, said Wabtec NYSE: WAB President and CEO Rafael Santana.
