A slate of U.S. industrial and transportation companies delivered mixed second-quarter results, underscoring uneven demand across end-markets. Otis Worldwide said net sales were flat year-over-year at $3.6 billion as service revenue growth offset weaker new-equipment demand in China and the Americas. Adjusted earnings of $1.05 a share topped estimates, but the elevator maker cut its full-year revenue forecast, sending the stock down about 13%. Railroad operator CSX reported revenue of $3.57 billion, essentially in line with expectations, while earnings of $0.44 a share beat by two cents despite falling from a year earlier. Management cited better network performance and flat capital-expenditure plans; the shares traded nearly 3% higher before the opening bell. Sector peer Union Pacific exceeded forecasts with $6.20 billion in revenue and earnings of $3.15 a share, producing a 59.0% operating ratio. The company said the results reflected progress on efficiency initiatives and resilient demand in key freight categories. Outside transportation, West Pharmaceutical Services posted a 9.2% increase in quarterly sales to $766.5 million and a 21% jump in adjusted earnings to $1.84 a share, well ahead of consensus. Strong demand for GLP-1 drug components prompted the packaging maker to raise its full-year revenue outlook to as much as $3.06 billion, propelling the stock more than 20% higher. Locomotive and rail-equipment supplier Wabtec earned $2.27 a share on $2.71 billion in revenue, lifted by a 22% surge in modernization orders. The company raised its adjusted earnings guidance for the year as margin expansion and recent acquisitions bolstered its backlog.
