Boeing Co.’s biggest supplier suspended production after union workers voted to strike, a surprise development that risks disrupting the planemaker’s plan to lift output of its cash-cow 737 Max jet.
Spirit AeroSystems Holdings Inc. slid as much as 15% in New York trading, its biggest intraday drop in two months, after union members rejected a four-year contract proposal supported by their leadership. Boeing, which relies on its former unit to make 737 fuselages and other aircraft assemblies, fell as much as 4%.
