Boeing Co. signaled that several performance issues will weigh on its first quarter results, from fewer-than-planned deliveries of its widebody aircraft and wiring defects on the 737 Max to the cost of turning around a key supplier.

The US planemaker expects the operating margin for its commercial airplane business, Boeing’s largest division, to be around -7.5% during the period that ends March 31, Chief Financial Officer Jay Malave told a Bank of America conference on Tuesday.
