 Shares of Lear Corp. were indicated down nearly 1 in premarket trading Friday, after the auto seating and electronics systems company reported second-quarter profit that beat expectations, revenue that nearly doubled but was shy of forecasts and cut its full-year outlook citing the impact of semiconductor and component shortages. The company swung to net income of 175.2 million, or 2.89 a share, from a loss of 293.9 million, or 4.89 a share, in the year-ago period.
