The net strike impact to fourth quarter EBIT-adjusted (earnings before interest and taxes) was $2.6 billion, or $1.39 per diluted-adjusted share.
For the full year, the strike reduced EBIT-adjusted by $3.6 billion and lowered adjusted auto free cash flow by $5.4 billion, GM also said.
GM lost $194 million in the final quarter, largely due to the strike.
The automaker reported $137.2 billion in net revenue for the entire year, down 6.7 percent for the same measure in 2018. The company also saw $6.7 billion in income for the year, down 17.4 percent compared to 2018.
Despite the strike, GM said its “underlying performance remained strong, driven by sales of GM’s all-new full-size pickups and the company’s ongoing cost actions.”
Full-size pickup and heavy-duty pickup sales are important to the Dayton area. The DMAX diesel truck engine is an option on a series of heavy-duty GM and GMC trucks. The Chevrolet Silverado 2500HD can be equipped with the 6.6-liter Duramax turbo-diesel engine, for example.
