The company's pre-tax operating profit in the third quarter was negatively impacted by less than 750 million euros ($795 million) by the strikes over pay increases, Stellantis said on Tuesday.
Third-quarter revenue rose 7 percent to 45.1 billion euros ($47.8 billion), the company said in a statement on Tuesday.
The increase was mainly due to higher volumes, stable pricing, improving logistics and robust demand for models such as the electric Jeep Avenger but was partially offset by foreign exchange rates, Stellantis said.
Consolidated shipments rose 11 percent in the quarter to 1.48 million vehicles.
Chief Financial Officer Natalie Knight, who started the job in the summer, said on a media call on Tuesday that the 750 million euro impact on profitability from the strikes was the smallest among the Detroit Three.
"We are looking at everything in terms of where should we approach (mitigation actions). And I think you will continue to hear more about that mitigation as we go forward," she said.
Stellantis has canceled plans for U.S. events including the CES consumer-trade show in January and will continue to cut costs to make up for the strike hit, Knight said.
The UAW's unprecedented six-week campaign of coordinated strikes in the U.S., which started last month and expanded in October, are ending this week after tentative agreements that won record salary increases for workers at the Detroit 3 automakers.
