UPDATE 1-Stellantis operating profit down 10% in H2 due to N. America strikes

Stellantis warned on Thursday of a "turbulent" year ahead as its operating profit fell 10% in the second half, when strikes at the 'Detroit Three' automakers caused long stoppages at its operations in North America, its profit powerhouse. Union strikes in North America added to a complicated outlook for global carmakers, with still timid global demand for electric vehicles, increasing Chinese competition, sustained costs and fallouts from geopolitical tensions. Unions' coordinated six-week strikes in the United States and Canada ended with agreements for record salary increases for workers at the Detroit Three automakers.
