Stellantis NV has named Antonio Filosa as its new CEO, a company veteran with US experience, to reverse the company's slump in the US market due to an aging lineup, model delays, and pricing blunders. Filosa faces significant challenges, including President Donald Trump's tariff moves, increasing competition from Chinese manufacturers, and the need to set a clear strategy to move the company forward, particularly in North America where shipments cratered 20% in the first quarter. Filosa must address issues such as rebuilding quality, margins, and volumes, as well as mounting challenges in Europe, where Stellantis is contending with high energy and labor costs, muted sales, and increased competition.
