Stellantis CEO Carlos Tavares has unexpectedly resigned from the automaker amid increasingly “different views” between the executive and the board of directors, the company said Sunday.

Carlos Tavares is stepping down as Chief Executive Officer of Stellantis, effective immediately, following a sharp decline in the carmaker’s sales. As the Wall Street Journal notes, in July, the company reported that its net profit for the first half of the year had dropped by 48 percent compared to 2023.

Stellantis CEO Carlos Tavares abruptly announced his resignation on Sunday after leading the car giant for four years. Its board is already looking for his permanent replacement.
