MILAN (Reuters) -Stellantis' ( STLA ) Antonio Filosa on Monday unveiled a new management team on his first day as CEO for the world's fourth largest carmaker, saying he would retain the role of chief for the key North America market.

Stellantis ( STLA ) announced Filosa's appointment at the end of May, following a six-month quest to replace former CEO Carlos Tavares who stepped down in December after overseeing a fall in profits and sales.

CFO Doug Ostermann was confirmed in his role, taking additional responsibility for mergers and acquisitions and joint ventures, the company said in a statement.
