MILAN, Sept 7 (Reuters) - Exor, the holding company of Italy's Agnelli family, said on Tuesday it turned to a profit in the first half of this year, thanks to the strong performance of the companies it has invested in.

Exor said its consolidated profit totalled 838 million euros ($993 million) in the January-June period, despite a 504 million euro non-recurring loss linked to the deconsolidation of Fiat Chrysler, following its merger with PSA to form Stellantis .

This compares with a 1.318 billion loss in the first half of last year, mainly attributable to the COVID-19 pandemic.

Exor is the single largest investor in carmaker Stellantis and has controlling stakes in Ferrari, CNH Industrial and Juventus football club.

It said its net asset value rose 9% in the first half, to $32.158 billion at the end of June.
