Shares in Fiat Chrysler Automobiles rose more than 8 percent on Wednesday after a Bloomberg report said Samsung Electronics was in advanced talks to buy some or all of the operations of its parts maker Magneti Marelli.
Fiat Chrysler (FCA) declined to comment on the report. Samsung could not immediately be reached for comment.
The source-based report said Samsung was particularly interested in Magneti Marelli's lighting, in-car entertainment and telematics business and could consider an acquisition of the whole company.
The deal could be worth more than $3 billion with a goal of closing this year, the agency added.
Sources told Reuters last year that FCA was considering whether to sell the auto parts maker after receiving interest from potential buyers.
One of the people added at the time that the carmaker had rebuffed one offer as it was not willing to sell the unit for less than 3 billion euros ($3.36 billion).
