Barra: GM Shareholders Aren’t Interested in FCA Merger

General Motors Co. CEO Mary Barra tells reporters at the Frankfurt auto show the company and its outside advisors have considered the idea of a merger with Fiat Chrysler Automobiles NV "very, very carefully and in tremendous detail."

But she says they remain convinced such a move would not be in GM's best interest. She also notes that GM's major investors haven't responded to FCA CEO Sergio Marchionne's efforts to convince them that a merger would be beneficial.

Marchionne told Automotive News late last month his own calculations estimate the integrated companies would throw off $30 billion in cash per year. He points out that carmakers could save enormous amounts of product development costs by pooling their efforts.

FCA's competitors don't disagree. But analysts say they also don't see merit in partnering specifically with FCA.
