Fiat Chrysler shares drop as CEO exit creates uncertainty

Financial investors sent shares in Fiat Chrysler tumbling 4 per cent today as they weighed the potential impact of the accelerated exit of CEO Sergio Marchionne due to serious health issues.

Shares in the Italian-American carmaker were trading at 16.10 euros in volatile trading in Milan. Ferrari, where Marchionne was also replaced at the helm, shed 5 per cent to 113.50 euros on opening.

The losses weighed on the Milan stock exchange overall, where the heft of FCA pulled down the benchmark FTSE MIB by 1.1 per cent.

The FCA board on Saturday named long-time Jeep executive Mike Manley as CEO, unexpectedly accelerating a transition that was planned for early next year.

The company said the 66-year-old Marchionne suffered complications from shoulder surgery last month that meant he could not resume his duties. No other details were released.

Boards also named replacements for Marchionne as Ferrari CEO and CNH Industrial chairman. Louis Camilleri, a chairman at Ferrari sponsor Philip Morris, is the new Ferrari CEO, while Suzanne Heywood takes over as CNH Industrial chair.

Manley's first appointment in the role is at a regular FCA executive council meeting in Turin today, and his first public appearance will be to present FCA's second quarter earnings on Wednesday.

Marchionne had announced in his last major presentation to analysts last month that the quarterly results would show FCA at zero debt for the first time -- an occasion for which the normally casually attired Italian-Canadian manager donned a tie -- even if only briefly.

The five-year plan included a significant shift to electrified motors. Marchionne engineered both the turnarounds of Italian carmaker Fiat, which he took over in 2004, and Chrysler, which Fiat acquired in 2009 in a deal with the US government, creating the world's seventh-largest carmaker out of two formerly dysfunctional entities.

He created shareholder value for the Fiat founding Agnelli family with successful spinoffs of Fiat's heavy vehicle maker CNH Industrial and of the iconic Ferrari super sports car company.

But his goal of another big merger failed to find any takers. Manley, 54, has been key to transforming the quintessentially American Jeep brand into a global marquee since taking over there in 2009, and he also has been the head of the Ram truck division since 2015.

Both brands have formed the leading edge of FCA's North American strategy to move away from passenger car production and focus on SUVs and trucks to meet market demand.

"Although Mr Manley's public profile has been relatively low and limited to operational matters, he was heavily involved in setting the 2019-22 strategic plan," Philippe Houchois, an analyst at Jeffries Financial Services, said in a note. "We expect continuity."
