Hertz Global Holdings on Tuesday announced a shakeup of its leadership ranks, naming Kathryn Marinello as its next president and chief executive officer. Marinello, who was most recently a senior adviser to Ares Capital Management, will take over on Jan. 3 for John Tague, who’s retiring from the rental car company. The move pleased activist investor Carl Icahn, Hertz’s largest shareholder, who said he’s “excited about Hertz and its prospects with [Marinello] at the helm.”
