Morgan Stanley analyst Adam Jonas said the fact that Hertz management did not provide financial guidance for 2018 should not be a surprise as the car rental industry "doesn't grow" and the company has total debt "far greater" than its total revenue. He believes management commentary on 2018 suggests elevated turnaround and transition expenses will continue before an improvement in 2019. Jonas, who still thinks Hertz may need to consider significant structural changes given the challenges facing the traditional car rental business model, keeps an Underweight rating on Hertz shares.
