Jefferies analyst Stephen Volkmann believes the sale of Navistar International's (NAV) defense business to Cerberus "clears a potential hurdle" for the truck business to be sold to foreign entity Traton. The analyst says he's long noted his expectation that Navistar will ultimately be sold to Traton, the Volkswagen (VLKAY) Truck & Bus businesses that is on track for initial public offering in Q1 of 2019. Given that foreign acquisitions of U.S. defense businesses are "inherently problematic," Volkmann views yesterday's unit sale as "removing an important potential hurdle." He keeps a Buy rating on Navistar with a $53 price target.
