Voser, the former Royal Dutch Shell CEO who took temporary charge at ABB in April, said the company, whose operations run from factory robots to chargers for electric cars, was ready to make further cuts to its portfolio if necessary. "If we feel the need to separate ourselves from one area, then we do that as well," Voser said in article published by German newspaper Boersen-Zeitung. "If we see a strategic need, we can act," he said. "I can not say if ABB will look like it does now in five years." The comments, confirmed by ABB, boosted the company's shares, which were 2.5% higher and the biggest gainer on Switzerland's blue chip index. The synergies between the ABB's electrification, industrial automation, drive technology and robotics divisions "are not so great," Voser said in the article. But he added that a separation of the electrification division, currently ABB's biggest business by sales, was not being considered. A separation is "not at the moment on the table with us," said Voser.
