Verizon’s new boss is officially taking the reins. Hans Vestberg on Wednesday took over as CEO, as Verizon fights to be the first to roll out 5G service. Vestberg was Verizon’s chief technology officer before the promotion. The company announced in June that its former CEO Lowell McAdam would step down and that Vestberg would succeed him on Aug. 1. Born in Hudiksvall, Sweden, Vestberg served as the CEO of Swedish telecommunications giant Ericsson for six years before joining Verizon last year. Verizon is racing against AT&T and T-Mobile to deploy next-generation 5G coverage and stake new claims of network superiority. Vestberg has been involved in Verizon’s strategic decisions regarding 5G, according to the company’s blog post. Verizon didn’t immediately respond to a request for comment.
