Zander will step down on January 1, 2008, but will continue to serve as chairman of the board until an annual shareholders meeting in May.
No reason has been given for Zander’s departure, but Motorola lead director Samuel C Scott III said: “I want to take this opportunity to thank Ed for his vision, expertise and tireless commitment to Motorola. We greatly appreciate his many contributions and wish him all the best in the years ahead. Today’s decision is the culmination of a thoughtful and disciplined process of succession planning.”
Since joining the group in 2003, Brown has headed up four different businesses at Motorola and also led the $3.9 billion (£1.9bn) acquisition of Symbol Technologies.
Before joining Motorola, Brown was CEO of network management software company Micromuse Inc, president of Ameritech Custom Business Services and Ameritech New Media Inc. He also held various sales and marketing roles at AT&T.
Brown added: “I welcome this opportunity to lead Motorola successfully into the future. We have a lot to do and I am intensely focused on building shareholder value. I look forward to working closely with Ed to ensure a smooth transition.”
