Experienced manager Horst Kayser is set to take charge of Siemens' struggling factory automation division.

The 64-year-old will assume the role on October 1, succeeding Rainer Brehm, who is moving up the corporate ladder, a Siemens spokesperson confirmed on Friday. The investor portal "The Market" was the first to report the personnel change. Brehm will serve as Chief Operating Officer (COO), overseeing day-to-day operations of the automation businesses within the Digital Industries division--a newly created position. The factory automation segment has faced sluggish business for several quarters, putting pressure on Digital Industries' profit margins. The Digital Industries division is led by board member Cedrik Neike.

Kayser previously led the successful restructuring and sale of Siemens' so-called "Portfolio Companies," which comprised non-core businesses of the Munich-based technology group. With the completion of these divestitures, his previous role has become obsolete. "Kayser has extensive experience in factory automation," the spokesperson noted.
