UZWIL, SWITZERLAND — Mark Macus, Ph.D., has been named chief financial officer of Bühler, effective Sept. 1. Dr. Macus will succeed Andreas Herzog, who plans to retire later this year after 17 years as c.f.o.

“Mark Macus is the ideal successor for us,” said Stefan Scheiber, chief executive officer of Bühler. “He possesses vast experience, knows the challenges of the capital goods industry and is thoroughly familiar with Bühler. We are glad to have found Mark Macus for this task and look forward to welcoming him back.”

Dr. Macus worked for six years at KPMG, was employed for three years in corporate controlling of the Holcim Group and headed the corporate controlling unit of Bühler for five years. He has been the c.f.o. of the Vitra Group in Birsfelden, Switzerland, since April 2018. He has a doctorate degree from the University of St. Gallen and is a certified auditor.

“Withdrawing from the c.f.o. position of Bühler after 17 years is an emotional moment for me,” Mr. Herzog said. “Bühler is a unique organization, in which the family spirit is still alive. But the company must renew itself permanently, and this also impacts my own function.”

In the future, Mr. Herzog said he plans to devote his time and energy to various board mandates and to supporting Bühler in its efforts to develop new business models and its commitment to start-ups.

“We thank Andy cordially for his untiring and passionate commitment, to which Bühler owes much of its success,” said Calvin Grieder, chairman of the board.
