The Bühler Group Board appointed Samuel Schär as the new CEO as of January 2026, reinforcing its commitment to its long-term orientation as a family business with this succession plan.

With a background in physics, Samuel Schär joined Bühler 20 years ago to establish the Nanotechnology business unit. He then led the Grinding & Dispersing business area for several years, before joining the Group Executive Board in 2013. He led the Advanced Materials segment for 10 years and later took over responsibility for the Global Services & Sales organization.  

In parallel, the Board of Directors has decided to propose Stefan Scheiber, the Group’s current CEO, as the new Chairman of the Board of Directors of Bühler Group at the next Annual General Meeting in February 2026. Stefan Scheiber has had a 35-year career at Bühler in Switzerland and abroad. He has been a member of Group Management for 20 years in various areas of responsibility and will have held the position of CEO for 10 years at the end of this year.  

Stefan Scheiber will succeed Calvin Grieder. Calvin Grieder will step down at the 2026 Annual General Meeting after 25 years as CEO, Member of the Board of Directors, and Chairman of the Board of Directors of Bühler Group.  

This long-term succession plan follows the transition initiated years ago within the owner family by Urs Bühler, the company reveals. The fifth generation of the family – Karin, Maya, and Jeannine Bühler – are continuing the long-term ownership strategy. Bühler will remain in the ownership of the family and will remain an independent, globally active technology company.
