Mahlo GmbH + Co. KG, a global leader in measurement and control systems for web-based materials, has announced a significant leadership transition. Stefan Moll will assume the role of Chief Executive Officer from January 1, 2026, as part of a structured succession plan aimed at securing the company’s long-term market strength and technological leadership.
The appointment follows the planned departure of Rainer Mestermann, who will step down after nearly 14 years at the helm of the machinery manufacturer. The ownership family expressed deep appreciation for Mestermann’s contribution to Mahlo’s growth and international success over the past decade and a half.
Welcoming the new CEO, Ralph Greenwood-Mahlo, owner of Mahlo, said that Stefan Moll brings valuable expertise, fresh thinking and strategic insight to the traditional family-run company. His experience spans both international industrial groups and large, medium-sized family enterprises, giving him a strong understanding of long-term, sustainable business development.
Prior to joining Mahlo, Moll served as Technical Managing Director at the Kiefel Group in Freilassing, a global system supplier for plastic processing, thermoforming and welding technologies. In this role, he was responsible for driving technical innovation, shaping the company’s digital strategy and managing one of its worldwide operating divisions.
Describing himself as an innovation-driven leader, Moll sees his new role as an opportunity to guide Mahlo through a critical phase of strategic transformation. His focus will be on strengthening profitability, ensuring future readiness and motivating employees, customers and stakeholders through a clear and forward-looking strategy.
With this leadership change, Mahlo reinforces its commitment to innovation, sustainable growth and international expansion. Together with the existing management team, Stefan Moll is expected to continue the company’s innovation-driven path and further consolidate its global market position.
