Markus Siegner has been appointed as the new CEO of Kögel Trailer, effective from 1 January 2026.
He succeeds Christian Renners, who left the company in September 2025.
In this new role, Siegner will also be responsible for operations, supply chains, development and logistics and will focus on increasing customer value through digital and electronic solutions, promoting sustainable business practices and further enhancing the company’s productivity.
Siegner brings more than 25 years of international management experience in industry, with a proven track record in operations, global production networks, supply chain management, procurement and post-merger integration.
In his most recent role as COO of AL-KO Vehicle Technology, he was responsible for global operations with four business units, more than 25 production sites and over 3,000 employees.
Under his leadership, the company implemented comprehensive transformation and efficiency programs, including significant reductions in productivity costs and material costs, site optimisations and the operational integration of several acquisitions.
Prior to this, Siegner held various senior management positions at OSRAM over many years, including COO of a global business unit, VP of Manufacturing & Procurement, and other management roles in Europe and Asia.
He managed international production and supply networks, achieved significant cost reductions and efficiency gains, established new locations, and drove forward strategic footprint optimisations and digital transformation programs.

“The highly dynamic nature of international markets requires continuous development of the company to remain successful with new and improved products, processes and sales concepts,” said Siegner.
“To this end, digital transformation offers enormous potential. Together with the Kögel team and our customers, I want to drive the next phase of success across products, production and supply chains.
“For me, people are at the heart of everything we do — Kögel’s success is down to the dedication of the people who work here.”
In his new role, Siegner plans to continue advancing the strategic direction of Kögel Trailer GmbH, with a particular focus on innovation, sustainable growth, digitalisation and expanding market presence.
This includes programs to increase productivity, enhance customer value through digital and electronic solutions, and strengthen sustainable business practices for the environment, customers and employees.
