Leadership Transition at ArcelorMittal

In a significant management shift, ArcelorMittal has announced the appointment of Rainer Böse as the new Chief Executive Officer for its Bremen and Eisenhüttenstadt facilities in Germany. The decision was made official by the Supervisory Boards of both sites, with Böse stepping into the role with immediate effect. He takes over from Dr. Thomas Bünger, who had served the steelmaker with dedication for several years.

A Veteran of the Steel Industry

At 57, Rainer Böse brings more than two decades of deep-rooted experience in the steel industry, particularly within ArcelorMittal’s Northern Europe operations. Holding a degree in economics, Böse has built a robust career spanning leadership roles in sales, finance, and business development. From 2009 to 2016, he served as the Managing Director of ArcelorMittal Commercial Germany GmbH, laying the groundwork for strategic commercial operations across the country.

Recent Role as Chief Marketing Officer

Most recently, Böse held the position of Chief Marketing Officer for the Industry division in Northern Europe, a role he occupied from 2017 until his latest promotion. His tenure in this capacity saw him steering marketing strategy and client engagement during a period marked by increased demand for green steel, supply chain disruptions, and evolving energy regulations across the European Union.

Deep Knowledge of the Flat Steel Market

Rainer Böse’s appointment is seen as a strategic move to further strengthen ArcelorMittal’s leadership in the flat steel sector. His expertise is especially valued as the company navigates the complexities of decarbonization, including its transition to low-CO₂ production methods and investments in H₂-based steelmaking technologies. His familiarity with German market dynamics positions him well to align operations with the growing demand for sustainable, high-performance steel.

Statement from Company Leadership

“We are delighted to have found a successor in Rainer Böse who knows the Group very well and has international connections,” said the management teams at Bremen and Eisenhüttenstadt. “We would like to thank Dr. Bünger sincerely for his dedicated service to our company.” The boards expressed full confidence in Böse’s leadership and wished him success in steering the plants through a new chapter of industrial evolution.

Legacy of Dr. Thomas Bünger

Dr. Bünger’s tenure at the helm of the Bremen and Eisenhüttenstadt sites saw significant operational modernization and a strong focus on digital transformation. He was instrumental in aligning the German plants with ArcelorMittal’s global decarbonization roadmap. His departure is marked with appreciation and respect, with both the Executive and Supervisory Boards commending his vision and integrity.

Navigating Industrial Transformation

As the global steel industry shifts toward greener and smarter production, Rainer Böse’s appointment is expected to reinforce ArcelorMittal’s commitment to innovation and sustainability in Germany. Under his leadership, the two plants are expected to prioritize digital infrastructure, energy efficiency, and emission reduction as central components of their forward-looking strategies.

Strategic Importance of the Sites

The Bremen and Eisenhüttenstadt facilities are critical nodes in ArcelorMittal’s European production network. Together, they contribute millions of metric tons of flat steel annually to the automotive, machinery, and construction sectors. Böse’s elevation to CEO reflects ArcelorMittal’s intent to fortify its operations in a region increasingly focused on circular economy models and green industrial policies.
