Riedel Expands Leadership Structure, Appoints Marc Engroff as CFO and Frank Eischet as Group COORiedel Communications today announced the expansion of its leadership structure as part of a strategic initiative to strengthen both its operational management and overarching group leadership. As part of this development, Marc Engroff has been appointed Chief Financial Officer (CFO) of Riedel Communications. At the same time, Frank Eischet transitions into the role of Chief Operating Officer (COO) of the Riedel Group, with an increased focus on group-level strategy and cross-functional alignment.

As part of a previously defined evolution of the leadership structure, this move is being implemented at a time of dynamic developments across the broader Riedel environment, including Thomas Riedel's recent acquisition of ARRI, the Munich-based premium manufacturer of camera and lighting technology. It further strengthens the management structure of Riedel Communications while enhancing coordination and governance at the Riedel Group level.

In his new role, Engroff assumes responsibility for key corporate functions including finance, controlling, M&A, global purchasing, and IT. He will play a central part in further developing the company's financial structures and supporting its sustainable growth trajectory. With Engroff taking over operational financial leadership within Riedel Communications, Eischet will dedicate greater focus to overarching priorities across the Riedel Group, including strategic alignment, operational scalability, and the continued development of global structures. He will continue to serve as Managing Director of Riedel Communications alongside Thomas Riedel, jointly representing both the company and the Riedel Group.

Eischet joined Riedel Communications in 2011 as CFO and Managing Director and has played a key role in shaping the company's financial and operational foundation during a period of substantial growth. During his tenure, Riedel has grown from a company with revenues below 50 million to a business generating more than 250 million, alongside significant international expansion and organizational development.

Frank has been instrumental in building the structures that have enabled Riedel's growth over the years, said Thomas Riedel, Riedel Group CEO and founder of Riedel Communications. With Marc, we are appointing a highly capable and trusted leader from our own ranks who combines strong financial expertise with a proven ability to translate data into strategic direction. This evolution strengthens Riedel Communications operationally while further developing our leadership at the Riedel Group level.

Engroff joined Riedel Communications in 2024 and most recently served as Director Group Controlling, where he was instrumental in building and developing the company's controlling structures and processes. Prior to joining Riedel, he held several finance leadership roles at Deutsche Telekom AG, where he worked in various controlling and transformation functions since 2008.

I am very grateful for the trust that Thomas and Frank have placed in me, said Engroff. I take on this responsibility with humility, supported by my outstanding team, which has been with me along the way, and by many great colleagues across the organization. Looking ahead, I am excited to continue shaping Riedel's development while ensuring we support its growth in a sustainable and resilient way.

Eischet added: Riedel's success has always been a team effort. I am proud of what we have achieved together over the past years and grateful to have been part of this journey. With Marc taking on the CFO role, we are strengthening our operational foundation even further. I look forward to focusing more on the broader development of the Riedel Group and driving the next phase of our growth.
