As of October 1, 2025, Rosenberger Hochfrequenztechnik GmbH & Co. KG has appointed Josef Rottenaicher as the new Chief Financial Officer (CFO) of the Rosenberger Group. He succeeds Franz Praxenthaler, who has retired after 48 years with the company. The Executive Board and Board of Directors would like to thank Franz Praxenthaler for his many years of service and welcome Josef Rottenaicher to his new role - along with a clear commitment to continuity and trust in the company's management.
Experience and new impulses
Josef Rottenaicher brings extensive experience from his time at BayernLB, where he worked in Corporate & Investment Banking, among other things. He joined Rosenberger in 2016 and has since played a key role in strategic initiatives and structural projects. Most recently, Rottenaicher was responsible for Group Finance & Controlling.
He is an experienced financial strategist who will assume responsibility for the financial management and further development of the Rosenberger Group. His expertise and deep understanding of the corporate structure form the basis for a future-oriented financial strategy that focuses equally on stability and growth.
Tribute to Franz Praxenthaler
After a total of 48 years of service, Franz Praxenthaler was given a festive send-off on September 25 in the company's own restaurant. Well over 100 guests, including colleagues, business partners and representatives of the owner family, attended the event.
In his speech, Hans Rosenberger particularly emphasized Praxenthaler's foresight, reliability and his contribution to the company's exceptional development. The management, colleagues and the works council also thanked him for his many years of service. At the end, Franz Praxenthaler bid a visibly moved and grateful farewell.
With the appointment of Josef Rottenaicher as CFO, Rosenberger is focusing on continuity and new impetus at the same time.
"I see the finance organization as an active shaper of corporate strategy - with a focus on transparency, efficiency and global management," emphasizes Rottenaicher.
His aim is for the finance departments not only to accompany, but also to make a measurable contribution to achieving the corporate vision.
