Katja Ziegler takes over sole management of ESG

Katja Ziegler, Chief Financial Officer of ESG, will take over the sole management of ESG Elektroniksystem- und Logistik-GmbH from 1 June 2024 until further notice. This also involves the transitional management of the ESG division within the HENSOLDT Group. Managing Director Christoph Otten will be leaving the company at his own request at the end of May to pursue new opportunities. 
"We regret Christoph Otten's decision, as we are losing a valuable manager in him. He has led ESG on a sustainable growth path in recent years and successfully supported the takeover by HENSOLDT. On behalf of the entire Management Board, I wish Mr Otten all the best for his future career," said HENSOLDT CEO Oliver Dörre. "We are delighted that Katja Ziegler is taking on this additional responsibility. In recent months, Katja has provided important impetus for the integration of ESG into the HENSOLDT Group and we look forward to working with her on the Executive Committee," Dörre continued. 

Sensor solutions provider HENSOLDT completed the acquisition of ESG in April 2024. By combining the highly complementary capabilities of HENSOLDT and ESG, the company will further strengthen its position as a leading European provider of seamlessly integrated solutions.
