HIMA Group bids farewell to Peter Sieber as he retires and

realigns strategic marketing

UAE, Dubai, December 17, 2025 – Peter Sieber will retire on December 31, 2025, after

twelve years with HIMA Group. He will continue to support the company in an advisory
capacity.

During his tenure at HIMA, Sieber made significant contributions to the company's success.

As a recognized expert in functional safety, he played a key role in expanding HIMA's
solution portfolio and advancing the digitalization of functional safety under the motto
#safetygoesdigital—delivering solutions that create tangible value for customers. Through his

long-standing involvement in international standardization committees, he also contributed
substantially to the global development of functional safety and OT security.

Most recently, Sieber led the Strategic Marketing division. Previously, he was responsible for

international sales, norms and standards, and the China region. His key achievements
include establishing HIMA’s presence in China and expanding local business operations.

"Peter Sieber has successfully driven the digitalization of functional safety with his creative
drive and wealth of ideas, both nationally and internationally. His personal dedication in
establishing HIMA China and fostering partnerships in the region is particularly noteworthy,"

said Jörg de la Motte, CEO of HIMA Group.

As part of the company’s succession plan, Sergej Arent will assume overall responsibility for

the Customer Solutions Center (CSC), which will include Applications, the HIMA Academy,
HIMA Consulting, and the newly established Solutions Management for Turbo-Machinery
Control (TMC), Safety Lifecycle Digitalization (SLD), and Pipeline Leak Detection Systems

(LDS). Ivo Hanspach will take over HIMA Group’s activities in norms and standards, in
addition to his role as Head of Product Management.

With this realignment, HIMA Group is strengthening its position as an independent

technology and solutions partner and a pioneer in the digitalization of functional safety.
The company thanks Sieber for his many years of service and wishes him all the best for the

next chapter of his life.
