  • Further acquisition opens up new market for security and alarm technology
  • Accelerated growth through expansion of the group of companies
  • Strategic positioning as a mechatronics group of companies with own products and component production and assembly

Schaan, Liechtenstein, 07th February 2023 – FMA Holding AG (“FMA Group”) announces the acquisition of NOX Systems AG (“NOX”), a leading developer and manufacturer in the field of security technology, with a focus on security and access control systems, headquartered in Vaduz, Liechtenstein. With this acquisition, FMA Group underlines its strong growth with another strategic purchase in a niche market. NOX adds to the Group outstanding development expertise in the field of security systems as well as deep mechatronic expertise and a strong international customer base. The company’s founder, Sven Sauter, will remain with the company in his current role as Managing Director.

NOX’s products are widely used to support access control, intrusion detection systems and video surveillance. Furthermore the products have an excellent reputation, especially with larger international customers, due to the flexibility, individuality and holistic offer. NOX is able to meet all the security needs of these customers. Customers include, for example, banks, museums and other buildings, that have particularly high security requirements.

“We are delighted about this promising merger,” explains Sven Sauter. “We have had trusting and valuable discussions over time, which have convinced me that we have found the right partner to further develop NOX. This step is a positive sign for our employees, customers, suppliers and other business partners. We are convinced that we can accelerate our growth with FMA Group as a strong partner. I look forward to actively shaping this path as Managing Director.”

Through the acquisition of NOX, the FMA Group is expanding its business model to include a strong product portfolio in the field of security technology. As a result, the FMA Group grows to three companies with a total of four production sites and approximately 120 employees, thus strengthening its position as a mechatronics group in the DACH region. NOX will remain as an operating unit under the management of Sven Sauter.

“The business model is complementary to FMA and allows a strategic further development from “manufacturing service provider of mechatronic assemblies” to “mechatronics group with own and third-party products” with a versatile engineering know-how,” says Managing Director of FMA, Erich Trinkler. “Due to the geographical proximity, we hope to mutually benefit from this corporate merger and increase joint growth.”
