• Strategic investor continues the long-established site independently under the name Demmel GronTec GmbH
• 107 employees remain at the Wasserburg am Inn site
• Restructuring managing directors Markus Fauser and Johannes Chrocziel of Anchor and custodian Volker Böhm draw a very positive conclusion

Wasserburg am Inn, 26 October 2026. The insolvency proceedings in self-administration of GWSPA Produktion GmbH (formerly Wilhelm Gronbach GmbH) are nearing a successful conclusion. In a structured international investor process, the Demmel Group from Scheidegg in the Western Allgäu region was secured as a strong strategic investor for the Bavarian company. In future, the company will operate independently under the new name Demmel GronTec GmbH. Operational management remains with the current managing director Gerald Seidinger. The sale is still subject to closing conditions, which are expected to be met in the coming days.

Wasserburg site and 107 jobs secured

With the investor solution, the production site in Wasserburg am Inn will be preserved permanently. As part of the acquisition, 107 employees will transfer to the new Demmel GronTec GmbH. To make the company viable and economically sustainable, an adjustment of the workforce was unavoidable: 43 employees will move to a transfer company, where they can be employed for up to six months and will be supported in their search for new jobs. The Austrian subsidiaries had already been sold successfully to an investor earlier in the proceedings.

Restructuring managing directors Markus Fauser and Johannes Chrocziel of the law firm Anchor, who supported the self-administration proceedings operationally together with Dr. David Blum and Alina Wallentin, are very pleased with the outcome. According to Markus Fauser (quote rendered in substance), the rescue of the site has created a sustainable perspective under the roof of a strong partner; he thanked all parties involved, in particular the employees as well as customers, suppliers and business partners who stood by the company during this demanding phase.

Long history at the Wasserburg site

The company was founded in 1964 in Wasserburg am Inn by Dipl.-Ing. Wilhelm Gronbach and specialises in ventilation technology, surface finishing, equipment construction and kinematics. As a full-service supplier and strategic supplier, the Wasserburg site manufactures high-quality components for well-known global brands in the household appliance industry as well as for partners in the automotive and medical technology sectors. A marked economic slowdown since the end of 2022, pronounced consumer restraint in kitchen furniture and household appliances, and massive cost increases in procurement and personnel had put considerable strain on the company. It therefore filed for insolvency proceedings in self-administration at the Rosenheim local court in April 2026, which were opened as planned on 1 July 2026.

Strategic investor Demmel taps potential in the non-automotive sector

The Demmel Group, an established medium-sized family business headquartered in Scheidegg, is taking over the production site. The group, whose parent company is Demmel AG, looks back on a history of more than 130 years that began as a sign factory. Today, with 1,200 employees at sites in Germany, Switzerland, Italy, China, Singapore and the USA, the group manufactures decorative trim parts, decorative surfaces, operating systems, electronics and mobile power supply systems, generating worldwide sales of EUR 240 million. The investor brings its own orders to the site, which will increase capacity utilisation. According to Sabrina Hirniak, CFO of Demmel AG/Demmel Group (quote rendered in substance), the acquisition strengthens the group's strategic diversification into the non-automotive sector and the site's technical know-how opens up new business areas and customer groups beyond the automotive industry.

Strong teamwork and stable continuation of operations

Markus Fauser stated in substance that self-administration once again proved its worth: rapid stabilisation of operations and restructuring measures made a tailored solution possible in the investor process. Volker Böhm of the law firm Schultze & Braun, who acted as custodian, also drew a positive conclusion: the acquisition by a strategic investor preserves the site and numerous jobs and is a very good result for creditors (quote rendered in substance).

Production in Wasserburg continued in full and stably throughout the self-administration proceedings. The M&A process managed by PLUTA Management GmbH under the direction of Ludwig Stern, the legal advice provided by a team led by Dr. Hendrik Boss and Julia Siedhoff (Taylor Wessing) and the business support by Lars Steinhagen and Bernd Grupp (allea consult) dovetailed seamlessly. Managing director Gerald Seidinger said in substance that maintaining operations without restrictions was the foundation for the successful sale and that the company looks forward to starting out as Demmel GronTec GmbH with additional orders from its new partner.
