We are pleased to announce that, effective 15th June 2026, Bigler International AG will become Retis Materials AG. As of this date, Bigler International AG will change its name to Retis Materials AG, the legal entity itself will remain unchanged, and all employees will remain with the company under its new name. The company’s office location will remain unchanged and will continue to operate from Basel, Switzerland.

The decision reflects the evolution of the company’s activities and positioning. While the legal entity, ownership structure, contractual relationships, registration numbers, VAT number, and banking details will remain unchanged, the new name provides a more suitable platform for the future development of the business.
