Jean-Marie Laurent Josi, Managing Director of Cobepa said: “Together with management, we have been able to transform SGG into one of the leading players in the Benelux with a solid international platform. After 5 years of successful collaboration with management, we believe SGG is now ready for its next phase of development with a new shareholder and we are pleased that Astorg has agreed to continue that journey with management.”

Serge Krancenblum, CEO of SGG said: “I would like to thank Cobepa for its support in developing SGG over the last five years. On behalf of SGG’s management team and employees, we welcome Astorg as our new main shareholder. With Astorg’s support, we aim to accelerate SGG’s growth through the launch of new services and further expansion into new jurisdictions.”
