This agreement, originally set to expire in 2027, has now been extended by three additional years, covering deliveries potentially through the end of 2030.

A strengthened partnership to meet growing global demand

This extension represents a significant contribution to the collaboration between the two companies.

Within the scope of this extension, Theon will exercise its options for 2027 and 2028 before the end of the year, converting them into firm committed orders. It solidifies Exosens' role as a preferred supplier to European Armed Forces and global markets.
