Munich, May 26, 2026 – WTS, an international full-service provider of tax consulting and complementary financial advisory services, advised dormakaba International Holding GmbH on its acquisition of AirSphere GmbH—a software provider of automated passenger handling and aviation IT solutions for airports. The scope of the advisory services included financial and tax due diligence.

Airsphere is a Germany-based software company specializing in automated passenger handling at airports. The company offers software solutions for self-service and e-gate-based passenger processes, biometric passenger processing, and mobile applications designed to optimize the travel experience. With solutions at over 250 airports worldwide, more than 8,000 e-gates in operation, and additional digital check-in points, as well as over 1 billion passengers processed annually via Airsphere solutions, the company ranks among the leading providers in the field of aviation IT and passenger automation.

With the acquisition of AirSphere, dormakaba is entering the rapidly growing market for digital passenger services at airports. The transaction complements dormakaba’s existing portfolio of access solutions and security systems with innovative aviation IT technologies and unlocks synergies throughout the entire passenger journey at the airport. Airsphere will continue to operate independently in the market and serve both dormakaba’s customers and its own existing customer base.
