CDCL Groupe SA, Becolux SA and Teseos Luxembourg SA (a subsidiary of the Encevo Group) this week announced a significant change in the shareholding structure of All In One Technologies (AIO).

Effective as of Monday 24 November 2025, Teseos has acquired a one-third stake (33.33%) in AIO, alongside CDCL and Becolux, which each also hold a one-third stake.

AIO, a recognised player in innovative facility management, technical maintenance, energy performance and digital building services, now benefits from a three-way shareholding structure. This new configuration reportedly reflects the shared commitment of the three partners to strengthen an integrated approach encompassing the construction, operation and energy optimisation of infrastructure.

According to the partners, Teseos' investment sends a strong signal: this is not an isolated financial transaction, but a strategic consolidation aimed at building a more robust, coherent entity, fully capable of meeting the technological and energy challenges of the coming years.

The three shareholders said they share the conviction that a strengthened partnership will enable the development of comprehensive, sustainable and innovative solutions for higher-performing infrastructure, optimised maintenance and an improved end-user experience.

By combining their complementary expertise, CDCL, Becolux and Teseos aim to:

  • offer a complete value chain, from construction to operation;
  • accelerate the development of innovations in smart buildings;
  • improve the energy and operational performance of buildings;
  • provide a stable, attractive and opportunity-rich environment for AIO's teams.

They added that this partnership aims to ensure sustainable growth, enhance service quality and jointly prepare the infrastructure of tomorrow.
