Deal done: ADT

DEAL DONE | Aeternus acted as the advisor of ADT in sale to international PE party Triton

With this acquisition, Unident, Hofmeester and ADT form the European leader in Dental Distribution & Services.

The largest supplier of dental supplies within the Benelux, ADT has been acquired by Swedish investment firm Triton. The acquisition is part of the merger of three companies Unident (Sweden), Hofmeester (Netherlands) and ADT (Netherlands). Together they form the new European leader in this sector.

Led by Triton, the new group achieves annual sales of more than EUR 160 million with activity in 9 countries serving more than 20,000 clinics. The group formation enables the companies to achieve various synergies within the product range and create new propositions in different markets.

The individual companies will retain their own brand names and management teams.


‘Aeternus assisted the shareholders of Dutch American Dental Trading in the sale of their company to Swedish strategic private equity party Triton. The buyer is already active in the Netherlands through holdings in Unica and Bergman Clinics. Triton also owns consumables trading house Unident, which is particularly active in the Nordics. The acquisition of both ADT and Hofmeester establishes the group as the European market leader in dental consumables. A wonderful strategic deal to be involved in as M&A advisors.’

Peter Joosten, Managing Partner Aeternus


‘After a second round of optimization of our advanced logistics center, ADT was ready to realize further international growth. To take a look beyond the familiar, we contacted M&A advisor Aeternus who, in her search for various alternatives, came up with potential parties that we had not yet set our sights on ourselves. We were excited about the optimal opportunities for synergy offered by the various parties they introduced. After a careful selection process, directed by Aeternus’ M&A team (Peter Joosten & Niek Jacobs), an agreement was finally reached with Triton and through them with Unident and Hofmeester. As a team with a solid footprint in Northern and Western Europe, we are ready for a new phase of our company.’

Pieter van Lieshout, CEO ADT

The shareholders of ADT were assisted in this process by Peter Joosten and Niek Jacobs of Aeternus. The transaction came about in close cooperation with Mickey Engel and Ruben Schulpen of AKD.

We wish ADT, Unident, Hofmeester and Triton every success in further developing this leading partnership.
