Dussmann to acquire Lynskey to become a full-service provider for mechanical building services and electrical engineering

Berlin/Dublin, July 3, 2025 – The international multi-service provider Dussmann acquires all shares in the multinational Irish headquartered specialist mechanical engineering company, Lynskey Engineering. Lynskey Engineering Group, which has around 120 direct, highly specialized employees and an annual revenue of 
€60 million, will continue its course of growth within the Dussmann Technical Solutions division. The parties have agreed to keep the purchase price confidential.

The planned acquisition strengthens the Dussmann Technical Solutions division, which was founded in May 2019 and has acquired several other technical services companies, including Irish STS Group, the multinational specialist electrical engineering company. Dussmann Technical Solutions bundles technical expertise across the entire life cycle of facilities and buildings projects: from design, technical planning, installation and commissioning to technical maintenance, repair and operations all from a single source. The acquisition of Lynskey adds to the existing portfolio in-house capabilities and brings for the first time the ability to self-perform specialist mechanical services. 

“The acquisition of Lynskey directly contributes to our ‘Road to 2030’ strategy. An important goal here is to establish and expand our range of engineering services for clients with complex technical demands and mission critical systems in the industrial, energy and data centre sectors,” says Wolf-Dieter Adlhoch, CEO of the Dussmann Group.

Lynskey has successfully completed specialist technical projects for blue chip clients in the data centre, pharmaceutical, retail, commercial and energy sectors. The Group provides specialist mechanical design, engineering, installation and commissioning services for its clients across Europe. Lynskey also provides technical maintenance services for clients in Ireland.

Stephan Possekel, Managing Director at Dussmann Technical Solutions, commented on the planned acquisition: "We already have worked with Lynskey on delivery of several successful projects in the data centre sector. Lynskey's portfolio of mechanical services seamlessly complements STS's electrical engineering services”. Chief Technical Officer and Managing Director Oliver Finckh adds: “The acquisition of Lynskey will enable us to offer both main trades – mechanical as well as electrical services on complex large-scale projects, thus being a single source provider of mechanical, electrical, and plumbing services.” 

The combined entity can offer its clients an even more comprehensive and powerful service portfolio, especially for clients in the pharmaceutical sector, an important industry Dussmann successfully operates in. As part of the “Road to 2030” strategy, Dussmann Group is focusing on megatrends and implementing innovations to increase energy efficiency and improve the carbon footprint. Its services make a significant contribution to the development of sustainable and future-oriented solutions that meet the requirements of Dussmann Groups customers.

The existing employees of Lynskey will be unaffected by the transaction. The senior management team of Lynskey, including its Managing Director Sean McElligott, will remain in their existing roles post-acquisition.

Sean McElligott sees great opportunity in joining Dussmann: “This provides an excellent opportunity for both our clients and employees. Our clients will continue to enjoy the same level of superior service provided by our team, delivering complex technical mechanical projects within time and on budget, and will post-acquisition also benefit from the increased scale and service capability we can offer as part of a ca. €3.3 bn turnover group. Similarly, our employees will find increased opportunities provided by the ambition and support of Dussmann to grow our business further.  Myself and the entire senior management team are very excited to become part of the Dussmann Group and are looking forward to our new future together.”

Lynskey was advised by Anglesea Corporate Finance. The acquisition is subject to approval by the Irish antitrust authorities and is expected to be completed in Q3 2025.
