Assemblin Electrical strengthens its position in the Stockholm region by acquiring M3 Installation AB

In the beginning of July, Assemblin Electrical acquired electrical installation company M3 Installation AB (“M3 Installation”) with operations in Stockholm, annual sales of about SEK 35 million and 21 employees.

M3 Installation AB began operating in 2004 and is now a stable contracting and services company with operations in the Greater Stockholm area. The company’s head office is located in Täby, north of Stockholm. The company’s assignments are distributed relatively evenly between contracting and service assignments, mainly involving commercial properties and renovations of shops and shopping centres. Major customers include Arcona, Vasakronan and the Willys chain of supermarkets.

“M3 Installation has a well-established and well-managed organisation with skilled employees and an impressively high proportion of satisfied, loyal customers. We are very pleased with this acquisition, which gives us a good foothold in the Stockholm area. Our shared ambition is to continue developing the business in close cooperation, to the benefit of employees and customers alike,” says Fredrik Allthin, President and Business Area Manager for Assemblin Electrical.

“To ensure the continued development of the operations and to accelerate our growth, we need an active owner to support our continued journey. We perceive Assemblin as a beneficial and responsive owner and look forward to working with them more,” says Mikael Ekstam, Branch Office Manager at M3 Installation, and Björn Ring, Project Manager at M3 Installation.
