KSBR (Keski-Suomen Betonirakenne Oy) and GRK Infra Oyj have signed a share purchase agreement on 18 May 2026, under which GRK will acquire KSBR and its subsidiaries.

The transaction is part of both companies’ strategies to pursue profitable growth and to strengthen their positions in projects related to the green transition and industrial construction.

– KSBR has grown from a small concrete company into a major player operating across four business areas. Our principal owners have carried out long-term and determined work over more than 20 years to develop and grow the company. We can now take pride in the results of this high-quality work and in the fact that we are gaining broader shoulders for building the future, says Marko Leppänen, CEO of KSBR.

According to Leppänen, the two companies are guided by very similar values and operating cultures.

– Both of us invest heavily in quality, expertise and people. Our value bases also align in the way we operate and get things done. We clearly recognise many shared sources of pride and common objectives.

The goal of both companies is clear: to offer customers a broader range of services, stronger expertise and better capabilities to deliver demanding projects in the future.

KSBR complements GRK’s expertise

– KSBR is a strategically very strong addition for us. It complements our expertise, strengthens our position in selected segments, and serves as an important entry into private-sector sales and new customer relationships, says Mika Mäenpää, CEO of GRK.

According to Mäenpää, the acquisition will also significantly enhance GRK’s ability to participate in larger and more demanding project entities, particularly in critical infrastructure as well as energy and data centre projects.

– KSBR’s exceptionally strong expertise, for example in demanding concrete structures, directly supports our ability to deliver even more challenging projects. The transaction will also generate clear synergies in both sales and operational activities, supporting our profitable growth and long-term value creation.

Operations continue as normal

KSBR and GRK will continue to operate under their own names and familiar brand identities. Daily operations and ongoing projects in both companies will continue as normal.

Completion of the transaction is subject to regulatory approvals. Provided that the conditions for completion are met, the transaction is expected to be completed on or around 1 July 2026.
