Cooling and heating technology specialist Refitem Finland Oy and heating network specialist Putkiteho Oy are, with the support of Korona Invest, forming a new player in the energy and building services market.
Refitem Finland Oy and Putkiteho Oy have agreed on an ownership arrangement with the Finnish private equity firm Korona Invest, through which a fund managed by Korona Invest will acquire a majority stake in both companies, forming a new group in the energy and building services sector. The key personnel of the acquired companies will continue in their executive roles and remain significant owners. As a result of the transaction, the new group will be able to serve its customers even more comprehensively across cooling and heating technology and related services.
“Bringing Refitem and Putkiteho under the same umbrella, together with Korona Invest joining as an investor, enables the next phase of growth. The companies’ operations and core expertise complement each other and create added value for our customers,” says the Group CEO and founder of Refitem, Eero Timonen.
Korona Invest, a Finnish private equity investor focused on funding and developing growth-driven small and medium-sized companies, becomes the majority owner of the new group. With strong expertise in supporting entrepreneur-led businesses across service sectors, Korona Invest will help the companies accelerate into their next growth
stage and execute their growth strategy with long-term sector experience and a solution-oriented approach.
“Both companies’ deep specialist expertise and the founders’ strong growth ambition provide an excellent foundation for building a leading entrepreneur-driven energy and building services company. We want to bring our experience and an ownership approach focused on driving profitable growth to support the key personnel in scaling the business,” says Korona Invest’s CEO, Juho Mäkiaho.
