Intera Partners invests in Engineering Seppo Rantala Oy


Insinööritoimisto Seppo Rantala Oy gains additional resources to support growth, as Intera Partners invests in the company. The company will become part of Infrak Group, which specialises in demanding infrastructure construction and currently comprises Fin-Seula Oy and Kesälahden Maansiirto Oy. The company’s CEO and main owner, Sami Rantala, will continue with the company and also becomes a shareholder in Infrak Group. The Group’s pro-forma sales amounted to over 140 million euros in 2013.

”Insinööritoimisto Seppo Rantala Oy is one of the leading players in Finland in demanding bridge construction projects and it has a good reputation among its customers and in the sector. We are very pleased with the company joining Infrak Group, as it will complement our existing offering particularly well and also further strengthens our bridge construction capabilities,” says Janne Näränen, Partner at Intera.

“A new significant player is emerging in the Finnish infrastructure construction market. We decided to join Infrak Group partly because we are familiar with the other Group companies and they have proven to be excellent partners in previous projects. This step will also enable the execution of even larger and more diverse projects. Furthermore, this is an excellent outcome for the continuity of the company and its employees,” comments Sami Rantala, CEO of Insinööritoimisto Seppo Rantala Oy.

The transaction is expected to be completed by the end of September and it will not have an impact on the business or the employees of the company.
