Vestum strengthens its position in moisture protection and water and wastewater systems through acquisition of two niche companies with total sales of SEK 218 million

Vestum AB (publ) (”Vestum”) has – through Vestum Sweden AB – agreed to acquire 100% of the shares in Isodrän AB (”Isodrän”) and MDT Markvaruhuset AB (“MDT”). The companies will be included in Vestum’s Infrastructure segment. In the fiscal year of 2021, Isodrän and MDT generated aggregated sales of SEK 218 million. The purchase price will be paid through payment in cash and issuance of shares in Vestum, resulting in a dilution of approximately 1.9%.

Comments from Conny Ryk, CEO of Vestum:

Today, I am very happy to be able to present two incredible companies in Isodrän and MDT! Both companies are attractively positioned on the growing moisture protection, which is characterised by low cyclicality. Isodrän has been on the market for 30 years and has a strong brand in the moisture protection industry. Together with our portfolio company Pordrän, we will continue to develop the operations, both in Sweden and internationally. MDT is a specialised company with extensive knowledge in water and wastewater systems, moisture protection and foundations, and with the potential to roll out the concept to additional regions. In summary, Vestum is complemented by two niche companies with a distinct focus on the infrastructure and ROT (repair, conversion and extension) industries, says Conny Ryk, CEO of Vestum.
