Porvair plc ("Porvair" or the "Group"), the specialist filtration, laboratory and environmental technology group, announces that on 14 July 2023 it completed its acquisition of 100% of the issued share capital of two businesses, Ratiolab GmbH and Ratiolab Kft. (together "Ratiolab"), following receipt of Hungarian regulatory approval.

As previously announced, Ratiolab GmbH, located outside Frankfurt, sells a wide range of laboratory consumables in Europe and the Middle East. Ratiolab Kft., located close to Budapest, manufactures laboratory consumables in an 8,000m2 facility, the freehold of which is included in the acquisition. Ratiolab has annual external revenues of around €12 million. The transaction is expected to be earnings neutral (after acquisition costs) in 2023, and earnings enhancing thereafter.
