Nine Month Trading Update

Porvair plc, the specialist filtration, laboratory and environmental technology group, announces the following trading update for the nine months ended 31 August 2025.

The Group has continued to trade satisfactorily in the third quarter. Market trends remain consistent with those set out at the half year. We continue to monitor the macro-economic uncertainty and note that the Group's manufacturing footprint mainly serves local customers.

The Group's fundamental demand drivers have not changed and Porvair remains well positioned to take advantage of tightening environmental regulation; the growth of analytical science; the need for clean water; the development of carbon-efficient transportation; the replacement of plastic and steel by aluminium; and the drive for manufacturing process quality and efficiency.
