Porvair (LSE:PRV), the specialist filtration, laboratory and environmental technology group, said trading in the nine months to 31 August was in line with expectations, with constant currency revenue up 14%, or 5% on an organic basis.
The growth reflects the contribution from Drache, acquired in January, alongside resilience across Porvair's diversified end markets.
The Board now expects full-year trading to run slightly ahead of market expectations following the completion in September of the acquisition of GV Filtri Industriali, an Italian industrial filtration business with approximately €5m of revenue and around 30 employees for the year ended December 2025.
Within Aerospace & Industrial, order books remain strong and nuclear demand has stayed robust, though petrochemical sales have been subdued as expected, with European conditions seen staying challenging into 2027.
The Laboratory division saw continued growth in life sciences consumables, encouraging environmental testing demand, and a positive early contribution from Carekem, acquired two months ago.
In Metal Melt Quality, aluminium and superalloys demand remains robust while auto and agriculture markets stay subdued; the integration of Drache is progressing to plan and trading there remains slightly ahead of expectations.
Porvair will host a Capital Markets Event in London on the afternoon of Wednesday, 14 October.
News Intelligence what this means for the company
Porvair upgraded its full-year outlook to 'slightly ahead' of market expectations after completing the GV Filtri acquisition in September, building on 14% constant-currency revenue growth in the first nine months driven by the January Drache acquisition and 5% organic growth. The upgrade signals confidence that bolt-on M&A is integrating well and that diversified end-market exposure—particularly strength in aerospace, nuclear, and metal melt quality—is offsetting weakness in petrochemicals and auto/agriculture.
The upgrade is modest in scope ('slightly ahead') but reflects execution risk being retired: two acquisitions (Drache and GV Filtri) are now embedded in guidance, and management is signaling that integration is tracking to plan. However, the company flagged European petrochemical conditions staying 'challenging into 2027,' which caps upside in a material end market.
