The Group performed in line with expectations in the first nine months of the financial year, delivering constantcurrency revenue growth of 14%, 5% organic constant currency. This reflects the revenue contribution from Drache, acquired in January 2026, and the resilience of Porvair's diversified portfolio amid varied conditionsacross the Group's end markets. Aerospace & Industrial Aerospace order books remain strong, noting that the timing of delivery can be affected by changes in customerscheduling. Industrial markets have remained mixed. Robust nuclear demand has continued throughout theperiod. Petrochemical sales, which can be lumpy, have remained subdued as expected, and market conditions in Europe are expected to remain challenging for the balance of 2026 and into 2027.

For the year ended December 2025, GV Filtri’srevenue was approximately €5m and the company employs around 30 people. Laboratory Life sciences continued to grow, with consistent demand for consumables, while laboratory instruments suggest some moderation.

New product introductions across life sciences and environmental are progressing as planned. Metal Melt Quality Aluminium and superalloys demand remains robust, whilst the auto and agriculture end-markets, which representa smaller part of the Group, remain subdued.
