AGM Trading Update

Group trading remains in line with our full year expectations. Integration of Drache acquisition remains on track.

Porvair plc ("Porvair" or the "Group"), the specialist filtration, laboratory and environmental technology group, will make the following trading statement at its Annual General Meeting to be held at 11.00 am today:

Four-month trading summary for the period to 31 March 2026

The Group has performed in line with expectations in the first four months of the year, delivering constant currency revenue growth of 5%. This performance reflects the qualities of Porvair's diversified portfolio, as market conditions remain varied across the Group's end markets.

Aerospace & Industrial

Aerospace order books remain strong, noting that the timing of delivery can be affected by changes in customer scheduling. Robust nuclear demand in the second half of 2025 has continued into the current year. Petrochemical sales, which can be lumpy, are lower compared with a strong prior period, and conditions in the European petrochemical market are expected to remain subdued throughout 2026.

Laboratory

Within life sciences, consumables order patterns remain steady, while environmental demand for instruments is in line with the prior year. New product introductions across life sciences and environmental are progressing as planned.

Metal Melt Quality

Aluminium and superalloys demand remains firm, whilst the auto, truck and agriculture end-markets, which represent a smaller part of the Group, remain subdued. There has been good progress with the new £5.5m aluminium cast house manufacturing line in Hendersonville, US, which remains on track for commissioning in the first half of 2026. The integration of Drache, acquired on 12 January 2026, is progressing well after three months with the Group and trading is consistent with the pre-acquisition investment case.

Outlook

The Board is closely monitoring the situation in the Middle East, in terms of both macro uncertainty and rising input prices. The Group's manufacturing footprint mainly serves local customers, and its decentralised management structure provides flexibility, agility and resilience in navigating volatile trading conditions, enabling key commercial decisions to be made closer to customers and suppliers.

The Board's expectations of the Group's full year performance remain unchanged, supported by a diversified customer base, strong recurring revenue streams and disciplined operational management. An increased focus on identifying M&A targets has surfaced some interesting prospects which are currently being evaluated. The Board sees no change in the Group's long-term strategic outlook or global growth drivers.

Capital Markets Event

Further to the full year results announcement, Porvair will host a Capital Markets Event in London on Thursday, 15 October 2026. Further details will be provided in due course.

Notice of results

The Group will announce its interim results for the six months ending 31 May 2026 on Monday 29 June 2026.
