(Sharecast News) - Porvair said on Tuesday that trading in the first four months of 2026 was in line with expectations, supported by steady demand across its diversified end markets, while maintaining its full-year outlook.

The London-listed group reported constant currency revenue growth of 5% for the period ended 31 March, with performance reflecting mixed conditions across its divisions.

Aerospace order books remained strong, although delivery timing continued to be influenced by customer scheduling, while nuclear demand had carried over from the second half of 2025.

Petrochemical sales were lower against a strong comparative period, with European market conditions expected to remain subdued through 2026.

In the laboratory division, life sciences consumables demand remained steady and environmental instrument sales were in line with the prior year, with new product introductions progressing as planned.

Within Metal Melt Quality, demand for aluminium and superalloys remained firm, although automotive, truck and agriculture markets were softer.

Porvair said progress continued on its £5.5m aluminium cast house manufacturing line in Hendersonville, US, which remained on track for commissioning in the first half of 2026.

The integration of German filtration business Drache, acquired in January, was also proceeding well, with trading in line with the pre-acquisition investment case.

The group noted that it was monitoring geopolitical developments in the Middle East, particularly in relation to macroeconomic uncertainty and rising input costs.

However, it said its decentralised structure and localised manufacturing footprint provided flexibility in managing volatility.

The board said its expectations for full-year performance remained unchanged, underpinned by a diversified customer base, recurring revenue streams and operational discipline.

It added that an increased focus on mergers and acquisitions identified a number of potential opportunities currently under evaluation.

Porvair said it expected to report interim results for the six months to 31 May on 29 June and would host a capital markets event in London on 15 October.

At 1435 BST, shares in Porvair were up 2.81% at 742.32p.
