Trading Update

Porvair, the specialist filtration and environmental technologies group, today issues a trading update ahead of the publication of its interim results for the six months ended 31 May 2015 on Monday 29 June 2015.

The Group expects to report underlying revenue growth with demand at or ahead of expectations in most markets. Interim profits will be ahead of those reported in 2014. Net cash at 31 May 2015 will be £7m higher than at 31 May 2014. As previously reported, underlying revenues exclude proceeds from the large contracts recorded in 2014.

The large projects continue to progress smoothly with further work in the pipeline. As expected, revenues from the large projects will be lower than the prior year.

Investments have been made to complete and open new plants in the UK and USA. The expansion of the China facility continues on schedule and to budget. Order books for the second half are healthy.

An analyst briefing will be held at 9.30 a.m. at Buchanan, 107 Cheapside, London, EC2V 6DN on the day of the interim results, Monday 29 June 2015.
