License Delays and Trading Update

Tristel plc, the manufacturer of infection control, contamination control and hygiene products, announces that as a consequence of delays in receipt of the licence to sell its Stella tray system in China and the delay in securing inclusion of its Wipes System on Germany's VAH listing, a substantial portion of revenues originally anticipated to fall in its current financial year will now be deferred to the financial year commencing 1 July 2011. The Company's planned expansion into the Pharmaceutical and Personal Care market with its "Crystel" range of disinfectants and cleaning products has also had a slower start than anticipated.

Whilst the Company is confident that the license delays referred to above will be successfully concluded, it is unlikely that Germany and China will make the positive contribution to the current year's result originally anticipated. Therefore, the Company now anticipates results for the second half will be at least break-even (pre-IFRS 2 charge) delivering a full year pre-tax profit of no less than £433,000.

In line with its expansion plan, the Company has continued to invest in sales and manufacturing infrastructure and the second half result is, therefore, bearing a much enlarged cost base. The Company remains debt free and will continue with its expansion plan as detailed in the interim results. Significant growth is anticipated in 2012 and beyond.
