Infection prevention and contamination control products company Tristel is on track for a further growth in profits.

In a trading update ahead of its annual general meeting, taking place today at the company’s headquarters near Newmarket, Tristel said its performance remained in line with management expectations.

Paul Swinney, chief executive, said: “We are delighted that once again we expect to report period-on-period profit growth for the six months to December 31, 2017.

“We expect unaudited pre-tax profit for the first half to be no less than £1.9m, compared to £1.7m for the same period last year. Both figures are before share-based payments. Tristel continues to perform in line with management’s expectations and our strategic financial goals.”

Mr Swinney also said that additional data requested by the US Environmental Protection Agency as part of the company’s bid to under the American market had been submitted by the agreed deadline of November 15.

“The North American regulatory programme continues to progress in line with our project plan,” he added.

Tristel, which is based on the Lynx Business Park at Snailwell, is due to publish its interim results on February 20.

In October, the company announced pre-tax profits of £3.966m for the 12 months to June 30, compared with £2.593m the previous year, on turnover 18.5% higher at £20.273m.
