Trading Update

We are pleased to report that our business has continued to perform well, with total revenues in the first 4 months of the year up 21% compared with the same period in 2022. Our core Clinical business grew strongly with revenues up 28% compared with the same period in 2022. EMEA has continued to experience strong growth, and our Asia markets have also improved significantly. In the USA, our relatively new distributor partners are starting to make an increasing contribution to revenues in the region, which were up 16% year to date compared with 2022.

Gross margins continued to be robust, which together with the lower overheads as we exited 2022 meant that adjusted EBITDA for the first four months of the year was well ahead of management expectations.

The unaudited cash balance at 30 April 2023 was £22.3m (31 December 2022: £19.4m). Returns claims amounting to £1.1m relating to the discontinued business that were noted at the time of the preliminary results were settled in April.

Ian Johnson, NIOX's Executive Chairman, said: "I am pleased to report a continuing strong trading performance in the year to date, reflecting the successful execution of our strategy. The effect of the growth in revenues, robust margins and the lower level of overheads means that adjusted EBITDA for the full year is now likely to be significantly higher than management expectations at the start of the year.

The Board believes that the cash generation and resources of the Group are now at a level where it is appropriate to commence the payment of a dividend. Further details of the timing and quantum of an initial dividend payment will be announced in due course.

I look forward to updating shareholders again on our further progress and plans at the time of the H1 trading update in July."
