Trading Update & Notice of Results

Arcontech (AIM: ARC), the provider of products and services for real-time financial market data processing and trading, announces that for the year ended 30 June 2023 turnover is expected to be in line with market expectations and adjusted EBITDA and adjusted profit before tax is expected to be ahead of market expectations by approx. 31% and 49% respectively through a combination of lower than anticipated staff related costs arising from lower variable costs and delayed hires. These are expected to be once off savings in the year to 30 June 2023. Expectations for the current financial year therefore remain unchanged.

Financial expectations noted above are preliminary and subject to year-end financial close and audit review processes.

Notice of Results

The Company’s results for the 12 months ended 30 June 2023 are expected to be announced in early September 2023 and the Board look forward to updating shareholders with further details at that time.
