Pinnacle Technology founder and Chief Executive Alan Bonner is to step down.
The announcement came in a trading statement as the company reported a fall in revenues for the year to the end of September.
Revenues of approximately £10.1m were down on last year's £12.7m.
Following the announcement of Interim Results to 30th March 2013, the board conducted a root and branch review of the group and took actions to reduce ongoing costs. As a result the group is now trading close to EBITDA breakeven on a monthly basis, however Bonner decided that after 15 years the time is right to seek a successor.
"I am hopeful that we can soon appoint a new Chief Executive who will help us achieve our objectives, and I look forward to ensuring a smooth transition in the best interests of our customers, staff and all other stakeholders," he said.
This financial result relates in large part to a poor performance from the previous acquisition of RMS IT Security, and the lack of any major UK high-profile events in the period (compared to the Queen's Diamond Jubilee celebrations and the London Olympic Games contracts, which were delivered in the year ended 30 September 2012).
In consequence, both EBITDA and Pre-tax loss when finalised, will show a significant deterioration on the figures for the previous year (2012 adjusted EBITDA £284,554; 2012 Loss before tax (£1,115,558).
