"In its core broadcast market Vislink Communication Systems has seen a reduction in spend from broadcasters as they divert budgets from building infrastructure to investing in content. A technology shift to IP infrastructures has also delayed key buying decisions.
"With this background and with a desire to increase the efficiency of VCS and ensure that we build a cash generative sustainable and profitable business we have taken a number of decisive actions as part of our business improvement plan, including the move of the VCS finance function to Head Office leading to improved cash collection.
"We will continue to re-evaluate implementation of the business plan as trading progresses into H2."
