Rakon reported a net loss of $400,000 in its last financial year.
Robinson said delays in the roll-out of "radar related" European military contracts, which Rakon was due to supply componentry for, were the main reason for the downgrade.
"It's not a loss of business - it's just a delay," he said. "It's probably something to do with the austerity measures [in Europe]."
Robinson said around $2 million worth of military-related business had been delayed for two quarters.
Rakon was also having trouble securing materials for its smart wireless segment - where it supplies components for consumer products such as smartphones and tablet computers - and had been forced to delay delivery of orders to a number of customers, he said.
"They're just normal supply chain issues."
Robinson said margins for some consumer-related products were being affected by the strong New Zealand dollar, which hit a nine-month high of US84.41c against the greenback last week, as well as "competitive pressure".
Rakon is responding to the challenges it faces by shifting manufacturing from this country to lower-cost facilities in China and India.
The company said those actions would save $10 million a year and 70 per cent of the changes would be in place by April 1 next year.
Robinson said he was surprised by how far Rakon's share price had fallen yesterday.
"It's dropped a lot more than I expected it to."
