"The funds raised will enable Ike to increase capacity to service new and targeted Ike customers, some of whom are the largest communications and electric utility infrastructure companies operating in North America," said chief executive Glenn Milnes.
Earlier this month, Ike announced one of the largest communications infrastructure companies in the US had standardised the ikeGPS platform for its 5G and fibre deployment.
Milnes said at the time the expected revenue from the new customer was "not yet defined".
In the year ended March, the company's revenue reached a record $9.8m, up around 23 per cent on the prior year, although the company still made a $5.6m loss.
Ike shares are on a trading halt, at 77 cents, until Thursday morning.
