Etherstack plc provided revenue guidance for the fiscal year of 2017 and first half of 2018. The company expects the fiscal year 2017 revenue to be between USD 4.1 million - USD 4.3 million, with first half of 2018 revenues being unusually higher than previous first half periods due to the timing of revenue shifting from first half of fiscal year 2017 to first half of fiscal year 2018.
