IQE plc reiterated earnings guidance for the year 2019. Three key factors affect IQE's revenue outlook for 2019 are: Continued uncertainty related to the geo-political landscape, the effects on global technology markets and, in particular,the confidence for supply chains to rebuild inventory; The market for smartphone handsets in the second half of 2019; The speed of formation of new Asian supply chains, the associated product qualifications and volumes of initial orders. Balancing these factors, full year revenue guidance of GBP 140 million to GBP 160 million is reiterated. Second half revenues are expected to represent between 52% and 58% of full year revenues. IQE expects to remain profitable in 2019 but with adjusted operating profit margin significantly below the original fiscal year 2019 guidance of over 10%, is reiterated.
