LightwaveRF Plc provided earnings guidance for the six months ended 31 March 2018. The company anticipates that first half revenue will be broadly in line with the prior year and gross margin will have increased to over 40%. The completion of the last stage of the £5.25 million fundraising in December 2017 marked the start of the process to significantly scale the business. As anticipated, the accelerated investment in R&D, marketing and sales will have significantly increased administrative expenses over the same period last year. As a result, the company expects losses before tax for the six months ended 31 March 2018 to be markedly higher than those reported in the first half last year.
