In a brief trading update, NetDimensions (AIM: NETD, OTCQX: NETDY) has said that FY15 trading was in line with expectations. It also says that the operating cost base actually fell over the year and hence the adjusted EBITDA loss will be better than current market expectations. Despite a significant de-rating in the shares of its US-quoted human capital management software peers over the last two years, these companies continue to trade on punchy EV/sales ratios. Hence we continue to believe there is significant upside potential in NetDimensions' shares.
