Internet equipment maker NetComm has delivered a net loss of $1.2 million despite a 22 per cent jump in full-year revenue. Management blamed the red ink on a one-off write-down of inventory, which it said had an adverse impact of $2.2 million on its bottom line. An exclusive deal to supply next-generation wireless routers to the NBN could generate up to $200 million in the three years to June 2015.
