"This consolidation, whilst impacting on gross margin in the short-term, is yet to be reflected in the company's sales to a positive degree, but presents the company with a good opportunity to continue to grow its market share in the medium to longer term," said chief executive Terry Smart.
Dick Smith Electronics, with about A$1.5 billion in annual sales, plans to close up to 100 stores before February 2014.
And Queensland-based WOW Sight and Sound, which operated 15 stores, and reported A$250 million in sales last year, went into receivership in February. JB Hi-Fi said it is negotiating on leases for two former WOW sites.
The company expects to continue discounting into the June quarter.
" JB Hi-Fi will react aggressively to maintain our market leadership," Smart said.
