Underlying profit before tax dropped by 26.8% to £64.4m at Sports Direct for the 26 weeks to 28 October 2018.
Group revenue increased however by 4.5% to £1.79m at the Shirebrook-based business.
Mike Ashley, Chief Executive of Sports Direct International plc, said: “During the reporting period we acquired the trade and assets of House of Fraser and I would like to welcome my new colleagues to the Sports Direct Group.
“I have made my views clear that I believe the previous House of Fraser senior management team traded the business whilst it was insolvent for a long time, this means we have significant challenges ahead in turning House of Fraser around.
“However, I genuinely believe we have acquired a fantastic opportunity and with the efforts of Sports Direct and House of Fraser teams, and the support of the brands, local councils and landlords, we can turn House of Fraser into the Harrods of the High Street.
“Outside of the House of Fraser acquisition the Sports Direct Group has had another successful period reporting a 15.5% growth in underlying EBITDA to £180.3m. This is impressive in the context of the current struggles in the High Street and shows our elevation strategy continues to go from strength to strength.
“Excluding House of Fraser we anticipate we will be within our previously communicated underlying EBITDA growth range of 5-15% by year end, including House of Fraser we expect to be behind last year’s result.”
