Game chairman Peter Lewis said: “To date, our customers' spending patterns have remained relatively resilient considering the challenges in the wider economy. Our previous guidance is unchanged and the board remains confident of a successful outcome for the year.”
The retailer opened 183 stores in the year to date and will operate from 1,340 stores over the Christmas trading period. It added that the integration of its acquisition in the Czech Republic is “progressing well” and “trading is in line with expectations”.
Sector 'not immune' to downturn
Singer Capital Markets analyst Matthew McEachran said the slowing sales pattern indicates that "not even this sector is immune to the downturn".
He added that second half assumptions "might need to be trimmed back" in the light of the demise of Woolworths, which could impact sales and margins over the Christmas period, which represents around 35 per cent of Game's annual sales.
