An impairment charge has pushed Collins Foods Limited (ASX:CKF) to an annual loss despite generating a 30 per cent jump in revenue on the back of strong KFC sales. 

The operator of food service retail outlets booked a net loss of $10.4 million, after reporting a profit of $14 million the year before. 

The result was impacted by a $37.5 million charge on its Sizzler chain in Australia. 

CEO Graham Maxwell says the group will no longer invest further capital into the chain locally in order to pursue more attractive growth opportunities. 

A final fully franked dividend of 6.5 cents per share has been declared, taking the full year payout to 11.5 cents per share.
