It estimates that turnover has grown by nearly 12% and volumes by 4% in the year ending March 2009. In that period it increased its net number of retail members by 135 and its number of stores by 260.
The majority of new stores recruited have adopted the recently rebranded Nisa fascia, which will now be rolled out across the country.
The old blue fascia is to be phased out and replaced by the white fascia, which was trialled at its Store of the Future in Maylandsea.
Over the coming year, the group will concentrate on passing on any profits by way of discount prices to members.
"We had some upheaval with the attempted merger with Costcutter in 2006, but we are now experiencing a prolonged period of stability despite the recession," said chief executive Neil Turton. "We have paid for all the big things, such as the Member Support Centre, and are now in a position to be able to pass on great prices to our members for the next few years, which is exactly what retailers are looking for at the moment."
Nisa-Today's also unveiled a new strategy to encourage more retailers to adopt its fascia, which is not yet a universally recognised brand.
