Symbol group Nisa has reported a 4.2% rise in sales in the last year as the convenience market continues to boom.

Nisa reported a record turnover of £1.58bn and paid a record £4.9m dividend to members.

It said profits before tax rose from £1.7m to £3.8m in the year to April 1.   

Nisa’s finance director Simon Webster said: “Despite the company being faced with a number of challenges this year, such as members selling out to multiple operators, the business has shown its resilience and has achieved pleasing sales and volumes figures for the 2011/2012 financial year.

“As a result of this we are once again able to reward our members with a significant surplus and dividend payment.”

He added: “The fact we operate on a low profit margin which is passed back to our membership, demonstrates our unique focus on creating benefits to members rather than to the central business or profits for external shareholders.”

Nisa separated from the Today’s Group in January 2012.
