SuperValu has announced that it recorded retail sales of €2.6bn in 2015.
The grocery retailer plans to invest €28m this year, opening five new stores and adding 350 jobs to its network.
SuperValu outperformed the market with 4.3% growth over the last twelve weeks of the year, and currently holds 25% of the market.
Martin Kelleher, Managing Director of SuperValu, said: "We are pleased to announce that we have achieved a new sales milestone in what is a highly competitive marketplace.
"As the number one supporter of the Irish food industry, we source from over 1,800 Irish suppliers – more than any other grocery retailer in the Irish market – equating to an economic contribution of €2.19 billion.
"From 100% fresh Irish meat, scratch bakeries in-store, locally-sourced fruit & veg, specialist fish counters and our Food Academy suppliers, we continue to give shoppers the best locally sourced food. As our stores are independently owned and operated, this means even more money goes back into the local economy."
SuperValu online shopping was a key sales driver for the retailer last year, growing by 32% for the last six months of the year and projected to grow over the next 12 months.
The grocery retailer’s online shopping active customer base grew by 23.6%. The SuperValu Online Shopping App had 129% more downloads and visits to SuperValu on mobile phones increased by 37% in 2015.
SuperValu serves more than 2.6 million customers every week and has 221 stores nationwide.
Together with its retail partners, SuperValu employs approximately 14,500 staff, making it one of the State’s largest private sector employers.
