The Co-operative Group's sales soared last year as its acquisition of Nisa convenience stores paid off.
The business also hailed a year of community initiatives, as it returned £79 million to members and local projects.
Total revenues jumped 14% to £10.2 billion in the 52 weeks to January 5, driven by the addition of Nisa and a strong performance in the food business.
Like-for-like food sales were up 4.4%, marking the fifth consecutive year of growth.
Profit before tax from continuing operations was up 27% to £93 million. Underlying pre-tax profits were flat at £43 million.
It follows Co-op's acquisition in 2017 of convenience store network Nisa, which formally completed in May of last year and has seen Co-op products appear in the shops.
Steve Murrells, chief executive of the Co-op, said the integration of Nisa had been a "game-changer" which significantly expanded the group's food footprint.
Meanwhile, the Co-op funeral division saw a 1% decline in revenue, due to heated competition in the market.
Co-op has been putting the screws on Dignity, the other largest player in the sector, by slashing the price of its simple funeral package.
The competition watchdog is to probe the funeral market amid a consistent pattern of above-inflation price increases.
