Radhakishan Damani eyes fivefold growth in a market Mukesh Ambani wants to dominate

Indian billionaire Radhakishan Damani’s discount supermarket chain, DMart, plans to boost its store count fivefold as it seeks to grow market share and hold its own against aggressive expansion from the likes of Mukesh Ambani’s Reliance Retail Ltd NSE -0.75 %.

Avenue Supermarts NSE 0.81 % Ltd., which currently runs the fourth-largest number of convenience stores in India, could scale up the chain known for its knockdown prices on everything from lentils to laundry powder to 1,500 supermarkets from 284, Chief Executive Officer Neville Noronha said in an interview. He declined to give a timeline or estimate the investment needed.
