Adani Group has planned to diversify its airport business and expand its retail business from airports to highways and malls in a phased manner. The port-to-power conglomerate intends to expand from around 50 stores this year to nearly 310 next year, according to the Economic Times. This comes at a time when the billionaire Gautam Adani-led conglomerate is eyeing to increase its revenue stream beyond non-aeronautical sources from the airport venture.
