Shares of city gas distribution companies fell up to 6.5 per cent on April 16 after all three major players – Mahanagar Gas (MGL), Indraprastha Gas (IGL) and Adani Total Gas (ATGL) – disclosed that their allocation of low-cost domestic gas under the Administrative Price Mechanisms (APM) has been reduced, with effect from today. The cheaper gas is now being replaced with more expensive New Well Gas (NWG), which the companies said, is going to hurt their profitability.
