"When pricing is low, capex is required to deliver better customer experience amid the upsurge in data throughput and demand," Vittal said during a recent earnings call.

"Cash raised from the stake sale in the DTH business to Warburg Pincus should enable Bharti Airtel to fund capex on the India wireless business," Morgan Stanley said in a note seen by ET.
JM Financial said the transaction, though not truly about value-unlocking, would help Bharti Airtel "marginally reduce its balance sheet leverage". It also indicated a possible listing of the Bharti group's DTH business in future.
