Mukesh Ambani's ambitious telecom venture Reliance Jio reported a loss of Rs 270.59 crore in its first quarterly financial performance for the period ended September 30. However, Reliance Industries Ltd's fiscal second-quarter net profit at Rs 8,097 crore just about met the expectations despite the Jio loss, on the back of healthy refining margins. Reliance Jio Infocomm Ltd (Jio), a wholly owned subsidiary of Reliance Industries Limited (RIL), which commenced its business in September last year reported its revenue at Rs 6,147 crore and EBITDA at Rs 1,443 crore posting a margin of 23.5%. The company said that it had recorded a positive EBIT due to strong user additions and cost efficiencies, which made a positive contribution to RIL's Q2 results. According to the company, the subscriber base of Jio grew to 138.6 million by the end of September.
