Reliance Industries is expected to report 15-17% year-on-year growth in September-quarter EBITDA, driven by a sharp recovery in its oil-to-chemicals business. Brokerages expect stronger refining margins, higher throughput and a weaker rupee to offset subdued retail and oil and gas performance. Investors will track O2C profitability, Jio Platforms’ earnings and retail margins as RIL announces results.
