Reliance Industries is considering selling an additional 8-10% stake in Reliance Retail Ventures Ltd (RRVL) to raise funds for expansion and debt retirement before its planned IPO. The stake sale would be done in tranches over 12-15 months and is crucial for the success of RRVL's IPO, as the current valuation of $100 billion is considered too large for the market to absorb. The company aims to dilute another 7-10% equity to make the IPO size manageable. The proceeds from the stake sales will be used for store expansion and debt reduction.
