Vedanta, a leading metals and mining conglomerate, is set to undergo a significant demerger, splitting into five distinct publicly listed companies: Vedanta Aluminium, Vedanta Oil & Gas, Vedanta Power, Vedanta Iron & Steel, and the remaining Vedanta Limited. The effective date for the demerger is May 1, 2026, with shareholders receiving shares in the new entities at a 1:1 ratio. Due to a stock market holiday on May 1 for Maharashtra Day, trading will commence on April 30, marking the ex-date for the demerger. Investors must purchase shares before this date to be eligible for the benefits. A special pre-open session for price discovery will occur on April 30, determining the opening prices of the demerged entities based on Vedanta Ltd's closing price on April 29. The demerger will impact derivatives, as all current contracts will expire on April 29, and new entities will not be included in derivatives until they meet trading history requirements. Listing timelines for the new entities are anticipated to range from 4 to 8 weeks after the demerger, depending on regulatory approvals. This demerger is expected to adjust Vedanta's weight in the Nifty Next 50 index from 5.2% to 2.3%, influencing passive investment flows significantly.
