Vedanta demerger: Stock falls 62% as it turns ex-date

What happened in Vedanta shares on the ex-demerger day

Vedanta Ltd shares showed a sharp one-day “fall” on Thursday across trading platforms as the stock began trading on an ex-demerger basis. On the NSE, the stock opened at Rs 289.50 after a special pre-open session. That price signalled a 62.58% decline from Wednesday’s close of Rs 773.60.

The move was not a typical sell-off driven by fresh negative news. It reflected a price adjustment to account for value that will shift into the newly demerged companies. Some apps showed the adjustment as a fall of up to about 63% because the pre-demerger price included the value of businesses that are being spun off.

Why the price looked like a 62% drop

The steep adjustment is linked to how ex-demerger trading works. Once a stock turns ex-date, the traded price represents the “residual” listed company after separating the value of businesses that will be housed in new entities. In this case, Vedanta’s traded price excluded the value of four verticals that are being carved out.

The exchange also noted that the difference between Wednesday’s closing price and Thursday’s discovered price will be used to determine the valuation of the demerged entities. That mechanism is designed to create a clean reference point for the market, especially when multiple entities are being created from one listed company.

The special pre-open session and how price discovery was done

The NSE conducted a special pre-open session between 9:15 am and 9:45 am on Thursday to determine the adjusted ex-demerger price. Normal trading in Vedanta then began from 10 am.

This approach was used because the record date for the corporate action is May 1, and trading is shut that day due to Maharashtra Day. With markets closed on the record date, the exchange used the prior trading day for the ex-date adjustment and a structured price discovery process.

Record date, ex-date, and who is eligible

Vedanta announced May 1, 2026 as the record date for the demerger. Since May 1 is a market holiday, the stock traded ex-demerger on Thursday, April 30.

Eligibility is tied to holdings as of the record date. Investors who bought Vedanta on or before Wednesday, April 29 are eligible for the demerger entitlements, while investors buying from April 30 onwards are not eligible for the benefits. The article also highlighted that Wednesday, April 29 was the last day to buy the “consolidated” Vedanta for those entitlements.

What shareholders will receive in the demerger

As per the approved scheme outlined in the report, the demerger is being executed as a simple vertical split. Eligible shareholders will receive one share each of the newly demerged entities in a 1:1 ratio for every share of Vedanta held.

The demerger will result in the creation and listing of four new entities over time. The businesses being separated include aluminium, power, oil and gas, and steel and ferrous materials.

The four new companies to be listed

The demerger plan will create four listed entities later, subject to regulatory approvals and completion of processes. The article named the companies as:

• Vedanta Aluminium Metal Ltd (VAML)
• Talwandi Sabo Power Ltd (TSPL)
• Malco Energy Ltd (MEL)
• Vedanta Iron and Steel Ltd (VISL)

The report also stated that the demerged entities will not be traded live until they are listed, so their market capitalisation and price will remain static until listing.

What stays with the residual Vedanta

After the restructuring, Vedanta Ltd will continue as a listed company. One part of the coverage said the remaining Vedanta entity would house key businesses including Zinc India (Hindustan Zinc Ltd), Zinc International, Copper, and Ferro Chrome.

ICICI Direct said the residual Vedanta would derive the bulk of its value from its stake in Hindustan Zinc. Another section of the report cited an analyst view that the residual valuation would be anchored largely by Vedanta’s 63.4% stake in Hindustan Zinc, along with copper, ferro chrome and an emerging displays venture.

Broker views and indicative trading ranges

Brokerages flagged that the traded price of Vedanta would adjust sharply on the ex-date, with ranges varying by methodology and assumptions.

ICICI Direct said the stock price is expected to adjust for the demerger and trade in the range of Rs 300-325 per share, noting that the estimate is indicative as the brokerage awaited the exact allocation of net debt across the resulting entities. SBI Securities’ Head of Fundamental Research Sunny Agrawal put the residual value range at Rs 250-290 per share post the special pre-open session. Separately, Nuvama and ICICI Direct were also cited as seeing Vedanta Aluminium as an attractive demerged entity, with an expected listing valuation of Rs 400-plus per share.

Market cap shift and index considerations

Post-adjustment, Vedanta’s total market capitalisation was reported at around Rs 1.13 lakh crore. Another segment cited Nuvama Institutional Equities estimating Vedanta’s post-demerger market capitalisation at nearly Rs 1.14 lakh crore, compared with more than Rs 3 lakh crore at the end of Wednesday’s session.

The report also flagged index mechanics. Vedanta has a stated weight of about 5.2% in the Nifty Next 50, and a separate reference said the weight could drop to around 2.3% after the demerger. It also noted that Vedanta is part of MSCI Emerging Markets and FTSE indices, and that its weight would be auto-adjusted on MSCI and FTSE.

Key facts at a glance

Why this restructuring matters for investors

The stated objective of the demerger is to simplify Vedanta’s corporate structure and allow investors to assess each business as a pure-play company rather than as part of a diversified conglomerate. The ex-date adjustment is a practical reflection of that separation, since the market begins valuing the “residual” Vedanta independently from the soon-to-be-listed entities.

In the near term, the article highlighted potential for higher volatility, especially around passive flows and index adjustments. For investors focused on entitlements, the critical takeaway is that buying after the ex-date does not provide the right to receive shares of the demerged companies.

What to watch next

The company indicated the demerger would become effective from May 1, with shareholders receiving shares in the newly created entities based on holdings as of the record date. However, the dates for the four new listings were not disclosed in the report.

Until those listings occur, investors will track the regulatory process, the eventual listing timelines, and how the market values each vertical once trading begins in the demerged entities.
