Vedanta demerger 2026: key dates, ratio and F&O rules

What Vedanta has announced

Vedanta Limited has announced a demerger that will split its current structure into five independent business entities. Four of these will be new, separately listed companies over time, subject to regulatory approvals. The existing listed company, Vedanta Ltd, will continue to remain listed after the corporate action. The stated intent of the reorganisation is to create sector-focused businesses that can be valued separately.

The five resulting entities

Under the announced structure, the group will be organised into the following entities:

• Vedanta Aluminium
• Vedanta Oil & Gas
• Vedanta Power
• Vedanta Iron & Steel
• Vedanta Ltd (the existing entity that remains listed)

Some businesses are also referenced through their current company names in the scheme communication. Talwandi Sabo Power Limited is to be renamed Vedanta Power Limited, and Malco Energy Limited is to be renamed Vedanta Oil and Gas Limited.

Record date, effective date and why the ex-date shifts

Vedanta’s board has fixed May 1, 2026 as the record date for determining eligible shareholders, and also referred to May 1, 2026 as the effective date. However, May 1 is a market holiday due to Maharashtra Day, and trading on BSE and NSE will remain shut. As a result, Vedanta shares are set to trade ex-demerger from April 30, 2026.

This shift matters because India follows a T+1 settlement cycle for equities. Investors who want to be eligible for the demerger benefits need to purchase shares at least one trading day before the ex-date.

Investor eligibility: last buy date and delivery holding requirement

With April 30 as the ex-date and markets closed on May 1, the timeline in the exchange and market communication implies:

• Investors must buy shares on or before April 29, 2026 to qualify.
• Buyers on or after April 30, 2026 will not receive demerger benefits.

Eligibility is also linked to holding type. Investors are required to ensure shares are held in delivery form before the record date to be eligible for the demerger entitlements.

Demerger ratio and what shareholders receive

The demerger ratio communicated is 1:1. For every one share held in Vedanta, shareholders are expected to receive one share in each of the four new companies. This keeps proportional ownership consistent across the verticals at the point of allotment.

In scheme details referenced in the available material, Talwandi Sabo Power Limited is to issue one share with a face value of INR 10 for each Vedanta share with a face value of INR 1. The allotment structure is presented as uniform across the resulting entities from a share count perspective.

Price discovery on April 30: special pre-open session

Because May 1 is a trading holiday, Vedanta is set to conduct a special pre-open session (SPOS) on April 30, 2026 for price discovery of the ex-demerger Vedanta Ltd. The special session is scheduled from 9:15 AM to 9:45 AM, with normal trading to begin from 10:00 AM.

The available explanation also describes how the implied prices for the demerged entities may be derived. It links the calculation to the difference between Vedanta’s closing price on April 29 and the opening price discovered in the SPOS on April 30.

Derivatives reset: early expiry and physical settlement

The derivatives segment is scheduled to see procedural changes around the demerger. As per the circular details shared, all existing Futures and Options contracts in Vedanta will expire early on April 29, 2026, even if their original expiries were later.

Contracts with expiries on 26 May, 30 June, and 28 July are specifically referenced as being brought forward to April 29. The settlement framework described includes physical settlement for open positions, with the final settlement price based on the closing price in the cash market on April 29. Mark-to-market (MTM) settlement is described as completing on April 30, 2026 (T+1).

Trading restrictions and reintroduction of contracts

The same communication flags that no fresh positions will be allowed in the F&O segment from Tuesday, April 28 onward. It also states that the stock will be reintroduced in the derivatives segment on April 30 at 10:00 AM, following price discovery.

For positions that lack sufficient fund value, or insufficient stock in the case of short positions, the broker and exchange process described allows for square-off anytime after 10 AM on Wednesday, April 29, 2026, on a best-effort basis. The intent of the process is to ensure orderly clearing and settlement as contracts are closed.

Index impact and treatment of new entities

Post demerger, changes in index composition are expected. Vedanta Ltd is expected to continue in the Nifty Next 50, with an auto-adjusted weight referenced at around 2.3%.

The demerged entities are described as temporary constituents in various indices until they are officially listed on the exchanges. This “temporary” handling is intended to bridge index continuity between the record date and the point when the new companies begin regular trading as independently listed stocks.

Why the four new stocks may not enter F&O immediately

The newly demerged entities are not expected to be included in derivatives immediately. The criteria referenced include at least six months of trading history, sufficient liquidity, and regulatory approval from the Securities and Exchange Board of India. This means F&O availability, if it happens, would come only after trading history and quantitative thresholds are met, and after approvals.

Key facts table

Background milestones referenced in the scheme communication

The scheme is described as having progressed through multiple approvals. It references approval by the Mumbai bench of the National Company Law Tribunal (NCLT) in December 2025, after approvals from shareholders, creditors, and stock exchanges.

It also references a board approval for implementation dated April 20, 2026. Separately, a target listing timeline for the new entities is mentioned around May 15, 2026, subject to final approvals, and an overall completion deadline extended to June 30, 2026.

Corporate changes mentioned alongside the demerger

The material also references an internal transfer ahead of the split: Vedanta’s stake in Bharat Aluminium Company Limited is to be moved to its aluminium arm. The same note attributes turnover of ₹15,909 crore and 39% of net worth to Bharat Aluminium Company Limited.

These details matter mainly because they affect which businesses and assets sit inside each post-demerger entity when the market begins to assign separate valuations.

What investors and traders typically need to do next

For equity investors, the operational checklist in the communication is straightforward: buy by April 29 if seeking eligibility, and ensure holdings are in delivery form before the record date. The credit of shares is described as automatic, with no specific action required beyond meeting the eligibility cut-off.

For derivatives traders, the practical focus is on managing the early expiry on April 29, understanding physical settlement obligations, and maintaining sufficient margin or shares to avoid settlement shortfalls. With no fresh F&O positions allowed from April 28, position planning is constrained into a short window.

Conclusion

Vedanta’s May 1, 2026 record date and the April 30 ex-date create a tight timetable for both investors and F&O traders. The demerger will split the business into five entities with a 1:1 entitlement in each newly carved-out company for eligible shareholders.

The most immediate market-facing change is the April 29 early expiry of existing Vedanta F&O contracts and the reintroduction of derivatives after price discovery on April 30. The next set of milestones to watch are the listing steps for the new companies, which are expected to proceed subject to regulatory approvals.
