Vedanta demerger 2026: key dates, share ratio explained

Vedanta is entering the execution phase of its long-awaited demerger, a restructuring that will separate four businesses into individually listed companies while Vedanta Ltd remains listed. The board has fixed May 1, 2026 as the record date and also referred to it as the effective date. But because May 1 is a market holiday (Maharashtra Day), the practical timeline shifts to earlier trading sessions on the stock exchanges.

For equity investors, the operational takeaway is straightforward: under India’s T+1 settlement system, shares need to be credited to the demat account before the ex-date mechanics kick in. The market communications around the record date and settlement cycle imply April 29, 2026 is likely the last day to buy Vedanta shares and still be eligible for the demerger entitlements.

What Vedanta’s demerger changes

Vedanta’s current share price reflects the combined value of the existing structure, which includes multiple businesses under one listed entity. After the record date, the same Vedanta share will represent the value of Vedanta excluding the four demerged companies. The separated companies will be listed later on BSE and NSE, with the listing dates not disclosed in the available exchange and brokerage communications.

The restructuring creates a period where eligible shareholders will hold economic exposure to the demerged entities, but may not be able to trade them until listing. This “discovery lag” matters because the market will immediately adjust Vedanta’s traded price when it turns ex-demerger, while the new shares will only become tradeable after separate listings.

Record date vs ex-date: why April 30 matters

Vedanta has set May 1, 2026 as the record date for determining eligible shareholders. However, since the exchanges are shut on May 1, the stock is set to trade ex-demerger from April 30, 2026. Investors buying on April 30 or later will be buying the ex-demerger Vedanta share and will not receive the four new shares.

The reason is settlement timing. With T+1, shares bought on a trading day are credited to the buyer’s demat account the next trading day. So, to have shares credited by April 30 (the ex-date), the purchase needs to happen by April 29.

Key dates investors must track

Demerger ratio and what shareholders will receive

In its exchange filing dated April 20, Vedanta said each eligible shareholder will receive one share each in:

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

This is communicated as a 1:1 entitlement for every Vedanta share held. Scheme details referenced in the material also state that Talwandi Sabo Power Limited will issue one share of face value INR 10 for every Vedanta share of face value INR 1. Other referenced issuance details include VAML (face value INR 1), and Malco Energy and Vedanta Iron and Steel (face value INR 1 each) per Vedanta share held.

Broker notes in the material also describe the demerged verticals as Aluminium, Power, Oil and Gas, and Steel, alongside the residual Vedanta Ltd.

Special pre-open session on April 30 for price discovery

Vedanta shares will undergo a Special Pre-Open Session (SPOS) on April 30 from 9:15 am to 9:45 am. Normal trading is scheduled to resume at 10:00 am, reflecting the newly discovered ex-demerger price.

The adjustment is expected to be sharp because the market will remove the value attributed to the four demerged businesses from the traded price of Vedanta Ltd. The valuation of the demerged entities is described as being derived from the difference between Vedanta’s closing price on April 29 and the opening price discovered during the SPOS on April 30.

What brokerages and index providers have flagged

Nuvama has said Vedanta will continue to be part of the Nifty Next 50, while the demerged entities (Aluminium, Power, Oil and Gas, Steel) will appear as dummy constituents until their listing. Nuvama also noted Vedanta’s weight will be auto-adjusted on MSCI and FTSE indices.

On valuation, ICICI Direct estimated that when Vedanta starts trading ex-demerger on April 30, the stock could trade in the range of INR 300-325 per share, compared with its then-current range of INR 720-760 cited in the material. ICICI Direct also estimated a combined sum-of-parts valuation of INR 820 per share across all five entities and advised investors to Hold Vedanta shares ahead of the demerger.

Stock price moves into the event

The stock has seen active positioning ahead of the record date timeline. The material notes Vedanta shares rose around 1.56% to INR 754.10 on a Tuesday session before declining to INR 742.00, rebounding from intraday lows. Separately, it notes that on Friday, April 24, the scrip fell around 2% to INR 721.10.

The stock is described as being over 11% below its 52-week high of INR 794.90 (touched on April 21, 2026) following the demerger announcement, while still over 77% above its 52-week low of INR 398.85 (hit in May 2025). These moves provide context, but the most visible price change is expected around the ex-demerger adjustment and subsequent listing of the separated companies.

Derivatives and trading mechanics: what changes around April 29-30

For derivatives traders, the communication highlights a compressed window. All existing Vedanta F&O contracts are set to expire on April 29, 2026, and new contracts are expected to be reintroduced from April 30 at 10:00 am, after the special pre-open process.

The material also notes no fresh F&O positions are allowed from April 28, making position planning tighter. With physical settlement obligations in Indian equity derivatives, traders are expected to focus on margin readiness and share availability to avoid settlement shortfalls around the expiry and adjustment.

When will the new companies list?

The filing and market notes in the provided material state the listing dates on BSE and NSE have not yet been disclosed. A separate expectation cited is that the four new companies could list within four to eight weeks of the May 1 record date, placing a probable window in June to July 2026, subject to regulatory approvals.

Until listing happens, investors will not have a traded market price for the newly allotted shares. That gap is a normal feature of large restructurings, and it is why the ex-date price adjustment and the later listing process are treated as separate milestones.

What investors should verify before the cut-off

Eligibility is linked to holdings being in delivery form before the record date. The communication says the credit of demerged shares is expected to be automatic once the eligibility cut-off is met, with no action required beyond holding the shares on the relevant date.

As noted by Santosh Meena, Head of Research at Swastika Investmart in the material, investors seeking demerger benefits should buy on or before April 29, 2026, since April 30 is the ex-date under the T+1 settlement cycle and holdings as of the record date determine eligibility.

Conclusion

Vedanta’s demerger is scheduled around a record date that falls on a market holiday, shifting the investor checklist to April 29 (last eligible buy day) and April 30 (ex-demerger trading and special pre-open price discovery). Shareholders eligible on the record date are set to receive one share each in VAML, TSPL, Malco Energy, and Vedanta Iron and Steel for every Vedanta share held. The next key milestone is the separate listing of the new companies on BSE and NSE, which the available material says has not been dated yet.
