Share Buyback: Acceptance Ratio, Taxation and What Investors Should Know

In Part 1, we discussed what a share buyback is, why companies undertake buybacks, and the difference between a Tender Offer and an Open-Market Buyback.

In this part, we take a closer look at how entitlement and acceptance work, the reservation available to Small Shareholders, how open-market buybacks work, taxation, and the key factors investors should consider before participating in a buyback.

Important: The process may vary depending on the buyback route, the company, the registrar, the broker and the terms specified in the offer documents. Investors should always refer to the latest official buyback announcement and the Letter of Offer before participating.

What Is Buyback Entitlement?

Buyback entitlement specifies the number of shares an eligible shareholder may tender, based on the applicable category and shareholding as of the record date.

For example, suppose a company announces:

Buyback entitlement: 1 share for every 10 shares held

If an eligible investor holds 100 shares, the indicative entitlement would be:

100 ÷ 10 = 10 shares

However, this does not necessarily mean that only 10 shares can be tendered or that all 10 shares will definitely be accepted.

Depending on the applicable buyback terms, an investor may be permitted to tender shares in excess of the indicative entitlement. However, acceptance of such shares depends on the applicable acceptance mechanism and the availability of shares for the buyback.

Therefore:

Entitlement ≠ Guaranteed Acceptance

This is one of the most important points investors should understand before participating.

What Is the Acceptance Ratio?

The acceptance ratio is the proportion of shares tendered that are ultimately accepted by the company.

For example:

• Shares tendered by an investor = 100
• Shares accepted = 40

The acceptance ratio in this example is:

40 ÷ 100 = 40%

Therefore, the investor would receive buyback consideration for 40 shares, while the remaining shares would remain with the investor, subject to the applicable settlement process.

The actual acceptance ratio cannot generally be known with certainty before the buyback closes because it depends on the total number of shares tendered by eligible shareholders and on the applicable acceptance mechanism.

Why Can Acceptance Be Lower Than Expected?

If a company proposes to buy back 10 lakh shares but shareholders collectively tender 30 lakh shares, the company cannot accept all 30 lakh shares.

The applicable mechanism will determine acceptance.

Do not calculate your expected outcome by assuming 100% acceptance unless the applicable terms specifically provide otherwise.

Small Shareholder Reservation

A key feature of the tender-offer route is the reservation available to Small Shareholders, subject to applicable regulations.

Under the SEBI Buy-back Regulations, a Small Shareholder is determined based on the market value of the shares held on the record date, as per the regulatory definition.

Recent buyback offer documents have applied the definition based on a market value of not more than ₹2 lakh on the record date, using the applicable exchange closing price.

Under the applicable buyback framework, the reservation for Small Shareholders is the higher of:

• 15% of the number of shares proposed to be bought back, or
• The number of shares to which Small Shareholders are entitled based on their shareholding on the record date,

subject to the applicable regulations and offer terms.

Why Is This Important?

The reservation is intended to set aside a separate portion of the buyback for eligible Small Shareholders.

However, investors should not interpret the reservation as a guarantee that all shares tendered by a Small Shareholder will be accepted.

Actual acceptance continues to depend on the applicable entitlement, the number of shares tendered, and the prescribed acceptance mechanism.

Important Point

If an investor holds multiple demat accounts, the holdings may be clubbed to determine Small Shareholder status, where required under the applicable regulations.

Therefore, investors should not assume that splitting holdings across multiple accounts will automatically create separate Small Shareholder eligibility. The applicable buyback documents may provide for clubbing holdings linked to the same PAN for this purpose.

Open-Market Buyback: How Does It Work?

An open-market buyback through the stock exchange works differently from a tender offer.

Under this route, the company purchases its own shares through the stock exchange within the applicable buyback framework. An investor who wishes to sell shares participates through the normal market mechanism rather than submitting shares for acceptance under a tender offer.

This means the investor’s transaction is executed at the prevailing market price at the time of execution. Therefore, the maximum price announced for an open-market buyback should not be treated as a guaranteed selling price.

Current Regulatory Position

SEBI amended the SEBI (Buy-back of Securities) Regulations, 2018 on July 6, 2026. The amended framework provides for the re-introduction of buy-back through the open market via stock exchanges with effect from August 1, 2026, subject to applicable regulatory conditions.

Under the revised framework, companies undertaking an open-market buyback through the stock exchange are subject to prescribed conditions, including limits and timelines. Investors should therefore refer to the latest buyback announcement and applicable documents rather than relying on older information about the stock-exchange route.

Buyback vs Selling in the Market: Which Is Better?

There is no universal answer to whether an investor should participate in a buyback or simply sell the shares in the market. The better choice depends on the investor’s circumstances and the terms of the buyback.

Factor	Tender Offer Buyback	Normal Market Sale
Price	Specified buyback price	Prevailing market price
Acceptance	May be partial	Depends on order execution
Eligibility	Subject to record date and offer terms	Generally no buyback-specific eligibility
Timing	Within the specified buyback period	During market hours
Key consideration	Acceptance ratio and tax impact	Market price and execution

For example, a buyback price that is higher than the current market price may appear attractive. However, the investor should consider the possibility of partial acceptance, taxes and charges before estimating the actual benefit.

Similarly, if the market price is close to or above the buyback price, selling in the market may be worth considering depending on the investor’s objective.

The decision should be based on the expected outcome rather than the headline buyback price alone.

Taxation of Buybacks: What Investors Need to Know

Tax treatment is an important consideration when evaluating a buyback.

For buybacks taking place on or after April 1, 2026, the tax treatment is generally governed by the capital-gains provisions applicable to the investor, including the relevant cost of acquisition, holding period and other provisions of the Income-tax Act, 2025, as applicable.

Special provisions apply to promoters and promoter shareholders, including additional tax implications under the current framework.

Simple Illustration

Suppose:

• Cost of acquisition = ₹400 per share
• Buyback price = ₹500 per share

The difference of ₹100 per share is relevant for determining the capital gain, subject to the applicable provisions, period of holding, tax rates and other factors.

However, the actual tax liability may vary depending on:

• Whether the shares are short-term or long-term
• Residential status
• Nature of the investor
• Applicable tax rate
• Promoter/promoter-group status
• Surcharge and cess
• Applicable exemptions or treaty provisions
• Other provisions of the Income-tax Act

Investors should consult their tax advisor for their specific circumstances.

Important: Tax rules can change. Always review the taxation section against the law applicable on the date of the buyback and the investor’s circumstances.

Common Mistakes and Misconceptions

1. Assuming the Price Difference Is Guaranteed Profit

A higher buyback price compared with the market price does not automatically mean guaranteed profit. Acceptance, taxes, charges and other factors affect the final outcome.

2. Confusing Entitlement with Acceptance

Entitlement indicates the applicable allocation opportunity. It does not guarantee that all entitled shares will be accepted.

3. Assuming Small Shareholder Status Guarantees Full Acceptance

The reserved category provides a separate allocation mechanism, but it does not guarantee acceptance of all shares tendered.

4. Treating the Maximum Open-Market Price as a Guaranteed Price

Under an open-market buyback, actual transactions occur through the market. Do not assume the maximum buyback price is the price at which an investor can necessarily sell.

5. Relying on an Old Buyback Process

Buyback regulations and tax rules can change. Investors should always check the latest Letter of Offer, public announcement and applicable broker instructions before participating.

Investor Checklist Before Participating in a Buyback

Before participating in a buyback, investors should check:

• Record date and eligibility
• Buyback price and total size
• Buyback entitlement
• Small Shareholder eligibility
• Applicable acceptance mechanism
• Opening and closing dates
• Current market price
• Applicable taxes
• Brokerage and other charges
• Letter of Offer and public announcement
• Broker’s latest instructions
• Whether participating in the buyback is preferable to continuing to hold or selling in the market

A buyback should therefore be evaluated as an investment decision, not simply as an opportunity to sell shares at a premium.

Key Takeaway

A buyback should not be evaluated solely on the announced buyback price. Entitlement, acceptance ratio, Small Shareholder reservation, taxation, market price and the applicable buyback mechanism can all affect the final outcome.

Investors should review the company’s latest buyback documents and understand the applicable process before deciding.
