Understanding the Acceptance Ratio in Share Buybacks
This article”Share buyback a complete Investor’s guide” explores various aspects of share buybacks, including the recent surge in buybacks, how to interpret promoter participation, the justification for buyback premiums, and when buybacks may signal potential red flags.
A share buyback is a way for companies to return cash to shareholders, much like dividends. To fully grasp its implications, investors must compare buybacks with dividend distributions—the other widely used method of returning cash to shareholders. By understanding the factors influencing both buybacks and dividends, investors can gain insights into the intentions and motivations of companies and their management behind these decisions
Let’s compare share buybacks and dividend payments using a hypothetical company with a single shareholder. This will help us understand how tax rules affect the cash flow from the company to the shareholder.
1. Understanding the Tax Impact on Dividends vs. Share Buybacks
Recently, the Indian government introduced a tax on dividends exceeding ₹10 lakh in the hands of shareholders. This tax is in addition to the Dividend Distribution Tax (DDT) that companies already pay. However, this extra tax does not apply to share buybacks—making them a potentially more tax-efficient option for returning money to shareholders.
Scenario 1: Dividend Distribution
Let’s say a company decides to distribute ₹100 crore as a dividend. Here’s how the taxes play out:
The company must first pay ₹17 crore as Dividend Distribution Tax (DDT) to the government.
This leaves only ₹83 crore for shareholders.
If there is only one shareholder (the promoter) receiving the entire ₹83 crore, they must pay an additional 10% tax on any amount above ₹10 lakh.
This results in another ₹8 crore in taxes.
So, from the ₹100 crore that the company originally intended to distribute:
The government collects ₹25 crore (₹17 crore from the company + ₹8 crore from the shareholder).
The shareholder actually receives only ₹75 crore after taxes.
This means that a significant part of the dividend payout goes to taxes rather than benefiting shareholders.
Share Buyback Taxation in 2025: A Revised Perspective
Now, let’s consider a scenario where the company decides to buy back shares worth ₹100 crore instead of distributing dividends.
The company announces a ₹100 crore share buyback, and the shareholder sells shares back to the company.
Under the current 2025 tax regime, buybacks are subject to a 20% buyback tax at the company level.
This means that before distributing ₹100 crore to shareholders, the company must first pay tax to the government.
Tax Implications of Buyback in 2025
The company must gross up the buyback amount to account for the 20% tax.
This means the total payout from the company becomes ₹125 crore (₹100 crore for the shareholder + ₹25 crore in taxes).
The shareholder receives the full ₹100 crore without any additional tax liability, as the buyback tax is already deducted at the company level.

Key Takeaways
Before 2020, share buybacks were more tax-efficient than dividends because they avoided additional taxes for shareholders.
Post-2020 reforms introduced a 20% buyback tax, making buybacks less advantageous but still preferred in some cases.
In 2025, companies continue to use buybacks strategically because they help boost earnings per share (EPS) and indicate confidence in the company’s valuation.
While buybacks no longer provide a major tax advantage over dividends, they remain a favored method for returning capital to shareholders while potentially enhancing stock value.
2. Understanding Promoters’ Participation in Share Buybacks
Investor Query:
When a company announces a share buyback, it generally indicates that management believes the stock is undervalued. However, I’ve noticed that in some cases, promoters also participate in the buyback. If they truly think the shares are undervalued, why would they sell instead of holding onto them? Could promoter participation in a buyback be a negative signal?
Response:
You’re right that a buyback usually suggests that the company views its stock as undervalued. However, there are other factors to consider:
Tax Efficiency: Companies often use share buybacks as a tax-efficient way to return capital to shareholders, especially when dividend taxation is higher. Promoters may participate in the buyback to optimize their tax liabilities.
Liquidity Needs: Promoters might sell in the buyback to free up capital while ensuring the transaction is conducted in a structured and market-friendly manner.
Stock Valuation Perspective: In some cases, promoters may feel that the stock is fairly valued or even overvalued, making the buyback an opportunity to partially exit at an attractive price.
Premium to Market Price: If the buyback is offered at a significant premium to the current market price, promoters—like any other shareholder—may find it a compelling opportunity to sell.
While promoter participation is not always a negative sign, investors should carefully analyze the company’s financials, rationale for the buyback, and whether it aligns with long-term shareholder value creation.
3. Are Share Buybacks a Sign of Undervaluation? When Do They Become a Red Flag?
Investor Query:
Why do companies announce share buybacks? Instead of making an announcement, can’t they just start buying shares like regular investors?
Often, buybacks are announced at a maximum price higher than the prevailing market price. Does this mean the stock is undervalued and will likely rise? Isn’t this effectively a signal from the company that its shares are undervalued?
Also, under what circumstances can a share buyback be considered a red flag? Could you provide some examples?
Response:
Regulatory Requirements & Tax Efficiency Companies must announce share buybacks in advance to comply with regulatory guidelines. Buybacks serve as an alternative to dividends, often providing a more tax-efficient way of returning capital to shareholders. Additionally, they can enhance earnings per share (EPS) by reducing the number of outstanding shares.
Buybacks & Stock Valuation Investors should independently assess a stock’s valuation rather than relying on a buyback price as a benchmark. In some cases, companies announce buybacks at a significant premium to benefit insiders looking to exit at a higher price, potentially transferring wealth from remaining shareholders to those selling.
Sometimes, buybacks are used to offset dilution from excessive stock-based compensation (ESOPs) to maintain EPS levels.
When Buybacks Become a Red Flag Buybacks may signal potential concerns when:
They are conducted at an excessively high premium to the market price, possibly benefiting select stakeholders rather than all shareholders.
They serve as a short-term measure to artificially boost EPS rather than a strategic allocation of capital.
The company is funding the buyback using excessive debt, which may strain financial health in the long run.
Numerous such instances have occurred in Indian markets, where buybacks were used more for financial engineering than genuine value creation.
During share buybacks, companies often offer a premium over the current market price to encourage shareholder participation. For instance, TTK Prestige approved a buyback at ₹1,200 per share, a 25% premium over its closing price of ₹960 on the announcement day. Similarly, Tata Consultancy Services (TCS) announced a buyback at ₹4,150 per share, reflecting a 15% premium.
Given these examples, how can minority shareholders assess whether a buyback is beneficial? What premium level is considered reasonable, and how should investors interpret such buyback offers?
Response:
Determining an appropriate premium for a share buyback involves several considerations:
Purpose of the Buyback:
Enhancing Shareholder Value: Companies may repurchase shares to signal confidence in their valuation, aiming to boost earnings per share (EPS) and return on equity.
Tax Efficiency: Buybacks can be a tax-efficient method to return capital to shareholders compared to dividends.
Premium Justification:
Market Norms: Premiums typically range between 10-20%. For example, TCS’s 15% premium aligns with this standard.
Higher Premiums: Premiums exceeding this range may warrant scrutiny. For instance, Symphony announced a buyback at ₹2,500 per share, offering a 51% premium over its last traded price.
Evaluating the Buyback:
Financial Health: Assess whether the company has sufficient reserves for the buyback without compromising growth initiatives.
Promoter Participation: If promoters are participating, it could indicate their intent to reduce holdings, which may have various implications.
Long-Term Prospects: Consider the company’s future growth potential and whether the buyback aligns with long-term value creation.
5. How Does Market Cap Adjust After a Share Buyback?
Understanding the Impact of Share Buybacks on Market Capitalization
Let’s consider a hypothetical scenario:
A company has 100 shares, each priced at ₹100, resulting in a market capitalization of ₹10,000.
The company announces a buyback of 30 shares at ₹120.
After the buyback, 70 shares remain in circulation.
If the share price adjusts to ₹120, the new market cap would be ₹8,400 (70 × 120).
Key Questions:
How does the market determine the share price after the buyback? Theoretically, market cap should remain stable, meaning the share price post-buyback could be calculated as: Market Cap ÷ Remaining Shares = ₹10,000 ÷ 70 = ₹142.85 per share However, real-world factors like investor sentiment, liquidity risks, and macroeconomic trends can influence the actual price.
What happens to the shares bought back by the company?
The repurchased shares are usually categorized as “Treasury Stock”, meaning they are not available for trading.
The company can either extinguish these shares permanently or reissue them later through methods like an IPO, FPO, or QIP.
Follow-up Question:
Shouldn’t the market cap reduce by the buyback amount?
If we assume a direct reduction in market cap by ₹3,600 (30 shares × ₹120), the new market cap would be: ₹10,000 – ₹3,600 = ₹6,400 This implies a new share price of ₹6,400 ÷ 70 = ₹91.
However, market cap and cash reserves are not always directly correlated. Other factors, such as management quality, cash utilization efficiency, and investment opportunities, influence how market cap reacts to a buyback.
Understanding the Acceptance Ratio in Share Buyback
The acceptance ratio in a share buyback represents the percentage of shares that a company accepts for repurchase from shareholders who have tendered their shares.
Formula for Acceptance Ratio:
Acceptance Ratio=Total Shares Accepted for Buyback Total Shares Tendered by Shareholders\text{Acceptance Ratio} = \frac{\text{Total Shares Accepted for Buyback}}{\text{Total Shares Tendered by Shareholders}}Acceptance Ratio=Total Shares Tendered by Shareholders Total Shares Accepted for Buyback
6. How to Estimate the Acceptance Ratio?
Check the Buyback Offer Details:
The company discloses the total number of shares reserved for buyback in its filing with stock exchanges.
This information is also available in the Letter of Offer and buyback advertisements in newspapers.
Consider Shareholder Categories:
Buybacks are usually divided into two categories:
Retail Shareholders (holding shares worth ₹2 lakh or less)
General Category (Institutional and large investors)
Each category has a specific reservation in the buyback, impacting the acceptance ratio.
Estimate Share Tendering:
The acceptance ratio is based on the assumption that all eligible shareholders will tender their shares.
However, in reality, not all shareholders participate, which can lead to a higher final acceptance ratio for those who do.
Example:
Suppose a company announces a buyback of 10 lakh shares, with 2 lakh shares reserved for retail shareholders.
If retail shareholders collectively tender 5 lakh shares, the acceptance ratio = (2 lakh ÷ 5 lakh) = 40%.
If fewer shareholders tender (say 3 lakh shares), the ratio would increase to 66.67%.
Key Takeaways:
The official acceptance ratio is available in the buyback documents.
The final acceptance ratio depends on shareholder participation.
Higher tendering results in a lower acceptance ratio and vice versa.
