SEBI proposes 66-day buyback window with minority shareholder safeguards
Synopsis
SEBI is tightening its buyback rulebook with a 66-day completion deadline, a 40% front-loading mandate, and a promoter share freeze — signalling a shift from voluntary compliance to structural enforcement in how listed companies return capital to shareholders.
Key Takeaways
SEBI has proposed a 66 working-day completion window for open-market buybacks through stock exchanges.
Companies must deploy at least 40% of the buyback size in the first half of the offer period.
Promoters and associates may face ISIN-level freezing of shares during the buyback period as an additional safeguard.
A separate trading window for buyback transactions is proposed to be removed; trades will go through the normal market mechanism.
Companies must notify shareholders via electronic mode within one working day of the public announcement.
Buybacks will be required to not breach minimum public shareholding norms , with an explicit regulatory provision to enforce this.
The Securities and Exchange Board of India (SEBI) has proposed a series of additional measures to strengthen its framework for reintroducing open-market share buybacks through stock exchanges, including a 66 working-day completion timeline and new protections for minority shareholders. The proposals, developed in consultation with the Primary Market Advisory Committee (PMAC), aim to balance regulatory efficiency with investor interests.
Key Structural Changes Proposed
Under the revised framework, companies undertaking open-market buybacks would be required to complete the process within 66 working days from the offer opening date. Additionally, companies must deploy at least 40 per cent of the total buyback size within the first half of the offer period — a front-loading requirement designed to prevent companies from dragging their feet on actual repurchases.
SEBI noted that the 66-day timeline is necessitated by recent amendments under the Finance Act, 2026 to the Companies Act, which altered the permissible gap between two successive buyback offers. The regulator explicitly rejected PMAC's earlier suggestion of a six-month window, arguing it could render buybacks irrelevant amid fast-changing market conditions and make it harder for shareholders to track the process.
Safeguards for Minority Shareholders
As an additional layer of protection, SEBI has proposed that it may direct the freezing of shares and other specified securities held by promoters and their associates at the ISIN level during the entire buyback period. Existing rules already bar promoters from dealing in or transferring company shares from the date of the board decision until the buyback closes, but the proposed freeze mechanism would add a more enforceable structural check.
The regulator has also proposed introducing an explicit provision to ensure that buybacks do not breach minimum public shareholding norms — a critical guardrail that prevents promoters from using buybacks to quietly increase their effective stake beyond permissible limits.
Operational Simplifications
On the operational side, SEBI has proposed removing the requirement for a separate trading window for buyback transactions, allowing such trades to be conducted through the normal market mechanism instead. It has also proposed dispensing with the requirement to display the company's identity as a purchaser on the trading screen — a move aimed at reducing market impact and information asymmetry during the buyback window.
Further, the regulator has proposed aligning the interval between two buyback offers with provisions under the Companies Act, 2013, bringing consistency between securities and corporate law frameworks.
Shareholder Communication Mandate
In a move toward greater transparency, SEBI has proposed making it mandatory for companies to send an intimation to shareholders through electronic mode regarding the buyback offer within one working day of the public announcement. This would ensure retail and minority investors are promptly informed rather than relying solely on exchange filings or media coverage.
The proposals are currently open for stakeholder feedback, and final guidelines are expected to be issued after SEBI's board review. The outcome will shape how Indian listed companies manage capital returns in the coming years.
Point of View
Time-bound, and trackable. The promoter freeze at the ISIN level is the most consequential element, closing a loophole where insiders could theoretically manoeuvre around existing transfer restrictions. What remains untested is enforcement — SEBI's track record on monitoring buyback compliance in real time has been patchy, and the removal of the identity-display requirement on trading screens could actually reduce transparency even as other measures add it. The real measure of this framework will be whether the front-loading rule produces genuine price support for minority shareholders or simply shifts the timing of token repurchases.

Frequently Asked Questions
What is SEBI's proposed new buyback framework?
SEBI has proposed reintroducing open-market buybacks through stock exchanges with a 66 working-day completion deadline, a requirement to deploy at least 40% of the buyback size in the first half of the offer period, and new safeguards including ISIN-level freezing of promoter shares. The proposals were developed in consultation with the Primary Market Advisory Committee (PMAC).
Why did SEBI reject the six-month buyback window suggested by PMAC?
SEBI argued that a six-month window could make buybacks irrelevant given how quickly market conditions change, and would make it difficult for shareholders to track the process. The regulator settled on 66 working days as a balanced timeline, also citing changes under the Finance Act, 2026 to the Companies Act regarding permissible gaps between buyback offers.
How does the proposed promoter share freeze protect minority shareholders?
SEBI may direct the freezing of shares and other specified securities held by promoters and their associates at the ISIN level during the buyback period. This builds on existing rules that bar promoters from dealing in company shares from the board decision date until the buyback closes, adding a more enforceable structural check.
What operational changes has SEBI proposed for buyback transactions?
SEBI has proposed removing the requirement for a separate trading window for buybacks, allowing trades through the normal market mechanism. It has also proposed dropping the requirement to display the company's identity as a purchaser on the trading screen, and mandating electronic shareholder intimation within one working day of a public announcement.
Will the new buyback rules affect public shareholding norms?
Yes. SEBI has proposed an explicit provision to ensure buybacks do not breach minimum public shareholding norms, preventing promoters from using repurchases to quietly increase their effective stake beyond permissible limits. The interval between two buyback offers will also be aligned with the Companies Act, 2013.
