MUMBAI: Please note down the August 1, 2026 dateline, as the Securities and Exchange Board of India (SEBI) is streamlining corporate restructuring to protect minority stakeholders. Structural barriers to block market manipulation and enhance corporate transparency during equity allocations will come into force with implementation of the SEBI (Buy-Back of Securities) (Amendment) Regulations, 2026.
The new rules will change the way companies calculate limits for buy-backs. Under the updated guidelines, any listed company buying its own shares from the stock exchange will have to follow a strict limit.
The total buy-back amount must be less than 15% of the company’s total paid-up capital and free reserves. To prevent large corporate groups from finding loopholes, SEBI requires companies to calculate this 15% limit using both their standalone and consolidated financial statements.
In addition to these size limits, the amendment sets strict rules to stop insider trading. As soon as a company’s board passes a resolution or shareholders approve a buy-back via a postal ballot, all shares owned by the promoters and their associates are locked.
This lock happens directly at the International Securities Identification Number (ISIN) level. The shares remain frozen until the buy-back offer officially closes. However, if the company chooses a tender offer instead of buying from the stock exchange, the freeze is lifted temporarily. This exemption allows promoters to participate and sell their shares in the buy-back.
SEBI has now also fixed the time for an open-market buy-back. The offer must open within four working days of the public announcement, and it must close completely within 66 working days.
SEBI has made hiring external merchant bankers optional to help companies save on costs. If a company decides not to hire a merchant banker, the responsibility for compliance and reporting shifts entirely to three specific roles: the company’s internal Compliance Officer, its Statutory Auditor, and its Secretarial Auditor.
This regulatory overhaul shall enable listed corporate entities to execute buy-backs much faster and at a lower cost by making merchant bankers optional and shortening operational windows.
At the same time, forcing companies to apply the 15% cap across consolidated financials closes historical loopholes where cash could be hidden in subsidiaries.
Ultimately, the mandatory ISIN-level freeze on promoter shares effectively protects minority shareholders by preventing insiders from manipulating stock prices while the buy-back is live.
