Shankara Building Products has launched a mandatory open offer to acquire a 26% stake in the company at ₹150 per share. The offer, initiated by The Ballygunge Family Trust along with persons acting in concert (PACs), aims to rectify past non-compliances with SEBI’s Substantial Acquisition of Shares and Takeovers (SAST) Regulations.
The tendering period begins on September 7, 2026, and closes on September 21, 2026. The acquirer intends to purchase up to 63,04,825 equity shares from public shareholders. This acquisition will increase the promoter group’s stake from 49.52% to 75.52%, assuming full acceptance of the offer.
Offer Details and Timeline
The open offer is not subject to any minimum level of acceptance. Shareholders can tender their shares through the stock exchange mechanism on the BSE, which serves as the designated exchange for the transaction. Nikunj Stock Brokers Limited acts as the buying broker for the offer.
| Key Dates | Details |
|---|---|
| Public Announcement Date | July 15, 2026 |
| Letter of Offer Dispatch | August 31, 2026 |
| Offer Opening Date | September 7, 2026 |
| Offer Closing Date | September 21, 2026 |
| Completion Date | October 6, 2026 |
Financial Arrangements
The total fund requirement for the open offer, assuming full acceptance, is ₹94.57 crore. The acquirer has deposited ₹23.64 crore, representing 25% of the maximum consideration, into an escrow account with Kotak Mahindra Bank Limited. The remaining funds will be financed through the internal resources of the acquirer and PACs.
What the Numbers Show
The offer price of ₹150 per share is significantly higher than the volume-weighted average price (VWAP) of ₹116.80 paid by the acquirer during the 52 weeks preceding the public announcement. This premium reflects the regulatory requirement to include interest for the delay in making the public announcement, as well as the highest price paid during the relevant periods under SEBI SAST regulations.
Background of the Acquisition
The Ballygunge Family Trust initiated share acquisitions in February 2026, triggering a breach of Regulation 4 of the SEBI SAST Regulations. Consequently, the acquirer was obligated to make an open offer to public shareholders. The offer is designed to consolidate the promoter group’s holding while ensuring compliance with regulatory norms regarding public shareholding limits.
