Indo Borax buys 64.26% of Kronox for ₹246 cr in 2026

Deal snapshot and why it matters

Indo Borax & Chemicals Ltd has approved an acquisition that takes it into specialty fine chemicals through the purchase of a controlling stake in Kronox Lab Sciences Ltd. The board cleared the share purchase agreement on August 20, 2026, according to the disclosure. The transaction values the promoter stake purchase at an aggregate consideration of ₹246.12 crore.

Because the acquisition crosses the SEBI takeover threshold, it also triggers a mandatory open offer to Kronox’s public shareholders. The open offer is priced higher than the negotiated promoter block price, reflecting the SEBI (Substantial Acquisition of Shares and Takeovers) Regulations, 2011 (SAST). Indo Borax has stated the move is aimed at diversifying its portfolio into high-growth specialty chemicals.

What Indo Borax is buying

Under the share purchase agreement, Indo Borax will acquire 64.26% of Kronox’s equity shares. The purchase consists of 2.38 crore equity shares to be bought from the promoter selling shareholders. The sellers named in the disclosure are Ketan Vinodchandra Ramani, Pritesh Vinodchandra Ramani, and Jogindersingh Gianchand Jaswal.

The negotiated price for the promoter shares is ₹103.22 per share. The disclosure also includes a footnote on an “effective price” calculation under Regulation 8(7) of the SAST Regulations. While the SPA price is ₹103.22, the effective price inclusive of consultancy fees payable by Kronox to the sellers under transition support arrangements is stated as ₹105.87 per share.

Zenrock Chemicals joins as person acting in concert

Zenrock Chemicals Private Limited (ZCPL) is participating in the Kronox acquisition as a person acting in concert (PAC) with Indo Borax. The disclosure explicitly identifies ZCPL’s role in the transaction structure alongside Indo Borax.

The inclusion of a PAC is relevant in takeover disclosures because thresholds, disclosures, and offer obligations are assessed on an acquirer plus PAC basis under SAST. In this case, Indo Borax and ZCPL together will be responsible for making the open offer to Kronox’s public shareholders.

Mandatory open offer triggered under SEBI SAST rules

The acquisition grants Indo Borax control and voting rights exceeding 25% of Kronox’s share capital, which triggers a mandatory open offer under the SAST Regulations. Indo Borax, along with ZCPL, will make an open offer to acquire up to 95.7 lakh equity shares. This represents approximately 25.79% of Kronox’s voting share capital.

The open offer price for public shareholders is set at ₹157.27 per equity share. The disclosure notes that the offer price has been determined in accordance with SAST regulations. The entire consideration for both the promoter block purchase and the open offer will be paid in cash through electronic transfer.

Background: Zenrock’s earlier open offer for Indo Borax

The provided text also references a separate takeover process involving Indo Borax itself earlier in 2026. Zenrock Chemicals Private Limited, along with PACs, completed an open offer for Indo Borax & Chemicals Limited. That open offer opened on April 10, 2026, and closed on April 24, 2026, with an offer price of ₹256.30 per equity share.

As disclosed, 24,44,934 shares were tendered by public shareholders and all were accepted. The total consideration stated for that acceptance is ₹62,65,34,064.20. After completion, the combined shareholding of the acquirer and PACs increased to 1,87,44,764 equity shares, representing 58.41% of the expanded voting share capital, while public shareholders held 41.59% (1,33,45,236 equity shares).

Market impact and what investors can track from here

The transaction structure matters for shareholders of Kronox because the change in control triggers an open offer, and the offer price is explicitly disclosed at ₹157.27 per share. For Indo Borax shareholders, the key disclosed elements are the cash nature of the consideration and the three-month completion expectation.

The text also notes that Indo Borax shares had “plunged sharply” in connection with the earlier change in control and compulsory open offer process, though no percentage move is provided. For investors following the current Kronox transaction, the next factual milestones will come through the public announcement process and subsequent open offer timetable, alongside any completion confirmation within the stated three-month window.

Conclusion

Indo Borax’s board-approved acquisition of 64.26% of Kronox for ₹246.12 crore sets up a mandatory open offer for up to 25.79% of Kronox at ₹157.27 per share, with payments to be made in cash via electronic transfer. The company has indicated a three-month completion timeline and stated that no governmental or regulatory approvals are required. The next confirmed steps to watch are the public announcement and the formal open offer process for Kronox shareholders.
