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

Deal snapshot: control acquisition in specialty chemicals

Indo Borax & Chemicals Ltd has approved the acquisition of a controlling stake in Kronox Lab Sciences Ltd, a specialty fine chemicals manufacturer. The board cleared the transaction on August 20, 2026, through a share purchase agreement (SPA). Indo Borax will acquire 64.26% of Kronox’s equity shares for an aggregate consideration of ₹246.12 crore. The acquisition is positioned as a move to diversify Indo Borax’s portfolio into higher-growth specialty chemicals. Kronox reported FY26 turnover of ₹101.22 crore, as disclosed. The transaction is structured as a cash deal, with payments to be made via electronic transfer.

Board approval and the structure of the SPA

The SPA involves Indo Borax purchasing 2.38 crore equity shares of Kronox from the promoter sellers. The identified sellers are Ketan Vinodchandra Ramani, Pritesh Vinodchandra Ramani, and Jogindersingh Gianchand Jaswal. The agreed purchase price under the SPA is ₹103.22 per share. A footnote in the disclosure adds that, for regulatory calculation purposes, the effective price inclusive of consultancy fees payable by Kronox to the sellers under transition support arrangements is ₹105.87 per share. This effective price is stated as being calculated under Regulation 8(7) of the SEBI (Substantial Acquisition of Shares and Takeovers) Regulations, 2011.

Zenrock Chemicals as person acting in concert

Zenrock Chemicals Private Limited (ZCPL) is participating as a person acting in concert with Indo Borax for the acquisition. The disclosure frames the acquisition as one that confers control and voting rights beyond the 25% threshold. As a result, it falls under the mandatory open offer provisions of the SEBI takeover rules. The presence of a person acting in concert is explicitly stated in the transaction description.

Mandatory open offer: price, size, and threshold trigger

Because the acquisition results in Indo Borax crossing the control and voting rights threshold, it triggers a mandatory open offer under the SAST Regulations. Indo Borax, along with ZCPL, will make an open offer to public shareholders to acquire up to 95.7 lakh equity shares. This represents approximately 25.79% of Kronox’s voting share capital, according to the disclosure. The open offer price is set at ₹157.27 per equity share, with the company stating it has been determined in accordance with SAST regulations. The consideration for both the private agreement and the open offer will be paid in cash via electronic transfer.
