Kronox Lab Sciences Open Offer: ₹157.27 Price in 2026

Kronox Lab Sciences and the latest open offer update

Kronox Lab Sciences Ltd, incorporated in 2008, manufactures high purity fine inorganic chemicals, phosphate, and metallic chemicals. The company has disclosed a regulatory update after Indo Borax and Chemicals Limited published a Detailed Public Statement (DPS) for a mandatory open offer in Kronox Lab Sciences. The DPS lays out the formal terms under which public shareholders may tender their equity shares into the offer.

The open offer is being made under the SEBI (Substantial Acquisition of Shares and Takeovers) Regulations, 2011. As described in the filings, the announcement is primarily a procedural and regulatory step and does not include any financial performance disclosures. Still, it matters because it sets a defined price, size, and timetable for tendering shares.

Detailed Public Statement (DPS): what it formally establishes

The DPS was published on August 28, 2026, across multiple newspapers, including Financial Express (English), Jansatta (Hindi), Navshakti (Marathi), and Lokshatta-Jansatta (Gujarati). The statement formalises the key terms of the mandatory open offer and provides the framework for the next steps, including SEBI filings, dispatch of the Letter of Offer, and the tendering window.

A key point for shareholders is that the DPS is the document that sets out the offer terms in a standardised format and triggers the operational timeline for the open offer process. The public announcement for the offer was issued on August 20, 2026.

Parties to the transaction: acquirer, PAC, and manager

Indo Borax and Chemicals Limited is the acquirer for the open offer. Zenrock Chemicals Private Limited is identified as a person acting in concert (PAC) with the acquirer. The open offer is being managed by IIFL Capital Services Limited, which published the DPS on August 28, 2026.

Kronox Lab Sciences stated that the disclosure is made under Regulation 14(3) of the SEBI SAST Regulations, 2011, and Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015.

Offer size and price: the two headline numbers

The open offer seeks to acquire up to 95,70,000 equity shares of Kronox Lab Sciences. This represents 25.79% of the target company’s voting share capital, as stated in the DPS. The offer price is fixed at ₹157.27 per equity share.

The payment mode specified is cash. The filings also state that, assuming full acceptance, the total consideration payable under the open offer would be ₹1,505 crore.

Key terms at a glance

Open offer timeline: dates investors must track

The timeline also includes September 4, 2026, as the last date for filing the Draft Letter of Offer with SEBI. Indo Borax is required to communicate acceptance or rejection of tendered shares by November 13, 2026.

Market reaction: Kronox shares rally after the filing

Following the regulatory filing on the BSE about the open offer, shares of Kronox Lab Sciences rallied over 10% to Rs 205.75 on the BSE on Friday, as reported in the provided text. This market move came after investors assessed the disclosed transaction structure and the open offer terms.

The offer price disclosed in the DPS is ₹157.27 per share, while the reported traded price cited in the same context is Rs 205.75. The disclosure and subsequent trading highlight how corporate control transactions and open offer announcements can influence near-term price action, even when the update itself is described as procedural.

Deal structure: 64.26% acquisition and post-transaction promoter holding

The disclosed details also state that Indo Borax will acquire a 64.26% stake in Kronox Lab Sciences along with Zenrock Chemicals as PAC. The open offer component is for up to 25.79% of the voting share capital through acquisition of up to 95.7 lakh shares.

The filings further note that post-transaction, Kronox Lab Sciences’ erstwhile promoters will continue to hold a 9.95% stake and provide transition support. Separately, it is stated that following the acquisition, Indo Borax & Chemicals will acquire control and voting rights of 25.79% of the voting share capital of Kronox Lab Sciences.

Why this matters for public shareholders

For public shareholders, the practical decision point is whether to tender shares at the offer price of ₹157.27 during the tendering window from October 15 to October 29, 2026. The Letter of Offer, scheduled for dispatch by October 8, 2026, is the key document that shareholders typically rely on for the complete operational details of tendering.

The stated timeline also clarifies when shareholders can expect a decision on their tendered shares. Indo Borax is required to communicate acceptance or rejection by November 13, 2026, which sets expectations for post-tender confirmation.

Stated rationale and regulatory framing

As per the provided regulatory filing context, the acquisition is described as part of a long-term strategy to diversify the company’s portfolio by investing in sectors that demonstrate stability and growth potential. The open offer itself is framed as a mandatory open offer under the SEBI SAST Regulations, 2011, pursuant to Regulation 3(1) and Regulation 4.

This regulatory framing is important because it indicates the offer is tied to control and shareholding thresholds under SEBI rules, rather than being a discretionary buyback-like action by the target company.

What happens next

The next formal steps include filing the Draft Letter of Offer with SEBI by September 4, 2026, followed by dispatch of the Letter of Offer by October 8, 2026. The tendering period is scheduled to run from October 15 to October 29, 2026.

After the tendering closes, Indo Borax must communicate acceptance or rejection of tendered shares by November 13, 2026. Investors tracking Kronox Lab Sciences will likely focus on these dates and the final outcome of the open offer process as it progresses under the SEBI-defined timetable.
