The DPS was published on August 28, 2026. The open offer is being made under the SEBI (Substantial Acquisition of Shares and Takeovers) Regulations, 2011.

Offer size, stake and price: what shareholders are being offered

The headline term for shareholders is the offer price of ₹157.27 per share. Indo Borax intends to buy up to 95.7 lakh shares, equivalent to 25.79% of the target’s voting capital. The structure described is a mandatory open offer, which is typically triggered when an acquirer crosses prescribed control or voting thresholds. The DPS states that valid tenders during the offer period will receive ₹157.27 per share. The mode of payment is stated as cash. The DPS and related write-ups also refer to the offer as part of a broader acquisition that results in Indo Borax obtaining control.

Who is involved: acquirer, PAC and manager to the offer

The DPS states that Indo Borax and Chemicals Limited is the acquirer. Zenrock Chemicals Private Limited is named as a person acting in concert (PAC) alongside the acquirer. IIFL Capital Services Limited is acting as the manager to the open offer and published the DPS on August 28, 2026. The regulatory basis is explicitly mentioned as the SEBI SAST Regulations, 2011, including references to Regulation 3(1) and Regulation 4 in the provided text. These roles matter because the manager coordinates the process and timelines, while the PAC relationship clarifies how the acquisition is evaluated under takeover rules. The DPS publication formalises the mandatory open offer process for Kronox Lab Sciences at the stated price and size.

Key dates investors should track

The tendering period is scheduled to open on October 15, 2026 and close on October 29, 2026. The last date for dispatch of the Letter of Offer to public shareholders is October 8, 2026. Indo Borax is required to communicate acceptance or rejection of tendered shares by November 13, 2026. The timeline also includes September 4, 2026 as the last date for filing the Draft Letter of Offer with SEBI. These dates define the practical window for shareholder action and the post-tender confirmation cycle. Investors typically use the Letter of Offer to review process details, tender mechanics, and other statutory disclosures.

How the mandatory open offer was triggered

The text states that Indo Borax & Chemicals has acquired a 64.26% stake in Kronox Lab Sciences, which triggered the mandatory open offer for public shareholders. The company’s Board of Directors, in a meeting held on August 20, 2026, approved the execution of a share purchase agreement to acquire 64.26% of Kronox’s equity shares. The aggregate consideration for this promoter stake purchase is stated as ₹246.12 crore. The transaction involves buying 2.38 crore equity shares from promoters named in the text: Ketan Vinodchandra Ramani, Pritesh Vinodchandra Ramani, and Jogindersingh Gianchand Jaswal. The promoter transaction price is stated as ₹103.22 per share. The same set of details notes that the acquisition results in Indo Borax crossing control and voting rights thresholds, making the open offer mandatory under the takeover regulations.

Consideration: ₹150.5 crore vs ₹150.51 crore vs ₹1,505 crore

Multiple consideration figures are cited across the provided material for the open offer, and they do not all match. One section states the maximum consideration for the open offer is ₹150.5 crore. Another line provides a precise rupee figure of ₹1,50,50,73,900, which is also stated as ₹150.51 crore. Separately, one headline and a table in the supplied text state that, assuming full acceptance, the total consideration payable under the open offer will be ₹1,505 crore. Based on the same text, the offer size is 95,70,000 shares at ₹157.27 per share, while the consideration numbers appear in different places with different magnitudes. Given the inconsistency, readers should treat the ₹1,505 crore figure as a conflicting claim within the supplied material and rely on the DPS/Letter of Offer for the final payable amount. The payment mode is consistently stated as cash, and the transfer is mentioned as electronic for the overall transaction consideration.

What this means for public shareholders

For public shareholders, the operational decision is whether to tender shares during the October 15 to October 29, 2026 window. The DPS states that shareholders who tender validly will be offered ₹157.27 per share. The acceptance or rejection communication date of November 13, 2026 sets expectations on when tender outcomes will be known. The Letter of Offer dispatch deadline of October 8, 2026 is important because it typically contains the final procedural details for tendering. The open offer stake is capped at 25.79% of voting capital, which means acceptance may be on a proportionate basis if tenders exceed the offer size. The stated cash payment mode clarifies that consideration is not in shares or other instruments. The presence of a manager to the offer, IIFL Capital Services, signals that the process will follow standard tendering and settlement mechanisms outlined under takeover regulations.

Why the development matters for control and compliance

The acquisition of 64.26% is described as granting Indo Borax control, which is why the mandatory open offer requirement becomes relevant. The open offer is presented as part of compliance under the SEBI SAST framework when control thresholds are crossed. The fact that the promoter purchase price is stated at ₹103.22 per share while the open offer price is ₹157.27 per share is a notable disclosed data point in the material. The open offer provides an exit opportunity to public shareholders at the specified price under the stated regulations. At the same time, the inconsistency in total consideration figures appearing in the supplied text highlights why investors typically wait for the final Letter of Offer and SEBI-filed documents for definitive payable totals. The next key confirmed step in the process, as provided, is the filing of the Draft Letter of Offer with SEBI by September 4, 2026 and the subsequent dispatch of the Letter of Offer by October 8, 2026.
