This disclosure is a regulatory filing submitted to BSE Limited and the National Stock Exchange of India Limited under SEBI Listing Regulations (Regulation 30). It provides a further update on a matter concerning the company's Kenyan subsidiary, Tata Chemicals Magadi Limited (TCML).

The filing is a continuation of previous disclosures made on July 29, 2026, and September 9, 2026, regarding a Notice received by TCML from the Ministry of Mining, Blue Economy and Maritime Affairs, Kenya, dated July 28, 2026.

The key development is that the High Court of Kenya has passed an order dated October 23, 2026. The order states that the court has no jurisdiction over the dispute and, therefore, cannot take any further steps on the matter.

TCML is currently examining this court order. The company states that TCML will take legal and all other necessary steps to determine a way forward.

Concurrently, a committee led by the Principal Secretary for Mining (on behalf of the Ministry) and the Chief Executive Officer of TCML is undertaking a detailed technical review of all matters. This committee is expected to submit a report to the office of the Cabinet Secretary for consideration. The purpose of this review is to establish a sustainable framework that promotes responsible mining, value addition, community development, and mutually beneficial partnerships.

The disclosure does not quantify any financial impact of this development on Tata Chemicals Limited.
