Dear Madam, Sirs,

Sub: Disclosure under Regulations 30 and 51 of Securities and Exchange Board of India (Listing Obligations and Disclosure Requirements) Regulations, 2015

This has reference to our earlier disclosures dated June 29, 2025 and December 19, 2025.

Background:

Tata Steel Limited (the 'Company') had earlier informed that it has received a show cause cum demand notice ('SCN') dated June 27, 2025 from the Office of the Commissioner (Audit), Central Tax, Ranchi, proposing disallowance of Input Tax Credit in contravention of the provisions of Section 74(1) of the Central Goods and Services Tax Act, 2017/State Goods and Services Act, 2017 read with Section 20 of the Integrated Goods and Services Tax Act, 2017, for the period FY2018-19 through FY2022-23.

The SCN required the Company to show cause before the Additional/Joint Commissioner of Central GST & Central Excise, Jamshedpur, Jharkhand as to why the Goods and Service Tax ('GST') amounting to ₹1007,54,83,342/- along with interest/penalty, if any, shall not be demanded and recovered from the Company. Of the aggregate GST amount demanded, the Company had already paid GST of ₹514,19,36,211/- in the normal course of business and therefore the alleged GST exposure was of ₹493,35,47,131/- only. Further, the Company made its detailed submissions before the appropriate forum within the given timelines as per the said SCN.

Subsequently, on December 19, 2025, the company had informed receipt of Adjudication Order from the Commissioner of CGST & Central Excise, Jamshedpur, Jharkhand, on December 18, 2025, directing the payment of tax amounting to ₹493,35,47,131, penalty of ₹638,82,62,185 and appropriate interest on the total amount of tax.

Present Status:

The Company has evaluated the Order passed by Commissioner of CGST & Central Excise, Jamshedpur, Jharkhand, and it believes that proper cognizance of the submissions made by the Company was not taken while adjudicating the matter. Further the Company believes that it has a good case on merits and hence, has filed a Writ Petition before the Hon'ble High Court of Jharkhand on March 11, 2026, challenging the Order passed by Commissioner of CGST & Central Excise, Jamshedpur, Jharkhand dated December 18, 2025, and seeking quashing of the Order.

The Company was reviewing its disclosure obligations and hence, this disclosure is being made even date.

This disclosure is being made by the Company in compliance with Regulations 30 and 51 of the Securities and Exchange Board of India (Listing Obligations and Disclosure Requirements) Regulations, 2015, as amended.
