New Delhi: Fortis Healthcare Limited on Thursday informed stock exchanges that its promoter shareholder, Northern TK Venture Pte Ltd (NTK), has filed a petition before the Tokyo District Court seeking to amend its ongoing claim against Japan’s Daiichi Sankyo Company Limited.

NTK is an indirect wholly owned subsidiary of Malaysia-based IHH Healthcare Berhad, the parent company of Fortis’ promoter group. The latest development forms part of a protracted legal dispute linked to IHH’s 2018 investment in Fortis and subsequent open offers.
According to an announcement released by IHH to the Bursa Malaysia and Singapore exchanges, NTK submitted a Petition to Amend Claims on February 12, 2026, which was delivered to Daiichi Sankyo by the court on February 17.
The amendment primarily seeks to broaden the scope of the injunctive relief earlier sought. While the original claim requested the court to restrain Daiichi Sankyo from allegedly obstructing the open offers through defamatory statements to the Securities and Exchange Board of India (SEBI) and others, the revised petition seeks to prevent any obstruction to future acquisition of shares, investments or corporate exercises relating to Fortis and Fortis Malar Hospitals.
The damages claim, first announced in November 2023 and May 2025, remains unchanged. NTK had sought damages of INR109.29 billion (over ₹10,900 crore) for alleged tortious losses, apart from a separate defamation claim and accrued interest. It had also sought directions for publication of statements to vindicate its reputation.
The open offers for Fortis and Fortis Malar were completed on November 10, 2025. Following this, NTK moved to amend the injunctive claim to reflect the current position and to cover future transactions involving the two hospital chains.
Fortis said it will inform exchanges of any further material developments in the matter.
The dispute traces its roots to Daiichi Sankyo’s long-running litigation linked to the erstwhile promoters of Fortis, and has cast a legal overhang on IHH’s investment in the hospital operator. The outcome of the Tokyo proceedings could have implications for the promoter’s strategic flexibility in Fortis and related entities going forward.
