Eris Lifesciences COO resignation: Krishnakumar Vaidyanathan stepped down as Executive Director and Chief Operating Officer with effect from the close of business hours on September 30, 2026, according to the company's October 5, 2026, BSE filing. The company submitted his resignation letter as a follow-up to its earlier disclosure.

Vaidyanathan said he was leaving to pursue professional opportunities outside the company. His letter, dated September 11, 2026, covered both his executive directorship and his position as COO. It did not identify a prospective employer or specify the nature of those opportunities.

The October 5 submission enclosed the letter for exchange information and records, referring to the company's previous intimation dated September 11, 2026. The effective departure date therefore preceded the latest filing.

Resignation accepted with notice period waived

In his letter to the board of directors, Vaidyanathan asked the company to accept and record his resignation, waive the applicable notice period and complete the necessary formalities. He also expressed gratitude to the directors for the support and cooperation extended during his tenure.

The enclosed document carries an endorsement stating that the resignation was accepted with waiver of notice period. Milind Talegaonkar, Company Secretary and Compliance Officer, signed the acceptance on behalf of Eris Lifesciences. The document does not specify the length of the notice period waived.

The supplied filing provides no details of a successor, an interim appointment or a reassignment of the COO's responsibilities. Its disclosure concerns Vaidyanathan's departure and the accompanying resignation letter.

Eris Lifesciences addressed the submission to both BSE Limited and the National Stock Exchange of India Limited. It identified the company's BSE security code as 540596 and its NSE symbol as ERIS.
