This disclosure is made in compliance with SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, a standard procedure for significant personnel changes within listed entities.

Impact on Leadership Continuity

The death of a senior executive like an Executive Director can affect leadership continuity and operational oversight, especially given Mukherjee's recent appointment to the role.

His appointment was part of ONGC's broader effort in early 2026 to strengthen senior management with experienced internal talent.

What Changes Now

The company now faces a sudden vacancy in the crucial EO to Director HR role. ONGC will need to initiate a process to identify and appoint a successor for this position, highlighting the importance of robust succession planning within its senior management ranks.

Investor Focus and Risks

While the loss of an executive is a tragic personal event, investor attention will focus on potential disruptions to leadership continuity and the efficiency of the succession process. Key risks revolve around the company's ability to seamlessly fill the executive role.

Industry Context

Major Indian oil and gas public sector undertakings (PSUs) like Indian Oil Corporation Ltd (IOCL), Bharat Petroleum Corporation Ltd (BPCL), and Oil India Ltd (OIL) also regularly manage senior management transitions as part of their governance and operational continuity frameworks.
