Regulatory Compliance

Ms. Grover has been confirmed as not debarred from holding the office of Director by SEBI, the Ministry of Corporate Affairs, or any other statutory authority. The detailed disclosure, including her brief profile as required under Part A of Para A of Schedule III of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, has been made available on the Company's website at www.hoec.com .

Hindustan Oil Exploration Company Limited has received an administrative warning letter from the Securities and Exchange Board of India (SEBI) on May 4, 2026, for delayed compliance with disclosure obligations under the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015 (LODR Regulations). The warning was communicated via email at 14:59 IST and was disclosed to the stock exchanges by the company on May 5, 2026, pursuant to Regulation 30 of the Listing Regulations.

Background: Interim Orders and Disclosure Obligation

The matter relates to interim orders passed by the Hon'ble High Court of Madras concerning a foreign arbitral award. SEBI noted that the High Court passed ad-interim orders on September 16, 2025, and October 28, 2025. The ad-interim order dated September 16, 2025, was granted until October 7, 2025. Subsequently, an interim order was passed on October 28, 2025, directing the company to furnish a Bank Guarantee of ₹15.12 crore, which is to remain in force until final orders are passed in the pending proceedings before the Gujarat High Court.

SEBI observed that the mandated Bank Guarantee amount of ₹15.12 crore exceeded the applicable materiality threshold of the company under Regulation 30(4)(c) of the LODR Regulations, thereby making timely disclosure mandatory.

Nature of the Violation

The key regulatory concern cited by SEBI was the significant delay in disclosing the October 28, 2025 interim order. The disclosure was filed with the exchanges only on January 19, 2026—a delay of 83 days—and only after intervention by SEBI and the Exchange. This was found to be in violation of Regulation 30(6) and 30(7), which mandate that listed entities provide regular updates on material developments until the event is resolved or closed.

The following table summarises the key details of the regulatory action:
