Vedanta Soars After Demerger Approval

The demerger will split the metals-to-oil conglomerate into separate entities focusing on aluminium, oil and gas, ferrous, power, and steel. This move aims to streamline operations, enhance management focus, and unlock shareholder value.

Vedanta's spokesperson stated that the approval marks a key milestone in the company's transformation into focused, sector-leading companies.
