Reliance Group

Overview

Reliance Group, also known as Reliance Anil Dhirubhai Ambani Group (Reliance ADAG or Reliance ADA Group), is an Indian conglomerate headquartered in Mumbai, Maharashtra. The group operates across sectors including financial services, power, infrastructure, telecommunications, defence, and entertainment. It was constituted in 2006 following the division of the assets of the original Reliance Industries founded by Dhirubhai Ambani, with the constituent companies of this group placed under the chairmanship of his younger son, Anil Ambani.

Key facts

Background

The roots of Reliance Group lie in the business empire built by Dhirubhai Ambani, who founded Reliance Commercial Corporation in the 1960s and grew it into Reliance Industries, one of India's largest private-sector enterprises. After Dhirubhai Ambani's death in July 2002, a dispute over control of the group emerged between his sons, Mukesh Ambani and Anil Ambani.

In June 2005, the family announced a settlement brokered with the involvement of their mother, Kokilaben Ambani. Under this arrangement, the elder son Mukesh Ambani retained Reliance Industries Limited and the petrochemicals, refining and oil and gas businesses, while Anil Ambani took charge of the telecommunications, power, financial services and entertainment businesses, which were subsequently consolidated under the Reliance Anil Dhirubhai Ambani Group.

Constituent companies

Several listed and unlisted entities have operated under the Reliance Group umbrella, including:

• Reliance Communications – telecommunications operator.
• Reliance Capital – diversified financial services company, with subsidiaries in asset management, insurance and lending.
• Reliance Infrastructure – engineering, procurement and construction company involved in power transmission, roads and metro rail projects, including the Mumbai Metro Line 1.
• Reliance Power – power generation company developing thermal, hydro and renewable projects.
• Reliance Naval and Engineering – shipbuilding and defence engineering company (formerly Pipavav Defence and Offshore Engineering).

Significance

The creation of the Reliance Group represented one of the largest corporate restructurings in Indian business history, formally separating the businesses built under the Ambani family name into two distinct conglomerates. In its early years, the group was associated with rapid expansion in telecommunications, power generation and infrastructure, contributing to the broader liberalisation-era growth of private enterprise in India. Several of its companies have subsequently faced significant financial stress and insolvency proceedings, which have been the subject of considerable attention in Indian corporate and regulatory discussion.
