ADAG stands for the Reliance Anil Dhirubhai Ambani Group, a major Indian multinational conglomerate that was formed following the 2005 family business split of the original Reliance empire between brothers Mukesh Ambani and Anil Ambani. At its peak, the ADAG umbrella encompassed a massive portfolio of high-profile enterprises operating across diverse and critical sectors, including telecommunications through Reliance Communications, financial services through Reliance Capital, infrastructure development through Reliance Infrastructure, and power generation through Reliance Power. However, due to significant debt burdens, shifting regulatory landscapes, and intensive macroeconomic challenges over subsequent years, many of the group's core companies underwent massive corporate restructuring, asset sales, and legal bankruptcy resolution processes, dramatically altering its operational scope and corporate structure.
