The Supreme Court has dismissed curative petitions filed by telecom firms, including Vodafone Idea and Bharti Airtel, seeking recalculation of Adjusted Gross Revenue (AGR) dues amounting to Rs 1.43 trillion. The decision reaffirms the 2019 ruling that allows the Department of Telecommunications (DoT) to include non-telecom revenue in AGR calculations. Vodafone Idea's stock plummeted nearly 20% following the verdict, exacerbating its financial struggles due to significant debt, with analysts estimating it owes around Rs 700 billion in license fees and spectrum charges. Bharti Airtel, with stronger financials, is expected to face less impact. The court's ruling underscores the lengthy legal battle over AGR definitions and calculations, which has been ongoing since 2003.
