Bharti Airtel's long-term credit rating has been upgraded by Crisil to 'Crisil AAA/Stable' from 'Crisil AA+/Positive', while its short-term rating was reaffirmed at 'Crisil A1+'. This upgrade reflects the company's significantly improved business and financial health in fiscal 2025. Strong revenue market share gains and healthy average revenue per user (ARPU) growth (up 17% to ₹245) drove a 21% jump in operating profit to ₹94,733 Cr. Financially, net leverage improved to 2.1x (from 2.5x) due to robust earnings and internal accruals funding capex, reducing reliance on external debt. This top-tier rating should enhance investor confidence and potentially lower borrowing costs, providing greater strategic flexibility.
