Is Bharti Airtel overvalued or undervalued?

As of 12 November 2025, the valuation grade for Bharti Airtel has moved from fair to expensive, indicating that the company is currently overvalued. The key ratios reflect this assessment, with a PE ratio of 37.56, an EV to EBITDA of 12.54, and a PEG ratio of 0.31, which suggests that the stock may not be justified at its current price level given its growth prospects.
In comparison to its peers, Bharti Airtel's valuation appears high, especially when contrasted with Vodafone Idea, which has a PE ratio of 18.33, and Tata Communications, which, while attractive, has a significantly higher EV to EBITDA of 14.22. Despite Bharti Airtel's strong ROE of 26.72% and ROCE of 19.64%, the overall valuation metrics suggest that the stock is overvalued relative to its peers. Additionally, while Bharti Airtel has outperformed the Sensex over the past year with a return of 33.29% compared to the Sensex's 7.36%, this performance does not mitigate the concerns regarding its current valuation.
