The Maharatna status is the highest designation granted by the Government of India to its most strategically important and financially powerful Central Public Sector Enterprises. Maharatna companies possess the maximum financial and operational autonomy, with the power to invest up to Rs 5,000 crore or 15 percent of their net worth — whichever is higher — in a single project without seeking government approval, and can make global investments and restructuring decisions independently. As of 2026, there are 14 Maharatna companies in India, with Hindustan Aeronautics Limited being the 14th and most recently elevated. According to market capitalisation data as of May 30 2026, HAL, NTPC, and ONGC are the top three Maharatna companies by market cap.
