Hindustan Aeronautics Limited (HAL) has undergone a significant, yet quiet, transformation, shifting from a license producer to an innovative designer. With a robust order book exceeding ₹2.5 lakh crore, strong revenue of ₹32,105 crore and profit of ₹8,469 crore, and consistent operating margins over 20%, HAL is now a deep-tech defence powerhouse. Despite its strong financial performance and capabilities in areas like avionics and flight-control algorithms, its valuation metrics suggest it remains an undervalued asset in the defence sector, offering significant potential for investors.
