India's corporate landscape is gearing up for a significant phase of capital investment, with companies projected to double their spending to around $850 billion over the next five years. This surge is driven by sectors like power transmission, aviation, and green hydrogen, with the 100 largest publicly listed companies expected to play a key role in financing the capex internally. With sound balance sheets and government support, companies are anticipated to grow without taking on substantial new debt. Key sectors like power and transmission, aviation, and core industries are poised to benefit from this investment wave, with major players such as NTPC, Tata Power, and Power Grid Corporation leading the way. Additionally, high-growth sectors like green hydrogen and semiconductors are set to attract significant investments. Companies like the Adani Group and Tata Group have outlined ambitious investment plans, focusing on sectors like aviation and electronics. While the outlook is positive, potential credit risks have been flagged in sectors such as renewables and steel due to execution hurdles and pricing volatility.
