The combined fixed assets of 702 companies in the Business Standard sample climbed to ₹37.78 trillion at the end of September 2025, from ₹33.41 trillion a year earlier and ₹36.33 trillion at the end of March 2025. By comparison, fixed assets, seen as a proxy for capex, had grown 7.9 per cent Y-o-Y in H1FY25 and 6.9 per cent in H2FY25. The capex acceleration in H1FY26 was driven by capital-intensive sectors such as cement, power, construction and infrastructure, mining and metals, and automobiles.
Grasim Industries emerged as the single largest contributor to capex growth, followed by Adani Enterprises, NTPC, Tata Steel and Power Grid Corporation. Together, these five companies accounted for nearly 30 per cent of total capex within the sample.
Grasim’s consolidated fixed assets rose 30 per cent Y-o-Y to ₹1.25 trillion at the end of September 2025, from about ₹96,500 crore a year earlier. The expansion was largely led by its listed cement arm, UltraTech Cement, which saw its fixed assets jump 41.2 per cent Y-o-Y in H1FY26 to around ₹95,500 crore, reflecting the completion of its acquisition of Kesoram Industries’ cement assets and the commissioning of new projects.
Adani Enterprises reported a 25.2 per cent Y-o-Y increase in fixed assets to ₹1.42 trillion by the end of H1FY26. NTPC’s fixed assets rose 8 per cent to ₹3.82 trillion as of September 2025, while Tata Steel and Power Grid Corporation posted Y-o-Y capex growth of 13.6 per cent and 7.5 per cent, respectively, in the first half of the current financial year.
For many individual companies, acquisitions were a key driver of fixed asset growth in the first half. This was evident among firms such as UltraTech Cement, Adani Ports, Dr Reddy’s Laboratories, Coromandel International, JSW Energy and Tata Consumer Products.
The pace of corporate capex was even stronger -- at 20 per cent Y-o-Y -- when oil and gas companies such as Reliance Industries, Indian Oil Corporation and Oil & Natural Gas Corporation (ONGC) are included.
Total fixed assets of non-financial companies, including oil and gas, rose 20 per cent Y-o-Y to ₹60.8 trillion at the end of September 2025, up from ₹50.65 trillion a year earlier and ₹54.72 trillion at the end of March 2025.
Indeed, incremental capex by 14 oil and gas companies amounted to ₹5.78 trillion in H1FY26, exceeding the combined capex of all other listed non-financial companies. On a Y-o-Y basis, fixed asset additions by the 702 listed companies excluding BFSI and oil & gas stood at ₹4.36 trillion in H1FY26.
Reliance Industries dominated the capex cycle. Its fixed assets surged 84.2 per cent Y-o-Y to ₹12.89 trillion in H1FY26, from around ₹8.1 trillion a year earlier. The company added roughly ₹4.9 trillion to its asset base over the period -- more than any other firm -- accounting for 48 per cent of total capex by all non-BFSI companies in the sample.
The sharp expansion in Reliance’s asset base was led by its newer businesses, including media, broadcasting, entertainment and new energy ventures, followed by its oil-to-chemicals operations.
Overall, the numbers suggest that corporate capex gathered momentum in H1FY26 despite a slowdown in topline growth and a decline in capacity utilisation, as measured by the ratio of revenues to fixed assets. As a result, the net sales-to-fixed-assets ratio fell to a two-and-a-half-year low of 167.9 per cent in H1FY26, from 180.6 per cent in H1FY24 and a decade-high 181.2 per cent in H1FY23. The ratio is calculated using annualised net sales and fixed assets at the end of the respective half-year period.
According to analysts, any further decline in the net sales-to-fixed-assets ratio could dampen incentives for companies to step up investment in fresh capex.
