Fitch Ratings on Wednesday projected aggregate revenue for rated corporates to rise by 9 per cent in the current fiscal, stronger than the 5 per cent estimated for FY26, which would keep credit metrics of Indian companies stable. Fitch, however, said that some corporates could be vulnerable to a re-escalation of hostilities between the US and Iran, which could push up oil prices, fuel marketing losses and raise working capital needs at oil refining and marketing companies, pressuring free cash flow.
