IDFC First Bank, a private lender in India, reported a 4.9% year-on-year increase in standalone net profit for the fourth quarter of FY26, amounting to ₹319 crore, compared to ₹304 crore in the same quarter last year. The bank's normalized profit after tax (PAT) was ₹746 crore, excluding one-time items such as a fraud incident and treasury losses. Net interest income surged by 15.7% to ₹5,677 crore, driven by a 12.1% increase in interest income, which reached ₹10,552.8 crore. However, the pre-provision operating profit (PPOP) saw a significant decline of 41.6%, falling to ₹1,059 crore due to pressure on non-interest income. The bank's net interest margin (NIM) slightly moderated to 5.93% from 5.95% a year ago. Asset quality showed improvement, with gross non-performing assets (GNPA) decreasing to 1.61% from 1.69%, and net non-performing assets (NNPA) declining to 0.48% from 0.53%. The bank also benefited from a tax refund of ₹130 crore, compared to a tax expense of ₹57 crore in the previous year.
