IDBI Bank’s reported standalone net profit fell to ₹2,205.45 crore in the September quarter, down about 39.2% from ₹3,627.36 crore a year earlier. The comparison includes an important base effect: the bank says last year’s quarter contained a ₹1,699 crore one-off gain from selling its strategic investment in NSDL.
The 17 October release for the quarter ended 30 September 2026 separately says net profit grew 14% year on year when that prior-period gain is excluded. That is the bank’s excluding-one-off comparison, not growth in reported net profit. The two statements answer different questions and should not be merged into one headline claim.

How the reported decline is calculated
From the signed filing: (₹2,205.45 crore − ₹3,627.36 crore) ÷ ₹3,627.36 crore × 100 = approximately −39.2%. The release rounds current profit to ₹2,205 crore and prior profit to ₹3,627 crore. A rounded press-release figure and a more precise filing figure are not conflicting results.
What the bank’s alternative comparison does—and does not—say
The issuer removes the previous year’s identified NSDL gain for its 14% comparison. CapKet attributes this calculation to the issuer; it is not an independently audited normalised-profit measure or a replacement for the reported accounts. A one-time investment-sale gain is different from recurring interest earnings, so readers should retain both views rather than choose only the more favourable percentage.
Interest earnings improved, but risks remain
NII is interest earned less interest paid, not total income or profit. The bank reports higher NII and NIM while its gross and net non-performing loan ratios were 2.12% and 0.17%. These ratios are snapshots, not a guarantee against future credit losses. The report does not establish an analyst-consensus verdict, a completed ownership change or an expected share-price return.
