Bandhan Bank shares tumbled 15% on Wednesday to trade at ₹177.5 apiece despite the lender reporting a stronger-than-expected profit. It posted a 35% year-on-year rise in net profit to ₹502 crore for Q1 FY27. The stock fell after the bank lowered its FY27 profitability guidance and warned its net interest margin would remain under pressure over the next two quarters.
