State Bank of India’s shares tumbled the most in three months after the nation’s top lender by assets reported weaker-than-expected net interest income.

Net interest income came in at 443.8 billion rupees ($4.7 billion) for the quarter ended March 31, missing analysts’ estimates of 467.45 billion rupees. The stock slumped as much as 7.4%, set for the biggest drop since Feb. 1.
