IBC’s Strong Earnings Continue in the First Quarter of 2024

International Bancshares Corporation (NASDAQ:IBOC), one of the largest independent bank holding companies in Texas, today reported net income for the three months ended March 31, 2024 of $97.3 million or $1.56 diluted earnings per common share ($1.57 per share basic) compared to $101.6 million or $1.63 diluted earnings per common share ($1.64 per share basic), which represents a decrease of 4.3% in diluted earnings per share and a 4.2% decrease in net income over the corresponding period in 2023.

Net income for the first quarter of 2024 continues to be positively impacted by an increase in interest income earned on our investment and loan portfolios. The increase in interest is being driven by both an increase in the size of our investment and loan portfolios as well as rate changes as a result of the Federal Reserve Board actions to raise interest rates in 2022 and 2023. Net interest income has been impacted by an increase in interest expense, primarily driven by increases in rates paid on deposits throughout the latter part of 2023. We continue to closely monitor and adjust rates paid on deposits to remain competitive in the current economic environment and retain deposits. Net income for the period was negatively impacted by an increase in our provision for credit losses, which was primarily impacted by a charge-down of an impaired credit after the results of a bankruptcy related foreclosure.

“We are pleased with our continued success in 2024. We are also extremely pleased to have been ranked first in the S&P Global Market Intelligence best-performing Public Banks for 2023 listing and third in the Forbes America’s Best Banks listing. Our team is highly focused on ‘Doing More’ to deliver exceptional service and innovative products to our customers, as well as continuing our long-standing practices of balance sheet, asset liability and liquidity management. Those initiatives, coupled with strong cost controls and continued identification of opportunities for efficiencies across our system will continue to deliver positive financial results and ideally keep us at the top of the rankings in 2024,” said Dennis E. Nixon, president and CEO.

Total assets at March 31, 2024 were $15.4 billion compared to $15.1 billion at Dec. 31, 2023. Total net loans were $8.0 billion at March 31, 2024 compared to $7.9 billion at Dec. 31, 2023. Deposits were $12.0 billion at March 31, 2024 compared to $11.8 billion at Dec. 31, 2023.
