International Bancshares Corporation (NASDAQ: IBOC), one of the largest independent bank holding companies in Texas, today reported net income for the three months ended Sept. 30, 2025 of $108.4 million or $1.74 diluted earnings per common share ($1.74 per share basic) compared to approximately $99.8 million or $1.60 diluted earnings per common share ($1.60 per share basic), which represents an increase of 8.8% in diluted earnings per share and an increase of 8.6% in net income over the corresponding period in 2024. Net income for the nine months ended Sept. 30, 2025 was $305.4 million or $4.91 diluted earnings per common share ($4.91 per share basic) compared to $294.1 million or $4.72 diluted earnings per common share ($4.73 per share basic), which represents an increase of 3.8% in net income and 4.0% in diluted earnings per share over the corresponding period of 2024.

Net income for the first nine months of 2025 continues to be positively impacted by an increase in interest income earned on our investment and loan portfolios, as discussed in prior periods. Net interest income has also continued to be negatively impacted by an increase in interest expense, primarily driven by increases in rates paid on deposits. We continue to closely monitor and adjust rates paid on deposits to remain competitive to grow and retain deposits, especially in light of the recent action by the Federal Reserve Board to decrease interest rates. Net income for the first nine months of 2025 was also positively impacted by a decrease in our provision for credit loss expense.

“As we move to the last quarter of 2025, we are extremely pleased and proud to continue our industry-leading financial results. We will remain focused and vigilant on delivering superior customer service, and continued execution of our long-standing practices of balance sheet, asset, liability and liquidity management, and strong cost controls. We believe that with continued focus on these established practices supported by new AI initiatives to create efficiencies across our system, we will continue to deliver industry-leading financial results. We believe this focus will continue to keep us at the top of the rankings when compared to other publicly held banks in America,” said Dennis E. Nixon, president and CEO.
