Insights

Bank earnings analyst

Full-year growth was modestly positive, while Q4 showed some pressure.

International Bancshares delivered essentially flat but slightly higher 2025 earnings, with net income of $412.3 million and diluted EPS of $6.62, both up about 0.8% versus 2024. That suggests stable profitability over the year.

Quarterly trends were softer, as Q4 2025 net income of $106.9 million and diluted EPS of $1.71 fell roughly 7%–8% from Q4 2024. Higher interest income from larger portfolios and the rate environment was offset by higher deposit costs.

Balance-sheet growth was steady, with assets at $16.6 billion, net loans at $9.3 billion, and deposits at $12.4 billion as of December 31, 2025. Management’s comments emphasize ongoing cost control and new AI initiatives, but actual impact will be reflected in future annual and quarterly results.

IBC Reports Strong Earnings in 2025

LAREDO, Texas—(BUSINESS WIRE)— February 26, 2025—International Bancshares Corporation (NASDAQ:IBOC), one of the largest independent bank holding companies in Texas, today reported annual net income for 2025 of approximately $412.3 million or $6.62 diluted earnings per common share ($6.63 per share basic) compared to approximately $409.2 million or $6.57 diluted earnings per common share ($6.58 per share basic), which represents an increase of approximately 0.8 percent in diluted earnings per share and 0.8 percent increase in net income over the corresponding period in 2024. Net income for the three months ended December 31, 2025 was approximately $106.9 million or $1.71 diluted earnings per common share ($1.72 per share basic), compared to approximately $115.1 million or $1.85 diluted earnings per common share ($1.85 per share basic) for the same period in 2024, representing a decrease of approximately 7.1 percent in net income and a 7.6 percent decrease in diluted earnings per share.

​

Net income for 2025 continued to be positively impacted by an increase in interest income earned on our investment and loan portfolios driven primarily by both an increase in the size of our investment and loan portfolios and the current rate environment.  Net interest income has been 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.

​

“We are extremely pleased and proud to continue our industry-leading financial results in 2025, which has kept us at the top of the rankings compared to other publicly held bank holding companies in America.  As we move into 2026, we will remain focused and vigilant on delivering superior customer service, continued execution of our long-standing practices of balance sheet, asset, liability, and liquidity management, strong cost controls, and evaluating processes for efficiencies across our organization using new AI initiatives.  We believe that with continued focus on these established practices we will continue to deliver industry-leading financial results,” said Dennis E. Nixon, president and CEO.  

​

Total assets at December 31, 2025 were approximately $16.6 billion compared to approximately $15.7 billion at December 31, 2024.  Total net loans were approximately $9.3 billion at December 31, 2025 compared to approximately $8.7 billion at December 31, 2024.
