IBC Reports Strong Earnings for the First Six Months of 2026

International Bancshares Corporation (NASDAQ:IBOC), one of the largest independent bank holding companies in Texas, today reported net income for the six months ended June 30, 2026 of $198.0 million or $3.18 diluted earnings per common share ($3.18 per share basic), compared to $197.0 million or $3.16 diluted earnings per common share ($3.17 per share basic), which represents an increase of 0.5% in net income and 0.6% in diluted earnings per share over the corresponding period of 2025. Net income for the three months ended June 30, 2026 was $95.8 million or $1.54 diluted earnings per common share ($1.54 per share basic) compared to $100.1 million or $1.61 diluted earnings per common share ($1.61 per share basic), which represents a decrease of 4.3% in net income and 4.3% in diluted earnings per share over the corresponding period of 2025.

Net income for the first six months of 2026 continued to be positively affected by interest earned on our investment and loan portfolios driven primarily by both an increase in the size of those portfolios and the current rate environment. Net interest income was also positively affected by a decrease in interest expense, primarily driven by a redistribution in rates paid on deposits. We continue to closely monitor rates paid on deposits to remain competitive to grow and retain deposits. The strong net income reported for 2026 compared to the same period of 2025 was negatively impacted by an increase in our provision for credit loss expense, driven primarily by an increase in the size of our loan portfolio, a change in the level of non-accrual loan balances and the reevaluation of the specific provisions for credit losses related to those loans. Although the provision for credit losses has increased, no actual losses on those loans have been, or may ever be, realized.
