Bank equity & dividends analyst

IBC modestly raises its semi-annual dividend, signaling continued willingness to return cash to shareholders.

International Bancshares Corporation approved a semi-annual cash dividend of $0.73 per share, a 4.3% increase from the last dividend. For income-focused holders, this reflects a measured step-up in regular cash distributions rather than a large change in payout policy.

The record date is February 13, 2026, with payment on February 27, 2026, which sets clear timing for when shareholders must own the stock to receive the dividend. Actual impact on investors depends on position size and how this dividend level compares to their income expectations.
