International Bancshares Corporation has adopted Third Amended and Restated By-Laws that significantly change how shareholders can bring legal claims related to the company’s internal affairs. The changes expand shareholders’ ability to file derivative lawsuits and broaden where such cases may be heard.
The new By-Laws remove the prior requirement that a shareholder or group must beneficially own three percent of the company’s outstanding common stock to institute or maintain a derivative proceeding. They also eliminate an exclusive forum clause that had restricted internal claims to specified Texas and federal courts, and they end a provision requiring shareholders, directors, and officers to waive their right to a jury trial for internal entity claims and other claims against the company, to the fullest extent permitted by law. These amendments took effect on May 12, 2026.
