Stock Options | Note 5 — Stock Options ​ On April 5, 2012, our Board of Directors (the “Board”) adopted the 2012 International Bancshares Corporation Stock Option Plan (the “2012 Plan”). There were 800,000 shares of common stock available for stock option grants under the 2012 Plan, which were qualified incentive stock options (“ISOs”) or non-qualified stock options. Options granted may be exercisable for a period of up to 10 years from the date of grant, excluding ISOs granted to 10% shareholders, which may be exercisable for a period of up to only five years. On April 4, 2022, the 2012 Plan expired and was not renewed. ​ A summary of option activity under the 2012 Plan for the six months ended June 30, 2024 is as follows: ​
