### Footnotes:

(1) These stock appreciation rights (these "SARs") became vested and payable as of July 14, 2025. In accordance with the rules for filing a Form 4, the settlement of cash-settled SARs is treated as the simultaneous purchase of the number of shares of common stock the SARs represent and the sale of the same number of shares of common stock. Upon vesting, the SARs were only payable in cash and the reporting person did not receive any shares of the common stock, par value $1.00 per share (the "Common Stock"), of International Bancshares Corporation (the "Company").

(2) Represents the closing price of the Company's Common Stock on September 5, 2025, the date the SARs were exercised (the "Exercise Date").

(3) These SARs represent the right to receive, upon exercise, a cash amount equal to the number of shares of the Company's Common Stock underlying the SARs being exercised multiplied by the excess of the fair market value of one share of Common Stock on (i) the Exercise Date, and (ii) July 14, 2022, the date the SARs were granted (the "Grant Date").

(4) These SARs are subject to a seven-year vesting schedule and become exercisable in six percentage installments, vesting 5% on the second anniversary of the Grant Date, and 10%, 15%, 20%, 25%, and 25% on each respective anniversary of the Grant Date thereafter.
