Announces Third Quarter Earnings</font></b></h1>

<p style="margin-left:0pt;margin-right:0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">LAREDO, Texas&#151;(BUSINESS WIRE)&#151;November 6, 2006&#150;International
Bancshares Corporation (&#147;IBC&#148;) (Nasdaq:IBOC - News) today reported net income
for the third quarter of 2006 of <b>$26.6</b>
million or <b>$.42</b> per share - basic
(<b>$.42 </b>per share - diluted)
compared to <b>$35.5</b> million or <b>$.56</b> per share - basic (<b>$.55 </b>per share - diluted) for the third
quarter 2005, which represents a decrease of <b><font style="font-weight:bold;">25</font>.1%</b> in net income and <b>23.6%</b> in diluted earnings per share.&#160;&#160; Net income for the first nine months of 2006
was <b>$85.2</b> million, or <b>$1.35</b> per share &#150; basic (<b>$1.33</b> per share diluted) compared to <b>$106.5</b> million, or <b>$1.67</b> per share &#150; basic (<b>$1.65</b> per share diluted) for the first nine
months of 2005, which represents a decrease of <b>20.0%</b>
in net income and <b>19.4%</b> in
diluted earnings per share.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In the third
quarter 2006, the Company incurred a securities loss of $880,000, after tax, to
reposition a portion of its securities portfolio.&#160; Additionally,
a loss of $836,000, after tax, was recorded to reflect the Company&#146;s share of
losses on an equity investment held by its lead bank.&#160; Net income for the third quarter of 2006 and
2005 was positively affected by gains on sales of loans of $763,000 and $1.9
million, after tax, respectively.&#160;
Additionally, net income has been negatively impacted by the inverted
yield curve and increasing competition for deposits.&#160; The Company has also been negatively impacted
by the increasing de novo branching activity by the Company in its markets
resulting in 20 new branches in 2006, 32 new branches in 2005, and 17 new branches
in 2004.&#160; The Company believes that the
de novo branching will help in attracting new low cost deposits and loans and
also help with the retention of current customers as more out of market banks
expand their branching activities in Texas; however, the Company realizes that
there is a certain amount of time before each branch becomes profitable and
thus negatively impacts earnings in the short term.&#160; The Company has continued to foster the
growth of loans to improve net interest income; however, this process of
expanding quality loan balances takes a certain amount of time and also
increases the provision for loan losses in periods of expansion.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Net income for the first nine months of 2006 was negatively impacted by a
$8.9 million, net of tax, charge to operations as a result of the loss of a IRS
tax lawsuit that was litigated during the third quarter of 2005 in the Federal
District Court in San Antonio, Texas and that relates to certain leasing
transactions previously discussed in Footnote 17 of the Notes to Consolidated
Financial Statements set forth in the Company&#146;s 2005 Annual Report.&#160; Because of the trial court judgment issued on
March 31, 2006, the uncertainty of the outcome at the appellate level and the
similarity between the litigated lawsuit and the other tax case that is
pending, the Company took the $8.9 million charge, net of tax. Net income for
the first nine months of 2005 was positively impacted by a $5.6 million
distribution, net of tax, from the January 2005 merger of the PULSE EFT Association
with Discover Financial Services, a business unit of Morgan Stanley, received
in the first and second quarter 2005.&#160;
The Company, as a member of the PULSE EFT Association received the cash
distributions based in part upon its volume of transactions through the PULSE
network.</font></p>

<p style="margin-left:0pt;margin-right:0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&#147;I&#146;m pleased with the Company&#146;s third quarter
earnings, as well as the results of the first nine months, despite the charge
related to the tax lawsuits, the very difficult environment associated with an
inverted yield curve, and the increasing competition for deposits and
loans.&#160; The Company has continued to grow
its operations and enhance long term shareholder value through aggressive de
novo branch expansion resulting in a decrease in the Company&#146;s earnings
compared to prior years; however, the Company believes it is necessary to
expand its footprint to better serve its current and future customers, as well
as, expand its market share,&#148; said Dennis E. Nixon, President and CEO.</font></p>

<p style="margin-left:0pt;margin-right:0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Total assets at September 30, 2006 were <b>$10.7</b> billion compared to <b>$10.4</b> billion at December 31, 2005. Total
net loans were <b>$4.8</b> billion at
September 30, 2006 and <b>$4.5 </b>billion at
December 31, 2005. Total deposits were <b>$6.7</b> billion at
September 30, 2006 and December 31, 2005.</font></p>
