IBOC International Bancshares Corporation

International Bancshares Corporation ("IBC") (NASDAQ:IBOC) today reported net income for the second quarter of 2006 of $34.7 million or $.55 per share - basic ($.54 per share - diluted) compared to $33.4 million or $.52 per share - basic ($.52 per share - diluted) for the second quarter 2005, which represents an increase of 3.9 percent in net income and 3.8 percent in diluted earnings per share. Net income for the first six months of 2006 was $58.6 million, or $.93 per share - basic ($.92 per share diluted) compared to $71.0 million, or $1.12 per share - basic ($1.10 per share diluted) for the first six months of 2005, which represents a decrease of 17.5 percent in net income and 16.4 percent in diluted earnings per share. Net income for the first six months of 2006 was negatively impacted by a $8.9 million, net of tax, charge to operations as a result of the loss of an 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's 2005 Annual Report. 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 six 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. 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. "I'm pleased with the Company's second quarter earnings, as well as the results of the first six months, despite the charge related to the tax lawsuits. The Company has continued to grow its operations and enhance long term shareholder value through aggressive de novo branch expansion," said Dennis E. Nixon, President and CEO.
