(NASDAQ:ABNK), today reported first quarter results that reflect the successful continuation of its strategy to build its core businesses. For the quarter ended March 31, 2005, net income was $16.9 million, or $0.24 per diluted common share, compared to $15.3 million for the quarter ended March 31, 2004, or $0.22 per diluted common share. Adjusted for merger-related and name change expenses, and gains on sales of certain assets, net income would have been $18.9 million, or $0.26 per diluted common share, an increase of 10% from the same period last year. (Exhibit IV presents reconcilements of all non-GAAP disclosures.) Return on average assets and return on average common shareholders' equity for the three months ended March 31, 2005 were 0.91% and 11.66%, respectively, compared to 1.02% and 12.04%, respectively, for the same period in 2004. Adjusted for merger-related and name change expenses, and gains on sales of certain assets, return on average assets and return on average common shareholders' equity would have been 0.94% and 12.03% respectively. Total revenue for the first quarter of 2005 was $91.0 million, an increase of 22% over the same period in 2004 and up 1.6% linked quarter. Average loans held for investment were $4.58 billion, a 27% increase over the first quarter of 2004 and an increase of 3.8% linked quarter or 15% on an annualized basis. Average deposits were $5.46 billion, an increase of 22% over the comparable period in 2004 and 0.1% linked quarter. An account with average deposit balances of $155 million in the fourth quarter of 2004 exited the bank in the first quarter of 2005 due to a change in the client's business relationships. This account represented the highest priced deposit relationship in the bank and these funds were replaced at a lower cost. Excluding this account, average deposits grew $86.2 million linked quarter, up 1.6%. Average assets increased to $7.56 billion, a 26% increase from the first quarter of 2004 and an increase of 3.2% linked quarter. "As I reflect back over the past two years, I am very pleased with our progress," said Paul Murphy, Chief Executive Officer. "First of all, our core growth has been exceptional. Additionally, we accomplished three strategic mergers with great banks and increased our branch network from 33 to more than 75 branches in Texas' two largest cities where we believe strong opportunities exist for our type of banking. While important to our strategic growth, these activities have had a cost in short term merger-related expenses, core deposit intangible amortization expense, and in higher interest expense. However, the results this quarter from our focus on merger integration, expense management and deposit growth are meeting our expectations. We believe we are very well-positioned for the future." Net Interest Income Net interest income increased to $62.2 million, or 18%, for the first quarter of 2005 over the same period a year earlier and decreased 0.9% linked quarter. The taxable-equivalent net interest margin decreased 4 basis points linked quarter to 3.87%. The yield on the loan portfolio increased by 31 basis points and the yield from the securities portfolio increased 9 basis points from the fourth quarter of 2004. Cost of funds, including demand deposits, was 147 basis points for the quarter, up 28 basis points linked quarter. "Our lending capabilities are fully engaged and we see deposit growth as key. We are very pleased that, in addition to treasury management, Debbie Innes will head up our retail group as we continue the growth in this area since its successful launch six years ago. Her track record has been outstanding and the team she has built is extraordinary. We are looking forward to having her enthusiasm and dedication in this expanded role," said Scott McLean, President. "Loan growth was fairly well distributed among the lending groups with the primary growth in the real estate and the commercial and industrial groups. We also are delighted with our team in the Dallas-Fort Worth Metroplex, which has grown loans outstanding to over $400 million at quarter end. The lending and treasury management teams are making some excellent headway in that market." The fixed rate portion of the loan portfolio continues to decline both in percentage and in dollar terms. Since June 2004, when it was 33% of the portfolio, the fixed rate portion of the loan portfolio has declined to 30% at March 31, 2005. The shared national credit portion of the portfolio declined to $755 million during the quarter from $766 million at year-end 2004. "The banking industry continues to face a challenging environment due to a flattening yield curve and margin compression and we are no exception," added Murphy. "Fortunately, our strong sales culture is enabling us to grow the Bank despite these headwinds." Noninterest Income For the three months ended March 31, 2005, noninterest income totaled $28.8 million, a 31% increase from the same period in 2004 and a 7.4% increase linked quarter. Service charges on deposit accounts were $11.3 million, down 12% linked quarter, primarily due to seasonal factors on balance levels on some major depository accounts, to an increase in the earnings credit rate, and to lower retail service charges. Investment services and trust fee income was consistent with a record fourth quarter of 2004 and was up 21% over prior year. Other fee income increased 5.7% linked quarter to $7.34 million driven by gains in retail services, loan commitment and servicing fees. Other operating income increased due to an $863,000 gain on the sale of the Bank's interest in the PULSE network and a gain on the sale of an unused drive-through facility in downtown Houston of $1.2 million. Noninterest Expenses Noninterest expenses before merger-related and name change expenses and intangible amortization expense declined $543,000 linked quarter. Adjusting for merger-related and name change expenses and intangible amortization expense, first quarter expenses would have been $59.1 million, down from fourth quarter adjusted expenses of $59.6 million. Core deposit intangible amortization expenses were $2.2 million in the first quarter, unchanged linked quarter. On an as reported basis, noninterest expenses were $64.2 million for the quarter compared to $64.0 million linked quarter and $50.1 million in the first quarter of 2004. "We are moving toward a more normal operating expense level," said Randy Meyer, Chief Financial Officer. "As predicted, operating expenses in occupancy and the other expense categories continue to decline as we experience the cost saves anticipated with the Klein Bank operational merger which was completed on March 7. We anticipate the $2.2 million core deposit intangible amortization expenses in this quarter will begin to decline by the fourth quarter of this year. Our goal is continued improvement as we complete the merger integration process and right-size our expense run rate to revenue growth rates." On a taxable-equivalent basis, the efficiency ratio was 66.94% for the first quarter of 2005 down from 67.83% linked quarter. Adjusted for merger-related and name change expenses, and gains on sales of certain assets, the taxable-equivalent efficiency ratio would have been 65.28% compared to 65.46% on a linked quarter basis. The effective tax rate for the first quarter 2005 was 28.5% compared to 24.5% linked quarter. Asset Quality Asset quality continued to be a strength during the first quarter. Nonperforming assets declined to $22.1 million, or 0.48% of loans and other real estate, compared to $25.1 million, or 0.55% of loans and other real estate, linked quarter. Allowance for credit losses to total loans is 1.09% at March 31, 2005, compared to 1.11% linked quarter. The allowance for loan losses to nonperforming loans was 358.92% at March 31, 2005 compared to 304.50% linked quarter. Total Loans, Deposits, Investments, Assets, and Equity Total loans held for investment were $4.61 billion at March 31, 2005, an increase of 24% from the first quarter of 2004 and 1.5% on a linked quarter basis. Total deposits at March 31, 2005 were $5.81 billion, an increase of 23% from the first quarter of 2004 and 3.3% on a linked quarter basis. Investment securities were $1.92 billion at March 31, 2005, an increase of 22% from the first quarter of 2004 and a decrease of 3.3% linked quarter. At March 31, 2005, total assets were $7.56 billion, an increase of 24% from the first quarter of 2004 and an increase of 0.7% linked quarter. Total shareholders' equity was $577.2 million at March 31, 2005 and the Tier 1 leverage ratio was 7.80%. Southwest Bancorporation of Texas, Inc., the parent company of Amegy Bank N.A., is the largest independent bank holding company headquartered in Houston, Texas. The Company focuses on commercial lending, treasury management and investment services for businesses in the southwest, private financial management and trust services for families and individuals, and retail and mortgage banking services.

Utilization of Financial and Certain Non-GAAP Financial Measures: Consolidated financial information and supplemental unaudited data schedules follow in this release. Exhibits I and II provide additional information on the net interest margin, including average balances and average rates for both assets and liabilities for the periods presented. Exhibit III presents quarterly comparative data. Exhibit IV presents reconcilements of non-GAAP disclosures. Management believes that these non-GAAP financial measures provide information useful to investors in understanding the underlying operational performance of the Company and facilitates comparisons with the performance of others in the financial services industry. Because of the significant amount of deposit base intangible amortization, Management believes the exclusion of this expense provides investors with consistent and meaningful comparisons to other financial services firms. Management also believes the presentation of net interest income on a tax-equivalent basis ensures comparability of net interest income arising from both taxable and tax-exempt sources and is consistent with industry standards. Management uses non-GAAP measures internally for performance measurement and goal setting for incentive compensation purposes and for benchmarking purposes in relation to peer institutions in the banking industry. Although Management believes the above non-GAAP financial measures enhance investors' understanding of its business and performance, these non-GAAP financial measures should not be considered as an alternative to GAAP basis financial measures.
