Southwest Bancorp Reports First Quarter 2009 Results; Portfolio Loans Grow $32 Million

     April 16, 2009, Stillwater, Oklahoma . . . . Southwest Bancorp, Inc. (NASDAQ Global Select Market—OKSB), (“Southwest”), today reported net income available to common shareholders of $296,000, or $0.02 per diluted share for the first quarter 2009, compared to $5.2 million, or $0.36 per diluted share for the first quarter of 2008, and $3.0 million, or $0.20 per diluted share for the fourth quarter of 2008. At March 31, 2009, total assets were $2.9 billion.

     “We know that 2009 will be a challenging year, but we continue to focus on our strategic goal of building long-term shareholder value as we work through these difficult times,” stated Rick Green, President and Chief Executive Officer.

     “During the first quarter, we continued to follow our strategic vision of prudent loan growth in carefully selected markets in Texas, Oklahoma and Kansas; careful expansion of our community banking operations; and continued our focus on building liquidity. In the quarter, we increased portfolio loans by $31.8 million, up 1%, from year-end 2008 and increased our core deposits by $105.3 million, up 8%.

     “In early 2008, we decided to increase capital resources to support our operations during the uncertain economic conditions ahead. By March 31, 2009, we had increased our shareholders’ equity to $300.4 million, up $76.3 million, or 34%, over March 31, 2008, and our capital ratios substantially exceeded the levels for regulatory classification as “well-capitalized”.

     “The decrease in first quarter net income available to common shareholders is the result of an increase in the provision for loan losses, a decrease in net interest income, and dividends on the preferred stock we issued late last year. The changes in net interest income and the provision for loan losses were driven mainly by economic conditions that adversely affect our net interest margin and the value of commercial real estate securing loans. These negative factors were partially offset by decreases in income taxes and personnel expenses and an increase in gains on sale of investment securities.”

     Please review the following “Financial Overview” and the accompanying tables for important additional information regarding our results and plans.

Financial Overview

     Condition: Total assets were $2.9 billion at March 31, 2009, an increase of 2% from December 31, 2008. At March 31, 2009 total loans were $2.6 billion, also an increase of 2% from December 31, 2008.

     At March 31, 2009, the allowance for loan losses was $46.3 million, up 54% from March 31, 2008 and up 16% from year-end 2008, and represented 1.83% of portfolio loans versus 1.31% at March 31, 2008 and 1.59% at December 31, 2008. The methodology used to determine the appropriate amount of the allowance for loan losses at a particular time includes consideration of risk factors related to Southwest and to our markets, including regular assessments of national and local economic conditions and trends. The provision for loan losses increased by $8.6 million, or 387%, over the provision for the first quarter of 2008.

Southwest Bancorp Reports First Quarter 2009 Results; Portfolio Loans Grow $32 Million

     Nonperforming assets to portfolio loans and other real estate owned were 3.53% at March 31, 2009 compared to 1.41% at March 31, 2008 and 2.80% at December 31, 2008. A breakdown of portfolio loans and nonperforming assets by type are shown in the following table:

Total	$	2,526,293		100.00	%	$	89,286		100.00	%

     Nonaccrual loans, which are the majority of nonperforming assets, were $73.4 million as of March 31, 2009, an increase of $14.1 million from December 31, 2008. These loans are carried at their estimated collectible amounts and no longer accrue interest. The increase in nonaccrual loans is primarily due to three collateral dependent lending relationships that are secured by real estate. Loans 90 days or more past due, another component of nonperforming assets, increased $5.9 million from December 31, 2008. These loans are deemed to have sufficient collateral and are in the process of being collected. Performing loans considered potential problem loans, which are not included in the past due, nonaccrual, or restructured categories, but for which known information about possible credit problems cause management to be uncertain as to the ability of the borrowers to comply with the present loan repayment terms, amounted to approximately $133.8 million at March 31, 2009, an increase of $2.3 million from December 31, 2008. These loans are subject to continuing management attention and are considered by management in determining the level of the allowance for loan losses.

     Total deposits were $2.3 billion at March 31, 2009, up $150.0 million from December 31, 2008. Core deposits were 64% of total deposits or $1.5 billion, an increase of $105.3 million, or 8%, from December 31, 2008. At March 31, 2009, wholesale funding accounted for 21% of total funding compared to 24% at December 31, 2008.

     On March 31, 2009, Southwest exceeded all applicable regulatory capital requirements, having a total risk-based capital ratio of 14.11%, a Tier 1 risk-based capital ratio of 12.85%, and a leverage ratio of 12.72%. Southwest and each of its banking subsidiaries met the criteria for regulatory classification as “well-capitalized”. Southwest’s capital exceeded the minimum to be classified as “well-capitalized” by $118.1 million. Designation as a well-capitalized institution under regulations does not constitute a recommendation or endorsement by Federal bank regulators.

     First Quarter Results:

     Summary: The decrease in our net income available to common shareholders from the first quarter of 2008 was the result of an $8.6 million increase in the provision for loan losses, a $795,000 decrease in net interest income, a $538,000 increase in FDIC insurance and other insurance expense, and $875,000 in quarterly dividends on the preferred stock that we issued in December 2008, offset in part by a $2.5 million decrease in income tax expense, a $2.0 million decrease in personnel costs, and a $1.7 million increase in gain on sale of investment securities.

     Net Interest Income: Net interest income totaled $21.0 million for the first quarter of 2009 compared to $21.8 million for the first quarter of 2008 and $22.4 million for the fourth quarter of 2008. Net interest margin was 3.00% for the first quarter of 2009 compared to 3.45% for the first quarter of 2008, and 3.22% for the fourth quarter of 2008. The yield on earning assets decreased more rapidly than the rates paid on interest bearing liabilities.

     Provision for Loan Losses: The provision for loan losses totaled $10.9 million for the first quarter of 2009 compared to $2.2 for the first quarter of 2008 and $6.7 million for the fourth quarter of 2008. Net charge offs totaled $4.4 million, or 0.71% (annualized) of average portfolio loans for the first quarter of 2009, compared to $1.9 million, or 0.34% (annualized) and to $2.7 million, or 0.44% (annualized) of average portfolio loans, for the first and fourth quarters of 2008, respectively.

     Noninterest Income: Noninterest income totaled $6.5 million for the first quarter of 2009 compared to $4.7 million for the first quarter of 2008. The increase in noninterest income from the first quarter of 2008 was the result of a $1.7 million increase in gain on sale of investment securities and a $143,000 increase in service charges and fee income, offset in part by a $122,000 decrease in gain on sale of loans.

     Noninterest Expense: Noninterest expense decreased $1.2 million from the first quarter 2008 to the first quarter of 2009 to $14.6 million. The decrease consists of a $2.0 million decrease in personnel expense and an $112,000 decrease in other real estate expense, offset by a $538,000 increase in FDIC and other insurance expense, a $273,000 increase in occupancy expense, and a $108,000 increase in other general and administrative expenses.

     The efficiency ratio for the first quarter of 2009 improved to 53.06% from 59.69% and 53.37% for the first and fourth quarters of 2008, respectively.
