DETAILED FINANCIALS
Texas Capital Bancshares, Inc. reported net income of $7.7 million for the fourth quarter of 2005 compared to $6.0 million for the fourth quarter of 2004. Net income for the year ended 2005 was $27.2 million compared to $19.6 million for the year ended 2004. On a fully diluted basis, earnings per share were $.29 and $1.02, for the three- and twelve-month periods ended December 31, 2005, respectively. For 2004 the EPS comparisons for the three- and twelve-month periods were $.23 and $.75, respectively.

Return on average equity was 14.53 percent and return on average assets was 1.04 percent for the fourth quarter of 2005 compared to 12.50 percent and .94 percent, respectively, for the fourth quarter of 2004. Return on average equity was 13.29 percent and return on average assets was .97 percent for 2005 compared to 10.74 percent and .82 percent, respectively, for 2004. The increase in net income and improvement in return on assets and return on equity in 2005 as compared to 2004 results are attributed to growth in net interest income which came from continued earning asset growth, as well as an improvement in net interest margin.

Net interest income was $28.5 million for the fourth quarter of 2005, compared to $21.5 million for the fourth quarter of 2004. The increase was due to an increase in average earning assets of $346.5 million over levels reported in the fourth quarter of 2004 and a 55 basis point improvement in the net interest margin. The increase in average earning assets included a $489.5 million increase in average loans held for investment, an increase of $5.4 million in loans held for sale, offset by a decrease of $163.9 million in average securities. The net interest margin in the fourth quarter of 2005 was 4.13 percent, a 55 basis point increase from the fourth quarter of 2004 and a 16 basis point increase from the third quarter of 2005. The improvement in the net interest margin for the fourth quarter of 2005 as compared to the fourth quarter of 2004 resulted primarily from a 171 basis point increase in the yield on earning assets offset by a 146 basis point increase in the cost of interest-bearing liabilities.

Average interest bearing liabilities increased $246.4 million from the fourth quarter of 2004, which included a $532.5 million increase in interest bearing deposits, offset by a $310.2 million decrease in other borrowings. For the same periods, the average balance of demand deposits increased 36.6 percent to $458.7 million from $335.9 million.

Key measures of credit quality remained very favorable during the fourth quarter of 2005. For the year, the Company realized a $199,000 net recovery of loans previously charged off compared to net charge offs of $717,000 in 2004. Non-accrual loans were $5.7 million, or 0.27 percent of loans, at year-end 2005, compared to $5.9 million, or 0.37 percent of loans, at year-end 2004. Loans 90 days past due and still accruing were $2.8 million at year-end 2005 and included $2.5 million in premium finance loans, compared to $209,000 for 2004. The premium finance loans are secured by obligations of insurance carriers to refund premiums on cancelled insurance policies. The refund of premiums from the insurance carriers can take up to 180 days from the cancellation date. Due to the experience in loan recoveries and other factors considered in the methodology for assessing the adequacy of the allowance for possible loan losses, the Company did not record a provision for possible loan losses in any quarter of 2005. Reserve coverage of losses, non-performing assets and classified loans remains strong. In management’s opinion, the reserve is sufficient to cover all reasonably expected losses in the portfolio and is derived from consistent application of the methodology for establishing the adequacy of reserves for Texas Capital Bank’s loan portfolio.

Non-interest income for the fourth quarter of 2005 increased $2.3 million, or 62 percent, to $6.0 million from $3.7 million in the fourth quarter of 2004. The increase is primarily related to a $1.0 million increase in gains on sale of mortgage loans to $2.1 million from $1.1 million. Insurance commission income increased $532,000 due to increased focus on the insurance business.

Non-interest expense for the fourth quarter of 2005 increased $6.8 million or 43 percent, to $22.7 million from $15.9 million in the fourth quarter of 2004. The increase is primarily related

2

to a $4.1 million increase in salaries and employee benefits to $13.9 million from $9.8 million. The increase in salaries and employee benefits resulted from an increase in the total number of employees related to general business growth, additional staffing for the Houston office, addition of the premium finance business, the continued expansion of the residential mortgage lending division, increased focus on the insurance business and increased incentive compensation reflective of the Company’s performance.

(1)	The loan averages include loans on which the accrual of interest has been discontinued and are stated net of unearned income.
(2)	Taxable equivalent rates used where applicable.
(3)	Revenue includes origination fees and other loan fees for our residential mortgage loans that are earned when the loan is sold. This increases our overall yield on these loans since most of the mortgage loans are on our books for less than 30 days.
