SUMMIT BANCSHARES REPORTS
FIRST QUARTER 2005 EARNINGS

Fort Worth, Texas – Summit Bancshares, Inc. (NASDAQ:SBIT), the bank holding company for Summit Bank, N.A., today reported net income for the first quarter of 2005 of $3,013,000, or $0.24 per diluted common share, compared to $2,451,000, or $.19 per diluted common share, for the comparable 2004 period, a 26.3% increase in per share earnings.  Return on average assets and return on average shareholders’ equity were 1.23% and 16.16%, respectively, for the quarter ended March 31, 2005 compared to 1.22% and 14.06%, respectively, for the same quarter in 2004.  The per share earnings and all historical per share data have been restated to reflect a two-for-one stock split that was effective December 31, 2004.  Also Summit completed its acquisition of ANB Financial Corporation and its subsidiary, Arlington National Bank (“ANB”), effective May 1, 2004.  The results of operations for ANB have been included in Summit’s consolidated financial statements since the purchase date. 

Philip E. Norwood, Chairman, President and Chief Executive Officer stated “We are pleased to report positive financial performance of the Company for the first quarter of 2005.  Compared to the first quarter of the prior year average loans and average deposits increased 23.2% and 23.9% respectively.  Net interest income increased 23.5% reflecting an increase of eleven basis points in net interest margin and a 21.5% increase in average earning assets compared to the first quarter of 2004.  The increase in net interest margin reflects the increase in market interest rates.”

He further stated, “As recently announced we are excited to have Kim Dignum and her staff of Dignum Financial Services join the Company as a department of the Bank.  Kim brings many years of providing personal financial planning and other investment services to her customers.  Currently DFS has $85 million of assets under management.  Her talents will add an important service to the Bank’s customers.”

Mr. Norwood also noted, “The Company celebrated its 30 year anniversary in January of 2005.  In that 30 year period the Company has grown to approximately one billion dollars in assets with shareholders’ equity of $74.4 million and a market capitalization of approximately $210 million.  These are significant milestones for the Company.”

Net interest income of $10.2 million for the first quarter of 2005 improved $2.0 million, or 23.5% over the first quarter of 2004.  Since the Company is somewhat more sensitive to market interest rate changes than other community banks due to its heavier commercial lending focus, the net interest margin increased to 4.47% for the first quarter of 2005 compared to 4.36% for the first quarter of the prior year partially reflecting the recent increases to the market interest rate environment.

A provision for loan losses was $225,000 for the first quarter of 2005 while the provision for loan losses was $605,000 for the same quarter of 2004.  For the first quarter of 2005 the Company experienced net loan loss recoveries of previously charged off loans of $107,000, which represented net recoveries to average loans for the quarter of 0.02%.  As of March 31, 2005, the allowance for loan losses as a percentage of total loans was 1.47% and also represented over three times the balance of nonperforming loans as of the end of the first quarter of 2005.  As of March 31, 2005, nonperforming loans were $3.3 million, or 0.46% of total outstanding loans.

Non interest income for the first quarter of 2005 was $1,880,000, a $313,000 increase over the first quarter of 2004.  The increase reflected improvements in service charges on deposit accounts of $76,000, an increase in other fees of $271,000 and a decrease in extraordinary income related to the sale of assets with the first quarter of last year having a $168,000 gain while the first quarter of this year had a gain of $134,000.  These increases in non interest income also reflect the impact of the ANB acquisition.

Non interest expenses of $7,252,000 for the first quarter of 2005 increased $1,722,000 compared to the first quarter of last year.  Primarily the increase is due to the inclusion of ANB in the 2005 first quarter results as well as expenses in 2005 related to compliance with the Sarbanes Oxley Act’s Section 404 which required additional expenditures for auditing and consulting fees in the amount of approximately $125,000.
