Exhibit 99.1 BANCFIRST CORPORATION REPORTS FIRST QUARTER EARNINGS OKLAHOMA CITY, April 27 /PRNewswire-FirstCall/ -- BancFirst Corporation (Nasdaq: BANF) reported net income of $10.9 million or $0.68 diluted earnings per share for the first quarter of 2006. These results were unchanged from results reported for the first quarter a year ago. However, last year's results included $325,000 (after tax) of additional federal tax credits. Net interest income was $34.6 million, an increase of $2.9 million, or 9.1% over the first quarter of 2005. The Company's net interest margin improved to 4.77%, up from 4.67% a year ago. The increase is a result of the loan growth of $159 million from first quarter in 2005, combined with rising interest rates. The loan loss provision was $681,000 down $111,000 from the same period a year ago. Nonperforming loans and net charge-offs remain at historically low levels. Noninterest income totaled $13.4 million, an increase of $1.1 million or 8.6%. Noninterest expenses were $30.3 million, an increase of $3.3 million. The increase in noninterest expense is due primarily to expansion, marketing and the acquisition of Park State Bank, Nicoma Park. For the first quarter of 2006, the Company's tax expense was $6.2 million up from $5.4 million a year ago due largely to federal tax credits on certain loan transactions in 2005. The effective tax rate rose to 36.1% from 33.1% last year. The Company reported it was again recognized by Mergent's Dividend Achievers for 2006 as a company that has successfully delivered dividend increases to shareholders for 10 or more consecutive years. Just 3% of U.S. publicly listed companies met the criteria to be recognized as a Dividend Achiever. Last year marks the thirteenth consecutive year that BancFirst has had dividend increases of 10% or more. At March 31, 2006 the Company had total assets of $3.4 billion. Loans totaled $2.3 billion and deposits were $2.9 billion. The Company's stockholders equity was $311 million, or 9.25% of total assets.
