Exhibit 99.1 BancFirst Corporation Reports First Quarter Earnings OKLAHOMA CITY, April 20 /PRNewswire-FirstCall/ -- BancFirst Corporation (Nasdaq: BANF) today reported net income for the first quarter of 2004 of $8.2 million, compared to $8.6 million for the first quarter of 2003. Diluted earnings per share for the quarter were $1.03, compared to $1.07 per share for 2003. The decrease in net income was primarily due to continued margin compression from historically low interest rates coupled with higher operating costs. Net interest income for the first quarter of 2004 was $27.9 million, compared to $26.7 million in 2003. The net interest margin for the first quarter of 2004 was 4.20%, compared to 4.32% for the first quarter of 2003. Provision for loan losses in the first quarter of 2004 was $720,000 versus $783,000 in the same period of 2003. Noninterest expense increased $1.60 million to $26.2 million. The increase is mainly due to higher personnel costs partly related to the Gold Bank and Lincoln Bank acquisitions consummated in the fourth quarter of 2003. The Company's assets totaled $3.05 billion at March 31, 2004, up from $2.84 billion at March 31, 2003. Total loans increased $121 million to $1.94 billion, from $1.82 billion at the end of the first quarter of 2003. Nonperforming assets at the end of the first quarter totaled $20.2 million, compared to $20.8 million a year earlier. Deposits grew $195 million to $2.67 billion at March 31, 2004, from $2.48 billion at the same date in 2003. Stockholders' equity increased to $264 million, from $243 million a year earlier.
