Exhibit 99.1 BancFirst Corporation Reports 2003 Earnings OKLAHOMA CITY, Jan. 22 /PRNewswire-FirstCall/ -- BancFirst Corporation (Nasdaq: BANF) today reported its earnings results for 2003 of $31.9 million or diluted earnings per share of $4.00. The 2003 results compare with $33.6 million or $4.06 diluted earnings per share in 2002. The continued compression of the net interest margin along with higher expenses in 2003 impacted this year's results. However, the Company's stock buyback program improved earnings per share on slightly lower net income. For the fourth quarter, net interest income increased $1.0 million to $28.4 million compared with the same period in 2002. The loan loss provision was $1.4 million versus $1.7 million for the same period a year ago. Noninterest income of $11.6 million was $200,000 below the amount reported in the fourth quarter of 2002. Noninterest expenses in 2003 increased to $26.4 million from $24.6 million in the fourth quarter for the prior year. The current environment of historically low interest rates has negatively affected the Company's net interest margin. In a low rate environment, the value of the Company's noninterest-bearing funds is reduced, causing a decrease in the Company's net interest margin. Total assets of the Company reached $2.92 billion at December 31, 2003 compared to $2.8 billion at year end 2002. Total loans increased $132.4 million to $1.95 billion from a year ago of which $70.0 million, net of acquisitions, came in the fourth quarter. Total deposits of $2.6 billion increased $157.0 million from the fourth quarter of 2002. Stockholders' equity increased to $255.4 million at December 31, 2003. During the fourth quarter, the Company completed its acquisitions of Lincoln National Bank with branches in Oklahoma City and Del City, and two branches from Gold Bank in Hobart and Lone Wolf. The Company's principal subsidiary bank, BancFirst, is Oklahoma's largest state-chartered bank with 86 banking locations serving 42 communities across Oklahoma.
