EXHIBIT 99.1 SOUTHSIDE BANCSHARES, INC. ANNOUNCES THIRD QUARTER EARNINGS NASDAQ NATIONAL MARKET SYMBOL - "SBSI" Tyler, Texas (October 23, 2003) B. G. Hartley, Chairman and Chief Executive Officer of Southside Bancshares, Inc., reported financial results for the third quarter and nine months ended September 30, 2003. "For the nine months ended September 30, 2003 net income decreased $737,000 or 7.2% to $9,534,000 compared to $10,271,000 for the same period in 2002," stated B. G. Hartley. Net income decreased $1,394,000 or 33.6% to $2,750,000 for the third quarter ended September 30, 2003 compared to $4,144,000 for the same period in 2002. Earnings per diluted share were $0.91 and $0.98 for the nine months ended September 30, 2003 and 2002, respectively, a decrease of $0.07 or 7.1%. Earnings per diluted share were $0.26 and $0.39 for the third quarters ended September 30, 2003, and 2002. The annualized return on average shareholders' equity for the nine months ended September 30, 2003 was 14.96% compared to 18.65% for the same period in 2002. The annualized return on average assets was 0.95% for the nine months ended September 30, 2003 compared to 1.07% for the same period in 2002. On September 4, 2003 Southside Capital Trust I (the "Trust"), a subsidiary of Southside Bancshares, Inc. announced the redemption on October 6, 2003 of all of its 8.50% Cumulative Trust Preferred Securities and 8.50% Trust Common Securities which totaled $20,618,560. Concurrent with the Trust taking such action Southside Bancshares redeemed all of its $20,618,560 8.50% debentures due June 30, 2028 (the "Debentures") which were held exclusively by the Trust. In connection with the redemption of the Debentures, Southside Bancshares expensed $1,034,000 of unamortized origination cost associated with the Debentures during the third quarter. Southside Bancshares funded the redemption through the issuance of $20,000,000 of trust preferred securities and $619,000 of trust common securities that will adjust quarterly at a rate equal to the three month LIBOR plus 294 basis points. The initial rate for the trust preferred securities was 4.08%. This initial lower interest rate should provide interest savings beginning in the fourth quarter and should provide a better match for the overall interest rate sensitivity position of Southside Bancshares. In addition to the amortization expense of $1,034,000 discussed above, the decrease in net income for the quarter ended September 30, 2003, when compared to the same period in 2002, was primarily attributable to a 65.8% decrease in the gains on sales of securities available for sale or $1,345,000 and a 15.6% decrease in net interest income of $1,344,000. These items were partially offset by an increase in noninterest income, excluding, security gains of $1,290,000 or 32.8%, primarily as a result of increased deposit fee income and fee income from the sale of mortgage loans. Provision for loan losses decreased $530,000 due to total loans declining slightly and the anticipated level of problem assets at September 30, 2003 remaining consistent with the prior period. Net interest income decreased as a result of decreases in the Company's net interest margin and spread during the third quarter of 2003 when compared to the same period in 2002, which was due in large part to significantly lower mortgage interest rates and the lower overall interest rate environment during the second quarter ended June 30, 2003. This led to substantially increased residential mortgage refinancing nationwide and in the Company's market area combined with increased repricing of all of the Company's other loan types during the third quarter ended September 30, 2003. Increased prepayments associated with the Company's mortgage-backed securities, residential mortgage loans and the increase in repricing of other loan types could impact the Company's net interest margin in the future should long-term interest rates decrease to May and June 2003 levels. During the third quarter 2003 long-term interest rates increased from the lows experienced during May and June 2003. This caused a slowing in refinancings which should reduce mortgage prepayments for specific coupons during the fourth quarter. Other factors that should improve Southside's net interest margin and spread include new deposit repricing strategies fully implemented during the second quarter, $31.9 million of fixed rate Federal Home Loan Bank of Dallas ("FHLB") advances currently at an average rate of 3.86% that will reprice during the fourth quarter of 2003, and the reduction in interest expense on $20,000,000 of Southside Bancshares trust preferred securities beginning during the fourth quarter ended December 31, 2003 as explained above. In addition, during the first quarter of 2004 $17 million of fixed rate FHLB advances currently at an average rate of 4.97%, will reprice. The Company's net interest margin and spread decreased during the third quarter ended September 30, 2003 to 2.57% and 2.11%, respectively when compared to 3.22% and 2.69%, respectively for the same period in 2002. Cumulative through October 17, 2003, 607,687 convertible trust preferred shares were converted into 663,371 shares of the Company's common stock. The total convertible trust preferred shares converted to date represents 35.9% of the convertible trust preferred issue. During the nine months ended September 30, 2003, 297,705 convertible trust preferred shares were converted into 330,953 shares of the Company's common stock. During the third quarter ended September 30, 2003, 121,105 convertible trust preferred shares were converted into 136,256 shares of the Company's common stock. During the third quarter and nine months, the Company repurchased 62,000 and 221,800 shares, respectively of common stock at an average dollar price of $17.15 and $17.27, respectively.
