EXHIBIT 99.1 SOUTHSIDE BANCSHARES, INC. ANNOUNCES SECOND QUARTER EARNINGS NASDAQ NATIONAL MARKET SYMBOL - "SBSI" Tyler, Texas (July 18, 2003) B. G. Hartley, Chairman and Chief Executive Officer of Southside Bancshares, Inc., reported financial results for the second quarter and six months ended June 30, 2003. "We are pleased to report net income increased $657,000 or 10.7% to $6,784,000 for the six months ended June 30, 2003 compared to $6,127,000 for the same period in 2002," stated B. G. Hartley. Net income increased $66,000 or 2.0% to $3,427,000 for the second quarter ended June 30, 2003 compared to $3,361,000 for the same period in 2002. Earnings per diluted share were $0.68 and $0.62 for the six months ended June 30, 2003 and 2002, respectively, an increase of $0.06 or 9.7%. Earnings per diluted share were $0.34 for the second quarters ended June 30, 2003, and 2002. "We are also pleased to report Southside Bancshares, Inc. was added as a member of the Russell 3000(R) Index June 30, 2003 when Frank Russell Company reconstituted its family of U.S. indexes. The addition of Southside Bancshares, Inc. to the Russell 3000(R) Index is a significant milestone for our Company. We are extremely pleased that Southside's market capitalization has increased to a level that Southside Bancshares, Inc. is now one of the 3000 largest United States stocks." Membership in Russell's 21 U.S. equity indexes is determined by objective rules, such as market capitalization rankings. Annual reconstitution of the Russell indexes captures the 3,000 largest U. S. stocks as of the end of May, ranking them by total market capitalization to create the Russell 3000. On July 11, 2003 the Board of Directors of Southside Bancshares, Inc., approved a 25% increase in the regular quarterly cash dividend for the remaining two quarters of 2003 to $0.10 per common share from $0.08 per common share. "The Company and its common stock are enjoying another solid year and increasing the cash dividend is a way to share these successes with our shareholders. Recent tax law changes also make it more advantageous for our shareholders to receive cash dividends and we are sensitive to their interests." The annualized return on average shareholders' equity for the six months ended June 30, 2003 was 16.07% compared to 17.20% for the same period in 2002. The annualized return on average assets was 1.03% for the six months ended June 30, 2003 compared to 0.97% for the same period in 2002. The increase in net income for the quarter ended June 30, 2003 was primarily attributable to an increase in noninterest income, excluding security gains, of $821,000 or 20.7%, and the increase in gains on the sales of available for sale securities of $589,000 or 73.7%. Noninterest income, excluding security gains, increased primarily as a result of increased deposit fee income and fee income from the sale of mortgage loans. During the second quarter, long duration municipal securities and selected low yielding premium mortgage-backed securities were sold, and replaced with better call protected municipals and mortgage-backed securities with specific characteristics or coupons in an attempt to reduce prepayments. At June 30, 2003, the unrealized gain on available for sale securities was $8.9 million, net of tax, as compared to $9.3 million, net of tax, at December 31, 2002. These increases in noninterest income during the second quarter ended June 30, 2003 were partially offset by an increase in noninterest expense of $812,000, or 9.3%, and a decrease in net interest income of $567,000, or 6.7%. Noninterest expense increased as a result of salary increases for 2003, increased benefit costs and new branches opened during 2002. Net interest income decreased as a result of decreases in the Company's net interest margin and spread during the second quarter of 2003 when compared to the same period in 2002, which was due in part to lower mortgage interest rates and the lower overall interest rate environment. This led to substantially increased residential mortgage refinancing nationwide and in the Company's market area combined with substantially increased repricing of all of the Company's other loan types. Increased prepayments associated with the Company's mortgage-backed securities, residential mortgage loans and the substantial increase in repricing of other loan types may continue to impact the Company's net interest margin during the third quarter of 2003 or until overall interest rates increase. This may be offset by several factors including new deposit repricing strategies fully implemented during the second quarter, $61.5 million of fixed rate FHLB advances currently at an average rate of 4.42% that will reprice during the last two quarters of 2003 and continued fee income from the sale of mortgage loans into the secondary market due to the volume of refinancing that the Company is currently handling in its market area. The Company's net interest margin and spread increased slightly during the second quarter ended June 30, 2003 to 2.87% and 2.37%, respectively when compared to 2.80% and 2.30%, respectively for the first quarter ended March 31, 2003. Cumulative through July 15, 2003, 515,295 convertible trust preferred shares were converted into 556,703 shares of the Company's common stock. The total convertible trust preferred shares converted to date represents 30.4% of the convertible trust preferred issue. During the six months ended June 30, 2003, 176,600 convertible trust preferred shares were converted into 194,697 shares of the Company's common stock. During the second quarter ended June 30, 2003, 146,400 convertible trust preferred shares were converted into 161,403 shares of the Company's common stock. The Company expects to continue its $3.0 million stock repurchase plan for 2003. During the second quarter and six months, the Company repurchased 128,500 and 159,800 shares, respectively of common stock at an average dollar price of $17.31 and $17.32, respectively. The Company has approximately $0.2 million remaining to repurchase stock under the current Board approved level. At June 30, 2003, assets totaled $1.4 billion compared to $1.3 billion at June 30, 2002, an increase of $74.4 million or 5.7%. Net loans increased $24.1 million or 4.4% from $546.4 million at June 30, 2002 to $570.5 million at June 30, 2003. Investment and mortgage-backed securities increased $53.9 million or 8.5% from $632.5 million at June 30, 2002 to $686.4 million at June 30, 2003.
