Exhibit 99.1 SOUTHSIDE BANCSHARES, INC. ANNOUNCES AN INCREASE IN FOURTH QUARTER AND ANNUAL EARNINGS TYLER, Texas, Jan. 25 /PRNewswire-FirstCall/ -- Southside Bancshares, Inc. (Nasdaq: SBSI) ("Southside" or the "Company") reports financial results for the three months and year ended December 31, 2006. Net income increased 19.8%, or $692,000 for the three months ended December 31, 2006, to $4.2 million from $3.5 million for the same period in 2005. For the year ended December 31, 2006, net income increased $410,000, or 2.8% to $15.0 million when compared to $14.6 million for the same period in 2005. B. G. Hartley, Chairman and Chief Executive Officer, stated, "Southside had an excellent and especially gratifying year during 2006. Our success in achieving these results was due to the significant progress we made on a number of previously discussed key initiatives, intended to increase revenues and contain costs. The success of the initiatives more than offset the additional operating expenses associated with opening four de novo branches since September 30, 2005, and the increasingly challenging interest rate environment experienced during 2006." Earnings per fully diluted share increased 22.2%, or $0.06 and 2.6%, or $0.03 for the three months and year ended December 31, 2006, to $0.33 and $1.18, respectively, when compared to $0.27 and $1.15 for the same periods in 2005. The return on average shareholders' equity for the three months and year ended December 31, 2006 were 14.11% and 13.48%, respectively, compared to 13.05% and 13.88%, respectively, for the same periods in 2005. The annual return on average assets were 0.88% and 0.81%, respectively, for the three months and year ended December 31, 2006, compared to 0.79% and 0.86%, respectively, for the same periods in 2005. Loan and Deposit Growth The Company continued to experience solid loan growth during the three months ended December 31, 2006, as loans increased $17.6 million, or 2.4%, to $759.1 million from $741.5 million at September 30, 2006. During the year ended December 31, 2006, Southside experienced strong loan growth as loans increased $78.8 million, or 11.6%, to $759.1 million from $680.4 million at December 31, 2005. Loan growth during 2006 has occurred primarily in commercial loans, 1-4 family residential loans, and commercial real estate loans. The consistent growth in loans is significant given the increasing competition in the Texas banking markets we serve. Additionally, the 2006 loan growth was accompanied by a 31.0% decrease in nonperforming assets. Commenting on the loan growth, B. G. Hartley said, "Our marketplace in Texas has continued to expand over the past several years through the opening of branches in strategic market areas. Positioning for future success, with de novo branching a key element, remains a central part of our business strategy. In addition to the loan and deposit growth, another critical portion of Southside's business strategy is the focus on increasing the number of accounts and relationships. Continued growth in the number of deposit accounts should provide Southside significant opportunities to enhance fee income. Our goal is to become the primary financial provider for these account holders, thereby creating value from within by utilizing this additional organic growth source. During the three months ended December 31, 2006, deposits increased $71.6 million, or 5.9%, to $1.28 billion from $1.21 billion at September 30, 2006. During the year ended December 31, 2006, the Company's deposits increased $171.7 million, or 15.5% to $1.28 billion from $1.11 billion at December 31, 2005. Approximately $68.0 million of the overall growth in deposits during 2006 resulted from our expanding branch network and continued market penetration. Price related competition for deposits has intensified. While the Company has attempted to maintain a disciplined deposit pricing strategy, the current competitive environment could pressure the net interest margin in the coming quarters. The remaining $103.7 million of the deposit growth was the result of the Company issuing callable-brokered certificates of deposits with long-term maturities where the Company controls numerous call options. Brokered deposits at December 31, 2006 totaled $123.5 million compared to $19.8 million at December 31, 2005. We believe these callable-brokered CDs offer the Company significant long-term flexibility. Net Interest Income Net interest income decreased $81,000, or 0.8% to $10.2 million for the three months ended December 31, 2006, when compared to $10.3 million for the same period in 2005. The net interest margin and net interest spread were impacted by the significant increase in short-term interest rates during 2005 and 2006 combined with significantly smaller increases in long-term interest rates. This resulted in an inverted yield curve, where short-term interest rates were higher than long-term interest rates. As a result, the Company's net interest margin and net interest spread decreased to 2.45% and 1.65%, respectively, for the three months ended December 31, 2006 compared to 2.72% and 2.13%, respectively, for the same period in 2005 and 2.51% and 1.75%, respectively, for the three months ended September 30, 2006. Should the yield curve remain inverted or invert more, the Company's net interest margin and spread could come under additional pressure during 2007. Net Income for the Three Months The increase in net income for the three months ended December 31, 2006 was primarily attributable to an increase in noninterest income and a decrease in provision for loan losses. Noninterest income, excluding gain on sale of available for sale securities, increased $721,000, or 13.7%, for the three months ended December 31, 2006, compared to the same period in 2005. The increases in noninterest income were primarily results of increases in deposit services income, trust income, gain on sale of loans, and other income. Provision for loan losses decreased $391,000, or 75.8%, for the three months ended December 31, 2006, compared to the same period in 2005. Partially offsetting the increase in net income, Federal income tax expense increased $497,000, or 63.8%, for the three months ended December 31, 2006, when compared to the same period in 2005. Federal income tax expense increased as a result of the decrease in tax-exempt income as a percentage of pre-tax income for the three months ended December 31, 2006, when compared to the same period in 2005. Net Income for the Year The increase in net income for the year ended December 31, 2006 was primarily attributable to an increase in net interest income, noninterest income and a decrease in provision for loan losses. Net interest income increased $409,000, or 1.0%, for the year ended December 31, 2006 when compared to the same period in 2005. Net interest income increased as a result of increases in the Company's average interest earning assets during the year ended December 31, 2006 when compared to the same period in 2005, which more than offset the decrease in the Company's net interest spread and margin during the same period. Noninterest income, excluding gain on sale of available for sale securities, increased $1.7 million, or 8.2%, for the year ended December 31, 2006, when compared to the same period in 2005. The increases in noninterest income were primarily results of increases in deposit services income, trust income, and other income. Gain on sale of securities available for sale increased $515,000, or 225.9%, for the year ended December 31, 2006 compared to the same period in 2005. Provision for loan losses decreased $383,000, or 26.2%, for the year ended December 31, 2006, compared to the same period in 2005. The following items partially offset the increase in net income for the year ended December 31, 2006, when compared to the same period in 2005. Noninterest expense increased $1.8 million, or 4.2%, for the year ended December 31, 2006, compared to the same period in 2005. Noninterest expense increased primarily as a result of increases in salary and employee benefits, occupancy expense, and ATM expense. Salaries and employee benefits increased $796,000, or 2.9%, during the year ended December 31, 2006, when compared to the same period in 2005, due to normal salary increases and higher staffing levels associated with the Company's continued branch expansion and regional lending initiative. Occupancy expense increased $520,000, or 12.2%, ATM expense increased $307,000, or 47.4%, and Federal income tax expense increased $807,000, or 24.5%, for the year ended December 31, 2006, when compared to the same period in 2005. Occupancy expense increased primarily due to branch expansion and Federal income tax expense increased as a result of the decrease in tax-exempt income as a percentage of pre-tax income for the year ended December 31, 2006 when compared to the same period in 2005.
