Exhibit 99.1 SOUTHSIDE BANCSHARES, INC. ANNOUNCES FIRST QUARTER EARNINGS TYLER, Texas, April 19 /PRNewswire-FirstCall/ -- Southside Bancshares, Inc. (Nasdaq: SBSI) ("Southside" or the "Company") reports financial results for the three months ended March 31, 2007. Net income increased 16.6%, or $535,000, for the three months ended March 31, 2007, to $3.8 million from $3.2 million for the same period in 2006. B. G. Hartley, Chairman and Chief Executive Officer, stated, "We are pleased with Southside's first quarter results. This provides an excellent foundation on which to build during 2007. 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 three de novo branches since December 31, 2005, and the increasingly challenging interest rate environment experienced during 2006 as noninterest income, excluding gain on sale of securities available for sale, increased $734,000, or 14.8% for the three months ended March 31, 2007 when compared to the same period in 2006, while for the same periods noninterest expense decreased $198,000, or 1.7%." Earnings per fully diluted share increased $0.04, to $0.29 for the three months ended March 31, 2007, or 16.0%, when compared to $0.25 for the same period in 2006. The return on average shareholders' equity for the three months ended March 31, 2007 was 13.55%, compared to 11.79%, for the same period in 2006. The annual return on average assets was 0.81%, for the three months ended March 31, 2007, compared to 0.72%, for the same period in 2006. Loan and Deposit Growth The Company continued to experience loan growth during the three months ended March 31, 2007, as loans increased $7.2 million, or 1.0%, to $766.4 million from $759.1 million at December 31, 2006. Loan growth during 2007 occurred primarily in construction loans, consumer loans, and commercial loans. The consistent growth in loans is significant given the increasing competition in the Texas banking markets we serve. Additionally, the 2007 loan growth was accompanied by a 18.7% 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 remains to become the primary financial provider for these account holders, thereby creating value from within." During the three months ended March 31, 2007, deposits increased a solid $26.9 million, or 2.1%, to $1.31 billion from $1.28 billion at December 31, 2006. The overall growth in deposits during the first quarter ended March 31, 2007 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. Callable-brokered certificates of deposits with long- term maturities, where the Company controls numerous call options, at March 31, 2007 totaled $123.4 million compared to $123.5 million at December 31, 2006. We believe these callable-brokered CDs continue to offer the Company significant long-term flexibility. Net Interest Income Net interest income decreased $543,000, or 5.1%, to $10.0 million for the three months ended March 31, 2007, when compared to $10.6 million for the same period in 2006. The net interest margin and net interest spread were impacted by the significant increase in short-term interest rates during 2006 combined with significantly smaller increases in long-term interest rates. This resulted in an inverted yield curve for most of 2006 and the first three months of 2007, 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 2.47% and 1.67%, respectively, for the three months ended March 31, 2007 compared to 2.72% and 2.08%, respectively, for the same period in 2006. When comparing the first quarter ended March 31, 2007 to the fourth quarter ended December 31, 2006, the Company's net interest margin and spread increased slightly to 2.47% and 1.67%, respectively, from 2.45% and 1.65%, respectively, for the fourth quarter of 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 March 31, 2007 was primarily attributable to an increase in noninterest income, a decrease in noninterest expense and a decrease in provision for loan losses. Noninterest income, excluding gain on sale of available for sale securities, increased $734,000, or 14.8%, for the three months ended March 31, 2007, compared to the same period in 2006. The increase in noninterest income was primarily the result of increases in deposit services income, trust income, and other income. Provision for loan losses decreased $164,000, or 58.4%, for the three months ended March 31, 2007, compared to the same period in 2006. Noninterest expense decreased $198,000, or 1.7%, for the three months ended March 31, 2007, compared to the same period in 2006. The decrease in noninterest expense was primarily a result of a decrease in salaries and employee benefits of $316,000, or 4.3%, for the three months ended March 31, 2007, compared to the same period in 2006. In addition to the decrease in net interest income discussed above, partially offsetting the increase in net income, Federal income tax expense increased $324,000, or 44.8%, for the three months ended March 31, 2007, when compared to the same period in 2006. 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 March 31, 2007, when compared to the same period in 2006.
