Exhibit 99.1 SOUTHSIDE BANCSHARES, INC. ANNOUNCES FIRST QUARTER EARNINGS TYLER, Texas, April 20 /PRNewswire-FirstCall/ -- B. G. Hartley, Chairman and Chief Executive Officer of Southside Bancshares, Inc. (Nasdaq: SBSI) ("Southside" or the "Company"), reported financial results for the first quarter ended March 31, 2006. For the three months ended March 31, 2006, the Company reported net income of $3,228,000, compared to $3,575,000 for the same period in 2005, a decrease of $347,000, or 9.7%. Earnings per fully diluted share were $0.25 for the three months ended March 31, 2006 compared to $0.28 for the same period in 2005. The return on average shareholders' equity for the first quarter ended March 31, 2006 was 11.79% compared to 13.81% for the same period in 2005. The annual return on average assets was 0.72% for the first quarter ended March 31, 2006, compared to 0.88% for the same period in 2005. Loan and Deposit Growth The Company experienced strong loan growth during the first quarter ended March 31, 2006, as loans increased $26.0 million, or 3.8%, to $706.4 million from $680.4 million at December 31, 2005. The loan growth during the first quarter occurred primarily in commercial real estate loans, 1-4 family residential loans, and commercial loans. Asset quality improved as non- performing assets decreased $194,000, or 6.3%, to $2.9 million at March 31, 2006, when compared to $3.1 million at December 31, 2005. We believe that the Company's asset quality ratios as reported in this earnings release remain sound. During the three months ended March 31, 2006, the Company experienced solid deposit growth, as deposits increased $77.2 million to $1.19 billion from $1.11 billion at December 31, 2005. We are gratified deposits continued to grow at an excellent pace during the first quarter with $23.1 million of that growth resulting from our expanding branch network and continued market penetration. The remaining $54.1 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 March 31, 2006 totaled $73.9 million. We believe these callable- brokered CDs offer the Company significant long-term flexibility. Branch Expansion Continues During the first quarter, Southside opened three banking centers. In February 2006, Southside opened a loan production office in the growing area of Forney, Texas, approximately 20 miles east of Dallas. In addition, the Company opened a full service branch in Gun Barrel City, Texas located next to a growing lake community southeast of Dallas. In March, the Company opened a full service branch in a grocery store in the city of Athens, Texas, west of Tyler. All three of these new branches should complement our expansion to the west of Tyler. The Company's ongoing investments in de novo branches has and will continue to impact short-term earnings, however, the Company believes the potential long-term benefits to the Company should greatly outweigh the initial costs. Net Interest Income Net interest income increased $190,000 to $10.6 million for the quarter ended March 31, 2006, when compared to $10.4 million for the same period in 2005. As is impacting all banks, some more than others, short-term yields increased significantly during 2005 while long-term yields increased less, creating what is called a flat yield curve, where short-term yields are relatively flat compared to long-term yields. The result for the Company was a reduction in the net interest margin and net interest spread to 2.72% and 2.08%, respectively, for the three months ended March 31, 2006 when compared to 2.98% and 2.50% for the same period in 2005. When comparing the first quarter ended March 31, 2006 to the fourth quarter ended December 31, 2005, the Company's net interest margin remained unchanged at 2.72% while the Company's net interest spread declined five basis points to 2.08% from 2.13%. Should the yield curve remain flat or invert, our net interest margin and spread could come under additional pressure during the remainder of 2006. Net Income The decrease in net income for the three months ended March 31, 2006, when compared to the same period in 2005, was primarily attributable to an increase in noninterest expense of $879,000, or 8.3% and an increase in provision for loan losses of $46,000, or 19.6%. Noninterest expense increased primarily as a result of a $562,000, or 8.2%, increase in salaries and employee benefits. The increase in salaries and employee benefits is due to normal salary increases and higher staffing levels associated with both the continued branch expansion and the Company's regional lending initiative. The following items partially offset the decrease in net income for the three months ended March 31, 2006, when compared to the same period in 2005. In addition to the increase in net interest income of $190,000, or 1.8%, to $10.6 million for the first quarter of 2006 as discussed above, the Company's gain on sale of securities increased $339,000 when comparing the first quarter of 2006 to the same period in 2005. Noninterest income, excluding gain on sale of securities, was flat for the first quarter of 2006, when compared to the first quarter of 2005. During the first quarter ended March 31, 2005, the Company received a $244,000 special distribution as a result of the merger of the Public EFT Association with Discover Financial Services. Not including this special distribution, noninterest income not including gain on the sale of securities, increased $246,000 for the first quarter 2006 when compared to the same period in 2005. The increase was primarily a result of an increase in deposit services income and Trust income. Provision for federal tax expense of $724,000 for the first quarter of 2006, decreased $47,000, from the first quarter of 2005 primarily as a result of a decrease in taxable income.
