Commission File No. 333-63212 SOUTHSIDE BANCSHARES CORP. NEWS RELEASE ------------------------------------------------------------------------------- NEWS FOR IMMEDIATE RELEASE Contact: Joseph W. Pope Traded: NASDAQ/SCM (314) 416-4111 or Symbol: SBCO (314) 845-5618 SOUTHSIDE ANNOUNCES EARNINGS St. Louis, July 17, 2001 - Thomas M. Teschner, President and CEO of Southside Bancshares Corp. (the "Company") announced today that the Company's net income for the first half and second quarter of 2001 was $2,744,000 and $1,191,000, respectively, compared to $3,333,000 and $1,659,000 for the comparable periods in 2000. These earnings resulted in diluted earnings per share of $.32 and $.14, respectively in 2001, versus $.39 and $.19, respectively in 2000. The decline in both the first half and second quarter earnings can largely be attributed to professional fees and other expenses relating to the pending merger with Allegiant Bancorp, Inc. ("Allegiant"). As previously announced on May 1, 2001, the Company has signed a definitive agreement for a merger with Allegiant. The merger, which is still subject to regulatory and shareholder approval, is expected to close in the fourth quarter of this year. Under the terms of the agreement, Southside shareholders will receive 50% of the merger consideration in the form of cash of $14.00 per share and 50% in the form of 1.39 shares of Allegiant common stock for each share of Southside common stock. Following the merger, the combined entity should have total assets of approximately $2 billion, total loans of approximately $1.3 billion and total deposits of 2 approximately $1.5 billion. Excluding the costs directly related to the merger, net income for the first half of 2001 would have been $3,204,000 and would have resulted in diluted earnings per common share of $.38 and net income for the second quarter would have been $1,651,000 and would have resulted in diluted earnings per common share of $.19. "Excluding the effects of the merger related expenses, the Company's operating results for the second quarter and first half of 2001 would have been only slightly behind the prior year. This decline was the result of the falling interest rate environment during 2001, which caused the Company's assets to reprice at lower rates more rapidly than our deposits. The Company expects that this trend should begin to reverse itself over the next several periods," stated Mr. Teschner. Southside Bancshares Corp. is a $775 million bank holding company with four subsidiary banks, including South Side National Bank in St. Louis, State Bank of Jefferson County, Bank of Ste. Genevieve and The Bank of St. Charles County, which operates sixteen banking locations in Missouri.
