First Security Group, Inc. Reports 2Q 2006 Net Income of $2.8 Million, Up 48.6 Percent from 2Q 2005


CHATTANOOGA, Tenn., July 25, 2006 (PRIMEZONE) -- First Security Group, Inc. (Nasdaq:FSGI), a community bank holding company serving middle and eastern Tennessee and northern Georgia, today reported results for the second quarter and first six months of 2006. Net income for the second quarter of 2006 was $2.8 million, an increase of 48.6 percent above the $1.9 million reported for the prior-year period. Diluted net income per share was $0.16 compared with $0.15 reported for the 2005 second quarter, an increase of 6.7 percent. The financial results of 2006 include the assets, liabilities and results of operations for Jackson Bank & Trust (Jackson Bank), which was acquired by First Security on August 31, 2005. Per share results also reflect the impact of First Security's stock offering of 4.9 million shares in the third quarter of 2005; average diluted shares for the second quarter of 2006 increased by 4,745,000, or 36.5 percent, above last year's second quarter.

For the first six months of 2006, First Security reported net income of $5.3 million, an increase of 76.3 percent from the $3.0 million reported in the prior-year period. Diluted net income per share was $0.30, an increase of 30.4 percent from the first six months of 2005.

Highlights of the second quarter include:



 -- Net operating income for the second quarter of 2006 rose 
    59.5 percent compared to the same period in 2005.  Diluted net 
    operating income per share increased 14.3 percent, from $0.14 to 
    $0.16.  For the six months year-to-date, net operating income rose 
    84.2 percent; diluted net operating income per share was up 
    36.4 percent, from $0.22 to $0.30. 2005 net operating income 
    excluded non-recurring income net of taxes of $129,000.
 
 -- Comparing the second quarter of 2006 to the linked first quarter, 
    net income rose 13.8 percent and diluted net income per share rose 
    $0.02, or 14.3 percent.
 
 -- For the six months year-to-date, performance reflects a stronger 
    net interest margin, up 7 basis points, to 5.27 percent; a 
    480 basis point improvement in the core efficiency ratio, to 
    65.25 percent; and higher profitability, as evidenced by the 
    operating return on average assets of 1.00 percent, up 28 basis 
    points.
 
 -- Total assets grew $258.1 million, or 31.0 percent, over the last 
    twelve months to $1.1 billion; excluding the assets of Jackson 
    Bank, organic growth was $71 million, or 8.6 percent. 
    Year-to-date, asset growth, all of it organic, was $48.6 million, 
    or 4.7 percent.
 
 -- Asset quality improved, as evidenced by a lower level of net 
    charge-offs and nonperforming assets.  For the first half of 2006, 
    annualized net charge-offs were 0.26 percent of average loans 
    compared with 0.37 percent for the prior-year period; 
    nonperforming assets at June 30, 2006 declined to 0.52 percent of 
    assets, a 29 basis point improvement from the year-ago level.

Rodger B. Holley, Chairman, President and CEO of First Security, commented, "Our second quarter and six-month performance reflects the momentum we have achieved as we continue to implement a strategy based on personalized sales and service. We anticipate an excellent year based on quarterly improving trends in virtually every category, including net interest margin, efficiency ratio, profitability and asset quality, as well as strong loan and deposit growth. Second quarter performance demonstrates the strength of our markets and our strategy."

Total revenue, comprised of net interest income and non-interest income, was $14.8 million for the second quarter of 2006, an increase of 25.4 percent over the $11.8 million reported for the second quarter of 2005. Net interest income increased 28.9 percent over the prior-year period, reaching $12.2 million; year-over-year growth reflects the combination of a 28.5 percent increase in average earning assets and a 5 basis point improvement in net interest margin to 5.27 percent. Compared with the first quarter of 2006, the second quarter margin remained consistent at 5.27 percent.

Non-interest income for the second quarter of 2006 was $2.7 million, an 11.6 percent increase above the $2.4 million earned in the second quarter of 2005. Excluding non-recurring income of $427,000 reported in the second quarter of 2005, non-interest income increased 36.0 percent. Service charges on deposit accounts increased $249,000, or 25.9 percent, primarily due to the Jackson Bank acquisition which contributed $200,000 for the second quarter of 2006. All other sources of non-interest operating income increased by $456,000, or 45.7 percent, due to improvements in the following categories: earnings from bank-owned life insurance, up $120,000; gains on sales of assets, up $104,000; point-of-sale fees, up $67,000; and trust fee income, up $66,000. Compared with first quarter, non-interest income rose $230,000, or 9.4 percent, primarily from a $58,000, or 5.0 percent, increase in service charges and a $150,000, or 58.1 percent, increase in mortgage fees.

Non-interest expense for the second quarter was $10.1 million, an increase of $1.9 million, or 22.7 percent, over the $8.2 million reported in the second quarter of 2005. Excluding non-recurring expense of $238,000 taken in the second quarter of 2005, non-interest operating expense rose $2.1 million, or 26.4 percent, from the year-ago quarter. The increase primarily reflects additional investment to support corporate growth, and the inclusion of Jackson Bank expenses. On a linked quarter basis, operating expenses increased $37,000; growth was moderated by a $99,000 decline in salaries and benefits expense resulting from a reduction of six FTE employees year-over-year, to 355 at period-end.

As a result of both revenue growth and expense control, the core efficiency ratio improved to 64.45 percent for the second quarter of 2006 compared with 68.60 percent for the prior-year period, and 66.07 percent for the linked quarter. Mr. Holley commented, "We have been successful with our integration initiatives, yet we believe there are still additional economies to be realized. Even with a new headquarters building and an active branch expansion strategy, we are still comfortable with our 3-year core efficiency goal of 60 percent."

Asset quality improves with each quarter. Net charge-offs for the current quarter were $468,000, or 0.24 percent of average loans on an annualized basis, compared with $531,000, or 0.28 percent of average loans for the linked quarter, and $544,000, or 0.35 percent of average loans for the second quarter of 2005. Non-performing assets plus delinquencies were $5.7 million at June 30, 2006, which relative to portfolio size remains strong and continues to represent a significant improvement over 2005: 0.52 percent of total assets at June 30, 2006, compared with 0.51 percent of total assets at March 31, 2006, and 0.81 percent of total assets twelve months ago. Loan loss reserves were 1.28 percent of total loans at June 30, 2006.

Total assets were $1.1 billion at June 30, 2006, an increase of $258.1 million, or 31.0 percent above year-earlier levels. Loan growth was $176.2 million, or 28.2 percent over the twelve-month period, with Jackson Bank contributing approximately $104.3 million, or 59.2 percent of this growth. Excluding Jackson Bank, loan growth was $71.9 million, or 11.5 percent, year-over-year. The loan categories with the largest increases over the past twelve months were: construction & land development, up $45.2 million or 47.5%, to $140.2 million, of which $33.7 million was organic; commercial real estate, up $29.5 million or 20.9%, to $170.5 million, of which $15.8 million was organic; and residential mortgage loans, up $66.6 million or 41.6 percent, to $226.8 million, of which $11.3 million was organic.

For the first half of the year, loans grew $51.6 million or 6.9 percent, with approximately 65.2 percent of the growth occurring in the second quarter. Commercial real estate accounted for $12.8 million, up 8.1 percent, with virtually all of this growth occurring in the second quarter. Construction and land development loans, up $19.8 million for the half year, or 16.4 percent, slowed slightly in the second quarter.

Deposits were $907.4 million at June 30, 2006, up $199.3 million, or 28.2 percent, over the last twelve months; Jackson Bank contributed approximately $140.2 million, or 70.3 percent of total deposit growth. Excluding Jackson Bank, total deposits grew $59.1 million, or 8.4 percent. Core deposits (demand, savings, money market and retail time deposits) were $637.2 million at June 30, 2006, up 28.2 percent year-over-year; they comprised 70.2 percent of total deposits for both the current and year-ago quarters. Deposits increased $24.9 million, or 2.8 percent from the linked quarter, of which $12.7 million consisted of core deposits. On a year-over-year basis, non-interest bearing demand deposits outpaced total deposit growth, increasing to 19.6 percent of deposits from 18.3 percent a year ago. Brokered deposits, primarily used to match fund First Security's leasing portfolio, were $86.7 million, or 9.6 percent of the deposit portfolio.

Shareholders' equity at June 30, 2006 was $137.8 million, a twelve-month increase of $48.6 million, or 54.4 percent. The majority of this increase reflects $44.7 million in proceeds from the issuance of 4.9 million shares during the third quarter of 2005. Total shares outstanding at quarter-end were 17,934,000. First Security's tangible leverage ratio at quarter-end was 10.0 percent. Mr. Holley concluded, "Our performance for the first half of 2006 provides a solid foundation for continued growth and greater profitability. We believe these positive trends should have a favorable impact on shareholder value, serving to reward investors for their confidence in First Security Group."

Non-GAAP Financial Measures

This press release contains financial information determined by methods other than in accordance with generally accepted accounting principles in the United States of America ("GAAP"). First Security's management uses these "non-GAAP" measures in their analysis of First Security's performance. Non-GAAP measures typically adjust GAAP performance measures to exclude the effects of charges, expenses and gains related to the consummation of mergers and acquisitions, and costs related to the integration of merged entities. These non-GAAP measures may also exclude other significant gains, losses or expenses that are unusual in nature and not expected to recur. Since these items and their impact on First Security's performance are difficult to predict, management believes presentations of financial measures excluding the impact of these items provide useful supplemental information that is important for a proper understanding of the operating results of First Security's core business. These disclosures should not be viewed as a substitute for operating results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies.

Forward-Looking Statements

This news release contains comments or information that constitute forward-looking statements (within the meaning of the Private Securities Litigation Reform Act of 1995) that are based on current expectations that involve a number of risks and uncertainties. Actual results may differ materially from the results expressed in forward-looking statements. Factors that might cause such a difference include changes in interest rates and interest rate relationships; demand for products and services; the degree of competition by traditional and non-traditional competitors; changes in banking regulation; changes in tax laws; changes in prices, levies, and assessments; the impact of technological advances; governmental and regulatory policy changes; the outcomes of contingencies; trends in customer behavior as well as their ability to repay loans; changes in the national and local economy; and other factors, including risk factors, referred to from time to time in filings made by First Security with the Securities and Exchange Commission.

 (a) These ratios are calculated using net income, before
     extraordinary items.

 (b) These amounts and ratios are calculated using net operating
     income (net of tax) which excludes extraordinary items as defined
     by GAAP and certain non-recurring items. Since these items and
     their impact on First Security's performance are difficult to
     predict, management believes presentation of financial measures
     excluding the impact of these items provide useful supplemental
     information that is important for a proper understanding of the
     operating results of First Security's core business. Refer to the
     following non-GAAP reconciliation table for a detail of the
     non-recurring items.

 (c) In accordance with SNL Financial practice, the core efficiency
     ratio is calculated on a fully tax equivalent basis excluding
     non-recurring items (see footnote (2) and non-GAAP reconciliation
     table) and certain non-cash items, such as amortization of
     intangibles, gains or losses on investment securities and gains,
     losses and write-downs on foreclosed and repossessed properties.
