        MIDSOUTH BANCORP, INC. ANNOUNCES SECOND QUARTER EARNINGS RESULTS

    LAFAYETTE, La., July 24 /PRNewswire-FirstCall/ -- MidSouth Bancorp, Inc.
(Amex: MSL) announced earnings of $2,235,000 for the quarter ended June 30,
2006, a 9.6% increase over earnings of $2,040,000 for the same period in 2005,
and a 22.9% increase over the quarter ended March 31, 2006. Basic earnings per
share were $.45 for the quarter ended June 30, 2006, compared to $.42 per share
reported for the second quarter of 2005, and $.37 per share earned in the first
quarter of 2006. Diluted earnings per share were $.44 for the second quarter of
2006, compared to $.40 per share for the second quarter of 2005 and $.36 for the
first quarter of 2006.

    For the first six months of 2006, MidSouth Bancorp earned $4,054,000, a 2.3%
increase over the $3,964,000 reported for the first six months of 2005. Basic
earnings per share were $.82 for the first half of 2006 versus $.81 per share
for the first half of 2005. Diluted earnings per share were $.80 versus $.78,
respectively. The first six months of 2005 included a $631,000 pre-tax special
distribution of proceeds to the Company from the merger of Pulse EFT Association
and Discover Financial Services, Inc. Additionally, the first six months of 2005
included a $102,000 pre-tax write-down of a branch facility. Excluding the
$349,000 after-tax effect of these non-recurring transactions, the Company's
year-to-date earnings for 2006 improved by $439,000, or 12%, over 2005.

    Highlights for the Quarter Ended June 30, 2006

     * Return on average equity was 16.48% for the second quarter of 2006
       compared to 16.26% for the second quarter of 2005. The leverage capital
       ratio was 8.32% at June 30, 2006, compared to 9.15% at June 30, 2005.

     * Net interest income totaled $8,295,000 for the second quarter of 2006, up
       21.0% from the $6,857,000 reported for the second quarter of 2005. Net
       interest income increased primarily due to a 22.3% increase in the
       average volume of earning assets, including a 16.0% increase in average
       loan volume. Additionally, the average yield on earning assets improved
       75 basis points, from 6.80% for the second quarter of 2005 to 7.55% for
       the second quarter of 2006. The impact of the improvement in average
       earning asset volume and yield was partially offset by volume and rate
       increases in interest-bearing liabilities.

     * Total consolidated assets increased $148.0 million, or 23.4%, from $631.9
       million at the end of the second quarter of 2005 to $779.9 million at the
       end of the second quarter of 2006.

     * Total loans grew $79.5 million, or 19.4%, from $410.0 million at June 30,
       2005 to $489.5 million at June 30, 2006, primarily in commercial and real
       estate credits.

     * Nonperforming assets, including loans 90 days or more past due, totaled
       $2.7 million at June 30, 2006, compared to $2.3 million at June 30, 2005.
       As a percentage of total assets, nonperforming assets were .35% and .36%
       for June 30, 2006 and 2005, respectively. Included in nonperforming
       assets for June 30, 2006, is approximately $1.6 million in
       government-guaranteed loans. Net charge-offs to total loans decreased to
       .02% for the second quarter of 2006 compared to .05% for the second
       quarter of 2005. Allowance for loan loss provisions totaling $300,000
       were taken in the second quarter of 2006 compared to $66,000 in the
       second quarter of 2005. As a percentage to total loans, the allowance for
       loan losses for the quarters ended June 30, 2006 and 2005 were 1.00% and
       .99%, respectively. The Company has not experienced an increase in
       delinquencies or charge-offs due to Hurricanes Katrina and Rita.

     * Total deposits increased $145.4 million, or 26.0%, from $558.7 million at
       June 30, 2005 to $704.1 million at June 30, 2006. Deposit growth has been
       primarily in the Company's Platinum money market and checking accounts,
       which represent 31.5% of total deposits at June 30, 2006. The Platinum
       money market and checking accounts offer competitive rates of interest
       that adjust to changes in market rates. Additionally, the core
       non-interest bearing demand accounts have continued to grow and represent
       26.5% of total deposits at June 30, 2006.



    Components of Second Quarter Earnings

    Net interest income for the second quarter of 2006 increased $1.4 million,
or 21.0%, compared to the second quarter of 2005 due to a 22.3% increase in the
average volume of earning assets and a 75 basis point improvement in the average
yield on earning assets. Average loan volume increased $64.4 million and the
average yield on loans increased 107 basis points, from 7.81% in the second
quarter of 2005 to 8.88% in the second quarter of 2006. The improvement in
interest income was partially offset by increased interest expense resulting
from a $94.7 million increase in the average volume of interest-bearing deposits
and a 110 basis point increase in the average cost of interest-bearing deposits,
from 2.07% in the second quarter of 2005 to 3.17% in the second quarter of 2006.
The taxable-equivalent net yield on earning assets decreased 4 basis points in
quarterly comparison, from 5.04% in the second quarter of 2005 to 5.00% in the
second quarter of 2006.

    Non-interest income for the second quarter of 2006 decreased $99,000
compared to the second quarter of 2005, primarily due to $93,000 in Pulse
proceeds received in the second quarter of 2005.

    Non-interest expense increased $882,000, or 12.3%, in quarterly comparison,
primarily due to a $632,000, or 19.1%, increase in salaries and employee
benefits associated with an increase in the number of full-time equivalent
employees from 305 in June 2005 to 349 in June 2006. Staffing for five new
retail offices added over the past twelve months contributed to the increase in
salaries and benefit costs. The additional retail offices also contributed to a
$295,000, or 22.2%, increase in occupancy expenses in quarterly comparison.

    In linked-quarter comparison, earnings increased $416,000, or 22.9%, from
$1,819,000 for the quarter-ended March 31, 2006 to $2,235,000 for the quarter-
ended June 30, 2006. Volume and rate increases in earning assets drove
improvement in net interest income of $898,000 and non-interest income increased
$228,000. The increased net interest income and non-interest income was
partially offset by increased non-interest expenses of $573,000.

    Year-to-Date Earnings and Franchise Growth

    In year-to-date comparison, net of the $349,000 after-tax effect of the
Pulse proceeds and the branch write-down, earnings increased $439,000. Net
interest income for the six months ended June 30, 2006, increased $2.4 million
or 18.1% compared to the six months ended June 20, 2005. The $2.4 million
improvement in net interest income was mostly offset by a $1.4 million, or
10.1%, increase in non-interest expenses combined with a $240,000 increase in
the provision for loan losses in year-to-date comparison. The increased non-
interest expenses reflect the Company's investment in executing its plan to grow
the franchise.

    In addition to the five retail offices opened over the past twelve months,
six new offices are scheduled to open through mid-year 2007. Two retail stores
are planned for the Baton Rouge market and scheduled to open in the first half
of 2007. A new retail store in Thibodaux is under construction and a second
store in Lake Charles is scheduled to begin construction in the fourth quarter
of 2006. In the Texas markets, a full service retail store location for the
Conroe, Texas market is scheduled to open in April 2007 and management is
working on site selection for a full service retail store in the College Station
market. Costs associated with opening these six new stores will continue to
impact earnings throughout 2006 and any substantial contributions to income will
not be reflected until the second half of 2007.
