Exhibit 99.1

 International Shipholding Corporation Reports Second Quarter Results


    NEW ORLEANS, La.--(BUSINESS WIRE)--July 27, 2005--International
Shipholding Corporation (NYSE: ISH) today reported results for the
three month and six month periods ended June 30, 2005. Net income for
the three months ended June 30, 2005 was $3.973 million as compared to
$1.828 million for the three months ended June 30, 2004. For the first
six months of 2005, net income was $8.066 million as compared to
$4.725 million for the same period of 2004. Net income available to
common stockholders for the second quarter and six month period ended
June 30, 2005 was $3.373 million and $6.899 million, respectively,
after dividends on the Company's preferred stock issue.
    Improvement in the current quarter resulted primarily from the
results of our two container vessels, acquired in December of 2004 and
subsequently chartered-out; full utilization of our U.S. Flag Coal
Carrier which experienced out of service time in the second quarter of
2004; higher volume of supplemental cargoes on our U.S. flag
PureCar/Truck Carriers; a gain from a sale of some of our LASH barges
of $540,000; and a lower effective tax rate under the Jobs Creation
Act (as discussed below).
    The improvements in the quarter were partially offset by lower
results from our foreign flag TransAtlantic LASH and our Mexican
Rail/Ferry services. The foreign flag LASH service experienced an
increase in operating costs and weather delays while the Mexican
Rail/Ferry service was temporarily disrupted in the quarter because of
delays caused while moving the operations from Mobile, Alabama, to New
Orleans, Louisiana.
    Depreciation expense was higher in the current quarter due to the
addition of the two container vessels. Administrative and general
expenses were higher in the current quarter primarily due to wage and
benefit increases and higher fees for professional services.
    In addition to the aforementioned, the improved results for the
six month period included a before tax gain of $1.225 million from our
share on the sale of a cement carrier vessel in the first quarter of
2005.
    As a result of the tonnage tax treatment of our U.S. flag
international operations under the 2004 American Jobs Creation Act,
our effective federal tax rate on earnings before equity in net income
of unconsolidated entities was 3.9% and 7.8%, respectively, for the
quarter and six month period ended June 30, 2005. Our comparable 2004
quarter and six month periods reflected effective federal tax rates of
38.9% and 37.7%, respectively.
    Net income available to common stockholders for the 2005 quarter
and six month periods is after dividends on our $40 million of 6%
Convertible Exchangeable Preferred Stock. The preferred stock, which
has a liquidation preference of $50 per share, accrues cumulative
quarterly cash dividends from the date of issuance at a rate of 6% per
annum.
