               SEACOR HOLDINGS ANNOUNCES THIRD QUARTER RESULTS


Fort Lauderdale, Florida
October 25, 2007

FOR IMMEDIATE RELEASE -- SEACOR Holdings Inc. (NYSE:CKH) announced net income
for the third quarter ended September 30, 2007 of $70.3 million, or $2.66 per
diluted share, on operating revenues of $360.0 million. For the nine months
ended September 30, 2007, net income was $173.7 million, or $6.44 per diluted
share, on operating revenues of $996.1 million.

For the third quarter ended September 30, 2006, net income was $63.2 million, or
$2.28 per diluted share, on operating revenues of $349.4 million. For the nine
months ended September 30, 2006, net income was $176.0 million, or $6.32 per
diluted share, on operating revenues of $986.3 million.

For the preceding quarter ended June 30, 2007, net income was $65.3 million, or
$2.41 per diluted share, on operating revenues of $325.5 million.

HIGHLIGHTS FOR THE QUARTER

OFFSHORE MARINE SERVICES - Operating income in the third quarter was $70.3
million on operating revenues of $179.6 million compared to operating income of
$95.0 million on operating revenues of $171.4 million in the preceding quarter.
Third quarter results included $13.2 million in gains on asset dispositions
compared to $38.5 million in gains in the preceding quarter.

The number of days available for charter in the third quarter decreased 571, or
3.2% due to a net reduction in fleet count. Overall average day rates increased
from $10,948 to $11,769 per day. Overall utilization decreased from 84.0% to
83.6%.

Operating expenses in the third quarter were higher due to wage increases in the
North Sea region following an annual rate review and the addition of one new
vessel to the North Sea fleet. In the Far East region, additional costs were
incurred to charter-in third party vessels in order to provide cover for vessels
undergoing dockings. Additionally, during the third quarter SEACOR was invoiced
and recognized $3.9 million for its share of a funding deficit arising from the
March 2006 actuarial valuation of the United Kingdom Merchant Navy Officers
Pension Fund.

MARINE TRANSPORTATION SERVICES - Marine Transportation Services reported an
operating loss in the third quarter of $2.2 million on operating revenues of
$27.7 million compared to an operating loss of $8.0 million on operating
revenues of $25.9 million in the preceding quarter.

Operating results in the third quarter were positively impacted by the return to
service of a vessel which had recently undergone a retrofit to a double-hull
configuration. The vessel was on-hire for the entire third quarter as compared
to 23 days in the prior quarter.

Operating results in the third quarter were also affected by two vessels being
off-hire for various periods. One of these vessels was off-hire for the entire
quarter while undergoing a retrofit to a double-hull configuration and is
expected to return to service in the fourth quarter. The other vessel was
off-hire for 25 days in August 2007 while undergoing a regulatory docking.


                                       1




INLAND RIVER SERVICES - Operating income in the third quarter was $12.0 million
on operating revenues of $32.7 million compared to operating income of $11.2
million on operating revenues of $28.0 million in the preceding quarter. Third
quarter results included $1.6 million in gains on asset dispositions compared to
$2.6 million in gains in the preceding quarter.

The improvement in operating income before gains on asset dispositions was
generally due to higher freight rates, partially offset by higher towboat repair
and maintenance costs.

AVIATION SERVICES - Operating income in the third quarter was $13.5 million on
operating revenues of $62.4 million compared to operating income of $5.1 million
on operating revenues of $55.9 million in the preceding quarter. Third quarter
results included $4.3 million in gains on asset dispositions compared to $1.5
million in gains in the preceding quarter.

The improvement in operating income before gains on asset dispositions was
primarily due to increased support of oil and gas activity and seasonal
flightseeing in Alaska. Additionally, operating income improved due to better
performance of the air medical group and hurricane related insurance recoveries.

ENVIRONMENTAL SERVICES - Operating income in the third quarter was $5.0 million
on operating revenues of $42.3 million compared to operating income of $3.0
million on operating revenues of $32.2 million in the preceding quarter.

The improvement in operating results was primarily due to increased response and
project management activity and consulting services.

DERIVATIVES - Derivative gains were $5.2 million in the third quarter compared
to losses of $0.3 million in the preceding quarter primarily as a result of
foreign currency forward contracts.

MARKETABLE SECURITIES - Marketable security gains were $12.0 million in the
third quarter compared to losses of $9.4 million in the preceding quarter.

EQUITY IN EARNINGS OF 50% OR LESS OWNED COMPANIES - Equity earnings from joint
ventures were $3.2 million in the third quarter compared to earnings of $7.8
million in the preceding quarter. In the preceding quarter, the Company sold its
Offshore Marine Services' joint venture in Egypt for a gain of $4.1 million, net
of tax.

CAPITAL COMMITMENTS - The Company's unfunded capital commitments as of September
30, 2007 consisted primarily of marine service vessels, harbor tugs,
helicopters, barges and capital improvements to certain of its existing marine
transportation fleet and totaled $527.5 million, of which $109.1 million is
payable during the remainder of 2007 and the balance payable through 2010. Of
these commitments, approximately $122.6 million may be terminated without
further liability other than the payment of liquidated damages of $10.1 million
in the aggregate. Subsequent to the end of the quarter, the Company committed to
purchase additional property and equipment for $6.2 million. As of September 30,
2007, the Company held balances of Cash, Cash Equivalents, Restricted Cash,
Securities, Construction Reserve Funds and Title XI Reserve Funds totaling
$876.5 million.
