          VERSUS  $1.67  EARNED  IN  THE  2003  YEAR

HOUSTON, TEXAS (OCTOBER 27, 2004) - Kirby Corporation ("Kirby") (NYSE:KEX) today
announced  net  earnings  for  the  third  quarter  ended  September 30, 2004 of
$13,250,000, or $.53 per share, an 18% improvement compared with $11,211,000, or
$.46  per  share,  for  the  third  quarter of 2003.  The 2004 third quarter net
earnings  were in line with Kirby's published earnings guidance range of $.50 to
$.54  per  share.  Consolidated  revenues  for  the  2004  third  quarter  were
$173,389,000,  a  12%  increase  compared  with  $154,507,000 for the 2003 third
quarter.

Kirby  reported  record  net  earnings  for  the  first  nine  months of 2004 of
$36,048,000,  or  $1.44  per share, a 21% increase compared with $29,868,000, or
$1.22  per  share, for the first nine months of 2003.  Consolidated revenues for
the  first  nine  months  of 2004 were $501,580,000, a 9% increase compared with
$461,446,000  for  the  first  nine  months  of  2003.

Marine  transportation  revenues and operating income for the 2004 third quarter
increased  14%  and  25%, respectively, compared with the third quarter of 2003.
For  the first nine months of 2004, marine transportation revenues and operating
income  increased  10%  and 20%, respectively, when compared with the first nine
months of 2003.  The favorable results reflected strong petrochemical volumes as
customers  continued  to  run  their  plants


                                  Page 1 of 7

at high utilization rates. Black oil volumes were strong, driven by high volumes of heavy refinery residual oil by-products, and refined products volumes reflected typical Midwest summer demand. Agricultural chemical volumes remained weak despite low Midwest inventory levels. The marine transportation 2004 third quarter and first nine months results were impacted by the following: - HURRICANE IVAN - Made landfall near Gulf Shores, Alabama on September 16 and resulted in customer petrochemical plant and refinery closures, diversion of marine equipment and closure of the Gulf Intracoastal Waterway along the projected path of the storm. The initial projected path was from New Orleans to the Florida panhandle. Hurricane Ivan impacted the inland marine operations, as well as the operations of the 35% owned offshore partnership with a Florida utility, lowering Kirby's results by an estimated $.02 per share. - DIESEL FUEL - The average price per gallon of diesel fuel consumed increased to $1.16 for the 2004 third quarter compared with $1.00 for the first six months of 2004. Higher fuel prices lowered Kirby's results by an estimated $.01 per share. - MCALPINE LOCK CLOSURE - Major lock on the Ohio River closed for repair for 12 days in August, stopping all waterborne traffic with a destination upriver of Louisville, Kentucky, including Cincinnati and Pittsburgh. The closure of the lock lowered Kirby's results by an estimated $.01 per share, less than initially forecasted. - SALE OF LIQUID PRODUCTS TERMINAL - Sale of the 50% owned Shreveport, La. terminal resulting in a third quarter 2004 loss on the sale of $.015 per share. This loss is reflected in equity in earnings of marine affiliates. The diesel engine services segment's third quarter 2004 revenues were in line with the 2003 third quarter revenues. Operating income improved by 7%, principally from increased sales of higher margin power generation parts. The segment's Midwest dry cargo river market was enhanced with the April 2004 purchase of the diesel engine services operations of Walker Paducah Corp. The segment's power generation market benefited from direct parts sales to a major power customer, while the rail market benefited from overall strong direct parts sales. The Gulf Coast offshore oil service market, and East Coast and West Coast marine markets remained weak, thereby negatively affecting the segment's 2004 third quarter results. Equity in earnings of marine affiliates for the 2004 third quarter was a loss of $782,000, and included the loss on the sale of the terminal and the negative impacts on the Company's 35% owned offshore partnership from Hurricanes Ivan, Frances and Jeanne. Joe Pyne, Kirby's President and Chief Executive Officer, commented, "Despite some challenges in the third quarter with respect to hurricanes, fuel, lock closures and the sale of the terminal, business levels allowed us to continue to perform well. Had it not been Page 2 of 7

for these challenges, we would have been comfortably above the high end of our forecasted range. We are forecasting net earnings for the 2004 fourth quarter in the $.50 to $.54 per share range. This guidance compares with net earnings of $.45 per share reported for the 2003 fourth quarter. Our 2004 fourth quarter guidance range is based on firm petrochemical and black oil volumes, normal winter upriver refined products volumes, stronger imported agricultural chemical volumes and increased delay days resulting from anticipated winter weather conditions." Mr. Pyne further commented, "For the 2004 year, Kirby's earnings per share guidance is $1.94 to $1.98. This guidance compares with 2003 year earnings per share of $1.67. Capital spending guidance for 2004 has been revised to $90 to $93 million from $85 to $90 million and includes approximately $42.5 million for the construction of 16 new 30,000 barrel petrochemical tank barges and 10 new 30,000 barrel black oil tank barges. The increased capital spending guidance reflects higher steel prices, progress payments on barges scheduled for delivery in 2005 and the timing of capital upgrades on existing equipment." This earnings press release includes marine transportation performance measures for both the 2004 and 2003 third quarters and first nine months. The performance measures include ton miles, revenues per ton mile, towboats operated and delay days. Comparable performance measures for the 2003 and 2002 years and quarters are available at Kirby's web site under the caption Performance Measurements in the Investor Relations section.

Kirby defines EBITDA as net earnings before interest expense, taxes on income, depreciation and amortization. EBITDA is presented because of its wide acceptance as a financial indicator. EBITDA is one of the performance measures used in Kirby's incentive bonus plan. EBITDA is also used by rating agencies in determining Kirby's credit rating and by analysts publishing research reports on Kirby, as well as by investors and investment bankers generally in valuing companies. EBITDA is not a calculation based on generally accepted accounting principles and should not be considered as an alternative to, but should only be considered in conjunction with, Kirby's GAAP financial information. (2) Ton miles indicate fleet productivity by measuring the distance (in miles) a loaded tank barge is moved. Example: A typical 30,000 barrel tank barge loaded with 3,300 tons of liquid cargo is moved 100 miles, thus generating 330,000 ton miles. (3) Marine transportation revenues divided by ton miles. Example: Third quarter 2004 revenues of $153,114,000 divided by 4,238,000,000 ton miles = 3.6 cents. (4) Towboats operated are the average number of owned and chartered towboats operated during the period. (5) Delay days measures the lost time incurred by a tow (towboat and tank barges) during transit. The measure includes transit delays caused by weather, lock congestion and other navigational factors. ### Page 7 of 7
