ACCOUNTING STANDARDS

In June 2006, Financial Accounting Standards Board (“FASB”) Interpretation No. 48, “Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109 (“FIN No. 48”) was issued. FIN No. 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s consolidated financial statements in accordance with Statement of Financial Accounting Standards No. 109, “Accounting for Income Taxes.” FIN No. 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The interpretation also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company is currently evaluating the impact of the interpretation on its consolidated financial statements, which the Company is required to adopt beginning in the first quarter of 2007.

In September 2006, the FASB issued FASB Staff Position No. AUG AIR-1, “Accounting for Planned Major Maintenance Activities.” This guidance prohibits the use of the accrue-in-advance method of accounting for planned major maintenance activities in interim and annual financial reporting periods because an obligation has not occurred and therefore a liability should not be recognized. The Company is currently evaluating the impact of the provisions of this guidance on its consolidated financials statements, which the Company is required to adopt beginning in the first quarter of 2007.

In September 2006, the FASB issued FASB No. 158, Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R) (“SFAS No. 158”). SFAS No. 158 requires an employer to: (a) recognize in its balance sheet an asset for a defined benefit plan’s overfunded status or a liability for its underfunded status; (b) recognize changes in the funded status of a defined benefit postretirement plan that are not recognized as components of net periodic benefit cost in comprehensive income in the year in which the changes occur; and (c) measure a plan’s assets and its obligations that determine its funded status as of the end of the employer’s fiscal year (with limited exceptions). The requirement to recognize the funded status of a benefit plan and the disclosure requirements are effective for the Company’s fiscal year ending on December 31, 2006. The requirement to measure plan assets and benefit obligations as of the date of a Company’s fiscal year end balance sheet is effective for the Company’s fiscal year ending on December 31, 2008. The Company is currently evaluating the impact of the provisions of this standard on its consolidated financial statements.

STOCK AWARD PLANS - (Continued)

Compensation cost capitalized as part of inventory is considered immaterial.

In December 2004, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards No. 123R, “Share-Based Payment” (“SFAS No. 123R”) which is a revision of Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation” (“SFAS No. 123”) and supersedes Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB No. 25”) and its related implementation guidance. SFAS No. 123R requires the Company to expense grants made under the stock option plans. The cost will be recognized over the vesting period of the options. SFAS No. 123R is effective for the first annual period beginning after December 15, 2005. Upon adoption of SFAS No. 123R, amounts previously disclosed under SFAS No. 123 will be recognized as expense in the consolidated statement of earnings. The Company adopted SFAS No. 123R effective January 1, 2006 using the modified prospective application. Accordingly, compensation expense will be recognized for all newly granted awards and awards modified, repurchased or cancelled after January 1, 2006. Compensation expense for the unvested portion of awards that were outstanding at January 1, 2006 will be recognized ratably over the remaining vesting period based on the fair value at date of grant as calculated under the Black-Scholes option pricing model.

Prior to 2006, the Company accounted for stock-based compensation utilizing the intrinsic value method in accordance with the provisions of APB No. 25. Under the intrinsic value method of accounting for stock-based employee compensation, since the exercise price of the Company’s stock options was at the fair market value on the date of grant, no compensation expense was recorded. The Company was required under SFAS No. 123 to disclose pro forma information relating to option grants as if the Company used the fair value method of accounting, which requires the recording of estimated compensation expenses.

Options granted on and after February 10, 2000 have terms of five years and vest ratably over three years. At September 30, 2006, 1,851,146 shares were available for future grants under the employee plans and no outstanding stock options under the employee plans were issued with stock appreciation rights.

The Company has three director stock award plans for nonemployee directors of the Company which provide for the issuance of stock options and restricted stock. No additional options can be granted under two of the plans. The third plan, the 2000 Director Plan, provides for the automatic grants of stock options and restricted stock to nonemployee directors on the date of first election as a director and after each annual meeting of stockholders. In addition, the 2000 Director Plan provides for the issuance of stock options or restricted stock in lieu of cash for all or part of the annual director fee. The exercise prices for all options granted under the plans are equal to the fair market value per share of the Company’s common stock on the date of grant. The terms of the options are 10 years. The options granted when first elected as a director vest immediately. The options granted and restricted stock issued after each annual meeting of stockholders vest six months after the date of grant. Options granted and restricted stock issued in lieu of cash director fees vest in equal quarterly increments during the year to which they relate. At September 30, 2006, 173,690 shares were available for future grants under the nonemployee director plans. The director stock award plans are intended as an incentive to attract and retain qualified and competent independent directors.

The following is a summary of the stock award activity under the director plans described above for the nine months ended September 30, 2006:

RETIREMENT PLANS

The Company sponsors a defined benefit plan for vessel personnel. The plan benefits are based on an employee’s years of service and compensation. The plan assets consists primarily of equity and fixed income securities.

The Company’s pension plan funding strategy is to contribute an amount equal to the greater of the minimum required contribution under ERISA or the amount necessary to fully fund the plan on an Accumulated Benefit Obligation (“ABO”) basis at the end of the fiscal year. The ABO is based on a variety of demographic and economic assumptions, and the pension plan assets’ returns are subject to various risks, including market and interest rate risk, making the prediction of the pension plan contribution difficult. Based on current pension plan assets and market conditions, the Company expects to contribute between $4,000,000 to $8,000,000 to its pension plan in November 2006 to fund its 2006 pension plan obligations. As of September 30, 2006, no 2006 year contributions have been made.

The Company sponsors an unfunded defined benefit health care plan that provides limited postretirement medical benefits to employees who meet minimum age and service requirements, and to eligible dependents. The plan is contributory, with retiree contributions adjusted annually.

CONTINGENCIES

The Company has issued guaranties or obtained stand-by letters of credit and performance bonds supporting performance by the Company and its subsidiaries of contractual or contingent legal obligations of the Company and its subsidiaries incurred in the ordinary course of business. The aggregate notional value of these instruments is $12,390,000 at September 30, 2006, including $11,470,000 in letters of credit and debt guarantees, and $920,000 in performance bonds, of which $683,000 relates to contingent legal obligations which are covered by the Company’s liability insurance program in the event the obligations are incurred. All of these instruments have an expiration date within five years. The Company does not believe demand for payment under these instruments is likely and expects no material cash outlays to occur in connection with these instruments.

In 2000, the Company and a group of approximately 45 other companies were notified that they are Potentially Responsible Parties (“PRPs”) under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) with respect to a Superfund site, the Palmer Barge Line Site (“Palmer”), located in Port Arthur, Texas. In prior years, Palmer had provided tank barge cleaning services to various subsidiaries of the Company. The Company and three other PRPs have entered into an agreement with the Environmental Protection Agency (“EPA”) to perform a remedial investigation and feasibility study. Based on information currently available, the Company believes its exposure is limited.

CONTINGENCIES - (Continued)

In 2004, the Company and certain subsidiaries received a Request For Information (“RFI”) from the EPA under CERCLA with respect to a Superfund site, the State Marine site, located in Port Arthur, Texas. An RFI is not a determination that a party is responsible or potentially responsible for contamination at a site, but is only a request seeking any information a party may have with respect to a site as part of an EPA investigation into such site. In July 2005, a subsidiary of the Company received a notification of potential responsibility from the EPA and a request for voluntary participation in funding potential remediation activities at the SBA Shipyards, Inc., (“SBA”) property located in Jennings, Louisiana. In prior years, SBA had provided tank barge cleaning services to the subsidiary. In July 2006, the Company received a RFI from the United States Department of Agriculture - Forest Service under CERCLA with respect to a former mine site in South Dakota. Based on information currently available, the Company is unable to ascertain the extent of its exposure, if any, in these matters.

In addition, the Company is involved in various legal and other proceedings which are incidental to the conduct of its business, none of which in the opinion of management will have a material effect on the Company’s financial condition, results of operations or cash flows. Management believes that it has recorded adequate reserves and believes that it has adequate insurance coverage or has meritorious defenses for these other claims and contingencies.

Overview

The Company is the nation’s largest domestic inland tank barge operator with a fleet of 903 active tank barges as of September 30, 2006 and operated an average of 242 towing vessels during the 2006 third quarter and 241 during the 2006 first nine months. The Company uses the inland waterway system of the United States to transport bulk liquids including petrochemicals, black oil products, refined petroleum products and agricultural chemicals. The Company also owns and operates four ocean-going barge and tug units transporting dry-bulk commodities in United States coastwise trade. Through its diesel engine services segment, the Company provides after-market services for large medium-speed and high-speed diesel engines and reduction gears used in marine, power generation and railroad applications.

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Overview - (Continued)

For the 2006 third quarter, the Company reported net earnings of $25,600,000, or $.48 per share, on revenues of $264,612,000, a significant improvement over 2005 third quarter net earnings of $17,285,000, or $.34 per share, on revenues of $198,741,000. For the first nine months of 2006, the Company reported net earnings of $71,513,000, or $1.34 per share, on revenues of $732,807,000, compared with 2005 first nine months net earnings of $49,011,000, or $.95 per share, on revenues of $582,461,000. The 2006 third quarter and first nine months performance reflected continued strong petrochemical and black oil products demand in the marine transportation segment, coupled with higher contract rate renewals and higher spot market pricing. The diesel engine services segment also performed at strong levels in the 2006 third quarter and first nine months, the result of continued strong service and parts sales across the majority of its markets, higher service rates and parts pricing, and accretive earnings from the Global and MES acquisitions.

Marine Transportation

For the 2006 third quarter and first nine months, approximately 80% and 82%, respectively, of the Company’s revenue was generated by its marine transportation segment. The segment’s inland customers include many of the major petrochemical and refining companies in the United States. Products transported include raw materials for many of the end products used widely by businesses and consumers every day - plastics, fiber, paints, detergents, oil additives and paper, among others. Consequently, the Company’s business tends to mirror the general performance of the United States economy and the performance of the Company’s customer base. The following table shows the markets serviced by the Company, the revenue distribution for the first nine months of 2006, products moved and the drivers of the demand for the products the Company transports:

Markets Serviced	2006 First Nine Months Revenue Distribution	Products Moved	Drivers
Petrochemicals	67%	Benzene, Styrene, Methanol, Acrylonitrile, Xylene, Caustic Soda, Butadiene, Propylene	Housing, Consumer Goods, Clothing, Automobiles

Black Oil Products	20%	Residual Fuel, No. 6 Fuel Oil, Coker Feedstocks, Vacuum Gas, Asphalt, Boiler Fuel, Crude Oil, Ship Bunkers	Road Construction, Refinery Utilization, Fuel for Power Plants and Ships

Refined Petroleum Products	10%	Gasoline Blends, No. 2 Oil, Jet Fuel, Heating Oil	Vehicle Usage, Air Travel, Weather Conditions, Refinery Utilization

Agricultural Chemicals	3%	Anhydrous Ammonia, Nitrogen Based Liquid Fertilizer, Industrial Ammonia	Agricultural Economy, Chemical Feedstock Usage

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Overview - (Continued)

The Company’s marine transportation segment’s revenue and operating income for the 2006 third quarter increased 23% and 42%, respectively, when compared with the third quarter of 2005. For the 2006 first nine months, revenue and operating income increased 21% and 37%, respectively, compared with the first nine months of 2005. The petrochemical market is the Company’s largest market, contributing 67% of the marine transportation revenue for the 2006 first nine months. During the third quarter and first nine months, the demand for the movement of petrochemicals remained strong, with term contract customers continuing to operate their plants and facilities at high utilization rates, resulting in high tank barge utilization. The black oil products market contributed 20% of 2006 first nine months marine transportation revenue. This market also remained strong as refineries continued to operate at close to full capacity, generating high demand for the transportation of heavier residual oil by-products. Refined petroleum products contributed 10% of 2006 first nine months marine transportation revenue, experiencing higher than normal demand for the movement of products from the Gulf Coast to the Midwest. The agricultural chemical market, which contributed 3% of 2006 first nine months marine transportation revenue, was weak due primarily to high inventory levels in the Midwest.

The 2006 third quarter and first nine months results were negatively impacted by a continued shortage of vessel personnel and a shortage of Gulf Coast towboats, both created by Hurricanes Katrina and Rita in the 2005 third quarter. The vessel personnel shortage resulted in higher vessel personnel wages and higher training costs as a result of increased training of vessel personnel at all levels. The shortage of Gulf Coast charter towboats resulted in the payment of higher charter rates to attract and retain the boats.

The 2006 first quarter was positively impacted by an estimated $.03 to $.04 per share from diesel fuel cost recovery clauses in certain marine transportation long-term contracts. The 2006 second quarter earnings were negatively impacted by an estimated $.03 to $.04 per share from fuel cost recovery under the same long-term contracts. For the 2006 third quarter and the first nine months of 2006, the estimated impact of the diesel fuel cost recovery clauses was neutral.

During the 2006 third quarter and first nine months, approximately 70% of the marine transportation revenues were under term contracts and 30% were spot market revenues. Rates under term contracts renewed during the 2006 third quarter and first nine months increased in the 4% to 8% average range, with some contracts increasing by a higher percentage and some by a lower percentage. Effective January 1, 2006, annual escalators for labor and the producer price index on a number of multi-year contracts resulted in rate increases for those contracts by 2.5% to 3%. Spot market rates for the 2006 third quarter and first nine months for most marine transportation markets increased over 25% compared with the 2005 corresponding periods. The Company adjusts term contract rates for fuel on either a monthly or quarterly basis, depending on the specific contract. Spot market rates include the cost of fuel. During the 2006 third quarter, the average cost of fuel consumed was $2.08 per gallon, 19% higher than the $1.75 per gallon average cost of fuel consumed during the 2005 third quarter. During the 2006 first nine months, the average cost of fuel consumed was $1.97 per gallon, 27% higher than the $1.55 per gallon for the 2005 first nine months.

Navigational delay days for the 2006 third quarter were 1,200, down 42% compared with 2,080 delay days recorded in the 2005 third quarter. For the 2006 first nine months, navigational delay days were 5,049, down 29% compared with 7,159 delay days recorded in the 2005 first nine months. The reduction for both 2006 periods was primarily the result of favorable weather conditions and water levels during the 2006 first nine months compared with high water conditions on the Illinois, Ohio and Mississippi Rivers in the 2005 first quarter, and delays caused by Hurricanes Katrina and Rita in the 2005 third quarter.

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Overview - (Continued)

The marine transportation operating margins for the 2006 third quarter and first nine months improved to 19.4% and 18.8%, respectively, when compared with 16.7% for the 2005 third quarter and first nine months. Continued strong demand, contract and spot market rate increases, the January 1, 2006 escalators on long-term contracts and favorable weather conditions, partially offset by towboat shortages and vessel personnel wage increases, contributed to the higher 2006 operating margins for both comparable periods.

Diesel Engine Services

For the 2006 third quarter and first nine months, approximately 20% and 18%, respectively, of the Company’s revenue was generated by its diesel engine services segment of which 64% and 62% was generated through service and 36% and 38% from parts sales, respectively. The results of the diesel engine services segment are largely influenced by the economic cycles of the industries it serves. The following table shows the markets serviced by the Company, the revenue distribution for the first nine months of 2006 and the customers for each market:

Markets Serviced	2006 First Nine Months Revenue Distribution	Customers
Marine	70%	Inland River Carriers - Dry and Liquid, Offshore Towing - Dry and Liquid, Offshore Oilfield Services - Drilling Rigs & Supply Boats, Harbor Towing, Dredging, Great Lake OreCarriers

Power Generation	17%	Standby Power Generation, Pumping Stations

Railroad	13%	Passenger (Transit Systems), Class II Shortline, Industrial

The Company’s diesel engine services segment’s 2006 third quarter revenue and operating income increased 102% and 154%, respectively, compared with the third quarter of 2005. For the first nine months of 2006, revenue and operating income increased 56% and 96%, respectively, compared with the first nine months of 2005. The results were positively impacted by the accretive acquisitions of Global and MES, as well as from continued strong in-house and in-field service activity and direct parts sales in the majority of its markets, and from higher service rates and parts pricing implemented during 2005 and during the 2006 third quarter and first nine months.

The diesel engine services segment’s operating margins for the 2006 third quarter improved to 15.3% compared with 12.2% for the third quarter of 2005. For the first nine months of 2006, the operating margin was 15.5% compared with 12.3% for the first nine months of 2005. The higher margins resulted from the accretive Global and MES acquisitions, strong markets, higher service activities, which generally earn a higher operating margin than parts sales, increased pricing for service and parts, and higher labor utilization.

The Company continued to generate strong operating cash flow during the 2006 first nine months, with net cash provided from operations of $103,201,000. Net cash provided from operations for the 2005 first nine months was $105,977,000. In addition, during the 2006 and 2005 first nine months, the Company generated cash of $12,108,000 and $5,338,000, respectively, from the exercise of stock options. The cash, and borrowings under the Company’s Revolving Credit Facility, were used for capital expenditures of $110,114,000, primarily for fleet replacement, enhancement and expansion, and $139,425,000 for the acquisition of the remaining 65% interest in Dixie Fuels, the acquisitions of Global, MES and Gulf Coast Fire & Safety, and the purchase of 16 towboats, including eight from Capital Towing. The Company’s debt-to-capitalization ratio increased from 27.1% at December 31, 2005 to 34.3% at September 30, 2006 primarily due to borrowings under the Company’s Revolving Credit Facility to finance the acquisitions noted above.

Capital expenditures for the 2006 first nine months were $110,114,000 and included $44,253,000 for new tank barge and towboat construction and $65,861,000 primarily for upgrading the existing marine transportation fleet.

The Company projects that capital expenditures for 2006 will be in the $138,000,000 to $143,000,000 range, including approximately $60,000,000 for new tank barge and towboat construction, with the remainder primarily for upgrading the existing marine transportation fleet. During 2005 and 2006, the Company entered into contracts for the construction of twenty-three 30,000 barrel tank barges at a cost of $45,000,000, subject to adjustment for the price of steel, and two 10,000 barrel specialty tank barges for use in the petrochemical market at a cost of approximately $2,300,000, subject to adjustment for the price of steel. Fifteen of the 30,000 barrel tank barges will be additional capacity and eight will be replacement barges for older barges removed from service. The two 10,000 barrel tank barges will be additional capacity. Delivery of the twenty-three 30,000 barrel barges will be throughout 2006, with the final four barges scheduled for delivery in the 2007 first half. One of the 10,000 barrel barges is scheduled for delivery in December 2006 and one in the 2007 first quarter. During 2005, the Company also entered into a contract for the construction of four 2100 horsepower inland towboats at a cost of approximately $13,000,000, $3,200,000 of which was paid in December 2005 and included in the 2005 capital expenditures. One towboat is scheduled to be placed into service in the fourth quarter of 2006 and three in the 2007 first half.

In March 2006, the Company entered into a contract for the construction of twelve 30,000 barrel tank barges at a cost of approximately $28,000,000, subject to adjustment for the price of steel. In April 2006, the Company entered into a contract for the construction of eight 30,000 barrel tank barges at a cost of approximately $15,000,000, subject to adjustment for the price of steel. Of the 20 new 30,000 barrel tank barges under contract, 14 barges will be additional capacity and 6 barges will be replacement barges for older barges removed from service. Delivery of 18 of the 20 new 30,000 barrel tank barges is scheduled throughout 2007 with the remaining two in the 2008 first half. In August 2006, the Company entered into a contract for the construction of four 1800 horsepower inland towboats at a cost of approximately $13,000,000, subject to adjustment for the price of steel.

Overview - (Continued)

The Company remains in excellent financial position to take advantage of internal and external growth opportunities in its marine transportation and diesel engine services segments. For the marine transportation segment, external growth opportunities include potential acquisitions of independent inland tank barge operators and fleet owners seeking to single source tank barge requirements. Increasing the fleet size will allow the Company to improve asset utilization through more backhaul opportunities, faster barge turnarounds, more efficient use of towboats, barges positioned closer to cargos, lower incremental costs due to enhanced purchasing power, minimal incremental administrative staff and less cleaning due to operating more barges with compatible prior cargos. In addition to the Global and MES acquisitions, the diesel engine services segment’s external growth opportunities include further consolidation of strategically located diesel service providers, and expanded service capability for other engine and marine gear related products.

For the remainder of 2006, the Company anticipates continued strong petrochemical, black oil and refined products volumes for its marine transportation segment. For its diesel engine services segment, the Company anticipates continued strong service activity and parts sales.

Marine Transportation

The Company, through its marine transportation segment, is a provider of marine transportation services, operating inland tank barges and towing vessels, transporting petrochemicals, black oil products, refined petroleum products and agricultural chemicals along the United States inland waterways. As of September 30, 2006, the Company operated 903 active inland tank barges, with a total capacity of 17.0 million barrels, compared with 889 active inland tank barges at September 30, 2005, with a total capacity of 16.6 million barrels. The Company operated an average of 242 active inland towing vessels during the 2006 third quarter and 241 during the first nine months compared with an average of 243 during the 2005 third quarter and 242 during the first nine months of 2005. The Company also owns and operates four dry-bulk barge and tug units.

The following table sets forth the Company’s marine transportation segment’s revenues, costs and expenses, operating income and operating margins for the three months and nine months ended September 30, 2006 compared with the three months and nine months ended September 30, 2005 (dollars in thousands):

	Three months ended September 30,									Nine months ended September 30,

Marine Transportation Revenues

Marine transportation revenues for the 2006 third quarter and first nine months increased 23% and 21%, respectively, compared with the corresponding 2005 periods, reflecting continued strong petrochemical, black oil products and refined petroleum products demand, as well as favorable 2006 third quarter and first nine months weather conditions. In addition, the segment benefited from 2005 year and 2006 first nine months contract and spot market rate increases, and annual labor and producer price index escalators during 2006 on a number of multi-year contracts. The 2005 third quarter and first nine months revenues were negatively impacted by Hurricanes Katrina and Rita and the Company estimated that the two back to back Gulf Coast hurricanes negatively impacted the 2005 third quarter and first nine months by $.05 per share.

Marine Transportation Revenues - (Continued)

Petrochemical transportation demand for the 2006 third quarter and first nine months remained strong, benefiting from a continued strong United States economy. Term customers continued to operate their plants and facilities at high utilization rates, resulting in continued high barge utilization for most products and trade lanes.

Black oil products demand during the 2006 third quarter and first nine months remained strong as refineries operated at close to full capacity, which generated heavy demand for waterborne transportation of heavier refinery residual oil by-products.

Refined petroleum products demand for transportation into the Midwest during the 2006 third quarter and first nine months was stronger than normal. During the first half of 2006, barge availability for movements of refined products into the Midwest was constrained due to the diversion of barges to the stronger Gulf Intracoastal Waterway petrochemical market to meet term contract requirements and the Company’s continued retirement of single hull barges. During the 2006 third quarter, because of the towboat shortage in the Gulf Intracoastal Waterway, certain tank barges were diverted back to the Mississippi River to meet strong demand for refined products movements into the Midwest.

Agricultural chemical demand was weak during the 2006 third quarter and first nine months, primarily due to high Midwest liquid fertilizer inventory levels which reduced demand for movements of imported liquid fertilizer into the Midwest.

As described under Acquisitions above, the Company acquired an additional one-third interest in Osprey in January 2006, increasing the Company’s ownership to 67%, and purchased in March 2006 the remaining 65% of the Dixie Fuels partnership, bringing the Company’s ownership to 100%. As a result of the acquisitions, the Company began consolidating the results of both entities in the marine transportation segment beginning on their acquisition dates. During the 2006 third quarter and first nine months, the entities contributed a combined $10,583,000 and $25,862,000, respectively, of marine transportation revenues.

For the third quarter of 2006, the marine transportation segment incurred 1,200 delay days, a 42% improvement over the 2005 third quarter delay days of 2,080. For the 2006 first nine months, 5,049 delay days occurred, 29% lower than the 7,159 delay days incurred in the 2005 first nine months. The lower 2006 delay days primarily reflected unusually favorable 2006 first quarter winter weather conditions and water levels, a slight improvement in 2006 second quarter weather conditions and water levels, and a significant improvement in the 2006 third quarter weather conditions when compared with the 2005 third quarter, which was negatively impacted by Hurricanes Katrina and Rita.

During the 2006 third quarter and first nine months, approximately 70% of marine transportation revenues were under term contracts and 30% were spot market revenues. The 70% contract and 30% spot market mix provides the Company with a stable revenue stream with less exposure to day-to-day pricing fluctuations. Rates under term contracts renewed in the 2006 third quarter and first nine months increased in the 4% to 8% average range, primarily the result of continued strong industry demand and high utilization of tank barges. Spot market rates for the 2006 third quarter and first nine months, including fuel, increased over 25% compared with the 2005 third quarter and first nine months. Effective January 1, 2006, escalators for labor and the producer price index on a number of multi-year contracts increased rates on such contracts by 2.5% to 3%.

Marine Transportation Revenues - (Continued)

Hurricanes Katrina and Rita negatively impacted the 2005 third quarter and first nine months. Hurricane Katrina made landfall east of New Orleans on August 29 and Hurricane Rita made landfall on the Texas - Louisiana border on September 24. Petrochemical and refinery facilities located in the paths or projected paths of the hurricanes shutdown operations in advance of the storms. Waterways in the hurricane affected areas were closed and Kirby’s equipment was moved out of the path of the storms. The hurricanes caused no notable damage to Kirby’s tank barge and towboat fleet or its facilities. The impact of the hurricanes was mitigated to some degree by risk sharing provisions in many of the segment’s contracts, enabling the Company to recover some of the costs related to navigational delays beyond the Company’s control. In addition, some customers opted to place equipment on a time charter basis prior to the hurricanes, and remained on charter through the storms.

Marine Transportation Costs and Expenses

Costs and expenses for the 2006 third quarter and first nine months increased 19% and 18%, respectively, compared with the 2005 third quarter and first nine months, reflecting the higher costs and expenses associated with increased marine transportation demand noted above. The increase also reflected the consolidation of Dixie Fuels effective March 1, 2006 and Osprey effective January 1, 2006.

Costs of sales and operating expenses for the 2006 third quarter and first nine months increased 20% compared with the corresponding 2005 periods, reflecting increased operation and vessel personnel salaries and related expenses, additional expenses associated with the increased demand and higher towboat and tank barge maintenance expenditures. Both 2006 periods reflected higher vessel personnel wages and higher rates for chartered towboats, the direct result of Hurricanes Katrina and Rita, which tightened the Gulf Coast labor pool and towboat market. The tight vessel labor market resulted in higher training costs as a result of increased training of vessel personnel at all levels. In addition, the higher price of diesel fuel consumed, resulted in higher fuel costs. During the 2006 third quarter, the Company operated an average of 242 towboats compared with an average of 243 during the 2005 third quarter. For the first nine months of 2006, the segment operated 241 towboats compared with 242 for the 2005 first nine months. During the 2006 third quarter, the Company consumed 13.6 million gallons of diesel fuel, slightly less than the 13.9 million consumed in the 2005 third quarter. For the 2006 first nine months, the segment consumed 40.4 million gallons of diesel fuel, slightly less than the 41.0 million gallons consumed during the 2005 first nine months.

The average price per gallon of diesel fuel consumed during the 2006 third quarter was $2.08 compared with $1.75 per gallon for the third quarter of 2005 and $1.97 per gallon for the 2006 first nine months compared with $1.55 per gallon for the 2005 first nine months. Term contracts contain fuel escalation clauses that allow the Company to recover increases in the cost of fuel; however, there is generally a 30 to 90 day delay before the contracts are adjusted. Spot market rates include the cost of fuel.

Selling, general and administrative expenses for the 2006 third quarter and first nine months increased 14% and 11%, respectively, compared with the corresponding 2005 periods. The increase primarily reflected January 1, 2006 salary increases and related expenses, the impact of expensing stock options effective January 1, 2006 in accordance with SFAS No. 123R and the consolidation of Dixie Fuels and Osprey in 2006.

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Marine Transportation Costs and Expenses - (Continued)

Taxes, other than on income, decreased 2% for the 2006 third quarter and increased 3% for the first nine months compared with the corresponding periods of 2005, as the 2005 periods reflected lower taxes as a result of a favorable settlement of a multiple year property tax issue.

Depreciation and amortization for the 2006 third quarter increased 19% compared with the 2005 third quarter and increased 10% for the 2006 first nine months compared with the 2005 first nine months. The increase for both 2006 periods was primarily attributable to increased capital expenditures, including new tank barges, as well as increased depreciation and amortization from the consolidation of Dixie Fuels effective March 2006.

Marine Transportation Operating Income and Operating Margins

The marine transportation operating income for the 2006 third quarter increased 42% compared with the 2005 third quarter. For the 2006 first nine months, the operating income for the segment increased 37% compared with the first nine months of 2005. The operating margin for the 2006 third quarter increased to 19.4% compared with 16.7% for the third quarter of 2005 and 18.8% for the 2006 first nine months compared with 16.7% for the 2005 first nine months. Continued strong demand, favorable 2006 third quarter and first nine months weather conditions, higher contract and spot market pricing and the January 1, 2006 escalators on a number of multi-year contracts, partially offset by towboat shortages and vessel personnel wage increases, positively impacted the 2006 operating income and operating margins for both comparable periods.

Diesel Engine Services

The Company, through its diesel engine services segment, sells genuine replacement parts, provides service mechanics to overhaul and repair large medium-speed and high-speed diesel engines and reduction gears, and maintains facilities to rebuild component parts or entire large medium-speed and high-speed diesel engines, and entire reduction gears. The segment services the marine, power generation and railroad markets.

Diesel Engine Services Revenues

Diesel engine services revenues for the 2006 third quarter increased 102% compared with the 2005 third quarter and 56% for the first nine months of 2006 compared with the 2005 first nine months. During both 2006 periods, the segment was positively impacted by the acquisitions of Global and MES, both high-speed Gulf Coast service providers, which were purchased on June 7, 2006 and July 21, 2006, respectively. In addition, the segment benefited from increased service modification projects and parts sales in its marine, offshore oil service, power generation and railroad markets, emission compliance projects for Gulf Coast and West Coast customers, and better labor utilization. The Company also benefited from higher service rates and parts pricing during 2005 and in the 2006 first nine months.

Diesel Engine Services Costs and Expenses

Costs and expenses for the 2006 third quarter and first nine months increased 95% and 50%, respectively, when compared with corresponding periods of 2005. The significant increase in each cost and expense category was primarily attributable to the Global and MES acquisitions. In addition, increases in costs of sales and operating expenses reflected the higher service and parts sales activity noted above, as well as increases in salaries and other related benefit expenses effective January 1, 2006. Selling, general and administrative expenses also reflected a January 1, 2006 increase in salaries and related expenses, and the expensing of stock options effective January 1, 2006.

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Diesel Engine Services Operating Income and Operating Margins

Operating income for the diesel engine services segment for the 2006 third quarter and first nine months increased 154% and 96%, respectively, compared with the corresponding periods of 2005. The significant increase in both 2006 periods reflected the accretive earnings from the Global and MES acquisitions, stronger markets noted above, increased service and parts pricing, and higher service revenue versus parts revenue mix. During the 2006 third quarter and first nine months, 64% and 62%, respectively, of the segment’s revenue was from service versus 60% and 58%, respectively, for the corresponding periods of 2005. The higher operating margins, 15.3% for the 2006 third quarter and 15.5% for the 2006 first nine months versus 12.2% for the 2005 third quarter and 12.3% for the 2005 first nine months, was primarily a reflection of the Global and MES acquisitions, higher margin service revenue mix, increased pricing for service and parts and higher labor utilization.

General Corporate Expenses

General corporate expenses for the 2006 third quarter were $3,199,000, or 58% higher than the third quarter of 2005. For the first nine months of 2006, general corporate expenses were $9,030,000, a 45% increase compared with the 2005 first nine months. The increase for both comparable periods reflected increases in salaries and related expenses effective January 1, 2006, higher employee incentive compensation accruals, higher legal fees and the expensing of stock options effective January 1, 2006. The increase for the 2006 first nine months also included stock listing fees associated with the two-for-one stock split.

Gain on Disposition of Assets

The Company reported a net gain on disposition of assets of $255,000 and $1,197,000 for the 2006 third quarter and first nine months, respectively, compared with a loss on disposition of assets of $24,000 and a gain of $1,963,000 for the corresponding periods of 2005, respectively. The disposition of assets for all reported periods was predominantly from the sale of inland tank barges and towboats.

With the early extinguishment, the Company expensed $1,144,000 of unamortized financing costs associated with the retired 2003 Senior Notes during the 2005 second quarter.

Interest expense for the 2006 third quarter increased 50% compared with the 2005 third quarter, primarily the result of additional borrowings under the Company’s Revolving Credit Facility to fund the 2006 acquisition of Global. For the 2006 first nine months, interest expense increased 13% compared with the 2005 first nine months, primarily the result of higher average debt due to the Global acquisition, partially offset by a favorable first quarter 2006 interest adjustment associated with the final settlement of the audit of the Company’s 2002 through 2004 federal tax returns with the Internal Revenue Service. The average debt and average interest rate for the third quarter of 2006 and 2005, including the effect of interest rate swaps, were $300,929,000 and 6.0%, and $211,898,000 and 5.6%, respectively. For the first nine months of 2006 and 2005, the average debt and average interest rate, including the effect of interest rate swaps and excluding the Internal Revenue Service interest expense, were $240,827,000 and 6.0%, and $210,761,000 and 5.9%, respectively.

Financial Condition, Capital Resources and Liquidity

Balance Sheet

Total assets as of September 30, 2006 were $1,269,222,000 compared with $1,025,548,000 as of December 31, 2005. The 24% increase primarily reflected the acquisitions of Global in June 2006, MES in July 2006 and eight towboats from Capital in August 2006, and the consolidation of Dixie Fuels and Osprey beginning in the 2006 first quarter.

Current assets as of September 30, 2006 increased 34% compared with December 31, 2005, primarily reflecting the current assets of Global, Dixie Fuels and Osprey. The 77% decrease in cash and cash equivalents reflected the use of existing cash for the Global acquisition. In addition to the acquisitions, the 35% increase in trade accounts receivable reflected the increase in both marine transportation and diesel engine services revenues. Other accounts receivable increased 107%, primarily reflecting $7,000,000 escrowed in the Global acquisition to secure the obligations of the sellers of Global under the purchase agreement. This escrow account receivable is offset by a $7,000,000 escrow account recorded in accrued liabilities. The 113% increase in inventory - finished goods for the diesel engine services segment reflected the inventory acquired with the Global and MES acquisitions, as well as higher inventory levels in support of stronger service activity and parts sales during the 2006 first nine months, as well as service projects to be delivered in the 2006 fourth quarter.

Property and equipment, net of accumulated depreciation, at September 30, 2006 increased 17% compared with December 31, 2005. The increase reflected $110,114,000 of capital expenditures for the 2006 first nine months, more fully described under Capital Expenditures below, the fair value of the property and equipment acquired in the Global, MES, Dixie Fuels, Gulf Coast Fire & Safety and Osprey transactions of $26,904,000, and the purchase of 16 towboats, including the eight purchased from Capital, for $18,074,000, less $45,320,000 of depreciation expense and $2,830,000 of property disposals during the 2006 first nine months.

Investment in marine affiliates as of September 30, 2006 decreased 81% compared with December 31, 2005, primarily reflecting the consolidation of the Dixie Fuels and Osprey equity investments which were previously recorded under the equity method of accounting prior to their acquisition by the Company in the 2006 first quarter.

Goodwill - net as of September 30, 2006 increased 39% compared with December 31, 2005, reflecting the goodwill recorded in the Global and MES acquisitions, and the January 2006 acquisition of an additional 33% interest in Osprey, bringing the Company’s ownership to 67%. Osprey was previously recorded under the equity method of accounting.

Other assets as of September 30, 2006 increased 87% compared with December 31, 2005. The increase was primarily attributable to an increase in intangibles related to the value assigned to non-compete agreements, dealerships and customer relationships in the Global, MES and Gulf Coast Fire & Safety acquisitions, the value assigned to the PFC marine transportation contract in the Dixie Fuels acquisition and its subsequent amendment in August 2006, long-term notes receivable from the sale of two towboats, an increase in the fair value of interest rate swaps and the repurchase of a diesel engine distribution agreement. The increases were partially offset by the amortization of the long-term pension asset and the amortization of intangibles.

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Balance Sheet - (Continued)

Current liabilities as of September 30, 2006 increased 12% compared with December 31, 2005, reflecting the current liabilities of Global, Dixie Fuels and Osprey. Accounts payable increased 15%, attributable to higher marine transportation and diesel engine services business levels and higher shipyard maintenance accruals. Accrued liabilities increased 13% primarily due to the Global acquisition and higher casualty loss accruals, partially offset by the 2006 payment of employee incentive compensation accrued during 2005. The increase due to the Global acquisition was principally due to a $7,000,000 escrow account liability expected to be settled in the next twelve months. This escrow account liability is offset by a $7,000,000 escrow account recorded in other receivables as discussed above.

Deferred income taxes as of September 30, 2006 increased 8% compared with December 31, 2005, primarily reflecting the recording of $11,888,000 of state and federal deferred taxes associated with the Global acquisition. The deferred state and federal tax liability was recorded to reflect the tax effect of the difference in the financial basis of the assets over the tax basis.

Minority interest and other long-term liabilities as of September 30, 2006 increased 4% compared with December 31, 2005, primarily due to an increase in lease reserves as a result of a buildout allowance given on a new lease on the Company’s corporate headquarters and the recording of a $1,271,000 decrease in the fair value of swap agreements, more fully described under Long-Term Financing below.

Stockholders’ equity as of September 30, 2006 increased 17% compared with December 31, 2005. The increase was the result of $71,513,000 of net earnings for the first nine months of 2006, a $7,265,000 decrease in treasury stock, an increase of $2,643,000 in common stock due to the stock split, an increase of $2,420,000 in additional paid-in capital, a $786,000 increase in accumulated other comprehensive income and an increase of $5,060,000 in unearned compensation. The decrease in treasury stock was attributable to the exercise of stock options and the issuance of restricted stock, partially offset by the purchase during the 2006 third quarter of $4,789,000 of Company common stock, more fully described under Treasury Stock Purchases below. The increase in accumulated other comprehensive income resulted from the net changes in fair value of interest rate swap agreements, net of taxes, more fully described under Long-Term Financing below. As a result of the adoption of SFAS No. 123R, the balance of $5,060,000 in unearned compensation as of January 1, 2006 was reclassified to and reduced the balance of additional paid-in capital.

Long-Term Financing

The Company has an unsecured Revolving Credit Facility with a syndicate of banks with JP Morgan Chase Bank as the agent bank. On June 14, 2006, the Company increased the Revolving Credit Facility from $150,000,000 to $250,000,000 and extended the maturity date to June 14, 2011 from the previous maturity date of December 9, 2007. The Revolving Credit Facility allows for an increase in the commitments of the banks from $250,000,000 up to a maximum of $325,000,000, subject to the consent of each bank that elects to participate in the increased commitment. The unsecured Revolving Credit Facility has a variable interest rate spread based on LIBOR that varies with the Company’s senior debt rating and the level of debt outstanding. As of September 30, 2006, the Company had $123,900,000 of borrowings outstanding under the Revolving Credit Facility. The Revolving Credit Facility includes a $25,000,000 commitment which may be used for standby letters of credit of which $7,612,000 was outstanding as of September 30, 2006. The Company was in compliance with all Revolving Credit Facility covenants as of September 30, 2006.

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Long-Term Financing - (Continued)

On May 31, 2005, the Company issued $200,000,000 of unsecured floating rate senior notes (“2005 Senior Notes”) due February 28, 2013. The 2005 Senior Notes pay interest quarterly at a rate equal to LIBOR plus a margin of 0.5%. The 2005 Senior Notes are callable, at the Company’s option, with a 1% prepayment premium until May 31, 2007 and at par thereafter. No principal payments are required until maturity in February 2013. The proceeds of the 2005 Senior Notes were used to repay the outstanding balance of the Company’s $200,000,000 unsecured floating rate senior notes due February 2013 with an interest rate equal to LIBOR plus a margin of 1.2%. With the early extinguishment, the Company expensed $1,144,000 of unamortized financing costs associated with the retired senior notes during the 2005 second quarter. As of September 30, 2006, $200,000,000 was outstanding under the 2005 Senior Notes and the Company was in compliance with all 2005 Senior Notes covenants.

The Company has a $5,000,000 line of credit (“Credit Line”) with Bank of America, N.A. (“Bank of America”) for short-term liquidity needs and letters of credit. The Credit Line was reduced from $10,000,000 to $5,000,000 in June 2006, with a maturity date of June 30, 2007. The Credit Line allows the Company to borrow at an interest rate agreed to by Bank of America and the Company at the time each borrowing is made or continued. The Company did not have any borrowings outstanding under the Credit Line as of September 30, 2006. Outstanding letters of credit under the Credit Line were $604,000 as of September 30, 2006.

The Company has on file with the Securities and Exchange Commission a shelf registration for the issuance of up to $250,000,000 of debt securities, including medium term notes, providing for the issuance of fixed rate or floating rate debt with a maturity of nine months or longer. As of September 30, 2006, $121,000,000 was available under the shelf registration, subject to mutual agreement to terms, to provide financing for future business or equipment acquisitions, working capital requirements and reductions of the Company’s Revolving Credit Facility and 2005 Senior Notes. As of September 30, 2006, there were no outstanding debt securities under the shelf registration.

From time to time, the Company hedges its exposure to fluctuations in short-term interest rates under its variable rate bank credit facility and floating rate senior notes by entering into interest rate swap agreements. The interest rate swap agreements are designated as cash flow hedges, therefore, the changes in fair value, to the extent that the swap agreements are effective, are recognized in other comprehensive income until the hedged interest expense is recognized in earnings. As of September 30, 2006, the Company had a total notional amount of $150,000,000 of interest rate swaps designated as cash flow hedges for its variable rate senior notes as follows (dollars in thousands):

Notional amount		Effective date	Termination date	Fixed pay rate	Receive rate
$	100,000	March 2006	February 2013	5.45%	Three-month LIBOR
$	50,000	April 2004	May 2009	4.00%	Three-month LIBOR

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Long-Term Financing - (Continued)

These interest rate swaps hedge a majority of the Company’s long-term debt and only an immaterial loss on ineffectiveness was recognized in the 2006 first nine months. At September 30, 2006, the fair value of the interest rate swap agreements was $1,231,000 of which $1,240,000 and $2,471,000 was recorded as other assets and other long-term liabilities, respectively. The Company has recorded in interest expense, net losses (gains) related to the interest rate swap agreements of $(122,000) and $619,000 for the three months ended September 30, 2006 and 2005, respectively, and $81,000 and $2,366,000 for the nine months ended September 30, 2006 and 2005, respectively. The Company anticipates $364,000 of net gains included in accumulated other comprehensive income will be transferred into earnings over the next year based on current interest rates. Gains or losses on the interest rate swap contracts offset increases or decreases in rates of the underlying debt, which results in a fixed rate for the underlying debt. Fair value amounts were determined as of September 30, 2006 and 2005 based on quoted market values of the Company’s portfolio of derivative instruments.

Capital Expenditures

Capital expenditures for the 2006 first nine months were $110,114,000, of which $44,253,000 was for construction of new tank barges and towboats, and $65,861,000 was primarily for upgrading of the existing marine transportation fleet. Financing of the construction of the new tank barges and towboats was through operating cash flows and available credit under the Company’s Revolving Credit Facility.

A summary of the new tank barge and towboat construction follows:

Capital Expenditures - (Continued)

Funding for future capital expenditures and new barge and towboat construction is expected to be provided through operating cash flows and available credit under the Company’s Revolving Credit Facility.

Treasury Stock Purchases

During the 2006 third quarter, the Company purchased in the open market 162,900 shares of common stock at a total purchase price of $4,789,000, for an average price of $29.40 per share. As of November 6, 2006, the Company had 2,258,000 shares available under its existing repurchase authorization. Historically, treasury stock purchases have been financed through operating cash flows and borrowing under the Company’s Revolving Credit Facility. The Company is authorized to purchase its common stock on the New York Stock Exchange and in privately negotiated transactions. When purchasing its common stock, the Company is subject to price, trading volume and other market considerations. Shares purchased may be used for reissuance upon the exercise of stock options or the granting of other forms of incentive compensation, in future acquisitions for stock or for other appropriate corporate purposes.

Liquidity

The Company generated net cash provided by operating activities of $103,201,000 during the nine months ended September 30, 2006, 3% lower than the $105,977,000 generated during the nine months ended September 30, 2005. The 3% decrease reflected negative cash flows resulting from changes in operating assets and liabilities, partially offset by stronger earnings in the 2006 first nine months versus the 2005 first nine months. The cash flows from changes in operating assets and liabilities were lower in the 2006 first nine months primarily due to a larger accounts receivable increase attributable to increased marine transportation and diesel engine services levels, as well as a larger inventory increase to accommodate increased diesel engine services activity levels and larger incentive compensation payments in 2006 over 2005. In addition, the Company had a smaller increase in accounts payable in the 2006 first nine months versus the 2005 first nine months.

Funds generated are available for acquisitions, capital expenditure projects, treasury stock repurchases, repayments of borrowings associated with each of the above and other operating requirements. In addition to net cash flow provided by operating activities, the Company also had available as of November 3, 2006, $138,906,000 under its Revolving Credit Facility, $121,000,000 under its shelf registration program, subject to mutual agreement and terms, and $4,396,000 available under its Credit Line.

Neither the Company, nor any of its subsidiaries, is obligated on any debt instrument, swap agreement, or any other financial instrument or commercial contract which has a rating trigger, except for pricing grids on its Revolving Credit Facility.

The Company expects to continue to fund expenditures for acquisitions, capital construction projects, treasury stock repurchases, repayment of borrowings, and for other operating requirements from a combination of funds generated from operating activities and available financing arrangements.

Liquidity - (Continued)

During the last three years, inflation has had a relatively minor effect on the financial results of the Company. The marine transportation segment has long-term contracts that generally contain cost escalation clauses whereby certain costs, including fuel, can be passed through to its customers; however, there is typically a 30 to 90 day delay before contracts are adjusted for fuel prices. Spot market rates include the cost of fuel and are subject to market volatility. The repair portion of the diesel engine services segment is based on prevailing current market rates.

Part I Financial Information

Item 3. Quantitative and Qualitative Disclosures about Market Risk

The Company is exposed to risk from changes in interest rates on certain of its outstanding debt. The outstanding loan balances under the Company’s bank credit facilities bear interest at variable rates based on prevailing short-term interest rates in the United States and Europe. A 10% change in variable interest rates would impact the 2006 interest expense by approximately $487,000, based on balances outstanding at December 31, 2005, and change the fair value of the Company’s debt by less than 1%.

From time to time, the Company has utilized and expects to continue to utilize derivative financial instruments with respect to a portion of its interest rate risks to achieve a more predictable cash flow by reducing its exposure to interest rate fluctuations. These transactions generally are interest rate swap agreements which are entered into with major financial institutions. Derivative financial instruments related to the Company’s interest rate risks are intended to reduce the Company’s exposure to increases in the benchmark interest rates underlying the Company’s floating rate senior notes and variable rate bank credit facilities. The Company does not enter into derivative financial instrument transactions for speculative purposes.

Notional amount		Effective date	Termination date	Fixed pay rate	Receive rate
$	100,000	March 2006	February 2013	5.45%	Three-month LIBOR
