KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

NOTES TO CONDENSED FINANCIAL STATEMENTS
(Unaudited)

(1) Basis for Preparation of the Condensed Financial Statements

The condensed financial statements included herein have been prepared by Kirby Corporation and its consolidated subsidiaries ("Kirby" or the "Company"), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Although the Company believes that the disclosures are adequate to make the information presented not misleading, certain information and footnote disclosures, including significant accounting policies normally included in annual financial statements, have been condensed or omitted pursuant to such rules and regulations. It is suggested that these condensed financial statements be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2023. Certain reclassifications have been made to reflect the current presentation of financial information.

Effective January 1, 2024, the power generation revenue source within the distribution and services segment has been broken out from the commercial and industrial and oil and gas revenue sources due to the significance of the power generation market to the Company's growth. This change had no net impact on overall Company or segment revenues and has been reflected retrospectively for all periods presented.

(2) Acquisitions

On May 15, 2024, the Company completed the purchase of 13inland tank barges, with a total capacity of 347,000barrels, and twohigh horsepower towboats from an undisclosed seller for approximately $65.2million in cash. The 13tank barges, including threespecialty barges, transport petrochemicals and refined products on the Mississippi River System and Gulf Intracoastal Waterway. The average age of the 13barges was 15years.

On July 14, 2023, the Company purchased 23inland tank barges with a total capacity of 265,000barrels from an undisclosed seller for $37million in cash. The 23tank barges transport petrochemicals and refined products on the Mississippi River System and the Gulf Intracoastal Waterway. The average age of the 23barges was 14years.

The Company purchased fourinland tank barges from a leasing company for $0.5million in cash during the 2023 third quarter. The Company had been leasing the barges prior to the purchase.

(3) Revenues

The following table sets forth the Company's revenues by major source (in thousands):


	Three Months Ended June 30,		Six Months Ended June 30,
	2024		2023			2024		2023
Marine transportation segment:
Inland transportation	$	391,835		$	351,807		$	777,842	$	689,695
Coastal transportation		92,973			75,155			182,378		149,762
	$	484,808		$	426,962		$	960,220	$	839,457
Distribution and services segment:
Commercial and industrial	$	165,658		$	152,045		$	308,282	$	305,099
Power generation		107,783			99,006			243,452		189,315
Oil and gas		66,141			99,235			120,458		193,821
	$	339,582		$	350,286		$	672,192	$	688,235

Contract liabilities represent advance consideration received from customers, and are recognized as revenue over time or at a point in time as the related performance obligation is satisfied. Revenues recognized during the six months ended June 30, 2024 and 2023 that were included in the opening contract liability balances were $81.5millionand $60.3million, respectively. The Company presents all contract liabilities within the deferred revenues financial statement caption on the balance sheets. The Company did not have any contract assets at June 30, 2024 or December 31, 2023. The Company applies the practical expedient that allows non-disclosure of information about remaining performance obligations that have original expected durations of one yearor less.

(4) Segment Data

The Company's operations are aggregated into tworeportable business segments as follows:

Marine Transportation Segment ("KMT")- Provides marine transportation by United States flagged vessels principally of liquid cargoes throughout the United States inland waterway system, along all three United States coasts, and, to a lesser extent, in United States coastal transportation of dry-bulk cargoes. The principal products transported include petrochemicals, black oil, refined petroleum products, and agricultural chemicals.

Distribution and Services Segment ("KDS")- Provides after-market services and genuine replacement parts for engines, transmissions, reduction gears, and related equipment used in oilfield services, marine, power generation, on-highway, backup power and other industrial applications. The Company also rents equipment including generators, industrial compressors, high capacity lift trucks, and refrigeration trailers for use in a variety of industrial markets, and manufactures and remanufactures oilfield service equipment, including pressure pumping units, electric power generation equipment, and specialized electrical distribution and control equipment.

The Company's tworeportable business segments are managed separately based on fundamental differences in their operations. The Company evaluates the performance of its segments based on the contributions to operating income of the respective segments, before income taxes, interest, gains or losses on disposition of assets, other nonoperating income, noncontrolling interests, accounting changes, and nonrecurring items. Intersegment revenues, based on market-based pricing, of KDS from KMT of $7.5millionand $14.1millionfor the three months and six months ended June 30, 2024, respectively, and $10.3millionand $19.7millionfor the three months and six months ended June 30, 2023, respectively, as well as the related intersegment profit of $0.7millionand $1.4millionfor the three months and six months ended June 30, 2024, respectively, and $1.0millionand $2.0millionfor the three months and six months ended June 30, 2023, respectively, have been eliminated from the tables below.

The following tables set forth the Company's revenues and profit or loss by reportable segment and total assets (in thousands):

(a)

Variable interest rate of 6.6%at June 30, 2024and 6.8% at December 31, 2023.

On July 29, 2022, the Company entered into a credit agreement (the "2027 Credit Agreement") with a group of commercial banks, with JPMorgan Chase Bank, N.A. as the administrative agent bank that allows for a $500million unsecured revolving credit facility (the "2027 Revolving Credit Facility") and a $250million unsecured term loan (the "2027 Term Loan") with a maturity date of July 29, 2027. Norepayments are required until June 30, 2025.Future repayments under the 2027 Term Loan are excluded from short term liabilities because the Company intends to use availability under the 2027 Revolving Credit Facility to repay these amounts upon maturity. Outstanding letters of credit under the 2027 Revolving Credit Facility were $6,000and available borrowing capacity was $426.0millionas of June 30, 2024.

On February 3, 2022, the Company entered into a note purchase agreement for the issuance of $300million of unsecured senior notes with a group of institutional investors, consisting of $60million of 3.46% series A notes ("Series A Notes") and $240million of 3.51% series B notes ("Series B Notes"), each due January 19, 2033(collectively, the "2033 Notes"). The Series A Notes were issued on October 20, 2022, and the Series B Notes were issued on January 19, 2023. No principal payments will be required until maturity.

The Company has a $15million line of credit ("Credit Line") with Bank of America, N.A. ("Bank of America") for short-term liquidity needs and letters of credit, with a maturity date of June 30, 2026. Outstanding letters of credit under the Credit Line were $6.8millionand available borrowing capacity was $8.2millionas of June 30, 2024.

(6) Leases

The Company currently leases various facilities and equipment under cancelable and noncancelable operating leases. The accounting for the Company's leases may require judgments, which include determining whether a contract contains a lease, allocating the consideration between lease and non-lease components, and determining the incremental borrowing rates. Leases with an initial noncancelable term of 12 months or less are not recorded on the balance sheet and related lease expense is recognized on a straight-line basis over the lease term. The Company has also elected to combine lease and non-lease components on all classes of leased assets, except for leased towing vessels, for which the Company estimates approximately 70% of the costs relate to service costs and other non-lease components. Variable lease costs relate primarily to real estate executory costs (i.e. taxes, insurance and maintenance).

(11) Retirement Plans

The Company sponsors a defined benefit plan for certain of its inland vessel personnel and shore based tankermen. The plan benefits are based on an employee's years of service and compensation. The plan assets consist primarily of equity and fixed income securities.

On April 12, 2017, the Company amended its pension plan to cease all benefit accruals for periods after May 31, 2017 for certain participants. Participants grandfathered and not impacted were those, as of the close of business on May 31, 2017, who either (a) had completed 15 yearsof pension service or (b) had attained age 50and completed 10 yearsof pension service. Participants non-grandfathered are eligible to receive discretionary 401(k) plan contributions.

The Company's pension plan funding strategy is to make annual contributions in amounts equal to or greater than amounts necessary to meet minimum government funding requirements. The plan's benefit obligations are 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 an accurate prediction of the pension plan contribution difficult. Based on current pension plan assets and market conditions, the Company does not expect to make a contribution to the Kirby pension plan during 2024.

On February 14, 2018, with the acquisition of Higman Marine, Inc. and its affiliated companies ("Higman"), the Company assumed Higman's pension plan for its inland vessel personnel and office staff. On March 27, 2018, the Company amended the Higman pension plan to close it to all new entrants and cease all benefit accruals for periods after May 15, 2018 for all participants. The Company made contributions of $0.6millionto the Higman pension plan during the six months ended June 30, 2024. The Company expects to make additional contributions of $1.1million during the remainder of 2024.

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. The plan eliminated coverage for future retirees as of December 31, 2011. The Company also has an unfunded defined benefit supplemental executive retirement plan ("SERP") that was assumed in an acquisition in 1999. That plan ceased to accrue additional benefits effective January 1, 2000.

(13) Contingencies and Commitments

On October 13, 2016, the tug Nathan E. Stewart and barge DBL 55, an articulated tank barge and tugboat unit ("ATB") owned and operated by Kirby Offshore Marine, LLC, a wholly owned subsidiary of the Company, ran aground at the entrance to Seaforth Channel on Atholone Island, British Columbia. The grounding resulted in a breach of a portion of the Nathan E. Stewart's fuel tanks causing a discharge of diesel fuel into the water. The United States Coast Guard and the National Transportation Safety Board designated the Company as a party of interest in their investigation as to the cause of the incident. The Canadian authorities including Transport Canada and the Canadian Transportation Safety Board investigated the cause of the incident. On October 10, 2018, the Heiltsuk First Nation filed a civil action in the British Columbia Supreme Court against a subsidiary of the Company, the master and pilot of the tug, the vessels and the Canadian government seeking unquantified damages as a result of the incident. On May 1, 2019, the Company filed a limitation action in the Federal Court of Canada seeking limitation of liability relating to the incident as provided under admiralty law. The Heiltsuk First Nation's civil claim has been consolidated into the Federal Court limitation action as of July 26,

2019 and it is expected that the Federal Court of Canada will decide all claims against the Company. The Company is unable to estimate the potential exposure in the civil proceeding. The Company has various insurance policies covering liabilities including pollution, property, marine and general liability and believes that it has satisfactory insurance coverage for the cost of cleanup and salvage operations as well as other potential liabilities arising from the incident. The Company believes its accrual of such estimated liability is adequate for the incident and does not expect the incident to have a material adverse effect on its business or financial condition.

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 its accrual of such estimated liability is adequate and believes that it has adequate insurance coverage or has meritorious defenses for these other claims and contingencies.

The Company has issued guaranties or obtained standby 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 $31.5millionat June 30, 2024, including $11.6millionin letters of credit and $19.9millionin performance bonds. All of these instruments have an expiration date within two years. The Company does not believe demand for payment under these instruments is likely and expects no material cash outlays to occur regarding these instruments.

The following table summarizes key operating results of the Company (in thousands, except per share amounts):


	Three Months Ended June 30,		Six Months Ended June 30,
	2024		2023			2024			2023
Total revenues	$	824,390		$	777,248			$	1,632,412			$	1,527,692
Net earnings attributable to Kirby	$	83,854		$	57,367			$	153,922			$	98,065
Net earnings per share attributable to Kirby common stockholders - diluted	$	1.43		$	0.95			$	2.62			$	1.63
Net cash provided by operating activities						$	302,607			$	227,949
Capital expenditures						$	169,607			$	171,245

The 2023 first quarter included $3.0 million before taxes, $2.4 million after taxes, or $0.04 per share of costs related to strategic review and shareholder engagement and $2.7 million before taxes, $2.2 million after taxes, or $0.04 per share of other income associated with the interest on the refund from the IRS.

Cash provided by operating activities for the 2024 first six months increased in comparison to the 2023 first six months primarily due to higher business activity levels. For the 2024 first six months, capital expenditures of $169.6 million included $123.1 million in KMT and $46.5 million in KDS and corporate, each more fully described under Cash Flow and Capital Expenditures below.

The Company projects that capital expenditures for 2024 will be in the $300 million to $330 million range. Approximately $200 million to $240 million is associated with marine maintenance capital and improvements to existing inland and coastal marine equipment, and facility improvements. Approximately $90 million is associated with growth capital spending in both segments.

The Company's debt-to-capitalization ratio was 24.3% at June 30, 2024 compared to 24.2% at December 31, 2023. Total equity increased as of June 30, 2024 as compared to December 31, 2023 primarily from net earnings attributable to Kirby of $153.9 million, partially offset by treasury stock purchases of $85.5 million. The Company's debt outstanding as of June 30, 2024 and December 31, 2023 is detailed in Long-Term Financing below.

Marine Transportation

For both the 2024 second quarter and first six months, KMT generated 59% of the Company's revenues compared to 55% for both the 2023 second quarter and first six months. The segment's customers include many of the major petrochemical and refining companies that operate in the United States. Products transported include intermediate materials used to produce many of the end products used widely by businesses and consumers - plastics, fiber, paints, detergents, oil additives and paper, among others, as well as residual fuel oil, ship bunkers, asphalt, gasoline, diesel fuel, heating oil, crude oil, natural gas condensate, and agricultural chemicals. Consequently, KMT is directly affected by the volumes produced by the Company's petroleum, petrochemical, and refining customer base.

The Company also owns shifting operations and fleeting facilities for dry cargo barges and tank barges in the Houston Ship Channel and in Freeport and Port Arthur, Texas, and Lake Charles, Louisiana and a shipyard for building towboats and performing routine maintenance near the Houston Ship Channel. Furthermore, the Company owns a two-thirds interest in Osprey Line, L.L.C., which transports project cargoes and cargo containers by barge.

During the 2024 first six months, the Company brought back into service three inland tank barges, purchased 13 inland tank barges, purchased a newly constructed inland specialty tank barge, chartered one inland tank barge, and retired one inland tank barge, increasing its capacity by approximately 0.4 million barrels.

KMT revenues for both the 2024 second quarter and first six months increased 14% and operating income increased 48% and 66%, respectively, compared to the 2023 second quarter and first six months. The increase in revenues was primarily due to higher term and spot pricing in the inland and coastal markets. The 2024 second quarter was modestly impacted by heavy rains, which briefly closed the Houston Ship Channel, and the closure of two major locks on the lower Mississippi River for repairs. The 2024 and 2023 first quarters were impacted by poor operating conditions including seasonal wind and fog along the Gulf Coast and various lock closures. For both the 2024 second quarter and first six months, the inland tank barge fleet contributed 81% and the coastal fleet contributed 19% of KMT revenues. For both the 2023 second quarter and first six months, the inland tank barge fleet contributed 82% and the coastal fleet contributed 18% of KMT revenues.

Inland tank barge utilization levels averaged in the low to mid-90% range during both the 2024 first and second quarters and the 2023 first quarter, and the low 90% range during the 2023 second quarter. The 2024 second quarter was modestly impacted by heavy rains, which briefly closed the Houston Ship Channel, and the closure of two major locks on the lower Mississippi River for repairs. The 2024 and 2023 first quarters were impacted by high winds and heavy fog along the Gulf Coast and lock delays.

Coastal tank barge utilization levels averaged in the mid to high 90% range during both the 2024 and 2023 first and second quarters.

During both the 2024 second quarter and first six months, approximately 65% of KMT inland revenues were under term contracts and 35% were spot contract revenues. During both the 2023 second quarter and first six months, approximately 55% of KMT inland revenues were under term contracts and 45% were spot contract revenues. Inland time charters during the 2024 second quarter and first six months represented approximately 59% and 60%, respectively, of inland revenues under term contracts compared with 62% and 61% in the 2023 second quarter and first six months, respectively. During the 2024 second quarter and first six months, approximately 100% and 98%, respectively, of KMT coastal revenues were under term contracts and none and 2%, respectively, were under spot contracts. During the 2023 second quarter and first six months, approximately 85% and 80%, respectively, of KMT coastal revenues were under term contracts and 15% and 20%, respectively, were under spot contracts. Coastal time charters represented approximately 97% of coastal revenues under term contracts during both the 2024 second quarter and first six months compared to 90% during both the 2023 second quarter and first six months. Term contracts have contract terms of 12 months or longer, while spot contracts have contract terms of less than 12 months.

The following table summarizes the average range of pricing changes in term and spot contracts renewed during 2024 compared to contracts renewed during the corresponding quarter of 2023:


	Three Months Ended
	March 31, 2024	June 30, 2024
Inland market:
Term increase	9% - 12%	4% - 6%
Spot increase	14% - 17%	14% - 16%
Coastal market (a):
Term increase	19% - 21%	17% - 20%
Spot increase	30% - 32%	23% - 26%

(a)

Spot and term contract pricing in the coastal market are contingent on various factors including geographic location, vessel capacity, vessel type, and product serviced.

Effective January 1, 2024, annual escalators for labor and the producer price index on a number of inland multi-year contracts resulted in rate increases on those contracts of approximately 9.5%, excluding fuel.

KMT operating margin was 19.6% and 18.5% for the 2024 second quarter and first six months, respectively, compared to 15.0% and 12.8% for the 2023 second quarter and first six months, respectively.

Distribution and Services

KDS sells genuine replacement parts, provides service mechanics to overhaul and repair engines, transmissions, reduction gears and related oilfield services equipment, rebuilds component parts or entire diesel engines, transmissions and reduction gears, and related equipment used in oilfield services, marine, power generation, on-highway, backup power and other industrial applications. The Company also rents equipment including generators, industrial compressors, high capacity lift trucks, and refrigeration trailers for use in a variety of industrial markets, manufactures and remanufactures oilfield service equipment, including pressure pumping units, and manufactures cementing and pumping equipment as well as coil tubing and well intervention equipment, electric power generation equipment, and specialized electric distribution and control equipment.

For both the 2024 second quarter and first six months, KDS generated 41% of the Company's revenues, of which 83% and 78%, respectively, were generated from service and parts and 17% and 22%, respectively, from manufacturing. The results of KDS are largely influenced by the economic cycles of the oil and gas, marine, power generation, on-highway, and other related industrial markets.

KDS revenues for the 2024 second quarter and first six months decreased 3% and 2%, respectively, and operating income decreased 1% and 2%, respectively, compared with the 2023 second quarter and first six months. In the commercial and industrial market, revenues increased compared to the 2023 second quarter and first six months, as higher business levels in marine repair were partially offset by lower on-highway activity. Operating income in the commercial and industrial market was up compared to the 2023 second quarter and first six months mainly due to sales mix. For the 2024 second quarter and first six months, the commercial and industrial market contributed 49% and 46%, respectively, of KDS revenues.

In the power generation market, revenues and operating income increased compared to the 2023 second quarter and first six months with several large project awards from data center customers as well as other backup power industrial customers. For the 2024 second quarter and first six months, the power generation market contributed 32% and 36%, respectively, of KDS revenues.

In the oil and gas market, revenues and operating income declined compared to the 2023 second quarter and first six months due to lower levels of conventional oilfield activity which resulted in decreased demand for new transmissions and parts, partially offset by deliveries of electric fracturing equipment. For the 2024 second quarter and first six months, the oil and gas market contributed 19% and 18%, respectively, of KDS revenues.

KDS operating margin was 8.7% and 7.7% for the 2024 second quarter and first six months, respectively, compared to 8.5% and 7.6% for the 2023 second quarter and first six months, respectively.

Outlook

Overall, the Company expects to deliver improved financial results in 2024. In KMT, barge utilization and customer demand remain strong, and rates continue to increase. In KDS, demand for products and services remains steady, and the Company continues to receive new orders in manufacturing. The Company remains mindful of the ever-changing economic landscape related to the impact of continued high interest rates, and possible recessionary headwinds as it moves through 2024.

In the inland marine transportation market, the Company anticipates continued positive market dynamics for the remainder of 2024 with steady customer demand and limited new barge construction in the industry. In addition, many industry units are scheduled for maintenance in 2024 and 2025. The Company expects inland barge utilization rates to remain in the low to mid-90% range throughout the remainder of the year. In coastal marine, strong customer demand is expected throughout the year with barge utilization in the low to mid-90% range.

KDS results are largely influenced by power generation needs, as well as the cycles of the oil and gas, marine, on-highway and other related industrial markets. Despite economic uncertainty, the Company expects to yield incremental demand for OEM products, parts, and services in the segment. In commercial and industrial, the demand outlook in marine repair is strong while on-highway is somewhat weak with the exception of Thermo King refrigeration products and services. In power generation, the Company anticipates continued strong growth as data center demand and the need for backup power is strong. In oil and gas, activity levels are lower but seem to be bottoming with improved revenues and operating income in the 2024 second quarter as compared to the 2024 first quarter. The Company anticipates extended lead times for certain OEM products to continue contributing to a volatile delivery schedule of new products in 2024 and into 2025.

Acquisitions

On May 15, 2024, the Company completed the purchase of 13 inland tank barges, with a total capacity of 347,000 barrels, and two high horsepower towboats from an undisclosed seller for approximately $65.2 million in cash. The 13 tank barges, including three specialty barges, transport petrochemicals and refined products on the Mississippi River System and Gulf Intracoastal Waterway. The average age of the 13 barges was 15 years. Financing of the equipment acquisition was through borrowings under the Company's revolving credit facility.

On July 14, 2023, the Company purchased 23 inland tank barges with a total capacity of 265,000 barrels from an undisclosed seller for $37 million in cash. The 23 tank barges transport petrochemicals and refined products on the Mississippi River System and the Gulf Intracoastal Waterway. The average age of the 23 barges was 14 years. Financing of the equipment acquisition was through borrowings under the Company's revolving credit facility.

The Company purchased four inland tank barges from a leasing company for $0.5 million in cash during the 2023 third quarter. The Company had been leasing the barges prior to the purchase. Financing of the equipment acquisition was through borrowings under the Company's revolving credit facility.

KMT revenues for both the 2024 second quarter and first six months increased 14% and operating income increased 48% and 66%, respectively, compared to the 2023 second quarter and first six months. The increase in revenues for the 2024 second quarter and first six months was primarily due to higher term and spot pricing in the inland and coastal markets. The 2024 second quarter was modestly impacted by heavy rains, which briefly closed the Houston Ship Channel, and the closure of two major locks on the lower Mississippi River for repairs. The 2024 and 2023 first quarters were impacted by poor operating conditions including seasonal wind and fog along the Gulf Coast and various lock closures. For both the 2024 second quarter and first six months, the inland tank barge fleet

contributed 81% and the coastal fleet contributed 19% of KMT revenues. For both the 2023 second quarter and first six months, the inland tank barge fleet contributed 82% and the coastal fleet contributed 18% of KMT revenues.

Coastal tank barge utilization levels averaged in the mid to high 90% range during both the 2024 and 2023 first and second quarters.

The petrochemical market, which is the Company's largest market, contributed 52% and 51% of KMT revenues for the 2024 second quarter and first six months, respectively, reflecting increased rates, volumes and utilization from Gulf Coast petrochemical plants as a result of improved economic conditions and a reduced supply of barges across the industry due to a heavier than normal maintenance cycle as compared to the 2023 second quarter and first six months.

The black oil market, which contributed 25% and 26% of KMT revenues for the 2024 second quarter and first six months, respectively, reflected stable demand as refinery utilization and production levels of refined petroleum products and fuel oils increased. During the 2024 first six months, the Company transported crude oil and natural gas condensate produced from major U.S. shale basins along the Gulf Intracoastal Waterway with inland vessels and in the Gulf of Mexico with coastal equipment. Additionally, the Company transported volumes of Utica natural gas condensate downriver from the Mid-Atlantic to the Gulf Coast.

The refined petroleum products market, which contributed 20% of KMT revenues for both the 2024 second quarter and first six months, reflected stable volumes in the inland market with steady refinery utilization and product levels as compared to the 2023 second quarter and first six months.

The agricultural chemical market, which contributed 3% of KMT revenues for both the 2024 second quarter and first six months, reflected improved demand for transportation of both domestically produced and imported products as compared to the 2023 second quarter and first six months.

For the 2024 second quarter, inland operations incurred 3,334 delay days, 44% more than the 2,317 delay days that occurred during the 2023 second quarter. For the 2024 first six months, inland operations incurred 6,841 delay days, 6% more than the 6,442 delay days that occurred during the 2023 first six months. Delay days measure the lost time incurred by a tow (towboat and one or more tank barges) during transit when the tow is stopped due to weather, lock conditions, or other navigational factors. Delay days reflected the modest impact of heavy rains, which briefly closed the Houston Ship Channel, and the closure of two major locks on the lower Mississippi River for repairs during the 2024 second quarter and poor operating conditions due to heavy wind and fog along the Gulf Coast and lock delays during the 2024 and 2023 first quarters.

The following table summarizes the average range of pricing changes in term and spot contracts renewed during 2024 compared to contracts renewed during the corresponding quarter of 2023:


	Three Months Ended

Spot and term contract pricing in the coastal market are contingent on various factors including geographic location, vessel capacity, vessel type, and product serviced.

Marine Transportation Costs and Expenses

Costs and expenses for the 2024 second quarter and first six months increased 8% and 7%, respectively, compared to the 2023 second quarter and first six months. Costs of sales and operating expenses for the 2024 second quarter and first six months increased 9% and 8%, respectively, compared with the 2023 second quarter and first six months. The increase during the 2024 second quarter and first six months reflected improved business activity levels and inflationary cost pressures, partially offset by lower fuel costs.

The inland marine transportation fleet operated an average of 287 towboats during the 2024 second quarter, of which an average of 74 were chartered, compared to 281 during the 2023 second quarter, of which an average of 66 were chartered. The Company charters in or releases chartered towboats in an effort to balance horsepower needs with current requirements, taking into account variability in demand or anticipated demand, addition or removal of tank barges from the fleet, chartered towboat availability, and weather or water conditions. The Company has historically used chartered towboats for approximately one-fourth of its horsepower requirements.

During the 2024 second quarter, inland operations consumed 12.1 million gallons of diesel fuel compared to 12.2 million gallons consumed during the 2023 second quarter. The average price per gallon of diesel fuel consumed during the 2024 second quarter was $2.83 per gallon compared with $2.87 per gallon for the 2023 second quarter. During the 2024 first six months, inland operations consumed 24.0 million gallons of diesel fuel compared to 24.4 million gallons consumed during the 2023 first six months. The average price per gallon of diesel fuel consumed during the 2024 first six months was $2.83 per gallon compared with $3.09 per gallon for the 2023 first six months. Fuel escalation and de-escalation clauses are typically included in term contracts and are designed to rebate fuel costs when prices decline and recover additional fuel costs when fuel prices rise; however, there is generally a 30 to 120 day delay before contracts are adjusted. Spot contracts do not have escalators for fuel.

Selling, general and administrative expenses for the 2024 second quarter and first six months decreased 3% and increased 2%, respectively, compared to the 2023 second quarter and first six months. The decrease in selling, general and administrative expenses for the 2024 second quarter as compared to the 2023 second quarter was primarily due to lower legal costs, which was partially offset by higher business activity levels and inflationary cost pressures. The increase in selling, general and administrative expenses for the 2024 first six months as compared to the 2023 first six months was primarily due to higher business activity levels and inflationary cost pressures, which was partially offset by lower legal costs. Both the 2024 second quarter and first six months were also impacted by salary and wage increases that went into effect July 1, 2023.

Marine Transportation Operating Income and Operating Margin

KMT operating income for the 2024 second quarter and first six months increased 48% and 66%, respectively, compared with the 2023 second quarter and first six months. The 2024 second quarter operating margin was 19.6% compared with 15.0% for the 2023 second quarter. The 2024 first six months operating margin was 18.5% compared with 12.8% for the 2023 first six months. The increases in operating income and operating margin were primarily due to higher term and spot contract pricing in the inland and coastal markets as a result of improving business activity levels, high utilization and a reduced supply of barges across the industry due to a heavier than normal maintenance cycle.

Inventories - net decreased by 2% primarily due to strong deliveries of power generation units during the 2024 first six months.

Property and equipment, net of accumulated depreciation, at June 30, 2024 increased 3% compared with December 31, 2023. The increase reflected $171.6 million of capital additions (including an increase in accrued capital expenditures of $2.0 million) and a $65.2 million equipment acquisition in the 2024 second quarter, partially offset by $112.8 million of depreciation expense and $10.4 million of property disposals more fully described under Cash Flow and Capital Expenditures below.

Other intangibles, net, as of June 30, 2024 decreased 10% compared with December 31, 2023, due to amortization during the 2024 first six months.

Other assets as of June 30, 2024 decreased 3% compared with December 31, 2023, primarily due to amortization of drydock expenditures, partially offset by additional deferred major maintenance drydock expenditures incurred during the 2024 first six months.

Current liabilities as of June 30, 2024 increased 1% compared with December 31, 2023. Income taxes payable increased by $8.7 million as the Company expects to utilize its remaining federal net operating losses during 2024 due to improved profitability. Accounts payable decreased 1% primarily due to timing of inventory purchases. Accrued liabilities decreased 8% primarily from payment during the 2024 first quarter of employee incentive compensation accrued during 2023. Deferred revenue increased 14% primarily due to deposits on equipment expected to be shipped later in 2024 in KDS.

Long-term debt, net - less current portion, as of June 30, 2024 increased 3% compared with December 31, 2023, primarily reflecting borrowings under the 2027 Revolving Credit Facility.

Deferred income taxes as of June 30, 2024 increased 3% compared with December 31, 2023, primarily reflecting the deferred tax provision of $23.9 million.

Total equity as of June 30, 2024 increased 2% compared with December 31, 2023. The increase was primarily due to the net earnings attributable to Kirby of $153.9 million, amortization of share-based compensation of $9.4 million, and stock option exercises of $4.1 million, partially offset by treasury stock purchases of $85.5 million and tax withholdings of $5.3 million on RSU vestings.

On July 29, 2022, the Company entered into the 2027 Credit Agreement with a group of commercial banks, with JPMorgan Chase Bank, N.A. as the administrative agent bank that allows for a $500 million 2027 Revolving Credit Facility and a $250 million 2027 Term Loan with a maturity date of July 29, 2027. No repayments are required until June 30, 2025. Future repayments under the 2027 Term Loan are excluded from short term liabilities because the Company intends to use availability under the 2027 Revolving Credit Facility to repay these amounts upon maturity. Outstanding letters of credit under the 2027 Revolving Credit Facility were $6,000 and available borrowing capacity was $426.0 million as of June 30, 2024.

On February 3, 2022, the Company entered into a note purchase agreement for the 2033 Notes with a group of institutional investors, consisting of $60 million Series A Notes and $240 million Series B Notes, each due January 19, 2033. The Series A Notes were issued on October 20, 2022, and the Series B Notes were issued on January 19, 2023. No principal payments will be required until maturity.

The Company has a $15 million Credit Line with Bank of America for short-term liquidity needs and letters of credit, with a maturity date of June 30, 2026. Outstanding letters of credit under the Credit Line were $6.8 million and available borrowing capacity was $8.2 million as of June 30, 2024.

As of June 30, 2024, the Company was in compliance with all covenants under its debt instruments. For additional information about the Company's debt instruments, see Note 5, Long-Term Debt, of the Notes to Condensed Financial Statements (Unaudited) as well as Note 5, Long-Term Debt, in the Company's Annual Report on Form 10-K for the year ended December 31, 2023.

Cash Flow and Capital Expenditures

The Company generated positive operating cash flows during the 2024 first six months with net cash provided by operating activities of $302.6 million compared with $227.9 million for the 2023 first six months, a 33% increase. The improvement in operating cash flows was due to higher revenues and operating income in KMT and a favorable change in inventories, primarily due to timing of shipments. The 2023 first six months includes the receipt of the Internal Revenue Service refund of $70.4 million plus accrued interest in April 2023. Increases in KMT revenues and operating income were driven by higher term and spot contract pricing during the 2024 first six months. During the 2024 and 2023 first six months, the Company generated cash of $9.1 million and $20.5 million, respectively, from proceeds from the disposition of assets, and $4.1 million and $0.1 million, respectively, from proceeds from the exercise of stock options.

For the 2024 first six months, cash generated was used for capital expenditures of $169.6 million, including $111.1 million associated with marine maintenance capital and improvements to existing inland and coastal marine equipment and facility improvements, as well as $58.5 million for growth spending in both segments. The growth spending is related to inland equipment construction and equipment for use in a variety of KDS markets including electric fracturing equipment, generators, and other related equipment.

Treasury Stock Purchases

During the 2024 first six months, the Company purchased 870,770 shares of its common stock for $85.5 million, at an average price of $98.15 per share. Subsequent to June 30, 2024 and through August 8, 2024, the Company purchased an additional 98,854 shares of its common stock for $11.1 million, at an average price of $111.85 per share. As of August 8, 2024, the Company had approximately 3.6 million shares available under its existing purchase authorizations. Historically, treasury stock purchases have been financed through operating cash flows and borrowings 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. For more information about stock purchases in the 2024 second quarter, see Part II, Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Liquidity

Funds generated from operations are available for acquisitions, capital expenditure projects, common stock purchases, repayments of borrowings, and for other corporate and operating requirements. In addition to net cash flows provided by operating activities, as of August 8, 2024 the Company also had cash and cash equivalents of $53.5 million, availability of $444.9 million under its 2027 Revolving Credit Facility, and $8.2 million 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 the pricing grid on its 2027 Credit Agreement.

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

The 2027 Revolving Credit Facility's commitment is in the amount of $500 million and matures July 29, 2027. The $500 million 4.2% senior unsecured notes do not mature until March 1, 2028 and require no prepayments. The 2033 Notes do not mature until January 19, 2033 and require no prepayments. The 2027 Term Loan in the amount of $250 million is subject to quarterly installments, beginning June 30, 2025, in increasing percentages of the original principal amount of the loan, with the remaining unpaid balance of approximately $43.8 million payable on July 29, 2027, assuming no prepayments. The 2027 Term Loan is prepayable, in whole or in part, without penalty.

There are numerous factors that may negatively impact the Company's cash flows in 2024. For a list of significant risks and uncertainties that could impact cash flows, see Note 13, Contingencies and Commitments, of the Notes to Condensed Financial Statements (Unaudited), and Item 1A - Risk Factors and Note 14, Contingencies and Commitments, in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. Amounts available under the Company's existing financial arrangements are subject to the Company continuing to meet the covenants of the credit facilities as described in Note 5, Long-Term Debt, of the Notes to Condensed Financial Statements (Unaudited) as well as Note 5, Long-Term Debt, in the Company's Annual Report on Form 10-K for the year ended December 31, 2023.

The Company has issued guaranties or obtained standby 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 $31.5 million at June 30, 2024, including $11.6 million in letters of credit and $19.9 million in performance bonds. All of these instruments have an expiration date within two 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.

KMT term contracts typically contain fuel escalation clauses, or the customer pays for the fuel. However, there is generally a 30 to 120 day delay before contracts are adjusted depending on the specific terms of the contract. In general, the fuel escalation clauses are effective over the long-term in allowing the Company to recover changes in fuel costs due to fuel price changes. However, the short-term effectiveness of the fuel escalation clauses can be affected by a number of factors including, but not limited to, specific terms of the fuel escalation formulas, fuel price volatility, navigating conditions, tow sizes, trip routing, and the location of loading and discharge ports that may result in the Company over or under recovering its fuel costs. The Company's spot contract rates generally reflect current fuel prices at the time the contract is signed but do not have escalators for fuel.

The Company has certain mechanisms designed to help mitigate the impacts of rising costs. For example, KMT has long-term contracts which generally contain cost escalation clauses whereby certain costs, including fuel as noted above, can be largely passed through to its customers. Spot contract rates include the cost of fuel and are subject to market volatility. In KDS, the cost of major components for large manufacturing orders is secured with suppliers at the time a customer order is finalized, which somewhat limits exposure to inflation. The repair portion of KDS is based on prevailing current market rates.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

For quantitative and qualitative disclosures about market risk, see Part II, Item 7A, "Quantitative and Qualitative Disclosures About Market Risk," in the Company's Annual Report on Form 10-K. The Company's exposure to market risk has not changed materially since December 31, 2023.

Item 4. Controls and Procedures

Disclosure Controls and Procedures. The Company's management, with the participation of the Chief Executive Officer and the Chief Financial Officer, has evaluated the Company's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 ("Exchange Act")), as of June 30, 2024, as required by Rule 13a-15(b) under the Exchange Act. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that, as of June 30, 2024, the disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms and (ii) is accumulated and communicated to the Company's management, including the Chief Executive Officer and the Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Changes in Internal Control Over Financial Reporting. There were no changes in the Company's internal control over financial reporting during the quarter ended June 30, 2024 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.
