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 (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, 2020. Certain reclassifications have been made to reflect the current presentation of financial information.

Accounting Standard Adoption

In December 2019, the Financial Accounting Standards Board issued Accounting Standards Update 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”) which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740, Income Taxes. The Company adopted ASU 2019-12 on January 1, 2021. There was no material impact on the Company’s financial statements or disclosures upon adoption of ASU 2019-12.

(2) Acquisition

During the nine months ended September 30, 2021, the Company purchased four inland tank barges from a leasing company for $7,470,000 in cash. The Company had been leasing the barges prior to the purchase.

Contract liabilities represent advance consideration received from customers, and are recognized as revenue over time as the related performance obligation is satisfied. Revenues recognized during the nine months ended September 30, 2021 and 2020 that were included in the opening contract liability balances were $40,315,000 and $37,153,000, 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 September 30, 2021 or December 31, 2020. The Company applies the practical expedient that allows non-disclosure of information about remaining performance obligations that have original expected durations of one year or less.

(4) Segment Data

The Company’s operations are aggregated into two reportable business segments as follows:

Marine Transportation — 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, in Alaska and Hawaii 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.

7

Distribution and Services — Provides after-market services and parts for engines, transmissions, reduction gears and related equipment used in oilfield service, marine, power generation, on-highway, and other industrial applications. The Company also rents equipment including generators, industrial compressors, railcar movers, and high capacity lift trucks for use in a variety of industrial markets, and manufactures and remanufactures oilfield service equipment, including pressure pumping units, for land-based oilfield service customers.

The Company’s two reportable 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 the distribution and services segment from the marine transportation segment of $5,436,000 and $17,593,000 for the three months and nine months ended September 30, 2021, respectively, and $6,768,000 and $23,115,000 for the three months and nine months ended September 30, 2020, respectively, as well as the related intersegment profit of $543,000 and $1,759,000 for the three months and nine months ended September 30, 2021, respectively, and $676,000 and $2,311,000 for the three months and nine months ended September 30, 2020, respectively, have been eliminated from the tables below.

The Company has an amended and restated credit agreement (the “Credit Agreement”) with a group of commercial banks, with JPMorgan Chase Bank, N.A. as the administrative agent bank, allowing for an $850,000,000 unsecured revolving credit facility (“Revolving Credit Facility”) and an unsecured term loan (“Term Loan”) with a maturity date of March 27, 2024. The Term Loan is due on March 27, 2024 and is prepayable, in whole or in part, without penalty. During the nine months ended September 30, 2021, the Company repaid $15,000,000 under the Term Loa n. During October 2021, the Company repaid $20,000,000 under the Term Loan. Outstanding letters of credit under the Revolv ing Credit Facility were $5,063,000 and available borrowing capacity was $844,937,000 as of September 30, 2021. Outstanding letters of credit under the $10,000,000 credit line were $1,299,000 and available borrowing capacity was $8,701,000 as of September 30, 2021.

(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 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).

(7) Impairments and Other Charges

During the three months ended September 30, 2021, the Company decided to exit the Hawaii market, selling marine transportation equipment including four coastal tank barges, seven coastal tugboats, and certain other assets for aggregate cash proceeds of $17,200,000. In addition, as of September 30, 2021, the Company has retired and classified as held for sale, an additional 12 coastal tank barges and four coastal tugboats which were underutilized. The sales and retirements of coastal marine transportation equipment resulted in an aggregate non‑cash impairment charge of $97,508,000 to reduce the carrying value of these assets to their estimated sales prices, net of costs to sell.

As a result of the sale of the Hawaii marine transportation equipment, and the decision to retire certain additional underutilized coastal tank barges and tugboats, the Company concluded that a triggering event had occurred and performed interim quantitative impairment tests as of September 30, 2021 for certain of the marine transportation segment's long-lived assets and goodwill within the coastal marine market.

The Company determined the estimated fair value of such long-lived assets using a combination of a cost approach, a discounted cash flow analysis, and a market approach. The Company determined the estimated fair value of the reporting unit using a combination of a discounted cash flow analysis and a market approach for comparable companies. These analyses included management’s judgment regarding short-term and long-term internal forecasts, updated for recent events, appropriate discount rates, and capital expenditures using inputs characteristic of a Level 3 fair value measurement.

In performing the impairment test of certain long-lived assets within the marine transportation segment, the Company determined that the carrying value of certain long-lived assets, including certain coastal marine transportation equipment and operating lease right-of-use assets, were no longer recoverable, resulting in a non-cash impairment charge of $24,152,000 during the three months ended September 30, 2021 to reduce such long-lived assets to fair value.

10

Based upon the results of the goodwill impairment test, the Company concluded that the carrying value of one reporting unit in the marine transportation segment exceeded its estimated fair value. The carrying value of the reporting unit, including goodwill, and after recording impairments of long-lived assets identified above, exceeded its estimated fair value, resulting in a non-cash goodwill impairment charge of $219,052,000 for the three months ended September 30, 2021.

The following table summarizes the changes in goodwill during 2021 (in thousands):

|  | Marine Transportation |  |  | Distribution and Services |  |  | Total |
Balance at December 31, 2020 (gross) |  | $ | 505,784 |  |  | $ | 560,155 |  |  | $ | 1,065,939 |
Accumulated impairment and amortization |  |  | (18,574 | ) |  |  | (389,565 | ) |  |  | (408,139 | )
Balance at December 31, 2020 |  |  | 487,210 |  |  |  | 170,590 |  |  |  | 657,800 |
Impairment |  |  | (219,052 | ) |  |  | — |  |  |  | (219,052 | )
Balance at September 30, 2021 |  |  | 505,784 |  |  |  | 560,155 |  |  |  | 1,065,939 |
Accumulated impairment and amortization |  |  | (237,626 | ) |  |  | (389,565 | ) |  |  | (627,191 | )

During the first quarter of 2020, Kirby’s market capitalization declined significantly compared to the 2019 fourth quarter. Over the same period, the overall United States stock market also declined significantly amid market volatility. In addition, as a result of uncertainty surrounding the outbreak of COVID-19 and a sharp decline in oil prices during the 2020 first quarter, many of the Company’s oil and gas customers responded by quickly cutting 2020 capital spending budgets and activity levels quickly declined. Lower activity levels resulted in a decline in drilling activity, resulting in lower demand for new and remanufactured oilfield equipment and related parts and service in the distribution and services segment. As a result, the Company concluded that a triggering event had occurred and performed interim quantitative impairment tests as of March 31, 2020 for certain of the distribution and services segment’s long-lived assets and goodwill.

In performing the impairment test of long-lived assets within the distribution and services segment, the Company determined that the carrying value of certain long-lived assets, including property and equipment as well as intangible assets associated with customer relationships, tradenames, and distributorships, were no longer recoverable, resulting in an impairment charge of $165,304,000 (including $148,909,000 impairment of intangible assets other than goodwill and $16,395,000 impairment of property and equipment) to reduce such long-lived assets to fair value during the three months ended March 31, 2020.

Based upon the results of the goodwill impairment test, the Company concluded that the carrying value of one reporting unit in the distribution and services segment exceeded its estimated fair value. For the three months ended March 31, 2020, the goodwill impairment charge of $387,970,000 was calculated as the amount that the carrying value of the reporting unit, including goodwill, and after recording impairments of long-lived assets identified above, exceeded its estimated fair value, incorporating all tax impacts caused by the recognition of the impairment loss.

In addition, the Company determined cost exceeded net realizable value for certain oilfield and pressure pumping related inventory, resulting in an $8,000,000 non-cash write-down during the three months ended March 31, 2020.

The amendment to the Plan was subsequently approved at the Annual Meeting of Stockholders on April 27, 2021. At September 30, 2021, there wer e 2,228,857 shares available for future grants under the Plan.

During the nine months ended September 30, 2021, the Company grante d 311,016 restricted stock units (“RSUs”) to selected officers and other key employees under the Plan, the majority of which vest ratably over five years.

The restricted stock vests six months after the date of grant except that restricted stock granted in lieu of cash director fees vests in equal quarterly increments through March 31, 2022.

(9) Taxes on Income

On March 27, 2020, the United States Congress passed and the President signed the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) into law to address the COVID-19 pandemic. One provision of the CARES Act allowed net operating losses generated in 2018 through 2020 to be carried back up to five years. Pursuant to this provision of the CARES Act, the Company recorded a net federal current benefit for taxes on income for the nine months ended September 30, 2020 due to carrying back net operating losses generated between 2018 and 2020 used to offset taxable income generated between 2013 and 2017. Net operating losses carried back to tax years 2013 through 2017 were applied at a federal tax rate of 35% applicable to those tax years, compared to a 21% tax rate effective at September 30, 2020. Net operating losses generated in 2018 and 2019 were used to offset taxable income generated between 2013 and 2017 taxed at 35% resulting in a tax benefit of $58,746,000.

At September 30, 2021 and December 31, 2020, the Company had a federal income tax receivable of $70,959,000 and $188,177,000, respectively, included in Accounts Receivable – Other on the balance sheets. During the three months ended March 31, 2021, the Company received a tax refund of $119,493,000, including accrued interest, for its 2019 federal tax return related to net operating losses being carried back to offset taxable income generated between 2014 and 2017.

(12) 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 years of pension service or (b) had attained age 50 and completed 10 years of pension service. Participants non-grandfathered are eligible to receive discretionary 401(k) plan contributions.

13

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 2021.

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 a contribution of $479,000 to the Higman pension plan during the nine months ended September 30, 2021. The Company does not expect to make any additional contributions during 2021.

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 limits cost increases in the Company’s contribution to 4% per year. 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.

(14) Contingencies and Commitments

On May 10, 2019, two tank barges and a towboat, the M/V Voyager, owned and operated by Kirby Inland Marine, LP (“Kirby Inland Marine”), a wholly owned subsidiary of the Company, were struck by the LPG tanker, the Genesis River, in the Houston Ship Channel. The bow of the Genesis River penetrated the Kirby 30015T and capsized the MMI 3014. The collision penetrated the hull of the Kirby 30015T causing its cargo, reformate, to be discharged into the water. The United States Coast Guard (“USCG”) and the National Transportation Safety Board (“NTSB”) designated the owner and pilot of the Genesis River as well as the subsidiary of the Company as parties of interest in their investigation into the cause of the incident. On June 19, 2019, the Company filed a limitation action in the U.S. District Court of the Southern District of Texas ‑ Galveston Division seeking limitation of liability and asserting that the Genesis River and her owner/manager are at fault for damages including removal costs and claims under the Oil Pollution Act of 1990 and maritime law. Multiple claimants have filed claims in the limitation seeking damages under the Oil Pollution Act of 1990. The court bifurcated the matter into two trials, the first to determine liability amongst the parties and the second to assess damages. The Company entered into a settlement agreement resolving claims of natural resource damage arising out of the spill. Under the agreement, the Company agreed to pay state and federal natural resource trustees $2,102,000. The liability trial was conducted during the week of February 2, 2021. The Court issued its decision on July 8, 2021, finding that the Genesis River was solely at fault and no liability on the part of Kirby Inland Marine. No appeal was filed by the Genesis River. The Company and its insurance carriers are collecting the $20,206,000 judgment from the Genesis River and its interests.

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 USCG and the NTSB 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.

15

On March 22, 2014, two tank barges and a towboat, the M/V Miss Susan, owned by Kirby Inland Marine, were involved in a collision with the M/S Summer Wind on the Houston Ship Channel near Texas City, Texas. The lead tank barge was damaged in the collision resulting in a discharge of intermediate fuel oil from one of its cargo tanks. The Company is participating in the natural resource damage assessment and restoration process with federal and state government natural resource trustees. The Company believes it has adequate insurance coverage for pollution, marine and 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 $21,199,000 at September 30, 2021, including $13,847,000 in letters of credit and $7,352,000 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 regarding these instruments.

Overview

The Company is the nation’s largest domestic tank barge operator, transporting bulk liquid products throughout the Mississippi River System, on the Gulf Intracoastal Waterway, coastwise along all three United States coasts, and in Alaska and Hawaii. The Company transports petrochemicals, black oil, refined petroleum products and agricultural chemicals by tank barge. Through its distribution and services segment, the Company provides after-market service and parts for engines, transmissions, reduction gears and related equipment used in oilfield services, marine, power generation, on-highway, and other industrial applications. The Company also rents equipment including generators, industrial compressors, railcar movers, and high capacity lift trucks for use in a variety of industrial markets, and manufactures and remanufactures oilfield service equipment, including pressure pumping units, for land-based oilfield service customers.

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

|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
|  | 2021 |  |  | 2020 |  |  | 2021 |  |  | 2020 |

Net earnings (loss) per share attributable to Kirby common stockholders – diluted |  | $ | (4.41 | ) |  | $ | 0.46 |  |  | $ | (4.30 | ) |  | $ | (4.92 | )
Net cash provided by operating activities |  |  |  |  |  |  |  | $ | 280,362 |  |  | $ | 359,763 |
Capital expenditures |  |  |  |  |  |  |  | $ | 71,968 |  |  | $ | 129,371 |

The 2021 third quarter included $340,713,000 before taxes, $275,068,000 after taxes, or $4.58 per share, non-cash charges related to impairment of long-lived assets related to coastal marine transportation equipment and impairment of goodwill in the marine transportation segment. See Note 7, Impairments and Other Charges in the financial statements for additional information.

The 2020 first quarter included $561,274,000 before taxes, $433,341,000 after taxes, or $7.24 per share, non-cash charges related to inventory write-downs, impairment of long-lived assets, including intangible assets and property and equipment, and impairment of goodwill in the distribution and services segment. See Note 7, Impairments and Other Charges in the financial statements for additional information. In addition, the 2020 first quarter was favorably impacted by an income tax benefit of $50,824,000, or $0.85 per share related to net operating losses generated in 2018 and 2019 used to offset taxable income generated between 2013 and 2017. See Note 9, Taxes on Income in the financial statements for additional information.

17

Cash provided by operating activities for the 2021 first nine months decreased primarily due to lower revenues and operating income in the marine transportation segment, partially offset by the receipt of a tax refund of $119,493,000, including accrued interest, for the Company’s 2019 federal tax return. For the 2021 first nine months, capital expenditures of $71,968,000 included $61,565,000 in the marine transportation segment and $10,403,000 in the distribution and services segment and corporate, more fully described under cash flow and capital expenditures below.

The Company projects that capital expenditures for 2021 will be in the $120,000,000 to $130,000,000 range. The 2021 construction program will consist of approximately $10,000,000 for the construction of new inland towboats, $95,000,000 to $100,000,000 primarily for capital upgrades and improvements to existing marine equipment and facilities, and $15,000,000 to $20,000,000 for new machinery and equipment, facilities improvements, and information technology projects in the distribution and services segment and corporate.

The Company’s debt-to-capitalization ratio decreased to 29.8% at September 30, 2021 from 32.2% at December 31, 2020, primarily due to repayments under the Revolving Credit Facility and Term Loan in the 2021 first nine months, partially offset by a decrease in total equity, primarily due to the net loss attributable to Kirby of $257,915,000. The Company’s debt outstanding as of September 30, 2021 and December 31, 2020 is detailed in Long-Term Financing below.

Marine Transportation

For the 2021 third quarter and first nine months, the Company’s marine transportation segment generated 57% and 59%, respectively, of the Company’s revenues. 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, the Company’s marine transportation business is directly affected by the volumes produced by the Company’s petroleum, petrochemical and refining customer base.

The following table summarizes the Company’s marine transportation fleet:

The Company also owns shifting operations and fleeting facilities for dry cargo barges and tank barges on 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, as well as a two-thirds interest in Osprey Line, L.L.C., which transports project cargoes and cargo containers by barge.

During the 2021 first nine months, the Company retired 26 inland tank barges and returned four leased barges. The net result was a decrease of 30 inland tank barges and approximately 907,000 barrels of capacity.

The Company’s marine transportation segment’s revenues for the 2021 third quarter and first nine months increased 6% and decreased 12%, respectively, and operating income decreased 48% and 72%, respectively, compared with the 2020 third quarter and first nine months revenues and operating income. The increase in revenues for the 2021 third quarter was primarily due to increased fuel rebills in the inland and coastal markets and increased tank barge utilization in the inland market. The decreases for the 2021 first nine months were primarily due to reduced barge utilization in the inland and coastal markets as well as reduced term and spot pricing in the inland market when compared to 2020. The decreases were partially offset by the addition of the Savage Inland Marine, LLC (“Savage”) fleet acquired on April 1, 2020. The 2021 third quarter benefited from improving business activity and inland market barge utilization which were largely offset by reduced term pricing when compared to the 2020 third quarter. 2021 third quarter revenues and operating income were also impacted by Hurricane Ida which shuttered almost the entire Southeast Louisiana refinery and chemical complex and key waterways for an extended period of time. The 2021 first nine months was also heavily impacted by Winter Storm Uri during the first quarter which shut down many Gulf Coast refineries and chemical plants for an extended period of time starting in mid-February. These emergency shutdowns resulted in significantly reduced liquids production and lower volumes for the Company’s inland marine transportation market during the 2021 first quarter. The 2021 and 2020 first quarters were also impacted by poor operating conditions including seasonal wind and fog along the Gulf Coast, flooding on the Mississippi River, and various lock closures along the Gulf Intracoastal Waterway, in addition to ice on the Illinois River during the 2021 first quarter and increased shipyard days on large capacity coastal vessels during the 2020 first quarter. For the 2021 third quarter and first nine months, the inland tank barge fleet contributed 76% and 75%, respectively, and the coastal fleet contributed 24% and 25%, respectively, of marine transportation revenues. For the 2020 third quarter and first nine months, the inland tank barge fleet contributed 77% and 79%, respectively, and the coastal fleet contributed 23% and 21%, respectively, of marine transportation revenues.

Inland tank barge utilization levels averaged in the mid-70% range during the 2021 first quarter, the low to mid-80% range during the 2021 second quarter, and the low 80% range during the 2021 third quarter. In 2020, inland tank barge utilization levels averaged in the low to mid-90% range during the 2020 first quarter, the mid-80% range during the 2020 second quarter, and the low 70% range during the 2020 third quarter. The 2021 first nine months and the 2020 second and third quarters were impacted by reduced demand as a result of the COVID-19 pandemic and the resulting economic slowdown. The 2021 second quarter was favorably impacted by the Colonial Pipeline outage in May. The 2021 first nine months was also impacted by reduced volumes as a result of Winter Storm Uri during the first quarter. The 2020 first quarter experienced strong demand from petrochemicals, black oil, and refined petroleum products customers. In addition, extensive delay days due to poor operating conditions and lock maintenance projects in the 2020 first quarter slowed the transport of customer cargoes and contributed to strong utilization.

Coastal tank barge utilization levels averaged in the mid-70% range during the 2021 first and third quarters and the low to mid‑70% range during the 2021 second quarter. Coastal tank barge utilization levels averaged in the low to mid-80% range during the 2020 first quarter and the mid-70% range during the 2020 second and third quarters. The 2021 first nine months and the 2020 second and third quarters were impacted by reduced demand as a result of the COVID-19 pandemic and the resulting economic slowdown. Barge utilization in the coastal marine fleet continued to be impacted by the oversupply of tank barges in the coastal industry in 2021 and 2020.

During both the 2021 third quarter and first nine months, approximately 65% of marine transportation’s inland revenues were under term contracts and 35% were spot contract revenues. During the 2020 third quarter and first nine months, approximately 70% and 65%, respectively, of marine transportation’s inland revenues were under term contracts and 30% and 35%, respectively, were spot contract revenues. Inland time charters during the 2021 third quarter and first nine months represented 56% and 58%, respectively, of the inland revenues under term contracts compared with 67% in both the 2020 third quarter and first nine months. During both the 2021 third quarter and first nine months, approximately 80% of the coastal revenues were under term contracts and 20% were spot contract revenues. During both the 2020 third quarter and first nine months, approximately 85% of coastal revenues were under term contracts, and 15% were under spot contract revenues. Coastal time charters represented approximately 85% of coastal revenues under term contracts during both the 2021 third quarter and first nine months compared with approximately 90% during both the 2020 third quarter and first nine months. Term contracts have contract terms of 12 months or longer, while spot contracts have contract terms of less than 12 months.

(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, 2021, 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 3%, excluding fuel.

The marine transportation segment operating margin was 5.0% for the 2021 third quarter compared with 10.1% for the 2020 third quarter and 3.8% for the 2021 first nine months compared to 12.2% for the 2020 first nine months.

Distribution and Services

The Company, through its distribution and services segment, 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 and other industrial applications. The Company also rents equipment including generators, industrial compressors, railcar movers, and high capacity lift trucks for use in a variety of industrial markets, and manufactures and remanufactures oilfield service equipment, including pressure pumping units, for land-based oilfield service customers.

For the 2021 third quarter and first nine months, the distribution and services segment generated 43% and 41%, respectively, of the Company’s revenues, of which 87% and 86%, respectively, was generated from service and parts and 13% and 14%, respectively, from manufacturing. The results of the distribution and services segment are largely influenced by the economic cycles of the oilfield service and oil and gas operator and producer markets, marine, power generation, on-highway, and other industrial markets.

Distribution and services revenues for the 2021 third quarter and first nine months increased 48% and 18%, respectively, and operating income increased 900% and 316%, respectively, compared with the 2020 third quarter and first nine months revenues and operating income. In the commercial and industrial market, the increases in the 2021 third quarter and first nine months compared to the 2020 third quarter and first nine months were primarily attributable to improved economic activity across the U.S. which resulted in higher business levels in the power generation and on-highway businesses. Increased product sales in Thermo King also contributed favorably to the 2021 third quarter and first nine months results. The marine repair business was down slightly compared to the 2020 third quarter and first nine months due to reduced service activity. The commercial and industrial market 2021 first nine months was impacted by Winter Storm Uri with reduced activity levels at many locations across the Southern U.S. during the first quarter. For the 2021 third quarter and first nine months, the commercial and industrial market contributed 59% and 63%, respectively, of the distribution and services revenues.

In the oil and gas market, revenues improved compared to the 2020 third quarter and first nine months due to higher oilfield activity which resulted in increased demand for new and overhauled engines, transmissions, parts, and service. The manufacturing business also experienced increases in orders and deliveries of new and remanufactured pressure pumping equipment as well as power generation equipment for electric fracturing. For the 2021 third quarter and first nine months, the oil and gas market contributed 41% and 37%, respectively, of the distribution and services revenues.

The distribution and services segment operating margin for the 2021 third quarter was 4.2% compared with 0.6% for the 2020 third quarter and 2.9% for the 2021 first nine months compared to (1.6)% for the 2020 first nine months. The 2020 first nine months results were adversely impacted by the bankruptcy of a large oil and gas customer, resulting in a $3,339,000 bad debt expense charge and severance expenses of $1,354,000 as a result of workforce reductions.

Outlook

Although the COVID-19 delta variant in the U.S. and around the world has created some uncertainty which has slowed the pace of the economic recovery, the Company expects further growth in marine transportation during the 2021 fourth quarter. Supply chain and labor constraints and delays of key components, particularly in distribution and services, could defer some product sales and manufacturing deliveries into 2022 resulting in modest declines in revenue in distribution and services during the 2021 fourth quarter.

In the inland marine transportation market, barge utilization in October improved into the high 80% range and is expected to remain strong for the duration of the fourth quarter as Louisiana refinery and petrochemical plants restart and customers boost production levels to meet pend-up demand. While ongoing navigational issues in the wake of Hurricane Ida, which have resulted in extended closures of key waterways and contributed to some increases in barge utilization, should subside, the onset of seasonal winter weather and continued economic growth should result in improved barge utilization. Overall, increased inland activity levels should yield further improvements in the spot market, which currently represents approximately 35% of inland revenue, and contribute to improved revenues and operating margins. During the fourth quarter and into 2022, term contracts that renewed lower over the past year should reset to reflect the improved market conditions. Overall, inland revenues are expected to increase in the 2021 fourth quarter with operating margins around 10%.

As of September 30, 2021, the Company estimated there were approximately 4,000 inland tank barges in the industry fleet, of which approximately 350 were over 30 years old and approximately 285 of those over 40 years old. The Company estimates that approximately 60 to 75 new tank barges have been ordered for delivery in 2021 and many older tank barges, including an expected 28 by the Company, will be retired, dependent on 2021 market conditions. Historically, 75 to 150 older inland tank barges are retired from service each year industry-wide. The extent of the retirements is dependent on petrochemical and refinery production levels, and crude oil and natural gas condensate movements, both of which can have a direct effect on industry-wide tank barge utilization, as well as term and spot contract rates.

In the coastal marine transportation market, market conditions are expected to modestly improve in the 2021 fourth quarter. Combined with the recent sale of the Hawaiian marine equipment and the retirement of underutilized barges, coastal barge utilization is expected to be near 90% in the fourth quarter. Although the Hawaii equipment has been sold, the Company has chartered and will continue to operate the assets until existing customer contracts expire at the end of 2021. Elsewhere in the coastal market, planned shipyard activity on several large capacity barges will likely result in an overall sequential revenue reduction in the mid-single digits during the fourth quarter with operating margins at or slightly below breakeven.

As of September 30, 2021, the Company estimated there were approximately 270 tank barges operating in the 195,000 barrels or less coastal industry fleet, the sector of the market in which the Company operates, and approximately 20 of those were over 25 years old. The Company is aware of one announced small specialized coastal ATB in the 195,000 barrels or less category that was delivered in the 2021 first quarter with no further coastal barges currently under construction.

The results of the distribution and services segment are largely influenced by the cycles of the land-based oilfield service and oil and gas operator and producer markets, marine, power generation, on-highway and other industrial markets. Seasonality in the commercial and industrial market, including reduced marine repair activity, lower demand for Thermo King refrigeration parts and service, and reduced utilization of the power generation rental fleet, are all expected to contribute to sequential reductions in revenue and operating income in the 2021 fourth quarter.

In the distribution and services oil and gas market, strong commodity prices and oilfield activity levels are expected to yield robust demand for new transmissions, service, and parts for the duration of the year. In manufacturing, activity is also expected to remain strong driven by an increasing backlog of environmentally friendly pressure pumping equipment, frac related power generation equipment, and remanufacturing of existing conventional equipment. However, increasing original equipment manufacturer supply chain issues are expected to delay some sales into 2022 and result in a sequential reduction in oil and gas revenues and operating margins. Overall, compared to the 2021 third quarter, distribution and services revenues are expected to decline modestly with operating margins in the low to mid-single digits.

While the Company's outlook is dependent on developments regarding the COVID-19 pandemic and related supply chain constraints, the Company has maintained business continuity and expects to continue to do so.

Acquisition

During the nine months ended September 30, 2021, the Company purchased four inland tank barges from a leasing company for $7,470,000 in cash. The Company had been leasing the barges prior to the purchase. Financing of the purchase was through cash provided by operating activities.

The Company’s marine transportation segment’s revenues for the 2021 third quarter and first nine months increased 6% and decreased 12%, respectively, compared with the 2020 third quarter and first nine months revenues. The increase for the 2021 third quarter was primarily due to increased fuel rebills in the inland and coastal markets and increased tank barge utilization in the inland market. The decrease for the 2021 first nine months was primarily due to reduced barge utilization in the inland and coastal markets as well as reduced term and spot pricing in the inland market when compared to 2020. The decrease was partially offset by the addition of the Savage fleet acquired on April 1, 2020. The 2021 third quarter benefited from improving business activity and inland market barge utilization which were largely offset by reduced term pricing when compared to the 2020 third quarter. 2021 third quarter revenues and operating income were also impacted by Hurricane Ida which shuttered almost the entire Southeast Louisiana refinery and chemical complex and key waterways for an extended period of time. The 2021 first nine months was also heavily impacted by Winter Storm Uri during the first quarter which shut down many Gulf Coast refineries and chemical plants for an extended period of time starting in mid-February. These emergency shutdowns resulted in significantly reduced liquids production and lower volumes for the Company’s inland marine transportation market during the 2021 first quarter. The 2021 and 2020 first quarters were also impacted by poor operating conditions including seasonal wind and fog along the Gulf Coast, flooding on the Mississippi River, and various lock closures along the Gulf Intracoastal Waterway, in addition to ice on the Illinois River during the 2021 first quarter and increased shipyard days on large capacity coastal vessels during the 2020 first quarter. For the 2021 third quarter and first nine months, the inland tank barge fleet contributed 76% and 75%, respectively, and the coastal fleet contributed 24% and 25%, respectively, of marine transportation revenues. For the 2020 third quarter and first nine months, the inland tank barge fleet contributed 77% and 79%, respectively, and the coastal fleet contributed 23% and 21%, respectively, of marine transportation revenues.

Inland tank barge utilization levels averaged in the mid-70% range during the 2021 first quarter, the low to mid-80% range during the 2021 second quarter, and the low 80% range during the 2021 third quarter. In 2020, inland tank barge utilization levels averaged in the low to mid-90% range during the 2020 first quarter, the mid-80% range during the 2020 second quarter, and the low 70% range during the 2020 third quarter. The 2021 first nine months and the 2020 second and third quarters were impacted by reduced demand as a result of the COVID-19 pandemic and the resulting economic slowdown. The 2021 second quarter was favorably impacted by the Colonial Pipeline outage in May. The 2021 first nine months was also impacted by reduced volumes as a result of Winter Storm Uri during the first quarter. The 2020 first quarter experienced strong demand from petrochemicals, black oil, and refined petroleum products customers. In addition, extensive delay days due to poor operating conditions and lock maintenance projects in the 2020 first quarter slowed the transport of customer cargoes and contributed to strong utilization.

Coastal tank barge utilization levels averaged in the mid-70% range during the 2021 first and third quarters and the low to mid‑70% range during the 2021 second quarter. Coastal tank barge utilization levels averaged in the low to mid-80% range during the 2020 first quarter and the mid-70% range during the 2020 second and third quarters. The 2021 first nine months and the 2020 second and third quarters were impacted by reduced demand as a result of the COVID-19 pandemic and the resulting economic slowdown. Barge utilization in the coastal marine fleet continued to be impacted by the oversupply of tank barges in the coastal industry in 2021 and 2020.

The petrochemical market, the Company’s largest market, contributed 51% and 50% of marine transportation revenues for the 2021 third quarter and first nine months, respectively, reflecting reduced volumes from Gulf Coast petrochemical plants for both domestic consumption and to terminals for export destinations as a result of the COVID-19 pandemic. During the 2021 first quarter, as much as 80% of U.S. chemical plant capacity was offline at the peak of Winter Storm Uri, contributing to significantly reduced volumes and revenues; however, volumes and revenues sequentially improved in the 2021 second quarter as chemical plants resumed full operations by May. During the 2021 third quarter, volumes declined again as numerous Louisiana chemical plants were shut down for an extended period of time as a result of Hurricane Ida.

The black oil market, which contributed 25% and 26% of marine transportation revenues for the 2021 third quarter and first nine months, respectively, reflected reduced demand as refinery production levels and the export of refined petroleum products and fuel oils declined as a result of the COVID-19 pandemic. During the 2021 first quarter, U.S. refinery utilization dropped to near 40% during the peak of Winter Storm Uri, contributing to significantly reduced volumes and revenues. Although refinery utilization increased back to near 90% in the 2021 second quarter contributing to sequentially increased volumes and revenues, volumes declined again during the 2021 third quarter as Louisiana refineries were shut down for an extended period of time as a result of Hurricane Ida. During the 2021 third quarter and first nine months, the Company continued to transport crude oil and natural gas condensate produced from the Permian Basin as well as reduced volumes from the Eagle Ford shale formation in Texas, both 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 and Canadian and Bakken crude downriver from the Midwest to the Gulf Coast.

23

The refined petroleum products market, which contributed 20% of marine transportation revenues for both the 2021 third quarter and first nine months, reflected lower volumes in both the inland and coastal markets as a result of reduced demand related to the COVID-19 pandemic. In addition, during the 2021 first quarter, U.S. refinery utilization dropped to near 40% during the peak of Winter Storm Uri, contributing to significantly reduced volumes and revenues. Although refinery utilization increased back to near 90% in the 2021 second quarter contributing to sequentially increased volumes and revenues, volumes declined again during the 2021 third quarter as Louisiana refineries were shut down for an extended period of time as a result of Hurricane Ida.

The agricultural chemical market, which contributed 4% of marine transportation revenues for both the 2021 third quarter and first nine months, saw modest reductions in demand for transportation of both domestically produced and imported products, primarily due to reduced demand associated with the COVID-19 pandemic.

For the 2021 third quarter, the inland operations incurred 1,499 delay days, 12% more than the 1,335 delay days that occurred during the 2020 third quarter. For the 2021 first nine months, the inland operations incurred 7,275 delay days, 16% fewer than the 8,640 delay days that occurred during the 2020 first nine 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 for the 2021 and 2020 first nine months reflected poor operating conditions due to heavy wind and fog along the Gulf Coast, high water conditions on the Mississippi River System, and closures of key waterways as a result of lock maintenance projects during the 2021 and 2020 first quarters. The decrease in delay days in the 2021 first nine months reflects reduced volumes and barge utilization compared to the 2020 first nine months while the increase in delay days in the 2021 third quarter reflects the impacts of Hurricane Ida as well as significant lock closures along the Gulf Intracoastal Waterway compared to the 2020 third quarter.

During both the 2021 third quarter and first nine months, approximately 65% of marine transportation’s inland revenues were under term contracts and 35% were spot contract revenues. During the 2020 third quarter and first nine months, approximately 70% and 65%, respectively, of marine transportation’s inland revenues were under term contracts and 30% and 35%, respectively, were spot contract revenues. Inland time charters during the 2021 third quarter and first nine months represented 56% and 58%, respectively, of the inland revenues under term contracts compared with 67% in both the 2020 third quarter and first nine months. During both the 2021 third quarter and first nine months, approximately 80% of the coastal revenues were under term contracts and 20% were spot contract revenues. During both the 2020 third quarter and first nine months, approximately 85% of coastal revenues were under term contracts, and 15% were under spot contract revenues. Coastal time charters represented approximately 85% of coastal revenues under term contracts during both the 2021 third quarter and first nine months compared with approximately 90% during both the 2020 third quarter and first nine months.

The following table summarizes the average range of pricing changes in term and spot contracts renewed during 2021 compared to contracts renewed during the corresponding quarter of 2020:

(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, 2021, 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 3%, excluding fuel.

Marine Transportation Costs and Expenses

Costs and expenses for the 2021 third quarter and first nine months increased 12% and decreased 4%, respectively, compared with the 2020 third quarter and first nine months. Costs of sales and operating expenses for the 2021 third quarter and first nine months increased 15% and decreased 5%, respectively, compared with the 2020 third quarter and first nine months, respectively. The decreases during the 2021 first nine months primarily reflect to cost reductions across the segment, including a reduction in towboats during the 2020 last nine months and the 2021 first quarter and a reduction in maintenance expenses during the first half of the year, partially offset by the addition of the Savage fleet in April 2020. The increases during the 2021 third quarter primarily reflect increased fuel costs and maintenance expenses as business activity levels improved.

24

The inland marine transportation fleet operated an average of 243 towboats during the 2021 third quarter, of which an average of 30 were chartered, compared with 265 during the 2020 third quarter, of which an average of 36 were chartered. The decrease was primarily due to reduced horsepower requirements as a result of a smaller barge fleet, crewing issues associated with the COVID-19 delta variant, and reduced activity as a result of the impacts of Hurricane Ida. Generally, as demand or anticipated demand increases or decreases, as new tank barges are added to or removed from the fleet, as chartered towboat availability changes, or as weather or water conditions dictate, the Company charters in or releases chartered towboats in an effort to balance horsepower needs with current requirements. The Company has historically used chartered towboats for approximately one-fourth of its horsepower requirements.

During the 2021 third quarter, the inland operations consumed 11.8 million gallons of diesel fuel compared to 10.2 million gallons consumed during the 2020 third quarter. The average price per gallon of diesel fuel consumed during the 2021 third quarter was $2.24 per gallon compared with $1.27 per gallon for the 2020 third quarter. During the 2021 first nine months, the inland operations consumed 34.4 million gallons of diesel fuel compared to 36.3 million gallons consumed during the 2020 first nine months. The average price per gallon of diesel fuel consumed during the 2021 first nine months was $1.99 per gallon compared with $1.47 per gallon for the 2020 first nine months. Fuel escalation and de-escalation clauses on term contracts 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 90 day delay before contracts are adjusted. Spot contracts do not have escalators for fuel.

Selling, general and administrative expenses for the 2021 third quarter and first nine months increased 11% and 4%, respectively, compared with the 2020 third quarter and first nine months. The increase in the 2021 third quarter was primarily due to higher incentive compensation accruals, medical costs, and professional fees.

Taxes, other than on income, for the 2021 third quarter and first nine months increased 15% and decreased 14%, respectively, compared with the 2020 third quarter and first nine months. The increase during the 2021 third quarter primarily reflected higher property taxes on marine transportation equipment due to a favorable adjustment in the 2020 third quarter and higher waterway use taxes, while the decrease for the first nine months reflected lower property taxes on marine transportation equipment during the first half of the year.

Depreciation and amortization for the 2021 third quarter and first nine months decreased 2% and increased 2%, respectively, compared to the 2020 third quarter and first nine months. The decrease in the 2021 third quarter primarily reflects retirements of marine equipment during the 2020 fourth quarter and the 2021 first nine months while the increase in the first nine months reflects the acquisition of the Savage fleet in April 2020.

Marine Transportation Operating Income and Operating Margin

Marine transportation operating income for the 2021 third quarter and first nine months decreased 48% and 72%, respectively, compared with the 2020 third quarter and first nine months. The 2021 third quarter operating margin was 5.0% compared with 10.1% for the 2020 third quarter. The 2021 first nine months operating margin was 3.8% compared with 12.2% for the 2020 first nine months. The decreases in operating income and operating margin were primarily due to reduced barge utilization in the inland and coastal markets as well as decreased term and spot contract pricing in the inland market, each as a result of a reduction in demand due to the COVID-19 pandemic and reduced volumes as a result of Hurricane Ida and Winter Storm Uri along with increased maintenance costs during the 2021 third quarter. Operating margins for the 2021 third quarter and first nine months were also impacted by the increased cost of diesel fuel.

Distribution and Services Revenues

The following table shows the markets serviced by the Company’s distribution and services segment, the revenue distribution, and the customers for each market:

Markets Serviced |  | 2021 Third Quarter Revenue Distribution |  | 2021 Nine Months Revenue Distribution |  | Customers
Commercial and Industrial |  | 59% |  | 63% |  | Inland River Carriers — Dry and Liquid, Offshore Towing — Dry and Liquid, Offshore Oilfield Services — Drilling Rigs & Supply Boats, Harbor Towing, Dredging, Great Lakes Ore Carriers, Pleasure Crafts, On and Off-Highway Transportation, Power Generation, Standby Power Generation, Pumping Stations, Mining
Oil and Gas |  | 41% |  | 37% |  | Oilfield Services, Oil and Gas Operators and Producers

Distribution and services revenues for the 2021 third quarter and first nine months increased 48% and 18%, respectively, compared with the 2020 third quarter and first nine months revenues. In the commercial and industrial market, the increase in the 2021 third quarter and first nine months compared to the 2020 third quarter and first nine months was primarily attributable to improved economic activity across the U.S. which resulted in higher business levels in the power generation and on-highway businesses. Increased product sales in Thermo King also contributed favorably to the 2021 third quarter and first nine months results. The marine repair business was down slightly compared to the 2020 third quarter and first nine months due to reduced service activity. The commercial and industrial market 2021 first nine months was impacted by Winter Storm Uri with reduced activity levels at many locations across the Southern U.S. during the first quarter. For the 2021 third quarter and first nine months, the commercial and industrial market contributed 59% and 63%, respectively, of the distribution and services revenues.

In the oil and gas market, revenues improved compared to the 2020 third quarter and first nine months due to higher oilfield activity which resulted in increased demand for new and overhauled engines, transmissions, parts, and service. The manufacturing business also experienced increases in orders and deliveries of new and remanufactured pressure pumping equipment as well as power generation equipment for electric fracturing. For the 2021 third quarter and first nine months, the oil and gas market contributed 41% and 37%, respectively, of the distribution and services revenues.

26

Distribution and Services Costs and Expenses

Costs and expenses for the 2021 third quarter and first nine months increased 43% and 13%, respectively, compared with the 2020 third quarter and first nine months. Costs of sales and operating expenses for the 2021 third quarter and first nine months increased 55% and 19%, respectively, compared with the 2020 third quarter and first nine months, reflecting higher demand in the on-highway and power generation businesses in commercial and industrial markets in the 2021 third quarter. The increase also reflects higher demand for new and overhauled transmissions and related parts and service and increased demand for new pressure pumping equipment in the oil and gas market.

Selling, general and administrative expenses for the 2021 third quarter and first nine months increased 6% and decreased 4%, respectively, compared to the 2020 third quarter and first nine months. The increase for the 2021 third quarter is primarily due to increased incentive compensation accruals, medical costs, and warranty accruals, while the decrease for the first nine months was primarily due to a bad debt expense charge of $3,339,000 as a result of the bankruptcy of a large oil and gas customer and $1,354,000 of severance expense as a result of workforce reductions each during the 2020 second quarter.

Depreciation and amortization for the 2021 third quarter and first nine months decreased 20% and 25%, respectively, compared to the 2020 third quarter and first nine months. The decrease during the 2021 first nine months was primarily due to lower amortization of intangible assets other than goodwill, which were impaired during the 2020 first quarter. The decrease during the 2021 third quarter also reflected certain equipment and leasehold improvements acquired from Stewart & Stevenson LLC becoming fully depreciated during 2020.

Distribution and Services Operating Income (Loss) and Operating Margin

Operating income for the distribution and services segment for the 2021 third quarter and first nine months increased 900% and 316%, respectively, compared with the 2020 third quarter and first nine months. The operating margin for the 2021 third quarter was 4.2% compared with 0.6% for the 2020 third quarter and 2.9% for the 2021 first nine months compared to (1.6)% for the 2020 first nine months. The results reflect increased business levels in both the commercial and industrial and oil and gas markets and a return to profitability, partially offset by higher costs and expenses.

General Corporate Expenses

General corporate expenses for the 2021 third quarter and first nine months increased compared to the 2020 third quarter and first nine months primarily due to costs related to Hurricane Ida.

(Gain) Loss on Disposition of Assets

The Company reported a net gain on disposition of assets of $830,000 for the 2021 third quarter compared with a net loss of $316,000 for the 2020 third quarter.

Average interest rate |  |  | 3.3 | % |  |  | 2.9 | % |  |  | 3.2 | % |  |  | 3.1 | %

Interest expense for the 2021 third quarter and first nine months decreased 11% and 14%, respectively, compared with the 2020 third quarter and first nine months, primarily due to a lower average debt outstanding as a result of debt repayments since the 2020 first quarter. There was no capitalized interest excluded from interest expense during the 2021 or 2020 first nine months.

Benefit for Taxes on Income

During the 2020 third quarter and first nine months, pursuant to provisions of the CARES Act, net operating losses generated during 2018 through 2020 were used to offset taxable income generated between 2013 through 2017. Net operating losses carried back to tax years 2013 through 2017 were applied at the higher federal statutory tax rate of 35% compared to the statutory rate of 21% in effect at September 30, 2020. The Company generated an effective tax rate benefit in the 2020 third quarter and first nine months as a result of such carrybacks.

The decrease reflected $157,607,000 of depreciation expense, $131,773,000 of property disposals, including the sale of the Hawaii marine transportation equipment, and retirement of underutilized equipment that was reclassified to held for sale, and $15,430,000 of non-cash impairment charges related to coastal marine transportation equipment held and used during the 2021 first nine months, partially offset by $85,517,000 of capital additions (including an increase in accrued capital expenditures of $13,549,000) and $7,470,000 related to the acquisition of four inland tank barges during the 2021 first nine months, more fully described under Cash Flows and Capital Expenditures below.

Operating lease right-of-use assets as of September 30, 2021 decreased 8% compared to December 31, 2020, primarily due to lease amortization expense and impairment charges, partially offset by new leases acquired during the 2021 first nine months.

Goodwill, as of September 30, 2021 decreased 33% compared with December 31, 2020, due to a goodwill impairment in the marine transportation segment.

Other intangibles, net, as of September 30, 2021 decreased 10% compared with December 31, 2020, primarily due to amortization during the 2021 first nine months.

Other assets as of September 30, 2021 decreased 22% compared with December 31, 2020, primarily due to amortization of drydock expenditures during the 2021 first nine months.

Current liabilities as of September 30, 2021 increased 10% compared with December 31, 2020. Accounts payable increased 12%, primarily due to an increase in accrued capital expenditures.

Operating lease liabilities – less current portion, as of September 30, 2021 decreased 7% compared to December 31, 2020, primarily due to lease payments made, partially offset by new leases acquired and liability accretion during the 2021 first nine months.

Other long-term liabilities as of September 30, 2021 decreased 9% compared with December 31, 2020, primarily due to amortization of intangible liabilities and a decrease in pension liabilities.

Total equity as of September 30, 2021 decreased 8% compared with December 31, 2020. The decrease was primarily due to the net loss attributable to Kirby of $257,915,000 and tax withholdings of $2,856,000 on restricted stock and RSU vestings, partially offset by amortization of unearned share-based compensation of $12,793,000, each during the 2021 first nine months.

Cash Flow and Capital Expenditures

The Company generated favorable operating cash flows during the 2021 first nine months with net cash provided by operating activities of $280,362,000 compared with $359,763,000 for the 2020 first nine months, a 22% decrease. The decrease was primarily due to decreased revenues and operating income in the marine transportation segment, partially offset by the receipt of a tax refund of $119,493,000, including accrued interest, for the Company’s 2019 federal tax return, increased revenues and operating income in the distribution and services segment, reduced incentive compensation payouts in the 2021 first quarter compared to the 2020 first quarter, and the Savage acquisition in April 2020. Decreases in marine transportation revenues and operating income were driven by reduced barge utilization in the inland and coastal markets during the first half of 2021 and decreased term and spot contract pricing in the inland market, each as a result of a reduction in demand due to the COVID-19 pandemic. The 2021 third quarter marine transportation revenues and operating income were also negatively impacted by the impacts of Hurricane Ida. The decrease in cash flows was also partially due to a smaller decrease in inventories in the 2021 first nine months than in the 2020 first nine months. During the 2021 and 2020 first nine months, the Company generated cash of $39,163,000 and $6,538,000, respectively, from proceeds from the disposition of assets, including the sale of the Hawaii marine transportation equipment in the 2021 third quarter, and $629,000 and $353,000, respectively, from proceeds from the exercise of stock options.

For the 2021 first nine months, cash generated was used for capital expenditures of $71,968,000 (net of an increase in accrued capital expenditures of $13,549,000), including $5,151,000 for inland towboat construction and $66,817,000 primarily for upgrading existing marine equipment and marine transportation and distribution and services facilities.

Treasury Stock Purchases

The Company did not purchase any treasury stock during the 2021 first nine months. As of November 5, 2021, the Company had approximately 1,400,000 shares available under its existing repurchase authorization. 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.

Liquidity

Funds generated from operations are available for acquisitions, capital expenditure projects, common stock repurchases, repayments of borrowings, and for other corporate and operating requirements. In addition to net cash flows provided by operating activities, as of November 5, 2021 the Company also had cash equivalents of $39,277,000, availability of $844,937,000 under its Revolving Credit Facility, and $8,701,000 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 the pricing grid on its Credit Agreement.

The Company expects to continue to fund expenditures for acquisitions, capital construction projects, common stock repurchases, 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 Revolving Credit Facility’s commitment is in the amount of $850,000,000 and expires March 27, 2024. As of September 30, 2021, the Company had $844,937,000 available under the Revolving Credit Facility. The 3.29% senior unsecured notes do not mature until February 27, 2023 and require no prepayments. The 4.2% senior unsecured notes do not mature until March 1, 2028 and require no prepayments. The Term Loan is due on March 27, 2024 and is prepayable, in whole or in part, without penalty.

There are numerous factors that may negatively impact the Company’s cash flows in 2021. For a list of significant risks and uncertainties that could impact cash flows, see Note 14, Contingencies and Commitments, in the financial statements, 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, 2020. 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 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

31

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 $21,199,000 at September 30, 2021, including $13,847,000 in letters of credit and $7,352,000 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.

All marine transportation term contracts contain fuel escalation clauses, or the customer pays for the fuel. However, there is generally a 30 to 90 day delay before contracts are adjusted depending on the specific 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. Spot contract rates generally reflect current fuel prices at the time the contract is signed but do not have escalators for fuel.

While inflationary pressures have increased in 2021, 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 which generally contain cost escalation clauses whereby certain costs, including fuel as noted above, can be passed through to its customers. Spot contract rates include the cost of fuel and are subject to market volatility. In the distribution and services segment, the cost of major components for large manufacturing orders is secured with suppliers at the time a customer order is finalized, which limits exposure to inflation. The repair portion of the distribution and services segment is based on prevailing current market rates.

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 1% increase in variable interest rates would impact the 2021 interest expense by $6,250,000 based on balances outstanding at December 31, 2020, and would change the fair value of the Company’s debt by approximately 3%.

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 September 30, 2021, 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 September 30, 2021, 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. During the third quarter of 2021, the Company completed the preparation and implementation of changes to its financial reporting software. There were no other changes in the Company’s internal control over financial reporting during the quarter ended September 30, 2021 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
