OLD DOMINION FREIGHT LINE INC

Previous wording

LTL Revenue Per Hundredweight - Our LTL transportation services are generally priced based on weight, commodity, and distance. This measurement reflects the application of our pricing policies to the services we provide, which are influenced by competitive market conditions and our growth objectives. Generally, freight is rated by a class system, which is established by the National Motor Freight Traffic Association, Inc. Light, bulky freight typically has a higher class and is priced at higher revenue per hundredweight than dense, heavy freight. Fuel surcharges, accessorial charges, revenue adjustments and revenue for undelivered freight are included in this measurement. Revenue for undelivered freight is deferred for financial statement purposes in accordance with our revenue recognition policy; however, we believe including it in our revenue per hundredweight metrics results in a more accurate representation of the underlying changes in our yields by matching total billed revenue with the corresponding weight of those shipments.

Fuel surcharges, accessorial charges, revenue adjustments and revenue for undelivered freight are included in this measurement, and we regularly monitor the components that impact our pricing. The fuel surcharge is generally designed to offset fluctuations in the cost of our petroleum-based products and is indexed to diesel fuel prices published by the U.S. Department of Energy, which reset each week.

Previous wording

Our primary revenue focus is to increase density, which is shipment and tonnage growth within our existing infrastructure. Increases in density allow us to maximize our asset utilization and labor productivity, which we measure over many different functional areas of our operations including linehaul load factor, P&D stops per hour, P&D shipments per hour, platform pounds handled per hour and platform shipments per hour. In addition to our focus on density and operating efficiencies, it is critical for us to obtain an appropriate yield, which is measured as revenue per hundredweight, on the shipments we handle to offset our cost inflation and support our ongoing investments in capacity and technology. We regularly monitor the components of our pricing, including base freight rates, accessorial charges and fuel surcharges. The fuel surcharge is generally designed to offset fluctuations in the cost of our petroleum-based products and is indexed to diesel fuel prices published by the U.S. Department of Energy, which reset each week. We believe our yield management process appropriately focuses on individual account profitability, and ongoing improvements in operating efficiencies, as key components of our ability to produce profitable growth.

Current wording

Our primary revenue focus is to increase density, which is shipment and tonnage growth within our existing infrastructure. Increases in density allow us to maximize our asset utilization and labor productivity, which we measure over many different functional areas of our operations including linehaul load factor, pickup and delivery (“P&D”) stops per hour, P&D shipments per hour, platform pounds handled per hour and platform shipments per hour. In addition to our focus on density and operating efficiencies, it is critical for us to obtain an appropriate yield, which is measured as revenue per hundredweight, on the shipments we handle. We focus on the profitability of each customer account and generally seek to obtain an appropriate yield to offset our cost inflation and support our ongoing investments in capacity and technology. We believe the continued execution of this yield-management philosophy, continued increases in density, and ongoing improvements in operating efficiencies are the key components of our ability to further improve our operating ratio and long-term profitable growth.

Previous wording

Our financial results for 2023 reflect continued softness in the domestic economy that contributed to the decline in our revenue. Despite the decrease in our LTL tons, we maintained a commitment to providing superior customer service to support the continued improvement in our yield. We continued to focus on controlling our costs in the low volume environment, but we continued to invest in new capacity in anticipation of long-term growth in our market share. As a result, our depreciation costs increased as a percent of revenue and contributed to the slight increase in our operating ratio to 72.0% for 2023. In addition, our net income and diluted earnings per share decreased by 10.0% and 7.6%, respectively, as compared to 2022.

Current wording

Our financial results for 2024 reflect continued softness in the domestic economy that contributed to the decline in our revenue. Despite the decrease in our LTL tons, we maintained a commitment to providing superior customer service to support the continued improvement in our yield as we provided our customers with 99% on-time service and a cargo claims ratio of 0.1% during the year. We maintained our focus on operating efficiently and controlling discretionary spending during the year, but the increase in costs and the deleveraging effect from the decrease in revenue led to an increase in our operating ratio. As a result, our net income and diluted earnings per share decreased by 4.3% and 2.7%, respectively, as compared to 2023.

Previous wording

Revenue decreased $393.9 million, or 6.3%, in 2023 compared to 2022. This decrease resulted from a 9.0% decrease in LTL tonnage per day, which was primarily due to decreases in LTL shipments per day and LTL weight per shipment. This decrease in revenue was partially offset by a 3.5% increase in our LTL revenue per hundredweight. Our LTL revenue per hundredweight includes the impact of lower fuel surcharges resulting from a decline in the average price of diesel fuel for the comparable periods. Excluding fuel surcharges, LTL revenue per hundredweight increased 8.3% in 2023 as compared to 2022. We believe the increase in our LTL revenue-per-hundredweight metrics was driven by the ongoing execution of our yield management strategy, which is focused on obtaining price increases necessary to offset our cost inflation and support our continued investments in capacity and technology.

Current wording

Revenue decreased $51.3 million, or 0.9%, in 2024 compared to 2023 due to a decrease in volumes that was partially offset by an increase in LTL revenue per hundredweight. LTL tonnage per day decreased 3.6% primarily due to decreases in LTL shipments per day and LTL weight per shipment. This decrease in our volumes was partially offset by a 2.4% increase in our LTL revenue per hundredweight. Our LTL revenue per hundredweight includes the impact of lower fuel surcharges resulting from a decline in the average price of diesel fuel from the comparable period. Excluding fuel surcharges, LTL revenue per hundredweight increased 5.0% in 2024 as compared to 2023. We believe the increase in our LTL revenue-per-hundredweight metrics was driven by the ongoing execution of our yield management strategy. Our consistent, cost-based approach to pricing focuses on offsetting our cost inflation while also supporting additional investments into our business to expand capacity and enhance our technology.

Previous wording

Revenue per day decreased 2.7% in January 2024 compared to the same month last year. LTL tons per day decreased 5.0%, due primarily to a 2.3% decrease in LTL shipments per day and a 2.8% decrease in LTL weight per shipment. LTL revenue per hundredweight increased 2.7% as compared to the same month last year. LTL revenue per hundredweight, excluding fuel surcharges, increased 6.7% as compared to the same month last year.

Current wording

Revenue per day decreased 4.2% in January 2025 compared to the same month last year. LTL tons per day decreased 7.1%, due primarily to a 5.4% decrease in LTL shipments per day and a 1.7% decrease in LTL weight per shipment. LTL revenue per hundredweight increased 3.1% as compared to the same month last year. LTL revenue per hundredweight, excluding fuel surcharges, increased 4.5% as compared to the same month last year.

Previous wording

Salaries, wages, and benefits decreased $87.2 million, or 3.2%, in 2023 as compared to 2022, due to an $83.1 million decrease in the costs attributable to salaries and wages and a $4.1 million decrease in employee benefit costs. The decrease in salaries and wages was due primarily to decreases in the average number of active full-time employees during the year, as we balanced our workforce to align with our customers' shipping trends. Salaries and wages also decreased as a result of lower performance-based and discretionary bonus compensation. These decreases were partially offset by the annual wage increase provided to our employees at the beginning of both September 2022 and 2023.

Current wording

Salaries, wages, and benefits increased $59.6 million, or 2.3%, in 2024 as compared to 2023, due to a $46.1 million increase in salaries and wages and a $13.5 million increase in employee benefit costs. The increase in salaries and wages was due primarily to the annual wage increase provided to our employees at the beginning of both September 2023 and 2024.

Previous wording

Our productive labor costs, which include wages for drivers, platform employees, and fleet technicians, increased as a percent of revenue to 23.6% in 2023 from to 22.9% in 2022. While our platform and P&D shipments per hour and P&D stops per hour improved during 2023 as compared to 2022, our linehaul laden load average declined due to the decreased operating density associated with the decrease in our LTL tons. Our other salaries and wages as a percent of revenue remained consistent between the comparable periods.

Current wording

Our productive labor costs, which include wages for drivers, platform employees, and fleet technicians, increased as a percent of revenue to 24.1% in 2024 from 23.6% in 2023. We continued to operate efficiently in 2024, despite the decrease in network density that generally results from the decline in volumes. Our P&D shipments and stops per hour both improved in 2024 as compared to 2023, which helped offset the reduction in our linehaul laden load factor. Our other salaries and wages as a percent of revenue also increased to 9.5% in 2024 as compared to 9.0% in 2023.

Previous wording

The cost attributable to employee benefits decreased $4.1 million, or 0.6%, in 2023 compared to 2022. Our employee benefit costs increased as a percent of salaries and wages to 37.5% in 2023 from 36.2% in 2022. The increase in employee benefit costs as a percent of salaries and wages was primarily due to an increase in our employee group health benefit costs that resulted from higher costs per claim. This increase in employee benefit costs as a percent of salaries and wages was partially offset by lower retirement benefit plan costs directly linked to our net income.

Current wording

The cost attributable to employee benefits increased $13.5 million, or 1.9%, in 2024 compared to 2023 due primarily to the annual wage increase as well as an increase in costs associated with our group health and dental plans. This increase in employee benefit costs was partially offset by lower retirement benefit plan costs directly linked to our net income. Our employee benefit costs as a percent of salaries and wages remained relatively consistent at 37.3% in 2024 compared to 37.5% in 2023.

Previous wording

Operating supplies and expenses decreased $134.6 million, or 15.8%, in 2023 as compared to 2022, due primarily to decreases in our costs for diesel fuel used in our vehicles. The cost of diesel fuel, excluding fuel taxes, represents the largest component of operating supplies and expenses, and can vary based on both the average price per gallon and consumption. Our average cost per gallon of diesel fuel decreased 19.8% in 2023 as compared to 2022. In addition, our gallons consumed decreased 8.5% in 2023 as compared to 2022 due to a decrease in our miles driven. We do not use diesel fuel hedging instruments; therefore, our costs are subject to market price fluctuations. Our other operating supplies and expenses as a percent of revenue were generally consistent in 2023 as compared to 2022.

Current wording

Operating supplies and expenses decreased $83.0 million, or 11.6%, in 2024 as compared to 2023, due primarily to decreases in our costs for diesel fuel used in our vehicles and lower maintenance and repair costs. The cost of diesel fuel, excluding fuel taxes, represents the largest component of operating supplies and expenses, and can vary based on both the average price per gallon and consumption. Our average cost per gallon of diesel fuel decreased 14.6% in 2024 as compared to 2023. We do not use diesel fuel hedging instruments; therefore, our costs are subject to market price fluctuations. Our gallons consumed also decreased 3.5% in 2024 as compared to 2023 due primarily to a decrease in our miles driven. Our other operating supplies and expenses as a percent of revenue decreased in 2024 as compared to 2023 due primarily to lower maintenance and repair costs, as we improved the average age of our fleet by consistently executing on our capital expenditure programs.

Previous wording

Depreciation and amortization increased $48.4 million, or 17.5%, in 2023 as compared to 2022. The increases in depreciation and amortization costs were due primarily to the assets acquired as part of our 2022 and 2023 capital expenditure programs. We believe depreciation costs will continue to increase in future periods based on our 2024 capital expenditure plan. While our investments in real estate, equipment, and technology can increase our short-term costs, we believe these investments are necessary to support our continued long-term growth and strategic initiatives.

Current wording

Depreciation and amortization increased $20.1 million, or 6.2%, in 2024 as compared to 2023. The increases in depreciation and amortization costs were due primarily to the assets acquired as part of our 2023 and 2024 capital expenditure programs. We believe depreciation costs will continue to increase in future periods based on our 2025 capital expenditure plan. While our investments in real estate, equipment, and technology can increase our short-term costs, we believe these investments are necessary to support our continued long-term growth and strategic initiatives.

Previous wording

Our effective tax rate in 2023 was 24.8% as compared to 25.2% in 2022. Our effective tax rate generally exceeds the federal statutory rate due to the impact of state taxes and, to a lesser extent, certain other non-deductible items.

Current wording

Our effective tax rate in 2024 was 23.9% as compared to 24.8% in 2023. Our effective tax rate generally exceeds the federal statutory rate due to the impact of state taxes and, to a lesser extent, certain other non-deductible items. In 2024, our effective tax rate was favorably impacted by the purchase of federal tax credits and other discrete tax adjustments.

Previous wording

The change in our cash flows provided by operating activities during 2023 as compared to 2022 was due to the $137.7 million decrease in net income as well as the $33.2 million decrease in certain other working capital accounts. These decreases were partially offset by a $48.4 million increase in depreciation and amortization expense.

Current wording

The change in our cash flows provided by operating activities during 2024 as compared to 2023 was due primarily to the $139.5 million increase in certain other working capital accounts partially offset by the $53.4 million decrease in net income.

Previous wording

The change in our cash flows used in investing activities during 2023 as compared to 2022 was primarily due to the timing of purchases and maturities of short-term investments, which was partially offset by a net reduction in capital expenditures. Changes in our capital expenditures are more fully described below in “Capital Expenditures.”

Current wording

The change in our cash flows used in investing activities during 2024 as compared to 2023 was primarily due to the timing of purchases and maturities of short-term investments and an increase in expenditures under our 2024 capital expenditure program. Additionally, we had lower proceeds from the sale of property and equipment in 2024 as compared to 2023. Changes in our capital expenditures are more fully described below in “Capital Expenditures.”

Previous wording

The change in our cash flows used in financing activities during 2023 as compared to 2022 was primarily due to the $823.6 million decrease in funds used for repurchases of our common stock. This decrease in cash was partially offset by higher dividend payments to our shareholders and a scheduled principal payment under our long-term debt agreement. Our return of capital to shareholders is more fully described below under “Stock Repurchase Program” and “Dividends to Shareholders.” Our long-term debt agreement is more fully described below under "Financing Arrangements."

Current wording

The change in our cash flows used in financing activities during 2024 as compared to 2023 was primarily due to higher repurchases of our common stock, as well as an increase in dividend payments to our shareholders during 2024.

Current wording

The table below sets forth our net capital expenditures for property and equipment for the years ended December 31, 2024 and 2023:

Previous wording

Our capital expenditures vary based upon the projected increase in the number and size of our service center facilities necessary to support our plan for long-term growth, our planned tractor and trailer replacement cycle, and forecasted tonnage and shipment growth. Expenditures for land and structures can be dependent upon the availability of land in the geographic areas where we are looking to expand. We historically spend 10% to 15% of our revenue on capital expenditures each year. We expect to continue to maintain a high level of capital expenditures in order to support our long-term plan for market share growth.

We historically spend 10% to 15% of our revenue on capital expenditures each year, and we generally expect to continue to maintain a level of capital expenditures in order to support our long-term plan for market share growth. There could be years, however, where our annual capital expenditures plan is above or below this range as we balance the size of our service center network and operating fleet with anticipated growth.

Previous wording

We currently estimate capital expenditures will be approximately $750 million for the year ending December 31, 2024. Approximately $350 million is allocated for the purchase of service center facilities, construction of new service center facilities or expansion of existing service center facilities, subject to the availability of suitable real estate and the timing of construction projects; approximately $325 million is allocated for the purchase of tractors and trailers; and approximately $75 million is allocated for investments in technology and other assets. We expect to fund these capital expenditures primarily through cash flows from operations, our existing cash and cash equivalents and, if needed, borrowings available under the Credit Agreement or Note Agreement. We believe our current sources of liquidity will be sufficient to satisfy our expected capital expenditures for the next twelve months and in the longer term.

Previous wording

Our revenue is generated from providing transportation and related services to customers in accordance with the bill of lading (“BOL”) contract, our general tariff provisions and contractual agreements. Generally, our performance obligations begin when we receive a BOL from a customer and are satisfied when we complete the delivery of a shipment and related services. We recognize revenue for our performance obligations under our customer contracts over time, as our customers receive the benefits of our services in accordance with Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers ("ASC Topic 606"). With respect to services not completed at the end of a reporting period, we use a percentage of completion method to allocate the appropriate revenue to each separate reporting period. Under this method, we develop a factor for each uncompleted shipment by dividing the actual number of days in transit at the end of a reporting period by that shipment’s standard delivery time schedule. This factor is applied to the total revenue for that shipment and revenue is allocated between reporting periods accordingly. A hypothetical change of 10% in our percentage of completion estimate would not have a material effect on our recorded revenue.

Previous wording

In establishing accruals for claims and expenses, we evaluate and monitor each claim individually, and we use factors such as historical claims development experience, known trends and third-party actuarial estimates to determine the appropriate reserves for potential liabilities. We believe the assumptions and methods used to estimate these liabilities are reasonable; however, any changes in the severity or number of reported claims, significant changes in medical costs and regulatory changes affecting the administration of our plans could significantly impact the determination of appropriate reserves in future periods. Our accrued liability for insurance, BIPD claims, and workers’ compensation claims totaled $127.0 million and $129.6 million at December 31, 2023 and 2022, respectively. Claims and insurance accruals are discussed further in Note 1 of the Notes to the Financial Statements included in Item 8 of this report.

In establishing accruals for claims and expenses, we evaluate and monitor each claim individually, and we use factors such as historical claims development experience, known trends and third-party actuarial estimates to determine the appropriate reserves for potential liabilities. We believe the assumptions and methods used to estimate these liabilities are reasonable; however, any changes in the severity or number of reported claims, significant changes in medical costs and regulatory changes affecting the administration of our plans could significantly impact the determination of appropriate reserves in future periods. Our accrued liability for BIPD and workers’ compensation claims totaled $137.3 million and $127.0 million at December 31, 2024 and 2023, respectively. Claims and insurance accruals are discussed further in Note 1 of the Notes to the Financial Statements included in Item 8 of this report.
