Business

The Company provides national less-than-truckload (LTL) services through a single integrated organization. While approximately 97 percent of its revenue has been derived from transporting LTL shipments across the contiguous United States, the Company also offers customers a wide range of other value-added services, including non-asset truckload, expedited transportation and logistics services across North America. The Company’s customer base is diversified across numerous industries.

Revenue Recognition

The Company’s revenues are derived primarily from the transportation of freight as it satisfies performance obligations that arise from contracts with its customers. The Company’s performance obligations arise when it receives a bill of lading (BOL) to transport a customer's commodities at negotiated prices contained in either a transportation services agreement or a publicly disclosed tariff rate. Once a BOL is received and accepted, a legally-enforceable contract is formed whereby the parties are committed to perform and the rights of the parties, shipping terms and conditions, and payment terms have been identified. Each shipment represents a distinct service that is a separately identified performance obligation.

The typical transit time to complete a shipment is fromone tofive days. Billing for transportation services normally occurs after completion of the service and payment is generally due within 30 days after the invoice date. The Company recognizes revenue related to the Company’s LTL, non-asset truckload and expedited transportation services over the transit time of the shipment as it moves from origin to destination based on the transit status at the end of each reporting period.

Key estimates included in the recognition and measurement of revenue and related accounts receivable are as follows:

•

Revenue associated with shipments in transit is recognized ratably over the transit time; and

•

Adjustments to revenue for billing adjustments and collectability.

The portion of the gross invoice related to interline transportation services that involve the services of another party, such as another LTL service provider, is not recorded in the Company’s revenues. Revenue from logistics services is recognized as the services are provided.

Claims and Insurance Accruals

The Company maintains insurance coverage with third-party insurance carriers that provides various levels of protection for covered risk exposure, including in the areas of workers’ compensation, bodily injury and property damage, casualty, cargo loss and damage and group health, with coverage limits and retention and deductible amounts that vary based on policy periods and claim type. Claims and insurance accruals related to workers’ compensation, bodily injury and property damage, casualty, cargo loss and damage and group health are established by management based on estimates of losses that the Company will ultimately incur on reported claims and on claims that have been incurred but not yet reported. Accruals are calculated on reported claims based on an evaluation of the nature and severity of the claim, historical loss experience and on legal, economic and other factors. Actuarial analysis is also used in calculating the accruals for workers’ compensation and bodily injury and property damage claims.

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation. The Company periodically evaluates estimated useful lives of property and equipment considering its planned and actual usage, planned and actual maintenance and replacement, and other relevant physical and economic factors that may affect our use of the assets. During the second quarter of 2024, the Company determined that the estimated useful lives of certain of its trailers and dollies should be extended from 14 years to 20 years. This change is recognized prospectively. The changes in estimates resulted in an increase in income from continuing operations of approximately $2.9 million (a $2.2 million increase in net income) for the nine months ended September 30, 2025.

Segment Reporting

Saia is comprised of a single reportable segment organized around its transportation services. The measure of segment assets is reported on the balance sheet as total consolidated assets.

The following table presents selected financial information with respect to the Company’s single reportable segment (in thousands):

(a)Wages includes payroll costs for non-management employees generally paid on an hourly or per-mile basis. Salaries includes payroll costs for exempt employees.

(b)Other segment items include employees' benefits, fuel, operating expenses and supplies, operating taxes and licenses and claims and insurance.

(2) Computation of Earnings Per Share

For the quarter and nine months ended September 30, 2025, there were 11,834 anti-dilutive share-based awards. For the quarter and nine months ended September 30, 2024, there wereno anti-dilutive share-based awards.

(3) Commitments and Contingencies

The Company is subject to legal proceedings that arise in the ordinary course of its business. Management believes that adequate provisions for the resolution of all contingencies, claims and pending litigation have been made for probable and estimable losses and that the ultimate outcome of these actions will not have a material adverse effect on its financial condition but could have a material adverse effect on the results of operations in a given quarter or annual period.

(4) Fair Value of Financial Instruments

The carrying amounts of financial instruments including cash and cash equivalents, accounts receivable, accounts payable and short-term debt approximated fair value as of September 30, 2025 and December 31, 2024, because of the relatively short maturity of these instruments. Based on the borrowing rates currently available to the Company for debt with similar terms and remaining maturities, the estimated fair value of total debt at September 30, 2025 and December 31, 2024 was $220.0 million and $200.5 million, respectively. The fair value of fixed rate debt is based on current market interest rates for similar types of financial instruments, reflective of level two inputs. The carrying amount of the Company’s variable rate debt approximates fair value as interest rates approximate the current rates available to the Company. The carrying value of the debt was $219.2 million and $200.3 million at September 30, 2025 and December 31, 2024, respectively.

(5) Debt and Financing Arrangements

Credit Arrangements

Revolving Credit Facility

The Company is a party to an unsecured credit agreement with its banking group (the Revolving Credit Facility). On December 9, 2024, the Company entered into an amendment to the Revolving Credit Facility. The amendment increased commitments under the Revolving Credit Facility by $300 million to an aggregate commitment of $600 million and expanded the accordion feature, subject to certain conditions and availability of lender commitments, from $150 million to $300 million. This amendment also extended the maturity date of the Revolving Credit Facility from February 3, 2028, to December 9, 2029. Borrowings under the Revolving Credit Facility bear interest at the Company’s election at a variable rate equal to (a) one, three or six month term SOFR (the forward-looking secured overnight financing rate) plus 0.10%, or (b) an alternate base rate, in each case plus an applicable margin. Additionally, the amendment adjusted the applicable margin such that the applicable margin is now between 1.25% and 2.00% per annum for term SOFR loans and between 0.25% and 1.00% per annum for alternate base rate loans, in each case based on the Company’s consolidated net lease adjusted leverage ratio. The amendment also modified the fees that the Company accrues based on the daily unused portion of the credit facility, which will now range between 0.175% and 0.30% based on the Company’s consolidated net lease adjusted leverage ratio. The Revolving Credit Facility contains certain customary representations and warranties, affirmative and negative covenants and provisions relating to events of default. Under the Revolving Credit Facility, if an event of default occurs, the banks will be entitled to take various actions, including the acceleration of amounts due. Under the Revolving Credit Facility, the Company is subject to a maximum consolidated net lease adjusted leverage ratio of less than 3.50 to 1.00 with the potential to be temporarily increased in the event the Company makes an acquisition that meets certain criteria. The Company was in compliance with its debt covenants under the Revolving Credit Facility at September 30, 2025.

At September 30, 2025, the Company had outstanding borrowings of$118.0 million and outstanding letters of credit of $36.4 million under the Revolving Credit Facility. At December 31, 2024, the Company had outstanding borrowings of$94.0 million and outstanding letters of credit of $32.2 million under the Revolving Credit Facility. At September 30, 2025, the Company had $445.6 million in availability under the Revolving Credit Facility.

Private Shelf Agreement

On November 9, 2023, the Company entered into a $350 million uncommitted Private Shelf Agreement (the Shelf Agreement) with PGIM, Inc. (Prudential) and certain affiliates and managed accounts of Prudential (the Note Purchasers), which allows the Company, from time to time, to offer for sale to Prudential and its affiliates, in one or a series of transactions, senior notes of the Company, through November 9, 2026.

Pursuant to the Shelf Agreement, on May 1, 2024, the Company issued senior promissory notes (the Initial Notes) in an aggregate principal amount of $100 million to the Note Purchasers. The Initial Notes bear interest at 6.09% per annum and mature on May 1, 2029, unless repaid earlier by the Company. The Initial Notes are senior unsecured obligations and rank pari passu with borrowings under the Revolving Credit Facility or other senior promissory notes issued pursuant to the Shelf Agreement.

Additional notes issued under the Shelf Agreement, if any, would bear interest at a rate per annum, and would have such other terms, as would be set forth in a confirmation of acceptance executed by the parties prior to the closing of the applicable sale transaction.

The Shelf Agreement requires that the Company maintain a consolidated net lease adjusted leverage ratio of less than 3.50 to 1.00, with limited exceptions. The Shelf Agreement also contains certain customary representations and warranties, affirmative and negative covenants and provisions related to events of default. Upon the occurrence and continuance of an event of default, the holders of notes issued under the Shelf Agreement may require immediate payment of all amounts owing under such notes. The Company was in compliance with its debt covenants under the Shelf Agreement at September 30, 2025.

At September 30, 2025 and December 31, 2024, the Company had outstanding notes under the Shelf Agreement of$100.0 million.
