Saia (SAIA) posts 2025 flat $3.2B sales but lower operating profit

Q: How did Saia, Inc. (SAIA) perform financially in 2025?

Saia generated 2025 revenue of $3.2 billion , unchanged from 2024, but operating income declined to $352.2 million from $482.2 million . This indicates margin pressure and higher costs despite stable top-line performance across its nationwide less-than-truckload network.

Q: What is Saia, Inc.’s core business and operating footprint?

Saia operates a national less-than-truckload (LTL) network, providing freight services across the 48 contiguous states with partners into Canada and Mexico. As of December 31, 2025, it ran 213 terminals, around 7,700 tractors and 26,500 trailers, plus additional offices and a warehouse.

Q: How large is Saia’s workforce and what is its labor model?

Saia reports nearly 14,500 union-free employees, with about 51% commercial drivers and 24% dock workers. It focuses on direct employee relationships, competitive pay, health and wellness benefits, training, safety programs and a dock-to-driver pathway to support retention and operational flexibility without collective bargaining agreements.

Q: What capital spending does Saia plan for 2026?

Saia anticipates net capital expenditures of about $350 million to $400 million in 2026. Planned investments target new and existing terminals, additional tractors and trailers, and advanced technologies to support network growth, operational efficiency, safety and the company’s long-term less-than-truckload expansion strategy.

Rhea-AI Filing Summary

Saia, Inc. reports 2025 results showing flat revenue but lower profitability. The company generated $3.2 billion in revenue in both 2025 and 2024, while operating income declined to $352.2 million from $482.2 million, reflecting margin pressure despite stable top-line performance.

Saia operates a national less‑than‑truckload network with 213 terminals, about 7,700 tractors and 26,500 trailers, and has invested over $2.5 billion in capital expenditures over the past five years to expand its footprint and modernize its fleet and technology. The business is exposed to driver shortages, regulatory changes, environmental rules, cybersecurity risk, and significant ongoing capital needs, but emphasizes safety, service quality, and human-capital investments across a nearly 14,500‑employee, union‑free workforce.

Positive

None.

Negative

Profitability deterioration despite flat revenue: 2025 operating income declined to $352.2 million from $482.2 million in 2024 on unchanged $3.2 billion revenue, indicating materially weaker margins.

Insights

Flat revenue with a sharp profit drop and heavy capex reshape Saia’s risk-reward.

Saia held 2025 revenue at $3.2 billion, matching 2024, but operating income fell to $352.2 million from $482.2 million. That points to higher costs or mix headwinds compressing margins even as volumes and pricing supported the top line.

Management highlights more than $2.5 billion in five‑year capital spending on terminals, tractors, trailers and technology, plus an expanded network of 213 terminals and a 7,700‑tractor, 26,500‑trailer fleet. These investments aim to support growth, service quality and sustainability but raise ongoing cash needs.

Risk disclosures stress driver and labor shortages, inflation, regulatory and environmental mandates, cyber threats, and unionization risk across a nearly 14,500‑employee, union‑free workforce. With 2026 capex guided to $350–$400 million, future filings will clarify whether margin pressure eases as new capacity and efficiency initiatives mature.

Item 1. Business

Overview

Saia, Inc., through its wholly-owned subsidiaries, is a transportation company headquartered in Johns Creek, Georgia (Saia, Inc. together with its subsidiaries, the Company or Saia). We provide national less-than-truckload (LTL) services through a single integrated organization. While approximately 97% of our revenue is derived from transporting LTL shipments, we also offer customers a wide range of other value-added services, including brokered truckload and expedited transportation and other logistics services across North America.

Founded in 1924, Saia Motor Freight Line, LLC (Saia LTL Freight), a wholly-owned subsidiary of Saia, Inc., is a leading LTL carrier that provides direct service to the 48 contiguous states and provides LTL services to Canada and Mexico through relationships with third-party interline carriers. Saia LTL Freight specializes in offering its customers a range of LTL services including time-definite and expedited options. Saia LTL Freight primarily provides its customers with solutions for shipments between 100 and 10,000 pounds.

As of December 31, 2025, Saia operated a network comprised of 213 owned and leased terminals, plus three general offices and one warehouse. At December 31, 2025, Saia LTL Freight owned approximately 7,700 tractors and 26,500 trailers, including equipment acquired with finance leases.

Over the past five years, Saia has invested in excess of $2.5 billion in capital expenditures, primarily for real estate, revenue equipment and technology. These real estate investments have been made to support Saia’s long-term strategy of expanding our footprint in both new and existing markets in order to be closer to our customers and position us to gain market share. Investments in equipment and technology have supported this growth while maintaining and modernizing our fleet, resulting in improved fuel efficiency, enhanced safety features and reduced carbon emissions. In addition, we have invested in technology to strengthen our network and operations, including network optimization, advanced data analytics for operational and profitability insights, customer service enhancements, training and streamlined business processes.

In 2025, Saia generated revenue of $3.2 billion and operating income of $352.2 million compared to revenue of $3.2 billion and operating income of $482.2 million in 2024. In 2025, the average Saia LTL Freight shipment weighed approximately 1,380 pounds and traveled an average distance of approximately 897 miles. In 2024, the average Saia LTL Freight shipment weighed approximately 1,343 pounds and traveled an average distance of approximately 891 miles.

Industry

The trucking industry consists of three categories: private fleets and two categories of “for-hire” carriers. The private fleets are owned and operated by shippers that use their own equipment to transport their products. The two “for-hire” carrier categories - truckload and LTL - are generally distinguished by shipment sizes handled by the transportation service companies. Truckload carriers typically handle shipments greater than 10,000 pounds, while LTL carriers generally transport shipments under that threshold. Saia operates primarily as an LTL carrier. In addition to the three main trucking categories, Saia also competes with small package carriers, final mile delivery services, railroads, air freight carriers, third party logistics providers and other emerging digital competitors.

LTL carriers typically pick up numerous shipments, generally ranging from 100 to 10,000 pounds, consolidate them at local carrier-operated freight terminals and then transport the shipments from the terminal to the carrier-operated destination terminal for delivery to the ultimate destination. As a result, LTL carriers require expansive networks of pick-up and delivery operations around local freight terminals and linehaul operations to transport freight between the local terminals.

The truckload category is the largest portion of the “for-hire” carrier market. Truckload carriers primarily transport large shipments from origin to destination with no intermediate handling.

Because truckload carriers do not require an expansive network to provide point-to-point service, the overall cost structure of truckload carriers is typically lower and more variable relative to LTL carriers. However, the lack of a network can subject their drivers to extended periods away from home, often resulting in higher driver turnover and periodic driver shortages. The truckload category is comprised of several major carriers and numerous small entrepreneurial players. At the most basic level, a truckload carrier can be started with capital for rolling stock (a tractor and a trailer), insurance, a driver and little else. As truckload carriers become larger in scale, capital is needed for technology, infrastructure and some limited facilities. Saia may participate in the truckload market as a means to fill empty miles in lanes that are not at capacity. Saia also offers its customers the truckload and expedited offerings of its logistics operations.

Capital requirements are significantly higher in the traditional LTL category versus the truckload category. In the LTL sector, substantial amounts of capital are required for a network of freight terminals, shipment handling equipment and revenue equipment (both for city pick-up, delivery and linehaul). In addition, investment in technology has become increasingly important in the LTL category largely due to the number of transactions and number of customers served on a daily basis. Saia LTL Freight picks up approximately 35,000 shipments per day, each of which has a shipper, a consignee and sometimes a third-party payor, all of whom need access to information in a timely manner. In addition to customer service, technology plays a key role in improving operational efficiency and compliance, as well as safety and revenue management. As a result of the significant infrastructure required to operate an LTL carrier, the LTL category is more concentrated than the truckload category with the largest LTL players operating nationally or in regional markets. Driver turnover in the LTL sector is significantly lower relative to the truckload sector, although LTL carriers also face periodic driver shortages.

Business Strategy

Saia has grown historically through a combination of organic growth and geographic integration or “tuck-in” acquisitions of smaller trucking and logistics companies. In recent years, Saia has largely grown through organic growth, which it intends to continue going forward.

Key elements of our business strategy include:

Operate safely.

Our most valuable resource is our employees. It is a corporate priority to continuously emphasize the importance of safe operations to reduce both the frequency and severity of injuries and accidents. As part of our ongoing replacement and expansion of our tractor fleet, we have incorporated accident avoidance technologies in our new over-the-road tractors. These features include active braking assistance, adaptive cruise control, lane departure warning systems and roll stability control. This emphasis on safe operations is important to protecting our employees and the communities in which we operate. A safety first focus has the added benefit of helping to control inflationary insurance costs.

Employee engagement.

We are focused on maintaining strong relationships with our employees. We invest in our employees through training and professional development programs, safety training, wellness programs, internal employee communications and employee recognition programs, along with providing competitive wages and employee benefit programs. For further information on employee engagement efforts, see Human Capital Management section below.

Manage pricing and business mix.

This element of our business strategy focuses on optimizing both the pricing of our services and the mix of freight we handle to enhance the overall profitability of our network. In recent years, our expanded geographic footprint and strengthened service offerings have enabled us to deliver differentiated solutions to customers, contributing to increases in revenue per shipment, excluding fuel surcharges.

Increase density in existing geographies.

We gain operating leverage by growing volume and density within our existing geography. Depending on general economic conditions, pricing and the specific geography, we estimate that the potential incremental profitability on growth in current markets can be significant. We continuously evaluate opportunities to expand our terminal network in new and existing markets that demonstrate sufficient long-term demand. Future volume growth at Saia may result from improvements in broader economic conditions, industry consolidation, continued geographic expansion, strategic acquisitions, and targeted sales and marketing initiatives designed to enhance customer engagement and support sustained growth.

Deliver best-in-class service.

The foundation of our growth strategy is the consistent delivery of high quality service, demonstrated through reliable on-time delivery and reduced claims for lost or damaged freight. Our customers place significant value on service quality, which supports our ability to obtain appropriate compensation for the services we provide and enhances our positioning to capture additional market share.

Improve operating efficiencies.

We have operating initiatives focused on continuing to improve efficiency, including optimizing our linehaul and pick-up and delivery operations. These initiatives help offset a variety of structural cost increases like wages, healthcare benefits, casualty claims and related insurance, workers’ compensation claims and parts and maintenance expense. Enhancing the efficiency of our linehaul and pick‑up and delivery operations supports more effective utilization of our employees, equipment and resources. These efforts also contribute to reductions in fuel consumption and associated carbon emissions, consistent with our broader sustainability objectives and our commitment to minimizing the environmental impact of our operations. We believe we remain well positioned to manage costs effectively, optimize asset utilization and explore additional opportunities for incremental cost savings.

Grow geographic terminal footprint.

We intend to continue pursuing geographic expansion and build additional density in key markets to support profitable growth and strengthen our customer value proposition. Accordingly, we plan to continue investing in new terminals, in our tractor and trailer fleet and in advanced technologies to enable us to efficiently handle the increased volume we anticipate across both new and existing markets. In addition to organic expansion through new terminal openings, we may evaluate strategic acquisition opportunities from time to time to further extend our geographic reach, increase network density and acquire complementary customer bases.

Address environmental impact of our operations.

We are dedicated to building on our strong, positive culture by being a leading corporate citizen for the benefit of our customers, employees, communities and stockholders. In recent years, we have made significant investments in our tractor and trailer fleet to improve fuel efficiency, reduce emissions, and enhance safety, reliability and maintenance performance. We are also working to optimize our linehaul scheduling and pick-up and delivery operations to improve asset utilization as well as further reduce fuel consumption and related emissions. Since the formalization of our sustainability program in 2022, we have scaled the use of alternative fuels utilizing renewable diesel, compressed natural gas (CNG) vehicles running renewable natural gas (RNG) and battery electric vehicles. We operate a fleet of over 55 CNG vehicles and continue to evaluate the expanded use of alternative and renewable fuels to power our fleet. We have procedures that are designed to reduce the risk of spills of hazardous materials that we transport and to quickly and efficiently react to any environmental incidents. At our terminals, we have

implemented energy-saving procedures, and maintain programs to recycle used oil, scrap metal, paper, tires and batteries. We also incorporate sustainability-focused practices and design elements into newly constructed facilities where practicable.

Based on the most recently available rankings, for 2024, Saia continued to maintain high marks in the EPA’s SmartWay Carrier Performance Rankings for LTL carriers for nitrogen oxide and particulate matter emissions per ton-mile. We have also participated in the EPA’s SmartWay Program since 2006, which assists companies with advancing supply chain sustainability by measuring, benchmarking and improving freight transportation efficiency.

Seasonality

Our business is subject to seasonal variations. Customers tend to reduce shipments after the winter holiday season, and our operating expenses tend to be higher as a percent of revenue in the winter months primarily due to lower capacity utilization and weather effects. Generally, the first quarter is the weakest quarter while the second and third quarters are the strongest quarters in terms of revenue and profit. Quarterly profitability is also impacted by the timing of salary and wage increases and general rate increases, which have varied over the years.

Human Capital

We believe our success depends on the strength of our workforce. Our Executive Vice President and Chief Human Resources Officer, reporting to our President and Chief Executive Officer, is responsible for developing and executing our human capital strategy. These responsibilities include recruiting, hiring, training and retention, as well as the development of our compensation and benefits programs.

Our nearly 14,500 union-free employees are comprised of about 51% licensed commercial drivers, about 24% dock workers (approximately 22% of whom are part-time) and the remaining 25% work in sales, technology and administration to support our business. Approximately 89% of our workforce is male. Approximately 49% of our employees have self-identified as Hispanic or Latino, Native American, Pacific Islander, Asian, Black or African American, or of two or more races. Additionally, approximately 74% of our workforce is under the age of 55.

As the success of our business is fundamentally connected to the well-being of our people, we offer benefits that support their physical, financial and emotional well-being. We provide our employees and their families with access to affordable and convenient medical, dental and vision programs. To foster retention, employees with ten or more years of service do not pay premiums for participation in the medical program. Additionally, we strive to help employees lead healthier lives through a voluntary wellness program aimed at engaging employees to promote proactive evaluation, tracking and management of major health and wellness indicators. To support employee participation in our benefit programs, we have continued to absorb market-driven cost increases in coverage for group health insurance. As a result, employees have experienced only minimal premium increases for these programs over the past several years.

As an added benefit for employees, we offer a 401(k) savings plan with a Company match as well as paid vacation and personal days. These benefits are in addition to the Company’s market-based compensation program designed to maintain competitive compensation packages for all employees. We assess the competitiveness of our compensation by principal job classifications in markets across the country through periodic compensation surveys. Company-wide wage increases are also implemented from time-to-time, including an approximate 3.0% wage increase in October 2025, excluding executives.

In recent years, competition for qualified employees has narrowed the historical compensation gap between union and non-union carriers. We believe that maintaining a direct relationship with our employees provides for better communications and employee relations, which enhances operational flexibility and contributes to lower overall costs. In addition, non-union carriers have more flexibility with respect to work schedules, routes and other similar items. This flexibility is a major consideration in meeting the service levels required by customers. We believe this differentiation provides stronger future growth prospects, improved operating efficiencies and enhanced customer service capabilities.

Recruiting, Hiring, Training and Professional Development.

We seek to hire employees with the desire that they spend their career with us to retirement. With that in mind, identifying qualified candidates and attracting them with competitive compensation and benefits is key to our success. We have regional recruiting managers across the Company to help meet our hiring needs. If necessary, and to attract the most qualified candidates, we offer periodic signing bonuses to new hires.

More than 300 of our drivers also serve as driver trainers to assist in providing all new drivers with over 80 hours of training. We annually train drivers in defensive driving processes with emphasis on special operations in addition to weekly safety training through various mediums, including videos and group and individual presentations on diverse safety topics. Our tractor fleet is equipped with extensive safety technology, including video recording systems which enable managers to provide coaching and feedback to drivers throughout the year. Our dock employees also receive onboarding instruction which is supplemented with on-going safety and job training. Employees who express an interest in a long-term driving career can enroll in a Company-sponsored dock-to-driver program to obtain the necessary commercial driver certifications. Annual safety awards and recognition are given to drivers, mechanics and dock employees who qualify.

Employee Engagement.

We focus on driving employee engagement throughout our organization. We believe it is important to our success as an organization for our employees to understand how their work contributes to our overall performance. We communicate with our workforce through a variety of channels and encourage open and direct communication. Our communication starts with an employee’s manager and is supplemented by a variety of means, including regular industry updates, an internally distributed magazine, reports on quarterly performance directly from the CEO and executive team and annual employee engagement surveys.

We are committed to fostering a work environment that values collaboration, fairness, and employee growth. We pride ourselves on the equitable treatment of our employees and aim to achieve high levels of employee satisfaction and productivity. We use periodic engagement and compensation surveys to evaluate our efforts in meeting employee needs and driving organizational success.

We seek to create a culture that encourages authenticity and values unique perspectives. By fostering an environment that highlights shared experiences and celebrates individual contributions, we empower our employees to achieve excellence.

Saia’s commitment to fostering a culture of engagement, innovation and collaboration is exemplified by our emphasis on retention, leadership development and opportunities for employee growth. This approach ensures alignment with our core values of safety and taking care of each other.

Our workforce engagement efforts reflect a cross-functional perspective on fostering collaboration and fairness, as we strive to promote a workplace where all employees feel valued for their contributions. Through ongoing evaluation of processes and programs, we focus on attracting, developing and retaining top talent.

Competition

Although industry capacity has tightened somewhat and consolidation has occurred among certain carriers, shippers continue to have a broad range of transportation options. We believe that service quality, pricing, geographic coverage, breadth of service offerings, responsiveness and operational flexibility remain the primary factors that differentiate competitors within our industry.

Saia provides LTL services in a highly competitive environment against a wide range of transportation service providers. These competitors include a small number of large, national transportation service providers in the long haul and two-day LTL markets and a larger number of shorter-haul or regional transportation companies in the two-day and overnight LTL markets. The larger the service area, the greater the barriers to entry into the LTL trucking category due to the need for additional equipment and freight terminals associated with this coverage. The level of technology investment required and density needed to provide adequate labor and asset utilization make larger-scale entry into the LTL market difficult. Saia also competes against several modes of transportation, including truckload

and private fleets, small package carriers, final mile delivery services, railroads, air freight carriers, third party logistics providers and other emerging digital competitors.

Regulation

The trucking industry is subject to regulation by many federal, state and local government agencies in the U.S., and these authorities have broad powers over matters ranging from the authority to engage in motor carrier operations, motor carrier registration, driver hours of service, safety and fitness of transportation equipment and drivers, port security, insurance requirements, employment practices, taxation, data privacy and security, certain mergers and acquisitions, financial reporting, fuel efficiency and emissions standards and the transportation and handling of hazardous materials. Regulatory requirements, and changes in regulatory requirements or guidance, may adversely affect our business or the economics of the industry by requiring changes in operating practices that could influence the demand for and increase the costs of providing transportation services.

Key areas of regulatory activity include:

Department of Transportation.

Motor carrier and freight brokerage operations are subject to safety, insurance and bonding requirements prescribed by the U.S. Department of Transportation (DOT) and various state agencies. We are also subject to a variety of vehicle registration and licensing requirements in certain states and local jurisdictions where we operate. Matters such as weight and equipment dimensions are also subject to U.S. federal and state regulation.

Within the DOT, the Federal Motor Carrier Safety Administration (FMCSA) has issued rules, including hours of service regulations that limit the maximum number of hours a driver may be on duty between mandatory off-duty hours and require driver rest breaks. The rules provide that a truck driver may work no more than a maximum of 60 hours within seven consecutive days and 70 hours within eight consecutive days. FMCSA rules further impose a maximum work period of 14 hours (no more than 11 hours of which may be driving time) after first coming on-duty following 10 consecutive hours of off-duty time. Drivers are also required to take a 30-minute break prior to driving beyond 8 hours.

The FMCSA’s Compliance Safety Accountability Program (CSA) is an enforcement and compliance model that assesses a motor carrier’s on-road performance and investigation results for a 24-month period using roadside stops and inspections, resulting in safety and performance ratings in the following categories: unsafe driving; hours-of-service compliance; driver fitness; controlled substances/alcohol; vehicle maintenance; hazardous material compliance; and crash indicators. The evaluations are used to rank carriers and individual drivers and to select carriers for audit and other interventions or enforcement action.

The FMCSA maintains the Commercial Driver’s License Drug and Alcohol Clearinghouse (DAC), which is a database that discloses drug and alcohol violations of commercial motor vehicle drivers. The DAC requires us to check for current and prospective employees’ drug and alcohol violations and annually query for violations of each driver we employ. Drivers with a prohibited status in the DAC will have their state issued commercial driver licenses downgraded and will be unable to continue driving with such until they complete the return-to-duty process. All states are required to check the clearinghouse for any prohibitions before issuing, renewing, transferring or upgrading any commercial driver licenses.

Pursuant to an executive order in April 2025, the FMCSA updated its “out-of-service” criteria strengthening the enforcement of English language proficiency requirements for commercial drivers. Pursuant to the updated criteria, law enforcement must forbid a driver from operating a commercial vehicle if the driver fails a two-part interview and road sign test. In September 2025, the DOT and the FMCSA issued a temporary regulation strengthening the requirements for obtaining and renewing non-domiciled commercial driver licenses (CDLs). The regulation, which is pending judicial review, also directs state licensing agencies to revoke unlawfully issued non-domiciled CDLs. In February 2026, DOT and the FMCSA issued a final rule substantively reaffirming the September 2025 temporary regulation. The final rule requires states to issue non‑domiciled CDLs only to applicants with certain visa status

supported by proper passport and immigration documentation, and to verify before issuing a license each applicant’s lawful status through the national Systematic Alien Verification for Entitlements system.

Department of Homeland Security.

Federal, state and municipal authorities have implemented anti-terrorism measures, including checkpoints and travel restrictions on large trucks. The Transportation Security Administration (TSA) and Customs and Border Protection (CBP) continue to focus on trailer security, driver identification, security clearance and border-crossing procedures. In addition, we must comply with U.S. Citizenship and Immigration Services regulations regarding the eligibility of our employees to work in the U.S. These and other safety and security measures, such as rules for transportation of hazardous materials and cargo-security regulations, could increase the cost of operations, reduce the number of qualified drivers and disrupt or impede the timing of our deliveries to customers.

Environmental Regulations.

Our operations are subject to federal, state, local, and foreign regulations with regard to air and water quality and other environmental matters. Regulation in this area continues to evolve with changes in the enforcement of existing regulations, as well as the enactment and enforcement of new regulations that may require us or our customers to modify, supplement or replace equipment or facilities or to change or discontinue present methods of operation. Specifically, the U.S. Environmental Protection Agency (EPA) has issued regulations reducing the sulfur content of diesel fuel and reducing engine emissions.

Our operations are subject to environmental laws and regulations dealing with the handling of hazardous materials, underground fuel storage tanks and discharge and retention of storm water. We operate in industrial areas where truck terminals and other industrial activities are located and where groundwater or other forms of environmental contamination may have occurred. Under existing law, we could be held responsible for costs related to environmental contamination at or emanating from our current and past facilities and at third party waste disposal sites. Our operations involve the risks of fuel spillage or seepage, environmental damage and hazardous waste disposal and costs associated with the leakage or discharge of hazardous materials we transport for our customers, among others. Violations of applicable environmental laws or regulations or spills or other accidents involving hazardous substances may subject us to cleanup costs, liabilities not covered by insurance, substantial fines or penalties and to civil and criminal liability, any of which could adversely affect our financial condition, results of operations, liquidity and cash flows.

Clean Trucks Plan.

In 2021, the EPA announced its “Clean Trucks Plan” (CTP), which aimed to develop new rules over a three-year timeframe to reduce greenhouse gas emissions and other air pollutants from heavy-duty trucks while accelerating the transition to lower‑emission and zero‑emission technologies. In 2022, the EPA finalized the first phase of the CTP, also known as the Heavy-Duty NOx rule, by adopting a final rule setting more stringent nitrogen oxides emission standards for new heavy-duty vehicles and engines starting in model year 2027. In 2024, the EPA approved a new rule as Phase 3 under the CTP regarding greenhouse gas standards for the manufacture, sale, or importation of heavy-duty trucks that aims to reduce greenhouse gas emissions by up to 60% by 2032 for some vehicle classes. The standards apply to heavy-duty vehicles manufactured starting in model year 2028 through model year 2032 and revise certain greenhouse standards for model year 2027 that were established under the prior rulemaking. In March 2025, the EPA reopened and reconsidered key regulations related to the CTP, including the Phase 3 greenhouse gas standards, the Heavy‑Duty NOx rule, and the light‑ and medium‑duty vehicle emissions standards, framing them as overly costly and burdensome. In July 2025, the administration proposed eliminating all existing federal greenhouse gas standards for light-, medium-, and heavy‑duty vehicles dating back to 2010. Concurrently, the EPA announced a broader reevaluation of the CTP, citing industry concerns regarding infrastructure readiness, vehicle costs, operational feasibility, and supply‑chain impacts.

California Air Resources Board (CARB).

Several states have enacted legislation relating to engine emissions, trailer regulations, fuel economy, and/or fuel formulation, such as regulations issued by CARB. CARB regulations apply to both in-state California carriers and carriers outside of California who own or dispatch equipment in the state. In 2021, CARB adopted more stringent standards to reduce nitrogen oxide emissions by heavy-duty engines. CARB has also adopted regulations to accelerate large-scale transition in California to zero-emission medium and heavy-duty trucks, including trucks of a type used in our operations in California.

In 2023, California enacted two climate disclosure laws – SB 253 and SB 261. Senate Bill 253 will require companies with revenues greater than $1 billion doing business in California to comprehensively report their Scope 1, 2, and 3 emissions and to obtain a third-party audit. Despite delays in promulgating rules, SB 253 is anticipated to be implemented in 2026. Senate Bill 261 requires U.S. businesses with over $500 million in revenue operating in California to disclose climate-related financial risks and mitigation plans biannually. In November 2025, the United States Court of Appeals for the Ninth Circuit granted an injunction pausing implementation of Senate Bill 261.

Advanced Clean Trucks.

CARB’s Advanced Clean Trucks (ACT) regulation requires truck manufacturers to sell zero-emission trucks as an increasing percentage of their annual California sales. By 2035, zero-emission truck/chassis sales must account for 40% of truck tractor sales in the state. Numerous other states have adopted or are in the process of adopting regulations similar to the ACT regulation. In June 2025, the current administration overturned several EPA waivers granted to California including the waiver for the ACT regulation. Litigation regarding the administration’s actions is ongoing.

Advanced Clean Fleets.

In 2023, CARB adopted the Advanced Clean Fleets (ACF) regulation mandating that operators of 50 or more trucks must operate fleets comprised of an increasing percentage of zero-emission vehicles. The regulation includes a phase-in period from 2027 to 2045, depending on the class of vehicle. In January 2025, CARB withdrew its request to the EPA for a waiver that would have allowed it to adopt and enforce the ACF standards. In October 2025, in response to lawsuits brought by a coalition of states and trucking industry groups, CARB agreed to repeal portions of the ACF regulation, including the high-priority fleet and drayage fleet provisions. As a part of the settlement, CARB also agreed not to enforce the ACF regulation’s 2036 mandate requiring 100% zero-emission sales of new medium and heavy-duty trucks until an EPA waiver is obtained. The failure to obtain a waiver repealed CARB’s ability to enforce ACF requirements on private‑sector fleets. Final action on the repeal is required by August 2026. It remains unclear whether CARB may reintroduce similar regulations in the future.

Food and Drug Administration.

As a transportation provider of foodstuffs, we are subject to rules and regulations issued by the Food and Drug Administration (FDA) to provide for the security of food and foodstuffs throughout the supply chain. The FDA has issued a final rule to establish certain requirements under the Sanitary Food and Transportation Act (SFTA) for vehicles and transportation equipment, transportation operations, training, recordkeeping and waivers. The rule is designed to promote best practices in the industry concerning cleaning, inspection, maintenance, loading and unloading of, and operation of vehicles. Under the SFTA requirements, carriers are required to develop and implement written procedures subject to recordkeeping that specify their practices for cleaning, sanitizing, and inspecting vehicles and transportation equipment.

Data Privacy Regulations.

We are subject to laws and regulations regarding data protection and transparency in how data is used and stored in the U.S. and other countries. As a transportation and logistics provider, we collect and process significant amounts of data daily.

Trademarks and Patents

We have registered several service marks and trademarks in the United States Patent and Trademark Office, including Saia Guaranteed Select®, Saia Customer Service Indicators® and Saia Xtreme Guarantee®. We believe these service marks and trademarks are important components of our marketing strategy.

Item 1A. Risk Factors

Certain factors may have a material adverse effect on our business, financial condition, and results of operations. You should carefully consider the risks and uncertainties described below, together with all the other information included in this Annual Report on Form 10-K, including our financial statements and the related notes. Our business, financial condition, operating results, cash flow and prospects could be materially and adversely affected by any of these risks or uncertainties. The risks below are organized by headings and each risk
is discussed separately, but many are interrelated. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of or that we currently see as immaterial may also adversely affect our business. Some statements in this Annual Report on Form 10-K, including statements in the following risk factors, constitute forward-looking statements. Please refer to “Cautionary Note Regarding Forward-Looking Statements.”

Industry and Economic Risks

We are subject to general economic conditions, any of which could adversely affect our business.

Our business is subject to a number of general economic conditions that may have a material adverse effect on our financial condition, results of operations, liquidity and cash flows. These conditions include recessionary economic cycles and downturns in customer business cycles, labor and supply shortages, global uncertainty and instability, inflation, changes in U.S. social, political, and regulatory conditions, tariffs and international trade
policies and relations, and disruptions in oil and financial markets. Economic conditions may adversely affect the business levels of our customers, their demand for transportation services, their ability to pay for our services, and could reduce the prices we are able to charge for our services.

We operate in a highly competitive industry and our business will be adversely impacted if we are unable to adequately address competitive pressures, such as industry consolidation, new competitors in the market, potential downward pricing pressures and other factors.

Numerous competitive factors could reduce our revenues, profit margins or market share or otherwise impair our business, any one of which may materially adversely affect our financial condition, results of operations, liquidity and cash flows. These factors include:

•

Competition with many other transportation service providers of varying types including LTL carriers, truckload and parcel carriers, non-asset based logistics, freight brokerage companies, air-freight carriers and railroads, some of whom have more equipment, a broader coverage network, a wider range of services and greater capital resources than we do or have other competitive advantages;

•

Transportation companies periodically reduce their prices to gain business, especially during economic recessions or times of reduced growth rates in the economy, which may limit our ability to maintain or increase prices or grow our business;

•

Many customers reduce the number of carriers they use by selecting approved transportation service providers, periodically accepting bids from multiple carriers for their shipping needs, or by developing their own or using alternative delivery mechanisms, and these practices may depress prices or result in the loss of business;

•

The trend towards consolidation in the surface transportation industry may create other large carriers with greater financial resources than us and other competitive advantages due to their size;

•

Disruptive technologies, including driverless trucks, electric vehicles, alternative fuels, artificial intelligence (AI) applications and software applications to monitor supply and demand may significantly alter historical business models of the trucking industry, potentially leading to increased capital expenditures and emergence of new competitors, some of whom may have greater financial resources than us and other advantages due to their size;

•

Large business enterprises, including e-commerce companies, with greater financial resources than us and other competitive advantages due to their size, have made or could make in the future investments that could enable them to enter into and compete with us in the LTL market;

•

The trend toward increased sales in the e-commerce sector as opposed to the traditional brick and mortar store model could threaten the continued operation of our retail customers, which could reduce the demand for our services and adversely impact our revenues; and

•

Technological advances require increased investments to remain competitive, and we may not utilize sufficient advanced technology, select the correct technology solutions or persuade our customers to accept higher prices to offset these investment costs.

The transportation industry is affected by business risks that are largely out of our control.

Businesses operating in the transportation industry are subject to risks that are largely out of our control. These risks include the health of the economy, weather and other seasonal factors, excess capacity in the transportation industry, supply chain disruptions, labor shortages, strikes or disruptions involving U.S. or international ports, decline in U.S. manufacturing, the impact of new or higher tariffs, armed conflicts, acts of terrorism and the government’s subsequent response, health epidemics, interest rates, inflation, fuel costs, taxes, license and registration fees, healthcare costs, insurance premiums and coverage availability. These risks, among others, may materially adversely affect our financial condition, results of operations, liquidity and cash flows.

We are dependent on cost and availability of qualified employees and purchased transportation.

There is significant competition for qualified drivers within the trucking industry and attracting and retaining qualified drivers has become more challenging due to a decreasing pool of qualified drivers and high turnover rates. Age demographics, hours of service rules, the legalization and growing recreational use of marijuana and regulatory requirements, including the Compliance Safety Accountability program and the Commercial Driver’s License Drug and Alcohol Clearinghouse of the Federal Motor Carrier Safety Administration (FMCSA), have contributed to the reduction in the number of eligible drivers and may continue to do so in the future.

Pursuant to an executive order in April 2025, the FMCSA updated its “out-of-service” criteria strengthening the enforcement of English language proficiency requirements for commercial drivers. Pursuant to the updated criteria, law enforcement must forbid a driver from operating a commercial vehicle if the driver fails a two-part interview and road sign test. In September 2025, the U.S. Department of Transportation (DOT) and the FMCSA issued a regulation strengthening the requirements for obtaining and renewing non-domiciled commercial driver licenses (CDLs). The regulation also directs state licensing agencies to revoke unlawfully issued non-domiciled CDLs. Increased enforcement of English language proficiency requirements for commercial drivers and regulatory efforts targeting unlawfully issued CDLs have further reduced the number of eligible commercial drivers and may continue to do so in the future and may lead to higher wages to attract qualified commercial drivers.

Moreover, as a result of general macroeconomic factors and the competitive labor market, we are experiencing difficulty hiring sufficient qualified employees to fill all available positions, including qualified drivers. The labor shortage is not limited to qualified drivers and at times, we have been unable to hire qualified dockworkers, mechanics and office personnel. We may experience shortages of qualified employees that could result in the failure to meet customer demands, upward pressure on wages and benefits, underutilization of our truck fleet and/or use of higher cost purchased transportation, any of which could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

Our operating and growth strategy depends on our ability to maintain adequate capacity throughout our service network, and we rely on purchased transportation to meet these needs. There is significant competition for quality purchased transportation within the trucking industry. We periodically experience shortages of quality purchased transportation that could result in higher costs for these services or prevent us from meeting customer demands which could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

Inflation may increase our expenses and lower profitability.

Inflation has been significant in the United States in recent years. Inflation increases most of our expenses, including equipment prices, maintenance and supply costs, diesel fuel costs, insurance costs, claims costs, utility costs, employee wages and benefits, healthcare costs, real estate costs, and purchased transportation. With increasing costs, we may have to increase our prices to maintain the same level of profitability. If we are unable to increase our prices sufficiently to offset increasing expenses, our financial condition, results of operations, liquidity and cash flows may be adversely affected.

We are dependent on the cost and availability of diesel fuel and on fuel surcharges.

Diesel fuel is a significant operating expense, and its availability is vital to daily operations. We do not hedge against the risk of diesel fuel price increases. General economic conditions, global political events, armed conflicts, acts of terrorism, cybersecurity incidents, inflation, tariffs, federal, state and local laws and regulations, world supply and demand imbalances, changes in refining capacity, public and investor sentiment, natural or man-made disasters, adverse weather conditions and other external factors could adversely affect the cost and availability of diesel fuel. In the past, we have secured diesel fuel from various sources and in the desired quantities, but there can be no assurance that this will continue to be the case in the future. Any shortage or interruption in the supply or distribution of diesel fuel could materially affect our financial condition, results of operations, liquidity and cash flows.

To the extent not offset by diesel fuel surcharges or other customer price changes, volatility in diesel fuel prices could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows. Historically, we have been able to offset significant diesel fuel price volatility through fuel surcharges and other pricing adjustments but we may not be able to do so in the future. Fluctuations in our diesel fuel surcharge recovery may result in fluctuations in our revenue. Rapid and significant fluctuations in diesel fuel prices could reduce our profitability unless we are able to make the appropriate adjustments to our pricing strategy. Such fluctuations could materially adversely affect our financial condition, results of operations, liquidity and cash flows.

Business and Operational Risks

Ongoing insurance and claims expenses could materially reduce and cause volatility in our earnings.

We are regularly subject to claims resulting from personal injury, cargo loss, property damage, group healthcare and workers’ compensation claims. The Company is self-insured for portions of medical, workers’ compensation, auto liability, casualty and cargo claims. We maintain insurance with licensed insurance companies above these self-insured retention limits. The trucking business has experienced significant increases in the cost of liability insurance, in the size of jury verdicts in personal injury cases arising from trucking accidents and in the cost of settling such claims. If the number or severity of these claims continues to increase, claims expenses might exceed historical levels or could exceed the amounts of our insurance coverage or the amount of our reserves for self-insured claims, which could materially adversely affect our financial condition, results of operations, liquidity and cash flows.

The Company is dependent on a limited number of third-party insurance companies to provide insurance coverage in excess of our self-insured retention amounts. In recent years, several insurance companies have completely stopped offering coverage to trucking companies, have significantly reduced the amount of coverage they offer or have significantly raised premiums as a result of increases in the severity of automobile liability claims and sharply higher costs of settlements and verdicts. To the extent that the third-party insurance companies propose increases to their premiums for coverage of commercial trucking claims, the Company may decide to pay such increased premiums or increase its financial exposure on an aggregate or per occurrence basis, including by increasing the amount of its self-insured retention or reducing the amount of total coverage. This trend could adversely affect our ability to obtain suitable insurance coverage, could significantly increase our cost for obtaining such coverage, or could subject us to significant liabilities for which no insurance coverage is in place, which could materially adversely affect our financial condition, results of operations, liquidity and cash flows.

Our self-insured retention limits can make our insurance and claims expenses higher and/or more volatile. We accrue for the estimated costs of the uninsured portion of pending claims based on the nature and severity of individual claims and historical claims development trends. Estimating the number and severity of claims, as well as related judgment or settlement amounts, is inherently difficult. This, along with legal expenses associated with claims, incurred but not reported claims, and other uncertainties can cause unfavorable differences between actual self-insurance costs and our reserve estimates.

To the extent the Company incurs one or more significant claims not covered by insurance, either because the claims are within our self-insured layer or because they exceed our total insurance coverage, our financial condition, results of operations, and liquidity could be materially and adversely affected.

Furthermore, insurance companies, as well as certain states, require collateral in the form of letters of credit or surety bonds for the estimated exposure of claims within our self-insured retentions. Their estimates of our future exposure as well as external market conditions could influence the amount and costs of letters of credit or surety bonds required under our insurance programs and thereby reduce capital available for future growth or adversely affect our financial condition, results of operations, liquidity and cash flows.

We face risks related to our geographic and network expansion.

We have implemented a strategy to significantly expand our geographic and terminal network. Consistent with our growth strategy, we have recently opened numerous new terminals in new and existing markets, and we intend to continue this terminal network growth in the future. There can be no assurance that we will be successful at adding new markets or terminals as planned, or that such markets or terminals will be profitable. Our expansion has required and will continue to require, significant investments in purchased or leased terminals, equipment (including the purchase of new tractors and trailers), technology, employees and other related start-up costs to facilitate our growth plans. Expansion could cause disruptions in our existing geography or customer service levels or require management to devote excessive time and effort to manage the expansion, which could materially adversely affect our business operations and profitability. Operating in new geographies may also increase the possibility of union organizing efforts. A delay between the outlay of expenditures to expand our geographic and network footprint and generation of new revenue or higher than anticipated costs or lower than expected revenues from the expansion could negatively impact our business. We may experience decreased profitability until we are able to fully realize the benefits of the investment, if ever. A failure or delay in realizing the benefits of this investment may adversely impact our financial condition, results of operations, liquidity and cash flows.

We face risks related to our purchase of certain real estate assets.

In January 2024, we acquired 17 freight terminals and leases to operate an additional 11 freight terminals pursuant to a sale by Yellow Corporation under Sections 363 and 365 of Chapter 11 of Title 11 of the U.S. Code. In connection with this acquisition, we assumed certain liabilities related to those facilities, including assumption of liabilities relating to environmental, health and safety matters in connection with the ownership, operation, use or maintenance of such facilities, to the extent not extinguished by the proceedings of the U.S. Bankruptcy Court for the District of Delaware. Since January 2024, we have also acquired additional facilities by assuming certain Yellow Corporation leases. We acquired these real estate assets on an as-is basis and could incur costs and expenses related to these assets that are unexpected or that exceed costs and expenses otherwise known. Moreover, from time to time we acquire real estate previously utilized by other freight companies or located in industrial areas, which may have a history of environmental contamination prior to our occupation. Failure to detect prior environmental contamination or adequately protect ourselves from associated liabilities could adversely affect our financial condition, results of operations, liquidity and cash flows. There can be no assurance that the Company will achieve the expected financial benefits of the acquisition of such assets.

We rely heavily on technology to operate our business, including through the use of third-party applications, and cybersecurity threats or other disruptions to our technology infrastructure could harm our business or reputation.

Our ability to attract and retain customers and compete effectively depends upon the reliability of our technology systems and network. Our cybersecurity and technology infrastructure includes technology products and services provided to us for use in our business by third party providers such as software as a service and cloud-based products and services. These third parties may store or transmit our data and may have access to information regarding our business operations, customers, and employees. Our technology systems, including any third-party applications, are constantly subject to attacks and efforts by outsiders to breach or gain access to our systems. Any disruption, failure or breach to our cybersecurity processes, technology controls or information technology infrastructure, including those impacting our computer systems and website, could adversely impact our customer service and revenues and result in increased risk of litigation or other costs. Our cybersecurity and technology infrastructure may experience errors, interruptions, failures, delays or damage from a number of causes outside of our control, including power and internet outages, hardware, software and network failures, computer viruses, malware or other destructive software, internal

design, manual or usage errors, cyber-attacks, terrorism, workplace violence or wrongdoing, catastrophic events, natural disasters and severe weather conditions. While we have invested and continue to invest in technology security initiatives and disaster recovery plans, these measures cannot fully protect us from technology disruptions that could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

Our dependence on electronic data storage, cloud-based systems, automated systems and technology, including our website, gives rise to cybersecurity risks. The techniques used to obtain unauthorized access or to disable or degrade systems change frequently, have become increasingly more complex and sophisticated and may be difficult to detect for a period of time and we may not be able to anticipate these acts or respond adequately or timely. Further, the evolution and increased adoption of technologies such as artificial intelligence and machine learning may make anticipating threats and implementing protective measures more difficult. We currently maintain insurance to address certain costs associated with cyber incidents and data privacy-related concerns. However, we cannot ensure that we will continue to maintain such insurance coverage in amounts we deem sufficient, that our insurance carriers will pay on our insurance claims, or that we will not experience uncovered claims. A security breach of our systems or those of our third-party providers may cause a disruption of our business, impact our ability to attract, retain and service customers, damage our reputation and brand, expose us to a loss of information or to a demand for payment of ransom or result in litigation, violations of applicable privacy and other laws, and regulatory scrutiny, investigations, actions, fines or penalties, any of which could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

Some of Saia’s employees work remotely, which may increase our exposure to cybersecurity risks, including phishing attempts and other cybersecurity attacks and may increase the demand for information technology resources.

A portion of our workforce operates remotely full-time or under hybrid work arrangements, and we provide these employees with expanded remote network access options to enable them to work outside of our buildings and, in some cases, on their own personal devices, which exposes us to increased cybersecurity risks. Such risks include: (i) unauthorized access to sensitive or confidential information due to company or personal devices being used to remotely access, discuss, or transmit confidential information, (ii) increased exposure to social engineering attempts such as phishing and other scams as cybercriminals may, among other things, install malicious software on systems and equipment and access sensitive or confidential information, (iii) increased demand for information technology resources, and (iv) violation of international, federal, or state-specific privacy laws. Although we have measures in place designed to mitigate our exposure to the increased risk of cybersecurity incidents, we cannot ensure that such measures will effectively prevent a cybersecurity incident. Further, as artificial intelligence technology continues to evolve, cybersecurity attacks leveraging artificial intelligence may become more sophisticated, potentially increasing in speed, scale and automation. Though we currently maintain property and cyber insurance, losses due to cybersecurity incidents may not be covered by insurance or may exceed our insurance coverage and may have a material adverse impact on our financial condition, results of operations, liquidity and cash flows.

A failure to keep pace with developments in technology could impair our operations or competitive position.

Our business relies on sophisticated systems and technology to remain competitive. Systems and technologies must be refined, updated and replaced with more advanced systems regularly for us to meet both internal requirements as well as our customer demands and expectations. If we are unable to do so in a timely manner or within reasonable cost parameters, or if we are unable to appropriately and timely train our employees to operate any of these new systems, our business could suffer. We also may not achieve the benefits that we anticipate from any new system or technology and a failure to do so could result in higher than anticipated costs or could impair our results of operations.

Technology and new market entrants may also disrupt the way we and our competitors operate. We expect our customers to continue to demand more sophisticated systems and technology-driven solutions. If we do not pursue technological advances or engage in innovation, or if the new technology doesn’t yield the results we expect, we may be placed at a competitive disadvantage, lose customers, incur higher costs or fail to meet our growth strategy. A failure to successfully pursue technological advances, including artificial intelligence applications could have a material adverse impact on our financial condition, results of operations, liquidity and cash flows.

We use artificial intelligence in our business, and its use could result in increased costs, reputational harm, competitive harm, cybersecurity risks and legal liability, which could have a material adverse effect on our business.

We incorporate certain artificial intelligence solutions into our business operations, and these applications may become more important in our operations over time. Our competitors or other third parties may incorporate artificial intelligence into their operations more quickly or more successfully than us, which could impair our ability to compete effectively and adversely affect our results of operations. To remain competitive, we may need to increase our investment in artificial intelligence solutions, and we may not be able to adjust pricing to offset the higher costs. Additionally, if the content, analyses, or recommendations that artificial intelligence applications assist in producing are, or are alleged to be, deficient, inaccurate or biased or to violate intellectual property rights of third parties, our financial condition, results of operations, liquidity and cash flows may be adversely affected.

The rapid evolution of artificial intelligence may result in increased cybersecurity incidents. Any such cybersecurity incidents could adversely affect our reputation and results of operations. Artificial intelligence also presents emerging ethical issues and if our use of artificial intelligence becomes controversial, we may experience brand or reputational harm, competitive harm, or legal liability. The rapid evolution of artificial intelligence, including potential government regulation of artificial intelligence and increased cybersecurity risks, will require significant resources to develop, test, implement and maintain our information technology systems to minimize unintended harmful impacts. The failure to effectively utilize artificial intelligence or to respond to cybersecurity threats from the use of artificial intelligence could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

Employees of Saia are non-union. The ability of Saia to compete could be impaired if operations were to become unionized.

None of our employees are currently subject to a collective bargaining agreement. We have in the past been the subject of unionization efforts which have been defeated. Our expansion into new geographic territory and our acquisition of additional terminals previously operated by Yellow Corporation and its subsidiaries could increase our overall risk of unionization. There can be no assurance that further unionization efforts will not occur in the future and that such efforts will be defeated. The unionization of our employees could lead to restrictive work rules that could hamper our efforts to improve and sustain operating efficiency and impair our service reputation. A strike or work stoppage could negatively impact our profitability and could damage customer and employee relationships. As such, customers may limit their use of unionized trucking companies because of the threat of strikes and other work stoppages. Unionization of any of our operations could lead to pressure on other employee sectors to unionize. Additionally, an election and bargaining process could divert management’s time and attention from our overall objectives and impose significant expenses. The non-union status of Saia is an important factor in our ability to compete in our markets, and if all or a portion of our workforce becomes unionized it could increase our costs and subject us to workplace rules, which could have a material adverse impact on our financial condition, results of operations, liquidity and cash flows.

The price of new and used revenue equipment may adversely affect our business operations.

Investment in new revenue equipment, including tractors and trailers, is a significant part of our annual capital expenditures. The price of such equipment may increase as a result of inflation, new or higher tariffs, increased demand for or decreased supply of such equipment, increased cost of materials and labor or because of current or future regulations on newly manufactured tractors, such as regulations issued by the Environmental Protection Agency (EPA) and by various state agencies, particularly the California Air Resources Board (CARB), requiring progressive reductions in exhaust emissions and a transition to zero-emission vehicles. Current regulations have increased prices for tractors and maintenance costs and may continue to do so in the future. In addition, as we purchase new revenue equipment as part of our normal replacement cycle each year, we rely on the used equipment market to dispose of our older equipment. Oversupply in the transportation industry, higher maintenance or operating costs associated with older equipment, as well as adverse economic conditions, can negatively impact the demand for used equipment and, therefore, reduce the value we can obtain for our used equipment. If we are unable to sell our used equipment at or above our salvage value, the resulting losses could have a material adverse impact on our financial condition, results of operations, liquidity and cash flows.

Higher costs for or limitations in the availability of suitable real estate have adversely affected and may continue to adversely affect our business operations.

Our business model is dependent on the cost and availability of terminal facilities. We have experienced higher costs to purchase, lease, build and/or refurbish terminal facilities as a result of inflation and higher demand for and reduced supply of such facilities. Shortages in the availability of suitable real estate or delays in obtaining necessary permits or approvals may result in significant additional costs to purchase, lease, build and/or refurbish necessary facilities, increase our capital expenditures and operating expenses, reduce our revenues, restrict our ability to grow existing markets or expand into new markets and/or prevent us from efficiently serving certain markets. In addition, we may not realize sufficient revenues or profits from our infrastructure investments. These higher costs and limitations in the availability of suitable real estate may adversely affect our financial condition, results of operations, liquidity and cash flows.

Supply chain disruptions could delay equipment deliveries and could increase costs or reduce operating capacity or expansion.

We do not manufacture any of the equipment or technology hardware used in our business. Tractors and trailers are important sources of capacity for our network operations and network expansion. The production of tractors and trailers could be impacted by manufacturing and component delays and other supply chain disruptions. We could be unable to obtain, or incur delays in the delivery of, equipment necessary for operations, including tractors, trailers and other equipment, as a result of manufacturing delays and supply chain disruptions. These manufacturing delays, supply chain disruptions and shortages could negatively affect our operations, increase our costs and impede our ability to grow and meet customer demand.

Changes in U.S. trade policy and the impact of tariffs may continue to adversely impact our customers, our industry, and our business.

We transport a significant number of shipments that have either been imported into the U.S. or are destined for export from the U.S. The U.S. government has made significant changes in U.S. trade policy, including the imposition of a baseline tariff on product imports from almost all countries and the potential for higher tariffs on certain other countries. Certain foreign governments either have taken or are threatening to take retaliatory actions in response. These changes in U.S. trade policy and tariffs have decreased demand for our services and have caused uncertainty and volatility in financial markets. Tariffs or other trade restrictions may lead to continuing uncertainty and volatility in U.S. and global financial and economic conditions, declining consumer confidence, inflation or an economic slowdown. These tariffs or other trade restrictions, including corresponding actions taken by other countries in response to U.S. governmental actions or continuing uncertainty around the timing or scale of tariffs, could continue to decrease demand for our services or could increase the cost to us of equipment, goods and materials used in our business, which could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

Capacity and infrastructure constraints could adversely affect service and operating efficiency.

We may experience capacity constraints due to increased demand for transportation services and decaying highway and energy infrastructure. Poor infrastructure conditions and roadway congestion could slow service times, reduce our operating efficiency and increase maintenance expenses. Some states have taken infrastructure funding measures into their own hands and have explored or instituted road-usage programs, truck-only tolling, congestion pricing, and fuel tax increases. Infrastructure constraints and measures to fund infrastructure improvements could materially adversely affect our financial condition, results of operations, liquidity and cash flows.

We face risks arising from our international business operations and relationships.

We are subject to the requirements of the Foreign Corrupt Practices Act of 1977 (FCPA) for our transportation and logistics services to and from various international locations. Failure to comply with the FCPA may result in legal claims against us or subject us to substantial fines. In addition, we face other risks associated with international operations and relationships, which may include restrictive trade policies, anti-corruption law enforcement, the renegotiation of international trade agreements, and imposition of duties, tariffs, taxes or government royalties imposed by domestic or foreign governments, any of which could materially adversely affect our financial condition, results of operations, liquidity and cash flows.

Our results of operations may be affected by seasonal factors, harsh weather conditions and disasters caused by climate change.

Our operations are subject to seasonal trends and fluctuations common in the transportation industry, which can impact our business in one or more quarterly periods. Severe weather events and natural disasters, such as blizzards, floods, wildfires, hurricanes, tornadoes, storms and earthquakes, could adversely impact our performance by disrupting our operations, damaging or destroying our equipment and facilities, increasing operating and maintenance costs, increasing insurance premiums and reducing the demand for our services. Climate change may increase the severity or frequency of extreme weather conditions and disasters. The Company has previously experienced severe weather events, including hurricanes, floods, wildfires, storms and snowstorms. Similar events in the future could disrupt our facilities or operations. The impact of severe weather events and natural disasters, including those caused by climate change, could materially adversely affect our financial condition, results of operations, liquidity and cash flows.

We face risks related to the creditworthiness of our customers or other business partners and their ability to pay for services.

If one or more of our customers experiences financial difficulties, including filing for bankruptcy, it may negatively affect our business due to the decreased demand for our services from these customers, or the potential inability of these companies to make full payment on amounts owed to us. Customer bankruptcies also entail the risk of potential recovery by the bankruptcy estate of amounts previously paid to us that are deemed a preference under bankruptcy laws. We do not carry insurance against the risk of customer default on their payment obligations to us or against bankruptcy preference claims. The risks associated with these matters will likely increase in the event of an economic downturn. The loss of revenue from these customers or payment of preference claims could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

We have significant ongoing cash requirements that could limit our growth and affect profitability if we are unable to generate sufficient cash from operations or obtain sufficient financing on favorable terms.

Our business is highly capital intensive. Our net capital expenditures for 2025 were approximately $544 million and we anticipate net capital expenditures in 2026 of approximately $350 million to $400 million, subject to the ongoing evaluation of market conditions. We depend on cash flows from operations, borrowings under our credit facilities and operating and finance leases. If we are unable to generate sufficient cash from operations and obtain sufficient financing on favorable terms in the future, we may have to limit our growth, enter into more restrictive or higher cost financing arrangements or operate our tractors and trailers for longer periods prior to replacement, possibly increasing maintenance costs, any of which could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

Our credit agreements contain financial and other restrictive covenants and we may be unable to comply with these covenants. A default could cause a material adverse effect on our business.

We must satisfy certain financial and other restrictive covenants under our credit agreements, including among others, a maximum consolidated net lease adjusted leverage ratio, as defined in our credit agreements. If we fail to comply with any of the covenants under our credit agreements, we will be in default under the agreements which could cause cross-defaults under other financial arrangements. In the event of any such default, if we fail to obtain replacement financing or amendments to or waivers under the financing arrangement, our financing sources could

cease making further advances, cease issuing letters of credit required under our insurance programs and declare our debt to be immediately due and payable. If acceleration occurs, we may have difficulty borrowing sufficient additional funds to refinance the accelerated debt or obtain required letters of credit, or we may need to issue securities which would dilute stock ownership. Even if new financing is made available to us, the terms may not be acceptable. A default under our credit agreements could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

We are required to make significant estimates and assumptions in the preparation of our financial statements. These estimates and assumptions may not be accurate and are subject to change. Our internal controls over financial reporting may not prevent or detect all misstatements in our financial statements.

The preparation of our consolidated financial statements in conformity with U.S. generally accepted accounting principles requires our management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent liabilities at the date of the consolidated financial statements, and the reported amounts of income and expense during the reported periods. Our internal controls over financial reporting provide reasonable, not absolute, assurance of accurate financial statements and may not prevent or detect misstatements due to inherent limitations such as human error, information technology system failures, or fraud. Inadequate internal controls or incorrect underlying estimates and assumptions or events that require us to revise our previous estimates or assumptions could have a material adverse effect on our financial condition and results of operations.

If we are unable to retain our key employees, our business could be materially adversely impacted.

We depend on the efforts and abilities of our management, and we believe their knowledge would be difficult to replicate. Our success is dependent on our ability to retain our current management team and to recruit, hire, develop and retain highly qualified personnel in the future. Competition for key management is intense, and qualified individuals are in high demand, such that we may incur significant costs to attract and retain them. Other than our Chief Executive Officer, members of our management team do not have employment agreements. Certain of our key employees are subject to non-compete and non-solicitation agreements; however, there is no assurance that such agreements will be enforced as written or that they will be effective to prevent those employees from working for a competitor or soliciting our customers. The loss of the services of any of our key employees could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows. Inadequate succession planning or the unexpected departure of a key employee would require our remaining management team to divert immediate and substantial attention to fulfilling the duties of the departing employee and to seeking a replacement. The inability to adequately fill vacancies on a timely basis could negatively affect our ability to implement our business strategy and thus materially adversely affect our financial condition, results of operations, liquidity and cash flows.

Changes to our compensation and benefits could adversely affect our ability to attract and retain qualified employees.

The compensation we offer our employees is subject to market conditions that may require increases in employee compensation and benefits, which becomes more likely as a result of higher inflation and as economic conditions improve. We may experience unusual employee turnover by our drivers, dockworkers, maintenance employees and other personnel that would result in operational deterioration. If we are unable to attract and retain enough qualified employees, we could be required to increase our compensation and benefits packages, amend our hiring standards or reduce our operations and face difficulty meeting customer demands, any of which could materially adversely affect our financial condition, results of operations, liquidity and cash flows.

An increase in the cost of healthcare benefits could have a negative impact on our business.

We maintain and sponsor competitive health insurance and other benefits for our employees and their dependents to attract and retain our employees. We have incurred higher costs for these benefits, and it is possible that healthcare benefits and administration costs could become cost prohibitive, forcing us to either reduce our benefits program (making it more difficult to attract and retain qualified employees) or pay the higher costs. Either outcome could materially adversely impact our financial condition, results of operations, liquidity and cash flows.

Our business depends in part on our strong reputation.

We believe that our corporate reputation and the positive image of our brand are valuable assets. As social media usage increases, our susceptibility to risks related to adverse publicity, whether or not justified, increases. Adverse publicity regarding labor relations, legal matters, cybersecurity and data privacy events, truck accidents, cargo theft, environmental issues and similar matters, even when based on erroneous information, could have a negative impact on our reputation and may result in the loss of customers and our inability to secure new customer relationships. The immediacy of certain social media outlets precludes us from having real-time control over postings related to the Company, whether matters of fact or opinion. Information distributed via social media could result in immediate unfavorable publicity that we do not have the ability to reverse. Unfavorable publicity, regardless of its cause or source, could result in damage to our reputation and adversely impact our financial condition, results of operations, liquidity and cash flows.

Our acquisitions may be unsuccessful or result in other risks such as the failure to realize the anticipated benefits of such acquisitions or the disruption of our business due to such acquisitions.

We may acquire additional businesses and operations in the future. However, there is no assurance that we will be successful in identifying, negotiating, consummating or integrating any future acquisitions. Additionally, we may not realize the anticipated benefits of any future acquisitions. Each acquisition has numerous risks including:

•

Difficulty in integrating the operations and personnel of the acquired company or unanticipated costs to support new business lines or separate legal entities;

•

Unanticipated issues in the assimilation and consolidation of information technology, communications, and other systems, including additional systems training and other labor inefficiencies;

•

Disruption of our ongoing business, distraction of our management and employees from other opportunities and challenges due to integration issues;

•

Additional indebtedness or the issuance of additional equity to finance future acquisitions, which could be dilutive to our stockholders;

•

Potential loss of key customers or employees of acquired companies along with the risk of unionization of employees;

•

Reductions in prices we charge certain customers in order to match existing customer pricing in the acquired company’s markets;

•

Inability to achieve the financial and strategic goals for the acquired and combined businesses;

•

Potential impairment of tangible and intangible assets and goodwill acquired as a result of acquisitions; and

•

Potential failure of the due diligence processes to identify significant issues with legal, financial, or environmental liabilities and contingencies, among other things.

In the event that we do not realize the anticipated benefits of an acquisition, if we incur unexpected liabilities with an acquisition, or if the acquired business is not successfully integrated, there could be a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

Litigation and Regulatory Risks

We face litigation risks that could have a material adverse effect on the operation of our business.

We face litigation risks regarding a variety of issues, including accidents involving our trucks and employees, workers’ compensation claims, federal and state labor and employment law claims, securities claims, privacy claims, contract claims, environmental liability and other matters. These proceedings may be time-consuming, expensive and disruptive to normal business operations. The defense, settlement or resolution of such matters could result in significant expense and the diversion of our management’s time and attention from the operation of our business. In recent years, several insurance companies have completely stopped offering coverage to trucking companies for automobile liability claims, have significantly reduced the amount of coverage they offer or have significantly raised

premiums as a result of increases in the severity of automobile liability claims and sharply higher costs of settlements and verdicts. This trend could adversely affect our ability to obtain suitable insurance coverage, could significantly increase our cost of obtaining such coverage or could subject us to significant liabilities for which no insurance is in place, which could materially adversely affect our financial condition, results of operations, liquidity and cash flows. Costs we incur to defend or to satisfy a judgment or settle claims may not be covered by insurance or could exceed the amount of that coverage or increase our insurance costs and could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

The engines in our tractors are subject to emissions-control regulations that could substantially increase operating expenses, and regulations concerning emissions or fuel-efficiency may have a material adverse impact on our business.

Despite the current administration’s rollback of regulations at the federal level, emissions and fuel efficiency standards remain at the state level that could require significant changes in our business. Several states have enacted and may enact in the future legislation relating to engine emissions, trailer regulations, fuel economy, and/or fuel formulation, such as regulations issued by the California Air Resources Board (CARB). CARB regulations apply to both in-state California carriers and carriers outside of California who own or dispatch equipment in the state. CARB has adopted regulations to accelerate large-scale transition in California to zero-emission medium and heavy-duty trucks, including trucks of a type used in our operations in California.

Tractor engines that comply with emission-control regulatory requirements have generally been more expensive, less fuel-efficient and have increased maintenance costs. If we are unable to offset the higher costs associated with this equipment with higher freight rates or improved fuel economy, our financial condition, results of operations, liquidity and cash flows could be materially adversely affected.

At this point, there are virtually no zero-emissions vehicles widely available that are suitable replacements for current technology used in less-than-truckload operations. In addition, there does not appear to be sufficient infrastructure in place to support an electric vehicle fleet operation throughout our current terminal network. If zero-emission vehicles are not available or not commercially viable for the less-than-truckload market, we may be required to modify or curtail our operations in California or other states that have adopted or may adopt similar regulations. During any transition to zero-emission trucks, due to the mandates on manufacturers limiting diesel engine sales, we may be forced to continue using older model diesel trucks that may require higher maintenance costs or be less reliable. Compliance with EPA, CARB, and other federal and state regulations regarding the transition to utilizing zero-emission vehicles could increase our equipment costs and may have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

We operate in a highly regulated and highly taxed industry. Costs of compliance with or liability for violation of existing or future regulations may adversely affect our business.

The DOT and various state agencies exercise broad powers over our business, generally governing such activities as authorization to engage in motor carrier operations, safety and financial reporting. We may also become subject to new or more restrictive regulations imposed by the DOT, the Occupational Safety and Health Administration, the Food and Drug Administration or other authorities relating to engine exhaust emissions, safety performance and measurements, driver hours of service, immigration, drug and alcohol testing, food safety, security, ergonomics, as well as other unforeseen matters. Compliance with such regulations could substantially impair equipment productivity and increase our costs.

Taxes are a significant part of our annual expenses, and we are subject to various federal and state income, payroll, property, sales and other taxes. In addition, various federal and state authorities impose significant operating taxes on the transportation industry, including fuel taxes, tolls, excise and other taxes. There can be no assurance that such taxes will not substantially increase or that new or revised forms of operating taxes or tax laws or regulations, will not be imposed on the industry. Higher tax rates, claims, audits, investigations or legal proceedings involving taxing authorities could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

The FMCSA rules on motor carrier driver hours of service limit the maximum number of hours a driver may be on duty between mandatory off-duty hours and require driver rest breaks. These rules could result in us not meeting customer demands, upward pressure on driver wages and benefits, underutilization of our truck fleet and/or use of

higher cost purchased transportation which could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

The Company’s operations are subject to a variety of other federal, state and local laws and regulations, including labor and employment, wage and hour and employee benefit laws and regulations, tax, environmental, health and safety, data privacy, anti-trust and securities laws and regulations. Compliance with these laws and regulations is onerous and expensive. New and changing laws and regulations can adversely affect the Company’s business by increasing costs and requiring changes to the Company’s business. New and changing laws and regulations can also create uncertainty about how such laws and regulations will be interpreted and applied. There can be no assurance the Company’s employees, contractors or agents will not violate such laws and regulations or the Company’s policies and procedures. If the Company is found to have violated laws and regulations, it could materially adversely impact our financial condition, results of operations, liquidity and cash flows.

We may incur unforeseen costs from new and existing data privacy laws.

Our business is subject to increased legislative and regulatory efforts regarding data protection and transparency in how data is used and stored. State governments have enacted and may enact in the future data protection laws, such as the California Consumer Privacy Act of 2018 as amended and extended by the California Privacy Rights Act in 2020. The reporting requirements imposed by data protection and transparency laws may differ in scope and applicability and may result in conflicting obligations. As a transportation and logistics provider, we collect and process significant amounts of data daily. Monitoring and complying with data protection laws may increase our compliance costs or require alterations to our data handling practices. The increasing scope and complexity and the uncertainty of the interpretation and enforcement of these laws create legal risk. Violations or noncompliance with data protection laws could result in significant liability from governmental or civil actions and negative impacts to our reputation, financial condition, results of operations, liquidity and cash flows.

We are subject to various environmental laws and regulations. Costs of compliance with or liabilities for violations of existing or future environmental laws and regulations could have a material adverse effect on our business and operations.

Our operations are subject to environmental laws and regulations dealing with the handling of hazardous materials, underground fuel storage tanks and discharge and retention of storm water. We operate in industrial areas where truck terminals and other industrial activities are located and where groundwater or other forms of environmental contamination may have occurred. Under existing law, we could be held responsible for costs related to environmental contamination at, or emanating from, our current and past facilities and at third party waste disposal sites. Our operations involve the risks of fuel spillage or seepage, environmental damage and hazardous waste disposal and costs associated with the leakage or discharge of hazardous materials we transport for our customers, among others. Violations of applicable environmental laws or regulations or spills or other accidents involving hazardous substances have occurred in the past, can occur in the future, and may subject us to cleanup costs, liabilities not covered by insurance, substantial fines or penalties and to civil and criminal liability, any of which could materially adversely affect our financial condition, results of operations, liquidity and cash flows.

In addition, there is global scientific consensus that emissions of greenhouse gases (GHG) continue to alter the composition of Earth’s atmosphere in ways that are affecting, and are expected to continue to affect, the global climate. As these climate change concerns become more prevalent, federal, state and local governments and our customers are increasingly sensitive to these issues. Increased awareness and negative publicity regarding greenhouse gas emissions from transportation companies may damage our reputation and could reduce demand for our services. This increased focus may result in new legislation, taxes, regulations and customer requirements, such as limits on vehicle weight and size and restrictions on GHG emissions, which could negatively affect us. In addition, several states, including states where we conduct business, have adopted various GHG disclosure and reduction programs. The EPA and the states could also further regulate GHG emissions. These regulations could increase the costs of replacing and maintaining tractors, and cause us to incur additional taxes and operating costs and capital expenditures to make changes to our operations in order to comply with these regulations. The regulations could also cause delays or disruptions in our operations and could reduce our revenues. We are subject to increasing investor and customer sensitivity to sustainability issues, and we may be subject to additional requirements related to shareholder proposals, customer-led initiatives, or our customers’ efforts to comply with environmental programs. Until the timing, scope, and extent of any future regulation or customer requirements become known, we cannot predict their effect on our

cost structure, business, or results of operations. We could lose revenue if our customers divert business from us because we have not complied with their sustainability requirements. These costs, changes and loss of revenue could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

The Compliance Safety Accountability (CSA) program could adversely affect our results of operations and ability to maintain or grow our business.

The CSA program is an enforcement and compliance model required by the FMCSA that assesses a motor carrier’s on-road performance and investigation results for a 24-month period using roadside stops and inspections, resulting in safety and performance ratings.

The CSA program evaluations are used to rank carriers and individual drivers and to select carriers for audit and other interventions or enforcement action. If we receive unacceptable CSA program scores, our relationships with our customers or our reputation could be damaged, which could result in decreased demand for our services. The requirements of the CSA program could also shrink the industry’s pool of drivers as those with unfavorable scores could leave the industry. If the Company receives unacceptable CSA program scores or if the CSA program reduces the pool of drivers, our financial condition, results of operations, liquidity and cash flows may be adversely affected.

Our business may be adversely impacted by potential future changes in accounting and financial practices.

Future changes in accounting standards or practices, and related legal and regulatory interpretations of those changes, may adversely impact public companies in general, the transportation industry or our operations specifically. New accounting standards or requirements could change the way we record revenues, expenses, assets and/or liabilities or could be costly to implement. These types of standards, practices and regulations could have a material adverse impact on our financial position, results of operations, liquidity and cash flows.

Other Risks

Health epidemics, pandemics and similar outbreaks have had, and may continue to have, material adverse effects on the Company’s business, results of operations, financial condition and stock price.

Health epidemics, pandemics and similar outbreaks can have significant and widespread impacts, including material adverse impacts on demand for the Company’s services, the Company’s ability to execute its operating and strategic plans, the Company’s profitability and cost structure, and supply chain disruptions. The extent to which a health epidemic, pandemic or outbreak may impact the Company’s operational and financial performance is uncertain and will depend on many factors outside the Company’s control, including the timing, extent and duration of the health event, governmental responses to the event, the development, availability, effectiveness of vaccines or treatments, the imposition of protective public safety measures, and the impact of the outbreak on the global economy and demand for products and services.

The Company faces risks from international conflicts that could adversely impact our business and financial results.

International security concerns and conflicts, including those in Russia-Ukraine, Taiwan-China, in the Middle East, and other geopolitical tensions, and potential actions or retaliatory measures taken in respect thereof, have had and could continue to have a material adverse effect on global trade and economic activity. The consequences of such conflicts include embargoes, regional instability, supply chain disruptions, new or higher tariffs, disruptions of global financial markets, reduced access to oil and natural gas and higher energy prices. The extent of a conflict's effect on the global economy cannot be predicted, including the extent to which the conflict may heighten other risks disclosed herein. Ultimately, these or other factors associated with international conflicts could materially adversely affect our financial condition, results of operations, liquidity and cash flows.

We are subject to evolving and often contradictory stakeholder expectations regarding environmental and social issues and our failure to meet stakeholder expectations could impact the demand for our services or the price of our stock.

Companies across all industries, including Saia, are subject to increased scrutiny from stakeholders, including investors, customers, shareholder advocacy groups and governmental entities, concerning environmental matters, such as greenhouse gas emissions, and social issues, such as employment practices and civil rights. These expectations are often contradictory, are evolving and can be difficult to manage. If we are unable to meet these stakeholder expectations, our reputation could suffer resulting in a loss of revenues, we could face litigation or investors may choose not to invest in our stock resulting in a decline in our stock price.

A government shutdown or failure to fund government services could impact our operations.

Our business may be adversely impacted if federal government agencies close or operate at reduced staffing levels during a prolonged government shutdown. We are regulated by several federal agencies, including the Department of Transportation. Our business directly and indirectly relies on federal agencies for permitting, compliance reviews and driver background checks. During a shutdown, FMCSA databases may not be updated and carrier authority applications, safety audits, and compliance reviews can be delayed. State and local commercial driver’s license agencies rely on federal databases and coordination with the DOT. Understaffing or reduced activity at any of these agencies during a shutdown could disrupt our operations. We believe that the government shutdown that commenced on October 1, 2025, did not materially impact our operations; however, a future shutdown may materially impact our business operations.

Delays at major trade hubs and ports can impact demand for our services and the volume of freight in our network. Staffing shortages, or the failure of essential government employees to report for work, can slow freight crossing times at ports of entry. Moreover, if a shutdown results in a pause in disbursing government financial assistance, consumer spending could decrease, which could reduce customer demand for our services. Any government shutdown or failure to fund government services could materially affect our financial condition, results of operations, liquidity and cash flows.

Certain provisions of our governing documents and Delaware law could have anti-takeover effects.

As a Delaware corporation, we are subject to certain Delaware anti-takeover provisions. Under Delaware law, a corporation may not engage in a business combination with any holder of 15 percent or more of its capital stock unless the holder has held the stock for three years or, among other things, the Board of Directors has approved the transaction. Our Board of Directors could rely on Delaware law to prevent or delay an acquisition of the Company.

Our Restated Certificate of Incorporation and Bylaws contain certain provisions which may have the effect of delaying, deferring or preventing a change of control of the Company. Such provisions include, for example, a prohibition on stockholder action by written consent, authorization of the Board of Directors to issue preferred stock in series with the terms of each series to be fixed by the Board of Directors, limitations on who may call special stockholder meetings, and advance notice procedures for stockholder proposals and nominations to the Board of Directors. These provisions may inhibit fluctuations in the market price of our common stock that could result from takeover attempts.

If we raise additional capital in the future, our stockholders’ ownership in the Company could be diluted.

Any issuance of equity we may undertake in the future could cause the price of our common stock to decline or require us to issue shares at a price that is lower than that paid by holders of our common stock in the past, which would result in those newly issued shares being dilutive. If we obtain funds through a credit facility or through the issuance of debt or preferred securities, these obligations and securities would likely have rights senior to those of common stockholders, which could impair the value of our common stock.

Weakness or a loss of confidence in financial markets could adversely impact demand for our services or for our stock.

Weakness or a loss of confidence in the financial markets or an economic downturn could cause our share price to decline, could cause broader economic downturns, could lower demand for our services, decrease the price we can charge for our services, increase the incidence of customers’ inability to pay their accounts, or increase insolvency of our customers, any of which could materially adversely affect our financial condition, results of operations, liquidity and cash flows.

Disruptions in the credit markets, including in the availability and cost of short-term funds for liquidity and letter of credit requirements, may adversely affect our business and our ability to meet long-term commitments.

If internal funds are not available from our operations, we may be required to rely on the capital and credit markets to meet our financial commitments and short-term liquidity needs. Longer term disruptions in the capital and credit markets resulting from economic or political uncertainty, changing or increased regulation, significantly higher interest rates, reduced alternatives or failures of significant financial institutions, among other things, could adversely affect our access to or the cost of liquidity needed for our business. Any disruption could require us to take measures to conserve cash until the markets stabilize or until alternative credit arrangements or other funding for our business needs can be arranged. Such disruptions may have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.

The market value of our common stock may fluctuate and could be substantially affected by various factors.

The price of our common stock on the Nasdaq Global Select Market constantly changes. Such fluctuations may be unrelated to our financial performance. We expect that the market price of our common stock will continue to fluctuate due to a variety of factors, many of which are beyond our control. These factors include, but are not limited to:

•

Actual or anticipated variations in our earnings, financial or operating performance or liquidity, or those of other companies in our industry;

•

Changes in recommendations or projections of research analysts who follow our stock or the stock of other companies in our industry;

•

Failure to meet the earnings projections of research analysts who follow our stock;

•

Changes in general economic and capital market conditions, including general market price declines or market volatility;

•

Reactions to our regulatory filings and announcements related to our business;

•

Operating and stock performance of other companies in our industry;

•

Actions by government regulators;

•

Potential costs and liabilities associated with cyber events;

•

Widespread outbreak of an illness, any other communicable disease or public health crisis, and the government’s response thereto;

•

Litigation involving our company, our industry or both;

•

News reports or trends, concerns and other issues related to us or our industry; and

•

Other factors described in this “Risk Factors” section.

Our stock price, financial condition, results of operations, liquidity and cash flows could be materially adversely affected by an unfavorable outcome resulting from these risks and uncertainties.

Item 1B. Unresolved Staff Comments

None.

Item 1C. Cybersecurity

Cybersecurity risk management and strategy

Saia maintains cybersecurity processes, technologies and controls to help us assess, identify and manage material risks from cybersecurity threats. These processes, technologies and controls are part of Saia’s overall enterprise risk management process. Our cybersecurity program is based on the National Institute of Standards and Technology Cybersecurity Framework version 2.0, and the National Institute of Standards and Technology Artificial Intelligence Risk Management Framework. The Saia cybersecurity program is designed to ensure that our information systems are effective and are prepared for cybersecurity threats, including through regular oversight and mitigation of internal and external threats.

We regularly perform evaluations of our information security program and our information technology infrastructure, including through the use of tools and services for network and endpoint monitoring, vulnerability assessments and penetration testing, among other things. We have implemented security monitoring capabilities designed to alert us to suspicious activity and have an incident response program to restore business operations as quickly and as orderly as possible in the event of a cybersecurity incident.

Saia contracts with third party firms to evaluate our information security program, for continuous system monitoring and threat detection, to gather insights for identifying and assessing material cybersecurity threats, and for potential mitigation assistance. We consider cybersecurity matters when selecting and overseeing our third party service providers and we administer a standardized information gathering questionnaire to evaluate cybersecurity risk in third parties. We seek to require third parties who could pose significant cybersecurity risk to us to be contractually responsible for the risk and to agree to cybersecurity assessments in connection with new vendor engagements and annually thereafter.

Saia has an established cybersecurity and information security awareness training program that includes mandatory annual training and regular communications for our employees regarding cybersecurity threats and methods of mitigation. The annual cybersecurity training consists of threat avoidance when working remote, proper password construction techniques, identifying and reporting suspicious activity, social engineering and insider threats. Additionally, we have implemented a regular phishing assessment that provides feedback and additional training to enhance the annual training program. Our information technology professionals also receive additional training related to their position.

There can be no guarantee that our cybersecurity processes, technologies and controls will be effective. Although our risk factors include further detail about the material cybersecurity risks we face, including the evolving risks from artificial intelligence, we believe that risks from prior cybersecurity threats, including as a result of any previous cybersecurity incidents, have not materially affected our business to date. We can provide no assurance that there will not be cybersecurity incidents in the future or that they will not materially affect us, including our business strategy, results of operations or financial condition.

For more information about the cybersecurity risks we face, see the risk factors, including those entitled “We rely heavily on technology to operate our business, including through the use of third-party applications, and cybersecurity threats or other disruptions to our technology infrastructure could harm our business or reputation” and "We use artificial intelligence in our business, and its use could result in reputational harm, competitive harm, cybersecurity risks and legal liability, which could have a material adverse effect on our business" in Item 1A. Risk Factors.

Governance

Management is responsible for the day-to-day assessment and management of cybersecurity risks. Saia’s Director of Information Technology Security, who reports to the Executive Vice President and Chief Information Officer, has primary oversight of our cybersecurity risk management and strategy processes. The Director of

Information Technology Security has served in information security roles since 2001 and led the information security function for a large health care system prior to joining Saia in 2021. He has a Bachelor of Science degree in Information Technology with a Concentration in Information Assurance and Security.

The Director of Information Technology Security assesses our cybersecurity readiness through internal assessment tools as well as third-party control testing, vulnerability assessments and evaluation against industry standards. We maintain compliance structures that are designed to elevate issues relating to cybersecurity to our Director of Information Technology Security and to our Executive Vice President and Chief Information Officer.

The Board of Directors has oversight responsibility for Saia’s strategic and operational risks. Although the Board has delegated oversight responsibility for certain risks to its committees, the Board has determined that oversight for cybersecurity should remain with the full Board. The Board regularly receives reports from the Executive Vice President and Chief Information Officer concerning the Company’s cybersecurity risk management and strategies and related processes, technologies and controls.

Item 2. Properties

Saia is headquartered in Johns Creek, Georgia and has additional general offices in Houma, Louisiana and Boise, Idaho. At December 31, 2025, Saia owned 135 service facilities, including the Houma, Louisiana general office, and leased 82 service facilities, including the Johns Creek, Georgia corporate office, the Boise, Idaho general office and the Dallas, Texas warehouse. At December 31, 2025, Saia owned 62 percent of its service facilities, accounting for 72 percent of its door capacity. This mix follows Saia’s strategy of seeking to own strategically-located facilities that are integral to its operations and lease service facilities in smaller markets to allow for more flexibility. As of December 31, 2025, Saia owned approximately 7,700 tractors and 26,500 trailers, inclusive of trailers acquired with finance leases.

We are under no obligation, and we expressly disclaim any obligation, to update or alter any forward-looking statements, whether as a result of new information, future events or otherwise, except as otherwise required by applicable law.

Executive Overview

The Company’s business is closely correlated with non-service sectors of the general economy. Our strategy is to improve profitability by increasing revenue per shipment while growing shipment volumes. Components of this strategy include building density within our existing network and expanding our geographical footprint and terminal infrastructure to support profitable growth and strengthen our customer value proposition over time. The Company’s operations are labor intensive, capital intensive and service sensitive. We continuously seek opportunities to improve safety performance, cost efficiency and asset utilization - particularly with respect to tractors and trailers. Pricing initiatives have contributed positively to profitability. The Company continues to execute targeted sales and marketing programs along with actions designed to align our cost structure with volumes and improve customer satisfaction.

Technology continues to be an important investment as we work to improve the customer experience, advance operational efficiency and support the Company's brand and service quality.

The Company’s operating revenue increased by 0.8 percent in 2025 compared to 2024. The increase was a result of increased revenue per shipment, including fuel surcharge, due to pricing actions and truckload volume generated through our logistics business. Pricing actions, which included 5.9 and 7.9 percent general rate increases on October 1, 2025 and October 21, 2024, respectively, for customers subject to general rate increases, were largely offset by slightly lower shipment volumes.

Consolidated operating income decreased to $352.2 million for 2025 compared to $482.2 million in 2024. The decrease in 2025 operating income resulted primarily from increases in salaries, wages and benefits, including group health insurance costs, depreciation expense and claims and insurance costs. These increases were partially offset by increased revenue of $25.2 million, year over year.

The Company generated $595.0 million in net cash provided by operating activities in 2025 versus $583.7 million in 2024. The Company used $552.5 million of net cash in investing activities during 2025 compared to $1,035.9 million during 2024.

General

This Management’s Discussion and Analysis of Financial Condition and Results of Operations describes the principal factors affecting the results of operations, liquidity and capital resources, as well as the critical accounting policies of Saia, Inc. and its wholly-owned subsidiaries (together, the Company or Saia). This discussion should be read in conjunction with the accompanying audited consolidated financial statements which include additional information about our significant accounting policies, practices and the transactions that underlie our financial results.

Saia is a transportation company headquartered in Johns Creek, Georgia that provides less-than-truckload (LTL) services through a single integrated organization. While approximately 97% of its revenue is derived from transporting LTL shipments across the United States, the Company also offers customers a wide range of other value-added services, including brokered truckload and expedited transportation and other logistics services across North America.

Our business is closely correlated with non-service sectors of the general economy. Our business also is impacted by a number of other factors and risks as discussed under “Cautionary Note Regarding Forward-Looking Statements” and Part I, Item 1A., “Risk Factors.” The key factors that affect our operating results are the volumes of shipments transported through our network, as measured by our average daily shipments and tonnage; the prices we obtain for our services, as measured by revenue per shipment and revenue per hundredweight (a measure of yield), whether including or excluding fuel surcharge revenue; our ability to manage our cost structure for capital expenditures and operating expenses such as salaries, wages and benefits; purchased transportation; claims and insurance expense; fuel and maintenance; and our ability to match operating costs to shifting volume levels.

Year ended December 31, 2025 as compared to year ended December 31, 2024

Revenue and volume

Consolidated revenue increased 0.8 percent to $3.2 billion primarily due to increased revenue per shipment, including fuel surcharge, due to pricing actions and truckload volume generated through our logistics business. Positive pricing actions were largely offset by slightly lower shipment volumes. Saia’s LTL tonnage increased 2.1 percent while LTL shipments decreased 0.7 percent for 2025. Overall LTL revenue per shipment, excluding fuel surcharges, increased 1.2 percent in 2025 as a result of pricing actions. For 2025 and 2024, approximately 75 percent of Saia’s operating revenue was subject to specific customer price adjustment negotiations that occur throughout the year. The remaining 25 percent of operating revenue was subject to a general rate increase which is based on market conditions. For customers subject to general rate increases, Saia implemented 5.9 and 7.9 percent general rate increases on October 1, 2025 and October 21, 2024, respectively. Competitive dynamics, customer turnover and changes in shipment mix, among other things, may limit our ability to retain customer rate increases over time.

Operating revenue includes revenue from the Company’s fuel surcharge program. This program is designed to mitigate the Company’s exposure to volatility in diesel fuel prices by adjusting total freight charges to reflect changes in the national average diesel price. Fuel surcharges, which are typically updated weekly, are widely accepted within the LTL industry and represent a significant component of revenue and pricing structure. Although fuel surcharges are an important element of customer contract negotiations, they comprise only one aspect of total pricing, as customers may negotiate adjustments between base rates and fuel surcharges depending on individual contract terms. Fuel surcharge revenue remained flat at 15.0 percent of operating revenue in 2025 compared to 15.0 percent in 2024.

Operating expenses and margin

Consolidated operating income decreased to $352.2 million in 2025 compared to $482.2 million in 2024. The decrease in 2025 operating income resulted primarily from increases in salaries, wages and benefits, including group health insurance costs, depreciation expense and claims and insurance costs. These increases were partially offset by increased revenue of $25.2 million, year over year. The 2025 operating ratio (operating expenses divided by operating revenue) was 89.1 percent as compared to 85.0 percent in 2024.

Salaries, wages and employees’ benefits expense increased $91.9 million in 2025 compared to 2024. This increase was driven by increased group health insurance costs of $37.3 million related to the inflationary costs of claims. This increase also reflects Company-wide wage increases of approximately 3% in October 2025 and 4.1% in July 2024 for all employees other than executives as well as higher average head count associated with new terminal openings, most of which occurred during the first quarter of 2025. Purchased transportation expense decreased $2.7 million in 2025 compared to 2024 primarily due to a decrease in purchased transportation miles and decreased cost per mile for purchased transportation. Fuel, operating expenses and supplies increased by $25.3 million primarily driven by increased information technology costs associated with network optimization and support. This increase also reflects higher facility and vehicle maintenance costs resulting from our expanded geographic footprint and larger base of revenue equipment. Claims and insurance expense in 2025 was $15.1 million higher than 2024 largely due to the development on open cases and increased cost per claim. The Company experiences volatility in claims and insurance expenses from time to time as a result of utilizing self-insurance as a part of its risk management program. Depreciation and amortization expense increased $38.5 million in 2025 compared to 2024 primarily due to ongoing investments in revenue equipment, our terminal network and technology. Operating (gains) losses, net decreased $16.9 million in 2025 compared to 2024 due to a gain on the sale of a terminal of $16.4 million, partially offset by a real estate impairment loss of $1.9 million.

Other

Interest expense in 2025 was $7.5 million greater than 2024 due to increased average borrowings under the credit arrangements in 2025. Interest income in 2025 was $0.9 million less than 2024 due to decreased average deposit balances during the period. The effective income tax rate was 24.4 and 23.9 percent for the years ended December 31, 2025 and 2024, respectively.

Outlook

Our business remains closely correlated with non-service sectors of the general economy and competitive pricing pressures, as well as the success of Company-specific improvement initiatives. Our outlook is dependent on a number of external factors, including strength of the economy, inflation, changes in regulatory conditions and international trade relations, including tariff volatility, labor availability, diesel fuel prices and supply chain constraints. The potential impact of these factors on our operations, financial performance and financial condition, as well as the impact on our ability to successfully execute our business strategies and initiatives, remains uncertain and difficult to predict. We are continuing initiatives to improve and enhance customer service in an effort to support our ongoing pricing and business mix optimization, while seeking to control costs and improve productivity. Planned revenue initiatives include building density in our current geography, targeted marketing initiatives to grow revenue in more profitable areas and further expanding our geographic and terminal network. On October 1, 2025, Saia implemented a 5.9 percent general rate increase for customers comprising approximately 25 percent of Saia’s

operating revenue. The success of these revenue initiatives is impacted by what proves to be the underlying economic trends, competitor initiatives and other factors discussed under “Cautionary Note Regarding Forward-Looking Statements” and Part I, Item 1A., “Risk Factors.”

Effective October 2025, the Company implemented a salary and wage increase of approximately 3.0 percent for all of its employees, excluding executives. The total cost of the compensation increase is expected to be approximately $34.9 million annually, and the Company anticipates the impact will be partially offset by productivity and efficiency gains.

The strategic objective of the Company is to build market share through excellent customer service, continued operating efficiencies and through its geographic and terminal expansion which should result in numerous operating leverage cost benefits. However, should the economy soften, the Company plans to match resources and capacity to shifting volume levels to lessen unfavorable operating leverage. The success of cost improvement initiatives is impacted by a number of factors. These factors include the cost and availability of personnel and purchased transportation and the cost of diesel fuel, claims and insurance and other inflationary factors.

See “Cautionary Note Regarding Forward-Looking Statements” and Part I, Item 1A., “Risk Factors,” for a more complete discussion of potential risks and uncertainties that could materially adversely affect our financial condition, results of operation, cash flows and prospects.

Accounting Pronouncements Adopted in 2025

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” Under this ASU, income tax disclosures are expanded primarily by requiring the disaggregation of the rate reconciliation and income taxes paid disclosures. This standard is effective for annual reporting periods beginning after December 15, 2024. The Company adopted the standard on a retrospective basis for the 2025 annual reporting period with the impact limited to incremental disclosures in our consolidated financial statements.

Recently Issued Accounting Pronouncements

In November 2024, the FASB issued ASU No. 2024-03, "Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses." Under this ASU, entities are required to disclose additional disaggregated information related to certain expense captions included in the Consolidated Statements of Operations. This standard is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

In July 2025, the FASB issued ASU No. 2025-05, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets." Under this ASU, a practical expedient is provided that assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset for current accounts receivable and current contract assets. This standard is effective for annual reporting periods beginning after December 15, 2025, and for interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU No. 2025-06, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software." Under this ASU, all references to prescriptive and sequential software development stages are eliminated and capitalization of software costs is required to start when management has authorized and committed to funding the software project and it is probable that the project will be completed and the software will be used to perform the function intended. This standard is effective for annual reporting periods beginning after December 15, 2027 and for interim periods within those fiscal years. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

Financial Condition, Liquidity and Capital Resources

The Company's liquidity needs arise primarily from capital investment in new equipment, land and structures, information technology and letters of credit and surety bonds required under insurance programs, as well as funding working capital requirements.

Working Capital and Capital Expenditures

Working capital at December 31, 2025 was $169.2 million compared to $157.4 million at December 31, 2024. This increase is primarily due to an increase in accounts receivable of $9.2 million and a decrease in accounts payable of $7.1 million, partially offset by a decrease in income taxes receivable of $11.6 million.

A summary of our cash flows is presented below:


	Years ended
	2025	2024
	(in thousands)
Cash and cash equivalents, beginning of year	$19,473	$296,215
Net Cash flows provided by (used in):
Operating activities	594,973	583,702
Investing activities	(552,522)	(1,035,864)
Financing activities	(42,204)	175,420
Net Increase (Decrease) in Cash and Cash Equivalents	247	(276,742)
Cash and cash equivalents, end of year	$19,720	$19,473

Cash flows from operating activities were $595.0 million for 2025 versus $583.7 million for 2024 largely driven by changes in other assets and liabilities, and increased depreciation and amortization, partially offset by net gains from property disposals. For 2025, net cash used in investing activities was $552.5 million versus $1,035.9 million in 2024 primarily due to the acquisition of terminals from Yellow Corporation in January 2024 as well as decreased revenue equipment acquisitions in 2025 compared to 2024. Net cash used in financing activities was $42.2 million in 2025 versus $175.4 million provided by financing activities in 2024 as a result of higher borrowings to fund capital expenditures during 2024.

The Company has historically generated cash flows from operations to fund a large portion of its capital expenditure requirements. The Company believes it has adequate sources of capital to meet short-term liquidity needs through its cash on hand, operating cash flows and availability under its credit arrangements. As of December 31, 2025, the Company has $500.6 million of availability under its Revolving Credit Facility and $250 million of uncommitted financing under the Company's Private Shelf Agreement, subject to certain conditions. Future operating cash flows are primarily dependent upon the Company’s profitability and its ability to manage its working capital requirements, primarily accounts receivable, accounts payable as well as wage and benefit accruals. The Company was in compliance with its debt covenants at December 31, 2025.

Net capital expenditures pertain primarily to investments in tractors, trailers, other revenue equipment, information technology as well as land and structures. Projected net capital expenditures for 2026 are expected to be $350 million to $400 million compared to 2025 net capital expenditures of $544.1 million. Estimated 2026 capital expenditures include a normal replacement cycle of revenue equipment and technology investments for our operations, and additional revenue equipment and real estate investments to support our growth initiatives.

See “Cautionary Note Regarding Forward-Looking Statements” and Item 1A., “Risk Factors,” for a more complete discussion of potential risks and uncertainties that could materially affect our future performance and financial condition.

Net capital expenditures are summarized in the following table (in millions):


	Years ended
	2025	2024	2023
Land and structures:
Additions	$208.2	$504.0	$267.3
Sales	(19.5)	(0.2)	(0.1)
Revenue equipment, net	312.0	473.1	133.3
Technology and other	43.4	64.0	36.7

Total	$544.1	$1,040.9	$437.2

In addition to the amounts disclosed in the table above, the Company had an additional $10.5 million in capital expenditures for revenue equipment that was received but not paid for prior to December 31, 2025.

Credit Arrangements

Revolving Credit Facility

The Company is a party to an unsecured credit agreement with its banking group (the Revolving Credit Facility) that was amended in December 2024. 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 it 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 December 31, 2025.

At December 31, 2025, the Company had outstanding borrowings of $63.0 million and outstanding letters of credit of $36.4 million under the Revolving Credit Facility. At December 31, 2024, the Company had $94.0 million of outstanding borrowings and outstanding letters of credit of $32.2 million under the Revolving Credit Facility.

See Note 2, "Debt and Financing Arrangements" of the accompanying audited Consolidated Financial Statements for more information on 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.

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 December 31, 2025.

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

See Note 2, "Debt and Financing Arrangements" of the accompanying audited Consolidated Financial Statements for more information on the Shelf Agreement.

Finance Leases

The Company is obligated under finance leases with seven-year terms for revenue equipment totaling $1.0 million and $6.3 million as of December 31, 2025 and 2024, respectively. Amortization of assets held under the finance leases is included in depreciation and amortization expense. The weighted average interest rates for the finance leases at December 31, 2025 and 2024 were 3.53% and 4.09%, respectively.

Contractual Obligations

Contractual obligations for the Company are comprised of lease agreements, purchase obligations and long-term debt obligations related to any outstanding balance under the credit arrangements. Contractual obligations for operating leases at December 31, 2025 totaled $168.2 million. This includes operating leases with original maturities of less than one year, which are not recorded in our consolidated balance sheet in accordance with U.S. generally accepted accounting principles. Contractual obligations in the form of finance leases were $1.0 million at December 31, 2025, which include both principal and interest components. Purchase obligations at December 31, 2025 were $14.8 million. As of December 31, 2025 the Revolving Credit Facility had a $63.0 million outstanding principal balance and the Shelf Agreement had a $100.0 million outstanding principal balance. See Note 2, "Debt and Financing Arrangements" of the accompanying audited Consolidated Financial Statements for more information on the credit arrangements.

Other commercial commitments of the Company typically include letters of credit and surety bonds required for collateral under insurance agreements. As of December 31, 2025 the Company had total outstanding letters of credit of $36.4 million and $58.4 million in surety bonds.

In addition to any principal amounts disclosed, the Company has interest obligations of approximately $10.7 million for 2026, based on borrowings and commitments outstanding at December 31, 2025.

The Company has accrued approximately $3.0 million for uncertain tax positions and accrued interest and penalties of $0.4 million related to the uncertain tax positions as of December 31, 2025.

At December 31, 2025, the Company has $125.1 million accrued for claims, insurance and other liabilities.

Critical Accounting Policies and Estimates

The Company makes estimates and assumptions in preparing the consolidated financial statements that affect reported amounts and disclosures therein. In the opinion of management, the accounting policies that generally have the most significant impact on the financial position and results of operations of the Company include:

•

Claims and Insurance Accruals.

Description: The Company is self-insured for certain levels of workers’ compensation, bodily injury and property damage, casualty, cargo loss and damage and group health claims.

Judgments and Uncertainties: Claims and insurance accruals for these claims 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.

Sensitivity of Estimate to Change: These accruals could be significantly affected if the actual costs of these claims differ from the estimates and assumptions used to establish the accruals. A significant number of these claims typically take several years to develop and even longer to ultimately settle. These accruals have been reasonably accurate over time; however, changes to estimates and assumptions regarding severity of claims, medical cost inflation, as well as specific case facts can create short-term volatility in these accruals. A 100 basis point change in our loss development factors would result in an immaterial change in the claims and insurance accruals. There have been no material changes in the development factors for the year ended December 31, 2025.

•

Revenue Recognition and Related Allowances.

Description: Revenue is recognized over the transit time of the shipment as it moves from origin to destination while expenses are recognized as incurred. Estimates included in the recognition of revenue and accounts receivable include estimates related to shipments in transit and estimates of future adjustments to revenue and accounts receivable for billing adjustments and collectability.

Judgments and Uncertainties: Revenue is recognized in a systematic process whereby estimates related to shipments in transit are based upon actual bills of lading received near period end and the estimated percentage of completion of the service at period end. Estimates for credit losses and billing adjustments are based upon historical experience.

Sensitivity of Estimate to Change: Since the cycle for pick-up and delivery of shipments is generally one to five days, typically less than ten percent of a total month’s revenue is in transit at the end of any month. Estimates included in the recognition of revenue and accounts receivable are continuously evaluated and updated; however, changes in economic conditions, customer creditworthiness, pricing arrangements and other factors may significantly impact these estimates.

•

Depreciation of Assets.

Description: Under the Company’s accounting policy for property and equipment, management establishes depreciable lives and salvage values for the Company’s revenue equipment (tractors and trailers) based on their estimated useful lives and estimated residual values to be received when the equipment is sold or traded in. These estimates are routinely evaluated and updated when circumstances warrant.

Judgments and Uncertainties: Selecting the appropriate accounting method for depreciation requires management judgment, as there are multiple acceptable methods that are in accordance with U.S. generally accepted accounting principles, including straight-line, declining-balance, and sum-of-the-years' digits. The Company depreciates property and equipment on straight-line and declining-balance bases over the estimated useful lives of the assets. The Company believes these methods properly spread the costs over the useful lives of the assets. Factors affecting estimated useful lives and residual values of property and equipment may include estimating loss, damage, obsolescence, and Company policies around maintenance and asset replacement.

Sensitivity of Estimate to Change: Actual useful lives and residual values could differ from these assumptions based on market conditions and other factors, thereby impacting the estimated amount or timing of depreciation expense. See Note 1, "Description of Business and Summary of Accounting Policies" of the accompanying audited Consolidated Financial Statements, for discussion of the effects of changes to judgments related to depreciation expense for the year ended December 31, 2025.

These accounting policies and others are described in further detail in the Notes to the audited Consolidated Financial Statements included in this Form 10-K.

The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to adopt accounting policies and make significant judgments and estimates to develop amounts reflected and disclosed in the consolidated financial statements. In many cases, there are alternative policies or estimation techniques that could be used. We maintain a thorough process to review the application of our accounting policies and to evaluate the appropriateness of the many estimates that are required to prepare the consolidated financial statements. However, even under optimal circumstances, estimates routinely require adjustment based on changing circumstances and the receipt of new or better information.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

The Company is exposed to a variety of market risks including the effects of interest rates and diesel fuel prices. The detail of the Company’s debt structure is more fully described in the Notes to the audited Consolidated Financial Statements set forth in this Form 10-K. To help mitigate our exposure to rising diesel fuel prices, the Company has an established fuel surcharge program.

The following table provides information about the Company’s debt as of December 31, 2025. The table presents annual principal cash flows (in millions) and related weighted average interest rates by contractual maturity dates. 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.

To the Stockholders and Board of Directors
Saia, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Saia, Inc. and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 24, 2026 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Evaluation of the estimated liabilities for self-insured workers’ compensation and bodily injury claims

As discussed in Note 1 to the consolidated financial statements, the Company has recorded estimated liabilities for claims related to workers’ compensation and bodily injury. These liabilities are recorded within claims and insurance accruals (current) of $46.0 million, and claims, insurance, and other (non-current) of $79.1 million, as of December 31, 2025.

We identified the evaluation of the estimated liabilities for self-insured workers’ compensation and bodily

injury claims as a critical audit matter because of the inherent uncertainty in the amounts that will ultimately be paid to settle these claims. Factors that may affect the settlement cost of claims include the length of time the claim remains open, its potential severity, and the results of litigation. Additionally, the Company’s liabilities include estimates for future development of claims and specialized skills were needed to evaluate the actuarial methods and assumptions used to make these estimates.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s self-insurance processes, including controls over the methods and assumptions used in estimating the liabilities. We evaluated the Company’s accruals for a selection of reported claims by comparing the individual accruals to current available information, which included claim files and attorneys’ letters, and we tested the Company’s historical paid loss data by inspecting a sample of claim payments. In addition, we involved an actuarial professional with specialized skills and knowledge, who assisted by comparing the Company’s actuarial methods with generally accepted actuarial methods and evaluating the key assumptions used in determining the liabilities.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors
Saia, Inc.:

Opinion on Internal Control Over Financial Reporting

We have audited Saia, Inc. and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements), and our report dated February 24, 2026 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

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.

Notes to Consolidated Financial Statements

December 31, 2025, 2024 and 2023

1. Description of Business and Summary of Accounting Policies

Description of Business

Saia, Inc., and its subsidiaries (Saia or the Company), is headquartered in Johns Creek, Georgia. Saia is a leading, less-than-truckload (LTL) motor carrier with approximately 97% of its revenue derived from transporting LTL shipments for customers. In addition to the core LTL services provided in the United States, the Company also offers customers a wide range of other value-added services, including brokered truckload and expedited transportation and other logistics services across North America.

Basis of Presentation

The accompanying consolidated financial statements include the accounts of Saia, Inc. and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements.

Use of Estimates

The preparation of our consolidated financial statements in conformity with U.S. generally accepted accounting principles requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenues and expenses. Management makes its best estimate of the ultimate outcome for these items based on historical trends and other information available when the financial statements are prepared. Changes in estimates are recognized in accordance with the accounting rules for the estimate, which is typically in the period when new information becomes available to management. Areas where the nature of the estimate makes it reasonably possible that actual results could materially differ from amounts estimated include: revenue reserves; self-insurance accruals; long-term incentive compensation; tax liabilities; loss contingencies; litigation claims; and impairment assessments on long-lived assets and goodwill.

Accounting Pronouncements Adopted in 2025

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” Under this ASU, income tax disclosures are expanded primarily by requiring the disaggregation of the rate reconciliation and income taxes paid disclosures. This standard became effective for annual reporting periods beginning after December 15, 2024. The Company adopted the standard on a retrospective basis for the 2025 annual reporting period with the impact limited to incremental disclosures in our consolidated financial statements.

Recently Issued Accounting Pronouncements

In July 2025, the FASB issued ASU No. 2025-05, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets." Under this ASU, a practical expedient is provided that assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset for current accounts receivable and current contract assets. This standard is effective for annual reporting periods beginning after December 15, 2025, and for interim periods within those fiscal years. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

Summary of Accounting Policies

Significant accounting policies and practices used in the preparation of the accompanying consolidated financial statements are as follows:

Cash and Cash Equivalents: Cash and cash equivalents includes cash on hand and short term marketable securities with original maturities of three months or less.

Spare Parts, Fuel and Operating Supplies: Spare parts, fuel and operating supplies on hand are carried at average cost and are included in other current assets on the accompanying consolidated balance sheets.

Property and Equipment: Property and equipment are carried at cost less accumulated depreciation. Replacements and improvements that extend the useful life of an asset are capitalized, while repairs and maintenance that do not improve or extend the lives of the respective assets are charged to expense as incurred. The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate the carrying value of assets may not be recoverable.

Depreciation is computed using the straight-line method, except for tractors (included in revenue equipment) for which the declining-balance method is used. The following service lives are used to compute depreciation:


				Years
Structures				15 to 25
Revenue equipment				6 to 20
Technology equipment and software				3 to 5
Other				3 to 10

At December 31, property and equipment consisted of the following (in thousands):


	2025		2024
Land	$	360,369	$	350,593
Structures		1,399,227		1,238,969
Revenue equipment		2,055,037		1,810,389
Technology equipment and software		253,997		225,504
Other		190,808		164,614

Total property and equipment, at cost	$	4,259,438	$	3,790,069

The Company’s investment in technology equipment and software consists primarily of systems to support customer service, maintenance and freight management. Depreciation and amortization expense (including amortization of assets under finance leases) was $247.7 million, $209.2 million and $177.9 million for the years ended December 31, 2025, 2024 and 2023, respectively.

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 was recognized prospectively. The changes in estimates resulted in an increase in income from continuing operations of

approximately $2.9 million and $7.7 million (a $2.2 million and $5.8 million increase in net income) for the years ended December 31, 2025 and 2024, respectively.

Claims and Insurance Accruals: The Company maintains a significant amount of 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.

Income Taxes: Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period enacted. As required by FASB Accounting Standards Codification (ASC) Topic 740, Income Taxes, the Company defines the threshold for recognizing the benefits of tax-filing positions in the financial statements as “more-likely-than-not” to be sustained by the tax authority.

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 from one to five 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, brokered 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 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.

Credit Risk: The Company routinely grants credit to its customers. The risk of significant loss in trade receivables is substantially mitigated by the Company’s credit evaluation process, short collection terms, low revenue per transaction and services performed for a large number of customers, with no single customer representing more than 5 percent of accounts receivable at year-end. Allowances for potential credit losses are based on historical loss experience, current economic environment, expected trends and customer specific factors.

Stock-Based Compensation: The Company has various stock-based compensation plans for its employees and non-employee directors. The Company stock-based compensation includes awards of stock options, restricted stock awards, and stock-based performance unit awards, all of which are accounted for under FASB ASC Topic 718,

Compensation-Stock Compensation. Stock options granted to employees are valued using a Black-Scholes-Merton model with the expense amortized over the three-year vesting period. Restricted stock is valued based on the fair market value of the Company's common stock at the date of grant and the expense is amortized over the three to five year vesting period. Stock-based performance unit awards are valued using a Monte Carlo model and the expense is amortized over the three-year performance period.

Intangible Assets: The Company tests goodwill for impairment annually and whenever events or changes in circumstance indicate that impairment may have occurred. The Company first performs a qualitative assessment to determine whether it is necessary to perform a quantitative assessment. The Company is not required to estimate the fair value of a reporting unit unless the Company determines, based on qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. Purchased intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Other Current Liabilities: Other current liabilities are mainly comprised of other accrued taxes. Other accrued taxes were $26.0 million and $31.7 million for the years ended December 31, 2025 and 2024, respectively.

Advertising: The costs of advertising are expensed as incurred. Advertising costs charged to expense were $2.7 million, $5.0 million, and $2.9 million for the years ended December 31, 2025, 2024 and 2023, respectively.

Financial Instruments: The carrying amounts of financial instruments including cash and cash equivalents, accounts receivable and accounts payable approximated fair value as of December 31, 2025 and 2024, because of the relatively short maturity of these instruments. See Note 2 for fair value disclosures related to debt.

Segment Reporting: Saia is comprised of a single reportable segment organized around its transportation services. The segment provides core LTL and a wide range of other value-add transportation services to its customers based on negotiated prices contained in either a transportation services agreement or a publicly disclosed tariff rate. Saia derives revenue primarily in the United States and manages its business activities on a consolidated basis using an integrated transportation network.

The chief operating decision maker (CODM) is the Chief Executive Officer who regularly reviews the operating results of the Company's single operating segment at the consolidated company level. The accounting policies of the segment are the same as those described in the summary of significant accounting policies. The CODM assesses performance for the segment and determines how to allocate resources based on Saia's consolidated net income.

The CODM uses net income to evaluate income generated from segment assets (return on assets) in deciding whether to reinvest profits into the Company or for other purposes, such as for acquisitions, to repay borrowings or to pay dividends. The CODM also uses net income to monitor budget versus actual results, and in competitive analysis by benchmarking to the Company’s competitors. The competitive analysis along with the monitoring of budgeted versus actual results are used in assessing performance of the Company and in establishing management’s compensation.

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):

The Company is party to a credit agreement with a group of banks as well as a private shelf debt agreement to fund capital investments, letters of credit and working capital needs. The payment of dividends is restricted under the Company's credit arrangements.

Credit Arrangements

Revolving Credit Facility

The Company is a party to an unsecured credit agreement with its banking group (the Revolving Credit Facility) that was amended in December, 2024. 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 it 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 December 31, 2025

The carrying amount of the Company’s variable rate debt approximates fair value as interest rates approximate the current rates available to the Company.

Private Shelf Agreement

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.

At December 31, 2025 and 2024, the Company had outstanding notes under the Shelf Agreement of $100.0 million. The estimated fair value of these notes approximates book value for each year.

Finance Leases

The Company is obligated under finance leases with seven-year terms which include obligations collateralized by revenue equipment totaling $1.0 million and $6.3 million as of December 31, 2025 and 2024, respectively. Amortization of assets held under the finance leases is included in depreciation and amortization expense.

The estimated fair value of the finance leases at December 31, 2025 and 2024 is $1.0 million and $6.3 million, respectively, which is based on current market interest rates for similar types of financial instruments, reflective of Level 2 inputs.

7. Stockholders’ Equity

Deferred Compensation Plan

The Saia Executive Capital Accumulation Plan (Capital Accumulation Plan) is a nonqualified deferred compensation plan for Saia executives. The Capital Accumulation Plan allows for the plan participants to invest in the Company’s common stock. Elections to invest in the Company’s common stock are irrevocable, and upon distribution, the funds invested in the Company’s common stock are paid out in Company common stock rather than

cash. At December 31, 2025 and 2024, the Company’s rabbi trust, which holds the investments for the Capital Accumulation Plan, held 70,053 and 70,100 shares of the Company’s common stock, respectively, all of which were purchased on the open market.

The following table summarizes the shares of the Company’s common stock that were purchased and sold by the Company’s rabbi trust (in thousands except share amounts):

Company common stock held by the rabbi trust is accounted for within stockholders' equity similar to treasury stock at historical cost with the corresponding deferred compensation obligation also presented within stockholders' equity as additional paid-in capital.

Directors’ Deferred Compensation

Under the Company’s Directors’ Deferred Fee Plan, non-employee directors may elect to defer all or a portion of their annual fees and retainers. Such deferrals are converted into units equivalent to the value of the Company’s stock. Upon the director’s termination, death or disability, accumulated deferrals are distributed in the form of Company common stock in accordance with elections made by the directors. The Company had 104,399 and 101,951 shares reserved for issuance under the Directors’ Deferred Fee Plan at December 31, 2025 and 2024, respectively. The shares reserved for issuance under the Directors’ Deferred Fee Plan are treated as common stock in computing basic earnings per share.

8. Stock-Based Compensation

The stockholders of the Company approved the 2018 Omnibus Incentive Plan (the 2018 Omnibus Plan) and the Second Amended and Restated 2011 Omnibus Incentive Plan (the 2011 Omnibus Plan) to allow the Company to issue equity based compensation to help attract and retain executive, managerial, supervisory or professional employees and non-employee directors. The 2018 Omnibus Plan has 1,100,000 shares of common stock reserved. The 2011 Omnibus Plan had a total of 2,350,000 shares of common stock reserved. Following stockholder approval of the 2018 Omnibus Plan, no additional awards have been made under the 2011 Omnibus Plan.

The 2018 Omnibus Plan and the 2011 Omnibus Plan provide for the grant or award of stock options; stock appreciation rights; restricted and unrestricted stock; restricted stock units; and performance unit awards.

At December 31, 2025 and 2024, 391,089 shares remain reserved and unissued under the provisions of the 2011 Omnibus Plan, a portion of which are allocated to outstanding stock options described below.

The Company has historically issued new shares to satisfy stock option exercises or other awards issued under the 2018 Omnibus Plan and 2011 Omnibus Plan.

Stock option awards have been granted with an exercise price equal to the market price of the Company’s stock at the date of grant. Stock option awards granted to employees under the plans to date are non-qualified stock options, have vesting over three years, subject to earlier vesting upon a change of control and certain other events, and have a seven-year contractual term.

The Company grants shares of restricted stock as part of its long-term incentive plan. These shares of restricted stock generally vest over three years, subject to earlier vesting upon a change of control and certain other events. The value of restricted stock is based on the fair market value of the Company’s common stock at the date of grant. In

addition, the Company has periodically granted shares of restricted stock to certain key executives that vests 25% after three years, 25% after four years and the remaining 50% after five years, assuming the executive has been in continuous service to the Company since the award date, subject to earlier vesting upon a change of control and certain other events.

The criteria for payout of the awards is based on a comparison over the three-year performance period of these awards of the total stockholder return (TSR) of the Company’s common stock compared to the TSR of the companies in a peer group established by the Compensation and Human Capital Committee. These stock-based awards are accounted for in accordance with ASC Topic 718 with the expense amortized over the three-year performance period based on the fair value of the awards at the grant date measured using the Monte Carlo method. Operating results include expense for the performance unit awards of $6.0 million in 2025, $5.3 million in 2024 and $4.5 million in 2023. Shares earned under the performance unit awards are issued in the first quarter of the year following the end of the performance period.

Item 9A. Controls and Procedures

Annual Controls Evaluation and Related CEO and CFO Certifications

As of the end of the period covered by this Annual Report on Form 10-K, the Company conducted an evaluation of the effectiveness of the design and operation of its “disclosure controls and procedures” (Disclosure Controls). The Disclosure Controls evaluation was performed under the supervision and with the participation of management, including the Company’s Chief Executive Officer (CEO) and Chief Financial Officer (CFO).

Based upon the controls evaluation, the Company’s CEO and CFO have concluded that, as of the end of the period covered by this Annual Report on Form 10-K, the Company’s Disclosure Controls are effective to ensure that information the Company is required to disclose in reports that the Company files or submits under the Securities Exchange Act of 1934, as amended (the Exchange Act), is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms.

During the fourth quarter of 2025 covered by this Form 10-K, there were no changes in internal control over financial reporting that materially affected, or that are reasonably likely to materially affect, the Company’s internal control over financial reporting. Attached as Exhibits 31.1 and 31.2 to this Annual Report are certifications of the CEO and the CFO, which are required in accordance with Rule 13a-14 of the Exchange Act. This Controls and Procedures section includes the information concerning the controls evaluation referred to in the certifications and it should be read in conjunction with the certifications.

Definition of Disclosure Controls

Disclosure Controls are controls and procedures designed to ensure that information required to be disclosed in the Company’s reports filed under the Exchange Act is recorded, processed, summarized and reported timely. Disclosure Controls are also designed to ensure that such information is accumulated and communicated to the Company’s management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure. The Company’s Disclosure Controls include components of its internal control over financial reporting which consists of control processes designed to provide reasonable assurance regarding the reliability of the Company’s financial reporting and the preparation of financial statements in accordance with U.S. generally accepted accounting principles.

Limitations on the Effectiveness of Controls

The Company’s management, including the CEO and CFO, does not expect that its Disclosure Controls or its internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Management’s Report on Internal Control Over Financial Reporting

The management of Saia, Inc. and its subsidiaries is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) of the Securities Exchange Act of 1934.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 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.

The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025. In making this assessment, the Company’s management used the criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s assessment included a review of the documentation of controls, evaluation of the design effectiveness of controls and testing of the effectiveness of controls. Based on this assessment, management has concluded that as of December 31, 2025, the Company’s internal control over financial reporting is effective based on those criteria.

The Company’s independent registered public accounting firm, KPMG LLP, has issued an audit report on the Company’s internal control over financial reporting as of December 31, 2025, which report appears on page 49 of this Form 10-K.

Saia generated 2025 revenue of $3.2 billion, unchanged from 2024, but operating income declined to $352.2 million from $482.2 million. This indicates margin pressure and higher costs despite stable top-line performance across its nationwide less-than-truckload network.

What is Saia, Inc.’s core business and operating footprint?

Saia operates a national less-than-truckload (LTL) network, providing freight services across the 48 contiguous states with partners into Canada and Mexico. As of December 31, 2025, it ran 213 terminals, around 7,700 tractors and 26,500 trailers, plus additional offices and a warehouse.

How much has Saia invested in growth and modernization recently?

Over the past five years, Saia has invested in excess of $2.5 billion in capital expenditures. Spending focused on real estate, revenue equipment and technology to expand its terminal footprint, modernize the fleet for efficiency and safety, and enhance data analytics, customer service and network optimization.

What are the key risks Saia, Inc. highlights in its 10-K?

Saia cites exposure to economic cycles, intense competition, driver and labor shortages, diesel fuel volatility, inflation, and extensive transportation regulation. It also emphasizes risks from environmental rules, cybersecurity threats, seasonality, customer credit quality, high capital needs, and potential unionization of its currently union-free workforce.

How large is Saia’s workforce and what is its labor model?

Saia reports nearly 14,500 union-free employees, with about 51% commercial drivers and 24% dock workers. It focuses on direct employee relationships, competitive pay, health and wellness benefits, training, safety programs and a dock-to-driver pathway to support retention and operational flexibility without collective bargaining agreements.

What sustainability and environmental initiatives is Saia pursuing?

Saia is upgrading tractors and trailers to improve fuel efficiency, safety and emissions, and optimizing routes to cut fuel use. It operates over 55 CNG vehicles, uses renewable fuels where possible, runs recycling and energy-saving programs at terminals, and participates in the EPA’s SmartWay carrier performance and benchmarking program.

What capital spending does Saia plan for 2026?

Saia anticipates net capital expenditures of about $350 million to $400 million in 2026. Planned investments target new and existing terminals, additional tractors and trailers, and advanced technologies to support network growth, operational efficiency, safety and the company’s long-term less-than-truckload expansion strategy.
