RUSH ENTERPRISES INC \TX\

Previous wording

We have entered into nonexclusive dealership agreements with Peterbilt that authorize us to act as a dealer of Peterbilt trucks. Peterbilt may terminate our dealership agreements in the event of a change of control of the Company or if we violate any number of provisions in the dealership agreements. Under our Peterbilt dealership agreements, the following constitute a change of control: (i) with respect to the election of directors, the aggregate voting power held by W.M. “Rusty” Rush, Steven Keller, Corey Lowe, Jody Pollard, Jason Wilder, Michael Goldstone, Mike Eppes and Michael McRoberts, along with certain other persons who no longer work for the Company (collectively, the “Dealer Principals”) decreases below 22% (the Dealer Principals, excluding those who no longer work for the Company, controlled approximately 41.2% of the aggregate voting power with respect to the election of directors as of December 31, 2024); or (ii) any person or entity other than the Dealer Principals and their respective associates, or any person or entity who has been approved in writing by PACCAR, owns common stock with a greater percentage of the voting power with respect to the election of our directors than the Dealer Principals and their respective associates, in the aggregate, or any person other than Mr. Rush or any person who has been approved in writing by PACCAR, holds the office of Chairman of the Board and the President or Chief Executive Officer of the Company. We have no control over the transfer or disposition of Mr. Rush’s, or his estate’s, common stock. If Mr. Rush were to sell his Class B common stock or bequest his Class B common stock to a person or entity other than the Dealer Principals, or if his estate is required to liquidate its Class B common stock that it owns, directly or indirectly, to pay estate taxes or otherwise, the change of control provisions of the Peterbilt dealership agreements may be triggered, which would give Peterbilt the right to terminate our dealership agreements. If our dealership agreements with Peterbilt are terminated, we will lose the right to purchase Peterbilt products and operate as an authorized Peterbilt dealer, which would have a material adverse effect on our operations, revenues and profitability.

The commercial vehicle industry is predicted to experience change over the long-term. We see these changes beginning to occur, as certain of the manufacturers we represent now have vehicles with electric drivetrains available for purchase. Technological advances, including with respect to drivetrain electrification or other alternative fuel technologies, could potentially have a material adverse effect on our parts and service business, as such vehicles are currently being described as potentially requiring less service and having fewer parts. The effect of these technological advances on our business is still uncertain, as there are many factors that are unknowable at this time, including when the infrastructure to support widespread adoption of such vehicles will be in place and when such vehicles may be commercially available at price points that would lead to their widespread adoption. Regardless of where the industry goes with respect to alternative fuel vehicles, we believe that, due to the geographic reach of our dealership network, relationships with both the manufacturers we represent and our customers and our access to capital, we are well-positioned to serve our customers’ evolving needs.

Previous wording

The concerns over climate change may impact our business in the future. Our current business model depends on our ability to sell, and provide services to, commercial vehicles primarily powered by diesel and gasoline internal combustion engines, which produce nitrogen oxide and greenhouse gas emissions. While the manufacturers we represent have made substantial progress in reducing the amount of nitrogen oxide and greenhouse gas emissions that result from internal combustion engines, it is widely accepted that alternative fuel vehicles are necessary to address climate change. Reductions in the sale and use of commercial vehicles powered by internal combustion engines creates risks to our historical business operations and we cannot predict the future costs to our business resulting from these developments. However, we also believe that an industry transition away from internal combustion engines presents significant opportunities for us. Due in large part to the geographic reach of our dealership network, relationships with both the manufacturers we represent and our customers and our access to capital, we believe we are well-positioned to serve our customers’ evolving needs and help them reduce their nitrogen oxide and greenhouse gas emissions by helping them integrate more alternative fuel vehicles into their fleets and providing various services related thereto.

While the manufacturers we represent have made substantial progress in reducing the amount of nitrogen oxide and greenhouse gas emissions that result from internal combustion engines, it is widely accepted that alternative fuel vehicles will constitute an increasing portion of the commercial vehicles that are sold in the future as technology improves and costs decrease, or in the event that government regulations require manufacturers to produce alternative fuel vehicles.

Previous wording

As of December 31, 2024, our backlog of new commercial vehicle orders was approximately $1,512.7 million. Our backlog is determined quarterly by multiplying the number of new commercial vehicles for each particular type of commercial vehicle ordered by a customer at our Rush Truck Centers by the recent average selling price for that type of commercial vehicle. We only include confirmed orders in our backlog. However, such orders are subject to cancellation. In the event of order cancellation, we have no contractual right to the total revenues reflected in our backlog.

Current wording

As of December 31, 2025, our backlog of new commercial vehicle orders was approximately $1,109.6 million. Our backlog is determined quarterly by multiplying the number of new commercial vehicles for each particular type of commercial vehicle ordered by a customer at our Rush Truck Centers by the recent average selling price for that type of commercial vehicle. We only include confirmed orders in our backlog. However, such orders are subject to cancellation. In the event of order cancellation, we have no contractual right to the total revenues reflected in our backlog.

Previous wording

Given the current uncertainty in connection with recently proposed tariffs against Canada, Mexico and China, we believe that certain commercial vehicle orders currently reflected in our backlog could be cancelled in the event that such tariffs are enacted and significantly increase the aggregate price that our customers will have to pay for such vehicles.

Current wording

Given the current uncertainty in connection with recently enacted 25% tariff on certain medium– and heavy– duty commercial vehicles and parts (the “Commercial Vehicle Tariffs”), we believe that certain commercial vehicle orders currently reflected in our backlog could be cancelled in the event that such tariffs significantly increase the aggregate price that our customers will have to pay for such vehicles. However, we are confident that any price increases will be well below the 25% tariff rate and at this time, we do not expect the Commercial Vehicle Tariffs to significantly impact our backlog.

Previous wording

We are subject to risks associated with commercial vehicles and parts manufactured outside of the United States.

Current wording

We are subject to risks associated with commercial vehicles and parts manufactured outside of the United States, and the Commercial Vehicle Tariffs may impact demand for certain of the commercial vehicles and parts that we sell.

Previous wording

A group of seventeen U.S. states and the District of Columbia entered into a joint memorandum of understanding that adopts at least a portion of CARB’s emissions regulations and commits each of them to work together to advance and accelerate the market for electric Class 3 through 8 commercial vehicles. Six of the states that signed are states where we sell new commercial vehicles: California, Colorado, New Mexico, North Carolina and Virginia. The signatories to the memorandum all agreed on a goal of ensuring that 100% of new Class 3 through 8 commercial vehicles are zero emission by 2050, with an interim target of 30% zero emission vehicles by 2030, although multiple of these states have recently announced plans to delay various aspects of CARB’s regulations. Attaining these goals would likely require the adoption of new laws and regulations and we cannot predict at this time whether such laws and regulations would have an adverse impact on our business.

Six of the states are states where we operate commercial vehicle dealerships: California, Colorado, Nevada, New Mexico, North Carolina and Virginia. The signatories to the memorandum all agreed on a goal of ensuring that 100% of new Class 3 through 8 commercial vehicles are zero emission by 2050, with an interim target of 30% zero emission vehicles by 2030, although multiple of these states have recently announced plans to delay various aspects of CARB’s regulations. If CARB were to prevail in its legal challenges against Congress’ recission of the EPA waivers, attaining the goals stated by CARB and the signers of the joint memorandum would likely require the adoption of new laws and regulations and we cannot predict at this time whether such laws and regulations would have an adverse impact on our business. Similarly, if the EPA’s policies change in the future, we believe the EPA could issue a new endangerment finding with respect to GHG emissions, which would allow the EPA to potentially create a new rule similar to the recently voided GHG rules, which would have required commercial vehicle engine manufacturers to manufacture an increasing percentage of “zero-emission” vehicles over time, which would likely have reduced the number of diesel ICE vehicles that would have been manufactured over that time period.

Previous wording

Engine emissions rules and regulations could affect demand for the products that we sell in certain markets. For example, we believe that the HD Omnibus and Advanced Clean Truck rules, and the uncertainty regarding CARB’s enforcement of the same, resulted in our California dealerships selling less new commercial vehicles in 2024 than they would have absent such rules. While the reduction in the number of new commercial vehicles that we were able to sell in 2024 due to CARB’s rules was not material to our financial results, our success going forward depends on the ability of our manufacturers to successfully supply new commercial vehicles that comply with existing and future emissions rules and regulations in each of the markets in which we operate.

Current wording

Engine emissions rules and regulations could result in increased compliance costs, additional operating restrictions and affect demand for the products that we sell and services that we offer. For example, we believe that certain of CARB’s engine emissions rules that became effective in January 2024, along with the uncertainty regarding CARB’s enforcement of the same, resulted in our California dealerships selling less new commercial vehicles in both 2024 and 2025 than they would have absent such rules. While the reduction in the number of new commercial vehicles that we were able to sell in 2024 and 2025 due to CARB’s rules was not material to our financial results, our success going forward depends on the ability of our manufacturers to successfully supply new commercial vehicles that comply with existing and future emissions rules and regulations in each of the markets in which we operate.

We have, from time to time, experienced threats to our data and systems, including malware, ransomware, phishing and computer virus attacks. As discussed above, we are continuously developing and enhancing our controls, processes, and practices designed to protect our systems, computers, software, data, and networks from attack, damage, or unauthorized access. This continued development and enhancement requires us to expend significant additional resources. However, we may not anticipate or combat all types of future attacks until after they have been launched. If any of these breaches of security occur, we will be required to expend additional capital and other resources, including costs to deploy additional personnel and protection technologies, train employees and engage third-party experts and consultants.

Previous wording

We utilize a captive insurance company to provide our auto and general commercial liability insurance, which we supplement with excess insurance coverage. We self-insure the real property that we own and our personal property (excluding our vehicle inventory, which is insured). We also maintain various insurance policies with third-party insurers, each of which are subject to deductibles with high dollar amounts. We may be exposed to claims for which coverage is not afforded or the damages exceed the limits of our insurance coverage or multiple claims causing us to incur significant out-of-pocket costs before reaching the deductible amount, all of which could adversely affect our financial condition and results of operations. In addition, the cost of third-party insurance policies may increase significantly upon renewal of those policies as a result of general rate increases for the type of insurance we carry as well as our historical experience and experience in our industry. Although we have not experienced any material losses that were not covered by insurance, our existing or future claims may exceed the coverage level of our insurance, and such insurance may not continue to be available on economically reasonable terms, or at all. If we are required to pay significantly higher premiums for insurance, are not able to maintain insurance coverage at affordable rates or if we must pay amounts in excess of claims covered by our insurance, we could experience higher costs that could adversely affect our financial condition and results of operations. In fact, due to the rising costs of premiums over the last couple of years, we have been generally increasing our use of self-insurance programs and increasing the amounts of our deductibles.

Collectively, Mr. Rush and his affiliate own approximately 0.3% of our issued and outstanding shares of Class A common stock and 44.3% of our issued and outstanding Class B common stock. Mr. Rush collectively controls approximately 35.6% of the aggregate voting power of our outstanding shares, which is substantially more than any other person or group. The interests of Mr. Rush may not be consistent with the interests of all shareholders. As a result of such ownership, Mr. Rush has the ability to exercise substantial control over the Company, including with respect to the election of directors, the determination of matters requiring shareholder approval and other matters pertaining to corporate governance.

The volume of trading in our Class B common stock varies greatly and may often be light. As of December 31, 2024, the three-month average daily trading volume of our Class B common stock was approximately 17,000 shares, with twenty-three days having a trading volume below 10,000 shares. If any large shareholder were to begin selling shares in the market, the added available supply of shares could cause the market price of our Class B common stock to drop. In addition, the lack of a robust resale market may require a shareholder to sell a large number of shares of our Class B common stock in increments over time to mitigate any adverse impact of the sales on the market price of our Class B common stock.

Current wording

The volume of trading in our Class B common stock varies greatly and may often be light. As of December 31, 2025, the three-month average daily trading volume of our Class B common stock was approximately 36,000 shares, with eleven days having a trading volume below 10,000 shares. If any large shareholder were to begin selling shares in the market, the added available supply of shares could cause the market price of our Class B common stock to drop. In addition, the lack of a robust resale market may require a shareholder to sell a large number of shares of our Class B common stock in increments over time to mitigate any adverse impact of the sales on the market price of our Class B common stock.
