NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1–** Principles of Consolidation and Basis of Presentation**

The interim consolidated financial statements included herein have been prepared by Rush Enterprises, Inc. and its subsidiaries (collectively referred to as the “Company”), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). All adjustments have been made to the accompanying interim consolidated financial statements, which, in the opinion of the Company’s management, are necessary for a fair presentation of its operating results. All adjustments are of a normal recurring nature. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. It is recommended that these interim consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. Results of operations for interim periods are not necessarily indicative of results that may be expected for any other interim periods or the full fiscal year.

Restricted Cash

Restricted cash consists of deposits for the statutory restriction on cash related to the Company’s captive insurance company of $6.7 million as of March 31, 2026.

Foreign Currency Transactions

The functional currency of the Company’s foreign subsidiary, Rush Truck Centres of Canada Limited (“RTC Canada”), is the local currency, the Canadian dollar. Results of operations for RTC Canada are translated to USD using the average exchange rate on a monthly basis during each quarter. The assets and liabilities of RTC Canada are translated into USD using the exchange rate in effect on the balance sheet date. The related translation adjustments are recorded as a separate component of the Company’s Consolidated Statements of Shareholders’ Equity in accumulated other comprehensive income (loss).

2–** Commitments and Contingencies**

From time to time, the Company is involved in litigation arising out of its operations in the ordinary course of business. The Company maintains liability insurance through self-insurance, a captive insurer and third-party excess insurance, including product liability coverage, in amounts deemed adequate by management. However, an uninsured or partially insured claim, or claim for which indemnification is not available, could have a material adverse effect on the Company’s financial condition or results of operations. As of March 31, 2026, the Company believes that there are no pending claims or litigation, individually or in the aggregate, that are reasonably possible to have a material adverse effect on its financial position or results of operations. However, due to the inherent uncertainty of litigation, there can be no assurance that the resolution of any particular claim or proceeding would not have a material adverse effect on the Company’s financial condition or results of operations for the fiscal period in which such resolution occurred.

3–** Earnings Per Share**

The following table sets forth the computation of basic and diluted earnings per share (in thousands, except per share information):

Options to purchase shares of common stock that were outstanding for the three months ended March 31, 2026 and 2025 that were not included in the computation of diluted earnings per share because the effect would have been anti-dilutive are as follows (in thousands):

4–** Stock Options and Restricted Stock Awards**

Valuation and Expense Information

The Company accounts for stock-based compensation in accordance with Accounting Standards Codification (“ASC”) 718-10,Compensation–* Stock Compensation,* which requires the measurement and recognition of compensation expense for all share-based payment awards made to the Company’s employees and directors, including employee stock options, restricted stock awards and employee stock purchases related to the Employee Stock Purchase Plan, based on estimated fair values.

Stock-based compensation expense, calculated using the Black-Scholes option-pricing model for employee stock options, and included in selling, general and administrative expense, was $14.5 million for the three months ended March 31, 2026, and $13.7 million for the three months ended March 31, 2025.

As of March 31, 2026, the Company had $20.9 million of unrecognized compensation expense related to non-vested employee stock options to be recognized over a weighted-average period of 2.5 years and $25.2 million of unrecognized compensation cost related to non-vested restricted stock awards to be recognized over a weighted-average period of 1.6 years.

5–** Financial Instruments and Fair Value**

The Company measures certain financial assets and liabilities at fair value on a recurring basis. Financial instruments consist primarily of cash, accounts receivable, accounts payable and floor plan notes payable. The carrying values of the Company’s financial instruments approximate fair value due either to their short-term nature or existence of variable interest rates, which approximate market rates. Certain methods and assumptions were used by the Company in estimating the fair value of financial instruments as of March 31, 2026, and December 31, 2025. The carrying value of current assets and current liabilities approximates the fair value due to the short maturity of these items.

The fair value of the Company’s long-term debt is based on secondary market indicators. Because the Company’s debt is not quoted, estimates are based on each obligation’s characteristics, including remaining maturities, variable interest rate, credit rating, collateral and liquidity. Accordingly, the Company concluded that the valuation measurement inputs of its long-term debt represent, at its lowest level, current market interest rates available to the Company for similar debt and the Company’s current credit standing. Thus, the carrying amount of such debt approximates fair value.

6–** Segment Information**

The Company reports information based on operating segments identified in accordance with how the chief operating decision maker (“CODM”) evaluates business performance and allocates resources. As of the reporting period, the Company operates with one CODM: W.M. “Rusty” Rush, the Chief Executive Officer, President and Chairman of the Board.

As of the reporting period, the Company currently hasone reportable business segment - the Truck Segment. The Truck Segment includes the Company’s operation of a network of commercial vehicle dealerships in the United States and Ontario, Canada that provide an integrated one-stop source for the commercial vehicle needs of its customers, including retail sales of new and used commercial vehicles; aftermarket parts sales, service and collision center facilities; vehicle upfitting and financial services, including the financing of new and used commercial vehicle purchases, insurance products and truck leasing and rentals. The commercial vehicle dealerships are deemed a single reporting unit because they have similar economic characteristics. The Company’s CODM considers the entire Truck Segment, not individual dealerships or departments within its dealerships, when making decisions about resources to be allocated to the segment and assessing its performance.

In addition to the Truck Segment, the Company generates revenue from two additional operating segments: Retail Tire Sales and Insurance Services. These operating segments do not meet the quantitative thresholds for separate reporting as specified under the guidance of Accounting Standards Update (“ASU”) 2023-07. Therefore, they are consolidated under the “All Other” category in the segment disclosures below. These segments share accounting policies consistent with the summary of significant accounting policies.

The accounting policies of the segments are the same as those described in the summary of significant accounting policies. The Company evaluates performance based on segment operating income, not including extraordinary items.

The following table contains summarized information about reportable segment revenues, segment income or loss from continuing operations and segment assets for the periods ended March 31, 2026 and 2025 (in thousands):

7–** Income Taxes**

The Company had unrecognized income tax benefits totaling $7.9 million as a component of accrued liabilities as of March 31, 2026 and December 31, 2025, the total of which, if recognized, would impact the Company’s effective tax rate. An unfavorable settlement would require a charge to income tax expense and a favorable resolution would be recognized as a reduction to income tax expense. The Company recognizes interest accrued related to unrecognized tax benefits in income tax expense. The Company had approximately $625,000 accrued for the payment of interest as of March 31, 2026 and December 31, 2025. No amounts were accrued for penalties.

8–** Revenue**

The Company’s revenues are generated from the sale of finished products to customers. Those sales predominantly contain a single delivery element and revenue from such sales is recognized when the customer obtains control, which is typically when the finished product is delivered to the customer. The Company’s material revenue streams have been identified as the following: the sale of new and used commercial vehicles, the arrangement of associated commercial vehicle financing and insurance contracts, the performance of commercial vehicle repair services and the sale of commercial vehicle parts. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues.

The following table summarizes the Company’s disaggregated revenue by revenue source, excluding lease and rental revenue, for the three months ended March 31, 2026 and 2025 (in thousands):

The Company's performance obligations are transferred to customers at a point in time. The Company didnot have any material contract assets or contract liabilities on the balance sheet as of March 31, 2026. Revenues related to commercial vehicle sales, parts sales, commercial vehicle repair service, finance and most other revenues are related to the Truck Segment.

9–** Leases**

Lease of Vehicles as Lessor

The Company primarily leases commercial vehicles that the Company owns to customers over periods of one to ten years. The Company does not separate lease and nonlease components. Nonlease components typically consist of maintenance and licensing for the commercial vehicle. The variable nonlease components are generally based on mileage. Some leases contain an option for the lessee to purchase the commercial vehicle at the end of the lease term.

The Company’s policy is to depreciate its lease and rental fleet using a straight-line method over each customer’s contractual lease term. The lease unit is depreciated to a residual value that approximates fair value at the expiration of the lease term. This policy results in the Company realizing reasonable gross margins while the unit is in service and a corresponding gain or loss on sale when the unit is sold at the end of the lease term.

Lease and rental income during the three months ended March 31, 2026 and March 31, 2025 consisted of the following (in thousands):

10–** Accumulated Other Comprehensive Income (Loss)**

The following table shows the components of accumulated other comprehensive income (loss) (in thousands):

The functional currency of the Company’s foreign subsidiary, RTC Canada, is its local currency. Results of operations of RTC Canada are translated into USD using the average exchange rates monthly during the year. The assets and liabilities of RTC Canada are translated into USD using the exchange rates in effect on the balance sheet date. The related translation adjustments are recorded in a separate component of stockholders' equity in Accumulated other comprehensive income (loss) and the statements of comprehensive income (loss).

11–** Accounts Receivable and Allowance for Credit Losses**

The Company establishes an allowance for credit losses to present the net amount of accounts receivable expected to be collected. Under ASU No. 2016-13,Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, the Company is required to remeasure expected credit losses for financial instruments held on the reporting date based on historical experience, current conditions, and reasonable forecasts.

Accounts receivable consists primarily of commercial vehicle sales receivables, manufacturers’ receivables and leasing, parts and service sales receivables and other trade receivables. The Company maintains an allowance for credit losses based on the probability of default, its historical rate of losses, aging and current economic conditions. The Company writes off account balances when it has exhausted reasonable collection efforts and determined that the likelihood of collection is remote. These write-offs are charged against the allowance for credit losses.

The following table summarizes the changes in the allowance for credit losses (in thousands):

12–** Acquisition**
