Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim consolidated financial statements include the accounts of Werner Enterprises, Inc. and its subsidiaries (collectively, the “Company” or “Werner”). Redeemable noncontrolling interest on the consolidated condensed balance sheets represents the portion of a consolidated entity in which we do not have a direct equity ownership. In these notes, the terms “we,” “us,” or “our” refer to Werner Enterprises, Inc. and its subsidiaries. All significant intercompany accounts and transactions relating to these entities have been eliminated. These consolidated financial statements have been prepared in accordance with the U.S. Securities and Exchange Commission (“SEC”) instructions to Form 10-Q and, in the opinion of management, reflect all adjustments, which are all of normal recurring nature, necessary to present fairly the financial condition, results of operations and cash flows for the periods presented in conformity with U.S. generally accepted accounting principles (“GAAP”). These consolidated financial statements do not include all information and footnotes required by GAAP for complete financial statements; although in management’s opinion, the disclosures are adequate so that the information presented is not misleading. Operating results for the three and nine months ended September 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025. In the opinion of management, the information set forth on the accompanying consolidated condensed balance sheets is fairly stated in all material respects in relation to the consolidated balance sheets from which it has been derived. These consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and accompanying notes contained in our 2024 Form 10-K.
Recently Issued Accounting Pronouncements, Not Yet Effective	Recently Issued Accounting Pronouncements, Not Yet Effective In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures, with the objective of enhancing the transparency and decision usefulness of income tax information through income tax disclosure improvements, primarily related to the rate reconciliation and income taxes paid information. The provisions of this update are effective for our annual period ending December 31, 2025, using a prospective approach. We expect the adoption of ASU 2023-09 to impact our disclosures but not our results of operations, cash flows, and financial condition. In November 2024, the FASB issued ASU 2024-03 Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, requiring public business entities to disclose additional information about specific expense categories in the notes to the financial statements at interim and annual reporting periods, including purchases of inventory, employee compensation, depreciation, and intangible asset amortization. The provisions of this update are effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, using either a prospective or retrospective approach. We are evaluating the impact of adopting ASU 2024-03, and we expect this ASU to impact our disclosures but not our results of operations, cash flows, and financial condition. In July 2025, the FASB issued ASU 2025-05 Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides a practical expedient permitting entities to assume that conditions at the balance sheet date remain unchanged for the remaining life of the asset when estimating expected credit losses for current accounts receivable and current contract assets under Topic 606 – Revenue from Contracts with Customers. ASU 2025-05 is effective for annual reporting periods beginning after December 15, 2025, and for interim periods within those annual reporting periods, using a prospective approach. We plan to elect the practical expedient upon the adoption of ASU 2025-05 on January 1, 2026, and we do not expect it to have a material impact to our results of operations, cash flows, and financial condition. In September 2025, the FASB issued ASU 2025-06 Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40), which simplifies the capitalization guidance by removing all references to software development project stages so that the guidance is neutral to different software development methods. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. The amendments in this update permit an entity to apply the new guidance using a prospective, retrospective or modified transition approach. We plan to adopt this ASU for our fiscal year beginning January 1, 2028 using a prospective approach. Although we are evaluating the impact of adopting ASU 2025-06 on our results of operations, cash flows, and financial position, we do not expect a material effect upon adoption.
