Organization, Consolidation and Presentation of Financial Statements [Abstract]

Schneider National, Inc. and its wholly owned subsidiaries (together “Schneider,” the “Company,” “we,” “us,” or “our”) are among the leading providers of multimodal transportation and logistics solutions in North America. We provide safe, reliable, and innovative truckload, intermodal, and logistics services to a diverse group of customers throughout the continental U.S., Canada, and Mexico.

Principles of Consolidation and Basis of Presentation

The accompanying unaudited interim consolidated financial statements have been prepared in conformity with GAAP and the rules and regulations of the SEC applicable to quarterly reports on Form 10-Q. Therefore, these consolidated financial statements and footnotes do not include all disclosures required by GAAP for annual financial statements and should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2025.

In the opinion of management, these statements reflect all adjustments (consisting only of normal, recurring adjustments) necessary for the fair presentation of our financial results for the interim periods presented.
