Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Fastenal Company and subsidiaries (the 'Company', 'Fastenal', 'we', 'our', or 'us') have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information. They do not include all information and footnotes required by U.S. GAAP for a complete set of financial statements. However, except as described herein, there has been no material change in the information disclosed in the Notes to Consolidated Financial Statements included in our consolidated financial statements as of and for the year ended December 31, 2024. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair statement have been included.

Recently Issued Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-09, Improvements to Income Tax Disclosures (Topic 740), which establishes new income tax disclosure requirements in addition to modifying and eliminating certain existing requirements. The new guidance requires consistent categorization and greater disaggregation of information in the rate reconciliation, as well as further disaggregation of income taxes paid. This change is effective for annual periods beginning after December 15, 2024. This change will apply on a prospective basis to annual financial statements for periods beginning after the effective date. However, retrospective application in all prior periods presented is permitted. ASU 2023-09 is expected to impact our income tax disclosures beginning with the consolidated financial statements included in the annual report on Form 10-K for the fiscal year ending December 31, 2025, but will have no impact on our results of operations, cash flows, or financial condition.

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses (DISE), which adds new disclosure requirements including the composition of certain income statement expense line items (such as purchases of inventory, employee compensation, and 'other expenses') and a separate disclosure for selling expenses. This change is effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027, however, early adoption is permitted. We are currently evaluating the impact that the adoption of ASU 2024-03 will have on our consolidated financial statements and disclosures and anticipate adoption in our annual report on Form 10-K for the fiscal year ending December 31, 2027.

Revenue Recognition

Revenue Recognition

Net sales include products and shipping and handling charges, net of estimates for product returns and any related sales incentives. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products. All revenue is recognized when or as we satisfy our performance obligations under the contract. We recognize revenue by transferring control of the promised products to the customer, which primarily occurs when products are delivered or picked up by the customer. We recognize revenue for shipping and handling charges at the time the products are delivered to or picked up by the customer. We estimate product returns based on historical return rates. Using probability assessments, we estimate sales incentives expected to be paid over the term of the contract. The majority of our contracts have a single performance obligation and are short-term in nature. Sales taxes and value added taxes in foreign jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales.
