Quarterly Financial Information Disclosure [Abstract]
Interim Financial Statements	Interim Financial Statements Nature of Business NN, Inc., a Delaware corporation, is a diversified industrial company that combines advanced engineering and production capabilities with in-depth materials science expertise to design and manufacture high-precision components and assemblies for a variety of end markets on a global basis. As of June 30, 2026, we had 27 facilities in North America, South America, Europe and China. As used in this Quarterly Report on Form 10-Q (this “Quarterly Report”), the terms “NN,” the “Company,” “we,” “our,” or “us” refer to NN, Inc. and its subsidiaries. Basis of Presentation The accompanying condensed consolidated financial statements have not been audited. The Condensed Consolidated Balance Sheet as of December 31, 2025, was derived from the audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2025 (the “2025 Annual Report”), which we filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 4, 2026. In management’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary to fairly state our results of operations for the three and six months ended June 30, 2026 and 2025; financial position as of June 30, 2026 and December 31, 2025; and cash flows for the six months ended June 30, 2026 and 2025, on a basis consistent with our audited consolidated financial statements. These adjustments are of a normal recurring nature and are, in the opinion of management, necessary to state fairly our financial position and operating results for the interim periods. Certain prior period amounts have been reclassified to conform to the current year’s presentation. Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted from the unaudited condensed consolidated financial statements presented in this Quarterly Report. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and accompanying notes included in the 2025 Annual Report. The results for the three and six months ended June 30, 2026, are not necessarily indicative of results for the year ending December 31, 2026, or any other future periods. Except for per share data or as otherwise indicated, all U.S. dollar amounts and share counts presented in the tables in these Notes to Condensed Consolidated Financial Statements are in thousands. Accounting Standards Recently Adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which requires additional annual income tax disclosures. These include a tabular rate reconciliation comprised of eight specific categories, the disaggregation of income taxes paid between federal, state, and foreign jurisdictions, and to disaggregate income from continuing operations before income tax expense and income tax expense from continuing operations between domestic and foreign. ASU 2023-09 eliminates the disclosure of the nature and estimate of reasonably possible changes to unrecognized tax benefits in the next 12 months or that an estimated range cannot be made. We adopted ASU 2023-09 for the year ended December 31, 2025. 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” (“ASU 2025-05”), which simplifies how entities measure expected credit losses on current accounts receivable and current contract assets arising from transactions accounted for under ASC 606. This update provides a practical expedient that allows entities to assume that current conditions as of the balance sheet date will remain unchanged for the remaining life of the asset when estimating credit losses. ASU 2025-05 became effective for fiscal years beginning on or after December 15, 2025. We have adopted the practical expedient effective for the current fiscal year noting that it does not have a material impact on the Company’s financial statements. Accounting Standards Not Yet Adopted In November 2024, the FASB issued ASU 2024-03, “Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” (“ASU 2024-03”), which requires disaggregated disclosures of certain categories of expenses that are included in income statement line items. ASU 2024-03 is effective for fiscal years beginning on or after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Companies may early adopt and can apply the guidance prospectively or retrospectively. We have not yet determined the potential impact of adopting this standard. Assets Held for Sale During the year ended December 31, 2025, we ceased production activity at our Mobile Solutions plant in Dowagiac, Michigan. The assets that we own have been classified as held for sale as of June 30, 2026 as we are actively marketing the property and equipment for sale. The net book value of remaining assets held for sale of $1.0 million is included in “Other current assets” on the Condensed Consolidated Balance Sheets as of June 30, 2026.
