Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation BlueLinx Holdings Inc., including consolidated subsidiaries (collectively, the “Company”), is a leading wholesale distributor of residential and commercial building products in the United States. The Company is a two-step distributor and purchases products from manufacturers and distributes those products to dealers and other suppliers in local markets, who then sell those products to end users. The Company carries a broad portfolio of both branded and private-label stock keeping units (“SKUs”) across two principal product categories: specialty products and structural products. Specialty products include items such as engineered wood, siding, moulding and millwork, outdoor living, specialty lumber and panels, and industrial products. Structural products include items such as lumber, plywood, oriented strand board, rebar, and remesh. The Company also provides a wide range of value-added services and solutions aimed at relieving distribution and logistics challenges for its customers and suppliers, while enhancing their marketing and inventory management capabilities. The Company’s unaudited condensed consolidated financial statements and accompanying notes have been prepared using generally accepted accounting principles in the United States (“GAAP”) and the interim reporting guidance of the U.S. Securities and Exchange Commission (“SEC”). The Company is composed of a single reportable segment for financial reporting purposes. The Company’s consolidated balance sheet as of January 3, 2026 contained herein was derived from the audited consolidated balance sheet included in the Company’s Annual Report on Form 10-K for the fiscal year ended January 3, 2026 (the “2025 Form 10-K”), as filed with the SEC on February 24, 2026. In the opinion of the Company’s management, the unaudited condensed consolidated financial statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair presentation of the Company’s results of operations, financial position, and cash flows for the reporting periods presented. The Company has condensed or omitted certain notes and other information from the unaudited condensed consolidated financial statements presented in this report. Therefore, these condensed financial statements and accompanying notes should be read in conjunction with the Company’s 2025 Form 10-K. The results for the fiscal three months ended April 4, 2026 are not necessarily indicative of results that may be expected for the full fiscal year ending January 2, 2027, or any other interim period. For the fiscal reporting periods included in the unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q, the Company did not have any items of other comprehensive income (loss), nor did the Company have any accumulated other comprehensive income (loss). The Company operates on a 5-4-4 fiscal calendar and its fiscal year ends on the Saturday closest to December 31st of each year and may comprise 53 weeks in certain years. Fiscal 2026 contains 52 weeks and will end on January 2, 2027. Fiscal 2025 contained 53 weeks and ended on January 3, 2026. Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates based on assumptions about current and, for some estimates, future economic and market conditions, which affect reported amounts and related disclosures in the Company’s financial statements. Although current estimates contemplate current and expected future conditions, as applicable, it is reasonably possible that actual conditions could differ from management’s expectations, which could materially affect the Company’s results of operations and financial position. Significant Accounting Policies The Company has made no material changes to its significant accounting policies described in the notes to the consolidated financial statement included in its 2025 Form 10-K. The Company did not adopt any new accounting standards during the fiscal three months ended April 4, 2026. Recent Accounting Pronouncements - Not Yet Adopted Costs and Expenses Disclosures. On November 4, 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”), which establishes new disaggregation disclosure requirements for certain costs and expenses in the notes to the consolidated financial statements. Under the new guidance, an entity must provide details of the components of its expense captions from continuing operations presented on the face of the statement of operations as well as a qualitative description of the amounts remaining that are not separately disaggregated quantitatively. Relevant disclosure categories include purchases of inventory, employee compensation, depreciation and intangible asset amortization. An entity must also disclose the total amount of selling expenses, and in annual reports, its definition thereof. The disclosure of these costs and expenses will be required in addition to and irrespective of their inclusion in other disclosures. ASU 2024-03 will be effective for the Company for the fiscal 2027 annual reporting period and for interim periods beginning in fiscal 2028. The guidance may be applied prospectively or retrospectively. Since this new ASU addresses only disclosures, the Company does not expect its adoption to have any material effects on its financial condition, results of operations or cash flows. The Company is currently evaluating the new disclosures that will be required upon adoption of ASU 2024-03. Accounting for and Disclosure of Software Costs. On September 18, 2025, the FASB issued ASU No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Accounting for and Disclosure of Software Costs (“ASU 2025-06”) to clarify and modernize the accounting for costs related to internal-use software to better address both linear and non-linear development manners. The new guidance removes all references to project stages that are currently in ASC 350-40 and will instead use threshold requirements that entities must apply to decide when to start capitalizing software costs. Specifically, the guidance will require entities to begin capitalizing software costs, including website development costs, when both of the following occur: 1) management authorizes and commits to funding a software project and 2) it is probable that the project will be completed and the software will be used to perform the function intended (referred to as the “probable-to-complete” recognition threshold). ASU 2025-06 is effective for the Company beginning in interim and annual reporting periods in fiscal 2028, and early adoption is permitted which the Company is evaluating. Entities may apply the guidance using a prospective, retrospective, or modified transition approach. However, under the prospective approach, entities would still be required to apply the new guidance to all new costs incurred for all software projects, including in-process projects, as of the date of adoption. ASU 2025-06 also specifies that the disclosures under ASC 360-10 (Property, Plant, and Equipment) apply overall to capitalized software costs accounted for under ASC 350-40, regardless of how those costs are presented in the financial statements. The Company is currently evaluating the impacts that ASU 2025-06 may have on its financial position and results of operations, and such impacts may depend in part on the status and type of any in-process software projects at the time of adoption.
