Accounting Policies [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation Organization Effective May 5, 2022, Distribution Solutions Group, Inc. ("DSG"), a Delaware corporation, changed its corporate name from “Lawson Products, Inc.” to “Distribution Solutions Group, Inc.” DSG is a global specialty distribution company providing value added distribution solutions to the maintenance, repair and operations ("MRO"), original equipment manufacturer ("OEM") and industrial technology markets. DSG has three principal operating companies: Lawson Products, Inc. ("Lawson"), TestEquity Acquisition, LLC ("TestEquity") and 301 HW Opus Holdings, Inc., conducting business as Gexpro Services ("Gexpro Services"). The complementary distribution operations of Lawson, TestEquity and Gexpro Services were combined for the purpose of creating a specialty distribution company. A summary of the Mergers (as defined below), including the legal entities party to the transactions and the stock consideration, is presented below. Unless the context requires otherwise, references in this Quarterly Report on Form 10-Q to “DSG”, the “Company”, "we", "our" or "us" refer to the holding company, Distribution Solutions Group, Inc., and all entities consolidated in the accompanying unaudited condensed consolidated financial statements. Business Combination Background On December 29, 2021, DSG entered into an: • Agreement and Plan of Merger (the “TestEquity Merger Agreement”) by and among (i) LKCM TE Investors, LLC, a Delaware limited liability company (the “TestEquity Equityholder”), (ii) TestEquity Acquisition, LLC, a Delaware limited liability company and a wholly-owned subsidiary of the TestEquity Equityholder (“TestEquity”), (iii) DSG and (iv) Tide Sub, LLC, a Delaware limited liability company and a wholly-owned subsidiary of DSG (“Merger Sub 1”), pursuant to the terms and subject to the conditions of which the parties agreed, among other things, that Merger Sub 1 would merge with and into TestEquity, with TestEquity surviving the merger as a wholly-owned subsidiary of DSG (the “TestEquity Merger”); and • Agreement and Plan of Merger (the “Gexpro Services Merger Agreement” and, together with the TestEquity Merger Agreement, the “Merger Agreements”) by and among (i) 301 HW Opus Investors, LLC, a Delaware limited liability company (the “Gexpro Services Stockholder”), (ii) 301 HW Opus Holdings, Inc., a Delaware corporation and a wholly-owned subsidiary of the Gexpro Services Stockholder (“Gexpro Services”), (iii) DSG and (iv) Gulf Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of DSG (“Merger Sub 2”), pursuant to the terms and subject to the conditions of which the parties agreed, among other things, that Merger Sub 2 would merge with and into Gexpro Services, with Gexpro Services surviving the merger as a wholly-owned subsidiary of DSG (the “Gexpro Services Merger” and, together with the TestEquity Merger, the “Mergers”). Each outstanding share of TestEquity and Gexpro Services common stock outstanding immediately prior to the closing of the Merger can be derived by converted into approximately 0.3618 shares and 0.7675 shares, respectively, of Company common stock. Completion of the TestEquity Merger On April 1, 2022, (the "Merger Date"), the TestEquity Merger was consummated pursuant to the TestEquity Merger Agreement. In accordance with and under the terms of the TestEquity Merger Agreement, at the closing of the TestEquity Merger, DSG: (i) issued to the TestEquity Equityholder 3,300,000 shares of DSG common stock, (ii) on behalf of TestEquity, paid certain indebtedness of TestEquity and (iii) on behalf of TestEquity, paid certain transaction expenses of TestEquity. The TestEquity Merger Agreement provides that an additional 700,000 shares of DSG common stock (the “TestEquity Holdback Shares”) may be issued to the TestEquity Equityholder or forfeited in accordance with two earnout provisions of the TestEquity Merger Agreement. The amount of TestEquity Holdback Shares issuable under the first earnout opportunity is based on, among other factors, the consummation of a certain additional acquisition by TestEquity during the period beginning after December 29, 2021 and ending 90 days after the Merger Date. If any TestEquity Holdback Shares remain after the calculation of the first earnout opportunity, there is a second earnout opportunity based on, among other factors, the increase in TestEquity EBITDA (as defined in the TestEquity Merger Agreement) in calendar year 2022 over calendar year 2021 subject to the calculations within the TestEquity Merger Agreement. As of June 30, 2022, 700,000 TestEquity Holdback Shares are expected to be issued under the first earnout opportunity due to the consummation of the certain additional acquisition as referenced in the TestEquity Merger Agreement and were remeasured and reclassified to equity at April 29, 2022 when the additional acquisition was consummated. Refer to Note 11 - Earnout Derivative Liability for information about the earnout derivative liability related to the TestEquity Holdback Shares. Completion of the Gexpro Services Merger On the Merger Date, the Gexpro Services Merger was consummated pursuant to the Gexpro Services Merger Agreement. In accordance with and under the terms of the Gexpro Services Merger Agreement, at the closing of the Gexpro Services Merger, DSG: (i) issued to the Gexpro Services Stockholder 7,000,000 shares of DSG common stock, (ii) on behalf of Gexpro Services, paid certain indebtedness of Gexpro Services and (iii) on behalf of Gexpro Services, paid certain specified transaction expenses of Gexpro Services. The Gexpro Services Merger Agreement provides that an additional 1,000,000 shares of DSG common stock (the “Gexpro Services Holdback Shares”) may be issued to the Gexpro Services Stockholder or forfeited in accordance with two earnout provisions of the Gexpro Services Merger Agreement. The amount of Gexpro Services Holdback Shares issuable under the first earnout opportunity is based on, among other factors, the consummation of one or more of three certain additional acquisitions by Gexpro Services during the period beginning after December 29, 2021 and ending 90 days after the Merger Date. If any Gexpro Services Holdback Shares remain after the calculation of the first earnout opportunity, there is a second earnout opportunity based on, among other factors, the increase in Gexpro Services EBITDA (as defined in the Gexpro Services Merger Agreement) in calendar year 2022 over calendar year 2021 subject to the calculations within the Gexpro Services Merger Agreement. As of April 1, 2022, approximately 538,000 Gexpro Services Holdback Shares were expected to be issued under the first earnout opportunity due to the consummation of the certain additional acquisitions which were completed prior to the Merger Date. The fair value of the remaining 462,000 Gexpro Services Holdback Shares available under the second earnout opportunity are included in Earnout derivative liability in the Unaudited Condensed Consolidated Balance Sheets. Final issuance of the Gexpro Services Holdback Shares under the second earnout opportunity is subject to certain terms and conditions as specified in the Gexpro Services Merger Agreement. Refer to Note 11 - Earnout Derivative Liability for information about the earnout derivative liability related to the Gexpro Services Holdback Shares. TestEquity and Gexpro Services were treated as a combined entity as the accounting acquirer for financial reporting purposes, and DSG was identified as the accounting acquiree. Accordingly, periods prior to the Merger Date reflect the results of operations and financial position of TestEquity and Gexpro Services on a consolidated basis, and the results of operations of DSG's legacy Lawson business are only included subsequent to the April 1, 2022 Merger Date. Nature of Operations A summary of the nature of operations for each of DSG's operating companies is presented below. Information regarding DSG's reportable segments is presented in Note 19 - Segment Information. Lawson sells and distributes specialty products to the industrial, commercial, institutional and government MRO market and uses sales representatives to provide Vendor Managed Inventory ("VMI") services to Lawson's customers. Through The Bolt Supply House business, customers in Western Canada have access to products at 14 branch locations in Alberta, Saskatchewan, Manitoba and British Columbia, Canada. Under its Kent Automotive brand, Lawson provides collision and mechanical repair products to the automotive aftermarket. Lawson ships from several strategically located distribution centers to customers in all 50 states, Puerto Rico, Canada, Mexico, and the Caribbean. TestEquity is a distributor of test and measurement equipment and solutions, electronic production supplies, and tool kits from its leading manufacturer partners supporting the technology, aerospace, defense, automotive, electronics, education, and medical industries. TestEquity operates primarily through four brands, TestEquity, TEquipment, Jensen Tools and Techni-Tool. TestEquity also designs a full line of environmental test chambers. Gexpro Services is a provider of supply chain solutions, specializing in developing and implementing VMI and kitting programs to high-specification manufacturing customers. Gexpro Services provides critical products and services to customers throughout the lifecycle of highly technical Original Equipment Manufacturer (OEM) products. Basis of Presentation and Consolidation The Mergers were accounted for as a reverse merger under the acquisition method of accounting in accordance with the accounting guidance for reverse acquisitions as provided in Accounting Standards Codification ("ASC") 805, Business Combinations ("ASC 805"). Under this guidance, TestEquity and Gexpro Services were treated as a combined entity as the accounting acquirer for financial reporting purposes, and DSG was identified as the accounting acquiree. This determination was primarily made as TestEquity and Gexpro Services were under the common control of an entity that owns a majority of the voting rights of the combined entity, and therefore, only DSG experienced a change in control. Accordingly, the unaudited condensed consolidated financial statements as of June 30, 2022 and December 31, 2021 and for the three and six months ended June 30, 2022 and 2021 reflect the results of operations and financial position of TestEquity and Gexpro Services on a consolidated basis, and the results of operations of DSG's legacy Lawson business are only included subsequent to the April 1, 2022 Merger Date. The Company and its consolidated subsidiaries, except for Gexpro Services, operate on a calendar year-end. Gexpro Services operates on a calendar year-end for annual reporting purposes. However, quarterly financial statements for Gexpro Services are prepared on financial close dates that may differ from that of the Company. The consolidated financial statement impact of the two day difference arising from the different period ends for the quarter ended June 30, 2022 was not material. The Company utilizes the exchange rates in effect at Gexpro Services’ reporting date and the appropriate weighted-average rate for its fiscal reporting period. The accompanying unaudited condensed consolidated financial statements of DSG have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not contain all disclosures required by GAAP for complete consolidated financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the TestEquity Acquisition, LLC and 301 HW Opus Holdings, Inc. audited consolidated financial statements and accompanying notes included in the Company's Current Report on Form 8-K/A filed with the U.S. Securities and Exchange Commission ("SEC") on June 15, 2022, and the Lawson Products, Inc. audited consolidated financial statements and accompanying notes included in DSG's Annual Report on Form 10-K filed for the year ended December 31, 2021. All normal recurring adjustments have been made that are necessary to fairly state the results of operations for the interim periods. Operating results for the three and six month periods ended June 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022.
