Nature of Operations and Basis of Presentation	Note 1 – Nature of Operations and Basis of Presentation Organization Distribution Solutions Group, Inc. ("DSG"), a Delaware corporation, 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., an Illinois corporation ("Lawson"), TestEquity Acquisition, LLC, a Delaware limited liability company ("TestEquity"), and 301 HW Opus Holdings, Inc., a Delaware corporation conducting business as Gexpro Services ("Gexpro Services"). The complementary distribution operations of Lawson, TestEquity and Gexpro Services were combined on April 1, 2022 to create 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. Combination with TestEquity and Gexpro Services 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, which was a wholly-owned subsidiary of the TestEquity Equityholder, (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 • an 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) Gexpro Services, which was a wholly-owned subsidiary of the Gexpro Services Stockholder, (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”). At the closing of the Mergers, each outstanding share of TestEquity and Gexpro Services common stock outstanding immediately prior to the closing of the Mergers was converted into approximately 0.3618 shares and 0.7675 shares, respectively, of DSG common stock, based on the ratio of outstanding shares of each entity immediately prior to the Mergers to the number of shares of DSG common stock acquired in the Mergers. 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 the TestEquity Merger Agreement, Merger Sub 1 merged with and into TestEquity, with TestEquity surviving as a wholly-owned subsidiary of DSG. In accordance with and under the terms of the TestEquity Merger Agreement, in connection with the closing of the TestEquity Merger on the Merger Date, 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 provided that up to an additional 700,000 shares of DSG common stock would be potentially issuable to the TestEquity Equityholder in accordance with, and subject to the terms and conditions of, the earnout provisions of the TestEquity Merger Agreement. On March 20, 2023, DSG issued 700,000 shares of DSG common stock to the TestEquity Equityholder (the "TestEquity Holdback Shares") pursuant to the terms of the earnout provisions of the TestEquity Merger Agreement. The TestEquity Holdback Shares issued represented the maximum number of additional shares that could be issued under the TestEquity Merger Agreement, and no further shares are available for issuance, and no additional shares will be issued, in connection with the TestEquity Merger Agreement. Refer to Note 8 – 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 the Gexpro Services Merger Agreement, Merger Sub 2 merged with and into Gexpro Services, with Gexpro Services surviving as a wholly-owned subsidiary of DSG. In accordance with and under the terms of the Gexpro Services Merger Agreement, in connection with the closing of the Gexpro Services Merger on the Merger Date, 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 provided that up to an additional 1,000,000 shares of DSG common stock would be potentially issuable to the Gexpro Services Stockholder in accordance with, and subject to the terms and conditions of, the earnout provisions of the Gexpro Services Merger Agreement. On March 20, 2023, DSG issued 1,000,000 shares of DSG common stock to the Gexpro Services Stockholder (the “Gexpro Services Holdback Shares”) pursuant to the terms of the earnout provisions of the Gexpro Services Merger Agreement. The Gexpro Services Holdback Shares issued represented the maximum number of additional shares that could be issued under the Gexpro Services Merger Agreement, and no further shares are available for issuance, and no additional shares will be issued, in connection with the Gexpro Services Merger Agreement. As of April 1, 2022, approximately 538,000 of the Gexpro Services Holdback Shares had been expected to be issued under the first earnout opportunity in the Gexpro Services Merger Agreement based on certain earnout metrics related to the consummation of certain additional acquisitions which were completed prior to the Merger Date. Under the Gexpro Services Merger Agreement, if any Gexpro Services Holdback Shares remained after the calculation of the first earnout opportunity, there was a second earnout opportunity under the Gexpro Services Merger Agreement based on certain earnout performance metrics. On March 20, 2023, all 1,000,000 Gexpro Services Holdback Shares were issued under the earnout opportunities. The incremental 462,000 Gexpro Services Holdback Shares that were issued in excess of the 538,000 Gexpro Services Holdback Shares that were originally expected to be issued had been remeasured at fair value immediately prior to and reclassified to equity at December 31, 2022. Refer to Note 8 – Earnout Derivative Liability for information about the earnout derivative liability related to the Gexpro Services Holdback Shares. Accounting for the Mergers 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 April 1, 2022 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. For more information about the Mergers, refer to Note 3 – Business Acquisitions. 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 16 – Segment Information. Lawson is a distributor of specialty products and services to the industrial, commercial, institutional and government maintenance, repair and operations market. 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. Gexpro Services is a global supply chain solutions provider, specializing in developing and implementing vendor managed inventory and kitting programs to high-specification manufacturing customers. 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 for the three months ended March 31, 2023 and 2022 reflect the results of operations of TestEquity and Gexpro Services on a consolidated basis, and the results of operations of DSG's legacy Lawson business are included only in the unaudited condensed consolidated financial statements for the three months ended March 31, 2023 for activity subsequent to the April 1, 2022 Merger Date. The unaudited condensed consolidated financial statements as of March 31, 2023 and December 31, 2022 reflect the financial position of TestEquity, Gexpro Services and DSG's legacy Lawson business on a consolidated basis. 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 one day difference arising from the different period ends for the quarter ended March 31, 2023 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 DSG's audited consolidated financial statements and accompanying notes included in its Annual Report on Form 10-K for the year ended December 31, 2022 filed with the U.S. Securities and Exchange Commission ("SEC") and the Lawson Products, Inc. unaudited condensed consolidated financial statements and accompanying notes included in DSG’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2022. 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 month period ended March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023.
