Such financial information is not a comprehensive statement of the Company’s financial results for the period and should not be viewed 38 168 as a substitute for full financial statements. The financial information is not necessarily indicative of any future period, and actual results may differ materially. The financial information should be read together with any relevant risk factors and forward-looking statements, and has been prepared by, and is the responsibility of, the Company’s management. 239 249 NON-GAAP FINANCIAL MEASURES, SEC REGULATION G GAAP RECONCILIATIONS 129 205 5 Some of the financial information and data contained in this presentation, such as Adjusted EBITDA, Pro Forma Adjusted EBITDA, Free Cash Flow, Net Working Capital, Adjusted Revenue, Adjusted EBITDA Margin, Free Cash Flow Conversion, Return on Net Working Capital (“RONWC”) and 35 167 Total Net Leverage Ratio have not been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The Company believes that these non-GAAP financial measures provide useful information to management and investors regarding certain financial and business trends 213 238 relating to DSG’s financial condition and results of operations. DSG does not consider non-GAAP measures to be an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is they may exclude significant expense and 213 238 income items that are required by GAAP to be recognized in our consolidated financial statements. In addition, they reflect the exercise of management’s judgment about which expense and income items are excluded or included (including on a pro forma basis) in determining these non-GAAP 6 214 239 financial measures. The presentation of these non-GAAP financial measures is not meant to be considered in isolation or as a substitute for results or guidance prepared and presented in accordance with GAAP. A reconciliation of the non-GAAP financial measures to the nearest comparable GAAP financial measures is contained in the appendix. 30 146 CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS 124 213 Hyperlink This presentation contains certain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934, as amended, and the “safe-harbor” provisions under the Private Securities Litigation Reform Act of 153 234 1995, that involve risks and uncertainties. The terms “aim,” “anticipate,” “believe,” “contemplates,” “continues,” “could,” “ensure,” “estimate,” “expect,” “forecasts,” “if,” “intend,” “likely,” “may,” “might,” “objective,” “outlook,” “plan,” “positioned,” “potential,” “predict,” “probable,” “project,” “shall,” “should,” 0 98 “strategy,” “will,” “would,” and variations of them and other words and terms of similar meaning and expression (and the negatives of such words and terms) are intended to identify forward-looking statements. Followed 80 205 Forward-looking statements can also be identified by the fact that they do not relate strictly to historical or current facts. Such forward-looking statements are based on current expectations and involve inherent risks, uncertainties and assumptions, including factors that could delay, divert or change Hyperlink 117 255 any of them, and could cause actual outcomes to differ materially from current expectations. DSG can give no assurance that any goal or plan set forth in forward-looking statements can be achieved and DSG cautions readers not to place undue reliance on such statements. DSG undertakes no obligation to release publicly any revisions to forward-looking statements as a result of new information, future events or otherwise. Each forward-looking statement speaks only as of the date on which such statement is made, and DSG undertakes no obligation to update any such statement to TABLE reflect events or circumstances arising after such date. Actual results may differ materially from those projected as a result of certain risks and uncertainties. Factors that could cause or contribute to such differences or that might otherwise impact DSG’s business, financial condition and results of operations include the risks that potential acquisitions may not be consummated on the terms currently contemplated, or at all, and that DSG may encounter difficulties integrating the business of DSG with the business of other companies that DSG has combined with or may otherwise combine 50 with and that certain assumptions with respect to such business or transactions, including whether the acquisition would be accretive to DSG and any cost savings and synergies, could prove to be inaccurate. Certain risks associated with DSG’s business are also discussed from time to time in the Lines 56 reports DSG files with the Securities and Exchange Commission, including the Company’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K or other reports the Company may file from time to time with the Securities and Exchange Commission, 62 which should be reviewed carefully.

C O N F I D E N T I A L COLOR PALETTE Text 50 56 62 Executive Summary Title bar/Bullets 68 87 128 ACCENTS ⚫ Distribution Solutions Group, Inc. (“DSG” or the “Company”) is a best-in-class global specialty distribution company providing high-touch, value-added distribution solutions to the 2 85 25 141 Maintenance, Repair and Operations (“MRO”), Original Equipment Manufacturer (“OEM”) and Industrial Technologies markets 1 70 250 1 ⚫ For the TTM period ended June 30, 2026, the Company generated revenue and Pro Forma Adjusted EBITDA of $2.05B and $195M, respectively 68 173 87 185 2 ⚫ On July 15, 2026, LKCM Headwater Investments, LLC (“LKCM”), the majority shareholder of DSG, entered into a definitive merger agreement to acquire all outstanding 128 211 shares of DSG common stock not already owned by LKCM and its affiliates (~21% minority purchase) (the “Share Acquisition”) for $35.00 per share 142 210 169 221 3 216 239 ⚫ The Share Acquisition is expected to be funded with a portion of the $700M of new Senior Notes due 2032 (the “Notes”) and $140M of new LKCM Equity (the “Equity 255 255 Financing”, and together with the Share Acquisition and the Notes, the “Transaction”) 196 231 4 38 168 ⚫ Along with the Equity Financing and in addition to funding the Share Acquisition, proceeds from the Notes will be used to repay a portion of outstanding indebtedness, pay related fees 239 249 and expenses, and for general corporate purposes including future acquisitions 129 205 5 35 167 ⚫ In addition to the Company’s acquisition of American Fasteners Corp. (“AFC”) on September 1, 2026 for a cash purchase price of ~$44M (the “AFC Acquisition”), DSG also expects in 213 238 the near-term to enter into a definitive purchase agreement to acquire a distribution company serving the MRO market (the “Near-Term Target Company”) for an expected purchase 213 238 6 214 239 2 price of ~$145M (the “Potential Near-Term Acquisition”). DSG funded the AFC Acquisition under its Revolving Credit Facility and, if the Potential Near-Term Acquisition is 30 146 consummated before the Share Acquisition, expects to fund the Potential Near-Term Acquisition with borrowings under its Revolving Credit Facility and available cash 124 213 Hyperlink 1,3 4 4 153 234 – For the TTM period ended June 30, 2026, DSG estimates AFC and the Near-Term Target Company generated Pro Forma Adjusted EBITDA of ~$6M and ~$15M , respectively 0 98 Followed⚫ The Company is also currently evaluating five separate acquisitions (collectively, the “Additional Potential Acquisitions” and together with the Potential Near-Term Acquisition, the 80 205 Hyperlink 117 255 “Potential Acquisitions”), including four distribution companies serving the OEM market and one distribution company serving the Industrial Technologies market 5 TABLE – Expected aggregate consideration for the Additional Potential Acquisitions is in the range of $460M to $510M , which may be funded with available cash, debt, equity consideration 50 or any combination thereof Lines 56 62 4 1,3 ⚫ DSG estimates that AFC and the target companies of the Potential Acquisitions would contribute ~$74M of Pro Forma Adjusted EBITDA on a combined basis as of the TTM period 6 68 ended June 30, 2026. LKCM has separately estimated incremental potential combined cost savings and synergies of ~$16M Highlights 87 128 1 7 ⚫ Pro forma for the Transaction, Total Net Leverage Ratio is expected to be 4.5x , with the Company remaining highly focused on returning to its 3.5x – 4.0x long-term target after executing on its strategic Potential Acquisitions (1) (2) Note: Pro Forma Adjusted EBITDA and Total Net Leverage Ratio are non-GAAP financial measures. See the Appendix of this presentation for reconciliations to the most directly comparable GAAP financial measures; While we expect to enter into a final definitive agreement for the Potential Near-Term Acquisition soon, there can be no assurance in this regard. Even if we enter into a definitive agreement for the Potential Near-Term Acquisition, the consummation of such acquisition will be subject to a number of conditions to closing, and there can be no assurance that such conditions will be satisfied, that the (3) (4) Potential Near-Term Acquisition will be consummated on the terms currently contemplated, or at all; Calculated on a basis substantially consistent with Pro Forma Adjusted EBITDA in this presentation; Figures are based on the TTM period ended June 30, 2026 and are based on unaudited financial information (5) provided by the target companies and do not give effect to any cost savings or synergies; As of the date of this presentation, DSG has not entered into a definitive agreement to consummate any of the Additional Potential Acquisitions. The Additional Potential Acquisitions are at various stages of evaluation and remain subject to ongoing due diligence and negotiation, including with respect to valuation and other material terms and the possibility of competing offers. Accordingly, there can be no assurance that definitive agreements will be entered into with respect to any or all of the Additional Potential Acquisitions or that (6) any Additional Potential Acquisitions will be consummated on the terms currently contemplated, or at all; This estimate has not been independently validated or adopted by DSG. Any such potential cost savings and synergies are inherently uncertain and depend on numerous assumptions, including assumptions (7) regarding the consummation and timing of the Potential Acquisitions, integration, costs incurred in connection with the integration of AFC, the Potential Acquisitions and other execution risks; Excludes the impact of the AFC Acquisition and the Potential Acquisitions 4

Since that date and through [09/01/2026], DSG has drawn an additional $50.4M to finance, among other things, the Company’s acquisition of AFC for total outstanding borrowings under the Revolving Credit Facility of $100.8M. The As-Adjusted column does not reflect the repayment of such additional borrowings; If the Company enters into a definitive agreement for the Potential Near-Term Acquisition and consummates the acquisition prior to consummation of the Share Acquisition, the Company anticipates that the cash purchase price of ~$145M will be funded with borrowings under its Revolving Credit Facility (2) (3) (4) and available cash; Represents $0.8M of debt under a Revolving Credit Facility; Pro Forma Adjusted EBITDA is a non-GAAP financial measure. See the Appendix of this presentation for a reconciliation to the most directly comparable GAAP financial measure; Pro Forma Adjusted EBITDA in the As-Adjusted column includes an estimated $5.2M of public company cost avoidance as a result of the completion of the Share Acquisition 5

The Additional Potential Acquisitions are at various stages of evaluation and remain subject to ongoing due diligence and negotiation, including with respect to valuation and other material terms and the possibility of competing offers.

Any such potential cost savings and synergies are inherently uncertain and depend on numerous assumptions, including assumptions regarding the consummation and timing of the Potential Acquisitions, integration, costs incurred in connection with the integration of AFC, the Potential Acquisitions and other execution risks 19

Estimates of results are inherently uncertain and subject to change, and we do not undertake any obligation to update this information. We have provided ranges, rather than specific amounts, because our normal reporting processes have not been completed for the quarter.
