BlueLinx (NYSE: BXC) First Quarter 2019 May 8, 2019 Conference Call Presentation

Notes To Investors Forward-Looking Statements. This presentation contains forward-looking statements. Forward-looking statements include, without limitation, any statement that predicts, forecasts, indicates or implies future results, performance, liquidity levels or achievements, and may contain the words “believe,” “anticipate,” “expect,” “estimate,” “intend,” “project,” “plan,” “will be,” “will likely continue,” “will likely result” or words or phrases of similar meaning. The forward-looking statements in this presentation include statements about the timing of completion of the integration of Cedar Creek; the timing and achievement of run-rate synergies from the acquisition of Cedar Creek; our plans to achieve further efficiency gains in overlap markets; our strategic initiatives; the outlook for the housing market and interest rates; our liquidity; our expectations for commodity prices in the second quarter; expected costs to achieve run-rate synergies from the Cedar Creek acquisition; our real estate monetization efforts and expected proceeds from the sale of owned real estate; our expected annual uses of cash and potential cash available for debt reduction; and our ability to utilize net operating losses. Forward-looking statements are based on estimates and assumptions made by our management that, although believed by us to be reasonable, are inherently uncertain. Forward-looking statements involve risks and uncertainties that may cause our business, strategy, or actual results to differ materially from the forward- looking statements. These risks and uncertainties include those discussed under the heading “Risk Factors” in Item 1A of our Annual Report on Form 10-K for the year ended December 29, 2018, and those discussed in our Quarterly Reports on Form 10-Q and in our periodic reports filed with the Securities and Exchange Commission from time to time. We operate in a changing environment in which new risks can emerge from time to time. It is not possible for management to predict all of these risks, nor can it assess the extent to which any factor, or a combination of factors, may cause our business, strategy, or actual results to differ materially from those contained in forward-looking statements. Factors that may cause these differences include, among other things: our ability to integrate and realize anticipated synergies from acquisitions; loss of material customers, suppliers, or product lines in connection with acquisitions; our indebtedness and its related limitations; sufficiency of cash flows and capital resources; changes in interest rates; fluctuations in commodity prices; adverse housing market conditions; disintermediation by customers and suppliers; changes in prices, supply and/or demand for our products; inventory management; competitive industry pressures; industry consolidation; product shortages; loss of and dependence on key suppliers and manufacturers; new tariffs; our ability to monetize real estate assets; our ability to successfully implement our strategic initiatives; fluctuations in operating results; sale-leaseback transactions and their effects; real estate leases; exposure to product liability claims; changes in our product mix; petroleum prices; information technology security and business interruption risks; litigation and legal proceedings; natural disasters and unexpected events; activities of activist stockholders; labor and union matters; limits on net operating loss carryovers; pension plan assumptions and liabilities; risks related to our internal controls; retention of associates and key personnel; federal, state, local and other regulations, including environmental laws and regulations; and changes in accounting principles. Given these risks and uncertainties, we caution you not to place undue reliance on forward-looking statements. We expressly disclaim any obligation to update or revise any forward-looking statement as a result of new information, future events or otherwise, except as required by law. Non-GAAP Financial Measures and Supplementary Financial Information. BlueLinx reports its financial results in accordance with accounting principles generally accepted in the United States (“GAAP”). We also believe that presentation of certain non-GAAP measures, such as Adjusted EBITDA, as well as GAAP-based and non-GAAP supplemental financial measures, may be useful to investors and may provide a more complete understanding of the factors and trends affecting the business than using reported GAAP results alone. Explanations of these non-GAAP measures and these GAAP-based and non-GAAP supplemental financial measures are included in the accompanying Appendix to this presentation. And any non-GAAP measures used herein are reconciled herein or in the financial tables in the Appendix to their most directly comparable GAAP measures. We caution that non-GAAP measures and supplemental financial measures should be considered in addition to, but not as a substitute for, our reported GAAP results. Immaterial Rounding Differences. Immaterial rounding adjustments and differences may exist between slides, press releases, and previously issued presentations. This presentation and the associated remarks made during this conference call are integrally related and are intended to be presented and understood together. 2

Appendix

Non-GAAP And Supplementary Financial Measures BlueLinx reports its financial results in accordance with GAAP, but we also believe that presentation of certain non-GAAP measures, as well as GAAP-based and non-GAAP supplemental financial measures, may be useful to investors and may provide a more complete understanding of the factors and trends affecting the business than using reported GAAP results alone. We caution that non-GAAP measures and supplemental financial measures should be considered in addition to, but not as a substitute for, our reported GAAP results. Adjusted EBITDA and Pro forma Adjusted EBITDA. We define Adjusted EBITDA as an amount equal to net income plus interest expense and all interest expense related items, income taxes, depreciation and amortization, and further adjusted for certain non-cash items and other special items, including compensation expense from share based compensation, one-time charges associated with the legal, consulting, and professional fees related to the Cedar Creek acquisition, and gains on sales of properties including amortization of deferred gains. We present Adjusted EBITDA because it is a primary measure used by management to evaluate operating performance and, we believe, helps to enhance investors’ overall understanding of the financial performance and cash flows of our business. We believe Adjusted EBITDA is helpful in highlighting operating trends. We also believe that Adjusted EBITDA is frequently used by securities analysts, investors and other interested parties in their evaluation of companies, many of which present an Adjusted EBITDA measure when reporting their results. However, Adjusted EBITDA is not a presentation made in accordance with GAAP, and is not intended to present a superior measure of the financial condition from those determined under GAAP. Adjusted EBITDA, as used herein, is not necessarily comparable to other similarly titled captions of other companies due to differences in methods of calculation. Pro forma Adjusted EBITDA for any period is calculated in the same manner as Adjusted EBITDA, but also combines the historical results of BlueLinx for the three months ended March 31, 2018, with the historical results of Cedar Creek for the three months ended March 31, 2018, giving effect to the Cedar Creek acquisition and related adjustments as if the acquisition occurred on January 1, 2017. Supplemental Financial Measures. We completed the acquisition of Cedar Creek on April 13, 2018. As a result, Cedar Creek’s financial results are only included in the combined company’s reported financial results from the Closing Date forward. To supplement these reported results, we have provided GAAP-based and non-GAAP pro forma financial information of the combined company in this presentation that includes Cedar Creek’s financial results for the relevant periods prior to the Closing Date. This pro forma information combines the historical results of BlueLinx for the three months ended March 31, 2018, with the historical results of Cedar Creek for the three months ended March 31, 2018, giving effect to the Cedar Creek acquisition and related adjustments as if the acquisition occurred on January 1, 2017. 15
