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,” “could”, “expect,” “estimate,” “intend,” “may”, “project,” “plan,” “should”, “will”, “will be,” “will likely continue,” “will likely result”, “would” or words or phrases of similar meaning. The forward-looking statements in this presentation include statements about our confidence in the Company’s long-term growth strategy; our ability to capitalize on supplier-led price increases and our value-added services; our areas of focus and management initiatives; the demand outlook for construction materials and expectations regarding new home construction, repair and remodel activity and continued investment in existing and new homes; our positioning for long-term value creation; our efforts and ability to generate profitable growth; our ability to increase net sales in specialty product categories; our ability to generate profits and cash from sales of specialty products; our multi-year capital allocation plans; our ability to manage volatility in wood-based commodities; our improvement in execution and productivity; our efforts and ability to maintain a disciplined capital structure and capital allocation strategy; our ability to maintain a strong balance sheet; our ability to focus on operating improvement initiatives and commercial excellence; and whether or not the Company will continue any share repurchases. Forward-looking statements in this presentation 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 in greater detail in our filings with the Securities and Exchange Commission. 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: housing market conditions; pricing and product cost variability; volumes of product sold; competition; the cyclical nature of the industry in which we operate; consolidation among competitors, suppliers, and customers; disintermediation risk; loss of products or key suppliers and manufacturers; our dependence on international suppliers and manufacturers for certain products; effective inventory management relative to our sales volume or the prices of the products we produce; business disruptions; potential acquisitions and the integration and completion of such acquisitions; information technology security risks and business interruption risks; the ability to attract, train, and retain highly qualified associates and other key personnel while controlling related labor costs; exposure to product liability and other claims and legal proceedings related to our business and the products we distribute; natural disasters, catastrophes, fire, wars or other unexpected events; the impacts of climate change; successful implementation of our strategy; wage increases or work stoppages by our union employees; costs imposed by federal, state, local, and other regulations; compliance costs associated with federal, state, and local environmental protection laws; the effects of epidemics, global pandemics or other widespread public health crises and governmental rules and regulations; fluctuations in our operating results; our level of indebtedness and our ability to incur additional debt to fund future needs; the covenants of the instruments governing our indebtedness limiting the discretion of our management in operating the business; the potential to incur more debt; the fact that we have consummated certain sale leaseback transactions with resulting long-term non-cancelable leases, many of which are or will be finance leases; the fact that we lease many of our distribution centers, and we would still be obligated under these leases even if we close a leased distribution center; inability to raise funds necessary to finance a required repurchase of our senior secured notes; a lowering or withdrawal of debt ratings; changes in our product mix; increases in fuel and other energy prices or availability of third-part freight providers; changes in insurance-related deductible/retention reserves based on actual loss development experience; the possibility that the value of our deferred tax assets could become impaired; changes in our expected annual effective tax rate could be volatile; the costs and liabilities related to our participation in multi-employer pension plans could increase; the risk that our cash flows and capital resources may be insufficient to service our existing or future indebtedness; interest rate risk, which could cause our debt service obligations to increase; and changes in, or interpretation of, 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. Immaterial Rounding Differences. Immaterial rounding adjustments and differences may exist between slides, press releases, and previously issued presentations.

The Company reports its financial results in accordance with GAAP. The Company also believes that presentation of certain non-GAAP 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. Any non-GAAP measures used herein are reconciled to their most directly comparable GAAP measures herein or in the financial tables accompanying this presentation. The Company cautions that non-GAAP measures are not presentations made in accordance with GAAP and are not intended to present superior measures of our financial condition from those measures determined under GAAP. Non-GAAP measures should be considered in addition to, but not as a substitute for, the Company’s reported GAAP results. The Company further cautions that its non-GAAP measures, as used herein, are not necessarily comparable to other similarly titled measures of other companies due to differences in methods of calculation. Adjusted EBITDA and Adjusted EBITDA Margin. BlueLinx defines Adjusted EBITDA as an amount equal to net income (loss) 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 our merger and acquisition activities, gains or losses on sales of properties, amortization of deferred gains on real estate, and expense associated with our restructuring activities, such as severance, in addition to other significant and/or one-time, nonrecurring, non-operating items. The Company presents Adjusted EBITDA because it is a primary measure used by management to evaluate operating performance. Management believes this metric helps to enhance investors’ overall understanding of the financial performance and cash flows of the business. Management also believes Adjusted EBITDA is helpful in highlighting operating trends. 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. We determine our Adjusted EBITDA Margin, which we sometimes refer to as our Adjusted EBITDA as a percentage of net sales, by dividing our Adjusted EBITDA for the applicable period by our net sales for the applicable period. We believe that this ratio is useful to investors because it more clearly defines the quality of earnings and operational efficiency of translating sales to profitability. Adjusted Net Income and Adjusted Earnings Per Share. BlueLinx defines Adjusted Net Income as net income 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 our merger and acquisition activities, gains or losses on sales of properties, amortization of deferred gains on real estate, and expense associated with our restructuring activities, such as severance, in addition to other significant and/or one-time, nonrecurring, non-operating items, further adjusted for the tax impacts of such reconciling items. BlueLinx defines Adjusted Earnings Per Share (basic and/or diluted) as the Adjusted Net Income for the period divided by the weighted average outstanding shares (basic and/or diluted) for the periods presented. We believe that Adjusted Net Income and Adjusted Earnings Per Share (basic and/or diluted) are useful to investors to enhance investors’ overall understanding of the financial performance of the business. Management also believes Adjusted Net Income and Adjusted Earnings Per Share (basic and/or diluted) are helpful in highlighting operating trends. Free Cash Flow. BlueLinx defines free cash flow as net cash provided by operating activities less total capital expenditures. Free cash flow is a measure used by management to assess our financial performance, and we believe it is useful for investors because it relates the operating cash flow of the Company to the capital that is spent to continue and improve business operations. In particular, free cash flow indicates the amount of cash generated after capital expenditures that can be used for, among other things, investment in our business, strengthening our balance sheet, and repayment of our debt obligations. Free cash flow does not represent the residual cash flow available for discretionary expenditures since there may be other nondiscretionary expenditures that are not deducted from the measure. Net Debt, Net Debt Excluding Real Property Finance Lease Liabilities, Overall Net Leverage Ratio, and Net Leverage Ratio Excluding Real Property Finance Lease Liabilities. BlueLinx calculates Net Debt as its total short- and long-term debt, including outstanding balances under our term loan and revolving credit facility and the total amount of its obligations under finance leases, less cash and cash equivalents. Net Debt Excluding Real Property Finance Lease Liabilities is calculated in the same manner as Net Debt, except the total amount of obligations under real estate finance leases are excluded. Although our credit agreements do not contain leverage covenants, a net leverage ratio excluding finance lease obligations for real property is included within the terms of our revolving credit agreement. We believe that Net Debt and Net Debt Excluding Real Property Finance Lease Liabilities are useful to investors because our management reviews both metrics as part of its management of overall liquidity, financial flexibility, capital structure and leverage, and creditors and credit analysts monitor our net debt as part of their assessments of our business. We determine our Overall Net Leverage Ratio by dividing our Net Debt by Twelve-Month Trailing Adjusted EBITDA. Our calculation of Net Leverage Ratio Excluding Real Property Finance Lease Liabilities is determined by dividing our Net Debt Excluding Real Property Finance Lease Liabilities by Twelve-Month Trailing Adjusted EBITDA. We believe that these ratios are useful to investors because they are indicators of our ability to meet our future financial obligations. In addition, our Net Leverage Ratio is a measure that is frequently used by investors and creditors. Our Net Debt, Net Debt Excluding Real Property Finance Lease Liabilities, Overall Net Leverage Ratio, and Net Leverage Ratio Excluding Real Property Finance Lease Liabilities are not made in accordance with GAAP and are not intended to present a superior measure of our financial condition from measures and ratios determined under GAAP. The calculations of our Net Debt, Net Debt Excluding Real Property Finance Lease Liabilities, Overall Net Leverage Ratio, and Net Leverage Ratio Excluding Real Property Finance Lease Liabilities are presented in the table on page 25. Net Debt, Net Debt Excluding Real Property Finance Lease Liabilities, Overall Net Leverage Ratio, and Net Leverage Ratio Excluding Real Property Finance Lease Liabilities, as used herein, are not necessarily comparable to other similarly titled captions of other companies due to differences in methods of calculation. 18 Non-GAAP Measures and Supplemental Financial Information
