These forward-looking statements include, without limitation, statements concerning plans, objectives, goals, projections, outlook, strategies, future events or performance, and underlying assumptions and other statements, which are not statements of historical facts. In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “intend,” “should,” “expect,” “plan,” “target”, “anticipate,” “believe,” “estimate,” “outlook,” “predict,” “potential” or “continue,” the negative of such terms or other comparable terminology. These forward-looking statements, which are subject to risks, uncertainties and assumptions about us, may include projections of our future financial performance, our anticipated growth strategies and anticipated trends in our business. These statements are predictions based on our current expectations and projections about future events which we believe are reasonable. Actual events or results may differ materially. By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. We believe that these risks and uncertainties include, but are not limited to: general economic and business conditions, which will, among other things, affect demand for new residential and commercial construction; our ability to successfully identify, manage, and integrate acquisitions; the cyclical nature of, and changes in, the real estate and construction markets, including pricing changes by our competitors; governmental requirements and initiatives, including those related to mortgage lending, financing or deductions, funding for public or infrastructure construction, land usage, and environmental, health, and safety matters; disruptions, uncertainties or volatility in the credit markets that may limit our, our suppliers’ and our customers’ access to capital; our ability to successfully implement our operating strategy; weather conditions; our substantial indebtedness and the restrictions imposed on us by the terms of our indebtedness; the effects of currency fluctuations on our results of operations and financial condition; our ability to maintain favorable relationships with third parties who supply us with equipment and essential supplies; our ability to retain key personnel and maintain satisfactory labor relations; and product liability, property damage, results of litigation and other claims and insurance coverage issues. These risks and uncertainties also include the effects of COVID-19; the length and severity of the COVID-19 pandemic; the pace of recovery following the COVID-19 pandemic; our ability to implement cost containment strategies; and the adverse effects of COVID-19 on our business, the economy and the markets we serve. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements. Moreover, neither we nor any other person assumes responsibility for the accuracy and completeness of the forward-looking statements. All written and oral forward-looking statements made in connection with this press release that are attributable to us or persons acting on our behalf are expressly qualified in their entirety by the “Risk Factors” in our Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q filed with the Securities and Exchange Commission. We are under no duty to update any of the forward-looking statements after the date of this press release to conform such statements to actual results or to changes in our expectations, except as required by federal securities laws. There can be no assurance that other factors will not affect the accuracy of these forward-looking statements or that our actual results will not differ materially from the results anticipated in such forward-looking statements. Unpredictable or unknown factors we have not discussed in this press release also could have material effects on actual results or matters that are the subject of our forward-looking statements. We undertake no obligation to, and do not intend to, update our description of important factors each time a potential important factor arises. Non-GAAP Financial Measures. Included in this presentation are certain non-GAAP financial measures that we believe are useful for investors. These non-GAAP financial measures may not be comparable to similarly titled measures other companies report and are not intended to be used as an alternative to any measure of our performance in accordance with GAAP. Please see the appendix to this presentation reconciliations. Industry and Market Data.

These third-party sources generally include a statement that the information contained therein has been obtained from sources believed to be reliable. However, industry and market data is subject to change and cannot always be verified with certainty due to limits on the availability and reliability of raw data, the voluntary nature of the data gathering process and other limitations and uncertainties inherent in any statistical survey.

Reconciliation of Non-GAAP Financial Measures Total Adjusted EBITDA and Total Adjusted EBITDA Margin are non-GAAP financial measures. We define Total Adjusted EBITDA as our income (loss) from continuing operations, excluding the impact of income taxes, depreciation, depletion and amortization, net interest expense and certain other non-cash, non-recurring and/or unusual, non-operating items including, but not limited to: non-cash stock compensation expense, non-cash change in value of contingent consideration, impairment of assets, acquisition-related costs, officer transition expenses, purchase accounting adjustments for inventory and realignment initiative costs. Acquisition-related costs consist of fees and expenses for accountants, lawyers and other professionals incurred during the negotiation and closing of strategic acquisitions and certain acquired entities' management severance costs. Acquisition-related costs do not include fees or expenses associated with post-closing integration of strategic acquisitions. We define Total Adjusted EBITDA Margin as the amount determined by dividing Total Adjusted EBITDA by total revenue. We have included Total Adjusted EBITDA and Total Adjusted EBITDA Margin herein because they are widely used by investors for valuation and comparing our financial performance with the performance of other building material companies. We also use Total Adjusted EBITDA and Total Adjusted EBITDA Margin to monitor and compare the financial performance of our operations. Total Adjusted EBITDA does not give effect to the cash we must use to service our debt or pay our income taxes and thus does not reflect the funds actually available for capital expenditures. In addition, our presentation of Total Adjusted EBITDA may not be comparable to similarly titled measures other companies report. Total Adjusted EBITDA and Total Adjusted EBITDA Margin are not intended to be used as an alternative to any measure of our performance in accordance with GAAP. The table above reconciles Total Adjusted EBITDA to the most directly comparable GAAP financial measure, which is income (loss) from continuing operations and is presented per respective years financial statements. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, our reported operating results or cash flow from operations or any other measure of performance prepared in accordance with GAAP. 32 ($ in millions) 2011 2015 2016 2017 2018 2019 2020 Adjusted EBITDA Reconciliation Income (loss) from continuing operations ($10.2) ($5.1) $9.6 $26.2 $31.3 $16.3 $24.5 Income tax expense (benefit) (0.8) 0.8 21.2 12.4 16.8 12.3 (5.0) Interest expense (benefit), net 11.1 21.7 27.7 42.1 46.4 46.1 45.9 Loss on extinguishment of debt - - 12.0 - - - 12.4 Derivative loss (gain) (13.4) 60.0 19.9 0.8 - - - Depreciation, depletion and amortization 18.6 43.6 54.9 67.8 91.8 93.2 99.7 Non-cash change in value of contingent consideration - 0.9 5.2 7.9 - 2.8 (7.3) Impairment of assets - - - 6.2 1.3 - - Hurricane-related (gains) losses, net - - - 3.0 (0.8) (2.1) - Quarry dredge costs for specific event - - - 3.4 1.1 - - Purchase accounting adjustments for inventory - - - 1.3 0.8 - 4.9 Foreign currency losses resulting from Polaris acquisition - - - 1.9 - - - Non-cash stock compensation expense 2.1 5.8 7.1 8.3 10.4 19.1 11.6 Acquisition-related costs, net - 3.8 2.2 10.1 6.2 0.1 2.8 Realignment initiative costs - - - - - - 1.7 Officer transition expenses 0.3 0.4 - 0.8 - 0.6 0.2 Loss on mixer truck fire - - - - - 0.7 - Litigation settlement costs - - - - 2.1 0.3 - Eminent domain matter - - - - 0.7 (5.3) - Gain on sale of business - - - - (14.6) - - Pension withdrawal l iability - - - - - - 1.5 Adjusted EBITDA $7.7 $131.9 $159.8 $192.2 $193.5 $184.1 $192.9 Adjusted EBITDA margin 1.7% 13.5% 13.7% 14.4% 12.8% 12.5% 14.1% Year ended December 31,
