12 Experienced Management Team Driving Sustainable Business Improvement Executive leadership focused on positioning the business for continued success  Demonstrated commitment to focus on highly attractive geographies and end markets with superior margin projects  Dallas, New York and San Francisco are among the strongest non-residential and residential construction markets  Commercial construction orientation requires greater technical expertise and product capabilities  Synergistic acquisitions within existing footprint or in geographies with defensible market positions  Margin results supported by achieved shift in concrete pricing and material margin spread  USCR’s average price per cubic yard was ~$25 greater than industry average in 2016 compared to average price in- line with industry in 2009  Resulting material margin spread has increased from $43/cubic yard in 2009 to $66/cubic yard LTM 6/30/17  Material spread margin in prior downturn (2007 to 2009) increased from $40/cubic yard to $43/cubic yard  Greater vertical integration of aggregates business has also enhanced Adjusted EBITDA margins  Internal requirements are ~1/3 filled from USCR quarries in markets with aggregates positions  External aggregates sales for 2016 are approximately $19.8mm higher than 2009  Sales of aggregates achieve Adjusted EBITDA margins greater than 20% ($mm) 2007 2009 2016 LTM 6/30/2017 Commentary Revenue $803.8 $534.5 $1,168.2 $1,287.4  Greater scale Adjusted EBITDA2 $75.4 $17.4 $159.8 $194.1  Higher profitability Adjusted EBITDA margin2 9.4% 3.2% 13.7% 15.1%  Improved EBITDA margins Material spread margin ($ / cubic yard) ~$40 ~$43 ~$64 ~$66  Stable spreads during downturn, and better material spread margins today Ready-mixed sales volume (mm cubic yards) ~7.6 ~3.9 ~8.1 ~8.8  Steady volume, now with differentiated composition Leverage1 4.0x 17.0x 2.34x 2.07x  Lower leverage 1 Defined as net debt / Adjusted EBITDA 2 2007 and 2009 reflect total consolidated results; LTM 6/30/17 reflects results from continuing operations

14 Vertical Integration Into Aggregates Enhances the Value Chain  Aggregates primary focus is supply of U.S. Concrete’s ready-mixed concrete operations  Aggregates exposure generates higher overall corporate margins  Vertical integration enhances market dynamics  Provides stable supply and strategic advantage  Improves overall purchasing power  Increases precision in bidding for new projects Aggregates used in USCR’s ready-mixed concrete operations1, LTM 6/30/17 Externally sourced & acquisition opportunities 69% Internally sourced 31%  Key focus of acquisition strategy  17 aggregates producing facilities, one recycling operation, four distribution terminals  ~160 million tons of owned and leased reserves USCR Becomes More Vertically Integrated ¹ From regions where USCR has aggregates

15 Significant Industry Consolidation Opportunities Exist to Enable Scaling of USCR’s Ready-Mixed Business Ready-Mixed Concrete Market Size for U.S. (as of December 2016) Deal opportunities remain robust  USCR is an acquirer of choice in established markets through decades long relationships amongst local and national management teams  Aggregates provide additional expansion opportunities and strengthen vertically integrated capabilities  Increasing vertical integration among cement, aggregates and concrete producers represents favorable market dynamic Annual Revenue $30.0 B Ready-Mixed Concrete Producers 2,200 Ready-Mixed Concrete Plants 6,500 Source: NRMCA; IBISWorld

16 Focused and Disciplined Acquisition Strategy Continue to expand within existing regional markets through ready-mixed concrete bolt-ons and vertical integration into aggregates Local Opportunity Expand concentrically around existing regions Regional Opportunity Selected larger-scale opportunities in new geographies  Strong, stable markets with promising growth profiles  Appealing market structures  Defensible positions of scale with barriers to entry National Opportunity Successful Deal Track Record with Significant Consolidation Pipeline

42 Reconciliation of Non-GAAP Financial Measures We report our financial results in accordance with generally accepted accounting principles in the United States (“GAAP”). However, our management believes that certain non-GAAP performance measures and ratios, which our management uses in managing our business, may provide users of this financial information additional meaningful comparisons between current results and results in prior operating periods. See the table above for presentations of our Adjusted EBITDA and Adjusted EBITDA Margin for the last twelve months ending June 30, 2017 and the years ending December 31, 2016, 2015, 2014, 2013, 2012, 2011, 2009 and 2007. We define Adjusted EBITDA as our net income (loss) from continuing operations, plus the provision (benefit) for income taxes, net interest expense, depreciation, depletion and amortization, non-cash stock compensation expense, derivative (gain) loss, (gain) loss on extinguishment of debt, non-cash gain (loss) on revaluation of contingent consideration, officer severance, acquisition-related professional fees, expense related to the departure of our former Chief Executive Officer, expense related to our corporate headquarters relocation, and reorganization items. We have included Adjusted EBITDA and 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 Adjusted EBITDA and Adjusted EBITDA Margin to monitor and compare the financial performance of our operations. 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 Adjusted EBITDA may not be comparable to similarly titled measures other companies report. Adjusted EBITDA and Adjusted EBITDA Margin are not intended to be used as an alternative to any measure of our performance in accordance with GAAP. 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. The Company applied the Financial Accounting Standards Board’s Accounting Standards Codification (“ASC”) 852 “Reorganizations” to its financial statements while the Company operated under the provisions of Chapter 11 of the United States Bankruptcy Code. As of August 31, 2010, the Company applied fresh-start accounting under the provisions of ASC 852. The adoption of fresh-start accounting resulted in the Company becoming a new entity for financial reporting purposes. Accordingly, the Company’s financial statements for periods prior to August 31, 2010 are not comparable with its financial statements for periods on or after August 31, 2010. References to “Successor” in the Company’s financial statements refer to the Company on or after August 31, 2010, after giving effect to the provisions of our Plan of Reorganization and the application of fresh-start accounting. References to “Predecessor” in the Company’s financial statements refer to the Company prior to August 31, 2010. Because of various adjustments to the Company’s consolidated financial statements in connection with the application of fresh-start accounting, including asset valuation adjustments and cancellation of debt adjustments, the results of operations for the Successor are not comparable to those of the Predecessor.
