EULESS, TEXAS – May 8, 2014 – U.S. Concrete, Inc. (NASDAQ: USCR) today reported adjusted EBITDA of $9.5 million in the first quarter of 2014, compared to $4.0 million in the first quarter of 2013. Adjusted EBITDA margin, which is adjusted EBITDA as a percentage of revenue, was 6.5% for the first quarter of 2014, compared to 3.2%in the first quarter of 2013. Net loss was $1.2 million, or ($0.09) per diluted share, for the first quarter of 2014, compared to a net loss of $14.4 million, or ($1.16) per diluted share, in the first quarter of 2013.

William J. Sandbrook, President and Chief Executive Officer of U.S. Concrete, stated “Our first quarter results continue to reflect the positive momentum we have generated over the last two years. We are extremely pleased with our ability to capitalize on the growth in the overall construction market, expand our presence in our key markets and show continued growth in volumes, pricing and profitability in both of our business segments. Our outlook for the business continues to be strong and we are very excited about the Company's prospects for this year. The construction environment in Texas and California continues to be robust and our decisions to expand ready-mixed concrete capacity in both of those markets and sand and gravel capacity in Texas are now paying great dividends."

FIRST QUARTER2014 RESULTS (all comparisons, unless noted, are with the prior year quarter)

Consolidated revenue increased 16.6% to $146.3 million, compared to $125.4 million in the prior year. Revenue from the ready-mixed concrete segment increased $18.7 million, or 16.3%, driven by both volume and pricing. The Company’s

ready-mixed concrete sales volume was 1.3 million cubic yards, up 10.7% over prior year. Ready-mixed concrete average sales price per cubic yard increased $5.13, or 5.1%, to $106.53 compared to $101.40 in the prior year. Aggregate products segment revenue increased $1.7 million, or 26.5%, to $8.2 million on increased sales volume of 112 thousand tons, an improvement of 16.1% over prior year.

Consolidated gross profit increased $4.9 million with a 144 basis point expansion in margin year-over-year. Consolidated adjusted EBITDA of $9.5 million, increased $5.5 million with a 331 basis point expansion in margin year-over-year.

Selling, general and administrative expenses (“SG&A”) were $13.6 million compared to $14.3 million in the prior year. As a percentage of total revenue, SG&A expenses decreased to 9.3%, compared to 11.4% in the prior year.

During the first quarter of 2014, the Company recorded a $0.6 million non-cash loss related to derivatives. This non-cash loss was comprised of fair value changes in the Company's warrants. This compared to a non-cash loss of $18.4 million during the first quarter of 2013 from fair value changes in the Company's warrants and convertible notes. These changes were due to the increase in the price of the Company's stock during the first quarters of 2014 and 2013.

The Company’s free cash flow in the first quarter of 2014 was ($9.8) million, compared to ($9.1) million in the prior year. The decrease in free cash flow was due to increased capital expenditures which increased $8.3 million over prior year. The increase in capital expenditures was due to higher spending on mixer trucks, ready-mixed plant capacity expansions in California, a new aggregates plant in New Jersey and the development of our new Red River sand and gravel operation on the border of Texas and Oklahoma, all to support the growing demand in our markets.

The Company’s net debt at March 31, 2014 was $118.3 million, up $16.8 million from December 31, 2013. The increase in net debt was due to a reduction in cash and cash equivalents during the first quarter of 2014, primarily due to increased capital expenditures and the acquisition of two ready-mixed concrete plants in west Texas. Net debt at March 31, 2014 was comprised of total debt of $214.5 million, less cash and cash equivalents of $96.2 million.

Ready-mix backlog at the end of the first quarter of 2014 was approximately 4.3 million cubic yards, up 23.4% compared to the end of the first quarter of 2013 and up 7.8% since the beginning of the year.

USE OF NON-GAAP FINANCIAL MEASURES

This press release uses the non-GAAP financial measures “adjusted EBITDA,” “adjusted net income (loss),” “adjusted EBITDA margin,” “free cash flow” and “net debt.” The Company has included adjusted EBITDA and adjusted EBITDA

2

margin in this press release because it is widely used by investors for valuation and comparing the Company’s financial performance with the performance of other building material companies. The Company also uses adjusted EBITDA and adjusted EBITDA margin to monitor and compare the financial performance of its operations. Adjusted EBITDA does not give effect to the cash the Company must use to service its debt or pay its income taxes, and thus does not reflect the funds actually available for capital expenditures. In addition, the Company’s presentation of adjusted EBITDA and adjusted EBITDA margin may not be comparable to similarly titled measures that other companies report. The Company considers free cash flow to be an important indicator of its ability to service debt and generate cash for acquisitions and other strategic investments. The Company believes that net debt is useful to investors as a measure of its financial position. The Company presents adjusted net income (loss) and adjusted net income (loss) per share to provide more consistent information for investors to use when comparing operating results for the first quarter of 2014 to the first quarter of 2013. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s reported operating results or cash flow from operations or any other measure of performance as determined in accordance with GAAP. See the attached “Additional Statistics” for reconciliation of each of these non-GAAP financial measures to the most comparable GAAP financial measures for the quarters ended March 31, 2014 and 2013.

ADDITIONAL STATISTICS

(Unaudited)

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 below for (1) presentations of our adjusted EBITDA, adjusted EBITDA margin and Free Cash Flow for the quarters ended March 31, 2014 and 2013, and Net Debt as of March 31, 2014 and December 31, 2013 and (2) corresponding reconciliations to GAAP financial measures for the quarters ended March 31, 2014 and 2013 and as of March 31, 2014 and December 31, 2013. We have also provided below (1) the impact of non-cash stock compensation expense, derivative losses, gain (loss) on extinguishment of debt, officer severance and expenses related to the Company’s relocation of the corporate headquarters on net income (loss) and net income (loss) per share and (2) corresponding reconciliations to GAAP financial measures for the quarters ended March 31, 2014 and 2013. We have also shown below certain Ready-Mixed Concrete Statistics for the quarters ended March 31, 2014 and 2013.

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 loss, gain (loss) on extinguishment of debt, officer severance and expense related to the Company’s relocation of the corporate headquarters. We define adjusted EBITDA margin as the amount determined by dividing adjusted EBITDA by total revenue. We have included adjusted EBITDA and adjusted EBITDA margin in the accompanying tables 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.

We define adjusted net income (loss) and adjusted net income (loss) per share as net income (loss) and net income (loss) per share excluding non-cash stock compensation expense, derivative loss, gain (loss) on extinguishment of debt, officer severance and expense related to the Company’s relocation of the corporate headquarters. We present adjusted net income (loss) and adjusted net income (loss) per share to provide more consistent information for investors to use when comparing operating results for the quarters ended March 31, 2014 and 2013.

We define Free Cash Flow as cash provided by (used in) operations less capital expenditures for property, plant and equipment, net of disposals. We consider Free Cash Flow to be an important indicator of our ability to service our debt and generate cash for acquisitions and other strategic investments.

We define Net Debt as total debt, including current maturities and capital lease obligations, minus cash and cash equivalents. We believe that Net Debt is useful to investors as a measure of our financial position.

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.
