On March 21, 2017, the Audit Committee (the “Audit Committee”) of the Board of Directors of U.S. Concrete, Inc., a Delaware corporation (the “Company”), in consultation with the Company’s Board of Directors, approved the engagement of Ernst & Young LLP (“Ernst & Young”) as the Company’s new independent registered public accounting firm, effective March 22, 2017.

The Company’s current independent registered public accounting firm, Grant Thornton LLP (“Grant Thornton”), was notified on March 22, 2017 of its immediate dismissal.

The reports of Grant Thornton on the Company’s consolidated financial statements for the fiscal years ended December 31, 2016 and 2015 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

During the fiscal years ended December 31, 2016 and 2015 and the subsequent interim period through March 22, 2017, there have been no “disagreements” (as defined in Item 304(a)(1)(iv) of Regulation S-K and related instructions) with Grant Thornton on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Grant Thornton, would have caused Grant Thornton to make reference thereto in their reports on the consolidated financial statements for such fiscal years. During the fiscal years ended December 31, 2016 and 2015 and any subsequent interim period through March 22, 2017, there have been no “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K), except that the Company’s internal control over financial reporting was not effective due to the existence of material weaknesses in the Company’s internal control over financial reporting. As disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016, a material weakness relating to management review controls associated with the completeness and accuracy of computations relating to income tax accounts and disclosures was identified. As disclosed in the Company’s Amendment No. 1 on Form 10-K/A, which amended the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015, a material weakness relating to the accuracy and presentation of the accounting for income taxes, including the income tax provision and related tax assets and liabilities was identified.

Grant Thornton discussed each of these matters with the Audit Committee. The Company has authorized Grant Thornton to fully respond to the inquiries of Ernst & Young, the successor independent registered public accounting firm, concerning these matters.

The Company provided Grant Thornton with a copy of the disclosure it is making herein in response to Item 304(a) of Regulation S-K and requested that Grant Thornton furnish the Company with a copy of its letter addressed to the SEC, pursuant to Item 304(a)(3) of Regulation S-K, stating whether or not Grant Thornton agrees with the statements related to them made by the Company in this report. A copy of Grant Thornton’s letter to the SEC dated March 24, 2017, is attached as Exhibit 16.1 to this report.

During the fiscal years ended December 31, 2016 and 2015 and any subsequent interim period through March 22, 2017, neither the Company, nor anyone on its behalf, consulted Ernst & Young regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the financial statements of the Company, and no written report or oral advice was provided to the Company by Ernst & Young that Ernst & Young concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a “disagreement” (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a “reportable event” (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).

Resignation of Chief Financial Officer, Principal Financial Officer and Principal Accounting Officer

On March 24, 2017, the Company announced that Joseph C. “Jody” Tusa, Jr., the Company’s Senior Vice President and Chief Financial Officer, has resigned from his positions with the Company for personal reasons, effective as of July 1, 2017 (the “Separation Date”). Mr. Tusa’s role as principal accounting officer will cease on April 1, 2017. Mr. Tusa’s anticipated departure is not as a result of any disagreement with the Company.

In connection with the foregoing, on March 23, 2017, the Company and Mr. Tusa entered into a Separation and Transition Agreement (the “Agreement”). The Agreement provides that Mr. Tusa will remain employed with the Company and provide transition services, as requested by the Chief Executive Officer of the Company, until the Separation Date. In exchange for providing transition services, and subject to Mr. Tusa’s compliance with the terms of the Agreement, Mr. Tusa will receive the following payments and benefits from the Company:

In consideration of the payments and benefits due to Mr. Tusa under the Agreement, Mr. Tusa agrees to execute a general release of claims in favor of the Company and further agrees not to compete with the Company or solicit the Company’s customers or employees for a period of one year following the Separation Date.

The foregoing description of the Agreement does not purport to be complete and is qualified in its entirety by reference to the Agreement attached hereto as Exhibit 10.1.
