FOR IMMEDIATE RELEASE

VULCAN TO ACQUIRE U.S. CONCRETE

Enhances and expands Vulcan’s aggregates-led business in attractive growing metropolitan areas

Birmingham, Alabama & Euless, Texas – June 7, 2021 – Vulcan Materials Company (NYSE: VMC), a leading producer of construction aggregates, and U.S. Concrete, Inc. (NASDAQ: USCR), a leading supplier of aggregates and ready-mixed concrete, today announced that they have entered into a definitive merger agreement. Under the terms of the agreement, Vulcan will acquire all of the issued and outstanding shares of U.S. Concrete common stock for a purchase price of $74.00 per share in cash, which represents a total equity value of $1.294 billion. The transaction has been unanimously approved by the boards of directors of both companies and is expected to close in the second half of 2021, subject to U.S. Concrete shareholder approval, regulatory clearance, and other customary closing conditions.

Headquartered in Euless, Texas, U.S. Concrete operates in large, attractive metropolitan areas that complement Vulcan’s existing footprint. With 27 aggregates operations serving California, Texas and the Northeast, that shipped 12.6 million tons in 2020, the acquisition of U.S. Concrete’s portfolio represents a natural addition to Vulcan’s business. The transaction also provides strategically oriented ready-mixed concrete operations that will expand Vulcan’s service capabilities. Other highlights include:

• Complements Vulcan’s existing aggregates business in California with access to blue-water source of high quality aggregates reserves;

• Enhances Vulcan’s position in key Texas growth areas;

• Expands Vulcan’s aggregates footprint, including in the attractive New York and New Jersey metropolitan areas;

• Expected to increase Vulcan’s EBITDA by approximately $190 million before synergies; and,

• Expected to be accretive to Vulcan’s earnings per share in the first full year following closing.

Tom Hill, Chairman and CEO of Vulcan Materials Company, said, “U.S. Concrete is an important Vulcan customer in a number of key areas, and this transaction is a logical and exciting step in our growth strategy as we further bolster our geographic footprint. Ronnie Pruitt and his team have done an excellent job growing and operating its business, and we look forward to welcoming the U.S. Concrete employees to the Vulcan family. This is a merger of two corporate cultures that value people, technology, operating disciplines, customer service and the entrepreneurial spirit, and it positions Vulcan to further drive sustainable, long-term shareholder value.”

NON-GAAP MEASURES

GAAP does not define “Earnings Before Interest, Taxes, Depreciation and Amortization” (EBITDA) and it should not be considered as an alternative to earnings measures defined by GAAP. We use this metric to assess the operating performance of our business and as a basis for strategic planning and forecasting as we believe that it closely correlates to long-term shareholder value. We do not use this metric as a measure to allocate resources. We adjust EBITDA for certain items to provide a more consistent comparison of earnings performance from period to period. It is not practicable to reconcile, without unreasonable efforts, these forward looking measures to the most comparable GAAP measures due to unknown variables and uncertainty related to future results. Please see note on Forward-Looking Statement Disclaimer for further discussion.
