TopBuild to Acquire USI in

All-Cash Transaction Valued at $475 Million

USI is a Leading Provider of Insulation Installation and Distribution Services to the Residential and Commercial Construction Markets

Conference Call Scheduled for 8:00 a.m. ET Today

DAYTONA BEACH, FL – March 2, 2018 — TopBuild Corp. (NYSE:BLD) has entered into  an  agreement to acquire United Subcontractors, Inc. (“USI”) in an all-cash transaction valued at $475 million. The Company expects to finance the acquisition using a combination of debt financing and cash on hand.

USI is a leading provider of insulation installation and distribution services to the residential and commercial construction markets, generating pro forma annual revenue of approximately $375 million in 2017 and an adjusted EBITDA margin of 12.5%.   It has a diversified product and service offering including fiberglass, spray foam and window and glass installation.  Founded in 1998 and headquartered in St. Paul, Minnesota, USI has 38 locations in 14 states, including high growth regions in the Pacific Northwest, Mountain West, Southwest and Southeast.

TopBuild expects to achieve cost savings of $15 million, with approximately $5 million to $10 million expected in the first full year after closing and the full run-rate by the end of year two after closing.  The acquisition provides TopBuild with a stronger geographic footprint in key growth regions and a more robust business and product mix,  which should enhance the value proposition for customers.

Jerry Volas, Chief Executive Officer of TopBuild, stated, “Since implementing our acquisition program in August 2016, we have completed nine transactions and have established a successful track record of integrating them onto our systems and supply chain.  We’ve also closely adhered to our strategy of seeking well managed companies with experienced operators, well-trained installers, solid customer bases and a footprint that expands our presence in high growth geographies.  USI fits well within these stated goals.”

Bill Varner, Chief Executive Officer of USI, noted, “We are very pleased to announce this transaction with TopBuild.  This will be a tremendous outcome for all our stakeholders as the combined organization will be better positioned to provide innovative and high-quality solutions to our customers.  Both companies have shared values and are guided by a commitment to reliability, high performance and safety.”

On a December 31, 2017 pro forma basis, inclusive of expected run rate synergies of $15 million, the combined company had revenue of $2.3 billion, adjusted EBITDA of $259 million, almost 10,000 employees and close to 300 installation and distribution locations.

The Company plans to fund this transaction using proceeds from a $350 million bond issuance,  $100 million from a delayed draw term loan commitment currently available under its existing secured credit facility and $25 million from cash on hand or drawings under its revolving credit facility.  In the event the bond market terms are not attractive to the Company at the time of execution, the Company would expect to finance the transaction with secured bank debt.

At the close of the transaction, the Company’s net debt to pro  forma adjusted EBITDA implies a multiple of 2.9 times pre-synergies, or 2.8 times post-synergies.

Volas noted, “The transaction is expected to be accretive in the first year and it should produce strong cash flow, enabling us to de-lever quickly.  We expect to benefit from greater supply chain efficiencies, a strong and energized branch management team, and the addition of a seasoned labor force.  Bottom line, we are confident it will help drive value creation for our shareholders.”

The transaction, which has been approved by TopBuild’s Board of Directors, is subject to customary closing conditions, including expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.  The Company expects the transaction to close in the second quarter of 2018.
