Builders FirstSource Announces Definitive Agreement to Acquire Alliance Portfolio of Businesses

Builders FirstSource, Inc. (“Builders FirstSource” or the “Company”), the nation’s premier supplier of building materials and services, today announced it has entered into a definitive agreement to acquire Cornerstone Building Alliance SW, LLC (“Alliance”), for approximately $400 million, subject to certain closing adjustments.

Alliance is the largest independently operated supplier of building materials in Arizona, primarily serving the greater Phoenix, Tucson, and Prescott Valley metropolitan areas. As a leading regional supplier with strategically located facilities, Alliance is uniquely positioned to offer unmatched distribution throughout the highest-growth regions of Arizona with a comprehensive portfolio of premium building materials. Alliance has deep, long standing customer relationships and a reputation for offering value-add services that have established it as a trusted advisor for leading contractors across single-family, multi-family, and commercial end markets. Its geographic footprint, value-added product mix, and market leadership create a highly strategic fit for Builders FirstSource’s integrated network.

Dave Flitman, President and CEO of Builders FirstSource, stated, “This acquisition is aligned with our strategy of investing organically and through M&A, to shift our portfolio toward high-value and faster-growth categories. Alliance’s service area represents the third largest single-family market and includes the fastest growing county, Maricopa, in the country. Alliance’s geographic footprint represents an excellent strategic fit, with a limited overlap of our existing geographic coverage that enables us to expand our product lines across various end markets. Building upon the success of the BMC merger, we will be opportunistic in pursuing value-enhancing investments, such as Alliance, that align with our culture, value-added product focus, and high return thresholds. True Carr has built a fantastic company with a very strong leadership team and a culture of growth and outstanding customer service that aligns well with the Builders FirstSource culture. We are excited to welcome the over 300 hundred Alliance team members to the Builders FirstSource family.”

True Carr, Managing Partner of Alliance, will continue with Builders FirstSource. Mr. Carr stated, “This transaction provides incredible opportunities for our customers and employees. We have grown this business into an industry leader and joining the Builders FirstSource family is a clear win for all stakeholders, representing the next chapter in Alliance’s successful journey. We are thrilled to continue to provide exceptional products and services to our customers as part of Builders FirstSource. The future of Alliance is very bright.”

Alliance reported TTM sales of approximately $330 million as of April 2021. The acquisition is expected to be accretive to the Company’s adjusted earnings per share in 2021 and will be funded through a combination of existing cash and credit facilities. It is expected to close around the end of the second quarter of 2021, subject to customary closing conditions and approvals.

Alliance was advised by Anchor Peabody in the transaction.
