For Immediate Release

Builders FirstSource Provides Update Related to COVID-19

April 6, 2020 (Dallas, TX) – Builders FirstSource, Inc. (Nasdaq:  BLDR) remains focused on prioritizing the safety and well-being of our team members, customers and communities as we continue to supply our essential products and services amid the global COVID-19 pandemic.

Operating with a Safety-First Approach

Builders FirstSource locations remain open and operational except in the few states or counties where construction activities have been prohibited. As an essential supplier of diversified products and services to builders and contractors, we have strictly adhered to the recommendations and guidelines promoted by the Centers for Disease Control and Prevention (CDC) and local community health departments where we operate.

In recent months, we have proactively implemented business continuity measures across our network and believe we are well prepared to manage our business through this crisis. That begins with our commitment to supporting customers while protecting the health and welfare of all team members, channel partners and the communities where we operate. General safeguards, amongst many, include enhanced location cleaning processes, remote working accommodations, suspended group activities, air travel restrictions, and promoting social distancing practices. We are also using technology where possible to facilitate customer orders and other interactions to further reduce direct contact between employees. A dedicated team of executives is in place to monitor daily best practices, ensure safety and implement swift action as needed.  

Enhancing Financial Flexibility

Builders FirstSource entered the pandemic situation with a solid capital position and balance sheet to continue operations during this volatile period. We have also taken proactive steps to further enhance our financial flexibility, liquidity and cash flow, including:

Following the draw downs in March, we had approximately $150 million of cash on hand with no debt maturities until 2024. We believe our current cash balance plus access to an estimated $480 million of

additional availability under our revolver provides the financial flexibility to manage our business with a safety-first emphasis across our nationwide footprint.

Affirms First Quarter 2020 Guidance and Withdraws Full Year 2020 Outlook

We are affirming our guidance for the first quarter ended March 31, 2020. We experienced strong activity levels through most of the quarter. Net sales for the first quarter are expected to be up between 6 to 10 percent, on a sales per day basis, compared to the prior year period. Adjusted EBITDA for the quarter is expected to be between $90 million and $100 million.

Due to the evolving macro-economic uncertainty in the current homebuilding environment, we are withdrawing our previous full year 2020 outlook, which did not contemplate the impacts of COVID-19. Management will provide a business update as part of its first quarter 2020 earnings results.

Management Comment

CEO Chad Crow remarked, “We are well prepared to navigate through this rapidly evolving pandemic. As an essential business, we are proud to continue supporting our customers with a paramount focus on health and safety. We will continue to take prudent and proactive actions to safely operate our business and maintain a strong liquidity position during this uncertain period while positioning our Company to succeed when macroeconomic conditions improve. I thank the Builders FirstSource team for their unwavering dedication to our company, customers, and communities during this volatile time.”
