**Third Quarter Performance**: Builders FirstSource (BFS) reported net sales of $4.2 billion, a decline of 6.7% year-over-year due to a 7.2% decrease in core organic sales and 2.9% commodity deflation. However, the company maintained strong gross margins of approximately 32.8%, underscoring its resilient business model.

**2024 Guidance**: For 2024, BFS narrowed its net sales guidance to $16.25 billion to $16.55 billion and adjusted EBITDA to $2.25 billion to $2.35 billion, reflecting a forecasted gross margin range of 32% to 33%. This guidance assumes normalized single-family starts of 1 million to 1.1 million, but underlying conditions show potential market challenges.

**Market Challenges**: The company faced significant headwinds, particularly in the multifamily segment, which saw a 31% decline due to affordability issues and lapping strong prior-year comparisons. Building activity remains mixed, with builders undertaking measures to manage costs and improve affordability.
