Earnings Call Summary

Sales fell 10 percent to $3.3 billion as single-family starts dropped 11 percent and builders reduced home size and complexity by another 10 percent versus 2019. Gross margin fell 220 basis points to 28.3 percent, hurt by lower volume, specialty product weakness, and fuel inflation costs totaling roughly $100 million for the year. The company raised its share buyback authorization to $500 million and cut $100 million in annual costs, but remains confident in long-term market share gains as competitors struggle with tighter margins.

Guidance Builders FirstSource now expects about $14.6 billion to $15.6 billion in sales for 2026, down from prior expectations. They forecast adjusted EBITDA of $1.1 billion to $1.5 billion with margins between 7.5 and 9.6 percent. For the second quarter, they guide sales of $3.75 billion to $4.05 billion and EBITDA of $300 million to $350 million. The company cited weak housing starts, lower home values, and fuel cost inflation as reasons for the reduction.

Severe negative reset. The report materially damaged the forward outlook and likely forces major downward revisions.
