Builders FirstSource announced its third‑quarter 2026 results, posting adjusted earnings of $1.51 per share that topped the $1.04 consensus. Revenue was reported around $3.85‑$3.9 billion, a modest year‑over‑year decline, while the company reaffirmed its full‑year net‑sales outlook of $14.2‑$14.6 billion and lifted its adjusted EBITDA target to about $1.1 billion. Management highlighted 1‑2 percentage‑point market‑share gains, cost‑saving initiatives and two acquisitions that expanded its Southeast footprint.
