[BLDR] Builders FirstSource Thesis 2026: Manufactured Components Defend Margins as Housing Recovery Awaits
Builders FirstSource delivered FY2025 revenue of ~$16.0B (-7%) as housing starts remained below normalized levels, but Adj. EBITDA margin held at ~15.6% supported by manufactured products mix (~35% of revenue). FCF ~$1.6B funded aggressive buybacks reducing diluted shares to ~118M (-37% since FY2021). FY2026 thesis: housing starts recovering toward 1.1-1.2M units drives revenue back toward $18-19B with expanded manufactured component margins — a combination that could restore EPS toward $10-12 and justify re-rating from trough multiples.
