Rhea AI BLD FY2025

TopBuild still turns sales into cash, but FY2025 reveals weaker margins and a more debt-funded balance sheet.

By FY2025, revenue reached $5.4B while operating margin was 14.6%, lower than FY2023. The combination points to modest top-line expansion accompanied by less profit per sales dollar, rather than stronger operating leverage.

Asset expansion took total assets from $5.2B in FY2023 to $6.6B in FY2025, indicating a materially larger balance-sheet footprint. Long-term debt reached $2.8B and debt-to-equity rose to 1.2x, showing greater reliance on debt financing.

FY2025 operating cash flow was $756M versus free cash flow of $697M, so reported earnings were largely converted into cash after capital spending. However, net income fell to $522M as gross margin slipped to 29.0%, linking the earnings decline to weaker gross profitability rather than a cash shortfall.
