AI Analysis

AI-generated, general educational analysis — not personal investment advice.

Mueller Industries is a metal fabricator with three segments - Piping Systems, Industrial Metals, and Climate - selling copper, brass, and aluminum products. I look first at business quality. FairStock calculations show return on equity of 26.32% and return on capital employed of 16.49%, while the provided debt-to-equity is 0.01 and Altman Z-Score is 14.53. That is a strong balance sheet. Filed results show progress: FY2023 revenue was $3.4B, net income $602.9M, diluted EPS $5.30; FY2024 revenue was $3.8B, net income $604.9M, diluted EPS $5.31; FY2025 revenue was $4.2B, net income $765.2M, diluted EPS $6.86. In fiscal Q2 2026, the quarter ended 2026-06-27, revenue was $1.4B, net income $249.7M, and margin 17.48%. Cash generation is real: trailing free cash flow was $666.4M, and FairStock calculates an FCF yield of 4.9%. But valuation matters. At the 2026-10-13 close of $61.51, FairStock calculates P/E 16.02, P/B 3.83, PEG 10.54, Graham Number $37.24, and margin of safety -65.17%. The price is well above that Graham-style value. FairStock's Lynch category is FAST GROWER, citing 40.6% annual profit growth over five years and 11.7% revenue growth, yet the provided profit growth of 1.52% and Piotroski F-Score of 4/9 suggest momentum has cooled. I see a high-quality industrial with a fortress balance sheet, but not a bargain by conservative measures.

In plain English: Mueller Industries makes copper, brass, and aluminum products for plumbing, industrial, and climate uses. The business looks financially strong, with solid profits, very little debt, and good cash flow, but profit growth has slowed recently. At the 2026-10-13 close, the price looks expensive compared with its accounting value, so it does not look like a bargain on that measure.
