AI-extracted from the 10-Q filed 2026-10-21 — Q3 FY2026 (quarter ended September 26, 2026). Every figure is machine-verified against the filing text on SEC EDGAR.
Mueller Industries Q3 revenue surged 31.6% YoY to $1.42B, driven by higher copper and brass prices plus the Bison acquisition, though gross margins compressed 600 bps as raw material cost pass-through lagged.
Biggest Revenue Drivers
Piping Systems$890.6M+24.0% YoY
Higher net selling prices of copper tube (+$122.2M) and Bison acquisition contribution (+$52.2M), partly offset by lower unit sales volume
Industrial Metals$409.4M+64.4% YoY
Higher unit sales volume in brass rod and wire/cable (+$90.0M) and higher net selling prices (+$76.5M), partially offset by Sherwood sale (-$9.8M)

Largest Expense Items
Selling, general, and administrative expense$63.0M+2.3% YoY

Watch Items from the Filing
Gross margin compression of 600 bps YoY to 25.5% reflects lag in passing through raw material cost increases, creating near-term profitability headwind despite strong top-line growth.
Bison acquisition contributed $52.2M Q3 revenue and $139.6M integration cost, with preliminary purchase accounting still subject to measurement period adjustments through March 2027.
Environmental remediation obligations include $13.7M–$14.8M Shasta sites costs over 30 years, $1.9M–$2.0M Lead Refinery over 11 years, plus uncertain Lead Refinery NPL liability and Bonita Peak Mining District exposure with no quantified reserve.
Cash position of $1.45B and $72.6M available credit provide strong liquidity; $278.3M share repurchases and $113.9M dividends YTD reduce retained capital despite 31.6% revenue growth.
