What's Driving CSTM's Business? Latest 10-Q Breakdown

✓ 31/31 datapoints verified

AI-extracted from CONSTELLIUM SE's 10-Q filed 2026-07-29 — Q2 FY2026 (quarter ended June 30, 2026). Every figure is machine-verified against the filing text on SEC EDGAR.

Revenue rose 31% YoY to $2,748M on higher metal prices and mix, while a $129M non-cash metal price lag benefit (vs. -$19M a year ago) drove Adjusted EBITDA up to $439M from $146M.

Biggest Revenue Drivers

Packaging & Automotive Rolled Products (P&ARP)$1.68B+36% YoY

Higher revenue per ton including higher metal prices, partially offset by lower shipments (packaging down, automotive up on North American supply shortages)

Aerospace & Transportation (A&T)$680M+38% YoY

Higher shipments (+21%) and higher revenue per ton, benefiting from improved aerospace/TID market and North American automotive rolled products supply shortages

Biggest Revenue Drivers

Total revenue: $2.7B+31% YoY

Packaging & Automotive Rolled Products (P&ARP)$1.68B+36% YoY

Higher revenue per ton including higher metal prices, partially offset by lower shipments (packaging down, automotive up on North American supply shortages)

Aerospace & Transportation (A&T)$680M+38% YoY

Higher shipments (+21%) and higher revenue per ton, benefiting from improved aerospace/TID market and North American automotive rolled products supply shortages

Automotive Structures & Industry (AS&I)$458M+9% YoY

Higher revenue per ton including higher metal prices; shipments were stable

Largest Expense Items

Cost of sales (excl. D&A)$2.27B+23% YoY

28% increase in raw materials and consumables, primarily driven by higher metal prices

Selling and administrative expenses$101M+15% YoY

Higher labor costs and costs associated with corporate transformation projects

Research and development expenses$14M+17% YoY

Increase in labor costs

Margins: Cost of sales fell to 83% of revenue from 87% a year ago, helped by favorable metal costs at Muscle Shoals and Neuf Brisach and better price/mix; Adjusted EBITDA nearly tripled to $439M, though $129M of that reflects non-cash metal price lag.

Watch Items from the Filing

Adjusted EBITDA of $439M included a $129M non-cash metal price lag benefit versus a -$19M drag a year earlier, meaning underlying operating improvement is smaller than the headline suggests.
Average U.S. Midwest aluminum premium rose 154% YoY following Section 232 tariff actions, a major driver of both revenue and cost of sales increases.
P&ARP packaging rolled product shipments declined, pulling segment shipments down 4% YoY even as automotive rolled products benefited from North American supply shortages.
Board authorized a new $300 million share repurchase program (effective May 21, 2026) with $287 million still available at quarter-end after $20 million returned to shareholders in Q2.
