Volume Declines Across Most End Markets
In 2025, Kaiser Aluminum faced weaker shipment volumes, offset by higher aluminum prices. The US producer of semi-fabricated specialty aluminum products saw softer volumes across most segments. However, strong pricing helped drive better financial results.
In Q4 2025, shipments reached 274 million pounds (124,284 tonnes), down 6% from 292 million pounds (132,449 tonnes) in Q4 2024. On a full-year basis, shipments fell 5% to 1,108 million pounds (502,580 tonnes).
Quarterly Shipment Trends
Each 2025 quarter showed a year-over-year decline in volumes, reflecting continued demand softness. Q1 shipments were 276 million pounds, 5% lower than 2024. Q2 rose sequentially to 288 million pounds but stayed 3% below last year. Q3 fell to 270 million pounds, down both sequentially and year-over-year. Q4 rebounded 1% from Q3, aided by a planned outage ramp-up at Trentwood and stronger coated packaging volumes at Warrick.

Revenue and Earnings Supported by Pricing

CEO Keith A. Harvey said: “Our Q4 performance reflected consistent execution, marking five consecutive quarters ahead of internal expectations. Metal pricing remained favorable. Despite non-recurring costs from our new roll coat line and Phase VII outage, we delivered record full-year adjusted EBITDA of USD 310 million with a margin above 21%. We enter 2026 with solid foundations, visibility into end markets, and the capacity to capture benefits from recent investments. We remain focused on cost reductions, deleveraging, and delivering value to customers and shareholders.”
