The most recent and critical transformation involves major capital investments to capture high-growth end markets, which is why we're seeing the 2025 numbers look so strong.

• Post-Bankruptcy Focus: Emerging from bankruptcy in 2006 was a hard reset. It forced the company to shed its primary aluminum operations and focus on the higher-margin, more defensible fabricated products for aerospace and high-strength applications. That was a smart, necessary move.
• The Packaging Re-Entry: The 2021 acquisition of the Warrick rolling mill was a game-changer, bringing the company back into the packaging market. This provided immediate scale and a critical counter-cyclical revenue stream to balance the cyclical aerospace business.
• 2025 Growth Investments: The company is currently executing on significant strategic growth investments. In the first half of 2025 alone, Kaiser Aluminum allocated $82 million toward capital projects. This includes commissioning a new roll coat line at the Warrick facility and completing the Phase VII expansion at the Trentwood rolling mill in the second half of 2025.
• Financial Performance in 2025: The results are showing this strategy is working. For the third quarter of 2025, Net Sales reached $844 million, and Adjusted EBITDA was $81 million. The company's Net Debt Leverage Ratio improved to 3.6x as of September 30, 2025. They are raising their full-year 2025 Adjusted EBITDA outlook, expecting an improvement of 20% to 25% year-over-year.

Here's the quick math: The company incurred approximately $20 million in non-recurring startup costs at Trentwood and Warrick in Q3 2025, but still delivered strong adjusted earnings, showing the underlying business strength is overcoming near-term investment costs. That's a sign of a successful strategic execution.

• Product Specialization: The company's diverse range of high-quality, semi-fabricated products reduces reliance on any single market, which is a significant strength.
• Financial Deleveraging: The net debt leverage ratio improved to 3.6x as of September 30, 2025, a solid drop from 4.3x at the end of 2024.

• Strong Momentum: Based on year-to-date performance, Kaiser Aluminum raised its full-year 2025 Adjusted EBITDA outlook, expecting growth of 20% to 25% year-over-year.

Kaiser Aluminum Corporation (KALU) How It Makes Money

Kaiser Aluminum Corporation makes money primarily by transforming raw aluminum ingot into highly-engineered, semi-fabricated specialty products-like sheet, plate, and extrusions-and selling the 'conversion' service for a fee, which is the core of their profitability.

The company's revenue model is structured to pass through the cost of the underlying raw aluminum metal to the customer, meaning their profit is largely driven by the premium they charge for the value-added manufacturing process, which they call Conversion Revenue (Net Sales minus the Hedged Cost of Alloyed Metal). This insulates them somewhat from the volatile commodity price of aluminum itself.

Kaiser Aluminum Corporation's Revenue Breakdown

For the third quarter of 2025, Kaiser Aluminum reported total Net Sales of $844 million. The breakdown below shows the percentage contribution from their key end markets, illustrating the business's reliance on the packaging sector and the high-value specialty products for aerospace.

Business Economics

The financial engine of Kaiser Aluminum is built on two distinct revenue components: the pass-through metal cost and the conversion premium. The conversion premium is where the real margin is made, and it's why the company tracks Conversion Revenue so closely.

Here's the quick math: when you look at the Q3 2025 Net Sales of $844 million, the Conversion Revenue was only $351 million. The difference-over $490 million-is the cost of the raw metal, which they largely hedge and pass directly to the customer. This structure means their profitability is less exposed to daily aluminum price swings, but metal price lag can still create a temporary favorable or unfavorable impact on earnings. For Q3 2025, they saw a favorable metal price lag of approximately $28.0 million.

• Pricing Strategy: The company's contracted pricing directly reflects the Hedged Cost of Alloyed Metal (Midwest transaction price plus alloying elements), plus a conversion fee for their specialized rolling and fabrication services. This fee is the true measure of their value-add.
• Cost Drivers: Operational costs are currently under pressure from major strategic investments. In Q3 2025 alone, they incurred approximately $20 million in non-recurring startup costs related to their Trentwood and Warrick facility expansions. That's a temporary headwind.
• End-Market Leverage: The Packaging and General Engineering segments are showing strong momentum, but the long-term growth story is tied to the recovery in commercial aerospace and the completion of the Trentwood Phase VII expansion, which will provide additional capacity for high-margin products.

Kaiser Aluminum Corporation's Financial Performance

Kaiser Aluminum's financial performance as of the third quarter of 2025 shows a strong rebound in profitability, driven by better pricing and cost management, even as shipments were temporarily down 8% year-over-year due to a planned outage at the Trentwood facility.

• Adjusted EBITDA Surge: Adjusted EBITDA for Q3 2025 was $81 million, a remarkable increase from the prior year, pushing the Adjusted EBITDA Margin to 23.2% of Conversion Revenue. That's a six-fold increase in adjusted earnings per share year-over-year.
• Deleveraging: The company is steadily improving its balance sheet health. The Net Debt Leverage Ratio improved to 3.6x as of September 30, 2025, down from 4.3x at the end of 2024. This is defintely a key sign of financial stability.
• 2025 Full-Year Outlook: Management has raised its full-year 2025 outlook, projecting an improvement in Adjusted EBITDA of 20% to 25% year-over-year. Conversion Revenue is expected to be flat to up 5% for the full year.
• Capital Investment: The company is projecting Capital Expenditures of approximately $130 million for the full year 2025, focused on strategic projects like the Trentwood Phase VII expansion, which should unlock significant margin expansion starting in 2026.
