<sup>1.</sup>Adjusted to reflect the retrospective change in inventory valuation methodology from last in, first out ("LIFO") to weighted average costs ("WAC") for certain inventories.

<sup>2.</sup>Hedged Cost of Alloyed Metal for the quarters ended June 30, 2025 and June 30, 2024 included $449.5 million and $408.0 million, respectively, reflecting the cost of aluminum at the average Midwest Transaction Price and the cost of alloys used in the production process, as well as metal price exposure on shipments that the Company hedged with realized gains upon settlement of $0.6 million and $3.5 million, respectively, all of which were included within both Net sales and Cost of products sold, excluding depreciation and amortization in the Company's Statements of Consolidated Income. Hedged Cost of Alloyed Metal for the six months ended June 30, 2025 and June 30, 2024 included $868.3 million and $775.1 million, respectively, reflecting the cost of aluminum at the average Midwest Transaction Price and the cost of alloys used in the production process, as well as metal price exposure on shipments that the Company hedged with realized gains upon settlement of $5.2 million in the six months ended June 30, 2025, all of which were included within both Net sales and Cost of products sold, excluding depreciation and amortization in the Company's Statements of Consolidated Income. There were no gains or losses upon settlement of hedges for metal price exposure on shipments for the six months ended June 30, 2024.

<sup>3.</sup>Diluted shares for EPS are calculated using the two-class method.

<sup>4.</sup>Adjusted numbers exclude non-run-rate items. For all Adjusted numbers and EBITDA refer to Reconciliation of Non-GAAP Measures.

<sup>5.</sup>Adjusted EBITDA = Consolidated operating income, excluding operating non-run-rate items, plus Depreciation and amortization.

<sup>6.</sup>Adjusted EBITDA margin = Adjusted EBITDA as a percent of Conversion Revenue.

<sup>7.</sup>Includes favorable metal price lag of approximately $14.0 million and approximately $19.0 million for the quarters ended June 30, 2025 and June 30, 2024, respectively, and favorable metal price lag of approximately $36.0 million and approximately $24.0 million for the six months ended June 30, 2025 and June 30, 2024, respectively. Metal price lag represents management's estimate of the financial impact resulting from the timing difference between aluminum prices included within Hedged Cost of Alloyed Metal and the weighted average market price for aluminum during the period, based on the Midwest Transaction Price ("MWTP"), multiplied by our shipment volume during the periods. Metal price lag will generally increase our earnings in times of rising primary aluminum prices and decrease our earnings in times of declining primary aluminum prices.

 Please refer to GAAP financial statements, totals may not sum due to rounding.

**Available Information**

For more information, please visit the Company's website at www.kaiseraluminum.com*.* The website includes a section for investor relations under which the Company provides notifications of news or announcements regarding its financial performance, including Securities and Exchange Commission (SEC) filings, investor events, and earnings and other press releases.

**Non-GAAP Financial Measures**

This earnings release contains certain non-GAAP financial measures. A "non-GAAP financial measure" is defined as a numerical measure of a company's financial performance that excludes or includes amounts so as to be different than the most directly comparable measure calculated and presented in accordance with GAAP in the statements of income, balance sheets, or statements of cash flow of the Company. Pursuant to the requirements of Regulation G, the Company has provided a reconciliation of non-GAAP financial measures to the most directly comparable financial measure in the accompanying tables.

------

The non-GAAP financial measures used within this earnings release are Conversion Revenue, Adjusted operating income, Adjusted EBITDA, Adjusted net income, and Adjusted earnings per diluted share which exclude non-run-rate items and ratios related thereto. As more fully described in these reports, "non-run-rate" items are items that, while they may occur from period to period, are particularly material to results, impact costs primarily as a result of external market factors and may not occur in future periods if the same level of underlying performance were to occur. These measures are presented because management uses this information to monitor and evaluate financial results and trends and believes this information to also be useful for investors. Reconciliations of certain forward looking non-GAAP financial measures to comparable GAAP measures are not provided because certain items required for such reconciliations are outside of the Company's control and/or cannot be reasonably predicted or provided without unreasonable effort.

**Forward-Looking Statements**

This press release contains statements based on management's current expectations, estimates and projections that constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995 involving known and unknown risks and uncertainties that may cause actual results, performance or achievements of the Company to be materially different from those expressed or implied. These factors include: (a) the effectiveness of management's strategies and decisions, including strategic investments, capital spending strategies, cost reduction initiatives, sourcing strategies, process and countermeasures implemented to address operational and supply chain challenges, and the execution of those strategies; (b) the execution and timing of strategic investments; (c) general economic and business conditions, including the impact of geopolitical factors and governmental and other actions taken in response, tariffs, cyclicality, reshoring, labor challenges, supply interruptions, scrap availability and pricing, customer operation disruptions, customer inventory imbalances and supply chain issues and other conditions that impact demand drivers in the aerospace/high strength, packaging, general engineering, automotive extrusions and other end markets we serve; (d) the Company's ability to participate in mature and anticipated new automotive programs expected to launch in the future and successfully launch new automotive programs; (e) changes or shifts in defense spending due to competing national priorities; (f) pricing, market conditions and the Company's ability to effectively execute its commercial and labor strategies, pass through cost increases, including the institution of surcharges, and flex costs in response to inflation, volatile commodity costs and changing economic conditions; (g) developments in technology; (h) the impact of the Company's future earnings, cash flows, financial condition, capital requirements and other factors on its financial strength and flexibility; (i) new or modified statutory or regulatory requirements; (j) the successful integration of the acquired operations and technologies; (k) stakeholder, including regulator and customer, views regarding the Company's sustainability goals and initiatives and the impact of factors outside of the Company's control on such goals and initiatives; and (l) other risk factors summarized in the Company's reports filed with the Securities and Exchange Commission including the Company's Form 10-K for the year ended December 31, 2024.

<sup>1.</sup>Adjusted to reflect the retrospective change in inventory valuation methodology from LIFO to WAC for certain inventories.

<sup>2.</sup>Mark-to-market loss on derivative instruments represents the loss on non-designated commodity hedges. Adjusted EBITDA reflects the impact realized upon settlement.

<sup>3.</sup>NRR is an abbreviation for non-run-rate; NRR items are pre-tax.

<sup>4.</sup>Other operating NRR items primarily represent the impact of adjustments to legacy environmental accruals.

<sup>5.</sup>Adjusted EBITDA = Consolidated operating income, excluding operating NRR items, plus Depreciation and amortization.

<sup>6.</sup>Non-operating NRR items typically represent the impact of non-cash net periodic benefit cost related to the Salaried VEBA excluding service cost, gains (losses) recorded from the sale of non-operating assets, and gains recorded from business interruption insurance recoveries.

<sup>7.</sup>Diluted shares for EPS are calculated using the two-class method.

<sup>8.</sup>Includes favorable metal price lag of approximately $14.0 million and approximately $19.0 million for the quarters ended June 30, 2025 and June 30, 2024, respectively, and favorable metal price lag of approximately $36.0 million and approximately $24.0 million for the six months ended June 30, 2025 and June 30, 2024, respectively. Metal price lag represents management's estimate of the financial impact resulting from the timing difference between aluminum prices included within Hedged Cost of Alloyed Metal and the weighted average market price for aluminum during the period, based on the Midwest Transaction Price, multiplied by our shipment volume during the periods. Metal price lag will generally increase our earnings in times of rising primary aluminum prices and decrease our earnings in times of declining primary aluminum prices.

Totals may not sum due to rounding.
