NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS - UNAUDITED
KAISER ALUMINUM CORPORATION AND SUBSIDIARY COMPANIES
NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS – UNAUDITED
1. Basis of Presentation and Recent Accounting Pronouncements
This Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. Unless the context otherwise requires, references in these notes to interim consolidated financial statements - unaudited to “Kaiser,” “we,” “us,” “our,” “the Company” and “our Company” refer collectively to Kaiser Aluminum Corporation and its subsidiaries.
Principles of Consolidation and Basis of Presentation.
The accompanying unaudited consolidated financial statements include the accounts of our wholly owned subsidiaries and are prepared in accordance with GAAP and the rules and regulations of the SEC applicable for interim periods and, therefore, do not include all information and footnotes required by GAAP for complete financial statements. In management’s opinion, all adjustments (which include normal recurring adjustments) considered necessary for a fair presentation have been included. We have reclassified certain items in prior periods to conform to current classifications. The results of operations for our interim periods are not necessarily indicative of the results of operations that may be achieved for the entire 2025 fiscal year. The financial information as of December 31, 2024 is derived from our audited consolidated financial statements and footnotes included in our Annual Report on Form 10-K for the year ended December 31, 2024, except for the change in accounting principle disclosed in Note 14
of Notes to Interim Consolidated Financial Statements included in this Report.
Use of Estimates in the Preparation of Financial Statements.
The preparation of financial statements in accordance with GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities known to exist as of the date the financial statements are published and the reported amounts of revenues and expenses during the reporting period. Uncertainties with respect to such estimates and assumptions are inherent in the preparation of our consolidated financial statemen
ts; accordingly, it is possible that the actual results could differ from these estimates and assumptions, which could have a material effect on the reported amounts of our consolidated financial position and results of operations.
Change in Accounting Principle.
Effective January 1, 2025, the Company changed its inventory valuation methodology from LIFO to WAC for its finished products, work-in-process, and raw material inventories. This change is preferable because the Company believes that it improves the comparability of the Company's operational results between periods by removing LIFO income or charge in a period resulting from LIFO valuation and changes to historical LIFO layers. Additionally, the Company believes that the new valuation methodology better reflects the physical flow of goods and simplifies the financial close process by utilizing the WAC valuation methodology for all internal and external reporting purposes. The effects of this change have been retrospectively applied to all prior periods presented. See Note 14
for additional information regarding the change in inventory valuation methodology.
Accounting Pronouncements Issued But Not Yet Adopted
Disclosure Improvements.
In October 2023, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2023-06 (“ASU 2023-06”), Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. The guidance amends GAAP to reflect updates and simplifications to certain disclosure requirements referred to the FASB by the SEC. The amendments in ASU 2023-06 will become effective on the date which the SEC’s removal of the related disclosure becomes effective. If by June 30, 2027, the SEC does not remove the related disclosure, the pending amendment will be removed from ASC 2023-06 and it will not be effective. Adoption of ASU 2023-06 is expected to modify the disclosure and presentation requirements only and is not expected to have a material impact on our consolidated financial statements.
Income Taxes.
In December 2023, the FASB issued ASU No. 2023-09 (“ASU 2023-09”), Improvements to Income Tax Disclosures. The guidance is intended to improve income tax disclosure requirements by requiring: (i) consistent categories and greater disaggregation of information in the rate reconciliation and (ii) the disaggregation of income taxes paid by jurisdiction. The guidance makes several other changes to the annual income tax disclosure requirements. The amendments in ASU 2023-09 are effective for fiscal years beginning after December 15, 2024, with early adoption permitted, and is required to be applied prospectively with the option of retrospective application. We plan to adopt the provisions of ASU 2023-09 prospectively in the fourth quarter of fiscal 2025 and do not expect this ASU to have a material impact on our consolidated financial statements.
Disaggregation of Income Statement Expenses.
In November 2024, the FASB issued ASU No. 2024-03 (“ASU 2024-03”), Disaggregation of Income Statement Expenses. The guidance requires additional, disaggregated disclosure about certain income statement expense line items. The amendments in ASU 2024-03 are effective for annual reporting periods beginning after December
KAISER ALUMINUM CORPORATION AND SUBSIDIARY COMPANIES
NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS – UNAUDITED
15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted, and is required to be applied prospectively with the option of retrospective application. We plan to adopt the provisions of ASU 2024-03 prospectively in the fourth quarter of fiscal 2027 and continue to evaluate the disclosure requirements related to the new standard.
Credit Losses for Accounts Receivable and Contract Assets.
In July 2025, the FASB issued ASU No. 2025-05 (“ASU 2025-05”), Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides entities with a practical expedient to simplify the estimation of expected credit losses by assuming that the current conditions as of the balance sheet date will not change for the remaining life of the asset. ASU 2025-05 is effective for fiscal years beginning after December 15, 2025 and interim reporting periods within those annual reporting periods, with early adoption permitted, and should be applied prospectively. We are currently in the process of evaluating the effects of this pronouncement on our consolidated financial statements.
Accounting for Internal-Use Software.
In September 2025, the FASB issued ASU No. 2025-06 (“ASU 2025-06”), Intangibles - Goodwill and Other - Internal-Use Software (Subto
pic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which improves the operability of the guidance by removing all references to software development stages so that the guidance is neutral to different software development methods. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027 and interim reporting periods within those annual reporting periods, with early adoption permitted as of the beginning of the annual reporting period. The amendments may be applied by using a prospective transition approach, a retrospective transition approach, or a modified transition approach based on the status of the project and whether software costs were capitalized before the date of adoption. We are currently in the process of evaluating the effects of this pronouncement on our consolidated financial statements.

5. Derivatives, Hedging Programs and Other Financial Instruments
Overview
We utilize derivative instruments to manage exposure to: (i) metal price risk related to aluminum and certain alloys used as raw material for our fabrication operations; (ii) energy price risk related to natural gas and electricity used in our production processes; and (iii) foreign currency exchange rate risk related to certain equipment and service agreements. We do not use derivative financial instruments for trading or other speculative purposes. All hedging transactions are executed centrally and are overseen by a committee (“Hedging Committee”) composed of key operations and finance personnel from the management team. The scope of the Hedging Committee’s activities is reviewed with our Board of Directors.
We are exposed to counterparty credit risk on all of our derivative instruments. Our counterparties are major investment-grade financial institutions or trading companies, and our hedging transactions are governed by negotiated International Swaps and Derivatives Association Master Agreements, which generally require collateral to be posted by our counterparties above specified credit thresholds, which may adjust up or down based on changes credit ratings. As a result, we believe the risk of loss is remote and contained. The aggregate fair value of our derivative instruments that were in a net liability position was
$
0.1
million
and
$
0.8
million
at September 30, 2025 and December 31, 2024, respectively. We had
no
collateral posted as of those dates.
In addition, our firm-price customer sales commitments create incremental customer credit risk related to metal price movements. Under certain circumstances, we mitigate this risk by periodically requiring cash collateral to be posted by our customers, which we classify as deferred revenue and include as a component of Other accrued liabilities. We had
no
cash collateral posted by our customers at both September 30, 2025 and December 31, 2024.
The above described derivative instruments are typically designated as cash flow hedges. Unrealized gains and losses associated with our cash flow hedges are deferred in Other comprehensive income, net of tax, and reclassified to COGS when such hedges settle or when it is probable that the original forecasted transactions will not occur by the end of the originally specified time period. See Note 8 for the total amount of gain or loss on derivative instruments designated and qualifying as cash flow hedging instruments that was reported in AOCI, as well as the related reclassifications into earnings and tax effects. Cumulative gains and losses related to cash flow hedges are reclassified out of AOCI and recorded within COGS when the associated hedged commodity purchases impact earnings.
From time to time, we enter into commodity and foreign currency forward contracts that are not designated as hedging instruments to mitigate certain short‑term impacts, as identified. The gain or loss on these commodity and foreign currency derivatives is recognized
KAISER ALUMINUM CORPORATION AND SUBSIDIARY COMPANIES
NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS – UNAUDITED

Revolving Credit Facility
In October 2019, we entered into a Revolving Credit Facility. Joining us as borrowers under the Revolving Credit Facility are four of our wholly owned domestic operating subsidiaries: (i) Kaiser Aluminum Investments Company; (ii) Kaiser Aluminum Fabricated Products, LLC; (iii) Kaiser Aluminum Washington, LLC; and (iv) Kaiser Aluminum Warrick, LLC (collectively with the Company, the “Borrowers”). On October 14, 2025, we entered into amendment No. 5 to our Revolving Credit Facility. See Note 15, for details regarding the revised terms of the Revolving Credit Facility as amended.
The Revolving Credit Facility contains a maximum commitment amount of $
575.0
million (of which up to a maximum of $
50.0
million may be utilized for letters of credit) and, prior to the October 14, 2025 amendment, had a maturity date of April 2027.
The amount we can borrow under our Revolving Credit Facility is determined by the value of our receivables and inventory, which serve as collateral for the facility. Our effective interest rate on outstanding borrowings under the amended Revolving Credit Facility is based on the rates of Base Rate Loans and SOFR Loans (as defined in the amended Revolving Credit Facility). As of September 30, 2025, the rate for Base Rate Loans was equal to the prevailing Prime Rate plus
0.25
% (or, if borrowing availability was less than
40
% of the maximum revolving commitments,
0.50
%), while the rate for SOFR Loans, which are made for one or three month periods, was equal to the Term SOFR Reference Rate (as defined in the amended Revolving Credit Facility) plus
1.35
% (or, if borrowing availability was less than
40
% of the maximum revolving commitments,
1.60
%). Outstanding borrowings under the Revolving Credit Facility are reported within Long-term debt, net, on our Consolidated Balance Sheets. We had
no
outstanding borrowings under the Revolving Credit Facility as of
September 30, 2025
after repaying borrowings of $
290.4
million incurred during the
nine months ended September 30, 2025.
We had
no
outstanding borrowings under the Revolving Credit Facility as of or during the year ended
December 31, 2024.
The following table summarizes availability and usage of our Revolving Credit Facility as determined by a borrowing base calculated as of

7. Commitments and Contingencies
Commitments.
We have a variety of financial commitments, including purchase agreements, forward foreign exchange and forward sales contracts, indebtedness and letters of credit (see Note 5 and Note 6).
Environmental Contingencies.
We are subject to several environmental laws and regulations, potential fines or penalties assessed for alleged breaches of such laws and regulations, and potential claims based upon such laws and regulations. We are also subject to legacy environmental contingencies related to activities that occurred at our operating facilities prior to July 6, 2006, which represent the majority of our environmental accruals of
$
18.2
million
as of September 30, 2025. This accrual represents our undiscounted estimate of costs reasonably expected to be incurred based on current laws and regulations, available facts, existing technologies, and our assessment of the likely remediation actions to be taken.
Based on approved and proposed remediation action plans for the various facilities, we expect that the implementation and ongoing monitoring could occur over a period of
30
or more years. As additional facts are developed, feasibility studies are completed, remediation plans are modified, necessary regulatory approvals for the implementation of remediation are obtained, alternative technologies are developed and/or other factors change, there may be revisions to management’s estimates, and actual costs may exceed the current environmental accruals by up to
$
14.2
million
. Changes to our estimates may occur within the next
12 months
as new information becomes available.
Other Contingencies.
We are party to various lawsuits, claims, investigations and administrative proceedings that arise in connection with past and current operations. We evaluate such matters on a case-by-case basis and our policy is to vigorously contest any such claims we believe are without merit. We accrue for a legal liability when it is both probable that a liability has been incurred and the amount of the loss is reasonably estimable. Quarterly, in addition to when changes in facts and circumstances require it, we review and adjust these accruals to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. While uncertainties are inherent in the final outcome of such matters and it is presently impossible to determine the actual cost that may ultimately be incurred, we believe that we have sufficiently accrued for such matters and that the ultimate resolution of pending matters will not have a material impact on our consolidated financial position, operating results or liquidity.

The income tax provision for the quarters ended September 30, 2025 and September 30, 2024 was
$
8.3
million
and
$
2.4
million
, respectively, reflecting an effective tax rate of
17
%
and
21
%, respectively. The difference between the effective tax rate and the projected blended statutory tax rate for the quarter ended September 30, 2025 was primarily due to a decrease of
7
% related to Federal research and development credits, partially offset by an increase of
2
% related to non-deductible compensation expense. There was no material difference between the effective tax rate and the blended statutory tax rate for the quarter ended
September 30, 2024.
The income tax provision for the nine months ended September 30, 2025 and September 30, 2024 was
$
22.2

and
$
13.6

On July 4, 2025, President Trump signed into law the One Big Beautiful Bill Act ("OBBBA"). The OBBBA made permanent key elements of the Tax Cuts and Jobs Act, including 100% bonus depreciation, domestic research cost expensing, and the business interest expense limitation. ASC 740, “Income Taxes”, requires the effects of changes in tax rates and laws on deferred tax balances to be recognized in the period in which the legislation is enacted. Consequently, as of the date of enactment, the Company evaluated all deferred tax balances under the newly enacted tax law and made all changes required to the Company's Form 10-Q for the quarter ended September 30, 2025, which included no material impact to the income tax rate.
11. Earnings Per Share
Basic net income per share is computed by dividing distributed and undistributed net income allocable to common shares by the weighted-average number of common shares outstanding during the app
licable period. The basic weighted-average number of common shares outstanding during the period excludes non-vested share-based payment awards. Basic and diluted net income per share was calculated under the two-class method for the quarters and nine months ended September 30, 2025 and September 30, 2024.
The following table sets forth the computation of basic and diluted net income per share (in millions of dollars, except share and per share amounts):

Our primary line of business is the production of semi-fabricated specialty aluminum mill products, such as plate and sheet, bare and coated coils, and extruded and drawn products, primarily used in our Aero/HS Products, Packaging, GE Products, and Automotive Extrusions end markets. We operate production facilities in the United States and Canada. We have
one
operating and reportable segment. Our determination that we operate as a single segment is consistent with the financial information regularly viewed by the chief operating decision maker (“CODM”) to evaluate performance and make decisions regarding resource allocation.
The CODM uses Net income to measure segment profitability in deciding whether to reinvest profits into the segment or into other parts of the entity, such as for acquisitions or to pay dividends.

15. Subsequent Events
Dividend Declaration.
On
October 14, 2025
, we announced that our Board of Directors declared a quarterly cash dividend of
$
0.77
per common share. As such, we expect to pay approximately
$
12.8
million
(including dividend equivalents) on or about
November 14, 2025
to stockholders of record and the holders of certain restricted stock units at the close of business on
October 24, 2025
.
Revolving Credit Facility.
On October 14, 2025
, we entered into amendment No. 5 to our Revolving Credit Facility with a syndicate of commercial lenders led by Wells Fargo Bank, National Association (the “Amended Credit Facility”).
The Amended Credit Facility, among other things, (i) contains a maximum commitment amount of $
575.0
million (of which up to a maximum of $
50.0
million may be utilized for letters of credit), (ii) allows the Company to request an increase of the revolving commitments by up to an amount equal to $
200.0
million
plus an additional amount for a first-in last-out tranche, subject to certain conditions and the agreement
KAISER ALUMINUM CORPORATION AND SUBSIDIARY COMPANIES
NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS – UNAUDITED
of
one or more lenders to provide such increased commitment
, and (iii) is set to mature on the earlier of (i) March 1, 2028, if by that date the scheduled maturity of the Company’s senior notes due 2028 has not been extended to a date not earlier than 90 days after October 14, 2030, repaid in full, or refinanced or replaced on terms mutually satisfactory to the Borrowers and Wells Fargo; and (ii) October 14, 2030. The amount we can borrow under the Amended Credit Facility is determined by the value of our eligible accounts receivable and inventory and certain other assets, which serve as collateral for the Amended Credit Facility. Our effective interest rate on outstanding borrowings under the Amended Credit Facility bear interest at a rate equal to either a base rate or the secured overnight financing rate (SOFR), plus, in each case, a specified variable percentage of between
125
basis points and
150
basis points for SOFR loans (or
25
basis points and
50
basis points for base rate loans) determined by reference to the then-remaining borrowing availability under the Amended Credit Facility and, in certain instances, a fixed margin. At the time of execution of the Amended Credit Facility, we had no outstanding borrowings under the previous revolving credit facility nor did we borrow on the Amended Credit Facility. As of the effective date, under the Amended Credit Facility, there were outstanding letters of credit totaling $
14.6
million.

No assurance can be given that these are all of the factors that could cause actual results to vary materially from the forward looking statements.
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with Part I, Item 1.
“
Financial Statements
”
of this Report and our consolidated financial statements and related notes included in Part II, Item 8. “Financial Statements and Supplementary Data” of our Annual Report on Form 10-K for the year ended December 31, 2024.
Basis of Presentation
Effective January 1, 2025, we changed our inventory valuation methodology from LIFO to WAC. The impact of this change in accounting principle to both the current period and, as applied retrospectively, to the comparable period of the prior fiscal year is disclosed in Note 14 of the Form 10-Q. Prior period information provided in this Management’s Discussion and Analysis has been updated to reflect the retrospective application of the change in accounting principle.
Non-GAAP Financial Measures
This information 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 flows of the company. We have provided a reconciliation of non‑GAAP financial measures to the most directly comparable financial measure in the accompanying tables. We have also provided discussion of the reasons we believe that presentation of the non-GAAP financial measures provides useful information to investors, as well as any additional ways in which we use the non-GAAP financial measures. The non-GAAP financial measures used in the following discussions are Conversion Revenue (defined as Net sales less the Hedged Cost of Alloyed Metal, see below in “Metal Pricing Policies” discussion), Adjusted EBITDA and ratios related thereto. 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.
In the discussion of operating results below, we refer to certain items as “non-run-rate items.” For purposes of such discussion, non-run-rate items are items that, while they may recur from period-to-period: (i) are particularly material to results; (ii) affect costs primarily as a result of external market factors; and (iii) may not recur in future periods if the same level of underlying performance were to occur. Non-run-rate items are part of our business and operating environment but are worthy of being highlighted for the benefit of readers of our financial statements. Our intent is to allow users of the financial statements to consider our results both in light of and separately from such items. For a reconciliation of Adjusted EBITDA to Net income, see below in “Results of Operations - Selected Operational and Financial Information.” Reconciliations of certain forward‑looking non-GAAP financial measures to comparable
28
GAAP measures are not provided because certain items required for such reconciliations are outside of our control and/or cannot be reasonably predicted or provided without unreasonable effort.
Metal Pricing Policies
A fundamental part of our business model is to remain neutral to the impact from fluctuations in the market price for aluminum and certain alloys, thereby earning profit predominantly from the conversion of aluminum into semi-fabricated mill products. We refer to this as “metal price neutrality.” We purchase primary, rolling ingot and scrap, or recycled, aluminum, our main raw material, and alloys at prices that fluctuate on a monthly basis, and our pricing policies generally allow us to pass the current month underlying index cost of aluminum and certain alloys through to our customers so that we remain neutral to metal pricing. We may also enter into firm-price customer sales agreements that specify a firm underlying metal price plus a conversion price. Firm-price sales agreements create price exposure for us, which we mitigate through hedging and related programs with an objective to remain metal price neutral. Additionally, we have certain contracts that may adjust certain alloy prices for a forward period based on an average prior period cost for such alloys. As a result, until the selling price resets, we can experience an adverse impact when alloy prices increase and a favorable impact when alloy prices decrease.
In order to allow users of our financial statements to consider the impact of aluminum and alloy cost on our Net sales, we disclose Net sales as well as Conversion Revenue, which is Net sales less the Hedged Cost of Alloyed Metal. As used in this discussion, “Hedged Cost of Alloyed Metal” is the cost of aluminum at the average MWTP plus the cost of alloying elements and any realized gains and/or losses on settled hedges related to the metal sold in the referenced period. The average MWTP of aluminum reflects the primary aluminum supply/demand dynamics in North America. For a reconciliation of Conversion Revenue to Net sales, see below in “Results of Operations - Selected Operational and Financial Information.”
Business Overview
We manufacture and sell semi-fabricated specialty aluminum mill products for the following end market applications: (i) Aero/HS Products; (ii) Packaging; (iii) GE Products; and (iv) Automotive Extrusions. Our fabricated aluminum mill products include flat-rolled (plate, sheet and coil), extruded (rod, bar, hollows and shapes), drawn (rod, bar, pipe, tube and wire) and certain cast aluminum products. The sophistication of our products is due to the metallurgy and physical properties of the metal and the special characteristics that are required for particular end uses. We strategically choose to serve technically challenging applications for which we can deploy our core metallurgical and process technology capabilities to produce highly engineered mill products with differentiated characteristics that present opportunities for us to receive premium pricing and to create long-term profitable growth.
With respect to the global market for flat-rolled aluminum mill products, our focus is on heat treat plate and sheet for applications that require higher strength and other desired product attributes that cannot be achieved by common alloy rolled products. The primary end market applications of flat-rolled heat treat plate and sheet, which are produced at Trentwood, are Aero/HS Products (which we sell globally) and GE Products (which we predominantly sell within North America). The primary end market application of bare and coated aluminum coil, which are produced at Warrick, is Packaging (which we sell in North America). Our Packaging products require demanding attributes and can be further processed to include coating and slitting depending on customer specifications.
In the areas of aluminum extrusions, we focus on demanding Aero/HS Products, GE Products, and Automotive Extrusions that require high strength, machinability or other specific properties where we can create and maintain a defensible competitive position because of our technical expertise, strong production capability and high product quality. Our 10 active extrusion/drawing facilities, nine of which are in the United States and one of which is in Canada, serve primarily North American demand for aerospace, general engineering, or automotive applications. Additionally, we have a facility in Columbia, New Jersey, that focuses on multi-material advanced manufacturing methods and techniques, which include multi-axis computer numerical control machining, additive manufacturing (“3D Printing”), welding and fabrication for demanding aerospace and defense, high technology, general industrial, and automotive applications. Our consolidated Net sales for the nine months ended September 30, 2025 totaled $2,444.0 million on approximately 834.2 million pounds shipped from our facilities. We employed approximately 3,900 people at September 30, 2025.
We have long-standing relationships with our customers, which consist primarily of blue-chip companies including leading aerospace and automotive manufacturers, tier one aerospace and automotive suppliers, food and beverage packaging manufacturers, and metal service centers. Approximately 70% of our shipments is sold direct to manufacturers or tier one suppliers and approximately 30% is sold to metal service centers. In our served markets, we seek to be the supplier of choice by pursuing “Best in Class” customer satisfaction driven by quality, availability, service and delivery performance. We believe we differentiate our product portfolio through our broad product offering and our
Kaiser
Select
®
products, which are engineered and manufactured to deliver enhanced product characteristics with improved consistency, so as to result in better performance, lower waste and, in many cases, lower production cost for our customers.
29
As part of the manufacturing process, we purchase primary, rolling ingot and scrap, or recycled, aluminum, our main raw material, and alloys at prices that fluctuate on a daily basis. We typically purchase scrap at a discount to the MWTP which can vary depending on market dynamics and availability. As a result, we can experience an adverse impact when scrap discounts decrease and a favorable impact when scrap discounts increase. Additionally, as our manufacturing process takes approximately one to four months to complete, depending on the complexity and additional fabrication processes required, and we value our inventory on a weighted average cost methodology, the weighted average cost of our inventory may lag the current metal selling cost. As such, our results may reflect a favorable impact when metal prices increase and adverse impact when metal prices decrease. We refer to this as Metal Price Lag, which can be influenced not only by the amount of change in price but also the volatility and timing of the change of metal prices during the reporting period.

Adjusted to reflect the retrospective change in inventory valuation methodology from LIFO to WAC. See Note 14 of Notes to Interim Consolidated Financial Statements included in this Report for further discussion.
Of the $107.1 million increase in Hedged Cost of Alloyed Metal, $136.1 million was due to an increase in hedged metal prices (see above in our “Net Sales” discussion for further details), partially offset by a $29.0 million decrease attributed to lower shipment volume. The $49.4 million decrease in manufacturing costs was primarily due to favorable metal consumption and lower shipment volume, partially offset by higher costs associated with a planned partial outage at Trentwood for the Phase VII capacity expansion project and the start-up of the fourth coating line at Warrick. The $4.0 million decrease in other cost of products sold was primarily driven by a decrease in legacy environmental costs and a decrease in major maintenance costs. The $1.8 million decrease in freight costs was primarily due to lower shipment volume. For a further discussion of the comparative results of operations for the quarters ended September 30, 2025 and September 30, 2024, see below in “Selected Operational and Financial Information.”
COGS for the nine months ended September 30, 2025 totaled $2,125.0 million, or 87% of Net sales, compared to $1,997.1 million, or 88% of Net sales, for the nine months ended September 30, 2024. The total increase reflected the following (in millions of dollars):

Adjusted EBITDA includes favorable Metal Price Lag of approximately $28.0 million and approximately $7.0 million for the quarters ended September 30, 2025 and September 30, 2024, respectively, and favorable Metal Price Lag of approximately $64.0 million and approximately $31.0 million for the nine months ended September 30, 2025 and September 30, 2024, respectively.
Adjusted EBITDA for the quarter ended September 30, 2025 was $35.1 million higher than Adjusted EBITDA for the quarter ended September 30, 2024. Adjusted EBITDA for the quarter ended September 30, 2025 was impacted by: (i) improved product pricing and mix; (ii) favorable metal costs; and (iii) lower major maintenance costs. This was partially offset by: (i) higher manufacturing costs primarily due to costs associated with the Trentwood Phase VII outage and startup of the fourth coating line at Warrick; (ii) lower sales volume; and (iii) higher employee and employee-related costs. See above in “Consolidated Results of Operations” for further details.
Adjusted EBITDA for the nine months ended September 30, 2025 was $48.0 million higher than Adjusted EBITDA for the nine months ended September 30, 2024. Adjusted EBITDA for the nine months ended September 30, 2025 was impacted by: (i) improved product pricing and mix and (ii) favorable metal costs.

Borrowing availability under the Revolving Credit Facility was determined by a borrowing base calculated as of September 30, 2025 and December 31, 2024.
We place our cash in bank deposits with high credit quality financial institutions. See Note 12 of Notes to Interim Consolidated Financial Statements included in this Report for information regarding restricted cash at September 30, 2025.
We had no outstanding borrowings under the Revolving Credit Facility as of September 30, 2025 after repaying borrowings of $290.4 million incurred during the nine months ended September 30, 2025. We had no outstanding borrowings under the Revolving Credit Facility during the year ended December 31, 2024. See below in “Sources of Liquidity” for a further discussion of subsequent borrowing activity. See Note 6 of Notes to Interim Consolidated Financial Statements included in this Report.

Cash provided by operating activities for the nine months ended September 30, 2024 reflected results of business activity described above in our “Consolidated Results of Operations” discussion, as well as the following working capital changes: (i) an increase in trade and other receivables of $33.7 million, primarily due to increased metal prices and sales mix; (ii) an increase in accounts payable of $17.5 million, primarily due to the timing of payments and higher metal cost; (iii) an increase in inventory of $8.0 million, primarily due to strong customer demand in Packaging end market; and (iv) a decrease in accrued liabilities of $11.6 million, primarily due to timing and a decrease in general business activities.
See Statements of Consolidated Cash Flows included in this Report for further details on our cash flows from operating, investing, and financing activities for the nine months ended September 30, 2025 and September 30, 2024.
Sources of Liquidity
Our most significant sources of liquidity include available cash and cash equivalents, borrowing availability under the Revolving Credit Facility, and cash flows generated from operations. We believe we have sufficient liquidity to fund our operations and meet our short-term and long-term financial obligations.
Our Revolving Credit Facility and Senior Notes have covenants that, we believe, allow us to operate our business with limited restrictions and significant flexibility for the foreseeable future. We do not believe that the covenants contained in the Revolving Credit Facility are reasonably likely to limit our ability to raise additional debt or equity should we choose to do so during the next 12 months, nor do we believe it is likely that during the next 12 months we will trigger the availability threshold that would require measuring and maintaining a fixed charge coverage ratio. On October 14, 2025, we entered into the Amended Credit Facility to, among other things, extend the maturity date to the earlier of (i) March 1, 2028, if by that date the scheduled maturity of the Company’s senior notes due 2028 has not been extended to a date not earlier than 90 days after October 14, 2030, repaid in full, or refinanced or replaced on terms mutually satisfactory to the Borrowers and Wells Fargo; and (ii) October 14, 2030, and incorporate certain improved terms offering greater operational flexibility.
See Note 15 of Notes to Interim Consolidated Financial Statements included in this Report for further details.
At October 20, 2025, we had no outstanding borrowings under the Revolving Credit Facility. See Note 9 of Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2024 for a description of our Revolving Credit Facility.
We engage in certain customer-based supply chain financing programs to accelerate the receipt of payment for outstanding accounts receivable from certain customers. Costs of these programs are typically reimbursed to us by the customer. Receivables transferred under these customer-based supply chain financing programs generally meet the requirements to be accounted for as sales resulting in the derecognition of such receivables from our consolidated balance sheets. Receivables involved with these customer‑based supply chain finance programs for the quarter ended September 30, 2025 constituted approximately 31% of our Net sales. See Note 9 of Notes to Interim Consolidated Financial Statements included in this Report for further details with respect to these supply chain financing programs.
Material Cash Requirements
See Note 9 of Notes to Consolidated Financial Statements included in Part II, Item 8. “Financial Statements and Supplementary Data” in our Annual Report on Form 10-K for the year ended December 31, 2024 for mandatory principal and cash interest payments on the outstanding borrowings.
We do not believe that covenants in the indentures governing the Senior Notes are reasonably likely to limit our ability to obtain additional debt or equity financing should we choose to do so during the next 12 months.
Except as otherwise disclosed in this Report, there has been no material change in our material cash requirements from significant contractual obligations, commercial commitments, or off-balance sheet arrangements other than in the ordinary course of business since December 31, 2024.
Capital Expenditures and Investments
We strive to strengthen our competitive position across our end markets through strategic capital investment. Significant investments over the past decade have positioned us well with increased capacity and expanded manufacturing capabilities while more recent capital projects have focused on further enhancing manufacturing cost efficiency, improving product quality and promoting operational security, which we believe are critical to maintaining and strengthening our position in an increasingly competitive market
36
environment. At our Trentwood facility, a significant portion of our capital spending over the past several years related to modernization projects, which focused on equipment upgrades throughout the process flow to reduce conversion costs, increase efficiency, and further improve our competitive cost position on all products produced at Trentwood. These investments also focused on modernizing legacy equipment and the process flow for thin gauge plate to achieve
Kaiser
Select
®
quality enhancements for these Aero/HS Products and GE Products. These improvements have allowed us to gain incremental manufacturing capacity to enable future sales growth. At our Warrick facility, we have invested significant capital to expand our capacity and quality in higher margin coated products.
Our capital investment plans remain focused on supporting demand growth through capacity expansion, sustaining our operations, enhancing product quality and increasing operating efficiencies. We anticipate total capital spending in 2025 of approximately $130.0 million. We expect to continue to deploy capital thoughtfully so that investment decisions align with demand expectations in order to maximize the earnings potential of the business and maintain financial strength and flexibility.
Capital investments will be funded using cash generated from operations, available cash and cash equivalents, borrowings under the Revolving Credit Facility and/or other third-party financing arrangements. The level of anticipated capital expenditures may be adjusted from time to time depending on our business plans, our price outlook for fabricated aluminum products, our ability to maintain adequate liquidity, and other factors. No assurance can be provided as to the timing of any such expenditures or the operational benefits expected therefrom.
Dividends
We have consistently paid a quarterly cash dividend since the second quarter of 2007 to holders of our common stock, including holders of restricted stock. Nevertheless, as in the past, the future declaration and payment of dividends, if any, will be at the discretion of our Board of Directors and will depend on a number of factors, including our financial and operating results, including the availability of surplus and/or net profits, liquidity position, anticipated cash requirements and contractual restrictions under our Revolving Credit Facility, the indentures for our Senior Notes or other indebtedness we may incur in the future. We can give no assurance that dividends will be declared and paid in the future.
We also pay quarterly dividend equivalents to the holders of certain restricted stock units. Holders of performance shares are not paid a quarterly dividend equivalent, but instead are entitled to receive, in connection with the issuance of underlying shares of common stock for performance shares that ultimately vest, a one-time payment equal to the dividends such holders would have received if the number of such shares of common stock so issued had been held of record by such holders from the date of grant of such performance shares through the date of such issuance.
See our Statements of Consolidated Stockholders’ Equity and Note 15 of Notes to Interim Consolidated Financial Statements included in this Report for information regarding dividends paid during the quarters ended September 30, 2025 and September 30, 2024, and declared subsequent to September 30, 2025.
Repurchases of Common Stock
We suspended share repurchases as of March 2020. We will continue to assess share repurchases as a part of our capital allocation priorities and strategic investment opportunities identified to support further growth in our business. At September 30, 2025, $93.1 million remained authorized and available for future repurchases of common stock under our stock repurchase program.
See our Statements of Consolidated Stockholders’ Equity included in this Report for information regarding minimum statutory tax withholding obligations arising during the quarters ended September 30, 2025 and September 30, 2024 in connection with the vesting of non‑vested shares, restricted stock units, and performance shares.
Critical Accounting Estimates and Policies
Our consolidated financial statements are prepared in accordance with GAAP. In connection with the preparation of our financial statements, we are required to make assumptions and estimates about future events and apply judgments that affect the reported amounts of assets, liabilities, revenue and expenses and the related disclosures. We base our assumptions, estimates and judgments on historical experience, current trends and other factors that management believes to be relevant at the time our consolidated financial statements are prepared. On a regular basis, management reviews the accounting policies, assumptions, estimates and judgments to ensure that our financial statements are presented fairly and in accordance with GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates and such differences could be material.
37
Our significant accounting policies are discussed in Note 1 of Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2024. We discuss our critical accounting estimates in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10‑K for the year ended December 31, 2024. There have been no material changes in our critical accounting estimates and policies since December 31, 2024.

Item 3.
Quantitative and Qualitat
ive Disclosures About Market Risk
The following quantitative and qualitative disclosures about market risk should be read in conjunction with Note 5 and Note 8 of Notes to Interim Consolidated Financial Statements included in this Report. Our operating results are sensitive to changes in the prices of primary aluminum, certain alloying metals, natural gas, electricity, and foreign currency, and also depend to a significant degree upon the volume and mix of products sold to customers. We have historically utilized hedging transactions to lock in a specified price or range of prices for certain products which we sell or consume in our production process, and to mitigate our exposure to changes in energy prices.
Aluminum
During the nine months ended September 30, 2025 and September 30, 2024, settlements of derivative contracts were for 88.8 million pounds and 117.3 million pounds, respectively, of hedged shipments sold on pricing terms that created aluminum price risk for us. At September 30, 2025, we had derivative contracts with respect to approximately 34.6 million and 6.0 million pounds to hedge sales to be made in the remainder of 2025 and 2026, respectively, on pricing terms that create aluminum price risk for us.
Based on the aluminum derivative positions held by us to hedge firm-price customer sales agreements, we estimate that a $0.10/lb decrease in the LME market price of aluminum as of September 30, 2025 and December 31, 2024, with all other variables held constant, would have resulted in an unrealized mark-to-market loss of $4.1 million and $4.7 million, respectively, with corresponding changes to the net fair value of our aluminum derivative positions. Additionally, we estimate that a $0.05/lb decrease in the Midwest premium for aluminum as of September 30, 2025 and December 31, 2024, with all other variables held constant, would have resulted in an unrealized mark-to-market loss of $2.0 million and $2.0 million, respectively, with corresponding changes to the net fair value of our aluminum derivative positions.
Alloying Metals
We are exposed to the risk of fluctuating prices of certain alloying metals, especially copper, zinc, and magnesium, to the extent that changes in their prices do not highly correlate with price changes for aluminum. Copper, zinc, magnesium, and certain other metals are used in our remelt operations to cast rolling ingot and extrusion billet with the proper chemistry for our products. From time to time, we enter into forward contract swaps and/or physical delivery commitments with third parties to mitigate our risk from fluctuations in the prices of these alloys. As of September 30, 2025, we had forward swap contracts with settlement dates designed to align with the timing of scheduled purchases of zinc and copper by our manufacturing facilities. We estimate that a $0.10/lb decrease in the market price of zinc and copper as of September 30, 2025 and December 31, 2024, with all other variables held constant, would have resulted in an unrealized mark‑to‑market loss of $0.7 million and $0.9 million, respectively, with corresponding changes to the net fair value of our zinc and copper derivative positions.
38
Energy
We are exposed to the risk of fluctuating prices for natural gas and electricity. We, from time to time, in the ordinary course of business, enter into hedging transactions and/or firm-price physical delivery commitments with third parties to mitigate our risk from fluctuations in natural gas and electricity prices. We estimate that a $1.00 per mmbtu decrease in natural gas prices would have resulted in an unrealized mark-to-market loss of $3.3 million and $2.8 million as of September 30, 2025 and December 31, 2024, respectively, with corresponding changes to the net fair value of our natural gas derivative positions. We had no outstanding electricity derivative positions as of September 30, 2025 and December 31, 2024.
Foreign Currency
As of September 30, 2025, we hedged the foreign currency exchange rate risk related to certain lease transactions and equipment purchases denominated in Euros using forward swap contracts with settlement dates through July 2027. We estimate that a 10% decrease in the exchange rate of our hedged foreign currencies to U.S. dollars would have resulted in an unrealized mark-to-market loss of $0.2 million and $0.8 million as of September 30, 2025 and December 31, 2024, respectively, with corresponding changes to the net fair value of our foreign currency derivative positions.
Item 4.
Controls
and Procedures
Evaluation of Disclosure Controls and Procedures.
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934 is processed, recorded, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including the principal executive officer and principal financial officer, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures was performed as of the end of the period covered by this Report under the supervision of and with the participation of our management, including the principal executive officer and principal financial officer. Based on that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of September 30, 2025 at the reasonable assurance level.
Changes in Internal Control Over Financial Reporting.
We had no changes in our internal control over financial reporting during the nine months ended September 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Under our equity incentive plan, participants may elect to have us withhold common shares to satisfy minimum statutory tax withholding obligations arising from the recognition of income and the vesting of restricted stock, restricted stock units, and performance shares. When we withhold these shares, we are required to remit to the appropriate taxing authorities the market price of the shares withheld by us on the date of withholding. The withholding of common shares by us could be deemed a purchase of such common shares.
