FOR IMMEDIATE RELEASE

Kaiser Aluminum Announces Quarterly Dividend Payment and
Fourth Quarter Charges

Fourth Quarter and Full-Year 2008 Earnings Conference
Call Date Scheduled

FOOTHILL RANCH, Calif. — January 15, 2009 — Kaiser Aluminum Corporation (NASDAQ:KALU) today announced that its Board of Directors has declared a quarterly cash dividend payment of $0.24 per share on the Company’s outstanding common stock. This dividend will be payable on February 13, 2009 to shareholders of record at the close of business on January 26, 2009.

The Company also announced that it expects to report significant fourth quarter non-run-rate and predominately non-cash charges related to the following:

• Mark-to-market losses on hedging transactions;

• A lower-of-cost or-market adjustment to inventory driven by the significant decline in metal prices;

• The impairment of its 49% equity interest in Anglesey Aluminium (“Anglesey”) as a result of the expected full curtailment of Anglesey’s smelting operations at the end of September 2009 when its current power contract expires; and

• Restructuring charges related to the recently announced closure of the Tulsa, Okla. facility as well as reductions at the Bellwood, Va. facility.

The combined total of the predominantly non-cash charges is expected to be approximately $185 million pretax, subject to final audit. Approximately, $135 million of these pretax charges is primarily related to the decline in metal prices. The Company expects to report a net loss for the fourth quarter and full year 2008 as a result of these combined charges.

Due to these charges and resulting net income impact, Kaiser’s revolving credit agreement precluded additional share repurchases and the payment of its normal quarterly dividend due to a limitation based on net earnings (measured on a GAAP basis). As a result, the Company amended its revolving credit agreement to permit continued quarterly dividend payments with the requirement that it maintains availability in excess of $100 million under the revolving credit facility. The amendment also prohibits future share repurchases without lender approval and increases fees and borrowing costs of the revolving credit facility. The Company continues to generate strong cash flow that supports the ongoing dividend while

maintaining sufficient liquidity and ample availability under its $265 million revolving credit facility.

Additional information will be provided with release of the Company’s fourth quarter and full year 2008 financial and operating results on Tuesday, February 17, 2009 after the market closes. Kaiser Aluminum will host its quarterly conference call on Wednesday, February 18, 2009 at:
