As previously disclosed in the Current Report on Form 8-K of Kaiser Aluminum Corporation (the “Company”), filed with the Securities and Exchange Commission (the “SEC”) on May 24, 2012, the Company issued $225,000,000 aggregate principal amount of its 8.250% Senior Notes due 2020 (the “Outstanding Notes”) on May 23, 2012. The Outstanding Notes are guaranteed by certain domestic subsidiaries of the Company (the “Guarantors”). The Company and the Guarantors intend to file a registration statement on Form S-4 with the SEC (the “Exchange Registration Statement”) to register the Company's 8.250% Senior Notes due 2020 (the “Exchange Notes”) and the guarantees of the Exchange Notes (the “Exchange Guarantees”). The Exchange Notes and Exchange Guarantees will be issued in exchange for the Outstanding Notes and related outstanding guarantees thereof, respectively.

In connection with the Exchange Registration Statement, the Company is updating Part I, Item 1. Financial Statements, attached hereto as Exhibit 99.1 and incorporated herein by reference, that was originally included in the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2012 (the “2012 10-Q”), solely to include supplemental guarantor disclosures required by Section 210.3-10(f) of Regulation S-X.

The information included in and with this Current Report on Form 8-K (this “Current Report”) is presented for informational purposes only, and there has been no change to the Company's previously reported consolidated net operating results, financial condition or cash flows. This Current Report does not reflect events occurring subsequent to the filing of the 2012 10-Q with the SEC on April 26, 2012 and does not modify or update the disclosures therein in any way, other than as required to reflect the financial information of the Guarantors as described above and set forth in Exhibit 99.1 attached hereto.
