Kaiser Aluminum Reports First Quarter 2007 Financial Results

-- Operating income for fabricated products was $41 million

-- Record heat treat plate shipments for fifth consecutive quarter driven by strength in demand for aerospace and defense applications

-- Trentwood expansion on schedule

FOOTHILL RANCH, Calif.--(BUSINESS WIRE)--

Kaiser Aluminum Corporation (NASDAQ:KALU) today reported net income of $17 million for the first quarter 2007, which is net of an income tax provision of $16 million, approximately $11 million of which is non-cash. The non-cash tax provision is recorded despite the existence of significant net operating loss carryforwards and other tax attributes, the benefits of which are reflected in stockholder equity in accordance with fresh start accounting. This compares to $38 million of net income for the same period in 2006.

Net sales for the first quarter of 2007 increased 17 percent to $392 million, compared to $336 million for the first quarter of 2006. The increase is attributable to the pass-through to customers of significantly higher metal prices as well as improved value-added pricing in fabricated products.

"The company continues to deliver strong results, led by robust demand for aerospace and defense applications partially offset by soft demand in ground transportation and other industrial applications for fabricated products," said Jack A. Hockema, chairman, president, and CEO of Kaiser Aluminum.

Fabricated Products - Operating income in fabricated products was $41 million for the first quarter of 2007. In the prior year quarter, operating income of $45 million included $9 million of favorable non-run-rate items.

Strong shipments for aerospace and defense applications in the first quarter of 2007 contributed to a richer product mix. Value-added pricing was also favorable. The positive income impact from favorable mix and improved value-added pricing was partially offset by soft demand in ground transportation and other industrial applications for fabricated products as well as adverse cost performance. In addition, operating income improved approximately $2 million due to lower depreciation resulting from the company's implementation of fresh start accounting.

"Strong demand coupled with recently-added capacity enabled record heat treat plate shipments for the fifth consecutive quarter," added Hockema. "The first two heat treat plate furnaces in the Trentwood expansion are fully operational. The project remains on schedule, and in early 2008 we expect the new stretcher and third heat treat furnace to provide additional product capabilities and further increase capacity."

Primary Products - Operating income in the primary products segment was $4 million for the first quarter of 2007, compared to $9 million for the same period of 2006. The 2007 result included non-run-rate mark-to-market losses of $4 million, which was $9 million unfavorable when compared to the same period in 2006. Favorable impacts from higher primary aluminum prices were partially offset by higher alumina costs.

Notes follow.
(1) The Company and its subsidiaries which included all of the
 Company's core fabricated products facilities and operations and a
 49% interest in Anglesey Aluminium Limited ("Anglesey"), which owns
 an interest in a smelter in the United Kingdom, emerged from chapter
 11 on July 6, 2006 (the "Effective Date") pursuant to the Company's
 Second Amended Plan of Reorganization (the "Plan"). Pursuant to the
 Plan, all material pre-petition debt, pension, post-retirement
 medical obligations and asbestos and other tort liabilities, along
 with other pre-petition plans (which in total aggregated at June 30,
 2006 approximately $4.4 billion) were addressed and resolved.
 Pursuant to the Plan, the interests of the Company's pre-emergence
 stockholders were cancelled without consideration.  Equity of the
 newly emerged Kaiser was issued and delivered to a third-party
 disbursing agent for distribution to claimholders pursuant to the
 Plan.

As a result of the Company's emergence from chapter 11 on the
 Effective Date, the Company applied "fresh start" accounting to its
 opening July 2006 consolidated financial statements as required by
 American Institute of Certified Professional Accountants ("AICPA")
 Statement of Position 90-7 ("SOP 90-7"), Financial Reporting by
 Entities in Reorganization Under the Bankruptcy Code. As such, the
 Company adjusted its stockholders' equity to equal the reorganization
 value at the Effective Date. Items such as accumulated depreciation,
 accumulated deficit and accumulated other comprehensive income (loss)
 were reset to zero. The Company allocated the reorganization value to
 its individual assets and liabilities based on their estimated fair
 value. Items such as current liabilities, accounts receivable, and
 cash reflected values similar to those reported prior to emergence.
 Items such as inventory, property, plant and equipment, long-term
 assets and long-term liabilities were significantly adjusted from
 amounts previously reported.

The accompanying financial statements include the financial statements
 of the Company both before and after emergence from chapter 11
 bankruptcy in July, 2006. Financial information related to the
 Company after emergence is generally referred to throughout this
 report as "Successor" information. Information of the Company before
 emergence is generally referred to as "Predecessor" information. The
 financial information of the Successor entity is not comparable to
 that of the Predecessor given the impacts of the Plan, implementation
 of fresh start reporting and other factors.

Income (loss) per share of the Predecessor is not meaningful because
 all equity interests of the Company's stockholders prior to the
 Company's July 6, 2006 emergence from chapter 11 were cancelled
 without consideration.

(2) Selling, administrative, research and development, and general for
 the quarter ended March 31, 2007 includes non-cash compensation
 charges of $2.0 related to outstanding non-vested stock and
 restricted stock units.

(3) Other operating (benefits) charges, net, for the quarters ended
 March 31, 2007 and 2006, was as follows:

                                            ============= ============

(4) Provision for income taxes for continuing operations for the
 quarters ended March 31, 2007 and 2006 include foreign income
 provisions of approximately $4.6 and $6.1, respectively.  Foreign
 taxes for the post emergence period primarily represent Canadian
 income taxes in respect of operations of the London, Ontario facility
 and United Kingdom income taxes in respect of the Company's ownership
 interest in Anglesey.

Although the Company has between approximately $975 and $1,050 of tax
 attributes available to offset the impact of future income taxes, the
 Company does not meet the "more likely than not" criteria for
 recognition of such attributes primarily because the Company does not
 have sufficient history of paying taxes. As such, the Company
 recorded a full valuation allowance against the amount of tax
 attributes available and no deferred tax asset was recognized. The
 benefit associated with any reduction of the valuation allowance is
 first utilized to reduce intangible assets with any excess being
 recorded as an adjustment to Stockholders' equity rather than as a
 reduction of income tax expense. Therefore, despite the existence of
 such tax attributes, the Company expects to record a full statutory
 tax provision in future periods and, therefore, the benefit of any
 tax attributes realized will only affect future balance sheets and
 statements of cash flows. If the Company ultimately determines that
 it meets the "more likely than not" recognition criteria, the amount
 of net operating loss carryforwards and the other deferred tax assets
 would be recorded on the balance sheet and would be recorded as an
 adjustment to stockholders' equity.

(5) Basic earnings per share are computed by dividing earnings by the
 weighted average number of common shares outstanding during the
 period. The shares owned by a VEBA for the benefit of certain union
 retirees and their surviving spouses and eligible dependents (the
 "Union VEBA") that are subject to transfer restrictions, while
 treated in the balance sheet, similar to treasury stock (i.e., as a
 reduction in Stockholders' equity), are included in the computation
 of the basic shares outstanding in the income statement because such
 shares were irrevocably issued and have full dividend and voting
 rights.

Diluted earnings per share are computed by dividing earnings by the
 weighted average number of diluted common shares outstanding during
 the period.  The weighted average number of diluted shares includes
 the dilutive effect of the non-vested stock and restricted stock
 units granted from dates of grant. The impact of the non-vested
 shares and restricted stock units on the number of dilutive common
 shares is calculated by reducing the total number of non-vested
 shares and restricted stock units (523,968) by the theoretical number
 of shares that could be repurchased under the assumption that the
 hypothetical proceeds of such non-vested shares and restricted stock
 units are the amount of unrecognized compensation expense together
 with any related income tax benefits (324,284). Based on the
 foregoing, a total 199,684 common shares have been added to the
 diluted earnings per share computation.
