         NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
            (AMOUNTS IN THOUSANDS, EXCEPT PERCENTAGES AND SHARE DATA)


1.  BASIS OF PRESENTATION

        The foregoing unaudited interim consolidated financial statements have
been prepared in accordance with accounting principles generally accepted in the
United States of America for interim financial information and with the
instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the
Securities and Exchange Commission. Accordingly, these financial statements do
not include all of the disclosures required by accounting principles generally
accepted in the United States of America for complete financial statements.
These unaudited interim consolidated financial statements should be read in
conjunction with the audited consolidated financial statements for the year
ended December 31, 2000. In the opinion of management, the unaudited interim
consolidated financial statements furnished herein include all adjustments, all
of which are of a normal recurring nature, necessary for a fair statement of the
results for the interim periods presented.

        The preparation of financial statements in accordance with accounting
principles generally accepted in the United States of America 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 the Company's
(defined below) consolidated financial statements; 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 the Company's
consolidated financial position and results of operations.

        Operating results for the six-month period ended June 30, 2001 are not
necessarily indicative of the results that may be expected for the year ending
December 31, 2001.


2.  OPERATIONS AND PRINCIPLES OF CONSOLIDATION

        Golden Northwest Aluminum, Inc. (the "Company") was incorporated in the
state of Oregon on June 3, 1998 for the purpose of becoming the holding company
of Northwest Aluminum Company, Northwest Aluminum Specialties, Inc.
(collectively "Northwest"), Goldendale Holding Company and its wholly owned
subsidiary, Goldendale Aluminum Company (collectively "Goldendale") and
Northwest Aluminum Technologies, LLC ("Technologies"). The consolidated
financial statements include the accounts of Northwest, Goldendale and
Technologies.

        The operations of the Company consist primarily of the smelting
conversion of alumina to aluminum, processing of aluminum into primary products,
and the sale of those products within one business segment. Since late 2000, the
Company curtailed substantially all of its smelting operations. The Company's
operating subsidiaries' smelting operations were under tolling agreements with
aluminum suppliers through December 1999. In December 1999, Northwest chose not
to continue its tolling arrangement and allowed it to expire. Goldendale's
smelting operations are under a tolling agreement that has been amended and now
expires December 31, 2013. The operations are located in the Pacific Northwest
on the Columbia River. Approximately 72% of the labor force of the Company's



                                       4

         NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
            (AMOUNTS IN THOUSANDS, EXCEPT PERCENTAGES AND SHARE DATA)


subsidiaries is subject to collective bargaining agreements. The agreement with
Goldendale's labor force was due to expire June 1, 2001 and the agreement with
Northwest's labor force was due to expire July 1, 2001. The Company and the
collective bargaining units entered into an agreement to extend the expiration
dates of current labor agreements until September 30, 2001.

        The Company, Goldendale and Technologies report on a calendar year
basis; Northwest reports on a September 30 fiscal year basis. Included in
current liabilities at December 31, 2000 is $4,241 and included in current
assets at June 30, 2001 is $13,668, representing the balance of intercompany
transactions which do not eliminate due to the differing year-ends. All other
significant intercompany accounts and transactions have been eliminated.


3.  EFFECT OF RECENTLY ISSUED ACCOUNTING STANDARDS

        In June 1998, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 133 ("SFAS No. 133"), Accounting for
Derivative Instruments and Hedging Activities. SFAS No. 133 requires companies
to recognize all derivative contracts as either assets or liabilities in the
balance sheet and to measure them at fair value. In June 2000, the Financial
Accounting Standards Board issued Statement of Financial Accounting Standards
No. 138 ("SFAS No. 138"), Accounting for Certain Derivative Instruments and
Certain Hedging Activities. If certain conditions are met, a derivative may be
specifically designated as a hedge, the objective of which is to match the
timing of gain or loss recognition on the hedging derivative with the
recognition of (i) the changes in the fair value of the hedged asset or
liability that are attributable to the hedged risk or (ii) the earnings effect
of the hedged forecasted transaction. For a derivative not designated as a
hedging instrument, the gain or loss is recognized as income in the period of
change. SFAS No. 133 and No. 138 are effective for all fiscal quarters of fiscal
years beginning after June 15, 2000. Effective January 1, 2001, the Company
adopted SFAS No. 133 and 138. The Company reflected the difference between the
fair market value of the derivative instruments and the recorded book value of
the derivative instruments as a cumulative effect type adjustment to accumulated
other comprehensive income. The Company believes that the majority of its
non-trading derivative contracts, power purchase agreements and aluminum
purchase and sale agreements qualify for the normal purchases and sales
exception of SFAS No. 133 and therefore would not be recognized at fair value on
the balance sheet. The Company does however use certain derivative instruments
to limit its exposures to commodity price risk and interest rate risk. The
Company's interest rate swap agreement permits it to limit exposure to interest
rate risk and meets the requirements for hedge accounting under SFAS No. 133.
The Company recorded the changes in the fair value of this contract in
accumulated other comprehensive income on the balance sheet. Aluminum call
options entered into to limit exposure to commodity price risk are not accounted
for as hedging instruments under SFAS No. 133 and as a result, changes in fair
value of these instruments are immediately recognized in income.

        The financial statement impact of recording the SFAS No. 133 transition
adjustment on January 1, 2001 is as follows:

<TABLE>
<S>                                                                         <C>
        Fair value of interest rate swap (liability) ...............        $783
        Increase in accumulated other comprehensive income, net of
            tax of $122.............................................        $228
</TABLE>

         NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
            (AMOUNTS IN THOUSANDS, EXCEPT PERCENTAGES AND SHARE DATA)


Upon initial adoption of the standard, the Company recorded $228, net of tax,
cumulative effect adjustment to accumulated other comprehensive income. This
adjustment relates to the fair value of the interest rate swap contract that
qualified for cash flow hedge accounting prior to the initial adoption of SFAS
No. 133. This amount will reduce interest expense when the related hedged
transaction occurs.

        In June 2001, the Financial Accounting Standards Board approved for
issuance Statement of Financial Accounting Standards No. 141 ("SFAS 141"),
Business Combinations. This standard eliminates the pooling method of accounting
for business combinations initiated after June 30, 2001. In addition, SFAS 141
addresses the accounting for intangible assets and goodwill acquired in a
business combination. This portion of SFAS 141 is effective for business
combinations completed after June 30, 2001. The Company does not expect SFAS 141
to have a material effect on the Company's financial position or results of
operations.

        In June 2001, the Financial Accounting Standards Board approved for
issuance Statement of Financial Accounting Standards No. 142 ("SFAS 142"),
Goodwill and Intangible Assets, which revises the accounting for purchased
goodwill and intangible assets. Under SFAS 142, goodwill and intangible assets
with indefinite lives will no longer be amortized, but will be tested for
impairment annually and also in the event of an impairment indicator. SFAS 142
is effective for fiscal years beginning after December 15, 2001, with early
adoption permitted for companies with fiscal years beginning after March 15,
2001 if their first quarter financial statements have not previously been
issued. The Company is currently analyzing the financial impact that the
adoption of SFAS 142 will have on its consolidated financial statements. The
Company will adopt SFAS 142 in the first quarter of 2002.


4.   INVENTORIES

        Inventories consist of the following:

                                              =======       =======
</TABLE>

        As a result of the continued curtailment of smelting operations and
uncertainties related to the estimated restart date of smelting operations,
adjustment to the valuation of certain raw materials inventory was necessary.
Accordingly, at June 2001, inventory of alumina has been written down to its
estimated net realizable value, and results of operations for 2001 include a
corresponding charge of $1,200.

        In December 1998, the Company issued $150.0 million of 12% first
mortgage notes due on December 15, 2006. Interest is payable semi-annually on
June 15 and December 15, commencing June 15, 1999. Payment of the notes is
guaranteed by all of the Company's subsidiaries. The debt is collateralized by
substantially all of the real property, plant and equipment of the Company's
subsidiaries and by a pledge of all of the issued and outstanding capital stock
of the Company's subsidiaries. On or after December 15, 2002, the notes are
redeemable at the option of the Company at specified redemption prices. There
are no sinking fund requirements. The indenture agreement limits principal
payments on subordinated debt, dividends or shareholder distributions, and
investments in subsidiaries. In connection with the issuance of the notes, each
of the Company's direct and indirect wholly owned subsidiaries has jointly and
severally guaranteed the notes on a full and unconditional basis.

        In December 1998, the Company entered into a $75.0 million bank
revolving credit facility, which matures on December 20, 2003 and is
collateralized by inventory, accounts receivable and related intangibles,
including a security interest in the Company's tolling agreement. Borrowings
under the credit facility bear interest at a floating base rate plus from 0.50%
to 1.00% (7.44% at June 30, 2001) or the LIBOR rate plus from 2.00% to 2.50%
(5.81% at June 30, 2001). The additional margin is dependent upon the
consolidated ratio of earnings before interest, income taxes, depreciation and
amortization to interest expense. The credit facility provides for the payment
of a commitment fee of 0.50% per annum based on the unused portion of the credit
facility. The credit agreement contains restrictive covenants, including a
minimum net worth requirement, a minimum excess availability requirement and
limitations on capital expenditures, dividends, additional indebtedness, mergers
and other business combinations, assets sales, encumbrances, investments and
transactions with affiliates. The Company was in compliance with these covenants
at June 30, 2001. The Administrative Agent for the bank revolving credit
facility increased the "borrowing base reserve" from $15.0 million to $21.0
million during 2001, thus reducing the amount which the Company is eligible to
borrow under the credit agreement.

        Also in December 1998, the Company entered into a subordinated credit
agreement with Norsk Hydro USA, Inc. ("Hydro") pursuant to which $20.0 million
was advanced. The debt bears interest at LIBOR plus two percent (7.23% at June
30, 2001) and is due in December 2005. The debt is secured by a second lien and
a pledge on the collateral securing the first mortgage notes and is guaranteed
by the Company's subsidiaries. Except for the collateral security, the
guarantees by the Company are

subordinate to the indebtedness under the bank revolving credit facility. The
credit agreement provides for additional borrowings of $10.0 million on or prior
to December 31, 2001.

        On January 21, 1999, the Company entered into an interest rate swap
agreement that expires in 2003. The fixed interest rate paid on the swap
agreement is 6.4% and covers $20.0 million of notional principal amount of
floating rate (LIBOR) indebtedness of the Company. Although the Company is
exposed to credit loss on the interest rate swap in the event of nonperformance
by the counterparties, the Company estimates the likelihood of such
nonperformance to be remote. At December 31, 2000, the fair value of the
interest rate swap was approximately $350, and at June 30, 2001 the fair value
of the contract was $693. These amounts reflect the estimated amount that the
Company would pay to terminate the contracts. The interest rate swap agreement
is accounted for as a cash flow hedge. Changes in fair value are recognized in
other comprehensive income.


6.  COMMITMENTS AND CONTINGENCIES

        The Company, in the regular course of business, is involved in
investigations and claims by various regulatory agencies. The Company is also
engaged in various legal proceedings incidental to its normal business
activities. The Company's management does not believe that the ultimate
resolution of these investigations, claims and legal proceedings will have a
material effect on its financial position, results of operations or cash flows.

        During 1999, the Company contracted for the design and construction of a
bath reclaim facility at Goldendale. In connection therewith, a dispute has
arisen over contract change orders to an engineering and construction contract.
The Company has accrued an estimate of the costs to settle the claim in the
amount of $520. If the settlement offer is not accepted, the ultimate cost to
the Company may exceed this accrual.

        As of June 30, 2001, the Company had a liability of approximately $1,895
($1,893 at December 31, 2000), for estimated environmental remediation
activities to be taken on the Company's Goldendale facility. The Company's
estimate of this liability is based on a remediation study conducted by
independent engineering consultants. The total cost of remediation is estimated
at $3,253; however, under a court decree the Company is only responsible for
approximately one-half of the total. The remaining cost is the responsibility of
prior owners. No accrual has been provided for the Northwest facility, as the
Company is unaware of any current condition that would give rise to remedial
action.

        In December 2000, the Company was designated as a potentially
responsible party (PRP) by the U.S. Environmental Protection Agency under the
Comprehensive Environmental Response, Compensation, and Liability Act of 1980,
and by the State of Oregon under applicable state laws with respect to the
Portland Harbor Superfund site in Portland, Oregon. Other PRPs also have been so
designated. The Company, along with other PRPs, is participating in the funding
of a remedial investigation/feasibility study. The Company has been
contractually designated as a de minimus PRP. Management does not anticipate
selection of a remedy for several years and is of the opinion that the Company
will be found to have a de minimus liability, if any, in the outcome of the
matter.

        The Company has entered into various agreements for the purchase of
power, alumina, and aluminum, including agreements with the Bonneville Power
Administration ("BPA") for the purchase of electrical power at fixed rates.
Contracts with BPA expiring on September 30, 2001, were modified in December
2000.

December 31, 2000 are as follows:

</TABLE>

        In October 2000, the Company entered into a new power sales agreement
with BPA that will be effective from October 1, 2001 through September 30, 2006.
The contract will allow the Company to direct available power to either or both
of the operating facilities. Approximately 50% of the Company's power
requirements will be met through the contract. In the summer of 2000, BPA
completed a rate proceeding to determine the base rate under this new power
contract. The base rate adopted by BPA was $23.50 per megawatt-hour. The rate
adopted by BPA also included a "Cost Recovery Adjustment Clause," which allows
BPA to adjust rates under certain defined circumstances. While past BPA rates
also contained a similar adjustment clause, rate adjustments had never been
implemented. Because of dramatically higher market prices for the power BPA
purchases to meet its supply obligations, BPA indicated during the fall and
winter of 2000 that it probably would need to impose a significant surcharge on
rates effective after October 1, 2001.

        In March 2001, BPA proposed a revised and expanded "Cost Recovery
Adjustment Clause" that would give BPA broad discretion to adjust rates every
six months to ensure that it could recover all its costs and repay its
obligations to the U.S. Treasury under almost any circumstances. This revised
"Cost Recovery Adjustment Clause" and the initial rate adjustment were subject
to a new BPA rate proceeding completed in June 2001. The new base rate adopted
by BPA as a result of these proceedings for the period October 1, 2001 through
March 31, 2002 is a maximum of $34.00 per megawatt-hour. The new rates will be
reviewed by the Federal Energy Regulatory Commission ("FERC"). The Company has a
unilateral right to terminate the contract within a specified period after FERC
approves the new rates. The Company anticipates FERC approval by September 2001.
Under the new contract, the Company will not be able to reshape or have BPA
remarket its procurements of power. In addition, the BPA Administrator may have
broad discretion to temporarily or permanently limit or terminate the Company's
purchases of power in circumstances in which the Administrator determines that
the Company is not in compliance with all applicable federal, state and local
laws and regulations. The Company does not expect to receive any cost-based firm
power service directly from BPA after the new contract expires on September 30,
2006.

            (AMOUNTS IN THOUSANDS, EXCEPT PERCENTAGES AND SHARE DATA)


        On April 18, 2001, a Petition for Review under the Northwest Power Act
and Suit for Declaratory and Injunctive Relief under 28 U.S.C. Section 2201(a)
for Violation of 42 U.S.C. Sections 4321, et seq. was filed against BPA in the
United States Court of Appeals for the Ninth Circuit by individuals and the
Utility Reform Project. The plaintiffs seek review of contracts that obligate
BPA to pay industrial customers for not purchasing or not using power the
customer might otherwise purchase from BPA. The Company's modified electrical
power contract with BPA (the "Remarketing Addendum") may be included in this
group of contracts. The plaintiffs also seek to enjoin BPA from performing or
attempting to implement these contracts on the basis that BPA's conduct in
executing these contracts violated the Bonneville Project Act of 1937 and other
statutes. The Company intervened in the case on May 14, 2001. The Company does
not expect the plaintiffs' lawsuit to have any impact on BPA's ability to
perform under the Remarketing Addendum due to the passage of the applicable
statute of limitations, prior favorable court decisions and other factors.
Notwithstanding the foregoing, if BPA were enjoined from performing the
Remarketing Addendum, the Company's business, financial condition and results of
operations would be materially and adversely affected.

        In June 2001, the Company entered into an Amendment to the Block Power
Sales Agreement with BPA. Under the Amendment, for the period October 1, 2001
through March 31, 2002 the Company agreed not to take delivery of the 236
megawatts each hour that the Company is entitled to under the Block Power Sales
Agreement and BPA agreed to purchase those 236 megawatts each hour from the
Company. Additionally, the Company agreed to maintain full-time and part-time
wages and benefits of union and non-union employees that are affected by the
Amendment.

        On May 8, 2001, the Company entered into a Plan and Agreement for
Construction of Resources to Provide Power for Future Operations of Goldendale
Aluminum Company and Northwest Aluminum Company (the "Plan") with Northwest
Energy Development, LLC, a related company ("Northwest Energy"), and the United
Steelworkers of America. Northwest Energy is an affiliate owned by the sole
shareholder of the Company. Under the Plan, the Company will enter into a power
purchase agreement giving it the right, but not the obligation, to purchase up
to 100% of the output from power generation facilities to be developed or owned
by Northwest Energy. The purchase price for the power to be charged to the
Company will be the generating facility's cost of fuel, direct operations and
maintenance, financing, distributions to pay taxes and reasonable general and
administrative expenses. The items included in each of these categories will be
negotiated when the Company enters into power sale agreements with the
generating facilities. The Company's right to purchase power will last for 20
years commencing on commercial operation of the projects. The Company has the
option to use this power in its operations, cause the power to be remarketed at
market prices on the Company's behalf, or do a combination of both. If the
Company causes the power to be remarketed, it generally will be entitled to any
financial benefits in excess of the power's cost. However, these benefits will
be applied to reduce the financing debt of the generating facilities, if needed,
in order to obtain project financing. Reducing the debt would result in reducing
the future cost of power from the facilities, which may result in a lower cost
of power to the Company.

        Under the Plan, the Company designated Northwest Energy as the recipient
of up to $25.0 million in BPA remarketing proceeds to reimburse it for
expenditures incurred or to be incurred in connection with

the development of the power generation facilities. To support loans to
Northwest Energy to finance development of the power generation facilities,
under the Plan Northwest Energy may:

        1)      Request BPA directly or indirectly to guarantee or otherwise
                provide credit support for up to $200.0 million of third party
                debt, with the remarketing proceeds available as collateral or
                for offset; or

        2)      Enter into other arrangements with BPA that have a similar
                economic effect.

        On June 28, 2001, the Company entered into Amendment No. 1 to the
Addendum (the "Amendment"). The Remarketing Addendum, dated December 29, 2000,
was a modification of the Company's existing electrical power contracts with
BPA. Under the Addendum, approximately $285.0 million will be available for
reimbursement of qualified expenditures. Through June 30, 2001 the Company has
requested reimbursement of $32,675 in qualified expenditures. The Amendment
stipulates that a portion of the proceeds from the remarketing of power be
directed and held in an escrow account until October 1, 2006, and that the funds
held in escrow be invested in notes issued by Northwest Energy and other
investments agreed to by BPA and the escrow agent. Upon termination, the funds
held in escrow are to be distributed to BPA.

        In June 2001, the Company received a letter asserting possible breaches
of the indenture for the Company's first mortgage notes from a committee
claiming to represent a majority of the noteholders. The alleged breaches of the
indenture stem from the efforts by Northwest Energy to develop power generation
facilities and the use of remarketing proceeds for this purpose. The Company
does not believe any of these activities breach the indenture. The Company is
discussing these issues with the noteholders' committee.

respectively, were issued and outstanding. The shares were issued in connection
with the acquisition of Goldendale in 1996 and are stated at their per share
fair value when issued of $225. The liquidation preference on the preferred
stock is $225 per share plus accumulated dividends.

        Commencing on January 1, 2002, the preferred shareholders have the
option of receiving additional shares of preferred stock in satisfaction of any
cumulative dividend in arrears that may exist at that time. At December 31, 2000
and June 30, 2001, dividends payable on preferred stock were $16,811 ($127.53
per share) and $16,695 ($141.36 per share), respectively.

        In May 2001, the Company redeemed 13,734.754 shares of preferred stock
for $227.25 per share. The total redemption, including payment of accrued
dividends on redeemed stock, amounted to $5,000. The Company intends to redeem
additional shares of preferred stock on or before April 2002 for the purpose of
funding distributions from the Goldendale Retirement Plan. We may not be able to
redeem these shares. Failure to redeem may result in the illiquidity of the
Retirement Plan.


9.  DERIVATIVE FINANCIAL INSTRUMENTS

        The Company uses derivative financial instruments principally to manage
the risk that changes in interest rates will affect the amount of its future
interest payments and that changes in aluminum prices will affect the cost of
its future purchases. The following is a summary of the Company's risk
management strategies and the effect of these strategies on the consolidated
financial statements.

Commodity Price Risk Management

        The Company holds aluminum call options for the purpose of limiting
exposure to price fluctuations of anticipated aluminum purchases. These options
require the payment of an upfront premium in return for the right to receive the
amount, if any, by which the price at the settlement date exceeds the strike
price. At December 31, 2000 and June 30, 2001, the Company had option contracts
that established a price range for 3,400 to 6,800 metric tons of primary
aluminum per month over a 16-month period beginning January 1, 2001. Although
these options are intended to hedge the risk of market price fluctuations, the
Company elected not to apply hedge accounting. As such, pursuant to SFAS No.
133, the call options are in the "no hedging" designation category. Accordingly,
the Company recognized a non-cash decrease in fair market value of call options
of $1,041 in the period ended June 30, 2001. The fair value of these options at
December 31, 2000 and June 30, 2001 is $2,008 and $1,528, respectively and is
included in other current assets.

Interest Rate Risk Management

        The Company uses an interest rate swap contract to manage the amount of
total debt that is subject to variable interest rates. Under the interest rate
swap contract, the Company agrees to pay amounts equal to a specified fixed-rate
of interest multiplied by a notional principal amount, and to receive amounts in
return equal to a variable rate of interest multiplied by the same notional
principal amount. The notional amount of the contract is not exchanged. No other
cash payments are made unless the contract is



                                       12
<PAGE>   15


                GOLDEN NORTHWEST ALUMINUM, INC. AND SUBSIDIARIES
         NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
            (AMOUNTS IN THOUSANDS, EXCEPT PERCENTAGES AND SHARE DATA)

terminated prior to maturity, in which case the amount paid or received in
settlement is established by agreement at the time of termination and represents
the market quotation, at current rates of interest, of the remaining obligation
to exchange payments under the terms of the contract. The differential between
the variable interest rate and the fixed interest rate, which is to be paid or
received, is recognized in interest expense. Pursuant to SFAS No. 133, the
Company accounts for its interest rate swap contract as a cash flow hedging
instrument. With the adoption of SFAS 133, these swaps resulted in the
recognition of a liability of $693 at June 30, 2001 and a loss in accumulated
other comprehensive income for the period ended June 30, 2001 of $343 (net of
tax of $120).


10.  SUBSEQUENT EVENTS

        On May 1, 2001, Northwest converted $1.8 million of trade receivables
into a note receivable, combining it with an existing note receivable from a
company related by common ownership. The terms of the note were revised to
increase the quarterly payments and extend the repayment terms through November
2011.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

        This section should be read in conjunction with the financial statements
in Part I, Item 1 of this report.


Overview

        Our revenues have historically come from two primary sources:

        1)      Fees received from smelting alumina into aluminum and casting
                that aluminum into primary and value-added aluminum products
                under tolling contracts with Hydro and until December 31, 1999
                with Glencore, and

        2)      The sale of non-tolled value-added aluminum products to other
                customers.

Revenue from fees for the conversion of alumina and processing of aluminum under
tolling arrangements is recognized upon completion of the tolling process. Under
the tolling arrangements, alumina suppliers deliver their alumina to us. The
alumina is converted to aluminum in reduction cells by putting it in liquid form
by dissolving it in an "electrolyte" solution and then passing electric current
through the electrolyte to separate the alumina into its two parts, aluminum and
oxygen. This process is continuous and is nearly instantaneous as the alumina is
dissolved in the electrolyte. The molten aluminum is withdrawn from the cells
and cast or formed into finished products. Revenue from the sale of non-tolled
value-added aluminum products is recognized upon shipment to the customer. Our
revenues include sales of finished products produced by remelting and casting
aluminum material. This remelting activity has provided a significant portion of
our production historically and has allowed us to continue producing finished
aluminum products despite the curtailment of our smelting operations.

        Because our tolling fees are a percentage of prices of aluminum on the
London Metal Exchange, the amount of revenue from tolling activities varies
depending on market aluminum prices, especially LME prices, and gross smelter
production volumes. The tolling fees are based on prior three-month average LME
prices and not current market aluminum prices. Additional revenue for tolled
value-added products is dependent on the volume of value-added production and
the cost of production versus the dollar amount of pricing premiums. The amount
of revenue from non-tolled value-added sales varies depending on market aluminum
prices, demand for our value-added products and the pricing premiums we are able
to realize for these products. Our revenues from non-tolled value-added products
may not be as strongly affected by lower LME prices, as is the case with tolling
fees, because the margin on these products does not vary significantly with
aluminum prices.

        The aluminum industry is highly cyclical, with market prices fluctuating
widely based on global supply and demand factors, most of which are beyond our
control. As shown below, for 2000, the average price per pound of aluminum on
the London Metal Exchange was higher than the average price in 1999 and 1998.
The average three-month LME prices per pound of aluminum over the last six years
were as follows:

</TABLE>


The timing and magnitude of an increase or decrease in aluminum prices is
uncertain. For the six months ended June 30, 2001, the three-month LME price for
aluminum has averaged $.70 per pound. As of June 30, 2001, and more recently at
July 31, 2001, the three-month LME price per pound of aluminum was $0.66 per
pound.

        One of our primary costs is electrical power and prior to 2000, those
costs had been relatively stable. The source of the majority of our power has
been through the Bonneville Power Administration ("BPA"). We have supplemented
the BPA power with purchases of market power during time periods that have
historically had lower cost than our cost through BPA.

        Beginning in the summer of 2000, the market price of electric power
began to increase dramatically because of an extreme shortage of supply and
other factors. As an example, our average cost of power per pound of aluminum
produced was $.16 and $.18 in 1999 and 2000, respectively. The average market
price of power for October 2000 through March 2001 was $245 per megawatt,
equating to $1.95 per pound of aluminum produced. These changes in power prices
made it apparent that we needed to change our strategies to obtain affordable
power long-term.

        While most of our power supply during the fourth quarter of 2000 and the
first three quarters of 2001 were under fixed price contracts with BPA, a
portion was not covered during the late spring 2001 when market power prices
historically have been very low. Because of the dramatic increase in forward
power prices that occurred in 2000, it became uneconomic to purchase power to
meet our open requirements during the spring of 2001. We therefore chose to
reduce our production level to approximately 60% of normal beginning October
2000, "reshape" or sell power that exceeded what we needed for our operations as
a result of our reduced production level and "reshape" or buy power for the open
periods. Our contracts with BPA that expire on September 30, 2001 allow us to
cause BPA to remarket power we do not need for operations and to pay us the
excess proceeds from those sales over the cost we would be required to pay under
the contract. This right is subject to minimum notice provisions and other terms
that make it impractical to make forward sales of greater than one month.

        By the end of December 2000, market prices for electrical power had
further escalated to the point that the financially prudent option was to have
electrical power available to us remarketed by BPA instead of producing aluminum
with it. Late in December, we shut down essentially all remaining smelter
production capacity, leaving only approximately 25,000 metric tons of capacity
on-line at the Goldendale facility and none at Northwest.



                                       17
<PAGE>   20

        To allow us to sell our excess power in forward periods of more than a
month, we entered into a Remarketing Addendum ("Addendum") with BPA, which
allows BPA to remarket the power available to us and to use the resulting
proceeds to reimburse us for defined qualified expenditures. Additionally, we
entered into agreements with the United Steelworkers of America in regard to
employee layoffs, with Norsk Hydro in regard to readjusting our tolling
agreement and with Glencore in regard to readjusting our alumina supply
contract.

        We entered into the Addendum with BPA in December 2000. Under the
Addendum, our operating subsidiaries, Goldendale Aluminum Company and Northwest
Aluminum Company, agreed to curtail smelter production and assist BPA in
remarketing the electric power that they had the right to purchase. BPA agreed
to use the proceeds from the remarketing to reimburse Goldendale Aluminum
Company and Northwest Aluminum Company or their designees for specified
qualified expenditures, including, among others, expenses associated with debt
service and workforce reductions resulting from the curtailment, and
expenditures for the planning, licensing, siting, acquisition and/or
construction of conventional or renewable resources to provide power for future
operations of our smelters. For a given sale of remarketed power, the net
proceeds are equal to the revenue received by BPA on the sale, minus the price
we would have been obligated to pay had we purchased the power, minus a
specified amount retained by BPA, plus any interest costs BPA avoids as a result
of the net proceeds. We estimate that from December 29, 2000 through September
30, 2001, $285.0 million of net proceeds will be available for reimbursement of
qualified expenditures. The Addendum is effective through the earlier of the
date on which all of the net proceeds have been paid by BPA or on September 30,
2010. In June 2001, we entered into an amendment to the Addendum that stipulates
that a portion of the proceeds from the remarketing of power be directed and
held in an escrow account until October 1, 2006, and that the funds held in
escrow be invested in notes issued to Northwest Energy Development, LLC
("Northwest Energy"), a related company, and other investments agreed to by BPA
and the escrow agent. Upon termination, the funds held in escrow are to be
distributed to BPA.

        In October 2000, we entered into a new Block Power Sales Agreement with
BPA that will be effective from October 1, 2001 through September 30, 2006. The
contract will allow us to direct available power to either or both of our
operating facilities. Approximately 50% of our power requirements will be met
through the contract. In the summer of 2000, BPA completed a rate proceeding to
determine the base rate under this new power contract. The base rate adopted by
BPA was $23.50 per megawatt-hour. The rate adopted by BPA also included a "Cost
Recovery Adjustment Clause," which allows BPA to adjust rates under certain
defined circumstances. While past BPA rates also contained a similar adjustment
clause, rate adjustments had never been implemented in the past. Because of
dramatically higher market prices for the power BPA purchases to meet its supply
obligations, BPA indicated during the fall and winter of 2000 that it probably
would need to impose a significant surcharge on rates effective after October 1,
2001.

        In March 2001, BPA proposed a revised and expanded "Cost Recovery
Adjustment Clause" that would give BPA broad discretion to adjust rates every
six months to ensure that it could recover all its costs and repay its
obligations to the U.S. Treasury under almost any circumstances. This revised
"Cost Recovery Adjustment Clause" and the initial rate adjustment were subject
to a new BPA rate proceeding completed in June 2001. The new base rate adopted
by BPA as a result of these proceedings for the period October 1, 2001 through
March 31, 2002 is a maximum of $34.00 per megawatt-hour plus



                                       18
<PAGE>   21

transmission charges of approximately $3.50 per megawatt-hour. The new rates
will be reviewed by the Federal Energy Regulatory Commission ("FERC"). We have a
unilateral right to terminate the contract within a specified period after FERC
approves the new rates. We anticipate FERC approval by September 2001. Under the
new contract, we will not be able to reshape or have BPA remarket our
procurements of power. In addition, the BPA Administrator may have broad
discretion to temporarily or permanently limit or terminate our purchases of
power in circumstances in which the Administrator determines that we are not in
compliance with all applicable federal, state and local laws and regulations.
BPA has indicated we will not receive any cost-based firm power service directly
from BPA after the new contract expires on September 30, 2006.

        In June 2001, at BPA's request we entered into an Amendment to the Block
Power Sales Agreement (the "Amendment") with BPA. Under the Amendment, for the
period October 1, 2001 through March 31, 2002 we agreed not to take delivery of
the 236 megawatts each hour that we are entitled to under the Block Power Sales
Agreement and BPA agreed to purchase those 236 megawatts each hour from us.
These payments will be made directly to us for the sale of power and do not
constitute remarketing proceeds. Additionally, we agreed to maintain full-time
and part-time wages and benefits of union and non-union employees that are
affected by the Amendment. We are in discussions with Hydro and Glencore, Ltd.
("Glencore") about reducing our obligations under our alumina toll and purchase
agreements.


ENERGY DEVELOPMENT

        Because of the instability in power markets and the uncertainty of
future BPA service, our long-term power strategy is now one of self-reliance,
reducing, and ultimately eliminating, our dependence on BPA and other power
providers and becoming a power generator as well as a power consumer. We believe
this strategy will allow us to realize the economic value either of producing
aluminum or selling power and therefore provide us with more stable operating
results.

        The Remarketing Addendum with BPA requires us to dedicate at least $100
million of the remarketing proceeds on the development of new power generation
resources. The development of power generation facilities is not now part of our
core business and requires financing independent of that available under our
current financing arrangements. For these reasons and because the terms of the
indenture governing our first mortgage notes and our bank credit agreement do
not allow us to invest directly in the development of power generation
facilities, our sole shareholder formed Northwest Energy for this purpose.

        On May 8, 2001, we entered into a Plan and Agreement for Construction of
Resources to Provide Power for Future Operations of Goldendale Aluminum Company
and Northwest Aluminum Company (the "Plan") with Northwest Energy and the United
Steelworkers of America. Under the Plan, we will enter into a power purchase
agreement giving us the right, but not the obligation, to purchase up to 100% of
the output from power generation facilities to be developed or owned by
Northwest Energy. Our purchase price for the power will be the generating
facility's cost of fuel, direct operations and maintenance, financing,
distributions to pay taxes and reasonable general and administrative expenses.
The items included in each of these categories will be negotiated when we enter
into power sale



                                       19
<PAGE>   22

agreements with the facilities. Our right to purchase power will last for 20
years commencing on commercial operation of the projects. We will be able to use
this power in our operations, cause the power to be remarketed at market prices
on our behalf, or do a combination of both. If we cause the power to be
remarketed, we generally will be entitled to any financial benefits in excess of
the power's cost. These benefits will be applied to reduce the financing debt of
the facilities, however, if we need to do so to obtain project financing.
Reducing the debt would result in reducing the future cost of power from the
facilities, which would result in a lower cost of power for us. In the short
term, we do not anticipate purchasing all of the output from the facilities. As
a result, the facilities will be able to sell their power on the open market and
use the profits to obtain project financing and reduce project debt.

        Northwest Energy is actively pursuing development of or interests in the
following power projects, which will be subject to the Plan and our power
purchase rights under the Plan.

        1)      Five GE LM6000 turbines and associated equipment to be located
                at the Goldendale smelter facility (the "Turbine Project"), that
                we plan to convert into a more efficient combined cycle
                generating plant by adding heat recovery and steam turbine
                equipment.

        2)      A 520 MW natural gas-fired combined cycle combustion turbine
                project near Clatskanie, Oregon.

        3)      Wind projects to be developed in south central Washington and
                north central Oregon. The first phase is a 24 MW wind turbine
                project in Sherman County, Oregon.

        4)      An interest in a 248 MW natural gas-fired combined cycle
                combustion turbine project near Goldendale, Washington now owned
                by Calpine.

If all of these projects are developed, the resources available to us would
include up to 770 megawatts of base-load, gas-fired, combined cycle combustion
turbine capacity, 225 megawatts of "peaking" capacity and 300 to 600 megawatts
of intermittent wind generation capacity. This capacity would exceed the maximum
requirements of our smelters.

        These power projects are in the early stages of development. We do not
assure you that any of these projects will be completed or that Northwest Energy
will be able to procure any interests in them. Even if these projects are
completed, their completion may be delayed, which will also delay and reduce
anticipated benefits under the Plan. Although we will be able to purchase power
from these facilities at cost, the cost could be too high to economically
produce aluminum. For example, if the price of natural gas increased sharply,
this would result in increased cost to produce electricity at two of the above
listed facilities. If this occurs in conjunction with a decrease in the market
price of power generally, we may be unable to produce aluminum or remarket
power. Finally, depending on the price of power when these facilities are ready
to begin operating, the facilities may not be able to operate profitably.

        Under the Plan, we designated Northwest Energy as the recipient of up to
$25 million in BPA remarketing proceeds to reimburse it for expenditures
incurred or to be incurred in connection with the development of the power
generation facilities. In accordance with the Plan and the amendment to the
Remarketing Addendum that we entered into with BPA in June, 2001, $135 million
of the BPA remarketing proceeds



                                       20
<PAGE>   23

has been directed to, and will be held in, an escrow account until October 1,
2006. Those funds will be invested in notes issued by Northwest Energy and other
investments agreed to by BPA and the escrow agent. Upon termination, the funds
held in escrow are to be distributed to BPA. We believe the $160 million in
remarketing proceeds available to Northwest Energy through loans or direct
payments will be sufficient to fund all of the energy development projects
identified above if the majority of capital is committed sequentially to allow
remarketing proceeds used for earlier financings to be repaid to the escrow and
made available for financings of later projects. We may not, however, be able to
commit the capital sequentially. Based on assumptions we have made about our
operating costs, we believe, but cannot assure you, that the remaining
remarketing proceeds of $125 million not used for the development of power
generation facilities, together with other committed sources of capital, will be
sufficient to fund our operations, debt service and employment obligations
through the next 12 months. By that time, we expect increased remarketing
proceeds to be available for non-energy related qualified expenditures because
of a reduced need for funding of energy projects as a result of the anticipated
refinancing of those projects. We may not be able to refinance the energy
projects on reasonable terms, or at all.

        Northwest Energy has agreed to use the proceeds of loans supported by
BPA credit support for the initial development of the power generation
facilities described above and to use commercially reasonable best efforts to
obtain permanent financing unsupported by BPA credit support at the earliest
opportunity. Northwest Energy may use the proceeds of the loans supported by BPA
credit support for other purposes only with the approval of our board of
directors. We will be eligible to receive liquidated damages from Northwest
Energy if at least 484 megawatts of generation capacity is not available by
October 1, 2006. The liquidated damages would be equal to (1) the percentage by
which energy available to the smelters as of October 1, 2006 is less than 484
megawatts multiplied by (2) the amount of remarketing proceeds paid to Northwest
Energy to support development of the facilities. To secure payment of this
potential obligation of Northwest Energy, we will take a security interest in
the assets of Northwest Energy and its subsidiary project companies. If we
foreclose on the assets, the sales proceeds resulting from the foreclosure may
not cover the amount of liquidated damages. In addition, we have agreed to
release our security interest in a specific project company if requested by a
project lender in connection with project financing through which remarketing
proceeds would be released to another project.

        To consider the Plan, our board of directors designated a special
committee of three independent directors. As required by the indenture governing
our first mortgage notes, the board and special committee engaged a business
valuation firm as financial advisor to the special committee to deliver an
opinion as to the fairness of the Plan to Golden Northwest Aluminum, Inc. from a
financial point of view. The board and special committee also engaged
independent legal counsel to advise the special committee.

        In deciding to approve the Plan, the special committee compared the
likely outcomes of three alternatives: operations under the Plan; a sale or
liquidation of the Company; and a continuation of the curtailment until the
power markets stabilize enough to permit smelter operations to begin again.
Based on this review, we believe the Plan provides the only means for our
stakeholders to receive a return on their investment. We do not believe the
holders of our first mortgage notes would receive their full principal under
either of the alternatives to the Plan. The analysis of these alternatives
required the development of numerous assumptions, any of which could prove to be
incorrect.



                                       21

        Execution of the Plan is subject to many risks and uncertainties. We do
not assure you that Northwest Energy will be successful in developing the
resources discussed above in a timely manner or at all. Remarketing proceeds
used for development of power resources may not be available for the repayment
of debt or for other non-energy-related qualified expenditures.


Other Developments

        On April 10, 2001, Stephen Babson resigned as a member of our board of
directors. Our board is reviewing candidates to fill the resulting vacancy.

        Power prices in the Pacific Northwest continue to be extremely high
compared to historic levels in the region. Beginning May 1, 2001 smelter
production was further reduced to 5% of capacity, allowing for the sale of 25 MW
of BPA supplied electrical power. The sale of this power generated $8.0 million
of net proceeds for the three months ended June 30, 2001. Sale of the power for
the months of July 2001 and August 2001 has been completed with net proceeds of
$1.0 million each month. Sale of power for September 2001 has not been
completed. The remaining smelter production and open market purchases of
aluminum are sufficient to allow us to fulfill our tolling obligations to Hydro.

        As a result of curtailments and uncertainties about operations, we
entered into an agreement with the United Steelworkers of America to extend the
collective bargaining agreements between the United Steelworkers of America and
Northwest Aluminum Company and the United Steelworkers of America and Goldendale
Aluminum Company until September 30, 2001. We plan to negotiate with our unions
both a new collective bargaining agreement and a new agreement for the
curtailment period before the existing agreements expire on September 30, 2001.

        Fleet Capital, as Administrative Agent of our revolving credit facility,
lowered our bank credit rating in April 2001. Also, Fleet Capital increased the
borrowing base reserve to $21.0 million, reducing by $6.0 million the amount
potentially available for borrowing.

        In May 2001, we redeemed 13,734.754 shares of our Preferred Stock for
$227.25 per share plus accrued dividends payable. The total redemption,
including payment of accrued dividends on the redeemed shares, was $5.0 million.
We may not be able to redeem these shares. Failure to redeem may result in the
illiquidity of the Retirement Plan.

        In June 2001, FERC issued an order imposing price caps on the price of
electricity in the western United States. Several factors, including the FERC
order, the reductions in BPA's load of power, price elasticity resulting from
higher electricity prices, the general economic slowdown and cooler than
expected weather in California, have reduced market power prices from over
$250.00 to approximately $60.00 per megawatt-hour. Unfortunately, these prices
are still too high to produce aluminum profitably, but they are low enough to
reduce the anticipated benefits from the power generation facilities Northwest
Energy is developing. If the price of power falls further, prices may be too
high to produce aluminum profitably and too low to generate power profitably.

        In June 2001, we received a letter asserting possible breaches of the
indenture for our first



                                       22
<PAGE>   25

mortgage notes from a committee claiming to represent a majority of the
noteholders. The alleged breaches of the indenture stem from the efforts by
Northwest Energy to develop power generation facilities and the use of
remarketing proceeds for this purpose. We do not believe any of these activities
breach the indenture. We are discussing these issues with the noteholders'
committee.

</TABLE>


THE THREE MONTHS AND SIX MONTHS ENDED JUNE 30, 2000 COMPARED TO THE THREE MONTHS
AND SIX MONTHS ENDED JUNE 30, 2001

        Total revenues decreased from $105.4 million to $40.9 million in the
three months ended June 30, 2000 and June 30, 2001, respectively, a decrease of
$64.5 million, or 61.2%. Total revenues decreased from $233.3 million to $88.7
million in the six months ended June 30, 2000 and June 30, 2001, respectively, a
decrease of $144.6 million, or 62.0%. Revenues were primarily influenced by the
cessation of the Glencore tolling agreement, by the curtailment of significantly
all of our smelter operations to facilitate the opportunity to sell electrical
power into the marketplace and by changes in the market price of aluminum and
power.

        The cessation of the Glencore tolling agreement eliminated 500,000
pounds per day of production billable under tolling arrangements beginning
January 1, 2000. Because of Northwest's September 30



                                       23
<PAGE>   26

year-end, the impact on our consolidated financial statements was reported
beginning April 1, 2000. For the six months ended June 30, 2001 compared to the
six months ended June 30, 2000, tolling revenues decreased $20.7 million due to
the cessation of this agreement. Tolling revenues continued to be earned under
our Hydro tolling contract, decreasing from $48.5 million to $7.9 million for
the three-month periods, and decreasing from $101.5 million to $18.7 million for
the six-month periods, ended June 30, 2000 and June 30, 2001, respectively.
Total revenues from tolling agreements decreased from $48.5 million to $7.9
million for the three-month periods ended June 30, 2000 and June 30, 2001,
respectively, a decrease of $40.6 million, or 83.7%. Tolling revenues decreased
from $122.2 million to $18.7 million for the six-month periods ended June 30,
2000 and June 30, 2001, respectively, a decrease of $103.5 million, or 84.7%.

        Volumes produced under tolling contracts decreased from 86.4 million
pounds to 12.3 million pounds for the three months ended June 30, 2000 and June
30, 2001, respectively, and decreased from 223.0 million pounds to 29.6 million
pounds for the six months ended June 30, 2000 and June 30, 2001, respectively.
The decrease in production volume due to the non-renewal of the Glencore tolling
agreement was 44.5 million pounds, with a related decrease in revenue of $20.7
million. Other than the decrease due to the non-renewal of the Glencore tolling
agreement, the decreases in production level under tolling arrangements was due
to the curtailment of significantly all of our smelter production capacity to
facilitate electrical power remarketing. The production levels at the Goldendale
facility were cut to approximately 15% of normal capacity by early January of
2001, and further cut to approximately 7.5% of normal capacity by early May of
2001, resulting in a decrease in production volume of 74.1 million pounds for
the three-month period and a decrease in production volume of 148.9 million
pounds for the six-month period ended June 30, 2001. These volume changes,
excluding the impact of the cessation of the Glencore tolling agreement, caused
revenues from tolling to decrease by $41.6 million for the three months ended
June 30, 2001 over the same period ended June 30, 2000 and caused revenues from
tolling to decrease by $84.7 million for the six months ended June 30, 2001 over
the same period ended June 30, 2000.

        In addition to the impact of volume changes, increases in the average
tolling charge of $.08 per pound for the three-month periods ended June 30
increased revenues from tolling contracts by $1.0 million. The average tolling
charge for the six-month periods ended June 30 increased by $.06 per pound
causing a $1.9 million increase in revenues from tolling contracts for those
periods. The increases in the average tolling charge were due primarily to
changes in product mix produced under tolling contracts.

        Sales of non-tolled products decreased from $54.8 million to $38.4
million in the three months ended June 30, 2000 and June 30, 2001, respectively,
a decrease of $16.4 million, or 29.9%, and decreased from $107.7 million to
$74.5 million in the six months ended June 30, 2000 and June 30, 2001,
respectively, a decrease of $33.2 million, or 30.8%. The primary factors
affecting revenues from sales of non-tolled products were the softening of the
economy and demand, the curtailment of smelter production capacity at the
Northwest facility, which could only partially be offset by remelt activity, and
a slight increase in average premiums attained for value-added products.

        Shipments of non-tolled aluminum products decreased from 68.2 million
pounds to 46.9 million pounds in the three months ended June 30, 2000 and June
30, 2001, respectively, a decrease of 21.3 million pounds, or 31.2%, with a
corresponding decrease in revenues of $17.1 million. For the six-month



                                       24
<PAGE>   27

periods ended June 30, shipments of non-tolled aluminum products decreased from
137.5 million pounds in 2000 to 95.1 million pounds in 2001, a decrease of 42.4
million pounds, or 30.8%, with a corresponding decrease in revenues of $33.2
million. The curtailment of smelting activity at Northwest reduced the volume of
non-tolled product from 43.6 million pounds to zero for the three-month periods
ended June 30, 2000 and June 30, 2001, respectively, and from 88.6 million
pounds to 23.5 million pounds for the six-month periods ended June 30, 2000 and
June 30, 2001, respectively. These reductions were partially offset with
additional pounds of aluminum made available through our remelt operations.
Aluminum production from remelt operations increased 21.2 million pounds for the
three-month periods ended June 30, and increased 27.6 million pounds for the
six-month periods ended June 30.

        In addition to the impact from changes in volume, a slight increase in
the average selling price provided slight increases in non-tolling revenues for
the three-month and six-month periods ended June 30.

        Other revenues, primarily from the sale of carbon briquettes, decreased
from $3.1 million to $600,000 for the three-month periods, and decreased from
$4.8 million to $900,000 for the six-month periods ended June 30, 2000 and June
30, 2001, respectively.

        Cost of revenues decreased from $96.4 million to $63.5 million in the
three months ended June 30, 2000 and June 30, 2001, respectively, a decrease of
$32.9 million, or 34.1%. Cost of revenues decreased from $215.7 million to
$129.0 million in the six months ended June 30, 2000 and June 30, 2001,
respectively, a decrease of $86.7 million, or 40.2%. As a percentage of
revenues, cost of revenues increased from 91.5% to 155.3% for the three-month
periods and increased from 92.4% to 145.5% for the six-month periods ended June
30, 2000 and 2001, respectively. The primary influences on cost of revenues were
the cessation of the Glencore tolling agreement, a partial curtailment of
production to facilitate the opportunity to have BPA remarket electrical power
in the marketplace, an increase in market aluminum prices and an increase in our
cost of power.

        Smelting production capacity was curtailed and averaged approximately
10% of normal for the three months ended June 30, 2001 and averaged
approximately 19% of normal for the six months ended June 30, 2001. The
production capacity of the Goldendale facility was approximately 15% of its
normal capacity from January 1, 2001 through April 30, 2001, and approximately
7.5% of its normal capacity from May 1, 2001 through June 30, 2001. The
production capacity of the Northwest facility was approximately 50% of its
normal capacity for the first three months of its fiscal year and completely
curtailed for the second three months of its fiscal year. This resulted in a
decrease in production volume of 117.7 million pounds for the three-month
periods ended June 30, with a related decrease in cost of revenues of $47.2
million, and a decrease in production volume of 214.0 million pounds for the
six-month periods ended June 30, with a related decrease in cost of revenues of
$103.1 million.

        Additional aluminum was made available through our remelt operations.
This resulted in an increase of 21.2 million pounds in the amount of purchased
aluminum material used in our operations, with a related cost of $14.8 million
for the three-month period ended June 30, 2001, and 27.6 million pounds, with a
related cost of $19.3 million for the six-month period ended June 30, 2001.

        Gross margin decreased from $9.0 million in the three months ended June
30, 2000 to a gross loss of $22.6 million in the three months ended June 30,
2001, a decrease of $31.6 million, or 351.1%. Gross margin decreased from $17.6
million in the six months ended June 30, 2000 to a gross loss of $40.3 million
in the six months ended June 30, 2001, a decrease of $57.9 million, or 329.0%.
As a percentage of revenues, gross margin fell from 8.5% to (55.3)% for the
three-month periods, and fell from 7.6% to (45.5)% for the six-month periods,
ended June 30, 2000 and 2001, respectively. These decreases in gross margin
resulted primarily from the changes in revenues and the cost of revenues
discussed above.

        Net gains on power sales made available from the curtailment that began
in October 2000 and ended in January 2001 (the "First Curtailment") and the
curtailment that began in May 2001 and will end in September 2001 (the "Third
Curtailment") generated net proceeds of $18.7 million for the three months ended
June 30, 2001 and $50.4 million for the six months ended June 30, 2001. The
First Curtailment made available net gains on power sales of $10.4 million for
the three months ended June 30, 2001 and $42.4 million for the six months ended
June 30, 2001. The Third Curtailment made available net gains on power sales of
$8.0 million for the three months and six months ended June 30, 2001.

        Reimbursement of expenditures of $19.0 million for the three months
ended June 30, 2001, and $32.7 million for the six months ended June 30, 2001
relate to the curtailment that began in January 2001 and will end in September
2001 (the "Second Curtailment").

        Curtailment expenses of $800,000 for the three months ended June 30,
2001 and $8.1 million for the six months ended June 30, 2001 relate to the
Second Curtailment.

        General and administrative expenses increased from $4.4 million to $4.8
million in the three months ended June 30, 2000 and June 30, 2001, respectively,
an increase of 9.1%. General and administrative expenses increased from $8.2
million to $10.1 million for the six months ended June 30, 2000 and June 30,
2001, respectively, an increase of 23.2%. The increases were due primarily to
increases in professional and legal fees. As a percentage of revenues, general
and administrative expenses increased from 4.1% to 11.7% for the related
three-month periods, and increased from 3.5% to 11.4% for the related six-month
periods.

        Interest expense increased slightly from $5.8 million to $5.9 million in
the three months ended June 30, 2000 and June 30, 2001, respectively, an
increase of 1.7%. Interest expense increased slightly from $11.8 million to
$12.0 million in the six months ended June 30, 2000 and June 30, 2001,
respectively, an increase of 1.7%.

        Income tax expense increased from $200,000 to $400,000 in the three
months ended June 30, 2000 and June 30, 2001, respectively. Income tax expense
increased from $1.5 million to $2.5 million for the six months ended June 30,
2000 and June 30, 2001, respectively. These changes were due primarily to an
increase in taxable income of Goldendale, a C corporation, for the three months
and six months ended June 30, 2001 compared to the corresponding periods in
2000.

        Net income was $3.3 million in the three months ended June 30, 2001
compared to a net loss of $1.9 million in the three months ended June 30, 2000
as a result of the foregoing factors. For the six



                                       26
<PAGE>   29

months ended June 30, 2001, net income was $9.6 million, compared to a net loss
of $4.2 million for the six months ended June 30, 2000.


LIQUIDITY AND CAPITAL RESOURCES

        During this period of curtailment, our cash flow and liquidity from
operations will be supplemented by net proceeds on power sales and
reimbursements for "qualified expenditures" from the remarketing proceeds
received by BPA. For the six months ended June 30, 2001, net proceeds on power
sales have totaled $50.4 million. "Qualified expenditures" include
reimbursements for curtailment related employee costs and contract breakage
fees, for capital expenditures and for debt service. Reimbursements of qualified
expenditures from remarketing proceeds through June 30, 2001 totaled $32.7
million. We are dependent upon net proceeds on power sales and distribution of
remarketing proceeds for continued funding of operations.

        Historically, our cash and capital requirements have been satisfied
through cash generated from operating activities and borrowings under our
primary credit facilities.

        Our credit facility with Fleet Capital Corporation is a $75.0 million
senior secured revolving credit facility collateralized by all of the inventory,
accounts receivable and other rights to payment of our subsidiaries.
Availability under the revolving line of credit is controlled by a borrowing
base formula based on eligible receivables and inventory, and a borrowing base
reserve that is presently set at $21.0 million. Based on this formula, we had
net availability of $55.7 million under the revolving line of credit at June 30,
2001, against which we had borrowed $30.5 million. More recently at July 31,
2001, the net availability under the revolving line of credit was $53.4 million,
against which we had borrowed $17.7 million.

        Our liquidity and capital needs relate primarily to payment of principal
and interest on borrowings, capital expenditures, including our facilities
investment program, and distributions to our sole shareholder to pay income
taxes. The first stage of the facilities investment program consisting of an
expansion of the Goldendale casthouse and a 34-cell demonstration of new
cell-line technology has been completed. We have temporarily suspended the
second stage of the facilities investment program because of our recent
curtailments and uncertainties in our long-term supply of competitively priced
electric power. Our liquidity and capital needs also relate to working capital
and other general corporate requirements. Furthermore, we are subject to a
number of contingencies and uncertainties.

        Additionally, the Goldendale preferred stock became redeemable at our
discretion after December 31, 1998. If and when redeemed, we anticipate that the
necessary funds would be drawn from our revolving credit facility with Fleet
Capital. The redemption price for the Goldendale preferred stock at June 30,
2001 was $26.5 million plus any accrued but unpaid dividends, which totaled
$16.7 million at June 30, 2001. In May 2001, we redeemed 13,734.754 shares of
our preferred stock for $227.25 per share to fund distributions from the
Goldendale Retirement Plan, which holds the preferred stock. The total
redemption, including payment of accrued dividends on the redeemed shares was
$5.0 million. We may redeem an additional portion of preferred stock so the
Goldendale Retirement Plan has sufficient liquidity



                                       27
<PAGE>   30

to cover expected retirements and other obligations. We may not be able to
redeem these shares. Failure to redeem may result in the illiquidity of the
Retirement Plan.

        Our statement of cash flows for the periods indicated are summarized
below:

</TABLE>

        Net cash provided by operating activities was $35.7 million for the six
months ended June 30, 2001, and net cash used in operating activities was $5.9
million for the six months ended June 30, 2000. The net cash provided by
operating activities during the six months ended June 30, 2001 was primarily
attributable to cash provided by our net income, as adjusted for non-cash
charges, of $26.9 million. For the six months ended June 30, 2001, our net
income was $9.6 million, depreciation and amortization was $13.8 million and
other non-cash adjustments totaled $3.5 million. Additionally, changes in
working capital provided net cash of $8.8 million, of which $28.0 million
related to receivables and $15.3 million related to inventories, and offsetting
was $28.3 million related to payables, all of which were due to the partial
curtailment of operations.

        The net cash used in operating activities during the six months ended
June 30, 2000 of $5.9 million was attributable to cash provided by our net
income, as adjusted for non-cash charges of $8.3 million. In addition, changes
in working capital used net cash of $14.2 million. The increase in working
capital was primarily due to the transition from the Glencore tolling
arrangement with related impacts on receivables, inventories and payables.

        Net cash used in investing activities was $7.8 million and $14.7 million
in the six months ended June 30, 2001 and June 30, 2000, respectively. Cash used
in investing activities in the six months ended June 30, 2001 was primarily
attributable to capital expenditures of $7.8 million, of which $700,000 related
to the facilities investment program, $2.2 million related to capitalization of
cell-relining costs, and $4.9 million related to routine, ongoing maintenance of
the facilities. Cash used in investing activities in the six months ended June
30, 2000 was primarily attributable to capital expenditures of $15.2 million.

        Net cash used in financing activities was $28.3 million in the six
months ended June 30, 2001, compared to net cash provided by financing
activities of $20.0 million in the six months ended June 30, 2000. Net cash used
in financing activities in the six months ended June 30, 2001 was primarily
attributable to net repayments of $16.7 million under our credit facility,
redemption of preferred stock and payment of the related dividends of $5.0
million, and a distribution to our sole shareholder of $4.4 million for payment
of income taxes. Net cash provided by financing activities in the six months
ended June 30, 2000 was primarily attributable to net borrowings of $17.8
million under our credit facility.



                                       28
<PAGE>   31

        We believe cash flow from curtailed operations, net proceeds on power
sales and the reimbursements from the remarketing proceeds, available borrowings
under our revolving credit facility and under our note purchase agreement with
Hydro, and cash on hand will provide adequate funds for our foreseeable working
capital needs, planned capital expenditures and debt service and other
obligations through the next twelve months.

        Our ability to fund operations, make planned capital expenditures, such
as our facilities investment program, make principal and interest payments on
the notes, and remain in compliance with all of the financial covenants under
our debt agreements will be dependent on our future operating performance and
the success of our power development strategy. Our future operating performance
is dependent on a number of factors, including aluminum prices and power costs,
many of which are beyond our control. These factors include prevailing economic
conditions and financial, competitive, regulatory and other factors affecting
our business and operations, and may be dependent on the availability of
borrowings under our revolving credit facility or other borrowings. We do not
assure you our cash flow from operations, together with other sources of
liquidity, will be adequate to:

-       Make required payments of principal and interest on the notes and our
        other debt;

-       Finance anticipated capital expenditures;

-       Fund working capital requirements; or

-       Fund the possible redemption of all outstanding shares of the Goldendale
        preferred stock.

        If we do not have sufficient available resources to repay any of our
indebtedness when it becomes due and payable, we may need to refinance the
indebtedness. We do not assure you refinancing will be available or available on
reasonable terms.


SEASONALITY AND INFLATION

        Our results of operations can be affected by seasonal factors, such as
substantial increases in the cost of electricity caused by weather related
factors. We do not believe inflation has had a material effect on the combined
financial statements for the periods presented.


EFFECT OF RECENTLY ISSUED ACCOUNTING STANDARDS

        In June 1998, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 133 ("SFAS No. 133"), Accounting for
Derivative Instruments and Hedging Activities. SFAS No. 133 requires companies
to recognize all derivative contracts as either assets or liabilities in the
balance sheet and to measure them at fair value. In June 2000, the Financial
Accounting Standards Board issued Statement of Financial Accounting Standards
No. 138 ("SFAS No. 138"), Accounting for Certain Derivative Instruments and
Certain Hedging Activities. If certain conditions are met, a derivative may be
specifically designated as a hedge, the objective of which is to match the
timing of gain or loss recognition on the hedging derivative with the
recognition of (i) the changes in the fair value of the hedged asset or
liability that are attributable to the hedged risk or (ii) the earnings effect
of the hedged forecasted transaction. For a derivative not designated as a
hedging instrument, the gain or loss is



                                       29
<PAGE>   32

recognized as income in the period of change. SFAS No. 133 and No. 138 are
effective for all fiscal quarters of fiscal years beginning after June 15, 2000.
We reflected the difference between the fair market value of the derivative
instruments and the recorded book value of the derivative instruments as a
cumulative effect type adjustment to "accumulated other comprehensive income".

        We believe that the majority of our non-trading derivative contracts,
power purchase agreements and aluminum purchase and sale agreements qualify for
the normal purchases and sales exception of SFAS No. 133 and therefore would not
be recognized at fair value on the balance sheet. We do, however use certain
derivative instruments to limit our exposures to commodity price risk and
interest rate risk. Our interest rate swap agreement permits us to limit
exposure to interest rate risk and meets the requirements for hedge accounting
under SFAS No. 133. We recorded the changes in the fair value of this contract
in "accumulated other comprehensive income" on the balance sheet. Aluminum call
options entered into to limit exposure to commodity price risk are not accounted
for as hedging instruments under SFAS No. 133 and as a result, changes in fair
value of these instruments are immediately recognized in income.

        The financial statement impact of recording the SFAS No. 133 transition
adjustment on January 1, 2001 is as follows:

<TABLE>
        <S>                                                             <C>
        Fair value of interest rate swap (liability)                    $783,000
        Increase in "accumulated other comprehensive income",
           net of tax of $122,000                                       $228,000
</TABLE>

Upon initial adoption of the standard, we recorded a $228,000, net of tax,
cumulative effect adjustment to "accumulated other comprehensive income". This
adjustment relates to the fair value of the interest rate swap contract that
qualified for cash flow hedge accounting prior to the initial adoption of SFAS
No. 133. This amount will reduce interest expense when the related hedged
transaction occurs.

        In June 2001, the Financial Accounting Standards Board approved for
issuance Statement of Financial Accounting Standards No. 141 ("SFAS 141"),
Business Combinations. This standard eliminates the pooling method of accounting
for business combinations initiated after June 30, 2001. In addition, SFAS 141
addresses the accounting for intangible assets and goodwill acquired in a
business combination. This portion of SFAS 141 is effective for business
combinations completed after June 30, 2001. We do not expect SFAS 141 to have a
material effect on our financial position or results of operations.

        In June 2001, the Financial Accounting Standards Board approved for
issuance Statement of Financial Accounting Standards No. 142 ("SFAS 142"),
Goodwill and Intangible Assets, which revises the accounting for purchased
goodwill and intangible assets. Under SFAS 142, goodwill and intangible assets
with indefinite lives will no longer be amortized, but will be tested for
impairment annually and also in the event of an impairment indicator. SFAS 142
is effective for fiscal years beginning after December 15, 2001, with early
adoption permitted for companies with fiscal years beginning after March 15,
2001 if their first quarter financial statements have not previously been
issued. We are currently analyzing the financial impact that the adoption of
SFAS 142 will have on our consolidated financial statements. We will adopt SFAS
142 in the first quarter of 2002.

FORWARD-LOOKING STATEMENTS

        This report contains statements that constitute "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995. These statements appear in a number of places in this report (see, for
example, "-Overview," "-Energy Development," "-Other Developments," "-Results of
Operations," and "-Liquidity and Capital Resources"). Such statements can be
identified by the use of forward looking terminology such as "believes,"
"expects," "may," "estimates," "will," "should," "plans," or "anticipates" or
comparable terminology, or by discussions of strategy. Readers are cautioned
that any such forward-looking statements are not guarantees of future
performance and involve significant risks and uncertainties, and that actual
results may vary materially from those in the forward-looking statements as a
result of various factors. These factors include the following:

-       Fluctuations in the price of primary aluminum;

-       Fluctuations in the market price of electricity;

-       Fluctuation in the price of natural gas necessary for the production of
        electricity at one or more Northwest Energy projects:

-       Our ability to obtain an affordable and reliable supply of electricity;

-       Our ability to obtain remarketing proceeds from BPA;

-       Servicing our substantial indebtedness;

-       The incurrence of future indebtedness;

-       Redemption of preferred stock and funding of the Goldendale Retirement
        Plan, and the potential consequences if it cannot be funded in a timely
        manner;

-       Restrictions on our ability to operate our business imposed by the terms
        of our indebtedness;

-       The effects of federal and state environmental laws and regulations;

-       The continued viability of the technology used in our smelters;

-       Our ability to operate effectively with and without tolling agreements;

-       Retaining and recruiting key personnel; particularly when both smelters
        have curtailed operations and when continuing severance benefits may be
        reduced or terminated;

-       Changes in labor relations with the unions representing our employees;

-       Possible claims and damages associated with an extended curtailment;



                                       31
<PAGE>   34

-       The timing of the restart of our smelter operations; and

-       Our ability to create or locate cost effective supplies of power.

        Other factors include the effectiveness of management's strategies and
decisions, general economic and business conditions, developments in technology,
new or modified statutory or regulatory requirements, and changing prices and
market conditions. 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.


ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        We manage interest rate risk through the strategic use of fixed and
variable interest rate debt and, to a limited extent, interest rate derivatives.
At June 30, 2001, our derivative instrument consisted of an interest rate swap
agreement that expires in 2003 and effectively fixes our interest rate at 6.4%
on a notional principal amount of $20.0 million on our floating rate long-term
debt. The agreement requires quarterly cash settlements for interest rate
fluctuation outside of the fixed rate.

        In order to manage the risk of market aluminum prices and continue to
service our customer commitments, the strategic use of options on aluminum have
been employed. During the curtailment, we are purchasing 7,500 tons per month of
aluminum that normally would be provided through our Northwest smelter
operation. Options covering from 3,400 to 6,800 tons per month have been
employed to protect against high aluminum prices.

PART II OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

        From time to time, we are involved in various legal proceedings arising
from our normal business activities. We believe these legal proceedings,
individually or in the aggregate, will not have a material adverse effect on our
financial condition, results of operations or cash flows.

        In December 2000, we were designated as a potentially responsible party
(PRP) by the U.S. Environmental Protection Agency under the Comprehensive
Environmental Response, Compensation, and Liability Act of 1980, and by the
State of Oregon under applicable state laws with respect to the Portland Harbor
Superfund site in Portland, Oregon. Other PRPs also were so designated. We,
along with other PRPs, are participating in the funding of a remedial
investigation/feasibility study. We have been contractually designated as a de
minimus PRP. We do not anticipate selection of a remedy for several years and
believe it will be found to have a de minimus liability, if any in the outcome
of the matter.

        On April 18, 2001, a Petition for Review under the Northwest Power Act
and Suit for Declaratory and Injunctive Relief under 28 U.S.C. Section 2201(a)
for Violation of 42 U.S.C. Sections 4321, et seq. was filed against BPA in the
United States Court of Appeals for the Ninth Circuit by individuals and the
Utility Reform Project. The plaintiffs seek review of contracts that obligate
BPA to pay industrial customers for not purchasing or not using power the
customer might otherwise purchase from BPA. Our Remarketing Addendum may be
included in this group of contracts. The plaintiffs also seek to enjoin BPA from
performing or attempting to implement these contracts on the basis that BPA's
conduct in executing these contracts violated the Bonneville Project Act of 1937
and other statutes. We intervened in the case on May 14, 2001. We do not expect
the plaintiffs' lawsuit to have any impact on BPA's ability to perform under the
Remarketing Addendum due to the passage of the applicable statute of
limitations, prior favorable court decisions and other factors. Notwithstanding
the foregoing, if BPA were enjoined from performing the Remarketing Addendum,
our business, financial condition and results of operations would be materially
and adversely affected.
