1.  COMBINATION AGREEMENT WITH PECHINEY AND ALUSUISSE LONZA GROUP LTD.

    On September 15, 1999, the Company entered into a three-way combination
    agreement with Pechiney and Alusuisse Lonza Group Ltd. (algroup). On April
    13, 2000, in view of objections raised by the European Commission in its
    review of the proposed combination, the three companies announced their
    decision not to proceed with the three-way merger and terminated the
    combination agreement insofar as Pechiney is concerned.

    The combination agreement between the Company and algroup remains in effect
    with respect to their two-way merger and is subject to acceptance by holders
    of at least 67% of algroup shares.

    Included in Deferred charges and other assets at March 31, 2000, was an
    amount of $26 of costs related to the proposed transaction.

    The composite of the applicable statutory corporate income tax rates in
    Canada is 40.3% (40.4% for 1999).

    The difference between income taxes calculated at the composite rate and the
    amounts shown as reported is primarily attributable to investment and other
    allowances.

    In 1999, the difference is primarily attributable to the currency

The Company reports first quarter consolidated net income of US$174 million
compared to US$38 million in the first quarter of 1999 and to US$193 million in
the previous quarter, which included net non-operating gains of US$40 million.
After preference share dividends, net income per common share for the quarter is
78 cents compared to 16 cents a year earlier and to 87 cents (69 cents on an
operating basis) in the fourth quarter of 1999.

Operating earnings per share were almost five times the year-ago level and were
13% higher than the fourth quarter of 1999, continuing the trend of improving
quarterly earnings.

The momentum of improving earnings that began in the second quarter of last year
continued, reflecting increased fabricated sales volumes, improving metal prices
and lower unit costs.

During the quarter, Alcan made further steps in its growth strategy with the
acquisition of Aluminum of Korea (Koralu) in South Korea which, in conjunction
with last year's acquisition of Alcan Taihan Aluminum, will provide the platform
for strong growth in sales and earnings in the Asian region. While the proposed
merger with Pechiney has not proven possible, we look forward to the completion
of the merger with algroup of Switzerland and the additional growth
opportunities that it will provide.

The continuing strong level of Economic Value Added (EVA(R)) and the substantial
year-over-year improvement reflect ongoing strong operating results and the
benefits derived from higher metal prices as well as Alcan's Full Business
Potential (FBP) program.

Sales and operating revenues for the quarter were some 8% above the year-ago
quarter, reflecting both improved shipments and ingot realizations, and were 3%
higher than in the fourth quarter of 1999, reflecting improved realizations on
similar volumes.

Total fabricated product volumes, which include products fabricated from
customer-owned metal, reached a record level of 588 thousand tonnes (kt) in the
quarter, compared to 567 kt in the fourth quarter, and were 12% ahead of
volumes a year earlier. The effect of acquisitions and disposals accounted for
about 2% of the year-over-year increase with the remainder coming from existing
operations.

Average ingot product realizations of US$1,753/tonne were 7% ahead of the
fourth quarter 1999 and 27% ahead of year-ago levels, due mainly to the
improving prices on the London Metal Exchange (LME).

Fabricated product realizations improved from the fourth quarter of 1999
reflecting improving LME prices offset in part by weaker European currencies
against the dollar. The decline compared to the year-ago quarter results
principally form weaker European currencies and changes in product mix due to
the sale of certain downstream businesses.

OPERATING SEGMENT REVIEW

The Company reports selected information by major product sector, viewed on a
stand-alone basis. Transactions between product sectors are conducted on a arm's
length basis and reflect market-related prices. Thus, income from primary metal
operations is mainly profit on metal produced by the Company, whether sold to
third parties or used in the Company's fabricating operations. Income from
fabricated product businesses represents only the fabricating profit on rolled
products and downstream businesses.

First quarter income for the primary metal group showed a strong improvement
over both the year-ago and prior quarters, reflecting higher sales realizations
resulting from increased LME metal prices. Also, the fourth quarter of 1999
included pre-tax rationalization costs of US$9 million. On May 10, 2000, the
company announced the restart of 110,000 tonnes of idled capacity, to be
brought on stream by the end of November. This will result in some 25,000
tonnes of increased primary production in the current year.

In the global fabrication group, operating profits continued to show healthy
year-over-year improvements, although profits were somewhat below those in the
fourth quarter of 1999. The time lag in passing on the increased in metal
prices resulting in a squeeze in fabricating margins. In North America, sales
volume increased some 6% from the year-ago quarter and the fourth quarter of
1999. European shipments were strong with a 15% improvement over a year earlier
and 8% over shipments in the fourth quarter of 1999. In South America, sales
volumes were slightly lower than in the previous quarter but well above year-ago
levels. Demand conditions in Brazil are expected to improve in the remainder of
2000. In Asia, demand continued to be strong.

"Intersector and other items" includes the deferral or realization of profits
on intersector sales of metal. In the first quarter of 2000 and the fourth
quarter of 1999, with rising ingot prices, profits were deferred. For the
first quarter of 1999, as ingot prices decreased, previously deferred profits
on intersector sales were realized. Also included in this

                                       12
   13
category is interest income and, for the fourth quarter of 1999, a pre-tax gain
of US$20 million on the sale of assets, principally property in the UK.

Lower debt levels and the capitalization of interest related to the Alma
project, expected to start up in the fall of 2000, resulted in interest expense
of US$6 million in the first quarter, down from US$22 million in the year-ago
quarter and US$16 million in the fourth quarter of 1999.

The effective income tax rate for the quarter was 37.5% down from 44.7% in the
year-ago quarter due principally to the effect of a non-cash charge of US$9
million included in the prior year's first quarter results relating to the
currency revaluation of the deferred income tax liabilities caused by a
strengthening Canadian dollar. Income taxes for the fourth quarter of 1999
included a favourable adjustment relating to prior periods of US$31 million as
well as a non-cash charge of US$3 million relating to the currency revaluation
of the deferred income tax liability.

In Canada, the improvement in operating net income over the year-ago quarter and
the prior quarter reflects the impact of higher metal prices. The fourth quarter
of 1999 also included a favourable tax adjustment of US$31 million as well as an
overall lower effective tax rate. The first quarter of 2000 includes a loss on
redemption of debt.

In the United States, earnings are down slightly from the fourth quarter of
1999, principally due to the time lag in passing on increases in metal prices to
certain customers. However, earnings are well ahead of those in the first
quarter of 1999, with the improvement primarily reflecting a strengthening in
the primary metal price.

Operating results in South America were in line with those in the prior quarter
and are substantially improved from the first quarter of 1999 when results were
adversely affected by the severe economic recession and currency devaluation in
Brazil.

In Europe, earnings improved in the first quarter due primarily to stronger
metal prices.

Results in the Asia and Pacific region for the quarter were down largely due to
initial expenses related to the Korean acquisition.

LIQUIDITY AND CAPITAL RESOURCES

OPERATING ACTIVITIES

Cash generated from operating activities during the first quarter of 2000 was
$236 million, similar to $230 million in the comparable period of 1999. Although
net income was substantially higher in the current year's quarter, rising metal
prices resulted in an increase in cash required for working capital of $87
million, compared to a reduction in the prior period of $39 million.

                                       13
   14
FINANCING ACTIVITIES

Cash used for financing activities in the first quarter of 2000 was $143 million
compared to $194 million in the comparable period of 1999. The 2000 figure is
primarily due to the redemption of $100 million 9.5% debentures at a price of
104.64%. The 1999 period reflects the expenditure of $219 million to repurchase
for cancellation 8.8 million common shares, offset in part by an increase in
short-term borrowings of $81 million. The debt equity ratio at March 31, 2000,
was 19:81 compared to 21:79 at the end of 1999 and 25:75 a year ago. Total debt
at March 31, 2000, was $1,358 million versus $1,806 million at the same date
last year.

At the end of the first quarter of 2000, the Company had cash and time deposits
of $112 million compared to $623 million a year earlier.

INVESTMENT ACTIVITIES

Capital expenditures during the first quarter of 2000 were $298 million,
compared to $206 million a year earlier. The major project during the quarter
was the Alma, Quebec aluminum smelter, which is due to begin production in
autumn of 2000. During the quarter, the acquisition of Koralu was announced and
this transaction was completed on May 9, 2000. Koralu's operations will be held
through 66%-owned Alcan Taihan Aluminum.

Also during the quarter, the sale of the Company's 54.62% holding in Indian
Aluminium Company, Limited was announced, subject to regulatory clearances. In
the first quarter of 1999, net proceeds from the disposal of business were $191
million, principally the sale of the alumina plant in Aughinish, Ireland.

FINANCIAL INSTRUMENTS - CURRENCY HEDGING FOR ALMA SMELTER

Through a combination of option contracts and forward exchange contracts
totaling $529 million at March 31, 2000, and maturing over various periods in
2000, the Company has hedged its future Canadian dollar commitments for the
construction of the new smelter at Alma, Quebec.

The present hedging position for the Alma project will ensure that the Company
will pay, on average, no more than $0.72 for Can$1.00, and will be able to
benefit, in part, from any future reductions in the value of the Canadian
dollar.

Any gains or losses from these hedging activities, and related costs, will be
included in the capital cost of the new smelter.

THE EURO CURRENCY

Aluminum is a metal traded on the London Metal Exchange (LME) in US dollars. The
great majority of Alcan's sales are at prices based on the LME price and
therefore there is currently no deviation in price between countries in Europe.
The cost of converting the Company's systems to be Euro-compliant is estimated
to be $5 million.

The Company filed a registration statement under the Securities Act of 1933 to
cover Alcan Common Shares that would have been issued to Pechiney shareholders
in connection with the proposed three-way combination of the Company, Pechiney
and algroup. The combination agreement executed by the parties was on file with
the Commission as an annex to the registration statement. As a result of the
termination of the combination agreement with respect to Pechiney (for reasons
set forth in Alcan's Form 8-K filed on March 15, 2000), Alcan has filed an
application to withdraw the registration statement. However, the combination
agreement remains in effect with respect to algroup and, as a material agreement
of Alcan, is being filed as an exhibit to this report.
