                ATI Reports Record Revenues in the First Quarter

Markham-- December 19, 2003-- ATI Technologies Inc. (TSX: ATY, NASDAQ: ATYT),
today announced its financial results for the first quarter of fiscal 2004,
ending November 30, 2003. ATI reported record revenues(1) of U.S. $469.7
million, a 40% increase relative to the first quarter of fiscal 2003. Gross
margin showed continued strength at 35.9%. Net income per share for the quarter
was $0.19 compared to $0.03 for the same period last year. Adjusted net
income(2) per share for the quarter was $0.19.


Strong performance in desktop discrete products, based on increasing penetration
of the add-in-board and system integrator (SI) channel led the revenue growth.
Gross margin percentage showed continued strength throughout the quarter based
on ATI's competitive product line-up.


Other highlights included: initiating volume shipments of desktop integrated
graphics processors; sampling the world's first PCI Express video processor in
anticipation of the PC market transition in 2004; and continuing volume
shipments of the IMAGEON multimedia coprocessor.


"Product leadership is enabling ATI to win new customers and penetrate new
markets today," said KY Ho, Chairman and Chief Executive Officer of ATI. "Our
focused execution on delivering our product roadmap is attracting new channel
partners and establishing broader distribution for the future."

Outlook

Based on the strength of the Company's product line, increased SI channel
penetration, and an improving PC market, the Company anticipates that its
results for the second quarter of fiscal 2004 will be stronger than typical
seasonality. ATI expects revenues to be in the range of $430 - $470 million.
Gross margin, as a percentage of revenues, is expected to be in the upper half
of its target range of 32 - 35%. Operating expenses, excluding amortization of
intangible assets and other charges, are expected to be approximately the same
as the first quarter of fiscal 2004.


Management's Discussion and Analysis of Interim Financial Results

The following discussion and analysis should be read in conjunction with the
attached consolidated financial statements and accompanying notes.

Revenues
- --------

ATI's revenues for the first quarter of fiscal 2004 were $469.7 million, a 23%
increase over the fourth quarter of fiscal 2003 and a 40% increase over the
first quarter a year ago.

The increase in revenues compared to the fourth quarter of 2003 was primarily
due to increased shipments of desktop discrete products.

The increase in revenues compared to the first quarter a year ago was the result
of increased sales of ATI's desktop discrete products; greater penetration of
AIB and ODM channels; improved sales of notebook discrete and integrated
processors due to continued growth of the notebook market and a growing
contribution from the consumer business.

Gross Margin
- ------------

Gross margin for the first quarter improved 30 basis points to 35.9% of revenues
compared to the fourth quarter of fiscal 2003 and increased by 8.7 percentage
points over the same period last year. Gross margin grew compared to the same
period last year as a result of improved margins on sales of desktop discrete,
notebook integrated and consumer products. Gross margin in the first quarter of
fiscal 2003 was also negatively affected by a writedown in inventory, as well as
a slower than anticipated transition in the implementation of cost reductions
during the quarter.

Operating Expenses
- ------------------

Operating expenses, excluding the amortization of intangibles and other charges,
were $106.7 million in the first quarter, up from $99.5 million in the fourth
quarter of fiscal 2003, and up from $79.9 million in the first quarter a year
ago. Operating expenses in the fourth quarter of fiscal 2003 included a
non-recurring charge of approximately $6.0 million, consisting of incentive
compensation and other expenses associated with the signing of a development
agreement.

The increase relative to the prior quarter was largely the result of an increase
in expenses related to the Company's recently adopted Restricted Share Unit
(RSU) program. A component of the program was a one-time cash payment to
non-executive employees. Expenses during the first quarter also reflected higher
CAD-related licensing fees, higher advertising and marketing expenditures as
well as incentive-based compensation expenses.

The increase in operating expenses relative to the first quarter of fiscal 2003
was largely due to the factors noted above as well as an increase in staffing
levels to support the Company's growth and the impact of foreign currency
exchange resulting from the rise of the Canadian dollar relative to the U.S.
dollar. A substantial portion of the Company's operating expenses are incurred
in Canadian dollars.

Other Charges
- -------------

The Company incurred other charges during the quarter that have been excluded
from the Company's adjusted net income calculation totaling $0.2 million. Please
see Note 7 to the consolidated financial statements for further disclosure.

Total Operating Expenses
- ------------------------

Total operating expenses reflect the operating expenses detailed earlier, as
well as the amortization of intangible assets and other charges. For further
information on the treatment of the amortization of intangible assets, please
see Note 3 to the consolidated financial statements.

Interest and Other Income (Loss)
- --------------------------------

Interest and other income recorded a loss of $1.8 million in the first quarter
compared to a gain of $0.7 million in the fourth quarter of fiscal 2003, and a
gain of $0.5 million for the same period a year ago, due to the writedown of
fixed assets.








ATI Reports Record Revenues in the First Quarter                       6 of 25



Net Income
- ----------

Net income in the first quarter of fiscal 2004 was $47.4 million or $0.19 per
share compared to net income of $22.3 million or $0.09 per share for the fourth
quarter of fiscal 2003 and net income of $7.3 million or $0.03 per share for the
first quarter last year.

The increase in net income sequentially was primarily the result of higher
revenues and gross margin. The $40.1 million increase in net income compared to
the same period a year ago was primarily due to higher revenues and gross
margin, partly offset by higher total operating expenses.

Adjusted net income(3) for the first quarter was $49.0 million or $0.19 per
share compared to $29.0 million or $0.12 per share for the previous quarter and
$9.3 million or $0.04 per share recorded in the same period last year. Increased
revenues and associated gross margin, partly offset by higher operating
expenses, were largely responsible for the increase in adjusted net income
relative to both comparative periods.

Liquidity and Financial Resources

Inventory levels increased to $224.6 million at the end of the first quarter of
2004 from $176.5 million at the end of the fourth quarter of fiscal 2003. Higher
inventory levels generally reflect the higher current level of sales.

Receivables were $269.0 million at the end of the first quarter, up $34.4
million from the end of fiscal 2004, consistent with the increase in sales in
the quarter.


- ------------------------

(3) Adjusted net income excludes the after-tax effect of gain on investments,
after-tax effect of other charges described in Note 7 to the consolidated
financial statements, amortization of intangible assets related to the Company's
acquisitions, and deferred tax recovery of future tax liability pertaining to
intangible assets acquired, related to the Company's acquisitions. Each of these
items has been excluded from adjusted net income as they are not considered to
be part of the Company's normalized operations. While the Company recognizes
that adjusted net income does not have any standardized meaning described by
generally accepted accounting principles, or GAAP, and that its adjusted net
income calculation cannot be used as a comparison to other companies' financial
performance, ATI believes that its adjusted net income more appropriately
reflects the Company's operating performance. Please see the table titled
"Adjusted Net Income - Reconciliation" at the end of this release for the
reconciliation between adjusted net income and net income which is determined in
accordance with GAAP.

As of November 30, 2003, ATI had working capital of $478.9 million, compared to
$430.3 million at August 31, 2003. ATI's cash flow from operations was $37.3
million in the first quarter of fiscal 2004. The Company's cash position,
including short-term investments, was $380.0 million as of quarter-end, compared
to $350.7 million at the end of fiscal 2003. ATI's cash position increased as a
result of an increase in earnings, offset by purchases of shares related to the
recently adopted RSU program.

Intangible assets other than goodwill increased slightly to $10.1 million at the
end of the first quarter of fiscal 2004, from $8.8 million at August 31, 2003.
The increase in these assets was due to the acquisition of AMI Technologies
Inc., of which $2.9 million of the purchase price was allocated to intangible
assets.

Adjusted Net Income  - Reconciliation
The table below presents adjusted net income and adjusted net income per share,
which excludes the after-tax effect of gain on investments, after-tax effect of
other charges, amortization of intangible assets related to the Company's
acquisitions, and deferred tax recovery of future tax liability pertaining to
intangible assets acquired, related to the Company's acquisitions.

Forward-looking Statements and Uncertainties

Certain statements in this release constitute "forward-looking statements." When
used in this release, words such as "plans," "intends," "anticipates," "should,"
"estimates," "expects," "believes," "indicates," "targeting," "suggests," and
similar expressions are intended to identify forward-looking statements.
Forward-looking statements are based on current expectations and entail various
risks and uncertainties that are outlined in this release and in the Company's
2003 Annual Report and 2002 Annual Information Form. As a result of these risks
and uncertainties, the Company's operating results and common share price may be
subject to significant volatility, particularly on a quarterly basis. For
example, the markets for the Company's products are characterized by changing
market conditions, frequent new product introductions, seasonal and variable
demand and rapid technology changes. Other factors that could cause the
Company's results to vary include, but are not limited to, lack of growth or
declines in the demand for PCs, gaming consoles and consumer electronic devices
in which the Company's products are incorporated, reductions in the Company's
average selling prices for its products and reduced gross margins due to
competitive pressures and other factors, the introduction of new products by the
Company's competitors which render the Company's products non-competitive,
delays encountered by the Company in developing new products or enhancements,
including integrated graphics and core logic components, in the time frame
required by its customers or lack of acceptance by customers of these products,
delays in manufacturing, unfavourable manufacturing yields or capacity
shortfalls experienced by the Company's independent foundries, unexpected
variances in material costs, including silicon wafer, memory and printed circuit
boards, and constraints on the supply of components utilized in the Company's
products and in the PC industry generally. These risks and uncertainties could
cause or contribute to actual results that are materially different from those
anticipated or experienced in the past. Additional information concerning
factors that could cause the Company's financial results to fluctuate is
contained in the Company's filings with Canadian and U.S. securities regulatory
authorities. ATI disclaims any obligation or intention to update or revise any
forward-looking statement, whether as a result of new information, future events
or otherwise.

ATI TECHNOLOGIES INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
November 30, 2003
(Unaudited)


The principal business activities of ATI Technologies Inc. (the "Company") are
the design, manufacture and sale of innovative 3D graphics and digital media
silicon solutions. The Company markets its products to original equipment
manufacturers, system builders, distributors and retailers primarily in North
America, Europe and the Asia-Pacific region.


1. SIGNIFICANT ACCOUNTING POLICIES

The accompanying unaudited financial statements are prepared in accordance with
Canadian generally accepted accounting principles for interim financial
statements. Certain information and note disclosures normally included in the
annual financial statements prepared in accordance with generally accepted
accounting principles have been condensed to include only the notes related to
elements which have significantly changed in the interim period. As a result,
these interim consolidated financial statements do not contain all disclosures
required to be included in the annual financial statements and should be read in
conjunction with the most recent audited annual consolidated financial
statements and notes thereto for the year ended August 31, 2003.

The financial information included herein reflects all adjustments (consisting
only of normal recurring adjustments), which, in the opinion of management, are
necessary for a fair presentation of the results for the interim periods
presented. The results of operations for the three months ended November 30,
2003 are not necessarily indicative of the results to be expected for the full
year.

During fiscal 2003, the Company reviewed its revenue recognition accounting
policy as it is applied to the shipment of products to its customers. Following
this review, the Company corrected its revenue recognition accounting policy by
revising the timing of when revenue is recognized to more clearly identify the
point in the shipping process when the risks and rewards of ownership have been
transferred to the customer. This change, and the related income tax effect,
have been applied retroactively. The financial statements presented for
comparative purposes have been restated to give effect to this change.








                                                                      13 of 25



The impact of this change on the first quarter of fiscal 2003 is as follows:

          joint venture in which the Company has a 50 per cent ownership
          interest, entered into a mortgage agreement with a lender to finance

6.   GUARANTEE

The Company and other owners of CVRH have jointly and severally provided a

CVRH is unable to meet the underlying mortgage payment to the lender, the
Company and other owners of CVRH will be jointly and severally responsible under
this guarantee. The monthly mortgage interest and principal payment amounts to
approximately $0.3 million. The mortgage has a repayment term of 12 years with a
maturity date on November 1, 2014. As of November 30, 2003, the outstanding

to the exclusive benefit of the lender as additional security of the mortgage.
The letter of credit has a term of 5 years and will expire on November 5, 2007.
In the event of a lease default by the Company, the proceeds of the letter of
credit will be paid to the lender.








                                                                      16 of 25

      ----------------------------------------------------------------------



     (i)  Regulatory Matters

          In January 2003, the Company announced that Staff of the Ontario
          Securities Commission ("OSC") had filed a Notice of Hearing and
          Statement of Allegations ("Notice") in relation to ATI and others. The
          Notice alleged that ATI failed to disclose information concerning the
          shortfall in revenues and earnings that occurred in the third quarter
          of fiscal 2000, as required by the listing rules of the Toronto Stock
          Exchange. The Notice also alleged that ATI made a misleading statement
          to Staff of the Commission in August 2000 regarding the events leading
          up to the disclosure on May 24, 2000 of the shortfall. Seven
          individuals are also named in the Notice. The Notice alleged that six
          of these individuals, including K.Y. Ho, the Chairman and Chief
          Executive Officer of the Company, engaged in insider trading contrary
          to the Securities Act. The hearing has been set for February - March
          2004. The Board of Directors set up a special committee and retained
          advisors to conduct an independent review of the concerns raised by
          OSC staff.

          The Company has incurred external charges in connection with this
          matter totaling $0.7 million during the three months ended November
          30, 2003 (2003 - nil).








                                                                      17 of 25

         (a)  During the second quarter of fiscal 2003, the Company announced
              the closure of ATI Technologies (Europe) Limited ("ATEL"), its
              subsidiary in Dublin, Ireland and recorded a pre-tax charge of
              $2.8 million. The charge included a $1.4 million write-down of the
              building facility in Dublin, Ireland to fair value less cost to
              sell. The Company completed the major components of the exit plan
              for ATEL in July 2003.

              During the current quarter, the Company was able to sell the
              building facility at a higher price resulting in a recovery of
              $0.5 million from the restructuring charge. The Company also paid
              out the remaining cash portion of the restructuring charge of $0.5
              million during the quarter.

         (b)  During the fourth quarter of fiscal 2003, the Company decided to
              discontinue the operations of ATI Research GmbH, its FireGL
              product division located in Starnberg, Germany, in order to
              consolidate its research and development activities. As a result,
              the Company recorded a pre-tax charge of $3.8 million for the
              quarter pertaining to the closure of ATI Research GmbH.

              During the current quarter, the Company made cash payments of
              $2.7 million relating to the pre-tax charge set-up in the fourth
              quarter of fiscal 2003. The Company expects to complete the major
              components of its exit plan for ATI Research GmbH by December
              2003.








                                                                      18 of 25

11.  STOCK-BASED COMPENSATION

     (i)  Stock options

          For stock options granted to employees after September 1, 2002, had
          the Company determined compensation costs based on the "fair value" of
          the stock options at grant dates consistent with the method prescribed
          under CICA Handbook Section 3870, the Company's net income per share
          would have been reported as the pro forma amounts indicated below:

11. STOCK-BASED COMPENSATION (CONTINUED)

     (i)  Stock options (continued)

          For purposes of pro forma disclosures, the estimated fair value of the
          options is amortized to expense over the options' vesting period.

     (ii) Restricted share units

          During the current quarter, the Company announced that it adopted a
          plan to grant restricted share units ("RSUs") as part of its overall
          stock-based compensation plan. Under this plan, certain employees will
          receive an award in the form of an RSU. Each RSU entitles the holder
          to receive one common share on the vesting date of the RSUs. The RSUs
          vest on each anniversary of the grant in equal one-third instalments
          over a vesting period of three years. Stock-based compensation
          representing the underlying value of $14.17 per common share of the
          Company at the date of grant of the RSUs is being recognized evenly
          over the three-year vesting period. On the vesting dates, the RSUs are
          settled by the delivery of common shares of the Company to the
          participants except for the participants residing outside of North
          America who will receive cash equivalent market value of the shares.
          Grants of RSUs to participants residing outside of North America are
          accounted for using variable plan accounting whereby the value of the
          RSUs and their related amortization are adjusted based on the
          underlying value of the Company's common shares at the end of each
          fiscal quarter. As at November 30, 2003, there were 1,556,239 RSUs
          awarded and outstanding of which none were vested.

          The issuance of RSUs replaced the annual grant of options for the 2003
          calendar year. In addition, a one-time cash payment of $7.8 million
          was also awarded to the non-executive employees who were eligible for
          the RSU plan. This amount was expensed in the current quarter. The
          total expenses by functional areas incurred for the three months ended
          November 30, 2003 pertaining to the cash payment and amortization of
          RSUs are as follows:

          ------------------------------------------------------





         During the quarter, the Company advanced $22.1 million to the trustee
         of the RSU plan to enable the trustee to purchase the Company's common
         shares in the open market. These shares are being held by the trustee
         in order to deliver such shares to the participants on the vesting
         dates of the RSUs.

          exercise price denominated in a currency other than the currency of
          the primary economic environment of either the employer or the
          employee, should be accounted for under the variable accounting

     (ii) Under U.S. GAAP, the intrinsic value of the stock options issued under

          increase in the Company's stock price between the grant date and the
          date on which all the conditions of the specified business arrangement
          were determined to have been met. The compensation expense is
