                   ATI Reports Third Quarter Financial Results
          Strong customer demand for RADEON-based products drive sales

Markham, Ontario -- June 25, 2003 -- ATI Technologies Inc. (TSX: ATY, NASDAQ:
ATYT), a world leader in the design and manufacture of innovative 3D graphics
and digital media silicon solutions, today announced its financial results for
the third quarter of its 2003 fiscal year, which ended May 31, 2003.

Revenues for the third quarter were $342.1(1) million compared to $318.5 million
in the second quarter of fiscal 2003. Gross margin was 32.9 per cent, rising 4.0
percentage points from 28.9 per cent in the second quarter. Operating expenses,
excluding amortization of intangible assets and other charges(2), increased $9.1
million to $89.4 million compared to the second quarter.

The net income for the third quarter was $12.4 million or $0.05 per share
compared to a net loss of $8.3 million or $0.04 for the second quarter of 2003
and a net loss of $2.0 million or $0.01 per share for the same period a year
ago. Adjusted net income(3) for the third quarter was $17.5 million or $0.07 per
share compared to $9.7 million or $0.04 per share for the previous quarter, and
$19.2 million or $0.08 per share for the same period a year ago.

(1)All dollar amounts are stated in U.S. dollars unless otherwise noted. All per
share amounts are stated on a diluted basis unless otherwise noted.

(2) The Company incurred other charges during the quarter that are not
considered to be part of the Company's normalized operations and in aggregate
represent $2.3 million. These charges arise out of matters relating to the
Ontario Securities Commission investigation. (See Note 7 to the consolidated
financial statements.)

(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 goodwill and 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" in Management's Discussion and
Analysis of Interim Financial Results in this release for the reconciliation
between adjusted net income and net income which is determined in accordance
with GAAP.






                                                                         4 of 28



"Customer demand for our complete line of PC products contributed to our robust
performance this quarter," said K.Y. Ho, Chairman and Chief Executive Officer,
ATI Technologies Inc. "This, coupled with some improvement in the PC market -
particularly notebooks - enabled ATI to deliver solid top-line growth."

"As we look into the fourth quarter and into fiscal 2004, our product line-up
has never been stronger," continued Mr. Ho. "We've recently announced
significant design wins from manufacturers in Asia for our DTV technology, and
the customer demand for richer visual content on smart-phone solutions has
created another growth opportunity for ATI beyond the PC."

"This quarter, we maintained our performance lead in the high-end desktop market
and, in addition, took a significant lead in the performance mainstream and
mainstream markets," said David Orton, President and Chief Operating Officer,
ATI Technologies Inc. "By maintaining ATI's product leadership in our core PC
markets, executing on our product roadmap, and delivering new products in time
for the 'Spring Refresh', we were ready with the right products at the right
time to satisfy growing customer demand."

Outlook
ATI expects revenue in the fourth quarter in the range of $335 - $365 million.
Gross margin for the fourth quarter, as a percentage of revenues, is expected to
improve slightly. Operating expenses, excluding amortization of intangibles and
other charges, for the fourth quarter are expected to be somewhat higher than
the third quarter of this year. As a result of the above, adjusted net income
should improve in the fourth quarter of fiscal 2003 relative to the third
quarter.

OPERATIONAL HIGHLIGHTS
ATI extended its performance leadership in the enthusiast segment and took the
leadership in the performance and mainstream markets with the launch of the
RADEON(TM) 9800, RADEON(TM) 9600 and RADEON(TM) 9200. These products represent
the strongest product line-up the Company has ever seen.




                                                                        5 of 28

     United States, and Hisense.
o    ATI announced a technology development agreement with Nintendo Co., Ltd, in
     which ATI and Nintendo agreed to develop new technologies for use in
     Nintendo products.

Management's Discussion and Analysis of Interim Financial Results

Revenues
ATI's revenues for the third quarter increased 7.4 per cent to $342.1 million
from $318.5 million in the second quarter primarily due to continued broad-based
demand for the Company's products in both the PC OEM and System Integrator or
"white-box" markets.



                                                                        6 of 28




On a year-over-year basis, revenues in the third quarter and the first nine
months were up 28.5 and 25.6 per cent respectively. These increases reflect the
success of ATI's new products, particularly the RADEON(TM) 9800, RADEON(TM) 9700
and RADEON(TM) IGP family of products.

Gross Margin
Gross margin for the third quarter improved to 32.9 per cent of revenues
compared to 28.9 per cent in the second quarter. Increased gross margin right
across the PC product line was largely responsible for this increase, slightly
offset by a quarterly decline in royalty income. Excluding royalty income,
margin improved from 27.9 per cent to 32.4 per cent.

On a year-over-year basis, gross margin as a percentage of revenues for the
third quarter and the first nine months of the year declined from 35.0 per cent
and 33.7 per cent to 32.9 per cent and 29.8 per cent respectively. These
declines were largely a result of a general decline in discrete mobile product
gross margin during the fiscal 2003 periods.

Operating Expenses
Operating Expenses, Excluding Amortization of Intangibles and Other Charges
- ---------------------------------------------------------------------------
Operating expenses, excluding the amortization of intangibles and other charges,
were $89.4 million in the third quarter, up significantly from second quarter
levels of $80.3 million. Of this increase, $1.3 million is associated with the
stronger Canadian dollar, approximately $1.5 million is primarily from
accelerated depreciation on facilities the Company plans to vacate, and
approximately $3.9 million is associated with increased investment in R&D. The
increased selling and marketing expense is directly impacted by just over $1.0
million from variable expense associated with higher sales levels, as well as
$1.7 million in additional advertising to support new product introductions.

On a year-over-year basis, total operating expenses, excluding the amortization
of intangibles and other charges, for the third quarter and the first nine
months of the year increased 29.2 and 19.8 per cent to $89.4 million and $249.3
million respectively. Higher operating expense levels were primarily a result of
increasing investments in R&D, both in headcount and the cost of technology
required to support the increasingly more complex chips; as well as to a lesser
extent, volume-related selling expenses.


                                                                        7 of 28



Other Charges
- -------------
The Company incurred other charges during the quarter that have been excluded
from the Company's adjusted net income calculation. These other charges of $2.3
million arise out of matters relating to the Ontario Securities Commission
investigation. These charges are not considered to be part of the Company's
normalized operations. Please see Note 7 to the consolidated financial
statements.

Total Operating Expenses
- ------------------------
Total operating expenses reflect the operating expenses detailed earlier, as
well as the amortization of intangible assets (see Note 2 to the consolidated
financial statements) and other charges noted above.

Interest and Other Income
- -------------------------
Other income declined $2.0 million sequentially as a result of the write-off of
fixed assets, somewhat offset by the gain on foreign exchange due to the rise of
the Canadian dollar during the quarter.

Net Income
- ----------
Net income in the third quarter of fiscal 2003 was $12.4 million or $0.05 per
share compared to a net loss of $8.3 million or $0.04 per share for the second
quarter of fiscal 2003.

On a year-over-year basis, net income for the third quarter and the first nine
months of the year increased to $12.4 million and $9.1 million respectively.
These increases were a result of higher revenue levels and lower expenses for
goodwill and intangible assets in fiscal 2003 as a result of the adoption of the
accounting policies relating to the treatment of goodwill and intangible assets.
These increases were offset somewhat by greater investment in R&D and increased
selling and marketing expense as well as other charges incurred in the second
quarter and third quarter of fiscal 2003.



                                                                        8 of 28




Adjusted net income(1) for the third quarter was $17.5 million or $0.07 per
share compared to $9.7 million or $0.04 per share for the previous quarter.
Increased revenue and improving gross margin, somewhat offset by increased
operating expenses, was largely responsible for the increase in adjusted net
income.

On a year-over-year basis, adjusted net income per share for the third quarter
and the first nine months of the year declined from $0.08 and $0.19 to $0.07 and
$0.14, respectively, largely as a result of increased operating expenses,
somewhat offset by higher revenue levels.

Liquidity and Financial Resources
ATI's cash flow from operations was $42.6 million in the third quarter of fiscal
2003, reflecting cash generation similar to the previous quarter.

Inventory levels increased slightly to $136.4 million at the end of the third
quarter compared to the second quarter of 2003, where inventory was $131.3
million, but decreased significantly from inventory levels at August 31, 2002 of
$175.3 million. Inventory levels are at an appropriate level to support sales.

Receivables were $205.0 million, up $40.7 million from the end of fiscal 2002
due to strong sales in the third quarter.

As of May 31, 2003, ATI had working capital of $385.7 million, compared to
$361.7 million at August 31, 2002. The Company's cash position, including
short-term investments, grew to a new high of $285.2 million as of quarter end,
compared to $240.9 million in the second quarter. ATI's cash position increased
during the quarter as a result of positive earnings and a pre-payment of $18.0
million recorded as deferred revenue, associated with a development contract.
The Company's cash position as at May 31, 2003 also increased compared to its
levels at August 31, 2002.

(1) 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 goodwill and 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.



                                                                        9 of 28

Intangible assets other than goodwill declined to $10.1 million at the end of
the third quarter of fiscal 2003, from $21.9 million at August 31, 2002. The
decline in these assets was due to continued amortization. During the first
quarter the Company reclassified $2.3 million relating to workforce from
intangible assets to goodwill as a result of the adoption of CICA Handbook
Section 3062.

As discussed previously, beginning in the first quarter of fiscal 2003, the
Company adopted the new accounting policies relating to the treatment of
goodwill and intangible assets (CICA Handbook Section 3062) and therefore is no
longer amortizing these assets. Goodwill, which is associated primarily with the
prior acquisition of ArtX, is currently $190.1 million and will be tested for
impairment on an annual basis. The Company completed the transitional goodwill
impairment assessment during the second quarter of 2003 and has determined no
impairment existed as of September 1, 2002.

Corporate Governance
ATI has appointed Dr. James Fleck, emeritus Professor, Rotman School of
Business, University of Toronto and ex-chairman, Alias Research Inc., as "lead
director" of the Company. The Company has also established a Corporate
Governance and Nominations Committee whose responsibilities include monitoring
and refining ATI's corporate governance policies and procedures on an ongoing
basis. This includes the review and refinement of the Company's corporate
governance policies and procedures to ensure that the Board of Directors of ATI
can fulfill its statutory mandate to supervise the management of the business
and affairs of the Company. In addition to the appointment of Dr. Ronald Chwang
in January 2003, a search is underway for two qualified and independent members
of the Board to expand the size of the Board of Directors to eight.

Assisted by various advisors with expertise in the area of corporate governance,
ATI has enhanced its policies and procedures in the context of the significant
regulatory initiatives in North America that have been adopted to enhance
governance practices of public companies generally. Those initiatives include
the proposed amendments to the guidelines of the Toronto Stock Exchange, the
governance rules proposed by NASDAQ and the various requirements that are coming
into force under the Sarbanes-Oxley Act of 2002.




                                                                       10 of 28


Claims and Proceedings
On May 16th Cirrus Logic, Inc. filed in the United States District Court,
Western District of Texas, a Patent infringement lawsuit against ATI
Technologies Inc. The suit claims infringement of US Patent No. 5,841,418 issued
on November 24, 1998 entitled "Dual displays having independent resolutions and
refresh rates".

The lawsuit seeks injunctive relief and damages in an unspecified amount. ATI
intends to vigorously defend the lawsuit. While Management currently believes
that the amount of ultimate liability, if any, with respect to this action will
not materially affect the financial position, results of operation, or liquidity
of the Company, the ultimate outcome of any litigation is uncertain. Should the
action be successful, there could be a material adverse effect on the Company.

In February, the Company announced that it had reached an agreement for the full
and complete settlement of all remaining claims alleged in the shareholder class
action lawsuits filed in May 2001 in the United States District Court for the
Eastern District of Pennsylvania. The terms of the Stipulation and Agreement of
Settlement, which were subject to final court approval and notice to class
members, included no admission of liability or wrongdoing by the Company or
other defendants. The Court held a fairness hearing on April 25, 2003. There
were no objections raised and the Court approved the settlement. ATI had paid
$8.0 million into court pending final approval, which funds will now be
disbursed in accordance with the Court approved settlement. A portion of this
amount is expected to be paid by ATI's insurer, but has not yet been recognized.




                                                                       11 of 28

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
2002 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 anticipated
growth 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 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, delays in
manufacturing or unfavourable manufacturing yields 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.

and Asia-Pacific.


1.   SIGNIFICANT ACCOUNTING POLICIES


The accompanying unaudited financial statements are prepared in accordance with
Canadian generally accepted accounting principles for interim financial
statements. These financial statements and notes related thereto should be read
in conjunction with the Company's most recent annual consolidated financial
statements, as at and for the year ended August 31, 2002.

These consolidated financial statements follow the same accounting policies and
methods of their application as the most recent annual consolidated financial
statements with the exception of the following:

(a)  CICA Handbook Section 3870, Stock-based Compensation and Other Stock-based
     Payments:

     Effective September 1, 2002, the Company adopted Stock-based Compensation
     and Other Stock-based Payments in CICA Handbook Section 3870, which
     establishes standards for the recognition, measurement and disclosure of
     stock-based compensation and other stock-based payments made in exchange
     for goods and services provided by employees and non-employees. The
     standard requires that a fair value based method of accounting be applied
     to all stock-based payments to non-employees and to employee awards that
     are direct awards of stock, that call for settlement in cash or other
     assets or are stock appreciation rights that call for settlement by the
     issuance of equity instruments. However, the new standard permits the
     Company to continue its existing policy of recording no compensation cost
     on the grant of stock options to employees with the addition of pro forma
     information. The Company has applied the pro forma disclosure provisions of
     the new standard to awards granted on or after September 1, 2002. No
     restatement of prior periods was required as a result of the adoption of
     the new standard. Consideration paid by employees on the exercise of stock
     options is recorded as share capital. See Note 11 for the pro forma
     disclosure as required by this standard.

(b)  CICA Handbook Section 1581, Business Combinations, and Section 3062,
     Goodwill and Other Intangible Assets:

     In September 2001, the CICA issued Handbook Sections 1581 "Business
     Combinations" and 3062 "Goodwill and Other Intangible Assets". The new
     standards mandate the purchase method of accounting for business
     combinations and require that goodwill no longer be amortized but instead
     be tested for impairment at least annually. The standards also specify
     criteria that intangible assets must meet to be recognized and reported
     apart from goodwill. The standards require that the value of the shares
     issued in a business combination be measured using the average share price
     for a reasonable period before and after the date the terms of the
     acquisition are agreed to and announced. Previously, the consummation date
     was used to value the shares issued in a business combination.

     The Company has fully adopted these new standards as of September 1, 2002,
     and has discontinued amortization of all existing goodwill. The Company has
     also reviewed existing intangible assets, including estimates of remaining
     lives, and has reclassified $2.3 million from workforce to goodwill as of
     September 1, 2002 to conform with the new criteria.



                                                                        17 of 28

1.   SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

(b)  CICA Handbook Section 1581, Business Combinations, and Section 3062,
     Goodwill and Other Intangible Assets (continued):

     In connection with Section 3062's transitional goodwill impairment
     evaluation, the Company is required to assess whether goodwill is impaired
     as of September 1, 2002. The Company has completed the transitional
     goodwill impairment assessment during the second quarter of 2003 and has
     determined that no impairment existed as of September 1, 2002.


     Effective September 1, 2002, the Company had unamortized goodwill of $190.1
     million which is no longer being amortized. This change in accounting
     policy is not applied retroactively and the amounts presented for prior
     periods have not been restated for this change. The impact of this change
     is as follows:

meet ongoing operating requirements, the Company has, as a matter of prudence,
commenced the negotiation of a committed syndicated bank credit facility. In the
interim, the Company maintains demand bank credit facilities aggregating $26
million with a single financial institution. There were no borrowings

In the event that 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 for it under this guarantee. The monthly mortgage interest and
principal payment amounts to approximately $0.2 million. The mortgage has a
repayment term of 12 years with a maturity date on November 1, 2014. As of May
31, 2003, the outstanding amount of the mortgage stood at $24.0 million (Cdn.
$32.8 million).

In addition, the Company posted a letter of credit in the amount $2.2 million
(Cdn. $3.0 million) in favour of CVRH and CVRH, in turn, assigned this letter of
credit for 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.


6.   LOSS ON INTEREST RATE SWAP

In fiscal 2001, CVRH entered into an interest rate swap contract to hedge its
exposure to the interest rate risk applicable to its mortgage for the building
facility in Markham, Ontario. This interest rate swap contract closed on
September 10, 2002 resulting in a proportionate loss of $1.4 million to the
Company. The loss is treated as a deferred expense item in the balance sheet and
is charged to the consolidated statements of operations and retained earnings as
a yield adjustment to the interest expense, over the term of the mortgage.

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



(i)  Settlement of class action lawsuits

     On February 7, 2003, the Company announced that it has reached an agreement
     for the full and complete settlement of all remaining claims alleged in the
     shareholder class action lawsuits filed in May 2001 in the United States
     District Court for the Eastern District of Pennsylvania. This litigation
     relates to alleged misrepresentations and omissions made by the Company and
     certain directors and officers during a period preceding its May 2000
     earnings warning. The terms of the Stipulation and Agreement of Settlement,
     which were subject to final court approval and notice to class member,
     included no admission of liability or wrongdoing by the Company or other
     defendants. The Court held a fairness hearing on April 25, 2003. There were
     no objections raised and the Court approved the settlement. ATI had paid $8
     million into court pending final approval, which funds will now be
     disbursed in accordance with the Court approved settlement. A portion of
     this amount is expected to be paid by ATI's insurer, but has not yet been
     recognized.

(ii) OSC Matters

     In January, the Company announced that Staff of the Ontario Securities
     Commission (OSC) had filed a Notice of Hearing and Statement of Allegations
     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 Chief Executive Officer of
     ATI, engaged in insider trading contrary to the Securities Act. A date for
     the hearing has not been fixed. The Board of Directors set up a special
     committee and retained advisors to conduct an independent review of the
     concerns raised by OSC staff.

     So far, the Company has incurred external charges in connection with this
     matter totaling $2.3 million and $5.1 million for the three months and nine
     months ended May 31, 2003 respectively.



                                                                        21 of 28

(iii) Restructuring charge - Europe

      During the second quarter, the Company announced the closure of ATI
      Technologies (Europe) Ltd. ("ATEL"), its subsidiary in Dublin, Ireland.
      The Company has successfully shifted its European business model from
      direct selling to marketing its graphic chip technology to original design
      manufacturers (ODM) and add-in-board (AIB) partners to serve European
      original equipment manufacturers (OEM), the system builders and
      distribution channels. The transition has resulted in the redundancy of
      the operations in Dublin.

      The Company recorded a pre-tax charge of $2.8 million related to the
      closure of ATEL for the second quarter. The following table details the
      components of the charge:

      The following table details the activity through the accrued
      restructuring liability for the quarter ended May 31, 2003:

      Balance at May 31, 2003                                        $ 1,127
      =======================================================================


      The asset impairment is due to the write-down of the building facility in
      Dublin, Ireland to fair value less cost to sell. The building facility,
      which has a fair value of $1.9 million, is included in the capital assets
      for financial statement presentation purposes.

      The Company expects to complete the major components of its exit plan for
      ATEL by July 2003 and to pay out the cash portion of the restructuring
      charge by the end of the fiscal year.

13.  LITIGATION


The Company is subject to a legal proceeding filed in the United States District
Court, Western District of Texas, by Cirrus Logic, Inc. on May 16, 2003
regarding a patent infringement lawsuit against the Company. The suit claims
infringement of US Patent No. 5,841,418 issued on November 24, 1998 entitled
"Dual displays having independent resolutions and refresh rates".

The lawsuit seeks injunctive relief and damages in an unspecified amount. The
Company intends to vigorously defend the lawsuit. While Management currently
believes that the amount of ultimate liability, if any, with respect to this
action will not materially affect the financial position, results of operation,
or liquidity of the Company, the ultimate outcome of any litigation is
uncertain. Should the action be successful, there could be a material adverse
effect on the Company.
