ATI Reports Fourth Quarter and Year-End Financial Results Breakthroughs in Target Markets Set the Stage for 2003

Markham, Ontario - October 2, 2002 - 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 financial results for the fourth quarter and year ended August 31, 2002.

Revenue for the fourth quarter was $239.5 million, down 10 per cent from $266.2 million in the third quarter of fiscal 2002, but was up five per cent from the fourth quarter a year ago. Gross margin was 30.1 per cent, down from 35.0 per cent in the third quarter. Operating expenses, excluding amortisation of intangible assets, increased slightly to $70.1 million from $69.2 million in the previous quarter.

Adjusted net income(1) for the fourth quarter was $2.4 million or $0.01 per share. Net loss on a GAAP basis for the fourth quarter was $32.2 million or $0.14 per share.

"Fiscal 2002 was a year in which ATI made great strides and breakthrough achievements in our target markets," said David Orton, President and Chief Operating Officer, ATI Technologies Inc. "In the past few months we have claimed the technology leadership crown with the introduction of our RADEONTM 9700 family of products. Major OEM design wins, independent evaluations and customer response confirm that ATI has broken through to become the clear choice for speed, performance and value in visual processing products."
(1)Adjusted net income excludes the after-tax effect of gain (loss) on long-term investments (net), amortisation of intangible assets related to the Company's acquisitions, and the deferred tax recovery of future tax liability pertaining to intangible assets acquired. Each of these items has been excluded from adjusted net income as they are not considered to be part of the Company's normalised ongoing operations. While the Company recognises that adjusted net income does not have any standardised 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 the Management's Discussion and Analysis of Interim Financial Results in this news release for the reconciliation between adjusted net income and net income which is determined in accordance with GAAP. All dollar amounts are stated in U.S. dollars unless otherwise noted. All per share amounts are stated on a fully diluted basis unless otherwise noted. ATI's adjusted net income for the year increased to $49.7 million or $0.20 per share from a loss of $16.3 million or $0.07 in 2001. Revenue for fiscal 2002 declined two per cent to $1.02 billion, and gross margins increased 9.6 percentage points to 32.8 per cent, compared to fiscal 2001.

"The transition of our business from a board to a chip model, while it had a constraining effect on our revenues for this fiscal year, has had a direct impact on improving margins and our profitability compared to last year," said Terry Nickerson, Senior Vice President and Chief Financial Officer, ATI Technologies Inc.

"We are delivering new and innovative products across a broad range of the graphics business with the features, performance and price points that address every segment of our market," said K.Y. Ho, Chairman and Chief Executive Officer, ATI Technologies Inc. "Technology leadership and new market successes are enabling ATI to grow the core market, capture marketshare and enter exciting new digital consumer markets."

Outlook
ATI expects the success of the RADEONTM 9700 family of products, as well as contributions from the new integrated graphics processor chip sales, to result in stronger performance in the first quarter of fiscal 2003, relative to the fourth quarter of 2002. The Company is expecting a double-digit percentage increase in revenues for the first quarter, as well as a slight improvement in gross margin. Operating expenses are expected to increase over the fourth quarter of 2002 due to the acquisition of NxtWave, increased product development costs, and the ramp of the new consumer businesses. Based on these factors, ATI is targeting to achieve adjusted net income per share of between $0.03 and $0.05 in the first quarter of fiscal 2003.


Operational Highlights
During the fourth quarter, ATI introduced and started shipping the RADEONTM 9700, RADEONTM 9000 and MOBILITYTM RADEONTM 9000 to become the first graphics company in history to have the top performing products in the desktop market - mainstream and enthusiast - as well as the notebook market, simultaneously. These products captured new design wins with major OEMs, including Apple, Hewlett-Packard, Dell and others. The Company also announced a series of design wins for its new products aimed at the growing integrated, digital TV, and wireless hand-held markets.

Other operational highlights during the quarter:

• ATI announced in August that its RADEONTM 9700-based technology would be rolled out to the workstation market with the introduction of the FIRE GLTM X1.
• ATI's share of the market for notebook discrete chips increased by 4 points to 66 per cent in the second calendar quarter of 2002 according to Mercury Research.
• On the desktop, ATI's share of the discrete market in the second calendar quarter increased by one percentage point to 28 per cent according to Mercury Research.
• ATI began shipping integrated chipset products in volume in the fourth quarter and the Company believes this product represents a significant opportunity for market share over the fiscal year.
• Over 30 models of Pentium 4-based notebooks shipping in the fourth quarter featured ATI RADEONTM chips

ATI achieved breakthroughs beyond the PC market with key design wins for the Company's digital TV and set-top box silicon solutions and wireless hand-held silicon products.

• Key design wins with Scientific-Atlanta and Pace Micro, two of the world's largest manufacturers of set-top boxes, represent an important foothold in the set-top device market.
• ATI's IMAGEON(tm) 100 was selected for Toshiba's e740 PocketPC, one of the most powerful PDAs available.

The launch of Super Mario Sunshine, the latest version of one of the world's most popular games, sparked a new wave of enthusiasm for Nintendo's GAMECUBETM late in the quarter. According to Nintendo, more than 350,000 games were sold in the first 10 days of availability.
Management's Discussion and Analysis of Interim Financial Results
ATI's revenue for the fourth quarter declined 10 per cent to $239.5 million, compared to the third quarter, and was five per cent higher than the fourth quarter of fiscal 2001. Continuing weakness in the world-wide PC market in general and weakness in the notebook business in particular were factors in the decline in revenue compared to the third quarter of the fiscal year. An increase in both desktop and notebook market share accounted for the increase in revenues for the fourth quarter compared to the prior period a year ago, but was somewhat offset by a mix shift from boards to chips.

Gross margin for the fourth quarter was 30.1 per cent of sales, compared to 35.0 per cent in the third quarter, and 29.6 per cent in the same quarter a year earlier. The sequential quarterly decline occurred primarily because of a weaker market for notebooks. The increase in gross margin in the fourth quarter of 2002 compared with the same period a year earlier is generally attributable to a richer chip mix. The Company recognises that its gross margin is too low and is working to bring it into the target range of 32 to 35 per cent.

Operating expenses, excluding amortisation of intangibles, were $70.1 million, or 1.3 per cent higher than the third quarter, and 4.5 per cent higher than the same quarter a year earlier. The sequential quarterly increase in this expense was largely due to increased R&D spending resulting from the acquisition of NxtWave Communications in the fourth quarter, offset by lower administrative and selling and marketing costs. Compared to the same period a year earlier, the increase is largely attributable to higher R&D expense associated with increased costs for new semiconductor technologies as well as the acquisition of NxtWave Communications.

Total operating expenses increased $12.7 million in the fourth quarter to $103.6 million compared to the third quarter and were 17.4 per cent higher than the fourth quarter of fiscal 2001. The increase in the fourth quarter, compared to both the prior quarter and the fourth quarter a year ago, was largely due to the writedown of core technology and goodwill associated with the prior acquisition of the intangible assets of ArtX and Chromatic Research, as well as the increase in R&D and amortisation expense associated with the acquisition of NxtWave Communications.

During the fourth quarter, the Company recorded a net writedown of the value of its long-term investments by an aggregate of $3.1 million to reflect the other than temporary decline in their value.

Adjusted net income(1) for the fourth quarter was $2.4 million or $0.01 per share, compared to adjusted net income of $19.2 million or $0.08 per share for the previous quarter. This decrease in adjusted net income compared to the third quarter was primarily a result of lower revenue and gross margin due to weakness in the notebook market. Adjusted net income in the fourth quarter of 2002 was essentially flat compared to the same period a year ago.


ATI's net loss, on a GAAP basis, in the fourth quarter of fiscal 2002 was $32.2 million or $0.14 per share, compared with a net loss of $2.0 million or $0.01 per share for the third quarter and a net loss of $11.6 million or $0.05 per share for the fourth quarter a year ago. The decline in sequential quarterly net income was largely a result of lower revenues and margins, the writedown of intangible assets related to the acquisitions of ArtX and Chromatic Research, and to a lesser extent the net writedown of the Company's long-term investments.

Inventory levels stood at $175.4 million at the end of the fourth quarter compared with $127.7 million at the end of the third quarter. The increase in inventory occurred, to a large extent, as a result of the Company rapidly ramping up production to support the introduction of new products.

(1)Adjusted net income excludes the after-tax effect of gain (loss) on long-term investments (net), amortisation of intangible assets related to the Company's acquisitions, and the deferred tax recovery of future tax liability pertaining to intangible assets acquired. Each of these items has been excluded from adjusted net income as they are not considered to be part of the Company's normalised ongoing operations. While the Company recognises that adjusted net income does not have any standardised 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.

ATI's financial position remained strong in the fourth quarter. As of August 31, 2002, ATI had working capital of $361.7 million, compared to $370.1 million at the end of the third quarter. The Company's cash position was $236.9 million as of August 31, 2002, compared to $265.7 million at the end of the prior period. The decline was largely due to a cash payment associated with the acquisition of NxtWave Communications as well as increased inventory to support the introduction of new products.

Intangible assets, largely consisting of goodwill associated with the acquisition of ArtX, declined to $209.7 million as of August 31, 2002, from $223.9 million in the third quarter. The decline in intangible assets was largely due to the continued amortisation in intangible assets related to the acquisition of ArtX, as well as the writedown of $10.6 million in core technology and goodwill associated with its acquisition, offset by the intangible assets associated with the acquisition of NxtWave Communications which was recorded during the fourth quarter.

Accounts receivable increased by $2.6 million during the quarter to $164.3 million. Accounts payable increased by $47.4 million in the fourth quarter to $172.1 million. The increase in accounts payable was primarily associated with the inventory buildup of new products.
