Montreal, Quebec, November 1, 2004

CGI Group Inc. (NYSE: GIB; TSX: GIB.A) (CGI), a leading provider of end-to-end information technology and business processing services, today reported preliminary results for its fiscal 2004 fourth quarter ended September 30, 2004. All figures are in Canadian dollars unless otherwise indicated.

Revenue for the fourth quarter ended September 30, 2004 increased 39.9% to $959.2 million, from $685.7 million in the same quarter last year, and was up 10.6% sequentially over third quarter revenue of $867.1 million. The increase reflects the acquisition of American Management Systems ("AMS") in May 2004 and new business. Sequentially, the currency exchange rate, mainly between the Canadian and US dollars, had a negative impact of $14.2 million on revenue for the quarter.

Net earnings from continuing operations in the fourth quarter increased 12.6% to $58.5 million from $51.9 million in the third quarter, while the net earnings margin for continuing operations was 6.1%, compared with 6.0% in the third quarter. The net earnings margin increased in the fourth quarter despite a $3.6 million impact due to seasonal factors. Compared with the previous year, net earnings from continuing operations in the fourth quarter increased 22.1% from $47.9 million.

Basic and diluted earnings per share from continuing operations were $0.13 in the fourth quarter, compared with $0.12 in last year's fourth quarter and $0.12 in the third quarter.

For the full year, revenue increased 20.8% to $3.24 billion, from $2.68 billion in fiscal 2003. Net income from continuing operations increased 20.7% to $210.8 million or $0.50 per share, from $174.7 million or $0.44 per share in fiscal 2003. Net income including discontinued operations increased 23.8% to $219.6 million or $0.52 per share, from $177.4 million or $0.45 per share in 2003. The currency exchange rate had a year-over-year negative impact of $60.1 million on revenue. The backlog of signed contracts at September 30, 2004 was $13.0 billion and the pipeline of proposals, being reviewed by potential clients, now totals $7 billion, up from $5 billion previously.

"We are pleased to have achieved such strong year-over-year and sequential revenue and earnings growth in the fourth quarter," said Serge Godin, Chairman and CEO, CGI. "We are seeing positive trends, including the impact of the successful integration of AMS on our earnings margin, increasing profitability in our US and European operations, and strengthening demand in our markets."

Guidance
Based on current market conditions and the opportunities we see in our markets, we provide the following guidance for fiscal 2005. We expect to achieve growth in revenue of 20% to 28% and growth in net earnings of 25% to 35%, after giving retroactive effect to the expensing of stock options. This will represent revenue between $3.90 billion and $4.15 billion and earnings per share between $0.52 and $0.56, after the expensing of stock options. Beginning in the first quarter of fiscal 2005, in accordance with Canadian generally accepted accounting principles (GAAP), CGI will begin expensing stock options. For comparison purposes with US peers, and since they are not yet required to expense stock options under US GAAP, CGI discloses the expected effect of stock options expensing on its earnings per share, which is expected to be $0.05 in fiscal 2005.
