Research In Motion Reports First Quarter Results

Waterloo, ON - Research In Motion Limited ("RIM") (Nasdaq: RIMM, TSX: RIM), a world leader in the mobile communications market, today reported first quarter results for the three months ended June 1, 2002 (all figures in U.S. dollars and Canadian GAAP).

Revenue for the first quarter of fiscal 2003 was $71.6 million, an increase of 8% from $66.1 million in the previous quarter. The revenue breakdown for the quarter was 39% for handhelds, 41% for service, 13% for software licences and development, and 7% for OEM radios and other revenue. The total number of BlackBerry subscribers increased by approximately 34,000 to 355,000 as at June 1, 2002.

"I am pleased to report that RIM has once again achieved its quarterly performance targets as well as the strategic milestones that drive our continued success and leadership in the wireless enterprise sector," said Jim Balsillie, Chairman and Co-CEO at Research In Motion. "Together with our partners, we are delivering the 2.5G devices, services, tools, applications and infrastructure to provide broadly adaptable solutions that solve real customer problems and offer substantial return on investment."

Gross margin for the quarter was 43.5%, as compared to 42.1% in the prior quarter. The increase was primarily due to increased margins on handhelds and other hardware products and changes in the revenue mix, with service revenue comprising a higher percentage of total revenue for the quarter as compared to the prior quarter.

The net loss for the quarter was $10.8 million or $0.14 per share compared to a net loss of $8.6 million or $0.11 per share in the prior quarter.

Gross research and development expenditures were $16.2 million or 23% of revenue compared to $14.8 million or 22% of revenue in the prior quarter. Continued focus on development of next-generation handhelds for Europe, Asia and North America, together with ongoing development of the BlackBerry platform, has continued to drive the increase in research and development expenses. Net research and development expenditures were $12.6 million for the quarter as compared to $12.0 million last quarter.

Selling, marketing and administration expenses were $28.0 million or 39% of revenue, compared to $26.6 million or 40% of revenue in the prior quarter. The results for the prior quarter included a $3.9 million reduction of selling, marketing and administration expenses. Excluding the effect of this recovery in the prior quarter, adjusted selling, marketing and administration expenses were $30.5 million.

Cash, cash equivalents and marketable securities were $616.0 million as at June 1, 2002, compared to $644.6 million at the end of the previous quarter, for a net decrease of $28.6 million quarter over quarter. Cash inflows from operating activities were $6.1 million, offset by investments in capital and intangible assets of $24.7 million and disbursements of $10.2 million from investing activities, the majority of which was used to repurchase 685,000 common shares pursuant to the Company's previously announced Common Share Repurchase program.
