FOR IMMEDIATE RELEASE

SGI REPORTS FIRST QUARTER FINANCIAL RESULTS

MOUNTAIN VIEW, Calif. (October 19, 2004)—Silicon Graphics (NYSE: SGI) today announced results for its first fiscal quarter which ended September 24, 2004. Revenue for the first quarter was $175 million, in line with the preliminary results announced October 5, 2004. Gross margin from continuing operations was 35.8% compared with 40.1% in the same quarter one year ago. SGI's first-quarter operating loss from continuing operations was $27 million, compared with an operating loss of $44 million for the first quarter fiscal 2004. The first-quarter net loss was $28 million or $0.11 per share, compared with a net loss of $48 million or $0.23 per share one year ago. GAAP operating expenses from continuing operations for the first fiscal quarter were $89 million compared with $126 million the same quarter one year ago. Excluding a non-cash charge of $3 million, non-GAAP operating expenses were $86 million. This non-cash charge reflects a revised calculation of charges associated with the sublease of the Company's former headquarters campus in fiscal 2004 and was not reflected in the company's preliminary announcement on October 5, 2004. "Despite disappointing results in Q1, we expect improved results in Q2. We have just delivered one of the most powerful computers in the world to NASA and have recently been selected to provide other large configuration Altix systems in the U.S. and abroad,” said Bob Bishop, Chairman and CEO. “In addition, with the launch ofthe new Silicon Graphics Prism system, we now have a full suite of high performance compute, storage and visualization solutions available on the Linux platform." Unrestricted cash, cash equivalents and marketable investments on September 24, 2004 were $125 million as compared with $111 million at the end of the first quarter of fiscal 2004.
