SEAGATE TECHNOLOGY PROVIDES PRELIMINARY

THIRD QUARTER 2004 EARNINGS RESULTS

SCOTTS VALLEY, CA – April 6, 2004 – At the time of Seagate’s (NYSE : STX) mid-quarter update on March 2, 2004, the company indicated its results for the quarter were dependent on normal seasonal demand patterns in March, as well as the continuation of a relatively stable industry environment for the remainder of the quarter. The overall demand for the quarter was modestly weaker than normal seasonal patterns and each major market exhibited characteristics since March 2 that have adversely impacted Seagate’s ability to meet its previously stated earnings estimates. As a result, the company now expects earnings per share of between $0.06 and $0.08 for its fiscal third quarter ended April 2, 2004, excluding the $125 million income tax credit previously disclosed in its 8-K filing of March 16, 2004, which will provide a benefit of approximately $0.25 per share. This is compared to the company’s previously stated earnings per share outlook at the low end of its $0.20—$0.30 range.

Mobile Storage

The most substantial impact to Seagate’s earnings results was the reduction in notebook disc drive shipments, which were affected by two factors. First, the supply imbalance caused by excess purchasing in the December quarter, which the company discussed on March 2, combined with the subsequent slowdown in notebook systems growth and Seagate’s more concentrated customer base, resulted in far fewer shipments than the company anticipated on March 2. Seagate believes that the total available market (TAM) for mobile storage products was more likely 13-13.5 million units compared to approximately 14-14.5 million units that the company had indicated on March 2. As a result, Seagate shipped 1 million mobile storage units during the quarter, representing an approximate 8% share of mobile storage shipments. Given the supply chain circumstances in the mobile market, the supply imbalance may cause further uncertainty into the June quarter.

Personal Storage

The earnings were also impacted by a significant reduction in sales of personal storage products into the distribution channel. This resulted from Seagate’s decision to not reduce prices to stimulate end-of-quarter sales. As a result, the company’s distributors continued to reduce the inventory they were holding. At quarter-end, channel inventory of Seagate products had decreased by about 2 million units, resulting in ending channel inventory of approximately 4 weeks. This reduction in channel inventory should provide for more linear channel shipments going forward.

Additionally, Seagate believes that the TAM for personal storage products was more likely 46-47 million units, compared to the 47-48 million units the company indicated on March 2. During the quarter, Seagate shipped 14.6 million units and regained significant OEM market share, which, when offset by the share loss in the distribution channel, resulted in approximately 31% of overall personal storage shipments.

Enterprise Storage

Seagate’s earnings results were also adversely impacted by the company’s distribution/OEM mix of enterprise storage shipments. While Seagate continues to be encouraged by its strong enterprise market share position, its mix of shipments in the quarter was more heavily weighted toward OEMs than the distribution channel where pricing is currently more favorable.

Seagate believes that the TAM for enterprise storage products was more likely about 5.2 million units, compared to about 5 million units the company indicated on March 2. Seagate shipped 2.5 million units during the quarter, representing approximately 48% of enterprise storage shipments.
