(NYSE: WDC) today reported revenue of $533.4 million and a net loss of $3.0 million, or $.02 per share, for its third quarter ended March 30, 2001--including an $11.9 million operating profit in its hard drive business. The net loss includes an extraordinary gain of $371,000 relating to bond redemptions. Unit shipments of approximately 6 million desktop hard drives in the third quarter reflect sequential growth of 3.5 percent from the 5.8 million units shipped in the second fiscal quarter and better than 15 percent growth over the year-ago quarter. The Company's industry-leading 7200 RPM drives accounted for more than 50 percent of third quarter revenue, compared with 42 percent in the second fiscal quarter. The third quarter results included operating losses totaling $15 million for the Company's new business ventures, compared with nearly $20 million in the second fiscal quarter. -MORE-

2 In the year-ago period, the Company reported revenues of $516.6 million and a net loss of $70.7 million, or $.53 per share. The net loss for the year-ago period included non-recurring charges totaling $62.8 million related primarily to the Company's exit of the enterprise hard drive market, and also included a $14.7 million gain on the disposition of certain investment securities. Excluding these items, the Company's net loss for the year-ago period was $22.6 million, or $.17 per share. Matt Massengill, Western Digital president and chief executive officer, stated: "The most noteworthy development in the quarter was the hard drive industry's continued improvement in inventory management and better-than-expected pricing dynamics in the face of the PC industry's most challenging quarter in many years. Against this background, our execution and focus enabled us to achieve profitability and sequential growth in our hard drive business for the second consecutive quarter. As a result of our first-to-market leadership in both 5400 RPM and 7200 RPM-class drives, we optimized our product mix across all of our channels on a worldwide basis." For the nine months ended March 30, 2001, revenue was $1.5 billion and the net loss was $34.8 million, or $.21 per share, including extraordinary gains of $22.2 million. This compares to year-earlier revenues of $1.5 billion and a net loss of $192.2 million, or $1.64 per share, including non-recurring charges of $158.3 million, a $14.7 million gain on disposition of investment securities, and $166.9 million of extraordinary gains relating to bond redemptions.
