Exhibit 99.1 ADE Corporation Reports Revenue Growth and Continued Profitability in Second Quarter; Sequential Growth in New Orders Continues WESTWOOD, Mass.--(BUSINESS WIRE)--Dec. 2, 2003--ADE Corporation (Nasdaq: ADEX), a leading supplier of production metrology and inspection systems for the semiconductor wafer, semiconductor device, magnetic storage and optics manufacturing industries, today reported its financial results for the second quarter ended October 31, 2003. ADE reported revenues of $20.2 million in the second quarter of fiscal 2004 compared with $19.1 million for the first quarter of fiscal 2004 and $18.1 million for the second quarter of fiscal 2003. ADE's net income for the second quarter was $1.7 million, or $0.12 per diluted share. This figure includes a tax refund of approximately $300,000. This compares with net income of $1.8 million, or $0.13 per diluted share, in the first quarter of fiscal 2004 and a net loss of $2.4 million, or $0.18 per share, in the second quarter of fiscal 2003. First quarter fiscal 2004 net income included approximately $400,000 in severance charges as well as $1.7 million of income from the gain of the sale of a portion of the Company's 50% ownership in Japan ADE, Ltd. (JAL) to its joint venture partner, Kanematsu Electronics, Ltd. Backlog increased 15% to $31.5 million on October 31, 2003 from $27.4 million on July 31, 2003. Cash and cash equivalents totaled $34.9 million at October 31, 2003. This compares with $21.5 million in cash and cash equivalents at fiscal 2003 ended April 30, 2003. "ADE's increased revenues, bookings and backlog demonstrate our success in capitalizing on the upturn in the semiconductor industry and executing on key elements of our growth strategy," said Dr. Chris L. Koliopoulos, ADE's president and chief executive officer. "Higher utilization has triggered capacity expansion by both wafer and device manufacturers as they ramp up 300mm production as well as advanced 200mm for 130nm and 90nm processes. Once again, ADE received the largest order in its history, setting a new high mark that was previously set in the quarter before. Wafer and device manufacturers continue to turn to ADE for advanced metrology and inspection equipment that meets their stringent requirements. As a result, we continue to experience strong quote and order activity in our primary served markets." ADE's second-quarter revenue and bookings strength was driven by continuing demand for the Company's industry-leading 200mm tools as well as 300mm inspection and metrology tools - such as WaferSight, NanoMapper and AWIS systems. Order strength has been strongest in the Asia Pacific region and Japan in recent months, and ADE expects that trend to continue in the months ahead. ADE Chief Financial Officer Brian James stated, "We continue to reap the benefits of our cost-reduction actions taken over the past two years. Coupled with our enhanced revenue performance, these actions enabled ADE to generate gross margins of 49 percent for the quarter, compared with 45 percent gross margins in the first quarter of fiscal 2004. In addition, ADE continued to generate positive cash flow and ended the quarter with nearly $35 million in cash and cash equivalents, which is up from $21.5 million at April 30, 2003." Looking Ahead "With demand for our advanced tools on the rise and our plans to roll out new products in coming months, ADE is positioned to respond to the semiconductor market and deliver further solid gains in the emerging up cycle," stated Dr. Koliopoulos. For the third quarter of fiscal 2004, ADE anticipates that revenues will increase sequentially by approximately 7-12%. Gross margins for the third quarter are expected to be in the range of 46 percent to 49 percent. Based on ADE's expectation that it will go to trial with KLA-Tencor on patent infringement issues in January, the Company anticipates a significant sequential increase in related general and administrative expenses. ADE expects that, even with these additional extraordinary expenses, it will report net income of between $0.06 and $0.09 per share for the third quarter of fiscal 2004.
