SUNNYVALE, Calif. – June 23, 2004 – OmniVision Technologies, Inc. (Nasdaq: OVTI) reported that in the three months ended April 30, 2004, the fourth quarter of its fiscal year 2004, it earned net income of $20.8 million, or $0.34 per diluted share, on revenue of $99.7 million. In the fourth quarter of fiscal year 2003, the Company earned net income of $6.1 million, or $0.12 per diluted share, on revenue of $39.9 million.

In fiscal year 2004, the Company earned net income of $58.7 million, or $0.98 per diluted share, on revenue of $318.1 million. In fiscal year 2003, the Company earned net income of $15.3 million, or $0.31 per diluted share, on revenue of $109.0 million.

“Fiscal year 2004 was a period of dramatic expansion for our business,” said Shaw Hong, president and chief executive officer. “Our revenue grew by 192% year to year, as the cameraphone market emerged as our largest market segment. To build our organization, we expanded our testing operations in mainland China and opened new sales offices in several international markets. To enhance quality and deliverability, we made rapid progress with our manufacturing joint venture, VisEra, that we started with our foundry partner, Taiwan Semiconductor Manufacturing Company. This year we achieved growth that was unprecedented in our history and we emerged as a powerful force in the image sensor market. We are committed to an aggressive strategy of leveraging our many new products to support our current markets and to address large, developing markets.”

For the three months ended April 30, 2004, gross profit was $40.1 million, or 40.3% of revenue. In the comparable period a year ago, gross profit was $15.4 million, or 38.4% of revenue. For the three months ended April 30, 2004, direct sales to original equipment manufacturers and value added resellers accounted for approximately 80% of revenue, with the balance of approximately 20% coming from sales through distributors. During the quarter, total cash, cash equivalents and short-term investments increased by $18.1 million, to $215.2 million. As of April 30, 2004, working capital was $271.9 million, and stockholders’ equity was $300.0 million.

For the quarter ending July 31, 2004, the first quarter of fiscal 2005, the Company currently expects to report $95 million to $100 million in revenue and $0.29 to $0.31 in diluted earnings per share.

As previously disclosed, OmniVision has been conducting an internal review, a review which was initiated in response to issues raised by an employee. The Company notified the Audit Committee of the Board of Directors of the issues raised, and the Audit Committee conducted an independent investigation in cooperation with special legal counsel. As a result of the internal review and the independent investigation, management and the Audit Committee determined that certain errors had occurred which principally affected the timing of revenue recognition for certain sales.

The independent investigation concluded that there was no evidence of wrongdoing in connection with these errors. The Company, under direction from the Audit Committee, is in the process of making improvements to its internal controls and information systems.

As a result of the errors identified, OmniVision is restating its financial results for the first, second and third quarters of fiscal 2004. For the nine months ended January 31, 2004, the restatement increases revenue by $8.9 million, net income by $2.7 million and diluted earnings per share by $0.04 over the amounts previously reported.

The restatement of the Company’s financial results for first three quarters of fiscal 2004 relates primarily to two issues. First, beginning in the second half of fiscal 2003 and continuing through the first nine months of fiscal 2004, certain distribution sales, for which the Company recognizes revenue on a “sell-through” basis, were not reported to the Company by one of its distributors in a timely manner. Additionally, in the second and third quarters of fiscal 2004, during the transition of testing operations and certain international sales functions to overseas locations, some shipments made to customers late in the quarter were incorrectly classified as transferring title upon delivery as opposed to upon shipment, and therefore revenue was not recognized when product was shipped. Both of these issues resulted in delayed revenue recognition. Both management and the Audit Committee determined that the errors did not have material effects on quarterly or annual financial statements for fiscal 2003 and, consequently, decided not to restate the quarterly or annual financial results for such periods. The following table summarizes the effect of the restatement on each of first three quarters of fiscal 2004:

The Company currently anticipates filing amended Quarterly Reports on Form 10-Q for the first, second and third quarters of 2004 and its 2004 Annual Report on Form 10-K by July 14, 2004. The amended quarterly reports will contain the restated financial results described above.
