  • Omnivision Technologies, Inc 10-K
    To my fellow stockholders, Fiscal 2011 was an exciting and rewarding year for OmniVision as major tasks were accomplished and many performance records were set. Our key objectives in fiscal 2011 were threefold: • Continue the successful ramp of our OmniBSI devices, • Continue the development and implementation of our OmniBSI-2 technology, and • Capitalize on the growth and expansion opportunities presented by the image sensor markets with our advanced proprietary technology. We believe we have accomplished these goals, and are now resolved to maintain the momentum we have achieved. Fiscal Year Financial Results In fiscal 2011, revenues reached $956.5 million, approaching the $1 billion mark for the first time in our company history. Our net income for fiscal 2011 was $124.5 million, or $2.11 per diluted share. All of these financial metrics showed significant, if not record, improvement over fiscal 2010. Our balance sheet further demonstrated our focus on financial performance and the company’s overall strength in a competitive market. We ended the year with cash, cash equivalents and short-term investments of $466.9 million. Technology Achievements OmniVision takes great pride in its successful record of innovation. Specifically, our expertise in implementing the OmniBSI technology has positioned OmniVision as a leading component supplier, providing image sensors to a wealth of products, including high-end smartphones, notebooks, webcams, portable multi-media devices and even commercial enterprise applications. Our portfolio of image sensors now extends from VGA up to 14 megapixels, all meeting demanding performance standards. It is this wide range of offerings, as well as the depth of our expertise, that enabled the company to ship more than 680 million CMOS image sensors last year.

  • Omnivision Technologies, Inc
    TM 2009 Annual Report To my fellow stockholders, The past twelve months have been challenging for OmniVision and many other companies. We completed our 2009 fiscal year on April 30, 2009 as the global economic downturn continued to impact companies and markets worldwide. Against this background, our fiscal 2009 revenues decreased for the first time since 2002 on a year-over-year basis. Our fiscal 2009 revenues were $507.3 million and we recorded a net loss of $37.3 million, or $0.74 per share. Despite the challenging economic conditions, we are pleased with a number of our accomplishments during the past year, which include significant new technological and product introductions, continuation of our market share leadership, and further strengthening of our financial position. We also believe that this challenging environment creates an opportunity for us to capitalize on our long-term corporate strategy and to continue to gain market share. Backed by our strong balance sheet with over $275 million in cash, cash equivalents and short-term investments at fiscal 2009 year-end, we remain confident regarding our long-term growth prospects and committed to delivering value for our stockholders. Our Corporate Strategy At the heart of our corporate strategy are three key elements: • the wise investment in the development of new technology that enables us to continue to introduce market-leading products; • the development of new and emerging product markets and geographies; and • our continuing seamless collaboration with our supply chain partners, TSMC and VisEra, and XinTec, to efficiently and effectively manage our supply chain. Continuing Investment in New Technology First and foremost, we are a technology company.
