Rick White, CVP Operations/Supply Chain

In keeping with our 30+ year commitment to providing our Customers and Sales Partners with highly-differentiated solutions, Lattice Semiconductor is proud to announce that we have entered into a definitive agreement to acquire Silicon Image, a leading provider of wired and wireless application specific standard product (ASSP) connectivity solutions. The combined company will bring leading edge solutions and intellectual property, and unparalleled support, to the marketplace that we jointly serve. It is also important to note the combined company will represent a first-of-its-kind combination that is unique to the semiconductor industry. Never before has a single company been able to address the innovator, early-adopter market via FPGAs and also capture mainstream revenue opportunities through ASSPs. The new combined company will have the right technology, the right products, and the right people at the right time in the market!

Until you hear otherwise, please continue to conduct your day to day business with Lattice or Silicon Image as you have done previously. Our transaction is subject to a number of contingencies, including the tender of sufficient shares by Silicon Image stockholders and regulatory approvals. Once these contingencies are satisfied, the integration of the two companies will take us several months to complete. I assure you that there will be no interruption in your day to day communication with us. We will communicate frequently and openly during this process. As you may imagine, we are very excited about this acquisition and look forward to the many benefits it will bring to all of us.

Please feel free to contact me or Fina Borda, VP Asia Operations, directly if you have any questions or concerns.
