Forward-Looking Statements Notice:

The foregoing paragraphs contain forward-looking statements that involve estimates, assumptions, risks and uncertainties. Any statements about our expectations, beliefs, plans, objectives, assumptions or future events or performance are not historical facts and may be forward-looking. Such forward-looking statements include statements relating to: our expectation that we will continue to execute on the major strategic and operational initiatives designed to further accelerate our market penetration, and drive our revenue and EPS growth in the coming years; our statement that we may continue to repurchase additional shares of our common stock through February 2015; and those statements under the heading “Business Outlook - First Quarter 2015” relating to expected revenue, gross margin and total operating expenses. Other forward-looking statements may be indicated by words such as “will,” “could,” “should,” “would,” “may,” “expect,” “plan,” “project,” “anticipate,” “intend,” “forecast,” “future,” “believe,” “estimate,” “predict,” “propose,” “potential,” “continue” or the negative of these terms or other comparable terminology. Lattice believes the factors identified below could cause actual results to differ materially from the forward-looking statements.

Estimates of future revenue are inherently uncertain due to, among other things, the high percentage of quarterly “turns” business. In addition, revenue is affected by such factors as global economic conditions, which may affect customer demand, pricing pressures, competitive actions, the demand for our Mature, Mainstream and New products, and in particular our iCE40™ and MachXO3L™ devices, the ability to supply products to customers in a timely manner, changes in our distribution relationships, or the volatility of our consumer business. Actual gross margin percentage and operating expenses could vary from the estimates on the basis of, among other things, changes in revenue levels, changes in product pricing and mix, changes in wafer, assembly, test and other costs, including commodity costs, variations in manufacturing yields, the failure to sustain operational improvements, the actual amount of compensation charges due to stock price changes. Any unanticipated declines in revenue or gross margin, any unanticipated increases in our operating expenses or unanticipated charges could adversely affect our profitability.

In addition to the foregoing, other factors that may cause actual results to differ materially from the forward-looking statements in this press release include global economic uncertainty, overall semiconductor market conditions, market acceptance and demand for our new products, the Company's dependencies on its silicon wafer suppliers, the impact of competitive products and pricing, technological and product development risks, the risk that the Silicon Image transaction will not close when expected or at all, the risk that the operations of the two companies will not be integrated successfully, the failure to achieve the anticipated benefits and synergies of the transaction, the risk that Lattice or Silicon Image’s business will be adversely impacted during the pendency of the transaction, costs associated with the transaction; matters arising in connection with the parties’ efforts to comply with and satisfy applicable regulatory approvals and closing conditions relating to the transaction, and other events that could adversely impact the completion of the transaction, including industry or economic conditions outside of the control of Lattice and Silicon Image. In addition, actual results are subject to other risks and uncertainties that relate more broadly to our overall business, including those risks more fully described in Lattice’s filings with the SEC including its annual report on Form 10-K for the fiscal year ended December 28, 2013, and Lattice’s quarterly reports filed on Form 10-Q for the 2014 fiscal year, and those more fully described in Silicon Image’s filings with the SEC including its annual report on Form 10-K for the fiscal year ended December 31, 2013, and its quarterly reports filed on Form 10-Q for the 2014 fiscal year.
