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 the first quarter will represent a low point in revenue for the year, followed by a healthy uptick in the second half of 2016; that we are firmly on track to outpace expected overall industry growth; our expectation for the planned second half ramp of wins at major consumer OEM’s; our expectation that we are benefiting from diversification of Greenfield markets, as we build on the high value, high performance proposition only Lattice is delivering to customers; our belief that gross margin will be more in-line with our long-term, mid-50’s percent target, as the revenue contribution from our consumer business again rebounds during the year; and those statements under the heading “Business Outlook - Second Quarter 2016” 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.
