[2] Safe Harbor This presentation contains forward-looking statements that involve estimates, assumptions, risks and uncertainties, including statements relating to our expectation that we will continue to successfully execute on the return-to-growth strategy we outlined at last fall’s investor day; and the statements under the heading “Business Outlook - Second Quarter of 2018.” Factors that may cause actual results to differ materially from the forward-looking statements in this presentation include global economic uncertainty, overall semiconductor market conditions, market acceptance and demand for our new and existing products, the Company's dependencies on its silicon wafer suppliers, the impact of competitive products and pricing, technological and product development risks. 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 31, 2017 and quarterly filings. Certain information in this presentation is identified as having been prepared on a non-GAAP basis. Management uses non- GAAP measures to better assess operating performance and to establish operational goals. Non-GAAP information should not be viewed by investors as a substitute for data prepared in accordance with GAAP. You should not unduly rely on forward-looking statements because actual results could differ materially from those expressed in any forward-looking statements. In addition, any forward-looking statement applies only as of the date on which it is made. The Company does not intend to update or revise any forward-looking statements, whether as a result of events or circumstances after the date hereof or to reflect the occurrence of unanticipated events.

Q1 2018 Gross margin was 57.3% on a GAAP basis and 57.6% on a non- GAAP basis.  Meaningful sequential improvement reflects improved customer and product mix, as well as the benefit of prior inventory and cost reduction actions taken by Lattice. Q1 2018 Operating expenses were $57.3 million on a GAAP basis and $45.4 million on a Non-GAAP basis.  Non-GAAP OpEx was about $2 million above expectations primarily due to $2.4 million in non-recurring expenses.  GAAP OpEx includes approximately $5.6 million in Amortization of acquired intangible assets; $1.0 million in Restructuring charges; and $4.6 million in Stock-based compensation – operations.
