Safe Harbor Statement Forward Looking Statements These slides and the accompanying oral presentation contain forward-looking statements and information. The use of words such as may, might, will, should, expect, plan, anticipate, believe, estimate, project, intend, future, potential or continue, and other similar expressions are intended to identify forward looking statements. All of these forward-looking statements are based on estimates and assumptions by our management that, although we believe to be reasonable, are inherently uncertain. Forward-looking statements involve risks and uncertainties, including, but not limited to, economic, competitive, governmental and technological factors outside of our control, that may cause our business, industry, strategy or actual results to differ materially from the forward-looking statements. These risks and uncertainties may include those discussed under the heading Risk Factors in the Company s most recent registration statement on Form S-1 on file with the Securities and Exchange Commission, and other factors which may not be known to us. Any forward-looking statement speaks only as of its date. We undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law. Regulation G Reconciliation During the course of this presentation, we may refer to historical and forward-looking non-gaap financial measures. A reconciliation of historical non-gaap financial measures with the most directly comparable GAAP financial measures can be found on our web site at www.entropic.com in the Investor Relations section. We have not provided a reconciliation of forward-looking non-gaap financial measures due to the difficulty in forecasting and quantifying the amounts that would be required to be included in the comparable GAAP measure that are dependent upon future market conditions and valuations.
