Forward-Looking Statements

This press release contains “forward-looking” statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, that involve risks and uncertainties. In some cases, you can identify these forward-looking statements by the use of terms such as “expect,” “will,” “continue,” or similar expressions, and variations or negatives of these words, but the absence of these words does not mean that a statement is not forward-looking. All statements other than statements of historical fact are statements that could be deemed forward-looking statements, including, but not limited to: any statements regarding the expected timing of the completion of the transaction and the benefits of the transaction; the ability of Dialog Semiconductor plc ("Dialog") and Adesto Technologies Corporation ("Adesto") to complete the proposed transaction considering the various conditions to the transaction, some of which are outside the parties’ control, including those conditions related to regulatory approvals; any other statements of expectation or belief; and any statements of assumptions underlying any of the foregoing. These forward-looking statements are inherently uncertain, and are based on information available to each of Dialog and Adesto as of the date hereof and current expectations, forecasts, estimates, and assumptions. A number of important factors and uncertainties could cause actual results or events to differ materially from those described in these forward-looking statements, including without limitation: the failure to satisfy or waive any of the conditions to the consummation of the proposed transaction, including the adoption of the Merger Agreement by Adesto’s stockholders and the receipt of certain governmental and regulatory approvals; matters arising in connection with the parties’ efforts to comply with and satisfy applicable regulatory approvals and closing conditions relating to the proposed transaction; the risk that the proposed transaction does not close when anticipated or at all; the effects of disruption from the transactions contemplated by the Merger Agreement on Adesto’s or Dialog’s business and the fact that the announcement and pendency of the transaction may make it more difficult to establish or maintain relationships with employees, suppliers and other business partners; the occurrence of any event, change or other circumstance that could give rise to the termination of the Merger Agreement; the outcome of any legal proceedings that may be instituted against Adesto or Dialog related to the Merger Agreement or the proposed transaction; unexpected costs, charges or expenses resulting from the proposed transaction; the occurrence of a Material Adverse Effect (as defined in the Merger Agreement); and other risks that are described in the reports of Adesto filed with the Securities and Exchange Commission (the “SEC”), including but not limited to the risks described in Adesto’s Annual Report on Form 10-K for its fiscal year ended December 31, 2018, which was filed with the SEC on March 18, 2019, and Adesto’s Quarterly Reports on Form 10-Q, and that are otherwise described or updated from time to time in other filings with the SEC. All forward-looking statements attributable to Adesto or Dialog, or persons acting on behalf of either, are expressly qualified in their entirety by this cautionary statement. Further, Adesto and Dialog disclaim any obligation to update the information in this communication or to announce publicly the results of any revisions to any of the forward-looking statements to reflect future events or developments, except as otherwise required by law. Readers are cautioned not to place undue reliance on these forward-looking statements that speak only as of the date hereof.
