Agreement and Plan of Merger

On September 10, 2018, Integrated Device Technology, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Renesas Electronics Corporation, a Japanese corporation (“Renesas”). The Merger Agreement and the Merger (as defined below) have been approved by the boards of directors of the Company and Renesas

Structure. The Merger Agreement provides that, upon the terms and subject to the satisfaction or waiver of the conditions set forth therein, a wholly owned direct subsidiary of Renesas (to be formed following the Agreement Date as a Delaware corporation) (“Merger Sub”) will be merged with and into the Company (the “Merger”), with the Company continuing as the surviving corporation and a direct wholly owned subsidiary of Renesas.

Consideration . At the effective time of the Merger, each outstanding share of common stock, par value $0.001 per share, of the Company (a “Company Share”), other than shares held by stockholders who have validly exercised their appraisal rights under Delaware law, and certain shares owned by the Company, Renesas and their subsidiaries, will be automatically converted into the right to receive $49.00 in cash (the “Per Share Merger Consideration”), without interest.

Effect on Company Equity Awards . At the effective time of the Merger:

Covenants, Representations and Warranties . Each of the Company and Renesas have made customary representations, warranties and covenants in the Merger Agreement. The Company has made covenants, among others, relating to the conduct of its business prior to the closing of the Merger, including with respect to making acquisitions or conducting divestitures, incurring debt, making capital expenditures, certain litigation matters, and restrictions on employee compensation. The Company and Renesas made certain other customary covenants in the Merger Agreement. Renesas has also, subject to certain exceptions, agreed to provide Company employees continuing with Renesas after the Merger with comparable salaries, wages and benefits provided to such employees prior to the closing.

The Merger Agreement contains customary non-solicitation restrictions prohibiting the Company from soliciting alternative acquisition proposals from third parties or providing information to or participating in discussions or negotiations with third parties regarding alternative acquisition proposals, subject to customary exceptions relating to proposals that would reasonably be expected to lead to a superior proposal (as described in the Merger Agreement).

The Merger Agreement also contains covenants regarding the Company and Renesas using their respective reasonable best efforts to obtain all required governmental and regulatory consents and approvals.

Conditions to Merger . The closing of the Merger is subject to certain conditions, including, among others, (a) adoption of the Merger Agreement by at least a majority of all outstanding Company Shares, (b) the absence of certain laws, orders, judgments and injunctions that restrain, enjoin or otherwise prohibit the consummation of the Merger, (c) expiration or termination of the applicable Hart-Scott-Rodino Act waiting period and receipt of specified governmental and regulatory consents and approvals, (d) subject to certain exceptions, the accuracy of representations and warranties with respect to the businesses of the Company and Renesas and compliance in all material respects by the Company, Renesas and Merger Sub with their respective covenants contained in the Merger Agreement, and (e) the absence of a material adverse effect on the Company’s business. Consummation of the Merger is not subject to a financing condition.

Termination Rights . The Merger Agreement contains certain customary termination rights by either the Company or Renesas, including if the Merger is not consummated by June 10, 2019, subject to two (2) three-month extensions in order to obtain required regulatory approvals.

If the Merger Agreement is terminated under certain circumstances, including termination by the Company to enter into a superior alternative transaction, a termination by Renesas following an adverse recommendation change of the Company’s board of directors or a termination by Renesas as a result of a willful material breach of the Merger Agreement’s no-solicitation obligations by the Company, the Company will be obligated to pay to Renesas a termination fee equal to $166.4 million in cash. If the Merger Agreement is terminated under certain circumstances involving the failure to obtain certain regulatory approvals, including the approval of the Merger by the Committee on Foreign Investment in the United States, Renesas will be obligated to pay the Company a termination fee equal to $166.4 million in cash.

The foregoing description of the Merger Agreement is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is filed as Exhibit 2.1 hereto, and is incorporated into this report by reference.

The Merger Agreement has been included to provide investors with information regarding its terms. It is not intended to provide any other factual information about the Company or Renesas.
