Introduction

This Amendment No. 3 to the Rule 13E-3 Transaction Statement (“Transaction Statement”) is being filed with the Securities and Exchange Commission (the “SEC”) pursuant to Section 13(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), by: (i) MEMSIC, Inc., a Delaware corporation (the “Company”); (ii) MZ Investment Holdings Limited, an exempted company with limited liability incorporated under the laws of the Cayman Islands (“Parent”); (iii) MZ Investment Holdings Merger Sub Limited, a Delaware corporation and wholly owned subsidiary of Parent (“Merger Sub”); (iv) IDG-Accel China Growth Fund II L.P., a limited partnership organized under the laws of the Cayman Islands, IDG-Accel China Investors II L.P., a limited partnership organized under the laws of the Cayman Islands, IDG Technology Venture Investments, L.P., a limited partnership organized under the laws of the State of Delaware, IDG Technology Venture Investments, LLC, a limited liability company organized under the laws of the State of Delaware, IDG Technology Venture Investment III, L.P., a limited partnership organized under the laws of the State of Delaware, and IDG-Accel China Capital II L.P., a limited partnership organized under the laws of the Cayman Islands (collectively, “IDG”); and (v) sixteen executive officers and employees of the Company and its subsidiaries, including Dr. Yang Zhao, Ph.D., Dr. Paul Zavracky, Ph.D., Patricia Niu, Yongyao Cai, Noureddine Hawat, Alexander Dribinsky, Dr. Eric Chojnacki, Ph.D., James Fennelly, Dr. Dong An, Ph.D., Lei Zhang, Wei Zhang, Haidong Liu, Leyue Jiang, John Newton, Jose Rios and Cheryl Merino (collectively, and together with IDG, the “Rollover Holders”).  The Rollover Holders, together with the Company, Parent and Merger Sub are referred to herein as the “Filing Persons.”

This Transaction Statement relates to the Agreement and Plan of Merger, dated as of April 22, 2013 (as it may be amended from time to time, the “Merger Agreement”) by and among the Company, Parent and Merger Sub. The Merger Agreement provides for the merger of Merger Sub with and into the Company (the “merger”). Pursuant to the terms of the Merger Agreement, the Company will be the surviving corporation in the merger and will continue its corporate existence under Delaware law, the corporate existence of Merger Sub will cease, and, immediately following the merger, Parent will own all of the outstanding capital stock of the Company.  At such time, the Rollover Holders will own all equity shares of Parent. Upon completion of the merger, each share of the Company’s common stock, par value $.00001 per share (“Common Stock”) (other than shares held by: (i) the Company as treasury stock; (ii) Parent or Merger Sub, whether directly or indirectly, and including any shares contributed to Parent by the Rollover Holders prior to the effective time of the merger in exchange for equity shares of Parent; (iii) any Company subsidiary; or (iv) stockholders who have properly exercised and perfected and not withdrawn or lost their appraisal rights under Delaware law), will be cancelled and converted into the right to receive $4.225 per share in cash (the “merger consideration”), without interest and less any applicable withholding taxes.  Following the completion of the merger, the Common Stock will no longer be publicly traded, and holders of the Common Stock that has been converted will cease to have any ownership interest in the Company.

The merger is subject to the satisfaction or waiver of various conditions set forth in the Merger Agreement, including the adoption of the Merger Agreement by the affirmative vote of Company stockholders representing at least a majority of the issued and outstanding Common

2

Stock.  Certain of the Rollover Holders that beneficially own 22.6% of the Company’s outstanding Common Stock have, subject to certain circumstances, agreed to vote their shares for the adoption of the Merger Agreement.

Concurrently with the filing of this Transaction Statement, the Company is filing with the SEC a definitive proxy statement (the “Proxy Statement”) under Regulation 14A of the Exchange Act, pursuant to which the Company’s board of directors is soliciting proxies in relation to a special meeting of the Company’s stockholders, where Company stockholders will be asked to consider and vote upon: (i) a proposal to adopt the Merger Agreement; (ii) a proposal to approve, on an advisory basis, specified compensation that may become payable to the named executive officers of the Company in connection with the merger; and (iii) a proposal to approve the adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the proposal to adopt the Merger Agreement. The Proxy Statement is attached hereto as Exhibit (a)(1). A copy of the Merger Agreement is attached to the Proxy Statement as Annex A and is incorporated herein by reference. As of the date hereof, the Proxy Statement is in preliminary form, and is subject to completion or amendment.

Pursuant to General Instruction F to Schedule 13E-3, the information in the Proxy Statement, including all annexes, exhibits and appendices thereto, is expressly incorporated by reference herein in its entirety, and responses to each item herein are qualified in their entirety by the information contained in the Proxy Statement. The cross-references below are being supplied pursuant to General Instruction G to Schedule 13E-3 and show the location in the Proxy Statement of the information required to be included in response to the items of Schedule 13E-3.
