EXPLANATORY NOTE

Peregrine Semiconductor Corporation is filing this Amendment No. 1 on Form 10-K/A (this “Amendment”) to its annual report on Form 10-K for the fiscal year ended December 28, 2013, which was originally filed on February 19, 2014 (the “Original Filing”), to amend Part II, Item 9A of the Original Filing. This Amendment provides our management’s annual report on internal control over financial reporting required by Item 308 (a) of Regulation S-K. This Amendment also revises our conclusions regarding the effectiveness of our disclosure controls and procedures solely as a result of (i) our failure to file our management’s annual report on internal control over financial reporting in the Original Filing and (ii) our failure to include the language of paragraph 4(b) required by Item 601(b)(31) of Regulation S-K in the certifications filed with the Original Filing. As part of the 10-K/A, this Amendment amends Part IV, Item 15 for the sole purpose of amending and restating the Exhibit 31.1 and 31.2, Certifications of the Principal Executive Officer and Principal Financial Officer to add the language of paragraph 4(b) in accordance with Item 601(b)(31).

Except with respect to the above change, this Amendment does not modify or update any other disclosures set forth in the Original Filing.

PART II

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as of December 28, 2013. The term “disclosure controls and procedures,” as defined in Rules 13a- 15(e) and 15d- 15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation of our disclosure controls and procedures as of December 28, 2013, our Chief Executive Officer and Chief Financial Officer concluded that as of such date, our disclosure controls and procedures were not effective at the reasonable assurance level for the reasons specified in the Explanatory Note to this annual report on Form 10-K/A .

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the three months ended December 28, 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting

The Company acknowledges that it is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) of the Securities Exchange Act of 1934. The Company’s internal controls over financial reporting are designed to provide reasonable assurance with generally accepted accounting principles. The Company evaluated the effectiveness of its internal control over financial reporting as of December 28, 2013 using the criteria set forth in the 1992 version of the Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on management’s evaluation, the Company has concluded that it maintained effective internal control over financial reporting as of December 28, 2013 based on the COSO criteria. This annual report does not include an attestation report of the company’s registered public accounting firm due to a transition period established by rules of the Securities and Exchange Commission for emerging growth companies.

Limitations on the Effectiveness of Controls

Control systems, no matter how well conceived and operated, are designed to provide a reasonable, but not an absolute, level of assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected, and misstatements due to error or fraud may occur and not be detected.
