(Attach extra Sheets if Needed)

Marvell Technology Group Ltd. (“Company”) has determined that it is unable to file its Quarterly Report on Form 10-Q for the quarter ended August 1, 2015 (“Quarterly Report”) within the prescribed time period without unreasonable effort or expense for the reasons described below.

As disclosed in the Company’s press release dated September 11, 2015, the Audit Committee of the Company’s Board of Directors is conducting an independent investigation of certain accounting and internal control matters in the second quarter of fiscal 2016. The investigation consists of a review of certain revenue recognition issues in the second quarter of fiscal 2016 and any associated issues with whether senior management’s operating style during the period resulted in an open flow of information and communication to set an appropriate tone for an effective control environment. More specifically, the investigation has focused on the approximately 7 to 8 percent of revenue recognized in the second quarter of fiscal 2016 that, based upon the original customer request date, would have been received and earned in the third quarter of fiscal 2016 and is now no longer available for receipt in that quarter. Such percentage represents an increase over the prior four quarters and is indicative of softening demand for certain of the Company’s products. This was particularly the case in the storage end market where, as a result of a weaker global economy and a slow-down in the PC market, the Company saw weaker than expected demand for HDD products as the overall total available market declined. The Audit Committee’s investigation to date has revealed no material issues regarding the Company’s 2016 second quarter financial results, and the Company believes the investigation will have no material impact on its previously issued financial statements. The Audit Committee is also reviewing certain aspects of the Company’s internal control over financial reporting, including controls for the establishment of reserves for litigation and whether senior management’s operating style resulted in an open flow of information and communication to set an appropriate tone for an effective control environment. The Company’s review of such internal controls is ongoing and may ultimately affect management’s conclusion of the effectiveness of internal control over financial reporting as of the end of the second quarter of fiscal 2016. For these reasons the Company has experienced a delay in the completion of its financial statements, Management’s Discussion and Analysis of Financial Condition and Results of Operations and other related components of the Quarterly Report.

The Audit Committee and Company management are also discussing potential enhancements to the Company’s internal controls and remedial actions to address the items discussed above and the adequacy of financial reporting resources. As a result, the Company is not providing any guidance as to the expected results for the third quarter of fiscal 2016 at this time.

This document 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. These forward-looking statements often include words such as “believe,” “expect,” “will,” or similar expressions. These statements are not guarantees of results, and our actual results could differ materially from those expressed in the forward-looking statements due to a variety of important factors, both positive and negative, including that additional issues or facts may be identified during the Audit Committee’s investigation that could cause material impacts on the Company’s historical or anticipated financial results. The Company therefore cautions you against relying on these forward-looking statements. All forward-looking statements attributable to the Company or persons acting on the Company’s behalf are expressly qualified in their entirety by the foregoing cautionary statements. All such statements speak only as of the date made, and, except as required by law, the Company undertakes no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise.
