EXPLANATORY NOTE

Mindspeed Technologies, Inc. (the Company) is filing this Amendment No. 1 on Form 10-Q/A (Amendment) to
amend its Quarterly Report on Form 10-Q for the quarterly period ended March 29, 2013 (the Form 10-Q), originally filed with the Securities and Exchange Commission on May 8, 2013. The purpose of this Amendment is to file
Exhibit 10.2 and Exhibit 10.3 that were intended to be originally filed with the Form 10-Q and were mistakenly omitted from the filing. No revisions are being made to the Companys financial statements. This Amendment speaks as of the original
filing date, does not reflect events occurring after the filing of the Form 10-Q, or modify or update those disclosures that may be affected by subsequent events, and no other changes are being made to any other disclosure contained in the Form
10-Q. Except for the filing of Exhibit 10.2 and Exhibit 10.3, this Amendment does not otherwise amend any exhibits as originally filed.

In addition, as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the Exchange Act), new certifications by the Companys principal executive officer and
principal financial officer are filed herewith as exhibits to this Amendment pursuant to Rule 13a-14(a) of the Exchange Act. The Company is not including certifications pursuant to Section 1350 of Chapter 63 of Title 18 of the United States
Code (18 U.S.C. 1350) as no financial statements are being filed with this Amendment.
