EXPLANATORY NOTE

TriQuint Semiconductor, Inc. (“TriQuint”) is filing this Post-Effective Amendment to Form S-8 to withdraw and remove from registration certain securities issuable under the 1998 Employee Stock Purchase Plan, which was originally registered on a registration statement on Form S-8 (File No. 333-125269) filed with the Securities and Exchange Commission on May 26, 2005 (the “Registration Statement”).

On January 1, 2015, pursuant to an Agreement and Plan of Merger and Reorganization, dated as of February 22, 2014 and amended as of July 15, 2014 by and among TriQuint, RF Micro Devices, Inc. (“RFMD”) and Qorvo, Inc., a Delaware corporation, f/k/a Rocky Holding, Inc. (“Qorvo”), Trident Merger Sub, a direct subsidiary of Qorvo, merged with and into TriQuint, and Rocky Merger Sub, a direct subsidiary of Qorvo, merged with and into RFMD (the “Mergers”).

As a result of the Mergers, TriQuint terminated all offerings of its securities pursuant to its existing registration statements, including the Registration Statement. In accordance with an undertaking made by TriQuint in the Registration Statement to remove from registration, by means of a post-effective amendment, any of the securities registered under the Registration Statement that remain unsold at the termination of the offerings, TriQuint hereby removes from registration all remaining securities registered under the Registration Statement, if any.
