We do not express any opinion with respect to the laws of any jurisdiction other than (i) the laws of the State of New York and (ii) the General Corporation Law of the State of Delaware (the “DGCL”) (all of the foregoing being referred to as “Opined-on Law”).

As used herein, “Transaction Documents” means the Dealer Manager Agreement, the Indenture and the Note Certificates.

Based upon the foregoing and subject to the qualifications and assumptions stated herein, we are of the opinion that the Note Certificates have been duly authorized by all requisite corporate action on the part of the Company and, when the Note Certificates have been duly executed by the Company under the DGCL and duly authenticated by the Trustee and issued and delivered by the Company upon consummation of the Offers against receipt of the Qorvo Notes to be surrendered in exchange therefor in accordance with the terms of the Offers, the Note Certificates will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms under the laws of the State of New York.

The opinions stated herein are subject to the following assumptions and qualifications:

(a)             we do not express any opinion with respect to the effect on the opinions stated herein of any bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer, preference and other similar laws or governmental orders affecting creditors’ rights generally, and the opinions stated herein are limited by such laws and governmental orders and by general principles of equity (regardless of whether enforcement is sought in equity or at law);

(b)             we do not express any opinion with respect to any law, rule, regulation or order that is applicable to any party to any of the Transaction Documents or the transactions contemplated thereby solely because such law, rule, regulation or order is part of a regulatory regime applicable to any such party or any of its affiliates as a result of the specific assets or business operations of such party or such affiliates;

(c)             except to the extent expressly stated in the opinions contained herein, we have assumed that each of the Transaction Documents constitutes the valid and binding obligation of each party to such Transaction Document, enforceable against such party in accordance with its terms;

(d)             we do not express any opinion with respect to the enforceability of any provision contained in any Transaction Document relating to any indemnification, contribution, non-reliance, exculpation, release, limitation or exclusion of remedies, waiver or other provisions having similar effect that may be contrary to public policy or violative of federal or state securities laws, rules, regulations or orders, or to the extent any such provision purports to waive or alter, or has the effect of waiving or altering, any statute of limitations;

(e)             we do not express any opinion whether the execution or delivery of any Transaction Document by the Company, or the performance by the Company of its obligations under any Transaction Document will constitute a violation of, or a default under, any covenant, restriction or provision with respect to financial ratios or tests or any aspect of the financial condition or results of operations of the Company or any of its subsidiaries;

(f)              the opinions stated herein are limited to the agreements and documents specifically identified in the opinions contained herein (the “Specified Documents”) without regard to any agreement or other document referenced in any Specified Document (including agreements or other documents incorporated by reference or attached or annexed thereto) and without regard to any other agreement or document relating to any Specified Document that is not a Transaction Document;

(g)             this opinion letter shall be interpreted in accordance with customary practice of United States lawyers who regularly give opinions in transactions of this type;

(h)             we have assumed that the Base Indenture and the Supplemental Indentures will be executed and delivered by the parties thereto in substantially the form reviewed by us;

(i)              subsequent to the effectiveness of the Indenture and immediately prior to the effectiveness of Supplemental Indentures, the Indenture has not been amended, restated, supplemented or otherwise modified in any way that affects or relates to the Note Certificates other than by the applicable Transaction Documents relating to such series of Securities;

(j)              we do not express any opinion with respect to the enforceability of any Transaction Document to the extent that any Transaction Document purports to bind the Company to the exclusive jurisdiction of any particular federal court or courts;

(k)             we call to your attention that irrespective of the agreement of the parties to any Transaction Document, a court may decline to hear a case on grounds of forum non conveniens or other doctrine limiting the availability of such court as a forum for resolution of disputes; in addition, we call to your attention that we do not express any opinion with respect to the subject matter jurisdiction of the federal courts of the United States of America in any action arising out of or relating to any Transaction Document; and

(l)              to the extent that any opinion relates to the enforceability of the choice of New York law and choice of New York forum provisions contained in any Transaction Document, the opinions stated herein are subject to the qualification that such enforceability may be subject to, in each case, (i) the exceptions and limitations in New York General Obligations Law Sections 5-1401 and 5-1402 and (ii) principles of comity and constitutionality.

In addition, in rendering the foregoing opinions we have also assumed that, at all applicable times:

(a)             neither the execution and delivery by the Company of the Transaction Documents nor the performance by the Company of its obligations thereunder, including the issuance and sale of each series of the Securities: (i) constituted or will constitute a violation of, or a default under, any lease, indenture, agreement or other instrument to which the Company or its property is subject (except that we do not make the assumption set forth in this clause (i) with respect to those agreements or instruments expressed to be governed by the laws of the State of New York which are listed in Part II of the Registration Statement or the Company’s Annual Report on Form 10-K for the year ended October 3, 2025), (ii) contravened or will contravene any order or decree of any governmental authority to which the Company or its properties is subject, or (iii) violated or will violate any law, rule or regulation to which the Company or its properties is subject (except that we do not make the assumption set forth in this clause (iii) with respect to the Opined-on Law); and

(b)             neither the execution and delivery by the Company of the Transaction Documents nor the performance by the Company of its obligations thereunder, including the issuance and sale of each series of Securities, required or will require the consent, approval, licensing or authorization of, or any filing, recording or registration with, any governmental authority under any law, rule or regulation of any jurisdiction.

We hereby consent to the reference to our firm under the heading "Legal Matters" in the prospectus forming part of the Registration Statement.
