(Reverse of Security)

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities” and each, a “Security”) issued and to be issued in one or more series under and governed by the Senior Debt Securities Indenture, dated as of January 17, 2018 (as heretofore amended and supplemented, the “Base Indenture”), between the Company and The Bank of New York Mellon, London Branch, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture (as defined below)) as amended and supplemented by the Eighteenth Supplemental Indenture, dated as of September 10, 2024 (the “Eighteenth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), and reference is hereby made to the Indenture, the terms of which are incorporated herein by reference, for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. Insofar as the provisions of the Indenture may conflict with the provisions set forth in this Security, the Indenture shall control for purposes of this Security. All terms used in this Security that are defined in the Indenture and not otherwise defined herein shall have the meanings assigned to them in the Indenture.

This Security is one of the series designated on the face hereof, limited to an aggregate principal amount of $2,000,000,000, which amount may be increased at the option of the Company if in the future it determines that it may wish to sell additional Securities of this series. References herein to “this series” mean the series designated on the face hereof.

The provisions set forth in Section 10.04 of the Base Indenture are applicable to this Security. In addition, the Company agrees, to the extent the Company has actual knowledge of such information, to provide the Paying Agent with sufficient information about any modification to the terms of the Securities for the purposes of determining whether FATCA Withholding Tax applies to any payment of principal or interest on the Securities.

The Company may redeem the Securities pursuant to Section 2.04 of the Eighteenth Supplemental Indenture. The Company may also redeem the Securities pursuant to Section 11.09 of the Base Indenture and/or Section 2.05 of the Eighteenth Supplemental Indenture. Any redemption of Securities by the Company is subject to the notice period and provisions set forth in Sections 11.02 and 11.04 of the Base Indenture and in Section 2.06 of the Eighteenth Supplemental Indenture, and to the conditions set forth in Section 11.10 and Section 11.13 of the Base Indenture.

The Company may repurchase the Securities pursuant to Section 11.12 and Section 11.13 of the Base Indenture.

All authority conferred or agreed to be conferred by each Holder and Beneficial Owner pursuant to this Security, including the consents given by such Holder and Beneficial Owner, shall be binding upon the successors, assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of such Holder and Beneficial Owner.

The Securities shall constitute the Company’s direct, unconditional, unsecured and unsubordinated obligations and shall rank as set forth in Section 2.01(k) of the Eighteenth Supplemental Indenture.

C-8

The Securities are subject to the waiver of set-off provisions set forth in Section 5.01(h) of the Base Indenture.

This Security is subject to the provisions regarding the U.K. Bail-in Power Acknowledgement set forth in Section 12.01 of the Base Indenture.

The Securities are subject to provisions set forth in Article 5 of the Base Indenture.

If a Winding-Up Event occurs, the outstanding principal amount of this Security, together with any accrued but unpaid interest thereon, shall become immediately due and payable, without the need of any further action on the part of the Trustee, the Holders or any other Person.

If a Non-Payment Event occurs, the Trustee may at its discretion, and without further notice to the Company, institute proceedings in England (or such other jurisdiction in which the Company may be organized) (but not elsewhere) for the winding-up of the Company and/or prove in a winding-up of the Company and/or claim in a liquidation or administration of the Company.

Subject to applicable law, no Holder of Securities may exercise, claim or plead any right of set-off, compensation, counterclaim, retention or netting in respect of any amount owed to it by the Company arising under, or in connection with, the Securities and each Holder of Securities shall, by virtue of its holding of any Securities (or any beneficial interest therein), be deemed, to the fullest extent permitted under applicable law, to have waived all such rights of set-off, compensation, counterclaim, retention and netting. Notwithstanding the foregoing, if any amounts due and payable to any Holder of this Security by the Company in respect of, or arising under, this Security are discharged by set-off, compensation, counterclaim, retention or netting, such Holder shall, subject to applicable law, immediately pay an amount equal to the amount of such discharge to the Company (or, in the event of its winding-up or administration, the liquidator or administrator of the Company, as the case may be) and, until such time as payment is made, shall hold an amount equal to such amount in trust for the Company (or the liquidator or administrator of the Company, as the case may be) and, accordingly, any such discharge shall be deemed not to have taken place. By its acquisition of the Securities, each Holder and Beneficial Owner agrees to be bound by these provisions relating to waiver of set-off, compensation, counterclaim, retention and netting.

The Indenture permits the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities to be affected under the Indenture as contemplated by Article 9 of the Base Indenture. To the extent required by the U.S. Trust Indenture Act of 1939, as amended, but otherwise notwithstanding any other provision in this Security, the Holder of this Security shall have the right to receive (subject to Section 3.07 of the Base Indenture) payment of any principal of, and interest on, this Security when due (or, in the case of redemption, on or after the Redemption Date), and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder or holder.

This Security, and any other Securities of this series and of like tenor, are issuable only in registered form without coupons in initial denominations of $200,000 and increments of $1,000 thereafter. The denominations cannot be changed without the consent of the Trustee. The provisions on registration, transfer and exchange of the Securities set forth in Section 3.05 of the Base Indenture are applicable to the Securities.

C-9

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

This Security shall be governed by and construed in accordance with the laws of the State of New York, except for the waiver of set-off provisions referenced herein and set forth in Section 5.01(h) of the Base Indenture, which shall be governed by and construed in accordance with English law.

Ladies and Gentlemen:

We have acted as special U.S. counsel to Barclays PLC, a public limited company incorporated under the law of England and Wales (the “Company”), in connection with the Company’s offering pursuant to a registration statement on Form F-3 (No. 333-277578) of $1,000,000,000 4.837% Fixed-to-Floating Rate Senior Callable Notes due 2028 (the “2028 Notes”), $1,500,000,000 4.942% Fixed-to-Floating Rate Senior Callable Notes due 2030 (the “2030 Notes”) and $2,000,000,000 5.335% Fixed-to-Floating Rate Senior Callable Notes due 2035 (the “2035 Notes” and together with the 2028 Notes and the 2030 Notes, the “Securities”), to be issued under an indenture dated as of January 17, 2018 (as heretofore amended and supplemented, the “Base Indenture”), among the Company, The Bank of New York Mellon, London Branch, as trustee and paying agent (the “Trustee”), and The Bank of New York Mellon SA/NV, Luxembourg Branch, as registrar (the “Registrar”), as supplemented and amended by an eighteenth supplemental indenture dated as of September 10, 2024 (the “Eighteenth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), among the Company, the Trustee and the Registrar. Such registration statement, as amended as of its most recent effective date (September 3, 2024), insofar as it relates to the Securities (as determined for purposes of Rule 430B(f)(2) under the Securities Act of 1933, as amended (the “Securities Act”)), including the documents incorporated by reference therein but excluding Exhibits 25.1, 25.2 and 25.3, is herein called the “Registration Statement.”

In arriving at the opinion expressed below, we have reviewed the following documents:

Cleary Gottlieb Steen & Hamilton LLP is a Limited Liability Partnership registered in England and Wales Number OC310280. It is authorised and regulated

by the Solicitors Regulation Authority. A list of the members and their professional qualifications is open to inspection at the registered office,

2 London Wall Place, London EC2Y 5AU. Cleary Gottlieb Steen & Hamilton LLP or an affiliated entity has an office in each of the locations listed above.

Barclays PLC, Page 2

In addition, we have made such investigations of law as we have deemed appropriate as a basis for the opinion expressed below.

In rendering the opinion expressed below, we have assumed the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies. In addition, we have assumed and have not verified the accuracy as to factual matters of each document we have reviewed.

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that the Securities are valid, binding and enforceable obligations of the Company, entitled to the benefits of the Indenture; provided that we express no opinion as to the validity, binding effect or enforceability of the waiver of set-off provisions set forth in Section 5.01(h) of the Base Indenture and the corresponding provision in the Global Securities, which provisions are governed by English law.

Insofar as the foregoing opinion relates to the validity, binding effect or enforceability of any agreement or obligation of the Company, (a) we have assumed that the Company and each other party to such agreement or obligation has satisfied those legal requirements that are applicable to it to the extent necessary to make such agreement or obligation enforceable against it (except that no such assumption is made as to the Company regarding matters of the federal law of the United States of America or the law of the State of New York that in our experience normally would be applicable to general business entities with respect to such agreement or obligation), (b) such opinion is subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally and to general principles of equity, (c) we express no opinion with respect to the effect of any mandatory choice of law rules and (d) such opinion is subject to the effect of judicial application of foreign laws or foreign governmental actions affecting creditors’ rights.

We express no opinion as to the subject matter jurisdiction of any United States federal court to adjudicate any action relating to the Securities where jurisdiction based on diversity of citizenship under 28 U.S.C. §1332 does not exist.

The foregoing opinion is limited to the federal law of the United States of America and the law of the State of New York. With respect to matters governed by English law, we have relied on the opinion of Clifford Chance LLP dated September 10, 2024, as English counsel to the Company, which has been filed as Exhibit 5.2 to the Company’s Form 6-K dated September 10, 2024.

We hereby consent to the incorporation by reference of this opinion in the Registration Statement and the use of our name in the prospectus constituting a part of the Registration Statement and the prospectus supplement dated September 3, 2024 relating to the Securities under the heading “Validity of Notes.” In giving such consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Securities and Exchange Commission thereunder.

In connection with the creation and issue of the Notes and the giving of this Opinion:

- 2 -

This Opinion is governed by English law, relates only to English law as applied by the English courts as at today’s date and does not extend to the laws of any other jurisdiction (save as described in paragraph 1.5 (Taxation)). All non-contractual obligations and any other matters arising out of or in connection with this Opinion are governed by English law.

We express no opinion on any taxation matter, and none is implied or may be inferred, save as expressly specified in paragraph 2.3 (Taxation statements in the Base Prospectus). In respect of those tax matters this Opinion is confined to, and given on the basis of, English law, United Kingdom tax law and His Majesty’s Revenue and Customs (“HMRC”) published practice in force or applied in the United Kingdom as at today’s date.

This Opinion is given on the basis of our understanding of the terms of the Indenture and the Notes, and the assumptions set out in Schedule 2 (Assumptions) and is subject to the reservations set out in Schedule 3 (Reservations). This Opinion is strictly limited to the matters stated in paragraph 2 (Opinion) and does not extend to any other matters.

We are of the opinion that:

The Issuer is a company duly incorporated in England and has the capacity and power to create and issue the Notes, to enter into the Supplemental Indenture and to exercise its rights and perform its obligations under the Notes and the Indenture.

The issue of the Notes has been duly authorised by or on behalf of the Issuer.

The statements in the Base Prospectus under the heading “United Kingdom Taxation of Senior Debt Securities” as amended by the statements in the Prospectus Supplement under the heading “United Kingdom Tax Considerations” are, insofar as they are relevant to the Notes, correct in all material respects.

ASSUMPTIONS

Where, for the purposes of paragraphs 1(a) and 1(c) of this Schedule 2:

“sign” or “signed” means, in relation to the Indenture and/or each Global Note executed with an electronic signature, the process by which the signatory has applied such electronic signature to the Indenture (as applicable) and/or such Global Note; and

“electronic signature” means the signature in electronic form applied to the Indenture (as applicable) and/or any Global Note that is intended by the signatory to take effect as their signature including, without limitation, an image of the signatory’s handwritten signature, the typed name of the signatory, a signature generated by the signatory with a stylus on a touch pad or screen and any signature created by the signatory in accordance with the processes of an electronic signing platform.

Each party to the Indenture (other than the Issuer) has the capacity, power and authority to enter into and to exercise its rights and to perform its obligations under the Indenture.
