W I T N E S S E T H :

WHEREAS the Issuer, the Parent Guarantor and the Subsidiary Guarantors have heretofore executed and delivered to the Trustee an indenture executed by and between the Issuer, the guarantors party thereto and the Trustee, dated as of January 17, 2024 (as amended, supplemented or otherwise modified, the “Indenture”), providing initially for the issuance of $800,000,000 in aggregate principal amount of the Issuer’s 5.650% First Priority Senior Secured Notes due 2034 (the “Securities”);

WHEREAS Amcor plc is an indirect parent of the Issuer; and

WHEREAS pursuant to Section 9.01 of the Indenture, the Trustee, the Issuer and the New Guarantors are authorized to execute and deliver this Supplemental Indenture;

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, each New Guarantor, the Issuer and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders as follows:

1.Defined Terms. As used in this Supplemental Indenture, terms defined in the Indenture or in the preamble or recital hereto are used herein as therein defined. The words “herein,” “hereof” and “hereby” and other words of similar import used in this Supplemental Indenture refer to this Supplemental Indenture as a whole and not to any particular section hereof.

2.Agreement to Guarantee.

(a) Each New Guarantor hereby agrees to irrevocably and unconditionally guarantee on a senior basis, as a primary obligor and not merely as a surety, to each Holder, the Trustee, the Collateral Agent and their successors and assigns the Guaranteed Obligations (the “New Guarantees”). Each New Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from such New

Guarantor, and that no extension or renewal of any Guaranteed Obligation shall release the obligations of such New Guarantor hereunder. The obligations of each New Guarantor hereunder shall be joint and several with the New Guarantees of the other New Guarantors. Each New Guarantor waives presentation to, demand of payment from and protest to the Issuer of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each New Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each New Guarantor hereunder shall not be affected by (i) the failure of any Holder, the Trustee or the Collateral Agent to assert any claim or demand or to enforce any right or remedy against the Issuer or any other Person under this Indenture, the Securities or any other agreement or otherwise; (ii) any extension or renewal of this Indenture, the Securities or any other agreement; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement; (iv) the release of any security held by the Collateral Agent on behalf of each Holder and the Trustee for the Guaranteed Obligations or any Subsidiary Guarantor; or (v) the failure of any Holder, the Trustee or the Collateral Agent to exercise any right or remedy against any other guarantor of the Guaranteed Obligations. Each New Guarantor hereby waives any right to which it may be entitled to have its obligations hereunder divided among itself and the other New Guarantors, such that such New Guarantor’s obligations would be less than the full amount claimed. Each New Guarantor hereby waives any right to which it may be entitled to have the assets of the Issuer first be used and depleted as payment of the Issuer’s or such New Guarantor’s obligations hereunder prior to any amounts being claimed from or paid by such New Guarantor hereunder. Each New Guarantor hereby waives any right to which it may be entitled to require that the Issuer be sued prior to an action being initiated against such New Guarantor. Each New Guarantor further agrees that its New Guarantee constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder, the Trustee or the Collateral Agent to any security held for payment of the Guaranteed Obligations.

(b) Except as expressly set forth in Section 8.01(b) of the Indenture, the obligations of each New Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each New Guarantor shall not be discharged or impaired or otherwise affected by the failure of any Holder, the Trustee or the Collateral Agent to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such New Guarantor or would otherwise operate as a discharge of such New Guarantor as a matter of law or equity.

(c) Each New Guarantor agrees that its New Guarantee shall remain in full force and effect until payment in full of all the Guaranteed Obligations. Each New Guarantor further agrees

that its New Guarantee shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder, the Trustee or the Collateral Agent upon the bankruptcy or reorganization of the Issuer or otherwise.

(d) In furtherance of the foregoing and not in limitation of any other right which any Holder, the Trustee or the Collateral Agent has at law or in equity against each New Guarantor by virtue hereof, upon the failure of the Issuer to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each New Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Trustee an amount equal to the sum of (i) the unpaid principal amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by applicable law) and (iii) all other monetary obligations of the Issuer to the Trustee.

(e) Each New Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Trustee in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. Each New Guarantor further agrees that, as between it, on the one hand, and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article 6 of the Indenture for the purposes of the New Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6 of the Indenture, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such New Guarantor for the purposes hereof.

(f) For the avoidance of doubt, each New Guarantor will not be subject to any of the restrictive covenants contained in the Indenture or any of the other obligations or agreements of a Subsidiary Guarantor or Parent Guarantor thereunder.

(g) For the avoidance of doubt, so long as Amcor plc is an indirect parent of the Issuer, the Issuer may satisfy its obligations under Section 4.02 of the Indenture by furnishing financial information relating to Amcor plc; provided that the same is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to Amcor plc and any of its Subsidiaries other than the Issuer and its Subsidiaries, on the one hand, and the information relating to the Issuer, the Subsidiarity Guarantors and the other Subsidiaries of the Issuer on a standalone basis, on the other hand.

3.3. Limitation on Liability

(a) Any term or provision of the Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any New Guarantor (except Amcor plc) shall not exceed the maximum amount that can be hereby guaranteed without rendering the Indenture, as it relates to such New Guarantor, voidable under applicable law

relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

(b) A New Guarantee as to any New Guarantor (except Amcor plc) shall terminate and be of no further force or effect and such New Guarantor shall be deemed to be released from all obligations under Section 2 of this Supplemental Indenture upon:

(i) the sale, disposition or other transfer (including through merger or consolidation) of all the Capital Stock of the applicable New Guarantor,

(ii) such New Guarantor no longer guaranteeing the First Priority Lien Obligations, and

(iii) with respect to each applicable series of Securities, the Issuer’s exercise of its defeasance option with respect to such series of Securities under Article 8, or if the Issuer’s obligations under the Indenture are discharged in accordance with the terms of the Indenture.

4.4. Notices. Any notice or communication to any New Guarantor required or permitted hereunder shall be in writing and delivered in person, via facsimile or mailed by first-class mail addressed as follows:
