This Certificate is not exchangeable for Definitive Warrant Certificates (as defined in the Warrant Agreement) registered in the name of a person other than the Depository or its nominee, except in the limited circumstances described in the Warrant Agreement, and no transfer of this Certificate (other than a transfer as a whole by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor depository or a nominee of such successor depository) may be registered except in the limited circumstances described in the Warrant Agreement.

Unless this certificate is presented by an authorized representative of the Depository to the Company or its agent for registration of transfer, exchange or payment, and any certificate issued is registered in the name of CEDE & CO. or in such other name as requested by an authorized representative of the Depository (and any payment is made to CEDE & CO. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, CEDE & CO., has an interest herein.

NEITHER THIS CERTIFICATE NOR ANY WARRANT OBLIGATIONS (AS DEFINED HEREIN) REPRESENTED HEREBY IS A SAVINGS ACCOUNT OR A DEPOSIT AND IS NOT INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENTAL AGENCY OR INSTRUMENTALITY AND IS NOT AN OBLIGATION OF OR GUARANTEED BY BANK OF AMERICA, N.A. OR ANY OTHER BANKING OR NONBANKING AFFILIATE OF BANK OF AMERICA CORPORATION.

THIS CERTIFICATE AND THE WARRANT OBLIGATIONS REPRESENTED HEREBY ARE UNSECURED CONTRACTUAL OBLIGATIONS OF BofA FINANCE LLC. THE PAYMENTS DUE ON THIS CERTIFICATE AND THE WARRANT OBLIGATIONS REPRESENTED HEREBY ARE FULLY AND UNCONDITIONALLY GUARANTEED BY THE GUARANTOR AS MORE FULLY SET FORTH IN THE WARRANT AGREEMENT.

This Certificate represents one or more series of Warrants (as such term “Warrants” is defined in the Warrant Agreement) which may be issued by the Company from time to time in one or more offerings up to the maximum amount duly authorized from time to time under the Company’s securities issuance program referred to as Warrants, Series B by the Company’s board of managers (the “Board of Managers”), or an officer of the Company authorized by the Board of Managers (each series of such Warrants, a “Warrant Obligation”). The terms and provisions of each Warrant Obligation are and will be reflected in this Certificate and in (i) the applicable “pricing supplement” related to such Warrant Obligation identified by CUSIP number and title of Warrant Obligation on Schedule 1 hereto and/or, as applicable, the applicable records of the Warrant Agent (including the Warrant Register) (with respect to such Warrant Obligation, the “Applicable Pricing Supplement”) and (ii) the applicable terms and provisions set forth in (a) the section entitled “Description of Warrants of BofA Finance LLC” contained in the Company’s Prospectus dated    , 2025, as it may be supplemented, amended, superseded or replaced by another prospectus as of the date of the Applicable Pricing Supplement (the “Prospectus”) (b) the section entitled “Description of the Warrants” contained in Company’s Prospectus Supplement relating to its warrants, Series B dated , 2025, as it may be supplemented, amended, superseded or replaced by another prospectus supplement as of the date of the Applicable Pricing Supplement (the “Prospectus Supplement”) and (c) and any similarly entitled section of any other prospectus supplement, including any product supplement, referred to in such Applicable Pricing Supplement (each such supplement, an “Additional Incorporated Supplement”) (the applicable terms and provisions of an applicable Warrant Obligation described in (i) – (ii), with respect to such Warrant Obligation, the “Incorporated Terms and Provisions”). With respect to each Warrant Obligation, the applicable Incorporated Terms and Provisions are hereby incorporated by reference herein and are deemed to be a part of this Certificate and are binding upon the parties hereto as though fully set forth herein as of the applicable issue date, original issue date or other date for original issuance of such Warrant Obligation as specified on Schedule 1 hereto and in the Applicable Pricing Supplement (such date, the “Original Issue Date”); provided, however, for the avoidance of doubt, no hypothetical examples, risk factors, historical information, descriptions of Underlying Market Measures (as defined in the Warrant Agreement) or other information not considered to be terms or provisions of such Warrant Obligation provided or incorporated by reference in the Incorporated Terms and Provisions shall be used to determine the terms of this Certificate or such Warrant Obligation. Each reference to “this Certificate” includes and shall be deemed to refer to each Warrant Obligation. For certain Warrant Obligations, the supplement in which the specific terms and provisions are described may be referred to as a “term sheet” rather than a “pricing supplement”. As used herein, with respect to any such Warrant Obligation, the term “pricing supplement” also refers to any such “term sheet.” The Applicable Pricing Supplement with respect to each Warrant Obligation is on file with and identified in the records of the Warrant Agent.

Any payments due on each Warrant Obligation evidenced by this Certificate are fully and unconditionally guaranteed by Bank of America Corporation as more fully set forth in the Warrant Agreement.

With respect to each Warrant Obligation, every term and provision of this Certificate is subject to modification, amendment or elimination through the incorporation by reference of the applicable Incorporated Terms and Provisions, whether or not the phrase “unless otherwise provided in the Incorporated Terms and Provisions” or language of similar import precedes the term of this Certificate so modified, amended or eliminated. With respect to each Warrant Obligation, it is the intent of the parties hereto that, in the case of any conflict, inconsistency or difference

2

between the terms and provisions of such Warrant Obligation as set forth herein and as set forth in the applicable Incorporated Terms and Provisions, the terms and provisions in the Incorporated Terms and Provisions shall control over and shall modify the terms and provisions herein to the extent of such conflict, inconsistency or difference. In the event any Incorporated Terms and Provisions set forth in the Applicable Pricing Supplement relating to a Warrant Obligation modify, differ from or conflict or are inconsistent with terms and provisions in the Prospectus, Prospectus Supplement or any Additional Incorporated Supplement, the terms and provisions in the Applicable Pricing Supplement will govern and control to the extent of such conflict, inconsistency or difference. In addition, in the event any Incorporated Terms and Provisions set forth in an Additional Incorporated Supplement relating to a Warrant Obligation modify, differ from or conflict or are inconsistent with the terms and provisions in the Prospectus or Prospectus Supplement, the terms and provisions in such Additional Incorporated Supplement will govern and control to the extent of such conflict, inconsistency or difference, as provided therein, unless otherwise provided in the Applicable Pricing Supplement relating to such Warrant Obligation. Without limiting the foregoing, in the case of each Warrant Obligation, holders of beneficial interests in this Certificate are directed to the applicable Incorporated Terms and Provisions for a description of terms and provisions of such Warrant Obligation.

This Certificate certifies that, with respect to each Warrant Obligation represented hereby, CEDE & CO., as nominee for The Depository Trust Company, or its registered assigns, is the holder of the number of applicable Warrants set forth on Schedule 1 hereto and/or, as applicable, the applicable records of the Warrant Agent (including the Warrant Register), as adjusted in accordance with Schedule 1 hereto and/or, as applicable, such other records of the Warrant Agent, to reflect any repurchases and cancellations in accordance with the Warrant Agreement. Upon valid exercise (or automatic exercise, if applicable) of the Warrants comprising a Warrant Obligation in accordance with the terms and provisions thereof set forth in the applicable Incorporated Terms and Provisions, each Warrant entitles the holder of this Certificate to receive from the Issuer the amount, if any, payable in cash, determined or calculated as set forth in such Incorporated Terms and Provisions, on the date set forth in such Incorporated Terms and Provisions and subject to the terms and provisions specified herein and in the Incorporated Terms and Provisions.

Any amounts payable on a Warrant Obligation following exercise of the applicable Warrants, in each case in accordance with the terms and provisions thereof, will be paid to the person in whose name this Certificate is registered at the time of payment by the applicable Paying Agent (as defined in the Warrant Agreement) in respect of such Warrant Obligation. Payments of amounts payable, if any, on any Warrant Obligation shall be made in U.S. dollars by wire transfer to the registered holder of this Certificate, without necessity of presentation or surrender of this Certificate for exercise, to such account as has been appropriately designated to the Paying Agent by the person entitled to such payments. Neither the holder of this Certificate nor any Warrantholder shall be entitled under the terms of this Certificate or any Warrant Obligation to receive, in payment hereof or thereof, any property other than cash. Following the applicable date on which either (1) all amounts (if any) due and payable on any applicable Warrant Obligation have been duly paid in accordance with the terms and provisions thereof, this Certificate and the Warrant Agreement or (2) the Warrants comprising such Warrant Obligation have expired with no payments coming due, the Warrant Agent, in its capacity as Warrant Registrar, shall promptly note the cancellation of such Warrants by notation on Schedule 1 hereto and/or, as applicable, the applicable

3

records of the Warrant Agent (including the Warrant Register). Neither this Certificate nor any Warrant Obligation represented hereby shall entitle the holder hereof or any Warrantholder of any such Warrant Obligation to any of the rights of a holder or beneficial owner of any Underlying Market Measure(s) by reference to which amounts that may become due and payable on such Warrant Obligation are to be calculated or determined, including, without limitation, the right to receive the payment of any dividends or distributions on such Underlying Market Measure(s) or to vote or to enforce any rights under any documents governing such Underlying Market Measure(s).

The Company will pay any administrative costs imposed by any bank in making payments in immediately available funds, but any tax, assessment or governmental charge imposed upon payments hereunder, including, without limitation, any withholding tax, will be borne by the holder hereof.

Reference is made to the further terms and provisions of this Certificate set forth on the reverse hereof and the applicable terms and provisions set forth in the applicable Incorporated Terms and Provisions with respect to each Warrant Obligation, which terms and provisions shall have the same effect as though fully set forth herein. References herein to “this Certificate,” “hereof,” “herein” and comparable terms shall mean this Certificate and, with respect to each Warrant Obligation, shall include the applicable terms and provisions set forth in the applicable Incorporated Terms and Provisions.

Unless this Certificate has been countersigned by the Warrant Agent by manual or electronic signature of an authorized signatory, this Certificate shall not be entitled to any benefit under the Warrant Agreement or be valid or obligatory for any purpose.

In the event the Company or the Guarantor, or any of their affiliates (as such term is defined in, and interpreted in accordance with, 12 U.S.C. 1841(k)), becomes subject to a proceeding under U.S. Special Resolution Regime, default rights against the Company or the Guarantor with respect to the Relevant Agreements are permitted to be exercised to no greater extent than such default rights could be exercised under such U.S. Special Resolution Regime if the Relevant Agreements were governed by the laws of the United States or a state of the United States.
