Any payments on the Notes depend on the credit risk of BofA Finance, as Issuer, and BAC, as Guarantor, and on the performance of the Underlying Stocks. The economic terms of the Notes are based on BAC's internal funding rate, which is the rate it would pay to borrow funds through the issuance of market-linked notes, and the economic terms of certain related hedging arrangements BAC's affiliates enter into BAC's internal funding rate is typically lower than the rate it would pay when it issues conventional fixed or floating rate debt securities. This difference in funding rate, as well as the underwriting discount, if any, and the hedging related charges described below (see "Risk Factors" beginning on page PS-13), reduced the economic terms of the Notes to you and the initial estimated value of the Notes. Due to these factors, the public offering price you are paying to purchase the Notes is greater than the initial estimated value of the Notes as of the pricing date.

The initial estimated value of the Notes as of the pricing date is set forth on the cover page of this pricing supplement. For more information about the initial estimated value and the structuring of the Notes, see "Risk Factors" beginning on page PS-13 and "Structuring the Notes" on page PS-21.

Total Contingent Coupon Payment Examples

The table below illustrates the hypothetical total Contingent Coupon Payments per $1,000.00 in principal amount of Notes over the term of the Notes, based on the Contingent Coupon Payment of $5.417, depending on how many Contingent Coupon Payments are payable prior to an Automatic Call or maturity. Depending on the performance of the Underlying Stocks, you may not receive any Contingent Coupon Payments during the term of the Notes.

Hypothetical Payout Profile and Examples of Payments at Maturity

Contingent Income Auto-Callable Yield Notes Table

The following table is for purposes of illustration only. It assumes the Notes have not been automatically called prior to maturity and is based on hypothetical values and shows hypothetical returns on the Notes. The table illustrates the calculation of the Redemption Amount and the return on the Notes based on a hypothetical Starting Value of 100 for the Least Performing Underlying Stock, a hypothetical Coupon Barrier of 80 for the Least Performing Underlying Stock, the Contingent Coupon Payment of $5.417 per $1,000.00 in principal amount of Notes and a range of hypothetical Ending Values of the Least Performing Underlying Stock. The actual amount you receive and the resulting return will depend on the actual Starting Values, Coupon Barriers, Observation Values and Ending Values of the Underlying Stocks, whether the Notes are automatically called prior to maturity, and whether you hold the Notes to maturity. The following examples do not take into account any tax consequences from investing in the Notes.

For recent actual values of the Underlying Stocks, see "The Underlying Stocks" section below. The Ending Value of each Underlying Stock will not include any income generated by dividends or other distributions paid with respect to shares of that Underlying Stock. In addition, all payments on the Notes are subject to Issuer and Guarantor credit risk.

The Underlying Stocks

We have derived the following information on each Underlying Stock and each company issuing an Underlying Stock (each, an "Underlying Company" and, together, the "Underlying Companies") from publicly available documents. Because each Underlying Stock is registered under the Securities Exchange Act of 1934, the Underlying Companies are required to file periodically certain financial and other information specified by the SEC. Information provided to or filed with the SEC by the Underlying Companies can be located through the SEC's web site at sec.gov by reference to the applicable CIK number set forth below.

This document relates only to the offering of the Notes and does not relate to any offering of Underlying Stock or any other securities of the Underlying Companies. None of us, the Guarantor, BofAS or any of our other affiliates has made any due diligence inquiry with respect to the Underlying Companies in connection with the offering of the Notes. None of us, the Guarantor, BofAS or any of our other affiliates has independently verified the accuracy or completeness of the publicly available documents or any other publicly available information regarding the Underlying Companies and hence makes no representation regarding the same. Furthermore, there can be no assurance that all events occurring prior to the date of this document, including events that would affect the accuracy or completeness of these publicly available documents that could affect the trading price of the Underlying Stocks, have been or will be publicly disclosed. Subsequent disclosure of any events or the disclosure of or failure to disclose material future events concerning an Underlying Company could affect the price of the applicable Underlying Stock and therefore could affect your return on the Notes. The selection of the Underlying Stocks is not a recommendation to buy or sell the Underlying Stocks.

Supplement to the Plan of Distribution; Role of BofAS and Conflicts of Interest

BofAS, a broker-dealer affiliate of ours, is a member of the Financial Industry Regulatory Authority, Inc. ("FINRA") and will participate as selling agent in the distribution of the Notes. Accordingly, the offering of the Notes will conform to the requirements of FINRA Rule 5121. BofAS may not make sales in this offering to any of its discretionary accounts without the prior written approval of the account holder.

We will deliver the Notes against payment therefor in New York, New York on a date that is greater than one business day following the pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes more than one business day prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

Under our distribution agreement with BofAS, BofAS will purchase the Notes from us as principal at the public offering price indicated on the cover of this pricing supplement, less the indicated underwriting discount, if any. BofAS will sell the Notes to other broker-dealers that will participate in the offering and that are not affiliated with us, at an agreed discount to the principal amount. Each of those broker-dealers may sell the Notes to one or more additional broker-dealers. BofAS has informed us that these discounts may vary from dealer to dealer and that not all dealers will purchase or repurchase the Notes at the same discount. Certain dealers who purchase the Notes for sale to certain fee-based advisory accounts may forgo some or all of their selling concessions, fees or commissions. The public offering price for investors purchasing the Notes in these fee-based advisory accounts may be as low as $958.75 per $1,000.00 in principal amount of Notes.

BofAS and any of our other broker-dealer affiliates may use this pricing supplement and the accompanying product supplement, prospectus supplement and prospectus for offers and sales in secondary market transactions and market-making transactions in the Notes. However, they are not obligated to engage in such secondary market transactions and/or market-making transactions. These broker-dealer affiliates may act as principal or agent in these transactions, and any such sales will be made at prices related to prevailing market conditions at the time of the sale.

At BofAS's discretion, for a short, undetermined initial period after the issuance of the Notes, BofAS may offer to buy the Notes in the secondary market at a price that may exceed the initial estimated value of the Notes. Any price offered by BofAS for the Notes will be based on then-prevailing market conditions and other considerations, including the performance of the Underlying Stocks and the remaining term of the Notes. However, none of us, the Guarantor, BofAS or any of our other affiliates is obligated to purchase your Notes at any price or at any time, and we cannot assure you that any party will purchase your Notes at a price that equals or exceeds the initial estimated value of the Notes.

Any price that BofAS may pay to repurchase the Notes will depend upon then prevailing market conditions, the creditworthiness of us and the Guarantor, and transaction costs. At certain times, this price may be higher than or lower than the initial estimated value of the Notes.

European Economic Area and United Kingdom

None of this pricing supplement, the accompanying product supplement, the accompanying prospectus or the accompanying prospectus supplement is a prospectus for the purposes of the Prospectus Regulation (as defined below). This pricing supplement, the accompanying product supplement, the accompanying prospectus and the accompanying prospectus supplement have been prepared on the basis that any offer of Notes in any Member State of the European Economic Area (the "EEA") or in the United Kingdom (each, a "Relevant State") will only be made to a legal entity which is a qualified investor under the Prospectus Regulation ("Qualified Investors"). Accordingly any person making or intending to make an offer in that Relevant State of Notes which are the subject of the offering contemplated in this pricing supplement, the accompanying product supplement, the accompanying prospectus and the accompanying prospectus supplement may only do so with respect to Qualified Investors. Neither BofA Finance nor BAC has authorized, nor does it authorize, the making of any offer of Notes other than to Qualified Investors. The expression "Prospectus Regulation" means Regulation (EU) 2017/1129.

PROHIBITION OF SALES TO EEA AND UNITED KINGDOM RETAIL INVESTORS - The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA or in the United Kingdom. For these purposes: (a) a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU, as amended ("MiFID II"); or (ii) a customer within the meaning of Directive (EU) 2016/97 (the Insurance Distribution Directive) where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Regulation; and (b) the expression "offer" includes the communication in any form and by any means of sufficient information on the terms of the offer and the Notes to be offered so as to enable an investor to decide to purchase or subscribe for the Notes. Consequently no key information document required by Regulation (EU) No 1286/2014, as amended (the "PRIIPs Regulation") for offering or selling the Notes or otherwise making them available to retail investors in the EEA or in the United Kingdom has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA or in the United Kingdom may be unlawful under the PRIIPs Regulation.

United Kingdom

The communication of this pricing supplement, the accompanying product supplement, the accompanying prospectus supplement, the accompanying prospectus and any other document or materials relating to the issue of the Notes offered hereby is not being made, and such documents and/or

Contingent Income Auto-Callable Yield Notes Linked to the Least Performing of the Class C Capital Stock of Alphabet Inc., the Common Stock of Citigroup Inc. and the Common Stock of Costco Wholesale Corporation

materials have not been approved, by an authorized person for the purposes of Section 21 of the United Kingdom's Financial Services and Markets Act 2000, as amended (the "FSMA"). Accordingly, such documents and/or materials are not being distributed to, and must not be passed on to, the general public in the United Kingdom. The communication of such documents and/or materials as a financial promotion is only being made to those persons in the United Kingdom who have professional experience in matters relating to investments and who fall within the definition of investment professionals (as defined in Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005, as amended (the "Financial Promotion Order")), or who fall within Article 49(2)(a) to (d) of the Financial Promotion Order, or who are any other persons to whom it may otherwise lawfully be made under the Financial Promotion Order (all such persons together being referred to as "Relevant Persons"). In the United Kingdom, the Notes offered hereby are only available to, and any investment or investment activity to which this pricing supplement, the accompanying product supplement, the accompanying prospectus supplement and the accompanying prospectus relates will be engaged in only with, Relevant Persons. Any person in the United Kingdom that is not a relevant person should not act or rely on this pricing supplement, the accompanying product supplement, the accompanying prospectus supplement or the accompanying prospectus or any of their contents.

Any invitation or inducement to engage in investment activity (within the meaning of Section 21 of the FSMA) in connection with the issue or sale of the Notes may only be communicated or caused to be communicated in circumstances in which Section 21(1) of the FSMA does not apply to BofA Finance, as Issuer, or BAC, as Guarantor.

All applicable provisions of the FSMA must be complied with in respect to anything done by any person in relation to the Notes in, from or otherwise involving the United Kingdom.

Structuring the Notes

The Notes are our debt securities, the return on which is linked to the performance of the Underlying Stocks. The related guarantee is BAC's obligation. As is the case for all of our and BAC's respective debt securities, including our market-linked notes, the economic terms of the Notes reflect our and BAC's actual or perceived creditworthiness at the time of pricing. In addition, because market-linked notes result in increased operational, funding and liability management costs to us and BAC, BAC typically borrows the funds under these types of notes at a rate, which we refer to in this pricing supplement as BAC's internal funding rate, that is more favorable to BAC than the rate that it might pay for a conventional fixed or floating rate debt security. This generally relatively lower internal funding rate, which is reflected in the economic terms of the Notes, along with the fees and charges associated with market-linked notes, resulted in the initial estimated value of the Notes on the pricing date being less than their public offering price.

In order to meet our payment obligations on the Notes, at the time we issue the Notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with BofAS or one of our other affiliates. The terms of these hedging arrangements are determined based upon terms provided by BofAS and its affiliates, and take into account a number of factors, including our and BAC's creditworthiness, interest rate movements, the volatility of the Underlying Stocks, the tenor of the Notes and the hedging arrangements. The economic terms of the Notes and their initial estimated value depend in part on the terms of these hedging arrangements.

BofAS has advised us that the hedging arrangements will include hedging related charges, reflecting the costs associated with, and our affiliates' profit earned from, these hedging arrangements. Since hedging entails risk and may be influenced by unpredictable market forces, actual profits or losses from these hedging transactions may be more or less than any expected amounts.

For further information, see "Risk Factors" beginning on page PS-5 and "Supplemental Use of Proceeds" on page PS-18 of the accompanying product supplement.

Validity of the Notes

In the opinion of McGuireWoods LLP, as counsel to BofA Finance, as issuer, and BAC, as guarantor, when the trustee has made the appropriate entries or notations on Schedule 1 to the master global note that represents the Notes (the "Master Note") identifying the Notes offered hereby as supplemental obligations thereunder in accordance with the instructions of BofA Finance, and the Notes have been delivered against payment therefor as contemplated in this pricing supplement and the related prospectus, prospectus supplement and product supplement, all in accordance with the provisions of the indenture governing the Notes and the related guarantee, such Notes will be the legal, valid and binding obligations of BofA Finance, and the related guarantee will be the legal, valid and binding obligation of BAC, subject, in each case, to the effects of applicable bankruptcy, insolvency (including laws relating to preferences, fraudulent transfers and equitable subordination), reorganization, moratorium and other similar laws affecting creditors' rights generally, and to general principles of equity. This opinion is given as of the date of this pricing supplement and is limited to the Delaware General Corporation Law and the Delaware Limited Liability Company Act (including the statutory provisions, all applicable provisions of the Delaware Constitution and reported judicial decisions interpreting either of the foregoing) and the laws of the State of New York as in effect on the date hereof. In addition, this opinion is subject to customary assumptions about the trustee's authorization, execution and delivery of the indenture governing the Notes and due authentication of the Master Note, the validity, binding nature and enforceability of the indenture governing the Notes and the related guarantee with respect to the trustee, the legal capacity of individuals, the genuineness of signatures, the authenticity of all documents submitted to McGuireWoods LLP as originals, the conformity to original documents of all documents submitted to McGuireWoods LLP as copies thereof, the authenticity of the originals of such copies and certain factual matters, all as stated in the opinion letter of McGuireWoods LLP dated December 8, 2022, which has been filed as an exhibit to the Registration Statement (File Nos. 333-268718 and 333-268718-01) of BAC and BofA Finance, filed with the SEC on December 8, 2022.

U.S. Federal Income Tax Summary

The following summary of the material U.S. federal income tax considerations of the acquisition, ownership, and disposition of the Notes is based upon the advice of Sidley Austin LLP, our tax counsel. The following discussion supplements, and to the extent inconsistent supersedes, the discussion under "U.S. Federal Income Tax Considerations" in the accompanying prospectus and is not exhaustive of all possible tax considerations. This summary is based upon the Internal Revenue Code of 1986, as amended (the "Code"), regulations promulgated under the Code by the U.S. Treasury Department ("Treasury") (including proposed and temporary regulations), rulings, current administrative interpretations and official pronouncements of the IRS, and judicial decisions, all as currently in effect and all of which are subject to differing interpretations or to change, possibly with retroactive effect. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax consequences described below. This summary does not include any description of the tax laws of any state or local governments, or of any foreign government, that may be applicable to a particular holder.

Although the Notes are issued by us, they will be treated as if they were issued by BAC for U.S. federal income tax purposes. Accordingly throughout this tax discussion, references to "we," "our" or "us" are generally to BAC unless the context requires otherwise.

This summary is directed solely to U.S. Holders and Non-U.S. Holders that, except as otherwise specifically noted, will purchase the Notes upon original issuance and will hold the Notes as capital assets within the meaning of Section 1221 of the Code, which generally means property held for investment, and that are not excluded from the discussion under "U.S. Federal Income Tax Considerations" in the accompanying prospectus. This discussion does not address the tax consequences applicable to holders subject to Section 451(b) of the Code. This summary assumes that the issue price of the Notes, as determined for U.S. federal income tax purposes, equals the principal amount thereof.

You should consult your own tax advisor concerning the U.S. federal income tax consequences to you of acquiring, owning, and disposing of the Notes, as well as any tax consequences arising under the laws of any state, local, foreign, or other tax jurisdiction and the possible effects of changes in U.S. federal or other tax laws.

U.S. Holders

The tax treatment of your Notes is uncertain. The tax treatment of your Notes will depend upon whether the Notes are properly treated as variable rate debt instruments or contingent payment debt instruments. This in turn depends, in part, upon whether it is reasonably expected that the return on the Notes during the first half of the Notes' term will be significantly greater or less than the return on the Notes during the second half of the Notes' term. Based on our numerical analysis, we intend to take the position that it is not reasonably expected that the return on the Notes during the first half of the Notes' term will be significantly greater or less than the return on the Notes during the second half of the Notes' term. We accordingly intend to treat your Notes as variable rate debt instruments for U.S. federal income tax purposes.

Except as otherwise noted below under "Alternative Tax Treatments," the discussion below assumes that the Notes will be treated as variable rate debt instruments for U.S. federal income tax purposes. Under this characterization, interest on a Note generally will be included in the income of a U.S. Holder as ordinary income at the time it is accrued or is received in accordance with the U.S. Holder's regular method of accounting for U.S. federal income tax purposes. Please see the discussion in the prospectus under the section entitled "U.S. Federal Income Tax Considerations-General-Consequences to U.S. Holders-Variable Rate Debt Securities" for a discussion of these rules.

Upon the sale, exchange, redemption, retirement, or other disposition of a Note, a U.S. Holder will recognize gain or loss equal to the difference between the amount realized upon the sale, exchange, redemption, retirement, or other disposition (less an amount equal to any accrued interest not previously included in income if the Note is disposed of between interest payment dates, which will be included in income as interest income for U.S. federal income tax purposes) and the U.S. Holder's adjusted tax basis in the Note. A U.S. Holder's adjusted tax basis in a Note generally will be the cost of the Note to such U.S. Holder. Any gain or loss realized on the sale, exchange, redemption, retirement, or other disposition of a Note generally will be capital gain or loss and will be long-term capital gain or loss if the Note has been held for more than one year. The ability of U.S. Holders to deduct capital losses is subject to limitations under the Code.

Alternative Tax Treatments. If it is determined that it is reasonably expected that the return on the Notes during the first half of the Notes' term will be significantly greater or less than the return on the Notes during the second half of the Notes' term, the Notes should be treated as a debt instrument subject to special rules governing contingent payment debt instruments for U.S. federal income tax purposes. If the Notes are so treated, a U.S. Holder would be required to accrue original issue discount every year at a "comparable yield" determined at the time of issuance. In addition, you would be required to construct a projected payment schedule for the Notes and you would make a "positive adjustment" to the extent of any excess of an actual payment over the corresponding projected payment under the Notes, and you would make a "negative adjustment" to the extent of the excess of any projected payment over the corresponding actual payment under the Notes. Any gain realized by a U.S. Holder at maturity or upon a sale, exchange, or redemption of the Notes generally would be treated as ordinary income, and any loss realized at maturity or upon a sale, exchange, or redemption of the

Contingent Income Auto-Callable Yield Notes Linked to the Least Performing of the Class C Capital Stock of Alphabet Inc., the Common Stock of Citigroup Inc. and the Common Stock of Costco Wholesale Corporation

Notes generally would be treated as ordinary loss to the extent of the U.S. Holder's prior accruals of original issue discount, and as capital loss thereafter.

It is also possible that the IRS could determine that the Notes should be subject to special rules for Notes that provide for alternative payment schedules if one of such schedules is significantly more likely than not to occur. If your Notes are subject to those rules, you would generally be required to include the stated interest on your Notes in income as it accrues even if you are otherwise subject to the cash basis method of accounting for tax purposes. The rules for Notes that provide alternative payment schedules if one of such schedules is significantly more likely than not to occur are discussed under "U.S. Federal Income Tax Considerations-General-Consequences to U.S. Holders-Debt Securities Subject to Contingencies" in the accompanying prospectus.

Non-U.S. Holders

Please see the discussion under "U.S. Federal Income Tax Considerations-General-Consequences to Non-U.S. Holders" in the accompanying prospectus for the material U.S. federal income tax consequences that will apply to Non-U.S. Holders of the Notes, except that the following disclosure supplements the discussion in the prospectus.

A "dividend equivalent" payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a Non-U.S. Holder. Under Treasury regulations, payments (including deemed payments) with respect to equity-linked instruments ("ELIs") that are "specified ELIs" may be treated as dividend equivalents if such specified ELIs reference an interest in an "underlying security," which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, IRS guidance provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2027. Based on our determination that the Notes are not delta-one instruments, Non-U.S. Holders should not be subject to withholding on dividend equivalent payments, if any, under the Notes. However, it is possible that the Notes could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Underlying Stocks or the Notes, and following such occurrence the Notes could be treated as subject to withholding on dividend equivalent payments. Non-U.S. Holders that enter, or have entered, into other transactions in respect of the Underlying Stocks or the Notes should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the Notes and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.
