Investor Considerations

The Securities are not appropriate for all investors. The Securities may be an appropriate investment for investors who:

■ seek a fixed return equal to the Call Premium if the securities are automatically called on the Call Date;

■ if the Securities are not automatically called, seek 150% leveraged exposure to the upside performance of the Underlying Stock if the Ending Price is greater than the Starting Price;

■ are willing to accept the risk that, if the Securities are not automatically called and the Ending Price is less than the Threshold Price, they will be fully exposed to the decrease in the price of the Underlying Stock and will lose more than 40%, and possibly all, of the principal amount per Security at maturity;

■ understand that the term of the Securities may be as short as approximately one year if the Securities are called on the Call Date;

■ understand and are willing to accept the full downside risks of the Underlying Stock;

■ are willing to forgo interest payments on the Securities and dividends on the Underlying Stock; and

■ are willing to hold the Securities until maturity.

The Securities may not be an appropriate investment for investors who:

■ seek a liquid investment or are unable or unwilling to hold the Securities to maturity;

■ require full payment of the principal amount of the Securities at maturity;

■ seek a security with a fixed term;

■ are unwilling to accept the risk that, if the stock closing price of the Underlying Stock is less than the Starting Price on both the Call Date and the Final Calculation Day, they will not receive any positive return on their investment in the Securities;

■ are unwilling to accept the risk that the stock closing price of the Underlying Stock may decrease by more 40% from the Starting Price to the Ending Price;

■ are unwilling to purchase Securities with an estimated value as of the Pricing Date that is lower than the public offering price set forth on the cover page of this pricing supplement;

■ seek current income;

■ are unwilling to accept the risk of exposure to the Underlying Stock;

■ seek exposure to the Underlying Stock but are unwilling to accept the risk/return trade-offs inherent in the Maturity Payment Amount for the Securities;

■ are unwilling to accept the credit risk of BofA Finance, as issuer, and BAC, as guarantor, to obtain exposure to the Underlying Stock generally, or to obtain exposure to the Underlying Stock that the Securities provide specifically; or

■ prefer the lower risk of conventional fixed income investments with comparable maturities issued by companies with comparable credit ratings.

The considerations identified above are not exhaustive. Whether or not the Securities are an appropriate investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the appropriateness of an investment in the Securities in light of your particular circumstances. You should also review carefully "Selected Risk Considerations" herein and "Risk Factors" in each of the accompanying product supplement, prospectus supplement and prospectus for risks related to an investment in the Securities. For more information about the Underlying Stock, please see the section titled "The Common Stock of Intel Corporation" below.

PS-8

Selected Risk Considerations

The Securities have complex features and investing in the Securities will involve risks not associated with an investment in conventional debt securities. Your decision to purchase the Securities should be made only after carefully considering the risks of an investment in the Securities, including those discussed below, with your advisors in light of your particular circumstances. The Securities are not an appropriate investment for you if you are not knowledgeable about significant elements of the Securities or financial matters in general. You should carefully review the more detailed explanation of risks relating to the Securities in the "Risk Factors" sections beginning on page PS-5 of the accompanying product supplement, page S-6 of the accompanying prospectus supplement and page 7 of the accompanying prospectus.

Structure-related Risks

Your investment may result in a loss; there is no guaranteed return of principal. There is no fixed principal repayment amount on the Securities at maturity. If the Securities are not automatically called prior to maturity and the Ending Price of the Underlying Stock is less than the Threshold Price, at maturity, you will lose 1% of the principal amount for each 1% that the Ending Price of the Underlying Stock is less than the Starting Price. In that case, you will lose a significant portion or all of your investment in the Securities.

The Securities do not bear interest.Unlike a conventional debt security, no interest payments will be paid over the term of the Securities, regardless of the extent to which the stock closing price of the Underlying Stock exceeds the Starting Price or Threshold Price on the Call Date or the Final Calculation Day, as applicable.

If the Securities are automatically called, your return will be limited to the Call Premium. If the Securities are automatically called, the positive return on the Securities will be limited to the Call Premium, and you will not participate in any appreciation of the Underlying Stock beyond the Call Premium, which may be significant. Accordingly, if the Securities are automatically called, the return on the Securities may be less than the return in a direct investment in the Underlying Stock. If the Securities are automatically called, you will not have the opportunity to participate in any appreciation of the Underlying Stock at the Upside Participation Rate.

The amount payable upon an automatic call or the Maturity Payment Amount, as applicable, will not reflect the price of the Underlying Stock other than on the Call Date or the Final Calculation Day, as applicable. The prices of the Underlying Stock during the term of the Securities other than on the Call Date or the Final Calculation Day, as applicable, will not affect payments on the Securities. Notwithstanding the foregoing, investors should generally be aware of the performance of the Underlying Stock while holding the Securities, as the performance of the Underlying Stock may influence the market value of the Securities. The calculation agent will determine whether the Securities will be automatically called, and will calculate the amount payable upon an automatic call or the Maturity Payment Amount, as applicable, by comparing only the Starting Price or Threshold Price, as applicable, to the stock closing price of the Underlying Stock on the Call Date or the Final Calculation Day, as applicable. No other prices of the Underlying Stock will be taken into account. As a result, if the Securities are not automatically called, and the Ending Price of the Underlying Stock is less than the Threshold Price, you will receive less than the principal amount at maturity even if the price of the Underlying Stock was always above the Threshold Price prior to the Final Calculation Day.

The Securities are subject to a potential automatic call, which would limit your ability to receive further payment on the Securities. The Securities are subject to a potential automatic call. The Securities will be automatically called if, on the Call Date, the stock closing price of the Underlying Stock is greater than or equal to the Starting Price. If the Securities are automatically called, you will be entitled to receive the principal amount and the Call Premium, and no further amounts will be payable with respect to the Securities. If the Securities are called, you may be unable to invest in other securities with a similar level of risk that could provide a return that is similar to the Securities.

Your return on the Securities may be less than the yield on a conventional debt security of comparable maturity. Any return that you receive on the Securities may be less than the return you would earn if you purchased a conventional debt security with the same Maturity Date. As a result, your investment in the Securities may not reflect the full opportunity cost to you when you consider factors, such as inflation, that affect the time value of money.

The Call Settlement Date or the Maturity Date may be postponed if the Call Date or the Final Calculation Day is postponed. The Call Date or Final Calculation Day with respect to the Underlying Stock will be postponed if the applicable originally scheduled Call Date or Final Calculation Day is not a trading day with respect to the Underlying Stock or if the calculation agent determines that a market disruption event has occurred or is continuing with respect to the Underlying Stock on the Call Date or Final Calculation Day. If such a postponement occurs with respect to the Call Date, then the Call Settlement Date will be postponed. If such a postponement occurs with respect to the Final Calculation Day, the Maturity Date will be the later of (i) the initial Maturity Date and (ii) three business days after the Final Calculation Day as postponed.

PS-9

Any payment on the Securities is subject to our credit risk and the credit risk of the Guarantor, and actual or perceived changes in our or the Guarantor's creditworthiness are expected to affect the value of the Securities. The Securities are our senior unsecured debt securities. Any payment on the Securities will be fully and unconditionally guaranteed by the Guarantor. The Securities are not guaranteed by any entity other than the Guarantor. As a result, your receipt of the payment upon automatic call or the Maturity Payment Amount at maturity, as applicable, will be dependent upon our ability and the ability of the Guarantor to repay our respective obligations under the Securities on the applicable payment date, regardless of the stock closing price of the Underlying Stock as compared to the Starting Price or Threshold Price, as applicable. No assurance can be given as to what our financial condition or the financial condition of the Guarantor will be at any time after the Pricing Date of the Securities. If we and the Guarantor become unable to meet our respective financial obligations as they become due, you may not receive the amount(s) payable under the terms of the Securities.

In addition, our credit ratings and the credit ratings of the Guarantor are assessments by ratings agencies of our respective abilities to pay our obligations. Consequently, our or the Guarantor's perceived creditworthiness and actual or anticipated decreases in our or the Guarantor's credit ratings or increases in the spread between the yield on our respective securities and the yield on U.S. Treasury securities (the "credit spread") prior to the Maturity Date of your Securities may adversely affect the market value of the Securities. However, because your return on the Securities depends upon factors in addition to our ability and the ability of the Guarantor to pay our respective obligations, such as the price of the Underlying Stock, an improvement in our or the Guarantor's credit ratings will not reduce the other investment risks related to the Securities.

We are a finance subsidiary and, as such, have no independent assets, operations or revenues. We are a finance subsidiary of the Guarantor, have no operations other than those related to the issuance, administration and repayment of our debt securities that are guaranteed by the Guarantor, and are dependent upon the Guarantor and/or its other subsidiaries to meet our obligations under the Securities in the ordinary course. Therefore, our ability to make payments on the Securities may be limited.

Valuation- and Market-related Risks

The public offering price you are paying for the Securities exceeds their initial estimated value. The initial estimated value of the Securities that is provided on the cover page of this pricing supplement is an estimate only, determined as of the Pricing Date by reference to our and our affiliates' pricing models. These pricing models consider certain assumptions and variables, including our credit spreads and those of the Guarantor, the Guarantor's internal funding rate, mid-market terms on hedging transactions, expectations on interest rates, dividends and volatility, price-sensitivity analysis, and the expected term of the Securities. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. If you attempt to sell the Securities prior to maturity, their market value may be lower than the price you paid for them and lower than their initial estimated value. This is due to, among other things, changes in the price of the Underlying Stock, changes in the Guarantor's internal funding rate, and the inclusion in the public offering price of the underwriting discount and the hedging related charges, all as further described in "Structuring the Securities" below. These factors, together with various credit, market and economic factors over the term of the Securities, are expected to reduce the price at which you may be able to sell the Securities in any secondary market and will affect the value of the Securities in complex and unpredictable ways.

The initial estimated value does not represent a minimum or maximum price at which we, BAC, BofAS or any of our other affiliates or WFS or its affiliates would be willing to purchase your Securities in any secondary market (if any exists) at any time. The value of your Securities at any time after issuance will vary based on many factors that cannot be predicted with accuracy, including the performance of the Underlying Stock, our and BAC's creditworthiness and changes in market conditions.

We cannot assure you that a trading market for your Securities will ever develop or be maintained. We will not list the Securities on any securities exchange. We cannot predict how the Securities will trade in any secondary market or whether that market will be liquid or illiquid.

The Securities are not designed to be short-term trading instruments, and if you attempt to sell the Securities prior to maturity, their market value, if any, will be affected by various factors that interrelate in complex ways, and their market value may be less than the principal amount. The following factors are expected to affect the value of the Securities: price of the Underlying Stock at such time; volatility of the Underlying Stock; economic and other conditions generally; interest rates; dividend yields; our and the Guarantor's financial condition and creditworthiness; and time to maturity.

Conflict-related Risks

Trading and hedging activities by us, the Guarantor and any of our other affiliates, including BofAS, and WFS and its affiliates, may create conflicts of interest with you and may affect your return on the Securities and their market value. We, the Guarantor or one or more of our other affiliates, including BofAS, and WFS and its affiliates, may buy or sell shares of the Underlying Stock, or futures or options contracts on the Underlying Stock, or other listed or over-the-counter derivative instruments linked to the Underlying Stock. While we, the Guarantor or one or more of our other affiliates, including BofAS, and WFS and its affiliates, may from time to time own shares of the Underlying Stock, we, the Guarantor and our other affiliates, including BofAS, and WFS and its affiliates, do

PS-10

not control the issuer of the Underlying Stock (the "Underlying Stock Issuer"), and have not verified any disclosure made by the Underlying Stock Issuer or any other company. We, the Guarantor or one or more of our other affiliates, including BofAS, or WFS and its affiliates, may execute such purchases or sales for our own or their own accounts, for business reasons, or in connection with hedging our obligations under the Securities. These transactions may present a conflict of interest between your interest in the Securities and the interests we, the Guarantor and our other affiliates, including BofAS, and WFS and its affiliates, may have in our or their proprietary accounts, in facilitating transactions, including block trades, for our or their other customers, and in accounts under our or their management. These transactions may adversely affect the price of the Underlying Stock in a manner that could be adverse to your investment in the Securities. On or before the Pricing Date, any purchases or sales by us, the Guarantor or our other affiliates, including BofAS or others on its behalf, and WFS and its affiliates (including for the purpose of hedging some or all of our anticipated exposure in connection with the Securities), may have affected the price of the Underlying Stock. Consequently, the price of the Underlying Stock may change subsequent to the Pricing Date, which may adversely affect the market value of the Securities.

We, the Guarantor or one or more of our other affiliates, including BofAS, and WFS and its affiliates, also may have engaged in hedging activities that could have affected the price of the Underlying Stock on the Pricing Date. In addition, these hedging activities, including the unwinding of a hedge, may decrease the market value of your Securities prior to maturity, and may affect the amounts to be paid on the Securities. We, the Guarantor or one or more of our other affiliates, including BofAS, and WFS and its affiliates, may purchase or otherwise acquire a long or short position in the Securities and may hold or resell the Securities. For example, BofAS may enter into these transactions in connection with any market making activities in which it engages. We cannot assure you that these activities will not adversely affect the price of the Underlying Stock, the market value of your Securities prior to maturity or the amounts payable on the Securities.

If WFS, BofAS or an affiliate of either selling agent participating as a dealer in the distribution of the Securities conducts hedging activities for us in connection with the Securities, such selling agent or participating dealer will expect to realize a projected profit from such hedging activities, and this projected profit will be in addition to any discount, concession or fee received in connection with the sale of the Securities to you. This additional projected profit may create a further incentive for the selling agents or participating dealers to sell the Securities to you.

There may be potential conflicts of interest involving the calculation agent, which is an affiliate of ours. We have the right to appoint and remove the calculation agent. One of our affiliates will be the calculation agent for the Securities and, as such, will make a variety of determinations relating to the Securities, including the amounts that will be paid on the Securities. Under some circumstances, these duties could result in a conflict of interest between its status as our affiliate and its responsibilities as calculation agent.

Underlying-related Risks

Any payments on the Securities and whether the Securities are automatically called will depend upon the performance of the Underlying Stock, and therefore the Securities are subject to the following risks, each as discussed in more detail in the accompanying product supplement.

Tax-related Risks

The U.S. federal income and estate tax consequences of the Securities are uncertain, and may be adverse to a holder of the Securities. See "U.S. Federal Income Tax Summary" below and "U.S. Federal Income Tax Summary" beginning on page PS-36 of the accompanying product supplement.

PS-11

Hypothetical Examples and Returns

The payout profile, hypothetical returns and examples below illustrate hypothetical payments upon automatic call or at maturity for a $1,000 principal amount security on a hypothetical offering of securities under various scenarios, with the assumptions set forth in the table below. The terms used for purposes of these hypothetical examples do not represent the actual Starting Price or Threshold Price of the Underlying Stock. The hypothetical Starting Price of 100.00 for the Underlying Stock has been chosen for illustrative purposes only and does not represent the actual Starting Price of the Underlying Stock. The actual Starting Price and Threshold Price for the Underlying Stock are set forth under "Terms of the Securities" above. For historical data regarding the actual stock closing prices of the Underlying Stock, see the historical information set forth herein. The payout profile, return table and examples below assume that an investor purchases the Securities for $1,000 per Security. These examples are for purposes of illustration only and the values used in the examples may have been rounded for ease of analysis. The actual amount you receive at maturity or upon automatic call and the resulting pre-tax total rate of return will depend on the actual terms of the Securities.

Hypothetical Payout Profile

PS-12

Hypothetical Returns

If the Securities are automatically called:

If the Securities are automatically called on the Call Date, on the Call Settlement Date you will receive the principal amount of your Securities plus the Call Premium, resulting in a hypothetical pre-tax total rate of return of 24.05%.

If the Securities are not automatically called:

Hypothetical Examples Of Payment Upon Automatic Call Or At Maturity

Example 1. The stock closing price of the Underlying Stock on the Call Date is greater than the Starting Price, and the Securities are automatically called on the Call Date:

Because the hypothetical stock closing price of the Underlying Stock on the Call Date is greater than the hypothetical Starting Price, the Securities are automatically called on the Call Date and you will receive on the Call Settlement Date the principal amount of your Securities plus a Call Premium of 24.05% of the principal amount. Even though the Underlying Stock appreciated by 25.00% from the Starting Price to its stock closing price on the Call Date in this example, your return is limited to the Call Premium of 24.05%.

On the Call Settlement Date, you would receive $1,240.50 per Security.

PS-13

Example 2. The Securities are not automatically called. The Ending Price is greater than the Starting Price and the Maturity Payment Amount is greater than the principal amount of your Securities:

Because the hypothetical stock closing price of the Underlying Stock on the Call Date is less than the hypothetical Starting Price, the Securities are not automatically called. Because the hypothetical Ending Price is greater than the hypothetical Starting Price, the Maturity Payment Amount per Security would be equal to the principal amount of $1,000 plus a positive return equal to:

$1,000 × Underlying Stock Return × Upside Participation Rate

$1,000 × 20.00% × 150.00%

= $300.00

On the Maturity Date, you would receive $1,300.00 per Security.

Example 3. The Securities are not automatically called. The Ending Price is less than the Starting Price but greater than the Threshold Price and the Maturity Payment Amount is equal to the principal amount of your Securities:

Because the hypothetical stock closing price of the Underlying Stock on the Call Date is less than the hypothetical Starting Price, the Securities are not automatically called. Because the hypothetical Ending Price is less than the hypothetical Starting Price, but not by more than 40%, you would receive the principal amount of your Securities at maturity.

On the Maturity Date, you would receive $1,000.00 per Security.

Example 4. The Securities are not automatically called. The Ending Price is less than the Threshold Price and the Maturity Payment Amount is less than the principal amount:

PS-14

Because the hypothetical stock closing price of the Underlying Stock on the Call Date is less than the hypothetical Starting Price, the Securities are not automatically called. Because the hypothetical Ending Price is less than the hypothetical Starting Price by more than 40%, you would lose a portion of the principal amount of your Securities and would be paid a Maturity Payment Amount equal to:

$1,000 + ($1,000 × Underlying Stock Return)

$1,000 + ($1,000 × -50.00%)

= $500.00

On the Maturity Date, you would receive $500.00 per Security, resulting in a loss of 50.00%.

PS-15

All disclosures contained in this pricing supplement regarding the Underlying Stock and the Underlying Stock Issuer have been derived from publicly available sources. Because the Underlying Stock is registered under the Securities Exchange Act of 1934, the Underlying Stock Issuer is required to periodically file certain financial and other information specified by the Securities and Exchange Commission (SEC). Information provided to or filed with the SEC by the Underlying Stock Issuer can be located through the SEC's website at sec.gov by reference to the CIK number set forth below. This document relates only to the offering of the Securities and does not relate to any offering of Underlying Stock or any other securities of the Underlying Stock Issuer. None of us, the Guarantor, BofAS or any of our other affiliates has made any due diligence inquiry with respect to the Underlying Stock Issuer in connection with the offering of the Securities. 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 Stock Issuer 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 Stock, have been or will be publicly disclosed. Subsequent disclosure of any events or the disclosure of or failure to disclose material future events concerning the Underlying Stock Issue could affect the price of the Underlying Stock and therefore could affect your return on the Securities. The selection of the Underlying Stock is not a recommendation to buy or sell the Underlying Stock.

None of us, the Guarantor, BofAS or any of our other affiliates makes any representation to you as to the future performance of the Underlying Stock. You should make your own investigation into the Underlying Stock.

Historical Information

The following graph sets forth the daily historical performance of INTC in the period from January 2, 2020 through the Pricing Date. We obtained this historical data from Bloomberg L.P. We have not independently verified the accuracy or completeness of the information obtained from Bloomberg L.P. The horizontal line in the graph represents INTC's Threshold Price of $14.766, which is 60% of INTC's Starting Price of $24.61.

This historical data on INTC is not necessarily indicative of the future performance of INTC or what the value of the Securities may be. Any historical upward or downward trend in the price of INTC during any period set forth above is not an indication that the price of INTC is more or less likely to increase or decrease at any time over the term of the Securities.

Before investing in the Securities, you should consult publicly available sources for the trading pattern and prices of INTC.

PS-16

Structuring the Securities

The Securities are our debt securities, the return on which is linked to the performance of the Underlying Stock. The related guarantee is BAC's obligation. Any payments on the Securities, including payment of the Maturity Payment Amount, depend on the credit risk of BofA Finance and BAC and on the performance of the Underlying Stock. As is the case for all of our and BAC's respective debt securities, including our market-linked securities, the economic terms of the Securities reflect our and BAC's actual or perceived creditworthiness at the time of pricing. In addition, because market-linked securities result in increased operational, funding and liability management costs to us and BAC, BAC typically borrows the funds under these types of securities 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 Securities, along with the fees and charges associated with market-linked securities, resulted in the initial estimated value of the Securities on the Pricing Date being less than their public offering price.

The initial estimated value of the Securities as of the Pricing Date is set forth on the cover page of this pricing supplement.

In order to meet our payment obligations on the Securities, at the time we issue the Securities, 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 Stock, the tenor of the Securities and the hedging arrangements. The economic terms of the Securities 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.

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 Securities (the "Master Note") identifying the Securities offered hereby as supplemental obligations thereunder in accordance with the instructions of BofA Finance, and the Securities 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 Securities and the related guarantee, such Securities 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 Securities and due authentication of the Master Note, the validity, binding nature and enforceability of the indenture governing the Securities 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

You should consider the U.S. federal income and estate tax consequences of an investment in the Securities, including the following:

You should consult your own tax advisor concerning the U.S. federal income tax consequences to you of acquiring, owning, and disposing of the Securities, 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. You should review carefully the discussion under the section entitled "U.S. Federal Income Tax Summary" beginning on page PS-36 of the accompanying product supplement.
