TABLE OF CONTENTS

RISK FACTORS

Your investment in the notes entails significant risks, many of which differ from those of a conventional debt security. Your decision to purchase the notes should be made only after carefully considering the risks of an investment in the notes, including those discussed below, with your advisors in light of your particular circumstances. The notes are not an appropriate investment for you if you are not knowledgeable about significant elements of the notes or financial matters in general. You should carefully review the more detailed explanation of risks relating to the notes in the “Risk Factors” sections beginning on page S-6 of the accompanying prospectus supplement and page 7 of the accompanying prospectus.

Risks Related to the 2y SOFR Swap Rate and 30y SOFR Swap Rate

If the 2y SOFR Swap Rate or 30y SOFR Swap Rate does not appear on the Designated SOFR Swap Rate Page at the specified time, and a SOFR Swap Rate Transition Event and related SOFR Swap Rate Replacement Date have not occurred, the applicable rate will be determined by the calculation agent (which is one of our affiliates) using alternative methods, which will involve the exercise of discretion by the calculation agent.

If the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, does not appear on the Designated SOFR Swap Rate Page at the specified time on an applicable interest determination date (for example, as a result of insufficient liquidity in the underlying applicable SOFR swap contracts market) and a SOFR Swap Rate Transition Event and related SOFR Swap Rate Replacement Date have not occurred with respect to the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, the calculation agent will determine the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, for such applicable interest determination date in its sole discretion, after consulting such sources as it deems comparable to the Designated SOFR Swap Rate Page or to the sources from which the administrator of such rate obtains the swap rate input data used by the administrator to calculate such rate, or any other source or data it determines to be reasonable (including, if applicable, the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, that was most recently published by the administrator of such rate) for the purpose of estimating such rate. This method of determining the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, may result in interest payments on the notes that are higher than, lower than or that do not otherwise correlate over time with the interest payments that would have been made on the notes if the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, had been published in accordance with IBA’s (or any successor administrator’s) usual policies and procedures governing determination and publication of the such rate and appeared on the Designated SOFR Swap Rate Page at the specified time. In addition, in determining the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, in this manner, the calculation agent, will have no obligation to consider your interests as an investor in the notes and may have economic interests that are adverse to your interests.

If a SOFR Swap Rate Transition Event and related SOFR Swap Rate Replacement Date are determined to have occurred with respect to either the 30y SOFR Swap Rate or the 2y SOFR Swap Rate, the SOFR Swap Rate Replacement may not be a suitable replacement for such rate.

If we or the calculation agent (after consulting with us) determines that a SOFR Swap Rate Transition Event and related SOFR Swap Rate Replacement Date have occurred with respect to the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, then the applicable SOFR Swap Rate Replacement will replace the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, for all purposes relating to the notes in respect of such determination on such date and all determinations on all subsequent dates, as described under “Description of the Notes—Interest—Determination of U.S. Dollar SOFR ICE Swap Rate^®” in this pricing supplement. The SOFR Swap Rate Replacement will be the alternate interest rate that has been selected by us or the calculation agent (after consulting with us) as an industry-accepted replacement for the 2y SOFR

Swap Rate or 30y SOFR Swap Rate, as applicable, for U.S. dollar-denominated floating-rate notes at such time, plus the applicable SOFR Swap Rate Replacement Adjustment (if any). If we or the calculation agent (after consulting with us) determines that there is no such replacement rate as of any applicable date of determination, then the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, will be determined by us or the calculation agent (after consulting with us), after consulting such sources as it deems comparable to the Designated SOFR Swap Rate Page or to the sources from which the administrator of such rate obtains the swap rate input data used by the administrator to calculate such rate, or any other source or data it determines to be reasonable (including, if applicable, the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, that was most recently published by the administrator of such rate) for the purpose of estimating such rate. After determination of the SOFR Swap Rate Replacement, interest on the notes no longer will be determined by reference to the applicable 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, but instead will be determined by reference to the applicable SOFR Swap Rate Replacement.

There is no assurance that any SOFR Swap Rate Replacement will be similar to the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, in any respect as it is determined and published by IBA as of the date of this pricing supplement, or that any SOFR Swap Rate Replacement will produce the economic equivalent of the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, as a reference rate for determining the interest rate on the notes or otherwise be a suitable replacement or successor for such rate. In addition, it is possible that, at the time of the occurrence of a SOFR Swap Rate Replacement Event and related SOFR Swap Rate Replacement Date, no industry-accepted interest rate as a replacement for the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, will exist and there may be disagreement regarding the selection of a replacement rate for the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable. Notwithstanding the foregoing, the determination of the SOFR Swap Rate Replacement will become effective without your consent or the consent of any other party. Use of the SOFR Swap Rate Replacement may result in interest payments on the notes that are higher than, lower than or that do not otherwise correlate over time with the interest payments that would have been made on such notes in the absence of a SOFR Swap Rate Transition Event and related SOFR Swap Rate Replacement Date.

In addition, although the applicable swap rate transition provisions set forth in this pricing supplement under set forth under “Description of the Notes—Interest—Determination of U.S. Dollar SOFR ICE Swap Rate^®” provide for a SOFR Swap Rate Replacement Adjustment to be added to the Unadjusted SOFR Swap Rate Replacement, such SOFR Swap Rate Replacement Adjustment may be zero or negative, and there is no guarantee that the SOFR Swap Rate Replacement Adjustment (if any) will make the Unadjusted SOFR Swap Rate Replacement equivalent to the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, as it is calculated and published by IBA as of the date of this pricing supplement.

Structure-related Risks

Your return is limited by the cap on the interest rate. After the first eight quarterly interest periods, the interest rate applicable to any interest period will be variable and will not be greater than 20.00% per annum. Accordingly, if the Spread Differential is greater than zero on any interest determination date during the term of the notes, your return on the notes may not reflect the full extent of the Spread Differential multiplied by 10.

Your return on the notes may be less than the yield on a conventional debt security of comparable maturity. The return that you receive on the notes 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 notes may not reflect the full opportunity cost to you when you consider factors that affect the time value of money.

The notes are subject to early redemption at our option. On each Call Date, at our option, we may redeem your notes in whole, but not in part. Even if we do not exercise our option to redeem your notes, our ability to do so may adversely affect the market value of your notes. It is our sole option whether to redeem your notes prior to maturity on any Call Date and we may or may not exercise this option for any reason. If your notes are redeemed early, you will not have the right to receive any future interest payments that you may otherwise have received. Further, if your notes are redeemed early, you may not be able to reinvest the early redemption payment at a comparable return for a similar level of risk.

After the first eight quarterly interest periods, the interest payable on the notes during any quarterly interest period will not reflect changes in the level of 30y SOFR Swap Rate relative to the 2y SOFR Swap Rate other than on the interest determination dates. After the first eight quarterly interest periods, changes in the level of the 30y SOFR Swap Rate relative to the 2y SOFR Swap Rate during the term of the notes other than on the interest determination dates will not affect the interest payable on the notes. The calculation agent will calculate the interest payable during any quarterly interest period, except for the first eight quarterly interest periods, based on the difference between the 30y SOFR Swap Rate and the 2y SOFR Swap Rate on the interest determination dates. No other levels of the 30y SOFR Swap Rate and the 2y SOFR Swap Rate will be taken into account.

After the first eight quarterly interest periods, the notes will pay interest at a floating rate that may be as low as 0.00% per annum on one or more interest payment dates. The rate at which the notes will bear interest during each quarterly interest period after the first eight quarterly interest periods will depend on the Spread Differential. As a result, the interest payable on the notes will vary with fluctuations in the Spread Differential, subject to the minimum interest rate of 0.00% per annum. It is impossible to predict whether the Spread Differential will rise or fall, or the amount of interest payable on the notes. After the first eight quarterly interest periods, you may receive minimal or no interest for extended periods of time or even throughout the remaining term of the notes. The interest rate that will apply at any time on the notes after the first eight quarterly interest periods may be more or less than other prevailing market interest rates at such time. As a result, the amount of interest you receive on the notes may be less than the return you could earn on other investments.

All payments on the notes are 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 notes. The notes are our senior unsecured debt securities. All payments on the notes will be fully and unconditionally guaranteed by the Guarantor. The notes are not guaranteed by any entity other than the Guarantor. As a result, your receipt of all payments of interest and principal on the notes will be dependent upon our ability and the ability of the Guarantor to repay our respective obligations under the notes on the applicable payment date, regardless of the difference between the 30y SOFR Swap Rate and the 2y SOFR Swap Rate. No assurance can be given as to what our financial condition or the financial condition of the Guarantor will be at any time during the term of the notes or on the maturity date. If we and the Guarantor become unable to meet our respective financial obligations as they become due, you may not receive the amounts payable under the terms of the notes.

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, including our obligations under the notes. 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 the notes may adversely affect the market value of the notes. However, because your return on the notes generally depends upon factors in addition to our ability and the ability of the Guarantor to pay our respective obligations, such as the difference between the 30y SOFR Swap Rate and the 2y SOFR Swap Rate during the term of the notes, an

improvement in our or the Guarantor’s credit ratings will not reduce the other investment risks related to the notes.

We are a finance subsidiary and, as such, have no independent assets, operations or revenues. We are a finance subsidiary of BAC, 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 notes in the ordinary course. However, we will have no assets available for distributions to holders of the notes if they make claims in respect of such notes in a bankruptcy, resolution or similar proceeding. Accordingly, any recoveries by such holders in respect of such claims will be limited to those available under the Guarantor’s guarantee of such notes, and any obligations under that guarantee will rank equally in right of payment with all other unsecured and unsubordinated obligations of the Guarantor, except obligations that are subject to any priorities or preferences by law, and senior in right of payment to the Guarantor’s subordinated obligations. Holders of the notes will have recourse only to a single claim against the Guarantor and its assets under the Guarantor’s guarantee of the notes, and holders of the notes should accordingly assume that in any bankruptcy, resolution or similar proceeding, they would not have priority over, and should be treated equally with, the claims of all other unsecured and unsubordinated obligations of the Guarantor, including claims of holders of unsecured senior debt securities issued by the Guarantor.

The Guarantor’s ability to make payments under its guarantee of the notes will depend upon its receipt of funds from its subsidiaries, and applicable laws and regulations, and actions taken under the Guarantor’s resolution plan, could restrict the ability of its subsidiaries to transfer such funds. The Guarantor is a holding company and conducts substantially all of its operations through its subsidiaries. The Guarantor’s ability to make payments under its guarantee of our payment obligations on the notes depends upon the Guarantor’s receipt from its subsidiaries of dividends and other distributions, loans, advances and other payments. Any inability of these subsidiaries to pay dividends or make payments to the Guarantor may adversely affect the Guarantor’s cash flow and financial condition. Many of these subsidiaries, including bank and broker-dealer subsidiaries, are subject to laws that restrict dividend payments or authorize regulatory bodies to block or reduce the flow of funds from those subsidiaries to the Guarantor or to its other subsidiaries. In addition, the Guarantor’s bank and broker-dealer subsidiaries are subject to restrictions on their ability to lend or transact with affiliates and to minimum regulatory capital and liquidity requirements. Lower earnings in these subsidiaries can reduce the amount of funds available to the Guarantor. Adverse business and economic conditions, including changes in interest and currency exchange rates, illiquidity or volatility in areas where the Guarantor has concentrated credit risk, and a failure in or breach of its operational or security systems or infrastructure, could affect its businesses and results of operations. Intercompany arrangements the Guarantor has entered into in connection with its resolution planning could restrict the amount of funding available to it from its subsidiaries under certain adverse conditions, as described below under “—A resolution under the Guarantor’s preferred single point of entry resolution strategy could materially adversely affect its liquidity and financial condition and its ability to make payments under its guarantee of our payment obligations on the notes.” These restrictions could prevent the Guarantor’s subsidiaries from paying dividends or making other distributions to the Guarantor or otherwise providing funds to the Guarantor that the Guarantor needs in order to make payments under its guarantee of our payment obligations on the notes. Also, the Guarantor’s right to participate in any distribution of assets of any of its subsidiaries upon such subsidiary’s liquidation or otherwise will be subject to the prior claims of creditors of that subsidiary, except to the extent that any of the Guarantor’s claims as a creditor of such subsidiary may be recognized.

A resolution under the Guarantor’s preferred single point of entry resolution strategy could materially adversely affect its liquidity and financial condition and its ability to make payments under its guarantee of our payment obligations on the notes. The Guarantor is required periodically to submit a plan to its primary regulatory authorities describing its

resolution strategy under the U.S. Bankruptcy Code in the event of material financial distress or failure. In the Guarantor’s current plan, its preferred resolution strategy is a single point of entry strategy. This strategy provides that only the Guarantor (the parent holding company) files for resolution under the U.S. Bankruptcy Code and contemplates providing certain key operating subsidiaries with sufficient capital and liquidity to operate through severe stress and to enable such subsidiaries to continue operating or be wound down in a solvent manner following a Guarantor bankruptcy. The Guarantor has entered into intercompany arrangements governing the contribution of capital and liquidity with these key subsidiaries. As part of these arrangements, the Guarantor has transferred most of its assets (and has agreed to transfer additional assets) to a wholly-owned holding company subsidiary in exchange for a subordinated note. Certain of the Guarantor’s remaining assets secure its ongoing obligations under these intercompany arrangements. The wholly-owned holding company subsidiary also has provided a committed line of credit that, in addition to the Guarantor’s cash, dividends and interest payments, including interest payments the Guarantor receives in respect of the subordinated note, may be used to fund the Guarantor’s obligations. These intercompany arrangements include provisions to terminate the line of credit, forgive the subordinated note and require the Guarantor to contribute its remaining financial assets to the wholly-owned holding company subsidiary if the Guarantor’s projected liquidity resources deteriorate so severely that resolution becomes imminent, which could materially and adversely affect the Guarantor’s liquidity and ability to meet its payment obligations, including under its guarantee of our payment obligations on the notes. In addition, the Guarantor’s preferred resolution strategy could result in holders of the notes being in a worse position and suffering greater losses than would have been the case under bankruptcy or other resolution scenarios or plans.

Under Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Financial Reform Act”), when a global systemically important banking organization (“G-SIB”), such as the Guarantor, is in default or danger of default, the Federal Deposit Insurance Corporation (“FDIC”) may be appointed receiver in order to conduct an orderly liquidation of such institution. In the event of such appointment, the FDIC could, among other things, invoke the orderly liquidation authority, instead of the U.S. Bankruptcy Code, if the Secretary of the U.S. Department of Treasury makes certain financial distress and systemic risk determinations. In 2013, the FDIC issued a notice describing its preferred “single point of entry” strategy for resolving a G-SIB. Under this approach, the FDIC could replace the Guarantor with a bridge holding company, which could continue operations and result in an orderly resolution of the underlying bank, but whose equity would be held solely for the benefit of the Guarantor’s creditors. The FDIC’s single point of entry strategy may result in holders of the notes suffering greater losses than would have been the case under a bankruptcy proceeding or a different resolution strategy with respect to payments received under the Guarantors’ guarantee of the notes.

The Guarantor’s obligations under its guarantee of the notes will be structurally subordinated to liabilities of the Guarantor’s subsidiaries. Because the Guarantor is a holding company, its right to participate in any distribution of assets of any subsidiary upon such subsidiary’s liquidation or reorganization or otherwise is subject to the prior claims of creditors of that subsidiary, except to the extent the Guarantor may itself be recognized as a creditor of that subsidiary. As a result, any obligations of the Guarantor under its guarantee of the notes will be structurally subordinated to all existing and future liabilities of the Guarantor’s subsidiaries, and claimants should look only to the assets of the Guarantor for payments under the Guarantor’s guarantee of the notes. Further, creditors of the Guarantor’s subsidiaries recapitalized pursuant to the Guarantor’s resolution plan generally would be entitled to payment of their claims from the assets of the subsidiaries, including the Guarantor’s contributed assets. In addition, any obligations of the Guarantor under its guarantee of the notes will be unsecured and, therefore, in a bankruptcy or similar proceeding, will effectively rank junior to the Guarantor’s secured obligations to the extent of the value of the assets securing such obligations.

Each of BofA Finance LLC and the Guarantor is permitted to sell, convey or transfer all or substantially all of its assets to one or more of the Guarantor’s majority-owned

subsidiaries and, in either such event, such subsidiary or subsidiaries will not be required under the indenture relating to the notes to assume our obligations under the notes or the Guarantor’s obligations under its guarantee of the notes, as the case may be. We and the Guarantor each may sell, convey or transfer all or substantially all of its assets to one or more entities that are direct or indirect majority-owned subsidiaries of the Guarantor in which the Guarantor and/or one or more of its subsidiaries owns more than 50% of the combined voting power, and under the indenture under which the notes will be issued, including the provisions thereof relating to the Guarantor’s guarantee of the notes, such subsidiary or subsidiaries will not be required to assume our obligations under the notes or the Guarantor’s obligations under its guarantee thereof, as the case may be. In either such event, (i) we will remain the sole obligor on the notes and the Guarantor will remain the sole obligor on the guarantee of the notes, as the case may be, (ii) creditors of any such subsidiary or subsidiaries would have additional assets from which to recover on their claims and (iii) obligations of the Guarantor under its guarantee of our notes would be structurally subordinated to creditors of such subsidiary or subsidiaries with respect to such transferred assets. See “Description of Debt Securities of BofA Finance LLC—Limitation on Mergers and Sales of Assets” beginning on page 52 of the accompanying prospectus for more information.

The notes issued by us will not have the benefit of any cross-default or cross-acceleration with other indebtedness of BofA Finance LLC or the Guarantor; events of bankruptcy or insolvency or resolution proceedings relating to the Guarantor and covenant breach by the Guarantor will not constitute an event of default with respect to the notes. The notes issued by us will not have the benefit of any cross-default or cross-acceleration with other indebtedness of BofA Finance LLC or the Guarantor. In addition, events of bankruptcy or insolvency or resolution or similar proceedings relating to the Guarantor will not constitute an event of default with respect to the notes. Furthermore, it will not constitute an event of default with respect to the notes if the guarantee by the Guarantor ceases to be in full force and effect for any reason. Therefore, events of bankruptcy or insolvency or resolution or similar proceedings relating to the Guarantor (in the absence of any such event occurring with respect to us) will not permit the notes to be declared due and payable. In addition, a breach of a covenant by the Guarantor (including, for example, a breach of the Guarantor’s covenants with respect to mergers or the sale of all or substantially all its assets) will not permit the notes to be declared due and payable. The value you receive on the notes may be significantly less than what you otherwise would have received had the notes been declared due and payable immediately upon certain events of bankruptcy or insolvency or resolution or similar proceedings relating to the Guarantor or the breach of a covenant by the Guarantor or upon the Guarantor’s guarantee ceasing to be in full force and effect.

Valuation- and Market-related Risks

The public offering price you pay for the notes will exceed the initial estimated value. The range of initial estimated values of the notes that is provided on the cover page of this preliminary pricing supplement, and the initial estimated value as of the pricing date that will be provided in the final pricing supplement, are each estimates only, determined as of a particular point in time 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, volatility, price-sensitivity analysis, and the expected term of the notes. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect.

The initial estimated value does not represent a minimum or maximum price at which we, the Guarantor, BofA Securities, Inc. (“BofAS”) or any of our other affiliates would be willing to purchase your notes in any secondary market (if any exists) at any time. The value of your notes at any time after the pricing date will vary based on many factors that cannot be predicted with accuracy, including our and the Guarantor’s creditworthiness and changes in market conditions.

If you attempt to sell the notes 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 level of the 30y SOFR Swap Rate and the 2y SOFR Swap Rate, 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 Notes” below. These factors, together with various credit, market and economic factors over the term of the notes, are expected to reduce the price at which you may be able to sell the notes in any secondary market and will affect the value of the notes in complex and unpredictable ways.

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

The development of a trading market for the notes will depend on the Guarantor’s financial performance and other factors, including changes in levels of the Spread Differential. The number of potential buyers of your notes in any secondary market may be limited. We anticipate that the selling agent will act as a market-maker for the notes, but none of us, the Guarantor or the selling agent is required to do so. There is no assurance that any party will be willing to purchase your notes at any price in any secondary market. The selling agent may discontinue its market-making activities as to the notes at any time. To the extent that the selling agent engages in any market-making activities, it may bid for or offer the notes. Any price at which the selling agent may bid for, offer, purchase, or sell any notes may differ from the values determined by pricing models that it may use, whether as a result of dealer discounts, mark-ups, or other transaction costs. These bids, offers, or completed transactions may affect the prices, if any, at which the notes might otherwise trade in the market.

In addition, if at any time the selling agent were to cease acting as a market-maker as to the notes, it is likely that there would be significantly less liquidity in the secondary market. In such a case, the price at which the notes could be sold likely would be lower than if an active market existed.

If you attempt to sell the notes 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 of the notes. Unlike savings accounts, certificates of deposit, and other similar investment products, you have no right to have your notes redeemed prior to maturity. If you wish to liquidate your investment in the notes prior to maturity, your only option would be to sell them. At that time, there may be an illiquid market for your notes or no market at all. Even if you were able to sell your notes, there are many factors outside of our control that may affect their market value, some of which, but not all, are stated below. Some of these factors are interrelated in complex ways. As a result, the effect of any one factor may be offset or magnified by the effect of another factor. These factors may interact with each other in complex and unpredictable ways. The following paragraphs describe the expected impact on the market value of the notes from a change in a specific factor, assuming all other conditions remain constant.

Conflict-related Risks

Our trading and hedging activities, and those of the Guarantor and any of our other affiliates, including BofAS, may create conflicts of interest with you. We, the Guarantor or one or more of our other affiliates, including the selling agent, may engage in trading activities related to one or both of the 30y SOFR Swap Rate and the 2y SOFR Swap Rate that are not for your account or on your behalf. These entities also may issue or underwrite other financial instruments with returns linked to the 30y SOFR Swap Rate and/or the 2y SOFR Swap Rate. These trading and hedging activities may present a conflict of interest between your interest in the notes and the interests we, the Guarantor and our other affiliates, including the selling agent, may have in our proprietary accounts, in facilitating transactions, including block trades, for our or their other customers, and in accounts under our or their management. These trading and other business activities, if they influence the levels of the 30y SOFR Swap Rate and/or the 2y SOFR Swap Rate or secondary trading in your notes, could be adverse to your interests as a beneficial owner of the notes.

We, the Guarantor and one or more of our other affiliates, including BofAS, expect to enter into arrangements or adjust or close out existing transactions to hedge our obligations under the notes. We, the Guarantor, or our other affiliates, including BofAS, also may enter into hedging transactions relating to other notes or instruments that we or they issue, some of which may have returns calculated in a manner related to that of the notes offered hereby. We may enter into such hedging arrangements with one or more of our affiliates. Our affiliates may enter into additional hedging transactions with other parties relating to the notes and the 30y SOFR Swap Rate and/or the 2y SOFR Swap Rate. This hedging activity is expected to result in a profit to those engaging in the hedging activity, which could be more or less than initially expected, but could also result in a loss. Each of these parties will price these hedging transactions with the intent to realize a profit, regardless of whether the value of the notes increases or decreases. Any profit in connection with such hedging activities will be in addition to any other compensation that we, the Guarantor, and our other affiliates, including the selling agent, receive for the sale of the notes, which creates an additional incentive to sell the notes 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, MLCS, will be the calculation agent for the notes and, as such, will determine the amount of interest to be paid on the notes. Under some circumstances, these duties could result in a conflict of interest between MLCS’s status as our affiliate and its responsibilities as calculation agent.

For example, if a SOFR Swap Rate Transition Event and related SOFR Swap Rate Replacement Date are determined to have occurred with respect to the 2y SOFR Swap Rate or 30y SOFR Swap Rate, as applicable, we or the calculation agent (after consulting with us) will determine the SOFR Swap Rate Replacement and the SOFR Swap Rate Replacement Adjustment and will make SOFR Swap Rate Replacement Conforming Changes with respect to, among other things, the determination of interest periods, the timing and frequency of determining rates and making payments of interest and other administrative matters, in connection with the applicable SOFR Swap Rate Replacement as set forth under “Description of the Notes —Floating-Rate Notes—Effect of a of U.S. Dollar SOFR ICE Swap Rate^® Transition Event and Related U.S. Dollar SOFR ICE Swap Rate^® Replacement Date” in the accompanying prospectus supplement. Certain

determinations, decisions and elections with respect to the SOFR Swap Rate Replacement will, or the occurrence or non-occurrence of a SOFR Swap Rate Transition Event and any SOFR Swap Rate Conforming Changes may, require the exercise of discretion and the making of subjective judgments by us or the calculation agent (after consulting with us). Any determination, decision or election made by us or the calculation agent pursuant to the applicable provisions set forth under “Description of the Notes —Floating-Rate Notes—Effect of a of U.S. Dollar SOFR ICE Swap Rate^® Transition Event and Related U.S. Dollar SOFR ICE Swap Rate^® Replacement Date” in the accompanying prospectus supplement will, if made by us, be made in our sole discretion and, if made by the calculation agent, be made after consultation with us and, in each case, will become effective without consent from the holders of the notes or any other party. In making these potentially subjective determinations, the Issuer or its designee may have economic interests that are adverse to your interests as holder of the notes, and none of us, the Guarantor or any of our affiliates will have any obligation to consider your interests as a holder of the notes in taking any action or making any determination, which may adversely affect the return on, value of and market for the notes.

For the reasons discussed above, we or the calculation agent may exercise discretion with respect to significant aspects of the terms and provisions of the notes (including with respect to calculating interest payable on the notes).

Tax-related Risks

The U.S. federal income tax consequences of an investment in the notes are uncertain, and may be adverse to a holder of the notes. No statutory, judicial, or administrative authority directly addresses the characterization of the notes or securities similar to the notes for U.S. federal income tax purposes. As a result, significant aspects of the U.S. federal income tax consequences of an investment in the notes are not certain. We intend to treat the notes as debt instruments for U.S. federal income tax purposes. Accordingly, you should consider the tax consequences of investing in the notes, aspects of which are uncertain. See the section entitled “U.S. Federal Income Tax Summary.”

You may be required to include income on the notes over their term in excess of the quarterly coupon payments based on the comparable yield for the notes. The notes will be considered to be issued with original issue discount. You may be required to include income on the notes over their term in excess of the quarterly coupon payments based on the comparable yield for the notes. You are urged to review the section entitled “U.S. Federal Income Tax Summary” and consult your own tax advisor.

You are urged to consult with your own tax advisor regarding all aspects of the U.S. federal income tax consequences of investing in the notes.

DESCRIPTION OF THE NOTES

General

The terms and provisions of the notes are set forth in this pricing supplement and, as applicable, the accompanying prospectus supplement and prospectus. The notes will be part of a series of our medium-term notes entitled “Senior Medium-Term Notes, Series A” issued under the senior indenture, as amended and supplemented from time to time, among us, the Guarantor and The Bank of New York Mellon Trust Company N.A., as trustee. The senior indenture is described more fully in the accompanying prospectus supplement and prospectus. The following description of the notes supplements the description of the general terms and provisions of the notes and debt securities set forth under the headings “Description of the Notes” in the prospectus supplement and “Description of Debt Securities of BofA Finance LLC” in the prospectus. These documents should be read in connection with this pricing supplement.

Our payment obligations on the notes are fully and unconditionally guaranteed by the Guarantor. The notes will rank equally in right of payment with all of our other unsecured and unsubordinated obligations from time to time outstanding, except obligations that are subject to any priorities or preferences by law. The guarantee of the notes will rank equally in right of payment with all other unsecured and unsubordinated obligations of the Guarantor, except obligations that are subject to any priorities or preferences by law, and senior to its subordinated obligations. Any payments due on the notes, including any repayment of principal, are subject to our credit risk, as issuer, and the credit risk of BAC, as guarantor.

The notes will be issued in minimum denominations of $1,000, and whole multiples of $1,000. You may transfer the notes only in whole multiples of $1,000. Unless earlier redeemed, the notes will mature on October 24, 2030.

We may redeem all of the notes on any quarterly interest payment date occurring on or after October 24, 2024 (other than the maturity date). Prior to maturity, the notes are not repayable at your option. The notes are not subject to any sinking fund.

If any scheduled interest payment date, Call Date or the maturity date is not a business day, no adjustment will be made to the length of the corresponding quarterly interest period. The payment will be postponed to the next business day, and no additional interest will be payable as a result of such postponement.

The notes will be issued in book-entry form only.

Interest

Interest Payment Dates, Interest Periods, Interest Reset Dates

Each interest payment due for a quarterly interest period will be paid on January 24, April 24, July 24, and October 24 of each year, beginning on January 24, 2024, and ending on the maturity date (such dates, the “interest payment dates”).

Each quarterly interest period (other than the first quarterly interest period from, and including, the original date of issuance of the notes to, but excluding, January 24, 2024) will commence on, and will include, an interest payment date, and will extend to, but will exclude, the next succeeding interest payment date or the maturity date, as applicable.

A “business day” means any day other than a day on which banking institutions in New York, New York are authorized or required by law, regulation, or executive order to close or a day on which transactions in U.S. dollars are not conducted.

The interest rate for each interest period after the first eight quarterly interest periods will be reset on the first day of that interest period, which we refer to as the “interest reset date.” The “interest determination date” for each such interest period will be the second U.S. government securities business day preceding the applicable interest reset date for such interest period. The calculation agent will determine the applicable interest rate for each interest period on the interest determination date. Once determined by the calculation agent, the applicable interest rate for each quarterly interest period will apply from and including the interest reset date, through, but excluding, the next interest reset date (or the maturity date, as applicable).

Determination of Interest by the Calculation Agent

Interest is computed on the basis of a 360-day year of twelve 30-day months.

For each quarterly interest period, the calculation agent will determine the applicable annualized interest rate as follows:

(a)       From and including October 24, 2023, to but excluding October 24, 2025, interest on the notes will accrue at the rate of 9.60% per annum.

(b)       During each subsequent quarterly interest period beginning on October 24, 2025, interest will accrue at a rate per annum equal to:

10 × (30y SOFR Swap Rate –2y SOFR Swap Rate)

In no event will the interest rate applicable to any interest period after the first eight quarterly interest periods be greater than 20.00% per annum or less than 0.00% per annum.

“30y SOFR Swap Rate” means the U.S. Dollar SOFR ICE Swap Rate^® for a tenor of 30 years as of the applicable interest determination date.

“2y SOFR Swap Rate” means the U.S. Dollar SOFR ICE Swap Rate^® for a tenor of 2 years as of the applicable interest determination date.

Early Redemption at Our Option

On any Call Date, we have the right to redeem all, but not less than all, of the notes at the Early Redemption Payment. No further amounts will be payable following an early redemption. We will give notice to the trustee at least five business days but not more than 60 calendar days before the applicable Call Date.

The “Early Redemption Payment” will be the principal amount of your notes, plus any accrued and unpaid interest.

The “Call Dates” will be the quarterly interest payment dates beginning on October 24, 2024 and ending on July 24, 2030.

Payment at Maturity

Unless earlier redeemed, on the maturity date, you will be paid the principal amount of the notes and any accrued and unpaid interest on the notes, subject to our and the Guarantor’s credit risk. See “Risk Factors—Structure-related Risks—All payments on the notes are 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 notes” above.

Regardless of the amounts of the interest payable during each interest period over the term of the notes, you will receive your principal amount at maturity, assuming that we are otherwise able to pay our debts on the maturity date.

Role of the Calculation Agent

The calculation agent has the sole discretion to make all determinations regarding the notes, including determinations regarding the 30y SOFR Swap Rate, the 2y SOFR Swap Rate, the Spread Differential, the amount of each interest payment, U.S. government securities business days, and business days. Absent manifest error, all determinations of the calculation agent will be final and binding on you and us, without any liability on the part of the calculation agent.

We have initially appointed our affiliate, MLCS, as the calculation agent, but we may change the calculation agent at any time without notifying you.

Same-Day Settlement and Payment

The notes will be delivered in book-entry form only through DTC against payment by purchasers of the notes in immediately available funds. We will make payments of the principal amount and each interest payment in immediately available funds so long as the notes are maintained in book-entry form.

Events of Default and Rights of Acceleration

If an Event of Default, as defined in the senior indenture and in the section entitled “Description of Debt Securities of BofA Finance LLC—Events of Default and Rights of Acceleration; Covenant Breaches” on page 54 of the accompanying prospectus, with respect to the notes occurs and is continuing, the amount payable to a holder of the notes upon any acceleration permitted under the senior indenture will be equal to the principal amount plus any accrued and unpaid interest. In case of a default in the payment of the notes, whether at their maturity or upon acceleration, the notes will not bear a default interest rate.

Listing

The notes will not be listed on any securities exchange.

U.S. DOLLAR SOFR ICE SWAP RATE^® AND ITS METHODOLOGY

General

The U.S. Dollar SOFR ICE Swap Rate^® was launched by IBA for use as a benchmark on November 8, 2021 in order to aid the market’s transition to SOFR and away from U.S. dollar LIBOR. IBA is the administrator of the U.S. Dollar SOFR ICE Swap Rate^® and has overall responsibility for all aspects of the U.S. Dollar SOFR ICE Swap Rate^® determination process, including the development, determination, dissemination, operation and governance of the various U.S. Dollar SOFR ICE Swap Rate^® tenors. IBA has published the ICE Swap Rate^® Methodology and certain other applicable policies which together set out IBA’s method for determining and publishing, rules and criteria relating to, and certain other information applicable to the U.S. Dollar SOFR ICE Swap Rate^®. Information in the ICE Swap Rate^® Methodology and IBA’s other applicable policies reflect the policies of, and are subject to change by, IBA. IBA licenses the U.S. Dollar SOFR ICE Swap Rate^® to users for, among other purposes, use as a reference rate. The U.S. Dollar SOFR ICE Swap Rate^® is calculated on each weekday other than those set forth in IBA’s ICE Swap Rate Holiday Calendar, which is available on the ICE Swap Rate^® Website, and published in the ICE Report Center, a link to which is available on the ICE Swap Rate^® Website. For any particular day, the only rate available for viewing on the ICE Report Center is the rate published for the preceding publication day.

Pursuant to the ICE Swap Rate^® Methodology, the U.S. Dollar SOFR ICE Swap Rate^® is calculated using eligible prices and volumes for U.S. dollar swaps referencing a compounded average of daily SOFR compounded in arrears for twelve months using standard market conventions, calculated on the basis of the actual number of days elapsed, with a year presumed to comprise 360 days). Input data for calculation of the U.S. Dollar SOFR ICE Swap Rate^® consists of executable prices and volumes provided by regulated, electronic, trading venues and, if such trading venues do not provide sufficient eligible input data, dealer to client prices and volumes displayed electronically by trading venues. If there is insufficient eligible input data to calculate a rate in accordance with the foregoing, IBA uses movement interpolation, where possible for applicable tenors, to calculate a rate. Where it is not possible to calculate an U.S. Dollar SOFR ICE Swap Rate^® for an applicable tenor in accordance with the foregoing, then IBA’s Insufficient Data Policy will apply and “No Publication” will be published for the U.S. Dollar SOFR ICE Swap Rate^® of the applicable tenor. The U.S. Dollar SOFR ICE Swap Rate^® for the various applicable tenors as reported on the ICE Report Center and the Designated SOFR Swap Rate Page is expressed as an integer; however, for purpose of calculations of interest with respect to the notes, such rate will be deemed to be expressed as a percentage (for example, if the U.S. Dollar SOFR ICE Swap Rate^® is reported on the ICE Report Center and the Designated SOFR Swap Rate Page as 1.24, such rate for purposes of calculations of interest with respect to the notes will be deemed to be 1.24%).

IBA states that: (i) historical U.S. Dollar SOFR ICE Swap Rate^® and other information may not be indicative of future information or performance, (ii) none of IBA, Intercontinental Exchange, Inc. (“ICE”) or any third party that provides data used to administer or determine the U.S. Dollar SOFR ICE Swap Rate^® and other information (“Data Provider”), or any of its or their affiliates, makes any claim, prediction, warranty or representation whatsoever, expressly or impliedly, as to the timeliness, accuracy or completeness of the U.S. Dollar SOFR ICE Swap Rate^® or other information, the results to be obtained from the use of the U.S. Dollar SOFR ICE Swap Rate^® or other information, or as to the appropriateness or suitability of any the U.S. Dollar SOFR ICE Swap Rate^® or other information for any particular purpose to which it might be put, (iii) to the fullest extent permitted by applicable law, none of IBA, ICE or any Data Provider, or any of its or their affiliates will be liable in respect of any inaccuracies, errors, omissions, delays, failures, cessations or changes (material or otherwise) in IBA’s U.S. Dollar SOFR ICE Swap Rate^® and other information, or for any damage, expense or other loss (whether direct or indirect) you may suffer arising out of or in connection with IBA’s U.S. Dollar SOFR ICE Swap Rate^® and other information or any reliance you may place upon it and (iv) all implied terms, conditions and

warranties, including without limitation as to quality, merchantability, fitness for purpose, title or non-infringement, in relation to IBA’s U.S. Dollar SOFR ICE Swap Rate^® and other information are hereby excluded to the fullest extent permitted by applicable law.

Neither the ICE Swap Rate^® Website, other pages to which the ICE Swap Rate^® Website may contain hyperlinks, nor any of the information or materials available thereon, are incorporated by reference into this pricing supplement. Use of the U.S. Dollar SOFR ICE Swap Rate^® is subject to important disclaimers set forth in IBA’s Benchmark and Other Information Notice and Disclaimer, available on the ICE Swap Rate^® Website and in the ICE Swap Rate^® Methodology.

We, BAC, the selling agent and IBA are not affiliated with the New York Fed. The New York Fed does not sanction, endorse, or recommend any products or services offered by us or IBA.

Historical Levels of 30y SOFR Swap Rate and 2y SOFR Swap Rate

The following graph sets forth the historical daily spread (expressed in basis points, where 100 basis points equals 1%) between 30y SOFR Swap Rate and 2y SOFR Swap Rate from November 8, 2021 (the date the U.S. Dollar SOFR ICE Swap Rate^® was launched by IBA for use as a benchmark) through October 6, 2023. This data is not intended to be indicative of the future performance of the difference between 30y SOFR Swap Rate and 2y SOFR Swap Rate or what the value of or return on the notes may be. Any historical upward or downward trend in the difference between 30y SOFR Swap Rate and 2y SOFR Swap Rate during any period set forth below is not an indication that such difference is more or less likely to increase or decrease in value at any time over the term of the notes or that these represent what the difference would have been on any hypothetical interest determination date. The historical month-end spread between 30y SOFR Swap Rate and 2y SOFR Swap Rate below uses 30y SOFR Swap Rate and 2y SOFR Swap Rate as quoted on the Bloomberg Professional Services service on page “USD SOFR (11:15am NY)” for the indices “USISSO02 Index” (in the case of the 2y SOFR Swap Rate) and “USISSO30 Index” (in the case of the 30y SOFR Swap Rate), at the SOFR Swap Rate Reference Time, on the applicable date.

No one can predict what 30y SOFR Swap Rate and/or 2y SOFR Swap Rate will be on any day throughout the life of the notes or what 30y SOFR Swap Rate and/or 2y SOFR Swap Rate will be on any interest determination date. 30y SOFR Swap Rate and 2y SOFR Swap Rate are new benchmarks that were launched by IBA on November 8, 2021. The future performance of 30y SOFR Swap Rate and 2y SOFR Swap Rate and, by extension, the amount payable on and market value for the notes, cannot be predicted based on the limited historical information available. The amount payable on and market value for the notes may be lower and more volatile than a comparable investment where interest payments are determined by reference to a benchmark with more fulsome historical information.

Interest payable on the notes after the first eight quarterly interest periods will be imperfectly correlated to the difference between long-term interest rates (as measured by 30y SOFR Swap Rate) and short-term interest rates (as measured by 2y SOFR Swap Rate). Although long-term interest rates directionally follow short-term interest rates, movements in long-term interest rates generally tend to be smaller than movements in short-term interest rates. As such, when short-term interest rates rise, the difference between 30y SOFR Swap Rate and 2y SOFR Swap Rate tends to narrow (the curve of the spread flattens); conversely, when short-term interest rates fall, the spread widens (the curve of the spread becomes steeper). After the first eight quarterly interest periods, interest payable on the notes will be greater the wider the spread between 30y SOFR Swap Rate and 2y SOFR Swap Rate, and the steeper the curve of the spread, as of each interest determination date.

HYPOTHETICAL EXAMPLES

The following three examples are provided for purposes of illustration only. They should not be taken as an indication or prediction of future investment results and are intended merely to illustrate the impact that the various hypothetical levels of 30y SOFR Swap Rate and 2y SOFR Swap Rate on an interest determination date, set forth below, could have on the annualized interest rate payable on the notes for a quarterly interest period commencing on and after October 24, 2025.

The examples below are based on the spread multiplier of 10 and a range of levels of 30y SOFR Swap Rate and 2y SOFR Swap Rate that are entirely hypothetical; no one can predict what 30y SOFR Swap Rate and/or 2y SOFR Swap Rate will be on any day during the term of the notes or what 30y SOFR Swap Rate and/or 2y SOFR Swap Rate will be on any interest determination date or, by extension, the amount payable on and market value for the notes.

Below are three hypothetical examples of the calculation of the annualized interest rate payable on a quarterly interest payment date occurring on and after October 24, 2025 for the notes. The actual annualized interest rate to be applied in calculating the interest payable on the notes for any quarterly interest period after the first eight quarterly interest periods will depend on the actual levels of 30y SOFR Swap Rate and 2y SOFR Swap Rate and the actual Spread Differential (i.e., 30y SOFR Swap Rate – 2y SOFR Swap Rate) on the applicable interest determination date.

Example 1: The hypothetical 30y SOFR Swap Rate is substantially greater than the hypothetical 2Y SOFR Swap Rate on the interest determination date:

Hypothetical 30y SOFR Swap Rate: 6.10%

Hypothetical 2Y SOFR Swap Rate: 2.00%

10 × (6.10% – 2.00%) = 41.00%

Interest rate payable for that quarterly interest period = 20.00% per annum (the interest rate cannot be greater than 20.00% per annum)

Example 2: The hypothetical 30y SOFR Swap Rate is greater than the hypothetical 2y SOFR Swap Rate on the interest determination date:

Hypothetical 30y SOFR Swap Rate: 3.70%

Hypothetical 2y SOFR Swap Rate: 3.00%

10 × (3.70% – 3.00%) = 7.00%

Interest rate payable for that quarterly interest period = 7.00% per annum

Example 3: The hypothetical 30y SOFR Swap Rate is less than the hypothetical 2y SOFR Swap Rate on the interest determination date:

Hypothetical 30y SOFR Swap Rate: 3.75%

Hypothetical 2y SOFR Swap Rate: 3.95%

10 × (3.75% – 3.95%) = -2.00%

Interest rate payable for that quarterly interest period = 0.00% per annum (the interest rate cannot be less than 0.00% per annum)

SUPPLEMENTAL 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 a selling agent in the distribution of the notes. Accordingly, the offering of the notes will conform to the requirements of FINRA Rule 5121. The selling agent is a party to the distribution agreement described in the “Supplemental Plan of Distribution (Conflicts of Interest)” beginning on page S-54 of the accompanying prospectus supplement.

The selling agent will receive the compensation, if any, set forth on the cover page of this pricing supplement as to the notes sold through its efforts. Certain dealers who purchase the notes for sale to certain fee-based advisory accounts and/or eligible institutional investors may forgo some or all of their selling concessions, fees or commissions. The price to public for investors purchasing the notes in these accounts may be as low as $980.00 (98.00%) per $1,000 in principal amount of the notes. We or one of our affiliates may pay varying selling concessions of up to 2.00% in connection with the distribution of the notes to other registered broker-dealers. If all of the offered notes are not sold on the pricing date at the public offering price, then the selling agent and/or dealers may offer the notes for sale in one or more transactions at an offering price that may be at a premium to the public offering price. These sales may occur at market prices prevailing at the time of sale, at prices related to market prices or at negotiated prices.

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 30y SOFR Swap Rate, the 2y SOFR Swap Rate, the Spread Differential 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 prospectus or the accompanying prospectus supplement is a prospectus for the purposes of the Prospectus Regulation (as defined below). This pricing 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 the United Kingdom which has implemented the Prospectus Regulation (each, a “Relevant Member 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 Member State of notes which are the subject of the offering contemplated in this pricing 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 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 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 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 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 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 30y SOFR Swap Rate relative to the 2y SOFR Swap Rate. The related guarantees are BAC’s obligations. 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, typically results in the initial estimated value of the notes at the time the terms of the notes are set and 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 30y SOFR Swap Rate and 2y SOFR Swap Rate, 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-9 above.

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 supplements, and to the extent inconsistent supersedes, the discussions under “U.S. Federal Income Tax Considerations” in the accompanying prospectus and under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement 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 Internal Revenue Service (“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 Bank of America Corporation for U.S. federal income tax purposes. Accordingly throughout this tax discussion, references to “we,” “our” or “us” are generally to Bank of America Corporation 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 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.

Tax Characterization of the Notes

The notes will be treated as “contingent payment debt instruments” for U.S. federal income tax purposes, subject to taxation under the “noncontingent bond method.” The balance of this discussion assumes that this characterization is proper and will be respected.

U.S. Holders

The notes will be subject to Treasury regulations governing contingent payment debt instruments. Under those regulations, and as further described under “U.S. Federal Income Tax Considerations—General—Consequences to Non-U.S. Holders ” in the accompanying prospectus, a U.S. Holder will be required to report Original Issue Discount (“OID”) or interest income based on a “comparable yield” and a “projected payment schedule,” established by us for determining interest accruals and adjustments with respect to the notes. A U.S. Holder of the notes generally will be required to include in income OID in excess of actual cash payments received for certain taxable years.

The following table is based upon a hypothetical projected payment schedule and a hypothetical comparable yield equal to 6.35% per annum (compounded quarterly). The hypothetical comparable yield is our current estimate of the comparable yield based upon market conditions as of the date of this preliminary pricing supplement. It has been determined by us for purposes of illustrating the application of the Code and the Treasury regulations to the notes as if the notes had been issued on October 24, 2024 and were scheduled to mature on October 24, 2030. This tax accrual table is based upon a hypothetical projected

payment schedule per $1,000.00 principal amount of the notes, which would consist of estimates of the quarterly interest payments and a single principal payment of $1,000.00 at maturity. The following tables are for illustrative purposes only, and we make no representations or predictions as to what the actual amounts of interest payments will be. The actual “projected payment schedule” will be completed on the pricing date, and included in the final pricing supplement.

In addition, we have determined the hypothetical projected payment schedule for the notes as follows:

Sale, Exchange, Redemption or Retirement. Upon a sale, exchange, redemption or retirement of a note prior to maturity, a U.S. Holder generally will recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange, redemption or retirement and that holder’s tax basis in the note. A U.S. Holder’s tax basis in a note generally will equal the cost of that note, increased by the amount of OID previously accrued by the holder for that note (without regard to any positive or negative adjustments) and reduced by the amount of any noncontingent payment and the projected amount of any contingent payment previously made to the holder and, if applicable, increased or decreased by the amount of any positive or negative adjustment that the holder is required to make with respect to the notes under the rules set forth in the accompanying prospectus addressing purchases of notes for an amount that differs from the notes’ adjusted issue price at the time of purchase. A U.S. Holder generally will treat any gain as interest income, and will treat any loss as ordinary loss to the extent of the excess of previous interest inclusions over the total negative adjustments previously taken into account as ordinary losses, and the balance as long-term or

short-term capital loss depending upon the U.S. Holder’s holding period for the note. The deductibility of capital losses by a U.S. Holder is subject to limitations.
