Coupon Payment is payable based upon the levels of the Underlyings during the Observation Period ending on the deemed Final Observation Date; any such final Contingent Coupon Payment will be prorated by the calculation agent to reflect the length of the Observation Period. 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.

Investment Timeline

	Trade Date	The closing level of each Underlying (its Initial Value) is observed, the Contingent Coupon Payment/Contingent Coupon Rate is set and the Coupon Barrier and Downside Threshold for each Underlying are determined.

	Quarterly (callable by the issuer in its sole discretion beginning in December 2021)	If the closing level of each Underlying on each trading day during the applicable Observation Period is greater than or equal to its Coupon Barrier, we will pay you a Contingent Coupon Payment with respect to that Observation Period on the related Coupon Payment Date. However, if the closing level of any Underlying on any trading day during the relevant Observation Period is below its Coupon Barrier, no Contingent Coupon Payment will accrue or be payable on the related Coupon Payment Date. Beginning in December 2021, the issuer may, in its sole discretion, call the Notes in whole, but not in part, on any Coupon Payment Date prior to the Maturity Date upon not less than five (5) business days’ but not more than 60 calendar days’ notice prior to such Coupon Payment Date. If the Notes are called, on the applicable Coupon Payment Date we will pay you a cash payment per $10.00 Stated Principal Amount equal to the Stated Principal Amount plus any Contingent Coupon Payment otherwise due on such Coupon Payment Date. If the Notes are called, no further payments will be made on the Notes.

	Maturity Date (if not previously called)	If the Notes are not called prior to maturity, the Final Value of each Underlying will be observed on the Final Observation Date. If the Final Value of the Least Performing Underlying on the Final Observation Date is greater than or equal to its Downside Threshold, on the Maturity Date we will pay you the Stated Principal Amount plus any Contingent Coupon Payment otherwise due on the Maturity Date. If the Final Value of the Least Performing Underlying on the Final Observation Date is less than its Downside Threshold, on the Maturity Date we will pay you a cash payment that is less than your Stated Principal Amount and may be zero, resulting in a loss that is proportionate to the negative Underlying Return of the Least Performing Underlying, equal to: $10.00 × (1 + Underlying Return of the Least Performing Underlying)

INVESTING IN THE NOTES INVOLVES SIGNIFICANT RISKS. YOU MAY LOSE A SUBSTANTIAL PORTION OR ALL OF YOUR INITIAL INVESTMENT. YOU WILL BE EXPOSED TO THE MARKET RISK OF EACH UNDERLYING AND ANY DECLINE IN THE LEVEL OF ONE UNDERLYING MAY NEGATIVELY AFFECT YOUR RETURN AND WILL NOT BE OFFSET OR MITIGATED BY A LESSER DECLINE OR ANY POTENTIAL INCREASE IN THE LEVEL OF ANY OTHER UNDERLYING. THE CONTINGENT REPAYMENT OF THE STATED PRINCIPAL AMOUNT APPLIES ONLY IF YOU HOLD THE NOTES TO MATURITY OR EARLIER CALL BY THE ISSUER. ANY PAYMENT ON THE NOTES IS SUBJECT TO THE CREDITWORTHINESS OF BOFA FINANCE AND THE GUARANTOR.

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 PS-5 of the accompanying product supplement, page S-5 of the accompanying prospectus supplement and page 7 of the accompanying prospectus identified on page PS-2 above.

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 Notes at maturity. If the Notes are not called prior to maturity and the Final Value of any Underlying is less than its Downside Threshold, at maturity, you will lose 1% of the Stated Principal Amount for each 1% that the Final Value of the Least Performing Underlying is less than its Initial Value. In that case, you will lose a significant portion or all of your investment in the Notes.

♦

The limited downside protection provided by the Downside Threshold applies only at maturity. You should be willing to hold your Notes to maturity. If you are able to sell your Notes in the secondary market prior to a call or maturity, you may have to sell them at a loss relative to your initial investment even if the level of each Underlying at that time is equal to or greater than its Downside Threshold. All payments on the Notes are subject to the credit risk of BofA Finance, as issuer, and BAC, as guarantor.

♦

Your return on the Notes is limited to the return represented by the Contingent Coupon Payments, if any, over the term of the Notes. Your return on the Notes is limited to the Contingent Coupon Payments paid over the term of the Notes, regardless of the extent to which the daily closing level or the Final Value of any Underlying exceeds its Coupon Barrier or Initial Value, as applicable. Similarly, the amount payable at maturity or upon a call will never exceed the sum of the Stated Principal Amount and any applicable Contingent Coupon Payment, regardless of the extent to which the Final Value or the daily closing level of any Underlying exceeds its Initial Value. In contrast, a direct investment in the securities included in one or more of the Underlyings would allow you to receive the benefit of any appreciation in their values. Thus, any return on the Notes will not reflect the return you would realize if you actually owned those securities and received the dividends paid or distributions made on them.

♦

The Notes are subject to a potential early call, which would limit your ability to receive the Contingent Coupon Payments over the full term of the Notes. Beginning in December 2021, on each Coupon Payment Date prior to the Maturity Date, at our option, we may redeem your Notes in whole, but not in part. If the Notes are called prior to the Maturity Date, you will be entitled to receive the Stated Principal Amount plus any Contingent Coupon Payment otherwise due on such Coupon Payment Date. In this case, you will lose the opportunity to continue to receive Contingent Coupon Payments after the date of the early call. If the Notes are called prior to the Maturity Date, 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 Notes. 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 Coupon Payment Date and we may or may not exercise this option for any reason. Because of this, the term of your Notes could be anywhere between three months and 3 years.

It is more likely that we will call the Notes in our sole discretion prior to maturity to the extent that the expected Contingent Coupon Payments payable on the Notes are greater than the coupon that would be payable on other instruments issued by us of comparable maturity, terms and credit rating trading in the market. The greater likelihood of us calling the Notes in that environment increases the risk that you will not be able to reinvest the proceeds from the called Notes in an another investment that provides a similar yield with a similar level of risk. We are less likely to call the Notes prior to maturity when the expected Contingent Coupon Payments payable on the Notes are less than the coupon that would be payable on other comparable instruments issued by us, which includes when the level of any of the Underlyings is less than its Coupon Barrier. Therefore, the Notes are more likely to remain outstanding when the expected Contingent Coupon Payments payable on the Notes are less than what would be payable on other comparable instruments and when your risk of not receiving a coupon is relatively higher.

♦

You may not receive any Contingent Coupon Payments. The Notes do not provide for any regular fixed coupon payments. Investors in the Notes will not necessarily receive any Contingent Coupon Payments on the Notes. If the closing level of any Underlying on any trading day during an Observation Period is below its Coupon Barrier, no Contingent Coupon Payment will accrue or be payable on the related Coupon Payment Date. If the closing level of any Underlying is less than its Coupon Barrier on at least one trading day during each quarterly Observation Period, you will not receive any Contingent Coupon Payments during the term of the Notes, and will not receive a positive return on the Notes.

♦

Your return on the Notes may be less than the yield on a conventional debt security of comparable maturity. Any 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, such as inflation, that affect the time value of money. In addition, if interest rates increase during the term of the Notes, the Contingent Coupon Payment (if any) may be less than the yield on a conventional debt security of comparable maturity.

♦

Any payment on the Notes 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 Notes. The Notes are our senior unsecured debt securities. Any payment on the Notes will be fully and unconditionally guaranteed by the Guarantor. The Notes are not guaranteed by any entity other than

PS-7

the Guarantor. As a result, your receipt of all payments 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 closing level or Final Value, as applicable, of any Underlying as compared to its Coupon Barrier, Downside Threshold or Initial Value, as applicable. No assurance can be given as to what our financial condition or the financial condition of the Guarantor will be 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 and you could lose all of your initial investment.

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 may adversely affect the market value of the Notes. However, because your return on the Notes depends upon factors in addition to our ability and the ability of the Guarantor to pay our respective obligations, such as the values of the Underlyings, 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. Therefore, our ability to make payments on the Notes may be limited.

Valuation- and Market-related Risks

♦

The public offering price you pay for the Notes will exceed their 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 Trade 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, dividends and 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. 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 Underlyings, 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.

♦

The initial estimated value does not represent a minimum or maximum price at which we, BAC, 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 issuance will vary based on many factors that cannot be predicted with accuracy, including the performance of the Underlyings, our and BAC’s creditworthiness and changes in market conditions.

♦

The price of the Notes that may be paid by BofAS in any secondary market (if BofAS makes a market, which it is not required to do), as well as the price which may be reflected on customer account statements, will be higher than the then-current estimated value of the Notes for a limited time period after the Trade Date. As agreed by BofAS and UBS, for approximately a four-month period after the Trade Date, to the extent BofAS offers to buy the Notes in the secondary market, it will do so at a price that will exceed the estimated value of the Notes at that time. The amount of this excess, which represents a portion of the hedging-related charges expected to be realized by BofAS and UBS over the term of the Notes, will decline to zero on a straight line basis over that four-month period. Accordingly, the estimated value of your Notes during this initial four-month period may be lower than the value shown on your customer account statements. Thereafter, if BofAS buys or sells your Notes, it will do so at prices that reflect the estimated value determined by reference to its pricing models at that time. Any price at any time after the Trade Date will be based on then-prevailing market conditions and other considerations, including the performance of the Underlyings and the remaining term of the Notes. However, none of us, the Guarantor, BofAS or any other party 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.

♦	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 the levels of the Underlyings. The number of potential buyers of your Notes in any secondary market may be limited. We anticipate that BofAS will act as a market-maker for the Notes, but none of us, the Guarantor or BofAS 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. BofAS may discontinue its market-making activities as to the Notes at any time. To the extent that BofAS engages in any market-making activities, it may bid for or offer the Notes. Any price at which BofAS 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 BofAS 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.

PS-8

♦

Economic and market factors have affected the terms of the Notes and may affect the market value of the Notes prior to maturity or a call. Because market-linked notes, including the Notes, can be thought of as having a debt component and a derivative component, factors that influence the values of debt instruments and options and other derivatives will also affect the terms and features of the Notes at issuance and the market price of the Notes prior to maturity or a call. These factors include the levels of the Underlyings and the securities included in the Underlyings; the volatility of the Underlyings and the securities included in the Underlyings; the correlation among the Underlyings; the dividend rate paid on the securities included in the Underlyings, if applicable; the time remaining to the maturity of the Notes; interest rates in the markets; geopolitical conditions and economic, financial, political, force majeure and regulatory or judicial events; whether the level of each of the Underlyings is currently or has been less than its Coupon Barrier; the availability of comparable instruments; the creditworthiness of BofA Finance, as issuer, and BAC, as guarantor; and the then current bid-ask spread for the Notes and the factors discussed under “— Trading and hedging activities by us, the Guarantor and any of our other affiliates, including BofAS, and UBS and its affiliates, may create conflicts of interest with you and may affect your return on the Notes and their market value” below. These factors are unpredictable and interrelated and may offset or magnify each other.

♦

Because the Notes are linked to the performance of the least performing among the RTY, the SPX and the NDX, you are exposed to greater risk of receiving no Contingent Coupon Payments or sustaining a significant loss on your investment than if the Notes were linked to just the RTY, just the SPX or just the NDX. The risk that you will not receive any Contingent Coupon Payments and/or lose a significant portion or all of your investment in the Notes is greater if you invest in the Notes as opposed to substantially similar securities that are linked to the performance of just the RTY, just the SPX or just the NDX. With three Underlyings, it is more likely that any Underlying will close below its Coupon Barrier on a trading day during an Observation Period or below its Downside Threshold on the Final Observation Date than if the Notes were linked to only one of the Underlyings, and therefore it is more likely that you will not receive any Contingent Coupon Payments or will receive a Payment at Maturity that is significantly less than the Stated Principal Amount on the Maturity Date.

♦

Greater expected volatility generally indicates an increased risk of loss. Volatility is a measure of the degree of variation in the levels of the Underlyings over a period of time. The greater the expected volatilities of the Underlyings at the time the terms of the Notes are set, the greater the expectation is at that time that you may not receive one or more, or all, Contingent Coupon Payments and that you may lose a significant portion or all of the Stated Principal Amount at maturity. However, the Underlyings’ volatility can change significantly over the term of the Notes and a relatively higher Contingent Coupon Rate and/or a lower Coupon Barrier and/or a lower Downside Threshold may not necessarily indicate that the Notes have a greater likelihood of paying Contingent Coupon Payments or a return of principal at maturity. You should be willing to accept the downside market risk of each Underlying and the potential to lose a significant portion or all of your initial investment.

Conflict-related Risks

♦

Trading and hedging activities by us, the Guarantor and any of our other affiliates, including BofAS, and UBS and its affiliates, may create conflicts of interest with you and may affect your return on the Notes and their market value. We, the Guarantor or one or more of our other affiliates, including BofAS, and UBS and its affiliates, may buy or sell the securities held by or included in the Underlyings, or futures or options contracts on the Underlyings or those securities, or other listed or over-the-counter derivative instruments linked to the Underlyings or those securities. We, the Guarantor or one or more of our other affiliates, including BofAS, and UBS and its affiliates also may issue or underwrite other financial instruments with returns based upon the Underlyings. We 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, and UBS and its affiliates also may enter into hedging transactions relating to other Notes or instruments, some of which may have returns calculated in a manner related to that of the Notes offered hereby. We or UBS may enter into such hedging arrangements with one of our or their affiliates. Our affiliates or their affiliates may enter into additional hedging transactions with other parties relating to the Notes and the Underlyings. 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, or the hedging activity could also result in a loss. We and our affiliates and UBS and its affiliates 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 BofAS, and UBS and its affiliates receive for the sale of the Notes, which creates an additional incentive to sell the Notes to you. While we, the Guarantor or one or more of our other affiliates, including BofAS, and UBS and its affiliates may from time to time own securities represented by the Underlyings, except to the extent that BAC’s or UBS Group AG’s (the parent company of UBS) common stock may be included in the Underlyings, as applicable, we, the Guarantor and our other affiliates, including BofAS, and UBS and its affiliates do not control any company included in the Underlyings, and have not verified any disclosure made by any other company. We, the Guarantor or one or more of our other affiliates, including BofAS, and UBS 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 Notes. The transactions described above may present a conflict of interest between your interest in the Notes and the interests we, the Guarantor and our other affiliates, including BofAS, and UBS 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.

The transactions described above may adversely affect the value of the Underlyings in a manner that could be adverse to your investment in the Notes. On or before the Trade Date, any purchases or sales by us, the Guarantor or our other affiliates, including BofAS or others on its behalf, and UBS and its affiliates (including for the purpose of hedging some or all of our anticipated exposure in connection with the Notes) may affect the value of the Underlyings. Consequently, the value of the Underlyings may change subsequent to the Trade Date, which may adversely affect the market value of the Notes. In addition, these activities may decrease the market value of your Notes prior to maturity, and may affect the amounts to be paid on the Notes. We, the Guarantor or one or more of our other affiliates, including BofAS, and UBS and its affiliates may purchase or otherwise acquire a long or short position in the Notes and may hold or resell the Notes. For example, BofAS may

PS-9

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 value of the Underlyings, the market value of your Notes prior to maturity or the amounts payable on the Notes.

♦

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 Notes and, as such, will make a variety of determinations relating to the Notes, including the amounts that will be paid on the Notes. 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

♦

The publisher of an Underlying may adjust that Underlying in a way that affects its levels, and the publisher has no obligation to consider your interests. The publisher of an Underlying can add, delete, or substitute the components included in that Underlying or make other methodological changes that could change its level. Any of these actions could adversely affect the value of your Notes.

♦

You are exposed to the market risk of each Underlying. Your return on the Notes is not linked to a basket consisting of the Underlyings. Rather, it will be contingent upon the independent performance of each of the RTY, the SPX and the NDX. Unlike an instrument with a return linked to a basket of underlying assets, in which risk is mitigated and diversified among all of the components of the basket, you will be exposed to the risks related to each of the RTY, the SPX and the NDX. Poor performance by any of the Underlyings over the term of the Notes may negatively affect your return and will not be offset or mitigated by positive performance by any other Underlying. To receive a Contingent Coupon Payment for any Observation Period, the closing level of each Underlying on each trading day during the Observation Period must be greater than or equal to its Coupon Barrier. In addition, to receive the contingent repayment of principal at maturity, each Underlying must close at or above its Downside Threshold on the Final Observation Date. Therefore, if the Notes are not called prior to maturity, you may incur a loss proportionate to the negative return of the Least Performing Underlying even if each other Underlying appreciates during the term of the Notes. Accordingly, your investment is subject to the market risk of each Underlying. Additionally, movements in the values of the Underlyings may be correlated or uncorrelated at different times during the term of the Notes, and such correlation (or lack thereof) could have an adverse effect on your return on the Notes. For example, the likelihood that one of the Underlyings will close below its Coupon Barrier on a trading day during an Observation Period or below its Downside Threshold on the Final Observation Date will increase when the movements in the values of the Underlyings are uncorrelated. Thus, if the performance of the Underlyings is not correlated or is negatively correlated, the risk of not receiving a Contingent Coupon Payment and of incurring a significant loss of principal at maturity is greater. In addition, correlation generally decreases for each additional Underlying to which the Notes are linked, resulting in a greater potential of not receiving a Contingent Coupon Payment and for a significant loss of principal at maturity. Although the correlation of the Underlyings’ performance may change over the term of the Notes, the economic terms of the Notes, including the Contingent Coupon Rate, Downside Thresholds and Coupon Barriers, are determined, in part, based on the correlation of the Underlyings’ performance calculated using our and our affiliates' pricing models at the time when the terms of the Notes are finalized. All other things being equal, a higher Contingent Coupon Rate and lower Downside Threshold and Coupon Barrier is generally associated with lower correlation of the Underlyings, which may indicate a greater potential for missed Contingent Coupon Payments and/or a significant loss on your investment at maturity. See “Correlation of the Underlyings” below.

♦

The Notes are subject to the market risk of the Underlyings. The return on the Notes, which may be negative, is directly linked to the performance of the Underlyings and indirectly linked to the value of the securities included in the Underlyings. The level of the Underlyings can rise or fall sharply due to factors specific to the Underlyings and the securities included in the Underlyings and the issuers of such securities, such as stock price volatility, earnings and financial conditions, corporate, industry and regulatory developments, management changes and decisions and other events, as well as general market factors, such as general stock market or commodity market volatility and levels, interest rates and economic and political conditions.

♦

The Notes are subject to risks associated with small-size capitalization companies. The stocks comprising the RTY are issued by companies with small-sized market capitalization. The stock prices of small-size companies may be more volatile than stock prices of large capitalization companies. Small-size capitalization companies may be less able to withstand adverse economic, market, trade and competitive conditions relative to larger companies. Small-size capitalization companies may also be more susceptible to adverse developments related to their products or services.

♦

The Notes are subject to risks associated with foreign securities markets. The NDX includes certain foreign equity securities. You should be aware that investments in securities linked to the value of foreign equity securities involve particular risks. The foreign securities markets comprising the NDX may have less liquidity and may be more volatile than U.S. or other securities markets and market developments may affect foreign markets differently from U.S. or other securities markets. Direct or indirect government intervention to stabilize these foreign securities markets, as well as cross-shareholdings in foreign companies, may affect trading prices and volumes in these markets. Also, there is generally less publicly available information about foreign companies than about those U.S. companies that are subject to the reporting requirements of the SEC, and foreign companies are subject to accounting, auditing and financial reporting standards and requirements that differ from those applicable to U.S. reporting companies. Prices of securities in foreign countries are subject to political, economic, financial and social factors that apply in those geographical regions. These factors, which could negatively affect those securities markets, include the possibility of recent or future changes in a foreign government’s economic and fiscal policies, the possible imposition of, or changes in, currency exchange laws or other laws or restrictions applicable to foreign companies or investments in foreign equity securities and the possibility of fluctuations in the rate of exchange between currencies, the possibility of outbreaks of hostility and political instability and the possibility of natural disaster or adverse public health developments in the region. Moreover, foreign economies may differ favorably or unfavorably from the U.S. economy in important respects such as growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency.

Tax-related Risks

PS-10

♦

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. Under the terms of the Notes, you will have agreed with us to treat the Notes as contingent income-bearing single financial contracts, as described below under “U.S. Federal Income Tax Summary—General.” If the Internal Revenue Service (the “IRS”) were successful in asserting an alternative characterization for the Notes, the timing and character of income, gain or loss with respect to the Notes may differ. No ruling will be requested from the IRS with respect to the Notes and no assurance can be given that the IRS will agree with the statements made in the section entitled “U.S. Federal Income Tax Summary.” 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.

* The hypothetical Contingent Coupon Rate/Contingent Coupon Payment may not represent the actual Contingent Coupon Rate/Contingent Coupon Payment and the hypothetical Initial Values, Coupon Barriers and Downside Thresholds do not represent the actual Initial Values, Coupon Barriers and Downside Thresholds, respectively, applicable to the Underlyings. The actual Contingent Coupon Rate/Contingent Coupon Payment, Initial Values, Coupon Barriers and Downside Thresholds will be determined on the Trade Date. All payments on the Notes are subject to issuer and guarantor credit risk.

Example 1 — Notes are called by us in our sole discretion on the first Coupon Payment Date.

Date	Lowest Closing Level During Applicable Observation Period			Payment (per Note)
Date	Russell 2000^® Index	S&P 500^® Index	NASDAQ-100^® Index
First Observation Period	75.00 (at or above Coupon Barrier)	75.00 (at or above Coupon Barrier)	78.00 (at or above Coupon Barrier)	$10.21625 (Stated Principal Amount plus Contingent Coupon Payment — Notes are called)
			Total Payment:	$10.21625 (2.1625% total return)

Since the Notes are called by us in our sole discretion on the Coupon Payment Date related to the first Observation Period and the closing level of each Underlying on each trading day during the first Observation Period was greater than its Coupon Barrier, we will pay you a total of $10.21625 per Note (equal to the Stated Principal Amount plus the Contingent Coupon Payment) on that Coupon Payment Date, representing a 2.1625% total return on the Notes over the approximately three months the Notes were outstanding before they were called by us in our sole discretion. You will not receive any further payments on the Notes.

PS-12

Example 2 — Notes are NOT called prior to the Maturity Date and the Final Value of the Least Performing Underlying on the Final Observation Date is at or above its Downside Threshold.

Date	Lowest Closing Level During Applicable Observation Period / Final Value on the Final Observation Date			Payment (per Note)
Date	Russell 2000^® Index	S&P 500^® Index	NASDAQ-100^® Index
First to Tenth Observation Periods	various (all at or above Coupon Barrier)	various (all at or above Coupon Barrier)	various (all below Coupon Barrier)	$0.00 (Notes are not called)
Eleventh Observation Period	78.00 (at or above Coupon Barrier)	78.00 (at or above Coupon Barrier)	78.00 (at or above Coupon Barrier)	$0.21625 (Contingent Coupon Payment — Notes are not called)
Final Observation Period	78.00 (at or above Coupon Barrier)	78.00 (at or above Coupon Barrier)	60.00 (below Coupon Barrier)	$0.00 (Not callable)
Final Observation Date	99.00 (at or above Downside Threshold)	99.00 (at or above Downside Threshold)	77.00 (at or above Downside Threshold)*	$10.00 (Stated Principal Amount)
			Total Payment:	$10.21625 (2.1625% total return)

* Denotes Least Performing Underlying

Since the closing level of one Underlying was below its Coupon Barrier on at least one trading day during each of the first through tenth Observation Periods, you will not receive any Contingent Coupon Payments on any of the related Coupon Payment Dates. However, since the closing level of each Underlying on each trading day during the eleventh Observation Period was greater than its Coupon Barrier, we will pay you the applicable Contingent Coupon Payment of $0.21625 per Note on the related Coupon Payment Date.

Because the Final Value of the Least Performing Underlying is greater than its Downside Threshold, we will pay you $10.00 per Note (equal to the Stated Principal Amount) on the Maturity Date. However, because the closing level of one Underlying was below its Coupon Barrier on at least one trading day during the final Observation Period, you will not receive any Contingent Coupon Payment on the Maturity Date. You would have been paid a total of $10.21625 per Note, representing a 2.1625% total return on the Notes over 3 years.

Example 3 — Notes are NOT called prior to the Maturity Date and the Final Value of the Least Performing Underlying on the Final Observation Date is below its Downside Threshold.

Date	Lowest Closing Level During Applicable Observation Period / Final Value on the Final Observation Date			Payment (per Note)
Date	Russell 2000^® Index	S&P 500^® Index	NASDAQ-100^® Index
First to Eleventh Observation Periods	various (all below Coupon Barrier)	various (all below Coupon Barrier)	various (all below Coupon Barrier)	$0.00 (Notes are not called)
Final Observation Period	30.00 (below Coupon Barrier)	85.00 (at or above Coupon Barrier)	85.00 (at or above Coupon Barrier)	$0.00 (Not callable)
Final Observation Date	30.00 (below Downside Threshold)*	87.00 (at or above Downside Threshold)	87.00 (at or above Downside Threshold)	$10.00 × [1 + Underlying Return of the Least Performing Underlying] = $10.00 × [1 + -70.00%] = $10.00 × 0.30 = $3.00 (Payment at Maturity)
			Total Payment:	$3.00 (-70.00% total return)

* Denotes Least Performing Underlying

Since the closing level of at least one Underlying was below its Coupon Barrier on at least one trading day during each Observation Period, including the final Observation Period, no Contingent Coupon Payments are paid on any Coupon Payment Date during the term of the Notes, including the Maturity Date. On the Final Observation Date, the Least Performing Underlying closes below its Downside Threshold. Therefore, at maturity, investors are exposed to the proportionate downside performance of the Least Performing Underlying and you will receive $3.00 per Note, which reflects the percentage decrease of the closing level of the Least Performing Underlying from the Trade Date to the Final Observation Date, representing a -70.00% total return on the Notes over 3 years.

The Russell 2000^® Index

The RTY was developed by Russell Investments (“Russell”) before FTSE International Limited and Russell combined in 2015 to create FTSE Russell, which is wholly owned by London Stock Exchange Group. Additional information on the RTY is available at the following website: http://www.ftserussell.com. No information on that website is deemed to be included or incorporated by reference in this pricing supplement.

Russell began dissemination of the RTY (Bloomberg L.P. index symbol “RTY”) on January 1, 1984. FTSE Russell calculates and publishes the RTY. The RTY was set to 135 as of the close of business on December 31, 1986. The RTY is designed to track the performance of the small capitalization segment of the U.S. equity market. As a subset of the Russell 3000^® Index, the RTY consists of the smallest 2,000 companies included in the Russell 3000^® Index. The Russell 3000^® Index measures the performance of the largest 3,000 U.S. companies, representing approximately 98% of the investable U.S. equity market. The RTY is determined, comprised, and calculated by FTSE Russell without regard to the Notes.

Selection of Stocks Comprising the RTY

All companies eligible for inclusion in the RTY must be classified as a U.S. company under FTSE Russell’s country-assignment methodology. If a company is incorporated, has a stated headquarters location, and trades in the same country (American Depositary Receipts and American Depositary Shares are not eligible), then the company is assigned to its country of incorporation. If any of the three factors are not the same, FTSE Russell defines three Home Country Indicators (“HCIs”): country of incorporation, country of headquarters, and country of the most liquid exchange (as defined by a two-year average daily dollar trading volume) (“ADDTV”) from all exchanges within a country. Using the HCIs, FTSE Russell compares the primary location of the company’s assets with the three HCIs. If the primary location of its assets matches any of the HCIs, then the company is assigned to the primary location of its assets. If there is insufficient information to determine the country in which the company’s assets are primarily located, FTSE Russell will use the country from which the company’s revenues are primarily derived for the comparison with the three HCIs in a similar manner. FTSE Russell uses the average of two years of assets or revenues data to reduce potential turnover. If conclusive country details cannot be derived from assets or revenues data, FTSE Russell will assign the company to the country of its headquarters, which is defined as the address of the company’s principal executive offices, unless that country is a Benefit Driven Incorporation “BDI” country, in which case the company will be assigned to the country of its most liquid stock exchange. BDI countries include: Anguilla, Antigua and Barbuda, Bahamas, Barbados, Belize, Bermuda, Bonaire, British Virgin Islands, Cayman Islands, Channel Islands, Cook Islands, Curacao, Faroe Islands, Gibraltar, Guernsey, Isle of Man, Jersey, Liberia, Marshall Islands, Panama, Saba, Sint Eustatius, Sint Maarten, and Turks and Caicos Islands. For any companies incorporated or headquartered in a U.S. territory, including Puerto Rico, Guam, and U.S. Virgin Islands, a U.S. HCI is assigned.

All securities eligible for inclusion in the RTY must trade on a major U.S. exchange. Stocks must have a closing price at or above $1.00 on their primary exchange on the last trading day in May to be eligible for inclusion during annual reconstitution. However, in order to reduce unnecessary turnover, if an existing member’s closing price is less than $1.00 on the last day of May, it will be considered eligible if the average of the daily closing prices (from its primary exchange) during the month of May is equal to or greater than $1.00. Initial public offerings are added each quarter and must have a closing price at or above $1.00 on the last day of their eligibility period in order to qualify for index inclusion. If an existing stock does not trade on the “rank day” (typically the last trading day in May but a confirmed timetable is announced each spring) but does have a closing price at or above $1.00 on another eligible U.S. exchange, that stock will be eligible for inclusion.

An important criterion used to determine the list of securities eligible for the RTY is total market capitalization, which is defined as the market price as of the last trading day in May for those securities being considered at annual reconstitution times the total number of shares outstanding. Where applicable, common stock, non-restricted exchangeable shares and partnership units/membership interests are used to determine market capitalization. Any other form of shares such as preferred stock, convertible preferred stock, redeemable shares, participating preferred stock, warrants and rights, installment receipts or trust receipts, are excluded from the calculation. If multiple share classes of common stock exist, they are combined. In cases where the common stock share classes act independently of each other (e.g., tracking stocks), each class is considered for inclusion separately. If multiple share classes exist, the pricing vehicle will be designated as the share class with the highest two-year trading volume as of the rank day in May.

Companies with a total market capitalization of less than $30 million are not eligible for the RTY. Similarly, companies with only 5% or less of their shares available in the marketplace are not eligible for the RTY. Royalty trusts, limited liability companies, closed-end investment companies (companies that are required to report Acquired Fund Fees and Expenses, as defined by the SEC, including business development companies), blank check companies, special purpose acquisition companies, and limited partnerships are also ineligible for inclusion. Bulletin board, pink sheets, and over-the-counter (“OTC”) traded securities are not eligible for inclusion. Exchange traded funds and mutual funds are also excluded.

PS-14

Annual reconstitution is a process by which the RTY is completely rebuilt. Based on closing levels of the company’s common stock on its primary exchange on the rank day of May of each year, FTSE Russell reconstitutes the composition of the RTY using the then existing market capitalizations of eligible companies. Reconstitution of the RTY occurs on the last Friday in June or, when the last Friday in June is the 29th or 30th, reconstitution occurs on the prior Friday. In addition, FTSE Russell adds initial public offerings to the RTY on a quarterly basis based on total market capitalization ranking within the market-adjusted capitalization breaks established during the most recent reconstitution. After membership is determined, a security’s shares are adjusted to include only those shares available to the public. This is often referred to as “free float.” The purpose of the adjustment is to exclude from market calculations the capitalization that is not available for purchase and is not part of the investable opportunity set.

Historical Performance of the RTY

The following graph sets forth the daily historical performance of the RTY in the period from January 1, 2008 through September 8, 2021. 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 orange line in the graph represents the RTY’s hypothetical Coupon Barrier of 1,574.808 (rounded to three decimal places), which is 70% of the RTY’s hypothetical Initial Value of 2,249.726, which was the RTY’s closing level on September 8, 2021. The horizontal gray line in the graph represents the RTY’s hypothetical Downside Threshold of 1,462.322 (rounded to three decimal places), which is 65% of the RTY’s hypothetical Initial Value. The actual Initial Value, Coupon Barrier and Downside Threshold will be determined on the Trade Date.

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

Before investing in the Notes, you should consult publicly available sources for the levels of the RTY.

The S&P 500^® Index

The SPX includes a representative sample of 500 companies in leading industries of the U.S. economy. The SPX is intended to provide an indication of the pattern of common stock price movement. The calculation of the level of the SPX is based on the relative value of the aggregate market value of the common stocks of 500 companies as of a particular time compared to the aggregate average market value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943.

The SPX includes companies from eleven main groups: Communication Services; Consumer Discretionary; Consumer Staples; Energy; Financials; Health Care; Industrials; Information Technology; Real Estate; Materials; and Utilities. SPDJI may from time to time, in its sole discretion, add companies to, or delete companies from, the SPX to achieve the objectives stated above.

Company additions to the SPX must have an unadjusted company market capitalization of $8.2 billion or more (an increase from the previous requirement of an unadjusted company market capitalization of $6.1 billion or more).

SPDJI calculates the SPX by reference to the prices of the constituent stocks of the SPX without taking account of the value of dividends paid on those stocks. As a result, the return on the Notes will not reflect the return you would realize if you actually owned the SPX constituent stocks and received the dividends paid on those stocks.

Computation of the SPX

While SPDJI currently employs the following methodology to calculate the SPX, no assurance can be given that SPDJI will not modify or change this methodology in a manner that may affect payments on the Notes.

Historically, the market value of any component stock of the SPX was calculated as the product of the market price per share and the number of then outstanding shares of such component stock. In March 2005, SPDJI began shifting the SPX halfway from a market capitalization weighted formula to a float-adjusted formula, before moving the SPX to full float adjustment on September 16, 2005. SPDJI’s criteria for selecting stocks for the SPX did not change with the shift to float adjustment. However, the adjustment affects each company’s weight in the SPX.

Under float adjustment, the share counts used in calculating the SPX reflect only those shares that are available to investors, not all of a company’s outstanding shares. Float adjustment excludes shares that are closely held by control groups, other publicly traded companies or government agencies.

In September 2012, all shareholdings representing more than 5% of a stock’s outstanding shares, other than holdings by “block owners,” were removed from the float for purposes of calculating the SPX. Generally, these “control holders” will include officers and directors, private equity, venture capital and special equity firms, other publicly traded companies that hold shares for control, strategic partners, holders of restricted shares, ESOPs, employee and family trusts, foundations associated with the company, holders of unlisted share classes of stock, government entities at all levels (other than government retirement/pension funds) and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. However, holdings by block owners, such as depositary banks, pension funds, mutual funds and ETF providers, 401(k) plans of the company, government retirement/pension funds, investment funds of insurance companies, asset managers and investment funds, independent foundations and savings and investment plans, will ordinarily be considered part of the float.

Treasury stock, stock options, restricted shares, equity participation units, warrants, preferred stock, convertible stock, and rights are not part of the float. Shares held in a trust to allow investors in countries outside the country of domicile, such as depositary shares and Canadian exchangeable shares are normally part of the float unless those shares form a control block. If a company has multiple classes of stock outstanding, shares in an unlisted or non-traded class are treated as a control block.

For each stock, an investable weight factor (“IWF”) is calculated by dividing the available float shares by the total shares outstanding. Available float shares are defined as the total shares outstanding less shares held by control holders. This calculation is subject to a 5% minimum threshold for control blocks. For example, if a company’s officers and directors hold 3% of the company’s shares, and no other control group holds 5% of the company’s shares, SPDJI would assign that company an IWF of 1.00, as no control group meets the 5% threshold. However, if a company’s officers and directors hold 3% of the company’s shares and another control group holds 20% of the company’s shares, SPDJI would assign an IWF of 0.77, reflecting the fact that 23% of the company’s outstanding shares are considered to be held for control. As of July 31, 2017, companies with multiple share class lines are no longer eligible for inclusion in the SPX. Constituents of the SPX prior to July 31, 2017 with multiple share class lines will be grandfathered in and continue to be included in the SPX. If a constituent company of the SPX reorganizes into a multiple share class line structure, that company will remain in the SPX at the discretion of the S&P Index Committee in order to minimize turnover.

The SPX is calculated using a base-weighted aggregate methodology. The level of the SPX reflects the total market value of all component stocks relative to the base period of the years 1941 through 1943. An indexed number is used to represent the results of this calculation in order to make the level easier to work with and track over time. The actual total market value of the component stocks during the base period of the years 1941 through 1943 has been set to an indexed level of 10. This is often indicated by the notation 1941- 43 = 10. In practice, the daily calculation of the SPX is computed by dividing the total market value of the component stocks by the “index divisor.” By itself, the index divisor is an arbitrary number. However, in the context of the calculation of the SPX, it serves as a link to the original base period level of the SPX. The index divisor keeps the SPX comparable over time and is the manipulation point for all adjustments to the SPX, which is index maintenance.

PS-16

Index Maintenance

Index maintenance includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends, and stock price adjustments due to company restructuring or spinoffs. Some corporate actions, such as stock splits and stock dividends, require changes in the common shares outstanding and the stock prices of the companies in the SPX, and do not require index divisor adjustments.

To prevent the level of the SPX from changing due to corporate actions, corporate actions which affect the total market value of the SPX require an index divisor adjustment. By adjusting the index divisor for the change in market value, the level of the SPX remains constant and does not reflect the corporate actions of individual companies in the SPX. Index divisor adjustments are made after the close of trading and after the calculation of the SPX closing level.

Changes in a company’s shares outstanding of 5.00% or more due to mergers, acquisitions, public offerings, tender offers, Dutch auctions, or exchange offers are made as soon as reasonably possible. Share changes due to mergers or acquisitions of publicly held companies that trade on a major exchange are implemented when the transaction occurs, even if both of the companies are not in the same headline index, and regardless of the size of the change. All other changes of 5.00% or more (due to, for example, company stock repurchases, private placements, redemptions, exercise of options, warrants, conversion of preferred stock, notes, debt, equity participation units, at-the-market offerings, or other recapitalizations) are made weekly and are announced on Fridays for implementation after the close of trading on the following Friday. Changes of less than 5.00% are accumulated and made quarterly on the third Friday of March, June, September, and December, and are usually announced two to five days prior. If a change in a company’s shares outstanding of 5.00% or more causes a company’s IWF to change by five percentage points or more, the IWF is updated at the same time as the share change. IWF changes resulting from partial tender offers are considered on a case by case basis.

Historical Performance of the SPX

The following graph sets forth the daily historical performance of the SPX in the period from January 1, 2008 through September 8, 2021. 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 orange line in the graph represents the SPX’s hypothetical Coupon Barrier of 3,160.35 (rounded to two decimal places), which is 70% of the SPX’s hypothetical Initial Value of 4,514.78, which was the SPX’s closing level on September 8, 2021. The horizontal gray line in the graph represents the SPX’s hypothetical Downside Threshold of 2,934.61 (rounded to two decimal places), which is 65% of the SPX’s hypothetical Initial Value.

The NASDAQ-100^® Index

The NDX is intended to measure the performance of the 100 largest domestic and international non-financial securities listed on NASDAQ based on market capitalization. The NDX reflects companies across major industry groups including computer hardware and software, telecommunications, retail/wholesale trade and biotechnology. It does not contain securities of financial companies including investment companies.

The NDX began trading on January 31, 1985 at a base value of 125.00. The NDX is calculated and published by Nasdaq, Inc. In administering the NDX, Nasdaq, Inc. will exercise reasonable discretion as it deems appropriate.

Underlying Stock Eligibility Criteria

NDX eligibility is limited to specific security types only. The security types eligible for the NDX include foreign or domestic common stocks, ordinary shares, ADRs and tracking stocks. Security types not included in the NDX are closed-end funds, convertible debt securities, exchange traded funds, limited liability companies, limited partnership interests, preferred stocks, rights, shares or units of beneficial interest, warrants, units, and other derivative securities. The NDX does not contain securities of investment companies. For purposes of the NDX eligibility criteria, if the security is a depositary receipt representing a security of a non-U.S. issuer, then references to the “issuer” are references to the issuer of the underlying security.

Initial Eligibility Criteria

To be eligible for initial inclusion in the NDX, a security must be listed on NASDAQ and meet the following criteria:

●	the security’s U.S. listing must be exclusively on the Nasdaq Global Select Market or the Nasdaq Global Market (unless the security was dually listed on another U.S. market prior to January 1, 2004 and has continuously maintained such listing);

●	the security must be of a non-financial company;

●	the security may not be issued by an issuer currently in bankruptcy proceedings;

●	the security must have a minimum three-month average daily trading volume of at least 200,000 shares;

●	if the issuer of the security is organized under the laws of a jurisdiction outside the U.S., then such security must have listed options on a recognized options market in the U.S. or be eligible for listed-options trading on a recognized options market in the U.S.;

●	the issuer of the security may not have entered into a definitive agreement or other arrangement which would likely result in the security no longer being eligible for inclusion in the NDX;

●	the issuer of the security may not have annual financial statements with an audit opinion that is currently withdrawn; and

●	the issuer of the security must have “seasoned” on NASDAQ, NYSE or NYSE Amex. Generally, a company is considered to be seasoned if it has been listed on a market for at least three full months (excluding the first month of initial listing).

Continued Eligibility Criteria

In addition, to be eligible for continued inclusion in the NDX, the following criteria apply:

●	the security’s U.S. listing must be exclusively on the Nasdaq Global Select Market or the Nasdaq Global Market;

●	the security must be of a non-financial company;

●	the security may not be issued by an issuer currently in bankruptcy proceedings;

PS-18

●	the security must have a minimum three-month average daily trading volume of at least 200,000 shares;

●

if the issuer of the security is organized under the laws of a jurisdiction outside the U.S., then such security must have listed options on a recognized options market in the U.S. or be eligible for listed-options trading on a recognized options market in the U.S. (measured annually during the ranking review process);

●

the security must have an adjusted market capitalization equal to or exceeding 0.10% of the aggregate adjusted market capitalization of the NDX at each month-end. In the event a company does not meet this criterion for two consecutive month-ends, it will be removed from the NDX effective after the close of trading on the third Friday of the following month; and

●	the issuer of the security may not have annual financial statements with an audit opinion that is currently withdrawn.

Computation of the NDX

The value of the NDX equals the aggregate value of the NDX share weights (the “NDX Shares”) of each of the NDX securities multiplied by each such security’s last sale price (last sale price refers to the last sale price on NASDAQ), and divided by the divisor of the NDX. If trading in an NDX security is halted while the market is open, the last traded price for that security is used for all NDX computations until trading resumes. If trading is halted before the market is open, the previous day’s last sale price is used. The formula for determining the NDX value is as follows:

Aggregated Adjusted Market Value

Divisor

The NDX is ordinarily calculated without regard to cash dividends on NDX securities. The NDX is calculated during the trading day and is disseminated once per second from 09:30:01 to 17:16:00 ET. The closing level of the NDX may change up until 17:15:00 ET due to corrections to the last sale price of the NDX securities. The official closing value of the NDX is ordinarily disseminated at 17:16:00 ET.

NDX Maintenance

Changes to NDX Constituents

Changes to the NDX constituents may be made during the annual ranking review. In addition, if at any time during the year other than the annual review, it is determined that an NDX security issuer no longer meets the criteria for continued inclusion in the NDX, or is otherwise determined to have become ineligible for continued inclusion in the NDX, it is replaced with the largest market capitalization issuer not currently in the NDX that meets the applicable eligibility criteria for initial inclusion in the NDX.

Ordinarily, a security will be removed from the NDX at its last sale price. However, if at the time of its removal the NDX security is halted from trading on its primary listing market and an official closing price cannot readily be determined, the NDX security may, in Nasdaq, Inc.’s discretion, be removed at a price of $0.00000001 (“zero price”). This zero price will be applied to the NDX security after the close of the market but prior to the time the official closing value of the NDX is disseminated.

Divisor Adjustments

The divisor is adjusted to ensure that changes in the NDX constituents either by corporate actions (that adjust either the price or shares of an NDX security) or NDX participation outside of trading hours do not affect the value of the NDX. All divisor changes occur after the close of the applicable index security markets.

Quarterly NDX Rebalancing

The NDX will be rebalanced on a quarterly basis if it is determined that (1) the current weight of the single NDX security with the largest market capitalization is greater than 24.0% of the NDX or (2) the collective weight of those securities whose individual current weights are in excess of 4.5% exceeds 48.0% of the NDX. In addition, a “special rebalancing” of the NDX may be conducted at any time if Nasdaq, Inc. determines it necessary to maintain the integrity and continuity of the NDX. If either one or both of the above weight distribution conditions are met upon quarterly review, or Nasdaq, Inc. determines that a special rebalancing is necessary, a weight rebalancing will be performed.

If the first weight distribution condition is met and the current weight of the single NDX security with the largest market capitalization is greater than 24.0%, then the weights of all securities with current weights greater than 1.0% (“large securities”) will be scaled down proportionately toward 1.0% until the adjusted weight of the single largest NDX security reaches 20.0%.

If the second weight distribution condition is met and the collective weight of those securities whose individual current weights are in excess of 4.5% (or adjusted weights in accordance with the previous step, if applicable) exceeds 48.0% of the NDX, then the weights of all such large securities in that group will be scaled down proportionately toward 1.0% until their collective weight, so adjusted, is equal to 40.0%.

The aggregate weight reduction among the large securities resulting from either or both of the rebalancing steps above will then be redistributed to those securities with weightings of less than 1.0% (“small securities”) in the following manner. In the first iteration, the weight of the largest small security will be scaled upwards by a factor which sets it equal to the average NDX weight of 1.0%. The weights of each of the smaller remaining small securities will be scaled up by the same factor reduced in relation to each security’s relative ranking among the small securities such that the smaller the NDX security in the ranking, the less its weight will be scaled upward. This is intended to reduce the market impact of the weight rebalancing on the smallest component securities in the NDX.

PS-19

In the second iteration of the small security rebalancing, the weight of the second largest small security, already adjusted in the first iteration, will be scaled upwards by a factor which sets it equal to the average NDX weight of 1.0%. The weights of each of the smaller remaining small securities will be scaled up by this same factor reduced in relation to each security’s relative ranking among the small securities such that, once again, the smaller the security in the ranking, the less its weight will be scaled upward. Additional iterations will be performed until the accumulated increase in weight among the small securities equals the aggregate weight reduction among the large securities that resulted from the rebalancing in accordance with the two weight distribution conditions discussed above.

Finally, to complete the rebalancing process, once the final weighting percentages for each NDX security have been set, the NDX Shares will be determined anew based upon the last sale prices and aggregate capitalization of the NDX at the close of trading on the last calendar day in February, May, August and November. Changes to the NDX Shares will be made effective after the close of trading on the third Friday in March, June, September and December, and an adjustment to the divisor is made to ensure continuity of the NDX. Ordinarily, new rebalanced NDX Shares will be determined by applying the above procedures to the current NDX Shares. However, Nasdaq, Inc. may, from time to time, determine rebalanced weights, if necessary, by applying the above procedure to the actual current market capitalization of the NDX components. In such instances, Nasdaq, Inc. would announce the different basis for rebalancing prior to its implementation.

During the quarterly rebalancing, data is cutoff as of the previous month end and no changes are made to the NDX from that cutoff until the quarterly index share change effective date, except in the case of changes due to corporate actions with an ex-date.

Adjustments for Corporate Actions

Changes in the price and/or NDX Shares driven by corporate events such as stock dividends, splits, and certain spin-offs and rights issuances will be adjusted on the ex-date. If the change in total shares outstanding arising from other corporate actions is greater than or equal to 10.0%, the change will be made as soon as practicable. Otherwise, if the change in total shares outstanding is less than 10.0%, then all such changes are accumulated and made effective at one time on a quarterly basis after the close of trading on the third Friday in each of March, June, September, and December. The NDX Shares are derived from the security’s total shares outstanding. The NDX Shares are adjusted by the same percentage amount by which the total shares outstanding have changed.

Historical Performance of the NDX

The following graph sets forth the daily historical performance of the NDX in the period from January 1, 2008 through September 8, 2021. 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 orange line in the graph represents the NDX’s hypothetical Coupon Barrier of 10,934.60 (rounded to two decimal places), which is 70% of the NDX’s hypothetical Initial Value of 15,620.85, which was the NDX’s closing level on September 8, 2021. The horizontal gray line in the graph represents the NDX’s hypothetical Downside Threshold of 10,153.55 (rounded to two decimal places), which is 65% of the NDX’s hypothetical Initial Value. The actual Initial Value, Coupon Barrier and Downside Threshold will be determined on the Trade Date.

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

Before investing in the Notes, you should consult publicly available sources for the levels of the NDX.

Correlation of the Underlyings

The graph below illustrates the daily performance of the RTY, the SPX and the NDX from January 1, 2008 through September 8, 2021. For comparison purposes, each Underlying has been “normalized” to have a closing level of 100 on January 1, 2008 by dividing the closing level of that Underlying on each trading day by the closing level of that Underlying on January 1, 2008 and multiplying by 100. We obtained the closing levels used to determine the normalized closing levels set forth below from Bloomberg L.P., without independent verification.

The correlation of a group of Underlyings represents a statistical measurement of the degree to which the returns of those Underlyings were similar to each other over a given period in terms of timing and direction. The correlation between a group of Underlyings is scaled from 1.0 to -1.0, with 1.0 indicating perfect positive correlation (i.e., the value of all Underlyings are increasing together or decreasing together and the ratio of their returns has been constant), 0 indicating no correlation (i.e., there is no statistical relationship between the returns of that group of Underlyings) and -1.0 indicating perfect negative correlation (i.e., as the value of one Underlying increases, the value of the other Underlyings decrease and the ratio of their returns has been constant).

The graph below illustrates the historical performance of each Underlying relative to each other over the time period shown and provides an indication of how close the relative performance of each Underlying has historically been to the other Underlyings. A closer relationship between the daily returns of two or more underlying assets over a given period indicates that such underlying assets have been more positively correlated. Lower (or more-negative) correlation among two or more underlying assets over a given period may indicate that it is less likely that those underlying assets will subsequently move in the same direction. Therefore, lower correlation among the Underlyings may indicate a greater potential for one of the Underlyings to close below its respective Coupon Barrier on any trading day during an Observation Period or below its respective Downside Threshold on the Final Observation Date, as applicable, because there may be a greater likelihood that at least one of the Underlyings will decrease in value significantly. However, even if the Underlyings have a higher positive correlation, one or all of the Underlyings may close below the respective Coupon Barrier(s) on any trading day during an Observation Period or below the respective Downside Threshold(s) on the Final Observation Date, as applicable, as the Underlyings may each decrease in value. Moreover, the actual correlation among the Underlyings may differ, perhaps significantly, from their historical correlation. Although the correlation of the Underlyings’ performance may change over the term of the Notes, the economic terms of the Notes, including the Contingent Coupon Rate, Downside Threshold and Coupon Barrier are determined, in part, based on the correlation of the Underlyings’ performance calculated using our and our affiliates' pricing models at the time when the terms of the Notes are finalized. All other things being equal, a higher Contingent Coupon Rate and lower Downside Threshold and Coupon Barrier is generally associated with lower correlation among the Underlyings, which may indicate a greater potential for missed Contingent Coupon Payments and/or a significant loss on your investment at maturity. See “Risk Factors — You are exposed to the market risk of each Underlying”and “—Because the Notes are linked to the performance of the least performing among the RTY, the SPX and the NDX, you are exposed to greater risk of receiving no Contingent Coupon Payments or sustaining a significant loss on your investment than if the Notes were linked to just the RTY, just the SPX or just the NDX” herein.

Past performance and correlation of the Underlyings are not indicative of the future performance or correlation of the Underlyings.

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

BofAS, an affiliate of BofA Finance and the lead selling agent for the sale of the Notes, will receive an underwriting discount of $0.10 for any Note sold in this offering. UBS, as selling agent for sales of the Notes, expects to purchase from BofAS, and BofAS expects to sell to UBS, all of the Notes sold in this offering for $9.90 per Note. UBS proposes to offer the Notes to the public at a price of $10.00 per Note. UBS will receive an underwriting discount of $0.10 for each Note it sells to the public. The underwriting discount will be received by UBS and its financial advisors collectively. If all of the Notes are not sold at the initial offering price, BofAS may change the public offering price and other selling terms.

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

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

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

As agreed by BofAS and UBS, for approximately a four-month period after the Trade Date, to the extent BofAS offers to buy the Notes in the secondary market, it will do so at a price that will exceed the estimated value of the Notes at that time. The amount of this excess will decline on a straight line basis over that period. Thereafter, if BofAS buys or sells your Notes, it will do so at prices that reflect the estimated value determined by reference to its pricing models at that time. Any price at any time after the Trade Date will be based on then-prevailing market conditions and other considerations, including the performance of the Underlyings and the remaining term of the Notes. However, none of us, the Guarantor, BofAS, UBS or any other party 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.

Sales Outside of the United States

The Notes have not been approved for public sale in any jurisdiction outside of the United States. There has been no registration or filing as to the Notes with any regulatory, securities, banking, or local authority outside of the United States and no action has been taken by BofA Finance, BAC, BofAS or any other affiliate of BAC, or by UBS or any of its affiliates, to offer the Notes in any jurisdiction other than the United States. As such, these Notes are made available to investors outside of the United States only in jurisdictions where it is lawful to make such offer or sale and only under circumstances that will result in compliance with applicable laws and regulations, including private placement requirements.

Further, no offer or sale of the Notes is being made to residents of:

●

Belize

●

Aruba

●

Botswana

You are urged to carefully review the selling restrictions that may be applicable to your jurisdiction beginning on page S-68 of the accompanying prospectus supplement.

European Economic Area and United Kingdom

None of this pricing supplement, the accompanying product supplement, the accompanying prospectus or the accompanying prospectus supplement is a prospectus for the purposes of the Prospectus Regulation (as defined below). This pricing supplement, the accompanying product supplement, the accompanying prospectus and the accompanying prospectus supplement have been prepared on the basis that any offer of Notes in any Member State of the European Economic Area (the “EEA”) or in the United Kingdom (each, a “Relevant State”) will only be made to a legal entity which is a qualified investor under the Prospectus Regulation (“Qualified Investors”). Accordingly any person making or intending to make an offer in that Relevant State of Notes which are the subject of the offering contemplated in this pricing supplement, the accompanying product

PS-23

supplement, the accompanying prospectus and the accompanying prospectus supplement may only do so with respect to Qualified Investors. Neither BofA Finance nor BAC has authorized, nor does it authorize, the making of any offer of Notes other than to Qualified Investors. The expression “Prospectus Regulation” means Regulation (EU) 2017/1129.

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

United Kingdom

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

Any invitation or inducement to engage in investment activity (within the meaning of Section 21 of the FSMA) in connection with the issue or sale of the Notes may only be communicated or caused to be communicated in circumstances in which Section 21(1) of the FSMA does not apply to the Issuer or the 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 Underlyings. The related guarantees are BAC’s obligations. Any payments on the Notes, including any Contingent Coupon Payments, depend on the credit risk of BofA Finance and BAC and on the performance of each of the Underlyings. The economic terms of the Notes reflect our and BAC’s actual or perceived creditworthiness at the time of pricing and are based on BAC’s internal funding rate, which is the rate it would pay to borrow funds through the issuance of market-linked Notes, and the economic terms of certain related hedging arrangements it enters into. BAC’s internal funding rate is typically lower than the rate it would pay when it issues conventional fixed or floating rate debt securities. This difference in funding rate, as well as the underwriting discount and the hedging related charges described elsewhere in this pricing supplement, will reduce the economic terms of the Notes to you and the initial estimated value of the Notes. Due to these factors, the public offering price you pay to purchase the Notes will be greater than the initial estimated value of the Notes as of the Trade Date. On the cover page of this preliminary pricing supplement, we have provided the initial estimated value range for the Notes. The final pricing supplement will set forth the initial estimated value of the Notes as of the Trade Date.

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

U.S. Federal Income Tax Summary

The following summary of the material U.S. federal income and estate 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 IRS, and judicial decisions, all as currently in effect and all of which are subject to differing interpretations or to change, possibly with retroactive effect. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax consequences described below. This summary does not include any description of the tax laws of any state or local governments, or of any foreign government, that may be applicable to a particular holder.

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

This summary is directed solely to U.S. Holders and Non-U.S. Holders that, except as otherwise specifically noted, will purchase the Notes upon original issuance and will hold the Notes as capital assets within the meaning of Section 1221 of the Code, which generally means property held for investment, and that are not excluded from the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus.

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

General

Although there is no statutory, judicial, or administrative authority directly addressing the characterization of the Notes, we intend to treat the Notes for all tax purposes as contingent income-bearing single financial contracts with respect to the Underlyings and under the terms of the Notes, we and every investor in the Notes agree, in the absence of an administrative determination or judicial ruling to the contrary, to treat the Notes in accordance with such characterization. In the opinion of our counsel, Sidley Austin LLP, it is reasonable to treat the Notes as contingent income-bearing single financial contracts with respect to the Underlyings. However, Sidley Austin LLP has advised us that it is unable to conclude that it is more likely than not that this treatment will be upheld. This discussion assumes that the Notes constitute contingent income-bearing single financial contracts with respect to the Underlyings for U.S. federal income tax purposes. If the Notes did not constitute contingent income-bearing single financial contracts, the tax consequences described below would be materially different.

This characterization of the Notes is not binding on the IRS or the courts. No statutory, judicial, or administrative authority directly addresses the characterization of the Notes or any similar instruments for U.S. federal income tax purposes, and no ruling is being requested from the IRS with respect to their proper characterization and treatment. Due to the absence of authorities on point, significant aspects of the U.S. federal income tax consequences of an investment in the Notes are not certain, and no assurance can be given that the IRS or any court will agree with the characterization and tax treatment described in this pricing supplement. Accordingly, you are urged to consult your tax advisor regarding all aspects of the U.S. federal income tax consequences of an investment in the Notes, including possible alternative characterizations.

Unless otherwise stated, the following discussion is based on the characterization described above. The discussion in this section assumes that there is a significant possibility of a significant loss of principal on an investment in the Notes.

We will not attempt to ascertain whether the issuer of any component stocks included in the Underlyings would be treated as a “passive foreign investment company” (“PFIC”), within the meaning of Section 1297 of the Code, or a United States real property holding corporation, within the meaning of Section 897(c) of the Code. If the issuer of one or more stocks included in the Underlyings were so treated, certain adverse U.S. federal income tax consequences could possibly apply to a holder of the Notes. You should refer to information filed with the SEC by the issuers of the component stocks included in each Underlying and consult your tax advisor regarding the possible consequences to you, if any, if any issuer of a component stock included in the Underlyings is or becomes a PFIC or is or becomes a United States real property holding corporation.

U.S. Holders

Although the U.S. federal income tax treatment of any Contingent Coupon Payment on the Notes is uncertain, we intend to take the position, and the following discussion assumes, that any Contingent Coupon Payment constitutes taxable ordinary income to a U.S. Holder at the time received or accrued in accordance with the U.S. Holder’s regular method of accounting. By purchasing the Notes you agree, in the absence of an administrative determination or judicial ruling to the contrary, to treat any Contingent Coupon Payment as described in the preceding sentence.

Upon receipt of a cash payment at maturity or upon a sale, exchange, or redemption of the Notes prior to maturity, a U.S. Holder generally will recognize capital gain or loss equal to the difference between the amount realized (other than amounts representing any Contingent Coupon Payment, which would be taxed as described above) and the U.S. Holder’s tax basis in the Notes. A U.S. Holder’s tax basis in the Notes will equal

PS-26

the amount paid by that holder to acquire them. This capital gain or loss generally will be long-term capital gain or loss if the U.S. Holder held the Notes for more than one year. The deductibility of capital losses is subject to limitations.

Alternative Tax Treatments. Due to the absence of authorities that directly address the proper tax treatment of the Notes, prospective investors are urged to consult their tax advisors regarding all possible alternative tax treatments of an investment in the Notes. In particular, the IRS could seek to subject the Notes to the Treasury regulations governing contingent payment debt instruments. If the IRS were successful in that regard, the timing and character of income on the Notes would be affected significantly. Among other things, a U.S. Holder would be required to accrue original issue discount every year at a “comparable yield” determined at the time of issuance. In addition, any gain realized by a U.S. Holder at maturity or upon a sale, exchange, or redemption of the Notes generally would be treated as ordinary income, and any loss realized at maturity or upon a sale, exchange, or redemption of the Notes generally would be treated as ordinary loss to the extent of the U.S. Holder’s prior accruals of original issue discount, and as capital loss thereafter.

In addition, it is possible that the Notes could be treated as a unit consisting of a deposit and a put option written by the Note holder, in which case the timing and character of income on the Notes would be affected significantly.

The IRS released Notice 2008-2 (the “Notice”), which sought comments from the public on the taxation of financial instruments currently taxed as “prepaid forward contracts.” This Notice addresses instruments such as the Notes. According to the Notice, the IRS and Treasury are considering whether a holder of an instrument such as the Notes should be required to accrue ordinary income on a current basis, regardless of whether any payments are made prior to maturity. It is not possible to determine what guidance the IRS and Treasury will ultimately issue, if any. Any such future guidance may affect the amount, timing and character of income, gain, or loss in respect of the Notes, possibly with retroactive effect.

The IRS and Treasury are also considering additional issues, including whether additional gain or loss from such instruments should be treated as ordinary or capital, whether foreign holders of such instruments should be subject to withholding tax on any deemed income accruals, whether Section 1260 of the Code, concerning certain “constructive ownership transactions,” generally applies or should generally apply to such instruments, and whether any of these determinations depend on the nature of the underlying asset.

In addition, proposed Treasury regulations require the accrual of income on a current basis for contingent payments made under certain notional principal contracts. The preamble to the regulations states that the “wait and see” method of accounting does not properly reflect the economic accrual of income on those contracts, and requires current accrual of income for some contracts already in existence. While the proposed regulations do not apply to prepaid forward contracts, the preamble to the proposed regulations expresses the view that similar timing issues exist in the case of prepaid forward contracts. If the IRS or Treasury publishes future guidance requiring current economic accrual for contingent payments on prepaid forward contracts, it is possible that you could be required to accrue income over the term of the Notes.

Because of the absence of authority regarding the appropriate tax characterization of the Notes, it is also possible that the IRS could seek to characterize the Notes in a manner that results in tax consequences that are different from those described above. For example, the IRS could possibly assert that any gain or loss that a holder may recognize at maturity or upon the sale, exchange, or redemption of the Notes should be treated as ordinary gain or loss.

Because each Underlying is an index that periodically rebalances, it is possible that the Notes could be treated as a series of contingent income-bearing single financial contracts, each of which matures on the next rebalancing date. If the Notes were properly characterized in such a manner, a U.S. Holder would be treated as disposing of the Notes on each rebalancing date in return for new Notes that mature on the next rebalancing date, and a U.S. Holder would accordingly likely recognize capital gain or loss on each rebalancing date equal to the difference between the holder’s tax basis in the Notes (which would be adjusted to take into account any prior recognition of gain or loss) and the fair market value of the Notes on such date.

Non-U.S. Holders

Because the U.S. federal income tax treatment of the Notes (including any Contingent Coupon Payment) is uncertain, we (or the applicable paying agent) will withhold U.S. federal income tax at a 30% rate (or at a lower rate under an applicable income tax treaty) on the entire amount of any Contingent Coupon Payment made unless such payments are effectively connected with the conduct by the Non-U.S. Holder of a trade or business in the U.S. (in which case, to avoid withholding, the Non-U.S. Holder will be required to provide a Form W-8ECI). We (or the applicable paying agent) will not pay any additional amounts in respect of such withholding. To claim benefits under an income tax treaty, a Non-U.S. Holder must obtain a taxpayer identification number and certify as to its eligibility under the appropriate treaty’s limitations on benefits article, if applicable. In addition, special rules may apply to claims for treaty benefits made by Non-U.S. Holders that are entities rather than individuals. The availability of a lower rate of withholding under an applicable income tax treaty will depend on whether such rate applies to the characterization of the payments under U.S. federal income tax laws. A Non-U.S. Holder that is eligible for a reduced rate of U.S. federal withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS.

Except as discussed below, a Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax for amounts paid in respect of the Notes (not including, for the avoidance of doubt, amounts representing any Contingent Coupon Payment which would be subject to the rules discussed in the previous paragraph) upon the sale, exchange, or redemption of the Notes or their settlement at maturity, provided that the Non-U.S. Holder complies with applicable certification requirements and that the payment is not effectively connected with the conduct by the Non-U.S. Holder of a U.S. trade or business. Notwithstanding the foregoing, gain from the sale, exchange, or redemption of the Notes or their settlement at

PS-27

maturity may be subject to U.S. federal income tax if that Non-U.S. Holder is a non-resident alien individual and is present in the U.S. for 183 days or more during the taxable year of the sale, exchange, redemption, or settlement and certain other conditions are satisfied.

If a Non-U.S. Holder of the Notes is engaged in the conduct of a trade or business within the U.S. and if any Contingent Coupon Payment and gain realized on the settlement at maturity, or upon sale, exchange or redemption of the Notes, is effectively connected with the conduct of such trade or business (and, if certain tax treaties apply, is attributable to a permanent establishment maintained by the Non-U.S. Holder in the U.S.), the Non-U.S. Holder, although exempt from U.S. federal withholding tax, generally will be subject to U.S. federal income tax on such Contingent Coupon Payment and gain on a net income basis in the same manner as if it were a U.S. Holder. Such Non-U.S. Holders should read the material under the heading “—U.S. Holders,” for a description of the U.S. federal income tax consequences of acquiring, owning, and disposing of the Notes. In addition, if such Non-U.S. Holder is a foreign corporation, it may also be subject to a branch profits tax equal to 30% (or such lower rate provided by any applicable tax treaty) of a portion of its earnings and profits for the taxable year that are effectively connected with its conduct of a trade or business in the U.S., subject to certain adjustments.

A “dividend equivalent” payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a Non-U.S. Holder. Under Treasury regulations, payments (including deemed payments) with respect to equity-linked instruments (“ELIs”) that are “specified ELIs” may be treated as dividend equivalents if such specified ELIs reference an interest in an “underlying security,” which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, IRS guidance provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2023. Based on our determination that the Notes are not delta-one instruments, Non-U.S. Holders should not be subject to withholding on dividend equivalent payments, if any, under the Notes. However, it is possible that the Notes could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Underlyings or the Notes, and following such occurrence the Notes could be treated as subject to withholding on dividend equivalent payments. Non-U.S. Holders that enter, or have entered, into other transactions in respect of the Underlyings or the Notes should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the Notes and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.

As discussed above, alternative characterizations of the Notes for U.S. federal income tax purposes are possible. Should an alternative characterization, by reason of change or clarification of the law, by regulation or otherwise, cause payments as to the Notes to become subject to withholding tax in addition to the withholding tax described above, tax will be withheld at the applicable statutory rate. Prospective Non-U.S. Holders should consult their own tax advisors regarding the tax consequences of such alternative characterizations.

U.S. Federal Estate Tax. Under current law, while the matter is not entirely clear, individual Non-U.S. Holders, and entities whose property is potentially includible in those individuals’ gross estates for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty benefit, a Note is likely to be treated as U.S. situs property, subject to U.S. federal estate tax. These individuals and entities should consult their own tax advisors regarding the U.S. federal estate tax consequences of investing in a Note.

Features	Key Dates¹
❑ Contingent Coupon Payment — We will pay you a Contingent Coupon Payment on each quarterly Coupon Payment Date if, and only if, the closing level of each Underlying on each trading day during the applicable quarterly Observation Period is greater than or equal to its Coupon Barrier. Otherwise, no Contingent Coupon Payment will be paid for that quarter. ❑ Issuer Callable — Beginning in December 2021, on any Coupon Payment Date prior to the Maturity Date, the issuer may, in its sole discretion, call the Notes in whole, but not in part, and pay you the Stated Principal Amount plus any Contingent Coupon Payment otherwise due on such Coupon Payment Date. If the Notes are not called, investors may have full downside market exposure to the Least Performing Underlying at maturity. ❑ Downside Exposure with Contingent Repayment of Principal at Maturity — If the Notes are not called prior to maturity and the Final Value of the Least Performing Underlying on the Final Observation Date is greater than or equal to its Downside Threshold, you will receive the Stated Principal Amount at maturity (plus any final Contingent Coupon Payment otherwise due on the Maturity Date). However, if the Final Value of the Least Performing Underlying on the Final Observation Date is less than its Downside Threshold, you will receive less than the Stated Principal Amount of your Notes at maturity, resulting in a loss that is proportionate to the decline in the closing level of the Least Performing Underlying from the Trade Date to the Final Observation Date, up to a 100% loss of your investment. Any payment on the Notes is subject to the creditworthiness of BofA Finance and the Guarantor.

If the Notes are called, no further payments will be made on the Notes.
Observation Period	Each Observation Period will consist of each trading day from, but excluding, an Observation Period End Date to, and including, the following Observation Period End Date, excluding any date or dates that the calculation agent determines is not a trading day with respect to any Underlying; provided that the first Observation Period will consist of each trading day from, but excluding, the Trade Date to, and including, the first Observation Period End Date.

Coupon Payment Dates¹	See “Observation Period End Dates and Coupon Payment Dates” on page PS-6.
Contingent Coupon Payment/Contingent Coupon Rate	If the closing level of each Underlying on each trading day during the applicable Observation Period is greater than or equal to its Coupon Barrier, we will make a Contingent Coupon Payment with respect to that Observation Period on the related Coupon Payment Date. However, if the closing level of any Underlying on any trading day during the applicable Observation Period is below its Coupon Barrier, no Contingent Coupon Payment will accrue or be payable on the related Coupon Payment Date. Each Contingent Coupon Payment will be in the amount of between [$0.21625 to $0.22125] for each $10.00 Stated Principal Amount (based on the per

	annum Contingent Coupon Rate of between [8.65% to 8.85%]) and will be payable, if applicable, on the related Coupon Payment Date. The actual Contingent Coupon Payment and Contingent Coupon Rate will be determined on the Trade Date. Contingent Coupon Payments on the Notes are not guaranteed. We will not pay you the Contingent Coupon Payment for any Observation Period in which the closing level of any Underlying on any trading day during the Observation Period is less than its Coupon Barrier, even if the closing level of each Underlying is above its Coupon Barrier on every other trading day during the Observation Period.
Payment At Maturity (per $10.00 Stated Principal Amount)	If the Notes are not called prior to maturity and the Final Value of the Least Performing Underlying on the Final Observation Date is greater than or equal to its Downside Threshold, on the Maturity Date we will pay you the Stated Principal Amount plus any Contingent Coupon Payment otherwise due on the Maturity Date. If the Notes are not called prior to maturity and the Final Value of the Least Performing Underlying on the Final Observation Date is less than its Downside Threshold, we will pay you a cash payment on the Maturity Date that is less than your Stated Principal Amount and may be zero, resulting in a loss that is proportionate to the negative Underlying Return of the Least Performing Underlying, equal to: $10.00 × (1 + Underlying Return of the Least Performing Underlying) *Accordingly, you may lose all or* *a substantial portion of your Stated Principal Amount at maturity, depending on how significantly the* Least Performing Underlying declines, even if the Final Value of each other Underlying is above its Downside Threshold**.

Investment Description
The Trigger Callable Contingent Yield Notes (with daily coupon observation) linked to the least performing of the Russell 2000^® Index, the S&P 500^® Index and the NASDAQ-100^® Index (each, an “Underlying”) due September 12, 2024 (the “Notes”) are senior unsecured obligations issued by BofA Finance LLC (“BofA Finance” or the “issuer”), a direct, wholly-owned subsidiary of Bank of America Corporation (“BAC” or the “Guarantor”), which are fully and unconditionally guaranteed by the Guarantor. The Notes will pay a Contingent Coupon Payment on each quarterly Coupon Payment Date if, and only if, the closing level of each Underlying on each trading day during the applicable quarterly Observation Period is greater than or equal to its Coupon Barrier. If the closing level of any Underlying on any trading day during an Observation Period is less than its Coupon Barrier, no Contingent Coupon Payment will accrue or be paid on the related Coupon Payment Date. Beginning in December 2021, on any Coupon Payment Date prior to the Maturity Date, the issuer may, in its sole discretion, call the Notes in whole, but not in part, and pay you the Stated Principal Amount plus any Contingent Coupon Payment otherwise due on such Coupon Payment Date, and no further amounts will be owed to you. If the Notes have not previously been called, at maturity, the amount you receive will depend on the Final Value of the Least Performing Underlying on the Final Observation Date. If the Final Value of the Least Performing Underlying on the Final Observation Date is greater than or equal to its Downside Threshold, you will receive the Stated Principal Amount at maturity (plus any final Contingent Coupon Payment otherwise due on the Maturity Date). However, if the Notes have not been called prior to maturity and the Final Value of the Least Performing Underlying on the Final Observation Date is less than its Downside Threshold, you will receive less than the Stated Principal Amount at maturity, resulting in a loss that is proportionate to the decline in the closing level of the Least Performing Underlying from the Trade Date to the Final Observation Date, up to a 100% loss of your investment. The “Least Performing Underlying” is the Underlying with the lowest Underlying Return from the Trade Date to the Final Observation Date. Investing in the Notes involves significant risks. You may lose a substantial portion or all of your initial investment. You will be exposed to the market risk of each Underlying on each trading day during the Observation Periods and on the Final Observation Date. Any decline in the level of one Underlying may negatively affect your return and will not be offset or mitigated by a lesser decline or any potential increase in the level of any other Underlying. You will therefore be adversely affected if any Underlying performs poorly, regardless of the performance of the other Underlyings. You will not receive dividends or other distributions paid on any stocks included in the Underlyings or participate in any appreciation of any Underlying. The contingent repayment of the Stated Principal Amount applies only if you hold the Notes to maturity or earlier call by the issuer. Any payment on the Notes, including any repayment of the Stated Principal Amount, is subject to the creditworthiness of BofA Finance and the Guarantor and is not, either directly or indirectly, an obligation of any third party.
