	Market Linked Securities— Auto-Callable with Leveraged Upside Participation and Contingent Downside Principal at Risk Securities Linked to the Lowest Performing of the S&P 500^® Index, the Dow Jones Industrial Average^® and the Common Stock of Microsoft Corporation due October 27, 2028
■ Linked to Lowest Performing of the S&P 500^® Index, the Dow Jones Industrial Average^® and the Common Stock of Microsoft Corporation(each referred to as an “Underlying”) ■ Unlike ordinary debt securities, the Securities do not pay interest or repay a fixed amount of principal at maturity and are subject to potential automatic call upon the terms described below. Whether the Securities are automatically called for a fixed call premium or, if not automatically called, the Maturity Payment Amount, will depend, in each case, on the performance of the Lowest Performing Underlying on the Call Date or the Final Calculation Day, as applicable. The Lowest Performing Underlying on the Call Date or the Final Calculation Day is the Underlying that has the lowest closing value on the Call Date or the Final Calculation Day, as applicable, as a percentage of its Starting Value ■ Automatic Call. If the closing value of the Lowest Performing Underlying on the Call Date is greater than or equal to its Starting Value, the Securities will be automatically called for the principal amount plus a Call Premium of at least 22.00% of the principal amount (to be determined on the Pricing Date) ■ Maturity Payment Amount. If the Securities are not automatically called, you will receive a Maturity Payment Amount that may be greater than, equal to or less than the principal amount of the Securities, depending on the performance of the Lowest Performing Underlying from its Starting Value to its Ending Value. The Maturity Payment Amount will reflect the following terms: ■ If the value of the Lowest Performing Underlying increases, you will receive the principal amount plus a positive return equal to the Upside Participation Rate of 150% of the percentage increase in the value of the Lowest Performing Underlying from its Starting Value ■ If the value of the Lowest Performing Underlying decreases but the decrease is not more than 25%, you will receive the principal amount ■ If the value of the Lowest Performing Underlying decreases by more than 25%, you will have full downside exposure to the decrease in the value of the Lowest Performing Underlying from its Starting Value, and you will lose more than 25%, and possibly all, of the principal amount of your Securities ■ Investors may lose a significant portion, or all, of the principal amount ■ Your return on the Securities will depend solely on the performance of the Underlying that is the Lowest Performing Underlying on the Call Date or the Final Calculation Day, as applicable. You will not benefit in any way from the performance of the better performing Underlyings. Therefore, you will be adversely affected if any Underlying performs poorly, even if the other Underlyings perform favorably ■ If the Securities are automatically called, the positive return on the Securities will be limited to the Call Premium, even if the closing value of the Lowest Performing Underlying on the Call Date significantly exceeds its Starting Value. If the Securities are automatically called, you will not have the opportunity to participate in any appreciation of any Underlying at the Upside Participation Rate ■ All payments on the Securities are subject to the credit risk of BofA Finance LLC (“BofA Finance”), as issuer of the Securities, and Bank of America Corporation (“BAC” or the “Guarantor”), as guarantor of the Securities ■ No periodic interest payments or dividends ■ Securities will not be listed on any securities exchange

The initial estimated value of the Securities as of the Pricing Date is expected to be between $904.25 and $964.25 per Security, which is less than the public offering price listed below. The actual value of your Securities at any time will reflect many factors and cannot be predicted with accuracy. See “Selected Risk Considerations” beginning on page PS-10 of this pricing supplement and “Structuring the Securities” on page PS-26 of this pricing supplement for additional information.
The Securities have complex features and investing in the Securities involves risks not associated with an investment in conventional debt securities.

Market Disruption Events and Postponement Provisions:		The Call Date and the Final Calculation Day are each subject to postponement due to non-trading days and the occurrence of a market disruption event. In addition, each of the Call Settlement Date and the Maturity Date will be postponed if the Call Date or Final Calculation Day, as applicable, is postponed and will be adjusted for non-business days. For more information regarding adjustments to the Call Date, the Final Calculation Day, the Call Settlement Date and the Maturity Date, see “General Terms of the Securities—Consequences of a Market Disruption Event; Postponement of a Calculation Day—Securities Linked to a Single Market Measure” and “—Payment Dates” in the accompanying product supplement. For purposes of the accompanying product supplement, the Call Date and the Final Calculation Day are each a “calculation day” and the Call Settlement Date and the Maturity Date are each a “payment date.” In addition, for information regarding the circumstances that may result in a market disruption event, see “General Terms of the Securities—Certain Terms for Securities Linked to an Index—Market Disruption Events” and “—Certain Terms for Securities Linked to an Underlying Stock—Market Disruption Events” in the accompanying product supplement.
Calculation Agent:		BofA Securities, Inc. (“BofAS”), an affiliate of BofA Finance.
Selling Agents:		BofAS and Wells Fargo Securities, LLC (“WFS”). Under our distribution agreement with BofAS, BofAS will purchase the Securities from us as principal at the public offering price indicated on the cover of this pricing supplement, less the indicated underwriting discount. BofAS will sell the Securities to WFS at the public offering price of the Securities less a concession of up to $25.75 per Security. WFS may provide dealers, which may include Wells Fargo Advisors (“WFA”) (the trade name of the retail brokerage business of WFS’s affiliates, Wells Fargo Clearing Services, LLC and Wells Fargo Advisors Financial Network, LLC), with a selling concession of up to $20.00 per Security. In addition to the concession allowed to WFA, WFS may pay up to $0.75 per Security to WFA as a distribution expense fee for each Security sold by WFA. In addition, in respect of certain Securities sold in this offering, BofAS or its affiliates may pay a fee of up to $3.00 per Security to selected securities dealers in consideration for marketing and other services in connection with the distribution of the Securities to other securities dealers. WFS has advised us that if it, WFA or any of their affiliates makes a secondary market in the Securities at any time up to the Issue Date or during the three-month period following the Issue Date, the secondary market price offered by it, WFA or any of their affiliates will be increased by an amount reflecting a portion of the costs associated with selling, structuring and hedging the Securities that are included in the public offering price of the Securities. Because this portion of the costs is not fully deducted upon issuance, WFS has advised us that any secondary market price it, WFA or any of their affiliates offers during this period will be higher than it otherwise would be outside of this period, as any secondary market price offered outside of this period will reflect the full deduction of the costs as described above. WFS has advised us that the amount of this increase in the secondary market price will decline steadily to zero over this three-month period. If you hold the Securities through an account at WFS, WFA or any of their affiliates, WFS has advised us that it expects that this increase will also be reflected in the value indicated for the Securities on your brokerage account statement. If you hold your Securities through an account at a broker-dealer other than WFS, WFA or any of their affiliates, the value of the Securities on your brokerage account statement may be different than if you held your Securities at WFS, WFA or any of their affiliates.

Investor Considerations

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

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

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

■ are willing to accept the risk that, if the Securities are not automatically called and the Ending Value of the Lowest Performing Underlying on the Final Calculation Day is less than its Threshold Value, they will be fully exposed to the decrease in the value of the Lowest Performing Underlying and will lose more than 25%, and possibly all, of the principal amount per Security at maturity;

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

■ understand that the return on the Securities will depend solely on the performance of the Underlying that is the Lowest Performing Underlying on the Call Date or the Final Calculation Day, as applicable, and that they will not benefit in any way from the performance of the better performing Underlyings;

■ understand that the Securities are riskier than alternative investments linked to only one of the Underlyings or linked to a basket composed of each Underlying;

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

■ are willing to forgo interest payments on the Securities and dividends on the Underlying Stock or the securities included in the Indices; and

■ are willing to hold the Securities until maturity.

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

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

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

■ seek a security with a fixed term;

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

■ are unwilling to accept the risk that the closing value of the Lowest Performing Underlying may decrease by more 25% from its Starting Value to its Ending Value;

■ are unwilling to purchase securities with an estimated value as of the Pricing Date that is lower than the public offering price and that may be as low as the lower estimated value set forth on the cover page;

■ seek current income;

■ are unwilling to accept the risk of exposure to the Underlyings;

■ seek exposure to a basket composed of each Underlying or a similar investment in which the overall return is based on a blend of the performances of the Underlyings, rather than solely on the Lowest Performing Underlying;

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

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

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

The considerations identified above are not exhaustive. Whether or not the Securities are an appropriate investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the appropriateness of an investment in the Securities in light of your particular circumstances. You should also review carefully “Selected Risk Considerations” herein and “Risk Factors” in each of the accompanying product supplement, prospectus supplement and prospectus for risks related to an investment in the Securities. For more information about the Underlyings, please see the sections titled “The S&P 500^® Index”, “The Dow Jones Industrial Average^®” and “The Common Stock of Microsoft Corporation” below.

Determining Timing and Amount of Payment on the Securities

Whether the Securities are automatically called on the Call Date for the Call Premium will be determined based on the closing value of the Lowest Performing Underlying on the Call Date as follows:

If the Securities are not automatically called, then on the Maturity Date, you will receive a cash payment per Security (the Maturity Payment Amount) calculated as follows:

PS-9

Market Linked Securities— Auto-Callable with Leveraged Upside Participation and Contingent Downside

Selected Risk Considerations

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

Structure-related Risks

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

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

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

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

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

Because the Securities are linked to the lowest performing (and not the average performance) of the Underlyings, you may not receive any return on the Securities and may lose a significant portion or all of your principal amount even if the closing value of one Underlying is always greater than or equal to its Starting Value or Threshold Value. Your Securities are linked to the lowest performing of the Underlyings, and a change in the value of one Underlying may not correlate with changes in the value of the other Underlyings. The Securities are not linked to a basket composed of the Underlyings, where the depreciation in the value of one Underlying could be offset to some extent by the appreciation in the value of the other Underlyings. In the case of the Securities, the individual performance of each Underlying would not be combined, and the depreciation in the value of one Underlying would not be offset by any appreciation in the value of the other Underlyings. Even if the closing value of an Underlying is at or above its Starting Value on the Call Date, the Securities will not be automatically called, and you will not receive the Call Premium on the Call Date, if the closing value of another Underlying is below its Starting Value on that day. In addition, even if the Ending Value of an Underlying is at or above its Threshold Value, you will lose a significant portion or all of your principal if the Ending Value of the Lowest Performing Underlying is below its Threshold Value.

Your return on the Securities may be less than the yield on a conventional debt security of comparable maturity. Any return that you receive on the Securities may be less than the return you would earn if you purchased a conventional debt security with the

PS-10

Market Linked Securities— Auto-Callable with Leveraged Upside Participation and Contingent Downside

same Maturity Date. As a result, your investment in the Securities may not reflect the full opportunity cost to you when you consider factors, such as inflation, that affect the time value of money.

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

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

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

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

Valuation- and Market-related Risks

The public offering price you pay for the Securities will exceed their initial estimated value. The range of initial estimated values of the Securities that is provided on the cover page of this preliminary pricing supplement, and the initial estimated value as of the Pricing Date that will be provided in the final pricing supplement, are each estimates only, determined as of a particular point in time by reference to our and our affiliates’ pricing models. These pricing models consider certain assumptions and variables, including our credit spreads and those of the Guarantor, the Guarantor’s internal funding rate, mid-market terms on hedging transactions, expectations on interest rates, dividends and volatility, price-sensitivity analysis, and the expected term of the Securities. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. If you attempt to sell the Securities prior to maturity, their market value may be lower than the price you paid for them and lower than their initial estimated value. This is due to, among other things, changes in the values 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 Securities" below. These factors, together with various credit, market and economic factors over the term of the Securities, are expected to reduce the price at which you may be able to sell the Securities in any secondary market and will affect the value of the Securities in complex and unpredictable ways.

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

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

The Securities are not designed to be short-term trading instruments, and if you attempt to sell the Securities prior to maturity, their market value, if any, will be affected by various factors that interrelate in complex ways, and their market value may be less than the principal amount. The following factors are expected to affect the value of the Securities: values of the

Underlyings at such time; volatility of the Underlyings; economic and other conditions generally; interest rates; dividend yields; exchange rate movements and volatility; our and the Guarantor’s financial condition and creditworthiness; and time to maturity.

Conflict-related Risks

Trading and hedging activities by us, the Guarantor and any of our other affiliates, including BofAS, and WFS and its affiliates, may create conflicts of interest with you and may affect your return on the Securities and their market value. We, the Guarantor or one or more of our other affiliates, including BofAS, and WFS and its affiliates, may buy or sell shares of the Underlying Stock or the securities included in the Indices, as applicable, 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. While we, the Guarantor or one or more of our other affiliates, including BofAS, and WFS and its affiliates, may from time to time own shares of the Underlying Stock or the securities represented by the Indices, except to the extent that BAC’s or Wells Fargo & Company’s (the parent company of WFS) common stock may be included in the Indices, as applicable, we, the Guarantor and our other affiliates, including BofAS, and WFS and its affiliates, do not control the issuer of the Underlying Stock (the “Underlying Stock Issuer”) or any company included in the Indices, and have not verified any disclosure made by any other company. We, the Guarantor or one or more of our other affiliates, including BofAS, or WFS and its affiliates, may execute such purchases or sales for our own or their own accounts, for business reasons, or in connection with hedging our obligations under the Securities. These transactions may present a conflict of interest between your interest in the Securities and the interests we, the Guarantor and our other affiliates, including BofAS, and WFS and its affiliates, may have in our or their proprietary accounts, in facilitating transactions, including block trades, for our or their other customers, and in accounts under our or their management. These transactions may adversely affect the values of the Underlyings in a manner that could be adverse to your investment in the Securities. On or before the Pricing Date, any purchases or sales by us, the Guarantor or our other affiliates, including BofAS or others on its behalf, and WFS and its affiliates (including for the purpose of hedging some or all of our anticipated exposure in connection with the Securities), may affect the values of the Underlyings. Consequently, the values of the Underlyings may change subsequent to the Pricing Date, which may adversely affect the market value of the Securities.

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

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

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

Hypothetical Examples and Returns

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

Hypothetical Call Premium:	22.00% of the principal amount (the lowest possible Call Premium that may be determined on the Pricing Date)
Upside Participation Rate:	150.00%
Hypothetical Starting Value:	For each Underlying, 100.00
Hypothetical Threshold Value:	For each Underlying, 75.00 (75% of its hypothetical Starting Value)

⁽¹⁾ The Performance Factor of the Lowest Performing Underlying on the Final Calculation Day is equal to its Ending Value divided by its Starting Value (expressed as a percentage).

Hypothetical Examples Of Payment Upon Automatic Call Or At Maturity

Example 1. The closing value of the Lowest Performing Underlying on the Call Date is greater than its Starting Value, and the Securities are automatically called on the Call Date:

	S&P 500^® Index	Dow Jones Industrial Average^®	Common Stock of Microsoft Corporation
Hypothetical Starting Value:	100.00	100.00	$100.00
Hypothetical closing value on the Call Date:	180.00	170.00	$160.00
Performance Factor on the Call Date (closing value on the Call Date *divided by* Starting Value):	180.00%	170.00%	160.00%

Step 1: Determine which Underlying is the Lowest Performing Underlying on the Call Date.

In this example, the common stock of Microsoft Corporation has the lowest Performance Factor on the Call Date and is, therefore, the Lowest Performing Underlying on the Call Date.

Step 2: Determine the payment upon automatic call.

Because the hypothetical closing value of the Lowest Performing Underlying on the Call Date is greater than its hypothetical Starting Value, the Securities are automatically called on the Call Date and you will receive on the Call Settlement Date the principal amount of your Securities plus a Call Premium of 22.00% of the principal amount. Even though the Lowest Performing Underlying

PS-15

Market Linked Securities— Auto-Callable with Leveraged Upside Participation and Contingent Downside

appreciated by 60.00% from its Starting Value to its closing value on the Call Date in this example, your return is limited to the Call Premium of 22.00%.

On the Call Settlement Date, you would receive $1,220.00 per Security.

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

	S&P 500^® Index	Dow Jones Industrial Average^®	Common Stock of Microsoft Corporation
Hypothetical Starting Value:	100.00	100.00	$100.00
Hypothetical closing value on the Call Date:	75.00	110.00	$110.00
Hypothetical Ending Value:	120.00	130.00	$130.00
Hypothetical Threshold Value:	75.00, which is 75% of the hypothetical Starting Value	75.00, which is 75% of the hypothetical Starting Value	$75.00, which is 75% of the hypothetical Starting Value
Performance Factor on the Call Date (closing value on the Call Date *divided by* Starting Value):	75.00%	110.00%	110.00%
Performance Factor on the Final Calculation Day (closing value on the Final Calculation Day *divided by* Starting Value):	120.00%	130.00%	130.00%
Hypothetical Underlying Return (Ending Value - Starting Value)/Starting Value:	20.00%	30.00%	30.00%

Step 1: Determine which Underlying is the Lowest Performing Underlying on the Final Calculation Day.

In this example, the S&P 500^® Index has the lowest Performance Factor on the Final Calculation Day and is, therefore, the Lowest Performing Underlying on the Final Calculation Day.

Step 2: Determine the Maturity Payment Amount based on the Underlying Return of the Lowest Performing Underlying on the Final Calculation Day.

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

$1,000 × Underlying Return of the Lowest Performing Underlying × Upside Participation Rate

$1,000 × 20.00% × 150.00%

= $300.00

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

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

	S&P 500^® Index	Dow Jones Industrial Average^®	Common Stock of Microsoft Corporation
Hypothetical Starting Value:	100.00	100.00	$100.00
Hypothetical closing value on the Call Date:	75.00	110.00	$110.00
Hypothetical Ending Value:	95.00	130.00	$130.00
Hypothetical Threshold Value:	75.00, which is 75% of the hypothetical Starting Value	75.00, which is 75% of the hypothetical Starting Value	$75.00, which is 75% of the hypothetical Starting Value
Performance Factor on the Call Date (closing value on the Call Date *divided by* Starting Value):	75.00%	110.00%	110.00%

PS-16

Market Linked Securities— Auto-Callable with Leveraged Upside Participation and Contingent Downside

Performance Factor on the Final Calculation Day (closing value on the Final Calculation Day *divided by* Starting Value):	95.00%	130.00%	130.00%
Hypothetical Underlying Return (Ending Value - Starting Value)/Starting Value:	-5.00%	30.00%	30.00%

Step 1: Determine which Underlying is the Lowest Performing Underlying on the Final Calculation Day.

In this example, the S&P 500^® Index has the lowest Performance Factor on the Final Calculation Day and is, therefore, the Lowest Performing Underlying on the Final Calculation Day.

Step 2: Determine the Maturity Payment Amount based on the Underlying Return of the Lowest Performing Underlying on the Final Calculation Day.

Because the hypothetical closing value of the Lowest Performing Underlying on the Call Date is less than its hypothetical Starting Value, the Securities are not automatically called. Because the hypothetical Ending Value of the Lowest Performing Underlying is less than its hypothetical Starting Value, but not by more than 25%, you would receive the principal amount of your Securities at maturity.

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

Example 4. The Securities are not automatically called. The Ending Value of the Lowest Performing Underlying is less than its Threshold Value and the Maturity Payment Amount is less than the principal amount:

	S&P 500^® Index	Dow Jones Industrial Average^®	Common Stock of Microsoft Corporation
Hypothetical Starting Value:	100.00	100.00	$100.00
Hypothetical closing value on the Call Date:	75.00	110.00	$110.00
Hypothetical Ending Value:	50.00	130.00	$130.00
Hypothetical Threshold Value:	75.00, which is 75% of the hypothetical Starting Value	75.00, which is 75% of the hypothetical Starting Value	$75.00, which is 75% of the hypothetical Starting Value
Performance Factor on the Call Date (closing value on the Call Date *divided by* Starting Value):	75.00%	110.00%	110.00%
Performance Factor on the Final Calculation Day (closing value on the Final Calculation Day *divided by* Starting Value)	50.00%	130.00%	130.00%
Hypothetical Underlying Return (Ending Value - Starting Value)/Starting Value:	-50.00%	30.00%	30.00%

Step 1: Determine which Underlying is the Lowest Performing Underlying on the Final Calculation Day.

In this example, the S&P 500^® Index has the lowest Performance Factor on the Final Calculation Day and is, therefore, the Lowest Performing Underlying on the Final Calculation Day.

Step 2: Determine the Maturity Payment Amount based on the Underlying Return of the Lowest Performing Underlying on the Final Calculation Day.

Because the hypothetical closing value of the Lowest Performing Underlying on the Call Date is less than its hypothetical Starting Value, the Securities are not automatically called. Because the hypothetical Ending Value of the Lowest Performing Underlying is less than its hypothetical Starting Value by more than 25%, you would lose a portion of the principal amount of your Securities and would be paid a Maturity Payment Amount equal to:

$1,000 + ($1,000 × Underlying Return of the Lowest Performing Underlying)

$1,000 + ($1,000 × -50.00%)

= $500.00

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

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.

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 Securities 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 Securities.

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

PS-18

Market Linked Securities— Auto-Callable with Leveraged Upside Participation and Contingent Downside

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.

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 2, 2020 through October 7, 2025. We obtained this historical data from Bloomberg L.P. We have not independently verified the accuracy or completeness of the information obtained from Bloomberg L.P. The horizontal line in the graph represents the SPX’s hypothetical Threshold Value of 5,035.9425, which is 75% of the SPX’s hypothetical Starting Value of 6,714.59, which was its closing level on October 7, 2025. The actual Starting Value and Threshold Value will be determined on the Pricing Date.

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

Before investing in the Securities, you should consult publicly available sources for the levels of the SPX.

The Dow Jones Industrial Average^®

Unless otherwise stated, all information on the INDU provided in this pricing supplement is derived from Dow Jones Indexes, the marketing name and a licensed trademark of SPDJI. The INDU is a price-weighted index, which means an underlying stock’s weight in the INDU is based on its price per share rather than the total market capitalization of the issuer. The INDU is designed to provide an indication of the composite performance of 30 common stocks of corporations representing a broad cross-section of U.S. industry. The corporations represented in the INDU tend to be market leaders in their respective industries and their stocks are typically widely held by individuals and institutional investors.

The INDU is maintained by an Averages Committee comprised of three representatives of SPDJI and two representatives of The Wall Street Journal (the “WSJ”). Generally, composition changes occur only after mergers, corporate acquisitions or other dramatic shifts in a component's core business. When such an event necessitates that one component be replaced, the entire INDU is reviewed. As a result, when changes are made they typically involve more than one component. While there are no rules for component selection, a stock typically is added only if it has an excellent reputation, demonstrates sustained growth, is of interest to a large number of investors and accurately represents the sector(s) covered by the average.

Changes in the composition of the INDU are made entirely by the Averages Committee without consultation with the corporations represented in the INDU, any stock exchange, any official agency or us. Unlike most other indices, which are reconstituted according to a fixed review schedule, constituents of the INDU are reviewed on an as-needed basis. Changes to the common stocks included in the INDU tend to be made infrequently, and the underlying stocks of the INDU may be changed at any time for any reason. The companies currently represented in the INDU are incorporated in the United States and its territories and their stocks are listed on the New York Stock Exchange and The Nasdaq Stock Market.

The INDU initially consisted of 12 common stocks and was first published in the WSJ in 1896. The INDU was increased to include 20 common stocks in 1916 and to include 30 common stocks in 1928. The number of common stocks in the INDU has remained at 30 since 1928, and, in an effort to maintain continuity, the constituent corporations represented in the INDU have been changed on a relatively infrequent basis. The INDU includes companies from nine main groups: Basic Materials; Consumer Goods; Consumer Services; Financials; Healthcare; Industrials; Oil & Gas; Technology; and Telecommunications.

Computation of the INDU

The level of the INDU is the sum of the primary exchange prices of each of the 30 component stocks included in the INDU, divided by a divisor that is designed to provide a meaningful continuity in the level of the INDU. Because the INDU is price-weighted, stock splits or changes in the component stocks could result in distortions in the INDU level. In order to prevent these distortions related to extrinsic factors, the divisor is periodically changed in accordance with a mathematical formula that reflects adjusted proportions within the INDU. The current divisor of the INDU is published daily in the WSJ and other publications. In addition, other statistics based on the INDU may be found in a variety of publicly available sources.

Structuring the Securities

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

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

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

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

U.S. Federal Income Tax Summary

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

•	There is no statutory, judicial, or administrative authority directly addressing the characterization of the Securities.

•

You agree with us (in the absence of an administrative determination, or judicial ruling to the contrary) to characterize and treat the Securities for all tax purposes as single financial contracts with respect to the Underlyings. In the opinion of Sidley Austin LLP, our tax counsel, the U.S. federal income tax characterization and treatment of the Securities described herein is a reasonable interpretation of current law.

•

Under this characterization and tax treatment of the Securities, a U.S. Holder (as defined on page 71 of the accompanying prospectus) generally will recognize capital gain or loss upon maturity or upon a sale, exchange or redemption of the Securities. This capital gain or loss generally will be long-term capital gain or loss if you held the Securities for more than one year.

•	No assurance can be given that the Internal Revenue Service (“IRS”) or any court will agree with this characterization and tax treatment.

•

Under current IRS guidance, withholding on “dividend equivalent” payments (as discussed in the accompanying product supplement), if any, will not apply to Securities that are issued as of the date of this pricing supplement unless such Securities are “delta-one” instruments. Based on our determination that the Securities are not delta-one instruments, Non-U.S. Holders should not be subject to withholding on dividend equivalent payments, if any, under the Securities.

•

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, the Securities are 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 the Securities.

You should consult your own tax advisor concerning the U.S. federal income tax consequences to you of acquiring, owning, and disposing of the Securities, as well as any tax consequences arising under the laws of any state, local, foreign, or other tax jurisdiction and the possible effects of changes in U.S. federal or other tax laws. You should review carefully the discussion under the section entitled “U.S. Federal Income Tax Summary” beginning on page PS-36 of the accompanying product supplement.
