Description of Terms
●   
Linked to the lowest performing of the SPDR® S&P® Regional Banking ETF, the Russell 2000® Index and the Nasdaq-100 Index®
●   
Unlike ordinary debt securities, the Securities do not provide for fixed payments of interest, do not repay a fixed amount of principal on the Maturity Date and are subject to potential automatic call prior to the Maturity Date upon the terms described below. Whether the Securities pay a Contingent Coupon, whether the Securities are automatically called prior to the Maturity Date and, if they are not automatically called, whether you are repaid the principal amount of your Securities on the Maturity Date will depend in each case on the closing value of the Lowest Performing Underlying on the relevant Observation Date. The Lowest Performing Underlying on any Observation Date is the Underlying that has the lowest closing value on that Observation Date as a percentage of its Starting Value
●   
Contingent Coupon.  The Securities will pay a Contingent Coupon Payment on a quarterly basis until the earlier of the Maturity Date or automatic call if, and only if, the closing value of the Lowest Performing Underlying on the Observation Date for that quarter is greater than or equal to its Coupon Barrier. However, if the closing value of the Lowest Performing Underlying on an Observation Date is less than its Coupon Barrier, you will not receive any Contingent Coupon Payment for the relevant quarter. If the closing value of the Lowest Performing Underlying is less than its Coupon Barrier on every Observation Date, you will not receive any Contingent Coupon Payments throughout the entire term of the Securities. The Coupon Barrier for each Underlying is equal to 70% of its Starting Value. The Contingent Coupon Rate will be determined on the Pricing Date and will be within the range of 8.50% to 9.50% per annum
●   
Automatic Call. If the closing value of the Lowest Performing Underlying on any of the quarterly Observation Dates from June 2022 to September 2024, inclusive, is greater than or equal to its Starting Value, we will automatically call the Securities for the principal amount plus a final Contingent Coupon Payment
●   
Potential Loss of Principal. If the Securities are not automatically called prior to the Maturity Date, you will receive the principal amount on the Maturity Date if, and only if, the closing value of the Lowest Performing Underlying on the Valuation Date is greater than or equal to its Threshold Value. If the closing value of the Lowest Performing Underlying on the Valuation Date is less than its Threshold Value, you will lose more than 30%, and possibly all, of the principal amount of your Securities. The Threshold Value for each Underlying is equal to 70% of its Starting Value
●   
If the Securities are not automatically called prior to the Maturity Date, you will have full downside exposure to the Lowest Performing Underlying from its Starting Value if its closing value on the Valuation Date is less than its Threshold Value, but you will not participate in any appreciation of any Underlying and will not receive any dividends on shares of the Fund or the securities held by or included in any Underlying
●   
Your return on the Securities will depend solely on the performance of the Underlying that is the Lowest Performing Underlying on each Observation Date. 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
●   
All payments on the Securities are subject to the credit risk of BofA Finance LLC, as issuer and Bank of America Corporation, as guarantor, and you will have no ability to pursue shares of the Fund or any securities held by or included in any Underlying for payment; if BofA Finance LLC, as issuer, and Bank of America Corporation, as guarantor, default on their obligations, you could lose some or all of your investment
●   
No exchange listing; designed to be held to maturity


*Subject to change.
The initial estimated value of the Securities as of the pricing date is expected to be between $910.00 and $960.00 per Security, which is less than the public offering price. The actual value of your Securities at any time will reflect many factors and cannot be predicted with accuracy. See “Risk Factors” beginning on page PS-9 of the accompanying preliminary pricing supplement and “Structuring the Securities” on page PS-35 of the accompanying preliminary 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. Potential purchasers of the Securities should consider the information in “Risk Factors” beginning on page PS-9 of the accompanying preliminary pricing supplement, page PS-5 of the accompanying product supplement, page S-5 of the accompanying prospectus supplement, and page 7 of the accompanying prospectus. 
This introductory term sheet does not provide all of the information that an investor should consider prior to making an investment decision. 
Investors should carefully review the accompanying preliminary pricing supplement, product supplement, prospectus supplement and prospectus before making a decision to invest in the Securities.  
NOT A BANK DEPOSIT AND NOT INSURED OR GUARANTEED BY THE FDIC OR ANY OTHER GOVERNMENTAL AGENCY
 
How The Lowest Performing Underlying Is Determined
The Lowest Performing Underlying on any Observation Date is the Underlying with the lowest performance factor on that Observation Date.
The performance factor, with respect to an Underlying on any Observation Date, will be its closing value on such Observation Date divided by its Starting Value (expressed as a percentage).
How Contingent Coupon Payments Are Calculated
On each quarterly Contingent Payment Date, you will receive a Contingent Coupon Payment at a per annum rate equal to the Contingent Coupon Rate if, and only if, the closing value of the Lowest Performing Underlying on the related Observation Date is greater than or equal to its Coupon Barrier. 
If the closing value of the Lowest Performing Underlying on any Observation Date is less than its Coupon Barrier, you will not receive any Contingent Coupon Payment on the related Contingent Payment Date. If the closing value of the Lowest Performing Underlying is less than its Coupon Barrier on all quarterly Observation Dates, you will not receive any Contingent Coupon Payments over the term of the Securities.
Each quarterly Contingent Coupon Payment, if any, will be calculated per Security as follows:
The Contingent Coupon Rate will be determined on the Pricing Date and will be within the range of [8.50%-9.50%] per annum. Any Contingent Coupon Payments will be rounded to the nearest cent, with one-half cent rounded upward.
How To Determine If The Securities Will Be Automatically Called
If the closing value of the Lowest Performing Underlying on any of the quarterly Observation Dates from June 2022 to September 2024, inclusive, is greater than or equal to its Starting Value, the Securities will be automatically called, and on the related Call Settlement Date you will be entitled to receive a cash payment per Security equal to the principal amount per Security plus a final Contingent Coupon Payment. The Securities will not be subject to automatic call until the second quarterly Observation Date, which is approximately six months after the Issue Date. 
                                         
If the Securities are automatically called, they will cease to be outstanding on the related Call Settlement Date and you will have no further rights under the Securities after such Call Settlement Date. 
How The Redemption Amount Is Calculated
If the Securities are not automatically called prior to the Maturity Date, you will receive on the Maturity Date a cash payment per Security equal to the Redemption Amount (in addition to the final Contingent Coupon Payment, if any). The Redemption Amount per Security will equal:
       
●   
If the Ending Value of the Lowest Performing Underlying on the Valuation Date is greater than or equal to its Threshold Value: $1,000; or 
●   
If the Ending Value of the Lowest Performing Underlying on the Valuation Date is less than its Threshold Value:

If the Securities are not automatically called prior to maturity and the Ending Value of the Lowest Performing Underlying on the Valuation Date is less than its Threshold Value, you will lose more than 30%, and possibly all, of the principal amount of your Securities at maturity. 
Any return on the Securities will be limited to the sum of your Contingent Coupon Payments, if any. You will not participate in any appreciation of any Underlying, but you will have full downside exposure to decreases in the value of the Lowest Performing Underlying on the Valuation Date if the Ending Value of that Underlying is less than its Threshold Value.

Hypothetical Payout Profile

The profile to the right illustrates the potential maturity payment amount on the Securities (excluding the final Contingent Coupon Payment, if any) for a range of hypothetical performances of the Lowest Performing Underlying on the Valuation Date from its Starting Value to its Ending Value, assuming the Securities have not been automatically called prior to the Maturity Date. 
This graph has been prepared for purposes of illustration only. Your actual return will depend on the actual Ending Value of the Lowest Performing Underlying on the Valuation Date and whether you hold your Securities to maturity. The performance of the better performing Underlyings is not relevant to your return on the Securities.


 
Hypothetical Returns 

If the Securities are automatically called: If the Securities are automatically called prior to maturity, you will receive the principal amount of your Securities plus a final Contingent Coupon Payment on the Call Settlement Date. In the event the Securities are automatically called, your total return on the Securities will equal any Contingent Coupon Payments received prior to the Call Settlement Date and the Contingent Coupon Payment received on the Call Settlement Date.

If the Securities are not automatically called:

If the Securities are not automatically called prior to maturity, the following table illustrates, for a range of hypothetical performance factors of the Lowest Performing Underlying on the Valuation Date, the hypothetical Redemption Amount payable at maturity per Security (excluding the final Contingent Coupon Payment, if any). The performance factor of the Lowest Performing Underlying on the Valuation Date is its Ending Value expressed as a percentage of its Starting Value (i.e., its Ending Value divided by its Starting Value).

The above figures do not take into account Contingent Coupon Payments, if any, received during the term of the Securities. As evidenced above, in no event will you have a positive rate of return based solely on the Redemption Amount received at maturity; any positive return will be based solely on the Contingent Coupon Payments, if any, received during the term of the Securities. Each Security has a principal amount of $1,000.
The above figures are for purposes of illustration only and may have been rounded for ease of analysis. If the Securities are not automatically called prior to maturity, the actual amount you will receive at maturity will depend on the actual Ending Value of the Lowest Performing Underlying on the Valuation Date. The performance of the better performing Underlyings is not relevant to your return on the Securities.
For historical data regarding the closing values of the Underlyings, see the historical information set forth under the sections titled “The SPDR® S&P® Regional Banking ETF,” “The Russell 2000® Index” and “The Nasdaq-100 Index®” in the accompanying preliminary pricing supplement.

Selected Risk Considerations 
The risks set forth below, as well as additional risks related to this investment, are discussed in detail in the “Risk Factors” section in the accompanying preliminary pricing supplement.  Please review those risk disclosures carefully.
●   
Your investment may result in a loss; there is no guaranteed return of principal.
●   
Your return on the Securities is limited to the return represented by the Contingent Coupon Payments, if any, over the term of the Securities. 
●   
The Securities are subject to a potential automatic call, which would limit your ability to receive the Contingent Coupon Payments over the full term of the Securities.
●   
You may not receive any Contingent Coupon Payments. 
●   
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 Coupon Barrier or Threshold Value, as applicable. 
●   
Higher Contingent Coupon Rates are associated with greater risk.
●   
Your return on the Securities may be less than the yield on a conventional debt security of comparable maturity. 
●   
The Contingent Coupon Payment, payment upon automatic call or Redemption Amount, as applicable, will not reflect the values of the Underlyings other than on the Observation Dates.
●   
Any payment on the Securities is subject to the credit risk of BofA Finance, as issuer, and BAC, as Guarantor, and actual or perceived changes in BofA Finance or the Guarantor’s creditworthiness are expected to affect the value of the Securities.  
●   
We are a finance subsidiary and, as such, have no independent assets, operations or revenues.
●   
The public offering price you pay for the Securities will exceed their initial estimated value. 
●   
The initial estimated value does not represent a minimum or maximum price at which BofA Finance, 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. 
●   
BofA Finance cannot assure you that a trading market for your Securities will ever develop or be maintained. 
●   
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. 
●   
Trading and hedging activities by BofA Finance, 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. 
●   
There may be potential conflicts of interest involving the calculation agent, which is an affiliate of ours.
●   
The Securities are subject to risks associated with the banking industry.
●   
The stocks held by the KRE are concentrated in one sector.
●   
The anti-dilution adjustments will be limited.
●   
The performance of the KRE may not correlate with the performance of its underlying index as well as the net asset value per share of the KRE, especially during periods of market volatility.  
●   
The publisher of an Index or the sponsor or investment advisor of the Fund may adjust the applicable Underlying in a way that affects its values, and the publisher, sponsor or investment advisor has no obligation to consider your interests.
●   
The Securities are subject to risks associated with small-size capitalization companies. 
●   
An Investment In The Securities Is Subject To Risks Associated With Investing In Non-U.S. Companies.
●   
The U.S. federal income tax consequences of an investment in the Securities are uncertain, and may be adverse to a holder of the Securities. 
Investment suitability must be determined individually for each investor. The Securities described herein are not an appropriate investment for all investors. In particular, no investor should purchase the Securities unless they understand and are able to bear the associated market, liquidity and yield risks. Unless market conditions and other relevant factors change significantly in your favor, a sale of the Securities prior to maturity is likely to result in sale proceeds that are substantially less than the principal amount per Security. BofAS, Wells Fargo Securities and their affiliates are not obligated to purchase the Securities from you at any time prior to maturity.  
You may revoke your offer to purchase the Securities at any time prior to the time at which we accept such offer on the date the Securities are priced. We reserve the right to change the terms of, or reject any offer to purchase, the Securities prior to their issuance. In the event of any changes to the terms of the Securities, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes in which case we may reject your offer to purchase. Please see the accompanying preliminary pricing supplement for complete product disclosure, including related risks and tax disclosure.
