Fully and Unconditionally Guaranteed by Bank of America Corporation

Principal at Risk Securities

This document provides a summary of the terms of the securities. Investors must carefully review the accompanying preliminary pricing supplement referenced below, product supplement, prospectus supplement and prospectus, and the “Risk Considerations” on the following page, prior to making an investment decision.

The securities do not guarantee the repayment of principal and do not provide for the regular payment of interest. Investors will not participate in any appreciation in any underlying index. The securities are for investors who are willing to risk their principal and seek an opportunity to earn contingent quarterly coupon payments at a potentially above-market rate in exchange for the risk of receiving no contingent quarterly coupon payments if any underlying index closes below the coupon barrier level for such index on any index business day during the related observation period, and the risk of an early redemption of the securities at our discretion. The securities are our senior debt securities. Any payments on the securities are fully and unconditionally guaranteed by Bank of America Corporation (“BAC”). The securities are issued as part of BofA Finance LLC’s (“BofA Finance”) “Medium-Term Notes, Series A” program.

SUMMARY TERMS
Issuer:	BofA Finance
Guarantor:	BAC
Underlying indices:	S&P 500^® Index (Bloomberg symbol: “SPX”), Russell 2000^® Index (Bloomberg symbol: “RTY”) and NASDAQ-100 Index^® (Bloomberg symbol: “NDX”)
Stated principal amount:	$1,000.00 per security
Issue price:	$1,000.00 per security
Pricing date:	October 2, 2026
Original issue date:	October 7, 2026 (3 business days after the pricing date)
Maturity date:	October 5, 2028
Call feature:	Beginning on January 7, 2027, on any quarterly redemption date, we have the right to redeem all (but not less than all) of the securities for a redemption payment equal to the stated principal amount plus any contingent quarterly coupon otherwise due with respect to the relevant observation period. We will give notice to the trustee at least five business days but not more than 60 calendar days before the applicable redemption date. No further payments will be made on the securities once they have been redeemed.
Contingent quarterly coupon:	If, on each index business day during an observation period, the index closing value of each underlying index is greater than or equal to its respective coupon barrier level, we will pay a contingent quarterly coupon of at least $20.00 per security (equal to a rate of at least 2.00% per quarter or at least 8.00% per annum) on the related coupon payment date. The actual contingent quarterly coupon will be determined on the pricing date. If, on any index business day during an observation period, the index closing value of any underlying index is less than the coupon barrier level for such index, no contingent quarterly coupon will be paid with respect to that observation period. It is possible that one or more underlying indices will close below the respective coupon barrier level(s) on any index business day during most or all of the observation periods throughout the entire term of the securities so that you will receive few or no contingent quarterly coupons.

Payment at maturity:	If the securities have not previously been redeemed, investors will receive on the maturity date a payment at maturity determined as follows: If the final index value of each underlying index is greater than or equal to its respective downside threshold level: the stated principal amount and, if payable, the contingent quarterly coupon otherwise due with respect to the final observation period. If the final index value of any underlying index is less than its respective downside threshold level: (i) the stated principal amount multiplied by (ii) the index performance factor of the worst performing underlying index. Under these circumstances, the payment at maturity will be less than 60% of the stated principal amount of the securities and could be zero.
Redemption payment:	The redemption payment will be an amount equal to (i) the stated principal amount plus (ii) any contingent quarterly coupon otherwise due with respect to the related observation period.
Initial index value:	For each underlying index, the index closing value on the pricing date.
Final index value:	For each underlying index, the index closing value on the final observation date.
Worst performing underlying index:	The underlying index with the largest percentage decrease from the respective initial index value to the respective final index value.
Index performance factor:	With respect to each underlying index, final index value divided by the initial index value
Redemption dates:	Quarterly. See “Observation Period End-Dates, Coupon Payment Dates and Redemption Dates” below.
Observation period end-dates:	Quarterly, as set forth under “Observation Period End-Dates, Coupon Payment Dates and Redemption Dates” below, subject to postponement as set forth in “Description of the Notes—Certain Terms of the Notes—Events Relating to Observation Dates” beginning on page PS-18 of the accompanying product supplement, with references therein to “Observation Date” to be read as references to “Observation Period End-Date.”

Risk Considerations

The risks set forth below are discussed in more detail in the “Risk Factors” section in the accompanying preliminary pricing supplement. Please review those risk factors carefully prior to making an investment decision.

Structure-related Risks

▪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 quarterly coupons, if any, over the term of the securities.

▪The securities are subject to early redemption, which would limit your ability to receive the contingent quarterly coupons over the full term of the securities

▪You may not receive any contingent quarterly coupons.

▪Your return on the securities may be less than the yield on a conventional debt security of comparable maturity.

▪The payment at maturity will not reflect changes in the levels of the underlying indices other than on the final observation date.

▪Because the securities are linked to the worst performing (and not the average performance) of the underlying indices, you may not receive any return on the securities and may lose a significant portion or all of your investment in the securities even if the index closing value or final index value of one underlying index is greater than or equal to its coupon barrier level or downside threshold level, as applicable.

▪Any payments on the securities are subject to our credit risk and the credit risk of the guarantor, and any actual or perceived changes in our or the guarantor’s creditworthiness are expected to affect the value of, or any amounts payable on, the securities.

▪We are a finance subsidiary and, as such, have no independent assets, operations, or revenues.

Valuation- and Market-related Risks

▪The price to public 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 we, BAC, BofAS or any of our other affiliates would be willing to purchase your securities in any secondary market (if any exists) at any time.

▪We cannot assure you that a trading market for your securities will ever develop or be maintained.

Conflict-related Risks

▪Trading and hedging activities by us, the guarantor and any of our other affiliates, including BofAS, may create conflicts of interest with you and may adversely 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.

Underlying Index-related Risks

▪The securities are subject to risks associated with small-size capitalization companies.

▪The securities are subject to risks associated with foreign securities markets.

▪Governmental regulatory actions, such as sanctions, could adversely affect your investment in the securities.

▪The publisher of an underlying index may adjust that underlying index in a way that affects its levels, and the publisher has no obligation to consider your interests.

Tax-related Risks

▪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.

Tax Considerations

You should review carefully the discussion in the accompanying preliminary pricing supplement under the caption “Additional Information About the Securities—Tax considerations” concerning the U.S. federal income tax consequences of an investment in the securities, and you should consult your tax adviser.
