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 of the underlying shares. 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 of the underlying shares closes below its respective coupon barrier level on the observation dates, and the risk of an automatic early redemption of the securities. Investors will not participate in any appreciation in any of the underlying shares. 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 shares:	The Consumer Staples Select Sector SPDR® Fund (Bloomberg symbol: “XLP”), the Energy Select Sector SPDR® Fund (Bloomberg symbol: “XLE”) and the Health Care Select Sector SPDR® Fund (Bloomberg symbol “XLV”)
Stated principal amount:	$1,000.00 per security
Issue price:	$1,000.00 per security
Pricing date:	May 12, 2023
Original issue date:	May 17, 2023 (3 business days after the pricing date).
Maturity date:	May 15, 2026
Early redemption:	The securities are not subject to automatic early redemption until three months after the original issue date. Following this 3-month initial non-call period, if, on any redemption determination date, beginning on August 14, 2023, the determination closing price of each of the underlying shares is greater than or equal to its respective initial share price, the securities will be automatically redeemed for an early redemption payment on the related early redemption date. No further payments will be made on the securities once they have been redeemed. The securities will not be redeemed early on any early redemption date if the determination closing price of any of the underlying shares is below the respective initial share price for such underlying shares on the related redemption determination date.
Early redemption payment:	The early redemption payment will be an amount equal to (i) the stated principal amount plus (ii) the contingent quarterly coupon with respect to the related observation date.
Determination closing price:	With respect to each of the underlying shares, its closing price on any redemption determination date or observation date (other than the final observation date) times the adjustment factor for such underlying shares on such redemption determination date or observation date, as applicable.
Contingent quarterly coupon:	·If, on any observation date, the determination closing price of each of the underlying shares is greater than or equal to its respective coupon barrier level, we will pay a contingent quarterly coupon of at least $27.375 per security (equal to a rate of at least 2.7375% per quarter or at least 10.95% per annum) on the related coupon payment date. The actual contingent quarterly coupon will be determined on the pricing date. ·If, on any observation date, the determination closing price of any of the underlying shares is less than its respective coupon barrier level, no contingent quarterly coupon will be paid with respect to that observation date. It is possible that one or more underlying shares will close below the respective coupon barrier level(s) on most or all of the observation dates 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 share price of each of the underlying shares is greater than or equal to its respective downside threshold level: the stated principal amount and the contingent quarterly coupon otherwise due with respect to the final observation date. If the final share price of any of the underlying shares is less than its respective downside threshold level: (i) the stated principal amount multiplied by (ii) the share performance factor of the worst performing of the underlying shares. Under these circumstances, the payment at maturity will be less than 60% of the stated principal amount of the securities and could be zero.
Initial share price:	With respect to each of the underlying shares, its closing price on the pricing date.
Final share price:	With respect to each of the underlying shares, its closing price on the final observation date times the adjustment factor for such underlying shares on such date
Worst performing of the underlying shares:	The underlying shares with the largest percentage decrease from its respective initial share price to its respective final share price
Share performance factor:	With respect to each of the underlying shares, its final share price divided by its initial share price
Adjustment factor:	With respect to each of the underlying shares, 1.0, subject to adjustment in the event of certain events affecting such underlying shares as described in “Description of the Notes—Anti-Dilution and Discontinuance Adjustments Relating to ETFs” beginning on page PS-28 of the accompanying product supplement.
Observation dates:	Quarterly, as set forth under “Observation Dates, Redemption Determination Dates, Coupon Payment Dates and Early 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-23 of the accompanying product supplement.
Coupon payment dates:	Quarterly, as set forth under “Observation Dates, Redemption Determination Dates, Coupon Payment Dates and Early Redemption Dates” below.
Downside threshold level:	With respect to each of the underlying shares, 60% of the initial share price for such underlying shares
CUSIP / ISIN:	09709VWG7 / US09709VWG75
Listing:	The securities will not be listed on any securities exchange.
Estimated value on the pricing date:	Expected to be between $915.00 and $965.00 per $1,000 in principal amount of securities. See “Structuring the securities” in the preliminary pricing supplement.

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 contingent quarterly coupons, early redemption payment or payment at maturity, as applicable, will not reflect changes in the prices of the underlying shares other than on the observation dates and redemption determination dates, as applicable.

▪ Because the securities are linked to the worst performing (and not the average performance) of the underlying shares, 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 determination closing price or final share price of one of the underlying shares 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 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 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 Shares-related Risks

▪ The stocks held by the XLP, the XLE and the XLV are concentrated in three sectors.

▪ Adverse conditions in the consumer staples sector may reduce your return on the securities.

▪ Adverse conditions in the energy sector may reduce your return on the securities.

▪ The stocks of companies in the energy sector are subject to swift price fluctuations.

▪ Adverse conditions in the health care sector may reduce your return on the securities.

▪ The anti-dilution adjustments will be limited.

▪ The performance of each of the underlying shares may not correlate with the performance of its respective underlying index as well as the net asset value per share of such underlying shares, especially during periods of market volatility.

▪ The publisher or the sponsor or investment advisor of any of the underlying shares may adjust such underlying shares in a way that affects its values, and the publisher or the sponsor or investment advisor 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.
