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 PLUS do not guarantee the repayment of principal and do not provide for the regular payment of interest. The PLUS are for investors who seek an equity index-based return and who are willing to risk their principal and forgo current income in exchange for the leverage feature, which applies for a limited range of upside performance of the underlying index. The PLUS are our senior debt securities. Any payments on the securities are fully and unconditionally guaranteed by Bank of America Corporation (“BAC”). The PLUS are issued as part of BofA Finance LLC’s (“BofA Finance”) “Medium-Term Notes, Series A” program.

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 significant loss; there is no guaranteed return of principal.

▪The return on the PLUS will be limited to the maximum payment at maturity.

▪The PLUS do not bear interest.

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

▪The payment at maturity will not reflect changes in the level of the underlying index other than on the valuation date.

▪Any payments on the PLUS 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 PLUS.

▪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 PLUS 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 PLUS in any secondary market (if any exists) at any time.

▪We cannot assure you that a trading market for your PLUS 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 PLUS 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 publisher of the underlying index may adjust the underlying index in a way that affects its levels, and the publisher has no obligation to consider your interests.

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

Tax-related Risks

▪The U.S. federal income tax consequences of an investment in the PLUS are uncertain, and may be adverse to a holder of the PLUS.
