If the Ending Value is less than the Starting Value, you will lose some, and possibly all, of the principal amount of your Securities on the Maturity Date.

The initial estimated value of the Securities as of the Pricing Date is expected to be between $916.75 and $966.75 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 “Selected Risk Considerations” beginning on page PS-7 of the accompanying preliminary pricing supplement and “Structuring the Securities” on page PS-17 of the accompanying preliminary pricing supplement for additional information.

Selected Risk Considerations

The risks set forth below, as well as additional risks related to this investment, are discussed in detail in the “Selected Risk Considerations” 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.

●The Securities do not bear interest.

●The return on the Securities will be limited to the Maximum Return.

●The Maturity Payment Amount will not reflect the level of the Underlying other than on the Calculation Day.

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

●The Maturity Date may be postponed if the Calculation Day is postponed.

●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’s 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.

●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 Wells Fargo Securities, LLC (“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 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.

●Any payments on the Securities will depend upon the performance of the Underlying, and therefore the Securities are subject to the following risks, each as discussed in more detail in the accompanying product supplement.

oChanges that affect the Underlying may adversely affect the value of the Securities and any payments on the Securities.

oWe and our affiliates have no affiliation with the index sponsor and have not independently verified its public disclosure of information.
