•The Notes will not be listed on any securities exchange.

•CUSIP No. 09711NLU2.

The initial estimated value of the Notes as of the pricing date is expected to be between $920.00 and $970.00 per $1,000.00 in principal amount of Notes, which is less than the public offering price listed below. The actual value of your Notes at any time will reflect many factors and cannot be predicted with accuracy. See "Risk Factors" beginning on page PS-9 of this pricing supplement and "Structuring the Notes" on page PS-27 of this pricing supplement for additional information.

There are important differences between the Notes and a conventional debt security. Potential purchasers of the Notes should consider the information in "Risk Factors" beginning on page PS-9 of this pricing supplement, page PS-3 of the accompanying product supplement, "Additional Risk Factors Relating to SLB" beginning on page PS-14 of this pricing supplement and "Risk Factors beginning on page S-7 of the accompanying prospectus supplement, and page 7 of the accompanying prospectus.

None of the Securities and Exchange Commission (the "SEC"), any state securities commission, or any other regulatory body has approved or disapproved of these securities or determined if this pricing supplement and the accompanying product supplement, prospectus supplement and prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

(1)Certain dealers who purchase the Notes for sale to certain fee-based advisory accounts may forgo some or all of their selling concessions, fees or commissions. The public offering price for investors purchasing the Notes in these fee-based advisory accounts may be as low as $976.50 per $1,000.00 in principal amount of Notes.

(2)The underwriting discount per $1,000.00 in principal amount of Notes may be as high as $23.50, resulting in proceeds, before expenses, to BofA Finance of as low as $976.50 per $1,000.00 in principal amount of Notes.

* The Call Observation Dates are subject to postponement as described under "Additional Terms of the Notes-Events Relating to Observation Dates" beginning on page PS-16 of this product supplement, with references to "Observation Dates" being read as references to "Call Observation Dates."

Any payments on the Notes depend on the credit risk of BofA Finance, as Issuer, and BAC, as Guarantor, and on the performance of the Underlyings. The economic terms of the Notes are based on BAC's internal funding rate, which is the rate it would pay to borrow funds through the issuance of market-linked notes, and the economic terms of certain related hedging arrangements BAC's affiliates enter into. BAC's internal funding rate is typically lower than the rate it would pay when it issues conventional fixed or floating rate debt securities. This difference in funding rate, as well as the underwriting discount, if any, and the hedging related charges described below (see "Risk Factors" beginning on page PS-9), will reduce the economic terms of the Notes to you and the initial estimated value of the Notes. Due to these factors, the public offering price you pay to purchase the Notes will be greater than the initial estimated value of the Notes as of the pricing date.

The initial estimated value range of the Notes is set forth on the cover page of this pricing supplement. The final pricing supplement will set forth the initial estimated value of the Notes as of the pricing date. For more information about the initial estimated value and the structuring of the Notes, see "Risk Factors" beginning on page PS-9 and "Structuring the Notes" on page PS-27.

Total Contingent Coupon Payment Examples

The table below illustrates the hypothetical total Contingent Coupon Payments per $1,000.00 in principal amount of Notes over the term of the Notes, based on the Contingent Coupon Payment of $32.50, depending on how many Contingent Coupon Payments are payable prior to an Automatic Call or maturity. Depending on the performance of the Underlyings, you may not receive any Contingent Coupon Payments during the term of the Notes.

Hypothetical Payout Profile and Examples of Payments at Maturity

Contingent Income Auto-Callable Yield Notes Table

The following table is for purposes of illustration only. It assumes the Notes have not been automatically called prior to maturity and is based on hypothetical values and shows hypothetical returns on the Notes. The table illustrates the calculation of the Redemption Amount and the return on the Notes based on a hypothetical Starting Value of 100 for the Least Performing Underlying, a hypothetical Coupon Barrier of 62 for the Least Performing Underlying, a hypothetical Threshold Value of 62 for the Least Performing Underlying, the Contingent Coupon Payment of $32.50 per $1,000.00 in principal amount of Notes and a range of hypothetical Ending Values of the Least Performing Underlying. The actual amount you receive and the resulting return will depend on the actual Starting Values, Coupon Barriers, Threshold Values, Observation Values and Ending Values of the Underlyings, whether the Notes are automatically called prior to maturity, and whether you hold the Notes to maturity. The following examples do not take into account any tax consequences from investing in the Notes.

For recent actual values of the Underlyings, see "The Underlyings" section below. The Ending Value of each Underlying will not include any income generated by dividends or other distributions paid with respect to shares or units of that Underlying or on the securities or assets included in that Underlying, as applicable. In addition, all payments on the Notes are subject to Issuer and Guarantor credit risk.

Risk Factors

Your investment in the Notes entails significant risks, many of which differ from those of a conventional debt security. Your decision to purchase the Notes should be made only after carefully considering the risks of an investment in the Notes, including those discussed below, with your advisors in light of your particular circumstances. The Notes are not an appropriate investment for you if you are not knowledgeable about significant elements of the Notes or financial matters in general. You should carefully review risks set forth in "Additional Risk Factors Relating to SLB "beginning on page PS-14 of this pricing supplement as well as the more detailed explanation of risks relating to the Notes in the "Risk Factors" sections beginning on page PS-3 of the accompanying product supplement, page S-7 of the accompanying prospectus supplement and page 7 of the accompanying prospectus, each as identified on page PS-31 below.

Structure-related Risks

•Your investment may result in a loss; there is no guaranteed return of principal. There is no fixed principal repayment amount on the Notes at maturity. If the Notes are not automatically called prior to maturity and the Ending Value of either Underlying is less than its Threshold Value, at maturity, your investment will be subject to 1:1 downside exposure to decreases in the value of the Least Performing Underlying and you will lose 1% of the principal amount for each 1% that the Ending Value of the Least Performing Underlying is less than its Starting Value. In that case, you will lose a significant portion or all of your investment in the Notes.

•Your return on the Notes is limited to the return represented by the Contingent Coupon Payments, if any, over the term of the Notes. Your return on the Notes is limited to the Contingent Coupon Payments paid over the term of the Notes, regardless of the extent to which the Observation Value or Ending Value of any Underlying exceeds its Coupon Barrier or Starting Value, as applicable. Similarly, the amount payable at maturity or upon an Automatic Call will never exceed the sum of the principal amount and the applicable Contingent Coupon Payment, regardless of the extent to which the Observation Value or Ending Value of any Underlying exceeds its Starting Value. In contrast, a direct investment in an Underlying or in the securities included in one mor more of the Underlyings, as applicable, would allow you to receive the benefit of any appreciation in their values. Any return on the Notes will not reflect the return you would realize if you actually owned those securities or assets and received the dividends paid or distributions made on them.

•The Notes are subject to a potential Automatic Call, which would limit your ability to receive the Contingent Coupon Payments over the full term of the Notes. The Notes are subject to a potential Automatic Call. Beginning with the July 27, 2026 Call Observation Date, the Notes will be automatically called if, on any Call Observation Date, the Observation Value of each Underlying is greater than or equal to its Call Value. If the Notes are automatically called prior to the Maturity Date, you will be entitled to receive the Early Redemption Amount on the applicable Call Payment Date, and no further amounts will be payable on the Notes. In this case, you will lose the opportunity to continue to receive Contingent Coupon Payments after the date of the Automatic Call. If the Notes are called prior to the Maturity Date, you may be unable to invest in other securities with a similar level of risk that could provide a return that is similar to the Notes.

•You may not receive any Contingent Coupon Payments. The Notes do not provide for any regular fixed coupon payments. Investors in the Notes will not necessarily receive any Contingent Coupon Payments on the Notes. If the Observation Value of any Underlying is less than its Coupon Barrier on an Observation Date, you will not receive the Contingent Coupon Payment applicable to that Observation Date. If the Observation Value of any Underlying is less than its Coupon Barrier on all the Observation Dates during the term of the Notes, you will not receive any Contingent Coupon Payments during the term of the Notes, and will not receive a positive return on the Notes.

•Your return on the Notes may be less than the yield on a conventional debt security of comparable maturity. Any return that you receive on the Notes may be less than the return you would earn if you purchased a conventional debt security with the same Maturity Date. As a result, your investment in the Notes may not reflect the full opportunity cost to you when you consider factors, such as inflation, that affect the time value of money. In addition, if interest rates increase during the term of the Notes, the Contingent Coupon Payment (if any) may be less than the yield on a conventional debt security of comparable maturity.

•The Contingent Coupon Payment, Early Redemption Amount or Redemption Amount, as applicable, will not reflect changes in the values of the Underlyings other than on the Observation Dates or Call Observation Dates, as applicable. The values of the Underlyings during the term of the Notes other than on the Observation Dates or Call Observation Dates, as applicable, will not affect payments on the Notes. Notwithstanding the foregoing, investors should generally be aware of the performance of the Underlyings while holding the Notes, as the performance of the Underlyings may influence the market value of the Notes. The calculation agent will determine whether each Contingent Coupon Payment is payable and will calculate the Early Redemption Amount or the Redemption Amount, as applicable, by comparing only the Starting Value, the Coupon Barrier, the Call Value or the Threshold Value, as applicable, to the Observation Value or the Ending Value for each Underlying. No other values of the Underlyings will be taken into account. As a result, if the Notes are not automatically called prior to maturity and the Ending Value of the Least Performing Underlying is less than its Threshold Value, you will receive less than the principal amount at maturity even if the value of each Underlying was always above its Threshold Value prior to the Valuation Date.

•Because the Notes are linked to the least performing (and not the average performance) of the Underlyings, you may not receive any return on the Notes and may lose a significant portion or all of your investment in the Notes even if the Observation Value or Ending Value of one Underlying is greater than or equal to its Coupon Barrier or Threshold Value, as applicable. Your Notes are linked to the least performing of the Underlyings, and a change in the value of one Underlying may not correlate with changes

Contingent Income Auto-Callable Yield Notes Linked to the Least Performing of the Common Stock of SLB N.V. (SLB Limited) and the United States Oil Fund, LP

in the value of the other Underlying. The Notes are not linked to a basket composed of the Underlyings, where the depreciation in the value of one Underlying could be offset to some extent by the appreciation in the value of the other Underlying. In the case of the Notes, the individual performance of each Underlying would not be combined, and the depreciation in the value of one Underlying would not be offset by any appreciation in the value of the other Underlying. Even if the Observation Value of an Underlying is at or above its Coupon Barrier on an Observation Date, you will not receive the Contingent Coupon Payment with respect to that Observation Date if the Observation Value of the other Underlying is below its Coupon Barrier on that day. In addition, even if the Ending Value of an Underlying is at or above its Threshold Value, you will lose a significant portion or all of your investment in the Notes if the Ending Value of the Least Performing Underlying is below its Threshold Value.

•Any payments on the Notes 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 Notes. The Notes are our unsecured senior debt securities. Any payment on the Notes will be fully and unconditionally guaranteed by the Guarantor. The Notes are not guaranteed by any entity other than the Guarantor. As a result, your receipt of any payments on the Notes will be dependent upon our ability and the ability of the Guarantor to repay our respective obligations under the Notes on the applicable payment date, regardless of the performance of the Underlyings. No assurance can be given as to what our financial condition or the financial condition of the Guarantor will be at any time after the pricing date of the Notes. If we and the Guarantor become unable to meet our respective financial obligations as they become due, you may not receive the amount(s) payable under the terms of the Notes.

In addition, our credit ratings and the credit ratings of the Guarantor are assessments by ratings agencies of our respective abilities to pay our obligations. Consequently, our or the Guarantor's perceived creditworthiness and actual or anticipated decreases in our or the Guarantor's credit ratings or increases in the spread between the yield on our respective securities and the yield on U.S. Treasury securities (the "credit spread") prior to the Maturity Date may adversely affect the market value of the Notes. However, because your return on the Notes depends upon factors in addition to our ability and the ability of the Guarantor to pay our respective obligations, such as the values of the Underlyings, an improvement in our or the Guarantor's credit ratings will not reduce the other investment risks related to the Notes.

•We are a finance subsidiary and, as such, have no independent assets, operations, or revenues. We are a finance subsidiary of the Guarantor, have no operations other than those related to the issuance, administration and payment of our obligations under our debt securities that are guaranteed by the Guarantor, and are dependent upon the Guarantor and/or its other subsidiaries to meet our obligations under the Notes in the ordinary course. Therefore, our ability to make payments on the Notes may be limited.

Valuation and Market-related Risks

•The public offering price you pay for the Notes will exceed their initial estimated value. The range of initial estimated values of the Notes that is provided on the cover page of this preliminary pricing supplement, and the initial estimated value as of the pricing date that will be provided in the final pricing supplement, are each estimates only, determined as of a particular point in time by reference to our and our affiliates' pricing models. These pricing models consider certain assumptions and variables, including our credit spreads and those of the Guarantor, the Guarantor's internal funding rate, mid-market terms on hedging transactions, expectations on interest rates, dividends and volatility, price-sensitivity analysis, and the expected term of the Notes. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. If you attempt to sell the Notes prior to maturity, their market value may be lower than the price you paid for them and lower than their initial estimated value. This is due to, among other things, changes in the values of the Underlyings, changes in the Guarantor's internal funding rate, and the inclusion in the public offering price of the underwriting discount, if any, and the hedging related charges, all as further described in "Structuring the Notes" below. These factors, together with various credit, market and economic factors over the term of the Notes, are expected to reduce the price at which you may be able to sell the Notes in any secondary market and will affect the value of the Notes in complex and unpredictable ways.

•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 Notes in any secondary market (if any exists) at any time. The value of your Notes at any time after issuance will vary based on many factors that cannot be predicted with accuracy, including the performance of the Underlyings, our and BAC's creditworthiness and changes in market conditions.

•We cannot assure you that a trading market for your Notes will ever develop or be maintained. We will not list the Notes on any securities exchange. We cannot predict how the Notes will trade in any secondary market or whether that market will be liquid or illiquid.

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 Notes and their market value. We, the Guarantor or one or more of our other affiliates, including BofAS, may buy or sell shares or units of the Underlyings or the securities or assets held by or included in the Underlyings, as applicable, or futures or options contracts or exchange traded instruments on the Underlyings or those securities, or other listed or over-the-counter derivative instruments linked to the Underlyings or those securities or assets . While we, the Guarantor or one or more of our other affiliates, including BofAS, may from time to time own shares or units of the Underlyings or the securities or assets represented by the Underlyings, except to the extent that BAC's common stock may be included in the Underlyings, we, the Guarantor and our other affiliates, including BofAS, do not control any company included in the Underlyings, and have not verified any

Contingent Income Auto-Callable Yield Notes Linked to the Least Performing of the Common Stock of SLB N.V. (SLB Limited) and the United States Oil Fund, LP

disclosure made by any other company. We, the Guarantor or one or more of our other affiliates, including BofAS, may execute such purchases or sales for our own or their own accounts, for business reasons, or in connection with hedging our obligations under the Notes. These transactions may present a conflict of interest between your interest in the Notes and the interests we, the Guarantor and our other affiliates, including BofAS, may have in our or their proprietary accounts, in facilitating transactions, including block trades, for our or their other customers, and in accounts under our or their management. These transactions may adversely affect the values of the Underlyings in a manner that could be adverse to your investment in the Notes. On or before the pricing date, any purchases or sales by us, the Guarantor or our other affiliates, including BofAS or others on our or their behalf (including those for the purpose of hedging some or all of our anticipated exposure in connection with the Notes), may adversely affect the values of the Underlyings. Consequently, the values of the Underlyings may change subsequent to the pricing date, which may adversely affect the market value of the Notes.

We, the Guarantor or one or more of our other affiliates, including BofAS, also expect to engage in hedging activities that could adversely affect the values of the Underlyings on the pricing date. In addition, these hedging activities, including the unwinding of a hedge, may decrease the market value of your Notes prior to maturity, and may adversely affect the amounts to be paid on the Notes. We, the Guarantor or one or more of our other affiliates, including BofAS, may purchase or otherwise acquire a long or short position in the Notes, the Underlyings or the securities represented by the Underlyings and may hold or resell the Notes, the Underlyings or the securities represented by the Underlyings. For example, BofAS may enter into these transactions in connection with any market making activities in which it engages. We cannot assure you that these activities will not adversely affect the values of the Underlyings, the market value of your Notes prior to maturity or the amounts payable, if any, on the Notes.

•There may be potential conflicts of interest involving the calculation agent, which is an affiliate of ours. We have the right to appoint and remove the calculation agent. One of our affiliates will be the calculation agent for the Notes and, as such, will make a variety of determinations relating to the Notes, including the amounts that will be paid on the Notes. Under some circumstances, these duties could result in a conflict of interest between its status as our affiliate and its responsibilities as calculation agent.

ETF-related Risks

•The USO's underlying assets are concentrated in one sector. The USO's underlying assets will consist primarily of futures contracts for light, sweet crude oil and other petroleum based fuels that are traded on certain exchanges (collectively, "Oil Futures Contracts"). As a result, the underlying assets that will in part determine the performance of the Notes are concentrated in one sector. Although an investment in the Notes will not give holders any ownership or other direct interests in the Oil Futures Contracts, the return on an investment in the Notes will be subject to certain risks associated with a direct investment in a futures contract for oil. Accordingly, by investing in the Notes, you will not fully benefit from the diversification which could result from an investment linked to assets associated with multiple sectors.

•Legal and regulatory changes could adversely affect the return on and value of your Notes. The value of commodities or futures contracts could be adversely affected by new laws or regulations or by the reinterpretation of existing laws or regulations (including, without limitation, those related to taxes and duties on commodities and futures contracts) by one or more governments, courts, or other official bodies. Futures contracts and options on futures contracts, including those related to the USO, are subject to extensive statutes, regulations, and margin requirements. The Commodity Futures Trading Commission, commonly referred to as the "CFTC," and the exchanges on which such futures contracts trade, are authorized to take extraordinary actions in the event of a market emergency, including, for example, the retroactive implementation of speculative position limits or higher margin requirements, the establishment of daily limits and the suspension of trading. Furthermore, certain exchanges have regulations that limit the amount of fluctuations in futures contract prices that may occur during a single five-minute trading period. These limits could adversely affect the market prices of relevant futures and options contracts and forward contracts.

In the U.S., the regulation of commodity transactions is subject to ongoing modification by governmental action. For example, the CFTC has interpreted the Dodd-Frank Wall Street Reform and Consumer Protection Act ("Dodd-Frank"), which was enacted in July 2010, to require the CFTC to impose limits on the size of positions that can be held by market participants in futures contracts and over-the-counter derivatives on certain physical commodities. The CFTC adopted final position limits rules in October 2020; the final rules became effective in March 2021 and are in the process of being phased in. While the ultimate effect of the final position limit rules are not yet known, these limits will likely restrict the ability of many market participants to trade in the commodities markets to the same extent as they have in the past, including affecting their ability to enter into or maintain hedge positions in the applicable commodity or futures contracts. These rules and various other legislative and regulatory requirements may, among other things, reduce liquidity, increase market volatility, and increase costs in these markets. These consequences could adversely affect the value of the USO and the value of your Notes.

In addition, other governmental or regulatory bodies (such as the European Commission) have proposed or may propose in the future legislation or regulations containing restrictions similar to those contemplated by Dodd-Frank, or other legislation or regulations containing other restrictions that could adversely impact the liquidity of and increase costs of participating in the commodities markets. If such legislation or regulations are adopted or other legislation or regulations are adopted in the future, they could have an adverse effect on the value of the USO and your Notes.

•The price of crude oil is subject to swift price fluctuations. The USO's Underlying Asset is a futures contract for crude oil. The price of

Contingent Income Auto-Callable Yield Notes Linked to the Least Performing of the Common Stock of SLB N.V. (SLB Limited) and the United States Oil Fund, LP

crude oil is affected by supply and demand and is subject to swift fluctuations caused by events relating to international politics, energy conservation, the success of exploration projects and tax and other governmental regulatory policies. Weak demand for crude oil would adversely impact the price of the Underlying Asset, the market price of the USO, and the value of the Notes.

•Single commodity prices tend to be more volatile than, and may not correlate with, the prices of commodities generally.The Notes are linked the USO, which tracks the daily price movements of light, sweet crude oil, and not to a diverse basket of commodities or a broad-based commodity index. The prices of the Underlying may not correlate to the prices of commodities generally and may diverge significantly from the prices of commodities generally. Because the Notes are linked to an Underlying which tracks the price of a single commodity, they carry greater risk and may be more volatile than securities linked to the prices of a larger number of commodities or a broad-based commodity index. In addition, the prices of many individual commodities, including crude oil, have recently been highly volatile and there can be no assurance that the volatility will lessen.

•The Notes provide exposure to an ETF that tracks futures contracts on light, sweet crude oil and not direct exposure to such commodity. The price of a futures contract reflects the expected value of the underlying commodity upon delivery in the future, whereas the spot price of the commodity reflects the immediate delivery value of that commodity. A variety of factors can lead to a disparity between the expected future price of a commodity and its spot price at a given point in time, such as the cost of storing the commodity for the term of the futures contract, interest charges incurred to finance the purchase of the commodity and expectations concerning supply and demand for the commodity. The price movement of a futures contract is typically correlated with the movements of the spot price of the reference commodity, but the correlation is generally imperfect and price movements of the spot price may not be reflected in the futures market (and vice versa).

•Investments linked to an underlying that tracks commodities are subject to sharp fluctuations in commodity prices. Investments, such as the Notes, linked to an underlying that tracks the prices of a commodity are subject to sharp fluctuations in the prices of commodities and commodity futures over short periods of time for a variety of reasons, including changes in supply and demand relationships; weather; climatic events; the occurrence of natural disasters; wars; political and civil upheavals; acts of terrorism; trade, fiscal, monetary, and exchange control programs; domestic and foreign political and economic events and policies; disease; pestilence; technological developments; changes in interest rates; and trading activities in commodities and commodity futures. These factors may affect the commodity price and, in turn, the price of the of the Underlying and the value of the Notes in varying and potentially inconsistent ways. As a result of these or other factors, the commodity price and the price of the Underlying may be, and recently have been, highly volatile.

•The Notes will not be regulated by the CFTC. Unlike an investment in the Notes, an investment in a collective investment vehicle that invests in futures contracts on behalf of its participants may be regulated as a commodity pool and its operator may be required to be registered with and regulated by the CFTC as a "commodity pool operator" (a "CPO"). Because the Notes will not be interests in a commodity pool, the Notes will not be regulated by the CFTC as a commodity pool, neither we nor the Guarantor will be registered with the CFTC as a CPO, and you will not benefit from the CFTC's or any non-U.S. regulatory authority's regulatory protections afforded to persons who trade in futures contracts or who invest in regulated commodity pools.

•Crude oil prices can be volatile as a result of various factors that we cannot control, and this volatility may reduce the market value of the Notes. Historically, oil prices have been highly volatile. They are affected by numerous factors, including oil supply and demand, the level of global industrial activity, the driving habits of consumers, public health, political events and policies, regulations, weather, fiscal, monetary and exchange control programs, and, especially, direct government intervention such as embargoes, and supply disruptions in major producing or consuming regions such as the Middle East, the United States, Latin America, and Russia. The outcome of meetings of the Organization of Petroleum Exporting Countries also can affect liquidity and world oil supply and, consequently, the value of the USO. Market expectations about these events and speculative activity also may cause oil prices to fluctuate unpredictably. If the volatility of the underlying assets increase or decrease, the price of the USO and, in turn, the market value of the Notes may be adversely affected.

Furthermore, a significant proportion of world oil production capacity is controlled by a small number of producers. These producers have, in certain recent periods, implemented curtailments of output and trade. These efforts at supply curtailment, or the cessation of supply, could affect the value of the USO. Additionally, the development of substitute products for oil could adversely affect the value of the USO and the value of the Notes.

•The performance of the USO may not correlate with the performance of its underlying assets, including the Benchmark Oil Futures Contract, as well as the net asset value per share or unit of the USO, especially during periods of market volatility. The investment objective of the USO is for the daily changes in percentage terms of its net asset value per share to reflect the daily changes in percentage terms of the spot price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the daily changes in the price of a specified short-term futures contract on light, sweet crude oil called the "Benchmark Oil Futures Contract," plus interest earned on the USO's collateral holdings, less the USO's fees and expenses. The performance of the USO and that of its underlying assets generally will vary due to, for example, transaction costs, management fees, certain corporate actions, and timing variances. Moreover, it is also possible that the performance of the USO may not fully replicate or may, in certain circumstances, diverge significantly from the performance of its underlying assets. This could be due to, for example, differences in trading hours between the USO and the underlying assets, or due to other circumstances. This variation in performance is called the "tracking error," and, at times, the tracking error may be significant. In addition, because the shares or units of the USO are traded on a securities exchange and are subject to market supply and investor demand, the market price of one share or unit of the USO may differ from its net asset value per share or unit; shares or units of

Contingent Income Auto-Callable Yield Notes Linked to the Least Performing of the Common Stock of SLB N.V. (SLB Limited) and the United States Oil Fund, LP

the USO may trade at, above, or below its net asset value per share or unit. During periods of market volatility, market participants may be unable to calculate accurately the net asset value per share or unit of the USO and the liquidity of the USO may be adversely affected. Market volatility may also disrupt the ability of market participants to trade shares or units of the USO. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares or units of the USO. As a result, under these circumstances, the market value of shares or units of the USO may vary substantially from the net asset value per share or unit of the USO.

For the foregoing reasons, the performance of the USO may not match the performance of its underlying assets or the net asset value per share of the USO over the same period. Because of this variance, the return on the Notes to the extent dependent on the performance of the USO may not be the same as an investment directly in the underlying assets or the same as a debt security with a return directly linked to the performance of the underlying assets.

•Suspension or disruptions of market trading in the futures contracts on light, sweet crude oil may adversely affect the value of the Notes. The commodity markets are subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets, the participation of speculators and government regulation and intervention. In addition, U.S. futures exchanges and some foreign exchanges have regulations that limit the amount of fluctuation in futures contract prices that may occur during a single business day. These limits are generally referred to as "daily price fluctuation limits," and the maximum or minimum price of a contract on any given day as a result of these limits is referred to as a "limit price." Once the limit price has been reached in a particular contract, no trades may be made at a different price. Limit prices have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices. Any such distortion, disruption, or any other force majeure (such as an act of God, fire, flood, severe weather conditions, act of governmental authority, labor difficulty, etc.), may adversely affect the value of or trading in the futures contracts on light, sweet crude oil or the manner in which they are calculated, and therefore, the price of the of the USO and the value of the Notes.

•The USO may include underlying assets traded on foreign exchanges that are less regulated than U.S. markets and may involve different and greater risks than trading on U.S. exchanges. The USO may track futures contracts on light, sweet crude oil that trade on exchanges located outside the U.S. The regulations of the CFTC do not apply to trading on foreign exchanges, and trading on foreign exchanges may involve different and greater risks than trading on U.S. exchanges. Certain foreign markets may be more susceptible to disruption than U.S. exchanges due to the lack of a government-regulated clearinghouse system. Trading on foreign exchanges also involves certain other risks that are not applicable to trading on U.S. exchanges. Those risks include: (a) exchange rate risk relative to the U.S. dollar; (b) exchange controls; (c) expropriation; (d) burdensome or confiscatory taxation; and (e) moratoriums, and political or diplomatic events. It may also be more costly and difficult for participants in those markets to enforce the laws or regulations of a foreign country or exchange, and it is possible that the foreign country or exchange may not have laws or regulations which adequately protect the rights and interests of investors in the relevant contracts. These factors could reduce the value of the USO and the value of your Notes.

•The anti-dilution adjustments will be limited. The calculation agent may adjust the Price Multiplier of the USO and other terms of the Notes to reflect certain actions by the USO, as described in the section "Description of the Notes-Anti-Dilution and Discontinuance Adjustments Relating to ETFs" in the accompanying product supplement. The calculation agent will not be required to make an adjustment for every event that may affect the USO and will have broad discretion to determine whether and to what extent an adjustment is required.

•The publisher or the sponsor or investment advisor of the USO may adjust the USO in a way that affects its values, and the publisher or the sponsor or investment advisor has no obligation to consider your interests. The publisher or the sponsor or investment advisor of the USO can add, delete, or substitute the components included in the USO or make other methodological changes that could change its value. Any of these actions could adversely affect the value of your Notes.

Tax-related Risks

•The U.S. federal income tax consequences of an investment in the Notes are uncertain, and may be adverse to a holder of the Notes. No statutory, judicial, or administrative authority directly addresses the characterization of the Notes or securities similar to the Notes for U.S. federal income tax purposes. As a result, significant aspects of the U.S. federal income tax consequences of an investment in the Notes are not certain. Under the terms of the Notes, you will have agreed with us to treat the Notes as contingent income-bearing single financial contracts, as described below under "U.S. Federal Income Tax Summary-General." If the Internal Revenue Service (the "IRS") were successful in asserting an alternative characterization for the Notes, the timing and character of income, gain or loss with respect to the Notes may differ. No ruling will be requested from the IRS with respect to the Notes and no assurance can be given that the IRS will agree with the statements made in the section entitled "U.S. Federal Income Tax Summary." You are urged to consult with your own tax advisor regarding all aspects of the U.S. federal income tax consequences of investing in the Notes.

Additional Risk Factors Relating to SLB

•Our offering of the Notes does not constitute a recommendation of SLB. You should not take our offering of the Notes as an expression of our views about how SLB will perform in the future or as a recommendation to invest in SLB, including through an investment in the Notes. As we are part of a global financial institution, we, the Guarantor and our other affiliates may, and often do, have positions (both long and short) in SLB that may conflict with an investment in the Notes. You should undertake an independent determination of whether an investment in the Notes is suitable for you in light of your specific investment objectives, risk tolerance and financial resources.

•Our affiliates may publish research, express opinions or provide recommendations that are inconsistent with investing in SLB and any such research, opinions or recommendations could adversely affect the price of SLB. In the ordinary course of business, our affiliates may have published research reports, expressed opinions or provided recommendations on the issuer of SLB (the "Underlying Company"), SLB, the applicable financial markets or other matters that may influence the price of SLB and the value of the Notes, and may do so in the future. These research reports, opinions or recommendations may be communicated to our clients and clients of our affiliates and may be inconsistent with purchasing or holding the Notes. Any research reports, opinions or recommendations expressed by our affiliates may not be consistent with each other and may be modified from time to time without notice. Moreover, other professionals who deal in markets relating to SLB may at any time have significantly different views from those of our affiliates. For these reasons, you are encouraged to derive information concerning SLB from multiple sources, and you should not rely on the views expressed by our affiliates.

•You will have no rights as a security holder of the Underlying Company, you will have no rights to receive any shares of SLB, and you will not be entitled to dividends or other distributions by the Underlying Company. The Notes are our debt securities. They are not equity instruments, shares of stock, or securities of any other issuer, other than the related guarantees, which are the securities of the Guarantor. Investing in the Notes will not make you a holder of SLB. You will not have any voting rights, any rights to receive dividends or other distributions, or any other rights with respect to SLB. Unless otherwise set forth under the limited circumstances relating to the Price Multiplier (as described in "Additional Terms of the Notes - Anti-Dilution Adjustments for the Underlying Stock" below), the payment(s) on the Notes will not reflect the value of dividends paid or distributions made on SLB or any other rights associated with those equity securities. As a result, the return on your Notes may not reflect the return you would realize if you actually owned shares of SLB and received the dividends paid or other distributions made in connection with those shares. Your Notes will be paid in cash and you have no right to receive delivery of shares of SLB.

•The business activities of us, the Guarantor and any of our other affiliates, including the Selling Agent, relating to the Underlying Company may create conflicts of interest with you. We, the Guarantor and/or our other affiliates, including the Selling Agent, at the time of any offering of the Notes or in the future, may engage in business with the Underlying Company, including making loans to, equity investments in, or providing investment banking, asset management, or other services to the Underlying Company, its affiliates, and its competitors.

In connection with these activities, we, the Guarantor or our other affiliates, including the Selling Agent, may receive information about the Underlying Company that we or they will not divulge to you or other third parties. One or more of our affiliates may have published, and in the future may publish, research reports on the Underlying Company. This research is modified from time to time without notice and may express opinions or provide recommendations that are inconsistent with purchasing or holding your Notes. Any of these activities may adversely affect the value of SLB and, consequently, the market value of your Notes. We, the Guarantor and our other affiliates, including the Selling Agent, do not make any representation to any purchasers of the Notes regarding any matters whatsoever relating to SLB or the Underlying Company. Any prospective purchaser of the Notes should undertake an independent investigation into SLB and the Underlying Company to a level that, in its judgment, is appropriate to make an informed decision regarding an investment in the Notes. The selection of SLB does not reflect any investment recommendations from us, the Guarantor or our other affiliates, including the Selling Agent.

•The Underlying Company will have no obligations relating to the Notes. The Underlying Company will not have any financial or legal obligation with respect to the Notes or the amounts to be paid to you, including any obligation to take our interest or the interests of the noteholders into consideration for any reason, including when taking any corporate actions that might adversely affect the value of SLB or the value of the Notes. The Underlying Company will not receive any of the proceeds from any offering of the Notes, and will not be responsible for, or participate in, the offering of the Notes, or the determination or calculation of any payment(s) on the Notes.

•The Price Multiplier of SLB or other terms of the Notes will not be adjusted for all corporate events that could affect SLB or the Underlying Company. The Price Multiplier of SLB, the determination of the payment(s) on the Notes, and other terms of the Notes may be adjusted for the specified corporate events affecting SLB, as described below in the section entitled "Additional Terms of the Notes-Anti-Dilution Adjustments for the Underlying Stock." However, these adjustments do not cover all corporate events that could affect the market price of SLB, such as offerings of common shares for cash or in connection with certain acquisition transactions. The occurrence of any event that does not require the calculation agent to adjust the Price Multiplier of SLB or other terms of the Notes may adversely affect the Closing Market Price of SLB, and, as a result, the market value of the Notes.

•We, the Guarantor and our other affiliates, including the Selling Agent, do not control the Underlying Company. We, the Guarantor or our other affiliates, including the Selling Agent, currently, or in the future, may engage in business with the Underlying Company, and we, the Guarantor or our other affiliates, including the Selling Agent, may from time to time own securities of the Underlying Company. However, none of us, the Guarantor or any of our other affiliates, including the Selling Agent, have the ability to

Contingent Income Auto-Callable Yield Notes Linked to the Least Performing of the Common Stock of SLB N.V. (SLB Limited) and the United States Oil Fund, LP

control the actions of the Underlying Company, including actions that could affect the value of SLB.

•We cannot assure you that publicly available information provided about SLB or the Underlying Company is accurate or complete, and none of us, the Guarantor nor any of our other affiliates, including the Selling Agent, will perform any due diligence procedures with respect to the Underlying Company. All disclosures relating to SLB or the Underlying Companies have been derived from publicly available documents and other publicly available information, without independent verification. None of us, the Guarantor, the Selling Agent or our other affiliates has participated in, or will participate in, the preparation of those documents or make any due diligence inquiry with respect to SLB or the Underlying Company in connection with the offering of the Notes. We and the Guarantor do not make any representation that those publicly available documents or any other publicly available information regarding SLB or the Underlying Company is accurate or complete. We and the Guarantor are not responsible for the public disclosure of information by or about SLB or the Underlying Company, whether contained in filings with the SEC or otherwise made publicly available. As a result we cannot give any assurance that, prior to the date of this pricing supplement, all events which could impact SLB, the Underlying Company or the accuracy or completeness of those public documents or information have been publicly disclosed. Any subsequent disclosure or future failure to disclose material events concerning SLB or the Underlying Company could affect the value of SLB and therefore, the value of the Notes. You must rely on your own evaluation of the merits of an investment linked to SLB.

•The historical performance of SLB should not be taken as an indication of its performance during the term of the Notes. SLB may perform better or worse during the term of the Notes than it has historically. The historical performance of SLB, including any historical performance set forth in this pricing supplement, should not be taken as an indication of its future performance.

Additional Terms of the Notes

The following shall supersede and replace the section entitled "Description of the Notes- Certain Terms of the Notes- Events Relating to Observation Dates" in the accompanying product supplement:

Events Relating to Observation Dates

If, for any Underlying, (i) a Market Disruption Event occurs on a scheduled Observation Date or (ii) the Calculation Agent determines that, by reason of an extraordinary event, occurrence, declaration or otherwise, any scheduled Observation Date is not a Trading Day for any Underlying (any such day in either (i) or (ii) being a "Non-Observation Date"), the Calculation Agent will determine the Closing Market Price of the Underlying for that day as follows:

•The Closing Market Price of an Underlying that is not so affected will be its Closing Market Price on that Non-Observation Date.

•The Closing Market Price of an Underlying that is affected by that Non-Observation Date will be deemed to be its Closing Market Price on the first Trading Day following that Non-Observation Date on which no Market Disruption Event occurs with respect to that Underlying; provided that the Closing Market Price will be determined (or, if not determinable, estimated) by the Calculation Agent in a manner which the Calculation Agent considers commercially reasonable under the circumstances on a date no later than the second scheduled Trading Day following that Non-Observation Date, regardless of the occurrence of a Market Disruption Event or non-Trading Day on that day.

The applicable Observation Date will be deemed to occur after the Calculation Agent has determined the Closing Market Prices of the applicable Underlyings as provided above.

With respect to SLB only (for purposes of this section, the "Underlying Stock"), the following information supersedes and supplements any contrary information included in the accompanying product supplement, prospectus supplement and prospectus.

Certain Terms of the Notes

Trading Days. As to the Underlying Stock, a Trading Day means a day on which trading is generally conducted (or was scheduled to have been generally conducted, but for the occurrence of a Market Disruption Event) on the NYSE, the Nasdaq Stock Market, the Chicago Board Options Exchange, and in the over-the-counter market for equity securities in the United States, or any successor exchange or market, or in the case of a security traded on one or more non-U.S. securities exchanges or markets, on the principal non-U.S. securities exchange or market for such security.

Closing Market Price for the Underlying Stock

The price of the Underlying Stock on any applicable Observation Date or calculation day will be determined by multiplying its respective Closing Market Price on that day by its "Price Multiplier". The initial Price Multiplier for the Underlying Stock will be 1, and will be subject to adjustment as provided below in "-Anti-Dilution Adjustments for the Underlying Stock".

The "Closing Market Price" for one share of the Underlying Stock (or one unit of any other security for which a Closing Market Price must be determined) on any Trading Day means any of the following:

•if the Underlying Stock (or such other security) is listed or admitted to trading on a national securities exchange, the last reported sale price, regular way (or, in the case of The Nasdaq Stock Market, the official closing price), of the principal trading session on that day on the principal U.S. securities exchange registered under the Securities Exchange Act of 1934, as amended (the "Exchange Act") on which the Underlying Stock (or such other security) is listed or admitted to trading;

•if the Underlying Stock (or such other security) is not listed or admitted to trading on any national securities exchange but is included in the OTC Bulletin Board Service (or any successor service) operated by FINRA (the "OTC Bulletin Board"), the last reported sale price of the principal trading session on the OTC Bulletin Board on that day;

•if the Underlying Stock (or such other security) is issued by a foreign issuer and its closing price cannot be determined as set forth in the two bullet points above, and the Underlying Stock (or such other security) is listed or admitted to trading on a non-U.S. securities exchange or market, the last reported sale price, regular way, of the principal trading session on that day on the primary non-U.S. securities exchange or market on which the Underlying Stock (or such other security) is listed or admitted to trading (converted to U.S. dollars using such exchange rate as the calculation agent, in its sole discretion, determines to be commercially reasonable); or

•if the Closing Market Price cannot be determined as set forth in the prior bullets, the mean, as determined by the calculation agent, of the bid prices for the Underlying Stock (or such other security) obtained from as many dealers in that security (which may include us, BofAS and/or any of our other affiliates), but not exceeding three, as will make the bid prices available to the calculation agent. If no such bid price can be obtained, the Closing Market Price will be determined (or, if not determinable, estimated) by the calculation agent in its sole discretion in a commercially reasonable manner.

Contingent Income Auto-Callable Yield Notes Linked to the Least Performing of the Common Stock of SLB N.V. (SLB Limited) and the United States Oil Fund, LP

Market Disruption Events for the Underlying Stock

As to the Underlying Stock, a "Market Disruption Event" means one or more of the following events, as determined by the calculation agent in its sole discretion:

(A)the suspension, absence or material limitation of trading, in each case, for more than two consecutive hours of trading, or during the one-half hour period preceding the close of trading, of the shares of the Underlying Stock (or shares of any Successor Entity, as defined below in " -Anti-Dilution Adjustments-Reorganization Events") on the primary exchange where such shares trade, as determined by the calculation agent (without taking into account any extended or after-hours trading session); or

(B)the suspension, absence or material limitation of trading, in each case, for more than two consecutive hours of trading, or during the one-half hour period preceding the close of trading, on the primary exchange that trades options contracts or futures contracts related to the shares of the Underlying Stock (or shares of any Successor Entity), as determined by the calculation agent (without taking into account any extended or after-hours trading session), in options contracts or futures contracts related to the shares of the Underlying Stock (or shares of any Successor Entity).

For the purpose of determining whether a Market Disruption Event has occurred:

(1)a limitation on the hours in a Trading Day and/or number of days of trading will not constitute a Market Disruption Event if it results from an announced change in the regular business hours of the relevant exchange;

(2)a decision to permanently discontinue trading in the shares of the Underlying Stock (or shares of any Successor Entity) or the relevant futures or options contracts relating to such shares will not constitute a Market Disruption Event;

(3)a suspension in trading in a futures or options contract on the shares of the Underlying Stock (or shares of any Successor Entity), by a major securities market by reason of (a) a price change violating limits set by that securities market, (b) an imbalance of orders relating to those contracts, or (c) a disparity in bid and ask quotes relating to those contracts, will each constitute a suspension of or material limitation on trading in futures or options contracts relating to the Underlying Stock;

(4)subject to paragraph (3) above, a suspension of or material limitation on trading on the relevant exchange will not include any time when that exchange is closed for trading under ordinary circumstances; and

(5)for the purpose of clause (A) above, any limitations on trading during significant market fluctuations under NYSE Rule 80B, or any applicable rule or regulation enacted or promulgated by the NYSE or any other self-regulatory organization or the SEC of similar scope as determined by the calculation agent, will be considered "material."

Anti-Dilution Adjustments for the Underlying Stock

As to the Underlying Stock, the calculation agent, in its sole discretion, may adjust its Price Multiplier, and any other terms of the Notes, if an event described below occurs after the pricing date and on or before the maturity date of the Notes and if the calculation agent determines that such an event has a dilutive or concentrative effect on the theoretical value of the shares of the Underlying Stock or shares of any Successor Entity.

The Price Multiplier for the Underlying Stock resulting from any of the adjustments specified below will be rounded to the eighth decimal place with five one-billionths being rounded upward. No adjustments to the Price Multiplier will be required unless the adjustment would require a change of at least 0.1% in the Price Multiplier then in effect. Any adjustment that would require a change of less than 0.1% in the Price Multiplier which is not applied at the time of the event may be reflected at the time of any subsequent adjustment that would require a change of the Price Multiplier. The required adjustments specified below do not cover all events that could affect the Underlying Stock.

No adjustments to the Price Multiplier for the Underlying Stock or any other terms of the Notes will be required other than those specified below. However, the calculation agent may, at its sole discretion, make additional adjustments to the Price Multiplier or any other terms of the Notes to reflect changes to the Underlying Stock if the calculation agent determines that the adjustment is appropriate to ensure an equitable result.

The calculation agent will be solely responsible for the determination of any adjustments to the Price Multiplier for the Underlying Stock or any other terms of the Notes and of any related determinations with respect to any distributions of stock, other securities or other property or assets, including cash, in connection with any corporate event described below; its determinations and calculations will be conclusive absent a determination of a manifest error.

No adjustments are required to be made for certain other events, such as offerings of common equity securities by an Underlying Company for cash or in connection with the occurrence of a partial tender or exchange offer for the applicable Underlying Stock by an Underlying Company.

Following an event that results in an adjustment to the Price Multiplier for the Underlying Stock or any of the other terms of the Notes, the calculation agent may (but is not required to) provide holders of the Notes with information about that adjustment as it deems appropriate, depending on the nature

Contingent Income Auto-Callable Yield Notes Linked to the Least Performing of the Common Stock of SLB N.V. (SLB Limited) and the United States Oil Fund, LP

of the adjustment. Upon written request by any holder of the Notes, the calculation agent will provide that holder with information about such adjustment.

The calculation agent, in its sole discretion and as it deems reasonable, may adjust the Price Multiplier for the Underlying Stock and any other terms of the Notes as a result of certain events related to the Underlying Stock, which include, but are not limited to, the following:

Stock Splits and Reverse Stock Splits. If the Underlying Stock is subject to a stock split or reverse stock split, then once such split has become effective, the Price Multiplier for the Underlying Stock will be adjusted such that the new Price Multiplier will equal the product of:

•the prior Price Multiplier; and

•the number of shares that a holder of one share of the Underlying Stock before the effective date of the stock split or reverse stock split would have owned immediately following the applicable effective date.

For example, a two-for-one stock split would ordinarily change a Price Multiplier of one into a Price Multiplier of two. In contrast, a one-for-two reverse stock split would ordinarily change a Price Multiplier of one into a Price Multiplier of one-half.

Stock Dividends. If the Underlying Stock is subject to (i) a stock dividend (i.e., an issuance of additional shares of the Underlying Stock) that is given ratably to all holders of the Underlying Stock or (ii) a distribution of additional shares of the Underlying Stock as a result of the triggering of any provision of the organizational documents of the applicable Underlying Company, then, once the dividend or distribution has become effective and the Underlying Stock is trading ex-dividend, the Price Multiplier for the Underlying Stock will be adjusted on the ex-dividend date such that the new Price Multiplier will equal the prior Price Multiplier plus the product of:

•the prior Price Multiplier; and

•the number of additional shares issued in the stock dividend with respect to one share of the Underlying Stock;

•provided that no adjustment will be made for a stock dividend or distribution for which the number of shares of the Underlying Stock paid or distributed is based on a fixed cash equivalent value, unless such distribution is an Extraordinary Dividend (as defined below).

For example, a stock dividend of one new share for each share held would ordinarily change a Price Multiplier of one into a Price multiplier of two.

Extraordinary Dividends. There will be no adjustments to the Price Multiplier for the Underlying Stock to reflect any cash dividends or cash distributions paid with respect to SLB other than Extraordinary Dividends, as described below, and distributions described in "-Reorganization Events" below.

An "Extraordinary Dividend" means, with respect to a cash dividend or other distribution with respect to the Underlying Stock, a dividend or other distribution that the calculation agent determines, in its sole discretion, is not declared or otherwise made according to the Underlying Company's then existing policy or practice of paying such dividends on a quarterly or other regular basis. If an Extraordinary Dividend occurs, the Price Multiplier will be adjusted on the ex-dividend date so that the new Price Multiplier will equal the product of:

•the prior Price Multiplier; and

•a fraction, the numerator of which is the Closing Market Price per share of the Underlying Stock on the Trading Day preceding the ex-dividend date and the denominator of which is the amount by which the Closing Market Price per share of the Underlying Stock on that preceding Trading Day exceeds the Extraordinary Dividend Amount.

The "Extraordinary Dividend Amount" with respect to an Extraordinary Dividend will equal:

•in the case of cash dividends or other distributions that constitute regular dividends, the amount per share of the Underlying Stock of that Extraordinary Dividend minus the amount per share of the immediately preceding non-Extraordinary Dividend for that share; or

•in the case of cash dividends or other distributions that do not constitute regular dividends, the amount per share of the Underlying Stock of that Extraordinary Dividend.

To the extent an Extraordinary Dividend is not paid in cash, the value of the non-cash component will be determined by the calculation agent, whose determination will be conclusive. A distribution on the Underlying Stock described in the section " -Issuance of Transferable Rights or Warrants" below or in clause (a), (d) or (e) of the section entitled " -Anti-Dilution Adjustments-Reorganization Events" below that also constitutes an Extraordinary Dividend will only cause an adjustment under those respective sections.

Issuance of Transferable Rights or Warrants. If an Underlying Company issues transferable rights or warrants to all holders of record of the Underlying Stock to subscribe for or purchase the Underlying Stock, including new or existing rights to purchase the Underlying Stock under a shareholder rights plan or arrangement, then the Price Multiplier will be adjusted on the Trading Day immediately following the issuance of those transferable rights or warrants so that the new Price Multiplier will equal the prior Price Multiplier plus the product of:

Contingent Income Auto-Callable Yield Notes Linked to the Least Performing of the Common Stock of SLB N.V. (SLB Limited) and the United States Oil Fund, LP

•the prior Price Multiplier; and

•the number of shares of the Underlying Stock that can be purchased with the cash value of those warrants or rights distributed on one share of the Underlying Stock.

The number of shares that can be purchased will be based on the Closing Market Price of the Underlying Stock on the date the new Price Multiplier is determined. The cash value of those warrants or rights, if the warrants or rights are traded on a registered national securities exchange, will equal the closing price of that warrant or right. If the warrants or rights are not traded on a registered national securities exchange, the cash value will be determined by the calculation agent and will equal the average of the bid prices obtained from three dealers at 3:00 p.m., New York time, on the date the new Price Multiplier is determined, provided that if only two of those bid prices are available, then the cash value of those warrants or rights will equal the average of those bids and if only one of those bids is available, then the cash value of those warrants or rights will equal that bid.

Reorganization Events

If after the pricing date and on or prior to the later of the Valuation Date or applicable Observation Date, as to the Underlying Stock:

(a)there occurs any reclassification or change of the Underlying Stock, including, without limitation, as a result of the issuance of tracking stock by the Underlying Company;

(b)the Underlying Company, or any surviving entity or subsequent surviving entity of the Underlying Company (a "Successor Entity"), has been subject to a merger, combination, or consolidation and is not the surviving entity;

(c)any statutory exchange of securities of the Underlying Company or any Successor Entity with another corporation occurs, other than under clause (b) above;

(d)the Underlying Company is liquidated or is subject to a proceeding under any applicable bankruptcy, insolvency, or other similar law;

(e)the Underlying Company issues to all of its shareholders securities of an issuer other than the Underlying Company, including equity securities of an affiliate of the Underlying Company, other than in a transaction described in clauses (b), (c), or (d) above;

(f)a tender or exchange offer or going-private transaction is consummated for all the outstanding shares of the Underlying Company;

(g)there occurs any reclassification or change of the Underlying Stock that results in a transfer or an irrevocable commitment to transfer all such outstanding shares of the Underlying Stock to another entity or person;

(h)the Underlying Company or any Successor Entity is the surviving entity of a merger, combination, or consolidation, that results in the outstanding shares of the Underlying Stock (other than shares of the Underlying Stock owned or controlled by the other party to such transaction) immediately prior to such event collectively representing less than 50% of the outstanding shares of the Underlying Stock immediately following such event; or

(i)the Underlying Company ceases to file the financial and other information with the SEC in accordance with Section 13(a) of the Exchange Act (an event in clauses (a) through (i), a "Reorganization Event"),

then, on or after the effective date of the Reorganization Event, the calculation agent shall, in its sole discretion, make an adjustment to the Price Multiplier for the Underlying Stock or any other terms of the Notes as the calculation agent, in its sole discretion, determines appropriate to account for the economic effect on the Notes of that Reorganization Event (including adjustments to account for changes in volatility, expected dividends, stock loan rate, or liquidity relevant to the Underlying Stock or to the Notes), which may, but need not, be determined by reference to the adjustment(s) made in respect of such Reorganization Event by an options exchange to options on the Underlying Stock traded on that options exchange, and determine the effective date of that adjustment. For the avoidance of doubt, any adjustment will be made on or after the effective date of the Reorganization Event and not on the date of the announcement of a plan or intention to effect such an event.

If the calculation agent determines that no adjustment that it could make will produce a commercially reasonable result, then the calculation agent may cause the maturity date of the Notes to be accelerated to the fifth business day following the date of that determination and the amount payable to you will be calculated as though the date of early repayment were the stated maturity date of the Notes and as though the Valuation Date were the fifth Trading Day prior to the date of acceleration.

If an Underlying Company ceases to file the financial and other information with the SEC in accordance with Section 13(a) of the Exchange Act, as contemplated by clause (i) above, and the calculation agent determines in its sole discretion that sufficiently similar information is not otherwise available to you, then the calculation agent may cause the maturity date of the Notes to be accelerated to the fifth business day following the date of that determination and the amount payable to you will be calculated as though the date of early repayment were the stated maturity date of the Notes, and as though the Valuation Date were the fifth Trading Day prior to the date of acceleration. If the calculation agent determines that sufficiently similar information is available to you, the Reorganization Event will be deemed to have not occurred.

Alternative Anti-Dilution and Reorganization Adjustments

The calculation agent may elect at its discretion to not make any of the adjustments to the Price Multiplier for the Underlying Stock or to the other terms of the Notes described in this section, but may instead make adjustments, in its discretion, to the Price Multiplier or any other terms of the Notes that will reflect the adjustments to the extent practicable made by the Options Clearing Corporation on options contracts on the Underlying Stock or any successor common stock. For example, if the Underlying Stock is subject to a two-for-one stock split, and the Options Clearing Corporation adjusts the strike prices of the options contract on the Underlying Stock by dividing the strike price by two, then the calculation agent may also elect to divide any applicable "starting value" of the Underlying Stock by two. In this case, the Price Multiplier will remain one. This adjustment would have the same economic effect on holders of the Notes as if the Price Multiplier had been adjusted.

All disclosures contained in this pricing supplement regarding the USO, including, without limitation, its make-up, method of calculation, and changes in its components, have been derived from publicly available sources. The information reflects the policies of, and is subject to change by, the sponsor of the USO (the "Underlying Sponsor"). The Underlying Sponsor, which licenses the copyright and all other rights to the USO, has no obligation to continue to publish, and may discontinue publication of, the USO. The consequences of the Underlying Sponsor discontinuing publication of the USO are discussed in "Description of the Notes - Discontinuance of or Material Change to an ETF" in the accompanying product supplement. None of us, the Guarantor, the calculation agent, or BofAS accepts any responsibility for the calculation, maintenance or publication of the USO or any successor ETF.

The United States Oil Fund, LP ("USO") is an exchange traded fund and commodity pool designed to track the daily price movements of light, sweet crude oil. The USO continuously issues common shares of beneficial interest ("Shares") that may be purchased and sold on the NYSE Arca stock exchange ("NYSE Arca"). The USO is managed and controlled by United States Commodity Funds LLC ("USCF"), its general partner. USCF is a single member limited liability company formed in Delaware on May 10, 2005, that is registered as a commodity pool operator with the Commodity Futures Trading Commission and is a member of the National Futures Association. The United States Oil Fund, LP trades on the NYSE Arca under the ticker symbol "USO".

Information provided to or filed with the SEC by the USO pursuant to the Securities Act of 1933 and the Securities Exchange Act of 1934 can be located by reference to SEC file numbers 333-272617 and 001-32834, respectively, through the SEC's website at http://www.sec.gov. The USO is not a mutual fund or any other type of investment company within the meaning of the Investment Company Act of 1940, as amended, and is not subject to regulation thereunder. For additional information regarding the USO and USCF, please see the United States Oil Fund, LP's prospectus. In addition, information about the USO may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents, and we have not participated in the preparation of, or verified, such publicly available information.

Investment Objective

The investment objective of the USO is for the daily changes, in percentage terms, of the net asset value ("NAV") per Share to reflect the daily changes, in percentage terms, of the spot price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the daily changes in the price of a specified short-term futures contract on light, sweet crude oil called the "Benchmark Oil Futures Contract," plus interest earned on the USO's collateral holdings, less the USO's fees and expenses. The Benchmark Oil Futures Contract is the futures contract on light, sweet crude oil delivered to Cushing, Oklahoma as traded on the New York Mercantile Exchange (the "NYMEX") that is the near month contract to expire and changes, over a ten-day period, into the NYMEX futures contract that is the next month to expire. The change from the near month contract to the next month contract occurs at the beginning of each month and will be approximately proportional, relative to total net assets, over each day of the ten-day roll period.

The USO seeks to achieve its investment objective by investing so that the average daily percentage change in the NAV, for any period of 30 successive valuation days, will be within plus/minus ten percent (10%) of the average daily percentage change in the price of the Benchmark Oil Futures Contract over the same period. As a result, investors should be aware that the USO would meet its investment objective even if there are significant deviations between changes in its daily NAV and changes in the daily price of the Benchmark Oil Futures Contract, provided that the average daily percentage change in the NAV over 30 successive valuation days is within plus/minus ten percent (10%) of the average daily percentage change in the price of the Benchmark Oil Futures Contract over the same period.

The USO invests primarily in futures contracts for light, sweet crude oil, other types of crude oil, diesel-heating oil, gasoline, natural gas, and other petroleum-based fuels that are traded on the NYMEX, ICE Futures Europe and ICE Futures U.S. or other U.S. and foreign exchanges (collectively, "Oil Futures Contracts") and to a lesser extent, in order to comply with regulatory requirements, risk mitigation measures, liquidity requirements or in view of market conditions, other oil-related investments such as cash-settled options on Oil Futures Contracts, forward contracts for oil, cleared swap contracts and non-exchange traded ("over-the-counter" or "OTC") transactions that are based on the price of oil and other petroleum-based fuels, Oil Futures Contracts and indices based on the foregoing (collectively, "Other Oil-Related Investments"). Market conditions which could cause USO to invest in Other Oil-Related Investments include those allowing USO to obtain greater liquidity or to execute transactions with more favorable pricing.

Historically, the USO has achieved its investment objective primarily by investing in the Benchmark Oil Futures Contract and in oil futures contracts for light, sweet crude oil traded on NYMEX and ICE Futures with the same maturity month as the Benchmark Oil Futures Contract. However, in April 2020, the USO announced its intent to invest in Oil Futures Contracts other than the Benchmark Oil Futures Contract and that it could, if it determined it appropriate in light of market conditions and regulatory requirements, invest in Other Oil-Related Interests.Beginning with the monthly roll in September 2023 and ending with the monthly roll in January 2024, the USO transitioned its investment portfolio and now primarily invests in Benchmark Oil Futures Contracts, consistent with the USO's investment strategy prior to April 2020. However, the USO has had, and will continue to have, the ability to invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract and Other Oil-Related Investments, such as OTC swaps, and the USO may make such investments if market conditions, regulatory requirements, risk mitigation measures (including those that may be taken by the USO, the USO's futures commission merchants, counterparties or other market participants), liquidity requirements, or other factors require the USO to do so in order to meet its investment objective. The USO may invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract, and/or Other Oil-Related Investments, as a result or in response to any of the foregoing factors. In addition, the USO may need to hold significant portions of its portfolio in cash beyond what it has historically held for reasons including (but not limited to) the need to address the changes in market conditions, regulatory requirements or risk mitigation measures or the need to satisfy potential margin requirements.

Creation and Redemption

The USO creates and redeems the Shares of the USO from time to time, but only in one or more Creation Baskets (each a block of 100,000 Shares used by the USO to issue the Shares of the USO) or Redemption Baskets (each a block of 100,000 Shares used by the USO to redeem the Shares of the USO) (each Creation Basket or Redemption Basket, a "Basket"). The creation and redemption of Baskets are only made in exchange for delivery to the USO or the distribution by the USO of the amount of obligations of the U.S. government with remaining maturities of 2 years or less ("Treasuries") and any cash represented by the Baskets being created or redeemed, the amount of which is based on the combined NAV of the number of Shares included in the Baskets being created or redeemed determined as of 4:00 p.m. Eastern time on the day the order to create or redeem Baskets is properly received.

"Authorized Participants" are the only persons that may place orders to create and redeem Baskets. Authorized Participants must be (1) registered broker-dealers or other securities market participants, such as banks and other financial institutions, that are not required to register as broker-dealers to engage in securities transactions as described below, and (2) DTC Participants.

Valuation of Shares; Computation of NAV

The Shares trade on the NYSE Arca after they are initially purchased by Authorized Participants, institutional firms that purchase Shares in blocks of Baskets through the USO's marketing agent, ALPS Distributors, Inc. (the "Marketing Agent"). The price of a Basket is equal to the NAV of 100,000 Shares on the day that the order to purchase the Basket is accepted by the Marketing Agent. The NAV per Share is calculated by taking the current market value of the USO's total assets (after close of NYSE Arca) subtracting any liabilities and dividing that total by the total number of outstanding Shares.

The offering of the USO's Shares is a "best efforts" offering, which means that neither the Marketing Agent nor any Authorized Participant is required to purchase a specific number or dollar amount of Shares. USCF pays the Marketing Agent a marketing fee consisting of a fixed annual amount plus an incentive fee based on the amount of Shares sold. Aggregate compensation paid to the Marketing Agent and any affiliate of USCF for distribution-related services in connection with this offering of Shares will not exceed ten percent (10%) of the gross proceeds of the offering.

Termination Events

The USO will dissolve at any time upon the happening of any of the following events:

•The bankruptcy, dissolution, withdrawal, or removal of USCF, unless a majority in interest of the limited partners within 90 days after such event elects to continue the USO and appoints a successor general partner; or

•The affirmative vote of a majority in interest of the limited partners, provided that prior to or concurrently with such vote, there shall have been established procedures for the assumption of the USO's obligations arising under any agreement to which the USO is a party and which is still in force immediately prior to such vote regarding termination, and there shall have been an irrevocable appointment of an agent who shall be empowered to give and receive notices, reports and payments under such agreements, and hold and exercise such other powers as are necessary to permit all other parties to such agreements to deal with such agent as if the agent were the sole owner of the USO's interest, which procedures are agreed to in writing by each of the other parties to such agreements.

Supplement to the Plan of Distribution; Role of BofAS and Conflicts of Interest

BofAS, a broker-dealer affiliate of ours, is a member of the Financial Industry Regulatory Authority, Inc. ("FINRA") and will participate as selling agent in the distribution of the Notes. Accordingly, the offering of the Notes will conform to the requirements of FINRA Rule 5121. BofAS may not make sales in this offering to any of its discretionary accounts without the prior written approval of the account holder.

We expect to deliver the Notes against payment therefor in New York, New York on a date that is greater than one business day following the pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, if the initial settlement of the Notes occurs more than one business day from the pricing date, purchasers who wish to trade the Notes more than one business day prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

Under our distribution agreement with BofAS, BofAS will purchase the Notes from us as principal at the public offering price indicated on the cover of this pricing supplement, less the indicated underwriting discount, if any. BofAS will sell the Notes to other broker-dealers that will participate in the offering and that are not affiliated with us, at an agreed discount to the principal amount. Each of those broker-dealers may sell the Notes to one or more additional broker-dealers. BofAS has informed us that these discounts may vary from dealer to dealer and that not all dealers will purchase or repurchase the Notes at the same discount. Certain dealers who purchase the Notes for sale to certain fee-based advisory accounts may forgo some or all of their selling concessions, fees or commissions. The public offering price for investors purchasing the Notes in these fee-based advisory accounts may be as low as $976.50 per $1,000.00 in principal amount of Notes.

BofAS and any of our other broker-dealer affiliates may use this pricing supplement and the accompanying product supplement, prospectus supplement and prospectus for offers and sales in secondary market transactions and market-making transactions in the Notes. However, they are not obligated to engage in such secondary market transactions and/or market-making transactions. These broker-dealer affiliates may act as principal or agent in these transactions, and any such sales will be made at prices related to prevailing market conditions at the time of the sale.

At BofAS's discretion, for a short, undetermined initial period after the issuance of the Notes, BofAS may offer to buy the Notes in the secondary market at a price that may exceed the initial estimated value of the Notes. Any price offered by BofAS for the Notes will be based on then-prevailing market conditions and other considerations, including the performance of the Underlyings and the remaining term of the Notes. However, none of us, the Guarantor, BofAS or any of our other affiliates is obligated to purchase your Notes at any price or at any time, and we cannot assure you that any party will purchase your Notes at a price that equals or exceeds the initial estimated value of the Notes.

Any price that BofAS may pay to repurchase the Notes will depend upon then prevailing market conditions, the creditworthiness of us and the Guarantor, and transaction costs. At certain times, this price may be higher than or lower than the initial estimated value of the Notes.

European Economic Area and United Kingdom

None of this pricing supplement, the accompanying product supplement, the accompanying prospectus or the accompanying prospectus supplement is a prospectus for the purposes of the Prospectus Regulation (as defined below). This pricing supplement, the accompanying product supplement, the accompanying prospectus and the accompanying prospectus supplement have been prepared on the basis that any offer of Notes in any Member State of the European Economic Area (the "EEA") or in the United Kingdom (each, a "Relevant State") will only be made to a legal entity which is a qualified investor under the Prospectus Regulation ("Qualified Investors"). Accordingly any person making or intending to make an offer in that Relevant State of Notes which are the subject of the offering contemplated in this pricing supplement, the accompanying product supplement, the accompanying prospectus and the accompanying prospectus supplement may only do so with respect to Qualified Investors. Neither BofA Finance nor BAC has authorized, nor does it authorize, the making of any offer of Notes other than to Qualified Investors. The expression "Prospectus Regulation" means Regulation (EU) 2017/1129.

PROHIBITION OF SALES TO EEA RETAIL INVESTORS - The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA. For these purposes: (a) a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU, as amended ("MiFID II"); or (ii) a customer within the meaning of Directive (EU) 2016/97 (the Insurance Distribution Directive) where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Regulation; and (b) the expression "offer" includes the communication in any form and by any means of sufficient information on the terms of the offer and the Notes to be offered so as to enable an investor to decide to purchase or subscribe for the Notes. Consequently no key information document required by Regulation (EU) No 1286/2014, as amended (the "PRIIPs Regulation") for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

PROHIBITION OF SALES TO UNITED KINGDOM RETAIL INVESTORS - The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom. For these purposes: (a) a retail investor means a person who is neither: (i) a professional client as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic

law in the United Kingdom; nor (ii) a qualified investor as defined in paragraph 15 of Schedule 1 to the Public Offers and Admissions to Trading Regulations 2024 (as may be amended from time to time); and (b) the expression "offer" includes the communication in any form and by any means of sufficient information on the terms of the offer and the Notes to be offered so as to enable an investor to decide to purchase or subscribe for the Notes. Consequently no key information document required by Regulation (EU) No 1286/2014, as amended (the "PRIIPs Regulation") for offering or selling the Notes or otherwise making them available to retail investors in the United Kingdom has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the United Kingdom may be unlawful under the PRIIPs Regulation.

United Kingdom

The communication of this pricing supplement, the accompanying product supplement, the accompanying prospectus supplement, the accompanying prospectus and any other document or materials relating to the issue of the Notes offered hereby is not being made, and such documents and/or materials have not been approved, by an authorized person for the purposes of Section 21 of the United Kingdom's Financial Services and Markets Act 2000, as amended (the "FSMA"). Accordingly, such documents and/or materials are not being distributed to, and must not be passed on to, the general public in the United Kingdom. The communication of such documents and/or materials as a financial promotion is only being made to those persons in the United Kingdom who have professional experience in matters relating to investments and who fall within the definition of investment professionals (as defined in Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005, as amended (the "Financial Promotion Order")), or who fall within Article 49(2)(a) to (d) of the Financial Promotion Order, or who are any other persons to whom it may otherwise lawfully be made under the Financial Promotion Order (all such persons together being referred to as "Relevant Persons"). In the United Kingdom, the Notes offered hereby are only available to, and any investment or investment activity to which this pricing supplement, the accompanying product supplement, the accompanying prospectus supplement and the accompanying prospectus relates will be engaged in only with, Relevant Persons.

Any invitation or inducement to engage in investment activity (within the meaning of Section 21 of the FSMA) in connection with the issue or sale of the Notes may only be communicated or caused to be communicated in circumstances in which Section 21(1) of the FSMA does not apply to BofA Finance, as Issuer, or BAC, as Guarantor.

All applicable provisions of the FSMA must be complied with in respect to anything done by any person in relation to the Notes in, from or otherwise involving the United Kingdom.

Structuring the Notes

The Notes are our debt securities, the return on which is linked to the performance of the Underlyings. The related guarantee is BAC's obligation. As is the case for all of our and BAC's respective debt securities, including our market-linked notes, the economic terms of the Notes reflect our and BAC's actual or perceived creditworthiness at the time of pricing. In addition, because market-linked notes result in increased operational, funding and liability management costs to us and BAC, BAC typically borrows the funds under these types of notes at a rate, which we refer to in this pricing supplement as BAC's internal funding rate, that is more favorable to BAC than the rate that it might pay for a conventional fixed or floating rate debt security. This generally relatively lower internal funding rate, which is reflected in the economic terms of the Notes, along with the fees and charges associated with market-linked notes, typically results in the initial estimated value of the Notes on the pricing date being less than their public offering price.

In order to meet our payment obligations on the Notes, at the time we issue the Notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with BofAS or one of our other affiliates. The terms of these hedging arrangements are determined based upon terms provided by BofAS and its affiliates, and take into account a number of factors, including our and BAC's creditworthiness, interest rate movements, the volatility of the Underlyings, the tenor of the Notes and the hedging arrangements. The economic terms of the Notes and their initial estimated value depend in part on the terms of these hedging arrangements.

BofAS has advised us that the hedging arrangements will include hedging related charges, reflecting the costs associated with, and our affiliates' profit earned from, these hedging arrangements. Since hedging entails risk and may be influenced by unpredictable market forces, actual profits or losses from these hedging transactions may be more or less than any expected amounts.

U.S. Federal Income Tax Summary

The following summary of the material U.S. federal income and estate tax considerations of the acquisition, ownership, and disposition of the Notes supplements, and to the extent inconsistent supersedes, the discussion under "U.S. Federal Income Tax Considerations" in the accompanying prospectus and is not exhaustive of all possible tax considerations. This summary is based upon the Internal Revenue Code of 1986, as amended (the "Code"), regulations promulgated under the Code by the U.S. Treasury Department ("Treasury") (including proposed and temporary regulations), rulings, current administrative interpretations and official pronouncements of the IRS, and judicial decisions, all as currently in effect and all of which are subject to differing interpretations or to change, possibly with retroactive effect. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax consequences described below. This summary does not include any description of the tax laws of any state or local governments, or of any foreign government, that may be applicable to a particular holder.

Although the Notes are issued by us, they will be treated as if they were issued by BAC for U.S. federal income tax purposes. Accordingly throughout this tax discussion, references to "we," "our" or "us" are generally to BAC unless the context requires otherwise.

This summary is directed solely to U.S. Holders and Non-U.S. Holders (each, as defined in the accompanying prospectus) that, except as otherwise specifically noted, will purchase the Notes upon original issuance and will hold the Notes as capital assets within the meaning of Section 1221 of the Code, which generally means property held for investment, and that are not excluded from the discussion under "U.S. Federal Income Tax Considerations" in the accompanying prospectus.

You should consult your own tax advisor concerning the U.S. federal income tax consequences to you of acquiring, owning, and disposing of the Notes, as well as any tax consequences arising under the laws of any state, local, foreign, or other tax jurisdiction and the possible effects of changes in U.S. federal or other tax laws.

General

Although there is no statutory, judicial, or administrative authority directly addressing the characterization of the Notes, we intend to treat the Notes for all tax purposes as contingent income-bearing single financial contracts with respect to the Underlyings and under the terms of the Notes, we and every investor in the Notes agree, in the absence of an administrative determination or judicial ruling to the contrary, to treat the Notes in accordance with such characterization. In the opinion of our counsel, Sidley Austin LLP, it is reasonable to treat the Notes as contingent income-bearing single financial contracts with respect to the Underlyings. This discussion assumes that the Notes constitute contingent income-bearing single financial contracts with respect to the Underlyings for U.S. federal income tax purposes. If the Notes did not constitute contingent income-bearing single financial contracts, the tax consequences described below would be materially different.

This characterization of the Notes is not binding on the IRS or the courts. No statutory, judicial, or administrative authority directly addresses the characterization of the Notes or any similar instruments for U.S. federal income tax purposes, and no ruling is being requested from the IRS with respect to their proper characterization and treatment. Due to the absence of authorities on point, significant aspects of the U.S. federal income tax consequences of an investment in the Notes are not certain, and no assurance can be given that the IRS or any court will agree with the characterization and tax treatment described in this pricing supplement. Accordingly, you are urged to consult your tax advisor regarding all aspects of the U.S. federal income tax consequences of an investment in the Notes, including possible alternative characterizations.

Unless otherwise stated, the following discussion is based on the characterization described above. The discussion in this section assumes that there is a significant possibility of a significant loss of principal on an investment in the Notes.

We will not attempt to ascertain whether the issuer of any Underlying would be treated as a "passive foreign investment company" ("PFIC"), within the meaning of Section 1297 of the Code, or a United States real property holding corporation, within the meaning of Section 897(c) of the Code. If the issuer of any Underlying were so treated, certain adverse U.S. federal income tax consequences could possibly apply to a holder of the Notes. You should refer to information filed with the SEC by the issuers of the Underlyings and consult your tax advisor regarding the possible consequences to you, if any, if the issuer of any Underlying is or becomes a PFIC or is or becomes a United States real property holding corporation.

U.S. Holders

Although the U.S. federal income tax treatment of any Contingent Coupon Payment on the Notes is uncertain, we intend to take the position, and the following discussion assumes, that any Contingent Coupon Payment constitutes taxable ordinary income to a U.S. Holder at the time received or accrued in accordance with the U.S. Holder's regular method of accounting. By purchasing the Notes you agree, in the absence of an administrative determination or judicial ruling to the contrary, to treat any Contingent Coupon Payment as described in the preceding sentence.

Upon receipt of a cash payment at maturity or upon a sale, exchange, or redemption of the Notes prior to maturity, a U.S. Holder generally will recognize capital gain or loss equal to the difference between the amount realized (other than amounts representing any Contingent Coupon Payment, which would be taxed as described above) and the U.S. Holder's tax basis in the Notes. A U.S. Holder's tax basis in the Notes will equal the amount paid by that holder to acquire them. Subject to the discussion below concerning the possible application of the "constructive ownership" rules of Section 1260 of the Code, this capital gain or loss generally will be long-term capital gain or loss if the U.S. Holder held the Notes for more than one year. The deductibility of capital losses is subject to limitations.

Contingent Income Auto-Callable Yield Notes Linked to the Least Performing of the Common Stock of SLB N.V. (SLB Limited) and the United States Oil Fund, LP

Possible Application of Section 1260 of the Code. Since one Underlying is the type of financial asset described under Section 1260 of the Code (including, among others, any equity interest in pass-through entities such as exchange traded funds, regulated investment companies, real estate investment trusts, partnerships, and passive foreign investment companies, each a "Section 1260 Financial Asset"), while the matter is not entirely clear, there may exist a risk that an investment in the Notes will be treated , in whole or in part, as a "constructive ownership transaction" to which Section 1260 of the Code applies. If Section 1260 of the Code applies, all or a portion of any long-term capital gain recognized by a U.S. Holder in respect of the Notes will be recharacterized as ordinary income (the "Excess Gain"). In addition, an interest charge will also apply to any deemed underpayment of tax in respect of any Excess Gain to the extent such gain would have resulted in gross income inclusion for the U.S. Holder in taxable years prior to the taxable year of the sale, exchange, redemption or settlement (assuming such income accrued at a constant rate equal to the applicable federal rate as of the date of sale, exchange, redemption or settlement).

If an investment in the Notes is treated as a constructive ownership transaction, it is not clear to what extent any long-term capital gain of a U.S. Holder in respect of the Notes will be recharacterized as ordinary income. It is possible, for example, that the amount of the Excess Gain (if any) that would be recharacterized as ordinary income in respect of the Notes will equal the excess of (i) any long-term capital gain recognized by the U.S. Holder in respect of the Notes and attributable to Section 1260 Financial Assets, over (ii) the "net underlying long-term capital gain" (as defined in Section 1260 of the Code) such U.S. Holder would have had if such U.S. Holder had acquired an amount of the corresponding Section 1260 Financial Assets at fair market value on the original issue date for an amount equal to the portion of the issue price of the Notes attributable to the corresponding Section 1260 Financial Assets and sold such amount of Section 1260 Financial Assets at maturity or upon sale, exchange or redemption of the Notes at fair market value. Unless otherwise established by clear and convincing evidence, the net underlying long-term capital gain is treated as zero and therefore it is possible that all long-term capital gain recognized by a U.S. Holder in respect of the Notes will be recharacterized as ordinary income if Section 1260 of the Code applies to an investment in the Notes. U.S. Holders should consult their tax advisors regarding the potential application of Section 1260 of the Code to an investment in the Notes.

As described below, the IRS, as indicated in Notice 2008-2 (the "Notice"), is considering whether Section 1260 of the Code generally applies or should apply to the Notes, including in situations where the Underlyings are not the type of financial asset described under Section 1260 of the Code.

Alternative Tax Treatments. Due to the absence of authorities that directly address the proper tax treatment of the Notes, prospective investors are urged to consult their tax advisors regarding all possible alternative tax treatments of an investment in the Notes. In particular, the IRS could seek to subject the Notes to the Treasury regulations governing contingent payment debt instruments. If the IRS were successful in that regard, the timing and character of income on the Notes would be affected significantly. Among other things, a U.S. Holder would be required to accrue original issue discount every year at a "comparable yield" determined at the time of issuance. In addition, any gain realized by a U.S. Holder at maturity or upon a sale, exchange, or redemption of the Notes generally would be treated as ordinary income, and any loss realized at maturity or upon a sale, exchange, or redemption of the Notes generally would be treated as ordinary loss to the extent of the U.S. Holder's prior accruals of original issue discount, and as capital loss thereafter.

In addition, it is possible that the Notes could be treated as a unit consisting of a deposit and a put option written by the Note holder, in which case the timing and character of income on the Notes would be affected significantly.

The Notice sought comments from the public on the taxation of financial instruments currently taxed as "prepaid forward contracts." This Notice addresses instruments such as the Notes. According to the Notice, the IRS and Treasury are considering whether a holder of an instrument such as the Notes should be required to accrue ordinary income on a current basis, regardless of whether any payments are made prior to maturity. It is not possible to determine what guidance the IRS and Treasury will ultimately issue, if any. Any such future guidance may affect the amount, timing and character of income, gain, or loss in respect of the Notes, possibly with retroactive effect.

The IRS and Treasury are also considering additional issues, including whether additional gain or loss from such instruments should be treated as ordinary or capital, whether foreign holders of such instruments should be subject to withholding tax on any deemed income accruals, whether Section 1260 of the Code, concerning certain "constructive ownership transactions," generally applies or should generally apply to such instruments, and whether any of these determinations depend on the nature of the underlying asset.

In addition, proposed Treasury regulations require the accrual of income on a current basis for contingent payments made under certain notional principal contracts. The preamble to the regulations states that the "wait and see" method of accounting does not properly reflect the economic accrual of income on those contracts, and requires current accrual of income for some contracts already in existence. While the proposed regulations do not apply to prepaid forward contracts, the preamble to the proposed regulations expresses the view that similar timing issues exist in the case of prepaid forward contracts. If the IRS or Treasury publishes future guidance requiring current economic accrual for contingent payments on prepaid forward contracts, it is possible that you could be required to accrue income over the term of the Notes.

Because of the absence of authority regarding the appropriate tax characterization of the Notes, it is also possible that the IRS could seek to characterize the Notes in a manner that results in tax consequences that are different from those described above. For example, the IRS could possibly assert that any gain or loss that a holder may recognize at maturity or upon the sale, exchange, or redemption of the Notes should be treated as ordinary gain or loss.

Non-U.S. Holders

Because the U.S. federal income tax treatment of the Notes (including any Contingent Coupon Payment) is uncertain, we (or the applicable paying agent) will withhold U.S. federal income tax at a 30% rate (or at a lower rate under an applicable income tax treaty) on the entire amount of any Contingent Coupon Payment made unless such payments are effectively connected with the conduct by the Non-U.S. Holder of a trade or business in the U.S. (in which case, to avoid withholding, the Non-U.S. Holder will be required to provide a Form W-8ECI). We (or the applicable paying agent) will not pay any additional amounts in respect of such withholding. To claim benefits under an income tax treaty, a Non-U.S. Holder must obtain a taxpayer identification number and certify as to its eligibility under the appropriate treaty's limitations on benefits article, if applicable. In addition, special rules may apply to claims for treaty benefits made by Non-U.S. Holders that are entities rather than individuals. The availability of a lower rate of withholding under an applicable income tax treaty will depend on whether such rate applies to the characterization of the payments under U.S. federal income tax laws. A Non-U.S. Holder that is eligible for a reduced rate of U.S. federal withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS.

Except as discussed below, a Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax for amounts paid in respect of the Notes (not including, for the avoidance of doubt, amounts representing any Contingent Coupon Payment which would be subject to the rules discussed in the previous paragraph) upon the sale, exchange, or redemption of the Notes or their settlement at maturity, provided that the Non-U.S. Holder complies with applicable certification requirements and that the payment is not effectively connected with the conduct by the Non-U.S. Holder of a U.S. trade or business. Notwithstanding the foregoing, gain from the sale, exchange, or redemption of the Notes or their settlement at maturity may be subject to U.S. federal income tax if that Non-U.S. Holder is a non-resident alien individual and is present in the U.S. for 183 days or more during the taxable year of the sale, exchange, redemption, or settlement and certain other conditions are satisfied.

If a Non-U.S. Holder of the Notes is engaged in the conduct of a trade or business within the U.S. and if any Contingent Coupon Payment and gain realized on the settlement at maturity, or upon sale, exchange, or redemption of the Notes, is effectively connected with the conduct of such trade or business (and, if certain tax treaties apply, is attributable to a permanent establishment maintained by the Non-U.S. Holder in the U.S.), the Non-U.S. Holder, although exempt from U.S. federal withholding tax, generally will be subject to U.S. federal income tax on such Contingent Coupon Payment and gain on a net income basis in the same manner as if it were a U.S. Holder. Such Non-U.S. Holders should read the material under the heading "-U.S. Holders," for a description of the U.S. federal income tax consequences of acquiring, owning, and disposing of the Notes. In addition, if such Non-U.S. Holder is a foreign corporation, it may also be subject to a branch profits tax equal to 30% (or such lower rate provided by any applicable tax treaty) of a portion of its earnings and profits for the taxable year that are effectively connected with its conduct of a trade or business in the U.S., subject to certain adjustments.

A "dividend equivalent" payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a Non-U.S. Holder. Under Treasury regulations, payments (including deemed payments) with respect to equity-linked instruments ("ELIs") that are "specified ELIs" may be treated as dividend equivalents if such specified ELIs reference an interest in an "underlying security," which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, IRS guidance provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2027. Based on our determination that the Notes are not delta-one instruments, Non-U.S. Holders should not be subject to withholding on dividend equivalent payments, if any, under the Notes. However, it is possible that the Notes could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Underlyings or the Notes, and following such occurrence the Notes could be treated as subject to withholding on dividend equivalent payments. Non-U.S. Holders that enter, or have entered, into other transactions in respect of the Underlyings or the Notes should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the Notes and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.

As discussed above, alternative characterizations of the Notes for U.S. federal income tax purposes are possible. Should an alternative characterization, by reason of change or clarification of the law, by regulation or otherwise, cause payments as to the Notes to become subject to withholding tax in addition to the withholding tax described above, tax will be withheld at the applicable statutory rate. Prospective Non-U.S. Holders should consult their own tax advisors regarding the tax consequences of such alternative characterizations.

U.S. Federal Estate Tax. Under current law, while the matter is not entirely clear, individual Non-U.S. Holders, and entities whose property is potentially includible in those individuals' gross estates for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty benefit, a Note is likely to be treated as U.S. situs property, subject to U.S. federal estate tax. These individuals and entities should consult their own tax advisors regarding the U.S. federal estate tax consequences of investing in a Note.
