Linked to the Least Performing of the Invesco QQQ Trust^SM, Series 1, the VanEck^® Semiconductor ETF and the iShares^® Expanded Tech-Software Sector ETF

•The Enhanced Return Notes Linked to the Least Performing of the Invesco QQQ Trust^SM, Series 1, the VanEck^® Semiconductor ETF and the iShares^® Expanded Tech-Software Sector ETF, due February 28, 2031 (the "Notes") are expected to price on February 25, 2026 and expected to issue on March 2, 2026.

•Approximate 5 year term.

•Payment on the Notes will depend on the individual performance of the Invesco QQQ Trust^SM, Series 1, the VanEck^® Semiconductor ETF and the iShares^® Expanded Tech-Software Sector ETF (each an "Underlying").

•If the Ending Value of each Underlying is greater than 100% of its Starting Value, at maturity, you will receive 240.00% upside exposure to increases in the value of the Least Performing Underlying.

•If any Underlying declines from its Starting Value, at maturity your investment will be subject to 1:1 downside exposure to decreases in the value of the Least Performing Underlying, with up to 100% of the principal at risk.

•Any payment on the Notes is subject to the credit risk of BofA Finance LLC ("BofA Finance" or the "Issuer"), as issuer of the Notes, and Bank of America Corporation ("BAC" or the "Guarantor"), as guarantor of the Notes.

•No periodic interest payments.

•The Starting Values of the Underlyings were determined on February 24, 2026 (the "Strike Date"). The Starting Value of each Underlying is an intraday price on the Strike Date, as determined by the calculation agent. The Starting Value of each Underlying may be higher or lower than its respective closing price on the pricing date.

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

•CUSIP No. 09711NXY1.

The initial estimated value of the Notes as of the pricing date is expected to be between $935.00 and $985.00 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-6 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-6 of this pricing supplement, page PS-3 of the accompanying product supplement, 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 $999.70 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 $0.30, resulting in proceeds, before expenses, to BofA Finance of as low as $999.70 per $1,000.00 in principal amount of Notes.

Terms of the Notes

Enhanced Return Notes Linked to the Least Performing of the Invesco QQQ Trust^SM, Series 1, the VanEck^® Semiconductor ETF and the iShares^® Expanded Tech-Software Sector ETF

* Subject to change.

Payment on the Notes depends on the credit risk of BofA Finance, as Issuer, and BAC, as Guarantor, and on the performance of each Underlying. 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-6), 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 PS-6 and "Structuring the Notes" on PS-27.

Redemption Amount Determination

On the Maturity Date, you will receive a cash payment per $1,000.00 in principal amount of Notes determined as follows:

All payments described above are subject to the credit risk of BofA Finance, as Issuer, and BAC, as Guarantor.

Hypothetical Payout Profile and Examples of Payments at Maturity

Enhanced Return Notes Table

The following table is for purposes of illustration only. It 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 Starting Value of 100 for the Least Performing Underlying, the Upside Participation Rate of 240.00% 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, Starting Values and Ending Values of the Underlyings, 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 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 Ending Value of any Underlying is less than its Starting 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 some or all of your investment in the Notes.

•The Notes do not bear interest. Unlike a conventional debt security, no interest payments will be paid over the term of the Notes, regardless of the extent to which the Ending Value of the Least Performing Underlying exceeds its Starting Value.

•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.

•The Redemption Amount will not reflect changes in the prices of the Underlyings other than on the Valuation Date. The prices of the Underlyings during the term of the Notes other than on the Valuation Date will not be reflected in the calculation of the Redemption Amount. 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 calculate the Redemption Amount by comparing only to the Ending Value for each Underlying. No other prices of the Underlyings will be taken into account. As a result, if the Ending Value of the Least Performing Underlying is less than its Starting Value, you will receive less than the principal amount at maturity even if the price of each Underlying was always above its Starting 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 some or all of your investment in the Notes even if the Ending Value of one Underlying is greater than or equal to its Starting Value. Your Notes are linked to the least performing of the Underlyings, and a change in the price of one Underlying may not correlate with changes in the prices of the other Underlyings. The Notes are not linked to a basket composed of the Underlyings, where the depreciation in the price of one Underlying could be offset to some extent by the appreciation in the prices of the other Underlyings. In the case of the Notes, the individual performance of each Underlying would not be combined, and the depreciation in the price of one Underlying would not be offset by any appreciation in the prices of the other Underlyings. Even if the Ending Value of an Underlying is at or above its Starting Value, you will lose some or all of your investment in the Notes if the Ending Value of the Least Performing Underlying is below its Starting 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 prices 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 whose value is derived from 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 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 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 prices of the Underlyings in a manner that could be adverse to your investment in the Notes. On or before the Strike 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 have adversely affected the prices of the Underlyings. Consequently, the prices of the Underlyings may change subsequent to the Strike 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 may have engaged in hedging activities that could have adversely affected the prices of the Underlyings on the Strike 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 prices 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.

Underlying-related Risks

•Adverse conditions in the semiconductor production and equipment sector may reduce your return on the Notes. All or substantially all of the stocks held by the SMH are issued by companies whose primary line of business is directly associated with the semiconductor production and equipment sector. The SMH is subject to the risk that companies that are in the semiconductor production and equipment sector may be similarly affected by particular economic or market events. As product cycles shorten and manufacturing

Enhanced Return Notes Linked to the Least Performing of the Invesco QQQ Trust^SM, Series 1, the VanEck^® Semiconductor ETF and the iShares^® Expanded Tech-Software Sector ETF

capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Semiconductor companies are vulnerable to wide fluctuations in securities prices due to rapid product obsolescence. Many semiconductor companies may not successfully introduce new products, develop and maintain a loyal customer base or achieve general market acceptance for their products, and failure to do so could have a material adverse effect on their business, results of operations and financial condition. Reduced demand for end-user products, underutilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor production and equipment sector. Semiconductor companies typically face high capital costs and such companies may need additional financing, which may be difficult to obtain. They also may be subject to risks relating to research and development costs and the availability and price of components. Moreover, they may be heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. Some of the companies involved in the semiconductor production and equipment sector are also engaged in other lines of business unrelated to the semiconductor business, and they may experience problems with these lines of business, which could adversely affect their operating results. The international operations of many semiconductor companies expose them to risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, tariffs and trade disputes, competition from subsidized foreign competitors with lower production costs and other risks inherent to international business. The semiconductor production and equipment sector is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. Companies in the semiconductor production and equipment sector also may be subject to competition from new market entrants. The stock prices of companies in the semiconductor production and equipment sector have been and will likely continue to be extremely volatile compared to the overall market. These factors could affect the semiconductor production and equipment sector and could affect the value of the equity securities held by the SMH and the price of the SMH during the term of the Notes, which may adversely affect the value of your Notes.

•The Notes are subject to risks associated with foreign securities markets. The QQQ holds certain foreign equity securities. You should be aware that investments in securities linked to the value of foreign equity securities involve particular risks. The foreign securities markets comprising the QQQ may have less liquidity and may be more volatile than U.S. or other securities markets and market developments may affect foreign markets differently from U.S. or other securities markets. Direct or indirect government intervention to stabilize these foreign securities markets, as well as cross-shareholdings in foreign companies, may affect trading prices and volumes in these markets. Also, there is generally less publicly available information about foreign companies than about those U.S. companies that are subject to the reporting requirements of the SEC, and foreign companies are subject to accounting, auditing and financial reporting standards and requirements that differ from those applicable to U.S. reporting companies.

Prices of securities in foreign countries are subject to political, economic, financial and social factors that apply in those geographical regions. These factors, which could negatively affect those securities markets, include the possibility of recent or future changes in a foreign government's economic and fiscal policies, the possible imposition of, or changes in, currency exchange laws or other laws or restrictions applicable to foreign companies or investments in foreign equity securities and the possibility of fluctuations in the rate of exchange between currencies, the possibility of outbreaks of hostility and political instability and the possibility of natural disaster or adverse public health developments in the region. Moreover, foreign economies may differ favorably or unfavorably from the U.S. economy in important respects such as growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency.

•Adverse conditions in the information technology sector may reduce your return on the Notes. All of the stocks held by the IGV are issued by companies in the information technology sector. Market or economic factors impacting technology companies and companies that rely heavily on technological advances could have a major effect on the value of the IGV's investments. The prices of stocks of technology companies and companies that rely heavily on technology are particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability. Additionally, companies in the technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action. Companies in the application software industry, in particular, may also be negatively affected by the decline or fluctuation of subscription renewal rates for their products and services, which may have an adverse effect on profit margins. Companies in the systems software industry may be adversely affected by, among other things, actual or perceived security vulnerabilities in their products and services, which may result in individual or class action lawsuits, state or federal enforcement actions and other remediation costs. Any of these factors may have an adverse effect on the return on the Notes. Accordingly, by investing in the Notes, you will not benefit from the diversification which could result from an investment linked to companies that operate in multiple sectors.

•The stocks held by the SMH are concentrated in one sector. The SMH holds securities issued by companies in the semiconductor production and equipment sector. As a result, some of the stocks that will 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 securities held by the SMH, the return on an investment in the Notes will be subject to certain risks associated with a direct equity investment in companies in this sector. Accordingly, by investing in the Notes, you will not benefit from the diversification which could result from an investment linked to companies that operate in multiple sectors.

•The stocks held by the IGV are concentrated in one sector. The IGV holds securities issued by companies in the technology sector. As a result, some of the stocks that will 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 securities held by the IGV, the return on an investment in the Notes will be subject to certain risks associated with a direct equity investment in companies in this sector. Accordingly, by investing in the Notes, you will not benefit from the diversification which could result from an investment linked to companies that operate in multiple sectors.

•The performance of an Underlying may not correlate with the performance of its underlying index as well as the net asset value per share or unit of the Underlying, especially during periods of market volatility. The performance of an Underlying and that of its underlying index 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 an Underlying may not fully replicate or may, in certain circumstances, diverge significantly from the performance of its underlying index. This could be due to, for example, the Underlying not holding all or substantially all of the underlying assets included in its underlying index and/or holding assets that are not included in its underlying index, the temporary unavailability of certain securities in the secondary market, the performance of any derivative instruments held by the Underlying, differences in trading hours between the Underlying (or the underlying assets held by the Underlying) and its underlying index, or 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 each Underlying are traded on a securities exchange and are subject to market supply and investor demand, the market price of one share or unit of an Underlying may differ from its net asset value per share or unit; shares or units of the Underlying may trade at, above, or below its net asset value per share or unit. During periods of market volatility, securities held by an Underlying may be unavailable in the secondary market, market participants may be unable to calculate accurately the net asset value per share or unit of the Underlying and the liquidity of the Underlying may be adversely affected. Market volatility may also disrupt the ability of market participants to trade shares or units of the Underlying. 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 Underlying. As a result, under these circumstances, the market value of shares or units of the Underlying may vary substantially from the net asset value per share or unit of the Underlying.

•The anti-dilution adjustments will be limited. The calculation agent may adjust the Price Multiplier of an Underlying and other terms of the Notes to reflect certain actions by an Underlying, 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 an Underlying 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 an Underlying may adjust that Underlying in a way that affects its prices, 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 an Underlying can add, delete, or substitute the components included in that Underlying or make other methodological changes that could change its price. 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 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 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.

The Underlyings

All disclosures contained in this pricing supplement regarding the Underlyings, including, without limitation, their make-up, method of calculation, and changes in their components, have been derived from publicly available sources. The information reflects the policies of, and is subject to change by, the investment advisor of the QQQ, the investment advisor of the SMH and the investment advisor of the IGV (collectively, the "Investment Advisors"). The Investment Advisors, which license the copyright and all other rights to the respective Underlyings, have no obligation to continue to publish, and may discontinue publication of, the Underlyings. The consequences of any Investment Advisor discontinuing publication of the applicable Underlying are discussed in "Description of the Notes - Anti-Dilution and Discontinuance Adjustments Relating to ETFs - 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 any Underlying or any successor underlying. None of us, the Guarantor, BofAS or any of our other affiliates makes any representation to you as to the future performance of the Underlyings. You should make your own investigation into the Underlyings.

The Invesco QQQ Trust^SM, Series 1

The Invesco QQQ Trust^SM, Series 1 is a unit investment trust that issues securities called "trust units" or "units." The QQQ is organized under New York law and is governed by a standard terms and conditions of trust between The Bank of New York Mellon (the "Trustee") and NASDAQ Global Funds, the predecessor sponsor to Invesco Capital Management (the "Sponsor") , dated and executed as of March 1, 1999, as amended (the "Terms and Conditions"). The Trustee and the Sponsor are also sponsors to a trust indenture agreement of the Trust dated as of March 4, 1999, as amended (the "Trust Agreement"). The QQQ is an investment company registered under the Investment Company Act of 1940, as amended. The QQQ commenced operations on March 4, 1999. The units of the Invesco QQQ Trust^SM, Series 1 trade on the NASDAQ Global Market under the symbol "QQQ."

A trust unit represents an undivided ownership interest in a portfolio consisting of all of the common stocks of its underlying index, the Nasdaq-100^® Index (the "NDX"). The QQQ intends to provide investment results that, before fees and expenses, generally correspond to the price and yield performance of the NDX. The expenses of the QQQ are accrued daily and reflected in the net asset value of the QQQ. After reflecting waivers (including earnings credits as a result of uninvested cash balances of the QQQ), the QQQ currently is accruing ordinary operating expenses at an annual rate of 0.20%.

The units of the QQQ are registered under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Accordingly, information filed with the SEC relating to the QQQ, including its periodic financial reports, may be found on the SEC website.

The Nasdaq-100^® Index

The NDX is intended to measure the performance of the 100 largest domestic and international non-financial securities listed on The Nasdaq Stock Market ("NASDAQ") based on market capitalization. The NDX reflects companies across major industry groups including computer hardware and software, telecommunications, retail/wholesale trade and biotechnology. It does not contain securities of financial companies including investment companies.

The NDX began trading on January 31, 1985 at a base value of 125.00. The NDX is calculated and published by Nasdaq, Inc. In administering the NDX, Nasdaq, Inc. will exercise reasonable discretion as it deems appropriate.

Underlying Stock Eligibility Criteria

NDX eligibility is limited to specific security types only. The security types eligible for the NDX include foreign or domestic common stocks, ordinary shares, ADRs and tracking stocks. Security types not included in the NDX are closed-end funds, convertible debt securities, exchange traded funds, limited liability companies, limited partnership interests, preferred stocks, rights, shares or units of beneficial interest, warrants, units, and other derivative securities. The NDX does not contain securities of investment companies. For purposes of the NDX eligibility criteria, if the security is a depositary receipt representing a security of a non-U.S. issuer, then references to the "issuer" are references to the issuer of the underlying security.

Initial Eligibility Criteria

To be eligible for initial inclusion in the NDX, a security must be listed on NASDAQ and meet the following criteria:

•the security's U.S. listing must be exclusively on the Nasdaq Global Select Market or the Nasdaq Global Market (unless the security was dually listed on another U.S. market prior to January 1, 2004 and has continuously maintained such listing);

•the security must be of a non-financial company;

•the security may not be issued by an issuer currently in bankruptcy proceedings;

•the security must have a minimum three-month average daily trading volume of at least 200,000 shares;

•if the issuer of the security is organized under the laws of a jurisdiction outside the U.S., then such security must have listed options on a recognized options market in the U.S. or be eligible for listed-options trading on a recognized options market in the U.S.;

•the issuer of the security may not have entered into a definitive agreement or other arrangement which would likely result in the security no longer being eligible for inclusion in the NDX;

•the issuer of the security may not have annual financial statements with an audit opinion that is currently withdrawn; and

•the issuer of the security must have "seasoned" on NASDAQ, the New York Stock Exchange or NYSE Amex. Generally, a company is considered to be seasoned if it has been listed on a market for at least three full months (excluding the first month of initial listing).

Continued Eligibility Criteria

In addition, to be eligible for continued inclusion in the NDX, the following criteria apply:

•the security's U.S. listing must be exclusively on the Nasdaq Global Select Market or the Nasdaq Global Market;

•the security must be of a non-financial company;

•the security may not be issued by an issuer currently in bankruptcy proceedings;

•the security must have a minimum three-month average daily trading volume of at least 200,000 shares;

•if the issuer of the security is organized under the laws of a jurisdiction outside the U.S., then such security must have listed options on a recognized options market in the U.S. or be eligible for listed-options trading on a recognized options market in the U.S. (measured annually during the ranking review process);

•the security must have an adjusted market capitalization equal to or exceeding 0.10% of the aggregate adjusted market capitalization of the NDX at each month-end. In the event a company does not meet this criterion for two consecutive month-ends, it will be removed from the NDX effective after the close of trading on the third Friday of the following month; and

•the issuer of the security may not have annual financial statements with an audit opinion that is currently withdrawn.

Computation of the NDX

The value of the NDX equals the aggregate value of the NDX share weights (the "NDX Shares") of each of the NDX securities multiplied by each such security's last sale price (last sale price refers to the last sale price on NASDAQ), and divided by the divisor of the NDX. If trading in an NDX security is halted while the market is open, the last traded price for that security is used for all NDX computations until trading resumes. If trading is halted before the market is open, the previous day's last sale price is used. The formula for determining the NDX value is as follows:

The NDX is ordinarily calculated without regard to cash dividends on NDX securities. The NDX is calculated during the trading day and is disseminated once per second from 09:30:01 to 17:16:00 ET. The closing level of the NDX may change up until 17:15:00 ET due to corrections to the last sale price of the NDX securities. The official closing value of the NDX is ordinarily disseminated at 17:16:00 ET.

NDX Maintenance

Changes to NDX Constituents

Changes to the NDX constituents may be made during the annual ranking review. In addition, if at any time during the year other than the annual review, it is determined that an NDX security issuer no longer meets the criteria for continued inclusion in the NDX, or is otherwise determined to have become ineligible for continued inclusion in the NDX, it is replaced with the largest market capitalization issuer not currently in the NDX that meets the applicable eligibility criteria for initial inclusion in the NDX.

Ordinarily, a security will be removed from the NDX at its last sale price. However, if at the time of its removal the NDX security is halted from trading on its primary listing market and an official closing price cannot readily be determined, the NDX security may, in Nasdaq, Inc.'s discretion, be removed at a price of $0.00000001 ("zero price"). This zero price will be applied to the NDX security after the close of the market but prior to the time the official closing value of the NDX is disseminated.

Divisor Adjustments

The divisor is adjusted to ensure that changes in the NDX constituents either by corporate actions (that adjust either the price or shares of an NDX security) or NDX participation outside of trading hours do not affect the value of the NDX. All divisor changes occur after the close of the applicable index security markets.

Quarterly NDX Rebalancing

The NDX will be rebalanced on a quarterly basis if it is determined that (1) the current weight of the single NDX security with the largest market capitalization is greater than 24.0% of the NDX or (2) the collective weight of those securities whose individual current weights are in excess of 4.5% exceeds 48.0% of the NDX. In addition, a "special rebalancing" of the NDX may be conducted at any time if Nasdaq, Inc. determines it necessary to maintain the integrity and continuity of the NDX. If either one or both of the above weight distribution conditions are met upon quarterly review, or Nasdaq, Inc. determines that a special rebalancing is necessary, a weight rebalancing will be performed.

If the first weight distribution condition is met and the current weight of the single NDX security with the largest market capitalization is greater than 24.0%, then the weights of all securities with current weights greater than 1.0% ("large securities") will be scaled down proportionately toward 1.0% until

Enhanced Return Notes Linked to the Least Performing of the Invesco QQQ Trust^SM, Series 1, the VanEck^® Semiconductor ETF and the iShares^® Expanded Tech-Software Sector ETF

the adjusted weight of the single largest NDX security reaches 20.0%.

If the second weight distribution condition is met and the collective weight of those securities whose individual current weights are in excess of 4.5% (or adjusted weights in accordance with the previous step, if applicable) exceeds 48.0% of the NDX, then the weights of all such large securities in that group will be scaled down proportionately toward 1.0% until their collective weight, so adjusted, is equal to 40.0%.

The aggregate weight reduction among the large securities resulting from either or both of the rebalancing steps above will then be redistributed to those securities with weightings of less than 1.0% ("small securities") in the following manner. In the first iteration, the weight of the largest small security will be scaled upwards by a factor which sets it equal to the average NDX weight of 1.0%. The weights of each of the smaller remaining small securities will be scaled up by the same factor reduced in relation to each security's relative ranking among the small securities such that the smaller the NDX security in the ranking, the less its weight will be scaled upward. This is intended to reduce the market impact of the weight rebalancing on the smallest component securities in the NDX.

In the second iteration of the small security rebalancing, the weight of the second largest small security, already adjusted in the first iteration, will be scaled upwards by a factor which sets it equal to the average NDX weight of 1.0%. The weights of each of the smaller remaining small securities will be scaled up by this same factor reduced in relation to each security's relative ranking among the small securities such that, once again, the smaller the security in the ranking, the less its weight will be scaled upward. Additional iterations will be performed until the accumulated increase in weight among the small securities equals the aggregate weight reduction among the large securities that resulted from the rebalancing in accordance with the two weight distribution conditions discussed above.

Finally, to complete the rebalancing process, once the final weighting percentages for each NDX security have been set, the NDX Shares will be determined anew based upon the last sale prices and aggregate capitalization of the NDX at the close of trading on the last calendar day in February, May, August and November. Changes to the NDX Shares will be made effective after the close of trading on the third Friday in March, June, September and December, and an adjustment to the divisor is made to ensure continuity of the NDX. Ordinarily, new rebalanced NDX Shares will be determined by applying the above procedures to the current NDX Shares. However, Nasdaq, Inc. may, from time to time, determine rebalanced weights, if necessary, by applying the above procedure to the actual current market capitalization of the NDX components. In such instances, Nasdaq, Inc. would announce the different basis for rebalancing prior to its implementation.

During the quarterly rebalancing, data is cutoff as of the previous month end and no changes are made to the NDX from that cutoff until the quarterly index share change effective date, except in the case of changes due to corporate actions with an ex-date.

Adjustments for Corporate Actions

Changes in the price and/or NDX Shares driven by corporate events such as stock dividends, splits, and certain spin-offs and rights issuances will be adjusted on the ex-date. If the change in total shares outstanding arising from other corporate actions is greater than or equal to 10.0%, the change will be made as soon as practicable. Otherwise, if the change in total shares outstanding is less than 10.0%, then all such changes are accumulated and made effective at one time on a quarterly basis after the close of trading on the third Friday in each of March, June, September, and December. The NDX Shares are derived from the security's total shares outstanding. The NDX Shares are adjusted by the same percentage amount by which the total shares outstanding have changed.

The VanEck^® Semiconductor ETF

The SMH is an exchange-traded fund that trades on the NYSE Arca, Inc. under the ticker symbol "SMH." The SMH seeks to replicate as closely as possible, before fees and expenses, the price and yield performance of the MVIS^® US Listed Semiconductor 25 Index ("MVSMH"). For more information about the MVSMH, please see "The MVIS^® US Listed Semiconductor 25 Index" below.

The SMH, using a "passive" or indexing investment approach, attempts to approximate the investment performance of the MVSMH by investing in a portfolio of securities that generally replicates the MVSMH.

The SMH's return may not match the return of the MVSMH for a number of reasons. For example, the SMH incurs a number of operating expenses not applicable to the MVSMH and incurs costs associated with buying and selling securities, especially when rebalancing the SMH's securities holdings to reflect changes in the composition of the MVSMH, which are not factored into the return of the MVSMH. Transaction costs, including brokerage costs, will decrease the SMH's net asset value to the extent not offset by the transaction fee payable by an authorized participant. Market disruptions and regulatory restrictions could have an adverse effect on the SMH's ability to adjust its exposure to the required levels in order to track the MVSMH. Errors in the MVSMH data, the MVSMH computations and/or the construction of the MVSMH in accordance with its methodology may occur from time to time and may not be identified and corrected by the MVSMH provider for a period of time or at all, which may have an adverse impact on the SMH and its shareholders. In addition, the SMH may not invest in certain securities included in the MVSMH, or invest in them in the exact proportions in which they are represented in the MVSMH. The SMH's performance may also deviate from the return of the MVSMH due to legal restrictions or limitations imposed by the governments of certain countries, certain listing standards of the SMH's listing exchange, a lack of liquidity on stock exchanges in which the securities trade, potential adverse tax consequences or other regulatory reasons (such as diversification requirements). The SMH may value certain of its investments and/or other assets based on fair value prices. To the extent the SMH calculates its net asset value based on fair value prices and the value of the MVSMH is based on securities' closing prices (i.e., the value of the MVSMH is not based on fair value prices), the SMH's ability to track the MVSMH may be adversely affected. In addition, any issues the SMH encounters with regard to currency convertibility (including the cost of borrowing funds, if any) and repatriation may also increase tracking risk. In light of the factors discussed above, the SMH's return may deviate significantly from the return of the MVSMH. Changes to the composition of the MVSMH in connection with a rebalancing or reconstitution of the MVSMH may cause the SMH to experience increased volatility, during which time the SMH's index tracking risk may be heightened.

The MVIS^® US Listed Semiconductor 25 Index

All information contained in this pricing supplement regarding the MVSMH, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, MV Index Solutions GmbH ("MVIS"). The MVSMH was developed by MVIS and is maintained and published by MVIS. The MVSMH is calculated by Solactive AG. MVIS has no obligation to continue to publish, and may discontinue the publication of, the MVSMH.

The MVSMH is reported by Bloomberg L.P. under the ticker symbol "MVSMH."

The MVSMH is designed to track the performance of the largest and most liquid U.S.-listed companies that derive at least 50% (25% for current components) of their revenues from semiconductors. This includes companies engaged primarily in the production of semiconductors and semiconductor equipment. The MVSMH was launched on August 12, 2011 with a base index value of 1,000 as of September 29, 2000.

Index Composition and Maintenance

The Index Universe

The index universe includes only common stocks and stocks with similar characteristics from financial markets that are freely investable for foreign investors and that provide real-time and historical component and currency pricing. Limited partnerships are excluded. Companies from financial markets that are not freely investable for foreign investors or that do not provide real-time and historical component and currency pricing may still be eligible if they have a listing on an eligible exchange and if they meet all the size and liquidity requirements on that exchange.

Only stocks that have a full market capitalization exceeding US$50 million are eligible for the index universe.

Investable Index Universe

Companies with a free-float (or shares available to foreign investors) of less than 5% for existing index components or less than 10% for new components are ineligible for inclusion.

In addition to the above, stocks that are currently not in the MVSMH must meet the following size and liquidity requirements:

•a full market capitalization exceeding US$150 million;

•a three-month average-daily-trading volume of at least US$1 million at the current review and also at the previous two reviews; and

•at least 250,000 shares traded per month over the last six months at the current review and also at the previous two reviews.

For stocks already in the MVSMH the following applies:

Enhanced Return Notes Linked to the Least Performing of the Invesco QQQ Trust^SM, Series 1, the VanEck^® Semiconductor ETF and the iShares^® Expanded Tech-Software Sector ETF

•a full market capitalization exceeding US$75 million; and

•a three-month average-daily-trading volume of at least US$0.2 million in at least two of the latest three quarters (current review and also at previous two reviews)

•In addition, a three-month average-daily-trading volume of at least US$0.6 million at current review or at one of the previous two reviews; or

•at least 200,000 shares traded per month over the last six months at the current review or at one of the previous two reviews.

In case the number of investable stocks drops below the minimum component number for the respective index, current components remain investable.

Only one share line of each company is eligible. In case more than one share line fulfills the above size and liquidity rules, only the largest share line by free-float market capitalization is eligible. MVIS can, in exceptional cases (e.g., significantly higher liquidity), decide for a different share line.

In case the free-float market capitalization of a non-component share line:

•exceeds the free-float market capitalization of a share line of the same company which is an index component by at least 25%; and

•fulfills all size and liquidity eligibility criteria for non-components,

•the current component share line will be replaced by the larger one. MVIS can, in exceptional cases (e.g., significantly higher liquidity), decide to keep the current share line instead.

Index Constituent Selection

The MVSMH is reviewed on a semi-annual basis in March and September.

The target coverage of the MVSMH is 25 companies from the investable universe. MVSMH constituents are selected using the following procedure:

(1)The largest 50 stocks (by full market capitalization) from the investable universe qualify.

(2)The 50 stocks are ranked in two different ways - by free-float market capitalization in descending order (the largest company receives rank "1") and then by three-month average-daily-trading volume in descending order (the most liquid company receives rank "1"). These two ranks are added up.

(3)The 50 stocks are then ranked by the sum of their two ranks in Step 2 in ascending order. If two companies have the same sum of ranks, the larger company is placed on top.

a.Initially, the highest ranked 25 companies made up the MVSMH.

b.On-going, a 10-40 buffer is applied: the highest ranked 10 companies qualify. The remaining 15 companies are selected from the highest ranked remaining current MVSMH components ranked between 11 and 40. If the number of selected companies is still below 25, then the highest ranked remaining stocks are selected until 25 companies have been selected.

Review Schedule

The reviews for the MVSMH are based on the closing data on the last business day in February and August. If a company does not trade on the last business day in February or August, the last available price for this company will be used.

The underlying index data (e.g., new number of shares, new free-float factors and new weighting cap factors) is announced on the second Friday in March or September. The weighting cap factors are based on closing data of the Wednesday prior to the second Friday in March or September. Changes to the MVSMH are implemented and based on the closing prices of the third Friday in March or September. If the third Friday is not a business day, then the review will take place on the last business day before the third Friday. If a constituent of the MVSMH does not trade on the third Friday in March or September, then the last available price for that index constituent will be used. Changes become effective on the next business day. The component changes to the MVSMH are announced on the second Friday in March or September.

Ongoing Maintenance

In addition to the periodic reviews, the MVSMH is continually reviewed for corporate events (e.g., mergers, takeovers, spin-offs, delistings and bankruptcies) that affect the MVSMH components.

Deletions. For all corporate events that result in a stock deletion from the MVSMH, the deleted stock will be replaced with the highest ranked non-component on the most recent selection list immediately only if the number of components in the MVSMH would drop below 20. The replacement stock will be added at the same weight as the deleted stock. Only in case the number of components drop below its minimum due to a merger of two or more index components, the replacement stock will be added with its free-float market capitalization, weighted with the capping factor of the uncapped components in the small-weight group of the weighting scheme. In all other cases (i.e., there is not replacement), the additional weight resulting from the deletion will be redistributed proportionally across all other components of the MVSMH.

Changes to Free-Float Factor and Number of Shares. Changes to the number of shares or the free-float factors due to corporate actions like stock dividends, splits, rights issues, etc. are implemented immediately and will be effective the next trading day (i.e., the ex-date). Simple share/float changes are implemented after a 3-day notice period.

Initial Public Offerings (IPOs) and Spin-Offs. An IPO stock is eligible for fast-track addition to the index universe for the MVSMH once; either at the next

Enhanced Return Notes Linked to the Least Performing of the Invesco QQQ Trust^SM, Series 1, the VanEck^® Semiconductor ETF and the iShares^® Expanded Tech-Software Sector ETF

semi-annual review if it has been trading since at least the last trading day of the month prior to the review snapshot dates (i.e., the last trading day in February or August) or else at the then-following semi-annual review. In order to be added to the MVSMH the IPO stock has to meet the size and liquidity requirements:

•the IPO must have a full market capitalization exceeding US$150 million;

•the IPO must have a free-float factor of at least 10%;

•the IPO must have an average-daily-trading volume of at least US$1 million; and

•the IPO must have traded at least 250,000 shares per month (or per 22 days).

This rule is applicable for newly spun-off companies as well.

Changes due to Mergers & Takeovers. A merger or takeover is deemed successful if it has been declared wholly unconditional and has received approval of all regulatory agencies with jurisdiction over the transaction. The result of a merger or takeover is typically one surviving stock and one or more non-surviving stocks that may not necessarily be de-listed from the respective trading system(s).

If a MVSMH component merges with or takes over another MVSMH component: The surviving stock remains in the MVSMH and the other stock is deleted immediately from the MVSMH. Its shares and float are adjusted according to the terms of the merger/takeover. The index market capitalization of the merged company corresponds to the market capitalization of the two separate companies.

If a MVSMH component merges with or takes over a non-MVSMH component: If the surviving stock meets the MVSMH requirements, then it remains in the MVSMH and its shares (if the share change is greater than 10%) and float are adjusted according to the terms of the merger/takeover. If the surviving stock does not meet the MVSMH requirements, then it is deleted immediately from the MVSMH.

If a non-MVSMH component merges with or takes over a MVSMH component: If the surviving stock meets the MVSMH requirements, then it will be added to the MVSMH (shares (if the share change is greater than 10%) and float adjusted according to the terms of the merger/takeover) and will replace the current MVSMH component. If the surviving stock does not meet the MVSMH requirements, then it will not be added to the MVSMH and the current MVSMH component is deleted immediately from the MVSMH.

Changes due to Spin-Offs. Each spin-off stock is immediately added to the MVSMH for at least two trading days. If a spin-off company does not qualify for the MVSMH, it will be deleted based on its closing price. Shares and floats of the surviving companies are adjusted according to the terms of the spin-off. In case the number of MVSMH components drops below the minimum component number and no non-component stock is eligible as a replacement, the determination of the addition is subject to MVIS's decision.

Index Calculation

The value of the MVSMH is calculated using the Laspeyres' formula, rounded to two decimal places, with stock prices converted to U.S. dollars:

where (for all stocks (i) in the MVSMH):

·p_i = stock price (rounded to four decimal places);

·q_i = number of shares;

·ff_i = free-float factor (rounded to two decimal places);

·fx_i = exchange rate (local currency to U.S. Dollar) (rounded to 12 decimal places);

·cf_i = sector-weighting cap factor (if applicable, otherwise set to 1) (rounded to 16 decimal places);

·M = free-float market capitalization of the MVSMH; and

·D = divisor (rounded to six decimal places).

Free-Float

The MVSMH is free-float adjusted - that is, the number of shares outstanding is reduced to exclude closely held shares (amount larger than 5% of the company's full market capitalization) from the index calculation. At times, other adjustments are made to the share count to reflect foreign ownership limits. These are combined with the block-ownership adjustments into a single factor. To avoid unwanted double counting, either the block-ownership adjustment or the restricted stocks adjustment is applied, whichever produces the higher result. Free-float factors are reviewed quarterly.

Company-Weighting Cap Factors

Companies in the MVSMH are weighted according to their free-float market capitalization, as modified by the company-weighting cap factors. The MVSMH used the company-weighting cap factors to ensure diversification to avoid overweighting. The company-weighting cap factors are reviewed quarterly and applied, if necessary. The following weighting scheme applies to the MVSMH:

(1)All MVSMH components are weighted by their free-float market capitalization.

(2)All companies exceeding 4.5% but at least the largest five and at the maximum the largest 10 companies are grouped together (so called

Enhanced Return Notes Linked to the Least Performing of the Invesco QQQ Trust^SM, Series 1, the VanEck^® Semiconductor ETF and the iShares^® Expanded Tech-Software Sector ETF

"Large-Weights"). All other companies are grouped together as well (so called "Small-Weights").

(3)The aggregated weighting of the Large-Weights is capped at 50%:

a.Large-Weights: If the aggregated weighting of all companies in Large-Weight exceeds 50%, then a capping factor is calculated to bring the weighting down to 50%; at the same time, a second capping factor for the Small-Weights is calculated to increase the aggregated weight to 50%. These two factors are then applied to all companies in the Large-Weights or the Small-Weights respectively.

b.Large-Weights: The maximum weight for any single stock is 20% and the minimum weighting is 5%. If a stock is above the maximum or below the minimum weight, then the weight will be reduced to the maximum weight or increased to the minimum weight and the excess weight will be re-distributed proportionally across all other remaining MVSMH constituents in the Large-Weights.

c.Small-Weights: The maximum weight for any single stock is 4.5%. If a stock is above the maximum weight, then the weight will be reduced to the maximum weight and the excess weight will be re-distributed proportionally across all other remaining MVSMH constituents in the Small-Weights.

Divisor Adjustments

Index maintenance (reflecting changes in, e.g., shares outstanding, capital actions, addition or deletion of stocks to the MVSMH) should not change the level of the MVSMH. This is accomplished with an adjustment to the divisor. Any change to the stocks in the MVSMH that alters the total market value of the MVSMH while holding stock prices constant will require a divisor adjustment.

where ∆MC is the difference between closing market capitalization and adjusted closing market capitalization of the MVSMH.

Data Correction

Incorrect or missing input data will be corrected immediately.

Corporate Action Related Adjustments

Corporate actions range widely from routine share issuances or buy backs to unusual events like spin-offs or mergers. These are listed on the table below with notes about the necessary changes and whether the divisor will be adjusted. Implementation takes place on the ex-date.

Enhanced Return Notes Linked to the Least Performing of the Invesco QQQ Trust^SM, Series 1, the VanEck^® Semiconductor ETF and the iShares^® Expanded Tech-Software Sector ETF

With corporate actions where cash dividends or other corporate assets are distributed to shareholders, the price of the stock will drop on the ex-dividend day (the first day when a new shareholder is eligible to receive the distribution). The effect of the divisor adjustment is to prevent this price drop from causing a corresponding drop in the MVSMH.

Corporate actions are announced at least four days prior to implementation.

The iShares^® Expanded Tech-Software Sector ETF

The shares of the IGV are issued by iShares® Trust, a registered investment company. The IGV seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P North American Expanded Technology Software IndexTM, its underlying index. The IGV is composed of North American equities in the software industry and select North American equities from interactive home entertainment and interactive media and services industries. The IGV typically earns income dividends from securities included in the IGV. These amounts, net of expenses and taxes (if applicable), are passed along to the IGV's shareholders as "ordinary income." In addition, the IGV realizes capital gains or losses whenever it sells securities. Net long-term capital gains are distributed to shareholders as "capital gain distributions." However, because the Notes are linked only to the share price of the IGV, you will not be entitled to receive income, dividend, or capital gain distributions from the IGV or any equivalent payments. BlackRock Fund Advisors ("BFA") is the investment adviser to the IGV. The shares of the IGV trade on the NYSE Arca under the ticker symbol "IGV."

As investment adviser, BFA has overall responsibility for the general management and administration of the IGV. For its investment advisory services to the IGV, BFA is paid a management fee correlating to the IGV's allocable portion of an aggregate management fee calculated based on the aggregate average daily net assets of a group of iShares funds, as follows: 0.4800% per annum of the aggregate net assets less than or equal to $10.0 billion, plus 0.4300% per annum of the aggregate net assets over $10.0 billion, up to and including $20.0 billion, plus 0.3800% per annum of the aggregate net assets over $20.0 billion up to and including $30.0 billion, plus 0.3420% per annum of the aggregate net assets over $30.0 billion, up to and including $40.0 billion, plus 0.3078% per annum of the aggregate net assets in excess of $40.0 billion.

The shares of the IGV are registered under the Securities Exchange Act of 1934, as amended. Accordingly, information filed with the SEC relating to the IGV, including its periodic financial reports, may be found on the SEC website.

S&P North American Expanded Technology Software IndexTM

The underlying index is a capped modified market capitalization-based index that measures the performance of U.S.-traded stocks from the software industry and select companies from the interactive home entertainment and interactive media and services industries in the U.S. and Canada, as determined by S&P Dow Jones Indices. The underlying index is reported by Bloomberg L.P. under the ticker symbol "SPNASEUP."

Underlying Index Composition and Construction

The underlying index is comprised of the constituents of the S&P North American Technology Software IndexTM (the "Parent Index") and any eligible "Supplementary Stocks" (as defined below). S&P Dow Jones Indices assigns constituents to the Parent Index based on the constituent's classification under the Global Industry Classification Standard ("GICS®"). The Parent Index is a capped modified market capitalization-based index that measures the performance of the securities classified under the GICS® application software and systems software sub-industries.

A "Supplementary Stock" is a stock that is not included in the list of eligible GICS® classifications but otherwise meets all eligibility criteria of the Parent Index. Although a Supplementary Stock is not included in the Parent Index, it will be included in the underlying index.

Additions and Deletions

Additions to the Parent Index are added to the underlying index simultaneously. With the exception of the Supplementary Stocks, constituents removed from the Parent Index are removed from the underlying index simultaneously. If a Supplementary Stock is removed from the S&P TMI, it is removed from the underlying index simultaneously.

Constituent Weightings

At each quarterly rebalancing the underlying index is weighted by float-adjusted market capitalization, subject to the following diversification requirements:

•The weight of a single company cannot exceed 8.5%.

•The aggregate weight of the companies in the underlying index with a weight greater than 4.5% cannot exceed 45%.

Underlying Index Maintenance

All underlying index adjustments and corporate action treatments follow the Parent Index.

Parent Index Composition and Construction

Index Universe:

To be eligible for inclusion in the Parent Index, the company must be a member of either the S&P Total Market Index (the "S&P TMI") or the S&P/TSX Composite Index (the "S&P TSX").

Enhanced Return Notes Linked to the Least Performing of the Invesco QQQ Trust^SM, Series 1, the VanEck^® Semiconductor ETF and the iShares^® Expanded Tech-Software Sector ETF

•The S&P TMI offers broad market exposure to companies of all market capitalizations, including all U.S. common equities with a primary listing on the New York Stock Exchange ("NYSE"), NYSE Arca, NYSE American, Nasdaq Global Select Market, Nasdaq Select Market, Nasdaq Capital Market, Cboe BZX, Cboe BYX, Cboe EDGA or Cboe EDGX exchanges. Only U.S. companies are eligible for inclusion in the S&P TMI.

•The S&P TSX is a broad market measure for the Canadian equity markets and includes common stocks and income trust units. Canadian companies included in the S&P TSX must meet minimum market capitalization requirements based on their volume weighted average prices on the Toronto Stock Exchange.

Eligibility Criteria as of Each Rebalancing Include:

•Market Capitalization. The company must have full market capitalization above its sector capitalization cutoff of US$ 1.4 billion as of the rebalancing reference date to be added to the Parent Index. This cutoff is subject to change depending on market requirements. Current constituents of the Parent Index with a full market capitalization below 50% of their sector capitalization cutoff are removed.

•Liquidity. Stocks must have a liquidity ratio greater than 30%. The liquidity ratio is defined as the annualized dollar value traded over the previous six months divided by the average full market capitalization over the previous six months. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have six months of trading history. If a stock has been trading for fewer than six calendar months, the stock's average daily share volume for its entire trading history is used to calculate its liquidity ratio. Current constituents of the Parent Index with a liquidity ratio less than 15%, based on annualized dollar value traded for the prior six calendar months, are removed.

•Public Float. Companies with a public float below 20% are not eligible (or 10% for current constituents of the Parent Index).

•Exchange Listing. The company's stock must trade on the NYSE, Nasdaq Global Select Market and CBOE. Only actual common shares outstanding are eligible for inclusion. Canadian companies with common shares listed on the above exchanges are eligible for inclusion, but American Depositary Receipts are not eligible.

•GICS Sector Classification. Companies classified as part of one of the following GICS® classifications are eligible: application software sub-industry or systems software sub-industry.

•Minimum Constituent Count. At each quarterly rebalancing, if the constituent count is less than 22 after applying the rules set forth in the eligibility criteria, the market capitalization requirement is relaxed so that the next largest non-constituent in the eligible universe is added until the constituent count reaches 22. A buffer is applied such that a stock being added must have a float-adjusted market capitalization greater than 1.2 times (or 20% higher than) the stock it is replacing. The buffer is evaluated on each stock addition relative to the current stock it is replacing. For example, the largest non-index stock by float-adjusted market capitalization is evaluated against the smallest index constituent, the second largest non-index stock is evaluated against the second smallest index constituent, etc. This process is repeated until no stock additions exceed the buffer.

•Multiple Classes of Stock. All publicly listed multiple share class lines are eligible for inclusion in the Parent Index, subject to meeting the eligibility criteria.

Constituent Weightings

The Parent Index is weighted by float-adjusted market capitalization, subject to the diversification rules outlined below. The weight removed from a company due to the diversification rules is proportionally redistributed among all other uncapped index constituents. The weight of a particular company in the Parent Index is capped at 8.5%.

The following procedure is used to ensure that no index constituent weighting exceeds the pre-defined maximum weight as of the rebalancing reference date:

1.The reference date for pricing is the Thursday prior to the second Friday of March, June, September and December.

2.With prices reflected on the pricing reference date, and membership, shares outstanding and investable weight factors as of the rebalancing effective date, each company is weighted by float-adjusted market capitalization.

3.If any company's weight exceeds 8.5%, that company's weight is capped at the maximum level and all excess weight is proportionally redistributed to all uncapped companies within the Parent Index. If, after this redistribution, any company breaches the weight cap, the process is repeated iteratively until no company breaches the company capping rule.

4.Then, the aggregate weight of the companies in the Parent Index with a weight greater than 4.5% cannot exceed 45%. These caps are set to allow for a buffer below the respective 5% and 50% limits.

5.If the rule in step 4 is breached, all the companies are ranked in descending order of their weights and the company with the lowest weight that causes the 45% limit to be breached is reduced either until the rule in step 4 is satisfied or its individual weight falls to 4.5%.

6.This excess weight is proportionally redistributed to all companies with weights below 4.5%. Any stock that receives weight cannot breach the

4.5% cap. This process is repeated iteratively until step 4 is satisfied or until all stocks are greater than or equal to 4.5%.

Parent Index Calculation

The Parent Index is a capped modified market capitalization-weighted index where index constituents have a defined weight in the Parent Index. The index value of the Parent Index is simply the market value of the Parent Index divided by the index divisor:

Index Market Value = × Sharesi × IWFi × AWFi

Where:

Pi = the price of stock i;

Sharesi = the outstanding shares of stock i;

IWFi = the float factor of stock i (as defined below);

AWFi = the adjustment factor of stock i assigned at each index rebalancing date, t, which adjusts the market capitalization for all

index constituents to achieve the user-defined weight, while maintaining the total market value of the overall index

The AWF for each index constituent, i, at rebalancing date, t, is calculated as:

Where:

Wi,t = the uncapped weight of stock i on rebalancing date t based on the float-adjusted market capitalization of all index

constituents;

CWi,t = the capped weight of stock i on rebalancing date t as determined by the capping rules described under "- Constituent Weighting" above.

The Parent Index is calculated in U.S. dollars.

Float Adjustment. Under float adjustment, the share counts used in calculating the Parent Index reflect only those shares available to investors rather than a company's total outstanding shares. Float adjustment excludes shares that are held by other publicly traded companies, government agencies, or certain types of strategic shareholders.

For each component, S&P Dow Jones Indices calculates an Investable Weight Factor ("IWF"), which represents the portion of the total shares outstanding that are considered part of the public float for purposes of the Parent Index.

The purpose of the divisor is to maintain continuity of the level of the Parent Index following the implementation of corporate actions, index rebalancing events, or other non-market driven actions. To assure that the Parent Index's value, or level, does not change when stocks are added or deleted, the divisor is adjusted to offset the change in market value of the Parent Index. Thus, the divisor plays a critical role in the Parent Index's ability to provide a continuous measure of market valuation when faced with changes to the stocks included in the Parent Index. In a similar manner, some corporate actions that cause changes in the market value of the stocks in the Parent Index should not be reflected in the level of the Parent Index. Adjustments are made to the divisor to eliminate the impact of these corporate actions on the Parent Index's value.

Parent Index Maintenance

Rebalancing

Index membership is reviewed semi-annually, effective after the market close on the third Friday of June and December, respectively. The reconstitution reference date is after the market close of the last trading date of the previous month.

Weight capping is applied quarterly, after the market close on the third Friday of March, June, September, and December. Constituents' index shares are calculated using closing prices on the Thursday prior to the second Friday of the rebalancing month as the reference price. Index shares are calculated and assigned to each stock to arrive at the weights determined on the reference date. Since index shares are assigned in advance, the actual

Enhanced Return Notes Linked to the Least Performing of the Invesco QQQ Trust^SM, Series 1, the VanEck^® Semiconductor ETF and the iShares^® Expanded Tech-Software Sector ETF

weight of each stock at the rebalancing differs from these weights due to market movements.

Additions

Except for spin-offs, companies can only be added to the Parent Index at the time of the semi-annual reconstitution. All companies not already in the Parent Index, which meet the eligibility criteria on the reconstitution reference date, are added to the Parent Index prior to the open of trading on the reconstitution date.

Deletions

Between rebalancings, a company can be deleted from the Parent Index due to corporate events such as mergers, acquisitions, takeovers or delistings. Deleted constituents are not replaced. In the case of GICS® changes, where a company does not belong to a qualifying sector after a classification change, it is removed from the Parent Index at the next reconstitution.

Spin-offs

The spin-off is added to the Parent Index at a zero price after the market close of the day before the ex-date (with no divisor adjustment). If the spin-off remains in the underlying universe (the S&P TMI or the S&P TSX), both the parent and the spin-off will remain in the Parent Index until the next index reconstitution, at which time each will be evaluated for continued membership. If the spin-off does not remain in the underlying universe, the spin-off is then removed from the Parent Index after the close of its first day of regular way trading (with a divisor adjustment).

Other Corporate Actions

The Parent Index will be adjusted for other corporate actions, such as changes in shares outstanding, stock splits or reverse splits, special dividends, right offerings and mergers and acquisitions.

Other Adjustments

In cases where there is no achievable market price for a stock being deleted, it can be removed at a zero or minimal price at the Index Committee's (defined below) discretion, in recognition of the constraints faced by investors in trading bankrupt or suspended stocks.

Index Governance

An S&P Dow Jones Indices Index Committee ("Index Committee") maintains the Parent Index and underlying index. All members are full-time professional members of S&P Dow Jones Indices' staff. At each meeting, the Index Committee reviews pending corporate actions that may affect index constituents, statistics comparing the composition of the indices to the market, companies that are being considered as candidates for addition to an index, and any significant market events. In addition, the Index Committee may revise index policy covering rules for selecting companies, treatment of dividends, share counts or other matters.

S&P Dow Jones Indices considers information about changes to its U.S. indices and related matters to be potentially market moving and material. Therefore, all Index Committee discussions are confidential.

S&P Dow Jones Indices' Index Committees reserve the right to make exceptions when applying the methodology if the need arises. In any scenario where the treatment differs from the general rules stated in this document or supplemental documents, clients will receive sufficient notice, whenever possible.

In addition to the daily governance of indices and maintenance of index methodologies, at least once within any 12-month period, the Index Committee reviews the methodology to ensure the indices continue to achieve the stated objectives, and that the data and methodology remain effective. In certain instances, S&P Dow Jones Indices may publish a consultation inviting comments from external parties.

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 $999.70 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.

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 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 single financial contracts with respect to the Underlyings. This discussion assumes that the Notes constitute single financial contracts with respect to the Underlyings for U.S. federal income tax purposes. If the Notes did not constitute 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

Upon receipt of a cash payment at maturity or upon a sale or exchange 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 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.

Possible Application of Section 1260 of the Code. Since the Underlyings are the type of financial assets 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

Enhanced Return Notes Linked to the Least Performing of the Invesco QQQ Trust^SM, Series 1, the VanEck^® Semiconductor ETF and the iShares^® Expanded Tech-Software Sector ETF

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 or settlement (assuming such income accrued at a constant rate equal to the applicable federal rate as of the date of sale, exchange 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 or exchange 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 or exchange of the Notes generally would be treated as ordinary income, and any loss realized at maturity or upon a sale or exchange 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.

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 or exchange of the Notes should be treated as ordinary gain or loss.

Non-U.S. Holders

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 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 or exchange 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, 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 gain realized on the settlement at maturity, or upon sale or exchange 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 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, tax will be withheld at the applicable statutory rate. As discussed above, the IRS has indicated in the Notice that it is considering whether income in respect of instruments such as the Notes should be subject to withholding tax. 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.
