Maturity:

Approximately 2.5 years, unless redeemed earlier at our discretion.

Payment at maturity:

If the securities have not previously been redeemed, investors will receive on the maturity date a payment at maturity determined as follows:

If the final share price is greater than or equal to the downside threshold level, investors will receive the stated principal amount and the contingent quarterly coupon with respect to the final observation date.

If the final share price is less than the downside threshold level, investors will receive a payment at maturity that is less than 75% of the stated principal amount of the securities and could be zero. Accordingly, investors in the securities must be willing to accept the risk of losing their entire initial investment.

Contingent quarterly coupon:

A contingent coupon of at least $25.375 per quarter per security (equal to a rate of at least 2.5375% per quarter or at least 10.15% per annum) will be paid on the securities on each coupon payment date but only if the observation closing price of the underlying stock is at or above the coupon barrier level on the related observation date. The actual contingent quarterly coupon will be determined on the pricing date.

If, on any observation date, the observation closing price of the underlying stock is less than the coupon barrier level, we will pay no coupon for the applicable quarterly period.

Early redemption:

Beginning on July 23, 2026, on any redemption date, we have the right to redeem all (but not less than all) of the securities for a redemption payment equal to the stated principal amount plus any contingent quarterly coupon otherwise due with respect to the relevant observation date. An early redemption of the securities will not automatically occur based on the performance of the underlying stock. We will give notice to the trustee at least five business days but not more than 60 calendar days before the applicable redemption date. No further payments will be made on the securities once they have been redeemed.

Scenario 1: The securities are redeemed prior to maturity.

This scenario assumes that we redeem the securities at our discretion prior to the maturity date on one of the quarterly redemption dates, starting on July 23, 2026, for a redemption payment equal to the stated principal amount plus any contingent quarterly coupon otherwise due with respect to the relevant observation date. Prior to the early redemption, the observation closing price of the underlying stock is at or above the coupon barrier level on some or all of the quarterly observation dates. In this scenario, investors receive the contingent quarterly coupon with respect to each such observation date, but not for the quarterly periods for which the observation closing price of the underlying stock is below the coupon barrier level on the related observation date. No further payments will be made on the securities once they have been redeemed.

Scenario 2: The securities are not redeemed prior to maturity, and investors receive principal back at maturity.

This scenario assumes that we do not redeem the securities on any of the quarterly redemption dates, and, as a result, investors hold the securities to maturity. During the term of the securities, the observation closing price of the underlying stock is at or above the coupon barrier level on some quarterly observation dates and below the coupon barrier level on the others. Consequently, investors receive the contingent quarterly coupon for the quarterly periods for which the observation closing price of the underlying stock is at or above the coupon barrier level on the related observation date, but not for the quarterly periods for which the observation closing price of the underlying stock is below the coupon barrier level on the related observation date. On the final observation date, the final share price of the underlying stock is at or above the downside threshold level. Therefore, at maturity investors will receive the stated principal amount and the contingent quarterly coupon with respect to the final observation date.

Scenario 3: The securities are not redeemed prior to maturity, and investors suffer a substantial loss of principal at maturity.

This scenario assumes that we do not redeem the securities on any of the quarterly redemption dates, and, as a result, investors hold the securities to maturity. During the term of the securities, the observation closing price of the underlying stock is below the coupon barrier level on all or nearly all of the quarterly observation dates. In this scenario, investors do not receive any contingent quarterly coupons, or receive contingent quarterly coupons for only a limited number of coupon payment dates. On the final observation date, the final share price of the underlying stock is below the downside threshold level. Therefore, investors receive an amount equal to the stated principal amount multiplied by the share performance factor at maturity. Under these circumstances, the payment at maturity will be less than 75% of the stated principal amount and could be zero. No coupon will be paid at maturity in this scenario.

Hypothetical Initial Share Price:

Contingent Quarterly Coupon:

At least $25.375 per security (equal to a rate of at least 2.5375% per quarter or at least 10.15% per annum). The actual contingent quarterly coupon will be determined on the pricing date.

A contingent quarterly coupon is paid on each coupon payment date but only if the observation closing price of the underlying stock is at or above the coupon barrier level on the related observation date.

Call Feature:

Beginning on July 23, 2026, on any redemption date, we have the right to redeem all (but not less than all) of the securities for a redemption payment equal to the stated principal amount plus any contingent quarterly coupon otherwise due with respect to the relevant observation date.

Denominations:

The securities will be issued in minimum denominations of $1,000 and whole multiples of $1,000 in excess thereof.

Calculation agent:

BofAS, an affiliate of BofA Finance.

Events of default and acceleration:

If an event of default, as defined in the senior indenture relating to the securities and in the section entitled "Description of Debt Securities of BofA Finance LLC-Events of Default and Rights of Acceleration" on page 51 of the accompanying prospectus, with respect to the securities occurs and is continuing, the amount payable to a holder of the securities upon any acceleration permitted under the senior indenture will be equal to the amount described under the caption "Payment at maturity" above, calculated as though the date of acceleration were the maturity date of the securities and as though the final observation date were the third trading day prior to the date of acceleration. We will also determine whether the final contingent quarterly coupon is payable based upon the observation closing price of the underlying stock on the deemed final observation date; any such final contingent quarterly coupon will be prorated by the calculation agent to reflect the length of the final contingent quarterly coupon period. In case of a default in the payment of the securities, whether at their maturity or upon acceleration, the securities will not bear a default interest rate.

Additional Information:

Tax considerations:

The following summary of the material U.S. federal income and estate tax considerations of the acquisition, ownership, and disposition of the securities 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 securities 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 securities upon original issuance and will hold the securities 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 securities, 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 securities, we intend to treat the securities for all tax purposes as contingent income-bearing single financial contracts with respect to the underlying stock and under the terms of the securities, we and every investor in the securities agree, in the absence of an administrative determination or judicial ruling to the contrary, to treat the securities in accordance with such characterization. In the opinion of our counsel, Sidley Austin LLP, it is reasonable to treat the securities as contingent income-bearing single financial contracts with respect to the underlying stock. This discussion assumes that the securities constitute contingent income-bearing single financial contracts with respect to the underlying stock for U.S. federal income tax purposes. If the securities did not constitute contingent income-bearing single financial contracts, the tax consequences described below would be materially different.

This characterization of the securities is not binding on the IRS or the courts. No statutory, judicial, or administrative authority directly addresses the characterization of the securities 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 securities 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 securities, 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 securities.

We will not attempt to ascertain whether the issuer of the underlying stock 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 the underlying stock were so treated, certain adverse U.S. federal income tax consequences could possibly apply to a holder of the securities. You should refer to information filed with the SEC by the issuer of the underlying stock and consult your tax advisor regarding the possible consequences to you, if any, if the issuer of underlying stock is or becomes a PFIC or is or becomes a United States real property holding corporation.

U.S. Holders

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

Upon receipt of a cash payment at maturity or upon a sale, exchange, or redemption of the securities prior to maturity, a U.S. Holder generally will recognize capital gain or loss equal to the difference between the amount realized (other than amounts representing any contingent quarterly coupon, which would be taxed as described above) and the U.S. Holder's tax basis in the securities. A U.S. Holder's tax basis in the securities will equal the amount paid by that holder to acquire them. This capital gain or loss generally will be long-term capital gain or loss if the U.S. Holder held the securities for more than one year. The deductibility of capital losses is subject to limitations.

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

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

The IRS released Notice 2008-2 (the "Notice"), which sought comments from the public on the taxation of financial instruments currently taxed as "prepaid forward contracts." This Notice addresses instruments such as the securities. According to the Notice, the IRS and Treasury are considering whether a holder of an instrument such as the securities 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 securities, 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 securities.

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

Non-U.S. Holders

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

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

If a Non-U.S. Holder of the securities is engaged in the conduct of a trade or business within the U.S. and if any contingent quarterly coupon and gain realized on the settlement at maturity, or upon sale, exchange, or redemption of the securities, is effectively connected with the conduct of such trade or business (and, if certain tax treaties apply, is attributable to a permanent establishment maintained by the Non-U.S. Holder in the U.S.), the Non-U.S. Holder, although exempt from U.S. federal withholding tax, generally will be subject to U.S. federal income tax on such contingent quarterly coupon and gain on a net income basis in the same manner as if it were a U.S. Holder. Such Non-U.S. Holders should read the material under the heading "-U.S. Holders," for a description of the U.S. federal income tax consequences of acquiring, owning, and disposing of the securities. 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 securities are not delta-one instruments, Non-U.S. Holders should not be subject to withholding on dividend equivalent payments, if any, under the securities. However, it is possible that the securities could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the underlying stock or the securities, and following such occurrence the securities 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 underlying stock or the securities should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the securities 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 securities 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 securities to become subject to withholding tax in addition to the withholding tax described above, tax will be withheld at the applicable statutory rate. Prospective Non-U.S. Holders should consult their own tax advisors regarding the tax consequences of such alternative characterizations.

U.S. Federal Estate Tax. Under current law, while the matter is not entirely clear, individual Non-U.S. Holders, and entities whose property is potentially includible in those individuals' gross estates for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty benefit, a security 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 security.

Backup Withholding and Information Reporting

Please see the discussion under "U.S. Federal Income Tax Considerations - General - Backup Withholding and Information Reporting" in the accompanying prospectus for a description of the applicability of the backup withholding and information reporting rules to payments made on the securities.

Structuring the securities:

The securities are our debt securities, the return on which is linked to the performance of the underlying stock. 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 securities 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 securities, along with the fees and charges associated with market-linked notes, typically results in the initial estimated value of the securities on the pricing date being less than their price to public.

The initial estimated value range of the securities is set forth on the cover page of this pricing supplement. The final pricing supplement will set forth the initial estimated value of the securities as of the pricing date.

In order to meet our payment obligations on the securities, at the time we issue the securities, 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 underlying stock, the tenor of the securities and the hedging arrangements. The economic terms of the securities 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.

For further information, see "Risk Factors" beginning on page 8 above and "Supplemental Use of Proceeds" on page PS-15 of the accompanying product supplement.

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 agent in the distribution of the securities. Accordingly, the offering of the securities 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 securities 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 securities occurs more than one business day from the pricing

date, purchasers who wish to trade the securities 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 securities from us as principal at the public offering price indicated on the cover of this pricing supplement, less the indicated agent's commissions and fees, if any. BofAS will sell the securities 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 securities 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 securities at the same discount. Morgan Stanley Smith Barney LLC ("Morgan Stanley Wealth Management") and its financial advisors will collectively receive from the agent, BofAS, a fixed sales commission for each security they sell, and Morgan Stanley Wealth Management will receive a structuring fee for each security, in each case as specified on the cover page of this document. The costs included in the original issue price of the securities will include a fee paid by BofAS to LFT Securities, LLC, an entity in which an affiliate of BofAS and an affiliate of Morgan Stanley Wealth Management have ownership interests, for providing certain electronic platform services with respect to this offering.

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 securities. 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 securities, BofAS may offer to buy the securities in the secondary market at a price that may exceed the initial estimated value of the securities. Any price offered by BofAS for the securities will be based on then-prevailing market conditions and other considerations, including the performance of the underlying stock and the remaining term of the securities. However, none of us, the guarantor, BofAS or any of our other affiliates is obligated to purchase your securities at any price or at any time, and we cannot assure you that any party will purchase your securities at a price that equals or exceeds the initial estimated value of the securities.

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 securities 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 securities 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 securities other than to Qualified Investors. The expression "Prospectus Regulation" means Regulation (EU) 2017/1129.

PROHIBITION OF SALES TO EEA RETAIL INVESTORS - The securities 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 securities to be offered so as to enable an investor to decide to purchase or subscribe for the securities. Consequently no key information document required by Regulation (EU) No 1286/2014, as amended (the "PRIIPs Regulation") for offering or selling the securities or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the securities or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

PROHIBITION OF SALES TO UNITED KINGDOM RETAIL INVESTORS - The securities are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom. For these purposes: (a) a retail investor means a person who is neither: (i) a professional client as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law in the United Kingdom; nor (ii) a qualified investor as defined in paragraph 15 of Schedule 1 to the Public Offers and Admissions to Trading Regulations 2024 (as may be amended from time to time); and (b) the expression "offer" includes the communication in any form and by any means of sufficient information on the terms of the offer and the securities to be offered so as to enable an investor to decide to purchase or subscribe for the securities . Consequently no key information document required by Regulation (EU) No 1286/2014, as amended (the "PRIIPs Regulation") for offering or selling the securities or otherwise making them available to retail investors in the United Kingdom has been prepared and therefore offering or selling the securities or otherwise making them available to any retail investor in the United Kingdom may be unlawful under the PRIIPs Regulation.
