与纳斯达克-100^®科技行业指数、罗素2000^®指数和标准普尔500^®指数中表现最差的指数挂钩

•2028年9月21日到期的与纳斯达克-100^®科技行业指数、罗素2000^®指数和标准普尔500^®指数中表现最差的指数挂钩的或有收入自动可赎回收益票据（“票据”）于2026年10月16日定价，并将于2026年10月21日发行。

•如果在到期前未被赎回，预计期限约为23个月。

•票据的支付将取决于纳斯达克-100^®科技行业指数、罗素2000^®指数和标准普尔500^®指数（每个均为“标的资产”）的单独表现。

•如果在相关观察日每个标的资产的收盘水平大于或等于其起始值的70.00%，则可获得年化10.50%的或有票面利率（每月0.875%），假设票据未被赎回。

•从2027年10月18日的赎回观察日开始，如果在任何赎回观察日每个标的资产的收盘水平大于或等于其起始值的100.00%，则每月可自动赎回，赎回金额等于本金加上相关或有票面利息。

•假设票据在到期前未被赎回，如果任何标的资产从其起始值下跌超过30%，在到期时您的投资将面临标的资产中最差表现的1:1下行风险，最多可能损失100%的本金；否则，在到期时您将获得本金。在到期时，如果每个标的资产在最终观察日的收盘水平大于或等于其起始值的70.00%，您还将获得最终的或有票面利息。

•票据的所有支付均受BofA Finance LLC（“BofA Finance”或“发行人”）作为票据发行人和美国银行公司（“BAC”或“担保人”）作为票据担保人的信用风险影响。

•票据不会在任何证券交易所上市。

•CUSIP编号09712HRB0。

以定价日为基准，票据的初始估计价值为每1,000.00美元本金价值983.50美元，低于下面列出的公开发行价格。 您的票据在任何时间的实际价值将反映许多因素，无法准确预测。请参阅本定价补充文件第PS-9页开始的“风险因素”以及本定价补充文件第PS-26页的“票据结构”以获取更多信息。

票据与传统债务工具有重要差异。潜在购买者应考虑本定价补充文件第PS-9页开始的“风险因素”、随附产品补充文件第PS-3页、随附招股说明书补充文件第S-7页和随附招股说明书第7页的信息。

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

The initial estimated value of the Notes as of the pricing date is set forth on the cover page of this pricing supplement. For more information about the initial estimated value and the structuring of the Notes, see “Risk Factors” beginning on page PS-9 and “Structuring the Notes” on page PS-26.

假设的收益概况和到期时的支付示例

或有收入自动赎回收益率票据表

下表仅用于说明目的。它假设票据在到期前未被自动赎回，并基于假设值，显示票据的假设收益。该表说明了根据表现最差的标的资产的假设起始值为100、表现最差的标的资产的假设票息障碍值为70、表现最差的标的资产的假设阈值为70、每$1,000.00本金金额的票据的或有票息支付金额为$8.75以及表现最差的标的资产的一系列假设结束值来计算赎回金额和票据的收益。您实际收到的金额和由此产生的收益将取决于标的资产的实际起始值、票息障碍值、阈值、观察值和结束值，票据是否在到期前被自动赎回,以及您是否持有票据至到期。 下列示例未考虑投资票据可能产生的任何税务后果。

如需了解标的资产的最新实际值，请参见下面的“标的资产”部分。每个标的资产的结束值将不包括根据该标的资产的股份或单位或该标的资产所包含的证券产生的股息或其他分配所获得的任何收益。此外，票据的所有支付均受发行人和担保人的信用风险影响。

风险因素

您对票据的投资涉及重大风险，其中许多风险与传统债务证券的风险不同。在考虑购买票据时，您应仅在仔细考虑票据投资的风险（包括以下讨论的风险）并与您的顾问一起根据您的具体情况后，才做出购买决定。如果您对票据的重要方面或一般财务事项不了解，那么票据不适合您。您应仔细查阅随附产品补充文件中第PS-3页开始的“风险因素”部分、随附的招股说明书补充文件中第S-7页和随附的招股说明书第7页中有关票据风险的更详细说明，每个部分均在下面第PS-30页中标识。

与结构相关的风险

•您的投资可能导致损失；不保证本金返还。票据在到期时没有固定的本金偿还金额。如果票据在到期前未被自动赎回，并且任何标的资产的结束价值低于其阈值，则在到期时，您的投资将面临标的资产中最差表现资产价值下降的1:1下行风险，您将因标的资产中最差表现资产的结束价值低于其起始价值的每个1%而损失本金的1%。在这种情况下，您将损失票据投资的大部分或全部。

•票据的回报仅限于票据期限内支付的或有票息支付的回报。无论任何标的资产的观察价值或结束价值超过其票息障碍或起始价值的程度如何，票据的回报仅限于票据期限内支付的或有票息支付。同样，到期时或在自动赎回时支付的金额永远不会超过本金金额和适用的或有票息支付的总和，无论任何标的资产的观察价值或结束价值超过其起始价值的程度如何。相比之下，直接投资于一个或多个标的资产中包含的证券将使您能够获得其价值上涨带来的收益。票据的任何回报都不会反映如果您实际拥有这些证券并收到其支付的股息或分配所得的回报。

•这些票据可能面临自动赎回，这将限制您在整个票据期限内获得附条件票息支付的能力。这些票据可能面临自动赎回。从2027年10月18日的赎回观察日开始，如果在任何赎回观察日，每个标的资产的观察值大于或等于其赎回值，这些票据将被自动赎回。如果在到期日之前自动赎回这些票据，您将在相应的赎回支付日有权获得提前赎回金额，此后将不再支付任何金额。在这种情况下，您将失去在自动赎回日期之后继续获得附条件票息支付的机会。如果在到期日之前赎回这些票据，您可能无法投资于具有类似风险水平的其他证券，这些证券可能提供与这些票据相似的回报。

•您可能无法获得任何附条件票息支付。这些票据不提供任何定期固定票息支付。这些票据的投资者不一定能在这些票据上获得任何附条件票息支付。如果在观察日，任何标的资产的观察值低于其票息障碍值，您将无法获得该观察日适用的附条件票息支付。如果在票据期限内的所有观察日，任何标的资产的观察值都低于其票息障碍值，您在票据期限内将无法获得任何附条件票息支付，并且也不会在票据上获得正回报。

•您在票据上的回报可能低于具有可比期限的传统债务证券的收益率。您在票据上获得的任何回报可能低于如果您购买具有相同到期日的传统债务证券所能获得的回报。因此，当您考虑通货膨胀等因素影响货币的时间价值时，您在票据上的投资可能无法反映您全部的机会成本。此外，如果在票据期限内利率上升，附条件票息支付（如有）可能低于具有可比期限的传统债务证券的收益率。

•或有票息支付、提前赎回金额或赎回金额（以适用者为准）将不会反映标的资产在观察日或行权观察日以外的水平变化。在票据期限内，标的资产在观察日或行权观察日以外的水平不会影响票据的支付。尽管如此，投资者在持有票据期间应一般了解标的资产的表现，因为标的资产的表现可能会影响票据的市场价值。结算机构将通过将每个或有票息支付的初始值、票息障碍值、行权值或阈值（以适用者为准）与每个标的资产的观察值或结束值进行比较，来确定每个或有票息支付是否应付，并计算提前赎回金额或赎回金额（以适用者为准）。其他标的资产的水平将不被考虑。因此，如果票据在到期前未被自动行权，且最差表现标的资产的结束值低于其阈值，则即使每个标的资产在估值日之前始终高于其阈值，您在到期时收到的金额也将少于本金金额。

•由于票据与标的资产中最差表现的（而非平均表现）挂钩，即使其中一个标的资产的观察值或结束值大于或等于其票息障碍值或阈值（以适用者为准），您可能无法获得任何收益，并可能损失票据的大部分或全部投资。您的票据与标的资产中最差表现的挂钩，一个标的资产的水平变化可能不会与其他标的资产的水平变化相关联。票据并未与由标的资产组成的组合挂钩，其中某个标的资产的贬值可能在一定程度上被其他标的资产的增值所抵消。在票据的情况下，每个标的资产的单独表现不会被合并，一个标的资产的水平贬值不会被其他标的资产的水平增值所抵消。即使某个标的资产的观察值在观察日达到或超过其票息障碍值，如果另一个标的资产在同一天的观察值低于其票息障碍值，您也不会获得该观察日的或有票息支付。此外，即使某个标的资产的结束值达到或超过其阈值，如果最差表现标的资产的结束值低于其阈值，您仍可能损失票据的大部分或全部投资。

的某个标的资产可能在一定程度上被其他标的资产的增值所抵消。在票据的情况下，每个标的资产的单独表现不会被合并，一个标的资产的水平贬值不会被其他标的资产的水平增值所抵消。即使某个标的资产的观察值在观察日达到或超过其票息障碍值，如果另一个标的资产在同一天的观察值低于其票息障碍值，您也不会获得该观察日的或有票息支付。此外，即使某个标的资产的结束值达到或超过其阈值，如果最差表现标的资产的结束值低于其阈值，您仍可能损失票据的大部分或全部投资。

•票据的任何付款均受我们信用风险和担保人的信用风险影响，我们或担保人的信用状况的任何实际或感知变化预计会影响票据的价值或任何应付金额。票据是我们无担保的高级债务证券。票据的任何付款将由担保人全额且无条件担保。票据不被任何其他实体担保。因此，您收到票据的任何付款将取决于我们和担保人是否有能力在适用的付款日偿还我们在票据下的各自义务，无论底层资产的表现如何。无法保证票据定价日后我们或担保人的财务状况会是什么样子。如果我们和担保人无法在到期时偿还各自的财务义务，您可能无法获得根据票据条款应付的金额。

此外，我们的信用评级和担保人的信用评级是评级机构对我们各自支付义务能力的评估。因此，在到期日之前，我们或担保人的信用状况的感知变化以及我们或担保人的信用评级的实际或预期下降，或我们各自证券的收益率与美国国债收益率之间的利差（“信用利差”）的上升可能会对票据的市场价值产生不利影响。然而，由于您在票据上的回报还取决于我们和担保人支付各自义务的能力以外的因素，例如底层资产的价值，我们或担保人的信用评级的改善不会减少与票据相关的其他投资风险。

•我们是一家金融子公司，因此没有独立的资产、运营或收入。我们是担保人的金融子公司，除了与我们由担保人担保的债务证券的发行、管理和付款相关的运营外，没有其他运营，并且在正常业务过程中依赖担保人和/或其其他子公司来履行我们在票据下的义务。因此，我们支付票据的能力可能受到限制。

估值和市场相关风险

•您为票据支付的公开发行价格超过了它们的初始预估价值。本定价补充文件封面上提供的票据初始预估价值仅为一种估算，该估算根据我们在定价日参考我们及我们关联方的定价模型确定。这些定价模型考虑了某些假设和变量，包括我们的信用利差和担保人的信用利差、担保人的内部融资利率、对冲交易的中间市场价格、对利率、股息和波动率的预期、价格敏感性分析以及票据的预期期限。这些定价模型部分依赖于对未来事件的某些预测，这些预测可能不正确。如果您在到期前尝试出售票据，其市场价值可能低于您支付的价格，也可能低于其初始预估价值。这是由于多种因素，包括底层资产水平的变化、担保人的内部融资利率的变化，以及公开发行价格中包含的承销折扣（如有）、推荐费和对冲相关费用，详见下文“票据的结构”部分。这些因素，加上票据存续期间的各种信用、市场和经济因素，预计会降低您在任何二级市场出售票据时可能获得的价格，并以复杂和不可预测的方式影响票据的价值。

•初始预估价值并不代表我们、BAC、BofAS或我们任何其他关联方在任何二级市场（如果有的话）在任何时候愿意购买您的票据的最低或最高价格。票据在发行后的任何时间的价值将根据许多无法准确预测的因素而变化，包括底层资产的表现、我们和BAC的信用状况以及市场条件的变化。

•我们无法保证您的票据的交易市场会发展或维持。我们将不会在任何证券交易所上市票据。我们无法预测票据在任何二级市场的交易情况，也无法预测该市场是流动的还是不流动的。

与冲突相关的风险

•我们、担保人及我们任何其他关联方（包括BofAS）的交易和对冲活动可能与您产生利益冲突，并可能对您在票据上的回报和市场价值产生不利影响。我们、担保人或我们其他关联方（包括BofAS）可能买卖由底层资产代表的证券，或底层资产或这些证券的期货或期权合约，或在底层资产或这些证券上交易的其他上市或场外衍生工具。虽然我们、担保人或我们其他关联方（包括BofAS）可能不时持有由底层资产代表的证券，除BAC普通股可能包含在底层资产中以外，我们、担保人及我们其他关联方（包括BofAS）并不控制任何包含在底层资产中的公司，也未核实任何其他公司的任何披露信息。我们、担保人或我们其他关联方（包括BofAS）可能出于自身或其自身账户、业务原因，或与对冲我们的风险相关而进行此类买卖。

票据项下的义务。这些交易可能会在您对票据的利益与我们、担保人及我们其他附属公司（包括美银证券）的利益之间产生利益冲突，这些利益可能涉及我们在自营账户中的利益，以及在促成交易（包括大宗交易）时的利益，这些交易是为我们或其他客户的账户进行的，以及在我们或他们管理的账户中进行的。这些交易可能会以对您在票据中的投资不利的方式影响相关资产的水平。在定价日或之前，我们、担保人或我们其他附属公司（包括美银证券或其他代表我们或他们行事的实体）可能进行的任何购买或出售行为（包括为了对冲我们与票据相关的预期风险而进行的交易），可能已经对相关资产的水平产生了不利影响。因此，相关资产的水平可能在定价日后发生变化，这可能对票据的市场价值产生不利影响。

我们、担保人或我们其他附属公司（包括美银证券）也可能进行了可能在定价日对相关资产水平产生不利影响的对冲活动。此外，这些对冲活动，包括对冲头寸的平仓，可能在到期前降低您的票据的市场价值，并可能对票据的支付金额产生不利影响。我们、担保人或我们其他附属公司（包括美银证券）可能在票据、相关资产或代表相关资产的证券上建立多头或空头头寸，并可能持有或转售票据、相关资产或代表相关资产的证券。例如，美银证券可能在从事任何市场做市活动时进行这些交易。我们无法保证这些活动不会对相关资产的水平、您在到期前的票据市场价值或票据的应付金额（如有）产生不利影响。

•计算代理机构可能存在潜在的利益冲突，计算代理机构是我们的一个附属公司。 我们有权任命和更换计算代理机构。我们的一家附属公司将成为票据的计算代理机构，因此将就票据做出各种决定，包括将支付给票据的金额。在某些情况下，这些职责可能导致其作为我们附属公司的地位与其作为计算代理机构的责任之间产生利益冲突。

与相关资产相关的风险

•票据涉及与小市值公司相关的风险。 RTY由小市值公司的股票组成。小市值公司的股票价格可能比大市值公司的股票价格更加波动。与大公司相比，小市值公司可能在不利的经济、市场、贸易和竞争条件下承受能力较弱。小市值公司也可能更容易受到与其产品或服务相关的不利发展的影响。

•科技行业的不利状况可能会降低您在票据上的收益。 NDXT 中包含的所有股票均由科技行业的公司发行。影响科技公司和严重依赖技术进步的公司的市场或经济因素可能对 NDXT 投资的价值产生重大影响。科技公司和严重依赖技术的公司的股票价格尤其容易受到技术产品周期的快速变化、快速产品过时、政府监管和竞争的影响，这些竞争既包括国内也包括国际竞争，包括来自生产成本较低的外国竞争对手的竞争。科技公司和严重依赖技术的公司股票，尤其是较小的、经验不足的公司的股票，往往比整体市场更具波动性。科技公司严重依赖专利和知识产权，这些权利的丧失或受损可能会对盈利能力产生不利影响。此外，科技行业公司可能会面临增长率和合格人员服务竞争的剧烈且常常难以预测的变化。这些因素中的任何一种都可能对票据的收益产生不利影响。因此，通过投资票据，您将无法从与多个行业公司相关的投资可能带来的多样化中受益。

•票据可能面临与外国证券市场相关的风险。 NDXT 包含某些外国权益证券。您应意识到，与外国权益证券价值挂钩的投资涉及特定风险。构成 NDXT 的外国证券市场可能流动性较低，并且可能比美国或其他证券市场更加波动，市场发展可能以不同于美国或其他证券市场的方式影响这些外国市场。为稳定这些外国证券市场而进行的直接或间接政府干预，以及外国公司中的交叉持股，可能会影响这些市场的交易价格和交易量。此外，关于外国公司的公开可用信息通常少于那些受美国证券交易委员会（SEC）报告要求约束的美国公司，而且外国公司受制于与美国报告公司适用的标准和要求不同的会计、审计和财务报告标准和要求。

外国国家证券的价格受该地理区域适用的政治、经济、金融和社会因素的影响。这些因素可能对这些证券市场产生不利影响，包括外国政府近期或未来可能改变经济和财政政策的可能性、可能实施或修改适用于外国公司或外国权益证券投资的外汇法或其他法律或限制的可能性，以及货币之间汇率波动的可能性、该地区可能发生敌对行动和政治不稳定的可能性，以及该地区可能发生自然灾害或不利公共卫生发展的可能性。此外，外国经济在许多重要方面可能与美国经济有利或不利地不同，例如国民生产总值的增长、通货膨胀率、资本再投资、资源和自给自足程度。

•NDXT包含的股票集中在某一行业。 NDXT包含科技行业公司的证券。因此，将决定凭证表现的一些股票集中在某一行业。尽管投资于凭证不会使持有人在NDXT包含的证券中拥有任何所有权或其他直接权益，

投资于凭证的收益将受到与直接投资于该行业公司相关的某些风险的影响。因此，通过投资于凭证，您将无法从投资于多个行业公司的多样化中获益。

•底层资产的发布者或发起人可能会以影响其水平的方式调整该底层资产，且发布者或发起人没有义务考虑您的利益。 底层资产的发布者或发起人可以添加、删除或替换该底层资产中包含的成分，或进行其他方法论上的更改，这可能会改变其水平。这些任何行动都可能对您的凭证价值产生不利影响。

税务相关风险

•投资于凭证的美国联邦所得税后果是不确定的，可能对凭证持有人不利。 没有任何立法、司法或行政权威直接涉及凭证或类似凭证的证券在美国联邦所得税目的上的分类。因此，投资于凭证的美国联邦所得税后果的许多方面尚不确定。根据凭证条款，您将与我们达成一致，将凭证视为附条件收益的单一金融合约，如下文“美国联邦所得税摘要—一般”所述。如果美国国税局（“IRS”）成功主张对凭证的替代分类，那么与凭证相关的收入、收益或损失的时机和性质可能会有所不同。不会就凭证向IRS提出任何裁定，也无法保证IRS会同意“美国联邦所得税摘要”部分中所述的内容。 我们敦促您就投资于凭证的所有美国联邦所得税后果方面咨询自己的税务顾问。

底层资产

本定价补充文件中关于相关资产的所有披露内容，包括但不限于其构成、计算方法以及组成部分的变化，均来自公开可获取的来源。该信息反映了NDXT的发起人、RTY的发起人和SPX的发起人（统称为“相关资产发起人”）的政策，并可能由这些发起人随时更改。相关资产发起人授权相关资产的版权和其他所有权利，但没有义务继续发布，也可能停止发布相关资产。如果任何相关资产发起人停止发布相关资产，其后果将在随附的产品补充文件中的“票据描述——指数中止”部分进行讨论。我们、担保人、计算代理机构或美国银行证券公司（BofAS）不对任何相关资产或任何后续指数的计算、维护或发布承担任何责任。我们、担保人、BofAS或我们任何其他关联方不对您作出有关相关资产未来表现的任何陈述。您应自行对相关资产进行调查。

纳斯达克-100^®科技行业指数

NDXT旨在衡量纳斯达克-100指数^®（“NDX”）中科技公司的表现。NDX旨在衡量根据市值排名，纳斯达克证券市场（“NASDAQ”）上市的100家最大的国内和国际非金融证券的表现。NDXT中每只股票的发行人根据行业分类基准（“ICB”）被归类为科技公司。

NDXT于2006年2月22日以1,000.00的基准值开始交易。NDXT由纳斯达克OMX集团公司（“纳斯达克OMX”）进行计算和发布。在管理NDXT时，纳斯达克OMX将根据其判断行使合理的裁量权。

证券入选标准与选择

要符合NDXT的入选条件，证券必须包含在NDX中。根据ICB，公司必须被归类为科技公司（任何归类在科技行业的公司）。“

所有符合证券入选标准的证券均包含在NDXT中。

成分股权重

NDXT是一个等权重指数。NDXT每季度重新平衡，使NDXT中的所有发行人具有相等的指数市值。NDXT的重新构成和重新平衡时间表与NDX相同。对于由多种证券代表的发行人，指数市值在其各自的指数证券中均等分配。指数份额是通过将每只指数证券的相应指数市值除以其最近的成交价格计算得出的。

NDXT指数计算

NDXT 的值等于 NDXT 市场价值除以 NDXT 除数。总体 NDXT 市场价值是每个 NDXT 股票的市场价值的总和，根据 NDXT 股票的等权重因子进行调整，该因子用于在上一次再平衡时分配相等的权重，如有任何公司行为，可能会进行调整。NDXT 股票的市场价值是通过将最近成交价乘以包含在 NDX 中的指数证券的股份数量来确定的。换句话说，NDXT 的值等于（i）每个 NDXT 股票的指数股份乘以（ii）每只股票的最近成交价（如有公司行为，已进行调整）乘以（iii）该股票的等权重因子的总和，除以（ii）NDXT 的除数。

价格回报 NDXT 除数计算方式为（i）NDXT 的当日市场价值除以（ii）前一日 NDXT 值的比率。

如果某指数证券在特定日期不在相关纳斯达克交易所交易，或相关纳斯达克交易所未开放交易，则使用该指数证券前一指数计算日的收盘价（如有在当日市场开盘前发生的公司行为，已进行调整）。如果某指数证券在交易日中被暂停交易，则使用最近的最后成交价，直到交易恢复。对于 NASDAQ 为相关纳斯达克交易所的证券，当其收盘时，最后成交价可能为纳斯达克官方收盘价。

NDXT 维护

删除政策

如果 NDXT 的组成部分因任何原因从 NDX 中移除，它也会在同一时间从 NDXT 中移除。

替换政策

当根据 ICB 分类为科技类的 NDX 组成部分被从 NDX 中移除时，它也会从 NDXT 中移除。因此，如果被添加到 NDX 的替换公司根据 ICB 分类为科技类，则它会被添加到 NDXT，并在指数生效日承担被移除公司的权重。

当根据ICB分类属于科技行业的NDX成分股被移除，且被替换的公司根据ICB分类不属于科技行业时，该公司将从NDXT中移除，并调整NDXT的除数以确保指数连续性。

新增政策

如果因任何原因将某证券加入NDX，该证券可能同时被加入NDXT。

公司行为

在计划的指数重组和再平衡事件之间的过渡期间，个别指数证券可能会受到各种公司行为和事件的影响，需要对指数进行维护和调整。

在某些情况下，公司行为和事件是根据所采用的加权方案或其他指数构建技术来处理的。在描述替代方法的地方，指数将遵循“非市值公司行为方法”。

指数股份调整

除了公司行为的直接结果外，NDXT在定期指数再平衡和再构成事件之间通常不会经历股份调整。

纳斯达克-100 指数^®

NDX 旨在衡量基于市值在纳斯达克上市的100家最大的国内和国际非金融证券的表现。NDX 反映了包括计算机硬件和软件、电信、零售/批发贸易和生物技术在内的主要行业组的公司。它不包含金融公司的证券，包括投资公司。

NDX 于1985年1月31日以基准值125.00开始交易。NDX 由纳斯达克公司计算和发布。在管理 NDX 时，纳斯达克公司会根据其认为适当的情况行使合理的裁量权。

基础股票资格标准

NDX 的资格仅限于特定类型的证券。NDX 可以纳入的证券类型包括外国或国内普通股票、普通股、存托凭证和跟踪股票。NDX 不包含的证券类型包括封闭式基金、可转换债务证券、交易所交易基金、有限责任公司、有限合伙权益、优先股、权利、受益权益的股份或单位、认股权证、单位和其他衍生证券。NDX 不包含投资公司的证券。就 NDX 资格标准而言，如果证券是代表非美国发行人证券的存托凭证，则对“发行人”的引用是指基础证券的发行人。

初始资格标准

要被纳入 NDX 的初始资格，证券必须满足以下标准：

•该证券的美国上市必须主要在一家美国纳斯达克关联交易所上市；

•该证券必须属于非金融公司；

•该证券的发行人目前不得处于破产程序中；

•该证券的三个月平均每日交易价值至少为500万美元；

•该证券的发行人不得已签订可能导致该证券不再符合 NDX 纳入资格的最终协议或其他安排；

NDX的计算方式

NDX的价值等于每个NDX证券的NDX份额权重（“NDX份额”）的总价值乘以每个证券的最后成交价（最后成交价指的是在纳斯达克的最后成交价），再除以NDX的除数。如果在市场开放期间NDX证券的交易被暂停，那么在交易恢复之前，将使用该证券的最后成交价进行所有NDX计算。如果在市场开放前交易被暂停，则使用前一交易日的最后成交价。确定NDX价值的公式如下：

NDX通常在计算时不考虑NDX证券的现金股息。NDX在交易日内进行计算，并在09:30:01至17:16:00 ET期间每秒发布一次。由于NDX证券的最后成交价可能有修正，NDX的收盘水平可能在17:15:00 ET之前发生变化。NDX的官方收盘值通常在17:16:00 ET发布。

NDX维护

NDX成分股的变更

在年度排名审查期间可能会对NDX成分股进行变更。此外，如果在年度审查之外的任何时间，确定某NDX证券的发行人不再符合继续保留在NDX中的条件，或被确定为不再符合继续保留在NDX中的条件，该证券将被替换为当前不在NDX中且符合NDX初始入选适用资格标准的最大市值发行人。

通常情况下，证券将按照其最后成交价从NDX中移除。然而，如果在移除时NDX证券在其主要上市市场被暂停交易，并且无法迅速确定官方收盘价，纳斯达克公司可以自行决定以0.00000001美元（“零价格”）将该NDX证券移除。该零价格将在市场收盘后、NDX官方收盘值发布之前应用于NDX证券。

除数调整

除数会被调整，以确保NDX成分股因公司行为（调整NDX证券的价格或股份）或NDX在交易时间之外的参与而发生变化时，不会影响NDX的价值。所有除数变更都会在相关指数证券市场的收盘后发生。

NDX季度再平衡

如果确定（1）市值最大的单个NDX证券的当前权重超过NDX的24.0%，或者（2）当前权重超过4.5%的证券的总体权重超过NDX的48.0%，则NDX将按季度进行再平衡。此外，如果纳斯达克公司认为有必要维护NDX的完整性和连续性，可能会在任何时候进行“特别再平衡”。如果在季度审查时满足上述任一或两个权重分布条件，或者纳斯达克公司认为有必要进行特别再平衡，则将进行权重再平衡。

如果满足第一个权重分布条件，并且市值最大的单个NDX证券的当前权重超过24.0%，则所有当前权重超过1.0%的证券（“大型证券”）的权重将按比例减少至1.0%，直到单个最大NDX证券的调整后权重达到20.0%。

如果满足第二个权重分布条件，并且当前权重超过4.5%的证券的总体权重（如适用，根据上一步调整后的权重）超过NDX的48.0%，则该组中所有大型证券的权重将按比例减少至1.0%，直到调整后的总体权重等于40.0%。

上述两种重新平衡步骤中任一或两种导致的大额证券总权重减少，将按照以下方式重新分配给权重低于1.0%的证券（“小证券”）。在第一次迭代中，最大小证券的权重将按一个系数进行放大，使其等于NDX的平均权重1.0%。其余较小的小证券的权重将按同一系数进行放大，但该系数会根据每个证券在小证券中的相对排名进行调整，使得在排名中NDX证券越小，其权重被放大的幅度就越小。此举旨在减少权重重新平衡对NDX中最小成分证券的市场影响。

在小证券重新平衡的第二次迭代中，第二大中小证券的权重（已在第一次迭代中调整）将被...

通过一个因子进行放大，使其等于NDX的平均权重1.0%。剩余较小证券的权重将根据这一相同因子进行放大，但该因子会根据每只证券在小型证券中的相对排名进行调整，使得在排名中越小的证券，其权重被放大的幅度越小。将进行额外的迭代，直到小型证券的权重总增加量等于大型证券因根据上述两种权重分配条件重新平衡而产生的权重总减少量。

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 Russell 2000^® Index

The RTY was developed by Russell Investments (“Russell”) before FTSE International Limited and Russell combined in 2015 to create FTSE Russell, which is wholly owned by London Stock Exchange Group. Additional information on the RTY is available at the following website: http://www.ftserussell.com. No information on that website is deemed to be included or incorporated by reference in this pricing supplement.

Russell began dissemination of the RTY on January 1, 1984. FTSE Russell calculates and publishes the RTY. The RTY was set to 135 as of the close of business on December 31, 1986. The RTY is designed to track the performance of the small capitalization segment of the U.S. equity market. As a subset of the Russell 3000^® Index, the RTY consists of the smallest 2,000 companies included in the Russell 3000^® Index. The Russell 3000^® Index measures the performance of the largest 3,000 U.S. companies, representing approximately 98% of the investable U.S. equity market. The RTY is determined, comprised, and calculated by FTSE Russell without regard to the Notes.

Selection of Stocks Comprising the RTY

Each company eligible for inclusion in the RTY must be classified as a U.S. company under FTSE Russell’s country-assignment methodology. If a company is incorporated, has a stated headquarters location, and trades in the same country (American Depositary Receipts and American Depositary Shares are not eligible), then the company is assigned to its country of incorporation. If any of the three factors are not the same, FTSE Russell defines three Home Country Indicators (“HCIs”): country of incorporation, country of headquarters, and country of the most liquid exchange (as defined by a two-year average daily dollar trading volume) from all exchanges within a country. Using the HCIs, FTSE Russell compares the primary location of the company’s assets with the three HCIs. If the primary location of its assets matches any of the HCIs, then the company is assigned to the primary location of its assets. If there is insufficient information to determine the country in which the company’s assets are primarily located, FTSE Russell will use the country from which the company’s revenues are primarily derived for the comparison with the three HCIs in a similar manner. FTSE Russell uses the average of two years of assets or revenues data to reduce potential turnover. If conclusive country details cannot be derived from assets or revenues data, FTSE Russell will assign the company to the country of its headquarters, which is defined as the address of the company’s principal executive offices, unless that country is a Benefit Driven Incorporation (“BDI”) country, in which case the company will be assigned to the country of its most liquid stock exchange. BDI countries include: Anguilla, Antigua and Barbuda, Bahamas, Barbados, Belize, Bermuda, Bonaire, British Virgin Islands, Cayman Islands, Channel Islands, Cook Islands, Curacao, Faroe Islands, Gibraltar, Guernsey, Isle of Man, Jersey, Liberia, Marshall Islands, Panama, Saba, Sint Eustatius, Sint Maarten, and Turks and Caicos Islands. For any companies incorporated or headquartered in a U.S. territory, including Puerto Rico, Guam, and U.S. Virgin Islands, a U.S. HCI is assigned.

All securities eligible for inclusion in the RTY must trade on a major U.S. exchange. Stocks must have a closing price at or above $1.00 on their primary exchange on the last trading day in May to be eligible for inclusion during annual reconstitution. However, in order to reduce unnecessary turnover, if an existing member’s closing price is less than $1.00 on the last day of May, it will be considered eligible if the average of the daily closing prices (from its primary exchange) during the month of May is equal to or greater than $1.00. Initial public offerings are added each quarter and must have a closing price at or above $1.00 on the last day of their eligibility period in order to qualify for index inclusion. If an existing stock does not trade on the “rank day” (typically the last trading day in May but a confirmed timetable is announced each spring) but does have a closing price at or above $1.00 on another eligible U.S. exchange, that stock will be eligible for inclusion.

An important criterion used to determine the list of securities eligible for the RTY is total market capitalization, which is defined as the market price as of the last trading day in May for those securities being considered at annual reconstitution times the total number of shares outstanding. Where applicable, common stock, non-restricted exchangeable shares and partnership units/membership interests are used to determine market capitalization. Any other form of shares such as preferred stock, convertible preferred stock, redeemable shares, participating preferred stock, warrants and rights, installment receipts or trust receipts, are excluded from the calculation. If multiple share classes of common stock exist, they are combined. In cases where the common stock share classes act independently of each other (e.g., tracking stocks), each class is considered for inclusion separately. If multiple share classes exist, the pricing vehicle will be designated as the share class with the highest two-year trading volume as of the rank day in May.

Companies with a total market capitalization of less than $30 million are not eligible for the RTY. Similarly, companies with only 5% or less of their shares available in the marketplace are not eligible for the RTY. Royalty trusts, limited liability companies, closed-end investment companies (companies that are required to report Acquired Fund Fees and Expenses, as defined by the SEC, including business development companies), blank check companies, special purpose acquisition companies, and limited partnerships are also ineligible for inclusion. Bulletin board, pink sheets, and over-the-counter traded securities are not eligible for inclusion. Exchange traded funds and mutual funds are also excluded.

Annual reconstitution is a process by which the RTY is completely rebuilt. Based on closing levels of the company’s common stock on its primary exchange on the rank day of May of each year, FTSE Russell reconstitutes the composition of the RTY using the then existing market capitalizations of eligible companies. Reconstitution of the RTY occurs on the last Friday in June or, when the last Friday in June is the 29th or 30th, reconstitution occurs on the prior Friday. In addition, FTSE Russell adds initial public offerings to the RTY on a quarterly basis based on total market capitalization ranking within the market-adjusted capitalization breaks established during the most recent reconstitution. After membership is determined, a security’s shares are adjusted to include only those shares available to the public. This is often referred to as “free float.” The purpose of the adjustment is to exclude from market calculations the capitalization that is not available for purchase and is not part of the investable opportunity set.

The S&P 500^® Index

The SPX includes a representative sample of 500 companies in leading industries of the U.S. economy. The SPX is intended to provide an indication of the pattern of common stock price movement. The calculation of the level of the SPX is based on the relative value of the aggregate market value of the common stocks of 500 companies as of a particular time compared to the aggregate average market value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943.

The SPX includes companies from eleven main groups: Communication Services; Consumer Discretionary; Consumer Staples; Energy; Financials; Health Care; Industrials; Information Technology; Real Estate; Materials; and Utilities. S&P Dow Jones Indices LLC (“SPDJI”), the sponsor of the SPX, may from time to time, in its sole discretion, add companies to, or delete companies from, the SPX to achieve the objectives stated above.

SPDJI calculates the SPX by reference to the prices of the constituent stocks of the SPX without taking account of the value of dividends paid on those stocks. As a result, the return on the Notes will not reflect the return you would realize if you actually owned the SPX constituent stocks and received the dividends paid on those stocks.

Computation of the SPX

While SPDJI currently employs the following methodology to calculate the SPX, no assurance can be given that SPDJI will not modify or change this methodology in a manner that may affect payments on the Notes.

Historically, the market value of any component stock of the SPX was calculated as the product of the market price per share and the number of then outstanding shares of such component stock. In March 2005, SPDJI began shifting the SPX halfway from a market capitalization weighted formula to a float-adjusted formula, before moving the SPX to full float adjustment on September 16, 2005. SPDJI’s criteria for selecting stocks for the SPX did not change with the shift to float adjustment. However, the adjustment affects each company’s weight in the SPX.

Under float adjustment, the share counts used in calculating the SPX reflect only those shares that are available to investors, not all of a company’s outstanding shares. Float adjustment excludes shares that are closely held by control groups, other publicly traded companies or government agencies.

In September 2012, all shareholdings representing more than 5% of a stock’s outstanding shares, other than holdings by “block owners,” were removed from the float for purposes of calculating the SPX. Generally, these “control holders” will include officers and directors, private equity, venture capital and special equity firms, other publicly traded companies that hold shares for control, strategic partners, holders of restricted shares, ESOPs, employee and family trusts, foundations associated with the company, holders of unlisted share classes of stock, government entities at all levels (other than government retirement/pension funds) and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. However, holdings by block owners, such as depositary banks, pension funds, mutual funds and ETF providers, 401(k) plans of the company, government retirement/pension funds, investment funds of insurance companies, asset managers and investment funds, independent foundations and savings and investment plans, will ordinarily be considered part of the float.

Treasury stock, stock options, restricted shares, equity participation units, warrants, preferred stock, convertible stock, and rights are not part of the float. Shares held in a trust to allow investors in countries outside the country of domicile, such as depositary shares and Canadian exchangeable shares, are normally part of the float unless those shares form a control block. If a company has multiple classes of stock outstanding, shares in an unlisted or non-traded class are treated as a control block.

For each stock, an investable weight factor (“IWF”) is calculated by dividing the available float shares by the total shares outstanding. Available float shares are defined as the total shares outstanding less shares held by control holders. This calculation is subject to a 5% minimum threshold for control blocks. For example, if a company’s officers and directors hold 3% of the company’s shares, and no other control group holds 5% of the company’s shares, SPDJI would assign that company an IWF of 1.00, as no control group meets the 5% threshold. However, if a company’s officers and directors hold 3% of the company’s shares and another control group holds 20% of the company’s shares, SPDJI would assign an IWF of 0.77, reflecting the fact that 23% of the company’s outstanding shares are considered to be held for control. For companies with multiple share class lines, the 5% share change threshold are based on each individual multiple share class line rather than total company shares.

The SPX is calculated using a base-weighted aggregate methodology. The level of the SPX reflects the total market value of all component stocks relative to the base period of the years 1941 through 1943. An indexed number is used to represent the results of this calculation in order to make the level easier to work with and track over time. The actual total market value of the component stocks during the base period of the years 1941 through 1943 has been set to an indexed level of 10. This is often indicated by the notation 1941- 43 = 10. In practice, the daily calculation of the SPX is computed by dividing the total market value of the component stocks by the “index divisor.” By itself, the index divisor is an arbitrary number. However, in the context of the calculation of the SPX, it serves as a link to the original base period level of the SPX. The index divisor keeps the SPX comparable over time and is the manipulation point for all adjustments to the SPX, which is index maintenance.

Index Maintenance

Index maintenance includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends, and stock price adjustments due to company restructuring or spinoffs. Some corporate actions, such as stock splits and stock dividends,

\n \n

require changes in the common shares outstanding and the stock prices of the companies in the SPX, and do not require index divisor adjustments.

To prevent the level of the SPX from changing due to corporate actions, corporate actions which affect the total market value of the SPX require an index divisor adjustment. By adjusting the index divisor for the change in market value, the level of the SPX remains constant and does not reflect the corporate actions of individual companies in the SPX. Index divisor adjustments are made after the close of trading and after the calculation of the SPX closing level.

Changes in a company’s shares outstanding of 5.00% or more due to mergers, acquisitions, public offerings, tender offers, Dutch auctions, or exchange offers are made as soon as reasonably possible. Share changes due to mergers or acquisitions of publicly held companies that trade on a major exchange are implemented when the transaction occurs, even if both of the companies are not in the same headline index, and regardless of the size of the change. All other changes of 5.00% or more (due to, for example, company stock repurchases, private placements, redemptions, exercise of options, warrants, conversion of preferred stock, notes, debt, equity participation units, at-the-market offerings, or other recapitalizations) are made weekly and are announced on Fridays for implementation after the close of trading on the following Friday. Changes of less than 5.00% are accumulated and made quarterly on the third Friday of March, June, September, and December, and are usually announced two to five days prior.

If a change in a company’s shares outstanding of 5.00% or more causes a company’s IWF to change by five percentage points or more, the IWF is updated at the same time as the share change. IWF changes resulting from partial tender offers are considered on a case by case basis.

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 will 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, 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 $993.25 per $1,000.00 in principal amount of Notes. In addition to the underwriting discount, if any, an affiliate of BofA Finance will pay a referral fee of up to $6.75 per $1,000.00 in principal amount of Notes in connection with the distribution of the Notes to other registered broker-dealers.

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, resulted 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.

For further information, see “Risk Factors” beginning on page PS-3 and “Supplemental Use of Proceeds” on page PS-15 of the accompanying product supplement.

Validity of the Notes

In the opinion of Sidley Austin LLP, as counsel to BofA Finance and BAC, when the trustee has made the appropriate entries or notations on Schedule 1 to the master global note that represents the Notes (the “Master Note”) identifying the Notes offered hereby as supplemental obligations thereunder in accordance with the instructions of BofA Finance, and the Notes have been delivered against payment as contemplated herein, such Notes will be valid and binding obligations of BofA Finance, and the related guarantee will be a valid and binding obligation of BAC, in each case, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith), provided that such counsel expresses no opinion as to the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law on the conclusions expressed above. This opinion is given as of the date hereof and is limited to the Delaware Limited Liability Company Act, the Delaware General Corporation Law and the laws of the State of New York as in effect on the date hereof. In addition, this opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the indenture and due authentication of the Master Note and the genuineness of signatures and certain factual matters, all as stated in the letter of such counsel dated October 1, 2025 which has been filed as Exhibit 5.3 to the Company’s Registration Statement on Form S-3 filed with the Securities and Exchange Commission on October 1, 2025.

U.S. Federal Income Tax Summary

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

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

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

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

General

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

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

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

We will not attempt to ascertain whether any issuer of a component stock included in an 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 one or more component stocks included in an 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 component stocks included in each Underlying and consult your tax advisor regarding the possible consequences to you, if any, if any issuer of a component stock included in an Underlying is or becomes a PFIC or is or becomes a United States real property holding corporation.

U.S. Holders

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

Upon receipt of a cash payment at maturity or upon a sale, exchange or redemption of the Notes prior to maturity, a U.S. Holder generally will recognize capital gain or loss equal to the difference between the amount realized (other than amounts representing any Contingent Coupon Payment, which would be taxed as described above) and the U.S. Holder’s tax basis in the Notes. A U.S. Holder’s tax basis in the Notes will equal the amount paid by that holder to acquire them. 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.

\n \n

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

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

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

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

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

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

Because each Underlying is an index that periodically rebalances, it is possible that the Notes could be treated as a series of contingent income-bearing single financial contracts, each of which matures on the next rebalancing date. If the Notes were properly characterized in such a manner, a U.S. Holder would be treated as disposing of the Notes on each rebalancing date in return for new Notes that mature on the next rebalancing date, and a U.S. Holder would accordingly likely recognize capital gain or loss on each rebalancing date equal to the difference between the holder’s tax basis in the Notes (which would be adjusted to take into account any prior recognition of gain or loss) and the fair market value of the Notes on such date.

Non-U.S. Holders

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

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

\n \n

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

A “dividend equivalent” payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a Non-U.S. Holder. Under Treasury regulations, payments (including deemed payments) with respect to equity-linked instruments (“ELIs”) that are “specified ELIs” may be treated as dividend equivalents if such specified ELIs reference an interest in an “underlying security,” which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, IRS guidance provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2029. Based on our determination that the Notes are not delta-one instruments, Non-U.S. Holders should not be subject to withholding on dividend equivalent payments, if any, under the Notes. However, it is possible that the Notes could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Underlyings or the Notes, and following such occurrence the Notes could be treated as subject to withholding on dividend equivalent payments. Non-U.S. Holders that enter, or have entered, into other transactions in respect of the Underlyings or the Notes should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the Notes and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.

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

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