Ticker: ETECStock Exchange: Nasdaq

Investment Objective

The iShares Breakthrough Environmental Solutions ETF (the “Fund”) seeks to track the investment results of an index composed of U.S. and non-U.S. companies involved in breakthrough innovations and development of new technologies that address the climate transition.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and any extraordinary expenses.

You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year	3 Years	5 Years	10 Years

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to track the investment results of the Morningstar® Global Emerging Green Technologies Select IndexSM (the “Underlying Index”), which measures the performance of equity securities issued by U.S. and non-U.S. companies involved in breakthrough innovations and new technologies that seek to promote sustainability, as determined by Morningstar or its affiliates (“Morningstar” or the “Index Provider”).

To construct the Underlying Index, the Index Provider begins with securities from the Morningstar Global Markets ex India Index (the “Parent Index”) and applies a number of exclusions. The Index Provider excludes constituents with an average three-month trailing daily trading volume of less than $2 million or a free float market capitalization of less than $300 million. The Index Provider also excludes the securities of companies that it identifies as being involved in the business of tobacco, companies involved with controversial weapons, producers and retailers of civilian firearms, and companies involved in thermal coal mining, thermal coal-based power generation or the extraction of oil sands. Certain exclusions (e.g., controversial and nuclear weapons or the production of tobacco products) are categorical, and other exclusions are based on percentage of revenue or ownership thresholds. Additionally, the Index Provider excludes companies that it determines are involved in controversies related to the ten United Nations Global Compact (“UNGC”) principles, which are classified into four categories: human rights, labor, environment and anti-corruption, as well as companies for which a third party data provider, Sustainalytics, has assigned a controversy score of 5 (indicating the company experienced an event with a severe impact on the environment and society), or for which the Index Provider has not assigned a controversy score. The Index Provider will apply a series of revenue screens on the resulting eligible constituents.

First, Morningstar equity analysts evaluate each company’s
revenue that is derived from “sustainable activities involvement,” as calculated by the Index Provider. Sustainable activities involvement could include the distribution and management of energy efficient materials or products, or pollution remediation services. The Index Provider determines whether a company has sustainable activities involvement revenue by breaking down the companywide revenue into the following eight sustainable themes: Energy Efficiency, Green Buildings, Green Transportation, Pollution Prevention & Reduction, Renewable Energy, Resource Efficiency Technologies & Services, Sustainable Agriculture, Food & Forestry, and Water.

The Index Provider applies the first revenue screen, excluding companies with a total sustainable activities involvement revenue of less than 25% from the Underlying Index. Following the first revenue screen, Morningstar equity analysts research the

products or services identified within the eight sustainable themes to determine whether the products or services fall within the following categories, as defined by Morningstar: “green technologies”, “green services” or “green certifications.” Green technologies are products and services that are highly innovative toward sustainability. Green services are services which rely on innovative technologies developed by other companies. Green certified means that an industry regulator or other third party has certified the product or service as sustainable or has certified the elements within the supply chain of the product or service as sustainable. Morningstar equity analysts consider various metrics to make this determination (e.g., research and development as a percentage of revenue and company-level patent application data). Morningstar excludes all revenue tied to products and services classified as “green services” or “green certified.” Morningstar reviews the green technologies and assesses whether each qualifies as an “emerging green technology.”

The products and services classified as “green technologies” are assessed by Morningstar equity analysts and distributed within the Rogers Innovation Adoption Curve (“Adoption Curve”). The Adoption Curve is a theory created by Professor Everett Rogers that explains the rate at which the population adopts a new product, service, or technology over time, and which labels each product or service as one of five adoption stages: Innovators, Early Adopters, Early Majority, Late Majority, and Laggards. Morningstar assesses a product or service’s total addressable market and current market share to determine the adoption stage. Morningstar Equity Research classifies the products and services that are labeled Innovators, Early Adopters, and Early Majority as “emerging green technologies”. Once Morningstar identifies the emerging green technologies, Morningstar applies a second revenue screen: companies with 25% or more of their revenue represented by emerging green technologies are eligible for inclusion in the Underlying Index.

Following the second revenue screen, the resulting constituents receive an innovation score based on their products’ and/or services’ adoption stage, as follows:

• Innovation Score of 1: Early Majority

• Innovation Score of 2: Early Adopters

• Innovation Score of 3: Innovators

The Index Provider calculates a company-level aggregate score by multiplying the company’s revenue percentage of each product and/or service identified as an emerging green technology within each of the eight sustainable themes, and the product and/or service’s innovation score, creating a “product score”. Each product score is summed across the company’s products and/or services, resulting in the company’s aggregate score.

For example, suppose Morningstar analyzed Company A’s products and services across the eight sustainable themes, and found that 71.7% of Company A’s revenue is allocated to the Energy Efficiency theme from Product X, and 28.3% of its revenue is allocated to the Green Transportation theme from Product Y. Morningstar has determined both products are emerging green technologies and that Product X is an “innovator” on the Adoption Curve, earning an innovation score of 3, and Product Y is an “early adopter,” earning an innovation score of 2. Each product’s revenues are multiplied by its respective innovation scores to determine its product score. Product X’s resulting product score is 2.15 (71.7% times 3), and Product Y’s resulting product score is

S-2

0.57 (28.3% times 2). Company A’s resulting aggregate score is 2.72, resulting in a Tier 1 designation.

Once Morningstar calculates each constituent’s aggregate score, Morningstar designates each constituent as either Tier 1 or Tier 2 based on their aggregate score. Tier 1 issuers are those with an aggregate score of 1.5 or higher. Tier 2 issuers are those with an aggregate score of less than 1.5. All Tier 1 constituents are selected for the Underlying Index. Morningstar ranks Tier 2 issuers with preference given to issuers with a higher aggregate score over a lower aggregate score, then a smaller market capitalization over a larger market capitalization. If there are fewer than 50 Tier 1 constituents, the shortfall is filled with Tier 2 constituents, and the Underlying Index is capped at 50 constituents.

Constituents are float market capitalization-weighted with a 6% cap for individual stocks and each industry is capped at 15%. Additionally, individual constituents with weights of 4.5% or greater in aggregate cannot compose more than 45% of the Underlying Index. The Underlying Index is reconstituted annually each December and rebalanced quarterly. The Index Provider does not require that each of the eight sustainable themes be included in the Underlying Index, nor does it require the inclusion of a minimum number of Tier 1 constituents. In addition, constituents may operate business lines that generate revenues in industries in addition to those related to breakthrough innovations and new technologies and may be associated with multiple industries or sectors.

The Underlying Index includes small-, mid- and large-capitalization companies and may change over time. As of July 31, 2025, a significant portion of the Underlying Index is represented by securities of companies in the consumer goods and services, industrials and technology industries or sectors. As of July 31, 2025, the Underlying Index consisted of securities from the following countries: China, Denmark, Finland, Germany, Japan, South Korea, Taiwan, and the U.S.

BFA uses an indexing approach to try to achieve the Fund’s investment objective. The Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by aiming to keep portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to that of an applicable underlying index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally will invest at least 90% of its assets in the component securities of the Underlying Index and in investments that have economic characteristics that are substantially identical to the component securities of the Underlying Index (i.e., depositary receipts representing securities of the Underlying Index) and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is sponsored by Morningstar, which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below, any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective. Certain key risks are prioritized below (with others following in alphabetical order), but the relative significance of any risk is difficult to predict and may change over time. You should review each risk factor carefully.

S-3

market and business risks of other companies, industries or sectors. In addition, these companies may depend on intellectual property or patent rights to protect their innovations or new technologies, which may be difficult to prevent the misappropriation of, and are susceptible to competitors that may develop substantially similar or superior products or services.

ESG Risk. To the extent that the Underlying Index uses criteria related to the ESG characteristics of issuers, this may limit the types and number of investment opportunities available to the Fund and, as a result, the Fund may underperform other funds whose underlying index does not use ESG criteria. The Underlying Index’s use of ESG criteria may result in the Fund investing in, or allocating greater weight to, securities or market sectors that underperform the market as a whole or underperform other funds that use ESG criteria. In addition, the use of representative sampling may result in divergence of the Fund’s overall ESG characteristics or ESG risk from those of the Underlying Index. The Index Provider may evaluate security-level ESG data and, if applicable, ESG objectives or constraints that are relevant to the Underlying Index only at index reviews or rebalances. Securities included in the Underlying Index may cease to meet the relevant ESG criteria but may nevertheless remain in the Underlying Index and the Fund until the next review or rebalance by the Index Provider. As a result, certain securities in the Underlying Index, or the Underlying Index as a whole, may not meet the relevant ESG objectives or constraints at all times.

Thematic Investing Risk. The Fund relies on the Index Provider to identify securities that reflect the relevant themes and sub-themes for inclusion in the Underlying Index. There is no guarantee that the Underlying Index or the Fund will reflect the intended theme and sub-theme exposures. The Fund’s performance may suffer if such securities are not correctly identified, if a theme or sub-theme develops in an unexpected manner, or if securities in the Underlying Index do not benefit from the development of a theme or sub-theme. The Fund’s performance may also be impacted if securities that are not related to the theme or sub-theme are included in the Underlying Index.

Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. The value of a security may decline for a number of reasons that may directly relate to the issuer as well as due to general industry or market conditions. Common stock is subordinated to preferred securities and debt in a company’s capital structure. Common stock has the lowest priority, and the greatest risk, with respect to dividends and any liquidation payments in the event of an issuer’s bankruptcy.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. Local, regional or global events such as war, acts of terrorism, pandemics or other public health issues, recessions, the prospect or occurrence of a sovereign default or other financial crisis, or other events could have a significant impact on the Fund and its investments and could result in increased premiums or discounts to the Fund’s NAV.

Index-Related Risk. The Index Provider may rely on various sources of information to assess the criteria of components of the

Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor BFA can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Fund meeting its investment objective. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur, and the Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider and could cause the Index Provider to postpone a scheduled rebalance. This could cause the Underlying Index to vary from its normal or expected composition.

Asset Class Risk. The securities and other assets in the Underlying Index or in the Fund’s portfolio may underperform in comparison to financial markets generally, a particular financial market, another index, or other asset classes.

Assets Under Management (AUM) Risk. From time to time, an Authorized Participant (as defined below in Authorized Participant Concentration Risk), a third-party investor, the Fund’s adviser, an affiliate of the Fund’s adviser, or another fund may invest in the Fund and hold its investment for a specific period of time to allow the Fund to achieve size or scale. There can be no assurance that any such entity would not redeem its investment or that the size of the Fund would be maintained at such levels, which could negatively impact the Fund.

Authorized Participant Concentration Risk. An “Authorized Participant” is a member or participant of a clearing agency registered with the SEC, which has a written agreement with the Fund or one of its service providers that allows the Authorized Participant to place orders for the purchase and redemption of creation units (“Creation Units”). Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. There are a limited number of institutions that may act as Authorized Participants for the Fund, including on an agency basis on behalf of other market participants. No Authorized Participant is obligated to engage in creation or redemption transactions. To the extent that Authorized Participants exit the business or do not place creation or redemption orders for the Fund and no other Authorized Participant places orders, Fund shares are more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities or other assets of one or more issuers, countries or other geographic units, markets, industries, project types, or asset classes.

Consumer Goods and Services Companies Risk. Consumer goods and services companies (“consumer companies”) face risks related to changes in consumer preferences and disposable income, commodity prices, government regulation, supply chain disruptions, damage to brand or reputation, economic slowdown and labor shortages, among other things.

S-4

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the NAV could decline if the currency of the non-U.S. market in which the Fund invests depreciates against the U.S. dollar or if there are delays or limits on the repatriation of foreign currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund’s NAV may change quickly and without warning. In addition, the Fund may incur costs in connection with conversions between U.S. dollars and foreign currencies.

Custody Risk. Less developed securities markets are more likely to experience problems with the clearing and settlement of trades, as well as the custody of securities and other assets by local banks, agents and depositories. These issues may have an adverse impact on the Fund, including losses or delays in payments, delivery or recovery of money or other assets.

Industrial Companies Risk. Industrial companies face a number of risks, including supply chain and distribution disruptions, business interruptions, product obsolescence, third-party vendor risks, cyber attacks, trade disputes, product recalls, liability claims, scarcity of materials or parts, excess capacity, changes in consumer preferences, and volatility in commodity prices and currencies. The performance of such companies may also be affected by technological developments, labor relations, legislative and regulatory changes, government spending policies, and changes in domestic and international economies.

Issuer Risk. The performance of the Fund depends on the performance of individual securities or other assets to which the Fund has exposure. The value of securities or other assets may decline, or perform differently from the market as a whole, due to changes in the financial condition or credit rating of the issuer or counterparty.

Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller-capitalization companies to adapt to changing market conditions and competitive challenges. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller-capitalization companies. The performance of large-capitalization companies could trail the overall performance of the broader securities markets.

Large Shareholder and Large-Scale Redemption Risk. Certain shareholders of the Fund, including an Authorized Participant, a third-party investor, the Fund’s adviser, an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own or manage a substantial amount of Fund shares, or may hold their investment in the Fund for a limited period of time. There can be no assurance that any large shareholder or large group of shareholders would not redeem their investment. Redemptions of a large number of Fund shares could require the Fund to dispose of assets to meet the redemption requests, which can accelerate the realization of taxable income and/or capital gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such year. In some circumstances, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. These large redemptions may also force the Fund to sell portfolio

securities or other assets when it might not otherwise do so, which may negatively impact the Fund’s NAV, increase the Fund’s brokerage costs and/or have a material effect on the market price of Fund shares.

Management Risk. The Fund generally does not attempt to take defensive positions under any market conditions, including declining markets. As the Fund will not fully replicate the Underlying Index and may hold securities or other assets not included in the Underlying Index, it is subject to the risk that the investment strategy of BFA may not produce the intended results. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the Fund will achieve its investment objective.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares (including through a trading halt), losses from trading in secondary markets, periods of high volatility, and disruptions in the process of creating and redeeming Fund shares. Any of these factors, among others, may lead to the Fund’s shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

Mid-Capitalization Companies Risk. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments. The securities of mid-capitalization companies may be more volatile and less liquid than those of large-capitalization companies. As a result, the Fund’s share price may be more volatile than that of a fund with a greater investment in large-capitalization stocks.

National Closed Market Trading Risk. To the extent that securities or other assets held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between such asset’s current price and its last quoted price (i.e., the quote from the closed foreign market to the Fund). The impact of a closed foreign market on the Fund is likely to be greater where a large portion of the Fund’s holdings trade on a closed foreign market or when a foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other funds.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that, compared with funds that are classified as “diversified,” the Fund may invest a greater percentage of its assets in securities or other instruments representing a small number of issuers or counterparties and thus may be more susceptible to the risks associated with these particular issuers or counterparties. As a result, the Fund's performance may depend to a greater extent on the performance of a small number of issuers or counterparties, which may lead to more volatility in the Fund’s NAV.

Non-U.S. Securities Risk. Securities issued by non-U.S. issuers (including depositary receipts) are subject to different legal, regulatory, political, economic, and market risks than securities

S-5

issued by U.S. issuers. These risks include greater market volatility, less market liquidity, higher transaction costs, expropriation, confiscatory taxation, adverse changes in foreign investment or currency control regulations, restrictions on the repatriation of capital, and political instability. Non-U.S. issuers may be subject to different accounting, audit and financial reporting standards than U.S. issuers, and there may be less publicly available information about non-U.S. issuers. Foreign market trading hours, different clearing and settlement procedures, and holiday schedules may limit the Fund's ability to engage in portfolio transactions. To the extent that investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. The Fund is specifically exposed to Asian Economic Risk.

Operational and Technology Risks. The Fund is directly and indirectly susceptible to operational and technology risks, including those related to human errors, processing errors, communication errors, systems failures, cybersecurity incidents, and the use of artificial intelligence and machine learning (“AI”), which may result in losses for the Fund and its shareholders or may impair the Fund’s operations. While the Fund’s service providers are required to have appropriate operational, information security and cybersecurity risk management policies and procedures, their methods of risk management may differ from those of the Fund. Operational and technology risks for the issuers in which the Fund invests could also result in material adverse consequences for such issuers and may cause the Fund’s investments in such issuers to lose value.

Reliance on Trading Partners Risk. The Fund invests in countries or regions whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund's investments. Through its holdings of securities of certain issuers, the Fund is specifically exposed to Asian Economic Risk, European Economic Risk and U.S. Economic Risk.

Risk of Investing in China. Investments in Chinese securities, including certain Hong Kong-listed and U.S.-listed securities, are subject to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. Despite economic and market reforms in recent decades, the Chinese government’s control over certain sectors and enterprises and significant regulation of investment and industry are still pervasive. Chinese companies are subject to the risk that Chinese authorities can intervene in their operations and structure. Chinese markets generally continue to experience inefficiency, a lack of publicly available information and/or political and social instability and may be subject to volatility and pricing anomalies resulting from governmental influence. Internal social unrest or confrontations with other countries, including military conflicts in response to such events, may disrupt China’s economy and markets and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher inflation.

including purchasing restrictions, sanctions, export controls, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers in which the Fund invests. Incidents involving China’s or the region’s security may adversely affect the Chinese economy and markets and the Fund’s investments.

The Chinese economy is highly reliant on trade. A reduction in spending on Chinese products and services, supply chain diversification, the institution of additional tariffs or other trade barriers (including as a result of heightened trade tensions or a trade war between China and the U.S. or in response to actual or alleged Chinese cyber activity) or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy. The Underlying Index may include companies that are subject to economic or trade restrictions (but not investment restrictions) imposed by the U.S. or other governments due to national security, human rights or other concerns of such government. So long as these restrictions do not include restrictions on investments, the Fund is generally expected to invest in such companies, consistent with its objective to track the performance of the Underlying Index.

Chinese companies, including those listed on U.S. exchanges, are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries. As a result, information about the Chinese securities in which the Fund invests may be less reliable or complete. Chinese companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, or for other reasons, which would significantly decrease the liquidity and value of the securities. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies, and shareholders may have limited legal remedies.

Many Chinese companies listed on U.S. exchanges use variable interest entities or “VIEs” in their structure as a result of foreign ownership restrictions. Any change in the operations of entities in a VIE structure, the status of VIE contractual arrangements or the legal or regulatory environment in China could result in significant, and possibly permanent and/or total, losses for investments in VIE issuers. The Fund does not select investments based on investor protection considerations.

Risk of Investing in Developed Countries. The Fund’s investment in developed country issuers will subject the Fund to legal, regulatory, political, currency, security, economic and other risks associated with developed countries. Developed countries tend to represent a significant portion of the global economy and have generally experienced slower economic growth than some less developed countries. Certain developed countries have experienced security concerns, such as war, terrorism and strained international relations. Incidents involving a country’s or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s investments. In addition, developed countries may be adversely impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.

S-6

Risk of Investing in Emerging Markets. Investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. The risks of emerging markets may include, among others, greater market volatility; political, legal, economic, and social instability; less developed securities markets, including settlement, custody and valuation processes; government expropriation or nationalization of assets; greater volatility in currency exchange rates; more capital controls; less governmental supervision and regulation; and less stringent accounting, auditing and disclosure requirements. There may be significant obstacles to obtaining information necessary for investigations into or litigation against companies, and shareholders may have limited legal remedies. The Fund does not select investments based on investor protection considerations. Emerging market securities may face liquidity challenges, and the Fund may be unable to liquidate its positions in such securities at a favorable time or price.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Small-Capitalization Companies Risk. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments. The securities of small-capitalization companies may be more volatile and less liquid than those of mid- and large-capitalization companies. As a result, the Fund’s share price may be more volatile than that of a fund with a greater investment in large- or mid-capitalization stocks.

Small Fund Risk. When the Fund’s size is small, the Fund may experience low trading volume and wide bid/ask spreads. The Fund’s performance near its inception date may not represent how the Fund will perform in the future or with a larger asset base. In addition, the Fund may face the risk of being delisted if it does not meet certain requirements set by the listing exchange. Any resulting liquidation of the Fund could lead to elevated transaction costs for the Fund and negative tax consequences for its shareholders.

developments, such as artificial intelligence and machine learning. Technology companies also depend heavily on intellectual property rights and may be adversely affected by the loss or impairment of those rights. Technology companies may face increased government scrutiny and may be subject to adverse government or legal action.

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in the Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by the Fund that the Underlying Index does not incur; the Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to Fund shareholders; tax gains or losses; differences between the amount and/or timing of withholding taxes on dividends reflected in the Underlying Index from the Fund’s obligation, if any, for foreign withholding taxes; the requirements for the Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index; and impacts to the Fund of complying with certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. Until the Fund reaches greater scale, it may experience higher tracking error than is typical for similar index ETFs. A Fund that tracks an index with exposure to non-U.S. issuers may experience higher tracking error than ETFs that do not track such indexes.

Valuation Risk. The price that the Fund could receive upon the sale (or other disposition) of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. The price received by the Fund also may differ from the value used by the Underlying Index. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares. Authorized Participants that create or redeem Fund shares on days when the Fund is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Performance Information

The performance information below illustrates how the Fund’s performance has varied over different periods and provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund has varied from one calendar year to another over the periods shown. The table compares the Fund’s performance to that of an appropriate broad-based securities market index and the Underlying Index. Returns assume the reinvestment of any dividends and distributions. The Fund’s returns reflect the impact of any agreements to waive or reimburse expenses, which would reduce performance if not in effect. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information, including the Fund’s current NAV, may be obtained by visiting www.iShares.com or by calling 1-800-iShares (1-800-474-2737) (toll free).

1Returns for net indices generally assume the reinvestment of dividends after the deduction of the maximum withholding tax in each country applicable to non-residents of the country as determined by the index provider. Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund's applicable withholding tax rates, if any.

Portfolio Managers. Jennifer Hsui, Matt Waldron, Peter Sietsema and Steven White (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Ms. Hsui, Mr. Waldron, Mr. Sietsema and Mr. White have been Portfolio Managers of the Fund since 2023, 2025, 2025 and 2025, respectively.

Purchase and Sale of Fund Shares

The Fund is an ETF. Individual shares of the Fund may only be bought and sold in the secondary market through a broker-dealer. Because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”).

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”), in which case, your distributions generally will be taxed when withdrawn.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

Principal Investment Strategies

The Fund seeks to track the investment results of the NYSE® FactSet® Global Cyber Security Index (the “Underlying Index”), which measures the performance of equity securities issued by companies involved in cyber security and technology, including cyber security hardware, software, products, and services (as determined by ICE Data Indices, LLC (the “Index Provider” or “IDI”)). The Underlying Index is composed of equity securities of companies primarily listed in one of 43 developed or emerging market countries that are the most involved in, or exposed to, (as determined by the Index Provider) a cyber hardware or cyber software and services FactSet® Revere Business Industry Classification systems (“RBICS”) sub-industry. As of July 31, 2025, there are 33 companies included in the Underlying Index. 14 of these companies are located in foreign countries, with 11 in non-U.S. developed markets and 3 in emerging markets.

The Index Provider first conducts fundamental research to establish a universe of RBICS sectors that participate in providing cyber hardware or cyber software and services, and that universe is further refined to include only the most relevant RBICS sub-sectors (as determined by the Index Provider) related to cyber hardware or cyber software activities (e.g., customer premises network security equipment producers, network security software providers, and aerospace and defense IT service providers). In constructing the Underlying Index, the Index Provider maps a universe of the most liquid and publicly-traded companies based on their primary lines of business. The Index Provider uses revenues as the key factor in determining a company’s primary line of business, by mapping a company to the sub-industry from which it derives 50% or more of its revenues. The companies within these sub-sectors are then ranked based on the data and information in their public filings and disclosures (e.g., regulatory filings, earning transcripts, etc.) to arrive at a group of the most relevant RBICS sub-industries (as determined by the Index Provider) related to cyber hardware or cyber software activities, and the Underlying Index includes the companies that derive 50% or more of their revenue from a RBICS sub-industry with exposure to the cyber hardware or cyber software and services theme, as determined by the Index Provider.

The Index Provider’s methodology does not require that at least one company from each of the sub-industries be included in the Underlying Index. In addition, companies included in the Underlying Index may also operate business lines that generate revenue in other industries.

To be included in the Underlying Index, companies must also have a float-adjusted market capitalization of $300 million or greater, but existing constituents could remain in the Underlying Index if the company's float-adjusted market capitalization is at least $225 million. In addition, companies must have a three month

average daily trading value (“ADTV”) of $2 million or greater, but existing constituents could remain in the Underlying Index if the company’s three-month ADTV is at least $1.5 million.

The Underlying Index is reconstituted annually, rebalanced semi-annually and weighted by float-adjusted market capitalization with individual constituents capped at 4% of the index. The Underlying Index includes large-, mid- and small-capitalization companies and may change over time.

As of July 31, 2025 a significant portion of the Underlying Index is represented by securities of companies in the technology industry or sector. The components of the Underlying Index are likely to change over time.

The Fund generally will invest at least 80% of its assets in the component securities of its Underlying Index and in investments that have economic characteristics that are substantially identical to the component securities of its Underlying Index (i.e., depositary receipts representing securities of the Underlying Index) and may invest up to 20% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is owned, maintained and administered by the Index Provider, which are independent of the Fund and BFA. The Index Provider determines the composition and relative

S-11

weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Summary of Principal Risks

Risk of Investing in Cybersecurity Companies. Cybersecurity companies are companies that provide products and services intended to protect the integrity of data and network operations for private and public networks, computers and mobile devices. Like other types of technology and industrials companies, cybersecurity companies are generally subject to the risks of rapidly changing technologies, short product life cycles, fierce competition, aggressive pricing and reduced profit margins, loss of patent, copyright and trademark protections, cyclical market patterns, evolving industry standards and frequent new product introductions. These companies may also be smaller and less experienced companies, with limited product lines, markets, qualified personnel or financial resources. Such companies may not be exclusively or substantially exposed to companies that provide products or services intended to protect the integrity of data and network operations, but may be exposed to the market and business risks of other companies, industries or sectors, and the Fund may be adversely affected by negative developments impacting those other companies, industries and sectors.

subordinated to preferred securities and debt in a company’s capital structure. Common stock has the lowest priority, and the greatest risk, with respect to dividends and any liquidation payments in the event of an issuer’s bankruptcy.

Index-Related Risk. The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor BFA can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Fund meeting its investment objective. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur, and the Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider and could cause the Index Provider to postpone a scheduled rebalance. This could cause the Underlying Index to vary from its normal or expected composition.

S-12

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares (including through a trading halt), losses from trading in

secondary markets, periods of high volatility, and disruptions in the process of creating and redeeming Fund shares. Any of these factors, among others, may lead to the Fund’s shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

Non-U.S. Securities Risk. Securities issued by non-U.S. issuers (including depositary receipts) are subject to different legal, regulatory, political, economic, and market risks than securities issued by U.S. issuers. These risks include greater market volatility, less market liquidity, higher transaction costs, expropriation, confiscatory taxation, adverse changes in foreign investment or currency control regulations, restrictions on the repatriation of capital, and political instability. Non-U.S. issuers may be subject to different accounting, audit and financial reporting standards than U.S. issuers, and there may be less publicly available information about non-U.S. issuers. Foreign market trading hours, different clearing and settlement procedures, and holiday schedules may limit the Fund's ability to engage in portfolio transactions. To the extent that investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund.

S-13

and the use of artificial intelligence and machine learning (“AI”), which may result in losses for the Fund and its shareholders or may impair the Fund’s operations. While the Fund’s service providers are required to have appropriate operational, information security and cybersecurity risk management policies and procedures, their methods of risk management may differ from those of the Fund. Operational and technology risks for the issuers in which the Fund invests could also result in material adverse consequences for such issuers and may cause the Fund’s investments in such issuers to lose value.

Risk of Investing in the U.S. Investing in U.S. issuers subjects the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to the U.S. Certain changes in the U.S., such as a weakening of the U.S. economy or a decline in its financial markets, may have an adverse effect on U.S. issuers.

competition, potentially rapid product obsolescence and changes in product cycles and customer preferences. They may face unexpected risks and costs associated with technological developments, such as artificial intelligence and machine learning. Technology companies also depend heavily on intellectual property rights and may be adversely affected by the loss or impairment of those rights. Technology companies may face increased government scrutiny and may be subject to adverse government or legal action.

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in the Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by the Fund that the Underlying Index does not incur; the Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to Fund shareholders; tax gains or losses; differences between the amount and/or timing of withholding taxes on dividends reflected in the Underlying Index from the Fund’s obligation, if any, for foreign withholding taxes; the requirements for the Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index; and impacts to the Fund of complying with certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. A Fund that tracks an index with exposure to non-U.S. issuers may experience higher tracking error than ETFs that do not track such indexes.

After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sales of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sales of Fund shares. As a result, Fund returns after taxes on distributions and sales of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was __% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to track the investment results of the STOXX Global Energy Storage and Materials Index (the “Underlying Index”), which measures the performance of equity securities of companies involved in energy storage solutions aiming to support the transition to a low carbon economy, including hydrogen, fuel cells, and batteries as determined by STOXX Ltd. (the “Index Provider” or “STOXX”). The Underlying Index is composed of U.S. and non-U.S. equity securities selected from the STOXX World AC

All Cap Index (the “Parent Index”). The Parent Index is composed of large-, mid- and small capitalization stocks from developed and emerging markets.

To construct the Underlying Index, the Index Provider begins with common equity securities (including depositary receipts) from the Parent Index and selects stocks belonging to the eligible country list which have an adjusted free-float market capitalization of greater than $200 million and a 3-month median daily traded value greater than $1 million. The Index Provider selects companies involved in the energy storage solutions theme using a combination of revenue exposure as defined by the FactSet Revere Business and Industry Classification System (“RBICS”), and patent exposure as assessed using EconSight’s patent data. The patent dataset provides a taxonomy that classifies patent filings around the world into specific technology categories.

The Index Provider defines two lists of eligible RBICS Level 6 sectors: Extended RBICS and Core RBICS. Extended RBICS Level 6 sectors are areas of operation which: have a direct link to the theme; are well positioned for the theme evolution, with existing

S-17

infrastructure and expertise in place; are expected to drive the innovation and viability of energy storage and hydrogen economy solutions; and/or manufacture specialty materials and chemicals for the end products, such as batteries and fuel cells. Core RBICS are a subset of Extended RBICS Level 6 sectors with a direct link to the theme. The patent exposure selection involves using EconSight’s patent data to assess a company’s patent holdings for involvement in the energy storage solutions and hydrogen economy technologies theme.

The Index Provider first selects companies with 25% or more revenue exposure from the Extended RBICS sectors to create the pre-selection list. The Index Provider further assesses the companies for their exposure to Core RBICS Level 6 sectors and their patent exposure in the areas related to energy storage and hydrogen economy technologies.

For patent exposure-based selection, the active patents for each technology are captured according to specialized patent-based analysis. The patent metrics used to assess a company's involvement in the theme are High Quality Patents and Patent Specialization. High Quality Patents is defined as the number of active patents that a company holds that fall in the top 10% in terms of patent quality within a defined technology. Patent quality is the product of citations (a measure of technology relevance) and countries covered within the patent (market coverage). Citations can be viewed as an external assessment of how competitors assessed the importance of a patent. Market coverage is seen as an internal assessment of how patents owners assessed the importance of their own invention. Both indicators are weighted so that newer citations or larger countries are more relevant. The High-Quality Patents metric allows for comparisons of patent strength between individual companies. Patent Specialization is defined as the total number of a company's active patents associated with the technologies in the theme divided by the total number of the company's active patents. It provides an indication of the importance of the technologies to the overall patent activities of the company and is a measure of technological innovation.

The Index Provider selects index constituents from the pre-selection list using a tiered approach, consisting of Tier 1a, Tier 1b and Tier 2. STOXX classifies Tier 1a companies as those that have 25% or more aggregated revenue exposure from the Core RBICS list. The Index Provider then uses High Quality Patents and Patent Specialization metrics to select securities for inclusion in Tier 1b and Tier 2. Only companies that have 50% or more revenue exposure from the Extended RBICS list are assessed for inclusion in Tier 1b. Companies included in Tier 1b must rank in the top 10% in terms of High-Quality Patent ownership and/or have Patent Specialization greater than or equal to 25%. The Index Provider then assesses all remaining companies in the pre-selection list for inclusion in Tier 2. Tier 2 includes companies ranked in the top 30% in terms of High-Quality Patent ownership and/or companies with Patent Specialization greater than or equal to 25%.

In addition, the Index Provider excludes all companies that Sustainalytics, a provider of business intelligence on environmental, social, and governance risks, identifies as: violating or being at risk of violating commonly accepted international norms and standards or other exclusion guidelines based on a company’s compliance with the United Nations Global Compact Principles, the Organisation for Economic Co-operation

and Development Guidelines for Multinational Enterprises and the UN Guiding Principles on Business and Human Rights, and their underlying conventions (collectively, “Global Standards Screening”); being involved with certain controversial weapons, small arms, oil sands, thermal coal and tobacco products; or having a Sustainalytics Controversy Rating of “Category 5 (Severe).”

After the index constituents’ initial weighting, the Index Provider applies weights against their tier group level, company level and concentration capping limits. The Index Provider applies a maximum of 20% weighting to Tier 2 companies. The component securities in the Underlying Index are weighted by float-adjusted market capitalization with individual securities capped at 8%, 6% and 4% for Tier 1a, 1b, and 2, respectively. Securities with weights greater than 4.5% will not in aggregate exceed 45% of the Underlying Index weight at rebalance. The Underlying Index is reviewed annually in June and rebalanced quarterly in September, December and March.

As of July 31, 2025, the Underlying Index comprised of securities of companies in the following countries or regions: Belgium, China, France, Germany, Japan, the Netherlands, Norway, South Korea, Switzerland, Taiwan, and the United States. The Underlying Index may include large-, mid- or small capitalization companies. As of July 31, 2025, the Underlying Index had 63 securities and a significant portion of the index constituents were represented by securities of companies in the industrials and materials industries or sectors. The components of the Underlying Index are likely to change over time.

The Fund generally will invest at least 90% of its assets in the component securities of its Underlying Index and in investments that have economic characteristics that are substantially identical to the component securities of its Underlying Index (i.e., depositary receipts representing securities of the Underlying Index) and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as

S-18

well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is sponsored by STOXX, which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Summary of Principal Risks

Energy Storage Solutions Sector Risk. The market value of securities in the energy storage solutions sector may decline for many reasons, including, among others, changes in traditional and alternative energy prices, government regulations, energy conservation efforts, and costs related to exploration, mining, and production. Companies in the energy storage solutions sector may depend largely on the availability of certain elements necessary for the production of batteries, fuel cells, and related products, which may be susceptible to fluctuations in the underlying commodities market. Such companies are also subject to risks related to the obsolescence of existing technology, competition from new market entrants, and the possibility that government subsidies for alternative energy will be eliminated.

greatest risk, with respect to dividends and any liquidation payments in the event of an issuer’s bankruptcy.

Materials Companies Risk. Materials companies may be adversely affected by volatility in commodity prices, changes in exchange rates, social and political unrest, war, depletion of resources, lower demand, overproduction, litigation and government regulations, among other factors.

China has experienced security concerns, such as terrorism and strained international relations. Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, export controls, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers in which the Fund invests. Incidents involving China’s or the region’s security may adversely affect the Chinese economy and markets and the Fund’s investments.

Risk of Investing in Japan. Investing in Japanese issuers subjects the Fund to legal, regulatory, political, economic, currency, geographic and security risks that are specific to Japan. Japan’s economy depends heavily on international trade, oil and other commodity imports, and government policy supporting its exports. Other risks facing the Japanese economy include significant public debt and deficits, currency fluctuations, and labor shortages due to an aging and declining population. Japan’s relations with its neighbors have been strained at times, which could adversely affect its markets and economy. Japan is also vulnerable to natural disasters.

Risk of Investing in the U.S. Investing in U.S. issuers subjects the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to the U.S. Certain changes in the

Principal Investment Strategies

The Fund seeks to track the investment results of the Morningstar® Exponential Technologies IndexSM (the “Underlying Index”), which measures the performance of equity securities issued by companies that Morningstar, Inc. (the “Index Provider” or “Morningstar”) has determined are positioned to experience meaningful economic benefits as a supplier or producer of promising technologies. Exponential technologies displace older technologies, create new markets, and have the potential to affect significant economic impacts.

The Underlying Index is a subset of the Morningstar Global Markets Index (the “Parent Index”). To be eligible for inclusion in the Underlying Index, constituents must be (1) companies that have an average three-month trailing daily trading volume of $2 million or greater and float market capitalization greater than $300 million and (2) companies that received a thematic exposure score of 1 or higher on at least one of the targeted themes as determined by Morningstar’s Global Equity Research team and its analysts. The Morningstar analysts perform fundamental research to assign companies within the eligible universe thematic exposure scores of 0, 1, 2, 3, or 4 based on exponential technology themes. Analysts assess whether exposure to a theme will drive a material net profit increase and then project the percentage of revenue a company will derive from exposure to each theme or subtheme over the next five years.

The Underlying Index is weighted by float-adjusted market capitalization with individual constituent weight capped at 4% and core exposure to each theme capped at 25%, where the aggregate weight of the stocks that receive a score of 2 or higher count toward core exposure to that theme. Current constituents must have an average three-month trading volume not less than $1.5 million or free-float market capitalization greater than $200 million for continued inclusion in the Underlying Index. To ensure representation across each theme, Morningstar prioritizes theme leaders for inclusion in the Underlying Index. Morningstar identifies “Theme Leaders” by prioritizing up to the top 10 scoring companies within each theme based on the following criteria listed in descending order of preference: highest thematic score, existing constituents over new constituents and smaller market capitalization over larger market capitalization. Theme Leaders are prioritized for inclusion in the Underlying Index, and remaining constituents are then ranked in descending order based on the number of themes in which a company scores a “4,” the number of themes in which a company scores a “3,” the number of themes in which a company scores a “2,” and the number of themes in which a company scores a “1,” followed by existing constituents over new constituents, and lastly, smaller market capitalization over larger market capitalization. From this

prioritization, companies are added to the list of constituents until the Underlying Index hits the targeted 200 constituents, but the Underlying Index can have more or fewer than the targeted 200. After selection and weighting of the portfolio, 90% of index weight at the time of reconstitution must have a score of 2 in at least one theme. The Underlying Index is reconstituted annually and rebalanced quarterly.

As of June 2025, Morningstar has identified seven exponential technology themes: artificial intelligence, energy innovation, fintech innovation, healthcare innovation, cybersecurity and defense tech, next gen transportation, and robotics. The themes are reviewed on an annual basis and may change over time. Morningstar’s sector strategists, directors and selection committee review the scores assigned by the Morningstar analysts and may calibrate or revise the scores to ensure consistency in scoring across analysts, sectors, geographies and themes. As a general matter, these themes focus on issuers that are either developing resources for others or are advanced in their own applications in the following areas: using artificial intelligence and its surrounding ecosystem to create new and original content; protecting organizations against cyberthreats; revolutionizing how military conflict is conducted; working to abate global climate change, reduce greenhouse gases, and develop novel energy sources; searching for and acknowledging nontraditional emerging funding sources, platforms, currency, and stored and transferred value; unlocking the human genome and developing novel therapies, devices, and diagnostics to address unmet medical needs; replacing traditional human-operated, internal combustion engine-based vehicles; and engaging with the design, construction, operation, and application of robots.

The Underlying Index includes large-, mid- and small-capitalization companies and may change over time. As of [October 31, 2025], a significant portion of the Underlying Index is represented by securities of companies in the healthcare and technology industries or sectors. The components of the Underlying Index are likely to change over time. As of [October 31, 2025], the Underlying Index consisted of securities from the following 23 countries or regions: Australia, Austria, Belgium, Canada, Chile, China, Denmark, France, Germany, India, Israel, Italy, Japan, the Netherlands, Norway, Portugal, South Korea, Spain, Sweden, Switzerland, Taiwan, the United Kingdom (the “U.K.”) and the U.S.

applicable to sectors other than the exponential technology theme for which they are chosen, and the securities issued by these companies may underperform the securities of other companies that are primarily focused on a particular theme. The Fund may invest in a company that does not currently derive any revenue from exponential technologies, and there is no assurance that a company will derive any revenue from exponential technologies in the future. An exponential technology may constitute a small portion of a company’s overall business. As a result, the success of an exponential technology may not affect the value of the equity securities issued by the company.

S-27

Healthcare Companies Risk. The profitability of healthcare companies may be adversely affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, the protection and expiration of patents, limited product lines, supply chain issues, labor shortages and product liability claims, among other factors.

region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s investments. In addition, developed countries may be adversely impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.

Technology Companies Risk. Technology companies and companies that rely heavily on technological advances may have limited product lines, markets, financial resources, supply chains and personnel. These companies typically face intense competition, potentially rapid product obsolescence and changes in product cycles and customer preferences. They may face unexpected risks and costs associated with technological developments, such as artificial intelligence and machine learning. Technology companies also depend heavily on intellectual property rights and may be adversely affected by the loss or impairment of those rights. Technology companies may face increased government scrutiny and may be subject to adverse government or legal action.

Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. A Fund that tracks an index with exposure to non-U.S. issuers may experience higher tracking error than ETFs that do not track such indexes.

Principal Investment Strategies

The Fund seeks to track the investment results of the NYSE® FactSet® Global Genomics and Immuno Biopharma Index (the “Underlying Index”), which measures the performance of equity securities issued by companies in the biopharmaceutical and healthcare equipment and services industries that could benefit from the long-term growth and innovation in genomics, immunology and bioengineering, as determined by ICE Data Indices, LLC or its affiliates (the “Index Provider” or “IDI”).

The Underlying Index is composed of equity securities primarily listed in one of 42 developed and emerging market countries. Companies must have equal to or greater than 50% of their revenue from one or more selected Level 6 industries, as defined by the FactSet Revere Business Industry Classification System (“RBICS”), which includes biopharmaceutical industries, healthcare equipment industries, and healthcare services industries. Companies selected from these industries are assigned a Genomics and Immuno Biopharma Composite Relationship Keyword score (a “Score”).

To compute a Score for a company, the Index Provider searches the FactSet Supply Chain Relationships database for keywords related to genomics and immunology products and technologies. A Score is assigned to each company identified in the database search based on the number of relationships a company has to genomics and immunology products. The top 50 companies with the highest Scores are selected for inclusion in the Underlying Index.

The Underlying Index is reviewed and reconstituted annually in December. Constituent weights of the Underlying Index are determined according to float-adjusted market capitalization and are rebalanced semi-annually. Individual constituents are capped at 4% of the Underlying Index. The aggregate weight of component securities classified in the RBICS Level 6 industry Diversified Biopharmaceuticals is capped at 25%, with excess weight redistributed proportionately among remaining constituents.

The Underlying Index includes large-, mid- and small-capitalization companies and may change over time. As of July 31, 2025, a significant portion of the Underlying Index is represented by securities of companies in the healthcare industry or sector. The components of the Underlying Index are likely to change over time.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the

risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by aiming to keep portfolio turnover low in comparison to actively managed investment companies.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is owned, maintained and administered by the Index Provider, which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

risk is difficult to predict and may change over time. You should review each risk factor carefully.

S-35

shareholders would not redeem their investment. Redemptions of a large number of Fund shares could require the Fund to dispose of assets to meet the redemption requests, which can accelerate the realization of taxable income and/or capital gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such year. In some circumstances, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. These large redemptions may also force the Fund to sell portfolio securities or other assets when it might not otherwise do so, which may negatively impact the Fund’s NAV, increase the Fund’s brokerage costs and/or have a material effect on the market price of Fund shares.

of a small number of issuers or counterparties, which may lead to more volatility in the Fund’s NAV.

S-36

addition, developed countries may be adversely impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in the Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by the Fund that the Underlying Index does not incur; the Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by the Fund or distributions paid to Fund shareholders; tax gains or losses; differences between the amount and/or timing of withholding taxes on dividends reflected in the Underlying Index from the Fund’s obligation, if any, for foreign withholding taxes; the requirements for the Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index; and impacts to the Fund of complying with certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. A Fund that tracks an index with exposure to non-U.S. issuers may experience higher tracking error than ETFs that do not track such indexes.

The Fund seeks to track the investment results of the NYSE® FactSet® Global Neuro Biopharma and MedTech Index (the “Underlying Index”), which measures the performance of equity securities of companies that are involved in the research, development or manufacturing of neurology biopharmaceuticals or neurological devices, as determined by ICE Data Indices, LLC or its affiliates (the “Index Provider” or “IDI”).

To be eligible for the Underlying Index, an equity security must (i) be listed in one of 44 developed and emerging market countries or regions, (ii) have a float-adjusted market capitalization of at least $100 million and (iii) have a three-month average daily trading value (“ADTV”) of at least $1 million. Existing constituents may remain in the Underlying Index with a float-adjusted market capitalization of at least $75 million and a three-month ADTV of at least $750,000 at each index reconstitution and rebalance.

The Underlying Index is composed of securities that are classified within one of two sub-industries defined by the FactSet Revere Business Industry Classification System (“RBICS”): Neurology Biopharmaceuticals and Neurology Devices. For a company to be included in either sub-industry, the sub-industry must represent at least 50% of the company’s annual revenues or, for pre-revenue companies, the company’s primary business as indicated by its product pipeline, each as determined by the Index Provider.

The methodology does not require that at least one company from each of the sub-industries be included in the Underlying Index. Constituents may also operate business lines that generate revenue in other industries. The Index Provider seeks to exclude companies whose business description, trade names or supply chain relationships indicate an involvement with psychedelics or cannabis, as determined by the Index Provider based on an analysis using FactSet keyword data.

The Underlying Index is reviewed and reconstituted in March and September and rebalanced quarterly. Constituent weights of the Underlying Index are determined according to float-adjusted market capitalization, and individual constituents are capped at 4% of the Underlying Index at each index reconstitution and rebalance.

As of July 31, 2025, a significant portion of the Underlying Index is represented by securities of companies in the healthcare, neurology biopharmaceuticals and neurology devices industries or sectors. As of July 31, 2025, the Underlying Index consisted of securities from the following countries or regions: Canada, Denmark, France, Hong Kong, Ireland, Japan, the Netherlands, New Zealand, South Korea, Sweden, Switzerland, and the U.S. The Underlying Index includes large-, mid- and small-capitalization companies, and its components are likely to change over time.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Neuroscience Companies Risk. Neuroscience companies are often subject to the potential or actual performance of a limited number of products or technologies and may be greatly affected if any of their products or technologies proves to be, among other things, unsafe, ineffective or unprofitable. Neuroscience companies may not be able to capitalize on such products or technologies. Neuroscience companies may face political, legal or regulatory challenges or constraints from competitors, industry groups or local and national governments. They are also subject to product liability claims, patent expirations and intense competition, which may affect the value of their equity securities. Neuroscience companies may be thinly capitalized, and their equity securities may be more volatile than companies with greater capitalizations. Neuroscience companies are also susceptible to the market and business risks of related industries, such as the biotechnology, pharmaceutical and health care equipment industries.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole,

S-43

to the extent that the Fund’s investments are concentrated in the securities or other assets of one or more issuers, countries or other geographic units, markets, industries, project types, or asset classes.

intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

Reliance on Trading Partners Risk. The Fund invests in countries or regions whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an

S-44

adverse impact on the Fund's investments. Through its holdings of securities of certain issuers, the Fund is specifically exposed to Asian Economic Risk, European Economic Risk and North American Economic Risk.

Any resulting liquidation of the Fund could lead to elevated transaction costs for the Fund and negative tax consequences for its shareholders.

The Fund seeks to track the investment results of the NYSE® FactSet® Global Autonomous Driving and Electric Vehicle Index (the “Underlying Index”), which measures the performance of equity securities issued by companies that produce autonomous driving vehicles, electric vehicles, batteries for electric vehicles, or technologies related to such products. The determination of inclusion in the Underlying Index is made by ICE Data Indices, LLC, or its affiliates (the “Index Provider” or “IDI”).

The Underlying Index is composed of equity securities of companies listed in one of 43 developed or emerging market countries that derive a certain specified percentage of their revenue from selected autonomous or electric vehicle-related industries, as defined by IDI. Companies are selected using a combination of revenue exposure and supply-chain relationship data, as defined by the FactSet Revere Business Industry Classification System (“RBICS”). Companies in these autonomous or electric vehicle related industries include (i) autonomous and electric vehicle manufacturers, (ii) autonomous software and electronics companies, (iii) autonomous and electric driving technology companies, (iv) electric vehicle battery producers, (v) electric vehicle battery materials producers, and (vi) electric vehicle charging companies.

Based on the Index Provider’s methodology and as determined by the Index Provider, companies included in the Underlying Index include:

(1) companies that generate 50% or more of their revenue from the manufacturing of autonomous or electric vehicles;

(2) companies that generate 50% or more of their revenue from electric vehicle battery manufacturing or companies that generate 50% or more of their revenue from heavy-duty and high-end battery manufacturing or traditional vehicle batteries and have products in electric vehicle batteries;

(3) companies that generate 50% or more of their revenue in aggregate from lithium mining or manufacturing and supply to car manufacturers or companies that have revenue generated from electric vehicle battery manufacturing;

(4) companies that generate 50% or more of their revenue from electric vehicle charging stations or battery charging equipment manufacturing and have a business description which includes “electric vehicle”;

(5) companies that generate 50% or more of their revenue from autonomous software or electronics (“autonomous software and electronics companies”); and

(6) companies that in aggregate generate 50% or more of their revenue from 8 selected automotive value chain industries and

are a supplier to at least one autonomous or electric vehicle manufacturing company (“autonomous and electric driving technology companies”).

The component securities of the Underlying Index are weighted by float adjusted market capitalization with individual securities capped at 4%.

The weight of autonomous software and electronics companies and autonomous and electric driving technology companies are in aggregate capped at 25%.

The Underlying Index will be reviewed and reconstituted annually in December each year. Constituent weights of the Underlying Index are rebalanced semi-annually. The Underlying Index includes large-, mid- and small-capitalization companies and may change over time.

As of July 31, 2025, a significant portion of the Underlying Index is represented by securities of companies in the automotive, consumer good and services, industrials, materials and technology industries or sectors. As of July 31, 2025, the Underlying Index was comprised of 47 components. The components of the Underlying Index are likely to change over time. The Underlying Index includes technology companies that are involved in or exposed to, self-driving or electric vehicle-related industries. These companies may not be exclusively or substantially exposed to the information technology industry and may be classified in the consumer discretionary, industrials or materials industries or sectors.

which BFA believes will help the Fund track the Underlying Index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Electric Vehicles Sector Risk. Companies involved in, or exposed to, electric vehicles-related businesses may have limited product lines, markets, financial resources or personnel. Electric vehicle technology is a relatively new technology and is subject to risks associated with a developing industry. These risks include intense competition, delays or other complications in connection with production, rapid product obsolescence, increased government regulation and market volatility. Many companies involved in, or exposed to, electric vehicles-related businesses depend significantly on retaining and growing the consumer base of their products and services. Such companies may not be exclusively or substantially exposed to the electric vehicles sector, but may be substantially exposed to the market and business risks of other industries or sectors, and the Fund may be adversely affected by negative developments impacting those companies, industries or sectors. Electric vehicle companies currently benefit from certain government subsidiaries, policies and economic incentives, which may be reduced or eliminated in the future.

In addition, these companies may be adversely affected by loss or impairment of intellectual property rights. There can be no assurance that companies involved in electric vehicle technology will be able to successfully protect their intellectual property to

prevent the misappropriation of their technology, or that competitors will not develop technology that is substantially similar or superior to such companies’ technology. Electric vehicle companies typically engage in significant amounts of spending on research and development, and there is no guarantee that the products or services produced by these companies will be successful. These companies are also susceptible to litigation based on product liability claims and can be significantly affected by insurance costs. In addition, electric vehicle companies may not maintain as much insurance coverage as other types of companies and any insurance coverage may not be sufficient to cover all losses or claims.

In addition, these companies may be adversely affected by loss or impairment of intellectual property rights. There can be no assurance that companies involved in autonomous driving technology will be able to successfully protect their intellectual property to prevent the misappropriation of their technology, or that competitors will not develop technology that is substantially similar or superior to such companies’ technology. Autonomous driving companies typically engage in significant amounts of spending on research and development, and there is no guarantee that the products or services produced by these companies will be successful. These companies are also susceptible to litigation based on product liability claims and can be significantly affected by insurance costs. In addition, autonomous driving companies may not maintain as much insurance coverage as other types of companies and any insurance coverage may not be sufficient to cover all losses or claims.

Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other

S-50

asset classes. The value of a security may decline for a number of reasons that may directly relate to the issuer as well as due to general industry or market conditions. Common stock is subordinated to preferred securities and debt in a company’s capital structure. Common stock has the lowest priority, and the greatest risk, with respect to dividends and any liquidation payments in the event of an issuer’s bankruptcy.

Automotive Sub-Industry Risk. The automotive sub-industry can be highly cyclical and companies in the automotive sub-industry may suffer periodic losses. Among other things, the automotive sub-industry is susceptible to labor disputes, economic downturns and increase in component and material prices. As a result, such

risks, among others, may adversely affect the value of the Fund’s investments.

S-51

of assets to meet the redemption requests, which can accelerate the realization of taxable income and/or capital gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such year. In some circumstances, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. These large redemptions may also force the Fund to sell portfolio securities or other assets when it might not otherwise do so, which may negatively impact the Fund’s NAV, increase the Fund’s brokerage costs and/or have a material effect on the market price of Fund shares.

military conflicts in response to such events, may disrupt China’s economy and markets and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher inflation.

experienced security concerns, such as war, terrorism and strained international relations. Incidents involving a country’s or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s investments. In addition, developed countries may be adversely impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory, currency and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’s ownership rights in its portfolio securities as a result of the system of share registration and custody in Russia. Governments, including the U.S., the U.K., the E.U., and many other countries have imposed economic sanctions on certain Russian individuals and Russian corporate and banking entities, and jurisdictions may also institute broader sanctions on Russia. Russia has issued a number of countersanctions, some of which restrict the distribution of profits by limited liability companies (e.g., dividends), and prohibit Russian persons from entering into transactions with designated persons from “unfriendly states” as well as the export of raw materials or other products from Russia to certain sanctioned persons.

Russia launched a large-scale invasion of Ukraine on February 24, 2022. The extent and duration of the military action, resulting sanctions and resulting future market disruptions, including declines in its stock markets and the value of the ruble against the U.S. dollar, are impossible to predict, but could be significant. Disruptions caused by Russian military action or other actions (including cyberattacks and espionage) or resulting actual and threatened responses to such activity, including purchasing and financing restrictions, boycotts or changes in consumer or purchaser preferences, sanctions, import and export restrictions, tariffs or cyberattacks on the Russian government, Russian companies, or Russian individuals, including politicians, may impact Russia’s economy and Russian companies in which the Fund invests. Actual and threatened responses to Russian military action may also impact the markets for certain Russian commodities, such as oil and natural gas, as well as other sectors of the Russian economy, and are likely to have collateral impacts on such sectors globally. Russian companies may be unable to pay dividends and, if they pay dividends, the Fund may be unable to receive them. As a result of sanctions, the Fund is currently restricted from trading in Russian securities, including those in its portfolio, and the Underlying Index has removed Russian securities. It is unknown when, or if, sanctions may be lifted or the Fund’s ability to trade in Russian securities will resume.

S-53

also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

amount and/or timing of withholding taxes on dividends reflected in the Underlying Index from the Fund’s obligation, if any, for foreign withholding taxes; the requirements for the Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index; and impacts to the Fund of complying with certain regulatory requirements or limits. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. A Fund that tracks an index with exposure to non-U.S. issuers may experience higher tracking error than ETFs that do not track such indexes.

Principal Investment Strategies

The Fund seeks to track the investment results of the NYSE® FactSet® U.S. Tech Breakthrough Index (the “Underlying Index”), which measures the performance of U.S. listed companies engaged in cutting edge research and development of products and services in the areas of robotics and artificial intelligence, cyber security, cloud and data tech, financial technology, and genomics and immunology (as determined by ICE Data Indices, LLC or its affiliates) (the “Index Provider” or “IDI”). Companies selected must belong to one of the five aforementioned thematic segments and must meet the eligibility requirements of that segment to which the company is classified as defined by the FactSet Revere Business Industry Classification Systems (“RBICS”).

The eligibility requirements for the Robotics and Artificial Intelligence theme are securities with a minimum float-adjusted market capitalization of $500 million or greater, and a three-month average daily trading value (“ADTV”) of $2 million or greater on the Reference Date. “Reference Date” means the date on which data is used to reconstitute the Underlying Index, which is as of the close of business on the first Friday in December, and the date on which data is used to rebalance the Underling Index, which is as of the close of business on the first Friday in June and December. Companies must also be classified as (1) deriving 50% or more revenues from one of 22 RBICS Focus Level 6 industries related to Robotics and Artificial Intelligence, or (2) have a 20% or more market share or generate $1 billion or more in absolute annual revenues from one of the 22 aforementioned RBICS Level 6 industry classifications.

The eligibility requirements for the Cyber Security theme are securities with a minimum float-adjusted market capitalization of $300 million or greater, and a three-month ADTV of $2 million or greater on the Reference Date. Companies must also be classified as deriving 50% or more revenues from one of 12 RBICS Focus Level 6 industries related to Cyber Security, with additional screens applied to companies classified to “Multi-Type Home and Office Software.”

The eligibility requirements for the Cloud and Data Tech theme are securities with a minimum float-adjusted market capitalization of $300 million or greater, and a three-month ADTV of $2 million or greater on the Reference Date. Companies must also be classified as deriving 50% or more revenues from one of 20 RBICS Focus Level 6 industries related to Cloud and Data Tech, with additional screens applied to companies classified to 4 RBICS Focus Level 6 industries: “Industrial and Warehouse Equity REITs”, “Multi-Type Equity REITs”, “General and Mixed-Type Software” or “General Information Technology (IT) Consulting.”

The eligibility requirements for the Financial Technology theme are securities with a minimum float-adjusted market capitalization of $300 million or greater, and a three-month ADTV of $2 million or greater on the Reference Date. Companies must also be classified as deriving 50% or more revenues from one of 17 RBICS Focus Level 6 industries related to Financial Technology.

The eligibility requirements for the Genomics and Immunology theme are securities with a minimum float-adjusted market capitalization of $300 million or greater, and a three-month ADTV of $2 million or greater on the Reference Date. Companies must also be classified as deriving 50% or more revenues from one of 60 RBICS Focus Level 6 industries related to Genomics and Immunology. A Genomics and Immuno Biopharmaceutical composite relationship keyword score is then calculated for each selected company based on the number of relationships mentioning keywords related to Genomics and Immuno Biopharmaceutical products and technologies. Companies are ranked in descending order and the top 50 ranked companies are selected for the Genomics and Immunology theme.

All eligible securities that have been assigned to one of the five aforementioned themes must also be primarily listed on one of the four U.S. exchanges: NYSE, NYSE American, Nasdaq or CBOE. All eligible issuers must also be incorporated in the U.S. Finally, all remaining securities must also have a minimum float-adjusted market capitalization of $500 million or greater, and a three-month ADTV of $2 million or greater on the Reference Date.

The Underlying Index is weighted according to the component stocks’ float-adjusted market capitalization by dividing their individual float-adjusted market capitalization by the total float-adjusted market capitalization of all constituents, with individual security weights capped at 4% and individual thematic segment weights maintained at a minimum of 10%. The Underlying Index is reviewed and reconstituted annually in December. Constituent weights of the Underlying Index are rebalanced semiannually. The Underlying Index includes large-, mid- and small-capitalization companies and may change over time. In addition, certain companies included in the Underlying Index may also operate in business lines other than the theme to which they are assigned that also generate revenue in other industries. As of July 31, 2025, a significant portion of the Underlying Index is represented by securities of companies in the technology industry or sector. The components of the Underlying Index are likely to change over time.

The Fund generally will invest at least 80% of its assets in the component securities of its Underlying Index and may invest up to 20% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not

S-58

included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

performance may also be impacted if securities that are not related to the theme or sub-theme are included in the Underlying Index.

S-59

companies may not be exclusively or substantially exposed to the cloud-based computing and data storage-related businesses, but may be exposed, directly or indirectly, to the market and business risks of other companies, industries or sectors. In addition, these companies may depend on intellectual property rights to protect their computing and storage services, which may be difficult to prevent the misappropriation of, and are susceptible to competitors that may develop substantially similar or superior technology.

Cloud-based computing and data storage companies also depend on the services of third parties, which, if interrupted, may impact their products and services. These companies are also potential targets for cyberattacks, which may have a materially adverse impact on the performance of these companies. Cloud-based computing may face increasing regulatory scrutiny and legal liability, which may limit the development of this technology and impede the growth of companies that develop or use this technology. Similarly, the collection of data from consumers and other sources, and storage of that data, may face increased scrutiny as regulators consider how data may be collected, stored, safeguarded and used.

Risk of Investing in Cloud Computing Companies. Cloud computing companies include companies that provide remote computation, software, data access and storage services. The risks related to investing in such companies include disruption in service caused by hardware or software failure, interruptions or delays in service by third-party data center hosting facilities and maintenance providers, security breaches involving certain private, sensitive, proprietary and confidential information managed and transmitted by cloud computing companies, and privacy concerns and laws, evolving Internet regulation and other foreign or domestic regulations that may limit or otherwise affect the operations of such companies. Also, the business models employed by the companies in the cloud computing industry may not prove to be successful.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual shares of the Fund may only be bought and sold in the secondary market through a broker-dealer. Because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”).

On September 22, 2025, the name of the Fund changed from the iShares Exponential Technologies ETF to the iShares Future Exponential Technologies ETF.

ETFs are funds that trade like other publicly traded securities. Shares of each Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day. The market price for a share of a Fund may be different from the Fund’s most recent NAV.

Each Fund invests in a particular segment of the markets for securities and other instruments (as applicable) and is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in a Fund should not constitute a complete investment program. An investment in a Fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation, any other government agency, BFA or any of BFA’s affiliates.

Index Funds

A share of a Fund represents an ownership interest in an underlying portfolio of securities and other instruments (as applicable) that is intended to track the Fund’s Underlying Index. An index is a financial calculation, based on a grouping of financial instruments, and is not an investment product, while each Fund is an actual investment portfolio. The performance of a Fund and that of its Underlying Index may vary for a number of reasons, including transaction costs, asset or currency valuations, corporate actions, timing variances and differences between the composition of a Fund’s portfolio and that of the Underlying Index resulting from the Fund’s use of representative sampling or from legal restrictions (such as diversification requirements) that apply to the Fund but not to its Underlying Index.

From time to time, the provider of the Underlying Index (“Index Provider”) may make changes to the index methodology or other adjustments to a Fund’s Underlying Index. Unless otherwise determined by BFA, any such change will be reflected in the calculation of the Underlying Index’s performance on a going-forward basis after the effective date of such change. Therefore, the performance of the Underlying Index that is shown for periods prior to the effective date of any such change generally will not be recalculated or restated to reflect the change.

BFA uses a representative sampling indexing strategy to manage the Funds. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to that of the applicable underlying index. Because the Funds use representative sampling, they can be expected to have a larger tracking error than if they used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

Borrowing

Each Fund listed below may borrow as a temporary measure for extraordinary or emergency purposes, including to meet redemptions or to facilitate the settlement of securities or other transactions. Each Fund does not intend to borrow money in order to leverage its portfolio.

Additional Index Information – iShares Breakthrough Environmental Solutions ETF

Categorical exclusions include any issuer that has any involvement in:

■

the sale of assault or non-assault weapons;

■

the manufacture of small arms components;

■

the production of tobacco products; and

■

controversial and nuclear weapons (e.g., antipersonnel mines, biological and chemical weapons, depleted uranium, nuclear weapons, or white phosphorus).

Additionally, the Index Provider categorically excludes companies that it determines are involved in controversies related to the ten United Nations Global Compact (“UNGC”) principles, which are classified into four categories: human rights, labor, environment and anti-corruption. The Index Provider relies on the assessment of a third party data provider, Sustainalytics, to determine whether an issuer has violated the principles of the UNGC. To make this determination, Sustainalytics analyzes publicly reported allegations of adverse impacts caused by businesses and provides assessments based on the UNGC principles, categorizing those businesses as either “Non-compliant,”“Watchlist,” or “Compliant.” Companies that Sustainalytics determines are Non-Compliant typically are causing or contributing to severe and/or systemic violations of international norms and are not acting in accordance with the UNGC principles and their associated standards, conventions, and treaties. All companies that Sustainalytics determines to be Non-Compliant are excluded from the Underlying Index.

Further, the Index Provider categorically excludes companies that Sustainalytics has assigned a controversy score of 5 (indicating the company experienced an event with a severe impact on the environment and society), or companies which have not been assigned a controversy score. Sustainalytics assesses companies’ involvement in “incidents” with negative environmental, social, and governance implications and assigns a “controversy score”, which reflects a company’s level of involvement in issues and how it manages these issues. An incident is a company activity with unintended and/or undesired negative environmental and/or social impacts on stakeholders. Incidents are primarily assessed based on the negative environmental and/or social impact of the company activity as well as the reputational risk that this activity poses to the company and scored on a scale of 1 to 10. Incident scores serve as a guide to help Sustainalytics analysts determine the event rating. “Events” are series of isolated or related incidents that pertain to the same ESG issues. An event is assessed on a scale of 5 levels, with level 5 being severe, and the assessment takes into account the score of each incident

Additional Information About the Funds' Risks

Each Fund is subject to various risks, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. Each Fund discloses its portfolio holdings daily at www.iShares.com. You could lose all or part of your investment in a Fund, which could underperform other investments. The table below identifies the principal and other (non-principal) risks that apply to each Fund. A Fund that invests in an underlying fund (“Underlying Fund”) also may be indirectly exposed to these risks through such investment. A description of each risk is provided after the table.

Asian Economic Risk. Certain Asian economies have experienced rapid growth and industrialization in recent years, but there is no assurance that this growth rate will be maintained. Other Asian economies have experienced high inflation, high unemployment, currency devaluations and restrictions, and over-extension of credit. Geopolitical hostility, political instability, and economic or environmental events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia. An adverse event in the Asian markets may have a significant adverse effect on some or all of the economies of the countries in which a Fund invests. Because many Asian countries depend significantly on international trade, shifts in relationships with key trading partners, such as China and the U.S., may have a region-wide economic impact. Strains in these relations could adversely affect Asian issuers that rely on the U.S. or China for trade and the region as a whole. A shift towards protectionist policies by these countries or other key trading partners could suppress Asia’s exports and reduce foreign investment in the region.

Many Asian countries are subject to political risk, including political instability, corruption and regional conflicts. North Korea and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. China has a complex territorial dispute regarding the sovereignty of Taiwan and has pledged to take control of Taiwan, including by force if necessary. Continuing hostility between China and Taiwan may have an adverse impact on economies throughout the region and on the value of a Fund’s investments, may cause a suspension in a Fund’s ability to trade in certain securities or other assets, or may otherwise make such investments impracticable or impossible. Frictions between China and the Philippines in the South China Sea pose a risk of escalation potentially leading to military conflict. In addition, many Asian countries are subject to social and labor risks associated with demands for improved political, economic and social conditions. These risks, among others, may adversely affect the value of a Fund’s investments with exposure to Asia.

Asset Class Risk. The securities and other assets in a Fund’s portfolio or, if applicable, its Underlying Index may underperform in comparison to indexes that track, or assets that represent, other countries or geographic units, industries, markets, market segments, or asset classes. Various types of securities, other assets and indexes may experience cycles of outperformance and underperformance in comparison to financial markets generally. This divergence may be due to a number of factors including, among other things, inflation, interest rates, productivity, global demand for local products or resources, and regulation and governmental controls. This may cause a Fund to underperform other investment vehicles that invest in different asset classes.

Assets Under Management (AUM) Risk. From time to time, an Authorized Participant, a third-party investor, a Fund’s adviser, an affiliate of a Fund’s adviser, or another fund may invest in a Fund and hold its investment for a specific period of time to allow the Fund to achieve

size or scale. There can be no assurance that any such entity would not redeem its investment or that the size of the Fund would be maintained at such levels, which could negatively impact the Fund.

Australasian Economic Risk. The economies of Australasia, which include Australia and New Zealand, depend on exports from the energy, agricultural and mining sectors and, as a result, are susceptible to fluctuations in the commodity markets. These economies also increasingly depend on their growing service industries. The Australasian economies depend on the economies of their key trading partners, which include China, Japan, South Korea, the U.S. and certain European countries. Reduced spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may have an adverse impact on some or all of the Australasian economies. Economic events in key trading countries can have a significant effect on the Australasian economies.

Other risks to Australasian countries include natural disasters that may occur in the region (e.g., droughts, earthquakes, fires, tsunamis) and national or regional security concerns (e.g., terrorism, war, strained international relations). Any such event may adversely affect the Australasian economies, financial markets or issuers of securities, causing an adverse impact on the value of a Fund’s investments.

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with a Fund. There are a limited number of institutions that may act as Authorized Participants for the Fund, including on an agency basis on behalf of other market participants. No Authorized Participant is obligated to engage in creation or redemption transactions. To the extent that Authorized Participants exit the business or do not place creation or redemption orders for a Fund and no other Authorized Participant places orders, Fund shares are more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for a Fund that invests in securities issued by non-U.S. issuers or instruments with lower trading volume. Such assets often entail greater settlement and operational complexity and higher capital costs for Authorized Participants, which may limit the number of Authorized Participants that engage with the Fund.

Automotive Sub-Industry Risk. The automotive sub-industry can be highly cyclical and companies in this sub-industry may suffer periodic operating losses. Companies in this sub-industry face intense competition, both domestically and internationally, which may have an adverse effect on their profitability. The sub-industry can be significantly affected by labor relations, fluctuating component and material prices, product recalls, domestic and international economic downturns and consumer demands. Government regulation and increased competition may also negatively affect automotive manufacturers. Some automotive manufacturers are small or financially vulnerable and can be non-diversified in both product line and consumer base, and may be more susceptible to adverse developments. The automotive sub-industry is currently experiencing a global semiconductor supply shortage, which has affected suppliers that incorporate semiconductors into the parts they supply to customers in the automotive sub-industry. As a result, companies in the automotive sub-industry may experience decreased sales due to lost or delayed production volume, which may in turn adversely affect the performance of securities of issuers in the automotive sub-industry.

Autonomous Driving Sector Risk. Companies involved in, or exposed to, autonomous driving-related businesses may have limited product lines, markets, financial resources or personnel. Autonomous driving technology is a relatively new technology and is subject to risks associated with a developing industry. These risks include intense competition, delays or other complications in connection with production, rapid product obsolescence, increased government regulation and market volatility. As a new technology, any product defects, delays in the implementation of full autonomous driving or legal restrictions could have an adverse effect on the businesses of autonomous driving companies. In addition, certain autonomous driving companies are dependent upon the services of certain key personnel and are susceptible to instability and volatility caused by the actions of or changes to key personnel. Autonomous vehicle technology could face increasing regulatory scrutiny in the future, which may limit the development of this technology and impede the growth of companies that develop and/or utilize this technology. In addition, existing regulations that may apply to autonomous vehicle technology continue to rapidly change, which could adversely affect the businesses of autonomous driving companies. The prices of securities of companies involved in a new industry may be more volatile than those in more mature industries.

Many companies involved in, or exposed to, autonomous driving-related businesses may not be exclusively or substantially exposed to the autonomous driving sector, but may be substantially exposed to the market and business risks of other industries or sectors, and the Fund may be adversely affected by negative developments impacting those companies, industries or sectors. In addition, these companies may be adversely affected by loss or impairment of intellectual property rights. There can be no assurance that companies involved in autonomous driving technology will be able to successfully protect their intellectual property to prevent the misappropriation of their technology, or that competitors will not develop technology that is substantially similar or superior to such companies’ technology.

Autonomous driving companies typically engage in significant amounts of spending on research and development, and there is no guarantee that the products or services produced by these companies will be successful. These companies are also susceptible to litigation based on product liability claims and can be significantly affected by insurance costs. In addition, autonomous driving companies may not maintain as much insurance coverage as other types of companies and any insurance coverage may not be sufficient to cover all losses or claims. A loss that is uninsured or that exceeds policy limits may require a company to pay substantial amounts, which could adversely affect the financial condition of the company.

Autonomous driving vehicle technology companies could be adversely affected by cybersecurity breaches, traffic accidents related to autonomous vehicles, and other issues that could lead to litigation and/or additional regulation. Specifically, autonomous driving vehicles may contain complex information technology systems designed with built-in data connectivity to accept and install periodic remote updates,

which could be subject to risks associated with the unauthorized access of and control over the vehicles by third parties. Any cyber-attack or data breach of the information technology systems could negatively affect the brand, reputation and financial condition of the company.

Biopharmaceuticals Industry Risk. The biopharmaceutical industry includes companies from each of the biotechnology, pharmaceutical and life sciences industries. Such companies are engaged in the research and development of a variety of products and services including but not limited to products and services for use in internal medicine, vaccines, oncology, immunology, rare diseases and consumer healthcare. Biopharmaceutical companies may also engage in product research and development related to genomics, which generally refers to the use of genomic information in the provision of medical care. Set forth below are specific risk considerations with respect to each of the biotechnology, life sciences and pharmaceutical industries, which includes those companies that could benefit from long-term growth and innovation in genomics, immunology and bioengineering. Such risks collectively represent the risks applicable to the biopharmaceutical industry. Companies in the biopharmaceutical industry may be highly volatile for the reasons discussed below.

Biotechnology Industry Risk. Companies in the biotechnology industry spend heavily on research and development, and their products or services may not prove commercially successful or may become obsolete quickly. The biotechnology industry is subject to a significant amount of governmental regulation, and changes in governmental policies and the need for regulatory approvals may have a material adverse effect on this industry. Companies in the biotechnology industry are subject to risks of new technologies and competitive pressures and are heavily dependent on patents and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Pharmaceuticals Industry Risk. Companies in the pharmaceuticals industry are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. The profitability of some companies in the pharmaceuticals industry may be dependent on a relatively limited number of products. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the pharmaceuticals industry are subject to government approvals, regulation and reimbursement rates. The process of obtaining government approvals may be long and costly. Many companies in the pharmaceuticals industry are heavily dependent on patents and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Companies in the pharmaceutical industry may be subject to extensive litigation based on product liability and similar claims. Pharmaceutical companies may also be dependent on one or more wholesalers for product distribution. If a significant pharmaceutical wholesaler should encounter financial or other difficulties, a pharmaceutical company might be unable to collect all or any of the amounts that the wholesaler owes such company. In addition, consolidation and integration of pharmacy chains and wholesalers may increase competitive and pricing pressures on pharmaceutical companies.

Life Sciences Industry Risk. The life sciences industry is composed primarily of companies enabling drug discovery, development and production by providing analytical tools, instruments, consumables and supplies, clinical trial services and contract research services. Companies in the life sciences industry primarily service the pharmaceutical and biotechnology industries. The life sciences industry is heavily influenced by technology, government funding, government regulation, efforts by governments, healthcare providers’ and health plans’ efforts to reduce costs, changing consumer demographics and intellectual property rights, among other factors. Regulations may restrict a company’s ability to pursue or use potentially profitable research. The products and services of life sciences companies may experience rapid obsolescence due to a number of factors, including technological advances, supply chain issues or the expiration of their patents. The life sciences industry is highly competitive, and companies in the life sciences industry often invest in new and uncertain innovations. The success of such companies may depend upon a relatively small number of products or services with long development cycles and large capital requirements that have a high chance of failure. In addition, changes in patent protection, government approvals, regulations or funding, patent infringement or medical litigation may adversely affect the value of such companies.

Borrowing Risk. Borrowing may exaggerate changes in a Fund’s NAV and in the return on its portfolio. A Fund that borrows will incur interest expenses and other fees, which may reduce the Fund’s return. Borrowing may also cause a Fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations.

Breakthrough Innovations and New Technologies Risk. Breakthrough innovations and new technologies are products or services that fundamentally change the dynamics of an industry or market. The Fund's holdings may include equity securities of operating companies that focus on or have exposure to a wide variety of industries, and the economic success of certain of these companies may not be significantly tied to breakthrough innovations and new technologies. Companies involved in breakthrough innovations and new technologies may have limited product lines, markets, financial resources or personnel that face intense competition and potentially rapid product obsolescence. These companies may not be exclusively or substantially exposed to breakthrough innovations and new technologies, but may be exposed, directly or indirectly, to the market and business risks of other companies, industries or sectors. In addition, these companies may depend on intellectual property or patent rights to protect their innovations or new technologies, which may be difficult to prevent the misappropriation of, and are susceptible to competitors that may develop substantially similar or superior products or services.

Close-Out Risk for Qualified Financial Contracts. Regulations adopted by global prudential regulators require counterparties that are part of U.S. or foreign global systemically important banking organizations to include contractual restrictions on close-out and cross-default in agreements relating to qualified financial contracts. Qualified financial contracts include agreements relating to swaps, currency forwards and other derivatives as well as repurchase agreements and securities lending agreements. The restrictions prevent a Fund from closing out a qualified financial contract during a specified time period if the counterparty is subject to resolution proceedings and also prohibit a Fund from exercising default rights due to a receivership or similar proceeding of an affiliate of the counterparty. These requirements may increase credit risk and other risks to a Fund.

Cloud-based Computing and Data Storage Risk. Companies involved in, or exposed to, cloud-based computing and data storage-related businesses may have limited product lines, markets, financial resources or personnel. These companies face intense competition and potentially rapid product obsolescence, and many depend on retaining and growing the consumer base of their respective products and services. These companies may not be exclusively or substantially exposed to cloud-based computing and data storage-related businesses (as determined by the Index Provider), but may be exposed, directly or indirectly, to the market and business risks of other companies, industries or sectors, and the Fund may be adversely affected by negative developments impacting those other companies, industries or sectors. These companies may depend on intellectual property rights and may be adversely affected by loss or impairment of those rights. There can be no assurance that companies involved in cloud-based computing and data storage will be able to successfully protect their intellectual property to prevent the misappropriation of their technology, or that competitors will not develop technology that is substantially similar or superior.

Cloud-based computing and data storage companies also depend on a number of third parties to provide services to data centers, which, if interrupted, may impact products and services. These companies are also potential targets for cyberattacks, which may have a materially adverse impact on the performance of these companies. These companies may also be affected by prolonged power outages or shortages, increased costs of energy, or general lack of availability of electrical sources. Cloud-based computing and data storage companies, especially smaller companies, may be more volatile than companies not in the technology sector.

Legal and regulatory changes, particularly related to information privacy and data protection, may impact the products or services of cloud-based computing and data storage companies. Cloud-based computing may face increasing regulatory scrutiny and legal liability, which may limit the development of this technology and impede the growth of companies that develop or use this technology. Similarly, the collection of data from consumers and other sources, and storage of that data, may face increased scrutiny as regulators consider how data may be collected, stored, safeguarded and used. In the event of a data breach or a similar incident, cloud-based computing and data storage companies may face legal liability.

Communications Companies Risk. Communications companies may face rapid product obsolescence as well as unexpected risks and costs related to product compatibility and standardization, new product introduction and technological developments, such as artificial intelligence and machine learning. These companies may need to commit substantial capital to integrate new technologies and develop new products and services. Demographic shifts and changes in consumer preferences and expectations may have negative impacts on their business. Cybersecurity and data privacy risks may be heightened for communications companies, and a theft of proprietary or consumer information or disruptions in service could have a material adverse effect on their operations and reputation. 

Communications companies are subject to extensive government regulation, including licensing and franchise requirements. The costs of complying with regulations and seeking required approvals, as well as potential delays or denials, may adversely affect their business. These companies may face increased government scrutiny and may be subject to adverse government or legal action. They depend significantly on patent and other intellectual property rights, and the loss or impairment of these rights may adversely affect their profitability.

Concentration Risk. A Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities or other assets of one or more issuers, countries or other geographic units, markets, industries, project types, or asset classes. A Fund with investment concentration may be more adversely affected by the underperformance of those assets, may experience greater price volatility and may be more susceptible to adverse economic, market, political or regulatory impacts on those assets compared to a fund that does not concentrate its investments.

Consumer Goods and Services Companies Risk. Many consumer goods and services companies (“consumer companies”) rely heavily on disposable household income and consumer spending and may be impacted by social trends, marketing campaigns, demographic shifts and other factors affecting consumer preferences and demand. In addition, damage to a brand or a reputation crisis can have a substantial adverse impact on consumer companies.

Certain consumer companies, such as those providing discretionary goods or services, may depend more on business cycles, overall economic conditions and consumer confidence. Many consumer goods and services are subject to government regulation and the related compliance costs, and consumer companies also face the risk of product liability claims. Consumer companies also may be adversely affected by volatility in commodity prices, supply chain disruptions and labor shortages.

Currency Risk. Because each Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which a Fund invests depreciates against the U.S. dollar or if there are delays or limits on repatriation of foreign currency, even if the foreign currency value of the Fund’s holdings in that market increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, a Fund’s NAV may change quickly and without warning. In addition, a Fund may incur costs in connection with conversions between U.S. dollars and foreign currencies.

Custody Risk. Custody risk refers to the risks in the process of clearing and settling trades, as well as the holding of securities and other assets by local banks, agents and depositories. These risks are heightened in jurisdictions with less developed markets or less robust settlement and custody infrastructure and processes, and they may result in losses or delays in payments, delivery or recovery of money or other assets. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle. Governments or trade groups may compel local agents to hold securities and other assets in designated depositories that may not be subject

to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities markets are, the higher the degree of custody risk.

Dividend-Paying Stock Risk. Investing in dividend-paying stocks involves the risk that such stocks may fall out of favor with investors and underperform other types of stocks or the broader market. Companies that issue dividend-paying stocks are not required to pay or continue paying dividends on such stocks. It is possible that issuers of dividend-paying stocks will not declare dividends in the future or will reduce or eliminate the payment of dividends (including reducing or eliminating anticipated accelerations or increases in the payment of dividends), which may adversely affect a Fund with such holdings. In addition, the value of dividend-paying stocks can decline when interest rates rise, as fixed-income investments become more attractive to investors.

Electric Vehicles Sector Risk. Companies involved in, or exposed to, electric vehicles-related businesses may have limited product lines, markets, financial resources or personnel. Electric vehicle technology is a relatively new technology and is subject to risks associated with a developing industry. These risks include intense competition, delays or other complications in connection with production, rapid product obsolescence, increased government regulation and market volatility. In addition, certain electric vehicle companies are dependent upon the services of certain key personnel and are susceptible to instability and volatility caused by the actions of or changes to key personnel. The prices of securities of companies involved in a new industry may be more volatile than those in more mature industries.

Many companies involved in, or exposed to, electric vehicles-related businesses depend significantly on retaining and growing the consumer base of their respective products and services. Such companies may not be exclusively or substantially exposed to the electric vehicles sector, but may be substantially exposed to the market and business risks of other industries or sectors, and the Fund may be adversely affected by negative developments impacting those companies, industries or sectors. Electric vehicle companies currently benefit from certain government subsidiaries, policies and economic incentives, which may be reduced or eliminated in the future. In addition, these companies may be adversely affected by loss or impairment of intellectual property rights. There can be no assurance that companies involved in electric vehicle technology will be able to successfully protect their intellectual property to prevent the misappropriation of their technology, or that competitors will not develop technology that is substantially similar or superior to such companies’ technology.

Electric vehicle companies typically engage in significant amounts of spending on research and development, and there is no guarantee that the products or services produced by these companies will be successful. These companies are also susceptible to litigation based on product liability claims and can be significantly affected by insurance costs. In addition, electric vehicle companies may not maintain as much insurance coverage as other types of companies and any insurance coverage may not be sufficient to cover all losses or claims. A loss that is uninsured or that exceeds policy limits may require a company to pay substantial amounts, which could adversely affect the financial condition of the company.

Electric driving vehicle technology companies could be adversely affected by cybersecurity breaches, traffic accidents related to autonomous vehicles, and other issues that could lead to litigation and/or additional regulation. Specifically, electric vehicles may contain complex information technology systems designed with built-in data connectivity to accept and install periodic remote updates, which could be subject to risks associated with the unauthorized access of and control over the vehicles by third parties. Any cyber-attack or data breach of the information technology systems could negatively affect the brand, reputation and financial condition of the company.

Companies involved in the production of batteries for electric vehicles are subject to the effects of price fluctuations of traditional and alternative sources of energy, developments in battery and alternative energy technology and the possibility that government subsidies for, or policies encouraging the use of, alternative energy sources will change or be eliminated. Lithium-ion battery cells, which are used in electric vehicles, have been observed to catch fire or vent smoke and flame, which have raised concerns and may lead to litigation, product recalls or redesign efforts.

Energy Companies Risk. The energy sector tends to be closely tied to the economic cycle and can be significantly affected by supply-demand dynamics and volatility in commodity prices. Energy companies also may be adversely affected by exchange rate fluctuations, war or other conflicts, sanctions, import/export controls, depletion of resources, technological advances and labor relations. This sector generally is subject to substantial government regulation, and companies may incur significant costs in complying with environmental and other laws. Policies that promote energy conservation, clean energy or the transition to low carbon alternatives also may affect the performance of energy companies.

Energy companies may depend on a relatively small number of customers, including governmental entities and utilities. The exploration and production of energy sources and the development of energy infrastructure often require significant capital expenditures, and companies may face high interest costs and difficulty in raising capital. Energy companies also may face challenges from operating in countries with a history of adverse policies or events, such as expropriation, confiscation of assets, corruption, political instability and social unrest. The operations of energy companies may be disrupted by events that target or damage energy infrastructure, including cyber or other attacks, accidents and natural disasters. Energy companies are at risk of liability for environmental harm and other types of damages.

The energy sector may experience significant market volatility. For example, Russia’s large-scale invasion of Ukraine in 2022 led to disruptions and increased volatility in the energy and commodity futures markets due to actual and potential disruptions in the supply and demand for certain commodities, including oil and natural gas. The U.S. and other actors have imposed various sanctions and restrictions on business dealings with Russia, which include restrictions on imports of oil, natural gas and coal. It is impossible to predict the effect of current or future sanctions and restrictions, the extent and duration of the conflict, and associated disruptions in the energy sector. The effect of these events or any related developments could be significant and may have a severe adverse effect on a Fund’s performance.

Energy Storage Solutions Sector Risk. The market value of securities in the energy storage solutions sector may decline for the following reasons, among others: changes in and volatility of traditional and alternative energy prices, energy supply and demand, government regulation and intervention, trade treaties, exchange rates, interest rates, tax treatment, energy conservation efforts, availability of certain inputs and materials required for production, depletion of resources, technological developments, labor relations, costs related to exploration, mining, and production, and general economic conditions. Risks associated with hazardous materials, liability from accidents resulting in injury or loss of life or property, pollution or other environmental problems, equipment malfunctions or mishandling of materials and terrorism, cyber incidents, political strife or natural disasters may also significantly affect this sector.

Companies in the energy storage solutions sector, including, but not limited to, battery, fuel cell, and hydrogen companies, may depend largely on the availability of hydrogen gas, certain third-party key suppliers for components in their products, and a small number of customers for a significant portion of their business. Because lithium, hydrogen, copper, aluminum, steel and other raw materials are often critical components of the products manufactured by these companies, fluctuations in prices, and in commodities prices, as applicable, for such raw materials may impact their profitability.

Companies in the energy storage solutions sector may also operate in, or engage in transactions involving, countries that have less developed regulatory regimes or a history of expropriation, confiscation of assets, foreign investment restrictions, nationalization or other adverse policies or that are at greater risk of political and social unrest, coups or labor disruptions. The energy storage solutions sector may also be significantly affected by changes in governmental regulations and policies, such as subsidies and tax incentives, including the possibility that government subsidies and/or tax incentives for alternative energy will be eliminated.

Equity Securities Risk. Equity securities are subject to changes in value due to general market or economic conditions, perceptions about the markets in which issuers participate or a number of factors relating to a specific issuer. Investments in equity securities may be more volatile than investments in other asset classes. Equity securities (both common and preferred stock) are subordinated to debt securities in a company’s capital structure, and so equity holders are generally subject to more risks, particularly in the event of an issuer’s bankruptcy. Common stock has the lowest priority and the greatest risks, including with respect to dividends and any liquidation payments.

ESG Risk. To the extent that a Fund’s Underlying Index uses criteria related to the ESG characteristics of issuers, this may limit the types and number of investment opportunities available to the Fund and, as a result, the Fund may underperform other funds whose underlying index does not use ESG criteria. An Underlying Index’s use of ESG criteria may result in a Fund investing in, or allocating greater weight to, securities or market sectors that underperform the market as a whole or underperform other funds that use ESG criteria. In addition, the use of representative sampling may result in the divergence of a Fund's overall ESG characteristics or ESG risk from those of the Underlying Index.

An Index Provider evaluates securities for inclusion and/or weighting in such an Underlying Index based on ESG criteria and data provided by the Index Provider or third parties. The Index Provider’s evaluation of securities’ ESG characteristics depends on these criteria and data, which may vary by index provider, and no assurance can be given that they will be complete, accurate or current. In addition, an Index Provider may evaluate security-level ESG data (including ratings) and, if applicable, ESG objectives or constraints that are relevant to an Underlying Index only at index reviews or rebalances. Securities included in an Underlying Index may cease to meet the relevant ESG criteria but may nevertheless remain in the Underlying Index and in the Fund using the Underlying Index until the next review or rebalance by the Index Provider. As a result, certain securities in the Underlying Index, or the Underlying Index as a whole, may not meet the relevant ESG objectives or constraints at all times. If the ESG assessment of a security in an Underlying Index or a Fund changes, neither the Fund nor BFA accepts any liability in relation to such change. BFA does not monitor securities in an Underlying Index with respect to ESG objectives or constraints applied by the Index Provider and is not responsible for changes to the ESG assessment of a security in an Underlying Index between rebalances. In addition, BFA does not assess the validity of an Index Provider’s evaluation of the ESG characteristics of securities or the criteria and data used in such evaluation.

The impacts of risks related to ESG investing are likely to change over time, and new ESG risks may be identified as further data and information regarding ESG factors and impacts become available. In addition, methodologies for ESG investing continue to develop, and the ESG methodology applied by an Index Provider may change over time.

European Economic Risk. The Economic and Monetary Union (the “eurozone”) of the European Union (the “EU”) requires compliance by member states that are members of the eurozone with restrictions on inflation rates, deficits, interest rates and debt levels, as well as fiscal and monetary controls, each of which may significantly affect every country in Europe, including those countries that are not members of the eurozone. Additionally, European countries outside of the eurozone may present economic risks that are independent of the indirect effects that eurozone policies have on them. In particular, the United Kingdom's (the “U.K.”) economy may be affected by global economic, industrial and financial shifts. Changes in imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro (the common currency of eurozone countries), the default or threat of default by an EU member state on its sovereign debt and/or an economic recession in an EU member state may have a significant adverse effect on the economies of other EU member states and their trading partners. The European financial markets have historically experienced volatility and adverse trends due to concerns about economic downturns or government debt levels in several European countries, including, but not limited to, Austria, Belgium, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. These events have affected and may in the future adversely affect the exchange rate of the euro and may significantly affect European countries.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. The U.K. left the EU (“Brexit”) on January 31, 2020. Brexit could adversely affect European or worldwide political, regulatory, economic or market conditions and could contribute to instability in global political institutions, regulatory agencies and financial markets.

The national politics of countries in Europe have been unpredictable and subject to influence by disruptive political groups and ideologies, including, for example, secessionist movements. The governments of European countries may be subject to change and such countries may experience social and political unrest. Unanticipated or sudden political or social developments may result in sudden and significant investment losses. The occurrence of terrorist incidents throughout Europe or war in the region could also impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of a Fund's investments.

Russian Invasion of Ukraine. Russia launched a large-scale invasion of Ukraine on February 24, 2022. The extent and duration of the military action, resulting sanctions and resulting future market disruptions, including declines in its stock markets and the value of the ruble against the U.S. dollar, are impossible to predict, but could be significant. Disruptions caused by Russian military action or other actions (including cyberattacks and espionage) or resulting actual and threatened responses to such activity, including purchasing and financing restrictions, boycotts or changes in consumer or purchaser preferences, sanctions, import and export restrictions, tariffs or cyberattacks on the Russian government, Russian companies or Russian individuals, including politicians, may impact Russia's economy, Russian issuers of securities in which a Fund invests, or the economies of Europe as a whole. Actual and threatened responses to Russian military action may also impact the markets for certain Russian commodities, such as oil and natural gas, as well as other sectors of the Russian economy, and are likely to have collateral impacts on such sectors across Europe and globally.

Exponential Technologies Risk. Technologies perceived to displace older technologies or create new markets may not in fact do so. Companies that initially develop a novel technology may not be able to capitalize on the technology. Companies that develop exponential technologies may face political or legal attacks from competitors, industry groups or local and national governments. These companies may also be exposed to risks applicable to sectors other than the exponential technology theme for which they are chosen, and the securities issued by these companies may underperform the securities of other companies that are primarily focused on a particular theme. The Fund may invest in a company that does not currently derive any revenue from exponential technologies, and there is no assurance that a company will derive any revenue from exponential technologies in the future. An exponential technology may constitute a small portion of a company’s overall business. As a result, the success of an exponential technology may not affect the value of the equity securities issued by the company.

Financial Companies Risk. Financial services companies are subject to extensive governmental regulation and intervention, which may change frequently and may adversely affect their profitability, the scope of their activities, the prices they can charge, the amount of capital and liquid assets they must maintain and their size, among other things. Financial services companies also may be significantly affected by, among other things, interest rates, economic conditions, credit rating downgrades, adverse public perception and exposure concentration. Increased risk-taking by financial companies may result in greater overall risk in the global financial sector. Certain events may cause an unusually high degree of volatility in financial markets and pose the risk of large losses for financial services companies.

Financial companies frequently operate with substantial financial leverage and are exposed directly to the credit risk of their borrowers and counterparties, which also may be leveraged to an unknown degree. Financial companies may have significant exposure to the same borrowers and counterparties; as a result, a borrower’s or counterparty’s inability to meet its obligations to one company may affect other financial companies with exposure to the same borrower or counterparty. This interconnectedness of risk may result in significant negative impacts to companies with direct exposure to the defaulting counterparty as well as adverse cascading effects in the markets and the financial sector generally.

FinTech Risk. Companies developing financial technologies or using technology-enabled innovation in the financial services industry (“FinTech Companies”) could result in new business models, applications, processes or products with an associated effect on the provision of financial services. FinTech Companies may seek to disrupt or displace established financial institutions and may face competition from larger and more established companies. FinTech Companies may not be able to capitalize on their disruptive technologies when facing political and/or legal attacks from competitors, industry groups or local and national governments. These companies may depend on intellectual property rights and may be adversely affected by loss or impairment of those rights. Many Fintech Companies are not currently profitable, and there can be no assurance that these companies will be profitable in the future. Additionally, FinTech Companies may be adversely impacted by potential rapid product obsolescence, cybersecurity attacks and disruptions in the technology they depend on.

Legal and regulatory changes, particularly related to information privacy and data protection, may impact the products or services of FinTech Companies. Laws and regulations typically vary by state and by country, which may create challenges for FinTech Companies to achieve scale. Increasing regulatory scrutiny and legal liability may limit the development and impede the growth of these companies. Similarly, the collection and storage of data from consumers and other sources may face increased scrutiny as regulators consider how data may be collected, stored, safeguarded and used. Further, in the event of a data breach or a similar incident, FinTech Companies may face legal liability.

Geographic and Security Risks. Issuers in a Fund’s portfolio may be located in, or otherwise connected to, parts of the world affected by natural disasters, such as severe heat, earthquakes, tornadoes, volcanic eruptions, wildfires, droughts, floods, hurricanes and tsunamis. In addition, issuers may be impacted by security concerns with respect to a country or region, such as war and other types of conflict, terrorism, strained international relations and territorial disputes. Any of these events may adversely affect the issuers, markets and economies to which a Fund is exposed, which may adversely affect the value of the Fund.

Healthcare Companies Risk. The profitability of healthcare companies may be adversely affected by the following factors, among others: extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, a limited number of products, labor shortages, supply chain issues and industry innovation. Many new products in the healthcare sector entail significant research and development and require regulatory approval, all of which may be long and costly, and such efforts ultimately may be unsuccessful. Many healthcare companies depend heavily on obtaining and defending patents, which can be costly, and may be adversely affected by the expiration of patents. Healthcare companies also are subject to extensive litigation based on product liability and similar claims.

Illiquid Investments Risk. An illiquid investment is any investment that a Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without significantly changing the market value of the investment. An investment may be illiquid due to, among other things, fewer participants or less capacity to make a market in the investment, the lack of an active market for the investment, capital controls, delays or limits on repatriation of local currency, and the insolvency of local governments. To the extent that a Fund invests in securities or other assets with substantial market and/or credit risk, the Fund will tend to have increased exposure to the risks associated with illiquid investments. Illiquid investments may be harder to value, especially in changing markets.

Liquid investments may become illiquid after purchase by a Fund, particularly during periods of market turmoil. There can be no assurance that a security or other asset that is deemed to be liquid when purchased will continue to be liquid for as long as it is held by a Fund, and any security or other asset held by a Fund may be deemed an illiquid investment pursuant to the Fund’s liquidity risk management program.

Holdings of illiquid investments may reduce a Fund’s returns because the Fund may be unable to transact at advantageous times or prices. If a Fund is forced to sell underlying investments at reduced prices or under unfavorable conditions to meet redemption requests or for other cash needs, the Fund may suffer a loss. This may be magnified in a rising interest rate environment or other circumstances where redemptions of Fund shares may be greater than normal. If other market participants attempt to liquidate holdings at the same time as a Fund, this will lead to an increased supply of the Fund’s underlying investments in the market and contribute to greater illiquid investments risk and downward pricing pressure. In addition, if a Fund is limited in its ability to sell illiquid investments during periods when shareholders are redeeming their shares, the Fund will need to sell liquid securities to meet redemption requests, and illiquid securities will become a larger portion of the Fund’s holdings. During periods of market volatility, liquidity in the market for a Fund’s shares may be impacted by the liquidity in the market for the underlying securities or other assets held by the Fund, which could lead to the Fund’s shares trading at a premium or discount to the Fund's NAV.

Index-Related Risk. A Fund that tracks an Underlying Index seeks to achieve a return that corresponds generally to the price and yield performance, before fees and expenses, of its Underlying Index as published by the Index Provider. There is no assurance that the Index Provider or its agents will construct or calculate the Underlying Index accurately. While the Index Provider describes what the Underlying Index is designed to achieve, neither the Index Provider nor its agents provide any warranty or accept any liability regarding the quality, accuracy or completeness of the Underlying Index or its related data, and they do not guarantee that the Underlying Index will be in line with the Index Provider’s methodology. BFA also does not provide any warranty or guarantee against the Index Provider’s or any agent’s errors.

The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither a Fund nor BFA can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Fund meeting its investment objective. Errors in index data, index computations or the construction of an Underlying Index in accordance with its methodology may occur, and the Index Provider may not identify or correct them promptly or at all, particularly for indexes that are less commonly used as benchmarks. In addition, there may be heightened risks associated with the adequacy and reliability of information about emerging markets constituents, as such markets may have less information available or less regulatory oversight. Errors related to an Underlying Index may negatively or positively impact a Fund and its shareholders. For example, if the Underlying Index contains incorrect constituents, the Fund will have exposure to such constituents and will be underexposed to the Underlying Index’s other constituents. Shareholders should understand that any gains from an Index Provider’s errors will be kept by the Fund and its shareholders and any losses or costs from such errors will be borne by the Fund and its shareholders.

Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact an Index Provider or a third-party data provider and could cause the Index Provider to postpone a scheduled rebalance to an Underlying Index. This could cause the Underlying Index to vary from its normal or expected composition. If a scheduled rebalance is postponed, index constituents that would otherwise be removed at the rebalance (due to, for example, changes in market capitalization or issuer credit ratings) may remain, causing the performance and constituents of the Underlying Index to vary from those expected under normal conditions. In addition, to the extent circumstances evolve between periodic index reviews and reconstitutions, an Underlying Index may include constituents that do not align with its objective or selection criteria, and the Fund tracking the Underlying Index may be similarly affected.

In addition to scheduled rebalances, an Index Provider or its agents may carry out ad hoc index rebalances due to reaching certain weighting constraints, unusual market conditions, corporate events, or corrections of errors. The relevant Fund will in turn rebalance its portfolio to attempt to increase the correlation between the portfolio and the Underlying Index. The Fund and its shareholders will directly bear any transaction costs and market exposure from such portfolio rebalancing. Therefore, index-related errors and ad hoc rebalances may increase a Fund’s costs and tracking error.

Industrial Companies Risk. Industrial companies face a number of risks, including supply chain and distribution disruptions, business interruptions, third-party vendor risks, cyber attacks, trade disputes, product recalls, liability and environmental damage claims, scarcity of materials or parts, excess capacity, changes in consumer preferences, and volatility in commodity prices and currencies. The products of industrial companies may face obsolescence due to technological developments and new product introduction. Furthermore, changes in trade restrictions and tariffs as well as broader geopolitical developments could adversely affect industrial companies. These companies also may be significantly affected by domestic and international economic conditions, legislative and regulatory changes, and labor relations. Industrial companies may depend on public or private sector financing, which may become difficult to obtain due to government spending constraints or reduced availability of capital. Such companies may be unable to protect their intellectual property rights or may be liable for infringing the intellectual property rights of others.

Issuer Risk. The performance of a Fund depends on the performance of individual securities or other assets to which the Fund has exposure. The value of securities or other assets may decline, or perform differently from the market as a whole, due to changes in the financial condition or credit rating of the issuer or counterparty.

Large Shareholder and Large-Scale Redemption Risk. Certain shareholders of a Fund, including an Authorized Participant, a third-party investor, the Fund’s adviser, an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own or manage a substantial amount of Fund shares or may hold their investment in the Fund for a limited period of time. These shareholders may also pledge or loan Fund shares (to secure financing or otherwise), which may result in the shares becoming concentrated in another party. There can be no assurance that any large shareholder or large group of shareholders would not redeem their investment or that the size of a Fund would be maintained. Redemptions of a large number of Fund shares may adversely affect a Fund’s liquidity and net assets. To the extent a Fund permits redemptions in cash, these redemptions may force the Fund to sell portfolio securities or other assets when it might not otherwise do so, which may negatively impact the Fund’s NAV, have a material effect on the market price of Fund shares, increase the Fund’s brokerage costs, accelerate the realization of taxable income and/or capital gains, and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such tax year. A Fund also may be required to sell its more liquid investments to meet a large redemption, in which case the Fund’s remaining assets may be less liquid, more volatile, and more difficult to price.

To the extent these large shareholders transact in Fund shares on the secondary market, such transactions may account for a large percentage of the trading volume for Fund shares and may, therefore, have a material upward or downward effect on the market price of the shares. In addition, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would, diluting its investment returns.

Management Risk. An index Fund invests in securities or other assets included in, or representative of, its Underlying Index, regardless of their investment merits. Such a Fund may be affected by a general decline in market segments related to its Underlying Index, and BFA generally does not attempt to invest the Fund’s assets in defensive positions under any market conditions, including declining markets. Market disruptions and regulatory restrictions could have an adverse effect on a Fund’s ability to adjust its exposure to the required levels in order to track its Underlying Index. Because BFA uses a representative sampling indexing strategy, a Fund will not fully replicate its Underlying Index and may hold securities or other assets not included in the Underlying Index. As a result, a Fund is subject to the risk that BFA’s investment strategy, whose implementation is subject to a number of constraints, may not produce the intended results. There is no guarantee that a Fund’s investment results will have a high degree of correlation to those of its Underlying Index or that a Fund will achieve its investment objective.

Market Risk. A Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. The value of a financial instrument or other asset may decline due to changes in general market conditions, economic trends or events that are not specifically related to the particular instrument or asset, or factors that affect one or more issuers, counterparties, exchanges, countries or other geographic units, markets, industries, or asset classes. Local, regional or global events such as war, acts of terrorism, pandemics or other public health issues, recessions, the prospect or occurrence of a sovereign default or other financial crisis, or other events could have a significant impact on a Fund and its investments and could result in increased premiums or discounts to a Fund’s NAV. Changes in market and economic conditions generally do not have the same impact on all types of instruments and assets.

Market Trading Risk. A Fund faces numerous market trading risks, any of which may lead to its shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to the NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.

Absence of an Active Primary Market. Although Fund shares are listed for trading on one or more stock exchanges, there can be no assurance that an active primary trading market for Fund shares will develop or be maintained by market makers or Authorized Participants.

Secondary Listing Risks. A Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. Fund shares also may be available to non-U.S. investors through funds or structured investment vehicles similar to depositary receipts. There can be no assurance that a Fund’s shares will continue to trade on any such stock exchange or in any market or that a Fund’s shares will continue to meet the requirements for exchange listing or market trading. A Fund’s shares may be less actively traded in certain markets than in others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information that is available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of a Fund may trade in the secondary market at times when the Fund does not accept orders to create or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts to NAV than might be experienced at times when the Fund accepts creation and redemption orders. Securities held by a Fund may be traded in markets that close at a different time than an exchange on which Fund shares are traded. Liquidity in those securities may be reduced after the applicable closing time. As a result, during the time when the exchange is open but after the applicable market closing, fixing or settlement time, there may be wider bid/ask spreads on the exchange and a greater premium or discount to NAV.

In stressed market conditions, the market for a Fund’s shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, and an investor may be unable to sell their Fund shares.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or for other reasons. In times of extraordinary market volatility, Fund shares may be subject to trading halts pursuant to “circuit breaker” rules of a stock exchange or market. If there is a trading halt or unanticipated closure of an exchange or market, an investor may be unable to purchase or sell Fund shares. In addition, if trading in certain securities or financial instruments is restricted, this may disrupt a Fund’s creation/redemption process, affect the price at which Fund shares trade in the secondary market, and result in a Fund being unable to trade certain securities or financial instruments. In such circumstances, a Fund may be unable to rebalance its portfolio or accurately price its portfolio holdings and may incur substantial trading losses.

Shares of a Fund, similar to shares of other issuers listed on a stock exchange, may be sold short and are therefore subject to the risk of increased volatility and price decreases associated with being sold short. In addition, trading activity in derivative products based on a Fund may lead to increased trading volume and volatility in the secondary market for the shares of the Fund.

Fund Shares May Trade at Prices Other Than NAV. Shares of a Fund trade on stock exchanges at prices at, above or below the Fund’s most recent NAV. A Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s portfolio holdings. The trading price of a Fund’s shares fluctuates throughout trading hours based on both market supply of and demand for Fund shares and the underlying value of the Fund’s portfolio holdings or NAV. As a result, the trading prices of a Fund’s shares may deviate significantly from NAV during times of market volatility, significant redemption requests, or other unusual market conditions

However, because Fund shares can be created and redeemed in Creation Units at NAV, BFA believes that large discounts or premiums to a Fund’s NAV are not likely to be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs). While the creation/redemption feature is designed to make it more likely that a Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for shares of a Fund that differ significantly from its NAV. Authorized Participants may be less willing to create or redeem a Fund’s shares if there is a lack of an active market for such shares or the Fund’s underlying investments, which may contribute to the Fund’s shares trading at a premium or discount to NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling Fund shares through a broker, you will likely incur a brokerage commission and other charges. In addition, you may incur the cost of the “spread,” which is the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). The spread varies over time for Fund shares based on trading volume and market liquidity. It is generally narrower if a Fund has more trading volume and market liquidity and wider if a Fund has less trading volume and market liquidity. Increased market volatility also may cause wider spreads. In addition, there may be regulatory and other charges that are incurred as a result of trading activity. Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results, and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.

Materials Companies Risk. The materials sector tends to be closely tied to the economic cycle and can be significantly affected by supply-demand dynamics. Materials companies may be adversely affected by commodity price volatility, exchange rate fluctuations, social and political unrest, war, import and export controls, supply chain disruption, increased competition, depletion of resources, technical advances, labor relations, litigation and government regulations, among other factors. Materials companies are at risk of liability for environmental damage and product liability claims and may incur significant costs in complying with environmental laws.

Mid-Capitalization Companies Risk. Investments in mid-capitalization companies may be riskier, less liquid, more volatile and more susceptible to economic, market and industry changes than investments in large-capitalization companies. Mid-capitalization companies may have more limited product lines, markets, financial resources and management experience. As a result, they generally are more vulnerable than large-capitalization companies to adverse business and economic developments. Mid-capitalization companies may have a shorter business track record, with relatively less information available to investors. The securities of mid-sized companies may trade less frequently and in smaller volumes than the securities of larger companies.

Middle Eastern Economic Risk. Many Middle Eastern countries have little or no democratic tradition, and the political and legal systems in such countries may adversely impact the companies in which the Fund invests and, as a result, the value of the Fund. Middle Eastern governments have exercised and continue to exercise substantial influence over many aspects of the private sector. Many economies in the Middle East are highly reliant on income from the sale of oil and natural gas or trade with countries involved in the sale of oil and natural gas, and their economies are therefore vulnerable to changes in the market for oil and natural gas and foreign currency values. As global demand for oil and natural gas fluctuates, many Middle Eastern economies may be significantly impacted. A sustained decrease in commodity prices could have a significant negative impact on all aspects of the economy in the region. Middle Eastern economies may be subject to acts of terrorism, political strife, religious, ethnic or socioeconomic unrest and sudden outbreaks of hostilities with neighboring countries.

Certain Middle Eastern countries have strained relations with other Middle Eastern countries due to territorial disputes, historical animosities, international alliances, religious tensions or defense concerns, which may adversely affect the economies of these countries. Certain Middle Eastern countries experience significant unemployment, as well as widespread underemployment.

Many Middle Eastern countries periodically have experienced political, economic and social unrest as protestors have called for widespread reform. Some of these protests have resulted in a governmental regime change, internal conflict or civil war. If further regime changes were to occur, internal conflict were to intensify, or a civil war were to continue in any of these countries, such instability could adversely affect the economies of Middle Eastern countries in which the Fund invests and could decrease the value of the Fund’s investments.

National Closed Market Trading Risk. To the extent that securities or other assets held by a Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between such asset’s current price and its last quoted price (i.e., the quote from the closed foreign market to the Fund). The impact of a closed foreign market on a Fund is likely to be greater where a large portion of the Fund’s holdings trade on a closed foreign market or when a foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to a Fund’s NAV that may be greater than those experienced by other funds.

Neuroscience Companies Risk. Neuroscience companies are often subject to the potential or actual performance of a limited number of products or technologies and, accordingly, may be greatly affected if any of their products or technologies proves to be, among other things, unsafe, ineffective or unprofitable, or if such product or technology is not approved by regulators or other governing bodies. The research and development and other costs associated with developing or procuring new drugs, products or technologies and the related intellectual property rights can be significant. The results of such research and expenditures are unpredictable and may not lead to commercially successful products. The development and protection of intellectual property rights are critical for neuroscience companies, whose product pipeline and profitability may be affected significantly by the expiration of patents or the loss of, or the inability to enforce, intellectual property rights. Neuroscience companies are also subject to the risk of product liability claims, which may affect the value of their equity securities. Such companies may have thin capitalization and limited markets, financial resources or personnel, and they are also susceptible to the market and business risks of related industries, such as biotechnology, pharmaceuticals and health care equipment.

Neuroscience companies may face political, legal or regulatory challenges or constraints from competitors, industry groups or local and national governments. Governmental regulation may delay or inhibit the release of new products. The process for obtaining regulatory approval from governmental authorities, such as the U.S. Food and Drug Administration, can be long and costly, and there can be no assurance that the necessary approvals will be obtained or maintained. Neuroscience companies may also be subject to expenses and losses from expensive insurance costs due to the risks of product liability claims and extensive litigation based on intellectual property. Health care providers, principally hospitals, that transact with neuroscience companies often rely on third-party payors, such as Medicare, Medicaid and other government-sponsored programs, private health insurance plans and health maintenance organizations, to reimburse all or a portion of the cost of neuroscience-related products or services. As a result, neuroscience companies may be sensitive to legislative changes and reductions in government spending for such programs, as well as state or local health care reform measures. The stock prices of companies in the neuroscience industry have been and will likely continue to be extremely volatile, particularly when their products are up for regulatory approval or under regulatory scrutiny.

Non-Diversification Risk. A Fund that is classified as “non-diversified” may invest a greater percentage of its assets in securities or other instruments representing a small number of issuers or counterparties, compared with funds that are classified as “diversified.” A non-diversified Fund thus may be more susceptible to the risks associated with these particular issuers or counterparties. The gains and losses

on such holdings may have a greater impact on a non-diversified Fund’s performance than they would on the performance of a diversified Fund, and a non-diversified Fund’s NAV may be more volatile.

Non-U.S. Securities Risk. Securities issued by non-U.S. issuers (including depositary receipts) are subject to different legal, regulatory, political, economic, and market risks than securities issued by U.S. issuers. To the extent that investments are made in a limited number of countries, events in those countries will have a more significant impact on a Fund. The risks of investing in non-U.S. securities include the following, any of which may have an adverse impact on a Fund:

■

Less liquid markets, which may make valuing securities more difficult;

■

Greater market volatility;

■

Government intervention in issuers' operations or structure;

■

Government expropriation or nationalization of assets;

■

Exchange rate fluctuations and currency controls;

■

Limitations on the foreign ownership of securities;

■

Imposition of withholding or other taxes;

■

Restrictions on the repatriation of capital;

■

Higher transaction and custody costs;

■

Foreign market trading hours, different clearing and settlement procedures, and holiday schedules, which may limit a Fund's ability to engage in portfolio transactions;

■

Less regulation of the securities and other financial markets;

■

Less availability of public information about issuers;

■

Weaker accounting, audit, disclosure and financial reporting requirements and the risk of being delisted from U.S. exchanges;

■

Difficulties in enforcing contractual obligations; and

■

Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities, and shareholder rights that are less robust than those that apply in the U.S.

Withholding Tax Reclaims Risk. A Fund that holds non-U.S. securities may file claims to recover withholding tax on dividend and interest income (if any) received from issuers in certain countries where such withholding tax reclaim is possible. Whether or when a Fund will receive a withholding tax refund is within the control of the tax authorities in such countries. Where a Fund expects to recover withholding tax based on a continuous assessment of the probability of recovery, the Fund’s NAV generally includes accruals for such tax refunds. The Fund continues to evaluate tax developments for potential impact to the probability of recovery. If the likelihood of receiving a tax refund materially decreases, such as due to a change in tax regulation or approach, accruals in a Fund’s NAV for such refunds may be written down partially or in full, which will adversely affect the Fund’s NAV. Investors in a Fund at the time when an accrual is written down will bear the impact of any resulting reduction in NAV regardless of whether they were investors during the accrual period. Conversely, if a Fund receives a tax refund that was not previously accrued, investors in the Fund at the time the claim is successful will benefit from any resulting increase in the Fund’s NAV. Investors who sold their shares prior to such time will not benefit from any such NAV increase.

North American Economic Risk. A decrease in imports or exports, changes in trade regulations or an economic recession in any North American country can have a significant economic effect on the entire North American region and on some or all of the North American countries in which a Fund invests.

The U.S. is Canada's and Mexico's largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the U.S. and Mexico, total merchandise trade among the three countries has increased. However, political developments including the implementation of tariffs by the U.S. and the renegotiation of NAFTA in the form of the United States-Mexico-Canada Agreement (“USMCA”), which replaced NAFTA on July 1, 2020, could negatively affect North America’s economic outlook and, as a result, the value of securities held by a Fund. Policy and legislative changes in one country may have a significant effect on North American markets generally, as well as on the value of certain securities held by a Fund.

Operational and Technology Risks. A Fund and the entities with which it interacts directly or indirectly are susceptible to operational and technology risks, including those related to human errors, processing errors, communication errors, systems failures, cybersecurity incidents, and the use of artificial intelligence and machine learning (“AI”), which may result in losses for the Fund and its shareholders or impair the Fund’s operations. These entities include, but are not limited to, a Fund’s adviser, administrator, distributor, other service providers (e.g., index and benchmark providers, accountants, custodians, and transfer agents), financial intermediaries, counterparties, market makers, Authorized Participants, listing exchanges, other financial market operators, and governmental authorities. Operational and technology risks for the issuers in which a Fund invests could also result in material adverse consequences for such issuers and may cause the Fund’s investments in such issuers to lose value. A Fund may incur substantial costs in order to mitigate operational and technology risks.

Cybersecurity incidents can result from deliberate attacks or unintentional events against an issuer in which a Fund invests, the Fund or any of its service providers. They include, but are not limited to, gaining unauthorized access to systems, misappropriating assets or sensitive

information, corrupting or destroying data, and causing operational disruption. Geopolitical tension may increase the scale and sophistication of deliberate attacks, particularly those from nation states or from entities with nation state backing. Cybersecurity incidents may result in any of the following: financial losses; interference with a Fund’s ability to calculate its NAV; disclosure of confidential information; impediments to trading; submission of erroneous trades by a Fund or erroneous subscription or redemption orders; the inability of a Fund or its service providers to transact business; violations of applicable privacy and other laws; regulatory fines; penalties; reputational damage; reimbursement or other compensation costs; and other legal and compliance expenses. Furthermore, cybersecurity incidents may render records of a Fund, including records relating to its assets and transactions, shareholder ownership of Fund shares, and other data integral to a Fund’s functioning, inaccessible, inaccurate or incomplete. Power outages, natural disasters, equipment malfunctions and processing errors that threaten information and technology systems relied upon by a Fund or its service providers, as well as market events that occur at a pace that overloads these systems, may also disrupt business operations or impact critical data. In addition, the risks of increased use of AI technologies, such as machine learning, include data risk, transparency risk, and operational risk. The AI technologies, which are generally highly reliant on the collection and analysis of large amounts of data, may incorporate biased or inaccurate data, and it is not possible or practicable to incorporate all relevant data into such technologies. The output or results of any such AI technologies may therefore be incomplete, erroneous, distorted or misleading. Further, AI tools may lack transparency as to how data is utilized and how outputs are generated. AI technologies may also allow the unintended introduction of vulnerabilities into infrastructures and applications. A Fund and its shareholders could be negatively impacted as a result of these risks associated with AI technologies. AI technologies and their current and potential future applications, and the regulatory frameworks within which they operate, continue to quickly evolve, and it is impossible to anticipate the full scope of future AI capabilities or rules and the associated risks to a Fund.

While a Fund’s service providers are required to have appropriate operational, information security and cybersecurity risk management policies and procedures, their methods of risk management may differ from those of the Fund in the setting of priorities, the personnel and resources available or the effectiveness of relevant controls. Each Fund and its adviser seek to reduce these risks through controls, procedures and oversight, including establishing business continuity plans and risk management systems. However, there are inherent limitations in such plans and systems, including the possibility that certain risks that may affect a Fund have not been identified or may emerge in the future; that such plans and systems may not completely eliminate the occurrence or mitigate the effects of operational or information security disruptions or failures or of cybersecurity incidents; or that prevention and remediation efforts will not be successful or that incidents will go undetected. A Fund cannot control the systems, information security or other cybersecurity of the issuers in which it invests or its service providers, counterparties, and other third parties whose activities affect the Fund.

Lastly, the regulatory climate governing cybersecurity and data protection is developing quickly and may vary considerably across jurisdictions. Regulators continue to develop new rules and standards related to cybersecurity and data protection. Compliance with evolving regulations can be demanding and costly, requiring substantial resources to monitor and implement required changes.

Reliance on Trading Partners Risk. The economies of some countries or regions depend on trading with certain key trading partners. A reduction in spending on the products and services of these countries or regions, the institution of tariffs or other trade barriers by a key trading partner or a slowdown in the economy of a key trading partner may cause an adverse impact on the economies of such countries or regions and may negatively impact the performance of a Fund with exposure to those countries or regions.

Risk of Investing in China. Investments in Chinese securities, including certain Hong Kong-listed and U.S.-listed securities, subject a Fund to risks specific to China. China is subject to a considerable degree of economic, political and social instability.

Political and Social Risk. The Chinese government is authoritarian and has periodically used force to suppress civil dissent. Disparities of wealth and the pace of economic liberalization may lead to social turmoil, violence and labor unrest. In addition, China continues to experience disagreements related to integration with Hong Kong and religious and nationalist disputes in Tibet and Xinjiang. There is also a greater risk in China than in many other countries of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation as a result of internal social unrest or conflicts with other countries. Unanticipated political or social developments may result in sudden and significant investment losses. China’s income inequality, rapidly aging population and significant environmental issues also are factors that may affect the Chinese economy.

Government Control and Regulations. Despite the Chinese government’s implementation of economic and market reforms in recent decades, government control over certain sectors and enterprises and significant regulation of investment and industry are still pervasive. China has restrictions on investment in companies or industries deemed to be sensitive to particular national interests, trading of securities of Chinese issuers, foreign ownership of Chinese corporations and/or the repatriation of assets by foreign investors. Restrictions on foreign ownership of Chinese securities may have adverse effects on a Fund’s liquidity and performance and could lead to higher tracking error. Chinese government intervention in the market may have a negative impact on market sentiment, which may in turn affect the performance of the Chinese economy and a Fund’s investments. Chinese markets generally continue to experience inefficiency, lack of publicly available information, and political and social instability and may be subject to volatility and pricing anomalies resulting from governmental influence. Chinese companies, such as those in the financial services, technology and potentially other sectors, are also subject to the risk that Chinese authorities can intervene in their operations and structure, which may negatively affect the value of a Fund’s investments.

Economic Risk. The Chinese economy is highly reliant on trade and may be adversely affected by, among other things, a deterioration in global demand and spending for Chinese exports or a contraction in spending on domestic goods by Chinese consumers. The institution of additional tariffs or other trade barriers (including as a result of heightened trade tensions between China and the U.S. or in response to actual or alleged Chinese cyber activity) or a downturn in any of the economies of China’s key trading partners may have an adverse impact

on the Chinese economy and companies in which a Fund invests. The current political climate has intensified concerns about a potential trade war between China and the U.S. as each country has imposed tariffs on the other. These actions and their consequences (which are difficult to predict) could have a negative impact on a Fund’s performance. It is unclear whether further tariffs or other escalating actions may occur.

In addition, certain Chinese companies (which may change from time to time) are directly or indirectly subject to economic or trade restrictions imposed by the U.S. or other governments due to national security, human rights or other concerns of such government. For example, certain foreign technology companies are subject to export controls as those companies are believed to pose a risk to U.S. interests. The U.S. also bans imports of goods produced in certain regions of China or by certain Chinese companies due to concerns about forced labor. Such restrictions may have unanticipated and adverse effects on the Chinese economy and companies. Any action that targets Chinese financial markets or securities exchanges could interfere with orderly trading, delay settlement or cause market disruptions. A Fund’s Underlying Index may include companies that are subject to economic or trade restrictions (but not investment restrictions) imposed by the U.S. or other governments. So long as these restrictions do not include restrictions on investments, a Fund is generally expected to invest in such companies, consistent with its objective to track the performance of its Underlying Index. Other economic challenges for China include indebtedness, weak consumer demand, and an aging population. China continues to face pressure from its trading partners over its exporting of its excess industrial capacity and overall approach to economic management.

Expropriation Risk. The Chinese government maintains a major role in economic policymaking, and investing in China involves risk of loss due to expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested.

Security Risk. China has strained international relations with Taiwan, Japan, the Philippines, India, and other neighbors due to territorial disputes, historical animosities, defense concerns and other security concerns. China has a complex territorial dispute regarding the sovereignty of Taiwan and has pledged to take control of Taiwan, including by force if necessary. The Chinese military has conducted military drills around Taiwan in connection with China’s claim to Taiwan. Taiwan-based companies and individuals are significant investors in China. Continuing hostility between China and Taiwan may have an adverse impact on their economies and markets and on the value of a Fund’s investments in China, Taiwan or the region, may cause a suspension in a Fund’s ability to trade in certain securities or other assets, or may otherwise make such investments impracticable or impossible. Frictions between China and the Philippines in the South China Sea pose a risk of escalation potentially leading to military conflict.

Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, export controls, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers in which a Fund invests. It may be impossible or impracticable for a Fund to hold, transact in or value securities of sanctioned companies, and there may be a significant decrease in the valuation of such securities. Relations between China’s Han ethnic majority and other ethnic groups in China, including Tibetans and Uighurs, are also strained and have been marked, historically, by protests and violence. These situations may cause uncertainty in the Chinese markets and may adversely affect the Chinese economy. In addition, conflict on the Korean Peninsula could adversely affect the Chinese economy. Such risks, among others, may adversely affect the value of a Fund’s investments.

Chinese Equity Markets. There are several types of Chinese equity securities, including H-shares, A-shares, B-shares, Red-Chips and/or P-Chips. The issuance of B-shares and H-shares by Chinese companies and the ability to obtain a “back-door listing” through Red-Chips or P-Chips is still regarded by the Chinese authorities as an experiment in economic reform. “Back-door listing” is a means by which a mainland Chinese company issues Red-Chips or P-Chips to obtain quick access to international listing and international capital. These share mechanisms are subject to the political and economic policies in China. In the Chinese securities markets, a small number of issuers may represent a large portion of the entire market. The Chinese securities markets also may be subject to more frequent trading halts, low trading volume and price volatility.

Hong Kong Political Risk. Hong Kong reverted to Chinese sovereignty on July 1, 1997 as a Special Administrative Region (“SAR”) of the People’s Republic of China (“PRC”) under the principle of “one country, two systems.” Although China is obligated by treaty to maintain the current capitalist economic and social system of Hong Kong through June 30, 2047, the continuation of economic and social freedoms enjoyed in Hong Kong is dependent on the government of China. Hong Kong has experienced protests and unrest related to China’s control, and tensions have increased between China and Hong Kong. Due to the interconnected nature of the Hong Kong and Chinese economies, instability in Hong Kong may adversely affect the Hong Kong and Chinese markets. Other countries’ perceptions of the degree of convergence between China and Hong Kong, such as with respect to trade, and resulting actions also may impact both economies. In addition, the Hong Kong dollar trades at a fixed exchange rate in relation to (or is “pegged” to) the U.S. dollar, which has contributed to the growth and stability of the Hong Kong economy. However, it is uncertain how long the currency peg will continue or what effect the establishment of an alternative exchange rate system would have on Hong Kong’s economy. Such a change could result in a decline in a Fund’s NAV because the NAV is denominated in U.S. dollars.

Limited Information, Legal Remedies and VIE Structure Risk. Chinese companies, including Chinese companies that are listed on U.S. exchanges, are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries. As a result, information about the Chinese securities in which the Fund invests may be less reliable or complete. Chinese companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, or for other reasons, which would significantly decrease the liquidity and value of the securities. There may be

significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies, and shareholders may have limited legal remedies. The Funds do not select investments based on investor protection considerations.

Many Chinese companies listed on U.S. exchanges use variable interest entities or “VIEs” in their structure as a result of foreign ownership restrictions. In a VIE structure, a Chinese operating company establishes a shell company in another jurisdiction to issue stock to public shareholders. When a VIE structure is used by a Chinese company to list its stock in the U.S., instead of owning the equity securities of the Chinese company, the U.S.-listed shell company directly or indirectly enters into contracts with the Chinese operating company under Chinese law. These contracts provide the U.S.-listed shell company with only economic exposure to the Chinese company and do not represent equity ownership in the operating company.

While VIEs are a longstanding practice that is well known to Chinese officials and regulators, they have not been formally recognized under Chinese law. The Chinese government has provided guidance to and placed restrictions on Chinese-based companies raising capital offshore, including through VIEs. In 2023, the China Securities Regulatory Commission (“CSRC”) released new rules that permit the use of VIE structures, provided they abide by Chinese laws and register with the CSRC. The rules, however, may cause Chinese companies to undergo greater scrutiny and add costs to VIE structures. Intervention, rulemaking or guidance by the Chinese government with respect to VIE structures or the non-enforcement of VIE-related contractual rights could significantly affect the operating company’s business in China, the enforceability of the U.S.-listed shell company’s contractual arrangements with the Chinese company and the value of the U.S.-listed stock. Further, the VIE contractual arrangement would likely be subject to Chinese law and jurisdiction, and remedies available to the U.S.-listed shell company are uncertain and could be ineffective. Any change in the operations of entities in a VIE structure, the status of VIE contractual arrangements or the legal or regulatory environment in China, generally or with respect to specific industries, could result in significant, and possibly permanent and/or total, losses to a Fund.

Risk of Investing in Developed Countries. Investment in developed country issuers will subject a Fund to legal, regulatory, political, currency, security, economic and other risks associated with developed countries. Developed countries generally tend to rely on services sectors (e.g., the financial services sector) as the primary means of economic growth. A prolonged slowdown in one or more services sectors is likely to have a negative impact on economies of certain developed countries, although economies of individual developed countries can be impacted by slowdowns in other sectors. In the past, certain developed countries have been targets of terrorism, and some geographic areas in which a Fund invests have experienced strained international relations due to territorial disputes, historical animosities, defense concerns and other security concerns. These situations may cause uncertainty in the financial markets in these countries or geographic areas and may adversely affect the performance of the issuers to which a Fund has exposure. Heavy regulation of certain markets, including labor and product markets, may have an adverse effect on certain issuers. Such regulations may negatively affect economic growth or cause prolonged periods of recession. Many developed countries are heavily indebted and face rising healthcare and retirement expenses. In addition, price fluctuations of certain commodities and regulations impacting the import of commodities may negatively affect developed country economies.

Risk of Investing in Emerging Markets. Investments in emerging market issuers may be subject to a greater risk of loss than investments in issuers located or operating in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, higher levels of inflation, social, political or economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments in emerging market countries than are typically found in more developed markets.

Some emerging market countries may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions, which would have a negative effect on the economies and financial markets of their economies. Some of these countries may impose restrictions on the exchange or export of currency or adverse currency exchange rates, and there may be a lack of available currency hedging instruments.

Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, may exacerbate unrest or violence in certain countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Companies in many emerging markets are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries, and as a result, information about the securities in which a Fund invests may be less reliable or complete. Moreover, emerging markets often have less reliable securities valuations and greater risks associated with the custody of securities than developed markets. There may be significant obstacles to obtaining information necessary for investigations into or litigation against companies, and shareholders may have limited legal remedies. A Fund’s investments are not selected based on investor protection considerations.

In addition, emerging markets often have greater risk of capital controls through such measures as taxes or interest rate control than developed markets. Certain emerging market countries may also lack the infrastructure necessary to attract large amounts of foreign trade and investment. Chronic structural public sector deficits in some countries may adversely impact a Fund’s investments.

Local securities markets in emerging market countries may trade a small number of securities and may be unable to respond effectively to changes in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. Settlement procedures in emerging market countries are frequently less developed and reliable than those in the U.S. (and other developed countries). In addition, significant delays may occur in certain markets in registering the transfer of securities. Settlement or registration problems may make it more difficult for a Fund to value its portfolio securities and could have an adverse effect on a Fund in seeking to achieve its investment objective.

There could be additional impacts on the value of a Fund as a result of sustainability risks, in particular those caused by environmental changes, social issues and governance risk. Additionally, disclosures or third-party data coverage associated with sustainability risks is generally less available or transparent in these markets.

Investments in emerging market countries may be subject to loss due to expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested in such countries.

Risk of Investing in Japan. Investing in Japanese issuers subjects a Fund to legal, regulatory, political, economic, currency, geographic and security risks that are specific to Japan. Japan’s economic growth rate has generally remained low relative to other advanced economies, and it may continue to remain low. Its economy depends heavily on international trade and government policy supporting its export market. Economic downturns or political instability in its key trading partners, which include the United States and China, could have an adverse effect on the Japanese economy. Currency fluctuations also could adversely impact Japan’s export market and its economy. If the Japanese government were to intervene in the currency market, as it has in the past, the yen’s value could fluctuate sharply and unpredictably, which could cause losses to investors.

Other risks to Japan’s economic growth and competitiveness include significant public debt and deficits as well as labor shortages due to an aging and declining population. In addition, Japan lacks many natural resources and relies heavily on imports of oil and other commodities. Price increases, shortages or volatility in commodities markets could have a negative effect on Japan’s economy. Other risks to the Japanese economy and financial markets include natural disasters and Japan’s relations with neighboring countries, which at times have been strained.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, in addition to those described under “Risk of Investing in Emerging Markets” and “Non-U.S. Securities Risk,” that are not typically associated with investing in U.S. securities, including:

■

The risk of delays in settling portfolio transactions and the risk of loss arising out of the system of share registration and custody used in Russia;

■

Risks in connection with the maintenance of a Fund’s portfolio securities and cash with foreign sub-custodians and securities depositories, including the risk that appropriate sub-custody arrangements will not be available to a Fund;

■

The risk that a Fund’s ownership rights in portfolio securities could be lost through fraud or negligence because ownership in shares of Russian companies is recorded by the companies themselves and by registrars, rather than by a central registration system;

■

The risk that a Fund may not be able to pursue claims on behalf of its shareholders because of the system of share registration and custody, and because Russian banking institutions and registrars are not guaranteed by the Russian government; and

■

The risk that various responses by other nation-states to alleged Russian cyber activity will impact Russia’s economy and Russian issuers of securities in which a Fund invests.

Russian invasion of Ukraine. Russia launched a large-scale invasion of Ukraine on February 24, 2022. The extent and duration of the military action, resulting sanctions and resulting future market disruptions, including declines in its stock markets and the value of the ruble against the U.S. dollar, are impossible to predict, but could be significant. Disruptions caused by Russian military action or other actions (including cyberattacks and espionage) or resulting actual and threatened responses to such activity, including purchasing and financing restrictions, boycotts or changes in consumer or purchaser preferences, sanctions, import and export restrictions, tariffs or cyberattacks on the Russian government, Russian companies or Russian individuals, including politicians, may impact Russia’s economy, Russian issuers of securities in which a Fund invests, or the economies of Europe as a whole. Actual and threatened responses to Russian military action may also impact

the markets for certain Russian commodities, such as oil and natural gas, as well as other sectors of the Russian economy, and are likely to have collateral impacts on such sectors across Europe and globally.

Russia Sanctions. Governments, including the U.S., the E.U., the U.K., and many other countries (collectively, the “Sanctioning Bodies”) have imposed economic sanctions on certain Russian individuals, including politicians, and Russian corporate and banking entities, including banning Russia from global payments systems that facilitate cross-border payments. In an effort to curtail Russia’s ability to finance its war effort, the Sanctioning Bodies continue to elevate these measures and may, going forward, institute broader sanctions on Russia. These sanctions, or even the threat of further sanctions, may result in the decline of the value and liquidity of Russian securities, a weakening of the ruble or other adverse consequences to the Russian economy. These sanctions could also result in the immediate freeze of Russian securities and/or funds invested in prohibited assets, impairing the ability of a Fund to buy, sell, receive or deliver those securities and/or assets.

The sanctions against certain Russian issuers include broad asset freezes and prohibitions on transacting or otherwise dealing in select issuances of debt or equity of such issuers, among others. Compliance with each of these sanctions measures has impaired, and may continue to impair, the ability of a Fund to buy, sell, hold, receive or deliver the affected securities or other securities of such issuers. A Fund may also be legally required to block (i.e., freeze) assets in a blocked account and report the accompanying exposure to Sanctioning Bodies.

Sanctions have resulted in Russia taking counter measures or retaliatory actions, which has impaired the value and liquidity of Russian securities. These retaliatory measures include the immediate freeze of Russian assets held by a Fund. Due to the freeze of these assets, including depositary receipts, a Fund may need to liquidate non-restricted assets in order to satisfy any Fund redemption orders. The liquidation of Fund assets during this time may also result in the Fund receiving substantially lower prices for its securities. Russia may implement additional retaliatory measures, which may further impair the value and liquidity of Russian securities and the ability of a Fund to receive dividend payments. Russia has issued a number of countersanctions, some of which restrict the distribution of profits by limited liability companies (e.g., dividends), and prohibits Russian persons from entering into transactions with designated persons from “unfriendly states” as well as the export of raw materials or other products from Russia to certain sanctioned persons. Russian companies may be unable to pay dividends and, if they pay dividends, a Fund may be unable to receive them.

These sanctions, the decision by Russia to suspend trading on the Moscow Exchange (MOEX) and prohibit non-resident investors from executing security sales, and other events have led index providers to remove Russian securities from indexes. Each Fund is currently restricted from trading in Russian securities, including those in its portfolio (if any), and the Underlying Indexes have removed Russian securities (if any). This disparity will also lead to increased tracking error. The inability of a Fund to trade in Russian securities may adversely affect the Fund’s ability to meet its investment objective. It is unknown when, or if, sanctions may be lifted or a Fund’s ability to trade in Russian securities will resume.

Risk of Investing in the U.K. Investing in U.K. issuers subjects a Fund to legal, regulatory, political, economic, currency, geographic and security risks that are specific to the U.K. Economic downturns or political instability in its key trading partners, which include the United States and other European countries, could have an adverse effect on the U.K. economy. Following Brexit, certain trading matters between the U.K. and the EU remain unresolved, including with respect to financial services. Continuing uncertainty regarding the U.K.’s relationship with the EU could have an adverse impact on the economy and currency of the United Kingdom. Other risks to the U.K.’s economic growth and competitiveness include high public debt and relatively low productivity.

Risk of Investing in the U.S. Investing in U.S. issuers involves legal, regulatory, political, currency, security, and economic risks that are specific to the U.S. A decrease in imports or exports, changes in trade regulations, inflation, an economic recession, financial system stress, or political turmoil, among other risks, may have an adverse effect on the U.S. economy and the securities listed on U.S. exchanges. The U.S. is also subject to the risk of natural disasters, such as droughts, earthquakes, fires and floods. U.S. security risks include acts of terrorism, internal unrest and a deterioration in relations between the U.S. and certain countries. Any of these may adversely affect the U.S. economy, financial markets or issuers.

Governmental agencies project that the U.S. will maintain elevated public debt levels for the foreseeable future. Although elevated debt levels do not necessarily indicate or cause economic problems, the costs of servicing such debt may constrain future economic growth. Circumstances could arise that could prevent the timely payment of interest or principal on U.S. government debt, such as reaching the legislative “debt ceiling.” Such non-payment would result in substantial negative consequences for the U.S. economy and the global financial system.

U.S. Economic Risk. The U.S. is a significant trading partner of, or foreign investor in, a number of countries. As a result, the economic conditions of such countries may be particularly affected by changes in the U.S. economy, such as a decrease in U.S. imports or exports, changes in trade regulations, changes in the U.S. dollar exchange rate or an economic slowdown in the U.S. Any such event may have an adverse effect on the economies of U.S. trading partners and the securities issuers in such countries, which in turn could negatively impact a Fund’s investments. Circumstances could arise that could prevent the timely payment of interest or principal on U.S. government debt, such as reaching the legislative “debt ceiling.” Such non-payment would result in substantial negative consequences for the U.S. economy and the global financial system.

Securities Lending Risk. A Fund may engage in securities lending. Securities lending involves the risk that a Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. A Fund could also lose money in the event of a

decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for a Fund.

Small-Capitalization Companies Risk. Investments in small-capitalization companies may be riskier, less liquid, more volatile and more susceptible to economic, market and industry changes than investments in large- or mid-capitalization companies. Small-capitalization companies may have more limited product lines, markets, financial resources, personnel and management experience. As a result, they generally are more vulnerable than larger companies to adverse business and economic developments. Small-capitalization companies may have a short business track record, with relatively less information available to investors. The securities of smaller companies may trade less frequently and in lower volumes than the securities of larger companies. Some securities of smaller issuers may be illiquid or restricted as to resale, and their values may have significant volatility. A Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund’s obligations.

Small Fund Risk. When a Fund’s size is small, the Fund may experience low trading volume and wide bid/ask spreads. A Fund’s performance near its inception date may not represent how the Fund will perform in the future or with a larger asset base. In addition, a Fund may face the risk of being delisted if it does not meet certain requirements set by the listing exchange. If a Fund were required to delist from the listing exchange, the Fund’s value may rapidly decline and its performance may be negatively impacted. Any resulting liquidation of a Fund could lead to elevated transaction costs for the Fund and negative tax consequences for its shareholders.

Sustainability Risk. Sustainability risk is an inclusive term to designate investment risk (probability or uncertainty of occurrence of material losses relative to the expected return of an investment) that relates to environmental, social or governance issues.

Sustainability risk around environmental issues includes, but is not limited to, climate risk, both physical and transition risk. Physical risk arises from the physical effects of climate change, acute or chronic. For example, frequent and severe climate-related events can impact products and services and supply chains. Transition risk – whether policy, technology, market or reputation risk – arises from the adjustment to a low-carbon economy in order to mitigate climate change. Risks related to social issues can include, but are not limited to, labor rights and community relations. Governance-related risks can include but are not limited to risks around board independence, ownership and control, and audit and tax management. These risks can impact an issuer’s operational effectiveness and resilience as well as its public perception and reputation, affecting its profitability and, in turn, its capital growth and ultimately impacting the value of holdings in a Fund.

These are only examples of sustainability risk factors, and sustainability risk factors do not solely determine the risk profile of the investment. The relevance, severity, materiality and time horizon of sustainability risk factors and other risks can differ significantly across Funds.

Sustainability risk can manifest itself through different existing risk types including, but not limited to, market, liquidity, concentration, credit and asset-liability mismatch risk. For example, a Fund may invest in the securities of an issuer that could face potentially reduced revenues or increased expenditures from physical climate risk (e.g., decreased production capacity due to supply chain perturbations, lower sales due to demand shocks or higher operating or capital costs) or transition risk (e.g., decreased demand for carbon-intensive products and services or increased production costs due to changing input prices). As a result, sustainability risk factors may have a material impact on an investment, may increase volatility, may affect liquidity and may have an adverse impact on the value of shares of a Fund.

The impact of those risks may be higher for Funds with particular sectoral or geographic concentrations. For example, Funds with geographic concentration in locations susceptible to adverse weather conditions where the value of the investments in the Funds may be more susceptible to adverse physical climate events, or Funds with specific sectoral concentrations, such as investing in industries or issuers with high carbon intensity or high switching costs associated with the transition to low carbon alternatives, may be more impacted by climate transition risks.

All or a combination of these factors may have an unpredictable impact on a Fund’s investments. Under normal market conditions, such events could have a material impact on the value of shares of a Fund.

Assessments of sustainability risk are specific to the asset class and to a fund’s investment objective. Different asset classes require different data and tools to apply heightened scrutiny, assess materiality, and make meaningful differentiation among issuers and assets. To the extent consistent with a Fund’s investment objective, risks are considered and risk managed concurrently, by prioritizing in part based on materiality and on the Fund’s objective.

The impacts of sustainability risk are likely to develop over time, and new sustainability risks may be identified as further data and information regarding sustainability factors and impacts become available.

Technology Companies Risk. Technology companies and companies that rely heavily on technological advances may have limited product lines, markets, financial resources and personnel. These companies may face rapid product obsolescence as well as unexpected risks and costs related to new product introduction and technological developments, such as artificial intelligence and machine learning. Technology companies may be adversely affected by disruptions to supply chains and distribution networks as well as issues at third-party partners. They are heavily dependent on patent and other intellectual property rights, and the loss or impairment of these rights may adversely affect their profitability. Technology companies may face increased government scrutiny and may be subject to adverse government or legal action. These companies also may be adversely affected by, among other things, actual or perceived security vulnerabilities or other defects in their products and services, which may result in lawsuits, government enforcement actions and other remediation costs.

Thematic Investing Risk. A Fund relies on the Index Provider to identify securities that reflect the relevant themes and sub-themes for inclusion in the Underlying Index. There is no guarantee that the Underlying Index or the Fund will reflect the intended theme and sub-theme exposures. The Fund’s performance may suffer if such securities are not correctly identified, if a theme or sub-theme develops in an unexpected manner, or if securities in the Underlying Index do not benefit from the development of a theme or sub-theme. A Fund’s performance may also be impacted if securities that are not related to the theme or sub-theme are included in the Underlying Index.

Ownership Limitations Risk. If certain aggregate and/or fund-level ownership thresholds are reached through transactions undertaken by BFA, its affiliates or a Fund, or as a result of third-party transactions or actions by an issuer or regulator, the ability of BFA and its affiliates on behalf of clients (including a Fund) to purchase or dispose of investments, exercise rights or undertake business transactions may be restricted by law, regulation or rules or otherwise impaired. The capacity of a Fund to invest in certain securities or other assets may be affected by the relevant threshold limits, and such limitations may have adverse effects on the liquidity and performance of a Fund’s portfolio holdings.

For example, ownership limits may apply to securities whose issuers operate in certain regulated industries or in certain international markets. Such limits also may apply where the investing entity (such as a Fund) is subject to corporate or regulatory ownership restrictions or invests in certain futures or other derivative transactions. In certain circumstances, aggregate and/or fund-level amounts invested or voted by BFA and its affiliates for client funds and accounts managed by BFA (including a Fund) may not exceed the relevant limits without the grant of a license or other regulatory or corporate approval, order, consent, relief or non-disapproval. However, there is no guarantee that permission will be granted or that, once granted, it will not be modified or revoked at a later date with minimal or no notice. In other cases, exceeding such thresholds may cause BFA and its affiliates, a Fund or other client accounts to suffer disadvantages or business restrictions.

Ownership limitations are highly complex. It is possible that, despite BFA’s intent to either comply with or be granted permission to exceed ownership limitations, it may inadvertently breach a limit or violate the corporate or regulatory approval, order, consent, relief or non-disapproval that was obtained.

Tracking Error Risk. A Fund that tracks an index is subject to the risk of “tracking error,” which is the divergence of a Fund’s performance from that of the Underlying Index. Tracking error may occur due to a number of factors, including differences between the securities and other assets held in a Fund’s portfolio and those included in the Underlying Index; differences in the timing and methodologies used to value securities and other assets; transaction costs and other expenses incurred by a Fund that the Underlying Index does not incur; a Fund’s holding of uninvested cash; differences in the timing of the accrual or the valuation of dividends or interest received by a Fund or distributions paid to Fund shareholders; tax gains or losses; differences between the amount and/or timing of withholding taxes on dividends reflected in the Underlying Index from a Fund’s obligation, if any, for foreign withholding taxes; the requirements for a Fund to maintain pass-through tax treatment; portfolio transactions carried out to minimize the distribution of capital gains to shareholders; the acceptance of custom baskets; changes to the Underlying Index, such as during a rebalancing or reconstitution; and impacts to a Fund of complying with certain regulatory requirements or limits. A Fund that tracks an index composed of a large number of securities or other assets may experience greater tracking error than a Fund that tracks a more narrow index. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions.

Utility Companies Risk. Utility infrastructure often requires significant capital expenditures, and utility companies may face high interest costs and difficulty in raising capital. Technological innovations may render existing equipment or products obsolete, and companies may experience difficulty in obtaining regulatory approval of new technologies. Utility operations may be disrupted by events that target or damage utility infrastructure, including natural disasters and cyber or other attacks. Utilities companies may be adversely affected by volatility in the price of certain energy resources.

Utility companies face risks from government regulation and oversight as well as from deregulation (if applicable). Regulators may monitor and control companies’ revenues and costs. There is no assurance that regulators will grant rate increases or that rate levels will be adequate to permit the payment of stock dividends or bond coupon payments. In addition, there may be regulatory restrictions on the ability of utility companies to enter new lines of business and geographic areas. Utility companies incur costs in complying with environmental and other regulations and may face significant challenges in obtaining regulatory approval for certain projects, such as nuclear power plants. Utility companies are at risk of liability for environmental harm and other types of damages. Energy conservation, climate change and other sustainability policies also may impact utility companies. Deregulation may subject companies to greater competition, may adversely affect their profitability and may lead them to engage in riskier ventures.

Valuation Risk. The price that a Fund could receive upon the sale (or other disposition) of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. The price received by a Fund also may differ from the value used by the Underlying Index (if applicable). Because non-U.S. exchanges or markets may be open on days or during time periods when a Fund does not price its shares, the value of the securities or other assets in a Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares.

In addition, for purposes of calculating a Fund’s NAV, the value of assets denominated in non-U.S. currencies (if any) is translated into U.S. dollars at the prevailing market rates. For a Fund that tracks an Underlying Index, this may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index. Authorized Participants that create or redeem Fund shares on days when a Fund

is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Portfolio Holdings Information

A description of the policies and procedures with respect to the disclosure of the Funds’ portfolio securities and other assets (as applicable) is available in the applicable Statement of Additional Information (“SAI”). Each Fund discloses its portfolio holdings daily at www.iShares.com. Fact sheets providing information about each Fund’s top holdings are posted on www.iShares.com when available and may be requested by calling 1-800-iShares (1-800-474-2737).

Management of the Funds

Investment Adviser

As investment adviser, BFA has overall responsibility for the general management and administration of the Funds. BFA provides an investment program for the Funds and manages the investment of the Funds’ assets. In seeking to achieve the Funds’ respective investment objectives, BFA uses teams of portfolio managers, investment strategists and other investment specialists and may draw upon the trading, research and expertise of its affiliates. This team approach brings together many disciplines and leverages BFA’s extensive resources.

BFA is an indirect majority-owned subsidiary of BlackRock, Inc. (“BlackRock”) and is located at 400 Howard Street, San Francisco, CA 94105. As of ____,2025, BFA and its affiliates provided investment advisory services for assets of approximately $____ trillion.

From time to time, an employee of BlackRock may express views regarding a particular security or other instrument, asset class, company, industry, or market sector. Such views are the views of only that individual as of the time expressed. They do not necessarily represent the views of BlackRock or any other person within the BlackRock organization. Such views may change at any time based upon market or other conditions, and BlackRock has no responsibility to update such views. You should not rely on any such views as investment advice or as an indication of trading intent on behalf of a Fund.

Fees and Expenses

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Funds), BFA is responsible for substantially all expenses of each Fund, except the management fees, interest expenses, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, and litigation expenses and any extraordinary expenses (as determined by a majority of the Trustees who are not “interested persons” of the Trust). Operating expenses paid by BFA under the Investment Advisory Agreement exclude Acquired Fund Fees and Expenses, if any.

A discussion regarding the basis for the approval by the Trust's Board of Trustees (the “Board”) of the Investment Advisory Agreement with BFA is available in the Funds' Form N-CSR filed with the SEC for the period ended July 31 and in the applicable financial statements and additional information documents posted at www.iShares.com.

For its investment advisory services to each Fund, for the fiscal year ended July 31, 2025, BFA was paid a management fee from each Fund, as a percentage of the Fund’s average daily net assets, net of any applicable waivers, at the annual rate set forth in the table below. If BFA has contractually agreed to waive a portion of its management fees for a Fund, the contractual waiver may be terminated prior to its expiration date only upon written agreement of the Trust and BFA. In addition, BFA may from time to time voluntarily waive and/or reimburse fees or expenses to reduce a Fund’s total annual fund operating expenses (excluding Acquired Fund Fees and Expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Conflicts of Interest

The investment activities of BFA and its affiliates (including BlackRock and its subsidiaries (collectively, the “Affiliates”)), and their respective directors, officers or employees, in managing their own accounts and other accounts, may present conflicts of interest that could disadvantage a Fund and its shareholders.

BFA and its Affiliates are involved worldwide with a broad spectrum of financial services and asset management activities and in the ordinary course of business may engage in activities in which their interests or the interests of other clients may conflict with those of a Fund. BFA and its Affiliates act, or may act, as an investor, research provider, investment manager, commodity pool operator, commodity trading advisor, financier, underwriter, adviser, trader, lender, index provider, agent and/or principal. BFA and its Affiliates may have other direct and indirect interests in securities, currencies, commodities, derivatives and other assets in which a Fund may directly or indirectly invest.

BFA and its Affiliates may engage in proprietary trading and advise accounts and other funds that have investment objectives similar to those of a Fund and/or that engage in and compete for transactions in the same or similar types of securities, currencies and other assets as are held by a Fund. This may include transactions in securities issued by other open-end and closed-end investment companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA and its Affiliates are carried out without reference to positions held directly or indirectly by a Fund. These activities may result in BFA or an Affiliate having positions in assets that are senior or junior to, or that have interests different from or adverse to, the assets held by a Fund.

A Fund may invest in securities issued by, or engage in other transactions with, entities with which an Affiliate has significant debt or equity investments or other interests. A Fund may also invest in issuances (such as debt offerings or structured notes) for which an Affiliate is compensated for providing advisory, cash management or other services. A Fund also may invest in securities of, or engage in other transactions with, entities for which an Affiliate provides or may provide research coverage or other analysis.

An Affiliate may have business relationships with, and receive compensation from, distributors, consultants or others who recommend a Fund or who engage in transactions with or for a Fund.

Neither BlackRock nor any Affiliate is under any obligation to share any investment opportunity, idea or strategy with a Fund. As a result, an Affiliate may compete with a Fund for appropriate investment opportunities. The results of a Fund’s investment activities, therefore, may differ from those of an Affiliate and of other accounts managed by an Affiliate. It is possible that a Fund could sustain losses during periods in which one or more Affiliates and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

In addition, a Fund may enter into transactions in which BFA or an Affiliate or their directors, officers, employees or clients have an adverse interest. A Fund may be adversely impacted by the effects of transactions undertaken by BFA or an Affiliate or their directors, officers, employees or clients.

From time to time, BlackRock or its advisory clients (including other funds and accounts) may, subject to compliance with applicable law, purchase and hold shares of a Fund. The price, availability, liquidity, and (in some cases) expense ratio of a Fund may be impacted by purchases and sales of the Fund by BlackRock or its advisory clients.

A Fund’s activities may be limited because of regulatory restrictions applicable to BFA or an Affiliate or their policies designed to comply with such restrictions.

Under a securities lending program approved by the Board, the Funds have retained BTC, an Affiliate of BFA, to serve as their securities lending agent to the extent that they participate in the securities lending program. For these services, the securities lending agent will receive a fee from the participating Fund based on the returns earned on the Fund’s lending activities, including investment of the cash received as collateral for the loaned securities. In addition, one or more Affiliates may be among the entities to which a Fund may lend its portfolio securities under the securities lending program.

Under an ETF Services Agreement, certain Funds have retained BlackRock Investments, LLC (the “Distributor” or “BRIL”), an Affiliate of BFA, to perform certain order processing, Authorized Participant communications, and related services in connection with the issuance and redemption of Creation Units (“ETF Services”). BRIL has engaged Citibank, N.A. (“Citibank”) as a subcontractor to provide certain ETF Services. BRIL retains a portion of the standard transaction fee received from Authorized Participants on each creation or redemption order from the Authorized Participant for the ETF Services provided. BlackRock collaborated with, and received payment from, Citibank on the design and development of the ETF Services platform. Citibank has, and from time to time may develop, additional relationships with BlackRock or funds managed by BFA and its Affiliates.

BlackRock and its Affiliates may benefit from a Fund using a BlackRock index by creating increasing acceptance in the marketplace for such indexes. BlackRock and its Affiliates are not obligated to license an index to a Fund, and no Fund is under an obligation to use a BlackRock index. The terms of a Fund’s index licensing agreement with BlackRock or its Affiliates may not be as favorable as the terms offered to other licensees.

The activities of BFA and its Affiliates and their respective directors, officers or employees may give rise to other conflicts of interest that could disadvantage a Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. Please see the SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Funds, is available free of charge by calling toll-free 1-800-iShares (1-800-474-2737) or visiting www.iShares.com.

Buying and Selling Shares

Transactions in shares of the Funds occur in the primary market and the secondary market. Primary market transactions, known as “creations” and “redemptions,” occur only between the Funds and Authorized Participants (i.e., financial institutions that are authorized to participate in such transactions), as described in the Creations and Redemptions section below.

Fund shares are listed on U.S. national securities exchanges, where they can be bought and sold throughout the trading day at market prices, like shares of other publicly traded companies. A Fund’s shares may also be available in other secondary markets, such as on non-U.S. exchanges and through funds or structured investment vehicles similar to depositary receipts. The Funds do not impose any minimum investment for Fund shares purchased on an exchange or otherwise in the secondary market.

Buying or selling Fund shares on an exchange or other secondary market generally involves two types of costs that are common in securities transactions. First, when buying or selling Fund shares through a broker, you may incur a brokerage commission and other charges. The commission is frequently a fixed amount; it may be a significant proportional cost if you are seeking to buy or sell small amounts of shares. Second, you may incur the cost of the “spread,” which is any difference between the bid price and the ask price for the shares. The spread varies over time based on a Fund’s trading volume and market liquidity. Generally, the spread is smaller if a Fund has high trading volume and market liquidity, and larger if a Fund has lower trading volume and market liquidity. The latter is often the case for newly launched or smaller funds. A Fund’s spread may also be impacted by the liquidity (or lack thereof) of the underlying securities or other assets held by the Fund, particularly for newly launched or smaller funds, or by instances of significant volatility of the underlying assets.

The U.S. national securities exchanges that list Fund shares are open for trading Monday through Friday and are closed on weekends and the following holidays (or the days on which they are observed): New Year’s Day, Martin Luther King Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Investments in Investment Companies

Section 12(d)(1) of the 1940 Act generally restricts investments by investment companies, including foreign and unregistered investment companies, in the securities of other investment companies. For example, a registered investment company (the “Acquired Fund”), such as the Funds, may not knowingly sell or otherwise dispose of any security issued by the Acquired Fund to any investment company (the “Acquiring Fund”) or any company or companies controlled by the Acquiring Fund if, immediately after such sale or disposition: (i) more than 3% of the total outstanding voting stock of the Acquired Fund is owned by the Acquiring Fund and any company or companies controlled by the Acquiring Fund, or (ii) more than 10% of the total outstanding voting stock of the Acquired Fund is owned by the Acquiring Fund and other investment companies and companies controlled by them.

Notwithstanding the foregoing, registered investment companies are permitted to invest in a Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in Rule 12d1-4 under the 1940 Act. To make such an investment in an Acquired Fund, a registered investment company must, among other things, enter into an agreement with the Trust. If an Acquired Fund invests significantly in other registered investment companies in reliance on Rule 12d1-4, an Acquiring Fund will not be permitted to rely on Rule 12d1-4 and invest in the Fund beyond the Section 12(d)(1) limits. Any investment company interested in purchasing shares of a Fund beyond the limits set forth in Section 12(d)(1) should contact BFA.

Foreign investment companies are permitted to invest in a Fund only up to the limits set forth in Section 12(d)(1), subject to any applicable SEC no-action relief.

Book Entry

Shares of the Funds are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”), which serves as the securities depository for shares of the Funds, or its nominee is the record owner of, and holds legal title to, all outstanding shares of the Funds.

Investors owning Fund shares are beneficial owners as shown on the records of DTC or its participants. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of Fund shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of Fund shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities held in book-entry or “street name” form.

Share Prices

The trading prices of a Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by various factors, such as the supply of and demand for ETF shares and the securities or other assets held by a Fund as well as other market and economic conditions.

Determination of Net Asset Value

The NAV of a Fund normally is determined once daily Monday through Friday, on each day that the New York Stock Exchange (“NYSE”) is open for trading. The NAV generally is determined as of the close of the NYSE’s regular trading hours, normally 4:00 p.m. Eastern time, based on prices at the time of closing.

Any Fund assets or liabilities that are denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers.

The NAV of a Fund is calculated by dividing the value of the Fund’s net assets (i.e., the value of its total assets, including the value of any underlying fund shares in which the Fund invests, less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent. The value of a Fund’s assets and liabilities is determined pursuant to BFA’s valuation policies and procedures. BFA has been designated by the Board as the valuation designee for each Fund pursuant to Rule 2a-5 under the Investment Company Act.

Equity securities and other equity instruments for which market quotations are readily available are valued at market value, which is generally determined using the last reported official closing price or, if a reported closing price is not available, the last traded price on the exchange or market on which the security or instrument is primarily traded at the time of valuation. Shares of underlying open-end funds (including money market funds) that are not traded on an exchange are valued at net asset value. Shares of underlying ETFs and closed-end funds that trade on exchanges are valued at their most recent market closing price.

Fixed-income securities are valued using last available bid prices or current market quotations provided by dealers or prices (including evaluated prices) supplied by the Funds’ approved independent third-party pricing services, each in accordance with BFA’s valuation policies and procedures. Pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but a Fund may hold

or transact in such securities in smaller odd lot sizes. Odd lots of securities in certain asset classes may trade at lower prices than institutional round lots, and the value ultimately realized when the securities are sold could differ from the prices used by a Fund. The amortized cost method of valuation may be used with respect to debt obligations with 60 days or less remaining to maturity unless BFA determines in good faith that such method does not represent fair value.

Generally, trading in certain instruments (e.g., non-U.S. securities, money market instruments, etc.) is substantially completed each day at various times prior to the close of the NYSE’s regular trading hours. The values of such instruments used in computing a Fund’s NAV are determined as of such times.

For certain foreign assets, a third-party vendor supplies evaluated, systematic fair value pricing based upon the movement of a proprietary multi-factor model after the relevant foreign markets have closed. This systematic fair value pricing methodology is designed to correlate the prices of foreign assets in one or more non-U.S. markets following the close of the local markets to the prices that might have prevailed as of a Fund’s pricing time.

Customized exchange-traded equity options may be valued using a mathematical model that may incorporate a number of market data factors.

When market quotations are not readily available or are believed by BFA to be unreliable, BFA will fair value a Fund’s investments in accordance with its policies and procedures. Fair value represents a good faith approximation of the value of an asset or liability. It is the amount that the Fund might reasonably expect to receive from the current sale of an asset or the cost to extinguish a liability in an arm’s-length transaction.

BFA may conclude that a market quotation is not readily available or is unreliable if:

■

An asset or liability does not have a price source due to its lack of trading or other reasons;

■

A market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value;

■

An asset or liability is thinly traded;

■

There is a significant event subsequent to the most recent market quotation; or

■

The trading market on which an instrument is listed is suspended or closed and no appropriate alternative trading market is available.

A “significant event” is deemed to occur if BFA determines, in its reasonable business judgment prior to or at the time of pricing a Fund’s assets or liabilities, that the event is likely to cause a material change to the last exchange closing price or closing market price of one or more of the Fund’s assets or liabilities.

Valuing a Fund’s investments using fair value pricing may result in prices that differ from current market valuations and that may not be the prices at which those investments could have been sold during the period for which the particular fair values were used. For an index Fund, the use of both fair value prices and current market valuations in a particular NAV calculation could result in a difference between the prices used to calculate a Fund’s NAV and the prices used by the Fund’s underlying index. This could, in turn, result in a difference between the Fund’s performance and the performance of its underlying index.

Dividends and Distributions

General Policies. A Fund generally declares and pays dividends from net investment income, if any, at least once a year. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for a Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid the imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on Fund shares are distributed on a pro rata basis to beneficial owners of the shares. Dividend payments and other distributions are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Funds.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make the DTC book-entry Dividend Reinvestment Program available to beneficial owners of Fund shares for the reinvestment of distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation. Brokers may require beneficial owners to adhere to specific procedures and timetables. If the program is used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole Fund shares purchased in the secondary market.

Note on Tax Information. The following sections summarize some of the consequences under current U.S. federal tax law of an investment in a Fund. This information is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of Fund shares. Distributions that are attributable to interest from U.S. federal government obligations may be exempt from certain state and local tax. Consult your personal tax advisor about the potential tax consequences of an investment in Fund shares under all applicable tax laws.

Taxes

As with any investment, you should consider how your investment in shares of a Fund will be taxed, including possible tax consequences when a Fund makes distributions or when you sell Fund shares. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of a Fund. There is no guarantee that shares of a Fund will receive certain regulatory or accounting treatment.

Taxes on Fund Distributions

Shareholders in a Fund will receive information after the end of each calendar year setting forth the amount of dividends and long-term capital gains distributed to them by the Fund during the prior year, if any. Likewise, the amount of tax-exempt income, if any, that a Fund distributes will be reported. Such income must be reported on the shareholder’s U.S. federal income tax return.

In general, distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

Capital Gains. Distributions from a Fund’s net investment income (other than qualified dividend income or from net tax-exempt income, if any), including distributions of income from securities lending and distributions out of a Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by a Fund of net long-term capital gains, if any, in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, regardless of how long you have held the Fund’s shares. Long-term capital gains and qualified dividend income are generally eligible for taxation at preferential rates for non-corporate shareholders. However, different preferential rates may apply depending on the type of capital gains, such as Fund distributions of certain amounts received from real estate investment trusts (“REITs”), if any.

Return of Capital. If a Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gains, if the shareholder holds shares of the Fund as capital assets. Distributions in excess of a Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to shareholders and will not constitute nontaxable returns of capital.

Qualified Dividend Income. Distributions by a Fund that qualify as qualified dividend income, if any, are taxable to you at long-term capital gain rates. Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by a Fund. Generally, qualified dividend income includes dividend income from stock issued by taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements and has not hedged its position in the stock in certain ways. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the U.S., which includes an exchange of information program, or if the stock with respect to which the dividend was paid is readily tradable on an established U.S. securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by a Fund from a RIC, if any, generally are qualified dividend income only to the extent that such dividend distributions are made out of qualified dividend income received by such RIC. Additionally, it is expected that dividends received by a Fund from a REIT, if any, and distributed to a shareholder generally will be taxable to the shareholder as ordinary income. However, a Fund may report dividends eligible for a 20% “qualified business income” deduction for non-corporate U.S. shareholders to the extent that the Fund’s income is derived from ordinary REIT dividends, reduced by allocable Fund expenses.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the relevant Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date that is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

Fund distributions, to the extent attributable to dividends from U.S. corporations, will be eligible for the dividends received deduction for Fund shareholders that are corporations, subject to certain hedging and holding requirements.

Substitute dividends received by a Fund with respect to dividends paid on securities lent out, if any, will not be qualified dividend income.

Medicare Tax. A 3.8% U.S. federal Medicare contribution tax is imposed on “net investment income,” including, but not limited to, interest, dividends, and net gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

Alternative Minimum Tax. The AMT is a separate U.S. federal tax system that operates in parallel to the regular federal income tax system but eliminates many deductions and exclusions. The AMT has different tax rates and treats as taxable certain types of income that are nontaxable for regular income tax purposes, such as the interest on certain “private activity” municipal bonds. If a taxpayer’s overall AMT liability is higher than regular income tax liability, then the taxpayer owes the regular income tax liability plus the difference between the AMT liability and the regular income tax liability.

Original Issue Discount and Inflation-Related Adjustments

Accruals of “original issue discount” on bonds that a Fund acquires at a discount and adjustments for inflation to the principal amount of an inflation-protected U.S. Treasury bond held by a Fund may be included for tax purposes in the Fund’s gross income, even though no cash attributable to such gross income has at that point been received by the Fund. In such event, the Fund may be required to make annual distributions to shareholders that exceed the cash it has otherwise received. In order to pay such distributions, the Fund may be required to raise cash by selling portfolio investments. The sale of such investments could result in capital gains to the Fund and additional capital gains distributions to Fund shareholders. In addition, any deflation-related adjustments during the taxable year to an inflation-indexed bond held by a Fund may cause amounts distributed in the taxable year as income to be characterized as a return of capital.

Market Discount Bonds

Any market discount recognized on a bond, including a tax-exempt interest bond, is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below redemption value or adjusted issue price if issued with original issue discount. To the extent that a Fund does not include the market discount in income as it accrues, gains on the Fund’s disposition of such an obligation will be treated as ordinary income rather than capital gains to the extent of the accrued market discount.

Derivatives and Other Complex Instruments

A Fund may invest in derivatives and other complex instruments, and such investments may be subject to special and complicated rules. These rules could affect whether gains and losses recognized by a Fund are treated as ordinary income or capital gains, accelerate the recognition of income to a Fund or defer a Fund’s ability to recognize losses. In addition, these rules may affect the amount, timing or character of income distributed to you by a Fund. You should consult your personal tax advisor regarding the application of these rules.

Non-U.S. Income Taxes

Dividends, interest and capital gains (if any) earned by a Fund with respect to securities issued by non-U.S. issuers may give rise to withholding, capital gains and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the U.S. may reduce or eliminate such taxes. If, at the close of a year, more than 50% of a Fund’s total assets consist of non-U.S. stocks or securities (generally, for this purpose, depositary receipts, no matter where traded, of non-U.S. companies are treated as “non-U.S.”), generally the Fund may “pass through” to you certain non-U.S. income taxes, including withholding taxes, paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income or, subject to certain limitations, a credit in calculating your U.S. federal income tax. No deduction for such taxes will be permitted to individuals in computing their alternative minimum tax liability. If a Fund does not pass through non-U.S. taxes, the Fund will be entitled to claim a deduction for certain foreign taxes that it incurs.

Under certain circumstances, if a Fund receives a refund of foreign taxes paid with respect to a prior year, the value of Fund shares could be affected or any foreign tax credits or deductions passed through to shareholders with respect to the Fund’s foreign taxes for the current year could be reduced.

If, at the close of the year, more than 50% of a Fund’s total assets consist of stocks or securities issued by non-U.S. issuers, including depositary receipts (no matter where traded) of non-U.S. companies, or, at the close of each quarter, more than 50% of a Fund’s total assets consist of shares of an Underlying Fund, the Fund may “pass-through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund or, if its assets meet these requirements, the Underlying Fund.

For purposes of foreign tax credits for U.S. shareholders of a Fund, foreign capital gains taxes may not produce associated foreign source income, limiting the availability of such credits for U.S. persons.

Non-U.S. Shareholders

If you are neither a resident nor a citizen of the U.S. or if you are a non-U.S. entity (other than a pass-through entity to the extent owned by U.S. persons), a Fund’s ordinary income dividends, if any, generally will be subject to a 30% U.S. federal withholding tax, unless a lower treaty rate applies. However, withholding tax generally will not apply to any gain or income realized by a non-U.S. shareholder upon the sale or other disposition of Fund shares or with respect to certain distributions paid to a non-U.S. shareholder and reported by the Fund as capital gain dividends, interest-related dividends or short-term capital gain dividends.

Separately, a 30% withholding tax may be imposed on Fund distributions (if any) paid to certain foreign entities, unless such entities comply, or are deemed compliant, with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S.-owned foreign investment accounts.

Backup Withholding

If you are a resident or a citizen of the U.S. and you have not provided a taxpayer identification number or social security number and made other required certifications, by law, backup withholding at a 24% rate will apply to Fund distributions and proceeds (if any).

Securities Lending

If your shares of a Fund are loaned out pursuant to a securities lending arrangement, you may lose the ability to treat Fund dividends that are paid while the shares are held by the borrower as qualified dividend income, and you may lose the ability to use non-U.S. tax credits passed through by the Fund.

Fund of Funds

If a Fund invests in an Underlying Fund, short-term capital gains earned by the Underlying Fund, if any, will be ordinary income when distributed to the Fund and will not be offset by the Fund’s capital losses. To the extent such Fund is expected to invest in an Underlying Fund, the Fund’s realized losses on sales of shares of the Underlying Fund may be indefinitely or permanently deferred as “wash sales.” Capital loss carryforwards of the Underlying Fund, if any, will not offset net capital gains of the Fund.

Taxes on the Sale of Exchange-Listed Fund Shares

Any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term capital gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares that have been held for one year or less is generally treated as a short-term capital gain or loss. However, any capital loss on a sale of Fund shares held for six months or less is treated as a long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Any such capital gains, including from sales of Fund shares or from capital gain dividends, are included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

Creations and Redemptions

Prior to being traded in the secondary market, Fund shares are “created” at NAV by Authorized Participants (i.e., market makers, large investors and other financial institutions) in block-size Creation Units or multiples thereof. Fund shares are created or redeemed only in Creation Units, and only Authorized Participants may create or redeem Creation Units with the Funds.

Each Authorized Participant is a member or participant of a clearing agency registered with the SEC and has entered into a written agreement with the Funds’ Distributor, an affiliate of BFA. The agreement allows the Authorized Participant to place orders for the purchase and redemption of Creation Units. Authorized Participants may create or redeem Creation Units for their own accounts or for customers, including, without limitation, affiliates of the Funds. Creation transactions are subject to acceptance by the Distributor and the relevant Fund.

Generally, there are three transaction methods for creating and redeeming Fund shares: in-kind securities (“in-kind”), partial cash and all cash.

In-Kind. In a creation transaction, an Authorized Participant deposits into a Fund a “creation basket,” which is a portfolio of securities or other assets designated by the Fund, as well as a cash amount. The Authorized Participant receives a specified number of Creation Units in return. In a redemption transaction, an Authorized Participant deposits Creation Units with a Fund and receives from the Fund a “redemption basket,” which is a portfolio of securities or other assets designated by the Fund, as well as a cash amount.

Partial Cash. In a creation transaction, an Authorized Participant deposits into a Fund a creation basket and a cash amount, including cash that replaces a security or other asset in the creation basket, in exchange for Creation Units. In a redemption transaction, an Authorized Participant deposits Creation Units with a Fund and receives from the Fund a redemption basket and a cash amount, including cash that replaces a security or other asset in the redemption basket.

All Cash. In a creation transaction, an Authorized Participant deposits into a Fund an amount of cash specified by the Fund in exchange for Creation Units. In a redemption transaction, an Authorized Participant deposits Creation Units with a Fund and receives from the Fund a specified amount of cash.

The creation and redemption baskets for a Fund may differ in composition, and certain iShares ETFs accept “custom baskets.” More information about custom baskets is provided in the Funds’ SAI.

Each Fund generally engages in creation and redemption transactions according to the method indicated in the table below. In certain circumstances, however, a Fund may use another transaction method (e.g., an in-kind Fund may transact partially or fully in cash).

Fund	In-Kind	Partial Cash	All Cash
iShares Breakthrough Environmental Solutions ETF		✓
iShares Cybersecurity and Tech ETF		✓
iShares Energy Storage & Materials ETF		✓
iShares Future Exponential Technologies ETF		✓
iShares Genomics Immunology and Healthcare ETF		✓
iShares Neuroscience and Healthcare ETF		✓

Fund	In-Kind	Partial Cash	All Cash
iShares Self-Driving EV and Tech ETF		✓
iShares U.S. Tech Breakthrough Multisector ETF	✓

The prices at which creations and redemptions occur are based on the next calculation of a Fund’s NAV after a creation or redemption order is tendered in an acceptable form under the Authorized Participant agreement. In the event of a system failure or other interruption, including disruptions at market makers or Authorized Participants, creation and redemption orders may not be executed according to a Fund’s instructions or may not be executed at all.

Additional information about the creation and redemption of Creation Units (including the cut-off times for the receipt of creation and redemption orders) is included in the Funds’ SAI.

The Funds do not impose restrictions on the frequency of purchases and redemptions of Fund shares directly with a Fund. The Board determined not to adopt policies and procedures designed to prevent or monitor for frequent purchases and redemptions of Fund shares because each Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, with a deadline for placing cash-related transactions no later than the close of the primary markets for the Fund’s portfolio securities. However, the Funds have taken certain measures (e.g., imposing transaction fees on purchases and redemptions of Creation Units and reserving the right to reject purchases of Creation Units under certain circumstances) to minimize the potential consequences of frequent cash purchases and redemptions by Authorized Participants, such as increased tracking error, disruption of portfolio management, dilution to the Funds, and/or increased transaction costs. Further, the vast majority of trading in Fund shares occurs on the secondary market, which does not involve the Funds directly, and such trading is unlikely to cause many of the harmful effects of frequent cash purchases or redemptions of Fund shares.

To the extent a Fund engages in in-kind transactions, the Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined in Rule 144A under the 1933 Act, will not be able to receive restricted securities eligible for resale under Rule 144A.

Because Fund shares may be created and issued on an ongoing basis, at any point during the life of a Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(a)(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Householding

Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor or its agent distributes Creation Units for the Funds on an agency basis. The Distributor does not maintain a secondary market in shares of the Funds. The Distributor has no role in determining the policies of the Funds or the securities or other assets (as applicable) that are purchased or sold by the Funds. The Distributor’s principal address is 50 Hudson Yards, New York, NY 10001.

BFA or its affiliates make payments to broker-dealers, registered investment advisers, banks or other intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, data provision services, or their making shares of the Funds available to their customers generally and in certain investment programs. Such payments, which may be significant to the intermediary, are not made by the Funds. Rather, such payments are made by BFA or its affiliates from their own resources, which come directly or indirectly in part from fees paid by the Funds. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the payments or other financial incentives the intermediary is eligible to receive.
