iSHARES® BIOTECHNOLOGY ETF

Ticker: IBBStock Exchange: Nasdaq

Investment Objective

The iShares Biotechnology ETF (the “Fund”) seeks to track the investment results of an index composed of U.S.-listed equities in the biotechnology sector.

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.

Annual Fund Operating Expenses (ongoing expenses that you pay each year as a percentage of the value of your investments)1
Management Fees	Distribution and Service (12b-1) Fees	Other Expenses2	Total Annual Fund Operating Expenses
0.44%	None	0.00%	0.44%

1Operating expenses paid by BFA under the Investment Advisory Agreement exclude acquired fund fees and expenses, if any.

2The amount rounded to 0.00%.

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
$45	$141	$246	$555

S-1

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 18% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to track the investment results of the NYSE Biotechnology Index (the “Underlying Index”), which measures the performance of U.S.-listed securities of companies that are classified according to the ICE Uniform Sector Classification schema within the Biotechnology Sub-Industry Group (as determined by ICE Data Indices, LLC or its affiliates (collectively “Index Provider” or “IDI”)) and that also meet other eligibility criteria determined by the Index Provider, including minimum market capitalization and liquidity requirements. Companies classified within the Biotechnology Sub-Industry Group include those companies that are engaged in the research and development of therapeutic treatments but that are not focused on the commercialization and mass production of pharmaceutical drugs. The Biotechnology Sub-Industry Group also includes those companies that are engaged in the production of tools or systems that enable biotechnology processes. The Underlying Index includes large-, mid- and small-capitalization companies and may change over time. As of March 31, 2025, a significant portion of the Underlying Index is represented by securities of companies in the biotechnology and healthcare industries or sectors. The components of the Underlying Index are likely to change over time.

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.

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 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.

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.

Biotechnology Industry Risk. Biotechnology companies face intense competition and potentially rapid product obsolescence. Biotechnology companies may be adversely affected by the loss or impairment of intellectual property rights or changes in government regulations.

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

S-2

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.

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.

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.

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.

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.

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.

S-3

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.

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.

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.

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 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.

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.

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; 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.

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. Fund 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.

1The Fund has added this broad-based index in response to new regulatory requirements.

2Index returns through June 20, 2021 reflect the performance of the Nasdaq Biotechnology Index (total return). Index returns beginning on June 21, 2021 reflect the performance of the ICE Biotechnology Index, which, effective as of June 21, 2021, replaced the Nasdaq Biotechnology Index (total return) as the Underlying Index of the Fund. Effective November 3, 2023, the ICE Biotechnology Index was renamed the NYSE Biotechnology Index.

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 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 has been a Portfolio Manager of the Fund since 2012. Mr. Waldron, Mr. Sietsema and Mr. White have been Portfolio Managers of the Fund since 2025.

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”).

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 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 S&P North American Expanded Technology Sector Index (the “Underlying Index”), which measures the performance of U.S.-traded stocks from the technology sector and select technology-related companies from the communication services and consumer discretionary sectors in the U.S. and Canada, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index includes companies in the following categories: producers of sophisticated computer-related devices; providers of communications equipment and internet services; producers of computer and internet software; consultants for information technology; providers of computer services; semiconductors and semiconductor equipment manufacturers; and a select company engaging in content and information creation or distribution. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2025, a significant portion of the Underlying Index is represented by securities of companies in the communication services and technology industries or sectors. 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 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 a product of SPDJI, 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

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.

S-8

Communications Companies Risk. Companies in the communications industry (“communications companies”) include telecommunications and media companies. Communications companies face risks related to cybersecurity incidents, data breaches, new technologies, substantial capital requirements, government regulation, cyclicality of revenues and earnings, obsolescence of products and services, and changes in consumer preferences and expectations, among other things. 

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.

compared with smaller-capitalization companies. The performance of large-capitalization companies could trail the overall performance of the broader securities markets.

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.

Principal Investment Strategies

The Fund seeks to track the investment results of the FTSE Nareit All Mortgage Capped Index (the “Underlying Index”), which measures the performance of the residential and commercial mortgage real estate, mortgage finance and savings associations sectors of the U.S. equity market, as defined by FTSE International Limited (the “Index Provider” or “FTSE”). The Underlying Index generally measures the performance of the residential and commercial mortgage real estate sector and generally invests all of its assets in REITs. If the number of constituents in the Underlying Index falls below 20, FTSE will consider companies from the mortgage finance and savings associations sectors for inclusion in the Underlying Index, and each company in the mortgage finance and savings associations sectors will be capped at 3% of the Underlying Index, and these sectors in the aggregate will not exceed 30% of the Underlying Index. As of March 31, 2025, approximately 100% of the market capitalization of the Underlying Index is represented by REITs. As of March 31, 2025, the Underlying Index includes 33 component securities. The components of the Underlying Index are likely to change over time.

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 FTSE, 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

Mortgage REITs Risk. Mortgage REITs are exposed to risks specific to the real estate market, including, among others, credit risk, interest rate risk and leverage risk.

Real Estate Companies Risk. Real estate companies, which include REITs, real estate holding and operating companies, and real estate management or development companies, expose investors to the risks of owning real estate directly as well as to the risks from the way that such companies operate. Real estate is highly sensitive to general and local economic conditions and can be subject to intense competition and periodic overbuilding. Other real estate risks include decreases in property values, tax increases, zoning changes, casualty or condemnation losses, environmental liabilities, regulatory limitations on rent or eviction, and defaults by borrowers or tenants. Real estate companies may be heavily invested in one geographic region, industry or property type. They also may be highly leveraged, which can magnify losses, and interest rate increases can make it difficult to obtain financing and service debt.

S-20

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.

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 the stocks held by the Fund 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 the Fund.

Mortgage Finance Companies Risk. Mortgage finance companies are subject to the credit risk of their borrowers, the risk that the value of a mortgaged property may be less than the amount owed on the property, and interest rate risk, among other risks.

S-21

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

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.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P North American Natural Resources Sector Index (the “Underlying Index”), which measures the performance of U.S.-traded stocks of natural resource-related companies in the U.S. and Canada, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index includes companies that are classified under the GICS® energy and materials sectors, excluding the chemicals industry, and steel sub-industry. The Underlying Index includes large-, mid- and small-capitalization companies and may change over time. As of March 31, 2025, a significant portion of the Underlying Index is represented by securities of companies in the energy, materials and natural resources industries or sectors. The components of the Underlying Index 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

Natural Resources Industry Risk. The value of securities issued by companies in the natural resources industry may decline for many reasons, including changes in commodity prices or government regulation, environmental damage claims, changes in exchange rates or depletion of natural resources.

North American Economic Risk. Economic events 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 the Fund invests. Political developments in the U.S., including possible termination of trade treaties with Canada and imposition of tariffs by the U.S. and Canada on the other’s products, could negatively impact the value of securities held by the Fund.

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.

Energy Companies Risk. Companies in the energy sector may be adversely affected by volatility in energy and commodity prices, lower demand, overproduction, depletion of resources, social and political unrest, war, trade disputes, government regulations and energy transition efforts, among other factors. The energy sector is cyclical and can be significantly impacted by changes in economic conditions. Some energy companies, such as those in the oil and gas sector, face substantial costs related to exploration and production and significant operational risks. Energy companies are at risk of environmental damage claims and other litigation.

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.

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-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-27

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.

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; 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.

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”).

Principal Investment Strategies

The Fund seeks to track the investment results of the ICE Exchange-Listed Preferred & Hybrid Securities Index (the “Underlying Index”), which measures the performance of a select group of exchange-listed, U.S. dollar-denominated preferred securities, hybrid securities and convertible preferred securities listed on the New York Stock Exchange (“NYSE”) or the Nasdaq Capital Market. The Underlying Index includes issuances of preferred stocks with amounts outstanding over $100 million, convertible preferred stock with at least $50 million face amount outstanding, and hybrid securities with at least $250 million face amount outstanding, that meet minimum maturity and other requirements, as applicable, as determined by ICE Data Indices, LLC (the “Index Provider” or “ICE Data”).

In general, preferred stock is a class of equity security that pays a specified dividend that must be paid before any dividends can be paid to common stockholders and takes precedence over common stock in the event of a company’s liquidation. In general, a “hybrid” security refers to a security which combines both debt and equity characteristics. In general, hybrid securities included in the Underlying Index, like traditional preferred stock, have preference over the common stock within an issuer’s capital structure, and are issued and traded in a similar manner to traditional preferred stock. Like debt securities and preferred stock (but unlike common stock), issuers of hybrid securities included in the Underlying Index may make fixed, periodic payments to the holders of such securities. Like preferred stock, issuers of hybrid securities included in the Underlying Index have the ability to defer dividend payments and to extend such securities’ maturity dates.

Although preferred stocks represent a partial ownership interest in a company, preferred stocks generally do not carry voting rights. Preferred stocks have economic characteristics similar to fixed-income securities. Preferred stocks and hybrid securities generally are issued with a fixed par value and pay dividends based on a percentage of that par value at a fixed or variable rate.

Additionally, preferred stocks and hybrid securities often have a liquidation value that generally equals the original purchase price of such security at the date of issuance. The Underlying Index may include many different categories of preferred stock and hybrid securities, such as floating and fixed rate preferreds, fixed-to-floating rate securities, callable preferreds, convertible preferreds, cumulative and non-cumulative preferreds, certain capital securities, trust preferreds or various other preferred stock and hybrid securities. The total allocation to an individual issuer across the entire Underlying Index is limited to 4.75%. The Underlying Index uses a market capitalization weighted methodology subject to certain constraints and is rebalanced monthly.

The Underlying Index may include large-, mid- or small-capitalization companies and includes preferred stocks and hybrid securities of non-U.S. issuers. As of March 31, 2025, a significant portion of the Underlying Index is represented by securities of

companies in the financials industry or sector. The components of the Underlying Index 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).

The Underlying Index is owned, maintained and administered by the Index Provider, ICE Data, 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

S-32

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.

Income Risk. The Fund’s income may decline due to falling interest rates or other factors. This can occur because the Fund may be required to invest in lower-yielding bonds when a bond in the Fund’s portfolio matures, is near maturity, is called or is prepaid, when bonds in the Underlying Index are substituted, or when the Fund otherwise needs to purchase additional bonds. The Index Provider’s substitution of bonds in the Underlying Index may occur, for example, when the time to maturity for the bond no longer matches the Underlying Index’s stated maturity guidelines.

Preferred Stock Risk. Preferred stocks are subject not only to issuer-specific and market risks generally applicable to equity securities, but also risks associated with fixed-income securities, such as interest rate risk. A company’s preferred stock, which may pay fixed or variable rates of return, generally pays dividends only after the company makes required payments to creditors, including vendors, depositors, counterparties, holders of its bonds and other fixed-income securities. As a result, the value of a company’s preferred stock will react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Preferred stock may be less liquid than many other types of securities, such as common stock, and generally has limited or no voting rights. In addition, preferred stock is subject to the risks that a company may defer or not pay dividends, and, in certain situations, may call or redeem its preferred stock or convert it to common stock. An issuer may decide to call its outstanding preferred stock in various environments based on its assessment of the relative cost of capital across the company’s capital structure. A market-wide increase in preferred stock being called may reduce the aggregate size of the preferred stock universe and the number of issuers with preferred stock outstanding. Such reductions may make it more challenging for the Fund to invest in the component securities of the Underlying Index, increasing the risk of the Fund being underinvested in the Underlying Index and thus increasing the risk of tracking error. To the extent that the Fund invests a substantial portion of its assets in convertible preferred stocks, declining common stock values may also cause the value of the Fund’s investments to decline.

Hybrid Securities Risk. Hybrid securities are subject to the risks of equity securities and risks of debt securities. The claims of holders of hybrid securities of an issuer are generally subordinated to those of holders of traditional debt securities in bankruptcy, and thus hybrid securities may be more volatile and subject to greater risk than traditional debt securities, and may in certain circumstances even be more volatile than traditional equity securities. At the same time, hybrid securities may not fully participate in gains of their issuer and thus potential returns of such securities are generally more limited than traditional equity securities, which would participate in such gains.

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. Preferred stock and hybrid securities are subordinated to debt securities in a company’s capital structure and thus are generally subject to greater risks. In the event of an issuer’s bankruptcy, equity securities have lower priority than debt securities.

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.

Credit Risk. Credit risk is the risk that an issuer, guarantor or liquidity provider of a fixed-income security may be unable or unwilling, or may be perceived as unable or unwilling, to make timely principal and/or interest payments or to otherwise honor its obligations. The credit rating assigned to a security or its issuer does not necessarily reflect the issuer’s current financial condition or an investment’s volatility or liquidity. An actual or perceived decline in an issuer’s creditworthiness may result in a decrease in the value and liquidity of its securities as well as greater price volatility, which may make it difficult to sell the securities. The Fund may be adversely affected if an investment that it holds experiences a downgrade or a default.

S-33

Financial Companies Risk. Financial services companies are subject to extensive governmental regulation and intervention, which 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, volatility in financial markets, credit rating downgrades, adverse public perception, exposure concentration and counterparty risk.

Fixed-to-Floating Rate Securities Risk. The Fund invests in fixed-to-floating rate securities, which are securities that have an initial term with a fixed dividend or coupon rate and following this initial term bear a floating rate. Securities which include a floating or variable interest rate component can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Although floating rate securities can be less sensitive to interest rate risk than fixed-rate securities, they are subject to the risks applicable to hybrid and preferred securities more generally.

Floating Rate Securities Risk. Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not reset as high, or as quickly, as comparable market interest rates, and generally carry lower yields than fixed securities of the same maturity. Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to credit risk and default risk, which could impair their value.

Illiquid Investments Risk. An illiquid investment is any investment that the 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. To the extent the Fund holds illiquid investments, the illiquid investments may reduce its returns because the Fund may be unable to transact at advantageous times or prices. In addition, if the Fund is limited in its ability to sell illiquid investments during periods when shareholders are redeeming their shares, it 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 Fund 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 Fund shares trading at a premium or discount to the Fund’s NAV.

Interest Rate Risk. Interest rate risk refers to the risk of fluctuations in the value of a fixed-income security due to changes in the general level of interest rates. Interest rate changes can be sudden and unpredictable and are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply and demand for fixed-income securities. An increase in interest rates generally will cause the value of fixed-income securities to decline. Securities

with longer maturities generally are more sensitive to interest rate changes and subject to greater fluctuations in value. Changes in interest rates may have unpredictable effects on fixed-income markets and result in heightened volatility and lower liquidity for certain instruments, which may adversely affect a Fund’s performance. During periods of very low or negative interest rates, a Fund may be unable to maintain positive returns or pay dividends to shareholders.

Principal Investment Strategies

The Fund seeks to track the investment results of the NYSE Semiconductor Index (the “Underlying Index”), which measures the performance of the equity securities of the 30 largest U.S.-listed companies that are classified according to the ICE Uniform Sector Classification schema within the semiconductors industry (as determined by ICE Data Indices, LLC or its affiliates (collectively “Index Provider” or “IDI”)). Constituents must also meet other eligibility criteria determined by the Index Provider, including minimum market capitalization and liquidity requirements. Companies classified within the semiconductors industry include companies that either manufacture materials that have electrical conductivity (semiconductors) to be used in electronic applications or utilize LED and OLED technology. The semiconductors industry also includes companies that provide services or equipment associated with semiconductors such as packaging and testing. The Underlying Index includes large- and mid-capitalization companies and may change over time. As of March 31, 2025, a significant portion of the Underlying Index is represented by securities of companies in the semiconductor and technology industries or sectors. The components of the Underlying Index are likely to change over time.

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

Semiconductor Companies Risk. The semiconductor industry is characterized by rapid technological change and product obsolescence, cyclical market patterns, price erosion, periods of over-capacity and production shortages, variations in manufacturing costs and yields, and significant expenditures for capital equipment and product development. Semiconductor companies depend significantly on third-party suppliers and the availability of raw materials and may be adversely affected by supply chain disruptions. They also may be adversely affected by the loss or impairment of intellectual property rights.

S-45

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.

S-46

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.

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; 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.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Data Center, Tower REIT and Communications Equipment Index (the “Underlying Index”), which measures the performance of stocks of U.S.-listed companies, as well as U.S.-listed American Depository Receipts (“ADRs”) of foreign companies from developed markets, involved in the ownership and management of data centers, telecommunication towers, and related equipment, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”).

The Underlying Index is a subset of the S&P Developed Broad Market Index and includes securities with a minimum float-adjusted market capitalization (“FMC”) of $300 million, a three-month Median Daily Value Traded (“MDTV”) of $2 million and may include large-, mid- or small-capitalization companies.

The Index Provider selects index constituents using a tiered approach consisting of Tier 1a, Tier 1b, and Tier 2, based on a company’s FactSet Revere Business Industry Classification System (“RBICS”) Focus Level 6 sub-industry, which defines each company’s primary line of business. The Index Provider selects companies which are classified within 17 sub-industries, which correspond with the following categories: Telecommunication Towers, Data Centers, Communications Equipment, Communications Semiconductors, and Data Storage Equipment. SPDJI classifies Tier 1a and Tier 1b companies as those belonging to the sub-industries of the Telecommunication Towers and Data Centers categories, respectively. The Index Provider classifies Tier 2 companies as those belonging to the sub-industries of the Communications Equipment, Communications Semiconductors and Data Storage Equipment categories. If there are 50 or more stocks classified as Tier 1a and Tier 1b, then all of Tier 1a and Tier 1b stocks are selected for inclusion in the Underlying Index and the Index Provider does not look to Tier 2 companies. If less than 50 stocks are classified as Tier 1a and Tier 1b, the largest eligible Tier 2 stocks, determined by the Index Provider according to the company’s FMC, are selected until the total stocks in the Underlying Index are capped at 50. The Index Provider requires the Tier 1a companies and Tier 1b companies, in aggregate, to have a minimum of 25% weight for each tier. Tier 2 companies may comprise up to 45% of the overall weight of the Underlying Index. Individual Tier 1a and Tier 1b securities are capped at 10% and individual and Tier 2 securities are capped at 4.5%. 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 December and rebalanced quarterly in March, June, and September.

As of March 31, 2025, the Underlying Index had 26 securities and a significant portion of the index constituents were represented by securities of companies in the real estate and technology

industries or sectors. The components of the Underlying Index 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

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,

S-51

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.

Real Estate Companies Risk. Real estate companies, which include , real estate holding and operating companies, and real estate management or development companies, expose investors to the risks of owning real estate directly as well as to the risks from the way that such companies operate. Real estate is highly sensitive to general and local economic conditions and can be subject to intense competition and periodic overbuilding. Other real estate risks include decreases in property values, tax increases, zoning changes, casualty or condemnation losses, environmental liabilities, regulatory limitations on rent or eviction, and defaults by borrowers or tenants. Real estate companies may be heavily invested in one geographic region, industry or property type. They also may be highly leveraged, which can magnify losses, and interest rate increases can make it difficult to obtain financing and service debt.

S-52

changes in the financial condition or credit rating of the issuer or counterparty.

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.

Principal Investment Strategies

The Fund seeks to track the investment results of the NYSE® FactSet U.S. Infrastructure Index (the “Underlying Index”), which is designed to measure the performance of equity securities of U.S. companies involved in U.S.-focused infrastructure activities (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 on the New York Stock Exchange (“NYSE”), NYSE American or Nasdaq (excluding master limited partnerships, royalty trusts, business development companies, and American depositary receipts (“ADRs”)) that are classified to be under one of the 95 infrastructure-related industries as defined by FactSet Revere Business Industry Classification System (“RBICS”). Each company in the Underlying Index is classified as either Category 1 or Category 2, where Category 1 companies are infrastructure enablers and Category 2 are infrastructure asset owners and operators.

Infrastructure enablers are potential beneficiaries of infrastructure investment in the U.S. Category 1 companies in the Underlying Index include companies in construction and engineering services, machineries and materials. Infrastructure asset owners and operators are companies associated with traditional equity infrastructure investing. Category 2 companies in the Underlying Index include companies in energy transportation and storage, railroad transportation, and utilities.

At the time of inclusion, eligible companies must derive 50% or more of their annual revenues from the U.S. The Underlying Index applies an equal weighting to Category 1 and Category 2, and within each category, an equal weighting is also applied to all individual securities.

The Underlying Index is reviewed and reconstituted annually in March. Constituent weights of the Underlying Index are rebalanced quarterly. The Underlying Index includes large-, mid-, and small- capitalization companies and may change over time. As of March 31, 2025, a significant portion of the Underlying Index is represented by securities of companies in the industrials, materials and utilities industries or sectors. The components of the Underlying Index are likely to change over time.

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. The Underlying Index is compiled utilizing RBICS classifications licensed from FactSet Research Systems, Inc. (“FactSet”). RBICS is an industry classification system defined by FactSet, which has full discretion over the classification system and is not affiliated with the Index Provider, the Fund or BFA. The classification methodology utilized for RBICS combines both market-defined information and a bottom-up approach to classify companies from all economic sectors and industries, including those in the infrastructure industry. RBICS's assignment for companies is reviewed at least once a year, with corporate actions being monitored on an ongoing basis.

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,

S-57

Infrastructure Companies Risk. Companies involved in infrastructure or infrastructure-related industries may be adversely affected by supply chain and distribution disruptions, business interruptions, third-party vendor risks, shifts in public and private capital spending levels, regulations, cyber or other attacks, volatility in commodity prices and currencies, trade disputes, scarcity of materials or parts, excess capacity, and liability claims, among other things. The performance of such companies also may be affected by technological developments, extreme weather or other catastrophic events, labor relations, government spending policies, and changes in domestic and international economies.

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.

S-58

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.

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.

Utility Companies Risk. The utilities sector is generally subject to significant government regulation and oversight, including restrictions on rates as well as environmental and other regulations. Utility companies also may face risks related to, among other things, natural disasters, cyber or other attacks, capital project funding, energy price volatility and increased competition.

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. From inception (July 17, 2024) to the most recent fiscal year end, the Fund's portfolio turnover rate was 18% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P U.S. Manufacturing Select Index (the “Underlying Index”), which was developed by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index is designed to measure the performance of equity securities of U.S.-domiciled companies that are involved in manufacturing and manufacturing-related industries and that generate a certain amount of revenues in the U.S., among other eligibility criteria, as determined by SPDJI.

The Underlying Index is a subset of the S&P United States BMI (the “Parent Index”), which includes all U.S.-domiciled companies, as determined SPDJI. All constituents of the Parent Index that meet the following eligibility criteria are included in the Underlying Index. A company must be classified in one of the following FactSet Revere Business Industry Classification System (“RBICS”) categories: Industrial Manufacturing (L2); Consumer Vehicles and Parts (L2); and a subset of the Electronic Components and Manufacturing (L2) category composed of Electronic Components (L3), Electronic Equipment Manufacturing (L3), Manufacturing Equipment and Services (L3), and Semiconductor Manufacturing Capital Equipment (L4). In the RBICS classification, L2 refers to a sector, L3 to a sub-sector, and L4 to an industry group.

Companies in the Industrial Manufacturing and Consumer Vehicles and Parts categories must derive at least 50% of their annual revenues from the U.S. Companies in an Electronic Components and Manufacturing subset must derive at least 25% of their annual revenues from the U.S. In addition, eligible constituents must have a float-adjusted market capitalization of at least $2 billion and a three-month median daily value traded of at least $5 million.

Constituents of the Underlying Index are weighted by float-adjusted market capitalization through an optimization process, with a 4% cap on individual securities. In addition, a 15% cap is applied to the Consumer Vehicles and Parts category, the Electronic Components and Manufacturing subset and each of the following subsets of the Industrial Manufacturing category:

• Aerospace and Defense Manufacturing (L3)

• Electrical Equipment and Power Systems (L3)

• Transportation Equipment Manufacturing (L3)

• Air, Liquid and Gas Control Equipment (L4)

• Factory Automation Equipment (L4)

• Industrial Machine Parts and Support Equipment (L4)

• Natural Resource and Construction Machinery Makers (L4)

• Other Machinery Manufacturing (L4)

• Tools and Outdoor Care Equipment (L4)

The Underlying Index is rebalanced quarterly and reconstituted annually.

The Underlying Index may include large-, mid- and small-capitalization companies and may change over time. As of March 31, 2025, a significant portion of the Underlying Index is represented by securities of companies in the industrials, manufacturing and technology industries or sectors.

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 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).

Summary of Principal Risks

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.

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.

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.

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.

The Fund seeks to track the investment results of the Russell 1000 Telecommunications RIC 22.5/45 Capped Index (the “Underlying Index”), which measures the performance of the telecommunications sector of the U.S. equity market, as defined by FTSE Russell (the “Index Provider” or “Russell”). The Underlying Index will include large- and mid-capitalization companies.

The Underlying Index is a subset of the Russell 1000 Index which is a float-adjusted capitalization-weighted index of equity securities issued by approximately the 1,000 largest issuers in the Russell 3000 Index. The Russell 3000 Index measures the performance of the broad U.S. equity market, as defined by Russell.

The Underlying Index uses a capping methodology to constrain at quarterly rebalance: (i) the weight of any single issuer (as determined by Russell) to a maximum of 22.5%, and (ii) the aggregate weight of all issuers that individually exceed 4.5% of the index weight to a maximum of 45%. The weight of one or more securities in the Underlying Index may exceed these constraints due to fluctuations in market value, corporate actions, or other events that change the index composition between quarterly rebalance dates.

A significant portion of the Underlying Index is represented by securities of companies in the communications industry or sector. The components of the Underlying Index 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).

The Underlying Index is sponsored by Russell, which is part of the London Stock Exchange Group and 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

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

S-69

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.

other geographic units, markets, industries, project types, or asset classes.

Operational and Technology Risks. The Fund is directly and indirectly susceptible to operational and technology risks, including those related to human errors, processing errors,

S-70

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.

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of

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

The 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. The Fund does not intend to borrow money in order to leverage its portfolio.

iShares Semiconductor ETF

European Union Disclosure

Each Fund listed below has not been categorized under the European Union (“EU”) sustainable finance disclosure regulation (“SFDR”) as an “Article 8” or “Article 9” product. In addition, each Fund’s investment strategy does not take into account the criteria for environmentally sustainable economic activities under the EU sustainable investment taxonomy regulation or principal adverse impacts (“PAIs”) on sustainability factors under the SFDR. PAIs are identified under the SFDR as the material impacts of investment decisions on sustainability factors relating to environmental, social and employee matters, respect for human rights, and anti-corruption and anti-bribery matters.

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.

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.

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. Recently, the U.S. codified the Inflation Reduction Act of 2022, which, among other things, allows for the negotiation of prescription drug prices on behalf of Medicare recipients, which may result in reduced prescription prices. This could reduce some healthcare companies' overall profitability. 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.

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.

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.

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.

Credit Risk. Credit risk is the risk that an issuer, guarantor or liquidity provider of a fixed-income security may be unable or unwilling, or may be perceived as unable or unwilling (whether by market participants, ratings agencies, pricing services or otherwise), to make timely principal and/or interest payments or to otherwise honor its obligations. It includes the risk that the security will be downgraded by a credit rating agency; generally, lower credit quality issuers present higher credit risks. The credit rating assigned to a security or its issuer does not necessarily reflect the issuer’s current financial condition or an investment’s volatility or liquidity. An actual or perceived decline in an issuer’s creditworthiness may result in a decrease in the value and liquidity of its securities as well as greater price volatility, which may make it difficult for a Fund to sell the securities and otherwise have an adverse impact on the Fund. It is possible that the ability of an issuer to meet its obligations will decline substantially during the period when a Fund owns securities of the issuer or that the issuer will default on its obligations or that the obligations of the issuer will be limited or restructured. A Fund may be adversely affected if an investment that it holds experiences a downgrade or a default.

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.

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.

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.

European Economic Risk. The Economic and Monetary Union (the “eurozone”) of 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 U.K.'s 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.

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.

Fixed-to-Floating Rate Securities Risk. Fixed-to-floating rate securities have an initial term with a fixed dividend or coupon rate and following this initial term bear a floating rate. Securities which include a floating or variable interest rate component can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their interest rates do not rise as much, or as

quickly, as interest rates in general. Conversely, floating rate securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction in income received from floating rate securities held by a Fund and may adversely affect the value of the Fund’s shares. Generally, floating rate securities carry lower yields than similar fixed rate securities. The interest rate for a floating rate security resets or adjusts periodically by reference to a benchmark interest rate. The impact of interest rate changes on floating rate investments is typically mitigated by the periodic interest rate reset of the investments. Fixed-to-floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when a Fund needs to liquidate such securities. Benchmark interest rates, such as LIBOR or the Secured Overnight Financing Rate (“SOFR”), may not accurately track market interest rates. There is no guarantee or assurance that: (i) a Fund will be able to invest in a desired amount of fixed-to-floating rate securities, (ii) a Fund will be able to buy such securities at a desirable price, or (iii) floating rate securities in which it invests or seeks to invest will be actively traded. Any or all of the foregoing, should they occur, could negatively impact the Fund.

Floating Rate Securities Risk. Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction in income received from floating rate securities held by a Fund and may adversely affect the value of the Fund’s shares. Generally, floating rate securities carry lower yields than fixed securities of the same maturity. The interest rate for a floating rate security resets or adjusts periodically by reference to a benchmark interest rate. The impact of interest rate changes on floating rate investments is typically mitigated by the periodic interest rate reset of the investments. Securities with longer durations tend to be more sensitive to interest rate changes, usually making them more volatile than securities with shorter durations. Floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such loans. Benchmark interest rates, such as the London Interbank Offered Rate (LIBOR) or the Secured Overnight Financing Rate (SOFR), may not accurately track market interest rates.

Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to credit risk and default risk, which could impair their value.

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.

Hybrid Securities Risk. Hybrid securities are securities which contain characteristics of both a debt security and an equity security. Therefore, hybrid securities are subject to the risks of equity securities and risks of debt securities. The terms of hybrid instruments may vary substantially. The claims of holders of hybrid securities of an issuer are generally subordinated to those of holders of traditional debt securities in bankruptcy, and thus hybrid securities may be more volatile and subject to greater risk than traditional debt securities, and may in certain circumstances even be more volatile than traditional equity securities. At the same time, hybrid securities may not fully participate in gains of their issuer and thus potential returns of such securities are generally more limited than traditional equity securities, which would participate in such gains. Hybrid securities may also be more limited in their rights to participate in management decisions of an issuer (such as voting for the board of directors). Certain hybrid securities may be more thinly traded and less liquid than either publicly issued equity securities or debt securities, especially hybrid securities that are “customized” to meet the needs of particular investors, potentially making it difficult for the Fund to sell such securities at a favorable price or at all. Any of these features could cause a loss in market value of hybrid securities held by a Fund or otherwise adversely affect the Fund.

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.

Income Risk. A Fund’s income may decline due to falling interest rates or other factors. This can occur because the Fund may be required to invest in lower-yielding bonds when a bond in the Fund’s portfolio matures, is near maturity, is called or is prepaid or when the Fund otherwise needs to purchase additional bonds, such as due to a substitution in the underlying index for an index fund.

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.

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. There may be increased impact on a Fund's performance to the extent that its investments are concentrated in locations that are more susceptible to adverse physical events.

Infrastructure Companies Risk. Companies involved in infrastructure or infrastructure-related activities face a number of risks, including supply chain and distribution disruptions, business interruptions, third-party vendor risks, cyber or other attacks, trade disputes, scarcity of

materials or parts, excess capacity, and volatility in commodity prices and currencies. Changes in trade restrictions and tariffs as well as broader geopolitical developments could adversely affect infrastructure companies. These companies also may be significantly affected by domestic and international economic conditions, legislative and regulatory changes, labor relations, technological developments, extreme weather or other catastrophic events. Some infrastructure companies may rely heavily on government contracts or other forms of public sector financing and thus are subject to heightened political risks, including reduced government spending or changes in policy priorities. Certain companies are subject to extensive government regulation and may incur significant compliance costs. They also may face the risk of liability for environmental damage or infrastructure failures.

Interest Rate Risk. Interest rate changes can be sudden and unpredictable and are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply and demand for fixed-income securities. Changes in interest rates may have unpredictable effects on fixed-income markets and may result in heightened volatility and lower liquidity for certain instruments, which may adversely affect a Fund’s performance. When interest rates rise, the value of fixed-income securities or other instruments sensitive to interest rates typically decreases. Duration is a measure of how sensitive a bond is to interest rate changes. Fixed-income securities with longer durations tend to be more sensitive to interest rate changes, and their prices usually are more volatile than those of shorter-duration securities. For example, if a bond has a duration of five years and interest rates rise, the price of the bond will likely decline by a greater percentage than for a bond with a one-year duration. To the extent a Fund invests a substantial portion of its assets in fixed-income securities with longer duration, rising interest rates may cause the value of the Fund’s investments to decline significantly, which would adversely affect the Fund’s performance.

In addition, changes in prevailing interest rates, particularly sudden and significant changes, may lead to fluctuations in the value of floating-rate debt securities, because the rates for those securities typically reset only periodically. Additionally, during periods of very low or negative interest rates, a Fund may be unable to maintain positive returns or pay dividends to shareholders. Under certain market conditions when interest rates are set at low levels and the market prices of portfolio securities have increased, a Fund may have a very low or even negative yield, which would cause the Fund to lose money under certain conditions.

Decreases in market-making capacity for fixed-income dealers may lead to lower trading volume, heightened volatility, wider bid-ask spreads and less transparent pricing in certain fixed-income markets.

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.

Manufacturing Companies Risk. Companies involved in manufacturing or manufacturing-related activities 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 manufacturing 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 manufacturing companies. These companies also may be significantly affected by domestic and international economic conditions, legislative and regulatory changes, and labor relations. Manufacturing 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.

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.

Mortgage Finance Companies Risk. Mortgage finance companies provide mortgages, mortgage insurance, and related services to commercial and individual borrowers. Mortgage finance companies are subject to many of the same risks as mortgage REITs, including the credit risk of their borrowers, the risk that the value of a mortgaged property may be less than the amount owed on the property, and interest rate risk.

Mortgage REITs Risk. Mortgage REITs lend money to developers and owners of properties and invest primarily in mortgages and similar real estate interests. Mortgage REITs receive interest payments from the owners of the mortgaged properties. Accordingly, mortgage REITs are subject to the credit risk of the borrowers to whom they extend funds, which is the risk that the borrower will not be able to make timely interest and principal payments on the loan to the mortgage REIT. Mortgage REITs also are subject to the risk that the value of mortgaged properties may be less than the amounts owed on the properties. If a mortgage REIT is required to foreclose on a borrower, the amount recovered in connection with the foreclosure may be less than the amount owed to the mortgage REIT.

Mortgage REITs are subject to significant interest rate risk. During periods when interest rates are declining, mortgages are often refinanced or prepaid. Refinancing or prepayment of mortgages may reduce the yield of mortgage REITs. When interest rates decline, the value of a mortgage REIT’s investment in fixed rate obligations can be expected to rise. Conversely, when interest rates rise, the value of a mortgage REIT’s investment in fixed rate obligations can be expected to decline. In addition, rising interest rates generally increase the costs of obtaining financing, which could cause the value of a mortgage REIT’s investments to decline. A mortgage REIT’s investment in adjustable rate obligations may react differently to interest rate changes than an investment in fixed rate obligations. As interest rates on adjustable rate mortgage loans are reset periodically, yields on a mortgage REIT’s investment in such loans will gradually align themselves to reflect changes in market interest rates, causing the value of such investments to fluctuate less dramatically in response to interest rate fluctuations than would investments in fixed rate obligations.

Mortgage REITs typically use leverage (and in many cases, may be highly leveraged), which increases investment risk and could adversely affect a mortgage REIT’s operations and market value in periods of rising interest rates, increased interest rate volatility, downturns in the economy, reductions in the availability of financing or deterioration in the conditions of the mortgage REIT’s mortgage-related assets.

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.

Natural Resources Industry Risk. The profitability of companies in the natural resources industry can be affected by worldwide energy prices, limits on exploration, and production spending. Companies in the natural resources industry are affected by government regulation, world events and economic conditions. Companies in the natural resources industry are at risk for environmental damage claims. Companies in the natural resources industry could be adversely affected by commodity price volatility, changes in exchange rates, imposition of import controls and increased competition. Companies in the natural resources industry may be adversely affected by depletion of natural resources, technological developments, and labor relations.

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.

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.

Preferred Stock Risk. Unlike interest payments on a debt security, dividend payments on preferred stock typically must be declared by the issuer's board of directors. An issuer's board of directors is generally not under any obligation to pay dividends (even if such dividends have accrued), and may suspend payment of dividends on preferred stock at any time. In the event an issuer of preferred stock experiences economic difficulties, the issuer's preferred stock may lose substantial value due to the reduced likelihood that the issuer's board of directors will declare dividends and the fact that the preferred stock may be subordinated to other securities of the same issuer. Certain additional risks associated with preferred stock could adversely affect investments in aFund.

Issuer Risk. Because many preferred stocks allow holders to convert the preferred stock into common stock of the issuer, market price of a preferred stock can be sensitive to changes in the value of the issuer's common stock. To the extent that a Fund invests a substantial portion of its assets in convertible preferred stocks, declining common stock values may also cause the value of the Fund's investments to decline.

Dividend Risk. There is a chance that the ability to pay dividends by the issuer of a preferred stock held by an underlying fund may deteriorate or the issuer may default (i.e., fail to make scheduled dividend payments on the preferred stock or scheduled interest payments on other obligations of the issuer not held by an underlying fund), which would negatively affect the value of any such holding.

Call Risk. Preferred stocks are subject to market volatility, and the prices of preferred stocks will fluctuate based on market demand. Preferred stocks often have call features that allow the issuer to redeem the security at its discretion.

Extension Risk. During periods of rising interest rates, certain obligations will be paid off substantially more slowly than originally anticipated, and the value of those securities may fall sharply, resulting in a decline to the Fund’s income and potentially in the value of the Fund’s investments.

Real Estate Companies Risk. Real estate companies, which include real estate investment trusts, real estate holding and operating companies, and real estate management or development companies, expose investors to the risks of owning real estate directly as well as to the risks from the way that such companies operate. Real estate companies and property values may be adversely affected by regulations and other governmental actions, including tax increases, zoning changes and other usage restrictions, environmental regulations, regulatory limitations on rent or eviction, and eminent domain.

Real estate is highly sensitive to general and local economic conditions and can be subject to intense competition and periodic overbuilding. Real estate companies may own a limited number of properties and concentrate their investments in a particular geographic region, industry or property type. Economic downturns or other adverse events (e.g., natural disasters) that affect a particular region, industry or property type may lead to decreases in property values, leasing declines and defaults by borrowers or tenants. In the event of a default, a real estate company may experience substantial delays and costs in enforcing its rights with respect to the property and protecting its investment. In addition, because real estate is relatively illiquid, a company may be constrained in its ability to diversify or liquidate its investments in response to economic conditions or other events.

Real estate companies may depend on the management skills of a few key individuals and may have limited financial resources. They may be highly leveraged, which can magnify losses, and interest rate increases can make it difficult for them, as well as borrowers and tenants, to obtain debt financing and meet payment obligations. Declining interest rates could result in increased prepayment on loans and require redeployment of capital in less desirable investments.

Certain real estate companies, such as REITs, could fail to qualify for favorable tax or regulatory treatment, which could produce adverse economic consequences for the company and its investors, including a Fund.

Reference Rate Replacement Risk. A Fund may be exposed to financial instruments that recently transitioned from, or continue to be tied to, LIBOR to determine payment obligations, financing terms, hedging strategies or investment value. The United Kingdom’s Financial Conduct Authority (“FCA”), which regulates LIBOR, has ceased publishing all LIBOR settings. In April 2023, however, the FCA announced that some USD LIBOR settings will continue to be published under a synthetic methodology until September 30, 2024 for certain legacy contracts. LIBOR, which is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities in the repurchase agreement market, has been used increasingly on a voluntary basis in new instruments and transactions. Under U.S. regulations that implement a statutory fallback mechanism to replace LIBOR, benchmark rates based on SOFR have replaced LIBOR in different categories of financial contracts.

Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. While some existing LIBOR-based instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate-setting methodology, there may be significant uncertainty regarding the effectiveness of any such alternative methodologies to replicate LIBOR. Not all existing LIBOR-based instruments may have alternative rate-setting provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. Parties to contracts, securities, or other instruments using LIBOR may disagree on transition rates or the application of transition regulation, potentially resulting in uncertainty of performance and the possibility of litigation. A Fund may have instruments linked to other interbank offered rates that may also cease to be published in the future.

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 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.

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.

Semiconductor Companies Risk. The semiconductor industry is highly cyclical, and semiconductor companies face risks related to rapid technological developments and product obsolescence, frequent new product introduction and unpredictable changes in growth rates. Capital equipment expenditures as well as research and development costs can be substantial. Semiconductor companies depend significantly on patent and intellectual property rights and may be adversely affected by the loss or impairment of these rights.

Semiconductor manufacturing processes are highly complex and sophisticated, and they are vulnerable to impurities and other disruptions that can significantly increase costs and delay production. Semiconductor companies may rely on a limited number of suppliers of the components and raw materials used in their products. Supply chain disruptions or the lack of raw materials can lead to significant operational challenges, including production halts. Semiconductor companies also face competitive challenges in attracting and retaining highly skilled personnel.

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.

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; 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.

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 March 31, 2025, BFA and its affiliates provided investment advisory services for assets of approximately $11.6 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 September 30 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 March 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.

Real Property Interests

If at least 50% of a Fund’s assets consist of U.S. real property interests, including certain REITs and U.S. real property holding corporations (as defined in the Internal Revenue Code and Treasury regulations), special rules may apply to a foreign shareholder receiving a Fund distribution. Distributions that are attributable to gains from the disposition of a U.S. real property interest will be taxable as ordinary dividends and subject to withholding at a 30% or lower treaty rate if the foreign shareholder held no more than 5% of the Fund’s shares at any time during the one-year period ending on the date of the distribution. If the foreign shareholder held more than 5% of the Fund’s shares, the distribution will be treated as income effectively connected with a trade or business within the U.S. As a result, the foreign shareholder will be subject to withholding tax at a rate of 21% and generally will be required to file a U.S. federal income tax return.

Similar consequences generally will apply to a foreign shareholder’s gain on the sale of shares of a Fund with at least 50% of its assets in U.S. real property interests, unless (i) the Fund is domestically controlled (meaning that more than 50% of the value of the Fund’s shares is held directly or indirectly by U.S. shareholders) or (ii) the foreign shareholder owns no more than 5% of the Fund’s shares at any time during the five-year period ending on the date of the sale

Shareholders that are nonresident aliens or foreign entities are urged to consult their own tax advisor about the potential tax consequences to them of an investment in a Fund whose assets include U.S. real property interests.

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).

iShares U.S. Digital Infrastructure and Real Estate ETF	✓
iShares U.S. Infrastructure ETF	✓

Fund	In-Kind	Partial	All Cash
iShares U.S. Manufacturing ETF	✓
iShares U.S. Telecommunications 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 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. Therefore, such payments or other financial incentives that are offered or made to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to
