iShares Core Conservative Allocation ETF
Ticker: AOKStock Exchange: NYSE Arca
Investment Objective
The iShares Core Conservative Allocation ETF (the Fund) seeks to track the investment results of an index composed of a portfolio of underlying equity and fixed income funds intended to represent a conservative target risk allocation strategy.
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. The Fund may incur Acquired Fund Fees and Expenses. Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund's prospectus (the Prospectus). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other series of the Trust and iShares, Inc. through November 30, 2026. The contractual waiver may be terminated prior to November 30, 2026 only upon written agreement of the Trust and BFA.
You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

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

Portfolio Turnover. The Fund and the iShares funds in which the Fund invests (each, an Underlying Fund and collectively, the Underlying Funds), may pay transaction costs, such as commissions, when they buy and sell securities (or turn over their portfolio). A higher portfolio turnover rate for the Fund or Underlying Funds may indicate higher transaction costs and may cause the Fund or Underlying Funds to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to Underlying Funds included as part of Acquired Fund Fees and Expenses), affect the Fund's performance. To the extent an Underlying Fund incurs costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund. During the most recent fiscal year, the Fund’s portfolio turnover rate was 5% of the average value of its portfolio.
S-1


Principal Investment Strategies
The Fund is a fund of funds and seeks to achieve its investment objective by investing primarily in Underlying Funds that themselves seek investment results corresponding to their own respective underlying indexes. The Underlying Funds invest primarily in distinct asset classes, such as large- or mid-capitalization U.S. or non-U.S. equity, the aggregate bond market (including allocation to international bonds as well as USD-denominated bonds) or the U.S. Treasury bond market; each such asset class has its own risk profile.
The S&P Target Risk Conservative Index (the Underlying Index) is composed of a portfolio of equity and fixed-income Underlying Funds and measures the performance of the S&P Dow Jones Indices LLC (the Index Provider or SPDJI) proprietary allocation model that is intended to represent a conservative target risk allocation strategy as defined by SPDJI. The Underlying Index seeks to emphasize exposure to fixed income, in order to produce a current income stream and avoid excessive volatility of returns. Equities are included in the Underlying Index to seek to protect long-term purchasing power. SPDJI’s estimation of a conservative target risk allocation may differ from your own.
The Fund is designed for investors seeking current income, capital preservation and avoidance of excessive volatility of returns. As of July 31, 2023, the Underlying Index included a fixed allocation of 30% of its assets in Underlying Funds that invest primarily in equity securities and 70% of its assets in Underlying Funds that invest primarily in bonds. As of July 31, 2023, the Fund invested approximately 30.75% of its assets in Underlying Funds that invest primarily in equity securities, 66.09% of its assets in Underlying Funds that invest primarily in bonds and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.
As of July 31, 2023, the Fund invested in the iShares Core International Aggregate Bond ETF, iShares Core MSCI Emerging Markets ETF, iShares Core MSCI International Developed Markets ETF, iShares Core S&P 500 ETF, iShares Core S&P Mid-Cap ETF, iShares Core S&P Small-Cap ETF, iShares Core Total USD Bond Market ETF and money market funds advised by BFA or its affiliates (BlackRock Cash Funds). BFA may add, eliminate or replace any or all Underlying Funds at any time. As of July 31, 2023, a significant portion of the Underlying Index is represented by companies in the financials industry or sector and by U.S. treasury securities. 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. Unlike many investment companies, 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 Fundand an Underlying Fund may or may not hold all of the securities in the applicable Underlying Index.
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).
The Underlying Index is a product of SPDJI, which isindependent 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(either directly or through its investments in the Underlying Funds), 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
S-2


risk is difficult to predict and may change over time. You should review each risk factor carefully.
Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s or an Underlying Fund's investment in that issuer. The degree of credit risk depends on an issuer's or counterparty's financial condition and on the terms of an obligation.
Allocation Risk. The Fund’s ability to achieve its investment objective depends upon the Index Provider's ability to develop a model that accurately assesses the Fund’s asset class allocation and selects the best mix of Underlying Funds and other ETFs. There is a risk that the Index Provider's evaluations and assumptions regarding asset classes or Underlying Funds, which are utilized as inputs in the model, may be incorrect in view of actual market conditions.
Investment in Underlying Funds Risk. The Fund invests substantially all of its assets inthe Underlying Funds, so the Fund’s investment performance is directly related to the performance of the Underlying Funds. The Fund’s NAV will change with changes in the value of the Underlying Funds and other securities in which the Fund invests based on their market valuations. An investment in the Fund will entail more costs and expenses than a direct investment in the Underlying Funds.
As the Underlying Funds, or the Fund’s allocations among the Underlying Funds, change from time to time, or to the extent that the total annual fund operating expenses of any Underlying Fund change, the weighted average operating expenses borne by the Fund may increase or decrease.
Market Risk. The Fundand the Underlying Funds 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, 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, the Underlying Funds and their investments and could result in increased premiums or discounts to the Fund’sor Underlying Fund's NAV.
Index-Related Risk. 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 disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time 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.
Affiliated Fund Risk. In managing the Fund, BFA has the ability to select Underlying Funds and substitute Underlying Funds with other exchange-traded funds (ETFs) that it believes will achieve the Fund’s objective. BFA may be subject to potential conflicts of interest in selecting Underlying Funds and substituting Underlying Funds with other ETFs because the fees paid to BFA by some Underlying Funds and other ETFs managed by BFA may be higher than the fees paid by other Underlying Funds. If an Underlying Fund or other ETF holds interests in an affiliated fund in excess of a certain amount, the Fund may be prohibited from purchasing shares of that Underlying Fund or other ETF.
Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's or an Underlying Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.
Authorized Participant Concentration Risk.  Only an Authorized Participant (as defined in the Creations and Redemptions section of this prospectus (the Prospectus)) may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.
Calculation Methodology Risk. The Index Provider relies 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 calculation methodology or sources of information will provide an accurate assessment of included components.
Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund or an Underlying Fund may call or repay the security before its stated maturity, and the Fund or an Underlying Fund may have to reinvest the proceeds in securities with lower yields, which would result in a decline in the Fund's income, or in securities with greater risks or with other less favorable features.
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 or an Underlying Fund's investments are concentrated in the securities and/or other assets of a
S-3


particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.
Currency Risk. Because the Fund's and the Underlying Funds' NAVs are determined in U.S. dollars, the Fund's NAV could decline if a currency of a non-U.S. market in which a Fund or an Underlying Fund invests depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund's NAV may change quickly and without warning.
Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund or the Underlying Funds, the Funds' or the Underlying Funds' adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.
Derivatives Risk. The Fund  or an Underlying Fund may invest in certain types of derivatives contracts, including futures, options and swaps, which can be more sensitive to changes in interest rates or to sudden fluctuations in market prices than conventional securities, which can result in greater losses to the Fund.
Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Certain Underlying Funds invest in common stocks, which generally subjecttheir holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.
Extension Risk. During periods of rising interest rates, certain debt obligations may be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in the Fund’s income and potentially in the value of the Fund’s or an Underlying Fund's investments.
Financials Sector Risk. The performance of companies in the financials sector may be adversely impacted by many factors, including, among others, changes in government regulations, economic conditions, and interest rates, credit rating downgrades, adverse public perception, exposure concentration and decreased liquidity in credit markets. The impact of changes in regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. Cybersecurity incidents and technology malfunctions and failures have become increasingly frequent and have caused significant losses to
companies in this sector, which may negatively impactan Underlying Fund.
Geographic Risk. A natural disaster could occur in a geographic region in which the Fund or an Underlying Fund invests, which could adversely affect the economy or the business operations of companies in the specific geographic region, causing an adverse impact on the Fund's or an Underlying Fund's investments in, or which are exposed to, the affected region.
High Yield Securities Risk. Securities that are rated below investment-grade (commonly referred to as junk bonds, which may include those bonds rated below BBB- by Standard & Poor's® Global Ratings, a subsidiary of S&P Global (S&P Global Ratings) and Fitch Ratings, Inc. (Fitch) or below Baa3 by Moody's Investors Service, Inc. (Moody's)), or are unrated, may be deemed speculative, may involve greater levels of risk than higher-rated securities of similar maturity and may be more likely to default.
Income Risk. The Fund's income may decline if interest rates fall. This decline in income can occur because the Fund or an Underlying Fund may subsequently invest in lower-yielding bonds when bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the Fund or an Underlying Fund otherwise needs to purchase additional bonds.
Indexing Investment Risk. The Fundand the Underlying Funds are not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.
Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund's NAV. Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.
Interest Rate Risk. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause
S-4


the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by the Fund or an Underlying Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by the Fund or an Underlying Fund. Because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities. The historically low interest rate environment in recent years heightens the risks associated with rising interest rates.
Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund or an Underlying Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.
Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.
Management Risk. As the Fund or the Underlying Funds will not fully replicate their respective indexes, they are subject to the risk that BFA's investment strategy may not produce the intended results.
Market Trading Risk. The Fund and the Underlying Funds face numerous market trading risks, including the potential lack of an active market for their shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.
Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index's allocation model will achieve its intended results or maximize returns or minimize risk, or be appropriate for every investor seeking a particular risk profile.
National Closed Market Trading Risk. To the extent that the underlying securities or other instruments held by the Fund or the Underlying Funds trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s or an Underlying Fund's shares trade is open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., the Fund’s or an Underlying Fund's quote from the closed foreign market).The impact of a closed foreign market on the Fund or an Underlying Fund is likely to be greater where a large portion of the Fund’s or an Underlying Fund's underlying securities or other instruments trade on that closed foreign
market or when the foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s or an Underlying Fund's NAV that may be greater than those experienced by other ETFs.
Non-U.S. Issuers Risk. Securities issued by non-U.S. issuers carry different risks from securities issued by U.S. issuers. These risks include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability, regulatory and economic differences, and potential restrictions on the flow of international capital.
Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fundor an Underlying Fund
may lose money due to political, economic and geographic events affecting issuers of non-U.S. securitiesor non-U.S. markets. In addition, non-U.S. securities markets 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.
Operational Risk. The Fundand the Underlying Funds are exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third parties, failed or inadequate processes and technology or systems failures. The Fund, the Underlying Funds and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.
Prepayment Risk. During periods of falling interest rates, issuers of certain debt obligations may repay principal prior to the security’s maturity, which may cause the Fund to have to reinvest in securities with lower yields or higher risk of default, resulting in a decline in the Fund’s income or return potential.
Reinvestment Risk. The Fund  or an Underlying Fund may invest a portion of its assets in short-term fixed-income instruments and, as a result, may be adversely affected if interest rates fall because they may have to invest in lower-yielding bondsas bonds mature.
Reliance on Trading Partners Risk. The Fund and certain Underlying Funds invest in countries or regions whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund's investments. Through its holdings of securities of certain issuers, the Fund is specifically exposed to Asian Economic Risk, European Economic Risk and U.S. Economic Risk.
Risk of Investing in China. Investments in Chinese securities, including certain Hong Kong-listed and U.S.-listed securities, subject the Fund or the Underlying Funds to risks specific to
S-5


China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability.
Chinese companies are also subject to the risk that Chinese authorities can intervene in their operations and structure. Internal social unrest or confrontations with neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of 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, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which the Fund invests. Incidents involving China's or the region's security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund's investments. Export growth continues to be a major driver of China's rapid economic growth. Reduction in spending on Chinese products and services, supply chain diversification, 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 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, 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 Fund is not actively managed and does not select investments based on investor protection considerations.
Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory, currency and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’sor an Underlying Fund's ownership rights in its portfolio securities as a result of the system of share registration and custody in Russia. Governments in the U.S. and many other countries have imposed economic sanctions on certain Russian individuals and Russian corporate and banking entities. A number of jurisdictions may also institute broader sanctions on Russia. Russia has issued a number of countersanctions, some of which restrict the distribution of profits by limited liability companies (e.g., dividends), and prohibit Russian persons from entering into transactions with designated persons from unfriendly states as well as the export of raw materials or other products from Russia to certain sanctioned persons. Russia launched a large-scale invasion of Ukraine on February 24, 2022. The extent and duration of the military action, resulting sanctions and resulting future market disruptions, including declines in its stock markets and the value of the ruble against the U.S. dollar, are impossible to predict, but could be significant. Disruptions caused by Russian military action or other actions (including cyberattacks and espionage) or resulting actual and threatened responses to such activity, including purchasing and financing restrictions, boycotts or changes in consumer or purchaser preferences, sanctions, import and export restrictions, tariffs or cyberattacks on the Russian government, Russian companies, or Russian individuals, including politicians, may impact Russia’s economy and Russian companies in which the Fund or an Underlying Fund invests. Actual and threatened responses to Russian military action may also impact the markets for certain Russian commodities, such as oil and natural gas, as well as other sectors of the Russian economy, and are likely to have collateral impacts on such sectors globally. Russian companies may be unable to pay dividends and, if they pay dividends, the Fund or an Underlying Fund may be unable to receive them. As a result of sanctions, the Fund is currently restricted from trading in Russian securities, including those in its portfolio, while the Underlying Index has removed Russian securities. It is unknown when, or if, sanctions may be lifted or the Fund’s ability to trade in Russian securities will resume.
Risk of Investing in Saudi Arabia. The ability of foreign investors (such as the Fundor an Underlying Fund) to invest in the securities of Saudi Arabian issuers is relatively new. Such ability could be restricted by the Saudi Arabian government at any time, and unforeseen risks could materialize with respect to foreign ownership in such securities. The economy of Saudi Arabia is dominated by petroleum exports. A sustained decrease in petroleum prices could have a negative impact on all aspects of the economy. Investments in the securities of Saudi Arabian issuers involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of the Fund’sor Underlying Fund's investments. Such heightened risks may include, among others, expropriation and/or nationalization of assets, restrictions on and
S-6


government intervention in international trade, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision making, armed conflict, crime and instability as a result of religious, ethnic and/or socioeconomic unrest. There remains the possibility that instability in the larger Middle East region could adversely impact the economy of Saudi Arabia, and there is no assurance of political stability in Saudi Arabia.
Saudi Arabia Broker Risk.  There are a number of different ways of conducting transactions in equity securities in the Saudi Arabian market.  The Fund (or an Underlying Fund) generally expects to conduct its transactions in a manner in which the Fund would not be limited by Saudi Arabian regulations to a single broker. However, there may be a limited number of brokers who can provide services to the Fund (or an Underlying Fund), which may have an adverse impact on the prices, quantity or timing of Fund (or an Underlying Fund) transactions.
Risk of Investing in the U.S. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund or the Underlying Funds has exposure.
Securities Lending Risk. The Fund  or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or the Underlying Funds may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund or the Underlying Funds 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 Fundor an Underlying Fund.
Tax Risk. Because the Fund is expected to invest in the Underlying Funds, the Fund’s realized losses on sales of shares of an Underlying Fund may be indefinitely or permanently deferred as wash sales. Distributions of short-term capital gains by an Underlying Fund will be recognized as ordinary income by the Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of an Underlying Fund, if any, would not offset net capital gains of the Fund.
Tracking Error Risk. The Fund and the Underlying Funds 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 because of differences between the securities and other instruments held in the Fund’s portfolio and those included
in the Underlying Index, pricing differences(including, as applicable, differences between a security’s price at the local market close and the Fund's or an Underlying Fund's valuation of a security at the time of calculation of the Fund's or Underlying Fund's NAV, respectively), transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual or the valuation of dividends or interest received by a Fund or distributions paid to a Fund’s or an Underlying Fund’s shareholders, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the Fund or an Underlying Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund or an Underlying Fund incurs fees and expenses, while the Underlying Index does not. The Underlying Funds are also subject to tracking error risk in seeking to track their own performance of the applicable underlying indexes.
U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of a government may cause the value of the Fund's or an Underlying Fund's U.S. Treasury obligations to decline.
Valuation Risk. The price the Fund  or an Underlying Fund could receive upon the sale of a security or other asset may differ from the Fund'sor the Underlying Fund's valuation of the security or other asset and from the value used by its underlying index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund's or an Underlying Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund's or an Underlying Fund's shares. Authorized Participants who purchase or redeem shares of the Fund or an Underlying Fund on days when the Fund or an Underlying Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Performance Information
The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide some indication of the risks of investing in the Fund by showing how the Fund’s average annual returns for 1, 5, and 10 years compare with the Underlying Index. Both assume that all dividends and distributions have been reinvested in the Fund. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. If BFA had not waived certain Fund fees during certain periods, the Fund's returns would have been lower.

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 sale 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.

Management
Investment Adviser. BlackRock Fund Advisors.
Portfolio Managers. Jennifer Hsui, Greg Savage and Paul Whitehead (the Portfolio Managers) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Ms. Hsui, Mr. Savage and Mr. Whitehead have been Portfolio Managers of the Fund since 2012, 2008 and 2022, respectively.
Purchase and Sale of Fund Shares
The Fund is an ETF. Individual shares of the Fund may only be bought and sold in the secondary market through a broker-dealer. Because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the bid-ask spread).
Tax Information
The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing
through a tax-deferred arrangement such as a 401(k) plan or an 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.

iShares Core Moderate Allocation ETF
Ticker: AOMStock Exchange: NYSE Arca
Investment Objective
The iShares Core Moderate Allocation ETF (the Fund) seeks to track the investment results of an index composed of a portfolio of underlying equity and fixed income funds intended to represent a moderate target risk allocation strategy.
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. The Fund may incur Acquired Fund Fees and Expenses. Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund's prospectus (the Prospectus). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other series of the Trust and iShares, Inc. through November 30, 2026. The contractual waiver may be terminated prior to November 30, 2026 only upon written agreement of the Trust and BFA.
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.

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:

Portfolio Turnover. The Fund and the iShares funds in which the Fund invests (each, an Underlying Fund and collectively, the Underlying Funds), may pay transaction costs, such as commissions, when they buy and sell securities (or turn over their portfolio). A higher portfolio turnover rate for the Fund or Underlying Funds may indicate higher transaction costs and may cause the Fund or Underlying Funds to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to Underlying Funds included as part of Acquired Fund Fees and Expenses), affect the Fund's performance. To the extent an Underlying Fund incurs costs from high portfolio turnover, such costs may have a
negative effect on the performance of the Fund. During the most recent fiscal year, the Fund’s portfolio turnover rate was 5% of the average value of its portfolio.
Principal Investment Strategies
The Fund is a fund of funds and seeks to achieve its investment objective by investing primarily in Underlying Funds that themselves seek investment results corresponding to their own respective underlying indexes. The Underlying Funds invest primarily in distinct asset classes, such as large- or mid-capitalization U.S. or non-U.S. equity, the aggregate bond market
S-11


(including allocation to international bonds as well as USD-denominated bonds) or the U.S. Treasury bond market; each such asset class has its own risk profile.
The S&P Target Risk Moderate Index (the Underlying Index) is composed of a portfolio of equity and fixed-income Underlying Funds and measures the performance of the S&P Dow Jones Indices LLC (the Index Provider or SPDJI) proprietary allocation model that is intended to represent a moderate target risk allocation strategy as defined by SPDJI. The Underlying Index seeks to provide significant exposure to fixed income, while also providing increased opportunity for capital growth through equities. SPDJI’s estimation of a moderate target risk allocation may differ from your own.
The Fund is designed for investors seeking current income, some capital preservation and an opportunity for moderate to low capital appreciation. As of July 31, 2023, the Underlying Index included a fixed allocation of 40% of its assets in Underlying Funds that invest primarily in equity securities and 60% of its assets in Underlying Funds that invest primarily in bonds. As of July 31, 2023, the Fund invested approximately 41.90% of its assets in Underlying Funds that invest primarily in equity securities, 57.87% of its assets in Underlying Funds that invest primarily in bonds and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.
As of July 31, 2023, the Fund invested in the iShares Core International Aggregate Bond ETF, iShares Core MSCI Emerging Markets ETF, iShares Core MSCI International Developed Markets ETF, iShares Core S&P 500 ETF, iShares Core S&P Mid-Cap ETF, iShares Core S&P Small-Cap ETF, iShares Core Total USD Bond Market ETF and money market funds advised by BFA or its affiliates (BlackRock Cash Funds). BFA may add, eliminate or replace any or all Underlying Funds at any time. As of July 31, 2023, a significant portion of the Underlying Index is represented by companies in the financials industry or sector and by U.S. treasury securities. 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. Unlike many investment companies, 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 Fundand an Underlying Fund may or may not hold all of the securities in the applicable Underlying Index.
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).
The Underlying Index is a product of SPDJI, which isindependent 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(either directly or through its investments in the Underlying Funds), 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.
Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s or an Underlying Fund's investment in that issuer. The degree of
S-12


credit risk depends on an issuer's or counterparty's financial condition and on the terms of an obligation.
Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Certain Underlying Funds invest in common stocks, which generally subjecttheir holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.
Allocation Risk. The Fund’s ability to achieve its investment objective depends upon the Index Provider's ability to develop a model that accurately assesses the Fund’s asset class allocation and selects the best mix of Underlying Funds and other ETFs. There is a risk that the Index Provider's evaluations and assumptions regarding asset classes or Underlying Funds, which are utilized as inputs in the model, may be incorrect in view of actual market conditions.
Investment in Underlying Funds Risk. The Fund invests substantially all of its assets inthe Underlying Funds, so the Fund’s investment performance is directly related to the performance of the Underlying Funds. The Fund’s NAV will change with changes in the value of the Underlying Funds and other securities in which the Fund invests based on their market valuations. An investment in the Fund will entail more costs and expenses than a direct investment in the Underlying Funds.
As the Underlying Funds, or the Fund’s allocations among the Underlying Funds, change from time to time, or to the extent that the total annual fund operating expenses of any Underlying Fund change, the weighted average operating expenses borne by the Fund may increase or decrease.
Market Risk. The Fundand the Underlying Funds 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, 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, the Underlying Funds and their investments and could result in increased premiums or discounts to the Fund’sor Underlying Fund's NAV.
Index-Related Risk. 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 disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time 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.
Affiliated Fund Risk. In managing the Fund, BFA has the ability to select Underlying Funds and substitute Underlying Funds with other exchange-traded funds (ETFs) that it believes will achieve the Fund’s objective. BFA may be subject to potential conflicts of interest in selecting Underlying Funds and substituting Underlying Funds with other ETFs because the fees paid to BFA by some Underlying Funds and other ETFs managed by BFA may be higher than the fees paid by other Underlying Funds. If an Underlying Fund or other ETF holds interests in an affiliated fund in excess of a certain amount, the Fund may be prohibited from purchasing shares of that Underlying Fund or other ETF.
Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's or an Underlying Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.
Authorized Participant Concentration Risk.  Only an Authorized Participant (as defined in the Creations and Redemptions section of this prospectus (the Prospectus)) may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund shares may be 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 ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.
Calculation Methodology Risk. The Index Provider relies 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 calculation methodology or sources of information will provide an accurate assessment of included components.
Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund or an Underlying Fund may call or repay the security before its stated maturity, and the Fund or an Underlying Fund may have to reinvest the proceeds in securities with lower yields, which would result in a decline in the Fund's income, or in securities with greater risks or with other less favorable features.
Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole,
S-13


to the extent that the Fund's or an Underlying Fund's investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.
Currency Risk. Because the Fund's and the Underlying Funds' NAVs are determined in U.S. dollars, the Fund's NAV could decline if a currency of a non-U.S. market in which a Fund or an Underlying Fund invests depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund's NAV may change quickly and without warning.
Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund or the Underlying Funds, the Funds' or the Underlying Funds' adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.
Derivatives Risk. The Fund  or an Underlying Fund may invest in certain types of derivatives contracts, including futures, options and swaps, which can be more sensitive to changes in interest rates or to sudden fluctuations in market prices than conventional securities, which can result in greater losses to the Fund.
Extension Risk. During periods of rising interest rates, certain debt obligations may be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in the Fund’s income and potentially in the value of the Fund’s or an Underlying Fund's investments.
Financials Sector Risk. The performance of companies in the financials sector may be adversely impacted by many factors, including, among others, changes in government regulations, economic conditions, and interest rates, credit rating downgrades, adverse public perception, exposure concentration and decreased liquidity in credit markets. The impact of changes in regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. Cybersecurity incidents and technology malfunctions and failures have become increasingly frequent and have caused significant losses to companies in this sector, which may negatively impactan Underlying Fund.
Geographic Risk. A natural disaster could occur in a geographic region in which the Fund or an Underlying Fund invests, which could adversely affect the economy or the business operations of
companies in the specific geographic region, causing an adverse impact on the Fund's or an Underlying Fund's investments in, or which are exposed to, the affected region.
High Yield Securities Risk. Securities that are rated below investment-grade (commonly referred to as junk bonds, which may include those bonds rated below BBB- by Standard & Poor's® Global Ratings, a subsidiary of S&P Global (S&P Global Ratings) and Fitch Ratings, Inc. (Fitch) or below Baa3 by Moody's Investors Service, Inc. (Moody's)), or are unrated, may be deemed speculative, may involve greater levels of risk than higher-rated securities of similar maturity and may be more likely to default.
Income Risk. The Fund's income may decline if interest rates fall. This decline in income can occur because the Fund or an Underlying Fund may subsequently invest in lower-yielding bonds when bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the Fund or an Underlying Fund otherwise needs to purchase additional bonds.
Indexing Investment Risk. The Fundand the Underlying Funds are not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.
Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund's NAV. Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.
Interest Rate Risk. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by the Fund or an Underlying Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by the Fund or an Underlying Fund. Because rates on certain floating rate debt
S-14


securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities. The historically low interest rate environment in recent years heightens the risks associated with rising interest rates.
Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund or an Underlying Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.
Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.
Management Risk. As the Fund or the Underlying Funds will not fully replicate their respective indexes, they are subject to the risk that BFA's investment strategy may not produce the intended results.
Market Trading Risk. The Fund and the Underlying Funds face numerous market trading risks, including the potential lack of an active market for their shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.
Mid-Capitalization Companies Risk. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments. In addition, the securities of mid-capitalization companies may be more volatile and less liquid than those of large-capitalization companies.
Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index's allocation model will achieve its intended results or maximize returns or minimize risk, or be appropriate for every investor seeking a particular risk profile.
National Closed Market Trading Risk. To the extent that the underlying securities or other instruments held by the Fund or the Underlying Funds trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s or an Underlying Fund's shares trade is open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., the Fund’s or an Underlying Fund's quote from the closed foreign market).The impact of a closed foreign market on the Fund or an Underlying Fund is likely to be greater where a large portion of the Fund’s or an Underlying Fund's underlying securities or other instruments trade on that closed foreign
market or when the foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s or an Underlying Fund's NAV that may be greater than those experienced by other ETFs.
Non-U.S. Issuers Risk. Securities issued by non-U.S. issuers carry different risks from securities issued by U.S. issuers. These risks include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability, regulatory and economic differences, and potential restrictions on the flow of international capital.
Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fundor an Underlying Fund
may lose money due to political, economic and geographic events affecting issuers of non-U.S. securitiesor non-U.S. markets. In addition, non-U.S. securities markets 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.
Operational Risk. The Fundand the Underlying Funds are exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third parties, failed or inadequate processes and technology or systems failures. The Fund, the Underlying Funds and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.
Prepayment Risk. During periods of falling interest rates, issuers of certain debt obligations may repay principal prior to the security’s maturity, which may cause the Fund to have to reinvest in securities with lower yields or higher risk of default, resulting in a decline in the Fund’s income or return potential.
Reinvestment Risk. The Fund  or an Underlying Fund may invest a portion of its assets in short-term fixed-income instruments and, as a result, may be adversely affected if interest rates fall because they may have to invest in lower-yielding bondsas bonds mature.
Reliance on Trading Partners Risk. The Fund and certain Underlying Funds invest in countries or regions whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund's investments. Through its holdings of securities of certain issuers, the Fund is specifically exposed to Asian Economic Risk, European Economic Risk and U.S. Economic Risk.
Risk of Investing in China. Investments in Chinese securities, including certain Hong Kong-listed and U.S.-listed securities, subject the Fund or the Underlying Funds to risks specific to
S-15


China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability.
Chinese companies are also subject to the risk that Chinese authorities can intervene in their operations and structure. Internal social unrest or confrontations with neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of 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, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which the Fund invests. Incidents involving China's or the region's security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund's investments. Export growth continues to be a major driver of China's rapid economic growth. Reduction in spending on Chinese products and services, supply chain diversification, 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 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, 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 Fund is not actively managed and does not select investments based on investor protection considerations.
Risk of Investing in Developed Countries. The Fund’s and the Underlying Fund's investment in developed country issuers may subject the Fund to legal, regulatory, political, currency, security, economic and other risks associated with developed countries. Developed countries tend to represent a significant portion of the global economy and have generally experienced slower economic growth than some less developed countries. Certain developed countries have experienced security concerns, such as war, terrorism and strained international relations. Incidents involving a country’s or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s or an Underlying Fund's investments. In addition, developed countries may be adversely impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.
Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory, currency and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’sor an Underlying Fund's ownership rights in its portfolio securities as a result of the system of share registration and custody in Russia. Governments in the U.S. and many other countries have imposed economic sanctions on certain Russian individuals and Russian corporate and banking entities. A number of jurisdictions may also institute broader sanctions on Russia. Russia has issued a number of countersanctions, some of which restrict the distribution of profits by limited liability companies (e.g., dividends), and prohibit Russian persons from entering into transactions with designated persons from unfriendly states as well as the export of raw materials or other products from Russia to certain sanctioned persons. Russia launched a large-scale invasion of Ukraine on February 24, 2022. The extent and duration of the military action, resulting sanctions and resulting future market disruptions, including declines in its stock markets and the value of the ruble against the U.S. dollar, are impossible to predict, but could be significant. Disruptions caused by Russian military action or other actions (including cyberattacks and espionage) or resulting actual and threatened responses to such activity, including purchasing and financing restrictions, boycotts or changes in consumer or purchaser preferences, sanctions, import and export restrictions, tariffs or cyberattacks on the Russian government, Russian companies, or Russian individuals, including politicians, may impact Russia’s economy and Russian companies in which the Fund or an Underlying Fund invests. Actual and threatened responses to Russian military action may also impact the markets for certain Russian commodities, such as oil and natural gas, as well as other sectors of the Russian economy, and are likely to have collateral impacts on such sectors globally. Russian companies may be unable to pay dividends and, if they pay dividends, the Fund or an Underlying Fund may be unable to receive them. As a result of sanctions, the Fund is currently restricted from trading in Russian securities, including those in its portfolio, while the Underlying Index has removed Russian
S-16


securities. It is unknown when, or if, sanctions may be lifted or the Fund’s ability to trade in Russian securities will resume.
Risk of Investing in Saudi Arabia. The ability of foreign investors (such as the Fundor an Underlying Fund) to invest in the securities of Saudi Arabian issuers is relatively new. Such ability could be restricted by the Saudi Arabian government at any time, and unforeseen risks could materialize with respect to foreign ownership in such securities. The economy of Saudi Arabia is dominated by petroleum exports. A sustained decrease in petroleum prices could have a negative impact on all aspects of the economy. Investments in the securities of Saudi Arabian issuers involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of the Fund’sor Underlying Fund's investments. Such heightened risks may include, among others, expropriation and/or nationalization of assets, restrictions on and government intervention in international trade, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision making, armed conflict, crime and instability as a result of religious, ethnic and/or socioeconomic unrest. There remains the possibility that instability in the larger Middle East region could adversely impact the economy of Saudi Arabia, and there is no assurance of political stability in Saudi Arabia.
Saudi Arabia Broker Risk.  There are a number of different ways of conducting transactions in equity securities in the Saudi Arabian market.  The Fund (or an Underlying Fund) generally expects to conduct its transactions in a manner in which the Fund would not be limited by Saudi Arabian regulations to a single broker. However, there may be a limited number of brokers who can provide services to the Fund (or an Underlying Fund), which may have an adverse impact on the prices, quantity or timing of Fund (or an Underlying Fund) transactions.
Risk of Investing in the U.S. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund or the Underlying Funds has exposure.
Securities Lending Risk. The Fund  or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or the Underlying Funds may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund or the Underlying Funds 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 Fundor an Underlying Fund.
Tax Risk. Because the Fund is expected to invest in the Underlying Funds, the Fund’s realized losses on sales of shares of an Underlying Fund may be indefinitely or permanently deferred as wash sales. Distributions of short-term capital gains by an Underlying Fund will be recognized as ordinary income by the
Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of an Underlying Fund, if any, would not offset net capital gains of the Fund.
Tracking Error Risk. The Fund and the Underlying Funds 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 because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences(including, as applicable, differences between a security’s price at the local market close and the Fund's or an Underlying Fund's valuation of a security at the time of calculation of the Fund's or Underlying Fund's NAV, respectively), transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual or the valuation of dividends or interest received by a Fund or distributions paid to a Fund’s or an Underlying Fund’s shareholders, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the Fund or an Underlying Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund or an Underlying Fund incurs fees and expenses, while the Underlying Index does not. The Underlying Funds are also subject to tracking error risk in seeking to track their own performance of the applicable underlying indexes.
U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of a government may cause the value of the Fund's or an Underlying Fund's U.S. Treasury obligations to decline.
Valuation Risk. The price the Fund  or an Underlying Fund could receive upon the sale of a security or other asset may differ from the Fund'sor the Underlying Fund's valuation of the security or other asset and from the value used by its underlying index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund's or an Underlying Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund's or an Underlying Fund's shares. Authorized Participants who purchase or redeem shares of the Fund or an Underlying Fund on days when the Fund or an Underlying Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Performance Information
The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide some indication of the risks of investing in the Fund by showing how the Fund’s average annual returns for 1, 5, and 10 years compare with the Underlying Index. Both assume that all dividends and distributions have been reinvested in the Fund. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. If BFA had not waived certain Fund fees during certain periods, the Fund's returns would have been lower.

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 sale 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.

Management
Investment Adviser. BlackRock Fund Advisors.
Portfolio Managers. Jennifer Hsui, Greg Savage and Paul Whitehead (the Portfolio Managers) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Ms. Hsui, Mr. Savage and Mr. Whitehead have been Portfolio Managers of the Fund since 2012, 2008 and 2022, respectively.
Purchase and Sale of Fund Shares
The Fund is an ETF. Individual shares of the Fund may only be bought and sold in the secondary market through a broker-dealer. Because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the bid-ask spread).
Tax Information
The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing
through a tax-deferred arrangement such as a 401(k) plan or an 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.

iShares Core Growth Allocation ETF
Ticker: AORStock Exchange: NYSE Arca
Investment Objective
The iShares Core Growth Allocation ETF (the Fund) seeks to track the investment results of an index composed of a portfolio of underlying equity and fixed income funds intended to represent a growth allocation target risk strategy.
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. The Fund may incur Acquired Fund Fees and Expenses. Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund's prospectus (the Prospectus). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other series of the Trust and iShares, Inc. through November 30, 2026. The contractual waiver may be terminated prior to November 30, 2026 only upon written agreement of the Trust and BFA.
You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

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

Portfolio Turnover. The Fund and the iShares funds in which the Fund invests (each, an Underlying Fund and collectively, the Underlying Funds), may pay transaction costs, such as commissions, when they buy and sell securities (or turn over their portfolio). A higher portfolio turnover rate for the Fund or Underlying Funds may indicate higher transaction costs and may cause the Fund or Underlying Funds to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to Underlying Funds included as part of Acquired Fund Fees and Expenses), affect the Fund's performance. To the extent an Underlying Fund incurs costs from high portfolio turnover, such costs may have a
negative effect on the performance of the Fund. During the most recent fiscal year, the Fund’s portfolio turnover rate was 6% of the average value of its portfolio.
Principal Investment Strategies
The Fund is a fund of funds and seeks to achieve its investment objective by investing primarily in Underlying Funds that themselves seek investment results corresponding to their own respective underlying indexes. The Underlying Funds invest primarily in distinct asset classes, such as large- or mid-capitalization U.S. or non-U.S. equity, the aggregate bond market
S-21


(including USD-denominated bonds) or the U.S. Treasury bond market; each such asset class has its own risk profile.
The S&P Target Risk Growth Index (the Underlying Index) is composed of a portfolio of equity and fixed-income Underlying Funds and measures the performance of the S&P Dow Jones Indices LLC (the Index Provider or SPDJI) proprietary allocation model that is intended to represent a growth target risk allocation strategy as defined by SPDJI. The Underlying Index seeks to provide increased exposure to equities, while also using some fixed income exposure to dampen risk. SPDJI’s estimation of a growth target risk allocation may differ from your own.
The Fund is designed for investors seeking moderate capital appreciation and some opportunity for current income and capital preservation. As of July 31, 2023, the Underlying Index included a fixed allocation of 60% of its assets in Underlying Funds that invest primarily in equity securities and 40% of its assets in Underlying Funds that invest primarily in bonds. As of July 31, 2023, the Fund invested approximately 61.84% of its assets in Underlying Funds that invest primarily in equity securities, 37.98% of its assets in Underlying Funds that invest primarily in bonds and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.
As of July 31, 2023, the Fund invested in the iShares Core International Aggregate Bond ETF, iShares Core MSCI Emerging Markets ETF, iShares Core MSCI International Developed Markets ETF, iShares Core S&P 500 ETF, iShares Core S&P Mid-Cap ETF, iShares Core S&P Small-Cap ETF, iShares Core Total USD Bond Market ETF and money market funds advised by BFA or its affiliates (BlackRock Cash Funds). BFA may add, eliminate or replace any or all Underlying Funds at any time. As of July 31, 2023, a significant portion of the Underlying Index is represented by companies in the financials industry or sector and by U.S. treasury securities. 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. Unlike many investment companies, 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 Fundand an Underlying Fund may or may not hold all of the securities in the applicable Underlying Index.
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).
The Underlying Index is a product of SPDJI, which isindependent 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(either directly or through its investments in the Underlying Funds), 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.
Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Certain Underlying Funds invest in common stocks, which generally subjecttheir holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.
S-22


Allocation Risk. The Fund’s ability to achieve its investment objective depends upon the Index Provider's ability to develop a model that accurately assesses the Fund’s asset class allocation and selects the best mix of Underlying Funds and other ETFs. There is a risk that the Index Provider's evaluations and assumptions regarding asset classes or Underlying Funds, which are utilized as inputs in the model, may be incorrect in view of actual market conditions.
Investment in Underlying Funds Risk. The Fund invests substantially all of its assets inthe Underlying Funds, so the Fund’s investment performance is directly related to the performance of the Underlying Funds. The Fund’s NAV will change with changes in the value of the Underlying Funds and other securities in which the Fund invests based on their market valuations. An investment in the Fund will entail more costs and expenses than a direct investment in the Underlying Funds.
As the Underlying Funds, or the Fund’s allocations among the Underlying Funds, change from time to time, or to the extent that the total annual fund operating expenses of any Underlying Fund change, the weighted average operating expenses borne by the Fund may increase or decrease.
Market Risk. The Fundand the Underlying Funds 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, 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, the Underlying Funds and their investments and could result in increased premiums or discounts to the Fund’sor Underlying Fund's NAV.
Index-Related Risk. 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 disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time 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.
Affiliated Fund Risk. In managing the Fund, BFA has the ability to select Underlying Funds and substitute Underlying Funds with other exchange-traded funds (ETFs) that it believes will achieve the Fund’s objective. BFA may be subject to potential conflicts of interest in selecting Underlying Funds and substituting Underlying Funds with other ETFs because the fees paid to BFA by some Underlying Funds and other ETFs managed by BFA may be higher
than the fees paid by other Underlying Funds. If an Underlying Fund or other ETF holds interests in an affiliated fund in excess of a certain amount, the Fund may be prohibited from purchasing shares of that Underlying Fund or other ETF.
Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's or an Underlying Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.
Authorized Participant Concentration Risk.  Only an Authorized Participant (as defined in the Creations and Redemptions section of this prospectus (the Prospectus)) may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund shares may be 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 ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.
Calculation Methodology Risk. The Index Provider relies 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 calculation methodology or sources of information will provide an accurate assessment of included components.
Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund or an Underlying Fund may call or repay the security before its stated maturity, and the Fund or an Underlying Fund may have to reinvest the proceeds in securities with lower yields, which would result in a decline in the Fund's income, or in securities with greater risks or with other less favorable features.
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 or an Underlying Fund's investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.
Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s or an Underlying Fund's investment in that issuer. The degree of
S-23


credit risk depends on an issuer's or counterparty's financial condition and on the terms of an obligation.
Currency Risk. Because the Fund's and the Underlying Funds' NAVs are determined in U.S. dollars, the Fund's NAV could decline if a currency of a non-U.S. market in which a Fund or an Underlying Fund invests depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund's NAV may change quickly and without warning.
Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund or the Underlying Funds, the Funds' or the Underlying Funds' adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.
Derivatives Risk. The Fund  or an Underlying Fund may invest in certain types of derivatives contracts, including futures, options and swaps, which can be more sensitive to changes in interest rates or to sudden fluctuations in market prices than conventional securities, which can result in greater losses to the Fund.
Extension Risk. During periods of rising interest rates, certain debt obligations may be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in the Fund’s income and potentially in the value of the Fund’s or an Underlying Fund's investments.
Financials Sector Risk. The performance of companies in the financials sector may be adversely impacted by many factors, including, among others, changes in government regulations, economic conditions, and interest rates, credit rating downgrades, adverse public perception, exposure concentration and decreased liquidity in credit markets. The impact of changes in regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. Cybersecurity incidents and technology malfunctions and failures have become increasingly frequent and have caused significant losses to companies in this sector, which may negatively impactan Underlying Fund.
Geographic Risk. A natural disaster could occur in a geographic region in which the Fund or an Underlying Fund invests, which could adversely affect the economy or the business operations of companies in the specific geographic region, causing an adverse impact on the Fund's or an Underlying Fund's investments in, or which are exposed to, the affected region.
High Yield Securities Risk. Securities that are rated below investment-grade (commonly referred to as junk bonds, which may include those bonds rated below BBB- by Standard & Poor's® Global Ratings, a subsidiary of S&P Global (S&P Global Ratings) and Fitch Ratings, Inc. (Fitch) or below Baa3 by Moody's Investors Service, Inc. (Moody's)), or are unrated, may be deemed speculative, may involve greater levels of risk than higher-rated securities of similar maturity and may be more likely to default.
Income Risk. The Fund's income may decline if interest rates fall. This decline in income can occur because the Fund or an Underlying Fund may subsequently invest in lower-yielding bonds when bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the Fund or an Underlying Fund otherwise needs to purchase additional bonds.
Indexing Investment Risk. The Fundand the Underlying Funds are not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.
Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund's NAV. Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.
Interest Rate Risk. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by the Fund or an Underlying Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by the Fund or an Underlying Fund. Because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt
S-24


securities. The historically low interest rate environment in recent years heightens the risks associated with rising interest rates.
Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund or an Underlying Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.
Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.
Management Risk. As the Fund or the Underlying Funds will not fully replicate their respective indexes, they are subject to the risk that BFA's investment strategy may not produce the intended results.
Market Trading Risk. The Fund and the Underlying Funds face numerous market trading risks, including the potential lack of an active market for their shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.
Mid-Capitalization Companies Risk. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments. In addition, the securities of mid-capitalization companies may be more volatile and less liquid than those of large-capitalization companies.
Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index's allocation model will achieve its intended results or maximize returns or minimize risk, or be appropriate for every investor seeking a particular risk profile.
National Closed Market Trading Risk. To the extent that the underlying securities or other instruments held by the Fund or the Underlying Funds trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s or an Underlying Fund's shares trade is open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., the Fund’s or an Underlying Fund's quote from the closed foreign market).The impact of a closed foreign market on the Fund or an Underlying Fund is likely to be greater where a large portion of the Fund’s or an Underlying Fund's underlying securities or other instruments trade on that closed foreign market or when the foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s or an Underlying Fund's NAV that may be greater than those experienced by other ETFs.
Non-U.S. Issuers Risk. Securities issued by non-U.S. issuers carry different risks from securities issued by U.S. issuers. These risks include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability, regulatory and economic differences, and potential restrictions on the flow of international capital.
Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund or an Underlying Fund may lose money due to political, economic and geographic events affecting issuers of non-U.S. securities or non-U.S. markets. In addition, non-U.S. securities markets 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.
Operational Risk. The Fundand the Underlying Funds are exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third parties, failed or inadequate processes and technology or systems failures. The Fund, the Underlying Funds and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.
Prepayment Risk. During periods of falling interest rates, issuers of certain debt obligations may repay principal prior to the security’s maturity, which may cause the Fund to have to reinvest in securities with lower yields or higher risk of default, resulting in a decline in the Fund’s income or return potential.
Reinvestment Risk. The Fund  or an Underlying Fund may invest a portion of its assets in short-term fixed-income instruments and, as a result, may be adversely affected if interest rates fall because they may have to invest in lower-yielding bondsas bonds mature.
Reliance on Trading Partners Risk. The Fund and certain Underlying Funds invest in countries or regions whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund's investments. Through its holdings of securities of certain issuers, the Fund is specifically exposed to Asian Economic Risk, European Economic Risk and U.S. Economic Risk.
Risk of Investing in China. Investments in Chinese securities, including certain Hong Kong-listed and U.S.-listed securities, subject the Fund or the Underlying Funds to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of
S-25


economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability.
Chinese companies are also subject to the risk that Chinese authorities can intervene in their operations and structure. Internal social unrest or confrontations with neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of 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, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which the Fund invests. Incidents involving China's or the region's security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund's investments. Export growth continues to be a major driver of China's rapid economic growth. Reduction in spending on Chinese products and services, supply chain diversification, 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 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, 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 Fund is not actively managed and does not select investments based on investor protection considerations.
Risk of Investing in Developed Countries. The Fund’s and the Underlying Fund's investment in developed country issuers may subject the Fund to legal, regulatory, political, currency, security, economic and other risks associated with developed countries. Developed countries tend to represent a significant portion of the global economy and have generally experienced slower economic growth than some less developed countries. Certain developed countries have experienced security concerns, such as war, terrorism and strained international relations. Incidents involving a country’s or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s or an Underlying Fund's investments. In addition, developed countries may be adversely impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.
Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory, currency and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’sor an Underlying Fund's ownership rights in its portfolio securities as a result of the system of share registration and custody in Russia. Governments in the U.S. and many other countries have imposed economic sanctions on certain Russian individuals and Russian corporate and banking entities. A number of jurisdictions may also institute broader sanctions on Russia. Russia has issued a number of countersanctions, some of which restrict the distribution of profits by limited liability companies (e.g., dividends), and prohibit Russian persons from entering into transactions with designated persons from unfriendly states as well as the export of raw materials or other products from Russia to certain sanctioned persons. Russia launched a large-scale invasion of Ukraine on February 24, 2022. The extent and duration of the military action, resulting sanctions and resulting future market disruptions, including declines in its stock markets and the value of the ruble against the U.S. dollar, are impossible to predict, but could be significant. Disruptions caused by Russian military action or other actions (including cyberattacks and espionage) or resulting actual and threatened responses to such activity, including purchasing and financing restrictions, boycotts or changes in consumer or purchaser preferences, sanctions, import and export restrictions, tariffs or cyberattacks on the Russian government, Russian companies, or Russian individuals, including politicians, may impact Russia’s economy and Russian companies in which the Fund or an Underlying Fund invests. Actual and threatened responses to Russian military action may also impact the markets for certain Russian commodities, such as oil and natural gas, as well as other sectors of the Russian economy, and are likely to have collateral impacts on such sectors globally. Russian companies may be unable to pay dividends and, if they pay dividends, the Fund or an Underlying Fund may be unable to receive them. As a result of sanctions, the Fund is currently restricted from trading in Russian securities, including those in its portfolio, while the Underlying Index has removed Russian securities. It is unknown when, or if, sanctions may be lifted or the Fund’s ability to trade in Russian securities will resume.
Risk of Investing in Saudi Arabia. The ability of foreign investors (such as the Fundor an Underlying Fund) to invest in the
S-26


securities of Saudi Arabian issuers is relatively new. Such ability could be restricted by the Saudi Arabian government at any time, and unforeseen risks could materialize with respect to foreign ownership in such securities. The economy of Saudi Arabia is dominated by petroleum exports. A sustained decrease in petroleum prices could have a negative impact on all aspects of the economy. Investments in the securities of Saudi Arabian issuers involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of the Fund’sor Underlying Fund's investments. Such heightened risks may include, among others, expropriation and/or nationalization of assets, restrictions on and government intervention in international trade, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision making, armed conflict, crime and instability as a result of religious, ethnic and/or socioeconomic unrest. There remains the possibility that instability in the larger Middle East region could adversely impact the economy of Saudi Arabia, and there is no assurance of political stability in Saudi Arabia.
Saudi Arabia Broker Risk.  There are a number of different ways of conducting transactions in equity securities in the Saudi Arabian market.  The Fund (or an Underlying Fund) generally expects to conduct its transactions in a manner in which the Fund would not be limited by Saudi Arabian regulations to a single broker. However, there may be a limited number of brokers who can provide services to the Fund (or an Underlying Fund), which may have an adverse impact on the prices, quantity or timing of Fund (or an Underlying Fund) transactions.
Risk of Investing in the U.S. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund or the Underlying Funds has exposure.
Securities Lending Risk. The Fund  or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or the Underlying Funds may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund or the Underlying Funds 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 Fundor an Underlying Fund.
Tax Risk. Because the Fund is expected to invest in the Underlying Funds, the Fund’s realized losses on sales of shares of an Underlying Fund may be indefinitely or permanently deferred as wash sales. Distributions of short-term capital gains by an Underlying Fund will be recognized as ordinary income by the Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of an Underlying Fund, if any, would not offset net capital gains of the Fund.
Tracking Error Risk. The Fund and the Underlying Funds 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 because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences(including, as applicable, differences between a security’s price at the local market close and the Fund's or an Underlying Fund's valuation of a security at the time of calculation of the Fund's or Underlying Fund's NAV, respectively), transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual or the valuation of dividends or interest received by a Fund or distributions paid to a Fund’s or an Underlying Fund’s shareholders, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the Fund or an Underlying Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund or an Underlying Fund incurs fees and expenses, while the Underlying Index does not. The Underlying Funds are also subject to tracking error risk in seeking to track their own performance of the applicable underlying indexes.
U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of a government may cause the value of the Fund's or an Underlying Fund's U.S. Treasury obligations to decline.
Valuation Risk. The price the Fund  or an Underlying Fund could receive upon the sale of a security or other asset may differ from the Fund'sor the Underlying Fund's valuation of the security or other asset and from the value used by its underlying index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund's or an Underlying Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund's or an Underlying Fund's shares. Authorized Participants who purchase or redeem shares of the Fund or an Underlying Fund on days when the Fund or an Underlying Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

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 sale 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.

Management
Investment Adviser. BlackRock Fund Advisors.
Portfolio Managers. Jennifer Hsui, Greg Savage and Paul Whitehead (the Portfolio Managers) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Ms. Hsui, Mr. Savage and Mr. Whitehead have been Portfolio Managers of the Fund since 2012, 2008 and 2022, respectively.
Purchase and Sale of Fund Shares
The Fund is an ETF. Individual shares of the Fund may only be bought and sold in the secondary market through a broker-dealer. Because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the bid-ask spread).
Tax Information
The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing
through a tax-deferred arrangement such as a 401(k) plan or an 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.

iShares Core Aggressive Allocation ETF
Ticker: AOAStock Exchange: NYSE Arca
Investment Objective
The iShares Core Aggressive Allocation ETF (the Fund) seeks to track the investment results of an index composed of a portfolio of underlying equity and fixed income funds intended to represent an aggressive target risk allocation strategy.
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. The Fund may incur Acquired Fund Fees and Expenses. Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund's prospectus (the Prospectus). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other series of the Trust and iShares, Inc. through November 30, 2026. The contractual waiver may be terminated prior to November 30, 2026 only upon written agreement of the Trust and BFA.
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.

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:

Portfolio Turnover. The Fund and the iShares funds in which the Fund invests (each, an Underlying Fund and collectively, the Underlying Funds), may pay transaction costs, such as commissions, when they buy and sell securities (or turn over their portfolio). A higher portfolio turnover rate for the Fund or Underlying Funds may indicate higher transaction costs and may cause the Fund or Underlying Funds to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to Underlying Funds included as part of Acquired Fund Fees and Expenses), affect the Fund's performance. To the extent an Underlying Fund incurs costs from high portfolio turnover, such costs may have a
negative effect on the performance of the Fund. During the most recent fiscal year, the Fund’s portfolio turnover rate was 5% of the average value of its portfolio.
Principal Investment Strategies
The Fund is a fund of funds and seeks to achieve its investment objective by investing primarily in Underlying Funds that themselves seek investment results corresponding to their own respective underlying indexes. The Underlying Funds invest primarily in distinct asset classes, such as large- or mid-capitalization U.S. or non-U.S. equity, the aggregate bond market
S-31


(including USD-denominated bonds) or the U.S. Treasury bond market; each such asset class has its own risk profile.
The S&P Target Risk Aggressive Index (the Underlying Index) is composed of a portfolio of equity and fixed-income Underlying Funds and measures the performance of the S&P Dow Jones Indices LLC (the Index Provider or SPDJI) proprietary allocation model that is intended to represent an aggressive target risk allocation strategy as defined by SPDJI. The Underlying Index seeks to emphasize exposure to equities, maximizing opportunities for long-term capital accumulation. The Underlying Index may include small allocations in fixed income to enhance portfolio efficiency. SPDJI’s estimation of an aggressive target risk allocation may differ from your own.
The Fund is designed for investors seeking long-term capital appreciation. As of July 31, 2023, the Underlying Index included a fixed allocation of 80% of its assets in Underlying Funds that invest primarily in equity securities and 20% of its assets in Underlying Funds that invest primarily in bonds. As of July 31, 2023, the Fund invested approximately 81.17% of its assets in Underlying Funds that invest primarily in equity securities, 18.69% of its assets in Underlying Funds that invest primarily in bonds and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.
As of July 31, 2023, the Fund invested in the iShares Core International Aggregate Bond ETF, iShares Core MSCI Emerging Markets ETF, iShares Core MSCI International Developed Markets ETF, iShares Core S&P 500 ETF, iShares Core S&P Mid-Cap ETF, iShares Core S&P Small-Cap ETF, iShares Core Total USD Bond Market ETF and money market funds advised by BFA or its affiliates (BlackRock Cash Funds). BFA may add, eliminate or replace any or all Underlying Funds at any time. As of July 31, 2023, a significant portion of the Underlying Index is represented by companies in the financials and technology 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. Unlike many investment companies, 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 Fundand an Underlying Fund may or may not hold all of the securities in the applicable Underlying Index.
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).
The Underlying Index is a product of SPDJI, which isindependent 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(either directly or through its investments in the Underlying Funds), 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.
Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Certain Underlying Funds invest in common stocks, which generally subjecttheir holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.
S-32


Allocation Risk. The Fund’s ability to achieve its investment objective depends upon the Index Provider's ability to develop a model that accurately assesses the Fund’s asset class allocation and selects the best mix of Underlying Funds and other ETFs. There is a risk that the Index Provider's evaluations and assumptions regarding asset classes or Underlying Funds, which are utilized as inputs in the model, may be incorrect in view of actual market conditions.
Investment in Underlying Funds Risk. The Fund invests substantially all of its assets inthe Underlying Funds, so the Fund’s investment performance is directly related to the performance of the Underlying Funds. The Fund’s NAV will change with changes in the value of the Underlying Funds and other securities in which the Fund invests based on their market valuations. An investment in the Fund will entail more costs and expenses than a direct investment in the Underlying Funds.
As the Underlying Funds, or the Fund’s allocations among the Underlying Funds, change from time to time, or to the extent that the total annual fund operating expenses of any Underlying Fund change, the weighted average operating expenses borne by the Fund may increase or decrease.
Market Risk. The Fundand the Underlying Funds 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, 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, the Underlying Funds and their investments and could result in increased premiums or discounts to the Fund’sor Underlying Fund's NAV.
Index-Related Risk. 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 disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time 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.
Affiliated Fund Risk. In managing the Fund, BFA has the ability to select Underlying Funds and substitute Underlying Funds with other exchange-traded funds (ETFs) that it believes will achieve the Fund’s objective. BFA may be subject to potential conflicts of interest in selecting Underlying Funds and substituting Underlying Funds with other ETFs because the fees paid to BFA by some Underlying Funds and other ETFs managed by BFA may be higher
than the fees paid by other Underlying Funds. If an Underlying Fund or other ETF holds interests in an affiliated fund in excess of a certain amount, the Fund may be prohibited from purchasing shares of that Underlying Fund or other ETF.
Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's or an Underlying Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.
Authorized Participant Concentration Risk.  Only an Authorized Participant (as defined in the Creations and Redemptions section of this prospectus (the Prospectus)) may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund shares may be 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 ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.
Calculation Methodology Risk. The Index Provider relies 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 calculation methodology or sources of information will provide an accurate assessment of included components.
Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund or an Underlying Fund may call or repay the security before its stated maturity, and the Fund or an Underlying Fund may have to reinvest the proceeds in securities with lower yields, which would result in a decline in the Fund's income, or in securities with greater risks or with other less favorable features.
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 or an Underlying Fund's investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.
Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s or an Underlying Fund's investment in that issuer. The degree of
S-33


credit risk depends on an issuer's or counterparty's financial condition and on the terms of an obligation.
Currency Risk. Because the Fund's and the Underlying Funds' NAVs are determined in U.S. dollars, the Fund's NAV could decline if a currency of a non-U.S. market in which a Fund or an Underlying Fund invests depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund's NAV may change quickly and without warning.
Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund or the Underlying Funds, the Funds' or the Underlying Funds' adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.
Derivatives Risk. The Fund  or an Underlying Fund may invest in certain types of derivatives contracts, including futures, options and swaps, which can be more sensitive to changes in interest rates or to sudden fluctuations in market prices than conventional securities, which can result in greater losses to the Fund.
Extension Risk. During periods of rising interest rates, certain debt obligations may be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in the Fund’s income and potentially in the value of the Fund’s or an Underlying Fund's investments.
Financials Sector Risk. The performance of companies in the financials sector may be adversely impacted by many factors, including, among others, changes in government regulations, economic conditions, and interest rates, credit rating downgrades, adverse public perception, exposure concentration and decreased liquidity in credit markets. The impact of changes in regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. Cybersecurity incidents and technology malfunctions and failures have become increasingly frequent and have caused significant losses to companies in this sector, which may negatively impactan Underlying Fund.
Geographic Risk. A natural disaster could occur in a geographic region in which the Fund or an Underlying Fund invests, which could adversely affect the economy or the business operations of companies in the specific geographic region, causing an adverse impact on the Fund's or an Underlying Fund's investments in, or which are exposed to, the affected region.
High Yield Securities Risk. Securities that are rated below investment-grade (commonly referred to as junk bonds, which may include those bonds rated below BBB- by Standard & Poor's® Global Ratings, a subsidiary of S&P Global (S&P Global Ratings) and Fitch Ratings, Inc. (Fitch) or below Baa3 by Moody's Investors Service, Inc. (Moody's)), or are unrated, may be deemed speculative, may involve greater levels of risk than higher-rated securities of similar maturity and may be more likely to default.
Income Risk. The Fund's income may decline if interest rates fall. This decline in income can occur because the Fund or an Underlying Fund may subsequently invest in lower-yielding bonds when bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the Fund or an Underlying Fund otherwise needs to purchase additional bonds.
Indexing Investment Risk. The Fundand the Underlying Funds are not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.
Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund's NAV. Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.
Interest Rate Risk. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by the Fund or an Underlying Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by the Fund or an Underlying Fund. Because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt
S-34


securities. The historically low interest rate environment in recent years heightens the risks associated with rising interest rates.
Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund or an Underlying Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.
Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.
Management Risk. As the Fund or the Underlying Funds will not fully replicate their respective indexes, they are subject to the risk that BFA's investment strategy may not produce the intended results.
Market Trading Risk. The Fund and the Underlying Funds face numerous market trading risks, including the potential lack of an active market for their shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.
Mid-Capitalization Companies Risk. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments. In addition, the securities of mid-capitalization companies may be more volatile and less liquid than those of large-capitalization companies.
Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index's allocation model will achieve its intended results or maximize returns or minimize risk, or be appropriate for every investor seeking a particular risk profile.
National Closed Market Trading Risk. To the extent that the underlying securities or other instruments held by the Fund or the Underlying Funds trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s or an Underlying Fund's shares trade is open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., the Fund’s or an Underlying Fund's quote from the closed foreign market).The impact of a closed foreign market on the Fund or an Underlying Fund is likely to be greater where a large portion of the Fund’s or an Underlying Fund's underlying securities or other instruments trade on that closed foreign market or when the foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s or an Underlying Fund's NAV that may be greater than those experienced by other ETFs.
Non-U.S. Issuers Risk. Securities issued by non-U.S. issuers carry different risks from securities issued by U.S. issuers. These risks include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability, regulatory and economic differences, and potential restrictions on the flow of international capital.
Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund or an Underlying Fund may lose money due to political, economic and geographic events affecting issuers of non-U.S. securities or non-U.S. markets. In addition, non-U.S. securities markets 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.
Operational Risk. The Fundand the Underlying Funds are exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third parties, failed or inadequate processes and technology or systems failures. The Fund, the Underlying Funds and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.
Prepayment Risk. During periods of falling interest rates, issuers of certain debt obligations may repay principal prior to the security’s maturity, which may cause the Fund to have to reinvest in securities with lower yields or higher risk of default, resulting in a decline in the Fund’s income or return potential.
Reinvestment Risk. The Fund  or an Underlying Fund may invest a portion of its assets in short-term fixed-income instruments and, as a result, may be adversely affected if interest rates fall because they may have to invest in lower-yielding bondsas bonds mature.
Reliance on Trading Partners Risk. The Fund and certain Underlying Funds invest in countries or regions whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund's investments. Through its holdings of securities of certain issuers, the Fund is specifically exposed to Asian Economic Risk, European Economic Risk and U.S. Economic Risk.
Risk of Investing in China. Investments in Chinese securities, including certain Hong Kong-listed and U.S.-listed securities, subject the Fund or the Underlying Funds to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of
S-35


economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability.
Chinese companies are also subject to the risk that Chinese authorities can intervene in their operations and structure. Internal social unrest or confrontations with neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of 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, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which the Fund invests. Incidents involving China's or the region's security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund's investments. Export growth continues to be a major driver of China's rapid economic growth. Reduction in spending on Chinese products and services, supply chain diversification, 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 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, 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 Fund is not actively managed and does not select investments based on investor protection considerations.
Risk of Investing in Developed Countries. The Fund’s and the Underlying Fund's investment in developed country issuers may subject the Fund to legal, regulatory, political, currency, security, economic and other risks associated with developed countries. Developed countries tend to represent a significant portion of the global economy and have generally experienced slower economic growth than some less developed countries. Certain developed countries have experienced security concerns, such as war, terrorism and strained international relations. Incidents involving a country’s or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s or an Underlying Fund's investments. In addition, developed countries may be adversely impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.
Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory, currency and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’sor an Underlying Fund's ownership rights in its portfolio securities as a result of the system of share registration and custody in Russia. Governments in the U.S. and many other countries have imposed economic sanctions on certain Russian individuals and Russian corporate and banking entities. A number of jurisdictions may also institute broader sanctions on Russia. Russia has issued a number of countersanctions, some of which restrict the distribution of profits by limited liability companies (e.g., dividends), and prohibit Russian persons from entering into transactions with designated persons from unfriendly states as well as the export of raw materials or other products from Russia to certain sanctioned persons. Russia launched a large-scale invasion of Ukraine on February 24, 2022. The extent and duration of the military action, resulting sanctions and resulting future market disruptions, including declines in its stock markets and the value of the ruble against the U.S. dollar, are impossible to predict, but could be significant. Disruptions caused by Russian military action or other actions (including cyberattacks and espionage) or resulting actual and threatened responses to such activity, including purchasing and financing restrictions, boycotts or changes in consumer or purchaser preferences, sanctions, import and export restrictions, tariffs or cyberattacks on the Russian government, Russian companies, or Russian individuals, including politicians, may impact Russia’s economy and Russian companies in which the Fund or an Underlying Fund invests. Actual and threatened responses to Russian military action may also impact the markets for certain Russian commodities, such as oil and natural gas, as well as other sectors of the Russian economy, and are likely to have collateral impacts on such sectors globally. Russian companies may be unable to pay dividends and, if they pay dividends, the Fund or an Underlying Fund may be unable to receive them. As a result of sanctions, the Fund is currently restricted from trading in Russian securities, including those in its portfolio, while the Underlying Index has removed Russian securities. It is unknown when, or if, sanctions may be lifted or the Fund’s ability to trade in Russian securities will resume.
Risk of Investing in Saudi Arabia. The ability of foreign investors (such as the Fundor an Underlying Fund) to invest in the
S-36


securities of Saudi Arabian issuers is relatively new. Such ability could be restricted by the Saudi Arabian government at any time, and unforeseen risks could materialize with respect to foreign ownership in such securities. The economy of Saudi Arabia is dominated by petroleum exports. A sustained decrease in petroleum prices could have a negative impact on all aspects of the economy. Investments in the securities of Saudi Arabian issuers involve risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of the Fund’sor Underlying Fund's investments. Such heightened risks may include, among others, expropriation and/or nationalization of assets, restrictions on and government intervention in international trade, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision making, armed conflict, crime and instability as a result of religious, ethnic and/or socioeconomic unrest. There remains the possibility that instability in the larger Middle East region could adversely impact the economy of Saudi Arabia, and there is no assurance of political stability in Saudi Arabia.
Saudi Arabia Broker Risk.  There are a number of different ways of conducting transactions in equity securities in the Saudi Arabian market.  The Fund (or an Underlying Fund) generally expects to conduct its transactions in a manner in which the Fund would not be limited by Saudi Arabian regulations to a single broker. However, there may be a limited number of brokers who can provide services to the Fund (or an Underlying Fund), which may have an adverse impact on the prices, quantity or timing of Fund (or an Underlying Fund) transactions.
Risk of Investing in the U.S. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund or the Underlying Funds has exposure.
Securities Lending Risk. The Fund  or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or the Underlying Funds may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund or the Underlying Funds 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 Fundor an Underlying Fund.
Tax Risk. Because the Fund is expected to invest in the Underlying Funds, the Fund’s realized losses on sales of shares of an Underlying Fund may be indefinitely or permanently deferred as wash sales. Distributions of short-term capital gains by an Underlying Fund will be recognized as ordinary income by the Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of an Underlying Fund, if any, would not offset net capital gains of the Fund.
Technology Sector Risk. Technology companies, including information technology companies,may have limited product lines, markets, financial resources or personnel. Technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights. Companies in the technology sector may face increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.
Tracking Error Risk. The Fund and the Underlying Funds 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 because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences(including, as applicable, differences between a security’s price at the local market close and the Fund's or an Underlying Fund's valuation of a security at the time of calculation of the Fund's or Underlying Fund's NAV, respectively), transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual or the valuation of dividends or interest received by a Fund or distributions paid to a Fund’s or an Underlying Fund’s shareholders, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the Fund or an Underlying Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund or an Underlying Fund incurs fees and expenses, while the Underlying Index does not. The Underlying Funds are also subject to tracking error risk in seeking to track their own performance of the applicable underlying indexes.
Valuation Risk. The price the Fund  or an Underlying Fund could receive upon the sale of a security or other asset may differ from the Fund'sor the Underlying Fund's valuation of the security or other asset and from the value used by its underlying index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund's or an Underlying Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund's or an Underlying Fund's shares. Authorized Participants who purchase or redeem shares of the Fund or an Underlying Fund on days when the Fund or an Underlying Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Performance Information
The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide some indication of the risks of investing in the Fund by showing how the Fund’s average annual returns for 1, 5, and 10 years compare with the Underlying Index. Both assume that all dividends and distributions have been reinvested in the Fund. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. If BFA had not waived certain Fund fees during certain periods, the Fund's returns would have been lower.

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 sale 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.

Management
Investment Adviser. BlackRock Fund Advisors.
Portfolio Managers. Jennifer Hsui, Greg Savage and Paul Whitehead (the Portfolio Managers) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Ms. Hsui, Mr. Savage and Mr. Whitehead have been Portfolio Managers of the Fund since 2012, 2008 and 2022, respectively.
Purchase and Sale of Fund Shares
The Fund is an ETF. Individual shares of the Fund may only be bought and sold in the secondary market through a broker-dealer. Because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the bid-ask spread).
Tax Information
The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing
through a tax-deferred arrangement such as a 401(k) plan or an 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.

More Information About the Funds
This Prospectus contains important information about investing in the Funds. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Funds is available at www.iShares.com.
BFA is the investment adviser to the Funds. Shares of each Fund are listed for trading on NYSE Arca, Inc. (NYSE Arca). The market price for a share of a Fund may be different from the Fund’s most recent NAV. Each Fund has its own CUSIP number and exchange trading symbol.
ETFs are funds that trade like other publicly traded securities and are designed to track an index. Similar to shares of an index mutual fund, each share of a Fund represents an ownership interest in an underlying portfolio of securities and other instruments intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Funds may be purchased or redeemed directly from the Funds at NAV solely by Authorized Participants and only in aggregations of a specified number of shares (Creation Units). Also unlike shares of a mutual fund, 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.
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 each Fund and its Underlying Index may vary for a number of reasons, including transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between each Fund’s portfolio and its Underlying Index resulting from the Funds' use of representative sampling or from legal restrictions (such as diversification requirements) that apply to each Fund but not to its Underlying Index. From time to time, the Index Provider may make changes to the methodology or other adjustments to a Fund's Underlying Index. Unless otherwise determined by BFA, any such change or adjustment will be reflected in the calculation of a Fund's Underlying Index performance on a going-forward basis after the effective date of such change or adjustment. Therefore, a Fund's Underlying Index performance shown for periods prior to the effective date of any such change or adjustment will generally not be recalculated or restated to reflect such change or adjustment.
Tracking error is the divergence of the performance (return) of each Fund's portfolio from that of its Underlying Index. Because each Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it 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.
An investment in a Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.
Each Fund's investment objective and its Underlying Index may be changed without shareholder approval.
Investment Objectives of the Funds
Each Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of an S&P Target Risk Index (each, an Underlying Index and collectively, the Underlying Indexes). Each Underlying Index is comprised entirely of securities of iShares funds (each, an Underlying Fund and collectively, the Underlying Funds) that themselves seek investment results that correspond generally to the price and yield performance, before fees and expenses, of their own respective underlying indexes. Each Fund is an ETF fund of funds and seeks its investment objective by investing primarily in Underlying Funds that are iShares funds.

A Further Discussion of Principal Risks
Each Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. Each Fund may be exposed to these risks directly or indirectly through the Fund's investments in the Underlying Funds. You could lose all or part of your investment in the Funds, and the Funds could underperform other investments. The order of the below risk factors does not indicate the significance of any particular risk factor. Each Fund discloses its portfolio holdings daily at www.iShares.com.
Affiliated Fund Risk. In managing the Funds, BFA has the ability to select Underlying Funds and substitute Underlying Funds with other ETFs that it believes will achieve each Fund’s objective. BFA may be subject to potential conflicts of interest in selecting Underlying Funds and substituting Underlying Funds with other ETFs because the fees paid to BFA by some Underlying Funds and other ETFs managed by BFA may be higher than the fees paid by other Underlying Funds. If an Underlying Fund or other ETF holds interests in an affiliated fund, the Funds may be prohibited from purchasing shares of that Underlying Fund or other ETF.
Allocation Risk. Each Fund’s ability to achieve its investment objective depends upon the Index Provider’s ability to develop a model that accurately assesses each Fund’s asset class allocation and selects the best mix of Underlying Funds and other ETFs. There is a risk that the Index Provider’s evaluations and assumptions regarding asset classes or Underlying Funds, which are utilized as inputs in the model, may be incorrect in view of actual market conditions. Each Fund’s Underlying Index may overweight certain asset classes relative to market capitalization-weighted benchmarks. Each Fund will underperform such benchmarks when asset classes that are overweighted in each Fund’s Underlying Index underperform other asset classes.
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, however, 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. Any 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 or an Underlying Fund invests. In particular, China is a key trading partner of many Asian countries and any changes in trading relationships between China and other Asian countries may affect the region as a whole. Many Asian countries are subject to political risk, including political instability, corruption and regional conflict with neighboring countries. North Korea and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Escalated tensions involving the two countries and any outbreak of hostilities between the two countries, or even the threat of an outbreak of hostilities, could have a severe adverse effect on the entire Asian region. Certain Asian countries have developed increasingly strained relationships with the U.S. or with China, and if these relations were to worsen, they could adversely affect Asian issuers that rely on the U.S. or China for trade. 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'sor an Underlying Fund's investments.
Asset Class Risk. The securitiesand other assets in the Underlying Indexes or in a Fund’s or an Underlying Fund's portfolio may underperform in comparison to other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, market segments, asset classes or sectors. Various types of securities, currencies and indexes may experience cycles of outperformance and underperformance in comparison to the general financial markets depending upon 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.
Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with a Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. Each Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to a Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be 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 because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.
Calculation Methodology Risk. The Index Provideres 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 Funds nor BFA can offer assurances that the Indexes' calculation methodology or sources of information will provide an accurate assessment of included components.
2


Call Risk. During periods of falling interest rates, an issuer of a callable bond held by a Fund and an Underlying Fund may call or repay the security before its stated maturity, and a Fund and an Underlying Fund may have to reinvest the proceeds in securities with lower yields, which would result in a decline in a Fund’s income, or in securities with greater risks or with other less favorable features.
Concentration Risk. Each 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 a Fund's or an Underlying Fund's investments are concentrated in the securities and/or other assets a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, project types, group of project types, sector, market segment or asset class. Each Fund may be more adversely affected by the underperformance of those securities and/or other assets, may experience increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities and/or other assets than a fund that does not concentrate its investments.
Credit Risk. Credit risk is the risk that the issuer or guarantor of a debt instrument or the counterparty to a derivatives contract, repurchase agreement or loan of portfolio securities will be unable or unwilling to make its timely interest and/or principal payments when due or otherwise honor its obligations. There are varying degrees of credit risk, depending on an issuer’s or counterparty’s financial condition and on the terms of an obligation, which may be reflected in the issuer’s or counterparty’s credit rating. There is the chance that a Fund’s or an Underlying Fund's portfolio holdings will have their credit ratings downgraded or will default (i.e., fail to make scheduled interest or principal payments), or that the market’s perception of an issuer’s creditworthiness may worsen, potentially reducing such Fund’s or an Underlying Fund's income level or share price, which may adversely affect the value of each Fund or an Underlying Fund.
Currency Risk. Because the Funds' and the Underlying Funds' NAVs are determined on the basis of the U.S. dollar, investors may lose money if a currency of a non-U.S. market in which a Fund or an Underlying Fund invests depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency, even if such 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.
Cybersecurity Risk. Each Fund,Authorized Participants, service providers and the relevant listing exchange are susceptible to operational, information security and related cyber risks both directly and through their service providers.  Similar types of cybersecurity risks are also present for issuers of securities in which each Fund or the Underlying Funds invest, which could result in material adverse consequences for such issuers and may cause a Fund’s or an Underlying Fund's investment in such issuers to lose value. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber incidents include, but are not limited to, gaining unauthorized access to digital systems (e.g., through hacking or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyberattacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Geopolitical tensions may increase the scale and sophistication of deliberate attacks, particularly those from nation-states or from entities with nation-state backing.
Cybersecurity failures by, or breaches of, the systems of the Funds' or an Underlying Fund's adviser, distributor and other service providers (including, but not limited to, index and benchmark providers, fund accountants, custodians, transfer agents and administrators), market makers, Authorized Participants or the issuers of securities in which each Fund or the Underlying Funds invest have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses, interference with a Fund’s or an Underlying Fund's ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of each Fund or each Underlying Fund or their service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyberattacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of each Fund or Underlying Fund inaccessible, inaccurate or incomplete. Substantial costs may be incurred by each Fund or Underlying Fund in order to resolve or prevent cyber incidents. While each Fund and the Underlying Funds have established business continuity plans in the event of, and risk management systems to prevent, such cyber incidents, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified, that prevention and remediation efforts will not be successful or that cyberattacks will go undetected. Furthermore, each Fund cannot control the cybersecurity plans and systems put in place by service providers to each Fund, issuers in which each Fund invests, the Index Provider, market makers or Authorized Participants. Each Fund and its shareholders could be negatively impacted as a result.
Derivatives Risk. A derivative is a financial contract, the value of which depends on or is derived from, the value of an underlying asset such as a security or an index. Each Fundand Underlying Fund may invest in certain types of derivatives contracts, including futures, options and swaps. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus a Fund’s or an Underlying Fund's losses may be greater if it invests in derivatives than if it invests only in conventional securities.

Equity Securities Risk. Certain Underlying Funds invest in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes. Certain Underlying Funds invest in common stocks, which generally subjecttheir holders to more risks than preferred stocks and debt securities because common stockholders' claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.
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 United Kingdom's (the U.K.) economy may be affected by global economic, industrial and financial shifts. Changes in imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro (the common currency of eurozone countries), the default or threat of default by an EU member state on its sovereign debt and/or an economic recession in an EU member state may have a significant adverse effect on the economies of other EU member states and their trading partners. The European financial markets have historically experienced volatility and adverse trends due to concerns about economic downturns or government debt levels in several European countries, including, but not limited to, Austria, Belgium, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. These events have affected and may in the future adversely affect the exchange rate of the euro and may significantly affect European countries.
Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. The U.K. left the EU (Brexit) on January 31, 2020. Brexit could adversely affect European or worldwide political, regulatory, economic or market conditions and could contribute to instability in global political institutions, regulatory agencies and financial markets.
The national politics of countries in Europe have been unpredictable and subject to influence by disruptive political groups and ideologies, including, for example, secessionist movements. The governments of European countries may be subject to change and such countries may experience social and political unrest. Unanticipated or sudden political or social developments may result in sudden and significant investment losses. The occurrence of terrorist incidents throughout Europe or war in the region could also impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of a Fund's investments.
Russian Invasion of Ukraine. Russia launched a large-scale invasion of Ukraine on February 24, 2022. The extent and duration of the military action, resulting sanctions and resulting future market disruptions, including declines in its stock markets and the value of the ruble against the U.S. dollar, are impossible to predict, but could be significant. Disruptions caused by Russian military action or other actions (including cyberattacks and espionage) or resulting actual and threatened responses to such activity, including purchasing and financing restrictions, boycotts or changes in consumer or purchaser preferences, sanctions, import and export restrictions, tariffs or cyberattacks on the Russian government, Russian companies or Russian individuals, including politicians, may impact Russia's economy, Russian issuers of securities in which a Fund invests, or the economies of Europe as a whole. Actual and threatened responses to Russian military action may also impact the markets for certain Russian commodities, such as oil and natural gas, as well as other sectors of the Russian economy, and are likely to have collateral impacts on such sectors across Europe and globally.
Extension Risk. During periods of rising interest rates, certain debt obligations may be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in a Fund’s or an Underlying Fund's income and potentially in the value of a Fund’s or an Underlying Fund's investments.
Financials Sector Risk. Companies in the financials sector are subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge, the amount of capital and liquid assets they must maintain and, potentially, their size. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. Increased risk taking by financial companies may also result in greater overall risk in the U.S. and global financials sector. The impact of changes in capital requirements, or recent or future regulation in various countries, on any individual financial company or on the financials sector as a whole cannot be predicted.
Certain risks may impact the value of investments in the financials sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financials sector are exposed directly to the credit risk of their borrowers and counterparties, who may be leveraged to an unknown degree, including through swaps and other derivatives products. Financial services companies may have significant exposure to the same borrowers and counterparties, with the result that a borrower’s or counterparty’s inability to meet its obligations to one company may affect other
4


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 financials sector generally. Companies in the financials sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades, adverse public perception and adverse conditions in other related markets. Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. The financials sector is particularly sensitive to fluctuations in interest rates. The financials sector is also a target for cyberattacks. Cybersecurity incidents and technology malfunctions and failures have become increasingly frequent and have caused significant losses to companies in this sector, which may negatively impact a Fund. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law.
Geographic Risk. Some of the companies in which the Underlying Funds invest are located in parts of the world that have historically been prone to natural disasters such as earthquakes, tornadoes, volcanic eruptions, droughts, floods, hurricanes or tsunamis and are economically sensitive to environmental events. Any such event may adversely impact the economies of these geographic areas or business operations of companies in these geographic areas, causing an adverse impact on the value of a Fund.
High Yield Securities Risk. Securities that are rated below investment-grade (commonly referred to as junk bonds, which may include those bonds rated below BBB- by S&P Global Ratings and Fitch, or below Baa3 by Moody’s), or are unrated, may be deemed speculative, may involve greater levels of risk than higher-rated securities of similar maturity and may be more likely to default.
The major risks of high yield securities investments include:
High yield securities may be issued by less creditworthy issuers. Issuers of high yield securities may have a larger amount of outstanding debt relative to their assets than issuers of investment-grade bonds. In the event of an issuer’s bankruptcy, claims of other creditors may have priority over the claims of high yield securities holders, leaving few or no assets available to repay high yield securities holders.
Prices of high yield securities are subject to extreme price fluctuations. Adverse changes in an issuer’s industry and general economic conditions may have a greater impact on the prices of high yield securities than on other higher rated fixed-income securities. The credit rating of a high yield security does not necessarily address its market value risk. Ratings and market value may change from time to time, positively or negatively, to reflect new developments regarding the issuer.
Issuers of high yield securities may be unable to meet their interest or principal payment obligations because of an economic downturn, specific issuer developments, or the unavailability of additional financing.
High yield securities frequently have redemption features that permit an issuer to repurchase the security from a Fund or an Underlying Fund before it matures. If the issuer redeems high yield securities held by a Fund or the Underlying Fund, a Fund or an Underlying Fund may have to invest the proceeds in bonds with lower yields and may lose income.
High yield securities may be less liquid than higher rated fixed-income securities, even under normal economic conditions. There are fewer dealers in the high yield securities market, and there may be significant differences in the prices quoted for high yield securities by the dealers. Because high yield securities may be less liquid than higher rated fixed-income securities, judgment may play a greater role in valuing certain of a Fund'sor an Underlying Fund's securities than is the case with securities trading in a more liquid market.
A Fundor an Underlying Fund may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a defaulting issuer.
Income Risk. A Fund’s income may decline when interest rates fall.  This decline can occur because a Fund or an Underlying Fund may subsequently invest in lower-yielding bonds as bonds in a Fund's portfolio mature or are called, bonds in the Underlying Index are substituted, or a Fund or an Underlying 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.
Indexing Investment Risk. The Fundsand the Underlying Funds are not actively managed and may be affected by a general decline in market segments related to their Underlying Indexes. Each Fund and each Underlying Fund invest in securities included in, or representative of, their respective underlying index, regardless of their investment merits. BFA generally does not attempt to invest the Funds' or the Underlying Funds' assets in defensive positions under any market conditions, including declining markets.
Index-Related Risk. The Funds seek to achieve a return that corresponds generally to the price and yield performance, before fees and expenses, of the Underlying Indexes, as published by their respective index providers. There is no assurance that the index providers or any agents that act on their behalf will compile the Underlying Indexes accurately, or that the Underlying Indexes will be determined, composed or calculated accurately. While the index providers do provide descriptions of what the Underlying Indexes are designed to achieve, neither the index providers nor their agents provide any warranty or accept any liability in relation to the quality, accuracy or completeness of the Underlying Indexes or their related data, and they do not guarantee that the Underlying Indexes will be in line with the index providers’ described index methodology. BFA’s mandate as described in this Prospectus is to manage the Funds consistently with the Underlying Indexes provided by the index providers to BFA. BFA does not provide any warranty or guarantee against the index providers’ or agents’
5


errors. Errors in respect of the quality, accuracy and completeness of the data used to compile the Underlying Indexes may occur from time to time and may not be identified by the index providers and corrected for a period of time or at all, particularly where the indexes are less commonly used as benchmarks. Therefore, gains, losses or costs associated with index provider errors will generally be borne by the Funds and their shareholders. For example, during a period where a Fund’s Underlying Index contains incorrect constituents, the Funds tracking such published Underlying Index would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. As such, errors may result in a negative or positive performance impact to the Funds and their shareholders. Shareholders should understand that any gains from index provider errors will be kept by the Funds and their shareholders and any losses resulting from index provider errors will be borne by the Funds and their 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 to the Underlying Indexes. This could cause the Underlying Indexes to vary from its normal or expected composition. The postponement of a scheduled rebalance could mean that constituents of the Underlying Indexes that would otherwise be removed at rebalance due to changes in market capitalizations, issuer credit ratings, or other reasons may remain, causing the performance and constituents of the Underlying Indexes to vary from those expected under normal conditions. Apart from scheduled rebalances, the index providers may carry out additional ad hoc rebalances to the Underlying Indexes due to reaching certain weighting constraints, unusual market conditions or corporate events or, for example, to correct an error in the selection of index constituents. Where the Underlying Index of a Fund is rebalanced and the Fund in turn rebalances its portfolio to attempt to correlate it to its Underlying Index, any transaction costs and market exposure arising from such portfolio rebalancing will be borne directly by the Funds and their shareholders. Unscheduled rebalances to the Underlying Indexes may also expose the Funds to tracking error risk, which is the risk that its returns may not track exactly those of the Underlying Indexes. Therefore, errors and additional ad hoc rebalances carried out by the index providers to the Underlying Indexes may increase the costs and market exposure risk of the Funds.
Similar risks exist for the Underlying Funds in tracking their benchmarks, which may result in the Funds' performance deviating from the return of the Underlying Index.
Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may adversely affect the economies of many nations and the global economy and may impact individual issuers and capital markets in ways that cannot be foreseen.
An infectious illness outbreak may result in travel restrictions, closed international borders, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, lower consumer demand, temporary and permanent closures of businesses, layoffs, defaults and other significant economic, social and political impacts, as well as general concern and uncertainty.
An infectious illness outbreak may result in extreme volatility, severe losses, credit deterioration of issuers, and disruptions in markets, which could adversely impact a Fund and its investments, including impairing any hedging activity.
Certain local markets may be subject to closures. Any suspension of trading in markets in which the Funds or an Underlying Fund invests will have an impact on the Fundsor an Underlying Fund and their investments and will impact the Fund’sor an Underlying Fund's ability to purchase or sell securities in such markets.Market or economic disruptions could result in elevated tracking error and increased premiums or discounts to the Fund's NAV. Additionally, an outbreak could impair the operations of the Fund’s service providers, including BFA, which could adversely impact the Fund.
Governmental and quasi-governmental authorities and regulators throughout the world may respond to an outbreak and any resulting economic disruptions with a variety of fiscal and monetary policy changes, including direct capital infusions into companies and other issuers, new monetary policy tools, and changes in interest rates. A reversal of these policies, or the ineffectiveness of such policies, is likely to increase market volatility, which could adversely affect a Fund’sor an Underlying Fund's investments.
An outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally, which could adversely affect a Fund and its investments and could result in increased premiums or discounts to the Funds' NAV.
Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.
Interest Rate Risk. If interest rates rise, the value of fixed-income securities or other instruments held by the Funds or an Underlying Fund would likely decrease. A measure investors commonly use to determine this price sensitivity is called duration. Fixed-income securities with longer durations tend to be more sensitive to interest rate changes, usually making their prices more volatile than those of securities with shorter durations. 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 if the bond had a one year duration. To the extent the Funds or an Underlying Fund invests a substantial portion of its assets in fixed-income securities with longer duration, rising interest rates may cause the value of the Funds' or an Underlying Fund's investments to decline significantly, which may adversely affect the value of each Fund or an Underlying Fund. An increase in interest rates may lead to heightened volatility in the fixed-income markets and adversely affect certain fixed-income investments, including those held by
6


the Funds or an Underlying Fund. Because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities. In addition, decreases in fixed-income dealer market-making capacity may lead to lower trading volume, heightened volatility, wider bid-ask spreads and less transparent pricing in certain fixed-income markets.
The historically low interest rate environment in recent years was created in part by the world’s major central banks keeping their overnight policy interest rates at, near or below zero percent and implementing monetary policy facilities, such as asset purchase programs, to anchor longer-term interest rates below historical levels. During periods of very low or negative interest rates, a Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Certain countries have recently experienced negative interest rates on certain fixed-income instruments. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from a Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are set at low levels and the market prices of portfolio securities have increased, the Funds or an Underlying Fund may have a very low or even negative yield. A low or negative yield would cause the Funds or an Underlying Fund to lose money in certain conditions and over certain time periods. Central banks may increase their short-term policy rates or begin phasing out, or tapering, accommodative monetary policy facilities in the future. The timing, coordination, magnitude and effect of such policy changes on various markets are uncertain, and such changes in monetary policy may adversely affect the value of a Fund’s investments.
Investment in Underlying Funds Risk. Each Fund invests substantially all of its assets inthe Underlying Funds, so each Fund’s investment performance is directly related to the performance of the Underlying Funds. Each Fund may also invest in other funds, including money market funds. Each Fund’s NAV will change with changes in the value of the Underlying Funds and other securities in which each Fund invests based on their market valuations. An investment in a Fund will entail more direct and indirect costs and expenses than a direct investment in the Underlying Funds. For example, in addition to the expenses of a Fund, a Fund indirectly pays a portion of the expenses (including operating expenses and management fees) incurred by the Underlying Funds, although some of such fees will be offset by the fee waiver by BFA.
One Underlying Fund may buy the same securities that another Underlying Fund sells. Also, an investor in a Fund may receive taxable gains from portfolio transactions by the Underlying Funds, as well as taxable gains from transactions in shares of the Underlying Funds held by the Fund.
As the Underlying Funds, or a Fund's allocations among the Underlying Funds, change from time to time, or to the extent that the total annual fund operating expenses of the Underlying Funds change, the weighted average operating expenses borne by a Fund may increase or decrease.
Issuer Risk. The performance of a Fund depends on the performance of individual securities to which a Fund or an Underlying Fund has exposure. A Fund may be adversely affected if an issuer of underlying securities held by the Fund or an Underlying Fund is unable or unwilling to repay principal or interest when due. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures, credit deterioration of the issuer or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline. An issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations. 
Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.
Management Risk. Because BFA uses a representative sampling indexing strategy, each Fund will not fully replicate its Underlying Index and may hold securities not included in its Underlying Index. As a result, a Fund is subject to the risk that BFA’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.
Market Risk. Each Fundand the Underlying Funds 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, regions, markets, industries, sectors or asset classes, as applicable. Local, regional or global events such as war, acts of terrorism, 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 Funds, the Underlying Funds and their investments and could
7


result in increased premiums or discounts to a Fund’sor Underlying 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.
Absence of Active Market. Although shares of the Funds and the Underlying Funds are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained by market makers or Authorized Participants.
Risk of Secondary Listings. The Funds' shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Funds' primary listing is maintained, and may otherwise be made 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 listing or trading on any exchange or in any market. The Funds' 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 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 Fundor an Underlying Fund may trade in the secondary market at times when the Fund or the Underlying Funds do not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Funds or the Underlying Funds accept purchase and redemption orders. If a Fund purchases shares of an Underlying Fund at a time when the market price of Underlying Fund shares is at a premium to their NAV or sells Underlying Fund shares when their market price is at a discount to their NAV, the Fund may incur losses.
Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or for other reasons. In addition, trading in Fund shares on a stock excha
