The Markets in Review

Dear Shareholder,

The 12-month reporting period as of February 28, 2022 saw a continuation of the resurgent growth that followed the initial coronavirus (or “COVID-19”) pandemic reopening, albeit at a slower pace. The global economy weathered the emergence of several variant strains and the resulting peaks and troughs in infections amid optimism that increasing vaccinations and economic adaptation could help contain the pandemic’s disruptions. However, rapid changes in consumer spending led to supply constraints and elevated inflation. Moreover, while the foremost effect of Russia’s invasion of Ukraine has been a severe humanitarian crisis, the invasion has presented challenges for both investors and policymakers.

Equity prices were mixed, as persistently high inflation drove investors’ expectations for higher interest rates, which particularly weighed on relatively high valuation growth stocks and economically sensitive small-capitalization stocks. Overall, small-capitalization U.S. stocks declined, while large-capitalization U.S. stocks posted a solid advance. International equities from developed markets gained slightly, although emerging market stocks declined, pressured by rising interest rates and a strengthening U.S. dollar.

The 10-year U.S. Treasury yield (which is inversely related to bond prices) rose during the reporting period as the economy expanded rapidly and inflation reached its highest annualized reading in decades. In the corporate bond market, the improving economy assuaged credit concerns and led to modest returns for high-yield corporate bonds, outpacing the negative return of investment-grade corporate bonds.

The U.S. Federal Reserve (the “Fed”) maintained accommodative monetary policy during the reporting period by keeping near-zero interest rates. However, the Fed’s tone shifted during the period, as it reduced its bond-buying program and raised the prospect of higher rates in 2022. Continued high inflation and the Fed’s new stance led many analysts to anticipate that the Fed will raise interest rates multiple times throughout the year.

Looking ahead, however, the horrific war in Ukraine has significantly clouded the outlook for the global economy. Sanctions on Russia and general wartime disruption are likely to drive already-high commodity prices even further upwards, and we have already seen spikes in energy and metal markets. While this will exacerbate inflationary pressure, it could also constrain economic growth, making the Fed’s way forward less clear. Its challenge will be combating inflation without stifling a recovery that is now facing additional supply shocks.

In this environment, we favor an overweight to equities, as we believe low interest rates and continued economic growth will support further gains, albeit likely more modest than what we saw in 2021. Sectors that are better poised to manage the transition to a lower-carbon world, such as technology and health care, are particularly attractive in the long term. U.S. and other developed market equities have room for further growth, while we believe Chinese equities stand to gain from a more accommodative monetary and fiscal environment. We are underweight long-term credit, but inflation-protected U.S. Treasuries, Asian fixed income, and emerging market local-currency bonds offer potential opportunities. We believe that international diversification and a focus on sustainability can help provide portfolio resilience, and the disruption created by the coronavirus appears to be accelerating the shift toward sustainable investments.

Overall, our view is that investors need to think globally, extend their scope across a broad array of asset classes, and be nimble as market conditions change. We encourage you to talk with your financial advisor and visit iShares.com for further insight about investing in today’s markets.

Investment-grade corporate bonds lost ground during the 12 months ended February 28, 2021 (the “reporting period”). The Markit iBoxx USD Liquid Investment Grade Index returned -3.24% for the reporting period and underperformed the -2.64% of the Bloomberg U.S. Aggregate Bond Index, a broad measure of the overall bond market.

The market downturn reflected a shift from an environment dominated by the adverse economic effects of COVID-19 to one characterized by improving growth and rising inflation. As vaccines were rolled out and lockdowns related to the virus gradually eased, economic growth rebounded in kind. U.S. GDP rose 5.7% in real (after-inflation) terms in 2021, up from -3.4% in 2020. However, the supply of goods and labor was insufficient to keep up with the increase in demand. These circumstances translated to a surge in inflation, with sharply rising prices for commodities, consumer products, housing costs and labor. Inflation, as measured by the U.S. Core Personal Consumption Index, moved north of 4% in October 2021 and exceeded 5% in January 2022 – well above its range of recent years.

The U.S. Federal Reserve (“Fed”) at first did not adjust its monetary policy in response to accelerating inflation, calling the uptrend “transitory.” As inflation in fact persisted, the Fed shifted gears in November 2021 by announcing it would taper the stimulative bond-buying program known as quantitative easing. It also stated its intention to begin raising interest rates. Investors, appearing to sense that the Fed had fallen behind the curve in fighting inflation, soon began to price in the possibility of as many as six to seven rate increases in 2022.

Late in the period, Russia’s invasion of Ukraine led to a large increase in uncertainty and somewhat dampened expectations regarding the likely extent of Fed tightening. At the same time, commodity prices surged in anticipation that the sanctions levied on Russia would further constrict the available supply of raw materials. Expectations for future inflation therefore remained elevated as of the end of February 2022, limiting the typical benefit of “flight to quality” into higher-rated bonds.

Investment-grade corporate bonds experienced a loss and underperformed the broader market. Corporates performed well through most of 2021, when the largely favorable investment backdrop encouraged investors to take on greater risk in search of more attractive yields. Investors were also cheered by the combination of rising corporate profits and improving credit conditions more generally. Together, these factors caused corporates’ yield spreads over equivalent Treasuries to revert to their pre-global financial crisis lows by mid-2021. However, prices began to weaken and spreads started to rise during the latter half of the year in response to higher inflation and increasing U.S. Treasury yields. Corporates suffered further declines in early 2022 after Russia’s invasion of Ukraine caused investors’ appetite for risk to evaporate, erasing the category’s previous gains. As a result, yield spreads closed the period at their highest level since late 2020.

Past performance is not an indication of future results. Financial markets have experienced extreme volatility and trading in many instruments has been disrupted. These circumstances may continue for an extended period of time and may continue to affect adversely the value and liquidity of each Fund’s investments. As a result, current performance may be lower or higher than the performance data quoted. Performance data current to the most recent month-end is available at iShares.com. Performance results assume reinvestment of all dividends and capital gain distributions and do not reflect the deduction of taxes that a shareholder would pay on fund distributions or on the redemption or sale of fund shares. The investment return and principal value of shares will vary with changes in market conditions. Shares may be worth more or less than their original cost when they are redeemed or sold in the market. Performance for certain funds may reflect a waiver of a portion of investment advisory fees. Without such a waiver, performance would have been lower.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. Beginning August 10, 2020, the price used to calculate market return (“Market Price”) is the closing price. Prior to August 10, 2020, Market Price was determined using the midpoint between the highest bid and the lowest ask on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Since shares of a fund may not trade in the secondary market until after the fund’s inception, for the period from inception to the first day of secondary market trading in shares of the fund, the NAV of the fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike a fund, an index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by a fund. These expenses negatively impact fund performance. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower.

Shareholders of each Fund may incur the following charges: (1) transactional expenses, including brokerage commissions on purchases and sales of fund shares and (2) ongoing expenses, including management fees and other fund expenses. The expense examples shown (which are based on a hypothetical investment of $1,000 invested at the beginning of the period and held through the end of the period) are intended to assist shareholders both in calculating expenses based on an investment in each Fund and in comparing these expenses with similar costs of investing in other funds.

The expense examples provide information about actual account values and actual expenses. Annualized expense ratios reflect contractual and voluntary fee waivers, if any. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number under the heading entitled “Expenses Paid During Period.”

The expense examples also provide information about hypothetical account values and hypothetical expenses based on a Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in a Funds and other funds, compare the 5% hypothetical examples with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

The expenses shown in the expense examples are intended to highlight shareholders’ ongoing costs only and do not reflect any transactional expenses, such as brokerage commissions and other fees paid on purchases and sales of fund shares. Therefore, the hypothetical examples are useful in comparing ongoing expenses only and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher.

iShares Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust is organized as a Delaware statutory trust and is authorized to have multiple series or portfolios.

These financial statements relate only to the following funds (each, a “Fund” and collectively, the “Funds”):

The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. Each Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies. Below is a summary of significant accounting policies:

Investment Transactions and Income Recognition: For financial reporting purposes, investment transactions are recorded on the dates the transactions are executed. Realized gains and losses on investment transactions are determined using the specific identification method. Dividend income and capital gain distributions, if any, are recorded on the ex-dividend date. Non-cash dividends, if any, are recorded on the ex-dividend date at fair value. Interest income, including amortization and accretion of premiums and discounts on debt securities, is recognized daily on an accrual basis.

In-kind Redemptions: For financial reporting purposes, in-kind redemptions are treated as sales of securities resulting in realized capital gains or losses to the Funds. Because such gains or losses are not taxable to the Funds and are not distributed to existing Fund shareholders, the gains or losses are reclassified from accumulated net realized gain (loss) to paid-in capital at the end of the Funds’ tax year. These reclassifications have no effect on net assets or net asset value (“NAV”) per share.

Distributions: Dividends and distributions paid by each Fund are recorded on the ex-dividend dates. Distributions are determined on a tax basis and may differ from net investment income and net realized capital gains for financial reporting purposes. Dividends and distributions are paid in U.S. dollars and cannot be automatically reinvested in additional shares of the Funds. The character and timing of distributions are determined in accordance with U.S. federal income tax regulations, which may differ from U.S. GAAP.

Indemnifications: In the normal course of business, each Fund enters into contracts that contain a variety of representations that provide general indemnification. The Funds’ maximum exposure under these arrangements is unknown because it involves future potential claims against the Funds, which cannot be predicted with any certainty.

Investment Valuation Policies: Each Fund’s investments are valued at fair value (also referred to as “market value” within the financial statements) each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. Each Fund determines the fair values of its financial instruments using various independent dealers or pricing services under policies approved by the Board of Trustees of the Trust (the “Board”). If a security’s market price is not readily available or does not otherwise accurately represent the fair value of the security, the security will be valued in accordance with a policy approved by the Board as reflecting fair value. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) is the committee formed by management to develop global pricing policies and procedures and to oversee the pricing function for all financial instruments.

Fair Value Inputs and Methodologies: The following methods and inputs are used to establish the fair value of each Fund’s assets and liabilities:

If events (e.g., market volatility, company announcement or a natural disaster) occur that are expected to materially affect the value of such investment, or in the event that application of these methods of valuation results in a price for an investment that is deemed not to be representative of the market value of such investment, or if a price is not available, the investment will be valued by the Global Valuation Committee, in accordance with a policy approved by the Board as reflecting fair value (“Fair Valued Investments”). The fair valuation approaches that may be used by the Global Valuation Committee include market approach, income approach and cost approach. Valuation techniques such as discounted cash flow, use of market comparables and matrix pricing are types of valuation approaches and are typically used in determining fair value. When determining the price for Fair Valued Investments, the Global Valuation Committee, or its delegate, seeks to determine the price that each Fund might reasonably expect to receive or pay from the current sale or purchase of that asset or liability in an arm’s-length transaction. Fair value determinations shall be based upon all available factors that the Global Valuation Committee, or its delegate, deems relevant and consistent with the principles of fair value measurement. The pricing of all Fair Valued Investments is subsequently reported to the Board or a committee thereof on a quarterly basis.

Fair value pricing could result in a difference between the prices used to calculate a fund’s NAV and the prices used by the fund’s underlying index, which in turn could result in a difference between the fund’s performance and the performance of the fund’s underlying index.

Fair Value Hierarchy: Various inputs are used in determining the fair value of financial instruments. These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial reporting purposes as follows:

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. Investments classified within Level 3 have significant unobservable inputs used by the Global Valuation Committee in determining the price for Fair Valued Investments. Level 3 investments include equity or debt issued by privately held companies or funds that may not have a secondary market and/or may have a limited number of investors. The categorization of a value determined for financial instruments is based on the pricing transparency of the financial instruments and is not necessarily an indication of the risks associated with investing in those securities.

Securities Lending: Each Fund may lend its securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Fund collateral consisting of cash, an irrevocable letter of credit issued by an approved bank, or securities issued or guaranteed by the U.S. government. The initial collateral received by each Fund is required to have a value of at least 102% of the current market value of the loaned securities for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current value of the securities on loan. The market value of the loaned securities is determined at the close of each business day of the Fund and any additional required collateral is delivered to the Fund or excess collateral is returned by the Fund, on the next business day. During the term of the loan, each Fund is entitled to all distributions made on or in respect of the loaned securities but does not receive interest income on securities received as collateral. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions.

As of period end, any securities on loan were collateralized by cash and/or U.S. Government obligations. Cash collateral invested in money market funds managed by BlackRock Fund Advisors (“BFA”), the Funds’ investment adviser, or its affiliates is disclosed in the Schedule of Investments. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan, if any, are also disclosed in each Fund’s Schedule of Investments. The market value of any securities on loan and the value of any related cash collateral are disclosed in the Statements of Assets and Liabilities.

Securities lending transactions are entered into by the Funds under Master Securities Lending Agreements (each, an “MSLA”) which provide the right, in the event of default (including bankruptcy or insolvency) for the non-defaulting party to liquidate the collateral and calculate a net exposure to the defaulting party or request additional collateral. In the event that a borrower defaults, the Funds, as lender, would offset the market value of the collateral received against the market value of the securities loaned. When the value of the collateral is greater than that of the market value of the securities loaned, the lender is left with a net amount payable to the defaulting party. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of an MSLA counterparty’s bankruptcy or insolvency. Under the MSLA, absent an event of default, the borrower can resell or re-pledge the loaned securities, and the Funds can reinvest cash collateral received in connection with loaned securities. Upon an event of default, the parties’ obligations to return the securities or collateral to the other party are extinguished, and the parties can resell or re-pledge the loaned securities or the collateral received in connection with the loaned securities in order to satisfy the defaulting party’s net payment obligation for all transactions under the MSLA. The defaulting party remains liable for any deficiency.

As of period end, the following table is a summary of the securities on loan by counterparty which are subject to offset under an MSLA:

The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, each Fund benefits from a borrower default indemnity provided by BlackRock, Inc. (“BlackRock”). BlackRock’s indemnity allows for full replacement of the securities loaned to the extent the collateral received does not cover the value of the securities loaned in the event of borrower default. Each Fund could incur a loss if the value of an investment purchased with cash collateral falls below the market value of the loaned securities or if the value of an investment purchased with cash collateral falls below the value of the original cash collateral received. Such losses are borne entirely by each Fund.

Investment Advisory Fees: Pursuant to an Investment Advisory Agreement with the Trust, BFA manages the investment of each Fund’s assets. BFA is a California corporation indirectly owned by BlackRock. Under the Investment Advisory Agreement, BFA is responsible for substantially all expenses of the Funds, except (i) interest and taxes; (ii) brokerage commissions and other expenses connected with the execution of portfolio transactions; (iii) distribution fees; (iv) the advisory fee payable to BFA; and (v) litigation expenses and any extraordinary expenses (in each case as determined by a majority of the independent trustees).

For its investment advisory services to each of the following Funds, BFA is entitled to an annual investment advisory fee, accrued daily and paid monthly by the Funds, based on the average daily net assets of each Fund as follows:

Effective April 1, 2021, for its investment advisory services to the iShares Broad USD Investment Grade Corporate Bond ETF, BFA is entitled to an annual investment advisory fee of 0.04%, accrued daily and paid monthly by the Fund, based on the average daily net assets of the Fund. Prior to April 1, 2021, BFA was entitled to an annual investment advisory fee of 0.06%, accrued daily and paid monthly by the Fund, based on the average daily net assets of the Fund.

For its investment advisory services to the iShares 1-5 Year Investment Grade Corporate Bond ETF, iShares 5-10 Year Investment Grade Corporate Bond ETF and iShares 10+ Year Investment Grade Corporate Bond ETF, BFA is entitled to an annual investment advisory fee, accrued daily and paid monthly by the Fund, based on the Fund’s allocable portion of the aggregate of the average daily net assets of the Fund and certain other iShares funds, as follows:

Distributor: BlackRock Investments, LLC, an affiliate of BFA, is the distributor for each Fund. Pursuant to the distribution agreement, BFA is responsible for any fees or expenses for distribution services provided to the Funds.

Securities Lending: The U.S. Securities and Exchange Commission (the “SEC”) has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Funds, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to securities lending, including any custodial costs. Each Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan (the “collateral investment fees”). The cash collateral is invested in a money market fund, BlackRock Cash Funds: Institutional or BlackRock Cash Funds: Treasury, managed by BFA, or its affiliates. However, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees each Fund bears to an annual rate of 0.04%. The SL Agency Shares of such money market fund will not be subject to a sales load, distribution fee or service fee. The money market fund in which the cash collateral has been invested may, under certain circumstances, impose a liquidity fee of up to 2% of the value redeemed or temporarily restrict redemptions for up to 10 business days during a 90 day period, in the event that the money market fund’s weekly liquid assets fall below certain thresholds.

Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. Each Fund retains a portion of securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent.

Pursuant to the current securities lending agreement, each Fund retains 82% of securities lending income (which excludes collateral investment fees), and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

In addition, commencing the business day following the date that the aggregate securities lending income plus the collateral investment fees generated across all 1940 Act iShares exchange-traded funds (the “iShares ETF Complex”) in that calendar year exceeds a specified threshold, each Fund, pursuant to the securities lending agreement, will retain for the remainder of that calendar year 85% of securities lending income (which excludes collateral investment fees) and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

The share of securities lending income earned by each Fund is shown as securities lending income – affiliated – net in its Statements of Operations. For the year ended February 28, 2022, the Funds paid BTC the following amounts for securities lending agent services:

Officers and Trustees: Certain officers and/or trustees of the Trust are officers and/or trustees of BlackRock or its affiliates.

Other Transactions: Cross trading is the buying or selling of portfolio securities between funds to which BFA (or an affiliate) serves as investment adviser. At its regularly scheduled quarterly meetings, the Board reviews such transactions as of the most recent calendar quarter for compliance with the requirements and restrictions set forth by Rule 17a-7.

For the year ended February 28, 2022, transactions executed by the Funds pursuant to Rule 17a-7 under the 1940 Act were as follows:

Each Fund may invest its positive cash balances in certain money market funds managed by BFA or an affiliate. The income earned on these temporary cash investments is shown as dividends – affiliated in the Statements of Operations.

A fund, in order to improve its portfolio liquidity and its ability to track its underlying index, may invest in shares of other iShares funds that invest in securities in the fund’s underlying index.

For the year ended February 28, 2022, purchases and sales of investments, excluding short-term investments and in-kind transactions, were as follows:

Each Fund is treated as an entity separate from the Trust’s other funds for federal income tax purposes. It is each Fund’s policy to comply with the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute substantially all of its taxable income to its shareholders. Therefore, no U.S. federal income tax provision is required.

Management has analyzed tax laws and regulations and their application to the Funds as of February 28, 2022, inclusive of the open tax return years, and does not believe that there are any uncertain tax positions that require recognition of a tax liability in the Funds’ financial statements.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. As of February 28, 2022, permanent differences attributable to nondeductible expenses, certain deemed distributions and realized gains (losses) from in-kind redemptions were reclassified to the following accounts:

As of February 28, 2022, the tax components of accumulated net earnings (losses) were as follows:

For the year ended February 28, 2022, the Funds listed below utilized the following amounts of their respective capital loss carryforwards:

As of February 28, 2022, gross unrealized appreciation and depreciation based on cost of investments (including short positions and derivatives, if any) for U.S. federal income tax purposes were as follows:

In the normal course of business, each Fund invests in securities or other instruments and may enter into certain transactions, and such activities subject the Fund to various risks, including, among others, fluctuations in the market (market risk) or failure of an issuer to meet all of its obligations. The value of securities or other instruments may also be affected by various factors, including, without limitation: (i) the general economy; (ii) the overall market as well as local, regional or global political and/or social instability; (iii) regulation, taxation or international tax treaties between various countries; or (iv) currency, interest rate or price fluctuations. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the Funds and their investments. Each Fund’s prospectus provides details of the risks to which the Fund is subject.

BFA uses a “passive” or index approach to try to achieve each Fund’s investment objective following the securities included in its underlying index during upturns as well as downturns. BFA does not take steps to reduce market exposure or to lessen the effects of a declining market. Divergence from the underlying index and the composition of the portfolio is monitored by BFA.

The Funds may be exposed to additional risks when reinvesting cash collateral in money market funds that do not seek to maintain a stable NAV per share of $1.00, which may be subject to redemption gates or liquidity fees under certain circumstances.

Market Risk: Each Fund may be exposed to prepayment risk, which is the risk that borrowers may exercise their option to prepay principal earlier than scheduled during periods of declining interest rates, which would force each Fund to reinvest in lower yielding securities. Each Fund may also be exposed to reinvestment risk, which is the risk that income from each Fund’s portfolio will decline if each Fund invests the proceeds from matured, traded or called fixed-income securities at market interest rates that are below each Fund portfolio’s current earnings rate.

An outbreak of respiratory disease caused by a novel coronavirus has developed into a global pandemic and has resulted in closing borders, quarantines, disruptions to supply chains and customer activity, as well as general concern and uncertainty. The impact of this pandemic, and other global health crises that may arise in the future, could affect the economies of many nations, individual companies and the market in general in ways that cannot necessarily be foreseen at the present time. This pandemic may result in substantial market volatility and may adversely impact the prices and liquidity of a fund’s investments. Although vaccines have been developed and approved for use by various governments, the duration of this pandemic and its effects cannot be determined with certainty.

Counterparty Credit Risk: The Funds may be exposed to counterparty credit risk, or the risk that an entity may fail to or be unable to perform on its commitments related to unsettled or open transactions, including making timely interest and/or principal payments or otherwise honoring its obligations. The Funds manage counterparty credit risk by entering into transactions only with counterparties that the Manager believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the Funds to market, issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of the Funds’ exposure to market, issuer and counterparty credit risks with respect to these financial assets is approximately their value recorded in the Statements of Assets and Liabilities, less any collateral held by the Funds.

Concentration Risk: A diversified portfolio, where this is appropriate and consistent with a fund’s objectives, minimizes the risk that a price change of a particular investment will have a material impact on the NAV of a fund. The investment concentrations within each Fund’s portfolio are disclosed in its Schedule of Investments.

The Funds invest a significant portion of their assets in fixed-income securities and/or use derivatives tied to the fixed-income markets. Changes in market interest rates or economic conditions may affect the value and/or liquidity of such investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. The Funds may be subject to a greater risk of rising interest rates due to the current period of historically low rates.

Significant Shareholder Redemption Risk: Certain shareholders may own or manage a substantial amount of fund shares and/or hold their fund investments for a limited period of time. Large redemptions of fund shares by these shareholders may force a Fund to sell portfolio securities, which may negatively impact the fund’s NAV, increase the fund’s brokerage costs, and/or accelerate the realization of taxable income/gains and cause the fund to make additional taxable distributions to shareholders.

LIBOR Transition Risk: The United Kingdom’s Financial Conduct Authority announced a phase out of the London Interbank Offered Rate (“LIBOR”). Although many LIBOR rates ceased to be published or no longer are representative of the underlying market they seek to measure after December 31, 2021, a selection of widely used USD LIBOR rates will continue to be published through June 2023 in order to assist with the transition. The Funds may be exposed to financial instruments tied to LIBOR to determine payment obligations, financing terms, hedging strategies or investment value. The transition process away from LIBOR might lead to increased volatility and illiquidity in markets for, and reduce the effectiveness of new hedges placed against, instruments whose terms currently include LIBOR. The ultimate effect of the LIBOR transition process on the Funds is uncertain.

Capital shares are issued and redeemed by each Fund only in aggregations of a specified number of shares or multiples thereof (“Creation Units”) at NAV. Except when aggregated in Creation Units, shares of each Fund are not redeemable.

The consideration for the purchase of Creation Units of a fund in the Trust generally consists of the in-kind deposit of a designated portfolio of securities and a specified amount of cash. Certain funds in the Trust may be offered in Creation Units solely or partially for cash in U.S. dollars. Investors purchasing and redeeming Creation Units may pay a purchase transaction fee and a redemption transaction fee directly to State Street Bank and Trust Company, the Trust’s administrator, to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units, including Creation Units for cash. Investors transacting in Creation Units for cash may also pay an additional variable charge to compensate the relevant fund for certain transaction costs (i.e., stamp taxes, taxes on currency or other financial transactions, and brokerage costs) and market impact expenses relating to investing in portfolio securities. Such variable charges, if any, are included in shares sold in the table above.

From time to time, settlement of securities related to in-kind contributions or in-kind redemptions may be delayed. In such cases, securities related to in-kind transactions are reflected as a receivable or a payable in the Statements of Assets and Liabilities.

Management has evaluated the impact of all subsequent events on the Funds through the date the financial statements were available to be issued and has determined that there were no subsequent events requiring adjustment or additional disclosure in the financial statements.

Shareholders of iShares BBB Rated Corporate Bond ETF, iShares Broad USD Investment Grade Corporate

Bond ETF, iShares 1-5 Year Investment Grade Corporate Bond ETF, iShares 5-10 Year Investment Grade

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of iShares BBB Rated Corporate Bond ETF, iShares Broad USD Investment Grade Corporate Bond ETF, iShares 1-5 Year Investment Grade Corporate Bond ETF, iShares 5-10 Year Investment Grade Corporate Bond ETF and iShares 10+ Year Investment Grade Corporate Bond ETF (five of the funds constituting iShares Trust, hereafter collectively referred to as the “Funds”) as of February 28, 2022, the related statements of operations and changes in net assets for each of the periods indicated in the table below, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of February 28, 2022, the results of each of their operations and changes in each of their net assets for each of the periods indicated in the table below and each of the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.

These financial statements are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of February 28, 2022 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

We have served as the auditor of one or more BlackRock investment companies since 2000.

The Funds hereby designate the following amounts, or maximum amounts allowable by law, as capital gain dividends, subject to a long-term capital gains tax rate as noted below, for the fiscal year ended February 28, 2022:

The Funds hereby designate the following amounts, or maximum amounts allowable by law, of distributions from direct federal obligation interest for the fiscal year ended February 28, 2022:

The law varies in each state as to whether and what percent of ordinary income dividends attributable to federal obligations is exempt from state income tax. Shareholders are advised to check with their tax advisers to determine if any portion of the dividends received is exempt from state income tax.

The Funds hereby designate the following amounts, or maximum amounts allowable by law, as interest income eligible to be treated as a Section 163(j) interest dividend for the fiscal year ended February 28, 2022:

The Funds hereby designate the following amounts, or maximum amounts allowable by law, as interest-related dividends eligible for exemption from U.S. withholding tax for nonresident aliens and foreign corporations for the fiscal year ended February 28, 2022:

In compliance with Rule 22e-4 under the Investment Company Act of 1940, as amended (the “Liquidity Rule”), iShares Trust (the “Trust”) has adopted and implemented a liquidity risk management program (the “Program”) for iShares BBB Rated Corporate Bond ETF, iShares Broad USD Investment Grade Corporate Bond ETF, iShares 1-5 Year Investment Grade Corporate Bond ETF, iShares 5-10 Year Investment Grade Corporate Bond ETF and iShares 10+ Year Investment Grade Corporate Bond ETF (the “Funds” or “ETFs”), each a series of the Trust, which is reasonably designed to assess and manage each Fund’s liquidity risk.

The Board of Trustees (the “Board”) of the Trust, on behalf of the Funds, met on December 9, 2021 (the “Meeting”) to review the Program. The Board previously appointed BlackRock Fund Advisors (“BlackRock”), the investment adviser to the Funds, as the program administrator for each Fund’s Program. BlackRock also previously delegated oversight of the Program to the 40 Act Liquidity Risk Management Committee (the “Committee”). At the Meeting, the Committee, on behalf of BlackRock, provided the Board with a report that addressed the operation of the Program and assessed its adequacy and effectiveness of implementation, including the management of each Fund’s Highly Liquid Investment Minimum (“HLIM”) where applicable, and any material changes to the Program (the “Report”). The Report covered the period from October 1, 2020 through September 30, 2021 (the “Program Reporting Period”).

The Report described the Program’s liquidity classification methodology for categorizing each Fund’s investments (including derivative transactions) into one of four liquidity buckets. It also referenced the methodology used by BlackRock to establish each Fund’s HLIM and noted that the Committee reviews and ratifies the HLIM assigned to each Fund no less frequently than annually. The Report also discussed notable events affecting liquidity over the Program Reporting Period, including extended market holidays and the imposition of capital controls in certain non-U.S. countries.

The Report noted that the Program complied with the key factors for consideration under the Liquidity Rule for assessing, managing and periodically reviewing each Fund’s liquidity risk, as follows:

As part of BlackRock’s continuous review of the effectiveness of the Program, the Committee made the following material changes to the Program: (1) updates to certain model components in the Program’s methodology; and (2) certain iShares Funds entered into a $800 million credit agreement with a group of lenders that replaced a previous liquidity facility. The Report provided to the Board stated that the Committee concluded that based on the operation of the functions, as described in the Report, the Program is operating as intended and is effective in implementing the requirements of the Liquidity Rule.

The amounts and sources of distributions reported are estimates and are being provided pursuant to regulatory requirements and are not being provided for tax reporting purposes. The actual amounts and sources for tax reporting purposes will depend upon each Fund’s investment experience during the year and may be subject to changes based on tax regulations. Shareholders will receive a Form 1099-DIV each calendar year that will inform them how to report these distributions for federal income tax purposes.

Information on the Fund’s net asset value, market price, premiums and discounts, and bid-ask spreads can be found at iShares.com.

The Alternative Investment Fund Managers Directive and the Alternative Investment Fund Managers Regulations 2013 (as amended) and the “Guidelines on sound remuneration policies under the AIMFD” issued by the European Securities and Markets Authority (together the “Regulations”) impose detailed and prescriptive obligations on fund managers established in the European Union (the “EU”) and the UK. These do not currently apply to managers established outside of the EU or UK, such as BFA (the “Company”). Rather, non-EU and non-UK managers are only required to comply with certain disclosure, reporting and transparency obligations of the Regulations if such managers market a fund to EU investors.

The Company has registered the iShares 1-5 Year Investment Grade Corporate Bond ETF and the iShares 5-10 Year Investment Grade Corporate Bond ETF (each a “Fund”, collectively the “Funds”) to be marketed to EU investors in the United Kingdom, the Netherlands, Finland, Sweden, and Luxembourg.

The Company is required under the Regulations to make quantitative disclosures of remuneration. These disclosures are made in line with BlackRock’s interpretation of currently available regulatory guidance on quantitative remuneration disclosures. As market or regulatory practice develops BlackRock may consider it appropriate to make changes to the way in which quantitative remuneration disclosures are calculated. Where such changes are made, this may result in disclosures in relation to a fund not being comparable to the disclosures made in the prior year, or in relation to other BlackRock fund disclosures in that same year.

Disclosures are provided in relation to (a) the staff of the Company; (b) staff who are senior management; and (c) staff who have the ability to materially affect the risk profile of the Funds.

All individuals included in the aggregated figures disclosed are rewarded in line with BlackRock’s remuneration policy for their responsibilities across the relevant BlackRock business area. As all individuals have a number of areas of responsibilities, only the portion of remuneration for those individuals’ services attributable to the Funds is included in the aggregate figures disclosed.

BlackRock has a clear and well defined pay-for-performance philosophy, and compensation programmes which support that philosophy.

BlackRock operates a total compensation model for remuneration which includes a base salary, which is contractual, and a discretionary bonus scheme. Although all employees are eligible to receive a discretionary bonus, there is no contractual obligation to make a discretionary bonus award to any employees. For senior management, a significant percentage of variable remuneration is deferred over time. All employees are subject to a claw-back policy.

Remuneration decisions for employees are made once annually in January following the end of the performance year, based on BlackRock’s full-year financial results and other non-financial goals and objectives. Alongside financial performance, individual total compensation is also based on strategic and operating results and other considerations such as management and leadership capabilities. No set formulas are established and no fixed benchmarks are used in determining annual incentive awards.

Annual incentive awards are paid from a bonus pool which is reviewed throughout the year by BlackRock’s independent compensation committee, taking into account both actual and projected financial information together with information provided by the Enterprise Risk and Regulatory Compliance departments in relation to any activities, incidents or events that warrant consideration in making compensation decisions. Individuals are not involved in setting their own remuneration.

Each of the control functions (Enterprise Risk, Legal & Compliance, and Internal Audit) each have their own organisational structures which are independent of the business units. Functional bonus pools for those control functions are determined with reference to the performance of each individual function and the remuneration of the senior members of control functions is directly overseen by BlackRock’s independent remuneration committee.

Members of staff and senior management of the Company typically provide both AIFMD and non-AIFMD related services in respect of multiple funds, clients and functions of the Company and across the broader BlackRock group. Therefore, the figures disclosed are a sum of each individual’s portion of remuneration attributable to the Funds according to an objective apportionment methodology which acknowledges the multiple-service nature of the Company. Accordingly the figures are not representative of any individual’s actual remuneration or their remuneration structure.

The amount of total & aggregate remuneration awarded by the company to its staff which has been attributed to the funds in respect of the company’s financial year ending December 31, 2021 were as follows:

The Board of Trustees has responsibility for the overall management and operations of the Funds, including general supervision of the duties performed by BFA and other service providers. Each Trustee serves until he or she resigns, is removed, dies, retires or becomes incapacitated. Each officer shall hold office until his or her successor is elected and qualifies or until his or her death, resignation or removal. Trustees who are not “interested persons” (as defined in the 1940 Act) of the Trust are referred to as independent trustees (“Independent Trustees”).

The registered investment companies advised by BFA or its affiliates (the “BlackRock-advised Funds”) are organized into one complex of open-end equity, multi-asset, index and money market funds and ETFs (the “BlackRock Multi-Asset Complex”), one complex of closed-end funds and open-end non-index fixed-income funds (including ETFs) (the “BlackRock Fixed-Income Complex”) and one complex of ETFs (“Exchange-Traded Fund Complex”) (each, a “BlackRock Fund Complex”). Each Fund is included in the Exchange-Traded Fund Complex. Each Trustee also serves as a Director of iShares, Inc. and a Trustee of iShares U.S. ETF Trust and, as a result, oversees all of the funds within the Exchange-Traded Fund Complex, which consists of 374 funds as of February 28, 2022. With the exception of Robert S. Kapito, Salim Ramji and Charles Park, the address of each Trustee and officer is c/o BlackRock, Inc., 400 Howard Street, San Francisco, CA 94105.
