Investment Objective

The iShares New York Muni Bond ETF (the "Fund") seeks to track the investment results of an index substantially composed of investment-grade municipal bonds issued in the State of New York.

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. Amounts in the table are rounded to the nearest basis point, which in some cases may be "0.00."  The investment advisory agreement between iShares Trust (the "Trust") and BlackRock Fund Advisors ("BFA") (the "Investment Advisory Agreement") provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and any extraordinary expenses.

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

 

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)1,2
Management Fee	0.09 %
Other Expenses	0.00 %
Total Annual Fund Operating Expenses	0.09 %

1The expense information in the table has been restated to reflect current fees.

2Operating expenses paid by BFA under the Investment Advisory Agreement exclude acquired fund fees and expenses, if any.

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:

 

Expense Example	1 Year	3 Years	5 Years	10 Years
Example Fund Costs	$9	$29	$51	$115

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 9% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to track the investment results of the ICE® AMT-Free New York Plus Municipal Index (the "Underlying Index"), which generally measures the performance of U.S. dollar denominated investment grade tax-exempt debt publicly issued in the U.S. domestic market by the state of New York and its political subdivisions. The Underlying Index includes a 5% weighting to U.S. dollar denominated investment grade tax-exempt debt publicly issued in the U.S. domestic market by states other than New York and such states' political subdivisions. As of February 28, 2026, there were 6,725 issues from New York and 21,700 issues from U.S. states excluding New York in the Underlying Index. As of February 28, 2026, a significant portion of the Underlying Index was represented by municipal bonds. The components of the Underlying Index are likely to change over time.

The Underlying Index includes municipal bonds issued in the State of New York (the "State" or "New York"), the interest of which is exempt from Federal income taxes and not subject to alternative minimum tax. Each bond in the Underlying Index must have a rating of at least BBB- by Standard & Poor's® Global Ratings, Baa3 by Moody's Investors Service, Inc., or BBB- by Fitch Ratings, Inc. A bond must be rated by at least one of these three rating agencies in order to qualify for the Underlying Index, and the lowest rating will be used in determining if the bond is investment grade. Each bond in the Underlying Index must be a constituent of an offering where the original offering amount was at least $20 million and have a minimum par amount (i.e., currently outstanding face value) of $5 million. In addition, each bond must have a minimum remaining term to final maturity greater than or equal to one calendar month to be included in the Underlying Index. The Underlying Index also includes municipal bonds issued in U.S. states other than New York that are subject to the same selection criteria. The Underlying Index is a market-value weighted index and is subject to a capping methodology that aims at reducing index concentration. The Underlying Index is rebalanced on the last calendar day of the month.

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

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

BFA uses a representative sampling indexing strategy to manage the Fund. "Representative sampling" is an indexing strategy that involves investing in a representative sample of securities or other instruments that collectively has an investment profile similar to that of an applicable underlying index. The instruments selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and industry weightings), fundamental characteristics (such as return variability, duration (i.e., an instrument's price sensitivity to a change in interest rates), maturity or credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the components of the Underlying Index.

The Fund will invest at least 80% of its assets in the component securities of the Underlying Index, and the Fund will invest at least 90% of its assets in fixed income securities of the types included in the Underlying Index that BFA believes will help the Fund track the Underlying Index. The Fund will invest no more than 10% of its assets in futures, options and swaps contracts that BFA believes will help the Fund track the Underlying Index as well as in fixed income securities other than the types 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 generally holds municipal bond securities issued by New York and its municipalities whose interest payments are exempt from U.S. federal and New York state income taxes and the federal alternative minimum tax ("AMT"). As of the date of this Prospectus, interest that is exempt from U.S. federal income tax is also exempt from the federal Medicare contribution tax of 3.8% on "net investment income." In addition, the Fund intends to invest any cash assets in one or more affiliated municipal money market funds, which may be advised by BFA or its affiliates. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Underlying Index is sponsored by ICE Data Indices, LLC (the "Index Provider" or "IDI"), which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the components of 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), repurchase agreements collateralized by U.S. government securities, and securities of state or municipal governments and their political subdivisions are not considered to be issued by members of any industry.

Summary of Principal Risks

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

New York Municipal Securities Risk. Investing in New York municipal securities subjects the Fund to legal, regulatory, fiscal, political, economic and other risks that are specific to New York and its agencies, public authorities and political subdivisions. Unfavorable developments in any economic sector or disruptions in the broader municipal market, among other factors, may adversely impact the Fund's investments.

Municipal Securities Risk. Municipal securities are subject to the risk that the issuer may be unable to pay the instrument's obligations, which would adversely affect the value of the securities. Legal, regulatory, fiscal, political, economic and other developments may also adversely affect the value of municipal securities. When municipal securities depend on a specific revenue source to fund their payment obligations, the value of such securities may fluctuate as a result of actual or anticipated changes in the cash flows from the revenue source or changes in the priority of the municipal obligation to receive the cash flows. If a security loses its tax-exempt status, its value may decline significantly.

The market for municipal bonds may be less liquid than for other types of debt securities, and it may be harder for the Fund to buy and sell municipal bonds, especially on short notice. There may be less publicly available information about the financial condition of municipal security issuers than for issuers of other types of securities. As a result, municipal securities may be more difficult to value accurately. A default or insolvency of certain issuers of municipal bonds may be subject to proceedings that are significantly different from corporate bankruptcy proceedings, and the Fund's ability to recover assets may be limited.

Interest Rate Risk. Interest rate risk refers to the risk of fluctuations in the value of a fixed-income security due to changes in the general level of interest rates. Interest rate changes can be sudden and unpredictable and are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply and demand for fixed-income securities. An increase in interest rates generally will cause the value of fixed-income securities to decline. Securities with longer maturities generally are more sensitive to interest rate changes and subject to greater fluctuations in value. Changes in interest rates may have unpredictable effects on fixed-income markets and result in heightened volatility and lower liquidity for certain instruments, which may adversely affect a Fund's performance. During periods of very low or negative interest rates, a Fund may be unable to maintain positive returns or pay dividends to shareholders.

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

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

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

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

Call Risk. During periods of falling interest rates, an issuer of a callable debt obligation held by the Fund may "call" or repay the debt obligation before its stated maturity, and the Fund may have to reinvest the proceeds in instruments with lower yields, which would result in a decline in the Fund's income, or in instruments 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 investments are concentrated in the securities or other assets of one or more issuers, countries or other geographic units, markets, industries, project types, or asset classes.

Credit Risk. Credit risk is the risk that an issuer, guarantor or liquidity provider of a fixed-income security may be unable or unwilling, or may be perceived as unable or unwilling, to make timely principal and/or interest payments or to otherwise honor

its obligations. The credit rating assigned to a security or its issuer does not necessarily reflect the issuer's current financial condition or an investment's volatility or liquidity. An actual or perceived decline in an issuer's creditworthiness may result in a decrease in the value and liquidity of its securities as well as greater price volatility, which may make it difficult to sell the securities. The Fund may be adversely affected if an investment that it holds experiences a downgrade or a default.

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

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

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

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

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

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

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

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

Tax Risk. There is no guarantee that the Fund's income will be exempt from U.S. federal, state or local income taxes, the federal AMT or the federal Medicare contribution tax of 3.8% on "net investment income." Neither BFA nor the Fund guarantees that an opinion from bond counsel about a security's tax-exempt status is correct, and there is no assurance that the Internal Revenue Service ("IRS") will agree with the bond counsel's opinion. Events occurring after a municipal bond is

issued or acquired by a Fund may result in a determination that the bond's interest is includible in gross income, retroactively to the bond's date of issuance, for purposes of U.S. federal income taxes, the federal AMT or the federal Medicare contribution tax. The interest on money market instruments, other cash equivalents and derivatives held by a Fund may be subject to federal, state and local income taxes and the federal Medicare contribution tax.

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

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

Performance Information

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

1The Fund began comparing its performance to the ICE BofA US Municipal Securities Index on February 28, 2026, as it represents the US national municipal securities market, and will no longer compare its performance to the ICE AMT-Free US National Municipal Index effective approximately one year from February 28, 2026.

2The ICE AMT-Free New York Plus Municipal Index (Spliced) reflects the performance of the S&P New York AMT-Free Municipal Bond Index through September 14, 2021 and the ICE AMT-Free New York Plus Municipal Index thereafter, which reflect the times when each index was the Underlying Index of the Fund.

3The inception date of the ICE AMT-Free US National Municipal Index was June 10, 2021.

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

Purchase and Sale of Fund Shares

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

Tax Information

The Fund intends to make distributions primarily from net tax-exempt income, although distributions of taxable capital gains may also occur. The Fund is generally not an appropriate investment for a 401(k) plan or an IRA. Please consult your personal tax advisor.

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.
