iSHARES^® INFLATION HEDGED CORPORATE BOND ETF

Ticker: LQDI

Stock Exchange: Cboe BZX

Investment Objective

The iShares Inflation Hedged Corporate Bond ETF (the “Fund”) seeks to mitigate the inflation risk of a portfolio composed of U.S. dollar-denominated, investment-grade corporate bonds.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares U.S. ETF Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except the management fees, interest expenses, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, litigation expenses and 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 by investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees so that the Fund’s total annual fund operating expenses after fee waiver is equal to the Acquired Fund Fees and Expenses attributable to the Fund’s investment in the iShares iBoxx $ Investment Grade Corporate Bond ETF (“LQD” or the “Underlying Fund”), after taking into account any fee waivers by LQD, plus 0.05% through February 28, 2023. The contractual waiver may be terminated prior to February 28, 2023 only upon written agreement of the Trust and BFA.

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

Annual Fund Operating Expenses (ongoing expenses that you pay each year as a percentage of the value of your investments)

Management Fees

Distribution and Service (12b-1) Fees

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

1 Year		3 Years		5 Years		10 Years
$19		$61		$143		$384

Portfolio Turnover. The Fund and the Underlying Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate for the Fund or the Underlying Fund may indicate higher transaction costs and may cause the Fund or the Underlying Fund to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to the Underlying Fund included as part of Acquired Fund Fees and Expenses), affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 0% of the average value of its portfolio. To the extent the Underlying Fund incurs costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets in the Underlying Fund, U.S. dollar-denominated investment-grade corporate bonds, in one or more other underlying funds that principally invest in investment-grade corporate

bonds, and in inflation swaps. The Fund intends to invest a substantial portion of its assets in the Underlying Fund. The Fund attempts to mitigate the inflation risk of the underlying securities or the Underlying Fund (as determined by BFA) primarily through the use of inflation swaps (i.e., contracts in which the Fund will make fixed-rate payments based on notional amount while receiving floating-rate payments determined from an inflation index), which are managed on an active basis. The Fund may also invest in other instruments designed to transfer inflation risk from one party to another, including but not limited to Treasury Inflation Protected Securities (“TIPS”), total return swaps, credit default swaps, interest rate swaps and U.S. Treasury futures (collectively with inflation swaps, “inflation hedging instruments”). The Fund’s investments in inflation hedging instruments are not intended to mitigate credit risk or other factors influencing the price of investment-grade corporate bonds, which may have a greater impact on the bonds' returns than inflation rates. Moreover, to the extent that inflation risk has been priced into the investment-grade corporate bonds owned by the Fund or the Underlying Fund, the Fund will underperform the Underlying Fund even during inflationary periods.

The Fund is an actively managed exchange-traded fund (“ETF”) that does not seek to replicate the performance of a specified index.

The Fund may also invest in other ETFs (including the Underlying Fund and other iShares funds), U.S. government securities, futures, options and swap contracts, short-term paper, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may have a higher degree of portfolio turnover than funds that seek to replicate the performance of an index.

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

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below (either directly or through its investments in the Underlying Fund), any of which may adversely affect the Fund's NAV, trading price, yield, total return and ability to meet its investment objective. Unlike many ETFs, the Fund is not an index-based ETF. The order of the below risk factors does not indicate the significance of any particular risk factor.

Asset Class Risk. Securities and other assets in the Fund's or the Underlying Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.

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

Authorized Participant Concentration Risk. Only an Authorized Participant 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 Creation Units (as defined in the Purchase and Sale of Fund Shares section of the Prospectus), 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.

Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund or the Underlying

S-3

---

 

Fund may “call” or repay the security before its stated maturity, and the Fund or the Underlying Fund may have to reinvest the proceeds in securities with lower yields, which would result in a decline in the Fund's or Underlying Fund's income, or in securities with greater risks or with other less favorable features.

Cash Management Risk. If a significant amount of the Fund’s assets are invested in cash and cash equivalents, it will be more difficult for the Fund to achieve its investment objective. The Fund may underperform other funds that do not similarly invest in cash and cash equivalents for investment purposes and/or to collateralize derivative instruments.

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 the 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 or asset class.

Consumer Staples Sector Risk. The consumer staples sector may be affected by, among other things, marketing campaigns, changes in consumer demands, government regulations and changes in commodity prices.

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 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.

Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund or the Underlying Fund, the Fund's or the Underlying Fund's adviser, distributor, or other service providers (including the benchmark provider), market makers, Authorized Participants, hedging counterparties to the Fund or the issuers of securities in which the Fund or the Underlying 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 service providers, market makers, Authorized Participants, hedging counterparties to the Fund or issuers of securities in which the Fund or the Underlying Fund invests.

Derivatives Risk. The Fund’s or Underlying Fund's use of derivatives may reduce the Fund’s or Underlying Fund's returns or increase volatility. Volatility is defined as the characteristic of a security, a currency, an index or a market to fluctuate significantly in price within a short time period. Derivatives may also be subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. Counterparty

S-4

---

 

risk for over-the-counter (“OTC”) derivatives is generally higher than that for derivatives traded on an exchange or through a clearing house. A risk of the Fund’s or Underlying Fund's use of derivatives is that the fluctuations in their values may not correlate perfectly with the value of the underlying asset, the performance of the asset class to which the Fund or Underlying Fund seeks exposure or the performance of the overall markets. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund or Underlying Fund to sell or otherwise close a derivatives position could expose the Fund or Underlying Fund to losses and could make derivatives more difficult for the Fund or Underlying Fund to value accurately. The Fund or Underlying Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, or movements between the time of periodic reallocations of Fund or Underlying Fund assets, which losses are potentially unlimited. Certain derivatives may give rise to a form of leverage and may expose the Fund or Underlying Fund to greater risk and increase its costs. The impact of U.S. and global regulation of derivatives may make derivatives more costly, may limit the availability of derivatives, may delay or restrict the exercise by the Fund or Underlying Fund of termination rights or remedies upon a counterparty default under derivatives held by the Fund or Underlying Fund (which could result in losses), or may otherwise adversely affect the value or performance of derivatives.

Financials Sector Risk. 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, and decreased liquidity in credit markets. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. The impact of changes in capital requirements and recent or future regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. In recent years, cyberattacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses to companies in this sector, which may negatively impact the Fund.

Geographic Risk. A natural disaster could occur in a geographic region in which the Fund or the 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 the Underlying Fund's investments in, or which are exposed to, the affected region.

Hedging Risk. The Fund seeks to mitigate the potential impact of inflation on the performance of investment-grade corporate bonds by investing in inflation hedging instruments. The Fund’s use of inflation hedging instruments is intended solely to mitigate inflation risk and is not intended to mitigate credit risk, interest rate risk, or other factors influencing the price of investment-grade corporate bonds, which may have a greater impact on the bonds’ returns than inflation. There is no guarantee that the Fund’s positions in inflation hedging instruments will completely eliminate the inflation risk of the long positions in

S-5

---

 

investment-grade corporate bonds. In addition, when interest rates rise above the inflation rate, the Fund’s investments will generally underperform a portfolio comprised solely of the investment-grade corporate bonds. In certain low inflation rate environments, the Fund’s hedging strategy could result in disproportionately larger losses in the positions in inflation hedging instruments as compared to gains in the long investment-grade corporate bond positions attributable to interest rate changes. The Fund only seeks to hedge the impact of inflation and, as a result, if floating interest rates rise above the inflation-linked rates, the Fund will not be hedged. There is no guarantee the Fund will have positive returns, even in environments of sharply rising inflation rates in which the Fund’s positions in inflation hedging instruments might be expected to mitigate the effects of such rises. The Fund will incur expenses when entering into positions in inflation hedging instruments. Moreover, to the extent that inflation risk has been priced into the investment-grade corporate bonds owned by the Fund or the Underlying Fund, the Fund will underperform the Underlying Fund even during inflationary periods.

Illiquid Investments Risk. The Fund may invest up to an aggregate amount of 15% of its net assets in illiquid investments. An illiquid investment is any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without significantly changing the market value of the investment. To the extent the Fund holds illiquid investments, the illiquid investments may reduce the returns of the Fund because the Fund may be unable to

transact at advantageous times or prices. During periods of market volatility, liquidity in the market for the Fund’s shares may be impacted by the liquidity in the market for the underlying securities or instruments held by the Fund, which could lead to the Fund’s shares trading at a premium or discount to the Fund’s NAV.

Income Risk. The Fund’s income may decline when interest rates fall because the Fund may hold a significant portion of short duration securities and/or securities that have floating or variable interest rates. The Fund’s income may decline because the Fund invests in lower yielding bonds, and as the bonds in its portfolio mature, are near maturity or are called, the Fund needs to purchase additional bonds.

Infectious Illness Risk. An outbreak of an infectious respiratory illness, COVID-19, caused by a novel coronavirus has resulted in travel restrictions, disruption of healthcare systems, prolonged quarantines, cancellations, supply chain disruptions, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic impacts. Certain markets have experienced temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. These events will have an impact on the Fund and its investments and could impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund’s net asset value. Other infectious illness outbreaks in the future may result in similar impacts.

Inflation-Linked Instruments Risk. There can be no assurance that the Consumer Price Index (“CPI”), which typically is referenced by inflation

S-6

---

 

swaps, or any other inflation index will accurately measure the rate of inflation experienced in the U.S. or the rate of expected future inflation reflected in the prices and yields of bonds held by the Fund. CPI swaps may cause the Fund’s NAV and returns to be more volatile and expose the Fund to counterparty risk. The Fund could lose money on both the inflation hedging instruments and the investment-grade corporate bonds, and the present value of the Fund’s portfolio investments could decrease if inflation increases.

Inflation Risk. The Fund seeks to mitigate many of the adverse impacts of inflation on investment-grade corporate bonds held by the Fund and their issuers primarily through the use of swaps linked to the CPI. The CPI is a measure that examines the weighted average of prices of a basket of consumer goods and services, and measures changes in the purchasing power of the U.S. dollar and the rate of inflation. CPI swaps will not mitigate inflation risk regarding distributions made by the Fund itself.

By entering into a CPI swap, the Fund effectively turns the inflation component of the bonds held by the Fund or the Underlying Fund from fixed rates into floating rates. The Fund will lose money on the CPI swap and underperform if inflation is lower than the expected rate being hedged. The Fund will benefit from a CPI swap if actual inflation (as measured by the CPI) during the time period in which the Fund holds the swap is the same or greater than the level of inflation expected for that period. However, if actual inflation (as measured by the CPI) is less than the rate of inflation expected for that period, the Fund generally will lose money on the CPI

swap and underperform the Underlying Fund as a result of having entered into the CPI swap.

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 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. The historically low interest rate environment heightens the risks associated with rising interest rates.

In order to hedge the risk of interest rate increases due to inflation, the Fund will take positions in inflation hedging instruments. As a result, when the rate of inflation does not increase or when interest rates increase or decrease inversely to changes in the rate of inflation, the Fund will underperform the Underlying Fund. There is no guarantee that the Fund or Underlying Fund will have positive performance even in environments of sharply rising inflation.

S-7

---

 

There is no guarantee that the Fund or Underlying Fund will be able to successfully mitigate inflation risk or that bond values and interest rates will match changes in inflation rates.

Interest Rate Swap Risk. Interest rate swaps are subject to risks applicable to swaps generally, including the risk that a counterparty fails to meet its obligations and the risk that the Fund is not able to liquidate such swap in a timely manner or at all, which could result in losses to the Fund. Because the Fund will invest in swaps that are subject to central clearing, these swaps are subject to the risk that a central clearinghouse will go into bankruptcy or become non-operational, and sometimes involve increased transaction costs. Counterparties to OTC swaps are not subject to these risks. An interest rate swap may fail to perform as intended and may not offset adverse changes in interest rates fully or at all. An interest rate swap may also reduce the Fund’s gains due to favorable changes in interest rates and result in losses to the Fund. Counterparties to interest rate swaps are subject to manipulation in the marketplace of the reference benchmark rate, which may affect the utility of the swap as a hedge.

Investment in the Underlying Fund Risk. The Fund expects to invest a substantial portion of its assets in the Underlying Fund, so the Fund’s investment performance is likely to be directly related to the performance of the Underlying Fund, adjusted for the impact of changes in the rate of inflation. The Fund’s NAV will change with changes in the value of the Underlying Fund and other securities and instruments 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 Fund.

As the Fund’s allocations to the Underlying Fund change from time to time, or to the extent that the expense ratio of the Underlying Fund changes, the weighted average operating expenses borne by the Fund may increase or decrease.

Through its investment in the Underlying Fund, the Fund is exposed to Management Risk, Market Risk, and Market Trading Risk, among other risks.

Issuer Risk. The performance of the Fund depends on the performance of individual instruments to which the Fund or the Underlying Fund has exposure.The Fund may be adversely affected if an issuer of underlying securities held by the Fund or the Underlying Fund is unable or unwilling to repay principal or interest when due. Changes in the financial condition or credit rating of an issuer of those securities or counterparty on other instruments may cause the value of the securities or instruments to decline.

Management Risk. The Fund is subject to management risk, which is the risk that the investment process, techniques and risk analyses applied by BFA will not produce the desired results, and that securities selected by BFA may underperform the market or any relevant benchmark. In addition, legislative, regulatory, or tax developments may affect the investment techniques available to BFA in connection with managing the Fund and may also adversely affect the ability of the Fund to achieve its investment objective.

S-8

---

 

Market Risk. The Fund and the Underlying 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, the spread of infectious illness or other public health issue, recessions, 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 net asset value.

Market Trading Risk. The Fund and the Underlying Fund 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. Unlike some ETFs that track specific indexes, the Fund does not seek to replicate the performance of a specified index. Index-based ETFs have generally traded at prices that closely correspond to NAV. However, ETFs that do not seek to replicate the performance of a specified index have a limited trading history and, therefore, there can be no assurance as to whether, and/or the extent to which an arbitrage mechanism will develop. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Money Market Instruments Risk. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund's assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objective. An investment in a money market fund is not insured or

guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any other government agency. It is possible to lose money by investing in a money market fund. Money market funds other than government money market funds or retail money market funds “float” their NAV instead of using a stable $1.00 per share price.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund's performance may depend on the performance of a small number of issuers.

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.

Operational Risk. The Fund and the Underlying Fund 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 or the Underlying Fund's service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund, the Underlying Fund and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be

S-9

---

 

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 or the Underlying 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.

Privately Issued Securities Risk. The Fund or the Underlying Fund may invest in privately issued securities, including those that are normally purchased pursuant to Rule 144A or Regulation S promulgated under the Securities Act of 1933, as amended (“1933 Act”). Privately issued securities are securities that have not been registered under the 1933 Act and as a result may be subject to legal restrictions on resale. Privately issued securities are generally not traded on established markets. As a result of the absence of a public trading market, privately issued securities may be deemed to be illiquid investments, may be more difficult to value than publicly traded securities and may be subject to wide fluctuations in value. Delay or difficulty in selling such securities may result in a loss to the Fund.

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 Fund has exposure.

Risk of Swap Agreements. A swap is a two-party contract that generally obligates each counterparty to exchange periodic payments based on a pre-determined underlying investment

or notional amount and to exchange collateral to secure the obligations of each counterparty. Swaps may be leveraged and are subject to counterparty risk, credit risk and pricing risk. Swaps may be subject to illiquidity risk, and it may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

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

Small Fund Risk. When the Fund’s size is small, the Fund may experience low trading volume and wide bid/ask spreads. In addition, the Fund may face the risk of being delisted if the Fund does not meet certain conditions of the listing exchange. Any resulting liquidation of the Fund could cause the Fund to incur elevated transaction costs for the Fund and negative tax consequences for its shareholders.

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount

S-10

---

 

of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. Income from swaps is generally taxable. In addition, the tax treatment of certain derivatives, such as swaps, is unsettled and may be subject to future legislation, regulation or administrative pronouncements issued by the U.S. Internal Revenue Service (“IRS”).

Valuation Risk. The price the Fund or the Underlying Fund could receive upon the sale of a security or unwind of a financial instrument or other asset may differ from the Fund's or the Underlying Fund's valuation of the security or other asset, particularly for securities or other

instruments 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 instruments in the Fund's or the 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 the Underlying Fund's shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund or the 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 Fund or the Underlying Fund not fair-valued securities or used a different valuation methodology. The Fund’s or the Underlying Fund's 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. James Mauro and Scott Radell (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Mauro and Mr. Radell have been Portfolio Managers of the Fund since 2018.

Purchase and Sale of Fund Shares

The Fund is an ETF. Individual shares of the Fund are listed on a national securities exchange. Most investors will buy and sell shares of the Fund through a broker-dealer. The price of Fund shares is based on market price, and 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). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to Authorized Participants who have entered into agreements with the Fund's distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

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.
