The BondBloxx Bloomberg Six Month Target Duration US Treasury ETF (the “Fund”) seeks to track the investment results of an index composed of U.S. Treasury securities with a duration between 1 and 12 months.

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund.

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

Annual Fund Operating Expenses

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

The Fund is non-diversified and seeks to track the investment results of the Bloomberg US Treasury 6 Month Duration Index (the “Index”). The Index is comprised of certain U.S. Treasury bills that are included in the Bloomberg US Treasury Bill Index (the “Underlying Index”). The Index is constructed using two underlying “duration buckets” of U.S. Treasury bills included in the Underlying Index that are weighted by market capitalization of their component securities and then blended according to the weighting required to match the 6 month target duration of the Index at the monthly rebalancing date. Securities in the Index and the Underlying Index are updated on the last business day of each calendar month.

The Index and the Underlying Index are sponsored by Bloomberg Index Services Limited (the “Index Provider”), which is not affiliated with the Fund or BIM. The Index Provider determines the composition of the Index and the Underlying Index, relative weightings of the securities in the Index and the Underlying Index and publishes information regarding the respective market value of the Index and the Underlying Index. See “More Information About the Funds -- Index Construction” for more information about the adjustment formula. There is no limit to the number of issues in the Index and the Underlying Index, but as of December 31, 2022, the Index and the Underlying Index each included approximately 42 constituents. Because the Index and the Underlying Index are reconstituted and rebalanced monthly, the respective components of the Index and the Underlying Index are likely to change over time.

As of December 31, 2022, the securities eligible for inclusion in the Index include U.S. Treasury bills with durations in the following two duration bucket ranges from the Underlying Index: 1 to 6 month duration securities and 6 to 12 month duration securities. The Underlying Index tracks the market for Treasury bills issued by the U.S. Government. For more information regarding the Index and the Underlying Index, see “More Information About the Funds — Index” below.

BIM uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “outperform” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing will eliminate the chance that the Fund will substantially outperform the 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.

BIM uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of bonds that collectively has an investment profile similar to that of the Index. The bonds selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and sector weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to those of the Index. The Fund may or may not hold all of the bonds in the Index. There may be instances in which BIM may choose to underweight or overweight a security in the Index, purchase securities not in the Index that BIM believes are appropriate to substitute for certain securities in the Index in seeking to replicate as closely as possible, before fees and expenses, the performance of the Index. The Fund may sell securities that are represented in the Index in anticipation of their removal from the Index or purchase securities not represented in the Index in anticipation of their addition to the Index.

Under normal circumstances, the Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in a portfolio of U.S. Treasury securities that collectively have an average duration of approximately 6 months, either directly or indirectly (e.g., through derivatives). The Fund may also invest up to 20% of its net assets in certain other U.S. Treasury obligations, U.S. Government obligations, U.S. agency securities, cash and cash equivalents, as well as in securities not included in its Index, but which BIM believes will help the Fund track its Index.

The Fund seeks to track the investment results (i.e., the total return) of the Index before fees and expenses of the Fund.

The Index is sponsored by the Index Provider, which is independent of the Fund and BIM. The Index Provider determines the composition and relative weightings of the bonds in the Index and publishes information regarding the market value of the Index.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities.

As with any investment, you could lose all or a substantial 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.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. Government may cause the value of the Fund’s U.S. Treasury obligations to decline.

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

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. Recently, inflation levels have been at their highest point in nearly 40 years, and the U.S. Federal Reserve has begun a campaign to raise certain benchmark interest rates in an effort to combat inflation. 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 risks associated with rising interest rates may be particularly acute in markets where the Federal Reserve Board is raising rates over an extended period.

Limited History of Operations Risk. The Fund is a new fund and has a limited history of operations for investors to evaluate.

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the shares of the Fund.

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

Inflation Risk. Inflation is a sustained rise in overall price levels. Moderate inflation is associated with economic growth, while high inflation can signal an overheated economy. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money (i.e., as inflation increases, the values of the Fund’s assets can decline). Inflation poses a “stealth” threat to investors because it reduces savings and investment returns. Central banks, such as the U.S. Federal Reserve, generally attempt to control inflation by regulating the pace of economic activity. They typically attempt to affect economic activity by raising and lowering short-term interest rates. At times, governments may attempt to manage inflation through fiscal policy, such as by raising taxes or reducing spending, thereby reducing economic activity; conversely, governments can attempt to combat deflation with tax cuts and increased spending designed to stimulate economic activity. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund shareholders. This risk is greater for fixed-income instruments with longer maturities.

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, the spread of infectious illness or other public health issues, recessions, the advent of significant inflation, 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.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares or the Fund’s underlying portfolio securities, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. Accordingly, if a shareholder purchases Fund shares at a time when the market price is at a premium to the NAV, or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Index. Errors in index data, index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Index to vary from its normal or expected composition. In addition, the Index Provider may be subject to business or regulatory changes that impair its ability to continue to operate the Index in its current form.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV or differences between the securities prices used to value the Index and those used by the Fund), transaction costs incurred by the Fund, securities lending earnings, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Index or the costs to the Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

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

Focused Investment Risk. To the extent the Fund invests predominantly in U.S. Treasury securities, its performance will be especially sensitive to developments that significantly affect those securities. In addition, the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a more diversified mix of sectors, sub-sectors, industries, asset classes, markets, regions, or countries. The Fund’s performance could also be affected if U.S. Treasury securities do not perform as expected. Alternatively, a lack of exposure to one or more other sectors, sub-sectors, industries, asset classes, markets, regions, or countries may adversely affect performance.

Passive Investment Risk. The Fund is not actively managed, and BIM generally does not attempt to take defensive positions under any market conditions, including declining markets or changing interest rate environments.

Income Risk. The Fund’s income may decline if interest rates fall. This decline in income can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Index are substituted, or the Fund otherwise needs to purchase additional bonds.

Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds in securities with lower interest rates, which would result in a decline in the Fund’s income, or in securities with greater risks or with other less favorable features.

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 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.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The Fund may be adversely affected if an issuer of underlying securities held by the 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 may cause the value of the securities to decline.

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 has exposure.

Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund’s NAV. Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.

Concentration Risk. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities. The Fund may be susceptible to an increased risk of loss due to adverse events that affect U.S. Treasury securities more than the market as a whole.

Non-Diversification Risk. The Fund is classified as a “non-diversified” fund under the Investment Company Act of 1940, as amended. Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a “diversified” fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is subject to a higher degree of risk associated with and developments affecting that issuer than a fund that invests more widely.

Authorized Participant Concentration Risk. Only an Authorized Participant (as defined in the Creations and Redemptions section of this Prospectus) may engage in creation or redemption transactions directly with the Fund, and Authorized Participants are not 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 or unwilling to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is willing or able to step forward to create or redeem, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Management Risk. Because BIM uses a representative sampling indexing strategy, the Fund may not be able to fully replicate the Index and may hold securities not included in the Index. As a result, the Fund is subject to the risk that BIM’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, Authorized Participants, market makers, counterparties or other third-parties, failed or inadequate processes and computer, technology or systems failures. The Fund and BIM seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset and from the value used by the Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the 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 not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by a lack of current market prices, technological issues or errors by pricing services or other third-party service providers.

Cybersecurity Risk. Failures or breaches of the electronic or computer systems of the Fund, the Fund’s adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own a substantial amount of Fund shares, or may invest in the Fund and hold its investment 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. These large redemptions may also force the Fund to sell portfolio securities 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 the Shares.

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.

The Fund commenced investment operations on September 13, 2022 and therefore has a limited performance history.

The BondBloxx Bloomberg One Year Target Duration US Treasury ETF (the “Fund”) seeks to track the investment results of an index composed of U.S. Treasury securities with a duration between 6 and 18 months.

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund.

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

Annual Fund Operating Expenses

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

The Fund is non-diversified and seeks to track the investment results of the Bloomberg US Treasury 1 Year Duration Index (the “Index”). The Index is comprised of certain U.S. Treasury notes and bonds that are included in the Bloomberg US Short Treasury Index and the Bloomberg US Treasury Index (each an “Underlying Index”). The Index is constructed using two underlying “duration buckets” of U.S. Treasury notes and bonds included in each Underlying Index that are weighted by market capitalization of their component securities and then blended according to the weighting required to match the 1 year target duration of the Index at the monthly rebalancing date. Securities in the Index and each Underlying Index are updated on the last business day of each calendar month.

The Index and each Underlying Index are sponsored by Bloomberg Index Services Limited (the “Index Provider”), which is not affiliated with the Fund or BIM. The Index Provider determines the composition of the Index and each Underlying Index, relative weightings of the securities in the Index and each Underlying Index and publishes information regarding the respective market value of the Index and each Underlying Index. See “More Information About the Funds -- Index Construction” for more information about the adjustment formula.

There is no limit to the number of issues in the Index and in each Underlying Index, but as of December 31, 2022, the Index included approximately 53 constituents, the Bloomberg US Short Treasury Index included approximately 92 constituents and the Bloomberg US Treasury Index included approximately 276 constituents. Because the Index and each Underlying Index are reconstituted and rebalanced monthly, the respective components of the Index and each Underlying Index are likely to change over time.

As of December 31, 2022, the securities eligible for inclusion in the Index include U.S. Treasury notes and bonds with durations in the following two duration bucket ranges from the respective Underlying Index: 6 to 12 month duration securities from the Bloomberg US Short Treasury Index and 12 to 18 month duration securities from the Bloomberg US Treasury Index. The Bloomberg US Short Treasury Index is a market value weighted index of U.S. Treasury bills, notes, and bonds under 1 year to maturity. The Bloomberg US Treasury Index includes a broad range of U.S. Treasury obligations with a remaining maturity of 1 year or more. No U.S. Treasury bills from the Bloomberg US Short Treasury Index are included in the Index. For more information regarding the Index and each Underlying Index, see “More Information About the Funds — Index” below.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities.

As with any investment, you could lose all or a substantial 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.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. Government may cause the value of the Fund’s U.S. Treasury obligations to decline.

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

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. Recently, inflation levels have been at their highest point in nearly 40 years, and the U.S. Federal Reserve has begun a campaign to raise certain benchmark interest rates in an effort to combat inflation 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 risks associated with rising interest rates may be particularly acute in markets where the Federal Reserve Board is raising rates over an extended period.

Limited History of Operations Risk. The Fund is a new fund and has a limited history of operations for investors to evaluate.

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the shares of the Fund.

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

Inflation Risk. Inflation is a sustained rise in overall price levels. Moderate inflation is associated with economic growth, while high inflation can signal an overheated economy. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money (i.e., as inflation increases, the values of the Fund’s assets can decline).

This risk is greater for fixed-income instruments with longer maturities.

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, the spread of infectious illness or other public health issues, recessions, the advent of significant inflation, 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.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares or the Fund’s underlying portfolio securities, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. Accordingly, if a shareholder purchases Fund shares at a time when the market price is at a premium to the NAV, or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Index. Errors in index data, index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Index to vary from its normal or expected composition. In addition, the Index Provider may be subject to business or regulatory changes that impair its ability to continue to operate the Index in its current form.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV or differences between the securities prices used to value the Index and those used by the Fund), transaction costs incurred by the Fund, securities lending earnings, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Index or the costs to the Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

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

Focused Investment Risk. To the extent the Fund invests predominantly in U.S. Treasury securities, its performance will be especially sensitive to developments that significantly affect those securities. In addition, the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a more diversified mix of sectors, sub-sectors, industries, asset classes, markets, regions, or countries. The Fund’s performance could also be affected if U.S. Treasury securities do not perform as expected. Alternatively, a lack of exposure to one or more other sectors, sub-sectors, industries, asset classes, markets, regions, or countries may adversely affect performance.

Passive Investment Risk. The Fund is not actively managed, and BIM generally does not attempt to take defensive positions under any market conditions, including declining markets or changing interest rate environments.

Income Risk. The Fund’s income may decline if interest rates fall. This decline in income can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Index are substituted, or the Fund otherwise needs to purchase additional bonds.

Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds in securities with lower interest rates, which would result in a decline in the Fund’s income, or in securities with greater risks or with other less favorable features.

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 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.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The Fund may be adversely affected if an issuer of underlying securities held by the 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 may cause the value of the securities to decline.

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 has exposure.

Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund’s NAV. Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.

Concentration Risk. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities. The Fund may be susceptible to an increased risk of loss due to adverse events that affect U.S. Treasury securities more than the market as a whole.

Non-Diversification Risk. The Fund is classified as a “non-diversified” fund under the Investment Company Act of 1940, as amended. Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a “diversified” fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is subject to a higher degree of risk associated with and developments affecting that issuer than a fund that invests more widely.

Authorized Participant Concentration Risk. Only an Authorized Participant (as defined in the Creations and Redemptions section of this Prospectus) may engage in creation or redemption transactions directly with the Fund, and Authorized Participants are not 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 or unwilling to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is willing or able to step forward to create or redeem, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Management Risk. Because BIM uses a representative sampling indexing strategy, the Fund may not be able to fully replicate the Index and may hold securities not included in the Index. As a result, the Fund is subject to the risk that BIM’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, Authorized Participants, market makers, counterparties or other third-parties, failed or inadequate processes and computer, technology or systems failures. The Fund and BIM seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset and from the value used by the Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the 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 not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by a lack of current market prices, technological issues or errors by pricing services or other third-party service providers.

Cybersecurity Risk. Failures or breaches of the electronic or computer systems of the Fund, the Fund’s adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own a substantial amount of Fund shares, or may invest in the Fund and hold its investment 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. These large redemptions may also force the Fund to sell portfolio securities 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 the Shares.

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.

The Fund commenced investment operations on September 13, 2022 and therefore has a limited performance history. Once the Fund has completed a full calendar year of operations this section will show how the Fund’s total return has varied from year-to-year, along with a broad-based market index for reference. Past performance (before and after taxes) is not an indication of future performance. Because the Fund has not commenced operations as of the date of this Prospectus, there is no past performance to return. Updated performance information, including the Fund’s current NAV, may be obtained by visiting our website at www.bondbloxxetf.com or by calling (800) 896-5089 (toll free).

The BondBloxx Bloomberg Two Year Target Duration US Treasury ETF (the “Fund”) seeks to track the investment results of an index composed of U.S. Treasury securities with a duration between 1 and 3 years.

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund.

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

Annual Fund Operating Expenses

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

The Fund is non-diversified and seeks to track the investment results of the Bloomberg US Treasury 2 Year Duration Index (the “Index”). The Index is comprised of certain U.S. Treasury notes and bonds that are included in the Bloomberg US Treasury Index (the “Underlying Index”). The Index is constructed using two underlying “duration buckets” of U.S. Treasury notes and bonds included in the Underlying Index that are weighted by market capitalization of their component securities and then blended according to the weighting required to match the 2 year target duration of the Index at the monthly rebalancing date. Securities in the Index and the Underlying Index are updated on the last business day of each calendar month.

The Index and the Underlying Index are sponsored by Bloomberg Index Services Limited (the “Index Provider”), which is not affiliated with the Fund or BIM. The Index Provider determines the composition of the Index and the Underlying Index, relative weightings of the securities in the Index and the Underlying Index and publishes information regarding the respective market value of the Index and the Underlying Index. See “More Information About the Funds -- Index Construction” for more information about the adjustment formula.

There is no limit to the number of issues in the Index and the Underlying Index, but as of December 31, 2022, the Index included approximately 98 constituents, and the Underlying Index included approximately 276 constituents. Because the Index and the Underlying Index are reconstituted and rebalanced monthly, the respective components of the Index and the Underlying Index are likely to change over time.

As of December 31, 2022, the securities eligible for inclusion in the Index include U.S. Treasury notes and bonds with durations in the following two duration bucket ranges from the Underlying Index: 1 to 2 year duration securities and 2 to 3 year duration securities. The Underlying Index includes a broad range of U.S. Treasury obligations with a remaining maturity of 1 year or more. For more information regarding the Index and the Underlying Index, see “More Information About the Funds — Index” below.

BIM uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “outperform” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing will eliminate the chance that the Fund will substantially outperform the 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.

BIM uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of bonds that collectively has an investment profile similar to that of the Index. The bonds selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and sector weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to those of the Index. The Fund may or may not hold all of the bonds in the Index. There may be instances in which BIM may choose to underweight or overweight a security in the Index, purchase securities not in the Index that BIM believes are appropriate to substitute for certain securities in the Index in seeking to replicate as closely as possible, before fees and expenses, the performance of the Index. The Fund may sell securities that are represented in the Index in anticipation of their removal from the Index or purchase securities not represented in the Index in anticipation of their addition to the Index.

Under normal circumstances, the Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in a portfolio of U.S. Treasury securities that collectively have an average duration of approximately 2 years, either directly or indirectly (e.g., through derivatives). The Fund may also invest up to 20% of its net assets in certain other U.S. Treasury obligations, U.S. Government obligations, U.S. agency securities, cash and cash equivalents, as well as in securities not included in its Index, but which BIM believes will help the Fund track its Index.

The Fund seeks to track the investment results (i.e., the total return) of the Index before fees and expenses of the Fund.

The Index is sponsored by the Index Provider, which is independent of the Fund and BIM. The Index Provider determines the composition and relative weightings of the bonds in the Index and publishes information regarding the market value of the Index.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities.

As with any investment, you could lose all or a substantial 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.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. Government may cause the value of the Fund’s U.S. Treasury obligations to decline.

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

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. Recently, inflation levels have been at their highest point in nearly 40 years, and the U.S. Federal Reserve has begun a campaign to raise certain benchmark interest rates in an effort to combat inflation. 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 risks associated with rising interest rates may be particularly acute in markets where the Federal Reserve Board is raising rates over an extended period.

Limited History of Operations Risk. The Fund is a new fund and has a limited history of operations for investors to evaluate.

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the shares of the Fund.

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

Inflation Risk. Inflation is a sustained rise in overall price levels. Moderate inflation is associated with economic growth, while high inflation can signal an overheated economy. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money (i.e., as inflation increases, the values of the Fund’s assets can decline). Inflation poses a “stealth” threat to investors because it reduces savings and investment returns. Central banks, such as the U.S. Federal Reserve, generally attempt to control inflation by regulating the pace of economic activity. They typically attempt to affect economic activity by raising and lowering short-term interest rates. At times, governments may attempt to manage inflation through fiscal policy, such as by raising taxes or reducing spending, thereby reducing economic activity; conversely, governments can attempt to combat deflation with tax cuts and increased spending designed to stimulate economic activity. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund shareholders. This risk is greater for fixed-income instruments with longer maturities.

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, the spread of infectious illness or other public health issues, recessions, the advent of significant inflation, 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.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares or the Fund’s underlying portfolio securities, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. Accordingly, if a shareholder purchases Fund shares at a time when the market price is at a premium to the NAV, or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Index. Errors in index data, index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Index to vary from its normal or expected composition. In addition, the Index Provider may be subject to business or regulatory changes that impair its ability to continue to operate the Index in its current form.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV or differences between the securities prices used to value the Index and those used by the Fund), transaction costs incurred by the Fund, securities lending earnings, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Index or the costs to the Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

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

Focused Investment Risk. To the extent the Fund invests predominantly in U.S. Treasury securities, its performance will be especially sensitive to developments that significantly affect those securities. In addition, the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a more diversified mix of sectors, sub-sectors, industries, asset classes, markets, regions, or countries. The Fund’s performance could also be affected if U.S. Treasury securities do not perform as expected. Alternatively, a lack of exposure to one or more other sectors, sub-sectors, industries, asset classes, markets, regions, or countries may adversely affect performance.

Passive Investment Risk. The Fund is not actively managed, and BIM generally does not attempt to take defensive positions under any market conditions, including declining markets or changing interest rate environments.

Income Risk. The Fund’s income may decline if interest rates fall. This decline in income can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Index are substituted, or the Fund otherwise needs to purchase additional bonds.

Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds in securities with lower interest rates, which would result in a decline in the Fund’s income, or in securities with greater risks or with other less favorable features.

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 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.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The Fund may be adversely affected if an issuer of underlying securities held by the 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 may cause the value of the securities to decline.

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 has exposure.

Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund’s NAV. Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.

Concentration Risk. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities. The Fund may be susceptible to an increased risk of loss due to adverse events that affect U.S. Treasury securities more than the market as a whole.

Non-Diversification Risk. The Fund is classified as a “non-diversified” fund under the Investment Company Act of 1940, as amended. Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a “diversified” fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is subject to a higher degree of risk associated with and developments affecting that issuer than a fund that invests more widely.

Authorized Participant Concentration Risk. Only an Authorized Participant (as defined in the Creations and Redemptions section of this Prospectus) may engage in creation or redemption transactions directly with the Fund, and Authorized Participants are not 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 or unwilling to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is willing or able to step forward to create or redeem, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Management Risk. Because BIM uses a representative sampling indexing strategy, the Fund may not be able to fully replicate the Index and may hold securities not included in the Index. As a result, the Fund is subject to the risk that BIM’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, Authorized Participants, market makers, counterparties or other third-parties, failed or inadequate processes and computer, technology or systems failures. The Fund and BIM seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset and from the value used by the Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the 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 not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by a lack of current market prices, technological issues or errors by pricing services or other third-party service providers.

Cybersecurity Risk. Failures or breaches of the electronic or computer systems of the Fund, the Fund’s adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own a substantial amount of Fund shares, or may invest in the Fund and hold its investment 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. These large redemptions may also force the Fund to sell portfolio securities 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 the Shares.

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.

The Fund commenced investment operations on September 13, 2022 and therefore has a limited performance history. Once the Fund has completed a full calendar year of operations this section will show how the Fund’s total return has varied from year-to-year, along with a broad-based market index for reference. Past performance (before and after taxes) is not an indication of future performance. Because the Fund has not commenced operations as of the date of this Prospectus, there is no past performance to return. Updated performance information, including the Fund’s current NAV, may be obtained by visiting our website at www.bondbloxxetf.com or by calling (800) 896-5089 (toll free).

The BondBloxx Bloomberg Three Year Target Duration US Treasury ETF (the “Fund”) seeks to track the investment results of an index composed of U.S. Treasury securities with a duration between 2 and 4 years.

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund.

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

Annual Fund Operating Expenses

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

The Fund is non-diversified and seeks to track the investment results of the Bloomberg US Treasury 3 Year Duration Index (the “Index”). The Index is comprised of certain U.S. Treasury notes and bonds that are included in the Bloomberg US Treasury Index (the “Underlying Index”). The Index is constructed using two underlying “duration buckets” of U.S. Treasury notes and bonds included in the Underlying Index that are weighted by market capitalization of their component securities and then blended according to the weighting required to match the 3 year target duration of the Index at the monthly rebalancing date. Securities in the Index and the Underlying Index are updated on the last business day of each calendar month.

The Index and the Underlying Index are sponsored by Bloomberg Index Services Limited (the “Index Provider”), which is not affiliated with the Fund or BIM. The Index Provider determines the composition of the Index and the Underlying Index, relative weightings of the securities in the Index and the Underlying Index and publishes information regarding the respective market value of the Index and the Underlying Index. See “More Information About the Funds -- Index Construction” for more information about the adjustment formula.

There is no limit to the number of issues in the Index and the Underlying Index, but as of December 31, 2022, the Index included approximately 77 constituents, and the Underlying Index included approximately 276 constituents. Because the Index and the Underlying Index are reconstituted and rebalanced monthly, the respective components of the Index and the Underlying Index are likely to change over time.

As of December 31, 2022, the securities eligible for inclusion in the Index include U.S. Treasury notes and bonds with durations in the following two duration bucket ranges from the Underlying Index: 2 to 3 year duration securities and 3 to 4 year duration securities. The Underlying Index includes a broad range of U.S. Treasury obligations with a remaining maturity of 1 year or more. For more information regarding the Index and the Underlying Index, see “More Information About the Funds — Index” below.

BIM uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “outperform” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing will eliminate the chance that the Fund will substantially outperform the 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.

BIM uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of bonds that collectively has an investment profile similar to that of the Index. The bonds selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and sector weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to those of the Index. The Fund may or may not hold all of the bonds in the Index. There may be instances in which BIM may choose to underweight or overweight a security in the Index, purchase securities not in the Index that BIM believes are appropriate to substitute for certain securities in the Index in seeking to replicate as closely as possible, before fees and expenses, the performance of the Index. The Fund may sell securities that are represented in the Index in anticipation of their removal from the Index or purchase securities not represented in the Index in anticipation of their addition to the Index.

Under normal circumstances, the Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in a portfolio of U.S. Treasury securities that collectively have an average duration of approximately 3 years, either directly or indirectly (e.g., through derivatives). The Fund may also invest up to 20% of its net assets in certain other U.S. Treasury obligations, U.S. Government obligations, U.S. agency securities, cash and cash equivalents, as well as in securities not included in its Index, but which BIM believes will help the Fund track its Index.

The Fund seeks to track the investment results (i.e., the total return) of the Index before fees and expenses of the Fund.

The Index is sponsored by the Index Provider, which is independent of the Fund and BIM. The Index Provider determines the composition and relative weightings of the bonds in the Index and publishes information regarding the market value of the Index.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities.

As with any investment, you could lose all or a substantial 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.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. Government may cause the value of the Fund’s U.S. Treasury obligations to decline.

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

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. Recently, inflation levels have been at their highest point in nearly 40 years, and the U.S. Federal Reserve has begun a campaign to raise certain benchmark interest rates in an effort to combat inflation. 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 risks associated with rising interest rates may be particularly acute in markets where the Federal Reserve Board is raising rates over an extended period.

Limited History of Operations Risk. The Fund is a new fund and has a limited history of operations for investors to evaluate.

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the shares of the Fund.

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

Inflation Risk. Inflation is a sustained rise in overall price levels. Moderate inflation is associated with economic growth, while high inflation can signal an overheated economy. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money (i.e., as inflation increases, the values of the Fund’s assets can decline). Inflation poses a “stealth” threat to investors because it reduces savings and investment returns. Central banks, such as the U.S. Federal Reserve, generally attempt to control inflation by regulating the pace of economic activity. They typically attempt to affect economic activity by raising and lowering short-term interest rates. At times, governments may attempt to manage inflation through fiscal policy, such as by raising taxes or reducing spending, thereby reducing economic activity; conversely, governments can attempt to combat deflation with tax cuts and increased spending designed to stimulate economic activity. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund shareholders. This risk is greater for fixed-income instruments with longer maturities.

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, the spread of infectious illness or other public health issues, recessions, the advent of significant inflation, 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.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares or the Fund’s underlying portfolio securities, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. Accordingly, if a shareholder purchases Fund shares at a time when the market price is at a premium to the NAV, or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Index. Errors in index data, index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Index to vary from its normal or expected composition. In addition, the Index Provider may be subject to business or regulatory changes that impair its ability to continue to operate the Index in its current form.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV or differences between the securities prices used to value the Index and those used by the Fund), transaction costs incurred by the Fund, securities lending earnings, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Index or the costs to the Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

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

Focused Investment Risk. To the extent the Fund invests predominantly in U.S. Treasury securities, its performance will be especially sensitive to developments that significantly affect those securities. In addition, the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a more diversified mix of sectors, sub-sectors, industries, asset classes, markets, regions, or countries. The Fund’s performance could also be affected if U.S. Treasury securities do not perform as expected. Alternatively, a lack of exposure to one or more other sectors, sub-sectors, industries, asset classes, markets, regions, or countries may adversely affect performance.

Passive Investment Risk. The Fund is not actively managed, and BIM generally does not attempt to take defensive positions under any market conditions, including declining markets or changing interest rate environments.

Income Risk. The Fund’s income may decline if interest rates fall. This decline in income can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Index are substituted, or the Fund otherwise needs to purchase additional bonds.

Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds in securities with lower interest rates, which would result in a decline in the Fund’s income, or in securities with greater risks or with other less favorable features.

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 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.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The Fund may be adversely affected if an issuer of underlying securities held by the 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 may cause the value of the securities to decline

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 has exposure.

Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund’s NAV. Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.

Concentration Risk. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities. The Fund may be susceptible to an increased risk of loss due to adverse events that affect U.S. Treasury securities more than the market as a whole.

Non-Diversification Risk. The Fund is classified as a “non-diversified” fund under the Investment Company Act of 1940, as amended. Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a “diversified” fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is subject to a higher degree of risk associated with and developments affecting that issuer than a fund that invests more widely.

Authorized Participant Concentration Risk. Only an Authorized Participant (as defined in the Creations and Redemptions section of this Prospectus) may engage in creation or redemption transactions directly with the Fund, and Authorized Participants are not 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 or unwilling to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is willing or able to step forward to create or redeem, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Management Risk. Because BIM uses a representative sampling indexing strategy, the Fund may not be able to fully replicate the Index and may hold securities not included in the Index. As a result, the Fund is subject to the risk that BIM’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, Authorized Participants, market makers, counterparties or other third-parties, failed or inadequate processes and computer, technology or systems failures. The Fund and BIM seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset and from the value used by the Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the 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 not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by a lack of current market prices, technological issues or errors by pricing services or other third-party service providers.

Cybersecurity Risk. Failures or breaches of the electronic or computer systems of the Fund, the Fund’s adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own a substantial amount of Fund shares, or may invest in the Fund and hold its investment 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. These large redemptions may also force the Fund to sell portfolio securities 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 the Shares.

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.

The Fund commenced investment operations on September 13, 2022 and therefore has a limited performance history. Once the Fund has completed a full calendar year of operations this section will show how the Fund’s total return has varied from year-to-year, along with a broad-based market index for reference. Past performance (before and after taxes) is not an indication of future performance. Because the Fund has not commenced operations as of the date of this Prospectus, there is no past performance to return. Updated performance information, including the Fund’s current NAV, may be obtained by visiting our website at www.bondbloxxetf.com or by calling (800) 896-5089 (toll free).

The BondBloxx Bloomberg Five Year Target Duration US Treasury ETF (the “Fund”) seeks to track the investment results of an index composed of U.S. Treasury securities with a duration between 4 and 6 years.

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund.

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

Annual Fund Operating Expenses

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

The Fund is non-diversified and seeks to track the investment results of the Bloomberg US Treasury 5 Year Duration Index (the “Index”). The Index is comprised of certain U.S. Treasury notes and bonds that are included in the Bloomberg US Treasury Index (the “Underlying Index”). The Index is constructed using two underlying “duration buckets” of U.S. Treasury notes and bonds included in the Underlying Index that are weighted by market capitalization of their component securities and then blended according to the weighting required to match the 5 year target duration of the Index at the monthly rebalancing date. Securities in the Index and the Underlying Index are updated on the last business day of each calendar month.

The Index and the Underlying Index are sponsored by Bloomberg Index Services Limited (the “Index Provider”), which is not affiliated with the Fund or BIM. The Index Provider determines the composition of the Index and the Underlying Index, relative weightings of the securities in the Index and the Underlying Index and publishes information regarding the respective market value of the Index and the Underlying Index. See “More Information About the Funds -- Index Construction” for more information about the adjustment formula.

There is no limit to the number of issues in the Index and the Underlying Index, but as of December 31, 2022, the Index included approximately 56 constituents, and the Underlying Index included approximately 276 constituents. Because the Index and the Underlying Index are reconstituted and rebalanced monthly, the respective components of the Index and the Underlying Index are likely to change over time.

As of December 31, 2022, the securities eligible for inclusion in the Index include U.S. Treasury notes and bonds with durations in the following two duration bucket ranges from the Underlying Index: 4 to 5 year duration securities and 5 to 6 year duration securities. The Underlying Index includes a broad range of U.S. Treasury obligations with a remaining maturity of 1 year or more. For more information regarding the Index and the Underlying Index, see “More Information About the Funds — Index” below.

BIM uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “outperform” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing will eliminate the chance that the Fund will substantially outperform the 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.

BIM uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of bonds that collectively has an investment profile similar to that of the Index. The bonds selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and sector weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to those of the Index. The Fund may or may not hold all of the bonds in the Index. There may be instances in which BIM may choose to underweight or overweight a security in the Index, purchase securities not in the Index that BIM believes are appropriate to substitute for certain securities in the Index in seeking to replicate as closely as possible, before fees and expenses, the performance of the Index. The Fund may sell securities that are represented in the Index in anticipation of their removal from the Index or purchase securities not represented in the Index in anticipation of their addition to the Index.

Under normal circumstances, the Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in a portfolio of U.S. Treasury securities that collectively have an average duration of approximately 5 years, either directly or indirectly (e.g., through derivatives). The Fund may also invest up to 20% of its net assets in certain other U.S. Treasury obligations, U.S. Government obligations, U.S. agency securities, cash and cash equivalents, as well as in securities not included in its Index, but which BIM believes will help the Fund track its Index.

The Fund seeks to track the investment results (i.e., the total return) of the Index before fees and expenses of the Fund.

The Index is sponsored by the Index Provider, which is independent of the Fund and BIM. The Index Provider determines the composition and relative weightings of the bonds in the Index and publishes information regarding the market value of the Index.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities.

As with any investment, you could lose all or a substantial 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.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. Government may cause the value of the Fund’s U.S. Treasury obligations to decline.

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

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. Recently, inflation levels have been at their highest point in nearly 40 years, and the U.S. Federal Reserve has begun a campaign to raise certain benchmark interest rates in an effort to combat inflation. 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 risks associated with rising interest rates may be particularly acute in markets where the Federal Reserve Board is raising rates over an extended period.

Limited History of Operations Risk. The Fund is a new fund and has a limited history of operations for investors to evaluate.

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the shares of the Fund.

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

Inflation Risk. Inflation is a sustained rise in overall price levels. Moderate inflation is associated with economic growth, while high inflation can signal an overheated economy. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money (i.e., as inflation increases, the values of the Fund’s assets can decline). Inflation poses a “stealth” threat to investors because it reduces savings and investment returns. Central banks, such as the U.S. Federal Reserve, generally attempt to control inflation by regulating the pace of economic activity. They typically attempt to affect economic activity by raising and lowering short-term interest rates. At times, governments may attempt to manage inflation through fiscal policy, such as by raising taxes or reducing spending, thereby reducing economic activity; conversely, governments can attempt to combat deflation with tax cuts and increased spending designed to stimulate economic activity. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund shareholders. This risk is greater for fixed-income instruments with longer maturities.

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, the spread of infectious illness or other public health issues, recessions, the advent of significant inflation, 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.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares or the Fund’s underlying portfolio securities, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. Accordingly, if a shareholder purchases Fund shares at a time when the market price is at a premium to the NAV, or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Index. Errors in index data, index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Index to vary from its normal or expected composition. In addition, the Index Provider may be subject to business or regulatory changes that impair its ability to continue to operate the Index in its current form.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV or differences between the securities prices used to value the Index and those used by the Fund), transaction costs incurred by the Fund, securities lending earnings, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Index or the costs to the Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

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

Focused Investment Risk. To the extent the Fund invests predominantly in U.S. Treasury securities, its performance will be especially sensitive to developments that significantly affect those securities. In addition, the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a more diversified mix of sectors, sub-sectors, industries, asset classes, markets, regions, or countries. The Fund’s performance could also be affected if U.S. Treasury securities do not perform as expected. Alternatively, a lack of exposure to one or more other sectors, sub-sectors, industries, asset classes, markets, regions, or countries may adversely affect performance.

Passive Investment Risk. The Fund is not actively managed, and BIM generally does not attempt to take defensive positions under any market conditions, including declining markets or changing interest rate environments.

Income Risk. The Fund’s income may decline if interest rates fall. This decline in income can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Index are substituted, or the Fund otherwise needs to purchase additional bonds.

Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds in securities with lower interest rates, which would result in a decline in the Fund’s income, or in securities with greater risks or with other less favorable features.

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 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.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The Fund may be adversely affected if an issuer of underlying securities held by the 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 may cause the value of the securities to decline.

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 has exposure.

Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund’s NAV. Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.

Concentration Risk. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities. The Fund may be susceptible to an increased risk of loss due to adverse events that affect U.S. Treasury securities more than the market as a whole.

Non-Diversification Risk. The Fund is classified as a “non-diversified” fund under the Investment Company Act of 1940, as amended. Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a “diversified” fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is subject to a higher degree of risk associated with and developments affecting that issuer than a fund that invests more widely.

Authorized Participant Concentration Risk. Only an Authorized Participant (as defined in the Creations and Redemptions section of this Prospectus) may engage in creation or redemption transactions directly with the Fund, and Authorized Participants are not 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 or unwilling to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is willing or able to step forward to create or redeem, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Management Risk. Because BIM uses a representative sampling indexing strategy, the Fund may not be able to fully replicate the Index and may hold securities not included in the Index. As a result, the Fund is subject to the risk that BIM’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, Authorized Participants, market makers, counterparties or other third-parties, failed or inadequate processes and computer, technology or systems failures. The Fund and BIM seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset and from the value used by the Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the 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 not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by a lack of current market prices, technological issues or errors by pricing services or other third-party service providers.

Cybersecurity Risk. Failures or breaches of the electronic or computer systems of the Fund, the Fund’s adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own a substantial amount of Fund shares, or may invest in the Fund and hold its investment 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. These large redemptions may also force the Fund to sell portfolio securities 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 the Shares.

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.

The Fund commenced investment operations on September 13, 2022 and therefore has a limited performance history. Once the Fund has completed a full calendar year of operations, this section will show how the Fund’s total return has varied from year-to-year, along with a broad-based market index for reference. Past performance (before and after taxes) is not an indication of future performance. Because the Fund has not commenced operations as of the date of this prospectus, there is no past performance to return. Updated performance information, including the Fund’s current NAV, may be obtained by visiting our website at www.bondbloxxetf.com or by calling (800) 896-5089 (toll free).

The BondBloxx Bloomberg Seven Year Target Duration US Treasury ETF (the “Fund”) seeks to track the investment results of an index composed of U.S. Treasury securities with a duration between 5 and 9 years.

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund.

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

Annual Fund Operating Expenses

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

The Fund is non-diversified and seeks to track the investment results of the Bloomberg US Treasury 7 Year Duration Index (the “Index”). The Index is comprised of certain U.S. Treasury notes and bonds that are included in the Bloomberg US Treasury Index (the “Underlying Index”). The Index is constructed using two underlying “duration buckets” of U.S. Treasury notes and bonds included in the Underlying Index that are weighted by market capitalization of their component securities and then blended according to the weighting required to match the 7 year target duration of the Index at the monthly rebalancing date. Securities in the Index and the Underlying Index are updated on the last business day of each calendar month.

The Index and the Underlying Index are sponsored by Bloomberg Index Services Limited (the “Index Provider”), which is not affiliated with the Fund or BIM. The Index Provider determines the composition of the Index and the Underlying Index, relative weightings of the securities in the Index and the Underlying Index and publishes information regarding the respective market value of the Index and the Underlying Index. See “More Information About the Funds -- Index Construction” for more information about the adjustment formula.

There is no limit to the number of issues in the Index and the Underlying Index, but as of December 31, 2022, the Index included approximately 43 constituents, and the Underlying Index included approximately 276 constituents. Because the Index and the Underlying Index are reconstituted and rebalanced monthly, the respective components of the Index and the Underlying Index are likely to change over time.

As of December 31, 2022, the securities eligible for inclusion in the Index include U.S. Treasury notes and bonds with durations in the following two duration bucket ranges from the Underlying Index: 5 to 7 year duration securities and 7 to 9 year duration securities. The Underlying Index includes a broad range of U.S. Treasury obligations with a remaining maturity of 1 year or more. For more information regarding the Index and the Underlying Index, see “More Information About the Funds — Index” below.

BIM uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “outperform” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing will eliminate the chance that the Fund will substantially outperform the 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.

BIM uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of bonds that collectively has an investment profile similar to that of the Index. The bonds selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and sector weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to those of the Index. The Fund may or may not hold all of the bonds in the Index. There may be instances in which BIM may choose to underweight or overweight a security in the Index, purchase securities not in the Index that BIM believes are appropriate to substitute for certain securities in the Index in seeking to replicate as closely as possible, before fees and expenses, the performance of the Index. The Fund may sell securities that are represented in the Index in anticipation of their removal from the Index or purchase securities not represented in the Index in anticipation of their addition to the Index.

Under normal circumstances, the Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in a portfolio of U.S. Treasury securities that collectively have an average duration of approximately 7 years, either directly or indirectly (e.g., through derivatives). The Fund may also invest up to 20% of its net assets in certain other U.S. Treasury obligations, U.S. Government obligations, U.S. agency securities, cash and cash equivalents, as well as in securities not included in its Index, but which BIM believes will help the Fund track its Index.

The Fund seeks to track the investment results (i.e., the total return) of the Index before fees and expenses of the Fund.

The Index is sponsored by the Index Provider, which is independent of the Fund and BIM. The Index Provider determines the composition and relative weightings of the bonds in the Index and publishes information regarding the market value of the Index.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities.

As with any investment, you could lose all or a substantial 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.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. Government may cause the value of the Fund’s U.S. Treasury obligations to decline.

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

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. Recently, inflation levels have been at their highest point in nearly 40 years, and the U.S. Federal Reserve has begun a campaign to raise certain benchmark interest rates in an effort to combat inflation. 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 risks associated with rising interest rates may be particularly acute in markets where the Federal Reserve Board is raising rates over an extended period.

Limited History of Operations Risk. The Fund is a new fund and has a limited history of operations for investors to evaluate.

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the shares of the Fund.

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

Inflation Risk. Inflation is a sustained rise in overall price levels. Moderate inflation is associated with economic growth, while high inflation can signal an overheated economy. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money (i.e., as inflation increases, the values of the Fund’s assets can decline). Inflation poses a “stealth” threat to investors because it reduces savings and investment returns. Central banks, such as the U.S. Federal Reserve, generally attempt to control inflation by regulating the pace of economic activity. They typically attempt to affect economic activity by raising and lowering short-term interest rates. At times, governments may attempt to manage inflation through fiscal policy, such as by raising taxes or reducing spending, thereby reducing economic activity; conversely, governments can attempt to combat deflation with tax cuts and increased spending designed to stimulate economic activity. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund shareholders. This risk is greater for fixed-income instruments with longer maturities.

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, the spread of infectious illness or other public health issues, recessions, the advent of significant inflation, 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.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares or the Fund’s underlying portfolio securities, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. Accordingly, if a shareholder purchases Fund shares at a time when the market price is at a premium to the NAV, or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Index. Errors in index data, index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Index to vary from its normal or expected composition. In addition, the Index Provider may be subject to business or regulatory changes that impair its ability to continue to operate the Index in its current form.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV or differences between the securities prices used to value the Index and those used by the Fund), transaction costs incurred by the Fund, securities lending earnings, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Index or the costs to the Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

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

Focused Investment Risk. To the extent the Fund invests predominantly in U.S. Treasury securities, its performance will be especially sensitive to developments that significantly affect those securities. In addition, the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a more diversified mix of sectors, sub-sectors, industries, asset classes, markets, regions, or countries. The Fund’s performance could also be affected if U.S. Treasury securities do not perform as expected. Alternatively, a lack of exposure to one or more other sectors, sub-sectors, industries, asset classes, markets, regions, or countries may adversely affect performance.

Passive Investment Risk. The Fund is not actively managed, and BIM generally does not attempt to take defensive positions under any market conditions, including declining markets or changing interest rate environments.

Income Risk. The Fund’s income may decline if interest rates fall. This decline in income can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Index are substituted, or the Fund otherwise needs to purchase additional bonds.

Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds in securities with lower interest rates, which would result in a decline in the Fund’s income, or in securities with greater risks or with other less favorable features.

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 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.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The Fund may be adversely affected if an issuer of underlying securities held by the 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 may cause the value of the securities to decline.

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 has exposure.

Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund’s NAV. Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.

Concentration Risk. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities. The Fund may be susceptible to an increased risk of loss due to adverse events that affect U.S. Treasury securities more than the market as a whole.

Non-Diversification Risk. The Fund is classified as a “non-diversified” fund under the Investment Company Act of 1940, as amended. Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a “diversified” fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is subject to a higher degree of risk associated with and developments affecting that issuer than a fund that invests more widely.

Authorized Participant Concentration Risk. Only an Authorized Participant (as defined in the Creations and Redemptions section of this Prospectus) may engage in creation or redemption transactions directly with the Fund, and Authorized Participants are not 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 or unwilling to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is willing or able to step forward to create or redeem, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Management Risk. Because BIM uses a representative sampling indexing strategy, the Fund may not be able to fully replicate the Index and may hold securities not included in the Index. As a result, the Fund is subject to the risk that BIM’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, Authorized Participants, market makers, counterparties or other third-parties, failed or inadequate processes and computer, technology or systems failures. The Fund and BIM seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset and from the value used by the Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the 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 not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by a lack of current market prices, technological issues or errors by pricing services or other third-party service providers.

Cybersecurity Risk. Failures or breaches of the electronic or computer systems of the Fund, the Fund’s adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own a substantial amount of Fund shares, or may invest in the Fund and hold its investment 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. These large redemptions may also force the Fund to sell portfolio securities 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 the Shares.

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.

The Fund commenced investment operations on September 13, 2022 and therefore has a limited performance history. Once the Fund has completed a full calendar year of operations, this section will show how the Fund’s total return has varied from year-to-year, along with a broad-based market index for reference. Past performance (before and after taxes) is not an indication of future performance. Because the Fund has not commenced operations as of the date of this Prospectus, there is no past performance to return. Updated performance information, including the Fund’s current NAV, may be obtained by visiting our website at www.bondbloxxetf.com or by calling (800) 896-5089 (toll free).

The BondBloxx Bloomberg Ten Year Target Duration US Treasury ETF (the “Fund”) seeks to track the investment results of an index composed of U.S. Treasury securities with a duration between 6 and 14 years.

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund.

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

Annual Fund Operating Expenses

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

The Fund is non-diversified and seeks to track the investment results of the Bloomberg US Treasury 10 Year Duration Index (the “Index”). The Index is comprised of certain U.S. Treasury notes and bonds that are included in the Bloomberg US Treasury Index (the “Underlying Index”). The Index is constructed using two underlying “duration buckets” of U.S. Treasury notes and bonds included in the Underlying Index that are weighted by market capitalization of their component securities and then blended according to the weighting required to match the 10 year target duration of the Index at the monthly rebalancing date. Securities in the Index and the Underlying Index are updated on the last business day of each calendar month.

The Index and the Underlying Index are sponsored by Bloomberg Index Services Limited (the “Index Provider”), which is not affiliated with the Fund or BIM. The Index Provider determines the composition of the Index and the Underlying Index, relative weightings of the securities in the Index and the Underlying Index and publishes information regarding the respective market value of the Index and the Underlying Index. See “More Information About the Funds -- Index Construction” for more information about the adjustment formula.

There is no limit to the number of issues in the Index and the Underlying Index, but as of December 31, 2022, the Index included approximately 36 constituents, and the Underlying Index included approximately 276 constituents. Because the Index and the Underlying Index are reconstituted and rebalanced monthly, the respective components of the Index and the Underlying Index are likely to change over time.

As of December 31, 2022, the securities eligible for inclusion in the Index include U.S. Treasury notes and bonds with durations in the following two duration bucket ranges from the Underlying Index: 6 to 10 year duration securities and 10 to 14 year duration securities. The Underlying Index includes a broad range of U.S. Treasury obligations with a remaining maturity of 1 year or more. For more information regarding the Index and the Underlying Index, see “More Information About the Funds — Index” below.

BIM uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “outperform” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing will eliminate the chance that the Fund will substantially outperform the 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.

BIM uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of bonds that collectively has an investment profile similar to that of the Index. The bonds selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and sector weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to those of the Index. The Fund may or may not hold all of the bonds in the Index. There may be instances in which BIM may choose to underweight or overweight a security in the Index, purchase securities not in the Index that BIM believes are appropriate to substitute for certain securities in the Index in seeking to replicate as closely as possible, before fees and expenses, the performance of the Index. The Fund may sell securities that are represented in the Index in anticipation of their removal from the Index or purchase securities not represented in the Index in anticipation of their addition to the Index.

Under normal circumstances, the Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in a portfolio of U.S. Treasury securities that collectively have an average duration of approximately 10 years, either directly or indirectly (e.g., through derivatives). The Fund may also invest up to 20% of its net assets in certain other U.S. Treasury obligations, U.S. Government obligations, U.S. agency securities, cash and cash equivalents, as well as in securities not included in its Index, but which BIM believes will help the Fund track its Index.

The Fund seeks to track the investment results (i.e., the total return) of the Index before fees and expenses of the Fund.

The Index is sponsored by the Index Provider, which is independent of the Fund and BIM. The Index Provider determines the composition and relative weightings of the bonds in the Index and publishes information regarding the market value of the Index.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities.

As with any investment, you could lose all or a substantial 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.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. Government may cause the value of the Fund’s U.S. Treasury obligations to decline.

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

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. Recently, inflation levels have been at their highest point in nearly 40 years, and the U.S. Federal Reserve has begun a campaign to raise certain benchmark interest rates in an effort to combat inflation. 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 risks associated with rising interest rates may be particularly acute in markets where the Federal Reserve Board is raising rates over an extended period.

Limited History of Operations Risk. The Fund is a new fund and has a limited history of operations for investors to evaluate.

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the shares of the Fund.

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

Inflation Risk. Inflation is a sustained rise in overall price levels. Moderate inflation is associated with economic growth, while high inflation can signal an overheated economy. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money (i.e., as inflation increases, the values of the Fund’s assets can decline). Inflation poses a “stealth” threat to investors because it reduces savings and investment returns. Central banks, such as the U.S. Federal Reserve, generally attempt to control inflation by regulating the pace of economic activity. They typically attempt to affect economic activity by raising and lowering short-term interest rates. At times, governments may attempt to manage inflation through fiscal policy, such as by raising taxes or reducing spending, thereby reducing economic activity; conversely, governments can attempt to combat deflation with tax cuts and increased spending designed to stimulate economic activity. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund shareholders. This risk is greater for fixed-income instruments with longer maturities.

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, the spread of infectious illness or other public health issues, recessions, the advent of significant inflation, 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.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares or the Fund’s underlying portfolio securities, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. Accordingly, if a shareholder purchases Fund shares at a time when the market price is at a premium to the NAV, or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Index. Errors in index data, index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Index to vary from its normal or expected composition. In addition, the Index Provider may be subject to business or regulatory changes that impair its ability to continue to operate the Index in its current form.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV or differences between the securities prices used to value the Index and those used by the Fund), transaction costs incurred by the Fund, securities lending earnings, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Index or the costs to the Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

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

Focused Investment Risk. To the extent the Fund invests predominantly in U.S. Treasury securities, its performance will be especially sensitive to developments that significantly affect those securities. In addition, the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a more diversified mix of sectors, sub-sectors, industries, asset classes, markets, regions, or countries. The Fund’s performance could also be affected if U.S. Treasury securities do not perform as expected. Alternatively, a lack of exposure to one or more other sectors, sub-sectors, industries, asset classes, markets, regions, or countries may adversely affect performance.

Passive Investment Risk. The Fund is not actively managed, and BIM generally does not attempt to take defensive positions under any market conditions, including declining markets or changing interest rate environments.

Income Risk. The Fund’s income may decline if interest rates fall. This decline in income can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Index are substituted, or the Fund otherwise needs to purchase additional bonds.

Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds in securities with lower interest rates, which would result in a decline in the Fund’s income, or in securities with greater risks or with other less favorable features.

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 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.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The Fund may be adversely affected if an issuer of underlying securities held by the 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 may cause the value of the securities to decline.

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 has exposure.

Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund’s NAV. Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.

Concentration Risk. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities. The Fund may be susceptible to an increased risk of loss due to adverse events that affect U.S. Treasury securities more than the market as a whole.

Non-Diversification Risk. The Fund is classified as a “non-diversified” fund under the Investment Company Act of 1940, as amended. Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a “diversified” fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is subject to a higher degree of risk associated with and developments affecting that issuer than a fund that invests more widely.

Authorized Participant Concentration Risk. Only an Authorized Participant (as defined in the Creations and Redemptions section of this Prospectus) may engage in creation or redemption transactions directly with the Fund, and Authorized Participants are not 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 or unwilling to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is willing or able to step forward to create or redeem, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Management Risk. Because BIM uses a representative sampling indexing strategy, the Fund may not be able to fully replicate the Index and may hold securities not included in the Index. As a result, the Fund is subject to the risk that BIM’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, Authorized Participants, market makers, counterparties or other third-parties, failed or inadequate processes and computer, technology or systems failures. The Fund and BIM seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset and from the value used by the Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the 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 not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by a lack of current market prices, technological issues or errors by pricing services or other third-party service providers.

Cybersecurity Risk. Failures or breaches of the electronic or computer systems of the Fund, the Fund’s adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own a substantial amount of Fund shares, or may invest in the Fund and hold its investment 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. These large redemptions may also force the Fund to sell portfolio securities 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 the Shares.

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.

The Fund commenced investment operations on September 13, 2022 and therefore has a limited performance history. Once the Fund has completed a full calendar year of operations this section will show how the Fund’s total return has varied from year-to-year, along with a broad-based market index for reference. Past performance (before and after taxes) is not an indication of future performance. Because the Fund has not commenced operations as of the date of this Prospectus, there is no past performance to return. Updated performance information, including the Fund’s current NAV, may be obtained by visiting our website at www.bondbloxxetf.com or by calling (800) 896-5089 (toll free).

The BondBloxx Bloomberg Twenty Year Target Duration US Treasury ETF (the “Fund”) seeks to track the investment results of an index composed of U.S. Treasury securities with a duration of 20 years.

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund.

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

Annual Fund Operating Expenses

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

The Fund is non-diversified and seeks to track the investment results of the Bloomberg US Treasury 20 Year Duration Index (the “Index”). The Index is comprised of certain U.S. Treasury notes and bonds that are included in the Bloomberg US Treasury Index (the “Underlying Index”), along with principal only U.S. Treasury STRIPS (as defined herein). The Index is constructed using two underlying buckets: one bucket of 16 to 20 year duration U.S. Treasury notes and bonds included in the Underlying Index, and one bucket of at least 20 year duration U.S. Treasury notes and bonds included in the Underlying Index along with principal only U.S. Treasury STRIPS. The buckets are weighted by market capitalization of their component securities and then blended according to the weighting required to match the 20 year target duration of the Index at the monthly rebalancing date. Securities in the Index and the Underlying Index are updated on the last business day of each calendar month.

The Index and the Underlying Index are sponsored by Bloomberg Index Services Limited (the “Index Provider”), which is not affiliated with the Fund or BIM. The Index Provider determines the composition of the Index and the Underlying Index, relative weightings of the securities in the Index and the Underlying Index and publishes information regarding the respective market value of the Index and the Underlying Index. See “More Information About the Funds -- Index Construction” for more information about the adjustment formula.

There is no limit to the number of issues in the Index and the Underlying Index, but as of December 31, 2022, the Index included approximately 68 constituents, and the Underlying Index included approximately 276 constituents. Because the Index and the Underlying Index are reconstituted and rebalanced monthly, the respective components of the Index and the Underlying Index are likely to change over time.

As of December 31, 2022, the securities eligible for inclusion in the Index include U.S. Treasury notes and bonds from the Underlying Index, along with U.S. Treasury STRIPS, in the following two buckets: 16 to 20 year duration securities from the Underlying Index and (2) at least 20 year duration securities from the Underlying Index, along with principal only U.S. Treasury STRIPS. The Underlying Index includes a broad range of U.S. Treasury obligations with a remaining maturity of 1 year or more. For more information regarding the Index and the Underlying Index, see “More Information About the Funds — Index” below.

BIM uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “outperform” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing will eliminate the chance that the Fund will substantially outperform the 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.

BIM uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of bonds that collectively has an investment profile similar to that of the Index. The bonds selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and sector weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to those of the Index. The Fund may or may not hold all of the bonds in the Index. There may be instances in which BIM may choose to underweight or overweight a security in the Index, purchase securities not in the Index that BIM believes are appropriate to substitute for certain securities in the Index in seeking to replicate as closely as possible, before fees and expenses, the performance of the Index. The Fund may sell securities that are represented in the Index in anticipation of their removal from the Index or purchase securities not represented in the Index in anticipation of their addition to the Index.

Under normal circumstances, the Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in a portfolio of U.S. Treasury securities that collectively have an average duration of approximately 20 years, either directly or indirectly (e.g., through derivatives). U.S. Treasury STRIPS are considered U.S. Treasury securities for purposes of the Fund’s investment policies and are backed by the full faith and credit of the U.S. government. The Fund may also invest up to 20% of its net assets in certain other U.S. Treasury obligations, U.S. Government obligations, U.S. agency securities, cash and cash equivalents, as well as in securities not included in its Index, but which BIM believes will help the Fund track its Index.

The Fund seeks to track the investment results (i.e., the total return) of the Index before fees and expenses of the Fund.

The Index is sponsored by the Index Provider, which is independent of the Fund and BIM. The Index Provider determines the composition and relative weightings of the bonds in the Index and publishes information regarding the market value of the Index.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities.

As with any investment, you could lose all or a substantial 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.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. Government may cause the value of the Fund’s U.S. Treasury obligations to decline.

U.S. Treasury obligations include separately traded interest and principal component parts of such obligations, known as Separately Traded Registered Interest and Principal Securities (“STRIPS”), which are transferable through the Federal book-entry system. STRIPS are sold as zero-coupon securities, which means that they are sold at a substantial discount and redeemed at face value at their maturity date without interim cash payments of interest or principal. This discount is accreted over the life of the security, and such accretion will constitute the income earned on the security for both accounting and tax purposes. Because of these features, such securities may be subject to greater interest rate volatility than interest paying U.S. Treasury obligations.

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

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. Recently, inflation levels have been at their highest point in nearly 40 years, and the U.S. Federal Reserve has begun a campaign to raise certain benchmark interest rates in an effort to combat inflation. 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 risks associated with rising interest rates may be particularly acute in markets where the Federal Reserve Board is raising rates over an extended period.

Limited History of Operations Risk. The Fund is a new fund and has a limited history of operations for investors to evaluate.

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the shares of the Fund.

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

Inflation Risk. Inflation is a sustained rise in overall price levels. Moderate inflation is associated with economic growth, while high inflation can signal an overheated economy. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money (i.e., as inflation increases, the values of the Fund’s assets can decline). Inflation poses a “stealth” threat to investors because it reduces savings and investment returns. Central banks, such as the U.S. Federal Reserve, generally attempt to control inflation by regulating the pace of economic activity. They typically attempt to affect economic activity by raising and lowering short-term interest rates. At times, governments may attempt to manage inflation through fiscal policy, such as by raising taxes or reducing spending, thereby reducing economic activity; conversely, governments can attempt to combat deflation with tax cuts and increased spending designed to stimulate economic activity. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund shareholders. This risk is greater for fixed-income instruments with longer maturities.

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, the spread of infectious illness or other public health issues, recessions, the advent of significant inflation, 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.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares or the Fund’s underlying portfolio securities, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. Accordingly, if a shareholder purchases Fund shares at a time when the market price is at a premium to the NAV, or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Index. Errors in index data, index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Index to vary from its normal or expected composition. In addition, the Index Provider may be subject to business or regulatory changes that impair its ability to continue to operate the Index in its current form.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV or differences between the securities prices used to value the Index and those used by the Fund), transaction costs incurred by the Fund, securities lending earnings, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Index or the costs to the Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not.

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

The Fund’s performance could also be affected if U.S. Treasury securities do not perform as expected. Alternatively, a lack of exposure to one or more other sectors, sub-sectors, industries, asset classes, markets, regions, or countries may adversely affect performance.

Passive Investment Risk. The Fund is not actively managed, and BIM generally does not attempt to take defensive positions under any market conditions, including declining markets or changing interest rate environments.

Income Risk. The Fund’s income may decline if interest rates fall. This decline in income can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Index are substituted, or the Fund otherwise needs to purchase additional bonds.

Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds in securities with lower interest rates, which would result in a decline in the Fund’s income, or in securities with greater risks or with other less favorable features.

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 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.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The Fund may be adversely affected if an issuer of underlying securities held by the 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 may cause the value of the securities to decline.

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 has exposure.

Infectious Illness Risk. A widespread outbreak of an infectious illness, such as the COVID-19 pandemic, may result in travel restrictions, disruption of healthcare services, prolonged quarantines, cancellations, supply chain disruptions, business closures, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic, social and political impacts. Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund’s NAV. Despite the development of vaccines, the duration of the COVID-19 pandemic and its effects cannot be predicted with certainty.

Concentration Risk. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in U.S Treasury securities. The Fund may be susceptible to an increased risk of loss due to adverse events that affect U.S. Treasury securities more than the market as a whole.

Non-Diversification Risk. The Fund is classified as a “non-diversified” fund under the Investment Company Act of 1940, as amended. Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a “diversified” fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is subject to a higher degree of risk associated with and developments affecting that issuer than a fund that invests more widely.

Authorized Participant Concentration Risk. Only an Authorized Participant (as defined in the Creations and Redemptions section of this Prospectus) may engage in creation or redemption transactions directly with the Fund, and Authorized Participants are not 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 or unwilling to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is willing or able to step forward to create or redeem, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Management Risk. Because BIM uses a representative sampling indexing strategy, the Fund may not be able to fully replicate the Index and may hold securities not included in the Index. As a result, the Fund is subject to the risk that BIM’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, Authorized Participants, market makers, counterparties or other third-parties, failed or inadequate processes and computer, technology or systems failures. The Fund and BIM seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset and from the value used by the Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the 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 not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by a lack of current market prices, technological issues or errors by pricing services or other third-party service providers.

Cybersecurity Risk. Failures or breaches of the electronic or computer systems of the Fund, the Fund’s adviser, distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own a substantial amount of Fund shares, or may invest in the Fund and hold its investment 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. These large redemptions may also force the Fund to sell portfolio securities 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 the Shares.

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.

The Fund commenced investment operations on September 13, 2022 and therefore has a limited performance history. Once the Fund has completed a full calendar year of operations this section will show how the Fund’s total return has varied from year-to-year, along with a broad-based market index for reference. Past performance (before and after taxes) is not an indication of future performance. Because the Fund has not commenced operations as of the date of this Prospectus, there is no past performance to return. Updated performance information, including the Fund’s current NAV, may be obtained by visiting our website at www.bondbloxxetf.com or by calling (800) 896-5089 (toll free).
