The Invesco BulletShares 2023 Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares® USD Corporate Bond 2023 Index (the “Underlying Index”).

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Example. This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. This example does not include brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

The Fund generally will invest at least 80% of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index.

The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Underlying Index seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2023 (collectively, “2023 Bonds”). Certain bonds in which the Fund may invest may contain embedded issuer call options. An embedded issuer call option means that the bond’s issuer has the right to redeem a bond prior to its designated maturity date. Accordingly, the effective maturity date of a bond reflects an assessment of when that bond is likely to be called by the issuer, or in the alternate, the bond’s stated maturity date (if it is not called by the issuer). With respect to establishing the effective maturity of a bond, the effective maturity is the actual year of maturity (i) if no embedded issuer call option exists for a bond; (ii) if a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call

price; and (iii) unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

2023 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance prior to the final maturing year of the Underlying Index. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective.

The following summarizes the principal risks of investing in the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may occur quickly and without advance warning following sudden market downturns or unexpected developments involving an issuer, and which may adversely affect the liquidity and value of the security.

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, foreign securities may have relatively low market liquidity, greater market volatility, decreased publicly available information, and less reliable financial information about issuers, and inconsistent and potentially less stringent accounting, auditing and financial reporting requirements and standards of practice, including recordkeeping standards, comparable to those applicable to domestic issuers. Foreign securities also are subject to the risks of expropriation, nationalization, political instability or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in foreign securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions and higher transactional costs.

Industry Concentration Risk. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its

investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or industry group may be out of favor and underperform other industries or the market as a whole.

Fluctuation of Yield and Liquidation Amount Risk. The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercises such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall.

Reinvestment Risk. Reinvestment risk is the risk that the Fund will not be able to reinvest income or principal at the same return it is currently earning. Reinvestment risk is greater during periods of declining interest rates, as prepayments often occur faster. It is related to call risk, since issuers of callable securities with high interest coupons may call their bonds before their maturity date. This may require the Fund to reinvest the proceeds at an earlier date, and it may be able to do so only at lower yields, thereby reducing its return.

Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price.

Declining Yield Risk. During the final year of the Fund's operations, as the bonds held by the Fund mature and the Fund's portfolio transitions to

cash and cash equivalents, the Fund's yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Issuer-Specific Changes Risk. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole.

Valuation Risk. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. In certain circumstances, market quotations may not be readily available for some Fund securities, and those securities may be fair valued. The value established for a security through fair valuation may be different from what would be produced if the security had been valued using market quotations. Fund securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuations in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a portfolio security for the value established for it at any time, and it is possible that the Fund would incur a loss because a security is sold at a discount to its established value.

Valuation Time Risk. Because foreign exchanges may be open on days when the Fund does not price its Shares, the value of the non-U.S. securities in the Fund’s portfolio may change on days when you will not be able to purchase or sell your Shares. As a result, trading spreads and the resulting premium or discount on the Shares may widen, and, therefore, increase the difference between the market price of the Shares and the NAV of such Shares.

Sampling Risk. The Fund's use of a representative sampling approach may result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development with respect to an issuer of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.

Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, and Shares may be more likely to trade at a premium or discount to the Fund's NAV and to face trading halts and/or delisting.

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, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the Adviser 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 these risks.

The bar chart below shows how the Fund has performed. The table below the bar chart shows the Fund’s average annual total returns (before and after taxes). The bar chart and table provide an indication of the risks of investing in the Fund by showing how the Fund’s total returns have varied from year to year and by showing how the Fund’s average annual total returns compared with a broad measure of market performance and an additional index with characteristics relevant to the Fund. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim BulletShares 2023 Corporate Bond ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on April 6, 2018. Accordingly, the performance information shown below for periods ending on or prior to April 6, 2018 is that of the Predecessor Fund.

If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price.

Declining Yield Risk. During the final year of the Fund's operations, as the bonds held by the Fund mature and the Fund's portfolio transitions to

cash and cash equivalents, the Fund's yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Issuer-Specific Changes Risk. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole.

Valuation Risk. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. In certain circumstances, market quotations may not be readily available for some Fund securities, and those securities may be fair valued. The value established for a security through fair valuation may be different from what would be produced if the security had been valued using market quotations. Fund securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuations in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a portfolio security for the value established for it at any time, and it is possible that the Fund would incur a loss because a security is sold at a discount to its established value.

Valuation Time Risk. Because foreign exchanges may be open on days when the Fund does not price its Shares, the value of the non-U.S. securities in the Fund’s portfolio may change on days when you will not be able to purchase or sell your Shares. As a result, trading spreads and the resulting premium or discount on the Shares may widen, and, therefore, increase the difference between the market price of the Shares and the NAV of such Shares.

Sampling Risk. The Fund's use of a representative sampling approach may result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development with respect to an issuer of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.

Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, and Shares may be more likely to trade at a premium or discount to the Fund's NAV and to face trading halts and/or delisting.

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, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the Adviser 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 these risks.

The bar chart below shows how the Fund has performed. The table below the bar chart shows the Fund’s average annual total returns (before and after taxes). The bar chart and table provide an indication of the risks of investing in the Fund by showing how the Fund’s total returns have varied from year to year and by showing how the Fund’s average annual total returns compared with a broad measure of market performance and an additional index with characteristics relevant to the Fund. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim BulletShares 2025 Corporate Bond ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated, after the close of business on April 6, 2018. Accordingly, the performance information shown below for periods ending on or prior to April 6, 2018 is that of the Predecessor Fund.

After-tax returns in the above table are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold Shares through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts.
