Innovator Emerging Markets Power Buffer ETF™- July

(NYSE Arca-EJUL)

February 28, 2022
as supplemented on July 1, 2022

Innovator Emerging Markets Power Buffer ETF™ - July (the "Fund") is a series of
Innovator ETFs Trust (the "Trust") and is an actively managed ETF.

The Fund will invest substantially all of its assets in FLexible EXchange® Options ("FLEX Options") on the iShares MSCI Emerging Markets ETF (the "Underlying ETF"). FLEX Options are customizable exchange-traded option contracts guaranteed for settlement by the Options Clearing Corporation. The Fund uses FLEX Options to employ a "defined outcome strategy." Defined outcome strategies seek to produce pre-determined investment outcomes based upon the performance of an underlying security or index. The pre-determined outcomes sought by the Fund, which include the buffer and cap discussed below ("Outcomes"), are based upon the performance of the Underlying ETF's share price over an approximately one-year period from July 1 through June 30 of the following year (the "Outcome Period"). The current Outcome Period is from July 1, 2022 through June 30, 2023. The Fund will not terminate after the conclusion of the Outcome Period. After the conclusion of the Outcome Period, another will begin. There is no guarantee that the Outcomes for an Outcome Period will be realized.

The Fund's strategy has been specifically designed to produce the Outcomes based upon the performance of the Underlying ETF's share price (or its "price return") over the duration of the Outcome Period. The Fund will not receive or benefit from any dividend payments made by the Underlying ETF. The Outcomes may only be realized by investors who hold shares of the Fund ("Shares") at the outset of the Outcome Period and continue to hold them until the conclusion of the Outcome Period. Investors that purchase Fund Shares after the Outcome Period has begun, or sell Fund Shares prior to the Outcome Period's conclusion, may experience investment returns very different from those that the Fund seeks to provide. The Fund will not receive or benefit from any dividend payments made by the Underlying ETF.

Fund shareholders are subject to an upside return cap (the "Cap") that represents the maximum percentage return an investor can achieve from an investment in Fund Shares over the duration of the Outcome Period. The Cap is set on the first day of the Outcome Period and is 19.07% prior to taking into account any fees or expenses charged to shareholders. When the Fund's annual Fund management fee of 0.89% of the Fund's average daily net assets is taken into account, the Cap is 18.18%. The Cap will be further reduced by any shareholder transaction fees and any extraordinary expenses incurred by the Fund. The Cap is likely to rise or fall from one Outcome Period to the next. Please note, if the Outcome Period has begun and the Fund has increased in value to a level near the Cap, an investor purchasing Fund Shares at that price has little or no ability to achieve gains but remains vulnerable to downside risks.

The Fund seeks to provide shareholders that hold Fund Shares for the entire Outcome Period with a buffer (the "Buffer") against the first 15% of Underlying ETF losses during the Outcome Period. "Power" denotes the Fund's objective to provide returns that are buffered by up to 15% if the Underlying ETF's share price experiences a loss during the course of the Outcome Period. The Fund's shareholders will bear all Underlying ETF losses exceeding 15% on a one-to-one basis. The Buffer is provided prior to taking into account annual Fund management fees, shareholder transaction fees and any extraordinary expenses incurred by the Fund. When the Fund's annual management fee equal to 0.89% of the Fund's daily net assets is taken into account, the net Buffer for the Outcome Period is 14.11%. The Buffer will be further reduced by any shareholder transaction fees and any extraordinary expenses incurred by the Fund. These fees and any expenses will have the effect of reducing the Buffer amount for Fund shareholders for an Outcome Period. If the Outcome Period has begun and the Fund has decreased in value beyond the pre-determined 15% Buffer, an investor purchasing Fund Shares at that price may not benefit from the Buffer. Similarly, if the Outcome Period has begun and the Fund has increased in value, an investor purchasing Fund Shares at that price may not benefit from the Buffer until the Fund's value has decreased to its value at the commencement of the Outcome Period. An investment in Fund Shares is only appropriate for shareholders willing to bear those losses.

The Fund's website, www.innovatoretfs.com/ejul, provides important Fund information (including, among other items, Outcome Period start and end dates and information relating to the Cap and Buffer), as well information relating to the potential outcomes of an investment in the Fund on a daily basis. If you are contemplating purchasing Shares, please visit the website. The Fund's strategy is designed to produce the Outcomes upon the expiration of its FLEX Options investments on the last day of the Outcome Period. It should not be expected that the Outcomes, including the net effect of the Fund's annual management fee on the Cap and Buffer, will be provided at any point prior to the last day of the Outcome Period. Investors considering purchasing Fund Shares after the Outcome Period has begun or selling Fund Shares prior to the end of the Outcome Period should visit the website to fully understand potential investment outcomes.

Although the Fund seeks to achieve its investment objective, there is no guarantee that it will do so. The returns that the Fund seeks to provide do not include the costs associated with purchasing Fund Shares and certain expenses incurred by the Fund. The Fund has characteristics unlike many other traditional investment products and may not be suitable for all investors.

The U.S. Securities and Exchange Commission ("SEC") has not approved or disapproved these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

Innovator Emerging Markets Power Buffer ETF™ - July

Investment Objective

The Fund seeks to provide investors with returns that match the price return of the iShares MSCI Emerging Markets ETF, up to the upside cap of 19.07% (prior to taking into account management fees and other fees) and 18.18% (after taking into account management fees) while providing a buffer against the first 15% (prior to taking into account management fees and other fees) and 14.11% (after taking into account management fees) of iShares MSCI Emerging Markets ETF losses, over the period from July 1, 2022 to June 30, 2023.

Fees and Expenses of the Fund

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.

This 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 at current levels. This example does not include the brokerage commissions that investors may pay to buy and sell Shares.

$284

$493

$1,096

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or "turns over" its portfolio). A higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the fiscal year ended October 31, 2021, the Fund's portfolio turnover rate was 0% of the average value of its portfolio.

Principal Investment Strategies

General Strategy Description.The Fund invests at least 80% of its net assets in FLexible EXchange® Options ("FLEX Options") that reference the iShares MSCI Emerging Markets ETF (the "Underlying ETF"). FLEX Options are exchange-traded options contracts with uniquely customizable terms. Although guaranteed for settlement by the Options Clearing Corporation (the "OCC"), FLEX Options are still subject to counterparty risk with the OCC and may be less liquid than more traditional exchange-traded options. Due to the unique mechanics of the Fund's strategy, the return an investor can expect to receive from an investment in the Fund has characteristics that are distinct from many other investment vehicles. It is important that an investor understand these characteristics before making an investment in the Fund.

In general, an option contract is an agreement between a buyer and seller that gives the purchaser of the option the right to buy or sell a particular asset at a specified future date at an agreed upon price. The reference asset for all of the Fund's FLEX Options is the Underlying ETF. The Underlying ETF is an exchange-traded fund which seeks to track a quarterly reviewed index, the MSCI Emerging Markets Index, designed to represent the performance of mid- and large-cap securities in emerging market countries. Through its use of FLEX Options on the Underlying ETF, the Fund has significant exposure to companies based in Asia, which, as of the date of this prospectus, includes companies located in China, as well as companies in the financials and information technology sectors. For more information on the Underlying ETF, please see the section of the prospectus entitled "Additional Information About the Fund's Principal Investment Strategies."

The pre-determined outcomes sought by the Fund, which include the buffer and cap discussed below (the "Outcomes"), are based upon the performance of the Underlying ETF's share price over an approximately one-year period from July 1 through June 30 of the following year (the "Outcome Period"). The current Outcome Period is from July 1, 2022 through June 30, 2023. Upon conclusion of the Outcome Period, the Fund will receive the cash value of all the FLEX Options it held for the prior Outcome Period. It will then invest in a new series of FLEX Options with an expiration date in approximately one year, and a new Outcome Period will begin. The Outcomes may only be realized by investors who continuously hold Shares from the commencement of the Outcome Period until its conclusion. Investors who purchase Shares after the Outcome Period has begun or sell Shares prior to the Outcome Period's conclusion may experience investment returns very different from those that the Fund seeks to provide.

The Fund's strategy has been specifically designed to produce the Outcomes based upon the performance of the Underlying ETF's share price (or its "price return") over the duration of the Outcome Period. The Fund will not receive or benefit from any dividend payments made by the Underlying ETF. The Fund is not an appropriate investment for income-seeking investors. If the Underlying ETF's share price increases over the duration of the Outcome Period, the Fund seeks to provide investors that hold Fund Shares for the entire Outcome Period with an increase in value that approximately matches the percentage increase experienced by the Underlying ETF's share price over the duration of the Outcome Period, up to an upside return cap (the "Cap") that represents the maximum percentage return an investor can achieve from an investment in Fund Shares for the Outcome Period. Therefore, even though the Fund's returns are based upon the performance of the Underlying ETF's share price, if the Underlying ETF's share price experiences returns for the Outcome Period in excess of the Cap, Fund shareholders will not participate in the excess returns.

2

The Cap is based upon prevailing market conditions at the time the Fund enters into the FLEX Options on the first day of the Outcome Period and will be further reduced by any shareholder transaction fees and any extraordinary expenses incurred by the Fund. For the current Outcome Period, the Cap is 19.07% prior to taking into account any fees or expenses charged to shareholders. When the Fund's annual Fund management fee of 0.89% of the Fund's average daily net assets is taken into account, the Cap is 18.18%. The Cap will be further reduced by any shareholder transaction fees and any extraordinary expenses incurred by the Fund. For the purpose of this prospectus, "extraordinary expenses" are non-recurring expenses that may incurred by the Fund outside of the ordinary course of its business, including, without limitation, costs incurred in connection with any claim, litigation, arbitration, mediation, government investigation or similar proceedings, indemnification expenses and expenses in connection with holding and/or soliciting proxies for a meeting of Fund shareholders. Since the Cap is based upon prevailing market conditions at the beginning of an Outcome Period, the Cap will therefore rise or fall from one Outcome Period to the next.

As is discussed in further detail below, it is anticipated that during the Outcome Period the Fund's NAV will not increase or decrease at the same rate as the Underlying ETF's share price. The Fund's NAV is based upon the value of its portfolio, which is primarily composed of FLEX Options. Although the value of the Underlying ETF's share price is a significant component of the value of the Fund's FLEX Options, the time remaining until those FLEX Options expire also affects their value. The Fund's investment sub-adviser, Milliman Financial Risk Management LLC ("Milliman" or the "Sub-Adviser"), generally anticipates that the Fund's NAV will increase on days when the Underlying ETF's share price increases and will decrease on days when the Underlying ETF's share price decreases, but that the rate of such increase or decrease will be less than that experienced by the Underlying ETF. The degree to which an option's value correlates with the value of the Underlying ETF is also affected by the expected volatility of the Underlying ETF. Since the Underlying ETF has the potential to be more volatile than other funds, in the period between the beginning and end of the Outcome Period, it is possible that the degree of non-correlation between the value of the FLEX Options and the value of the Underlying ETF will be higher than if the FLEX Options utilized a less volatile fund as their reference asset. The strategy is designed to realize the Outcomes only on the final day of the Outcome Period.

The Sub Adviser has constructed a portfolio principally composed of FLEX Options that reference the Underlying ETF that are each set to expire on the last day of the Outcome Period. The customizable nature of FLEX Options allows the Sub-Adviser to select the share price at which the Underlying ETF will be exercised at the expiration of each FLEX Option. This is commonly known as the "strike price." At the commencement of the Outcome Period, the Sub-Adviser specifically selects the strike price for each FLEX Option such that when the FLEX Options are exercised on the final day of the Outcome Period, the Outcomes may be obtained, depending on the performance of the Underlying ETF's share price over the duration of the Outcome Period.

The Fund seeks to generate returns that match the Underlying ETF, up to the Cap (discussed in detail below), while limiting downside losses. The two hypothetical graphical illustrations provided below are designed to illustrate the Outcomes that the Fund seeks to provide for investors who hold Fund Shares for the entirety of the Outcome Period.There is no guarantee that the Fund will be successful in its attempt to provide the Outcomes for an Outcome Period. The returns that the Fund seeks to provide do not include the costs associated with purchasing Fund Shares and certain expenses incurred by the Fund.

The following table contains hypothetical examples designed to illustrate the Outcomes the Fund seeks to provide over an Outcome Period, based upon the performance of the Underlying ETF from -100% to 100%. The table is provided for illustrative purposes and does not provide every possible performance scenario for Shares over the course of an Outcome Period. There is no guarantee that the Fund will be successful in its attempt to provide the Outcomes for an Outcome Period. The table is not intended to predict or project the performance of the FLEX Options or the Fund. Fund shareholders should not take this information as an assurance of the expected performance of the Underlying ETF or return on the Fund's Shares. The actual overall performance of the Fund will vary with fluctuations in the value of the FLEX Options during the Outcome Period, among other factors. Please refer to the Fund's website, www.innovatoretfs.com/ejul, which provides updated information relating to this table on a daily basis throughout the Outcome Period.

When the Fund's annual Fund management fee of 0.89% of the Fund's average daily net assets is taken into account, the Cap is 18.18%. The Fund's annual management fee of 0.89% of the Fund's average daily net assets, any shareholder transaction fees and any extraordinary expenses incurred by the Fund will have the effect of reducing the Cap and Buffer amounts for Fund shareholders.

Use of FLEX Options. The Outcomes may be achieved by purchasing and selling call and put FLEX Options to create layers within the Fund's portfolio. To achieve these returns, the Fund may purchase a combination of call options (giving the Fund the right to receive the cash value of the Underlying ETF's share price) and put options (giving the Fund the right to deliver the cash value of the Underlying ETF's share price), while simultaneously selling call options (giving the Fund the obligation to deliver the cash value of the Underlying ETF's share price) and put options (giving the Fund the obligation to receive the cash value of the Underlying ETF's share price). Each of these FLEX Options has a specifically selected strike price. The effect created by a first layer of FLEX Options positions is that if the Underlying ETF's share price has increased in value over the course of the Outcome Period, when the amount of cash the Fund receives and delivers pursuant to the terms of its positions is netted out, the Fund seeks to provide a gain that matches the gain experienced by the Underlying ETF. This gain is subject to the Cap, a maximum investment return level, which is discussed below.

A separate layer is designed to produce the Fund's "power" Buffer. "Power" denotes the Fund's objective to provide returns that are buffered by up to 15% if the Underlying ETF's share price experiences a loss during the course of the Outcome Period. There is no guarantee that the Fund will be successful in its attempt to provide buffered returns. The Buffer that the Fund seeks to provide is only operative against the first 15% of Underlying ETF losses for the Outcome Period. After the Underlying ETF's share price has decreased in value by more than 15%, the Fund will experience all subsequent losses on a one-to-one basis. In seeking to achieve the power Buffer, the Fund enters into FLEX Options positions that have a specifically selected strike price. The effect created by these positions is that if the Underlying ETF's share price has decreased in value over the course of the Outcome Period, when the amount of cash the Fund receives and delivers pursuant to the terms of its positions is netted out, the Fund seeks to be returned the amount of its principal investment (if the Underlying ETF's share price decreased in value by 15% or less) or experience a loss that is 15% less than the loss experienced by the Underlying ETF (if the Underlying ETF's share price decreased in value by more than 15%).

Each of the FLEX Options purchased and sold throughout the Outcome Period are expected to have the same or similar terms (i.e., strike price and expiration) as the corresponding FLEX Options purchased and sold on the first day of the Outcome Period. A detailed explanation regarding the terms of the FLEX Options and the mechanics of the Fund's strategy can be found in "Additional Information Regarding the Fund's Principal Investment Strategies."

The Outcome Period. The Outcomes sought by the Fund are based upon the Fund's NAV at the outset of the Outcome Period. The Outcome Period begins on the day the FLEX Options are entered into and ends on the day they expire. Each FLEX Option's value is ultimately derived from the performance of the Underlying ETF's share price during that time. Because the terms of the FLEX Options don't change, the Cap and Buffer both relate to the Fund's NAV on the first day of the Outcome Period. A shareholder that purchases Shares after the commencement of the Outcome Period will likely have purchased Shares at a different NAV than the NAV on the first day of the Outcome Period (the NAV upon which the Outcomes are based) and may experience investment outcomes very different from those sought by the Fund. A shareholder that sells Shares prior to the end of the Outcome Period may also experience investment outcomes very different from those sought by the Fund. To achieve the Outcomes sought by the Fund for the Outcome Period, an investor must be holding Shares at the time that the Fund enters into the FLEX Options and on the day those FLEX Options expire. There is no guarantee that the Fund will be successful in its attempt to provide the Outcomes.

The Fund's assets will be principally composed of FLEX Options, the value of which is derived from the performance of the underlying reference asset, the Underlying ETF's share price. However, because a component of an option's value is the number of days remaining until its expiration, during the Outcome Period, the Fund's NAV will not directly correlate on a day-to-day basis with the returns experienced by the Underlying ETF. The Sub-Adviser generally anticipates that the Fund's NAV will increase on days when the Underlying ETF's share price increases and will decrease on days when the Underlying ETF's share price decreases, but that the rate of such increase or decrease will be less than that experienced by the Underlying ETF. The degree to which an option's value correlates with the value of the Underlying ETF is also affected by the expected volatility of the Underlying ETF. Since the Underlying ETF has the potential to be more volatile than other funds, in the period between the beginning and end of the Outcome Period, it is possible that the degree of non-correlation between the value of the FLEX Options and the value of the Underlying ETF will be higher than if the FLEX Options utilized a less volatile fund as their reference asset. Similarly, the amount of time remaining until the end of the Outcome Period also affects the impact of the Buffer on the Fund's NAV, which may not be in full effect prior to the end of the Outcome Period. The Fund's strategy is designed to produce the Outcomes upon the expiration of the FLEX Options on the last day of the Outcome Period and it should not be expected that the Outcomes will be provided at any point prior to that time. Taken together, this means that at the midpoint of the Outcome Period, if the Underlying ETF's share price has decreased by 15%, the Fund's NAV can be expected to have decreased in value (because the Buffer is not yet in full effect), but by less than 15% (because the Fund's NAV will not correlate one-to-one with the Underlying ETF and the Fund's NAV tends not to participate fully in either Underlying ETF gains or losses).

Cap on Potential Upside Returns. Unlike other investment products, the potential upside return an investor can receive from an investment in Fund Shares over the Outcome Period is subject to the Cap. The Cap represents the maximum percentage return an investor can achieve from an investment in Fund Shares over the duration of the Outcome Period. Therefore, even though the Fund's returns are based upon the performance of the Underlying ETF's share price, if the Underlying ETF's share price experiences returns for the Outcome Period in excess of the Cap, the Fund will not participate in excess returns. The Cap is determined on the first day of the Outcome Period and is 19.07% prior to taking into account any fees or expenses charged to shareholders. When the Fund's annual Fund management fee of 0.89% of the Fund's average daily net assets is taken into account, the Cap is 18.18%. The Cap will be further reduced by any shareholder transaction fees and any extraordinary expenses incurred by the Fund. The Cap is also set forth on the Fund's website at www.innovatoretfs.com/ejul.

6

The Cap will change for each Outcome Period based upon prevailing market conditions at the beginning of the Outcome Period. The Cap, and the Fund's position relative to it, should be considered before investing in the Fund. If an investor is considering purchasing Shares during the Outcome Period, and the Fund has already increased in value to a level near to the Cap, an investor purchasing Shares at that price has limited to no gains available for the remainder of the Outcome Period but remains vulnerable to significant downside risks. There is no guarantee that the Fund will successfully achieve its investment objective.

The Cap is a result of the design of the Fund's principal investment strategy. In order to provide the Buffer, the Fund purchases a series of FLEX Options. As the purchaser of these FLEX Options, the Fund is obligated to pay a premium to the seller of those FLEX Options. However, the strategy is designed so that any premiums that the Fund is obligated to pay are offset by premiums it receives in connection with the selling of FLEX Options. On the first day of the Outcome Period when the Fund enters into its other FLEX Options positions, the portfolio managers will calculate the amount of premiums that the Fund will owe and will then go into the market and sell a FLEX Option with terms that entitle the Fund to receive a premium in an amount equal to the amount that the Fund would otherwise owe. The Cap is the strike price of that sold FLEX Option. The strike price is determined based upon prevailing market conditions at the time the Fund enters into the FLEX Options, most notably current interest rate levels, volatility in the Underlying ETF's share price, and the relationship of put and calls on the underlying FLEX Options.

Buffer. The power Buffer is only operative against the first 15% of Underlying ETF losses for the Outcome Period; however, there is no guarantee that the Fund will be successful in its attempt to provide buffered returns. After the Underlying ETF's share price has decreased by more than 15%, the Fund will experience all subsequent losses on a one-to-one basis. The Buffer is provided prior to taking into account annual Fund management fees, transaction fees and any extraordinary expenses incurred by the Fund. These fees and any expenses will have the effect of reducing the Buffer amount for Fund shareholders for an Outcome Period. When the Fund's annual management fee equal to 0.89% of the Fund's daily net assets is taken into account, the net Buffer for an Outcome Period is 14.11%. The Fund's strategy is designed to produce the Outcomes upon the expiration of its FLEX Options investments on the last day of the Outcome Period. It should not be expected that the Outcomes, including the net effect of the Fund's annual management fee on the Cap and Buffer, will be provided at any point prior to the last day of the Outcome Period. If an investor is considering purchasing Shares during the Outcome Period, and the Fund has already decreased in value by an amount equal to or greater than 15%, an investor purchasing Shares at that price will have increased gains available prior to reaching the Cap but may not benefit from the power Buffer that the Fund seeks to offer for the remainder of the Outcome Period. Conversely, if an investor is considering purchasing Shares during the Outcome Period, and the Fund has already increased in value, then a shareholder may experience losses prior to gaining the protection offered by the power Buffer, which is not guaranteed. A shareholder that purchases Shares at the beginning of the Outcome Period may lose their entire investment. While the Fund seeks to limit losses to 85% for shareholders who hold Shares for the entire Outcome Period, there is no guarantee it will successfully do so. Depending upon market conditions at the time of purchase, a shareholder that purchases Shares after the Outcome Period has begun may also lose their entire investment. An investment in the Fund is only appropriate for shareholders willing to bear those losses.

7

Fund Rebalance. The Fund is a continuous investment vehicle. It does not terminate and distribute its assets at the conclusion of each Outcome Period. On the termination date of an Outcome Period, the Sub-Adviser will invest in a new set of FLEX Options and another Outcome Period will commence.

Approximately one week prior to the end of each Outcome Period, the Fund will file a prospectus supplement, which will alert existing shareholders that an Outcome Period is approaching its conclusion and disclose the anticipated ranges for the Cap for the next Outcome Period. Following the close of business on the last day of the Outcome Period, the Fund will file a prospectus supplement that discloses the Fund's final Cap (both gross and net of the unitary management fee) for the next Outcome Period. This information is available on the Fund's website, www.innovatoretfs.com/ejul, which also provides information relating to the Outcomes, including the Fund's position relative to the Cap, of an investment in the Fund on a daily basis.

The Fund's website, www.innovatoretfs.com/ejul, provides information relating to the Outcomes, including the Fund's position relative to the Cap and Buffer, of an investment in the Fund on a daily basis.

The Fund is classified as "non-diversified" under the Investment Company Act of 1940, as amended (the "1940 Act").

Principal Risks

You could lose money by investing in the Fund.An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund's investment objectives will be achieved.

Buffered Loss Risk. There can be no guarantee that the Fund will be successful in its strategy to provide buffer protection against Underlying ETF losses if the Underlying ETF's share price decreases by 15% or less over the duration of the Outcome Period. A shareholder may lose their entire investment. The Fund's strategy seeks to deliver returns that match those of the Underlying ETF (up to the Cap), while limiting downside losses, if Shares are held at the time at which the Fund enters into the FLEX Options and held until those FLEX Options expire at the end of the Outcome Period. In the event an investor purchases Shares after the FLEX Options were entered into or sells Shares prior to the expiration of the FLEX Options, the Buffer that the Fund seeks to provide may not be available. The Fund does not provide principal protection or non-principal protection, and an investor may experience significant losses on its investment, including the loss of its entire investment.

Capped Upside Return Risk. The Fund's strategy seeks to provide returns that are subject to the Cap. In the event that the Underlying ETF experiences gains in excess of the Cap for the Outcome Period, the Fund will not participate in those gains beyond the Cap. The Fund's strategy seeks to deliver returns that match those of the Underlying ETF (up to the Cap), while limiting downside losses, if Shares are held at the time at which the Fund enters into the FLEX Options and held until those FLEX Options expire at the end of the Outcome Period. In the event an investor purchases Shares after the FLEX Options were entered into or sells Shares prior to the expiration of the FLEX Options, there may be little or no ability for that investor to experience an investment gain on their Shares.

8

FLEX Options Risk. The Fund will utilize FLEX Options issued and guaranteed for settlement by the OCC. The Fund bears the risk that the OCC will be unable or unwilling to perform its obligations under the FLEX Options contracts. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses. Additionally, FLEX Options may be less liquid than certain other securities, such as standardized options. In less liquid markets for the FLEX Options, the Fund may have difficulty closing out certain FLEX Options positions at desired times and prices. In connection with the creation and redemption of Shares, to the extent market participants are not willing or able to enter into FLEX Option transactions with the Fund at prices that reflect the market price of the Shares, the Fund's net asset value ("NAV") and, in turn the share price of the Fund, could be negatively impacted.

The Fund may experience substantial downside from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options held by the Fund are exercisable at the strike price on their expiration date. As a FLEX Option approaches its expiration date, its value typically increasingly moves with the value of the Underlying ETF. However, prior to such date, the value of the FLEX Options does not increase or decrease at the same rate as the Underlying ETF's share price on a day-to-day basis (although they generally move in the same direction). The value of the FLEX Options held by the Fund will be determined based on market quotations or other recognized pricing methods. The value of the underlying FLEX Options will be affected by, among others, changes in the Underlying ETF's share price, changes in interest rates, changes in the actual and implied volatility of the Underlying ETF and the remaining time to until the FLEX Options expire.

Options Risk. The use of option contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, changes in interest or currency exchange rates, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. There may at times be an imperfect correlation between the movement in values option contracts and the reference asset, and there may at times not be a liquid secondary market for certain option contracts.

Clearing Member Default Risk. Transactions in some types of derivatives, including FLEX Options, are required to be centrally cleared ("cleared derivatives"). In a transaction involving cleared derivatives, the Fund's counterparty is a clearing house, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house ("clearing members") can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for FLEX Options may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member's customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy.

9

Outcome Period Risk. The Fund's investment strategy is designed to deliver returns that match those of the Underlying ETF's share price if Shares are held from the time the Fund enters into the FLEX Options and held until those FLEX Options expire at the end of the Outcome Period. In the event an investor purchases Shares after the FLEX Options were entered into or sells Shares prior to the expiration of the FLEX Options, the returns realized by the investor will not match those that the Fund seeks to provide.

Underlying ETF Risk. Because the value of the FLEX Options held by the Fund are based on the value of the Underlying ETF, the Fund's investment performance largely depends on the investment performance and associated risks of the Underlying ETF. The Underlying ETF is subject to many of the same structural risks as the Fund that are described in more detail herein, such as Authorized Participant Concentration Risk, Fluctuation of Net Asset Value Risk, Market Maker Risk, Market Risk, Operational Risk and Trading Issues Risk. However, the risks of investing in an ETF also include the risks associated with the underlying investments held by the ETF. As such, the Fund may be subject to the following risks as a result of its exposure to the Underlying ETF through its usage of FLEX Options:

Currency Risk. Changes in currency exchange rates affect the value of investments denominated in a foreign currency, and therefore the value of the FLEX Options on the Underlying ETF in the Fund's portfolio. The Fund's NAV could decline if a currency to which the Fund has exposure depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably.

Emerging Markets Risk. Exposure to companies operating in emerging market countries involve additional risks relating to political, economic, or regulatory conditions not associated with investments in securities and instruments issued by U.S. companies or by companies operating in other developed market countries. Investments in emerging market securities are generally considered speculative in nature and are subject to the following heightened risks: smaller market capitalization of securities markets which may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; possible repatriation of investment income and capital; rapid inflation; and currency convertibility issues. Emerging market countries also often have less uniformity in accounting and reporting requirements, unsettled securities laws, unreliable securities valuation and greater risk associated with custody of securities. Furthermore, investors may be required to register the proceeds of sales and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies.

10

Equity Securities Risk. The Underlying ETF invests in equity securities, and therefore the Fund has exposure to the equity securities markets due to its investment in FLEX Options that reference the Underlying ETF. Equity securities may decline in value because of declines in the price of a particular holding or the broad stock market. Such declines may relate directly to the issuer of a security or broader economic or market events, including changes in interest rates. The value of shares will fluctuate with changes in the value of the equity securities the Underlying ETF invests in.

Financials Sector Risk. The Underlying ETF invests significantly in financials sector companies, which results in the Fund having significant exposure to such companies through its exposure to the Underlying ETF by virtue of its usage of FLEX Options. Financial companies, such as retail and commercial banks, insurance companies and financial services companies, are especially subject to the adverse effects of economic recession, currency exchange rates, extensive government regulation, decreases in the availability of capital, volatile interest rates, portfolio concentrations in geographic markets, industries or products (such as commercial and residential real estate loans) and competition from new entrants and blurred distinctions in their fields of business.

Information Technology Companies Risk. The Underlying ETF invests significantly in information technology companies, which results in the Fund having significant exposure to such companies through its exposure to the Underlying ETF by virtue of its usage of FLEX Options.Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

Non-U.S. Securities Risk. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments, restrictions on foreign investment or exchange of securities, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, different legal or accounting standards, and less government supervision and regulation of securities exchanges in foreign countries.

Smaller Companies Risk. The Underlying ETF invests in the securities of small and/or mid capitalization companies, which results in the Fund having significant exposure to such companies through its exposure to the Underlying ETF by virtue of its usage of FLEX Options. Small and/or mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

11

Asia Risk. Through its investments in FLEX Options on the Underlying ETF, the Fund is subject to certain risks specifically associated with investments in the securities of Asian issuers. Many Asian economies have experienced rapid growth and industrialization, and there is no assurance that this growth rate will be maintained. Some Asian economies are highly dependent on trade, and economic conditions in other countries within and outside Asia can impact these economies. Certain of these economies may be adversely affected by trade or policy disputes with its major trade partners. There is also a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries. Certain Asian countries have experienced and may in the future experience expropriation and nationalization of assets, confiscatory taxation, currency manipulation, political instability, armed conflict and social instability as a result of religious, ethnic, socio-economic and/or political unrest. In particular, escalated tensions involving North Korea and any outbreak of hostilities involving North Korea could have a severe adverse effect on Asian economies. Governments of certain Asian countries have exercised, and continue to exercise, substantial influence over many aspects of the private sector. In certain cases, the government owns or controls many companies, including the largest in the country. Accordingly, government actions could have a significant effect on the issuers of the Fund's securities or on economic conditions generally.

China Risk. Through its investments in FLEX Options on the Underlying ETF, the Fund is subject to certain risks specifically associated with investments in the securities of Chinese issuers. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. The central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership and actions of the Chinese central and local government authorities continue to have a substantial effect on economic conditions in China. Export growth continues to be a major driver of China's rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China's key trading partners may have an adverse impact on the Chinese economy. Recent developments in relations between the U.S. and China have heightened concerns of increased tariffs and restrictions on trade between the two countries. An increase in tariffs or trade restrictions, or even the threat of such developments, could lead to a significant reduction in international trade, which could have a negative impact on China's export industry and a commensurately negative impact on the Fund. From time to time and as recently as January 2020, China has experienced outbreaks of infectious illnesses, and the country may be subject to other public health threats, infectious illnesses, diseases or similar issues in the future. Any spread of an infectious illness, public health threat or similar issue could reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, and generally have a significant impact on the Chinese economy, which in turn could adversely affect the Fund's investments.

12

Correlation Risk. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. As a FLEX Option approaches its expiration date, its value typically will increasingly move with the value of the Underlying ETF. However, prior to the expiration date, the value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. The value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. Factors that may influence the value of the FLEX Options include interest rate changes and implied volatility levels of the Underlying ETF, among others. The value of the FLEX Options held by the Fund typically do not increase or decrease at the same level as the Underlying ETF's share price on a day-to-day basis due to these factors (although they generally move in the same direction). Since the Underlying ETF has the potential to be more volatile than other funds, in the period between the beginning and end of the Outcome Period, it is possible that the degree of non-correlation between the value of the FLEX Options and the value of the Underlying ETF will be higher than if the FLEX Options utilized a less volatile fund as their reference asset.

Investment Objective Risk. Certain circumstances under which the Fund might not achieve its objective include, but are not limited, to (i) if the Fund disposes of FLEX Options, (ii) if the Fund is unable to maintain the proportional relationship based on the number of FLEX Options in the Fund's portfolio, (iii) significant accrual of Fund expenses in connection with effecting the Fund's principal investment strategy or (iv) adverse tax law changes affecting the treatment of FLEX Options.

Upside Participation Risk. There can be no guarantee that the Fund will be successful in its strategy to provide shareholders with a total return that matches the increase of the Underlying ETF over the Outcome Period, subject to a maximum return imposed by the Cap. In the event an investor purchases Shares after the FLEX Options were entered into or does not stay invested in the Fund for the entirety of the Outcome Period, the returns realized by the investor may not match those that the Fund seeks to achieve.

Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. The Sub-Adviser applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that the Fund will meet its investment objective.

Cap Change Risk. A new Cap is established at the beginning of each Outcome Period and is dependent on prevailing market conditions. As such, the Cap may rise or fall from one Outcome Period to the next and is unlikely to remain the same for consecutive Outcome Periods.

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. Assets may decline in value due to factors affecting financial markets generally or particular asset classes or industries represented in the markets. The value of FLEX Options or other assets may also decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or other asset, or due to factors that affect a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class. During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates will not have the same impact on all types of securities. Securities, including the Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments.

13

Non-Diversification Risk.The Fund is classified as "non-diversified" under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the "Code"). The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

Liquidity Risk. In the event that trading in the underlying FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. There is no guarantee that a liquid secondary trading market will exist for the FLEX Options. The trading in FLEX Options may be less deep and liquid than the market for certain other securities, including certain non-customized options. In a less liquid market for the FLEX Options, terminating the FLEX Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment.

Valuation Risk. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the FLEX Options becomes more difficult and the judgment of the Fund's investment adviser (employing the fair value procedures adopted by the Board of Trustees of the Trust (the "Board")) may play a greater role in the valuation of the Fund's holdings due to reduced availability of reliable objective pricing data. Consequently, while such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error in the calculation of the Cap, 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 its investment adviser and Sub-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.

Market Maker Risk. If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's NAV and the price at which the Shares are trading on the Exchange, which could result in a decrease in value of the Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Shares trading at a discount to NAV and in greater than normal intra-day bid-ask spreads for Shares.

Trading Issues Risk. Although the Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for such Shares will develop or be maintained. Shares trade on the Exchange at market price that may be below, at or above the Fund's NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange "circuit breaker" rules. Market makers are under no obligation to make a market in the Shares, and authorized participants are not obligated to submit purchase or redemption orders for Creation Units. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

14

Authorized Participant Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as authorized participants on an agency basis (i.e., on behalf of other market participants). To the extent that authorized participants exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other authorized participant is able to step forward to create or redeem "Creation Units" (large blocks of a specified number of Shares), Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts and/or delisting.

Counterparty Risk. Counterparty risk is the risk an issuer, guarantor or counterparty of a security in the Fund is unable or unwilling to meet its obligation on the security. Counterparty risk may arise because of the counterparty's financial condition, market activities, or for other reasons. The Fund may be unable to recover its investment from the counterparty or may obtain a limited and/or delayed recovery. The OCC acts as guarantor and central counterparty with respect to the FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses.

Fluctuation of Net Asset Value Risk. The Fund's Shares trade on the Exchange at their market price rather than their NAV. The market price may be at, above or below the Fund's NAV. Differences in market price and NAV may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Shares will be closely related to, but not identical to, the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. These differences can be especially pronounced during times of market volatility or stress. During these periods, the demand for Shares may decrease considerably and cause the market price of Shares to deviate significantly from the Fund's NAV.

Cash Transactions Risk. The Fund may effectuate all or a portion of its creations and redemptions for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in an ETF that effects its creations and redemptions only on an in-kind basis. ETFs are able to make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. A fund that effects redemptions for cash may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. Any recognized gain on these sales by the fund will generally cause such fund to recognize a gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities only in-kind. The Fund intends to distribute gains that arise by virtue of creations and redemptions being effectuated in cash to shareholders to avoid being taxed on this gain at the fund level and otherwise comply with special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than if they had made an investment in another ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares principally in-kind, will be passed on to those purchasing and redeeming Creation Units in the form of creation and redemption transaction fees. In addition, these factors may result in wider spreads between the bid and the offered prices of Fund Shares than for ETFs that distribute portfolio securities in-kind. The Fund's use of cash for creations and redemptions could also result in dilution to the Fund and increased transaction costs, which could negatively impact the Fund's ability to achieve its investment objective.

15

Cyber Security Risk. As the use of Internet technology has become more prevalent in the course of business, the investment industry has become more susceptible to potential operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund's digital information systems through "hacking" or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the Fund's third-party service providers, such as its administrator, transfer agent, custodian, or issuers in which the Fund invests, can also subject the Fund to many of the same risks associated with direct cyber security breaches. The Fund has established risk management systems designed to reduce the risks associated with cyber security. However, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company ("RIC") under Subchapter M of the Code. However, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund's options strategy, its hedging strategy, the possible application of the "straddle" rules, and various loss limitation provisions of the Code. If, in any year, the Fund fails to qualify as a RIC under the applicable tax laws, the Fund would be taxed as an ordinary corporation. Certain options on an ETF may not qualify as "Section 1256 contracts" under Section 1256 of the Code, and disposition of such options will likely result in short-term capital gains or losses. The Fund intends to treat any income it may derive from the FLEX Options as "qualifying income" under the provisions of the Code applicable to RICs. In addition, based upon language in the legislative history, the Fund intends to treat the issuer of the FLEX Options as the referenced asset, which, assuming the referenced asset qualifies as a RIC, would allow the Fund to qualify for special rules in the RIC diversification requirements. If the income is not qualifying income or the issuer of the FLEX Options is not appropriately the referenced asset, the Fund could lose its own status as a RIC. In the event that a shareholder purchases Shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

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

Performance

On July 1, 2021, the Fund ceased to invest in FLEX Options on the MSCI Emerging Markets Price Return Index, and instead began investing in FLEX Options on the iShares MSCI Emerging Markets ETF. Therefore, the Fund's performance and historical returns for the periods prior to July 1, 2021 are not necessarily indicative of the performance that the Fund, based on its current investments, would have generated.

The bar chart and table below illustrate the annual calendar year returns of the Fund based on NAV as well as the average annual Fund returns. The bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year and by showing how the Fund's average annual total returns based on NAV compare to those of two broad-based market indices: the MSCI Emerging Markets Total Return Index and the MSCI Emerging Markets Price Index. Both indices have the same constituents in the same weights. However, the MSCI Emerging Markets Total Return Index assumes that any dividends paid out by index constituents have been reinvested in the index and the MSCI Emerging Markets Price Return Index, which measures only the price movements of index constituents, does not. Although the Outcomes the Fund seeks to provide are based upon the price performance of the Underlying ETF, the returns of the MSCI Emerging Markets Total Return Index have been provided in accordance with the requirements of Form N-1A of the 1940 Act. The Fund's performance information is accessible on the Fund's website at www.innovatoretfs.com.

Portfolio Managers

The following persons serve as portfolio managers of the Fund.

• Robert T. Cummings, Principal and Director of Global Trading at Milliman

• Yin Bhuyan, Associate - ETF Portfolio Management Team at Milliman

Each of the portfolio managers is primarily and jointly responsible for the day-to-day management of the Fund. Mr. Cummings has served in this capacity since the Fund's inception in June 2019. Ms. Bhuyan has served in this capacity since March 2021.

Purchase and Sale of Shares

The Fund issues and redeems Shares at NAV only with authorized participants ("APs") that have entered into agreements with the Fund's distributor and only in Creation Units or multiples thereof ("Creation Unit Aggregations"), in exchange for cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

18

Individual Shares may only be bought and sold in the secondary market (i.e., on a national securities exchange) through a broker or dealer at a market price. Because the Shares trade at market prices rather than NAV, Shares may trade at a price greater than NAV (at a premium), at NAV, or less than NAV (at a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying or selling shares in the secondary market (the "bid-ask spread").

Recent information, including information on the Fund's NAV, market price, premiums and discounts, and bid-ask spreads, is available online at www.innovatoretfs.com.

TaxInformation

The Fund's distributions will generally be taxable as ordinary income, returns of capital or capital gains. A sale of Shares may result in capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank), Innovator and Foreside Fund Services, LLC, the Fund's distributor (the "Distributor"), may pay the intermediary for the sale of Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

Additional Information About the Fund's Principal Investment Strategies '

The Fund's principal investment strategy seeks to produce the Outcomes based upon the performance of the Underlying ETF. If the Underlying ETF's share price increases in value over the duration of the Outcome Period, the Fund seeks to provide Fund shareholders that hold Shares for the entire Outcome Period with an increase in value that approximately matches the increase experienced by the Underlying ETF, subject to the Cap. If the Underlying ETF's share price decreases in value over the duration of the Outcome Period, the Fund seeks to provide Fund shareholders that hold Shares for the entire Outcome Period with a Buffer against Underlying ETF losses of 15% or less. All investment gains are subject to the Cap. Both the Cap and the Buffer are provided prior to taking into account annual Fund management fees equal to 0.89% of the Fund's daily net assets, transaction fees and any extraordinary expenses incurred by the Fund. Such expenses will reduce the Cap. The Fund's annual management fee of 0.89% of the Fund's average daily net assets, any shareholder transaction fees and any extraordinary expenses incurred by the Fund will have the effect of reducing the Buffer amount for Fund shareholders. There is no guarantee that the Fund will be successful in its attempt to provide buffered returns.

The Underlying ETF is an exchange-traded fund that seeks to track a free float-adjusted market capitalization index, the MSCI Emerging Markets Index, designed to measure the equity market performance of large- and mid-cap securities in emerging market countries. The Underlying ETF provides exposure to companies located in the following 26 emerging market countries: Argentina, Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Malaysia, Mexico, Pakistan, Peru, Philippines, Poland, Qatar, Russia, Saudi Arabia, South Africa, Taiwan, Thailand, Turkey and the United Arab Emirates. The Underlying ETF is reviewed quarterly in February, May, August and November with the objective of reflecting changes in the index equity markets in a timely manner.

In general, an option contract is an agreement between a buyer and seller that gives the purchaser of the option the right to buy or sell a particular asset at a specified future date at an agreed upon price (commonly known as the "strike price"). FLEX Options are exchange-traded options contracts with uniquely customizable terms. Each FLEX Option contract that the Fund enters into references the Underlying ETF and expires on the last day of the Outcome Period. The FLEX Options, however, have varying strike prices. The layering of these FLEX Options with varying strike prices provides the mechanism for producing the Fund's desired outcomes.

21

The combination of purchases and sales of call and put FLEX Options provide upside participation that matches that of the Underlying ETF's share price. At the expiration date, these FLEX Options realize a value equal to that of the Underlying ETF's share price.

Taken together, the purchase and sale of put FLEX Options produces the 15% "power Buffer." The payoff at expiration will compensate for losses experienced by the Underlying ETF (if any), in an amount not to exceed 15%.

The strike level of a short call FLEX Option produces the Cap and is chosen so that the combined net purchase prices in all of the FLEX Options is approximately equal to the Fund's NAV.

The combination of all of the FLEX Options creates a maximum growth opportunity equal to the return experienced by the Underlying ETF at expiration, not to exceed the Cap, while providing a 15% Buffer from losses.

As described on the cover of this prospectus, in "Principal Investment Strategies" and in "Principal Risks," there are risks associated with an investment in the Fund and there is no guarantee the Fund achieve the Outcomes it seeks to provide. The Fund's unique characteristics (i.e., the imperative of holding Shares for the entire Outcome Period, the Cap and Buffer) distinguish it from other investment products and may make it an unsuitable some investors. To help decide whether an investment in the Fund is appropriate based upon individual circumstances, please see the section of this prospectus entitled "Investor Suitability."

The Fund's investment objective may be changed by the Board without shareholder approval. Additionally, the Fund may liquidate and terminate at any time without shareholder approval.

FLEX Options

FLEX Options are customized option contracts that trade on an exchange but provide investors with the ability to customize key contract terms like strike price, style and expiration date while achieving price discovery in competitive, transparent auctions markets and avoiding the counterparty exposure of over-the-counter options positions. Like traditional exchange-traded options, FLEX Options are guaranteed for settlement by the OCC, a market clearinghouse that guarantees performance by counterparties to certain derivatives contracts.

The FLEX Options in which the Fund will invest are all European style options (options that are exercisable only on the expiration date). The FLEX Options are listed on the Chicago Board Options Exchange.

The Fund will purchase and sell call and put FLEX Options. In general, put options give the holder (i.e., the buyer) the right to sell an asset (or deliver the cash value of the asset, in case of certain put options) and the seller (i.e., the writer) of the put has the obligation to buy the asset (or receive cash value of the asset, in case of certain put options) at a certain defined price. Call options give the holder (i.e., the buyer) the right to buy an asset (or receive cash value of the asset, in case of certain call options) and the seller (i.e., the writer) the obligation to sell the asset (or deliver cash value of the asset, in case of certain call options) at a certain defined price.

The Fund will use the market value of its derivatives holdings for the purpose of determining compliance with the 1940 Act and the rules promulgated thereunder. Since the FLEX Options held by the Fund are exchange-traded, these will be valued on a mark-to-market basis. In the event market prices are not available, the Fund will use fair value pricing pursuant to the fair value procedures adopted by the Board.

Non-Principal Investments

Cash Equivalents and Short-Term Investments

The Fund may invest in securities with maturities of less than one year or cash equivalents, or it may hold cash. The percentage of the Fund invested in such holdings varies and depends on several factors, including market conditions.

Traditional Options Contracts

Option contracts on an individual security, such as an ETF, give one party the right to buy or sell the particular security, and another party the obligation to sell or buy that same security. Many options are exchange-traded and are available to investors with set or defined contract terms (standardized options) and are settled through a clearing house and are guaranteed. There are also options contracts that trade "over-the-counter" ("OTC"), which are traded between two private parties, are not standardized and not guaranteed. To the extent the Fund may utilize traditional options contracts, it intends to use standardized listed options.

Disclosure of Portfolio Holdings

A description of the Trust's policies and procedures with respect to the disclosure of the Fund's portfolio holdings is available in the Fund's statement of additional information ("SAI"), which is available at www.innovatoretfs.com.

Additional Risks of Investing in the Fund

Risk is inherent in all investing. Investing in the Fund involves risk, including the risk that you may lose all or part of your investment. There can be no assurance that the Fund will meet its stated objective. Before you invest, you should consider the following supplemental disclosure pertaining to the Principal Risks set forth above as well as additional Non-Principal Risks set forth below in this prospectus.

Principal Risks

Buffered Loss Risk. There can be no guarantee that the Fund will be successful in its strategy to provide buffer protection against Underlying ETF losses if the Underlying ETF's share price decreases by 15% or less over the duration of the Outcome Period. A shareholder may lose their entire investment. The Fund's strategy seeks to deliver returns that match those of the Underlying ETF (up to the Cap), while limiting downside losses, if Shares are held at the time at which the Fund enters into the FLEX Options and held until those FLEX Options expire at the end of the Outcome Period. In the event an investor purchases Shares after the FLEX Options were entered into or sells Shares prior to the expiration of the FLEX Options, the Buffer that the Fund seeks to provide may not be available. The Fund does not provide principal protection or non-principal protection and an investor may experience significant losses on its investment, including the loss of its entire investment.

Capped Upside Return Risk. The Fund's strategy seeks to provide returns that are subject to the Cap. In the event that the Underlying ETF experiences gains in excess of the Cap for the Outcome Period, the Fund will not participate in those gains beyond the Cap. The Fund's strategy seeks to deliver returns that match those of the Underlying ETF (up to the Cap), while limiting downside losses, if Shares are held at the time at which the Fund enters into the FLEX Options and held until those FLEX Options expire at the end of the Outcome Period. In the event an investor purchases Shares after the FLEX Options were entered into or sells Shares prior to the expiration of the FLEX Options, there may be little or no ability for that investor to experience an investment gain on their Shares.

FLEX Options Risk. The Fund will utilize FLEX Options issued and guaranteed for settlement by the OCC. The Fund bears the risk that the OCC will be unable or unwilling to perform its obligations under the FLEX Options contracts. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses. Additionally, FLEX Options may be less liquid than certain other securities, such as standardized options. In less liquid markets for the FLEX Options, the Fund may have difficulty closing out certain FLEX Options positions at desired times and prices. In connection with the creation and redemption of Shares, to the extent market participants are not willing or able to enter into FLEX Option transactions with the Fund at prices that reflect the market price of the Shares, the Fund's NAV and, in turn the share price of the Fund, could be negatively impacted.

24

The Fund may experience substantial downside from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options held by the Fund are exercisable at the strike price on their expiration date. As a FLEX Option approaches its expiration date, its value typically increasingly moves with the value of the Underlying ETF. However, prior to such date, the value of the FLEX Options does not increase or decrease at the same rate as the Underlying ETF's share price on a day-to-day basis (although they generally move in the same direction). The value of the FLEX Options held by the Fund will be determined based on market quotations or other recognized pricing methods. The value of the underlying FLEX Options will be affected by, among others, changes in the Underlying ETF's share price, changes in interest rates, changes in the actual and implied volatility of the Underlying ETF and the remaining time to until the FLEX Options expire.

Options Risk. The use of option contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, changes in interest or currency exchange rates, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. There may at times be an imperfect correlation between the movement in values option contracts and the reference asset, and there may at times not be a liquid secondary market for certain option contracts.

Clearing Member Default Risk. Transactions in some types of derivatives, including FLEX Options, are required to be centrally cleared ("cleared derivatives"). In a transaction involving cleared derivatives, the Fund's counterparty is a clearing house, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house ("clearing members") can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for FLEX Options may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member's customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy.

Outcome Period Risk. The Fund's investment strategy is designed to deliver returns that match those of the Underlying ETF's share price if Shares are held from the time the Fund enters into the FLEX Options and held until those FLEX Options expire at the end of the Outcome Period. In the event an investor purchases Shares after the FLEX Options were entered into or sells Shares prior to the expiration of the FLEX Options, the returns realized by the investor will not match those that the Fund seeks to provide.

25

Underlying ETF Risk. Because the value of the FLEX Options held by the Fund are based on the value of the Underlying ETF, the Fund's investment performance largely depends on the investment performance and associated risks of the Underlying ETF. The Underlying ETF is subject to many of the same structural risks as the Fund that are described in more detail herein, such as Authorized Participant Concentration Risk, Fluctuation of Net Asset Value Risk, Market Maker Risk, Market Risk, Operational Risk and Trading Issues Risk. However, the risks of investing in an ETF also include the risks associated with the underlying investments held by the ETF. As such, the Fund may be subject to the following risks as a result of its exposure to the Underlying ETF through its usage of FLEX Options:

Currency Risk. Changes in currency exchange rates affect the value of investments denominated in a foreign currency, and therefore the value of the FLEX Options on the Underlying ETF in the Fund's portfolio. The Fund's NAV could decline if a currency to which the Fund has exposure depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably.

Emerging Markets Risk. Exposure companies operating in emerging market countries involves additional risks relating to political, economic, or regulatory conditions not associated with investments in securities and instruments issued by U.S. companies or by companies operating in other developed market countries. This is due to, among other things, the potential for greater market volatility, lower trading volume, higher levels of inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments in emerging market countries than are typically found in more developed market countries. Moreover, emerging market countries often have less uniformity in accounting and reporting requirements, unsettled securities laws, less reliable securities valuations and greater risks associated with custody of securities than developed markets. In addition, emerging market countries often have greater risk of capital controls through such measures as taxes or interest rate control than developed markets. Certain emerging market countries may also lack the infrastructure necessary to attract large amounts of foreign trade and investment. Local securities markets in emerging market countries may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible. Settlement procedures in emerging market countries are frequently less developed and reliable than those in the U.S. and other developed market countries. In addition, significant delays may occur in registering the transfer of securities. Settlement or registration problems may make it more difficult for a Fund to value its portfolio securities and could cause the Fund to miss attractive investment opportunities. Investing in emerging market countries involves a higher risk of expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested by certain emerging market countries. Enforcing legal rights may be made difficult, costly and slow in emerging markets as there may be additional problems enforcing claims against non-U.S. governments.

26

Equity Securities Risk. The Underlying ETF invests in equity securities, and therefore the Fund has exposure to the equity securities markets due to its investment in FLEX Options that reference the Underlying ETF. Investments in equity securities are subject to market risks that may cause their prices to fluctuate over time. The value of your investment in the Fund is based on the market prices of the securities to which the Underlying ETF has exposure. These prices change daily due to economic and other events that affect particular companies and other issuers or the market as a whole. Historically, the equity markets have moved in cycles so that the value of the Underlying ETF's equity securities may fluctuate from day-to-day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments and the prices of their securities may suffer a decline in response.

Financials Sector Risk. The Underlying ETF invests significantly in financials sector companies, which results in the Fund having significant exposure to such companies through its exposure to the Underlying ETF by virtue of its usage of FLEX Options.Financial companies are subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge, the amount and types of capital they must maintain and, potentially, their size. Governmental regulation may change frequently and may have significant adverse consequences for financial companies, including effects not intended by such regulation. The impact of more stringent capital requirements, or recent or future regulation in various countries, on any individual financial company or on financial companies as a whole cannot be predicted. Certain risks may impact the value of investments in financial companies more severely than those of investments in other issuers, including the risks associated with companies that operate with substantial financial leverage. Financial companies may also be adversely affected by volatility in interest rates, loan losses and other customer defaults, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Insurance companies in particular may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability.

Information Technology Companies Risk. The Underlying ETF invests significantly in information technology companies, which results in the Fund having significant exposure to such companies through its exposure to the Underlying ETF by virtue of its usage of FLEX Options.Information technology companies produce and provide hardware, software and information technology systems and services. Information technology companies are generally subject to the following risks: rapidly changing technologies and existing produce obsolescence; short product life cycles; fierce competition; aggressive pricing and reduced profit margins; the loss of patent, copyright and trademark protections; cyclical market patterns; evolving industry standards; and frequent new product introductions and new market entrants. Information technology companies may be smaller and less experienced companies, with limited product lines, markets or financial resources and fewer experienced management or marketing personnel. Information technology company stocks, particularly those involved with the internet, have experienced extreme price and volume fluctuations that are often unrelated to their operating performance. In addition, information technology companies are particularly vulnerable to federal, state and local government regulation, and competition and consolidation, both domestically and internationally, including competition from foreign competitors with lower production costs. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action. Information technology companies also face competition for services of qualified personnel and heavily rely on patents and intellectual property rights and the ability to enforce such rights to maintain a competitive advantage.

27

Non-U.S. Securities Risk. An investment in securities of non-U.S. companies involves risks not associated with domestic issuers. Investment in non-U.S. securities may involve higher costs than investment in U.S. securities, including higher transaction and custody costs as well as the imposition of additional taxes by non-U.S. governments. Non-U.S. investments may also involve risks associated with the level of currency exchange rates, less complete financial information about the issuers, less market liquidity, more market volatility and political instability. Future political and economic developments, the possible imposition of withholding taxes on dividend income, the possible seizure or nationalization of non-U.S. holdings, the possible establishment of exchange controls or freezes on the convertibility of currency or the adoption of other governmental restrictions might adversely affect an investment in non-U.S. securities. Additionally, non-U.S. issuers may be subject to less stringent regulation, and to different accounting, auditing and recordkeeping requirements. The U.S. and non-U.S. markets often rise and fall at different times or by different amounts due to economic or other regional developments particular to a given country or region.

Smaller Companies Risk. The Underlying ETF invests in the securities of small and/or mid capitalization companies, which results in the Fund having significant exposure to such companies through its exposure to the Underlying ETF by virtue of its usage of FLEX Options. Small and/or mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

Asia Risk. Through its investment in FLEX Options on the Underlying ETF, the Fund is subject to certain risks specifically associated with investments in the securities of Asian issuers. Many Asian economies have experienced rapid growth and industrialization, and there is no assurance that this growth rate will be maintained. Some Asian economies are highly dependent on trade, and economic conditions in other countries within and outside Asia can impact these economies. Certain of these economies may be adversely affected by trade or policy disputes with its major trade partners. There is also a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries. Certain Asian countries have experienced and may in the future experience expropriation and nationalization of assets, confiscatory taxation, currency manipulation, political instability, armed conflict and social instability as a result of religious, ethnic, socio-economic and/or political unrest. In particular, escalated tensions involving North Korea and any outbreak of hostilities involving North Korea could have a severe adverse effect on Asian economies. Governments of certain Asian countries have exercised, and continue to exercise, substantial influence over many aspects of the private sector. In certain cases, the government owns or controls many companies, including the largest in the country. Accordingly, government actions could have a significant effect on the issuers comprising the Underlying ETF, or on economic conditions generally. Issuers in Asia may not be subject to the same accounting, auditing and financial reporting standards as U.S. companies and if their securities are not listed on a U.S. exchange, they may not be subject to the same corporate governance standards as U.S. issuers.

28

China Risk. Through its investment in FLEX Options on the Underlying ETF, the Fund is subject to certain risks specifically associated with investments in the securities of Chinese issuers. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. The central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership and actions of the Chinese central and local government authorities continue to have a substantial effect on economic conditions in China. Furthermore, China's economy is dependent on the economies of other Asian countries and can be significantly affected by currency fluctuations and increasing competition from Asia's other emerging economies. China has experienced security concerns, such as terrorism and strained international relations. Incidents involving China's or the region's security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the value of the Fund's investments. Export growth continues to be a major driver of China's rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China's key trading partners may have an adverse impact on the Chinese economy. Recent developments in relations between the U.S. and China have heightened concerns of increased tariffs and restrictions on trade between the two countries. An increase in tariffs or trade restrictions, or even the threat of such developments, could lead to a significant reduction in international trade, which could have a negative impact on China's export industry and a commensurately negative impact on the Fund. From time to time and as recently as January 2020, China has experienced outbreaks of infectious illnesses, and the country may be subject to other public health threats, infectious illnesses, diseases or similar issues in the future. Any spread of an infectious illness, public health threat or similar issue could reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, and generally have a significant impact on the Chinese economy, which in turn could adversely affect the Fund's investments.

Correlation Risk. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. As a FLEX Option approaches its expiration date, its value typically will increasingly move with the value of the Underlying ETF. However, prior to the expiration date, the value of the FLEX Options prior to the expiration date may vary because of related factors other than the value of the Underlying ETF. The value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. Factors that may influence the value of the FLEX Options include interest rate changes and implied volatility levels of the Underlying ETF, among others. The value of the FLEX Options held by the Fund typically do not increase or decrease at the same level as the Underlying ETF's share price on a day-to-day basis due to these factors (although they generally move in the same direction). Since the Underlying ETF has the potential to be more volatile than other funds, in the period between the beginning and end of the Outcome Period, it is possible that the degree of non-correlation between the value of the FLEX Options and the value of the Underlying ETF will be higher than if the FLEX Options utilized a less volatile fund as their reference asset.

Investment Objective Risk. Certain circumstances under which the Fund might not achieve its objective include, but are not limited, to (i) if the Fund disposes of FLEX Options, (ii) if the Fund is unable to maintain the proportional relationship based on the number of FLEX Options in the Fund's portfolio, (iii) significant accrual of Fund expenses in connection with effecting the Fund's principal investment strategy or (iv) adverse tax law changes affecting the treatment of FLEX Options.

29

Upside Participation Risk. There can be no guarantee that the Fund will be successful in its strategy to provide shareholders with a total return that matches the increase of the Underlying ETF over the Outcome Period, subject to a maximum return imposed by the Cap. In the event an investor purchases Shares after the FLEX Options were entered into or does not stay invested in the Fund for the entirety of the Outcome Period, the returns realized by the investor may not match those that the Fund seeks to achieve.

Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. The Sub-Adviser applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that the Fund will meet its investment objective.

Cap Change Risk. A new Cap is established at the beginning of each Outcome Period and is dependent on prevailing market conditions. As such, the Cap may rise or fall from one Outcome Period to the next and is unlikely to remain the same for consecutive Outcome Periods.

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. Assets may decline in value due to factors affecting financial markets generally or particular asset classes or industries represented in the markets. The value of FLEX Options or other assets may also decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or other asset, or due to factors that affect a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class. During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates will not have the same impact on all types of securities. Securities, including the Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments.In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on a Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of a Fund's portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of a Fund's Shares and result in increased market volatility. During any such events, a Fund's Shares may trade at increased premiums or discounts to their NAV. The outbreak of the respiratory disease designated as "COVID-19," which was first detected in late 2019, resulted in significant disruptions to business operations, customer activity and service capabilities for companies throughout the world. The COVID-19 pandemic also greatly increased market volatility. Many countries continue to react to the COVID-19 pandemic through prevention measures and government intervention, including restrictions on travel and business operations. These measures, along with the general uncertainty caused by this pandemic, emerging variants, and the efficacy of vaccines, have resulted in a decline in consumer demand, disruptions to healthcare systems and the supply chain, ratings downgrades, defaults and has imposed significant costs on governmental and business entities. Certain markets have experienced temporary closures, extreme volatility, reduced liquidity, severe losses and increased trading costs, all of which could negatively impact the Fund. The future potential economic impact of the COVID-19 pandemic, or any future public health crisis, is impossible to predict and could result in adverse market conditions that impact the performance of the Fund.

30

Non-Diversification Risk. The Fund is classified as "non-diversified" under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Code. The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

Liquidity Risk. In the event that trading in the underlying FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. There is no guarantee that a liquid secondary trading market will exist for the FLEX Options. The trading in FLEX Options may be less deep and liquid than the market for certain other securities, including certain non-customized options. In a less liquid market for the FLEX Options, terminating the FLEX Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. In a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment.

Valuation Risk. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the FLEX Options becomes more difficult and the judgment of the Fund's investment adviser (employing the fair value procedures adopted by the Board may play a greater role in the valuation of the Fund's holdings due to reduced availability of reliable objective pricing data. Consequently, while such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error in the calculation of the Cap, 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 its Adviser and Sub-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.

Market Maker Risk. If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's NAV and the price at which the Shares are trading on the Exchange, which could result in a decrease in value of the Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Shares trading at a discount to NAV and in greater than normal intra-day bid-ask spreads for Shares.

31

Trading Issues Risk. Although the Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for such Shares will develop or be maintained. Shares trade on the Exchange at market prices that may be below, at or above the Fund's NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange "circuit breaker" rules. Market makers are under no obligation to make a market in the Shares, and authorized participants are not obligated to submit purchase or redemption orders for Creation Units. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Authorized Participant Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as authorized participants on an agency basis (i.e., on behalf of other market participants). To the extent that authorized participants exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other authorized participant is able to step forward to create or redeem Creation Units, Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts and/or delisting.

Counterparty Risk. Counterparty risk is the risk an issuer, guarantor or counterparty of a security in the Fund is unable or unwilling to meet its obligation on the security. Counterparty risk may arise because of the counterparty's financial condition, market activities, or for other reasons. The Fund may be unable to recover its investment from the counterparty or may obtain a limited and/or delayed recovery. The OCC acts as guarantor and central counterparty with respect to the FLEX Options. As a result, the ability of the Fund to meet its objective depends on the OCC being able to meet its obligations. In the unlikely event that the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses.

Fluctuation of Net Asset Value Risk. The Fund's Shares trade on the Exchange at their market price rather than their NAV. The market price may be at, above or below the Fund's NAV. Differences in market price and NAV may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Shares will be closely related to, but not identical to, the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. These differences can be especially pronounced during times of market volatility or stress. During these periods, the demand for Shares may decrease considerably and cause the market price of Shares to deviate significantly from the Fund's NAV.

Cash Transactions Risk. The Fund may effectuate all or a portion of its creations and redemptions for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in an ETF that effects its creations and redemptions only on an in-kind basis. ETFs are able to make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. A fund that effects redemptions for cash may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. Any recognized gain on these sales by the fund will generally cause such fund to recognize a gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities only in-kind. The Fund intends to distribute gains that arise by virtue of creations and redemptions being effectuated in cash to shareholders to avoid being taxed on this gain at the fund level and otherwise comply with special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than if they had made an investment in another ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares principally in-kind, will be passed on to those purchasing and redeeming Creation Units in the form of creation and redemption transaction fees. In addition, these factors may result in wider spreads between the bid and the offered prices of Shares than for ETFs that distribute portfolio securities in-kind. The Fund's use of cash for creations and redemptions could also result in dilution to the Fund and increased transaction costs, which could negatively impact the Fund's ability to achieve its investment objective.

32

Cyber Security Risk. As the use of Internet technology has become more prevalent in the course of business, the investment industry has become more susceptible to potential operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund's digital information systems through "hacking" or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the Fund's third-party service providers, such as its administrator, transfer agent, custodian, or issuers in which the Fund invests, can also subject the Fund to many of the same risks associated with direct cyber security breaches. The Fund has established risk management systems designed to reduce the risks associated with cyber security. However, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

Tax Risk. The Fund intends to elect and to qualify each year to be treated as a RIC under Subchapter M of the Code. However, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund's options strategy, its hedging strategy, the possible application of the "straddle" rules, and various loss limitation provisions of the Code. If, in any year, the Fund fails to qualify as a RIC under the applicable tax laws, the Fund would be taxed as an ordinary corporation. Certain options on an ETF may not qualify as "Section 1256 contracts" under Section 1256 of the Code, and disposition of such options will likely result in short-term capital gains or losses. The Fund intends to treat any income it may derive from the FLEX Options as "qualifying income" under the provisions of the Code applicable to RICs. In addition, based upon language in the legislative history, the Fund intends to treat the issuer of the FLEX Options as the referenced asset, which, assuming the referenced asset qualifies as a RIC, would allow the Fund to qualify for special rules in the RIC diversification requirements. If the income is not qualifying income or the issuer of the FLEX Options is not appropriately the referenced asset, the Fund could lose its own status as a RIC. In the event that a shareholder purchases Shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Non-Principal Risks

Inflation Risk. Inflation may reduce the intrinsic value of increases in the value of the Fund. 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. As inflation increases, the value of the Fund's assets can decline as can the value of the Fund's distributions.

33

Legislation and Litigation Risk. Legislation or litigation that affects the value of securities held by the Fund or the Underlying ETF may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain securities. In addition, litigation regarding any of the securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Security Issuer Risk. Issuer-specific attributes may cause a security held by the Fund or the Underlying ETF to be more volatile than the market generally. 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.

Management of the Fund

The Fund is a series of Innovator ETFs Trust, an investment company registered under the 1940 Act. The Fund is treated as a separate fund with its own investment objectives and policies. The Trust is organized as a Delaware statutory trust. The Board is responsible for the overall management and direction of the Trust. The Board elects the Trust's officers and approves all significant agreements, including those with the Adviser, Sub-Adviser, custodian and fund administrative and accounting agent.

Investment Adviser

Innovator Capital Management, LLC, 109 North Hale Street, Wheaton, Illinois 60187, serves as the Fund's investment adviser. In its capacity as Adviser, Innovator has overall responsibility for selecting and monitoring the Fund's investments and managing the Fund's business affairs.

Investment Sub-Adviser

Milliman Financial Risk Management LLC, 71 South Wacker Drive, 31st Floor, Chicago, Illinois 60606, serves as the Fund's investment sub-adviser. Milliman has responsibility for managing the Fund's investment program in pursuit of its investment objective.

Portfolio Managers

Robert T. Cummings and Yin Bhuyan serve as the Fund's portfolio managers.

Robert T. Cummings, Principal and Director of Global Trading at Milliman. Mr. Cummings has served in this role since 2007. Mr. Cummings has more than 13 years of experience as a trader with a primary focus on options.

Yin Bhuyan, Associate - ETF Portfolio Management Team at Milliman. Ms. Bhuyan has more than 10 years of experience in capital markets. Prior to joining Milliman, Yin traded in the S&P options pit at CBOE. She has served both as a market maker and a portfolio manager. Her former experience is in risk management and volatility arbitrage. Yin's current primary focus had been in managing Defined Outcome ETFs and Index tracking ETFs.

For additional information concerning Innovator and Milliman, including a description of the services provided to the Fund, please see the Fund's SAI. Additional information regarding the portfolio managers' compensation, other accounts managed by the portfolio managers and the portfolio managers' ownership of Shares may also be found in the SAI.

Management Fee

Pursuant to an investment advisory agreement between Innovator and the Trust, on behalf of the Fund (the "Investment Management Agreement"), the Fund has agreed to pay an annual unitary management fee to Innovator in an amount equal to 0.89% of its average daily net assets. This unitary management fee is designed to pay the Fund's expenses and to compensate Innovator for the services it provides to the Fund. Out of the unitary management fee, Innovator pays substantially all expenses of the Fund, including the cost of transfer agency, custody, fund administration, legal, audit and other service and license fees. However, Innovator is not responsible for distribution and service fees payable pursuant to a Rule 12b-1 plan, if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, taxes, interest, and extraordinary expenses.

36

Pursuant to an investment sub-advisory agreement between Innovator, Milliman and the Trust, on behalf of the Fund (the "Investment Sub-Advisory Agreement"), Innovator has agreed to pay an annual sub-advisory fee to Milliman in an amount based on the Fund's average daily net assets. Innovator is responsible for paying the entirety of Milliman's sub-advisory fee. The Fund does not directly pay Milliman.

A discussion regarding the basis for the Board's approval of the Investment Management Agreement and Investment Sub-Advisory Agreement on behalf of the Fund is available in the Fund's Annual Report to shareholders for the fiscal year ended October 31, 2021.

Manager of Managers Structure. The Fund and Innovator have received an exemptive order from the SEC to operate under a manager of managers structure that permits Innovator, with the approval of the Board, to appoint and replace sub-advisers, enter into sub-advisory agreements, and materially amend and terminate sub-advisory agreements on behalf of the Fund without shareholder approval ("Manager of Managers Structure"). Under the Manager of Managers Structure, Innovator has ultimate responsibility, subject to oversight by the Board, for overseeing the Fund's sub-advisers and recommending to the Board their hiring, termination, or replacement. The SEC order does not apply to any sub-adviser that is affiliated with the Fund or Innovator.

The Manager of Managers Structure enables the Fund to operate with greater efficiency and without incurring the expense and delays associated with obtaining shareholder approvals for matters relating to the Sub-Adviser or the Investment Sub-Advisory Agreement. The Manager of Managers Structure does not permit an increase in the advisory fees payable by the Fund without shareholder approval. Shareholders will be notified of any changes made to the Sub-Adviser or the Investment Sub-Advisory Agreement within 90 days of the change.

How to Buy and Sell Shares

The Fund will issue or redeem its Shares at NAV per Share only in Creation Units. Most Fund shareholders will buy and sell Shares in secondary market transactions through brokers. Shares will be listed for trading on the secondary market on the Exchange. Shares can be bought and sold throughout the trading day like other publicly traded shares. Share prices are reported in dollars and cents per Share. There is no minimum investment. When buying or selling Shares through a broker, you will incur customary brokerage commissions and charges, and you may pay some or all of the spread between the bid and the offered price in the secondary market on each leg of a round trip (purchase and sale) transaction. Because Shares trade at market price rather than NAV, a Fund shareholder may pay more than NAV when purchasing Shares and receive less than NAV when selling Shares.

37

APs may acquire Shares directly from the Fund, and APs may tender their Shares for redemption directly to the Fund, at NAV per Share only in Creation Units, and in accordance with the procedures described in the SAI.

BookEntry

Shares are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company ("DTC") or its nominee is the record owner of all outstanding Shares and is recognized as the owner of all Shares for all purposes.

Investors owning Shares are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for all Shares. Participants in DTC include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of Shares, you are not entitled to receive physical delivery of stock certificates or to have Shares registered in your name, and you are not considered a registered owner of Shares. Therefore, to exercise any right as an owner of Shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other stocks that you hold in book entry or "street name" form.

Share Trading Prices

The trading prices of Shares on the Exchange is based on market price and may differ from the Fund's daily NAV. Market forces of supply and demand, economic conditions and other factors may affect the trading prices of Shares.

Frequent Purchases and Redemptions of Shares

Shares may be purchased and redeemed directly from the Fund only in Creation Units by APs that have entered into agreements with the Fund's distributor. The vast majority of trading in Shares occurs on the secondary market and does not involve the Fund directly. Cash trades on the secondary market are unlikely to cause many of the harmful effects of frequent purchases and/or redemptions of Shares. Cash purchases and/or redemptions of Creation Units, however, can result in disruption of portfolio management, dilution to the Fund and increased transaction costs, which could negatively impact the Fund's ability to achieve its investment objectives, and may lead to the realization of capital gains. These consequences may increase as the frequency of cash purchases and redemptions of Creation Units by APs increases. However, direct trading by APs is critical to ensuring that Shares trade at or close to NAV.

To minimize these potential consequences of frequent purchases and redemptions of Shares, the Fund imposes transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs the Fund incurs in effecting trades. In addition, the Fund reserves the right to not accept orders from APs that Innovator has determined may be disruptive to the management of the Fund or otherwise are not in the best interests of the Fund. For these reasons, the Board has not adopted policies and procedures with respect to frequent purchases and redemptions of Shares.

38

Dividends, Distributions and Taxes

Ordinarily, dividends from net investment income, if any, are declared and paid at least annually by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders annually.

Distributions in cash may be reinvested automatically in additional whole Shares only if the broker through whom you purchased Shares makes such option available.

Taxes

This section summarizes some of the main U.S. federal income tax consequences of owning Shares of the Fund. This section is current as of the date of this prospectus. Tax laws and interpretations change frequently, and these summaries do not describe all of the tax consequences to all taxpayers. For example, these summaries generally do not describe your situation if you are a corporation, a non-U.S. person, a broker-dealer, or other investor with special circumstances. In addition, this section does not describe your state, local or non-U.S. tax consequences.

This federal income tax summary is based in part on the advice of counsel to the Fund. The Internal Revenue Service could disagree with any conclusions set forth in this section. In addition, counsel to the Fund was not asked to review, and has not reached a conclusion with respect to, the federal income tax treatment of the assets to be included in the Fund. This may not be sufficient for you to use as the purpose of avoiding penalties under federal tax law.

As with any investment, you should seek advice based on your individual circumstances from your own tax advisor.

The Fund intends to continue to qualify as a "regulated investment company" under the federal tax laws. If the Fund qualifies as a regulated investment company and distributes its income as required by the tax law, the Fund generally will not pay federal income taxes.

As with any investment, you should consider how your investment in Shares will be taxed. The tax information in this prospectus is provided as general information. You should consult your own tax professional about the tax consequences of an investment in Shares.

Unless your investment in Shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA plan, you need to be aware of the possible tax consequences when:

• Your Fund makes distributions,

• You sell your Shares listed on the Exchange, and

• You purchase or redeem Creation Units.

To maintain its status as a RIC, the Fund must meet certain income, diversification and distributions tests. The Fund intends to treat any income that it may derive from the FLEX Options as "qualifying income" under the provisions of the Code applicable to RICs. In addition, based upon language in the legislative history, the Fund intends to treat the issuer of the FLEX Options as the referenced asset, which, assuming the referenced asset qualifies as a RIC, would allow the Fund to qualify for special rules in the RIC diversification requirements. If the income is not qualifying income or the issuer of the FLEX Options is not appropriately the referenced asset, the Fund could lose its own status as a RIC.

39

Taxes on Distributions

The Fund's distributions are generally taxable. After the end of each year, you will receive a tax statement that separates the distributions of the Fund into two categories, ordinary income distributions and capital gain dividends. Ordinary income distributions are generally taxed at your ordinary tax rate; however, certain ordinary income distributions received from the Fund may be taxed at the capital gains tax rates. Generally, you will treat all capital gain dividends as long-term capital gains regardless of how long you have owned your Shares. To determine your actual tax liability for your capital gain dividends, you must calculate your total net capital gain or loss for the tax year after considering all of your other taxable transactions, as described below. In addition, the Fund may make distributions that represent a return of capital for tax purposes and thus will generally not be taxable to you; however, such distributions may reduce your tax basis in your Shares, which could result in you having to pay higher taxes in the future when Shares are sold, even if you sell the Shares at a loss from your original investment. The tax status of your distributions from the Fund is not affected by whether you reinvest your distributions in additional Shares or receive them in cash. The income from the Fund that you must take into account for federal income tax purposes is not reduced by amounts used to pay a deferred sales fee, if any. The tax laws may require you to treat distributions made to you in January as if you had received them on December 31 of the previous year.

Income from the Fund may also be subject to a 3.8% "Medicare tax." This tax generally applies to your net investment income if your adjusted gross income exceeds certain threshold amounts, which are $250,000 in the case of married couples filing joint returns and $200,000 in the case of single individuals.

A corporation that owns Shares generally will not be entitled to the dividends received deduction with respect to many dividends received from the Fund because the dividends received deduction is generally not available for distributions from regulated investment companies.

If you are an individual, the maximum marginal stated federal tax rate for net capital gain is generally 20% (15% or 0% for taxpayers with taxable incomes below certain thresholds). Capital gains may also be subject to the Medicare tax described above.

Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than one year and is short-term if the holding period for the asset is one year or less. You must exclude the date you purchase your Shares to determine your holding period. However, if you receive a capital gain dividend from the Fund and sell your Shares at a loss after holding it for six months or less, the loss will be recharacterized as long-term capital loss to the extent of the capital gain dividend received. The tax rates for capital gains realized from assets held for one year or less are generally the same as for ordinary income. The Code treats certain capital gains as ordinary income in special situations.

An election may be available to shareholders to defer recognition of the gain attributable to a capital gain dividend if they make certain qualifying investments within a limited time. Shareholders should talk to their tax advisor about the availability of this deferral election and its requirements.

40

Taxes on Exchange Listed Shares

If you sell or redeem your Shares, you will generally recognize a taxable gain or loss. To determine the amount of this gain or loss, you must subtract your tax basis in your Shares from the amount you receive in the transaction. Your tax basis in your Shares is generally equal to the cost of your Shares, generally including sales charges. In some cases, however, you may have to adjust your tax basis after you purchase your Shares.

Taxes and Purchases and Redemptions of Creation Units

If you exchange securities for Creation Units you will generally recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and your aggregate basis in the securities surrendered and the cash component paid. If you exchange Creation Units for securities, you will generally recognize a gain or loss equal to the difference between your basis in the Creation Units and the aggregate market value of the securities received and any cash redemption amount. The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for Creation Units or Creation Units for securities cannot be deducted currently under the rules governing "wash sales," or on the basis that there has been no significant change in economic position.

Treatment of the FLEX Options

The Fund's investments in offsetting positions with respect to the Underlying ETF may be "straddles" for U.S. federal income tax purposes. The straddle rules may affect the character of gains (or losses) realized by the Fund, and losses realized by the Fund on positions that are part of a straddle may be deferred under the straddle rules, rather than being taken into account in calculating taxable income for the taxable year in which the losses are realized. In addition, certain carrying charges (including interest expense) associated with positions in a straddle may be required to be capitalized rather than deducted currently. Certain elections that the Fund may make with respect to its straddle positions may also affect the amount, character and timing of the recognition of gains or losses from the affected positions.

The tax consequences of straddle transactions to the Fund are not entirely clear in all situations under currently available authority. The straddle rules may increase the amount of short-term capital gain realized by the Fund, which is taxed as ordinary income when distributed to U.S. shareholders in a non-liquidating distribution. Because application of the straddle rules may affect the character of gains or losses, defer losses and/or accelerate the recognition of gains or losses from the affected straddle positions, if the Fund makes a non-liquidating distribution of its short-term capital gain, the amount which must be distributed to U.S. shareholders as ordinary income may be increased or decreased substantially as compared to a fund that did not engage in such transactions.

The FLEX Options included in the portfolio are exchange-traded options. Under Section 1256 of the Code, certain types of exchange-traded options are treated as if they were sold (i.e., "marked to market") at the end of each year. The Fund does not believe that the positions held by the Fund will be subject to Section 1256, which means that the positions will not be marked to market, but the positions will be subject to the straddle rules.

41

Treatment of Fund Expenses

Expenses incurred and deducted by the Fund will generally not be treated as income taxable to you. In some cases, however, you may be required to treat your portion of these Fund expenses as income. You may not be able to take a deduction for some or all of these expenses, even if the cash you receive is reduced by such expenses.

Backup Withholding

The Fund may be required to withhold U.S. federal income tax ("backup withholding") from dividends and capital gains distributions paid to Shareholders. Federal tax will be withheld if (1) the Shareholder fails to furnish the Fund with the Shareholder's correct taxpayer identification number or social security number, (2) the IRS notifies the Shareholder or the Fund that the Shareholder has failed to report properly certain interest and dividend income to the IRS and to respond to notices to that effect, or (3) when required to do so, the Shareholder fails to certify to the Fund that he or she is not subject to backup withholding. The current backup withholding rate is 24%. Any amounts withheld under the backup withholding rules may be credited against the Shareholder's U.S. federal income tax liability.

Non-U.S. Investors

If you are a non-U.S. investor (i.e., an investor other than a U.S. citizen or resident or a U.S. corporation, partnership, estate or trust), you should be aware that, generally, subject to applicable tax treaties, distributions from the Fund will generally be characterized as dividends for U.S. federal income tax purposes (other than dividends which the Fund properly reports as capital gain dividends) and will be subject to U.S. federal income taxes, including withholding taxes, subject to certain exceptions described below.

However, distributions received by a non-U.S. investor from the Fund that are properly reported by the Fund as capital gain dividends may not be subject to U.S. federal income taxes, including withholding taxes, provided that the Fund makes certain elections and certain other conditions are met. Distributions from the Fund that are properly reported by the Fund as an interest-related dividend attributable to certain interest income received by the Fund or as a short-term capital gain dividend attributable to certain net short-term capital gain income received by the Fund may not be subject to U.S. federal income taxes, including withholding taxes when received by certain non-U.S. investors, provided that the Fund makes certain elections and certain other conditions are met.

Distributions to, and gross proceeds from dispositions of Shares by, (i) certain non-U.S. financial institutions that have not entered into an agreement with the U.S. Treasury to collect and disclose certain information and are not resident in a jurisdiction that has entered into such an agreement with the U.S. Treasury and (ii) certain other non-U.S. entities that do not provide certain certifications and information about the entity's U.S. owners may be subject to a U.S. withholding tax of 30%. However, proposed regulations may eliminate the requirement to withhold on payments of gross proceeds from dispositions.

The foregoing discussion summarizes some of the possible consequences under current federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You also may be subject to state and local taxes on Fund distributions and sales of Shares.

Consult your personal tax advisor about the potential tax consequences of an investment in Shares under all applicable tax laws. See "Distributions and Taxes" in the SAI for more information.

42

Distributor

Foreside Fund Services, LLC serves as the distributor of Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in Shares.

Net Asset Value

US Bancorp Fund Services LLC ("USBFS"), the Fund's administrator and fund accounting agent, calculates the Fund's NAV at the close of regular trading (ordinarily 4:00 p.m. E.S.T.) every day the New York Stock Exchange is open. The NAV for one Share is the value of that Share's portion of all of the net assets of the Fund. In calculating NAV, the Fund generally values its investment portfolio at market price.

FLEX Options listed on an exchange (e.g., NYSE Arca) will typically be valued at a model-based price provided by the exchange at the official close of that exchange's trading day. However, when the Fund's option has a same-day market trading price, this same-day market trading price will be used for FLEX Option values instead of the exchange's model-based price. If the exchange on which the option is traded is unable to provide a model price, model-based FLEX Options prices will additionally be provided by a backup third-party pricing provider. In selecting the model prices, the Sub-Adviser may provide a review of the calculation of model prices provided by each vendor, and may note to such vendors of any data errors observed, or where an underlying component value of the model pricing package may be missing or incorrect, prior to publication by the vendor of the model pricing to the Fund Accounting Agent for purposes of that day's NAV. If either pricing vendor is not available to provide a model price for that day, the value of a FLEX option will be determined by the Pricing Committee (as defined below) in accordance with the Valuation Procedures (as defined below). In instances where in the same trading day, a particular FLEX Option is represented in an all-cash basket (either a creation unit or redemption unit), as well as in an in-kind basket (either a creation unit or a redemption unit), for valuation purposes that trading day the Fund will default to use the trade price for both instances, rather than the model price otherwise available for the in-kind transaction.

Common stocks, preferred stocks and other equity securities listed on any national or foreign exchange (excluding the NASDAQ National Market ("NASDAQ") and the London Stock Exchange Alternative Investment Market ("AIM")) will be valued at the last sale price on the exchange on which they are principally traded or, for NASDAQ and AIM securities, the official closing price. Securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, at the close of the exchange representing the principal market for such securities. Securities traded in the over-the-counter market are valued at the mean of the bid and the asked price, if available, and otherwise at their closing bid price.

Exchange-traded options (other than FLEX Options) and futures contracts will be valued at the closing price in the market where such contracts are principally traded. If no closing price is available, they will be fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. OTC options and futures contracts are fair valued at the mean of the most recent bid and asked price, if available, and otherwise at their closing bid price.

43

USBFS may obtain all market quotations used in valuing securities from a third-party pricing service vendor (a "Pricing Service"). If no quotation can be obtained from a Pricing Service, then USBFS will contact the Trust's pricing committee (the "Pricing Committee"). The Pricing Committee is responsible for establishing the valuation of portfolio securities and other instruments held by the Fund in accordance with the pricing and valuation procedures adopted by the Board (the "Valuation Procedures"). The Pricing Committee will then attempt to obtain one or more broker quotes for the security daily and will value the security accordingly.

If no quotation is available from either a Pricing Service, or one or more brokers, or if the Pricing Committee has reason to question the reliability or accuracy of a quotation supplied or the use of amortized cost, the value of any portfolio security held by the Fund for which reliable market quotations are not readily available will be determined by the Pricing Committee in a manner that most appropriately reflects fair market value of the security on the valuation date. The use of a fair valuation method may be appropriate if, for example: (i) market quotations do not accurately reflect fair value of an investment; (ii) an investment's value has been materially affected by events occurring after the close of the exchange or market on which the investment is principally traded (for example, a foreign exchange or market); (iii) a trading halt closes an exchange or market early; or (iv) other events result in an exchange or market delaying its normal close.

Fair valuation of an equity security will be based on the consideration of all available information, including, but not limited to, the following: (a) the type of security; (b) the size of the holding; (c) the initial cost of the security; (d) transactions in comparable securities; (e) price quotes from dealers and/or pricing services; (f) relationships among various securities; (g) information obtained by contacting the issuer, analysts, or the appropriate stock exchange; (h) an analysis of the issuer's financial statements; and (i) the existence of merger proposals or tender offers that might affect the value of the security.

With respect to any non-U.S. securities held by the Fund, the Fund may take factors influencing specific markets or issuers into consideration in determining the fair value of a non-U.S. security. International securities markets may be open on days when the U.S. markets are closed. In such cases, the value of any international securities owned by the Fund may be significantly affected on days when investors cannot buy or sell Shares. In addition, due to the difference in times between the close of the international markets and the time the Fund prices its Shares, the value the Fund assigns to securities generally will not be the same as the quoted or published prices of those securities on their primary markets or exchanges. In determining fair value prices, the Fund may consider the performance of securities on their primary exchanges, foreign currency appreciation/depreciation, securities market movements in the U.S., or other relevant information as related to the securities.

For more information about how the Fund's NAV is determined, please see the section in the statement of information entitled "Determination of Net Asset Value."

Investments by Other Investment Companies
