Exchange:	Cboe BZX

FT Vest U.S. Equity Moderate Buffer ETF – October (the “Fund”) lists and principally trades its shares on the Cboe BZX Exchange, Inc. (“Cboe BZX” or the “Exchange”). Market prices may differ to some degree from the net asset value of the shares. Unlike mutual funds, the Fund issues and redeems shares at net asset value, only in large blocks of shares called "Creation Units."

The Fund is a series of First Trust Exchange-Traded Fund VIII (the “Trust”) and an actively-managed exchange-traded fund organized as a separate series of a registered management investment company.

Except when aggregated in Creation Units, the shares are not redeemable securities of the Fund.

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

The Fund is designed to participate in the positive price returns (before fees and expenses) of the State Street® SPDR® S&P 500® ETF Trust (the “Underlying ETF”) up to a cap of 14.05%, while seeking to provide a buffer (before fees and expenses) against the first 15% of Underlying ETF losses over the period from October 19, 2026 through October 15, 2027 (the “Target Outcome Period”). When the Fund's fees and expenses are taken into account, the cap is 13.20% and the buffer is 14.15%. The cap and buffer will be further reduced by any brokerage commissions, trading fees, taxes and extraordinary expenses not included in the Fund's management fee. At the end of the Target Outcome Period, the Fund will reset for a new Target Outcome Period tied to the same Underlying ETF and buffer, but the cap may change based on market rates as of the start of the new Target Outcome Period.

The Fund has characteristics unlike many other typical investment products and may not be suitable for all investors. It is important that investors understand the Fund’s investment strategy before making an investment in the Fund.

The outcomes described in this prospectus are specifically designed to apply only if you buy shares on the first day of the Target Outcome Period and continue to hold them on the last day of the period. If you purchase shares after the Target Outcome Period starts or sell your shares before the Target Outcome Period ends, you may receive a very different return based on the Fund’s current value.

Summary Information

FT Vest U.S. Equity Moderate Buffer ETF – October (GOCT)

Investment Objective

The investment objective of the FT Vest U.S. Equity Moderate Buffer ETF – October (the “Fund”) is to seek to provide investors with returns (before fees and expenses) that match the price return of the State Street® SPDR® S&P 500® ETF Trust (the “Underlying ETF”), up to a predetermined upside cap of 14.05% while providing a buffer (before fees and expenses) against the first 15% of Underlying ETF losses, over the period from October 19, 2026 through October 15, 2027.

Fees and Expenses of the Fund

The following table describes the fees and expenses you may pay if you buy, hold and sell shares of the Fund. Investors may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

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

Management Fees	0.85%
Distribution and Service (12b-1) Fees	0.00%
Other Expenses	0.00%
Total Annual Fund Operating Expenses	0.85%

Example

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

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then hold or 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. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$87	$271	$471	$1,049

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 0% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund will invest substantially all of its assets in FLexible EXchange® Options (“FLEX Options”) that reference the price performance of the State Street® SPDR® S&P 500® ETF Trust (the “Underlying ETF”). FLEX Options are customized equity or index option contracts that trade on an exchange, but provide investors with the ability to customize key contract terms like exercise prices, styles and expiration dates. The Underlying ETF is an exchange-traded unit investment trust that uses a replication strategy, meaning it invests in as many of the stocks in the S&P 500® Index as is practicable. PDR Services, LLC ("PDR") serves as the Underlying ETF’s sponsor. The investment objective of the Underlying ETF is to seek to provide investment results that, before expenses, correspond generally to the price and yield performance of the S&P 500® Index. The Fund's performance will not reflect the payment of dividends by the Underlying ETF. See “The Underlying ETF” for more information. The Fund’s investment sub-advisor is Vest Financial LLC ("Vest" or the "Sub-Advisor").

The Fund uses FLEX Options to employ a “target outcome strategy.” Target 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 a buffer (before fees and expenses) against the first 15% of Underlying ETF losses and a cap of 14.05% (before fees and expenses), are based on the price performance of the Underlying ETF over an approximate one-year period (the “Target Outcome Period”). When the Fund's fees and expenses are taken into account, the cap is 13.20% and the

buffer is 14.15%. The cap and buffer will be further reduced by any brokerage commissions, trading fees, taxes and extraordinary expenses not included in the Fund's management fee. The target outcomes the Fund seeks for investors that hold Fund shares for an entire Target Outcome Period are as follows, though there can be no guarantee these results will be achieved:

●

If the Underlying ETF appreciates over the Target Outcome Period, the combination of FLEX Options held by the Fund seeks to provide upside participation matching the performance of the share price of the Underlying ETF, up to a cap that is determined at the start of the Target Outcome Period. The cap for the current Target Outcome Period is 14.05%, prior to taking into account the Fund’s fees and expenses.

●

If the Underlying ETF decreases over the Target Outcome Period, the combination of FLEX Options held by the Fund seeks to provide protection of the first 15% of Underlying ETF losses, prior to taking into account the Fund's fees and expenses.

●

If the Underlying ETF decreases in price by more than 15% over the Target Outcome Period, the Fund will experience all subsequent losses on a one-to-one basis (i.e., if the Underlying ETF loses 20%, the Fund loses 5% (before fees and expenses)).

See the bar chart and line graph set forth in the section entitled "Buffer and Cap" for more information.

The current Target Outcome Period will begin on October 19, 2026 and end on October 15, 2027. Subsequent Target Outcome Periods will begin on the day the prior Target Outcome Period ends and will end on the approximate one-year anniversary of that new Target Outcome Period. On the first day of each new Target Outcome Period, the Fund resets by investing in a new set of FLEX Options that are designed to provide a new cap for the new Target Outcome Period. This means that the cap will change for each Target Outcome Period based upon prevailing market conditions at the beginning of each Target Outcome Period. The buffer will remain the same for each Target Outcome Period. The cap and buffer, and the Fund’s value relative to each, should be considered before investing in the Fund. The Fund will be perpetually offered and not terminate after the current or any subsequent Target Outcome Period. Approximately one week prior to the end of the current Target Outcome Period, the Fund’s website will be updated to alert existing shareholders that the Target Outcome Period is approaching its conclusion and will disclose the anticipated cap range for the next Target Outcome Period. There is no guarantee that the final cap set for a Target Outcome Period will be within the anticipated cap range. See "Subsequent Target Outcome Periods" for more information.

An investor that purchases Fund shares other than on the first day of a Target Outcome Period and/or sells Fund shares prior to the end of a Target Outcome Period may experience results that are very different from the target outcomes sought by the Fund for that Target Outcome Period. While the cap and buffer are designed to provide the intended outcomes only for investors that hold their shares throughout the complete term of the Target Outcome Period, an investor can expect their shares to generally move in the same direction as the Underlying ETF during the Target Outcome Period. However, during the Target Outcome Period, an investor’s shares may not experience price movement to the same extent as the price movement of the Underlying ETF. During the Target Outcome Period, there may be periods of significant disparity between the Fund’s NAV and the Underlying ETF’s price performance. As the Underlying ETF price and the Fund’s Net Asset Value (“NAV”) change over the Target Outcome Period, an investor acquiring Fund shares after the start of the Target Outcome Period will likely have a different return potential than an investor who purchased Fund shares at the start of the Target Outcome Period. This is because while the cap and buffer for the Target Outcome Period are fixed levels that are calculated in relation to the Underlying ETF price and the Fund's NAV at the start of a Target Outcome Period and remain constant throughout the Target Outcome Period, an investor purchasing Fund shares at market value during the Target Outcome Period likely purchased Fund shares at a price that is different from the Fund’s NAV at the start of the Target Outcome Period (i.e., the NAV that the cap and buffer reference). For example, if an investor purchases Fund shares during a Target Outcome Period at a time when the Fund has decreased in value from the value of the Fund on the first day of the Target Outcome Period, that investor’s buffer will essentially be decreased by the amount of the decrease in the Underlying ETF value. Conversely, if an investor purchases Fund shares during a Target Outcome Period at a time when the Fund has increased in value from the value of the Fund on the first day of the Target Outcome Period, that investor’s cap will essentially be decreased by the amount of the increase in the Underlying ETF’s value. See “Buffer and Cap” below for additional information. To achieve the target outcomes sought by the Fund for a Target Outcome Period, an investor must hold Fund shares for that entire Target Outcome Period. An investor that holds Fund shares through multiple Target Outcome Periods may fail to experience gains comparable to those of the Underlying ETF over time because at the end of each Target Outcome Period, a new cap will be established based on the then current price of the Underlying ETF and any gains above the prior cap will be forfeit. Similarly, an investor that holds Fund shares through multiple Target Outcome Periods will be unable to recapture losses from prior Target Outcome Periods because at the end of each Target Outcome Period, a new buffer will be established based on the then current price of the Underlying

ETF and any losses experienced below the prior buffer will be locked in. Moreover, the annual imposition of a new cap on future gains may make it difficult to recoup any losses from prior Target Outcome Periods such that, over multiple Target Outcome Periods, the Fund may have losses that exceed those of the Underlying ETF.

Buffer and Cap

The Fund seeks to provide a buffer on the first 15% loss of the Underlying ETF at the end of each Target Outcome Period. After the Underlying ETF has decreased in price by more than 15%, the Fund will experience subsequent losses on a one-to-one basis (i.e., if the Underlying ETF loses 20%, the Fund loses 5% (before fees and expenses)). The buffer is before taking into account the Fund’s fees and expenses charged to shareholders. When the Fund's fees and expenses are taken into account, the buffer is 14.15%. The buffer will be further reduced by any brokerage commissions, trading fees, taxes and extraordinary expenses not included in the Fund's management fee. The Fund does not seek to provide a buffer on the first 15% loss of the Underlying ETF at any time other than the end of the Target Outcome Period.

If an investor purchases Fund shares during a Target Outcome Period at a time when the Fund has decreased in value by 15% or more from the value of the Fund on the first day of the Target Outcome Period (the “Initial Fund Value”), that investor’s buffer will essentially be zero (meaning the investor can lose its entire investment). If an investor purchases Fund shares at a time when the Fund has decreased in value by less than 15% from the Initial Fund Value, that investor’s buffer will be reduced by the difference between the Initial Fund Value and the NAV of the Fund on the date the investor purchases the shares. However, that investor’s potential gain will be larger than the Fund’s cap for the Target Outcome Period because the investor may experience the full gain if the Fund recovers the value it has lost from the first day of the Target Outcome Period through the date the investor purchased its Fund shares plus any additional gains between the Initial Fund Value and the cap. The cap and buffer relative to the Initial Fund Value, however, will not change over the Target Outcome Period.

Conversely, if an investor purchases Fund shares during a Target Outcome Period at a time when the Fund has increased in value from its Initial Fund Value for a Target Outcome Period, then that investor's cap will essentially be decreased by the amount of increase in the Fund's value from the Initial Fund Value, and the investor will experience losses prior to gaining the protection offered by the buffer (because the Fund must first decrease in value to its Initial Fund Value for the Target Outcome Period before subsequent losses will be protected by the buffer). While the Fund seeks to limit losses to 85% for shareholders who hold Fund shares for an entire Target Outcome Period, there is no guarantee it will successfully do so. Depending on the Fund's NAV at the time of purchase, a shareholder that purchases Fund shares after the first day of a Target Outcome Period may lose their entire investment if the Fund has decreased in value below the buffer. An investment in the Fund is only appropriate for shareholders willing to bear those losses. Despite the intended buffer, a shareholder could lose their entire investment.

The returns of the Fund are subject to a cap of 14.05% (before fees and expenses) and 13.20% (after fees and expenses, excluding brokerage commissions, trading fees, taxes and extraordinary expenses not included in the Fund’s management fee) for the Target Outcome Period. Unlike other investment products, the potential returns an investor can receive from the Fund are subject to a pre-determined upside return cap that represents the maximum percentage return an investor can achieve from an investment in the Fund for an entire Target Outcome Period (before fees and expenses). In the event the Underlying ETF experiences gains over a Target Outcome Period, the Fund seeks to provide investment returns before fees and expenses that match the percentage increase of the Underlying ETF, but any percentage gains over amount of the cap will not be experienced by the Fund. This means that if the Underlying ETF experiences gains for a Target Outcome Period in excess of the cap for that Target Outcome Period, the Fund will not benefit from those excess gains. Therefore, regardless of the performance of the Underlying ETF, the cap is the maximum return an investor can achieve from an investment in the Fund for that Target Outcome Period.

The cap is set on the first day of each Target Outcome Period. The cap is provided prior to taking into account annual Fund management fees of 0.85% of the Fund's daily net assets, brokerage commissions, trading fees, taxes and any extraordinary expenses incurred by the Fund. Such extraordinary expenses (incurred outside of the ordinary operation of the Fund) may include, for example, unexpected litigation, regulatory or tax expenses. The cap and buffer could be lower if the Fund incurs extraordinary expenses or other costs and expenses that are not borne by the Advisor under its unitary management fee. The defined cap applicable to a Target Outcome Period will vary based on prevailing market conditions at the time, including then-current interest rate levels, Underlying ETF volatility, and the relationship of puts and calls on the underlying FLEX Options.

The cap level 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 put and call FLEX Options on the first day of a Target Outcome Period. As the purchaser of these FLEX Options, the Fund is obligated to pay a premium to the seller of those FLEX Options. The portfolio managers will calculate the amount of premiums that the Fund will owe on the put options acquired and sold to provide the buffer and will then go into the market and sell call options with terms that entitle the Fund to receive premiums such that the net amount of premiums paid per unit of the Underlying ETF is approximately equal to the price per unit of shares of the Underlying ETF. The cap is the strike price of those sold FLEX Options.

The cap, and the Fund’s value relative to it on any given day, should be considered before investing in the Fund. If an investor purchases Fund shares during a Target Outcome Period, and the Fund has already increased in value above its Initial Fund Value for that Target Outcome Period to a level near to the cap, an investor purchasing Fund shares will have limited to no gain potential for the remainder of the Target Outcome Period (because the investor’s potential gain will be limited to the difference between the Fund’s NAV on the date the investor purchased the Fund shares and the cap). However, the investor will remain vulnerable to significant downside risk because the investor will bear the losses between the price at which they purchased Fund shares and the Initial Fund Value for the Target Outcome Period before subsequent losses will be protected by the buffer. If an investor buys Fund shares when the price exceeds the cap, an investor will not experience any gain regardless of the performance of the Underlying ETF.

The following bar chart and line graph illustrate the hypothetical returns that the FLEX Options seek to provide with respect to the price performance of the Underlying ETF in certain illustrative scenarios over the course of the Target Outcome Period. The hypothetical cap level in the bar chart and line graph below is for illustration only and the actual cap may be different. The bar chart and line graph do not take into account payment by the Fund of fees and expenses. The bar chart and line graph only provide an example of the Fund’s desired outcomes for investors holding through the entire Target Outcome Period, and are not necessarily indicative of Fund performance. There is no guarantee that the Fund will be successful in providing these investment outcomes for any Target Outcome Period.

Investors purchasing shares of the Fund during a Target Outcome Period will experience different results. The Fund’s website, http://www.ftportfolios.com/retail/etf/EtfSummary.aspx?Ticker=GOCT, provides information relating to the possible outcomes for an investor of an investment in the Fund on a daily basis, if purchased on that date and held through the end of the Target Outcome Period, including the Fund’s value relative to the cap and buffer. Before purchasing Fund shares, an investor should visit the Fund's website to review this information and understand the possible outcomes of an investment in Fund shares on a particular day and held through the end of the Target Outcome Period.

The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund will not invest 25% or more of the value of its total assets in securities of issuers in any one industry or group of industries except to the extent that the Underlying ETF invests more than 25% of its assets in an industry or group of industries.

General Information on the FLEX Options

For each Target Outcome Period, the Fund will invest in both purchased and written put and call FLEX Options that reference the Underlying ETF. Because the value of the Fund is based on FLEX Options that reference the Underlying ETF and not the Underlying ETF directly, variations in the value of the FLEX Options impact the correlation between the Fund’s NAV and the price of the Underlying ETF. FLEX Options are customizable exchange-traded option contracts guaranteed for settlement by the Options Clearing Corporation (“OCC”), a market clearinghouse. The OCC guarantees performance by each of the counterparties to the FLEX Options, becoming the “buyer for every seller and the seller for every buyer,” protecting clearing members and options traders from counterparty risk. The OCC may make adjustments to FLEX Options for certain significant events, as more fully described in the section entitled "Fund Investments" below. Although guaranteed for settlement by the OCC, FLEX Options are still subject to counterparty risk with the OCC and subject to the risk that the OCC may fail to perform the settlement of the FLEX Options due to bankruptcy or other adverse reasons.

The FLEX Options that the Fund will hold that reference the Underlying ETF will give the Fund the right or the obligation to either receive or deliver shares of the Underlying ETF, or the right or the obligation to either receive or deliver a cash payment on the option expiration date based upon the difference between the Underlying ETF’s value and a strike price, depending on whether the option is a put or call option and whether the Fund purchases or sells the option. The FLEX Options held by the Fund are European style options, which are exercisable at the strike price only on the FLEX Option expiration date.

The Fund will generally, under normal conditions, hold four kinds of FLEX Options for each Target Outcome Period. The Fund will purchase call options (giving the Fund the right to receive shares of the Underlying ETF or a cash payment) and put options (giving the Fund the right to deliver shares of the Underlying ETF or a cash payment), while simultaneously selling (i.e., writing) call options (giving the Fund the obligation to deliver shares of the Underlying ETF or a cash payment) and put options (giving the Fund the obligation to receive shares of the Underlying ETF or a cash payment). The Fund intends to structure the FLEX Options so that any amount owed by the Fund on the written FLEX Options will be covered by payouts at expiration from the purchased FLEX Options. As a result, the FLEX Options will be fully covered and no additional collateral will be necessary during the life of the Fund. The Fund receives premiums in exchange for the written FLEX Options and pays premiums in exchange for the purchased FLEX Options. The OCC and securities exchanges on which the FLEX Options are listed do not charge ongoing fees to writers or purchasers of the FLEX Options during their life for continuing to hold the option contracts, but may charge transaction fees. Each of the FLEX Options purchased and sold throughout the Target Outcome Period will have the same terms, such as strike price and expiration date, as the FLEX Options purchased and sold on the first day of the Target Outcome Period.

On the FLEX Options expiration date, the Fund intends to sell the FLEX Options prior to their expiration or cash-settle the FLEX Options and use the resulting proceeds to purchase new FLEX Options for the next Target Outcome Period.

The Underlying ETF

The Underlying ETF is an exchange-traded unit investment trust that uses a replication strategy, meaning it invests in as many of the stocks in the S&P 500® Index as is practicable. PDR Services, LLC ("PDR") serves as the Underlying ETF’s sponsor. The investment objective of the Underlying ETF is to seek to provide investment results that, before expenses, correspond generally to the price and yield performance of the S&P 500® Index (the “Index”). See below for a description of the Underlying ETF’s principal investment strategies and risks. You can find the Underlying ETF’s prospectus and other information about the ETF, including the statement of additional information and most recent reports to shareholders, online at http://www.ssga.com/us/en/intermediary/etfs/state-street-spdr-sp-500-etf-trust-spy.com.

The summary information below regarding the Underlying ETF comes from its filings with the SEC. You are urged to refer to the SEC filings made by the Underlying ETF and to other publicly available information (e.g., the Underlying ETF’s annual reports) to obtain an understanding of the Underlying ETF’s business and financial prospects.

The following description of the Underlying ETF’s principal investment strategies was taken directly from the Underlying ETF’s prospectus, dated January 26, 2026 (“SPY” refers to the Underlying ETF; other defined terms have been modified and are limited to this excerpt).

“SPY seeks to achieve its investment objective by holding a portfolio of the common stocks that are included in the Index (the “Portfolio”), with the weight of each stock in SPY’s Portfolio substantially corresponding to the weight of such stock in the Index.

In SPY’s prospectus, the term “Portfolio Securities” refers to the common stocks that are actually held by SPY and make up SPY’s Portfolio, while the term “Index Securities” refers to the common stocks that are included in the Index, as determined by the index provider, S&P Dow Jones Indices LLC (“S&P”). At any time, SPY’s Portfolio will consist of as many of the Index Securities as is practicable. To maintain the correspondence between the composition and weightings of Portfolio Securities and Index Securities, State Street Global Advisors Trust Company (the “Trustee”), or its parent company, State Street Bank and Trust Company (“SSBT”), adjusts SPY’s Portfolio from time to time to conform to periodic changes made by S&P to the identity and/or relative weightings of Index Securities in the Index. SPY’s Trustee or SSBT aggregates certain of these adjustments and makes changes to SPY’s Portfolio at least monthly, or more frequently in the case of significant changes to the Index.

SPY may pay transaction costs, such as brokerage commissions, when it buys and sells securities (or “turns over” its Portfolio). Such transaction costs may be higher if there are significant rebalancings of Index Securities in the Index, which may also result in higher taxes when SPY’s units are held in a taxable account. These costs, which are not reflected in SPY’s estimated annual Trust ordinary operating expenses, affect SPY’s performance. During the most recent fiscal year, SPY’s

portfolio turnover rate was 3% of the average value of its portfolio. SPY’s portfolio turnover rate does not include securities received or delivered from processing creations or redemptions of SPY’s units. Portfolio turnover will be a function of changes to the Index as well as requirements of SPY’s trust agreement. …

Although SPY may fail to own certain Index Securities at any particular time, SPY generally will be substantially invested in Index Securities, which should result in a close correspondence between the performance of the Index and the performance of SPY. … SPY does not hold or trade futures or swaps and is not a commodity pool. …

The Index includes five hundred (500) selected companies, all of which are listed on national stock exchanges and spans a broad range of major industries. .... Since 1968, the Index has been a component of the U.S. Commerce Department’s list of Leading Indicators that track key sectors of the U.S. economy. Current information regarding the market value of the Index is available from market information services. The Index is determined, comprised and calculated without regard to SPY.”

As of November 28, 2025, the Underlying ETF had significant investments in information technology companies.

Subsequent Target Outcome Periods

The Fund will alert existing shareholders to the new cap at the beginning of each new Target Outcome Period in the following manner:

1. Approximately one week prior to the end of the current Target Outcome Period, the Fund will make a sticker filing that will alert existing shareholders that the Target Outcome Period is approaching its conclusion and disclose the anticipated cap range for the next Target Outcome Period. There is no guarantee that the final cap set for a Target Outcome Period will be within the anticipated cap range. This filing will be mailed to existing shareholders and posted on the Fund's website.

2. Following the close of business on the last day of the Target Outcome Period, the Fund will make a sticker filing that discloses the Fund’s cap for the next Target Outcome Period. This filing will be mailed to existing shareholders and posted on the Fund's website. Investors should monitor the Fund's website, set forth below, for current information on the next Target Outcome Period.

3. On the first day of the new Target Outcome Period, the Fund will file a full prospectus that incorporates the sticker filing from the previous evening which replaces the caps/dates associated with the previous Target Outcome Period with the caps/dates associated with the new Target Outcome Period. Correspondingly, the Fund will file a revised summary prospectus that reflects such changes. This filing will be posted on the Fund's website.

The information referenced above will also be available on the Fund's website at
http://www.ftportfolios.com/retail/etf/EtfSummary.aspx?Ticker=GOCT.

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 objective will be achieved. The order of the below risk factors does not indicate the significance of any particular risk factor.

ABSENCE OF AN ACTIVE MARKET RISK. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares due to a limited number of market makers or authorized participants. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of shares and market makers are under no obligation to make a market in the Fund’s shares. Additionally, only a limited number of institutions act as authorized participants for the Fund and only an authorized participant may engage in creation or redemption transactions directly with the Fund and are not obligated to submit purchase or redemption orders for Creation Units. 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. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the authorized participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which the Fund’s shares are trading on the Exchange, which could result in a decrease in value of the Fund’s shares. This reduced effectiveness could result in Fund shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads for Fund shares.

BUFFERED LOSS RISK. There can be no guarantee that the Fund will be successful in its strategy to buffer against Underlying ETF losses if the Underlying ETF decreases over the Target Outcome Period by 15% or less. A shareholder may lose their entire investment. The Fund’s strategy seeks to deliver returns (before fees and expenses) that match the price return of the Underlying ETF (up to the cap), while limiting downside losses, if shares are bought on the first day of the Target Outcome Period and held until the end of the Target Outcome Period. In the event an investor purchases shares after the first day of the Target Outcome Period or sells shares prior to the end of the Target Outcome Period, the buffer that the Fund seeks to provide may not be available. If an investor purchases Fund shares during a Target Outcome Period at a time when the Fund has decreased in value by 15% or more from the value of the Fund on the first day of the Target Outcome Period (the “Initial Fund Value”), that investor’s buffer will essentially be zero (meaning the investor can lose its entire investment). If an investor purchases Fund shares at a time when the Fund has decreased in value by less than 15% from the Initial Fund Value, that investor’s buffer will be reduced by the difference between the Initial Fund Value and the NAV of the Fund on the date the investor purchases the shares. An investor that holds Fund shares through multiple Target Outcome Periods will be unable to recapture losses from prior Target Outcome Periods because at the end of each Target Outcome Period, a new buffer will be established based on the then current price of the Underlying ETF and any losses experienced below the prior buffer will be locked in.

CAP CHANGE RISK. A new cap is established at the beginning of each Target Outcome Period and is dependent on prevailing market conditions. As a result, the cap may rise or fall from one Target Outcome Period to the next and is unlikely to remain the same for consecutive Target Outcome Periods.

CAPPED UPSIDE RISK. The Fund’s strategy seeks to provide returns (before fees and expenses) that match those of the Underlying ETF for Fund shares purchased on the first day of a Target Outcome Period and held for the entire Target Outcome Period, subject to a pre-determined upside cap. If an investor does not hold its Fund shares for an entire Target Outcome Period, the returns realized by that investor likely will not match those that the Fund seeks to achieve. If the Underlying ETF experiences gains during a Target Outcome Period, the Fund will not participate in those gains beyond the cap. In the event an investor purchases Fund shares after the first day of a Target Outcome Period and the Fund has risen in value to a level near to the cap, there may be little or no ability for that investor to experience an investment gain on their Fund shares (because the investor’s potential gain will be limited to the difference between the Fund’s NAV on the date the investor purchased the Fund shares and the cap), however, the investor will remain vulnerable to downside risks. If an investor buys Fund shares when the price exceeds the cap, an investor will not experience any gain regardless of the performance of the Underlying ETF. An investor that holds Fund shares through multiple Target Outcome Periods may fail to experience gains comparable to those of the Underlying ETF over time because at the end of each Target Outcome Period, a new cap will be established based on the then current price of the Underlying ETF and any gains above the prior cap will be forfeit. Moreover, the annual imposition of a new cap on future gains may make it difficult to recoup any losses from prior Target Outcome Periods such that, over multiple Target Outcome Periods, the Fund may have losses that exceed those of the Underlying ETF.

CASH TRANSACTIONS RISK. The Fund may effect all or a portion of its creations and redemptions for cash rather than in-kind. 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 in-kind. ETFs are able to make in-kind redemptions and 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 the 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 these gains to shareholders to avoid being taxed on this gain at the fund level and otherwise comply with the 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 a different 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 entirely 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 the Fund’s 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.

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its

investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. 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.

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or shares of the Fund in general, may fall in value due to current market conditions. As a means to fight inflation, the Federal Reserve and certain foreign central banks have raised interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including high interest rates, declining valuations and elevated vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among the United States, Israel, Iran, Hamas, Hezbollah and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East, the United States, and other nations. Such events may also disrupt global trade and supply chains, increase sanctions and other governmental actions, and contribute to volatility in oil and natural gas markets. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

CYBER SECURITY RISK. The Fund is susceptible to operational, information security and related 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, any of which could result in a material adverse effect on the Fund or its shareholders. 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. Emerging threats like ransomware or zero-day exploits could also cause disruptions to Fund operations. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, among many other third-party service providers, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Further, errors, misconduct, or compromise of accounts of employees of the Fund or its third-party service providers can also create material cybersecurity risks. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, 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. Cyber security incidents may also trigger Fund obligations under data privacy

laws, potentially increasing notification and compliance burdens. Cyber security incidents affecting issuers in whose securities the Fund invests may also have a negative impact on the value of the securities of such issuers, and in turn, the value of the Fund.

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience substantial downside from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection may impact the value of the Fund and whether the Fund can satisfy its investment objective. Additionally, 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. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

FLEX OPTIONS VALUATION RISK. The FLEX Options held by the Fund will be exercisable at the strike price only on their expiration date. Prior to the expiration date, the value of the FLEX Options will be determined based upon market quotations or using other recognized pricing methods. The FLEX Options are also subject to correlation risk, meaning the value of the FLEX Options does not increase or decrease at the same rate as the Underlying ETF (although they generally move in the same direction) or its underlying securities. The value of the FLEX Options prior to the expiration date may vary because of factors other than the value of the Underlying ETF, such as interest rate changes, changing supply and demand, decreased liquidity of the FLEX Options, a change in the actual and perceived volatility of the stock market and the Underlying ETF and the remaining time to expiration. FLEX Option prices may also be highly volatile and may fluctuate substantially during a short period of time. 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 approved by the Board of Trustees of the Trust) 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. Under those circumstances, the value of the FLEX Options will require more reliance on the investment adviser’s judgment than that required for securities for which there is an active trading market. This creates a risk of mispricing or improper valuation of the FLEX Options which could impact the value paid for shares of the Fund.

INDEX OR MODEL CONSTITUENT RISK. The Fund may be a constituent of one or more indices or ETF models. As a result, the Fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving the Fund’s shares, the size of the Fund and the market volatility of the Fund. Inclusion in an index could increase demand for the Fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result, the Fund’s net asset value could be negatively impacted and the Fund’s market price may be below the Fund’s net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity in the Fund's shares.

LARGE CAPITALIZATION COMPANIES RISK. The Underlying ETF invests in the securities of large capitalization companies. Large capitalization companies may grow at a slower rate and be less able to adapt to changing market conditions than smaller capitalization companies. Thus, the return on investment in securities of large capitalization companies may be less than the return on investment in securities of small and/or mid capitalization companies. The performance of large capitalization companies also tends to trail the overall market during different market cycles.

MANAGEMENT RISK. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses, including through the use of technology, automated processes, algorithms, or other management systems, that may not operate as intended or produce the desired result. There can be no guarantee that the Fund will meet its investment objective.

MARKET RISK. Market risk is the risk that a particular investment, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates and 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, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares, the liquidity of an investment, and may result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on the Fund’s shares may widen and the returns on investment may fluctuate.

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 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.

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. These errors or failures may adversely affect the Fund’s operations, including its ability to execute its investment process, calculate or disseminate its NAV or intraday indicative optimized portfolio value in a timely manner, and process creations or redemptions. The Fund relies on third-parties for a range of services, including custody, valuation, administration, transfer services, securities lending and accounting, among many others. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Fund's investment advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

discounts from, and sometimes at premiums to, their net asset value), the Fund’s investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value and the bid/ask spread on the Fund’s shares may widen.

SPECIAL TAX RISK. The Fund intends to qualify as a “regulated investment company” (“RIC”), 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, the possible application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended. 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 or long-term capital gains or losses depending on the holding period.

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.

To maintain its status as a RIC, the Fund must distribute 90% of its investment company taxable income annually. In addition, to avoid a non-deductible excise tax, the Fund must distribute 98% of its ordinary income and 98.2% of its capital gain net income. Separately, depending upon the circumstances, sales to fund redemptions could cause the Fund to recognize income that the Fund is required to distribute to maintain the Fund's RIC status and avoid the excise tax. Funding such distributions could require additional sales, which could require more distributions and affect the projected performance of the Fund. Alternatively, if the Fund only makes distributions to maintain its RIC status and becomes subject to the excise tax, that could also affect the projected performance of the Fund. In either case, the assets sold to fund redemptions, distributions or pay the excise tax will not be available to assist the Fund in meeting its target outcome. See “Federal Tax Matters” below for more information.

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.

TARGET OUTCOME PERIOD RISK. The Fund’s investment strategy is designed to deliver returns (before fees and expenses) that match the Underlying ETF if Fund shares are bought on the day on which the Fund enters into the FLEX Options (i.e., the first day of a Target Outcome Period) and held until those FLEX Options expire at the end of the Target Outcome Period subject to the cap. In the event an investor purchases Fund shares after the first day of a Target Outcome Period or sells shares prior to the expiration of the Target Outcome Period, the value of that investor’s investment in Fund shares may not be buffered against a decline in the value of the Underlying ETF and may not participate in a gain in the value of the Underlying ETF up to the cap for the investor’s investment period.

TRADING ISSUES RISK. Trading in Fund 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 Fund shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. 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. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders.

UNDERLYING ETF CONCENTRATION RISK. The Underlying ETF may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Underlying ETF's investments more than the market as a whole, to the extent that the Underlying ETF's investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.

interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market.

UNDERLYING ETF RISK. The Fund invests in FLEX Options that reference an ETF, which subjects the Fund to certain of the risks of owning shares of an ETF as well as the types of instruments in which the Underlying ETF invests. The value of an ETF will fluctuate over time based on fluctuations in the values of the securities held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, ETFs are subject to absence of an active market risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETF and, in turn, the value of the Fund’s shares. An ETF that tracks an index will not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

The Fund has characteristics unlike many other traditional investment products and may not be suitable for all investors.

The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of any state or local tax. Returns after taxes on distributions reflect the taxed return on the payment of dividends and capital gains. Returns after taxes on distributions and sale of shares assume you sold your shares at period end, and, therefore, are also adjusted for any capital gains or losses incurred. Returns for an index do not include expenses, which are deducted from Fund returns, or taxes.

Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as individual retirement accounts (IRAs) or employee-sponsored retirement plans.

Purchase and Sale of Fund Shares

The Fund issues and redeems shares on a continuous basis, at net asset value, only in large blocks of shares called “Creation Units.” Individual shares of the Fund may only be purchased and sold on the secondary market through a broker-dealer. Since shares of the Fund trade on securities exchanges in the secondary market at their market price rather than their net asset value, the Fund’s shares may trade at a price greater than (premium) or less than (discount) the Fund’s net asset value. An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”). Recent information, including the Fund’s net asset value, market price, premiums and discounts, bid-ask spreads and the median bid-ask spread for the Fund’s most recent fiscal year, is available online at http://www.ftportfolios.com/Retail/Etf/EtfSummary.aspx?Ticker=GOCT.

Tax Information

The Fund’s distributions are taxable and will generally be taxed as ordinary income or capital gains. Distributions on shares held in a tax-deferred account, while not immediately taxable, will be subject to tax when the shares are no longer held in a tax-deferred account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer, registered investment adviser, bank or other financial intermediary (collectively, “intermediaries”), First Trust and First Trust Portfolios L.P., the Fund’s distributor, may pay the intermediary for the sale of Fund 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 on the Fund's Investment Objective and Strategies

The Fund is a series of First Trust Exchange-Traded Fund VIII and is regulated as an “investment company” under the 1940 Act. The Fund is actively managed and does not seek to track the performance of an index. The Fund’s investment objective to seek to provide investors with returns (before fees and expenses) that match the price return of the Underlying ETF, up to a predetermined upside cap of 14.05% while providing a buffer (before fees and expenses) against the first 15% of Underlying ETF losses, over the period from October 19, 2026 through October 15, 2027 is non-fundamental and may be changed by the Board of Trustees of the Trust (the “Board”) without shareholder approval. Unless an investment policy is identified as being fundamental, all investment policies included in this prospectus and the Fund’s Statement of Additional Information (“SAI”) are non-fundamental and may be changed by the Board without shareholder approval. If there is a material change to the Fund's principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will achieve its investment objective. During the Fund’s initial invest-up period and during periods of high in-flows and out-flows, the Fund may not be fully invested pursuant to its principal investment strategy.

The Fund will not invest 25% or more of the value of its total assets in securities of issuers in any one industry or group of industries except to the extent that the Underlying ETF invests more than 25% of its assets in an industry or group of industries. This restriction does not apply to obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities, or securities of other investment companies.

The Fund has adopted a policy pursuant to Rule 35d-1 under the 1940 Act to invest, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in investments that provide exposure to equity securities issued by U.S. companies. Shareholders will be provided with at least 60 days' prior written notice of any change to this policy.

While it is not expected that the Fund will invest in the securities of other investment companies, any such investments would be subject to limitations imposed by the 1940 Act and the related rules and interpretations. The Fund has adopted a policy that it will not invest in other investment companies in excess of 1940 Act limits in reliance on Sections 12(d)(1)(F) or 12(d)(1)(G) of the 1940 Act.

For each Target Outcome Period, the Fund will invest in both purchased and written put and call FLEX Options that reference the Underlying ETF. The Fund generally holds in-the-money purchased call options, out-of-the-money written call options, at-the-money purchased put options and out-of-the-money written put options. The in-the-money purchased call options are intended to provide approximately one-to-one exposure to the Underlying ETF. The out-of-the-money written call options are intended to provide premiums to the Fund that will offset the cost of the in-the-money purchased call options and also limit the Fund's returns to the cap. The at-the-money purchased put options in combination with the out-of-the-money written put options are intended to provide the Fund's buffer.

FLEX Options

FLEX Options are customized equity or index option contracts that trade on an exchange, but provide investors with the ability to customize key contract terms like exercise prices, styles and expiration dates, while achieving price discovery in competitive, transparent auctions markets and avoiding the counterparty exposure of the over-the-counter option positions. FLEX Options are guaranteed for settlement by the OCC. The Fund will enter into FLEX Option contracts only with counterparties that First Trust reasonably believes are capable of performing under the contract.

The Fund will purchase and sell call and put FLEX Options based on the performance of the Underlying ETF. The FLEX Options that the Fund will hold that reference the Underlying ETF will give the Fund the right or the obligation to either receive or deliver shares of the Underlying ETF, or the right or the obligation to either receive or deliver a cash payment on the option expiration date based upon the difference between the Underlying ETF’s value and a strike price, depending on whether the option is a put or call option and whether the Fund purchases or sells the option. The FLEX Options held by the Fund are European style options, which are exercisable at the strike price only on the FLEX Option expiration date. Subject to determination by the Securities Committee of the OCC, adjustments may be made to the FLEX Options for certain events (collectively, “Corporate Actions”) specified in the OCC’s by-laws and rules: certain stock dividends or distributions, stock splits, reverse stock splits, rights offerings, distributions, reorganizations, recapitalizations, or reclassifications with respect to an underlying security, or a merger, consolidation, dissolution or liquidation of the issuer of the underlying security. According

to the OCC’s by-laws, the nature and extent of any such adjustment is to be determined by the OCC’s Securities Committee, in light of the circumstances known to it at the time such determination is made, based on its judgment as to what is appropriate for the protection of investors and the public interest, taking into account such factors as fairness to holders and writers (or purchasers and sellers) of the affected options, the maintenance of a fair and orderly market in the affected options, consistency of interpretation and practice, efficiency of exercise settlement procedures, and the coordination with other clearing agencies of the clearance and settlement of transactions in the underlying interest.

To the extent the Fund enters into derivatives transactions, it will do so pursuant to Rule 18f-4 under the 1940 Act. Rule 18f-4 requires the Fund to implement certain policies and procedures designed to manage its derivatives risks, dependent upon the Fund’s level of exposure to derivative instruments.

Non-Principal Investments

Cash Equivalents and Short-Term Investments/Temporary Defensive Positions

Normally, the Fund invests substantially all of its assets to meet its investment objective. The Fund may invest the remainder of its assets 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. For temporary defensive purposes, the Fund may depart from its principal investment strategies and invest part or all of its assets in these securities, or it may hold cash. During such periods, the Fund may not be able to achieve its investment objective. The Fund may adopt a temporary defensive strategy when the Advisor believes securities in which the Fund normally invests have elevated risks due to political or economic factors and in other extraordinary circumstances. For more information on eligible short-term investments, see the SAI.

Illiquid Investments

The Fund may invest up to 15% of its net assets in investments and other instruments that are, at the time of investment, illiquid (determined using the Securities and Exchange Commission's standard applicable to investment companies, i.e., any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment). For this purpose, illiquid investments may include, but are not limited to, restricted securities (securities the disposition of which is restricted under the federal securities laws), securities that may only be resold pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), that are deemed to be illiquid, and certain repurchase agreements.

Disclosure of Portfolio Holdings

The Fund’s portfolio holdings are available on the Fund's website at http://www.ftportfolios.com. A description of the policies and procedures with respect to the disclosure of the Fund's portfolio securities is included in the Fund's SAI, which is also available on the Fund's website.

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 disclosure pertaining to the Principal Risks set forth above as well as additional Non-Principal Risks set forth below in this prospectus. The order of the below risk factors does not indicate the significance of any particular risk factor.

Principal Risks

in a dramatic change in the spread between the Fund’s net asset value and the price at which the Fund’s shares are trading on the Exchange, which could result in a decrease in value of the Fund’s shares. This reduced effectiveness could result in Fund shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads for Fund shares.

CAPPED UPSIDE RISK. The Fund’s strategy seeks to provide returns (before fees and expenses) that match those of the Underlying ETF for Fund shares purchased on the first day of a Target Outcome Period and held for the entire Target Outcome Period, subject to a pre-determined upside cap. If an investor does not hold its Fund shares for an entire Target Outcome Period, the returns realized by that investor likely will not match those the Fund seeks to achieve. If the Underlying ETF experiences gains during a Target Outcome Period, the Fund will not participate in those gains beyond the cap. A new cap is established at the beginning of each Target Outcome Period and is dependent on prevailing market conditions. The cap may rise or fall from one Target Outcome Period to the next. In the event an investor purchases Fund shares after the first day of a Target Outcome Period and the Fund has risen in value to a level near to the cap, there may be little or no ability for that investor to experience an investment gain on their Fund shares (because the investor’s potential gain will be limited to the difference between the Fund’s NAV on the date the investor purchased the Fund shares and the cap), however, the investor will remain vulnerable to downside risks. As a result of the Fund's fees and expenses and because the Fund's returns are subject to a cap, the return of the Fund could represent a return that is worse than the performance of the Underlying ETF. If an investor buys Fund shares when the price exceeds the cap, an investor will not experience any gain regardless of the performance of the Underlying ETF. An investor that holds Fund shares through multiple Target Outcome Periods may fail to experience gains comparable to those of the Underlying ETF over time because at the end of each Target Outcome Period, a new cap will be established based on the then current price of the Underlying ETF and any gains above the prior cap will be forfeit. Moreover, the annual imposition of a new cap on future gains may make it difficult to recoup any losses from prior Target Outcome Periods such that, over multiple Target Outcome Periods, the Fund may have losses that exceed those of the Underlying ETF.

may result in wider spreads between the bid and the offered prices of the Fund’s 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.

COUNTERPARTY RISK. If the Fund enters into an investment or transaction that depends on the performance of another party, the Fund becomes subject to the credit risk of that counterparty. The Fund's ability to profit from these types of investments and transactions depends on the willingness and ability of the Fund’s counterparty to perform its obligations. If a counterparty fails to meet its contractual obligations, the Fund may be unable to terminate or realize any gain on the investment or transaction, resulting in a loss to the Fund. The Fund may experience significant delays in obtaining any recovery in an insolvency, bankruptcy, or other reorganization proceeding involving a counterparty (including recovery of any collateral posted by it) and may obtain only a limited recovery or may obtain no recovery in such circumstances. If the Fund holds collateral posted by its counterparty, it may be delayed or prevented from realizing on the collateral in the event of a bankruptcy or insolvency proceeding relating to the counterparty. Under applicable law or contractual provisions, including if the Fund enters into an investment or transaction with a financial institution and such financial institution (or an affiliate of the financial institution) experiences financial difficulties, then the Fund may in certain situations be prevented or delayed from exercising its rights to terminate the investment or transaction, or to realize on any collateral and may result in the suspension of payment and delivery obligations of the parties under such investment or transactions or in another institution being substituted for that financial institution without the consent of the Fund. Further, the Fund may be subject to “bail-in” risk under applicable law whereby, if required by the financial institution's authority, the financial institution's liabilities could be written down, eliminated or converted into equity or an alternative instrument of ownership. A bail-in of a financial institution may result in a reduction in value of some or all of securities and, if the Fund holds such securities or has entered into a transaction with such a financial security when a bail-in occurs, the Fund may also be similarly impacted.

Transactions in FLEX Options are required to be centrally cleared. In a transaction involving FLEX Options, the Fund's counterparty is the OCC, rather than a bank or broker. Since the Fund is not a member of the OCC and only members (“clearing members”) can participate directly in the OCC, the Fund will hold its FLEX Options through accounts at clearing members. Although clearing members guarantee performance of their clients’ obligations to the OCC, there is a risk that a clearing member may default. The OCC collects margin, maintains a clearing fund specifically to mitigate a clearing member default and segregates all customer accounts from a clearing member’s proprietary accounts, which further acts to protect a clearing member’s customers from the default of the clearing member. However, there is still a risk that the assets of the Fund might not be fully protected in the event of a clearing member’s default. If the Fund's clearing member defaults, the OCC may transfer customer accounts to another clearing member. The OCC may also close out positions and convert deposits of the defaulting clearing member to cash. As a result of this process, 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. Therefore, the Fund could experience significant loss in the event of a clearing member’s default. Additionally, the OCC may be unable to perform its obligations under the FLEX Options contracts due to unexpected events, which could negatively impact the value of the Fund.

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or shares of the Fund in general, may fall in value due to current market conditions.

As a means to fight inflation, the Federal Reserve and certain foreign central banks have raised interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund. While it is hard to predict whether any of these regulations will be adopted, due to the current scope of proposed regulations, any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Regulatory changes may also increase Fund operational costs, which could impact overall performance. Certain market factors may result in central banks changing their approach in the future. Potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including high interest rates, declining valuations and elevated vacancies, could have a broader impact on financial markets.

The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, such as presidential, congressional and gubernatorial elections in the U.S., global elections and governmental changes and the U.S. government’s failure to agree on a long-term budget and deficit reduction plan, have and may continue to have an adverse impact on the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The potential result of a U.S. federal government shutdown may also significantly impact investor and consumer behavior, which may adversely impact the markets and global economy. The change in

administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Global and domestic authorities and regulators have previously responded to serious economic disruptions with ranging fiscal and monetary policy changes, including but not limited to, direct capital infusions into companies, new monetary programs and dramatically lower interest rates. Any change in these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which may adversely impact the Fund’s investments and performance. Any market disruptions could also delay the Fund from making sound investment decisions in a timely manner. If the Fund concentrates its investments in a region enduring geopolitical market disruption, it may face higher risk of loss, although the increasing interconnectivity between global economies and financial markets can lead to events or conditions in one country, region or financial market adversely impacting a different country, region or financial market.

Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among the United States, Israel, Iran, Hamas, Hezbollah and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East, the United States, and other nations. Such events may also disrupt global trade and supply chains, increase sanctions and other governmental actions, and contribute to volatility in oil and natural gas markets. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others.

Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. As the use of technology grows, liquidity and market movements may be affected. As artificial intelligence is used more widely, the profitability and growth of Fund holdings may be impacted, which could significantly impact the overall performance of the Fund. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly.

These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

CYBER SECURITY RISK. The Fund is susceptible to operational, information security and related 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. These risks may not be fully covered by insurance. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber incidents include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting or destroying data, or causing operational disruption (e.g., through denial-of-service attacks to make network services unavailable to intended users). Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Emerging threats like ransomware or zero-day exploits could also cause disruptions to Fund operations. The use of cloud-based software or data storage by the Fund, the Advisor, or any of the Fund’s service providers may exacerbate these risks. Additionally, geopolitical tension may increase the scale and sophistication of deliberate attacks, particularly those from nation states or from entities with nation state backing. Unintentional events, such as power outages, natural disasters, equipment malfunctions, processing errors or market events that occur at a pace that overloads the information and technology systems relied upon by the Fund or its service providers, may also disrupt the Fund’s business operations or impact critical data. Cyber security incidents may also trigger Fund obligations under data privacy laws, potentially increasing notification and compliance burdens.

Cyber security failures by or breaches of the systems of the Advisor, distributor and other service providers (including, but not limited to, sub-advisors, index providers, fund accountants, custodians, transfer agents and administrators), market makers, authorized participants or the issuers of securities in which the Fund invests, governmental and other regulatory authorities, exchanges and other financial market operators, banks, brokers, dealers, insurance companies, other financial institutions or other parties, have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses; interference with the Fund’s ability to calculate its net asset value; disclosure of confidential trading information; impediments to trading; submission of erroneous trades or erroneous creation or redemption orders; the inability of the Fund or its service providers to transact business; violations of applicable privacy and other laws; regulatory fines penalties, reputational damage, reimbursement or other compensation costs; or additional compliance costs. Further, errors, misconduct, or compromise of accounts of employees of the Fund or its third-party service providers can also create material cybersecurity risks. Cyber incidents may render records of the Fund, including records relating to its assets and transactions, shareholder ownership of Fund shares, and other data integral to the Fund’s functioning, inaccessible, inaccurate or incomplete. Artificial intelligence (“AI”) and machine learning technologies used by the Fund, the Advisor or third-party service providers may allow the unintended introduction of vulnerabilities into infrastructures and applications, which could exacerbate these risks or result in cyber incidents that implicate personal data. The Fund and its shareholders could be negatively impacted as a result of these cyber risks associated with AI technologies. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future.

The regulatory climate governing cyber security and data protection is developing quickly and may vary considerably across jurisdictions. Regulators continue to develop new rules and standards related to cyber security and data protection. Compliance with evolving regulations can be demanding and costly, requiring substantial resources to monitor and implement required changes.

While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber incidents, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified, that such plans and systems may not completely eliminate the occurrence or mitigate the effects of cyber incidents, and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, market makers or authorized participants. However, there is no guarantee that such efforts will succeed, and the Fund and its shareholders could be negatively impacted as a result.

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 approved by the Board of Trustees of the Trust) 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. Under those circumstances, the value of the FLEX Options will require more reliance on the investment adviser’s judgment than that required for securities for which there is an active trading market. This creates a risk of mispricing or improper valuation of the FLEX Options which could impact the value paid for shares of the Fund.

INDEX OR MODEL CONSTITUENT RISK. The Fund may be a constituent of one or more indices or ETF models. As a result, the Fund may be included in one or more index-tracking ETFs or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving the Fund's shares, the size of the Fund and the market volatility of the Fund’s shares. Inclusion in an index could increase demand for the Fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result, the Fund’s net asset value could be negatively impacted and the Fund’s market price may be below the Fund's net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity. To the extent buying or selling activity increases, the Fund can be exposed to increased brokerage costs and adverse tax consequences and the market price of the Fund can be negatively affected.

INFORMATION TECHNOLOGY COMPANIES RISK. The Underlying ETF invests significantly in information technology companies. 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 product 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 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.

NON-DIVERSIFICATION RISK. The Fund is operated in a non-diversified manner. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds and may be more sensitive to any single economic, business, political or regulatory occurrence than a diversified fund. To the extent the Fund invests in a relatively small number of issuers

due to the high percentage of the Fund’s assets invested in that security, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund’s shares may be more volatile than the values of shares of more diversified funds.

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. These errors or failures may adversely affect the Fund’s operations, including its ability to execute its investment process, calculate or disseminate its NAV or intraday indicative optimized portfolio value in a timely manner, and process creations or redemptions. The Fund relies on third-parties for a range of services, including custody, valuation, administration, transfer services, securities lending and accounting, among many others. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Fund’s investment advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

The Fund, the Advisor and the Fund’s service providers may utilize AI technologies, including machine learning models and generative AI, to improve operational efficiency and in connection with research, among other purposes. The Fund and the Advisor have little control over the use of AI in third-party products or services. The use of AI introduces numerous potential challenges and the use of AI can lead to reputational damage, legal liabilities, and competitive disadvantages, as well as negatively impact business operations, which may occur with or without mismanagement in the use of the AI. AI requires the collection and processing of substantial amounts of data, which poses risks of data inaccuracies, incompleteness, and inherent biases, and which can degrade the technology’s effectiveness and reliability. Such data can include proprietary information, the use of which by AI may be unauthorized and subject to potential liability. AI also presents the risk of “misalignment.” This is the scenario where AI’s behavior becomes purposefully adversarial to the goals of the user.

OPTIONS RISK. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions and depends on the ability of the Fund's portfolio manager to forecast market movements correctly. The prices of options are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility, which in turn are affected by fiscal and monetary policies and by national and international political and economic events. As a seller (writer) of a put option, the Fund will lose money if the value of the reference index or security falls below the strike price and the buyer exercises the option; however, such loss will be partially offset by any premium received from the sale of the option. As the seller (writer) of a call option, the Fund will lose money if the value of the reference index or security rises above the strike price and the buyer exercises the option; however, such loss will be partially offset by any premium received from the sale of the option. As the buyer of a put or call option, the buyer risks losing the entire premium invested in the option if the buyer does not exercise the option. The effective use of options also depends on the Fund's ability to terminate option positions at times deemed desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. In addition, there may at times be an imperfect correlation between the movement in values of options and their underlying securities and there may at times not be a liquid secondary market for certain options. Options may also involve the use of leverage, which could result in greater price volatility than other securities.

PREMIUM/DISCOUNT RISK. The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s net asset value as well as the relative supply of and demand for shares on the Exchange. First Trust cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences 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, 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. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), First Trust believes that large discounts or premiums to the net asset value of shares should not be sustained absent disruptions to the creation and redemption mechanism, extreme market volatility or potential lack of authorized participants. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value and the bid/ask spread on the Fund’s shares may widen.

SPECIAL TAX RISK. The Fund intends to qualify as a RIC; 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, the possible

application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended. 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 or long term capital gains or losses depending on the holding period.

UNDERLYING ETF EQUITY RISK. Because the Fund holds FLEX Options that reference the Underlying ETF, the Fund has exposure to the equity securities markets. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting the issuers occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market.

and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETF and, in turn, the value of the Fund’s shares. An ETF that tracks an index will not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Non-Principal Risks

BORROWING AND LEVERAGE RISK. If the Fund borrows money, it must pay interest and other fees, which may reduce the Fund’s returns. Any such borrowings are intended to be temporary. However, under certain market conditions, including periods of decreased liquidity, such borrowings might be outstanding for longer periods of time. As prescribed by the 1940 Act, the Fund will be required to maintain specified asset coverage of at least 300% with respect to any bank borrowing immediately following such borrowing and at all times thereafter. The Fund may be required to dispose of assets on unfavorable terms if market fluctuations or other factors reduce the Fund’s asset coverage to less than the prescribed amount.

DEPENDENCE ON KEY PERSONNEL RISK. The Sub-Advisor is dependent upon the experience and expertise of the Fund's portfolio managers in providing advisory services with respect to the Fund's investments. If the Sub-Advisor were to lose the services of any of these portfolio managers, its ability to service the Fund could be adversely affected. There can be no assurance that a suitable replacement could be found for any of the portfolio managers in the event of their death, resignation, retirement or inability to act on behalf of the Sub-Advisor.

FAILURE TO QUALIFY AS A REGULATED INVESTMENT COMPANY RISK. If, in any year, the Fund fails to qualify as a regulated investment company under the applicable tax laws, the Fund would be taxed as an ordinary corporation. In such circumstances, the Fund's taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed and the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment. This would cause investors to incur higher tax liabilities than they otherwise would have incurred and would have a negative impact on Fund returns. If the Fund fails to qualify as a regulated investment company, distributions to the Fund's shareholders generally would be eligible (i) for treatment as qualified dividend income in the case of individual shareholders and (ii) for the dividends received deduction in the case of corporate shareholders. See "Federal Tax Matters."

How to Buy and Sell Shares

Most investors buy and sell shares of the Fund in secondary market transactions through brokers. Shares of the Fund are listed for trading on the secondary market on one or more national securities exchanges. Shares can be bought and sold throughout the trading day like other publicly traded shares. There is no minimum investment when buying shares on the Exchange. Although shares are generally purchased and sold in “round lots” of 100 shares, brokerage firms typically permit investors to purchase or sell shares in smaller “odd lots,” at no per-share price differential. When buying or selling shares through a broker, investors should expect to pay brokerage commissions, investors may receive less than the net asset value of the shares because shares are bought and sold at market prices rather than at net asset value, and investors may pay some or all of the bid-ask spread for each transaction (purchase or sale) of Fund shares. Share prices are reported in dollars and cents per share.

Under normal circumstances, the Fund will pay out redemption proceeds to a redeeming authorized participant within one day after the authorized participant’s redemption request is received, in accordance with the process set forth in the Fund’s SAI and in the agreement between the authorized participant and the Fund’s distributor. However, the Fund reserves the right, including under stressed market conditions, to take up to seven days after the receipt of a redemption request to pay an authorized participant, all as permitted by the 1940 Act.

For purposes of the 1940 Act, the Fund is treated as a registered investment company, and the acquisition of shares by other registered investment companies and companies relying on Sections 3(c)(1) and 3(c)(7) of the 1940 Act is subject to the restrictions of Section 12(d)(1) of the 1940 Act and the related rules and interpretations.

Book Entry

Shares are held in book-entry form, which means that no share certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund 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 share 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 price of shares of the Fund on the secondary market is based on market price and may differ from the Fund’s daily net asset value and can be affected by market forces of supply and demand, economic conditions and other factors.

Frequent Purchases and Redemptions of the Fund's Shares

The Fund imposes no restrictions on the frequency of purchases and redemptions (“market timing”). In determining not to approve a written, established policy, the Board evaluated the risks of market timing activities by the Fund's shareholders. The Board considered that the Fund's shares can only be purchased and redeemed directly from the Fund in Creation Units by broker-dealers and large institutional investors that have entered into participation agreements (i.e., authorized participants (“APs”)) and that the vast majority of trading in the Fund's shares occurs on the secondary market. Because the secondary market trades do not involve the Fund directly, it is unlikely those trades would cause many of the harmful effects of market timing, including dilution, disruption of portfolio management, increases in the Fund's trading costs and the realization of capital gains. With respect to trades directly with the Fund, to the extent effected in-kind (i.e., for securities), those trades do not cause any of the harmful effects that may result from frequent cash trades. To the extent that the Fund may effect the purchase or redemption of Creation Units in exchange wholly or partially for cash, the Board noted that such trades could result in dilution to the Fund and increased transaction costs, which could negatively impact the Fund’s ability to achieve its investment objective. However, the Board noted that direct trading by APs is critical to ensuring that the shares trade at or close to net asset value. In addition, the Fund imposes fixed and variable transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by the Fund in effecting trades. Finally, the Advisor monitors purchase and redemption orders from APs for patterns of abusive trading and the Fund reserves the right to not accept orders from APs that the Advisor has determined may be disruptive to the management of the Fund.

Dividends, Distributions and Taxes

Dividends from net investment income of the Fund, if any, are declared and paid annually by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders at least 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. Such shares will generally be reinvested by the broker based upon the market price of those shares and investors may be subject to customary brokerage commissions charged by the broker.

Federal Tax Matters

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 (“IRS”) could disagree with any conclusions set forth in this section. The following disclosure may not be sufficient for you to use for 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.

Fund Status

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

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. A “return of capital” is a return, in whole or in part, of the funds that you previously invested in the Fund. A return of capital distribution should not be considered part of a Fund’s dividend yield or total return of an investment in Fund shares. 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 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.

Dividends Received Deduction

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 RICs.

Capital Gains and Losses

If you are an individual, the maximum marginal stated federal tax rate for net capital gains 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 share 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 Internal Revenue Code of 1986, as amended, treats certain capital gains as ordinary income in special situations.

An election may be available to you to defer recognition of the gain attributable to a capital gain dividend if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements. The Fund’s positions in FLEX Options may reduce the amount of long-term capital gains, and, thus, reduce the amount of distributions eligible to be capital gain dividends.

Sale of 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 brokerage fees, if any. In some cases, however, you may have to adjust your tax basis after you purchase your shares. An election may be available to you to defer recognition of capital gain if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Taxes on Purchase and Redemption 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. See the SAI for more information. 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 the cash redemption amount. The IRS, 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 Fund Expenses

Expenses incurred and deducted by the Fund will generally not be treated as income taxable to you.

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 the 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.

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 be characterized as dividends for 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. For tax years after December 31, 2022, amounts paid to or recognized by a non-U.S. affiliate that are excluded from tax under the portfolio interest, capital gain dividends, short-term capital gains or tax-exempt interest dividend exceptions or applicable treaties, may be taken into consideration in determining whether a corporation is an “applicable corporation” subject to a 15% minimum tax on adjusted financial statement income.

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.

Distribution Plan

FTP serves as the distributor of Creation Units for the Fund on an agency basis. FTP does not maintain a secondary market in shares.

The Board has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse FTP for amounts expended to finance activities primarily intended to result in the sale of Creation Units or the provision of investor services. FTP may also use this amount to compensate securities dealers or other persons that are APs for providing distribution assistance, including broker-dealer and shareholder support and educational and promotional services.

The Fund does not currently pay 12b-1 fees, and pursuant to a contractual arrangement, the Fund will not pay 12b-1 fees any time before December 31, 2026. However, in the event 12b-1 fees are charged in the future, because these fees are paid out of the Fund's assets, over time these fees will increase the cost of your investment and may cost you more than certain other types of sales charges.

Net Asset Value

The Fund’s net asset value (“NAV”) is determined as of the close of regular trading (normally 4:00 p.m., Eastern Time) on each day the New York Stock Exchange (“NYSE”) is open for trading. If the NYSE closes early on a valuation day, the Fund’s NAV will be determined as of that time. The Fund’s NAV is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

Section 2(a)(41) of the 1940 Act provides that when a market quotation is readily available for a fund’s portfolio investment, it must be valued at the market value. Rule 2a-5 under the 1940 Act (“Rule 2a-5”) defines a readily available market quotation as “a quoted price (unadjusted) in active markets for identical investments that the fund can access at the measurement date, provided that a quotation will not be readily available if it is not reliable.” If a market quotation is not “readily available,” then the portfolio investment must be fair valued as determined in good faith by a fund’s board of trustees.

Rule 2a-5 permits a fund’s board of trustees to designate the fund’s investment adviser as its “valuation designee” to perform fair value determinations, subject to certain conditions. Accordingly, the Fund’s Board has designated First Trust as its valuation designee (the “Valuation Designee”) pursuant to Rule 2a-5 and has directed the Valuation Designee to perform the functions required in Rule 2a-5(a) subject to the requirements of Rule 2a-5(b) on behalf of all portfolio investments of the Fund, subject to the Board’s oversight. First Trust has established a pricing committee (the “Pricing Committee”) to assist in the administration of the duties of the Valuation Designee. The Valuation Designee has adopted valuation procedures for the First Trust Funds (the “Valuation Procedures”), a brief summary of which is set forth below.

The Pricing Committee has identified certain portfolio investments that are routinely categorized as having a readily available market quotation. The market value of an investment with a readily available market quotation is typically determined on the basis of official closing prices or last reported sale prices or equivalent price, although this can vary based on investment type and/or the availability of such prices.

The Pricing Committee has also identified certain portfolio investments that are routinely categorized as fair valued investments. In general, for such investments, the Fund’s accounting agent will obtain all pricing data for use in valuing such investments from a pricing service provider approved by the Pricing Committee (each, a “Pricing Service Provider”), subject to the oversight of the Pricing Committee. Pricing Service Providers typically value non-exchange-traded instruments utilizing a range of market-based inputs and assumptions. For example, when available, Pricing Service Providers may utilize inputs such as benchmark yields, reported trades, broker-dealer quotes, spreads, and transactions for comparable instruments. In pricing certain instruments, a Pricing Service Provider may consider information about an instrument’s issuer or market activity. Pricing Service Provider valuations of non-exchange-traded instruments generally represent the service’s good faith opinion as to what the holder of an instrument would receive in an orderly transaction for an institutional round lot position under current

market conditions. Certain exchange-traded options, such as FLEX Options, are typically valued using a model-based price provided by a Pricing Service Provider.

Portfolio investments trading on foreign exchanges or over-the-counter markets that close prior to the close of the NYSE may be fair valued using a systematic fair valuation model provided by a Pricing Service Provider. If these foreign securities meet certain criteria in relation to the valuation model, their valuation is systematically adjusted to reflect the impact of movement in the U.S. market after the close of certain foreign markets.

If no price is available from a Pricing Service Provider or if the Pricing Committee has reason to question the accuracy or the reliability of a price supplied for a portfolio investment or the use of amortized cost, the Pricing Committee will determine the fair value of such portfolio investment in a manner that it believes most appropriately reflects the fair value of the portfolio investment on the valuation date (a “Special Fair Value Pricing Situation”). In a Special Fair Value Pricing Situation, the Pricing Committee will determine a fair value price subject to the process outlined in the Valuation Procedures and based on a consideration of all available information to the Pricing Committee at the time of the determination.

Additionally, for foreign securities, if an extraordinary market event occurs between the time the last “current” market quotation is available for a security in the Fund’s portfolio and the time the Fund’s NAV is determined that calls into doubt whether that earlier market quotation represents fair value at the time the Fund’s NAV is determined, the Pricing Committee will determine the fair valuation as set forth in the Valuation Procedures.

Fair value represents a good faith approximation of the value of a portfolio investment and is the amount the Fund might reasonably expect to receive from the current sale of that investment in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations, if any, and that may not be the prices at which those investments could have been sold during the period in which the particular fair values were used. While the Valuation Procedures and Valuation Designee’s processes are intended to result in the Fund’s NAV calculation that fairly reflects the values as of the time of pricing, the fair value determined for a portfolio instrument may be materially different from the value that could be realized upon the sale of that instrument.

Foreign currencies are translated into U.S. dollars at the exchange rate of such currencies against the U.S. dollar as provided by a Pricing Service Provider. All assets denominated in foreign currencies will be converted into U.S. dollars at the exchange rates in effect at the time of valuation.

Other Information

Continuous Offering

The Fund issues, on a continuous offering basis, its shares in one or more groups of a fixed number of Fund shares (each such group of such specified number of individual Fund shares, a “Creation Unit Aggregation”). The method by which Creation Unit Aggregations of Fund shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Unit Aggregations of shares are issued and sold by the Fund on an ongoing basis, a “distribution,” as such term is used in the Securities Act of 1933, as amended (the "Securities Act"), may occur at any point. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the Securities Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Unit Aggregations after placing an order with FTP, breaks them down into constituent shares and sells such shares directly to customers, or if it chooses to couple the creation of a supply of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a characterization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. As a result, broker-dealer firms should note that dealers who are not underwriters but are participating in a distribution (as contrasted with ordinary secondary market transactions) and thus dealing with the shares that are part of an overallotment within the meaning of Section 4(a)(3)(C) of the Securities Act would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the Securities Act. Firms that incur a prospectus delivery obligation with respect to shares are reminded that, under the Securities Act Rule 153, a prospectus delivery obligation under Section 5(b)(2) of the Securities Act owed to a broker-dealer in connection with a sale on the Exchange is satisfied by the fact that the prospectus is available from the Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is available with respect to transactions on a national securities exchange, a trading facility or an alternative trading system.

FTP, or its affiliates, or a fund or unit investment trust for which FTP or an affiliate serves as sponsor or investment advisor, may purchase shares of the Fund through a broker-dealer or other investors, including in secondary market transactions, and because FTP or its affiliates may be deemed affiliates of the Fund, the shares are being registered to permit the resale of these shares from time to time after any such purchase. The Fund will not receive any of the proceeds from the resale of such shares.
