Summary Information

First Trust Indxx Critical Metals ETF (FMTL)

Investment Objective

The First Trust Indxx Critical Metals ETF (the “Fund”) seeks investment results that correspond generally to the price and yield (before the Fund’s fees and expenses) of an index called the Indxx Global Critical Metals Index (the “Index”).

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.

Shareholder Fees
(fees paid directly from your investment)

Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)

None

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

Management Fees	0.65%
Distribution and Service (12b-1) Fees	0.00%
Other Expenses(1)	0.00%
Total Annual Fund Operating Expenses	0.65%

(1)

“Other Expenses” is an estimate based on the expenses the Fund expects to incur for the current fiscal year.

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
$66	$208

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. The Fund has no operational history and therefore no historical turnover rate.

Principal Investment Strategies

The Fund will normally invest at least 80% of its net assets (including investment borrowings) in the securities that comprise the Index. The Fund, using an indexing investment approach, attempts to replicate, before fees and expenses, the performance of the Index. The Index is owned and is developed, maintained and sponsored by Indxx, Inc. (the “Index Provider”).

wind power plants: gallium, platinum, dysprosium, neodymium, praseodymium, terbium and copper. The “NextGen Mobility Metals” sub-theme classifies those companies that are engaged in the mining and provision of the following Critical Metals that are used in the production of batteries for electric vehicles: lithium, nickel, cobalt and aluminum. The “Other High Technology Metals” sub-theme classifies those companies that are engaged in the mining and provision of the following Critical Metals used in rapidly growing advanced technology industries which are not covered by the other two sub-themes, such as smart phones, digital cameras, computer hard disks, fluorescent and light-emitting diode (LED) lights, flat screen televisions, computer monitors and electronic displays: graphite, magnesium, iridium, silicon, uranium and fluorine.

According to the Index Provider, for a company’s security to be eligible for inclusion in the Index, it must: (i) be listed in the United States or in a developed market or emerging market (excluding Vietnam), as determined by the Index Provider; (ii) be listed in a country that is either a member of or a partner to the Minerals Security Partnership, an initiative led by the U.S. Department of State that brings together partner nations to secure and diversify critical mineral supply chains; (iii) earn revenue from the United States or North America; (iv) be engaged in the mining and provision of a Critical Metal; (v) have no mining or processing in China or Russia; and (vi) meet the size, liquidity, price, security type and seasoning requirements of the Index. If a company issues more than one security that meets the eligibility requirements of the Index, the Index Provider determines which security may be eligible for inclusion in the Index based on current constituency, type of security and liquidity.

According to the Index Provider, the Index Provider then selects from the remaining eligible securities those which are earning positive revenue from the United States or North America in the last fiscal year.

According to the Index Provider, the Index Provider then classifies the remaining eligible securities into a Sustainable Energy Metals, NextGen Mobility Metals or Other High Technology Metals sub-theme. According to the Index Provider, the foregoing sub-themes, including the metals identified thereunder, are subject to change based upon new research and developments in the field at the time of every reconstitution.

According to the Index Provider, the Index Provider will then select from the remaining eligible securities the top fifty (50) companies by market capitalization to be included in the Index. If fewer than fifty (50) companies qualify for inclusion, then all of the remaining eligible constituents will be included in the Index.

According to the Index Provider, Index securities are weighted based on their security-level free float market capitalization. No individual security for any company that derives less than 25% of its revenue from Critical Metals may be weighted above 4.5%. No security for any company that derives more than 25% of its revenue from Critical Metals may be weighted above 8%. Any individual security with excess weight shall be redistributed proportionately among the remaining securities in the Index. The aggregate weight of securities with weight greater than or equal to 5.0% shall not exceed 45% of the Index. If the aggregate weight of securities exceeds 45% of the portfolio, a secondary cap of 4.5% will be applied with any excess weight being redistributed proportionately among the remaining securities in the Index.

At each reconstitution, the Index will allocate 80% of its weight to securities that derive a majority of their revenue from mining metals and minerals, including Critical Metals. This also includes revenue derived from metal and mineral derivatives that have either direct or indirect applications in one or more of the sub-themes defined above.

The Index is reconstituted and rebalanced semi-annually and the Fund will make corresponding changes to its portfolio shortly after the Index changes are made public. The Index’s semi-annual rebalance schedule may cause the Fund to experience a higher rate of portfolio turnover. The Fund will be concentrated in an industry or a group of industries to the extent that the Index is so concentrated. As of October 31, 2025, the Index had significant investments in materials companies, although this may change from time to time. The Fund’s investments will change as the Index changes and, as a result, the Index may have significant investments in jurisdictions or investment sectors that it may not have had as of October 31, 2025. To the extent the Fund invests a significant portion of its assets in a given jurisdiction or investment sector, the Fund may be exposed to the risks associated with that jurisdiction or investment sector.

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

Principal Risks

You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund’s investment objective will be achieved. The order of the below risk factors does not indicate the significance of any particular risk factor.

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount (the difference between the market price of the Fund's shares and the Fund's net asset value) and possibly face delisting and the bid/ask spread (the difference between the price that someone is willing to pay for shares of the Fund at a specific point in time versus the price at which someone is willing to sell) on the Fund’s shares may widen.

CRITICAL METALS MINING COMPANIES RISK. Companies engaged in the mining of Critical Metals face a unique set of risks that can significantly impact their operations and financial performance. The profitability and valuations of Critical Metals mining companies are highly sensitive to the prices of the underlying Critical Metals they produce. Prices for these commodities can be volatile and are influenced by supply-demand dynamics, speculation, macroeconomic trends, changes in technology (such as battery chemistries), and actions by governments or large producers. A decline in the market price of one or more Critical Metals may significantly reduce the earnings, cash flows, and market valuations of such mining companies and the Fund’s performance. The mining industry is inherently cyclical and sensitive to fluctuations in global economic activity. Economic expansions or contractions in sectors that drive demand for Critical Metals such as artificial intelligence, electric vehicles, renewable energy and electronics can significantly impact revenue and profitability. Overinvestment during commodity booms often leads to supply gluts and sharp price declines during bust cycles. Rapid technological innovation may negatively impact the long-term demand for Critical Metals. Companies that fail to adapt to changes in technologies may be negatively affected. Mining projects, particularly those in the exploration or development phase, carry high technical and economic uncertainty. The feasibility of a project depends on factors such as ore quality, extraction costs, infrastructure availability, financing and commodity price assumptions. Companies may expend great amounts of resources on a project only to have it never reach commercial production or only reach commercial production at unfavorable economics. Mining companies are subject to operational risks including mine accidents, equipment failures, labor disputes, cybersecurity breaches, natural disasters and unexpected geological conditions. Many mines are located in remote areas with limited infrastructure, which can exacerbate logistical and cost challenges. Any sustained disruption of operations may lead to production shortfalls and financial underperformance. Mining companies involved in Critical Metals may face intense scrutiny due to the environmental degradation associated with mining processes, including habitat destruction, water contamination, and hazardous waste production. Licenses to operate may be revoked or impaired if companies are perceived as failing to meet community, labor or environmental standards. Increasing global ESG mandates may restrict institutional capital flows to certain mining operations or compel costly changes to production practices. Companies failing to adhere to ESG norms may face reputational harm, reduced access to capital or regulatory sanctions. Governments may assert increased control over their natural resources through higher taxes, royalties, export quotas, nationalization of mining assets or preferential treatment of domestic companies. These forms of resource nationalism can significantly impair the profitability of foreign-listed mining firms. Additionally, global supply chains for Critical Metals are increasingly viewed as strategic and may be disrupted by geopolitical tensions, trade wars or national security concerns. Political instability, armed conflict, corruption, and weak rule of law in certain countries may pose significant threats to mining operations. In particular, assets may be seized, contracts voided, or operations disrupted due to regime changes, civil unrest or shifts in political leadership. Sanctions, tariffs and other forms of economic retaliation may further restrict investment or operations in certain countries. Mining operations are subject to a complex framework of local, national and international environmental and safety regulations, including requirements for obtaining and renewing exploration and extraction permits. Regulatory frameworks are subject to change and may become more stringent, increasing compliance costs or causing delays or denials of key operating permits. Projects can be delayed for years or halted indefinitely due to environmental opposition, litigation, or local community resistance. Such risks may impair production timelines and the financial viability of the underlying companies in the Fund.

CURRENCY RISK. Changes in currency exchange rates affect the value of investments denominated in a foreign currency, and therefore the value of such investments in the Fund’s portfolio. The Fund’s net asset value could decline if a currency to which the Fund has exposure depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning.

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; however, the Federal Reserve has begun to lower 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 Israel, Iran, Hamas 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 and the United States. 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.

DEPOSITARY RECEIPTS RISK. Depositary receipts represent equity interests in a foreign company that trade on a local stock exchange. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

EMERGING MARKETS RISK. Investments in securities issued by companies operating in emerging market countries involve additional risks relating to political, economic, or regulatory conditions not associated with investments in securities and instruments issued by U.S. companies or by companies operating in other developed market countries. Investments in emerging markets securities are generally considered speculative in nature and are subject to the following heightened risks: smaller market capitalization of securities markets which may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; possible repatriation of investment income and capital; rapid inflation; and currency convertibility issues. Emerging market countries also often have less uniformity in accounting, auditing and reporting requirements, unsettled securities laws, unreliable securities valuation and greater risk associated with custody of securities. Financial and other reporting by companies also may be less reliable in emerging market countries. Shareholder claims that are available in the U.S., as well as regulatory oversight and authority that is common in the U.S., including for claims based on fraud, may be difficult or impossible for shareholders of securities in emerging market countries or for U.S. authorities to pursue. The Index the Fund seeks to track does not weight the securities in emerging market countries on the basis of investor protection limitations, financial reporting quality or available oversight mechanisms. Furthermore, investors may be required to register with the government of an emerging market country the proceeds of sales of securities and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies.

EQUITY SECURITIES RISK. The value of the Fund's shares will fluctuate with changes in the value of the equity securities in which it invests. 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 an issuer 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.

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.

INDEX PROVIDER RISK. There is no assurance that the Index Provider, or any agents that act on its behalf, will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. The Index Provider and its agents do not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and do not guarantee that the Index will be calculated in accordance with its stated methodology. The Advisor’s mandate as described in this prospectus is to manage the Fund consistently with the Index provided by the Index Provider. The Advisor relies upon the Index provider and its agents to accurately compile, maintain, construct, reconstitute, rebalance, compose, calculate and disseminate the Index accurately. Therefore, losses or costs associated with any Index Provider or agent errors generally will be borne by the Fund and its shareholders. To correct any such error, the Index Provider or its agents may carry out an unscheduled rebalance of the Index or other modification of Index constituents or weightings. When the Fund in turn rebalances its portfolio, any transaction costs and market exposure arising from such portfolio rebalancing will be borne by the Fund and its shareholders. Unscheduled rebalances also expose the Fund to additional tracking error risk. Errors in respect of the quality, accuracy and completeness of the data used to compile the Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the Index is less commonly used as a benchmark by funds or advisors. For example, during a period where the Index contains incorrect constituents, the Fund tracking the Index would have market exposure to such constituents and would be underexposed to the Index’s other constituents. Such errors may negatively impact the Fund and its shareholders. The Index Provider and its agents rely on various sources of information to assess the criteria

of issuers included in the Index, including information that may be based on assumptions and estimates. Neither the Fund nor the Advisor can offer assurances that the Index’s calculation methodology or sources of information will provide an accurate assessment of included issuers. Unusual market conditions or issuer-specific events may cause the Index Provider to postpone a scheduled rebalance, exclude or substitute a security in the Index or undertake other measures which could cause the Index to vary from its normal or expected composition. The postponement of a scheduled rebalance in a time of market volatility could mean that constituents that would otherwise be removed at rebalance due to changes in market capitalizations, issuer credit ratings, or other reasons may remain, causing the performance and constituents of the Index to vary from those expected under normal conditions. Apart from scheduled rebalances, the Index Provider or its agents may carry out additional ad hoc rebalances to the Index due to unusual market conditions or in order, for example, to correct an error in the selection of index constituents.

INTERNATIONAL CLOSED MARKET TRADING RISK. Because securities held by the Fund trade on non-U.S. exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market) used for purposes of calculating the Fund's net asset value, resulting in premiums or discounts to the Fund’s net asset value that may be greater than those experienced by other exchange-traded funds. In addition, shareholders may not be able to purchase and sell shares of the Fund on the listing exchange for the Fund, on days when the net asset value of the Fund could be significantly affected by events in the relevant foreign markets.

LARGE CAPITALIZATION COMPANIES RISK. 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.

LIQUIDITY RISK. The Fund may hold certain investments that may be subject to restrictions on resale, trade over-the-counter or in limited volume, or lack an active trading market. Certain investments held by the Fund that trade on non-U.S. exchanges may be further subject to liquidity risk due to foreign market closures or unexpected impediments to trading in local markets. Accordingly, the Fund may not be able to sell or close out of such investments at favorable times or prices (or at all), or at the prices approximating those at which the Fund currently values them. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value and the bid/ask spread on the Fund's shares may widen.

MARKET MAKER 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 markers. 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. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s 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 discount to net asset value and also in greater than normal intraday bid-ask spreads for Fund shares.

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.

MATERIALS COMPANIES RISK. Materials and processing companies are involved in the extraction or processing of raw materials such as metals, ore and forestry products. These companies are sensitive to changes in the business cycle and fluctuations in the supply and demand for raw materials. Further, certain materials and processing companies can be affected

by shifts in the housing market, as many produced raw materials are components of construction projects. Rising wage costs can also impact companies that rely on skilled labor. In addition, materials and processing companies may be significantly affected by volatility of commodity prices, import controls, worldwide competition, liability for environmental damage, depletion of resources and mandated expenditures for safety and pollution control devices.

MID CAPITALIZATION COMPANIES RISK. Mid capitalization companies may be more vulnerable to adverse general market or economic developments and thus may experience greater price volatility than more established large capitalization companies. Securities of mid capitalization companies may also be less liquid than securities of large capitalization companies and may have more limited trading volumes. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

NEW FUND RISK. The Fund is new and has no performance history or assets as of the date of this prospectus. The Fund expects to have fewer assets than larger funds. Like other new funds, large inflows and outflows may impact the Fund’s market exposure, and in turn, the Fund’s returns for limited periods of time.

NON-CORRELATION RISK. The Fund’s return may not match the return of the Index for a number of reasons. The Fund incurs operating expenses not applicable to the Index, and may incur costs in buying and selling securities, especially when rebalancing the Fund’s portfolio holdings to reflect changes in the composition of the Index. In addition, the Fund’s portfolio holdings may not exactly replicate the securities included in the Index or the ratios between the securities included in the Index. Additionally, in order to comply with its investment strategies and policies, the Fund portfolio may deviate from the composition of the Index. Accordingly, the Fund's return may underperform the return of the Index.

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.

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

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.

PASSIVE INVESTMENT RISK. The Fund is not actively managed. The Fund invests in securities included in or representative of the Index regardless of investment merit. The Fund generally will not attempt to take defensive positions in declining markets. In the event that the Index is no longer calculated, the Index license is terminated or the identity or character of the Index is materially changed, the Fund will seek to engage a replacement index.

PORTFOLIO TURNOVER RISK. High portfolio turnover may result in the Fund paying higher levels of transaction costs and may generate greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than expected.

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), 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.

SMALL CAPITALIZATION COMPANIES RISK. Small capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than large and mid capitalization companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than large and mid capitalization companies.

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.

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. Fund investments that trade on non-U.S. exchanges that close prior to the close of the Exchange may be fair valued using a systematic fair valuation model. If these foreign investments 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. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Performance

The Fund does not have a performance history. Once available, the Fund’s performance information, and information that gives some indication of the risks of an investment in the Fund by comparing the Fund’s performance with a broad measure of market performance, will be available on the Fund’s website at http://www.ftportfolios.com. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

The Investment Committee members are primarily and jointly responsible for the day-to-day management of the Fund. Each Investment Committee member has served as a part of the portfolio management team of the Fund since October 2025.

Purchase and Sale of Fund Shares

The Fund intends to issue and redeem 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/home.aspx.

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 II and is regulated as an “investment company” under the 1940 Act. The Fund operates as an index fund and is not actively managed by First Trust. As such, the Fund’s investment objective is to seek investment results that correspond generally to the price and yield (before the Fund’s fees and expenses) of the Index. In seeking to achieve this objective, the Fund will normally invest at least 80% of its net assets (including investment borrowings) in the securities that comprise the Index. Indxx, Inc. serves as the index provider for the index tracked by the Fund and may be referred to throughout this prospectus as the “Index Provider.” While the Index Provider may consult with First Trust, the Fund’s investment advisor, prior to effectuating a material change to the Index methodology, First Trust maintains no discretion with regard to the compilation and composition of the Index or any changes thereto as such discretion ultimately lies with the Index Provider. The Index Provider is not affiliated with the Fund, the Fund's investment advisor or the Fund's distributor.

The Fund will generally employ a full replication strategy, meaning that it will normally invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, full replication of the Index may not be possible or practicable. In those circumstances, the Fund may purchase a sample of securities in the Index. The Fund may utilize sampling when there are practical difficulties or substantial costs involved in replicating the Index, including to address tax and regulatory issues and respond to trading halts and other issues related to the liquidity of Index constituents. There may also be instances in which First Trust may choose to overweight certain securities in the Index, purchase securities not in the Index which First Trust believes are appropriate to substitute for certain securities in the Index, use futures or derivative instruments or utilize various combinations of the above techniques in seeking to track the Index. The Fund may sell securities that are represented in the Index in anticipation of their removal from the Index or purchase securities not represented in the Index in anticipation of their addition to the Index. 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’s investment objective, its 80% investment strategy and each of the policies described herein are non-fundamental policies that may be changed by the Board of Trustees of the Trust (the “Board”) without shareholder approval upon 60 days’ prior written notice to shareholders. Certain fundamental policies of the Fund are set forth in the Statement of Additional Information (“SAI”) under “Investment Objective and Policies.”

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.

The Fund has adopted a non-fundamental investment policy pursuant to Rule 35d-1 under the 1940 Act (the “Name Policy”), whereby the Fund, under normal market conditions, will invest at least 80% of its net assets (including investment borrowings) in the securities comprising the Index. The Name Policy may be changed by the Board without shareholder approval upon 60 days’ prior written notice.

Indxx Global Critical Metals Index

According to the Index Provider, the Index is a market capitalization weighted index designed to track the performance of companies that are engaged in the mining of metals or minerals that have a high risk of supply disruption (each such metal or mineral a “Critical Metal” or, collectively, “Critical Metals”). According to the Index Provider, the Index is composed of companies that earn revenue in the United States or North America through the mining of Critical Metals (or the derivatives thereof) that have either direct or indirect applications in one of the following sub-themes: (i) Sustainable Energy Metals; (ii) NextGen Mobility Metals; or (iii) Other High Technology Metals. The “Sustainable Energy Metals” sub-theme classifies those companies that are engaged in the mining and provisions of the following Critical Metals used in the production of solar and wind power plants: gallium, platinum, dysprosium, neodymium, praseodymium, terbium and copper. The “NextGen Mobility Metals” sub-theme classifies those companies that are engaged in the mining and provision of the following Critical Metals that are used in the production of batteries for electric vehicles: lithium, nickel, cobalt and aluminum. The “Other High Technology Metals” sub-theme classifies those companies that are engaged in the mining and provision of the following Critical Metals used in rapidly growing advanced technology industries which are not covered by the other two sub-themes, such as smart phones, digital cameras, computer hard disks, fluorescent and light-emitting diode (LED) lights, flat screen televisions, computer monitors and electronic displays: graphite, magnesium, iridium, silicon, uranium and fluorine.

listed in a country that is either a member of or a partner to the Minerals Security Partnership, an initiative led by the U.S. Department of State that brings together partner nations to secure and diversify critical mineral supply chains; (iii) earn revenue from the United States or North America; (iv) be engaged in the mining and provision of a Critical Metal; (v) have no mining or processing in China or Russia; and (vi) meet the size, liquidity, price, security type and seasoning requirements of the Index. If a company issues more than one security that meets the eligibility requirements of the Index, the Index Provider determines which security may be eligible for inclusion in the Index based on current constituency, type of security and liquidity.

The Index is reconstituted and rebalanced semi-annually and the Fund will make corresponding changes to its portfolio shortly after the Index changes are made public.

The Fund will be concentrated in an industry or a group of industries to the extent that the Index is so concentrated.

The Fund is classified as “non-diversified” under the 1940 Act.

Fund Investments

Principal Investments

Equity Securities

The Fund invests in common stocks and depositary receipts. Common stock represents an equity ownership interest in issuers. Holders of common stock are entitled to the income and increase in the value of the assets and business of the issuers after all debt obligations and obligations to preferred stockholders are satisfied. Depositary receipts are certificates typically issued by a bank or trust company that represent ownership interests in securities of non-U.S. companies. Depositary receipts may or may not be jointly sponsored by the underlying issuer.

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 objectives. 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 objectives. The Fund may adopt

a temporary defensive strategy when the portfolio managers believe 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 supplemental 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

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. However, participants are not obligated to make a market in the Fund’s shares or submit purchase and redemption orders for creation units. To the extent that these institutions exit the business, reduce their role or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting and the bid/ask spread on the Fund’s shares may widen.

or environmental standards. Increasing global ESG mandates may restrict institutional capital flows to certain mining operations or compel costly changes to production practices. Companies failing to adhere to ESG norms may face reputational harm, reduced access to capital or regulatory sanctions. Governments may assert increased control over their natural resources through higher taxes, royalties, export quotas, nationalization of mining assets or preferential treatment of domestic companies. These forms of resource nationalism can significantly impair the profitability of foreign-listed mining firms. Additionally, global supply chains for Critical Metals are increasingly viewed as strategic and may be disrupted by geopolitical tensions, trade wars or national security concerns. Political instability, armed conflict, corruption, and weak rule of law in certain countries may pose significant threats to mining operations. In particular, assets may be seized, contracts voided, or operations disrupted due to regime changes, civil unrest or shifts in political leadership. Sanctions, tariffs and other forms of economic retaliation may further restrict investment or operations in certain countries. Mining operations are subject to a complex framework of local, national and international environmental and safety regulations, including requirements for obtaining and renewing exploration and extraction permits. Regulatory frameworks are subject to change and may become more stringent, increasing compliance costs or causing delays or denials of key operating permits. Projects can be delayed for years or halted indefinitely due to environmental opposition, litigation, or local community resistance. Such risks may impair production timelines and the financial viability of the underlying companies in the Fund.

CURRENCY RISK. Changes in currency exchange rates affect the value of investments denominated in a foreign currency, the value of dividends and interest earned from such securities and gains and losses realized on the sale of such securities. The Fund’s net asset value could decline if a currency to which the Fund has exposure depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. Changes in currency exchange rates may affect the Fund's net asset value, the value of dividends and interest earned, and gains and losses realized on the sale of securities. An increase in the strength of the U.S. dollar relative to other currencies may cause the value of the Fund to decline. Certain non-U.S. currencies may be particularly volatile, and non-U.S. governments may intervene in the currency markets, causing a decline in value or liquidity in the Fund's non-U.S. holdings whose value is tied to the affected non-U.S. currency. Additionally, the prices of non-U.S. securities that are traded in U.S. dollars are often indirectly influenced by currency fluctuations.

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; however, the Federal Reserve has begun to lower 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 Israel, Iran, Hamas 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 and the United States. 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.

DEPOSITARY RECEIPTS RISK. Depositary receipts are securities issued by a bank or trust company reflecting ownership of underlying securities issued by a foreign company. An investment in depositary receipts involves further risks due to certain unique features. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights pursuant to a deposit agreement between the underlying issuer and the depositary. In certain cases, the depositary will vote the shares deposited with it as directed by the underlying issuer’s board of directors. Furthermore, investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert shares into depositary receipts and vice versa. Such restrictions may cause shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipt. Moreover, if depositary receipts are converted into shares, the laws in certain countries may limit the ability of a non-resident to trade the shares and to reconvert the shares to depositary receipts. Depositary receipts may be “sponsored” or “unsponsored.” Sponsored depositary receipts are established jointly by a depositary and the underlying issuer, whereas unsponsored depositary receipts may be established by a depositary without participation by the underlying issuer. Holders of unsponsored depositary receipts generally bear all the costs associated with establishing the unsponsored depositary receipts. In addition, the issuers of the securities underlying unsponsored depositary receipts are not obligated to disclose material information in the U.S. and, therefore, there may be less information available regarding such issuers and there may not be a correlation between such information and the market value of the depositary receipts.

EMERGING MARKETS RISK. Investments in securities issued by governments and companies operating in emerging market countries involve additional risks relating to political, economic, or regulatory conditions not associated with investments in securities and instruments issued by U.S. companies or by companies operating in other developed market countries. This is due to, among other things, the potential for greater market volatility, lower trading volume, a lack of liquidity, potential for market manipulation, higher levels of inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments in emerging market countries than are typically found in more developed market countries. Also, certain regions, countries or asset types may suffer periods of relative illiquidity. Moreover, emerging market countries often have less uniformity in accounting and reporting requirements, unsettled securities laws, less reliable securities valuations and greater risks associated with custody of securities than developed markets. In addition, the Public Company Accounting Oversight Board, which regulates auditors of U.S. public companies, may be unable to inspect audit work papers in certain emerging market countries. Emerging market countries often have greater risk of capital controls through such measures as taxes or interest rate control than developed markets. Certain emerging market countries may also lack the infrastructure necessary to attract large amounts of foreign trade and investment. Local securities markets in emerging market countries may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible. Settlement procedures in emerging market countries are frequently less developed and reliable than those in the U.S. and other developed market countries. In addition, significant delays may occur in registering the transfer of securities. Settlement or registration problems may make it more difficult for the Fund to value its portfolio securities and could cause the Fund to miss attractive investment opportunities. Investing in emerging market countries involves a higher risk of expropriation, nationalization, confiscation of assets and property or the

imposition of restrictions on foreign investments and on repatriation of capital invested by certain emerging market countries. Enforcing legal rights may be made difficult, costly and slow in emerging markets as there may be additional problems enforcing claims against non-U.S. governments. As such, the rights and remedies associated with emerging market investment securities may be different than those available for investments in more developed markets. For example, it may be more difficult for shareholders to bring derivative litigation or for U.S. regulators to bring enforcement actions against issuers in emerging markets.

In addition, due to the differences in regulatory, accounting, audit and financial recordkeeping standards, including financial disclosures, less information about emerging market companies is publicly available and information that is available may be unreliable or outdated. This may affect the Index Provider’s ability to compute and construct the Index and may further impede the Advisor’s ability to accurately evaluate the index data provided. This potential for error in index construction and index data could affect the overall performance of the Fund.

EQUITY SECURITIES RISK. The value of the Fund’s shares will fluctuate with changes in the value of the equity securities in which it invests. 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. Additionally, holders of an issuer's common stock may be subject to greater risks than holders of its preferred stock and debt securities because common stockholders' claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of an issuer.

INDEX CONCENTRATION RISK. The Fund will be concentrated in an industry or a group of industries to the extent that the Index is so concentrated. To the extent that the Fund invests a significant percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is more broadly diversified. There may be instances in which the Index, for a variety of reasons including changes in the prices of individual securities held by the Fund, has a larger exposure to a small number of stocks or a single stock relative to the rest of the stocks in the Index. Under such circumstances, the Fund will not deviate from the Index except in rare circumstances or in an immaterial way and therefore the Fund’s returns would be more greatly influenced by the returns of the stock(s) with the larger exposure.

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.

exposure to such constituents and would be underexposed to the Index’s other constituents. Such errors may negatively impact the Fund and its shareholders. The Index Provider and its agents rely on various sources of information to assess the criteria of issuers included in the Index, including information that may be based on assumptions and estimates. Neither the Fund nor the Advisor can offer assurances that the Index’s calculation methodology or sources of information will provide an accurate assessment of included issuers. Unusual market conditions or issuer-specific events may cause the Index Provider to postpone a scheduled rebalance, exclude or substitute a security from the Index or undertake other measures which could cause the Index to vary from its normal or expected composition. The postponement of a scheduled rebalance in a time of market volatility could mean that constituents that would otherwise be removed at rebalance due to changes in market capitalizations, issuer credit ratings, or other reasons may remain, causing the performance and constituents of the Index to vary from those expected under normal conditions. Apart from scheduled rebalances, the Index Provider or its agents may carry out additional ad hoc rebalances to the Index due to unusual market conditions or in order, for example, to correct an error in the selection of index constituents.

INTERNATIONAL CLOSED MARKET TRADING RISK. Because securities held by the Fund trade on non-U.S. exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market) used for purposes of calculating the Fund's net asset value, resulting in premiums or discounts to the Fund’s net asset value that may be greater than those experienced by other exchange-traded funds. In addition, shareholders may not be able to purchase and sell shares of the Fund on days when the net asset value of the Fund could be significantly affected by events in the relevant foreign markets.

LARGE CAPITALIZATION COMPANIES RISK. The Fund may invest 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.

LIQUIDITY RISK. The Fund may hold certain investments that it may not be able to dispose of or close out readily at a favorable time or price (or at all), or at a price approximating the Fund's’s valuation of the investment. For example, certain investments may be subject to restrictions on resale, may trade over-the-counter or in limited volume, or may not have an active trading market. Certain investments held by the Fund that trade on non-U.S. exchanges may be further subject to liquidity risk due to foreign market closures or unexpected impediments to trading in local markets. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value and the bid/ask spread on the Fund's shares may widen. It may be difficult for the Fund's to value illiquid securities accurately. The market for certain investments may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. If the Fund's needed to sell a large block of illiquid securities to meet shareholder redemption request or to raise cash, these sales could further reduce the securities’ prices and adversely affect performance of the Fund. Disposal of illiquid securities may entail registration expenses and other transaction costs that are higher than those for liquid securities.

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.

MATERIALS COMPANIES RISK. The Fund invests significantly in materials companies. Materials and processing companies are involved in the extraction or processing of raw materials such as metals, ore and forestry products. Changes in world events, political and economic conditions, energy conservation, environmental policies, commodity price volatility, changes in currency exchange rates, imposition of import controls, increased competition, depletion of resources, technical progress and labor relations, among other factors, may adversely affect materials and processing companies. These companies are also at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

NON-CORRELATION RISK. The Fund’s return may not match the return of its Index for a number of reasons. The Fund incurs operating expenses not applicable to its Index and may incur costs in buying and selling securities, especially when rebalancing the Fund’s portfolio holdings to reflect changes in the composition of the Index. In addition, the Fund’s portfolio holdings may not exactly replicate the securities included in its Index or the ratios between the securities included in the Index. Additionally, in order to comply with its investment strategies and policies, the Fund portfolio may deviate from the composition of the Index. Accordingly, the Fund's return may underperform the return of the Index.

NON-DIVERSIFICATION RISK. 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.

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

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.

PASSIVE INVESTMENT RISK. The Fund is not actively managed. The Fund invests in securities included in or representative of its Index regardless of investment merit. The Fund generally will not attempt to take defensive positions in declining markets. In the event that the Index is no longer calculated, the Index license is terminated or the identity or character of the Index is materially changed, the Fund will seek to engage a replacement index.

PORTFOLIO TURNOVER RISK. The Fund has an investment strategy that may frequently involve buying and selling portfolio securities. High portfolio turnover may result in the Fund paying higher levels of transaction costs, including brokerage commissions, dealer mark-ups and other costs and may generate greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than expected.

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.

at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

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.

CASH TRANSACTIONS RISK. The Fund may, under certain circumstances, effect a portion of creations and redemptions for cash, rather than in-kind securities. As a result, an investment in the Fund may be less tax-efficient than an investment in an ETF that effects its creations and redemptions only 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.

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."

INTELLECTUAL PROPERTY RISK. The Fund relies on a license between First Trust and the Index Provider that permits the Fund to use its Index and associated trade names, trademarks and service marks (the “Intellectual Property”) in connection with the Fund’s name and investment strategies. Such license may be terminated by the Index Provider, and, as a result, the Fund may lose its ability to use the Intellectual Property. There is also no guarantee that the Index Provider has all rights to license the Intellectual Property for use by the Fund. Accordingly, in the event the license is terminated or the Index Provider does not have rights to license the Intellectual Property, it may have a significant effect on the operation of the Fund.

ISSUER SPECIFIC CHANGES RISK. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

LEGISLATION/LITIGATION RISK. From time to time, various legislative initiatives are proposed and/or enacted in the United States and abroad, which may have a negative impact on certain companies in which the Fund invests. In addition, litigation regarding any of the issuers of the securities owned by the Fund, or industries represented by these issuers, may negatively impact the value of the securities. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Advisor determines to sell such a holding.

Management Fee

Pursuant to an investment management agreement between First Trust and the Trust, on behalf of the Fund (the “Investment Management Agreement”), First Trust manages the investment of the Fund's assets. First Trust is paid an annual unitary management fee by the Fund equal to 0.65% of the Fund's average daily net assets and is responsible for the Fund's expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses, if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, expenses associated with short sales transactions, if any, distribution and service fees payable pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses.

As approved by the Trust’s Board of Trustees, the management fee paid to First Trust will be reduced at certain levels of Fund net assets (“breakpoints”). See the Fund's Statement of Additional Information for more information on the breakpoints.

A discussion regarding the Board’s approval of the Investment Management Agreement will be available in the Fund’s Form N-CSR for the fiscal period ended March 31, 2026.

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. If the Fund has foreign investments in a country where a local market holiday, or series of consecutive holidays, or the extended delivery cycles for transferring foreign investments to redeeming authorized participants prevents the Fund from delivering such foreign investments to an authorized participant in response to a redemption request, the Fund may take up to 15 days after the receipt of the redemption request to deliver such investments to the authorized participant.

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, if any, are declared and paid semi-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 qualify as a “regulated investment company” (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, as further discussed below, 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. However, certain ordinary income dividends on shares that are attributable to qualifying dividends received by the Fund from certain corporations may be reported by the Fund as being eligible for the dividends received deduction.

Capital Gains and Losses and Certain Ordinary Income Dividends

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

Net capital gain equals net long-term capital gain minus net short-term capital loss for the taxable year. Capital gain or loss is long-term if the holding period for the asset is more than one year and is short-term if the holding period for the asset is one year or less. You must exclude the date you purchase your shares to determine your holding period. However, if you receive a capital gain dividend from the Fund and sell your shares at a loss after holding them 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.

Ordinary income dividends received by an individual shareholder from a RIC such as the Fund are generally taxed at the same rates that apply to net capital gain (as discussed above), provided certain holding period requirements are satisfied and provided the dividends are attributable to qualifying dividends received by the Fund itself. The Fund will provide notice to its shareholders of the amount of any distribution which may be taken into account as a dividend which is eligible for the capital gains tax rates.

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. 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.

Non-U.S. Tax Credit

If the Fund invests in non-U.S. securities, the tax statement that you receive may include an item showing non-U.S. taxes the Fund paid to other countries. In this case, dividends taxed to you will include your share of the taxes the Fund paid to other countries. You may be able to deduct or receive a tax credit for your share of these taxes.

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 may be subject to a U.S. withholding tax of 30% in the case of distributions to (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. This withholding tax is also currently scheduled to apply to the gross proceeds from the disposition of securities that produce U.S. source interest or dividends. However, proposed regulations may eliminate the requirement to withhold on payments of gross proceeds from dispositions.

It is the responsibility of the entity through which you hold your shares to determine the applicable withholding.

Investments in Certain Non-U.S. Corporations

If the Fund holds an equity interest in any “passive foreign investment companies” (“PFICs”), which are generally certain non-U.S. corporations that receive at least 75% of their annual gross income from passive sources (such as interest, dividends, certain rents and royalties or capital gains) or that hold at least 50% of their assets in investments producing such passive income, the Fund could be subject to U.S. federal income tax and additional interest charges on gains and certain distributions with respect to those equity interests, even if all the income or gain is timely distributed to its shareholders. The Fund will not be able to pass through to its shareholders any credit or deduction for such taxes. The Fund may be able to make an election that could ameliorate these adverse tax consequences. In this case, the Fund would recognize as ordinary income any increase in the value of such PFIC shares, and as ordinary loss any decrease in such value to the extent it did not exceed prior increases included in income. Under this election, the Fund might be required to recognize in a year income in excess of its distributions from PFICs and its proceeds from dispositions of PFIC stock during that year, and such income would nevertheless be subject to the distribution requirement and would be taken into account for purposes of the 4% excise tax. Dividends paid by PFICs are not treated as qualified dividend income.

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 October 31, 2027. 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, 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.
