SUMMARY PROSPECTUS

Investment Goal

Capital appreciation.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. You may also incur other fees, such as usual and customary brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and the Example that follows.

Annual Fund Operating Expenses

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

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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

SUMMARY PROSPECTUS

in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 19.82% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets in equity securities of companies that are relevant to the Fund’s investment theme of intelligent machines. The Fund invests predominantly in common stock.

Companies relevant to the Fund’s investment theme of intelligent machines are those that the investment manager believes are substantially focused on and/or are expected to substantially benefit from the ongoing technology-driven transformation of products, software, systems and machinery as well as product design, manufacture, logistics, distribution and maintenance, including through developments in artificial intelligence. These companies may include those that develop, produce, manufacture, design, maintain and deliver products or services with new capabilities previously unavailable in the marketplace.

The Fund's investment theme of intelligent machines is intended to capture companies that the investment manager believes represent the next phase of technological evolution, including companies that provide new systems, logistics solutions, methods, processes, products or services based on physical applications of new technologies and technological innovation. Such companies include those the investment manager believes are well-positioned to benefit from intelligent design (e.g., simulation software and computer-aided design or "CAD" software), intelligent production (e.g., advancements in manufacturing or factory automation capabilities), intelligent products (e.g., robotic-assisted technologies, tools and services) and intelligent predictive maintenance (e.g., industrial software solutions and services).

In pursuing the Fund’s investment theme, the investment manager may invest in companies in any economic sector or of any market capitalization and may invest in companies both inside and outside of the United States, including those in developing or emerging markets. Although the Fund may invest across economic sectors, it expects to have significant positions in particular sectors including technology. The Fund is a “non-diversified” fund, which means it generally invests a greater proportion of its assets in the securities of one or more issuers and invests overall in a smaller number of issuers than a diversified fund.

In selecting companies that the investment manager believes are relevant to the Fund’s investment theme of intelligent machines, the investment manager seeks to identify, using its own fundamental, “bottom-up” research and analysis, companies

FRANKLIN INTELLIGENT MACHINES ETF
SUMMARY PROSPECTUS

positioned to capitalize on disruptive innovation in or that are enabling the further development of the intelligent machines theme in the markets in which they operate. The investment manager’s internal research and analysis leverages insights from diverse sources, including external research, to develop and refine its investment theme and identify and take advantage of trends that have ramifications for individual companies or entire industries. The investment manager also evaluates market segments, products, services and business models positioned to benefit significantly from disruptive innovations in intelligent products, design, manufacturing and/or predictive maintenance relative to broad securities markets, and seeks to identify the primary beneficiaries of new trends or developments in physical applications of these innovations to select investments for the Fund.

The investment manager may seek to sell a security if: (i) the security reaches its valuation target; (ii) the security reaches its position size limit in the Fund’s portfolio; (iii) the security’s fundamentals deteriorate; (iv) there are adverse policy changes that could affect the security’s outlook; or (v) better investment opportunities become available.

Principal Risks

You could lose money by investing in the Fund. ETF shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value (NAV), trading price, yield, total return and ability to meet its investment goal. Unlike many ETFs, the Fund is not an index-based ETF.

Thematic Investing The Fund’s investment strategies incorporate the identification of thematic investment opportunities and its performance may be negatively impacted if the investment manager does not correctly identify such opportunities or if the theme develops in an unexpected manner. Performance may also be negatively impacted if the securities selected for the Fund’s portfolios do not benefit from the development of the Fund’s investment theme. Securities selected pursuant to the Fund’s investment theme may be impacted by factors unrelated to the theme, particularly with respect to companies that may have multiple lines of business, and may underperform. Adverse developments and risks unrelated to the Fund’s investment theme affecting companies in which the Fund invests may negatively impact the Fund’s performance.

The Fund’s thematic investments will also subject the Fund to growth style investing risks. Growth stock prices reflect projections of future earnings or revenues, and can, therefore, fall dramatically if the company fails to meet those projections. Growth stocks may be more expensive relative to their current earnings

FRANKLIN INTELLIGENT MACHINES ETF
SUMMARY PROSPECTUS

or assets compared to value or other stocks, and if earnings growth expectations moderate, their valuations may return to more typical norms, causing their stock prices to fall. Prices of these companies’ securities may be more volatile than other securities, particularly over the short term.

Market The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

The global outbreak of the novel strain of coronavirus, COVID-19 and its subsequent variants, has resulted in market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. The long-term impact on economies, markets, industries and individual issuers is not known. Some sectors of the economy and individual issuers have experienced or may experience particularly large losses. Periods of extreme volatility in the financial markets; reduced liquidity of many instruments; and disruptions to supply chains, consumer demand and employee availability, may continue for some time.

Stock prices tend to go up and down more dramatically than those of debt securities. A slower-growth or recessionary economic environment could have an adverse effect on the prices of the various stocks held by the Fund.

Focus To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investment from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.

Technology companies. Companies operating within the technology sector may be affected by worldwide technological developments, the success of their products and services (which may be outdated quickly), anticipated products or services that are delayed or cancelled, and investor perception of the company and/or its products or services. These companies typically face intense competition and potentially rapid product obsolescence. They may also have limited product lines, markets, financial resources or personnel. Technology companies are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. There can be no assurance these companies will be able to successfully protect their intellectual property to prevent the misappropriation of their technology, or that competitors will not develop technology that is substantially similar or superior to such companies’ technology. These companies typically engage in significant amounts of spending on research and

FRANKLIN INTELLIGENT MACHINES ETF
SUMMARY PROSPECTUS

development, and there is no guarantee that the products or services produced by these companies will be successful. Technology companies are also potential targets for cyberattacks, which can have a materially adverse impact on the performance of these companies. In addition, companies operating within the technology sector may develop and/or utilize artificial intelligence. Artificial intelligence technology could face increasing regulatory scrutiny in the future, which may limit the development of this technology and impede the growth of companies that develop and/or utilize this technology. Similarly, the collection of data from consumers and other sources could face increased scrutiny as regulators consider how the data is collected, stored, safeguarded and used. The customers and/or suppliers of technology companies may be concentrated in a particular country, region or industry. Any adverse event affecting one of these countries, regions or industries could have a negative impact on these companies.

Small and Mid-Capitalization Companies  Securities issued by small and mid-capitalization companies may be more volatile in price than those of larger companies, involve substantial risks and should be considered speculative. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, and lack of depth of management and funds for growth and development. They may also have limited product lines or be developing or marketing new products or services for which markets are not yet established and may never become established. In addition, small and mid-capitalization companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans.

Foreign Securities (non-U.S.) Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: (i) internal and external political and economic developments – e.g., the political, economic and social policies and structures of some foreign countries may be less stable and more volatile than those in the U.S. or some foreign countries may be subject to trading restrictions or economic sanctions; (ii) trading practices – e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; (iii) availability of information – e.g., foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; (iv) limited markets – e.g., the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and (v) currency exchange rate fluctuations and policies – e.g., fluctuations may negatively affect investments denominated in foreign currencies and any income received or expenses paid by the Fund in that foreign currency. The risks of foreign investments may be greater in developing or emerging market countries.

FRANKLIN INTELLIGENT MACHINES ETF
SUMMARY PROSPECTUS

Developing Market Countries The Fund’s investments in securities of issuers in developing market countries are subject to all of the risks of foreign investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation or currency devaluation.

Non-Diversification Because the Fund is non-diversified, it may be more sensitive to economic, business, political or other changes affecting individual issuers or investments than a diversified fund, which may negatively impact the Fund's performance and result in greater fluctuation in the value of the Fund’s shares.

Management The Fund is subject to management risk because it is an actively managed ETF. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.

Cybersecurity Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to fund assets, fund or customer data (including private shareholder information), or proprietary information, cause the fund, the investment manager, authorized participants, or index providers (as applicable) and listing exchanges, and/or their service providers (including, but not limited to, fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent fund investors from purchasing, redeeming shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the fund or the investment manager. Cybersecurity incidents may result in financial losses to the fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents occurring from time to time.

FRANKLIN INTELLIGENT MACHINES ETF
SUMMARY PROSPECTUS

Market Trading The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. Any of these factors, among others, may lead to the Fund’s shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than NAV when you buy shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those shares in the secondary market. The investment manager cannot predict whether shares will trade above (premium), below (discount) or at NAV.

To the extent that the underlying securities held by the Fund trade on an exchange that is closed when the securities exchange on which the Fund shares list and trade is open, there may be market uncertainty about the stale security pricing (i.e., the last quote from its closed foreign market) resulting in premiums or discounts to NAV that may be greater than those experienced by other ETFs.

Authorized Participant Concentration Only an authorized participant (Authorized Participant) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that act as Authorized Participants. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units (as defined below), Fund shares may trade at a discount to NAV and possibly face trading halts and/or delisting. This risk may be more pronounced in volatile markets, potentially where there are significant redemptions in ETFs generally.

Small Fund When the Fund's size is small, the Fund may experience low trading volume and wide bid-ask spreads. In addition, the Fund may face the risk of being delisted if the Fund does not meet certain conditions of the listing exchange.

Large Shareholder Certain shareholders, including other funds or accounts advised by the investment manager or an affiliate of the investment manager, may from time to time own a substantial amount of the Fund’s shares. In addition, a third-party investor, the investment manager or an affiliate of the investment manager, an authorized participant, a lead market maker, or another entity may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large

FRANKLIN INTELLIGENT MACHINES ETF
SUMMARY PROSPECTUS

percentage of the trading volume on the listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

Performance

Purchase and Sale of Fund Shares

The Fund is an ETF. Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund issues or redeems shares that have been aggregated into blocks of 50,000 shares or multiples thereof (Creation Units) to Authorized Participants who have entered into agreements with the Fund’s distributor, Franklin Distributors, LLC. The Fund will generally issue or redeem Creation Units in exchange for a basket of securities (and an amount of cash) that the Fund specifies each day.

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

FRANKLIN INTELLIGENT MACHINES ETF
SUMMARY PROSPECTUS

information on the Fund’s NAV, market price, premiums and discounts, and bid-ask spreads is available on the Fund’s website at https://www.franklintempleton.com/investor/investments-and-solutions/investment-options/etfs/.

Taxes

The Fund’s distributions are generally taxable to you as ordinary income, capital gains, or some combination of both, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account, in which case your distributions would generally be taxed when withdrawn from the tax-advantaged account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the investment manager or other related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. 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.
