FRANKLIN DISRUPTIVE COMMERCE ETF

Performance Summary as of September 30, 2023

Total return reflects reinvestment of the Fund’s dividends and capital gain distributions, if any, and any unrealized gains or losses. Total returns do not include brokerage commissions that may be payable on secondary market transactions. The performance table does not reflect any taxes that a shareholder would pay on Fund dividends, capital gain distributions, if any, or any realized gains on the sale or redemption of Fund shares.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (Market Price) is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary trading (2/27/20), the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV.

Your dividend income will vary depending on dividends or interest paid by securities in the Fund’s portfolio, adjusted for operating expenses. Capital gain distributions are net profits realized from the sale of portfolio securities.

Performance as of 9/30/23¹

PERFORMANCE SUMMARY

Total Annual Operating Expenses⁵

Events such as the spread of deadly diseases, disasters, and financial, political or social disruptions, may heighten risks and adversely affect performance. The Fund is actively managed but there is no guarantee that the manager’s investment decisions will produce the desired results.

All investments involve risks, including possible loss of principal. Equity securities are subject to price fluctuation and possible loss of principal. 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. By focusing its investments in consumer discretionary-related industries, the Fund carries much greater risks of adverse developments and price movements in such industries than a fund that invests in a wider variety of industries. International investments are subject to special risks, including currency fluctuations and social, economic and political uncertainties, which could increase volatility. These risks are magnified in emerging markets. The portfolio is non-diversified and may invest in a relatively small number of issuers, which may negatively impact the Fund’s performance and result in greater fluctuation in the value of the Fund’s shares. The manager may consider environmental, social and governance (ESG) criteria in the research or investment process; however, ESG considerations may not be a determinative factor in security selection. In addition, the manager may not assess every investment for ESG criteria, and not every ESG factor may be identified or evaluated. These and other risks are discussed in the Fund’s prospectus.

ETFs trade like stocks, fluctuate in market value and may trade at prices above or below their net asset value. Brokerage commissions and ETF expenses will reduce returns.

1. The total annual operating expenses are as of the Fund’s prospectus available at the time of publication. Actual expenses may be higher and may impact portfolio returns.

2. Total return calculations represent the cumulative and average annual changes in value of an investment over the periods indicated. Return for less than one year, if any, has not been annualized.

3. Assumes reinvestment of distributions based on net asset value.

Your Fund’s Expenses

As a Fund shareholder, you can incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of Fund shares; and (2) ongoing Fund costs, including management fees and other Fund expenses. All funds have ongoing costs, sometimes referred to as operating expenses. The table below shows ongoing costs of investing in the Fund and can help you understand these costs and compare them with those of other funds. The table assumes a $1,000 investment held for the six months indicated.

Actual Fund Expenses

The table below provides information about actual account values and actual expenses in the columns under the heading “Actual.” In these columns the Fund’s actual return, which includes the effect of Fund expenses, is used to calculate the “Ending Account Value.” You can estimate the expenses you paid during the period by following these steps (of course, your account value and expenses will differ from those in this illustration): Divide your account value by $1,000 (if your account had an $8,600 value, then $8,600 ÷ $1,000 = 8.6). Then multiply the result by the number in the row under the headings “Actual” and “Expenses Paid During Period” (if Actual Expenses Paid During Period were $7.50, then 8.6 × $7.50 = $64.50). In this illustration, the actual expenses paid this period are $64.50.

Hypothetical Example for Comparison with Other Funds

Under the heading “Hypothetical” in the table, information is provided about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. This information may not be used to estimate the actual ending account balance or expenses you paid for the period, but it can help you compare ongoing costs of investing in the Fund with those of other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that expenses shown in the table are meant to highlight ongoing costs and do not reflect any transactional costs. Therefore, information under the heading “Hypothetical” is useful in comparing ongoing costs only, and will not help you compare total costs of owning different funds. In addition, if transactional costs were included, your total costs would have been higher.

1. Expenses are equal to the annualized expense ratio for the six-month period as indicated above—in the far right column—multiplied by the simple average account value over the period indicated, and then multiplied by 183/366 to reflect the one-half year period.

Events such as the spread of deadly diseases, disasters, and financial, political or social disruptions, may heighten risks and adversely affect performance. The Fund is actively managed but there is no guarantee that the manager’s investment decisions will produce the desired results.

All investments involve risks, including possible loss of principal. Fixed income securities involve interest rate, credit, inflation and reinvestment risks, and possible loss of principal. As interest rates rise, the value of fixed income securities falls. Low-rated, high-yield bonds are subject to greater price volatility, illiquidity and possibility of default. Changes in the credit rating of a bond, or in the credit rating or financial strength of a bond’s issuer, insurer or guarantor, may affect the bond’s value. Unrated debt securities have less public information and independent credit analysis and they may be subject to a greater risk of illiquidity, price changes or default. These and other risks are discussed in the Fund’s prospectus.

ETFs trade like stocks, fluctuate in market value and may trade at prices above or below their net asset value. Brokerage commissions and ETF expenses will reduce returns.

1. The total annual operating expenses are sourced from the Fund’s prospectus available at the time of publication. Actual expenses may be higher and may impact portfolio returns.

2. Effective December 1, 2022, the Fund adopted a unified fee structure whereby Management has agreed to reimburse the Fund’s acquired fund fees and expenses (if any) and pay all of the ordinary operating expenses of the Fund, excluding: (i) payments under the Fund’s Rule 12b-1 plan (if any); (ii) brokerage expenses (including any costs incidental to transactions in portfolio securities or instruments); (iii) taxes; (iv) interest (including borrowing costs and dividend expenses on securities sold short and overdraft charges); (v) litigation expenses (including litigation to which the Trust or a Fund may be a party and indemnification of the Trustees and officers with respect thereto); and (vi) other non-routine or extraordinary expenses.

3. Total return calculations represent the cumulative and average annual changes in value of an investment over the periods indicated. Return for less than one year, if any, has not been annualized.

4. Assumes reinvestment of distributions based on net asset value.

5. Assumes reinvestment of distributions based on market price.

6. Distribution rate is based on an annualization of the September dividend and the NAV per share on 9/30/23.

7. The Fund’s 30-day standardized yield is calculated over a trailing 30-day period using the yield to maturity on bonds and/or the dividends accrued on stocks. It may not equal the Fund’s actual income distribution rate, which reflects the Fund’s past dividends paid to shareholders.

8. Taxable equivalent yield assumes the 2023 maximum federal income tax rate of 37.00% plus 3.80% Medicare tax.

Total return reflects reinvestment of the Fund’s dividends and capital gain distributions, if any, and any unrealized gains or losses. Total returns do not include brokerage commissions that may be payable on secondary market transactions. The performance tables do not reflect any taxes that a shareholder would pay on Fund dividends, capital gain distributions, if any, or any realized gains on the sale or redemption of Fund shares.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (Market Price) is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary trading (6/1/18), the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV.

Your dividend income will vary depending on dividends or interest paid by securities in the Fund’s portfolio, adjusted for operating expenses. Capital gain distributions are net profits realized from the sale of portfolio securities.

Events such as the spread of deadly diseases, disasters, and financial, political or social disruptions, may heighten risks and adversely affect performance. The Fund is actively managed but there is no guarantee that the manager’s investment decisions will produce the desired results.

All investments involve risks, including possible loss of principal. Fixed income securities involve interest rate, credit, inflation and reinvestment risks, and possible loss of principal. As interest rates rise, the value of fixed income securities falls. Distributions are not guaranteed and are subject to change. Low-rated, high-yield bonds are subject to greater price volatility, illiquidity and possibility of default. Changes in the credit rating of a bond, or in the credit rating or financial strength of a bond’s issuer, insurer or guarantor, may affect the bond’s value.

Your Fund’s Expenses

As a Fund shareholder, you can incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of Fund shares; and (2) ongoing Fund costs, including management fees and other Fund expenses. All funds have ongoing costs, sometimes referred to as operating expenses. The table below shows ongoing costs of investing in the Fund and can help you understand these costs and compare them with those of other funds. The table assumes a $1,000 investment held for the six months indicated.

Actual Fund Expenses

The table below provides information about actual account values and actual expenses in the columns under the heading “Actual.” In these columns the Fund’s actual return, which includes the effect of Fund expenses, is used to calculate the “Ending Account Value.” You can estimate the expenses you paid during the period by following these steps (of course, your account value and expenses will differ from those in this illustration): Divide your account value by $1,000 (if your account had an $8,600 value, then $8,600 ÷ $1,000 = 8.6). Then multiply the result by the number in the row under the headings “Actual” and “Expenses Paid During Period” (if Actual Expenses Paid During Period were $7.50, then 8.6 × $7.50 = $64.50). In this illustration, the actual expenses paid this period are $64.50.

Hypothetical Example for Comparison with Other Funds

Under the heading “Hypothetical” in the table, information is provided about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. This information may not be used to estimate the actual ending account balance or expenses you paid for the period, but it can help you compare ongoing costs of investing in the Fund with those of other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that expenses shown in the table are meant to highlight ongoing costs and do not reflect any transactional costs. Therefore, information under the heading “Hypothetical” is useful in comparing ongoing costs only, and will not help you compare total costs of owning different funds. In addition, if transactional costs were included, your total costs would have been higher.

1. Expenses are equal to the annualized expense ratio for the six-month period as indicated above—in the far right column—multiplied by the simple average account value over the period indicated, and then multiplied by 183/366 to reflect the one-half year period.

Performance Summary as of September 30, 2023

Total return reflects reinvestment of the Fund’s dividends and capital gain distributions, if any, and any unrealized gains or losses. Total returns do not include brokerage commissions that may be payable on secondary market transactions. The performance tables do not reflect any taxes that a shareholder would pay on Fund dividends, capital gain distributions, if any, or any realized gains on the sale or redemption of Fund shares.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (Market Price) is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary trading (6/8/23), the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV.

Your dividend income will vary depending on dividends or interest paid by securities in the Fund’s portfolio, adjusted for operating expenses. Capital gain distributions are net profits realized from the sale of portfolio securities.

Events such as the spread of deadly diseases, disasters, and financial, political or social disruptions, may heighten risks and adversely affect performance. The Fund is actively managed but there is no guarantee that the manager’s investment decisions will produce the desired results.

All investments involve risks, including possible loss of principal. The Fund is newly organized, with a limited history of operations. Bond prices generally move in the opposite direction of interest rates. Thus, as the prices of bonds in the Fund adjust to a rise in interest rates, the Fund’s share price may decline. Changes in the financial strength of a bond issuer or in a bond’s credit rating may affect its value. Low-rated, high-yield bonds are subject to greater price volatility, illiquidity and possibility of default. Stock prices fluctuate, sometimes rapidly and dramatically, due to factors affecting individual companies, particular industries or sectors, or general market conditions. Investments in equity index-linked notes often have risks similar to their underlying securities, which could include management risk, market risk and, as applicable, foreign securities and currency risks. The allocation of assets among different strategies, asset classes and investments may not prove beneficial or produce the desired results. Derivative instruments can be illiquid, may disproportionately increase losses, and have a potentially large impact on performance. The manager may consider environmental, social and governance (ESG) criteria in the research or investment process; however, ESG considerations may not be a determinative factor in security selection. In addition, the manager may not assess every investment for ESG criteria, and not every ESG factor may be identified or evaluated.

Events such as the spread of deadly diseases, disasters, and financial, political or social disruptions, may heighten risks and adversely affect performance. The Fund is actively managed but there is no guarantee that the manager’s investment decisions will produce the desired results.

All investments involve risks, including possible loss of principal. Equity securities are subject to price fluctuation and possible loss of principal. 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. By focusing its investments in technology-related industries, the Fund carries much greater risks of adverse developments and price movements in such industries than a fund that invests in a wider variety of industries. The portfolio is non-diversified and may invest in a relatively small number of issuers, which may negatively impact the Fund’s performance and result in greater fluctuation in the value of the Fund’s shares. International investments are subject to special risks, including currency fluctuations and social, economic and political uncertainties, which could increase volatility. These risks are magnified in emerging markets. The manager may consider environmental, social and governance (ESG) criteria in the research or investment process; however, ESG considerations may not be a determinative factor in security selection. In addition, the manager may not assess every investment for ESG criteria, and not every ESG factor may be identified or evaluated. These and other risks are discussed in the Fund’s prospectus.

Under the heading “Hypothetical” in the table, information is provided about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. This information may not be used to estimate the actual ending account balance or expenses you paid for the period, but it can help you compare ongoing costs of investing in the Fund with those of other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that expenses shown in the table are meant to highlight ongoing costs and do not reflect any transactional costs. Therefore, information under the heading “Hypothetical” is useful in comparing ongoing costs only, and will not help you compare total costs of owning different funds. In addition, if transactional costs were included, your total costs would have been higher.

1. Expenses are equal to the annualized expense ratio for the six-month period as indicated above—in the far right column—multiplied by the simple average account value over the period indicated, and then multiplied by 183/366 to reflect the one-half year period.

1. Dividends are generally subject to state and local taxes, if any. For investors subject to alternative minimum tax, a small portion of Fund dividends may be taxable. Distributions of capital gains are generally taxable. To avoid imposition of 28% backup withholding on all Fund distributions and redemption proceeds, U.S. investors must be properly certified on Form W-9 and non-U.S. investors on Form W-8BEN

2. Source: Morningstar. Treasuries, if held to maturity, offer a fixed rate of return and a fixed principal value; their interest payments and principal are guaranteed.

The index is unmanaged and includes reinvestment of any income or distributions. It does not reflect any fees, expenses or sales charges. One cannot invest directly in an index, and an index is not representative of the Fund’s portfolio.

Performance Summary as of September 30, 2023

Total return reflects reinvestment of the Fund’s dividends and capital gain distributions, if any, and any unrealized gains or losses. Total returns do not include brokerage commissions that may be payable on secondary market transactions. The performance tables do not reflect any taxes that a shareholder would pay on Fund dividends, capital gain distributions, if any, or any realized gains on the sale or redemption of Fund shares.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (Market Price) is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary trading (9/5/17), the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV.

Your dividend income will vary depending on dividends or interest paid by securities in the Fund’s portfolio, adjusted for operating expenses. Capital gain distributions are net profits realized from the sale of portfolio securities.

Events such as the spread of deadly diseases, disasters, and financial, political or social disruptions, may heighten risks and adversely affect performance. The Fund is actively managed but there is no guarantee that the manager’s investment decisions will produce the desired results.

All investments involve risks, including possible loss of principal. Fixed income securities involve interest rate, credit, inflation and reinvestment risks, and possible loss of principal. As interest rates rise, the value of fixed income securities falls. Changes in the credit rating of a bond, or in the credit rating or financial strength of a bond’s issuer, insurer or guarantor, may affect the bond’s value. Low-rated, high-yield bonds are subject to greater price volatility, illiquidity and possibility of default. Green bonds may not result in direct environmental benefits, and the issuer may not use proceeds as intended or to appropriate new or additional projects. The manager may consider environmental, social and governance (ESG) criteria in the research or investment process; however, ESG considerations may not be a determinative factor in security selection. In addition, the manager may not assess every investment for ESG criteria, and not every ESG factor may be identified or evaluated. These and other risks are discussed in the Fund’s prospectus.

ETFs trade like stocks, fluctuate in market value and may trade at prices above or below their net asset value. Brokerage commissions and ETF expenses will reduce returns.

1. The total annual operating expenses are sourced from the Fund’s prospectus available at the time of publication. Actual expenses may be higher and may impact portfolio returns.

2. Effective December 1, 2022, the Fund adopted a unified fee structure whereby Management has agreed to reimburse the Fund’s acquired fund fees and expenses (if any) and pay all of the ordinary operating expenses of the Fund, excluding: (i) payments under the Fund’s Rule 12b-1 plan (if any); (ii) brokerage expenses (including any costs incidental to transactions in portfolio securities or instruments); (iii) taxes; (iv) interest (including borrowing costs and dividend expenses on securities sold short and overdraft charges); (v) litigation expenses (including litigation to which the Trust or a Fund may be a party and indemnification of the Trustees and officers with respect thereto); and (vi) other non-routine or extraordinary expenses.

3. Total return calculations represent the cumulative and average annual changes in value of an investment over the periods indicated. Return for less than one year, if any, has not been annualized.

4. Assumes reinvestment of distributions based on net asset value.

5. Assumes reinvestment of distributions based on market price.

6. Distribution rate is based on an annualization of the September dividend and the NAV per share on 9/30/23.

7. The Fund’s 30-day standardized yield is calculated over a trailing 30-day period using the yield to maturity on bonds and/or the dividends accrued on stocks. It may not equal the Fund’s actual income distribution rate, which reflects the Fund’s past dividends paid to shareholders.

8. Taxable equivalent yield assumes the 2023 maximum federal income tax rate of 37.00% plus 3.80% Medicare tax.

9. Figures are as stated in the Fund’s current prospectus and may differ from the expense ratios disclosed in the Your Fund’s Expenses and Financial Highlights sections in this report.

Your Fund’s Expenses

As a Fund shareholder, you can incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of Fund shares; and (2) ongoing Fund costs, including management fees and other Fund expenses. All funds have ongoing costs, sometimes referred to as operating expenses. The table below shows ongoing costs of investing in the Fund and can help you understand these costs and compare them with those of other funds. The table assumes a $1,000 investment held for the six months indicated.

Actual Fund Expenses

The table below provides information about actual account values and actual expenses in the columns under the heading “Actual.” In these columns the Fund’s actual return, which includes the effect of Fund expenses, is used to calculate the “Ending Account Value.” You can estimate the expenses you paid during the period by following these steps (of course, your account value and expenses will differ from those in this illustration): Divide your account value by $1,000 (if your account had an $8,600 value, then $8,600 ÷ $1,000 = 8.6). Then multiply the result by the number in the row under the headings “Actual” and “Expenses Paid During Period” (if Actual Expenses Paid During Period were $7.50, then 8.6 × $7.50 = $64.50). In this illustration, the actual expenses paid this period are $64.50.

Hypothetical Example for Comparison with Other Funds

Under the heading “Hypothetical” in the table, information is provided about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. This information may not be used to estimate the actual ending account balance or expenses you paid for the period, but it can help you compare ongoing costs of investing in the Fund with those of other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that expenses shown in the table are meant to highlight ongoing costs and do not reflect any transactional costs. Therefore, information under the heading “Hypothetical” is useful in comparing ongoing costs only, and will not help you compare total costs of owning different funds. In addition, if transactional costs were included, your total costs would have been higher.
