^ There is no guarantee the issuers of the securities included in the trust will declare dividends or distributions in the future. The historical 12-month distribution per unit and historical 12-month distribution rate of the securities included in the trust are for illustrative purposes only and are not indicative of the trust's distribution or distribution rate. The historical 12-month distribution per unit is based on the weighted average of the trailing twelve month distributions paid by the securities included in the portfolio. The historical 12-month distribution rate is calculated by dividing the historical 12-month distributions by the trust's offering price. The historical 12-month distribution and rate are reduced to account for the effects of fees and expenses, which will be incurred when investing in a trust. Certain of the issuers may have reduced their dividends or distributions over the prior twelve months. The distribution per unit and rate paid by the trust may be higher or lower than the amount shown above due to certain factors that may include, but are not limited to, a change in the dividends or distributions paid by issuers, actual expenses incurred, or the sale of securities in the portfolio. For trusts that include funds, distributions may include realized short term capital gains, realized long-term capital gains and/or return of capital.

Risk Considerations

Closed-End Fund Risk. Closed-end funds are subject to various risks, including management's ability to meet the fund's investment objective, and to manage the fund's portfolio when the underlying securities are redeemed or sold, during periods of market turmoil and as investors' perceptions regarding the funds or their underlying investments change. Unlike open-end funds, which trade at prices based on a current determination of the fund's net asset value, closed-end funds frequently trade at a discount to their net asset value in the secondary market. Certain closed-end funds employ the use of leverage, which increases the volatility of such funds.

COVID-19 Economic Impact Risk. The COVID-19 global pandemic has caused significant volatility and declines in global financial markets, causing losses for investors. The development of vaccines has slowed the spread of the virus and allowed for the resumption of "reasonably" normal business activity in the United States, although many countries continue to impose lockdown measures. Additionally, there is no guarantee that vaccines will be effective against emerging variants of the disease.

Floating Rate Risk. Certain of the funds invest in floating-rate securities. A floating-rate security is an instrument in which the interest rate payable on the obligation fluctuates on a periodic basis based upon changes in an interest rate benchmark. As a result, the yield on such a security will generally decline in a falling interest rate environment, causing the trust to experience a reduction in the income it receives from such securities.   

Investment Grade Bonds Risk. Investment grade securities are subject to numerous risks including higher interest rates, economic recession, deterioration of the investment grade security market or investors' perception thereof, possible downgrades and defaults of interest and/or principal.

Municipal Bonds Risk. Municipal bonds are subject to numerous risks, including higher interest rates, economic recession, deterioration of the municipal bond market, possible downgrades and defaults of interest and/or principal.

Municipal Securities Volatility Risk. The value of the securities held by the trust may be subject to steep declines or increased volatility due to changes in performance or perception of the issuers. The markets for credit instruments, including municipal securities, have experienced periods of extreme illiquidity and volatility.

Term Risk - 15 months. Although this unit investment trust terminates in approximately 15 months, the strategy is long-term. Investors should consider their ability to pursue investing in successive portfolios, if available. There may be tax consequences unless units are purchased in an IRA or other qualified plan.

Additional Risk. For a discussion of additional risks of investing in the trust see the "Risk Factors" section of the prospectus.

Important Note. It is important to note that an investment can be made in the underlying funds directly rather than through the trust. These direct investments can be made without paying the trust's sales charge, operating expenses and organizational costs.

Operational Risk. As the use of Internet technology has become more prevalent in the course of business, the trust has become more susceptible to potential operational risks through breaches in cybersecurity.

You should carefully consider the trust's investment objectives, risks, and charges and expenses before investing. Contact your financial professional or call First Trust Portfolios, L.P. at 1.800.621.1675 to request a prospectus, which contains this and other information about the trust. Read it carefully before you invest.
