FUND SUMMARY: CATALYST ENHANCED INCOME STRATEGY FUND

Investment Objective: The Fund's investment objective is current income.

Fees and Expenses of the Fund: This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. You may qualify for sales charge discounts on purchases of Class A shares if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund. More information about these and other discounts is available from your financial professional and is included in the section of the Fund's prospectus entitled How to Buy Shares on page 101 and Appendix A - Intermediary-Specific Sales Charge Reductions and Waivers, and in the sections of the Fund's Statement of Additional Information entitled Reduction of Up-Front Sales Charge on Class A Shares on page 64 and Waiver of Up-Front Sales Charge on Class A Shares on page 65.

¹ The 1.00% maximum deferred sales charge may be assessed in the case of investments at or above the $1 million breakpoint (where you do not pay an initial sales charge) on shares redeemed within two years of purchase.

² Acquired Fund Fees and Expenses are the indirect costs of investing in other investment companies. The total annual fund operating expenses in this fee table will not correlate to the expense ratio in the Fund's financial highlights because the financial statements include only the direct operating expenses incurred by the Fund, not the indirect costs of investing in other investment companies.

³ The Fund's investment advisor, Catalyst Capital Advisors LLC (the "Advisor"), has contractually agreed to waive management fees and/or reimburse expenses of the Fund to the extent necessary to limit total annual fund operating expenses (excluding brokerage costs; borrowing costs, such as (a) interest, and (b) dividends on securities sold short; taxes; underlying fund expenses; and extraordinary expenses, such as regulatory inquiry and litigation expenses) at 1.75%, 2.50% and 1.50% for Class A shares, Class C shares and Class I shares, respectively, through October 31, 2026. This agreement may be terminated by the Fund's Board of Trustees only on 60 days' written notice to the Advisor, by the Advisor with the consent of the Board of Trustees, or upon the termination of the investment advisory agreement between the Trust and the Advisor. Fee waivers and expense reimbursements are subject to possible recoupment by the Advisor from the Fund in future years on a rolling three-year basis (within the three years after the fees have been waived or reimbursed) so long as such recoupment does not cause the Fund's expense ratio (after the repayment is taken into account) to exceed both: (i) the Fund's expense limitation at the time such expenses were waived, and (ii) the Fund's current expense limitation at the time of recoupment.

Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then hold or redeem all of your shares at the end of those periods. The Example only accounts for the Fund's expense limitation in place through its expiration period, October 31, 2026, and then depicts the Fund's total annual expenses thereafter. 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:

YEAR	Class A	Class C	Class I
1	$645	$254	$154
3	$1,066	$847	$545
5	$1,513	$1,466	$961
10	$2,747	$3,134	$2,122

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 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 portfolio turnover rate of the Fund for the fiscal year ended June 30, 2025 was 18% of the average value of its portfolio.

Principal Investment Strategies:

The Fund seeks to achieve its investment objective by primarily investing in agency and non-agency commercial and residential mortgage-backed securities ("MBS") and other fixed income asset-backed securities, including securities backed by aircraft, automobiles, credit card receivables, and student loans.

The Fund does not limit its investments to a particular credit quality and may invest in distressed asset backed securities and other below investment grade securities (commonly referred to as "junk") without limitation. Below investment grade securities are those rated below Baa3 by Moody's Investor Services or equivalently by another nationally recognized statistical rating organization, as well as non-rated securities. The MBS in which the Fund invests are generally liquid; in other words, they can be sold at approximately the current market value within 7 calendar days. The Fund may hold up to 15% of its net assets in illiquid investments. In managing the Fund's investments, the Fund's sub-advisor, Wynkoop, LLC (the "Sub-Advisor"), seeks to construct an investment portfolio with a weighted average maturity that ranges between 1 and 10 years and a weighted average effective duration that ranges between -9 and 9 years. Duration is a measure of the expected life of a fixed income instrument that is used to determine the sensitivity of a security's price to changes in interest rates. Effective duration is a measure of the Fund's portfolio duration adjusted for the anticipated effect of interest rate changes on bond and mortgage pre-payment rates. The longer a security's duration, the more sensitive it will be to changes in interest rates. The more sensitive a security is to changes in interest rates, the higher its volatility risk. For example, if a bond has a duration of 5 years, a 1% rise in rates would result in a 5% decline in share price. If a bond has a duration of 10 years, a 1% rise in interest rates would result in a 10% decline in share price. Unique to the residential MBS market are securities, such as interest-only securities, and related derivatives, that have "negative duration." This means that the value of these instruments normally increases with

higher interest rates, the opposite of most other debt instruments. This generally allows some portion of the Fund's market risk to be hedged with a purchase, rather than a short sale, and allows the Fund to realize positive cash flows on the hedge as a result of interest received with respect to that security.

The Sub-Advisor determines the allocation of the Fund's investments across the various fixed income asset classes based on market supply and which asset classes it views as offering the best risk-adjusted values in the marketplace at a given time. However, the Fund expects to focus its investments in agency and non-agency commercial and residential MBS and, under normal circumstances, invests over 25% of its assets in agency and non-agency commercial and residential MBS. In selecting individual securities for investment by the Fund, the Sub-Advisor selects securities that it believes offer the best risk/return opportunity based on its analyses of a variety of factors, including collateral quality, duration, structure, excess interest, credit support, potential for greater upside, and less downside, capture, liquidity and market conditions, and favors undervalued investments that produce consistent returns in most interest rate environments. The Sub-Advisor attempts to diversify geographically and among the servicing institutions that service or originate the MBS.

Distribution Policy. The Fund's distribution policy is to make twelve monthly distributions to shareholders. The level of monthly distributions (including any return of capital) is not fixed and is not designed to generate, and is not expected to result in, distributions that equal a fixed percentage of the Fund's current net asset value per share. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital. Shareholders should not assume that the source of a distribution from the Fund is net profit.

Principal Risks of Investing in the Fund:

As with any mutual fund, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund's net asset value and returns will vary and you could lose money on your investment in the Fund, and those losses could be significant.

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, total return, and value of the Fund and your investment.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to sell. Although most of the Fund's securities must be liquid at the time of investment, the Fund may purchase illiquid investments and securities may become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the Fund's investments may be harder to value, especially in changing markets, and if the Fund is forced to sell these investments to meet redemptions or for other cash needs, the Fund may suffer a loss. In addition, when there is illiquidity in the market for certain securities, the Fund, due to limitations on investments in illiquid investments, may be unable to achieve its desired level of exposure to a certain sector. Some investments held by the Fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid investments may also be difficult to value. If the

Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the Fund may be forced to sell at a loss.

Asset-Backed and Mortgage-Backed Security Risk. When the Fund invests in asset-backed securities, mortgage-backed securities or CMOs, the Fund is subject to the risk that, if the issuer fails to pay interest or repay principal, the assets backing these securities may not be sufficient to support payments on the securities.

Mortgage-backed securities represent participating interests in pools of residential mortgage loans, some of which are guaranteed by the U.S. government, its agencies or instrumentalities. However, the guarantee of these types of securities relates to the principal and interest payments and not the market value of such securities. In addition, the guarantee only relates to the mortgage-backed securities held by a Fund and not the purchase of shares of the Fund. Mortgage-backed securities do not have a fixed maturity, and their expected maturities may vary when interest rates rise or fall.

Mortgage-backed securities issued or guaranteed by private issuers are also known as "non-agency MBS." Non-agency MBS generally are a greater credit risk than MBS issued by the U.S. government, and the market for non-agency MBS is smaller and may be less liquid that the market for government MBS.

Credit Risk. Credit risk is the risk that an issuer of a security will fail to pay principal and interest in a timely manner, reducing the Fund's total return. The Fund may invest in high-yield, high-risk securities, commonly called "junk bonds," that are not investment grade and are generally considered speculative because they present a greater risk of loss, including default, than higher quality debt securities. Credit risk may be substantial for the Fund.

Distribution Policy Risk. The Fund may, at the discretion of management, target a specific level of monthly distributions (including any return of capital) from time to time. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital (i.e., from your original investment). Shareholders should not assume that the source of a distribution from the Fund is net profit. Shareholders should note that return of capital will reduce the tax basis of their shares and potentially increase the taxable gain, if any, upon disposition of their shares.

Duration Risk. Longer-term securities may be more sensitive to interest rate changes. Given the potential for increases in those rates, a heightened risk is posed by rising interest rates to a fund whose portfolios include longer-term fixed income securities.

Fixed Income Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which

could cause the value of the Fund's investments and share price to decline. Other risk factors include credit risk (the debtor may default) and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund's share price and total return to be reduced and fluctuate more than other types of investments.

Industry Concentration Risk. A fund that concentrates its investments in an industry or group of industries is more vulnerable to adverse market, economic, regulatory, political or other developments affecting such industry or group of industries than a fund that invests its assets more broadly.

Interest Rate Risk. Overall bond prices, including the prices of securities held by the Fund, may decline over short or even long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. For example, if interest rates go up by 1.0%, the price of a 4% coupon bond will decrease by approximately 1.0% for a bond with 1 year to maturity, and approximately 4.4% for a bond with 5 years to maturity. The maturity and effective duration of the Fund's investment portfolio may vary materially from its target, from time to time, and there is no assurance that the maturity or effective duration of the Fund's investment portfolio will not exceed its target. Rising interest rates pose a heightened risk to any longer-term fixed income securities held by the Fund.

Junk Bond Risk. Lower-quality bonds, known as "high yield" or "junk" bonds, present greater risk than bonds of higher quality, including an increased risk of default, illiquidity of the instrument, and changes in value based on public perception of the issuer. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce the Fund's ability to sell its bonds. The lack of a liquid market for these bonds could decrease the Fund's share price.

Management Risk. The portfolio managers' judgments about the attractiveness, value and potential appreciation of particular securities in which the Fund invests may prove to be incorrect, and there is no guarantee that the portfolio managers' judgment will produce the desired results.

Market Risk. Overall market risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels, and political events affect the securities markets.

Prepayment and Extension Risk. Prepayment risk is the risk that principal on a debt obligation may be repaid earlier than anticipated. Extension risk is the risk that principal on a fixed rate obligation held by the Fund may be repaid later than anticipated. Both prepayment and extension risks may impact the Fund's profits.

Real Estate Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations, and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These may include decreases in real estate values, overbuilding, rising operating costs, interest rates, and

property taxes. In addition, some real estate-related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects.

Security Risk. The value of the Fund may decrease in response to the activities and financial prospects of an individual security or group of securities in the Fund's portfolio.

Sub-Prime Mortgage Risk. Lower-quality notes, such as those considered "sub-prime," are more likely to default than those considered "prime" by a rating evaluation agency or service provider. An economic downturn or period of rising interest rates could adversely affect the market for sub-prime notes and reduce the Fund's ability to sell these securities. The lack of a liquid market for these securities could decrease the Fund's share price. Additionally, borrowers may seek bankruptcy protection which would delay resolution of security holder claims and may eliminate or materially reduce liquidity. Subprime mortgages are riskier, and potentially less liquid, than mortgage-backed securities.

Performance:

The bar chart and accompanying table shown below provide an indication of the risks of investing in the Fund. The bar chart shows the total return of its Class A shares for each full calendar year since inception. Class C shares and Class I shares have similar annual returns to Class A shares because they are invested in the same portfolio of securities; however, the returns for Class C shares and Class I shares are different from Class A shares because Class C shares and Class I shares have different expenses than Class A shares. The performance table shows average annual total returns for Class A, Class C and Class I shares and how their average annual returns compare over time with those of a broad-based market index and a supplemental index. Sales charges are reflected in the information shown in the table, but the information shown in the bar chart does not reflect sales charges, and, if it did, returns would be lower. How the Fund has performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future.

The Fund's returns in the first quarter of 2019 may not be achievable going forward as the Fund's assets grow. The active trading strategy of the Fund had a significant impact on returns from launch date, especially when depicted as a percentage. The gains from individual trades had a magnified effect on NAV as a result of the small initial launch capital. As the assets grow, the denominator becomes larger, and thus individual trades do not necessarily have as much of an impact on returns. The Sub-Advisor continues to deploy its active trading approach, which seeks to take advantage of market inefficiencies and dislocations.
