FUND SUMMARY: CATALYST/LYONS TACTICAL ALLOCATION FUND

Investment Objective: The Fund's investment objective is long-term capital appreciation.

¹The 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.

²The Fund's investment advisor, Catalyst Capital Advisors LLC (the "Advisor"), has contractually agreed to waive advisory 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 1.53%. 2.28% and 1.28% for Class A shares, Class C shares and Class I shares, respectively, for all share classes through October 31, 2025. This agreement may only be terminated by the Board of Trustees 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 the lesser of: (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, 2025, 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	$722	$231	$130
3	$1,141	$831	$520
5	$1,586	$1,457	$935
10	$2,815	$3,144	$2,093

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, 2024 was 17% of the average value of its portfolio.

Principal Investment Strategies:

The Fund seeks to achieve its investment objective by combining a tactical allocation process intended to offer downside protection during significant market declines, with individual stock selection. Lyons Wealth Management, LLC, the Fund's investment sub-advisor (the "Sub-Advisor"), uses a proprietary quantitative risk model that seeks to remain fully invested in equities continuously, during bull market conditions, and to shift defensive only during sustained periods of heightened equity market risk. This binary model is intended to identify extended time periods over which risk levels are anticipated to remain either acceptable for owning stocks or elevated above the expected reward.

Asset allocation between stocks or bonds is determined monthly based on the risk model's binary output. A positive reading generally indicates that long-term market risk remains at a level the Sub-Advisor believes is currently acceptable for owning stocks, and results in a portfolio allocation to equities. A negative reading indicates that market risk has reached levels the Sub-Advisor believes are typically indicative of long-term, significant market declines, and results in a portfolio shift to fixed income securities. The portfolio may shift allocation at any point during the quarter, but generally reallocation only occurs upon the systematic month-end signal readings. The Sub-Advisor anticipates that the model may sustain a given signal for extended periods of time, potentially for multi-year periods.

The portfolio's default allocation is to equities. While maintaining equity exposure, the Sub-Advisor invests in a concentrated portfolio of stocks selected for earnings efficiency, company strength, and relative value. Stock selection is based on the Sub-Advisor's proprietary ranking model that ranks stocks according to fundamental criteria. The Fund invests in U.S. listed mid-cap, large-cap and mega-cap companies. While maintaining an equity allocation, the portfolio is reconstituted and rebalanced quarterly.

The Fund's defensive portfolio consists of fixed income securities. Securities are selected for investment based on yields, prices, yield to maturity, duration and risk. The Fund may invest in

domestic, investment-grade fixed income securities of any duration and maturity, but it generally will invest in short-term and intermediate-term U.S. Treasury bills and notes with one to ten years to maturity at the time of issuance. These fixed income positions are sold when the risk model produces a positive signal, and a new equity portfolio is established based on an updated stock selection model ranking.

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 the value of the Fund and your investment.

Allocation Risk. The risk that if the Fund's strategy for allocating assets among different assets classes does not work as intended, the Fund may not achieve its objective or may underperform other funds with the same or similar investment strategy.

Equity Security Risk. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. Investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction and global or regional political, economic and banking crises.

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. 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.

Large Capitalization Company Risk. The Fund may invest in large capitalization companies. The securities of such companies may underperform other segments of the market because such companies may be less responsive to competitive challenges and opportunities and may be unable to attain high growth rates during periods of economic expansion.

Management Risk. The portfolio managers' judgments about the attractiveness, value and potential appreciation of particular stocks or other 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 stock 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.

Mega Capitalization Company Risk. The securities of mega capitalization companies may underperform securities of smaller companies because such companies may be slow to respond to competitive challenges and growth opportunities.

Medium (Mid) Capitalization Company Risk. The earnings and prospects of mid-capitalization companies are more volatile than larger companies, they may experience higher failure rates than larger companies and normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures.

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Sub-Advisor carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons including errors, omissions, imperfections or malfunctions. Because the use of models are usually based on data supplied by third parties, the success of the Sub-Advisor's use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

Sector Exposure Risk. Sector exposure risk is the possibility that securities within the same sector will decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns.

Industrials Sector Risk. The value of securities issued by companies in the industrials sector may be adversely affected by supply and demand related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector.

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

U.S. Agency Securities Risk. The Fund may invest in U.S. government or agency obligations. Securities issued or guaranteed by federal agencies and U.S. government sponsored entities may or may not be backed by the full faith and credit of the U.S. government.

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 performance of the Fund's Class A shares for each of the last ten full calendar years. Although Class C and Class I shares have similar annual returns to Class A shares because the classes are invested in the same portfolio of securities, the returns for Class C and Class I shares are different from Class A shares because Class C and Class I shares have different expenses than Class A shares. The performance table shows how the average returns of the Class A, C, and I shares compare over time with those of a broad-based market index and a supplemental index. Sales charges are reflected in the information shown below 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. Updated performance information is available at no cost by calling 1-866-447-4228 and on the Fund's website at www.CatalystMF.com.
