<sup>1</sup>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.

<sup>2</sup> The 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 1.68%, 2.43% and 1.43% for Class A shares, Class C shares and Class I shares, respectively, through October 31, 2026. 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 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.

<u>Example</u>: 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:

---

| | | | |
|:---|:---|:---|:---|
| &nbsp;&nbsp;**<u>YEAR</u>** | &nbsp;&nbsp;**Class A** | &nbsp;&nbsp;**Class C** | &nbsp;&nbsp;**Class I** |
| &nbsp;&nbsp;1 | &nbsp;&nbsp;$736 | &nbsp;&nbsp;$246 | &nbsp;&nbsp;$146 |
| &nbsp;&nbsp;3 | &nbsp;&nbsp;$1078 | &nbsp;&nbsp;$762 | &nbsp;&nbsp;$457 |
| &nbsp;&nbsp;5 | &nbsp;&nbsp;$1443 | &nbsp;&nbsp;$1304 | &nbsp;&nbsp;$790 |
| &nbsp;&nbsp;10 | &nbsp;&nbsp;$2467 | &nbsp;&nbsp;$2785 | &nbsp;&nbsp;$1734 |

---

<u>Portfolio Turnover</u>: 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 16% of the average value of its portfolio.

**Principal Investment Strategies**:

The Fund seeks to achieve its investment objective by primarily investing in the publicly-listed equity securities of U.S. and Canadian companies that generate a majority of their cash flow from midstream energy infrastructure activities. The Fund's strategy aims to achieve current income and capital appreciation over the long-term. The Fund may also invest in the equity securities of master limited partnerships ("MLPs") engaged in energy-related businesses. Most of the entities in which the Fund invests derive a majority of their revenue from energy infrastructure-related activities, including treatment, gathering, compression, processing, transportation, transmission, fractionation, storage and terminalling of natural gas, natural gas liquids, crude oil, or refined products. Under normal conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in companies that derive a majority of their revenue from energy infrastructure activities. The Fund may invest in U.S. and foreign issuers of any market capitalization.

The Fund intends to be taxed as a regulated investment company ("RIC") and comply with all RIC-related restrictions, including limiting its investment in entities taxed as limited partnerships, including MLPs, to 25%.

SL Advisors, LLC, the Fund's investment sub-advisor (the "Sub-Advisor"), utilizes an investment selection process that includes the analysis of various qualitative and quantitative factors. In evaluating securities for inclusion in the investment portfolio, the Sub-Advisor considers current distribution yield and likely growth prospects of the issuer of the security. Those issuers with a demonstrated history of stable and growing distributions are favored, as are those with well-regarded management teams. Each issuer's competitive position is also evaluated, as is its new projects, its likelihood of successful execution, and its impact on future distribution growth.

Securities will be sold when other appropriate securities are available with superior return prospects.

The Fund is classified as "non-diversified" for purposes of the Investment Company Act of 1940, as amended (the "1940 Act"), which means that it is not limited by the 1940 Act with regard to the portion of its assets that may be invested in the securities of a single issuer.

*Distribution Policy*: The Fund's distribution policy is to make twelve monthly distributions to shareholders. 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. Shareholders should not assume that the source of a distribution from the Fund is net profit. For more information about the Fund's distribution policy, please turn to "Additional Information About the Fund's Principal Investment Strategies and Related Risks – Principal Investment Strategies – Catalyst Energy Infrastructure Fund Distribution Policy and Goals" section in the Fund's Prospectus.

**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.

**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.

**Energy Sector Risk**. The Fund focuses its investments in the energy infrastructure sector, which historically has been very volatile. Because of its focus in this sector, the performance of the Fund is tied closely to, and affected by, developments in the energy sector, such as the possibility that government regulation will negatively impact companies in this sector. Energy infrastructure entities are subject to the risks specific to the industry they serve, including, but not limited to, the following:

&nbsp;&nbsp;&nbsp;&nbsp;· Fluctuations in commodity prices;

&nbsp;&nbsp;&nbsp;&nbsp;· Reduced volumes of natural gas or other energy commodities available for transporting, processing, storing or distributing;

&nbsp;&nbsp;&nbsp;&nbsp;· New construction risk and acquisition risk, which can limit potential growth;

&nbsp;&nbsp;&nbsp;&nbsp;· A sustained reduced demand for crude oil, natural gas and refined petroleum products resulting from a recession or an increase in
market price or higher taxes;

&nbsp;&nbsp;&nbsp;&nbsp;· Depletion of the natural gas reserves or other commodities if not replaced;

&nbsp;&nbsp;&nbsp;&nbsp;· Changes in the regulatory environment;

&nbsp;&nbsp;&nbsp;&nbsp;· Extreme weather;

&nbsp;&nbsp;&nbsp;&nbsp;· Rising interest rates, which could result in a higher cost of capital and drive investors into other investment opportunities; and

&nbsp;&nbsp;&nbsp;&nbsp;· Threats of attack by terrorists.

**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.

**Foreign Investment Risk**. Foreign investing involves risks not typically associated with U.S. investments, including adverse fluctuations in foreign currency values, adverse political, social and economic developments, less liquidity, greater volatility, less developed or less efficient trading markets, political instability, and differing auditing and legal standards. Foreign companies are generally not subject to the same regulatory requirements as U.S. companies, thereby resulting in less publicly available information about these companies. In addition, foreign accounting, auditing and financial reporting standards generally differ from those applicable to U.S. companies.

**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 market risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels, tariffs or trade wars and political events affect the securities markets.

**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.

**MLP and MLP-Related Securities Risks**. Investments in MLPs and MLP-related securities involve risks different from those of investing in common stock, including risks related to limited control and limited rights to vote on matters affecting the MLP or MLP-related security, risks related to potential conflicts of interest between an MLP and the MLP's general partner, cash flow risks, dilution risks (which could occur if the MLP raises capital and then invests it in projects whose return fails to exceed the cost of capital raised), and risks related to the general partner's limited call right. MLPs and MLP-related securities are generally considered interest-rate sensitive

investments. During periods of interest rate volatility, these investments may not provide attractive returns. Depending on the state of interest rates in general, the use of MLPs or MLP-related securities could enhance or harm the overall performance of the Fund.

**MLP Tax Risk.** Typically, MLPs do not pay U.S. federal income tax at the partnership level. Instead, each partner is allocated a share of the partnership's income, gains, losses, deductions and expenses. A change in current tax law or in the underlying business mix of a given MLP could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which would result in such MLP being required to pay U.S. federal income tax on its taxable income. The classification of an MLP as a corporation for U.S. federal income tax purposes would have the effect of reducing the amount of cash available for distribution by the MLP. Thus, if any of the MLPs owned by the Fund were treated as corporations for U.S. federal income tax purposes, it could result in a reduction of the value of your investment in the Fund and lower income, as compared to an MLP that is not taxed as a corporation.

**Non-diversification Risk**. Because a relatively high percentage of the Fund's assets may be invested in the securities of a limited number of companies that could be in the same or related economic sectors, the Fund's portfolio may be more susceptible to any single economic, technological or regulatory occurrence than the portfolio of a diversified fund.

**Regulatory Risk**. Changes in the laws or regulations of the United States or other countries, including any changes to applicable tax laws and regulations, could impair the ability of the Fund to achieve its investment objective and could increase the operating expenses of the Fund.

**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. The Fund typically focuses its investments in the energy sector and, therefore, is more susceptible to energy sector risk, as described above.

**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.

**Small Capitalization Company Risk**. To the extent the Fund invests in the stocks of smaller-sized companies, the Fund may be subject to additional risks, including the risk that earnings and prospects of these companies are more volatile than larger companies.

**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 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.

**Annual Total Returns**

After-tax returns are calculated using the highest historical individual federal marginal income tax rate and do not reflect the impact of state and local taxes. Actual after-tax returns depend on a shareholder's tax situation and may differ from those shown. After-tax returns are not relevant for shareholders who hold Fund shares in tax-deferred accounts or to shares held by non-taxable

entities. After-tax returns are only shown for Class A shares. After-tax returns for other share classes will vary.

**Advisor**: Catalyst Capital Advisors LLC is the Fund's investment advisor.

**Sub-Advisor**: SL Advisors, LLC is the Fund's investment sub-advisor.

**Portfolio Managers**: Simon Lack, Managing Partner and Chief Compliance Officer of the Sub-Advisor, and Henry Hoffman, Partner of the Sub-Advisor, serve as the Fund's Portfolio Managers and are jointly and primarily responsible for the day-to-day management of the Fund's portfolio. Mr. Lack has served the Fund in this capacity since the Fund commenced operations in 2014. Mr. Hoffman has served the Fund in this capacity since 2021.

**Purchase and Sale of Fund Shares**: The minimum initial investment in each share class of the Fund is $2,500 for a regular account, $2,500 for an IRA account or $100 for an automatic investment plan account. The minimum subsequent investment in the Fund is $50. You may purchase and redeem shares of the Fund on any day that the New York Stock Exchange is open. Redemption requests may be made in writing, by telephone or through a financial intermediary to the Fund or the Transfer Agent and will be paid by check or wire transfer.

**Tax Information**: Dividends and capital gain distributions you receive from the Fund, whether you reinvest your distributions in additional Fund shares or receive them in cash, are taxable to you at either ordinary income or capital gains tax rates, unless you are investing through a tax-deferred plan such as an IRA or 401(k) plan. If you are investing through a tax-deferred plan, distributions may be taxable upon withdrawal from the plan.

**Payments to Broker-Dealers and Other Financial Intermediaries**: If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. 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.
