Before you invest, you may want to review the Fund’s complete prospectus, which contains more information about the Fund and its risks. You can find the Fund’s prospectus and other information about the Fund at www.eventidefunds.com. You can also get this information at no cost by calling 1-877-771-3836, emailing info@eventidefunds.com or by asking any financial intermediary that offers shares of the Fund. The Fund’s prospectus and statement of additional information, both dated November 1, 2026, are incorporated by reference into this summary prospectus and may be obtained, free of charge, at the website or phone number noted above.

Investment Objective. The Eventide Core Bond Fund’s (the “Core Bond Fund” or the “Fund”) investment objective is total return consistent with income generation.

Fees and Expenses of the Fund. The tables describe the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund (“Fund shares” or “Shares”). 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 118 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 70, and Waivers of Up-Front Sales Charge on Class A Shares on page 71.

Example of Hypothetical Fund Costs. 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, 2027, 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:

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 rate 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, 2026, was 23% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its objective through investments in income-producing securities issued by entities deemed by the Fund’s investment adviser, Eventide Asset Management, LLC (“Eventide” or the “Adviser”), to be serving well the needs of customers, employees, suppliers, communities, the environment, and society broadly using the Adviser’s faith-based screening criteria as more fully described below under “Faith-Based Screening.” Income producing securities that the Fund may invest in include, but are not limited to, corporate bonds; preferred stocks, convertible debt and other hybrid securities that have debt and equity characteristics but are predominantly debt in nature; agency and non-agency residential and commercial mortgage-backed securities; asset-backed securities (including auto loans and leases, equipment loans and leases, and credit cards); green bonds (i.e., bonds that allow issuers to use proceeds for environmental projects); social bonds (i.e., bonds that allow issuers to use proceeds for social projects); sustainable bonds (i.e., bonds that are a combination of green and social bonds); government agency debt instruments; and municipal bonds (collectively, “Bonds”). Under normal circumstances, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in Bonds.

The Fund may invest in Bonds of any maturity and, under normal market conditions, the Bonds held by the Fund have a weighted average duration between three years and nine 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 approximately a 5% decline in the bond’s price. If a bond has a duration of 10 years, a 1% rise in interest rates would result in approximately a 10% decline in the bond’s price. The Fund invests predominantly in investment grade securities. With respect to both fixed income and equity securities, the Fund may invest in the securities of foreign entities and may invest in companies of any market capitalization. The Fund may invest in private and other issuers whose securities may have

legal or contractual restrictions on resale or are otherwise illiquid (“Illiquid Investments”), which can impact their valuation. The Fund will not invest more than 15% of the Fund’s net assets in Illiquid Investments.

Faith-Based Screening. The Adviser uses its proprietary screening methodology to analyze all potential investments for the company’s ability to operate with integrity and to create value for customers, employees, and other stakeholders by reflecting the values described below. The values assessed in the Adviser’s screening process are inspired by the Christian faith and rooted in a biblical worldview. While few companies may reach these ideals in every area of their business, these principles articulate the Adviser’s highest expectations for the companies in which the Fund invests. The Adviser uses its screening process in connection with other fundamental research processes to establish the Fund’s eligible investment universe. Securities are generally ineligible within the Fund’s portfolio unless the Adviser believes that the faith-based screens are met. If the Adviser’s research identifies events and/or business changes suggesting that a portfolio company no longer meets the faith-based criteria, the Fund may hold the company’s securities while the Adviser performs additional research, including possible direct engagement with the company to assess practices. The Adviser’s faith-based screening process for potential investments does not apply relative weights between values-based factors and financial factors. There is no guarantee that the Adviser will be able to successfully screen out all companies that are inconsistent with the following principles which help to guide the Adviser’s research and investment framework. Specifically, the Adviser seeks to invest in companies that reflect the following values:

The Adviser applies a combination of methods within its fundamental research process and systems to help cover a range of company-related information. This includes qualitative and quantitative data that can inform the Adviser’s investment decisions, such as company reports, news and research offered by third parties. This information can reflect on a company’s financial and competitive position, risks, and business reputation and ethical standing in the marketplace. The Adviser typically obtains values-based data from multiple third-party providers, which the Adviser changes from time to time based on research needs and industry developments. Values-based data offers additional inputs to the Adviser’s fundamental research process and investment framework. The Adviser views third-party information as part of its overall research rather than assigning any particular data source as the determinative factor in investment decisions. The Adviser believes that considering a broad range of research information, from multiple sources, can help to mitigate risks associated with misinterpreting data or relying on inaccurate information

provided by third parties, but cannot guarantee that any third-party information it receives is accurate or free of defects. The Adviser maintains research supporting its investment decisions.

Consistent with the Adviser’s values, the Fund may invest in domestic and/or foreign fixed-income securities, such as notes (including standalone notes not rated by any agency), to help fund community development institutions and projects aimed at serving human needs such as those of low-to-moderate income families and communities.

Investments that meet the Adviser’s faith-based criteria are analyzed by the Fund’s investment sub-adviser, Boyd Watterson Asset Management, LLC (the “Sub-Adviser”) for possible inclusion in the Fund’s portfolio. The Sub-Adviser builds the Fund’s portfolio based on macroeconomic trends and forecasts in economic growth, inflation expectations, and monetary policy. The Sub-Adviser strives to generate excess return through sector allocation (adjusting allocations across major sectors of the bond market based on assessments of fundamentals and current versus historical valuation relationships), duration management (holding securities to optimize interest rates), yield curve positioning (adjusting holdings to capitalize on expected changes in the Treasury yield curve), and security selection. The ability of the Sub-Adviser to deliver returns varies according to the economic and market environment. The Sub-Adviser’s methods are intended to accumulate value over a full market cycle.

Securities may be sold when the Adviser or the Sub-Adviser believes that they no longer represent relatively attractive investment opportunities or when the Adviser believes the underlying company’s practices are no longer consistent with the Adviser’s faith-based values.

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.

Asset-Backed and Mortgage-Backed Security Risk. When the Fund invests in asset-backed securities, mortgage-backed securities or collateralized mortgage obligations, 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.

Commercial mortgage-backed securities (“CMBS”) are subject to credit risk because underlying loan borrowers may default. Subordinate tranches of CMBS are more sensitive to defaults. Previously non-defaulting borrowers may not be able to refinance their loans when due, resulting in higher default rates. CMBS, in general, may become illiquid.

Recently, hospitality, retail, and office properties have become subject to heightened vacancy rates and an accompanying increase in the risk of default.

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. An issuer of a security may fail to pay principal and interest in a timely manner, reducing the Fund’s total return. The Fund may invest in high-yield, unrated or otherwise 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.

Duration Risk. Longer-term securities may be more sensitive to interest rate changes. Rising interest rates pose a heightened risk to the Fund’s longer-term fixed income securities. Effective duration estimates price changes for relatively small changes in rates. If rates increase significantly, effective duration may tend to understate the drop in a security’s price. If rates drop significantly, effective duration may tend to overstate the increase in a security’s price.

Ethical Investment Risk. The Fund’s ethical values screening criteria could cause it to underperform similar funds that do not have such screening criteria. This could be due to ethically acceptable companies falling out of favor with investors or failing to perform as well as companies that do not meet the Fund’s ethical screening guidelines.

To supplement its efforts in ethical investing, the Adviser may engage with portfolio companies to encourage consideration of corporate strategies aligned with the Adviser’s values, including pricing and/or business practices that may be beneficial within particular industries. The Adviser believes these activities will help promote ethical and effective corporate governance and long-term strategy for companies, and potentially create a positive effect on the particular businesses and/or industries, their consumers, and the Fund. There is no guarantee that the Adviser’s corporate engagements and related-activities will achieve their intended results. There is a risk that the Adviser’s activities in this regard could limit the Fund’s investment universe and reduce the amount of profits that could be realized by affected companies, limiting the Fund’s investment returns. Furthermore, the U.S. government or any agency thereof, may enact rules or legislation that, directly or indirectly, materially impacts the Adviser’s activities in this regard, or materially affects the value of companies or opportunities for investment within particular industries.

Extension Risk. If interest rates increase, repayments of principal on certain debt securities, including, but not limited to, floating rate loans and mortgage-related securities, may occur at a slower rate than expected and the expected maturity of those securities could lengthen as a result. Securities that are subject to extension risk generally have a greater potential for loss when prevailing interest rates increase, which could cause their values to fall sharply.

Fixed Income Risk. When the Fund invests in fixed income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase 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), extension risk (an issuer may exercise its right to repay

principal on a fixed rate obligation held by the Fund later than expected), 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.

Foreign Securities Risk. Since the Fund’s investments may include foreign securities, the Fund is subject to risks beyond those associated with investing in domestic securities. The value of foreign securities is subject to currency fluctuations. 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 investing involves other risks not typically associated with U.S. investments, including adverse political, social and economic developments, less liquidity, greater volatility, less developed or less efficient trading markets, political instability and differing accounting, auditing, financial reporting and legal standards.

Income Risk. The income from the Fund’s portfolio may decline because of falling market interest rates. This can result when the Fund invests the proceeds from new share sales, or from matured or called bonds, at market interest rates that are below the portfolio’s current earnings rate.

Interest Rate Risk. Changes in short-term market interest rates will directly affect the yield on the shares of a fund whose investments are normally invested in floating rate debt. If short-term market interest rates fall, the yield on the Fund’s shares will also fall. Conversely, when short-term market interest rates increase, because of the lag between changes in such short-term rates and the resetting of the floating rates on the floating rate debt in the Fund’s portfolio, the impact of rising rates will be delayed to the extent of such lag. Rising interest rates pose a heightened risk to any longer-term fixed income securities held by the Fund.

Large Capitalization Company Risk. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

Liquidity Risk. Some investments held by the Fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid investments may also lack a readily observable or market-corroborated price and 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 an unexpected loss.

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 stock or bond market risks may also affect the value of the Fund. Factors such as domestic and/or foreign economic growth and market conditions, interest rate levels, political events and terrorism affect the securities markets.

Medium (Mid) Capitalization Company Risk. To the extent the Fund invests in the securities of mid-sized companies, the Fund may be subject to additional risks. The earnings and prospects of these companies are more volatile than

larger companies. These companies may experience higher failure rates than larger companies. Mid-sized companies 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. Mid-sized companies may also have limited markets, product lines or financial resources and may lack management experience.

Municipal Bond Risk. The value of municipal bonds may fluctuate as a result of changes in the cash flows generated by the revenue source(s), changes in the priority of the municipal obligation to receive the cash flows generated by the revenue source(s), or changes in federal tax laws or the activity of an issuer which may adversely affect the tax-exempt status of municipal bonds.

Preferred Stock Risk. Dividends on preferred stocks are generally payable at the discretion of the issuer’s board of directors and Fund shareholders may lose money if dividends are not paid. Preferred stock prices may fall if interest rates increase or the issuer’s creditworthiness becomes impaired. Preferred 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.

Prepayment Risk. The Fund may invest in debt securities that may be paid off early when the issuer of a debt security can repay the principal prior to a security’s maturity. If interest rates are falling, the Fund may have to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund’s income.

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. There can be no guarantee the securities held by the Fund will appreciate in value.

Small Capitalization Company Risk. Smaller-sized companies 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 and companies may have limited markets, product lines or financial resources and lack management experience.

Sovereign Debt Risk. Investment in sovereign debt obligations involves special risks not present in corporate debt obligations. The issuer of the sovereign debt or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Fund may have limited recourse in the event of a default.

U.S. Government Obligations Risk. The Fund’s investments in 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 its Class A Shares for each full calendar year since the Fund’s Class A Shares commenced operations. Although Class C, N and 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, N and I Shares are different from Class A Shares because Class C, N and I Shares have different expenses than Class A Shares. The performance table shows how the average annual returns of Class A, C, I and N Shares compare over time with a broad-based market index. 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 1-877-771-3836 and on the Fund’s website at www.eventidefunds.com.

Figures do not reflect sales charges. If they did, returns would be lower.

During the period shown in the bar chart, for the Class A Shares, the highest return for a quarter was 6.46% (quarter ended December 31, 2023), and the lowest return for a quarter was (6.31)% (quarter ended March 31, 2022). The Fund’s Class A year-to-date return as of September 30, 2026, was (3.64)%.

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, which are not shown, will vary from those of Class A Shares.
