Fund Summary: Eventide Large Cap Focus ETF

Investment Objective: The Eventide Large Cap Focus ETF (the “Large Cap Focus ETF” or the “Fund”) seeks to provide long-term capital appreciation.

Fees and Expenses: This table describes 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.

⁽¹⁾ The management fee is structured as a “unified fee,” from which the Fund’s adviser pays all routine expenses of the Fund, except for the Fund’s management fee; payments under any 12b-1 plan; taxes; brokerage commissions and trading costs; interest (including borrowing costs and overdraft charges); short sale dividends and interest expenses; acquired fund fees and expenses; litigation expenses and indemnification obligations; and non-routine or extraordinary expenses of the Fund (such as reorganizational costs), each of which is paid by the Fund.

⁽²⁾ Estimated for the current fiscal year.

Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then either hold or sell all of your Shares at the end of those periods. This Example does not reflect the effect of brokerage commissions or other transaction costs you pay in connection with the purchase or sale of Fund shares. 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. Because the Fund has not commenced operations as of the date of this Prospectus, the Fund has not yet had any portfolio turnover. In the future, the portfolio turnover rate for the most recent fiscal year will be provided here.

Principal Investment Strategy: The Fund seeks to achieve its investment objective by primarily investing in a broad range of equity securities of large capitalization companies. The Fund’s investment adviser, Eventide Asset

Management, LLC (“Eventide” or the “Adviser”), utilizes a fundamental “bottom-up” analysis to evaluate investments for inclusion in the Fund’s portfolio and seeks to identify and invest the Fund’s assets in companies capable of sustaining and/or increasing profitability and/or revenue growth and that serve 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.” Equity securities that the Fund may invest in include, but are not limited to, common stocks (including American Depositary Receipts (“ADRs”)), yieldcos, (e.g., dividend growth-oriented public companies created by a parent company, which bundles renewable and/or conventional long-term contracted operating assets, such as solar and wind power, in order to generate cash flow), real estate investment trusts (“REITs”), convertible bonds, preferred stocks, and master limited partnerships (“MLPs”). Under normal market conditions, the Fund invests at least 80% of its net assets (plus the amount of borrowings for investment purposes) in large capitalization companies. The Fund considers its investment in derivatives, based on their marked to market value, when determining its compliance with this test. Large capitalization companies are defined as companies with market capitalizations at the time of purchase in the range of those market capitalizations of companies included in the Bloomberg U.S. 500 Total Return Index, afloat market-capitalization-weighted index of the 500 most highly capitalized U.S. companies, with dividends reinvested. The capitalization range of the Index is between $2.98 billion and $4.84 trillion as of June 30, 2026. The size of the companies included in the Index will change with market conditions.

The Fund may invest without limitation in securities in companies domiciled outside the United States either directly or through ADRs. The Fund may invest a substantial portion of its assets in the stock of companies in one or more sectors of the economy, such as the technology, industrial, consumer discretionary and healthcare sectors.

The Fund may invest in private companies and other companies whose shares 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. The Adviser may use options strategies, such as puts and covered calls on individual securities, as well as options on securities indices, to generate income, to reduce portfolio volatility, or to reduce downside risk when the Adviser believes adverse market, political or other conditions are likely. The Adviser may also utilize a combination of puts and/or calls on the same security (sometimes referred to as “straddles,” “collars” or “spreads”) or utilize puts and calls on related securities.

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.

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

Principal Investment Risks

As with any ETF, 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 (“NAV”), market price and returns will vary, and you could lose money on your investment in the Fund and those losses could be significant. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The following identifies the principal risks of investing in the Fund. These risks could adversely affect the NAV, market price, total return and the value of the Fund and your investment.

ADRs Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in

investments in U.S. companies. Although an ADR is priced in U.S. dollars, movements in the exchange rate of the local currency versus the U.S. dollar are automatically reflected in the price of the ADR in U.S. dollars. Therefore, even if the price of the foreign security does not change on its market, if the exchange rate of the local currency relative to the U.S. dollar declines, the ADR price would decline by a similar measure.

Authorized Participant Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. An “Authorized Participant” is a participant in the Continuous Net Settlement System of the National Securities Clearing Corporation or the Depository Trust Company (“DTC”) and that has executed a Participant Agreement with the Fund’s distributor (“Distributor”). To the extent these Authorized Participants exit the business or are unable to process creation and/or redemption orders and no other Authorized Participant is able to step forward to process creation and/or redemption orders, in either of these cases, Shares of the Fund may trade like closed-end fund shares at a discount to NAV and possibly face delisting by NYSE Arca, Inc. (the “Exchange”). These risks could cause intra-day bid/ask spreads for the Fund’s shares to widen.

Equity Security Risk. 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. Warrants and rights may expire worthless if the price of a common stock is below the conversion price of the warrant or right. Convertible bonds may decline in value if the price of a common stock falls below the conversion price. 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.

ETF Structure Risks. The Fund is structured as an ETF and as a result is subject to special risks, including:

Not Individually Redeemable. Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.” You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit. Fund shares are typically bought and sold in the secondary market and investors typically pay brokerage commissions or other charges on these transactions.

Trading Issues. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. An active trading market for the Fund’s shares may not be developed or maintained. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares.

Market Price Variance Risk. Individual Shares of the Fund that are listed for trading on the Exchange can be bought and sold in the secondary market at market prices. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV and intra-day bid/ask spreads may widen.

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.  

Foreign Securities Risk. Since the Fund’s investments may include ADRs and 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.

Growth Stock Risk. “Growth” stocks can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks. “Growth” stocks also tend to be more expensive relative to their earnings or assets compared to other types of stocks. As a result, “growth” stocks tend to be sensitive to changes in their earnings and more volatile in price than the stock market as a whole. In addition, companies that the Adviser believes have significant growth potential are often companies with new, limited or cyclical product lines, markets or financial resources and the management of such companies may be dependent upon one or a few key people. The stocks of such companies can therefore be subject to more abrupt or erratic market movements than stocks of larger, more established companies or the stock market in general.

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.

Limited History of Operations Risk. The Fund is a new fund with limited history of operations for investors to evaluate.

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.

MLP and MLP-Related Securities Risk. 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. During periods of rising interest rates, the use of MLPs or MLP-related securities could hinder the overall performance of the Fund.

MLP Tax Risk. MLPs, typically, 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.

Options Market Risk. Markets for options and options on futures may not always operate on a fair and orderly basis. At times, prices for options and options on futures may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances. The dysfunction and manipulation of volatility and options markets may make it difficult for the Fund to effectively implement its investment strategy and achieve its objectives and could potentially lead to significant losses.

Options Risk. There are risks associated with the sale and purchase of call and put options. As the seller (writer) of a covered call option, the Fund assumes the risk of a decline in the market price of the underlying security below the purchase price of the underlying security less the premium received and gives up the opportunity for gain on the

underlying security above the exercise option price because the Fund will no longer hold the underlying security. The seller of an uncovered call option assumes the risk of a theoretically unlimited increase in the market price of the underlying security above the exercise price of the option. The seller of an uncovered put option assumes the risk of a decline in the market price of the underlying security below the exercise price of the option. The buyer of a put option assumes the risk of losing his entire premium invested in the put option. The use of derivative instruments, such as options, involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments, including the risk that the counterparty to an options transaction may not fulfill its contractual obligations.

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 rise or the issuer’s creditworthiness becomes impaired.

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.

REIT Risk. The Fund’s investments in REITs are subject to the same risks as direct investments in real estate, including sensitivity to general economic downturns and the volatility of local real estate markets. REITs may have limited financial resources and their securities may trade infrequently and in limited volume, and thus may be more volatile than other securities. The liquidity of REITs may change dramatically over time.

Sector Exposure Risk. The Fund may focus its investments in securities of a particular sector. Economic, legislative or regulatory developments may occur that significantly affect the sector. This may cause the Fund's net asset value to fluctuate more than that of a fund that does not focus in a particular 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, trade policies, 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. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Healthcare & Life Sciences Sector Risk. Companies in the healthcare and life sciences sectors may be heavily dependent on clinical trials with uncertain outcomes and decisions made by the governments and regulatory authorities. Further, these companies are dependent on patent protection, and the expiration of patents may adversely affect the profitability of the companies. Additionally, the profitability of some healthcare and life sciences companies may be dependent on a relatively limited number of products, and their products can become obsolete due to sector innovation, changes in technologies or other market developments.

Industrial Sector Risk. Industrial companies are affected by supply and demand both for their specific product or service and for industrial sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies.

Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Investments in this sector can be highly volatile. Their values may be adversely affected by such factors as, for example, rapid technological change, changes in management personnel, changes in the competitive environment, and changes in investor sentiment.

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.

Semiconductor Industry Risk. Semiconductor companies face intense competition, both domestically and internationally, and such competition may have an adverse effect on profit margins. Semiconductor companies may have limited product lines, markets, financial resources or personnel. The products of semiconductor companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Capital equipment expenditures could be substantial, and equipment generally suffers from rapid obsolescence. Companies in the semiconductor industry are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights would adversely affect the profitability of these companies.

Stock Value Risk. Stocks involve the risk that they may never reach what the Adviser believes is their full market value, either because the market fails to recognize the stock’s intrinsic worth, or the Adviser misgauged that worth. Stocks also may decline in price, even though, in theory, they are already undervalued. Investments in private companies that lack readily observable or market-corroborated prices generally increase stock valuation risk because they are more difficult to value. Many private companies are not required to file periodic financial reports, leading to challenges in the Adviser’s ability to evaluate a company’s business prospects and the fair value of its securities. The fair valued prices assigned to the Fund’s investments in private companies are based on a variety of factors, reviewed regularly, and updated as additional information becomes available. However, fair value pricing includes subjective judgments, and it is possible that the fair value assigned to a security may differ materially from the value the Fund would realize if the security were sold.

Yieldcos Risk. Investments in securities of yieldcos involve risks that differ from investments in traditional operating companies, including risks related to the relationship between the yieldco and the company responsible for the formation of the yieldco (the “Yieldco Sponsor”). Yieldcos typically remain dependent on the management and administration services provided by or under the direction of the Yieldco Sponsor and on the ability of the Yieldco Sponsor to identify and present the yieldco with acquisition opportunities, which may often be assets of the Yieldco Sponsor itself. To the extent that the yieldco relies on the Yieldco Sponsor for developing new assets for potential future acquisitions, the yieldco may be dependent on the development capabilities and financial health of the Yieldco Sponsor. Yieldco Sponsors may have interests that conflict with the interests of the yieldco and may retain control of the yieldco via classes of stock held by the Yieldco Sponsor. Any event that limits the yieldco’s ability to maintain or grow its distributable cash flow would likely have a negative impact on the yieldco’s share price.

Performance: Because the Fund is a new fund and does not yet have a full calendar year of investment operations, no performance information is presented for the Fund at this time. In the future, performance information will be presented in this section of this Prospectus. Updated performance information will be available at no cost by calling 1-877-771-3836 and on the Fund’s website at www.EventideETFs.com.

Adviser: Eventide Asset Management, LLC is the Fund’s investment adviser.

Portfolio Managers: Andrew Singer, CFA, Portfolio Manager and Senior Research Analyst of the Adviser, and Dolores S. Bamford, CFA, Co-Chief Investment Officer and Senior Portfolio Manager of the Adviser, serve as Portfolio Managers of the Fund. Mr. Singer is the Lead Portfolio Manager of the Fund. Mr. Singer and Ms. Bamford have served the Fund in this capacity since the Fund launched in 2026.

Purchase and Sale of Fund Shares: You may purchase and sell individual Fund shares at market prices on the Exchange through your financial institution on each day that the Exchange is open for business (“Business Day”). Because individual Fund shares trade at market prices rather than at their NAV, Shares may trade at a price greater than NAV (premium) or less than NAV (discount). You may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares of the Fund (bid) and the lowest price a seller is willing to accept for Shares of the Fund (ask) when buying or selling Shares in the secondary market (the “bid-ask spread”).

Recent information, including information on the Fund’s NAV, market price, premiums and discounts, and bid-ask spreads, is available online at www.EventideETFs.com.

Tax Information: The Fund’s distributions from current and accumulated earnings and profits generally will be taxable as ordinary income or long-term capital gains. Distributions in excess of the Fund’s current and accumulated earnings and profits are treated as a tax-free return of capital to the extent of your basis in the Shares and as capital gain thereafter. A sale of Shares may result in capital gain or loss.

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 Adviser 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.
