**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, 2025, was 60% of the average value of its portfolio.

Principal Investment Strategies

Normally, the Gilead Fund invests primarily in a broad range of equity securities of any market capitalization. The Fund may invest without limitation in securities in companies domiciled outside the United States either directly or through American Depositary Receipts ("ADRs").

The Fund's investment adviser, Eventide Asset Management, LLC ("Eventide" or the "Adviser") analyzes the performance of potential investments not only for financial strength and outlook, but also for companies that are capable of 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." From time to time, 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, healthcare and life sciences sectors. The Fund may invest in private companies 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. The Fund may invest in development stage companies. 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:

**EVENTIDE**<sub>3</sub>

---

| | |
|:---|:---|
| **GILEAD FUND SUMMARY PROSPECTUS** | **November 1, 2025** |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Respecting the value and freedom of all people: this includes the right
to life at all stages and freedom from addictive behaviors caused by gambling, pornography, tobacco, and alcohol.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Demonstrating a concern for justice and peace: this includes fair and
ethical relationships with customers, suppliers, and business partners and avoiding products and services that promote weapons production
and proliferation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Promoting family and community: this includes protecting children from
violent forms of entertainment and serving low-income communities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Exhibiting responsible management practices: this includes fair dealing
with employees, communities, competitors, suppliers, and customers as demonstrated by a company's record regarding litigation, regulatory
actions against the company, and its record of providing products and services that improve the lives of people.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Practicing environmental stewardship: this includes practices considered
more sustainable than those of industry peers, reduction in environmental impact when compared to previous periods, and/or the use of
more efficient and cleaner energy sources.

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.

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 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.

**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.

**Development Stage Company Risk.** The Fund may invest a substantial portion of the portfolio in development stage companies that are not generating meaningful revenue.

**Equity Security Risk.** Common and 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. Warrants

| **GILEAD FUND SUMMARY PROSPECTUS** | **November 1, 2025** |

---

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.

**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.

**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 manager's 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 manager's judgments will produce the desired results.

**Market Risk.** Overall stock or bond market volatility 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 stocks 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.

**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.** 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. As the buyer of a put or call option, the Fund risks losing the entire premium invested in the option if the Fund does not exercise the option. As the seller (writer) of a put option, the Fund will lose money if the value of the security falls below the strike price. 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.

**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.

***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

| **GILEAD FUND SUMMARY PROSPECTUS** | **November 1, 2025** |

---

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.

**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.

**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.

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 N shares for each of the last ten full calendar years. Although Class A, C, and I shares have similar annual returns to Class N shares because the classes are invested in the same portfolio of securities, the returns for Class A, C, and I shares are different from Class N shares because Class A, C, and I shares have different expenses than Class N shares. The performance table shows how the average returns of Class A, C, I and N shares compare over time with those of a broad-based market index and a supplemental index (strategy benchmark) that the Adviser believes is more representative of the Fund's investment universe. 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.
