This information supplements certain information contained in the Statement of Additional Information ("SAI") for the Fund, dated June 8, 2022, and should be read in conjunction with such SAI.

The section of the Fund's SAI entitled "Reduction of Up-Front Sales Charge on Class A Shares - Rights of Accumulation" is deleted and replaced with the following

Rights of Accumulation

A right of accumulation ("ROA") permits an investor to aggregate shares (of any class) owned by the investor, his spouse, children and grandchildren under 21 (cumulatively, the "Investor") in some or all of the Funds in the Eventide family of funds to reach a breakpoint discount. This includes accounts held with other financial institutions and accounts established for a single trust estate or single fiduciary account, including a qualified retirement plan such as an IRA, 401(k) or 403(b) plan (some restrictions may apply). The value of shares eligible for a cumulative quantity discount equals the cumulative cost of the shares purchased (not including reinvested dividends) or the current account market value; whichever is greater. The current market value of the shares is determined by multiplying the number of shares by the previous day's NAV.

For example, if an investor owned Class C shares of the Eventide Gilead Fund worth $40,000 at the current NAV and purchased an additional $10,000 of Class A shares of the Fund, the sales charge for the $10,000 purchase would be at the rate applicable to a single $50,000 purchase.

To qualify for a ROA on a purchase of Class A shares through a broker-dealer, when each purchase is made, the individual investor or the broker-dealer must provide the respective Fund with sufficient information to verify that the purchase qualifies for the discount.
