By:/s/ Phillip Goldstein By:/s/ Andrew Dakos Phillip Goldstein Andrew Dakos BULLDOG INVESTORS, LLP By:/s/ Andrew Dakos Andrew Dakos, Partner Exhibit B: Special Opportunities Fund, Inc. 615 East Michigan Street, Milwaukee, WI 53202 July 10, 2023 Heidi W. Hardin, Secretary MFS High Yield Municipal Trust 111 Huntington Avenue Boston, Massachusetts 02199 Dear Ms. Hardin: Special Opportunities Fund (the Fund) beneficially owns and is entitled to vote 617,138 shares of MFS High Yield Municipal Trust (the Trust). Please be advised that the Fund intends to arrange for a representative to attend the 2023 Annual Meeting of Shareholders in person or by proxy and to nominate the following persons for election as Trustees of the Trust and present the proposal set forth below. Paul Poole, 57, DOB:May 5, 1966, 17 Quaker Lane, Chappaqua, NY 10514 Jake Pampinella, 21, DOB: August 24, 2001, 267 84 Street, Brooklyn, NY 11209 The business and residential addresses of the nominees are the same and each is a U.S. citizen. Except as set forth in the balance of this paragraph, the information requested in Section (2.2)(c) of the Trust's By-Laws is inapplicable as to either nominee. Neither nominee owns shares of the Trust or is or will be an interested person of the Trust. There are no arrangements or understandings between the Fund or any other person pursuant to which the nomination of either proposed nominee will be presented. Should they be elected as Trustees, there are no arrangements with anyone regarding their duties to the Trust. To our knowledge, there is no additional information about either nominee (or the Fund) that is, or will be, required by any SEC rule or regulation in connection with any proxy statement or other filing made in connection with solicitation of proxies for election of Trustees or directors pursuant to Section 14 of the Securities Exchange Act of 1934 and the rules and regulations promulgated thereunder.1 The Fund also intends to submit the following non-binding proposal at the Annual Meeting for a vote of the shareholders: "The board shall consider authorizing a liquidity event that will allow shareholders to monetize a significant percentage of their shares at or close to net asset value." With the Trust's current discount at about 14%, the purpose of this proposal is self-evident. Please advise us if you or a representative of the Board would like to discuss any of the above matters or would like any additional information about our nominees or proposal. Very truly yours, /S/ Phillip Goldstein Phillip Goldstein Chairman Footnote: 1 In addition, it is premature to demand the information set forth in subsection (i)(C) and (D) because such information cannot be accurately determined until a proxy statement is actually prepared. Moreover, we question whether there is a legitimate business purpose for requiring such information to be provided to anyone other than shareholders of the Trust. However, we will endeavor to ensure that all proxy materials disseminated to shareholders in connection with our nominations and proposal complies with Section 14 of the Securities Exchange Act of 1934 and the rules and regulations promulgated thereunder.
