LETTER FROM THE CHAIRMAN

Dear Shareholders:

While economic growth remains subpar on a global basis, markets had largely recovered after a bout of volatility early this year only to be blindsided by the

unexpected vote by the United Kingdom to leave the European Union. Central bank policy remains accommodative globally, with the U.S. Federal Reserve recently signaling it will move slowly in tightening monetary policy as the labor market cools and inflation remains in check. This suggests a continuation of the “lower for longer” interest rate environment.

Overcapacity in the manufacturing sector has been restraining prices and profits around the world. China continues to grapple with challenges posed by its attempt to shift from an investment-led, export-driven model to a consumer-driven

economy, amplifying the global manufacturing glut. Emerging markets have been mixed of late, supported by firmer commodity prices but constrained by the prospect of tighter financial conditions in the wake of the Brexit vote.

At MFS®, we believe it is best to view markets through a long lens and not react to short-term swings. That makes it possible to filter out market noise and focus on long-term fundamentals.

In our view, the professional guidance of a financial advisor, along with a patient, long-term approach, will help you reach your investment objectives.

Respectfully,

Robert J. Manning

Chairman

MFS Investment Management

July 18, 2016

Portfolio Composition – continued

(a) For all securities other than those specifically described below, ratings are assigned to underlying securities utilizing ratings from Moody’s, Fitch, and Standard & Poor’s rating agencies and applying the following hierarchy: If all three agencies provide a rating, the middle rating (after dropping the highest and lowest ratings) is assigned; if two of the three agencies rate a security, the lower of the two is assigned. Ratings are shown in the S&P and Fitch scale (e.g., AAA). Securities rated BBB or higher are considered investment grade. All ratings are subject to change. Not Rated includes fixed income securities, including fixed income futures contracts, which have not been rated by any rating agency. The fund may not hold all of these instruments. The fund is not rated by these agencies.

(d) Duration is a measure of how much a bond’s price is likely to fluctuate with general changes in interest rates, e.g., if rates rise 1.00%, a bond with a 5-year duration is likely to lose about 5.00% of its value due to the interest rate move. This calculation is based on net assets applicable to common shares as of 5/31/16.

(i) For purposes of this presentation, the components include the value of securities, and reflect the impact of the equivalent exposure of derivative positions, if any. These amounts may be negative from time to time. Equivalent exposure is a calculated amount that translates the derivative position into a reasonable approximation of the amount of the underlying asset that the portfolio would have to hold at a given point in time to have the same price sensitivity that results from the portfolio’s ownership of the derivative contract. When dealing with derivatives, equivalent exposure is a more representative measure of the potential impact of a position on portfolio performance than value. The bond component will include any accrued interest amounts.

(j) For the purpose of managing the fund’s duration, the fund holds short treasury futures with a bond equivalent exposure of (19.0)%, which reduce the fund’s interest rate exposure but not its credit exposure.

(m) In determining an instrument’s effective maturity for purposes of calculating the fund’s dollar-weighted average effective maturity, MFS uses the instrument’s stated maturity or, if applicable, an earlier date on which MFS believes it is probable that a maturity-shortening device (such as a put, pre-refunding or prepayment) will cause the instrument to be repaid. Such an earlier date can be substantially shorter than the instrument’s stated maturity. This calculation is based on gross assets, which consists of net assets applicable to common shares plus the value of preferred shares, as of 5/31/16.

From time to time Cash & Cash Equivalents may be negative due to the aggregate liquidation value of preferred shares and/or timing of cash receipts.

Where the fund holds convertible bonds, these are treated as part of the equity portion of the portfolio.

Cash & Cash Equivalents includes any cash, investments in money market funds, short-term securities, and other assets less liabilities. Please see the Statement of Assets and Liabilities for additional information related to the fund’s cash position and other assets and liabilities.

Other includes currency derivatives and/or any offsets to derivative positions.

Percentages are based on net assets applicable to common shares as of 5/31/16.

The portfolio is actively managed and current holdings may be different.

PORTFOLIO MANAGERS’ PROFILES

Portfolio Manager	Primary Role	Since	Title and Five Year History
Gary Lasman	Portfolio Manager	2007	Investment Officer of MFS; employed in the investment management area of MFS since 2002.
Geoffrey Schechter	Portfolio Manager	2007	Investment Officer of MFS; employed in the investment management area of MFS since 1993.

OTHER NOTES

The fund’s shares may trade at a discount or premium to net asset value. When fund shares trade at a premium, buyers pay more than the net asset value underlying fund shares, and shares purchased at a premium would receive less than the amount paid for them in the event of the fund’s concurrent liquidation.

The fund’s monthly distributions may include a return of capital to shareholders to the extent that distributions are in excess of the fund’s net investment income and net capital gains, determined in accordance with federal income tax regulations. Distributions that are treated for federal income tax purposes as a return of capital will reduce each shareholder’s basis in his or her shares and, to the extent the return of capital exceeds such basis, will be treated as gain to the shareholder from a sale of shares. Returns of shareholder capital have the effect of reducing the fund’s assets and increasing the fund’s expense ratio.

In accordance with Section 23(c) of the Investment Company Act of 1940, the fund hereby gives notice that it may from time to time repurchase common and/or preferred shares of the fund in the open market at the option of the Board of Trustees and on such terms as the Trustees shall determine.

(a) Annualized.

(d) Per share data is based on average shares outstanding.

(f) Ratios do not reflect reductions from fees paid indirectly, if applicable.

(j) Total return at net asset value is calculated using the net asset value of the fund, not the publicly traded price and therefore may be different than the total return at market value.

(k) Calculated by subtracting the fund’s total liabilities (not including liquidation preference of ARPS and VMTPS) from the fund’s total assets and dividing this number by the total number of preferred shares outstanding.

(l) Interest expense and fees relate to payments made to the holders of the floating rate certificates from trust assets and interest expense paid to shareholders of VMTPS. For the year ended November 30, 2012, the expense ratio also excludes fees and expenses related to the tender and repurchase of a portion of the fund’s ARPS.

(m) Amount excludes accrued unpaid distributions on ARPS and accrued interest on VMTPS.

(n) Not annualized.

(p) Ratio excludes dividend payments on ARPS.

(r) Certain expenses have been reduced without which performance would have been lower.

(s) From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower.

(u) Average market value represents the approximate fair value of each of the fund’s ARPS and VMTPS.

(w) Per share amount was less than $0.01.

(x) The net asset values and total returns at net asset value have been calculated on net assets which include adjustments made in accordance with U.S. generally accepted accounting principles required at period end for financial reporting purposes.

(y) Included in the total return at net asset value for the year ended November 30, 2012 is the impact of the tender and repurchase by the fund of a portion of its ARPS at 95% of the ARPS’ per share liquidation preference. Had this transaction not occurred, the total return at net asset value for the year ended November 30, 2012 would have been lower by 2.52%.

NOTES TO FINANCIAL STATEMENTS

(unaudited)

(1) Business and Organization

MFS High Yield Municipal Trust (the fund) is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as a diversified closed-end management investment company.

The fund is an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services – Investment Companies.

(2) Significant Accounting Policies

General – The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. In the preparation of these financial statements, management has evaluated subsequent events occurring after the date of the fund’s Statement of Assets and Liabilities through the date that the financial statements were issued. The fund invests primarily in municipal instruments. The value of municipal instruments can be affected by changes in their actual or perceived credit quality. The credit quality of municipal instruments can be affected by, among other things, the financial condition of the issuer or guarantor, the issuer’s future borrowing plans and sources of revenue, the economic feasibility of the revenue bond project or general borrowing purpose, political or economic developments in the region where the instrument is issued and the liquidity of the security. Municipal instruments generally trade in the over-the-counter market. Municipal instruments backed by current and anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the taxation supporting the projects or assets or the inability to collect revenues for the project or from the assets. If the Internal Revenue Service determines an issuer of a municipal instrument has not complied with the applicable tax requirements, interest from the security could become taxable, the security could decline in value, and distributions made by the fund could be taxable to shareholders. The fund invests in high-yield securities rated below investment grade. Investments in high-yield securities involve greater degrees of credit and market risk than investments in higher-rated securities and tend to be more sensitive to economic conditions.

On March 24, 2016, the fund adopted the accounting provisions of FASB Accounting Standards Update 2015-03 (“ASU 2015-03”), Interest – Imputation of Interest (Topic 835-30) – Simplifying the Presentation of Debt Issuance Costs which resulted in a change in an accounting principle. Under ASU 2015-03, debt issuance costs are required to be presented as a direct deduction from the carrying amount of the related debt liability. Prior to the fund’s adoption of ASU 2015-03, debt issuance costs were deferred and presented as an asset.

In January 2016, FASB issued Accounting Standards Update 2016-01, Financial Instruments – Overall (Subtopic 825-10) – Recognition and Measurement of Financial

52

Notes to Financial Statements (unaudited) – continued

Assets and Financial Liabilities (“ASU 2016-01”) which would first be effective for annual reporting periods beginning after December 15, 2017, and interim periods therein. ASU 2016-01, which changes the accounting for equity investments and for certain financial liabilities, also modifies the presentation and disclosure requirements for financial instruments. Investment companies are specifically exempted from ASU 2016-01’s equity investment accounting provisions and will continue to follow the industry specific guidance for investment accounting under ASC 946. Although still evaluating the potential impacts of ASU 2016-01 to the fund, management expects that the impact of the fund’s adoption will be limited to additional financial statement disclosures.

Balance Sheet Offsetting – The fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the International Swaps and Derivatives Association (ISDA) Master Agreement does not result in an offset of reported amounts of financial assets and financial liabilities in the Statement of Assets and Liabilities across transactions between the fund and the applicable counterparty. The fund’s right to setoff may be restricted or prohibited by the bankruptcy or insolvency laws of the particular jurisdiction to which a specific master netting agreement counterparty is subject. Balance sheet offsetting disclosures, to the extent applicable to the fund, have been included in the fund’s Significant Accounting Policies note under the captions for each of the fund’s in-scope financial instruments and transactions.

Investment Valuations – Debt instruments and floating rate loans, including restricted debt instruments, are generally valued at an evaluated or composite bid as provided by a third-party pricing service. Short-term instruments with a maturity at issuance of 60 days or less may be valued at amortized cost, which approximates market value. Futures contracts are generally valued at last posted settlement price on their primary exchange as provided by a third-party pricing service. Futures contracts for which there were no trades that day for a particular position are generally valued at the closing bid quotation on their primary exchange as provided by a third-party pricing service. Open-end investment companies are generally valued at net asset value per share. Securities and other assets generally valued on the basis of information from a third-party pricing service may also be valued at a broker/dealer bid quotation. Values obtained from third-party pricing services can utilize both transaction data and market information such as yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data.

The Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of the fund’s investments (including any fair valuation) to the adviser pursuant to valuation policies and procedures approved by the Board. If the adviser determines that reliable market quotations are not readily available, investments are valued at fair value as determined in good faith by the adviser in accordance with such procedures under the oversight of the Board of Trustees. Under the fund’s valuation policies and procedures, market quotations are not considered to be readily available for most types of debt instruments and floating rate loans and many types of derivatives. These investments are generally valued at fair value based on information from third-party pricing services. In addition, investments may be valued at fair value if the adviser determines that an investment’s value has been materially affected by

53

Notes to Financial Statements (unaudited) – continued

events occurring after the close of the exchange or market on which the investment is principally traded (such as foreign exchange or market) and prior to the determination of the fund’s net asset value, or after the halting of trading of a specific security where trading does not resume prior to the close of the exchange or market on which the security is principally traded. The adviser generally relies on third-party pricing services or other information (such as the correlation with price movements of similar securities in the same or other markets; the type, cost and investment characteristics of the security; the business and financial condition of the issuer; and trading and other market data) to assist in determining whether to fair value and at what value to fair value an investment. The value of an investment for purposes of calculating the fund’s net asset value can differ depending on the source and method used to determine value. When fair valuation is used, the value of an investment used to determine the fund’s net asset value may differ from quoted or published prices for the same investment. There can be no assurance that the fund could obtain the fair value assigned to an investment if it were to sell the investment at the same time at which the fund determines its net asset value per share.

Various inputs are used in determining the value of the fund’s assets or liabilities. These inputs are categorized into three broad levels. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The fund’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment. Level 1 includes unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 includes other significant observable market-based inputs (including quoted prices for similar securities, interest rates, prepayment speed, and credit risk). Level 3 includes unobservable inputs, which may include the adviser’s own assumptions in determining the fair value of investments. Other financial instruments are derivative instruments not reflected in total investments, such as futures contracts. The following is a summary of the levels used as of May 31, 2016 in valuing the fund’s assets or liabilities:

Investments at Value	Level 1			Level 2		Level 3		Total
Municipal Bonds		$—			$211,994,780		$—		$211,994,780
Mutual Funds		1,102,537			—		—		1,102,537
Total Investments		$1,102,537			$211,994,780		$—		$213,097,317
Other Financial Instruments
Futures Contracts		$(76,011	)		$—		$—		$(76,011	)

For further information regarding security characteristics, see the Portfolio of Investments.

Derivatives – The fund uses derivatives for different purposes, primarily to increase or decrease exposure to a particular market or segment of the market, or security, to increase or decrease interest rate exposure, or as alternatives to direct investments. Derivatives are used for hedging or non-hedging purposes. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. When the fund uses derivatives as an investment to increase market exposure, or for hedging purposes, gains and losses from derivative instruments may be substantially greater than the derivative’s original cost.

54

Notes to Financial Statements (unaudited) – continued

The derivative instruments used by the fund were futures contracts. The fund’s period end derivatives, as presented in the Portfolio of Investments and the associated Derivative Contract tables, generally are indicative of the volume of its derivative activity during the period.

The following table presents, by major type of derivative contract, the fair value, on a gross basis, of the asset and liability components of derivatives held by the fund at May 31, 2016 as reported in the Statement of Assets and Liabilities:

		Fair Value (a)
Risk	Derivative Contracts		Liability Derivatives
Interest Rate	Interest Rate Futures			$(76,011)

(a) The value of futures contracts includes cumulative appreciation (depreciation) as reported in the fund’s Portfolio of Investments. Only the current day net variation margin for futures contracts is separately reported within the fund’s Statement of Assets and Liabilities.

The following table presents, by major type of derivative contract, the realized gain (loss) on derivatives held by the fund for the six months ended May 31, 2016 as reported in the Statement of Operations:

Risk	Futures Contracts
Interest Rate		$(814,927	)

The following table presents, by major type of derivative contract, the change in unrealized appreciation (depreciation) on derivatives held by the fund for the six months ended May 31, 2016 as reported in the Statement of Operations:

Risk	Futures Contracts
Interest Rate		$(66,383	)

Derivative counterparty credit risk is managed through formal evaluation of the creditworthiness of all potential counterparties. On certain, but not all, uncleared derivatives, the fund attempts to reduce its exposure to counterparty credit risk whenever possible by entering into an ISDA Master Agreement on a bilateral basis. The ISDA Master Agreement gives each party to the agreement the right to terminate all transactions traded under such agreement if there is a certain deterioration in the credit quality of the other party. Upon an event of default or a termination of the ISDA Master Agreement, the non-defaulting party has the right to close out all transactions traded under such agreement and to net amounts owed under each transaction to one net amount payable by one party to the other. This right to close out and net payments across all transactions traded under the ISDA Master Agreement could result in a reduction of the fund’s credit risk to such counterparty equal to any amounts payable by the fund under the applicable transactions, if any.

Collateral and margin requirements differ by type of derivative. Margin requirements are set by the clearing broker and the clearing house for cleared derivatives (e.g., futures contracts, cleared swaps, and exchange-traded options) while collateral terms are contract specific for uncleared derivatives (e.g., forward foreign currency exchange contracts, uncleared swap agreements, and uncleared options). For derivatives traded under an ISDA Master Agreement, which contains a collateral support annex, the collateral requirements are netted across all transactions traded under such agreement

55

Notes to Financial Statements (unaudited) – continued

and one amount is posted from one party to the other to collateralize such obligations. Cash that has been segregated to cover the fund’s collateral or margin obligations under derivative contracts, if any, will be reported separately in the Statement of Assets and Liabilities as “Restricted cash” or “Deposits with brokers.” Securities pledged as collateral or margin for the same purpose, if any, are noted in the Portfolio of Investments.

Futures Contracts – The fund entered into futures contracts which may be used to hedge against or obtain broad market exposure, interest rate exposure, or to manage duration. A futures contract represents a commitment for the future purchase or sale of an asset at a specified price on a specified date.

Upon entering into a futures contract, the fund is required to deposit with the broker, either in cash or securities, an initial margin in an amount equal to a certain percentage of the notional amount of the contract. Subsequent payments (variation margin) are made or received by the fund each day, depending on the daily fluctuations in the value of the contract, and are recorded for financial statement purposes as unrealized gain or loss by the fund until the contract is closed or expires at which point the gain or loss on futures contracts is realized.

The fund bears the risk of interest rates or securities prices moving unexpectedly, in which case, the fund may not achieve the anticipated benefits of the futures contracts and may realize a loss. While futures contracts may present less counterparty risk to the fund since the contracts are exchange traded and the exchange’s clearinghouse guarantees payments to the broker, there is still counterparty credit risk due to the insolvency of the broker. The fund’s maximum risk of loss due to counterparty credit risk is equal to the margin posted by the fund to the broker plus any gains or minus any losses on the outstanding futures contracts.

Statement of Cash Flows – Information on financial transactions which have been settled through the receipt or disbursement of cash is presented in the Statement of Cash Flows. The cash amount shown in the Statement of Cash Flows is the amount included within the fund’s Statement of Assets and Liabilities and includes cash on hand at its custodian bank and does not include any short-term investments.

Indemnifications – Under the fund’s organizational documents, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the fund. Additionally, in the normal course of business, the fund enters into agreements with service providers that may contain indemnification clauses. The fund’s maximum exposure under these agreements is unknown as this would involve future claims that may be made against the fund that have not yet occurred.

Investment Transactions and Income – Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. Interest payments received in additional securities are recorded on the ex-interest date in an amount equal to the value of the security on such date. Debt obligations may be placed on non-accrual status or set to accrue at a rate of interest less than the contractual coupon when the collection of all or a portion of interest has become doubtful. Interest income for those debt obligations may be further reduced by the write-off of the related interest receivables when deemed uncollectible.

56

Notes to Financial Statements (unaudited) – continued

The fund may receive proceeds from litigation settlements. Any proceeds received from litigation involving portfolio holdings are reflected in the Statement of Operations in realized gain/loss if the security has been disposed of by the fund or in unrealized gain/loss if the security is still held by the fund. Any other proceeds from litigation not related to portfolio holdings are reflected as other income in the Statement of Operations.

Legal fees and other related expenses incurred to preserve and protect the value of a security owned are added to the cost of the security; other legal fees are expensed. Capital infusions made directly to the security issuer, which are generally non-recurring, incurred to protect or enhance the value of high-yield debt securities, are reported as additions to the cost basis of the security. Costs that are incurred to negotiate the terms or conditions of capital infusions or that are expected to result in a plan of reorganization are reported as realized losses. Ongoing costs incurred to protect or enhance an investment, or costs incurred to pursue other claims or legal actions, are expensed.

Fees Paid Indirectly – Prior to October 1, 2015, the fund’s custody fee could be reduced by a credit earned under an arrangement that measured the value of U.S. dollars deposited with the custodian by the fund. For the six months ended May 31, 2016, custody fees were not reduced.

Tax Matters and Distributions – The fund intends to qualify as a regulated investment company, as defined under Subchapter M of the Internal Revenue Code, and to distribute all of its taxable and tax-exempt income, including realized capital gains. As a result, no provision for federal income tax is required. The fund’s federal tax returns, when filed, will remain subject to examination by the Internal Revenue Service for a three year period. Management has analyzed the fund’s tax positions taken on federal and state tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

Distributions to shareholders are recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. generally accepted accounting principles. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These adjustments have no impact on net assets or net asset value per share. Temporary differences which arise from recognizing certain items of income, expense, gain or loss in different periods for financial statement and tax purposes will reverse at some time in the future. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes.

Book/tax differences primarily relate to defaulted bonds, expiration of capital loss carryforwards, amortization and accretion of debt securities, and non-deductible expenses that result from the treatment of VMTPS as equity for tax purposes.

57

Notes to Financial Statements (unaudited) – continued

The tax character of distributions made during the current period will be determined at fiscal year end. The tax character of distributions declared to shareholders for the last fiscal year is as follows:

	11/30/15
Ordinary income (including any short-term capital gains)		$16,424
Tax-exempt income		8,856,265
Total distributions		$8,872,689

The federal tax cost and the tax basis components of distributable earnings were as follows:

As of 5/31/16
Cost of investments	$192,045,524
Gross appreciation	22,392,345
Gross depreciation	(1,340,552	)
Net unrealized appreciation (depreciation)	$21,051,793
As of 11/30/15
Undistributed ordinary income	105,280
Undistributed tax-exempt income	1,257,013
Capital loss carryforwards	(35,197,861	)
Other temporary differences	(582,280	)
Net unrealized appreciation (depreciation)	17,005,112

The aggregate cost above includes prior fiscal year end tax adjustments, if applicable.

Under the Regulated Investment Company Modernization Act of 2010 (the “Act”), net capital losses recognized for fund fiscal years beginning after November 30, 2011 may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses (“post-enactment losses”). Previously, net capital losses were carried forward for eight years and treated as short-term losses (“pre-enactment losses”). As a transition rule, the Act requires that all post-enactment net capital losses be used before pre-enactment net capital losses.

As of November 30, 2015, the fund had capital loss carryforwards available to offset future realized gains as follows:

Pre-enactment losses which expire as follows:
11/30/16	$(11,728,477	)
11/30/17	(10,848,523	)
11/30/18	(3,454,980	)
11/30/19	(4,608,836	)
Total	$(30,640,816	)
Post-enactment losses which are characterized as follows:
Short-Term	$(1,509,175	)
Long-Term	(3,047,870	)
Total	$(4,557,045	)

(3) Transactions with Affiliates

Investment Adviser – The fund has an investment advisory agreement with MFS to provide overall investment management and related administrative services and facilities to the fund. The management fee is computed daily and paid monthly at an annual rate of 0.65% of the fund’s average daily net assets (including the value of preferred shares).

The investment adviser has agreed in writing to pay a portion of the fund’s total annual operating expenses, excluding interest, taxes, extraordinary expenses, brokerage and transaction costs, and investment-related expenses, such that total fund operating expenses do not exceed 0.87% annually of the fund’s average daily net assets (including the value of preferred shares). This written agreement will continue until modified by the fund’s Board of Trustees, but such agreement will continue at least until November 30, 2017. For the six months ended May 31, 2016, the fund’s actual operating expenses did not exceed the limit and therefore, the investment adviser did not pay any portion of the fund’s expenses related to this agreement.

Transfer Agent – The fund engages Computershare Trust Company, N.A. (“Computershare”) as the sole transfer agent for the fund’s common shares. MFS Service Center, Inc. (MFSC) monitors and supervises the activities of Computershare for an agreed upon fee approved by the Board of Trustees. For the six months ended May 31, 2016, these fees paid to MFSC amounted to $4,622.

Administrator – MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to the fund. Under an administrative services agreement, the fund reimburses MFS the costs incurred to provide these services. The fund is charged an annual fixed amount of $17,500 plus a fee based on average daily net assets (including the value of preferred shares). The administrative services fee incurred for the six months ended May 31, 2016 was equivalent to an annual effective rate of 0.0202% of the fund’s average daily net assets (including the value of preferred shares).

Trustees’ and Officers’ Compensation – The fund pays compensation to independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. The fund does not pay compensation directly to Trustees or officers of the fund who are also officers of the investment adviser, all of whom receive remuneration for their services to the fund from MFS. Certain officers and Trustees of the fund are officers or directors of MFS and MFSC.

Other – This fund and certain other funds managed by MFS (the funds) have entered into a service agreement (the ISO Agreement) which provides for payment of fees solely by the funds to Tarantino LLC in return for the provision of services of an Independent Senior Officer (ISO) for the funds. Frank L. Tarantino serves as the ISO and is an officer of the funds and the sole member of Tarantino LLC. The funds can terminate the ISO Agreement with Tarantino LLC at any time under the terms of the ISO Agreement. For the six months ended May 31, 2016, the fee paid by the fund under this agreement was $154 and is included in “Miscellaneous” expense in the Statement of Operations. MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ISO.

59

Notes to Financial Statements (unaudited) – continued

The fund invests in the MFS Institutional Money Market Portfolio which is managed by MFS and seeks current income consistent with preservation of capital and liquidity. Income earned on this investment is included in “Dividends from underlying affiliated funds” in the Statement of Operations. This money market fund does not pay a management fee to MFS.

(4) Portfolio Securities

For the six months ended May 31, 2016, purchases and sales of investments, other than short-term obligations, aggregated $17,765,725 and $17,267,613, respectively.

(5) Shares of Beneficial Interest

The fund’s Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. The fund reserves the right to repurchase shares of beneficial interest of the fund subject to Trustee approval. During the six months ended May 31, 2016 and the year ended November 30, 2015, the fund did not repurchase any shares. Other transactions in fund shares were as follows:

	Six months ended 5/31/16				Year ended 11/30/15
	Shares		Amount		Shares		Amount
Shares issued to shareholders in reinvestment of distributions		5,334		$26,084		—		$—

(6) Line of Credit

The fund and certain other funds managed by MFS participate in a $1.25 billion unsecured committed line of credit, subject to a $1 billion sublimit, provided by a syndication of banks under a credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, generally at a rate equal to the higher of the Overnight Federal Reserve funds rate or daily one month LIBOR plus an agreed upon spread. A commitment fee, based on the average daily, unused portion of the committed line of credit, is allocated among the participating funds at the end of each calendar quarter. In addition, the fund and other funds managed by MFS have established unsecured uncommitted borrowing arrangements with certain banks for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Overnight Federal Reserve funds rate plus an agreed upon spread. For the six months ended May 31, 2016, the fund’s commitment fee and interest expense were $303 and $0, respectively, and are included in “Miscellaneous” expense in the Statement of Operations.

(7) Transactions in Underlying Affiliated Funds-Affiliated Issuers

An affiliated issuer may be considered one in which the fund owns 5% or more of the outstanding voting securities, or a company which is under common control. For the purposes of this report, the fund assumes the following to be an affiliated issuer:

Underlying Affiliated Fund	Beginning Shares/Par Amount		Acquisitions Shares/Par Amount		Dispositions Shares/Par Amount			Ending Shares/Par Amount

MFS Institutional Money Market Portfolio		$—		$—		$2,899			$1,102,537

(8) Preferred Shares

As of March 23, 2016, the fund had 2,844 shares issued and outstanding of Variable Rate Municipal Term Preferred Shares, series 2016/9 (Series 2016 VMTPS) and 156 shares issued and outstanding of Auction Rate Preferred Shares (ARPS), series F, each with a liquidation preference of $25,000 per share. Subsequent to March 23, 2016, all shares of the Series 2016 VMTPS and the ARPS were redeemed using proceeds from the issuance of a new series of Variable Rate Municipal Term Preferred Shares as further described below.

The Series 2016 VMTPS were a variable rate form of preferred shares with a term redemption date of September 30, 2016 unless extended through negotiation with the private holders of the Series 2016 VMTPS. Dividends were set weekly to a fixed spread against the Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Index. During the period December 1, 2015 through March 23, 2016, the Series 2016 VMTPS dividend rates ranged from 1.26% to 1.38%. For the period December 1, 2015 through March 23, 2016, the average dividend rate was 1.27%. Dividends paid to the Series 2016 VMTPS were treated as interest expense and recorded as incurred. For the period December 1, 2015 through March 23, 2016, interest expense related to the Series 2016 VMTPS amounted to $289,121 and is included in “Interest expense” in the Statement of Operations.

The ARPS were preferred shares whose dividends were reset every seven days through an auction process. During the time the ARPS were outstanding, if the ARPS were unable to be remarketed on a remarketing date as part of the auction process, the fund was required to pay the maximum applicable rate on the ARPS to holders of such shares for successive dividend periods until such time as the shares were successfully remarketed. The maximum rate on the ARPS rated aa3/AA- or better was equal to 110% of the higher of (i) the Taxable Equivalent of the Short-Term Municipal Bond Rate or (ii) the “AA” Composite Commercial Paper Rate. Since February 2008, regularly scheduled auctions for the ARPS have failed. During the six months ended May 31, 2016, the ARPS dividend rates ranged from 0.19% to 0.59% for series F. For the six months ended May 31, 2016, the average ARPS dividend rate was 0.43% for series F.

The fund paid an annual service fee to broker-dealers with customers who were beneficial owners of the ARPS. The service fee was equivalent to 0.25% of the applicable ARPS liquidation value while the ARPS auctions were successful or to 0.15% or less, varying by broker-dealer, while the auctions were failing.

On March 24, 2016, the fund issued 3,000 shares of a new series of Variable Rate Municipal Term Preferred Shares (“Series 2019 VMTPS”) in a private offering with an aggregate liquidation preference of $75,000,000. The fund used a portion of the proceeds from the sale of its Series 2019 VMTPS to fund the redemption on March 24, 2016 of all of its outstanding Series 2016 VMTPS and used the remaining portion of its Series 2019 VMTPS offering proceeds to fund the redemption of all of its outstanding ARPS. The redemption date for the fund’s series F ARPS was April 28, 2016. The ARPS were redeemed at their respective liquidation preferences of $25,000 per share plus dividends owed through, but excluding, the applicable redemption dates. Taking into account its Series 2019 VMTPS issuance and the redemption of the outstanding Series 2016 VMTPS and the ARPS, the amount of the fund’s assets attributable to preferred shares and related leverage remains unchanged.

The Series 2019 VMTPS are redeemable at the option of the fund in whole or in part at the liquidation preference of $25,000 per share, plus accumulated and unpaid dividends, but generally solely for the purpose of decreasing the leverage of the fund. The Series 2019 VMTPS are subject to a mandatory term redemption date of March 31, 2019 unless extended through negotiation with the private holders of the Series 2019 VMTPS. There is no assurance that the term of the Series 2019 VMTPS will be extended or that the Series 2019 VMTPS will be replaced with any other preferred shares or other form of leverage upon the redemption of the Series 2019 VMTPS. Six months prior to the term redemption date of the Series 2019 VMTPS, the fund is required to begin to segregate liquid assets with the fund’s custodian to fund the redemption. Dividends on the Series 2019 VMTPS are cumulative and are set weekly to a fixed spread against the SIFMA Municipal Swap Index. During the period from issuance on March 24, 2016 through May 31, 2016, the Series 2019 VMTPS dividend rates ranged from 1.44% to 1.56%. For the period March 24, 2016 through May 31, 2016, the average dividend rate was 1.54%.

In the fund’s Statement of Assets and Liabilities, the Series 2019 VMTPS aggregate liquidation preference is shown as a liability since they have a stated mandatory redemption date. Dividends paid to the Series 2019 VMTPS are treated as interest expense and recorded as incurred. For the period March 24, 2016 through May 31, 2016, interest expense related to the Series 2019 VMTPS amounted to $217,439 and is included in “Interest expense” in the Statement of Operations. Costs directly related to the issuance of the Series 2019 VMTPS are considered debt issuance costs. Debt issuance costs are presented as a direct deduction from the carrying amount of the related debt liability and are being amortized into interest expense over the life of the Series 2019 VMTPS. The period-end carrying value for the Series 2019 VMTPS in the fund’s Statement of Assets and Liabilities is its liquidation value less any unamortized debt issuance costs, which approximates its fair value. Its fair value would be considered level 2 under the fair value hierarchy.

Notes to Financial Statements (unaudited) – continued

Under the terms of a purchase agreement between the fund and the investor in the Series 2019 VMTPS, the fund is subject to various investment restrictions that are substantially similar to those that were in place with respect to the Series 2016 VMTPS. These investment-related requirements are in various respects more restrictive than those to which the fund is otherwise subject in accordance with its investment objectives and policies. In addition, the fund is subject to certain restrictions on its investments imposed by guidelines of the rating agencies that rate the Series 2019 VMTPS, which guidelines may be changed by the applicable rating agency, in its sole discretion, from time to time. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the fund by the Investment Company Act of 1940 (the “1940 Act”).

The fund is required to maintain certain asset coverage with respect to the Series 2019 VMTPS as defined in the fund’s governing documents and the 1940 Act. One of a number of asset coverage-related requirements is that the fund is not permitted to declare or pay common share dividends unless immediately thereafter the fund has a minimum asset coverage ratio of 200% with respect to the Series 2019 VMTPS after deducting the amount of such common share dividends.

The 1940 Act requires that the preferred shareholders of the fund, voting as a separate class, have the right to elect at least two trustees at all times, and elect a majority of the trustees at any time when dividends on the preferred shares are unpaid for two full years. Unless otherwise required by law or under the terms of the preferred shares, each preferred shareholder is entitled to one vote and preferred shareholders will vote together with common shareholders as a single class.

Leverage involves risks and special considerations for the fund’s common shareholders. To the extent that investments are purchased by the fund with proceeds from the issuance of preferred shares, the fund’s net asset value will increase or decrease at a greater rate than a comparable unleveraged fund. Changes in the value of the fund’s portfolio will be borne entirely by the common shareholders. It is possible that the fund will be required to sell assets at a time when it may be disadvantageous to do so in order to redeem preferred shares to comply with asset coverage or other restrictions including those imposed by the 1940 Act and the rating agencies that rate the preferred shares. There is no assurance that the fund’s leveraging strategy will be successful.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and Shareholders of MFS High Yield Municipal Trust:

We have reviewed the accompanying statement of assets and liabilities of MFS High Yield Municipal Trust (the Fund), including the portfolio of investments, as of May 31, 2016, and the related statements of operations, changes in net assets, cash flows and financial highlights for the six-month period ended May 31, 2016. These interim financial statements and financial highlights are the responsibility of the Fund’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying interim financial statements and financial highlights for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the statement of changes in net assets for the year ended November 30, 2015 and the financial highlights for each of the five years in the period ended November 30, 2015, and in our report dated January 15, 2016, we expressed an unqualified opinion on such statement of changes in net assets and financial highlights.
