(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. If none of the 3 rating agencies above assign a rating, but the security is rated by DBRS Morningstar, then the DBRS Morningstar rating is assigned. If none of the 4 rating agencies listed above rate the security, but the security is rated by the Kroll Bond Rating Agency (KBRA), then the KBRA rating 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 and fixed income derivatives that have not been rated by any rating agency. The fund may or may not have held all of these instruments on this date. 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. The Average Duration calculation reflects the impact of the equivalent exposure of derivative positions, if any. 
(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.
(m) In determining each 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 feature (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.
Cash & Cash Equivalents includes any cash, investments in money market funds, short-term securities, and other assets less liabilities. Please see the Statements of Assets and Liabilities for additional information related to the fund’s cash position and other assets and liabilities.
Percentages are based on net assets as of March 31, 2024.

Management Review 
Summary of Results
For the twelve months ended March 31, 2024, the total return for the Class A shares, at net asset value, of the municipal bond funds of Alabama, California, Georgia, Maryland, and Massachusetts outperformed the return of the Bloomberg Municipal Bond Index, while the municipal bond fund of Arkansas underperformed the same benchmark. The performance of the individual funds and the benchmark are set forth in the Performance Summary.
Market Environment
In response to the strongest inflationary episode in four decades, global central banks tightened monetary policy significantly during the reporting period, helping reduce price pressures, although more work remains to be done before inflation returns to target. Geopolitical strains remained high amid ongoing conflicts in Ukraine and in the Middle East, while relations between China and the US remained tense as the US sought to restrict the flow of advanced technologies to China and China looked to use its industrial overcapacity to increase exports to developed markets to bolster its slow-growing domestic economy. The conflict in the Middle East has resulted in trade flow disruptions between Asia and Europe as shipping traffic was routed away from the Red Sea.
Although inflation has yet to reach central banks’ targets, policymakers have telegraphed their intentions to begin cutting rates in the months ahead. The prospects for easier monetary policy along with resilient global economic growth have been supportive factors for risky assets, such as equities and high-yield bonds. Long-term interest rates moderated during the latter half of the period, although rising government debt levels remained a concern over the medium term. Advancements in artificial intelligence and the adoption of novel weight-loss drugs were two areas of focus for investors during the period.
Amid this eventful backdrop, the investment grade municipal market generated positive returns over the period. Securities in the lower-rated investment grade credit quality tiers and longer duration assets outperformed. Yields rose across the tax-exempt municipal curve, most notably in the short (within two years) segment. A positive for income-oriented investors, the yield (yield-to-worst) on the investment grade municipal index ended the period at 3.49%, well above its 5 and 10-year average.
Factors Affecting Performance
Across all funds, exposure to the state sector contributed to performance relative to the Bloomberg Municipal Bond Index. From a quality perspective, the fund’s exposure to non-rated(r) securities, which are not held in the benchmark, strengthened relative results. Favorable bond selection within “AA” rated debt issuers, across all funds except the municipal bond fund of Maryland, also benefited relative returns.
Conversely, exposure to the power sector, most notably within “D” and “CC” rated securities, for which the benchmark has no exposure, weakened relative performance across all funds. Within the Arkansas municipal bond fund, a higher exposure to poor performing power sector bonds was the primary driver of negative relative results.
Respectfully,
Portfolio Manager(s)
Michael Dawson
(r) Securities rated “BBB”, “Baa”, or higher are considered investment grade; securities rated “BB”, “Ba”, or below are considered non-investment grade. Ratings are assigned to underlying securities utilizing ratings from Moody's, Fitch, and Standard & Poor's 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. If none of the 3 rating agencies above assign a rating, but the security is rated by DBRS Morningstar, then the DBRS Morningstar rating is assigned. If none of the 4 rating agencies listed above rate the security, but the security is rated by the Kroll Bond Rating Agency (KBRA), then the KBRA rating is assigned. Ratings are shown in the S&P and Fitch scale (e.g., AAA). For securities that are not rated by any of the rating agencies, the security is considered Not Rated.

Performance Summary THROUGH 3/31/24
The following charts illustrate a representative class of each fund’s historical performance in comparison to its benchmark(s). Performance results include the deduction of the maximum applicable sales charge and reflect the percentage change in net asset value, including reinvestment of dividends and capital gains distributions. The performance of other share classes will be greater than or less than that of the class depicted below. Each fund's results have been compared to the Bloomberg Municipal Bond Index, a market capitalization-weighted index that measures the performance of the tax-exempt bond market. However, while this index is considered the benchmark for the performance of municipal bond funds, it is comprised of municipal bonds issued within the 50 states and the District of Columbia as well as U.S. territories and possessions such as Guam, Puerto Rico, and the Virgin Islands, while each of the funds invests a large percentage of its assets in municipal issuers of the state that is in the fund’s name. Benchmarks are unmanaged and may not be invested in directly. Benchmark returns do not reflect sales charges, commissions or expenses. (See Notes to Performance Summary.)
Performance data shown represents past performance and is no guarantee of future results. Investment return and principal value fluctuate so your shares, when sold, may be worth more or less than the original cost; current performance may be lower or higher than quoted. The performance shown does not reflect the deduction of taxes, if any, that a shareholder would pay on fund distributions or the redemption of fund shares.

Notes to Performance Summary
Average annual total return represents the average annual change in value for each share class for the periods presented. Life returns are presented where the share class has less than 10 years of performance history and represent the average annual total return from the class inception date to the stated period end date. As the fund's share classes may have different inception dates, the life returns may represent different time periods and may not be comparable. As a result, no comparative benchmark performance information is provided for life periods.

Performance Summary  - continued
Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers each fund's performance results would be less favorable. Please see the prospectus and financial statements for complete details.
Performance results do not include adjustments made for financial reporting purposes in accordance with U.S. generally accepted accounting principles and may differ from amounts reported in the financial highlights.  
A portion of the fund’s monthly distributions may be subject to state, federal, and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax.
From time to time the funds may receive proceeds from litigation settlements, without which performance would be lower.

Expense Tables 
Fund expenses borne by the shareholders during the period, October 1, 2023 through March 31, 2024
As a shareholder of the funds, you incur two types of costs: (1) transaction costs, including sales charges (loads) on certain purchase or redemption payments, and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other fund expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in the funds and to compare these costs with the ongoing costs of investing in other mutual funds.
These examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire period October 1, 2023 through March 31, 2024.
Actual Expenses
The first line for each share class in the following tables provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.
Hypothetical Example for Comparison Purposes
The second line for each share class in the following tables provides information about hypothetical account values and hypothetical expenses based on each fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not each fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in each fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.
Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second line for each share class in the tables is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Notes to Financial Statements 
(1)  Business and Organization
MFS Alabama Municipal Bond Fund (Alabama Fund), MFS Arkansas Municipal Bond Fund (Arkansas Fund), MFS California Municipal Bond Fund (California Fund), MFS Georgia Municipal Bond Fund (Georgia Fund), MFS Maryland Municipal Bond Fund (Maryland Fund), and MFS Massachusetts Municipal Bond Fund (Massachusetts Fund) are each a diversified series of MFS Municipal Series Trust which is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company.
Each 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 each fund’s Statement of Assets and Liabilities through the date that the financial statements were issued. Each fund invests primarily in municipal instruments, which generally trade in the over-the-counter market. The value of municipal instruments can be affected by changes in their actual or perceived credit quality. The credit quality of, and the ability to pay principal and interest when due by, an issuer of a municipal instrument depends on the credit quality of the entity supporting the municipal instrument, how essential any services supported by the municipal instrument are, the sufficiency of any revenues or taxes that support the municipal instrument, and/or the willingness or ability of the appropriate government entity to approve any appropriations necessary to support the municipal instrument. Municipal instruments may be supported by insurance which typically guarantees the timely payment of all principal and interest due on the underlying municipal instrument. The value of a municipal instrument can be volatile and significantly affected by adverse tax changes or court rulings, legislative or political changes, changes in specific or general market and economic conditions in the region or state where the instrument is issued, and the financial condition of municipal issuers and of municipal instrument insurers of which there are a limited number. Also, because many municipal instruments are issued to finance similar projects, conditions in certain industries can significantly affect the funds and the overall municipal market. 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 funds could be taxable to shareholders.
Balance Sheet Offsetting — Each 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, or similar agreement, does not result in an offset of reported amounts of financial assets and financial liabilities in the Statements of Assets and Liabilities across transactions between each fund and the applicable counterparty. Each 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 each fund, have been included in each fund’s Significant Accounting Policies note under the captions for each of the fund’s in-scope financial instruments and transactions.
Investment Valuations Subject to its oversight, the funds' Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of each fund’s investments to MFS as the funds' adviser, pursuant to each fund’s valuation policy and procedures which have been adopted by the adviser and approved by the Board. In accordance with Rule 2a-5 under the Investment Company Act of 1940, the Board of Trustees designated the adviser as the “valuation designee” of each fund. If the adviser, as valuation designee, determines that reliable market quotations are not readily available for an investment, the investment is valued at fair value as determined in good faith by the adviser in accordance with the adviser’s fair valuation policy and procedures.
Under each fund's valuation policy and procedures, 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. Open-end investment companies are generally valued at net asset value per share.
Under each fund’s valuation policy and procedures, market quotations are not considered to be readily available for debt instruments, floating rate loans, and many types of derivatives. These investments are generally valued at fair value based on information from third-party pricing services or otherwise determined by the adviser in accordance with the adviser’s fair valuation policy and procedures. 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. In determining values, third-party pricing services can utilize both transaction data and market information such as yield, quality, coupon rate, maturity, type of issue, trading characteristics, spreads and other market data. An investment may also be valued at fair value if the adviser determines that the investment’s value has been materially affected by 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 each fund’s net asset value, or after the halt 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

Notes to Financial Statements  - continued
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 each 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 each fund’s net asset value may differ from quoted or published prices for the same investment. There can be no assurance that each fund could obtain the fair value assigned to an investment if it were to sell the investment at the same time at which each fund determines its net asset value per share.
Various inputs are used in determining the value of each 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. Each 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 significant unobservable inputs, which may include the adviser's own assumptions in determining the fair value of investments. The following is a summary of the levels used as of March 31, 2024 in valuing each fund's assets and liabilities:

For further information regarding security characteristics, see the Portfolio of Investments.
Indemnifications — Under each 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 each fund. Additionally, in the normal course of business, each fund enters into agreements with service providers that may contain indemnification clauses. Each fund's maximum exposure under these agreements is unknown as this would involve future claims that may be made against each fund that have not yet occurred.
Investment Transactions and Income —  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.
Each fund may receive proceeds from litigation settlements. Any proceeds received from litigation involving portfolio holdings are reflected in the Statements 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 Statements of Operations.
Investment transactions are recorded on the trade date.  In determining the net gain or loss on securities sold, the cost of securities is determined on the identified cost basis.
Each fund may purchase or sell securities on a when-issued or delayed delivery basis.  In these extended settlement transactions, the receipt or delivery of the securities by the fund and related payments occur at a future date, usually beyond the customary settlement period. The price of such security and the date that the security will be settled are generally fixed at the time the transaction is negotiated. The value of the security varies with market fluctuations and for debt securities no interest accrues to the fund until settlement takes place. When the fund sells securities on a when-issued or delayed delivery basis, the fund typically owns or has the right to acquire securities equivalent in kind and amount to the securities sold. Purchase and sale commitments for when-issued or delayed delivery securities are held at carrying amount, which approximates fair value and are categorized as level 2 within the fair value hierarchy, and included in When-issued investments purchased and When-issued investments sold in the Statements of Assets and Liabilities, as applicable. Losses may arise due to changes in the value of the underlying securities prior to settlement date or if the counterparty does not perform under the contract’s terms, or if the issuer does not issue the securities due to political, economic or other factors.
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 — Each fund's custody fee may be reduced by a credit earned under an arrangement that measures the value of U.S. dollars deposited with the custodian by each fund. The amount of the credit, for the year ended March 31, 2024, is shown as a reduction of total expenses in the Statements of Operations.
Tax Matters and Distributions — Each 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. Each 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 each 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.

Notes to Financial Statements  - continued
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.
Book/tax differences primarily relate to defaulted bonds, amortization of premium and accretion of discount of debt securities, and treating a portion of the proceeds from redemptions as a distribution for tax purposes, as applicable to each fund.
The tax character of distributions declared to shareholders for the last two fiscal years is as follows:

Trustees’ and Officers’ Compensation — Each fund pays compensation to independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. Independent Trustees’ compensation is accrued daily and paid subsequent to each Trustee Board meeting. The funds do not pay compensation directly to Trustees or officers of each fund who are also officers of the investment adviser, all of whom receive remuneration from MFS for their services to each fund. Certain officers and Trustees of each fund are officers or directors of MFS, MFD, and MFSC.
Prior to December 31, 2001, each fund had an unfunded defined benefit plan (“DB plan”) for independent Trustees. As of December 31, 2001, the Board took action to terminate the DB plan with respect to then-current and any future independent Trustees, such that the DB plan covers only certain of those former independent Trustees who retired on or before December 31, 2001. The Alabama Fund, the Arkansas Fund, and the Georgia Fund no longer participate in the DB plan. The DB plan resulted in a pension expense for the following funds. These amounts are included in “Independent Trustees’ compensation” in the Statements of Operations for the year ended March 31, 2024:

(6)  Line of Credit
Each fund and certain other funds managed by MFS participate in a $1.45 billion unsecured committed line of credit of which $1.2 billion is reserved for use by each fund and certain other MFS U.S. funds. The line of credit is provided by a syndicate 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 highest of 1) Daily Simple SOFR (Secured Overnight Financing Rate) plus 0.10%, 2) the Federal Funds Effective Rate, or 3) the Overnight Bank Funding Rate, each 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. The line of credit expires on March 13, 2025 unless extended or renewed. In addition, each 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 rates equal to customary reference rates plus an agreed upon spread. For the year ended March 31, 2024, each fund’s commitment fee and interest expense were as follows and are included in “Miscellaneous” expense in the Statements of Operations:

Report of Independent Registered Public Accounting Firm 
To the Board of Trustees of MFS Municipal Series Trust and the Shareholders of MFS Alabama Municipal Bond Fund, MFS Arkansas Municipal Bond Fund, MFS California Municipal Bond Fund, MFS Georgia Municipal Bond Fund, MFS Maryland Municipal Bond Fund and MFS Massachusetts Municipal Bond Fund:
Opinion on the Financial Statements and Financial Highlights
We have audited the accompanying statements of assets and liabilities of MFS Alabama Municipal Bond Fund, MFS Arkansas Municipal Bond Fund, MFS California Municipal Bond Fund, MFS Georgia Municipal Bond Fund, MFS Maryland Municipal Bond Fund and MFS Massachusetts Municipal Bond Fund (the “Funds”), including the portfolios of investments, as of March 31, 2024, the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of each of the Funds as of March 31, 2024, and the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Funds are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Funds’ internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of March 31, 2024, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Statement Regarding Liquidity Risk Management Program 
Each fund has adopted and implemented a liquidity risk management program (the “Program”) as required by Rule 22e-4 under the Investment Company Act of 1940, as amended. Each fund’s Board of Trustees (the “Board”) has designated MFS as the administrator of the Program. The Program is reasonably designed to assess and manage the liquidity risk of each fund. Liquidity risk is the risk that each fund could not meet requests to redeem shares issued by each fund without significant dilution of remaining investors' interests.
MFS provided a written report to the Board for consideration at its March 2024 meeting that addressed the operation of the Program and provided an assessment of the adequacy and effectiveness of the Program during the period from January 1, 2023 to December 31, 2023 (the “Covered Period”). The report concluded that during the Covered Period the Program had operated effectively in all material respects and had adequately and effectively been implemented to assess and manage each fund’s liquidity risk. MFS also reported that there were no liquidity events that impacted each fund or its ability to timely meet redemptions without dilution to existing shareholders during the Covered Period.
There can be no assurance that the Program will achieve its objectives in the future. Further information on liquidity risk, and other principal risks to which an investment in each fund may be subject, can be found in each fund's prospectus.

(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. If none of the 3 rating agencies above assign a rating, but the security is rated by DBRS Morningstar, then the DBRS Morningstar rating is assigned. If none of the 4 rating agencies listed above rate the security, but the security is rated by the Kroll Bond Rating Agency (KBRA), then the KBRA rating 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 and fixed income derivatives that have not been rated by any rating agency. The fund may or may not have held all of these instruments on this date. 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. The Average Duration calculation reflects the impact of the equivalent exposure of derivative positions, if any. 
(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.
(m) In determining each 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 feature (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.
Cash & Cash Equivalents includes any cash, investments in money market funds, short-term securities, and other assets less liabilities. Please see the Statements of Assets and Liabilities for additional information related to the fund’s cash position and other assets and liabilities.
Percentages are based on net assets as of March 31, 2024.
The portfolio is actively managed and current holdings may be different.

(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. If none of the 3 rating agencies above assign a rating, but the security is rated by DBRS Morningstar, then the DBRS Morningstar rating is assigned. If none of the 4 rating agencies listed above rate the security, but the security is rated by the Kroll Bond Rating Agency (KBRA), then the KBRA rating 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 and fixed income derivatives that have not been rated by any rating agency. The fund may or may not have held all of these instruments on this date. 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. The Average Duration calculation reflects the impact of the equivalent exposure of derivative positions, if any. 
(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.
(m) In determining each 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 feature (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.

Management Review 
Summary of Results
For the twelve months ended March 31, 2024, the total return for the Class A shares, at net asset value, of the municipal bond funds of Mississippi, Pennsylvania, Virginia and West Virginia underperformed the return of the Bloomberg Municipal Bond Index, while the municipal bond funds of North Carolina, New York and South Carolina outperformed the same benchmark. The performance of the individual funds and the benchmark are set forth in the Performance Summary.
Market Environment
In response to the strongest inflationary episode in four decades, global central banks tightened monetary policy significantly during the reporting period, helping reduce price pressures, although more work remains to be done before inflation returns to target. Geopolitical strains remained high amid ongoing conflicts in Ukraine and in the Middle East, while relations between China and the US remained tense as the US sought to restrict the flow of advanced technologies to China and China looked to use its industrial overcapacity to increase exports to developed markets to bolster its slow-growing domestic economy. The conflict in the Middle East has resulted in trade flow disruptions between Asia and Europe as shipping traffic was routed away from the Red Sea.
Although inflation has yet to reach central banks’ targets, policymakers have telegraphed their intentions to begin cutting rates in the months ahead. The prospects for easier monetary policy along with resilient global economic growth have been supportive factors for risky assets, such as equities and high-yield bonds. Long-term interest rates moderated during the latter half of the period, although rising government debt levels remained a concern over the medium term. Advancements in artificial intelligence and the adoption of novel weight-loss drugs were two areas of focus for investors during the period.
Amid this eventful backdrop, the investment grade municipal market generated positive returns over the period. Securities in the lower-rated investment grade credit quality tiers and longer duration assets outperformed. Yields rose across the tax-exempt municipal curve, most notably in the short (within two years) segment. A positive for income-oriented investors, the yield (yield-to-worst) on the investment grade municipal index ended the period at 3.49%, well above its 5 and 10-year average.
Factors Affecting Performance
Across all funds, exposure to the power sector, for which the benchmark has no exposure, most notably within “D” and “CC” rated(r) securities, weakened performance relative to the Bloomberg Municipal Bond Index. A longer duration(d) stance also weighed on relative returns across all funds, as interest rates generally rose over the reporting period.
On the positive side, exposure to both the state and health care sectors contributed to relative performance across all funds. From a quality perspective, exposure to non-rated securities, which are not held in the benchmark, strengthened relative results. Additionally, favorable bond selection within “AA” rated debt issuers, across all funds except the municipal bond fund of Pennsylvania, also benefited relative returns.
Respectfully,
Portfolio Manager(s)
Michael Dawson
(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.
(r) Securities rated “BBB”, “Baa”, or higher are considered investment grade; securities rated “BB”, “Ba”, or below are considered non-investment grade. Ratings are assigned to underlying securities utilizing ratings from Moody's, Fitch, and Standard & Poor's 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. If none of the 3 rating agencies above assign a rating, but the security is rated by DBRS Morningstar, then the DBRS Morningstar rating is assigned. If none of the 4 rating agencies listed above rate the security, but the security is rated by the Kroll Bond Rating Agency (KBRA), then the KBRA rating is assigned. Ratings are shown in the S&P and Fitch scale (e.g., AAA). For securities that are not rated by any of the rating agencies, the security is considered Not Rated.

Performance Summary THROUGH 3/31/24
The following charts illustrate a representative class of each fund’s historical performance in comparison to its benchmark(s). Performance results include the deduction of the maximum applicable sales charge and reflect the percentage change in net asset value, including reinvestment of dividends and capital gains distributions. The performance of other share classes will be greater than or less than that of the class depicted below. Each fund's results have been compared to the Bloomberg Municipal Bond Index, a market capitalization-weighted index that measures the performance of the tax-exempt bond market. However, while this index is considered the benchmark for the performance of municipal bond funds, it is comprised of municipal bonds issued within the 50 states and the District of Columbia as well as U.S. territories and possessions such as Guam, Puerto Rico, and the Virgin Islands, while each of the funds invests a large percentage of its assets in municipal issuers of the state that is in the fund’s name. Benchmarks are unmanaged and may not be invested in directly. Benchmark returns do not reflect sales charges, commissions or expenses. (See Notes to Performance Summary.)
Performance data shown represents past performance and is no guarantee of future results. Investment return and principal value fluctuate so your shares, when sold, may be worth more or less than the original cost; current performance may be lower or higher than quoted. The performance shown does not reflect the deduction of taxes, if any, that a shareholder would pay on fund distributions or the redemption of fund shares.

Notes to Performance Summary
Average annual total return represents the average annual change in value for each share class for the periods presented. Life returns are presented where the share class has less than 10 years of performance history and represent the average annual total return from the class inception date to the stated period end date. As the fund's share classes may have different inception dates, the life returns may represent different time periods and may not be comparable. As a result, no comparative benchmark performance information is provided for life periods.

Performance Summary  - continued
Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers each fund's performance results would be less favorable. Please see the prospectus and financial statements for complete details.
Performance results do not include adjustments made for financial reporting purposes in accordance with U.S. generally accepted accounting principles and may differ from amounts reported in the financial highlights.  
A portion of the fund’s monthly distributions may be subject to state, federal, and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax.
From time to time the funds may receive proceeds from litigation settlements, without which performance would be lower.

Expense Tables 
Fund expenses borne by the shareholders during the period, October 1, 2023 through March 31, 2024
As a shareholder of the funds, you incur two types of costs: (1) transaction costs, including sales charges (loads) on certain purchase or redemption payments, and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other fund expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in the funds and to compare these costs with the ongoing costs of investing in other mutual funds.
These examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire period October 1, 2023 through March 31, 2024.
Actual Expenses
The first line for each share class in the following tables provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.
Hypothetical Example for Comparison Purposes
The second line for each share class in the following tables provides information about hypothetical account values and hypothetical expenses based on each fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not each fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in each fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.
Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second line for each share class in the tables is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Notes to Financial Statements 
(1)  Business and Organization
MFS Mississippi Municipal Bond Fund (Mississippi Fund), MFS New York Municipal Bond Fund (New York Fund), MFS North Carolina Municipal Bond Fund (North Carolina Fund), MFS Pennsylvania Municipal Bond Fund (Pennsylvania Fund), MFS South Carolina Municipal Bond Fund (South Carolina Fund), MFS Virginia Municipal Bond Fund (Virginia Fund), and MFS West Virginia Municipal Bond Fund (West Virginia Fund) are each a series of MFS Municipal Series Trust which is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. Each fund is a diversified series with the exception of Mississippi Fund and West Virginia Fund which are non-diversified.
Each 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 each fund’s Statement of Assets and Liabilities through the date that the financial statements were issued. Each fund invests primarily in municipal instruments, which generally trade in the over-the-counter market. The value of municipal instruments can be affected by changes in their actual or perceived credit quality. The credit quality of, and the ability to pay principal and interest when due by, an issuer of a municipal instrument depends on the credit quality of the entity supporting the municipal instrument, how essential any services supported by the municipal instrument are, the sufficiency of any revenues or taxes that support the municipal instrument, and/or the willingness or ability of the appropriate government entity to approve any appropriations necessary to support the municipal instrument. Municipal instruments may be supported by insurance which typically guarantees the timely payment of all principal and interest due on the underlying municipal instrument. The value of a municipal instrument can be volatile and significantly affected by adverse tax changes or court rulings, legislative or political changes, changes in specific or general market and economic conditions in the region or state where the instrument is issued, and the financial condition of municipal issuers and of municipal instrument insurers of which there are a limited number. Also, because many municipal instruments are issued to finance similar projects, conditions in certain industries can significantly affect the funds and the overall municipal market. 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 funds could be taxable to shareholders.
Balance Sheet Offsetting — Each 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, or similar agreement, does not result in an offset of reported amounts of financial assets and financial liabilities in the Statements of Assets and Liabilities across transactions between each fund and the applicable counterparty. Each 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 each fund, have been included in each fund’s Significant Accounting Policies note under the captions for each of the fund’s in-scope financial instruments and transactions.
Investment Valuations Subject to its oversight, the funds' Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of each fund’s investments to MFS as the funds' adviser, pursuant to each fund’s valuation policy and procedures which have been adopted by the adviser and approved by the Board. In accordance with Rule 2a-5 under the Investment Company Act of 1940, the Board of Trustees designated the adviser as the “valuation designee” of each fund. If the adviser, as valuation designee, determines that reliable market quotations are not readily available for an investment, the investment is valued at fair value as determined in good faith by the adviser in accordance with the adviser’s fair valuation policy and procedures.
Under each fund's valuation policy and procedures, 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. Open-end investment companies are generally valued at net asset value per share.
Under each fund’s valuation policy and procedures, market quotations are not considered to be readily available for debt instruments, floating rate loans, and many types of derivatives. These investments are generally valued at fair value based on information from third-party pricing services or otherwise determined by the adviser in accordance with the adviser’s fair valuation policy and procedures. 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. In determining values, third-party pricing services can utilize both transaction data and market information such as yield, quality, coupon rate, maturity, type of issue, trading characteristics, spreads and other market data. An investment may also be valued at fair value if the adviser determines that the investment’s value has been materially affected by 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 each fund’s net asset value, or after the halt 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 each 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 each fund’s net asset value may differ from quoted or published prices for the same investment. There can be no assurance that each fund could obtain the fair value assigned to an investment if it were to sell the investment at the same time at which each fund determines its net asset value per share.
Various inputs are used in determining the value of each 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. Each 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 significant unobservable inputs, which may include the adviser's own assumptions in determining the fair value of investments. The following is a summary of the levels used as of March 31, 2024 in valuing each fund's assets and liabilities:

Indemnifications — Under each 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 each fund. Additionally, in the normal course of business, each fund enters into agreements with service providers that may contain indemnification clauses. Each fund's maximum exposure under these agreements is unknown as this would involve future claims that may be made against each fund that have not yet occurred.
Investment Transactions and Income —  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.
Each fund may receive proceeds from litigation settlements. Any proceeds received from litigation involving portfolio holdings are reflected in the Statements 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 Statements of Operations.
Investment transactions are recorded on the trade date.  In determining the net gain or loss on securities sold, the cost of securities is determined on the identified cost basis.
Each fund may purchase or sell securities on a when-issued or delayed delivery basis.  In these extended settlement transactions, the receipt or delivery of the securities by the fund and related payments occur at a future date, usually beyond the customary settlement period. The price of such security and the date that the security will be settled are generally fixed at the time the transaction is negotiated. The value of the security varies with market fluctuations and for debt securities no interest accrues to the fund until settlement takes place. When the fund sells securities on a when-issued or delayed delivery basis, the fund typically owns or has the right to acquire securities equivalent in kind and amount to the securities sold. Purchase and sale commitments for when-issued or delayed delivery securities are held at carrying amount, which approximates fair value and are categorized as level 2 within the fair value hierarchy, and included in When-issued investments purchased and When-issued investments sold in the Statements of Assets and Liabilities, as applicable. Losses may arise due to changes in the value of the underlying securities prior to settlement date or if the counterparty does not perform under the contract’s terms, or if the issuer does not issue the securities due to political, economic or other factors.
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 — Each fund's custody fee may be reduced by a credit earned under an arrangement that measures the value of U.S. dollars deposited with the custodian by each fund. The amount of the credit, for the year ended March 31, 2024, is shown as a reduction of total expenses in the Statements of Operations.

Tax Matters and Distributions — Each 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. Each 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 each 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.
Book/tax differences primarily relate to defaulted bonds, amortization of premium and accretion of discount of debt securities, wash sale loss deferrals, and treating a portion of the proceeds from redemptions as a distribution for tax purposes, as applicable to each fund.
The tax character of distributions declared to shareholders for the last two fiscal years is as follows:

Multiple Classes of Shares of Beneficial Interest — Each fund offers multiple classes of shares, which differ in their respective distribution and service fees. Each fund's income and common expenses are allocated to shareholders based on the value of settled shares outstanding of each class. Each fund's realized and unrealized gain (loss) are allocated to shareholders based on the daily net assets of each class. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. Class B and Class C shares will convert to Class A shares approximately eight years after purchase. Each fund’s distributions declared to shareholders as reported in the Statements of Changes in Net Assets are presented by class as follows:

Trustees’ and Officers’ Compensation — Each fund pays compensation to independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. Independent Trustees’ compensation is accrued daily and paid subsequent to each Trustee Board meeting. The funds do not pay compensation directly to Trustees or officers of each fund who are also officers of the investment adviser, all of whom receive remuneration from MFS for their services to each fund. Certain officers and Trustees of each fund are officers or directors of MFS, MFD, and MFSC.
Prior to December 31, 2001, each fund had an unfunded defined benefit plan (“DB plan”) for independent Trustees. As of December 31, 2001, the Board took action to terminate the DB plan with respect to then-current and any future independent Trustees, such that the DB plan covers only certain of those former independent Trustees who retired on or before December 31, 2001. The Mississippi Fund, the New York Fund, and the Pennsylvania Fund no longer participate in the DB plan. The DB plan resulted in a pension expense for the following funds.

(6)  Line of Credit
Each fund and certain other funds managed by MFS participate in a $1.45 billion unsecured committed line of credit of which $1.2 billion is reserved for use by each fund and certain other MFS U.S. funds. The line of credit is provided by a syndicate 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 highest of 1) Daily Simple SOFR (Secured Overnight Financing Rate) plus 0.10%, 2) the Federal Funds Effective Rate, or 3) the Overnight Bank Funding Rate, each 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. The line of credit expires on March 13, 2025 unless extended or renewed. In addition, each 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 rates equal to customary reference rates plus an agreed upon spread. For the year ended March 31, 2024, each fund’s commitment fee and interest expense were as follows and are included in “Miscellaneous” expense in the Statements of Operations:

Report of Independent Registered Public Accounting Firm 
To the Board of Trustees of MFS Municipal Series Trust and the Shareholders of MFS Mississippi Municipal Bond Fund, MFS New York Municipal Bond Fund, MFS North Carolina Municipal Bond Fund, MFS Pennsylvania Municipal Bond Fund, MFS South Carolina Municipal Bond Fund, MFS Virginia Municipal Bond Fund and MFS West Virginia Municipal Bond Fund:
Opinion on the Financial Statements and Financial Highlights
We have audited the accompanying statements of assets and liabilities of MFS Mississippi Municipal Bond Fund, MFS New York Municipal Bond Fund, MFS North Carolina Municipal Bond Fund, MFS Pennsylvania Municipal Bond Fund, MFS South Carolina Municipal Bond Fund, MFS Virginia Municipal Bond Fund and MFS West Virginia Municipal Bond Fund (the “Funds”), including the portfolios of investments, as of March 31, 2024, the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of each of the Funds as of March 31, 2024, and the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Funds are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Funds’ internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of March 31, 2024, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Statement Regarding Liquidity Risk Management Program 
Each fund has adopted and implemented a liquidity risk management program (the “Program”) as required by Rule 22e-4 under the Investment Company Act of 1940, as amended. Each fund’s Board of Trustees (the “Board”) has designated MFS as the administrator of the Program. The Program is reasonably designed to assess and manage the liquidity risk of each fund. Liquidity risk is the risk that each fund could not meet requests to redeem shares issued by each fund without significant dilution of remaining investors' interests.
MFS provided a written report to the Board for consideration at its March 2024 meeting that addressed the operation of the Program and provided an assessment of the adequacy and effectiveness of the Program during the period from January 1, 2023 to December 31, 2023 (the “Covered Period”). The report concluded that during the Covered Period the Program had operated effectively in all material respects and had adequately and effectively been implemented to assess and manage each fund’s liquidity risk. MFS also reported that there were no liquidity events that impacted each fund or its ability to timely meet redemptions without dilution to existing shareholders during the Covered Period.
There can be no assurance that the Program will achieve its objectives in the future. Further information on liquidity risk, and other principal risks to which an investment in each fund may be subject, can be found in each fund's prospectus.

Information About Fund Contracts and Legal Claims
Each fund has entered into contractual arrangements with an investment adviser, administrator, distributor, shareholder servicing agent, and custodian who each provide services to the fund. Unless expressly stated otherwise, shareholders are not parties to, or intended beneficiaries of these contractual arrangements, and these contractual arrangements are not intended to create any shareholder right to enforce them against the service providers or to seek any remedy under them against the service providers, either directly or on behalf of the fund.

Of the dividends paid from net investment income during the fiscal year, the following percentages were designated as exempt interest dividends for federal income tax purposes.

(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. If none of the 3 rating agencies above assign a rating, but the security is rated by DBRS Morningstar, then the DBRS Morningstar rating is assigned. If none of the 4 rating agencies listed above rate the security, but the security is rated by the Kroll Bond Rating Agency (KBRA), then the KBRA rating 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 and fixed income derivatives that have not been rated by any rating agency. The fund may or may not have held all of these instruments on this date. 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. The Average Duration calculation reflects the impact of the equivalent exposure of derivative positions, if any. 
(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.
(m) In determining each 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 feature (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.
(o) Less than 0.1%.
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.
Percentages are based on net assets as of March 31, 2024.

Management Review
Summary of Results
For the twelve months ended March 31, 2024, Class A shares of the MFS Municipal Intermediate Fund (fund) provided a total return of 3.82%, at net asset value. This compares with a return of 2.62% for the fund’s benchmark, the Bloomberg Municipal 1-15 Year Index.
Market Environment
In response to the strongest inflationary episode in four decades, global central banks tightened monetary policy significantly during the reporting period, helping reduce price pressures, although more work remains to be done before inflation returns to target. Geopolitical strains remained high amid ongoing conflicts in Ukraine and in the Middle East, while relations between China and the US remained tense as the US sought to restrict the flow of advanced technologies to China and China looked to use its industrial overcapacity to increase exports to developed markets to bolster its slow-growing domestic economy. The conflict in the Middle East has resulted in trade flow disruptions between Asia and Europe as shipping traffic was routed away from the Red Sea.
Although inflation has yet to reach central banks’ targets, policymakers have telegraphed their intentions to begin cutting rates in the months ahead. The prospects for easier monetary policy along with resilient global economic growth have been supportive factors for risky assets, such as equities and high-yield bonds. Long-term interest rates moderated during the latter half of the period, although rising government debt levels remained a concern over the medium term. Advancements in artificial intelligence and the adoption of novel weight-loss drugs were two areas of focus for investors during the period.
Amid this eventful backdrop, the investment grade municipal market generated positive returns over the period. Securities in the lower-rated investment grade credit quality tiers and longer duration assets outperformed. Yields rose across the tax-exempt municipal curve, most notably in the short (within two years) segment. A positive for income-oriented investors, the yield (yield-to-worst) on the investment grade municipal index ended the period at 3.49%, well above its 5 and 10-year average.
Factors Affecting Performance
Relative to the Bloomberg Municipal 1-15 Year Index, the fund’s asset allocation decisions contributed to performance. From a quality perspective, the fund’s overweight allocation to “BBB” rated(r) securities, and its exposure to non-rated and “BB” rated issues, for which the benchmark has no exposure, strengthened relative returns. From a sector perspective, the fund’s greater allocation to the industrial revenue sector and lesser allocation to the state sector benefited relative performance. Additionally, favorable security selection within “A” rated bonds, particularly across the health care, transportation, and leasing sectors, and within “AA” rated bonds, notably within the education sector, also helped the fund’s relative results.
From a quality perspective, the fund’s exposure to “D” rated bonds, for which the benchmark has no exposure, held back relative performance during the year. Security selection within “BBB” rated bonds, particularly within the special tax sector, also

weighed on relative returns. Although on an absolute basis, longer duration assets outperformed shorter duration securities within the benchmark, on a relative basis, the fund's longer duration(d) stance weakened performance as interest rates generally rose over the reporting period.

(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.

Expense Table
Fund expenses borne by the shareholders during the period,
October 1, 2023 through March 31, 2024
As a shareholder of the fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on certain purchase or redemption payments, and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds.
The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period October 1, 2023 through March 31, 2024.
Actual Expenses
The first line for each share class in the following table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.
Hypothetical Example for Comparison Purposes
The second line for each share class in the following table provides information about hypothetical account values and hypothetical expenses based on the fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.
Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second line for each share class in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

If these transaction costs had been included, your costs would have been higher.

Notes to Financial Statements
(1) Business and Organization
MFS Municipal Intermediate Fund (the fund) is a diversified series of MFS Municipal Series Trust (the trust). The trust is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as an open-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, which generally trade in the over-the-counter market. The value of municipal instruments can be affected by changes in their actual or perceived credit quality. The credit quality of, and the ability to pay principal and interest when due by, an issuer of a municipal instrument depends on the credit quality of the entity supporting the municipal instrument, how essential any services supported by the municipal instrument are, the sufficiency of any revenues or taxes that support the municipal instrument, and/or the willingness or ability of the appropriate government entity to approve any appropriations necessary to support the municipal instrument. Municipal instruments may be supported by insurance which typically guarantees the timely payment of all principal and interest due on the underlying municipal instrument. The value of a municipal instrument can be volatile and significantly affected by adverse tax changes or court rulings, legislative or political changes, changes in specific or general market and economic conditions in the region where the instrument is issued, and the financial condition of municipal issuers and of municipal instrument insurers of which there are a limited number. Also, because many municipal instruments are issued to finance similar projects, conditions in certain industries can significantly affect the fund and the overall municipal market. 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.
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, or similar 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
45

Notes to Financial Statements  - continued
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 Subject to its oversight, the fund's Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of the fund’s investments to MFS as the fund's adviser, pursuant to the fund’s valuation policy and procedures which have been adopted by the adviser and approved by the Board. In accordance with Rule 2a-5 under the Investment Company Act of 1940, the Board of Trustees designated the adviser as the “valuation designee” of the fund. If the adviser, as valuation designee, determines that reliable market quotations are not readily available for an investment, the investment is valued at fair value as determined in good faith by the adviser in accordance with the adviser’s fair valuation policy and procedures.
Under the fund's valuation policy and procedures, 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. Open-end investment companies are generally valued at net asset value per share.
Under the fund’s valuation policy and procedures, market quotations are not considered to be readily available for debt instruments, floating rate loans, and many types of derivatives. These investments are generally valued at fair value based on information from third-party pricing services or otherwise determined by the adviser in accordance with the adviser’s fair valuation policy and procedures. 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. In determining values, third-party pricing services can utilize both transaction data and market information such as yield, quality, coupon rate, maturity, type of issue, trading characteristics, spreads and other market data. An investment may also be valued at fair value if the adviser determines that the investment’s value has been materially affected by 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 halt 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,
46

Notes to Financial Statements  - continued
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 significant unobservable inputs, which may include the adviser's own assumptions in determining the fair value of investments. The following is a summary of the levels used as of March 31, 2024 in valuing the fund's assets and liabilities:
Financial Instruments Level 1 Level 2 Level 3 Total
Municipal Bonds $— $176,382,701 $— $176,382,701
U.S. Corporate Bonds 629,089 629,089
Mutual Funds 48,668 48,668
Total $48,668 $177,011,790 $— $177,060,458
For further information regarding security characteristics, see the Portfolio of 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 —  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.
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.
Investment transactions are recorded on the trade date.  In determining the net gain or loss on securities sold, the cost of securities is determined on the identified cost basis.
The fund may purchase or sell securities on a when-issued or delayed delivery basis.  In these extended settlement transactions, the receipt or delivery of the securities by the fund and related payments occur at a future date, usually beyond the customary settlement period. The price of such security and the date that the security will be settled are generally fixed at the time the transaction is negotiated. The value of the
47

Notes to Financial Statements  - continued
security varies with market fluctuations and for debt securities no interest accrues to the fund until settlement takes place. When the fund sells securities on a when-issued or delayed delivery basis, the fund typically owns or has the right to acquire securities equivalent in kind and amount to the securities sold. Purchase and sale commitments for when-issued or delayed delivery securities are held at carrying amount, which approximates fair value and are categorized as level 2 within the fair value hierarchy, and included in When-issued investments purchased and When-issued investments sold in the Statement of Assets and Liabilities, as applicable. Losses may arise due to changes in the value of the underlying securities prior to settlement date or if the counterparty does not perform under the contract’s terms, or if the issuer does not issue the securities due to political, economic or other factors.
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 — The fund's custody fee may be reduced by a credit earned under an arrangement that measures the value of U.S. dollars deposited with the custodian by the fund. The amount of the credit, for the year ended March 31, 2024, is shown as a reduction of total expenses in the Statement of Operations.
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.
Book/tax differences primarily relate to defaulted bonds and amortization of premium and accretion of discount of debt securities.

Multiple Classes of Shares of Beneficial Interest — The fund offers multiple classes of shares, which differ in their respective distribution and service fees. The fund's income and common expenses are allocated to shareholders based on the value of settled shares outstanding of each class. The fund's realized and unrealized gain (loss) are allocated to shareholders based on the daily net assets of each class. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. Class C shares will convert to Class A

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 the following annual rates based on the fund's average daily net assets:
Up to $1 billion 0.35%
In excess of $1 billion and up to $2.5 billion 0.325%
In excess of $2.5 billion 0.30%
MFS has agreed in writing to reduce its management fee by a specified amount if certain MFS mutual fund assets exceed thresholds agreed to by MFS and the fund's Board of Trustees. MFS has also agreed in writing to waive at least 0.01% of its management fee as part of this agreement. The agreement to waive at least 0.01% of the management fee will continue until modified by the fund's Board of Trustees, but such agreement will continue at least until July 31, 2024. For the year ended March 31, 2024, this management fee reduction amounted to $19,540, which is included in the reduction of total expenses in the Statement of Operations. The management fee incurred for the year ended March 31, 2024 was equivalent to an annual effective rate of 0.34% of the fund's average daily net assets.
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, certain tax reclaim recovery expenses (including contingency fees and closing agreement expenses), and investment-related expenses, such that total fund operating expenses do not exceed the following rates annually of each class’s average daily net assets:
Classes
A C I R6
0.70% 1.45% 0.45% 0.38%
This written agreement will continue until modified by the fund’s Board of Trustees, but such agreement will continue at least until July 31, 2024. For the year ended March 31, 2024, this reduction amounted to $215,824, which is included in the reduction of total expenses in the Statement of Operations.
Distributor — MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of MFS, as distributor, received $2,197 for the year ended March 31, 2024, as its portion of the initial sales charge on sales of Class A shares of the fund.

Notes to Financial Statements  - continued
The Board of Trustees has adopted a distribution plan for certain share classes pursuant to Rule 12b-1 of the Investment Company Act of 1940.
The fund's distribution plan provides that the fund will pay MFD for services provided by MFD and financial intermediaries in connection with the distribution and servicing of certain share classes. One component of the plan is a distribution fee paid to MFD and another component of the plan is a service fee paid to MFD. MFD may subsequently pay all, or a portion, of the distribution and/or service fees to financial intermediaries. The distribution and service fees are computed daily and paid monthly.

For the year ended March 31, 2024, the fee was $2,473, which equated to 0.0016% annually of the fund's average daily net assets. MFSC also receives reimbursement from the fund for out-of-pocket expenses, sub-accounting and other shareholder servicing costs which may be paid to affiliated and unaffiliated service providers. Class R6 shares do not incur sub-accounting fees. For the year ended March 31, 2024, these out-of-pocket expenses, sub-accounting and other shareholder servicing costs amounted to $99,018.

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. The administrative services fee is computed daily and paid monthly. The administrative services fee incurred for the year ended March 31, 2024 was equivalent to an annual effective rate of 0.0210% of the fund's average daily net assets.
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. Independent Trustees’ compensation is accrued daily and paid subsequent to each Trustee Board meeting. 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 from MFS for their services to the fund. Certain officers and Trustees of the fund are officers or directors of MFS, MFD, and MFSC.
Other — 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. This money market fund does not pay a management fee to MFS but does incur investment and operating costs.

(6) Line of Credit
The fund and certain other funds managed by MFS participate in a $1.45 billion unsecured committed line of credit of which $1.2 billion is reserved for use by the fund and certain other MFS U.S. funds. The line of credit is provided by a syndicate 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 highest of 1) Daily Simple SOFR (Secured Overnight Financing Rate) plus 0.10%, 2) the Federal Funds Effective Rate, or 3) the Overnight Bank Funding Rate, each 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. The line of credit expires on March 13, 2025 unless extended or renewed. 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 rates equal to customary reference rates plus an agreed upon spread. For the year ended March 31, 2024, the fund’s commitment fee and interest expense were $748 and $0, respectively, and are included in “Miscellaneous” expense in the Statement of Operations.

(8) LIBOR Transition
The London Interbank Offered Rate (LIBOR) was intended to represent the rate at which contributing banks may obtain short-term borrowings from each other in the London interbank market. Certain of the fund's investments, payment obligations, and financing terms were historically based on LIBOR. In 2017, the United Kingdom Financial Conduct Authority (FCA) announced plans to transition away from LIBOR by the end of 2021. LIBOR's administrator, ICE Benchmark Administration (IBA), ceased publication (on a representative basis) of many of its LIBOR settings as of December 31, 2021 and ceased publication (on a representative basis) of the remaining U.S. dollar LIBOR settings as of June 30, 2023. In addition, global regulators announced that, with limited exceptions, no new LIBOR-based contracts should be entered into after 2021. Although the FCA has announced that it will require the IBA to continue to publish certain select LIBOR rates on a synthetic basis after the relevant cessation dates, such synthetic rates are not considered to be representative of the underlying market and economic reality they are intended to measure, are expected to be published for a limited time period, and are intended solely for use on a limited basis for legacy transactions.
Regulators and industry groups have implemented measures to facilitate the transition away from LIBOR and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (SOFR). SOFR is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities in the repurchase agreement (repo) market. SOFR is published in various forms including as a daily, compounded, and forward-looking term rate. The transition to alternative reference rates may affect the liquidity and valuation of investments that were tied to LIBOR or other interbank offered rates and may lead to other consequences affecting securities and credit markets more broadly. For example, while some investments that were tied to LIBOR provided for an alternative or “fallback” rate-setting methodology in the event LIBOR is not available, there is uncertainty regarding the effectiveness of any such alternative methodologies to replace LIBOR and certain investments tied to LIBOR may not have fallback provisions. While legislation passed in the United States facilitates by operation of law the replacement of U.S. dollar LIBOR settings in certain legacy instruments with a specified replacement rate, such as SOFR, there is uncertainty
54

Notes to Financial Statements  - continued
regarding the effectiveness of such legislation. There also remains uncertainty regarding the willingness and ability of parties to add or amend fallback provisions in certain other legacy instruments maturing after the cessation of the applicable LIBOR rates, which could create market and litigation risk. 
It is difficult to quantify or predict the impact on the fund resulting from the transition from LIBOR to alternative reference rates and the potential effects of the transition from LIBOR on the fund, or on certain instruments in which the fund invests, are not known. The transition process may involve, among other things, increased volatility or illiquidity in markets for instruments that relied on LIBOR to determine interest rates. The transition may also result in a reduction in value of certain LIBOR-related investments held by the fund or reduce the effectiveness of related transactions such as hedges. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates, as well as other unforeseen effects, could have an adverse impact on the fund's performance. 
With respect to the fund’s accounting for investments, including investments in certain debt instruments and derivatives, as well as borrowings by the fund and any other contractual arrangements of the fund that undergo reference rate-related modifications as a result of the transition, management has and will continue to rely upon the relief provided by FASB Codification Topic 848 – Reference Rate Reform (Topic 848). The guidance in Topic 848 permits the fund to account for such contract modifications made on or before December 31, 2024 as a continuation of the existing contracts. The situation remains fluid, and management believes, based on best available information, that the impact of the transition will not be material to the fund.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of MFS Municipal Series Trust and the Shareholders of MFS Municipal Intermediate Fund:
Opinion on the Financial Statements and Financial Highlights
We have audited the accompanying statement of assets and liabilities of MFS Municipal Intermediate Fund (the “Fund”), including the portfolio of investments, as of March 31, 2024, the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the two years in the period then ended and for the period from May 18, 2021 (the commencement of the Fund’s investment operations) through March 31, 2022, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of March 31, 2024, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the two years in the period then ended, and for the period from May 18, 2021 (the commencement of the Fund’s investment operations) through March 31, 2022, in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund's financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights.
56

Report of Independent Registered Public Accounting Firm – continued
Our procedures included confirmation of securities owned as of March 31, 2024, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Statement Regarding Liquidity Risk Management Program
The fund has adopted and implemented a liquidity risk management program (the “Program”) as required by Rule 22e-4 under the Investment Company Act of 1940, as amended. The fund’s Board of Trustees (the “Board”) has designated MFS as the administrator of the Program. The Program is reasonably designed to assess and manage the liquidity risk of the fund. Liquidity risk is the risk that the fund could not meet requests to redeem shares issued by the fund without significant dilution of remaining investors' interests.
MFS provided a written report to the Board for consideration at its March 2024 meeting that addressed the operation of the Program and provided an assessment of the adequacy and effectiveness of the Program during the period from January 1, 2023 to December 31, 2023 (the “Covered Period”). The report concluded that during the Covered Period the Program had operated effectively in all material respects and had adequately and effectively been implemented to assess and manage the fund’s liquidity risk. MFS also reported that there were no liquidity events that impacted the fund or its ability to timely meet redemptions without dilution to existing shareholders during the Covered Period.
There can be no assurance that the Program will achieve its objectives in the future. Further information on liquidity risk, and other principal risks to which an investment in the fund may be subject, can be found in the prospectus.

(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. If none of the 3 rating agencies above assign a rating, but the security is rated by DBRS Morningstar, then the DBRS Morningstar rating is assigned. If none of the 4 rating agencies listed above rate the security, but the security is rated by the Kroll Bond Rating Agency (KBRA), then the KBRA rating 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 and fixed income derivatives that have not been rated by any rating agency. The fund may or may not have held all of these instruments on this date. The fund is not rated by these agencies.

Portfolio Composition - continued
(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. The Average Duration calculation reflects the impact of the equivalent exposure of derivative positions, if any. 
(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.
(m) In determining each 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 feature (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.
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 equivalent exposure from currency derivatives and/or any offsets to derivative positions and/or the leverage created through the issuance of self-deposited inverse floaters and may be negative.
Percentages are based on net assets as of March 31, 2024.
The portfolio is actively managed and current holdings may be different.

Management Review
Summary of Results
For the twelve months ended March 31, 2024, Class A shares of the MFS Municipal Income Fund (fund) provided a total return of 4.23%, at net asset value. This compares with a return of 3.13% for the fund’s benchmark, the Bloomberg Municipal Bond Index.
Market Environment
In response to the strongest inflationary episode in four decades, global central banks tightened monetary policy significantly during the reporting period, helping reduce price pressures, although more work remains to be done before inflation returns to target. Geopolitical strains remained high amid ongoing conflicts in Ukraine and in the Middle East, while relations between China and the US remained tense as the US sought to restrict the flow of advanced technologies to China and China looked to use its industrial overcapacity to increase exports to developed markets to bolster its slow-growing domestic economy. The conflict in the Middle East has resulted in trade flow disruptions between Asia and Europe as shipping traffic was routed away from the Red Sea.
Although inflation has yet to reach central banks’ targets, policymakers have telegraphed their intentions to begin cutting rates in the months ahead. The prospects for easier monetary policy along with resilient global economic growth have been supportive factors for risky assets, such as equities and high-yield bonds. Long-term interest rates moderated during the latter half of the period, although rising government debt levels remained a concern over the medium term. Advancements in artificial intelligence and the adoption of novel weight-loss drugs were two areas of focus for investors during the period.
Amid this eventful backdrop, the investment grade municipal market generated positive returns over the period. Securities in the lower-rated investment grade credit quality tiers and longer duration assets outperformed. Yields rose across the tax-exempt municipal curve, most notably in the short (within two years) segment. A positive for income-oriented investors, the yield (yield-to-worst) on the investment grade municipal index ended the period at 3.49%, well above its 5 and 10-year average.
Factors Affecting Performance
Relative to the Bloomberg Municipal Bond Index, the fund’s asset allocation decisions contributed to performance. From a sector perspective, the fund’s greater exposure to both the health care and industrial revenue sectors, and its underweight exposure to the state sector, boosted relative returns. From a quality perspective, the fund’s allocation to non-rated and “BB” rated(r) bonds, for which the benchmark has no exposure, and its greater exposure to “BBB” rated bonds also helped relative results. Favorable bond selection within “AA” and “A” rated bonds was another positive factor for relative performance. Additionally, the fund’s positioning along the yield curve(y) further supported relative returns.

Management Review - continued
Conversely, from a quality perspective, the fund’s exposure to both “D” and “CC” rated bonds held back relative performance. A longer duration(d) stance also weakened the fund’s relative returns as interest rates generally rose over the reporting period.
Respectfully,
Portfolio Manager(s)
Jason Kosty, Megan Poplowski, and Geoffrey Schechter
(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.
(r) Securities rated “BBB”, “Baa”, or higher are considered investment grade; securities rated “BB”, “Ba”, or below are considered non-investment grade. Ratings are assigned to underlying securities utilizing ratings from Moody's, Fitch, and Standard & Poor's 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. If none of the 3 rating agencies above assign a rating, but the security is rated by DBRS Morningstar, then the DBRS Morningstar rating is assigned. If none of the 4 rating agencies listed above rate the security, but the security is rated by the Kroll Bond Rating Agency (KBRA), then the KBRA rating is assigned. Ratings are shown in the S&P and Fitch scale (e.g., AAA). For securities that are not rated by any of the rating agencies, the security is considered Not Rated.
(y) A yield curve graphically depicts the yields of different maturity bonds of the same credit quality and type; a normal yield curve is upward sloping, with short-term rates lower than long-term rates.

Performance Summary THROUGH 3/31/24
The following chart illustrates a representative class of the fund’s historical performance in comparison to its benchmark(s). Performance results include the deduction of the maximum applicable sales charge and reflect the percentage change in net asset value, including reinvestment of dividends and capital gains distributions. The performance of other share classes will be greater than or less than that of the class depicted below. Benchmarks are unmanaged and may not be invested in directly. Benchmark returns do not reflect sales charges, commissions or expenses. (See Notes to Performance Summary.)
Performance data shown represents past performance and is no guarantee of future results. Investment return and principal value fluctuate so your shares, when sold, may be worth more or less than the original cost; current performance may be lower or higher than quoted. The performance shown does not reflect the deduction of taxes, if any, that a shareholder would pay on fund distributions or the redemption of fund shares.

Notes to Performance Summary
Average annual total return represents the average annual change in value for each share class for the periods presented. Life returns are presented where the share class has less than 10 years of performance history and represent the average annual total return from the class inception date to the stated period end date. As the fund's share classes may have different inception dates, the life returns may represent different time periods and may not be comparable. As a result, no comparative benchmark performance information is provided for life periods.
Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance results would be less favorable. Please see the prospectus and financial statements for complete details.
Performance results do not include adjustments made for financial reporting purposes in accordance with U.S. generally accepted accounting principles and may differ from amounts reported in the financial highlights.  
A portion of the fund’s monthly distributions may be subject to state, federal, and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax.
From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower.

Expense Table
Fund expenses borne by the shareholders during the period,
October 1, 2023 through March 31, 2024
As a shareholder of the fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on certain purchase or redemption payments, and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds.
The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period October 1, 2023 through March 31, 2024.
Actual Expenses
The first line for each share class in the following table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.
Hypothetical Example for Comparison Purposes
The second line for each share class in the following table provides information about hypothetical account values and hypothetical expenses based on the fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.
Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second line for each share class in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Hypothetical (h) 1.26% $1,000.00 $1,018.70 $6.36
(h) 5% class return per year before expenses.
(p) “Expenses Paid During Period” are equal to each class’s annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by 183/366 (to reflect the one-half year period).  Expenses paid do not include any applicable sales charges (loads). If these transaction costs had been included, your costs would have been higher.
Notes to Expense Table
Expense ratios include 0.03% of investment related expenses from self-deposited inverse floaters (as described in Note 2 of the Notes to Financial Statements) that are outside of the expense limitation arrangement (See Note 3 of the Notes to Financial Statements).

Notes to Financial Statements
(1) Business and Organization
MFS Municipal Income Fund (the fund) is a diversified series of MFS Municipal Series Trust which is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as an open-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, which generally trade in the over-the-counter market. The value of municipal instruments can be affected by changes in their actual or perceived credit quality. The credit quality of, and the ability to pay principal and interest when due by, an issuer of a municipal instrument depends on the credit quality of the entity supporting the municipal instrument, how essential any services supported by the municipal instrument are, the sufficiency of any revenues or taxes that support the municipal instrument, and/or the willingness or ability of the appropriate government entity to approve any appropriations necessary to support the municipal instrument. Municipal instruments may be supported by insurance which typically guarantees the timely payment of all principal and interest due on the underlying municipal instrument. The value of a municipal instrument can be volatile and significantly affected by adverse tax changes or court rulings, legislative or political changes, changes in specific or general market and economic conditions in the region where the instrument is issued, and the financial condition of municipal issuers and of municipal instrument insurers of which there are a limited number. Also, because many municipal instruments are issued to finance similar projects, conditions in certain industries can significantly affect the fund and the overall municipal market. 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.
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, or similar 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
129

Notes to Financial Statements  - continued
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 Subject to its oversight, the fund's Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of the fund’s investments to MFS as the fund's adviser, pursuant to the fund’s valuation policy and procedures which have been adopted by the adviser and approved by the Board. In accordance with Rule 2a-5 under the Investment Company Act of 1940, the Board of Trustees designated the adviser as the “valuation designee” of the fund. If the adviser, as valuation designee, determines that reliable market quotations are not readily available for an investment, the investment is valued at fair value as determined in good faith by the adviser in accordance with the adviser’s fair valuation policy and procedures.
Under the fund's valuation policy and procedures, 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. Open-end investment companies are generally valued at net asset value per share.
Under the fund’s valuation policy and procedures, market quotations are not considered to be readily available for debt instruments, floating rate loans, and many types of derivatives. These investments are generally valued at fair value based on information from third-party pricing services or otherwise determined by the adviser in accordance with the adviser’s fair valuation policy and procedures. 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. In determining values, third-party pricing services can utilize both transaction data and market information such as yield, quality, coupon rate, maturity, type of issue, trading characteristics, spreads and other market data. An investment may also be valued at fair value if the adviser determines that the investment’s value has been materially affected by 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 halt 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,
130

Notes to Financial Statements  - continued
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 significant unobservable inputs, which may include the adviser's own assumptions in determining the fair value of investments. The following is a summary of the levels used as of March 31, 2024 in valuing the fund's assets and liabilities:
Financial Instruments Level 1 Level 2 Level 3 Total
Municipal Bonds $— $5,045,454,133 $— $5,045,454,133
U.S. Corporate Bonds 20,306,018 20,306,018
Mutual Funds 65,685,343 65,685,343
Total $65,685,343 $5,065,760,151 $— $5,131,445,494
For further information regarding security characteristics, see the Portfolio of Investments.
Inverse Floaters — The fund invests in municipal inverse floating rate securities in the form of self-deposited secondary market inverse floaters and primary market inverse floaters, both of which have variable rates of interest that typically move in the opposite direction of short-term rates. A self-deposited secondary market inverse floater is created when the fund transfers a municipal bond from its portfolio to a special purpose trust (“the trust”) and causes the trust to issue (a) inverse floaters to be held by the fund and (b) floating rate certificates to be held by third parties. The floating rate certificates usually pay tax-exempt interest at short-term rates that reset weekly and the holders of those certificates typically have the option to tender at par plus accrued interest. Self-deposited secondary market inverse floaters are accounted for as secured borrowings, with the municipal bonds transferred to the trust being reflected as fund investments and the amounts owed to floating rate certificate holders being reflected as fund liabilities in the Statement of Assets and Liabilities as “Payable to the holders of the floating rate certificates”. The carrying value of that liability as reported in the fund’s Statement of Assets and Liabilities approximates its fair value which would be considered level 2 under the fair value hierarchy. 
At March 31, 2024, the fund’s payable to the holders of the floating rate certificates was $27,078,332 and the related weighted average interest rate on the settled floating rate certificates issued by the trust was 3.67%. For the year ended March 31, 2024, the average payable to the holders of the settled floating rate certificates was $30,292,131 at a weighted average interest rate of 3.88%. Interest expense and fees, which are recorded as incurred, include interest payments made to the holders of the floating rate certificates and associated fees. For the year ended March 31, 2024, the related interest expense and fees amounted to $1,405,997 which is included in “Interest expense and fees” in the Statement of Operations. Primary market inverse floaters held by the fund are presented as fund investments and are not accounted for as secured borrowings.
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,
131

Notes to Financial Statements  - continued
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 —  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.
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.
Investment transactions are recorded on the trade date.  In determining the net gain or loss on securities sold, the cost of securities is determined on the identified cost basis.
The fund may purchase or sell securities on a when-issued or delayed delivery basis.  In these extended settlement transactions, the receipt or delivery of the securities by the fund and related payments occur at a future date, usually beyond the customary settlement period. The price of such security and the date that the security will be settled are generally fixed at the time the transaction is negotiated. The value of the security varies with market fluctuations and for debt securities no interest accrues to the fund until settlement takes place. When the fund sells securities on a when-issued or delayed delivery basis, the fund typically owns or has the right to acquire securities equivalent in kind and amount to the securities sold. Purchase and sale commitments for when-issued or delayed delivery securities are held at carrying amount, which approximates fair value and are categorized as level 2 within the fair value hierarchy, and included in When-issued investments purchased and When-issued investments sold in the Statement of Assets and Liabilities, as applicable. Losses may arise due to changes in the value of the underlying securities prior to settlement date or if the counterparty does not perform under the contract’s terms, or if the issuer does not issue the securities due to political, economic or other factors.
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 — The fund's custody fee may be reduced by a credit earned under an arrangement that measures the value of U.S. dollars deposited with the custodian by the fund. The amount of the credit, for the year ended March 31, 2024, is shown as a reduction of total expenses in the Statement of Operations.
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.
Book/tax differences primarily relate to defaulted bonds, amortization of premium and accretion of discount of debt securities, and treating a portion of the proceeds from redemptions as a distribution for tax purposes.
The tax character of distributions declared to shareholders for the last two fiscal years is as follows:
  Year ended
3/31/24
Year ended

Total distributions $173,337,074 $134,897,656
The federal tax cost and the tax basis components of distributable earnings were as follows:
As of 3/31/24  
Cost of investments $5,216,923,317
Gross appreciation 108,091,353
Gross depreciation (220,647,508)

133

Notes to Financial Statements  - continued
As of March 31, 2024, the fund had capital loss carryforwards available to offset future realized gains. These net capital losses may be carried forward indefinitely and their character is retained as short-term and/or long-term losses. Such losses are characterized as follows:
Short-Term $(77,788,327)
Long-Term (122,887,298)
Total $(200,675,625)
Multiple Classes of Shares of Beneficial Interest — The fund offers multiple classes of shares, which differ in their respective distribution and service fees. The fund's income and common expenses are allocated to shareholders based on the value of settled shares outstanding of each class. The fund's realized and unrealized gain (loss) are allocated to shareholders based on the daily net assets of each class. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. Class B and B1 shares will convert to Class A and A1 shares, respectively, approximately eight years after purchase. Class C shares will convert to Class A shares approximately ten years after purchase. The fund’s distributions declared to shareholders as reported in the Statements of Changes in Net Assets are presented by class as follows:
  Year ended
3/31/24

(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 the following annual rates based on the fund's average daily net assets:
Up to $1.3 billion 0.40%
In excess of $1.3 billion and up to $2 billion 0.37%
In excess of $2 billion and up to $5 billion 0.35%
In excess of $5 billion and up to $10 billion 0.34%
In excess of $10 billion 0.33%
MFS has agreed in writing to reduce its management fee by a specified amount if certain MFS mutual fund assets exceed thresholds agreed to by MFS and the fund's Board of Trustees. MFS has also agreed in writing to waive at least 0.01% of its management fee as part of this agreement. The agreement to waive at least 0.01% of the management fee will continue until modified by the fund's Board of Trustees, but such agreement will continue at least until July 31, 2024. For the year ended March 31, 2024, this management fee reduction amounted to $622,325, which is included in the
134

Notes to Financial Statements  - continued
reduction of total expenses in the Statement of Operations. The management fee incurred for the year ended March 31, 2024 was equivalent to an annual effective rate of 0.35% of the fund's average daily net assets.
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, certain tax reclaim recovery expenses (including contingency fees and closing agreement expenses), and investment-related expenses (including interest expense and fees associated with investments in inverse floating rate instruments), such that total fund operating expenses do not exceed the following rates annually of each class’s average daily net assets:
Classes
A B C I R6 A1 B1
0.73% 1.48% 1.48% 0.48% 0.42% 0.48% 1.23%
This written agreement will continue until modified by the fund’s Board of Trustees, but such agreement will continue at least until July 31, 2024. For the year ended March 31, 2024, 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.
Distributor — MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of MFS, as distributor, received $61,599 and $419 for the year ended March 31, 2024, as its portion of the initial sales charge on sales of Class A and Class A1 shares of the fund, respectively.
The Board of Trustees has adopted a distribution plan for certain share classes pursuant to Rule 12b-1 of the Investment Company Act of 1940.
The fund's distribution plan provides that the fund will pay MFD for services provided by MFD and financial intermediaries in connection with the distribution and servicing of certain share classes. One component of the plan is a distribution fee paid to MFD and another component of the plan is a service fee paid to MFD. MFD may subsequently pay all, or a portion, of the distribution and/or service fees to financial intermediaries. The distribution and service fees are computed daily and paid monthly.

135

Notes to Financial Statements  - continued
writing to reduce the Class B1 service fee rate to 0.00% for all Class B1 shares. This written agreement will continue until modified by the fund’s Board of Trustees, but such agreement will continue at least until July 31, 2024. For the year ended March 31, 2024, this reduction amounted to $136 and is included in the reduction of total expenses in the Statement of Operations. MFD has voluntarily agreed to rebate a portion of each class's 0.25% service fee attributable to accounts for which there is no financial intermediary specified on the account except for accounts attributable to MFS or its affiliates' seed money. For the year ended March 31, 2024, this rebate amounted to $478 for Class A shares, and is included in the reduction of total expenses in the Statement of Operations.
Certain Class A and Class A1 shares are subject to a contingent deferred sales charge (CDSC) in the event of a shareholder redemption within 18 months of purchase. Class B and Class B1 shares are subject to a CDSC in the event of a shareholder redemption within six years of purchase. Class C shares are subject to a CDSC in the event of a shareholder redemption within 12 months of purchase. All contingent deferred sales charges are paid to MFD and during the year ended March 31, 2024, were as follows:
  Amount
Class A $142,206
Class B 386
Class C 3,337
Class A1
Class B1
Shareholder Servicing Agent — MFS Service Center, Inc. (MFSC), a wholly-owned subsidiary of MFS, receives a fee from the fund for its services as shareholder servicing agent calculated as a percentage of the average daily net assets of the fund as determined periodically under the supervision of the fund's Board of Trustees. For the year ended March 31, 2024, the fee was $150,669, which equated to 0.0031% annually of the fund's average daily net assets. MFSC also receives reimbursement from the fund for out-of-pocket expenses, sub-accounting and other shareholder servicing costs which may be paid to affiliated and unaffiliated service providers. Class R6 shares do not incur sub-accounting fees. For the year ended March 31, 2024, these out-of-pocket expenses, sub-accounting and other shareholder servicing costs amounted to $2,997,053.
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. The administrative services fee is computed daily and paid monthly. The administrative services fee incurred for the year ended March 31, 2024 was equivalent to an annual effective rate of 0.0127% of the fund's average daily net assets.
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. Independent Trustees’ compensation is accrued daily and paid subsequent to each Trustee Board meeting. The
136

Notes to Financial Statements  - continued
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 from MFS for their services to the fund. Certain officers and Trustees of the fund are officers or directors of MFS, MFD, and MFSC.
Prior to December 31, 2001, the fund had an unfunded defined benefit plan (“DB plan”) for independent Trustees.  As of December 31, 2001, the Board took action to terminate the DB plan with respect to then-current and any future independent Trustees, such that the DB plan covers only certain of those former independent Trustees who retired on or before December 31, 2001. The DB plan resulted in a pension expense of $2,382 and is included in “Independent Trustees’ compensation” in the Statement of Operations for the year ended March 31, 2024.  The deferred retirement benefits compensation fee is accrued daily and paid monthly.
Other — 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. This money market fund does not pay a management fee to MFS but does incur investment and operating costs.
On August 3, 2022, MFS redeemed 24 shares of Class R6 for an aggregate amount of $200.
At March 31, 2024, MFS held approximately 97% of the outstanding shares of Class B1.
During the year ended March 31, 2024, pursuant to a policy adopted by the Board of Trustees and designed to comply with Rule 17a-7 under the Investment Company Act of 1940 (the “Act”) and relevant guidance, the fund engaged in purchase and sale transactions with funds and accounts for which MFS serves as investment adviser or sub-adviser (“cross-trades”) which amounted to $18,483,632 and $595,529, respectively. The sales transactions resulted in net realized gains (losses) of $(36,887).

(6) Line of Credit
The fund and certain other funds managed by MFS participate in a $1.45 billion unsecured committed line of credit of which $1.2 billion is reserved for use by the fund and certain other MFS U.S. funds. The line of credit is provided by a syndicate 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 highest of 1) Daily Simple SOFR (Secured Overnight Financing Rate) plus 0.10%, 2) the Federal Funds Effective Rate, or 3) the Overnight Bank Funding Rate, each 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. The line of credit expires on March 13, 2025 unless extended or renewed. 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 rates equal to customary reference rates plus an agreed upon spread. For the year ended March 31, 2024, the fund’s commitment fee and interest expense were $24,270 and $0, respectively, and are included in “Interest expense and fees” in the Statement of Operations.
(7) Investments in Affiliated Issuers

(8) LIBOR Transition
The London Interbank Offered Rate (LIBOR) was intended to represent the rate at which contributing banks may obtain short-term borrowings from each other in the London interbank market. Certain of the fund's investments, payment obligations, and financing terms were historically based on LIBOR. In 2017, the United Kingdom Financial Conduct Authority (FCA) announced plans to transition away from LIBOR by the end of 2021. LIBOR's administrator, ICE Benchmark Administration (IBA), ceased publication (on a representative basis) of many of its LIBOR settings as of December 31, 2021 and ceased publication (on a representative basis) of the remaining U.S. dollar LIBOR settings as of June 30, 2023. In addition, global regulators announced that, with limited exceptions, no new LIBOR-based contracts should be entered into after 2021. Although the FCA has announced that it will require the IBA to continue to publish certain select LIBOR rates on a synthetic basis after the relevant cessation dates, such synthetic rates are not considered to be representative of the underlying market and economic reality they are intended to measure, are expected to be published for a limited time period, and are intended solely for use on a limited basis for legacy transactions.
Regulators and industry groups have implemented measures to facilitate the transition away from LIBOR and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (SOFR). SOFR is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities in the repurchase agreement (repo) market. SOFR is published in various forms including as a daily, compounded, and forward-looking term rate. The transition to alternative reference rates may affect the liquidity and valuation of investments that were tied to LIBOR or other interbank offered rates and may lead to other consequences affecting securities and credit markets more broadly. For example, while some investments that were tied to LIBOR provided for an alternative or “fallback” rate-setting methodology in the event LIBOR is not available, there is uncertainty regarding the effectiveness of any such alternative methodologies to replace LIBOR and certain investments tied to LIBOR may not have fallback provisions. While legislation passed in the United States facilitates by operation of law the replacement of U.S. dollar LIBOR settings in certain legacy instruments with a specified replacement rate, such as SOFR, there is uncertainty regarding the effectiveness of such legislation. There also remains uncertainty regarding the willingness and ability of parties to add or amend fallback provisions in certain other legacy instruments maturing after the cessation of the applicable LIBOR rates, which could create market and litigation risk. 
It is difficult to quantify or predict the impact on the fund resulting from the transition from LIBOR to alternative reference rates and the potential effects of the transition from LIBOR on the fund, or on certain instruments in which the fund invests, are not known. The transition process may involve, among other things, increased volatility or illiquidity in markets for instruments that relied on LIBOR to determine interest rates. The transition may also result in a reduction in value of certain LIBOR-related
140

Notes to Financial Statements  - continued
investments held by the fund or reduce the effectiveness of related transactions such as hedges. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates, as well as other unforeseen effects, could have an adverse impact on the fund's performance. 
With respect to the fund’s accounting for investments, including investments in certain debt instruments and derivatives, as well as borrowings by the fund and any other contractual arrangements of the fund that undergo reference rate-related modifications as a result of the transition, management has and will continue to rely upon the relief provided by FASB Codification Topic 848 – Reference Rate Reform (Topic 848). The guidance in Topic 848 permits the fund to account for such contract modifications made on or before December 31, 2024 as a continuation of the existing contracts. The situation remains fluid, and management believes, based on best available information, that the impact of the transition will not be material to the fund.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of MFS Municipal Series Trust and the Shareholders of MFS Municipal Income Fund:
Opinion on the Financial Statements and Financial Highlights
We have audited the accompanying statement of assets and liabilities of MFS Municipal Income Fund (the “Fund”), including the portfolio of investments, as of March 31, 2024, the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of March 31, 2024, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund's financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights.
142

Report of Independent Registered Public Accounting Firm – continued
Our procedures included confirmation of securities owned as of March 31, 2024, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Statement Regarding Liquidity Risk Management Program
The fund has adopted and implemented a liquidity risk management program (the “Program”) as required by Rule 22e-4 under the Investment Company Act of 1940, as amended. The fund’s Board of Trustees (the “Board”) has designated MFS as the administrator of the Program. The Program is reasonably designed to assess and manage the liquidity risk of the fund. Liquidity risk is the risk that the fund could not meet requests to redeem shares issued by the fund without significant dilution of remaining investors' interests.
MFS provided a written report to the Board for consideration at its March 2024 meeting that addressed the operation of the Program and provided an assessment of the adequacy and effectiveness of the Program during the period from January 1, 2023 to December 31, 2023 (the “Covered Period”). The report concluded that during the Covered Period the Program had operated effectively in all material respects and had adequately and effectively been implemented to assess and manage the fund’s liquidity risk. MFS also reported that there were no liquidity events that impacted the fund or its ability to timely meet redemptions without dilution to existing shareholders during the Covered Period.
There can be no assurance that the Program will achieve its objectives in the future. Further information on liquidity risk, and other principal risks to which an investment in the fund may be subject, can be found in the prospectus.

Item 1(b):

Not applicable.

ITEM 2. CODE OF ETHICS.

The Registrant has adopted a Code of Ethics (the "Code") pursuant to Section 406 of the Sarbanes-Oxley Act and as defined in Form N-CSR that applies to the Registrant's principal executive officer and principal financial and accounting officer. During the period covered by this report, the Registrant has not amended any provision in the Code that relates to an element of the Code's definition enumerated in paragraph

(b)of Item 2 of this Form N-CSR. During the period covered by this report, the Registrant did not grant a waiver, including an implicit

waiver, from any provision of the Code. David L. DiLorenzo (Principal Executive Officer) and James O. Yost (Principal Financial Officer) were the two persons covered by the Code prior to April 1, 2024. Beginning April 1, 2024, David L. DiLorenzo (Principal Executive Officer) and Kasey L. Phillips (Principal Financial Officer) are the two persons covered by the Code.

A copy of the Code is attached hereto as EX-99.COE.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

Messrs. Steven E. Buller and Clarence Otis, Jr., members of the Audit Committee, have been determined by the Board of Trustees in their reasonable business judgment to meet the definition of "audit committee financial expert" as such term is defined in Form N-CSR. In addition, Messrs. Buller and Otis are "independent" members of the Audit Committee (as such term has been defined by the Securities and Exchange Commission in regulations implementing Section 407 of the Sarbanes-Oxley Act of 2002). The Securities and Exchange Commission has stated that the designation of a person as an audit committee financial expert pursuant to this Item 3 on the Form N-CSR does not impose on such a person any duties, obligations or liability that are greater than the duties, obligations or liability imposed on such person as a member of the Audit Committee and the Board of Trustees in the absence of such designation or identification.

 

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

Items 4(a) through 4(d) and 4(g):

*This amount reflects the fees billed to MFS and MFS Related Entities for non-audit services relating directly to the operations and financial reporting of the Funds (portions of which services also related to the operations and financial reporting of other funds within the MFS Funds complex).

# This amount reflects the aggregate fees billed by Deloitte, as the case may be, for non-audit services rendered to the Funds and for non-audit services rendered to MFS and the MFS Related Entities.

1 The fees included under "Audit-Related Fees" are fees related to assurance and related services that are reasonably related to the performance of the audit or review of financial statements, but not reported under ''Audit Fees,'' including accounting consultations, agreed-upon procedure reports, attestation reports, comfort letters and internal control reviews.

2 The fees included under "Tax Fees" are fees associated with tax compliance, tax advice and tax planning, including services relating to the filing or amendment of federal, state or local income tax returns, regulated investment company qualification reviews and tax distribution and analysis.

3 The fees included under "All Other Fees" are fees for products and services provided by Deloitte other than those reported under "Audit Fees," "Audit-Related Fees" and "Tax Fees".

4 Certain fees reported in 2023 have been restated in this filing from those reported in the Registrant's filing for the reporting period ended March 31, 2023.

Item 4(e)(1):

Set forth below are the policies and procedures established by the Audit Committee of the Board of Trustees relating to the pre- approval of audit and non-audit related services:

To the extent required by applicable law, pre-approval by the Audit Committee of the Board is needed for all audit and permissible non-audit services rendered to the Fund and all permissible non-audit services rendered to MFS or MFS Related Entities if the services relate directly to the operations and financial reporting of the Registrant. Pre-approval is currently on an engagement-by-engagement basis. In the event pre-approval of such services is necessary between regular meetings of the Audit Committee and it is not practical to wait to seek pre-approval at the next regular meeting of the Audit Committee, pre-approval of such services may be referred to the Chair of the Audit Committee for approval; provided that the Chair may not pre-approve any individual engagement for such services exceeding $50,000 or multiple engagements for such services in the aggregate exceeding $100,000 in each period between regular meetings of the Audit Committee. Any engagement pre-approved by the Chair between regular meetings of the Audit Committee shall be presented for ratification by the entire Audit Committee at its next regularly scheduled meeting.

Item 4(e)(2):

None, or 0%, of the services relating to the Audit-Related Fees, Tax Fees and All Other Fees paid by the Fund and MFS and MFS Related Entities relating directly to the operations and financial reporting of the Registrant disclosed above were approved by the audit committee pursuant to paragraphs (c)(7)(i)(C) of Rule 2-01 of Regulation S-X (which permits audit committee approval after the start of the engagement with respect to services other than audit, review or attest services, if certain conditions are satisfied).

Item 4(f):

Not applicable.

 

Item 4(h):

The Registrant's Audit Committee has considered whether the provision by a Registrant's independent registered public accounting firm of non-audit services to MFS and MFS Related Entities that were not pre-approved by the Committee (because such services did not relate directly to the operations and financial reporting of the Registrant) was compatible with maintaining the independence of the independent registered public accounting firm as the Registrant's principal auditors.

Item 4(i):

Not applicable.

Item 4(j):

Not applicable.

 

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS.

Not applicable to the Registrant.

ITEM 6. INVESTMENTS

A schedule of investments for each series covered by this Form N-CSR is included as part of the report to shareholders of such series under Item 1(a) of this Form N-CSR.

ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

Not applicable to the Registrant.

ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

Not applicable to the Registrant.

ITEM 9. PURCHASES OF EQUITY SECURITIES BY CLOSED-END MANAGEMENT INVESTMENT COMPANY AND AFFILIATED PURCHASERS.

Not applicable to the Registrant.

ITEM 10. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

There were no material changes to the procedures by which shareholders may send recommendations to the Board for nominees to the Registrant's Board since the Registrant last provided disclosure as to such procedures in response to the requirements of Item 407 (c)(2)(iv) of Regulation S-K or this Item.

ITEM 11. CONTROLS AND PROCEDURES.

(a)Based upon their evaluation of the effectiveness of the registrant's disclosure controls and procedures (as defined in Rule 30a-3(c) under the Investment Company Act of 1940 (the "Act")) as conducted within 90 days of the filing date of this report on Form N-CSR, the Registrant's principal financial officer and principal executive officer have concluded that those disclosure controls and procedures provide reasonable assurance that the material information required to be disclosed by the Registrant on this report is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms.

(b)There were no changes in the Registrant's internal controls over financial reporting (as defined in Rule 30a-3(d) under the Act) that occurred during the period covered by the report that have materially affected, or are reasonably likely to materially affect, the Registrant's internal control over financial reporting.

ITEM 12. DISCLOSURE OF SECURITIES LENDING ACTIVITIES FOR CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

Not applicable to the Registrant.

ITEM 13. RECOVERY OF ERRONEOUSLY AWARDED COMPENSATION.

Not Applicable.

ITEM 14. EXHIBITS.

(a)(1) Any code of ethics, or amendment thereto, that is the subject of the disclosure required by Item 2, to the extent that the registrant intends to satisfy the Item 2 requirements through filing of an exhibit: Attached hereto as EX-99.COE.

(2)A separate certification for each principal executive officer and principal financial officer of the registrant as required by Rule 30a-2(a) under the Act (17 CFR 270.30a-2): Attached hereto as EX-99.302CERT.

(3)Any written solicitation to purchase securities under Rule 23c-1 under the Act (17 CFR 270.23c-1) sent or given during the period covered by the report by or on behalf of the registrant to 10 or more persons. Not applicable.

(4)Change in the registrant's independent public accountant. Not applicable.

 

(b)If the report is filed under Section 13(a) or 15(d) of the Exchange Act, provide the certifications required by Rule 30a-2(b) under the Act (17 CFR 270.30a-2(b)), Rule 13a-14(b) or Rule 15d-14(b) under the Exchange Act (17 CFR 240.13a-14(b) or 240.15d-14(b)) and Section 1350 of Chapter 63 of Title 18 of the United States Code (18 U.S.C. 1350) as an exhibit. A certification furnished pursuant to this paragraph will not be deemed "filed" for the purposes of Section 18 of the Exchange Act (15 U.S.C. 78r), or otherwise subject to the liability of that section. Such certification will not be deemed to be incorporated by reference into any filing under the Securities Act of 1933 or the Exchange Act, except to the extent that the registrant specifically incorporates it by reference. Attached hereto as EX-99.906CERT.
