Shames] Jeffrey L. Shames Dear Shareholders, When we talk to you about the information you want from MFS(R), you tell us you're looking for answers to three basic questions: 1. How is my money being managed, over both the short and the long term? 2. What's going on in the market, and how will that affect me? 3. How can I get more out of my relationship with my investment professional? Traditionally, we've attempted to answer these and other questions through a range of printed materials sent through the mail, including statements and annual and semiannual reports. As the Internet has reached an ever-larger percentage of households, however, we and most other investment management firms have come to believe that the Web can be an additional -- and potentially more effective -- way to communicate with investors. The Internet holds the promise of near-instantaneous delivery, communication when you want it rather than when we mail it, easy access to the specific information you want, and an experience customized to each investor. With the relaunch of our Web site, WWW.MFS.COM, earlier this year, we believe we've moved a giant step closer to delivering the Internet's promise and created a site that we're committed to improving every day. Our site now makes it easy for you to find answers to your three basic questions. HOW IS MY MONEY BEING MANAGED? One of the most exciting features of our site is MFS(R) Interactive(SM): One click to an expert(SM) -- a series of video interviews with MFS portfolio managers and executives. Located in the "Investor Education" section of the site, MFS Interactive uses video streamed over the Web to allow you to see and hear from the people who are managing your money, to give you greater insight into our investment approach and our response to market conditions. MFS Interactive includes "Meet the Manager" interviews that cover the background and investment style of a particular portfolio manager, as well as other Webcasts that cover a specific fund or investment topic. WHAT'S GOING ON IN THE MARKET, AND HOW WILL THAT AFFECT ME? In our view, the tougher the market, the more you need to hear from the people who are managing your money -- and the past year or so has certainly been one of the toughest markets in recent memory. We think the immediacy of the Web provides an ideal way to communicate with you frequently and to offer our views on the current volatility and uncertainty in the market. On your "My MFS" homepage, in many MFS Interactive interviews, and in the "News & Commentary" section of the site, you'll find our views on the current situation and our market outlook. Our goal is to help you understand what's going on and help you make decisions based on facts and market history, rather than on the emotion of the moment. HOW CAN I GET MORE OUT OF MY RELATIONSHIP WITH MY INVESTMENT PROFESSIONAL? Perhaps your best resource in a tough market is your own investment professional. This is the person who may have the best understanding of your financial goals and your unique financial situation. In our view, the Web is incredible at delivering information, but it cannot take the place of an investment professional working with you to incorporate that information into a long-range financial plan -- a plan that may help you weather market volatility and help you work toward reaching your own financial goals. To a large degree, the MFS Web site is about preparing you to have a deeper dialogue with your investment professional. We believe that if we can help you "do your homework," you'll be able to spend less time with your investment professional simply getting information and more time creating a financial plan and making investment decisions. On a final note, we want to assure you that our commitment to the Internet does not signal a lessening of our commitment to other forms of communication. If you're not yet connected to the Web, rest assured that we will continue to strive to deliver outstanding communications in print and on the phone, as well as electronically. We hope, however, that as we continue to improve our site, we will give you more and more incentive to take advantage of the opportunities that the Web offers investors. For some time, I've ended my letters to you by saying that we appreciate your confidence in MFS and welcome any questions or comments you may have. With the relaunched WWW.MFS.COM, there is now an easy way for you to e-mail us those questions or comments and receive a reply. Simply click on "Contact Us" at the top of our homepage. We look forward to hearing from you. Respectfully, /s/ Jeffrey L. Shames Jeffrey L. Shames Chairman and Chief Executive Officer MFS Investment Management(R) May 15, 2001 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed. MANAGEMENT REVIEW AND OUTLOOK Dear Shareholders, For the six months ended April 30, 2001, the trust provided a total return of 9.64% based on its beginning and ending stock market prices and assuming the reinvestment of any distributions paid during the period. The trust's total return based on its net asset value (NAV) was 6.49%. These returns compare to returns of 6.30% and 1.26%, respectively, for the trust's benchmarks, the Salomon Brothers Medium Term (1- to 10-year) Treasury Government Sponsored Index (the Salomon Index), and the J.P. Morgan Non-Dollar Government Bond Index (the Morgan Index). The Salomon Index includes bonds issued by the U.S. government or by government agencies with a maturity range greater than or equal to one year, and less than 10 years. The Morgan Index is an unmanaged aggregate index of actively traded government bonds issued from 12 countries (excluding the United States) with remaining maturities of at least one year. A very proactive program of cuts in interest rates by the Federal Reserve Board (the Fed) highlighted the period. With inflation remaining benign during the period, the Fed turned its focus toward easing monetary policy in order to support growth. Overall, the Fed cut the fed funds rate by two percentage points during the period, including two surprise cuts of 0.50 percentage points implemented between regularly scheduled meetings. By acting this dramatically, we think the Fed demonstrated its forcefulness and indicated its intent to do whatever it takes to sustain growth. A sharp decline in corporate spending -- particularly for technology products and services -- seemed to be the main culprit that slowed economic growth. While consumer spending and construction remained strong, consumer confidence waned in the face of rising unemployment. During the period, sharp declines in short-term interest rates caused the yield curve -- a representation of the difference between short- and long-term rates -- to steepen. Within this backdrop, we've positioned the portfolio to take advantage of such a scenario. That approach called for a "bulleted" structure, where we targeted certain parts of the yield curve, including more exposure to bonds with maturities in the one- to three-year range. As far as sector allocation was concerned, we underweighted mortgage-backed securities (MBSs) substantially. Within a falling-rate environment, MBSs are unattractive due to increased refinancing activity. When interest rates fall, mortgage holders tend to pay off their loans early in order to take advantage of lower borrowing costs, and the holder of the MBS is then left to re-invest the principal at lower prevailing rates. Looking at the portfolio's international component, it's important to note that we only venture overseas if we feel alternatives there offer the opportunity to outperform domestic bonds. That said, we devoted only a small portion of the portfolio to both developed and developing country bonds because we held a very favorable view of the opportunities available in the United States. Within the developed world, we favored bonds offered by the dollar-bloc countries, including the United States, Australia, New Zealand, and Canada. These markets performed best among government issuers in 2000. We also kept a very small position in Europe. Overall, Europe has been less appealing to us because growth there has been stronger than in the United States for the first time since 1991, with the ensuing inflation making it difficult for the European Central Bank to justify interest rate cuts. Greece performed well due to the positive effects of its inclusion into the European Monetary Union (EMU). We avoided Japan because yields there were very low and would not have provided us with adequate income, in our opinion. Our small emerging market position was largely focused on very short-term Mexican paper, a higher-quality investment that was meant to add diversity to the portfolio. Going forward, we believe a main issue will be whether or not businesses will be able to work through an economic downturn and resume capital expenditures in the technology area without unemployment going that much higher. Any surge in the jobless rate would dampen consumer spending both for those who have lost their jobs as well as for those who have feared losing them. Fortunately, the fiscal and monetary policies that have characterized the first few months of 2001 seem to be geared toward increasing economic growth. The tax cut that has worked its way through Congress could provide a substantial stimulus to growth. In addition, we believe the Fed has made it clear through both its words and its actions that it stands ready to lend support to the economy. If growth strengthens in the United States, we might add investments in European bonds if trends there indicate that growth is slowing from the peak levels we saw during the period.

OBJECTIVE: To preserve capital and provide high current income. NEW YORK STOCK EXCHANGE SYMBOL: MIN -------------------------------------------------------------------------------- PERFORMANCE SUMMARY -------------------------------------------------------------------------------- (For the six months ended April 30, 2001) NET ASSET VALUE PER SHARE October 31, 2000 $7.06 April 30, 2001 $7.25 NEW YORK STOCK EXCHANGE PRICE October 31, 2000 $6.36 March 2, 2001 (high)* $6.94 November 13, 2000 (low)* $6.31 April 30, 2001 $6.74 *For the six months ended April 30, 2001 RISK CONSIDERATIONS Investments in foreign and emerging market securities may be unfavorably affected by interest-rate and currency-exchange-rate changes, as well as by market, economic, and political conditions of the countries where investments are made. There may be greater returns but also greater risk than with U.S. investments. The trust may invest in derivative securities which may include futures and options. These types of hedging instruments can increase price fluctuation. The trust is nondiversified and has more risk than a portfolio that is diversified. The trust invests in a limited number of securities and may have more risk because a change in one security's value may have a more significant effect on the trust's net asset value. An investment in the trust is not a complete investment program. Government guarantees apply to the underlying securities only and not to the prices and yields of the managed portfolio. The trust may invest in mortgage-backed securities, which are subject to unique interest and maturity risks. When interest rates fall, mortgages may be paid early through refinancing, which may shorten the expected maturity of these securities. Alternaively, when interest rates rise, mortgages are not likely to be paid early, which may lengthen the expected maturity of these securities. Therefore, during times of fluctuating interest rates, these factors may cause the value of mortgage-backed securities to increase or decrease more than those of other fixed-income securities. These risks may increase share price volatility. See the prospectus for details. NUMBER OF SHAREHOLDERS As of April 30, 2001, our records indicate that there are 10,528 registered shareholders and approximately 57,300 shareholders owning trust shares in "street" name, such as through brokers, banks, and other financial intermediaries. If you are a "street" name shareholder and wish to directly receive our reports, which contain important information about the trust, please write or call: State Street Bank and Trust Company P.O. Box 8200 Boston, MA 02266-8200 1-800-637-2304 DIVIDEND REINVESTMENT AND CASH PURCHASE PLAN MFS offers a Dividend Reinvestment and Cash Purchase Plan that allows you to reinvest either all of the distributions paid by the trust or only the long- term capital gains. Purchases are made at the market price unless that price exceeds the net asset value (the shares are trading at a premium). If the shares are trading at a premium, purchases will be made at a discounted price of either the net asset value or 95% of the market price, whichever is greater. Twice each year you can also buy shares. Investments from $100 to $2,500 can be made in January and July on the 15th of the month or shortly thereafter. If your shares are in the name of a brokerage firm, bank, or other nominee, you can ask the firm or nominee to participate in the plan on your behalf. If the nominee does not offer the plan, you may wish to request that your shares be re-registered in your own name so that you can participate. There is no service charge to reinvest distributions, nor are there brokerage charges for shares issued directly by the trust. However, when shares are bought on the New York Stock Exchange or otherwise on the open market, each participant pays a pro rata share of the commissions. The automatic reinvestment of distributions does not relieve you of any income tax that may be payable (or required to be withheld) on the distributions. To enroll in or withdraw from the plan, or if you have any questions call 1-800-637-2304 any business day from 8 a.m. to 8 p.m. Eastern time. Please have available the name of the trust and your account and Social Security numbers. For certain types of registrations, such as corporate accounts, instructions must be submitted in writing. Please call for additional details. When you withdraw, you can receive the value of the reinvested shares in one of two ways: a check for the value of the full and fractional shares, or a certificate for the full shares and a check for the fractional shares.

See notes to financial statements. NOTES TO FINANCIAL STATEMENTS (Unaudited) (1) Business and Organization MFS Intermediate Income Trust (the trust) is a non-diversified series of MFS 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 a closed-end management investment company. (2) Significant Accounting Policies General - The preparation of financial statements in conformity with 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 revenues and expenses during the reporting period. Actual results could differ from those estimates. The trust can invest in foreign securities. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. Investment Valuations - Debt securities (other than short-term obligations which mature in 60 days or less), including listed issues, forward foreign currency exchange contracts, and swap agreements, are valued on the basis of valuations furnished by dealers or by a pricing service with consideration to factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data, without exclusive reliance upon exchange or over-the- counter prices. Short-term obligations, which mature in 60 days or less, are valued at amortized cost, which approximates market value. Options contracts listed on commodities exchanges are reported at market value using closing settlement prices. Over-the-counter options on securities are valued by brokers. Over-the-counter currency options are valued through the use of a pricing model which takes into account foreign currency exchange spot and forward rates, implied volatility, and short-term repurchase rates. Securities for which there are no such quotations or valuations are valued in good faith by the Trustees. Repurchase Agreements - The trust may enter into repurchase agreements with institutions that the trust's investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The trust requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the trust to obtain those securities in the event of a default under the repurchase agreement. The trust monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the trust under each such repurchase agreement. The trust, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. Foreign Currency Translation - Investment valuations, other assets, and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. Deferred Trustee Compensation - Under a Deferred Compensation Plan (the Plan) independent Trustees may elect to defer receipt of all or a portion of their annual compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of the trust or other MFS trust selected by the Trustee. Deferred amounts represent an unsecured obligation of the trust until distributed in accordance with the Plan. Written Options - The trust may write call or put options in exchange for a premium. The premium is initially recorded as a liability, which is subsequently adjusted to the current value of the option contract. When a written option expires, the trust realizes a gain equal to the amount of the premium received. When a written call option is exercised or closed, the premium received is offset against the proceeds to determine the realized gain or loss. When a written put option is exercised, the premium reduces the cost basis of the security purchased by the trust. The trust, as writer of an option, may have no control over whether the underlying securities may be sold (call) or purchased (put) and, as a result, bears the market risk of an unfavorable change in the price of the securities underlying the written option. In general, written call options may serve as a partial hedge against decreases in value in the underlying securities to the extent of the premium received. Written options may also be used as part of an income producing strategy reflecting the view of the trust's management on the direction of interest rates. Security Loans - State Street Bank and Trust Company ("State Street") and Chase Manhattan Bank ("Chase"), as lending agents, may loan the securities of the trust to certain qualified institutions (the "Borrowers") approved by the trust. The loans are collateralized at all times by cash and/or U.S. Treasury securities in an amount at least equal to the market value of the securities loaned. State Street provides the trust with indemnification against Borrower default. The trust bears the risk of loss with respect to the investment of cash collateral. Cash collateral is invested in short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the trust and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the trust and the lending agent. Income from securities lending is included in interest income on the Statement of Operations. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. At April 30, 2001, the value of securities loaned was $202,094,979. These loans were collateralized by cash of $206,150,728, which was invested in the following short-term obligations: ISSUER SHARES VALUE ------------------------------------------------------------------------------ Navigator Securities Lending Prime Portfolio 206,150,728 $206,150,728 Forward Foreign Currency Exchange Contracts - The trust may enter into forward foreign currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. The trust may enter into forward foreign currency exchange contracts for hedging purposes as well as for non-hedging purposes. For hedging purposes, the trust may enter into contracts to deliver or receive foreign currency it will receive from or require for its normal investment activities. The trust may also use contracts in a manner intended to protect foreign currency-denominated securities from declines in value due to unfavorable exchange rate movements. For non-hedging purposes, the trust may enter into contracts with the intent of changing the relative exposure of the trust's portfolio of securities to different currencies to take advantage of anticipated changes. The forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any gains or losses are recorded as unrealized until the contract settlement date. On contract settlement date, the gains or losses are recorded as realized gains or losses on foreign currency transactions. Investment Transactions and Income - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and original issue discount is amortized or accreted for financial statement and tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex- dividend or ex-interest date in an amount equal to the value of the security on such date. Some securities may be purchased on a "when-issued" or "forward delivery" basis, which means that the securities will be delivered to the trust at a future date, usually beyond customary settlement time. The trust will adopt the provisions of the AICPA Audit and Accounting Guide for Investment Companies, as revised, effective for fiscal years beginning after December 15, 2000. As required, the trust will begin amortizing premiums on debt securities effective November 1, 2001. Prior to this date, the trust did not amortize premiums on debt securities. The cumulative effect of this accounting change will have no impact on the total net assets of the trust. The impact of this accounting change has not been determined, but will result in a decrease to cost of securities and a corresponding increase in net unrealized appreciation. Fees Paid Indirectly - The trust's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the trust. This amount is shown as a reduction of total expenses on the Statement of Operations. Tax Matters and Distributions - The trust's policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The trust distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in capital. Differences in the recognition or classification of income between the financial statements and tax earnings and profits, which result in temporary over-distributions for financial statement purposes, are classified as distributions in excess of net investment income or net realized gains. At April 30, 2001, the trust, for federal income tax purposes, had a capital loss carryforward of $60,026,544 which may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on October 31, 2008, ($11,439,294), October 31, 2007, ($11,376,973), October 31, 2006, ($13,874,621), October 31, 2004, ($645,525), October 31, 2003, ($6,526,984), and October 31, 2002, ($16,163,147). (3) Transactions with Affiliates Investment Adviser - The trust has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.32% of the trust's average daily net assets and 5.65% of investment income. The trust pays no compensation directly to its Trustees who are officers of the investment adviser, or to officers of the trust, all of whom receive remuneration for their services to the trust from MFS. Certain officers and Trustees of the trust are officers or directors of MFS and MFS Service Center, Inc. (MFSC). Included in Trustees' compensation is a net periodic pension expense of $27,716 for the period ended April 30, 2001. Administrator - The trust has an administrative services agreement with MFS to provide the trust with certain financial, legal, shareholder servicing, compliance, and other administrative services. As a partial reimbursement for the cost of providing these services, the trust pays MFS an administrative fee at the following annual percentages of the trust's average daily net assets: First $2 billion 0.0175% Next $2.5 billion 0.0130% Next $2.5 billion 0.0005% In excess of $7 billion 0.0000% Transfer Agent - MFSC acts as registrar and dividend disbursing agent for the Trust. The agreement provides that the Trust will pay MFSC an account maintenance fee of no more than $9.00 and a dividend services fee of $0.75 per reinvestment and will reimburse MFSC for reasonable out-of-pocket expenses. (4) Portfolio Securities Purchases and sales of investments, other than purchased option transactions and short-term obligations, were as follows: PURCHASES SALES ------------------------------------------------------------------------------ U.S. government securities $116,915,891 $123,769,213 ------------ ------------ Investments (non-U.S. government securities) $ 55,526,268 $ 72,033,213 ------------ ------------ The cost and unrealized appreciation and depreciation in the value of the investments owned by the Trust, as computed on a federal income tax basis, are as follows: Aggregate cost $920,655,396 ------------ Gross unrealized depreciation $(30,772,320) Gross unrealized appreciation 17,718,562 ------------ Net unrealized depreciation $(13,053,758) ============ (5) Shares of Beneficial Interest The trust's Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. The Trustees have authorized 202,648,016 full and fractional shares of beneficial interest. Transactions in trust shares were as follows: SIX MONTHS ENDED YEAR ENDED APRIL 30, 2001 OCTOBER 31, 2000 ---------------------- ---------------------- SHARES AMOUNT SHARES AMOUNT ----------------------------------------------------------------------------- Treasury shares acquired 1,106,500 $7,248,639 6,476,000 $40,697,949 ========= ========== ========= =========== In accordance with the provisions of the trust's prospectus, 1,106,500 shares of beneficial interest were purchased by the trust during period ended April 30, 2001, at an average price per share of $6.55 and a weighted average discount of 8.64% per share. The trust repurchased 6,476,000 shares of beneficial interest during the year ended October 31, 2000, at an average price per shares of $6.28 and a weighted average discount of 11.46% per share. (6) Line of Credit The trust and other affiliated funds participate in a $1.225 billion unsecured line of credit provided by a syndication of banks under a line of credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the bank's base rate. A commitment fee of $6,510 which is based on the average daily unused portion of the line of credit is included in miscellaneous expense. The trust had no significant borrowings during the period. (7) Financial Instruments The trust trades financial instruments with off-balance-sheet risk in the normal course of its investing activities in order to manage exposure to market risks such as interest rates and foreign currency exchange rates. These financial instruments include written options, forward foreign currency exchange contracts, swap agreements, and futures contracts. The notional or contractual amounts of these instruments represent the investment the trust has in particular classes of financial instruments and does not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered.
