Manning] As the firm's new Chief Executive Officer, I want to thank you for your continued trust in MFS and tell you about the series of actions we have taken since our recent settlements with the regulators. These actions are designed to enhance the governance structure of the MFS funds, tighten our business practices, and strengthen the management team at MFS. In early February, Robert Pozen joined MFS as non-executive Chairman. A seasoned veteran of the mutual fund industry, Bob has held prior positions as President of Fidelity Management & Research Company, as Associate General Counsel of the Securities and Exchange Commission, and as a visiting professor at Harvard Law School. In an effort to develop and implement policies that we believe will set a new standard in regulatory compliance, MFS has hired two new senior executives. Jeffrey Carp is joining us as General Counsel with responsibility for all of our legal affairs. Previously he was a senior partner with the law firm of Hale and Dorr LLP. Also joining MFS in the new position of Executive Vice President of Regulatory Affairs is Maria Dwyer, who returned to the firm after serving as a senior executive at Fidelity. At MFS, Maria is in charge of compliance, internal audit, and fund treasury. In the area of governance, we have taken steps to enhance the independence of our funds' boards of trustees to better protect the interests of shareholders. We have independent board chairs and at least 75% of the trustees are independent. The trustees will appoint not only their own counsel but also an independent compliance officer. This officer will assist the boards and their committees in monitoring the MFS funds' compliance with federal and state regulations. In February, MFS reached agreements with federal and state regulators to settle their administrative proceedings against the firm and two senior executives in connection with market timing and related issues. Under the terms of the settlements, we agreed to pay $225 million to compensate affected retail fund shareholders. The $225 million will be distributed in accordance with a distribution plan developed by an independent consultant. We have further agreed with state regulators to reduce management fees on certain funds we advise by approximately $25 million annually over the next five years and to pay an administrative fine of $1 million, which will be used for the purpose of investor education. We have introduced a set of policies designed to protect the MFS funds and MFS fund shareholders from market timing abuses. By July, all MFS retail funds, except money market funds, will have a 2% redemption fee on short-term trades. Our global, international, high-yield, mid- and small-cap funds will impose the 2% fee on redemptions or exchanges of fund shares made within 30 calendar days of a share purchase. For all other MFS funds, except money market funds, the 2% fee will be imposed on redemptions or exchanges made within 5 business days of a share purchase. See the fund prospectus for more information. We continue to use fair value pricing, a strategy that minimizes the potential for investors to take advantage of "stale" prices. These can occur, as one example, when funds own foreign securities whose prices close on overseas exchanges in different time zones. At the same time, we enhanced our monitoring of excessive trading. We did so by increasing our staff and updating our computer systems to improve our ability to detect excessive trading in our funds. Finally, we are supporting industry efforts to establish a "hard" 4 p.m. close on all trading, which would prevent the possibility of late trading. In March, MFS reached a second settlement with the SEC under an administrative proceeding resolving the SEC's investigation into how we disclosed brokerage allocation practices in connection with fund sales. According to the settlement order, we did not effectively disclose the potential conflict of interest that may arise from these arrangements. Under the terms of the settlement, MFS has agreed to pay one dollar in disgorgement and $50 million in penalty to MFS fund shareholders. The settlement noted that MFS had policies in place designed to obtain best execution of all trades of securities within MFS portfolios. This past November, MFS eliminated the above mentioned practice of directing brokerage commissions to certain firms in recognition of fund sales. Additionally, we announced in March that we would ban the use of soft dollars to acquire third-party securities research and market data. Soft dollars are permitted under federal securities laws. In fact, it is a common industry practice to use a portion of the brokerage commissions to pay for certain research and execution products and services that are provided to asset managers. MFS will now pay cash out of its own pocket for third-party research and market data. MFS continues to be financially strong, with more than U.S. $140 billion (as of 12/31/03) in assets under management, which continued to be stable during the first quarter of 2004. We also have the full support of our parent company, Sun Life Financial, an internationally diversified financial services firm that manages more than U.S. $269 billion (as of 12/31/03). We chose to settle these two proceedings with the SEC so we could concentrate on serving our fund shareholders. As Chief Investment Officer, my focus is on ensuring that our portfolio teams work closely together and take full advantage of all the resources available to them to deliver the best possible investment performance. As the inventor of the open-end mutual fund in America in 1924, MFS has a strong tradition and culture of innovation. By strengthening our business and governance practices, we believe we have an unprecedented opportunity to set a new standard in the mutual fund industry. As I look ahead, I do so with confidence. The collaboration among MFS employees, many of whom have worked at the firm for their entire careers, continues as we remain singularly dedicated to our clients. It has been our sincere privilege to serve you, and we thank you for the confidence that you have shown in MFS. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer MFS Investment Management(R) March 15, 2004 Note to Shareholders: On February 6, 2004, Jeffrey L. Shames retired as Chairman of MFS. Robert Pozen was named as non-executive Chairman. Also, on February 6, 2004, Robert J. Manning was appointed Chief Executive Officer, President, and Chief Investment Officer. The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed. - ------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - ------------------------------------------------------------------------------- THE MFS(R) DIFFERENCE For 80 years MFS has been offering investors clear paths to pursuing specific investment objectives. Today, millions of individuals and thousands of institutions all over the world look to MFS to manage their assets with insight and care. Our success, we believe, has to do with the fact that we see investors as people with plans, not just dollars to invest. When you invest with MFS, you invest with a company dedicated to helping you realize your long-term financial goals. INVESTORS CHOOSE MFS FOR OUR o global asset management expertise across all asset classes o time-tested money management process for pursuing consistent results o full spectrum of investment products backed by MFS Original Research(R) o resources and services that match real-life needs TURNING INFORMATION INTO OPPORTUNITY Sound investments begin with sound information. MFS has been doing its own research and analyzing findings in-house for decades. The process we use to uncover opportunity is called MFS Original Research(R). MFS ORIGINAL RESEARCH INVOLVES: o meeting with the management of 3,000 companies each year to assess their business plans and the managers' ability to execute those plans o making onsite visits to more than 2,000 companies annually to gain first-hand knowledge of their operations and products o analyzing financial statements and balance sheets o talking extensively with companies' customers and competitors o developing our own proprietary estimates of companies' earnings - ------------------------------------------------------------------------------- MANAGEMENT REVIEW - ------------------------------------------------------------------------------- MARKET ENVIRONMENT For most of the reporting period, markets around the world were lifted by a stronger economic environment. Worldwide monetary policies continued to be conducive to growth as central banks generally kept interest rates low. Capital spending increases in the United States, positive consumer and business confidence throughout the world, and optimism for increased consumer spending in Europe kept markets moving upward until the end of February 2004 when the markets retreated somewhat from their highs. - ----------------------------------------------- TOP 5 SECTOR WEIGHTINGS AS OF 2/29/04 FINANCIAL SERVICES 24.6% - ----------------------------------------------- UTILITIES & COMMUNICATIONS 13.1% - ----------------------------------------------- HEALTH CARE 9.5% - ----------------------------------------------- LEISURE 8.0% - ----------------------------------------------- ENERGY 7.5% - ----------------------------------------------- The portfolio is actively managed, and current holdings may be different. - ----------------------------------------------- DETRACTORS FROM PERFORMANCE The fund underperformed its benchmark, the MSCI (Morgan Stanley Capital International) EAFE (Europe Australasia Far East) Index, over the period. Stock selection in the technology, leisure, and utilities and communications sectors detracted from relative returns. In the technology sector, we had invested a portion of fund assets in companies that supplied parts used in consumer electronics. Although this subset of the technology sector had done well early in 2003, we saw signs of waning investor appeal in the latter part of 2003 and early 2004. Alps Electric, a Japanese electronic component manufacturer, lowered its fourth quarter 2003 earnings estimates because, in our view, of adverse currency changes between the Japanese yen and the U.S. dollar. The company also indicated that its research and development costs were higher than it had expected. The fund sold this stock during the period. The fund owned a number of stocks in the leisure group that underperformed the broad market, particularly media companies whose income partly depends on advertising revenues. We had believed that the recovering global economy would be accompanied by an increase in advertising revenues. However, those gains have been slow to materialize, and many of our media stocks underperformed the overall market. Another leisure stock, Tamron, a Japanese company that makes lenses for digital still cameras, also detracted from results. Although the cameras sold well in 2003, we have observed increased investor skepticism about potential returns from the product group in 2004. That skepticism, we believe, negatively affected Tamron's stock price. Some of the stocks the fund owned in the utilities and communications sector provided disappointing returns for the period. Japanese company Vodafone Holdings and Korean firm Hanaro Telecom were the two largest detractors in the group. Vodafone Holdings, which was sold from the portfolio by period end, missed its third-quarter earnings estimate and announced in December 2003 that it would again delay its 3G (third generation) wireless introduction. Hanaro Telecom used the fourth quarter of 2003 to clean out problems in its balance sheet related to equipment write-offs and financing costs. In addition, a number of individual but significant stakeholders in the company sold their shares and those sales depressed the company's stock price. Canadian brewer Molson also had a negative impact on relative fund returns. Molson's stock price sank as a result of fierce competition in Brazil and business disruptions at its distributor in Sao Paulo. The fund sold its position in Molson by the end of the period. Throughout the period, the fund maintained a small allocation to short-term cash equivalent securities, which are used to purchase new securities and to provide liquidity. When the stock market rose, that cash position detracted from fund performance relative to the MSCI EAFE Index, which holds no cash position. CONTRIBUTORS TO PERFORMANCE Stock selection in both the financial services and basic materials sectors aided relative performance. Although the fund was underweighted in financial services, which was a negative factor, a number of companies in the group generated strong returns. Standouts included German real-estate finance company Hypo Real Estate NPV and Irish small-business lender Anglo Irish Bank. Hypo Real Estate, a real-estate spin-off from HypoVereinsbank, benefited from a more positive German economic environment and a strong balance sheet. An improved economic environment, and participation in the small-business lending market, helped Anglo Irish Bank. Performance results from the fund's basic materials holdings exceeded broad market returns because of increased demand from China and the global market recovery helped fuel results for commodities such as metals, chemicals, and industrial gases. After years of sluggish growth and underinvestment in developing additional capacity, the group rebounded from depressed prices. Although the utilities and communications sector detracted from fund returns as noted earlier, the fund benefited from owning the Indian telecommunications company Bharti Tele-Ventures while avoiding NTT DoCoMo, the wireless telecommunications arm of Japanese communications company Nippon Telegraph and Telephone. We believe that Bharti's stock price rose because of growth in its subscriber base, the growth potential of its local markets, and good results reported for the second and third quarters of 2003. Not owning NTT DoCoMo stock contributed to the fund's relative returns because the company's stock price declined during the period. Nippon Electric Glass Company was the fund's top individual stock contributor. The company's excess inventory of CRTs (cathode ray tubes) early in the period was absorbed by the marketplace in mid-2003 and the company's stock rebounded by late summer. Nippon's stock price received a further lift when its liquid crystal display business took off in the latter part of 2003. The fund sold this stock when it reached our performance objective.

INDEX DEFINITION MORGAN STANLEY CAPITAL INTERNATIONAL (MSCI) EAFE (EUROPE, AUSTRALASIA, FAR EAST) INDEX - a commonly used measure of the international stock market. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Class A and 529A results, including sales charge, reflects the deduction of the maximum 5.75% sales charge. Class B and 529B results, including sales charge, reflects the deduction of the applicable contingent deferred sales charge (CDSC), which declines over six years from 4% to 0%. Class C and 529C results, including sales charge, redeemed within one year from the end of the calendar month of purchase reflects the deduction of the 1% CDSC. Class I shares have no sales charges and are available only to certain investors. Class R1 and R2 shares have no sales charges and are available only to certain retirement plans. Class 529A, 529B, and 529C shares are only available in conjunction with qualified tuition programs, such as the MFS 529 Savings Plan. The fund will charge a 2% redemption fee on proceeds from Class A, Class C, and Class I shares redeemed (either by redeeming or exchanging) within 30 days of acquiring (either by purchasing or exchanging) fund shares. The redemption fee is expected to apply to Class B shares approximately the end of the third quarter of 2004. See the prospectus for complete details. Performance for share classes offered after class A shares includes the performance of the fund's class A shares for periods prior to their offering. Blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the initial share class, and lower performance for share classes with lower operating expenses than the initial share class. 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. KEY RISK CONSIDERATIONS Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. The portfolio may invest a substantial amount of its assets in issuers located in a limited number of countries and therefore is susceptible to adverse economic, political or regulatory developments affecting those countries. These risks may increase share price volatility. Please see the prospectus for further information regarding these and other risk considerations. This report is prepared for the general information of shareholders. It is authorized for distribution to prospective investors only when preceded or accompanied by a current prospectus. - ---------------------------------------------------------------------------------------------- PORTFOLIO OF INVESTMENTS (unaudited) - 2/29/04 - ---------------------------------------------------------------------------------------------- The Portfolio of Investments is a complete list of all securities owned by your fund.

See notes to financial statements. - ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (unaudited) - ------------------------------------------------------------------------------- (1) BUSINESS AND ORGANIZATION MFS Research International Fund (the fund) is a diversified series of MFS Series Trust I (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. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 fund 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 - The fund uses independent pricing services approved by the Board of Trustees wherever possible to value its portfolio securities. Portfolio securities are valued at current market prices where current market prices are readily available, or the fund may fair value portfolio securities under the direction of the Board of Trustees when a determination is made that current market prices are not readily available. Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Equity securities for which it is determined that current market prices are not readily available will be fair valued under the direction of the Board of Trustees. The fund may also fair value foreign equity securities in cases where closing market prices are not readily available or are deemed not reflective of readily available market prices. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the fund calculates its net asset value (generally, the close of the New York Stock Exchange) that may impact the value of securities traded in these foreign markets. In these cases, the fund may utilize information from an external vendor or other sources to adjust closing market prices of foreign equity securities to reflect what it believes to be the fair value of the securities as of the fund's valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes market value as determined by the Board of Trustees. 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. REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with institutions that the fund's investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The fund requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. The fund 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 fund under each such repurchase agreement. The fund, 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 - 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. SECURITY LOANS - State Street Bank and Trust Company ("State Street") as lending agent, may loan the securities of the fund to certain qualified institutions (the "Borrowers") approved by the fund. 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 fund with indemnification against Borrower default. The fund bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or 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 fund and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the fund 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. SHORT TERM FEES - The fund charges a 2% redemption fee (which is retained by the fund) on proceeds from shares redeemed or exchanged within 30 days following the acquisition (either by purchase or exchange) of certain fund shares made on or after December 8, 2003. These fees are accounted for as an addition to paid-in-capital. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with accounting principles generally accepted in the United States of America. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. During the six months ended February 29, 2004, the fund's custodian fees were reduced by $3,488 under this arrangement. The fund has entered into a commission recapture agreement, under which certain brokers will credit the fund a portion of the commissions generated, to offset certain expenses of the fund. For six months ended February 29, 2004, the fund's miscellaneous expenses were reduced by $2,788 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The fund'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 fund 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. Common types of book and tax differences that could occur include differences in accounting for currency transactions and capital losses. The fund paid no distributions for the years ended August 31, 2002 and August 31, 2003. As of August 31, 2003, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $1,045,910 - ------------------------------------------------------------------------- Capital loss carryforward (107,978,064) - ------------------------------------------------------------------------- Unrealized appreciation 45,115,621 - ------------------------------------------------------------------------- Other temporary differences (74,296) - ------------------------------------------------------------------------- For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration. EXPIRATION DATE August 31, 2009 $(4,216,806) - ------------------------------------------------------------------------ August 31, 2010 (58,123,654) - ------------------------------------------------------------------------ August 31, 2011 (45,637,604) - ------------------------------------------------------------------------ Total $(107,978,064) - ------------------------------------------------------------------------ MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple classes of shares, which differ in their respective distribution and service fees. All shareholders bear the common expenses of the fund based on daily net assets of each class, without distinction between share classes. 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 529B shares will convert to Class A and Class 529A shares, respectively approximately eight years after purchase. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. Effective January 1, 2004, the management fee is computed daily and paid monthly at the following annual rates: First $1.0 billion of average net assets 0.90% ---------------------------------------------------------- Next $1.0 billion of average net assets 0.80% ---------------------------------------------------------- Average net assets in excess of $2.0 billion 0.70% ---------------------------------------------------------- Prior to January 1, 2004, the management fee was computed daily and paid monthly at an annual rate of 1.00% of the fund's average daily net assets. Management fees incurred for the six months ended February 29, 2004 were 0.96% of average daily net assets on an annualized basis. MFS has contractually agreed, subject to reimbursement, to bear a portion of the fund's "Other Expenses", which are defined as the fund's operating expenses, exclusive of management, distribution and service, and certain other fees and expenses, such that Other Expenses do not exceed 0.40% annually. This arrangement is effected by MFS bearing all of the fund's Other Expenses during the fund's fiscal year and the fund paying MFS an expense reimbursement fee not greater than 0.40% of average daily net assets for Class A, Class B, Class C, Class I, and Class R1 and not greater than 0.65% of average daily net assets for Class 529A, Class 529B, Class 529C, and Class R2. To the extent that the expense reimbursement fee exceeds the fund's actual expenses, the excess will be applied to unreimbursed amounts paid by MFS under the currrent agreement. This agreement will terminate on the earlier of July 31, 2005 or such date as all expenses previously borne by MFS under the current agreement have been paid by the fund. At February 29, 2004, aggregate unreimbursed expenses amounted to $1,272,138. The fund pays compensation to the Independent Trustees ("Trustees") in the form of both a retainer and attendance fees, and pays no compensation directly to its Trustees who are officers of the investment adviser, or to officers of the fund, all of whom receive remuneration for their services to the fund from MFS. Certain officers and Trustees of the fund are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The fund has an unfunded, defined benefit plan for retired Trustees and an unfunded retirement benefit deferral plan for current Trustees. Included in Trustees" compensation is a net increase of $11,281 as a result of the change in the fund's pension liability for current Trustees and a pension expense of $309 for retired Trustees for the six months ended February 29, 2004. ADMINISTRATOR - The fund has an administrative services agreement with MFS to provide the fund with certain financial, legal, shareholder communications, compliance, and other administrative services. As a partial reimbursement for the cost of providing these services, the fund pays MFS an administrative fee up to the following annual percentage rates of the fund'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% ---------------------------------------------------------- In addition to the administrative services provided by MFS to the fund as described above, MFS is responsible for providing certain administrative services with respect to class R2 shares. These services include various administrative, recordkeeping, and communication/educational services with respect to the retirement plans which invest in class R2 shares, and may be provided directly by MFS or by a third party. The fund pays an annual 0.25% administrative service fee solely from the assets of class R2 shares to MFS for the provision of these services. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, as distributor, received $45,505 and $310 for the six months ended February 29, 2004, as its portion of the sales charge on sales of Class A and Class 529A shares of the fund, respectively. The Trustees have adopted a distribution plan for Class A, Class B, Class C, Class R1, Class R2, Class 529A, Class 529B and Class 529C shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as follows: The fund's distribution plan provides that the fund will pay MFD an annual percentage of its average daily net assets attributable to certain share classes in order that MFD may pay expenses on behalf of the fund related to the distribution and servicing of its shares. These expenses include a service fee paid to each securities dealer that enters into a sales agreement with MFD based on the average daily net assets of accounts attributable to such dealers. These fees are calculated based on each class" average daily net assets. The maximum distribution and service fees for each class of shares are as follows: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Distribution Fee 0.10% 0.75% 0.75% 0.25% 0.25% - ---------------------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% 0.25% 0.25% - ---------------------------------------------------------------------------------------------------------------- Total Distribution Plan 0.35% 1.00% 1.00% 0.50% 0.50% - ---------------------------------------------------------------------------------------------------------------- CLASS 529A CLASS 529B CLASS 529C Distribution Fee 0.25% 0.75% 0.75% - ---------------------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% - ---------------------------------------------------------------------------------------------------------------- Total Distribution Plan 0.50% 1.00% 1.00% - ---------------------------------------------------------------------------------------------------------------- MFD retains the service fee for accounts not attributable to a securities dealer, which for the six months ended February 29, 2004 amounted to: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Service Fee Retained by MFD $7,456 $291 $150 $-- $-- - ---------------------------------------------------------------------------------------------------------------- CLASS 529A CLASS 529B CLASS 529C Service Fee Retained by MFD $49 $6 $24 - ---------------------------------------------------------------------------------------------------------------- Fees incurred under the distribution plan during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Effective Annual Percentage Rates 0.35% 1.00% 1.00% 0.50% 0.50% - -------------------------------------------------------------------------------- CLASS 529A CLASS 529B CLASS 529C Effective Annual Percentage Rates 0.35% 1.00% 1.00% - -------------------------------------------------------------------------------- Payment of the 0.15% per annum portion of the Class 529A distribution fee that is not currently being charged will be implemented on such a date as the Trustees of the Trust may determine. Certain Class A, Class C and Class 529C shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within, for class A shares, 12 months following the purchase, and, for class C and 529C shares, the first year from the end of the calendar month of purchase.

(6) LINE OF CREDIT The fund and other affiliated funds participate in an $800 million 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 plus 0.50%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the fund for the six months ended February 29, 2004, was $3,045. The fund had no borrowings during the period. (7) LEGAL PROCEEDINGS On March 31, 2004, MFS settled an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. Under the terms of the settlement, in which MFS neither admitted nor denied any wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50 million in penalty to certain MFS funds, pursuant to a plan to be approved by an independent distribution consultant. The agreement with the SEC is reflected in an order of the SEC. The settlement order states that MFS failed to adequately disclose to the Boards of Trustees and to shareholders of the MFS funds the specifics of its preferred arrangements with certain brokerage firms selling MFS fund shares. The settlement order states that MFS had in place policies designed to obtain best execution of all fund trades. As part of the settlement, MFS also agreed to retain an independent compliance consultant to review the completeness of its disclosure to fund trustees and to fund shareholders of strategic alliances between MFS or its affiliates and broker-dealers and other financial advisers who support the sale of fund shares. The brokerage allocation practices which were the subject of this proceeding were discontinued by MFS in November 2003. In addition, in February, 2004, MFS reached agreement with the Securities and Exchange Commission ("SEC"), the New York Attorney General ("NYAG") and the Bureau of Securities Regulation of the State of New Hampshire ("NH") to settle administrative proceedings alleging false and misleading information in certain MFS fund prospectuses regarding market timing and related matters (the "February Settlements"). These regulators alleged that prospectus language for certain MFS funds was false and misleading because, although the prospectuses for those funds in the regulators' view indicated that the funds prohibited market timing, MFS did not limit trading activity in 11 domestic large cap stock, high grade bond and money market funds. MFS' former Chief Executive Officer, John W. Ballen, and former President, Kevin R. Parke, have also reached agreement with the SEC (Messrs. Ballen and Parke resigned their director and officer positions with MFS on February 13, 2004). Under the terms of the February Settlements, MFS and the executives neither admit nor deny wrongdoing. Under the terms of the February Settlements, a $225 million pool has been established for distribution to shareholders in certain of the MFS funds offered to retail investors ("Retail Funds"), which has been funded by MFS and of which $50 million is characterized as a penalty. This pool will be distributed in accordance with a methodology developed by an independent distribution consultant in consultation with MFS and the Boards of Trustees of the Retail Funds, and acceptable to the SEC. MFS has further agreed with the NYAG to reduce its management fees in the aggregate amount of approximately $25 million annually over the next five years, and not to increase certain management fees during this period. MFS has also paid an administrative fine to NH in the amount of $1 million, which will be used for investor education purposes (NH will retain $250,000 and $750,000 will be contributed to the North American Securities Administrators Association's Investor Protection Trust). In addition, MFS and the Retail Funds will adopt certain governance changes. Messrs. Ballen and Parke have agreed to temporary suspensions from association with any registered investment company or investment adviser, will pay approximately $315,000 each to the SEC, and resigned their positions as trustees of all MFS funds, and Mr. Ballen resigned his position as President of all MFS funds, effective February 6, 2004. Messrs. Ballen and Parke will not be returning to MFS or the MFS funds after their suspensions. Since December 2003, MFS, Sun Life Financial Inc., various MFS funds, the Trustees of these MFS funds, and certain officers of MFS have been named as defendants in multiple lawsuits filed in federal and state courts. The lawsuits variously have been commenced as class actions or individual actions on behalf of investors who purchased, held or redeemed shares of the funds during specified periods, as class actions on behalf of participants in certain retirement plan accounts, or as derivative actions on behalf of the MFS funds. The lawsuits generally allege that some or all of the defendants (i) permitted or acquiesced in market timing and/or late trading in some of the MFS funds, inadequately disclosed MFS' internal policies concerning market timing and such matters, and received excessive compensation as fiduciaries to the MFS fund, or (ii) permitted or acquiesced in the improper use of fund assets by MFS to support the distribution of fund shares and inadequately disclosed MFS' use of fund assets in this manner. The actions assert that some or all of the defendants violated the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of 1940 and the Investment Advisers Act of 1940, the Employee Retirement Income Security Act of 1974, as well as fiduciary duties and other violations of common law. The lawsuits seek unspecified compensatory damages. Insofar as any of the actions is appropriately brought derivatively on behalf of any of the MFS funds, any recovery will inure to the benefit of the funds. The defendants are reviewing the allegations of the multiple complaints and will respond appropriately. Additional lawsuits based on similar allegations may be filed in the future. Any potential resolution of these matters may include, but not be limited to, judgments or settlements for damages against MFS, the MFS funds, or any other named defendant. As noted above, as part of the regulatory settlements, MFS has established a restitution pool in the amount of $225 million to compensate certain shareholders of the Retail Funds for damages that they allegedly sustained as a result of market timing or late trading in certain of the funds, and will pay $50 million to compensate certain MFS funds based upon the amount of brokerage commissions allocated in recognition of fund sales. It is not clear whether these amounts will be sufficient to compensate shareholders for all of the damage they allegedly sustained, whether certain shareholders or putative class members may have additional claims to compensation, or whether the damages that may be awarded in any of the actions will exceed these amounts. In the event the MFS funds incur any losses, costs or expenses in connection with such lawsuits, the Boards of Trustees of the affected funds may pursue claims on behalf of such funds against any party that may have liability to the funds in respect thereof. Review of these matters by the independent Trustees of the MFS funds and their counsel is continuing. There can be no assurance that these regulatory actions and lawsuits, or the adverse publicity associated with these developments will not result in increased fund redemptions, reduced sales of fund shares, or other adverse consequences to the funds. - -------------------------------------------------------------------------------------------------------------- TRUSTEES AND OFFICERS - -------------------------------------------------------------------------------------------------------------- The following tables present certain information regarding the Trustees and officers of MFS Series Trust I, of which the fund is a series, including their principal occupations, which, unless specific dates are shown, are of more than five years' duration, although the titles may not have been the same throughout.

Manning] As the firm's new Chief Executive Officer, I want to thank you for your continued trust in MFS and tell you about the series of actions we have taken since our recent settlements with the regulators. These actions are designed to enhance the governance structure of the MFS funds, tighten our business practices, and strengthen the management team at MFS. In early February, Robert Pozen joined MFS as non-executive Chairman. A seasoned veteran of the mutual fund industry, Bob has held prior positions as President of Fidelity Management & Research Company, as Associate General Counsel of the Securities and Exchange Commission, and as a visiting professor at Harvard Law School. In an effort to develop and implement policies that we believe will set a new standard in regulatory compliance, MFS has hired two new senior executives. Jeffrey Carp is joining us as General Counsel with responsibility for all of our legal affairs. Previously he was a senior partner with the law firm of Hale and Dorr LLP. Also joining MFS in the new position of Executive Vice President of Regulatory Affairs is Maria Dwyer, who returned to the firm after serving as a senior executive at Fidelity. At MFS, Maria is in charge of compliance, internal audit, and fund treasury. In the area of governance, we have taken steps to enhance the independence of our funds' boards of trustees to better protect the interests of shareholders. We have independent board chairs and at least 75% of the trustees are independent. The trustees will appoint not only their own counsel but also an independent compliance officer. This officer will assist the boards and their committees in monitoring the MFS funds' compliance with federal and state regulations. In February, MFS reached agreements with federal and state regulators to settle their administrative proceedings against the firm and two senior executives in connection with market timing and related issues. Under the terms of the settlements, we agreed to pay $225 million to compensate affected retail fund shareholders. The $225 million will be distributed in accordance with a distribution plan developed by an independent consultant. We have further agreed with state regulators to reduce management fees on certain funds we advise by approximately $25 million annually over the next five years and to pay an administrative fine of $1 million, which will be used for the purpose of investor education. We have introduced a set of policies designed to protect the MFS funds and MFS fund shareholders from market timing abuses. By July, all MFS retail funds, except money market funds, will have a 2% redemption fee on short-term trades. Our global, international, high-yield, mid- and small-cap funds will impose the 2% fee on redemptions or exchanges of fund shares made within 30 calendar days of a share purchase. For all other MFS funds, except money market funds, the 2% fee will be imposed on redemptions or exchanges made within 5 business days of a share purchase. See the fund prospectus for more information. We continue to use fair value pricing, a strategy that minimizes the potential for investors to take advantage of "stale" prices. These can occur, as one example, when funds own foreign securities whose prices close on overseas exchanges in different time zones. At the same time, we enhanced our monitoring of excessive trading. We did so by increasing our staff and updating our computer systems to improve our ability to detect excessive trading in our funds. Finally, we are supporting industry efforts to establish a "hard" 4 p.m. close on all trading, which would prevent the possibility of late trading. In March, MFS reached a second settlement with the SEC under an administrative proceeding resolving the SEC's investigation into how we disclosed brokerage allocation practices in connection with fund sales. According to the settlement order, we did not effectively disclose the potential conflict of interest that may arise from these arrangements. Under the terms of the settlement, MFS has agreed to pay one dollar in disgorgement and $50 million in penalty to MFS fund shareholders. The settlement noted that MFS had policies in place designed to obtain best execution of all trades of securities within MFS portfolios. This past November, MFS eliminated the above mentioned practice of directing brokerage commissions to certain firms in recognition of fund sales. Additionally, we announced in March that we would ban the use of soft dollars to acquire third-party securities research and market data. Soft dollars are permitted under federal securities laws. In fact, it is a common industry practice to use a portion of the brokerage commissions to pay for certain research and execution products and services that are provided to asset managers. MFS will now pay cash out of its own pocket for third-party research and market data. MFS continues to be financially strong, with more than U.S. $140 billion (as of 12/31/03) in assets under management, which continued to be stable during the first quarter of 2004. We also have the full support of our parent company, Sun Life Financial, an internationally diversified financial services firm that manages more than U.S. $269 billion (as of 12/31/03). We chose to settle these two proceedings with the SEC so we could concentrate on serving our fund shareholders. As Chief Investment Officer, my focus is on ensuring that our portfolio teams work closely together and take full advantage of all the resources available to them to deliver the best possible investment performance. As the inventor of the open-end mutual fund in America in 1924, MFS has a strong tradition and culture of innovation. By strengthening our business and governance practices, we believe we have an unprecedented opportunity to set a new standard in the mutual fund industry. As I look ahead, I do so with confidence. The collaboration among MFS employees, many of whom have worked at the firm for their entire careers, continues as we remain singularly dedicated to our clients. It has been our sincere privilege to serve you, and we thank you for the confidence that you have shown in MFS. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer MFS Investment Management(R) March 15, 2004 Note to Shareholders: On February 6, 2004, Jeffrey L. Shames retired as Chairman of MFS. Robert Pozen was named as non-executive Chairman. Also, on February 6, 2004, Robert J. Manning was appointed Chief Executive Officer, President, and Chief Investment Officer. The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed. - -------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - -------------------------------------------------------------------------------- THE MFS(R) DIFFERENCE For 80 years MFS has been offering investors clear paths to pursuing specific investment objectives. Today, millions of individuals and thousands of institutions all over the world look to MFS to manage their assets with insight and care.

When you invest with MFS, you invest with a company dedicated to helping you realize your long-term financial goals. INVESTORS CHOOSE MFS FOR OUR o global asset management expertise across all asset classes o time-tested money management process for pursuing consistent results o full spectrum of investment products backed by MFS Original Research(R) o resources and services that match real-life needs TURNING INFORMATION INTO OPPORTUNITY Sound investments begin with sound information.

MFS ORIGINAL RESEARCH INVOLVES: o meeting with the management of 3,000 companies each year to assess their business plans and the managers' ability to execute those plans o making onsite visits to more than 2,000 companies annually to gain first-hand knowledge of their operations and products o analyzing financial statements and balance sheets o talking extensively with companies' customers and competitors o developing our own proprietary estimates of companies' earnings - -------------------------------------------------------------------------------- MANAGEMENT REVIEW - -------------------------------------------------------------------------------- MARKET ENVIRONMENT The turnaround in global stock markets that began in the spring of 2003 continued for most of the six-month period ended February 29, 2004. The release of increasingly positive economic numbers as the period progressed, particularly with regard to corporate earnings and GDP (gross domestic product) growth, helped drive the equity rally. By late 2003, corporate capital spending, which had been weak for some time, had also begun to accelerate. Another driver of the equity rally, in our view, was the U.S. Federal Reserve Board's decision to leave interest rates at a four-decade low throughout the period. While energy prices rose late in the period, core inflation - excluding volatile food and energy prices - remained very low relative to historical averages. - ----------------------------------------------- TOP 5 SECTOR WEIGHTINGS AS OF 2/29/04 TECHNOLOGY 25.5% - ----------------------------------------------- HEALTH CARE 24.7% - ----------------------------------------------- FINANCIAL SERVICES 9.9% - ----------------------------------------------- RETAILING 9.2% - ----------------------------------------------- LEISURE 8.6% - ----------------------------------------------- The portfolio is actively managed, and current weightings may be different. DETRACTORS FROM PERFORMANCE While fund performance was positive for the six-month period ended February 29, 2004, we did not fully participate in the market's gains; the portfolio underperformed its benchmark, the Russell 1000 Growth Index, and the average large-cap growth fund as reported by Lipper Inc. Relative to our benchmark, transportation was the fund's weakest area over the period. Stock selection as well as an overweighting in the sector hurt results as transportation stocks generally underperformed the broad market. Our key detractors in the sector were a pair of low-cost airlines: Southwest Airlines in the United States and Ryanair in Europe. Issues weighing on Southwest and on the airline group in general included higher fuel prices, soft revenues, and broad security concerns. Ryanair stock declined sharply in late January 2004 when the company warned investors that its low fares could lead to smaller profits in 2004. We subsequently sold our Ryanair position. In the leisure sector, performance likewise suffered due to adverse stock selection and a relative overweighting. Going into the period, we believed our positions in advertising-sensitive broadcasting stocks would benefit from increased ad spending as the U.S. economy recovered. However, advertising spending, particularly in local markets, appeared stagnant during the period. Fund holdings such as media conglomerate Viacom and radio station operator Clear Channel Communications detracted from relative performance. We cut back both positions significantly during the period. Stock selection in the financial services sector also held back relative results. The largest detractor here was student loan agency SLM Corporation (Sallie Mae). In our view, SLM shares' failure to keep pace with the broader market was caused largely by uncertainty concerning the higher education lending reauthorization bill that was pending before Congress. While this has been a less contentious issue in the past, we recognize the potential for heightened political risk during an election year. Over the longer term, however, we believe SLM will likely use its fully integrated product and service platform to continue to increase its competitive advantage. As such, we continued to hold SLM as of period-end, although we did decrease our position during the period. Individual stocks in other sectors that had a meaningful negative impact on results included moderate-priced apparel retailer Kohl's. We believe mediocre merchandising, together with adverse weather in key markets, caused the firm to report weak operating results. We viewed these issues as surmountable and maintained our Kohl's holding over the period. Our underweighted position in pharmaceutical giant Pfizer was also a relative detractor, as its shares gained more than the broad market. The fund's shares in Taiwan Semiconductor, the world's largest dedicated foundry service provider, traded lower and were sold out of the portfolio amid a general semiconductor correction as well as fears of political instability in Taiwan. Meanwhile, our position in digital wireless communications firm QUALCOMM also weighted on relative results. We were underweighted in the stock, which soared over the period, and we also missed some of that strong performance. An overweighting in electric commerce firm InterActiveCorp also held back relative performance as the stock sank during the period. The portfolio's cash position, although it averaged less than 1% of assets over the period, also detracted from relative performance. As with nearly all mutual funds, this portfolio holds some cash to buy new holdings and to cover investor exchanges or redemptions. In a period when equity markets rose sharply, cash hurt performance against our benchmark, the Russell 1000 Growth Index, which has no cash position. CONTRIBUTORS TO PERFORMANCE Relative returns over the period were boosted by individual holdings across a variety of sectors. The strongest single contributor over the period was conglomerate Tyco International, which did well as new management began to turn around the firm's performance. Underweighting retail giant Wal-Mart also aided relative performance as the company's shares significantly underperformed the broad market over the period. While overall stock selection in technology detracted from relative results, a number of technology stocks were among the fund's top performers. These included security software firm Symantec and telecom infrastructure firm Nortel Networks. Valuation concerns led us to underweight semiconductor manufacturer Intel. This helped relative results as the stock, which had soared for much of 2003, retreated in early 2004. Carrying a below-index weight in semiconductor manufacturing equipment company Applied Materials likewise contributed to relative returns as the stock performed poorly. By period-end we had sold our Applied Materials position. The fund's position in pharmaceutical benefits manager (PBM) Caremark Rx helped performance as the stock rose sharply over the period. PBMs are firms that help other companies manage and contain the cost of prescription drug benefits offered to employees. The fund's position in cruise line Carnival also helped results as the stock performed strongly over the period. Not owning pharmaceutical giant Merck also helped relative returns as the firm's stock lost ground over the period. We avoided Merck because we felt its medium-term growth prospects would be limited by patent expirations on key products as well as by a dearth of new drugs in the development pipeline.

INDEX DEFINITION RUSSELL 1000 GROWTH INDEX - measures the performance of large-cap U.S. growth stocks. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Class A results, including sales charge, reflects the deduction of the maximum 5.75% sales charge. Class B results, including sales charge, reflects the deduction of the applicable contingent deferred sales charge (CDSC), which declines over six years from 4% to 0%. Class C results, including sales charge, redeemed within one year from the end of the calendar month of purchase reflects the deduction of the 1% CDSC. Class I shares have no sales charges and are available only to certain investors. Class R1 and R2 shares have no sales charges and are available only to certain retirement plans. Performance for share classes offered after class A shares includes the performance of the fund's class A shares for periods prior to their offering. Blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the initial share class, and lower performance for share classes with lower operating expenses than the initial share class. 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. KEY RISK CONSIDERATIONS Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. Investing in small and/or emerging growth companies is riskier than investing in more-established companies. These risks may increase share price volatility. Please see the prospectus for further information regarding these and other risk considerations. This report is prepared for the general information of shareholders. It is authorized for distribution to prospective investors only when preceded or accompanied by a current prospectus. - -------------------------------------------------------------------------------------------- PORTFOLIO OF INVESTMENTS (unaudited) - 2/29/04 - -------------------------------------------------------------------------------------------- The Portfolio of Investments is a complete list of all securities owned by your fund.

See notes to financial statements. Notes to Financial Statements (unaudited) - continued - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (unaudited) - -------------------------------------------------------------------------------- (1) BUSINESS AND ORGANIZATION MFS Core Growth Fund (the fund) is a diversified series of MFS Series Trust I (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. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 fund 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 - The fund uses independent pricing services approved by the Board of Trustees wherever possible to value its portfolio securities. Portfolio securities are valued at current market prices where current market prices are readily available, or the fund may fair value portfolio securities under the direction of the Board of Trustees when a determination is made that current market prices are not readily available. Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Equity securities for which it is determined that current market prices are not readily available will be fair valued under the direction of the Board of Trustees. The fund may also fair value foreign equity securities in cases where closing market prices are not readily available or are deemed not reflective of readily available market prices. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the fund calculates its net asset value (generally, the close of the New York Stock Exchange) that may impact the value of securities traded in these foreign markets. In these cases, the fund may utilize information from an external vendor or other sources to adjust closing market prices of foreign equity securities to reflect what it believes to be the fair value of the securities as of the fund's valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with institutions that the fund's investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The fund requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. The fund 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 fund under each such repurchase agreement. The fund, 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 - 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. SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as lending agent, may loan the securities of the fund to certain qualified institutions (the "Borrowers") approved by the fund. 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 fund with indemnification against Borrower default. The fund bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or 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 fund and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the fund 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. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. During the six months ended February 29, 2004, the fund's custodian fees were reduced by $2,389 under this arrangement. The fund has entered into a commission recapture agreement, under which certain brokers will credit the fund a portion of the commissions generated, to offset certain expenses of the fund. For the six months ended February 29, 2004, the fund's miscellaneous expenses were reduced by $42,587 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The fund'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 fund 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. Common types of book and tax differences that could occur include differences in accounting for currency transactions and wash sales. The fund paid no distributions for the years ended August 31, 2003 and August 31, 2002. As of August 31, 2003, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Capital loss carryforward $(176,659,316) --------------------------------------------------------- Post-October capital loss deferral (20,420,083) --------------------------------------------------------- Post-October currency loss deferral (57,490) --------------------------------------------------------- Unrealized appreciation 64,564,891 --------------------------------------------------------- Other temporary differences (46,247) --------------------------------------------------------- For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on: EXPIRATION DATE August 31, 2009 $(217,688) --------------------------------------------------------- August 31, 2010 (47,153,586) --------------------------------------------------------- August 31, 2011 (129,288,042) --------------------------------------------------------- Total $(176,659,316) --------------------------------------------------------- MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple classes of shares, which differ in their respective distribution and service fees. All shareholders bear the common expenses of the fund based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. Class B shares will convert to Class A shares approximately eight years after purchase. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund 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 0.75% of the fund's average daily net assets. As part of the settlement agreement with the New York Attorney General concerning market timing and related matters, MFS has agreed to reduce the fund's management fee to 0.65% of average daily net assets for the period March 1, 2004, through February 28, 2009. During this time period, the Board of Trustees will continue to review the appropriateness of all advisory fees in accordance with their oversight responsibilities. After February, 28, 2009, the management fee will be determined in accordance with then existing review policies approved by the Board of Trustees overseeing the fund. The fund pays compensation to the Independent Trustees ("Trustees") in the form of both a retainer and attendance fees, and pays no compensation directly to its Trustees who are officers of the investment adviser, or to officers of the fund, all of whom receive remuneration for their services to the fund from MFS. Certain officers and Trustees of the fund are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The fund has an unfunded defined benefit plan for retired Trustees and an unfunded retirement benefit deferral plan for current Trustees. Included in Trustees' compensation is a net decrease of $10,460 as a result of the change in the fund pension liability for current Trustees and a pension expense of $13,372 for retired Trustees for the six months ended February 29, 2004. ADMINISTRATOR - The fund has an administrative services agreement with MFS to provide the fund with certain financial, legal, shareholder communications, compliance, and other administrative services. As a partial reimbursement for the cost of providing these services, the fund pays MFS an administrative fee up to the following annual percentage rates of the fund'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% --------------------------------------------------------- In addition to the administrative services provided by MFS to the fund as described above, MFS is responsible for providing certain administrative services with respect to Class R2 shares. These services include various administrative, recordkeeping, and communication/educational services with respect to the retirement plans which invest in Class R2 shares, and may be provided directly by MFS or by a third party. The fund pays an annual 0.25% administrative service fee solely from the assets of Class R2 shares to MFS for the provision of these services. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, as distributor, received $53,125 for the six months ended February 29, 2004, as its portion of the sales charge on sales of Class A shares of the fund. The Trustees have adopted a distribution plan for Class A, Class B, Class C, Class R1, and Class R2 shares pursuant to rule 12b-1 of the Investment Company Act of 1940 as follows: The fund's distribution plan provides that the fund will pay MFD an annual percentage of its average daily net assets attributable to certain share classes in order that MFD may pay expenses on behalf of the fund related to the distribution and servicing of its shares. These expenses include a service fee paid to each securities dealer that enters into a sales agreement with MFD based on the average daily net assets of accounts attributable to such dealers. The fees are calculated based on each class' average daily net assets. The maximum distribution and service fees for each class of shares are as follows: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Distribution Fee 0.10% 0.75% 0.75% 0.25% 0.25% - -------------------------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% 0.25% 0.25% - -------------------------------------------------------------------------------------------------------------------- Total Distribution Plan 0.35% 1.00% 1.00% 0.50% 0.50% - -------------------------------------------------------------------------------------------------------------------- MFD retains the service fee for accounts not attributable to a securities dealer, which for the six months ended February 29, 2004, amounted to: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Service Fee Retained by MFD $4,981 $178 $399 $-- $-- - -------------------------------------------------------------------------------------------------------------------- Fees incurred under the distribution plan during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Effective Annual Percentage Rates 0.35% 1.00% 1.00% 0.50% 0.50% - -------------------------------------------------------------------------------------------------------------------- Certain Class A and Class C shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within, for Class A shares, 12 months following the purchase, and, for Class C shares, the first year from the end of the calendar month of purchase. A contingent deferred sales charge is imposed on shareholder redemptions of Class B shares in the event of a shareholder redemption within six years from the end of the calendar month of purchase. MFD receives all contingent deferred sales charges. Contingent deferred sales charges imposed during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C Contingent Deferred Sales Charges Imposed $4,344 $169,453 $8,593 - -------------------------------------------------------------------------------- SHAREHOLDER SERVICING AGENT - Included in shareholder servicing costs is a fee paid to MFSC, a wholly owned subsidiary of MFS, for its services as shareholder servicing agent. The fee is calculated as a percentage of the fund's average daily net assets at an annual rate of 0.11%, which amounted to $424,090 for the six months ended February 29, 2004. Also included in shareholder servicing costs are out-of-pocket expenses, paid to MFSC, which amounted to $138,873 for the six months ended February 29, 2004, as well as other expenses paid to unaffiliated vendors. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $1,246,519,720 and $1,291,276,828, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the fund, as computed on a federal income tax basis, are as follows: Aggregate cost $767,662,061 --------------------------------------------------------- Gross unrealized appreciation $113,811,088 --------------------------------------------------------- Gross unrealized depreciation (53,943,628) --------------------------------------------------------- Net unrealized appreciation $59,867,460 --------------------------------------------------------- (5) SHARES OF BENEFICIAL INTEREST The fund's Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. Transactions in fund shares were as follows: Six months ended Year ended 2/29/04 8/31/03 SHARES AMOUNT SHARES AMOUNT CLASS A SHARES Shares sold 7,536,749 $111,532,569 21,075,431 $274,422,174 - ------------------------------------------------------------------------------------------------------------ Shares reacquired (10,295,227) (152,734,550) (18,249,215) (235,227,052) - ------------------------------------------------------------------------------------------------------------ Net increase (decrease) (2,758,478) $(41,201,981) 2,826,216 $39,195,122 - ------------------------------------------------------------------------------------------------------------ CLASS B SHARES Shares sold 1,199,892 $17,286,082 4,499,700 $57,190,193 - ------------------------------------------------------------------------------------------------------------ Shares reacquired (1,154,714) (16,793,090) (2,266,015) (28,533,992) - ------------------------------------------------------------------------------------------------------------ Net increase 45,178 $492,992 2,233,685 $28,656,201 - ------------------------------------------------------------------------------------------------------------ CLASS C SHARES Shares sold 935,006 $13,447,986 3,430,072 $43,531,150 - ------------------------------------------------------------------------------------------------------------ Shares reacquired (980,110) (14,312,713) (1,903,646) (23,968,254) - ------------------------------------------------------------------------------------------------------------ Net increase (decrease) (45,104) $(864,727) 1,526,426 $19,562,896 - ------------------------------------------------------------------------------------------------------------ CLASS I SHARES Shares sold 16,230 $242,764 55,893 $731,199 - ------------------------------------------------------------------------------------------------------------ Shares reacquired (38,833) (590,600) (89,981) (1,156,127) - ------------------------------------------------------------------------------------------------------------ Net decrease (22,603) $(347,836) (34,088) $(424,928) - ------------------------------------------------------------------------------------------------------------ Six months ended Period ended 2/29/04 8/31/03* SHARES AMOUNT SHARES AMOUNT CLASS R1 SHARES Shares sold 207,020 $3,017,830 215,934 $2,925,853 - ------------------------------------------------------------------------------------------------------------ Shares reacquired (113,550) (1,659,927) (86,274) (1,201,479) - ------------------------------------------------------------------------------------------------------------ Net increase 93,470 $1,357,903 129,660 $1,724,374 - ------------------------------------------------------------------------------------------------------------ Period months ended 2/29/04** SHARES AMOUNT CLASS R2 SHARES Shares sold 343 $5,020 - ------------------------------------------------------------------------- * For the period from the inception of Class R1 shares, December 31, 2002, through August 31, 2003. ** For the period from the inception of Class R2 shares, October 31, 2003, through February 29, 2004. (6) LINE OF CREDIT The fund and other affiliated funds participate in an $800 million 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 plus 0.50%. A commitment fee of $4,174, which is based on the average daily unused portion of the line of credit is included in miscellaneous expense. The fund had no significant borrowings during the six months ended February 29, 2004. (7) LEGAL PROCEEDINGS On March 31, 2004, MFS settled an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. Under the terms of the settlement, in which MFS neither admitted nor denied any wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50 million in penalty to certain MFS funds, pursuant to a plan to be approved by an independent distribution consultant. The agreement with the SEC is reflected in an order of the SEC. The settlement order states that MFS failed to adequately disclose to the Boards of Trustees and to shareholders of the MFS funds the specifics of its preferred arrangements with certain brokerage firms selling MFS fund shares. The settlement order states that MFS had in place policies designed to obtain best execution of all fund trades. As part of the settlement, MFS also agreed to retain an independent compliance consultant to review the completeness of its disclosure to fund trustees and to fund shareholders of strategic alliances between MFS or its affiliates and broker-dealers and other financial advisers who support the sale of fund shares. The brokerage allocation practices which were the subject of this proceeding were discontinued by MFS in November 2003. In addition, in February, 2004, MFS reached agreement with the Securities and Exchange Commission ("SEC"), the New York Attorney General ("NYAG") and the Bureau of Securities Regulation of the State of New Hampshire ("NH") to settle administrative proceedings alleging false and misleading information in certain MFS fund prospectuses regarding market timing and related matters (the "February Settlements"). These regulators alleged that prospectus language for certain MFS funds was false and misleading because, although the prospectuses for those funds in the regulators' view indicated that the funds prohibited market timing, MFS did not limit trading activity in 11 domestic large cap stock, high grade bond and money market funds. MFS' former Chief Executive Officer, John W. Ballen, and former President, Kevin R. Parke, have also reached agreement with the SEC (Messrs. Ballen and Parke resigned their director and officer positions with MFS on February 13, 2004). Under the terms of the February Settlements, MFS and the executives neither admit nor deny wrongdoing. Under the terms of the February Settlements, a $225 million pool has been established for distribution to shareholders in certain of the MFS funds offered to retail investors ("Retail Funds"), which has been funded by MFS and of which $50 million is characterized as a penalty. This pool will be distributed in accordance with a methodology developed by an independent distribution consultant in consultation with MFS and the Boards of Trustees of the Retail Funds, and acceptable to the SEC. MFS has further agreed with the NYAG to reduce its management fees in the aggregate amount of approximately $25 million annually over the next five years, and not to increase certain management fees during this period. MFS has also paid an administrative fine to NH in the amount of $1 million, which will be used for investor education purposes (NH will retain $250,000 and $750,000 will be contributed to the North American Securities Administrators Association's Investor Protection Trust). In addition, MFS and the Retail Funds will adopt certain governance changes. Messrs. Ballen and Parke have agreed to temporary suspensions from association with any registered investment company or investment adviser, will pay approximately $315,000 each to the SEC, and resigned their positions as trustees of all MFS funds, and Mr. Ballen resigned his position as President of all MFS funds, effective February 6, 2004. Messrs. Ballen and Parke will not be returning to MFS or the MFS funds after their suspensions. Since December 2003, MFS, Sun Life Financial Inc., various MFS funds, the Trustees of these MFS funds, and certain officers of MFS have been named as defendants in multiple lawsuits filed in federal and state courts. The lawsuits variously have been commenced as class actions or individual actions on behalf of investors who purchased, held or redeemed shares of the funds during specified periods, as class actions on behalf of participants in certain retirement plan accounts, or as derivative actions on behalf of the MFS funds. The lawsuits generally allege that some or all of the defendants (i) permitted or acquiesced in market timing and/or late trading in some of the MFS funds, inadequately disclosed MFS' internal policies concerning market timing and such matters, and received excessive compensation as fiduciaries to the MFS fund, or (ii) permitted or acquiesced in the improper use of fund assets by MFS to support the distribution of fund shares and inadequately disclosed MFS' use of fund assets in this manner. The actions assert that some or all of the defendants violated the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of 1940 and the Investment Advisers Act of 1940, the Employee Retirement Income Security Act of 1974, as well as fiduciary duties and other violations of common law. The lawsuits seek unspecified compensatory damages. Insofar as any of the actions is appropriately brought derivatively on behalf of any of the MFS funds, any recovery will inure to the benefit of the funds. The defendants are reviewing the allegations of the multiple complaints and will respond appropriately. Additional lawsuits based on similar allegations may be filed in the future. Any potential resolution of these matters may include, but not be limited to, judgments or settlements for damages against MFS, the MFS funds, or any other named defendant. As noted above, as part of the regulatory settlements, MFS has established a restitution pool in the amount of $225 million to compensate certain shareholders of the Retail Funds for damages that they allegedly sustained as a result of market timing or late trading in certain of the funds, and will pay $50 million to compensate certain MFS funds based upon the amount of brokerage commissions allocated in recognition of fund sales. It is not clear whether these amounts will be sufficient to compensate shareholders for all of the damage they allegedly sustained, whether certain shareholders or putative class members may have additional claims to compensation, or whether the damages that may be awarded in any of the actions will exceed these amounts. In the event the MFS funds incur any losses, costs or expenses in connection with such lawsuits, the Boards of Trustees of the affected funds may pursue claims on behalf of such funds against any party that may have liability to the funds in respect thereof. Review of these matters by the independent Trustees of the MFS funds and their counsel is continuing. There can be no assurance that these regulatory actions and lawsuits, or the adverse publicity associated with these developments will not result in increased fund redemptions, reduced sales of fund shares, or other adverse consequences to the funds. - -------------------------------------------------------------------------------------------------------------- TRUSTEES AND OFFICERS - -------------------------------------------------------------------------------------------------------------- The following tables present certain information regarding the Trustees and officers of MFS Series Trust I, of which the fund is a series, including their principal occupations, which, unless specific dates are shown, are of more than five years' duration, although the titles may not have been the same throughout.

Manning] As the firm's new Chief Executive Officer, I want to thank you for your continued trust in MFS and tell you about the series of actions we have taken since our recent settlements with the regulators. These actions are designed to enhance the governance structure of the MFS funds, tighten our business practices, and strengthen the management team at MFS. In early February, Robert Pozen joined MFS as non-executive Chairman. A seasoned veteran of the mutual fund industry, Bob has held prior positions as President of Fidelity Management & Research Company, as Associate General Counsel of the Securities and Exchange Commission, and as a visiting professor at Harvard Law School. In an effort to develop and implement policies that we believe will set a new standard in regulatory compliance, MFS has hired two new senior executives. Jeffrey Carp is joining us as General Counsel with responsibility for all of our legal affairs. Previously he was a senior partner with the law firm of Hale and Dorr LLP. Also joining MFS in the new position of Executive Vice President of Regulatory Affairs is Maria Dwyer, who returned to the firm after serving as a senior executive at Fidelity. At MFS, Maria is in charge of compliance, internal audit, and fund treasury. In the area of governance, we have taken steps to enhance the independence of our funds' boards of trustees to better protect the interests of shareholders. We have independent board chairs and at least 75% of the trustees are independent. The trustees will appoint not only their own counsel but also an independent compliance officer. This officer will assist the boards and their committees in monitoring the MFS funds' compliance with federal and state regulations. In February, MFS reached agreements with federal and state regulators to settle their administrative proceedings against the firm and two senior executives in connection with market timing and related issues. Under the terms of the settlements, we agreed to pay $225 million to compensate affected retail fund shareholders. The $225 million will be distributed in accordance with a distribution plan developed by an independent consultant. We have further agreed with state regulators to reduce management fees on certain funds we advise by approximately $25 million annually over the next five years and to pay an administrative fine of $1 million, which will be used for the purpose of investor education. We have introduced a set of policies designed to protect the MFS funds and MFS fund shareholders from market timing abuses. By July, all MFS retail funds, except money market funds, will have a 2% redemption fee on short-term trades. Our global, international, high-yield, mid- and small-cap funds will impose the 2% fee on redemptions or exchanges of fund shares made within 30 calendar days of a share purchase. For all other MFS funds, except money market funds, the 2% fee will be imposed on redemptions or exchanges made within 5 business days of a share purchase. See the fund prospectus for more information. We continue to use fair value pricing, a strategy that minimizes the potential for investors to take advantage of "stale" prices. These can occur, as one example, when funds own foreign securities whose prices close on overseas exchanges in different time zones. At the same time, we enhanced our monitoring of excessive trading. We did so by increasing our staff and updating our computer systems to improve our ability to detect excessive trading in our funds. Finally, we are supporting industry efforts to establish a "hard" 4 p.m. close on all trading, which would prevent the possibility of late trading. In March, MFS reached a second settlement with the SEC under an administrative proceeding resolving the SEC's investigation into how we disclosed brokerage allocation practices in connection with fund sales. According to the settlement order, we did not effectively disclose the potential conflict of interest that may arise from these arrangements. Under the terms of the settlement, MFS has agreed to pay one dollar in disgorgement and $50 million in penalty to MFS fund shareholders. The settlement noted that MFS had policies in place designed to obtain best execution of all trades of securities within MFS portfolios. This past November, MFS eliminated the above mentioned practice of directing brokerage commissions to certain firms in recognition of fund sales. Additionally, we announced in March that we would ban the use of soft dollars to acquire third-party securities research and market data. Soft dollars are permitted under federal securities laws. In fact, it is a common industry practice to use a portion of the brokerage commissions to pay for certain research and execution products and services that are provided to asset managers. MFS will now pay cash out of its own pocket for third-party research and market data. MFS continues to be financially strong, with more than U.S. $140 billion (as of 12/31/03) in assets under management, which continued to be stable during the first quarter of 2004. We also have the full support of our parent company, Sun Life Financial, an internationally diversified financial services firm that manages more than U.S. $269 billion (as of 12/31/03). We chose to settle these two proceedings with the SEC so we could concentrate on serving our fund shareholders. As Chief Investment Officer, my focus is on ensuring that our portfolio teams work closely together and take full advantage of all the resources available to them to deliver the best possible investment performance. As the inventor of the open-end mutual fund in America in 1924, MFS has a strong tradition and culture of innovation. By strengthening our business and governance practices, we believe we have an unprecedented opportunity to set a new standard in the mutual fund industry. As I look ahead, I do so with confidence. The collaboration among MFS employees, many of whom have worked at the firm for their entire careers, continues as we remain singularly dedicated to our clients. It has been our sincere privilege to serve you, and we thank you for the confidence that you have shown in MFS. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer MFS Investment Management(R) March 15, 2004 Note to Shareholders: On February 6, 2004, Jeffrey L. Shames retired as Chairman of MFS. Robert Pozen was named as non-executive Chairman. Also, on February 6, 2004, Robert J. Manning was appointed Chief Executive Officer, President, and Chief Investment Officer. The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed. - -------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - -------------------------------------------------------------------------------- THE MFS(R) DIFFERENCE For 80 years MFS has been offering investors clear paths to pursuing specific investment objectives.

When you invest with MFS, you invest with a company dedicated to helping you realize your long-term financial goals. INVESTORS CHOOSE MFS FOR OUR o global asset management expertise across all asset classes o time-tested money management process for pursuing consistent results o full spectrum of investment products backed by MFS Original Research(R) o resources and services that match real-life needs TURNING INFORMATION INTO OPPORTUNITY Sound investments begin with sound information.

The release of increasingly positive economic numbers as the period progressed, particularly with regard to corporate earnings and GDP (gross domestic product) growth, helped drive the equity rally. By late 2003, corporate capital spending, which had been weak for some time, had also begun to accelerate. Another driver of the equity rally, in our view, was the U.S. Federal Reserve Board's decision to leave interest rates at a four-decade low throughout the period. While energy prices rose late in the period, core inflation - excluding volatile food and energy prices - remained low relative to historical averages. - ------------------------------------------------ TOP 5 SECTOR WEIGHTINGS 2/29/04 FINANCIAL SERVICES 30.2% - ------------------------------------------------ ENERGY 12.1% - ------------------------------------------------ CONSUMER STAPLES 10.7% - ------------------------------------------------ UTILITIES AND COMMUNICATIONS 10.4% - ------------------------------------------------ HEALTH CARE 8.9% - ------------------------------------------------ The portfolio is actively managed, and current weightings may be different. DETRACTORS FROM PERFORMANCE The fund underperformed its benchmark, the Russell 1000 Value Index (the Russell Index), over the period. Stock selection in the leisure sector was a key detractor from relative returns. Our position in media giant Viacom, the company behind CBS and MTV, fell in price. The firm experienced disappointing growth in advertising revenues, and its Blockbuster Video unit continued to post weak sales growth. Our holding in cable operator Comcast also performed poorly after the firm made a bid to acquire Disney late in the period. The fund did not own Disney stock. The fund's underweighting in financial services stocks, in comparison with the Russell Index, also detracted from relative returns as the sector outperformed the broad market over the period. Stock selection in the sector also detracted modestly from results. Mellon Financial Corp., in particular, held back relative returns. The firm reported lackluster earnings growth for the third quarter of 2003, and its projection of 2004 earnings, in our view, also proved disappointing to investors. The fund's cash position was also a key detractor from relative performance. As with nearly all mutual funds, this fund holds some cash to buy new holdings and to cover shareholder redemptions. In a period when equity markets rose sharply, cash hurt performance against our benchmark, the Russell Index, which has no cash position. Our holding in medical products firm Johnson & Johnson also detracted from relative results. Although the stock increased in price over the period, it underperformed the overall market. Not owning communications equipment provider Lucent Technologies also hurt relative performance. The stock rose sharply over the period as wireless firms increased capital spending on infrastructure. CONTRIBUTORS TO PERFORMANCE Consumer staples and health care holdings were key contributors to the fund's relative returns. In the consumer staples area, both stock selection and an overweighting in the sector proved positive for results as the sector outperformed the broad market for the period. Altria Group (formerly Philip Morris) and Kimberly-Clark generated particularly strong returns. In our view, food and tobacco conglomerate Altria benefited from decreased investor concerns about litigation against the company. Paper products company Kimberly-Clark generated stronger earnings than it had estimated, helped by the impact of a weak U.S. dollar on its international revenues and improvements in some of its key products such as Huggies diapers. Although the fund was overweighted in health care, strong stock selection in the sector also helped relative performance. Not owning pharmaceutical firm Merck added to results as the company's stock, in our view, was adversely affected by potential competition from generic drug companies and a weak pipeline of drugs in development. The fund did have positions in Pfizer and Roche Holdings, and both drug firms outperformed the broad market over the period. Pfizer's performance was helped by a study that showed its cholesterol medication Lipitor was more effective than a leading competitive product. We believe that performance of Swiss pharmaceutical company Roche was helped by the company's strong pipeline of new drugs, relatively low exposure to patent expirations on key products, and opportunities to expand its profit margins. Stocks in other sectors that contributed to performance included FleetBoston Financial, Motorola, and Nortel Networks. FleetBoston's stock price rose sharply when Bank of America announced its $47 billion takeover bid for Fleet. Motorola benefited from its improved projections for cellular handset sales, driven in part by new products and wireless number portability. Nortel's stock, like Lucent's stock mentioned earlier, rose in price as wireless firms increased capital spending on infrastructure. Nortel received a number of new contracts during the period and stated that it expected further gains in its wireless business. We sold our Nortel position when the stock reached our price target.

INDEX DEFINITION RUSSELL 1000 VALUE INDEX - measures the performance of large-cap U.S. value stocks. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Class A and 529A results, including sales charge, reflects the deduction of the maximum 5.75% sales charge. Class B and 529B results, including sales charge, reflects the deduction of the applicable contingent deferred sales charge (CDSC), which declines over six years from 4% to 0%. Class C and 529C results, including sales charge, redeemed within one year from the end of the calendar month of purchase reflects the deduction of the 1% CDSC. Class I shares have no sales charges and are available only to certain investors. Class R1 and R2 shares have no sales charges and are available only to certain retirement plans. Class 529A, 529B, and 529C shares are only available in conjunction with qualified tuition programs, such as the MFS 529 Savings Plan. Performance for share classes offered after class A shares includes the performance of the fund's class A shares for periods prior to their offering. Blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the initial share class, and lower performance for share classes with lower operating expenses than the initial share class. 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.

See notes to financial statements. - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (unaudited) - -------------------------------------------------------------------------------- (1) BUSINESS AND ORGANIZATION MFS Value Fund (the fund) is a diversified series of MFS Series Trust I (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. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 fund 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 - The fund uses independent pricing services approved by the Board of Trustees wherever possible to value its portfolio securities. Portfolio securities are valued at current market prices where current market prices are readily available, or the fund may fair value portfolio securities under the direction of the Board of Trustees when a determination is made that current market prices are not readily available. Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Equity securities for which it is determined that current market prices are not readily available will be fair valued under the direction of the Board of Trustees. The fund may also fair value foreign equity securities in cases where closing market prices are not readily available or are deemed not reflective of readily available market prices. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the fund calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the fund may utilize information from an external vendor or other sources to adjust closing market prices of foreign equity securities to reflect what it believes to be the fair value of the securities as of the fund's valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with institutions that the fund's investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The fund requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. The fund 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 fund under each such repurchase agreement. The fund, 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 - 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. SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as lending agent, may loan the securities of the fund to certain qualified institutions (the "Borrowers") approved by the fund. 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 fund with indemnification against Borrower default. The fund bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund and 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 fund and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the fund 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. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS - The fund 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 fund may enter into forward foreign currency exchange contracts for hedging purposes as well as for non-hedging purposes. For hedging purposes, the fund may enter into contracts to deliver or receive foreign currency it will receive from or require for its normal investment activities. The fund 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 fund may enter into contracts with the intent of changing the relative exposure of the fund'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 discount is amortized or accreted for financial statement purposes in accordance with accounting principles generally accepted in the United States of America. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. During the six months ended February 29, 2004 the fund's custodian fees were reduced by $14,773 under this arrangement. The fund has entered into a commission recapture agreement, under which certain brokers will credit the fund a portion of the commissions generated, to offset certain expenses of the fund. For the six months ended February 29, 2004 the fund's miscellaneous expenses were reduced by $170,261 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The fund'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 fund 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. Common types of book and tax differences that could occur include differences in accounting for currency transactions and real estate investment trusts. The tax character of distributions declared for the years ended August 31, 2003 and August 31, 2002 was as follows: 8/31/03 8/31/02 Distributions declared from: - ------------------------------------------------------------------------------- Ordinary income $43,338,408 $14,275,598 - ------------------------------------------------------------------------------- Long-term capital gain -- 10,609,270 - ------------------------------------------------------------------------------- Total distributions declared $43,338,408 $24,884,868 - ------------------------------------------------------------------------------- As of August 31, 2003 the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $11,237,237 ---------------------------------------------------------- Capital loss carryforward (243,773,787) ---------------------------------------------------------- Post-October capital loss deferral (88,681,815) ---------------------------------------------------------- Unrealized appreciation1 76,356,424 ---------------------------------------------------------- Other temporary differences (13,257) ---------------------------------------------------------- Post-October capital loss deferrals represent losses realized during the current fiscal year, but recognized for tax purposes in the next fiscal year. For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on August 31, 2010 ($49,177,465) and August 31, 2011 ($194,596,322). MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple classes of shares, which differ in their respective distribution and service fees. All shareholders bear the common expenses of the fund based on daily net assets of each class, without distinction between share classes. 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 529B shares will convert to Class A and Class 529A shares, respectively, approximately eight years after purchase. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund 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 0.60% of the fund's average daily net assets. The fund pays compensation to the Independent Trustees ("Trustees") in the form of both a retainer and attendance fees, and pays no compensation directly to its Trustees who are officers of the investment adviser, or to officers of the fund, all of whom receive remuneration for their services to the fund from MFS. Certain officers and Trustees of the fund are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The fund has an unfunded, defined benefit plan for retired Trustees. Included in Trustees' compensation is a pension expense of $651 for retired trustees for the six months ended February 29, 2004. ADMINISTRATOR - The fund has an administrative services agreement with MFS to provide the fund with certain financial, legal, shareholder communications, compliance, and other administrative services. As a partial reimbursement for the cost of providing these services, the fund pays MFS an administrative fee up to the following annual percentage rates of the fund'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% ---------------------------------------------------------- In addition to the administrative services provided by MFS to the fund as described above, MFS is responsible for providing certain administrative services with respect to class R2 shares. These services include various administrative, recordkeeping, and communication/educational services with respect to the retirement plans which invest in class R2 shares, and may be provided directly by MFS or by a third party. The fund pays an annual 0.25% administrative service fee solely from the assets of class R2 shares to MFS for the provision of these services. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, as distributor, received $265,242 and $1,630 for the six months ended February 29, 2004 as its portion of the sales charge on sales of Class A and Class 529A shares of the fund, respectively. The Trustees have adopted a distribution plan for Class A, Class B, Class C, Class R1, Class R2, Class 529A, Class 529B and Class 529C shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as follows: The fund's distribution plan provides that the fund will pay MFD an annual percentage of its average daily net assets attributable to certain share classes in order that MFD may pay expenses on behalf of the fund related to the distribution and servicing of its shares. These expenses include a service fee paid to each securities dealer that enters into a sales agreement with MFD based on the average daily net assets of accounts attributable to such dealers. These fees are calculated based on each class' average daily net assets. The maximum distribution and service fees for each class of shares are as follows: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Distribution Fee 0.10% 0.75% 0.75% 0.25% 0.25% - ----------------------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% 0.25% 0.25% - ----------------------------------------------------------------------------------------------------------------- Total Distribution Plan 0.35% 1.00% 1.00% 0.50% 0.50% - ----------------------------------------------------------------------------------------------------------------- CLASS 529A CLASS 529B CLASS 529C Distribution Fee 0.25% 0.75% 0.75% - ----------------------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% - ----------------------------------------------------------------------------------------------------------------- Total Distribution Plan 0.50% 1.00% 1.00% - ----------------------------------------------------------------------------------------------------------------- MFD retains the service fee for accounts not attributable to a securities dealer, which for the six months ended February 29, 2004, amounted to: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Service Fee Retained by MFD $321,015 $1,816 $1,432 $-- $-- - ----------------------------------------------------------------------------------------------------------------- CLASS 529A CLASS 529B CLASS 529C Service Fee Retained by MFD $347 $6 $24 - ----------------------------------------------------------------------------------------------------------------- Payment of the 0.15% per annum portion of the Class 529A distribution fee that is not currently being charged will be implemented on such a date as the Trustees of the Trust may determine.

A contingent deferred sales charge is imposed on shareholder redemptions of Class B and Class 529B shares in the event of a shareholder redemption within six years from the end of the calendar month of purchase. MFD receives all contingent deferred sales charges. Contingent deferred sales charges imposed during the six months ended February 29, 2004 were as follows: CLASS A CLASS B CLASS C CLASS 529B CLASS 529C Contingent Deferred Sales Charges Imposed $22,536 $1,146,495 $65,618 $60 $-- - -------------------------------------------------------------------------------- The fund has and may from time to time enter into contracts with program managers and other parties which administer the tuition programs through which an investment in the fund's 529 share classes is made. The fund has entered into an agreement with MFD pursuant to which MFD receives an annual fee of up to 0.35% from the fund based solely upon the value of the fund's 529 share classes attributable to tuition programs to which MFD or a third party which contracts with MFD provides administrative services. The current fee has been established at 0.25% annually of average net assets of the fund's 529 share classes attributable to such programs. The fee may only be increased with the approval of the board of trustees that oversees the fund. The services provided by MFD or a third party with which MFD contracts include recordkeeping and tax reporting and account services, as well as services designed to maintain the program's compliance with the Internal Revenue Code and other regulatory requirements. SHAREHOLDER SERVICING AGENT - Included in shareholder servicing costs is a fee paid to MFSC, a wholly owned subsidiary of MFS, for its services as shareholder servicing agent. The fee is calculated as a percentage of the fund's average daily net assets at an annual rate of 0.11%, which amounted to $3,077,106 for the six months ended February 29, 2004. Also included in shareholder servicing costs are out-of-pocket expenses, paid to MFSC, which amounted to $998,887 for the six months ended February 29, 2004, as well as other expenses paid to unaffiliated vendors.

(6) LINE OF CREDIT The fund and other affiliated funds participate in an $800 million 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 plus 0.50%. In addition, a commitment fee, based on the average daily unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the fund for the six months ended February 29, 2004 was $33,623. The fund had no significant borrowings during the period. (7) LEGAL PROCEEDINGS On March 31, 2004, MFS settled an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. Under the terms of the settlement, in which MFS neither admitted nor denied any wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50 million in penalty to certain MFS funds, pursuant to a plan to be approved by an independent distribution consultant. The agreement with the SEC is reflected in an order of the SEC. The settlement order states that MFS failed to adequately disclose to the Boards of Trustees and to shareholders of the MFS funds the specifics of its preferred arrangements with certain brokerage firms selling MFS fund shares. The settlement order states that MFS had in place policies designed to obtain best execution of all fund trades. As part of the settlement, MFS also agreed to retain an independent compliance consultant to review the completeness of its disclosure to fund trustees and to fund shareholders of strategic alliances between MFS or its affiliates and broker-dealers and other financial advisers who support the sale of fund shares. The brokerage allocation practices which were the subject of this proceeding were discontinued by MFS in November 2003. In addition, in February, 2004, MFS reached agreement with the Securities and Exchange Commission ("SEC"), the New York Attorney General ("NYAG") and the Bureau of Securities Regulation of the State of New Hampshire ("NH") to settle administrative proceedings alleging false and misleading information in certain MFS fund prospectuses regarding market timing and related matters (the "February Settlements"). These regulators alleged that prospectus language for certain MFS funds was false and misleading because, although the prospectuses for those funds in the regulators' view indicated that the funds prohibited market timing, MFS did not limit trading activity in 11 domestic large cap stock, high grade bond and money market funds. MFS' former Chief Executive Officer, John W. Ballen, and former President, Kevin R. Parke, have also reached agreement with the SEC (Messrs. Ballen and Parke resigned their director and officer positions with MFS on February 13, 2004). Under the terms of the February Settlements, MFS and the executives neither admit nor deny wrongdoing. Under the terms of the February Settlements, a $225 million pool has been established for distribution to shareholders in certain of the MFS funds offered to retail investors ("Retail Funds"), which has been funded by MFS and of which $50 million is characterized as a penalty. This pool will be distributed in accordance with a methodology developed by an independent distribution consultant in consultation with MFS and the Boards of Trustees of the Retail Funds, and acceptable to the SEC. MFS has further agreed with the NYAG to reduce its management fees in the aggregate amount of approximately $25 million annually over the next five years, and not to increase certain management fees during this period. MFS has also paid an administrative fine to NH in the amount of $1 million, which will be used for investor education purposes (NH will retain $250,000 and $750,000 will be contributed to the North American Securities Administrators Association's Investor Protection Trust). In addition, MFS and the Retail Funds will adopt certain governance changes. Messrs. Ballen and Parke have agreed to temporary suspensions from association with any registered investment company or investment adviser, will pay approximately $315,000 each to the SEC, and resigned their positions as trustees of all MFS funds, and Mr. Ballen resigned his position as President of all MFS funds, effective February 6, 2004. Messrs. Ballen and Parke will not be returning to MFS or the MFS funds after their suspensions. Since December 2003, MFS, Sun Life Financial Inc., various MFS funds, the Trustees of these MFS funds, and certain officers of MFS have been named as defendants in multiple lawsuits filed in federal and state courts. The lawsuits variously have been commenced as class actions or individual actions on behalf of investors who purchased, held or redeemed shares of the funds during specified periods, as class actions on behalf of participants in certain retirement plan accounts, or as derivative actions on behalf of the MFS funds. The lawsuits generally allege that some or all of the defendants (i) permitted or acquiesced in market timing and/or late trading in some of the MFS funds, inadequately disclosed MFS' internal policies concerning market timing and such matters, and received excessive compensation as fiduciaries to the MFS fund, or (ii) permitted or acquiesced in the improper use of fund assets by MFS to support the distribution of fund shares and inadequately disclosed MFS' use of fund assets in this manner. The actions assert that some or all of the defendants violated the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of 1940 and the Investment Advisers Act of 1940, the Employee Retirement Income Security Act of 1974, as well as fiduciary duties and other violations of common law. The lawsuits seek unspecified compensatory damages. Insofar as any of the actions is appropriately brought derivatively on behalf of any of the MFS funds, any recovery will inure to the benefit of the funds. The defendants are reviewing the allegations of the multiple complaints and will respond appropriately. Additional lawsuits based on similar allegations may be filed in the future. Any potential resolution of these matters may include, but not be limited to, judgments or settlements for damages against MFS, the MFS funds, or any other named defendant. As noted above, as part of the regulatory settlements, MFS has established a restitution pool in the amount of $225 million to compensate certain shareholders of the Retail Funds for damages that they allegedly sustained as a result of market timing or late trading in certain of the funds, and will pay $50 million to compensate certain MFS funds based upon the amount of brokerage commissions allocated in recognition of fund sales. It is not clear whether these amounts will be sufficient to compensate shareholders for all of the damage they allegedly sustained, whether certain shareholders or putative class members may have additional claims to compensation, or whether the damages that may be awarded in any of the actions will exceed these amounts. In the event the MFS funds incur any losses, costs or expenses in connection with such lawsuits, the Boards of Trustees of the affected funds may pursue claims on behalf of such funds against any party that may have liability to the funds in respect thereof. Review of these matters by the independent Trustees of the MFS funds and their counsel is continuing. There can be no assurance that these regulatory actions and lawsuits, or the adverse publicity associated with these developments will not result in increased fund redemptions, reduced sales of fund shares, or other adverse consequences to the funds. - -------------------------------------------------------------------------------------------------------------- TRUSTEES AND OFFICERS - -------------------------------------------------------------------------------------------------------------- The following tables present certain information regarding the Trustees and officers of MFS Series Trust I, of which the fund is a series, including their principal occupations, which, unless specific dates are shown, are of more than five years' duration, although the titles may not have been the same throughout.

Manning] As the firm's new Chief Executive Officer, I want to thank you for your continued trust in MFS and tell you about the series of actions we have taken since our recent settlements with the regulators. These actions are designed to enhance the governance structure of the MFS funds, tighten our business practices, and strengthen the management team at MFS. In early February, Robert Pozen joined MFS as non-executive Chairman. A seasoned veteran of the mutual fund industry, Bob has held prior positions as President of Fidelity Management & Research Company, as Associate General Counsel of the Securities and Exchange Commission, and as a visiting professor at Harvard Law School. In an effort to develop and implement policies that we believe will set a new standard in regulatory compliance, MFS has hired two new senior executives. Jeffrey Carp is joining us as General Counsel with responsibility for all of our legal affairs. Previously he was a senior partner with the law firm of Hale and Dorr LLP. Also joining MFS in the new position of Executive Vice President of Regulatory Affairs is Maria Dwyer, who returned to the firm after serving as a senior executive at Fidelity. At MFS, Maria is in charge of compliance, internal audit, and fund treasury. In the area of governance, we have taken steps to enhance the independence of our funds' boards of trustees to better protect the interests of shareholders. We have independent board chairs and at least 75% of the trustees are independent. The trustees will appoint not only their own counsel but also an independent compliance officer. This officer will assist the boards and their committees in monitoring the MFS funds' compliance with federal and state regulations. In February, MFS reached agreements with federal and state regulators to settle their administrative proceedings against the firm and two senior executives in connection with market timing and related issues. Under the terms of the settlements, we agreed to pay $225 million to compensate affected retail fund shareholders. The $225 million will be distributed in accordance with a distribution plan developed by an independent consultant. We have further agreed with state regulators to reduce management fees on certain funds we advise by approximately $25 million annually over the next five years and to pay an administrative fine of $1 million, which will be used for the purpose of investor education. We have introduced a set of policies designed to protect the MFS funds and MFS fund shareholders from market timing abuses. By July, all MFS retail funds, except money market funds, will have a 2% redemption fee on short-term trades. Our global, international, high-yield, mid- and small-cap funds will impose the 2% fee on redemptions or exchanges of fund shares made within 30 calendar days of a share purchase. For all other MFS funds, except money market funds, the 2% fee will be imposed on redemptions or exchanges made within 5 business days of a share purchase. See the fund prospectus for more information. We continue to use fair value pricing, a strategy that minimizes the potential for investors to take advantage of "stale" prices. These can occur, as one example, when funds own foreign securities whose prices close on overseas exchanges in different time zones. At the same time, we enhanced our monitoring of excessive trading. We did so by increasing our staff and updating our computer systems to improve our ability to detect excessive trading in our funds. Finally, we are supporting industry efforts to establish a "hard" 4 p.m. close on all trading, which would prevent the possibility of late trading. In March, MFS reached a second settlement with the SEC under an administrative proceeding resolving the SEC's investigation into how we disclosed brokerage allocation practices in connection with fund sales. According to the settlement order, we did not effectively disclose the potential conflict of interest that may arise from these arrangements. Under the terms of the settlement, MFS has agreed to pay one dollar in disgorgement and $50 million in penalty to MFS fund shareholders. The settlement noted that MFS had policies in place designed to obtain best execution of all trades of securities within MFS portfolios. This past November, MFS eliminated the above mentioned practice of directing brokerage commissions to certain firms in recognition of fund sales. Additionally, we announced in March that we would ban the use of soft dollars to acquire third-party securities research and market data. Soft dollars are permitted under federal securities laws. In fact, it is a common industry practice to use a portion of the brokerage commissions to pay for certain research and execution products and services that are provided to asset managers. MFS will now pay cash out of its own pocket for third-party research and market data. MFS continues to be financially strong, with more than U.S. $140 billion (as of 12/31/03) in assets under management, which continued to be stable during the first quarter of 2004. We also have the full support of our parent company, Sun Life Financial, an internationally diversified financial services firm that manages more than U.S. $269 billion (as of 12/31/03). We chose to settle these two proceedings with the SEC so we could concentrate on serving our fund shareholders. As Chief Investment Officer, my focus is on ensuring that our portfolio teams work closely together and take full advantage of all the resources available to them to deliver the best possible investment performance. As the inventor of the open-end mutual fund in America in 1924, MFS has a strong tradition and culture of innovation. By strengthening our business and governance practices, we believe we have an unprecedented opportunity to set a new standard in the mutual fund industry. As I look ahead, I do so with confidence. The collaboration among MFS employees, many of whom have worked at the firm for their entire careers, continues as we remain singularly dedicated to our clients. It has been our sincere privilege to serve you, and we thank you for the confidence that you have shown in MFS. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer MFS Investment Management(R) March 15, 2004 Note to Shareholders: On February 6, 2004, Jeffrey L. Shames retired as Chairman of MFS. Robert Pozen was named as non-executive Chairman. Also, on February 6, 2004, Robert J. Manning was appointed Chief Executive Officer, President, and Chief Investment Officer. The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed. - ------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - ------------------------------------------------------------------------------- THE MFS(R) DIFFERENCE For 80 years MFS has been offering investors clear paths to pursuing specific investment objectives.

By the end of the six-month period on February 29, 2004, economic conditions appeared to be improving as jobless claims were down. However, energy prices still appeared high to us. In an effort to continue to stabilize prices and stimulate the economy, the Federal Reserve Board (the Fed) maintained the federal funds overnight borrowing rate at 1.00% -- a 46-year low. The Fed maintained in February that it would "...continue to be patient..." before it began to raise rates. CONTINUED SHORT SUPPLY OF COMMERCIAL PAPER Despite signs of growing economic strength, the supply of commercial paper continued to be constrained by cautious corporate spending in our view. Businesses, taking advantage of low absolute yields, issued longer-term debt in place of commercial paper. FUND POSITIONING As of February 29, 2004, over 88% of MFS Cash Reserves Fund was invested in commercial paper with the balance of the portfolio invested in U.S. government discount agency notes and repurchase agreements collateralized by U.S. government agency discount notes. During this reporting period, when interest rates were at historical lows and the Fed continued its accommodative stance, we strategically targeted an average maturity range for the portfolio of 45 to 55 days. COMMITMENT TO QUALITY Regardless of market or economic conditions, we intend to maintain the fund's high quality as we focus on the fund's objectives of income, capital preservation, and liquidity.

MARKET VOLATILITY CAN SIGNIFICANTLY AFFECT SHORT-TERM PERFORMANCE, AND CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN THE PERFORMANCE DATA QUOTED. THE PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE RESULTS. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST.

The yield quotation more closely reflects the current earnings of the fund than the total return quotation. NOTES TO PERFORMANCE SUMMARY Performance for share classes offered after class B shares includes the performance of the fund's class B shares for periods prior to their offering. Blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the initial share class, and lower performance for share classes with lower operating expenses than the initial share class. 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. All results are historical and assume the reinvestment of dividends and capital gains. KEY RISK CONSIDERATIONS Government guarantees apply to the underlying securities only and not to the prices and yields of the portfolio. An investment in the portfolio is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the portfolio seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the portfolio. These risks may increase share price volatility. Please see the prospectus for further information regarding these and other risk considerations. This report is prepared for the general information of shareholders.

See notes to financial statements. - ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (unaudited) - ------------------------------------------------------------------------------- (1) BUSINESS AND ORGANIZATION MFS Cash Reserve Fund (the fund) is a diversified series of MFS Series Trust I (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. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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. INVESTMENT VALUATIONS - Money market instruments are valued at amortized cost, which the Trustees have determined in good faith approximates market value. The fund's use of amortized cost is subject to the fund's compliance with certain conditions as specified under Rule 2a-7 of the Investment Company Act of 1940. REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with institutions that the fund's investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The fund requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. The fund 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 fund under each such repurchase agreement. The fund, 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. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized and accreted for financial statement purposes and tax reporting purposes in accordance with generally accepted accounting principles and federal tax regulations, respectively. FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. This amount for the six months ended February 29, 2004, is shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The fund'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 tax-exempt and taxable net 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 fund 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. The tax character of distributions declared for the years ended August 31, 2003 and August 31, 2002 was as follows: 8/31/03 8/31/02 Distributions declared from ordinary income $1,788,868 $5,966,964 - ------------------------------------------------------------------------------ As of August 31, 2003, the components of distributable earnings on a tax basis were as follows: Undistributed ordinary income $71,871 - --------------------------------------------------------------------------- Other temporary differences (71,116) - --------------------------------------------------------------------------- MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple classes of shares, which differ in their respective distribution and service fees. All shareholders bear the common expenses of the fund based on the value of settled shares outstanding of each class, without distinction between share classes. 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 529B shares will convert to Class A and Class 529A shares, respectively approximately eight years after purchase. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund has an investment advisory agreement with 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 0.55% of the fund's average daily net assets. The investment adviser has contractually agreed to waive a portion of its fee, which is shown as a reduction of total expenses in the Statement of Operations. Management fees incurred for the six months ended February 29, 2004 were 0.45% of average daily net assets on an annualized basis. As part of the settlement agreement with the New York Attorney General concerning market timing and related matters, MFS has agreed to reduce the fund's management fee to 0.15% of average daily net assets for the period March 1, 2004 through February 28, 2009. During this time period, the Board of Trustees will continue to review the appropriateness of all advisory fees in accordance with their oversight responsibilities. After February 28, 2009 the management fee will be determined in accordance with then existing review policies approved by the Board of Trustees overseeing the fund. The fund pays compensation to the Independent Trustees ("Trustees") in the form of both a retainer and attendance fees, and pays no compensation directly to its Trustees who are officers of the investment adviser, or to officers of the fund, all of whom receive remuneration for their services to the fund from MFS. Certain officers and Trustees of the fund are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The fund has an unfunded, defined benefit plan for retired Trustees. Included in Trustees' compensation is a pension expense of $2,107 for retired trustees for the six months ended February 29, 2004. ADMINISTRATOR - The fund has an administrative services agreement with MFS to provide the fund with certain financial, legal, shareholder communications, compliance, and other administrative services. As a partial reimbursement for the cost of providing these services, the fund pays MFS an administrative fee up to the following annual percentage rates of the fund'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% ---------------------------------------------------------- DISTRIBUTOR - The Trustees have adopted a distribution plan for Class A, Class B, Class C, Class 529A, Class 529B and Class 529C shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as follows: The fund's distribution plan provides that the fund will pay MFD an annual percentage of its average daily net assets attributable to certain share classes in order that MFD may pay expenses on behalf of the fund related to the distribution and servicing of its shares. These expenses include a service fee paid to each securities dealer that enters into a sales agreement with MFD based on the average daily net assets of accounts attributable to such dealers. These fees are calculated based on each class' average daily net assets. The maximum distribution and service fees for each class of shares are as follows: CLASS A CLASS B CLASS C CLASS 529A CLASS 529B CLASS 529C Distribution Fee 0.10% 0.75% 0.75% 0.25% 0.75% 0.75% - ---------------------------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% 0.25% 0.25% 0.25% - ---------------------------------------------------------------------------------------------------------------------- Total Distribution Plan 0.35% 1.00% 1.00% 0.50% 1.00% 1.00% - ---------------------------------------------------------------------------------------------------------------------- Payment of the 0.10% per annum Class A distribution fee and payment of the 0.25% per annum service fee will commence on such a date as the Trustees of the fund may determine. The 0.25% per annum Class 529A service fee and 0.10% of the Class 529A distribution fee are currently being waived. The remaining 0.15% per annum Class 529A distribution fee will be implemented on such a date as the Trustees of the Trust may determine. During the period, MFD voluntarily waived receipt of a portion of the fund's distribution and service fees on Class B, Class C, Class 529B and Class 529C. MFD retains the service fee for accounts not attributable to a securities dealer, which for the six months ended February 29, 2004 amounted to: CLASS A CLASS B CLASS C CLASS 529A CLASS 529B CLASS 529C Service Fee Retained by MFD -- $5,184 $4,822 -- -- -- - ---------------------------------------------------------------------------------------------------------------------- Fees incurred under the distribution plan during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C CLASS 529A CLASS 529B CLASS 529C Total Distribution Plan -- 0.39% 0.39% -- 0.14% 0.14% - ---------------------------------------------------------------------------------------------------------------------- Certain Class A, Class C and Class 529C shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within, for Class A shares, 12 months following the purchase, and, for Class C and 529C shares, the first year from the end of the calendar month of purchase. A contingent deferred sales charge is imposed on shareholder redemptions of Class B and Class 529B shares in the event of a shareholder redemption within six years from the end of the calendar month of purchase. MFD receives all contingent deferred sales charges. Contingent deferred sales charges imposed during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C CLASS 529B CLASS 529C Contingent Deferred Sales Charges Imposed $188,680 $1,399,249 $62,165 $-- $-- - -------------------------------------------------------------------------------- The fund has and may from time to time enter into contracts with program managers and other parties which administer the tuition programs through which an investment in the fund's 529 share classes is made. The fund has entered into an agreement with MFD pursuant to which MFD receives an annual fee of up to 0.35% from the fund based solely upon the value of the fund's 529 share classes attributable to tuition programs to which MFD or a third party which contracts with MFD provides administrative services. The current fee has been established at 0.25% annually of average net assets of the fund's 529 share classes attributable to such programs. The fee may only be increased with the approval of the board of trustees that oversees the fund. The services provided by MFD or a third party with which MFD contracts include recordkeeping and tax reporting and account services, as well as services designed to maintain the program's compliance with the Internal Revenue Code and other regulatory requirements. SHAREHOLDER SERVICING AGENT - Included in shareholder servicing costs is a fee paid to MFSC, a wholly owned subsidiary of MFS, for its services as shareholder servicing agent. The fee is calculated as a percentage of the fund's average daily net assets at an annual rate of 0.11%, which amounted to $408,922 for the year six months ended February 29, 2004. Also included in shareholder servicing costs are out-of-pocket expenses, paid to MFSC, which amounted to $104,714 for the six months ended February 29, 2004, as well as other expenses paid to unaffiliated vendors.

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 plus 0.50%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each quarter. The commitment fee allocated to the fund for the six months ended February 29, 2004 was $3,200. The fund had no borrowings during the period. (7) LEGAL PROCEEDINGS On March 31, 2004, MFS settled an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. Under the terms of the settlement, in which MFS neither admitted nor denied any wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50 million in penalty to certain MFS funds, pursuant to a plan to be approved by an independent distribution consultant. The agreement with the SEC is reflected in an order of the SEC. The settlement order states that MFS failed to adequately disclose to the Boards of Trustees and to shareholders of the MFS funds the specifics of its preferred arrangements with certain brokerage firms selling MFS fund shares. The settlement order states that MFS had in place policies designed to obtain best execution of all fund trades. As part of the settlement, MFS also agreed to retain an independent compliance consultant to review the completeness of its disclosure to fund trustees and to fund shareholders of strategic alliances between MFS or its affiliates and broker-dealers and other financial advisers who support the sale of fund shares. The brokerage allocation practices which were the subject of this proceeding were discontinued by MFS in November 2003. In addition, in February, 2004, MFS reached agreement with the Securities and Exchange Commission ("SEC"), the New York Attorney General ("NYAG") and the Bureau of Securities Regulation of the State of New Hampshire ("NH") to settle administrative proceedings alleging false and misleading information in certain MFS fund prospectuses regarding market timing and related matters (the "February Settlements"). These regulators alleged that prospectus language for certain MFS funds was false and misleading because, although the prospectuses for those funds in the regulators' view indicated that the funds prohibited market timing, MFS did not limit trading activity in 11 domestic large cap stock, high grade bond and money market funds. MFS' former Chief Executive Officer, John W. Ballen, and former President, Kevin R. Parke, have also reached agreement with the SEC (Messrs. Ballen and Parke resigned their director and officer positions with MFS on February 13, 2004). Under the terms of the February Settlements, MFS and the executives neither admit nor deny wrongdoing. Under the terms of the February Settlements, a $225 million pool has been established for distribution to shareholders in certain of the MFS funds offered to retail investors ("Retail Funds"), which has been funded by MFS and of which $50 million is characterized as a penalty. This pool will be distributed in accordance with a methodology developed by an independent distribution consultant in consultation with MFS and the Boards of Trustees of the Retail Funds, and acceptable to the SEC. MFS has further agreed with the NYAG to reduce its management fees in the aggregate amount of approximately $25 million annually over the next five years, and not to increase certain management fees during this period. MFS has also paid an administrative fine to NH in the amount of $1 million, which will be used for investor education purposes (NH will retain $250,000 and $750,000 will be contributed to the North American Securities Administrators Association's Investor Protection Trust). In addition, MFS and the Retail Funds will adopt certain governance changes. Messrs. Ballen and Parke have agreed to temporary suspensions from association with any registered investment company or investment adviser, will pay approximately $315,000 each to the SEC, and resigned their positions as trustees of all MFS funds, and Mr. Ballen resigned his position as President of all MFS funds, effective February 6, 2004. Messrs. Ballen and Parke will not be returning to MFS or the MFS funds after their suspensions. Since December 2003, MFS, Sun Life Financial Inc., various MFS funds, the Trustees of these MFS funds, and certain officers of MFS have been named as defendants in multiple lawsuits filed in federal and state courts. The lawsuits variously have been commenced as class actions or individual actions on behalf of investors who purchased, held or redeemed shares of the funds during specified periods, as class actions on behalf of participants in certain retirement plan accounts, or as derivative actions on behalf of the MFS funds. The lawsuits generally allege that some or all of the defendants (i) permitted or acquiesced in market timing and/or late trading in some of the MFS funds, inadequately disclosed MFS' internal policies concerning market timing and such matters, and received excessive compensation as fiduciaries to the MFS fund, or (ii) permitted or acquiesced in the improper use of fund assets by MFS to support the distribution of fund shares and inadequately disclosed MFS' use of fund assets in this manner. The actions assert that some or all of the defendants violated the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of 1940 and the Investment Advisers Act of 1940, the Employee Retirement Income Security Act of 1974, as well as fiduciary duties and other violations of common law. The lawsuits seek unspecified compensatory damages. Insofar as any of the actions is appropriately brought derivatively on behalf of any of the MFS funds, any recovery will inure to the benefit of the funds. The defendants are reviewing the allegations of the multiple complaints and will respond appropriately. Additional lawsuits based on similar allegations may be filed in the future. Any potential resolution of these matters may include, but not be limited to, judgments or settlements for damages against MFS, the MFS funds, or any other named defendant. As noted above, as part of the regulatory settlements, MFS has established a restitution pool in the amount of $225 million to compensate certain shareholders of the Retail Funds for damages that they allegedly sustained as a result of market timing or late trading in certain of the funds, and will pay $50 million to compensate certain MFS funds based upon the amount of brokerage commissions allocated in recognition of fund sales. It is not clear whether these amounts will be sufficient to compensate shareholders for all of the damage they allegedly sustained, whether certain shareholders or putative class members may have additional claims to compensation, or whether the damages that may be awarded in any of the actions will exceed these amounts. In the event the MFS funds incur any losses, costs or expenses in connection with such lawsuits, the Boards of Trustees of the affected funds may pursue claims on behalf of such funds against any party that may have liability to the funds in respect thereof. Review of these matters by the independent Trustees of the MFS funds and their counsel is continuing. There can be no assurance that these regulatory actions and lawsuits, or the adverse publicity associated with these developments will not result in increased fund redemptions, reduced sales of fund shares, or other adverse consequences to the funds. - ------------------------------------------------------------------------------------------------------------- TRUSTEES AND OFFICERS - ------------------------------------------------------------------------------------------------------------- The following tables present certain information regarding the Trustees and officers of MFS Series Trust I, of which the fund is a series, including their principal occupations, which, unless specific dates are shown, are of more than five years' duration, although the titles may not have been the same throughout.

INDEX DEFINITION TOKYO PRICE INDEX (TOPIX) - A measure of the broad Japanese stock market. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Class A results, including sales charge, reflect the deduction of the maximum 5.75% sales charge. Class I shares have no sales charges and are available only to certain investors. Performance for share classes offered after class A shares includes the performance of the fund's class A shares for periods prior to their offering. Blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the initial share class, and lower performance for share classes with lower operating expenses than the initial share class. Performance results reflect any applicable subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance would be less favorable. Please see the prospectus and financial statements for complete details. KEY RISK CONSIDERATIONS Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. Because the portfolio invests in a limited number of companies a change in one security's value may have a more significant effect on the portfolio's value. The portfolio may participate in the initial public offering (IPO) market, and a significant portion of the portfolio's returns may be attributable to investment in IPOs, which may have greater impact on performance of a portfolio while its asset base is small. There is no guarantee the portfolio will experience similar performance as its assets grow. The portfolio may invest a substantial amount of its assets in issuers located in a limited number of countries and therefore is susceptible to adverse economic, political or regulatory developments affecting those countries. These risks may increase share price volatility. Please see the prospectus for more information regarding these and other risk considerations. This report is prepared for the general information of shareholders. It is authorized for distribution to prospective investors only when preceded or accompanied by a current prospectus. - ------------------------------------------------------------------------------------------------- PORTFOLIO OF INVESTMENTS (unaudited) - 2/29/04 - ------------------------------------------------------------------------------------------------- The Portfolio of Investments is a complete list of all securities owned by your fund.

See notes to financial statements. - ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (unaudited) - ------------------------------------------------------------------------------- (1) BUSINESS AND ORGANIZATION MFS Japan Equity Fund (the fund) is a non-diversified series of MFS Series Trust I (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. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 fund 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 - The fund uses independent pricing services approved by the Board of Trustees wherever possible to value its portfolio securities. Portfolio securities are valued at current market prices where current market prices are readily available, or the fund may fair value portfolio securities under the direction of the Board of Trustees when a determination is made that current market prices are not readily available. Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Equity securities for which it is determined that current market prices are not readily available will be fair valued under the direction of the Board of Trustees. The fund may also fair value foreign equity securities in cases where closing market prices are not readily available or are deemed not reflective of readily available market prices. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the fund calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the fund may utilize information from an external vendor or other sources to adjust closing market prices of foreign equity securities to reflect what it believes to be the fair value of the securities as of the fund's valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes market value as determined by the Board of Trustees. 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. REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with institutions that the fund's investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The fund requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. The fund 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 fund under each such repurchase agreement. The fund, 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 - 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. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with accounting principles generally accepted in the United States of America. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. This amount, for the six months ended February 29, 2004, is shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The fund'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 fund 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. Common types of book and tax differences that could occur include differences in accounting for currency transactions, derivatives, and, capital losses. The fund paid no distributions for the years ended August 31, 2003 and August 31, 2002. As of August 31, 2003 the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $-- ------------------------------------------------------ Undistributed long-term capital gain -- ------------------------------------------------------ Capital loss carryforward (1,813,920) ------------------------------------------------------ Unrealized appreciation 852,768 ------------------------------------------------------ Other temporary differences -- ------------------------------------------------------ For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on: EXPIRATION DATE August 31, 2008 $(63,475) ------------------------------------------------------ August 31, 2009 (125,721) ------------------------------------------------------ August 31, 2010 (1,125,533) ------------------------------------------------------ August 31, 2011 (499,191) ------------------------------------------------------ Total $(1,813,920) ------------------------------------------------------ MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple classes of shares, which differ in their respective distribution and service fees. All shareholders bear the common expenses of the fund based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund 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 1.00% of the fund's average daily net assets. MFS has contractually agreed, subject to reimbursement, to bear a portion of the fund's "Other Expenses", which are defined as the fund's operating expenses, exclusive of management, distribution and service, and certain other fees and expenses, such that Other Expenses do not exceed 0.25% annually. This arrangement is effected by MFS bearing all of the fund's Other Expenses during the fund's fiscal year and the fund paying MFS an expense reimbursement fee not greater than 0.25% of average daily net assets for Class A, and Class I. To the extent that the expense reimbursement fee exceeds the fund's actual expenses, the excess will be applied to unreimbursed amounts paid by MFS under the current agreement. This agreement will terminate on the earlier of December 31, 2004 or such date as all expenses previously borne by MFS under the agreement have been paid by the fund. At February 29, 2004 aggregate unreimbursed expenses amounted to $92,941. The fund pays compensation to the Independent Trustees ("Trustees") in the form of both a retainer and attendance fees, and pays no compensation directly to its Trustees who are officers of the investment adviser, or to officers of the fund, all of whom receive remuneration for their services to the fund from MFS. Certain officers and Trustees of the fund are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The Trustees currently are not receiving any payment for their services for the fund. ADMINISTRATOR - The fund has an administrative services agreement with MFS to provide the fund with certain financial, legal, shareholder communications, compliance, and other administrative services. As a partial reimbursement for the cost of providing these services, the fund pays MFS an administrative fee up to the following annual percentage rates of the fund'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% ------------------------------------------------------ DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, as distributor, did not receive any sales charges on Class A shares for the fund for the six months ended February 29, 2004. The Trustees have adopted a distribution plan for Class A shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as follows: The fund's distribution plan provides that the fund will pay MFD an annual percentage of its average daily net assets attributable to certain share classes in order that MFD may pay expenses on behalf of the fund related to the distribution and servicing of its shares. These expenses include a service fee paid to each securities dealer that enters into a sales agreement with MFD based on the average daily net assets of accounts attributable to such dealers. These fees are calculated based on each class' average daily net assets. The maximum distribution and service fees for each class of shares are as follows: Distribution Fee 0.10% ------------------------------------------------------ Service Fee 0.25% ------------------------------------------------------ Total Distribution Plan 0.35% ------------------------------------------------------ The fund's payment of the 0.10% per annum Class A distribution fee and the 0.25% per annum Class A service fee are currently being waived and will be implemented on such a date as the Trustees of the fund may determine. Certain Class A shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within, for class A shares, 12 months following the purchase. MFD receives all contingent deferred sales charges. There were no contingent deferred sales charges imposed on Class A during the six months ended February 29, 2004. SHAREHOLDER SERVICING AGENT - Included in shareholder servicing costs is a fee paid to MFSC, a wholly owned subsidiary of MFS, for its services as shareholder servicing agent. The fee is calculated as a percentage of the fund's average daily net assets at an annual rate of 0.11%, which amounted to $2,654 for the six months ended February 29, 2004. Also included in shareholder servicing costs are out-of-pocket expenses, paid to MFSC, which amounted to $62 for the six months ended February 29, 2004, as well as other expenses paid to unaffiliated vendors. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $2,852,982 and $2,568,669, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the fund, as computed on a federal income tax basis, are as follows: Aggregate cost $4,079,342 ------------------------------------------------------ Gross unrealized appreciation $962,296 ------------------------------------------------------ Gross unrealized depreciation (73,237) ------------------------------------------------------ Net unrealized appreciation $889,059 ------------------------------------------------------ (5) SHARES OF BENEFICIAL INTEREST The fund's Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. Transactions in fund shares were as follows: Six months ended 2/29/04 Year ended 8/31/03 SHARES AMOUNT SHARES AMOUNT CLASS A SHARES Shares sold 13,993 $124,612 7,249 $44,597 - -------------------------------------------------------------------------------- Shares reacquired (12,559) (112,582) (431) (2,745) - -------------------------------------------------------------------------------- Net increase 1,434 $12,030 6,818 $41,852 - -------------------------------------------------------------------------------- CLASS I SHARES Shares sold 34,706 $307,938 62,702 $414,034 - -------------------------------------------------------------------------------- Shares reacquired (15,146) (136,906) (63,841) (417,808) - -------------------------------------------------------------------------------- Net increase (decrease) 19,560 $171,032 (1,139) $(3,774) - -------------------------------------------------------------------------------- (6) LINE OF CREDIT The fund and other affiliated funds participate in an $800 million 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 plus 0.50%. In addition, a commitment fee, based on the average daily unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the fund for the six months ended February 29, 2004 was $18. The fund had no borrowings during the period. (7) FINANCIAL INSTRUMENTS The fund 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 fund 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. There were no outstanding financial instruments with off-balance-sheet risk at the end of the period. (8) LEGAL PROCEEDINGS On March 31, 2004, MFS settled an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. Under the terms of the settlement, in which MFS neither admitted nor denied any wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50 million in penalty to certain MFS funds, pursuant to a plan to be approved by an independent distribution consultant. The agreement with the SEC is reflected in an order of the SEC. The settlement order states that MFS failed to adequately disclose to the Boards of Trustees and to shareholders of the MFS funds the specifics of its preferred arrangements with certain brokerage firms selling MFS fund shares. The settlement order states that MFS had in place policies designed to obtain best execution of all fund trades. As part of the settlement, MFS also agreed to retain an independent compliance consultant to review the completeness of its disclosure to fund trustees and to fund shareholders of strategic alliances between MFS or its affiliates and broker-dealers and other financial advisers who support the sale of fund shares. The brokerage allocation practices which were the subject of this proceeding were discontinued by MFS in November 2003. In addition, in February, 2004, MFS reached agreement with the Securities and Exchange Commission ("SEC"), the New York Attorney General ("NYAG") and the Bureau of Securities Regulation of the State of New Hampshire ("NH") to settle administrative proceedings alleging false and misleading information in certain MFS fund prospectuses regarding market timing and related matters (the "February Settlements"). These regulators alleged that prospectus language for certain MFS funds was false and misleading because, although the prospectuses for those funds in the regulators' view indicated that the funds prohibited market timing, MFS did not limit trading activity in 11 domestic large cap stock, high grade bond and money market funds. MFS' former Chief Executive Officer, John W. Ballen, and former President, Kevin R. Parke, have also reached agreement with the SEC (Messrs. Ballen and Parke resigned their director and officer positions with MFS on February 13, 2004). Under the terms of the February Settlements, MFS and the executives neither admit nor deny wrongdoing. Under the terms of the February Settlements, a $225 million pool has been established for distribution to shareholders in certain of the MFS funds offered to retail investors ("Retail Funds"), which has been funded by MFS and of which $50 million is characterized as a penalty. This pool will be distributed in accordance with a methodology developed by an independent distribution consultant in consultation with MFS and the Boards of Trustees of the Retail Funds, and acceptable to the SEC. MFS has further agreed with the NYAG to reduce its management fees in the aggregate amount of approximately $25 million annually over the next five years, and not to increase certain management fees during this period. MFS has also paid an administrative fine to NH in the amount of $1 million, which will be used for investor education purposes (NH will retain $250,000 and $750,000 will be contributed to the North American Securities Administrators Association's Investor Protection Trust). In addition, MFS and the Retail Funds will adopt certain governance changes. Messrs. Ballen and Parke have agreed to temporary suspensions from association with any registered investment company or investment adviser, will pay approximately $315,000 each to the SEC, and resigned their positions as trustees of all MFS funds, and Mr. Ballen resigned his position as President of all MFS funds, effective February 6, 2004. Messrs. Ballen and Parke will not be returning to MFS or the MFS funds after their suspensions. Since December 2003, MFS, Sun Life Financial Inc., various MFS funds, the Trustees of these MFS funds, and certain officers of MFS have been named as defendants in multiple lawsuits filed in federal and state courts. The lawsuits variously have been commenced as class actions or individual actions on behalf of investors who purchased, held or redeemed shares of the funds during specified periods, as class actions on behalf of participants in certain retirement plan accounts, or as derivative actions on behalf of the MFS funds. The lawsuits generally allege that some or all of the defendants (i) permitted or acquiesced in market timing and/or late trading in some of the MFS funds, inadequately disclosed MFS' internal policies concerning market timing and such matters, and received excessive compensation as fiduciaries to the MFS fund, or (ii) permitted or acquiesced in the improper use of fund assets by MFS to support the distribution of fund shares and inadequately disclosed MFS' use of fund assets in this manner. The actions assert that some or all of the defendants violated the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of 1940 and the Investment Advisers Act of 1940, the Employee Retirement Income Security Act of 1974, as well as fiduciary duties and other violations of common law. The lawsuits seek unspecified compensatory damages. Insofar as any of the actions is appropriately brought derivatively on behalf of any of the MFS funds, any recovery will inure to the benefit of the funds. The defendants are reviewing the allegations of the multiple complaints and will respond appropriately. Additional lawsuits based on similar allegations may be filed in the future. Any potential resolution of these matters may include, but not be limited to, judgments or settlements for damages against MFS, the MFS funds, or any other named defendant. As noted above, as part of the regulatory settlements, MFS has established a restitution pool in the amount of $225 million to compensate certain shareholders of the Retail Funds for damages that they allegedly sustained as a result of market timing or late trading in certain of the funds, and will pay $50 million to compensate certain MFS funds based upon the amount of brokerage commissions allocated in recognition of fund sales. It is not clear whether these amounts will be sufficient to compensate shareholders for all of the damage they allegedly sustained, whether certain shareholders or putative class members may have additional claims to compensation, or whether the damages that may be awarded in any of the actions will exceed these amounts. In the event the MFS funds incur any losses, costs or expenses in connection with such lawsuits, the Boards of Trustees of the affected funds may pursue claims on behalf of such funds against any party that may have liability to the funds in respect thereof. Review of these matters by the independent Trustees of the MFS funds and their counsel is continuing. There can be no assurance that these regulatory actions and lawsuits, or the adverse publicity associated with these developments will not result in increased fund redemptions, reduced sales of fund shares, or other adverse consequences to the funds. - -------------------------------------------------------------------------------------------------------------- TRUSTEES AND OFFICERS - -------------------------------------------------------------------------------------------------------------- The following tables present certain information regarding the Trustees and officers of MFS Series Trust I, of which the fund is a series, including their principal occupations, which, unless specific dates are shown, are of more than five years' duration, although the titles may not have been the same throughout.

Manning] As the firm's new Chief Executive Officer, I want to thank you for your continued trust in MFS and tell you about the series of actions we have taken since our recent settlements with the regulators. These actions are designed to enhance the governance structure of the MFS funds, tighten our business practices, and strengthen the management team at MFS. In early February, Robert Pozen joined MFS as non-executive Chairman. A seasoned veteran of the mutual fund industry, Bob has held prior positions as President of Fidelity Management & Research Company, as Associate General Counsel of the Securities and Exchange Commission, and as a visiting professor at Harvard Law School. In an effort to develop and implement policies that we believe will set a new standard in regulatory compliance, MFS has hired two new senior executives. Jeffrey Carp is joining us as General Counsel with responsibility for all of our legal affairs. Previously he was a senior partner with the law firm of Hale and Dorr LLP. Also joining MFS in the new position of Executive Vice President of Regulatory Affairs is Maria Dwyer, who returned to the firm after serving as a senior executive at Fidelity. At MFS, Maria is in charge of compliance, internal audit, and fund treasury. In the area of governance, we have taken steps to enhance the independence of our funds' boards of trustees to better protect the interests of shareholders. We have independent board chairs and at least 75% of the trustees are independent. The trustees will appoint not only their own counsel but also an independent compliance officer. This officer will assist the boards and their committees in monitoring the MFS funds' compliance with federal and state regulations. In February, MFS reached agreements with federal and state regulators to settle their administrative proceedings against the firm and two senior executives in connection with market timing and related issues. Under the terms of the settlements, we agreed to pay $225 million to compensate affected retail fund shareholders. The $225 million will be distributed in accordance with a distribution plan developed by an independent consultant. We have further agreed with state regulators to reduce management fees on certain funds we advise by approximately $25 million annually over the next five years and to pay an administrative fine of $1 million, which will be used for the purpose of investor education. We have introduced a set of policies designed to protect the MFS funds and MFS fund shareholders from market timing abuses. By July, all MFS retail funds, except money market funds, will have a 2% redemption fee on short-term trades. Our global, international, high-yield, mid- and small-cap funds will impose the 2% fee on redemptions or exchanges of fund shares made within 30 calendar days of a share purchase. For all other MFS funds, except money market funds, the 2% fee will be imposed on redemptions or exchanges made within 5 business days of a share purchase. See the fund prospectus for more information. We continue to use fair value pricing, a strategy that minimizes the potential for investors to take advantage of "stale" prices. These can occur, as one example, when funds own foreign securities whose prices close on overseas exchanges in different time zones. At the same time, we enhanced our monitoring of excessive trading. We did so by increasing our staff and updating our computer systems to improve our ability to detect excessive trading in our funds. Finally, we are supporting industry efforts to establish a "hard" 4 p.m. close on all trading, which would prevent the possibility of late trading. In March, MFS reached a second settlement with the SEC under an administrative proceeding resolving the SEC's investigation into how we disclosed brokerage allocation practices in connection with fund sales. According to the settlement order, we did not effectively disclose the potential conflict of interest that may arise from these arrangements. Under the terms of the settlement, MFS has agreed to pay one dollar in disgorgement and $50 million in penalty to MFS fund shareholders. The settlement noted that MFS had policies in place designed to obtain best execution of all trades of securities within MFS portfolios. This past November, MFS eliminated the above mentioned practice of directing brokerage commissions to certain firms in recognition of fund sales. Additionally, we announced in March that we would ban the use of soft dollars to acquire third-party securities research and market data. Soft dollars are permitted under federal securities laws. In fact, it is a common industry practice to use a portion of the brokerage commissions to pay for certain research and execution products and services that are provided to asset managers. MFS will now pay cash out of its own pocket for third-party research and market data. MFS continues to be financially strong, with more than U.S. $140 billion (as of 12/31/03) in assets under management, which continued to be stable during the first quarter of 2004. We also have the full support of our parent company, Sun Life Financial, an internationally diversified financial services firm that manages more than U.S. $269 billion (as of 12/31/03). We chose to settle these two proceedings with the SEC so we could concentrate on serving our fund shareholders. As Chief Investment Officer, my focus is on ensuring that our portfolio teams work closely together and take full advantage of all the resources available to them to deliver the best possible investment performance. As the inventor of the open-end mutual fund in America in 1924, MFS has a strong tradition and culture of innovation. By strengthening our business and governance practices, we believe we have an unprecedented opportunity to set a new standard in the mutual fund industry. As I look ahead, I do so with confidence. The collaboration among MFS employees, many of whom have worked at the firm for their entire careers, continues as we remain singularly dedicated to our clients. It has been our sincere privilege to serve you, and we thank you for the confidence that you have shown in MFS. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer MFS Investment Management(R) March 15, 2004 Note to Shareholders: On February 6, 2004, Jeffrey L. Shames retired as Chairman of MFS. Robert Pozen was named as non-executive Chairman. Also, on February 6, 2004, Robert J. Manning was appointed Chief Executive Officer, President, and Chief Investment Officer. The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed. - ------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - ------------------------------------------------------------------------------- THE MFS(R) DIFFERENCE For 80 years MFS has been offering investors clear paths to pursuing specific investment objectives. Today, millions of individuals and thousands of institutions all over the world look to MFS to manage their assets with insight and care. Our success, we believe, has to do with the fact that we see investors as people with plans, not just dollars to invest. When you invest with MFS, you invest with a company dedicated to helping you realize your long-term financial goals. INVESTORS CHOOSE MFS FOR OUR o global asset management expertise across all asset classes o time-tested money management process for pursuing consistent results o full spectrum of investment products backed by MFS Original Research(R) o resources and services that match real-life needs TURNING INFORMATION INTO OPPORTUNITY Sound investments begin with sound information. MFS has been doing its own research and analyzing findings in-house for decades. The process we use to uncover opportunity is called MFS Original Research(R). MFS ORIGINAL RESEARCH INVOLVES: o meeting with the management of 3,000 companies each year to assess their business plans and the managers' ability to execute those plans o making onsite visits to more than 2,000 companies annually to gain first-hand knowledge of their operations and products o analyzing financial statements and balance sheets o talking extensively with companies' customers and competitors o developing our own proprietary estimates of companies' earnings - ------------------------------------------------------------------------------- MANAGEMENT REVIEW - ------------------------------------------------------------------------------- MARKET ENVIRONMENT The turnaround in global stock markets that began in the spring of 2003 continued for most of the six-month period ended February 29, 2004. The release of increasingly positive economic numbers as the period progressed, particularly with regard to corporate earnings and GDP (gross domestic product) growth, helped drive the equity rally. By late 2003, corporate capital spending, which had been weak for some time, had also begun to accelerate. Another driver of the equity rally, in our view, was the U.S. Federal Reserve Board's decision to leave interest rates at a four-decade low throughout the period. While energy prices rose late in the period, core inflation - excluding volatile food and energy prices - remained very low relative to historical averages. DETRACTORS FROM PERFORMANCE Over the six-month period ended February 29, 2004, the fund outperformed the average large-cap growth fund, as reported by Lipper Inc., but underperformed its benchmark, the Russell 1000 Growth Index. Relative to our benchmark, leisure was the fund's weakest area over the period. Stock selection as well as an overweighting in the sector hurt results as the sector underperformed the broad market. Going into the period, we believed our positions in advertising-sensitive broadcasting stocks would benefit from increased ad spending as the U.S. economy recovered. However, advertising spending, particularly in local markets, stagnated somewhat during the period. Fund positions such as media conglomerate Viacom, radio station operator Clear Channel Communications and radio and television programming provider Westwood One detracted from relative performance. As of the end of the period, however, all three stocks remained significant positions in the portfolio. We believed they could benefit in 2004 from the confluence of a stronger economy, a U.S. presidential election, and the summer Olympics. - ----------------------------------------------- TOP 5 SECTOR WEIGHTINGS AS OF 2/29/04 TECHNOLOGY 32.7% - ----------------------------------------------- HEALTH CARE 14.4% - ----------------------------------------------- FINANCIAL SERVICES 14.1% - ----------------------------------------------- LEISURE 12.9% - ----------------------------------------------- RETAILING 10.9% - ----------------------------------------------- The portfolio is actively managed, and current weightings may be different. - ----------------------------------------------- In the health care sector, stock selection and an underweighting relative to our benchmark held back performance as the sector did well over the period. Our biggest relative detractor was pharmaceutical giant Pfizer. Although we held a significant position in the stock as its shares gained more than the broad market, relative performance suffered because we were underweighted in the stock compared with our benchmark. Underweighting consumer staples concerns also hurt performance over the period as investors, in our view, began to favor some of the more defensive stocks they had shunned in early and mid-2003. More specifically, not owning food and tobacco conglomerate Altria Group (formerly Philip Morris) and consumer products firm Procter & Gamble detracted from relative returns over the period. (Those stocks, however, were not among the fund's top detractors for the period.) Individual stocks in other sectors that meaningfully held back relative results included our position in moderate-priced apparel retailer Kohl's. We believe mediocre merchandising, together with adverse weather in key markets, caused the firm to report weak operating results. We viewed these issues as surmountable and maintained our Kohl's holding over the period. Relative performance was also hurt by our overweighted position in financial transaction processor BISYS Group, whose stock fell in price over the period. And while overall stock selection in the technology sector did help performance, a number of our technology stocks declined in price and were key detractors during the period. These included electronic commerce firm InterActiveCorp, storage solution provider VERITAS Software, and semiconductor manufacturing equipment company Novellus Systems. On a relative basis, our position in cellular phone technology firm QUALCOMM also detracted from performance because we sold our holding during the period and missed much of the stock's strong performance. The portfolio's cash position also detracted from relative performance. As with nearly all mutual funds, this portfolio holds some cash to buy new holdings and to cover investor exchanges or redemptions. In a period when equity markets rose sharply, cash hurt performance against our benchmark, the Russell 1000 Growth Index, which has no cash position. CONTRIBUTORS TO PERFORMANCE Stock selection in the technology sector contributed strongly to relative results. A number of technology stocks were among the fund's top performers for the period, including telecom infrastructure firm Nortel Networks, programmable logic designer/manufacturer Xilinx, and e-business services provider Akamai Technologies. Not owning semiconductor giant Intel also helped relative results as the stock, which had soared for much of 2003, retreated in early 2004. Concern about the stock's high valuation had led us to avoid Intel. A relative overweighting in the utilities and communications sector also helped relative returns as that sector was by far the strongest-performing area in the Russell 1000 Growth Index for the period. Cellular phone company Sprint PCS, whose stock appreciated sharply, was among our holdings in the sector. In the industrial goods and services area, stock selection and an underweighting in the sector both helped fund performance. Our strongest contributor in the sector was conglomerate Tyco International, which did well as new management began to turn around the firm's performance. An overweighting in the financial services sector also added to results as that sector outperformed the broad market. Insurance and reinsurance firm Ace Ltd. was our largest contributor in that sector. Respectfully, /s/ S. Irfan Ali S.

INDEX DEFINITION THE RUSSELL 1000 GROWTH INDEX - measures the performance of large-cap U.S. growth stocks. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY A portion of the returns shown is attributable to the receipt of a non-recurring payment in settlement of a class action lawsuit. Class A and 529A results, including sales charge, reflect the deduction of the maximum 5.75% sales charge. Class B and 529B results, including sales charge, reflect the deduction of the applicable contingent deferred sales charge (CDSC), which declines over six years from 4% to 0%. Class C and 529C results, including sales charge, redeemed within one year from the end of the calendar month of purchase reflect the deduction of the 1% CDSC. Class I shares have no sales charge and are available only to certain investors. Class J results, including sales charge, reflect the deduction of the maximum 3% sales charge and are available only to residents of Japan. Class R1 and R2 shares have no sales charge and are available only to certain retirement plans. Class 529A, 529B, and 529C shares are only available in conjunction with qualified tuition programs, such as the MFS 529 Savings Plan. Performance for share classes offered after class A shares includes the performance of the fund's class A shares for periods prior to their offering. Blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the initial share class, and lower performance for share classes with lower operating expenses than the initial share class. 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. All results are historical and include the reinvestment of dividends and capital gains. KEY RISK CONSIDERATIONS Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. These risks may increase share price volatility. Please see the prospectus for further information regarding these and other risk considerations.

See notes to financial statements. - ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (unaudited) - ------------------------------------------------------------------------------- (1) BUSINESS AND ORGANIZATION MFS Strategic Growth Fund (the fund) is a diversified series of MFS Series Trust I (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. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 fund 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 - The fund uses independent pricing services approved by the Board of Trustees wherever possible to value its portfolio securities. Portfolio securities are valued at current market prices where current market prices are readily available, or the fund may fair value portfolio securities under the direction of the Board of Trustees when a determination is made that current market prices are not readily available. Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Equity securities for which it is determined that current market prices are not readily available will be fair valued under the direction of the Board of Trustees. The fund may also fair value foreign equity securities in cases where closing market prices are not readily available or are deemed not reflective of readily available market prices. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the fund calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the fund may utilize information from an external vendor or other sources to adjust closing market prices of foreign equity securities to reflect what it believes to be the fair value of the securities as of the fund's valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes market value as determined by the Board of Trustees. 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. REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with institutions that the fund's investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The fund requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. The fund 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 fund under each such repurchase agreement. The fund, 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. 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 fund or other MFS funds selected by the Trustee. Deferred amounts represent an unsecured obligation of the fund until distributed in accordance with the Plan. Included in other assets and accrued expenses and other liabilities is $3,964 of Deferred Trustees' Compensation. SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as lending agent, may loan the securities of the fund to certain qualified institutions (the "Borrowers") approved by the fund. 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 fund with indemnification against Borrower default. The fund bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or 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 fund and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the fund 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. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with accounting principles generally accepted in the United States of America. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. During the six months ended February 29, 2004, the fund's custodian fees were reduced by $4,623 under this arrangement. The fund has entered into a commission recapture agreement, under which certain brokers will credit the fund a portion of the commissions generated, to offset certain expenses of the fund. For six months ended February 29, 2004, the fund's miscellaneous expenses were reduced by $34,136 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The fund'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 fund 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. Common types of book and tax differences that could occur include differences in accounting for currency transactions and capital losses. The tax character of distributions declared for the years ended August 31, 2003 and August 31, 2002 was as follows: 8/31/03 8/31/02 Distributions declared from long-term capital gain $-- $10,100,957 - -------------------------------------------------------------------------------- As of August 31, 2003, the components of accumulated losses on a tax basis were as follows: Capital loss carryforward $(1,127,598,053) - ------------------------------------------------------------------------------ Unrealized depreciation (37,942,452) - ------------------------------------------------------------------------------ Post-October capital loss deferral (128,838,894) - ------------------------------------------------------------------------------ Other temporary differences (10,070,407) - ------------------------------------------------------------------------------ Post-October capital loss deferrals represent losses realized during the current fiscal year, but recognized for tax purposes in the next fiscal year. For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on August 31, 2010, ($827,855,260) and August 31, 2011 ($299,742,793). MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple classes of shares, which differ in their respective distribution and service fees. All shareholders bear the common expenses of the fund based on daily net assets of each class, without distinction between share classes. 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 529B shares will convert to Class A and Class 529A shares, respectively approximately eight years after purchase. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund 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 0.75% of the fund's average daily net assets. As part of the settlement agreement with the New York Attorney General concerning market timing and related matters, MFS has agreed to reduce the fund's management fee to 0.65% of average daily net assets for the period March 1, 2004 through February 28, 2009. During this time period, the Board of Trustees will continue to review the appropriateness of all advisory fees in accordance with their oversight responsibilities. After February 28, 2009 the management fee will be determined in accordance with then existing review policies approved by the Board of Trustees overseeing the fund. The fund pays compensation to the Independent Trustees ("Trustees") in the form of both a retainer and attendance fees, and pays no compensation directly to its Trustees who are officers of the investment adviser, or to officers of the fund, all of whom receive remuneration for their services to the fund from MFS. Certain officers and Trustees of the fund are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The fund has an unfunded, defined benefit plan for retired Trustees and an unfunded retirement benefit deferral plan for current Trustees. Included in Trustees' compensation is a net decrease of $6,902 as a result of the change in the fund's pension liability for current Trustees and a pension expense of $1,129 for retired trustees for the six months ended February 29, 2004. ADMINISTRATOR - The fund has an administrative services agreement with MFS to provide the fund with certain financial, legal, shareholder communications, compliance, and other administrative services. As a partial reimbursement for the cost of providing these services, the fund pays MFS an administrative fee up to the following annual percentage rates of the fund'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% ---------------------------------------------------------- In addition to the administrative services provided by MFS to the fund as described above, MFS is responsible for providing certain administrative services with respect to class R2 shares. These services include various administrative, recordkeeping, and communication/educational services with respect to the retirement plans which invest in class R2 shares, and may be provided directly by MFS or by a third party. The fund pays an annual 0.25% administrative service fee solely from the assets of class R2 shares to MFS for the provision of these services. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, as distributor, received $49,939 and $913 for the six months ended February 29, 2004, as its portion of the sales charge on sales of Class A and Class 529A shares of the fund, respectively. The Trustees have adopted a distribution plan for Class A, Class B, Class C, Class J, Class R1, Class R2, Class 529A, Class 529B and Class 529C shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as follows: The fund's distribution plan provides that the fund will pay MFD an annual percentage of its average daily net assets attributable to certain share classes in order that MFD may pay expenses on behalf of the fund related to the distribution and servicing of its shares. These expenses include a service fee paid to each securities dealer that enters into a sales agreement with MFD based on the average daily net assets of accounts attributable to such dealers. These fees are calculated based on each class' average daily net assets. The maximum distribution and service fees for each class of shares are as follows: CLASS A CLASS B CLASS C CLASS J CLASS R1 CLASS R2 Distribution Fee 0.10% 0.75% 0.75% 0.75% 0.25% 0.25% - -------------------------------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% 0.25% 0.25% 0.25% - -------------------------------------------------------------------------------------------------------------------------- Total Distribution Plan 0.35% 1.00% 1.00% 1.00% 0.50% 0.50% - -------------------------------------------------------------------------------------------------------------------------- CLASS 529A CLASS 529B CLASS 529C Distribution Fee 0.25% 0.75% 0.75% - -------------------------------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% - -------------------------------------------------------------------------------------------------------------------------- Total Distribution Plan 0.50% 1.00% 1.00% - -------------------------------------------------------------------------------------------------------------------------- MFD retains the service fee for accounts not attributable to a securities dealer, which for the six months ended February 29, 2004, amounted to: CLASS A CLASS B CLASS C CLASS J CLASS R1 CLASS R2 Service Fee Retained by MFD $130,852 $4,145 $3,335 $-- $-- $-- - -------------------------------------------------------------------------------------------------------------------------- CLASS 529A CLASS 529B CLASS 529C Service Fee Retained by MFD $164 $6 $25 - -------------------------------------------------------------------------------------------------------------------------- Payment of the 0.15% per annum portion of the Class 529A distribution fee that is not currently being charged will be implemented on such date as the Trustees of the trust may determine. Fees incurred under the distribution plan during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C CLASS J CLASS R1 CLASS R2 Total Distribution Plan 0.35% 1.00% 1.00% 1.00% 0.50% 0.50% - -------------------------------------------------------------------------------------------------------------------------- CLASS 529A CLASS 529B CLASS 529C Total Distribution Plan 0.35% 1.00% 1.00% - -------------------------------------------------------------------------------------------------------------------------- Class J shares are available for distribution through Monex, Inc. ("Monex") and Citicorp Securities (Japan) Ltd. ("Citicorp") and their network of financial intermediaries. Monex also serves as the fund's Agent Securities Company in Japan, and in that capacity represents the fund before Japanese regulatory authorities. MFD will pay to Monex and Citicorp all of the service fee and a portion of the distribution fee attributable to Class J shares. Out of the distribution fee, MFD will pay to Monex and Citicorp 0.575% per annum of average daily net assets attributable to Class J shares. A portion of the distribution fee equal to 0.05% per annum of the fund's average daily net assets attributable to Class J shares is paid to Monex to cover its service as the fund's Agent Securities Company. MFD retains the remaining 0.125%. Certain Class A, Class C and Class 529C shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within, for Class A shares, 12 months following the purchase, and, for Class C and 529C shares, the first year from the end of the calendar month of purchase. A contingent deferred sales charge is imposed on shareholder redemptions of Class B and Class 529B shares in the event of a shareholder redemption within six years from the end of the calendar month of purchase. MFD receives all contingent deferred sales charges. Contingent deferred sales charges imposed during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C CLASS 529B CLASS 529C Contingent Deferred Sales Charges Imposed $6,866 $519,925 $1,539 $-- $-- - -------------------------------------------------------------------------------- The fund has and may from time to time enter into contracts with program managers and other parties which administer the tuition programs through which an investment in the fund's 529 share classes is made. The fund has entered into an agreement with MFD pursuant to which MFD receives an annual fee of up to 0.35% from the fund based solely upon the value of the fund's 529 share classes attributable to tuition programs to which MFD or a third party which contracts with MFD provides administrative services. The current fee has been established at 0.25% annually of average net assets of the fund's 529 share classes attributable to such programs. The fee may only be increased with the approval of the board of trustees that oversees the fund. The services provided by MFD or a third party with which MFD contracts include recordkeeping and tax reporting and account services, as well as services designed to maintain the program's compliance with the Internal Revenue Code and other regulatory requirements. SHAREHOLDER SERVICING AGENT - Included in shareholder servicing costs is a fee paid to MFSC, a wholly owned subsidiary of MFS, for its services as shareholder servicing agent. The fee is calculated as a percentage of the fund's average daily net assets at an annual rate of 0.11%, which amounted to $880,030 for the six months ended February 29, 2004. Also included in shareholder servicing costs are out-of-pocket expenses, paid to MFSC, which amounted to $311,591 for the six months ended February 29, 2004, as well as other expenses paid to unaffiliated vendors.

(6) LINE OF CREDIT The fund and other affiliated funds participate in an $800 million 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 plus 0.50%. In addition, a commitment fee, based on the average daily unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the fund for the six months ended February 29, 2004, was $5,423. The fund had no borrowings during the period. (7) LEGAL PROCEEDINGS On March 31, 2004, MFS settled an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. Under the terms of the settlement, in which MFS neither admitted nor denied any wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50 million in penalty to certain MFS funds, pursuant to a plan to be approved by an independent distribution consultant. The agreement with the SEC is reflected in an order of the SEC. The settlement order states that MFS failed to adequately disclose to the Boards of Trustees and to shareholders of the MFS funds the specifics of its preferred arrangements with certain brokerage firms selling MFS fund shares. The settlement order states that MFS had in place policies designed to obtain best execution of all fund trades. As part of the settlement, MFS also agreed to retain an independent compliance consultant to review the completeness of its disclosure to fund trustees and to fund shareholders of strategic alliances between MFS or its affiliates and broker-dealers and other financial advisers who support the sale of fund shares. The brokerage allocation practices which were the subject of this proceeding were discontinued by MFS in November 2003. In addition, in February, 2004, MFS reached agreement with the Securities and Exchange Commission ("SEC"), the New York Attorney General ("NYAG") and the Bureau of Securities Regulation of the State of New Hampshire ("NH") to settle administrative proceedings alleging false and misleading information in certain MFS fund prospectuses regarding market timing and related matters (the "February Settlements"). These regulators alleged that prospectus language for certain MFS funds was false and misleading because, although the prospectuses for those funds in the regulators' view indicated that the funds prohibited market timing, MFS did not limit trading activity in 11 domestic large cap stock, high grade bond and money market funds. MFS' former Chief Executive Officer, John W. Ballen, and former President, Kevin R. Parke, have also reached agreement with the SEC (Messrs. Ballen and Parke resigned their director and officer positions with MFS on February 13, 2004). Under the terms of the February Settlements, MFS and the executives neither admit nor deny wrongdoing. Under the terms of the February Settlements, a $225 million pool has been established for distribution to shareholders in certain of the MFS funds offered to retail investors ("Retail Funds"), which has been funded by MFS and of which $50 million is characterized as a penalty. This pool will be distributed in accordance with a methodology developed by an independent distribution consultant in consultation with MFS and the Boards of Trustees of the Retail Funds, and acceptable to the SEC. MFS has further agreed with the NYAG to reduce its management fees in the aggregate amount of approximately $25 million annually over the next five years, and not to increase certain management fees during this period. MFS has also paid an administrative fine to NH in the amount of $1 million, which will be used for investor education purposes (NH will retain $250,000 and $750,000 will be contributed to the North American Securities Administrators Association's Investor Protection Trust). In addition, MFS and the Retail Funds will adopt certain governance changes. Messrs. Ballen and Parke have agreed to temporary suspensions from association with any registered investment company or investment adviser, will pay approximately $315,000 each to the SEC, and resigned their positions as trustees of all MFS funds, and Mr. Ballen resigned his position as President of all MFS funds, effective February 6, 2004. Messrs. Ballen and Parke will not be returning to MFS or the MFS funds after their suspensions. Since December 2003, MFS, Sun Life Financial Inc., various MFS funds, the Trustees of these MFS funds, and certain officers of MFS have been named as defendants in multiple lawsuits filed in federal and state courts. The lawsuits variously have been commenced as class actions or individual actions on behalf of investors who purchased, held or redeemed shares of the funds during specified periods, as class actions on behalf of participants in certain retirement plan accounts, or as derivative actions on behalf of the MFS funds. The lawsuits generally allege that some or all of the defendants (i) permitted or acquiesced in market timing and/or late trading in some of the MFS funds, inadequately disclosed MFS' internal policies concerning market timing and such matters, and received excessive compensation as fiduciaries to the MFS fund, or (ii) permitted or acquiesced in the improper use of fund assets by MFS to support the distribution of fund shares and inadequately disclosed MFS' use of fund assets in this manner. The actions assert that some or all of the defendants violated the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of 1940 and the Investment Advisers Act of 1940, the Employee Retirement Income Security Act of 1974, as well as fiduciary duties and other violations of common law. The lawsuits seek unspecified compensatory damages. Insofar as any of the actions is appropriately brought derivatively on behalf of any of the MFS funds, any recovery will inure to the benefit of the funds. The defendants are reviewing the allegations of the multiple complaints and will respond appropriately. Additional lawsuits based on similar allegations may be filed in the future. Any potential resolution of these matters may include, but not be limited to, judgments or settlements for damages against MFS, the MFS funds, or any other named defendant. As noted above, as part of the regulatory settlements, MFS has established a restitution pool in the amount of $225 million to compensate certain shareholders of the Retail Funds for damages that they allegedly sustained as a result of market timing or late trading in certain of the funds, and will pay $50 million to compensate certain MFS funds based upon the amount of brokerage commissions allocated in recognition of fund sales. It is not clear whether these amounts will be sufficient to compensate shareholders for all of the damage they allegedly sustained, whether certain shareholders or putative class members may have additional claims to compensation, or whether the damages that may be awarded in any of the actions will exceed these amounts. In the event the MFS funds incur any losses, costs or expenses in connection with such lawsuits, the Boards of Trustees of the affected funds may pursue claims on behalf of such funds against any party that may have liability to the funds in respect thereof. Review of these matters by the independent Trustees of the MFS funds and their counsel is continuing. There can be no assurance that these regulatory actions and lawsuits, or the adverse publicity associated with these developments will not result in increased fund redemptions, reduced sales of fund shares, or other adverse consequences to the funds. - ----------------------------------------------------------------------------------------------------------- TRUSTEES AND OFFICERS - ----------------------------------------------------------------------------------------------------------- The following tables present certain information regarding the Trustees and officers of MFS Series Trust I, of which the fund is a series, including their principal occupations, which, unless specific dates are shown, are of more than five years' duration, although the titles may not have been the same throughout.

Manning] As the firm's new Chief Executive Officer, I want to thank you for your continued trust in MFS and tell you about the series of actions we have taken since our recent settlements with the regulators. These actions are designed to enhance the governance structure of the MFS funds, tighten our business practices, and strengthen the management team at MFS. In early February, Robert Pozen joined MFS as non-executive Chairman. A seasoned veteran of the mutual fund industry, Bob has held prior positions as President of Fidelity Management & Research Company, as Associate General Counsel of the Securities and Exchange Commission, and as a visiting professor at Harvard Law School. In an effort to develop and implement policies that we believe will set a new standard in regulatory compliance, MFS has hired two new senior executives. Jeffrey Carp is joining us as General Counsel with responsibility for all of our legal affairs. Previously he was a senior partner with the law firm of Hale and Dorr LLP. Also joining MFS in the new position of Executive Vice President of Regulatory Affairs is Maria Dwyer, who returned to the firm after serving as a senior executive at Fidelity. At MFS, Maria is in charge of compliance, internal audit, and fund treasury. In the area of governance, we have taken steps to enhance the independence of our funds' boards of trustees to better protect the interests of shareholders. We have independent board chairs and at least 75% of the trustees are independent. The trustees will appoint not only their own counsel but also an independent compliance officer. This officer will assist the boards and their committees in monitoring the MFS funds' compliance with federal and state regulations. In February, MFS reached agreements with federal and state regulators to settle their administrative proceedings against the firm and two senior executives in connection with market timing and related issues. Under the terms of the settlements, we agreed to pay $225 million to compensate affected retail fund shareholders. The $225 million will be distributed in accordance with a distribution plan developed by an independent consultant. We have further agreed with state regulators to reduce management fees on certain funds we advise by approximately $25 million annually over the next five years and to pay an administrative fine of $1 million, which will be used for the purpose of investor education. We have introduced a set of policies designed to protect the MFS funds and MFS fund shareholders from market timing abuses. By July, all MFS retail funds, except money market funds, will have a 2% redemption fee on short-term trades. Our global, international, high-yield, mid- and small-cap funds will impose the 2% fee on redemptions or exchanges of fund shares made within 30 calendar days of a share purchase. For all other MFS funds, except money market funds, the 2% fee will be imposed on redemptions or exchanges made within 5 business days of a share purchase. See the fund prospectus for more information. We continue to use fair value pricing, a strategy that minimizes the potential for investors to take advantage of "stale" prices. These can occur, as one example, when funds own foreign securities whose prices close on overseas exchanges in different time zones. At the same time, we enhanced our monitoring of excessive trading. We did so by increasing our staff and updating our computer systems to improve our ability to detect excessive trading in our funds. Finally, we are supporting industry efforts to establish a "hard" 4 p.m. close on all trading, which would prevent the possibility of late trading. In March, MFS reached a second settlement with the SEC under an administrative proceeding resolving the SEC's investigation into how we disclosed brokerage allocation practices in connection with fund sales. According to the settlement order, we did not effectively disclose the potential conflict of interest that may arise from these arrangements. Under the terms of the settlement, MFS has agreed to pay one dollar in disgorgement and $50 million in penalty to MFS fund shareholders. The settlement noted that MFS had policies in place designed to obtain best execution of all trades of securities within MFS portfolios. This past November, MFS eliminated the above mentioned practice of directing brokerage commissions to certain firms in recognition of fund sales. Additionally, we announced in March that we would ban the use of soft dollars to acquire third-party securities research and market data. Soft dollars are permitted under federal securities laws. In fact, it is a common industry practice to use a portion of the brokerage commissions to pay for certain research and execution products and services that are provided to asset managers. MFS will now pay cash out of its own pocket for third-party research and market data. MFS continues to be financially strong, with more than U.S. $140 billion (as of 12/31/03) in assets under management, which continued to be stable during the first quarter of 2004. We also have the full support of our parent company, Sun Life Financial, an internationally diversified financial services firm that manages more than U.S. $269 billion (as of 12/31/03). We chose to settle these two proceedings with the SEC so we could concentrate on serving our fund shareholders. As Chief Investment Officer, my focus is on ensuring that our portfolio teams work closely together and take full advantage of all the resources available to them to deliver the best possible investment performance. As the inventor of the open-end mutual fund in America in 1924, MFS has a strong tradition and culture of innovation. By strengthening our business and governance practices, we believe we have an unprecedented opportunity to set a new standard in the mutual fund industry. As I look ahead, I do so with confidence. The collaboration among MFS employees, many of whom have worked at the firm for their entire careers, continues as we remain singularly dedicated to our clients. It has been our sincere privilege to serve you, and we thank you for the confidence that you have shown in MFS. Respectfully, /s/ Robert J. Manning Robert J.

The release of increasingly positive economic numbers as the period progressed, particularly with regard to corporate earnings and GDP (gross domestic product) growth, helped drive the equity rally. By late 2003, corporate capital spending, which had been weak for some time, had also begun to accelerate. Another driver of the equity rally, in our view, was the U.S. Federal Reserve Board's decision to leave interest rates at a four-decade low throughout the period. While energy prices rose late in the period, core inflation - excluding volatile food and energy prices - remained very low relative to historical averages. - ----------------------------------------------- TOP 5 SECTOR WEIGHTINGS AS OF 2/29/04 FINANCIAL SERVICES 20.9% - ----------------------------------------------- TECHNOLOGY 15.7% - ----------------------------------------------- HEALTH CARE 12.7% - ----------------------------------------------- CONSUMER STAPLES 8.0% - ----------------------------------------------- UTILITIES & COMMUNICATIONS 7.8% - ----------------------------------------------- The portfolio is actively managed, and current holdings may be different. - ----------------------------------------------- DETRACTORS FROM PERFORMANCE Stock selection in the health care and technology sectors plus the fund's cash position took away from the fund's relative performance for the period ended February 29, 2004. In health care, our position in large pharmaceutical company Wyeth significantly underperformed the broad market. We believe that Wyeth's stock price declined because of ongoing litigation over the company's diet drug, and disappointing results from some of the firm's new products. In contrast, we did not own Pfizer stock, which outperformed the broad market. Pfizer's stock rebounded from depressed levels during the period because of the company's future new product flow. Other health care stocks that detracted from performance were Tenet Healthcare and Cyberonics. Tenet continued to struggle with setbacks stemming from its Medicare billing practices that surfaced in 2003, leading its stock price to decline significantly during the period. Neurostimulator manufacturer Cyberonics, also in the health care sector, experienced delays in potential new product approval by the U.S. Food and Drug Administration. In our opinion, the company was distracted by the delays and, as a consequence, its core business deteriorated. Throughout the period, the fund maintained a small allocation to short-term cash equivalent securities, which are used to purchase new securities and to provide liquidity. When the stock market rose, that cash position detracted from fund performance relative to the fund's benchmark, the Standard & Poor's 500 Stock Index, which holds no cash position. The fund's two biggest disappointments in the technology sector were electronic software distributor Digital River and digital wireless communications maker QUALCOMM. We owned Digital River because we viewed the company as a leader in software distribution. In our opinion, the stock's performance was hurt by the company's disappointing earnings guidance issued for first quarter 2004. That announcement was somewhat surprising because it followed strong third- and fourth-quarter earnings gains in 2003. We did not own QUALCOMM and thus missed the company's strong performance that we attributed to the opportunities presented by the company's third generation (3G) wireless products. CONTRIBUTORS TO PERFORMANCE Stock selection in the financial services sector and in utilities and communications made solid contributions to relative fund returns. In our experience, financial stocks have historically tended to do well in an economic recovery; performance from the group throughout the reporting period was no exception. The standout among the fund's financial holdings was FleetBoston. Fleet's stock price rose sharply when Bank of America announced its $47 billion takeover bid for Fleet. The fund also received solid performance from insurer Ace Limited. The company saw its stock price rebound in the latter half of 2003 from depressed valuations earlier in the year. Later in 2003, the firm had several quarters when income from insurance premiums rose and its claims costs declined. The resulting revenue increases gave an added lift to the value of the company's stock. Wireless companies within the utilities and communications group generated strong returns during the period. A number of our wireless holdings were among the fund's top contributors, including Sprint Corporation PCS, Andrew Corporation, and AT&T Wireless. We believe results from the group were fuelled by a number of factors, including increased capital spending on the part of telecommunications companies and the possibility for industry consolidation. In our opinion, the wireless industry was generally so strong that even that group's suppliers, such as semiconductor manufacturer PMC Sierra and QUALCOMM, did well. Both PMC Sierra and AT&T Wireless outperformed the broad market and were sold when they reached our price targets. As noted earlier, the fund did not own QUALCOMM. Other stocks that contributed to relative performance included Altria (formerly Philip Morris) and CTI Molecular Imaging. In our view, Altria continued to benefit from decreased investor concerns about litigation against the company. CTI, which manufactures PET (positron emission tomography) scanners, rebounded from lows encountered in the third quarter of 2003. The fund's underweighting in Wal-Mart helped relative returns when the company underperformed the broad market. The fund sold its Wal-Mart holdings because of disappointing results. We avoided the poor performance from Merck stock, which we believe was adversely affected by potential patent challenges, competition from generic drug companies, and a weak pipeline of drugs in development.

INDEX DEFINITION STANDARD & POOR'S 500 STOCK INDEX - a commonly used measure of the broad U.S. stock market. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Class A results, including sales charge, reflects the deduction of the maximum 5.75% sales charge. Class B results, including sales charge, reflects the deduction of the applicable contingent deferred sales charge (CDSC), which declines over six years from 4% to 0%. Class C results, including sales charge, redeemed within one year from the end of the calendar month of purchase reflects the deduction of the 1% CDSC. Class I shares have no sales charges and are available only to certain investors. Class R1 and R2 shares have no sales charges and are available only to certain retirement plans. Performance for share classes offered after Class A shares includes the performance of the fund's Class A shares for periods prior to their offering. Blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the initial share class, and lower performance for share classes with lower operating expenses than the initial share class. Performance results reflect any applicable subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance would be less favorable. Please see the prospectus and financial statements for details.

See notes to financial statements. - ------------------------------------------------------------------------------ NOTES TO FINANCIAL STATEMENTS (unaudited) - ------------------------------------------------------------------------------ (1) BUSINESS AND ORGANIZATION MFS Research Growth and Income Fund (the fund) is a diversified series of MFS Series Trust I (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. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 fund 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 - The fund uses independent pricing services approved by the Board of Trustees wherever possible to value its portfolio securities. Portfolio securities are valued at current market prices where current market prices are readily available, or the fund may fair value portfolio securities under the direction of the Board of Trustees when a determination is made that current market prices are not readily available. Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Equity securities for which it is determined that current market prices are not readily available will be fair valued under the direction of the Board of Trustees. The fund may also fair value foreign equity securities in cases where closing market prices are not readily available or are deemed not reflective of readily available market prices. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the fund calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the fund may utilize information from an external vendor or other sources to adjust closing market prices of foreign equity securities to reflect what it believes to be the fair value of the securities as of the fund's valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with institutions that the fund's investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The fund requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. The fund 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 fund under each such repurchase agreement. The fund, 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 - 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. SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as lending agent, may loan the securities of the fund to certain qualified institutions (the "Borrowers") approved by the fund. 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 fund with indemnification against Borrower default. The fund bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or 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 fund and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the fund 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. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS - The fund 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 fund may enter into forward foreign currency exchange contracts for hedging purposes as well as for non-hedging purposes. For hedging purposes, the fund may enter into contracts to deliver or receive foreign currency it will receive from or require for its normal investment activities. The fund 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 fund may enter into contracts with the intent of changing the relative exposure of the fund'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 discount is amortized or accreted for financial statement purposes in accordance with accounting principles generally accepted in the United Sates of America. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. During the six months ended February 29, 2004, the fund's custodian fees were reduced by $316 under this arrangement. The fund has entered into a commission recapture agreement, under which certain brokers will credit the fund a portion of the commissions generated, to offset certain expenses of the fund. For the six months ended February 29, 2004, the fund's miscellaneous expenses were reduced by $1,008 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The fund'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 fund 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. Common types of book and tax differences that could occur include differences in accounting for currency transactions and capital losses. The tax character of distributions declared for the years ended August 31, 2003 and August 31, 2002 was as follows: 8/31/03 8/31/02 Distributions declared from: - ------------------------------------------------------------------------- Ordinary income $-- $-- - ------------------------------------------------------------------------- Long-term capital gain -- 3,148,446 - ------------------------------------------------------------------------- $-- $3,148,446 - ------------------------------------------------------------------------- Tax return of capital -- -- - ------------------------------------------------------------------------- Total distributions declared $-- $3,148,446 - ------------------------------------------------------------------------- The fund paid no distributions for the year ended August 31, 2003. As of August 31, 2003, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $-- - ------------------------------------------------------------------------- Undistributed long-term capital gain -- - ------------------------------------------------------------------------- Capital loss carryforward (24,066,551) - ------------------------------------------------------------------------- Unrealized appreciation 13,196,622 - ------------------------------------------------------------------------- Post-October capital loss deferral (2,824,860) - ------------------------------------------------------------------------- Other temporary differences (63,317) - ------------------------------------------------------------------------- Post-October capital loss deferrals represent losses realized during the current fiscal year, but recognized for tax purposes in the next fiscal year. For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on: EXPIRATION DATE August 31, 2010 $(8,969,653) - ------------------------------------------------------------------------- August 31, 2011 (15,096,898) - ------------------------------------------------------------------------- Total $(24,066,551) - ------------------------------------------------------------------------- MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple classes of shares, which differ in their respective distribution and service fees. All shareholders bear the common expenses of the fund based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. Class B shares will convert to Class A shares approximately eight years after purchase. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund 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 the following annual rates: First $500 million of average net assets 0.65% - -------------------------------------------------------------------------------- Average net assets in excess of $500 million 0.55% - -------------------------------------------------------------------------------- The fund pays compensation to the Independent Trustees ("Trustees") in the form of both a retainer and attendance fees, and pays no compensation directly to its Trustees who are officers of the investment adviser, or to officers of the fund, all of whom receive remuneration for their services to the fund from MFS. Certain officers and Trustees of the fund are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The fund has an unfunded defined benefit plan for retired Trustees and an unfunded retirement benefit deferral plan for current Trustees. Included in Trustees' compensation is a net decrease of $8,737 as a result of the change in the fund's pension liability for current Trustees and a pension expense of $15,437 for retired Trustees for the six months ended February 29, 2004. ADMINISTRATOR - The fund has an administrative services agreement with MFS to provide the fund with certain financial, legal, shareholder communications, compliance, and other administrative services. As a partial reimbursement for the cost of providing these services, the fund pays MFS an administrative fee up to the following annual percentage rates of the fund'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% ---------------------------------------------------------- In addition to the administrative services provided by MFS to the fund as described above, MFS is responsible for providing certain administrative services with respect to Class R2 shares. These services include various administrative, recordkeeping, and communication/educational services with respect to the retirement plans which invest in Class R2 shares, and may be provided directly by MFS or by a third party. The fund pays an annual 0.25% administrative service fee solely from the assets of Class R2 shares to MFS for the provision of these services. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, as distributor, received $14,027 for the six months ended February 29, 2004, as its portion of the sales charge on sales of Class A shares of the fund. The Trustees have adopted a distribution plan for Class A, Class B, Class C, Class R1, and Class R2 shares pursuant to rule 12b-1 of the Investment Company Act of 1940 as follows: The fund's distribution plan provides that the fund will pay MFD an annual percentage of its average daily net assets attributable to certain share classes in order that MFD may pay expenses on behalf of the fund related to the distribution and servicing of its shares. These expenses include a service fee paid to each securities dealer that enters into a sales agreement with MFD based on the average daily net assets of accounts attributable to such dealers. The fees are calculated based on each class' average daily net assets. The maximum distribution and service fees for each class of shares are as follows: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Distribution Fee 0.10% 0.75% 0.75% 0.25% 0.25% - -------------------------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% 0.25% 0.25% - -------------------------------------------------------------------------------------------------------------------- Total Distribution Plan 0.35% 1.00% 1.00% 0.50% 0.50% - -------------------------------------------------------------------------------------------------------------------- MFD retains the service fee for accounts not attributable to a securities dealer, which for the six months ended February 29, 2004 amounted to: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Service Fee Retained by MFD $1,184 $394 $135 $-- $-- - -------------------------------------------------------------------------------------------------------------------- Fees incurred under the distribution plan during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Effective Annual Percentage Rates 0.35% 1.00% 1.00% 0.50% 0.50% - -------------------------------------------------------------------------------------------------------------------- Certain Class A and Class C shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within, for Class A shares, 12 months following the purchase, and, for Class C shares, the first year from the end of the calendar month of purchase. A contingent deferred sales charge is imposed on shareholder redemptions of Class B shares in the event of a shareholder redemption within six years from the end of the calendar month of purchase. MFD receives all contingent deferred sales charges. Contingent deferred sales charges imposed during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C Contingent Deferred Sales Charges Imposed $862 $69,271 $455 - ----------------------------------------------------------------------------------------------------------- SHAREHOLDER SERVICING AGENT - Included in shareholder servicing costs is a fee paid to MFSC, a wholly owned subsidiary of MFS, for its services as shareholder servicing agent. The fee is calculated as a percentage of the fund's average daily net assets at an annual rate of 0.11%, which amounted to $97,378 for the six months ended February 29, 2004. Also included in shareholder servicing costs are out-of-pocket expenses, paid to MFSC, which amounted to $14,277 for the six months ended February 29, 2004, as well as other expenses paid to unaffiliated vendors. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $98,142,888 and $88,789,136, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the fund, as computed on a federal income tax basis, are as follows: Aggregate cost $164,925,345 --------------------------------------------------------- Gross unrealized appreciation $24,227,838 --------------------------------------------------------- Gross unrealized depreciation (2,290,064) --------------------------------------------------------- Net unrealized appreciation $21,937,774 --------------------------------------------------------- (5) SHARES OF BENEFICIAL INTEREST The fund's Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest.

(6) LINE OF CREDIT The fund and other affiliated funds participate in an $800 million 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 plus 0.50%. In addition, a commitment fee, based on the average daily unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the fund for the six months ended February 29, 2004 was $533. The fund had no borrowings during the six months ended February 29, 2004. (7) LEGAL PROCEEDINGS On March 31, 2004, MFS settled an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. Under the terms of the settlement, in which MFS neither admitted nor denied any wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50 million in penalty to certain MFS funds, pursuant to a plan to be approved by an independent distribution consultant. The agreement with the SEC is reflected in an order of the SEC. The settlement order states that MFS failed to adequately disclose to the Boards of Trustees and to shareholders of the MFS funds the specifics of its preferred arrangements with certain brokerage firms selling MFS fund shares. The settlement order states that MFS had in place policies designed to obtain best execution of all fund trades. As part of the settlement, MFS also agreed to retain an independent compliance consultant to review the completeness of its disclosure to fund trustees and to fund shareholders of strategic alliances between MFS or its affiliates and broker-dealers and other financial advisers who support the sale of fund shares. The brokerage allocation practices which were the subject of this proceeding were discontinued by MFS in November 2003. In addition, in February, 2004, MFS reached agreement with the Securities and Exchange Commission ("SEC"), the New York Attorney General ("NYAG") and the Bureau of Securities Regulation of the State of New Hampshire ("NH") to settle administrative proceedings alleging false and misleading information in certain MFS fund prospectuses regarding market timing and related matters (the "February Settlements"). These regulators alleged that prospectus language for certain MFS funds was false and misleading because, although the prospectuses for those funds in the regulators' view indicated that the funds prohibited market timing, MFS did not limit trading activity in 11 domestic large cap stock, high grade bond and money market funds. MFS' former Chief Executive Officer, John W. Ballen, and former President, Kevin R. Parke, have also reached agreement with the SEC (Messrs. Ballen and Parke resigned their director and officer positions with MFS on February 13, 2004). Under the terms of the February Settlements, MFS and the executives neither admit nor deny wrongdoing. Under the terms of the February Settlements, a $225 million pool has been established for distribution to shareholders in certain of the MFS funds offered to retail investors ("Retail Funds"), which has been funded by MFS and of which $50 million is characterized as a penalty. This pool will be distributed in accordance with a methodology developed by an independent distribution consultant in consultation with MFS and the Boards of Trustees of the Retail Funds, and acceptable to the SEC. MFS has further agreed with the NYAG to reduce its management fees in the aggregate amount of approximately $25 million annually over the next five years, and not to increase certain management fees during this period. MFS has also paid an administrative fine to NH in the amount of $1 million, which will be used for investor education purposes (NH will retain $250,000 and $750,000 will be contributed to the North American Securities Administrators Association's Investor Protection Trust). In addition, MFS and the Retail Funds will adopt certain governance changes. Messrs. Ballen and Parke have agreed to temporary suspensions from association with any registered investment company or investment adviser, will pay approximately $315,000 each to the SEC, and resigned their positions as trustees of all MFS funds, and Mr. Ballen resigned his position as President of all MFS funds, effective February 6, 2004. Messrs. Ballen and Parke will not be returning to MFS or the MFS funds after their suspensions. Since December 2003, MFS, Sun Life Financial Inc., various MFS funds, the Trustees of these MFS funds, and certain officers of MFS have been named as defendants in multiple lawsuits filed in federal and state courts. The lawsuits variously have been commenced as class actions or individual actions on behalf of investors who purchased, held or redeemed shares of the funds during specified periods, as class actions on behalf of participants in certain retirement plan accounts, or as derivative actions on behalf of the MFS funds. The lawsuits generally allege that some or all of the defendants (i) permitted or acquiesced in market timing and/or late trading in some of the MFS funds, inadequately disclosed MFS' internal policies concerning market timing and such matters, and received excessive compensation as fiduciaries to the MFS fund, or (ii) permitted or acquiesced in the improper use of fund assets by MFS to support the distribution of fund shares and inadequately disclosed MFS' use of fund assets in this manner. The actions assert that some or all of the defendants violated the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of 1940 and the Investment Advisers Act of 1940, the Employee Retirement Income Security Act of 1974, as well as fiduciary duties and other violations of common law. The lawsuits seek unspecified compensatory damages. Insofar as any of the actions is appropriately brought derivatively on behalf of any of the MFS funds, any recovery will inure to the benefit of the funds. The defendants are reviewing the allegations of the multiple complaints and will respond appropriately. Additional lawsuits based on similar allegations may be filed in the future. Any potential resolution of these matters may include, but not be limited to, judgments or settlements for damages against MFS, the MFS funds, or any other named defendant. As noted above, as part of the regulatory settlements, MFS has established a restitution pool in the amount of $225 million to compensate certain shareholders of the Retail Funds for damages that they allegedly sustained as a result of market timing or late trading in certain of the funds, and will pay $50 million to compensate certain MFS funds based upon the amount of brokerage commissions allocated in recognition of fund sales. It is not clear whether these amounts will be sufficient to compensate shareholders for all of the damage they allegedly sustained, whether certain shareholders or putative class members may have additional claims to compensation, or whether the damages that may be awarded in any of the actions will exceed these amounts. In the event the MFS funds incur any losses, costs or expenses in connection with such lawsuits, the Boards of Trustees of the affected funds may pursue claims on behalf of such funds against any party that may have liability to the funds in respect thereof. Review of these matters by the independent Trustees of the MFS funds and their counsel is continuing. There can be no assurance that these regulatory actions and lawsuits, or the adverse publicity associated with these developments will not result in increased fund redemptions, reduced sales of fund shares, or other adverse consequences to the funds. - -------------------------------------------------------------------------------------------------------------- TRUSTEES AND OFFICERS - -------------------------------------------------------------------------------------------------------------- The following tables present certain information regarding the Trustees and officers of MFS Series Trust I, of which the fund is a series, including their principal occupations, which, unless specific dates are shown, are of more than five years' duration, although the titles may not have been the same throughout.

Manning] As the firm's new Chief Executive Officer, I want to thank you for your continued trust in MFS and tell you about the series of actions we have taken since our recent settlements with the regulators. These actions are designed to enhance the governance structure of the MFS funds, tighten our business practices, and strengthen the management team at MFS. In early February, Robert Pozen joined MFS as non-executive Chairman. A seasoned veteran of the mutual fund industry, Bob has held prior positions as President of Fidelity Management & Research Company, as Associate General Counsel of the Securities and Exchange Commission, and as a visiting professor at Harvard Law School. In an effort to develop and implement policies that we believe will set a new standard in regulatory compliance, MFS has hired two new senior executives. Jeffrey Carp is joining us as General Counsel with responsibility for all of our legal affairs. Previously he was a senior partner with the law firm of Hale and Dorr LLP. Also joining MFS in the new position of Executive Vice President of Regulatory Affairs is Maria Dwyer, who returned to the firm after serving as a senior executive at Fidelity. At MFS, Maria is in charge of compliance, internal audit, and fund treasury. In the area of governance, we have taken steps to enhance the independence of our funds' boards of trustees to better protect the interests of shareholders. We have independent board chairs and at least 75% of the trustees are independent. The trustees will appoint not only their own counsel but also an independent compliance officer. This officer will assist the boards and their committees in monitoring the MFS funds' compliance with federal and state regulations. In February, MFS reached agreements with federal and state regulators to settle their administrative proceedings against the firm and two senior executives in connection with market timing and related issues. Under the terms of the settlements, we agreed to pay $225 million to compensate affected retail fund shareholders. The $225 million will be distributed in accordance with a distribution plan developed by an independent consultant. We have further agreed with state regulators to reduce management fees on certain funds we advise by approximately $25 million annually over the next five years and to pay an administrative fine of $1 million, which will be used for the purpose of investor education. We have introduced a set of policies designed to protect the MFS funds and MFS fund shareholders from market timing abuses. By July, all MFS retail funds, except money market funds, will have a 2% redemption fee on short-term trades. Our global, international, high-yield, mid- and small-cap funds will impose the 2% fee on redemptions or exchanges of fund shares made within 30 calendar days of a share purchase. For all other MFS funds, except money market funds, the 2% fee will be imposed on redemptions or exchanges made within 5 business days of a share purchase. See the fund prospectus for more information. We continue to use fair value pricing, a strategy that minimizes the potential for investors to take advantage of "stale" prices. These can occur, as one example, when funds own foreign securities whose prices close on overseas exchanges in different time zones. At the same time, we enhanced our monitoring of excessive trading. We did so by increasing our staff and updating our computer systems to improve our ability to detect excessive trading in our funds. Finally, we are supporting industry efforts to establish a "hard" 4 p.m. close on all trading, which would prevent the possibility of late trading. In March, MFS reached a second settlement with the SEC under an administrative proceeding resolving the SEC's investigation into how we disclosed brokerage allocation practices in connection with fund sales. According to the settlement order, we did not effectively disclose the potential conflict of interest that may arise from these arrangements. Under the terms of the settlement, MFS has agreed to pay one dollar in disgorgement and $50 million in penalty to MFS fund shareholders. The settlement noted that MFS had policies in place designed to obtain best execution of all trades of securities within MFS portfolios. This past November, MFS eliminated the above mentioned practice of directing brokerage commissions to certain firms in recognition of fund sales. Additionally, we announced in March that we would ban the use of soft dollars to acquire third-party securities research and market data. Soft dollars are permitted under federal securities laws. In fact, it is a common industry practice to use a portion of the brokerage commissions to pay for certain research and execution products and services that are provided to asset managers. MFS will now pay cash out of its own pocket for third-party research and market data. MFS continues to be financially strong, with more than U.S. $140 billion (as of 12/31/03) in assets under management, which continued to be stable during the first quarter of 2004. We also have the full support of our parent company, Sun Life Financial, an internationally diversified financial services firm that manages more than U.S. $269 billion (as of 12/31/03). We chose to settle these two proceedings with the SEC so we could concentrate on serving our fund shareholders. As Chief Investment Officer, my focus is on ensuring that our portfolio teams work closely together and take full advantage of all the resources available to them to deliver the best possible investment performance. As the inventor of the open-end mutual fund in America in 1924, MFS has a strong tradition and culture of innovation. By strengthening our business and governance practices, we believe we have an unprecedented opportunity to set a new standard in the mutual fund industry. As I look ahead, I do so with confidence. The collaboration among MFS employees, many of whom have worked at the firm for their entire careers, continues as we remain singularly dedicated to our clients. It has been our sincere privilege to serve you, and we thank you for the confidence that you have shown in MFS. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer MFS Investment Management(R) March 15, 2004 Note to Shareholders: On February 6, 2004, Jeffrey L. Shames retired as Chairman of MFS. Robert Pozen was named as non-executive Chairman. Also, on February 6, 2004, Robert J. Manning was appointed Chief Executive Officer, President, and Chief Investment Officer. The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed. - ------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - ------------------------------------------------------------------------------- THE MFS(R) DIFFERENCE For 80 years MFS has been offering investors clear paths to pursuing specific investment objectives. Today, millions of individuals and thousands of institutions all over the world look to MFS to manage their assets with insight and care. Our success, we believe, has to do with the fact that we see investors as people with plans, not just dollars to invest. When you invest with MFS, you invest with a company dedicated to helping you realize your long-term financial goals. INVESTORS CHOOSE MFS FOR OUR o global asset management expertise across all asset classes o time-tested money management process for pursuing consistent results o full spectrum of investment products backed by MFS Original Research(R) o resources and services that match real-life needs TURNING INFORMATION INTO OPPORTUNITY Sound investments begin with sound information. MFS has been doing its own research and analyzing findings in-house for decades. The process we use to uncover opportunity is called MFS Original Research(R). MFS ORIGINAL RESEARCH INVOLVES: o meeting with the management of 3,000 companies each year to assess their business plans and the managers' ability to execute those plans o making onsite visits to more than 2,000 companies annually to gain first-hand knowledge of their operations and products o analyzing financial statements and balance sheets o talking extensively with companies' customers and competitors o developing our own proprietary estimates of companies' earnings - ------------------------------------------------------------------------------- MANAGEMENT REVIEW - ------------------------------------------------------------------------------- MARKET ENVIRONMENT The turnaround in global stock markets that began in the spring of 2003 continued for most of the six-month period ended February 29, 2004. The release of increasingly positive economic numbers as the period progressed, particularly with regard to corporate earnings and GDP (gross domestic product) growth, helped drive the equity rally. By late 2003, corporate capital spending, which had been weak for some time, had also begun to accelerate. Another driver of the equity rally, in our view, was the U.S. Federal Reserve Board's decision to leave interest rates at a four-decade low throughout the period. While energy prices rose late in the period, core inflation - excluding volatile food and energy prices - remained very low relative to historical averages. - ----------------------------------------------- TOP 5 SECTOR WEIGHTINGS AS OF 2/29/04 TECHNOLOGY 39.4% - ----------------------------------------------- HEALTH CARE 18.4% - ----------------------------------------------- SPECIAL PRODUCTS AND SERVICES 14.7% - ----------------------------------------------- RETAILING 8.3% - ----------------------------------------------- FINANCIAL SERVICES 5.3% - ----------------------------------------------- The portfolio is actively managed, and current weightings may be different. - ----------------------------------------------- DETRACTORS FROM PERFORMANCE Over the six-month period ended February 29, 2004, the fund underperformed its benchmark, the Russell 2000 Growth Index, and the average small-cap growth fund as reported by Lipper Inc. Relative to our benchmark, technology was the fund's weakest area over the period. Stock selection as well as an overweighting in the sector hurt results as the sector underperformed the broad market. Our shares in GlobespanVirata, a maker of semiconductor chips for telecommunications equipment, fell in price after the firm lowered earnings expectations in the face of strong competition and pricing pressure. We subsequently sold our position in the firm. Similarly, our stock in Zarlink Semiconductor, another supplier to the telecommunications industry, traded lower after the company lowered projections for first-quarter 2004 sales. The fund's holding in DVD software company InterVideo dropped in price after InterVideo's main competitor announced it would give away DVD software in hopes of motivating consumers to upgrade to a paid version later. Other technology positions that lost value over the period included human resources and payroll software firm Kronos and e-commerce outsourcing company Digital River. Stock selection in the health care sector also held back performance. The major detractors in the sector were biopharmaceutical firm XOMA and Advisory Board, a provider of best practices research and analysis to the health care industry. Stock selection in the leisure sector also detracted from performance. Going into the period, we believed our positions in advertising-sensitive broadcasting stocks would benefit from increased ad spending as the U.S. economy recovered. However, advertising spending, particularly in local markets, stagnated somewhat during the period. Fund positions such as Entercom Communications and Cox Radio lost value. Elsewhere in the sector, our position in educational toy maker LeapFrog Enterprises fell after the company reported weak sales growth that hurt third-quarter 2003 earnings. LeapFrog was later sold from the portfolio. (LeapFrog, Entercom, and Cox, however, were not among the fund's top detractors for the period.) The fund's cash position, while it averaged less than 3% of assets over the period, also detracted from relative performance. In a period when equity markets rose sharply, cash hurt performance against our benchmark, the Russell 2000 Growth Index, which has no cash position. CONTRIBUTORS TO PERFORMANCE Stock selection in the utilities and communications sector was positive for performance. Andrew Corporation, a supplier of infrastructure products to wireless communications firms, was the key contributor in the sector. We believe the firm's strong performance was driven by increased capital spending in the wireless industry as a whole. In the autos and housing sector, stock selection as well as an underweighting in the sector were modestly beneficial for performance as the sector underperformed the broad market. While overall stock selection in technology detracted from results, a number of technology stocks were among the fund's top relative performers over the period. These included software firm Open Text, Internet networking products firm F5 Networks, online education firm eCollege.com, network security firm NetScreen Technologies, and semiconductor company PMC-Sierra. All of these stocks outperformed the broad market over the period. NetScreen Technologies was sold when a takeover bid was launched for the company, and the stock reached our price target. In the financial services area, our position in Friedman, Billings, Ramsey Group, a provider of investment banking and asset management services, benefited from its exposure to an improving equity market. Another strong contributor to performance was our holding in medical equipment firm Nektar Therapeutics. Respectfully, /s/ Robert A. Henderson /s/ Donald F. Pitcher, Jr. Robert A. Henderson Donald F.

INDEX DEFINITION RUSSELL 2000 GROWTH INDEX - measures the performance of U.S. small-cap growth stocks. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Class A and 529A results, including sales charge, reflects the deduction of the maximum 5.75% sales charge. Class B and 529B results, including sales charge, reflects the deduction of the applicable contingent deferred sales charge (CDSC), which declines over six years from 4% to 0%. Class C and 529C results, including sales charge, redeemed within one year from the end of the calendar month of purchase reflects the deduction of the 1% CDSC. Class I shares have no sales charges and are available only to certain investors. Class R1 and R2 shares have no sales charges and are available only to certain retirement plans. Class 529A, 529B, and 529C shares are only available in conjunction with qualified tuition programs, such as the MFS 529 Savings Plan. Performance for share classes offered after class A shares includes the performance of the fund's class A shares for periods prior to their offering. Blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the initial share class, and lower performance for share classes with lower operating expenses than the initial share class. Performance results reflect any applicable 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. KEY RISK CONSIDERATIONS Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. Investing in small and/or emerging growth companies is riskier than investing in more-established companies. These risks may increase share price volatility. Please see the prospectus for further information regarding these and other risk considerations. This report is prepared for the general information of shareholders. It is authorized for distribution to prospective investors only when preceded or accompanied by a current prospectus. - -------------------------------------------------------------------------------------------- PORTFOLIO OF INVESTMENTS (unaudited) - 2/29/04 - -------------------------------------------------------------------------------------------- The Portfolio of Investments is a complete list of all securities owned by your fund.

See notes to financial statements. - ------------------------------------------------------------------------------ NOTES TO FINANCIAL STATEMENTS (unaudited) - ------------------------------------------------------------------------------ (1) BUSINESS AND ORGANIZATION MFS New Discovery Fund (the fund) is a diversified series of MFS Series Trust I (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. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 fund 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 - The fund uses independent pricing services approved by the Board of Trustees wherever possible to value its portfolio securities. Portfolio securities are valued at current market prices where current market prices are readily available, or the fund may fair value portfolio securities under the direction of the Board of Trustees when a determination is made that current market prices are not readily available. Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Equity securities for which it is determined that current market prices are not readily available will be fair valued under the direction of the Board of Trustees. The fund may also fair value foreign equity securities in cases where closing market prices are not readily available or are deemed not reflective of readily available market prices. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the fund calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the fund may utilize information from an external vendor or other sources to adjust closing market prices of foreign equity securities to reflect what it believes to be the fair value of the securities as of the fund's valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with institutions that the fund's investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The fund requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. The fund 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 fund under each such repurchase agreement. The fund, 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 - 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. SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as lending agent, may loan the securities of the fund to certain qualified institutions (the "Borrowers") approved by the fund. 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 fund with indemnification against Borrower default. The fund bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or 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 fund and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the fund and the lending agent. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with accounting principles generally accepted in the United States of America. All discount is accreted for 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. FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. This amount, for the six months ended February 29, 2004, is shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The fund'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 fund 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. Common types of book and tax differences that could occur include differences in accounting for currency transactions. The tax character of distributions declared for the years ended August 31, 2003 and August 31, 2002 was as follows: 8/31/03 8/31/02 Distributions declared from: - ------------------------------------------------------------------------------ Ordinary income $-- $23,344 - ------------------------------------------------------------------------------ The fund paid no distributions for the year ended August 31, 2003. As of August 31, 2003, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Capital loss carryforward $(625,043,618) --------------------------------------------------------- Post-October capital loss deferral (4,559,698) --------------------------------------------------------- Unrealized appreciation 257,619,886 --------------------------------------------------------- Other temporary differences (14,627) --------------------------------------------------------- For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on August 31, 2010, ($271,036,016) and August 31, 2011, ($354,007,602). MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple classes of shares, which differ in their respective distribution and service fees. All shareholders bear the common expenses of the fund based on daily net assets of each class, without distinction between share classes. 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 529B shares will convert to Class A and Class 529A shares, respectively approximately eight years after purchase. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund 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 0.90% of the fund's average daily net assets. The investment adviser has contractually agreed to reduce its management fee to 0.85% of the fund's average daily net assets in excess of $3 billion. This contractual waiver may be rescinded by MFS only with the approval of the fund's Board of Trustees. The fund pays compensation to the Independent Trustees ("Trustees") in the form of both a retainer and attendance fees, and pays no compensation directly to its Trustees who are officers of the investment adviser, or to officers of the fund, all of whom receive remuneration for their services to the fund from MFS. Certain officers and Trustees of the fund are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The fund has an unfunded, defined benefit plan for retired Trustees. Included in Trustees' compensation is a pension expense of $619 for retired Trustees for the six months ended February 29, 2004. ADMINISTRATOR - The fund has an administrative services agreement with MFS to provide the fund with certain financial, legal, shareholder communications, compliance, and other administrative services. As a partial reimbursement for the cost of providing these services, the fund pays MFS an administrative fee up to the following annual percentage rates of the fund'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% ---------------------------------------------------------- In addition to the administrative services provided by MFS to the fund as described above, MFS is responsible for providing certain administrative services with respect to Class R2 shares. These services include various administrative, recordkeeping, and communication/educational services with respect to the retirement plans which invest in Class R2 shares, and may be provided directly by MFS or by a third party. The fund pays an annual 0.25% administrative service fee solely from the assets of Class R2 shares to MFS for the provision of these services. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, as distributor, received $65,963 and $735 for the six months ended February 29, 2004 as its portion of the sales charge on sales of Class A and Class 529A shares of the fund, respectively. The Trustees have adopted a distribution plan for Class A, Class B, Class C, Class R1, Class R2, Class 529A, Class 529B and Class 529C shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as follows: The fund's distribution plan provides that the fund will pay MFD an annual percentage of its average daily net assets attributable to certain share classes in order that MFD may pay expenses on behalf of the fund related to the distribution and servicing of its shares. These expenses include a service fee paid to each securities dealer that enters into a sales agreement with MFD based on the average daily net assets of accounts attributable to such dealers. These fees are calculated based on each class' average daily net assets. The maximum distribution and service fees for each class of shares are as follows: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Distribution Fee 0.10% 0.75% 0.75% 0.25% 0.25% - ----------------------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% 0.25% 0.25% - ----------------------------------------------------------------------------------------------------------------- Total Distribution Plan 0.35% 1.00% 1.00% 0.50% 0.50% - ----------------------------------------------------------------------------------------------------------------- CLASS 529A CLASS 529B CLASS 529C Distribution Fee 0.25% 0.75% 0.75% - ----------------------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% - ----------------------------------------------------------------------------------------------------------------- Total Distribution Plan 0.50% 1.00% 1.00% - ----------------------------------------------------------------------------------------------------------------- MFD retains the service fee for accounts not attributable to a securities dealer, which for the six months ended February 29, 2004, amounted to: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Service Fee Retained by MFD $24,773 $1,652 $847 $-- $-- - ----------------------------------------------------------------------------------------------------------------- CLASS 529A CLASS 529B CLASS 529C Service Fee Retained by MFD $77 $6 $25 - ----------------------------------------------------------------------------------------------------------------- Fees incurred under the distribution plan during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Effective Annual Percentage Rates 0.35% 1.00% 1.00% 0.50% 0.50% - ----------------------------------------------------------------------------------------------------------------- CLASS 529A CLASS 529B CLASS 529C Effective Annual Percentage Rates 0.35% 1.00% 1.00% - ----------------------------------------------------------------------------------------------------------------- Payment of the 0.15% per annum portion of the Class 529A distribution fee that is not currently being charged will be implemented on such a date as the Trustees of the Trust may determine. Certain Class A, Class C and Class 529C shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within, for class A shares, 12 months following the purchase, and, for class C and 529C shares, the first year from the end of the calendar month of purchase. A contingent deferred sales charge is imposed on shareholder redemptions of Class B and Class 529B shares in the event of a shareholder redemption within six years from the end of the calendar month of purchase. MFD receives all contingent deferred sales charges. Contingent deferred sales charges imposed during the six months ended February 29, 2004 were as follows: CLASS A CLASS B CLASS C CLASS 529BCLASS 529C Contingent Deferred Sales Charges Imposed $17,348 $221,140 $4,513 $20 $-- - -------------------------------------------------------------------------------- The fund has and may from time to time enter into contracts with program managers and other parties which administer the tuition programs through which an investment in the fund's 529 share classes is made. The fund has entered into an agreement with MFD pursuant to which MFD receives an annual fee of up to 0.35% from the fund based solely upon the value of the fund's 529 share classes attributable to tuition programs to which MFD or a third party which contracts with MFD provides administrative services. The current fee has been established at 0.25% annually of average net assets of the fund's 529 share classes attributable to such programs. The fee may only be increased with the approval of the Board of Trustees that oversees the fund. The services provided by MFD or a third party with which MFD contracts include recordkeeping and tax reporting and account services, as well as services designed to maintain the program's compliance with the Internal Revenue Code and other regulatory requirements. SHAREHOLDER SERVICING AGENT - Included in shareholder servicing costs is a fee paid to MFSC, a wholly owned subsidiary of MFS, for its services as shareholder servicing agent. The fee is calculated as a percentage of the fund's average daily net assets at an annual rate of 0.11%, which amounted to $863,958 for the six months ended February 29, 2004. Also included in shareholder servicing costs are out-of-pocket expenses, paid to MFSC, which amounted to $427,599 for the six months ended February 29, 2004, as well as other expenses paid to unaffiliated vendors. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $826,488,380 and $732,142,203, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the fund, as computed on a federal income tax basis, are as follows: Aggregate cost $1,737,903,183 - -------------------------------------------------------------------------------- Gross unrealized appreciation $319,620,355 - -------------------------------------------------------------------------------- Gross unrealized depreciation (55,864,876) - -------------------------------------------------------------------------------- Net unrealized appreciation $263,755,479 - -------------------------------------------------------------------------------- (5) SHARES OF BENEFICIAL INTEREST The fund's Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest.

(6) LINE OF CREDIT The fund and other affiliated funds participate in an $800 million 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 plus 0.50%. In addition, a commitment fee, based on the average daily unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the fund for the six months ended February 29, 2004, was $5,514. The fund had no borrowings during the period. (7) RESTRICTED SECURITIES The fund may invest not more than 15% of its total assets in securities which are subject to legal or contractual restrictions on resale. At February 29, 2004, the fund owned the following restricted securities, excluding securities issued under Rule 144A, constituting 0.25% of net assets which may not be publicly sold without registration under the Securities Act of 1933. The fund does not have the right to demand that such securities be registered. The value of these securities is determined by valuations furnished by dealers or by a pricing service, or if not available, in good faith at the direction of the Trustees. DATE OF DESCRIPTION ACQUISITION SHARES COST VALUE Conceptus, Inc. 2/25/04 425,000 $3,612,500 $3,545,775 - -------------------------------------------------------------------------------- Cryolife, Inc. 1/22/04 119,500 746,875 688,320 - -------------------------------------------------------------------------------- $4,234,095 - -------------------------------------------------------------------------------- (8) LEGAL PROCEEDINGS On March 31, 2004, MFS settled an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. Under the terms of the settlement, in which MFS neither admitted nor denied any wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50 million in penalty to certain MFS funds, pursuant to a plan to be approved by an independent distribution consultant. The agreement with the SEC is reflected in an order of the SEC. The settlement order states that MFS failed to adequately disclose to the Boards of Trustees and to shareholders of the MFS funds the specifics of its preferred arrangements with certain brokerage firms selling MFS fund shares. The settlement order states that MFS had in place policies designed to obtain best execution of all fund trades. As part of the settlement, MFS also agreed to retain an independent compliance consultant to review the completeness of its disclosure to fund trustees and to fund shareholders of strategic alliances between MFS or its affiliates and broker-dealers and other financial advisers who support the sale of fund shares. The brokerage allocation practices which were the subject of this proceeding were discontinued by MFS in November 2003. In addition, in February, 2004, MFS reached agreement with the Securities and Exchange Commission ("SEC"), the New York Attorney General ("NYAG") and the Bureau of Securities Regulation of the State of New Hampshire ("NH") to settle administrative proceedings alleging false and misleading information in certain MFS fund prospectuses regarding market timing and related matters (the "February Settlements"). These regulators alleged that prospectus language for certain MFS funds was false and misleading because, although the prospectuses for those funds in the regulators' view indicated that the funds prohibited market timing, MFS did not limit trading activity in 11 domestic large cap stock, high grade bond and money market funds. MFS' former Chief Executive Officer, John W. Ballen, and former President, Kevin R. Parke, have also reached agreement with the SEC (Messrs. Ballen and Parke resigned their director and officer positions with MFS on February 13, 2004). Under the terms of the February Settlements, MFS and the executives neither admit nor deny wrongdoing. Under the terms of the February Settlements, a $225 million pool has been established for distribution to shareholders in certain of the MFS funds offered to retail investors ("Retail Funds"), which has been funded by MFS and of which $50 million is characterized as a penalty. This pool will be distributed in accordance with a methodology developed by an independent distribution consultant in consultation with MFS and the Boards of Trustees of the Retail Funds, and acceptable to the SEC. MFS has further agreed with the NYAG to reduce its management fees in the aggregate amount of approximately $25 million annually over the next five years, and not to increase certain management fees during this period. MFS has also paid an administrative fine to NH in the amount of $1 million, which will be used for investor education purposes (NH will retain $250,000 and $750,000 will be contributed to the North American Securities Administrators Association's Investor Protection Trust). In addition, MFS and the Retail Funds will adopt certain governance changes. Messrs. Ballen and Parke have agreed to temporary suspensions from association with any registered investment company or investment adviser, will pay approximately $315,000 each to the SEC, and resigned their positions as trustees of all MFS funds, and Mr. Ballen resigned his position as President of all MFS funds, effective February 6, 2004. Messrs. Ballen and Parke will not be returning to MFS or the MFS funds after their suspensions. Since December 2003, MFS, Sun Life Financial Inc., various MFS funds, the Trustees of these MFS funds, and certain officers of MFS have been named as defendants in multiple lawsuits filed in federal and state courts. The lawsuits variously have been commenced as class actions or individual actions on behalf of investors who purchased, held or redeemed shares of the funds during specified periods, as class actions on behalf of participants in certain retirement plan accounts, or as derivative actions on behalf of the MFS funds. The lawsuits generally allege that some or all of the defendants (i) permitted or acquiesced in market timing and/or late trading in some of the MFS funds, inadequately disclosed MFS' internal policies concerning market timing and such matters, and received excessive compensation as fiduciaries to the MFS fund, or (ii) permitted or acquiesced in the improper use of fund assets by MFS to support the distribution of fund shares and inadequately disclosed MFS' use of fund assets in this manner. The actions assert that some or all of the defendants violated the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of 1940 and the Investment Advisers Act of 1940, the Employee Retirement Income Security Act of 1974, as well as fiduciary duties and other violations of common law. The lawsuits seek unspecified compensatory damages. Insofar as any of the actions is appropriately brought derivatively on behalf of any of the MFS funds, any recovery will inure to the benefit of the funds. The defendants are reviewing the allegations of the multiple complaints and will respond appropriately. Additional lawsuits based on similar allegations may be filed in the future. Any potential resolution of these matters may include, but not be limited to, judgments or settlements for damages against MFS, the MFS funds, or any other named defendant. As noted above, as part of the regulatory settlements, MFS has established a restitution pool in the amount of $225 million to compensate certain shareholders of the Retail Funds for damages that they allegedly sustained as a result of market timing or late trading in certain of the funds, and will pay $50 million to compensate certain MFS funds based upon the amount of brokerage commissions allocated in recognition of fund sales. It is not clear whether these amounts will be sufficient to compensate shareholders for all of the damage they allegedly sustained, whether certain shareholders or putative class members may have additional claims to compensation, or whether the damages that may be awarded in any of the actions will exceed these amounts. In the event the MFS funds incur any losses, costs or expenses in connection with such lawsuits, the Boards of Trustees of the affected funds may pursue claims on behalf of such funds against any party that may have liability to the funds in respect thereof. Review of these matters by the independent Trustees of the MFS funds and their counsel is continuing. There can be no assurance that these regulatory actions and lawsuits, or the adverse publicity associated with these developments will not result in increased fund redemptions, reduced sales of fund shares, or other adverse consequences to the funds. - -------------------------------------------------------------------------------------------------------------- TRUSTEES AND OFFICERS - -------------------------------------------------------------------------------------------------------------- The following tables present certain information regarding the Trustees and officers of MFS Series Trust I, of which the fund is a series, including their principal occupations, which, unless specific dates are shown, are of more than five years' duration, although the titles may not have been the same throughout.

Manning] As the firm's new Chief Executive Officer, I want to thank you for your continued trust in MFS and tell you about the series of actions we have taken since our recent settlements with the regulators. These actions are designed to enhance the governance structure of the MFS funds, tighten our business practices, and strengthen the management team at MFS. In early February, Robert Pozen joined MFS as non-executive Chairman. A seasoned veteran of the mutual fund industry, Bob has held prior positions as President of Fidelity Management & Research Company, as Associate General Counsel of the Securities and Exchange Commission, and as a visiting professor at Harvard Law School. In an effort to develop and implement policies that we believe will set a new standard in regulatory compliance, MFS has hired two new senior executives. Jeffrey Carp is joining us as General Counsel with responsibility for all of our legal affairs. Previously he was a senior partner with the law firm of Hale and Dorr LLP. Also joining MFS in the new position of Executive Vice President of Regulatory Affairs is Maria Dwyer, who returned to the firm after serving as a senior executive at Fidelity. At MFS, Maria is in charge of compliance, internal audit, and fund treasury. In the area of governance, we have taken steps to enhance the independence of our funds' boards of trustees to better protect the interests of shareholders. We have independent board chairs and at least 75% of the trustees are independent. The trustees will appoint not only their own counsel but also an independent compliance officer. This officer will assist the boards and their committees in monitoring the MFS funds' compliance with federal and state regulations. In February, MFS reached agreements with federal and state regulators to settle their administrative proceedings against the firm and two senior executives in connection with market timing and related issues. Under the terms of the settlements, we agreed to pay $225 million to compensate affected retail fund shareholders. The $225 million will be distributed in accordance with a distribution plan developed by an independent consultant. We have further agreed with state regulators to reduce management fees on certain funds we advise by approximately $25 million annually over the next five years and to pay an administrative fine of $1 million, which will be used for the purpose of investor education. We have introduced a set of policies designed to protect the MFS funds and MFS fund shareholders from market timing abuses. By July, all MFS retail funds, except money market funds, will have a 2% redemption fee on short-term trades. Our global, international, high-yield, mid- and small-cap funds will impose the 2% fee on redemptions or exchanges of fund shares made within 30 calendar days of a share purchase. For all other MFS funds, except money market funds, the 2% fee will be imposed on redemptions or exchanges made within 5 business days of a share purchase. See the fund prospectus for more information. We continue to use fair value pricing, a strategy that minimizes the potential for investors to take advantage of "stale" prices. These can occur, as one example, when funds own foreign securities whose prices close on overseas exchanges in different time zones. At the same time, we enhanced our monitoring of excessive trading. We did so by increasing our staff and updating our computer systems to improve our ability to detect excessive trading in our funds. Finally, we are supporting industry efforts to establish a "hard" 4 p.m. close on all trading, which would prevent the possibility of late trading. In March, MFS reached a second settlement with the SEC under an administrative proceeding resolving the SEC's investigation into how we disclosed brokerage allocation practices in connection with fund sales. According to the settlement order, we did not effectively disclose the potential conflict of interest that may arise from these arrangements. Under the terms of the settlement, MFS has agreed to pay one dollar in disgorgement and $50 million in penalty to MFS fund shareholders. The settlement noted that MFS had policies in place designed to obtain best execution of all trades of securities within MFS portfolios. This past November, MFS eliminated the above mentioned practice of directing brokerage commissions to certain firms in recognition of fund sales. Additionally, we announced in March that we would ban the use of soft dollars to acquire third-party securities research and market data. Soft dollars are permitted under federal securities laws. In fact, it is a common industry practice to use a portion of the brokerage commissions to pay for certain research and execution products and services that are provided to asset managers. MFS will now pay cash out of its own pocket for third-party research and market data. MFS continues to be financially strong, with more than U.S. $140 billion (as of 12/31/03) in assets under management, which continued to be stable during the first quarter of 2004. We also have the full support of our parent company, Sun Life Financial, an internationally diversified financial services firm that manages more than U.S. $269 billion (as of 12/31/03). We chose to settle these two proceedings with the SEC so we could concentrate on serving our fund shareholders. As Chief Investment Officer, my focus is on ensuring that our portfolio teams work closely together and take full advantage of all the resources available to them to deliver the best possible investment performance. As the inventor of the open-end mutual fund in America in 1924, MFS has a strong tradition and culture of innovation. By strengthening our business and governance practices, we believe we have an unprecedented opportunity to set a new standard in the mutual fund industry. As I look ahead, I do so with confidence. The collaboration among MFS employees, many of whom have worked at the firm for their entire careers, continues as we remain singularly dedicated to our clients. It has been our sincere privilege to serve you, and we thank you for the confidence that you have shown in MFS. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer MFS Investment Management(R) March 15, 2004 Note to Shareholders: On February 6, 2004, Jeffrey L. Shames retired as Chairman of MFS. Robert Pozen was named as non-executive Chairman. Also, on February 6, 2004, Robert J. Manning was appointed Chief Executive Officer, President, and Chief Investment Officer. The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed. - -------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - -------------------------------------------------------------------------------- THE MFS(R) DIFFERENCE For 80 years MFS has been offering investors clear paths to pursuing specific investment objectives. Today, millions of individuals and thousands of institutions all over the world look to MFS to manage their assets with insight and care.

INVESTORS CHOOSE MFS FOR OUR o global asset management expertise across all asset classes o time-tested money management process for pursuing consistent results o full spectrum of investment products backed by MFS Original Research(R) o resources and services that match real-life needs TURNING INFORMATION INTO OPPORTUNITY Sound investments begin with sound information.

The release of increasingly positive economic numbers as the period progressed, particularly with regard to corporate earnings and GDP (gross domestic product) growth, helped drive the equity rally. By late 2003, corporate capital spending, which had been weak for some time, had also begun to accelerate. Another driver of the equity rally, in our view, was the U.S. Federal Reserve Board's decision to leave interest rates at a four-decade low throughout the period. While energy prices rose late in the period, core inflation - excluding volatile food and energy prices - remained low relative to historical averages. DETRACTORS FROM PERFORMANCE Over the six-month period ended February 29, 2004, the fund underperformed its benchmark, the Russell 1000 Growth Index, and the average large-cap growth fund as reported by Lipper Inc. Relative to our benchmark, leisure was the fund's weakest area over the period. Stock selection as well as an overweighting in the sector hurt results as the sector underperformed the broad market. Going into the period, we believed our positions in advertising-sensitive broadcasting stocks would benefit from increased ad spending as the U.S. economy recovered. However, advertising spending, particularly in local markets, stagnated somewhat during the period. Fund positions such as media conglomerate Viacom, radio station operator Clear Channel Communications, and radio and television programming provider Westwood One detracted from relative performance. As of the end of the period, however, all three stocks remained significant positions in the portfolio. We believed they could benefit in 2004 from the confluence of a stronger economy, a U.S. presidential election, and the summer Olympics. - ----------------------------------------------- TOP 5 SECTOR WEIGHTINGS AS OF 2/29/04 TECHNOLOGY 29.9% - ----------------------------------------------- HEALTH CARE 18.7% - ----------------------------------------------- FINANCIAL SERVICES 13.1% - ----------------------------------------------- LEISURE 12.6% - ----------------------------------------------- RETAILING 10.1% - ----------------------------------------------- The portfolio is actively managed, and current weightings may be different. - ----------------------------------------------- Stock selection held back performance in the health care sector. Our biggest relative detractor was pharmaceutical giant Pfizer because we held an underweighted position in the company as its shares gained more than the broad market. In technology, stock selection and, to a lesser extent, an overweighting in the sector hurt results as the sector underperformed the broad market. Our positions in storage solution provider VERITAS Software, electronic commerce firm InterActiveCorp, and semiconductor manufacturing equipment company Novellus Systems fell in price over the period. On a relative basis, our position in digital wireless communications firm QUALCOMM also detracted from performance because we sold our holding during the period and missed much of the stock's strong performance. Individual stocks that meaningfully held back relative results included moderate-priced apparel retailer Kohl's. We believe mediocre merchandising, together with adverse weather in key markets, caused the firm to report weak operating results. We viewed these issues as surmountable and maintained our Kohl's holding over the period. Our holding in FedEx also weighed on performance as the company reported weaker than expected shipping volumes. CONTRIBUTORS TO PERFORMANCE In the utilities and communications sector, stock selection as well as a relative overweighting helped performance, as that sector was by far the strongest-performing area in the Russell 1000 Growth Index for the period. Consolidation possibilities, in our view, led to higher prices among cellular service providers in general and our holding in AT&T Wireless in particular. The company agreed during the period to merge with rival Cingular, and we sold our AT&T position on strength heading into the final deal announcement. Our holding in cellular phone company Sprint PCS also benefited from improving subscriber growth and lower customer turnover. An overweighting in the financial services sector also added to results as that sector outperformed the broad market. Insurance and reinsurance firm Ace Ltd. and insurance company American International Group, the largest contributors to performance in the sector, benefited from a global trend toward rising policy premiums. While overall stock selection in technology detracted from relative results, a number of technology stocks were among the fund's top performers for the period. These included programmable logic designer/manufacturer Xilinx, semiconductor maker Analog Devices, and online marketplace eBay. A relative underweighting in semiconductor giant Intel also helped relative results as the stock, which had soared for much of 2003, retreated in early 2004. Concern about the stock's high valuation had led us to underweight Intel. Not owning pharmaceutical giant Merck also helped relative returns as the firm's stock lost ground over the period. We avoided Merck because we felt its medium-term growth prospects would be limited by patent expirations on key products as well as by a dearth of new drugs in the development pipeline. Our position in Walt Disney Co. was also a significant contributor to fund performance. Respectfully, /s/ Margaret Adams /s/ S. Irfan Ali Margaret Adams S.

INDEX DEFINITION THE RUSSELL 1000 GROWTH INDEX - measures the performance of large-cap U.S. growth stocks. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY A portion of the returns shown is attributable to the receipt of a non-recurring payment in settlement of a class action lawsuit. See Notes to Financial Statements. Class A results, including sales charge, reflect the deduction of the maximum 5.75% sales charge. Class B results, including sales charge, reflect the deduction of the applicable contingent deferred sales charge (CDSC), which declines over six years from 4% to 0%. Class C results, including sales charge, redeemed within one year from the end of the calendar month of purchase reflect the deduction of the 1% CDSC. Class I shares have no sales charges and are available only to certain investors. Performance for share classes offered after class B shares includes the performance of the fund's class B shares for periods prior to their offering. Blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the initial share class, and lower performance for share classes with lower operating expenses than the initial share class. 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. KEY RISK CONSIDERATIONS Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. When concentrating on one issuer, the portfolio is sensitive to changes in the value of these securities. The portfolio focuses on companies in a limited number of sectors making it more susceptible to adverse economic, political, or regulatory developments affecting those sectors than a portfolio that invests more broadly. These risks may increase share price volatility. Please see the prospectus for further information regarding these and other risk considerations. This report is prepared for the general information of shareholders. It is authorized for distribution to prospective investors only when preceded or accompanied by a current prospectus. - ----------------------------------------------------------------------------------------------- PORTFOLIO OF INVESTMENTS (unaudited) - 2/29/04 - ----------------------------------------------------------------------------------------------- The Portfolio of Investments is a complete list of all securities owned by your fund.

See notes to financial statements. - ------------------------------------------------------------------------------ NOTES TO FINANCIAL STATEMENTS (unaudited) - ------------------------------------------------------------------------------ (1) BUSINESS AND ORGANIZATION MFS Managed Sectors Fund (the fund) is a non-diversified series of MFS Series Trust I (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. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 fund 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 - The fund uses independent pricing services approved by the Board of Trustees wherever possible to value its portfolio securities. Portfolio securities are valued at current market prices where current market prices are readily available, or the fund may fair value portfolio securities under the direction of the Board of Trustees when a determination is made that current market prices are not readily available. Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Equity securities for which it is determined that current market prices are not readily available will be fair valued under the direction of the Board of Trustees. The fund may also fair value foreign equity securities in cases where closing market prices are not readily available or are deemed not reflective of readily available market prices. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the fund calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the fund may utilize information from an external vendor or other sources to adjust closing market prices of foreign equity securities to reflect what it believes to be the fair value of the securities as of the fund's valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with institutions that the fund's investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The fund requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. The fund 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 fund under each such repurchase agreement. The fund 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 - 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. SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as lending agent, may loan the securities of the fund to certain qualified institutions (the "Borrowers") approved by the fund. 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 fund with indemnification against Borrower default. The fund bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund and 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 fund and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the fund 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. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex- dividend date. The fund was a participant in a class-action lawsuit against Cendant Corporation. On March 26, 2003 the fund received a cash settlement in the amount of $743,793, recorded as a realized gain on investment transactions. The proceeds from the non-recurring litigation settlement resulted in an increase in net asset value of $0.02 per share based on the shares outstanding on the day the proceeds were received. Excluding the effect of this payment from the fund's ending net asset value per share, total return for the year ended August 31, 2003 would have been lower by 0.34%, 0.35%, 0.35%, and 0.35% for class A, B, C and I, respectively. FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. This amount for the six months ended February 29, 2004 is shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The fund'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 fund 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. Common types of book and tax differences that could occur include differences in accounting for currency transactions and real estate investment trusts. The fund paid no distributions for the years ended August 31, 2003 and August 31, 2002. As of August 31, 2003, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Capital loss carryforward $(308,073,328) --------------------------------------------------------- Post-October capital loss deferral (2,744,828) --------------------------------------------------------- Unrealized appreciation 31,140,549 --------------------------------------------------------- Other temporary differences (104,627) --------------------------------------------------------- Post-October capital loss deferrals represent losses realized during the current fiscal year, but recognized for tax purposes in the next fiscal year. For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration. EXPIRATION DATE August 31, 2009 $(18,916,162) --------------------------------------------------------- August 31, 2010 (209,919,760) --------------------------------------------------------- August 31, 2011 (79,237,406) --------------------------------------------------------- Total $(308,073,328) --------------------------------------------------------- MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple classes of shares, which differ in their respective distribution and service fees. All shareholders bear the common expenses of the fund based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. Class B shares will convert to Class A shares, approximately eight years after purchase. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund has an investment advisory agreement with MFS to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at the following annual rates: First $2.5 billion of average net assets 0.75% Average net assets in excess of 2.5 billion 0.70% Management fees incurred for the six months ended February 29, 2004 were 0.75% of average daily net assets on an annualized basis. The fund pays compensation to the Independent Trustees ("Trustees") in the form of both a retainer and attendance fees, and pays no compensation directly to its Trustees who are officers of the investment adviser, or to officers of the fund, all of whom receive remuneration for their services to the fund from MFS. Certain officers and Trustees of the fund are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The fund has an unfunded, defined benefit plan for retired Trustees and an unfunded retirement benefit deferral plan for current Trustees. Included in Trustees' compensation is a net decrease of $14,052 as a result of the change in the fund's pension liability for current Trustees and a pension expense of $2,387 for retired Trustees for the six months ended February 29, 2004. ADMINISTRATOR - The fund has an administrative services agreement with MFS to provide the fund with certain financial, legal, shareholder communications, compliance, and other administrative services. As a partial reimbursement for the cost of providing these services, the fund pays MFS an administrative fee up to the following annual percentage rates of the fund'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% --------------------------------------------------------- DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, as distributor, received $4,976 for six month ended February 29, 2004, as its portion of the sales charge on sales of Class A shares of the fund. The Trustees have adopted a distribution plan for Class A, Class B, and Class C shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as follows: The fund's distribution plan provides that the fund will pay MFD an annual percentage of its average daily net assets attributable to certain share classes in order that MFD may pay expenses on behalf of the fund related to the distribution and servicing of its shares. These expenses include a service fee paid to each securities dealer that enters into a sales agreement with MFD based on the average daily net assets of accounts attributable to such dealers. These fees are calculated based on each class' average daily net assets. The maximum distribution and service fees for each class of shares are as follows: CLASS A CLASS B CLASS C Distribution Fee 0.10% 0.75% 0.75% - ------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% - ------------------------------------------------------------------------------- Total Distribution Plan 0.35% 1.00% 1.00% - ------------------------------------------------------------------------------- MFD retains the service fee for accounts not attributable to a securities dealer, which for the six months ended February 29, 2004, amounted to: CLASS A CLASS B CLASS C Service Fee Retained by MFD $8,043 $858 $4 - ------------------------------------------------------------------------------- Fees incurred under the distribution plan during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C Effective Annual Percentage Rates 0.35% 1.00% 1.00% - ------------------------------------------------------------------------------- Certain Class A and Class C shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within, for Class A shares, 12 months following the purchase, and, for Class C shares, the first year from the end of the calendar month of purchase. A contingent deferred sales charge is imposed on shareholder redemptions of Class B shares in the event of a shareholder redemption within six years from the end of the calendar month of purchase. MFD receives all contingent deferred sales charges. Contingent deferred sales charges imposed during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C Contingent Deferred Sales Charges Imposed $424 $37,533 $101 - -------------------------------------------------------------------------------- SHAREHOLDER SERVICING AGENT - Included in shareholder servicing costs is a fee paid to MFSC, a wholly owned subsidiary of MFS, for its services as shareholder servicing agent. The fee is calculated as a percentage of the fund's average daily net assets at an annual rate of 0.11%, which amounted to $125,539 for the six months ended February 29, 2004. Also included in shareholder servicing costs are out-of-pocket expenses, paid to MFSC, which amounted to $26,899 for the six months ended February 29, 2004, as well as other expenses paid to unaffiliated vendors. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $99,896,626 and $114,890,760, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the fund, as computed on a federal income tax basis, are as follows: Aggregate cost $235,633,925 - -------------------------------------------------------------------------------- Gross unrealized appreciation $36,418,350 - -------------------------------------------------------------------------------- Gross unrealized depreciation (1,501,644) - -------------------------------------------------------------------------------- Net unrealized appreciation $34,916,706 - -------------------------------------------------------------------------------- (5) SHARES OF BENEFICIAL INTEREST The fund's Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. Transactions in fund shares were as follows: Six months ended Year ended 2/29/04 8/31/03 SHARES AMOUNT SHARES AMOUNT CLASS A SHARES Shares sold 727,765 $5,742,252 1,956,338 $12,960,002 - --------------------------------------------------------------------------------------------------------- Shares reacquired (2,305,961) (18,209,458) (5,584,582) (36,876,148) - --------------------------------------------------------------------------------------------------------- Net decrease (1,578,196) $(12,467,206) (3,628,244) $(23,916,146) - --------------------------------------------------------------------------------------------------------- CLASS B SHARES Shares sold 268,543 $2,103,075 818,965 $5,502,570 - --------------------------------------------------------------------------------------------------------- Shares reacquired (803,028) (6,288,912) (2,166,390) (14,423,562) - --------------------------------------------------------------------------------------------------------- Net decrease (534,485) $(4,185,837) (1,347,425) $(8,920,992) - --------------------------------------------------------------------------------------------------------- CLASS C SHARES Shares sold 30,625 $236,295 160,262 $1,068,677 - --------------------------------------------------------------------------------------------------------- Shares reacquired (25,736) (200,448) (185,934) (1,225,803) - --------------------------------------------------------------------------------------------------------- Net increase (decrease) 4,889 $35,847 (25,672) $(157,126) - --------------------------------------------------------------------------------------------------------- CLASS I SHARES Shares sold 9,588 $75,294 26,922 $183,217 - --------------------------------------------------------------------------------------------------------- Shares reacquired (12,766) (103,244) (39,742) (270,591) - --------------------------------------------------------------------------------------------------------- Net decrease (3,178) $(27,950) (12,820) $(87,374) - --------------------------------------------------------------------------------------------------------- (6) LINE OF CREDIT The fund and other affiliated funds participate in an $800 million 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 plus 0.50%. In addition, a commitment fee, based on the average daily unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the fund for the six months ended February 29, 2004, was $842. The fund had no borrowings during the period. (7) LEGAL PROCEEDINGS On March 31, 2004, MFS settled an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. Under the terms of the settlement, in which MFS neither admitted nor denied any wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50 million in penalty to certain MFS funds, pursuant to a plan to be approved by an independent distribution consultant. The agreement with the SEC is reflected in an order of the SEC. The settlement order states that MFS failed to adequately disclose to the Boards of Trustees and to shareholders of the MFS funds the specifics of its preferred arrangements with certain brokerage firms selling MFS fund shares. The settlement order states that MFS had in place policies designed to obtain best execution of all fund trades. As part of the settlement, MFS also agreed to retain an independent compliance consultant to review the completeness of its disclosure to fund trustees and to fund shareholders of strategic alliances between MFS or its affiliates and broker-dealers and other financial advisers who support the sale of fund shares. The brokerage allocation practices which were the subject of this proceeding were discontinued by MFS in November 2003. In addition, in February, 2004, MFS reached agreement with the Securities and Exchange Commission ("SEC"), the New York Attorney General ("NYAG") and the Bureau of Securities Regulation of the State of New Hampshire ("NH") to settle administrative proceedings alleging false and misleading information in certain MFS fund prospectuses regarding market timing and related matters (the "February Settlements"). These regulators alleged that prospectus language for certain MFS funds was false and misleading because, although the prospectuses for those funds in the regulators' view indicated that the funds prohibited market timing, MFS did not limit trading activity in 11 domestic large cap stock, high grade bond and money market funds. MFS' former Chief Executive Officer, John W. Ballen, and former President, Kevin R. Parke, have also reached agreement with the SEC (Messrs. Ballen and Parke resigned their director and officer positions with MFS on February 13, 2004). Under the terms of the February Settlements, MFS and the executives neither admit nor deny wrongdoing. Under the terms of the February Settlements, a $225 million pool has been established for distribution to shareholders in certain of the MFS funds offered to retail investors ("Retail Funds"), which has been funded by MFS and of which $50 million is characterized as a penalty. This pool will be distributed in accordance with a methodology developed by an independent distribution consultant in consultation with MFS and the Boards of Trustees of the Retail Funds, and acceptable to the SEC. MFS has further agreed with the NYAG to reduce its management fees in the aggregate amount of approximately $25 million annually over the next five years, and not to increase certain management fees during this period. MFS has also paid an administrative fine to NH in the amount of $1 million, which will be used for investor education purposes (NH will retain $250,000 and $750,000 will be contributed to the North American Securities Administrators Association's Investor Protection Trust). In addition, MFS and the Retail Funds will adopt certain governance changes. Messrs. Ballen and Parke have agreed to temporary suspensions from association with any registered investment company or investment adviser, will pay approximately $315,000 each to the SEC, and resigned their positions as trustees of all MFS funds, and Mr. Ballen resigned his position as President of all MFS funds, effective February 6, 2004. Messrs. Ballen and Parke will not be returning to MFS or the MFS funds after their suspensions. Since December 2003, MFS, Sun Life Financial Inc., various MFS funds, the Trustees of these MFS funds, and certain officers of MFS have been named as defendants in multiple lawsuits filed in federal and state courts. The lawsuits variously have been commenced as class actions or individual actions on behalf of investors who purchased, held or redeemed shares of the funds during specified periods, as class actions on behalf of participants in certain retirement plan accounts, or as derivative actions on behalf of the MFS funds. The lawsuits generally allege that some or all of the defendants (i) permitted or acquiesced in market timing and/or late trading in some of the MFS funds, inadequately disclosed MFS' internal policies concerning market timing and such matters, and received excessive compensation as fiduciaries to the MFS fund, or (ii) permitted or acquiesced in the improper use of fund assets by MFS to support the distribution of fund shares and inadequately disclosed MFS' use of fund assets in this manner. The actions assert that some or all of the defendants violated the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of 1940 and the Investment Advisers Act of 1940, the Employee Retirement Income Security Act of 1974, as well as fiduciary duties and other violations of common law. The lawsuits seek unspecified compensatory damages. Insofar as any of the actions is appropriately brought derivatively on behalf of any of the MFS funds, any recovery will inure to the benefit of the funds. The defendants are reviewing the allegations of the multiple complaints and will respond appropriately. Additional lawsuits based on similar allegations may be filed in the future. Any potential resolution of these matters may include, but not be limited to, judgments or settlements for damages against MFS, the MFS funds, or any other named defendant. As noted above, as part of the regulatory settlements, MFS has established a restitution pool in the amount of $225 million to compensate certain shareholders of the Retail Funds for damages that they allegedly sustained as a result of market timing or late trading in certain of the funds, and will pay $50 million to compensate certain MFS funds based upon the amount of brokerage commissions allocated in recognition of fund sales. It is not clear whether these amounts will be sufficient to compensate shareholders for all of the damage they allegedly sustained, whether certain shareholders or putative class members may have additional claims to compensation, or whether the damages that may be awarded in any of the actions will exceed these amounts. In the event the MFS funds incur any losses, costs or expenses in connection with such lawsuits, the Boards of Trustees of the affected funds may pursue claims on behalf of such funds against any party that may have liability to the funds in respect thereof. Review of these matters by the independent Trustees of the MFS funds and their counsel is continuing. There can be no assurance that these regulatory actions and lawsuits, or the adverse publicity associated with these developments will not result in increased fund redemptions, reduced sales of fund shares, or other adverse consequences to the funds. - -------------------------------------------------------------------------------------------------------------- TRUSTEES AND OFFICERS - -------------------------------------------------------------------------------------------------------------- The following tables present certain information regarding the Trustees and officers of MFS Series Trust I, of which the fund is a series, including their principal occupations, which, unless specific dates are shown, are of more than five years' duration, although the titles may not have been the same throughout.

Manning] As the firm's new Chief Executive Officer, I want to thank you for your continued trust in MFS and tell you about the series of actions we have taken since our recent settlements with the regulators. These actions are designed to enhance the governance structure of the MFS funds, tighten our business practices, and strengthen the management team at MFS. In early February, Robert Pozen joined MFS as non-executive Chairman. A seasoned veteran of the mutual fund industry, Bob has held prior positions as President of Fidelity Management & Research Company, as Associate General Counsel of the Securities and Exchange Commission, and as a visiting professor at Harvard Law School. In an effort to develop and implement policies that we believe will set a new standard in regulatory compliance, MFS has hired two new senior executives. Jeffrey Carp is joining us as General Counsel with responsibility for all of our legal affairs. Previously he was a senior partner with the law firm of Hale and Dorr LLP. Also joining MFS in the new position of Executive Vice President of Regulatory Affairs is Maria Dwyer, who returned to the firm after serving as a senior executive at Fidelity. At MFS, Maria is in charge of compliance, internal audit, and fund treasury. In the area of governance, we have taken steps to enhance the independence of our funds' boards of trustees to better protect the interests of shareholders. We have independent board chairs and at least 75% of the trustees are independent. The trustees will appoint not only their own counsel but also an independent compliance officer. This officer will assist the boards and their committees in monitoring the MFS funds' compliance with federal and state regulations. In February, MFS reached agreements with federal and state regulators to settle their administrative proceedings against the firm and two senior executives in connection with market timing and related issues. Under the terms of the settlements, we agreed to pay $225 million to compensate affected retail fund shareholders. The $225 million will be distributed in accordance with a distribution plan developed by an independent consultant. We have further agreed with state regulators to reduce management fees on certain funds we advise by approximately $25 million annually over the next five years and to pay an administrative fine of $1 million, which will be used for the purpose of investor education. We have introduced a set of policies designed to protect the MFS funds and MFS fund shareholders from market timing abuses. By July, all MFS retail funds, except money market funds, will have a 2% redemption fee on short-term trades. Our global, international, high-yield, mid- and small-cap funds will impose the 2% fee on redemptions or exchanges of fund shares made within 30 calendar days of a share purchase. For all other MFS funds, except money market funds, the 2% fee will be imposed on redemptions or exchanges made within 5 business days of a share purchase. See the fund prospectus for more information. We continue to use fair value pricing, a strategy that minimizes the potential for investors to take advantage of "stale" prices. These can occur, as one example, when funds own foreign securities whose prices close on overseas exchanges in different time zones. At the same time, we enhanced our monitoring of excessive trading. We did so by increasing our staff and updating our computer systems to improve our ability to detect excessive trading in our funds. Finally, we are supporting industry efforts to establish a "hard" 4 p.m. close on all trading, which would prevent the possibility of late trading. In March, MFS reached a second settlement with the SEC under an administrative proceeding resolving the SEC's investigation into how we disclosed brokerage allocation practices in connection with fund sales. According to the settlement order, we did not effectively disclose the potential conflict of interest that may arise from these arrangements. Under the terms of the settlement, MFS has agreed to pay one dollar in disgorgement and $50 million in penalty to MFS fund shareholders. The settlement noted that MFS had policies in place designed to obtain best execution of all trades of securities within MFS portfolios. This past November, MFS eliminated the above mentioned practice of directing brokerage commissions to certain firms in recognition of fund sales. Additionally, we announced in March that we would ban the use of soft dollars to acquire third-party securities research and market data. Soft dollars are permitted under federal securities laws. In fact, it is a common industry practice to use a portion of the brokerage commissions to pay for certain research and execution products and services that are provided to asset managers. MFS will now pay cash out of its own pocket for third-party research and market data. MFS continues to be financially strong, with more than U.S. $140 billion (as of 12/31/03) in assets under management, which continued to be stable during the first quarter of 2004. We also have the full support of our parent company, Sun Life Financial, an internationally diversified financial services firm that manages more than U.S. $269 billion (as of 12/31/03). We chose to settle these two proceedings with the SEC so we could concentrate on serving our fund shareholders. As Chief Investment Officer, my focus is on ensuring that our portfolio teams work closely together and take full advantage of all the resources available to them to deliver the best possible investment performance. As the inventor of the open-end mutual fund in America in 1924, MFS has a strong tradition and culture of innovation. By strengthening our business and governance practices, we believe we have an unprecedented opportunity to set a new standard in the mutual fund industry. As I look ahead, I do so with confidence. The collaboration among MFS employees, many of whom have worked at the firm for their entire careers, continues as we remain singularly dedicated to our clients. It has been our sincere privilege to serve you, and we thank you for the confidence that you have shown in MFS. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer MFS Investment Management(R) March 15, 2004 Note to Shareholders: On February 6, 2004, Jeffrey L. Shames retired as Chairman of MFS. Robert Pozen was named as non-executive Chairman. Also, on February 6, 2004, Robert J. Manning was appointed Chief Executive Officer, President, and Chief Investment Officer.

Today, millions of individuals and thousands of institutions all over the world look to MFS to manage their assets with insight and care.

When you invest with MFS, you invest with a company dedicated to helping you realize your long-term financial goals. INVESTORS CHOOSE MFS FOR OUR o global asset management expertise across all asset classes o time-tested money management process for pursuing consistent results o full spectrum of investment products backed by MFS Original Research(R) o resources and services that match real-life needs TURNING INFORMATION INTO OPPORTUNITY Sound investments begin with sound information. MFS has been doing its own research and analyzing findings in-house for decades. The process we use to uncover opportunity is called MFS Original Research(R). MFS ORIGINAL RESEARCH INVOLVES: o meeting with the management of 3,000 companies each year to assess their business plans and the managers' ability to execute those plans o making onsite visits to more than 2,000 companies annually to gain first-hand knowledge of their operations and products o analyzing financial statements and balance sheets o talking extensively with companies' customers and competitors o developing our own proprietary estimates of companies' earnings - ------------------------------------------------------------------------------- MANAGEMENT REVIEW - ------------------------------------------------------------------------------- MARKET ENVIRONMENT The turnaround in global stock markets that began in the spring of 2003 continued for most of the six-month period ended February 29, 2004. The release of increasingly positive economic numbers as the period progressed, particularly with regard to corporate earnings and GDP (gross domestic product) growth, helped drive the equity rally. By late 2003, corporate capital spending, which had been weak for some time, had also begun to accelerate. Another driver of the equity rally, in our view, was the U.S. Federal Reserve Board's decision to leave interest rates at a four-decade low throughout the period. While energy prices rose late in the period, core inflation -- excluding volatile food and energy prices -- remained very low relative to historical averages. In contrast to the broader market which continued to advance through February 2004, however, technology stocks retreated somewhat in the last month of the quarter. FUND POSITIONING In August 2003, MFS Global Telecommunications Fund was reorganized and its assets were merged with those of MFS Technology Fund. There were significant synergies between the two funds; however, the addition of utilities and telephone services companies reduced the combined funds' exposure to the more pure technology industries. DETRACTORS FROM PERFORMANCE The fund's performance was hampered by stock selection and an underweighting in the network and telecommunications industry, particularly in wireless and wireline infrastructure companies. As the period began, we believed that wireless and wireline companies would continue to hold back capital spending on infrastructure as they had for the past few years. Instead, these companies ramped up their spending, and infrastructure companies such as Nortel Networks, Lucent Technologies, and QUALCOMM performed very well. Although the fund owned stock in Nortel and QUALCOMM, we remained underweighted in these stocks relative to the benchmark and missed some of the strong returns generated by the two firms. As a result, these stocks held back relative returns. Not owning Lucent stock similarly detracted from fund results. - ----------------------------------------------- TOP 5 INDUSTRY WEIGHTINGS AS OF 2/29/04 ELECTRONICS 31.0% - ----------------------------------------------- NETWORK AND TELECOM EQUIPMENT 16.8% - ----------------------------------------------- COMPUTER SOFTWARE 16.7% - ----------------------------------------------- BUSINESS SERVICES 9.6% - ----------------------------------------------- PC AND PERIPHERALS 9.0% - ----------------------------------------------- The portfolio is actively managed, and current weightings may be different. - ----------------------------------------------- In addition, stock selection among Internet stocks held back fund returns. Some of the stocks we owned underperformed the fund's benchmark, the Goldman Sachs Technology Index, and some of the group's stocks that we did not own outperformed the index. The fund's positions in BISYS and White Electronic Designs also detracted from performance. Information processing firm BISYS failed to meet its revenue projections for its fee business and insurance divisions. The fund sold its BISYS stock because of poor performance. White Electronic Designs manufactures semiconductors used in military applications. When an accounting change negatively affected how the company recognized revenue, the company's stock price declined. The fund's cash position also detracted from relative performance. As with nearly all mutual funds, this fund holds some cash to buy new holdings and to cover shareholder redemptions. In a period when equity markets rose sharply, cash hurt performance against our benchmark which has no cash position. CONTRIBUTORS TO PERFORMANCE The addition of MFS Global Telecommunications Fund assets resulted in an overweighting of wireless communications stocks in the combined fund which contributed significantly to relative returns for the period. Stock selection in the industry also added to performance, especially when our wireless positions held their values better than other technology firms during the downturn in February of 2004. Fund returns were helped by an overweighted position in Andrew Corp., a wireless communications equipment company that we believed was positioned to benefit from infrastructure spending. Stock selection in the computer software industry was also strong. Examples include the fund's holdings in Netscreen Technologies, which specializes in network security solutions, and Akamai Technologies, which specializes in "e-business" infrastructure. Both companies added to relative performance. The fund sold its Netscreen position when the stock reached our price target. The fund also benefited from relative underweightings in Microsoft, Intel, and Dell during a period in which we observed that larger capitalization companies tended to underperform the market as compared to smaller capitalization companies. Our holdings in Flextronics International, which provides contract manufacturing services for computer and electronics companies, also contributed to the fund's relative return.

INDEX DEFINITIONS GOLDMAN SACHS TECHNOLOGY INDEX - The Goldman Sachs Technology Index is a commonly used measure of technology stock performance.

NOTES TO PERFORMANCE SUMMARY Class A results, including sales charge, reflects the deduction of the maximum 5.75% sales charge. Class B results, including sales charge, reflects the deduction of the applicable contingent deferred sales charge (CDSC), which declines over six years from 4% to 0%. Class C results, including sales charge, redeemed within one year from the end of the calendar month of purchase reflects the deduction of the 1% CDSC. Class I shares have no sales charges and are available only to certain investors. Class R1 and Class R2 shares have no sales charges and are available only to certain retirement plans. Performance for share classes offered after Class A shares includes the performance of the fund's Class A shares for periods prior to their offering. Blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the initial share class, and lower performance for share classes with lower operating expenses than the initial share class. Performance results reflect any applicable subsidies and waivers in effect during the periods shown. Without such subsidies and waivers, the fund's performance would be less favorable. See the prospectus and financial statements for details. KEY RISK CONSIDERATIONS Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. When concentrating on one issuer, the portfolio is sensitive to changes in the value of these securities. The portfolio focuses on companies in a limited number of sectors making it more susceptible to adverse economic, political, or regulatory developments affecting those sectors than a portfolio that invests more broadly. Investing in small and/or emerging growth companies is riskier than investing in more established companies. These risks may increase share price volatility. Please see the prospectus for further information regarding these and other risk considerations. This report is prepared for the general information of shareholders. It is authorized for distribution to prospective investors only when preceded or accompanied by a current prospectus. - ---------------------------------------------------------------------------------------------- PORTFOLIO OF INVESTMENTS (unaudited) - 2/29/04 - ---------------------------------------------------------------------------------------------- The Portfolio of Investments is a complete list of all securities owned by your fund.

This arrangement is effected by MFS bearing all of the fund's Other Expenses during the fund's fiscal year and the fund paying MFS an expense reimbursement fee not greater than 0.40% of average daily net assets for Class A. To the extent that the expense reimbursement fee exceeds the fund's actual expenses, the excess will be applied to unreimbursed amounts paid by MFS under the current agreement. This agreement will terminate on the earlier of December 31, 2004, or such date as all expenses previously borne by MFS under the agreement have been paid by the fund. The fund will not be required to reimburse MFS for expenses borne under a previous agreement that expired on December 31, 2003. Prior to April 14, 2000, the investment adviser and the distributor waived their fees.

See notes to financial statements. - ------------------------------------------------------------------------------ NOTES TO FINANCIAL STATEMENTS (unaudited) - ------------------------------------------------------------------------------ (1) BUSINESS AND ORGANIZATION MFS Technology Fund (the fund) is a diversified series of MFS Series Trust I (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. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 fund 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 - The fund uses independent pricing services approved by the Board of Trustees wherever possible to value its portfolio securities. Portfolio securities are valued at current market prices where current market prices are readily available, or the fund may fair value portfolio securities under the direction of the Board of Trustees when a determination is made that current market prices are not readily available. Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Equity securities for which it is determined that current market prices are not readily available will be fair valued under the direction of the Board of Trustees. The fund may also fair value foreign equity securities in cases where closing market prices are not readily available or are deemed not reflective of readily available market prices. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the fund calculates its net asset value (generally, the close of the New York Stock Exchange) that may impact the value of securities traded in these foreign markets. In these cases, the fund may utilize information from an external vendor or other sources to adjust closing market prices of foreign equity securities to reflect what it believes to be the fair value of the securities as of the fund's valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. 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. FOREIGN CURRENCY TRANSLATION - 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. SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as lending agent, may loan the securities of the fund to certain qualified institutions (the "Borrowers") approved by the fund. 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 fund with indemnification against Borrower default. The fund bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund and 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 fund and the lending agent. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the fund and the lending agent. Income from securities lending is disclosed 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. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with accounting principles generally accepted in the United States of America. All discount is accreted for 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. FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. During the six months ended February 29, 2004, the fund's custodian fees were reduced by $301 under this arrangement. The fund has entered into a commission recapture agreement under which certain brokers will credit the fund a portion of the commissions generated to offset certain expenses of the fund. For the six months ended February 29, 2004, the fund's miscellaneous expenses were reduced by $7,203 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The fund'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 fund 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. Common types of book and tax differences that could occur include differences in accounting for currency transactions. The fund paid no distributions for the years ended August 31, 2003, and August 31, 2002. As of August 31, 2003, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Capital loss carryforward $(361,065,435) - -------------------------------------------------------------------------------- Post-October capital loss deferral (17,293,212) - -------------------------------------------------------------------------------- Unrealized appreciation 26,018,772 - -------------------------------------------------------------------------------- Post-October capital loss deferrals represent losses realized during the current fiscal year, but recognized for tax purposes in the next fiscal year. For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration. EXPIRATION DATE August 31, 2007 $(1,836,344) --------------------------------------------------------- August 31, 2008 (7,671,099) --------------------------------------------------------- August 31, 2009 (114,220,557) --------------------------------------------------------- August 31, 2010 (162,445,817) --------------------------------------------------------- August 31, 2011 (74,891,618) --------------------------------------------------------- Total $(361,065,435) --------------------------------------------------------- The availability of a portion of these respective capital loss carryforwards, which were acquired on August 22, 2003, in connection with the MFS Global Telecommunications Fund acquisition, may be limited in a given year. MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple classes of shares, which differ in their respective distribution and service fees. All shareholders bear the common expenses of the fund based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. Class B shares will convert to Class A shares approximately eight years after purchase. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund has an investment advisory agreement with 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 0.75% of the fund's average daily net assets. MFS has contractually agreed, subject to reimbursement, to bear a portion of the fund's "Other Expenses", which are defined as the fund's operating expenses, exclusive of management, distribution and service, and certain other fees and expenses, such that Other Expenses do not exceed 0.40% annually. This arrangement is effected by MFS bearing all of the fund's Other Expenses during the fund's fiscal year and the fund paying MFS an expense reimbursement fee not greater than 0.40% of average daily net assets for Class A, Class B, Class C, Class I, and Class R1 and not greater than 0.65% of average daily net assets for Class R2. To the extent that the expense reimbursement fee exceeds the fund's actual expenses, the excess will be applied to unreimbursed amounts paid by MFS under the current agreement. This agreement will terminate on the earlier of December 31, 2004, or such date as all expenses previously borne by MFS under the agreement have been paid by the fund. At February 29, 2004, aggregate unreimbursed expenses amounted to $99,127. The fund will not be required to reimburse MFS the $307,920 for expenses borne under a previous agreement that expired December 31, 2003. The fund pays compensation to the Independent Trustees ("Trustees") in the form of both a retainer and attendance fees, and pays no compensation directly to its Trustees who are officers of the investment adviser, or to officers of the fund, all of whom receive remuneration for their services to the fund from MFS. Certain officers and Trustees of the fund are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The fund has an unfunded, defined benefit plan for retired Trustees and an unfunded retirement benefit deferral plan for current Trustees. Included in Trustees' compensation is a net decrease of $11,176 as a result of the change in the fund's pension liability for current Trustees and a pension expense of $308 for retired Trustees for the six months ended February 29, 2004. ADMINISTRATOR - The fund has an administrative services agreement with MFS to provide the fund with certain financial, legal, shareholder communications, compliance, and other administrative services. As a partial reimbursement for the cost of providing these services, the fund pays MFS an administrative fee up to the following annual percentage rates of the fund'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% --------------------------------------------------------- In addition to the administrative services provided by MFS to the fund as described above, MFS is responsible for providing certain administrative services with respect to Class R2 shares. These services include various administrative, recordkeeping, and communication/educational services with respect to the retirement plans which invest in Class R2 shares, and may be provided directly by MFS or by a third party. The fund pays an annual 0.25% administrative service fee solely from the assets of Class R2 shares to MFS for the provision of these services. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, as distributor, received $11,380 for the six months ended February 29, 2004, as its portion of the sales charge on sales of Class A shares of the fund. The Trustees have adopted a distribution plan for Class A, Class B, Class C, Class R1 and Class R2, shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as follows: The fund's distribution plan provides that the fund will pay MFD an annual percentage of its average daily net assets attributable to certain share classes in order that MFD may pay expenses on behalf of the fund related to the distribution and servicing of its shares. These expenses include a service fee paid to each securities dealer that enters into a sales agreement with MFD based on the average daily net assets of accounts attributable to such dealers. These fees are calculated based on each class' average daily net assets. The maximum distribution and service fees for each class of shares are as follows: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Distribution Fee 0.10% 0.75% 0.75% 0.25% 0.25% - ------------------------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% 0.25% 0.25% - ------------------------------------------------------------------------------------------------------------------- Total Distribution Plan 0.35% 1.00% 1.00% 0.50% 0.50% - ------------------------------------------------------------------------------------------------------------------- MFD retains the service fee for accounts not attributable to a securities dealer, which for the six months ended February 29, 2004, amounted to: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Service Fee Retained by MFD $15,001 $498 $133 $-- $-- - ------------------------------------------------------------------------------------------------------------------- Fees incurred under the distribution plan during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Effective Annual Percentage Rates 0.35% 1.00% 1.00% 0.50% 0.50% - ------------------------------------------------------------------------------------------------------------------- Certain Class A and Class C shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within, for Class A shares, 12 months following the purchase, and, for Class C shares, the first year from the end of the calendar month of purchase. A contingent deferred sales charge is imposed on shareholder redemptions of Class B shares in the event of a shareholder redemption within six years from the end of the calendar month of purchase. MFD receives all contingent deferred sales charges. Contingent deferred sales charges imposed during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Contingent Deferred Sales Charges Imposed $842 $105,664 $1,039 $-- $-- - ------------------------------------------------------------------------------------------------------------------- SHAREHOLDER SERVICING AGENT - Included in shareholder servicing costs is a fee paid to MFSC, a wholly owned subsidiary of MFS, for its services as shareholder servicing agent. The fee is calculated as a percentage of the fund's average daily net assets at an annual rate of 0.11%, which amounted to $114,944 for the six months ended February 29, 2004. Also included in shareholder servicing costs are out-of-pocket expenses, paid to MFSC, which amounted to $95,269 for the six months ended February 29, 2004, as well as other expenses paid to unaffiliated vendors. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $175,982,439 and $164,032,675, respectively. The cost and unrealized appreciation and depreciation in the value of the investments owned by the fund, as computed on a federal income tax basis, are as follows: Aggregate cost $220,342,037 --------------------------------------------------------- Gross unrealized appreciation $34,001,014 Gross unrealized depreciation (4,406,925) --------------------------------------------------------- Net unrealized appreciation $29,594,089 --------------------------------------------------------- (5) SHARES OF BENEFICIAL INTEREST The fund's Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest.

(6) LINE OF CREDIT The fund and other affiliated funds participate in an $800 million 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 plus 0.50%. In addition, a commitment fee, based on the average daily unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the fund for the six months ended February 29, 2004, was $790. The fund had no borrowings during the period. (7) ACQUISITIONS At close of business on August 22, 2003, the fund acquired all of the assets and liabilities of the MFS Global Telecommunications Fund. The acquisition was accomplished by a tax-free exchange of 1,839,638, 2,762,550, and 968,256 shares of Class A, Class B and Class C shares of the fund valued at $14,901,068, $21,934,645, and $7,678,267, respectively, for all of the assets and liabilities of MFS Global Telecommunications Fund. The MFS Global Telecommunications Fund then converted all of its outstanding shares of the fund and distributed those shares to its shareholders. The MFS Global Telecommunications Fund's net assets on that date were $44,513,980, including $2,654,484 of unrealized appreciation, $0 of accumulated net investment income and $(201,803,373) of accumulated net realized loss on investments and foreign currency transactions. These assets were combined with those of the fund. The aggregate net assets of the fund after the acquisition were $181,944,611. (8) LEGAL PROCEEDINGS On March 31, 2004, MFS settled an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. Under the terms of the settlement, in which MFS neither admitted nor denied any wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50 million in penalty to certain MFS funds, pursuant to a plan to be approved by an independent distribution consultant. The agreement with the SEC is reflected in an order of the SEC. The settlement order states that MFS failed to adequately disclose to the Boards of Trustees and to shareholders of the MFS funds the specifics of its preferred arrangements with certain brokerage firms selling MFS fund shares. The settlement order states that MFS had in place policies designed to obtain best execution of all fund trades. As part of the settlement, MFS also agreed to retain an independent compliance consultant to review the completeness of its disclosure to fund trustees and to fund shareholders of strategic alliances between MFS or its affiliates and broker-dealers and other financial advisers who support the sale of fund shares. The brokerage allocation practices which were the subject of this proceeding were discontinued by MFS in November 2003. In addition, in February, 2004, MFS reached agreement with the Securities and Exchange Commission ("SEC"), the New York Attorney General ("NYAG") and the Bureau of Securities Regulation of the State of New Hampshire ("NH") to settle administrative proceedings alleging false and misleading information in certain MFS fund prospectuses regarding market timing and related matters (the "February Settlements"). These regulators alleged that prospectus language for certain MFS funds was false and misleading because, although the prospectuses for those funds in the regulators' view indicated that the funds prohibited market timing, MFS did not limit trading activity in 11 domestic large cap stock, high grade bond and money market funds. MFS' former Chief Executive Officer, John W. Ballen, and former President, Kevin R. Parke, have also reached agreement with the SEC (Messrs. Ballen and Parke resigned their director and officer positions with MFS on February 13, 2004). Under the terms of the February Settlements, MFS and the executives neither admit nor deny wrongdoing. Under the terms of the February Settlements, a $225 million pool has been established for distribution to shareholders in certain of the MFS funds offered to retail investors ("Retail Funds"), which has been funded by MFS and of which $50 million is characterized as a penalty. This pool will be distributed in accordance with a methodology developed by an independent distribution consultant in consultation with MFS and the Boards of Trustees of the Retail Funds, and acceptable to the SEC. MFS has further agreed with the NYAG to reduce its management fees in the aggregate amount of approximately $25 million annually over the next five years, and not to increase certain management fees during this period. MFS has also paid an administrative fine to NH in the amount of $1 million, which will be used for investor education purposes (NH will retain $250,000 and $750,000 will be contributed to the North American Securities Administrators Association's Investor Protection Trust). In addition, MFS and the Retail Funds will adopt certain governance changes. Messrs. Ballen and Parke have agreed to temporary suspensions from association with any registered investment company or investment adviser, will pay approximately $315,000 each to the SEC, and resigned their positions as trustees of all MFS funds, and Mr. Ballen resigned his position as President of all MFS funds, effective February 6, 2004. Messrs. Ballen and Parke will not be returning to MFS or the MFS funds after their suspensions. Since December 2003, MFS, Sun Life Financial Inc., various MFS funds, the Trustees of these MFS funds, and certain officers of MFS have been named as defendants in multiple lawsuits filed in federal and state courts. The lawsuits variously have been commenced as class actions or individual actions on behalf of investors who purchased, held or redeemed shares of the funds during specified periods, as class actions on behalf of participants in certain retirement plan accounts, or as derivative actions on behalf of the MFS funds. The lawsuits generally allege that some or all of the defendants (i) permitted or acquiesced in market timing and/or late trading in some of the MFS funds, inadequately disclosed MFS' internal policies concerning market timing and such matters, and received excessive compensation as fiduciaries to the MFS fund, or (ii) permitted or acquiesced in the improper use of fund assets by MFS to support the distribution of fund shares and inadequately disclosed MFS' use of fund assets in this manner. The actions assert that some or all of the defendants violated the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of 1940 and the Investment Advisers Act of 1940, the Employee Retirement Income Security Act of 1974, as well as fiduciary duties and other violations of common law. The lawsuits seek unspecified compensatory damages. Insofar as any of the actions is appropriately brought derivatively on behalf of any of the MFS funds, any recovery will inure to the benefit of the funds. The defendants are reviewing the allegations of the multiple complaints and will respond appropriately. Additional lawsuits based on similar allegations may be filed in the future. Any potential resolution of these matters may include, but not be limited to, judgments or settlements for damages against MFS, the MFS funds, or any other named defendant. As noted above, as part of the regulatory settlements, MFS has established a restitution pool in the amount of $225 million to compensate certain shareholders of the Retail Funds for damages that they allegedly sustained as a result of market timing or late trading in certain of the funds, and will pay $50 million to compensate certain MFS funds based upon the amount of brokerage commissions allocated in recognition of fund sales. It is not clear whether these amounts will be sufficient to compensate shareholders for all of the damage they allegedly sustained, whether certain shareholders or putative class members may have additional claims to compensation, or whether the damages that may be awarded in any of the actions will exceed these amounts. In the event the MFS funds incur any losses, costs or expenses in connection with such lawsuits, the Boards of Trustees of the affected funds may pursue claims on behalf of such funds against any party that may have liability to the funds in respect thereof. Review of these matters by the independent Trustees of the MFS funds and their counsel is continuing. There can be no assurance that these regulatory actions and lawsuits, or the adverse publicity associated with these developments will not result in increased fund redemptions, reduced sales of fund shares, or other adverse consequences to the funds. - -------------------------------------------------------------------------------------------------------------- TRUSTEES AND OFFICERS - -------------------------------------------------------------------------------------------------------------- The following tables present certain information regarding the Trustees and officers of MFS Series Trust I, of which the fund is a series, including their principal occupations, which, unless specific dates are shown, are of more than five years' duration, although the titles may not have been the same throughout.
