The fund may invest in securities of companies of any size. The fund is nondiversified, which means that it may invest a relatively high percentage of its assets in a small number of holdings. In selecting securities for the portfolio, we use a bottom-up approach to look for companies that possess strong management teams with clearly defined strategies, strong franchises with substantial barriers to new entrants, strong cash flows, recurring revenue streams, potential for high profit margins, and a catalyst that may accelerate growth. CONTRIBUTORS TO PERFORMANCE Over the twelve-month period ending August 31, 2003, the fund's strongest- performing sectors included autos & housing, technology, and retailing. Within the autos & housing sector, stocks that helped performance included the fund's two top-performing holdings, Stanley Electric and Nissan Motor. In the technology sector, positions that contributed to results included Brother Industries, Canon, and Citizen Electronics. By the end of the period, we had sold our Nissan Motor and Canon holdings and taken some profits. The largest contributor in the retailing sector was our position in Fast Retailing; relative performance in the sector was also aided by our avoidance of Seven- Eleven Japan and Ito-Yokado, which plunged in value during the period. DETRACTORS FROM PERFORMANCE Leisure and energy were the fund's weakest-performing areas over the reporting period. Sega was the portfolio's chief detractor in the leisure sector, and we sold the position during the period. The fund's position in Nippon Oil was the key factor in its underperformance in the energy sector. Other holdings that held back relative performance included Credit Saison and Sompo Japan Insurance in the financial services sector, Shiseido in the consumer staples sector, and NTT DoCoMo in the utilities and communications sector. By period- end, Sompo Japan, Shiseido, and NTT DoCoMo had been sold out of the portfolio. Respectfully, /s/ David A. Antonelli David A. Antonelli Director of Global Equity Research The opinions expressed in this report are those of the Director of Global Equity Research and are current only through the end of the period of the report as stated on the cover. These views are subject to change at any time based on market and other conditions, and no forecasts can be guaranteed. The portfolio is actively managed, and current holdings may be different. - ------------------------------------------------------------------------------- PERFORMANCE SUMMARY THROUGH 8/31/03 - ------------------------------------------------------------------------------- Currently, the fund offers only Class A and/or Class I shares, which are available for purchase at net asset value only by residents of the Commonwealth of Massachusetts who are employees (or certain relatives of employees) of MFS and its affiliates or members of the governing boards of the various funds sponsored by MFS. The following information illustrates the historical performance of the fund's Class A shares in comparison to their benchmarks. Performance results reflect the maximum applicable sales charge and the percentage change in net asset value, including the reinvestment of any dividends and capital gains distributions. Benchmark comparisons are unmanaged and do not reflect any fees or expenses. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. GROWTH OF A HYPOTHETICAL $10,000 INVESTMENT For the period from the commencement of the fund's investment operations, June 1, 2000, through August 31, 2003. Index information is from June 1, 2000.

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 these, the results would have been less favorable. See the prospectus and financial statements for details. All results are historical and include the reinvestment of dividends and capital gains distributions. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS, AND THE PERFORMANCE SHOWN ABOVE DOES NOT REFLECT THE DEDUCTION OF TAXES, IF ANY, THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND SHARES. MARKET VOLATILITY CAN SIGNIFICANTLY AFFECT SHORT-TERM PERFORMANCE, AND MORE RECENT RETURNS MAY BE DIFFERENT FROM THOSE SHOWN. 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 - 8/31/03 - ----------------------------------------------------------------------------------------------------- The Portfolio of Investments is a complete list of all securities owned by your fund.

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 and may invest a substantial amount of its assets in issuers located in a single country or a limited number of countries. 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 - Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price 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. If no sales are reported, as is the case for most securities traded over the counter, securities are valued on the basis of quotations obtained from brokers and dealers or on the basis of valuations furnished by a pricing service. Short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes fair value as determined by the Board of Trustees. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. Portfolio investments for which market quotations are not readily available, or whose values have been materially affected by events occurring after the close of their primary markets, are valued at fair value as determined in good faith by or at the direction of the Board of Trustees. FOREIGN CURRENCY TRANSLATION - Investment valuations, other assets, and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. 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 generally accepted accounting principles. 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 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, wash sales and capital losses. The fund paid no distributions for the years ended August 31, 2003 and August 31, 2002. During the year ended August 31, 2003, accumulated net investment loss decreased by $10,310, accumulated net realized loss on investments and foreign currency transactions decreased by $2,041, and paid-in capital decreased by $12,351 due to differences between book and tax accounting for net investment losses and currency transactions. This change had no effect on the net assets or net asset value per share. At August 31, 2003, accumulated net investment loss and realized loss on investments and foreign currency transactions under book accounting were different from tax accounting due to temporary differences in accounting for currency, wash sales and capital losses. 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. The fund has a temporary expense reimbursement agreement whereby MFS has voluntarily agreed to pay all of the fund's operating expenses, exclusive of management, distribution, and service fees. The fund in turn will pay MFS an expense reimbursement fee not greater than 0.25% of average daily net assets. To the extent that the expense reimbursement fee exceeds the fund's actual expenses, the excess will be applied to amounts paid by MFS in prior years. The reimbursement plan expired on June 1, 2003. MFS instituted a new plan through January 1, 2004. At August 31, 2003, aggregate unreimbursed expenses amounted to $13,976. 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). On January 1, 2002, the Trustees terminated the Independent Trustee unfunded defined benefit plan for active Trustees and converted it to an unfunded retirement benefit deferral plan for active Trustees, which has no impact on the expense of the funds. Under the new plan, the unfunded pension liability was converted into an equivalent value of notional shares of the funds that will fluctuate with the performance of the funds. 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 at the following annual percentages 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 sales of Class A shares of the fund for the year ended August 31, 2003. 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: CLASS A Distribution Fee 0.10% ---------------------------------------------- Service Fee 0.25% ---------------------------------------------- Total Distribution Plan 0.35% ---------------------------------------------- The fund's payment of the 10% per annum Class A distribution fee and the 0.25% per annum Class A service fee are currently being waived by MFD. Certain Class A shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within 12 months following purchase. MFD receives all contingent deferred sales charges. There were no contingent deferred sales charges imposed on Class A shares during the year ended August 31, 2003. SHAREHOLDER SERVICING AGENT - MFSC, a wholly owned subsidiary of MFS, earns a fee 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%. Prior to April 1, 2003, the fee was 0.10% of the fund's average daily net assets. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $3,820,928 and $3,762,298, 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 $3,291,372 ---------------------------------------------- Gross unrealized appreciation $912,106 ---------------------------------------------- Gross unrealized depreciation (59,372) ---------------------------------------------- Net unrealized appreciation $852,734 ---------------------------------------------- (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: Year ended 8/31/03 Year ended 8/31/02 CLASS A SHARES SHARES AMOUNT SHARES AMOUNT Shares sold 7,249 $44,597 8,445 $56,345 - ------------------------------------------------------------------------------ Shares reacquired (431) (2,745) (8,132) (55,962) - ------------------------------------------------------------------------------ Net increase 6,818 $41,852 313 $383 - ------------------------------------------------------------------------------ Period ended 8/31/ Year ended 8/31/03 02* CLASS I SHARES SHARES AMOUNT SHARES AMOUNT Shares sold 62,702 $414,034 21,869 $149,439 - ------------------------------------------------------------------------------ Shares reacquired (63,841) (417,808) (2,580) (17,467) - ------------------------------------------------------------------------------ Net increase (decrease) (1,139) $(3,774) 19,289 $131,972 - ------------------------------------------------------------------------------ * For the period from the inception of Class I, July 31, 2002, through August 31, 2002. (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. 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 year ended August 31, 2003, was $24. The fund had no borrowings during the year. (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. - ------------------------------------------------------------------------------- INDEPENDENT AUDITORS' REPORT - ------------------------------------------------------------------------------- To the Trustees of MFS Series Trust I and Shareholders of MFS Japan Equity Fund: We have audited the accompanying statement of assets and liabilities of MFS Japan Equity Fund (the Fund) (one of the portfolios constituting MFS Series Trust I), including the portfolio of investments, as of August 31, 2003, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. Our procedures included confirmation of securities owned at August 31, 2003, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of MFS Japan Equity Fund at August 31, 2003, the results of its operations for the year then ended, the changes in its net assets for each of the two years then ended and its financial highlights for the periods indicated therein, in conformity with accounting principles generally accepted in the United States. /s/ ERNST & YOUNG LLP Boston, Massachusetts October 10, 2003 - ------------------------------------------------------------------------------ FEDERAL TAX INFORMATION (UNAUDITED) In January 2004, shareholders will be mailed a Form 1099-DIV reporting the federal tax status of all distributions paid during the calendar year 2003. The fund has the option to use equalization, which is a tax basis dividends paid deduction from earnings and profits distributed to shareholders upon redemption of shares. - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------------------------------------- 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.

Shames] Our firm was built on the philosophy that bottom-up fundamental research is the best means of achieving superior long-term investment performance. When you're managing billions of dollars for investors, we think you have an obligation to have in-depth, firsthand knowledge of every company owned, anywhere in the world. We have structured our equity and fixed-income investment teams to capitalize on the strength of our investment process and the global reach of our analysts based around the world. Our global research team is composed of 45 equity research analysts, 27 based in the United States and 18 based abroad, and 26 credit research analysts. Each analyst is assigned one or more specific industries and then charged with identifying the most attractive investment ideas within these industries. Our U.S. and non-U.S. equity research analysts are unified into one team that emphasizes a collaborative process in analyzing securities around the globe. Credit analysts also share their expertise in each segment of the fixed-income market and work as part of the same team ensuring that every member has access to information that may have a material effect on their investment decisions. As MFS(R) continues to grow and as markets become more complex, we believe our structure will enable us to maintain a consistent investment process with the goal of providing strong, long-term investment performance across market capitalizations, investment disciplines, and country borders for our investors. THINKING GLOBALLY More companies than ever compete globally and, therefore, we must make investment decisions knowing what is occurring outside of a company's local market. This trend plays to the strength of our environment of collaboration between our analysts and portfolio managers around the globe. The analysts know the most details about individual companies in specific industries and geographic regions. The portfolio managers have broader, cross-industry insights and a wider perspective on companies and industries. Our goal is to make sure those two sets of perspectives coordinate and work well together. As the world's markets become more interdependent, we believe our collaborative environment allows us to produce solid investment ideas for our portfolios. BUILDING A NETWORK Simply put, we believe our structure assures that our analysts maintain their peripheral vision rather than becoming too immersed in a specific segment of the market. We do not believe that analysts and portfolio managers - no matter how talented they may be - can succeed by working in a vacuum. Through the latest technology available, our entire research team meets frequently via video and telephone teleconferences, e-mail, and PDAs (personal digital assistants). When we hire new analysts, we require them to spend an average of one year in Boston to learn MFS' culture and to build relationships with their peers. We believe the interaction among our analysts is the key to making our collaborative process work toward delivering superior long-term investment performance for our investors. Our analysts work out of four research offices in Boston, London, Singapore, and Tokyo, and are assigned to specific regions and industries. They meet regularly with their colleagues to discuss world trends affecting the companies they cover. In addition, our equity and fixed-income analysts often visit company managements as a team. This collaboration is vital because of the different perspectives they bring to their analysis. Because a company's stock price has tended to follow its earnings over time, our equity research analysts tend to focus on gauging earnings potential, a company's position within its industry, and its ability to grow its market share. Conversely, our fixed-income analysts will look at stability of a company's cash flow, the value of its assets, and its capital structure to gauge whether the company can generate enough free cash flow to pay off its debt. As a result of their collaboration, we believe we're able to see a more complete view of a company. WORKING TOGETHER Our portfolio managers also work closely with the analysts to select the most appropriate securities for their portfolios from the various recommendations made by the analysts. Opinions are exchanged and ideas are challenged so that each member of our team is involved in our investment process. In fact, our portfolio managers will be the first ones to tell you that many of their best ideas start with the research analysts. We believe our collaborative approach also provides us with an effective way to assess risk. Our portfolio managers are not discouraged from taking on an appropriate level of risk; however, we have rigorous guidelines to assure that the level of risk is measured and monitored and consistent with the investment philosophies of each of our portfolios. All told, we believe our culture empowers the members of our investment team to continue to do their best work and allows them to make better investment decisions. As always, we appreciate your confidence in MFS and welcome any questions or comments you may have. Respectfully, /s/ Jeffrey L. Shames Jeffrey L. Shames Chairman MFS Investment Management(R) September 15, 2003 The opinions expressed in this letter are those of MFS and no forecasts can be guaranteed. - -------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - -------------------------------------------------------------------------------- THE HUMAN SIDE OF MONEY MANAGEMENT For nearly 80 years MFS has been offering investors clear paths to pursuing specific investment objectives.

For the past year, the value stocks that performed the best were typically higher-risk, lower-quality stocks in terms of balance sheet characteristics and/or earnings quality. Many of these stocks rebounded from very depressed, or in some cases, distressed levels in 2002. The rebound in lower-quality assets this year has been driven by improved access to capital as the U.S. Federal Reserve Board added liquidity to the banking system and eased financial pressures. While this fund seeks undervalued stocks, we have a quality focus and have historically invested in companies with solid balance sheets, good cash generation, and sustainable franchises throughout market cycles. This combination of value and quality has been important in driving the historical returns and lower volatility of the portfolio, but it has also led to relative underperformance during periods characterized by rebounds of low-quality assets. DETRACTORS FROM PERFORMANCE While the stocks in the portfolio generally performed well, our holdings in retail, utilities & communications, and leisure detracted the most from our performance relative to the fund's benchmark. In retail, our underperformance was due to our position in Sears last autumn. The stock declined after the company announced that the quality of its credit card portfolio was worse than the firm had previously known or disclosed. We reestablished a position in the stock this year after the company announced that it would sell the credit card business to focus more closely on restructuring its retail franchise. Our other holdings in retail, including Nike, Kroger, and Home Depot all performed well, but their performance was not enough to offset the relative underperformance of Sears. Nike and Home Depot were sold when they reached our performance target. In utilities, our emphasis on traditional, regulated gas and electric utilities, which represented good value in our view and offered premium yields, detracted from relative performance as the higher-beta power-merchant stocks rebounded from distressed levels in 2002. (Beta is a measure of a stock's historic level of risk relative to the market as a whole; the higher the beta is, the greater the risk.) In telecommunications, AT&T declined. While the company made significant progress in repairing its balance sheet through asset sales and restructuring, it was unable to capitalize on the troubles at competitor Worldcom, and that inability to do so disappointed investors. As the stock rebounded earlier this year, we eliminated our position. In the leisure sector, our holdings in more conservative publishing stocks such as Reed Elsevier and Gannett, both with strong balance sheets, healthy cash flows, and reasonable valuations, lagged the sector, which was led by more volatile cable, broadcasting, and gaming/recreation stocks. The fund no longer owns Gannett. Although our positioning in financial services did not detract from overall relative performance, our position in the Federal National Mortgage Association (Fannie Mae) was among the biggest detractors, offsetting gains elsewhere in the sector. Federal Home Loan Corporation's (Freddie Mac) restatement of past earnings raised concerns about increased regulatory scrutiny and its potential effect on both companies. We continue to have confidence in the quality of Fannie Mae's business and consider the stock's valuation attractive. The relative performance of the fund was also negatively affected by not owning J.P. Morgan Chase & Co. Even though the company's stock rose over the period, we had less confidence in its earnings power and balance sheet strength versus other financial holdings, such as Citigroup. CONTRIBUTORS TO PERFORMANCE The fund's positions in industrial goods & services contributed to performance, as did our underweighted position in autos and housing. In the industrial goods & services sector, our holdings in Caterpillar and Deere contributed to performance. Caterpillar and Deere improved profit margins during the period by cutting costs, reengineering manufacturing processes, and reducing manufacturing capacity. Although we were underweight in technology, our positions in Intel, Analog Devices, and Texas Instruments were among the most significant contributors to the portfolio's performance. Reasonable valuations and improving fundamentals in the semiconductor business, both PC and communications related, helped to drive these stocks higher. Both Intel and Analog Devices were sold when they reached our performance targets. Respectfully, /s/ Steven R. Gorham /s/ Lisa B. Nurme Steven R. Gorham Lisa B.

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 R 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. All performance results reflect any applicable expense subsidies and waivers in effect during the periods shown; without these, the results would have been less favorable. See the prospectus and financial statements for details. All results are historical and assume the reinvestment of dividends and capital gains. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS, AND THE PERFORMANCE SHOWN DOES NOT REFLECT THE DEDUCTION OF TAXES, IF ANY, THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND SHARES. MARKET VOLATILITY CAN SIGNIFICANTLY AFFECT SHORT-TERM PERFORMANCE, AND MORE RECENT RETURNS MAY BE DIFFERENT FROM THOSE SHOWN. VISIT WWW.MFS.COM FOR MORE CURRENT PERFORMANCE RESULTS.

See notes to financial statements. - ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS - ------------------------------------------------------------------------------- (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 - Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price 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. If no sales are reported, as is the case for most securities traded over the counter, securities are valued on the basis of quotations obtained from brokers and dealers or on the basis of valuations furnished by a pricing service. Short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes fair value as determined by the Board of Trustees. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. Portfolio investments for which market quotations are not readily available, or whose values have been materially affected by events occurring after the close of their primary markets, are valued at fair value as determined in good faith by or at the direction of the Board of Trustees. 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 - Investment valuations, other assets, and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. 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. Cash collateral is invested in short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the 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 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 period, the fund's custodian fees were reduced by $43,846 under this arrangement. The fund has entered into a directed brokerage agreement, under which the broker will credit the fund a portion of the commissions generated, to offset certain expenses of the fund. For the period, the fund's other expenses were reduced by $133,439 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 - ------------------------------------------------------------------------------ During the year ended August 31, 2003, accumulated undistributed net investment income decreased by $38,681, and accumulated net realized loss on investments and foreign currency transactions decreased by $65,959, and paid- in capital increased by $104,640 due to differences between book and tax accounting for currency transactions and real estate investment trusts. This change had no effect on the net assets or net asset value per share. 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) ----------------------------------------------------------- Unrealized appreciation 176,356,424 ----------------------------------------------------------- Post-October capital loss deferral (88,681,815) ----------------------------------------------------------- Other temporary differences (13,257) ----------------------------------------------------------- For federal income tax purposes, the capital loss carry forward 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). Post-October capital loss deferrals represent losses realized during the current fiscal year, but recognized for tax purposes in the next fiscal 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 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). On January 1, 2002, the Trustees terminated the Independent Trustee unfunded defined benefit plan for active Trustees. Included in Trustees' compensation is a pension expense of $1,577 for inactive trustees for the year ended August 31, 2003. 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 at the following annual percentages 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 $584,826 and $2,437 for the year ended August 31, 2003, 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 R, 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 R CLASS 529A CLASS 529B CLASS 529C Distribution Fee 0.10% 0.75% 0.75% 0.25% 0.25% 0.75% 0.75% - ----------------------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% 0.25% 0.25% 0.25% 0.25% - ----------------------------------------------------------------------------------------------------------------- Total Distribution Plan 0.35% 1.00% 1.00% 0.50% 0.50% 1.00% 1.00% - ----------------------------------------------------------------------------------------------------------------- MFD retains the service fee for accounts not attributable to a securities dealer, which for the year ended August 31, 2003, amounted to: CLASS A CLASS B CLASS C CLASS R CLASS 529A CLASS 529B CLASS 529C Service Fee Retained by MFD $395,515 $2,483 $3,686 $-- $213 $3 $-- - ----------------------------------------------------------------------------------------------------------------- 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. Fees incurred under the distribution plan during the year ended August 31, 2003, were as follows: CLASS A CLASS B CLASS C CLASS R CLASS 529A CLASS 529B CLASS 529C Total Distribution Plan 0.35% 1.00% 1.00% 0.50% 0.35% 1.00% 1.00% - ----------------------------------------------------------------------------------------------------------------- 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 Class 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 year ended August 31, 2003, were as follows: CLASS A CLASS B CLASS C CLASS 529B CLASS 529C Contingent Deferred Sales Charges Imposed $20,143 $2,354,232 $122,896 $-- $-- - -------------------------------------------------------------------------------- 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 - MFSC, a wholly owned subsidiary of MFS, earns a fee 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%. Prior to April 1, 2003, the fee was 0.10% of the fund's average daily net assets. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $3,514,403,906 and $2,088,011,260, 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 $5,124,261,711 -------------------------------------------------------- Gross unrealized appreciation $297,488,044 -------------------------------------------------------- Gross unrealized depreciation (121,115,827) -------------------------------------------------------- Net unrealized appreciation $176,372,217 -------------------------------------------------------- (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.

Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the bank's base rate. A commitment fee of $29,367 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 year. - ------------------------------------------------------------------------------- INDEPENDENT AUDITORS' REPORT - ------------------------------------------------------------------------------- To the Trustees of MFS Series Trust I and Shareholders of MFS Value Fund: We have audited the accompanying statement of assets and liabilities of MFS Value Fund (the Fund) (one of the portfolios constituting MFS Series Trust I), including the portfolio of investments, as of August 31, 2003, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. Our procedures included confirmation of securities owned at August 31, 2003, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of MFS Value Fund at August 31, 2003, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the periods indicated therein, in conformity with accounting principles generally accepted in the United States. /s/ ERNST & YOUNG LLP Boston, Massachusetts October 10, 2003 - -------------------------------------------------------------------------------------------------------------- TRUSTEES AND OFFICERS - -------------------------------------------------------------------------------------------------------------- The following tables present certain information regarding the Trustees and officers of the fund, 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.

Shames] Our firm was built on the philosophy that bottom-up fundamental research is the best means of achieving superior long-term investment performance. When you're managing billions of dollars for investors, we think you have an obligation to have in-depth, firsthand knowledge of every company owned, anywhere in the world. We have structured our equity and fixed-income investment teams to capitalize on the strength of our investment process and the global reach of our analysts based around the world. Our global research team is composed of 45 equity research analysts, 27 based in the United States and 18 based abroad, and 26 credit research analysts. Each analyst is assigned one or more specific industries and then charged with identifying the most attractive investment ideas within these industries. Our U.S. and non-U.S. equity research analysts are unified into one team that emphasizes a collaborative process in analyzing securities around the globe. Credit analysts also share their expertise in each segment of the fixed-income market and work as part of the same team ensuring that every member has access to information that may have a material effect on their investment decisions. As MFS(R) continues to grow and as markets become more complex, we believe our structure will enable us to maintain a consistent investment process with the goal of providing strong, long-term investment performance across market capitalizations, investment disciplines, and country borders for our investors. THINKING GLOBALLY More companies than ever compete globally and, therefore, we must make investment decisions knowing what is occurring outside of a company's local market. This trend plays to the strength of our environment of collaboration between our analysts and portfolio managers around the globe. The analysts know the most details about individual companies in specific industries and geographic regions. The portfolio managers have broader, cross-industry insights and a wider perspective on companies and industries. Our goal is to make sure those two sets of perspectives coordinate and work well together. As the world's markets become more interdependent, we believe our collaborative environment allows us to produce solid investment ideas for our portfolios. BUILDING A NETWORK Simply put, we believe our structure assures that our analysts maintain their peripheral vision rather than becoming too immersed in a specific segment of the market. We do not believe that analysts and portfolio managers - no matter how talented they may be - can succeed by working in a vacuum. Through the latest technology available, our entire research team meets frequently via video and telephone teleconferences, e-mail, and PDAs (personal digital assistants). When we hire new analysts, we require them to spend an average of one year in Boston to learn MFS' culture and to build relationships with their peers. We believe the interaction among our analysts is the key to making our collaborative process work toward delivering superior long-term investment performance for our investors. Our analysts work out of four research offices in Boston, London, Singapore, and Tokyo, and are assigned to specific regions and industries. They meet regularly with their colleagues to discuss world trends affecting the companies they cover. In addition, our equity and fixed-income analysts often visit company managements as a team. This collaboration is vital because of the different perspectives they bring to their analysis. Because a company's stock price has tended to follow its earnings over time, our equity research analysts tend to focus on gauging earnings potential, a company's position within its industry, and its ability to grow its market share. Conversely, our fixed-income analysts will look at stability of a company's cash flow, the value of its assets, and its capital structure to gauge whether the company can generate enough free cash flow to pay off its debt. As a result of their collaboration, we believe we're able to see a more complete view of a company. WORKING TOGETHER Our portfolio managers also work closely with the analysts to select the most appropriate securities for their portfolios from the various recommendations made by the analysts. Opinions are exchanged and ideas are challenged so that each member of our team is involved in our investment process. In fact, our portfolio managers will be the first ones to tell you that many of their best ideas start with the research analysts. We believe our collaborative approach also provides us with an effective way to assess risk. Our portfolio managers are not discouraged from taking on an appropriate level of risk; however, we have rigorous guidelines to assure that the level of risk is measured and monitored and consistent with the investment philosophies of each of our portfolios. All told, we believe our culture empowers the members of our investment team to continue to do their best work and allows them to make better investment decisions. As always, we appreciate your confidence in MFS and welcome any questions or comments you may have. Respectfully, /s/ Jeffrey L. Shames Jeffrey L. Shames Chairman MFS Investment Management(R) September 15, 2003 The opinions expressed in this letter are those of MFS and no forecasts can be guaranteed. - -------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - -------------------------------------------------------------------------------- THE HUMAN SIDE OF MONEY MANAGEMENT For nearly 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 12-month period ended August 31, 2003 proved extremely volatile but rewarding for patient, long-term investors. Nearly all asset classes showed positive performance for the period, and a second-quarter 2003 rally gave investors in U.S. stocks their best quarter in many years. CONTRIBUTORS TO PERFORMANCE The fund outperformed both its benchmark, the Russell 1000 Growth Index, and its Lipper large-cap growth peers over the period. Health care, consumer staples, and leisure were the fund's strongest sectors, relative to its benchmark. In health care, our emphasis on biotechnology concerns boosted returns. For example, Genentech shares climbed dramatically following the release of favorable test results for the company's colon cancer product, Avastin. This compound may be the first of a new generation of medications designed to combat cancer by cutting off blood supply to tumors. Genzyme, another biotech firm, successfully addressed an excess inventory issue involving its key drug, Renagel. In addition, the company won FDA approval for two drugs in its development pipeline. Fund results were also helped by our holding in Forest Laboratories, a pharmaceutical firm whose products include Lexapro and Celexa for the treatment of depression. Avoiding some disappointing names in the health care sector - including hospital giants Tenet Healthcare and HCA - also helped the portfolio's relative performance. The fund's significant underweighting in the consumer staples sector helped performance as the market favored stocks seen as less defensive issues. Especially during the second-quarter 2003 market rally, the fund benefited from not owning familiar names such as Coca-Cola, Procter & Gamble, and Anheuser-Busch - stocks that we felt did not fit our aggressive growth strategy and that, in fact, underperformed over the period. - ----------------------------------------------- TOP 5 STOCK HOLDINGS AS OF 8/31/03 MICROSOFT CORP. 4.2% Computer software and systems company - ----------------------------------------------- CISCO SYSTEMS, INC. 3.1% Computer networking firm - ----------------------------------------------- PFIZER, INC. 2.9% Pharmaceutical products company - ----------------------------------------------- WAL-MART STORES, INC. 2.3% General merchandise retailer - ----------------------------------------------- VIACOM, INC. 2.0% Diversified media and entertainment company - ----------------------------------------------- The portfolio is actively managed, and current holdings may be different. - ----------------------------------------------- Stock selection and an overweighted position among leisure companies also helped results during the period. Satellite TV broadcaster EchoStar Communications was our best-performing holding in the sector, as the company impressively expanded its subscriber base. Our positions in media and entertainment firms Clear Channel Communications, The Walt Disney Company, and Viacom benefited from an improving economy and an upturn in advertising spending. As the travel industry continued to recover and the restaurant business improved, we also profited from holdings in Starwood Hotels & Resorts Worldwide and Outback Steakhouse. In the financial services sector, the portfolio's focus on capital-markets- sensitive franchises such as Citigroup and Merrill Lynch helped performance as bond spreads narrowed, trading volumes rose, and security underwriting activity showed signs of renewed life. PERFORMANCE DETRACTORS While technology positions delivered strong absolute returns, portfolio performance in the sector lagged that of the Russell 1000 Growth Index. Our underweighted position among electronics makers generally, and Intel specifically, was chiefly responsible for constraining relative performance. Worries that weak corporate technology spending and excess capacity would dampen profits abated during the period, as inventories contracted and certain product markets, such as laptop PCs, showed surprising strength. In the business services arena, a number of holdings failed to meet our expectations over the period. Automatic Data Processing (ADP), for example, had previously dealt with a weak environment - soft demand for its payroll and financial services trade processing services - by cutting costs. In March of 2003, however, ADP management signaled that they would add back some incremental expenses and take some other actions that we felt could dampen future earnings growth potential. The stock fell on the news of the change in strategy, and we sold our position. Our holdings in travel reservations firm Sabre Holdings, which we sold, and financial services transaction processor BISYS Group also declined in price over the period. Respectfully, /s/ S. Irfan Ali S. Irfan Ali Portfolio Manager Note to Shareholders: Portfolio management is also assisted by Peggy W. Adams, Associate Portfolio Manager. Ms. Adams participates in the research process and strategy discussions, while the Portfolio Manager maintains overall responsibility for portfolio construction.

INDEX DEFINITION RUSSELL 1000 GROWTH INDEX - 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 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 J results, including sales charge, reflects the deduction of the maximum 3% sales charge and are available only to residents of Japan. Class R 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. All performance results reflect any applicable expense subsidies and waivers in effect during the periods shown; without these, the results would have been less favorable. See the prospectus and financial statements for details. All results are historical and assume the reinvestment of dividends and capital gains. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS, AND THE PERFORMANCE SHOWN DOES NOT REFLECT THE DEDUCTION OF TAXES, IF ANY, THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND SHARES. MARKET VOLATILITY CAN SIGNIFICANTLY AFFECT SHORT-TERM PERFORMANCE, AND MORE RECENT RETURNS MAY BE DIFFERENT FROM THOSE SHOWN. VISIT WWW.MFS.COM FOR MORE CURRENT PERFORMANCE RESULTS. 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 - ------------------------------------------------------------------------------- (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 - Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price 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. If no sales are reported, as is the case for most securities traded over the counter, securities are valued on the basis of quotations obtained from brokers and dealers or on the basis of valuations furnished by a pricing service. Short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes fair value as determined by the Board of Trustees. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. Portfolio investments for which market quotations are not readily available, or whose values have been materially affected by events occurring after the close of their primary markets, are valued at fair value as determined in good faith by or at the direction of the Board of Trustees. 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 - Investment valuations, other assets, and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. DEFERRED TRUSTEE COMPENSATION - Under a Deferred Compensation Plan (the Plan) independent Trustees may elect to defer receipt of all or a portion of their annual compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of the 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. 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 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. Cash collateral is invested in short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the 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 generally accepted accounting principles. 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 period, the fund's custodian fees were reduced by $16,238 under this arrangement. The fund has entered into a directed brokerage agreement, under which the broker will credit the fund a portion of the commissions generated, to offset certain expenses of the fund. For the period, the fund's other expenses were reduced by $98,677 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, real estate investment trusts, defaulted bonds, 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 - ------------------------------------------------------------------------------- During the year ended August 31, 2003, accumulated net investment loss decreased by $9,410,487, accumulated net realized loss on investments and foreign currency transactions increased by $8,375, and paid-in capital decreased by $9,402,112 due to differences between book and tax accounting for currency transactions and net operating losses. This change had no effect on the net assets or net asset value per share. 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) ------------------------------------------------------------- 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. 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). On January 1, 2002, the Trustees terminated the Independent Trustee unfunded defined benefit plan for active Trustees and converted it to an unfunded retirement benefit deferral plan for active Trustees. Under the new plan, the unfunded pension liability was converted into an equivalent value of notional shares of the fund that will fluctuate with the performance of the fund. Included in Trustees' compensation is a net decrease of $2,501 as a result of the change in the fund's pension liability under this plan and a pension expense of $2,544 for inactive trustees for the year ended August 31, 2003. 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 at the following annual percentages 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 $90,750 and $430 for the year ended August 31, 2003, 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 R, 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 financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. Our procedures included confirmation of securities owned at August 31, 2003, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of MFS Strategic Growth Fund at August 31, 2003, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the periods indicated therein, in conformity with accounting principles generally accepted in the United States. /s/ ERNST & YOUNG LLP Boston, Massachusetts October 10, 2003 - ------------------------------------------------------------------------------------------------------ TRUSTEES AND OFFICERS - ------------------------------------------------------------------------------------------------------ The following tables present certain information regarding the Trustees and officers of the fund, 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.

Shames] Our firm was built on the philosophy that bottom-up fundamental research is the best means of achieving superior long-term investment performance. When you're managing billions of dollars for investors, we think you have an obligation to have in-depth, firsthand knowledge of every company owned, anywhere in the world. We have structured our equity and fixed-income investment teams to capitalize on the strength of our investment process and the global reach of our analysts based around the world. Our global research team is composed of 45 equity research analysts, 27 based in the United States and 18 based abroad, and 26 credit research analysts. Each analyst is assigned one or more specific industries and then charged with identifying the most attractive investment ideas within these industries. Our U.S. and non-U.S. equity research analysts are unified into one team that emphasizes a collaborative process in analyzing securities around the globe. Credit analysts also share their expertise in each segment of the fixed-income market and work as part of the same team ensuring that every member has access to information that may have a material effect on their investment decisions. As MFS(R) continues to grow and as markets become more complex, we believe our structure will enable us to maintain a consistent investment process with the goal of providing strong, long-term investment performance across market capitalizations, investment disciplines, and country borders for our investors. THINKING GLOBALLY More companies than ever compete globally and, therefore, we must make investment decisions knowing what is occurring outside of a company's local market. This trend plays to the strength of our environment of collaboration between our analysts and portfolio managers around the globe. The analysts know the most details about individual companies in specific industries and geographic regions. The portfolio managers have broader, cross-industry insights and a wider perspective on companies and industries. Our goal is to make sure those two sets of perspectives coordinate and work well together. As the world's markets become more interdependent, we believe our collaborative environment allows us to produce solid investment ideas for our portfolios. BUILDING A NETWORK Simply put, we believe our structure assures that our analysts maintain their peripheral vision rather than becoming too immersed in a specific segment of the market. We do not believe that analysts and portfolio managers - no matter how talented they may be - can succeed by working in a vacuum. Through the latest technology available, our entire research team meets frequently via video and telephone teleconferences, e-mail, and PDAs (personal digital assistants). When we hire new analysts, we require them to spend an average of one year in Boston to learn MFS' culture and to build relationships with their peers. We believe the interaction among our analysts is the key to making our collaborative process work toward delivering superior long-term investment performance for our investors. Our analysts work out of four research offices in Boston, London, Singapore, and Tokyo, and are assigned to specific regions and industries. They meet regularly with their colleagues to discuss world trends affecting the companies they cover. In addition, our equity and fixed-income analysts often visit company managements as a team. This collaboration is vital because of the different perspectives they bring to their analysis. Because a company's stock price has tended to follow its earnings over time, our equity research analysts tend to focus on gauging earnings potential, a company's position within its industry, and its ability to grow its market share. Conversely, our fixed-income analysts will look at stability of a company's cash flow, the value of its assets, and its capital structure to gauge whether the company can generate enough free cash flow to pay off its debt. As a result of their collaboration, we believe we're able to see a more complete view of a company. WORKING TOGETHER Our portfolio managers also work closely with the analysts to select the most appropriate securities for their portfolios from the various recommendations made by the analysts. Opinions are exchanged and ideas are challenged so that each member of our team is involved in our investment process. In fact, our portfolio managers will be the first ones to tell you that many of their best ideas start with the research analysts. We believe our collaborative approach also provides us with an effective way to assess risk. Our portfolio managers are not discouraged from taking on an appropriate level of risk; however, we have rigorous guidelines to assure that the level of risk is measured and monitored and consistent with the investment philosophies of each of our portfolios. All told, we believe our culture empowers the members of our investment team to continue to do their best work and allows them to make better investment decisions. As always, we appreciate your confidence in MFS and welcome any questions or comments you may have. Respectfully, /s/ Jeffrey L. Shames Jeffrey L. Shames Chairman MFS Investment Management(R) September 15, 2003 The opinions expressed in this letter are those of MFS and no forecasts can be guaranteed. - -------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - -------------------------------------------------------------------------------- THE HUMAN SIDE OF MONEY MANAGEMENT For nearly 80 years MFS has been offering investors clear paths to pursuing specific investment objectives.

High levels of jobless claims, volatile energy prices, and the war in Iraq all constrained business and consumer spending. However, once the war in Iraq was declared at an end, confidence in U.S. markets began to return. After holding short-term interest rates steady for most of 2002, the U.S. Federal Reserve Board (the Fed) unanimously decided to cut short-term rates 50 basis points (0.50%) in November. The Fed stated that the cut was necessary because uncertainty was inhibiting spending, production, and employment. It then held short-term interest rates steady through June 24, 2003. On June 25 citing continued mixed economic data, the Fed cut the federal funds rate by 25 basis points (0.25%) to 1.00%. SUPPLY AND DEMAND Throughout much of the period, commercial paper was in short supply. The precarious nature of the economy caused companies to cut costs by reducing overhead, cutting the size of their workforce, and pulling back on merger and acquisition activity. As a result, companies had less need to finance debt through the commercial paper market, and supplies of commercial paper became limited. However, demand for all types of high-quality short-term debt, including commercial paper, remained strong. FUND POSITIONING Until the Fed's interest rate cut in June, we had targeted an average maturity for the portfolio at about 50 days. After the cut, we revised our target maturity to 40 to 45 days. Generally low interest rates throughout the period led us to concentrate portfolio investments in high-quality commercial paper and asset-backed commercial paper. These short-term obligations typically yielded three to five basis points (0.03% to 0.05%) more than discount agency paper of similar maturity. On August 31, 2003, approximately 82% of the portfolio was invested in commercial paper and asset-backed commercial paper. The balance of the portfolio was invested in U.S. government and government-guaranteed issues. Regardless of market or economic conditions, we will maintain the portfolio's high quality as we focus on the portfolio's objectives of income, capital preservation and liquidity.

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. All performance results reflect any applicable expense subsidies and waivers in effect during the periods shown; without these, the results would have been less favorable. See the prospectus and financial statements for details. All results are historical and assume the reinvestment of dividends and capital gains. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS, AND THE PERFORMANCE SHOWN DOES NOT REFLECT THE DEDUCTION OF TAXES, IF ANY, THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND SHARES. MARKET VOLATILITY CAN SIGNIFICANTLY AFFECT SHORT-TERM PERFORMANCE, AND MORE RECENT RETURNS MAY BE DIFFERENT FROM THOSE SHOWN. VISIT WWW.MFS.COM FOR MORE CURRENT PERFORMANCE RESULTS.

See notes to financial statements. - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- (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. Portfolio investments for which market quotations are not readily available, or whose values have been materially affected by events occurring after the close of their primary markets, are valued at fair value as determined in good faith by or at the direction of the Board of Trustees. 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 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. 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 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 0.55% 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 year ended August 31, 2003 were 0.45% 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). Included in Trustees' compensation is a pension expense of $5,433 for inactive trustees for the year ended August 31, 2003. 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 at the following annual percentages of the 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 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 year ended August 31, 2003, amounted to: CLASS A CLASS B CLASS C CLASS 529A CLASS 529B CLASS 529C Service Fee Retained by MFD $-- $12,606 $10,143 $-- $-- $-- - ----------------------------------------------------------------------------------------------- Fees incurred under the distribution plan during the year ended August 31, 2003, were as follows: CLASS A CLASS B CLASS C CLASS 529A CLASS 529B CLASS 529C Total Distribution Plan 0.00% 0.64% 0.65% 0.00% 0.29% 0.26% - ----------------------------------------------------------------------------------------------- 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 year ended August 31, 2003, were as follows: CLASS A CLASS B CLASS C CLASS 529B CLASS 529C Contingent Deferred Sales Charges Imposed $147,728 $4,347,593 $88,997 $-- $-- - -------------------------------------------------------------------------------- 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 - MFSC, a wholly owned subsidiary of MFS, earns a fee 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%. Prior to April 1, 2003, the fee was 0.10% of the fund's average daily net assets. (4) PORTFOLIO SECURITIES Purchases and sales of investments, exclusive of securities subject to repurchase agreements, aggregated $31,547,751,855 and $31,717,989,168, respectively.

These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audit. We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of August 31, 2003, by correspondence with the custodian and brokers. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion. In our opinion, such financial statements present fairly, in all material respects, the financial position of MFS Cash Reserve Fund as of August 31, 2003, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Shames] Our firm was built on the philosophy that bottom-up fundamental research is the best means of achieving superior long-term investment performance. When you're managing billions of dollars for investors, we think you have an obligation to have in-depth, firsthand knowledge of every company owned, anywhere in the world. We have structured our equity and fixed-income investment teams to capitalize on the strength of our investment process and the global reach of our analysts based around the world. Our global research team is composed of 45 equity research analysts, 27 based in the United States and 18 based abroad, and 26 credit research analysts. Each analyst is assigned one or more specific industries and then charged with identifying the most attractive investment ideas within these industries. Our U.S. and non-U.S. equity research analysts are unified into one team that emphasizes a collaborative process in analyzing securities around the globe. Credit analysts also share their expertise in each segment of the fixed-income market and work as part of the same team ensuring that every member has access to information that may have a material effect on their investment decisions. As MFS(R) continues to grow and as markets become more complex, we believe our structure will enable us to maintain a consistent investment process with the goal of providing strong, long-term investment performance across market capitalizations, investment disciplines, and country borders for our investors. THINKING GLOBALLY More companies than ever compete globally and, therefore, we must make investment decisions knowing what is occurring outside of a company's local market. This trend plays to the strength of our environment of collaboration between our analysts and portfolio managers around the globe. The analysts know the most details about individual companies in specific industries and geographic regions. The portfolio managers have broader, cross-industry insights and a wider perspective on companies and industries. Our goal is to make sure those two sets of perspectives coordinate and work well together. As the world's markets become more interdependent, we believe our collaborative environment allows us to produce solid investment ideas for our portfolios. BUILDING A NETWORK Simply put, we believe our structure assures that our analysts maintain their peripheral vision rather than becoming too immersed in a specific segment of the market. We do not believe that analysts and portfolio managers - no matter how talented they may be - can succeed by working in a vacuum. Through the latest technology available, our entire research team meets frequently via video and telephone teleconferences, e-mail, and PDAs (personal digital assistants). When we hire new analysts, we require them to spend an average of one year in Boston to learn MFS' culture and to build relationships with their peers. We believe the interaction among our analysts is the key to making our collaborative process work toward delivering superior long-term investment performance for our investors. Our analysts work out of four research offices in Boston, London, Singapore, and Tokyo, and are assigned to specific regions and industries. They meet regularly with their colleagues to discuss world trends affecting the companies they cover. In addition, our equity and fixed-income analysts often visit company managements as a team. This collaboration is vital because of the different perspectives they bring to their analysis. Because a company's stock price has tended to follow its earnings over time, our equity research analysts tend to focus on gauging earnings potential, a company's position within its industry, and its ability to grow its market share. Conversely, our fixed-income analysts will look at stability of a company's cash flow, the value of its assets, and its capital structure to gauge whether the company can generate enough free cash flow to pay off its debt. As a result of their collaboration, we believe we're able to see a more complete view of a company. WORKING TOGETHER Our portfolio managers also work closely with the analysts to select the most appropriate securities for their portfolios from the various recommendations made by the analysts. Opinions are exchanged and ideas are challenged so that each member of our team is involved in our investment process. In fact, our portfolio managers will be the first ones to tell you that many of their best ideas start with the research analysts. We believe our collaborative approach also provides us with an effective way to assess risk. Our portfolio managers are not discouraged from taking on an appropriate level of risk; however, we have rigorous guidelines to assure that the level of risk is measured and monitored and consistent with the investment philosophies of each of our portfolios. All told, we believe our culture empowers the members of our investment team to continue to do their best work and allows them to make better investment decisions. As always, we appreciate your confidence in MFS and welcome any questions or comments you may have. Respectfully, /s/ Jeffrey L. Shames Jeffrey L. Shames Chairman MFS Investment Management(R) September 15, 2003 The opinions expressed in this letter are those of MFS and no forecasts can be guaranteed. - -------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - -------------------------------------------------------------------------------- MFS Original Research THE HUMAN SIDE OF MONEY MANAGEMENT For nearly 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 12-month period ended August 31, 2003, proved extremely volatile but rewarding for patient, long-term investors. Nearly all asset classes showed positive performance for the period, and a second-quarter 2003 rally gave investors in U.S. stocks their best quarter in many years. In retrospect, the stock market appears to us to have bottomed in the September 2002 to March 2003 time frame, driven down largely by a weak economy, corporate scandals, and geopolitical uncertainty over Iraq and North Korea. As major fighting ended in Iraq and investors became more confident in the market, we believe there was an important shift in investor sentiment. There appeared to be a return to a more rational view of stock values, one that stood in stark contrast to the exuberance that dominated the market from about 1998 to 2000 and the fear that seemed the primary motivation for investors for the three years that followed. It appears to us that, toward the end of the period, the market was being driven more by company fundamentals - basic business factors such as earnings and cash flow growth - than we have seen in some time. DETRACTORS FROM PERFORMANCE While fund performance was positive for the period, we did not fully participate in the market's gains; the portfolio underperformed its benchmark, the Russell 1000 Growth Index, and its Lipper large cap growth peers. The fund's relatively cautious stance among technology stocks in general, and makers of electronics specifically, was the biggest detractor from performance during the period. Worries that weak corporate technology spending and excess capacity would dampen profits abated during the period, as inventories contracted and certain product markets, such as laptop PCs, showed surprising strength. Our holding in Analog Devices clearly benefited from this shift; however, that gain was more than offset by our underweighted positions in semiconductor titans such as Intel. ----------------------------------------------- TOP 5 STOCK HOLDINGS AS OF 8/31/03 MICROSOFT CORP. 4.0% Computer software and systems company ----------------------------------------------- WAL-MART STORES, INC. 2.9% General merchandise retailer ----------------------------------------------- VIACOM, INC. 2.7% Diversified media and entertainment company ----------------------------------------------- TARGET CORP. 2.5% General merchandise retailer ----------------------------------------------- INTEL CORP. 2.2% Semiconductor manufacturer ----------------------------------------------- The portfolio is actively managed, and current holdings may be different. ----------------------------------------------- Positioning among industrial goods and services firms also detracted from results. Our holding in Northrop Grumman was noteworthy in this regard. Northrop's stock lost traction during the period as a number of one-time charges masked otherwise good operating performance. The fund's shares in Lockheed Martin also fell in price and were sold out of the portfolio. Our holding in hospital firm Tenet Healthcare also detracted from results. Its shares fell on news that the firm had increased revenues by using a loophole in Medicare regulations. In the business services area, our position in payroll and transaction processor Automatic Data Processing also hurt performance. CONTRIBUTORS TO PERFORMANCE Health care, consumer staples, and financial services were the fund's strongest sectors, relative to its benchmark. In health care, results were helped by our holding in Forest Laboratories, a pharmaceutical firm whose products include Lexapro and Celexa for the treatment of depression. Our emphasis on biotechnology concerns also boosted returns. For example, Genentech shares climbed dramatically following the release of favorable test results for the company's colon cancer product, Avastin. This compound may be the first of a new generation of medications designed to combat cancer by cutting off blood supply to tumors. Amgen was another strong contributor in the biotech area. In the consumer staples sector, stock selection and a relative underweighting helped performance. Our Avon position performed well as the company's sales leadership and supply chain initiatives boosted both revenue and earnings growth. As more defensive consumer staples stocks began to fall out of favor, especially during the second-quarter 2003 rally, the fund benefited from not owning Kimberly Clark and from largely avoiding Coca-Cola, which was not held in the portfolio at period end. In the financial services sector, the portfolio's focus on capital-markets- sensitive franchises such as Goldman Sachs helped performance as bond spreads narrowed, trading volumes rose, and security underwriting activity showed signs of renewed life. The fund's positions in home loan provider Fannie Mae and student loan provider SLM Corp. also added to results.

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 R 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. All performance results reflect any applicable expense subsidies and waivers in effect during the periods shown; without these, the results would have been less favorable. See the prospectus and financial statements for details. All results are historical and assume the reinvestment of dividends and capital gains. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS, AND THE PERFORMANCE SHOWN DOES NOT REFLECT THE DEDUCTION OF TAXES, IF ANY, THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND SHARES. MARKET VOLATILITY CAN SIGNIFICANTLY AFFECT SHORT-TERM PERFORMANCE, AND MORE RECENT RETURNS MAY BE DIFFERENT FROM THOSE SHOWN. VISIT WWW.MFS.COM FOR MORE CURRENT PERFORMANCE RESULTS. 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.

See notes to financial statements. - ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS - ------------------------------------------------------------------------------- (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 - Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price 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. If no sales are reported, as is the case for most securities traded over the counter, securities are valued on the basis of quotations obtained from brokers and dealers or on the basis of valuations furnished by a pricing service. All other securities (other than short-term obligations), in the fund's portfolio for which the principal market is one or more securities or commodities exchanges (whether domestic or foreign) will be valued at the last reported sale price or at the settlement price prior to the determination (or if there has been no current sale, at the closing bid price) on the primary exchange on which such securities are traded; but if a securities exchange is not the principal market for securities, such securities will, if market quotations are readily available, be valued at current bid prices. Short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes fair value as determined by the Board of Trustees. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. Portfolio investments for which market quotations are not readily available, or whose values have been materially affected by events occurring after the close of their primary markets, are valued at fair value as determined in good faith by or at the direction of the Board of Trustees. 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 - Investment valuations, other assets, and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. 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. Cash collateral is invested in short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the 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 agents. 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 generally accepted accounting principles. 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. Some securities may be purchased on a "when-issued" or "forward delivery" basis, which means that the securities will be delivered to the fund at a future date, usually beyond customary settlement time. 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 period, the fund's custodian fees were reduced by $7,116 under this arrangement. The fund has entered into a directed brokerage agreement, under which the broker will credit the fund a portion of the commissions generated, to offset certain expenses of the fund. For the period, the fund's other expenses were reduced by $165,345 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. During the year ended August 31, 2003, accumulated net investment loss decreased by $4,756,738, accumulated net realized loss on investments and foreign currency transactions decreased by $54,059, and paid-in capital decreased by $4,810,797 due to differences between book and tax accounting for currency transactions, and net operating losses. This change had no effect on the net assets or net asset value per share. As of August 31, 2003, the components of accumulated losses on a tax basis were as follows: Undistributed ordinary income $-- ------------------------------------------------------------------ Undistributed long-term capital gain -- ------------------------------------------------------------------ Capital loss carryforward (176,659,316) ------------------------------------------------------------------ Unrealized appreciation 64,564,891 ------------------------------------------------------------------ Post October capital loss deferred (20,420,083) ------------------------------------------------------------------ Post October currency loss deferred (57,490) ------------------------------------------------------------------ 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. 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 inactive trustees and an unfunded retirement benefit deferral plan for active trustees. Included in Trustees' compensation is a net decrease of $3,733 as a result of the change in the fund's pension liability for active Trustees and a pension expense of $7,481 for inactive trustees for the year ended August 31, 2003. 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 at the following annual percentages 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 $116,858 for the year ended August 31, 2003, 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 and Class R 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 R Distribution Fee 0.10% 0.75% 0.75% 0.25% - ---------------------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% 0.25% - ---------------------------------------------------------------------------------------------------------------- Total Distribution Plan 0.35% 1.00% 1.00% 0.50% - ---------------------------------------------------------------------------------------------------------------- MFD retains the service fee for accounts not attributable to a securities dealer, which for the year ended August 31, 2003, amounted to: CLASS A CLASS B CLASS C CLASS R Service Fee Retained by MFD $48,489 $255 $730 $0 - ---------------------------------------------------------------------------------------------------------------- Fees incurred under the distribution plan during the year ended August 31, 2003, were as follows: CLASS A CLASS B CLASS C CLASS R Total Distribution Plan 0.35% 1.00% 1.00% 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 year ended August 31, 2003, were as follows: CLASS A CLASS B CLASS C Contingent Deferred Sales Charges Imposed $2,268 $316,421 $33,224 - ------------------------------------------------------------------------------- SHAREHOLDER SERVICING AGENT - MFSC, a wholly owned subsidiary of MFS, earns a fee 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%. Prior to April 1, 2003, the fee was 0.10% of the fund's average daily net assets. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $2,099,310,650 and $2,017,458,441, 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 $738,747,623 ------------------------------------------------------------------ Gross unrealized appreciation $116,377,794 ------------------------------------------------------------------ Gross unrealized depreciation (51,812,580) ------------------------------------------------------------------ Net unrealized appreciation $64,565,214 ------------------------------------------------------------------ (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.

Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the bank's base rate. A commitment fee of $4,625 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 year. - ------------------------------------------------------------------------------- INDEPENDENT AUDITORS' REPORT - ------------------------------------------------------------------------------- To the Trustees of MFS Series Trust I and Shareholders of MFS Core Growth Fund: We have audited the accompanying statement of assets and liabilities of MFS Core Growth Fund (the Fund) (one of the portfolios constituting MFS Series Trust I), including the portfolio of investments, as of August 31, 2003, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. Our procedures included confirmation of securities owned at August 31, 2003, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of MFS Core Growth Fund at August 31, 2003, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the periods indicated therein, in conformity with accounting principles generally accepted in the United States.

Shames] Our firm was built on the philosophy that bottom-up fundamental research is the best means of achieving superior long-term investment performance. When you're managing billions of dollars for investors, we think you have an obligation to have in-depth, firsthand knowledge of every company owned, anywhere in the world. We have structured our equity and fixed-income investment teams to capitalize on the strength of our investment process and the global reach of our analysts based around the world. Our global research team is composed of 45 equity research analysts, 27 based in the United States and 18 based abroad, and 26 credit research analysts. Each analyst is assigned one or more specific industries and then charged with identifying the most attractive investment ideas within these industries. Our U.S. and non-U.S. equity research analysts are unified into one team that emphasizes a collaborative process in analyzing securities around the globe. Credit analysts also share their expertise in each segment of the fixed-income market and work as part of the same team ensuring that every member has access to information that may have a material effect on their investment decisions. As MFS(R) continues to grow and as markets become more complex, we believe our structure will enable us to maintain a consistent investment process with the goal of providing strong, long-term investment performance across market capitalizations, investment disciplines, and country borders for our investors. THINKING GLOBALLY More companies than ever compete globally and, therefore, we must make investment decisions knowing what is occurring outside of a company's local market. This trend plays to the strength of our environment of collaboration between our analysts and portfolio managers around the globe. The analysts know the most details about individual companies in specific industries and geographic regions. The portfolio managers have broader, cross-industry insights and a wider perspective on companies and industries. Our goal is to make sure those two sets of perspectives coordinate and work well together. As the world's markets become more interdependent, we believe our collaborative environment allows us to produce solid investment ideas for our portfolios. BUILDING A NETWORK Simply put, we believe our structure assures that our analysts maintain their peripheral vision rather than becoming too immersed in a specific segment of the market. We do not believe that analysts and portfolio managers - no matter how talented they may be - can succeed by working in a vacuum. Through the latest technology available, our entire research team meets frequently via video and telephone teleconferences, e-mail, and PDAs (personal digital assistants). When we hire new analysts, we require them to spend an average of one year in Boston to learn MFS' culture and to build relationships with their peers. We believe the interaction among our analysts is the key to making our collaborative process work toward delivering superior long-term investment performance for our investors. Our analysts work out of four research offices in Boston, London, Singapore, and Tokyo, and are assigned to specific regions and industries. They meet regularly with their colleagues to discuss world trends affecting the companies they cover. In addition, our equity and fixed-income analysts often visit company managements as a team. This collaboration is vital because of the different perspectives they bring to their analysis. Because a company's stock price has tended to follow its earnings over time, our equity research analysts tend to focus on gauging earnings potential, a company's position within its industry, and its ability to grow its market share. Conversely, our fixed-income analysts will look at stability of a company's cash flow, the value of its assets, and its capital structure to gauge whether the company can generate enough free cash flow to pay off its debt. As a result of their collaboration, we believe we're able to see a more complete view of a company. WORKING TOGETHER Our portfolio managers also work closely with the analysts to select the most appropriate securities for their portfolios from the various recommendations made by the analysts. Opinions are exchanged and ideas are challenged so that each member of our team is involved in our investment process. In fact, our portfolio managers will be the first ones to tell you that many of their best ideas start with the research analysts. We believe our collaborative approach also provides us with an effective way to assess risk. Our portfolio managers are not discouraged from taking on an appropriate level of risk; however, we have rigorous guidelines to assure that the level of risk is measured and monitored and consistent with the investment philosophies of each of our portfolios. All told, we believe our culture empowers the members of our investment team to continue to do their best work and allows them to make better investment decisions. As always, we appreciate your confidence in MFS and welcome any questions or comments you may have. Respectfully, /s/ Jeffrey L. Shames Jeffrey L. Shames Chairman MFS Investment Management(R) September 15, 2003 The opinions expressed in this letter are those of MFS and no forecasts can be guaranteed. - -------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - -------------------------------------------------------------------------------- THE HUMAN SIDE OF MONEY MANAGEMENT For nearly 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 twelve-month reporting period was marked by extreme volatility but, in the end, rewarded long-term investors with better results than they had experienced in quite some time. Nearly all asset classes showed positive performance for the period, and a second-quarter 2003 rally gave investors in U.S. stocks their best quarter in many years. Modest economic improvements and slightly stronger corporate earnings sparked a stock market rally in October and November 2002. The stock markets cooled in the early months of 2003 because of mixed economic signals and an increase in geopolitical tensions. However, the market began a rebound in mid-March that continued almost without pause for the balance of the reporting period. Technology and utilities & communications were among the market's leaders during the rallies. DETRACTORS TO PERFORMANCE Health care, primarily pharmaceuticals, and technology stocks were the most significant detractors to relative performance for the period. The pharmaceutical industry continued to be plagued by investor indifference towards the sector. The group, normally considered to be a defensive investment - people will pay to stay healthy even in a recession - was rocked by successful challenges to long-standing patents. Those trends emboldened generic pharmaceutical companies to increase the number of challenges. As a result, the stock prices of pharmaceutical firms such as AstraZeneca and Novartis became more volatile when faced with patent challenges during the period. As of the end of the period, we continue to believe that AstraZeneca and Novartis have solid product lines and have a number of drugs in development that show good promise. - -------------------------------------------------- TOP 5 STOCK HOLDINGS AS OF 8/31/03 NOVARTIS AG 3.6% Swiss pharmaceutical company - -------------------------------------------------- ASTRAZENECA GROUP PLC 3.2% Pharmaceuticals manufacturer - -------------------------------------------------- TOTAL S.A. 2.9% French oil and petrochemical company - -------------------------------------------------- THE ROYAL BANK OF SCOTLAND GROUP 2.9% Banking firm with operations in the United Kingdom and the United States - -------------------------------------------------- BROTHER INDUSTRIES 2.5% Japanese manufacturer of sewing machines, home computers, printer - -------------------------------------------------- The portfolio is actively managed, and current holdings may be different. - -------------------------------------------------- Separately in health care, Jomed, a heart-care surgical products company, was a significant detractor from performance. The company's financial position was overstated through improper accounting. When the company disclosed that it had booked revenues for products it hadn't sold, the stock plummeted. The fund no longer owns this stock. The fund was underweighted in technology, relative to its benchmark, and that weighting detracted from relative performance because the sector was one of the strongest performing groups in the market rally. Fund performance was also hurt by not owning Nokia and disappointing results from Tandberg, a company that had performed well for us in the past. Tandberg is a videoconferencing company that had enjoyed high, double-digit growth for many periods. When the company announced that it would not meet growth expectations, its stock price fell. The fund no longer owns this stock. The stocks of cosmetics manufacturer Shiseido and videogame software maker Sega were also sold from the portfolio because of disappointing performance. Although Shiseido had improved profitability by consolidating its product lines, the company's sales weakened as a result of the global economic slowdown. In 2002, Sega had high hopes for the launch of new video games during the second half of the year. The expected sales for the games did not materialize. Investors further pushed down Sega's stock price when it announced that it was purchasing one of its competitors. CONTRIBUTORS TO PERFORMANCE Retailing and the utilities & communications sectors turned in strong returns during the reporting period after struggling during the global economic slowdown in 2002. Fund performance was also helped by strong stock selection in the automobile industry. Chinese power company Huaneng Power, Japanese telecommunications company KDDI, and France Telecom led performance for the utilities & communications sector. Huaneng's stock price climbed as Chinese demand for power continued to expand. KDDI's stock price rose as a result, we think, of investors' focus on the company's potential for better profit margins and its cost-cutting efforts. The strong performance of Dutch telecommunications company, Kon KPN is emblematic of the rebound in many telecommunication companies' stock prices. Consolidation in the industry, substantial balance sheet repairs, and more rational spending practices made this and other telecommunications companies much stronger and their earnings estimates have improved as a result. Stock selection in retailing made a significant difference to fund performance for the period. Two stocks, in particular, contributed healthy returns to the portfolio: British retailers Kingfisher and Next. Kingfisher is a do-it- yourself retailer that cut costs and spun off its electrical business so that it could focus on its core business. Kingfisher benefited from strong sales in both its British and French stores. The stock of Next, a clothing retailer, rose largely, in our view, on investor confidence in the British consumer. Nissan and Stanley Electric were strong individual contributors to fund performance. Nissan had successfully introduced many new models, especially in the light truck area where it cut into the market share of U.S. automakers. The company demonstrated a better feel for the U.S. consumer than it had shown previously and that fact was reflected in its sales. We sold this stock when it reached our price target. Stanley Electric supplies high intensity headlights to the automobile industry as well as light emitting display (LEDs) units. Strong demand for these products boosted the shares. /s/ David A.

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 R 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. All performance results reflect any applicable expense subsidies and waivers in effect during the periods shown; without these, the results would have been less favorable. See the prospectus and financial statements for details. All results are historical and assume the reinvestment of dividends and capital gains. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS, AND THE PERFORMANCE SHOWN DOES NOT REFLECT THE DEDUCTION OF TAXES, IF ANY, THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND SHARES. MARKET VOLATILITY CAN SIGNIFICANTLY AFFECT SHORT-TERM PERFORMANCE, AND MORE RECENT RETURNS MAY BE DIFFERENT FROM THOSE SHOWN. VISIT WWW.MFS.COM FOR MORE CURRENT PERFORMANCE RESULTS. 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.

See notes to financial statements. - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- (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 - Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price 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. If no sales are reported, as is the case for most securities traded over the counter, securities are valued on the basis of quotations obtained from brokers and dealers or on the basis of valuations furnished by a pricing service. Short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes fair value as determined by the Board of Trustees. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. Portfolio investments for which market quotations are not readily available, or whose values have been materially affected by events occurring after the close of their primary markets, are valued at fair value as determined in good faith by or at the direction of the Board of Trustees. 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 - Investment valuations, other assets, and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. 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. Cash collateral is invested in short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the 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 generally accepted accounting principles. 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 period, the fund's custodian fees were reduced by $6,067 under this arrangement. The fund has entered into a directed brokerage agreement, under which the broker will credit the fund a portion of the commissions generated, to offset certain expenses of the fund. For the period, the fund's other expenses were reduced by $19,800 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, 2002 and August 31, 2003. During the year ended August 31, 2003, accumulated undistributed net investment income decreased by $539,004, accumulated net realized loss on investments and foreign currency transactions decreased by $538,249 and paid- in capital increased by $755 due to differences between book and tax accounting for currency transactions and passive foreign investment companies. This change had no effect on the net assets or net asset value per share. 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 - -------------------------------------------------------------------------------- Undistributed long-term capital gain -- - -------------------------------------------------------------------------------- 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, and program manager 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 1.00% of the fund's average daily net assets. The fund has a temporary expense reimbursement agreement whereby MFS has contractually agreed to pay all of the fund's operating expenses, exclusive of management, distribution, and service fees. The fund in turn will pay 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 R and not greater than 0.65% of average daily net assets for Class 529A, Class 529B and Class 529C. To the extent that the expense reimbursement fee exceeds the fund's actual expenses, the excess will be applied to amounts paid by MFS in prior years. At August 31, 2003, aggregate unreimbursed expenses amounted to $1,222,627. 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 inactive trustees and an unfunded retirement benefit deferral plan for active trustees. Included in Trustee's compensation is a net decrease of $3,015 as a result of the change in the fund's pension liability for active trustees and a pension expense of $592 for inactive trustees for the year ended August 31, 2003. 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 at the following annual percentages 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 $56,769 and $474 for the year ended August 31, 2003, 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 R, 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.

Contingent deferred sales charges imposed during the year ended August 31, 2003, were as follows: CLASS A CLASS B CLASS C CLASS 529B CLASS 529C $7,668 $203,723 $7,180 $-- $-- - -------------------------------------------------------------------------------- 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.

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. Our procedures included confirmation of securities owned at August 31, 2003, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of MFS Research International Fund at August 31, 2003, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the periods indicated therein, in conformity with accounting principles generally accepted in the United States.

Shames] Our firm was built on the philosophy that bottom-up fundamental research is the best means of achieving superior long-term investment performance. When you're managing billions of dollars for investors, we think you have an obligation to have in-depth, firsthand knowledge of every company owned, anywhere in the world. We have structured our equity and fixed-income investment teams to capitalize on the strength of our investment process and the global reach of our analysts based around the world. Our global research team is composed of 45 equity research analysts, 27 based in the United States and 18 based abroad, and 26 credit research analysts. Each analyst is assigned one or more specific industries and then charged with identifying the most attractive investment ideas within these industries. Our U.S. and non-U.S. equity research analysts are unified into one team that emphasizes a collaborative process in analyzing securities around the globe. Credit analysts also share their expertise in each segment of the fixed-income market and work as part of the same team ensuring that every member has access to information that may have a material effect on their investment decisions. As MFS(R) continues to grow and as markets become more complex, we believe our structure will enable us to maintain a consistent investment process with the goal of providing strong, long-term investment performance across market capitalizations, investment disciplines, and country borders for our investors. THINKING GLOBALLY More companies than ever compete globally and, therefore, we must make investment decisions knowing what is occurring outside of a company's local market. This trend plays to the strength of our environment of collaboration between our analysts and portfolio managers around the globe. The analysts know the most details about individual companies in specific industries and geographic regions. The portfolio managers have broader, cross-industry insights and a wider perspective on companies and industries. Our goal is to make sure those two sets of perspectives coordinate and work well together. As the world's markets become more interdependent, we believe our collaborative environment allows us to produce solid investment ideas for our portfolios. BUILDING A NETWORK Simply put, we believe our structure assures that our analysts maintain their peripheral vision rather than becoming too immersed in a specific segment of the market. We do not believe that analysts and portfolio managers - no matter how talented they may be - can succeed by working in a vacuum. Through the latest technology available, our entire research team meets frequently via video and telephone teleconferences, e-mail, and PDAs (personal digital assistants). When we hire new analysts, we require them to spend an average of one year in Boston to learn MFS' culture and to build relationships with their peers. We believe the interaction among our analysts is the key to making our collaborative process work toward delivering superior long-term investment performance for our investors. Our analysts work out of four research offices in Boston, London, Singapore, and Tokyo, and are assigned to specific regions and industries. They meet regularly with their colleagues to discuss world trends affecting the companies they cover. In addition, our equity and fixed-income analysts often visit company managements as a team. This collaboration is vital because of the different perspectives they bring to their analysis. Because a company's stock price has tended to follow its earnings over time, our equity research analysts tend to focus on gauging earnings potential, a company's position within its industry, and its ability to grow its market share. Conversely, our fixed-income analysts will look at stability of a company's cash flow, the value of its assets, and its capital structure to gauge whether the company can generate enough free cash flow to pay off its debt. As a result of their collaboration, we believe we're able to see a more complete view of a company. WORKING TOGETHER Our portfolio managers also work closely with the analysts to select the most appropriate securities for their portfolios from the various recommendations made by the analysts. Opinions are exchanged and ideas are challenged so that each member of our team is involved in our investment process. In fact, our portfolio managers will be the first ones to tell you that many of their best ideas start with the research analysts. We believe our collaborative approach also provides us with an effective way to assess risk. Our portfolio managers are not discouraged from taking on an appropriate level of risk; however, we have rigorous guidelines to assure that the level of risk is measured and monitored and consistent with the investment philosophies of each of our portfolios. All told, we believe our culture empowers the members of our investment team to continue to do their best work and allows them to make better investment decisions. As always, we appreciate your confidence in MFS and welcome any questions or comments you may have. Respectfully, /s/ Jeffrey L. Shames Jeffrey L. Shames Chairman MFS Investment Management(R) September 15, 2003 The opinions expressed in this letter are those of MFS and no forecasts can be guaranteed. - -------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - -------------------------------------------------------------------------------- THE HUMAN SIDE OF MONEY MANAGEMENT For nearly 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 12-month period ended August 31, 2003 proved extremely volatile but rewarding for patient, long-term investors. Nearly all asset classes showed positive performance for the period, and a second-quarter 2003 rally gave investors in U.S. stocks their best quarter in many years. In retrospect, the stock market appears to us to have bottomed in the September 2002 to March 2003 time frame, driven down largely by a weak economy, corporate scandals, and geopolitical uncertainty over Iraq and North Korea. As major fighting ended in Iraq and investors became more confident in the market, we believe there was an important shift in investor sentiment. There appeared to be a return to a more rational view of stock values, one that stood in stark contrast to the exuberance that dominated the market from about 1998 to 2000 and the fear that seemed the primary motivation for investors for the next three years. It appears to us that, toward the end of the period, the market was being driven more by company fundamentals - basic business factors such as earnings and cash flow growth - than we have seen in some time. CONTRIBUTORS TO PERFORMANCE While the fund somewhat underperformed the Russell 1000 Growth Index, most share classes outperformed the fund's Lipper large-cap growth peers over the period. Consumer staples, health care, and financial services were the portfolio's strongest sectors, relative to its benchmark. A significant underweighting in the consumer staples sector helped performance as the market favored stocks in other sectors seen as less defensive areas. Especially during the second-quarter 2003 market rally, the fund benefited from not owning familiar names such as Coca-Cola and Kimberly-Clark - stocks that we felt did not fit our focused growth strategy and that, in fact, underperformed over the period. Meanwhile, our position in Avon performed well as the company's sales leadership and supply chain initiatives, boosted both revenue and earnings growth. - ----------------------------------------------- TOP 5 STOCK HOLDINGS AS OF 8/31/03 MICROSOFT CORP. 4.4% Computer software and systems company - ----------------------------------------------- CISCO SYSTEMS, INC. 3.7% Computer networking firm - ----------------------------------------------- WAL-MART STORES, INC. 2.8% General merchandise retailer - ----------------------------------------------- PFIZER, INC. 2.8% Pharmaceutical products company - ----------------------------------------------- AMGEN, INC. 2.6% Biotechnology firm - ----------------------------------------------- The portfolio is actively managed, and current holdings may be different. - ----------------------------------------------- In health care, results were helped by our holding in Forest Laboratories, a pharmaceutical firm whose products include Lexapro and Celexa for the treatment of depression. Our emphasis on biotechnology concerns also boosted returns. For example, Genentech shares climbed dramatically following the release of favorable test results for the company's colon cancer product, Avastin. This compound may be the first of a new generation of medications designed to combat cancer by cutting off blood supply to tumors. Genzyme, another biotech firm, successfully addressed an excess inventory issue involving its key drug, Renagel. In addition, the company won FDA approval for two drugs in its development pipeline. Amgen was another strong contributor in the biotech area. In the financial services sector, the portfolio's focus on capital-markets- sensitive franchises such as Citigroup and Merrill Lynch helped performance as bond spreads narrowed, trading volumes rose, and security underwriting activity showed signs of renewed life. In addition, a cash settlement from a class-action lawsuit aided performance over the period. The fund was a participant in a suit against Cendant related to alleged accounting fraud that was uncovered in 1998, after Cendant was formed by the merger of HFS and CUC International. The fund had owned both HFS and CUC, and then Cendant, during the merger period. Along with other participants in the lawsuit, the fund had suffered losses on Cendant stock in 1998. DETRACTORS FROM PERFORMANCE In the technology sector, the fund's underweighted position among electronics makers generally, and Intel specifically, was a key factor constraining relative performance. Worries that weak corporate technology spending and excess capacity would dampen profits abated during the period, as inventories contracted and certain product markets, such as laptop PCs, showed surprising strength. More generally, the fund was positioned rather conservatively across the technology sector. We maintained a slight underweighting in the sector, and favored high quality, established leaders such as IBM, Cisco, and Dell. While these stocks rose over the period, their rebound was modest when compared with that of a number of smaller capitalization companies. Strong performance of our positions in storage software leader VERITAS Software and chip maker Analog Devices, unfortunately, proved an insufficient offset for this sector. In the business services arena, a number of holdings failed to meet our expectations over the period. Automatic Data Processing (ADP), for example, had previously dealt with a weak environment - soft demand for its payroll and financial services trade processing services - by cutting costs. In March of 2003, however, ADP management signaled that they would add back some incremental expenses and take some other actions that we felt could dampen future earnings growth potential. The stock fell on the news of the change in strategy, and we sold our position. Our holdings in travel reservations firm Sabre Holdings, which we sold, and financial services transaction processor BISYS Group also declined in price over the period. Significant individual stocks that detracted from results included hospital firm Tenet Healthcare and defense contractor Northrop Grumman. Tenet shares fell on news that the firm had increased revenues by using a loophole in Medicare regulations; we sold our Tenet position over the period. Northrop Grumman disappointed investors as a number of one-time charges masked otherwise good operating performance. Respectfully, /s/ Margaret W. Adams /s/ S. Irfan Ali Margaret W. Adams S.

INDEX DEFINITIONS RUSSELL 1000 GROWTH INDEX - The Russell 1000 Growth index measures the performance of large-cap U.S. growth stocks. RUSSELL 3000 GROWTH INDEX - The Russell 3000 Growth Index measures the performance of 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. 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. All performance results reflect any applicable expense subsidies and waivers in effect during the periods shown; without these, the results would have been less favorable. See the prospectus and financial statements for details. All results are historical and assume the reinvestment of dividends and capital gains. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS, AND THE PERFORMANCE SHOWN DOES NOT REFLECT THE DEDUCTION OF TAXES, IF ANY, THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND SHARES. MARKET VOLATILITY CAN SIGNIFICANTLY AFFECT SHORT-TERM PERFORMANCE, AND MORE RECENT RETURNS MAY BE DIFFERENT FROM THOSE SHOWN. VISIT WWW.MFS.COM FOR MORE CURRENT PERFORMANCE RESULTS. 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.

See notes to financial statements. - ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS - ------------------------------------------------------------------------------- (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 - Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price 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. If no sales are reported, as is the case for most securities traded over the counter, securities are valued on the basis of quotations obtained from brokers and dealers or on the basis of valuations furnished by a pricing service. Short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes fair value as determined by the Board of Trustees. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. Portfolio investments for which market quotations are not readily available, or whose values have been materially affected by events occurring after the close of their primary markets, are valued at fair value as determined in good faith by or at the direction of the Board of Trustees. 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 - Investment valuations, other assets, and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. 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. Cash collateral is invested in short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the 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 period, the fund's fees were reduced by $3,468 under this arrangement. The fund has entered into a directed brokerage agreement, under which the broker will credit the fund a portion of the commissions generated, to offset certain expenses of the fund. For the period, the fund's other expenses were reduced by $5,061 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 fund paid no distributions for the years ended August 31, 2003 and August 31, 2002. During the year ended August 31, 2003, accumulated net investment loss decreased by $1,555,158, accumulated net realized loss on investments and foreign currency transactions decreased by $65 and paid-in capital decreased by $1,555,223 due to differences between book and tax accounting for currency transactions. This change had no effect on the net assets or net asset value per share. 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) ------------------------------------------------------------ Unrealized appreciation 31,140,549 ------------------------------------------------------------ Post-October capital loss deferral (2,744,828) ------------------------------------------------------------ Other temporary differences (104,627) ------------------------------------------------------------ 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. EXPIRATION DATE August 31, 2009 $(18,916,162) ----------------------------------------------------------- August 31, 2010 (209,919,760) ----------------------------------------------------------- August 31, 2011 (79,237,406) ----------------------------------------------------------- Total $(308,073,328) ----------------------------------------------------------- Post-October capital loss deferrals represent losses realized during the current fiscal year, but recognized for tax purposes in the next fiscal 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 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 $2.5 billion of average net assets 0.75% --------------------------------------------------------- Average net assets in excess of $2.5 billion 0.70% --------------------------------------------------------- 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). On January 1, 2002, the Trustees terminated the Independent Trustee unfunded defined benefit plan for active Trustees and converted it to an unfunded retirement benefit deferral plan for active Trustees. Under the new plan, the unfunded pension liability was converted into an equivalent value of notional shares of the fund that will fluctuate with the performance of the fund. Included in Trustees' compensation is a net decrease of $8,957 as a result of the change in the fund's pension liability under this plan and a pension expense of $4,969 for inactive trustees for the year ended August 31, 2003. 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 at the following annual percentages 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 $10,258 for the year ended August 31, 2003 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 year ended August 31, 2003 amounted to: CLASS A CLASS B CLASS C Service Fee Retained by MFD $14,579 $1,712 $7 - ------------------------------------------------------------------------------- Fees incurred under the distribution plan during the year ended August 31, 2003 were as follows: CLASS A CLASS B CLASS C Total Distribution Plan 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 year ended August 31, 2003 were as follows: CLASS A CLASS B CLASS C Contingent Deferred Sales Charges Imposed $906 $84,311 $287 - ------------------------------------------------------------------------------ SHAREHOLDER SERVICING AGENT - MFSC, a wholly owned subsidiary of MFS, earns a fee 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%. Prior to April 1, 2003, the fee was 0.10% of the fund's average daily net assets. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $156,082,715 and $184,415,625, respectively.

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. 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 year ended August 31, 2003 was $1,494. The fund had no borrowings during the year. - ------------------------------------------------------------------------------- INDEPENDENT AUDITORS - ------------------------------------------------------------------------------- To the Trustees of MFS Series Trust I and the Shareholders of MFS Managed Sectors Fund: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of MFS Managed Sectors Fund (one of the series comprising MFS Series Trust I) (the "Trust") as of August 31, 2003, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of August 31, 2003, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such financial statements present fairly, in all material respects, the financial position of MFS Managed Sectors Fund as of August 31, 2003, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Shames] Our firm was built on the philosophy that bottom-up fundamental research is the best means of achieving superior long-term investment performance. When you're managing billions of dollars for investors, we think you have an obligation to have in-depth, firsthand knowledge of every company owned, anywhere in the world. We have structured our equity and fixed-income investment teams to capitalize on the strength of our investment process and the global reach of our analysts based around the world. Our global research team is composed of 45 equity research analysts, 27 based in the United States and 18 based abroad, and 26 credit research analysts. Each analyst is assigned one or more specific industries and then charged with identifying the most attractive investment ideas within these industries. Our U.S. and non-U.S. equity research analysts are unified into one team that emphasizes a collaborative process in analyzing securities around the globe. Credit analysts also share their expertise in each segment of the fixed-income market and work as part of the same team ensuring that every member has access to information that may have a material effect on their investment decisions. As MFS(R) continues to grow and as markets become more complex, we believe our structure will enable us to maintain a consistent investment process with the goal of providing strong, long-term investment performance across market capitalizations, investment disciplines, and country borders for our investors. THINKING GLOBALLY More companies than ever compete globally and, therefore, we must make investment decisions knowing what is occurring outside of a company's local market. This trend plays to the strength of our environment of collaboration between our analysts and portfolio managers around the globe. The analysts know the most details about individual companies in specific industries and geographic regions. The portfolio managers have broader, cross-industry insights and a wider perspective on companies and industries. Our goal is to make sure those two sets of perspectives coordinate and work well together. As the world's markets become more interdependent, we believe our collaborative environment allows us to produce solid investment ideas for our portfolios. BUILDING A NETWORK Simply put, we believe our structure assures that our analysts maintain their peripheral vision rather than becoming too immersed in a specific segment of the market. We do not believe that analysts and portfolio managers - no matter how talented they may be - can succeed by working in a vacuum. Through the latest technology available, our entire research team meets frequently via video and telephone teleconferences, e-mail, and PDAs (personal digital assistants). When we hire new analysts, we require them to spend an average of one year in Boston to learn MFS' culture and to build relationships with their peers. We believe the interaction among our analysts is the key to making our collaborative process work toward delivering superior long-term investment performance for our investors. Our analysts work out of four research offices in Boston, London, Singapore, and Tokyo, and are assigned to specific regions and industries. They meet regularly with their colleagues to discuss world trends affecting the companies they cover. In addition, our equity and fixed-income analysts often visit company managements as a team. This collaboration is vital because of the different perspectives they bring to their analysis. Because a company's stock price has tended to follow its earnings over time, our equity research analysts tend to focus on gauging earnings potential, a company's position within its industry, and its ability to grow its market share. Conversely, our fixed-income analysts will look at stability of a company's cash flow, the value of its assets, and its capital structure to gauge whether the company can generate enough free cash flow to pay off its debt. As a result of their collaboration, we believe we're able to see a more complete view of a company. WORKING TOGETHER Our portfolio managers also work closely with the analysts to select the most appropriate securities for their portfolios from the various recommendations made by the analysts. Opinions are exchanged and ideas are challenged so that each member of our team is involved in our investment process. In fact, our portfolio managers will be the first ones to tell you that many of their best ideas start with the research analysts. We believe our collaborative approach also provides us with an effective way to assess risk. Our portfolio managers are not discouraged from taking on an appropriate level of risk; however, we have rigorous guidelines to assure that the level of risk is measured and monitored and consistent with the investment philosophies of each of our portfolios. All told, we believe our culture empowers the members of our investment team to continue to do their best work and allows them to make better investment decisions. As always, we appreciate your confidence in MFS and welcome any questions or comments you may have. Respectfully, /s/ Jeffrey L. Shames Jeffrey L. Shames Chairman MFS Investment Management(R) September 15, 2003 The opinions expressed in this letter are those of MFS and no forecasts can be guaranteed. - -------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - -------------------------------------------------------------------------------- THE HUMAN SIDE OF MONEY MANAGEMENT For nearly 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 12-month period ended August 31, 2003, proved volatile but rewarding for long-term investors. As the economy and the stock market appeared to turn a corner into recovery, small-cap growth stocks, as represented by the fund's benchmark, the Russell 2000 Growth Index, outperformed the broad market, as represented by the Standard & Poor's 500 Stock Index. The indices returned 34.90% and 12.07%, respectively. In retrospect, the stock market appears to have bottomed in the September 2002 to March 2003 time frame, driven down largely by a weak economy, corporate scandals, and geopolitical uncertainty over Iraq and North Korea. As major fighting ended in Iraq and investors became more confident in the market, stocks began to rise - both in anticipation of an accelerating economic recovery and in response to real improvements in business fundamentals (such as earnings and cash flow growth). Beginning in late 2002, we had begun to restructure the portfolio. We felt that, as the economy strengthened further, corporate capital expenditure (cap- ex) spending would increase and the market would increasingly favor companies that stood to benefit from increased cap-ex spending - such as firms in the technology and industrial goods and services sectors. We also felt that growth in consumer spending, which had largely driven the U.S. economy for the past three years, could taper off somewhat. Accordingly, we decreased the fund's exposure to retail and consumer staples stocks over the period, and increased our technology holdings. - ------------------------------------------------- TOP 5 STOCK HOLDINGS AS OF 8/31/03 CAREMARK RX, INC. 2.5% Pharmaceutical benefits management firm - ------------------------------------------------- CAREER EDUCATION CORP. 1.7% For-profit provider of post-secondary education - ------------------------------------------------- KRONOS, INC. 1.5% Provider of software-based employee management systems - ------------------------------------------------- STRAYER EDUCATION, INC. 1.4% For-profit provider of post-secondary education - ------------------------------------------------- OPEN TEXT CORP. 1.3% Developer of knowledge management software - ------------------------------------------------- The portfolio is actively managed, and current holdings may be different. - ------------------------------------------------- DETRACTORS FROM PERFORMANCE We think the fund's underperformance over the period, relative to its Russell 2000 Growth benchmark and its Lipper small-cap growth peers, can be attributed in part to the character of the second-quarter 2003 rally. In general, we felt some of the better-performing stocks over the period were higher-volatility, more risky issues. Many were stocks that had fallen to extremely low prices before the market appeared to bottom and then delivered strong performance off of that bottom. Most of those stocks did not fit the fund's strategy of investing in firms that we feel have strong long-term business fundamentals. While sticking with our strategy hurt performance over the period, we believe that avoiding stocks with relatively weak fundamentals helps our shareholders over the longer term. More specifically, we were late in participating in a powerful second-quarter rally in the technology sector. We generally do not like to invest in a company until we have confidence that its fundamentals are likely to improve, and many of the technology firms that led the rally were companies in which we had no long-term confidence. However, while our technology holdings as a group underperformed on a relative basis, many delivered strong results over the period; in fact, three of the fund's five top performing holdings were in the sector. Lexar Media's stock rose sharply on strong demand for the firm's removable storage media for digital cameras. GlobespanVirata increased its share of the market for semiconductor chips used in DSL (digital subscriber line) broadband internet systems. The position in GlobespanVirata has since been eliminated from the portfolio. And Avid Technology continued to be a market leader in digital editing equipment for the film and broadcasting industries. Leisure sector holdings also detracted from performance. Despite the success of its Harry Potter franchise, Scholastic Corp.'s stock tumbled because the weak economy hurt sales of children's books, especially at school book fairs. Our stake in Jack in the Box declined in value as the fast food restaurant firm's turnaround efforts proved disappointing. We sold both holdings by period-end. Elsewhere in the sector, our radio broadcasting stocks underperformed because local radio advertising did not recover as quickly as expected after major fighting concluded in Iraq. Health care was another area that held back performance. Much of the market's strong performance in the sector came from rather speculative biotechnology stocks, and we were underweighted in that industry. In addition, our holdings in LifePoint Hospitals, a group of rural hospitals, and AMN Healthcare, a provider of temporary nursing services, declined in price and were sold out of the fund. CONTRIBUTORS TO PERFORMANCE In the financial services sector, relative performance was helped by a general avoidance of several areas that performed poorly, particularly banks, whose profits were hurt by low interest rates, and insurance brokers. In addition, we owned a few selected banks that did well because they were in high-growth markets, such as California-based UCBH Holdings, which focused on Chinese-American clients and began expanding into New York. We also owned some brokerage firms that profited from increased market activity. Chief among the latter was Friedman Billings Ramsey, an investment banking and brokerage firm. In the consumer staples area, the fund benefited from a lower allocation to the sector, as the market rotated away from defensive stocks and began to favor more aggressive issues. Similarly, the fund's outperformance in the basic materials sector was largely due to low allocation to a sector that underperformed. The fund's strongest performing holdings over the period were spread across a variety of sectors. In addition to the technology companies mentioned earlier, contributors to performance included adult education firms Career Education and Strayer Education. These companies saw increasing enrollment rates and benefited from the weak employment environment in the United States, as they offered workers opportunities to increase job-related knowledge and skills. In the health care area, our long-time holding in pharmaceutical benefits manager Caremark Rx performed well. The firm manages prescription drug benefits for employers in order to hold down the cost of health insurance. And in the leisure sector, stock in educational toy company Leapfrog Enterprises rose on the success of a new product line. Respectfully, /s/ Robert A. Henderson /s/ Donald F. Pitcher, Jr. Robert A.

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 R 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. All performance results reflect any applicable expense subsidies and waivers in effect during the periods shown; without these, the results would have been less favorable. See the prospectus and financial statements for details. All results are historical and assume the reinvestment of dividends and capital gains. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS, AND THE PERFORMANCE SHOWN DOES NOT REFLECT THE DEDUCTION OF TAXES, IF ANY, THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND SHARES. MARKET VOLATILITY CAN SIGNIFICANTLY AFFECT SHORT-TERM PERFORMANCE, AND MORE RECENT RETURNS MAY BE DIFFERENT FROM THOSE SHOWN. VISIT WWW.MFS.COM FOR MORE CURRENT PERFORMANCE RESULTS. 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 - 8/31/03 - ------------------------------------------------------------------------------------------------------- The Portfolio of Investments is a complete list of all securities owned by your fund.

See notes to financial statements. - ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS - ------------------------------------------------------------------------------- (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 - Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price 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. If no sales are reported, as is the case for most securities traded over the counter, securities are valued on the basis of quotations obtained from brokers and dealers or on the basis of valuations furnished by a pricing service. Short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes fair value as determined by the Board of Trustees. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. Portfolio investments for which market quotations are not readily available, or whose values have been materially affected by events occurring after the close of their primary markets, are valued at fair value as determined in good faith by or at the direction of the Board of Trustees. 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 - Investment valuations, other assets, and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. 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. Cash collateral is invested in short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the 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. At August 31, 2003, the value of securities loaned was $304,358,282. These loans were collateralized by cash of $311,871,571 and non cash U.S. Treasury obligations of $475,953. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. All premium and discount is amortized or accreted for financial statement purposes in accordance with generally accepted accounting principles. 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 period, the fund's custodian fees were reduced by $20,381 under this arrangement. The fund has entered into a directed brokerage agreement, under which the broker will credit the fund a portion of the commissions generated, to offset certain expenses of the fund. For the period, the fund's other expenses were reduced by $18,840 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, real estate investment trusts, wash sales 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 $-- $23,344 - -------------------------------------------------------------------------------- During the year ended August 31, 2003, accumulated net investment loss decreased by $14,400,855, accumulated net realized loss on investments and foreign currency transactions increased by $3,818, and paid-in capital decreased by $14,397,037 due to differences between book and tax accounting for currency transactions and net operating losses. This change had no effect on the net assets or net asset value per share. 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) - -------------------------------------------------------------------------------- Unrealized appreciation 257,619,886 - -------------------------------------------------------------------------------- Post October capital loss deferral (4,559,698) - -------------------------------------------------------------------------------- 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 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). On January 1, 2002, the Trustees terminated the Independent Trustee unfunded defined benefit plan for active Trustees. Included in Trustees' compensation is a pension expense of $1,555 for inactive trustees for the year ended August 31, 2003. 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 at the following annual percentages 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 $74,527 and $510 for the year ended August 31, 2003, 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 R, 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 R CLASS 529A CLASS 529B CLASS 529C Distribution Fee 0.10% 0.75% 0.75% 0.25% 0.25% 0.75% 0.75% - -------------------------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% 0.25% 0.25% 0.25% 0.25% - -------------------------------------------------------------------------------------------------- Total Distribution Plan 0.35% 1.00% 1.00% 0.50% 0.50% 1.00% 1.00% - -------------------------------------------------------------------------------------------------- MFD retains the service fee for accounts not attributable to a securities dealer, which for the year ended August 31, 2003, amounted to: CLASS A CLASS B CLASS C CLASS R CLASS 529A CLASS 529B CLASS 529C Service Fee Retained by MFD $34,390 $2,223 $1,229 $-- $51 $-- $-- - -------------------------------------------------------------------------------------------------- CLASS A CLASS B CLASS C CLASS R CLASS 529A CLASS 529B CLASS 529C Total Distribution Plan 0.35% 1.00% 1.00% 0.50% 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 date as the Trustees of the trust may determine. Fees incurred under the distribution plan during the year ended August 31, 2003, were as follows: 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 year ended August 31, 2003, were as follows: CLASS A CLASS B CLASS 529B CLASS C CLASS 529C Contingent Deferred Sales Charges Imposed $10,842 $425,879 $-- $8,629 $-- - -------------------------------------------------------------------------------- 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 0.25% 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.

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. Our procedures included confirmation of securities owned at August 31, 2003, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of MFS New Discovery Fund at August 31, 2003, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the periods indicated therein, in conformity with accounting principles generally accepted in the United States.

Shames] Our firm was built on the philosophy that bottom-up fundamental research is the best means of achieving superior long-term investment performance. When you're managing billions of dollars for investors, we think you have an obligation to have in-depth, firsthand knowledge of every company owned, anywhere in the world. We have structured our equity and fixed-income investment teams to capitalize on the strength of our investment process and the global reach of our analysts based around the world. Our global research team is composed of 45 equity research analysts, 27 based in the United States and 18 based abroad, and 26 credit research analysts. Each analyst is assigned one or more specific industries and then charged with identifying the most attractive investment ideas within these industries. Our U.S. and non-U.S. equity research analysts are unified into one team that emphasizes a collaborative process in analyzing securities around the globe. Credit analysts also share their expertise in each segment of the fixed-income market and work as part of the same team ensuring that every member has access to information that may have a material effect on their investment decisions. As MFS(R) continues to grow and as markets become more complex, we believe our structure will enable us to maintain a consistent investment process with the goal of providing strong, long-term investment performance across market capitalizations, investment disciplines, and country borders for our investors. THINKING GLOBALLY More companies than ever compete globally and, therefore, we must make investment decisions knowing what is occurring outside of a company's local market. This trend plays to the strength of our environment of collaboration between our analysts and portfolio managers around the globe. The analysts know the most details about individual companies in specific industries and geographic regions. The portfolio managers have broader, cross-industry insights and a wider perspective on companies and industries. Our goal is to make sure those two sets of perspectives coordinate and work well together. As the world's markets become more interdependent, we believe our collaborative environment allows us to produce solid investment ideas for our portfolios. BUILDING A NETWORK Simply put, we believe our structure assures that our analysts maintain their peripheral vision rather than becoming too immersed in a specific segment of the market. We do not believe that analysts and portfolio managers - no matter how talented they may be - can succeed by working in a vacuum. Through the latest technology available, our entire research team meets frequently via video and telephone teleconferences, e-mail, and PDAs (personal digital assistants). When we hire new analysts, we require them to spend an average of one year in Boston to learn MFS' culture and to build relationships with their peers. We believe the interaction among our analysts is the key to making our collaborative process work toward delivering superior long-term investment performance for our investors. Our analysts work out of four research offices in Boston, London, Singapore, and Tokyo, and are assigned to specific regions and industries. They meet regularly with their colleagues to discuss world trends affecting the companies they cover. In addition, our equity and fixed-income analysts often visit company managements as a team. This collaboration is vital because of the different perspectives they bring to their analysis. Because a company's stock price has tended to follow its earnings over time, our equity research analysts tend to focus on gauging earnings potential, a company's position within its industry, and its ability to grow its market share. Conversely, our fixed-income analysts will look at stability of a company's cash flow, the value of its assets, and its capital structure to gauge whether the company can generate enough free cash flow to pay off its debt. As a result of their collaboration, we believe we're able to see a more complete view of a company. WORKING TOGETHER Our portfolio managers also work closely with the analysts to select the most appropriate securities for their portfolios from the various recommendations made by the analysts. Opinions are exchanged and ideas are challenged so that each member of our team is involved in our investment process. In fact, our portfolio managers will be the first ones to tell you that many of their best ideas start with the research analysts. We believe our collaborative approach also provides us with an effective way to assess risk. Our portfolio managers are not discouraged from taking on an appropriate level of risk; however, we have rigorous guidelines to assure that the level of risk is measured and monitored and consistent with the investment philosophies of each of our portfolios. All told, we believe our culture empowers the members of our investment team to continue to do their best work and allows them to make better investment decisions. As always, we appreciate your confidence in MFS and welcome any questions or comments you may have. Respectfully, /s/ Jeffrey L. Shames Jeffrey L. Shames Chairman MFS Investment Management(R) September 15, 2003 The opinions expressed in this letter are those of MFS and no forecasts can be guaranteed. - ------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - ------------------------------------------------------------------------------- THE HUMAN SIDE OF MONEY MANAGEMENT For nearly 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 - ------------------------------------------------------------------------------- A RALLY, A RETREAT, AND ANOTHER RALLY Modest economic improvements and slightly stronger corporate earnings sparked a stock market rally in October and November 2002 that was led by technology stocks. The stock markets cooled in the winter months of 2003 because of mixed economic signals and an increase in geopolitical tensions. However, the market began to rebound in mid-March and continued almost without pause for the balance of the reporting period. Once more, technology stocks led the way. PORTFOLIO POSITIONING At the start of the period, we positioned the fund conservatively in larger, high-quality companies that we believed had solid cash balances and established franchises. Although these stocks participated in the October/ November rally, they underperformed many of the higher risk companies. The historically more volatile stocks led the 2003 rally as well and turned in stronger results than their more conservative counterparts. Larger companies, as measured by market capitalization, generated lower returns than smaller, aggressively managed firms. Throughout the latter half of the period, the fund was a little less conservative in its stock selections and was underweighted in large-cap names such as IBM and Microsoft. That shift in positioning helped both absolute and relative returns. DETRACTORS FROM PERFORMANCE Although the fund's absolute returns were strong for the reporting period, its relative returns were lower than its benchmark. The fund's underweighting in Intel relative to its benchmark was one of the largest detractors from performance. On average, Intel represented slightly more than 4% of the fund's portfolio during the period and was one of the fund's largest positions in the second half of the period. The company contributed solid returns to absolute performance. However, Intel averaged nearly 9.25% of the Goldman Sachs Technology Index and, as a result of that heavier weighting, Intel made a greater contribution to the index's return. We generally do not hold that large a position in any single stock, particularly in an uncertain market environment. We did not invest heavily in Internet services company Yahoo! because, in part, we thought that its stock price was too high in comparison to its potential future earnings. As a result, we did not participate fully in the appreciation of the Yahoo! stock. Other stocks that held back performance included Sega, Motorola, Qualcomm, Bisys, and Sabre. Videogame maker Sega disappointed investors in late 2002 when it failed to sell as much game software as many had expected. The company lost some of its market share to key competitors Sony and Nintendo. In the first and second quarters of 2003, cell phone manufacturers Motorola and Qualcomm experienced sliding sales in their large Asian markets because of severe acute respiratory syndrome (SARS) and increased competition. Cell phone sales for both companies improved during the summer. The stock prices of business services companies Bisys and Sabre are sensitive to changes in the economic environment. Bisys provides distribution services for financial services firms. The company did not meet its revenue expectations for its education and insurance divisions. Sabre, an airline reservation services company, saw its fee-based income decline because of weakness in the travel industry. The fund no longer owns this stock. CONTRIBUTORS TO PERFORMANCE The fund's analysts generally made strong choices in the electronics and the PC & peripherals industries. In electronics, Marvell Technology Group delivered outstanding results for the fund. The company is a semiconductor provider of broadband communications chips and data storage chips. Its Gigabit Ethernet products replace current industry-standard 100-megabit products with chips that provide faster access to the Internet, other computers, and software applications. The company experienced a growing market share in a segment of the industry that is rapidly expanding. In the PC & peripherals industry, Avid Technology contributed strong returns to fund performance. The company makes digital animation and film editing hardware and software for broadcasters and filmmakers. Avid's sales to broadcasters picked up significantly because the Federal Communications Commission is requiring broadcasters to upgrade to high definition TV (which is a digital signal). In 2003, 50% of all programming is required to be HDTV, 75% in 2005, and 100% in 2006. As a result, broadcasters have to upgrade to digital editing equipment, such as that made by Avid, so that programs can be properly mastered. Stock selections in computer software were another strong group for the period. Amdocs makes software products and services used to manage wireless customer billing. As communications companies offer more wireless services such as Internet access, personal messaging, and family calling plans, billing becomes more complex. Amdocs software helps major communications companies bill accurately for services used. The company's stock price rose steadily throughout the period and was given an added lift by the general technology rally. Symantec, a content and network security software maker, which has since been sold out of the portfolio and Citrix, an application management software maker, also contributed to fund 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 R 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. All performance results reflect any applicable expense subsidies and waivers in effect during the periods shown; without these, the results would have been less favorable. See the prospectus and financial statements for details. All results are historical and assume the reinvestment of dividends and capital gains. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS, AND THE PERFORMANCE SHOWN DOES NOT REFLECT THE DEDUCTION OF TAXES, IF ANY, THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND SHARES. MARKET VOLATILITY CAN SIGNIFICANTLY AFFECT SHORT-TERM PERFORMANCE, AND MORE RECENT RETURNS MAY BE DIFFERENT FROM THOSE SHOWN. VISIT WWW.MFS.COM FOR MORE CURRENT PERFORMANCE RESULTS. 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 - 8/31/03 - ----------------------------------------------------------------------------------------------------- The Portfolio of Investments is a complete list of all securities owned by your fund.

See notes to financial statements. - ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS - ------------------------------------------------------------------------------- (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 - Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price 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. If no sales are reported, as is the case for most securities traded over the counter, securities are valued on the basis of quotations obtained from brokers and dealers or on the basis of valuations furnished by a pricing service. Short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes fair value as determined by the Board of Trustees. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. Portfolio investments for which market quotations are not readily available, or whose values have been materially affected by events occurring after the close of their primary markets, are valued at fair value as determined in good faith by or at the direction of the Board of Trustees. 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 - Investment valuations, other assets, and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. 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. Cash collateral is invested in short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the 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 generally accepted accounting principles. 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 period, the fund's custodian fees were reduced by $1,124 under this arrangement. The fund has entered into a directed brokerage agreement, under which the broker will credit the fund a portion of the commissions generated, to offset certain expenses of the fund. For the period, the fund's other expenses were reduced by $23,776 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. During the year ended August 31, 2003, accumulated net investment loss decreased by $1,360,190, accumulated net realized loss on investments and foreign currency transactions decreased by $4,707, and paid-in capital decreased by $1,364,897 due to differences between book and tax accounting for currency transactions and net operating losses. This change had no effect on the net assets or net asset value per share. 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) ------------------------------------------------------------------ Unrealized appreciation 26,018,772 ------------------------------------------------------------------ Post-October capital loss deferral (17,293,212) ------------------------------------------------------------------ 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. The fund has a temporary expense reimbursement agreement whereby MFS has contractually agreed to pay all of the fund's operating expenses, exclusive of management, distribution, and service fees. The fund in turn will pay 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 R. To the extent that the expense reimbursement fee exceeds the fund's actual expenses, the excess will be applied to amounts paid by MFS in prior years. At August 31, 2003, aggregate unreimbursed expenses amounted to $158,361. The reimbursement plan expired on April 1, 2003. MFS instituted a new plan through 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 inactive Trustees and an unfunded retirement benefit deferral plan for active Trustees. Included in Trustees' compensation is a net increase of $36,098 as a result of the change in the fund's pension liability under this plan and a pension expense of $586 for inactive trustees for the year ended August 31, 2003. The Trustees are currently waiving their right to receive compensation from this 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 at the following annual percentages 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 $12,381 for the year ended August 31, 2003, 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 and Class R 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 R Distribution Fee 0.10% 0.75% 0.75% 0.25% - -------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% 0.25% - -------------------------------------------------------------------------------- Total Distribution Plan 0.35% 1.00% 1.00% 0.50% - -------------------------------------------------------------------------------- MFD retains the service fee for accounts not attributable to a securities dealer, which for the year ended August 31, 2003, amounted to: CLASS A CLASS B CLASS C CLASS R Service Fee Retained by MFD $20,866 $329 $31 $-- - -------------------------------------------------------------------------------- Fees incurred under the distribution plan during the year ended August 31, 2003, were as follows: CLASS A CLASS B CLASS C CLASS R Total Distribution Plan 0.35% 1.00% 1.00% 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 year ended August 31, 2003, were as follows: CLASS A CLASS B CLASS C CLASS R Contingent Deferred Sales Charges Imposed $741 $69,979 $3,442 $-- - -------------------------------------------------------------------------------- SHAREHOLDER SERVICING AGENT - MFSC, a wholly owned subsidiary of MFS, earns a fee 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%. Prior to April 1, 2003, the fee was 0.10% of the fund's average daily net assets. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $182,698,766 and $170,698,048, 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 $186,694,349 ------------------------------------------------------------------ Gross unrealized appreciation $27,719,520 ------------------------------------------------------------------ Gross unrealized depreciation (1,698,192) ------------------------------------------------------------------ Net unrealized appreciation $26,021,328 ------------------------------------------------------------------ (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. 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 year ended August 31, 2003, was $638. The fund had no significant borrowings during the year. (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 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 Telecommunication 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. - ------------------------------------------------------------------------------- INDEPENDENT AUDITORS' REPORT - ------------------------------------------------------------------------------- To the Trustees of MFS Series Trust I and Shareholders of MFS Technology Fund: We have audited the accompanying statement of assets and liabilities of MFS Technology Fund (the Fund) (one of the portfolios constituting MFS Series Trust I), including the portfolio of investments, as of August 31, 2003, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. Our procedures included confirmation of securities owned at August 31, 2003, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of MFS Technology Fund at August 31, 2003, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the periods indicated therein, in conformity with accounting principles generally accepted in the United States.

Shames] Our firm was built on the philosophy that bottom-up fundamental research is the best means of achieving superior long-term investment performance. When you're managing billions of dollars for investors, we think you have an obligation to have in-depth, firsthand knowledge of every company owned, anywhere in the world. We have structured our equity and fixed-income investment teams to capitalize on the strength of our investment process and the global reach of our analysts based around the world. Our global research team is composed of 45 equity research analysts, 27 based in the United States and 18 based abroad, and 26 credit research analysts. Each analyst is assigned one or more specific industries and then charged with identifying the most attractive investment ideas within these industries. Our U.S. and non-U.S. equity research analysts are unified into one team that emphasizes a collaborative process in analyzing securities around the globe. Credit analysts also share their expertise in each segment of the fixed-income market and work as part of the same team ensuring that every member has access to information that may have a material effect on their investment decisions. As MFS(R) continues to grow and as markets become more complex, we believe our structure will enable us to maintain a consistent investment process with the goal of providing strong, long-term investment performance across market capitalizations, investment disciplines, and country borders for our investors. THINKING GLOBALLY More companies than ever compete globally and, therefore, we must make investment decisions knowing what is occurring outside of a company's local market. This trend plays to the strength of our environment of collaboration between our analysts and portfolio managers around the globe. The analysts know the most details about individual companies in specific industries and geographic regions. The portfolio managers have broader, cross-industry insights and a wider perspective on companies and industries. Our goal is to make sure those two sets of perspectives coordinate and work well together. As the world's markets become more interdependent, we believe our collaborative environment allows us to produce solid investment ideas for our portfolios. BUILDING A NETWORK Simply put, we believe our structure assures that our analysts maintain their peripheral vision rather than becoming too immersed in a specific segment of the market. We do not believe that analysts and portfolio managers - no matter how talented they may be - can succeed by working in a vacuum. Through the latest technology available, our entire research team meets frequently via video and telephone teleconferences, e-mail, and PDAs (personal digital assistants). When we hire new analysts, we require them to spend an average of one year in Boston to learn MFS' culture and to build relationships with their peers. We believe the interaction among our analysts is the key to making our collaborative process work toward delivering superior long-term investment performance for our investors. Our analysts work out of four research offices in Boston, London, Singapore, and Tokyo, and are assigned to specific regions and industries. They meet regularly with their colleagues to discuss world trends affecting the companies they cover. In addition, our equity and fixed-income analysts often visit company managements as a team. This collaboration is vital because of the different perspectives they bring to their analysis. Because a company's stock price has tended to follow its earnings over time, our equity research analysts tend to focus on gauging earnings potential, a company's position within its industry, and its ability to grow its market share. Conversely, our fixed-income analysts will look at stability of a company's cash flow, the value of its assets, and its capital structure to gauge whether the company can generate enough free cash flow to pay off its debt. As a result of their collaboration, we believe we're able to see a more complete view of a company. WORKING TOGETHER Our portfolio managers also work closely with the analysts to select the most appropriate securities for their portfolios from the various recommendations made by the analysts. Opinions are exchanged and ideas are challenged so that each member of our team is involved in our investment process. In fact, our portfolio managers will be the first ones to tell you that many of their best ideas start with the research analysts. We believe our collaborative approach also provides us with an effective way to assess risk. Our portfolio managers are not discouraged from taking on an appropriate level of risk; however, we have rigorous guidelines to assure that the level of risk is measured and monitored and consistent with the investment philosophies of each of our portfolios.

Nearly all asset classes showed positive performance for the period, and a second-quarter 2003 rally gave investors in U.S. stocks their best quarter in many years. Modest economic improvements and slightly stronger corporate earnings sparked a stock market rally in October and November 2002. The stock markets cooled in the winter months of 2003 because of mixed economic signals and an increase in geopolitical tensions. However, the market began a rebound in mid-March that continued almost without pause for the balance of the reporting period. Technology and utilities & communications were among the market's leaders during the rallies. DETRACTORS FROM PERFORMANCE Although the technology sector and the utilities and communications sector contributed strong absolute returns to fund performance, they detracted from performance relative to the fund's benchmark because we were underweighted in both areas during the October/November rally. Since then, we have brought both sector weightings in line with the benchmark. Our investments in Microsoft and Network Associates detracted from performance throughout the period, and so did our decision not to own Intel - one of the better performing stocks for the period. Microsoft posted positive results for the period but did not perform as well as some of the other technology stocks. Network Associates, a network management and security provider, missed its earnings estimates and its stock price declined. However, as of the end of the period, we continue to own the stock because we like the company's longer-term prospects and its new product flow. - ----------------------------------------------- TOP 5 STOCK HOLDINGS AS OF 8/31/03 CITIGROUP, INC. 3.9% Diversified financial services company - ----------------------------------------------- GENERAL ELECTRIC CO. 3.4% Diversified manufacturing and financial services conglomerate - ----------------------------------------------- WYETH 3.1% Pharmaceutical and health care products company - ----------------------------------------------- MICROSOFT CORP. 2.6% Computer software and systems company - ----------------------------------------------- SCHERING-PLOUGH CORP. 2.2% Pharmaceutical products company - ----------------------------------------------- The portfolio is actively managed, and current holdings may be different. - ----------------------------------------------- The utilities and communications sector, particularly the telecommunications industry, rebounded sharply during the period because of progress made in cleaning up their balance sheets. Our analysts had favored the telecom companies with stronger balance sheets, but the companies that delivered the strongest returns were companies such as Nextel and AT&T Wireless, both of which had a significant amount of debt on their books. The stock price of Verizon, a wireless and wireline communications provider, rose significantly during the period; however, we did not own the stock for a large portion of its rise. Sears Roebuck was one of our biggest disappointments for the period. The stock declined in the fall of 2002 after the company announced that the quality of its credit card portfolio was worse than the firm had previously known or disclosed. The company's stock price rose in 2003 after Sears announced that it would sell its troubled credit card business to focus more closely on restructuring its retail franchise, which helped to recoup some of the earlier losses. CONTRIBUTORS TO PERFORMANCE Biotechnology and medical products stocks, as well as financial services turned in the strongest performance for the period. In biotechnology, Genzyme and Genentech were strong contributors for the period. Investors overreacted to near-term events at Genzyme and its stock fell to excessively low levels. As sales picked up for the firm, and its developmental drugs showed promise, the price of the stock rebounded. Genentech's stock price received a lift from successful early trials of its colorectal cancer drug, Avastin. In medical technology, investors boosted the stock prices of Thoratec and Hologic in anticipation of new product releases from both companies. The price of Tenet Healthcare stock dropped sharply in 2002 when the company announced it was being investigated for its Medicare billing practices. Our analysts looked closely at the company and thought that it had very valuable assets. We bought the stock after the bad news had come out and it has since rebounded. Strong stock selection in financial services made solid contributions to fund performance for the period. MBNA, FleetBoston, and Merrill Lynch were standouts in the group. Throughout the difficult 2002 market, investment banking firm Merrill Lynch cut costs more deeply than many of the other firms that we follow. When the market rallied, the company's stock price rose higher than its competitors because of its earlier efforts. MBNA announced in early 2003 that it had to make a one-time increase to its reserves for sub-prime credit card business. (The term sub-prime refers to card holders with weak credit histories.) That increase reduced the company's revenues and its stock price declined as a result. We purchased the stock after it made the announcement because the company had also announced that it was deemphasizing this part of its business. With the improvement in the economy, and the company's further moves to reduce its exposure to sub-prime debt, investors returned to the stock, it rose back to previous levels, and the fund received a nice boost to performance. In the fall of 2002, investors became concerned about FleetBoston's loan exposure in the volatile telecommunications industry and in Latin America, particularly Brazil. However, in 2003, the telecom industry stabilized and concerns abated about Brazil when the country's new president proved to be more business friendly than many had thought. Fleet's stock price rose and that also contributed to fund performance. /s/ David A. Antonelli David A.

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 R 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. All performance results reflect any applicable expense subsidies and waivers in effect during the periods shown; without these, the results would have been less favorable. See the prospectus and financial statements for details. All results are historical and assume the reinvestment of dividends and capital gains. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS, AND THE PERFORMANCE SHOWN DOES NOT REFLECT THE DEDUCTION OF TAXES, IF ANY, THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND SHARES. MARKET VOLATILITY CAN SIGNIFICANTLY AFFECT SHORT-TERM PERFORMANCE, AND MORE RECENT RETURNS MAY BE DIFFERENT FROM THOSE SHOWN. VISIT WWW.MFS.COM FOR MORE CURRENT PERFORMANCE RESULTS.

See notes to financial statements. - ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS - ------------------------------------------------------------------------------- (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 - Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price 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. If no sales are reported, as is the case for most securities traded over the counter, securities are valued on the basis of quotations obtained from brokers and dealers or on the basis of valuations furnished by a pricing service. Short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes fair value as determined by the Board of Trustees. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. Portfolio investments for which market quotations are not readily available, or whose values have been materially affected by events occurring after the close of their primary markets, are valued at fair value as determined in good faith by or at the direction of the Board of Trustees. FOREIGN CURRENCY TRANSLATION - Investment valuations, other assets, and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. 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. Cash collateral is invested in short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the 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 discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. Some securities may be purchased on a "when-issued" or "forward delivery" basis, which means that the securities will be delivered to the fund at a future date, usually beyond customary settlement time. 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 period, the fund's custodian fees were reduced by $1,465 under this arrangement. The fund has entered into a directed brokerage agreement, under which the broker will credit the fund a portion of the commissions generated, to offset certain expenses of the fund. For the period, the fund's other expenses were reduced by $21,135 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. 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. During the year ended August 31, 2003, accumulated net investment loss decreased by $164,685, accumulated net realized loss on investments and foreign currency transactions increased by $14,603, and paid-in capital decreased by $150,082 due to differences between book and tax accounting for currency transactions and net operating losses. This change had no effect on the net assets or net asset value per share. 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 losses deferred (2,824,860) ------------------------------------------------------------------ Other temporary differences (63,317) ------------------------------------------------------------------ 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 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). On January 1, 2002, the Trustees terminated the Independent Trustee unfunded defined benefit plan for active Trustees and converted it to an unfunded retirement benefit deferral plan for active Trustees. Under the new plan, the unfunded pension liability was converted into an equivalent value of notional shares of the fund that will fluctuate with the performance of the fund. Included in Trustees' compensation is a net decrease of $5,885 as a result of the change in the fund's pension liability under this plan and a pension expense of $2,192 for inactive trustees for the year ended August 31, 2003. 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 at the following annual percentages 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 $16,035 for the year ended August 31, 2003, 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, and Class R 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 R Distribution Fee 0.10% 0.75% 0.75% 0.25% - -------------------------------------------------------------------------------- Service Fee 0.25% 0.25% 0.25% 0.25% - -------------------------------------------------------------------------------- Total Distribution Plan 0.35% 1.00% 1.00% 0.50% - -------------------------------------------------------------------------------- MFD retains the service fee for accounts not attributable to a securities dealer, which for the year ended August 31, 2003, amounted to: CLASS A CLASS B CLASS C CLASS R Service Fee Retained by MFD $1,891 $690 $527 $-- - -------------------------------------------------------------------------------- Fees incurred under the distribution plan during the year ended August 31, 2003, were as follows: CLASS A CLASS B CLASS C CLASS R Total Distribution Plan 0.35% 1.00% 1.00% 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 year ended August 31, 2003 were as follows: CLASS A CLASS B CLASS C CLASS R Contingent Deferred Sales Charges Imposed $665 $141,882 $1,116 $-- - -------------------------------------------------------------------------------- SHAREHOLDER SERVICING AGENT - MFSC, a wholly owned subsidiary of MFS, earns a fee 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%. Prior to April 1, 2003, the fee was 0.10% of the fund's average daily net assets. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $155,762,365 and $166,476,768, 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 $135,998,596 ------------------------------------------------------------------ Gross unrealized appreciation $14,441,200 ------------------------------------------------------------------ Gross unrealized depreciation (1,244,598) ------------------------------------------------------------------ Net unrealized appreciation $13,196,602 ------------------------------------------------------------------ (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. 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 year ended August 31, 2003 was $442. The fund had no borrowings during the year. - ------------------------------------------------------------------------------- INDEPENDENT AUDITORS' REPORT - ------------------------------------------------------------------------------- To the Trustees of MFS Series Trust I and Shareholders of MFS Research Growth and Income Fund: We have audited the accompanying statement of assets and liabilities of MFS Research Growth and Income Fund (the Fund) (one of the portfolios constituting MFS Series Trust I), including the portfolio of investments, as of August 31, 2003, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. Our procedures included confirmation of securities owned at August 31, 2003, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of MFS Research Growth and Income Fund at August 31, 2003, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the periods indicated therein, in conformity with accounting principles generally accepted in the United States.
