MANAGEMENT REVIEW
- -------------------------------------------------------------------------------

Dear Shareholders,

Under normal market conditions, the fund seeks to provide capital appreciation
by investing primarily in common stocks and related securities of companies
whose principal activities are located in Japan, with a focus on companies
with above-average growth potential. 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

Equity Research and are current only through the end of the period of the

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.

FINANCIAL STATEMENTS        FINANCIAL HIGHLIGHTS
- --------------------------------------------------------------------------------------------------------------------------

The financial highlights table is intended to help you understand the fund's financial performance for the period of the
fund's operation. Certain information reflects financial results for a single fund share. The total returns in the table
represent the rate by which an investor would have earned (or lost) on an investment in the fund (assuming reinvestment of
all distributions). This information has been audited by the fund's independent auditors, whose report, together with the
fund's financial statements, are included in this report.

NOTES TO FINANCIAL STATEMENTS
- -------------------------------------------------------------------------------

(1) BUSINESS AND ORGANIZATION

MFS Japan Equity Fund (the fund) is a non-diversified series of MFS Series
Trust I (the trust). The trust is organized as a Massachusetts business trust
and is registered under the Investment Company Act of 1940, as amended, as an
open-end management investment company.

(2) SIGNIFICANT ACCOUNTING POLICIES

GENERAL - The preparation of financial statements in conformity with
accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities, and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts
of revenues and expenses during the reporting period. Actual results could
differ from those estimates.

The fund can invest in foreign securities 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         --

                Other temporary differences                  --

against any net taxable realized gains of each succeeding year until the
earlier of its utilization or expiration on:

                ------------------------------------------------

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.

investments owned by the fund, as computed on a federal income tax basis, are

* For the period from the inception of Class I, July 31, 2002, through

(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.

The Trust does not hold annual shareholder meetings for the purpose of electing Trustees, and Trustees are not
elected for fixed terms. This means that each Trustee will be elected to hold office until his or her
successor is chosen and qualified or until his or her earlier death, resignation, retirement or removal. Each
officer will hold office until his or her successor is chosen and qualified, or until he or she retires,
resigns or is removed from office.

Messrs. Shames, Cohn, Sherratt and Smith, and Ms. O'Neill, have served in their capacity as Trustee of the
Trust continuously since originally elected or appointed. Messrs. Ballen, Gutow, Ives, Perera and Poorvu, and
Ms. Smith, were elected by shareholders and have served as Trustees of the Trust since January 1, 2002. Mr.
Parke has served as a Trustee of the Trust since January 1, 2002.

Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or
a subsidiary is the investment adviser or distributor and, in the case of the officers, with certain
affiliates of MFS. Each Trustee serves as a board member of 110 funds within the MFS Family of Funds.

LETTER FROM THE CHAIRMAN
- -------------------------------------------------------------------------------

Dear Shareholders,

[Photo of Jeffrey L. 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

MANAGEMENT REVIEW
- --------------------------------------------------------------------------------

MARKET ENVIRONMENT

During the period, the fund provided positive returns but lagged its benchmark
on a relative basis. 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

INDEX DEFINITION

RUSSELL 1000 VALUE INDEX - Measures the performance of large-cap U.S.
value stocks.

It is not possible to invest directly in an index.


NOTES TO PERFORMANCE SUMMARY

Class A and 529A results, including sales charge, reflects the deduction of
the maximum 5.75% sales charge. Class B and 529B results, including sales
charge, reflects the deduction of the applicable contingent deferred sales
charge (CDSC), which declines over six years from 4% to 0%. Class C and 529C
results, including sales charge, redeemed within one year from the end of the
calendar month of purchase reflects the deduction of the 1% CDSC. Class I
shares have no sales charges and are available only to certain investors.
Class 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.

The financial highlights table is intended to help you understand the fund's financial performance for the past 5 years (or, if
shorter, the period of the fund's operation). Certain information reflects financial results for a single fund share. The total
returns in the table represent the rate by which an investor would have earned (or lost) on an investment in the fund (assuming
reinvestment of all distributions). This information has been audited by the fund's independent auditors, whose report, together

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

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)

        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%

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

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.

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.

The Trust does not hold annual shareholder meetings for the purpose of electing Trustees, and Trustees are not
elected for fixed terms. This means that each Trustee will be elected to hold office until his or her
successor is chosen and qualified or until his or her earlier death, resignation, retirement or removal. Each
officer will hold office until his or her successor is chosen and qualified, or until he or she retires,
resigns or is removed from office.

Messrs. Shames, Cohn, Sherratt and Smith, and Ms. O'Neill, have served in their capacity as Trustee of the
Trust continuously since originally elected or appointed. Messrs. Ballen, Ives, Perera and Poorvu, and Ms.
Smith, were elected by shareholders and have served as Trustees of the Trust since January 1, 2002. Mr. Parke
has served as Trustee of the Trust since January 1, 2002.

Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or
a subsidiary is the investment adviser or distributor and, in the case of the officers, with certain
affiliates of MFS. Each Trustee serves as a board member of 110 funds within the MFS Family of Funds.

The Statement of Additional Information contains further information about the Trustees and is available
without charge upon request, by calling 1-800-225-2606.

LETTER FROM THE CHAIRMAN
- -------------------------------------------------------------------------------

Dear Shareholders,

[Photo of Jeffrey L. 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

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.

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.

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.


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.

FINANCIAL STATEMENTS        FINANCIAL HIGHLIGHTS
- ------------------------------------------------------------------------------------------------------------------------------

The financial highlights table is intended to help you understand the fund's financial performance for the past 5 years (or, if
shorter, the period of the fund's operation). Certain information reflects financial results for a single fund share. The total
returns in the table represent the rate by which an investor would have earned (or lost) on an investment in the fund (assuming
reinvestment of all distributions). This information has been audited by the fund's independent auditors, whose report,
together with the fund's financial statements, are included in this report.

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 fees are calculated based on each class' average daily net
assets. The maximum distribution and service fees for each class of shares are
as follows:



                           CLASS A     CLASS B     CLASS C     CLASS J     CLASS R     CLASS 529A    CLASS 529B    CLASS 529C

                                                                                              
Distribution Fee            0.10%       0.75%       0.75%       0.75%       0.25%         0.25%         0.75%         0.75%

- -----------------------------------------------------------------------------------------------------------------------------
Total Distribution Plan     0.35%       1.00%       1.00%       1.00%       0.50%         0.50%         1.00%         1.00%

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. 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.

INDEPENDENT AUDITORS' REPORT
- -------------------------------------------------------------------------------

To the Trustees of MFS Series Trust I and Shareholders of
MFS Strategic Growth Fund:

We have audited the accompanying statement of assets and liabilities of MFS
Strategic 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
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.

The Trust does not hold annual shareholder meetings for the purpose of electing Trustees, and Trustees are not
elected for fixed terms. This means that each Trustee will be elected to hold office until his or her
successor is chosen and qualified or until his or her earlier death, resignation, retirement or removal. Each
officer will hold office until his or her successor is chosen and qualified, or until he or she retires,
resigns or is removed from office.

Messrs. Shames, Cohn, Sherratt and Smith, and Ms. O'Neill, have served in their capacity as Trustee of the
Trust continuously since originally elected or appointed. Messrs. Ballen, Ives, Perera and Poorvu, and Ms.
Smith, were elected by shareholders and have served as Trustees of the Trust since January 1, 2002. Mr. Parke
has served as Trustee of the Trust since January 1, 2002.

Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or
a subsidiary is the investment adviser or distributor and, in the case of the officers, with certain
affiliates of MFS. Each Trustee serves as a board member of 110 funds within the MFS Family of Funds.

LETTER FROM THE CHAIRMAN
- -------------------------------------------------------------------------------

Dear Shareholders,

[Photo of Jeffrey L. 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

MANAGEMENT REVIEW
- --------------------------------------------------------------------------------

MARKET ENVIRONMENT

During much of the twelve month period ended August 31, 2003, there was
uncertainty within the marketplace as well as the geopolitical arena. 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.

Respectfully,

 /s/ Edward L. O'Dette                    /s/ Terri A. Vittozzi

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.

KEY RISK CONSIDERATIONS

Investments in the portfolio are not insured or guaranteed by the FDIC or any
other government agency. Although the portfolio seeks to preserve the value of
your investment, it is possible to lose money by investing in the portfolio. The
portfolio's yield will fluctuate with changes in market conditions.

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.

FINANCIAL STATEMENTS        FINANCIAL HIGHLIGHTS
- ------------------------------------------------------------------------------------------------------------------------------

The financial highlights table is intended to help you understand the fund's financial performance for the past 5 years (or, if
shorter, the period of the fund's operation). Certain information reflects financial results for a single fund share. The total
returns in the table represent the rate by which an investor would have earned (or lost) on an investment in the fund (assuming
reinvestment of all distributions). This information has been audited by the fund's independent auditors, whose report,
together with the fund's financial statements, are included in this report.

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%
- ------------------------------------------------------------------------------

- ------------------------------------------------------------------------------
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

- -----------------------------------------------------------------------------------------------


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

- -----------------------------------------------------------------------------------------------

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

- -----------------------------------------------------------------------------------------------


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

- --------------------------------------------------------------------------------

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.

INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------

To the Trustees of MFS Series Trust I and the Shareholders of MFS Cash Reserve
Fund:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of MFS Cash Reserve 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 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.

The Trust does not hold annual shareholder meetings for the purpose of electing Trustees, and Trustees are not
elected for fixed terms. This means that each Trustee will be elected to hold office until his or her
successor is chosen and qualified or until his or her earlier death, resignation, retirement or removal. Each
officer will hold office until his or her successor is chosen and qualified, or until he or she retires,
resigns or is removed from office.

Messrs. Shames, Cohn, Sherratt and Smith, and Mrs. O'Neill, have served in their capacity as Trustee of the Trust
continuously since originally elected or appointed. Messrs. Ballen, Gutow, Ives, Perera and Poorvu, and Ms. Smith,
were elected by shareholders and have served as a Trustees of the Trust since January 1, 2002. Mr. Parke has served
as Trustee of the Trust since January 1, 2002.

Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or
a subsidiary is the investment adviser or distributor and, in the case of the officers, with certain
affiliates of MFS. Each Trustee serves as a board member of 112 funds within the MFS Family of Funds.

LETTER FROM THE CHAIRMAN
- --------------------------------------------------------------------------------

Dear Shareholders,

[Photo of Jeffrey L. 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

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.

Certain information reflects financial results for a single fund share. The total returns in the table represent the rate by
which an investor would have earned (or lost) on an investment in the fund (assuming reinvestment of all distributions).
This information has been audited by the fund's independent auditors, whose report, together with the fund's financial
statements, are included in this report.

(S) The investment adviser voluntarily agreed under a temporary expense reimbursement agreement to pay all of the fund's
   operating expenses, exclusive of management and distribution and service fees from January 1, 2000 through July 30, 2002. In
   consideration, the fund paid the investment adviser a reimbursement fee not greater than 0.40% of average daily net assets.
   Prior to January 1, 2000, the investment adviser and distributor voluntarily waived their fees. In consideration, the fund
   paid the investment adviser a fee not greater than 1.50% of average daily net assets. To the extent actual expenses were

(S) The investment adviser voluntarily agreed under a temporary expense reimbursement agreement to pay all of the fund's
   operating expenses, exclusive of management fee from January 1, 2000 through July 30, 2002. In consideration, the
   fund paid the investment adviser a reimbursement fee not greater than 0.40% of average daily net assets. Prior to
   January 1, 2000, the investment adviser voluntarily waived its fee. To the extent actual expenses were over this

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                                 $--
      ------------------------------------------------------------------

      Unrealized appreciation                                64,564,891

      Other temporary differences                               (46,247)

For federal income tax purposes, the capital loss carryforward may be applied
against any net taxable realized gains of each succeeding year until the
earlier of its utilization or expiration on:

      ------------------------------------------------------------------

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

- ----------------------------------------------------------------------------------------------------------------

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:

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.

The Trust does not hold annual shareholder meetings for the purpose of electing Trustees, and Trustees are not
elected for fixed terms. This means that each Trustee will be elected to hold office until his or her
successor is chosen and qualified or until his or her earlier death, resignation, retirement or removal. Each
officer will hold office until his or her successor is chosen and qualified, or until he or she retires,
resigns or is removed from office.

Messrs. Shames, Cohn, Sherratt and Smith, and Ms. O'Neill, have served in their capacity as Trustee of the
Trust continuously since originally elected or appointed. Messrs. Ballen, Gutow, Ives, Perera and Poorvu, and
Ms. Smith, were elected by shareholders and have served as Trustees of the Trust since January 1, 2002. Mr.
Parke has served as Trustee of the Trust since January 1, 2002.

Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or
a subsidiary is the investment adviser or distributor and, in the case of the officers, with certain
affiliates of MFS. Each Trustee serves as a board member of 110 funds within the MFS Family of Funds.

The Statement of Additional Information contains further information about the Trustees and is available
without charge upon request, by calling 1-800-225-2606.

LETTER FROM THE CHAIRMAN

Dear Shareholders,

[Photo of Jeffrey L. 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

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.

- --------------------------------------------------

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.

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

KEY RISK CONSIDERATIONS

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.

The portfolio may invest a substantial amount of its assets in issuers located
in a limited number of countries and therefore is susceptible to adverse
economic, political or regulatory developments affecting those countries.

These risks may increase share price volatility. Please see the prospectus for
further information regarding these and other risk considerations.

This report is prepared for the general information of shareholders. It is
authorized for distribution to prospective investors only when preceded or
accompanied by a current prospectus.

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.

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%

- ------------------------------------------------------------------------------

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. 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

MFD retains the service fee for accounts not attributable to a securities dealer, which for
the year ended August 31, 2003, amounted to:

- ---------------------------------------------------------------------------------------------


Payment of the 0.15% per annum portion of the Class 529A distribution fee that
is not currently being charged will be implemented on such a date as the
Trustees of the Trust may determine.

Certain Class A, Class C and Class 529C shares are subject to a contingent
deferred sales charge in the event of a shareholder redemption within, for class
A shares, 12 months following the purchase, and, for class C and 529C shares,
the first year from the end of the calendar month of purchase. A contingent
deferred sales charge is imposed on shareholder redemptions of Class B and Class
529B shares in the event of 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

            $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.

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.

INDEPENDENT AUDITORS' REPORT
- -------------------------------------------------------------------------------

To the Trustees of MFS Series Trust I and Shareholders of MFS Research
International Fund:

We have audited the accompanying statement of assets and liabilities of MFS
Research International 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 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.

The Trust does not hold annual shareholder meetings for the purpose of electing Trustees, and Trustees are not
elected for fixed terms. This means that each Trustee will be elected to hold office until his or her
successor is chosen and qualified or until his or her earlier death, resignation, retirement or removal. Each
officer will hold office until his or her successor is chosen and qualified, or until he or she retires,
resigns or is removed from office.

Messrs. Shames, Ives, Perera and Poorvu, and Ms. Smith, have served in their capacity as Trustee of the Trust
continuously since originally elected or appointed. Messrs. Ballen and Gutow have each served as a Trustee of
the Trust since August 1, 2001. Messrs. Cohn, Sherratt and Smith, and Ms. O'Neill, were elected by
shareholders and have served as Trustees of the Trust since January 1, 2002. Mr. Parke has served as Trustee
of the Trust since January 1, 2002.

Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or
a subsidiary is the investment adviser or distributor and, in the case of the officers, with certain
affiliates of MFS. Each Trustee serves as a board member of 112 funds within the MFS Family of Funds.

LETTER FROM THE CHAIRMAN

Dear Shareholders,

[Photo of Jeffrey L. 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

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.

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.

** Effective February 28, 2003, the Russell 1000 Growth Index has replaced the
   Russell 3000 Growth Index as the fund's benchmark. We believe the Russell
   1000 Growth Index more accurately reflects the fund's large cap growth
   discipline, offering investors a more reliable objective measure of the

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.

This report is prepared for the general information of shareholders. It is
authorized for distribution to prospective investors only when preceded or

The financial highlights table is intended to help you understand the fund's financial performance for the past 5 years (or, if
shorter, the period of the fund's operation). Certain information reflects financial results for a single fund share. The total
returns in the table represent the rate by which an investor would have earned (or lost) on an investment in the fund (assuming
reinvestment of all distributions). This information has been audited by the fund's independent auditors, whose report,
together with the fund's financial statements, are included in this report.

  # Per share data is based on average shares outstanding.
 ## Ratios do not reflect reductions from fees paid indirectly.
(+) Total returns for Class A shares do not include the applicable sales charge. If the charge had been included, the results
    would have been lower.
(S) The fund's total return calculation includes a payment received from a non-recurring litigation settlement recorded as a
    realized gain in the Statement of Operations. Excluding the effect of this payment from the fund's ending net asset value
    per share, total return for the year ended August 31, 2003 would have been 12.79%.

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.

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.

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:

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

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.

The Trust does not hold annual shareholder meetings for the purpose of electing Trustees, and Trustees are not
elected for fixed terms. This means that each Trustee will be elected to hold office until his or her
successor is chosen and qualified or until his or her earlier death, resignation, retirement or removal. Each
officer will hold office until his or her successor is chosen and qualified, or until he or she retires,
resigns or is removed from office.

Messrs. Shames, Cohn, Sherratt and Smith, and Ms. O'Neill, have served in their capacity as Trustee of the
Trust continuously since originally elected or appointed. Messrs. Ballen, Gutow, Ives, Perera and Poorvu, and
Ms. Smith, were elected by shareholders and have served as Trustees of the Trust since January 1, 2002. Mr.
Parke has served as Trustee of the Trust since January 1, 2002.

Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or
a subsidiary is the investment adviser or distributor and, in the case of the officers, with certain
affiliates of MFS. Each Trustee serves as a board member of 110 funds within the MFS Family of Funds.

The Statement of Additional Information contains further information about the Trustees and is available
without charge upon request, by calling 1-800-225-2606.

LETTER FROM THE CHAIRMAN

Dear Shareholders,

[Photo of Jeffrey L. 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

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.

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.

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.

FINANCIAL STATEMENTS        FINANCIAL HIGHLIGHTS
- ------------------------------------------------------------------------------------------------------------------------------

The financial highlights table is intended to help you understand the fund's financial performance for the past 5 years (or, if
shorter, the period of the fund's operation). Certain information reflects financial results for a single fund share. The total
returns in the table represent the rate by which an investor would have earned (or lost) on an investment in the fund (assuming
reinvestment of all distributions). This information has been audited by the fund's independent auditors, whose report,
together with the fund's financial statements, are included in this report.

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%

- ------------------------------------------------------------------------------

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

MFD retains the service fee for accounts not attributable to a securities dealer, which for the year
ended August 31, 2003, amounted to:

- --------------------------------------------------------------------------------------------------


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

- --------------------------------------------------------------------------------

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. 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.

(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. A commitment fee of $7,639 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.

(7) RESTRICTED SECURITIES

The fund may invest not more than 15% of its total assets in securities which
are subject to legal or contractual restrictions on resale. At August 31, 2003,
the New Discovery Fund owned the following restricted securities, excluding
securities issued under Rule 144A, constituting 0.89% of net assets which may
not be publicly sold without registration under the Securities Act of 1933. The
fund does not have the right to demand that such securities be registered. The
value of these securities is determined by valuations furnished by dealers or by
a pricing service, or if not available, in good faith at the direction of the
Trustees.

INDEPENDENT AUDITORS' REPORT
- -------------------------------------------------------------------------------

To the Trustees of MFS Series Trust I and the Shareholders of
MFS New Discovery Fund:

We have audited the accompanying statement of assets and liabilities of MFS
New Discovery 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
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.

The Trust does not hold annual shareholder meetings for the purpose of electing Trustees, and Trustees are not
elected for fixed terms. This means that each Trustee will be elected to hold office until his or her
successor is chosen and qualified or until his or her earlier death, resignation, retirement or removal. Each
officer will hold office until his or her successor is chosen and qualified, or until he or she retires,
resigns or is removed from office.

Messrs. Shames, Cohn, Sherratt and Smith, and Mrs. O'Neill, have served in their capacity as Trustee of the Trust
continuously since originally elected or appointed. Messrs. Ballen, Gutow, Ives, Perera and Poorvu, and Ms. Smith,
were elected by shareholders and have served as Trustees of the Trust since January 1, 2002. Mr. Parke has served
as Trustee of the Trust since January 1, 2002.

Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or
a subsidiary is the investment adviser or distributor and, in the case of the officers, with certain
affiliates of MFS. Each Trustee serves as a board member of 110 funds within the MFS Family of Funds.

The Statement of Additional Information contains further information about the Trustees and is available
without charge upon request, by calling 1-800-225-2606.

LETTER FROM THE CHAIRMAN
- -------------------------------------------------------------------------------

Dear Shareholders,

[Photo of Jeffrey L. 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.

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.

INDEX DEFINITIONS

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

MERRILL LYNCH 100 TECHNOLOGY INDEX - The Merrill Lynch 100 Technology Index is
a broad measure of the technology sector.

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.

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.

The financial highlights table is intended to help you understand the fund's financial performance for the past 5 years (or, if
shorter, the period of the fund's operation). Certain information reflects financial results for a single fund share. The total
returns in the table represent the rate by which an investor would have earned (or lost) on an investment in the fund (assuming
reinvestment of all distributions). This information has been audited by the fund's independent auditors, whose report,
together with the fund's financial statements, are included in this report.

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.

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%

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.

(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.

The Trust does not hold annual shareholder meetings for the purpose of electing Trustees, and Trustees are not
elected for fixed terms. This means that each Trustee will be elected to hold office until his or her
successor is chosen and qualified or until his or her earlier death, resignation, retirement or removal. Each
officer will hold office until his or her successor is chosen and qualified, or until he or she retires,
resigns or is removed from office.

Messrs. Shames, Cohn, Sherratt and Smith, and Ms. O'Neill, have served in their capacity as Trustee of the
Trust continuously since originally elected or appointed. Messrs. Ballen, Gutow, Ives, Perera and Poorvu, and
Ms. Smith, were elected by shareholders and have served as Trustees of the Trust since January 1, 2002. Mr.
Parke has served as Trustee of the Trust since January 1, 2002.

Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or
a subsidiary is the investment adviser or distributor and, in the case of the officers, with certain
affiliates of MFS. Each Trustee serves as a board member of 110 funds within the MFS Family of Funds.

LETTER FROM THE CHAIRMAN
- --------------------------------------------------------------------------------

Dear Shareholders,

[Photo of Jeffrey L. 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,

MANAGEMENT REVIEW
- -------------------------------------------------------------------------------

MARKET ENVIRONMENT

The 12-month period ended August 31, 2003 was marked by 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 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.

- -----------------------------------------------

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.

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.

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.

The financial highlights table is intended to help you understand the fund's financial performance for the past 5 years.
Certain information reflects financial results for a single fund share. The total returns in the table represent the rate by
which an investor would have earned (or lost) on an investment in the fund (assuming reinvestment of all distributions). This
information has been audited by the fund's independent auditors, whose report, together with the fund's financial statements,
are included in this report.

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

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                                 $--
      ------------------------------------------------------------------

      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.

      ------------------------------------------------------------------

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           $--
- --------------------------------------------------------------------------------

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.

The Trust does not hold annual shareholder meetings for the purpose of electing Trustees, and Trustees are not
elected for fixed terms. This means that each Trustee will be elected to hold office until his or her
successor is chosen and qualified or until his or her earlier death, resignation, retirement or removal. Each
officer will hold office until his or her successor is chosen and qualified, or until he or she retires,
resigns or is removed from office.

Messrs. Shames, Cohn, Sherratt and Smith, and Ms. O'Neill, have served in their capacity as Trustee of the
Trust continuously since originally elected or appointed. Messrs. Ballen, Gutow, Ives, Perera and Poorvu, and
Ms. Smith, were elected by shareholders and have served as Trustees of the Trust since January 1, 2002. Mr.
Parke has served as Trustee of the Trust since January 1, 2002.

Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or
a subsidiary is the investment adviser or distributor and, in the case of the officers, with certain
affiliates of MFS. Each Trustee serves as a board member of 110 funds within the MFS Family of Funds.

The Statement of Additional Information contains further information about the Trustees and is available
without charge upon request, by calling 1-800-225-2606.
