LETTER FROM THE CHAIRMAN
[Photo of Jeffrey L. Shames]
Jeffrey L. Shames
Dear Shareholders,
The current investment and economic environment bears little resemblance to last
year's. One year ago, global economies were floundering, and the crisis in Asia
threatened an already weak U.S. economy. Corporate earnings were flat, and
economists used the word "deflation" for the first time in recent memory.
Entering 1999, expectations for corporate earnings growth were lowered
dramatically. In an attempt to foster U.S. growth, the Federal Reserve Board
(the Fed) lowered interest rates.
As a result, this year the U.S. economy is booming and unemployment is low. Many
corporations are focused on improving their profitability, and investors have
been rewarded with positive surprises across a variety of industries. Our
analysts predict that corporate earnings growth for 1999 will average 12% - 15%.
Global economies also are showing signs of strength, and the Asian crisis has
passed. In fact, Japan's economic woes seem to have reached bottom. Although the
process is in its infancy, some Japanese corporations not only are talking about
restructuring and cost cutting, they also are beginning to take action, looking
within to become more competitive and improve returns on equity. While still
lagging the United States, Europe is beginning to restructure and consolidate.
These signs of international growth have contributed to concerns that the U.S.
economy now may be too strong. In June, and again in August, the Fed raised
rates by one-quarter of a percentage point to help ward off the specter of
inflation.
After an unprecedented four years of 20% annual returns in the U.S. equity
market, we fear that many investors have become accustomed to high returns and
have lost sight of the risks they take on to achieve them. In the current market
many investors are taking on additional risk - whether through day trading or
investing in speculative Internet stocks.
Risks are as much a part of the market today as they were one year ago. We
believe the market remains overvalued, with stocks priced 30% above our
analysts' earnings projections. And market narrowness has not abated; the top 25
stocks in the Standard & Poor's 500 Composite Index, a popular, unmanaged index
of common stock total return performance, are still the most overvalued. Such
extreme overvaluation makes the stock market sensitive to interest-rate news and
any negative earnings surprises. The Year 2000 (Y2K) computer problem is another
factor causing investor concern. While we believe corporate America is well
prepared to address any Y2K situations that may arise at year-end, no one can
predict investor behavior. In our opinion, it is investor behavior that has the
greatest potential to create market volatility.
We believe the best way to address Y2K and other market risks is through our
continuing commitment to MFS Original Research(R) and our fundamental investment
tenet of long-term investing. Whether markets are up or down, MFS analysts focus
on analyzing industries and visiting companies to determine the long-term
winners and the prices that will make them attractive opportunities. Because all
companies will not benefit equally from the improving international environment,
bottom-up research remains critical to identifying those that we believe are
successfully restructuring, consolidating, and gaining market share.
Changes in market and economic conditions can't be predicted but should always
be expected. The changes we have seen over the past year only reinforce our
commitment to long-term planning and investing. We believe volatility helps to
create opportunity for long-term investors to buy solid companies at attractive
prices. For this reason, we are continuing to expand our domestic and
international capabilities to ensure that MFS has primary, in-house research on
companies worldwide. We believe that we have built the right investment team,
backed by MFS Original Research, to take advantage of those opportunities for
our shareholders.
We appreciate your confidence and welcome any questions or comments you may
have.
Respectfully,
/s/ Jeffrey L. Shames

MANAGEMENT REVIEW AND OUTLOOK
[Photo of Alec C. Murray]
Alec C. Murray
For the 12 months ended August 31, 1999, the Fund's Class A shares provided a
total return of 28.64%, Class B shares 27.74%, Class C shares 27.66%, and Class
I shares 28.95%. These returns, which include the reinvestment of any
distributions but exclude the effects of any sales charges, compare to a 39.83%
return over the same period for the Standard & Poor's 500 Composite Index (the
S&P 500), a popular, unmanaged index of common stock total return performance.
The average growth and income fund tracked by Lipper Analytical Services, Inc.,
an independent firm that reports mutual fund performance, returned 31.14% over
the same period.
Q. HOW WOULD YOU DESCRIBE THE MARKET OVER THE PAST YEAR?
A. It has generally been favorable. In the fall of 1998, we were coming off a
pretty severe meltdown brought on by news that the Russian government was
defaulting on its loans and Latin American countries might be devaluing their
currencies. Many investors were shifting out of stocks, and it looked like we
could be headed for a global liquidity crisis. Fortunately, the Federal
Reserve Board stepped in early last fall and lowered short-term interest
rates. This restored investor confidence, and stocks took off in the fourth
quarter of the year. The market continued climbing in the first few months of
1999, with most of the appreciation coming from about 25 growth stocks in the
S&P 500. Then, in April, the market began to broaden thanks to a healthy U.S.
economy and strong international markets. Despite rising interest rates and
some volatility, both economically sensitive and small-company stocks made up
for lost ground during the spring and summer.
Q. WHICH STOCKS DISAPPOINTED DURING THE PERIOD?
A. Supermarkets and drugstores with steady earnings growth looked attractive
last year when only a small group of companies were growing earnings. But as
the earnings of cyclical stocks such as oil and paper started to take off
this past spring, investors began dumping names such as CVS, a drug store
chain, and Kroger, a supermarket chain. Similarly, investors abandoned
consumer stocks for cyclicals. That hurt names like Clorox, whose valuation
(price relative to earnings and other measures) has now fallen so far that it
looks quite attractive. Finally, rising interest rates hurt financial
services stocks, including the Federal Home Loan Mortgage Corporation and the
Federal National Mortgage Association, both of which we sold.
Q. WHAT FACTORS POSITIVELY IMPACTED PERFORMANCE?
A. A few factors. First, we had a sizable stake in technology, focusing on
well-known, quality companies with strong prospects. Stocks that continued to
do well for us were Microsoft, which is coming out with new products later
this year, and Intel, which is enjoying high margins on its new xeon chip. We
also invested heavily in telecommunications stocks, which have benefited from
the huge growth in voice and data communications on the Internet. Some of our
top performers in this area were service stocks such as Bell Atlantic and
Sprint, as well as equipment manufacturers like Cisco Systems. Second, oil
stocks enjoyed a nice rebound due to rising oil prices, industry
consolidation, and cost cutting. Mobil and Exxon, which are in the process of
merging, as well as BP Amoco all did well for us. Finally, strong stock
selection gave us an edge even in sectors that were not market leaders. Two
examples were Bristol-Myers Squibb, which has a promising line-up of new
drugs, and Tyco International, an industrial conglomerate that has done
especially well with its underseas fiber-optic cable business.
Q. HAVE YOU MADE ANY NOTABLE CHANGES TO THE PORTFOLIO OVER THE PAST YEAR?
A. We try to buy companies with great track records and great franchises when
their stocks are selling at reasonable valuations. A year ago we sold Coca-
Cola because we thought it was overpriced relative to its earnings prospects.
The stock price has since tumbled, giving us an opportunity to start
rebuilding our stake in the company. More recently, we took profits in Lucent
and used the proceeds to increase our investment in Cisco, the leading
supplier of routing and switching equipment to Internet service providers. We
believe Cisco represents a better opportunity than Lucent, given the
company's heavy investment in research and development for next- generation
products. We also sold Pfizer, which was one of the highest- priced stocks in
the pharmaceutical industry. We were concerned that market share gains from
both its Celebrex and Viagra products may have peaked, with no new
blockbuster drugs on the horizon.
Q. WHAT'S YOUR OUTLOOK FOR THE MARKET AND CORPORATE EARNINGS IN PARTICULAR?
A. We are optimistic. So far this year the S&P 500 has had double-digit earnings
growth, with more and more companies participating in the gains. We believe
that strong corporate earnings growth will continue, especially if, as
expected, economic growth here remains healthy, inflation stays low, and
consumer spending remains strong. Cyclical stocks with operations in other
countries should do especially well as economies overseas rebound. We expect
the large-company market leaders we invest in to benefit from this favorable
environment.

NOTES TO PERFORMANCE SUMMARY
Class A share ("A") SEC results include the maximum 5.75% sales charge. Class B
share ("B") SEC results reflect the applicable contingent deferred sales charge
(CDSC), which declines over six years from 4% to 0%. Class C shares ("C") have
no initial sales charge but, like B, have higher annual fees and expenses than
A. C SEC results reflect the 1% CDSC applicable to shares redeemed within 12
months. Class I shares ("I") have no sales charge or Rule 12b-1 fees and are
only available to certain institutional investors.
B and C results include the performance and the operating expenses (e.g., Rule
12b-1 fees) of A for periods prior to the inception of B and C. Because
operating expenses of B and C are higher than those of A, B and C performance
generally would have been lower than A performance. The A performance included
in the B and C SEC performance has been adjusted to reflect the CDSC generally
applicable to B and C rather than the initial sales charge generally applicable
to A.
I results include the performance and the operating expenses (e.g., Rule 12b-1
fees) of A for periods prior to the inception of I. Because operating expenses
of A are greater than those of I, I performance generally would have been higher
than A performance. The A performance included in the I performance has been
adjusted to reflect the fact that I have no initial sales charge.
Performance results reflect any applicable expense subsidies and waivers,
without which the results would have been less favorable. Subsidies and waivers
may be rescinded at any time. See the prospectus 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.

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 generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. 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 listed on securities exchanges or
reported through the NASDAQ system are reported at market value using last sale
prices. Unlisted equity securities or listed equity securities for which last
sale prices are not available are reported at market value using last quoted bid
prices. Short-term obligations, which mature in 60 days or less, are valued at
amortized cost, which approximates market value. Securities for which there are
no such quotations or valuations are valued in good faith by the 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.
Deferred Organization Expenses - Costs incurred by the Fund in connection with
its organization have been deferred and are being amortized on a straight-line
basis over a five-year period beginning on the date of commencement of Fund
operations.
Security Loans - State Street Bank and Trust Company ("State Street"), as agent,
may loan the securities of the Fund to certain brokers (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.
At August 31, 1999, the value of securities loaned was $3,134,294. These loans
were collateralized by cash of $3,228,274. Cash collateral is invested in
short-term securities, which are included in the Portfolio of Investments. 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 State Street
in its capacity as lending agent. On loans collateralized by U.S. Treasury
securities, a fee is received from the Borrower, and is allocated between the
Fund and State Street. 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 financial statement and tax reporting purposes as required by
federal income tax regulations. Dividends received in cash are recorded on the
ex-dividend date. Dividend payments received in additional securities are
recorded on the ex-dividend date in an amount equal to the value of the security
on such date.
Fees Paid Indirectly - The Fund's custody fee is calculated as a percentage of
the Fund's month end net assets. The 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 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 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 requires that 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. During
the year ended August 31, 1999, $304,672 and $21,455, respectively, were
reclassified to accumulated net investment loss and accumulated undistributed
net realized gain on investments and foreign currency transactions from paid-in
capital due to differences between book and tax accounting. 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 $500 million of average net assets 0.65%
Average net assets in excess of $500 million 0.55%
The Fund 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 all of its independent Trustees and Mr. Bailey. Included in Trustees'
compensation is a net periodic pension expense of $17,395 for the year ended
August 31, 1999.
Administrator - The Fund has an administrative services agreement with MFS to
provide the Fund with certain financial, legal, shareholder servicing,
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 $1 billion 0.0150%
Next $1 billion 0.0125%
Next $1 billion 0.0100%
In excess of $3 billion 0.0000%
Distributor - MFD, a wholly owned subsidiary of MFS, as distributor, received
$79,429 for the year ended August 31, 1999, 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 up to 0.35% per
annum of its average daily net assets attributable to Class A shares 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 of up to 0.25% per
annum of the Fund's average daily net assets attributable to Class A shares
which are attributable to that securities dealer and a distribution fee to MFD
of up to 0.10% per annum of the Fund's average daily net assets attributable to
Class A shares. The Class A distribution fee is currently being waived on a
voluntary basis and may be imposed at the discretion of MFD. MFD retains the
service fee for accounts not attributable to a securities dealer, which amounted
to $3,244 for the year ended August 31, 1999. Fees incurred under the
distribution plan during the year ended August 31, 1999, were 0.25% of average
daily net assets attributable to Class A shares on an annualized basis.
The Fund's distribution plan provides that the Fund will pay MFD a distribution
fee of 0.75% per annum, and a service fee of up to 0.25% per annum, of the
Fund's average daily net assets attributable to Class B and Class C shares. MFD
will pay to securities dealers that enter into a sales agreement with MFD all or
a portion of the service fee attributable to Class B and Class C shares, and
will pay to such securities dealers all of the distribution fee attributable to
Class C shares. The service fee is intended to be consideration for services
rendered by the dealer with respect to Class B and Class C shares. MFD retains
the service fee for accounts not attributable to a securities dealer, which
amounted to $558 and $175 for Class B and Class C shares, respectively, for the
year ended August 31, 1999. Fees incurred under the distribution plan during the
year ended August 31, 1999, were 1.00% of average daily net assets attributable
to both Class B and Class C shares, on an annualized basis.
Certain Class A and Class C shares are subject to a contingent deferred sales
charge in the event of a shareholder redemption within 12 months following
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 of purchase. MFD receives all contingent deferred sales charges.
Contingent deferred sales charges imposed during the year ended August 31, 1999,
were $1,433, $182,176, and $4,517 for Class A, Class B, and Class C shares,
respectively.
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 0.10%.
Prior to April 1, 1999, the fee was calculated as a percentage of the Fund's
average daily net assets at an annual rate of 0.1125%.

(6) Line of Credit
The Fund and other affiliated funds participate in an $820 million unsecured

agreement. Borrowings may be made to temporarily finance the repurchase of Fund
shares. 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, 1999, was $1,391. The Fund had no

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
To the Trustees of the MFS Series Trust I and the 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), including the schedule of portfolio
investments, as of August 31, 1999, 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
three years in the period then ended, and for the period from January 2, 1996
(commencement of operations) to August 31, 1996. 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 generally accepted auditing
standards. 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, 1999, 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, 1999, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the three years in the period then ended, and for the period from January 2,
1996 (commencement of operations) to August 31, 1996, in conformity with
generally accepted accounting principles.

MFS' YEAR 2000 READINESS DISCLOSURE
MFS Investment Management(R), as an investment adviser and on behalf of the MFS
funds, is committed to the effective use of technology in managing our portfolio
investments, delivering high-quality service to MFS fund shareholders,
retirement plan participants, and MFS' institutional clients, and supporting the
financial consultants who sell our products. With that in mind, we created a
separately funded Year 2000 Program Management Office in 1996 comprised of a
specialized staff reporting directly to MFS senior management.
The Year 2000 (Y2K) problem arises because calendar-year fields in computers and
software applications traditionally have used two-digit codes so that, for
example, the year 1998 is coded as "98," with the "19" being implied. In the
year 2000, unless necessary corrections have been made, computer applications
may assume "00" refers to 1900 rather than 2000, thus resulting in systems
failures or miscalculations. To address this issue, our team of dedicated
business and technology managers, working with outside experts, is taking steps
to ascertain the Y2K readiness of MFS' internal systems and is working with our
external systems vendors to determine whether they expect their systems to be
ready.
MFS recognizes that fund shareholders and institutional clients also are
concerned about whether the companies whose securities are held in their
portfolios are addressing Y2K issues. As part of the MFS Original Research(R)
process of evaluating portfolio investments, one of the many relevant factors
that MFS' portfolio managers and research analysts may consider is a company's
Y2K readiness. Each year, MFS' research analysts and portfolio managers conduct
more than 1,000 on-site meetings with companies whose securities are, or may be,
held in fund and client portfolios, and host an additional 1,500 meetings at
MFS' headquarters. When assessing the Y2K readiness of these companies, MFS'
research analysts and portfolio managers may rely upon discussions at these
meetings as well as SEC disclosure documents and third-party reports.
Y2K readiness is an enormously complex, worldwide issue. No company or
institution can guarantee that it will be unaffected by the Y2K issue. While MFS
is taking significant steps to protect the integrity of its internal systems,
there can be no assurance that these steps will be sufficient to avoid any
adverse impact on MFS, shareholders of MFS funds, participants in retirement
plans administered by MFS, or MFS' institutional clients.

Management Office by e-mail at [email protected] or by letter at 500 Boylston Street,
