LETTER FROM THE CHAIRMAN

Dear Shareholders:
An unprecedented combination of generally positive factors has helped the U.S.
economy enjoy a sustained period of relative stability and moderate growth in
which thousands of new jobs have been created every month, inflation remains
under control, and the investment climate -- at least until now -- has been
favorable. For example, the increased use of technology and other productivity
enhancements, as well as corporate restructuring and global competition, is
improving companies' balance sheets and helping control inflation. Meanwhile,
borrowing by corporations and governments continues to decline, while consumer
confidence is increasing, although consumer debt levels are still
uncomfortably high. While some lenders are beginning to tighten standards to
address this problem, consumer debt and personal bankruptcies continue to
rise. The rapid pace of growth seen in the first quarter slowed slightly in
the second quarter, to an annual rate of 3.3%. While real (inflation-adjusted)
growth could moderate further in the third quarter, we believe economic
momentum will carry well into the first quarter of 1998. The money supply is
increasing at a rapid rate, the housing and automobile markets are
strengthening, and it now appears that Christmas sales could be quite good.
Because economic growth continues to be impressive, markets are likely to
begin focusing on the Federal Reserve Board's (the Fed's) willingness to raise
interest rates.

Although the U.S. equity market has seen increased price volatility of late,
we have been surprised by its overall strength thus far in 1997. Much of this
is the result of continuing gains in corporate earnings. Even as the current
recovery enters its seventh year, more and more U.S. companies have been
exceeding analysts' earnings estimates. In the first quarter of 1997, for
example, two-thirds of all companies met or exceeded analysts' expectations, a
trend that could be an important indicator of the U.S. equity market's future
direction. However, while the near-term outlook for profits is generally
favorable, we believe equity valuations have risen to a point where a cautious
investment approach seems warranted.

In the fixed-income markets, we have been encouraged by the Fed's decision at
its July meeting not to raise short-term interest rates. But we cannot rule
out the possibility of future monetary tightening in the second half of the
year if, as we now expect, the economy strengthens during the balance of 1997.
Therefore, our risk/reward outlook for the fixed-income markets is neutral,
and we believe that fixed-income investors should think in terms of earning
the coupon income from their investments rather than seeking possible gains
from price appreciation.

We appreciate your support and welcome any questions or comments you may have.

    Respectfully,

/s/ A. Keith Brodkin

PORTFOLIO MANAGERS' OVERVIEWS

MFS Core Growth Fund
For the 12 months ended August 31, 1997, Class A shares of the Fund provided a
total return of 45.22%, and Class I shares returned 45.31%. These returns, which
assume the reinvestment of distributions but exclude the effects of any sales
charges, compare to a 40.78% return for the Standard & Poor's 500 Composite
Index (the S&P 500), a popular, unmanaged index of common stock total return
performance.

Four general themes best describe the Fund's current holdings, which are built
from the bottom up based on individual stock selection. First, the Fund seeks
companies with high unit sales growth that can support above-average revenue
growth. Second, the Fund looks for companies that we believe could exhibit
accelerated earnings growth driven by new product cycles and/or acquisitions
that contribute to growth. Third, the Fund seeks companies that seem able to
control their own destinies through internal changes such as cost cutting or
consolidation. This encompasses companies with the potential to make higher-
than-average levels of incremental internal investment. Finally, the Fund seeks
companies that, in our opinion, have the potential to benefit from a fundamental
mismatch in the balance between supply and demand.

Positions in several industry sectors have been added to the Fund or have been
increased in recent months, including drug store chains, in which we expect to
see growth as the population ages, and entertainment companies, in which
consolidations are continuing. We have also increased the Fund's holdings in the
oil service sector, which is benefiting from a mismatch in supply and demand, as
well as in package delivery companies, which are capitalizing on the strong
economy and wage pressures at United Parcel Service.

MFS Equity Income Fund
For the 12 months ended August 31, 1997, Class A shares of the Fund provided a
total return of 38.05%, and Class I shares returned 37.95%. These returns, which
assume the reinvestment of distributions but exclude the effects of any sales
charges, compare to a 40.78% return for the S&P 500.

The Fund's top holdings remain in the financial services, utilities, energy, and
industrial goods and services sectors. Within financial services, the Fund
remains heavily weighted in insurance stocks, in which restructuring and
consolidation are leading to improved returns and better valuations. The Fund's
utility holdings are concentrated in gas distribution companies, high-quality,
low-cost electric utilities, and well-positioned local and long-distance
telephone companies. Essentially, the Fund is seeking to invest in companies
that we believe are well insulated from heightened competition and/ or companies
that may benefit from continuing consolidation in these industries. The energy
sector remains a key one for the Fund, especially those companies that are
dedicated to increasing production, cutting costs, and improving returns in
lagging businesses such as refining. Pollution control is a growing portion of
the Fund's holdings in industrial goods and services. This industry has
underperformed the market for several years but is now refocusing on its core
business, embracing cost cutting, and allocating capital more carefully.

The Fund continues to seek holdings in companies that we believe provide
attractive dividend yields and reasonable valuations, characteristics that we
feel could provide protection against price declines in a volatile market.

MFS Special Opportunities Fund
For the 12 months ended August 31, 1997, Class A shares of the Fund provided a
total return of 31.84%, and Class I shares returned 32.23%. These returns, which
assume the reinvestment of distributions but exclude the effects of any sales
charges, compare to a 40.78% return for the S&P 500 and to a 15.55% return for
the average high-yield corporate bond fund as tracked by CDA/ Wiesenberger, an
independent firm that reports mutual fund performance.

The Fund continues to have the majority of its assets in common stocks because
we have found few attractive investments in the distressed and high-yield
markets. The Fund's investment strategy continues to incorporate both growth
and value disciplines. We have found investment opportunities in companies
that have recently emerged from bankruptcy, companies with financially
leveraged capital structures but with strong cash flow and solid earnings
prospects, and companies with attractive growth prospects but with valuations
that don't fully reflect these prospects. Our overall stock market perspective
continues to be cautious; however, we have been able to find an adequate
number of special situations for investment. The weighting of high-yield and
distressed bonds is likely to increase as more-appealing investment ideas
become available.

MFS Blue Chip Fund
The Fund commenced operations on January 2, 1997, and from that date through
August 31, 1997, both Class A and Class I shares provided total returns of
17.70%. These returns, which include the reinvestment of distributions but
exclude the effects of any sales charges, compare to a 22.91% return for the S&P
500 for the same period.

The Fund's investment strategy continues to be predicated on the assumption that
the global economy will grow slowly during 1998 and that U.S. interest rates
will remain fairly stable. In the United States, this assumption is supported by
the longevity of the current economic recovery and the high levels of consumer
debt. Economic growth remains moderate in a good part of Europe. Double-digit
unemployment rates in France (in addition to tax increases) and Germany should
prevent these economies from accelerating. Japan is weak, and economic growth in
other Asian countries could slow as interest rates rise.

The Fund is positioned relatively defensively, with the bulk of its investments
in companies that we believe can sustain double-digit earnings growth in a
slow-growth environment. Earnings ultimately drive stock prices, and investors
will bid up the share prices of companies that can achieve above-average
earnings growth.

The Fund's holdings are diverse and spread across many industries. However,
consistent with this defensive posture, the Fund continues to be overweighted in
the consumer staples and health care sectors. Conversely, the Fund is
significantly underweighted in basic materials and automobiles and housing. The
industrial goods sector is overweighted but aerospace and defense companies have
been emphasized. We believe this sector should perform relatively well in a
slow-growth economy. Similarly, the retail weighting is greater than the
market's, but all of this is in supermarkets and drug stores. The financial
services sector is overweighted, with an emphasis on high-quality regional banks
and insurance companies. The weightings in energy and utilities and
communications approximate those of the market, with the primary energy holdings
being large multinational oil companies. While the utility holdings offer modest
price appreciation, they are viewed as the ballast in the portfolio and
contribute to the Fund's yield. Emphasis has also been placed on companies that
have significant recurring revenue streams and/or that participate in dynamic,
high-growth markets. Examples would be First Data, DST Systems, and Service
Corporation International. For the same reasons, the bulk of the Fund's
technology investments are in the software industry.

MFS Convertible Securities Fund
The Fund commenced operations on January 2, 1997, and from that date through
August 31, 1997, its Class A shares provided a total return of 14.70%, while its
Class I shares returned 14.60%. These returns, which assume the reinvestment of
distributions but exclude the effects of any sales charges, compare to a 15.98%
return for the Merrill Lynch All Convertibles Index, an unmanaged index of
convertible securities, and to a 14.48% return for the average convertible
securities fund for the same period as tracked by Lipper Analytical Services,
Inc., an independent firm that reports mutual fund performance.

The Fund is taking an extremely defensive posture due to the stock market's
current high valuation and its increased volatility in order to preserve
capital. Convertible securities comprise 80% of the portfolio, versus the
required 65% minimum. Increased demand for the convertible asset class has led
to a more expensive convertible market, as illustrated by the aggressive pricing
of new issues. In response, the portfolio is skewed toward convertibles that are
technically cheap; that is, those whose price movements correlate well with
upward price movements in the underlying common stock and that have
above-average yield.

The Fund's overall strategy is to invest in companies that we believe are
benefiting from one or more of the following trends: industry consolidation,
market dominance, and cost containment. Performance was favorably impacted by
overweightings in industrial goods and services companies, including Browning
Ferris, Corning, and U.S. Filter; leisure companies, which included American
Radio Systems and Royal Caribbean Cruises; financial services companies such as
Frontier Insurance and MGIC Investment Corp.; and technology companies,
including Baan and Data General. Conversely, companies in the basic materials
sector, such as RMI Titanium and Titanium Metals, detracted from year-to-date
performance. A value-oriented approach will continue to be used to evaluate
company fundamentals and the technical aspects of convertible securities.

MFS New Discovery Fund
The Fund commenced operations on January 2, 1997, and from that date through
August 31, 1997, its Class A shares provided a total return of 30.70%, while its
Class I shares returned 30.80%. These returns, which assume the reinvestment of
distributions but exclude the effects of any sales charges, compare to a 17.97%
return for the Russell 2000 Total Return Index, an unmanaged index comprised of
2,000 of the smallest U.S.-domiciled company common stocks that are traded on
the New York Stock Exchange, the American Stock Exchange, and NASDAQ.

The Fund invests principally in the shares of emerging companies that we believe
have the potential to grow into large enterprises. We maintain significant
weightings in the technology, health care, lodging, media, and business and
information services industries. We regard these as fundamentally attractive
sectors within which innovative and well-managed companies can be expected to
experience sustainable unit and earnings growth well above that seen in the
broader economy.

Among the factors contributing to the Fund's favorable performance were gains in
the shares of Summit Design, a provider of electronic design and automation
software, and Idexx Laboratories, a manufacturer of veterinary diagnostics
equipment and consumables. In addition, advances were recorded by broadcasters
American Radio Systems and Jacor Communications. The portfolio also benefited
from appreciation in the shares of Affiliated Computer Services and in high- end
hotel operators such as Wyndham, Renaissance, and Doubletree hotels.

Our research efforts continue to identify many attractively valued, emerging
growth companies that we believe can deliver exceptional long-term returns.
This, coupled with a market backdrop that suggests the potential for renewed
interest in smaller-company shares, makes us optimistic about performance
prospects for the year ahead.

MFS Research International Fund
The Fund commenced operations on January 2, 1997, and from that date through
August 31, 1997, both Class A and Class I shares provided total returns of
9.60%. These returns, which assume the reinvestment of distributions but exclude
the effects of any sales charges, compare to a 4.39% return for the Morgan
Stanley Capital International EAFE (Europe, Australia, Far East) Index, an
unmanaged index of international stocks.

The top five sectors in the Fund are financial services (at 14.8% of assets),
technology (12.1%), utilities and communications (11.8%), leisure (11.0%), and
industrial goods and services (9.3%). The three top holdings are Nippon
Broadcasting, Secom, and Canon. Nippon Broadcasting is the world's largest radio
network operating company and has held the top audience ratings in Japan for the
past 22 years. We believe the company can continue to increase earnings by 10%
to 15% per year over the next several years. Secom holds a dominant 60% market
share of the electronic security market in Japan and holds over a 70% market
share through subsidiaries in Korea, Taiwan, Thailand, Malaysia, and Singapore.
We expect Canon's underlying operating growth to be at 12% in the coming year.
The company's valuation is currently cheap for a quality growth company.

In the technology sector, Sony's new digital product launches and strong product
pipeline continue to offer the company significant opportunity, while its new
management's compensation is directly tied to the company's performance. Through
major distributors in Europe and Japan, Sony Pictures will soon exploit the
3,400 movie titles it has in its motion picture bank. As a result, we expect
operating profits to grow at an average of over 20% over the next couple of
years.

Within the financial services sector, several banks and insurance companies in
Hong Kong, Great Britain, France, and Japan continue to demonstrate good
earnings growth that, coupled with substantial cost savings, should yield
excellent results.

The Fund is based upon the international research analysts' best ideas within
their industries. Stocks are selected after careful, in-depth, fundamental
analysis of companes' earnings outlooks. Although each analyst incorporates
general economic forecasts into his or her decision-making process, ultimately,
stocks selected for the Fund represent companies that the analysts believe offer
the best possibilities for capital appreciation regardless of the economic
outlook. These companies typically demonstrate dominant and/or growing market
share, quality new and existing products, superior management teams, and strong
financial statements. Sector and industry weightings are a result of the "best
ideas" stock-selection process. However, the analysts revisit weightings
regularly to assure agreement within the changing economic landscape. We will
continue to use a bottom-up, fundamental approach to investing in companies for
the Fund.

MFS Science and Technology Fund
The Fund commenced operations on January 2, 1997, and from that date through
August 31, 1997, both Class A and Class I shares provided total returns of
25.30%. These returns, which assume the reinvestment of distributions but
exclude the effects of any sales charges, compare to a 23.44% return for the
NASDAQ Composite Index, an unmanaged index of common stocks traded on NASDAQ,
and to a 19.78% return for the average technology fund as tracked by CDA/
Wiesenberger, an independent firm that reports mutual fund performance.

The Fund continues to seek companies that we believe are fast growing, have
market share leadership, and have a defensible strategic position. Holdings
remain focused in the computer software, networking, business services, and
semiconductor areas. To date, the Fund has not made significant investments in
the health care sector.

The Fund's performance has been favorably impacted by stock selection and by a
generally strong technology market. The volatility of the technology sector has
also provided attractive buying opportunities during times of price weakness.
Top holdings include Oracle Systems, Microsoft, and Computer Associates
International. All three of these stocks have seen outstanding price
appreciation driven by a healthy industry environment and by each management's
ability to deliver superior financial results. We believe the outlook for the
technology sector remains highly attractive, while the outlook for the health
care sector should start to improve.

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.

Class I shares, which became available on January 2, 1997, have no sales charge
or Rule 12b-1 fees and are only available to certain institutional investors.
Class I share results include the performance and the operating expenses of
Class A shares for periods prior to the commencement of offering of Class I
shares. Because operating expenses attributable to Class A shares are greater
than those of Class I shares, Class I share performance generally would have
been higher than Class A share performance. The Class A share performance
included within the Class I share performance has been adjusted to reflect the
fact that Class I shares have no initial sales charge.

Performance results reflect any applicable expense subsidies and waivers,
without which the results would have been less favorable. Current subsidies and
waivers may be discontinued at any time.

NOTES TO FINANCIAL STATEMENTS

(1) Business and Organization
MFS Core Growth Fund, MFS Equity Income Fund, MFS Special Opportunities Fund,
MFS Blue Chip Fund, MFS Convertible Securities Fund, MFS New Discovery Fund, MFS
Research International Fund, MFS Science and Technology Fund are diversified
series of MFS Series Trust I (the Trust), and MFS Special Opportunities Fund is
a non-diversified series of 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.

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. Debt securities (other than short-term obligations which mature in 60
days or less), including listed issues and forward contracts and interest rate
swaps, are valued on the basis of valuations furnished by dealers or by a
pricing service with consideration to factors such as institutional-size trading
in similar groups of securities, yield, quality, coupon rate, maturity, type of
issue, trading characteristics, and other market data, without exclusive
reliance upon exchange or over-the-counter prices. 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. Short-term obligations,
which mature in 60 days or less, are valued at amortized cost, which
approximates market value. Futures contracts, options, and options on futures
contracts listed on commodities exchanges are reported at market value using
closing settlement prices. Over-the-counter options on securities are valued by
brokers. Over-the-counter currency options are valued through the use of a
pricing model which takes into account foreign currency exchange spot and
forward rates, implied volatility, and short-term repurchase rates. Securities
for which there are no such quotations or valuations are valued at fair value as
determined in good faith by or at the direction of 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 result from fluctuations in foreign currency exchange rates is not
separately disclosed.

Deferred Organization Expenses - Costs incurred by each 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 each
Fund's operations.

Forward Foreign Currency Exchange Contracts - Each 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. Each Fund will enter into
forward contracts for hedging purposes as well as for non-hedging purposes. For
hedging purposes, each Fund may enter into contracts to deliver or receive
foreign currency they will receive from or require for their normal investment
activities. They 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, each Fund may enter into
contracts with the intent of changing the relative exposure of each 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.

Written Options - Each Fund may also write call or put options in exchange for a
premium. The premium is initially recorded as a liability which is subsequently
adjusted to the current value of the options contract. When a written option
expires, each Fund realizes a gain equal to the amount of the premium received.
When a written call option is exercised or closed, the premium received is
offset against the proceeds to determine the realized gain or loss. When a
written put option is exercised, the premium reduces the cost basis of the
security purchased by each Fund. Each Fund, as writer of an option, may have no
control over whether the underlying securities may be sold (call) or purchased
(put) and, as a result, bears the market risk of an unfavorable change in the
price of the securities underlying the written option. In general, written call
options may serve as a partial hedge against decreases in value in the
underlying securities to the extent of the premium received. Written options may
also be used as part of an income producing strategy reflecting the view of each
Fund's management on the direction of interest rates.

Short Sales - The Special Opportunities Fund, the Convertible Securities Fund,
the New Discovery Fund, and the Science and Technology Fund may enter into short
sales. A short sale transaction involves selling a security which a Fund does
not own with the intent of purchasing it later at a lower price. A Fund will
realize a gain if the security price decreases and a loss if the security price
increases between the date of the short sale and the date on which a Fund must
replace the borrowed security. Losses can exceed the proceeds from short sales
and can be greater than losses from the actual purchase of a security. The
amount of any gain will be decreased, and the amount of any loss increased, by
the amount of the premium, dividends or interest a Fund may be required to pay
in connection with a short sale. Whenever a Fund engages in short sales, its
custodian segregates cash or marketable securities in an amount that, when
combined with the amount of collateral deposited with the broker in connection
with the short sale, at least equals the current market value of the security
sold short.

Investment Transactions and Income - Investment transactions are recorded on the
trade date. Interest income is recorded on the accrual basis. All premium and
original issue discount is amortized or accreted for financial statement and tax
reporting purposes as required by federal income tax regulations. Dividends
received in cash are recorded on the ex-dividend date. Dividend and interest
payments received in additional securities are recorded on the ex- dividend or
ex-interest date in an amount equal to the value of the security on such date.

The Special Opportunities Fund and the Convertible Securities Fund may invest up
to 100% of its portfolio in high-yield securities rated below investment grade.
Investments in high-yield securities involve greater degrees of credit and
market risk than investments in higher-rated securities, and tend to be more
sensitive to economic conditions.

The Funds use the effective interest method for reporting interest income on
payment-in-kind (PIK) bonds. Legal fees and other related expenses incurred to
preserve and protect the value of a security owned are added to the cost of the
security; other legal fees are expensed. Capital infusions, which are generally
non-recurring, incurred to protect or enhance the value of high-yield debt
securities, are reported as additions to the cost basis of the security. Costs
that are incurred to negotiate the terms or conditions of capital infusions or
that are expected to result in a plan of reorganization are reported as realized
losses. Ongoing costs incurred to protect or enhance an investment, or costs
incurred to pursue other claims or legal actions, are expensed.

Fees Paid Indirectly - Each Fund's custody fee is calculated as a percentage of
each Fund's average daily net assets. The fee is reduced according to an
arrangement which measures the value of cash deposited with the custodian by
each Fund. This amount is shown as a reduction of expenses on the Statement of
Operations.

Tax Matters and Distributions - Each 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. Each Fund files a tax
return annually using tax accounting methods required under provisions of the
Code which may differ from generally accepted accounting principles, the basis
on which these financial statements are prepared. Accordingly, the amount of net
investment income and net realized gain reported on these financial statements
may differ from that reported on each Fund's tax return and, consequently, the
character of distributions to shareholders reported in the financial highlights
may differ from that reported to shareholders on Form 1099-DIV.

Distributions to shareholders are recorded on the ex-dividend date. Each 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 a tax return of 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 accumulated net realized
gains.

During the year ended August 31, 1997, the following amounts were reclassified
between accumulated undistributed net investment income and accumulated net
realized gain on investments due to differences between book and tax accounting
for currency transactions. These changes had no effect on the net assets or net
asset value per share.

purposes, had a capital loss carryforward of $1,022 which may be applied against
any net taxable realized gains of each succeeding year until the earlier of its
utilization or expiration on August 31, 2005.

Multiple Classes of Shares of Beneficial Interest - The Funds offer multiple
classes of shares. The classes of shares differ in their respective distribution
and service fees. All shareholders bear the common expenses of each Fund pro
rata based on average daily net assets of each class, without distinction
between share classes. Dividends are declared separately for each class. No
class has preferential dividend rights; differences in per share dividend rates
are generally due to differences in separate class expenses.

(3) Transactions with Affiliates
Investment Adviser - Each 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 effective annual rate of
0.65% of average daily net assets for the Blue Chip Fund and the Convertible
Securities Fund, at an annual rate of 0.75% of average daily net assets for the
Core Growth Fund, the Equity Income Fund, the New Discovery Fund, the Science
and Technology Fund, and the Special Opportunities Fund, and at an annual rate
of 1.00% of average daily net assets for the Research International Fund. For
the year ended August 31, 1997, the investment adviser did not impose any of its
fee, which is reflected as a reduction of expenses in the Statement of
Operations.

Each Fund has a temporary expense reimbursement agreement whereby MFS has
voluntarily agreed to pay all of each Fund's operating expenses, exclusive of
management, distribution and service fees. Each Fund in turn will pay MFS an
expense reimbursement fee not greater than 1.50% of average daily net assets,
except that the Research International Fund will pay a fee of 1.75%. To the
extent that the expense reimbursement fee exceeds each Fund's actual expenses,
the excess will be applied to amounts paid by MFS in prior years. At August 31,
1997, the aggregate unreimbursed expenses owed to MFS by each Fund amounted to:

Each Fund pays no compensation directly to its Trustees who are officers of the
investment adviser, or to officers of each Fund, all of whom receive
remuneration for their services to each Fund from MFS. Certain officers and
Trustees of each Fund are officers or directors of MFS, MFS Fund Distributors,
Inc. (MFD), and MFS Service Center, Inc. (MFSC). The Trustees are currently not
receiving any payments for their services to each Fund.

Administrator - Effective March 1, 1997, the Funds have 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 Funds pay
MFS an administrative fee at the following annual percentages of the Fund's
average daily net assets, provided that the administrative fee is not assessed
on Fund assets that exceed $3 billion:

                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, did not
receive any sales charges on sales on Class A shares of each Fund for the year
ended August 31, 1997.

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:

Each Fund's distribution plan provides that each Fund will pay MFD up to 0.50%
per annum of its average daily net assets attributable to Class A shares in
order that MFD may pay expenses on behalf of each Fund related to the
distribution and servicing of its shares. These expenses include a service fee
to each securities dealer that enters into a sales agreement with MFD of up to
0.25% per annum of each Fund's average daily net assets attributable to Class A
shares which are attributable to that securities dealer, a distribution fee to
MFD of up to 0.25% per annum of each Fund's average daily net assets
attributable to Class A shares, commissions to dealers and payments to MFD
wholesalers for sales at or above a certain dollar level, and other such
distribution-related expenses that are approved by each Fund. Distribution and
service fees under the Class A distribution plan are currently being waived.

Purchases over $1 million of Class A shares and certain purchases by retirement
plans are subject to a contingent deferred sales charge in the event of a
shareholder redemption within 12 months following such purchase. There were no
contingent deferred sales charges imposed during the year ended August 31, 1997,
on Class A shares of each Fund.

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 average daily net assets of each Fund at an effective annual
rate of up to 0.13%. Prior to January 1, 1997, the fee was calculated as a
percentage of the average daily net assets of Class A shares at an effective
annual rate of up to 0.15%. MFSC is currently waiving its fee for an indefinite
period.

(6) Line of Credit
Each Fund and other affiliated funds participate in a $400 million unsecured
line of credit provided by a syndication of banks under a line of credit
agreement. Borrowings may be made to temporarily finance the repurchase of each
Fund's 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
each Fund for the year ended August 31, 1997, were as follows:

Research International Fund owned the following restricted securities
(consisting of 1.53% of its 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 supplied by a pricing service or brokers or, if not
available, in good faith by or at the direction of the Trustees.

(8) Financial Instruments
The Funds trade financial instruments with off-balance sheet risk in the normal
course of their 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, and futures contracts. The notional or contractual amounts of these
instruments represent the investment the Funds have 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.

Forward foreign currency purchases and sales under master netting arrangements
and closed forward foreign currency exchange contracts for the Special
Opportunities Fund amounted to a net receivable of $175 with Deutschebank at
August 31, 1997.

INDEPENDENT AUDITORS' REPORT

To the Trustees of MFS Series Trust I and Shareholders of MFS Core Growth Fund,
MFS Equity Income Fund, MFS Special Opportunities Fund, MFS Blue Chip Fund, MFS
Convertible Securities Fund, MFS New Discovery Fund, MFS Research International
Fund and MFS Science and Technology Fund:

We have audited the accompanying statements of assets and liabilities of MFS
Core Growth Fund, MFS Equity Income Fund, MFS Special Opportunities Fund, MFS
Blue Chip Fund, MFS Convertible Securities Fund, MFS New Discovery Fund, MFS
Research International Fund and MFS Science and Technology Fund (the Funds)
(eight of the portfolios constituting MFS Series Trust I) including the
schedules of portfolio investments as of August 31, 1997, and the related
statements of operations, the statements of changes in net assets and the
financial highlights for each of the periods indicated herein. These financial
statements and financial highlights are the responsibility of the Funds'
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 audits 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 as of August 31, 1997, 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, MFS Equity Income Fund, MFS Special Opportunities Fund, MFS
Blue Chip Fund, MFS Convertible Securities Fund, MFS New Discovery Fund, MFS
Research International Fund and MFS Science and Technology Fund at August 31,
1997, and the results of their operations, the changes in their net assets, and
the financial highlights for each of the periods indicated herein, in conformity
with generally accepted accounting principles.
