[Photo of A. Keith Brodkin]   MFS Mourns Chairman's Passing
  A. Keith Brodkin            It is with deep regret that we inform you of the
                              death on February 2, 1998, of A. Keith Brodkin,
                              Chairman and Chief Executive Officer of MFS
                              Investment Management(SM). Mr. Brodkin joined MFS
                              in 1970 and made enormous contributions to the
                              organization, including helping to build the
                              firm's investment staff, which will continue to
                              manage all of the MFS investment portfolios. His
                              leadership, friendship, and wise counsel will be
                              sorely missed.

LETTER TO SHAREHOLDERS

Dear Shareholders:

Thanks to a sustained period of relative stability and moderate growth, the
U.S. economy has produced thousands of new jobs, inflation has remained under
control, and the investment climate has -- for the most part -- been
favorable. 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. The rapid
pace of growth seen in the first quarter slowed to an annual rate of 3.3% in
the second quarter and 3.5% in the third. We believe this economic momentum
will carry well into the first quarter of 1998 as a result of lower interest
rates and continuing growth in the money supply. While U.S. economic growth
continues to be impressive, events in the Pacific Rim will somewhat offset
that and, therefore, markets are likely to continue to focus on Federal
Reserve Board activity.

The extreme volatility seen in the U.S. equity market in the fall was, we
believe, the consequence of overvaluations that had been evident for some
months. As a result, the stock market has been vulnerable to some type of
correction and has been impacted in the near term by chaotic market conditions
in the Pacific Rim. In the face of all this, however, the equity

market continues to exhibit surprising strength, much of it the result of
continued gains in corporate earnings, a trend that could be an important
indicator of the market's future direction. Certainly the situation throughout
Asia bears close scrutiny because it appears to be clearly deflationary and
raises the prospect of trade wars developing throughout the area. We are not
convinced that U.S. markets have escaped totally from October's volatility.
Thus, not only is the near-term outlook for profits being adjusted for the
Asian crisis, we also believe equity valuations have risen to a point where a
cautious investment approach seems warranted, with a need for particular
attention to be paid to the effect of Pacific Rim volatility on the earnings
of U.S. companies.

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

Respectfully,

/s/ Jeffrey L. Shames

                                 IN MEMORIAM

                               A. KEITH BRODKIN
                     CHAIRMAN AND CHIEF EXECUTIVE OFFICER
                          MFS INVESTMENT MANAGEMENT

   On February 2, 1998, Keith Brodkin, a friend and leader to everyone at
   MFS, died unexpectedly at age 62. His thoughtful letters to shareholders
   on the markets and economy have been an integral part of MFS shareholder
   reports like this one for many years.

   Keith joined MFS in 1970 as the firm's first fixed-income manager,
   managing the bond portion of MFS(R) Total Return Fund. He went on to
   manage our first pure bond fund, MFS(R) Bond Fund, when it was
   introduced in 1974, and he was considered a pioneer in the art of active
   bond management.

   Keith was named President and Chief Investment Officer of MFS in 1987
   and four years later became Chairman and Chief Executive Officer. During
   his stewardship, MFS has achieved significant growth in total assets
   under management, rising from some $25 billion in 1991 to the over $70
   billion today entrusted to us by three million individual and
   institutional investors worldwide. Under Keith's leadership, MFS has
   carefully but steadily built its domestic and international investment
   capabilities through the introduction of a range of new products and a
   still-growing staff that now numbers over 100 equity and fixed-income
   professionals.

   Throughout his career, Keith was very active in a wide range of
   charitable endeavors. He is survived by his wife and three children.

   His leadership, friendship, and wise counsel will be sorely missed.

A DISCUSSION WITH THE PORTFOLIO MANAGER

[Photo of Paul M. McMahon]
     Paul M. McMahon

For the 12 months ended December 31, 1997, Class A shares of the Fund provided
a total return of 23.28%, Class B shares 22.27%, and Class I shares 24.65%.
These returns, which include the reinvestment of distributions but exclude the
effects of any sales charges, compare to a 33.36% return for the Standard &
Poor's 500 Composite Index (the S&P 500) for the same period. The S&P 500 is a
popular, unmanaged index of common stock total return performance.

Q. WHAT DO YOU SEE AS SOME OF THE REASONS FOR THE FUND'S UNDERPERFORMANCE
   VERSUS ITS BENCHMARK OVER THE PAST YEAR?
A. Relative to growth stock funds in general, the difference was not so great.
   The S&P 500 was by far the best-performing index last year, but the average
   growth fund (as measured by Lipper Analytical Services, Inc., an
   independent firm that reports mutual fund performance) returned 25.30%. The
   Fund was actually doing quite well through October, but it does have a
   fairly cyclical exposure to technology stocks, which hurt performance. I
   believe that, over time, technology is still the place to be, but near term
   there is concern about the impact of the Asian markets on economic growth.
   Japan is the largest component of the Asian market and that's already been
   relatively weak, so the rate of change is not overly significant. It's
   mostly the Asian tiger countries that have seen the tremendous falloff.
   However, the market's perception of the impact was a lot more negative than
   mine, and it hit technology stocks pretty severely. At the same time, the
   Fund's leisure, financial services, and retailing holdings helped
   performance. Also, the miscellaneous holdings, primarily represented by
   Tyco International, helped.

Q. AND WHAT DO YOU SEE FOR THE ASIAN MARKETS GOING INTO 1998?
A. I think it's going to take a while to turn around. These countries need to
   dramatically restructure themselves, as Mexico and Argentina did a few
   years ago. But for political leaders to take strong, negative medicine is
   very difficult, and it takes a while to convince them that it is necessary.
   We're already seeing some countries, like South Korea, taking the right
   steps. Ultimately, I think the other countries will take steps to
   restructure their economies and get them back on the right track.

Q. COULD YOU TALK ABOUT THE FUND'S OVERALL INVESTMENT PHILOSOPHY
   AND STRATEGY?
A. The objective of the Fund is to seek growth of capital. We try to do that
   by focusing on companies in terms of five key factors. The first is good
   earnings growth. Second, we look for quality management. Third, we look for
   positive secular trends, which is why we're staying with technology.
   Fourth, we look for companies that are in good financial shape; that is,
   that have good balance sheets and are generating positive cash flows.
   Fifth, we try to invest in companies during periods of valuation weakness,
   which is another reason why I've been adding to the Fund's technology
   holdings lately, despite the pullback for this sector.

Q. COULD YOU EXPAND A LITTLE BIT ON WHY YOU LIKE TECHNOLOGY
   GOING FORWARD?
A. To begin with, the United States is probably the strongest economic engine
   in the world, in that we have the most competitive society. The big
   investment in technology has been a major reason for that and is critical
   to the success of most U.S. companies, whether it's in pharmaceuticals,
   financial services, or any business that needs to stay competitive, lower
   costs, and increase productivity. As the world becomes a global
   marketplace, other countries, such as Japan and Germany, are going to have
   to step up their spending on technology to stay competitive. So while I
   think we'll still see some moderation in growth for this sector in the
   early part of 1998, after that I think this industry should come back
   fairly strongly.

Q. WHILE TECHNOLOGY IS THE LARGEST SECTOR, THE FUND'S TWO LARGEST HOLDINGS ARE
   TYCO INTERNATIONAL AND HFS, NOW CALLED CENDANT CORP. TELL US ABOUT THESE
   COMPANIES.
A. Tyco has all the qualities that I'm looking for. It has very strong
   earnings growth, about 20% per year. It also has high-quality management, a
   good balance sheet, and positive secular trends in its businesses, such as
   fire safety, which continues to see strong growth both in installation and
   service. I still see good earnings growth for this company, and its
   valuation is still reasonable.

Q. AND WHAT ABOUT CENDANT?
A. The company has gone through a number of consolidations and acquisitions.
   Most recently, it consolidated with CUC International, a consumer
   membership club and Internet shopping company, and with this merger,
   changed its name to Cendant Corp. We believe the company's earnings growth
   should run 25% to 30% per year over the next couple of years, while its
   price-to-earnings ratio is in the mid-20s, so it still has good growth in
   relation to its value. It's a very well-managed company and has significant
   positive cash flow. Finally, we believe its businesses, including
   membership clubs, rental cars, hotels, and real estate, should all do well.
   The company mostly owns franchises, which means minimal investment and a
   lot of positive cash flow. Also, there are several cross-synergies here, by
   which one company generates huge numbers of customer files that can then be
   used to generate leads across a range of businesses.

Q. FINANCIAL SERVICES IS ANOTHER IMPORTANT WEIGHTING FOR THE FUND. COULD YOU
   TALK ABOUT SOME OF THE COMPANIES YOU LIKE IN THIS SECTOR?
A. Financial services companies have benefited from good earnings and lower
   interest rates. One holding we like is the Federal Home Loan Mortgage
   Corp., or Freddie Mac, a secondary home mortgage finance company. Another
   is Finova Corp., a middle-market lender that has performed well.

Q. HAVE YOU SIGNIFICANTLY INCREASED OR DECREASED POSITIONS IN ANY OTHER
   SECTORS THIS YEAR?
A. We did significantly decrease the Fund's industrial goods and services
   position because the earnings outlook seemed to be slowing for a number of
   these companies. At the same time, there was a moderate increase in the
   Fund's retailing holdings, in which we found some companies, such as CVS
   Corp., generating good growth and steady earnings.

Q. EARLIER, YOU SAID THE LEISURE SECTOR HAD DONE WELL. COULD YOU TALK ABOUT
   SOME STOCKS HERE THAT YOU LIKE?
A. In the radio area, companies such as Clear Channel Communications
   and Jacor Communications were very strong performers. There's a lot
   of consolidation activity going on in this industry, and the leading
   players can assemble more stations and create a better product to sell
   to advertisers. In the larger markets, this means a company can present a
   potential advertiser with a package of different radio stations in the same
   market. Also, the robust economy has helped radio stations raise
   advertising rates.

Q. APART FROM TECHNOLOGY, ARE THERE ANY STOCKS OR SECTORS THAT DID NOT PERFORM
   AS WELL AS YOU WOULD HAVE LIKED?
A. Wisconsin Central Corp. was a major disappointment. It missed its earnings
   by a few pennies, and the market drove the stock down. But
   we still think the company has high-quality management and high
   credibility, and we feel they'll be able to turn it around.

Q. WHAT KIND OF INVESTMENT ENVIRONMENT DO YOU ANTICIPATE GOING FORWARD, AND
   HOW MIGHT THIS AFFECT SOME OF YOUR INVESTMENTS IN THE FUND?
A. I think we're still going to see decent economic growth, although it could
   slow in the first half of 1998. But that means interest rates should come
   down, which should support current price-to-earnings ratios. However, more
   moderate growth in the first half could lead to some earnings
   disappointments, so the key is to focus on companies that can deliver the
   earnings.

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 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 I shares
("I"), which became available on January 2, 1997, have no sales charge or Rule
12b-1 fees and are only available to certain institutional investors.

B results include the performance and the operating expenses (e.g., Rule 12b-1
fees) of A for periods prior to the inception of B. Because operating expenses
of A are lower than those of B, B performance generally would have been lower
than A performance. The A performance included within the B SEC performance
has been adjusted to reflect the CDSC generally applicable to B 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.

NOTES TO FINANCIAL STATEMENTS

(1) Business and Organization
MFS Growth Opportunities Fund (the Fund) is organized as a Massachusetts
business trust and is registered under the Investment Company Act of 1940,
as amended, as a diversified, 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. Futures contracts, options, and options on futures
contracts listed on commodities exchanges are reported at market value using
closing settlement 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 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 results from fluctuations in foreign currency
exchange rates is not separately disclosed.

Futures Contracts - The fund may enter into futures contracts for the delayed
delivery of securities currency, or contracts based on financial indices at a
fixed price on a future date. In entering such contracts, the Fund is required
to deposit either in cash or securities an amount equal to a certain
percentage of the contract amount. Subsequent payments are made or received by
the Fund each day, depending on the daily fluctuations in the value of the
underlying security, and are recorded for financial statement purposes as
unrealized gains or losses by the Fund. The Fund's investment in futures
contracts is designed to hedge against anticipated future changes in
securities prices. Should securities prices move unexpectedly, the Fund may
not achieve the anticipated benefits of the futures contracts and may
realize a loss.

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 will enter
into contracts for hedging purposes as well as for nonhedging 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. 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 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 average daily 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. The 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 the 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.

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 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 December 31, 1997, $1,774,006 was
reclassified to accumulated net realized gain on investments and foreign
currency transactions from accumulated net investment loss due to differences
between book and tax accounting for currency transactions and net investment
losses. This change had no effect on the net assets or the net asset value per
share.

Multiple Classes of Shares of Beneficial Interest - The Fund offers multiple
classes of shares. The classes of shares differ in their respective
distribution and service fees. All shareholders bear the common expenses of
the Fund 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 - 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 $200 million of average net assets                                 0.50%
Average net assets in excess of $200 million                             0.40%

Administrator - Effective March 1, 1997, 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 percentage 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%

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 of the 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 its independent Trustees and Mr. Bailey.
Included in Trustees' compensation is a net periodic pension expense of
$16,337 for the year ended December 31, 1997.

Distributor - MFD, a wholly owned subsidiary of MFS, as distributor, received
$556,133 for the year ended December 31, 1997, 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 and Class B 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
to each securities dealer that enters into a sales agreement with MFD of up to
0.25% per annum (reduced to 0.15% per annum for assets sold prior to March 1,
1991) of the 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 0.10% per annum of the 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 the Fund. MFD retains the service fee for
accounts not attributable to a securities dealer which amounted to $724,212
for the year ended December 31, 1997. Payment of the 0.10% per annum Class A
distribution fee will commence on such date as the Trustees of the Fund may
determine. Fees incurred under the distribution plan during the year ended
December 31, 1997, were 0.18% 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 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 shares. The service fee is intended
to be additional consideration for services rendered by the dealer with respect
to Class B shares. MFD retains the service fee for accounts not attributable to
a securities dealer, which amounted to $13,277 for Class B shares for the year
ended December 31, 1997. Fees incurred under the distribution plan during the
year ended December 31, 1997, were 1.00% of average daily net assets
attributable to Class B shares on an annualized basis.

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. 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 December 31, 1997, were
$4,861 and $23,865 for Class A and Class B
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 effective annual
rate of 0.13%.

(4) Portfolio Securities
Purchases and sales of investments, other than U.S. government securities and
short-term obligations, aggregated $539,485,455 and $615,515,213,
respectively.

The cost and unrealized appreciation or depreciation in value of the
investments owned by the Fund, as computed on a federal income tax basis, are
as follows:

Aggregate cost                                                   $703,752,781

Gross unrealized appreciation                                    $308,555,228
Gross unrealized depreciation                                     (35,263,945)
                                                                 ------------
    Net unrealized appreciation                                  $273,291,283
                                                                 ============

INDEPENDENT AUDITORS' REPORT

To the Trustees and Shareholders of MFS Growth Opportunities Fund:

We have audited the accompanying statement of assets and liabilities,
including the portfolio of investments, of MFS Growth Opportunities Fund as of
December 31, 1997, the related statement of operations for the year then
ended, the statement of changes in net assets for the years ended December 31,
1997 and 1996, and the financial highlights for each of the years in the ten-
year period ended December 31, 1997. 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. Our procedures included confirmation of the
securities owned at December 31, 1997, 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 and financial highlights present
fairly, in all material respects, the financial position of MFS Growth
Opportunities Fund at December 31, 1997, the results of its operations, the
changes in its net assets, and its financial highlights for the respective
stated periods in conformity with generally accepted accounting principles.
