LETTER TO SHAREHOLDERS
Dear Shareholders:
We would like to welcome you as shareholders of MFS Institutional Research Fund,
which commenced operations on May 21, 1996. The Fund seeks to provide long-term
growth of capital and future income by investing, under normal market
conditions, at least 65% of its total assets in equity securities of companies
we believe possess better-than-average prospects for long-term growth. From
inception through June 30, 1996, the Fund provided a total return of -2.20%. A
discussion of the Fund's investments may be found in the Portfolio Performance
and Strategy section of this letter.
Economic Environment
Real (inflation-adjusted) economic growth in the first quarter of 1996 was 2.3%
on an annualized basis, and it appears that second-quarter growth could be even
stronger. Thus, real growth in gross domestic product has started the year at a
rate exceeding our expectations. While we continue to believe that growth from
quarter to quarter will be uneven, it is now our expectation that growth for all
of 1996 could exceed 2.5%. Although individual consumers appear to be carrying
an excessive debt load, the consumer sector itself, which represents two-thirds
of the economy, continues to be impressive as the auto and housing markets
remain resilient. Consumer spending has also been positively impacted by
widespread job growth. At the same time, however, the economies of Europe and
Japan continue to be in the doldrums, weakening U.S. export markets while
subduing the capital spending plans of American corporations. Finally, due to
the pickup in economic activity and increasing job growth, it appears that
inflation may accelerate slightly this year, and the Federal Reserve Board is
expected to continue its diligent anti-inflationary stance.
While we do not expect the U.S. stock market to match the extraordinary
performance of 1995, we continue to be positive about the equity market this
year. Although we believe the equity market represents fair value at current
levels, the expected slowdown in the growth of corporate earnings and the
increases in interest rates experienced so far this year raise near-term
concerns. Further increases in interest rates, and an acceleration of inflation
coupled with an additional slowdown in corporate earnings growth, could have a
negative effect on the stock market. However, to the extent that some earnings
disappointments are taken as a sign that the economy is not overheating, this
may prove beneficial for the longer-term health of the equity market. We
continue to believe that many of the technology-driven productivity gains that
U.S. companies have made in recent years will continue to enhance corporate
America's competitiveness and profitability. Therefore, while we have some
near-term concerns, we remain quite constructive on the long-term viability of
the equity market.
Portfolio Performance and Strategy
The Fund is diversified across 118 companies within 13 different sectors of the
economy, and it is currently overweighted in technology, leisure, industrial
goods and services, and retailing. We believe select companies within each of
these sectors offer strong earnings potential given the current economic
environment. Within the technology sector, companies such as Microsoft, Sun
Microsystems, Compuware, and Glenayre Technologies have contributed to the
Fund's performance, while within the leisure sector the hotel industry continues
to be an attractive area. HFS, Inc., both through recent acquisitions and
existing business growth, has demonstrated superior earnings potential and
remains one of the Fund's top holdings.
The Fund is currently underweighted in utilities and communications, mainly
due to an unfavorable economic outlook for some industries within this sector.
The utility industry, for example, is currently being impacted by increased
competition and lower growth prospects.
Respectfully,
/s/ A. Keith Brodkin /s/ Kevin R. Parke
A. Keith Brodkin Kevin R. Parke
Chairman and President Director of Research
July 10, 1996
A Committee of MFS Institutional Research Analysts is responsible for the
day-to-day management of the Fund under the general supervision of Mr. Parke.
OBJECTIVE AND POLICIES
The Fund's investment objective is to provide long-term growth of capital and
future income. The Fund invests, under normal market conditions, at least 65% of
its total assets in equity securities of companies believed to possess
better-than-average prospects for long-term growth.
TAX FORM SUMMARY
In January 1997, shareholders will be mailed a Tax Form Summary reporting the
federal tax status of all distributions paid during the calendar year 1996.

NOTES TO FINANCIAL STATEMENTS
(1) Business and Organization
MFS Institutional Research Fund (the Fund) is a diversified series of MFS
Institutional Trust (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 reported amounts of revenues and expenses during the 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 valued at last sale prices. Unlisted
equity securities or listed equity securities for which last sale prices are not
available are valued at last quoted bid prices. Debt securities (other than
short-term obligations which mature in 60 days or less), including listed
issues, 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. Short-term obligations, which mature
in 60 days or less, are valued at amortized cost, which approximates market
value. Non-U.S. dollar denominated short-term obligations are valued at
amortized cost as calculated in the base currency and translated into U.S.
dollars at the closing daily exchange rate. 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.
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
operations of the Fund.
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 are amortized or accreted for financial statement and
tax reporting purposes as required by federal income tax regulations. Dividend
income is recorded on the ex-dividend date for dividends received in cash.
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.
Tax Matters and Distributions - The Fund's policy is to comply with the
provisions of the Internal Revenue Code (the Code) applicable to regulated
investment companies and to distribute to shareholders all of its net taxable
income, including any net realized gain on investments. At June 30, 1996, the
Fund elected not to be taxed as a regulated investment company. 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. Foreign taxes
have been provided for on interest and dividend income earned on foreign
investments in accordance with the applicable country's tax rates and to the
extent unrecoverable are recorded as a reduction of investment income.
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 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.
(3) Transactions with Affiliates
Investment Adviser - The Fund has an investment advisory agreement with
Massachusetts Financial Services Company (MFS) to provide overall investment
advisory and administrative services, and general office facilities. The
management fee is computed daily and paid monthly at an effective annual rate of
0.60% of average daily net assets. The investment adviser did not impose a
portion of its fee, which is reflected as a reduction of expenses on the
Statement of Operations.
MFS has voluntarily agreed to pay the Fund's operating expenses exclusive of
management fees such that the Fund's aggregate expenses do not exceed 0.65% of
its average daily net assets.
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 and MFS Service Center, Inc. (MFSC).
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 average daily net assets of the Fund at an effective annual rate
of up to 0.0075%.
(4) Portfolio Securities
Purchases and sales of investments, other than purchased option transactions and
short-term obligations, aggregated $24,712,259 and $1,402,314, 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 $23,327,992

(6) Line of Credit
The Fund entered into an agreement which enables it to participate with other
funds managed by MFS in an unsecured line of credit with a bank which permits
borrowings up to $350 million, collectively. 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 period ended June 30,
1996 was $5.
(7) Restricted Securities
The Fund may invest not more than 15% of its net assets in securities which are
subject to legal or contractual restrictions on resale. At June 30, 1996, the
Fund owned the following restricted security (constituting 0.5% of net assets)
which may not be publicly sold without registration under the Securities Act of
1933. The Fund does not have the right to demand that such security be
registered. The value of this security 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.

INDEPENDENT AUDITORS' REPORT
To the Trustees of MFS Institutional Trust and Shareholders of MFS Institutional
Research Fund:
We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of MFS Institutional Research Fund (one of the
series comprising MFS Institutional Trust) as of June 30, 1996, and the related
statement of operations, the statement of changes in net assets and the
financial highlights for the period from May 21, 1996, commencement of
operations, to June 30, 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 audit.
We conducted our audit 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 June 30, 1996 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 audit provides 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 Institutional
Research Fund at June 30, 1996, the results of its operations, the changes in
its net assets, and its financial highlights for the period from May 21, 1996,
commencement of operations, to June 30, 1996 in conformity with generally
accepted accounting principles.
