LETTER FROM THE CEO

[Photo of Robert J. Manning]

Dear Shareholders:
The story is as old as the tortoise and the hare, but we believe it is still
relevant today -- "slow and steady" is the way to go when it comes to
investing. While financial markets will naturally ebb and flow over time,
investors who remain committed to a long-term investment strategy are more
likely to achieve their goals than those who consistently chase short-term
performance.

The first half of 2006 brought a high degree of fluctuation in markets around
the globe as varying economic factors pulled markets in opposite directions.
The global economy, for example, continued to grow at its fastest pace in
three decades -- spurred by increased international trade, good job growth,
and wage increases. At the same time, central banks around the world raised
interest rates in sync in a collaborative attempt to curb inflation. While
this was a positive development in some regions, in other cases, economic and
market gains were tempered.

What does all of this mean to you as an investor? If you're focused on the
long term, these global developments become part of a longer cycle instead of
one-time events that can have a significant impact on your portfolio.

At MFS(R), our investment management process -- honed over 80 years --
combines a unique teamwork approach with an unwavering focus on helping you
realize your long-term financial goals. We believe in a three-pronged
investment strategy:

  o ALLOCATE holdings across the major asset classes -- including stocks, bonds,
    and cash.

  o DIVERSIFY within each class to take advantage of different market segments
    and investing styles.

  o REBALANCE assets regularly to maintain a desired asset allocation.

Of course, these strategies cannot guarantee a profit or protect against a
loss. Investing and planning for the long term requires diligence and
patience, two traits that in our experience are essential to capitalizing on
the many opportunities the financial markets can offer -- through both up and
down economic cycles.

    Respectfully,

/s/ Robert J. Manning

              Average Credit Quality of Rated
              Securities (short-term) (a)                  A-1
              ------------------------------------------------

(a) The average credit quality of rated securities is based upon a market
    weighted average of portfolio holdings that are rated by public rating
    agencies.
(d) Duration is a measure of how much a bond's price is likely to fluctuate with
    general changes in interest rates, e.g., if rates rise 1.00%, a bond with a
    5-year duration is likely to lose about 5.00% of its value.
(i) For purposes of this graphical presentation, the bond component includes
    both accrued interest amounts and the equivalent exposure from any
    derivative holdings, if applicable.
(m) The average maturity shown is calculated using the final stated maturity on
    the portfolio's holdings without taking into account any holdings which have
    been pre-refunded or pre-paid to an earlier date or which have a mandatory
    put date prior to the stated maturity. The average life shown takes into
    account these earlier dates.
(r) Each security is assigned a rating from Moody's Investors Service. If not
    rated by Moody's, the rating will be that assigned by Standard & Poor's.
    Likewise, if not assigned a rating by Standard & Poor's, it will be based on
    the rating assigned by Fitch, Inc. For those portfolios that hold a security
    which is not rated by any of the three agencies, the security is considered
    Not Rated. Holdings in U.S. Treasuries and government agency mortgage-backed
    securities, if any, are included in a "AAA"-rating category. Percentages are
    based on the total market value of investments as of 7/31/06.

Percentages are based on net assets as of 7/31/06, unless otherwise noted.

The portfolio is actively managed, and current holdings may be different.


EXPENSE TABLE

Fund expenses borne by the shareholders during the period,
February 1, 2006 through July 31, 2006.

As a shareholder of the fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on certain purchase or redemption
payments and redemption fees on certain exchanges and redemptions, and (2)
ongoing costs, including management fees; distribution and service (12b-1)
fees; and other fund expenses. This example is intended to help you understand
your ongoing costs (in dollars) of investing in the fund and to compare these
costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning
of the period and held for the entire period February 1, 2006 through
July 31, 2006.

ACTUAL EXPENSES

The first line for each share class in the following table provides
information about actual account values and actual expenses. You may use the
information in this line, together with the amount you invested, to estimate
the expenses that you paid over the period. Simply divide your account value
by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then
multiply the result by the number in the first line under the heading entitled
"Expenses Paid During Period" to estimate the expenses you paid on your
account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line for each share class in the following table provides
information about hypothetical account values and hypothetical expenses based
on the fund's actual expense ratio and an assumed rate of return of 5% per
year before expenses, which is not the fund's actual return. The hypothetical
account values and expenses may not be used to estimate the actual ending
account balance or expenses you paid for the period. You may use this
information to compare the ongoing costs of investing in the fund and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or redemption fees. Therefore, the second line for each share
class in the table is useful in comparing ongoing costs only, and will not
help you determine the relative total costs of owning different funds. In
addition, if these transactional costs were included, your costs would have
been higher.

(h) 5% class return per year before expenses.
(p) Expenses paid is equal to each class' annualized expense ratio, as shown
    above, multiplied by the average account value over the period, multiplied
    by the number of days in the period, divided by the number of days in the
    year. Expenses paid do not include any applicable sales charges (loads) or
    redemption fees. If these transaction costs had been included, your costs
    would have been higher.

At July 31, 2006 the fund had sufficient cash and/or securities to cover any commitments under
these contracts.

(a) Security exempt from registration under Rule 144A of the Securities Act of 1933. These
    securities may be sold in transactions exempt from registration, normally to qualified
    institutional buyers. At period end, the aggregate value of these securities was
    $135,681,250, representing 21.6% of net assets.
(e) The rate shown represents a current effective yield.
(g) The rate shown represents a weighted average coupon rate on settled positions at period end.
(i) Interest only security for which the fund receives interest on notional principal (Par
    amount). Par amount shown is the notional principal and does not reflect the cost of the
    security.
(k) As of July 31, 2006, the fund held securities fair valued in accordance with the policies
    adopted by the Board of Trustees, aggregating $540,249,010 and 87.52% of market value. An
    independent pricing service provided an evaluated bid for 84.52% of the market value.
(n) Non-income producing security.
(p) Payment-in-kind security.
(r) Remaining maturities of floating rate loans may be less than stated maturities shown as a
    result of contractual or optional prepayments by the borrower. Such prepayments cannot be
    predicted with certainty. These loans may be subject to restrictions on resale. Floating rate
    loans generally have rates of interest which are determined periodically by reference to a
    base lending rate plus a premium.
(y) The rate shown represents an annualized yield at time of purchase.
(z) Restricted securities are not registered under the Securities Act of 1933 and are subject to
    legal restrictions on resale. These securities generally may be resold in transactions exempt
    from registration or to the public if the securities are subsequently registered. Disposal of
    these securities may involve time-consuming negotiations and prompt sale at an acceptable

the past 5 fiscal years. Certain information reflects financial results for a single fund share. The total returns in the table
represent the rate by which an investor would have earned (or lost) on an investment in the fund share class (assuming
reinvestment of all distributions) held for the entire period.

NOTES TO FINANCIAL STATEMENTS
(unaudited)

(1) BUSINESS AND ORGANIZATION

MFS High Yield Opportunities Fund (the fund) is a series of MFS Series Trust
III (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 U.S.
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. The
fund can 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 fund can invest in
foreign securities. Investments in foreign securities are vulnerable to the
effects of changes in the relative values of the local currency and the U.S.
dollar and to the effects of changes in each country's legal, political, and
economic environment. The markets of emerging markets countries are generally
more volatile than the markets of developed countries with more mature
economies. All of the risks of investing in foreign securities previously
described are heightened when investing in emerging markets countries.

INVESTMENT VALUATIONS - Equity securities, including restricted equity
securities, are generally valued at the last sale or official closing price as
reported by an independent pricing service on the market or exchange on which
they are primarily traded. For securities for which there were no sales
reported that day, equity securities are generally valued at the last quoted
daily bid quotation as reported by an independent pricing service on the
market or exchange on which they are primarily traded. Debt instruments (other
than short-term instruments), including restricted debt instruments, are
generally valued at an evaluated or composite bid as reported by an
independent pricing service. Values of debt instruments obtained from pricing
services can utilize both dealer-supplied valuations and electronic data
processing techniques, which take into account 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. Short-
term instruments with a maturity at issuance of 60 days or less may be valued
at amortized cost, which approximates market value. Forward foreign currency
contracts are generally valued at the mean of bid and asked prices for the
time period interpolated from rates reported by an independent pricing service
for proximate time periods. Swaps are generally valued at a broker-dealer bid
quotation. Securities and other assets generally valued on the basis of
information from an independent pricing service may also be valued at a
broker-dealer bid quotation. The values of foreign securities and other assets
and liabilities expressed in foreign currencies are converted to U.S. dollars
using the mean of bid and asked prices for rates reported by an independent
pricing service. The Board of Trustees has delegated primary responsibility
for determining or causing to be determined the value of the fund's
investments (including any fair valuation) to the adviser pursuant to
valuation policies and procedures approved by the Board. If the adviser
determines that reliable market quotations are not readily available,
investments are valued at fair value as determined in good faith by the
adviser in accordance with such procedures under the oversight of the Board of
Trustees. Under the fund's valuation policies and procedures, market
quotations are not considered to be readily available for many types of debt
instruments. These investments are generally valued at fair value based on
information from independent pricing services. The adviser may rely on
independent pricing services or other information (such as the correlation
with price movements of similar securities in the same or other markets; the
type, cost and investment characteristics of the security; the business and
financial condition of the issuer; and trading and other market data) to
assist in determining whether to fair value and at what value to fair value an
investment. The value of an investment for purposes of calculating the fund's
net asset value can differ depending on the source and method used to
determine value. When fair valuation is used, the value of investments used to
determine the fund's net asset value may differ from quoted or published
prices for the same investments. In addition, investments may be valued at
fair value if the adviser determines that an investment's value has been
materially affected by events occurring after the close of the exchange or
market on which the investment is principally traded (such as foreign exchange
or market) and prior to the determination of the fund's net asset value, or
after the halting of trading of a specific security where trading does not
resume prior to the close of the exchange or market on which the security is
principally traded. Events that occur on a frequent basis after foreign
markets close (such as developments in foreign markets and significant
movements in the U.S. markets) and prior to the determination of the fund's
net asset value may be deemed to have a material affect on the value of
securities traded in foreign markets. Accordingly, the fund's foreign equity
securities may often be valued at fair value.

REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with
institutions that the fund's investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. The fund requires
that the securities collateral in a repurchase transaction be transferred to
the custodian in a manner sufficient to enable the fund to obtain those
securities in the event of a default under the repurchase agreement. The fund
monitors, on a daily basis, the value of the collateral to ensure that its
value, including accrued interest, is greater than amounts owed to the fund
under each such repurchase agreement. The fund, along with other affiliated
entities of Massachusetts Financial Services Company (MFS), may utilize a joint
trading account for the purpose of entering into one or more repurchase
agreements.

FOREIGN CURRENCY TRANSLATION - 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.

DERIVATIVE RISK - The fund may invest in derivatives for hedging or non-
hedging purposes. While hedging can reduce or eliminate losses, it can also
reduce or eliminate gains. When the fund uses derivatives as an investment to
gain market exposure, or for hedging purposes, gains and losses from
derivative instruments may be substantially greater than the derivative's
original cost. Derivative instruments include forward foreign currency
exchange contracts and swap agreements.

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 the contract. The fund may enter into forward foreign currency
exchange contracts for hedging purposes as well as for non-hedging purposes.
For hedging purposes, the fund may enter into contracts to deliver or receive
foreign currency it will receive from or require for its normal investment
activities. The fund may also use contracts in a manner intended to protect
foreign currency denominated securities from declines in value due to
unfavorable exchange rate movements. For non-hedging purposes, the fund may
enter into contracts with the intent of changing the relative exposure of the
fund's portfolio of securities to different currencies to take advantage of
anticipated changes. The forward foreign currency exchange contracts are
adjusted by the daily exchange rate of the underlying currency and any gains
or losses are recorded as unrealized until the contract settlement date. On
contract settlement date, the gains or losses are recorded as realized gains
or losses on foreign currency transactions.

SWAP AGREEMENTS - The fund may enter into swap agreements. A swap is an
exchange of cash payments between the fund and another party. Net cash
payments are exchanged at specified intervals and are recorded as a realized
gain or loss in the Statement of Operations. The value of the swap is adjusted
daily and the change in value is recorded as unrealized appreciation or
depreciation in the Statement of Operations. Risks may arise upon entering
into these agreements from the potential inability of counterparties to meet
the terms of their contract and from unanticipated changes in the value of the
financial index on which the swap agreement is based.

CREDIT DEFAULT SWAPS - The fund may enter into credit default swaps to limit
or to reduce risk exposure of the fund to credit events such as bankruptcy,
failure to pay, or a restructuring of corporate and sovereign issuers. The
fund may also use credit default swaps to create direct or synthetic short or
long exposure to domestic or foreign corporate debt securities or certain
sovereign debt securities to which the fund is not otherwise exposed. In a
credit default swap, one party makes a stream of payments to another party in
exchange for the right to receive a specified return in the event of a default
by a third party, such as a corporate issuer or foreign issuer on its
obligation.

LOANS AND OTHER DIRECT DEBT INSTRUMENTS - The fund may invest in loans and
loan participations or other receivables. These investments may include
standby financing commitments, including revolving credit facilities, which
obligate the fund to supply additional cash to the borrower on demand. Loan
participations involve a risk of insolvency of the lending bank or other
financial intermediary.

SHORT TERM FEES - For purchases made on or after July 1, 2004 and before April
1, 2005, the fund charged a 2% redemption fee (which was retained by the fund)
on proceeds from Class A, Class B, Class C, and Class I shares redeemed or
exchanged within 30 calendar days following their acquisition (either by
purchase or exchange). Effective April 1, 2005, the fund charges a 1%
redemption fee on proceeds from Class A, Class B, Class C, and Class I shares
redeemed or exchanged within 30 calendar days following their acquisition. The
fund may change the redemption fee period in the future, including in
connection with Securities and Exchange Commission rule developments. See the
fund's prospectus for details. Any redemption fees are accounted for as an
addition to paid-in capital.

INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on
the trade date. Interest income is recorded on the accrual basis. All premium
and discount is amortized or accreted for financial statement purposes in
accordance with U.S. generally accepted accounting principles. All discount is
accreted for tax reporting purposes as required by federal income tax
regulations. The fund earns certain fees in connection with its floating rate
loan purchasing activities. These fees are in addition to interest payments
earned and may include amendment fees, commitment fees, consent fees, and
prepayment fees. These fees are recorded on an accrual basis as income in the
accompanying financial statements. Dividends received in cash are recorded on
the ex-dividend date. Certain dividends from foreign securities will be
recorded when the fund is informed of the dividend if such information is
obtained subsequent to 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 fund may receive proceeds from litigation settlements involving its
portfolio holdings. Any proceeds received are reflected in realized gain/loss
in the Statement of Operations, or in unrealized gain/loss if the security is
still held by the fund. 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 made directly
to the security issuer, 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 - The fund's custody fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by
the fund. This amount, for the six months ended July 31, 2006, is shown as a
reduction of total expenses on the Statement of Operations.

TAX MATTERS AND DISTRIBUTIONS - The fund intends to qualify as a regulated
investment company, as defined under Subchapter M of the Internal Revenue
Code, and to distribute all of its taxable income, including realized capital
gains. Accordingly, no provision for federal income tax is required in the
financial statements. Foreign taxes, if any, have been accrued by the fund in
the accompanying financial statements.

Distributions to shareholders are recorded on the ex-dividend date. Income and
capital gain distributions are determined in accordance with income tax
regulations, which may differ from generally accepted accounting principles.
Certain capital accounts in the financial statements are periodically adjusted
for permanent differences in order to reflect their tax character. These
adjustments have no impact on net assets or net asset value per share.
Temporary differences which arise from recognizing certain items of income,
expense, gain or loss in different periods for financial statement and tax
purposes will reverse at some time in the future. Distributions in excess of
net investment income or net realized gains are temporary overdistributions
for financial statement purposes resulting from differences in the recognition
or classification of income or distributions for financial statement and
tax purposes.

Book/tax differences primarily relate to amortization and accretion of debt
securities, defaulted bonds, foreign currency transactions, and treating a
portion of the proceeds from redemptions as a distribution for tax purposes.

The tax character of distributions made during the current period will be
determined at fiscal year end. The tax character of distributions declared to
shareholders is as follows:

                                                         1/31/06        1/31/05
Ordinary income (including any short-term
  capital gains)                                     $45,471,541    $36,308,924
Long-term capital gain                                 1,045,398      1,736,139

Total distributions                                  $46,516,939    $38,045,063

The federal tax cost and the tax basis components of distributable earnings
were as follows:

          AS OF 7/31/06
          Cost of investments                          $620,595,404

          Gross depreciation                            (14,709,615)
          ---------------------------------------------------------
          Net unrealized appreciation (depreciation)    $(3,315,965)

          AS OF 1/31/06
          Undistributed ordinary income                  $3,624,169
          Post-October capital loss deferral             (4,422,799)
          Other temporary differences                    (3,716,274)
          Net unrealized appreciation (depreciation)      7,385,556

The aggregate cost above includes prior fiscal year end tax adjustments.

In June 2006, FASB Interpretation No. 48, Accounting for Uncertainty in Income
Taxes (the "Interpretation") was issued, and is effective for fiscal years
beginning after December 15, 2006 and is to be applied to all open tax years
as of the effective date. This Interpretation prescribes a minimum threshold
for financial statement recognition of the benefit of a tax position taken or
expected to be taken in a tax return, and requires certain expanded
disclosures. Management has recently begun to evaluate the application of
the Interpretation to the fund, and has not at this time determined the
impact, if any, resulting from the adoption of this Interpretation on the
fund's financial statements.

MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple
classes of shares, which differ in their respective distribution and service
fees. All shareholders bear the common expenses of the fund based on the value
of settled shares outstanding of each class, without distinction between share
classes. Dividends are declared separately for each class. Differences in per
share dividend rates are generally due to differences in separate class
expenses. Class B shares will convert to Class A shares approximately eight
years after purchase.

(3) TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISER - The fund has an investment advisory agreement with
Massachusetts Financial Services Company (MFS) to provide overall investment
advisory and administrative services, and general office facilities. The
management fee is computed daily and paid monthly at an annual rate of 0.65%
of the fund's average daily net assets. As part of a settlement agreement with
the New York Attorney General concerning market timing and related matters,
MFS has agreed to reduce the management fee to 0.50% of the fund's average
daily net assets for the period March 1, 2004 through February 28, 2009.
For the six months ended July 31, 2006, this waiver amounted to $462,816 and
is reflected as a reduction of total expenses in the Statement of Operations.

The management fee incurred for the six months ended July 31, 2006 was
equivalent to an annual effective rate of 0.50% of the fund's average daily
net assets.

The investment adviser has agreed in writing to pay all of the fund's operating
expenses, exclusive of management, distribution and service and certain other
fees and expenses. This written agreement will continue through May 31, 2007.
For the six months ended July 31, 2006, this reduction amounted to $847,571 and
is reflected as a reduction of total expenses in the Statement of Operations.

DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of
MFS, as distributor, received $72,675 for the six months ended July 31, 2006,
as its portion of the initial sales charge on sales of Class A shares of the
fund.

The Board of Trustees has adopted a distribution plan for certain class shares
pursuant to Rule 12b-1 of the Investment Company Act of 1940.

The fund's distribution plan provides that the fund will pay MFD for services
provided by MFD and financial intermediaries in connection with the
distribution and servicing of certain share classes. One component of the plan
is a distribution fee paid to MFD and another component of the plan is a
service fee paid to MFD. MFD may subsequently pay all, or a portion, of the
distribution and/or service fees to financial intermediaries.

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 of purchase.
Class B shares are subject to a contingent deferred sales charge in the event
of a shareholder redemption within six years of purchase. All contingent
deferred sales charges are paid to MFD and during the six months ended July
31, 2006, were as follows:

                                                          AMOUNT

              Class A                                       $187
              Class B                                   $145,363
              Class C                                     $8,926

SHAREHOLDER SERVICING AGENT - The fund pays a portion of shareholder servicing
costs to MFS Service Center, Inc. (MFSC), a wholly-owned subsidiary of MFS.
MFSC receives a fee from the fund, for its services as shareholder servicing
agent, set periodically under the supervision of the fund's Board of Trustees.
For the six months ended July 31, 2006, the fee was $306,457, which equated to
0.0993% annually of the fund's average daily net assets. MFSC also receives
payment from the fund for out-of-pocket and sub-accounting expenses paid by
MFSC on behalf of the fund. For the six months ended July 31, 2006, these
costs amounted to $78,190.

ADMINISTRATOR - MFS provides certain financial, legal, shareholder
communications, compliance, and other administrative services to certain funds
for which MFS acts as investment adviser. Under an administrative services
agreement, the funds may partially reimburse MFS the costs incurred to provide
these services, subject to review and approval by the Board of Trustees. Each
fund is charged a fixed amount plus a fee based on calendar year average net
assets. From July 1, 2005 through March 31, 2006, the fund's annual fixed
amount was $10,000. Effective April 1, 2006, the fund's annual fixed amount is
$17,500. The administrative services fee incurred for the six months ended
July 31, 2006 was equivalent to an annual effective rate of 0.0178% of the
fund's average daily net assets.

TRUSTEES' AND OFFICERS' COMPENSATION - The fund pays compensation to
Independent Trustees in the form of a retainer, attendance fees, and additional
compensation to Board and Committee chairpersons. The fund does not pay
compensation directly to Trustees or officers of the fund who are also officers
of the investment adviser, 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, MFD, and MFSC. The fund has an unfunded, retirement benefit
deferral plan for certain Independent Trustees which resulted in an expense of
$256. This amount is included in Independent Trustees' compensation for the six
months ended July 31, 2006. The deferred liability for retirement benefits
payable to certain Trustees amounted to $8,193 at July 31, 2006, and is
included in payable for Independent Trustees' compensation.

OTHER - This fund and certain other MFS funds (the funds) have entered into a
services agreement (the Agreement) which provides for payment of fees by the
funds to Tarantino LLC in return for the provision of services of an
Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an
officer of the funds and the sole member of Tarantino LLC. The funds can
terminate the Agreement with Tarantino LLC at any time under the terms of the
Agreement. For the six months ended July 31, 2006, the fee paid to Tarantino
LLC was $2,427. MFS has agreed to reimburse the fund for a portion of the
payments made by the funds to Tarantino LLC in the amount of $1,829, which is
shown as a reduction of total expenses in the Statement of Operations.
Additionally, MFS has agreed to bear all expenses associated with office
space, other administrative support, and supplies provided to the ICCO.

(6) LINE OF CREDIT

The fund and other affiliated funds participate in a $1 billion unsecured
committed line of credit provided by a syndication of banks under a credit
agreement. In addition, the fund and other affiliated funds have established
uncommitted borrowing arrangements with certain banks. Borrowings may be made
for temporary financing needs. Interest is charged to each fund, based on its
borrowings, generally at a rate equal to the Federal Reserve funds rate plus
0.35%. In addition, a commitment fee, based on the average daily, unused
portion of the committed line of credit, is allocated among the participating
funds at the end of each calendar quarter. For the six months ended
July 31, 2006, the fund's commitment fee and interest expense were $1,958 and
$0, respectively, and are included in miscellaneous expense on the Statement
of Operations.


BOARD REVIEW OF INVESTMENT
ADVISORY AGREEMENT

The Investment Company Act of 1940 requires that both the full Board of
Trustees and a majority of the non-interested ("independent") Trustees, voting
separately, annually approve the continuation of the Fund's investment
advisory agreement with MFS. The Trustees consider matters bearing on the Fund
and its advisory arrangements at their meetings throughout the year, including
a review of performance data at each regular meeting. In addition, the
independent Trustees met several times over the course of three months
beginning in May and ending in July, 2006 ("contract review meetings") for the
specific purpose of considering whether to approve the continuation of the
investment advisory agreement for the Fund and the other investment companies
that the Board oversees (the "MFS Funds"). The independent Trustees were
assisted in their evaluation of the Fund's investment advisory agreement by
independent legal counsel, from whom they received separate legal advice and
with whom they met separately from MFS during various contract review
meetings. The independent Trustees were also assisted in this process by the
MFS Funds' Independent Chief Compliance Officer, a full-time senior officer
appointed by and reporting to the independent Trustees.

In connection with their deliberations regarding the continuation of the
investment advisory agreement, the Trustees, including the independent
Trustees, considered such information and factors as they believed, in light
of the legal advice furnished to them and their own business judgment, to be
relevant. The investment advisory agreement for the Fund was considered
separately, although the Trustees also took into account the common interests
of all MFS Funds in their review. As described below, the Trustees considered
the nature, quality, and extent of the various investment advisory,
administrative, and shareholder services performed by MFS under the existing
investment advisory agreement and other arrangements with the Fund.

In connection with their contract review meetings, the Trustees received and
relied upon materials which included, among other items: (i) information
provided by Lipper Inc. on the investment performance of the Fund for various
time periods ended December 31, 2005 and the investment performance of a group
of funds with substantially similar investment classifications/objectives (the
"Lipper performance universe"), as well as the investment performance of a
group of funds identified by objective criteria suggested by MFS ("MFS peer
funds"), (ii) information provided by Lipper Inc. on the Fund's advisory fees
and other expenses and the advisory fees and other expenses of comparable
funds identified by Lipper (the "Lipper expense group"), as well as the
advisory fees and other expenses of MFS peer funds, (iii) information provided
by MFS on the advisory fees of comparable portfolios of other clients of MFS,
including institutional separate accounts and other clients, (iv) information
as to whether and to what extent applicable expense waivers, reimbursements or
fee "breakpoints" are observed for the Fund, (v) information regarding MFS'
financial results and financial condition, including MFS' and certain of its
affiliates' estimated profitability from services performed for the Fund and
the MFS Funds as a whole, (vi) MFS' views regarding the outlook for the mutual
fund industry and the strategic business plans of MFS, (vii) descriptions of
various functions performed by MFS for the Funds, such as compliance
monitoring and portfolio trading practices, and (viii) information regarding
the overall organization of MFS, including information about MFS' senior
management and other personnel providing investment advisory, administrative
and other services to the Fund and the other MFS Funds. The comparative
performance, fee and expense information prepared and provided by Lipper Inc.
was not independently verified and the independent Trustees did not
independently verify any information provided to them by MFS.

The Trustees' conclusion as to the continuation of the investment advisory
agreement was based on a comprehensive consideration of all information
provided to the Trustees and not the result of any single factor. Some of the
factors that figured particularly in the Trustees' deliberations are described
below, although individual Trustees may have evaluated the information
presented differently from one another, giving different weights to various
factors. It is also important to recognize that the fee arrangements for the
Fund and other MFS Funds are the result of years of review and discussion
between the independent Trustees and MFS, that certain aspects of such
arrangements may receive greater scrutiny in some years than others, and that
the Trustees' conclusions may be based, in part, on their consideration of
these same arrangements during the course of the year and in prior years.

Based on information provided by Lipper Inc. and MFS, the Trustees reviewed
the Fund's total return investment performance as well as the performance of
peer groups of funds over various time periods. The Trustees placed particular
emphasis on the total return performance of the Fund's Class A shares in
comparison to the performance of funds in its Lipper performance universe over
the three-year period ended December 31, 2005, which the Trustees believed was
a long enough period to reflect differing market conditions. The Fund's
performance was in the 2nd quintile relative to the other funds in the
universe for this three-year period (the 1st quintile being the best
performers and the 5th quintile being the worst performers). The total
return performance of the Fund's Class A shares was in the 1st quintile
for the one-year period and the 1st quintile for the five-year period
ended December 31, 2005 relative to the Lipper performance universe. Because
of the passage of time, these performance results are likely to differ from
the performance results for more recent periods, including those shown
elsewhere in this report.

In the course of their deliberations, the Trustees took into account
information provided by MFS in connection with the contract review meetings,
as well as during investment review meetings conducted with portfolio
management personnel during the course of the year regarding the Fund's
performance. After reviewing these and related factors, the Trustees
concluded, within the context of their overall conclusions regarding the
investment advisory agreement, that they were satisfied with MFS' responses
and efforts relating to investment performance.

In assessing the reasonableness of the Fund's advisory fee, the Trustees
considered, among other information, the Fund's advisory fee and the total
expense ratio of the Fund's Class A shares as a percentage of average net
assets and the advisory fee and total expense ratios of peer groups of funds
based on information provided by Lipper Inc. and MFS. The Trustees considered
that there is an advisory fee reduction in effect for the Fund through
February 28, 2009 as part of MFS' settlement with the New York Attorney
General concerning market timing and related matters and that MFS has agreed
in writing to observe an expense limitation for the Fund. The Trustees also
considered that, according to the Lipper data, the Fund's effective advisory
fee rate (taking into account the advisory fee reduction and expense
limitation) and total expense ratio were each lower than the Lipper expense
group median.

The Trustees also considered the advisory fees charged by MFS to institutional
accounts. In comparing these fees, the Trustees considered information
provided by MFS as to the generally broader scope of services provided by MFS
to the Fund in comparison to institutional accounts, the higher demands placed
on MFS' investment personnel and trading infrastructure as a result of the
daily cash in-flows and out-flows of the Fund, and the impact on MFS and
expenses associated with the more extensive regulatory regime to which the
Fund is subject in comparison to institutional accounts.

The Trustees also considered whether the Fund is likely to benefit from any
economies of scale in the management of the Fund in the event of growth in
assets of the Fund. They noted that the Fund's advisory fee rate schedule is
not currently subject to any breakpoints. Taking into account the advisory fee
reduction and expense limitation described above, the Trustees determined not
to recommend any advisory fee breakpoints for the Fund at this time.

The Trustees also considered information prepared by MFS relating to MFS'
costs and profits with respect to the Fund, the MFS Funds considered as a
group, and other investment companies and accounts advised by MFS, as
well as MFS' methodologies used to determine and allocate its costs to the MFS
Funds, the Fund and other accounts and products for purposes of estimating
profitability.

After reviewing these and other factors described herein, the Trustees
concluded, within the context of their overall conclusions regarding the
investment advisory agreement, that the advisory fees charged to the Fund
represent reasonable compensation in light of the services being provided by
MFS to the Fund.

In addition, the Trustees considered MFS' resources and related efforts to
continue to retain, attract and motivate capable personnel to serve the Fund.
The Trustees also considered current and developing conditions in the
financial services industry, including the entry into the industry of large
and well-capitalized companies which are spending, and appear to be prepared
to continue to spend, substantial sums to engage personnel and to provide
services to competing investment companies. In this regard, the Trustees also
considered the financial resources of MFS and its ultimate parent, Sun Life
Financial Inc. The Trustees also considered the advantages and possible
disadvantages to the Fund of having an adviser which also serves other
investment companies as well as other accounts.

The Trustees also considered the nature, quality, cost, and extent of
administrative, transfer agency, and distribution services provided to the
Fund by MFS and its affiliates under agreements and plans other than the
investment advisory agreement, including any 12b-1 fees the Fund pays to MFS
Fund Distributors, Inc., an affiliate of MFS. The Trustees also considered the
nature, extent and quality of certain other services MFS performs or arranges
for on the Fund's behalf, including securities lending programs, directed
expense payment programs, class action recovery programs, and MFS' interaction
with third-party service providers, principally custodians and sub-custodians.
The Trustees concluded that the various non-advisory services provided by MFS
and its affiliates on behalf of the Funds were satisfactory.

The Trustees also considered benefits to MFS from the use of the Fund's
portfolio brokerage commissions to pay for investment research (excluding
third-party research, for which MFS pays directly) and various other factors.
Additionally, the Trustees considered so-called "fall-out benefits" to MFS
such as reputational value derived from serving as investment manager to the
Fund.

Based on their evaluation of factors that they deemed to be material,
including those factors described above, the Board of Trustees, including a
majority of the independent Trustees, concluded that the Fund's investment
advisory agreement with MFS should be continued for an additional one-year
period, commencing August 1, 2006.

A discussion regarding the Board's most recent review and renewal of the
fund's investment advisory agreement with MFS will be available on or before
November 1, 2006 by clicking on the fund's name under "Select a fund" on the
MFS Web site (mfs.com).

LETTER FROM THE CEO

[Photo of Robert J. Manning]

Dear Shareholders:

The story is as old as the tortoise and the hare, but we believe it is still
relevant today -- "slow and steady" is the way to go when it comes to
investing. While financial markets will naturally ebb and flow over time,
investors who remain committed to a long-term investment strategy are more
likely to achieve their goals than those who consistently chase short-term
performance.

The first half of 2006 brought a high degree of fluctuation in markets around
the globe as varying economic factors pulled markets in opposite directions.
The global economy, for example, continued to grow at its fastest pace in
three decades -- spurred by increased international trade, good job growth,
and wage increases. At the same time, central banks around the world raised
interest rates in sync in a collaborative attempt to curb inflation. While
this was a positive development in some regions, in other cases, economic and
market gains were tempered.

What does all of this mean to you as an investor? If you're focused on the
long term, these global developments become part of a longer cycle instead of
one-time events that can have a significant impact on your portfolio.

At MFS(R), our investment management process -- honed over 80 years --
combines a unique teamwork approach with an unwavering focus on helping you
realize your long-term financial goals. We believe in a three-pronged
investment strategy:

  o ALLOCATE holdings across the major asset classes -- including stocks,
    bonds, and cash.

  o DIVERSIFY within each class to take advantage of different market segments
    and investing styles.

  o REBALANCE assets regularly to maintain a desired asset allocation.

Of course, these strategies cannot guarantee a profit or protect against a
loss. Investing and planning for the long term requires diligence and
patience, two traits that in our experience are essential to capitalizing on
the many opportunities the financial markets can offer -- through both up and
down economic cycles.

    Respectfully,

/s/ Robert J. Manning

              Average Credit Quality of Rated
              Securities (short-term) (a)                  A-1
              ------------------------------------------------

(a) The average credit quality of rated securities is based upon a market
    weighted average of portfolio holdings that are rated by public rating
    agencies.
(d) Duration is a measure of how much a bond's price is likely to fluctuate
    with general changes in interest rates, e.g., if rates rise 1.00%, a bond
    with a 5-year duration is likely to lose about 5.00% of its value.
(i) For purposes of this graphical presentation, the bond component includes
    both accrued interest amounts and the equivalent exposure from any
    derivative holdings, if applicable.
(m) The average maturity shown is calculated using the final stated maturity on
    the portfolio's holdings without taking into account any holdings which
    have been pre-refunded or pre-paid to an earlier date or which have a
    mandatory put date prior to the stated maturity. The average life shown
    takes into account these earlier dates.
(r) Each security is assigned a rating from Moody's Investors Service. If not
    rated by Moody's, the rating will be that assigned by Standard & Poor's.
    Likewise, if not assigned a rating by Standard & Poor's, it will be based
    on the rating assigned by Fitch, Inc. For those portfolios that hold a
    security which is not rated by any of the three agencies, the security is
    considered Not Rated. Holdings in U.S. Treasuries and government agency
    mortgage-backed securities, if any, are included in a "AAA"-rating
    category. Percentages are based on the total market value of investments as
    of 7/31/06.

Percentages are based on net assets as of 7/31/06, unless otherwise noted.

The portfolio is actively managed, and current holdings may be different.


EXPENSE TABLE

Fund expenses borne by the shareholders during the period,
February 1, 2006 through July 31, 2006.

As a shareholder of the fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on certain purchase or redemption
payments and redemption fees on certain exchanges and redemptions, and (2)
ongoing costs, including management fees; distribution and service (12b-1)
fees; and other fund expenses. This example is intended to help you understand
your ongoing costs (in dollars) of investing in the fund and to compare these
costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning
of the period and held for the entire period February 1, 2006 through
July 31, 2006.

ACTUAL EXPENSES

The first line for each share class in the following table provides
information about actual account values and actual expenses. You may use the
information in this line, together with the amount you invested, to estimate
the expenses that you paid over the period. Simply divide your account value
by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then
multiply the result by the number in the first line under the heading entitled
"Expenses Paid During Period" to estimate the expenses you paid on your
account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line for each share class in the following table provides
information about hypothetical account values and hypothetical expenses based
on the fund's actual expense ratio and an assumed rate of return of 5% per
year before expenses, which is not the fund's actual return. The hypothetical
account values and expenses may not be used to estimate the actual ending
account balance or expenses you paid for the period. You may use this
information to compare the ongoing costs of investing in the fund and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or redemption fees. Therefore, the second line for each share
class in the table is useful in comparing ongoing costs only, and will not
help you determine the relative total costs of owning different funds. In
addition, if these transactional costs were included, your costs would have
been higher.

(h) 5% class return per year before expenses.

(p) Expenses paid is equal to each class' annualized expense ratio, as shown
    above, multiplied by the average account value over the period, multiplied
    by the number of days in the period, divided by the number of days in the
    year. Expenses paid do not include any applicable sales charges (loads) or
    redemption fees. If these transaction costs had been included, your costs
    would have been higher.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the fund's financial performance for the semiannual period
and the past 5 fiscal years (or life of a particular share class, if shorter). Certain information reflects financial results
for a single fund share. The total returns in the table represent the rate by which an investor would have earned (or lost) on
an investment in the fund share class (assuming reinvestment of all distributions) held for the entire period.

NOTES TO FINANCIAL STATEMENTS
(unaudited)

(1) BUSINESS AND ORGANIZATION

MFS High Income Fund (the fund) is a series of MFS Series Trust III (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 U.S.
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. The
fund can 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 fund can invest in
foreign securities, including securities of emerging market issuers.
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. The markets of emerging markets countries are generally more
volatile than the markets of developed countries with more mature economies.
All of the risks of investing in foreign securities previously described are
heightened when investing in emerging markets countries.

INVESTMENT VALUATIONS - Equity securities, including restricted equity
securities, are generally valued at the last sale or official closing price as
reported by an independent pricing service on the market or exchange on which
they are primarily traded. For securities for which there were no sales
reported that day, equity securities are generally valued at the last quoted
daily bid quotation as reported by an independent pricing service on the
market or exchange on which they are primarily traded. Debt instruments (other
than short-term instruments), including restricted debt instruments, are
generally valued at an evaluated or composite bid as reported by an
independent pricing service. Values of debt instruments obtained from pricing
services can utilize both dealer-supplied valuations and electronic data
processing techniques, which take into account 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. Short-
term instruments with a maturity at issuance of 60 days or less may be valued
at amortized cost, which approximates market value. Forward foreign currency
contracts are generally valued at the mean of bid and asked prices for the
time period interpolated from rates reported by an independent pricing service
for proximate time periods. Securities and other assets generally valued on
the basis of information from an independent pricing service may also be
valued at a broker-dealer bid quotation. The values of foreign securities and
other assets and liabilities expressed in foreign currencies are converted to
U.S. dollars using the mean of bid and asked prices for rates reported by an
independent pricing service. The Board of Trustees has delegated primary
responsibility for determining or causing to be determined the value of the
fund's investments (including any fair valuation) to the adviser pursuant to
valuation policies and procedures approved by the Board. If the adviser
determines that reliable market quotations are not readily available,
investments are valued at fair value as determined in good faith by the
adviser in accordance with such procedures under the oversight of the Board of
Trustees. Under the fund's valuation policies and procedures, market
quotations are not considered to be readily available for many types of debt
instruments. These investments are generally valued at fair value based on
information from independent pricing services. The adviser may rely on
independent pricing services or other information (such as the correlation
with price movements of similar securities in the same or other markets; the
type, cost and investment characteristics of the security; the business and
financial condition of the issuer; and trading and other market data) to
assist in determining whether to fair value and at what value to fair value an
investment. The value of an investment for purposes of calculating the fund's
net asset value can differ depending on the source and method used to
determine value. When fair valuation is used, the value of investments used to
determine the fund's net asset value may differ from quoted or published
prices for the same investments. In addition, investments may be valued at
fair value if the adviser determines that an investment's value has been
materially affected by events occurring after the close of the exchange or
market on which the investment is principally traded (such as foreign exchange
or market) and prior to the determination of the fund's net asset value, or
after the halting of trading of a specific security where trading does not
resume prior to the close of the exchange or market on which the security is
principally traded. Events that occur on a frequent basis after foreign
markets close (such as developments in foreign markets and significant
movements in the U.S. markets) and prior to the determination of the fund's
net asset value may be deemed to have a material affect on the value of
securities traded in foreign markets. Accordingly, the fund's foreign equity
securities may often be valued at fair value.

REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with
institutions that the fund's investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. The fund requires
that the securities collateral in a repurchase transaction be transferred to
the custodian in a manner sufficient to enable the fund to obtain those
securities in the event of a default under the repurchase agreement. The fund
monitors, on a daily basis, the value of the collateral to ensure that its
value, including accrued interest, is greater than amounts owed to the fund
under each such repurchase agreement. The fund, along with other affiliated
entities of Massachusetts Financial Services Company (MFS), may utilize a joint
trading account for the purpose of entering into one or more repurchase
agreements.

FOREIGN CURRENCY TRANSLATION - 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.

DERIVATIVE RISK - The fund may invest in derivatives for hedging or non-
hedging purposes. While hedging can reduce or eliminate losses, it can also
reduce or eliminate gains. When the fund uses derivatives as an investment to
gain market exposure, or for hedging purposes, gains and losses from
derivative instruments may be substantially greater than the derivative's
original cost. Derivative instruments include forward foreign currency
exchange contracts.

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 the contract. The fund may enter into forward foreign currency
exchange contracts for hedging purposes as well as for non-hedging purposes.
For hedging purposes, the fund may enter into contracts to deliver or receive
foreign currency it will receive from or require for its normal investment
activities. The fund may also use contracts in a manner intended to protect
foreign currency denominated securities from declines in value due to
unfavorable exchange rate movements. For non-hedging purposes, the fund may
enter into contracts with the intent of changing the relative exposure of the
fund's portfolio of securities to different currencies to take advantage of
anticipated changes. The forward foreign currency exchange contracts are
adjusted by the daily exchange rate of the underlying currency and any gains
or losses are recorded as unrealized until the contract settlement date. On
contract settlement date, the gains or losses are recorded as realized gains
or losses on foreign currency transactions.

LOANS AND OTHER DIRECT DEBT INSTRUMENTS - The fund may invest in loans and
loan participations or other receivables. These investments may include
standby financing commitments, including revolving credit facilities, which
obligate the fund to supply additional cash to the borrower on demand. Loan
participations involve a risk of insolvency of the lending bank or other
financial intermediary.

SHORT TERM FEES - For purchases made on or after July 1, 2004 and before April
1, 2005, the fund charged a 2% redemption fee (which was retained by the fund)
on proceeds from Class A, Class B, Class C, and Class I shares redeemed or
exchanged within 30 calendar days following their acquisition (either by
purchase or exchange). Effective April 1, 2005, the fund charges a 1%
redemption fee on proceeds from Class A, Class B, Class C, and Class I shares
redeemed or exchanged within 30 calendar days following their acquisition. The
fund may change the redemption fee period in the future, including in
connection with Securities and Exchange Commission rule developments. See the
fund's prospectus for details. Any redemption fees are accounted for as an
addition to paid-in capital.

INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on
the trade date. Interest income is recorded on the accrual basis. All premium
and discount is amortized or accreted for financial statement purposes in
accordance with U.S. generally accepted accounting principles. All discount is
accreted for tax reporting purposes as required by federal income tax
regulations. The fund earns certain fees in connection with its floating rate
loan purchasing activities. These fees are in addition to interest payments
earned and may include amendment fees, commitment fees, consent fees, and
prepayment fees. These fees are recorded on an accrual basis as income in the
accompanying financial statements. Dividends received in cash are recorded on
the ex-dividend date. Certain dividends from foreign securities will be
recorded when the fund is informed of the dividend if such information is
obtained subsequent to 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 fund may receive proceeds from litigation settlements involving its
portfolio holdings. Any proceeds received are reflected in realized gain/loss
in the Statement of Operations, or in unrealized gain/loss if the security is
still held by the fund.

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 made directly to the security issuer,
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 - The fund's custody fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by
the fund. This amount, for the six months ended July 31, 2006, is shown as a
reduction of total expenses on the Statement of Operations.

TAX MATTERS AND DISTRIBUTIONS - The fund intends to qualify as a regulated
investment company, as defined under Subchapter M of the Internal Revenue
Code, and to distribute all of its taxable income, including realized capital
gains. Accordingly, no provision for federal income tax is required in the
financial statements. Foreign taxes, if any, have been accrued by the fund in
the accompanying financial statements.

Distributions to shareholders are recorded on the ex-dividend date. Income and
capital gain distributions are determined in accordance with income tax
regulations, which may differ from generally accepted accounting principles.
Certain capital accounts in the financial statements are periodically adjusted
for permanent differences in order to reflect their tax character. These
adjustments have no impact on net assets or net asset value per share.
Temporary differences which arise from recognizing certain items of income,
expense, gain or loss in different periods for financial statement and tax
purposes will reverse at some time in the future. Distributions in excess of
net investment income or net realized gains are temporary overdistributions
for financial statement purposes resulting from differences in the recognition
or classification of income or distributions for financial statement and tax
purposes.

Book/tax differences primarily relate to amortization and accretion of debt
securities, defaulted bonds and foreign currency transactions.

The tax character of distributions made during the current period will be
determined at fiscal year end. The tax character of distributions declared to
shareholders is as follows:

                                                    1/31/06             1/31/05

Ordinary income (including any short-term
  capital gains)                               $102,443,896        $113,094,388

The federal tax cost and the tax basis components of distributable earnings
were as follows:

          Net unrealized appreciation (depreciation)     (31,068,527)

The aggregate cost above includes prior fiscal year end tax adjustments.

As of January 31, 2006, the fund had capital loss carryforwards available to
offset future realized gains. Such losses expire as follows:

                                                       $(389,086,167)

In June 2006, FASB Interpretation No. 48, Accounting for Uncertainty in Income
Taxes (the "Interpretation") was issued, and is effective for fiscal years
beginning after December 15, 2006 and is to be applied to all open tax years
as of the effective date. This Interpretation prescribes a minimum threshold
for financial statement recognition of the benefit of a tax position taken or
expected to be taken in a tax return, and requires certain expanded
disclosures. Management has recently begun to evaluate the application of
the Interpretation to the fund, and has not at this time determined the
impact, if any, resulting from the adoption of this Interpretation on the
fund's financial statements.

MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple
classes of shares, which differ in their respective distribution and service
fees. All shareholders bear the common expenses of the fund based on the value
of settled shares outstanding of each class, without distinction between share
classes. Dividends are declared separately for each class. Differences in per
share dividend rates are generally due to differences in separate class
expenses. Class B and Class 529B shares will convert to Class A and Class 529A
shares, respectively, approximately eight years after purchase.

(3) TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISER - The fund has an investment advisory agreement with 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 $1.4 billion of average daily net assets        0.46%
          Average daily net assets in excess of $1.4 billion    0.44%

As part of a settlement agreement with the New York Attorney General
concerning market timing and related matters, MFS has agreed to reduce the
management fee to 0.39% of the fund's average daily net assets in excess of
$1.4 billion for the period March 1, 2004 through February 28, 2009. For the
six months ended July 31, 2006, the fund's average daily net assets did not
exceed $1.4 billion and therefore, the management fee was not reduced.

The management fee incurred for the six months ended July 31, 2006 was
equivalent to an annual effective rate of 0.46% of the fund's average daily
net assets.

DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of
MFS, as distributor, received $33,093 and $561 for the six months ended July
31, 2006, as its portion of the initial sales charge on sales of Class A and
Class 529A shares of the fund, respectively.

The Board of Trustees has adopted a distribution plan for certain class shares
pursuant to Rule 12b-1 of the Investment Company Act of 1940.

The fund's distribution plan provides that the fund will pay MFD for services
provided by MFD and financial intermediaries in connection with the
distribution and servicing of certain share classes. One component of the plan
is a distribution fee paid to MFD and another component of the plan is a
service fee paid to MFD. MFD may subsequently pay all, or a portion, of the
distribution and/or service fees to financial intermediaries.

MFSC receives a fee from the fund, for its services as shareholder servicing
agent, set periodically under the supervision of the fund's Board of Trustees.
For the six months ended July 31, 2006, the fee was $627,676, which equated to
0.0995% annually of the fund's average daily net assets. MFSC also receives
payment from the fund for out-of-pocket and sub-accounting expenses paid by

these services, subject to review and approval by the Board of Trustees. Each
fund is charged a fixed amount plus a fee based on calendar year average net
assets. From July 1, 2005 through March 31, 2006, the fund's annual fixed
amount was $10,000. Effective April 1, 2006, the fund's annual fixed amount is
$17,500.

administration and services with respect to certain shares. These services
include various administrative, recordkeeping, and communication/educational
services with respect to the retirement plans which invest in these shares,
and may be provided directly by MFS or by a third party. MFS may subsequently
pay all, or a portion, of the retirement plan administration and services fee
to affiliated or unaffiliated third parties. For the six months ended July 31,
2006, the fund paid MFS an annual retirement plan administration and services
fee up to the following annual percentage rates of each class' average daily

TRUSTEES' AND OFFICERS' COMPENSATION - The fund pays compensation to
Independent Trustees in the form of a retainer, attendance fees, and
additional compensation to Board and Committee chairpersons. The fund does not
pay compensation directly to Trustees or officers of the fund who are also

services to the fund from MFS. Certain officers and Trustees of the fund are

The fund has an unfunded, defined benefit plan for certain retired Independent
Trustees which resulted in a pension expense of $3,705. The fund also has an

which resulted in an expense of $1,385. Both amounts are included in
Independent trustees' compensation for the six months ended July 31, 2006. The
deferred liability for retirement benefits payable to certain Trustees under
both plans amounted to $133,096 at July 31, 2006, and is included in payable
for independent trustees' compensation.

(i) For the period from the class' inception, April 1, 2005 (Classes R1, R2, R4, and R5), through the
    stated period end.


The fund is one of several mutual funds in which the MFS funds-of-funds may
invest. The MFS funds-of-funds do not invest in the underlying MFS funds for
the purpose of exercising management or control. At the end of the period, the
MFS Moderate Allocation Fund and MFS Growth Allocation Fund were the owners of
record of approximately 8% and 9%, respectively, of the value of outstanding
voting shares. In addition, the MFS Lifetime 2020 Fund and the MFS Lifetime
2030 Fund were each the owners of record of less than 1% of the value of
outstanding voting shares.

(6) LINE OF CREDIT

The fund and other affiliated funds participate in a $1 billion unsecured
committed line of credit provided by a syndication of banks under a credit
agreement. In addition, the fund and other affiliated funds have established
uncommitted borrowing arrangements with certain banks. Borrowings may be made
for temporary financing needs. Interest is charged to each fund, based on its
borrowings, generally at a rate equal to the Federal Reserve funds rate plus
0.35%. In addition, a commitment fee, based on the average daily, unused
portion of the committed line of credit, is allocated among the participating
funds at the end of each calendar quarter. For the six months ended
July 31, 2006, the fund's commitment fee and interest expense were $4,125 and
$0, respectively, and are included in miscellaneous expense on the Statement
of Operations.


BOARD REVIEW OF INVESTMENT

ADVISORY AGREEMENT

The Investment Company Act of 1940 requires that both the full Board of
Trustees and a majority of the non-interested ("independent") Trustees, voting
separately, annually approve the continuation of the Fund's investment
advisory agreement with MFS. The Trustees consider matters bearing on the Fund
and its advisory arrangements at their meetings throughout the year, including
a review of performance data at each regular meeting. In addition, the
independent Trustees met several times over the course of three months
beginning in May and ending in July, 2006 ("contract review meetings") for the
specific purpose of considering whether to approve the continuation of the
investment advisory agreement for the Fund and the other investment companies
that the Board oversees (the "MFS Funds"). The independent Trustees were
assisted in their evaluation of the Fund's investment advisory agreement by
independent legal counsel, from whom they received separate legal advice and
with whom they met separately from MFS during various contract review
meetings. The independent Trustees were also assisted in this process by the
MFS Funds' Independent Chief Compliance Officer, a full-time senior officer
appointed by and reporting to the independent Trustees.

In connection with their deliberations regarding the continuation of the
investment advisory agreement, the Trustees, including the independent
Trustees, considered such information and factors as they believed, in light
of the legal advice furnished to them and their own business judgment, to be
relevant. The investment advisory agreement for the Fund was considered
separately, although the Trustees also took into account the common interests
of all MFS Funds in their review. As described below, the Trustees considered
the nature, quality, and extent of the various investment advisory,
administrative, and shareholder services performed by MFS under the existing
investment advisory agreement and other arrangements with the Fund.

In connection with their contract review meetings, the Trustees received and
relied upon materials which included, among other items: (i) information
provided by Lipper Inc. on the investment performance of the Fund for various
time periods ended December 31, 2005 and the investment performance of a group
of funds with substantially similar investment classifications/objectives (the
"Lipper performance universe"), as well as the investment performance of a
group of funds identified by objective criteria suggested by MFS ("MFS peer
funds"), (ii) information provided by Lipper Inc. on the Fund's advisory fees
and other expenses and the advisory fees and other expenses of comparable
funds identified by Lipper (the "Lipper expense group"), as well as the
advisory fees and other expenses of MFS peer funds, (iii) information provided
by MFS on the advisory fees of comparable portfolios of other clients of MFS,
including institutional separate accounts and other clients, (iv) information
as to whether and to what extent applicable expense waivers, reimbursements or
fee "breakpoints" are observed for the Fund, (v) information regarding MFS'
financial results and financial condition, including MFS' and certain of its
affiliates' estimated profitability from services performed for the Fund and
the MFS Funds as a whole, (vi) MFS' views regarding the outlook for the mutual
fund industry and the strategic business plans of MFS, (vii) descriptions of
various functions performed by MFS for the Funds, such as compliance
monitoring and portfolio trading practices, and (viii) information regarding
the overall organization of MFS, including information about MFS' senior
management and other personnel providing investment advisory, administrative
and other services to the Fund and the other MFS Funds. The comparative
performance, fee and expense information prepared and provided by Lipper Inc.
was not independently verified and the independent Trustees did not
independently verify any information provided to them by MFS.

The Trustees' conclusion as to the continuation of the investment advisory
agreement was based on a comprehensive consideration of all information
provided to the Trustees and not the result of any single factor. Some of the
factors that figured particularly in the Trustees' deliberations are described
below, although individual Trustees may have evaluated the information
presented differently from one another, giving different weights to various
factors. It is also important to recognize that the fee arrangements for the
Fund and other MFS Funds are the result of years of review and discussion
between the independent Trustees and MFS, that certain aspects of such
arrangements may receive greater scrutiny in some years than others, and that
the Trustees' conclusions may be based, in part, on their consideration of
these same arrangements during the course of the year and in prior years.

Based on information provided by Lipper Inc. and MFS, the Trustees reviewed
the Fund's total return investment performance as well as the performance of
peer groups of funds over various time periods. The Trustees placed particular
emphasis on the total return performance of the Fund's Class A shares in
comparison to the performance of funds in its Lipper performance universe over
the three-year period ended December 31, 2005, which the Trustees believed was
a long enough period to reflect differing market conditions. The Fund's
performance was in the 4th quintile relative to the other funds in the
universe for this three-year period (the 1st quintile being the best
performers and the 5th quintile being the worst performers). The total
return performance of the Fund's Class A shares was in the 3rd quintile
for the one-year period and the 3rd quintile for the five-year period
ended December 31, 2005 relative to the Lipper performance universe. Because
of the passage of time, these performance results are likely to differ from
the performance results for more recent periods, including those shown
elsewhere in this report.

The Trustees expressed concern to MFS about the ongoing substandard investment
performance of the Fund. In the course of their deliberations, the Trustees
took into account information provided by MFS in connection with the contract
review meetings, as well as during investment review meetings conducted with
portfolio management personnel during the course of the year, as to MFS'
efforts to improve the Fund's performance, including the recent restructuring
of responsibilities among MFS' senior investment management executives and the
addition of a second portfolio manager in 2004. In addition, the Trustees
requested that they receive a separate update on the Fund's performance at
each of their meetings and a more in-depth review of the Fund's performance
quarterly. After reviewing these and related factors, the Trustees concluded,
within the context of their overall conclusions regarding the investment
advisory agreement, that MFS' responses and efforts and plans to improve
investment performance were sufficient to support approval of the continuance
of the investment advisory agreement for an additional one year period, but
that they would continue to closely monitor the performance of the Fund.

In assessing the reasonableness of the Fund's advisory fee, the Trustees
considered, among other information, the Fund's advisory fee and the total
expense ratio of the Fund's Class A shares as a percentage of average net
assets and the advisory fee and total expense ratios of peer groups of funds
based on information provided by Lipper Inc. and MFS. The Trustees considered
that there is an advisory fee reduction on assets over $1.4 billion, which is
in effect for the Fund through February 28, 2009 as part of MFS' settlement
with the New York Attorney General concerning market timing and related
matters. The Trustees also considered that, according to the Lipper data, the
Fund's effective advisory fee rate was lower than the Lipper expense group
median, and the Fund's total expense ratio was approximately at the Lipper
expense group median.

The Trustees also considered the advisory fees charged by MFS to institutional
accounts. In comparing these fees, the Trustees considered information
provided by MFS as to the generally broader scope of services provided by MFS
to the Fund in comparison to institutional accounts, the higher demands placed
on MFS' investment personnel and trading infrastructure as a result of the
daily cash in-flows and out-flows of the Fund, and the impact on MFS and
expenses associated with the more extensive regulatory regime to which the
Fund is subject in comparison to institutional accounts.

The Trustees also considered whether the Fund is likely to benefit from any
economies of scale in the management of the Fund in the event of growth in
assets of the Fund. They noted that the Fund's advisory fee rate schedule is
subject to a contractual breakpoint that reduces the fund's advisory fee rate
on net assets over $1.4 billion and that the advisory fee associated with such
breakpoint is reduced during the period in which the advisory fee reduction
described above is in effect. The Trustees concluded that the existing
breakpoint was sufficient to allow the Fund to benefit from economies of scale
as its assets grow.

The Trustees also considered information prepared by MFS relating to MFS'
costs and profits with respect to the Fund, the MFS Funds considered as a
group, and other investment companies and accounts advised by MFS, as
well as MFS' methodologies used to determine and allocate its costs to the MFS
Funds, the Fund and other accounts and products for purposes of estimating
profitability.

After reviewing these and other factors described herein, the Trustees
concluded, within the context of their overall conclusions regarding the
investment advisory agreement, that the advisory fees charged to the Fund
represent reasonable compensation in light of the services being provided by
MFS to the Fund.

In addition, the Trustees considered MFS' resources and related efforts to
continue to retain, attract and motivate capable personnel to serve the Fund.
The Trustees also considered current and developing conditions in the
financial services industry, including the entry into the industry of large
and well-capitalized companies which are spending, and appear to be prepared
to continue to spend, substantial sums to engage personnel and to provide
services to competing investment companies. In this regard, the Trustees also
considered the financial resources of MFS and its ultimate parent, Sun Life
Financial Inc. The Trustees also considered the advantages and possible
disadvantages to the Fund of having an adviser which also serves other
investment companies as well as other accounts.

The Trustees also considered the nature, quality, cost, and extent of
administrative, transfer agency, and distribution services provided to the
Fund by MFS and its affiliates under agreements and plans other than the
investment advisory agreement, including any 12b-1 fees the Fund pays to MFS
Fund Distributors, Inc., an affiliate of MFS. The Trustees also considered the
nature, extent and quality of certain other services MFS performs or arranges
for on the Fund's behalf, including securities lending programs, directed
expense payment programs, class action recovery programs, and MFS' interaction
with third-party service providers, principally custodians and sub-custodians.
The Trustees concluded that the various non-advisory services provided by MFS
and its affiliates on behalf of the Funds were satisfactory.

The Trustees also considered benefits to MFS from the use of the Fund's
portfolio brokerage commissions to pay for investment research (excluding
third-party research, for which MFS pays directly) and various other factors.
Additionally, the Trustees considered so-called "fall-out benefits" to MFS such
as reputational value derived from serving as investment manager to the Fund.

Based on their evaluation of factors that they deemed to be material,
including those factors described above, the Board of Trustees, including a
majority of the independent Trustees, concluded that the Fund's investment
advisory agreement with MFS should be continued for an additional one-year
period, commencing August 1, 2006.

A discussion regarding the Board's most recent review and renewal of the
Fund's investment advisory agreement will be available on or before
November 1, 2006 by clicking on the fund's name under "Select a fund" on the
MFS Web site (mfs.com).

LETTER FROM THE CEO

[Photo of Robert J. Manning]

Dear Shareholders:

The story is as old as the tortoise and the hare, but we believe it is still
relevant today -- "slow and steady" is the way to go when it comes to investing.
While financial markets will naturally ebb and flow over time, investors who
remain committed to a long-term investment strategy are more likely to achieve
their goals than those who consistently chase short-term performance.

The first half of 2006 brought a high degree of fluctuation in markets around
the globe as varying economic factors pulled markets in opposite directions. The
global economy, for example, continued to grow at its fastest pace in three
decades -- spurred by increased international trade, good job growth, and wage
increases. At the same time, central banks around the world raised interest
rates in sync in a collaborative attempt to curb inflation. While this was a
positive development in some regions, in other cases, economic and market gains
were tempered.

What does all of this mean to you as an investor? If you're focused on the long
term, these global developments become part of a longer cycle instead of
one-time events that can have a significant impact on your portfolio.

At MFS(R), our investment management process -- honed over 80 years -- combines
a unique teamwork approach with an unwavering focus on helping you realize your
long-term financial goals. We believe in a three-pronged investment strategy:

  o ALLOCATE holdings across the major asset classes -- including stocks,
    bonds, and cash.

  o DIVERSIFY within each class to take advantage of different market segments
    and investing styles.

  o REBALANCE assets regularly to maintain a desired asset allocation.

Of course, these strategies cannot guarantee a profit or protect against a loss.
Investing and planning for the long term requires diligence and patience, two
traits that in our experience are essential to capitalizing on the many
opportunities the financial markets can offer -- through both up and down
economic cycles.

    Respectfully,

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

(a) The average credit quality of rated securities is based upon a market
    weighted average of portfolio holdings that are rated by public rating
    agencies.
(d) Duration is a measure of how much a bond's price is likely to fluctuate
    with general changes in interest rates, e.g., if rates rise 1.00%, a bond
    with a 5-year duration is likely to lose about 5.00% of its value.
(i) For purposes of this graphical presentation, the bond component includes
    both accrued interest amounts and the equivalent exposure from any
    derivative holdings, if applicable.
(m) The average maturity shown is calculated using the final stated maturity on
    the portfolio's holdings without taking into account any holdings which
    have been pre-refunded or pre-paid to an earlier date or which have a
    mandatory put date prior to the stated maturity. The average life shown
    takes into account these earlier dates.
(r) Each security is assigned a rating from Moody's Investors Service. If not
    rated by Moody's, the rating will be that assigned by Standard & Poor's.
    Likewise, if not assigned a rating by Standard & Poor's, it will be based
    on the rating assigned by Fitch, Inc. For those portfolios that hold a
    security which is not rated by any of the three agencies, the security is
    considered Not Rated. Holdings in U.S. Treasuries and government agency
    mortgage-backed securities, if any, are included in a "AAA"-rating
    category. Percentages are based on the total market value of investments as
    of 7/31/06.

Percentages are based on net assets as of 7/31/06, unless otherwise noted.

The portfolio is actively managed, and current holdings may be different.


EXPENSE TABLE

Fund expenses borne by the shareholders during the period, February 1, 2006
through July 31, 2006.

As a shareholder of the fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on certain purchase or redemption
payments and redemption fees on certain exchanges and redemptions, and (2)
ongoing costs, including management fees; distribution and service (12b-1) fees;
and other fund expenses. This example is intended to help you understand your
ongoing costs (in dollars) of investing in the fund and to compare these costs
with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period February 1, 2006 through July 31, 2006.

ACTUAL EXPENSES

The first line for each share class in the following table provides information
about actual account values and actual expenses. You may use the information in
this line, together with the amount you invested, to estimate the expenses that
you paid over the period. Simply divide your account value by $1,000 (for
example, an $8,600 account value divided by $1,000 = 8.6), then multiply the
result by the number in the first line under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line for each share class in the following table provides information
about hypothetical account values and hypothetical expenses based on the fund's
actual expense ratio and an assumed rate of return of 5% per year before
expenses, which is not the fund's actual return. The hypothetical account values
and expenses may not be used to estimate the actual ending account balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the fund and other funds. To do so, compare this
5% hypothetical example with the 5% hypothetical examples that appear in the
shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or redemption fees. Therefore, the second line for each share
class in the table is useful in comparing ongoing costs only, and will not help
you determine the relative total costs of owning different funds. In addition,
if these transactional costs were included, your costs would have been higher.

(h) 5% class return per year before expenses.
(p) Expenses paid is equal to each class' annualized expense ratio, as shown
    above, multiplied by the average account value over the period, multiplied
    by the number of days in the period, divided by the number of days in the
    year. Expenses paid do not include any applicable sales charges (loads) or
    redemption fees. If these transaction costs had been included, your costs
    would have been higher.

NOTES TO FINANCIAL STATEMENTS
(unaudited)

(1) BUSINESS AND ORGANIZATION

MFS Municipal High Income Fund (the fund) is a series of MFS Series Trust III
(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 U.S.
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. The fund can
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. Municipal securities backed by
current or anticipated revenues from a specific project or specific assets can
be negatively affected by the discontinuance of the taxation supporting the
projects or assets or the inability to collect revenues for the project or from
the assets. If the Internal Revenue Service determines an issuer of a municipal
security has not complied with applicable tax requirements, the security could
decline in value, interest from the security could become taxable and the fund
may be required to issue Forms 1099-DIV.

INVESTMENT VALUATIONS - Debt instruments (other than short-term instruments),
including restricted debt instruments, are generally valued at an evaluated or
composite bid as reported by an independent pricing service. Values of debt
instruments obtained from pricing services can utilize both dealer-supplied
valuations and electronic data processing techniques, which take into account
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. Short-term instruments with a maturity at issuance of 60
days or less may be valued at amortized cost, which approximates market value.
Swaps are generally valued at a broker-dealer bid quotation. Securities and
other assets generally valued on the basis of information from an independent
pricing service may also be valued at a broker-dealer bid quotation. The Board
of Trustees has delegated primary responsibility for determining or causing to
be determined the value of the fund's investments (including any fair
valuation) to the adviser pursuant to valuation policies and procedures
approved by the Board. If the adviser determines that reliable market
quotations are not readily available, investments are valued at fair value as
determined in good faith by the adviser in accordance with such procedures
under the oversight of the Board of Trustees. Under the fund's valuation
policies and procedures, market quotations are not considered to be readily
available for many types of debt instruments. These investments are generally
valued at fair value based on information from independent pricing services.
The adviser may rely on independent pricing services or other information (such
as the correlation with price movements of similar securities in the same or
other markets; the type, cost and investment characteristics of the security;
the business and financial condition of the issuer; and trading and other
market data) to assist in determining whether to fair value and at what value
to fair value an investment. The value of an investment for purposes of
calculating the fund's net asset value can differ depending on the source and
method used to determine value. When fair valuation is used, the value of
investments used to determine the fund's net asset value may differ from quoted
or published prices for the same investments.

DERIVATIVE RISK - The fund may invest in derivatives for hedging or non-hedging
purposes. While hedging can reduce or eliminate losses, it can also reduce or
eliminate gains. When the fund uses derivatives as an investment to gain market
exposure, or for hedging purposes, gains and losses from derivative instruments
may be substantially greater than the derivative's original cost. Derivative
instruments include swap agreements.

SWAP AGREEMENTS - The fund may enter into swap agreements. A swap is an exchange
of cash payments between the fund and another party. Net cash payments are
exchanged at specified intervals and are recorded as a realized gain or loss in
the Statement of Operations. The value of the swap is adjusted daily and the
change in value is recorded as unrealized appreciation or depreciation in the
Statement of Operations. Risks may arise upon entering into these agreements
from the potential inability of counterparties to meet the terms of their
contract and from unanticipated changes in the value of the financial index on
which the swap agreement is based.

INTEREST RATE SWAP AGREEMENTS - Interest rate swap agreements are agreements to
exchange cash flows periodically based on a notional principal amount, such as
the exchange of fixed rate interest payments for floating rate interest
payments, which are based on a specific financial index, or the exchange of two
distinct floating rate payments. The net receivable or payable associated with
these payments is accrued daily and recorded as an unrealized gain or loss, and
any payments received or made are recorded as realized gains or losses, in the
Statement of Operations. The primary risk associated with interest rate swap
agreements is that unfavorable changes in the fluctuation of interest rates
could adversely impact the fund.

SHORT TERM FEES - For purchases made on or after July 1, 2004 and before April
1, 2005, the fund charged a 2% redemption fee (which was retained by the fund)
on proceeds from Class A, Class B, and Class C shares redeemed or exchanged
within 30 calendar days following their acquisition (either by purchase or
exchange). Effective April 1, 2005, the fund charges a 1% redemption fee on
proceeds from Class A, Class B, and Class C shares redeemed or exchanged within
30 calendar days following their acquisition. The fund may change the redemption
fee period in the future, including in connection with Securities and Exchange
Commission rule developments. See the fund's prospectus for details. Any
redemption fees are accounted for as an addition to paid-in capital.

INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the
trade date. Interest income is recorded on the accrual basis. All premium and
discount is amortized or accreted for financial statement purposes in accordance
with U.S. generally accepted accounting principles. All premium and original
issue discount is amortized or accreted for tax reporting purposes as required
by federal income tax regulations. The fund may receive proceeds from litigation
settlements involving its portfolio holdings. Any proceeds received are
reflected in realized gain/loss in the Statement of Operations, or in unrealized
gain/loss if the security is still held by the fund.

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 made directly to the security issuer,
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 - The fund's custody fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by the
fund. This amount, for the six months ended July 31, 2006, is shown as a
reduction of total expenses on the Statement of Operations.

TAX MATTERS AND DISTRIBUTIONS - The fund intends to qualify as a regulated
investment company, as defined under Subchapter M of the Internal Revenue Code,
and to distribute all of its taxable and tax-exempt income, including realized
capital gains. Accordingly, no provision for federal income tax is required in
the financial statements.

Distributions to shareholders are recorded on the ex-dividend date. Income and
capital gain distributions are determined in accordance with income tax
regulations, which may differ from generally accepted accounting principles.
Certain capital accounts in the financial statements are periodically adjusted
for permanent differences in order to reflect their tax character. These
adjustments have no impact on net assets or net asset value per share. Temporary
differences which arise from recognizing certain items of income, expense, gain
or loss in different periods for financial statement and tax purposes will
reverse at some time in the future. Distributions in excess of net investment
income or net realized gains are temporary overdistributions for financial
statement purposes resulting from differences in the recognition or
classification of income or distributions for financial statement and tax
purposes.

Book/tax differences primarily relate to expiration of capital loss
carryforwards, amortization and accretion of debt securities, and defaulted
bonds.

The tax character of distributions made during the current period will be
determined at fiscal year end. The tax character of distributions declared to
shareholders is as follows:

                                                        1/31/06         1/31/05

In June 2006, FASB Interpretation No. 48, Accounting for Uncertainty in Income
Taxes (the "Interpretation") was issued, and is effective for fiscal years
beginning after December 15, 2006 and is to be applied to all open tax years as
of the effective date. This Interpretation prescribes a minimum threshold for
financial statement recognition of the benefit of a tax position taken or
expected to be taken in a tax return, and requires certain expanded disclosures.
Management has recently begun to evaluate the application of the Interpretation
to the fund, and has not at this time determined the impact, if any, resulting
from the adoption of this Interpretation on the fund's financial statements.

MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple
classes of shares, which differ in their respective distribution and service
fees. All shareholders bear the common expenses of the fund based on the value
of settled shares outstanding of each class, without distinction between share
classes. Dividends are declared separately for each class. Differences in per
share dividend rates are generally due to differences in separate class
expenses. Class B 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 $1.4 billion of average daily net assets        0.60%
          Average daily net assets in excess of $1.4 billion    0.57%

As part of a settlement agreement with the New York Attorney General concerning
market timing and related matters, MFS has agreed to reduce the management fee
to 0.50% of the fund's average daily net assets for the period March 1, 2004
through February 28, 2009. For the six months ended July 31, 2006, this waiver
amounted to $715,109 and is reflected as a reduction of total expenses in the
Statement of Operations. The management fee incurred for the six months ended
July 31, 2006, was equivalent to an annual effective rate of 0.50% of the fund's
average daily net assets.

DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of
MFS, as distributor, received $269,786 for the six months ended July 31, 2006,
as its portion of the initial sales charge on sales of Class A shares of the
fund.

The Board of Trustees has adopted a distribution plan for certain class shares
pursuant to Rule 12b-1 of the Investment Company Act of 1940.

The fund's distribution plan provides that the fund will pay MFD for services
provided by MFD and financial intermediaries in connection with the distribution
and servicing of certain share classes. One component of the plan is a
distribution fee paid to MFD and another component of the plan is a service fee
paid to MFD. MFD may subsequently pay all, or a portion, of the distribution
and/or service fees to financial intermediaries.

(d) In accordance with the distribution plan for certain classes, the fund pays distribution and/or service fees up
    to these annual percentage rates of each class' average daily net assets.
(e) The annual effective rates represent actual fees incurred under the distribution plan for the six months ended
    July 31, 2006 based on each class' average daily net assets. For one year from the date of sale of Class B
    shares, assets attributable to such Class B shares are subject to the 0.25% annual Class B service fee.
    Otherwise, the service fee is not currently in effect, but may be implemented on such date as the fund's Board
    of Trustees may determine.


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 of purchase.
Class B shares are subject to a contingent deferred sales charge in the event of
a shareholder redemption within six years of purchase. All contingent deferred
sales charges are paid to MFD and during the six months ended July 31, 2006,
were as follows:

                                                              AMOUNT

              Class A                                         $1,322
              Class B                                       $145,420
              Class C                                        $16,446

SHAREHOLDER SERVICING AGENT - The fund pays a portion of shareholder servicing
costs to MFS Service Center, Inc. (MFSC), a wholly-owned subsidiary of MFS. MFSC
receives a fee from the fund, for its services as shareholder servicing agent,
set periodically under the supervision of the fund's Board of Trustees. For the
six months ended July 31, 2006, the fee was $719,206, which equated to 0.0993%
annually of the fund's average daily net assets. MFSC also receives payment from
the fund for out-of-pocket and sub-accounting expenses paid by MFSC on behalf of
the fund. For the six months ended July 31, 2006, these costs amounted to
$127,514.

ADMINISTRATOR - MFS provides certain financial, legal, shareholder
communications, compliance, and other administrative services to certain funds
for which MFS acts as investment adviser. Under an administrative services
agreement, the funds may partially reimburse MFS the costs incurred to provide
these services, subject to review and approval by the Board of Trustees. Each
fund is charged a fixed amount plus a fee based on calendar year average net
assets. From July 1, 2005 through March 31, 2006, the fund's annual fixed amount
was $10,000. Effective April 1, 2006, the fund's annual fixed amount is $17,500.
The administrative services fee incurred for the six months ended July 31, 2006
was equivalent to an annual effective rate of 0.0165% of the fund's average
daily net assets.

TRUSTEES' AND OFFICERS' COMPENSATION - The fund pays compensation to Independent
Trustees in the form of a retainer, attendance fees, and additional compensation
to Board and Committee chairpersons. The fund does not pay compensation directly
to Trustees or officers of the fund who are also officers of the investment
adviser, 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,
MFD, and MFSC. The fund has an unfunded, defined benefit plan for certain
retired Independent Trustees which resulted in a pension expense of $2,277. This
amount is included in Independent Trustees' compensation for the six months
ended July 31, 2006. The deferred liability for retirement benefits payable to
certain retired Trustees amounted to $51,360 at July 31, 2006, and is included
in payable for independent trustees' compensation.

OTHER - This fund and certain other MFS funds (the funds) have entered into a
services agreement (the Agreement) which provides for payment of fees by the
funds to Tarantino LLC in return for the provision of services of an Independent
Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the
funds and the sole member of Tarantino LLC. The funds can terminate the
Agreement with Tarantino LLC at any time under the terms of the Agreement. For
the six months ended July 31, 2006, the fee paid to Tarantino LLC was $5,761.
MFS has agreed to reimburse the fund for a portion of the payments made by the
funds to Tarantino LLC in the amount of $4,311, which is shown as a reduction of
total expenses in the Statement of Operations. Additionally, MFS has agreed to
bear all expenses associated with office space, other administrative support,
and supplies provided to the ICCO.

(6) LINE OF CREDIT

The fund and other affiliated funds participate in a $1 billion unsecured
committed line of credit provided by a syndication of banks under a credit
agreement. In addition, the fund and other affiliated funds have established
uncommitted borrowing arrangements with certain banks. Borrowings may be made
for temporary financing needs. Interest is charged to each fund, based on its
borrowings, generally at a rate equal to the Federal Reserve funds rate plus
0.35%. In addition, a commitment fee, based on the average daily, unused portion
of the committed line of credit, is allocated among the participating funds at
the end of each calendar quarter. For the six months ended July 31, 2006, the
fund's commitment fee and interest expense were $4,587 and $0, respectively, and
are included in miscellaneous expense on the Statement of Operations.

(7) CONCENTRATION OF CREDIT RISK

At July 31, 2006, 20.7% of securities in the portfolio of investments are backed
by letters of credit or bond insurance of various financial institutions and
financial guaranty assurance agencies. The percentage of investments insured by
or supported (backed) by a letter of credit from any one institution or agency
did not exceed 4.5% of total investments.


BOARD REVIEW OF INVESTMENT

ADVISORY AGREEMENT

The Investment Company Act of 1940 requires that both the full Board of Trustees
and a majority of the non-interested ("independent") Trustees, voting
separately, annually approve the continuation of the Fund's investment advisory
agreement with MFS. The Trustees consider matters bearing on the Fund and its
advisory arrangements at their meetings throughout the year, including a review
of performance data at each regular meeting. In addition, the independent
Trustees met several times over the course of three months beginning in May and
ending in July, 2006 ("contract review meetings") for the specific purpose of
considering whether to approve the continuation of the investment advisory
agreement for the Fund and the other investment companies that the Board
oversees (the "MFS Funds"). The independent Trustees were assisted in their
evaluation of the Fund's investment advisory agreement by independent legal
counsel, from whom they received separate legal advice and with whom they met
separately from MFS during various contract review meetings. The independent
Trustees were also assisted in this process by the MFS Funds' Independent Chief
Compliance Officer, a full-time senior officer appointed by and reporting to the
independent Trustees.

In connection with their deliberations regarding the continuation of the
investment advisory agreement, the Trustees, including the independent Trustees,
considered such information and factors as they believed, in light of the legal
advice furnished to them and their own business judgment, to be relevant. The
investment advisory agreement for the Fund was considered separately, although
the Trustees also took into account the common interests of all MFS Funds in
their review. As described below, the Trustees considered the nature, quality,
and extent of the various investment advisory, administrative, and shareholder
services performed by MFS under the existing investment advisory agreement and
other arrangements with the Fund.

In connection with their contract review meetings, the Trustees received and
relied upon materials which included, among other items: (i) information
provided by Lipper Inc. on the investment performance of the Fund for various
time periods ended December 31, 2005 and the investment performance of a group
of funds with substantially similar investment classifications/objectives (the
"Lipper performance universe"), as well as the investment performance of a
group of funds identified by objective criteria suggested by MFS ("MFS peer
funds"), (ii) information provided by Lipper Inc. on the Fund's advisory fees
and other expenses and the advisory fees and other expenses of comparable funds
identified by Lipper (the "Lipper expense group"), as well as the advisory fees
and other expenses of MFS peer funds, (iii) information provided by MFS on the
advisory fees of comparable portfolios of other clients of MFS, including
institutional separate accounts and other clients, (iv) information as to
whether and to what extent applicable expense waivers, reimbursements or fee
"breakpoints" are observed for the Fund, (v) information regarding MFS'
financial results and financial condition, including MFS' and certain of its
affiliates' estimated profitability from services performed for the Fund and
the MFS Funds as a whole, (vi) MFS' views regarding the outlook for the mutual
fund industry and the strategic business plans of MFS, (vii) descriptions of
various functions performed by MFS for the Funds, such as compliance monitoring
and portfolio trading practices, and (viii) information regarding the overall
organization of MFS, including information about MFS' senior management and
other personnel providing investment advisory, administrative and other
services to the Fund and the other MFS Funds. The comparative performance, fee
and expense information prepared and provided by Lipper Inc. was not
independently verified and the independent Trustees did not independently
verify any information provided to them by MFS.

The Trustees' conclusion as to the continuation of the investment advisory
agreement was based on a comprehensive consideration of all information provided
to the Trustees and not the result of any single factor. Some of the factors
that figured particularly in the Trustees' deliberations are described below,
although individual Trustees may have evaluated the information presented
differently from one another, giving different weights to various factors. It is
also important to recognize that the fee arrangements for the Fund and other MFS
Funds are the result of years of review and discussion between the independent
Trustees and MFS, that certain aspects of such arrangements may receive greater
scrutiny in some years than others, and that the Trustees' conclusions may be
based, in part, on their consideration of these same arrangements during the
course of the year and in prior years.

Based on information provided by Lipper Inc. and MFS, the Trustees reviewed the
Fund's total return investment performance as well as the performance of peer
groups of funds over various time periods. The Trustees placed particular
emphasis on the total return performance of the Fund's Class A shares in
comparison to the performance of funds in its Lipper performance universe over
the three-year period ended December 31, 2005, which the Trustees believed was
a long enough period to reflect differing market conditions. The Fund's
performance was in the 1st quintile relative to the other funds in the universe
for this three-year period (the 1st quintile being the best performers and the
5th quintile being the worst performers). The total return performance of the
Fund's Class A shares was in the 2nd quintile for the one-year period and the
2nd quintile for the five-year period ended December 31, 2005 relative to the
Lipper performance universe. Because of the passage of time, these performance
results are likely to differ from the performance results for more recent
periods, including those shown elsewhere in this report.

In the course of their deliberations, the Trustees took into account information
provided by MFS in connection with the contract review meetings, as well as
during investment review meetings conducted with portfolio management personnel
during the course of the year regarding the Fund's performance. After reviewing
these and related factors, the Trustees concluded, within the context of their
overall conclusions regarding the investment advisory agreement, that they were
satisfied with MFS' responses and efforts relating to investment performance.

In assessing the reasonableness of the Fund's advisory fee, the Trustees
considered, among other information, the Fund's advisory fee and the total
expense ratio of the Fund's Class A shares as a percentage of average net
assets and the advisory fee and total expense ratios of peer groups of funds
based on information provided by Lipper Inc. and MFS. The Trustees considered
that there is an advisory fee reduction in effect for the Fund through February
28, 2009 as part of MFS's settlement with the New York Attorney General
concerning market timing and related matters. The Trustees also considered
that, according to the Lipper data, the Fund's effective advisory fee rate
(taking into account the advisory fee reduction) was approximately at the
Lipper expense group median, and the Fund's total expense ratio was lower than
the Lipper expense group median.

The Trustees also considered the advisory fees charged by MFS to institutional
accounts. In comparing these fees, the Trustees considered information provided
by MFS as to the generally broader scope of services provided by MFS to the
Fund in comparison to institutional accounts, the higher demands placed on MFS'
investment personnel and trading infrastructure as a result of the daily cash
in-flows and out-flows of the Fund, and the impact on MFS and expenses
associated with the more extensive regulatory regime to which the Fund is
subject in comparison to institutional accounts.

The Trustees also considered whether the Fund is likely to benefit from any
economies of scale in the management of the Fund in the event of growth in
assets of the Fund. They noted that the Fund's advisory fee rate schedule is
subject to a contractual breakpoint. However, such breakpoint is not applicable
because the Fund is currently subject to the advisory fee reduction described
above. Accordingly, the Trustees determined not to recommend any advisory fee
breakpoint changes at this time.

The Trustees also considered information prepared by MFS relating to MFS' costs
and profits with respect to the Fund, the MFS Funds considered as a group, and
other investment companies and accounts advised by MFS, as well as MFS'
methodologies used to determine and allocate its costs to the MFS Funds, the
Fund and other accounts and products for purposes of estimating profitability.

After reviewing these and other factors described herein, the Trustees
concluded, within the context of their overall conclusions regarding the
investment advisory agreement, that the advisory fees charged to the Fund
represent reasonable compensation in light of the services being provided by
MFS to the Fund.

In addition, the Trustees considered MFS' resources and related efforts to
continue to retain, attract and motivate capable personnel to serve the Fund.
The Trustees also considered current and developing conditions in the financial
services industry, including the entry into the industry of large and
well-capitalized companies which are spending, and appear to be prepared to
continue to spend, substantial sums to engage personnel and to provide services
to competing investment companies. In this regard, the Trustees also considered
the financial resources of MFS and its ultimate parent, Sun Life Financial Inc.
The Trustees also considered the advantages and possible disadvantages to the
Fund of having an adviser which also serves other investment companies as well
as other accounts.

The Trustees also considered the nature, quality, cost, and extent of
administrative, transfer agency, and distribution services provided to the Fund
by MFS and its affiliates under agreements and plans other than the investment
advisory agreement, including any 12b-1 fees the Fund pays to MFS Fund
Distributors, Inc., an affiliate of MFS. The Trustees also considered the
nature, extent and quality of certain other services MFS performs or arranges
for on the Fund's behalf, including securities lending programs, directed
expense payment programs, class action recovery programs, and MFS' interaction
with third-party service providers, principally custodians and sub-custodians.
The Trustees concluded that the various non-advisory services provided by MFS
and its affiliates on behalf of the Funds were satisfactory.

The Trustees also considered benefits to MFS from the use of the Fund's
portfolio brokerage commissions to pay for investment research (excluding
third-party research, for which MFS pays directly) and various other factors.
Additionally, the Trustees considered so-called "fall-out benefits" to MFS such
as reputational value derived from serving as investment manager to the Fund.

Based on their evaluation of factors that they deemed to be material, including
those factors described above, the Board of Trustees, including a majority of
the independent Trustees, concluded that the Fund's investment advisory
agreement with MFS should be continued for an additional one-year period,
