LETTER FROM THE CHAIRMAN

     A. Keith Brodkin

Dear Shareholders:

After more than six years of expansion, the U.S. economy is experiencing another
year of growth in 1997, although a few signs point to the possibility of a
modest rise in inflation during the year. On the positive side, the pattern of
moderate growth and inflation set over the past few years now seems fairly well
entrenched in the economy and, short of a major international or domestic
crisis, appears to have enough momentum to remain on track for some time. Also,
gains in such important sectors as housing, automobiles, industrial production,
and exports indicate a fair amount of underlying strength in the economy. Some
of that strength was seen in the first quarter, when the U.S. economy grew at an
annualized rate of 5.6% (based on preliminary estimates), a pace that would be
inflationary in the unlikely event that it were to continue. The ongoing
tightness in the labor market could also add some inflationary pressures to the
economy. At the same time, there is some reason for caution as a result of the
continuing high level of consumer debt and rising personal bankruptcies. Given
these somewhat conflicting indicators, we expect real (inflation-adjusted)
growth to revolve around 2% in 1997, with the strength of the first quarter
moderating as we move through the balance of the year.

  In the bond markets, conflicting signals over the strength of the economy have
also created near-term volatility, and the Federal Reserve Board has begun
taking measured steps to control inflation by raising short-term interest rates.
Although we do not expect a repeat of the rapid growth in the first quarter, we
would expect the Fed to raise interest rates at least one more time in reaction
to the economic momentum that was built up during the period. While inflationary
forces largely remained in check in 1996, the continued strength in the labor
market suggests that a pickup in inflation is still possible. At the same time,
the U.S. budget deficit continues to decline and, as a percentage of gross
domestic product, is now approaching 1%, which we consider a positive
development for the bond markets. Although interest rates may remain volatile
over the coming months, we believe that, at current levels, fixed-income markets
remain equitably valued.

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

Respectfully,

/s/ A. Keith Brodkin

A DISCUSSION WITH THE PORTFOLIO MANAGER

[Photo of Geoffrey L. Kurinsky]
     Geoffrey L. Kurinsky

Following a sharp rise in interest rates in early 1996, rates remained
relatively stable over the 12 months ended April 30, 1997. Rates on 10-year
U.S. Treasury securities ended the period at 6.75%, just where they began it
on May 1, 1996. Volatility during this period was also low, with the 10-year
issue trading in a range of 6% to 7%. In this environment, Class A shares of
the Fund provided a total return of 8.99% during this period, Class B shares
8.16%, Class C shares 8.27%, and Class I shares 9.21%. These returns assume
the reinvestment of distributions but exclude the effects of any sales
charges. All classes of shares outperformed the Lehman Brothers Government/
Corporate Bond Index (the Lehman Index), which returned 6.72% over the same
period. The Lehman Index is an unmanaged, market-value-weighted index of U.S.
Treasury and government-agency securities (excluding mortgage-backed
securities) and investment-grade debt obligations of domestic corporations.
The Fund's performance also compared favorably to the 7.42% average return of
other corporate debt "BBB"-rated funds with similar objectives, as tracked by
Lipper Analytical Services, Inc., an independent firm that reports mutual fund
performance.

Q. THE FUND HAS PERFORMED WELL AGAINST ITS BENCHMARK INDICES THIS YEAR. WHAT
DO YOU SEE AS SOME OF THE REASONS FOR THIS PERFORMANCE?
A. The Fund's strong performance resulted from its overweightings in both
investment-grade and high-yield corporate securities, as well as from its 5%
to 10% allocation to nondollar fixed-income securities. The Fund's average 60%
weighting in investment-grade corporates, which is roughly 50% higher than the
average fund in its Lipper peer group, helped the Fund, as this sector's 7.55%
return far outdistanced the 6.37% return of the Lehman Brothers Treasury Index
(an unmanaged index of U.S. Treasury securities). Also, the Fund's average 20%
weighting in high-yield securities, which is about 33% higher than the average
fund in its Lipper peer group, contributed to the strong performance as this
sector recorded a very solid 11.76% total return for the period. The
traditional pattern, in which corporates outperform Treasuries during periods
of strong economic activity, worked again in the past year as the U.S. economy
continues to roll along into its seventh year of economic recovery from the
1990-91 recession. (Principal value and interest on Treasury securities are
guaranteed by the U.S. government if held to maturity.)

Q. SO YOUR WEIGHTINGS IN INVESTMENT-GRADE AND HIGH-YIELD CORPORATES PAID OFF.
WHAT ABOUT SPECIFIC INDUSTRIES?
A. We had significant overweightings in the airline and utility sectors, which
contributed to the strong performance as well. Returns of 8.97% for utilities
and 9.65% for airlines made them the best-performing sectors of the
investment-grade corporate market. The Fund's utility holdings, such as Long
Island Lighting and Commonwealth Edison, are benefiting from prospects for
restructuring that could result in the elimination of much of their
outstanding debt in the next 12 to 18 months. Holdings in the "big three"
airlines -- Delta, American, and United -- benefited from the favorable
pricing environment in the airline business resulting from the strong economy.
These companies were able to generate strong cash flows, which they used to
purchase their outstanding debt securities in the open market, further
improving their credit profiles.

Q. IN GENERAL, HOW WOULD YOU DESCRIBE THE FIXED-INCOME ENVIRONMENT OVER THE
PAST YEAR?
A. It was a traditional "clip-the-coupon" environment like we used to have in
the 1950s and 1960s, when interest rates were much less volatile. With rates
remaining in a relatively tight range, there was little value to add by trying
to anticipate interest-rate movements. Most of the added value came from being
overweighted in the corporate sector and picking the sectors and companies
that we felt would thrive in that environment. We expect a similar environment
to dominate the scene in the coming year as economic activity appears likely
to continue growing and as inflationary pressures remain dormant.

Q. AND HOW IS YOUR VIEW ON THE FIXED-INCOME MARKETS REFLECTED IN THE FUND'S
DURATION, OR INTEREST-RATE SENSITIVITY?
A. The Fund's current duration is six years, roughly equivalent to that of the
average fund in its Lipper peer group. A neutral outlook is consistent with
our view that rates will likely remain in a narrow range through the summer
months.

Q. MORE SPECIFICALLY, WHAT ABOUT THE CORPORATE BOND MARKET? HOW WOULD YOU
DESCRIBE THE ENVIRONMENT THERE?
A. Environments like the current one, that is, ones that feature steady growth
and low inflation, are ideal for the cash flows and credit quality of American
corporations. Despite the fact that the yield premium for corporate securities
is as low today as it has been in 10 years, we believe the corporate asset
class will continue to outperform Treasury and mortgage-backed securities in
the upcoming year.

Q. YOUR BIGGEST WEIGHTING IN THE INVESTMENT-GRADE SECTOR IS A 12% POSITION IN
ELECTRIC UTILITIES. WHAT IS IT THAT YOU LIKE ABOUT THIS SECTOR, AND ARE THERE
ANY UTILITIES YOU PARTICULARLY FAVOR?
A. Under various restructuring plans, many of the utility securities now rated
"BB" by Standard & Poor's will eventually become investment-grade credits.
When securities cross over to investment grade, or move from "BB," the top
high-yield rating, to "BBB," the lowest investment-grade rating, the universe
of buyers expands significantly. There is a limited set of buyers of high-
yield debt, but a vast arena of buyers of investment-grade securities. Our
favorite names within this optimistic scenario include Long Island Lighting,
Niagara Mohawk, and Cleveland Electric.

Q. YOU ALSO HAVE ABOUT 20% OF ASSETS IN HIGH-YIELD CORPORATE BONDS. WHY DO YOU
FEEL COMFORTABLE WITH THIS LEVEL, AND WHAT TYPES OF HIGH-YIELD BONDS ARE IN
THE PORTFOLIO?
A. We like high-yield bonds because the economy is strong and the credit
quality of this sector is improving as well. We focus on the higher end of the
sector, "BB"-rated bonds, and on issues that we believe will cross over to
investment-grade ratings in the next 12 to 18 months. Our largest holdings
include the utilities I mentioned before, as well as Tenet Healthcare, a large
hospital consolidator with an investment-grade credit profile, and Continental
Airlines, which is benefiting from strong pricing trends in the domestic
airline business.

Q. AT THE SAME TIME, YOU'VE CUT THE FUND'S POSITION IN NONDOLLAR MARKETS FROM
APPROXIMATELY 10% OF ASSETS TO 4% IN RECENT MONTHS. WHY?
A. With the tremendous decline in interest rates in Europe throughout 1996, we
feel this sector is less attractive than it was when rates were significantly
higher earlier in 1996. Given all the concern over European monetary
unification, we feel that this sector represents merely fair value.

Q. WE'VE TALKED ABOUT SOME SECTORS AND INDUSTRIES THAT HELPED THE FUND OVER
THE PAST YEAR; NOW, WOULD YOU MIND TALKING ABOUT ANY POSITIONS THAT DID NOT
PERFORM AS WELL AS YOU HOPED?
A. The Fund maintains positions in a couple of companies that have been
adversely affected by the deteriorating pattern in consumer delinquencies.
Advanta Corp., a credit-card company, had a significant pickup in
delinquencies that resulted in an unexpected loss in the first quarter of
1997. At the same time, First Merchants Acceptance Corp. had difficulty with
delinquencies in its auto-loan portfolio. Although we are very concerned about
these trends and talk with the companies frequently, we believe the securities
of both of these institutions represent good value at current prices.

Q. AS YOU LOOK AHEAD, WHAT CHANGES DO YOU SEE IN THE GENERAL ECONOMIC
ENVIRONMENT FOR YOUR MARKET, AND HOW ARE YOU POSITIONING THE FUND FOR THOSE
CHANGES?
A. We are watching the current pace of economic growth and inflation very
closely. While the economy has been growing at a steady pace, we are on the
lookout for signs of an economic slowdown. If we see any of these signs, we
will increase the duration of the portfolio to take advantage of a likely move
to lower interest rates. If we see signs of a protracted slowdown, we will
reduce our exposure to both investment-grade and high-yield corporate
securities. Finally, inflation is the enemy of every bond investor, and it has
failed to show up in the current cycle, despite the strong pace of growth and
resource utilization. If we begin to see signs of inflation, we will reduce
the duration of the portfolio to seek to protect the Fund against the
potential for lower bond prices that could result from higher interest rates.

All results are historical and assume the reinvestment of dividends and
capital gains. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.
Past performance is no guarantee of future results.

Class A share SEC results include the maximum 4.75% sales charge. Class B
share SEC results reflect the applicable contingent deferred sales charge
(CDSC), which declines over six years as follows: 4%, 4%, 3%, 3%, 2%, 1%, 0%.
Class C shares have no initial sales charge but, along with Class B shares,
have higher annual fees and expenses than Class A shares. Class C share
purchases are subject to a 1% CDSC if redeemed within 12 months of purchase.
Class I shares, which became available on January 2, 1997, have no sales
charge or Rule 12b-1 fees and are only available to certain institutional
investors.

Class B and Class C share results include the performance and the operating
expenses (e.g., Rule 12b-1 fees) of the Fund's Class A shares for periods
prior to the commencement of offering of Class B and Class C shares. Because
operating expenses attributable to Class B and Class C shares are higher than
those of Class A shares, Class B and Class C share performance generally would
have been lower than Class A share performance. The Class A share performance
included in the Class B and Class C share SEC performance with CDSC has been
adjusted to reflect the CDSC generally applicable to Class B and Class C
shares rather than the sales charge generally applicable to Class A shares.

Class I share results include the performance and operating expenses (e.g.,
Rule 12b-1 fees) of Class A shares for periods prior to the commencement of
offering of Class I shares. Because operating expenses attributable to Class A
shares are greater than those of Class I shares, Class I share performance
generally would have been higher than Class A share performance. The Class A
share performance included in the Class I share SEC performance has been
adjusted to reflect the fact that Class I shares have no initial sales charge.
These results represent the percentage change in net asset value.

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

NOTES TO FINANCIAL STATEMENTS

(1) Business and Organization
MFS Bond Fund (the Fund) is a diversified series of MFS Series Trust IX (the
Trust).The Trust is organized as a Massachusetts business trust and is
registered under the Investment Company Act of 1940, as amended, as an open-
end management investment company.

(2) Significant Accounting Policies
General - The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
Investments in foreign securities are vulnerable to the effects of changes in
the relative values of the local currency and the U.S. dollar and to the
effects of changes in each country's legal and economic environment.

Investment Valuations - Debt securities (other than short-term obligations
which mature in 60 days or less), including listed issues and forward
contracts are valued on the basis of valuations furnished by dealers or by a
pricing service with consideration to factors such as institutional-size
trading in similar groups of securities, yield, quality, coupon rate,
maturity, type of issue, trading characteristics, and other market data,
without exclusive reliance upon exchange or over-the-counter prices. Short-
term obligations, which mature in 60 days or less, are valued at amortized
cost, which approximates market value. Non-U.S. dollar denominated short-term
obligations are valued at amortized cost as calculated in the base currency
and translated into U.S. dollars at the closing daily exchange rate. Futures
contracts, options, and options on futures contracts listed on commodities
exchanges are valued at closing settlement prices. Over-the-counter options
are valued by brokers through the use of a pricing model which takes into
account closing bond valuations, implied volatility, and short-term repurchase
rates. Equity securities listed on securities exchanges or reported through
the NASDAQ system are valued at last sale prices. Unlisted equity securities
or listed equity securities for which last sale prices are not available are
valued at last quoted bid prices. Securities for which there are no such
quotations or valuations are valued at fair value as determined in good faith
by or at the direction of the Trustees.

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 purchased 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 securities transferred to ensure
that the value, including accrued interest, of the securities under each
repurchase agreement 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, may utilize a joint trading account
for the purpose of entering into one or more repurchase agreements.

Foreign Currency Translation - Investment valuations, other assets, and
liabilities initially expressed in foreign currencies are converted each
business day into U.S. dollars based upon current exchange rates. Purchases
and sales of foreign investments, income, and expenses are converted into U.S.
dollars based upon currency exchange rates prevailing on the respective dates
of such transactions. Gains and losses attributable to foreign currency
exchange rates on sales of securities are recorded for financial statement
purposes as net realized gains and losses on investments. Gains and losses
attributable to foreign exchange rate movements on income and expenses are
recorded for financial statement purposes as foreign currency transaction
gains and losses. That portion of both realized and unrealized gains and
losses on investments that result from fluctuations in foreign currency
exchange rates is not separately disclosed.

Futures Contracts - The Fund may enter into futures contracts for the delayed
delivery of securities, currency, or contracts based on financial indices at a
fixed price on a future date. In entering such contracts, the Fund is required
to deposit either in cash or securities an amount equal to a certain
percentage of the contract amount. Subsequent payments are made or received by
the Fund each day, depending on the daily fluctuations in the value of the
underlying security, and are recorded for financial statement purposes as
unrealized gains or losses by the Fund. The Fund's investment in futures
contracts is designed to hedge against anticipated future changes in interest
or exchange rates or securities prices. Investments in interest rate futures
for purposes other than hedging may be made to modify the duration of the
portfolio without incurring the additional transaction costs involved in
buying and selling the underlying securities. Investments in currency futures
for purposes other than hedging may be made to change the Fund's relative
position in one or more currencies without buying and selling portfolio
assets. Should interest or exchange rates or securities prices move
unexpectedly, the Fund may not achieve the anticipated benefits of the futures
contracts and may realize a loss.

Forward Foreign Currency Exchange Contracts - The Fund may enter into forward
foreign currency exchange contracts for the purchase or sale of a specific
foreign currency at a fixed price on a future date. Risks may arise upon
entering into these contracts from the potential inability of counterparties
to meet the terms of their contracts and from unanticipated movements in the
value of a foreign currency relative to the U.S. dollar. The Fund will enter
into forward contracts for hedging purposes. The Fund may enter into contracts
to deliver or receive foreign currency it will receive from or require for its
normal investment activities. The Fund may also use contracts in a manner
intended to protect foreign currency-denominated securities from declines in
value due to unfavorable exchange rate movements. The forward foreign currency
exchange contracts are adjusted by the daily exchange rate of the underlying
currency and any gains or losses are recorded for financial statement purposes
as unrealized until the contract settlement date.

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

The Fund uses the effective interest method for reporting interest income on
payment-in-kind (PIK) bonds, whereby interest income on PIK bonds is recorded
ratably by the Fund at a constant yield to maturity. Legal fees and other
related expenses incurred to preserve and protect the value of a security
owned are added to the cost of the security; other legal fees are expensed.
Capital infusions, which are generally non-recurring, incurred to protect or
enhance the value of high-yield debt securities, are reported as an addition
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 reported as operating expenses.

Fees Paid Indirectly - The Fund's custodian bank calculates its fee based on
the Fund's average daily net assets. This fee is reduced according to an
expense offset arrangement with State Street Bank, the dividend disbursing
agent, which provides for partial reimbursement of custody fees based on a
formula developed to measure the value of cash deposited with the custodian by
the Fund. This amount is shown as a reduction of expenses on the Statement of
Operations.

Tax Matters and Distributions - The Fund's policy is to comply with the
provisions of the Internal Revenue Code (the Code) applicable to regulated
investment companies and to distribute to shareholders all of its taxable
income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided. The Fund files a tax
return annually using tax accounting methods required under provisions of the
Code which may differ from generally accepted accounting principles, the basis
on which these financial statements are prepared. Accordingly, the amount of
net investment income and net realized gain reported on these financial
statements may differ from that reported on the Fund's tax return and,
consequently, the character of distributions to shareholders reported in the
financial highlights may differ from that reported to shareholders on Form
1099-DIV.

Foreign taxes have been provided for on interest and dividend income earned on
foreign investments in accordance with the applicable country's tax rates and
to the extent unrecoverable are recorded as a reduction of investment income.
Distributions to shareholders are recorded on the ex-dividend date.

The Fund distinguishes between distributions on a tax basis and a financial
reporting basis and requires that only distributions in excess of tax basis
earnings and profits are reported in the financial statements as a tax return
of capital. Differences in the recognition or classification of income between
the financial statements and tax earnings and profits which result in
temporary over-distributions for financial statement purposes, are classified
as distributions in excess of net investment income or accumulated net
realized gains. During the year ended April 30, 1997, $453,565 was
reclassified to accumulated distributions in excess of net investment income
from accumulated net realized loss on investments due to differences between
book and tax accounting for mortgage-backed securities and currency
transactions. This change had no effect on the net assets or net asset value
per share. At April 30, 1997, accumulated net realized loss on investments and
foreign currency transactions under book accounting were different from tax
accounting due to significant temporary differences in accounting for capital
losses.

At April 30, 1997, the Fund, for federal income tax purposes, had a capital
loss carryforward of $12,393,120 which may be applied against any net taxable
realized gains of each succeeding year until the earlier of its utilization or
expiration on April 30, 2003, ($9,844,270) and April 30, 2005, ($2,548,850).

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

(3) Transactions with Affiliates
Investment Adviser - The Fund has an investment advisory agreement with
Massachusetts Financial Services Company (MFS) to provide overall investment
advisory and administrative services, and general office facilities. The
management fee is computed daily and paid monthly at an effective annual rate
of 0.20% of average daily net assets and 2.47% of investment income. The Fund
pays no compensation directly to its Trustees who are officers of the
investment adviser, or to officers of the Fund, all of whom receive
remuneration for their services to the Fund from MFS. Certain officers and
Trustees of the Fund are officers or directors of MFS, MFS Fund Distributors,
Inc. (MFD), and MFS Service Center, Inc. (MFSC). The Fund has an unfunded
defined benefit plan for all of its independent Trustees and Mr. Bailey.
Included in Trustees' compensation is a net periodic pension expense of
$16,704 for the year ended April 30, 1997.

Administrator - Effective March 1, 1997, the Trust has an administrative
services agreement with MFS to provide the Trust with certain financial,
legal, compliance, shareholder communications, and other administrative
services. As a partial reimbursement for the cost of providing these services,
the Fund pays MFS an administrative fee up to 0.015% per annum of the Fund's
average daily net assets, provided that the administrative fee is not assessed
on Fund assets that exceed $3 billion.

Distributor - MFD, a wholly owned subsidiary of MFS, as distributor, received
$134,341 for the year ended April 30, 1997, as its portion of the sales charge
on sales of Class A shares of the Fund.

The Trustees have adopted a distribution plan for Class A, Class B, and Class
C pursuant to Rule 12b-1 of the Investment Company Act of 1940 as follows:

The Fund's distribution plan provides that the Fund will pay MFD up to 0.35%
per annum of its average daily net assets attributable to Class A shares in
order that MFD may pay expenses on behalf of the Fund related to the
distribution and servicing of its shares. These expenses include a service fee
to each securities dealer that enters into a sales agreement with MFD of up to
0.25% per annum of the Fund's average daily net assets attributable to Class A
shares which are attributable to that securities dealer, a distribution fee to
MFD of up to 0.10% per annum of the Fund's average daily net assets
attributable to Class A shares, commissions to dealers, and payments to MFD
wholesalers for sales at or above a certain dollar level, and other such
distribution-related expenses that are approved by the Fund. MFD retains the
service fee for accounts not attributable to a securities dealer which
amounted to $284,694 for the year ended April 30, 1997. The fund is currently
paying distribution fees of 0.05% per annum. Payment of the remaining portion
of the 0.10% per annum Class A distribution fee will commence on such date as
the Trustees of the Trust may determine. Fees incurred under the distribution
plan during the year ended April 30, 1997, were 0.30% of average daily net
assets attributable to Class A shares on an annualized basis.

The Trustees have adopted a distribution plan relating solely to Class B and
Class C shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as
follows:

The Fund's distribution plan provides that the Fund will pay MFD a
distribution fee of 0.75% per annum, and a service fee of up to 0.25% per
annum, of the Fund's average daily net assets attributable to Class B and
Class C shares. MFD will pay to securities dealers that enter into a sales
agreement with MFD all or a portion of the service fee attributable to Class B
and Class C shares, and will pay to such securities dealers all of the
distribution fee attributable to Class C shares. The service fee is intended
to be additional consideration for services rendered by the dealer with
respect to Class B and Class C shares. MFD retains the service fee for
accounts not attributable to a securities dealer, which amounted to $27,709
and $16,107 for Class B and Class C shares, respectively, for the year ended
April 30, 1997. Fees incurred under the distribution plan during the year
ended April 30, 1997, were 1.00% of average daily net assets attributable to
Class B and Class C shares on an annualized basis.

Purchases over $1 million of Class A shares and certain purchases by retirement
plans are subject to a contingent deferred sales charge in the event of a
shareholder redemption within 12 months following such purchase. A contingent
deferred sales charge is imposed on shareholder redemptions of Class B shares in
the event of a shareholder redemption within six years of purchase. A contingent
deferred sales charge is imposed on shareholder redemptions of Class C shares in
the event of a shareholder redemption within twelve months of purchases made on
or after April 1, 1996. MFD receives all contingent deferred sales charges.
Contingent deferred sales charges imposed during the year ended April 30, 1997,
were $38,472, $245,479, and $5,977 for Class A, Class B, and Class C shares,
respectively.

Shareholder Servicing Agent - MFSC, a wholly owned subsidiary of MFS, earns a
fee for its services as shareholder servicing agent. The fee is calculated as
a percentage of the fund's average daily net assets at an effective annual
rate of 0.13%. Prior to January 1, 1997, the fee was calculated as a
percentage of the average daily net assets of each class of shares at an
effective annual rate of up to 0.15%, up to 0.22%, and up to 0.15%
attributable to Class A, Class B, and Class C shares, respectively.

(6) Line of Credit
The Fund entered into an agreement which enables it to participate with other
funds managed by MFS in an unsecured line of credit with a bank which permits
borrowings up to $400 million, collectively. Borrowings may be made to
temporarily finance the repurchase of Fund shares. Interest is charged to each
fund, based on its borrowings, at a rate equal to the bank's base rate. In
addition, a commitment fee, based on the average daily unused portion of the
line of credit, is allocated among the participating funds at the end of each
quarter. The commitment fee allocated to the Fund for the year ended April 30,
1997, was $6,529.

(7) Financial Instruments
The Fund trades financial instruments with off-balance sheet risk in the
normal course of its investing activities in order to manage exposure to
market risks such as interest rates and foreign currency exchange rates. These
financial instruments include forward foreign currency exchange contracts. The
notional or contractual amounts of these instruments represent the investment
the Fund has in particular classes of financial instruments and does not
necessarily represent the amounts potentially subject to risk. The measurement
of the risks associated with these instruments is meaningful only when all
related and offsetting transactions are considered. A summary of obligations
under these financial instruments at April 30, 1997, is as follows:

INDEPENDENT AUDITORS' REPORT

To the Trustees of MFS Series Trust IX and Shareholders of MFS Bond Fund:

We have audited the accompanying statement of assets and liabilities,
including the portfolio of investments, of MFS Bond Fund (one of the series
constituting MFS Series Trust IX) as of April 30, 1997, the related statement
of operations for the year then ended, the statement of changes in net assets
for the years ended April 30, 1997 and 1996, and the financial highlights for
each of the years in the ten-year period ended April 30, 1997. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of the
securities owned at April 30, 1997, by correspondence with the custodian and
brokers; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of MFS Bond Fund at
April 30, 1997, the results of its operations, the changes in its net assets,
and its financial highlights for the respective stated periods in conformity
with generally accepted accounting principles.
