Manning] Dear Shareholders: The past year has been a great example of why investors should keep their eyes on the long term. In 2006 the Dow Jones Industrial Average returned 19%. As of mid-May 2007, it had returned another 8% and continued to reach new highs. But the Dow's upward rise has not been without hiccups. After hitting new records in February, the Dow lost 5.8% between February 20 and March 5, as stocks were sold off around the globe. As we have said before, markets are volatile, and investors should make sure they have an investment plan that can carry them through the peaks and troughs. If you are focused on a long-term investment strategy, the short-term ups and downs of the markets should not necessarily dictate portfolio action on your part. Both the bond and stock markets are cyclical. In our view, investors who remain committed to a long-term plan are more likely to achieve their financial goals. We believe you should not let the headlines guide you in your investment decisions and should be cautious about overreacting to short-term volatility. In any market environment, we believe individual investors are best served by following a three-pronged investment strategy of allocating their holdings across the major asset classes, diversifying within each class, and regularly rebalancing their portfolios to maintain their desired allocations. Of course, these strategies cannot guarantee a profit or protect against a loss. Investing and planning for the long term require 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 Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) June 15, 2007 The opinions expressed in this letter are subject to change, may not be relied upon for investment advice, and no forecasts can be guaranteed.

(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 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 the "AAA"-rating category. Percentages are based on the total market value of investments as of 04/30/07. Percentages are based on net assets as of 04/30/07, unless otherwise noted. The portfolio is actively managed and current holdings may be different. MANAGEMENT REVIEW SUMMARY OF RESULTS For the twelve months ended April 30, 2007, Class A shares of the MFS Bond Fund provided a total return of 8.13%, at net asset value. This compares with a return of 7.34% for the fund's benchmark, the Lehman Brothers U.S. Government/Credit Bond Index (the Lehman Index). CONTRIBUTORS TO PERFORMANCE The fund's larger allocation to corporate bonds and lower exposure to U.S. Treasuries helped relative performance in comparison to the Lehman Index, as corporate bonds outperformed Treasuries throughout the reporting period. Exposure to high yield bonds further enhanced the fund's performance, as these bonds outperformed the overall bond market. Positioning in emerging markets debt also added to the fund's relative return. The fund also enjoyed a favorable yield advantage over the period, generating a higher level of income than the index. On a sector basis, strong performance was seen in the banking and finance and industrial sectors. At the security level the fund held seven companies that were upgraded to investment grade that delivered strong performance. These bonds included utilities firms DPL, Enersis, and Empresa Nacional, office automation and equipment manufacturer Xerox, cable television operator Rogers Cable, metals and mining firm International Steel Group, and medical and health technology and services firm Fisher Scientific. DETRACTORS FROM PERFORMANCE The fund's position in asset-backed securities detracted from overall results. Select mortgage pools were also detractors. Individual securities that were among top relative detractors included casino operator Harrah's(g), and hospital company HCA which were targets of LBOs (leveraged buy outs) during the period. Respectfully, Richard Hawkins Robert Persons Portfolio Manager Portfolio Manager (g) Security was not held in the portfolio at period end. The views expressed in this report are those of the portfolio manager only through the end of the period of the report as stated on the cover and do not necessarily reflect the views of MFS or any other person in the MFS organization.

PERFORMANCE SUMMARY THROUGH 4/30/07 The following chart illustrates a representative class of the fund's historical performance in comparison to its benchmark. Performance results include the deduction of the maximum applicable sales charge and reflect the percentage change in net asset value, including reinvestment of dividends and capital gains distributions. The performance of other share classes will be greater than or less than that of the class depicted below. Benchmark comparisons are unmanaged; do not reflect sales charges, commissions or expenses; and cannot be invested in directly. (See Notes to Performance Summary). PERFORMANCE DATA SHOWN REPRESENTS PAST PERFORMANCE AND IS NO GUARANTEE OF FUTURE RESULTS. INVESTMENT RETURN AND PRINCIPAL VALUE FLUCTUATE SO YOUR SHARES, WHEN SOLD, MAY BE WORTH MORE OR LESS THAN THE ORIGINAL COST; CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN QUOTED.

INDEX DEFINITION Lehman Brothers U.S. Government/Credit Bond Index - measures investment grade debt obligations of the U.S. Treasury and U.S. government agencies, as well as U.S. corporate and foreign debentures and secured notes that meet specified maturity, liquidity, and quality requirements. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Class R shares are available only to existing Class R shareholders and certain other retirement plans. Class I shares are only available to certain eligible investors, and class R1, R2, R3, R4 and R5 shares are only available to certain retirement plans. Performance for classes R, R4 and R5 shares includes the performance of the fund's class A shares for periods prior to their offering. Performance for classes R1, R2 and R3 shares includes the performance of the fund's class B shares for periods prior to their offering. This blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the share class to which it is blended, and lower performance for share classes with lower operating expenses than the share class to which it is blended. Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance results would be less favorable. Please see the prospectus and financial statements for complete details. From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower. EXPENSE TABLE Fund expenses borne by the shareholders during the period, November 1, 2006 through April 30, 2007. 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 November 1, 2006 through April 30, 2007. 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. - -------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period(p) Share Expense Account Value Account Value 11/01/06- Class Ratio 11/01/06 4/30/07 4/30/07 - -------------------------------------------------------------------------------- Actual 0.82% $1,000.00 $1,034.20 $4.14 A ------------------------------------------------------------------------ Hypothetical (h) 0.82% $1,000.00 $1,020.73 $4.11 - -------------------------------------------------------------------------------- Actual 1.52% $1,000.00 $1,030.60 $7.65 B ------------------------------------------------------------------------ Hypothetical (h) 1.52% $1,000.00 $1,017.26 $7.60 - -------------------------------------------------------------------------------- Actual 1.52% $1,000.00 $1,030.60 $7.65 C ------------------------------------------------------------------------ Hypothetical (h) 1.52% $1,000.00 $1,017.26 $7.60 - -------------------------------------------------------------------------------- Actual 0.53% $1,000.00 $1,036.50 $2.68 I ------------------------------------------------------------------------ Hypothetical (h) 0.53% $1,000.00 $1,022.17 $2.66 - -------------------------------------------------------------------------------- Actual 1.02% $1,000.00 $1,034.00 $5.14 R ------------------------------------------------------------------------ Hypothetical (h) 1.02% $1,000.00 $1,019.74 $5.11 - -------------------------------------------------------------------------------- Actual 1.63% $1,000.00 $1,030.90 $8.21 R1 ------------------------------------------------------------------------ Hypothetical (h) 1.63% $1,000.00 $1,016.71 $8.15 - -------------------------------------------------------------------------------- Actual 1.28% $1,000.00 $1,031.90 $6.45 R2 ------------------------------------------------------------------------ Hypothetical (h) 1.28% $1,000.00 $1,018.45 $6.41 - -------------------------------------------------------------------------------- Actual 1.18% $1,000.00 $1,033.20 $5.95 R3 ------------------------------------------------------------------------ Hypothetical (h) 1.18% $1,000.00 $1,018.94 $5.91 - -------------------------------------------------------------------------------- Actual 0.93% $1,000.00 $1,033.70 $4.69 R4 ------------------------------------------------------------------------ Hypothetical (h) 0.93% $1,000.00 $1,020.18 $4.66 - -------------------------------------------------------------------------------- Actual 0.64% $1,000.00 $1,036.00 $3.23 R5 ------------------------------------------------------------------------ Hypothetical (h) 0.64% $1,000.00 $1,021.62 $3.21 - -------------------------------------------------------------------------------- (h) 5% class return per year before expenses.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (1) BUSINESS AND ORGANIZATION MFS Bond Fund (the fund) is a 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 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 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 - 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. 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 an evaluated bid as reported by an independent pricing service. 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. Values 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. 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 and certain types of derivatives. These investments are generally valued at fair value based on information from independent pricing services. 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 securities may often be valued at fair value. 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 September 2006, FASB Statement No. 157, Fair Value Measurements (the "Statement") was issued, and is effective for fiscal years beginning after November 15, 2007 and for all interim periods within those fiscal years. This Statement provides a single definition of fair value, a hierarchy for measuring fair value and expanded disclosures about fair value measurements. Management is evaluating the application of the Statement to the fund, and believes the impact will be limited to expanded disclosures resulting from the adoption of this Statement in the fund's financial statements. In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159 (FAS 159) "The Fair Value Option for Financial Assets and Financial Liabilities - including an amendment of FASB Statement No. 115." FAS 159 permits entities to elect to measure certain financial assets and liabilities at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be reported in earnings at each subsequent reporting date. FAS 159 is effective for fiscal years beginning after November 15, 2007. Management is evaluating the application of the Statement to the fund and its impact on the fund's financial statements, if any, has not been determined. 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 and other funds managed by Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. INFLATION-ADJUSTED DEBT SECURITIES - The fund invests in inflation-adjusted debt securities issued by the U.S. Treasury. The fund may also invest in inflation-adjusted debt securities issued by U.S. Government agencies and instrumentalities other than the U.S. Treasury and by other entities such as U.S. and foreign corporations and foreign governments. The principal value of these debt securities is adjusted by references to changes in the Consumer Price Index or another general price or wage index. These debt securities typically pay a fixed rate of interest, but this fixed rate is applied to the inflation-adjusted principal amount. The principal paid at maturity of the debt security is typically equal to the inflation-adjusted principal amount, or the security's original par value, whichever is greater. Other types of inflation-adjusted securities may use other methods to adjust for other measures of inflation. 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 future contracts and swap agreements. FUTURES CONTRACT - The fund may enter into futures contracts for the delayed delivery of securities or 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 with the broker 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 contract, and are recorded for financial statement purposes as unrealized gains or losses by the fund. Upon entering into such contracts, the fund bears the risk of interest or exchange rates or securities prices moving unexpectedly, in which case, the fund may not achieve the anticipated benefits of the futures contracts and may realize a loss. 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, including accruals of periodic amounts of interest to be paid or received, is recorded as unrealized appreciation or depreciation in the Statement of Operations. A liquidation payment received or made upon early termination is recorded as a realized gain or loss in the Statement of Operations. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with the fund's custodian in connection with these agreements. Risk of loss may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include the possible lack of a liquid market, failure of the counterparty to perform under the terms of the agreements, and unfavorable market movement of the underlying instrument. All swap agreements entered into by the fund with the same counterparty are generally governed by a single master agreement, which provides for the netting of all amounts owed by the parties under the agreement upon the occurrence of an event of default, thereby reducing the credit risk to which such party is exposed. The fund holds a credit default swap in which one party makes a stream of payments based on a fixed percentage applied to the notional amount 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. The fund may enter into credit default swaps to limit or to reduce its risk exposure to defaults of corporate and sovereign issuers or to create direct or synthetic short or long exposure to corporate debt securities or certain sovereign debt securities to which it is not otherwise exposed. INDEMNIFICATIONS - Under the fund's organizational documents, its officers and trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the fund. Additionally, in the normal course of business, the fund enters into agreements with service providers that may contain indemnification clauses. The fund's maximum exposure under these agreements is unknown as this would involve future claims that may be made against the fund that have not yet occurred. 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 may receive proceeds from litigation settlements. Any proceeds received from litigation involving portfolio holdings are reflected in the Statement of Operations in realized gain/loss if the security has been disposed of by the fund or in unrealized gain/loss if the security is still held by the fund. Any other proceeds from litigation not related to portfolio holdings are reflected as other income in the Statement of Operations. 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 year ended April 30, 2007, 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 U.S. 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. The tax character of distributions declared to shareholders is as follows: 4/30/07 4/30/06 Ordinary income (including any short-term capital gains) $67,363,124 $70,873,547 The federal tax cost and the tax basis components of distributable earnings were as follows: AS OF 4/30/07 Cost of investments $1,297,593,363 ------------------------------------------------------------ Gross appreciation 16,004,764 Gross depreciation (17,833,237) ------------------------------------------------------------ Net unrealized appreciation (depreciation) $(1,828,473) Undistributed ordinary income 5,313,714 Capital loss carryforwards (51,406,320) Post-October capital loss deferral (545,434) Other temporary differences (5,651,324) As of April 30, 2007, the fund had capital loss carryforwards available to offset future realized gains. Such losses expire as follows: 4/30/09 $(11,366,948) 4/30/10 (4,472,574) 4/30/11 (26,201,916) 4/30/15 (9,364,882) -------------------------------------- $(51,406,320) 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. On December 22, 2006, the SEC delayed the implementation of the Interpretation for regulated investment companies for an additional six months. 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 evaluated the application of the Interpretation to the fund, and has determined that there is no impact 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. Class 529A, Class 529B, and Class 529C shares closed on March 31, 2007. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund has an investment advisory agreement with MFS to provide overall investment management and related administrative services and facilities to the fund. The management fee is computed daily and paid monthly at the following annual rates: First $1.1 billion of average daily net assets 0.39% Average daily net assets in excess of $1.1 billion 0.38% 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 0.30% of the fund's average daily net assets for the period March 1, 2004 through February 28, 2009. For the year ended April 30, 2007, this waiver amounted to $1,143,129 and is reflected as a reduction of total expenses in the Statement of Operations. The management fee incurred for the year ended April 30, 2007 was equivalent to an annual effective rate of 0.30% of the fund's average daily net assets. DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of MFS, as distributor, received $98,192 and $366 for the year ended April 30, 2007, 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.

(e) The annual effective rates represent actual fees incurred under the distribution plan for the year ended April 30, 2007 based on each class' average daily net assets. Assets attributable to Class A shares sold prior to March 1, 1991 are subject to a service fee of 0.15% annually. 0.05% of the Class A distribution fee is currently being paid by the fund and 0.10% of Class 529A distribution fee was being paid prior to the closure of the share class. Payment of the remaining 0.05% of the Class A distribution fee is not yet in effect and will 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 year ended April 30, 2007, were as follows: AMOUNT Class A $22,611 Class B 291,898 Class C 13,985 The fund has entered into and may from time to time enter into contracts with program managers and other parties which administer the tuition programs through which an investment in the fund's 529 share classes is made. The fund has entered into an agreement with MFD pursuant to which MFD receives an annual fee of up to 0.35% of the average daily net assets attributable to each 529 share class. The fee is based on average daily net assets and is currently established at 0.25% annually of average daily net assets of the fund's 529 share classes. The fee may only be increased with the approval of the Board of Trustees who oversees the fund. The services provided by MFD, or a third party with which MFD contracts, include recordkeeping and tax reporting and account services, as well as services designed to maintain the program's compliance with the Internal Revenue Code and other regulatory requirements. Class 529A, Class 529B, and Class 529C shares closed March 31, 2007. Program manager fees for the year ended April 30, 2007, were as follows: AMOUNT Class 529A $1,154 Class 529B 425 Class 529C 586 ------------------------------------------- Total Program Manager Fees $2,165 SHAREHOLDER SERVICING AGENT - MFS Service Center, Inc. (MFSC), a wholly-owned subsidiary of MFS, receives a fee from the fund for its services as shareholder servicing agent calculated as a percentage of the average daily net assets of the fund as determined periodically under the supervision of the fund's Board of Trustees. For the year ended April 30, 2007, the fee was $1,025,888, which equated to 0.0794% annually of the fund's average daily net assets. MFSC also receives payment from the fund for out-of-pocket expenses, sub-accounting and other shareholder servicing costs which may be paid to affiliated and unaffiliated service providers. For the year ended April 30, 2007, these out-of-pocket expenses, sub-accounting and other shareholder servicing costs amounted to $725,583. The fund may also pay shareholder servicing related costs directly to non-related parties. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to the fund. Under an administrative services agreement, the fund partially reimburses MFS the costs incurred to provide these services. The fund is charged a fixed amount plus a fee based on calendar year average net assets. The fund's annual fixed amount is $17,500. The administrative services fee incurred for the year ended April 30, 2007 was equivalent to an annual effective rate of 0.0182% of the fund's average daily net assets. In addition to the administrative services provided by MFS to the fund as described above, MFS is responsible for providing certain retirement plan 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 year ended April 30, 2007, the fund paid MFS an annual retirement plan administration and services fee up to the following annual percentage rates of each class' average daily net assets: BEGINNING OF PERIOD ANNUAL THROUGH EFFECTIVE EFFECTIVE TOTAL 3/31/07 4/01/07 RATE (g) AMOUNT - -------------------------------------------------------------------------------- Class R1 0.45% 0.35% 0.35% $12,047 Class R2 0.40% 0.25% 0.25% 6,129 Class R3 0.25% 0.15% 0.15% 43,973 Class R4 0.15% 0.15% 0.15% 33,422 Class R5 0.10% 0.10% 0.10% 14,774 - -------------------------------------------------------------------------------- Total Retirement Plan Administration and Services Fees $110,345 (g) Prior to April 1, 2007, MFS had agreed in writing to waive a portion of the retirement plan administration and services fee equal to 0.10% for Class R1, 0.15% for Class R2, and 0.10% for Class R3 shares. This agreement was discontinued on March 31, 2007. On April 1, 2007, the annual retirement plan administration and services fee for Class R1, Class R2, and Class R3 shares was lowered to 0.35%, 0.25%, and 0.15%, respectively. For the year ended April 30, 2007, this waiver amounted to $20,808 and is reflected as a reduction of total expenses in the Statement of Operations. 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 $5,197. The fund also has an unfunded retirement benefit deferral plan for certain independent trustees which resulted in an expense of $4,065. Both amounts are included in independent trustees' compensation for the year ended April 30, 2007. The liability for deferred retirement benefits payable to certain independent trustees under both plans amounted to $99,507 at April 30, 2007, 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 year ended April 30, 2007, the fee paid to Tarantino LLC was $8,254. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $6,557, which is shown as a reduction of total expenses in the Statement of Operations.

(6) LINE OF CREDIT The fund and other funds managed by MFS 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 funds managed by MFS 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 0.30% for the committed line of credit and 0.35% for the uncommitted line of credit. 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 year ended April 30, 2007, the fund's commitment fee and interest expense were $5,068 and $0, respectively, and are included in miscellaneous expense on the Statement of Operations. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To The Trustees of MFS Series Trust IX and the 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 portfolios comprising MFS Series Trust IX (the "Trust")) as of April 30, 2007, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Trust'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 the standards of the Public Company Accounting Oversight Board (United States). 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. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of April 30, 2007, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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 as of April 30, 2007, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

(n) In 2004 and 2005, Mr. Butler provided consulting services to the independent compliance consultant retained by MFS pursuant to its settlement with the SEC concerning market timing and related matters. The terms of that settlement required that compensation and expenses related to the independent compliance consultant be borne exclusively by MFS and, therefore, MFS paid Mr. Butler for the services he rendered to the independent compliance consultant. In 2004 and 2005, MFS paid Mr. Butler a total of $351,119.29. The Trust held a shareholders' meeting in 2005 to elect Trustees, and will hold a shareholders' meeting at least once every five years thereafter, to elect Trustees. Each Trustee (except Mr. Butler and Mr. Uek) has been elected by shareholders and each Trustee and officer holds office until his or her successor is chosen and qualified or until his or her earlier death, resignation, retirement or removal. Messrs. Butler, Gutow, Sherratt and Uek and Ms. Thomsen are members of the Trust's Audit Committee. Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or a subsidiary is the investment adviser or distributor, and, in the case of the officers, with certain affiliates of MFS.

Manning] Dear Shareholders: The past year has been a great example of why investors should keep their eyes on the long term. In 2006 the Dow Jones Industrial Average returned 19%. As of mid-May 2007, it had returned another 8% and continued to reach new highs. But the Dow's upward rise has not been without hiccups. After hitting new records in February, the Dow lost 5.8% between February 20 and March 5, as stocks were sold off around the globe. As we have said before, markets are volatile, and investors should make sure they have an investment plan that can carry them through the peaks and troughs. If you are focused on a long-term investment strategy, the short-term ups and downs of the markets should not necessarily dictate portfolio action on your part. Both the bond and stock markets are cyclical. In our view, investors who remain committed to a long-term plan are more likely to achieve their financial goals. We believe you should not let the headlines guide you in your investment decisions and should be cautious about overreacting to short-term volatility. In any market environment, we believe individual investors are best served by following a three-pronged investment strategy of allocating their holdings across the major asset classes, diversifying within each class, and regularly rebalancing their portfolios to maintain their desired allocations. Of course, these strategies cannot guarantee a profit or protect against a loss. Investing and planning for the long term require 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.

(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 presentation, the bond component includes both accrued interest amounts and the equivalent exposure from any derivative holdings, if applicable, which may result in the investment in a sector of less than 0%. (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 the "AAA"-rating category. Percentages are based on the total market value of investments as of 04/30/07. Percentages are based on net assets as of 04/30/07, unless otherwise noted. The portfolio is actively managed and current holdings may be different. MANAGEMENT REVIEW SUMMARY OF RESULTS For the twelve months ended April 30, 2007, Class A shares of the MFS Limited Maturity Fund provided a total return of 5.65%, at net asset value. This compares with a return of 5.33% for the fund's benchmark, the Lehman Brothers 1-3 Year U.S. Government/Credit Bond Index. CONTRIBUTORS TO PERFORMANCE The portfolio benefited from underweighting U.S. Treasury securities and overweighting corporate bonds as the credit sector outperformed both Treasuries and the benchmark. An overweighted position in the financial services sector was particularly favorable. The portfolio's allocation to corporate bonds also boosted the yield of the portfolio, compared with that of the benchmark, as corporate securities generated higher income than Treasuries. DETRACTORS FROM PERFORMANCE The portfolio's holdings in U.S. Treasury and government agency securities held back relative performance as these bonds typically underperformed the broad benchmark during the reporting period. Positioning in mortgage-backed securities also dampened investment results. Respectfully, James Calmas Portfolio Manager The views expressed in this report are those of the portfolio manager only through the end of the period of the report as stated on the cover and do not necessarily reflect the views of MFS or any other person in the MFS organization.

PERFORMANCE SUMMARY THROUGH 4/30/07 The following chart illustrates a representative class of the fund's historical performance in comparison to its benchmark. Performance results include the deduction of the maximum applicable sales charge and reflect the percentage change in net asset value, including reinvestment of dividends and capital gains distributions. The performance of other share classes will be greater than or less than that of the class depicted below. Benchmark comparisons are unmanaged; do not reflect sales charges, commissions or expenses; and cannot be invested in directly. (See Notes to Performance Summary). PERFORMANCE DATA SHOWN REPRESENTS PAST PERFORMANCE AND IS NO GUARANTEE OF FUTURE RESULTS.

INDEX DEFINITION Lehman Brothers 1-3 Year U.S. Government/Credit Bond Index - measures the short term investment-grade corporate and U.S. government fixed income markets. Securities in the index have a maturity from 1 year up to (but not including) 3 years. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Class R shares are available only to existing Class R shareholders and certain other retirement plans. Class I shares are only available to certain eligible investors, and Class R1, R2, R3, R4, and R5 shares are only available to certain retirement plans. Class 529 shares are only available in conjunction with qualified tuition programs, such as the MFS 529 Savings Plan. There also is an additional fee, which is detailed in the program description, on qualified tuition programs. If this fee was reflected, the performance for Class 529 shares would have been lower. This annual fee is waived for Oregon residents and for those accounts with assets of $25,000 or more. Performance for classes R, R4, R5 and 529A shares includes the performance of the fund's class A shares for periods prior to their offering. Performance for classes R1, R2, R3 and 529B shares includes the performance of the fund's class B shares for periods prior to their offering. Performance for class 529C shares includes the performance of the fund's class C shares for periods prior to their offering. This blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the share class to which it is blended, and lower performance for share classes with lower operating expenses than the share class to which it is blended. Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance results would be less favorable. Please see the prospectus and financial statements for complete details. From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower. EXPENSE TABLE Fund expenses borne by the shareholders during the period, November 1, 2006 through April 30, 2007. 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 November 1, 2006 through April 30, 2007. 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. - -------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period(p) Share Expense Account Value Account Value 11/01/06- Class Ratio 11/01/06 4/30/07 4/30/07 - -------------------------------------------------------------------------------- Actual 0.63% $1,000.00 $1,026.10 $3.16 A ----------------------------------------------------------------------- Hypothetical (h) 0.63% $1,000.00 $1,021.67 $3.16 - -------------------------------------------------------------------------------- Actual 1.40% $1,000.00 $1,022.30 $7.02 B ----------------------------------------------------------------------- Hypothetical (h) 1.40% $1,000.00 $1,017.85 $7.00 - -------------------------------------------------------------------------------- Actual 1.48% $1,000.00 $1,021.80 $7.42 C ----------------------------------------------------------------------- Hypothetical (h) 1.48% $1,000.00 $1,017.46 $7.40 - -------------------------------------------------------------------------------- Actual 0.48% $1,000.00 $1,026.90 $2.41 I ----------------------------------------------------------------------- Hypothetical (h) 0.48% $1,000.00 $1,022.41 $2.41 - -------------------------------------------------------------------------------- Actual 0.88% $1,000.00 $1,024.80 $4.42 R ----------------------------------------------------------------------- Hypothetical (h) 0.88% $1,000.00 $1,020.43 $4.41 - -------------------------------------------------------------------------------- Actual 1.58% $1,000.00 $1,021.30 $7.92 R1 ----------------------------------------------------------------------- Hypothetical (h) 1.58% $1,000.00 $1,016.96 $7.90 - -------------------------------------------------------------------------------- Actual 1.23% $1,000.00 $1,023.10 $6.17 R2 ----------------------------------------------------------------------- Hypothetical (h) 1.23% $1,000.00 $1,018.70 $6.16 - -------------------------------------------------------------------------------- Actual 1.03% $1,000.00 $1,022.50 $5.17 R3 ----------------------------------------------------------------------- Hypothetical (h) 1.03% $1,000.00 $1,019.69 $5.16 - -------------------------------------------------------------------------------- Actual 0.88% $1,000.00 $1,024.80 $4.42 R4 ----------------------------------------------------------------------- Hypothetical (h) 0.88% $1,000.00 $1,020.43 $4.41 - -------------------------------------------------------------------------------- Actual 0.58% $1,000.00 $1,026.40 $2.91 R5 ----------------------------------------------------------------------- Hypothetical (h) 0.58% $1,000.00 $1,021.92 $2.91 - -------------------------------------------------------------------------------- Actual 0.98% $1,000.00 $1,022.70 $4.91 529A ----------------------------------------------------------------------- Hypothetical (h) 0.98% $1,000.00 $1,019.93 $4.91 - -------------------------------------------------------------------------------- Actual 1.60% $1,000.00 $1,021.20 $8.02 529B ----------------------------------------------------------------------- Hypothetical (h) 1.60% $1,000.00 $1,016.86 $8.00 - -------------------------------------------------------------------------------- Actual 1.73% $1,000.00 $1,020.50 $8.67 529C ----------------------------------------------------------------------- Hypothetical (h) 1.73% $1,000.00 $1,016.22 $8.65 - -------------------------------------------------------------------------------- (h) 5% class return per year before expenses.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (1) BUSINESS AND ORGANIZATION MFS Limited Maturity Fund (the fund) is a 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 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 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 - 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. Short-term instruments with a maturity at issuance of 60 days or less may be valued at amortized cost, which approximates market value. Futures contracts are generally valued at last posted settlement price as reported by an independent pricing service on the market on which they are primarily traded. Futures contracts for which there were no trades that day for a particular position are generally valued at the closing bid quotation as reported by an independent pricing service on the market on which such futures contracts are primarily traded. Swaps are generally valued at an evaluated bid as reported by an independent pricing service. 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. Values 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. 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 and certain types of derivatives. These investments are generally valued at fair value based on information from independent pricing services. 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 securities may often be valued at fair value. 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 September 2006, FASB Statement No. 157, Fair Value Measurements (the "Statement") was issued, and is effective for fiscal years beginning after November 15, 2007 and for all interim periods within those fiscal years. This Statement provides a single definition of fair value, a hierarchy for measuring fair value and expanded disclosures about fair value measurements. Management is evaluating the application of the Statement to the fund, and believes the impact will be limited to expanded disclosures resulting from the adoption of this Statement in the fund's financial statements. In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159 (FAS 159) "The Fair Value Option for Financial Assets and Financial Liabilities - including an amendment of FASB Statement No. 115." FAS 159 permits entities to elect to measure certain financial assets and liabilities at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be reported in earnings at each subsequent reporting date. FAS 159 is effective for fiscal years beginning after November 15, 2007. Management is evaluating the application of the Statement to the fund and its impact on the fund's financial statements, if any, has not been determined. 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 and other funds managed by Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. 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 futures contracts and swap agreements. FUTURES CONTRACTS - The fund may enter into futures contracts for the delayed delivery of securities or 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 with the broker 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 contract, and are recorded for financial statement purposes as unrealized gains or losses by the fund. Upon entering into such contracts, the fund bears the risk of interest or exchange rates or securities prices moving unexpectedly, in which case, the fund may not achieve the anticipated benefits of the futures contracts and may realize a loss. 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, including accruals of periodic amounts of interest to be paid or received, is recorded as unrealized appreciation or depreciation in the Statement of Operations. A liquidation payment received or made upon early termination is recorded as a realized gain or loss in the Statement of Operations. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with the fund's custodian in connection with these agreements. Risk of loss may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include the possible lack of a liquid market, failure of the counterparty to perform under the terms of the agreements, and unfavorable market movement of the underlying instrument. All swap agreements entered into by the fund with the same counterparty are generally governed by a single master agreement, which provides for the netting of all amounts owed by the parties under the agreement upon the occurrence of an event of default, thereby reducing the credit risk to which such party is exposed. The fund holds a credit default swap in which one party makes a stream of payments based on a fixed percentage applied to the notional amount 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. The fund may enter into credit default swaps to limit or to reduce its risk exposure to defaults of corporate and sovereign issuers or to create direct or synthetic short or long exposure to corporate debt securities or certain sovereign debt securities to which it is not otherwise exposed. INDEMNIFICATIONS - Under the fund's organizational documents, its officers and trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the fund. Additionally, in the normal course of business, the fund enters into agreements with service providers that may contain indemnification clauses. The fund's maximum exposure under these agreements is unknown as this would involve future claims that may be made against the fund that have not yet occurred. 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 may receive proceeds from litigation settlements. Any proceeds received from litigation involving portfolio holdings are reflected in the Statement of Operations in realized gain/loss if the security has been disposed of by the fund or in unrealized gain/loss if the security is still held by the fund. Any other proceeds from litigation not related to portfolio holdings are reflected as other income in the Statement of Operations. 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 year ended April 30, 2007, 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 U.S. 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 and amortization and accretion of debt securities. The tax character of distributions declared to shareholders is as follows: 4/30/07 4/30/06 Ordinary income (including any short-term capital gains) $31,206,219 $29,202,936 The federal tax cost and the tax basis components of distributable earnings were as follows: AS OF APRIL 30, 2007 Cost of investments $761,991,033 ---------------------------------------------------------- Gross appreciation 1,294,714 Gross depreciation (13,782,255) ---------------------------------------------------------- Net unrealized appreciation (depreciation) $(12,487,541) Undistributed ordinary income $3,140,705 Capital loss carryforwards (94,527,086) Post-October capital loss deferral (5,764,068) Other temporary differences (2,852,042) As of April 30, 2007, the fund had capital loss carryforwards available to offset future realized gains. Such losses expire as follows: April 30, 2008 $(9,838,280) April 30, 2009 (2,874,797) April 30, 2011 (18,880,791) April 30, 2012 (15,641,631) April 30, 2013 (18,655,874) April 30, 2014 (16,764,678) April 30, 2015 (11,871,035) ---------------------------------------------- $(94,527,086) The availability of a portion of the capital loss carryforwards, which were acquired on November 17, 2006 in connection with the MFS Government Limited Maturity Fund merger, may be limited in a given year. 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. On December 22, 2006, the SEC delayed the implementation of the Interpretation for regulated investment companies for an additional six months. 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 evaluated the application of the Interpretation to the fund, and has determined that there is no impact 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 management and related administrative services and facilities to the fund. The management fee is computed daily and paid monthly at an annual rate of 0.40% 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 0.25% of the fund's average daily net assets for the period March 1, 2004 through February 28, 2009. For the year ended April 30, 2007, this waiver amounted to $1,028,902 and is reflected as a reduction of total expenses in the Statement of Operations. The management fee incurred for the year ended April 30, 2007 was equivalent to an annual effective rate of 0.25% of the fund's average daily net assets. DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of MFS, as distributor, received $18,713 and $831 for the year ended April 30, 2007, 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.

(e) The annual effective rates represent actual fees incurred under the distribution plan for the year ended April 30, 2007 based on each class' average daily net assets. 0.15% of the Class A service fee is currently being paid by the fund. Payment of the remaining 0.10% of the Class A service fee is not yet in effect and will be implemented on such date as the fund's Board of Trustees may determine. Payment of the 0.10% annual Class A distribution fee is not yet in effect and will be implemented on such date as the fund's Board of Trustees may determine. 0.10% of the Class 529A service fee is currently being waived under a written waiver arrangement through September 1, 2007. For the year ended April 30, 2007, this waiver amounted to $3,359 and is reflected as a reduction of total expenses in the Statement of Operations. 0.10% of the Class 529A distribution fee is currently being paid by the fund. Payment of the remaining 0.15% of the Class 529A distribution fee is not yet in effect and will be implemented on such date as the fund's Board of Trustees may determine. For one year from the date of sale of Class B and Class 529B shares, assets attributable to such Class B and Class 529B shares are subject to the 0.25% annual Class B and Class 529B service fee. On assets attributable to all other Class B and Class 529B shares, 0.15% of the Class B and Class 529B service fee is currently in effect and the remaining portion of the Class B and Class 529B service fee is not in effect but may be implemented on such date as the fund's Board of Trustees may determine. 0.10% of the Class R and 0.10% of the Class R3 distribution fee is currently being waived under a written waiver arrangement through September 1, 2007. For the year ended April 30, 2007, this waiver amounted to $3,276 and is reflected as a reduction of total expenses in the Statement of Operations. Certain Class A, Class C and Class 529C shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within 12 months of purchase. Class B and Class 529B 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 year ended April 30, 2007, were as follows: AMOUNT Class A $2,248 Class B $271,815 Class C $6,244 Class 529B $77 Class 529C $15 The fund has entered into and may from time to time enter into contracts with program managers and other parties which administer the tuition programs through which an investment in the fund's 529 share classes is made. The fund has entered into an agreement with MFD pursuant to which MFD receives an annual fee of up to 0.35% of the average daily net assets attributable to each 529 share class. The fee is based on average daily net assets and is currently established at 0.25% annually of average daily net assets of the fund's 529 share classes.

This agreement was discontinued on March 31, 2007.

This amount is included in independent trustees' compensation for the year ended April 30, 2007. The liability for deferred retirement benefits payable to certain retired independent trustees amounted to $14,175 at April 30, 2007, and is included in payable for independent trustees' compensation.

Please see the fund's prospectus for details. 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 Conservative Allocation Fund was the owner of record of approximately 19% of the value of outstanding voting shares. In addition, the MFS Lifetime 2010 Fund and the MFS Lifetime Retirement Income 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 funds managed by MFS 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 funds managed by MFS 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 0.30% for the committed line of credit and 0.35% for the uncommitted line of credit. 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 year ended April 30, 2007, the fund's commitment fee and interest expense were $2,416 and $0, respectively, and are included in miscellaneous expense on the Statement of Operations. (7) ACQUISITIONS On November 20, 2006, the fund acquired all of the assets and liabilities of MFS Government Limited Maturity Fund as of the close of business on November 17, 2006. The acquisition was accomplished by a tax-free exchange of 33,345,698 shares of the fund (valued at $213,722,879) for all of the assets and liabilities of MFS Government Limited Maturity Fund. MFS Government Limited Maturity Fund then distributed the shares that it received from the fund to its shareholders. MFS Government Limited Maturity Fund's net assets on that date were $213,722,879, including $2,066,339 of unrealized depreciation, $5,943 of accumulated net investment loss, and $44,340,025 of accumulated net realized loss on investments. The aggregate net assets of the fund after the acquisition were $801,912,388. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Trustees of MFS Series Trust IX and the Shareholders of MFS Limited Maturity Fund: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of MFS Limited Maturity Fund (one of the portfolios comprising MFS Series Trust IX (the "Trust")) as of April 30, 2007, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Trust'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 the standards of the Public Company Accounting Oversight Board (United States). 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. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of April 30, 2007, by correspondence with the custodian. 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 Limited Maturity Fund as of April 30, 2007, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

The terms of that settlement required that compensation and expenses related to the independent compliance consultant be borne exclusively by MFS and, therefore, MFS paid Mr. Butler for the services he rendered to the independent compliance consultant. In 2004 and 2005, MFS paid Mr. Butler a total of $351,119.29. The Trust held a shareholders' meeting in 2005 to elect Trustees, and will hold a shareholders' meeting at least once every five years thereafter, to elect Trustees.

Manning] Dear Shareholders: The past year has been a great example of why investors should keep their eyes on the long term. In 2006 the Dow Jones Industrial Average returned 19%. As of mid-May 2007, it had returned another 8% and continued to reach new highs. But the Dow's upward rise has not been without hiccups. After hitting new records in February, the Dow lost 5.8% between February 20 and March 5, as stocks were sold off around the globe. As we have said before, markets are volatile, and investors should make sure they have an investment plan that can carry them through the peaks and troughs. If you are focused on a long-term investment strategy, the short-term ups and downs of the markets should not necessarily dictate portfolio action on your part. Both the bond and stock markets are cyclical. In our view, investors who remain committed to a long-term plan are more likely to achieve their financial goals. We believe you should not let the headlines guide you in your investment decisions and should be cautious about overreacting to short-term volatility. In any market environment, we believe individual investors are best served by following a three-pronged investment strategy of allocating their holdings across the major asset classes, diversifying within each class, and regularly rebalancing their portfolios to maintain their desired allocations. Of course, these strategies cannot guarantee a profit or protect against a loss. Investing and planning for the long term require 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 Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) June 15, 2007 The opinions expressed in this letter are subject to change, may not be relied upon for investment advice, and no forecasts can be guaranteed. PORTFOLIO COMPOSITION PORTFOLIO STRUCTURE (i) Bonds 100.0% TOP FIVE INDUSTRIES (i) Healthcare Revenue - Hospitals 13.1% ------------------------------------------------ State & Local Agencies 11.3% ------------------------------------------------ General Obligations - General Purpose 10.6% ------------------------------------------------ Utilities - Municipal Owned 8.6% ------------------------------------------------ Water & Sewer Utility Revenue 8.1% ------------------------------------------------ CREDIT QUALITY OF BONDS (r) AAA 55.1% ------------------------------------------------ AA 10.9% ------------------------------------------------ A 17.2% ------------------------------------------------ BBB 16.5% ------------------------------------------------ BB 0.1% ------------------------------------------------ Not Rated 0.2% ------------------------------------------------ PORTFOLIO FACTS Average Duration (d)(i) 3.7 ------------------------------------------------ Average Life (i)(m) 4.9 yrs ------------------------------------------------ Average Maturity (i)(m) 7.3 yrs ------------------------------------------------ Average Credit Quality of Rated Securities (long-term) (a) AA ------------------------------------------------ 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 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 the "AAA"-rating category. Percentages are based on the total market value of investments as of 04/30/07. Percentages are based on net assets as of 04/30/07, unless otherwise noted. The portfolio is actively managed and current holdings may be different. MANAGEMENT REVIEW SUMMARY OF RESULTS For the twelve months ended April 30, 2007, Class A shares of the MFS Municipal Limited Maturity Fund provided a total return of 3.83%, at net asset value. In comparison, the fund's benchmarks, the Lehman Brothers 3-Year Municipal Bond Index (3-Year Index) and the Lehman Brothers 5-Year Municipal Bond Index (5-Year Index), returned 3.97% and 4.21%, respectively. FACTORS THAT AFFECTED PERFORMANCE Relative to the 3-Year Index, the fund's longer duration(d) stance was a detractor from performance. In the area of credit quality, the fund's overweighted positioning in higher-quality "AAA"-rated(s) bonds also held back relative results as lower-quality bonds outperformed higher-quality bonds over the investment period. On the positive side, positioning along the middle portion of the yield curve(y) (represented by bonds with durations of 4- to 8- years), helped performance relative to the 3-Year Index. Our overweighting in "BBB"-rated securities, which outperformed the overall benchmark, and strong security selection in the credit enhanced and general obligation sectors also boosted results. Relative to the 5-Year Index, our positioning on the short end of the yield curve (represented by bonds with durations of 0- to 4- years) detracted from relative performance. Our underweighting in the transportation sector also held back results. During the reporting period, security selection in the general obligation and credit enhanced sectors contributed to performance relative to the 5-Year Index. Respectfully, Geoffrey Schechter Portfolio Manager (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. (s) Bonds rated "BBB", "Baa", or higher are considered investment grade; bonds rated "BB", "Ba", or below are considered non-investment grade. The primary source for bond quality ratings is Moody's Investors Service. If not available, ratings by Standard & Poor's are used, else ratings by Fitch, Inc. For securities which are not rated by any of the three agencies, the security is considered Not Rated. (y) A yield curve graphically depicts the yields of different maturity bonds of the same credit quality and type. A normal yield curve is upward sloping, with short term-rates lower than long term rates. The views expressed in this report are those of the portfolio manager only through the end of the period of the report as stated on the cover and do not necessarily reflect the views of MFS or any other person in the MFS organization. These views are subject to change at any time based on market or other conditions, and MFS disclaims any responsibility to update such views.

PERFORMANCE SUMMARY THROUGH 4/30/07 The following chart illustrates a representative class of the fund's historical performance in comparison to its benchmark. Performance results include the deduction of the maximum applicable sales charge and reflect the percentage change in net asset value, including reinvestment of dividends and capital gains distributions. The performance of other share classes will be greater than or less than that of the class depicted below. Benchmark comparisons are unmanaged; do not reflect sales charges, commissions or expenses; and cannot be invested in directly. (See Notes to Performance Summary). PERFORMANCE DATA SHOWN REPRESENTS PAST PERFORMANCE AND IS NO GUARANTEE OF FUTURE RESULTS. INVESTMENT RETURN AND PRINCIPAL VALUE FLUCTUATE SO YOUR SHARES, WHEN SOLD, MAY BE WORTH MORE OR LESS THAN THE ORIGINAL COST; CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN QUOTED. FOR MOST RECENT MONTH-END PERFORMANCE, PLEASE VISIT MFS.COM.

INDEX DEFINITIONS Lehman Brothers 3-Year Municipal Bond Index - a market-value-weighted index representative of the medium-term (2 to 4 years) tax-exempt bond market. Lehman Brothers 5-Year Municipal Bond Index - a market-value-weighted index representative of the medium-term (4 to 6 years) tax-exempt bond market. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance results would be less favorable. Please see the prospectus and financial statements for complete details. A portion of income may be subject to state, federal, and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax. From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower. EXPENSE TABLE Fund expenses borne by the shareholders during the period, November 1, 2006 through April 30, 2007. 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 November 1, 2006 through April 30, 2007. 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. - -------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period(p) Share Expense Account Value Account Value 11/01/06- Class Ratio 11/01/06 4/30/07 4/30/07 - -------------------------------------------------------------------------------- A Actual 0.67% $1,000.00 $1,011.60 $3.34 ------------------------------------------------------------------------ Hypothetical (h) 0.67% $1,000.00 $1,021.47 $3.36 - -------------------------------------------------------------------------------- B Actual 1.44% $1,000.00 $1,007.80 $7.17 ------------------------------------------------------------------------ Hypothetical (h) 1.44% $1,000.00 $1,017.65 $7.20 - -------------------------------------------------------------------------------- C Actual 1.53% $1,000.00 $1,007.30 $7.61 ------------------------------------------------------------------------ Hypothetical (h) 1.53% $1,000.00 $1,017.21 $7.65 - -------------------------------------------------------------------------------- (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.

(s) From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower. (t) Total returns do not include any applicable sales charges. (z) The fund applied a change in estimate for amortization of premium on certain debt securities in the current year that resulted in an increase of less than $0.01 per share to net investment income, a decrease of less than $0.01 per share to net realized and unrealized gain (loss) on investments, and an increase of 0.06% to the net investment income ratio for each class for the year ended April 30, 2007. The change in estimate had no impact on net assets, net asset value per share or total return of each class. SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (1) BUSINESS AND ORGANIZATION MFS Municipal Limited Maturity Fund (the fund) is a 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 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. 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. 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 an evaluated bid as reported by an independent pricing service. 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. Values 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. 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 and certain types of derivatives. These investments are generally valued at fair value based on information from independent pricing services. 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 securities may often be valued at fair value. 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 September 2006, FASB Statement No. 157, Fair Value Measurements (the "Statement") was issued, and is effective for fiscal years beginning after November 15, 2007 and for all interim periods within those fiscal years. This Statement provides a single definition of fair value, a hierarchy for measuring fair value and expanded disclosures about fair value measurements. Management is evaluating the application of the Statement to the fund, and believes the impact will be limited to expanded disclosures resulting from the adoption of this Statement in the fund's financial statements. In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159 (FAS 159) "The Fair Value Option for Financial Assets and Financial Liabilities - including an amendment of FASB Statement No. 115." FAS 159 permits entities to elect to measure certain financial assets and liabilities at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be reported in earnings at each subsequent reporting date. FAS 159 is effective for fiscal years beginning after November 15, 2007. Management is evaluating the application of the Statement to the fund and its impact on the fund's financial statements, if any, has not been determined. 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, including accruals of periodic amounts of interest to be paid or received, is recorded as unrealized appreciation or depreciation in the Statement of Operations. A liquidation payment received or made upon early termination is recorded as a realized gain or loss in the Statement of Operations. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with the fund's custodian in connection with these agreements. Risk of loss may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include the possible lack of a liquid market, failure of the counterparty to perform under the terms of the agreements, and unfavorable market movement of the underlying instrument. All swap agreements entered into by the fund with the same counterparty are generally governed by a single master agreement, which provides for the netting of all amounts owed by the parties under the agreement upon the occurrence of an event of default, thereby reducing the credit risk to which such party is exposed. The fund holds interest rate swap agreements which involve the periodic exchange of cash flows, such as the exchange of fixed rate interest payments for floating rate interest payments based on a notional principal amount. The interest rates may be based on a specific financial index or the exchange of two distinct floating rate payments. The fund may enter into an interest rate swap in order to manage its exposure to interest rate fluctuations. INDEMNIFICATIONS - Under the fund's organizational documents, its officers and trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the fund. Additionally, in the normal course of business, the fund enters into agreements with service providers that may contain indemnification clauses. The fund's maximum exposure under these agreements is unknown as this would involve future claims that may be made against the fund that have not yet occurred. 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. Any proceeds received from litigation involving portfolio holdings are reflected in the Statement of Operations in realized gain/loss if the security has been disposed of by the fund or in unrealized gain/loss if the security is still held by the fund. Any other proceeds from litigation not related to portfolio holdings are reflected as other income in the Statement of Operations. 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. As a result of a change in estimate for the amortization of premium and accretion of discount on debt securities, interest has been increased with a corresponding reduction to net unrealized appreciation (depreciation) in the amount of $114,545. 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 year ended April 30, 2007, 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 U.S. 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. The tax character of distributions declared to shareholders is as follows: 4/30/07 4/30/06 Tax-exempt income $5,337,300 $6,751,638 The federal tax cost and the tax basis components of distributable earnings were as follows: AS OF 4/30/07 Cost of investments $155,139,903 ------------------------------------------------------------- Gross appreciation $1,999,248 Gross depreciation (279,503) ------------------------------------------------------------- Net unrealized appreciation (depreciation) $1,719,745 Undistributed tax-exempt income $673,630 Capital loss carryforwards (3,499,249) Post-October capital loss deferral (156,370) Other temporary differences (435,316) As of April 30, 2007, the fund had capital loss carryforwards available to offset future realized gains. Such losses expire as follows: 4/30/08 $(383,520) 4/30/09 (516,819) 4/30/11 (159,222) 4/30/12 (277,860) 4/30/13 (789,744) 4/30/14 (625,131) 4/30/15 (746,953) -------------------------------------------------- $(3,499,249) 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. On December 22, 2006, the SEC delayed the implementation of the Interpretation for regulated investment companies for an additional six months. 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 evaluated the application of the Interpretation to the fund, and has determined that there is no impact 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 management and related administrative services and facilities to the fund. The management fee is computed daily and paid monthly at an annual rate of 0.40% 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 0.25% of the fund's average daily net assets for the period March 1, 2004 through February 28, 2009. For the year ended April 30, 2007, this waiver amounted to $265,712 and is reflected as a reduction of total expenses in the Statement of Operations. The management fee incurred for the year ended April 30, 2007 was equivalent to an annual effective rate of 0.25% of the fund's average daily net assets. DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of MFS, as distributor, received $5,530 for the year ended April 30, 2007, 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. Distribution Fee Plan Table: TOTAL ANNUAL DISTRIBUTION DISTRIBUTION SERVICE DISTRIBUTION EFFECTIVE AND SERVICE FEE RATE FEE RATE PLAN(d) RATE(e) FEE Class A 0.10% 0.25% 0.35% 0.15% $191,755 Class B 0.75% 0.25% 1.00% 0.91% 173,062 Class C 0.75% 0.25% 1.00% 1.00% 302,271 - -------------------------------------------------------------------------------------------------------- Total Distribution and Service Fees $667,088 (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 year ended April 30, 2007 based on each class' average daily net assets. 0.15% of the Class A service fee is currently being paid by the fund. Payment of the remaining 0.10% of the Class A service fee is not yet in effect and will be implemented on such date as the fund's Board of Trustees may determine. Payment of the 0.10% annual Class A distribution fee is not yet in effect and will be implemented on such date as the fund's Board of Trustees may determine. 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. On assets attributable to all other Class B shares, 0.15% of the Class B service fee is currently in effect and the remaining portion of the Class B service fee is not 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 year ended April 30, 2007, were as follows: AMOUNT Class A $2,208 Class B $78,583 Class C $2,154 SHAREHOLDER SERVICING AGENT - MFS Service Center, Inc. (MFSC), a wholly-owned subsidiary of MFS, receives a fee from the fund for its services as shareholder servicing agent calculated as a percentage of the average daily net assets of the fund as determined periodically under the supervision of the fund's Board of Trustees. For the year ended April 30, 2007, the fee was $143,054, which equated to 0.0808% annually of the fund's average daily net assets. MFSC also receives payment from the fund for out-of-pocket expenses, sub-accounting and other shareholder servicing costs which may be paid to affiliated and unaffiliated service providers. For the year ended April 30, 2007, these out-of-pocket expenses, sub-accounting and other shareholder servicing costs amounted to $80,125. The fund may also pay shareholder servicing related costs directly to non-related parties. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to the fund. Under an administrative services agreement, the fund partially reimburses MFS the costs incurred to provide these services. The fund is charged a fixed amount plus a fee based on calendar year average net assets. The fund's annual fixed amount is $17,500. The administrative services fee incurred for the year ended April 30, 2007 was equivalent to an annual effective rate of 0.0228% 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 $411. This amount is included in independent trustees' compensation for the year ended April 30, 2007. The liability for deferred retirement benefits payable to certain retired independent trustees amounted to $8,070 at April 30, 2007, 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 year ended April 30, 2007, the fee paid to Tarantino LLC was $1,132. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $908, 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. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $15,551,498 and $63,017,120, respectively. (5) SHARES OF BENEFICIAL INTEREST The fund's Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. Transactions in fund shares were as follows: YEAR ENDED YEAR ENDED 4/30/07 4/30/06 SHARES AMOUNT SHARES AMOUNT Shares sold Class A 2,793,311 $21,515,998 6,104,516 $47,257,249 Class B 38,653 296,625 155,719 1,202,304 Class C 234,405 1,803,662 671,442 5,210,773 - --------------------------------------------------------------------------------------------------- 3,066,369 $23,616,285 6,931,677 $53,670,326 Shares issued to shareholders in reinvestment of distributions Class A 402,418 $3,099,656 508,658 $3,933,594 Class B 36,457 280,449 47,060 363,434 Class C 46,496 358,449 56,873 440,156 - --------------------------------------------------------------------------------------------------- 485,371 $3,738,554 612,591 $4,737,184 Shares reacquired Class A (7,633,112) $(58,688,130) (9,873,897) $(76,311,859) Class B (1,155,329) (8,877,165) (1,324,049) (10,229,791) Class C (1,724,503) (13,293,210) (1,729,415) (13,389,529) - --------------------------------------------------------------------------------------------------- (10,512,944) $(80,858,505) (12,927,361) $(99,931,179) Net change Class A (4,437,383) $(34,072,476) (3,260,723) $(25,121,016) Class B (1,080,219) (8,300,091) (1,121,270) (8,664,053) Class C (1,443,602) (11,131,099) (1,001,100) (7,738,600) - --------------------------------------------------------------------------------------------------- (6,961,204) $(53,503,666) (5,383,093) $(41,523,669) Effective May 1, 2006, the sale of Class B shares of the fund have been suspended except in certain circumstances. Please see the fund's prospectus for details. (6) LINE OF CREDIT The fund and other funds managed by MFS 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 funds managed by MFS 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 0.30% for the committed line of credit and 0.35% for the uncommitted line of credit. 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 year ended April 30, 2007, the fund's commitment fee and interest expense were $585 and $0, respectively, and are included in miscellaneous expense on the Statement of Operations. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To The Trustees of MFS Series Trust IX and the Shareholders of MFS Municipal Limited Maturity Fund: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of MFS Municipal Limited Maturity Fund (one of the portfolios comprising MFS Series Trust IX (the "Trust")) as of April 30, 2007, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Trust'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 the standards of the Public Company Accounting Oversight Board (United States). 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. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of April 30, 2007, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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 Municipal Limited Maturity Fund as of April 30, 2007, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

(n) In 2004 and 2005, Mr. Butler provided consulting services to the independent compliance consultant retained by MFS pursuant to its settlement with the SEC concerning market timing and related matters. The terms of that settlement required that compensation and expenses related to the independent compliance consultant be borne exclusively by MFS and, therefore, MFS paid Mr. Butler for the services he rendered to the independent compliance consultant. In 2004 and 2005, MFS paid Mr. Butler a total of $351,119.29. The Trust held a shareholders' meeting in 2005 to elect Trustees, and will hold a shareholders' meeting at least once every five years thereafter, to elect Trustees. Each Trustee (except Mr. Butler and Mr. Uek) has been elected by shareholders and each Trustee and officer holds office until his or her successor is chosen and qualified or until his or her earlier death, resignation, retirement or removal. Messrs. Butler, Gutow, Sherratt and Uek and Ms. Thomsen are members of the Trust's Audit Committee. Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or a subsidiary is the investment adviser or distributor, and, in the case of the officers, with certain affiliates of MFS. As of January 1, 2007, the Trustees served as board members of 97 funds within the MFS Family of Funds.

Manning] Dear Shareholders: The past year has been a great example of why investors should keep their eyes on the long term. In 2006 the Dow Jones Industrial Average returned 19%. As of mid-May 2007, it had returned another 8% and continued to reach new highs. But the Dow's upward rise has not been without hiccups. After hitting new records in February, the Dow lost 5.8% between February 20 and March 5, as stocks were sold off around the globe. As we have said before, markets are volatile, and investors should make sure they have an investment plan that can carry them through the peaks and troughs. If you are focused on a long-term investment strategy, the short-term ups and downs of the markets should not necessarily dictate portfolio action on your part. Both the bond and stock markets are cyclical. In our view, investors who remain committed to a long-term plan are more likely to achieve their financial goals. We believe you should not let the headlines guide you in your investment decisions and should be cautious about overreacting to short-term volatility. In any market environment, we believe individual investors are best served by following a three-pronged investment strategy of allocating their holdings across the major asset classes, diversifying within each class, and regularly rebalancing their portfolios to maintain their desired allocations. Of course, these strategies cannot guarantee a profit or protect against a loss. Investing and planning for the long term require 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 Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) June 15, 2007 The opinions expressed in this letter are subject to change, may not be relied upon for investment advice, and no forecasts can be guaranteed.

(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 presentation, the bond component includes both accrued interest amounts and the equivalent exposure from any derivative holdings, if applicable, which may result in the investment in a sector of less than 0%. (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 the "AAA"-rating category. Percentages are based on the total market value of investments as of 04/30/07. Percentages are based on net assets as of 04/30/07, unless otherwise noted. The portfolio is actively managed and current holdings may be different. MANAGEMENT REVIEW SUMMARY OF RESULTS For the twelve months ended April 30, 2007, Class A shares of the MFS Intermediate Investment Grade Bond Fund provided a total return of 6.55%, at net asset value. This compares with a return of 6.59% for the fund's benchmark, the Lehman Brothers Intermediate U.S. Government/Credit Bond Index. DETRACTORS FROM PERFORMANCE The portfolio's holdings in asset-backed securities held back performance relative to the benchmark as these bonds typically underperformed the overall benchmark over the reporting period. Some of the portfolio's holdings in mortgage-backed securities also detracted from relative results. CONTRIBUTORS TO PERFORMANCE The portfolio benefited from underweighting U.S. Treasury securities and overweighting corporate bonds as the credit sector outperformed both Treasuries and the benchmark. An overweighted position and security selection of bonds in the financial services sector were particularly favorable. The portfolio's allocation to corporate bonds also boosted the yield of the portfolio, compared with that of the benchmark, as corporate securities generated higher income than Treasuries. Respectfully, James Calmas Portfolio Manager The views expressed in this report are those of the portfolio manager only through the end of the period of the report as stated on the cover and do not necessarily reflect the views of MFS or any other person in the MFS organization. These views are subject to change at any time based on market or other conditions, and MFS disclaims any responsibility to update such views. These views may not be relied upon as investment advice or an indication of trading intent on behalf of any MFS portfolio. References to specific securities are not recommendations of such securities, and may not be representative of any MFS portfolio's current or future investments. PERFORMANCE SUMMARY THROUGH 4/30/07 The following chart illustrates a representative class of the fund's historical performance in comparison to its benchmark. Performance results include the deduction of the maximum applicable sales charge and reflect the percentage change in net asset value, including reinvestment of dividends and capital gains distributions. The performance of other share classes will be greater than or less than that of the class depicted below. Benchmark comparisons are unmanaged; do not reflect sales charges, commissions or expenses; and cannot be invested in directly. (See Notes to Performance Summary). PERFORMANCE DATA SHOWN REPRESENTS PAST PERFORMANCE AND IS NO GUARANTEE OF FUTURE RESULTS. INVESTMENT RETURN AND PRINCIPAL VALUE FLUCTUATE SO YOUR SHARES, WHEN SOLD, MAY BE WORTH MORE OR LESS THAN THE ORIGINAL COST; CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN QUOTED.

INDEX DEFINITION Lehman Brothers Intermediate U.S. Government/Credit Bond Index - measures investment grade debt obligations of the U.S. Treasury and U.S. government agencies, as well as U.S. corporate and foreign debentures and secured notes with maturity from 1 year up to (but not including) 10 years. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Class R shares are available only to existing Class R shareholders and certain other retirement plans. Class I shares are only available to certain eligible investors, and class R1, R2, R3, R4 and R5 shares are only available to certain retirement plans. Performance for share classes offered after class A shares includes the performance of the fund's class A shares for periods prior to their offering. This blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the share class to which it is blended, and lower performance for share classes with lower operating expenses than the share class to which it is blended. Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance results would be less favorable. Please see the prospectus and financial statements for complete details. From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower. EXPENSE TABLE Fund expenses borne by the shareholders during the period, November 1, 2006 through April 30, 2007. 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 November 1, 2006 through April 30, 2007. 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. - -------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period(p) Share Expense Account Value Account Value 11/01/06- Class Ratio 11/01/06 4/30/07 4/30/07 - -------------------------------------------------------------------------------- Actual 0.64% $1,000.00 $1,026.40 $3.22 A ------------------------------------------------------------------------ Hypothetical (h) 0.64% $1,000.00 $1,021.62 $3.21 - -------------------------------------------------------------------------------- Actual 1.49% $1,000.00 $1,023.10 $7.47 B ------------------------------------------------------------------------- Hypothetical (h) 1.49% $1,000.00 $1,017.41 $7.45 - -------------------------------------------------------------------------------- Actual 1.49% $1,000.00 $1,022.10 $7.47 C ------------------------------------------------------------------------ Hypothetical (h) 1.49% $1,000.00 $1,017.41 $7.45 - -------------------------------------------------------------------------------- Actual 0.49% $1,000.00 $1,028.20 $2.46 I ------------------------------------------------------------------------ Hypothetical (h) 0.49% $1,000.00 $1,022.36 $2.46 - -------------------------------------------------------------------------------- Actual 0.99% $1,000.00 $1,025.70 $4.97 R ------------------------------------------------------------------------ Hypothetical (h) 0.99% $1,000.00 $1,019.89 $4.96 - -------------------------------------------------------------------------------- Actual 1.59% $1,000.00 $1,022.60 $7.97 R1 ------------------------------------------------------------------------ Hypothetical (h) 1.59% $1,000.00 $1,016.91 $7.95 - -------------------------------------------------------------------------------- Actual 1.24% $1,000.00 $1,024.40 $6.22 R2 ------------------------------------------------------------------------ Hypothetical (h) 1.24% $1,000.00 $1,018.65 $6.21 - -------------------------------------------------------------------------------- Actual 1.14% $1,000.00 $1,023.90 $5.72 R3 ------------------------------------------------------------------------ Hypothetical (h) 1.14% $1,000.00 $1,019.14 $5.71 - -------------------------------------------------------------------------------- Actual 0.89% $1,000.00 $1,025.10 $4.47 R4 ------------------------------------------------------------------------ Hypothetical (h) 0.89% $1,000.00 $1,020.38 $4.46 - -------------------------------------------------------------------------------- Actual 0.59% $1,000.00 $1,027.70 $2.97 R5 ------------------------------------------------------------------------ Hypothetical (h) 0.59% $1,000.00 $1,021.87 $2.96 - -------------------------------------------------------------------------------- (h) 5% class return per year before expenses.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (1) BUSINESS AND ORGANIZATION MFS Intermediate Investment Grade Bond Fund (the fund) is a 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 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 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 - 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. Short-term instruments with a maturity at issuance of 60 days or less may be valued at amortized cost, which approximates market value. Futures contracts are generally valued at last posted settlement price as reported by an independent pricing service on the market on which they are primarily traded. Futures contracts for which there were no trades that day for a particular position are generally valued at the closing bid quotation as reported by an independent pricing service on the market on which such futures contracts are primarily traded. Swaps are generally valued at an evaluated bid as reported by an independent pricing service. 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. Values 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. 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 and certain types of derivatives. These investments are generally valued at fair value based on information from independent pricing services. 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 securities may often be valued at fair value. 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 September 2006, FASB Statement No. 157, Fair Value Measurements (the "Statement") was issued, and is effective for fiscal years beginning after November 15, 2007 and for all interim periods within those fiscal years. This Statement provides a single definition of fair value, a hierarchy for measuring fair value and expanded disclosures about fair value measurements. Management is evaluating the application of the Statement to the fund, and believes the impact will be limited to expanded disclosures resulting from the adoption of this Statement in the fund's financial statements. In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159 (FAS 159) "The Fair Value Option for Financial Assets and Financial Liabilities - including an amendment of FASB Statement No. 115." FAS 159 permits entities to elect to measure certain financial assets and liabilities at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be reported in earnings at each subsequent reporting date. FAS 159 is effective for fiscal years beginning after November 15, 2007. Management is evaluating the application of the Statement to the fund and its impact on the fund's financial statements, if any, has not been determined. 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 and other funds managed by 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 futures contracts and swap agreements. FUTURES CONTRACTS - The fund may enter into futures contracts for the delayed delivery of securities or 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 with the broker 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 contract, and are recorded for financial statement purposes as unrealized gains or losses by the fund. Upon entering into such contracts, the fund bears the risk of interest or exchange rates or securities prices moving unexpectedly, in which case, the fund may not achieve the anticipated benefits of the futures contracts and may realize a loss. 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, including accruals of periodic amounts of interest to be paid or received, is recorded as unrealized appreciation or depreciation in the Statement of Operations. A liquidation payment received or made upon early termination is recorded as a realized gain or loss in the Statement of Operations. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with the fund's custodian in connection with these agreements. Risk of loss may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include the possible lack of a liquid market, failure of the counterparty to perform under the terms of the agreements, and unfavorable market movement of the underlying instrument. All swap agreements entered into by the fund with the same counterparty are generally governed by a single master agreement, which provides for the netting of all amounts owed by the parties under the agreement upon the occurrence of an event of default, thereby reducing the credit risk to which such party is exposed. The fund holds a credit default swap in which one party makes a stream of payments based on a fixed percentage applied to the notional amount 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. The fund may enter into credit default swaps to limit or to reduce its risk exposure to defaults of corporate and sovereign issuers or to create direct or synthetic short or long exposure to corporate debt securities or certain sovereign debt securities to which it is not otherwise exposed. INDEMNIFICATIONS - Under the fund's organizational documents, its officers and trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the fund. Additionally, in the normal course of business, the fund enters into agreements with service providers that may contain indemnification clauses. The fund's maximum exposure under these agreements is unknown as this would involve future claims that may be made against the fund that have not yet occurred. 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 may receive proceeds from litigation settlements. Any proceeds received from litigation involving portfolio holdings are reflected in the Statement of Operations in realized gain/loss if the security has been disposed of by the fund or in unrealized gain/loss if the security is still held by the fund. Any other proceeds from litigation not related to portfolio holdings are reflected as other income in the Statement of Operations. 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 year ended April 30, 2007, 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 U.S. 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. The tax character of distributions declared to shareholders is as follows: 4/30/07 4/30/06 Ordinary income (including any short-term capital gains) $20,284,890 $15,678,415 The federal tax cost and the tax basis components of distributable earnings were as follows: AS OF 4/30/07 Cost of investments $436,181,204 --------------------------------------------------------- Gross appreciation 1,692,894 Gross depreciation (6,987,972) --------------------------------------------------------- Net unrealized appreciation (depreciation) $(5,295,078) Undistributed ordinary income 2,139,560 Capital loss carryforwards (6,960,191) Post-October capital loss deferral (781,249) Other temporary differences (1,805,808) As of April 30, 2007, the fund had capital loss carryforwards available to offset future realized gains. Such losses expire as follows: 4/30/12 $(108,693) 4/30/13 (1,464,107) 4/30/14 (1,670,568) 4/30/15 (3,716,823) ------------------------------------------------ $(6,960,191) 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. On December 22, 2006, the SEC delayed the implementation of the Interpretation for regulated investment companies for an additional six months. 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 evaluated the application of the Interpretation to the fund, and has determined that there is no impact 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 MFS to provide overall investment management and related administrative services and facilities to the fund. The management fee is computed daily and paid monthly at an annual rate of 0.50% 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 0.30% of the fund's average daily net assets for the period March 1, 2004 through February 28, 2009. For the year ended April 30, 2007, this waiver amounted to $807,597 and is reflected as a reduction of total expenses in the Statement of Operations. The investment adviser has agreed in writing to pay a portion of the fund's operating expenses, exclusive of management, distribution and service, retirement plan administration and services, and certain other fees and expenses, such that operating expenses do not exceed 0.25% annually of the fund's average daily net assets. This written agreement will continue through August 31, 2007 unless changed or rescinded by the fund's Board of Trustees. For the year ended April 30, 2007, the fund's actual operating expenses did not exceed the limit and therefore, the investment adviser did not pay any portion of the fund's expenses. DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of MFS, as distributor, received $2,850 for the year ended April 30, 2007, 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.

(e) The annual effective rates represent actual fees incurred under the distribution plan for the year ended April 30, 2007, based on each class' average daily net assets. 0.10% of the Class A service fee is currently being waived under a written waiver arrangement through September 1, 2007. For the year ended April 30, 2007, this waiver amounted to $77,830 and is reflected as a reduction of total expenses in the Statement of Operations. Assets attributable to Class B shares sold prior to May 1, 2006 are subject to the 0.25% annual Class B service fee. Assets attributable to Class B shares are currently subject to a Class B service fee of 0.15% annually. The remaining portion of the Class B service fee is not in effect on such assets but may be implemented on such date as the fund's Board of Trustees may determine. 0.10% of the Class A distribution fee is currently being waived under a written waiver arrangement through September 1, 2007. For the year ended April 30, 2007, this waiver amounted to $77,830 and is reflected as a reduction of total expenses in the Statement of Operations. 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 year ended April 30, 2007, were as follows: AMOUNT Class A $12 Class B 22,514 Class C 336 SHAREHOLDER SERVICING AGENT - MFS Service Center, Inc. (MFSC), a wholly-owned subsidiary of MFS, receives a fee from the fund for its services as shareholder servicing agent calculated as a percentage of the average daily net assets of the fund as determined periodically under the supervision of the fund's Board of Trustees. For the year ended April 30, 2007, the fee was $317,579, which equated to 0.0786% annually of the fund's average daily net assets. MFSC also receives payment from the fund for out-of-pocket expenses, sub-accounting and other shareholder servicing costs which may be paid to affiliated and unaffiliated service providers. For the year ended April 30, 2007, these out-of-pocket expenses, sub-accounting and other shareholder servicing costs amounted to $82,434. The fund may also pay shareholder servicing related costs directly to non-related parties. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to the fund. Under an administrative services agreement, the fund partially reimburses MFS the costs incurred to provide these services. The fund is charged a fixed amount plus a fee based on calendar year average net assets. The fund's annual fixed amount is $17,500. The administrative services fee incurred for the year ended April 30, 2007, was equivalent to an annual effective rate of 0.020% of the fund's average daily net assets. In addition to the administrative services provided by MFS to the fund as described above, MFS is responsible for providing certain retirement plan 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 year ended April 30, 2007, the fund paid MFS an annual retirement plan administration and services fee up to the following annual percentage rates of each class' average daily net assets: BEGINNING OF PERIOD EFFECTIVE ANNUAL TOTAL THROUGH 3/31/07 4/1/07 EFFECTIVE RATE (g) AMOUNT Class R1 0.45% 0.35% 0.35% $ 282 Class R2 0.40% 0.25% 0.25% 796 Class R3 0.25% 0.15% 0.15% 1,094 Class R4 0.15% 0.15% 0.15% 248 Class R5 0.10% 0.10% 0.10% 53 - ----------------------------------------------------------------------------------------------------- Total Retirement Plan Administration and Services Fees $2,473 (g) Prior to April 1, 2007, MFS had agreed in writing to waive a portion of the retirement plan administration and services fee equal to 0.10% for Class R1, 0.15% for Class R2, and 0.10% for Class R3 shares. This agreement was discontinued on March 31, 2007. On April 1, 2007, the annual retirement plan administration and services fee for Class R1, Class R2, and Class R3 shares was lowered to 0.35%, 0.25%, and 0.15%, respectively. For the year ended April 30, 2007, the waiver amounted to $747 and is reflected as a reduction of total expenses in the Statement of Operations. 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. 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 year ended April 30, 2007, the fee paid to Tarantino LLC was $2,589. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $2,035, 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.

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 Conservative Allocation Fund and MFS Moderate Allocation Fund were the owners of record of approximately 25% and 51%, respectively, of the value of outstanding voting shares. In addition, the MFS Lifetime Retirement Income Fund, the MFS Lifetime 2010 Fund, and the MFS Lifetime 2020 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 funds managed by MFS 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 funds managed by MFS 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 0.30% for the committed line of credit and 0.35% for the uncommitted line of credit. 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 year ended April 30, 2007, the fund's commitment fee and interest expense were $1,693 and $0, respectively, and are included in miscellaneous expense on the Statement of Operations. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To The Trustees of MFS Series Trust IX and the Shareholders of MFS Intermediate Investment Grade Bond Fund: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of MFS Intermediate Investment Grade Bond Fund (one of the portfolios comprising MFS Series Trust IX (the "Trust")) as of April 30, 2007, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Trust'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 the standards of the Public Company Accounting Oversight Board (United States). 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. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of April 30, 2007, by correspondence with the custodian. 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 Intermediate Investment Grade Bond Fund as of April 30, 2007, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

(n) In 2004 and 2005, Mr. Butler provided consulting services to the independent compliance consultant retained by MFS pursuant to its settlement with the SEC concerning market timing and related matters. The terms of that settlement required that compensation and expenses related to the independent compliance consultant be borne exclusively by MFS and, therefore, MFS paid Mr. Butler for the services he rendered to the independent compliance consultant. In 2004 and 2005, MFS paid Mr. Butler a total of $351,119.29. The Trust held a shareholders' meeting in 2005 to elect Trustees, and will hold a shareholders' meeting at least once every five years thereafter, to elect Trustees. Each Trustee (except Mr. Butler and Mr. Uek) has been elected by shareholders and each Trustee and officer holds office until his or her successor is chosen and qualified or until his or her earlier death, resignation, retirement or removal. Messrs. Butler, Gutow, Sherratt and Uek and Ms. Thomsen are members of the Trust's Audit Committee. Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or a subsidiary is the investment adviser or distributor, and, in the case of the officers, with certain affiliates of MFS. As of January 1, 2007, the Trustees served as board members of 97 funds within the MFS Family of Funds.

Manning] Dear Shareholders: The past year has been a great example of why investors should keep their eyes on the long term. In 2006 the Dow Jones Industrial Average returned 19%. As of mid-May 2007, it had returned another 8% and continued to reach new highs. But the Dow's upward rise has not been without hiccups. After hitting new records in February, the Dow lost 5.8% between February 20 and March 5, as stocks were sold off around the globe. As we have said before, markets are volatile, and investors should make sure they have an investment plan that can carry them through the peaks and troughs. If you are focused on a long-term investment strategy, the short-term ups and downs of the markets should not necessarily dictate portfolio action on your part. Both the bond and stock markets are cyclical. In our view, investors who remain committed to a long-term plan are more likely to achieve their financial goals. We believe you should not let the headlines guide you in your investment decisions and should be cautious about overreacting to short-term volatility. In any market environment, we believe individual investors are best served by following a three-pronged investment strategy of allocating their holdings across the major asset classes, diversifying within each class, and regularly rebalancing their portfolios to maintain their desired allocations. Of course, these strategies cannot guarantee a profit or protect against a loss. Investing and planning for the long term require 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 Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) June 15, 2007 The opinions expressed in this letter are subject to change, may not be relied upon for investment advice, and no forecasts can be guaranteed.

(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 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 the "AAA"-rating category. Percentages are based on the total market value of investments as of 04/30/07. Percentages are based on net assets as of 04/30/07, unless otherwise noted. The portfolio is actively managed and current holdings may be different. MANAGEMENT REVIEW SUMMARY OF RESULTS For the twelve months ended April 30, 2007, Class A shares of the MFS Research Bond Fund provided a total return of 7.08%, at net asset value. This compares with a return of 7.35% for the fund's benchmark, the Lehman Brothers U.S. Aggregate Bond Index (the Lehman Index). DETRACTORS FROM PERFORMANCE The fund's overweighted position in U.S. Treasuries detracted from results relative to the Lehman Index. The fund's holdings of asset-backed securities were also a drag on performance. Our underweighted position in the strong- performing mortgage-backed securities sector hurt relative results over the reporting period. This positioning was due in large part to the negative convexity(c) of the asset class. CONTRIBUTORS TO PERFORMANCE The fund's positioning in corporate bonds added to relative results. Other areas that contributed to performance included our holdings of high yield bonds and emerging market debt which the index does not own. The fund also benefited from holding higher-yielding securities than the benchmark. Respectfully, Robert Persons Michael Roberge Jeffrey Wakelin Portfolio Manager Portfolio Manager Portfolio Manager (c) Convexity is a measure of the curvature of the price-yield curve. The combination of duration and convexity provides a better approximation of a bond's sensitivity to changes in interest rates. Duration provides a first order approximation of how much a bond price will drop with rising interest rates or rise with falling interest rates. Positive convexity implies an additional positive impact for all interest rate movements; negative convexity implies an additional negative impact. The views expressed in this report are those of the portfolio managers only through the end of the period of the report as stated on the cover and do not necessarily reflect the views of MFS or any other person in the MFS organization. These views are subject to change at any time based on market or other conditions, and MFS disclaims any responsibility to update such views.

PERFORMANCE SUMMARY THROUGH 4/30/07 The following chart illustrates a representative class of the fund's historical performance in comparison to its benchmark. Performance results include the deduction of the maximum applicable sales charge and reflect the percentage change in net asset value, including reinvestment of dividends and capital gains distributions. The performance of other share classes will be greater than or less than that of the class depicted below. Benchmark comparisons are unmanaged; do not reflect sales charges, commissions or expenses; and cannot be invested in directly. (See Notes to Performance Summary).

It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Class I and W shares are only available to certain eligible investors, and Class R, R1, R2, R3, R4 and R5 shares are only available to certain retirement plans. Class W shares are intended for purchase only through fee-based wrap programs sponsored by financial intermediaries, such as brokerage firms and investment advisers, which have entered into an agreement with the fund's distributor to offer Class W shares to their wrap program clients. Class 529 shares are only available in conjunction with qualified tuition programs, such as the MFS 529 Savings Plan. There also is an additional fee, which is detailed in the program description, on qualified tuition programs. If this fee was reflected, the performance for Class 529 shares would have been lower. This annual fee is waived for Oregon residents and for those accounts with assets of $25,000 or more. Performance for share classes offered after class A shares includes the performance of the fund's class A shares for periods prior to their offering. This blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the share class to which it is blended, and lower performance for share classes with lower operating expenses than the share class to which it is blended. Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance results would be less favorable. Please see the prospectus and financial statements for complete details. From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower. EXPENSE TABLE Fund expenses borne by the shareholders during the period, November 1, 2006 through April 30, 2007. 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 November 1, 2006 through April 30, 2007. 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. - -------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period(p) Share Expense Account Value Account Value 11/01/06- Class Ratio 11/01/06 4/30/07 4/30/07 - -------------------------------------------------------------------------------- A Actual 0.70% $1,000.00 $1,026.90 $3.52 ------------------------------------------------------------------------ Hypothetical (h) 0.70% $1,000.00 $1,021.32 $3.51 - -------------------------------------------------------------------------------- B Actual 1.55% $1,000.00 $1,022.60 $7.77 ------------------------------------------------------------------------ Hypothetical (h) 1.55% $1,000.00 $1,017.11 $7.75 - -------------------------------------------------------------------------------- C Actual 1.55% $1,000.00 $1,021.60 $7.77 ------------------------------------------------------------------------ Hypothetical (h) 1.55% $1,000.00 $1,017.11 $7.75 - -------------------------------------------------------------------------------- I Actual 0.55% $1,000.00 $1,027.70 $2.77 ------------------------------------------------------------------------ Hypothetical (h) 0.55% $1,000.00 $1,022.07 $2.76 - -------------------------------------------------------------------------------- W Actual 0.65% $1,000.00 $1,026.10 $3.27 ------------------------------------------------------------------------ Hypothetical (h) 0.65% $1,000.00 $1,021.57 $3.26 - -------------------------------------------------------------------------------- R Actual 1.05% $1,000.00 $1,025.10 $5.27 ------------------------------------------------------------------------ Hypothetical (h) 1.05% $1,000.00 $1,019.59 $5.26 - -------------------------------------------------------------------------------- R1 Actual 1.65% $1,000.00 $1,022.10 $8.27 ------------------------------------------------------------------------ Hypothetical (h) 1.65% $1,000.00 $1,016.61 $8.25 - -------------------------------------------------------------------------------- R2 Actual 1.30% $1,000.00 $1,023.90 $6.52 ---------------------------------------------------------------------------- Hypothetical (h) 1.30% $1,000.00 $1,018.35 $6.51 - -------------------------------------------------------------------------------- R3 Actual 1.20% $1,000.00 $1,024.40 $6.02 ---------------------------------------------------------------------------- Hypothetical (h) 1.20% $1,000.00 $1,018.84 $6.01 - -------------------------------------------------------------------------------- R4 Actual 0.95% $1,000.00 $1,025.60 $4.77 ---------------------------------------------------------------------------- Hypothetical (h) 0.95% $1,000.00 $1,020.08 $4.76 - -------------------------------------------------------------------------------- R5 Actual 0.64% $1,000.00 $1,027.20 $3.22 ---------------------------------------------------------------------------- Hypothetical (h) 0.64% $1,000.00 $1,021.62 $3.21 - -------------------------------------------------------------------------------- 529A Actual 1.05% $1,000.00 $1,025.10 $5.27 ------------------------------------------------------------------------ Hypothetical (h) 1.05% $1,000.00 $1,019.59 $5.26 - -------------------------------------------------------------------------------- 529B Actual 1.80% $1,000.00 $1,021.30 $9.02 ------------------------------------------------------------------------ Hypothetical (h) 1.80% $1,000.00 $1,015.87 $9.00 - -------------------------------------------------------------------------------- 529C Actual 1.80% $1,000.00 $1,021.30 $9.02 ------------------------------------------------------------------------ Hypothetical (h) 1.80% $1,000.00 $1,015.87 $9.00 - -------------------------------------------------------------------------------- (h) 5% class return per year before expenses.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (1) BUSINESS AND ORGANIZATION MFS Research Bond Fund (the fund) is a 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 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 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 - 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. Short-term instruments with a maturity at issuance of 60 days or less may be valued at amortized cost, which approximates market value. Futures contracts are generally valued at last posted settlement price as reported by an independent pricing service on the market on which they are primarily traded. Futures contracts for which there were no trades that day for a particular position are generally valued at the closing bid quotation as reported by an independent pricing service on the market on which such futures contracts are primarily traded. Swaps are generally valued at an evaluated bid as reported by an independent pricing service. 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. Values 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. 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 and certain types of derivatives. These investments are generally valued at fair value based on information from independent pricing services. 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 securities may often be valued at fair value. 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 September 2006, FASB Statement No. 157, Fair Value Measurements (the "Statement") was issued, and is effective for fiscal years beginning after November 15, 2007 and for all interim periods within those fiscal years. This Statement provides a single definition of fair value, a hierarchy for measuring fair value and expanded disclosures about fair value measurements. Management is evaluating the application of the Statement to the fund, and believes the impact will be limited to expanded disclosures resulting from the adoption of this Statement in the fund's financial statements. In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159 (FAS 159) "The Fair Value Option for Financial Assets and Financial Liabilities - including an amendment of FASB Statement No. 115." FAS 159 permits entities to elect to measure certain financial assets and liabilities at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be reported in earnings at each subsequent reporting date. FAS 159 is effective for fiscal years beginning after November 15, 2007. Management is evaluating the application of the Statement to the fund and its impact on the fund's financial statements, if any, has not been determined. REPURCHASE AGREEMENTS - The trust may enter into repurchase agreements with institutions that the trust's investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The trust requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the trust to obtain those securities in the event of a default under the repurchase agreement. The trust 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 trust under each such repurchase agreement. The trust and other funds managed by Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. INFLATION-ADJUSTED DEBT SECURITIES - The fund invests in inflation-adjusted debt securities issued by the U.S. Treasury. The fund may also invest in inflation-adjusted debt securities issued by U.S. Government agencies and instrumentalities other than the U.S. Treasury and by other entities such as U.S. and foreign corporations and foreign governments. The principal value of these debt securities is adjusted by references to changes in the Consumer Price Index or another general price or wage index. These debt securities typically pay a fixed rate of interest, but this fixed rate is applied to the inflation-adjusted principal amount. The principal paid at maturity of the debt security is typically equal to the inflation-adjusted principal amount, or the security's original par value, whichever is greater. Other types of inflation-adjusted securities may use other methods to adjust for other measures of inflation. 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 futures contracts and swap agreements. FUTURES CONTRACTS - The fund may enter into futures contracts for the delayed delivery of securities or 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 with the broker 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 contract, and are recorded for financial statement purposes as unrealized gains or losses by the fund. Upon entering into such contracts, the fund bears the risk of interest or exchange rates or securities prices moving unexpectedly, in which case, the fund may not achieve the anticipated benefits of the futures contracts and may realize a loss. 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, including accruals of periodic amounts of interest to be paid or received, is recorded as unrealized appreciation or depreciation in the Statement of Operations. A liquidation payment received or made upon early termination is recorded as a realized gain or loss in the Statement of Operations. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with the fund's custodian in connection with these agreements. Risk of loss may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include the possible lack of a liquid market, failure of the counterparty to perform under the terms of the agreements, and unfavorable market movement of the underlying instrument. All swap agreements entered into by the fund with the same counterparty are generally governed by a single master agreement, which provides for the netting of all amounts owed by the parties under the agreement upon the occurrence of an event of default, thereby reducing the credit risk to which such party is exposed. The fund holds a credit default swap in which one party makes a stream of payments based on a fixed percentage applied to the notional amount 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. The fund may enter into credit default swaps to limit or to reduce its risk exposure to defaults of corporate and sovereign issuers or to create direct or synthetic short or long exposure to corporate debt securities or certain sovereign debt securities to which it is not otherwise exposed. 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. INDEMNIFICATIONS - Under the fund's organizational documents, its officers and trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the fund. Additionally, in the normal course of business, the fund enters into agreements with service providers that may contain indemnification clauses. The fund's maximum exposure under these agreements is unknown as this would involve future claims that may be made against the fund that have not yet occurred. 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, facility fees, consent fees, and prepayment fees. These fees are recorded on an accrual basis as income in the accompanying financial statements. The fund may receive proceeds from litigation settlements. Any proceeds received from litigation involving portfolio holdings are reflected in the Statement of Operations in realized gain/loss if the security has been disposed of by the fund or in unrealized gain/loss if the security is still held by the fund. Any other proceeds from litigation not related to portfolio holdings are reflected as other income in the Statement of Operations. 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 year ended April 30, 2007, 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 U.S. 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, wash sale loss deferrals, and derivative transactions. The tax character of distributions declared to shareholders is as follows: 4/30/07 4/30/06 Ordinary income (including any short-term capital gains) $100,785,733 $80,722,565 Long-term capital gain -- 1,332,915 - ----------------------------------------------------------------------- Total distributions $100,785,733 $82,055,480 The federal tax cost and the tax basis components of distributable earnings were as follows: AS OF 4/30/07 Cost of investments $2,251,457,550 ------------------------------------------------------------- Gross appreciation 14,472,037 Gross depreciation (20,270,120) ------------------------------------------------------------- Net unrealized appreciation (depreciation) $(5,798,083) Undistributed ordinary income 8,397,725 Capital loss carryforwards (41,538,272) Post-October capital loss deferral (4,008,183) Other temporary differences (10,009,906) As of April 30, 2007, the fund had capital loss carryforwards available to offset future realized gains. Such losses expire as follows: 4/30/14 $(10,425,624) 4/30/15 (31,112,648) --------------------------------------------------------- $(41,538,272) 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. On December 22, 2006, the SEC delayed the implementation of the Interpretation for regulated investment companies for an additional six months. 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 evaluated the application of the Interpretation to the fund, and has determined that there is no impact 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 management and related administrative services and facilities to the fund. The management fee is computed daily and paid monthly at an annual rate of 0.50% of the fund's average daily net assets. The investment adviser has agreed in writing to reduce its management fee to 0.35% of average daily net assets. This written agreement may be rescinded only upon consent of the fund's Board of Trustees. This management fee reduction amounted to $3,007,679, which is shown as a reduction of total expenses in the Statement of Operations. The management fee incurred for the year ended April 30, 2007 was equivalent to an annual effective rate of 0.35% of the fund's average daily net assets. The investment adviser has voluntarily agreed to pay a portion of the fund's operating expenses, exclusive of management, distribution and service, retirement plan administration and services, program manager, and certain other fees and expenses, such that operating expenses do not exceed 0.20% annually of the fund's average daily net assets. This agreement may be rescinded at any time. For the year ended April 30, 2007, this reduction amounted to $286,797 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 $88,400 and $272 for the year ended April 30, 2007, 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.

(e) The annual effective rates represent actual fees incurred under the distribution plan for the year ended April 30, 2007 based on each class' average daily net assets. 0.10% of the Class A and 0.10% of the Class 529A service fee is currently being waived under a written waiver arrangement through September 1, 2007. For the year ended April 30, 2007, this waiver amounted to $1,006,999 and is reflected as a reduction of total expenses in the Statement of Operations. Assets attributable to Class B shares sold prior to May 1, 2006 are subject to the 0.25% annual Class B service fee. Assets attributable to Class B shares are currently subject to a Class B service fee of 0.15% annually. The remaining portion of the Class B service fee is not in effect on such assets but may be implemented on such date as the fund's Board of Trustees may determine. 0.10% of the Class 529A distribution fee is currently being paid by the fund. Payment of the remaining 0.15% of the Class 529A distribution fee is not yet in effect and will be implemented on such date as the fund's Board of Trustees may determine. 0.10% of the Class A distribution fee is currently being waived under a written waiver arrangement through September 1, 2007. For the year ended April 30, 2007, this waiver amounted to $1,006,293 and is reflected as a reduction of total expenses in the Statement of Operations. Certain Class A, Class C and Class 529C shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within 12 months of purchase. Class B and Class 529B 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 year ended April 30, 2007, were as follows: AMOUNT Class A $8,545 Class B $153,240 Class C $10,622 Class 529B $0 Class 529C $0 The fund has entered into and may from time to time enter into contracts with program managers and other parties which administer the tuition programs through which an investment in the fund's 529 share classes is made. The fund has entered into an agreement with MFD pursuant to which MFD receives an annual fee of up to 0.35% of the average daily net assets attributable to each 529 share class. The fee is based on average daily net assets and is currently established at 0.25% annually of average daily net assets of the fund's 529 share classes. The fee may only be increased with the approval of the Board of Trustees who oversees the fund. The services provided by MFD, or a third party with which MFD contracts, include recordkeeping and tax reporting and account services, as well as services designed to maintain the program's compliance with the Internal Revenue Code and other regulatory requirements. Program manager fees for the year ended April 30, 2007, were as follows: AMOUNT Class 529A $1,765 Class 529B 454 Class 529C 791 ------------------------------------------- Total Program Manager Fees $3,010 SHAREHOLDER SERVICING AGENT - MFS Service Center, Inc. (MFSC), a wholly-owned subsidiary of MFS, receives a fee from the fund for its services as shareholder servicing agent calculated as a percentage of the average daily net assets of the fund as determined periodically under the supervision of the fund's Board of Trustees. For the year ended April 30, 2007, the fee was $1,563,531, which equated to 0.0779% annually of the fund's average daily net assets. MFSC also receives payment from the fund for out-of-pocket expenses, sub-accounting and other shareholder servicing costs which may be paid to affiliated and unaffiliated service providers. For the year ended April 30, 2007, these out-of-pocket expenses, sub-accounting and other shareholder servicing costs amounted to $993,238. The fund may also pay shareholder servicing related costs directly to non-related parties. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to the fund. Under an administrative services agreement, the fund partially reimburses MFS the costs incurred to provide these services. The fund is charged a fixed amount plus a fee based on calendar year average net assets. The fund's annual fixed amount is $17,500. The administrative services fee incurred for the year ended April 30, 2007 was equivalent to an annual effective rate of 0.0177% of the fund's average daily net assets. In addition to the administrative services provided by MFS to the fund as described above, MFS is responsible for providing certain retirement plan administration and services with respect to certain shares.

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. 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 year ended April 30, 2007, the fee paid to Tarantino LLC was $12,849. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $10,076, which is shown as a reduction of total expenses in the Statement of Operations.

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 Conservative Allocation Fund, MFS Moderate Allocation Fund and MFS Growth Allocation Fund were the owners of record of approximately 2%, 10% and 12%, respectively, of the value of outstanding voting shares. In addition, the MFS Lifetime Retirement Income Fund, MFS Lifetime 2010 Fund, 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 funds managed by MFS 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 funds managed by MFS 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 0.30% for the committed line of credit and 0.35% for the uncommitted line of credit. 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 year ended April 30, 2007, the fund's commitment fee and interest expense were $8,908 and $1,944, respectively, and are included in miscellaneous expense on the Statement of Operations. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To The Trustees of MFS Series Trust IX and the Shareholders of MFS Research Bond Fund: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of MFS Research Bond Fund (one of the portfolios comprising MFS Series Trust IX (the "Trust")) as of April 30, 2007, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Trust'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 the standards of the Public Company Accounting Oversight Board (United States). 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. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of April 30, 2007, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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 Research Bond Fund as of April 30, 2007, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

(n) In 2004 and 2005, Mr. Butler provided consulting services to the independent compliance consultant retained by MFS pursuant to its settlement with the SEC concerning market timing and related matters. The terms of that settlement required that compensation and expenses related to the independent compliance consultant be borne exclusively by MFS and, therefore, MFS paid Mr. Butler for the services he rendered to the independent compliance consultant. In 2004 and 2005, MFS paid Mr. Butler a total of $351,119.29. The Trust held a shareholders' meeting in 2005 to elect Trustees, and will hold a shareholders' meeting at least once every five years thereafter, to elect Trustees. Each Trustee (except Mr. Butler and Mr. Uek) has been elected by shareholders and each Trustee and officer holds office until his or her successor is chosen and qualified or until his or her earlier death, resignation, retirement or removal. Messrs. Butler, Gutow, Sherratt and Uek and Ms. Thomsen are members of the Trust's Audit Committee. Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or a subsidiary is the investment adviser or distributor, and, in the case of the officers, with certain affiliates of MFS.

Manning] Dear Shareholders: The past year has been a great example of why investors should keep their eyes on the long term. In 2006 the Dow Jones Industrial Average returned 19%. As of mid-May 2007, it had returned another 8% and continued to reach new highs. But the Dow's upward rise has not been without hiccups. After hitting new records in February, the Dow lost 5.8% between February 20 and March 5, as stocks were sold off around the globe. As we have said before, markets are volatile, and investors should make sure they have an investment plan that can carry them through the peaks and troughs. If you are focused on a long-term investment strategy, the short-term ups and downs of the markets should not necessarily dictate portfolio action on your part. Both the bond and stock markets are cyclical. In our view, investors who remain committed to a long-term plan are more likely to achieve their financial goals. We believe you should not let the headlines guide you in your investment decisions and should be cautious about overreacting to short-term volatility. In any market environment, we believe individual investors are best served by following a three-pronged investment strategy of allocating their holdings across the major asset classes, diversifying within each class, and regularly rebalancing their portfolios to maintain their desired allocations. Of course, these strategies cannot guarantee a profit or protect against a loss. Investing and planning for the long term require 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 Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) June 15, 2007 The opinions expressed in this letter are subject to change, may not be relied upon for investment advice, and no forecasts can be guaranteed.

(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 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 the "AAA"-rating category. Percentages are based on the total market value of investments as of 04/30/07. Percentages are based on net assets as of 04/30/07, unless otherwise noted. The portfolio is actively managed and current holdings may be different. MANAGEMENT REVIEW SUMMARY OF RESULTS For the twelve months ended April 30, 2007, Class B shares of the MFS Research Bond Fund J provided a total return of 6.03%, at net asset value. This compares with a return of 7.35% for the fund's benchmark, the Lehman Brothers U.S. Aggregate Bond Index (the Lehman Index). DETRACTORS FROM PERFORMANCE The fund's overweighted position in U.S. Treasuries detracted from results relative to the Lehman Index. The fund's holdings of asset-backed securities were also a drag on performance. Having an underweighted position in the strong-performing mortgage-backed securities sector hurt relative results over the reporting period. This positioning was due in large part to the negative convexity(c) of the asset class. CONTRIBUTORS TO PERFORMANCE The fund's positioning in corporate bonds added to relative results. Other areas that contributed to performance included our holdings of high yield bonds and emerging market debt which the index does not own. The fund also benefited from holding higher-yielding securities than the benchmark. Respectfully Robert Persons Michael Roberge Jeffrey Wakelin Portfolio Managers Portfolio Manager Portfolio Manager (c) Convexity is a measure of the curvature of the price-yield curve. The combination of duration and convexity provides a better approximation of a bond's sensitivity to changes in interest rates. Duration provides a first order approximation of how much a bond price will drop with rising interest rates or rise with falling interest rates. Positive convexity implies an additional positive impact for all interest rate movements; negative convexity implies an additional negative impact. The views expressed in this report are those of the portfolio managers only through the end of the period of the report as stated on the cover and do not necessarily reflect the views of MFS or any other person in the MFS organization.

PERFORMANCE SUMMARY THROUGH 4/30/07 The following chart illustrates the fund's historical performance in comparison to its benchmark. Performance results include the deduction of the maximum applicable sales charge and reflect the percentage change in net asset value, including reinvestment of dividends and capital gains distributions. Benchmark comparisons are unmanaged; do not reflect sales charges, commissions or expenses; and cannot be invested in directly. (See Notes to Performance Summary).

INDEX DEFINITION Lehman Brothers U.S. Aggregate Bond Index - measures the U.S. investment grade, fixed rate bond market, with index components for government and corporate securities, mortgage pass-through securities, and asset-backed securities. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Prior to December 22, 2003, the Research Bond Fund J (the "fund") was a "fund of funds" and invested all of its assets in Class I shares of the MFS Research Bond Fund, an open-end investment company that has the same investment objective as the fund. Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance results would be less favorable. Please see the prospectus and financial statements for complete details. From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower. EXPENSE TABLE FUND EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, NOVEMBER 1, 2006 THROUGH APRIL 30, 2007. 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 November 1, 2006 through April 30, 2007. ACTUAL EXPENSES The first line 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 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 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. - -------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period (p) Expense Account Value Account Value 11/01/06- Ratio 11/01/06 4/30/07 4/30/07 - -------------------------------------------------------------------------------- Actual 1.63% $1,000.00 $1,021.40 $8.17 - -------------------------------------------------------------------------------- Hypothetical (h) 1.63% $1,000.00 $1,016.71 $8.15 - -------------------------------------------------------------------------------- (h) 5% class return per year before expenses. (p) Expenses paid is equal to the fund's 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.

(k) As of April 30, 2007, the fund held securities fair valued in accordance with the policies adopted by the Board of Trustees, aggregating $161,638,170 and 96.17% of market value. An independent pricing service provided an evaluated bid for 95.73% of the market value. (n) Securities exempt from registration under Rule 144A of the Securities Act of 1933. These securities may be sold in the ordinary course of business in transactions exempt from registration, normally to qualified institutional buyers. At period end, the aggregate value of these securities was $11,680,850, representing 6.9% of net assets. (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 price may be difficult.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (1) BUSINESS AND ORGANIZATION MFS Research Bond Fund J (the fund) is a 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 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 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 - 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. Short-term instruments with a maturity at issuance of 60 days or less may be valued at amortized cost, which approximates market value. Futures contracts are generally valued at last posted settlement price as reported by an independent pricing service on the market on which they are primarily traded. Futures contracts for which there were no trades that day for a particular position are generally valued at the closing bid quotation as reported by an independent pricing service on the market on which such futures contracts are primarily traded. Swaps are generally valued at an evaluated bid as reported by an independent pricing service. 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. Values 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. 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 and certain types of derivatives. These investments are generally valued at fair value based on information from independent pricing services. 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 securities may often be valued at fair value. 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 September 2006, FASB Statement No. 157, Fair Value Measurements (the "Statement") was issued, and is effective for fiscal years beginning after November 15, 2007 and for all interim periods within those fiscal years. This Statement provides a single definition of fair value, a hierarchy for measuring fair value and expanded disclosures about fair value measurements. Management is evaluating the application of the Statement to the fund, and believes the impact will be limited to expanded disclosures resulting from the adoption of this Statement in the fund's financial statements. In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159 (FAS 159) "The Fair Value Option for Financial Assets and Financial Liabilities - including an amendment of FASB Statement No. 115." FAS 159 permits entities to elect to measure certain financial assets and liabilities at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be reported in earnings at each subsequent reporting date. FAS 159 is effective for fiscal years beginning after November 15, 2007. Management is evaluating the application of the Statement to the fund and its impact on the fund's financial statements, if any, has not been determined. 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 and other funds managed by Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. INFLATION-ADJUSTED DEBT SECURITIES - The fund invests in inflation-adjusted debt securities issued by the U.S. Treasury. The fund may also invest in inflation-adjusted debt securities issued by U.S. Government agencies and instrumentalities other than the U.S. Treasury and by other entities such as U.S. and foreign corporations and foreign governments. The principal value of these debt securities is adjusted by references to changes in the Consumer Price Index or another general price or wage index. These debt securities typically pay a fixed rate of interest, but this fixed rate is applied to the inflation-adjusted principal amount. The principal paid at maturity of the debt security is typically equal to the inflation-adjusted principal amount, or the security's original par value, whichever is greater. Other types of inflation-adjusted securities may use other methods to adjust for other measures of inflation. 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 futures contracts and swap agreements. FUTURES CONTRACTS - The fund may enter into futures contracts for the delayed delivery of securities or 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 with the broker 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 contract, and are recorded for financial statement purposes as unrealized gains or losses by the fund. Upon entering into such contracts, the fund bears the risk of interest or exchange rates or securities prices moving unexpectedly, in which case, the fund may not achieve the anticipated benefits of the futures contracts and may realize a loss. 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, including accruals of periodic amounts of interest to be paid or received, is recorded as unrealized appreciation or depreciation in the Statement of Operations. A liquidation payment received or made upon early termination is recorded as a realized gain or loss in the Statement of Operations. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with the fund's custodian in connection with these agreements. Risk of loss may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include the possible lack of a liquid market, failure of the counterparty to perform under the terms of the agreements, and unfavorable market movement of the underlying instrument. All swap agreements entered into by the fund with the same counterparty are generally governed by a single master agreement, which provides for the netting of all amounts owed by the parties under the agreement upon the occurrence of an event of default, thereby reducing the credit risk to which such party is exposed. The fund holds a credit default swap in which one party makes a stream of payments based on a fixed percentage applied to the notional amount 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. The fund may enter into credit default swaps to limit or to reduce its risk exposure to defaults of corporate and sovereign issuers or to create direct or synthetic short or long exposure to corporate debt securities or certain sovereign debt securities to which it is not otherwise exposed. 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. INDEMNIFICATIONS - Under the fund's organizational documents, its officers and trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the fund. Additionally, in the normal course of business, the fund enters into agreements with service providers that may contain indemnification clauses. The fund's maximum exposure under these agreements is unknown as this would involve future claims that may be made against the fund that have not yet occurred. 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, facility fees, consent fees, and prepayment fees. These fees are recorded on an accrual basis as income in the accompanying financial statements. The fund may receive proceeds from litigation settlements. Any proceeds received from litigation involving portfolio holdings are reflected in the Statement of Operations in realized gain/loss if the security has been disposed of by the fund or in unrealized gain/loss if the security is still held by the fund. Any other proceeds from litigation not related to portfolio holdings are reflected as other income in the Statement of Operations. 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 year ended April 30, 2007, 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 U.S. 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 and derivative transactions. The tax character of distributions declared to shareholders is as follows: 4/30/07 4/30/06 Ordinary income $7,665,374 9,362,310 The federal tax cost and the tax basis components of distributable earnings were as follows: AS OF 4/30/07 Cost of investments $169,219,359 --------------------------------------------------------------- Gross appreciation 1,063,894 Gross depreciation (2,210,627) --------------------------------------------------------------- Net unrealized appreciation (depreciation) $(1,146,733) Undistributed ordinary income 625,812 Capital loss carryforwards (8,846,567) Post-October capital loss deferral (253,611) Other temporary differences (584,962) As of April 30, 2007, the fund had capital loss carryforwards available to offset future realized gains. Such losses expire as follows: 4/30/13 $(1,678,843) 4/30/14 (1,444,482) 4/30/15 (5,723,242) ------------------------------------- $(8,846,567) 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. On December 22, 2006, the SEC delayed the implementation of the Interpretation for regulated investment companies for an additional six months. 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 evaluated the application of the Interpretation to the fund, and has determined that there is no impact resulting from the adoption of this Interpretation on the fund's financial statements. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund has an investment advisory agreement with MFS to provide overall investment management and related administrative services and facilities to the fund. The management fee is computed daily and paid monthly at an annual rate of 0.50% of the fund's average daily net assets. The investment adviser has agreed in writing to reduce its management fee to 0.35% of average daily net assets. This written agreement may be rescinded only upon consent of the fund's Board of Trustees. This management fee reduction amounted to $274,805, which is shown as a reduction of total expenses in the Statement of Operations. The management fee incurred for the year ended April 30, 2007 was equivalent to an annual effective rate of 0.35% of the fund's average daily net assets. The investment adviser has agreed in writing to pay a portion of the fund's operating expenses, exclusive of management, distribution and service, and certain other fees and expenses, such that operating expenses do not exceed 0.25% annually of the fund's average daily net assets. This written agreement will continue through August 31, 2007 unless changed or rescinded by the fund's Board of Trustees. For the year ended April 30, 2007, the fund's actual operating expenses did not exceed the limit and therefore, the investment adviser did not pay any portion of the fund's expenses. DISTRIBUTOR - 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 MFS Fund Distributors, Inc. (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. Distribution Fee Plan Table: TOTAL ANNUAL DISTRIBUTION DISTRIBUTION SERVICE DISTRIBUTION EFFECTIVE AND SERVICE FEE RATE FEE RATE PLAN(d) RATE(e) FEE Class B 0.75% 0.25% 1.00% 1.00% $1,832,031 (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 year ended April 30, 2007 based on each class' average daily net assets. Class B shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within five years of purchase. All contingent deferred sales charges are paid to MFD and during the year ended April 30, 2007, were as follows: AMOUNT Class B $4,845,987 SHAREHOLDER SERVICING AGENT - MFS Service Center, Inc. (MFSC), a wholly-owned subsidiary of MFS, receives a fee from the fund for its services as shareholder servicing agent calculated as a percentage of the average daily net assets of the fund as determined periodically under the supervision of the fund's Board of Trustees. For the year ended April 30, 2007, the fee was $147,666, which equated to 0.0806% annually of the fund's average daily net assets. MFSC also receives payment from the fund for out-of-pocket expenses, sub-accounting and other shareholder servicing costs which may be paid to affiliated and unaffiliated service providers. For the year ended April 30, 2007, these out-of-pocket expenses, sub-accounting and other shareholder servicing costs amounted to $56. The fund may also pay shareholder servicing related costs directly to non-related parties. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to the fund. Under an administrative services agreement, the fund partially reimburses MFS the costs incurred to provide these services. The fund is charged a fixed amount plus a fee based on calendar year average net assets. The fund's annual fixed amount is $17,500. The administrative services fee incurred for the year ended April 30, 2007 was equivalent to an annual effective rate of 0.0226% 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. 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 year ended April 30, 2007, the fee paid to Tarantino LLC was $1,168. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $936, 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.

Interest is charged to each fund, based on its borrowings, generally at a rate equal to the Federal Reserve funds rate plus 0.30% for the committed line of credit and 0.35% for the uncommitted line of credit.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To The Trustees of MFS Series Trust IX and the Shareholders of MFS Research Bond Fund J: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of MFS Research Bond Fund J (one of the portfolios comprising MFS Series Trust IX (the "Trust")) as of April 30, 2007, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the four years in the period then ended and for the period October 17, 2002 (commencement of operations) to April 30, 2003. These financial statements and financial highlights are the responsibility of the Trust'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 the standards of the Public Company Accounting Oversight Board (United States). 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. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of April 30, 2007, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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 Research Bond Fund J as of April 30, 2007, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the four years in the period then ended and for the period October 17, 2002 (commencement of operations) to April 30, 2003, in conformity with accounting principles generally accepted in the United States of America.

Each of the Trust's Trustees and officers holds comparable positions with certain other funds of which MFS or a subsidiary is the investment adviser or distributor, and, in the case of the officers, with certain affiliates of MFS.

CODE OF ETHICS. The Registrant has adopted a Code of Ethics pursuant to Section 406 of the Sarbanes-Oxley Act and as defined in Form N-CSR that applies to the Registrant's principal executive officer and principal financial and accounting officer. The Registrant has not amended any provision in its Code of Ethics (the "Code") that relates to an element of the Code's definitions enumerated in paragraph (b) of Item 2 of this Form N-CSR.

The Securities and Exchange Commission has stated that the designation of a person as an audit committee financial expert pursuant to this Item 3 on the Form N-CSR does not impose on such a person any duties, obligations or liability that are greater than the duties, obligations or liability imposed on such person as a member of the Audit Committee and the Board of Trustees in the absence of such designation or identification.

(1) The fees included under "Audit-Related Fees" are fees related to assurance and related services that are reasonably related to the performance of the audit or review of financial statements, but not reported under "Audit Fees," including accounting consultations, agreed-upon procedure reports, attestation reports, comfort letters and internal control reviews. (2) The fees included under "Tax Fees" are fees associated with tax compliance, tax advice and tax planning, including services relating to the filing or amendment of federal, state or local income tax returns, regulated investment company qualification reviews and tax distribution and analysis. (3) The fees included under "All Other Fees" are fees for products and services provided by Deloitte other than those reported under "Audit Fees," "Audit-Related Fees" and "Tax Fees," including fees for services related to sales tax refunds, consultation on internal cost allocations, review of internal controls and review of Rule 38a-1 compliance program. ITEM 4(e)(1): Set forth below are the policies and procedures established by the Audit Committee of the Board of Trustees relating to the pre-approval of audit and non-audit related services: To the extent required by applicable law, pre-approval by the Audit Committee of the Board is needed for all audit and permissible non-audit services rendered to the Funds and all permissible non-audit services rendered to MFS or MFS Related Entities if the services relate directly to the operations and financial reporting of the Registrant. Pre-approval is currently on an engagement-by-engagement basis. In the event pre-approval of such services is necessary between regular meetings of the Audit Committee and it is not practical to wait to seek pre-approval at the next regular meeting of the Audit Committee, pre-approval of such services may be referred to the Chair of the Audit Committee for approval; provided that the Chair may not pre-approve any individual engagement for such services exceeding $50,000 or multiple engagements for such services in the aggregate exceeding $100,000 in each period between regular meetings of the Audit Committee. Any engagement pre-approved by the Chair between regular meetings of the Audit Committee shall be presented for ratification by the entire Audit Committee at its next regularly scheduled meeting ITEM 4(e)(2): None, or 0%, of the services relating to the Audit-Related Fees, Tax Fees and All Other Fees paid by the Fund and MFS and MFS Related Entities relating directly to the operations and financial reporting of the Registrant disclosed above were approved by the audit committee pursuant to paragraphs (c)(7)(i)(C) of Rule 2-01 of Regulation S-X (which permits audit committee approval after the start of the engagement with respect to services other than audit, review or attest services, if certain conditions are satisfied). ITEM 4(f): Not applicable. ITEM 4(h): The Registrant's Audit Committee has considered whether the provision by a Registrant's independent registered public accounting firm of non-audit services to MFS and MFS Related Entities that were not pre-approved by the Committee (because such services did not relate directly to the operations and financial reporting of the Registrant) was compatible with maintaining the independence of the independent registered public accounting firm as the Registrant's principal auditors.

SCHEDULE OF INVESTMENTS A schedule of investments of the Registrant is included as part of the report to shareholders of such series under Item 1 of this Form N-CSR. ITEM 7.

There were no material changes to the procedures by which shareholders may send recommendations to the Board for nominees to the Registrant's Board since the Registrant last provided disclosure as to such procedures in response to the requirements of Item 407(c)(2)(iv) of Regulation S-K (as required by Item 22(b)(15) of Schedule 14A), or this Item. ITEM 11. CONTROLS AND PROCEDURES. (a) Based upon their evaluation of the effectiveness of the registrant's disclosure controls and procedures (as defined in Rule 30a-3(c) under the Investment Company Act of 1940 (the "Act")) as conducted within 90 days of the filing date of this report on Form N-CSR, the registrant's principal financial officer and principal executive officer have concluded that those disclosure controls and procedures provide reasonable assurance that the material information required to be disclosed by the registrant on this report is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms.
