Managed Distribution Policy Disclosure

The MFS Intermediate Income Trusts (the fund) Board of Trustees has adopted a managed distribution policy. The fund seeks to pay monthly distributions based on an annual rate of 8.5% of the funds average monthly net asset value. The funds total return in relation to changes in net asset value is presented in the Financial Highlights. You should not draw any conclusions about the funds investment performance from the amount of the current distribution or from the terms of the funds managed distribution policy. The Board may amend or terminate the managed distribution policy at any time without prior notice to fund shareholders; however, at this time, there are no reasonably foreseeable circumstances that might cause the termination of the managed distribution policy.

With each distribution, the fund will issue a notice to shareholders and an accompanying press release which will provide detailed information regarding the amount and composition of the distribution and other related information. In accordance with the amounts and sources of distributions reported in the notice to shareholders the sources of distributions are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon the funds investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The fund will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.

Under a managed distribution policy the fund may at times distribute more than its net investment income and net realized capital gains; therefore, a portion of your distribution may result in a return of capital. A return of capital may occur, for example, when some or all of the money that you invested in the fund is paid back to you. A return of capital does not necessarily reflect the funds investment performance and should not be confused with yield or income.

LETTER FROM THE CHAIRMAN AND CEO

Dear Shareholders:

World financial markets remain a venue of uncertainty. The focus has shifted most recently to the eurozone, where elections in the 17-country region reflected a level of voter unwillingness to accept the austerity measures enacted in the midst of an economic slowdown. Volatility is likely to continue as investors watch how this voter backlash plays out in Europe and in other countries attempting to

resolve budget issues.

The U.S. economy is experiencing a period of growth. However, markets have been jittery in reaction to events in Europe and ahead of the U.S. presidential election. As in Europe, voters in the United States are watching the economy closely and waiting to see if Congress agrees to cut the budget and extend the Bush tax cuts. Failure to do so could ultimately send the U.S. economy back into recession.

Amid this global uncertainty, managing risk becomes a top priority for investors and their advisors. At MFS®, our global research platform is designed to ensure the smooth

functioning of our investment process in all business climates. Risk management is always foremost in our minds. Our research platform enables our analysts to uncover attractive global opportunities across asset classes. Additionally, we have a team of quantitative analysts that measures and assesses the risk profiles of our portfolios and securities on an ongoing basis. The chief investment risk officer, who oversees the team, reports directly to the firms president and chief investment officer so that the risk associated with each portfolio can be assessed objectively and independently of the portfolio management team.

We, like our investors, are mindful of the many economic challenges faced at the local, national, and international levels. It is in times such as these that we want to emphasize the merits of maintaining a long-term view, adhering to basic investing principles such as asset allocation and diversification, and working closely with investment advisors to research and identify appropriate investment opportunities.

Respectfully,

Robert J. Manning

Chairman and Chief Executive Officer

Portfolio Composition continued

(a) For all securities other than those specifically described below, ratings are assigned to underlying securities utilizing ratings from Moodys, Fitch, and Standard & Poors rating agencies and applying the following hierarchy: If all three agencies provide a rating, the middle rating (after dropping the highest and lowest ratings) is assigned; if two of the three agencies rate a security, the lower of the two is assigned. Ratings are shown in the S&P and Fitch scale (e.g., AAA). All ratings are subject to change. U.S. Government includes securities issued by the U.S. Department of the Treasury. Federal Agencies includes rated and unrated U.S. Agency fixed-income securities, U.S. Agency mortgage-backed securities, and collateralized mortgage obligations of U.S. Agency mortgage-backed securities. Not Rated includes fixed income securities, including fixed income futures, which have not been rated by any rating agency. Non-Fixed Income includes equity securities (including convertible bonds and equity derivatives) and commodities. Cash & Other includes cash, other assets less liabilities, offsets to derivative positions, and short-term securities. The fund may not hold all of these instruments. The fund is not rated by these agencies.

(d) Duration is a measure of how much a bonds 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 due to the interest rate move.

(i) For purposes of this presentation, the components include the market value of securities, and reflect the impact of the equivalent exposure of derivative positions, if any. These amounts may be negative from time to time. The bond component will include any accrued interest amounts. Equivalent exposure is a calculated amount that translates the derivative position into a reasonable approximation of the amount of the underlying asset that the portfolio would have to hold at a given point in time to have the same price sensitivity that results from the portfolios ownership of the derivative contract. When dealing with derivatives, equivalent exposure is a more representative measure of the potential impact of a position on portfolio performance than market value. Where the fund holds convertible bonds, these are treated as part of the equity portion of the portfolio.

(m) In determining an instruments effective maturity for purposes of calculating the funds dollar-weighted average effective maturity, MFS uses the instruments stated maturity or, if applicable, an earlier date on which MFS believes it is probable that a maturity-shortening device (such as a put, pre-refunding or prepayment) will cause the instrument to be repaid. Such an earlier date can be substantially shorter than the instruments stated maturity.

(o) Less than 0.1%.

(x) Represents the portfolios exposure to issuer countries as a percentage of a portfolios net assets.

From time to time Cash & Other Net Assets may be negative due to timing of cash receipts and/or equivalent exposure from any derivative holdings.

Percentages are based on net assets as of 4/30/12.

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

PORTFOLIO MANAGERS PROFILES

James Calmas		Investment Officer of MFS; employed in the investment management area of MFS since 1988. Portfolio Manager of the Fund since March 2002.

OTHER NOTES

The funds shares may trade at a discount or premium to net asset value. Shareholders do not have the right to cause the fund to repurchase their shares at net asset value. When fund shares trade at a premium, buyers pay more than the net asset value underlying fund shares, and shares purchased at a premium would receive less than the amount paid for them in the event of the funds liquidation. As a result, the total return that is calculated based on the net asset value and New York Stock Exchange price can be different.

The funds monthly distributions may include a return of capital to shareholders to the extent that the funds net investment income and net capital gains are insufficient to meet the funds target annual distribution rate. Distributions that are treated for federal income tax purposes as a return of capital will reduce each shareholders basis in his or her shares and, to the extent the return of capital exceeds such basis, will be treated as gain to the shareholder from a sale of shares. It may also result in a recharacterization of what economically represents a return of capital to ordinary income in those situations where a fund has long term capital gain and a capital loss carryforward. Returns of shareholder capital have the effect of reducing the funds assets and increasing the funds expense ratio.

The funds target annual distribution rate is calculated based on an annual rate of 8.5% of the funds average monthly net asset value, not a fixed share price, and the funds dividend amount will fluctuate with changes in the funds average monthly net assets.

In accordance with Section 23(c) of the Investment Company Act of 1940, the fund hereby gives notice that it may from time to time repurchase shares of the fund in the open market at the option of the Board of Trustees and on such terms as the Trustees shall determine.

(a) Net unamortized premiums received by the fund amounted to $4,390.

The credit ratings presented here are an indicator of the current payment/performance risk of the related swap, the reference obligation for which may be either a single security or, in the case of a credit default index, a basket of securities issued by corporate or sovereign issuers. Ratings are assigned to each reference security, including each individual security within a reference basket of securities, utilizing ratings from Moodys, Fitch, and Standard & Poors rating agencies and applying the following hierarchy: If all three agencies provide a rating, the middle rating (after dropping the highest and lowest ratings) is assigned; if two of the three agencies rate a security, the lower of the two is assigned. Ratings are shown in the S&P and Fitch scale (e.g., AAA). The ratings for a credit default index are calculated by MFS as a weighted average of the external credit ratings of the individual securities that compose the indexs reference basket of securities.

At April 30, 2012, the fund had sufficient cash and/or securities to cover any commitments under these derivative contracts.

(unaudited)

(1) Business and Organization

MFS Intermediate Income Trust (the fund) is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as a closed-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. In the preparation of these financial statements, management has evaluated subsequent events occurring after the date of the funds Statement of Assets and Liabilities through the date that the financial statements were issued. The fund invests 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 countrys 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.

In December 2011, the Financial Accounting Standards Board issued Accounting Standards Update 2011-11, Balance Sheet (Topic 210) Disclosures about Offsetting Assets and Liabilities (ASU 2011-11). Effective for annual reporting periods beginning on or after January 1, 2013 and interim periods within those annual periods, ASU 2011-11 is intended to enhance disclosure requirements on the offsetting of financial assets and liabilities. Although still evaluating the potential impacts of ASU 2011-11 to the fund, management expects that the impact of the funds adoption will be limited to additional financial statement disclosures.

Investment Valuations Debt instruments and floating rate loans (other than short-term instruments), including restricted debt instruments, are generally valued at an evaluated or composite bid as provided by a third-party pricing service. Short-term instruments with a maturity at issuance of 60 days or less generally are valued at amortized cost, which approximates market value. Futures contracts are generally valued at last posted settlement price as provided by a third-party pricing service on the market on which they are primarily traded. Futures contracts for which there were no trades that day for

Notes to Financial Statements (unaudited) continued

a particular position are generally valued at the closing bid quotation as provided by a third-party pricing service on the market on which such futures contracts are primarily traded. Forward foreign currency exchange contracts are generally valued at the mean of bid and asked prices for the time period interpolated from rates provided by a third-party pricing service for proximate time periods. Swaps are generally valued at valuations provided by a third-party pricing service. Open-end investment companies are generally valued at net asset value per share. Securities and other assets generally valued on the basis of information from a third-party pricing service may also be valued at a broker/dealer bid quotation. Values obtained from third-party pricing services can utilize both transaction data and market information such as 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 provided by a third-party pricing service.

The Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of the funds 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 funds valuation policies and procedures, market quotations are not considered to be readily available for most types of debt instruments and floating rate loans and many types of derivatives. These investments are generally valued at fair value based on information from third-party pricing services. In addition, investments may be valued at fair value if the adviser determines that an investments 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 funds 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. The adviser generally relies on third-party 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 funds net asset value can differ depending on the source and method used to determine value. When fair valuation is used, the value of an investment used to determine the funds net asset value may differ from quoted or published prices for the same

investment. There can be no assurance that the fund could obtain the fair value assigned to an investment if it were to sell the investment at the same time at which the fund determines its net asset value per share.

Various inputs are used in determining the value of the funds assets or liabilities. These inputs are categorized into three broad levels. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investments level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The funds assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment. Level 1 includes unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 includes other significant observable market-based inputs (including quoted prices for similar securities, interest rates, prepayment speed, and credit risk). Level 3 includes unobservable inputs, which may include the advisers own assumptions in determining the fair value of investments. Other financial instruments are derivative instruments not reflected in total investments, such as futures, forward foreign currency exchange contracts, and swap contracts. The following is a summary of the levels used as of April 30, 2012 in valuing the funds assets or liabilities:

Investments at Value — U.S. Treasury Bonds & U.S. Government Agency & Equivalents	$	$15,546,157		$	$15,546,157
Non-U.S. Sovereign Debt		199,115,081			199,115,081

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 or on the reporting date for foreign denominated receivables and payables. 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 receivables, payables, 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.

Derivatives The fund uses derivatives for different purposes, primarily to increase or decrease exposure to a particular market or segment of the market, or security, to increase or decrease interest rate or currency exposure, or as alternatives to direct investments. Derivatives are used 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 increase market exposure, or for hedging purposes, gains and losses from derivative instruments may be substantially greater than the derivatives original cost.

The derivative instruments used by the fund were futures contracts, forward foreign currency exchange contracts, and swap agreements. The funds period end derivatives, as presented in the Portfolio of Investments and the associated Derivative Contract Tables, generally are indicative of the volume of its derivative activity during the period.

The following table presents, by major type of derivative contract, the fair value, on a gross basis, of the asset and liability components of derivatives held by the fund at April 30, 2012 as reported in the Statement of Assets and Liabilities:

Risk	Derivative Contracts	Fair Value (a) — Asset Derivatives	Liability Derivatives
Interest Rate	Interest Rate Futures	$163,667	$
Foreign Exchange	Forward Foreign Currency Exchange		(1,414,536	)

The following table presents, by major type of derivative contract, the change in unrealized appreciation (depreciation) on derivatives held by the fund for the six months ended April 30, 2012 as reported in the Statement of Operations:

Risk — Interest Rate	$159,321	$		$

Derivative counterparty credit risk is managed through formal evaluation of the creditworthiness of all potential counterparties. On certain over-the-counter derivatives, the fund attempts to reduce its exposure to counterparty credit risk whenever possible by entering into an International Swaps and Derivatives Association (ISDA) Master Agreement on a bilateral basis with each of the counterparties with whom it undertakes a significant volume of transactions. The ISDA Master Agreement gives each party to the agreement the right to terminate all transactions traded under such agreement if there is a certain deterioration in the credit quality of the other party. The ISDA Master Agreement gives the fund the right, upon an event of default by the applicable counterparty or a termination of the agreement, to close out all transactions traded under such agreement and to net amounts owed under each transaction to one net amount payable by one party to the other. This right to close out and net payments across all transactions traded under the ISDA Master Agreement could result in a reduction of the funds credit risk to such counterparty equal to any amounts payable by the fund under the applicable transactions, if any. However, absent an event of default by the counterparty or a termination of the agreement, the ISDA Master Agreement does not result in an offset of reported amounts of assets and liabilities in the Statement of Assets and Liabilities across transactions between the fund and the applicable counterparty.

Collateral requirements differ by type of derivative. Collateral or margin requirements are set by the broker or exchange clearing house for exchange traded derivatives (i.e., futures and exchange-traded options) while collateral terms are contract specific for over-the-counter traded derivatives (i.e., forward foreign currency exchange contracts, swaps and over-the-counter options). For derivatives traded under an ISDA Master Agreement, the collateral requirements are netted across all transactions traded under such agreement and one amount is posted from one party to the other to collateralize such obligations. Cash collateral that has been pledged to cover obligations of the fund under derivative contracts, if any, will be reported separately on the Statement of Assets and Liabilities as restricted cash. Securities collateral pledged for the same purpose, if any, is noted in the Portfolio of Investments.

Futures Contracts The fund entered into futures contracts which may be used to hedge against or obtain broad market, interest rate, duration, or currency exposure. A futures contract represents a commitment for the future purchase or sale of an asset at a specified price on a specified date.

Upon entering into a futures contract, the fund is required to deposit with the broker, either in cash or securities, an initial margin in an amount equal to a certain percentage of the notional amount of the contract. Subsequent payments (variation margin) 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 gain or loss by the fund until the contract is closed or expires at which point the gain or loss on futures is realized.

The fund bears the risk of interest rates, 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. While futures may present less counterparty risk to the fund since the contracts are exchange traded and the exchanges clearinghouse guarantees payments to the broker, there is still counterparty credit risk due to the insolvency of the broker. The funds maximum risk of loss due to counterparty credit risk is equal to the margin posted by the fund to the broker plus any gains or minus any losses on the outstanding futures contracts.

Forward Foreign Currency Exchange Contracts The fund entered into forward foreign currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. These contracts may be used to hedge the funds currency risk or for non-hedging purposes. For hedging purposes, the fund may enter into contracts to deliver or receive foreign currency that the fund will receive from or use in its normal investment activities. The fund may also use contracts to hedge against declines in the value of foreign currency denominated securities due to

Table of Contents

Notes to Financial Statements (unaudited) continued

unfavorable exchange rate movements. For non-hedging purposes, the fund may enter into contracts with the intent of changing the relative exposure of the funds portfolio of securities to different currencies to take advantage of anticipated exchange rate changes.

Forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any unrealized gains or losses are recorded as a receivable or payable for forward foreign currency exchange contracts until the contract settlement date. On contract settlement date, any gain or loss on the contract is recorded as realized gains or losses on foreign currency transactions.

Risks may arise upon entering into these contracts from unanticipated movements in the value of the contract and from the potential inability of counterparties to meet the terms of their contracts. Generally, the funds maximum risk due to counterparty credit risk is the unrealized gain on the contract due to the use of Continuous Linked Settlement, an industry accepted settlement system. This risk is mitigated in cases where there is an ISDA Master Agreement between the fund and the counterparty providing for netting as described above and for posting of collateral by the counterparty to the fund to cover the funds exposure to the counterparty under such ISDA Master Agreement.

Swap Agreements The fund entered into swap agreements. A swap is generally an exchange of cash payments, at specified intervals or upon the occurrence of specified events, between the fund and a counterparty. The net cash payments exchanged are recorded as a realized gain or loss on swap transactions in the Statement of Operations. The value of the swap, which is adjusted daily and includes any related interest accruals to be paid or received by the fund, is recorded on the Statement of Assets and Liabilities. The daily change in value, including any related interest accruals to be paid or received, is recorded as unrealized appreciation or depreciation on swap transactions in the Statement of Operations. Amounts paid or received at the inception of the swap are reflected as premiums paid or received on the Statement of Assets and Liabilities and are amortized using the effective interest method over the term of the agreement. A liquidation payment received or made upon early termination is recorded as a realized gain or loss on swap transactions in the Statement of Operations.

Risks related to swap agreements include the possible lack of a liquid market, unfavorable market and interest rate movements of the underlying instrument and the failure of the counterparty to perform under the terms of the agreements. To address counterparty risk, swap transactions are limited to only highly-rated counterparties. The risk is further mitigated by having an ISDA Master Agreement between the fund and the counterparty providing for

Table of Contents

Notes to Financial Statements (unaudited) continued

netting as described above and by the posting of collateral by the counterparty to the fund to cover the funds exposure to the counterparty under such ISDA Master Agreement.

The fund entered into credit default swaps in order to manage its exposure to the market or certain sectors of the market, to reduce its credit risk exposure to defaults of corporate and sovereign issuers or to create exposure to corporate or sovereign issuers to which it is not otherwise exposed. In a credit default swap, the protection buyer can make an upfront payment and will make a stream of payments based on a fixed percentage applied to the contract notional amount to the protection seller in exchange for the right to receive a specified return upon the occurrence of a defined credit event on the reference obligation (which may be either a single security or a basket of securities issued by corporate or sovereign issuers) and, with respect to the rare cases where physical settlement applies, the delivery by the buyer to the seller of a defined deliverable obligation. Although contract-specific, credit events generally consist of a combination of the following: bankruptcy, failure to pay, restructuring, obligation acceleration, obligation default, or repudiation/moratorium, each as defined in the 2003 ISDA Credit Derivatives Definitions as amended by the relevant contract. Restructuring is generally not applicable when the reference obligation is issued by a North American corporation and obligation acceleration, obligation default, or repudiation/moratorium are generally only applicable when the reference obligation is issued by a sovereign entity or an entity in an emerging country. Upon determination of the final price for the deliverable obligation (or upon delivery of the deliverable obligation in the case of physical settlement), the difference between the value of the deliverable obligation and the swaps notional amount is recorded as realized gain or loss on swap transactions in the Statement of Operations.

Credit default swaps are considered to have credit-risk-related contingent features since they trigger payment by the protection seller to the protection buyer upon the occurrence of a defined credit event. As discussed earlier in this note, any collateral requirements for these swaps are based generally on the market value of the swap netted against collateral requirements for other types of over-the-counter derivatives traded under each counterpartys ISDA Master Agreement. The maximum amount of future, undiscounted payments that the fund, as protection seller, could be required to make is equal to the swaps notional amount. The protection sellers payment obligation would be offset to the extent of the value of the contracts deliverable obligation. At April 30, 2012, the fund did not hold any credit default swaps at an unrealized loss where it is the protection seller.

The funds maximum risk of loss from counterparty risk, either as the protection seller or as the protection buyer, is the fair value of the contract. This risk is mitigated by having an ISDA Master Agreement between the fund

and the counterparty providing for netting as described above and by the posting of collateral by the counterparty to the fund to cover the funds exposure to the counterparty under such ISDA Master Agreement.

Indemnifications Under the funds 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 funds 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. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date.

The fund may receive proceeds from litigation settlements. 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 funds custody fee may be reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. This amount, for the six months ended April 30, 2012, 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. As a result, no provision for federal income tax is required. The funds federal tax returns, when filed, will remain subject to examination by the Internal Revenue Service for a three year period.

Distributions to shareholders are recorded on the ex-dividend date. The fund seeks to pay monthly distributions based on an annual rate of 8.5% of the funds average monthly net asset value. As a result, distributions may exceed actual earnings which may result in a tax return of capital or, to the extent the fund has long-term gains, distributions of current year long-term gains may be recharacterized as ordinary income. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from

Table of Contents

Notes to Financial Statements (unaudited) continued

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 from other sources, 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, straddle loss deferrals, and derivative transactions.

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

Ordinary income (including any short-term capital gains) (a)	$30,140,709
Tax return of capital (b)	35,082,544
Total distributions	$65,223,253
(a) Included
in the funds distributions from ordinary income is $2,521,277 in excess of investment company taxable income which, in accordance with applicable U.S. tax law, is taxable to shareholders as ordinary income distributions. (b) Distributions in excess of tax basis
earnings and profits are reported in the financial statements as a tax return of capital.

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

As of 4/30/12 — Cost of investments	$694,336,240
Gross appreciation	43,474,272
Gross depreciation	(5,892,836	)
Net unrealized appreciation (depreciation)	$37,581,436
As of 10/31/11
Capital loss carryforwards	(44,987,606	)
Other temporary differences	(18,839,786	)
Net unrealized appreciation (depreciation)	42,147,562

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

Notes to Financial Statements (unaudited) continued

Under the Regulated Investment Company Modernization Act of 2010 (the Act), net capital losses recognized after October 31, 2011 may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses. Previously, net capital losses were carried forward for eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses.

As of October 31, 2011 the fund had capital loss carryforwards available to offset future realized gains. Such losses expire as follows:

Pre-enactment losses: — 10/31/13	$(4,110,122	)
10/31/14	(19,143,361	)
10/31/15	(4,950,649	)
10/30/16	(16,783,474	)
Total	$(44,987,606	)

(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 0.32% of the funds average daily net assets and 5.65% of gross income. Gross income is calculated based on tax elections that generally include the accretion of discount and exclude the amortization of premium, which may differ from investment income reported in the Statement of Operations. MFS has agreed to reduce its management fee to the lesser of the contractual management fee as set forth above or 0.85% of the average daily net assets. This written agreement will continue until modified by the Board of Trustees, but such an agreement will continue at least until October 31, 2012. The management fee, from net assets and gross income, incurred for the six months ended April 30, 2012 was equivalent to an annual effective rate of 0.57% of the funds average daily net assets.

Transfer Agent The fund engages Computershare Trust Company, N.A. (Computershare) as the sole transfer agent for the fund. MFS Service Center, Inc. (MFSC) monitors and supervises the activities of Computershare for an agreed upon fee approved by the Board of Trustees. For the six months ended April 30, 2012, these fees paid to MFSC amounted to $28,981.

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 an annual fixed amount of $17,500 plus a fee based on average daily net assets.

Table of Contents

Notes to Financial Statements (unaudited) continued

The administrative services fee incurred for the six months ended April 30, 2012 was equivalent to an annual effective rate of 0.0166% of the funds 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 and MFSC.

Prior to December 31, 2001, the fund had an unfunded defined benefit plan (DB plan) for independent Trustees. As of December 31, 2001, the Board took action to terminate the DB plan with respect to then-current and any future independent Trustees, such that the DB plan covers only certain of those former independent Trustees who retired on or before December 31, 2001. Effective January 1, 2002, accrued benefits under the DB plan for then-current independent Trustees who continued were credited to an unfunded retirement deferral plan (the Retirement Deferral plan), which was established for and exists solely with respect to these credited amounts, and is not available for other deferrals by these or other independent Trustees. Although the Retirement Deferral plan is unfunded, amounts deferred under the plan are periodically adjusted for investment experience as if they had been invested in shares of the fund. The DB plan resulted in a pension expense of $1,457 and the Retirement Deferral plan resulted in an expense of $1,715. Both amounts are included in independent Trustees compensation for the six months ended April 30, 2012. The liability for deferred retirement benefits payable to certain independent Trustees under both plans amounted to $117,546 at April 30, 2012, and is included in Payable for independent Trustees compensation on the Statement of Assets and Liabilities.

Other This fund and certain other funds managed by MFS (the funds) have entered into services agreements (the Agreements) which provide for payment of fees by the funds to Tarantino LLC and Griffin Compliance LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) and Assistant ICCO, respectively, for the funds. The ICCO and Assistant ICCO are officers of the funds and the sole members of Tarantino LLC and Griffin Compliance LLC, respectively. The funds can terminate the Agreements with Tarantino LLC and Griffin Compliance LLC at any time under the terms of the Agreements. For the six months ended April 30, 2012, the aggregate fees paid by the fund to Tarantino LLC and Griffin Compliance LLC were $4,177 and are included in miscellaneous expense on the Statement of Operations. MFS has agreed to reimburse the fund for a portion of the payments made by the fund

Table of Contents

Notes to Financial Statements (unaudited) continued

in the amount of $1,276, 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 and Assistant ICCO.

The fund invests in the MFS Institutional Money Market Portfolio which is managed by MFS and seeks a high level of current income consistent with preservation of capital and liquidity. Income earned on this investment is included in dividends from underlying affiliated funds on the Statement of Operations. This money market fund does not pay a management fee to MFS.

(4) Portfolio Securities

Purchases and sales of investments, other than purchased option transactions and short-term obligations, were as follows:

U.S. Government securities	$122,004	$4,162,542
Investments (non-U.S. Government securities)	$110,553,611	$124,339,613

(5) Shares of Beneficial Interest

The funds Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. The Trustees have authorized the repurchase by the fund of up to 10% annually of its own shares of beneficial interest. During the six months ended April 30, 2012 and the year ended October 31, 2011, the fund did not repurchase any shares. Transactions in fund shares were as follows:

Shares	Amount	Shares	Amount
Shares issued to shareholders in reinvestment of distributions	291,580	$1,835,847	110,653	$729,418

(6) Line of Credit

The fund and certain other funds managed by MFS participate in a $1.1 billion unsecured committed line of credit, subject to a $1 billion sublimit, provided by a syndication of banks under a credit agreement. 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 higher of the Federal Reserve funds rate or one month LIBOR plus an agreed upon spread. 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. In addition, the fund and other funds managed by MFS have established unsecured uncommitted borrowing arrangements with certain banks for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the Federal Reserve funds rate plus an agreed upon spread. For the six months ended April 30, 2012, the funds commitment

fee and interest expense were $2,760 and $0, respectively, and are included in miscellaneous expense on the Statement of Operations.

(7) Transactions in Underlying Affiliated Funds-Affiliated Issuers

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and Shareholders of MFS Intermediate Income Trust:

We have reviewed the accompanying statement of assets and liabilities of MFS Intermediate Income Trust (the Trust), including the portfolio of investments, as of April 30, 2012, and the related statement of operations, changes in net assets, and financial highlights for the six-month period ended April 30, 2012. These interim financial statements and financial highlights are the responsibility of the Trusts management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying interim financial statements and financial highlights referred to above for them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the statement of changes in net assets for the year ended October 31, 2011, and the financial highlights for each of the five years in the period ended October 31, 2011, and in our report dated December 16, 2011, we expressed an unqualified opinion on such statement of changes in net assets and financial highlights.
