If you are a direct investor, you may elect to receive shareholder reports and other communications from the Fund electronically by signing up for e-Delivery at eatonvance.com/edelivery. If you own your shares through a financial intermediary (such as a broker-dealer or bank), you must contact your financial intermediary to sign up.

Commodity Futures Trading Commission Registration. Effective December 31, 2012, the Commodity Futures Trading Commission (“CFTC”) adopted certain regulatory changes that subject registered investment companies and advisers to regulation by the CFTC if a fund invests more than a prescribed level of its assets in certain CFTC-regulated instruments (including futures, certain options and swap agreements) or markets itself as providing investment exposure to such instruments. The investment adviser has claimed an exclusion from the definition of “commodity pool operator” under the Commodity Exchange Act with respect to its management of the Fund. Accordingly neither the Fund nor the adviser with respect to the operation of the Fund is subject to CFTC regulation. Because of its management of other strategies, the Fund’s adviser is registered with the CFTC as a commodity pool operator. The adviser is also registered as a commodity trading advisor.

Fund shares are not insured by the FDIC and are not deposits or other obligations of, or guaranteed by, any depository institution. Shares are subject to investment risks, including possible loss of principal invested.

This report must be preceded or accompanied by a current summary prospectus or prospectus. Before investing, investors should consider carefully the investment objective, risks, and charges and expenses of a mutual fund. This and other important information is contained in the summary prospectus and prospectus, which can be obtained from a financial intermediary. Prospective investors should read the prospectus carefully before investing. For further information, please call 1-800-260-0761.

Management’s Discussion of Fund Performance¹

Economic and Market Conditions

At the start of the 12-month period opened on March 1, 2019, investors appeared to be taking a “glass is half full” approach. Although U.S. manufacturing output and business investment remained weak — held back by slowing global growth and an on-again/off-again U.S.-China trade war — strong spending by U.S. consumers and dovish remarks by the U.S. Federal Reserve (the Fed) combined to lift investor sentiment. After four federal funds rate hikes in 2018, markets were projecting the Fed might lower rates in 2019 to stimulate the economy. U.S. unemployment, meanwhile, remained low and hiring remained strong.

As a result, U.S. stocks climbed in March and April 2019. Even a global stock pullback in May — sparked by heightened concerns about the U.S.-China trade dispute — proved to be temporary, and the U.S. stock rally resumed in June and July. After holding interest rates steady through the first half of the year, the Fed cut the federal funds rate on July 31, 2019 — its first reduction in over a decade — followed by two additional rate cuts in September and October to end the period at 1.50% – 1.75%.

After a mild downturn in August, U.S. equities rallied again in the final months of 2019, spurred by optimism about a U.S.- China trade détente and better-than-expected U.S. employment reports. The year ended with two events in December that did much to allay investor concerns about international trade and tariffs: passage of the United States-Mexico-Canada Agreement by the U.S. House of Representatives and the Trump administration’s agreement to a so-called “phase-one” trade deal with China.

In the last two months of the period, however, the outbreak of the coronavirus in China and its spread across the globe reversed much of the markets’ extraordinary gains in 2019. Consumer spending and industrial output in the world’s second-largest economy took a nosedive, as citizens were urged to stay home in an effort to contain the virus and factories delayed reopening until after the Chinese New Year.

As investors around the world worried about the negative effects on the global supply chain and global GDP, nearly all major equity indexes posted negative returns in January and February of 2020.

During the 12-month period ended February 29, 2020, the blue-chip Dow Jones Industrial Average^®2 returned 0.44%, while the broader U.S. equity market represented by the S&P 500^® Index returned 8.19%. The technology-laden Nasdaq Composite Index returned 14.94% during the period. Large-cap U.S. stocks, as measured by the S&P 500^® Index, generally outperformed their small-cap counterparts, as measured by the Russell 2000^® Index. As a group, growth stocks outpaced value stocks in both large- and small-cap categories as measured by the Russell 1000^® Growth and Value Indexes (large caps) and the Russell 2000^® Growth and Value Indexes (small caps).

Fund Performance

For the 12-month period ended February 29, 2020, Parametric Dividend Income Fund (the Fund) returned –4.76% for Investor Class shares at net asset value (NAV), underperforming its benchmark, the Russell 1000^® Value Index (the Index), which returned 0.54%.

The Fund is structured with a focus on broad diversification⁶ by both allocating a relatively equal weight among each of the Index’s 11 sectors; and allocating a relatively equal weight among select securities — those that rank the highest on Parametric’s combined low-risk/high-yield score — within each of the Index’s 11 sectors. The Fund’s equal-weighting approach may result in a portfolio with overweight positions in smaller sectors and underweight positions in larger sectors, as measured by market capitalization.

The Fund’s emphasis on diversification by targeting an equal- sector weighting detracted from performance relative to the Index during the period. An overweight exposure to the energy sector, which lagged the Index, was the largest sector-level detractor. An overweight allocation to the materials sector also detracted. Conversely, the Fund’s overweight allocation to the utilities sector contributed to relative results during the period.

In aggregate the Fund’s emphasis on diversification at the security level also detracted from performance relative to the Index. Security selections in the consumer discretionary sector made up the lion’s share of relative underperformance due, in part, to an overweight position in Six Flags Entertainment Corp., which plummeted after missing earnings and slashing its dividend; and an overweight position in Tupperware Brands Corp. (Tupperware), which declined over 40% during the period amid a first-quarter dividend cut and a third-quarter dividend suspension. By period- end, Tupperware was sold from the Fund.

Stock selections within the financials sector also detracted from relative results due, in part, to an overweight position in Franklin Resources, Inc. The asset manager’s stock price declined over 30% during the period as a result of poor asset flows and the CEO’s decision to step down.

Conversely, stock selections within the health care sector contributed to performance relative to the Index, partially due to the Fund’s underweight position in Pfizer, Inc., which declined in price amid lower-than-expected revenues and the announcement of a merger between the company’s Upjohn Co. business and generic drug firm Mylan NV. The Fund’s overweight positions in West Pharmaceutical Services, Inc. and Quest Diagnostics, Inc., both of which returned over 25% during the period, also contributed to relative results.

Past performance is no guarantee of future results. Returns are historical and are calculated by determining the percentage change in net asset value (NAV) or offering price (as applicable) with all distributions reinvested. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Performance for periods less than or equal to one year is cumulative. Performance is for the stated time period only; due to market volatility, current Fund performance may be lower or higher than the quoted return.

Fund Expenses

Example:  As a Fund shareholder, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchases and redemption fees (if applicable); and (2) ongoing costs, including management fees; distribution and/or service fees; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of Fund investing 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 (September 1, 2019 – February 29, 2020).

Actual Expenses:  The first section of the table below provides information about actual account values and actual expenses. You may use the information in this section, 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 section 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 section of the table below provides information about hypothetical account values and hypothetical expenses based on the actual Fund expense ratio and an assumed rate of return of 5% per year (before expenses), which is not the actual Fund 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 your 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 (if applicable). Therefore, the second section of 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 be higher.

	Beginning Account Value (9/1/19)		Ending Account Value (2/29/20)		Expenses Paid During Period* (9/1/19 – 2/29/20)			Annualized Expense Ratio
Actual
Investor Class	$	1,000.00	$	961.90	$	3.17	**		0.65	%
Institutional Class	$	1,000.00	$	962.40	$	1.95	**		0.40	%
Hypothetical
(5% return per year before expenses)
Investor Class	$	1,000.00	$	1,021.60	$	3.27	**		0.65	%
Institutional Class	$	1,000.00	$	1,022.90	$	2.01	**		0.40	%

* Expenses are equal to the Fund’s annualized expense ratio for the indicated Class, multiplied by the average account value over the period, multiplied by 182/366 (to reflect the one-half year period). The Example assumes that the $1,000 was invested at the net asset value per share determined at the close of business on August 31, 2019.

** Absent an allocation of certain expenses to affiliates, expenses would be higher.

Notes to Financial Statements

1  Significant Accounting Policies

Parametric Dividend Income Fund (the Fund) is a diversified series of Eaton Vance Mutual Funds Trust (the Trust). The Trust is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. The Fund’s investment objective is total return and current income. The Fund offers Investor Class and Institutional Class shares, which are offered at net asset value and are not subject to a sales charge. Each class represents a pro-rata interest in the Fund, but votes separately on class-specific matters and (as noted below) is subject to different expenses. Realized and unrealized gains and losses and net investment income and losses, other than class-specific expenses, are allocated daily to each class of shares based on the relative net assets of each class to the total net assets of the Fund. Each class of shares differs in its distribution plan and certain other class-specific expenses.

The following is a summary of significant accounting policies of the Fund. The policies are in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). The Fund is an investment company and follows accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946.

A  Investment Valuation — The following methodologies are used to determine the market value or fair value of investments.

Equity Securities. Equity securities listed on a U.S. securities exchange generally are valued at the last sale or closing price on the day of valuation or, if no sales took place on such date, at the mean between the closing bid and ask prices on the exchange where such securities are principally traded. Equity securities listed on the NASDAQ Global or Global Select Market generally are valued at the NASDAQ official closing price. Unlisted or listed securities for which closing sales prices or closing quotations are not available are valued at the mean between the latest available bid and ask prices.

Affiliated Fund. The Fund may invest in Eaton Vance Cash Reserves Fund, LLC (Cash Reserves Fund), an affiliated investment company managed by Eaton Vance Management (EVM). While Cash Reserves Fund is not a registered money market mutual fund, it conducts all of its investment activities in accordance with the requirements of Rule 2a-7 under the 1940 Act. Investments in Cash Reserves Fund are valued at the closing net asset value per unit on the valuation day. Cash Reserves Fund generally values its investment securities based on available market quotations provided by a third party pricing service.

Fair Valuation. Investments for which valuations or market quotations are not readily available or are deemed unreliable are valued at fair value using methods determined in good faith by or at the direction of the Trustees of the Fund in a manner that most fairly reflects the security’s “fair value”, which is the amount that the Fund might reasonably expect to receive for the security upon its current sale in the ordinary course. Each such determination is based on a consideration of relevant factors, which are likely to vary from one pricing context to another. These factors may include, but are not limited to, the type of security, the existence of any contractual restrictions on the security’s disposition, the price and extent of public trading in similar securities of the issuer or of comparable companies or entities, quotations or relevant information obtained from broker/dealers or other market participants, information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities), an analysis of the company’s or entity’s financial statements, and an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold.

B  Investment Transactions — Investment transactions for financial statement purposes are accounted for on a trade date basis. Realized gains and losses on investments sold are determined on the basis of identified cost.

C  Income — Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities.

D  Federal Taxes — The Fund’s policy is to comply with the provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute to shareholders each year substantially all of its net investment income, and all or substantially all of its net realized capital gains. Accordingly, no provision for federal income or excise tax is necessary.

As of February 29, 2020, the Fund had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. The Fund files a U.S. federal income tax return annually after its fiscal year-end, which is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.

E  Expenses — The majority of expenses of the Trust are directly identifiable to an individual fund. Expenses which are not readily identifiable to a specific fund are allocated taking into consideration, among other things, the nature and type of expense and the relative size of the funds.

F  Use of Estimates — The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expense during the reporting period. Actual results could differ from those estimates.

G  Indemnifications — Under the Trust’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. Under Massachusetts law, if certain conditions prevail, shareholders of a Massachusetts business trust (such as the Trust) could be deemed to have personal liability for the obligations of the Trust. However, the Trust’s Declaration of Trust contains an express disclaimer of liability on the part of Fund shareholders and the By-laws provide that the Trust shall assume, upon request by the shareholder, the defense on behalf of any Fund shareholders. Moreover, the By-laws also provide for indemnification out of Fund property of any shareholder held personally liable solely by reason of being or having been a shareholder for all loss or expense arising from such liability. 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 arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

2  Distributions to Shareholders and Income Tax Information

It is the present policy of the Fund to make quarterly distributions of all or substantially all of its net investment income and to distribute annually all or substantially all of its net realized capital gains. Distributions to shareholders are recorded on the ex-dividend date. Distributions are declared separately for each class of shares. Shareholders may reinvest income and capital gain distributions in additional shares of the same class of the Fund at the net asset value as of the ex-dividend date or, at the election of the shareholder, receive distributions in cash. Distributions to shareholders are determined in accordance with income tax regulations, which may differ from U.S. GAAP. As required by U.S. GAAP, only distributions in excess of tax basis earnings and profits are reported in the financial statements as a return of capital. Permanent differences between book and tax accounting relating to distributions are reclassified to paid-in capital. For tax purposes, distributions from short-term capital gains are considered to be from ordinary income.

The tax character of distributions declared for the years ended February 29, 2020 and February 28, 2019 was as follows:

	Year Ended February 29, 2020		Year Ended February 28, 2019
Ordinary income	$	1,539,004	$	1,839,004
Long-term capital gains	$	31,613	$	911,702

During the year ended February 29, 2020, accumulated loss was increased by $30,723 and paid-in capital was increased by $30,723 due to the Fund’s use of equalization accounting. Tax equalization accounting allows the Fund to treat as a distribution that portion of redemption proceeds representing a redeeming shareholder’s portion of undistributed taxable income and net capital gains. These reclassifications had no effect on the net assets or net asset value per share of the Fund.

As of February 29, 2020, the components of distributable earnings (accumulated loss) on a tax basis were as follows:

Undistributed ordinary income	$	196,812
Deferred capital losses	$	(1,036,119	)
Net unrealized depreciation	$	(1,458,524	)

At February 29, 2020, the Fund, for federal income tax purposes, had deferred capital losses of $1,036,119 which would reduce its taxable income arising from future net realized gains on investment transactions, if any, to the extent permitted by the Internal Revenue Code, and thus would reduce the amount of distributions to shareholders, which would otherwise be necessary to relieve the Fund of any liability for federal income or excise tax. The deferred capital losses are treated as arising on the first day of the Fund’s next taxable year and retain the same short-term or long-term character as when originally deferred. Of the deferred capital losses at February 29, 2020, $786,480 are short-term and $249,639 are long-term.

The cost and unrealized appreciation (depreciation) of investments of the Fund at February 29, 2020, as determined on a federal income tax basis, were as follows:

Aggregate cost	$	48,159,198
Gross unrealized appreciation	$	2,531,916
Gross unrealized depreciation		(3,990,440	)
Net unrealized depreciation	$	(1,458,524	)

3  Investment Adviser and Administration Fee and Other Transactions with Affiliates

The investment adviser and administration fee is earned by EVM as compensation for investment advisory and administrative services rendered to the Fund. Pursuant to the investment advisory and administration agreement and subsequent fee reduction agreement between the Fund and EVM, the fee is computed at an annual rate of 0.30% of the Fund’s average daily net assets up to $1 billion and is payable monthly. On net assets of $1 billion and over, the annual fee is reduced. The fee reduction cannot be terminated or reduced without the approval of a majority vote of the Trustees of the Fund who are not interested persons of EVM or the Fund and by the vote of a majority of shareholders. For the year ended February 29, 2020, the investment adviser and administration fee amounted to $169,155 or 0.30% of the Fund’s average daily net assets. Pursuant to a sub-advisory agreement, EVM has delegated the investment management of the Fund to Parametric Portfolio Associates LLC (Parametric), a wholly-owned indirect subsidiary of Eaton Vance Corp. EVM pays Parametric a portion of its investment adviser and administration fee for sub-advisory services provided to the Fund. The Fund invests its cash in Cash Reserves Fund. EVM does not currently receive a fee for advisory services provided to Cash Reserves Fund.

Notes to Financial Statements — continued

EVM and Parametric have agreed to reimburse the Fund’s expenses to the extent that total annual operating expenses (relating to ordinary operating expenses only) exceed 0.65% and 0.40% of the Fund’s average daily net assets for Investor Class and Institutional Class, respectively. This agreement may be changed or terminated after June 30, 2020. Pursuant to this agreement, EVM and Parametric were allocated $96,011 in total of the Fund’s operating expenses for the year ended February 29, 2020.

EVM provides sub-transfer agency and related services to the Fund pursuant to a Sub-Transfer Agency Support Services Agreement. For the year ended February 29, 2020, EVM earned $973 from the Fund pursuant to such agreement, which is included in transfer and dividend disbursing agent fees on the Statement of Operations. Eaton Vance Distributors, Inc. (EVD), an affiliate of EVM and the Fund’s principal underwriter, received distribution and service fees from Investor Class shares (see Note 4).

Trustees and officers of the Fund who are members of EVM’s organization receive remuneration for their services to the Fund out of the investment adviser and administration fee. Trustees of the Fund who are not affiliated with EVM may elect to defer receipt of all or a percentage of their annual fees in accordance with the terms of the Trustees Deferred Compensation Plan. For the year ended February 29, 2020, no significant amounts have been deferred. Certain officers and Trustees of the Fund are officers of EVM.

4  Distribution Plan

The Fund has in effect a distribution plan for Investor Class shares (Investor Class Plan) pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Investor Class Plan, the Fund pays EVD a distribution and service fee of 0.25% per annum of its average daily net assets attributable to Investor Class shares for distribution services and facilities provided to the Fund by EVD, as well as for personal services and/or the maintenance of shareholder accounts. Distribution and service fees paid or accrued to EVD for the year ended February 29, 2020 amounted to $13,206 for Investor Class shares.

Distribution and service fees are subject to the limitations contained in the Financial Industry Regulatory Authority Rule 2341(d).

5  Purchases and Sales of Investments

Purchases and sales of investments, other than short-term obligations, aggregated $28,011,469 and $35,644,905, respectively, for the year ended February 29, 2020.

6  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 (without par value). Such shares may be issued in a number of different series (such as the Fund) and classes. Transactions in Fund shares were as follows:

Investor Class	Year Ended February 29, 2020			Year Ended February 28, 2019
Sales		39,503			245,182
Issued to shareholders electing to receive payments of distributions in Fund shares		10,611			25,777
Redemptions		(260,637	)		(194,519	)

Redemptions		(1,360,642	)		(1,592,576	)
Net increase (decrease)		(383,736	)		2,350,324

7  Line of Credit

The Fund participates with other portfolios and funds managed by EVM and its affiliates in an $800 million unsecured line of credit agreement with a group of banks, which is in effect through October 27, 2020. In connection with the renewal of the agreement on October 29, 2019, funds managed by

Notes to Financial Statements — continued

Calvert Research and Management, an affiliate of EVM, were added as participating funds to the agreement and the borrowing limit was increased from $625 million. Borrowings are made by the Fund solely for temporary purposes related to redemptions and other short-term cash needs. Interest is charged to the Fund based on its borrowings at an amount above either the Eurodollar rate or Federal Funds rate. In addition, a fee computed at an annual rate of 0.15% on the daily unused portion of the line of credit is allocated among the participating portfolios and funds at the end of each quarter. Because the line of credit is not available exclusively to the Fund, it may be unable to borrow some or all of its requested amounts at any particular time. The Fund did not have any significant borrowings or allocated fees during the year ended February 29, 2020.

8  Securities Lending Agreement

The Fund has established a securities lending agreement with State Street Bank and Trust Company (SSBT) as securities lending agent in which the Fund lends portfolio securities to qualified borrowers in exchange for collateral consisting of either cash or securities issued or guaranteed by the U.S. government or its agencies or instrumentalities in an amount at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is delivered to the Fund on the next business day. Cash collateral is invested in the State Street Navigator Securities Lending Government Money Market Portfolio, a money market fund registered under the 1940 Act. The Fund earns interest on the amount invested but it must pay (and at times receive from) the broker a loan rebate fee computed as a varying percentage of the collateral received. For security loans secured by non-cash collateral, the Fund earns a negotiated lending fee from the borrower. A portion of the income earned by the Fund from its investment of cash collateral, net of rebate fees, and lending fees received is allocated to SSBT for its services as lending agent and the portion allocated to the Fund is presented as securities lending income, net on the Statement of Operations. Non-cash collateral is held by the lending agent on behalf of the Fund and cannot be sold or re-pledged by the Fund; accordingly, such collateral is not reflected in the Statement of Assets and Liabilities.

The Fund is subject to possible delay in the recovery of loaned securities. Pursuant to the securities lending agreement, SSBT has provided indemnification to the Fund in the event of default by a borrower with respect to a loan. The Fund bears the risk of loss with respect to the investment of cash collateral.

At February 29, 2020, the value of the securities loaned (all common stock) and the value of the collateral received, which exceeded the value of the securities loaned, amounted to $1,101,025 and $1,151,312, respectively. Collateral received was comprised of U.S. government and/or agencies securities of $1,151,312. The securities lending transactions have no contractual maturity date and each of the Fund and borrower has the option to terminate a loan at any time.

9  Investments in Affiliated Funds

At February 29, 2020, the value of the Fund’s investment in affiliated funds was $233,238, which represents 0.5% of the Fund’s net assets. Transactions in affiliated funds by the Fund for the year ended February 29, 2020 were as follows:

Name of affiliated fund	Value, beginning of period		Purchases		Sales proceeds			Net realized gain (loss)		Change in unrealized appreciation (depreciation)			Value, end of period		Dividend income		Units, end of period
Short-Term Investments
Eaton Vance Cash Reserves Fund, LLC	$	287,433	$	13,391,625	$	(13,445,952	)	$	137	$	(5	)	$	233,238	$	5,412		233,191

10  Fair Value Measurements

Under generally accepted accounting principles for fair value measurements, a three-tier hierarchy to prioritize the assumptions, referred to as inputs, is used in valuation techniques to measure fair value. The three-tier hierarchy of inputs is summarized in the three broad levels listed below.

• Level 1 – quoted prices in active markets for identical investments

• Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

• Level 3 – significant unobservable inputs (including a fund’s own assumptions in determining the fair value of investments)

In cases where the inputs used to measure fair value fall in different levels of the fair value hierarchy, the level disclosed is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

At February 29, 2020, the hierarchy of inputs used in valuing the Fund’s investments, which are carried at value, were as follows:

Asset Description	Level 1			Level 2		Level 3		Total
Common Stocks	$	46,467,436	*	$	—	$	—	$	46,467,436
Short-Term Investments		—			233,238		—		233,238
Total Investments	$	46,467,436		$	233,238	$	—	$	46,700,674

* The level classification by major category of investments is the same as the category presentation in the Portfolio of Investments.

11  Subsequent Event

An outbreak of respiratory disease caused by a novel coronavirus that was first detected in China in December 2019 has continued to spread rapidly internationally. This coronavirus has resulted in closing borders, enhanced health screenings, changes to healthcare service preparation and delivery, quarantines, cancellations, disruptions to supply chains and customer activity, as well as general concern and uncertainty, and in March 2020, a declaration of a national emergency in the United States. The near-term impact of this coronavirus has resulted in substantial market volatility. The ultimate economic and market impact of this coronavirus cannot be reliably estimated as of April 17, 2020, the date these financial statements were issued.

Report of Independent Registered Public Accounting Firm

To the Trustees of Eaton Vance Mutual Funds Trust and Shareholders of Parametric Dividend Income Fund:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of Parametric Dividend Income Fund (the “Fund”) (one of the funds constituting Eaton Vance Mutual Funds Trust), including the portfolio of investments, as of February 29, 2020, 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, the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of February 29, 2020, and 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 the 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.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. 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, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of February 29, 2020, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Delivery of Shareholder Documents.  The Securities and Exchange Commission (SEC) permits funds to deliver only one copy of shareholder documents, including prospectuses, proxy statements and shareholder reports, to fund investors with multiple accounts at the same residential or post office box address. This practice is often called “householding” and it helps eliminate duplicate mailings to shareholders. Eaton Vance, or your financial intermediary, may household the mailing of your documents indefinitely unless you instruct Eaton Vance, or your financial intermediary, otherwise. If you would prefer that your Eaton Vance documents not be householded, please contact Eaton Vance at 1-800-260-0761, or contact your financial intermediary. Your instructions that householding not apply to delivery of your Eaton Vance documents will typically be effective within 30 days of receipt by Eaton Vance or your financial intermediary.

The Form N-PORT will be available on the Eaton Vance website at www.eatonvance.com, by calling Eaton Vance at 1-800-260-0761 or in the EDGAR database on the SEC’s website at www.sec.gov.

(e)(1) The registrant’s audit committee has adopted policies and procedures relating to the pre-approval of services provided by the registrant’s principal accountant (the “Pre-Approval Policies”). The Pre-Approval Policies establish a framework intended to assist the audit committee in the proper discharge of its pre-approval responsibilities. As a general matter, the Pre-Approval Policies (i) specify certain types of audit, audit-related, tax, and other services determined to be pre-approved by the audit committee; and (ii) delineate specific procedures governing the mechanics of the pre-approval process, including the approval and monitoring of audit and non-audit service fees. Unless a service is specifically pre-approved under the Pre-Approval Policies, it must be separately pre-approved by the audit committee.

The Pre-Approval Policies and the types of audit and non-audit services pre-approved therein must be reviewed and ratified by the registrant’s audit committee at least annually. The registrant’s audit committee maintains full responsibility for the appointment, compensation, and oversight of the work of the registrant’s principal accountant.
