IMPORTANT NOTICE
REGARDING DELIVERY OF
SHAREHOLDER DOCUMENTS

The Securities and Exchange Commission 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 adviser, may household the mailing of
your documents indefinitely unless you instruct Eaton Vance, or your
financial adviser, otherwise.

If you would prefer that your Eaton Vance documents not be householded,
please contact Eaton Vance at 1-800-262-1122, or contact your financial
adviser.

Your instructions that householding not apply to delivery of your Eaton
Vance documents will be effective within 30 days of receipt by Eaton
Vance or your financial adviser.

- -----------------------------------------------------------------------
From time to time, funds are required to vote proxies related to the
securities held by the funds. The Eaton Vance Funds or their underlying
Portfolios vote proxies according to a set of policies and procedures
approved by the Funds' and Portfolios' Boards. You may obtain a
description of these policies and procedures without charge, upon
request, by calling 1-800-262-1122. This description is also available on

INVESTMENT UPDATE

[PHOTO WITH CAPTION "Walter Row, Investment Team Leader"]

An interview with Walter Row, Investment Team Leader, Equity Research
Fund

Q:  Walter, can you share some thoughts on what happened in the stock
markets over the last 12 months?

A:  Equity markets have enjoyed positive returns for the 12 months ending
October 31, 2003. After several years of disappointing returns, several
factors have combined to help drive stocks higher over the past year.
A strengthening U.S. economy and an improved outlook for corporate
earnings were the key drivers of equity market performance. Also, the
fact that interest rates and inflation remained low by historical
standards also supported higher equity prices.


Five Largest Sector Positions +

Financial services -- 9.5%
Electronics/Semiconductors -- 7.7%
Banks -- 7.1%
Pharmaceuticals -- 6.0%
Oil and Gas -- 5.5%

+ Sector positions are subject to change due to active management.
* It is not possible to invest directly in an Index.


Q:  While the Fund posted a solid double-digit return over the past
year, its rate of increase lagged its benchmark, the S&P 500.* Can you
comment on this?

A:  We are pleased with the Fund's performance over the past year. By
staying focused on stock selection we were able to deliver strong
returns for our shareholders. Our commitment to stock selection also
contributed to our underperformance relative to our benchmark. In the
early phases of an equity market recovery, it is not uncommon for many
of the best performing stocks to be found among lower-priced,
lower-quality issues. Quite often, many of the stocks enjoying the
strongest rebounds are the same stocks that suffered the sharpest losses
during the market's decline. That has been very much the case over the
past year. Because the stock selection for the Fund is based on
fundamental research, the Fund has generally avoided owning many of
these stocks.

Q:  Have there been any changes in the way the Fund is managed?

A:  No, we still seek to achieve long-term capital appreciation by
investing in a diversified portfolio of equity securities. Securities
held in the Fund are selected by a team of investment analysts that make
up the Eaton Vance equity research group. Each analyst is responsible
for stock selection within his or her area of expertise and allocation
for the Fund intends to maintain investments in all or substantially all
of the market sectors represented in the S&P 500.*

Eaton Vance Equity Research Fund as of October 31, 2003

INVESTMENT UPDATE Cont'd

Fundamental research remained the cornerstone of our Fund. Our analyst
team conducts extensive research into a company's financials while
additionally considering broad, macro-economic trends that may influence
a company's growth. We believe this approach allows our analysts to see
the big picture before committing to buy any security.

Q:  What positively benefited the Fund over the past year?

A:  The Fund was successful in its allocations in the financial services
and banking sectors, which saw improving earnings based on the overall
economic recovery and the continuing low interest rate environment.
Technology related stocks in general have enjoyed some of the strongest
gains over the past year. Our careful selections in electronics -
semiconductors helped add to our Fund's overall performance for the
year. Consumer related stocks (consumer non-durables and retail) also
performed well as consumer confidence rose on the back of an improving
economy.

Q:  What negatively impacted Fund performance over the past year?

A:  If measured against our benchmark, the Fund was impacted more by what
securities it did not hold over the time period, than securities held by
the Fund. Our strict research requirements eliminated many stocks from
the start. Most of the more spectacular gains in the market over the
past year came from lower quality issues. These are stocks that would be
filtered out of the Fund's investment pool based on our commitment to
disciplined fundamental research.

Q:  What is your outlook for the Fund?

A:  We believe the companies now held in the Fund are attractively valued
and hold positions of strength in their prospective industries. Our
analyst team is a highly disciplined group who bring an average of 15
years investment experience to the task of selecting stocks. Regardless
of short-term market fluctuations, our analysts focus on rigorous
fundamental research which we feel is the true driver of long-term
performance.

  The chart compares the Fund's total return with that of the S&P 500
  Composite Index, a broad-based, unmanaged market index of common
  stocks commonly used as a measure of U.S. stock market performance.
  Returns are calculated by determining the percentage change in net
  asset value (NAV) with all distributions reinvested. The graph and
  performance table do not reflect the deduction of taxes that a
  shareholder would pay on Fund distributions or the redemption of Fund
  shares. The Index's return uses net dividends, which reflect the
  deduction of withholding taxes. The lines on the chart represent the
  total returns of $10,000 hypothetical investments in the Fund and the
  Index. The Index's total return does not reflect any commissions or
  expenses that would have been incurred if an investor individually
  purchased or sold the securities represented in the Index. It is not
  possible to invest directly in an Index.

1 Returns are historical and are calculated by determining the
  percentage change in net asset value with all distributions
  reinvested. SEC returns reflect the maximum 5.75% sales charge. 2Ten
  largest holdings accounted for 19.4% of the Fund's net assets.
  Holdings are subject to change.

  Past performance is no guarantee of future results. Investment return
  and principal value will fluctuate so that shares, when redeemed, may
  be worth more or less than their original cost.

NOTES TO FINANCIAL STATEMENTS

1 Significant Accounting Policies
- --------------------------------------------------------------------------
Eaton Vance Equity Research Fund (the Fund) is a diversified series of
Eaton Vance Mutual Funds Trust (the Trust) and commenced operations on
November 1, 2001. The Trust is an entity of the type commonly known as a
Massachusetts business trust and is registered under the Investment Company
Act of 1940 (the 1940 Act), as amended, as an open-end management
investment company. The Fund's investment objective is to achieve long-term
capital appreciation by investing in a diversified portfolio of equity
securities. The following is a summary of significant accounting policies
consistently followed by the Fund in the preparation of its financial
statements. The policies are in conformity with accounting principles
generally accepted in the United States of America.

A  Investment Valuations -- Securities listed on foreign or U.S. securities
exchanges are valued at closing sales prices or, if there were no sales, at
the mean between the closing bid and asked prices on the exchange where
such securities are principally traded or on such National Market System.
Marketable securities listed in the NASDAQ National Market System are
valued at the NASDAQ official closing price. Unlisted or listed securities
for which closing sales prices are not available are valued at the mean
between the latest bid and asked prices. Futures positions on securities or
currencies are generally valued at closing settlement prices. Short-term
debt securities with a remaining maturity of 60 days or less are valued at
amortized cost. If securities were acquired with a remaining maturity of
more than 60 days, their amortized cost value will be based on their value
on the sixty-first day prior to maturity. Other fixed income and debt
securities, including listed securities and securities for which price
quotations are available, will normally be valued on the basis of
valuations furnished by a pricing service. Securities for which market
quotations are unavailable are valued at fair value as determined in good
faith by or at the direction of the Trustees.

B  Income -- Interest income is determined on the basis of interest
accrued, adjusted for amortization of premium or accretion of discount.
Dividend income is recorded on the ex-dividend date for dividends received
in cash and/or securities. However, if the ex-dividend date has passed,
certain dividends from foreign securities are recorded as the Fund is
informed of the ex-dividend date.

C  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 all of its taxable income,
including any net realized gain on investments. Accordingly, no provision
for federal income or excise tax is necessary. At October 31, 2003, the
Fund, for Federal income tax purposes, had a capital loss carryover of
$67,674, which will reduce the Fund's taxable income arising from future
net realized gains on investments, if any, to the extent permitted by the
Internal Revenue Code, and thus will reduce the amount of the distributions
to shareholders which would otherwise be necessary to relieve the Fund of
any liability for federal income or excise tax. Such capital loss carryover
will expire on October 31, 2010 ($57,732) and October 31, 2011 ($9,942). At
October 31, 2003, the Fund's undistributed ordinary income on a tax basis
was $641.

D  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.

E  Expense Reduction -- Investors Bank & Trust Company (IBT) serves as
custodian to the Fund. Pursuant to the custodian agreement, IBT receives a
fee reduced by credits which are determined based on the average daily cash
balance the Fund maintains with IBT. All significant credit balances used
to reduce the Fund's custodian fees are reported as a reduction of total
expenses in the Statement of Operations. For the year ended October 31,
2003, no credit balances were used to reduce the Fund's custodian fee.

F  Use of Estimates -- The preparation of financial statements in
conformity with accounting principles generally accepted in the United
States of America 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  Other -- Investment transactions are accounted for on a trade date
basis. Realized gains and losses are computed on the specific
identification of the securities sold.


2 Distributions to Shareholders
- --------------------------------------------------------------------------
It is the present policy of the Fund to distribute semi-annually
substantially all of the net investment income of the Fund and to
distribute, at least annually, substantially all of its net realized
capital gains, if any. Distributions are paid in the form of additional
shares of the Fund or, at the election of the shareholder, in cash.
Shareholders may reinvest capital gain distributions in additional shares
of the Fund at the net asset value as of the ex-dividend date. The Fund
distinguishes between distributions on a tax basis and a financial
reporting basis. Permanent differences between book and tax accounting
relating to distributions are reclassified to paid-in capital.

4 Investment Adviser Fee and

The investment adviser fee is earned by EVM as compensation for management
and investment advisory services rendered to the Fund. EVM receives a
monthly advisory fee equal to 0.65% of the average daily net assets of the
Fund up to $500 million and at reduced rates as daily net assets exceed
that level. For the year ended October 31, 2003, the fee amounted to
$5,348, all of which was waived. An administrative fee is earned by EVM as
compensation for administering certain business affairs of the Fund. The
fee is equal to 0.15% of the average daily net assets of the Fund. For year
ended October 31, 2003, the fee amounted to $1,217, all of which was
waived. To enhance the net investment income of the Fund, EVM was allocated
$36,359 of the Fund's operating expenses. EVM serves as the sub-transfer
agent of the Fund and receives an aggregate fee based on the actual
expenses incurred by EVM in the performance of those services. For the year
ended October 31, 2003, EVM earned $66 in sub-transfer agent fees from the
Fund.

Except as to Trustees of the Fund who are not members of EVM's
organization, officers and Trustees receive remuneration for their services
to the Fund out of such investment adviser fee. Trustees of the Fund who
are not affiliated with the Investment Adviser 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 October 31,
2003, no significant amounts have been deferred. Certain officers and
Trustees of the Fund are officers of the above organization.


5 Service Plan
- --------------------------------------------------------------------------
The Trust has in effect a Service Plan (the Plan) for the Fund. The Plan
authorizes the Fund to make payments of service fees to EVD, investment
dealers and other persons in amounts equal to 0.25% of the Fund's average
daily net assets. Service fee payments are made for personal services
and/or the maintenance of shareholder accounts. Service fees for the year
ended October 31, 2003 amounted to $2,034.

including the portfolio of investments, and the related statements of
operations and of changes in net assets and the financial highlights

principles generally accepted in the United States of America. These
financial statements and financial highlights (hereafter referred to as
