**Portfolio Turnover**

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 23% of the average value of its portfolio.

**Principal Investment Strategies**

Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in municipal securities, the interest on which is exempt from regular federal income tax. This policy is fundamental and may not be changed without shareholder approval. Municipal securities are debt obligations issued by or on behalf of states, territories and or possessions of the United States, and the District of Columbia and their political subdivisions, agencies or instrumentalities. The Fund may invest up to 100% of its assets (plus the amount of any borrowings for investment purposes) in municipal securities, the interest on which may be subject to the federal alternative minimum tax for individuals. In addition, the Fund may invest up to 20% of its assets in securities subject to regular federal income tax. The Fund may also invest in variable and floating rate demand instruments and tender option bonds.

The Fund may invest 25% or more of its total assets in certain types of municipal obligations (such as general obligations, municipal leases, principal only municipal investments, revenue bonds and industrial development bonds) and in one or more states, territories and economic sectors (such as housing, hospitals, healthcare facilities or utilities). At least 85% of the Fund's net assets normally will be invested in municipal obligations rated at least investment grade at the time of investment (which are those rated Baa3 or higher by Moody's Investors Service, Inc ("Moody's"), or BBB- or higher by either S&P Global Ratings ("S&P") or Fitch Ratings ("Fitch")) or, if unrated, determined by the Adviser to be of at least investment grade quality. The balance of net assets may be invested in municipal obligations rated below investment grade and in unrated municipal obligations considered to be of comparable quality by the Adviser ("junk bonds"). The Fund will not invest more than 5% of its net assets in obligations rated below B3 by Moody's, or B- by either S&P or Fitch, or in unrated obligations considered to be of comparable quality by the Adviser. For purposes of rating restrictions, if securities are rated differently by two or more rating agencies, the highest rating is used.

Under normal circumstances, the Fund intends to maintain a dollar-weighted average portfolio duration of less than three years; however, the Fund may invest in individual municipal obligations of any maturity. Duration measures the time-weighted expected cash flows of a fixed-income security, while maturity refers to the amount of time until a fixed-income security matures.

The Adviser's process for selecting obligations for purchase and sale emphasizes the creditworthiness of the issuer or other person obligated to repay the obligation and the relative value of the obligation in the market. In evaluating creditworthiness, the Adviser considers ratings assigned by rating agencies and generally performs additional credit and investment analysis. The portfolio managers also may trade securities to seek to minimize taxable capital gains to shareholders. A portion of the Fund's distributions generally will be subject to federal alternative minimum tax. The Fund may not be suitable for investors subject to the federal alternative minimum tax.

When deemed by the Adviser to be relevant to its evaluation of creditworthiness and when applicable information is available, the Adviser considers environmental, social and/or governance issues (referred to as ESG) which may impact the prospects of an issuer (or obligor) or financial performance of an obligation. When considered, one or more ESG issues are taken into account alongside other factors in the investment decision-making process and are not the sole determinant of whether an investment can be made or will remain in the Fund's portfolio.

The Fund may, but is not required to, use derivatives and similar instruments, such as residual interest bonds, futures contracts and options thereon, interest rate swaps and forward rate agreements, for a variety of purposes, including hedging, to seek total return or as a substitute for the purchase or sale of securities. Derivative instruments used by the Fund will be counted toward the Fund's 80% policy discussed above to the extent they have economic characteristics similar to the securities included within that policy.

**Principal Risks**

There is no assurance that the Fund will achieve its investment objective, and you can lose money investing in this Fund. Investments in the Fund involve risks and you should not rely on the Fund as a complete investment program. The relative significance of each risk factor summarized below may change over time and you should review each risk factor carefully because any one or more of these risks may result in losses to the Fund. The principal risks of investing in the Fund include:

Eaton Vance \| **Fund Summary**

Eaton Vance Short Duration Municipal Income ETF (Con't)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• **Municipals.** Because the Fund may invest in municipal securities (also referred to as municipal obligations), the Fund may be susceptible to political, legislative, economic, regulatory, tax or other factors affecting issuers of these municipal securities, such as state and local governments and their agencies. To the extent that the Fund invests in municipal securities of issuers in the same state or economic sector, it could be more sensitive to economic, business or political developments that affect such state or sector. Municipal securities and their issuers may be more susceptible to downgrade, loss of revenue, default and bankruptcy during periods of economic stress. Municipal securities also involve the risk that an issuer may call the securities for redemption, which could force the Fund to reinvest the proceeds at a lower rate of interest. While interest earned on municipal securities is generally not subject to regular federal income tax, any interest earned on taxable municipal securities is fully taxable at the federal level and may be subject to state and/or local income tax.

• **State and Municipal Project-Specific Risk.** To the extent that the Fund invests a significant portion of its assets in obligations issued in one or more states and/or  U.S. territories and in certain types of municipal or other obligations and/or in certain sectors, the value of Fund shares may be affected by events that adversely affect that state, U.S. territory, sector or type of obligation and may fluctuate more than that of a fund that invests more broadly. These developments or changes may include, among other things, legislative developments involving the financing of projects, judicial decisions regarding the validity of the projects or the means of financing such projects, shortages or price increases of materials needed for the project or declining needs for the projects as well as other developments that may adversely affect municipalities and other issuers of municipal securities located within the same state, such as natural disasters, health emergencies, and adverse economic, political or social environments.

• **Fixed-Income Securities.** Fixed-income securities are subject to the risk of the issuer's inability to meet principal and interest payments on its obligations (i.e., credit risk) and are subject to price volatility resulting from, among other things, interest rate sensitivity (i.e., interest rate risk), market perception of the creditworthiness of the issuer and general market liquidity (i.e., market risk). For example, a type of fixed-income securities in which the Fund may invest are corporate debt obligations. In addition to interest rate, credit and other risks, corporate debt obligations are also subject to factors directly related to the issuer, such as the credit rating of the corporation, the corporation's performance and perceptions of the corporation in the marketplace, and by factors not directly related to the issuer, such as general market liquidity, economic conditions and inflation. The Fund may face a heightened level of interest rate risk in times of monetary policy change and/or uncertainty, such as when the Federal Reserve Board adjusts a quantitative easing program and/or changes rates. A changing interest rate environment increases certain risks, including the potential for periods of volatility, increased redemptions, shortened durations (i.e., prepayment risk) and extended durations (i.e., extension risk). The Fund is not limited as to the maturities (when a debt security provides its final payment) or durations (measure of interest rate sensitivity of the securities) in which it may invest but, under normal circumstances, the Fund intends to maintain a dollar-weighted average portfolio duration of less than three years. Securities with longer durations are likely to be more sensitive to changes in interest rates, generally making them more volatile than securities with shorter durations. Lower rated fixed-income securities have greater volatility because there is less certainty that principal and interest payments will be made as scheduled. The Fund may be subject to certain liquidity risks that may result from the lack of an active market and the reduced number and capacity of traditional market participants to make a market in fixed-income securities.

• **Credit and Interest Rate Risk.** Credit risk refers to the possibility that the issuer or guarantor of a security, or counterparty to a transaction, will be unable or unwilling or perceived to be unable or unwilling to make interest payments and/or repay the principal on its debt or otherwise honor its obligations, including the risk of default. In such instances, the value of the Fund could decline and the Fund could lose money. If an issuer's, guarantor's or counterparty's financial condition worsens, the credit quality of the issuer, guarantor or counterparty may deteriorate. Credit ratings may not be an accurate assessment of financial condition, liquidity or credit risk. Although credit ratings may not accurately reflect the true credit risk of an instrument, a change in the credit rating of an instrument or an issuer, guarantor or counterparty, or the market's perception of the creditworthiness of an instrument or issuer, guarantor or counterparty can have a rapid, adverse effect on the instrument's value and liquidity and make it more difficult for the Fund to sell at an advantageous price or time. Interest rate risk refers to the decline in the value of a fixed-income security resulting from changes in the general level of interest rates. A wide variety of market and economic factors can cause interest rates to rise or fall, including central bank monetary policy, rising inflation, disinflation or deflation, and changes in general economic conditions. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up but the yield or income from new issuances of fixed-income securities generally decreases. Securities with longer durations will generally be more sensitive to changes in interest rates than securities with shorter durations. Fluctuations in interest rates may also affect the liquidity of and income generated by fixed-income instruments held by the Fund. The Fund may invest in variable and floating rate loans and other variable and floating rate securities. Although the value of these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk in times of monetary policy change and/or uncertainty, such as when the Federal Reserve Board adjusts a quantitative easing program and/or changes rates. Changing interest rates may have unpredictable effects on the markets and may detract from Fund performance. A changing interest rate environment increases certain risks, including the potential for periods of market volatility, increased redemptions, shortened durations (i.e., prepayment risk) and extended durations (i.e., extension risk).

Eaton Vance \| **Fund Summary**

Eaton Vance Short Duration Municipal Income ETF (Con't)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• **High Yield Securities ("Junk Bonds").** The Fund's investments in high yield securities expose it to increased risks, including a substantial degree of credit and default risks. High yield securities may be issued by companies that are restructuring, are smaller and less  creditworthy or are more highly leveraged or indebted than other companies or are financially distressed, and therefore they typically have more difficulty making scheduled payments of principal and interest than issuers of higher rated investments. High yield securities are subject to greater risk of loss (including substantial or total loss) of income and principal than higher rated securities and are considered speculative because of increased credit risk relative to higher rated fixed income investments. High yield securities are also subject to greater price volatility, including sudden and substantial decreases in price, and less liquidity than higher rated securities. High yield securities are particularly sensitive to adverse economic, market, industry or issuer-specific developments, which may result in an increased incidence of default. In the event of a default, the Fund may incur additional expenses to seek recovery or to negotiate new terms with a defaulting issuer.

• **Revenue Bonds.** Revenue bonds are municipal obligations that are secured by the revenue from a specific project. To the extent that such revenues do not materialize, the revenue bonds may not be repaid. If the Fund invests in revenue bonds that are issued by municipal issuers in the same economic sector, the Fund would be particularly susceptible to developments adversely affecting that sector. Revenue bonds historically have been subject to a greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project or other revenue source backing the project, rather than to the general taxing authority of the state or local government issuer of the obligations.

• **Tax-Exempt Variable Rate Demand Notes.** Tax-exempt variable rate demand notes are variable rate tax-exempt debt obligations that give investors the right to demand principal repayment. Due to cyclical supply and demand considerations, at times the yields on these obligations can exceed the yield on taxable money market obligations. The interest rate on these instruments may be reset daily, weekly or on some other reset period and may have a floor or ceiling on interest rate changes. The interest rate of a floating rate instrument may be based on a known lending rate, such as a bank's prime rate, and is reset whenever such rate is adjusted. The interest rate on a variable rate demand note is reset at specified intervals at a market rate. The Fund's ability to receive payments of principal and interest and other amounts in connection with debt obligations held by it will depend primarily on the financial condition of the issuer. The failure by the Fund to receive scheduled interest or principal payments on a debt obligation would adversely affect the income of the Fund and would likely reduce the value of its assets, which would be reflected in a reduction in the Fund's net asset value ("NAV").

• **Tender Option Bonds.** The risks of tender option bonds include the risk that the owner of such instrument may not be considered the owner for regular federal income tax purposes and thus will not be entitled to treat such interest as exempt from regular federal income tax. Additionally, the occurrence of certain defaults or a credit rating downgrade on the underlying security may impair the ability to tender the bond back to the third-party provider of the demand option, thus causing the bond to become illiquid.

• **Taxability Risk**.  Changes in tax laws or adverse determinations by the Internal Revenue Service ("IRS") may make the income from some municipal obligations taxable.

• **Liquidity.** The Fund may make investments that are less liquid, illiquid or restricted or that may become illiquid or less liquid in response to overall economic conditions or adverse investor perceptions, and which may entail greater risk than investments in other types of securities. These investments may be more difficult to value or sell, particularly in times of market turmoil, and there may be little trading in the secondary market available for particular securities. Liquidity risk may be magnified in a market where credit spread and interest rate volatility is rising and where investor redemptions from fixed-income funds may be higher than normal.  If the Fund is forced to sell an illiquid or restricted security to fund redemptions or for other cash needs, it may be forced to sell the security at a loss or for less than its fair value and may be unable to sell the security at all.

• **When-Issued Securities, Delayed Delivery Securities, TBAs and Forward Commitments.** The Fund may purchase or sell securities that it is entitled to receive on a when-issued, delayed delivery or through a forward commitment basis. For example, the Fund may invest in TBAs, which settle on a delayed delivery basis. These investments may result in a form of leverage and may increase volatility in the Fund's share price. In a TBA transaction, the seller agrees to deliver the MBS for an agreed upon price on an agreed upon future date, but makes no guarantee as to which or how many securities are to be delivered. Accordingly, the Fund's investments in TBAs are subject to risks such as failure of the counterparty to perform its obligation to deliver the security, the characteristics of a security delivered to the Fund may be less favorable than expected and the security the Fund buys will lose value prior to its delivery. The Fund's purchase of other securities on a when-issued, delayed delivery or through a forward commitment basis are subject to similar risks. When the Fund has sold a security on a when-issued, delayed delivery, or forward commitment basis, the Fund does not benefit if the value of the security appreciates above the sale price during the commitment period and the Fund is subject to failure of the counterparty to pay for the securities.

• **Market and Geopolitical Risk.** The value of your investment in the Fund is based on the values of the Fund's investments, which change due to economic, geopolitical and other events that affect the U.S. and global markets generally, as well as those that affect or are perceived or expected to affect particular regions, countries, industries, companies, issuers, sectors, asset classes or governments. These types of events may be sudden and unexpected, and could adversely affect the value (or income generated by) and liquidity of the Fund's investments, which may in turn impact the Fund's ability to sell securities and/or its ability to meet redemptions. The risks associated with these developments may be magnified if certain social, political, economic and other

Eaton Vance \| **Fund Summary**

Eaton Vance Short Duration Municipal Income ETF (Con't)

conditions and events (such as war, natural disasters or events, epidemics and pandemics, terrorism, conflicts, social unrest, recessions, inflation, interest rate changes, supply chain disruptions and the threat or actual imposition of tariffs, trade barriers and other protectionist or retaliatory measures) adversely interrupt or otherwise affect the global economy and financial markets. It is difficult to predict when events affecting the U.S. or global financial markets or economies may occur, the effects that such events may have and the duration of those effects (which may last for extended periods). These types of events may negatively impact broad segments of businesses and populations and have a significant and rapid negative impact on the performance or value of the Fund's investments, adversely affect and increase the volatility of the Fund's share price and exacerbate pre-existing risks to the Fund. The frequency and magnitude of resulting changes in the value of the Fund's investments cannot be predicted.

• **Active Management Risk.** In pursuing the Fund's investment objective, the Adviser has considerable leeway in deciding which investments to buy, hold or sell on a day-to-day basis, and which trading strategies to use. For example, the Adviser, in its discretion, may determine to use some permitted trading strategies while not using others. The success or failure of such decisions will affect the Fund's performance.

• **Portfolio Turnover.** Consistent with its investment policies, the Fund will purchase and sell securities without regard to the effect on portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs.

• **ETF Structure Risks.** 

*Authorized Participant Concentration Risk.* Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of intermediaries that act as authorized participants and none of these authorized participants is or will be obligated to engage in creation or redemption transactions. There can be no assurance that an active trading market for the Fund's shares will develop or be maintained. To the extent that these intermediaries exit the business or are unable to or choose not to proceed with creation and/or redemption orders with respect to the Fund, such as during periods of market stress, and no other authorized participant creates or redeems, shares may trade at a discount to NAV per share and possibly face trading halts and/or delisting. Authorized participant concentration risk may be heightened to the extent the Fund invests in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.

*Cash Transactions Risk*.** Unlike certain ETFs, the Fund may effect creations and redemptions in cash or partially in cash. Therefore, it may be required to sell portfolio securities and subsequently recognize gains on such sales that the Fund might not have recognized if it were to distribute portfolio securities in-kind. As such, investments in shares may be less tax-efficient than an investment in an ETF that distributes portfolio securities entirely in-kind.

*Trading Risk.* The market prices of shares are expected to fluctuate, in some cases materially, in response to changes in the Fund's NAV, the intra-day value of the Fund's holdings, and supply and demand for shares. The Adviser cannot predict whether shares will trade above, below or at their NAV. Disruptions to creations and redemptions, the existence of significant market volatility or potential lack of an active trading market for the shares (including through a trading halt), as well as other factors, may result in the shares trading significantly above (at a premium) or below (at a discount) to NAV or to the intraday value of the Fund's holdings. You may pay significantly more or receive significantly less than the Fund's NAV per share during periods when there is a significant premium or discount. Buying or selling shares in the secondary market may require paying brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost when seeking to buy or sell relatively small amounts of shares. In addition, the market price of shares, like the price of any exchange-traded security, includes a "bid-ask spread" charged by the market makers or other participants that trade the particular security. The spread of the Fund's shares varies over time based on the Fund's trading volume and market liquidity and may increase if the Fund's trading volume, the spread of the Fund's underlying securities, or market liquidity decrease.

Please see "Additional Information About Fund Investment Strategies and Related Risks" in the Fund's prospectus for a more detailed description of risks of investing in the Fund. Shares of the Fund are not bank deposits and are not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency.

**Performance Information**

As of the close of business on March 22, 2024, Morgan Stanley Institutional Fund Trust - Short Duration Municipal Income Portfolio (the "Predecessor Fund"), which operated as a mutual fund, was reorganized into the Fund ("Reorganization"). The Predecessor Fund's investment objective was substantially similar to the Fund's and the Predecessor Fund was managed in a manner that, in all material respects, complied with the investment guidelines and restrictions of the Fund. The Predecessor Fund was designated as the accounting survivor in the Reorganization. As a result, the Fund has assumed the Predecessor Fund's historical performance and the performance information shown below for the periods prior to March 22, 2024 reflects that of the Class IR shares of the Predecessor Fund, which had a different fee structure than the Fund. The performance of the Predecessor Fund for the periods prior to March 22, 2024 has not been restated to reflect the annual operating expenses of the Fund, which are lower than those of the Predecessor Fund. Past performance may have been different if the Fund's current fee structure had been in place during the period.

Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and after-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts ("IRAs"). After-tax returns may be higher than before-tax returns due to foreign tax credits and/or an assumed benefit from capital losses that would have been realized had Fund shares been sold at the end of the relevant periods, as applicable.

**Purchase and Sale of Fund Shares**

Individual shares of the Fund may only be purchased and sold in secondary market transactions through a broker or dealer at market price. Because shares trade at market prices, rather than NAV, shares of the Fund may trade at a price greater than NAV (i.e., a premium) or less than NAV (i.e., a discount).

You may incur costs attributable to the difference between the highest price a buyer is willing to pay for shares (bid) and the lowest price a seller is willing to accept for shares (ask) (the "bid-ask spread") when buying or selling shares in the secondary market.

Recent information, including information about the Fund's NAV, market price, premiums and discounts, and bid-ask spreads, is available on the Fund's website at www.eatonvance.com.

**Tax Information**

The Fund's distributions of interest on municipal obligations generally are not subject to regular federal income tax. The Fund's distributions from other portfolio securities may be subject to federal, state and/or local income taxes. Income derived from some municipal securities is subject to the federal alternative minimum tax. If the Fund makes any capital gain distributions, those distributions will normally be subject to federal and state income tax when they are paid, whether you take them in cash or reinvest them in Fund shares.

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you purchase shares of the Fund through a broker-dealer or financial intermediary (such as a bank), the Adviser and/or Foreside Fund Services, LLC (the "Distributor") may pay the financial intermediary for the sale of Fund shares and related services. These payments, which may be significant in amount, may create a conflict of interest by influencing the financial intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
