Investment Objective

The Fund's investment objective is total return.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. Investors may also pay commissions or other fees to their financial intermediary, which are not reflected below. You may qualify for a reduced sales charge on purchases of Class A if you invest, or agree to invest over a 13-month period, at least $50,000 in Eaton Vance Funds. Certain financial intermediaries also may offer variations in Fund sales charges to their customers as described in Appendix A – Financial Intermediary Sales Charge Variations in this Prospectus. More information about these and other discounts is available from your financial intermediary and in Sales Charges beginning on page 40 of this Prospectus and page 22 of the Fund’s Statement of Additional Information.

Shareholder Fees (fees paid directly from your investment)	Class A	Class C	Class I
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	5.75%	None	None
Maximum Deferred Sales Charge (Load) (as a percentage of the lower of net asset value at time of purchase or redemption)	None	1.00%	None

Annual Fund Operating Expenses (expenses you pay each year as a percentage of the value of your investment)	Class A	Class C	Class I
Management Fees	0.83%	0.83%	0.83%
Distribution and Service (12b-1) Fees	0.25%	1.00%	None
Other Expenses	0.10%	0.10%	0.10%
Acquired Fund Fees and Expenses	0.23%	0.23%	0.23%
Total Annual Fund Operating Expenses	1.41%	2.16%	1.16%

Example. This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year, that the operating expenses remain the same and that any expense reimbursement arrangement remains in place for the contractual period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	Expenses with Redemption				Expenses without Redemption
	1 Year	3 Years	5 Years	10 Years	1 Year	3 Years	5 Years	10 Years
Class A shares	$710	$996	$1,302	$2,169	$710	$996	$1,302	$2,169
Class C shares	$319	$676	$1,159	$2,303	$219	$676	$1,159	$2,303
Class I shares	$118	$368	$638	$1,409	$118	$368	$638	$1,409

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” the 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 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 63% of the average value of its portfolio.

Eaton Vance Richard Bernstein Funds3Prospectus dated January 1, 2022

Principal Investment Strategies

In seeking its investment objective, the Fund has the flexibility to allocate its assets in markets around the world and among various asset classes, including equity, fixed-income, commodity, currency and cash investments.

The Fund is managed in a macro-driven, top-down style that emphasizes and de-emphasizes various global market segments and asset classes at different times. Market segments chosen for emphasis and/or de-emphasis may vary from general market consensus views and the Fund may at times seek to identify areas where, in the sub-adviser’s opinion, there is scarcity of capital and/or potentially overlooked investment opportunities. Exposures will vary among asset classes based on the sub-adviser’s assessment of a range of proprietary and non-proprietary quantitative indicators and the firm’s macro-economic analysis and judgment. In using this “beta” management style, it is expected that the macro-economic analysis will evolve over time and may include consideration of the following: historical risk and return characteristics; global market valuations; global yield curves; asset class, regional, and country correlations; profit cycle analyses and style and sector rotation; expected beta; estimate revisions and earnings surprises; investor sentiment; and other factors. In selecting securities and other instruments, the portfolio managers employ quantitative screening and optimization tools to achieve desired market exposures while seeking to manage security-specific and other observable market risks. The portfolio is monitored on an ongoing basis and rebalanced as necessary to seek to ensure that desired market exposures and risk parameters are maintained. Securities may be sold if they exhibit performance that might counteract the desired exposures or to implement a revised allocation based on a modified top-down view. A security may also be sold if the sub-adviser believes it exhibits unusual volatility or price movement.

Under normal circumstances, the Fund currently expects to invest 0-75% of its net assets in equity securities, 25-90% in fixed-income securities and other fixed and floating-rate income instruments, 0-25% in commodities (primarily through the use of exchange-traded funds (“ETFs”) that invest in commodities or commodities-related investments) and/or currencies, and 0-25% in cash and cash equivalents. The Fund may also invest in derivatives (as described below) to obtain such exposures. To the extent the Fund holds cash as collateral for derivatives, or enters into forward foreign currency exchange contracts to hedge current portfolio holdings, the ranges described above may be exceeded. The expected long-term (over a true secular cycle of at least 10 years) target allocation of the Fund is 60% in fixed-income securities and 40% in equity securities. There is no requirement to manage the Fund within this target allocation. The Fund’s actual asset allocation may be materially different depending on market conditions, and the Fund’s asset allocation over shorter or longer market cycles may differ materially from the target.

The Fund may invest without limit in both developed and emerging markets, including frontier markets. Such investments may include securities denominated in foreign currencies and securities trading in the form of depositary receipts. The Fund may invest in fixed-income securities of any credit quality including securities rated below investment grade and comparable unrated securities (“junk”), and expects to invest principally in fixed-income securities that are issued by corporations, issued or guaranteed by the U.S. government or its agencies or instrumentalities, obligations of other sovereign nations, municipal obligations, mortgage-backed and asset-backed securities, inflation-linked debt securities or zero coupon bonds. The Fund may also invest in senior loans and variable rate obligations. The Fund may invest in stocks of companies of any capitalization, publicly traded real estate investment trusts (“REITs”) and exchange-traded notes (“ETNs”). The Fund may invest in ETFs, a type of pooled investment vehicle, in order to manage cash positions or seek exposure to certain markets or market sectors. The Fund currently expects to gain exposures to certain types of investments principally through ETFs. The Fund may invest in certain ETFs beyond the limits under the Investment Company Act of 1940, as amended (the “1940 Act”), subject to certain terms and conditions. Investment in cash or cash equivalents may include U.S. and foreign bank certificates of deposit, fixed time deposits, repurchase agreements, bankers’ acceptances and other short-term instruments with a remaining maturity of 397 days or less.

The Fund may engage in derivative transactions to seek return, to seek to hedge against fluctuations in securities prices, interest rates or currency exchange rates, to change the effective duration of the fixed-income securities in its portfolio, to manage certain investment risks and/or as a substitute for the purchase or sale of securities, currencies or commodities. The Fund expects to use derivatives principally when seeking to gain exposure to equity or fixed-income securities using futures contracts on securities indices and/or when seeking to gain or reduce exposure to certain currencies by buying or selling forward foreign currency exchange contracts, but may also purchase or sell forwards or other types of futures contracts; options on futures contracts; exchange-traded and over-the-counter options; equity collars, equity-linked securities and equity swap agreements; interest rate, total return, inflation and credit default swaps; forward rate agreements; and credit linked notes and other similarly structured products. The Fund may also engage in covered short sales (on individual securities held or on an index or basket of securities whose constituents are held in whole or in part or for which liquid assets have been segregated) and forward commitments. There is no stated limit on the Fund’s use of derivatives. The Fund may also lend its securities.

Principal Risks

Market Risk. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. These events may negatively impact broad segments of businesses and populations and may 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. Certain securities and other investments held by the Fund may experience increased volatility, illiquidity, or other potentially adverse effects in reaction to changing market conditions. Monetary and/or fiscal actions taken by U.S. or foreign governments to stimulate or stabilize the global economy may not be effective and could lead to high market volatility. No active trading market may exist for certain investments held by the Fund, which may impair the ability of the Fund to sell or to realize the current valuation of such investments in the event of the need to liquidate such assets.

Equity Securities Risk. The value of equity securities and related instruments may decline in response to adverse changes in the economy or the economic outlook; deterioration in investor sentiment; interest rate, currency, and commodity price fluctuations; adverse geopolitical, social or environmental developments; issuer and sector-specific considerations; unexpected trading activity among retail investors; or other factors. Market conditions may affect certain types of stocks to a greater extent than other types of stocks. If the stock market declines in value, the value of the Fund’s equity securities will also likely decline. Although prices can rebound, there is no assurance that values will return to previous levels.

Foreign Investment Risk. Foreign investments can be adversely affected by political, economic and market developments abroad, including the imposition of economic and other sanctions by the United States or another country. There may be less publicly available information about foreign issuers because they may not be subject to reporting practices, requirements or regulations comparable to those to which United States companies are subject. Foreign markets may be smaller, less liquid and more volatile than the major markets in the United States and, as a result, Fund share values may be more volatile. Trading in foreign markets typically involves higher expense than trading in the United States. The Fund may have difficulties enforcing its legal or contractual rights in a foreign country. Depositary receipts are subject to many of the risks associated with investing directly in foreign instruments.

Economic data as reported by sovereign entities may be delayed, inaccurate or fraudulent. In the event of a default by a sovereign entity, there are typically no assets to be seized or cash flows to be attached. Furthermore, the willingness or ability of a sovereign entity to restructure defaulted debt may be limited. Therefore, losses on sovereign defaults may far exceed the losses from the default of a similarly rated U.S. debt issuer.

Emerging Markets Investment Risk. Investment markets within emerging market countries are typically smaller, less liquid, less developed and more volatile than those in more developed markets like the United States, and may be focused in certain economic sectors. Emerging market securities often involve greater risks than developed market securities. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets. Such risks may be greater in frontier markets.

Currency Risk. Exchange rates for currencies fluctuate daily. The value of foreign investments may be affected favorably or unfavorably by changes in currency exchange rates in relation to the U.S. dollar. Currency markets generally are not as regulated as securities markets and currency transactions are subject to settlement, custodial and other operational risks.

ETF Risk. ETFs are subject to the risks of investing in the underlying securities or other investments. ETF shares may trade at a premium or discount to net asset value and are subject to secondary market trading risks. In addition, the Fund will bear a pro rata portion of the operating expenses of an ETF in which it invests. Other pooled investment vehicles generally are subject to risks similar to those of ETFs.

Sector Risk. Because the Fund may invest a significant portion of its assets in one or more sectors, the value of Fund shares may be affected by events that adversely affect such sector(s) and may fluctuate more than that of a fund that invests more broadly.

Credit Risk. Investments in fixed income securities or other income instruments (referred to below as “debt instruments”) are subject to the risk of non-payment of scheduled principal and interest. Changes in economic conditions or other circumstances may reduce the capacity of the party obligated to make principal and interest payments on such instruments and may lead to defaults. Such non-payments and defaults may reduce the value of Fund shares and income distributions. The value of debt instruments also may decline because of concerns about the issuer’s ability to make principal and interest payments. In addition, the credit ratings of debt instruments may be lowered if the financial condition

Eaton Vance Richard Bernstein Funds5Prospectus dated January 1, 2022

of the party obligated to make payments with respect to such instruments deteriorates. In the event of bankruptcy of the issuer of a debt instrument, the Fund could experience delays or limitations with respect to its ability to realize the benefits of any collateral securing the instrument. In order to enforce its rights in the event of a default, bankruptcy or similar situation, the Fund may be required to retain legal or similar counsel, which may increase the Fund’s operating expenses and adversely affect net asset value.

Interest Rate Risk. In general, the value of income securities will fluctuate based on changes in interest rates. The value of these securities is likely to increase when interest rates fall and decline when interest rates rise. Duration measures a fixed-income security’s price sensitivity to changes in the general level of interest rates. Generally, securities with longer durations or maturities are more sensitive to changes in interest rates than securities with shorter durations or maturities, causing them to be more volatile. Conversely, fixed-income securities with shorter durations or maturities will be less volatile but may provide lower returns than fixed-income securities with longer durations or maturities. In a rising interest rate environment, the duration of income securities that have the ability to be prepaid or called by the issuer may be extended. In a declining interest rate environment, the proceeds from prepaid or maturing instruments may have to be reinvested at a lower interest rate. Certain instruments held by the Fund may pay an interest rate based on the London Interbank Offered Rate (“LIBOR”), which is the average offered rate for various maturities of short-term loans between certain major international banks. LIBOR is used throughout global banking and financial industries to determine interest rates for a variety of financial instruments (such as debt instruments and derivatives) and borrowing arrangements. The ICE Benchmark Administration Limited, the administrator of LIBOR, is expected to cease publishing certain LIBOR settings on December 31, 2021, and the remaining LIBOR settings on June 30, 2023. Although the transition process away from LIBOR has become increasingly well defined in advance of the anticipated discontinuation, the impact on certain debt securities, derivatives and other financial instruments that utilize LIBOR remains uncertain. The phase-out of LIBOR may result in, among other things, increased volatility or illiquidity in markets for instruments based on LIBOR and changes in the value of such instruments.

Derivatives Risk. The Fund’s exposure to derivatives involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other investments. The use of derivatives can lead to losses because of adverse movements in the price or value of the security, instrument, index, currency, commodity, economic indicator or event underlying a derivative (“reference instrument”), due to failure of a counterparty or due to tax or regulatory constraints. Derivatives may create leverage in the Fund, which represents a non-cash exposure to the underlying reference instrument. Leverage can increase both the risk and return potential of the Fund. Derivatives risk may be more significant when derivatives are used to enhance return or as a substitute for a cash investment position, rather than solely to hedge the risk of a position held by the Fund. Use of derivatives involves the exercise of specialized skill and judgment, and a transaction may be unsuccessful in whole or in part because of market behavior or unexpected events. Changes in the value of a derivative (including one used for hedging) may not correlate perfectly with the underlying reference instrument. Derivative instruments traded in over-the-counter markets may be difficult to value, may be illiquid, and may be subject to wide swings in valuation caused by changes in the value of the underlying reference instrument. If a derivative’s counterparty is unable to honor its commitments, the value of Fund shares may decline and the Fund could experience delays in the return of collateral or other assets held by the counterparty. The loss on derivative transactions may substantially exceed the initial investment, particularly when there is no stated limit on the Fund’s use of derivatives. A derivative investment also involves the risks relating to the reference instrument underlying the investment.

When-Issued and Forward Commitment Risk. Securities purchased on a when-issued or forward commitment basis are subject to the risk that when delivered they will be worth less than the agreed upon payment price.

ETN Risk. ETNs are debt obligations and their payments of interest or principal are linked to the performance of a reference investment (typically an index). ETNs are subject to the performance of their issuer and may lose all or a portion of their entire value if the issuer fails or its credit rating changes. An ETN that is tied to a specific index may not be able to replicate and maintain exactly the composition and weighting of the components of that index. ETNs also incur certain expenses not incurred by the reference investment and the cost of owning an ETN may exceed the cost of investing directly in the reference investment. The market trading price of an ETN may be more volatile than the reference investment it is designed to track. The Fund may purchase an ETN at prices that exceed its net asset value and may sell such investments at prices below such net asset value. The Fund may not be able to liquidate ETN holdings at the time and price desired, which may impact Fund performance.

Smaller Company Risk. The stocks of smaller, less seasoned companies are generally subject to greater price fluctuations, limited liquidity, higher transaction costs and higher investment risk than the stocks of larger, more established companies. Such companies may have limited product lines, markets or financial resources, may be dependent on a limited management group, and may lack substantial capital reserves or an established performance record. There may be generally less publicly available information about such companies than for larger, more established

Eaton Vance Richard Bernstein Funds6Prospectus dated January 1, 2022

companies. Stocks of these companies frequently have lower trading volumes making them more volatile and potentially more difficult to value.

U.S. Government Securities Risk. Although certain U.S. Government-sponsored agencies (such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association) may be chartered or sponsored by acts of Congress, their securities are neither issued nor guaranteed by the U.S. Treasury. U.S. Treasury securities generally have a lower return than other obligations because of their higher credit quality and market liquidity.

Lower Rated Investments Risk. Investments rated below investment grade and comparable unrated investments (sometimes referred to as “junk”) have speculative characteristics because of the credit risk associated with their issuers. Changes in economic conditions or other circumstances typically have a greater effect on the ability of issuers of lower rated investments to make principal and interest payments than they do on issuers of higher rated investments. An economic downturn generally leads to a higher non-payment rate, and a lower rated investment may lose significant value before a default occurs. Lower rated investments typically are subject to greater price volatility and illiquidity than higher rated investments.

Municipal Obligations Risk. The amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser and sub-adviser than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and less liquid than many other securities markets, which may limit the Fund’s ability to sell its municipal obligations at attractive prices. The differences between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress. Less liquid obligations can become more difficult to value and be subject to erratic price movements. The increased presence of non-traditional participants (such as proprietary trading desks of investment banks and hedge funds) or the absence of traditional participants (such as individuals, insurance companies, banks and life insurance companies) in the municipal markets may lead to greater volatility in the markets because non-traditional participants may trade more frequently or in greater volume.

Real Estate Risk. Real estate investments are subject to risks associated with owning real estate, including declines in real estate values, increases in property taxes, fluctuations in interest rates, limited availability of mortgage financing, decreases in revenues from underlying real estate assets, declines in occupancy rates, changes in government regulations affecting zoning, land use, and rents, environmental liabilities, and risks related to the management skill and creditworthiness of the issuer. Companies in the real estate industry may also be subject to liabilities under environmental and hazardous waste laws, among others. REITs must satisfy specific requirements for favorable tax treatment and can involve unique risks in addition to the risks generally affecting the real estate industry. Changes in underlying real estate values may have an exaggerated effect to the extent that investments are concentrated in particular geographic regions or property types.

Commodity-Related Investments Risk. The value of commodity investments will generally be affected by overall market movements and factors specific to a particular industry or commodity, which may include weather, embargoes, tariffs, and health, political, international and regulatory developments. Economic and other events (whether real or perceived) can reduce the demand for commodities, which may reduce market prices and cause the value of the Fund’s commodity investments to fall. The frequency and magnitude of such changes are unpredictable. Exposure to commodities and commodity markets may subject the Fund to greater volatility than investments in traditional securities. No active trading market may exist for certain commodity investments, which may impair the ability of the Fund to sell or to realize the full value of such investments in the event of the need to liquidate such investments. In addition, adverse market conditions may impair the liquidity of actively traded commodity investments.

Liquidity Risk. The Fund is exposed to liquidity risk when trading volume, lack of a market maker or trading partner, large position size, market conditions, or legal restrictions impair its ability to sell particular investments or to sell them at advantageous market prices. Consequently, the Fund may have to accept a lower price to sell an investment or continue to hold it or keep the position open, sell other investments to raise cash or abandon an investment opportunity, any of which could have a negative effect on the Fund’s performance. These effects may be exacerbated during times of financial or political stress.

Additional Risks of Loans. Loans are traded in a private, unregulated inter-dealer or inter-bank resale market and are generally subject to contractual restrictions that must be satisfied before a loan can be bought or sold. These restrictions may impede the Fund’s ability to buy or sell loans (thus affecting their liquidity) and may negatively impact the transaction price. See also “Market Risk” above. It also may take longer than seven days for transactions in loans to settle. Due to the possibility of an extended loan settlement process, the Fund may hold cash, sell investments or temporarily borrow from banks or other lenders to meet short-term liquidity needs, such as to satisfy redemption requests from Fund shareholders. The types of covenants included in loan agreements generally vary depending on market conditions, the creditworthiness

Eaton Vance Richard Bernstein Funds7Prospectus dated January 1, 2022

of the issuer, the nature of the collateral securing the loan and possibly other factors. Loans with fewer covenants that restrict activities of the borrower may provide the borrower with more flexibility to take actions that may be detrimental to the loan holders and provide fewer investor protections in the event of such actions or if covenants are breached. The Fund may experience relatively greater realized or unrealized losses or delays and expense in enforcing its rights with respect to loans with fewer restrictive covenants. Loans to entities located outside of the U.S. (including loans to sovereign entities) may have substantially different lender protections and covenants as compared to loans to U.S. entities and may involve greater risks. The Fund may have difficulties and incur expense enforcing its rights with respect to non-U.S. loans and such loans could be subject to bankruptcy laws that are materially different than in the U.S. Sovereign entities may be unable or unwilling to meet their obligations under a loan due to budgetary limitations or economic or political changes within the country. Loans may be structured such that they are not securities under securities law, and in the event of fraud or misrepresentation by a borrower, lenders may not have the protection of the anti-fraud provisions of the federal securities laws. Loans are also subject to risks associated with other types of income investments, including credit risk and risks of lower rated investments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. Movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain types of mortgage- and asset-backed securities. Although certain mortgage- and asset-backed securities are guaranteed as to timely payment of interest and principal by a government entity, the market price for such securities is not guaranteed and will fluctuate. The purchase of mortgage- and asset-backed securities issued by non-government entities may entail greater risk than such securities that are issued or guaranteed by a government entity. Mortgage- and asset-backed securities issued by non-government entities may offer higher yields than those issued by government entities, but may also be subject to greater volatility than government issues and can also be subject to greater credit risk and the risk of default on the underlying mortgages or other assets. Investments in mortgage- and asset-backed securities are subject to both extension risk, where borrowers pay off their debt obligations more slowly in times of rising interest rates, and prepayment risk, where borrowers pay off their debt obligations sooner than expected in times of declining interest rates.

Leverage Risk. Certain Fund transactions may give rise to leverage. Leverage can result from a non-cash exposure to an underlying reference instrument. Leverage can increase both the risk and return potential of the Fund. The Fund is required to segregate liquid assets or otherwise cover the Fund’s obligation created by a transaction that may give rise to leverage. The use of leverage may cause the Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet segregation requirements. Leverage may cause the Fund’s share price to be more volatile than if it had not been leveraged, as certain types of leverage may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. The loss on leveraged investments may substantially exceed the initial investment.

Zero-Coupon Bond Risk. Zero-coupon bonds may experience greater volatility in market value due to changes in interest rates. The Fund accrues income on the discount amortization of these investments, which it is required to distribute each year. The Fund may be required to sell investments to obtain cash needed for income distributions.

Short Sale Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to replace the borrowed security. Short sale risks include, among others, the potential loss of more money than the actual cost of the investment, and the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

Risks Associated with Active and Quantitative Management. The success of the Fund’s investment strategy depends on portfolio management’s successful application of analytical skills and investment judgment. Active management involves subjective decisions. The portfolio managers also use quantitative investment techniques and analyses in making investment decisions for the Fund. There can be no assurance that these techniques will achieve the desired results.

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral if the borrower fails financially. The Fund could also lose money if the value of the collateral decreases.

Eaton Vance Richard Bernstein Funds8Prospectus dated January 1, 2022

have an adverse impact on the remaining shareholders in the Fund. The Fund relies on various service providers, including the investment adviser, in its operations and is susceptible to operational, information security and related events (such as public health crises, cyber or hacking attacks) that may affect the service providers or the services that they provide to the Fund. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and how the Fund’s average annual returns over time compare with those of two broad-based securities market indices and with a blended index. The returns in the bar chart are for Class A shares and do not reflect a sales charge. If the sales charge was reflected, the returns would be lower. Past performance (both before and after taxes) is not necessarily an indication of how the Fund will perform in the future. The Fund’s performance for certain periods reflects the effects of expense reductions. Absent these reductions, performance for certain periods would have been lower. Updated Fund performance information can be obtained by visiting www.eatonvance.com.

After-tax returns are calculated using the highest historical individual federal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on a shareholder’s tax situation and the actual characterization of distributions, and may differ from those shown. After-tax returns are not relevant to shareholders who hold shares in tax-deferred accounts or to shares held by non-taxable entities. After-tax returns for other Classes of shares will vary from the after-tax returns presented for Class A shares. Return After Taxes on Distributions for a period may be the same as Return Before Taxes for that period because no taxable distributions were made during that period. Also, Return After Taxes on Distributions and Sale of Fund Shares for a period may be greater than or equal to Return Before Taxes and/or Return After Taxes on Distributions for the same period because of losses realized on the sale of Fund shares.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities and derivative instruments that provide exposure to equity securities (the “80% Policy”). The Fund may invest up to 20% of its net assets in fixed-income securities, including securities rated below investment grade and comparable unrated securities (“junk”); other fixed and floating-rate income instruments; and/or in currencies. The Fund may invest an unlimited amount of its assets in foreign securities issued by companies domiciled in developed or emerging market countries including frontier markets. Such investments may include securities denominated in foreign currencies and securities trading in the form of depositary receipts. The Fund may invest in stocks of companies of any capitalization, publicly traded real estate investment trusts (“REITs”) and exchange-traded notes (“ETNs”). The Fund may invest in exchange-traded funds (“ETFs”), a type of pooled investment vehicle, in order to manage cash positions or seek exposure to certain markets or market sectors. The Fund may invest in certain ETFs beyond the limits under the Investment Company Act of 1940, as amended (the “1940 Act”), subject to certain terms and conditions.

The Fund may engage in derivative transactions to seek return, to seek to hedge against fluctuations in securities prices, interest rates or currency exchange rates, or as a substitute for the purchase or sale of securities or currencies. The Fund expects to use derivatives principally when seeking to gain exposure to equity securities using futures contracts on securities indices and/or when seeking to gain or reduce exposure to certain currencies by buying or selling forward foreign currency exchange contracts. However, the Fund may also purchase or sell forwards or other types of futures contracts; options on futures contracts; exchange-traded and over-the-counter options; equity collars; equity-linked securities; equity swap agreements and other derivatives as described in the prospectus. The Fund may also engage in covered short sales (on individual securities held or on an index or basket of securities whose constituents are held in whole or in part or for which liquid assets have been segregated) and forward commitments. There is no stated limit on the Fund’s use of derivatives. The Fund may also lend its securities.

The Fund is managed in a macro-driven, top-down style that emphasizes and de-emphasizes various global equity market segments at different times. Market segments chosen for emphasis and/or de-emphasis may vary from general market consensus views and the Fund may at times seek to identify areas where, in the sub-adviser’s opinion, there is scarcity of capital and/or potentially overlooked investment opportunities. In using this “beta” management style, leading exposures will vary among growth and value; small, mid and large cap; U.S. and non-U.S., and developed and emerging markets, based on the sub-adviser’s assessment of a range of proprietary and non-proprietary quantitative indicators and the firm’s macro-economic analysis and judgment. It is expected that the macro-economic factors and indicators will evolve over time and may include the following: global equity market valuations; global yield curves; asset class, regional, and country correlations; profit cycle analyses and style and sector rotation; expected beta; estimate revisions and earnings surprises; investor sentiment and other factors. In selecting securities and other instruments, the portfolio managers employ quantitative screening and optimization tools to achieve desired market exposures while seeking to manage stock-specific and other observable market risks. The portfolio is monitored on an ongoing basis and rebalanced as necessary to seek to ensure that desired market exposures and risk parameters are maintained. Stocks may be sold if they exhibit performance that might counteract the desired exposures or to implement a revised allocation based on a modified top-down view. A security may also be sold if the sub-adviser believes it exhibits unusual volatility or price movement.

The Fund will exercise a flexible strategy and is not limited by investment style or by an issuer’s location, size, market capitalization or industry sector. The strategy may have none, some or all of its assets invested in a particular market segment at a given time, and across market segments in relative proportions that change over time. At any time, up to 100% of the Fund’s assets may be invested in either U.S. or foreign securities, including issuers domiciled in emerging market countries.

Principal Risks

Eaton Vance Richard Bernstein Funds12Prospectus dated January 1, 2022

Sector Risk. Because the Fund may, under certain market conditions, invest a significant portion of its assets in one or more sectors, the value of Fund shares may be affected by events that adversely affect such sector(s) and may fluctuate more than that of a fund that invests more broadly.

Credit Risk. Investments in fixed income and other debt obligations, including loans, (referred to below as “debt instruments”) are subject to the risk of non-payment of scheduled principal and interest. Changes in economic conditions or other circumstances may reduce the capacity of the party obligated to make principal and interest payments on such instruments and may lead to defaults. Such non-payments and defaults may reduce the value of Fund shares and income distributions. The value of debt instruments also may decline because of concerns about the issuer’s ability to make principal and interest payments. In addition, the credit ratings of debt instruments may be lowered if the financial condition of the party obligated to make payments with respect to such instruments deteriorates. In the event of bankruptcy of the issuer of a debt instrument, the Fund could experience delays or limitations with respect to its ability to realize the benefits of any collateral securing the instrument. In order to enforce its rights in the event of a default, bankruptcy or similar situation, the Fund may be required to retain legal or similar counsel, which may increase the Fund’s operating expenses and adversely affect net asset value.

Eaton Vance Richard Bernstein Funds13Prospectus dated January 1, 2022

securities with longer durations or maturities. In a rising interest rate environment, the duration of income securities that have the ability to be prepaid or called by the issuer may be extended. In a declining interest rate environment, the proceeds from prepaid or maturing instruments may have to be reinvested at a lower interest rate. Certain instruments held by the Fund may pay an interest rate based on the London Interbank Offered Rate (“LIBOR”), which is the average offered rate for various maturities of short-term loans between certain major international banks. LIBOR is used throughout global banking and financial industries to determine interest rates for a variety of financial instruments (such as debt instruments and derivatives) and borrowing arrangements. The ICE Benchmark Administration Limited, the administrator of LIBOR, is expected to cease publishing certain LIBOR settings on December 31, 2021, and the remaining LIBOR settings on June 30, 2023. Although the transition process away from LIBOR has become increasingly well defined in advance of the anticipated discontinuation, the impact on certain debt securities, derivatives and other financial instruments that utilize LIBOR remains uncertain. The phase-out of LIBOR may result in, among other things, increased volatility or illiquidity in markets for instruments based on LIBOR and changes in the value of such instruments.

Eaton Vance Richard Bernstein Funds14Prospectus dated January 1, 2022

General Fund Investing Risks. The Fund is not a complete investment program and there is no guarantee that the Fund will achieve its investment objective. It is possible to lose money by investing in the Fund. The Fund is designed to be a long-term investment vehicle and is not suited for short-term trading. Investors in the Fund should have a long-term investment perspective and be able to tolerate potentially sharp declines in value. Purchase and redemption activities by Fund shareholders may impact the management of the Fund and its ability to achieve its investment objective(s). In addition, the redemption by one or more large shareholders or groups of shareholders of their holdings in the Fund could have an adverse impact on the remaining shareholders in the Fund. The Fund relies on various service providers, including the investment adviser, in its operations and is susceptible to operational, information security and related events (such as public health crises, cyber or hacking attacks) that may affect the service providers or the services that they provide to the Fund. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Important Information Regarding Fund Shares

Purchase and Sale of Fund Shares

You may purchase, redeem or exchange Fund shares on any business day, which is any day the New York Stock Exchange is open for business. You may purchase, redeem or exchange Fund shares either through your financial intermediary or (except for purchases of Class C shares by accounts with no specified financial intermediary) directly from a Fund either by writing to the Fund, P.O. Box 9653, Providence, RI 02940-9653, or by calling 1-800-262-1122. The minimum initial purchase or exchange into a Fund is $1,000 for each Class (with the exception of Class I) and $250,000 for Class I (waived in certain circumstances). There is no minimum for subsequent investments.

Tax Information

If your shares are held in a taxable account, each Fund’s distributions will be taxed to you as ordinary income and/or capital gains, unless you are exempt from taxation. If your shares are held in a tax-advantaged account, you will generally be taxed only upon withdrawals from the account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase a Fund’s shares through a broker-dealer or other financial intermediary (such as a bank) (collectively, “financial intermediaries”), the Fund, its principal underwriter and its affiliates may pay the financial intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the financial intermediary and your salesperson to recommend a Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

Investment Objectives & Principal Policies and Risks

The investment objective and principal investment policies and risks of each Fund are described in its Fund Summary. Set forth below is additional information about such policies and risks, as well as information about other types of investments and practices in which each Fund may engage from time to time, unless otherwise noted. References to the Fund below are to each Fund. See also “Strategies and Risks” in the Statement of Additional Information (“SAI”).

Definitions. As used herein, the following terms have the indicated meaning: “1940 Act” means the Investment Company Act of 1940, as amended; “1933 Act” means the Securities Act of 1933, as amended; “Code” means the Internal Revenue Code of 1986, as amended; “ERISA” means the Employee Retirement Income Security Act of 1974, as amended; and “investment adviser” means the Fund’s investment adviser but if the Fund is sub-advised, it refers to the sub-adviser(s) providing day-to-day management with respect to the investments or strategies discussed.

Equity Securities. Equity securities include: common stocks; preferred stocks, including convertible and contingent convertible preferred stocks; equity interests in trusts, partnerships, joint ventures and other unincorporated entities or enterprises; depositary receipts, rights and warrants in underlying equity interests; and other securities that are treated as equity for U.S. federal income tax purposes. The Fund cannot predict the income it might receive from equity securities because issuers generally have discretion as to the payment of any dividends or distributions.

The value of equity securities and related instruments may decline in response to adverse changes in the economy or the economic outlook; deterioration in investor sentiment; interest rate, currency, and commodity price fluctuations; adverse geopolitical, social or environmental developments; issuer- and sector-specific considerations; unexpected trading activity among retail investors; and other factors. Market conditions may affect certain types of stocks to a greater extent than other types of stocks. If the stock market declines, the value of Fund shares will also likely decline. Although stock prices can rebound, there is no assurance that values will return to previous levels.

Foreign Investments. Investments in foreign issuers could be affected by factors not present in the United States, including expropriation, armed conflict, confiscatory taxation, lack of uniform accounting and auditing standards, less publicly available financial and other information, and potential difficulties in enforcing contractual obligations. Because foreign issuers may not be subject to uniform accounting, auditing and financial reporting standard practices and requirements and regulatory measures comparable to those in the United States, there may be less publicly available information about such foreign issuers. Settlements of securities transactions in foreign countries are subject to risk of loss, may be delayed and are generally less frequent than in the United States, which could affect the liquidity of the Fund’s assets. Evidence of ownership of certain foreign investments may be held outside the United States, and the Fund may be subject to the risks associated with the holding of such property overseas. Trading in certain foreign markets is also subject to liquidity risk.

Foreign investment in the securities markets of certain foreign countries is restricted or controlled to varying degrees. Foreign issuers may become subject to sanctions imposed by the United States or another country, which could result in the immediate freeze of the foreign issuers’ assets or securities. The imposition of such sanctions could impair the market value of the securities of such foreign issuers and limit the Fund’s ability to buy, sell, receive or deliver the securities. In addition, as a result of economic sanctions, the Fund may be forced to sell or otherwise dispose of investments at inopportune times or prices, which could result in losses to the Fund and increased transaction costs. If a deterioration occurs in a country's balance of payments, the country could impose temporary restrictions on foreign capital remittances. The Fund could also be adversely affected by delays in, or a refusal to grant, any required governmental approval for repatriation, as well as by other restrictions on investment. The risks posed by such actions with respect to a particular foreign country, its nationals or industries or businesses within the country may be heightened to the extent the Fund invests significantly in the affected country or region or in issuers from the affected country that depend on global markets.

Political events in foreign countries may cause market disruptions. In June 2016, the United Kingdom (“UK”) voted in a referendum to leave the European Union (“EU”) (“Brexit”). Effective January 31, 2020, the UK ceased to be a member of the EU and, following a transition period during which the EU and the UK Government engaged in a series of negotiations regarding the terms of the UK’s future relationship with the EU, the EU and the UK Government signed an agreement on December 30, 2020 regarding the economic relationship between the UK and the EU. This agreement became effective on a provisional basis on January 1, 2021 and entered into full force on May 1, 2021. There remains significant market uncertainty regarding Brexit’s ramifications, and the range and potential implications of the possible political, regulatory, economic, and market outcomes in the UK, EU and beyond are difficult to predict. The end of the Brexit transition period may cause greater market volatility and illiquidity, currency fluctuations, deterioration in economic activity, a decrease in business confidence, and an increased likelihood of a recession in the UK. If one or more additional countries leave the EU or the EU dissolves, the world’s securities markets likely will be significantly disrupted.

Eaton Vance Richard Bernstein Funds17Prospectus dated January 1, 2022

As an alternative to holding foreign-traded investments, the Fund may invest in U.S. dollar-denominated investments of foreign companies that trade on U.S. exchanges or in the U.S. over-the-counter market including depositary receipts, such as American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”), which evidence ownership of shares of a foreign issuer and are alternatives to directly purchasing the underlying foreign securities in their national markets and currencies. However, they continue to be subject to many of the risks associated with investing directly in foreign securities. These risks include the political and economic risks of the underlying issuer’s country, as well as in the case of depositary receipts traded on foreign markets, currency risk. Depositary receipts may be sponsored or unsponsored. Unsponsored depositary receipts are established without the participation of the issuer. As a result, available information concerning the issuer of an unsponsored depository receipt may not be as current as for sponsored depositary receipts, and the prices of unsponsored depositary receipts may be more volatile than if such instruments were sponsored by the issuer. Unsponsored depositary receipts may involve higher expenses, may not pass through voting or other shareholder rights and may be less liquid.

The Fund may invest in securities and other instruments (including loans) issued, guaranteed, or backed by sovereign or government entities. Economic data as reported by sovereign or government entities and other issuers may be delayed, inaccurate or fraudulent. Many sovereign or government debt obligations may be rated below investment grade. Any restructuring of a sovereign or government debt obligation held by the Fund will likely have a significant adverse effect on the value of the obligation. In the event of default of a sovereign or government debt, the Fund may be unable to pursue legal action against the issuer or secure collateral on the debt, as there are typically no assets to be seized or cash flows to be attached. Furthermore, the willingness or ability of a sovereign or government entity to restructure defaulted debt may be limited. Therefore, losses on sovereign or government defaults may far exceed the losses from the default of a similarly rated U.S. corporate debt issuer.

Emerging Markets Investments. The risks of foreign investments can be more significant in emerging markets, which include frontier markets. Emerging markets may offer higher potential for gains and losses than investments in the developed markets of the world. Political and economic structures in emerging market countries generally lack the social, political and economic stability of developed countries, which may affect the value of the Fund’s investments in these countries and also the ability of the Fund to access markets in such countries. Securities markets within emerging market countries may experience low or non-existent trading volume, resulting in a lack of liquidity and increased volatility in prices for such securities, as compared to securities of comparable issuers in more developed capital markets. Governmental actions can have a significant effect on the economic conditions in emerging market countries, which also may adversely affect the value and liquidity of the Fund’s investments. In particular, trade disputes may result in governmental actions that could have an adverse effect on investments in emerging market countries, including but not limited to restrictions on investments in, or required divestment of, particular issuers or industries. Such actions may effectively restrict or eliminate the Fund's ability to purchase or sell investments in emerging market countries, and thus may make them less liquid or more difficult to value, or may force the Fund to sell or otherwise dispose of such investments at inopportune times or prices. There may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed capital markets, and such issuers may not be subject to accounting, auditing and financial reporting standards and requirements comparable to those to which U.S. companies are subject . The laws of emerging market countries relating to the limited liability of corporate shareholders, fiduciary duties of officers and directors, and bankruptcy of state enterprises are generally less developed than or different from such laws in the United States. It may be more difficult to make a claim or obtain a judgment in the courts of these countries than it is in the United States. In addition, due to jurisdictional limitations, U.S. authorities (e.g., SEC and the U.S. Department of Justice) may be limited in their ability to enforce regulatory or legal obligations in emerging market countries. The possibility of fraud, negligence, undue influence being exerted by an issuer or refusal to recognize ownership exists in some emerging markets. The prices at which investments may be acquired may be affected by trading by persons with information that is not publicly available and by securities transactions by brokers in anticipation of transactions in particular securities. Disruptions due to work stoppages and trading improprieties in foreign securities markets have caused such markets to close. If extended closings were to occur in stock markets where the Fund is heavily invested, the Fund’s ability to redeem Fund shares could become impaired. In such circumstances, the Fund may have to sell more liquid securities than it would otherwise choose to sell. Emerging market securities are also subject to speculative trading, which contributes to their volatility. These foregoing risks may be even greater in frontier markets.

Eaton Vance Richard Bernstein Funds18Prospectus dated January 1, 2022

dollars. If the U.S. dollar decreases in value relative to a foreign currency, a security denominated in that foreign currency will be worth more in U.S. dollars. A devaluation of a currency by a country’s government or banking authority will have a significant impact on the value of any investments denominated in that currency. Costs are incurred in connection with conversions between currencies.

The Fund may engage in spot transactions and forward foreign currency exchange contracts, purchase and sell options on currencies and purchase and sell currency futures contracts and related options thereon (collectively, “Currency Instruments”) to seek to hedge against the decline in the value of currencies in which its portfolio holdings are denominated against the U.S. dollar or to seek to enhance returns.

Eurodollar and Yankee Dollar Instruments. The Fund may invest a portion of its assets in Eurodollar and Yankee Dollar instruments. Eurodollar instruments are bonds that pay interest and principal in U.S. dollars held in banks outside the United States, primarily in Europe. Eurodollar instruments are usually issued on behalf of multinational companies and foreign governments by large underwriting groups composed of banks and issuing houses from many countries. Yankee Dollar instruments are U.S. dollar denominated bonds issued in the United States by foreign banks and corporations.

These investments involve risks that are different from investments in securities issued by U.S. issuers, and may carry many of the same risks as investing in foreign investments, as well as additional risks, including adverse political and economic developments, the possible imposition of withholding taxes on interest income payable on such obligations, the possible seizure or nationalization of foreign deposits and the possible establishment of exchange controls or other foreign governmental laws or restrictions that might adversely affect the repayment of principal and the payment of interest.

Fixed-Income Securities and Other Debt Instruments. Fixed-income securities and other debt instruments include all types of fixed and floating-rate bonds and notes, such as convertible securities and other hybrid securities (other than preferred stock); corporate commercial paper; mortgage-backed and other asset-backed securities; inflation-indexed bonds issued by both governments and corporations; structured notes, including “indexed” securities; loans; loan participations and assignments; delayed funding loans and revolving credit facilities; and bank certificates of deposit, fixed time deposits, bank deposits (or investments structured to provide the same type of exposure) and bankers’ acceptances of foreign and domestic banks and other debt instruments. Fixed-income securities and other debt instruments are issued by: foreign governments or their subdivisions, agencies and government-sponsored enterprises; sovereign entities; international agencies or supranational entities; the U.S. Government, its agencies or government-sponsored enterprises (or guaranteed thereby); central or quasi-sovereign banks and U.S. and foreign corporations. Fixed-income securities and other debt instruments include deep discount bonds, such as zero coupon bonds, deferred interest bonds, bonds or securities on which the interest is payable in-kind (“PIK securities”), which are debt obligations that are issued at a significant discount from face value, and securities purchased on a forward commitment or when-issued basis. While zero coupon bonds do not make periodic payments of interest, deferred interest bonds provide for a period of delay before the regular payment of interest begins. PIK securities provide that the issuer thereof may, at its option, pay interest in cash or in the form of additional securities.

Commodities-Related Investments. Commodity-related investments include, but are not limited to, commodities contracts, commodity futures or options thereon (investments in contracts for the future purchase or sale of commodities); commodity exchange-traded funds (exchange-traded funds that track the price of a single commodity, such as gold or oil, or a basket of commodities); commodity exchange traded notes (non-interest paying debt instruments whose price fluctuates (by contractual commitment) with an underlying commodities index); total return swaps based on a commodity index (permitting one party to receive/pay the total return on a commodity index against payment/receipt of an agreed upon spread/interest rate); commodity-linked notes (providing a return based on a formula referenced to a commodity index); sovereign issued oil warrants (a sovereign obligation the coupon on which is contingent on the price of oil); precious metals; and any other commodities-related investment permitted by law. Commodities-related investments may be used to gain exposure to a particular type of commodity, basket of commodities, commodity market or commodity index, or to hedge such exposures or a position in a commodity producing country.

The risks associated with investing in commodities include regulatory, health, economic and political developments, weather events and natural disasters, pestilence, market disruptions and the fact that commodity prices may have greater volatility than investments in traditional securities. The prices of energy, industrial metals, precious metals, agriculture, and livestock sector commodities may fluctuate widely due to factors such as changes in value, supply and demand and governmental regulatory policies. The metals sector can be affected by sharp price volatility over short periods caused by global economic, financial and political factors, resource availability, government regulation, economic cycles, changes in inflation or expectations about inflation, interest rates, currency fluctuations, metal sales by governments, central banks or international agencies, investment speculation and fluctuation in supply and demand. Commodity-related investments are often offered by companies in the financial services sector, including the banking, brokerage, and insurance sectors. As a

Eaton Vance Richard Bernstein Funds19Prospectus dated January 1, 2022

result, events affecting issuers in the financial services sector may cause the Fund’s share value to fluctuate. Although investments in commodities typically move in different directions than traditional equity and fixed-income securities, when the value of those traditional securities is declining due to adverse economic conditions, there is no guarantee that these investments will perform differently, and at certain times the price movements of commodity-related investments have been parallel to those of equity and fixed-income securities.

Derivatives. Generally, derivatives can be characterized as financial instruments whose performance is derived at least in part from the performance of an underlying reference instrument. Derivative instruments may be acquired in the United States or abroad consistent with the Fund’s investment strategy and may include the various types of exchange-traded and over-the-counter (“OTC”) instruments described herein and other instruments with substantially similar characteristics and risks. Fund obligations created pursuant to derivative instruments may give rise to leverage, which would subject the Fund to the requirements described under “Asset Coverage” in the Fund’s SAI. The Fund may invest in a derivative transaction if it is permitted to own, invest in, or otherwise have economic exposure to the reference instrument. Depending on the type of derivative instrument and the Fund’s investment strategy, a reference instrument could be a security, instrument, index, currency, commodity, economic indicator or event (“reference instruments”). The Fund may engage in derivative transactions to seek return, to hedge against fluctuations in securities prices, interest rates or currency exchange rates, to change the effective duration of the fixed-income securities in its portfolio, to manage certain investment risks and/or as a substitute for the purchase or sale of securities, currencies or commodities. The Fund may trade in the specific type(s) and/or combinations of derivative transactions listed below.

Derivative instruments are subject to a number of risks, including adverse or unexpected movements in the price of the reference instrument, and counterparty, liquidity, market, tax and leverage risks. Certain derivatives may also be subject to credit risk and interest rate risk. In addition, derivatives also involve the risk that changes in their value may not correlate perfectly with the assets, rates, indices or instruments they are designed to hedge or closely track. Use of derivative instruments may cause the realization of higher amounts of short-term capital gains (generally taxed at ordinary income tax rates) than if such instruments had not been used. Success in using derivative instruments to hedge portfolio assets depends on the degree of price correlation between the derivative instruments and the hedged asset. Imperfect correlation may be caused by several factors, including temporary price disparities among the trading markets for the derivative instrument, the reference instrument and the Fund’s assets. To the extent that a derivative instrument is intended to hedge against an event that does not occur, the Fund may realize losses.

OTC derivative instruments involve an additional risk in that the issuer or counterparty may fail to perform its contractual obligations. Some derivative instruments are not readily marketable or may become illiquid under adverse market conditions. In addition, during periods of market volatility, an option or commodity exchange or swap execution facility or clearinghouse may suspend or limit trading in an exchange-traded derivative instrument, which may make the contract temporarily illiquid and difficult to price. Commodity exchanges may also establish daily limits on the amount that the price of a futures contract or futures option can vary from the previous day’s settlement price. Once the daily limit is reached, no trades may be made that day at a price beyond the limit. This may prevent the closing out of positions to limit losses. The ability to terminate OTC derivative instruments may depend on the cooperation of the counterparties to such contracts. For thinly traded derivative instruments, the only source of price quotations may be the selling dealer or counterparty. In addition, certain provisions of the Code limit the use of derivative instruments. Derivatives permit the Fund to increase or decrease the level of risk, or change the character of the risk, to which its portfolio is exposed in much the same way as the Fund can increase or decrease the level of risk, or change the character of the risk, of its portfolio by making investments in specific securities. There can be no assurance that the use of derivative instruments will benefit the Fund.

The U.S. and non-U.S. derivatives markets have undergone substantial changes in recent years as a result of changes under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) in the United States and regulatory changes in Europe, Asia and other non-U.S. jurisdictions. In particular, the Dodd-Frank Act and related regulations require many derivatives to be cleared and traded on an exchange, expand entity registration requirements, impose business conduct requirements on counterparties, and impose other regulatory requirements that will continue to change derivatives markets as regulations are implemented. As of October 28, 2020, the SEC has adopted new regulations that may significantly alter a Fund’s regulatory obligations with regard to its derivatives usage. In particular, the new regulations will, upon implementation, eliminate the current asset segregation framework for covering derivatives and certain other financial instruments, impose new responsibilities on the Board and establish new reporting and recordkeeping requirements for a Fund and may, depending on the extent to which a Fund uses derivatives, impose value at risk limitations on a Fund’s use of derivatives, and require the Fund’s Board to adopt a derivative risk management program. The implementation of these requirements may limit the ability of a Fund to use derivative instruments as part of its investment strategy, increase the costs of using these instruments or make them less effective. Additional future regulation of the derivatives markets may make the use of derivatives more costly, may limit the availability or reduce the liquidity of derivatives, and may impose limits or restrictions on the counterparties with which the Fund engages in derivative transactions. Fund management cannot predict the effects of any new governmental regulation that may be

Eaton Vance Richard Bernstein Funds20Prospectus dated January 1, 2022

implemented, and there can be no assurance that any new government regulation will not adversely affect the Fund’s performance or ability to achieve its investment objectives.

Options. Options may be traded on an exchange and OTC. By buying a put option on a particular instrument, the Fund acquires a right to sell the underlying instrument at the exercise price. By buying a put option on an index, the Fund acquires a right to receive the cash difference between the strike price of the option and the index price at expiration. A purchased put position also typically can be sold at any time by selling at prevailing market prices. Purchased put options generally are expected to limit the Fund's risk of loss through a decline in the market value of the underlying security or index until the put option expires. When buying a put option, the Fund pays a premium to the seller of the option. If the price of the underlying security or index is above the exercise price of the option as of the option valuation date, the option expires worthless and the Fund will not be able to recover the option premium paid to the seller. The Fund may purchase uncovered put options on securities, meaning it will not own the securities underlying the option.

The Fund may also write (i.e., sell) put options. The Fund will receive a premium for selling a put option, which may increase the Fund's return. In selling a put option on a security, the Fund has the obligation to buy the security at an agreed upon price if the price of such instrument decreases below the exercise price. By selling a put option on an index, the Fund has an obligation to make a payment to the buyer to the extent that the value of the index decreases below the exercise price as of the option valuation date. If the value of the underlying security or index on the option’s expiration date is above the exercise price, the option will generally expire worthless and the Fund, as option seller, will have no obligation to the option holder.

The Fund may purchase call options. By purchasing a call option on a security, the Fund has the right to buy the security at the option’s exercise price. By buying a call option on an index, the Fund acquires the right to receive the cash difference between the market price of the index and strike price at expiration. Call options typically can be exercised any time prior to option maturity or, sold at the prevailing market price.

The Fund may also write (i.e., sell) a call option on a security or index in return for a premium. A call written on a security obligates the Fund to deliver the underlying security at the option exercise price. Written index call options obligate the Fund to make a cash payment to the buyer at expiration if the market price of the index is above the option strike price. Calls typically can also be bought back by the Fund at prevailing market prices and the Fund also may enter into closing purchase transactions with respect to written call options. The Fund may write call options on securities that it owns (so-called covered calls) and also may write uncovered call options. With respect to written covered calls, the Fund may sell the underlying security prior to entering into a closing purchase transaction on up to 5% of its net assets within three days of such transaction. The Fund may also engage in various types of option strategies using put and/or call options.

The Fund’s options positions are marked to market daily. The value of options is affected by changes in the value and dividend rates of their underlying instruments, changes in interest rates, changes in the actual or perceived volatility of the relevant index or market and the remaining time to the options’ expiration, as well as trading conditions in the options market. The hours of trading for options may not conform to the hours during which the underlying instruments are traded. To the extent that the options markets close before markets for the underlying instruments, significant price and rate movements can take place in the markets that would not be reflected concurrently in the options markets.

The Fund's ability to sell the instrument underlying a call option may be limited while the option is in effect unless the Fund enters into a closing purchase transaction. Uncovered call options have speculative characteristics and are riskier than covered call options because there is no underlying instrument held by the Fund that can act as a partial hedge. As the seller of a covered call option or an index call option, the Fund may forego, during the option’s life, the opportunity to profit from increases in the market value of the underlying instrument covering the call option above the sum of the premium received by the Fund and the exercise price of the call. The Fund also retains the risk of loss, minus the option premium received, should the price of the underlying instrument decline.

Participants in OTC markets are typically not subject to the same credit evaluation and regulatory oversight as are members of “exchange-based” markets. OTC option contracts generally carry greater liquidity risk than exchange-traded contracts. This risk may be increased in times of financial stress, if the trading market for OTC options becomes restricted. The ability of the Fund to transact business with any one or a number of counterparties may increase the potential for losses to the Fund, due to the lack of any independent evaluation of the counterparties or their financial capabilities, and the absence of a regulated market to facilitate settlement of the options.

Eaton Vance Richard Bernstein Funds21Prospectus dated January 1, 2022

a specific index at the close of the last trading day of the contract and the price at which the agreement is made. No physical delivery of the underlying securities in the index is made. It is the practice of holders of futures contracts to close out their positions on or before the expiration date by use of offsetting contract positions, and physical delivery of financial instruments or delivery of cash, as applicable, is thereby avoided. An option on a futures contract gives the holder the right to enter into a specified futures contract.

Forward Foreign Currency Exchange Contracts. A forward foreign currency exchange contract (“currency forward”) involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. These contracts may be bought or sold to protect against an adverse change in the relationship between currencies or to increase exposure to a particular foreign currency.

Certain currency forwards may be individually negotiated and privately traded, exposing them to credit and counterparty risks. The precise matching of the currency forward amounts and the value of the instruments denominated in the corresponding currencies will not generally be possible because the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the date on which the contract is entered into and the date it matures. There is additional risk that the use of currency forwards may reduce or preclude the opportunity for gain if the value of the currency should move in the direction opposite to the position taken and that currency forwards may create exposure to currencies in which the Fund’s securities are not denominated. In addition, it may not be possible to hedge against long-term currency changes. Currency forwards are subject to the risk of political and economic factors applicable to the countries issuing the underlying currencies. Furthermore, unlike trading in most other types of instruments, there is no systematic reporting of last sale information with respect to the foreign currencies underlying currency forwards. As a result, available information may not be complete.

Forward Rate Agreements. Under a forward rate agreement, the Fund locks in an interest rate at a future settlement date. If the interest rate on the settlement date exceeds the lock rate, the Fund pays the seller the difference between the two rates. If the lock rate exceeds the interest rate on the settlement date, the seller pays the Fund the difference between the two rates. Any such gain received by the Fund would be taxable. These instruments are traded in the OTC market.

Equity Swaps. Equity swaps involve the exchange by the Fund with another party of their respective returns as calculated on a notional amount of an equity index (such as the S&P 500® Index), basket of equity securities, or individual equity security.

Equity-Linked Securities. Equity-linked securities are primarily used as an alternative means to more efficiently and effectively access the securities markets of emerging market countries and may also be known as participation notes, equity swaps, and zero strike calls and warrants. Equity-linked securities are privately issued securities whose investment results are designed to correspond generally to the performance of a specified stock index or “basket” of stocks, or sometimes a single stock. The Fund deposits an amount of cash with its custodian (or broker, if legally permitted) in an amount near or equal to the selling price of the underlying security in exchange for an equity-linked security. Upon sale, the Fund receives cash from the broker or custodian equal to the current value of the underlying security.

In addition to the risks of the underlying security, there is the risk that the issuer of an equity-linked security may default on its obligation under the security. In addition, there can be no assurance that the Fund will be able to close out such a transaction with the other party or obtain an offsetting position with any other party, at any time prior to the end of the term of the underlying agreement. This may impair the Fund’s ability to enter into other transactions at a time when doing so might be advantageous.

Interest Rate Swaps. Interest rate swaps involve the exchange by the Fund with another party of their respective commitments to pay or receive interest, e.g., an exchange of fixed rate payments for floating-rate payments.

Credit Default Swaps. Credit default swap agreements (“CDS”) enable the Fund to buy or sell credit protection on an individual issuer or basket of issuers (i.e., the reference instrument). The Fund may enter into CDS to gain or short exposure to a reference instrument. Long CDS positions are utilized to gain exposure to a reference instrument (similar to buying the instrument) and are akin to selling insurance on the instrument. Short CDS positions are utilized to short exposure to a reference instrument (similar to shorting the instrument) and are akin to buying insurance on the instrument.

Under a CDS, the protection “buyer” in a credit default contract is generally obligated to pay the protection “seller” an upfront or a periodic stream of payments over the term of the contract, provided that no credit event, such as a default, on a reference instrument has occurred. If a credit event occurs, the seller generally must pay the buyer the “par value” (full notional value) of the reference instrument in exchange for an equal face amount of the reference instrument described in the swap, or the seller may be required to deliver the related net cash amount, if the swap is

Eaton Vance Richard Bernstein Funds22Prospectus dated January 1, 2022

cash settled. If the Fund is a buyer and no credit event occurs, the Fund may recover nothing if the swap is held through its termination date. As a seller, the Fund generally receives an upfront payment or a fixed rate of income throughout the term of the swap provided that there is no credit event. The Fund’s obligations under a CDS will be accrued daily (offset against any amounts owed to the Fund).

In response to market events, federal and certain state regulators have proposed regulation of the CDS market. These regulations may limit the Fund’s ability to use CDS and/or the benefits of CDS. CDS may be difficult to value and generally pay a return to the party that has paid the premium only in the event of an actual default by the issuer of the underlying obligation (as opposed to a credit downgrade or other indication of financial difficulty). The Fund may have difficulty, be unable or may incur additional costs to acquire any securities or instruments it is required to deliver under a CDS. The Fund many have limited ability to eliminate its exposure under a CDS either by assignment or other disposition, or by entering into an offsetting swap agreement. The Fund also may have limited ability to eliminate its exposure under a CDS if the reference instrument has declined in value.

Credit Options. Credit options are options whereby the purchaser has the right, but not the obligation, to enter into a transaction involving either an asset with inherent credit risk or a credit derivative at terms specified at the inception of the option.

Credit Linked Notes. A credit linked note (“CLN”) is a type of hybrid instrument in which a special purpose entity issues a structured note (the “note issuer”) with respect to which the reference instrument is a single bond, a portfolio of bonds or the unsecured credit of an issuer, in general (each a “reference credit”). The purchaser of the CLN (the “note purchaser”) invests a par amount and receives a payment during the term of the CLN that equals a fixed or floating rate of interest equivalent to a high rated funded asset (such as a bank certificate of deposit) plus an additional premium that relates to taking on the credit risk of the reference credit. Upon maturity of the CLN, the note purchaser will receive a payment equal to: (i) the original par amount paid to the note issuer, if there is no occurrence of a designated event of default, restructuring or other credit event (each a “credit event”) with respect to the issuer of the reference credit; or (ii) the market value of the reference credit, if a credit event has occurred. Depending upon the terms of the CLN, it is also possible that the note purchaser may be required to take physical delivery of the reference credit in the event of a credit event. Most CLNs use a corporate bond (or a portfolio of corporate bonds) as the reference credit. However, almost any type of fixed-income security (including foreign government securities), index or derivative contract (such as a credit default swap) can be used as the reference credit.

Inflation Swaps. Inflation swaps involve the exchange by the Fund with another party of their respective commitments to pay or receive interest. This can involve an exchange of fixed rate payments for floating rate payments based on a reference index (an inflation index, such as the Consumer Price Index) or an exchange of floating rate payments based on two different reference indices where one of the reference indices is an inflation index. Inflation swaps can be designated as zero coupon, where both sides of the swap compound interest over the life of the swap and then the accrued interest is paid in a lump sum at the swap’s maturity.

Total Return Swaps. A total return swap is a contract in which one party agrees to make periodic payments to another party based on the change in market value of a reference instrument during the specified period, in return for periodic payments from the other party that are based on a fixed or variable interest rate or the total return of the reference instrument or another reference instrument. Total return swap agreements may be used to obtain exposure to a security or market without owning or taking physical custody of such security or investing directly in such market.

Counterparty Risk. A financial institution or other counterparty with whom the Fund does business (such as trading, securities lending or as a derivatives counterparty), or that underwrites, distributes or guarantees any instruments that the Fund owns or is otherwise exposed to, may decline in financial condition and become unable to honor its commitments. This could cause the value of Fund shares to decline or could delay the return or delivery of collateral or other assets to the Fund. Counterparty risk is increased for contracts with longer maturities.

Short Sales. The Fund may engage in short sales on securities or a basket or index of securities. A short sale on an individual security typically involves the sale of a security that is borrowed from a broker or other institution to complete the sale. When making a short sale, the Fund must segregate liquid assets with a broker or the custodian equal to (or otherwise cover) its obligations under the short sale. Generally, securities held in a segregated account cannot be sold unless they are replaced with other liquid assets. This may limit the Fund’s investment flexibility, as well as its ability to meet redemption requests or other current obligations. The seller of a short position generally realizes a profit from the transaction if the proceeds it receives on the short sale exceed the cost of purchasing the securities sold short in the market, but will generally realize a loss if the cost of closing the short position exceeds the proceeds from the short sale. The Fund pays interest or dividend expense with respect to securities sold short.

Eaton Vance Richard Bernstein Funds23Prospectus dated January 1, 2022

will decline in value or make a profit for the Fund. In addition, there is no guarantee that any security needed to cover the short position will be available for purchase. Short selling carries a risk that the counterparty to the short sale may fail to honor its contract terms, causing a loss to the Fund. Further, if other short positions of the same security are closed out at the same time, a “short squeeze” can occur where demand exceeds the supply for the security sold short. A short squeeze makes it more likely that the Fund will need to replace the borrowed security at an unfavorable price. If the Fund invests the proceeds received for selling securities short in other investments, the Fund is employing a form of leverage.

Forward Commitments and When-Issued Securities. The Fund may purchase securities on a “forward commitment” or “when-issued” basis (meaning securities are purchased or sold with payment and delivery taking place in the future). In such a transaction, the Fund is securing what is considered to be an advantageous price and yield at the time of entering into the transaction.

The yield on a comparable security when the transaction is consummated may vary from the yield on the security at the time that the forward commitment or when-issued transaction was made. From the time of entering into the transaction until delivery and payment is made at a later date, the securities that are the subject of the transaction are subject to market fluctuations. In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous. Forward commitment or when-issued transactions may be expected to occur a month or more before delivery is due. No payment or delivery is made, however, until payment is received or delivery is made from the other party to the transaction. These transactions may create leverage in the Fund.

Credit Risk. Investments in debt instruments are subject to the risk of non-payment of scheduled principal and interest. Changes in economic conditions or other circumstances may reduce the capacity of the party obligated to make principal and interest payments on such instruments and may lead to defaults. Such non-payments and defaults may reduce the value of Fund shares and income distributions. The value of debt instruments also may decline because of concerns about the issuer’s ability to make principal and interest payments. In addition, the credit ratings of debt instruments may be lowered if the financial condition of the party obligated to make payments with respect to such instruments deteriorates. In the event of bankruptcy of the issuer of a debt instrument, the Fund could experience delays or limitations with respect to its ability to realize the benefits of any collateral securing the instrument. In order to enforce its rights in the event of a default, bankruptcy or similar situation, the Fund may be required to retain legal or similar counsel, which may increase the Fund’s operating expenses and adversely affect net asset value. The Fund is also exposed to credit risk when it engages in certain types of derivatives transactions and when it engages in transactions that expose the Fund to counterparty risk. See “Derivatives.”

In evaluating the quality of a particular instrument, the investment adviser (or sub-adviser, if applicable) may take into consideration, among other things, a credit rating assigned by a credit rating agency, the issuer’s financial resources and operating history, its sensitivity to economic conditions and trends, the ability of its management, its debt maturity schedules and borrowing requirements, and relative values based on anticipated cash flow, interest and asset coverage, and earnings prospects. Credit rating agencies are private services that provide ratings of the credit quality of certain investments. Credit ratings issued by rating agencies are based on a number of factors including, but not limited to, the issuer’s financial condition and the rating agency’s credit analysis, if applicable, at the time of rating. As such, the rating assigned to any particular security is not necessarily a reflection of the issuer’s current financial condition. The ratings assigned are not absolute standards of credit quality and do not evaluate market risks or necessarily reflect the issuer’s current financial condition or the volatility or liquidity of the security.

For purposes of determining compliance with the Fund’s credit quality restrictions, if any, the Fund’s investment adviser (or sub-adviser, if applicable) relies primarily on the ratings assigned by credit rating agencies but may, in the case of unrated instruments, perform its own credit and investment analysis to determine an instrument’s credit quality. A credit rating may have a modifier (such as plus, minus or a numerical modifier) to denote its relative status within the rating. The presence of a modifier does not change the security credit rating (for example, BBB- and Baa3 are within the investment grade rating) for purposes of the Fund’s investment limitations.

Lower Rated Investments. Investments in obligations rated below investment grade and comparable unrated securities (sometimes referred to as “junk”) generally entail greater economic, credit and liquidity risks than investment grade securities. Lower rated investments have speculative characteristics because of the credit risk associated with their issuers. Changes in economic conditions or other circumstances typically have a greater effect on the ability of issuers of lower rated investments to make principal and interest payments than they do on issuers of higher rated investments. An economic downturn generally leads to a higher non-payment rate, and a lower rated investment may lose significant value before a default occurs. Lower rated investments generally are subject to greater price volatility and illiquidity than higher rated investments.

Eaton Vance Richard Bernstein Funds24Prospectus dated January 1, 2022

Because of the greater number of investment considerations involved in investing in investments that receive lower ratings, investing in lower rated investments depends more on the investment adviser’s judgment and analytical abilities than may be the case for investing in investments with higher ratings. While the investment adviser will attempt to reduce the risks of investing in lower rated or unrated securities through, among other things, active portfolio management, credit analysis and attention to current developments and trends in the economy and the financial markets, there can be no assurance that the investment adviser will be successful in doing so.

Asset-Backed Securities. Asset-Backed securities represent interests in a pool of assets other than mortgages, such as home equity loans, automobile receivables or credit card receivables. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income asset (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. A structured asset-backed security is a multiclass instrument that is typically backed by a pool of auto loans, credit card receivables, home equity loans or student loans.

Unscheduled prepayments of asset-backed securities may result in a loss of income if the proceeds are invested in lower-yielding securities. Conversely, in a rising interest rate environment, a declining prepayment rate will extend the average life of many asset-backed securities, which increases the risk of depreciation due to future increases in market interest rates. In addition, issuers of asset-backed securities may have limited ability to enforce the security interest in the underlying assets, and credit enhancements (if any) may be inadequate in the event of default. Asset-backed securities may experience losses on the underlying assets as a result of certain rights provided to consumer debtors under federal and state law. The value of asset-backed securities may be affected by the factors described above and other factors, such as interest rate risk, the availability of information concerning the pool and its structure, the creditworthiness of the servicing agent for the pool, the originator of the underlying assets or the entities providing credit enhancements and the ability of the servicer to service the underlying collateral. The value of asset-backed securities representing interests in a pool of utilities receivables may be adversely affected by changes in government regulations. Under certain market conditions, asset-backed securities may be less liquid and may be difficult to value. If a structured asset-backed security is subordinated to other classes backed by the same pool of collateral, the likelihood that it will make payments of principal may be substantially limited.

Mortgage-Backed Securities (“MBS”). MBS represent participation interests in pools of adjustable and fixed-rate mortgage loans. MBS may be issued by the U.S. Government (or one of its agencies or instrumentalities) or privately issued but collateralized by mortgages that are insured, guaranteed or otherwise backed by the U.S. Government, or its agencies or instrumentalities. Adjustable rate mortgages are mortgages whose interest rates are periodically reset when market rates change. Unlike conventional debt obligations, MBS provide monthly payments derived from the monthly interest and principal payments (including any prepayments) made by the individual borrowers on the pooled mortgage loans.

MBS include classes of collateralized mortgage obligations (“CMOs”), including fixed- or floating-rate tranches, and various other MBS. In choosing among CMO classes, the investment adviser will evaluate the total income potential of each class and other factors.

MBS issued by non-government entities are subject to the risks that the underlying mortgage borrowers fail to make timely payments of interest and principal and that any guarantee or other structural feature, if present, is insufficient to enable the timely payment of interest and principal on the MBS. Although certain MBS are guaranteed as to timely payment of interest and principal by a government-sponsored entity, the market price for such securities is not guaranteed and will fluctuate.

The mortgage loans underlying MBS are generally subject to a greater rate of principal prepayments in a declining interest rate environment and to a lesser rate of principal prepayments in an increasing interest rate environment, although investment in seasoned MBS can mitigate this risk. Under certain interest and prepayment rate scenarios, the Fund may fail to recover the full amount of its investment in MBS, notwithstanding any direct or indirect governmental or agency guarantee. Because faster than expected prepayments must usually be invested in lower yielding securities, MBS are less effective than conventional bonds in “locking in” a specified interest rate. For premium bonds, the risk of prepayment may be enhanced. In a rising interest rate environment, a declining prepayment rate will extend the average life of many MBS. This possibility is often referred to as extension risk. Extending the average life of a mortgage-backed security increases the risk of depreciation due to future increases in market interest rates. MBS that are purchased at a premium generate current income that exceeds market rates for comparable investments, but tend to decrease in value as they mature.

CMOs are subject to the same types of risks affecting MBS as described above. CMOs with complex or highly variable prepayment terms generally entail greater market and liquidity risks than other MBS. For example, their prices are more volatile and their trading market may be more limited. The structure of certain CMO interests held by the Fund may cause

Eaton Vance Richard Bernstein Funds25Prospectus dated January 1, 2022

the Fund to be paid interest and/or principal on its investment only after holders of other interests in that particular CMO have received the full repayment of principal or interest on their investments.

Commercial Mortgage-Backed Securities. Commercial mortgage-backed securities (“CMBS”) include securities that reflect an interest in, and are secured by, mortgage loans on commercial real property, such as loans for hotels, shopping centers, office buildings and apartment buildings. Generally, the interest and principal payments on these loans are passed on to investors in CMBS according to a schedule of payments.

CMBS are subject to the risks described under “Asset-Backed Securities” above. CMBS also are subject to many of the risks of investing in the real estate securing the underlying mortgage loans and are therefore different from the risks of other types of mortgage-backed securities. These risks reflect the effects of local and other economic conditions on real estate markets, the ability of tenants to make loan payments, and the ability of a property to attract and retain tenants. CMBS may be less liquid and exhibit a greater price volatility than other types of mortgage- or asset-backed securities.

The commercial mortgage loans that underlie CMBS have certain distinct risk characteristics. Commercial mortgage loans generally lack standardized terms, which may complicate their structure, tend to have shorter maturities than residential mortgage loans and may not be fully amortizing. Commercial properties themselves tend to be unique and are more difficult to value than single-family residential properties. In addition, commercial properties, particularly industrial and warehouse properties, are subject to environmental risks and the burdens and costs of compliance with environmental laws and regulations.

Zero Coupon and Deep Discount Bonds and Payment-in-Kind (“PIK”) Securities. Zero coupon bonds are debt obligations that do not require the periodic payment of interest and are issued at a significant discount from face value. The discount approximates the total amount of interest the bonds will accrue and compound over the period until maturity at a rate of interest reflecting the market rate of the security at the time of purchase. The effect of owning debt obligations that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the debt obligation. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the holder’s ability to reinvest at higher rates in the future. Deep discount bonds also are issued at a discount from face value, but may make periodic interest payments at a below market interest rate.

PIK securities generally carry higher interest rates compared to bonds that make cash payments of interest to reflect their payment deferral and increased credit risk. PIK interest has the effect of generating investment income and increasing the incentive fees, if any, payable at a compounding rate. Generally, the deferral of PIK interest increases the loan to value ratio.

Bonds and preferred stocks that make “in-kind” payments and other securities that do not pay regular income distributions may experience greater volatility in response to interest rate changes and issuer developments. PIK securities generally involve significantly greater credit risk than coupon loans because the Fund receives no cash payments until the maturity date or a specified cash payment date. Even if accounting conditions are met for accruing income payable at a future date under a PIK bond, the issuer could still default when the collection date occurs at the maturity of or payment date for the PIK bond. PIK bonds may be difficult to value accurately because they involve ongoing judgments as to the collectability of the deferred payments and the value of any associated collateral. If the issuer of a PIK security defaults, the Fund may lose its entire investment.

The Fund is required to accrue income from zero coupon and deep discount bonds and PIK securities on a current basis, even though it does not receive that income currently in cash, and the Fund is required to distribute that income for each taxable year. Such distributions could reduce the Fund’s cash position and require it to sell securities and incur a gain or loss at a time it may not otherwise want to in order to provide the cash necessary for these distributions.

U.S. Treasury and Government Securities. U.S. Treasury securities (“Treasury Securities”) include U.S. Treasury obligations that differ in their interest rates, maturities and times of issuance. U.S. Government agency securities (“Agency Securities”) include obligations issued or guaranteed by U.S. Government agencies or instrumentalities and government-sponsored enterprises. Agency Securities may be guaranteed by the U.S. Government or they may be backed by the right of the issuer to borrow from the U.S. Treasury, the discretionary authority of the U.S. Government to purchase the obligations, or the credit of the agency, instrumentality or enterprise.

Government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”), the Federal Home Loan Banks (“FHLBs”), the Private Export Funding Corporation (“PEFCO”), the Federal Deposit Insurance Corporation (“FDIC”), the Federal Farm Credit Banks (“FFCB”) and the Tennessee Valley Authority (“TVA”), although chartered or sponsored by Congress, are not funded by congressional appropriations and the debt and mortgage-backed securities issued by them are neither guaranteed nor

Eaton Vance Richard Bernstein Funds26Prospectus dated January 1, 2022

issued by the U.S. Government. Treasury Securities and Agency Securities also include any security or agreement collateralized or otherwise secured by Treasury Securities or Agency Securities, respectively.

Because of their high credit quality and market liquidity, U.S. Treasury and Agency Securities generally provide a lower current return than obligations of other issuers. While the U.S. Government has provided financial support to Fannie Mae and Freddie Mac in the past, there can be no assurance that it will support these or other government-sponsored enterprises in the future.

Pooled Investment Vehicles. The Fund may invest in pooled investment vehicles. Pooled investment vehicles are open- and closed-end investment companies unaffiliated with the investment adviser, open-end investment companies affiliated with the investment adviser and exchange-traded funds (“ETFs”). Pooled investment vehicles are subject to the risks of investing in the underlying securities or other instruments that they own. The market for common shares of closed-end investment companies and ETFs, which are generally traded on an exchange and may be traded at a premium or discount to net asset value, is affected by the demand for those securities, regardless of the value of such fund’s underlying securities. Additionally, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events could result in increased premiums or discounts to such fund’s net asset value. The Fund will indirectly bear its proportionate share of any management fees and other operating expenses paid by unaffiliated and certain affiliated pooled investment vehicles in which it invests. If such fees exceed 0.01%, the costs associated with such investments will be reflected under Acquired Fund Fees and Expenses in the Fund’s Annual Fund Operating Expenses table(s) in its Fund Summary. Requirements of the 1940 Act may limit the Fund’s ability to invest in other investment companies, including ETFs, unless the investment company has received an exemptive order from the SEC on which the Fund may rely. Investments in a pooled investment vehicle will count towards a Fund's 80% Policy (or other investment ranges described herein) if the vehicle invests at least 80% of its net assets in the type of securities included in the Fund's 80% Policy or other investment policy.

The Fund may invest in exchange-traded notes (“ETNs”), which are debt securities that typically are listed on exchanges and their terms generally provide for a return that tracks specified market indices. ETNs may not trade in the secondary market, but typically are redeemable by the issuer.

Unlike ETFs and closed-end investment companies, ETNs are not registered investment companies and thus are not regulated under the 1940 Act. While ETNs do not have management fees, they are subject to certain investor fees. In addition, as debt securities, ETNs are subject to the additional credit risk of the issuer.

Preferred Stock. Preferred stock is a class of equity security that pays a specified dividend that typically must be paid before any dividends can be paid to common stockholders and takes precedence over common stock in the event of the issuer’s liquidation. Although preferred stocks represent an ownership interest in an issuer, preferred stocks generally do not have voting rights or have limited voting rights and have economic characteristics similar to fixed-income securities. Preferred stocks generally are issued with a fixed par value and pay dividends based on a percentage of that par value at a fixed or variable rate. Dividend payments on preferred stocks may be subordinate to interest payments on the issuer’s debt obligations. Certain preferred stocks may be convertible to common stock. Additionally, preferred stocks often have a liquidation value that generally equals the original purchase price of the preferred stock at the date of issuance.

Preferred stocks are subject to issuer-specific and market risks generally applicable to equity securities and credit and interest rate risks generally applicable to fixed-income securities. The value of preferred stock may react more strongly than bonds and other debt instruments to actual or perceived changes in the company’s financial condition or prospects. Preferred stocks are considered an equity security.

Smaller Companies. Securities of smaller companies, which may include legally restricted securities, are generally subject to greater price fluctuations, limited liquidity, higher transaction costs and higher investment risk than the securities of larger, more established companies. Because of the absence of any public trading market for some of these investments (such as those which are legally restricted) it may be more difficult to value these investments and may take longer to liquidate these positions at fair value than would be the case for publicly traded securities.

Real Estate Investments. Companies primarily engaged in the real estate industry and other real estate-related investments may include publicly traded real estate investment trusts (“REITs”) or real estate operating companies that either own properties or make construction or mortgage loans, real estate developers, companies with substantial real estate holdings and other companies whose products and services are related to the real estate industry, such as lodging operators, brokers, property management companies, building supply manufacturers, mortgage lenders, or mortgage servicing companies. REITs tend to be small to medium-sized companies, and may include equity REITs and mortgage REITs. The value of a REIT can depend on the structure of and cash flow generated by the REIT. REITs are pooled investment vehicles that have expenses of their own, so the Fund will indirectly bear its proportionate share of those expenses. The Fund will not own real estate directly.

Eaton Vance Richard Bernstein Funds27Prospectus dated January 1, 2022

Real estate investments are subject to special risks including changes in real estate values, property taxes, interest rates, cash flow of underlying real estate assets, occupancy rates, government regulations affecting zoning, land use, and rents, and the management skill and creditworthiness of the issuer. Companies in the real estate industry may also be subject to liabilities under environmental and hazardous waste laws, among others. Changes in underlying real estate values may have an exaggerated effect to the extent that investments concentrate in particular geographic regions or property types.

Equity REITs may be affected by changes in the value of the underlying property owned by the REIT, while mortgage REITs may be affected by the quality of any credit extended. Further, equity and mortgage REITs are dependent upon management skills and generally may not be diversiﬁed. Equity and mortgage REITs are also subject to heavy cash ﬂow dependency, defaults by borrowers, and self-liquidations. In addition, equity and mortgage REITs could possibly fail to qualify for tax-free pass-through of income or to maintain their exemptions from registration under the 1940 Act. The above factors may also adversely affect a borrower’s or a lessee’s ability to meet its obligations to a REIT. In the event of a default by a borrower or lessee, a REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting its investments.

Shares of REITs may trade less frequently and, therefore, are subject to more erratic price movements than securities of larger issuers. REITs are also subject to credit, market, liquidity and interest rate risks.

REITs may issue debt securities to fund their activities. The value of these debt securities may be affected by changes in the value of the underlying property owned by the REIT, the creditworthiness of the REIT, interest rates, and tax and regulatory requirements, among other things.

Municipal Obligations. Municipal obligations include bonds, notes, floating-rate notes and commercial paper issued by a municipality, a group of municipalities or participants in qualified issues of municipal debt for a wide variety of both public and private purposes. Revenue bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as payments from the user of the facility being financed. Municipal obligations also include municipal lease obligations and certificates of participations in municipal leases. A municipal lease obligation is a bond that is secured by lease payments made by the party, typically a state or municipality, leasing the facilities (e.g., schools or office buildings) that were financed by the bond. Such lease payments may be subject to annual appropriation or may be made only from revenues associated with the facility financed. In other cases, the leasing state or municipality is obligated to appropriate funds from its general tax revenues to make lease payments as long as it utilizes the leased property. A certificate of participation (also referred to as a “participation”) in a municipal lease is an instrument evidencing a pro rata share in a specific pledged revenue stream, usually lease payments by the issuer that are typically subject to annual appropriation. The certificate generally entitles the holder to receive a share, or participation, in the payments from a particular project.

Certain municipal obligations may be purchased on a “when-issued” basis, which means that payment and delivery occur on a future settlement date. The price and yield of such securities are generally fixed on the date of commitment to purchase.

The Fund may invest in zero coupon bonds, which do not make cash interest payments during a portion or all of the life of the bond. Instead, such bonds are sold at a deep discount to face value, and the interest consists of the gradual appreciation in price as the bond approaches maturity. Zero coupon bonds can be an attractive financing method for issuers with near-term cash-flow problems or seeking to preserve liquidity. Principal only investments entitle the Fund to receive the stated value of such investment when held to maturity.

Certain municipal obligations are issued with interest rates that adjust periodically. Such municipal floating-rate debt obligations are generally indexed to LIBOR, the Securities Industry and Financial Markets Association index, the Consumer Price Index or other indices. Municipal floating-rate debt obligations include, but are not limited to, municipal floating-rate notes, floating-rate notes issued by tender option bond trusts, auction rate preferred securities, synthetic floating-rate securities (e.g., a fixed-rate instrument that is subject to a swap agreement converting a fixed rate to a floating rate) and other municipal instruments with floating interest rates (such as variable rate demand preferred shares and variable rate term preferred shares).

The interest on tax-exempt municipal obligations is (in the opinion of the issuer’s counsel) exempt from regular federal income and state or local taxes, as applicable. Income from certain types of municipal obligations generally may be subject to the federal alternative minimum tax (the “AMT”) for individuals. Investors subject to AMT should consult their tax advisors.

Issuers of general obligation bonds include states, counties, cities, towns and regional districts. The proceeds of these obligations are used to fund a wide range of public projects, including the construction or improvement of schools, highways and roads, water and sewer systems and a variety of other public purposes. The basic security of general

Eaton Vance Richard Bernstein Funds28Prospectus dated January 1, 2022

obligation bonds is the issuer’s pledge of its faith, credit, and taxing power for the payment of principal and interest. The taxes that can be levied for the payment of debt service may be limited or unlimited as to rate and amount. General obligation bonds issued by municipalities can be adversely affected by economic downturns and the resulting decline in tax revenues, pension funding risk, other post-employment benefit risk, budget imbalances, taxing ability risk, lack of political willpower and federal funding risk, among others. Revenue bonds can be adversely affected by the negative economic viability of the facility or revenue source. Many municipal obligations provide the issuer the option to “call,” or redeem, its securities. As such, the effective maturity of a municipal obligation may be reduced as the result of such call provisions and, if an investment is called in a declining interest rate environment, the proceeds from the called bond may have to be reinvested at a lower interest rate.

The values of zero coupon bonds and principal only investments are subject to greater fluctuation in response to changes in market interest rates than municipal obligations that pay interest currently. The Fund is required to distribute to shareholders income imputed to any zero coupon bonds or principal only investments even though such income may not be received by the Fund as distributable cash. Such distributions could reduce the Fund’s reserve position and require it to sell securities and incur a gain or loss at a time it may not otherwise want to in order to provide the cash necessary for these distributions.

Loans. Loans may be primary, direct investments or investments in loan assignments or participation interests. A loan assignment represents a portion or the entirety of a loan and a portion or the entirety of a position previously attributable to a different lender. The purchaser of an assignment typically succeeds to all the rights and obligations under the loan agreement and has the same rights and obligations as the assigning investor. However, assignments through private negotiations may cause the purchaser of an assignment to have different and more limited rights than those held by the assigning investor. Loan participation interests are interests issued by a lender or other entity and represent a fractional interest in a loan. The Fund typically will have a contractual relationship only with the financial institution that issued the participation interest. As a result, the Fund may have the right to receive payments of principal, interest and any fees to which it is entitled only from the financial institution and only upon receipt by such entity of such payments from the borrower. In connection with purchasing a participation interest, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement, nor any rights with respect to any funds acquired by other investors through set-off against the borrower and the Fund may not directly benefit from the collateral supporting the loan in which it has purchased the participation interest. As a result, the Fund may assume the credit risk of both the borrower and the financial institution issuing the participation interest. In the event of the insolvency of the entity issuing a participation interest, the Fund may be treated as a general creditor of such entity. Most loans are rated below investment grade or, if unrated, are of similar credit quality.

Loan investments may be made at par or at a discount or premium to par. The interest payable on a loan may be fixed or floating rate, and paid in cash or in-kind. In connection with transactions in loans, the Fund may be subject to facility or other fees. Loans may be secured by specific collateral or other assets of the borrower, guaranteed by a third party, unsecured or subordinated. During the term of a loan, the value of any collateral securing the loan may decline in value, causing the loan to be under collateralized. Collateral may consist of assets that may not be readily liquidated, and there is no assurance that the liquidation of such assets would satisfy fully a borrower’s obligations under the loan. In addition, if a loan is foreclosed, the Fund could become part owner of the collateral and would bear the costs and liabilities associated with owning and disposing of such collateral.

Certain loans (“senior loans”) hold a senior position in the capital structure of a business entity, are typically secured with specific collateral and have a claim on the assets and/or stock of the borrower that is senior to that held by subordinated debtholders and stockholders of the borrower. Junior loans may be secured or unsecured subordinated loans, second lien loans and subordinated bridge loans. Floating-rate loans typically have rates of interest which are re-determined daily, monthly, quarterly or semi-annually by reference to a base lending rate, plus a premium.

A lender’s repayment and other rights primarily are determined by governing loan, assignment or participation documents, which (among other things) typically establish the priority of payment on the loan relative to other indebtedness and obligations of the borrower. A borrower typically is required to comply with certain covenants contained in a loan agreement between the borrower and the holders of the loan. The types of covenants included in loan agreements generally vary depending on market conditions, the creditworthiness of the issuer, and the nature of the collateral securing the loan. Loans with fewer covenants that restrict activities of the borrower may provide the borrower with more flexibility to take actions that may be detrimental to the loan holders and provide fewer investor protections in the event covenants are breached. The Fund may experience relatively greater realized or unrealized losses or delays and expense in enforcing its rights with respect to loans with fewer restrictive covenants. Loans to entities located outside of the U.S. (including loans to sovereign entities) may have substantially different lender protections and covenants as compared to loans to U.S. entities and may involve greater risks. In the event of bankruptcy, applicable law may impact a lender’s ability to enforce its rights. Bankruptcy laws in foreign jurisdictions, including emerging markets, may differ significantly

Eaton Vance Richard Bernstein Funds29Prospectus dated January 1, 2022

from U.S. bankruptcy law and the Fund’s rights with respect to a loan governed by the laws of a foreign jurisdiction may be more limited. Sovereign entities may be unable or unwilling to meet their obligations under a loan due to budgetary limitations or economic or political changes within the country.

Loans may be originated by a lending agent, such as a financial institution or other entity, on behalf of a group or “syndicate” of loan investors (the “Loan Investors”). In such a case, the agent administers the terms of the loan agreement and is responsible for the collection of principal, and interest payments from the borrower and the apportionment of these payments to the Loan Investors. Failure by the agent to fulfill its obligations may delay or adversely affect receipt of payment by the Fund. Furthermore, unless under the terms of a loan agreement or participation (as applicable) the Fund has direct recourse against the borrower, the Fund must rely on the agent and the other Loan Investors to pursue appropriate remedies against the borrower.

Although the overall size and number of participants in the market for many loans has grown over the past decade, such loans continue to trade in a private, unregulated inter-dealer or inter-bank secondary market and the amount of available public information about loans may be less extensive than that available for registered or exchange listed securities. With limited exceptions, the investment adviser will take steps intended to insure that it does not receive material nonpublic information about the issuers of loans that also issue publicly traded securities. Therefore, the investment adviser may have less information than other investors about certain of the loans in which it seeks to invest. Purchases and sales of loans are generally subject to contractual restrictions that must be satisfied before a loan can be bought or sold. These restrictions may (i) impede the Fund’s ability to buy or sell loans, (ii) negatively impact the transaction price, (iii) impact the counterparty and/or credit risks borne by the Fund, (iv) impede the Fund’s ability to timely vote or otherwise act with respect to loans, (v) expose the Fund to adverse tax or regulatory consequences and/or (vi) result in delayed settlement of loan transactions. It may take longer than seven days for a transaction in loans to settle, which may impact the Fund’s process for meeting redemptions. See “Liquidity Risk.” This is partly due to the nature of manner in which loans trade and the contractual restrictions noted above, which require a written assignment agreement and various ancillary documents for each transfer, and frequently require discretionary consents from both the borrower and the administrative agent. In light of the foregoing, the Fund may hold cash, sell investments or temporarily borrow to meet its cash needs, including satisfying redemption requests.

Assignments of loans through private negotiations may cause the purchaser of an assignment to have different and more limited rights than those held by the assigning investor. In connection with purchasing a participation interest, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement. In the event the borrower defaults, the Fund may not directly benefit from the collateral supporting the loan (if any) in which it has purchased the participation interest. As a result, the Fund may assume the credit risk of both the borrower and the financial institution issuing the participation interest. No active trading market may exist for certain loans, which may impair the ability of the Fund to realize full value in the event of the need to sell a loan and which may make it difficult to value the loan. To the extent that a secondary market does exist for certain loans, the market may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods.

In addition to the risks generally associated with debt instruments, such as credit, market, interest rate and liquidity risks, loans are also subject to the risk that the value of any collateral securing a loan may decline, be insufficient to meet the obligations of the borrower or be difficult to liquidate. The specific collateral used to secure a loan may decline in value or become illiquid, which would adversely affect the loan’s value. The Fund’s access to collateral may be limited by bankruptcy, other insolvency laws or by the type of loan the Fund has purchased. For example, if the Fund purchases a participation instead of an assignment, it would not have direct access to collateral of the borrower. As a result, a floating-rate loan may not be fully collateralized and can decline significantly in value. Additionally, collateral on loan instruments may not be readily liquidated, and there is no assurance that the liquidation of such assets will satisfy a borrower’s obligations under the investment.

Loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate a loan to presently existing or future indebtedness of the borrower, or take other action detrimental to the holders of a loan including, in certain circumstances, invalidating a loan or causing interest previously paid to be refunded to the borrower. Any such actions by a court could negatively affect the Fund’s performance. Loans that are secured and senior to other debtholders of a borrower tend to have more favorable loss recovery rates as compared to more junior types of below investment grade debt obligations. Due to their lower place in the borrower’s capital structure and, in some cases, their unsecured status, junior loans involve a higher degree of overall risk than senior loans of the same borrower.

Investing in loans involves the risk of default by the borrower or other party obligated to repay the loan. In the event of insolvency of the borrower or other obligated party, the Fund may be treated as a general creditor of such entity unless it has rights that are senior to that of other creditors or secured by specific collateral or assets of the borrower. Fixed rate loans are also subject to the risk that their value will decline in a rising interest rate environment. This risk is mitigated for floating-rate loans, where the interest rate payable on the loan resets periodically by reference to a base lending rate.

Eaton Vance Richard Bernstein Funds30Prospectus dated January 1, 2022

U.S. federal securities laws afford certain protections against fraud and misrepresentation in connection with the offering or sale of a security, as well as against manipulation of trading markets for securities. The typical practice of a lender in relying exclusively or primarily on reports from the borrower may involve the risk of fraud, misrepresentation, or market manipulation by the borrower. It is unclear whether U.S. federal securities law protections are available to an investment in a loan. In certain circumstances, loans may not be deemed to be securities, and in the event of fraud or misrepresentation by a borrower, lenders may not have the protection of the anti-fraud provisions of the federal securities laws. However, contractual provisions in the loan documents may offer some protections, and lenders may also avail themselves of common-law fraud protections under applicable state law.

Restricted Securities. Securities held by the Fund may be legally restricted as to resale (such as those issued in private placements), including commercial paper issued pursuant to Section 4(a)(2) of the 1933 Act, securities eligible for resale pursuant to Rule 144A thereunder, and securities of U.S. and non-U.S. issuers initially offered and sold outside the United States pursuant to Regulation S thereunder. Restricted securities may not be listed on an exchange and may have no active trading market. The Fund may incur additional expense when disposing of restricted securities, including all or a portion of the cost to register the securities. The Fund also may acquire securities through private placements under which it may agree to contractual restrictions on the resale of such securities that are in addition to applicable legal restrictions. In addition, if the investment adviser and/or sub-adviser, if applicable, receives non-public information about the issuer, the Fund may as a result be unable to sell the securities.

Restricted securities may be difficult to value properly and may involve greater risks than securities that are not subject to restrictions on resale. It may be difficult to sell restricted securities at a price representing fair value until such time as the securities may be sold publicly. Under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Fund could find it more difficult to sell such securities when the investment adviser and/or sub-adviser, if applicable, believes it advisable to do so or may be able to sell such securities only at prices lower than if such securities were more widely held. Holdings of restricted securities may increase the level of Fund illiquidity if eligible buyers become uninterested in purchasing them. Restricted securities may involve a high degree of business and financial risk, which may result in substantial losses.

LIBOR. The London Interbank Offered Rate or LIBOR is the average offered rate for various maturities of short-term loans between major international banks who are members of the British Bankers Association. LIBOR is the most common benchmark interest rate index used to make adjustments to variable-rate loans. It is used throughout global banking and financial industries to determine interest rates for a variety of financial instruments (such as debt instruments and derivatives) and borrowing arrangements. In July 2017, the Financial Conduct Authority (the “FCA”), the United Kingdom financial regulatory body, announced a desire to phase out the use of LIBOR. The ICE Benchmark Administration Limited, the administrator of LIBOR, is expected to cease publishing certain LIBOR settings on December 31, 2021, and the remaining LIBOR settings on June 30, 2023. Many market participants are in the process of transitioning to the use of alternative reference or benchmark rates.

Although the transition process away from LIBOR has become increasingly well-defined in advance of the anticipated discontinuation, the impact on certain debt securities, derivatives and other financial instruments that utilize LIBOR remains uncertain. The transition process may involve, among other things, increased volatility or illiquidity in markets for instruments that currently rely on LIBOR. The transition may also result in a change in (i) the value of certain instruments held by the Fund, (ii) the cost of temporary borrowing for the Fund, or (iii) the effectiveness of related Fund transactions such as hedges, as applicable.

Various financial industry groups are planning for the transition away from LIBOR, but there are obstacles to converting certain longer term securities and transactions to a new benchmark. In June 2017, the Alternative Reference Rates Committee, a group of large U.S. banks working with the Federal Reserve, announced its selection of a new Secured Overnight Financing Rate (“SOFR”), which is intended to be a broad measure of secured overnight U.S. Treasury repo rates, as an appropriate replacement for LIBOR. Bank working groups and regulators in other countries have suggested other alternatives for their markets, including the Sterling Overnight Interbank Average Rate (“SONIA”) in England. Both SOFR and SONIA, as well as certain other proposed replacement rates, are materially different from LIBOR, and changes in the applicable spread for financial instruments transitioning away from LIBOR need to be made to accommodate the differences. Liquid markets for newly-issued instruments that use an alternative reference rate are still developing. Consequently, there may be challenges for a Fund to enter into hedging transactions against instruments tied to alternative reference rates until a market for such hedging transactions develops.

Additionally, while some existing LIBOR-based instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative or “fallback” rate-setting methodology, there may be significant uncertainty regarding the effectiveness of any such alternative methodologies to replicate LIBOR. Not all existing LIBOR-based instruments have such fallback provisions, and many that do, do not contemplate the permanent cessation of LIBOR. While it is expected that market participants will amend legacy financial instruments referencing LIBOR to include fallback provisions to alternative reference rates, there remains uncertainty regarding the willingness and ability of parties to add or amend such fallback provisions in legacy instruments maturing after the end of 2021, particularly with respect to legacy cash products. Although there are ongoing efforts among certain government entities and other organizations to address these uncertainties, the ultimate effectiveness of such efforts is not yet known.

Any effects of the transition away from LIBOR and the adoption of alternative reference rates, as well as other unforeseen effects, could result in losses to the Fund. Since the usefulness of LIBOR as a benchmark could deteriorate during the transition period, these effects may occur prior to the discontinuation. Furthermore, the risks associated with the expected discontinuation of LIBOR and transition to replacement rates may be exacerbated if an orderly transition to an alternative reference rate is not completed in a timely manner.

Leverage. Certain types of Fund transactions may give rise to economic leverage, which represents a non-cash exposure to the underlying reference instrument. Leverage can increase both the risk and return potential of the Fund.

The Fund is required to segregate liquid assets or otherwise cover the Fund’s obligation created by a transaction that may give rise to leverage. The use of leverage may cause the Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet segregation requirements. Leverage may cause the Fund’s share price to be more volatile than if it had not been leveraged, as certain types of leverage may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. The loss on leveraged investments may substantially exceed the initial investment.

Liquidity Risk. The Fund is exposed to liquidity risk when trading volume, lack of a market maker, or legal restrictions impair the Fund’s ability to sell particular investments or close derivative positions at an advantageous market price. Trading opportunities are also more limited for securities and other instruments that are not widely held or are traded in less developed markets. These factors may make it more difficult to sell or buy a security at a favorable price or time. Consequently, the Fund may have to accept a lower price to sell an investment or continue to hold it or keep the position open, sell other investments to raise cash or abandon an investment opportunity, any of which could have a negative effect on the Fund’s performance. It also may be more difficult to value less liquid investments. These effects may be exacerbated during times of financial or political stress. Increased Fund redemption activity also may increase liquidity risk due to the need of the Fund to sell portfolio investments and may negatively impact Fund performance.

The Fund will not acquire any illiquid investment if, immediately after the acquisition, the Fund will have invested more than 15% of its net assets in illiquid investments. Illiquid investments mean any investments that the Fund’s investment adviser and/or sub-adviser, as applicable, reasonably expect cannot be sold or disposed of in seven calendar days or less under then-current market conditions without the sale or disposition significantly changing the market value of the investment.

Eaton Vance Richard Bernstein Funds31Prospectus dated January 1, 2022

Repurchase Agreements. A repurchase agreement is the purchase by the Fund of securities from a counterparty in exchange for cash that is coupled with an agreement to resell those securities to the counterparty at a specified date and price. Repurchase agreements maturing in more than seven days that the investment adviser believes may not be terminated within seven days at approximately the amount at which the Fund has valued the agreements are considered illiquid securities. When a repurchase agreement is entered into, the Fund typically receives securities with a value that equals or exceeds the repurchase price, including any accrued interest earned on the agreement. The value of such securities will be marked to market daily, and cash or additional securities will be exchanged between the parties as needed. Except in the case of a repurchase agreement entered into to settle a short sale, the value of the securities delivered to the Fund will be at least equal to the repurchase price during the term of the repurchase agreement. The terms of a repurchase agreement entered into to settle a short sale may provide that the cash purchase price paid by the Fund is more than the value of purchased securities that effectively collateralize the repurchase price payable by the counterparty. Since in such a transaction the Fund normally will have used the purchased securities to settle the short sale, the Fund will segregate liquid assets equal to the marked to market value of the purchased securities that it is obligated to return to the counterparty under the repurchase agreement.

In the event of the insolvency of the counterparty to a repurchase agreement, recovery of the repurchase price owed to the Fund may be delayed. In a repurchase agreement, such an insolvency may result in a loss to the extent that the value of the purchased securities decreases during the delay or that value has otherwise not been maintained at an amount equal to the repurchase price. Repurchase agreements may create leverage in the Fund.

Borrowing. The Fund is permitted to borrow for temporary purposes (such as to satisfy redemption requests, to remain fully invested in anticipation of expected cash inflows and to settle transactions). Any borrowings by the Fund are subject to the requirements of the 1940 Act. Borrowings are also subject to the terms of any credit agreement between the Fund and lender(s). Fund borrowings may be equal to as much as 331/3% of the value of the Fund’s total assets (including such borrowings) less the Fund’s liabilities (other than borrowings). The Fund will not purchase additional investments while outstanding borrowings exceed 5% of the value of its total assets.

In addition, the Fund will be required to maintain a specified level of asset coverage with respect to all borrowings and may be required to sell some of its holdings to reduce debt and restore coverage at times when it may not be advantageous to do so. The rights of the lender to receive payments of interest and repayments of principal of any borrowings made by the Fund under a credit facility are senior to the rights of holders of shares with respect to the payment of dividends or upon liquidation. In the event of a default under a credit arrangement, the lenders may have the right to cause a liquidation of the collateral (i.e., sell Fund assets) and, if any such default is not cured, the lenders may be able to control the liquidation as well.

Securities Lending. The Fund may lend its portfolio securities to broker-dealers and other institutional borrowers. During the existence of a loan, the Fund will continue to receive the equivalent of the interest paid by the issuer on the securities loaned, or all or a portion of the interest on investment of the collateral, if any. The Fund may pay lending fees to such borrowers. Loans will only be made to firms that have been approved by the investment adviser, and the investment adviser or the securities lending agent will periodically monitor the financial condition of such firms while such loans are outstanding. Securities loans will only be made when the investment adviser believes that the expected returns, net of expenses, justify the attendant risks. Securities loans currently are required to be secured continuously by collateral in cash, cash equivalents (such as money market instruments) or other liquid securities held by the custodian and maintained in an amount at least equal to the market value of the securities loaned. The Fund may engage in securities lending to generate income. Upon return of the loaned securities, the Fund would be required to return the related collateral to the borrower and may be required to liquidate portfolio securities in order to do so. The Fund may lend up to one-third of the value of its total assets or such other amount as may be permitted by law.

As with other extensions of credit, there are risks of delay in recovery or even loss of rights in the securities loaned if the borrower of the securities fails financially. To the extent that the portfolio securities acquired with such collateral have decreased in value, it may result in the Fund realizing a loss at a time when it would not otherwise do so. As such, securities lending may introduce leverage into the Fund. The Fund also may incur losses if the returns on securities that it acquires with cash collateral are less than the applicable rebate rates paid to borrowers and related administrative costs.

Cash and Money Market Instruments. The Fund may invest in cash or money market instruments, including high quality short-term instruments or an affiliated investment company that invests in such instruments. During unusual market conditions, the Fund may invest up to 100% of its assets in cash or money market instruments temporarily, which may be inconsistent with its investment objective(s) and other policies.

Eaton Vance Richard Bernstein Funds32Prospectus dated January 1, 2022

instruments; adverse economic, political or other developments affecting issuers of money market instruments; changes in the credit quality of issuers; and default by a counterparty.

Cybersecurity Risk. With the increased use of technologies by Fund service providers to conduct business, such as the Internet, the Fund is susceptible to operational, information security and related risks. The Fund relies on communications technology, systems, and networks to engage with clients, employees, accounts, shareholders, and service providers, and a cyber incident may inhibit the Fund’s ability to use these technologies. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber attacks include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites. A denial-of-service attack is an effort to make network services unavailable to intended users, which could cause shareholders to lose access to their electronic accounts, potentially indefinitely. Employees and service providers also may not be able to access electronic systems to perform critical duties for the Fund, such as trading and NAV calculation, during a denial-of-service attack. There is also the possibility for systems failures due to malfunctions, user error and misconduct by employees and agents, natural disasters, or other foreseeable and unforeseeable events.

Because technology is consistently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund and its service providers have experienced, and will continue to experience, cyber incidents consistently. In addition to deliberate cyber attacks, unintentional cyber incidents can occur, such as the inadvertent release of confidential information by the Fund or its service providers.

The Fund uses third party service providers who are also heavily dependent on computers and technology for their operations. Cybersecurity failures by or breaches of the Fund’s investment adviser or administrator and other service providers (including, but not limited to, the custodian or transfer agent), and the issuers of securities in which the Fund invests, may disrupt and otherwise adversely affect their business operations. This may result in financial losses to the Fund, impede Fund trading, interfere with the Fund’s ability to calculate its NAV, limit a shareholder’s ability to purchase or redeem shares of the Fund or cause violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, litigation costs, or additional compliance costs. While many of the Fund’s service providers have established business continuity plans and risk management systems intended to identify and mitigate cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified. The Fund cannot control the cybersecurity plans and systems put in place by service providers to the Fund and issuers in which the Fund invests. The Fund and its shareholders could be negatively impacted as a result.

Converting to Hub and Spoke Structure. The Fund may invest all of its investable assets in an open-end management investment company (“portfolio”) with substantially the same investment objective, policies and restrictions as the Fund. Any such portfolio would be advised by the Fund’s investment adviser (or an affiliate) and the Fund would not pay directly any advisory fee with respect to the assets so invested. The Fund may initiate investments in a portfolio at any time without shareholder approval.

Recent Market Conditions. An outbreak of respiratory disease caused by a novel coronavirus was first detected in China in late 2019 and subsequently spread 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. The impact of this coronavirus has resulted in a substantial economic downturn, which may continue for an extended period of time. Health crises caused by outbreaks of disease, such as the coronavirus outbreak, may exacerbate other pre-existing political, social and economic risks and disrupt normal market conditions and operations. The impact of this outbreak has negatively affected the worldwide economy, as well as the economies of individual countries and industries, and could continue to affect the market in significant and unforeseen ways. Other epidemics and pandemics that may arise in the future may have similar effects. For example, a global pandemic or other widespread health crisis could cause substantial market volatility and exchange trading suspensions and closures. In addition, the increasing interconnectedness of markets around the world may result in many markets being affected by events or conditions in a single country or region or events affecting a single or small number of issuers. The coronavirus outbreak and public and private sector responses thereto have led to large portions of the populations of many countries working from home for indefinite periods of time, temporary or permanent layoffs, disruptions in supply chains, and lack of availability of certain goods. The impact of such responses could adversely affect the information technology and operational systems upon which the Fund and the Fund’s service providers rely, and could otherwise disrupt the ability of the employees of the Fund’s service providers to

Eaton Vance Richard Bernstein Funds33Prospectus dated January 1, 2022

perform critical tasks relating to the Fund. Any such impact could adversely affect the Fund’s performance, or the performance of the securities in which the Fund invests and may lead to losses on your investment in the Fund.

General. The Equity Strategy Fund's 80% Policy will not be changed unless shareholders are given at least 60 days’ advance written notice of the change. Unless otherwise stated, the Fund's investment objective and certain other policies may be changed without shareholder approval. Shareholders will receive 60 days' advance written notice of any material change in the investment objective. The Fund might not use all of the strategies and techniques or invest in all of the types of securities described in this Prospectus or the SAI. While at times the Fund may use alternative investment strategies in an effort to limit its losses, it may choose not to do so.

The Fund’s annual operating expenses are expressed as a percentage of the Fund’s average daily net assets and may change as Fund assets increase and decrease over time. Purchase and redemption activities by Fund shareholders may impact the management of the Fund and its ability to achieve its investment objective. In addition, the redemption by one or more large shareholders or groups of shareholders of their holdings in the Fund could have an adverse impact on the remaining shareholders in the Fund. Mutual funds, investment advisers, other market participants and many securities markets are subject to rules and regulations and the jurisdiction of one or more regulators. Changes to applicable rules and regulations or to widely accepted market conventions or standards could have an adverse effect on securities markets and market participants, as well as on the Fund’s ability to execute its investment strategy. With the increased use of technologies by Fund service providers, such as the Internet, to conduct business, the Fund is susceptible to operational, information security and related risks. See “Additional Information about Investment Strategies and Risks” in the Fund’s SAI.

Management and Organization

Management. Each Fund’s investment adviser is Eaton Vance Management (“Eaton Vance”). Eaton Vance has offices at Two International Place, Boston, MA 02110. Eaton Vance and its predecessor organizations have been managing assets since 1924 and managing mutual funds since 1931. Prior to March 1, 2021, Eaton Vance was a wholly owned subsidiary of Eaton Vance Corp. (“EVC”).

On March 1, 2021, Morgan Stanley acquired EVC (the “Transaction”), and Eaton Vance became an indirect, wholly owned subsidiary of Morgan Stanley. In connection with the Transaction, each Fund entered into a new investment advisory and administrative agreement with its investment adviser and each Fund’s investment adviser entered into a new investment sub-advisory agreement with its sub-adviser. Each such agreement was approved by Fund shareholders prior to the consummation of the Transaction and was effective upon its closing.

Morgan Stanley (NYSE: MS), whose principal offices are at 1585 Broadway, New York, New York 10036, is a preeminent global financial services firm engaged in securities trading and brokerage activities, as well as providing investment banking, research and analysis, financing and financial advisory services. As of September 30, 2021, Morgan Stanley’s asset management operations had aggregate assets under management of approximately $1.5 trillion.

Pursuant to investment sub-advisory agreements, Eaton Vance has delegated the investment management of each Fund to Richard Bernstein Advisors LLC (“RBA”), a registered investment adviser. RBA is located at 1251 Avenue of the Americas, Suite 4102, New York, NY 10020. Eaton Vance pays RBA a portion of its fees for sub-advisory services provided to each Fund.

Each Fund’s annual shareholder report covering the fiscal period ended August 31 provides information regarding the basis for the Trustees’ approval of each Fund’s investment advisory and administrative agreement and each Fund’s investment sub-advisory agreement.

Eaton Vance Richard Bernstein Funds35Prospectus dated January 1, 2022

Eaton Vance provides sub-transfer agency and related services to Eaton Vance mutual funds pursuant to a Sub-Transfer Agency Support Services Agreement. For its services under the agreement, Eaton Vance receives an aggregate fee from such funds equal to its actual expenses incurred in performing such services.

Organization. Each Fund is a series of Eaton Vance Growth Trust, a Massachusetts business trust. Each Fund offers multiple classes of shares. Each Class represents a pro rata interest in a Fund but is subject to different expenses and rights. The Funds do not hold annual shareholder meetings but may hold special meetings for matters that require shareholder approval (such as electing or removing Trustees, approving management or advisory contracts or changing investment policies that may only be changed with shareholder approval).

Because the Funds use this combined Prospectus, a Fund could be held liable for a misstatement or omission made about another Fund.

Valuing Shares

Each Fund values its shares once each day only when the New York Stock Exchange (the “Exchange”) is open for trading (typically Monday through Friday), as of the close of regular trading on the Exchange (normally 4:00 p.m. Eastern Time). If trading on the Exchange is halted for the day before the scheduled close of regular trading, each Fund’s net asset value per share generally will still be calculated as of the scheduled close of regular trading on the Exchange. The purchase price of Fund shares is their net asset value (plus any applicable sales charge), which is derived from the value of Fund holdings. When purchasing or redeeming Fund shares through a financial intermediary, your financial intermediary must receive your order by the close of regular trading on the Exchange in order for the purchase price or the redemption price to be based on that day’s net asset value per share. It is the financial intermediary’s responsibility to transmit orders promptly. Each Fund may accept purchase and redemption orders as of the time of their receipt by certain financial intermediaries (or their designated intermediaries).

The Board has adopted procedures for valuing investments (the “Procedures”) and has delegated to the investment adviser(s) the daily valuation of such investments. Pursuant to the Procedures, securities and other investments held by a Fund are generally valued at market value. Exchange-listed investments (including certain derivatives) are normally valued at last sale or closing prices. Exchange-traded options are valued at the mean of the bid and asked prices at valuation time as reported by the Options Price Reporting Authority for U.S. listed options, or by the relevant exchange or board of trade for non-U.S. listed options. Non-exchange traded derivatives are normally valued on the basis of quotes obtained from brokers and dealers or independent pricing services. Most loans and other debt obligations are valued using prices supplied by one or more pricing services.

An instrument’s “fair value” is the amount that the owner might reasonably expect to receive for the instrument upon its current sale in the ordinary course of business. Under certain limited circumstances, a Fund may use fair value pricing if, for example, market prices or a pricing service's prices (as applicable) are unavailable or deemed unreliable, or if events occur after the close of a securities market (usually a foreign market) and before portfolio assets are valued that cause or are likely to cause a market quotation to be unavailable or unreliable, such as corporate actions, regulatory news, or natural disasters or governmental actions that may affect investments in a particular sector, country or region. In addition, for foreign equity securities and total return swaps and futures contracts on foreign indices that meet certain criteria, the Board has approved the use of a fair value service that values such investments to reflect market trading that occurs after the close of the applicable foreign markets of comparable securities or other investments that have a strong correlation to the fair valued investments. An investment that is fair valued may be valued at a price higher or lower than (i) actual market quotations, (ii) the value determined by other funds using their own fair valuation procedures, or (iii) the price at which the investment could have been sold during the period in which fair valuation was used with respect to such investment to calculate a Fund’s NAV. Because foreign investments held by a Fund, if any, may trade on days when Fund shares are not priced, the value of such investments, and thus the net asset value of a Fund’s shares, can change on days when Fund shares cannot be redeemed or purchased. Eaton Vance has established a Valuation Committee that oversees the valuation of investments.

Purchasing Shares

Set forth below is information about the manner in which each Fund offers shares. A financial intermediary may offer Fund shares subject to variations in or elimination of the Fund sales charges (“variations”), provided such variations are described in this Prospectus. All variations described in Appendix A are applied by, and the responsibility of, the identified financial intermediary. Sales charge variations may apply to purchases, sales, exchanges and reinvestments of Fund shares and a shareholder transacting in Fund shares through an intermediary identified on Appendix A should read the terms and conditions of Appendix A carefully. See also “Shareholder Account Features – ‘Street Name’ Accounts.” For the variations applicable to shares offered through certain financial intermediaries, please see Appendix A – Financial

Eaton Vance Richard Bernstein Funds36Prospectus dated January 1, 2022

Intermediary Sales Charge Variations. A variation that is specific to a particular financial intermediary is not applicable to shares held directly with a Fund or through another intermediary.

You may purchase shares through your financial intermediary or by mailing an account application form to the transfer agent (see back cover for address). Purchase orders will be executed at the net asset value (plus any applicable sales charge) next determined after their receipt in proper form (meaning that the order is complete and contains all necessary information) by a Fund’s transfer agent. A Fund’s transfer agent or your financial intermediary must receive your purchase in proper form no later than the close of regular trading on the Exchange (normally 4:00 p.m. Eastern Time) for your purchase to be effected at that day’s net asset value. If you purchase shares through a financial intermediary, that intermediary may charge you a fee for executing the purchase for you.

Each Fund may suspend the sale of its shares at any time and any purchase order may be refused for any reason. The U.S. registered funds sponsored by the Eaton Vance organization (the “Eaton Vance funds”) generally do not accept investments from residents of the European Union, the United Kingdom or Switzerland. The funds also do not accept investments from other non-U.S. residents, provided that a fund may accept investments from certain non-U.S. investors at the discretion of the principal underwriter. The Funds do not issue share certificates.

As used throughout this Prospectus, the term “employer sponsored retirement plan” includes the following: an employer sponsored pension or profit sharing plan that qualifies under section 401(a) of the Code (such as a 401(k) plan, money purchase pension, profit sharing and defined benefit plan); ERISA covered 403(b) plan; Taft-Hartley multi-employer plan; and non-qualified deferred compensation arrangements that operate in a similar manner to a qualified retirement plan (including 457 plans and executive deferred compensation arrangements). Individual Retirement Accounts (“IRAs”) are not employer sponsored retirement plans for purposes of this definition.

Eaton Vance Richard Bernstein Funds37Prospectus dated January 1, 2022

Class A and Class C Shares

Your initial investment must be at least $1,000. After your initial investment, additional investments may be made in any amount at any time by sending a check payable to the order of the Fund or the transfer agent directly to the transfer agent (see back cover for address). Please include your name and account number and the name of the Fund and Class of shares with each investment. Each Fund no longer accepts direct purchases of Class C shares by accounts for which no broker-dealer or other financial intermediary is specified. Any direct purchase received by a Fund's transfer agent for Class C shares for such accounts will automatically be invested in Class A shares.

The minimum initial investment amount and Fund policy of redeeming accounts with low account balances are waived for bank automated investing accounts, certain group purchase plans (including employer sponsored retirement plans and proprietary fee-based programs sponsored by financial intermediaries) and for persons affiliated with Eaton Vance, its affiliates and certain Fund service providers (as described in the SAI).

Class I Shares

Your initial investment must be at least $250,000, except as noted below. Class I shares are offered to clients of financial intermediaries who (i) charge such clients an ongoing fee for advisory, investment, consulting or similar services, or (ii) have entered into an agreement with the principal underwriter to offer Class I shares through a no-load network or platform. Such clients may include individuals, corporations, endowments, foundations and employer sponsored retirement plans. Class I shares may also be available through brokerage platforms of broker-dealer firms that have agreements with a Fund’s principal underwriter to offer Class I shares solely when acting as an agent for the investor. An investor acquiring Class I shares through such platforms may be required to pay a commission and/or other forms of compensation to the broker. Each Fund offers other share classes that have different fees and expenses. Class I shares also are offered to investment and institutional clients of Eaton Vance and its affiliates and certain persons affiliated with Eaton Vance.

The Class I minimum initial investment is waived for persons affiliated with Eaton Vance, its affiliates and certain Fund service providers (as described in the SAI). The minimum initial investment also is waived for: (i) permitted exchanges; (ii) employer sponsored retirement plans; (iii) corporations, endowments and foundations with assets of at least $100 million; (iv) Class I shares purchased through the brokerage platforms described above; and (v) accounts of clients of financial intermediaries who (a) charge an ongoing fee for advisory, investment, consulting or similar services, or (b) have entered into an agreement with the principal underwriter to offer Class I shares through a no-load network or platform (in each case, as described above).

Class I shares may be purchased through a financial intermediary or by requesting your bank to transmit immediately available funds (Federal Funds) by wire. To make an initial investment by wire, you must complete an account application and telephone Eaton Vance Shareholder Services at 1-800-262-1122 to be assigned an account number. You may request an account application by calling 1-800-262-1122 Monday through Friday, 8:30 a.m. to 5:30 p.m. (Eastern Time). Shareholder Services must be advised by telephone of each additional investment by wire.

Subsequent Investments. Subsequent investments of any amount may be made at any time, including through automatic investment each month or quarter from your bank account. You may make automatic investments of $50 or more each month or each quarter from your bank account provided such investments equal a minimum of $200 per year. You can establish bank automated investing on the account application or by providing written instructions to the Fund’s transfer agent. Please call 1-800-262-1122 Monday through Friday, 8:30 a.m. to 5:30 p.m. (Eastern Time) for further information.

You also may make additional investments by accessing your account via the Eaton Vance website at www.eatonvance.com. The trade date of purchases made through the Internet from a pre-designated bank account will be the day the purchase is requested through the Eaton Vance website (provided the request is on a business day and submitted no later than the close of regular trading on the Exchange). For more information about purchasing shares through the Internet, please call 1-800-262-1122 Monday through Friday, 8:30 a.m. to 5:30 p.m. (Eastern Time).

Inactive Accounts. In accordance with state “unclaimed property” (also known as “escheatment”) laws, your Fund shares may legally be considered abandoned and required to be transferred to the relevant state if no account activity or contact with the Fund or your financial intermediary occurs within a specified period of time. Please initiate contact a least once per calendar year and maintain a current and valid mailing address on record for your account. For more information, please see https://funds.eatonvance.com/mutual-funds-and-abandoned-property.php or please contact us at 1-800-262-1122.

Eaton Vance Richard Bernstein Funds38Prospectus dated January 1, 2022

Restrictions on Excessive Trading and Market Timing. The Funds are not intended for excessive trading or market timing. Market timers seek to profit by rapidly switching money into a fund when they expect the share price of the fund to rise and taking money out of the fund when they expect those prices to fall. By realizing profits through short-term trading, shareholders that engage in rapid purchases and sales (including exchanges, if permitted) of a fund’s shares may dilute the value of shares held by long-term shareholders. Volatility resulting from excessive purchases and sales of fund shares, especially involving large dollar amounts, may disrupt efficient portfolio management. In particular, excessive purchases and sales of a fund’s shares may cause a fund to have difficulty implementing its investment strategies, may force the fund to sell portfolio securities at inopportune times to raise cash or may cause increased expenses (such as increased brokerage costs, realization of taxable capital gains without attaining any investment advantage or increased administrative costs).

A fund that invests all or a portion of its assets in foreign securities may be susceptible to a time zone arbitrage strategy in which shareholders attempt to take advantage of fund share prices that may not reflect developments in a foreign securities market that occur after the close of such market but prior to the pricing of fund shares. In addition, a fund that invests in securities that are, among other things, thinly traded, traded infrequently or illiquid, is susceptible to the risk that the current market price for such securities may not accurately reflect current market values. A shareholder may seek to engage in short-term trading to take advantage of these pricing differences (commonly referred to as “price arbitrage”). The investment adviser(s) and sub-adviser(s) are authorized to use the fair value of a security if prices are unavailable or are deemed unreliable (see “Valuing Shares”). The use of fair value pricing and the restrictions on excessive trading and market timing described below are intended to reduce a shareholder’s ability to engage in price or time zone arbitrage to the detriment of the Funds.

The Boards of the Eaton Vance funds have adopted policies to discourage short-term trading and market timing and to seek to minimize their potentially detrimental effects (the “Policy”). Under the Policy, the Board has delegated to Eaton Vance the responsibility to reject or cancel a purchase order, suspend or terminate an exchange privilege or terminate the ability of a shareholder to invest in the Eaton Vance funds if Eaton Vance determines that a proposed transaction involves market timing or excessive trading that it believes is likely to be detrimental to a Fund.

Pursuant to the Policy, two “round-trips” completed by a Fund shareholder within 90 days through one or more accounts (the “Limitation”) generally will be deemed to be indicative of market timing or trading excessively in fund shares. A “round trip” is defined as a purchase or exchange into a Fund followed or preceded by a redemption or exchange out of the Fund. Purchases and redemptions subject to the Limitation include those made by exchanging to or from another fund. Eaton Vance will evaluate transactions in Fund shares that violate the Limitation to determine whether they are likely to be detrimental to the Fund. In making such a determination, Eaton Vance may consider various factors, such as the amount, frequency and nature of trading activity. If such a determination is made, a Fund shareholder may be subject to restrictions on trading Fund shares, as described above. Eaton Vance uses reasonable efforts to detect market timing and excessive trading activity that is likely to be detrimental to a Fund, but it cannot ensure that it will be able to identify all such cases. Eaton Vance may also reject or cancel any purchase order (including an exchange) from a shareholder or group of shareholders for any other reason. In applying the Policy, and in particular when determining whether a transaction is likely to be detrimental to a Fund, Eaton Vance will be required to make judgments that are inherently subjective and will depend on the specific facts and circumstances. Such determinations will be made in a manner believed to be in the best interest of a Fund’s shareholders. No Eaton Vance fund has any arrangement to permit market timing.

The following fund share transactions generally are exempt from the Policy because they generally do not raise market timing or excessive trading concerns:

·transactions (i) made pursuant to a Fund’s systematic purchase, exchange or redemption plan, (ii) made as the result of automatic reinvestment of dividends or distributions, or (iii) initiated by a Fund (e.g., for transactions due to a failure to meet applicable account minimums);

·transactions made by participants in employer sponsored retirement plans involving (i) participant payroll or employer contributions or loan repayments, (ii) redemptions as part of plan terminations or at the direction of the plan, mandatory retirement distributions, or (iii) rollovers;

·transactions in shares of Eaton Vance Short Duration Government Income Fund; or

·investments in a fund by ReFlow in connection with the ReFlow liquidity program (if applicable to a Fund, the ReFlow liquidity program is described under “Investment Objectives & Principal Policies and Risks” above).

The following Fund share transactions generally are exempt from the Limitation; however, these transactions are subject to monitoring by Eaton Vance and may be subject to restrictions if deemed likely to be detrimental to a Fund:

·transactions made by model-based discretionary advisory accounts; or

Eaton Vance Richard Bernstein Funds39Prospectus dated January 1, 2022

·transactions made by funds that invest in a Fund as part of an asset reallocation in accordance with their investment policies or in response to Fund inflows and outflows.

It may be difficult for Eaton Vance to identify market timing or excessive trading in omnibus accounts traded through financial intermediaries. Eaton Vance has provided guidance to financial intermediaries (such as banks, broker-dealers, insurance companies and retirement administrators) concerning the application of the Policy to Fund shares held in omnibus accounts maintained and administered by such intermediaries, including guidance concerning situations where market timing or excessive trading is considered to be detrimental to a Fund. Eaton Vance may rely on a financial intermediary’s policy to restrict market timing and excessive trading if it believes that policy is likely to prevent market timing that is likely to be detrimental to the Fund. Such policy may be more or less restrictive than the Policy. Although Eaton Vance reviews trading activity at the omnibus account level for activity that indicates potential market timing or excessive trading activity, Eaton Vance typically will not request or receive individual account data unless suspicious trading activity is identified. Eaton Vance generally relies on financial intermediaries to monitor trading activity in omnibus accounts in good faith in accordance with their own policies or the Policy. Eaton Vance cannot ensure that these financial intermediaries will in all cases apply the Policy or their own policies, as the case may be, to accounts under their control.

Choosing a Share Class. Each Fund offers different classes of shares. The different classes of shares represent investments in the same portfolio of securities, but the classes are subject to different expenses and privileges, and will likely have different share prices due to differences in class expenses. A share class also may be subject to a sales charge. In choosing the class of shares that suits your investment needs, you should consider:

·how long you expect to own your shares;

·how much you intend to invest; and

·the total operating expenses associated with owning each class.

Each investor’s considerations are different. You should speak with your financial intermediary to help you decide which class of shares to purchase. Set forth below is a brief description of each class of shares offered by the Funds.

Class A shares are offered at net asset value plus a front-end sales charge of up to 5.75%. This charge is deducted from the amount you invest. The Class A sales charge is reduced for purchases of $50,000 or more. The sales charge applicable to your purchase may be reduced under the right of accumulation or a statement of intention, which are described in “Reducing or Eliminating Class A Sales Charges” under “Sales Charges” below. Some investors may be eligible to purchase Class A shares at net asset value under certain circumstances, which are also described below. Class A shares pay distribution and service fees equal to 0.25% annually of average daily net assets.

Class C shares are offered through financial intermediaries at net asset value with no front-end sales charge. If you sell your Class C shares within 12 months of purchase, you generally will be subject to a contingent deferred sales charge or “CDSC.” The CDSC is deducted from your redemption proceeds. Under certain circumstances, the CDSC for Class C may be waived (such as certain redemptions from employer sponsored retirement plans). See “CDSC Waivers” under “Sales Charges” below. Class C shares pay distribution and service fees equal to 1.00% annually of average daily net assets. Orders for Class C shares of one or more Eaton Vance funds will be refused when the total value of the purchase (including the aggregate market value of all Eaton Vance fund shares held within the purchasing shareholder’s account(s)) is $1 million or more. Investors considering cumulative purchases of $1 million or more should consider whether another Class of shares would be more appropriate and consult their financial intermediary. Each Fund no longer accepts direct purchases of Class C shares by accounts for which no broker-dealer or other financial intermediary is specified. Any direct purchase received by a Fund’s transfer agent for Class C shares for such accounts will automatically be invested in Class A shares. In addition, Class C shares held in an account for which no financial intermediary is specified and which are not subject to a CDSC will periodically be converted to Class A shares.

Class I shares are offered to clients of financial intermediaries who (i) charge such clients an ongoing fee for advisory, investment, consulting or similar services, or (ii) have entered into an agreement with the principal underwriter to offer Class I shares through a no-load network or platform. Such clients may include individuals, corporations, endowments, foundations and employer sponsored retirement plans. Class I shares may also be available through brokerage platforms of broker-dealer firms that have agreements with the Fund’s principal underwriter to offer Class I shares solely when acting as an agent for the investor. An investor acquiring Class I shares through such platforms may be required to pay a commission and/or other forms of compensation to the broker. Class I shares are also offered to investment and institutional clients of Eaton Vance and its affiliates, and certain persons affiliated with Eaton Vance (including employees, officers and directors of Eaton Vance’s affiliates). Class I shares do not pay distribution or service fees.

Eaton Vance Richard Bernstein Funds40Prospectus dated January 1, 2022

Payments to Financial Intermediaries. In addition to payments disclosed under “Sales Charges” below, the principal underwriter, out of its own resources, may make cash payments to certain financial intermediaries (which may include affiliates of the principal underwriter and investment adviser) who provide marketing support, transaction processing and/or administrative services and, in some cases, include some or all Eaton Vance funds in preferred or specialized selling programs. Payments made by the principal underwriter to a financial intermediary may be significant and are typically in the form of fees based on Fund sales, assets, transactions processed and/or accounts attributable to that financial intermediary. Financial intermediaries also may receive amounts from the principal underwriter in connection with educational or due diligence meetings that include information concerning Eaton Vance funds. The principal underwriter may pay or allow other promotional incentives or payments to financial intermediaries to the extent permitted by applicable laws and regulations.

Certain financial intermediaries that maintain fund accounts for the benefit of their customers provide sub-accounting, recordkeeping and/or administrative services to the Eaton Vance funds and are compensated for such services by the funds. As used in this Prospectus, the term “financial intermediary” includes any broker, dealer, bank (including bank trust departments), registered investment adviser, financial planner, a retirement plan and/or its administrator, their designated intermediaries and any other firm having a selling, administration or similar agreement with the principal underwriter or its affiliates.

Sales Charges

Class A Front-End Sales Charge. Class A shares are offered at net asset value per share plus a sales charge that is determined by the amount of your investment. The current sales charge schedule is:

Amount of Purchase	Sales Charge* as a Percentage of Offering Price	Sales Charge* as a Percentage of Net Amount Invested	Dealer Commission as a Percentage of Offering Price
Less than $50,000	5.75%	6.10%	5.00%
$50,000 but less than $100,000	4.75%	4.99%	4.00%
$100,000 but less than $250,000	3.75%	3.90%	3.00%
$250,000 but less than $500,000	3.00%	3.09%	2.50%
$500,000 but less than $1,000,000	2.00%	2.04%	1.75%
$1,000,000 but less than $3,000,000	0.00**	0.00**	TIERED**
$3,000,000 or more	0.00**	0.00**	TIERED**

*Because the offering price per share is rounded to two decimal places, the actual sales charge you pay on a purchase of Class A shares may be more or less than your total purchase amount multiplied by the applicable sales charge percentage.

**No sales charge is payable at the time of purchase on investments of $1 million or more. The principal underwriter will pay a commission to financial intermediaries on sales of $1 million or more as follows: 1.00% on amounts of $1 million or more but less than $3 million; plus 0.75% on amounts of $3 million or more. A CDSC of 1.00% will be imposed on such investments (as described below) in the event of redemptions within 18 months of purchase.

Reducing or Eliminating Class A Sales Charges. Front-end sales charges on purchases of Class A shares may be reduced under the right of accumulation or under a statement of intention. To receive a reduced sales charge, you must inform your financial intermediary or a Fund at the time you purchase shares that you qualify for such a reduction. If you do not let your financial intermediary or the Fund know you are eligible for a reduced sales charge at the time of purchase, you will not receive the discount to which you may otherwise be entitled.

Right of Accumulation. Under the right of accumulation, the sales charge you pay is reduced if the current market value of your holdings in a Fund or any other Eaton Vance fund (based on the current maximum public offering price) plus your new purchase total $50,000 or more. Shares owned by you, your spouse and children under age twenty-one may be combined for purposes of the right of accumulation, including shares held for the benefit of any of you in omnibus or “street name” accounts. In addition, shares held in a trust or fiduciary account of which any of the foregoing persons is the sole beneficiary (including employer sponsored retirement plans and IRAs) may be combined for purposes of the right of accumulation. Shares purchased and/or owned in a SEP, SARSEP and SIMPLE IRA plan may be combined for purposes of the right of accumulation for the plan and its participants. You may be required to provide documentation to establish your ownership of shares included under the right of accumulation (such as account statements for you, your spouse and children or marriage certificates, birth certificates and/or trust or other fiduciary-related documents).

Eaton Vance Richard Bernstein Funds41Prospectus dated January 1, 2022

Statement of Intention. Under a statement of intention, purchases of $50,000 or more made over a 13-month period are eligible for reduced sales charges. Shares eligible under the right of accumulation (other than those included in employer sponsored retirement plans) may be included to satisfy the amount to be purchased under a statement of intention. Under a statement of intention, the principal underwriter may hold 5% of the dollar amount to be purchased in escrow in the form of shares registered in your name until you satisfy the statement or the 13-month period expires. A statement of intention does not obligate you to purchase (or a Fund to sell) the full amount indicated in the statement. If during the 13-month period you redeem any of the shares that you purchased pursuant to the statement of intention, the value of the redeemed shares will not be included for purposes of satisfying your statement of intention. For additional information about statements of intention, see “Sales Charges” in the SAI.

Class A shares are offered at net asset value (without a sales charge) to accounts of clients of financial intermediaries who (i) charge an ongoing fee for advisory, investment, consulting or similar services, or (ii) have entered into an agreement with the principal underwriter to offer Class A shares through a no-load network or platform, or self-directed brokerage accounts that may or may not charge transaction fees to customers; or (iii) employer sponsored retirement plans. Class A shares also are offered at net asset value to investment and institutional clients of Eaton Vance and its affiliates; certain persons affiliated with Eaton Vance; direct purchases of shares by accounts where no financial intermediary is specified; and to certain fund service providers as described in the SAI. Class A shares are also offered at net asset value to shareholders who make a permitted direct transfer or roll-over to an Eaton Vance prototype IRA from an employer-sponsored retirement plan previously invested in Eaton Vance funds (applicable only to the portion previously invested in Eaton Vance funds), provided that sufficient documentation is provided to the transfer agent of such transfer or roll-over at the time of the account opening. Class A shares may also be purchased at net asset value pursuant to the exchange privilege and when distributions are reinvested. A financial intermediary may not, in accordance with its policies and procedures, offer one or more of the waiver categories described above and shareholders should consult their financial intermediary for more information. The Fund may eliminate, modify or add to the terms of these sales charge waivers at any time without providing notice to shareholders.

Contingent Deferred Sales Charge. Class A and Class C shares are subject to a CDSC on certain redemptions. The CDSC generally is paid to the principal underwriter. Class A shares purchased at net asset value in amounts of $1 million or more are subject to a 1.00% CDSC if redeemed within 18 months of purchase. Class C shares are subject to a 1.00% CDSC if redeemed within 12 months of purchase. CDSCs are based on the lower of the net asset value at the time of purchase or at the time of redemption. Shares acquired through the reinvestment of distributions are exempt from the CDSC. Redemptions are made first from shares that are not subject to a CDSC.

The sales commission payable to financial intermediaries in connection with sales of Class C shares is described under “Distribution and Service Fees” below.

CDSC Waivers. CDSCs are waived for certain redemptions pursuant to a Withdrawal Plan (see “Shareholder Account Features”) and in connection with certain redemptions from employer sponsored retirement plans or IRAs to satisfy required minimum distributions or to return excess contributions made to IRAs, if applicable. The CDSC is also waived following the death of a beneficial owner of shares (a death certificate and other applicable documents may be required). In addition, redemptions of Class C shares by certain employer sponsored retirement plans are not subject to a CDSC if the principal underwriter did not compensate such plans’ financial intermediary at the time of sale as described under “Distribution and Service Fees.”

Conversion Feature. Effective November 5, 2020 (the “Effective Date”), Class C shares of a Fund will convert automatically to Class A shares of the Fund during the month following the eight year anniversary of the purchase of such Class C shares. If a financial intermediary that maintains a Class C shareholder’s account has not tracked the holding period for Class C shares, Class C shares held as of the Effective Date will automatically convert to Class A shares eight years after the Effective Date. In addition, Class C shares held in an account with each Fund’s transfer agent for which no financial intermediary is specified and that are not subject to a CDSC will be converted to Class A shares of the Fund periodically.

In some circumstances, the Board may determine to cease to offer and subsequently close an existing class of Fund shares. In such circumstances, the Fund may automatically convert the shares for such class into another share class, subject to prior notice to shareholders of the impacted class. Any such conversion will occur at the respective net asset value of each class as of the conversion date without the imposition of any fee or other charges by the Fund.

Distribution and Service Fees. Class A and Class C shares have in effect plans under Rule 12b-1 that allow each Fund to pay distribution fees for the sale and distribution of shares and service fees for personal and/or shareholder account services (so-called “12b-1 fees”). Class C shares pay distribution fees to the principal underwriter of 0.75% of average daily net assets annually. Because these fees are paid from Fund assets on an ongoing basis, they will increase your cost over time and may cost you more than paying other types of sales charges. The principal underwriter generally

Eaton Vance Richard Bernstein Funds42Prospectus dated January 1, 2022

compensates financial intermediaries on sales of Class C shares (except exchange transactions and reinvestments) in an amount equal to 1% of the purchase price of the shares. After the first year, such financial intermediaries also receive 0.75% of the value of outstanding Class C shares sold by such financial intermediaries in annual distribution fees. With respect to purchases of Class C shares by certain employer sponsored retirement plans, the principal underwriter does not compensate the financial intermediary at the time of sale. In such cases, the financial intermediary receives 0.75% of the value of outstanding Class C shares sold by such financial intermediary in annual distribution fees immediately after the sale. Class C shares also pay service fees to the principal underwriter equal to 0.25% of average daily net assets annually. Class A shares pay distribution and service fees equal to 0.25% of average daily net assets annually. After the sale of shares, the principal underwriter generally receives the Class A distribution and service fees and the Class C service fees for one year. Thereafter financial intermediaries generally receive from the principal underwriter 0.25% annually of average daily net assets based on the value of outstanding shares sold by such financial intermediaries for shareholder servicing performed by such intermediaries. With respect to purchases of Class A and Class C shares by certain employer sponsored retirement plans, the financial intermediary receives the above described distribution and service fees or service fees, as applicable, from the principal underwriter immediately after the sale. Distribution and service fees are subject to the limitations contained in the sales charge rule of the Financial Industry Regulatory Authority, Inc.

More information about Fund sales charges is available free of charge on the Eaton Vance website at www.eatonvance.com and in the SAI. Please consult the Eaton Vance website for any updates to Fund sales charge information before making a purchase of Fund shares. Please consult your financial intermediary with respect to any sales charge variations listed on Appendix A.

Redeeming Shares

You can redeem shares in any of the following ways:

By Mail	Send your request to the transfer agent (see back cover for address). The request must be signed exactly as your account is registered (for instance, a joint account must be signed by all registered owners to be accepted) and a Medallion signature guarantee may be required. Circumstances that may require a Medallion signature guarantee include, but are not limited to, requests to distribute redemption proceeds to a party other than the registered account owner(s); requests to mail redemption proceeds to an address other than the address of record; requests to distribute proceeds to a bank account not on file; requests to re-issue uncashed checks representing redemption proceeds; or transaction requests from an account beneficiary when an account owner is deceased. You can obtain a Medallion signature guarantee at banks, savings and loan institutions, credit unions, securities dealers, securities exchanges, clearing agencies and registered securities associations that participate in The Securities Transfer Agents Medallion Program, Inc. (STAMP, Inc.). Only Medallion signature guarantees issued in accordance with STAMP, Inc. will be accepted. You may be asked to provide additional documents if your shares are registered in the name of a corporation, partnership or fiduciary.
By Telephone	Certain shareholders can redeem by calling 1-800-262-1122 Monday through Friday, 8:30 a.m. to 5:30 p.m. (Eastern Time). Proceeds of a telephone redemption are generally limited to $100,000 per account (which may include shares of one or more Eaton Vance funds) and can be sent only to the account address or to a bank pursuant to prior instructions.
By Internet	Certain shareholders can redeem by logging on to the Eaton Vance website at www.eatonvance.com. Proceeds of internet redemptions are generally limited to $100,000 per account (which may include shares of one or more Eaton Vance funds) and can be sent only to the account address or to a bank pursuant to prior instructions.
For Additional Information	Please call 1-800-262-1122 Monday through Friday, 8:30 a.m. to 5:30 p.m. (Eastern Time).
Through a Financial Intermediary	Your financial intermediary is responsible for transmitting the order promptly. A financial intermediary may charge a fee for this service.

A redemption may be requested by sending a Medallion signature guaranteed letter of instruction to the transfer agent (see back cover for address) or, for telephone redemptions as described above, by calling 1-800-262-1122. Certain redemption requests, including those involving shares held by certain corporations, trusts or certain other entities and shares that are subject to certain fiduciary arrangements, may require additional documentation and may be redeemed only by mail. The Funds' transfer agent or your financial intermediary must receive your redemption in proper form (meaning that it is complete and contains all necessary information) no later than the close of regular trading on the Exchange (normally 4:00 p.m. Eastern Time) for your redemption to be effected at that day’s net asset value. Redemption proceeds are reduced by the amount of any applicable CDSC and any federal income and state tax required to be withheld.

Redemption proceeds typically are paid to the redeeming shareholder in cash up to two business days after the redemption, but payment could take up to seven days, as permitted by the 1940 Act for the reasons discussed below. The actual number of days following receipt of a redemption request in which the Fund typically expects to pay redemption proceeds generally will depend on how you hold your shares with the Fund.

If your shares are held in a “street name” account with a financial intermediary (see “Shareholder Account Features – ‘Street Name’ Accounts”), your intermediary will elect through National Securities Clearing Corporation (“NSCC”) to settle redemptions either one business day or two business days after the redemption date and redemption proceeds normally will be wired to your financial intermediary on the settlement date pursuant to that election.

Eaton Vance Richard Bernstein Funds44Prospectus dated January 1, 2022

If your shares are held directly with the Funds' transfer agent, redemptions normally will be settled in one business day after the redemption date and redemption proceeds will be sent by regular mail on such date. However, if you have given proper written authorization in advance, you may request that redemption proceeds be wired on the settlement date directly to your bank account in any bank in the United States. While not currently charged by a Fund, you may be required to pay a wire transfer fee by your bank. If you request expedited mail delivery of your redemption proceeds and the Fund is able to accommodate your request, charges may apply. You may redeem all or a portion of the shares from your account on any day the Fund is open for business, provided the amount requested is not on hold or held in escrow pursuant to a statement of intention. When you purchase by check or with ACH funds transfer, the purchase will be on hold for up to 10 days from the date of receipt. During the hold period, redemption proceeds will not be sent until the transfer agent is reasonably satisfied that the purchase payment has been collected.

Each Fund typically expects to meet redemption requests by (i) distributing any cash holdings, (ii) selling portfolio investments and/or (iii) borrowing from a bank under a line of credit. In addition to the foregoing, the Fund also may distribute securities as payment (a so-called “redemption in-kind”), in which case the redeeming shareholder may pay fees and commissions to convert the securities to cash. Unless requested by a shareholder, each Fund generally expects to limit use of redemption in-kind to stressed market conditions, but is permitted to do so in other circumstances. A shareholder who wishes to receive redemption proceeds in-kind must notify a Fund on or before submitting the redemption request by calling 1-800-262-1122. Securities distributed in a redemption in-kind would be valued pursuant to each Fund’s valuation procedures and selected by the investment adviser. If a shareholder receives securities in a redemption in-kind, the shareholder could incur brokerage or other charges in converting the securities to cash and the value of such securities would be subject to price fluctuations until sold. There can be no assurance that each Fund will manage liquidity successfully in all market environments. As a result, a Fund may not be able to pay redemption proceeds in a timely fashion because of unusual market conditions, an unusually high volume of redemption requests or other factors. Additional information about redemptions in-kind, including the procedures for submitting such redemption requests, is contained in each Fund’s SAI.

If your account value falls below $750, you may be asked either to add to your account or redeem it within 60 days. If you take no action, your account will be redeemed at net asset value and the proceeds sent to you.

Shareholder Account Features

Distributions. You may have your Fund distributions paid in one of the following ways:

• Full Reinvest Option	Distributions are reinvested in additional shares. This option will be assigned if you do not specify an option.
• Partial Reinvest Option	Dividends are paid in cash* and capital gains are reinvested in additional shares.
• Cash Option	Distributions are paid in cash.*
• Exchange Option	Distributions are reinvested in additional shares of any class of another Eaton Vance fund chosen by you, subject to the terms of that fund’s prospectus. Before selecting this option, you must obtain a prospectus of the other fund and consider its objectives, risks, and charges and expenses carefully.

*If any distribution check remains uncashed for six months, Eaton Vance reserves the right to invest the amount represented by the check in Fund shares at the then-current net asset value of the Fund and all future distributions will be reinvested.

Information about the Funds. From time to time, you may receive the following:

·Semiannual and annual reports containing a list of portfolio holdings as of the end of the second and fourth fiscal quarters, respectively, performance information and financial statements.

·Periodic account statements, showing recent activity and total share balance.

·Tax information needed to prepare your income tax returns.

·Proxy materials, in the event a shareholder vote is required.

·Special notices about significant events affecting your Fund.

Most fund information (including semiannual and annual reports, prospectuses and proxy statements) as well as your periodic account statements can be delivered electronically. For more information please go to www.eatonvance.com/edelivery.

Eaton Vance Richard Bernstein Funds45Prospectus dated January 1, 2022

You may be contacted via mail, telephone or by electronic means by officers of a Fund, by personnel of the investment adviser or administrator, by the Fund’s transfer agent, by broker-dealer firms, or by a professional solicitation organization in connection with a solicitation of proxies for a meeting of Fund shareholders.

The Eaton Vance funds have established policies and procedures with respect to the disclosure of portfolio holdings and other information concerning Fund characteristics. A description of these policies and procedures is provided below and additionally in the SAI. Such policies and procedures regarding disclosure of portfolio holdings are designed to prevent the misuse of material, non-public information about the funds.

Each Fund will file information regarding its portfolio holdings with the SEC on its Form N-PORT. Each Fund’s annual and semiannual reports (as filed on Form N-CSR) and certain information filed on Form N-PORT may be viewed on the SEC’s website (www.sec.gov). The most recent fiscal quarter-end holdings may also be viewed on the Eaton Vance website (www.eatonvance.com). Portfolio holdings information that is filed with the SEC is posted on the Eaton Vance website approximately 60 days after the end of the quarter to which it relates. Portfolio holdings information as of each month end is posted to the website approximately one month after such month end. Each Fund also posts information about certain portfolio characteristics (such as top ten holdings and asset allocation) at least quarterly on the Eaton Vance website approximately ten business days after the period and each Fund may also post performance attribution as of a month end or more frequently if deemed appropriate.

Withdrawal Plan. You may redeem shares on a regular periodic basis by establishing a systematic withdrawal plan. Withdrawals will not be subject to any applicable CDSC if they are, in the aggregate, less than or equal to 12% annually of the greater of either the initial account balance or the current account balance. Because purchases of Class A shares are generally subject to an initial sales charge, Class A shareholders should not make withdrawals from their accounts while also making purchases.

Exchange Privilege. Each class of Fund shares may be exchanged for shares of the same Class of another Eaton Vance fund. For purposes of exchanges among Eaton Vance funds, Class A and Class I shares are deemed to be the same as Investor Class and Institutional Class shares, respectively, of other Eaton Vance funds. Exchanges are made at net asset value. If your shares are subject to a CDSC, the CDSC will continue to apply to your new shares at the same CDSC rate. For purposes of the CDSC, your shares will continue to age from the date of your original purchase of Fund shares. Except as described below, any class of shares of a fund may be exchanged for any other class of shares of that fund, provided that the shares being exchanged are no longer subject to a CDSC and the conditions for investing in the other class of shares described in the applicable prospectus are satisfied. Class C shares are not permitted to be exchanged to Class A shares unless the CDSC has expired and the exchange is made to facilitate the shareholder's participation in a fee-based advisory program. See also Appendix A to this Prospectus.

Before exchanging, you should read the prospectus of the new fund carefully. Exchanges are subject to the terms applicable to purchases of the new fund’s shares as set forth in its prospectus. If you wish to exchange shares, write to the transfer agent (see back cover for address), log on to your account at www.eatonvance.com or call 1-800-262-1122. Periodic automatic exchanges are also available. The exchange privilege may be changed or discontinued at any time. You will receive at least 60 days’ notice of any material change to the privilege. This privilege may not be used for “market timing” and may be terminated for market timing accounts or for any other reason. For additional information, see “Restrictions on Excessive Trading and Market Timing” under “Purchasing Shares.” Ordinarily exchanges between different funds are taxable transactions for federal tax purposes, while permitted exchanges of one class for shares of another class of the same fund are not. Shareholders should consult their tax advisors regarding the applicability of federal, state, local and other taxes to transactions in Fund shares.

Reinvestment Privilege. If you redeem shares, you may reinvest at net asset value all or any portion of the redemption proceeds in the same account and in the same class of shares of the Fund you redeemed from or another Fund, provided that the reinvestment occurs within 90 days of the redemption, the privilege has not been used more than once in the prior 12 months, the redeemed shares were subject to a front-end sales charge or CDSC and that you are otherwise eligible to invest in that class. Under these circumstances your account will be credited with any CDSC paid in connection with the redemption. Any CDSC period applicable to the shares you acquire upon reinvestment will run from the date of your original share purchase. For requests for reinvestment sent to the Fund's transfer agent, the request must be in writing. At the time of a reinvestment, you or your financial intermediary must notify the Fund or the transfer agent that you are reinvesting redemption proceeds in accordance with this privilege. If you reinvest, your purchase will be at the next determined net asset value following receipt of your request.

Eaton Vance Richard Bernstein Funds46Prospectus dated January 1, 2022

follow reasonable procedures, they will not be responsible for unauthorized telephone or electronic transactions and you bear the risk of possible loss resulting from these transactions. You may decline the telephone redemption option on the account application. Telephone instructions are recorded. You should verify the accuracy of your confirmation statements immediately upon receipt and notify Eaton Vance Shareholder Services of any inaccuracies.

“Street Name” Accounts. If your shares are held in a “street name” account at a financial intermediary, that intermediary (and not the Fund or its transfer agent) will perform all recordkeeping, transaction processing and distribution payments. Because the Fund does not maintain an account for you, you should contact your financial intermediary to make transactions in shares, make changes in your account, or obtain account information. You will not be able to utilize a number of shareholder features, such as telephone or internet transactions, directly with a Fund and certain features may be subject to different requirements. If you transfer shares in a “street name” account to an account with another financial intermediary or to an account directly with a Fund, you should obtain historical information about your shares prior to the transfer. If you fail to provide your full account history to your new financial intermediary following a transfer, you may be ineligible for certain features of a Fund.

Procedures for Opening New Accounts. To help the government fight the funding of terrorism and money laundering activities, federal law requires financial institutions to obtain, verify and record information that identifies each new customer who opens an account with a Fund and to determine whether such person’s name appears on government lists of known or suspected terrorists or terrorist organizations. When you open an account, the transfer agent or your financial intermediary will ask you for your name, address, date of birth (for individuals), residential or business street address (although post office boxes are still permitted for mailing) and social security number, taxpayer identification number, or other government-issued identifying number. You also may be asked to produce a copy of your driver’s license, passport or other identifying documents in order to verify your identity. In addition, it may be necessary to verify your identity by cross-referencing your identification information with a consumer report or other electronic databases. Other information or documents may be required to open accounts for corporations and other entities. Federal law prohibits a Fund and other financial institutions from opening a new account unless they receive the minimum identifying information described above. If a person fails to provide the information requested, any application by that person to open a new account will be rejected. Moreover, if the transfer agent or the financial intermediary is unable to verify the identity of a person based on information provided by that person, it may take additional steps including, but not limited to, requesting additional information or documents from the person, closing the person’s account or reporting the matter to the appropriate federal authorities. If your account is closed for this reason, your shares may be automatically redeemed at the net asset value next determined. If a Fund’s net asset value has decreased since your purchase, you will lose money as a result of this redemption. Each Fund has also designated an anti-money laundering compliance officer.

Account Questions. If you have any questions about your account or the services available, please call Eaton Vance Shareholder Services at 1-800-262-1122 Monday through Friday, 8:30 a.m. to 5:30 p.m. (Eastern Time), or write to the transfer agent (see back cover for address).

Potential Conflicts of Interest

As a diversified global financial services firm, Morgan Stanley, the parent company of the investment adviser, engages in a broad spectrum of activities, including financial advisory services, investment management activities, lending, commercial banking, sponsoring and managing private investment funds, engaging in broker-dealer transactions and principal securities, commodities and foreign exchange transactions, research publication and other activities. In the ordinary course of its business, Morgan Stanley is a full-service investment banking and financial services firm and therefore engages in activities where Morgan Stanley’s interests or the interests of its clients may conflict with the interests of a Fund or Portfolio, as applicable (collectively, for purposes of this section, “Fund” or “Funds”). Morgan Stanley advises clients and sponsors, manages or advises other investment funds and investment programs, accounts and businesses (collectively, together with any new or successor funds, programs, accounts or businesses, the ‘‘Affiliated Investment Accounts’’) with a wide variety of investment objectives that in some instances may overlap or conflict with a Fund’s investment objectives and present conflicts of interest. In addition, Morgan Stanley may also from time to time create new or successor Affiliated Investment Accounts that may compete with a Fund and present similar conflicts of interest. The discussion below enumerates certain actual, apparent and potential conflicts of interest. There is no assurance that conflicts of interest will be resolved in favor of Fund shareholders and, in fact, they may not be. Conflicts of interest not described below may also exist.

For more information about conflicts of interest, see the section entitled “Potential Conflicts of Interest” in the SAI.

Eaton Vance Richard Bernstein Funds47Prospectus dated January 1, 2022

Stanley has established certain information barriers and other policies to address the sharing of information between different businesses within Morgan Stanley. In limited circumstances, however, including for purposes of managing business and reputational risk, and subject to policies and procedures and any applicable regulations, Morgan Stanley personnel, including personnel of the investment adviser, on one side of an information barrier may have access to information and personnel on the other side of the information barrier through “wall crossings.” The investment adviser faces conflicts of interest in determining whether to engage in such wall crossings. Information obtained in connection with such wall crossings may limit or restrict the ability of the investment adviser to engage in or otherwise effect transactions on behalf of the Fund(s) (including purchasing or selling securities that the investment adviser may otherwise have purchased or sold for a Fund in the absence of a wall crossing).

Investments by Morgan Stanley and its Affiliated Investment Accounts. In serving in multiple capacities to Affiliated Investment Accounts, Morgan Stanley, including the investment adviser and its investment teams, may have obligations to other clients or investors in Affiliated Investment Accounts, the fulfillment of which may not be in the best interests of a Fund or its shareholders. A Fund’s investment objectives may overlap with the investment objectives of certain Affiliated Investment Accounts. As a result, the members of an investment team may face conflicts in the allocation of investment opportunities among a Fund and other investment funds, programs, accounts and businesses advised by or affiliated with the investment adviser. Certain Affiliated Investment Accounts may provide for higher management or incentive fees or greater expense reimbursements or overhead allocations, all of which may contribute to this conflict of interest and create an incentive for the investment adviser to favor such other accounts. To seek to reduce potential conflicts of interest and to attempt to allocate such investment opportunities in a fair and equitable manner, the investment adviser has implemented allocation policies and procedures. These policies and procedures are intended to give all clients of the investment adviser, including the Fund(s), fair access to investment opportunities consistent with the requirements of organizational documents, investment strategies, applicable laws and regulations, and the fiduciary duties of the investment adviser.

Payments to Broker-Dealers and Other Financial Intermediaries. The investment adviser and/or EVD may pay compensation, out of their own funds and not as an expense of a Fund, to certain financial intermediaries (which may include affiliates of the investment adviser and EVD), including recordkeepers and administrators of various deferred compensation plans, in connection with the sale, distribution, marketing and retention of shares of the Fund and/or shareholder servicing. The prospect of receiving, or the receipt of, additional compensation, as described above, by financial intermediaries may provide such financial intermediaries and their financial advisors and other salespersons with an incentive to favor sales of shares of a Fund over other investment options with respect to which these financial intermediaries do not receive additional compensation (or receive lower levels of additional compensation). These payment arrangements, however, will not change the price that an investor pays for shares of a Fund or the amount that the Fund receives to invest on behalf of an investor. Investors may wish to take such payment arrangements into account when considering and evaluating any recommendations relating to Fund shares and should review carefully any disclosures provided by financial intermediaries as to their compensation. In addition, in certain circumstances, the investment adviser may restrict, limit or reduce the amount of a Fund’s investment, or restrict the type of governance or voting rights it acquires or exercises, where the Fund (potentially together with Morgan Stanley) exceeds a certain ownership interest, or possesses certain degrees of voting or control or has other interests.

Morgan Stanley Trading and Principal Investing Activities. Notwithstanding anything to the contrary herein, Morgan Stanley will generally conduct its sales and trading businesses, publish research and analysis, and render investment advice without regard for a Fund’s holdings, although these activities could have an adverse impact on the value of one or more of the Fund’s investments, or could cause Morgan Stanley to have an interest in one or more portfolio investments that is different from, and potentially adverse to, that of a Fund.

Morgan Stanley’s Investment Banking and Other Commercial Activities. Morgan Stanley advises clients on a variety of mergers, acquisitions, restructuring, bankruptcy and financing transactions. Morgan Stanley may act as an advisor to clients, including other investment funds that may compete with a Fund and with respect to investments that a Fund may hold. Morgan Stanley may give advice and take action with respect to any of its clients or proprietary accounts that may differ from the advice given, or may involve an action of a different timing or nature than the action taken, by a Fund. Morgan Stanley may give advice and provide recommendations to persons competing with a Fund and/or any of a Fund’s investments that are contrary to the Fund’s best interests and/or the best interests of any of its investments. Morgan Stanley’s activities on behalf of its clients (such as engagements as an underwriter or placement agent) may restrict or otherwise limit investment opportunities that may otherwise be available to a Fund.

substantial part, upon the closing of the transaction. Under these circumstances, a Fund may be precluded from participating in a transaction with or relating to the company being sold or participating in any financing activity related to merger or acquisition.

General Process for Potential Conflicts. All of the transactions described above involve the potential for conflicts of interest between the investment adviser, related persons of the investment adviser and/or their clients. The Investment Advisers Act of 1940, as amended (the “Advisers Act”) the 1940 Act and ERISA impose certain requirements designed to decrease the possibility of conflicts of interest between an investment adviser and its clients. In some cases, transactions may be permitted subject to fulfillment of certain conditions. Certain other transactions may be prohibited. In addition, the investment adviser has instituted policies and procedures designed to prevent conflicts of interest from arising and, when they do arise, to ensure that it effects transactions for clients in a manner that is consistent with its fiduciary duty to its clients and in accordance with applicable law. The investment adviser seeks to ensure that potential or actual conflicts of interest are appropriately resolved taking into consideration the overriding best interests of the client.

Additional Tax Information

Each Fund expects to pay any required distributions annually, and intends to distribute any net realized capital gains annually. Distributions may not be paid if Fund (and/or Class) expenses exceed Fund income for the period. Different Classes of a Fund will generally distribute different amounts. It may also be necessary, in order to qualify for favorable tax treatment and to avoid any Fund-level tax, for each Fund to make a special income and/or capital gains distribution at the end of the calendar year.

Distributions of a Fund’s investment income (other than qualified dividend income, which is described below) and net realized short-term capital gains generally will be taxed as ordinary income. Distributions of net long-term capital gains (net gains from investments held for more than one year) generally will be taxed as long-term capital gains. Taxes on distributions of capital gains are determined by how long a Fund owned (or is treated as having owned) the investments that generated them, rather than how long a shareholder has owned his or her shares in the Fund. Distributions of investment income properly reported by a Fund as derived from “qualified dividend income” (as further described in the SAI) will be taxed in the hands of individuals at rates applicable to long-term capital gain provided holding period and other requirements are met at both the shareholder and Fund level. Over time, distributions by each Fund can generally be expected to include ordinary income, qualified dividend income and capital gain distributions taxable as long-term capital gains. A portion of each Fund’s income distributions may be eligible for the dividends-received deduction for corporations. A Fund’s distributions will be taxable as described above whether they are paid in cash or reinvested in additional shares.

Investors who purchase shares at a time when a Fund’s net asset value reflects gains that are either unrealized or realized but not distributed will pay the full price for the shares and then may receive some portion of the purchase price back as a taxable distribution. Certain distributions paid in January may be taxable to shareholders as if received on December 31 of the prior year. A redemption of Fund shares, including an exchange for shares of another fund, is generally a taxable transaction.

The net investment income of certain U.S. individuals, estates and trusts is subject to a 3.8% Medicare contribution tax. For individuals, the tax is on the lesser of the “net investment income” and the excess of modified adjusted gross income over $200,000 (or $250,000 if married filing jointly). Net investment income includes, among other things, interest, dividends, and gross income and capital gains derived from passive activities and trading in securities or commodities. Net investment income is reduced by deductions “properly allocable” to this income.

Each Fund’s investments in foreign securities may be subject to foreign withholding taxes or other foreign taxes with respect to income (possibly including, in some cases, capital gains), which may decrease the Fund’s yield on such securities. These taxes may be reduced or eliminated under the terms of an applicable tax treaty. Shareholders generally will not be entitled to claim a credit or deduction with respect to foreign taxes paid by a Fund. In addition, investments in foreign securities or foreign currencies may increase or accelerate a Fund’s recognition of ordinary income and may affect the timing or amount of the Fund’s distributions.

A Fund may be required to withhold, for U.S. federal income tax purposes, a portion of the dividends, distributions and redemption proceeds payable to shareholders who fail to provide the Fund with their correct taxpayer identification number or make required certifications, or who have been notified by the Internal Revenue Service (“IRS”) that they are subject to backup withholding. Certain shareholders are exempt from backup withholding. Backup withholding is not an additional tax and any amount withheld may be credited against a shareholder’s U.S. federal income tax liability.

Eaton Vance Richard Bernstein Funds49Prospectus dated January 1, 2022

foreign entities must certify certain information regarding their direct and indirect U.S. owners to a Fund. In addition, the IRS and the Department of Treasury have issued proposed regulations providing that these withholding rules will not be applicable to the gross proceeds of share redemptions or capital gain dividends the Fund pays. For more detailed information regarding FATCA withholding and compliance, please refer to the SAI.

Shareholders should consult with their tax advisors concerning the applicability of federal, state, local and other taxes to an investment.

Appendix A

Financial Intermediary Sales Charge Variations

As noted under “Purchasing Shares,” a financial intermediary may offer Fund shares subject to variations in or elimination of the Fund sales charges (“variations”), provided such variations are described in this Prospectus. Set forth below are the variations in sales charges applicable to shares purchased through the noted financial intermediary. All variations described below are applied by, and the responsibility of, the identified financial intermediary. Variations may apply to purchases, sales, exchanges and reinvestments of Fund shares and a shareholder transacting in Fund shares through the intermediary identified below should read the terms and conditions of the variations carefully. A variation that is specific to a particular financial intermediary is not applicable to shares held directly with the Fund or through another intermediary.

Fund Purchases through Merrill Lynch

In all instances, it is the purchaser’s responsibility to notify the Fund or the purchaser’s financial intermediary at the time of purchase of any relationship or other facts qualifying the purchaser for sales charge waivers or discounts. For waivers and discounts not available through a particular intermediary, shareholders will have to purchase Fund shares directly from the Fund or through another intermediary to receive these waivers or discounts.

Shareholders purchasing Fund shares through a Merrill Lynch platform or account are eligible only for the following sales charge waivers (front-end sales charge waivers and contingent deferred, or back-end, sales charge waivers) and discounts, which may differ from those disclosed elsewhere in this Prospectus or SAI.

Policies Regarding Transactions Through Edward D. Jones & Co., L.P. (“Edward Jones”)

The following information has been provided by Edward Jones:

Effective on or after March 1, 2021, the following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as “shareholders”) purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as “breakpoints”) and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information (“SAI”) or through another broker-dealer. In all instances, it is the shareholder's responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of fund family or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation from the shareholder of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.

Breakpoints

·Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the prospectus.

Rights of Accumulation (“ROA”)

·The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of the mutual fund family held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations (“pricing groups”). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.

·The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.

·ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).

Letter of Intent (“LOI”)

·Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. If during the 13-month period the shareholder redeems any of the shares purchased pursuant to a LOI, the value of the redeemed shares will not be included for purposes of satisfying the LOI. The inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if LOI is not met.

·If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.

Front-end Sales Charge Waivers

Sales charges are waived for the following shareholders and in the following situations:

·Associates of Edward Jones and its affiliates and their family members who are in the same pricing group (as determined by Edward Jones under its policies and procedures) as the associate. This waiver will continue for the remainder of the associate's life if the associate retires from Edward Jones in good-standing and remains in good standing pursuant to Edward Jones' policies and procedures.

·Shares purchased in an Edward Jones fee-based program.

·Shares purchased through reinvestment of capital gains distributions and dividend reinvestment.

Eaton Vance Richard Bernstein Funds62Prospectus dated January 1, 2022

·Shares purchased from the proceeds of redeemed shares of the same fund family so long as the following conditions are met: 1) the proceeds are from the sale of shares within 60 days of the purchase, and 2) the sale and purchase are made in the same share class and the same account or the purchase is made in an individual retirement account with proceeds from liquidations in a non-retirement account.

·Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of Edward Jones. Edward Jones is responsible for any remaining Contingent Deferred Sales Charge (“CDSC”) due to the fund company or its affiliate, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.

·Exchanges from Class C shares to Class A shares of the same fund, generally, in the 84th month following the anniversary of the purchase date or earlier at the discretion of Edward Jones.

CDSC Waivers

If the shareholder purchases shares that are subject to a CDSC and those shares are redeemed before the CDSC is expired, the shareholder is responsible to pay the CDSC except in the following conditions:

·The death or disability of the shareholder.

·Systematic withdrawals with up to 10% per year of the account value.

·Return of excess contributions from an Individual Retirement Account (IRA).

·Shares sold as part of a required minimum distribution for IRA and retirement accounts if the redemption is taken in or after the year the shareholder reaches qualified age based on applicable IRS regulations.

Eaton Vance Worldwide Health Sciences Fund 2Prospectus dated January 1, 2022

Portfolio Turnover

Principal Investment Strategies

The Fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities (primarily common stocks) of companies principally engaged in the discovery, development, production or distribution of products (or services) related to scientific advances in health care, including biotechnology, pharmaceuticals, diagnostics, managed health care and medical equipment and supplies (“health sciences companies”) (the “80% Policy”). A company will be considered to be a health sciences company if, at the time of investment, 50% or more of the company’s sales, earnings or assets will arise from or will be dedicated to the application of scientific advances related to health care. The Fund invests in U.S. and foreign securities and will normally be invested in issuers located in and tied economically to at least three different countries. The Fund may invest in securities of both larger established and smaller emerging companies domiciled in developed or emerging markets, some of which may be denominated in foreign currencies or trade in the form of depositary receipts. The Fund has a policy of investing at least 25% of its assets in investments in the medical research and health care industry. Companies in the medical research and health care industry are categorized by the Global Industry Classification Standard as pharmaceuticals, biotechnology, life sciences and health care equipment and services companies. The Fund may invest up to 5% of its total assets in royalty bonds, which are debt securities that are collateralized by royalties from pharmaceutical patents. The Fund may also invest in exchange-traded funds (“ETFs”), a type of pooled investment vehicle, in order to manage cash positions or seek exposure to certain markets or market sectors and may lend its securities.

The Fund may engage in derivative transactions to seek return, to hedge against fluctuations in securities prices or currency exchange rates, or as a substitute for the purchase or sale of securities or currencies. The Fund expects to use derivatives primarily to seek to generate income by writing covered call options or put options. The Fund may also enter into a combination of option transactions on individual securities. In addition, the Fund may seek to hedge against fluctuations in currency exchange rates through the use of forward foreign currency exchange contracts. Permitted derivatives include: the purchase or sale of forward or futures contracts; options on futures contracts; exchange-traded and over-the-counter options; equity collars and equity swap agreements. The Fund may also engage in covered short sales (on individual securities held or on an index or basket of securities whose constituents are held in whole or in part or for which liquid assets have been segregated). There is no stated limit on the Fund’s use of derivatives.

Investment decisions are made primarily on the basis of fundamental research. The portfolio managers seek to purchase stocks that are reasonably priced in relation to their fundamental value, and that they believe will grow in value over time regardless of short-term market fluctuations. In making investment decisions, the portfolio managers utilize the information provided by, and the expertise of, the investment adviser’s and sub-adviser’s research staff. In selecting stocks, the portfolio managers consider (among other factors) a company’s earnings or cash flow capabilities, dividend prospects, financial strength, growth potential, the strength of the company’s business franchises and management team, sustainability of a company’s competitiveness, estimates of the company’s net value, the potential to increase market share (for larger companies), and the potential of research and development projects (for smaller companies). The portfolio managers may consider selling a holding whenever there is a fundamental change to the investment thesis, the investment’s valuation target is reached, a security’s price falls below acquisition cost or to pursue more attractive investment opportunities. The portfolio managers seek to manage investment risk by maintaining issuer diversification among the Fund’s holdings, and by conducting an analysis of the risk and return characteristics of securities (as described above) in which the Fund invests. The portfolio managers may also consider financially material environmental, social and governance factors in evaluating an issuer. These considerations may be taken into account alongside other fundamental research in the securities selection process.

Principal Risks

Eaton Vance Worldwide Health Sciences Fund 3Prospectus dated January 1, 2022

Monetary and/or fiscal actions taken by U.S. or foreign governments to stimulate or stabilize the global economy may not be effective and could lead to high market volatility.

Health Sciences Concentration Risk. Because the Fund invests a significant portion of its assets in pharmaceutical, biotechnology, life sciences, and health care equipment and services companies, the value of Fund shares may be affected by developments that adversely affect such companies and may fluctuate more than that of a fund that invests more broadly. These developments include product obsolescence, the failure of a company to develop new products and the expiration of patent rights. The value of Fund shares can also be impacted by regulatory activities that affect health sciences companies. For instance, increased regulation can increase the cost of bringing new products to market and thereby reduce profits. The Fund has historically held approximately 60 stocks or less at any one time; therefore, the Fund is more sensitive to developments affecting particular stocks than would be a fund that invests more broadly.

Eaton Vance Worldwide Health Sciences Fund 4Prospectus dated January 1, 2022

may substantially exceed the initial investment, particularly when there is no stated limit on the Fund’s use of derivatives. A derivative investment also involves the risks relating to the reference instrument underlying the investment.

Royalty Bonds Risk. Royalty Bonds are typically offered in a private placement pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended, and are restricted as to resale. Because Royalty Bonds are restricted securities and because of the proprietary nature of the underlying pharmaceutical product licenses, it may take longer to liquidate Royalty Bond positions than would be the case for other securities. Royalty Bonds are also subject to the industry risks associated with health sciences companies.

Restricted Securities Risk. Unless registered for sale to the public under applicable federal securities law, restricted securities can be sold only in private transactions to qualified purchasers pursuant to an exemption from registration. The sale price realized from a private transaction could be less than the Fund’s purchase price for the restricted security. It may be difficult to identify a qualified purchaser for a restricted security held by the Fund and such security could be deemed illiquid. It may also be more difficult to value such securities.

Risks Associated with Active Management. The success of the Fund’s investment strategy depends on portfolio management’s successful application of analytical skills and investment judgment. Active management involves subjective decisions.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and how the Fund’s average annual returns over time compare with those of two broad-based securities market indices. The returns in the bar chart are for Class A shares and do not reflect a sales charge. If the sales charge was reflected, the returns would be lower. Past performance (both before and after taxes) is not necessarily an indication of how the Fund will perform in the future. The Fund’s performance reflects the effects of expense reductions. Absent these reductions, performance would have been lower. Updated Fund performance information can be obtained by visiting www.eatonvance.com.

You may purchase, redeem or exchange Fund shares on any business day, which is any day the New York Stock Exchange is open for business. You may purchase, redeem or exchange Fund shares either through your financial intermediary or (except for purchases of Class C shares by accounts with no specified financial intermediary) directly from the Fund either by writing to the Fund, P.O. Box 9653, Providence, RI 02940-9653, or by calling 1-800-262-1122. The minimum initial purchase or exchange into the Fund is $1,000 for each Class (with the exception of Class I) and $250,000 for Class I (waived in certain circumstances). There is no minimum for subsequent investments.

Tax Information

If your shares are held in a taxable account, the Fund’s distributions will be taxed to you as ordinary income and/or capital gains, unless you are exempt from taxation. If your shares are held in a tax-advantaged account, you will generally be taxed only upon withdrawals from the account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund’s shares through a broker-dealer or other financial intermediary (such as a bank) (collectively, “financial intermediaries”), the Fund, its principal underwriter and its affiliates may pay the financial intermediary for the sale of Fund shares and related services. These payments 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.

Investment Objective & Principal Policies and Risks

The investment objective and principal investment policies and risks of the Fund are described in its Fund Summary. Set forth below is additional information about such policies and risks, as well as information about other types of investments and practices in which the Fund may engage from time to time. See also “Strategies and Risks” in the Statement of Additional Information (“SAI”).

Health Sciences Companies. Health sciences companies are companies principally engaged in the discovery, development, production or distribution of products (or services) related to scientific advances in health care, including biotechnology, pharmaceuticals, diagnostics, managed health care and medical equipment and supplies. A company will be considered to be a health sciences company if, at the time of investment, 50% or more of the company’s sales, earnings or assets will arise from or will be dedicated to the application of scientific advances related to health care. The Fund has a policy of investing at least 25% of its assets in investments in the medical research and health care industry. Companies in the medical research and health care industry are categorized by the Global Industry Classification Standard as pharmaceuticals, biotechnology, life sciences and health care equipment and services companies.

Many health sciences companies are subject to substantial governmental regulations that can affect their prospects. Changes in governmental policies, such as reductions in the funding of third-party payment programs, may have a material effect on the demand for particular health care products and services. Regulatory approvals (often entailing lengthy application and testing procedures) are also generally required before new drugs and certain medical devices and procedures may be introduced. Many of the products and services of companies engaged in medical research and health care are also subject to relatively high risks of rapid obsolescence caused by progressive scientific and technological advances. Additionally, such products are subject to risks such as the appearance of toxic effects following commercial introduction and manufacturing difficulties. The enforcement of patent, trademark and other intellectual property laws will affect the value of many such companies. Health sciences companies include companies that offer limited products or services or that are at the research and developmental stage with no marketable or approved products or technologies.

Eaton Vance Worldwide Health Sciences Fund 8Prospectus dated January 1, 2022

the Fund and increased transaction costs. If a deterioration occurs in a country's balance of payments, the country could impose temporary restrictions on foreign capital remittances. The Fund could also be adversely affected by delays in, or a refusal to grant, any required governmental approval for repatriation, as well as by other restrictions on investment. The risks posed by such actions with respect to a particular foreign country, its nationals or industries or businesses within the country may be heightened to the extent the Fund invests significantly in the affected country or region or in issuers from the affected country that depend on global markets.

Emerging Markets Investments. The risks of foreign investments can be more significant in emerging markets. Emerging markets may offer higher potential for gains and losses than investments in the developed markets of the world. Political and economic structures in emerging market countries generally lack the social, political and economic stability of developed countries, which may affect the value of the Fund’s investments in these countries and also the ability of the Fund to access markets in such countries. Securities markets within emerging market countries may experience low or non-existent trading volume, resulting in a lack of liquidity and increased volatility in prices for such securities, as compared to securities of comparable issuers in more developed capital markets. Governmental actions can have a significant effect on the economic conditions in emerging market countries, which also may adversely affect the value and liquidity of the Fund’s investments. In particular, trade disputes may result in governmental actions that could have an adverse effect on investments in emerging market countries, including but not limited to restrictions on investments in, or required divestment of, particular issuers or industries. Such actions may effectively restrict or eliminate the Fund's ability to purchase or sell investments in emerging market countries, and thus may make them less liquid or more difficult to value, or may force the Fund to sell or otherwise dispose of such investments at inopportune times or prices. There may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed capital markets, and such issuers may not be subject to accounting, auditing and financial reporting standards and requirements comparable to those to which U.S. companies are subject . The laws of emerging market countries relating to the limited liability of corporate shareholders, fiduciary duties of officers and directors, and bankruptcy of state enterprises are generally less developed than or different from such laws in the United States. It may be more difficult to make a claim or obtain a judgment in the courts of these countries than it is in the United States. In addition, due to jurisdictional limitations, U.S. authorities (e.g., SEC and the U.S. Department of Justice) may be limited in their ability to enforce regulatory or legal obligations in emerging market countries. The possibility of fraud, negligence, undue influence being exerted by an issuer or refusal to recognize ownership exists in some emerging markets. The prices at which investments may be acquired may be affected by trading by persons with information that is not publicly available and by securities transactions by brokers in anticipation of transactions in particular securities. Disruptions due to work stoppages and trading improprieties in foreign securities markets have caused such markets to close. If extended closings were to occur in stock markets where the Fund is heavily invested, the Fund’s ability to redeem Fund shares could become impaired. In such circumstances, the Fund may have to sell more liquid securities than it would otherwise choose to sell. Emerging market securities are also subject to speculative trading, which contributes to their volatility.

Eaton Vance Worldwide Health Sciences Fund 9Prospectus dated January 1, 2022

Foreign Currencies. The value of foreign assets and currencies as measured in U.S. dollars may be affected favorably or unfavorably by changes in foreign currency rates and exchange control regulations, application of foreign tax laws (including withholding tax), governmental administration of economic or monetary policies (in this country or abroad), and relations between nations and trading. Foreign currencies also are subject to settlement, custodial and other operational risks. Currency exchange rates can be affected unpredictably by intervention, or the failure to intervene, by U.S. or foreign governments or central banks or by currency controls or political developments in the United States or abroad. If the U.S. dollar rises in value relative to a foreign currency, a security denominated in that foreign currency will be worth less in U.S. dollars. If the U.S. dollar decreases in value relative to a foreign currency, a security denominated in that foreign currency will be worth more in U.S. dollars. A devaluation of a currency by a country’s government or banking authority will have a significant impact on the value of any investments denominated in that currency. Costs are incurred in connection with conversions between currencies.

Derivatives. Generally, derivatives can be characterized as financial instruments whose performance is derived at least in part from the performance of an underlying reference instrument. Derivative instruments may be acquired in the United States or abroad consistent with the Fund’s investment strategy and may include the various types of exchange-traded and over-the-counter (“OTC”) instruments described herein and other instruments with substantially similar characteristics and risks. Fund obligations created pursuant to derivative instruments may give rise to leverage, which would subject the Fund to the requirements described under “Asset Coverage” in the Fund’s SAI. The Fund may invest in a derivative transaction if it is permitted to own, invest in, or otherwise have economic exposure to the reference instrument. Depending on the type of derivative instrument and the Fund’s investment strategy, a reference instrument could be a security, instrument, index, currency, commodity, economic indicator or event (“reference instruments”). The Fund may engage in derivative transactions to seek return, to hedge against fluctuations in securities prices or currency exchange rates, or as a substitute for the purchase or sale of securities or currencies. The Fund may trade in the specific type(s) and/or combinations of derivative transactions listed below.

Eaton Vance Worldwide Health Sciences Fund 10Prospectus dated January 1, 2022

new regulations will, upon implementation, eliminate the current asset segregation framework for covering derivatives and certain other financial instruments, impose new responsibilities on the Board and establish new reporting and recordkeeping requirements for a Fund and may, depending on the extent to which a Fund uses derivatives, impose value at risk limitations on a Fund’s use of derivatives, and require the Fund’s Board to adopt a derivative risk management program. The implementation of these requirements may limit the ability of a Fund to use derivative instruments as part of its investment strategy, increase the costs of using these instruments or make them less effective. Additional future regulation of the derivatives markets may make the use of derivatives more costly, may limit the availability or reduce the liquidity of derivatives, and may impose limits or restrictions on the counterparties with which the Fund engages in derivative transactions. Fund management cannot predict the effects of any new governmental regulation that may be implemented, and there can be no assurance that any new government regulation will not adversely affect the Fund’s performance or ability to achieve its investment objectives.

The Fund may also write (i.e., sell) a call option on a security or index in return for a premium. A call written on a security obligates the Fund to deliver the underlying security at the option exercise price. Written index call options obligate the Fund to make a cash payment to the buyer at expiration if the market price of the index is above the option strike price. Calls typically can also be bought back by the Fund at prevailing market prices and the Fund also may enter into closing purchase transactions with respect to written call options. The Fund may write call options on securities that is owns (so-called covered calls) and also may write uncovered call options. With respect to written covered calls, the Fund may sell the underlying security prior to entering into a closing purchase transaction on up to 5% of its net assets within three days of such transaction. The Fund may also engage in various types of option strategies using put and/or call options.

Eaton Vance Worldwide Health Sciences Fund 11Prospectus dated January 1, 2022

Futures Contracts. Futures are standardized, exchange-traded contracts. Futures contracts on securities obligate a purchaser to take delivery, and a seller to make delivery, of a specific amount of the financial instrument called for in the contract at a specified future date at a specified price. An index futures contract obligates the purchaser to take, and a seller to deliver, an amount of cash equal to a specific dollar amount times the difference between the value of a specific index at the close of the last trading day of the contract and the price at which the agreement is made. No physical delivery of the underlying securities in the index is made. It is the practice of holders of futures contracts to close out their positions on or before the expiration date by use of offsetting contract positions, and physical delivery of financial instruments or delivery of cash, as applicable, is thereby avoided. An option on a futures contract gives the holder the right to enter into a specified futures contract.

If the Fund does not own the securities sold short, the short sale exposes the Fund to the risk that it will be required to purchase securities to replace the borrowed securities (also known as “covering” the short position) at a time when the securities sold short have appreciated in value, thus resulting in a loss. There is no assurance that a security sold short will decline in value or make a profit for the Fund. In addition, there is no guarantee that any security needed to cover the short position will be available for purchase. Short selling carries a risk that the counterparty to the short sale may fail to honor its contract terms, causing a loss to the Fund. Further, if other short positions of the same security are closed out at the same time, a “short squeeze” can occur where demand exceeds the supply for the security sold short. A short

Eaton Vance Worldwide Health Sciences Fund 12Prospectus dated January 1, 2022

squeeze makes it more likely that the Fund will need to replace the borrowed security at an unfavorable price. If the Fund invests the proceeds received for selling securities short in other investments, the Fund is employing a form of leverage.

Royalty Bonds. Royalty bonds include debt securities collateralized by pharmaceutical royalty interests (“Royalty Bonds”). Pharmaceutical royalty streams are created when the owner of a patent on a pharmaceutical product licenses the discovery to a larger commercial entity for further development, while maintaining a royalty interest on future sales of the product. Royalty Bonds are created when the royalty owner borrows against the royalty stream by issuing debt collateralized by the royalty. Royalty Bond investors receive interest and principal payments collateralized and funded by the stream of royalty payments. Royalty Bonds are typically offered in a private placement pursuant to Section 4(a)(2) of the 1933 Act and are restricted as to resale.

Because Royalty Bonds are restricted securities and because of the proprietary nature of the underlying pharmaceutical product licenses, it may take longer to liquidate Royalty Bond positions than would be the case for other securities. Royalty Bonds are also subject to the industry risks associated with health sciences companies.

Eaton Vance Worldwide Health Sciences Fund 13Prospectus dated January 1, 2022

Money market instruments may be adversely affected by market and economic events, such as a sharp rise in prevailing short-term interest rates; adverse developments in the banking industry, which issues or guarantees many money market instruments; adverse economic, political or other developments affecting issuers of money market instruments; changes in the credit quality of issuers; and default by a counterparty.

Eaton Vance Worldwide Health Sciences Fund 14Prospectus dated January 1, 2022

Research Process. The Fund’s portfolio management utilizes information provided by, and the expertise of, the research staff of the investment adviser, sub-adviser and/or certain of their affiliates in making investment decisions. As part of the research process, portfolio management may consider financially material environmental, social and governance (“ESG”) factors. Such factors, alongside other relevant factors, may be taken into account in the Fund’s securities selection process.

Eaton Vance Worldwide Health Sciences Fund 15Prospectus dated January 1, 2022

providers rely, and could otherwise disrupt the ability of the employees of the Fund’s service providers to perform critical tasks relating to the Fund. Any such impact could adversely affect the Fund’s performance, or the performance of the securities in which the Fund invests and may lead to losses on your investment in the Fund.

General. The Fund's 80% Policy will not be changed unless shareholders are given at least 60 days’ advance written notice of the change. Unless otherwise stated, the Fund's investment objective and certain other policies may be changed without shareholder approval. Any proposed material change in the investment objective will be submitted to shareholders for their approval. The Fund might not use all of the strategies and techniques or invest in all of the types of securities described in this Prospectus or the SAI. While at times the Fund may use alternative investment strategies in an effort to limit its losses, it may choose not to do so.

Management and Organization

Management. The Fund’s investment adviser is Eaton Vance Management (“Eaton Vance”). Eaton Vance has offices at Two International Place, Boston, MA 02110. Eaton Vance and its predecessor organizations have been managing assets since 1924 and managing mutual funds since 1931. Prior to March 1, 2021, Eaton Vance was a wholly owned subsidiary of Eaton Vance Corp. (“EVC”).

On March 1, 2021, Morgan Stanley acquired EVC (the “Transaction”), and Eaton Vance became an indirect, wholly owned subsidiary of Morgan Stanley. In connection with the Transaction, the Fund entered into a new investment advisory agreement with its investment adviser and the investment adviser entered into a new investment sub-advisory agreement with its sub-adviser. Each such agreement was approved by Fund shareholders prior to the consummation of the Transaction and was effective upon its closing.

Pursuant to a sub-advisory agreement, Eaton Vance has delegated a portion of the investment management of the Fund to Eaton Vance Advisers International Ltd. (“EVAIL”), 125 Old Broad Street, London, EC2N 1AR, United Kingdom, a registered investment adviser. Eaton Vance pays EVAIL a portion of its advisory fee for sub-advisory services provided to the Fund. On March 1, 2021, upon the closing of the Transaction, EVAIL became an indirect wholly owned subsidiary of Morgan Stanley. Prior to March 1, 2021, EVAIL was an indirect wholly owned subsidiary of EVC.

The Fund’s semiannual report covering the fiscal period ended February 28 provides information regarding the basis for the Trustees’ approval of the Fund’s investment advisory and sub-advisory agreements.

Eaton Vance receives a monthly asset-based investment advisory fee from the Fund as follows:

Average Daily Net Assets for the Month	Annual Fee Rate
Up to $500 million	0.675%
$500 million but less than $1 billion	0.590%
$1 billion but less than $1.5 billion	0.520%
$1.5 billion but less than $2 billion	0.490%
$2 billion but less than $2.5 billion	0.470%
$2.5 billion and over	0.450%

Eaton Vance Worldwide Health Sciences Fund 16Prospectus dated January 1, 2022

Eaton Vance may receive a performance-based upward or downward adjustment to the asset-based investment advisory fee of up to 0.15% (annually) of the average daily net assets of the Fund depending upon whether, and to what extent, the investment performance of the Fund differs by at least one percentage point from the record of the MSCI World Health Care Index over a 36-month performance period. For the fiscal year ended August 31, 2021, the annual effective rate of the investment advisory fee paid to Eaton Vance, including an upward performance adjustment, was 0.63% of the Fund’s average daily net assets.

The Fund is managed by Jason Kritzer and Samantha Pandolfi. Prior to the close of business on August 9, 2019, Mr. Kritzer and Ms. Pandolfi managed Worldwide Health Sciences Portfolio (the “Portfolio”) in which the Fund previously invested. Mr. Kritzer has served as a portfolio manager since July 2016, has been a portfolio manager at Eaton Vance for more than five years and is a Vice President of Eaton Vance. Ms. Pandolfi has served as a portfolio manager since July 2016 and is a Vice President of EVAIL. Prior to joining EVAIL in November 2017, Ms. Pandolfi held identical positions at Eaton Vance Management (International) Limited (“EVMI”) (2015-2017).

The SAI provides additional information about the investment management team, including information about compensation, other accounts managed by the team members, and each team member’s ownership of Fund shares.

Pursuant to an Amended and Restated Administrative Services Agreement, Eaton Vance receives a monthly fee from the Fund for administrative services of 0.15% annually of average daily net assets. For the fiscal year ended August 31, 2021, the administration fee amounted to 0.15% of the average daily net assets of the Fund.

Organization. The Fund is a series of Eaton Vance Growth Trust, a Massachusetts business trust. The Fund offers multiple classes of shares. Each Class represents a pro rata interest in the Fund but is subject to different expenses and rights. The Fund does not hold annual shareholder meetings but may hold special meetings for matters that require shareholder approval (such as electing or removing Trustees, approving management or advisory contracts or changing investment policies that may only be changed with shareholder approval).

Valuing Shares

The Fund values its shares once each day only when the New York Stock Exchange (the “Exchange”) is open for trading (typically Monday through Friday), as of the close of regular trading on the Exchange (normally 4:00 p.m. Eastern Time). If trading on the Exchange is halted for the day before the scheduled close of regular trading, the Fund’s net asset value per share generally will still be calculated as of the scheduled close of regular trading on the Exchange. The purchase price of Fund shares is their net asset value (plus any applicable sales charge), which is derived from the value of Fund holdings. When purchasing or redeeming Fund shares through a financial intermediary, your financial intermediary must receive your order by the close of regular trading on the Exchange in order for the purchase price or the redemption price to be based on that day’s net asset value per share. It is the financial intermediary’s responsibility to transmit orders promptly. The Fund may accept purchase and redemption orders as of the time of their receipt by certain financial intermediaries (or their designated intermediaries).

The Board has adopted procedures for valuing investments (the “Procedures”) and has delegated to the investment adviser(s) the daily valuation of such investments. Pursuant to the Procedures, securities and other investments held by the Fund are generally valued at market value. Exchange-listed investments (including certain derivatives) are normally valued at last sale or closing prices. Exchange-traded options are valued at the mean of the bid and asked prices at valuation time as reported by the Options Price Reporting Authority for U.S. listed options, or by the relevant exchange or board of trade for non-U.S. listed options. Non-exchange traded derivatives are normally valued on the basis of quotes obtained from brokers and dealers or independent pricing services. Most loans and other debt obligations are valued using prices supplied by one or more pricing services.

An instrument’s “fair value” is the amount that the owner might reasonably expect to receive for the instrument upon its current sale in the ordinary course of business. Under certain limited circumstances, the Fund may use fair value pricing if, for example, market prices or a pricing service's prices (as applicable) are unavailable or deemed unreliable, or if events occur after the close of a securities market (usually a foreign market) and before portfolio assets are valued that cause or are likely to cause a market quotation to be unavailable or unreliable, such as corporate actions, regulatory news, or natural disasters or governmental actions that may affect investments in a particular sector, country or region. In addition, for foreign equity securities and total return swaps and futures contracts on foreign indices that meet certain criteria, the Board has approved the use of a fair value service that values such investments to reflect market trading that occurs after the close of the applicable foreign markets of comparable securities or other investment that have a strong correlation to the fair valued investments. An investment that is fair valued may be valued at a price higher or lower than (i) actual market quotations, (ii) the value determined by other funds using their own fair valuation procedures, or (iii) the

Eaton Vance Worldwide Health Sciences Fund 17Prospectus dated January 1, 2022

price at which the investment could have been sold during the period in which fair valuation was used with respect to such investment to calculate the Fund’s NAV. Because foreign investments held by the Fund, if any, may trade on days when Fund shares are not priced, the value of such investments, and thus the net asset value of the Fund's shares, can change on days when Fund shares cannot be redeemed or purchased. Eaton Vance has established a Valuation Committee that oversees the valuation of investments.

Purchasing Shares

Set forth below is information about the manner in which the Fund offers shares. A financial intermediary may offer Fund shares subject to variations in or elimination of the Fund sales charges (“variations”), provided such variations are described in this Prospectus. All variations described in Appendix A are applied by, and the responsibility of, the identified financial intermediary. Sales charge variations may apply to purchases, sales, exchanges and reinvestments of Fund shares and a shareholder transacting in Fund shares through an intermediary identified on Appendix A should read the terms and conditions of Appendix A carefully. See also “Shareholder Account Features – ‘Street Name’ Accounts.” For the variations applicable to shares offered through certain financial intermediaries, please see Appendix A – Financial Intermediary Sales Charge Variations. A variation that is specific to a particular financial intermediary is not applicable to shares held directly with the Fund or through another intermediary.

You may purchase shares through your financial intermediary or by mailing an account application form to the transfer agent (see back cover for address). Purchase orders will be executed at the net asset value (plus any applicable sales charge) next determined after their receipt in proper form (meaning that the order is complete and contains all necessary information) by the Fund’s transfer agent. The Fund’s transfer agent or your financial intermediary must receive your purchase in proper form no later than the close of regular trading on the Exchange (normally 4:00 p.m. Eastern Time) for your purchase to be effected at that day’s net asset value. If you purchase shares through a financial intermediary, that intermediary may charge you a fee for executing the purchase for you.

The Fund may suspend the sale of its shares at any time and any purchase order may be refused for any reason. The U.S. registered funds sponsored by the Eaton Vance organization (the “Eaton Vance funds”) generally do not accept investments from residents of the European Union, the United Kingdom or Switzerland. The funds also do not accept investments from other non-U.S. residents, provided that a fund may accept investments from certain non-U.S. investors at the discretion of the principal underwriter. The Fund does not issue share certificates.

Class A, Class C and Class R Shares

Your initial investment must be at least $1,000. After your initial investment, additional investments may be made in any amount at any time by sending a check payable to the order of the Fund or the transfer agent directly to the transfer agent (see back cover for address). Please include your name and account number and the name of the Fund and Class of shares with each investment. The Fund no longer accepts direct purchases of Class C shares by accounts for which no broker-dealer or other financial intermediary is specified. Any direct purchase received by the Fund's transfer agent for Class C shares for such accounts will automatically be invested in Class A shares.

Class I Shares

Your initial investment must be at least $250,000, except as noted below. Class I shares are offered to clients of financial intermediaries who (i) charge such clients an ongoing fee for advisory, investment, consulting or similar services, or (ii) have entered into an agreement with the principal underwriter to offer Class I shares through a no-load network or platform. Such clients may include individuals, corporations, endowments, foundations and employer sponsored retirement plans. Class I shares may also be available through brokerage platforms of broker-dealer firms that have agreements with the Fund’s principal underwriter to offer Class I shares solely when acting as an agent for the investor. An investor acquiring Class I shares through such platforms may be required to pay a commission and/or other forms of compensation to the broker. The Fund offers other share classes that have different fees and expenses. Class I shares

Eaton Vance Worldwide Health Sciences Fund 18Prospectus dated January 1, 2022

also are offered to investment and institutional clients of Eaton Vance and its affiliates and certain persons affiliated with Eaton Vance.

Restrictions on Excessive Trading and Market Timing. The Fund is not intended for excessive trading or market timing. Market timers seek to profit by rapidly switching money into a fund when they expect the share price of the fund to rise and taking money out of the fund when they expect those prices to fall. By realizing profits through short-term trading, shareholders that engage in rapid purchases and sales (including exchanges, if permitted) of a fund’s shares may dilute the value of shares held by long-term shareholders. Volatility resulting from excessive purchases and sales of fund shares, especially involving large dollar amounts, may disrupt efficient portfolio management. In particular, excessive purchases and sales of a fund’s shares may cause a fund to have difficulty implementing its investment strategies, may force the fund to sell portfolio securities at inopportune times to raise cash or may cause increased expenses (such as increased brokerage costs, realization of taxable capital gains without attaining any investment advantage or increased administrative costs).

Eaton Vance Worldwide Health Sciences Fund 19Prospectus dated January 1, 2022

ability of a shareholder to invest in the Eaton Vance funds if Eaton Vance determines that a proposed transaction involves market timing or excessive trading that it believes is likely to be detrimental to the Fund.

Pursuant to the Policy, two “round-trips” completed by a Fund shareholder within 90 days through one or more accounts (the “Limitation”) generally will be deemed to be indicative of market timing or trading excessively in fund shares. A “round trip” is defined as a purchase or exchange into a Fund followed or preceded by a redemption or exchange out of the Fund. Purchases and redemptions subject to the Limitation include those made by exchanging to or from another fund. Eaton Vance will evaluate transactions in Fund shares that violate the Limitation to determine whether they are likely to be detrimental to the Fund. In making such a determination, Eaton Vance may consider various factors, such as the amount, frequency and nature of trading activity. If such a determination is made, the Fund shareholder may be subject to restrictions on trading Fund shares, as described above. Eaton Vance uses reasonable efforts to detect market timing and excessive trading activity that is likely to be detrimental to the Fund, but it cannot ensure that it will be able to identify all such cases. Eaton Vance may also reject or cancel any purchase order (including an exchange) from a shareholder or group of shareholders for any other reason. In applying the Policy, and in particular when determining whether a transaction is likely to be detrimental to a Fund, Eaton Vance will be required to make judgments that are inherently subjective and will depend on the specific facts and circumstances. Such determinations will be made in a manner believed to be in the best interest of the Fund’s shareholders. No Eaton Vance fund has any arrangement to permit market timing.

The following fund share transactions generally are exempt from the Policy because they generally do not raise market timing or excessive trading concerns:

·transactions (i) made pursuant to the Fund’s systematic purchase, exchange or redemption plan, (ii) made as the result of automatic reinvestment of dividends or distributions, or (iii) initiated by the Fund (e.g., for transactions due to a failure to meet applicable account minimums);

·transactions in shares of Eaton Vance Short Duration Government Income Fund; or

·investments in a fund by ReFlow in connection with the ReFlow liquidity program (if applicable to the Fund, the ReFlow liquidity program is described under “Investment Objectives & Principal Policies and Risks” above).

·transactions made by model-based discretionary advisory accounts; or

·transactions made by funds that invest in the Fund as part of an asset reallocation in accordance with their investment policies or in response to Fund inflows and outflows.

It may be difficult for Eaton Vance to identify market timing or excessive trading in omnibus accounts traded through financial intermediaries. Eaton Vance has provided guidance to financial intermediaries (such as banks, broker-dealers, insurance companies and retirement administrators) concerning the application of the Policy to Fund shares held in omnibus accounts maintained and administered by such intermediaries, including guidance concerning situations where market timing or excessive trading is considered to be detrimental to the Fund. Eaton Vance may rely on a financial intermediary’s policy to restrict market timing and excessive trading if it believes that policy is likely to prevent market timing that is likely to be detrimental to the Fund. Such policy may be more or less restrictive than the Policy. Although Eaton Vance reviews trading activity at the omnibus account level for activity that indicates potential market timing or excessive trading activity, Eaton Vance typically will not request or receive individual account data unless suspicious trading activity is identified. Eaton Vance generally relies on financial intermediaries to monitor trading activity in omnibus accounts in good faith in accordance with their own policies or the Policy. Eaton Vance cannot ensure that these financial intermediaries will in all cases apply the Policy or their own policies, as the case may be, to accounts under their control.

Choosing a Share Class. The Fund offers different classes of shares. The different classes of shares represent investments in the same portfolio of securities, but the classes are subject to different expenses and privileges, and will likely have different share prices due to differences in class expenses. A share class also may be subject to a sales charge. In choosing the class of shares that suits your investment needs, you should consider:

·how long you expect to own your shares;

·how much you intend to invest; and

·the total operating expenses associated with owning each class.

Eaton Vance Worldwide Health Sciences Fund 20Prospectus dated January 1, 2022

Class C shares are offered through financial intermediaries at net asset value with no front-end sales charge. If you sell your Class C shares within 12 months of purchase, you generally will be subject to a contingent deferred sales charge or “CDSC.” The CDSC is deducted from your redemption proceeds. Under certain circumstances, the CDSC for Class C may be waived (such as certain redemptions from employer sponsored retirement plans). See “CDSC Waivers” under “Sales Charges” below. Class C shares pay distribution and service fees equal to 1.00% annually of average daily net assets. Orders for Class C shares of one or more Eaton Vance funds will be refused when the total value of the purchase (including the aggregate market value of all Eaton Vance fund shares held within the purchasing shareholder’s account(s)) is $1 million or more. Investors considering cumulative purchases of $1 million or more should consider whether another Class of shares would be more appropriate and consult their financial intermediary. The Fund no longer accepts direct purchases of Class C shares by accounts for which no broker-dealer or other financial intermediary is specified. Any direct purchase received by the Fund’s transfer agent for Class C shares for such accounts will automatically be invested in Class A shares. In addition, Class C shares held in an account for which no financial intermediary is specified and which are not subject to a CDSC will periodically be converted to Class A shares.

Class R shares are offered at net asset value with no front-end sales charge to employer sponsored retirement plans and Individual Retirement Account rollover clients of financial intermediaries who charge such clients an ongoing fee for advisory, investment, consulting or similar services. Class R shares pay distribution and service fees equal to 0.50% annually of average daily net assets.

Reducing or Eliminating Class A Sales Charges. Front-end sales charges on purchases of Class A shares may be reduced under the right of accumulation or under a statement of intention. To receive a reduced sales charge, you must inform your financial intermediary or the Fund at the time you purchase shares that you qualify for such a reduction. If you do not let your financial intermediary or the Fund know you are eligible for a reduced sales charge at the time of purchase, you will not receive the discount to which you may otherwise be entitled.

Right of Accumulation. Under the right of accumulation, the sales charge you pay is reduced if the current market value of your holdings in the Fund or any other Eaton Vance fund (based on the current maximum public offering price) plus your new purchase total $50,000 or more. Shares owned by you, your spouse and children under age twenty-one may be combined for purposes of the right of accumulation, including shares held for the benefit of any of you in omnibus or “street name” accounts. In addition, shares held in a trust or fiduciary account of which any of the foregoing persons is the sole beneficiary (including employer sponsored retirement plans and IRAs) may be combined for purposes of the right of accumulation. Shares purchased and/or owned in a SEP, SARSEP and SIMPLE IRA plan may be combined for purposes of the right of accumulation for the plan and its participants. You may be required to provide documentation to establish your ownership of shares included under the right of accumulation (such as account statements for you, your spouse and children or marriage certificates, birth certificates and/or trust or other fiduciary-related documents).

Statement of Intention. Under a statement of intention, purchases of $50,000 or more made over a 13-month period are eligible for reduced sales charges. Shares eligible under the right of accumulation (other than those included in employer sponsored retirement plans) may be included to satisfy the amount to be purchased under a statement of intention. Under a statement of intention, the principal underwriter may hold 5% of the dollar amount to be purchased in escrow in the form of shares registered in your name until you satisfy the statement or the 13-month period expires. A statement of intention does not obligate you to purchase (or the Fund to sell) the full amount indicated in the statement. If during the 13-month period you redeem any of the shares that you purchased pursuant to the statement of intention, the value of the redeemed shares will not be included for purposes of satisfying your statement of intention. For additional information about statements of intention, see “Sales Charges” in the SAI.

Eaton Vance Worldwide Health Sciences Fund 22Prospectus dated January 1, 2022

transfer or roll-over at the time of the account opening. Class A shares may also be purchased at net asset value pursuant to the exchange privilege and when distributions are reinvested. A financial intermediary may not, in accordance with its policies and procedures, offer one or more of the waiver categories described above and shareholders should consult their financial intermediary for more information. The Fund may eliminate, modify or add to the terms of these sales charge waivers at any time without providing notice to shareholders.

The sales commission payable to financial intermediaries in connection with sales of Class C shares is described under “Distribution and Service Fees” below.

CDSC Waivers. CDSCs are waived for certain redemptions pursuant to a Withdrawal Plan (see “Shareholder Account Features”) and in connection with certain redemptions from employer sponsored retirement plans or IRAs to satisfy required minimum distributions or to return excess contributions made to IRAs, if applicable. The CDSC is also waived following the death of a beneficial owner of shares (a death certificate and other applicable documents may be required). In addition, redemptions of Class C shares by certain employer sponsored retirement plans are not subject to a CDSC if the principal underwriter did not compensate such plans' financial intermediary at the time of sale as described under “Distribution and Service Fees.”

Conversion Feature. Effective November 5, 2020 (the “Effective Date”), Class C shares of the Fund will convert automatically to Class A shares of the Fund during the month following the eight year anniversary of the purchase of such Class C shares. If a financial intermediary that maintains a Class C shareholder’s account has not tracked the holding period for Class C shares, Class C shares held as of the Effective Date will automatically convert to Class A shares eight years after the Effective Date. In addition, Class C shares held in an account with the Fund’s transfer agent for which no financial intermediary is specified and that are not subject to a CDSC will be converted to Class A shares of the Fund periodically.

Distribution and Service Fees. Class A, Class C and Class R shares have in effect plans under Rule 12b-1 that allow the Fund to pay distribution fees for the sale and distribution of shares and service fees for personal and/or shareholder account services (so-called “12b-1 fees”). Class C shares pay distribution fees to the principal underwriter of 0.75% of average daily net assets annually. Class R shares pay distribution fees to the principal underwriter of 0.25% annually of average daily net assets and such fees are paid to financial intermediaries. Although there is no intention to do so, Class R could pay distribution fees of up to 0.50% annually upon Trustee approval. Because these fees are paid from Fund assets on an ongoing basis, they will increase your cost over time and may cost you more than paying other types of sales charges. The principal underwriter generally compensates financial intermediaries on sales of Class C shares (except exchange transactions and reinvestments) in an amount equal to 1% of the purchase price of the shares. After the first year, such financial intermediaries also receive 0.75% of the value of outstanding Class C shares sold by such financial intermediaries in annual distribution fees. With respect to purchases of Class C shares by certain employer sponsored retirement plans, the principal underwriter does not compensate the financial intermediary at the time of sale. In such cases, the financial intermediary receives 0.75% of the value of outstanding Class C shares sold by such financial intermediary in annual distribution fees immediately after the sale. Class C and Class R shares also pay service fees to the principal underwriter equal to 0.25% of average daily net assets annually. Class A shares pay distribution and service fees equal to 0.25% of average daily net assets annually. After the sale of shares, the principal underwriter generally receives the Class A distribution and service fees and the Class C service fees for one year. Thereafter financial intermediaries generally receive from the principal underwriter 0.25% annually of average daily net assets based on the value of outstanding shares sold by such financial intermediaries for shareholder servicing performed by such intermediaries. After the sale of Class R shares, the principal underwriter generally pays service fees to financial intermediaries based on the value of shares sold by such intermediaries. With respect to purchases of Class A and Class C shares by certain employer sponsored retirement plans, the financial intermediary receives the above described distribution and service fees or service fees, as applicable, from the principal underwriter immediately after the sale. Distribution and service fees are subject to the limitations contained in the sales charge rule of the Financial Industry Regulatory Authority, Inc.

Redeeming Shares

You can redeem shares in any of the following ways:

By Mail	Send your request to the transfer agent (see back cover for address). The request must be signed exactly as your account is registered (for instance, a joint account must be signed by all registered owners to be accepted) and a Medallion signature guarantee may be required. Circumstances that may require a Medallion signature guarantee include, but are not limited to, requests to distribute redemption proceeds to a party other than the registered account owner(s); requests to mail redemption proceeds to an address other than the address of record; requests to distribute proceeds to a bank account not on file; requests to re-issue uncashed checks representing redemption proceeds; or transaction requests from an account beneficiary when an account owner is deceased. You can obtain a Medallion signature guarantee at banks, savings and loan institutions, credit unions, securities dealers, securities exchanges, clearing agencies and registered securities associations that participate in The Securities Transfer Agents Medallion Program, Inc. (STAMP, Inc.). Only Medallion signature guarantees issued in accordance with STAMP, Inc. will be accepted. You may be asked to provide additional documents if your shares are registered in the name of a corporation, partnership or fiduciary.
By Telephone	Certain shareholders can redeem by calling 1-800-262-1122 Monday through Friday, 8:30 a.m. to 5:30 p.m. (Eastern Time). Proceeds of a telephone redemption are generally limited to $100,000 per account (which may include shares of one or more Eaton Vance funds) and can be sent only to the account address or to a bank pursuant to prior instructions.
By Internet	Certain shareholders can redeem by logging on to the Eaton Vance website at www.eatonvance.com. Proceeds of internet redemptions are generally limited to $100,000 per account (which may include shares of one or more Eaton Vance funds) and can be sent only to the account address or to a bank pursuant to prior instructions.
For Additional Information	Please call 1-800-262-1122 Monday through Friday, 8:30 a.m. to 5:30 p.m. (Eastern Time).
Through a Financial Intermediary	Your financial intermediary is responsible for transmitting the order promptly. A financial intermediary may charge a fee for this service.

A redemption may be requested by sending a Medallion signature guaranteed letter of instruction to the transfer agent (see back cover for address) or, for telephone redemptions as described above, by calling 1-800-262-1122. Certain redemption requests, including those involving shares held by certain corporations, trusts or certain other entities and shares that are subject to certain fiduciary arrangements, may require additional documentation and may be redeemed only by mail. The Fund's transfer agent or your financial intermediary must receive your redemption in proper form (meaning that it is complete and contains all necessary information) no later than the close of regular trading on the Exchange (normally 4:00 p.m. Eastern Time) for your redemption to be effected at that day’s net asset value. Redemption proceeds are reduced by the amount of any applicable CDSC and any federal income and state tax required to be withheld.

Eaton Vance Worldwide Health Sciences Fund 24Prospectus dated January 1, 2022

If your shares are held directly with the Fund's transfer agent, redemptions normally will be settled in one business day after the redemption date and redemption proceeds will be sent by regular mail on such date. However, if you have given proper written authorization in advance, you may request that redemption proceeds be wired on the settlement date directly to your bank account in any bank in the United States. While not currently charged by the Fund, you may be required to pay a wire transfer fee by your bank. If you request expedited mail delivery of your redemption proceeds and the Fund is able to accommodate your request, charges may apply. You may redeem all or a portion of the shares from your account on any day the Fund is open for business, provided the amount requested is not on hold or held in escrow pursuant to a statement of intention. When you purchase by check or with ACH funds transfer, the purchase will be on hold for up to 10 days from the date of receipt. During the hold period, redemption proceeds will not be sent until the transfer agent is reasonably satisfied that the purchase payment has been collected.

The Fund typically expects to meet redemption requests by (i) distributing any cash holdings, (ii) selling portfolio investments and/or (iii) borrowing from a bank under a line of credit. In addition to the foregoing, the Fund also may distribute securities as payment (a so-called “redemption in-kind”), in which case the redeeming shareholder may pay fees and commissions to convert the securities to cash. Unless requested by a shareholder, the Fund generally expects to limit use of redemption in-kind to stressed market conditions, but is permitted to do so in other circumstances. A shareholder who wishes to receive redemption proceeds in-kind must notify the Fund on or before submitting the redemption request by calling 1-800-262-1122. Securities distributed in a redemption in-kind would be valued pursuant to the Fund’s valuation procedures and selected by the investment adviser. If a shareholder receives securities in a redemption in-kind, the shareholder could incur brokerage or other charges in converting the securities to cash and the value of such securities would be subject to price fluctuations until sold. There can be no assurance that the Fund will manage liquidity successfully in all market environments. As a result, the Fund may not be able to pay redemption proceeds in a timely fashion because of unusual market conditions, an unusually high volume of redemption requests or other factors. Additional information about redemptions in-kind, including the procedures for submitting such redemption requests, is contained in the Fund’s SAI.

Shareholder Account Features

Distributions. You may have your Fund distributions paid in one of the following ways:

• Full Reinvest Option	Distributions are reinvested in additional shares. This option will be assigned if you do not specify an option.
• Partial Reinvest Option	Dividends are paid in cash* and capital gains are reinvested in additional shares.
• Cash Option	Distributions are paid in cash.*
• Exchange Option	Distributions are reinvested in additional shares of any class of another Eaton Vance fund chosen by you, subject to the terms of that fund’s prospectus. Before selecting this option, you must obtain a prospectus of the other fund and consider its objectives, risks, and charges and expenses carefully.

Information about the Fund. From time to time, you may receive the following:

·Semiannual and annual reports containing a list of portfolio holdings as of the end of the second and fourth fiscal quarters, respectively, performance information and financial statements.

·Periodic account statements, showing recent activity and total share balance.

·Tax information needed to prepare your income tax returns.

·Proxy materials, in the event a shareholder vote is required.

·Special notices about significant events affecting your Fund.

Eaton Vance Worldwide Health Sciences Fund 25Prospectus dated January 1, 2022

You may be contacted via mail, telephone or by electronic means by officers of the Fund, by personnel of the investment adviser or administrator, by the Fund’s transfer agent, by broker-dealer firms, or by a professional solicitation organization in connection with a solicitation of proxies for a meeting of Fund shareholders.

The Fund will file information regarding its portfolio holdings with the SEC on its Form N-PORT. The Fund’s annual and semiannual reports (as filed on Form N-CSR) and certain information filed on Form N-PORT may be viewed on the SEC’s website (www.sec.gov). The most recent fiscal quarter-end holdings may also be viewed on the Eaton Vance website (www.eatonvance.com). Portfolio holdings information that is filed with the SEC is posted on the Eaton Vance website approximately 60 days after the end of the quarter to which it relates. Portfolio holdings information as of each month end is posted to the website approximately one month after such month end. The Fund also posts information about certain portfolio characteristics (such as top ten holdings and asset allocation) at least quarterly on the Eaton Vance website approximately ten business days after the period and the Fund may also post performance attribution as of a month end or more frequently if deemed appropriate.

Eaton Vance Worldwide Health Sciences Fund 26Prospectus dated January 1, 2022

Telephone and Electronic Transactions. You can redeem or exchange shares by telephone as described in this Prospectus. In addition, certain transactions may be conducted through the Eaton Vance website. The transfer agent and the principal underwriter have procedures in place to authenticate telephone and electronic instructions (such as using security codes or verifying personal account information). As long as the transfer agent and principal underwriter follow reasonable procedures, they will not be responsible for unauthorized telephone or electronic transactions and you bear the risk of possible loss resulting from these transactions. You may decline the telephone redemption option on the account application. Telephone instructions are recorded. You should verify the accuracy of your confirmation statements immediately upon receipt and notify Eaton Vance Shareholder Services of any inaccuracies.

“Street Name” Accounts. If your shares are held in a “street name” account at a financial intermediary, that intermediary (and not the Fund or its transfer agent) will perform all recordkeeping, transaction processing and distribution payments. Because the Fund does not maintain an account for you, you should contact your financial intermediary to make transactions in shares, make changes in your account, or obtain account information. You will not be able to utilize a number of shareholder features, such as telephone or internet transactions, directly with the Fund and certain features may be subject to different requirements. If you transfer shares in a “street name” account to an account with another financial intermediary or to an account directly with the Fund, you should obtain historical information about your shares prior to the transfer. If you fail to provide your full account history to your new financial intermediary following a transfer, you may be ineligible for certain features of the Fund.

Procedures for Opening New Accounts. To help the government fight the funding of terrorism and money laundering activities, federal law requires financial institutions to obtain, verify and record information that identifies each new customer who opens an account with the Fund and to determine whether such person’s name appears on government lists of known or suspected terrorists or terrorist organizations. When you open an account, the transfer agent or your financial intermediary will ask you for your name, address, date of birth (for individuals), residential or business street address (although post office boxes are still permitted for mailing) and social security number, taxpayer identification number, or other government-issued identifying number. You also may be asked to produce a copy of your driver’s license, passport or other identifying documents in order to verify your identity. In addition, it may be necessary to verify your identity by cross-referencing your identification information with a consumer report or other electronic databases. Other information or documents may be required to open accounts for corporations and other entities. Federal law prohibits the Fund and other financial institutions from opening a new account unless they receive the minimum identifying information described above. If a person fails to provide the information requested, any application by that person to open a new account will be rejected. Moreover, if the transfer agent or the financial intermediary is unable to verify the identity of a person based on information provided by that person, it may take additional steps including, but not limited to, requesting additional information or documents from the person, closing the person’s account or reporting the matter to the appropriate federal authorities. If your account is closed for this reason, your shares may be automatically redeemed at the net asset value next determined. If the Fund’s net asset value has decreased since your purchase, you will lose money as a result of this redemption. The Fund has also designated an anti-money laundering compliance officer.

Potential Conflicts of Interest

As a diversified global financial services firm, Morgan Stanley, the parent company of the investment adviser and sub-adviser, engages in a broad spectrum of activities, including financial advisory services, investment management activities, lending, commercial banking, sponsoring and managing private investment funds, engaging in broker-dealer transactions and principal securities, commodities and foreign exchange transactions, research publication and other activities. In the ordinary course of its business, Morgan Stanley is a full-service investment banking and financial services firm and therefore engages in activities where Morgan Stanley’s interests or the interests of its clients may conflict with the interests of a Fund or Portfolio, as applicable (collectively, for purposes of this section, “Fund” or “Funds”). Morgan Stanley advises clients and sponsors, manages or advises other investment funds and investment programs, accounts and businesses (collectively, together with any new or successor Morgan Stanley funds, programs, accounts or businesses, (other than funds, programs, accounts or businesses sponsored, managed, or advised by former direct or indirect subsidiaries of EVC (“Eaton Vance Investment Accounts”)), the “MS Investment Accounts,” and, together with the Eaton Vance Investment Accounts, the ‘‘Affiliated Investment Accounts’’) with a wide variety of investment objectives that in some instances may overlap or conflict with a Fund’s investment objectives and present conflicts of interest. In addition, Morgan Stanley or the investment adviser may also from time to time create new or successor Affiliated Investment Accounts that may compete with a Fund and present similar conflicts of interest. The discussion below enumerates certain actual, apparent and potential conflicts of interest. There is no assurance that conflicts of interest will be resolved in favor of Fund shareholders and, in fact, they may not be. Conflicts of interest not described below may also exist.

Eaton Vance Worldwide Health Sciences Fund 27Prospectus dated January 1, 2022

The discussions below with respect to actual, apparent and potential conflicts of interest also may be applicable to or arise from the MS Investment Accounts whether or not specifically identified. For more information about conflicts of interest, see the section entitled “Potential Conflicts of Interest” in the SAI.

Material Non-public Information. It is expected that confidential or material non-public information regarding an investment or potential investment opportunity may become available to the investment adviser. If such information becomes available, the investment adviser may be precluded (including by applicable law or internal policies or procedures) from pursuing an investment or disposition opportunity with respect to such investment or investment opportunity. Morgan Stanley has established certain information barriers and other policies to address the sharing of information between different businesses within Morgan Stanley. In limited circumstances, however, including for purposes of managing business and reputational risk, and subject to policies and procedures and any applicable regulations, Morgan Stanley personnel, including personnel of the investment adviser, on one side of an information barrier may have access to information and personnel on the other side of the information barrier through “wall crossings.” The investment adviser faces conflicts of interest in determining whether to engage in such wall crossings. Information obtained in connection with such wall crossings may limit or restrict the ability of the investment adviser to engage in or otherwise effect transactions on behalf of the Fund(s) (including purchasing or selling securities that the investment adviser may otherwise have purchased or sold for a Fund in the absence of a wall crossing).

Investments by Morgan Stanley and its Affiliated Investment Accounts. In serving in multiple capacities to Affiliated Investment Accounts, Morgan Stanley, including the investment adviser, sub-adviser and its investment teams, may have obligations to other clients or investors in Affiliated Investment Accounts, the fulfillment of which may not be in the best interests of a Fund or its shareholders. A Fund’s investment objectives may overlap with the investment objectives of certain Affiliated Investment Accounts. As a result, the members of an investment team may face conflicts in the allocation of investment opportunities among a Fund and other investment funds, programs, accounts and businesses advised by or affiliated with the investment adviser or sub-adviser. Certain Affiliated Investment Accounts may provide for higher management or incentive fees or greater expense reimbursements or overhead allocations, all of which may contribute to this conflict of interest and create an incentive for the investment adviser to favor such other accounts. To seek to reduce potential conflicts of interest and to attempt to allocate such investment opportunities in a fair and equitable manner, the investment adviser has implemented allocation policies and procedures. These policies and procedures are intended to give all clients of the investment adviser, including the Fund(s), fair access to investment opportunities consistent with the requirements of organizational documents, investment strategies, applicable laws and regulations, and the fiduciary duties of the investment adviser.

Investments by Separate Investment Departments. The entities and individuals that provide investment-related services for the Fund and certain other Eaton Vance Investment Accounts (the “Eaton Vance Investment Department”) may be different from the entities and individuals that provide investment-related services to MS Investment Accounts (the “MS Investment Department” and, together with the Eaton Vance Investment Department, the “Investment Departments”). Although Morgan Stanley has implemented information barriers between the Investment Departments in accordance with internal policies and procedures, each Investment Department may engage in discussions and share information and resources with the other Investment Department on certain investment-related matters. A MS Investment Account could trade in advance of a Fund (and vice versa), might complete trades more quickly and efficiently than a Fund, and/or achieve different execution than a Fund on the same or similar investments made contemporaneously, even when the Investment Departments shared research and viewpoints that led to that investment decision. Any sharing of information or resources between the Investment Department servicing the Fund and the MS Investment Department may result, from time to time, in a Fund simultaneously or contemporaneously seeking to engage in the same or similar transactions as an account serviced by the other Investment Department and for which there are limited buyers or sellers on specific securities, which could result in less favorable execution for the Fund than such account.

Eaton Vance Worldwide Health Sciences Fund 28Prospectus dated January 1, 2022

voting rights it acquires or exercises, where the Fund (potentially together with Morgan Stanley) exceeds a certain ownership interest, or possesses certain degrees of voting or control or has other interests.

Morgan Stanley may be engaged to act as a financial advisor to a company in connection with the sale of such company, or subsidiaries or divisions thereof, may represent potential buyers of businesses through its mergers and acquisition activities and may provide lending and other related financing services in connection with such transactions. Morgan Stanley’s compensation for such activities is usually based upon realized consideration and is usually contingent, in substantial part, upon the closing of the transaction. Under these circumstances, a Fund may be precluded from participating in a transaction with or relating to the company being sold or participating in any financing activity related to merger or acquisition.

Additional Tax Information

The Fund expects to pay any required distributions annually, and intends to distribute any net realized capital gains (if any) annually. Distributions may not be paid if Fund (and/or Class) expenses exceed Fund income for the period. Different Classes of the Fund will generally distribute different amounts. It may also be necessary, in order to qualify for favorable tax treatment and to avoid any Fund-level tax, for the Fund to make a special income and/or capital gains distribution at the end of the calendar year.

Distributions of the Fund’s taxable investment income (other than qualified dividend income, which is described below) and net realized short-term capital gains generally will be taxed as ordinary income. Distributions of any net long-term capital gains (net gains from investments held for more than one year) generally will be taxed as long-term capital gains. Taxes on distributions of capital gains are determined by how long the Fund owned (or is treated as having owned) the investments that generated them, rather than how long a shareholder has owned his or her shares in the Fund. Distributions of investment income properly reported by the Fund as derived from “qualified dividend income” (as further described in the SAI) will be taxed in the hands of individuals at rates applicable to long-term capital gains provided holding period and other requirements are met at both the shareholder and Fund level. Over time, distributions by the Fund can generally be expected to include ordinary income, qualified dividend income and capital gain distributions taxable as long-term capital gains. A portion of the Fund’s income distributions may be eligible for the dividends-received deduction for corporations. The Fund’s distributions will be taxable as described above whether they are paid in cash or reinvested in additional shares.

Investors who purchase shares at a time when the Fund’s net asset value reflects gains that are either unrealized or realized but not distributed will pay the full price for the shares and then may receive some portion of the purchase price back as a taxable distribution. Certain distributions paid in January may be taxable to shareholders as if received on December 31 of the prior year. A redemption of Fund shares, including an exchange for shares of another fund, is generally a taxable transaction.

Eaton Vance Worldwide Health Sciences Fund 29Prospectus dated January 1, 2022

The Fund’s investments in foreign securities may be subject to foreign withholding taxes or other foreign taxes with respect to income (possibly including, in some cases, capital gains), which may decrease the Fund’s yield on such securities. These taxes may be reduced or eliminated under the terms of an applicable tax treaty. If eligible, the Fund may elect to allow Fund shareholders to include in gross income their pro rata share of qualified foreign income taxes paid by the Fund (even though such amounts are not received by the shareholders) and could allow Fund shareholders, provided certain requirements are met, to use their pro rata portion of such foreign income taxes as a foreign tax credit against their federal income taxes or, alternatively, for shareholders who itemize their deductions, to deduct their portion of the Fund’s foreign taxes paid in computing their taxable federal income. The Fund may qualify for and make this election in some, but not necessarily all of its taxable years. However, even if the Fund qualifies to make such election for any year, it may determine not to do so. In addition, investments in foreign securities or foreign currencies may increase or accelerate the Fund’s recognition of ordinary income and may affect the timing or amount of the Fund’s distributions.

The Fund may be required to withhold, for U.S. federal income tax purposes, a portion of the dividends, distributions and redemption proceeds payable to shareholders who fail to provide the Fund with their correct taxpayer identification number or make required certifications, or who have been notified by the Internal Revenue Service (“IRS”) that they are subject to backup withholding. Certain shareholders are exempt from backup withholding. Backup withholding is not an additional tax and any amount withheld may be credited against a shareholder’s U.S. federal income tax liability.

Certain foreign entities may be subject to a 30% withholding tax on ordinary dividend income paid under the Foreign Account Tax Compliance Act (“FATCA”). To avoid withholding, foreign financial institutions subject to FATCA must agree to disclose to the relevant revenue authorities certain information regarding their direct and indirect U.S. owners and other foreign entities must certify certain information regarding their direct and indirect U.S. owners to the Fund. In addition, the IRS and the Department of Treasury have issued proposed regulations providing that these withholding rules will not be applicable to the gross proceeds of share redemptions or capital gain dividends the Fund pays. For more detailed information regarding FATCA withholding and compliance, please refer to the SAI.

Shareholders should consult with their tax advisors concerning the applicability of federal, state, local and other taxes to an investment.
