Eaton Vance Domestic Equity Funds19Prospectus dated May 1, 2024

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 42% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of small-cap companies (the “80% Policy”). The portfolio managers consider small-cap companies to be companies having a market capitalization that falls (i) within or below the range of companies in the current Russell 2000® Index (the “Index”), or (ii) below the three-year average maximum market cap of companies in the Index as of December 31 of the three preceding years. The market capitalization range for the Index was approximately $10 million to $15.1 billion as of December 31, 2023. The average maximum market capitalization of companies in the Index as of the three year period ending December 31, 2023 was approximately $12.4 billion. Market capitalizations of companies within the Index are subject to change. With respect to 20% of its net assets, the Fund may also invest in companies that are larger than the capitalization ranges stated above. The Fund may also invest up to 25% of its total assets in foreign securities, some of which may be issued by companies domiciled in emerging market countries. As an alternative to holding foreign stocks directly, the Fund may invest in U.S. dollar-denominated securities of foreign companies that trade on U.S. exchanges or in the over-the-counter market (including depositary receipts, such as American Depositary Receipts (“ADRs”), which are either sponsored or unsponsored, and Global Depositary Receipts, that evidence ownership in underlying foreign stocks). 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 also invest in publicly traded real estate investment trusts (“REITs”).

Investment decisions for the Fund are made primarily on the basis of fundamental research. The portfolio managers utilize information provided by, and the expertise of, the investment adviser’s research staff in making investment decisions. The portfolio managers look for companies that, in their opinion, are high in quality or improving in quality. The portfolio managers take a long-term perspective when selecting companies and the quality focus typically leads them to companies benefitting from structural growth or structural change. Sought after company characteristics may include: a business model with identifiable competitive advantage(s)/barrier(s) to entry, a scalable market opportunity, a solid balance sheet, and a strong management team with a history of good capital allocation. The portfolio managers believe such companies typically exhibit high or improving returns on capital, strong free-cash-flow generation, and positive or inflecting earnings. The portfolio managers also employ a disciplined valuation framework in pursuit of attractive risk adjusted returns. The portfolio managers seek to manage investment risk by maintaining broad issuer and industry diversification among the Fund’s holdings, and by utilizing fundamental analysis of risk/return characteristics in securities selection. Securities may be sold if, in the opinion of the portfolio managers, the price moves above a fair level of valuation, the company’s fundamentals deteriorate, or to pursue more attractive investment opportunities.

Principal Risks

Market Risk. The value of investments held by the Fund may increase or decrease in response to social, economic, political, financial, public health crises or other disruptive events (whether real, expected or perceived) in the U.S. and global markets and include events such as war, natural disasters, epidemics and pandemics, terrorism, conflicts and social unrest. 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.

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.

Eaton Vance Domestic Equity Funds20Prospectus dated May 1, 2024

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

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 against a particular country or countries, organizations, entities and/or individuals. 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. Adverse changes in investment regulations, capital requirements or exchange controls could adversely affect the value of the Fund's investments. 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, including the political and economic risks of the underlying issuer's country and, in the case of depositary receipts traded on foreign markets, currency risk.

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 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.

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.

Industrials Sector Risk. To the extent a Fund invests a substantial portion of its assets in the industrials sector, factors that have an adverse impact on this sector may have a disproportionate impact on the Fund's performance. The industrials sector can be affected by government regulation, world events, supply and demand for specific products and services, commodity prices, exchange rates and economic conditions, technological developments, and liabilities for environmental damage, product liability claims, and general civil liabilities.

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.

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.

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.

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 and there is no guarantee that such decisions will produce the desired results or expected returns.

Eaton Vance Domestic Equity Funds21Prospectus dated May 1, 2024

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 and sub-adviser, if applicable, 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 one or more indexes intended to measure broad market performance. The Fund’s primary benchmark index was changed from the Russell 2000® Index to the Russell 3000® Index effective May 1, 2024 to comply with the regulation that requires the Fund’s primary benchmark to represent the overall applicable market. The additional index in the table provides a means to compare the Fund’s average annual returns to a benchmark that Boston Management and Research believes is representative of the Fund’s universe. 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.

Calendar year-by-year total return (Class A)

Year	2014	2015	2016	2017	2018	2019	2020	2021	2022	2023
Year Total Return	3.77%	-2.78%	19.32%	14.91%	-5.81%	27.54%	12.73%	21.18%	-15.53%	11.28%

For the ten years ended December 31, 2023, the highest quarterly total return for Class A was 24.20% for the quarter ended December 31, 2020, and the lowest quarterly return was -24.56% for the quarter ended March 31, 2020.

Eaton Vance Domestic Equity Funds22Prospectus dated May 1, 2024

Average Annual Total Return as of December 31, 2023	One Year	Five Years	Ten Years
Class A Return Before Taxes	5.42%	9.17%	7.29%
Class A Return After Taxes on Distributions	5.24%	7.93%	4.83%
Class A Return After Taxes on Distributions and Sale of Class A Shares	3.32%	7.21%	5.17%
Class C Return Before Taxes	9.46%	9.53%	7.22%
Class I Return Before Taxes	11.54%	10.63%	8.13%
Class R Return Before Taxes	11.03%	10.09%	7.61%
Russell 3000® Index (reflects no deductions for fees, expenses or taxes)	25.96%	15.15%	11.47%
Russell 2000® Index (reflects no deductions for fees, expenses or taxes)	16.93%	9.97%	7.15%

These returns reflect the maximum current sales charge for Class A (5.25%) and any applicable contingent deferred sales charge (“CDSC”) for Class C. Effective November 5, 2020, Class C shares automatically convert to Class A shares eight years after purchase. The average annual total returns listed for Class C reflect conversion to Class A shares after eight years. Prior to November 5, 2020, Class C shares automatically converted to Class A shares ten years after purchase. Investors cannot invest directly in an Index.

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.

Important Information Regarding Fund Shares

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. Adverse changes in investment regulations, capital requirements or exchange controls could adversely affect the value of the Fund's investments. 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 against a particular country or countries, organizations, entities and/or individuals, 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. Even if the Fund does not have significant investments in securities affected by sanctions, sanctions or the threat of sanctions may cause volatility in regional and global markets and may negatively impact the performance of various sectors and industries, as well as companies in other countries, including through global supply chain disruptions, increased inflationary pressures, and reduced economic activity, which could have a negative effect on the Fund’s performance. In addition, trade disputes may affect investor and consumer confidence and adversely affect financial markets and the broader economy, perhaps suddenly and to a significant degree. Events such as these and their impact on the Fund are difficult to predict.

In some non-U.S. securities markets, custody arrangements for securities provide significantly less protection than custody arrangements in U.S. securities markets, and prevailing custody and trade settlement practices (e.g., the requirement to pay for securities prior to receipt) expose the Fund to credit and other risks it does not have in the United States.

Eaton Vance Domestic Equity Funds25Prospectus dated May 1, 2024

The Fund needs a license to invest directly in securities traded in many non-U.S. securities markets. These licenses are often subject to limitations, including maximum investment amounts. Once a license is obtained, the Fund's ability to continue to invest directly is subject to the risk that the license may be terminated or suspended. In some circumstances, the receipt of a non-U.S. license by one of Eaton Vance's clients may prevent the Fund from obtaining a similar license. In addition, certain activities could cause the suspension or revocation of the Fund's license.

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 regarding the economic relationship between the UK and the EU. Market uncertainty remains 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. If one or more additional countries leave the EU or the EU dissolves, the world’s securities markets likely will be significantly disrupted.

In addition, the Holding Foreign Companies Accountable Act (the “HFCAA”) could cause securities of a foreign (non-U.S.) company, including American Depositary Receipts (“ADRs”), to be delisted from U.S. stock exchanges if the company does not allow the U.S. government to oversee the auditing of its financial information. Although the requirements of the HFCAA apply to securities of all foreign (non-U.S.) issuers, the SEC has thus far limited its enforcement efforts to securities of Chinese companies. If securities are delisted, the Fund’s ability to transact in such securities will be impaired, and the liquidity and market price of the securities may decline. The Fund may also need to seek other markets in which to transact in such securities, which could increase the Fund’s costs.

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 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. Unless otherwise stated in the Fund Summaries, such investments are not subject to any stated limitation on investing in foreign securities.

Emerging Markets Investments. The risks of foreign investments can be more significant in emerging markets. Unless otherwise provided in the Fund’s principal investment strategies, an emerging market country is any country determined by the investment adviser to have an emerging market economy, considering factors such as the country’s political and economic stability, and the development of its financial and capital 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. Emerging markets investments may also include investments through complex structures that may lack transparency.

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

Eaton Vance Domestic Equity Funds26Prospectus dated May 1, 2024

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.

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 may subject the Fund to heightened risk of loss. 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 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.

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.

Eaton Vance Domestic Equity Funds27Prospectus dated May 1, 2024

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 most derivatives to be margined and/or cleared and traded on an exchange, expand entity registration requirements, impose business conduct requirements on counterparties, and impose other regulatory requirements that impact derivatives markets. The SEC adopted Rule 18f-4 under the 1940 Act, which applies to the Fund’s use of derivative investments and certain financing transactions. Among other things, Rule 18f-4 requires certain funds that invest in derivative instruments beyond a specified limited amount (generally greater than 10% of a fund's net assets) to apply a value-at-risk based limit to their use of certain derivative instruments and financing transactions and to adopt and implement a derivatives risk management program. To the extent a Fund uses derivative instruments (excluding certain currency and interest rate hedging transactions) in a limited amount (up to 10% of a Fund's net assets), it will not be subject to the full requirements of Rule 18f-4. In addition, to the extent that the Fund enters into reverse repurchase agreements or similar financing transactions, the Fund may elect to either treat all of its reverse repurchase agreements or similar financing transactions as derivatives transactions for purposes of Rule 18f-4 or comply (with respect to reverse repurchase agreements or similar financing transactions) with the asset segregation requirements under Section 18 of the 1940 Act. The implementation of these requirements or 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 fully predict the effects of any governmental regulation of the derivatives markets, and there can be no assurance that any government regulation will not adversely affect the Fund’s performance or ability to achieve its investment objective(s). Regulations adopted by federal banking regulators under the Dodd-Frank Act require that certain qualified financial contracts (“QFCs”) with counterparties that are part of U.S. or foreign global systemically important banking organizations be amended to include contractual restrictions on close-out and cross-default rights. QFCs include, but are not limited to, securities contracts, commodities contracts, forward contracts, repurchase agreements, securities lending agreements and swaps agreements, as well as related master agreements, security agreements, credit enhancements, and reimbursement obligations. If a covered counterparty of a Fund or certain of the covered counterparty’s affiliates were to become subject to certain insolvency proceedings, a Fund may be temporarily unable to exercise certain default rights, and the QFC may be transferred to another entity. In addition, under the rule, a Fund is permitted to invest in a security on a when-issued or forward-settling basis, or with a non-standard settlement cycle, and the transaction will be deemed not to involve a senior security under the 1940 Act, provided that (i) the Fund intends to physically settle the transaction and (ii) the transaction will settle within 35 days of its trade date (the “Delayed-Settlement Securities Provision”). A Fund may otherwise engage in such transactions that do not meet the conditions of the Delayed-Settlement Securities Provision so long as the Fund treats any such transaction as a “derivatives transaction” for purposes of compliance with the rule. Furthermore, under the rule, a Fund will be permitted to enter into an unfunded commitment agreement, and such unfunded commitment agreement will not be subject to the asset coverage requirements under the 1940 Act, if the Fund reasonably believes, at the time it enters into such agreement, that it will have sufficient cash and cash equivalents to meet its obligations with respect to all such agreements as they come due. These requirements may impact a Fund’s credit and counterparty risks.

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.

Eaton Vance Domestic Equity Funds28Prospectus dated May 1, 2024

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.

Swaptions. Swaptions are options giving the option owner the right (but not the obligation) to enter into a swap agreement as buyer or seller, or to extend, shorten, cancel or otherwise modify an existing swap agreement at a future date on specified terms.

Depending on the terms of the particular swaption, the Fund generally will incur a greater degree of risk when it writes a swaption than it will incur when it purchases a swaption. When the Fund purchases a swaption, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. When the Fund writes a swaption, upon exercise of the option, the Fund will become obligated according to the terms of the underlying swap agreement.

Put option spreads involve purchasing put options at a specific strike price while also selling the same number of puts at a lower strike price. By doing so, the Fund can lower the net cost of its market hedging activities, since the premiums received from selling put options will offset, in part, the premiums paid to purchase the put options. Although less expensive than buying a standalone put option, buying a put option spread will expose the Fund to incremental loss if the value of the applicable instrument at contract expiration is below the exercise price of the put option sold.

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.

Eaton Vance Domestic Equity Funds29Prospectus dated May 1, 2024

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.

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.

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. 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.

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 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.

Information Technology Sector Risk. If the Growth Fund concentrates investments in the information technology sector, the value of Fund shares may be particularly impacted by events that adversely affect the information technology sector, such as rapid changes in technology product cycles, competition for the services of qualified personnel and government regulation. The products of information technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction and unpredictable changes in growth rates. Companies in the information technology sector also can be heavily dependent on patent protection and the expiration of patents may adversely affect the profitability of these companies. As a result, the value of shares may fluctuate more than that of a fund that does not concentrate in companies in the technology sector.

Industrials Sector Risk. To the extent the Small-Cap Fund invests a substantial portion of its assets in the industrials sector, factors that have an adverse impact on this sector may have a disproportionate impact on the Fund's performance. The industrials sector can be affected by government regulation, world events, commodity prices, exchange rates and economic conditions, and liabilities for environmental damage, product liability claims, and general civil liabilities. Companies in the industrials sector may also be adversely affected by supply and demand changes related to their specific products or services and industrials sector products in general. The products of industrial sector companies may face obsolescence due to rapid technological developments and frequent new product introduction.

Real Estate Investments. Companies primarily engaged in the real estate industry and other real estate-related investments may include publicly traded 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 may be small to medium-sized companies, and may include equity REITs and mortgage REITs. The value of a

Eaton Vance Domestic Equity Funds30Prospectus dated May 1, 2024

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.

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; the management skill and creditworthiness of the issuer; local, state, national or international economic conditions and real estate market conditions (such as oversupply of real estate for rent or sale or vacancies, potentially for extended periods); reduced demand for commercial and office space as well as increased maintenance or tenant improvement costs and costs to convert properties for other uses; and default risk and credit quality of tenants and borrowers. 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. Real estate income and values may also be greatly affected by demographic trends, such as population shifts or changing tastes, preferences (such as remote work arrangements), and values.

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.

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 use of leverage may cause the Fund to maintain liquid assets or liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations. 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.

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. 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 countries and regulatory bodies may use negative interest rates as a monetary policy tool to encourage economic growth during periods of deflation. In a negative interest rate environment, debt instruments may trade at negative yields, which means the purchaser of the instrument may receive at maturity less than the total amount invested. Changes in governmental policy, including changes in central bank monetary policy, could cause interest rates to rise rapidly, or cause investors to expect a rapid rise in interest rates. This could lead to heightened levels of interest rate, volatility and liquidity risks for the fixed income markets generally and could have a substantial and immediate effect on the values of the Fund's investments.

LIBOR. The London Interbank Offered Rate or LIBOR was the average offered rate for various maturities of short-term loans between major international banks who were members of the British Bankers Association. It historically was 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, ceased publishing certain LIBOR settings on December 31, 2021, and ceased publishing the remaining LIBOR settings on June 30, 2023. In addition, global regulators have

Eaton Vance Domestic Equity Funds31Prospectus dated May 1, 2024

announced that, with limited exceptions, no new LIBOR-based contracts should be entered into after 2021. Market participants have transitioned or are in the process of transitioning to the use of alternative reference or benchmark rates.

The impact of the transition away from LIBOR on certain debt securities, derivatives and other financial instruments that utilize LIBOR remains uncertain. The transition away from LIBOR and the use of replacement rates may adversely affect transactions that used LIBOR as a reference rate, financial institutions, funds and other market participants that engaged in such transactions, and the financial markets generally. The transition may result in changes 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.

In planning for the transition away from LIBOR, various financial industry groups encountered 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 the Fund to enter into hedging transactions against instruments tied to alternative reference rates until a market for such hedging transactions develops.

Additionally, while many LIBOR-based instruments contemplated 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 LIBOR-based instruments had such fallback provisions. Federal legislation has been enacted in the U.S. to assist with the transition away from LIBOR to new reference rates for instruments known as “tough legacy” contracts. Although there are ongoing efforts among global government entities and other organizations to address transition-related 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. Furthermore, the risks associated with the 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.

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. The market price of a fixed-income investment can decline due to market-related factors, including rising interest rates and widening credit spreads, rising inflation, or decreased liquidity due to, for example, market uncertainty about the value of a fixed-income investment (or class of fixed income investments).

Convertible Securities. A convertible security is a bond, debenture, note, preferred security, or other security that entitles the holder to acquire common stock or other equity securities of the same or a different issuer. A convertible security entitles the holder to receive interest paid or accrued or dividends paid until the convertible security matures or is redeemed, converted or exchanged. Before conversion, convertible securities have characteristics similar to nonconvertible income securities.

Eaton Vance Domestic Equity Funds32Prospectus dated May 1, 2024

Holders of convertible securities generally have a claim on the assets of the issuer prior to the common stockholders but may be subordinated to other debt securities of the same issuer. Certain convertible debt securities may provide a put option to the holder, which entitles the holder to cause the securities to be redeemed by the issuer at a premium over the stated principal amount of the debt securities under certain circumstances. Certain convertible securities may include loss absorption characteristics that make the securities more debt-like. This is particularly true of convertible securities issued by companies in the financial services sector.

The value of a convertible security may be influenced by changes in interest rates, with investment value declining as interest rates increase and increasing as interest rates decline. The credit standing of the issuer and other factors also may have an effect on the convertible security’s investment value. A convertible security may be subject to redemption at the option of the issuer at a price established in the convertible security’s governing instrument.

Hybrid Securities. Hybrid securities generally possess certain characteristics of both equity and debt securities. These securities may at times behave more like equity than debt, or vice versa. Preferred stocks, convertible securities, trust preferred securities and certain debt obligations are types of hybrid securities. The investment adviser has sole discretion to determine whether an investment has hybrid characteristics and generally will consider the instrument’s preference over the issuer’s common shares, the term of the instrument at the time of issuance, and/or the tax character of the instrument’s distributions. Hybrid securities generally do not have voting rights or have limited voting rights. Hybrid securities may be subject to redemption at the option of the issuer at a predetermined price. Hybrid securities may pay a fixed or variable rate of interest or dividends. The prices and yields of nonconvertible hybrid securities generally move with changes in interest rates and the issuer’s credit quality, similar to the factors affecting debt securities. If the issuer of a hybrid security experiences financial difficulties, the value of such security may be adversely affected similar to the issuer’s outstanding common stock or subordinated debt instruments.

Because hybrid securities have both debt and equity characteristics, their values vary in response to many factors, including issuer-specific events, credit spreads and, for convertible securities, factors affecting the securities into which they convert. Trust preferred securities are issued by a special purpose trust that holds the subordinated debt of a company and, as such, are subject to the risks associated with such debt obligation.

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.

ReFlow Liquidity Program. Large-Cap Value Fund may participate in the ReFlow liquidity program, which is designed to provide an alternative liquidity source for mutual funds experiencing net redemptions of their shares. Pursuant to the program, ReFlow Fund, LLC (“ReFlow”) provides participating mutual funds with a source of cash to meet net shareholder redemptions by standing ready each business day to purchase fund shares up to the value of the net shares redeemed by other shareholders that are to settle the next business day. Following purchases of fund shares, ReFlow then generally redeems those shares when the fund experiences net sales, at the end of a maximum holding period determined by ReFlow (currently 8 days) or at other times at ReFlow’s discretion. While ReFlow holds fund shares, it will have the same rights and privileges with respect to those shares as any other shareholder. For use of the ReFlow service, a fund pays a fee to ReFlow each time it purchases fund shares, calculated by applying to the purchase amount a fee rate determined through an automated daily auction among participating mutual funds. The current minimum fee rate is 0.14% of the value of the fund shares purchased by ReFlow although the fund may submit a bid at a higher fee rate if it determines that doing so is in the best interest of fund shareholders. Such fee is allocated among a fund’s share classes based on relative net assets. ReFlow’s purchases of fund shares through the liquidity program are made on an investment-blind basis without regard to the fund’s objective, policies or anticipated performance. In accordance with federal securities laws, ReFlow is prohibited from acquiring more than 3% of the outstanding voting securities of a fund. ReFlow purchases the Fund’s lowest-cost share class at net asset value and will not be subject to any investment minimum applicable to such shares. ReFlow will periodically redeem its entire share position in the Fund and request that such redemption be met in kind in accordance with the Fund’s redemption-in-kind policies described under “Redeeming Shares” below. Investments in the Fund by ReFlow in connection with the ReFlow liquidity program are not subject to the two round-trips

Eaton Vance Domestic Equity Funds33Prospectus dated May 1, 2024

within 90 days limitation described in “Restrictions on Excessive Trading and Market Timing” below. The investment adviser believes that the program assists in stabilizing the Fund’s net assets to the benefit of the Fund and its shareholders. To the extent the Fund’s net assets do not decline, the investment adviser may also benefit.

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. See “Lower Rated Investments.” 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. If an instrument is rated differently by two or more rating agencies, the highest rating will be used for any Fund rating restrictions.

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 are speculative because of increased credit risk relative to other fixed income investments. 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. Lower rated investments are considered primarily speculative with respect to the issuer’s capacity to pay interest and repay principal.

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.

Smaller Companies. Dividend Builder Fund and Small-Cap Fund may invest in 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. 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 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.

Eaton Vance Domestic Equity Funds34Prospectus dated May 1, 2024

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.

Pooled Investment Vehicles. The Fund may invest in pooled investment vehicles to the extent permitted by the 1940 Act, and the rules, regulations and interpretations thereunder. 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 certain 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% of the average net assets of the Fund, 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. Investments in a pooled investment vehicle will count towards a Fund's 80% Policy if the vehicle invests at least 80% of its net assets in the type of securities included in the Fund's 80% Policy.

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.

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

Eaton Vance Domestic Equity Funds35Prospectus dated May 1, 2024

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.

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.

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.

Cash and Money Market Instruments; Temporary Defensive Positions. 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, including for temporary defensive purposes, the Fund may invest up to 100% of its assets in cash or money market instruments, which may be inconsistent with its investment objective(s) and other policies, and as such, the Fund may not achieve its investment objective(s) during this period.

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.

Issuer Non-Diversification. Growth Fund is a non-diversified Fund. A “non-diversified” fund can invest more of its assets in a smaller number of issuers than diversified funds. Focusing investments in a smaller number of issuers could result in greater potential losses than for funds investing in a broader variety of issuers, and the value of a non-diversified fund's shares may be more volatile than the values of shares of more diversified funds. However, the Fund intends to qualify as a regulated investment company under the Code. This requires the Fund to limit its investments so that, at the end of each fiscal quarter, at least 50% of the Fund’s total assets are invested in (i) cash and cash items, U.S. Government securities and securities of other regulated investment companies, and (ii) single issuers that are less than 5% of the total assets of the Fund and not more than 10% of the outstanding voting shares of the issuer. In addition, at the end of each fiscal quarter, not more than 25% of the value of the Fund’s total assets can be invested, including through corporations in which the Fund owns a 20% or more voting stock interest, in the securities (other than those of the U.S. Government or other regulated investment companies) of any one issuer or of two or more issuers that the Fund controls and that are engaged in the same, similar, or related trades or businesses.

Converting to Hub and Spoke Structure. Each Fund may invest all of its 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.

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,

Eaton Vance Domestic Equity Funds36Prospectus dated May 1, 2024

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. Similar types of cybersecurity risks also are present for issuers of securities in which the Fund invests, which could have material adverse consequences for those issuers and result in a decline in the market price of their securities. Furthermore, as a result of cyber attacks, technological disruptions, malfunctions or failures, an exchange or market may close or suspend trading in specific securities or the entire market, which could prevent the Fund from, among other things, buying or selling the Fund or accurately pricing its securities. 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.

Geopolitical Risk. The increasing interconnectivity between global economies and markets increases the likelihood that events or conditions in one country, region, sector, industry or market or, with respect to one company, may adversely impact issuers in a different country, region, sector, industry or market. For example, adverse developments in the banking or financial services sector could impact companies operating in various sectors or industries and adversely impact the Fund’s investments. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, health emergencies (such as epidemics and pandemics), terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, health emergencies, social and political discord, war, banking or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. Other financial, economic and other global market and social developments or disruptions may result in similar adverse circumstances, and it is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects (which may last for extended periods).

Such global events may negatively impact broad segments of businesses and populations, cause a significant negative impact on the performance of the Fund’s investments, adversely affect and increase the volatility of the Fund’s share price, and/or exacerbate pre-existing political, social and economic risks to the Fund. The Fund’s operations may be interrupted and any such event(s) could have a significant adverse impact on the value and risk profile of the Fund’s portfolio. There is a risk that you may lose money by investing in the Fund.

Recent Market Conditions. The outbreak of COVID-19 and efforts to contain its spread 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, and the effects of other infectious illness outbreaks, epidemics or pandemics, may be short term or may continue for an extended period of time. Health crises caused by outbreaks of disease may exacerbate other pre-existing

Eaton Vance Domestic Equity Funds37Prospectus dated May 1, 2024

political, social and economic risks and disrupt normal market conditions and operations. 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 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 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. The effects of the outbreak may also cause issuers of securities held by the Fund to reduce, delay or eliminate previously anticipated dividend payments, which may adversely affect the Fund’s distribution rate.

General. Dividend Builder Fund's, Large-Cap Value Fund's and Small-Cap Fund's 80% Policy will not be changed unless shareholders are given at least 60 days’ advance written notice of the change. The Fund's investment objective may not be changed without shareholder approval. Certain other policies may be changed without shareholder 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.

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. In addition, 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 and the investment adviser may be restricted in its ability to cause the Fund to buy or sell securities of an issuer for substantial periods of time when the Fund otherwise could realize profit or avoid loss. This may adversely affect the Fund's flexibility with respect to buying or selling securities and may impair the Fund's liquidity.

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

Valuing Shares

You may buy or sell (redeem) shares of each Fund at the NAV next determined for the class after receipt of your order in good order, plus any applicable sales charge. Each Fund’s NAV is determined as of the close of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. Eastern Time) on each day that the NYSE is open for business (typically Monday through Friday) (the “Pricing Time”). Each Fund is closed for business and will not issue a NAV on the following business holidays and any other business day that the NYSE is closed: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. On holidays or other days when the NYSE is closed, the NAV is generally not calculated and a Fund generally does not transact purchase or redemption requests. However, on those days, the value of a Fund’s assets may be affected to the extent that the Fund holds foreign securities that trade on foreign markets that are open. In addition, trading of securities that are primarily listed on foreign exchanges may take place on weekends and other days when a Fund does not price its interests or transact purchase or redemption requests.

Eaton Vance Domestic Equity Funds40Prospectus dated May 1, 2024

If the NYSE is closed due to inclement weather, technology problems or any other reason on a day it would normally be open for business, or the NYSE has an unscheduled early closing on a day it has opened for business, a Fund reserves the right to treat such day as a business day and accept purchase and redemption orders until, and calculate its NAV as of, the normally scheduled close of regular trading on the NYSE for that day, so long as its investment adviser believes there generally remains an adequate market to obtain reliable and accurate market quotations. If market quotations, official closing prices, or information furnished by a pricing service are not readily available or, in the investment adviser’s opinion, are deemed unreliable for a security, then that security will be fair valued in good faith by the investment adviser in accordance with applicable fair value pricing policies and in accordance with applicable law. A Fund may elect to remain open and price its shares on days when the NYSE is closed but the primary securities markets on which the Fund’s securities trade remain open. To the extent, if any, that a Fund invests in securities primarily listed on foreign exchanges, the value of the Fund’s portfolio securities may change on days when you will not be able to purchase or sell your shares. 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 NYSE 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, as valuation designee, the daily valuation of such investments. Pursuant to the Procedures, securities and other investments held by a Fund for which market quotations are readily available 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.

Pursuant to the Procedures, if market quotations are not readily available (or otherwise not reliable) for a particular investment, the fair value of the investment will be determined by the investment adviser, as valuation designee. A market quotation is readily available only when that quotation is a quoted price (unadjusted) in active markets for identical investments that a Fund can access at the measurement date, provided that a quotation will not be readily available if it is not reliable. As such, a Fund will 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 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 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 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

Eaton Vance Domestic Equity Funds41Prospectus dated May 1, 2024

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 NYSE (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 Eaton Vance 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.

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. 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). The Class A minimum initial investment amount is waived for permitted exchanges of shares of a registered closed-end fund operated as an “interval fund” that continuously offers its shares at NAV and that is advised or sponsored by Eaton Vance or its affiliates.

Class I Shares

Your initial investment must be at least $1,000,000, 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) and the ReFlow Liquidity Program. The minimum initial investment also is waived for: (i) permitted exchanges, including exchanges of shares of a registered closed-end fund operated as an “interval fund” that continuously offers its shares at NAV and that is advised or sponsored by Eaton Vance or its affiliates; (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.

Class R6 Shares

Class R6 shares are offered to employer sponsored retirement plans held in plan level or omnibus accounts; endowments; foundations; local, city, and state governmental institutions; corporations; charitable trusts; trust companies; private banks and their affiliates; and insurance companies; investors who purchase shares through asset-based fee programs of certain financial intermediaries that have entered into an agreement with the Fund’s principal underwriter to offer Class R6 shares through such programs; and investment companies. In order to offer Class R6 shares to investors other than employer sponsored retirement plans, a financial intermediary must enter into a written agreement with the Fund’s principal underwriter to offer such shares.

There is no initial investment minimum for: employer sponsored retirement plans; private banks and their affiliates; investors who purchase shares through asset-based fee programs as described above, provided the aggregate value of such program’s assets under management invested in Eaton Vance funds is at least $5,000,000; and investment companies sponsored by the Eaton Vance organization. For all other eligible investors, the initial investment must be at least $5,000,000. Subsequent investments of any amount may be made at any time. Please call 1-800-262-1122 Monday through Friday, 8:30 a.m. to 5:30 p.m. (Eastern Time) for further information.

Class R6 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 NYSE). 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 and Risk of Escheatment. In accordance with state “unclaimed property” laws, your Fund shares may legally be considered abandoned and required to be transferred to the relevant state (also known as “escheatment”) under various circumstances. These circumstances, which vary by state, can include inactivity (e.g., no owner-initiated contact for a certain period), returned mail (e.g., when mail sent to a shareholder is returned by the post office as undeliverable), uncashed checks or a combination of these. An incorrect address may cause a shareholder’s account statements and other mailings to be returned to the Fund or your financial intermediary. Since states’ statutory requirements regarding inactivity differ, it is important to regularly contact your financial intermediary or the Fund’s transfer agent. The process described above, and the application of state escheatment laws, may vary by state and/or depending on how shareholders hold their shares in the Fund.

It is your responsibility to ensure that you maintain a valid mailing address for your account, keep your account active by contacting your financial intermediary or the Fund’s transfer agent (e.g., by mail or telephone), and promptly cash all checks for dividends, capital gains and redemptions. Neither the Fund nor the investment adviser(s) will be liable to shareholders or their representatives for good faith compliance with escheatment laws.

For more information, please see https://funds.eatonvance.com/mutual-funds-and-abandoned-property.php or please contact us at 1-800-262-1122.

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

Eaton Vance Domestic Equity Funds43Prospectus dated May 1, 2024

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 is 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, acting in its capacity as the Fund’s sub-transfer agent, 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

·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

Eaton Vance Domestic Equity Funds44Prospectus dated May 1, 2024

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 5.25%. 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.

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.

Class R6 shares are offered at net asset value to employer sponsored retirement plans and certain other investors as described under “Class R6 Shares” above. Class R6 shares are not subject to distribution fees, service fees or sub-accounting/recordkeeping or similar fees paid to financial intermediaries.

Eaton Vance Domestic Equity Funds45Prospectus dated May 1, 2024

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, provided that no such compensation is paid with respect to Class R6 shares. 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	5.25%	5.54%	4.75%
$50,000 but less than $100,000	4.50%	4.71%	4.00%
$100,000 but less than $250,000	3.50%	3.63%	3.00%
$250,000 but less than $500,000	2.50%	2.56%	2.00%
$500,000 but less than $1,000,000	2.00%	2.04%	1.50%
$1,000,000 or more	0.00**	0.00**	TIERED**

*Because the offering price per share, which includes the front-end sales charge, 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 $4 million; plus 0.50% on amounts of $4 million but less than $15 million; plus 0.25% on amounts of $15 million or more. A CDSC of 1.00% will be imposed on such investments (as described below) in the event of redemptions within 12 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 is $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 Domestic Equity Funds46Prospectus dated May 1, 2024

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 12 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, Class C and Class R 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. 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

Eaton Vance Domestic Equity Funds47Prospectus dated May 1, 2024

R shares 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 1.00% 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 Class A shares, the principal underwriter receives the Class A distribution and service fees and generally the financial intermediary receives such fees immediately after the sale. After the sale of Class C shares, the principal underwriter generally receives the Class C service fees for one year, thereafter financial intermediaries generally receive such fees. 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 C shares by certain employer sponsored retirement plans, the financial intermediary receives the above described service fees from the principal underwriter immediately after the sale. Such amounts are generally paid to financial intermediaries by the principal underwriter based on the value of shares sold by such financial intermediaries for shareholder servicing performed by such intermediaries. 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.

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 NYSE (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 Domestic Equity Funds49Prospectus dated May 1, 2024

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 a Fund and all future distributions will be reinvested. For accounts held directly with a Fund’s transfer agent for which the shareholder has elected to receive distributions via check, any distribution (dividend or capital gain) under $10.00 is automatically reinvested in additional shares regardless of your elected distribution option.

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 Domestic Equity Funds50Prospectus dated May 1, 2024

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. Exchanges are made at net asset value. If your shares are subject to a CDSC (or in the case of an Eaton Vance “interval fund,” are subject to an early withdrawal charge), the CDSC or early withdrawal charge will continue to apply to your new shares at the same CDSC or early withdrawal charge (as applicable) rate. For purposes of the CDSC or early withdrawal charge (as applicable), 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 or early withdrawal charge (in the case of an exchange from an Eaton Vance “interval fund”) 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.

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

Eaton Vance Domestic Equity Funds51Prospectus dated May 1, 2024

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 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 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 Eaton Vance Corp. (“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 Domestic Equity Funds52Prospectus dated May 1, 2024

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 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.

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.

Payments to Broker-Dealers and Other Financial Intermediaries. The investment adviser and/or Eaton Vance Distributors, Inc. (“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

Eaton Vance Domestic Equity Funds53Prospectus dated May 1, 2024

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.

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 the 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

Dividend Builder Fund expects to pay distributions monthly, Large-Cap Value Fund expects to pay distributions quarterly, and Growth Fund and Small-Cap Fund expect to pay distributions 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. Each Fund intends to distribute any net realized capital gains, if any, annually. 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. Each Fund expects to send shareholders a statement each February showing the tax status of all distributions.

Distributions of a Fund’s investment income (other than “qualified dividend income” as described below) and net realized short-term capital gains generally will be taxed as ordinary income. Distributions of 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 a 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 the 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 regardless of whether they are paid in cash or reinvested in additional shares. As long as return of capital does not exceed a shareholder’s cost basis in its shares, it generally will not be taxable to the shareholder but will reduce the cost basis of the shareholder’s shares and result in a higher reported capital gain or a lower reported capital loss on a subsequent taxable disposition of such shares.

Eaton Vance Domestic Equity Funds54Prospectus dated May 1, 2024

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 “net investment income” and the excess of modified adjusted gross income over certain threshold amounts. Net investment income includes, among other things, interest, dividends 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.

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 a 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 a 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.

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 a Fund. In addition, the IRS and the Department of the 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 a 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 U.S. federal, state, local and other taxes, including non-U.S. 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.

It is the client’s responsibility to notify Merrill at the time of purchase or sale of any relationship or other facts that qualify the transaction for a waiver or discount. A Merrill representative may ask for reasonable documentation of such facts and Merrill may condition the granting of a waiver or discount on the timely receipt of such documentation.

Additional information on waivers and discounts is available in the Merrill Sales Load Waiver and Discounts Supplement (the “Merrill SLWD Supplement”) and in the Mutual Fund Investing at Merrill pamphlet at ml.com/funds.

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 January 1, 2024, 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. 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.

Sales Charge Waivers

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

·Associates of Edward Jones and its affiliates and other accounts 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.

·Shares purchased from the proceeds of redeemed shares of the same fund family so long as the following conditions are met: the proceeds are from the sale of shares within 60 days of the purchase, the sale and purchase are made from a share class that charges a front load and one of the following:

·The redemption and repurchase occur in the same account.

Eaton Vance Domestic Equity Funds74Prospectus dated May 1, 2024

·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 CDSC due to the fund company, 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.

·Purchases of Class 529-A shares through a rollover from either another education savings plan or a security used for qualified distributions.

·Purchases of Class 529 shares made for recontribution of refunded amounts.

Contingent Deferred Sales Charge (“CDSC”) Waivers

·The death or disability of the shareholder.

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