EXAMPLE

This Example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. Class C shares generally convert automatically to Class A shares after 8 years. The information presented in the Example for Class C reflects the conversion of Class C shares to Class A shares after 8 years. See “Class C Shares” in the “Choosing a Share Class” section of the prospectus for more information. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may mean higher taxes if you are investing in a taxable account. These costs are not reflected in annual fund operating expenses or in the expense example, and can affect the fund's performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 106% of the average value of its portfolio.

Principal Investment Strategies

Main investments. Under normal circumstances, the fund will invest at least 80% of its net assets, plus the amount of any borrowing for investment purposes (calculated at the time of any investment), in equity securities of real estate investment trusts (REITs) and real estate companies. A company is considered to be a real estate company if, in the opinion of portfolio management, at least 50% of its revenues or 50% of the market value of its assets at the time of purchase are attributed to the ownership, construction, management or sale of real estate. The fund may invest without limitation in securities of companies engaged principally in the real estate industry.

Due to regulatory changes, effective June 11, 2026, the fund will replace the 80% investment policy and related disclosures set forth in this prospectus. Specifically, effective June 11, 2026, under normal circumstances, the fund invests at least 80% of net assets, plus the amount of any borrowings for investment purposes, in equity securities of real estate investment trusts (REITs) and real estate companies.

Management process. In choosing securities, portfolio management uses a combination of two analytical disciplines:

Top-down research. Portfolio management analyzes market-wide investment conditions to arrive at the fund’s weighting across investment sectors, such as office, industrial, retail, hospitality and residential apartment real estate sectors.

Bottom-up research. Portfolio management analyzes characteristics and investment prospects of a particular security relative to others to actively manage the fund’s exposure to individual securities within each sector. Disciplined valuation analysis drives this decision-making process, guiding portfolio management to invest in securities they believe can provide superior returns over the long-term, and to sell those that they believe no longer represent the strongest prospects. In its analysis, portfolio management primarily considers a company's balance sheet, the quality and geography of the property, the management team, liquidity, and a number of environmental, social and governance (ESG) considerations, each of which can impact an investment's risks and expected returns. Lastly, portfolio management considers the real estate securities markets in general when making investment decisions.

Securities lending. The fund may lend securities (up to one-third of total assets) to approved institutions, such as registered broker-dealers, pooled investment vehicles, banks and other financial institutions. In connection with such loans, the fund receives liquid collateral in an amount that is based on the type and value of the securities being lent, with riskier securities generally requiring higher levels of collateral.

Active trading. The fund may trade securities actively and this may lead to high portfolio turnover.

Main Risks

There are several risk factors that could hurt the fund’s performance, cause you to lose money or cause the fund’s performance to trail that of other investments. The fund may not achieve its investment objective, and is not intended to be a complete investment program. An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.

Stock market risk. When stock prices fall, you should expect the value of your investment to fall as well. Stock prices can be hurt by poor management on the part of the stock’s issuer, shrinking product demand and other business risks. These may affect single companies as well as groups of companies. The market as a whole may not favor the types of investments the fund makes, which could adversely affect a stock’s price, regardless of how well the company performs, or the fund’s ability to sell a stock at an attractive price. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. Events in the US and global financial markets, including actions taken by the US Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility which could negatively affect performance. High market volatility may also result from significant shifts in momentum of one or more specific stocks due to unusual increases or decreases in

trading activity. Momentum can change quickly, and securities subject to shifts in momentum may be more volatile than the market as a whole and returns on such securities may drop precipitously. To the extent that the fund invests in a particular geographic region, capitalization or sector, the fund’s performance may be affected by the general performance of that region, capitalization or sector.

Market disruption risk. Economies and financial markets throughout the world have become increasingly interconnected, which has increased the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. This includes reliance on global supply chains that are susceptible to disruptions resulting from, among other things, war and other armed conflicts, tariffs, extreme weather events, and natural disasters. Such supply chain disruptions can lead to, and have led to, economic and market disruptions that have far-reaching effects on financial markets worldwide. The value of the fund’s investments may be negatively affected by adverse changes in overall economic or market conditions, such as the level of economic activity and productivity, unemployment and labor force participation rates, inflation or deflation (and expectations for inflation or deflation), interest rates, demand and supply for particular products or resources including labor, debt levels and credit ratings, and trade policies, among other factors. Such adverse conditions may contribute to an overall economic contraction across entire economies or markets, which may negatively impact the profitability of issuers operating in those economies or markets. In addition, geopolitical and other globally interconnected occurrences, including war, terrorism, economic uncertainty or financial crises, contagion, tariffs and trade disputes, government debt crises (including defaults or downgrades) or uncertainty about government debt payments, government shutdowns, public health crises, natural disasters, supply chain disruptions, climate change and related events or conditions, have led, and in the future may lead, to disruptions in the US and world economies and markets, which may increase financial market volatility and have significant adverse direct or indirect effects on the fund and its investments. Adverse market conditions or disruptions could cause the fund to lose money, experience significant redemptions, and encounter operational difficulties. Although multiple asset classes may be affected by adverse market conditions or a particular market disruption, the duration and effects may not be the same for all types of assets.

conflicts and related sanctions can adversely affect regional and global energy, commodities, financial and other markets and thus could affect the value of the fund's investments. The extent and duration of any military conflict, related sanctions and resulting economic and market disruptions are impossible to predict, but could be substantial.

Other market disruption events include pandemic spread of viruses, such as the novel coronavirus known as COVID-19, which have caused significant uncertainty, market volatility, decreased economic and other activity, increased government activity, including economic stimulus measures, and supply chain disruptions. While COVID-19 is no longer considered to be a public health emergency, the fund and its investments may be adversely affected by lingering effects of this virus or future pandemic spread of viruses.

In addition, markets are becoming increasingly susceptible to disruption events resulting from the use of new and emerging technologies to engage in cyber-attacks or to take over the Web sites and/or social media accounts of companies, governmental entities or public officials, or to otherwise pose as or impersonate such, which then may be used to disseminate false or misleading information that can cause volatility in financial markets or for the securities of a particular company, group of companies, industry or other class of assets.

Adverse market conditions or particular market disruptions, such as those discussed above, may magnify the impact of each of the other risks described in this “MAIN RISKS” section and may increase volatility in one or more markets in which the fund invests leading to the potential for greater losses for the fund.

Concentration risk. Any fund that concentrates in a particular segment of the market will generally be more volatile than a fund that invests more broadly. Any market price movements, regulatory or technological changes, or economic conditions affecting the particular segment of the market in which the fund concentrates may have a significant impact on the fund’s performance.

losses from casualty or condemnation. In addition, real estate values have been subject to substantial fluctuations and declines on a local, regional and national basis in the past and may continue to be in the future. During periods of rising interest rates, real estate securities may lose appeal for investors who may be able to obtain higher yields from other income-producing investments. Rising interest rates may also mean that financing for property purchases and improvements is more costly and difficult to obtain. In addition, many real estate companies, including REITs, utilize leverage which increases investment risk. Political or regulatory pressures may restrict the eviction of real estate tenants in default. Highly leveraged real estate companies are particularly vulnerable to the effects of an economic downturn. Further, REITs are dependent upon management skills, may not be diversified and may have relatively small market capitalizations, which can increase volatility. REITs must satisfy certain requirements in order to qualify for favorable tax treatment under applicable tax laws, and a failure to qualify could adversely affect the value of the REIT. By investing in REITs through a fund, a shareholder will bear expenses of the REITs in addition to expenses of the fund and will not be entitled to the federal income tax deduction for qualified REIT dividends available to noncorporate investors that own REITs directly unless certain holding period and other requirements are satisfied.

Non-diversification risk. The fund is classified as non-diversified under the Investment Company Act of 1940, as amended. This means that the fund may invest in securities of relatively few issuers. Thus, the performance of one or a small number of portfolio holdings can affect overall performance.

Credit risk. The fund's performance could be hurt if an issuer of a debt security suffers an adverse change in financial condition that results in the issuer not making timely payments of interest or principal, a security downgrade or an inability to meet a financial obligation. Credit risk is greater for lower-rated securities.

Because the issuers of high-yield debt securities, or junk bonds (debt securities rated below the fourth highest credit rating category), may be in uncertain financial health, the prices of their debt securities can be more vulnerable to bad economic news, or even the expectation of bad news, than investment-grade debt securities. Credit risk for high-yield securities is greater than for higher-rated securities.

Interest rate risk. When interest rates rise, prices of debt securities generally decline. The longer the duration of the fund’s debt securities, the more sensitive the securities will be to interest rate changes. (As a general rule, a 1% rise in interest rates means a 1% fall in value for every year of duration.) Interest rates can change in response to the supply and demand for credit, government and/or central bank monetary policy and action, inflation rates, and other factors. Changing interest rates may have

unpredictable effects on markets, may result in heightened market volatility and potential illiquidity and may detract from fund performance to the extent the fund is exposed to such interest rates and/or volatility.

Security selection risk. The securities in the fund’s portfolio may decline in value. Portfolio management could be wrong in its analysis of industries, companies, economic trends, ESG factors, the relative attractiveness of different securities or other matters.

Securities lending risk. Securities lending involves the risk that the fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. A delay in the recovery of loaned securities could interfere with the fund’s ability to vote proxies or settle transactions. Delayed settlement may limit the ability of the fund to reinvest the proceeds of a sale of securities or prevent the fund from selling securities at times and prices it considers desirable. The fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities, or a decline in the value of any investments made with cash collateral or even a loss of rights in the collateral should the borrower of the securities fail financially while holding the securities.

Counterparty risk. A financial institution or other counterparty with whom the fund does business, or that underwrites, distributes or guarantees any investments or contracts that the fund owns or is otherwise exposed to, may decline in financial health and become unable to honor its commitments. This could cause losses for the fund or could delay the return or delivery of collateral or other assets to the fund.

Liquidity risk. In certain situations, it may be difficult or impossible to sell an investment and/or the fund may sell certain investments at a price or time that is not advantageous in order to meet redemption requests or other cash needs. Unusual market conditions, such as an unusually high volume of redemptions or other similar conditions could increase liquidity risk for the fund.

Pricing risk. If market conditions make it difficult to value some investments, the fund may value these investments using more subjective methods and the value determined for an investment may be materially different from the value realized upon such investment’s sale. As a result, you could pay more than the market value when buying fund shares or receive less than the market value when selling fund shares.

corrupted and operations may be disrupted (e.g., cyber-attacks, operational failures or broader disruptions may cause the release of private shareholder information or confidential fund information, interfere with the processing of shareholder transactions, impact the ability to calculate the fund’s net asset value and impede trading). Market events and disruptions also may trigger a volume of transactions that overloads current information technology and communication systems and processes, impacting the ability to conduct the fund’s operations.

While the fund and its service providers may establish business continuity and other plans and processes that seek to address the possibility of and fallout from cyber-attacks, disruptions or failures, there are inherent limitations in such plans and systems, including that they do not apply to third parties, such as fund counterparties, issuers of securities held by the fund or other market participants, as well as the possibility that certain risks have not been identified or that unknown threats may emerge in the future and there is no assurance that such plans and processes will be effective. Among other situations, disruptions (for example, pandemics or health crises) that cause prolonged periods of remote work or significant employee absences at the fund’s service providers could impact the ability to conduct the fund’s operations. In addition, the fund cannot directly control any cybersecurity plans and systems put in place by its service providers, fund counterparties, issuers of securities held by the fund or other market participants.

Active trading risk. Active securities trading could raise transaction costs and could result in increased taxable distributions to shareholders and distributions that would be taxable to shareholders at higher federal income tax rates.

Principal Investment Strategies

Main investments. Under normal circumstances, the fund invests at least 80% of net assets in the securities of US and non-US infrastructure-related companies. For purposes of the fund's 80% investment policy, the term “net assets” means the fund's net assets, plus the amount of any borrowings for investment purposes. The fund considers a company to be an infrastructure-related company if at least 50% of its non-cash assets are infrastructure assets or 50% of its gross income or net profits are derived, directly or indirectly, from the ownership, management, construction, operation, utilization or financing of infrastructure assets. Examples of infrastructure assets include transportation assets (such as toll roads, bridges, airports and seaports), utility assets (such as generating stations, gas and electric lines, water and sewer facilities, and communications networks) and social assets (such as hospitals, schools, and subsidized housing). The fund will invest 25% or more of its total

assets in securities of companies engaged principally in infrastructure-related companies. The fund may invest in companies of any market capitalization.

Under normal circumstances, the fund invests mainly in equity securities, though it may also invest in fixed-income securities without limitation. The fund allocates its assets among various regions and countries, including emerging market countries, and normally invests most of its assets in issuers that are organized or located outside the US or that do a substantial amount of business outside the US.

Due to regulatory changes, effective June 11, 2026, the fund will replace the 80% investment policy and related disclosures set forth in this prospectus. Specifically, effective June 11, 2026, under normal circumstances, the fund invests at least 80% of net assets, plus the amount of any borrowings for investment purposes, in the securities of US and non-US infrastructure-related companies.

Management process. In choosing securities, portfolio management uses a combination of two analytical disciplines:

Top-down research. Portfolio management analyzes various factors, including infrastructure market dynamics (such as supply/demand conditions), the economic environment (such as interest rates, inflation and economic growth), expected capital flow dynamics and exchange rate conditions.

Bottom-up research. Portfolio management analyzes characteristics and investment prospects of a particular security relative to others in its local market to actively manage the fund’s exposure to individual securities within each region. Disciplined valuation analysis drives this decision-making process, guiding portfolio management to invest in securities it believes can provide superior returns over the long-term, and to sell those that it believes no longer represent the strongest prospects. In addition to valuing the cash flow stream of the underlying assets, this analysis primarily considers a company's balance sheet, the quality and geography of the infrastructure asset, the management team, liquidity, and a number of environmental, social and governance (ESG) considerations, each of which can impact an investment's risks and expected returns. Lastly, portfolio management considers the global infrastructure markets in general when making investment decisions.

In addition, geopolitical and other globally interconnected occurrences, including war, terrorism, economic uncertainty or financial crises, contagion, tariffs and trade disputes, government debt crises (including defaults or downgrades) or uncertainty about government debt payments, government shutdowns, public health crises, natural disasters, supply chain disruptions, climate change and related events or conditions, have led, and in the future may lead, to disruptions in the US and world economies and markets, which may increase financial market volatility and have significant adverse direct or indirect effects on the fund and its investments. Adverse market conditions or disruptions could cause the fund to lose money, experience significant redemptions, and encounter operational difficulties. Although multiple asset classes may be affected by adverse market conditions or a particular market disruption, the duration and effects may not be the same for all types of assets.

Current military and other armed conflicts in various geographic regions, including those in Europe and the Middle East, can lead to, and have led to, economic and market disruptions, which may not be limited to the geographic region in which the conflict is occurring. Such conflicts can also result, and have resulted in some cases, in sanctions being levied by the United States, the European Union and/or other countries against countries or other actors involved in the conflict. In addition, such conflicts and related sanctions can adversely affect regional and global energy, commodities, financial and other markets and thus could affect the value of the fund's investments. The extent and duration of any military conflict, related sanctions and resulting economic and market disruptions are impossible to predict, but could be substantial.

DWS RREEF Global Infrastructure Fund

Infrastructure-related companies risk. The fund invests primarily in the securities of infrastructure-related companies, and will therefore be susceptible to adverse economic, business, regulatory or other occurrences affecting infrastructure-related companies. Infrastructure-related companies can be negatively affected by various factors, including general or local economic conditions and political developments, general changes in market sentiment towards infrastructure assets, high interest costs in connection with capital construction and improvement programs, difficulty in raising capital, costs associated with compliance with changes in regulations, regulation or intervention by various government authorities, including government regulation of rates, inexperience with and potential losses resulting from the deregulation of a particular industry or sector, changes in tax laws, tariffs and trade policies, environmental problems, costs or disruptions caused by extreme weather or other natural disasters, the effects of energy conservation policies, commodities markets disruptions (e.g., significant changes over short time periods in the price of oil), technological changes, surplus capacity, casualty losses, threat of terrorist attacks and changes in interest rates. Rising interest rates could lead to higher financing costs and reduced earnings for infrastructure-related companies. Infrastructure-related companies may be focused in the energy, industrials and utilities sectors. At times, the performance of securities in these sectors may lag the performance of other sectors or the broader market as a whole. A downturn in these sectors could have an adverse impact on the fund.

Foreign investment risk. The fund faces the risks inherent in foreign investing. Adverse political, economic or social developments, as well as US and foreign government actions such as the imposition of tariffs, economic and trade sanctions or embargoes, could undermine the value of the fund’s foreign investments, prevent the fund from realizing the full value of its foreign investments or prevent the fund from selling foreign securities it holds.

in non-US dollar denominated foreign securities, changes in currency exchange rates may affect the US dollar value of foreign securities or the income or gain received on these securities. In addition, because non-US markets may be open on days when the fund does not price its shares, the value of the foreign securities in the fund’s portfolio may change on days when shareholders will not be able to purchase or sell the fund’s shares.

Emerging markets risk. Foreign investment risks are greater in emerging markets than in developed markets. Investments in emerging markets are often considered speculative.

Currency risk. Changes in currency exchange rates may affect the value of the fund’s investments and the fund’s share price. The value of currencies are influenced by a variety of factors, that include: interest rates, national debt levels and trade deficits, changes in balances of payments and trade, domestic and foreign interest and inflation rates, global or regional political, economic or financial events, actual or potential government intervention, global energy prices, political instability and government monetary policies and the buying or selling of currency by a country’s government. Investments in foreign currencies are subject to the risk that those currencies will decline in value relative to the US dollar or, in the case of hedged positions, that the US dollar will decline relative to the currency being hedged. Currency exchange rates can be volatile and can change quickly and unpredictably, thereby impacting the value of the fund’s investments.

Medium-sized company risk. Medium-sized company stocks tend to be more volatile than large company stocks. Because stock analysts are less likely to follow medium-sized companies, less information about them is available to investors. Industry-wide reversals may have a greater impact on medium-sized companies, since they may lack the financial resources of larger companies. Medium-sized company stocks are typically less liquid than large company stocks.

impact on small companies, since they may lack the financial resources of larger companies. Small company stocks are typically less liquid than large company stocks.

Operational and technology risk. Cyber-attacks, disruptions or failures that affect the fund’s service providers or counterparties, issuers of securities held by the fund, or other market participants may adversely affect the fund and its shareholders, including by causing losses for the fund or impairing fund operations. For example, the fund’s or its service providers’ assets or sensitive or confidential information may be misappropriated, data may be corrupted and operations may be disrupted (e.g., cyber-attacks, operational failures or broader disruptions may cause the release of private shareholder information or confidential fund information, interfere with the processing of shareholder transactions, impact the ability to calculate the fund’s net asset value and impede trading). Market events and disruptions also may trigger a volume of transactions that overloads current information technology and communication systems and processes, impacting the ability to conduct the fund’s operations.

PORTFOLIO TURNOVER

Principal Investment Strategies

Main investments. Under normal circumstances, the fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity and debt securities issued by real estate companies, such as real estate investment trusts (REITs), REIT-like structures or real estate operating companies. A company will be considered a real estate company if, in the opinion of portfolio management, at least 50% of its revenues or at least 50% of the market value of its assets at the time the security is purchased are attributable to the ownership, construction, financing, management or sale of real estate or such other activities that are primarily related to real estate. The fund may invest without limitation in securities of companies engaged principally in the real estate industry.

The fund may also invest a portion of its assets in other types of securities. These securities may include short-term securities, bonds, notes, securities of companies not

principally engaged in the real estate industry and other similar securities. The fund allocates its assets among various regions and countries, including potentially emerging market countries, and normally invests a significant amount of its assets in non-US issuers.

Management process. In choosing securities, portfolio management uses a combination of two analytical disciplines:

Top-down research. Portfolio management analyzes market-wide investment conditions to arrive at the fund’s weighting across regional markets (i.e., the portfolio weighting across investments in the Americas, Europe, Asia and Australia), and, within these regions, its strategy across investment sectors, such as office, industrial, retail, hospitality and residential apartment real estate sectors.

Bottom-up research. Portfolio management analyzes characteristics and investment prospects of a particular security relative to others in its local market to actively manage the fund’s exposure to individual securities within each region. Disciplined valuation analysis drives this decision-making process, guiding portfolio management to invest in securities they believe can provide superior returns over the long-term, and to sell those that they believe no longer represent the strongest prospects. In its analysis, portfolio management primarily considers a company's balance sheet, the quality and geography of the property, the management team, liquidity, and a number of environmental, social and governance (ESG) considerations, each of which can impact an investment's risks and expected returns. Lastly, portfolio management considers the global real estate securities markets in general when making investment decisions.

groups of companies. The market as a whole may not favor the types of investments the fund makes, which could adversely affect a stock’s price, regardless of how well the company performs, or the fund’s ability to sell a stock at an attractive price. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. Events in the US and global financial markets, including actions taken by the US Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility which could negatively affect performance. High market volatility may also result from significant shifts in momentum of one or more specific stocks due to unusual increases or decreases in trading activity. Momentum can change quickly, and securities subject to shifts in momentum may be more volatile than the market as a whole and returns on such securities may drop precipitously. To the extent that the fund invests in a particular geographic region, capitalization or sector, the fund’s performance may be affected by the general performance of that region, capitalization or sector.

Real estate securities risk. The fund may invest without limitation in securities of companies engaged principally in the real estate industry, and will therefore be susceptible to adverse economic, business, legal, regulatory or other occurrences affecting real estate companies. Real estate companies, including REITs, can be negatively affected by the risks associated with direct ownership of real estate, such as general or local economic conditions, decreases in real estate value, increases in property taxes, operating expenses or insurance costs, lack of availability of insurance coverage, liabilities or losses due to environmental problems, extreme weather or natural disasters, delays in completion of construction, falling rents (whether due to poor demand, increased competition, overbuilding, or limitations on rents), zoning changes, rising interest rates, lack of credit, failure of borrowers to repay loans and losses from casualty or condemnation. In addition, real estate values have been subject to substantial fluctuations and declines on a local, regional and national basis in the past and may continue to be in the future. During periods of rising interest rates, real estate securities may lose appeal for investors who may be able to obtain higher yields from other income-producing investments. Rising interest rates may also mean that financing for property purchases and improvements is more costly and difficult to obtain. In addition, many real estate companies, including REITs, utilize leverage which increases investment risk. Political or regulatory pressures may restrict the eviction of real estate tenants in default. Highly leveraged real estate companies are particularly vulnerable to the effects of an economic downturn. Further, REITs are dependent upon management skills, may not be diversified and may have relatively small market capitalizations, which can increase volatility. REITs must satisfy certain requirements in order to qualify for favorable tax treatment under applicable tax laws, and a failure to qualify could adversely affect the value of the REIT. By investing in REITs through a fund, a shareholder will bear expenses of the REITs in addition to expenses of the fund and will not be entitled to the federal income tax deduction for qualified REIT dividends available to noncorporate investors that own REITs directly unless certain holding period and other requirements are satisfied.

In addition, because non-US markets may be open on days when the fund does not price its shares, the value of the foreign securities in the fund’s portfolio may change on days when shareholders will not be able to purchase or sell the fund’s shares.

Emerging markets risk. Foreign investment risks are greater in emerging markets than in developed markets. Investments in emerging markets are often considered speculative.

Small company risk. Small company stocks tend to be more volatile than medium-sized or large company stocks. Because stock analysts are less likely to follow small companies, less information about them is available to investors. Industry-wide reversals may have a greater impact on small companies, since they may lack the financial resources of larger companies.

Additional Information About Fund Strategies and Risks

DWS RREEF Real Estate Securities Fund

Investment Objective

The fund’s investment objective is long-term capital appreciation and current income.

Principal Investment Strategies

The fund’s equity investments are mainly common stocks, but may also include other types of equities, such as preferred or convertible stocks.

The fund may invest in different types of REITs. So-called equity REITs buy real estate and pay investors from the rents they receive and from any profits on the sale of their properties. So-called mortgage REITs lend money to real estate companies and pay investors from the interest they

receive on those loans. So-called hybrid REITs engage in both owning real estate and making loans. While portfolio management expects that the fund’s assets will be invested primarily in equity REITs, in changing market conditions, the fund may invest more significantly in other types of REITs.

Management process. In choosing securities, portfolio management uses a combination of two analytical disciplines:

Active trading. The fund may trade securities actively and this may lead to high portfolio turnover.

Prospectus May 1, 2025

Fund Details

Other Investment Strategies

Derivatives. The fund may invest in derivatives, which are financial instruments whose performance is derived, at least in part, from the performance of an underlying asset, security or index. The fund may use various types of derivatives (i) for hedging purposes; (ii) for risk management; (iii) for non-hedging purposes to seek to enhance potential gains; or (iv) as a substitute for direct investment in a particular asset class or to keep cash on hand to meet shareholder redemptions.

Main Risks

disruptions that have far-reaching effects on financial markets worldwide. The value of the fund’s investments may be negatively affected by adverse changes in overall economic or market conditions, such as the level of economic activity and productivity, unemployment and labor force participation rates, inflation or deflation (and expectations for inflation or deflation), interest rates, demand and supply for particular products or resources including labor, debt levels and credit ratings, and trade policies, among other factors. Such adverse conditions may contribute to an overall economic contraction across entire economies or markets, which may negatively impact the profitability of issuers operating in those economies or markets. In addition, geopolitical and other globally interconnected occurrences, including war, terrorism, economic uncertainty or financial crises, contagion, tariffs and trade disputes, government debt crises (including defaults or downgrades) or uncertainty about government debt payments, government shutdowns, public health crises, natural disasters, supply chain disruptions, climate change and related events or conditions, have led, and in the future may lead, to disruptions in the US and world economies and markets, which may increase financial market volatility and have significant adverse direct or indirect effects on the fund and its investments. Adverse market conditions or disruptions could cause the fund to lose money, experience significant redemptions, and encounter operational difficulties. Although multiple asset classes may be affected by adverse market conditions or a particular market disruption, the duration and effects may not be the same for all types of assets.

volatility. REITs must satisfy certain requirements in order to qualify for favorable tax treatment under applicable tax laws, and a failure to qualify could adversely affect the value of the REIT. By investing in REITs through a fund, a shareholder will bear expenses of the REITs in addition to expenses of the fund and will not be entitled to the federal income tax deduction for qualified REIT dividends available to noncorporate investors that own REITs directly unless certain holding period and other requirements are satisfied.

sale of securities or prevent the fund from selling securities at times and prices it considers desirable. The fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities, or a decline in the value of any investments made with cash collateral or even a loss of rights in the collateral should the borrower of the securities fail financially while holding the securities.

This risk can be ongoing for any security that does not trade actively or in large volumes, for any security that trades primarily on smaller markets, and for investments that typically trade only among a limited number of large investors (such as certain types of derivatives or restricted securities). In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). This may affect only certain securities or an overall securities market.

Secondary markets may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods, which may prevent the fund from being able to realize full value and thus sell a security for its full valuation. This could cause a material decline in the fund’s net asset value.

to sell the derivative because of an illiquid secondary market; the risk that a counterparty is unwilling or unable to meet its obligation, which risk may be heightened in derivative transactions entered into “over-the-counter” (i.e., not on an exchange or contract market); and the risk that the derivative transaction could expose the fund to the effects of leverage, which could increase the fund's exposure to the market and magnify potential losses.

There is no guarantee that derivatives, to the extent employed, will have the intended effect, and their use could cause lower returns or even losses to the fund. The use of derivatives by the fund to hedge risk may reduce the opportunity for gain by offsetting the positive effect of favorable price movements.

them. In addition, power or communications outages, acts of god, information technology equipment malfunctions, operational errors, and inaccuracies within software or data processing systems may also disrupt business operations or impact critical data.

Cyber-attacks, disruptions, or failures may adversely affect the fund and its shareholders or cause reputational damage and subject the fund to regulatory fines, litigation costs, penalties or financial losses, reimbursement or other compensation costs, and/or additional compliance costs. In addition, cyber-attacks, disruptions, or failures involving a fund counterparty could affect such counterparty’s ability to meet its obligations to the fund, which may result in losses to the fund and its shareholders. Similar types of operational and technology risks are also present for issuers of securities held by the fund, which could have material adverse consequences for such issuers, and may cause the fund’s investments to lose value. Furthermore, as a result of cyber-attacks, disruptions, or failures, an exchange or market may close or issue trading halts on specific securities or the entire market, which may result in the fund being, among other things, unable to buy or sell certain securities or financial instruments or unable to accurately price its investments.

For example, the fund relies on various sources to calculate its NAV. Therefore, the fund is subject to certain operational risks associated with reliance on third party service providers and data sources. NAV calculation may be impacted by operational risks arising from factors such as failures in systems and technology. Such failures may result in delays in the calculation of the fund’s NAV and/or the inability to calculate NAV over extended time periods. The fund may be unable to recover any losses associated with such failures.

DWS RREEF Global Infrastructure Fund

Investment Objective

The fund seeks total return from both capital appreciation and current income.

Principal Investment Strategies

company if at least 50% of its non-cash assets are infrastructure assets or 50% of its gross income or net profits are derived, directly or indirectly, from the ownership, management, construction, operation, utilization or financing of infrastructure assets. Examples of infrastructure assets include transportation assets (such as toll roads, bridges, airports and seaports), utility assets (such as generating stations, gas and electric lines, water and sewer facilities, and communications networks) and social assets (such as hospitals, schools, and subsidized housing). The fund will invest 25% or more of its total assets in securities of companies engaged principally in infrastructure-related companies. The fund may invest in companies of any market capitalization.

Due to regulatory changes, effective June 11, 2026, the fund will replace the 80% investment policy and related disclosures set forth in this prospectus. Specifically, effective June 11, 2026, under normal circumstances, the fund invests at least 80% of net assets, plus the amount of any borrowings for investment purposes, in the securities of US and non-US infrastructure-related companies.

Infrastructure assets are physical assets, structures and networks that provide necessary services and operations to society. The fund focuses on companies with a direct investment in infrastructure assets and to a lesser degree on companies that operate or use infrastructure assets in their business (such as electric utilities and airlines) or companies with indirect exposure to infrastructure investment (such as suppliers of construction materials).

The fund may invest in common and preferred stock (including convertible securities), rights or warrants to purchase common stock, debt securities and listed limited partnership interests.

The fund may invest in unlisted securities, provided that the portfolio managers expect such securities to be listed on a recognized public stock exchange or traded over the counter within six months from the time of investment.

Management process. In choosing securities, portfolio management uses a combination of two analytical disciplines:

Prospectus May 1, 2025

Fund Details

Portfolio management begins by taking into consideration the insights of both an in-house private infrastructure advisory group and a research team. These resources provide different perspectives on political, regulatory, demographic and other qualitative characteristics in many of the countries and regions in which the fund invests.

The fund’s security selection strategy focuses on identifying securities with the potential for attractive total return, typically through a combination of price appreciation and dividend income. It is expected that the majority of returns from the fund will be generated by security-specific investment decisions.

defaults or downgrades) or uncertainty about government debt payments, government shutdowns, public health crises, natural disasters, supply chain disruptions, climate change and related events or conditions, have led, and in the future may lead, to disruptions in the US and world economies and markets, which may increase financial market volatility and have significant adverse direct or indirect effects on the fund and its investments. Adverse market conditions or disruptions could cause the fund to lose money, experience significant redemptions, and encounter operational difficulties. Although multiple asset classes may be affected by adverse market conditions or a particular market disruption, the duration and effects may not be the same for all types of assets.

Financial reporting standards for companies based in foreign markets differ from those in the US. Additionally, foreign securities markets generally are smaller and less liquid than US markets. To the extent that the fund invests in non-US dollar denominated foreign securities, changes in currency exchange rates may affect the US dollar value of foreign securities or the income or gain received on these securities. In addition, because non-US markets may be open on days when the fund does not price its shares,

Prospectus May 1, 2025

Fund Details

the value of the foreign securities in the fund’s portfolio may change on days when shareholders will not be able to purchase or sell the fund’s shares.

Foreign governments may restrict investment by foreigners, limit withdrawal of trading profit or currency from the country, restrict currency exchange or seize foreign investments. The foreign investments of the fund may also be subject to foreign withholding or other taxes. Foreign brokerage commissions and other fees are generally higher than those for US investments, and the transactions and custody of foreign assets may involve delays in payment, delivery or recovery of money or investments.

Foreign markets can have liquidity risks beyond those typical of US markets. Because foreign exchanges generally are smaller and less liquid than US exchanges, buying and selling foreign investments can be more difficult and costly. Relatively small transactions can sometimes materially affect the price and availability of foreign securities. In certain situations, it may become virtually impossible to sell a foreign investment in an orderly fashion at a price that approaches portfolio management's estimate of its value. For the same reason, it may at times be difficult to value the fund’s foreign investments.

Emerging markets risk. Foreign investment risks are greater in emerging markets than in developed markets. Investments in emerging markets are often considered speculative.

Emerging markets countries typically have economic and political systems that are less developed, and can be expected to be less stable than developed markets. For example, the economies of such countries can be subject to rapid and unpredictable rates of inflation or deflation.

Applicable regulatory, accounting, auditing and financial reporting and recordkeeping standards may be less rigorous in emerging markets countries and there may be significant differences between financial statements prepared in accordance with emerging markets countries’ accounting standards and practices and those prepared in accordance with international accounting standards. In particular, the assets and profits appearing on the financial statements of an emerging market country’s issuer may not reflect its financial position or results of operations in the way they would be reflected had such financial statements been prepared in accordance with US Generally Accepted Accounting Principles. The quality of audits in emerging markets countries may be unreliable. Consequently, the fund may not be provided the same degree of protection or information as would generally apply in developed countries and the fund may be exposed to significant losses.

and/or central bank monetary policy and action, inflation rates, and other factors. Changing interest rates may have unpredictable effects on markets, may result in heightened market volatility and potential illiquidity and may detract from fund performance to the extent the fund is exposed to such interest rates and/or volatility.

Derivatives risk. Derivatives involve risks different from, and possibly greater than, the risks associated with investing directly in securities and other more traditional investments. Risks associated with derivatives may include the risk that the derivative is not well correlated with the underlying asset, security or index to which it relates; the risk that derivatives may result in losses or missed opportunities; the risk that the fund will be unable to sell the derivative because of an illiquid secondary market; the risk that a counterparty is unwilling or unable to meet its obligation, which risk may be heightened in derivative transactions entered into “over-the-counter” (i.e., not on an exchange or contract market); and the risk that the derivative transaction could expose the fund to the effects of leverage, which could increase the fund's exposure to the market and magnify potential losses.

of shareholder transactions, impact the ability to calculate the fund’s net asset value and impede trading). Market events and disruptions also may trigger a volume of transactions that overloads current information technology and communication systems and processes, impacting the ability to conduct the fund’s operations.

Cyber-attacks may include unauthorized attempts by third parties to improperly access, modify, disrupt the operations of, or prevent access to the systems of the fund’s service providers or counterparties, issuers of securities held by the fund or other market participants or data within them. In addition, power or communications outages, acts of god, information technology equipment malfunctions, operational errors, and inaccuracies within software or data processing systems may also disrupt business operations or impact critical data.

DWS RREEF Global Real Estate Securities Fund

Investment Objective

The fund’s investment objective is to seek total return through a combination of current income and long-term capital appreciation.

Principal Investment Strategies

The fund may also invest a portion of its assets in other types of securities. These securities may include short-term securities, bonds, notes, securities of companies not principally engaged in the real estate industry and other similar securities. The fund allocates its assets among various regions and countries, including potentially emerging market countries, and normally invests a significant amount of its assets in non-US issuers.

The fund’s equity investments are mainly common stocks, but may also include other types of equities, such as preferred or convertible stocks. Currently, the fund does not intend to borrow for investment purposes.

Management process. In choosing securities, portfolio management uses a combination of two analytical disciplines:

Asia and Australia), and, within these regions, its strategy across investment sectors, such as office, industrial, retail, hospitality and residential apartment real estate sectors.

Bottom-up research. Portfolio management analyzes characteristics and investment prospects of a particular security relative to others in its local market to actively manage the fund’s exposure to individual securities within each region. Disciplined valuation analysis drives this decision-making process, guiding portfolio management to invest in securities they believe can provide superior returns over the long-term, and to sell those that they believe no longer represent the strongest prospects. In its analysis, portfolio management primarily considers a company's balance sheet, the quality and geography of the property, the management team, liquidity, and a number of environmental, social and governance (ESG) considerations, each of which can impact an investment's risks and expected returns. Lastly, portfolio management considers the global real estate securities markets in general when making investment decisions.

The fund seeks to take advantage of the extensive expertise of its investment advisor’s and its affiliates’ dedicated, in-house direct real estate investment teams located in the United States, Europe and Australia.

Portfolio management’s top-down research includes analysis of various factors, including real estate market dynamics (such as supply/demand conditions), the economic environment (such as interest rates, inflation and economic growth), expected capital flow dynamics and exchange rate conditions.

The fund’s security selection strategy focuses on identifying securities that have the potential for price appreciation and pay attractive, reliable dividends. It is expected that the majority of the fund’s returns will be generated by security-specific investment decisions, which are the responsibility of portfolio managers located in the respective geographical regions.

The Global Property Asset Allocation Committee of the investment advisor and its affiliates, which is comprised of the portfolio managers from each region and chaired by the lead portfolio manager for global real estate security investments, determines the allocation of the fund’s investments across geographic regions.

which may result in losses to the fund and its shareholders. Similar types of operational and technology risks are also present for issuers of securities held by the fund, which could have material adverse consequences for such issuers, and may cause the fund’s investments to lose value. Furthermore, as a result of cyber-attacks, disruptions, or failures, an exchange or market may close or issue trading halts on specific securities or the entire market, which may result in the fund being, among other things, unable to buy or sell certain securities or financial instruments or unable to accurately price its investments.

Other Policies and Risks

While the previous pages describe the main points of each fund’s strategy and risks, there are a few other matters to know about:

■

Although major changes tend to be infrequent, each fund’s Board could change a fund's investment objective without seeking shareholder approval. However, the Board will provide shareholders with at least 60 days' notice prior to making any changes to the 80% investment policy of DWS RREEF Real Estate Securities Fund and DWS RREEF Global Infrastructure Fund, as described herein. For DWS RREEF Global Real Estate Securities Fund, the fund’s 80% investment policy may be changed only by the affirmative vote of at least (i) 80% of the continuing trustees of the fund (as defined in the fund’s Bylaws) and (ii) 80% of the votes entitled to be cast by the shareholders of the fund. Any major changes to a fund could result in significant portfolio turnover and/or significant redemptions from the fund which could raise transaction costs and could result in increased taxable distributions to shareholders and distributions that would be taxable to shareholders at higher federal income tax rates.

■

When, in the Advisor's opinion, it is advisable to adopt a temporary defensive position because of unusual and adverse or other market conditions, up to 100% of each fund's assets may be held in cash or invested in money market securities or other short-term investments. Short-term investments consist of (1) foreign and domestic obligations of sovereign governments and their agencies and instrumentalities, authorities and political subdivisions; (2) other short-term high quality (for DWS RREEF Real Estate Securities Fund and DWS RREEF Global Infrastructure Fund) or investment-grade (for

Prospectus May 1, 2025

Fund Details

DWS RREEF Global Real Estate Securities Fund) rated debt securities or, if unrated, determined to be of comparable quality in the opinion of the Advisor; (3) commercial paper; (4) bank obligations, including negotiable certificates of deposit, time deposits and bankers' acceptances; and (5) repurchase agreements. Short-term investments may also include shares of money market mutual funds. To the extent a fund invests in such instruments, the fund will not be pursuing its investment objective. However, portfolio management may choose to not use these strategies for various reasons, even in volatile market conditions.

■

Each fund may trade actively. This could raise transaction costs and could result in increased taxable distributions to shareholders and distributions that would be taxable to shareholders at higher federal income tax rates.

■

From time to time, a fund may have a concentration of shareholder accounts holding a significant percentage of shares outstanding. Investment activities of these shareholders could have a material impact on a fund.

■

Your fund assets may be at risk of being transferred to the appropriate state if you fail to maintain a valid address and/or if certain activity does not occur in your account within the time specified by state abandoned property law. Contact your financial representative or the transfer agent for additional information.

■

Shareholders of a fund (which may include affiliated and/or non-affiliated registered investment companies that invest in a fund) may make relatively large redemptions or purchases of fund shares. These transactions may cause a fund to have to sell securities or invest additional cash, as the case may be. While it is impossible to predict the overall impact of these transactions over time, there could be adverse effects on a fund’s performance to the extent that a fund may be required to sell securities or invest cash at times when it would not otherwise do so. These transactions could adversely impact a fund’s liquidity, accelerate the recognition of taxable income if sales of securities resulted in capital gains or other income and increase transaction costs, which may adversely affect a fund’s performance. These transactions could also adversely impact a fund’s ability to implement its investment strategies and pursue its investment objective, and, as a result, a larger portion of a fund’s assets may be held in cash or cash equivalents. In addition, large redemptions could significantly reduce a fund’s assets, which may result in an increase in a fund’s expense ratio on account of expenses being spread over a smaller asset base and/or the loss of fee breakpoints.

This prospectus doesn’t tell you about every policy or risk of investing in each fund. If you want more information on each fund’s allowable securities and investment practices and the characteristics and risks of each one, you may want to request a copy of the Statement of Additional Information (the back cover tells you how to do this).

Keep in mind that there is no assurance that a fund will achieve its investment objective.

Fund Details

The Advisor may utilize the resources of its global investment platform to provide investment management services through branch offices or affiliates located outside the US. In some cases, the Advisor may also utilize its branch offices or affiliates located in the US or outside the US to perform certain services, such as trade execution, trade matching and settlement, or various administrative, back-office or other services. To the extent services are performed outside the US, such activity may be subject to both US and foreign regulation. It is possible that the jurisdiction in which the Advisor or its affiliate performs such services may impose restrictions or limitations on portfolio transactions that are different from, and in addition to, those that apply in the US.

Management Fee. The Advisor receives a management fee from each fund. Below are the actual rates paid by each fund for the most recent fiscal year, as a percentage of each fund’s average daily net assets.

The agreement may only be terminated with the consent of the fund’s Board.

A discussion regarding the basis for the Board's approval of each fund’s investment management agreement and, as applicable, subadvisory agreement, and sub-subadvisory agreements is contained in the most recent financial statements and other information report for the annual period ended December 31 and the semi-annual period ended June 30 (see the back cover).

Under a separate administrative services agreement between each fund and the Advisor, each fund pays the Advisor a fee of 0.097% of the fund’s average daily net assets for providing most of each fund's administrative services. The administrative services fee discussed above is included in the fees and expenses table under “Other expenses.”

Multi-Manager Structure. The Advisor, subject to the approval of the Board, has ultimate responsibility to oversee any subadvisor to a fund and to recommend the hiring, termination and replacement of subadvisors. Each fund and the Advisor have received an order from the SEC that permits the Advisor to appoint or replace certain subadvisors, to manage all or a portion of a fund’s assets and enter into, amend or terminate a subadvisory agreement with certain subadvisors, in each case subject to the approval of a fund’s Board but without obtaining shareholder approval (“multi-manager structure”). The multi-manager structure applies to subadvisors that are not affiliated with the fund or the Advisor (“nonaffiliated subadvisors”), as well as subadvisors that are indirect or direct, wholly-owned subsidiaries of the Advisor or that are indirect or direct, wholly-owned subsidiaries of the same company that, indirectly or directly, wholly owns the Advisor (“wholly-owned subadvisors”). Pursuant to the SEC order, the Advisor, with the approval of a fund’s Board, has the discretion to terminate any subadvisor and allocate and reallocate a fund’s assets among any other nonaffiliated subadvisors or wholly-owned subadvisors (including terminating a nonaffiliated subadvisor and replacing it with a wholly-owned subadvisor). Each fund and the Advisor are subject to the conditions imposed by the SEC order, including the condition that within 90 days of hiring a new subadvisor pursuant to the multi-manager structure, each fund will provide shareholders with an information statement containing information about the new subadvisor. The shareholders of DWS Real Estate Securities Fund and DWS Global Infrastructure Fund have approved the multi-manager structure described herein. DWS Global Real Estate Securities Fund cannot rely on the SEC order until shareholders have approved the multi-manager structure described herein.

This prospectus offers the share classes noted on the front cover. All classes of a fund have the same investment objective and investments, but each class has its own fees and expenses, offering you a choice of cost structures:

■

Class A shares and Class C shares are intended for investors seeking the advice and assistance of a financial representative, who will typically receive compensation for those services.

■

Class R shares, Class R6 shares and Institutional Class shares are only available to particular investors or through certain programs, as described below.

■

Class S shares are available through certain intermediary relationships with financial services firms, or can be purchased by establishing an account directly with the fund’s transfer agent.

Your financial representative may also charge you additional fees, commissions or other charges.

The following pages tell you how to invest in a fund and what to expect as a shareholder. The following pages also tell you about many of the services, choices and benefits of being a shareholder. You’ll also find information on how to check the status of your account.

If you’re investing directly with each fund’s transfer agent, all of this information applies to you. If you’re investing through a “third party provider” — for example, a workplace retirement plan, financial supermarket or financial representative — your provider may have its own policies or instructions and you should follow those. Refer to Appendix B “Sales Charge Waivers and Discounts Available Through Intermediaries” for information about available sales charge waivers and discounts through certain intermediaries.

You can find out more about the topics covered here by speaking with your financial representative or a representative of your workplace retirement plan or other investment provider. For an analysis of the fees associated with an investment in a fund or similar funds, please refer to tools.finra.org/fund_analyzer/ (this Web site does not form a part of this prospectus).

Each fund, the Distributor and the transfer agent do not provide investment advice or recommendations to existing or potential shareholders with respect to investing in a fund, including which class may be appropriate for you.

Choosing a Share Class

Before you invest, take a moment to look over the characteristics of each share class, so that you can be sure to choose the class that’s right for you.

We describe each share class in detail on the following pages. But first, you may want to look at the following table, which gives you a brief description and comparison of the main features of each class. You should consult with your financial representative to determine which class of shares is appropriate for you.

Classes and features	Points to help you compare
Class A
■Sales charge of up to 5.75% charged when you buy shares ■In most cases, no charge when you sell shares ■Up to 0.25% annual share- holder servicing fee	■Some investors may be able to reduce or eliminate their sales charge; see “Class A Shares” and Appendix B ■Total annual expenses are lower than those for Class C ■Distributions are generally higher than Class C
Class C

Class R6
■No sales charge when you buy shares and no deferred sales charge when you sell shares	■Only available to participants in certain qualifying plans and programs
Institutional Class
■No sales charge when you buy shares and no deferred sales charge when you sell shares	■Only available to certain institu- tional investors; typically $1,000,000 minimum initial investment ■Distributions are generally higher than Class A, Class C and Class R, and may be higher than Class S, depending on relative expenses
Class S
■No sales charge when you buy shares and no deferred sales charge when you sell shares	■Total annual expenses are lower than those for Class A, Class C and Class R ■Distributions are generally higher than Class A, Class C and Class R, and may be higher than Institutional Class, depending on relative expenses

The sales charge on purchases of Class A shares and the contingent deferred sales charge (CDSC) on redemptions of Class A and Class C shares are paid to the fund’s distributor, DDI, who may distribute all or a portion of the sales charge to your financial representative. In certain instances described below, a sales charge may be waived by DDI or your financial representative. If your financial representative agrees to waive any sales charge due to it from DDI, DDI will not collect the sales charge on your investment or redemption.

The availability of certain sales charge waivers and discounts may depend on whether you purchase your shares directly from each fund or through a financial intermediary. Intermediaries may have different policies and procedures regarding the availability of front-end sales charge waivers or CDSC waivers (see Appendix B). For waivers and discounts not available through a particular intermediary, you will have to purchase fund shares directly from each fund or through another intermediary. In all instances, it is your responsibility to notify a fund or your financial intermediary at the time of purchase of any relationship or other facts qualifying you for sales charge waivers or discounts.

Class A Shares

Class A shares may make sense for long-term investors, especially those who are eligible for a reduced or eliminated sales charge.

Class A shares have a 12b-1 plan, under which a shareholder servicing fee of up to 0.25% is deducted from class assets each year. Because the shareholder servicing fee is continuous in nature, it may, over time, increase the cost of your investment and may cost you more than paying other types of sales charges.

Class A shares have an up-front sales charge that varies with the amount you invest:

Your investment	Front-end sales charge as % of offering price1,2	Front-end sales charge as % of your net investment2
Under $50,000	5.75 %	6.10 %
$50,000–$99,999	4.50	4.71
$100,000–$249,999	3.50	3.63
$250,000–$499,999	2.60	2.67
$500,000–$999,999	2.00	2.04
$1 million or more	see below3	see below3

The “offering price”, the price you pay to buy shares, includes the sales charge which will be deducted directly from your investment.

Because of rounding in the calculation of the offering price, the actual front-end sales charge paid by an investor may be higher or lower than the percentages noted.

Refer to “Class A NAV Sales” below for additional details.

You may be able to lower your Class A sales charge if:

■

you indicate your intent in writing to invest at least $50,000 in any share class of any retail DWS fund (excluding direct purchase of DWS money market funds) over the next 24 months (Letter of Intent);

■

your holdings in all share classes of any retail DWS fund (excluding shares in DWS money market funds for which a sales charge has not previously been paid and computed at the maximum offering price at the time of the purchase for which the discount is applicable for Class A shares) you already own plus the amount you’re investing now in Class A shares is at least $50,000 (Cumulative Discount); or

■

you are investing a total of $50,000 or more in any share class of two or more retail DWS funds (excluding direct purchases of DWS money market funds) on the same day (Combined Purchases).

The point of these three features is to let you count investments made at other times or in certain other funds for purposes of calculating your present sales charge. Any time you can use the privileges to “move” your investment into a lower sales charge category, it’s generally beneficial for you to do so.

For purposes of determining whether you are eligible for a reduced Class A sales charge, you and your immediate family (i.e., your spouse or life partner and your children or stepchildren age 21 or younger) may aggregate your investments in the DWS funds. This includes, for example, investments held in a retirement account, an employee benefit plan or with a financial representative other than the one handling your current purchase. These combined investments will be valued at their current offering price to determine whether your current investment qualifies for a reduced sales charge.

To receive a reduction in your Class A initial sales charge, you must let your financial representative or Shareholder Services know at the time you purchase shares that you qualify for such a reduction. You may be asked by your

Prospectus May 1, 2025

Investing in the Funds

financial representative or Shareholder Services to provide account statements or other information regarding related accounts of you or your immediate family in order to verify your eligibility for a reduced sales charge.

Information about sales charge discounts is available free of charge. Please visit dws.com, refer to the section entitled “Purchase and Redemption of Shares” in each fund’s Statement of Additional Information or consult with your financial representative. Certain intermediaries may provide different sales charge discounts which are described under “Sales Charge Waivers and Discounts Available Through Intermediaries” in Appendix B to this prospectus.

In certain circumstances listed below, you may be able to buy Class A shares without a sales charge.In addition, certain intermediaries may provide different sales charge waivers. These waivers and the applicable intermediaries are described under “Sales Charge Waivers and Discounts Available Through Intermediaries” in Appendix B to this prospectus.Your financial representative or Shareholder Services can answer questions and help you determine if you are eligible for any of the sales charge waivers.

Class A NAV Sales. Class A shares may be sold at net asset value without a sales charge to:

(1)

investors investing $1 million or more, either as a lump sum or through the sales charge reduction features referred to above (collectively, the Large Order NAV Purchase Privilege). The Large Order NAV Purchase Privilege is not available if another net asset value purchase privilege is available. Purchases pursuant to the Large Order NAV Purchase Privilege may be subject to a CDSC of 1.00% if redeemed within 12 months of the original purchase date and 0.50% if redeemed within the following six months. The CDSC is waived under certain circumstances (see below);

selected employees (including their spouses or life partners and children or stepchildren age 21 or younger) of banks and other financial services firms that provide administrative services related to order placement and payment to facilitate transactions in shares of a DWS fund for their clients pursuant to an agreement with DDI or one of its affiliates. Only those employees of such banks and other firms who as part of their usual duties provide services related to transactions in fund shares qualify;

(8)

(9)

Such shares are sold for investment purposes and on the condition that they will not be resold except through redemption or repurchase by a fund;

(10)

financial service firms that have entered into an agreement with DDI to offer Class A shares through a no-load network, platform or self-directed brokerage account that may or may not charge transaction fees to their clients. Refer to the section entitled “Sales Charge Waivers and Discounts Available Through Intermediaries” in Appendix B to this prospectus for information about available sales charge waivers through certain intermediaries;

(11)

Employer-sponsored retirement plans that are maintained by a fund at an omnibus level or are part of retirement plans or platforms offered by banks, broker-dealers, financial representatives or insurance companies or serviced by retirement recordkeepers (each, an “Employer-Sponsored Retirement Plan”).

Prospectus May 1, 2025

Investing in the Funds

401(k) plans, 457 plans, employer-sponsored 403(b) plans, profit sharing and money purchase pension plans, defined benefit plans, and non-qualified deferred compensation plans, but does not include SEP IRAs, SIMPLE IRAs, or Salary Reduction Simplified Employee Pension Plans (SARSEPs) (each, an “Employer-Sponsored IRA”);

In addition, Class A shares may be sold at net asset value without a sales charge in connection with:

(13)

the acquisition of assets or merger or consolidation with another investment company, and under other circumstances deemed appropriate by DDI and consistent with regulatory requirements;

(14)

a direct “roll over” of a distribution from a DWS/Ascensus 403(b) Plan or from participants in employer sponsored employee benefit plans maintained on the OmniPlus subaccount recordkeeping system made available through ADP, Inc. under an alliance between ADP, Inc. and DDI and its affiliates into a DWS IRA;

Class A shares also may be purchased at net asset value without a sales charge in any amount by members of the plaintiff class in the proceeding known as Howard and Audrey Tabankin, et al. v. Kemper Short-Term Global Income Fund, et al., Case No. 93 C 5231 (N.D. IL). This privilege is generally non-transferable and continues for the lifetime of individual class members and has expired for non-individual class members. To make a purchase at net asset value under this privilege, the investor must, at the time of purchase, submit a written request that the purchase be processed at net asset value pursuant to this privilege specifically identifying the purchaser as a member of the “Tabankin Class.” Shares purchased under this privilege will be maintained in a separate account that includes only shares purchased under this privilege. For more details concerning this privilege, class members should refer to the Notice of (i) Proposed Settlement with Defendants; and (ii) Hearing to Determine Fairness of Proposed Settlement, dated August 31, 1995, issued in connection with the aforementioned court proceeding. For sales of fund shares at net asset value pursuant to this privilege, DDI may in its discretion pay dealers and other financial services firms a concession, payable quarterly, at an annual rate of up to 0.25% of net assets attributable to such shares maintained and serviced by the firm. A firm becomes eligible for the concession based upon assets

in accounts attributable to shares purchased under this privilege in the month after the month of purchase and the concession continues until terminated by DDI. The privilege of purchasing Class A shares of a fund at net asset value under this privilege is not available if another net asset value purchase privilege also applies.

The Class A CDSC for shares purchased through the Large Order NAV Purchase Privilege will be waived in the event of:

(1)

redemptions by a participant-directed qualified retirement plan described in Internal Revenue Code of 1986, as amended (Internal Revenue Code) Section 401(a), a participant-directed non-qualified deferred compensation plan described in Internal Revenue Code Section 457 or a participant-directed qualified retirement plan described in Internal Revenue Code Section 403(b)(7) which is not sponsored by a K-12 school district;

(2)

redemptions by (i) employer-sponsored employee benefit plans using the subaccount recordkeeping system made available through ADP, Inc. under an alliance between ADP, Inc. and DDI and its affiliates; or (ii) DWS/Ascensus 403(b) Plans;

(3)

redemption of shares of a shareholder (including a registered joint owner) who has died;

(4)

redemption of shares of a shareholder (including a registered joint owner) who after purchase of the shares being redeemed becomes totally disabled (as evidenced by a determination by the federal Social Security Administration);

(5)

redemptions under a fund’s Systematic Withdrawal Plan at a maximum of 12% per year of the net asset value of the account; and

(6)

redemptions for certain loan advances, hardship provisions or returns of excess contributions from retirement plans.

In addition, certain intermediaries may provide different CDSC waivers. These waivers and the applicable intermediaries are described under “Sales Charge Waivers and Discounts Available Through Intermediaries” in Appendix B to this prospectus.

Class C Shares

Class C shares may appeal to investors who aren’t certain of their investment time horizon.

With Class C shares, you pay no up-front sales charge to a fund. Class C shares have a 12b-1 plan, under which a distribution fee of 0.75% and a shareholder servicing fee of up to 0.25% are deducted from class assets each year. Because of the distribution fee, the annual expenses for Class C shares are higher than those for Class A shares (and the performance of Class C shares is correspondingly lower than that of Class A shares).

Prospectus May 1, 2025

Investing in the Funds

Class C shares have a CDSC, but only on shares you sell within one year of buying them:

Year after you bought shares	CDSC on shares you sell
First year	1.00 %
Second year and later	None

This CDSC is waived under certain circumstances described below.

(1)

(2)

redemption of shares of a shareholder (including a registered joint owner) who has died;

(3)

(4)

redemptions under a fund’s Systematic Withdrawal Plan at a maximum of 12% per year of the net asset value of the account;

(5)

redemption of shares by an employer-sponsored employee benefit plan that offers funds in addition to DWS funds and whose dealer of record has waived the advance of the first year administrative service and distribution fees applicable to such shares and agrees to receive such fees quarterly;

(6)

redemption of shares purchased through a dealer-sponsored asset allocation program maintained on an omnibus recordkeeping system provided the dealer of record had waived the advance of the first year administrative services and distribution fees applicable to such shares and has agreed to receive such fees quarterly;

(7)

redemptions made pursuant to any IRA systematic withdrawal based on the shareholder’s life expectancy including, but not limited to, substantially equal periodic payments described in Internal Revenue Code Section 72(t)(2)(A)(iv) prior to age 59 1/2; and

(8)

redemptions to satisfy required minimum distributions from an IRA account (with the maximum amount subject to this waiver being based only upon the shareholder’s DWS IRA accounts).

Your financial representative or Shareholder Services can answer your questions and help you determine if you’re eligible for a CDSC waiver. In addition, certain intermediaries may provide different CDSC waivers. These waivers and the applicable intermediaries are described under “Sales Charge Waivers and Discounts Available Through Intermediaries” in Appendix B to this prospectus.

While Class C shares do not have an up-front sales charge, their higher annual expenses because of the ongoing 12b-1 fees paid out of fund assets mean that, over the years, you could end up paying more than the equivalent of the maximum allowable up-front sales charge.

Orders to purchase Class C shares in excess of $500,000 will be declined with the exception of orders received from financial representatives acting for clients whose shares are held in an omnibus account and certain employer-sponsored employee benefit plans.

Class C shares automatically convert to Class A shares in the same fund after 8 years, provided that the fund or the financial intermediary through which the shareholder purchased the Class C shares has records verifying that the Class C shares have been held for at least 8 years. Due to operational limitations at your financial intermediary, your ability to have your Class C shares automatically converted to Class A shares may be limited. (For example, automatic conversion of Class C shares to Class A shares will not apply to fund shares held through group retirement plan recordkeeping platforms of certain broker-dealer intermediaries who hold such shares in an omnibus account and do not track participant level share lot aging. Such Class C shares would not satisfy the conditions for the automatic conversion.) Please consult your financial representative for more information. The automatic conversion of Class C shares to Class A shares would occur on the basis of the relative net asset values of the two classes without the imposition of any sales charges or other charges. Shareholders generally will not recognize a gain or loss for federal income tax purposes upon the conversion of Class C shares to Class A shares in the same fund.

Class R Shares

Class R shares have no initial sales charge or deferred sales charge. Class R shares have a 12b-1 plan, under which a distribution fee of 0.25% and a shareholder servicing fee of up to 0.25% are deducted from class assets each year. Because distribution fees are continuous in nature, these fees may, over time, increase the cost of your investment and may cost you more than paying other types of sales charges.

Eligibility Requirements. You may buy Class R shares if you are a participant in certain retirement plan platforms that offer Class R shares of the fund through a plan level or omnibus account, including:

■

Section 401(a) and 457 plans

■

Certain section 403(b)(7) plans

In addition, each fund, in its discretion, may waive the minimum initial investment for a specific employee benefit plan (or family of plans) whose aggregate investment in Institutional Class shares of a fund equals or exceeds the minimum initial investment amount but where an individual plan account or program may not on its own meet such minimum amount.

Contact your financial representative to obtain a new account application or for instructions about how to set up a new account. Your financial representative can also assist with making additional investments into an existing account.

On the Internet

Register at dws.com to establish a new account (Class S shares only) or to set up online access to your existing account(s), or log in to the Web site if you have previously registered. Follow the instructions on the Web site to request a purchase with money from the bank account you established on your DWS fund account(s). Electronic purchases via the Automated Clearing House system (ACH) generally take two to three days to be completed and there is a $250,000 maximum. If establishing a new account online, you can also elect to make your initial investment by mailing a check to the address provided in the new account application process.

By Mail or Expedited Mail

To establish an account, simply complete the appropriate account application and mail it to the address provided on the form. With your application, include your check made payable to “DWS Funds” for the required initial minimum investment for the share class you have selected.

Once your account is established, to make additional investments, send a check made payable to “DWS Funds” and an investment slip to the appropriate address. If you do not have an investment slip, include a letter with your name, address, account number, the full fund name and share class, and your investment instructions. If your check fails to clear, the fund has the right to cancel your order, hold you liable or charge you or your account for any losses or fees the fund or its agents have incurred.

By Automatic Investment Plan (not available for Institutional Class)

If you wish to take advantage of the lower initial investment minimums by establishing an Automatic Investment Plan, make sure to complete that section on the new account application. If you are establishing an account by mail you will need to attach a voided check for the bank account from which the funds will be drawn. Subsequent investments are made automatically from the shareholder’s account at a bank, savings and loan or credit union into the shareholder’s DWS fund account. The maximum Automatic Investment Plan investment is $250,000. Termination by a shareholder will become effective within thirty days after DWS has received the request. Each fund may immediately terminate a shareholder’s Automatic Investment Plan in the event that any item is unpaid by the shareholder’s financial institution.

Other Ways to Buy Additional Shares

The following privileges must be established on your account before a request can be made to purchase additional shares. This can either be done by completing the applicable section(s) on the account application when you establish your account or by contacting a customer service representative for instructions.

How to Buy, Sell and Exchange Class R Shares

If your plan sponsor has selected Class R shares as an investment option, you may buy Class R shares through your securities dealer or through any financial institution that is authorized to act as a shareholder servicing agent (“shareholder servicing agent”) for your plan. Please contact your shareholder servicing agent for more information on how to open a fund account and for details on how to buy, sell and exchange Class R shares. Shareholder servicing agents include brokers, financial representatives or any other bank, dealer or other institution that have a sub-shareholder servicing agreement with the funds.

Shareholder servicing agents may charge additional fees to investors for those services not otherwise included in their sub-distribution or servicing agreement, such as cash management or special trust or retirement investment reporting. In addition, the Advisor or administrator may provide compensation to shareholder servicing agents for distribution, administrative and promotional services.

There is no minimum investment with respect to Class R shares.

Instructions for buying and selling shares must generally be submitted by a retirement plan administrator, not by plan participants for whose benefit the shares are held.

IRA rollovers. You may complete a direct rollover from a retirement plan offering Class R shares to a DWS IRA account by reinvesting up to the full amount of your distribution in Class A, Class C or Class S shares of any DWS fund. Reinvestment into Class A shares will be at net asset value, and subsequent purchases of Class A shares will be made at the public offering price as described in the

prospectus for Class A shares. Please note that if you terminate your participation in a retirement plan and transfer all of your Class R shares, you will lose the privilege of purchasing Class R shares in the future. Rollovers to a DWS Class R share IRA are not permitted.

How to Buy, Sell and Exchange Class R6 Shares

If your qualifying plan or program sponsor has selected Class R6 shares as an investment option, you may buy Class R6 shares through your securities dealer or through any financial institution that is authorized to act as a shareholder servicing agent for your plan or program. Please contact your shareholder servicing agent for more information on how to open a fund account and for details on how to buy, sell and exchange Class R6 shares.

Shareholder servicing agents may charge additional fees to investors for those services, such as cash management or special trust or retirement investment reporting. In addition, the Advisor, the Distributor and/or their affiliates may pay, out of their own respective assets, and not as an additional charge to a fund, various recordkeeping, administrative and/or other fees to selected retirement plan platform providers and recordkeepers, for services provided with respect to Class R6 shares of the fund included on such platforms (see the “Financial Intermediary Support Payments” section of the prospectus for more information).

There is no minimum investment with respect to Class R6 shares.

Instructions for buying, selling and exchanging shares must generally be submitted by a qualifying plan or program administrator, not by plan or program participants for whose benefit the shares are held.

IRA rollovers. You may complete a direct rollover from a retirement plan offering Class R6 shares to a DWS IRA account by reinvesting up to the full amount of your distribution in Class A, Class C or Class S shares of any DWS fund. Reinvestment into Class A shares will be at net asset value, and subsequent purchases of Class A shares will be made at the public offering price as described in the prospectus for Class A shares. Please note that if you terminate your participation in a retirement plan and transfer all of your Class R6 shares, you will lose the privilege of purchasing Class R6 shares in the future.

Policies You Should Know About

Along with the information on the previous pages, the policies below may affect you as a shareholder. Some of this information, such as the section on distributions and taxes, applies to all investors, including those investing through a financial representative.

Prospectus May 1, 2025

Investing in the Funds

If you are investing through a financial representative or through a retirement plan, check the materials you received from them about how to buy and sell shares because particular financial representatives or other intermediaries may adopt policies, procedures or limitations that are separate from those described in this prospectus. Please note that a financial representative or other intermediary may charge fees separate from those charged by a fund and may be compensated by a fund.

Policies About Transactions

Each fund is open for business each day the New York Stock Exchange is open. Each fund calculates its share price for each class every business day, as of the close of regular trading on the New York Stock Exchange (typically 4:00 p.m. Eastern time, but sometimes earlier, as in the case of scheduled half-day trading, shortened trading hours due to emergency circumstances or unscheduled suspensions of trading). You can place an order to buy or sell shares at any time. All transactions are processed at the share price next calculated after the order or instruction is received in “good order.” (See “How each Fund Calculates Share Price.”)

An order to buy or sell shares received in good order prior to the close of regular trading on the New York Stock Exchange, on a day each fund is open for business, will generally be effected at the share price calculated that day. An order received in good order after such time will generally be effected at the share price calculated on the next business day. A temporary intraday suspension or disruption of regular trading on the New York Stock Exchange will not be treated as the close of regular trading for that day if trading resumes and therefore will not impact the time at which each fund calculates its share price on that day. In the event of an early close of regular trading on the New York Stock Exchange, such as in the case of scheduled half-day trading, shortened trading hours due to emergency circumstances or unscheduled suspensions of trading, each fund will calculate its share price as of the early close on that day. In such event, an order received in good order before the early close will generally be effected at the share price calculated that day and an order received in good order after the early close will generally be effected at the share price calculated on the next business day.

In accordance with requirements under anti-money laundering regulations, we may request additional information and/or documents to verify your identity. This information includes, but is not limited to, your name, address, date of birth and other identifying documentation. If after reasonable effort we are unable to obtain this information to verify your identity, in accordance with federal regulations, within the time frames established by each fund, we will provide you with written notification and we may reject your application and order.

Because orders placed through a financial representative must be forwarded to the transfer agent, you’ll need to allow extra time for your order to be processed. Your financial representative should be able to tell you approximately when your order will be processed. It is the responsibility of your financial representative to forward your order to the transfer agent in a timely manner.

In the exercise of its sole discretion, each fund at any time may, without prior notice, refuse, cancel, limit or rescind any purchase; cancel or rescind any purchase order placed through a financial intermediary no later than the business day after the order is received by the financial intermediary; freeze account activity; suspend account services; and/or involuntarily redeem and close an existing account. Specifically, each fund reserves the right to involuntarily redeem an account (i) in case of actual or suspected fraudulent, illegal or suspicious activity by the account owner or any other individual associated with the account; or (ii) if the account owner fails to provide legally required information, including information and/or documentation related to identity verification, to each fund. Each fund is not required to provide justification to a potential or existing shareholder for taking any such action. Please be advised that if a fund involuntarily redeems and closes your account, under tax laws, you may be required to recognize a gain or a loss or otherwise incur tax consequences.

With certain limited exceptions, only US residents may invest in each fund.

Good order. We reserve the right to reject any order or instruction that is not in “good order.” Good order generally means that the order or instruction:

■

is complete and accurate (e.g., includes the account number, fund name, and amount of the transaction);

■

is provided by a person authorized to act for your account;

■

is accompanied by any required signatures, including signature guarantees or notarized signatures; and

■

is accompanied by any required supporting documentation.

Good order requirements are established by the fund or the transfer agent, depend on the type of account or transaction, and may be changed or waived at any time. Contact DWS if you have any questions.

Sub-Minimum Balances for Class A and C. Each fund may close your account and send you the proceeds if your balance falls below $1,000 ($500 for accounts with an Automatic Investment Plan funded with $50 or more per month in subsequent investments), or below $250 for retirement accounts. We will give you 60 days’ notice (90 days for retirement accounts) so you can either increase your balance or close your account (these policies don’t apply to investors with $100,000 or more in DWS fund shares, investors in certain fee-based and wrap programs offered through certain financial intermediaries

approved by the Advisor, or group retirement plans and certain other accounts having lower minimum share balance requirements).

Sub-Minimum Balances for Institutional Class. Each fund may redeem your shares and close your account on 60 days’ notice if it fails to meet the minimum account balance requirement of $1,000,000 for any reason.

Sub-Minimum Balances for Class S. Each fund may close your account and send you the proceeds if your balance falls below $2,500 ($1,000 with an Automatic Investment Plan funded with $50 or more per month in subsequent investments); or below $250 for retirement accounts. We will give you 60 days’ notice (90 days for retirement accounts) so you can either increase your balance or close your account (these policies don’t apply to investors with $100,000 or more in DWS fund shares, investors in certain fee-based and wrap programs offered through certain financial intermediaries approved by the Advisor, or group retirement plans and certain other accounts having lower minimum share balance requirements).

Account Maintenance Fee for Classes A, C and S. Each fund charges a $20 account maintenance fee for each fund account that has a balance below $10,000. Except as otherwise noted below, fund accounts are not aggregated by share class or fund. The assessment will occur once per calendar year and may be assessed through the automatic redemption of fund shares in your account. The fee will be assessed on each fund account that falls below the minimum for any reason, including market value fluctuations, redemptions or exchanges.

The account maintenance fee will not apply to: (i) accounts with an automatic investment plan; (ii) accounts held in an omnibus account through a financial intermediary; (iii) accounts maintained on behalf of participants in certain fee-based and wrap programs offered through certain financial intermediaries approved by the Advisor; (iv) participant level accounts in group retirement plans held on the records of a retirement plan record keeper; (v) accounts held by shareholders who maintain $50,000 or more in aggregate assets in DWS fund shares; (vi) shareholders who consent to electronic delivery for all documents (which include statements, prospectuses, annual and semi-annual reports, and other materials), except for tax forms; (vii) Uniform Gift to Minors (UGMA) and Uniform Transfer to Minors (UTMA) accounts; (viii) Coverdell Education Savings Account (ESA) accounts; and (ix) IRA accounts for shareholders beginning in the year in which they reach the applicable age for required minimum distributions under the Internal Revenue Code. You may elect to receive electronic delivery of DWS fund materials by registering on dws.com, by using the mobile app or by calling the telephone number on the back cover.

Overnight delivery of DWS fund materials. You may request to receive a paper copy of any DWS fund materials via overnight delivery by calling the telephone number

on the back cover. If you request an overnight delivery you will be charged a $20 fee ($25 for Saturday delivery) for each request, which will be paid by redeeming a portion of your shares equal to the amount of the fee. Overnight delivery is not available to a P.O. Box.

Market timing policies and procedures. Short-term and excessive trading of fund shares may present risks to long-term shareholders, including potential dilution in the value of fund shares, interference with the efficient management of a fund’s portfolio (including losses on the sale of investments), taxable gains to remaining shareholders and increased brokerage and administrative costs. These risks may be more pronounced if a fund invests in certain securities, such as those that trade in foreign markets, are illiquid or do not otherwise have “readily available market quotations.” Certain investors may seek to employ short-term trading strategies aimed at exploiting variations in portfolio valuation that arise from the nature of the securities held by a fund (e.g., “time zone arbitrage”). Each fund discourages short-term and excessive trading and has adopted policies and procedures that are intended to detect and deter short-term and excessive trading.

Each fund also reserves the right to reject or cancel a purchase or exchange order for any reason without prior notice. For example, a fund may in its discretion reject or cancel a purchase or an exchange order even if the transaction is not subject to the transaction limitation described below if the Advisor believes that there appears to be a pattern of short-term or excessive trading activity by a shareholder or deems any other trading activity harmful or disruptive to a fund. Each fund, through its Advisor and transfer agent, will monitor changes in investment direction (CID) transactions that exceed a certain dollar amount by a shareholder within a fund within a specified time period. A CID transaction is a transaction opposite to the prior transaction, which can be a purchase, redemption or exchange of the same fund. Each fund may take other trading activity into account if a fund believes such activity is of an amount or frequency that may be harmful to long-term shareholders or disruptive to portfolio management. The Advisor’s practices for identifying excessive short-term trading activity (e.g., the number of CID transactions, the dollar threshold and the time period) may change from time to time. If the Advisor determines that an investor has engaged in excessive short-term trading, the Advisor may issue the shareholder and/or the shareholder’s financial intermediary, if any, a written warning and/or may block the shareholder from further purchases of or exchanges into the fund’s shares.

Each fund reserves the right to maintain a block indefinitely if it deems that the shareholder’s activity was harmful to a fund, or that the pattern of activity suggests a pattern of abuse. The rights of a shareholder to redeem shares of a DWS fund are not affected by a block on purchases and exchanges.

Prospectus May 1, 2025

Investing in the Funds

Each fund may make exceptions to the transaction policy for certain types of transactions if, in the opinion of the Advisor, the transactions do not represent short-term or excessive trading or are not abusive or harmful to a fund, such as, but not limited to, systematic transactions, required minimum retirement distributions, transactions initiated by a fund or administrator and transactions by certain qualified funds-of-funds.

In certain circumstances where shareholders hold shares of a fund through a financial intermediary, a fund may rely upon the financial intermediary’s policy to deter short-term or excessive trading if the Advisor believes that the financial intermediary’s policy is reasonably designed to detect and deter transactions that are not in the best interests of a fund. A financial intermediary’s policy relating to short-term or excessive trading may be more or less restrictive than the DWS funds’ policy, may permit certain transactions not permitted by the DWS funds’ policies, or prohibit transactions not subject to the DWS funds’ policies.

The Advisor may also accept undertakings from a financial intermediary to enforce short-term or excessive trading policies on behalf of a fund that provide a substantially similar level of protection for each fund against such transactions. For example, certain financial intermediaries may have contractual, legal or operational restrictions that prevent them from blocking an account. In such instances, the financial intermediary may use alternate techniques that the Advisor considers to be a reasonable substitute for such a block.

In addition, if a fund invests some portion of its assets in foreign securities, it has adopted certain fair valuation practices intended to protect the fund from “time zone arbitrage” with respect to its foreign securities holdings and other trading practices that seek to exploit variations in portfolio valuation that arise from the nature of the securities held by a fund. (See “How each Fund Calculates Share Price.”)

There is no assurance that these policies and procedures will be effective in limiting short-term and excessive trading in all cases. For example, the Advisor may not be able to effectively monitor, detect or limit short-term or excessive trading by underlying shareholders that occurs through omnibus accounts maintained by broker-dealers or other financial intermediaries. The Advisor reviews trading activity at the omnibus level to detect short-term or excessive trading. If the Advisor has reason to suspect that short-term or excessive trading is occurring at the omnibus level, the Advisor will contact the financial intermediary to request underlying shareholder level activity. Depending on the amount of fund shares held in such omnibus accounts (which may represent most of a fund’s shares), short-term and/or excessive trading of fund shares could adversely affect long-term shareholders in a fund. If short-term or excessive trading is identified, the Advisor will take appropriate action.

Each fund’s market timing policies and procedures may be modified or terminated at any time.

Purchase and redemption orders may be placed at any time, but will only be processed during normal business hours on business days, as detailed in this prospectus. Not all transactions are eligible for processing online or through the mobile app. The ability to open new accounts online or through the mobile app is available only to accounts that are established directly with each fund’s transfer agent, and is limited to certain account types and share classes. Processing certain transactions or opening certain types of accounts may require you to obtain, complete and mail the appropriate form.

When registering online at dws.com or through the mobile app, you will be asked to accept certain terms and conditions, create a user profile and establish a password. The same user profile and password will provide both online and mobile app access. Accessing your fund account and transacting online or through the mobile app requires the transmission of personal financial information over the Internet and/or a mobile data network, and is not without risk. Digital communication channels such as those described above are not necessarily secure and are subject to the risk, among others, that any confidential or sensitive information that you send or view may be intercepted or accessed by a third party and subsequently sold or used, including for instance, to gain access to your fund account and redeem shares. We recommend that you take steps to protect your account information, including the use of a secure Internet browser, keeping user IDs and passwords confidential, and taking steps to restrict access to your computer and mobile devices. As long as we follow reasonable security procedures and act on instructions that we reasonably believe are genuine, we will not be responsible for any losses that may occur from unauthorized requests. Each fund may modify, suspend, or terminate online or mobile account access or services at any time.

During periods of extreme volume that may result from dramatic economic or stock market events, it is possible that you may have difficulty accessing your account online or using the mobile app. Your online account and/or the mobile app may be unavailable during certain periods due to unforeseen technology issues or for other reasons such as routine maintenance or updates. If you are unable to access your account online or using the mobile app you can reach DWS by mail or by telephone (see contact information on the back cover).

Telephone transactions. Generally, you are automatically entitled to telephone redemption and exchange privileges, but you may elect not to have them when you open your account (paper applications only) or by calling the appropriate telephone number on the back cover.

Transactions by telephone are not without risk. We recommend that you take steps to protect your account information. As long as we follow reasonable security procedures and act on instructions received over the telephone that we reasonably believe are genuine, we will not be responsible for any losses that may occur from unauthorized requests.

During periods of extreme volume that may result from dramatic economic or stock market events or due to unforeseen technology issues, it is possible that you may have difficulty reaching DWS by phone. If you are unable to reach us by phone you may be able to view account information or request transactions online or using the mobile app, or you can mail inquiries to DWS at the address on the back cover.

Responsibility for fraud. Each fund and its service providers, including DWS, shall not be liable for any loss incurred by reason of a fund accepting unauthorized transaction requests for your account if the fund reasonably believes the instructions to be genuine. In order to safeguard your account, you should keep all account information private and review all confirmation statements and other account-related communications as soon as you receive them. We will consider all transactions to be properly processed if discrepancies are not reported promptly. Contact us immediately if you suspect that someone has gained unauthorized access to your account. The DWS Account Security Program provides further information on how you can protect your account. Visit the Investor Resource Center at dws.com for more information.

Each fund does not issue share certificates. However, if you currently have shares in certificated form, you must include the share certificates properly endorsed or accompanied by a duly executed stock power when exchanging or redeeming shares. You may not exchange or redeem shares in certificate form by telephone, via the Internet or using the mobile app.

When you ask us to send or receive a wire, please note that while we don’t charge a fee to send or receive wires, it’s possible that your bank may do so. Wire transactions are generally completed within 24 hours. Each fund can only send wires of $1,000 or more and accept wires of $50 or more.

Each fund accepts payment for shares only in US dollars by a check drawn on a US bank, a bank or Federal Funds wire transfer or an electronic bank transfer. Each fund does not accept third party checks. A third party check is a check made payable to one or more parties and offered as payment to one or more other parties (e.g., a check made payable to you that you offer as payment to someone else). Checks should be payable to “DWS Funds” and drawn by you or a financial institution on your behalf with your name or account number included with the check. If you pay for shares by check and the check fails to clear, we have the right to cancel your order, hold you liable or charge you or your account for any losses or fees each fund or its agents have incurred.

Signature Guarantee. When you want to sell more than $100,000 worth of shares or send proceeds to a third party or to a new address, you’ll usually need to place your order in writing and have your signature guaranteed. However, if you want money transferred electronically to a bank account that is already on file with us, you don’t need a signature guarantee (but other limits may apply). Also, generally you don’t need a signature guarantee for an exchange, although we may require one in certain other circumstances.

A signature guarantee is a certification of your signature — a valuable safeguard against fraud. Each fund accepts Medallion Signature Guarantees, which can be obtained from an eligible guarantor. Eligible guarantor institutions include commercial banks, savings and loans, trust companies, credit unions, member firms of a national stock exchange or any member or participant of an approved signature guarantor program. A signature guarantee cannot be provided by a notary public.

Selling shares of trust accounts and business or organization accounts may require additional documentation. Please call DWS (see the telephone number on the back cover) or contact your financial representative for more information.

When you sell shares that have a CDSC, the CDSC is based on the original purchase cost or current market value of the shares sold, whichever is less. In processing orders to sell shares, the shares with the lowest CDSC are sold first. For each investment you make, we use the first day of the month in which you bought shares to calculate a CDSC on that particular investment. A CDSC is not imposed when you exchange from one fund into another, however, shares of the fund acquired in an exchange that were subject to a CDSC at the time of the exchange will continue to be subject to the CDSC schedule of the shares of the fund you originally purchased.

Investing in the Funds

If you sell shares in a DWS fund for which you paid a sales charge and then decide to invest with DWS again within six months, you may be able to take advantage of the “reinstatement feature.” With this feature, you can put your money back into the same class of a DWS fund at its current net asset value and, for purposes of a sales charge, it will be treated as if it had never left DWS (this may result in a tax liability for federal income tax purposes). You'll be reimbursed (in the form of fund shares by the Distributor) for any CDSC you paid when you sold shares in a DWS fund. Future CDSC calculations will be based on your original investment date, rather than your reinstatement date.

You can only use the reinstatement feature once for any given group of shares. To take advantage of this feature, contact Shareholder Services or your financial representative.

Class A to Institutional Class in the Same Fund Exchange Privilege. Investors who have invested in Class A shares through a comprehensive or “wrap” fee program or other fee-based program sponsored by a broker-dealer, bank or registered investment adviser or who are transferring to such a program may potentially become eligible to invest in Institutional Class shares by reason of their participation in such a program. In such event, subject to the discretion of the Distributor and the limitations noted below, such shareholders may exchange their Class A shares for Institutional Class shares of equal aggregate value of the same fund. No sales charges or other charges will apply to any such exchange. Exchanges under this privilege will generally be processed only as part of a pre-arranged, multiple-client transaction through the particular financial services firm offering the comprehensive or wrap program or other fee-based program where the Institutional Class shares are available. DDI may agree with financial intermediaries to allow this exchange privilege outside of pre-arranged, multiple-client transactions. Investors should contact their selling and/or servicing agents to learn more about the details of this exchange feature. Shareholders generally will not recognize a gain or loss for federal income tax purposes upon the exchange of Class A shares of a fund for Institutional Class shares of the same fund.

Class A to Class S in the Same Fund Exchange Privilege. Investors who have invested in Class A shares through a comprehensive or “wrap” fee program or other fee-based program sponsored by a broker-dealer, bank or registered investment adviser or who are transferring to such a program may become eligible to invest in Class S shares. Subject to the discretion of the Distributor, such shareholders may exchange their Class A shares for Class S shares of equal aggregate value of the same fund.

exchange feature. Shareholders generally will not recognize a gain or loss for federal income tax purposes upon the exchange of Class A shares of a fund for Class S shares of the same fund.

Class C to Class A, Class S or Institutional Class in the Same Fund Exchange Privilege. Investors who either (i) have invested in Class C shares through a comprehensive or “wrap” fee program or other fee-based program sponsored by a broker-dealer, bank or registered investment adviser or (ii) have invested in Class C shares and are in the process of transferring their shares to such a program may potentially become eligible to invest in either Class A shares, Class S shares or Institutional Class shares by reason of their participation in such a program. In addition, investors who have invested in Class C shares as part of an Employer-Sponsored Retirement Plan or an Employer-Sponsored IRA may potentially become eligible to invest in Class A shares by reason of their investment in such Employer Sponsored Retirement Plan or Employer-Sponsored IRA. In such event, subject to the discretion of the Distributor and the limitations noted below, such shareholders may exchange their Class C shares for Class A shares, Class S shares or Institutional Class shares (as applicable) of equal aggregate value of the same fund. No sales charges or other charges will apply to any such exchange. Exchanges under this privilege will generally be processed only in instances where the accounts are not currently subject to a CDSC and only as part of a pre-arranged, multiple-client transaction through the particular financial services firm offering the comprehensive or wrap program or other fee-based program or involving the Employer-Sponsored Retirement Plan or Employer-Sponsored IRA where the Class A shares, Class S shares or Institutional Class shares (as applicable) are available. DDI may agree with financial intermediaries to allow this exchange privilege for accounts currently subject to a CDSC and outside of pre-arranged, multiple-client transactions. In such situations, the financial intermediary may reimburse DDI for a portion of any CDSC that DDI would have otherwise collected on the transaction or a portion of the distribution fees previously advanced by DDI to the financial intermediary in connection with the initial sale of the Class C shares. Investors should contact their selling and/or servicing agents to learn more about the details of this exchange feature. Shareholders generally will not recognize a gain or loss for federal income tax purposes upon the exchange of Class C shares of a fund for Class A shares, Class S shares or Institutional Class shares of the same fund.

Class S to Institutional Class in the Same Fund Exchange Privilege. Investors who have invested in Class S shares through a comprehensive or “wrap” fee program or other fee-based program sponsored by a broker-dealer, bank or registered investment adviser or who are transferring to such a program may potentially become eligible to invest in Institutional Class shares by reason of their participation in such a program.

to the discretion of the Distributor and the limitations noted below, such shareholders may exchange their Class S shares for Institutional Class shares of equal aggregate value of the same fund. No sales charges or other charges will apply to any such exchange. Exchanges under this privilege will generally be processed only as part of a pre-arranged, multiple-client transaction through the particular financial services firm offering the comprehensive or wrap program or other fee-based program where the Institutional Class shares are available. DDI may agree with financial intermediaries to allow this exchange privilege outside of pre-arranged, multiple-client transactions. Investors should contact their selling and/or servicing agents to learn more about the details of this exchange feature. Shareholders generally will not recognize a gain or loss for federal income tax purposes upon the exchange of Class S shares of a fund for Institutional Class shares of the same fund.

Class S or Institutional Class to Class A in the Same Fund Exchange Privilege. Exchanges by a financial intermediary of Class S or Institutional Class shares for Class A shares of the same fund are allowed without the imposition of a sales charge in connection with a change in account type or otherwise in accordance with the intermediary’s policies and procedures that renders a shareholder ineligible for Class S or Institutional Class shares. The availability of this exchange privilege and sales charge waiver depends on the policies, procedures and trading platforms of the intermediary. Investors should contact their financial intermediary to learn more about the details of this exchange feature. Shareholders generally will not recognize a gain or loss for federal income tax purposes upon the exchange of Class S or Institutional Class shares of a fund for Class A shares of the same fund.

Class A, Class R, Class S or Institutional Class to Class R6 in the Same Fund Exchange Privilege. Investors who have invested in Class A, Class R, Class S or Institutional Class shares through either a retirement plan platform or a college savings plan under Section 529 of the Internal Revenue Code with plan-level or omnibus accounts held on the books of the fund may potentially become eligible to invest in Class R6 shares by reason of their participation in such plans. Exchanges under this privilege are subject to the discretion of the Distributor and will be processed only as part of a prearranged, plan-level transaction with a qualifying plan program or college savings plan under Section 529 of the Internal Revenue Code. If an exchange by a qualifying plan program or a college savings plan under Section 529 of the Internal Revenue Code is approved, investors holding Class A, Class R, Class S or Institutional Class shares through such plan will exchange those shares for Class R6 shares of equal aggregate value of the same fund. No sales charges or other charges will apply to any such exchange. Investors should contact their plan servicing agents to learn more about the details of this exchange feature. Shareholders generally will not recognize a gain or loss for

federal income tax purposes upon the exchange of Class A, Class R, Class S or Institutional Class shares of a fund for Class R6 shares of the same fund.

Institutional Class Exchange Privilege. The following persons may, subject to certain limitations, exchange Institutional Class shares for DWS Money Market Fund shares of DWS Money Market Prime Series: (1) a current or former director or trustee of DWS mutual funds; and (2) an employee, the employee’s spouse or life partner and children or stepchildren age 21 or younger of Deutsche Bank AG or its affiliates or a subadvisor to any fund in the DWS mutual fund family or a broker-dealer authorized to sell shares of the DWS mutual funds.

Money from shares you sell is normally sent out within one business day of when your request is received in good order, regardless of the method of payment (e.g. check, wire, ACH) although it could be delayed for up to seven days. There are circumstances when it could be longer, including, but not limited to, when you are selling shares you bought recently by check or ACH (the funds will be placed under a 10 calendar day hold to ensure good funds) or when unusual circumstances prompt the SEC to allow further delays. Certain expedited redemption processes (e.g., redemption proceeds by wire) may also be delayed or unavailable when you are selling shares recently purchased or in the event of the closing of the Federal Reserve wire payment system.

Redemptions will generally be in the form of cash, though a fund reserves the right to redeem in kind (as described under “Other Rights We Reserve”). Each fund typically expects to satisfy redemption requests by using available cash or by selling portfolio securities if available cash is not sufficient to meet redemptions. Each fund may utilize an existing line of credit for temporary coverage in the event of a cash shortfall. Each fund may also utilize inter-fund lending, though such use is expected to be rare. Each fund may use any of these methods of satisfying redemption requests under normal or stressed market conditions. During periods of distressed market conditions, when a significant portion of a fund’s portfolio may be comprised of less-liquid and/or illiquid investments, a fund may be more likely to pay redemption proceeds by giving you securities.

Each fund reserves the right to suspend or postpone redemptions as permitted pursuant to Section 22(e) of the Investment Company Act of 1940 (the “1940 Act”). Generally, those circumstances are when 1) the New York Stock Exchange is closed other than customary weekend or holiday closings; 2) the SEC determines that trading on the New York Stock Exchange is restricted; 3) the SEC determines that an emergency exists which makes the disposal of securities owned by a fund or the fair determination of the value of a fund’s net assets not reasonably practicable; or 4) the SEC, by order, permits the suspension of the right of redemption. Redemption payments by wire may also be delayed in the event of a non-routine closure of the

Federal Reserve wire payment system. For additional rights reserved by each fund, please see “Other Rights We Reserve.”

How each Fund Calculates Share Price

To calculate net asset value, or NAV, each share class uses the following equation:

(

Total

Assets

−

Total

Liabilities

)

Total Number of

Shares Outstanding

NAV

The price at which you buy shares is based on the NAV per share calculated after the order is received and accepted by the transfer agent, although for Class A shares it will be adjusted to allow for any applicable sales charge (see “Choosing a Share Class”). The price at which you sell shares is also based on the NAV per share calculated after the order is received and accepted by the transfer agent, although a CDSC may be taken out of the proceeds (see “Choosing a Share Class”). To obtain the fund's most recent share price, go to dws.com (the Web site does not form a part of this prospectus) or call the telephone number included in this prospectus.

The Board has designated the Advisor as the valuation designee for each fund pursuant to Rule 2a-5 under the 1940 Act. The Advisor’s Pricing Committee typically values securities using readily available market quotations or prices supplied by independent pricing services (which are considered fair values under Rule 2a-5). The Advisor has adopted fair valuation procedures that provide methodologies for fair valuing securities when pricing service prices or market quotations are not readily available, including when a security’s value or a meaningful portion of the value of a fund's portfolio is believed to have been materially affected by a significant event, such as a natural disaster, an economic event like a bankruptcy filing, or a substantial fluctuation in domestic or foreign markets that has occurred between the close of the exchange or market on which the security is principally traded (for example, a foreign exchange or market) and the close of the New York Stock Exchange. In such a case, a fund’s value for a security is likely to be different from the last quoted market price or pricing service prices. In addition, due to the subjective and variable nature of fair value pricing, it is possible that the value determined for a particular asset may be materially different from the value realized upon such asset’s sale.

It is expected that the greater the percentage of fund assets that is invested in non-US securities, the more extensive will be a fund’s use of fair value pricing. This is intended to reduce a fund’s exposure to “time zone arbitrage” and other harmful trading practices. (See “Market timing policies and procedures.”)

To the extent that a fund invests in securities that are traded primarily in foreign markets, the value of its holdings could change at a time when you aren’t able to buy or sell fund shares. This is because some foreign markets

are open on days or at times when a fund doesn’t price its shares. (Note that prices for securities that trade on foreign exchanges can change significantly on days when the New York Stock Exchange is closed and you cannot buy or sell fund shares. Price changes in the securities a fund owns may ultimately affect the price of fund shares the next time the NAV is calculated.)

Other Rights We Reserve

You should be aware that we may do any of the following:

■

withdraw or suspend the offering of shares at any time

■

withhold a portion of your distributions and redemption proceeds if we have been notified by the Internal Revenue Service that you are subject to backup withholding, if you fail to provide us with the correct taxpayer ID number and certain certifications, including certification that you are not subject to backup withholding, or if you are otherwise subject to withholding

■

reject an account application if you don’t provide any required or requested identifying information, or for any other reason

■

without prior notice, refuse, cancel, limit or rescind any purchase or exchange order; freeze any account (meaning you will not be able to purchase fund shares in your account); suspend account services; and/or involuntarily redeem and close your account if we think that the account is being used for fraudulent or illegal purposes; one or more of these actions will be taken when, at our sole discretion, they are deemed to be in a fund’s best interests or when a fund is requested or compelled to do so by governmental authority or by applicable law

■

close and liquidate your account if we are unable to verify your identity, or for other reasons; if we decide to close your account, your fund shares will be redeemed at the net asset value per share next calculated after we determine to close your account (less any applicable sales charges or CDSC); you may recognize a gain or loss on the redemption of your fund shares and you may incur a tax liability

■

pay you for shares you sell by “redeeming in kind,” that is, by giving you securities (which are subject to market risk until sold, may incur taxes and typically will involve brokerage costs for you to liquidate) rather than cash, but which will be taxable to the same extent as a redemption for cash; a fund generally won’t make a redemption in kind unless your requests over a 90-day period total more than $250,000 or 1% of the value of a fund’s net assets, whichever is less

■

change, add or withdraw various services, fees and account policies (for example, we may adjust a fund’s investment minimums at any time)

Financial Intermediary Support Payments

The Advisor, the Distributor and/or their affiliates may pay additional compensation, out of their own assets and not as an additional charge to each fund, to selected affiliated and unaffiliated brokers, dealers, participating insurance companies or other financial intermediaries (“financial representatives”) in connection with the sale and/or distribution of fund shares or the retention and/or servicing of fund investors and fund shares (“revenue sharing”). Such revenue sharing payments are in addition to any distribution or service fees payable under any Rule 12b-1 or service plan of each fund, any recordkeeping/sub-transfer agency/networking fees payable by each fund (generally through the Distributor or an affiliate) and/or the Distributor or Advisor to certain financial representatives for performing such services and any sales charges, commissions, non-cash compensation arrangements expressly permitted under applicable rules of the Financial Industry Regulatory Authority or other concessions described in the fee table or elsewhere in this prospectus or the Statement of Additional Information as payable to all financial representatives. For example, the Advisor, the Distributor and/or their affiliates may, using their legitimate profits, compensate financial representatives for providing a fund with “shelf space” or access to a financial representative’s platform (including the costs associated with establishing and maintaining the fund on such platform) or fund offering list or other marketing programs, including, without limitation, inclusion of the fund on preferred or recommended sales lists, mutual fund “supermarket” platforms and other formal sales programs; granting the Distributor access to the financial representative’s sales force; granting the Distributor access to the financial representative’s conferences and meetings; assistance in training and educating the financial representative’s personnel; and obtaining other forms of marketing support. In addition, revenue sharing payments may consist of the Distributor’s and/or its affiliates’ payment or reimbursement of ticket charges that would otherwise be assessed by a financial representative on an investor’s fund transactions. In some cases, financial representatives may determine to credit all or a portion of revenue sharing payments back to investors.

The level of revenue sharing payments made to financial representatives may be a fixed fee or based upon one or more of the following factors: gross sales, current assets and/or number of accounts of each fund attributable to the financial representative, the particular fund or fund type or other measures as agreed to by the Advisor, the Distributor and/or their affiliates and the financial representatives or any combination thereof. The amount of these payments is determined at the discretion of the Advisor, the Distributor and/or their affiliates from time to time, may be substantial, and may be different for different financial representatives based on, for example, the nature of the services provided by the financial representative.

The Advisor, the Distributor and/or their affiliates currently make revenue sharing payments from their own assets in connection with the sale and/or distribution of DWS fund shares or the retention and/or servicing of investors to financial representatives in amounts that generally range from 0.01% up to 0.25% of assets of each fund serviced and maintained by the financial representative, 0.05% to 0.25% of sales of each fund attributable to the financial representative, a flat fee of up to $95,000, or any combination thereof. These amounts are annual figures typically paid on a quarterly basis and are subject to change at the discretion of the Advisor, the Distributor and/or their affiliates. Receipt of, or the prospect of receiving, this additional compensation may influence your financial representative’s recommendation of each fund or of any particular share class of each fund. You should review your financial representative’s compensation disclosure and/or talk to your financial representative to obtain more information on how this compensation may have influenced your financial representative’s recommendation of each fund. Additional information regarding these revenue sharing payments is included in each fund’s Statement of Additional Information, which is available to you on request at no charge (see the back cover of this prospectus for more information on how to request a copy of the Statement of Additional Information).

The Advisor, the Distributor and/or their affiliates may also make such revenue sharing payments to financial representatives under the terms discussed above in connection with the distribution of both DWS funds and non-DWS funds by financial representatives to retirement plans that obtain recordkeeping services from ADP, Inc. or to 403(b) plans that obtain recordkeeping services from Ascensus, Inc. on the DWS-branded retirement plan platform (the “Platform”). The level of revenue sharing payments is based upon sales of both the DWS funds and the non-DWS funds by the financial representative on the Platform or current assets of both the DWS funds and the non-DWS funds serviced and maintained by the financial representative on the Platform.

It is likely that broker-dealers that execute portfolio transactions for each fund will include firms that also sell shares of the DWS funds to their customers. However, the Advisor will not consider sales of DWS fund shares as a factor in the selection of broker-dealers to execute portfolio transactions for the DWS funds. Accordingly, the Advisor has implemented policies and procedures reasonably designed to prevent its traders from considering sales of DWS fund shares as a factor in the selection of broker-dealers to execute portfolio transactions for each fund. In addition, the Advisor, the Distributor and/or their affiliates will not use fund brokerage to pay for their obligation to provide additional compensation to financial representatives as described above.

Understanding Distributions and Taxes

Each fund intends to distribute to its shareholders virtually all of its net earnings. Each fund can earn money in two ways: by receiving interest, dividends or other income from investments it holds and by selling investments for more than it paid for them. (Each fund’s earnings are separate from any gains or losses stemming from your own purchase and sale of fund shares.) Each fund may not always pay a dividend or other distribution for a given period. As with any investment, you should consider how your investment in shares of a fund will be taxed. The US federal income tax information in this prospectus is provided as general information and summarizes only some of the important federal income tax considerations affecting a fund and you as a shareholder. You should consult your own tax professional about the federal income tax and other tax consequences of an investment in shares of a fund.

DWS RREEF Global Real Estate Securities Fund intends to pay dividends and distributions of investment income to shareholders annually. DWS RREEF Global Infrastructure Fund and DWS RREEF Real Estate Securities Fund intend to pay dividends and distributions of investment income to shareholders quarterly in March, June, September and December. Any undistributed realized capital gains are paid annually in December. Each fund may make distributions at other times as needed.

In general, your distributions are subject to US federal income tax for the year when they are paid. Dividends declared and payable to shareholders of record in the last quarter of a given calendar year are treated for federal income tax purposes as if they were received by shareholders and paid by the fund on December 31 of that year, if such dividends are actually paid in January of the following year.

For federal income tax purposes, income and capital gain dividends are generally taxable to shareholders. However, dividends, regardless of character, received by retirement plans qualifying for tax exemption under federal income tax laws generally will not be currently taxable.

You can choose how to receive your dividends, whether ordinary or capital gain dividends, and other distributions. You can have them all automatically reinvested in fund shares (at NAV), all deposited directly to your bank account or all sent to you by check, have one type reinvested and the other sent to you by check or have them invested in a different fund. Tell us your preference on your application. If you don’t indicate a preference, your dividends and distributions will all be reinvested in shares of the fund without a sales charge (if applicable). Dividends and distributions are treated the same for federal income tax purposes whether you receive them in cash or reinvest them in additional shares.

Buying, selling or exchanging fund shares will usually have federal income tax consequences for you (except in employer-sponsored qualified plans, IRAs or other tax-advantaged accounts). Your sale of shares may result in a capital gain or loss. The gain or loss will generally be long-term or short-term depending on how long you owned the shares that were sold. Your ability to deduct capital losses may be limited. For federal income tax purposes, an exchange is treated the same as a sale. In addition, if shares are redeemed to pay any account fees (e.g., an account maintenance fee), you may incur a tax liability.

The federal income tax status of a fund’s earnings you receive and transactions involving your shares generally depends on their type:

Generally taxed at net capital gain rates:	Generally taxed at ordinary income rates:
Fund distributions
■gains from the sale of securi- ties held (or treated as held) by a fund for more than one year ■qualified dividend income	■gains from the sale of securi- ties held (or treated as held) by a fund for one year or less ■all other taxable income
Transactions involving fund shares
■gains from selling fund shares held for more than one year	■gains from selling fund shares held for one year or less

Any direct investments in foreign securities by a fund may be subject to foreign withholding taxes. In that case, a fund’s yield on those securities would generally be decreased. Shareholders of DWS RREEF Real Estate Securities Fund generally will not be entitled to claim a credit or deduction with respect to foreign taxes paid by the fund. Each of DWS RREEF Global Infrastructure Fund and DWS RREEF Global Real Estate Securities Fund may elect to pass through to its shareholders a credit or deduction for foreign taxes it has paid if at the end of its fiscal year more than 50% of the value of its total assets consists of stocks or securities of foreign corporations. If this election is made, shareholders will generally be able to claim a credit or deduction (subject to certain limitations) on their federal income tax return for, and will be required to include in gross income as a distribution from a fund, their pro rata portion of the income taxes paid by a fund to foreign countries. In addition, any investments in foreign securities or foreign currencies may increase or accelerate a fund’s recognition of ordinary income and may affect the timing or amount of the fund’s distributions. If you invest in a fund through a taxable account, your after-tax return could be negatively affected.

Investments in certain debt obligations or other securities may cause a fund to recognize income in excess of the cash generated by them. Thus, a fund could be required at times to liquidate other investments in order to satisfy its distribution requirements.

Investing in the Funds

Each fund's use of derivatives, if any, may affect the amount, timing and character of distributions to shareholders and, therefore, may increase the amount of taxes payable by shareholders.

A fund's ability to pursue its investment strategy and achieve its investment objective may be limited by its intention to qualify as a regulated investment company for federal income tax purposes.

Distributions to individuals and other non-corporate shareholders of investment income reported by a fund as derived from qualified dividend income are eligible for taxation for federal income tax purposes at the more favorable net capital gain rates. Qualified dividend income generally includes dividends received by a fund from domestic and some foreign corporations. It does not include income from investments in debt securities. In addition, a fund must meet certain holding period and other requirements with respect to the dividend-paying stocks in its portfolio and the shareholder must meet certain holding period and other requirements with respect to a fund’s shares for the lower tax rates to apply.

Dividends received by a fund from a REIT may be treated as qualified dividend income only to the extent the dividends are attributable to qualified dividend income received by such REIT.

For taxable years beginning after December 31, 2017 and before January 1, 2026, qualified REIT dividends (i.e., REIT dividends other than capital gain dividends and portions of REIT dividends designated as qualified dividend income) are eligible for a 20% federal income tax deduction in the case of individuals, trusts and estates. A fund that receives qualified REIT dividends may elect to pass the special character of this income through to its shareholders. To be eligible to treat distributions from a fund as qualified REIT dividends, a shareholder must hold shares of the fund for more than 45 days during the 91-day period beginning on the date that is 45 days before the date on which the shares become ex dividend with respect to such dividend and the shareholder must not be under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property. If a fund does not elect to pass the special character of this income through to shareholders or if a shareholder does not satisfy the above holding period requirements, the shareholder will not be entitled to the 20% deduction for the shareholder’s share of the fund’s qualified REIT dividend income while direct investors in REITs may be entitled to the deduction.

Certain types of income received by a fund from REITs, real estate mortgage investment conduits (“REMICs”), taxable mortgage pools or other investments may cause a fund to designate some or all of its distributions as “excess inclusion income.” To fund shareholders such excess inclusion income may (1) constitute taxable income, as unrelated business taxable income (“UBTI”) for those shareholders who would otherwise be exempt

from federal income tax, such as individual retirement accounts, 401(k) accounts, Keogh plans, pension plans and certain charitable entities; (2) not generally be offset by net operating losses; (3) not be eligible for reduced US withholding for non-US shareholders, including shareholders from tax treaty countries; and (4) cause the fund to be subject to tax if certain “disqualified organizations” are fund shareholders.

Your fund will send you detailed federal income tax information early each year. These statements tell you the amount and the federal income tax classification of any dividends or distributions you received. They also have certain details on your purchases and sales of shares.

Because the REITs invested in by DWS RREEF Real Estate Securities Fund and DWS RREEF Global Real Estate Securities Fund do not provide complete information about the taxability of the REIT's distributions until after the calendar year-end, in order to determine how much of a fund’s distribution is taxable to shareholders, the fund may request permission from the IRS each year for an extension of time to issue Form 1099-DIV.

A 3.8% Medicare contribution tax is imposed on the “net investment income” of individuals, estates and trusts to the extent their income exceeds certain threshold amounts. For this purpose, net investment income generally includes taxable dividends, including any capital gain dividends paid by a fund, and net gains recognized on the sale, redemption or exchange of shares of a fund.

If you invest right before a fund pays a dividend, you’ll be getting some of your investment back as a dividend, which may be taxable to you. You can avoid this by investing after a fund pays a dividend. In tax-advantaged accounts you generally do not need to worry about this.

If a fund’s distributions exceed its current and accumulated earnings and profits, the excess will be treated for federal income tax purposes as a tax-free return of capital to the extent of your basis in your shares and thereafter as a capital gain. Because a return of capital distribution reduces the basis of your shares, a return of capital distribution may result in a higher capital gain or a lower capital loss when you sell your shares held in a taxable account.

Corporations are taxed at the same rates on ordinary income and capital gains but may be eligible for a dividends received deduction to the extent of the amount of eligible dividends received by a fund from domestic corporations for the taxable year, provided certain holding period and other requirements are met. Distributions received by a fund from REITs will not be eligible for the dividends received deduction.

DWS RREEF Real Estate Securities Fund and DWS RREEF Global Real Estate Securities Fund do not expect a significant portion of their distributions to be eligible for the corporate dividends received deduction.

Hypothetical Expense Summary

Using the annual fund operating expense ratios presented in the fee tables in the fund’s prospectus, the Hypothetical Expense Summary shows the estimated fees and expenses, in actual dollars, that would be charged on a hypothetical investment of $10,000 in the fund held for the next 10 years and the impact of such fees and expenses on fund returns for each year and cumulatively, assuming a 5% return for each year. The historical rate of return for the fund may be higher or lower than 5% and, for money market funds, is typically less than 5%. The tables also assume that all dividends and distributions are reinvested. The annual fund expense ratios shown are net of any contractual fee waivers or expense reimbursements, if any, for the period of the contractual commitment. The tables reflect the maximum initial sales charge, if any, but do not reflect any contingent deferred sales charge, if any, which may be payable upon redemption. If contingent deferred sales charges were shown, the “Hypothetical Year-End Balance After Fees and Expenses” amounts

shown would be lower and the “Annual Fees and Expenses” amounts shown would be higher. Also, please note that if you are investing through a third party provider, that provider may have fees and expenses separate from those of the fund that are not reflected here. Mutual fund fees and expenses fluctuate over time and actual expenses may be higher or lower than those shown.

Class C shares generally convert automatically to Class A shares after 8 years. The information presented in the Hypothetical Expense Summary for Class C reflects the conversion of Class C shares to Class A shares after 8 years. See “Class C Shares” in the “Choosing a Share Class” section of the prospectus for more information. The Hypothetical Expense Summary should not be used or construed as an offer to sell, a solicitation of an offer to buy or a recommendation or endorsement of any specific mutual fund. You should carefully review the fund’s prospectus to consider the investment objective, risks, expenses and charges of the fund prior to investing.

Sales Charge Waivers and Discounts Available Through Intermediaries

The availability of certain sales charge waivers and discounts may depend on whether you purchase your shares directly from the fund or through a financial intermediary. Intermediaries may have different policies and procedures regarding the availability of front-end sales charge waivers or contingent deferred (back-end) sales charge (“CDSC”) waivers. For waivers and discounts not available through a particular intermediary, you will have to purchase fund shares directly from the fund or through another intermediary. The financial intermediary sales charge waivers, discounts and policies disclosed in this Appendix may vary from those disclosed elsewhere in the fund’s prospectus or SAI. In all instances, it is your responsibility to notify the fund or your financial intermediary at the time of purchase of any relationship or other facts qualifying you for sales charge waivers or discounts.

The sales charge waivers, discounts and policies described below are applied by the identified financial intermediaries. Please contact the applicable intermediary with any questions regarding how the intermediary applies its waivers, discounts and policies and to ensure that you understand what steps you must take to qualify for any available waivers or discounts.

MERRILL LYNCH SALES CHARGE WAIVERS AND DISCOUNTS

Purchases or sales of front-end (i.e. Class A) or level-load (i.e. Class C) mutual fund shares through a Merrill platform or account will be eligible only for the following sales load waivers (front-end, contingent deferred, or back-end waivers) and discounts, which differ from those disclosed elsewhere in this Fund’s prospectus. Purchasers will have to buy mutual fund shares directly from the mutual fund company or through another intermediary to be eligible for waivers or discounts not listed below.

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 (the referenced Merrill documents and Web site do not form a part of this prospectus). Clients are encouraged to review these documents and speak with their financial advisor to determine whether a transaction is eligible for a waiver or discount.

EDWARD D. JONES & CO., L.P. (“EDWARD JONES”)

POLICIES REGARDING TRANSACTIONS THROUGH EDWARD JONES

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 DWS Funds, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation 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 DWS Funds 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).

Prospectus May 1, 2025

Appendix B

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.

Front-end Sales Charge Waivers on Class A Shares Available at Edward Jones

Class A front-end 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.

The redemption and repurchase occur in the same account.

The redemption proceeds are used to process an: IRA contribution, excess contributions, conversion, recharacterizing of contributions, or distribution, and the repurchase is done in an account within the same Edward Jones grouping for ROA.

The Right of Reinstatement excludes systematic or automatic transaction including, but not limited to purchases made through payroll deductions, liquidations to cover account fees, and reinvestments from non-mutual fund products.

■

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 by and at the discretion of Edward Jones.
