You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The Fund may impose a fee upon sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time. You should not rely on or expect the Advisor to enter into support agreements or take other actions to maintain the Fund’s $1.00 share price. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. The actions of a few large investors in one class of shares of the Fund may have a significant adverse effect on the share prices of all classes of shares of the Fund.

Letter to Shareholders

Dear Shareholder:

The picture for the economy and markets continues to be positive with corporate fundamentals continuing to be solid, a tight labor market and inflation near the Federal Reserve Bank’s target.

Nevertheless, the fourth quarter of 2018 introduced a level of volatility that investors have not seen in quite a while. That trend continues into the new year, triggered by uncertainty around trade conflicts, the withdrawal of liquidity by central banks, higher interest rates and concerns around European hot spots such as Italy and the United Kingdom.

While these issues bear close watching, our Chief investment Officer (“CIO”) and Chief Economist agree that the markets remain broadly attractive. The rate hike cycle appears to be nearing its end, inflation remains under control and recession is not on the near horizon.

The “Insight” section of our Web site, dws.com, is home to a comprehensive library of market and economic views around current developments, opportunities and emerging risks. We invite you to visit us online often to stay apprised of the market landscape and what it may mean for you.

Best regards,

Hepsen Uzcan   President, DWS Funds

Fair Value Measurements

Various inputs are used in determining the value of the Fund’s investments. These inputs are summarized in three broad levels. Level 1 includes quoted prices in active markets for identical securities. Level 2 includes other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds and credit risk). Level 3 includes significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments). The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities. Securities held by the Fund are reflected as Level 2 because the securities are valued at amortized cost (which approximates fair value) and, accordingly, the inputs used to determine value are not quoted prices in an active market.

The following is a summary of the inputs used as of January 31, 2019 in valuing the Fund’s investments. For information on the Fund’s policy regarding the valuation of investments, please refer to the Security Valuation section of Note A in the accompanying Notes to Financial Statements.

Notes to Financial Statements (Unaudited)

A. Organization and Significant Accounting Policies

DWS Money Market Prime Series (the “Fund”) is a diversified series of Deutsche DWS Money Funds (the “Trust”), which is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company organized as a Massachusetts business trust. The Fund seeks to qualify as a retail money market fund and may impose liquidity fees on redemptions and/or temporarily suspend (gate) redemptions if the Fund’s liquidity falls below required minimums because of market conditions or other factors.

The Fund offers multiple classes of shares which provide investors with different purchase options: DWS Cash Investment Trust Class A shares are not subject to an initial sales charge but are subject to the applicable sales charge if exchanged into Class A shares of another DWS Fund. DWS Cash Investment Trust Class C shares are not subject to an initial sales charge but are subject to higher ongoing expenses than DWS Cash Investment Trust Class A shares and a contingent deferred sales charge payable upon certain redemptions within one year of purchase. Effective on August 10, 2018, Class C shares automatically convert to Class A shares in the same fund after 10 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 10 years. DWS Money Market Fund and DWS Cash Investment Trust Class S shares are not subject to initial or contingent deferred sales charges. DWS Cash Investment Trust Class S shares are only available to a limited group of investors.

Investment income, realized gains and losses, and certain fund-level expenses and expense reductions, if any, are borne pro rata on the basis of relative net assets by the holders of all classes of shares, except that each class bears certain expenses unique to that class such as distribution and service fees, services to shareholders and certain other class-specific expenses. Differences in class-level expenses may result in payment of different per share dividends by class. All shares of the Fund have equal rights with respect to voting subject to class-specific arrangements.

The Fund’s financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) which require the use of management estimates. Actual results could differ from those estimates. The Fund qualifies as an investment company under Topic 946 of Accounting Standards Codification of U.S. GAAP. The policies described below are followed consistently by the Fund in the preparation of their financial statements.

DWS Money Market Prime Series | 17

In October 2018, the Securities and Exchange Commission adopted amendments to certain disclosure requirements in Securities Act Release No. 33-10532, Disclosure Update and Simplification, which is intended to facilitate the disclosure of information to investors and simplify compliance without significantly altering the total mix of information provided to investors. Effective with the current reporting period, the Fund adopted the amendments with the impacts being that the Fund is no longer required to present components of distributable earnings on the Statement of Assets and Liabilities or the sources of distributable earnings and the amount of undistributed net investment income on the Statements of Changes in Net Assets.

Security Valuation. Various inputs are used in determining the value of the Fund’s investments. These inputs are summarized in three broad levels. Level 1 includes quoted prices in active markets for identical securities. Level 2 includes other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds and credit risk). Level 3 includes significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments). The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities.

The Fund values all securities utilizing the amortized cost method permitted in accordance with Rule 2a-7 under the 1940 Act and certain conditions therein. Under this method, which does not take into account unrealized capital gains or losses on securities, an instrument is initially valued at its cost and thereafter assumes a constant accretion/ amortization rate to maturity of any discount or premium. Securities held by the Fund are reflected as Level 2 because the securities are valued at amortized cost (which approximates fair value) and, accordingly, the inputs used to determine value are not quoted prices in an active market.

Disclosure about the classification of fair value measurements is included in a table following the Fund’s Investment Portfolio.

Repurchase Agreements. The Fund may enter into repurchase agreements, under the terms of a Master Repurchase Agreement, with certain banks and broker/dealers whereby the Fund, through its custodian or a sub-custodian bank, receives delivery of the underlying securities, the amount of which at the time of purchase and each subsequent business day is required to be maintained at such a level that the market value is equal to at least the principal amount of the repurchase price plus accrued interest. The custodian or another designated sub-custodian bank holds the collateral in a separate account until the agreement matures. If the value of the securities falls below the principal amount of the repurchase agreement plus accrued interest, the financial institution deposits additional collateral by the following business day. If the financial

18 | DWS Money Market Prime Series

institution either fails to deposit the required additional collateral or fails to repurchase the securities as agreed, the Fund has the right to sell the securities and recover any resulting loss from the financial institution. If the financial institution enters into bankruptcy, the Fund’s claims on the collateral may be subject to legal proceedings.

As of January 31, 2019, the Fund held repurchase agreements with a gross value of $106,600,000. The value of the related collateral exceeded the value of the repurchase agreements at period end. The detail of the related collateral is included in the footnotes following the Fund’s Investment Portfolio.

Federal Income Taxes. The Fund’s policy is to comply with the requirements of the Internal Revenue Code, as amended, which are applicable to regulated investment companies, and to distribute all of its taxable income to its shareholders.

At July 31, 2018, the Fund had a net tax basis capital loss carryforward of approximately $1,000, which may be applied against any realized net taxable capital gains of each succeeding year until fully utilized.

At January 31, 2019, the aggregated cost of investments for federal income tax purposes was $725,538,892.

The Fund has reviewed the tax positions for the open tax years as of July 31, 2018 and has determined that no provision for income tax and/or uncertain tax positions is required in the Fund’s financial statements. The Fund’s federal tax returns for the prior three fiscal years remain open subject to examination by the Internal Revenue Service.

Distribution of Income and Gains. Net investment income of the Fund is declared as a daily dividend and is distributed to shareholders monthly. The Fund may take into account capital gains and losses in its daily dividend declarations. The Fund may also make additional distributions for tax purposes if necessary.

Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications to paid in capital. Temporary book and tax basis differences will reverse in a subsequent period. There were no significant book-to-tax differences for the Fund.

The tax character of current year distributions will be determined at the end of the current fiscal year.

Contingencies. In the normal course of business, the Fund may enter into contracts with service providers that contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet been made. However, based on experience, the Fund expects the risk of loss to be remote.

DWS Money Market Prime Series | 19

Other. Investment transactions are accounted for on trade date. Interest income is recorded on the accrual basis. Realized gains and losses from investment transactions are recorded on an identified cost basis. All discounts and premiums are accreted/amortized for both tax and financial reporting purposes.

B. Related Parties

Management Agreement. Under the Investment Management Agreement with DWS Investment Management Americas, Inc. (“DIMA” or the “Advisor”), an indirect, wholly owned subsidiary of DWS Group GmbH & Co. KGaA (“DWS Group”), the Advisor directs the investments of the Fund in accordance with their investment objectives, policies and restrictions. The Advisor determines the securities, instruments and other contracts relating to investments to be purchased, sold or entered into by the Fund.

Under the Investment Management Agreement with the Advisor, the Fund pays a monthly management fee based on the Fund’s average daily net assets, computed and accrued daily and payable monthly, at the following annual rates:

First $215 million of the Fund’s average daily net assets	.400%
Next $335 million of such net assets	.275%
Next $250 million of such net assets	.200%
Next $800 million of such net assets	.150%
Next $800 million of such net assets	.140%
Next $800 million of such net assets	.130%
Over $3.2 billion of such net assets	.120%

Accordingly, for the six months ended January 31, 2019, the fee pursuant to the Investment Management Agreement was equivalent to an annualized rate (exclusive of any applicable waivers/reimbursements) of 0.29% of the Fund’s average daily net assets.

For the period from August 1, 2018 through September 30, 2019, the Advisor has contractually agreed to waive its fees and/or reimburse certain operating expenses of the Fund to the extent necessary to maintain the total annual operating expenses (excluding certain expenses such as extraordinary expenses, taxes, brokerage and interest) of each class as follows:

DWS Cash Investment Trust Class A	.85%
DWS Cash Investment Trust Class C	1.60%
DWS Cash Investment Trust Class S	.57%

Trustees’ Fees and Expenses. The Fund paid retainer fees to each Trustee not affiliated with the Advisor, plus specified amounts to the Board Chairperson and to each committee Chairperson.

Transactions with Affiliates. The Fund may purchase securities from, or sell securities to, an affiliated fund provided the affiliation is solely due to having a common investment adviser, common officers, or common trustees.

The Fund and other affiliated funds (the “Participants”) share in a $400 million revolving credit facility provided by a syndication of banks. The Fund may borrow for temporary or emergency purposes, including the meeting of redemption requests that otherwise might require the untimely disposition of securities. The Participants are charged an annual commitment fee which is allocated based on net assets, among each of the Participants. Interest is calculated at a rate per annum equal to the sum of the Federal Funds Rate plus 1.25 percent plus if the one-month LIBOR exceeds the Federal Funds Rate, the amount of such excess. The Fund may borrow up to a maximum of 33 percent of its net assets under the agreement. The Fund had no outstanding loans at January 31, 2019.

Information About Your Fund’s Expenses

As an investor, you incur two types of costs: ongoing expenses and transaction costs. Ongoing expenses include management fees, distribution and service (12b-1) fees and other Fund expenses. Examples of transaction costs include account maintenance fees, which are not shown in this section. The following tables are intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to help you compare these expenses with the ongoing expenses of investing in other mutual funds. In the most recent six-month period, the Fund limited these expenses for DWS Cash Investment Trust Class S shares and DWS Money Market Fund shares; had it not done so, expenses would have been higher. The example in the table is based on an investment of $1,000 invested at the beginning of the six-month period and held for the entire period (August 1, 2018 to January 31, 2019).

The tables illustrate your Fund’s expenses in two ways:

– Actual Fund Return. This helps you estimate the actual dollar amount of ongoing expenses (but not transaction costs) paid on a $1,000 investment in the Fund using the Fund’s actual return during the period. To estimate the expenses you paid over the period, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Expenses Paid per $1,000” line under the share class you hold.

– Hypothetical 5% Fund Return. This helps you to compare your Fund’s ongoing expenses (but not transaction costs) with those of other mutual funds using the Fund’s actual expense ratio and a hypothetical rate of return of 5% per year before expenses. Examples using a 5% hypothetical fund return may be found in the shareholder reports of other mutual funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

Please note that the expenses shown in these tables are meant to highlight your ongoing expenses only and do not reflect any transaction costs. The “Expenses Paid per $1,000” line of the tables is useful in comparing ongoing expenses only and will not help you determine the relative total expense of owning different funds. Subject to certain exceptions, an account maintenance fee of $20.00 assessed once per calendar year for DWS Cash Investment Trust Class A, DWS Cash Investment Trust Class C and DWS Cash Investment Trust Class S shares may apply for accounts with balances less than $10,000. This fee is not included in these tables. If it was, the estimate of expenses paid for these shares during the period would be higher, and account value during the period would be lower, by this amount.

Advisory Agreement Board Considerations and Fee Evaluation

The Board of Trustees (hereinafter referred to as the “Board” or “Trustees”) approved the renewal of DWS Money Market Prime Series’ (the “Fund”) investment management agreement (the “Agreement”) with DWS Investment Management Americas, Inc. (“DIMA”) in September 2018.

In terms of the process that the Board followed prior to approving the Agreement, shareholders should know that:

– During the entire process, all of the Fund’s Trustees were independent of DIMA and its affiliates (the “Independent Trustees”).

– The Board met frequently during the past year to discuss fund matters and dedicated a substantial amount of time to contract review matters. Over the course of several months, the Board’s Contract Committee reviewed extensive materials received from DIMA, independent third parties and independent counsel. These materials included an analysis of the Fund’s performance, fees and expenses, and profitability from a fee consultant retained by the Fund’s Independent Trustees (the “Fee Consultant”). Based on its evaluation of the information provided, the Contract Committee presented its findings and recommendations to the Board. The Board then reviewed the Contract Committee’s findings and recommendations.

– The Board also received extensive information throughout the year regarding performance of the Fund.

– The Independent Trustees regularly met privately with counsel to discuss contract review and other matters. In addition, the Independent Trustees were advised by the Fee Consultant in the course of their review of the Fund’s contractual arrangements and considered a comprehensive report prepared by the Fee Consultant in connection with their deliberations.

– In connection with reviewing the Agreement, the Board also reviewed the terms of the Fund’s Rule 12b-1 plan, distribution agreement, administrative services agreement, transfer agency agreement and other material service agreements.

In connection with the contract review process, the Contract Committee and the Board considered the factors discussed below, among others. The Board also considered that DIMA and its predecessors have managed the Fund since its inception, and the Board believes that a long-term relationship with a capable, conscientious advisor is in the best interests of the Fund. The Board considered, generally, that shareholders chose to invest or remain invested in the Fund knowing that DIMA managed the

DWS Money Market Prime Series | 27

Fund. DIMA is part of DWS Group GmbH & Co. KGaA (“DWS Group”). DWS Group is a global asset management business that offers a wide range of investing expertise and resources, including research capabilities in many countries throughout the world. In 2018, approximately 20% of DWS Group’s shares were sold in an initial public offering, with Deutsche Bank AG owning the remaining shares.

As part of the contract review process, the Board carefully considered the fees and expenses of each DWS fund overseen by the Board in light of the fund’s performance. In many cases, this led to the negotiation and implementation of expense caps. As part of these negotiations, the Board indicated that it would consider relaxing these caps in future years following sustained improvements in performance, among other considerations.

While shareholders may focus primarily on fund performance and fees, the Fund’s Board considers these and many other factors, including the quality and integrity of DIMA’s personnel and administrative support services provided by DIMA, such as back-office operations, fund valuations, and compliance policies and procedures.

Nature, Quality and Extent of Services. The Board considered the terms of the Agreement, including the scope of advisory services provided under the Agreement. The Board noted that, under the Agreement, DIMA provides portfolio management services to the Fund and that, pursuant to a separate administrative services agreement, DIMA provides administrative services to the Fund. The Board considered the experience and skills of senior management and investment personnel and the resources made available to such personnel. The Board reviewed the Fund’s performance over short-term and long-term periods and compared those returns to various agreed-upon performance measures, including a peer universe compiled using information supplied by iMoneyNet, an independent fund data service. The Board also noted that it has put into place a process of identifying “Funds in Review” (e.g., funds performing poorly relative to a peer universe), and receives additional reporting from DIMA regarding such funds and, where appropriate, DIMA’s plans to address underperformance. The Board believes this process is an effective manner of identifying and addressing underperforming funds. Based on the information provided, the Board noted that, for the one- and three-year periods ended December 31, 2017, the Fund’s gross performance (DWS Cash Investment Trust Class A shares) was in the 3rd quartile and 2nd quartile, respectively, of the applicable iMoneyNet universe (the 1st quartile being the best performers and the 4th quartile being the worst performers).

Fees and Expenses. The Board considered the Fund’s investment management fee schedule, operating expenses and total expense ratios, and comparative information provided by Broadridge Financial Solutions, Inc. (“Broadridge”) and the Fee Consultant regarding investment

28 | DWS Money Market Prime Series

management fee rates paid to other investment advisors by similar funds (1st quartile being the most favorable and 4th quartile being the least favorable). With respect to management fees paid to other investment advisors by similar funds, the Board noted that the contractual fee rates paid by the Fund, which include a 0.10% fee paid to DIMA under the Fund’s administrative services agreement, were higher than the median (3rd quartile) of the applicable Broadridge peer group (based on Broadridge data provided as of December 31, 2017). Based on Broadridge data provided as of December 31, 2017, the Board noted that the Fund’s total operating expenses (excluding 12b-1 fees and/or shareholder administration fees, if applicable) were higher than the median of the applicable Broadridge expense universe (less any applicable 12b-1 fees) for the following share classes: DWS Cash Investment Trust Class A shares (4th quartile), DWS Cash Investment Trust Class S shares (4th quartile), DWS Money Market Fund shares (4th quartile) and DWS Cash Investment Trust Class C shares (4th quartile). The Board noted the expense limitations agreed to by DIMA. The Board also noted the voluntary fee waivers implemented by DIMA prior to December 31, 2017 to ensure the Fund maintained a positive yield. The Board considered the Fund’s management fee rate as compared to fees charged by DIMA to comparable DWS U.S. registered funds (“DWS Funds”) and considered differences between the Fund and the comparable DWS Funds. The information requested by the Board as part of its review of fees and expenses also included information about institutional accounts (including any sub-advised funds and accounts) and funds offered primarily to European investors (“DWS Europe Funds”) managed by DWS Group. The Board noted that DIMA indicated that DWS Group does not manage any institutional accounts or DWS Europe Funds comparable to the Fund.

On the basis of the information provided, the Board concluded that management fees were reasonable and appropriate in light of the nature, quality and extent of services provided by DIMA.

Profitability. The Board reviewed detailed information regarding revenues received by DIMA under the Agreement. The Board considered the estimated costs to DIMA, and pre-tax profits realized by DIMA, from advising the DWS Funds, as well as estimates of the pre-tax profits attributable to managing the Fund in particular. The Board also received information regarding the estimated enterprise-wide profitability of DIMA and its affiliates with respect to all fund services in totality and by fund. The Board and the Fee Consultant reviewed DIMA’s methodology in allocating its costs to the management of the Fund. Based on the information provided, the Board concluded that the pre-tax profits realized by DIMA in connection with the management of the Fund were not unreasonable. The Board also reviewed certain publicly available information regarding the profitability of certain similar investment management firms. The Board noted that, while information regarding the

DWS Money Market Prime Series | 29

profitability of such firms is limited (and in some cases is not necessarily prepared on a comparable basis), DIMA and its affiliates’ overall profitability with respect to the DWS Funds (after taking into account distribution and other services provided to the funds by DIMA and its affiliates) was lower than the overall profitability levels of most comparable firms for which such data was available.

Economies of Scale. The Board considered whether there are economies of scale with respect to the management of the Fund and whether the Fund benefits from any economies of scale. The Board noted that the Fund’s investment management fee schedule includes fee breakpoints. The Board concluded that the Fund’s fee schedule represents an appropriate sharing between the Fund and DIMA of such economies of scale as may exist in the management of the Fund at current asset levels.

Other Benefits to DIMA and Its Affiliates. The Board also considered the character and amount of other incidental or “fall-out” benefits received by DIMA and its affiliates, including any fees received by DIMA for administrative services provided to the Fund, any fees received by an affiliate of DIMA for transfer agency services provided to the Fund and any fees received by an affiliate of DIMA for distribution services. The Board also considered benefits to DIMA related to brokerage and soft-dollar allocations, including allocating brokerage to pay for research generated by parties other than the executing broker dealers, which pertain primarily to funds investing in equity securities. In addition, the Board considered the incidental public relations benefits to DIMA related to DWS Funds advertising and cross-selling opportunities among DIMA products and services. The Board considered these benefits in reaching its conclusion that the Fund’s management fees were reasonable.

Compliance. The Board considered the significant attention and resources dedicated by DIMA to its compliance processes in recent years. The Board noted in particular (i) the experience, seniority and time commitment of the individuals serving as DIMA’s and the Fund’s chief compliance officers and (ii) the substantial commitment of resources by DIMA and its affiliates to compliance matters, including the retention of compliance personnel.

Based on all of the information considered and the conclusions reached, the Board unanimously determined that the continuation of the Agreement is in the best interests of the Fund. In making this determination, the Board did not give particular weight to any single factor identified above. The Board considered these factors over the course of numerous meetings, certain of which were in executive session with only the Independent Trustees and counsel present. It is possible that individual Independent Trustees may have weighed these factors differently in reaching their individual decisions to approve the continuation of the Agreement.
