 Fund

Beginning on January 1, 2021, as permitted by regulations adopted by the Securities and Exchange Commission, paper copies of the Fund’s annual and semiannual shareholder reports will no longer be sent by mail, unless you specifically request paper copies of the reports. Instead, the reports will be made available on the Fund’s Web site (dws.com), and you will be notified by mail each time a report is posted and provided with a Web site link to access the report.

If you already elected to receive shareholder reports electronically, you will not be affected by this change and you need not take any action. You may elect to receive shareholder reports and other communications from the Fund electronically anytime by contacting your financial intermediary (such as a broker-dealer or bank), or if you are a direct investor, by calling (800) 728-3337 or sending an email request to service@dws.com.

You may elect to receive all future reports in paper free of charge. If you invest through a financial intermediary, you can contact your financial intermediary to request that you continue to receive paper copies of your shareholder reports. If you invest directly with the Fund, you can call (800) 728-3337 or send an email request to service@dws.com to continue receiving paper copies of your shareholder reports. Your election to receive reports in paper will apply to all funds held in your account if you invest through your financial intermediary or all funds held with DWS if you invest directly with the Fund.

Any fund that concentrates in a particular segment of the market will generally be more volatile than a fund that invests more broadly. Investing in derivatives entails special risks relating to liquidity, leverage and credit that may reduce returns and/or increase volatility. This Fund is non-diversified and can take larger positions in fewer issues, increasing its potential risk. The Fund may lend securities to approved institutions. Stocks may decline in value. Please read the prospectus for details.

Letter to Shareholders

Dear Shareholder:

Despite shifting political sands — most notably the trade negotiations between China and the United States (the “U.S.”) — the economy continues to be resilient. A robust labor market, strong home sales, consumer confidence and other key metrics indicate that the underpinnings of the economy remain intact.

Looking ahead, while our Americas Chief Investment Officer (“CIO”) believes the U.S.-China trade conflict may de-escalate over the coming months, he notes that it is most likely to weigh on manufacturing activity. Since certain aspects of the conflict, such as intellectual property protection and other China reforms, will not happen quickly, the conflict could prolong into the second half of the year. In any event, uncertainty may well lead to continued market volatility. Against this backdrop, we see little near-term impetus for a resurgence in growth in the emerging markets beyond the stimulus efforts that are already underway in China.

Of course, these issues and their potential implications around the world bear close watching. Our CIO Office and global network of analysts diligently monitor these matters to determine when and what, if any, strategic or tactical adjustments are warranted. We invite you to access these views often to understand the changing landscape and, most important, what it may mean for you.

While our diverse expertise in Active, Passive and Alternatives asset management — as well as our deep environmental, social and governance focus — complement each other when creating targeted investment strategies for our clients, the on-the-ground-knowledge of our economists, research analysts and investment professionals are brought together in one consistent global CIO View, which guides our strategic investment approach. We are local while being one global team with approximately 3,600 employees in offices all over the world. As always, we urge you to visit the “Insights” section of our Web site, dws.com, to review our most current market and economic perspectives.

Best regards,

Hepsen Uzcan   President, DWS Funds

Performance in the Average Annual Total Returns table(s) above and the Growth of an Assumed $10,000 Investment line graph that follows is historical and does not guarantee future results. Investment return and principal fluctuate, so your shares may be worth more or less when redeemed. Current performance may differ from performance data shown. Please visit dws.com for the Fund’s most recent month-end performance. Fund performance includes reinvestment of all distributions. Unadjusted returns do not reflect sales charges and would have been lower if they had.

The gross expense ratios of the Fund, as stated in the fee table of the prospectus dated March 1, 2019 are 0.93%, 1.78%, 0.77% and 0.72% for Class A, Class C, Class S and Institutional Class shares, respectively, and may differ from the expense ratios disclosed in the Financial Highlights tables in this report.

Index returns do not reflect any fees or expenses and it is not possible to invest directly into an index.

Performance figures do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares.

Generally accepted accounting principles require adjustments to be made to the net assets of the Fund at period end for financial reporting purposes only, and as such, the total return based on the unadjusted net asset value per share may differ from the total return reported in the financial highlights.

* Non-income producing security.

(a) All or a portion of these securities were on loan. In addition, “Other Assets and Liabilities, Net” may include pending sales that are also on loan. The value of securities loaned at April 30, 2019 amounted to $10,318,580, which is 1.2% of net assets.

(b) Investment was valued using significant unobservable inputs.

(c) The Fund may purchase securities that are subject to legal or contractual restrictions on resale (“restricted securities”). Restricted securities are securities which have not been registered with the Securities and Exchange Commission under the Securities Act of 1933. The Fund may be unable to sell a restricted security and it may be more difficult to determine a market value for a restricted security. Moreover, if adverse market conditions were to develop during the period between the Fund’s decision to sell a restricted security and the point at which the Fund is permitted or able to sell such security, the Fund might obtain a price less favorable than the price that prevailed when it decided to sell. This investment practice, therefore, could have the effect of increasing the level of illiquidity of the Fund. The future value of these securities is uncertain and there may be changes in the estimated value of these securities.

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. The Fund has adopted ASU No. 2015-07, Disclosures for Investments in Certain Entities that calculate Net Asset Value Per Share (NAV). The fair value hierarchy now excludes certain investments which are valued using NAV as a practical expedient.

The following is a summary of the inputs used as of April 30, 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 Science and Technology Fund (the “Fund”) is a non-diversified series of Deutsche DWS Securities Trust (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 offers multiple classes of shares which provide investors with different purchase options. Class A shares are subject to an initial sales charge. Class C shares are not subject to an initial sales charge but are subject to higher ongoing expenses than Class A shares and a contingent deferred sales charge payable upon certain redemptions within one year of purchase. 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. Class S shares are not subject to initial or contingent deferred sales charges and are only available to a limited group of investors. Institutional Class shares are not subject to initial or contingent deferred sales charges and are generally available only to qualified institutions.

Investment income, realized and unrealized 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 its financial statements.

Security Valuation. Investments are stated at value determined as of the close of regular trading on the New York Stock Exchange on each day the exchange is open for trading.

DWS Science and Technology Fund | 23

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.

Equity securities are valued at the most recent sale price or official closing price reported on the exchange (U.S. or foreign) or over-the-counter market on which they trade. Securities for which no sales are reported are valued at the calculated mean between the most recent bid and asked quotations on the relevant market or, if a mean cannot be determined, at the most recent bid quotation. Equity securities are generally categorized as Level 1. For certain international equity securities, in order to adjust for events which may occur between the close of the foreign exchanges and the close of the New York Stock Exchange, a fair valuation model may be used. This fair valuation model takes into account comparisons to the valuation of American Depository Receipts (ADRs), exchange-traded funds, futures contracts and certain indices and these securities are categorized as Level 2.

Investments in open-end investment companies are valued at their net asset value each business day and are categorized as Level 1.

The other investments represent investments in venture capital funds which are valued at their net asset value as a practical expedient. The net asset value of venture capital funds has been estimated primarily based upon the pro-rata ownership of the fair value of the venture capital funds as reported by the Management of the venture capital funds. Investments in venture capital funds can never be redeemed with the venture capital funds. Instead, the nature of the investments in this category is that distributions are received through the liquidation of the underlying assets of the venture capital funds.

Securities and other assets for which market quotations are not readily available or for which the above valuation procedures are deemed not to reflect fair value are valued in a manner that is intended to reflect their fair value as determined in accordance with procedures approved by the Board and are generally categorized as Level 3. In accordance with the Fund’s valuation procedures, factors considered in determining value may include, but are not limited to, the type of the security; the size of the holding; the initial cost of the security; the existence of any contractual restrictions on the security’s disposition; the price and extent of public trading in similar securities of the issuer or of comparable companies;

24 | DWS Science and Technology Fund

quotations or evaluated prices from broker-dealers and/or pricing services; information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities); an analysis of the company’s or issuer’s financial statements; an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold; and with respect to debt securities, the maturity, coupon, creditworthiness, currency denomination and the movement of the market in which the security is normally traded. The value determined under these procedures may differ from published values for the same securities.

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

Foreign Currency Translations. The books and records of the Fund are maintained in U.S. dollars. Investment securities and other assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the prevailing exchange rates at period end. Purchases and sales of investment securities, income and expenses are translated into U.S. dollars at the prevailing exchange rates on the respective dates of the transactions.

Net realized and unrealized gains and losses on foreign currency transactions represent net gains and losses between trade and settlement dates on securities transactions, the acquisition and disposition of foreign currencies, and the difference between the amount of net investment income accrued and the U.S. dollar amount actually received. The portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed but is included with net realized and unrealized gain/appreciation and loss/depreciation on investments.

Securities Lending. Deutsche Bank AG, as lending agent, lends securities of the Fund to certain financial institutions under the terms of its securities lending agreement. During the term of the loans, the Fund continues to receive interest and dividends generated by the securities and to participate in any changes in their market value. The Fund requires the borrowers of the securities to maintain collateral with the Fund consisting of either cash or liquid, unencumbered assets having a value at least equal to the value of the securities loaned. When the collateral falls below specified amounts, the lending agent will use its best effort to obtain additional collateral on the next business day to meet required amounts under the securities lending agreement. As of period end, any securities on loan were collateralized by cash. During six months ended April 30, 2019, the Fund invested the cash collateral into a joint trading account in DWS Government & Agency Securities Portfolio, an affiliated money market fund managed by DWS Investment Management

DWS Science and Technology Fund | 25

Americas, Inc. DWS Investment Management Americas, Inc. receives a management/administration fee (0.12% annualized effective rate as of April 30, 2019) on the cash collateral invested in DWS Government & Agency Securities Portfolio. The Fund receives compensation for lending its securities either in the form of fees or by earning interest on invested cash collateral net of borrower rebates and fees paid to a lending agent. Either the Fund or the borrower may terminate the loan at any time, and the borrower, after notice, is required to return borrowed securities within a standard time period. There may be risks of delay and costs in recovery of securities or even loss of rights in the collateral should the borrower of the securities fail financially. If the Fund is not able to recover securities lent, the Fund may sell the collateral and purchase a replacement investment in the market, incurring the risk that the value of the replacement security is greater than the value of the collateral. The Fund is also subject to all investment risks associated with the reinvestment of any cash collateral received, including, but not limited to, interest rate, credit and liquidity risk associated with such investments.

As of April 30, 2019, the Fund had securities on loan, which were classified as common stocks in the Investment Portfolio. The value of the related collateral exceeded the value of the securities loaned at period end. As of period end, the remaining contractual maturity of the collateral agreements was overnight and continuous.

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.

Additionally, the Fund may be subject to taxes imposed by the governments of countries in which it invests and are generally based on income and/or capital gains earned or repatriated. Estimated tax liabilities on certain foreign securities are recorded on an accrual basis and are reflected as components of interest income or net change in unrealized gain/loss on investments. Tax liabilities realized as a result of security sales are reflected as a component of net realized gain/loss on investments.

At April 30, 2019, the aggregate cost of investments for federal income tax purposes was $518,938,287. The net unrealized appreciation for all investments based on tax cost was $388,937,691. This consisted of aggregate gross unrealized appreciation for all investments which there was an excess of value over tax cost of $415,766,823 aggregate gross unrealized depreciation for all investments in which was an excess of tax cost over value of $26,829,132.

The Fund has reviewed the tax positions for the open tax years as of October 31, 2018 and has determined that no provision for income tax and/or uncertain tax positions is required in the Fund’s financial

26 | DWS Science and Technology Fund

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. Distributions from net investment income of the Fund, if any, are declared and distributed to shareholders annually. Net realized gains from investment transactions, in excess of available capital loss carryforwards, would be taxable to the Fund if not distributed, and, therefore, will be distributed to shareholders at least annually. The Fund may also make additional distributions for tax purposes, if necessary.

The timing and characterization of certain income and capital gain distributions are determined annually in accordance with federal tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences primarily relate to certain securities sold at a loss and investments in limited partnerships. As a result, net investment income (loss) and net realized gain (loss) on investment transactions for a reporting period may differ significantly from distributions during such period. Accordingly, the Fund may periodically make reclassifications among certain of its capital accounts without impacting the net asset value of the Fund.

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

Expenses. Expenses of the Trust arising in connection with a specific fund are allocated to that fund. Other Trust expenses which cannot be directly attributed to a fund are apportioned among the funds in the Trust based upon the relative net assets or other appropriate measures.

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.

Other. Investment transactions are accounted for on a trade date plus one basis for daily net asset value calculations. However, for financial reporting purposes, investment transactions are reported on trade date. Interest income is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date net of foreign withholding taxes. Certain dividends from foreign securities may be recorded subsequent to the ex-dividend date as soon as the Fund is informed of such dividends. Realized gains and losses from investment transactions are recorded on an identified cost basis. Proceeds from litigation payments, if any, are included in net realized gain (loss) from investments.

B. Purchases and Sales of Securities

During the six months ended April 30, 2019, purchases and sales of investment securities (excluding short-term instruments) aggregated $263,827,591 and $275,866,070, respectively.

C. 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 its 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 or delegates such responsibility to the Fund’s subadvisor.

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 1/12 of the following annual rates:

First $250 million of the Fund’s average daily net assets	.48%
Next $750 million of such net assets	.45%
Next $1.5 billion of such net assets	.43%
Next $2.5 billion of such net assets	.41%
Next $2.5 billion of such net assets	.38%
Next $2.5 billion of such net assets	.36%
Next $2.5 billion of such net assets	.34%
Over $12.5 billion of such net assets	.32%

Accordingly, for the six months ended April 30, 2019, the fee pursuant to the Investment Management Agreement was equivalent to an annualized rate (exclusive of any applicable waivers/reimbursements) of 0.46% of the Fund’s average daily net assets.

For the period from November 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:

Class A	1.30%
Class C	2.05%
Class S	1.05%
Institutional Class	1.05%

28 | DWS Science and Technology Fund

Administration Fee. Pursuant to an Administrative Services Agreement, DIMA provides most administrative services to the Fund. For all services provided under the Administrative Services Agreement, the Fund pays the Advisor an annual fee (“Administration Fee”) of 0.10% of the Fund’s average daily net assets, computed and accrued daily and payable monthly. For the six months ended April 30, 2019, the Administration Fee was $396,942, of which $71,987 is unpaid.

Service Provider Fees. DWS Service Company (“DSC”), an affiliate of the Advisor, is the Fund’s transfer agent, dividend-paying agent and shareholder service agent for the Fund. Pursuant to a sub-transfer agency agreement between DSC and DST Systems, Inc. (“DST”), DSC has delegated certain transfer agent, dividend-paying agent and shareholder service agent functions to DST. DSC compensates DST out of the shareholder servicing fee it receives from the Fund. For the six months ended April 30, 2019, the amounts charged to the Fund by DSC were as follows:

Services to Shareholders	Total Aggregated		Unpaid at April 30, 2019
Class A	$	132,852	$	42,773
Class C		5,139		4,970
Class S		62,442		21,309
Institutional Class		414		41
	$	200,847	$	69,093

In addition, for the six months ended April 30, 2019, the amounts charged to the Fund for recordkeeping and other administrative services provided by unaffiliated third parties, included in the Statement of Operations under “Services to shareholders,” were as follows:

Sub-Recordkeeping	Total Aggregated
Class A	$	194,823
Class C		7,839
Class S		36,936

DWS Science and Technology Fund | 29

with various firms at various rates for sales of Class C shares. For the six months ended April 30, 2019, the Distribution Fee was as follows:

Distribution Fee	Total Aggregated		Unpaid at April 30, 2019
Class C	$	47,006	$	8,370

In addition, DDI provides information and administrative services for a fee (“Service Fee”) to Class A and C shareholders at an annual rate of up to 0.25% of average daily net assets for each such class. DDI in turn has various agreements with financial services firms that provide these services and pays these fees based upon the assets of shareholder accounts the firms service. For the six months ended April 30, 2019, the Service Fee was as follows:

Service Fee	Total Aggregated		Unpaid at April 30, 2019		Annualized Rate
Class A	$	690,729	$	248,792		.22	%

In addition, DDI receives any contingent deferred sales charge (“CDSC”) from Class C share redemptions occurring within one year of purchase. There is no such charge upon redemption of any share appreciation or reinvested dividends. The CDSC is 1% of the value of shares redeemed for Class C. For the six months ended April 30, 2019, the CDSC for Class C shares aggregated $439. A deferred sales charge of up to 1% is assessed on certain redemptions of Class A shares.

Typesetting and Filing Service Fees. Under an agreement with the Fund, DIMA is compensated for providing certain pre-press and regulatory filing services to the Fund. For the six months ended April 30, 2019, the amount charged to the Fund by DIMA included in the Statement of Operations under “Reports to shareholders” aggregated $9,022, all of which is unpaid.

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.

Affiliated Cash Management Vehicles. The Fund may invest uninvested cash balances in DWS Central Cash Management Government Fund and DWS ESG Liquidity Fund, affiliated money market funds which are

30 | DWS Science and Technology Fund

managed by the Advisor. Each affiliated money market fund is managed in accordance with Rule 2a-7 under the 1940 Act, which governs the quality, maturity, diversity and liquidity of instruments in which a money market fund may invest. DWS Central Cash Management Government Fund seeks to maintain a stable net asset value, and DWS ESG Liquidity Fund maintains a floating net asset value. The Fund indirectly bears its proportionate share of the expenses of each affiliated money market fund in which it invests. DWS Central Cash Management Government Fund does not pay the Advisor an investment management fee. To the extent that DWS ESG Liquidity Fund pays an investment management fee to the Advisor, the Advisor will waive an amount of the investment management fee payable to the Advisor by the Fund equal to the amount of the investment management fee payable on the Fund’s assets invested in DWS ESG Liquidity Fund.

Security Lending Fees. Deutsche Bank AG serves as securities lending agent for the Fund. For the six months ended April 30, 2019, the Fund incurred lending agent fees to Deutsche Bank AG for the amount of $1,309.

D. Investing in Science and Technology Securities

The Fund invests in common stocks of science and technology companies and will concentrate in the group of industries constituting the technology sector and may concentrate in one or more industries in the technology sector. The Fund will therefore be susceptible to adverse economic, business, regulatory and other occurrences affecting the technology sector and science and technology companies. In particular, science and technology companies are vulnerable to market saturation and rapid product obsolescence. Many science and technology companies operate under constantly changing fields and have limited business lines and limited financial resources, making them highly vulnerable to business and economic risks. Other investment risks associated with investing in science and technology securities include abrupt or erratic market movements, management that is dependent on a limited number of people, short product cycles, changing consumer preferences, aggressive pricing of products and services, new market entrants, and dependency on patent protection.

E. Line of Credit

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

DWS Science and Technology Fund | 31

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 20 percent of its net assets under the agreement. The Fund had no outstanding loans at April 30, 2019.

Information About Your Fund’s Expenses

As an investor of the Fund, 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 sales charges (loads) and 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. 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 (November 1, 2018 to April 30, 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 Classes A, C and 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 Classes A, C and S 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 Science and Technology Fund’s (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

DWS Science and Technology Fund | 35

invest or remain invested in the Fund knowing that DIMA managed the 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 market index(es) and a peer universe compiled using information supplied by Morningstar Direct (“Morningstar”), 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-, three- and five-year periods ended December 31, 2017, the Fund’s performance (Class A shares) was in the 2nd quartile, 4th quartile and 4th quartile, respectively, of the applicable Morningstar universe (the 1st quartile being the best performers and the 4th quartile being the worst performers). The Board also observed that the Fund has underperformed its benchmark in the one-, three- and five-year periods ended December 31, 2017. The

36 | DWS Science and Technology Fund

Board noted the disappointing investment performance of the Fund in some past periods and continued to discuss with senior management of DIMA the factors contributing to such underperformance and actions being taken to improve performance. The Board observed that the Fund had experienced improved relative performance in 2017 and during the first eight months of 2018. The Board recognized the efforts by DIMA in recent years to enhance its investment platform and improve long-term performance across the DWS fund complex.

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 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 lower than the median (1st quartile) of the applicable Broadridge peer group (based on Broadridge data provided as of December 31, 2017). The Board noted that the Fund’s Class A shares total (net) operating expenses (excluding 12b-1 fees) were expected to be lower than the median (1st quartile) of the applicable Broadridge expense universe (based on Broadridge data provided as of December 31, 2017, and analyzing Broadridge expense universe Class A (net) expenses less any applicable 12b-1 fees) (“Broadridge Universe Expenses”). The Board also reviewed data comparing each share class’s total (net) operating expenses to the applicable Broadridge Universe Expenses. The Board noted that the expense limitations agreed to by DIMA were expected to help the Fund’s total (net) operating expenses remain competitive. The Board considered the Fund’s management fee rate as compared to fees charged by DIMA to a comparable DWS U.S. registered fund (“DWS Funds”) and considered differences between the Fund and the comparable DWS Fund. 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.

DWS Science and Technology Fund | 37

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 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.
