A LETTER FROM THE PRESIDENT OF BNY MELLON INVESTMENT ADVISER, INC.

Dear Shareholder:

We are pleased to present this annual report for BNY Mellon Opportunistic Municipal Securities Fund (formerly, Dreyfus Municipal Bond Opportunity Fund), covering the 12-month period from May 1, 2019 through April 30, 2020. For information about how the fund performed during the reporting period, as well as general market perspectives, we provide a Discussion of Fund Performance on the pages that follow.

Early in the reporting period, equity markets benefited from the U.S. Federal Reserve’s (the “Fed”) accommodative interest rate policy. Trade tensions between the U.S. and China flared periodically, disrupting markets, but the pace of U.S. economic growth remained steady, and stocks rose in mid-2019. Volatility returned in the later summer and early fall, when investors grew concerned about slowing global growth, leading the Fed to cut the federal funds rate in July, September and October 2019. The rate cuts helped to support stock prices, which rallied through the end of the calendar year. The announcement of a “phase one” trade deal between the U.S. and China also worked to bolster valuations. Early in 2020, concerns about COVID-19 roiled markets, compounded by an oil price war between Saudi Arabia and Russia. Stocks posted historic losses in March 2020 but regained some ground in April.

Fixed-income markets benefited from Fed interest rate cuts and from investor concerns about an economic slowdown. Responding to global sluggishness, the Fed reduced rates three times in 2019, which worked to bolster valuations of some fixed income instruments. However, as stocks subsequently rallied, Treasury prices declined, and rates across much of the yield curve rose until early in 2020, when the threat posed by COVID-19 began to emerge. A flight to quality ensued, and rates fell significantly. March 2020 brought high volatility and risk-asset spreads widened. The Fed cut rates twice in March, and the government launched a large stimulus package. In April 2020, bond prices began to recover some of their prior losses.

The near-term outlook for the U.S. will be challenging, as the country continues to face COVID-19. However, we believe that once the economic effects have been mitigated, the economy will rebound. As always, we will monitor relevant data for any signs of a change. We encourage you to discuss the risks and opportunities in today’s investment environment with your financial advisor.

Thank you for your continued confidence and support.

Sincerely,

Renee LaRoche-Morris
President
BNY Mellon Investment Adviser, Inc.

DISCUSSION OF FUND PERFORMANCE(Unaudited)

For the period from May 1, 2019 through April 30, 2020, as provided by Daniel Rabasco and Jeffrey Burger, Portfolio Managers

Market and Fund Performance Overview

For the 12-month period ended April 30, 2020, BNY Mellon Opportunistic Municipal Securities Fund’s (formerly, Dreyfus Municipal Bond Opportunity Fund) Class A shares produced a total return of 0.32%, Class C shares returned -0.46%, Class I shares returned 0.57%, Class Y shares returned 0.57% and Class Z shares returned 0.37%.¹ In comparison, the Bloomberg Barclays U.S. Municipal Bond Index (the “Index”), the fund’s benchmark index, achieved a total return of 2.16% for the same period.²

Municipal bonds experienced turmoil during the reporting period due to the COVID-19 virus. The fund underperformed the Index, largely due to unfavorable asset allocation and security selection.

The Fund’s Investment Approach

The fund seeks to maximize current income exempt from federal income tax to the extent consistent with the preservation of capital. To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in municipal bonds that provide income exempt from federal income tax. Typically, the fund invests substantially all of its assets in such municipal bonds. The fund invests at least 70% of its assets in municipal bonds rated, at the time of purchase, investment grade (i.e.,Baa/BBB or higher) or the unrated equivalent as determined by BNY Mellon Investment Adviser, Inc. For additional yield, the fund may invest up to 30% of its assets in municipal bonds rated below investment grade (“high yield” or “junk” bonds) or the unrated equivalent as determined by BNY Mellon Investment Advisor, Inc. The dollar-weighted, average maturity of the fund’s portfolio normally exceeds ten years, but the fund may invest without regard to maturity or duration.

The fund’s portfolio managers focus on identifying undervalued sectors and securities and minimize the use of interest rate forecasting. The portfolio managers select municipal bonds for the fund’s portfolio by using fundamental credit analysis to estimate the relative value and attractiveness of various sectors and securities and to exploit pricing inefficiencies in the municipal bond market, and by actively trading among various sectors, such as pre-refunded, general obligation and revenue, based on their apparent relative values. The fund seeks to invest in several of these sectors.

COVID-19 Concerns and Supply-Demand Factors Drove Municipal Bonds

Through most of the reporting period, the municipal bond market benefited from strong demand resulting from concerns about domestic economic growth. Demand was also driven by investors in states with high income tax rates. These investors moved into municipal bonds as a way to reduce their federal income tax liability, which rose as a result of the cap on the federal deductibility of state and local taxes in the Tax Cuts and Jobs Act of 2017.

DISCUSSION OF FUND PERFORMANCE(Unaudited) (continued)

Actions by the Federal Reserve (the “Fed”) midway through the period, including three rate cuts, also helped performance in the municipal bond market. This contributed to a decline in yields across the municipal bond yield curve, though investors largely favored longer-term issues, causing the municipal bond yield curve to flatten.

Performance of the market was also assisted by a manageable supply of new bonds. Supply increased somewhat during the reporting period as low interest rates led issuers to seek to capture favorable financing.

The municipal bond market continued to perform well early in 2020 until the emergence of the COVID-19 crisis, which resulted in turmoil and hindered returns, particularly in March 2020. Actions by the Fed, including two emergency rate cuts in March 2020, provided some support to the municipal bond market, but technical supply and demand factors became the predominant drivers.

Though the municipal bond market often benefits from economic uncertainty, in this environment that was not the case. Fears of widespread economic damage due to COVID-19 caused investors to shift out of the municipal bond market, resulting in large outflows from municipal bond mutual funds. In a normal market, broker-dealers would step in to buy municipal bonds. But a decline in the municipal bond market, combined with a rally in the Treasury market, prevented them from hedging their municipal bond purchases by shorting Treasuries, as they normally do.

In addition, the municipal bond market was hurt by the inability of large investors to capitalize on the volatility. As municipal bond yields rose, insurance companies and other large investors were expected to step in, but since there was also a lack of liquidity in corporate bonds, which normally would have financed their municipal bond purchases, these investors were hindered by their inability to act. As a result, the municipal market yield spreads rose significantly, weakening performance.

Fundamentals in the municipal bond market generally remained healthy during the reporting period. Steady but slower economic growth through most of the period supported tax revenues, fiscal balances and “rainy day” funds.

Security Selection and Asset Allocation Drove Fund Results

The fund’s performance versus the Index was hindered during the reporting period by the asset allocation and security selection. The fund’s underweight position in general obligation bonds and overweight position in revenue bonds contributed negatively to performance. Spreads widened particularly in lower-quality revenue bonds and in the education, health care, housing and special tax sectors. Security selection, especially in the education, health care and special tax sectors also detracted from performance.

On a more positive note, the fund’s longer duration was advantageous to performance. Holdings in the power and transportation sectors also performed better than other sectors. There were no derivatives used during the reporting period.

An Emphasis on Quality

We expect the municipal bond market to remain challenged for a while, but the Coronavirus Aid Relief and Security (CARES) Act will provide some relief to the economy, and the Fed’s bond purchasing program will provide support to the market. However, uncertainty about the economic and municipal credit impact of COVID-19 will continue over the near term. Additional support from Congress in the form of a Phase 4 relief package may boost investor confidence in the municipal bond market and also encourage broker-dealers to return as intermediaries.

We will continue to emphasize revenue bonds with sound fundamentals, and we expect to keep the fund’s duration long relative to the benchmark.

¹ Total return includes reinvestment of dividends and any capital gains paid and does not take into consideration the maximum initial sales charge in the case of Class A shares or the applicable contingent deferred sales charge imposed on redemptions in the case of Class C shares. Had these charges been reflected, returns would have been lower. Class I, Class Y, and Class Z are not subject to any initial or deferred sales charge. Past performance is no guarantee of future results. Share price, yield, and investment return fluctuate such that upon redemption, fund shares may be worth more or less than their original cost. Income may be subject to state and local taxes, and some income may be subject to the federal alternative minimum tax (AMT) for certain investors. Capital gains, if any, are taxable.

² Source: Lipper Inc. — The Bloomberg Barclays U.S. Municipal Bond Index covers the U.S. dollar-denominated, long-term, tax-exempt bond market. Investors cannot invest directly in any index.

Bonds are subject generally to interest-rate, credit, liquidity and market risks, to varying degrees, all of which are more fully described in the fund’s prospectus. Generally, all other factors being equal, bond prices are inversely related to interest-rate changes, and rate increases can cause price declines.

The amount of public information available about municipal bonds is generally less than that for corporate equities or bonds. Special factors, such as legislative changes, and state and local economic and business developments, may adversely affect the yield and/or value of the fund’s investments in municipal bonds. Other factors include the general conditions of the municipal bond market, the size of the particular offering, the maturity of the obligation and the rating of the issue. Changes in economic, business or political conditions relating to a particular municipal project, municipality or state in which the fund invests may have an impact on the fund’s share price.

Recent market risks include pandemic risks related to COVID-19. The effects of COVID-19 have contributed to increased volatility in global markets and will likely affect certain countries, companies, industries and market sectors more dramatically than others. To the extent the fund may overweight its investments in certain countries, companies, industries or market sectors, such positions will increase the fund’s exposure to risk of loss from adverse developments affecting those countries, companies, industries or sectors.

NOTES TO FINANCIAL STATEMENTS

NOTE 1—Significant Accounting Policies:

BNY Mellon Opportunistic Municipal Securities Fund (the “fund”), which is registered under the Investment Company Act of 1940, as amended (the “Act”), is a diversified open-ended management investment company. The fund’s investment objective is to seek to maximize current income exempt from federal income tax to the extent consistent with the preservation of capital. BNY Mellon Investment Adviser, Inc. (the “Adviser”), a wholly-owned subsidiary of The Bank of New York Mellon Corporation (“BNY Mellon”), serves as the fund’s investment adviser.

Effective June 3, 2019, the fund changed its name from Dreyfus Municipal Bond Opportunity Fund to BNY Mellon Opportunistic Municipal Securities Fund. In addition, The Dreyfus Corporation, the fund’s investment adviser, changed its name to “BNY Mellon Investment Adviser, Inc.”, MBSC Securities Corporation, the fund’s distributor, changed its name to “BNY Mellon Securities Corporation” and Dreyfus Transfer, Inc., the fund’s transfer agent, changed its name to “BNY Mellon Transfer, Inc.”

The fund’s Board of Trustees (the “Board”) approved, effective December 31, 2019 (the “Effective Date”), the termination of the fund’s authorized Class T shares. Prior to the Effective Date, the fund did not offer such Class T shares for purchase.

BNY Mellon Securities Corporation (the “Distributor”), a wholly-owned subsidiary of the Adviser, is the distributor of the fund’s shares. The fund is authorized to issue an unlimited number of $.001 par value shares of Beneficial Interest in each of the following classes of shares: Class A, Class C, Class I, Class Y and Class Z. Class A shares generally are subject to a sales charge imposed at the time of purchase. Class C shares are subject to a contingent deferred sales charge (“CDSC”) imposed on Class C shares redeemed within one year of purchase. Class C shares automatically convert to Class A shares ten years after the date of purchase, without the imposition of a sales charge. Class I and Class Y shares are sold at net asset value per share generally to institutional investors. Class Z shares are sold at net asset value per share to certain shareholders of the fund. Class Z shares generally are not available for new accounts. Other differences between the classes include the services offered to and the expenses borne by each class, the allocation of certain transfer agency costs, and certain voting rights. Income, expenses (other than expenses attributable to a specific class), and realized and unrealized gains or losses on investments are allocated to each class of shares based on its relative net assets.

NOTES TO FINANCIAL STATEMENTS(continued)

As of April 30, 2020, MBC Investments Corp., an indirect subsidiary of BNY Mellon, held all of outstanding shares of Class Y shares of the fund.

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under authority of federal laws are also sources of authoritative GAAP for SEC registrants. The fund is an investment company and applies the accounting and reporting guidance of the FASB ASC Topic 946 Financial Services-Investment Companies. The fund’s financial statements are prepared in accordance with GAAP, which may require the use of management estimates and assumptions. Actual results could differ from those estimates.

The fundenters into contracts that contain a variety of indemnifications. The fund’s maximum exposure under these arrangements is unknown. The fund does not anticipate recognizing any loss related to these arrangements.

(a) Portfolio valuation: The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., the exit price). GAAP establishes a fair value hierarchy that prioritizes the inputs of valuation techniques used to measure fair value. This hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Additionally, GAAP provides guidance on determining whether the volume and activity in a market has decreased significantly and whether such a decrease in activity results in transactions that are not orderly. GAAP requires enhanced disclosures around valuation inputs and techniques used during annual and interim periods.

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements. These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for identical investments.

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. Valuation techniques used to value the fund’s investments are as follows:

Investments in securities are valued each business day by an independent pricing service (the “Service”) approved by the fund’s Board. Investments for which quoted bid prices are readily available and are representative of the bid side of the market in the judgment of the Service are valued at the mean between the quoted bid prices (as obtained by the Service from dealers in such securities) and asked prices (as calculated by the Service based upon its evaluation of the market for such securities). Debt investments (which constitute a majority of the portfolio securities) are carried at fair value as determined by the Service, based on methods which include consideration of the following: yields or prices of municipal securities of comparable quality, coupon, maturity and type; indications as to values from dealers; and general market conditions. All of the preceding securities are generally categorized within Level 2 of the fair value hierarchy.

The Service is engaged under the general oversight of the Board.

When market quotations or official closing prices are not readily available, or are determined not to accurately reflect fair value, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the fund calculates its net asset value, the fund may value these investments at fair value as determined in accordance with the procedures approved by the Board. Certain factors may be considered when fair valuing investments such as: fundamental analytical data, the nature and duration of restrictions on disposition, an evaluation of the forces that influence the market in which the securities are purchased and sold, and public trading in similar securities of the issuer or comparable issuers. These securities are either categorized within Level 2 or 3 of the fair value hierarchy depending on the relevant inputs used.

For securities where observable inputs are limited, assumptions about market activity and risk are used and such securities are generally categorized within Level 3 of the fair value hierarchy.

NOTES TO FINANCIAL STATEMENTS(continued)

The following is a summary of the inputs used as of April 30, 2020in valuing the fund’s investments:


Assets ($)	Level 1 - Unadjusted Quoted Prices	Level 2 - Other Significant Observable Inputs	Level 3 - Significant Unobservable Inputs	Total
Investments in Securities:^†
Collateralized Municipal-Backed Securities	−	986,802	−	986,802
Municipal Securities	−	362,953,596	−	362,953,596

^† See Statement of Investments for additional detailed categorizations, if any.

(b) Securities transactions and investment income: Securities transactions are recorded on a trade date basis. Realized gains and losses from securities transactions are recorded on the identified cost basis. Interest income, adjusted for accretion of discount and amortization of premium on investments, is earned from settlement date and recognized on the accrual basis. Securities purchased or sold on a when issued or delayed delivery basis may be settled a month or more after the trade date.

(c) Risk: Certain events particular to the industries in which the fund’s investments conduct their operations, as well as general economic, political and public health conditions, may have a significant negative impact on the investee’s operations and profitability. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the fund. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies world-wide. Recent examples include pandemic risks related to COVID-19 and aggressive measures taken world-wide in response by governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines of large populations, and by businesses, including changes to operations and reducing staff. To the extent the fund may overweight its investments in certain countries, companies, industries or market sectors, such positions will increase the fund’s exposure to risk of loss from adverse developments affecting those countries, companies, industries or sectors.

(d) Dividends and distributions to shareholders:It is the policy of the fund to declare dividends daily from investment income-net. Such

dividends are paid monthly. Dividends from net realized capital gains, if any, are normally declared and paid annually, but the fund may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Code”). To the extent that net realized capital gains can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gains. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

(e) Federal income taxes: It is the policy of the fund to continue to qualify as a regulated investment company, which can distribute tax-exempt dividends, by complying with the applicable provisions of the Code, and to make distributions of income and net realized capital gain sufficient to relieve it from substantially all federal income and excise taxes.

As of and during the period ended April 30, 2020, the fund did not have any liabilities for any uncertain tax positions. The fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statement of Operations. During the period ended April 30, 2020, the fund did not incur any interest or penalties.

Each tax year in the four-year period ended April 30, 2020 remains subject to examination by the Internal Revenue Service and state taxing authorities.

At April 30, 2020, the components of accumulated earnings on a tax basis were as follows: undistributed tax-exempt income $698,216, undistributed ordinary income $20,858, undistributed capital gains $802,325 and unrealized appreciation $4,540,997.

The tax character of distributions paid to shareholders during the fiscal periods ended April 30, 2020 and April 30, 2019 were as follows: tax-exempt income $10,241,317 and $10,202,806, and ordinary income $0 and $184,283, respectively.

During the period ended April 30, 2020, as a result of permanent book to tax differences, primarily due to the tax treatment for amortization adjustments, the fund decreased total distributable earnings (loss) by $3,900 and increased paid-in capital by the same amount. Net assets and net asset value per share were not affected by this reclassification.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Trustees of BNY Mellon Opportunistic Municipal Securities Fund

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of BNY Mellon Opportunistic Municipal Securities Fund (the “Fund”), including the statement of investments, as of April 30, 2020, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund at April 30, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and its financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of the Fund’s internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of April 30, 2020, by correspondence with the custodian and others or by other appropriate auditing procedures where replies from others were not received. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more investment companies in the BNY Mellon Family of Funds since at least 1957, but we are unable to determine the specific year.
