To Our Shareholders:

We would like to share with you our report for the year ended November 30, 2023. The total returns for Cohen & Steers MLP & Energy Opportunity Fund, Inc. (the Fund) and its comparative benchmarks were:

	Six Months Ended November 30, 2023			Year Ended November 30, 2023
Cohen & Steers MLP & Energy Opportunity Fund, Inc.:
Class A		13.82	%		3.68	%
Class C		13.48	%		3.09	%
Class I		14.00	%		4.04	%
Class R		13.83	%		3.62	%
Class Z		13.98	%		4.04	%
Blended Benchmark(a)		15.11	%		5.18	%
S&P 500 Index(a)		10.17	%		13.84	%

The performance data quoted represent past performance. Past performance is no guarantee of future results. The investment return and the principal value of an investment will fluctuate and shares, if redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data quoted. Current total returns of the Fund can be obtained by visiting our website at cohenandsteers.com. All share class returns assume the reinvestment of all dividends and distributions at net asset value (NAV). Fund performance figures reflect fee waivers and/or expense reimbursements, without which the performance would have been lower. Performance quoted does not reflect the deduction of the maximum 4.50% initial sales charge on Class A shares or the 1.00% maximum contingent deferred sales charge on Class C shares. The 1.00% maximum contingent deferred sales charge on Class C shares applies if redemption occurs on or before the one year anniversary date of their purchase. If such charges were included, returns would have been lower. Index performance does not reflect the deduction of any fees, taxes or expenses. An investor cannot invest directly in an index. Performance figures for periods shorter than one year are not annualized.

Please note that all distributions paid by the Fund to shareholders are subject to recharacterization for tax purposes and are taxable up to the amount of the Fund’s investment company taxable income and net realized gains. Distributions in excess of the Fund’s investment company taxable income and net realized gains are “return of capital” distributed from the Fund’s assets. Return of capital distributions decrease the Fund’s total assets and, therefore, could have the effect of increasing the Fund’s expense ratio.

Market Review

Midstream energy securities and master limited partnerships (MLPs) had a positive total return in the 12 months ended November 30, 2023, but trailed the broader equity market. The period was marked by volatile energy commodity prices, a deceleration in inflation, and uncertainty around the economy that ultimately gave way to a more optimistic outlook as growth (and demand for energy products) exceeded expectations.

The debt markets experienced volatility (which at times weighed on share prices) as the Federal Reserve (Fed) continued to raise its benchmark lending rate through July. For much of the year, gains in the equity market were primarily concentrated in the technology sector, driven by the prospects for generative artificial intelligence (AI). However, the rally broadened amid rising expectations for an economic “soft landing” and the possible conclusion of the Fed’s credit tightening cycle.

Initially, midstream companies were hampered by the continued downward move in energy prices from the high levels seen in mid-2022. An uncertain macro outlook clouded the demand picture for crude oil, which, combined with higher-than-anticipated supply from Russia and Iran, weighed on oil prices. Concurrently, natural gas prices plummeted later in the year as supply growth continued to outpace demand, keeping global storage levels elevated. However, midstream share prices strengthened in the second half of the year.

Throughout the year, midstream companies generally reported positive earnings, with most either meeting or exceeding expectations. Companies remained consistent in their messaging on capital expenditure controls and a return of cash to shareholders. Stock buybacks typically consisted of companies taking advantage of price weakness rather than buying programmatically. The industry also witnessed continued consolidation in 2023, with larger, well-capitalized names acquiring smaller companies with limited organic growth prospects. Most transactions included embedded takeout premiums, though there were examples of deals occurring at no premium.

Within the midstream space, MLPs outperformed companies structured as corporations. The latter category includes Canadian midstream companies, which operate in a relatively commodity price—exposed economy and generally have higher leverage (and thus are sensitive to a rising—interest rate environment).

Fund Performance

The Fund had a positive total return in the period but underperformed its blended benchmark.

The refining sector posted a strong total return as companies benefited from wide crack spreads (i.e., the price difference between a barrel of crude oil and finished petroleum products). The Fund’s underweight allocation in the sector detracted from relative performance. However, the adverse effect of the underweight was mitigated by favorable security selection in the sector.

The gathering and gathering & processing sectors, known for their sensitivity to commodity prices through changes in volume expectations, outperformed against a backdrop of high and relatively stable crude oil prices. The gathering sector also saw positive developments as a long—beleaguered pipeline project in Virginia received federal approval for completion, which was seen as a positive for U.S. gas production and related midstream companies. The Fund’s overweight allocation and security selection

2

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

in gathering & processing contributed to relative performance. Although our stock selection in the gathering sector also modestly contributed to relative returns, this positive effect was outweighed by unfavorable timing in our sector allocations.

The liquefied natural gas (LNG) exports sector concluded the period with a small positive total return. Amid full inventories, moderate weather dampened demand for LNG, considerably narrowing the once wide spread between U.S. and global LNG prices. Despite the oversupplied market, investors anticipated that new LNG facilities entering into service in 2024 and 2025 would enhance exporters’ ability to serve global markets. The Fund’s security selection in the LNG exports sector contributed to relative performance.

Utilities, which tend to be sensitive to rising interest rates, declined in the period. Despite these companies’ ability to pass costs along to customers, concerns about companies relying on external funding for growth weighed on the shares. The Fund’s stock selection and underweight allocation in utilities contributed to relative performance.

Natural gas pipelines, represented in the index by a large-capitalization Canadian company, also declined. This company announced that it would sell a minority stake in its U.S. gas pipeline franchise to improve its balance sheet. The company also proposed the spinoff of its liquids pipeline business. The market viewed these transactions as sales of good assets at disappointing multiples. The Fund’s security selection and overweight allocation in natural gas pipelines detracted from relative performance.

The diversified sector, consisting of larger, well-capitalized companies, generally performed well, and companies more focused on crude oil transportation outperformed. The Fund’s underweight allocation in The Williams Companies had a negative impact, as the natural gas—centric stock performed better than the near-term gas outlook would have suggested.

Stocks in the crude/products pipes sector generally performed well due to higher-than-expected demand. However, investors were disappointed by Enbridge’s announcement of a large acquisition of gas distribution assets (funded with equity raised). The Fund’s security selection in the sector aided relative returns, partly due to an underweight investment in Enbridge. However, this positive effect was partially offset by an underweight allocation in the sector.

The water sector performed in line with the benchmark, supported by relatively firm crude oil prices driving drilling activity in the Permian Basin (and thus demand for the water used to fracture rock formations). However, the Fund’s stock selection in the sector hindered relative performance due to an out-of-benchmark position in a small-cap company that underperformed for no apparent reason. The storage/terminals sector had a relatively modest positive total return, and our overweight in the sector hindered relative performance.

Impact of Derivatives on Fund Performance

The Fund engaged in the buying and selling of single stock options with the intention of enhancing total returns and reducing overall volatility. These contracts did not have a material effect on the Fund’s total return for the 12 months ended November 30, 2023.

Name and Investment Strategy Changes

On September 12, 2023, the Board of Directors of the Fund approved a change in the Fund’s name to the Cohen & Steers Future of Energy Fund, Inc. and corresponding changes to the Fund’s principal investment strategies, all of which would become effective at the close of business on March 28, 2024. Following these changes, the Fund’s performance benchmarks will be the S&P Energy Select Sector Index and a blended benchmark consisting of 70% S&P Energy Select Sector Index and 30% S&P North America and Europe Clean Energy Index.

As a result of these changes, effective at the close of business on March 28, 2024, under normal market conditions, the Fund will invest at least 80% of its net assets (plus borrowings for investment purposes) in equity securities of energy companies, including traditional-, alternative-, renewable- and clean-energy companies, natural resource companies, utilities, and companies in associated businesses. The Fund will seek to invest in Energy and Energy-Related Companies that the investment advisor believes are leading, enabling, supplying, disrupting, or otherwise benefiting from transitional or longer-term structural changes to the global energy sector, such as changes resulting from shifting demand and supply of traditional and alternative energy sources, increasing emphasis on storage, resilience, and security of supply, and other developments in technologies, regulations, and behaviors affecting the energy sector.

More information can be found in a separate notice to shareholders that will be mailed to shareholders in advance of these changes.

Sincerely,

BEN MORTON	TYLER S. ROSENLICHT

Expense Example (Unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments; and (2) ongoing costs including investment advisory fees, distribution and/or service (12b-1) fees and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period June 1, 2023—November 30, 2023.

Actual Expenses

The first line of the following table provides information about actual account values and expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that 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 first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the following table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads). Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

NOTES TO FINANCIAL STATEMENTS

Note 1. Organization and Significant Accounting Policies

Cohen & Steers MLP & Energy Opportunity Fund, Inc. (the Fund) was incorporated under the laws of the State of Maryland on July 8, 2013 and is registered under the Investment Company Act of 1940 (the 1940 Act) as a non-diversified, open-end management investment company. The Fund’s investment objective is to provide attractive total return, comprised of current income and price appreciation. The authorized shares of the Fund are divided into six classes designated Class A, C, F, I, R and Z shares. Each of the Fund’s shares has equal dividend, liquidation and voting rights (except for matters relating to distribution and shareholder servicing of such shares). Class F shares are currently not available for purchase.

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The Fund is an investment company and, accordingly, follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board Accounting Standards Codification (ASC) Topic 946—Investment Companies. The accounting policies of the Fund are in conformity with accounting principles generally accepted in the United States of America (GAAP). The preparation of the financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

Portfolio Valuation: Investments in securities that are listed on the New York Stock Exchange (NYSE) are valued, except as indicated below, at the last sale price reflected at the close of the NYSE on the business day as of which such value is being determined. If there has been no sale on such day, the securities are valued at the mean of the closing bid and ask prices on such day or, if no ask price is available, at the bid price. Exchange-traded options are valued at their last sale price as of the close of options trading on applicable exchanges on the valuation date. In the absence of a last sale price on such day, options are valued at the average of the quoted bid and ask prices as of the close of business. Over-the-counter (OTC) options are valued based upon prices provided by a third-party pricing service or counterparty.

Securities not listed on the NYSE but listed on other domestic or foreign securities exchanges (including NASDAQ) are valued in a similar manner. Securities traded on more than one securities exchange are valued at the last sale price reflected at the close of the exchange representing the principal market for such securities on the business day as of which such value is being determined. If after the close of a foreign market, but prior to the close of business on the day the securities are being valued, market conditions change significantly, certain non-U.S. equity holdings may be fair valued pursuant to procedures established by the Board of Directors.

Readily marketable securities traded in the OTC market, including listed securities whose primary market is believed by Cohen & Steers Capital Management, Inc. (the investment advisor) to be OTC, are valued on the basis of prices provided by a third-party pricing service or third-party broker-dealers when such prices are believed by the investment advisor, pursuant to delegation by the Board of Directors, to reflect the fair value of such securities.

Short-term debt securities with a maturity date of 60 days or less are valued at amortized cost, which approximates fair value. Investments in open-end mutual funds are valued at net asset value (NAV).

23

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS—(Continued)

The Board of Directors has designated the investment advisor as the Fund’s “Valuation Designee” under Rule 2a-5 under the 1940 Act. As Valuation Designee, the investment advisor is authorized to make fair valuation determinations, subject to the oversight of the Board of Directors. The investment advisor has established a valuation committee (Valuation Committee) to administer, implement and oversee the fair valuation process according to the policies and procedures approved annually by the Board of Directors. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.

Securities for which market prices are unavailable, or securities for which the investment advisor determines that the bid and/or ask price or a counterparty valuation does not reflect market value, will be valued at fair value, as determined in good faith by the Valuation Committee, pursuant to procedures approved by the Fund’s Board of Directors. Circumstances in which market prices may be unavailable include, but are not limited to, when trading in a security is suspended, the exchange on which the security is traded is subject to an unscheduled close or disruption or material events occur after the close of the exchange on which the security is principally traded. In these circumstances, the Fund determines fair value in a manner that fairly reflects the market value of the security on the valuation date based on consideration of any information or factors it deems appropriate. These may include, but are not limited to, recent transactions in comparable securities, information relating to the specific security and developments in the markets.

Foreign equity fair value pricing procedures utilized by the Fund may cause certain non-U.S. equity holdings to be fair valued on the basis of fair value factors provided by a pricing service to reflect any significant market movements between the time the Fund values such securities and the earlier closing of foreign markets.

The Fund’s use of fair value pricing may cause the NAV of Fund shares to differ from the NAV that would be calculated using market quotations. Fair value pricing involves subjective judgments and it is possible that the fair value determined for a security may be materially different than the value that could be realized upon the sale of that security.

Fair value is defined as the price that the Fund would expect to receive upon the sale of an investment or expect to pay to transfer a liability in an orderly transaction with an independent buyer in the principal market or, in the absence of a principal market, the most advantageous market for the investment or liability. The hierarchy of inputs that are used in determining the fair value of the Fund’s investments is summarized below.

• Level 1—quoted prices in active markets for identical investments

• Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, 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 may or may not be an indication of the risk associated with those investments. Changes in valuation techniques may result in transfers into or out of an assigned level within the disclosure hierarchy.

^(a) Portfolio holdings are disclosed individually on the Schedule of Investments.

Security Transactions, Investment Income and Expense Allocations: Security transactions are recorded on trade date. Realized gains and losses on investments sold are recorded on the basis of identified cost. Dividend income is recorded on the ex-dividend date, except for certain dividends on foreign securities, which are recorded as soon as the Fund is informed after the ex-dividend date. Distributions from common stock and Master Limited Partnerships (MLPs) are recorded as income and return of capital based on information reported by these issuers as well as management’s estimates of such amounts based on historical information. These estimates are adjusted when the actual source of distributions is disclosed by these issuers. Actual amounts may differ from the estimated amounts. For the year ended November 30, 2023, the Fund has estimated approximately 44.0% of distributions from common stock and MLPs as return of capital. 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.

Option Contracts: The Fund may purchase and write exchange-listed and OTC put or call options on securities, stock indices and other financial instruments for hedging purposes, to enhance portfolio returns and/or reduce overall volatility.

When the Fund writes (sells) an option, an amount equal to the premium received by the Fund is recorded on the Statement of Assets and Liabilities as a liability. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written. When an option expires, the Fund realizes a gain on the option to the extent of the premium received. Premiums received from writing options which are exercised or closed are added to or offset against the proceeds

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS—(Continued)

or amount paid on the transaction to determine the realized gain or loss. If a put option on a security is exercised, the premium reduces the cost basis of the security purchased by the Fund. If a call option is exercised, the premium is added to the proceeds of the security sold to determine the realized gain or loss. The Fund, as writer of an option, bears the market risk of an unfavorable change in the price of the underlying investment. Other risks include the possibility of an illiquid options market or the inability of the counterparties to fulfill their obligations under the contracts.

Put and call options purchased are accounted for in the same manner as portfolio securities. Premiums paid for purchasing options which expire are treated as realized losses. Premiums paid for purchasing options which are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying investment transaction to determine the realized gain or loss when the underlying transaction is executed. The risk associated with purchasing an option is that the Fund pays a premium whether or not the option is exercised. Additionally, the Fund bears the risk of loss of the premium and change in market value should the counterparty not perform under the contract.

Master Limited Partnerships: Entities commonly referred to as MLPs are generally organized under state law as limited partnerships or limited liability companies. The Fund invests in MLPs receiving partnership taxation treatment under the Internal Revenue Code of 1986, as amended (the Code), and whose interest or “units” are traded on securities exchanges like shares of corporate stock. To be treated as a partnership for U.S. federal income tax purposes, an MLP whose units are traded on a securities exchange must receive at least 90% of its income from qualifying sources such as interest, dividends, real property rents, gains on dispositions of real property, income and gains from mineral or natural resources activities, income and gains from the transportation or storage of certain fuels, and, in certain circumstances, income and gains from commodities or futures, forwards and options on commodities. Mineral or natural resources activities include exploration, development, production, processing, mining, refining, marketing and transportation (including pipelines) of oil and gas, minerals, geothermal energy, fertilizer, timber or industrial source carbon dioxide. An MLP consists of a general partner and limited partners (or in the case of MLPs organized as limited liability companies, a managing member and members). The general partner or managing member typically controls the operations and management of the MLP and has an ownership stake in the partnership or limited liability company. The limited partners or members, through their ownership of limited partner or member interests, provide capital to the entity, are intended to have no role in the operation and management of the entity and receive cash distributions. The Fund’s investments in MLPs consist only of limited partner or member interests ownership. The MLPs themselves generally do not pay U.S. federal income taxes and unlike investors in corporate securities, direct MLP investors are generally not subject to double taxation (i.e., corporate level tax and tax on corporate dividends). Currently, most MLPs operate in the energy and/or natural resources sector.

Foreign Currency Translation: The books and records of the Fund are maintained in U.S. dollars. Investment securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars based upon prevailing exchange rates on the date of valuation. Purchases and sales of investment securities and income and expense items denominated in foreign currencies are translated into U.S. dollars based upon prevailing exchange rates on the respective dates of such transactions. The Fund does not isolate that portion of the results of operations resulting from fluctuations in foreign

26

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS—(Continued)

exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss on investments.

Net realized foreign exchange gains or losses arise from sales of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest, and foreign withholding taxes recorded on the Fund’s books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in the values of assets and liabilities, other than investments in securities, on the date of valuation, resulting from changes in exchange rates. Pursuant to U.S. federal income tax regulations, certain foreign currency gains/losses included in realized and unrealized gain/loss are included in or are a reduction of ordinary income for federal income tax purposes.

Dividends and Distributions to Shareholders: Dividends from net investment income and capital gain distributions are determined in accordance with U.S. federal income tax regulations, which may differ from GAAP. Dividends from net investment income, if any, are declared and paid quarterly. Net realized capital gains, unless offset by any available capital loss carryforward, are typically distributed to shareholders at least annually. Dividends and distributions to shareholders are recorded on the ex-dividend date and are automatically reinvested in full and fractional shares of the Fund based on the NAV per share at the close of business on the payable date, unless the shareholder has elected to have them paid in cash. Dividends from net investment income are subject to recharacterization for tax purposes.

Income Taxes: It is the policy of the Fund to continue to qualify as a regulated investment company (RIC), if such qualification is in the best interest of the shareholders, by complying with the requirements of Subchapter M of the Internal Revenue Code applicable to RICs, and by distributing substantially all of its taxable earnings to its shareholders. Also, in order to avoid the payment of any federal excise taxes, the Fund will distribute substantially all of its net investment income and net realized gains on a calendar year basis. Accordingly, no provision for federal income or excise tax is necessary. Dividend and interest income from holdings in non-U.S. securities is recorded net of non-U.S. taxes paid. Management has analyzed the Fund’s tax positions taken on federal and applicable state income tax returns as well as its tax positions in non-U.S. jurisdictions in which it trades for all open tax years and has concluded that as of November 30, 2023, no additional provisions for income tax are required in the Fund’s financial statements. The Fund’s tax positions for the tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service, state departments of revenue and by foreign tax authorities.

Note 2. Investment Advisory Fees, Administration Fees and Other Transactions with Affiliates

Investment Advisory Fees: Cohen & Steers Capital Management, Inc. serves as the Fund’s investment advisor pursuant to an investment advisory agreement (the investment advisory agreement). Under the terms of the investment advisory agreement, the investment advisor provides the Fund with day-to-day investment decisions and generally manages the Fund’s investments in accordance with the stated policies of the Fund, subject to the supervision of the Board of Directors.

For the services provided to the Fund, the investment advisor receives a fee, accrued daily and paid monthly, at the annual rate of 0.80% of the average daily net assets of the Fund.

27

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS—(Continued)

For the year ended November 30, 2023 and through June 30, 2025, the investment advisor contractually agreed to waive its fee and/or reimburse expenses so that the Fund’s total annual operating expenses (excluding acquired fund fees and expenses, taxes and extraordinary expenses), did not exceed 1.25% for Class A shares, 1.90% for Class C shares, 0.90% for Class I shares, 1.40% for Class R shares and 0.90% for Class Z shares. This contractual agreement can only be amended or terminated by agreement of the Fund’s Board of Directors and the investment advisor and will terminate automatically in the event of termination of the investment advisory agreement between the investment advisor and the Fund. For the year ended November 30, 2023, fees waived and/or expenses reimbursed totaled $393,664.

Under subadvisory agreements between the investment advisor and each of Cohen & Steers Asia Limited and Cohen & Steers UK Limited (collectively, the subadvisors), affiliates of the investment advisor, the subadvisors are responsible for managing the Fund’s investments in certain non-U.S. holdings. For their services provided under the subadvisory agreements, the investment advisor (not the Fund) pays the subadvisors. The investment advisor allocates 50% of the investment advisory fee received from the Fund among itself and each subadvisor based on the portion of the Fund’s average daily net assets managed by the investment advisor and each subadvisor.

Administration Fees: The Fund has entered into an administration agreement with the investment advisor under which the investment advisor performs certain administrative functions for the Fund and receives a fee, accrued daily and paid monthly, at the annual rate of 0.05% of the average daily net assets of the Fund. For the year ended November 30, 2023, the Fund incurred $60,281 in fees under this administration agreement. Additionally, the Fund pays State Street Bank and Trust Company as co-administrator under a fund accounting and administration agreement.

Distribution Fees: Shares of the Fund are distributed by Cohen & Steers Securities, LLC (the distributor), an affiliated entity of the investment advisor. The Fund has adopted a distribution plan (the plan) pursuant to Rule 12b-1 under the 1940 Act, which allows the Fund to pay distribution fees for the sale and distribution of its shares. The plan provides that the Fund will pay the distributor a fee, accrued daily and paid monthly, at an annual rate of up to 0.25% of the average daily net assets attributable to Class A shares, up to 0.75% of the average daily net assets attributable to Class C shares and up to 0.50% of the average daily net assets attributable to Class R shares. In addition, with respect to Class R shares, such amounts may also be used to pay for services to Fund shareholders or services related to the maintenance of shareholder accounts.

There is a maximum initial sales charge of 4.50% for Class A shares. There is a contingent deferred sales charge (CDSC) of 1.00% on purchases of $1 million or more of Class A shares, which applies if redemption occurs within one year from purchase. There is a CDSC of 1.00% on Class C shares, which applies if redemption occurs within one year from purchase. For the year ended November 30, 2023, the Fund has been advised that the distributor received $2,566, which represents a portion of the sales commissions paid by shareholders from the sale of Class A shares, and $70 of CDSC relating to redemptions of Class C shares. The distributor has advised the Fund that proceeds from the CDSC on these classes are used by the distributor to defray its expenses related to providing distribution-related services to the Fund in connection with the sale of these classes, including payments to dealers and other financial intermediaries for selling these classes. The payment of a

28

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS—(Continued)

CDSC may result in the distributor receiving amounts greater or less than the upfront commission paid by the distributor to the financial intermediary.

Shareholder Servicing Fees: For shareholder services, the Fund pays the distributor or its affiliates a fee, accrued daily, at an annual rate of up to 0.10% of the average daily net assets of the Fund’s Class A and Class I shares and up to 0.25% of the average daily net assets of the Fund’s Class C shares. The distributor is responsible for paying qualified financial institutions for shareholder services.

Directors’ and Officers’ Fees: Certain directors and officers of the Fund are also directors, officers and/or employees of the investment advisor. The Fund does not pay compensation to directors and officers affiliated with the investment advisor except for the Chief Compliance Officer, who received compensation from the investment advisor, which was reimbursed by the Fund, in the amount of $856 for the year ended November 30, 2023.

Note 3. Purchases and Sales of Securities

Note 7. Other Risks

MLP Investment Risk: An investment in MLPs involves risks that differ from a similar investment in equity securities, such as common stock, of a corporation. Holders of equity securities issued by MLPs have the rights typically afforded to limited partners in a limited partnership. As compared to common shareholders of a corporation, holders of such equity securities have more limited control and limited rights to vote on matters affecting the partnership. MLPs may have additional expenses, as some MLPs pay incentive distribution fees to their general partners. Additionally, conflicts of interest may exist among common unit holders, subordinated unit holders and the general partner or managing member of an MLP; for example, a conflict may arise as a result of incentive distribution payments.

MLPs may have comparatively smaller capitalizations relative to issuers whose securities are included in major benchmark indexes which presents unique investment risks. MLPs and other small capitalization companies often have limited product lines, markets, distribution channels or financial resources, and the management of such companies may be dependent upon one or a few key people. The market movements of equity securities issued by MLPs and other small capitalization companies may be more abrupt or erratic than the market movements of equity securities of larger, more established companies or the stock market in general. MLPs and other smaller capitalization companies have sometimes gone through extended periods when they did not perform as well as larger companies. In addition, equity securities of smaller capitalization companies generally are less liquid than those of larger companies. This means that the Fund could have greater difficulty selling such securities at the time and price that the Fund would like.

32

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS—(Continued)

MLPs are subject to significant regulation and may be adversely affected by changes in the regulatory environment. The value of MLPs depends largely on the MLPs being treated as partnerships for U.S. federal income tax purposes. If MLPs were subject to U.S. federal income taxation as a corporation, the MLPs would be required to pay U.S. federal income tax on their taxable income which would have the effect of reducing the amount of cash available for distribution to the MLP unitholders. This would also cause any such distributions received by the Fund to be taxed as dividend income to the extent of the MLP’s current or accumulated earnings and profits. As a result, after-tax returns could be reduced, which could cause a decline in the value of MLPs.

Energy Sector Risk: The Fund is subject to more risks related to the energy sector than if the Fund were more broadly diversified over numerous sectors of the economy. A downturn in the energy sector of the economy could have a larger impact on the Fund than on an investment company that does not concentrate in the sector. Recent uncertainty in the energy markets has had an adverse effect on energy related securities, including MLPs, and it is unclear when these markets may stabilize. In addition, there are several specific risks associated with investments in the energy sector, including the following: Commodity Price Risk, Depletion Risk, Supply and Demand Risk, Regulatory Risk, Acquisition Risk, Weather Risks, Exploration Risk, Catastrophic Event Risk, Interest Rate Transaction Risk, Affiliated Party Risk and Limited Partner Risk and Risks of Subordinated MLP Units. MLPs which invest in the energy industry may be highly volatile due to significant fluctuation in the prices of energy commodities as well as political and regulatory developments.

Market Volatility Risk: Under normal market conditions, the Fund will invest at least 80% of its net assets in energy-related MLPs and companies that are involved in the exploration, production, gathering, transportation, processing, storage, refining, distribution or marketing of natural gas, natural gas liquids (including propane), crude oil, refined petroleum products, coal or other energy sources (Related Companies). The Fund’s strategy of focusing its investments in MLPs and Related Companies means that the performance of the Fund will be closely tied to the performance of the energy infrastructure industry. Recent market volatility in the energy markets, including price decreases connected to the COVID-19 pandemic, has significantly affected the performance of the energy infrastructure industry, as well as the performance of the MLPs and Related Companies in which the Fund invests. In addition, volatility in the energy markets may affect the ability of MLPs and Related Companies to finance capital expenditures and new acquisitions and to maintain or increase distributions to investors due to a lack of access to capital.

Utilities Sector Risks: Companies in the utilities sector are subject to a variety of factors that may adversely affect their business or operations, including high interest costs associated with capital construction and improvement programs; difficulty in raising adequate capital in periods of high inflation and unsettled capital markets; governmental regulation of rates the issuer can charge to customers; costs associated with compliance with environmental and other regulations; effects of economic slowdowns and surplus capacity; the potential impact of natural disasters and terrorist attacks on the utility industry and its customers; increased competition; potential losses resulting from a changes in regulations; and liabilities for environmental damage and general civil liabilities.

Clean Energy Risk: Many clean energy companies are involved in the development and commercialization of new technologies, which may be subject to delays resulting from budget

33

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS—(Continued)

constraints, technological difficulties, or public and regulatory opposition. Clean energy companies may be highly dependent upon government subsidies, contracts with government entities, and the successful development of new and proprietary technologies. In addition, seasonal weather conditions, fluctuations in the supply of and demand for clean energy products, changes in energy prices, and international political events may cause fluctuations in the performance of clean energy companies and the prices of their securities.

Renewable Companies Risk: Renewable companies may be subject to a variety of factors that may adversely affect their business or operations, including costs and losses associated with environmental and other regulations and enforcement policies or changes thereto, obsolescence of its existing offerings, the effects of economic slowdown, short production cycles, increased competition from other providers of services, the effects of energy conservation policies and other factors.

Because many renewable companies may be concentrated in a particular industry or industry sector (for example, the energy sector), they are subject to risks associated with such industry or sector. Renewable energy companies may be more volatile than companies operating in more established industries. Renewable energy companies and other companies operating in the renewable energy group of industries are subject to specific risks, including, among others: fluctuations in commodity prices and/or interest rates; the success of research or exploration projects, changes in governmental or environmental regulation; reduced availability of renewable energy sources or other commodities for transporting, processing, storing or delivering resources; slowdowns in new construction; seasonal weather conditions, extreme weather or other natural disasters; and threats of attack by terrorists on certain clean energy assets. Additionally, the industry also can be significantly affected by the supply of and demand for specific products or services, including the supply of and demand and price of traditional energy sources (e.g., oil and gas).

Interest Rate Risk to Energy and Energy-Related Companies Risk: Rising interest rates could increase the costs of capital thereby increasing operating costs and reducing the ability of Energy and Energy-Related Companies to carry out acquisitions or expansions in a cost-effective manner. As a result, rising interest rates could negatively affect the financial performance of Energy and Energy-Related Companies. Rising interest rates may also impact the price of the securities of Energy and Energy-Related Companies as the yields on alternative investments increase.

Tax Risk: The Fund intends to qualify each year as a RIC for U.S. federal income tax purposes under Subchapter M of the Code. For any year in which the Fund so qualifies, it will not be subject to U.S. federal income tax on income or gain that it timely distributes to shareholders as dividends. In order to qualify as a RIC, the Fund must meet certain asset diversification requirements, including that, at the close of each quarter of its taxable year, no more than 25% of its total assets will be invested in Qualified Publicly Traded Partnerships (QPTPs). The Fund expects that the MLPs that are treated as publicly traded partnerships for tax purposes in which the Fund invests will generally be QPTPs. The treatment of certin of the Fund’s investments for purposes of this test may be unclear, and it is possible that the Internal Revenue Service (IRS) or a court could recharacterize one or more such investments in a maner bearing adversely on the Fund’s ability to meet this 25% requirement. As of November 30, 2023, the Fund held 18% of total assets in QPTPs.

34

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS—(Continued)

Non-corporate taxpayers are permitted to deduct a portion of any income derived from an interest in an MLP that constitutes “qualified publicly traded partnership income.” This deduction is not available in respect of any such income that is allocated to or reflected in net recapture income realized by a RIC in respect of its interest in an MLP, and distributed by the RIC to its shareholders. As a result, it is possible that a non-corporate shareholder will be subject to a higher effective tax rate on any such distributions received from the Fund compared to the effective rate applicable to any qualified publicly traded partnership income the shareholder would derive if the shareholder invested directly in an MLP.

Geopolitical Risk: Occurrence of global events similar to those in recent years, such as war (including Russia’s military invasion of Ukraine), terrorist attacks, natural or environmental disasters, country instability, infectious disease epidemics or pandemics, such as that caused by COVID-19, market instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers and other governmental trade or market control programs, the potential exit of a country from its respective union and related geopolitical events, may result in market volatility and may have long-lasting impacts on U.S. and global economies and financial markets. Supply chain disruptions or significant changes in the supply or prices of commodities or other economic inputs may have material and unexpected effects on both global securities markets and individual countries, regions, sectors, companies or industries. Events occurring in one region of the world may negatively impact industries and regions that are not otherwise directly impacted by the events. Additionally, those events, as well as other changes in foreign and domestic political and economic conditions, could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, secondary trading, credit ratings, inflation, investor sentiment and other factors affecting the value of the Fund’s investments.

Although the long-term economic fallout of COVID-19 is difficult to predict, it has contributed to, and may continue to contribute to, market volatility, inflation and systemic economic weakness. COVID-19 and efforts to contain its spread may also exacerbate other pre-existing political, social, economic, market and financial risks. In addition, the U.S. government and other central banks across Europe, Asia, and elsewhere announced and/or adopted economic relief packages in response to COVID-19. The end of any such program could cause market downturns, disruptions and volatility, particularly if markets view the ending as premature. The U.S. federal government ended the COVID-19 public emergency declaration on May 11, 2023, however, the effects of the COVID-19 pandemic are expected to continue and the risk that new variants of COVID-19 may emerge remains. Therefore the economic outlook, particularly for certain industries and businesses, remains inherently uncertain.

On January 31, 2020, the United Kingdom (UK) withdrew from the European Union (EU) (referred to as Brexit). An agreement between the UK and the EU governing their future trade relationship became effective January 1, 2021. Brexit has resulted in volatility in European and global markets and could have potentially significant negative long-term impacts on financial markets in the UK and throughout Europe.

On February 24, 2022, Russia launched a large-scale invasion of Ukraine significantly amplifying already existing geopolitical tensions. The United States and many other countries have instituted various economic sanctions against Russia, Russian individuals and entities and Belarus. The extent and duration of the military action, sanctions imposed and other punitive actions taken (including any Russian retaliatory responses to such sanctions and actions), and resulting disruptions in Europe and

globally cannot be predicted, but could be significant and have a severe adverse effect on the global economy, securities markets and commodities markets globally, including through global supply chain disruptions, increased inflationary pressures and reduced economic activity. Ongoing conflicts in the Middle East could have similar negative impacts. To the extent the Fund has exposure to the energy sector, the Fund may be especially susceptible to these risks. Furthermore, in March 2023, the shut-down of certain financial institutions raised economic concerns over disruption in the U.S. banking system. There can be no certainty that the actions taken by the U.S. government to strengthen public confidence in the U.S. banking system will be effective in mitigating the effects of financial institution failures on the economy and restoring public confidence in the U.S. banking system. These disruptions may also make it difficult to value the Fund’s portfolio investments and cause certain of the Fund’s investments to become illiquid. The strengthening or weakening of the U.S. dollar relative to other currencies may, among other things, adversely affect the Fund’s investments denominated in non-U.S. dollar currencies. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have, and the duration of those effects.

Regulatory Risk: The U.S. government has proposed and adopted multiple regulations that could have a long-lasting impact on the Fund and on the mutual fund industry in general. The U.S. Securities and Exchange Commission (SEC) final rules, related requirements and amendments to modernize reporting and disclosure, along with other potential upcoming regulations, could, among other things, restrict the Fund’s ability to engage in transactions, impact flows into the Fund and/or increase overall expenses of the Fund. In addition to Rule 18f-4, which governs the way derivatives are used by registered investment companies, the SEC, Congress, various exchanges and regulatory and self-regulatory authorities, both domestic and foreign, have undertaken reviews of the use of derivatives by registered investment companies, which could affect the nature and extent of instruments used by the Fund. The Fund and the instruments in which it invests may be subject to new or additional regulatory constraints in the future. While the full extent of all of these regulations is still unclear, these regulations and actions may adversely affect both the Fund and the instruments in which the Fund invests and its ability to execute its investment strategy. For example, climate change regulation (such as decarbonization legislation, other mandatory controls to reduce emissions of greenhouse gases, or related disclosure requirements) could significantly affect the Fund or its investments by, among other things, increasing compliance costs or underlying companies’ operating costs and capital expenditures. Similarly, regulatory developments in other countries may have an unpredictable and adverse impact on the Fund.

Counterparty Risk: Weakening energy market fundamentals may increase counterparty risk and impact MLP profitability. Specifically, energy companies suffering financial distress may be able to abrogate contracts with MLPs, decreasing or eliminating sources of revenue.

Liquidity Risk: Although the equity securities, including those of the MLPs, in which the Fund invests generally trade on major stock exchanges, certain securities may trade less frequently, particularly those of MLPs and other issuers with smaller capitalizations. Securities with limited trading volumes may display volatile or erratic price movements. Also, the Fund may be one of the largest investors in certain sub-sectors of the energy or natural resource sectors. Thus, it may be more difficult for the Fund to buy and sell significant amounts of such securities without an unfavorable impact on

36

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS—(Continued)

prevailing market prices. Larger purchases or sales of these securities by the Fund in a short period of time may cause abnormal movements in the market price of these securities. As a result, these securities may be difficult to dispose of at a fair price at the times when the investment advisor believes it is desirable to do so.

Foreign (Non-U.S.) Securities Risk: The Fund directly purchases securities of foreign issuers. Risks of investing in foreign securities, which can be expected to be greater for investments in emerging markets, include currency risks, future political and economic developments and possible imposition of foreign withholding taxes on income or proceeds payable on the securities. In addition, there may be less publicly available information about a foreign issuer than about a domestic issuer, and foreign issuers may not be subject to the same accounting, auditing and financial recordkeeping standards and requirements as domestic issuers. Moreover, securities of many foreign issuers and their markets may be less liquid and their prices more volatile than securities of comparable U.S. issuers.

Non-Diversification Risk: As a “non-diversified” investment company, the Fund can invest in fewer individual companies than a diversified investment company. As a result, the Fund is more susceptible to any single political, regulatory or economic occurrence and to the financial condition of individual issuers in which it invests. The Fund’s relative lack of diversity may subject investors to greater risk of loss than a fund that has a diversified portfolio.

This is not a complete list of the risks of investing in the Fund. For additional information concerning the risks of investing in the Fund, please consult the Fund’s prospectus.

Note 8. Other

In the normal course of business, the Fund enters into contracts that provide general indemnifications. The Fund’s maximum exposure under these arrangements is dependent on claims that may be made against the Fund in the future and, therefore, cannot be estimated; however, based on experience, the risk of material loss from such claims is considered remote.

Note 9. Subsequent Events

Management has evaluated events and transactions occurring after November 30, 2023 through the date that the financial statements were issued, and, except as noted below, has determined that no additional disclosure in the financial statements is required.

Effective at the close of business on March 28, 2024, the Fund anticipates changing its name to the Cohen & Steers Future of Energy Fund, Inc. and making corresponding changes to the Fund’s principal investment strategies. Following these changes, the Fund’s performance benchmarks will be the S&P Energy Select Sector Index and a blended benchmark consisting of 70% S&P Energy Select Sector Index and 30% S&P North America and Europe Clean Energy Index.

As a result of these changes, effective at the close of business on March 28, 2024, under normal market conditions, the Fund will invest at least 80% of its net assets (plus borrowings for investment purposes) in equity securities of energy companies, including traditional-, alternative-, renewable-and clean-energy companies, natural resource companies, utilities, and companies in associated

37

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS—(Continued)

businesses (collectively, “Energy and Energy-Related Companies”). The Fund will seek to invest in Energy and Energy-Related Companies that the investment advisor believes are leading, enabling, supplying, disrupting, or otherwise benefiting from transitional or longer-term structural changes to the global energy sector, such as changes resulting from shifting demand and supply of traditional and alternative energy sources, increasing emphasis on storage, resilience, and security of supply, and other developments in technologies, regulations, and behaviors affecting the energy sector.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Cohen & Steers MLP & Energy Opportunity Fund, Inc.

Opinion on the Financial Statements

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of November 30, 2023, 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 ended November 30, 2023 and the financial highlights for each of the five years in the period ended November 30, 2023 in conformity with accounting principles generally accepted in the United States of America.

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 of these financial statements 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.

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 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. Our procedures included confirmation of securities owned as of November 30, 2023 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

TAX INFORMATION—2023

For the fiscal year ended November 30, 2023, for individual taxpayers, the Fund designates $3,347,160 as qualified dividend income eligible for reduced tax rates. In addition, for corporate taxpayers, 40.87% of the ordinary dividends paid qualified for the dividends received deduction (DRD).

OTHER INFORMATION

A description of the policies and procedures that the Fund uses to determine how to vote proxies relating to portfolio securities is available (i) without charge, upon request, by calling 800-330-7348, (ii) on our website at cohenandsteers.com or (iii) on the SEC’s website at http://www.sec.gov. In addition, the Fund’s proxy voting record for the most recent 12-month period ended June 30 is available by August 31 of each year (i) without charge, upon request, by calling 800-330-7348 or (ii) on the SEC’s website at http://www.sec.gov.

Disclosures of the Fund’s complete holdings are required to be made monthly on Form N-PORT, with every third month made available to the public by the SEC 60 days after the end of the Fund’s fiscal quarter. The Fund’s Form N-PORT is available (i) without charge, upon request, by calling 800-330-7348 or (ii) on the SEC’s website at http://www.sec.gov.

Please note that distributions paid by the Fund to shareholders are subject to recharacterization for tax purposes and are taxable up to the amount of the Fund’s investment company taxable income and net realized gains. Distributions in excess of the Fund’s net investment company taxable income and realized gains are a return of capital distributed from the Fund’s assets. The final tax treatment of all distributions is reported to shareholders on their 1099-DIV forms, which are mailed after the close of each calendar year. Distributions of capital decrease the Fund’s total assets and, therefore, could have the effect of increasing the Fund’s expense ratio. In addition, in order to make these distributions, the Fund may have to sell portfolio securities at a less than opportune time.

APPROVAL OF INVESTMENT ADVISORY AND SUBADVISORY AGREEMENTS

The Board of Directors of the Fund, including a majority of the directors who are not parties to the Fund’s investment advisory and subadvisory agreements (the Advisory Agreements), or interested persons of any such party (the Independent Directors), has the responsibility under the Investment Company Act of 1940 to approve the Fund’s Advisory Agreements for their initial two year terms and their continuation annually thereafter at a meeting of the Board of Directors called for the purpose of voting on the approval or continuation. The Advisory Agreements were discussed at a meeting of the Independent Directors, in their capacity as the Contract Review Committee, held on June 6, 2023 and at meetings of the full Board of Directors held on March 14, 2023 and June 13, 2023. The Independent Directors, in their capacity as the Contract Review Committee, also discussed the Advisory Agreements in executive session on June 13, 2023. At the meeting of the full Board of Directors on June 13, 2023, the Advisory Agreements were unanimously continued for a term ending June 30, 2024 by the Fund’s Board of Directors, including the Independent Directors. The Independent Directors were represented by independent counsel who assisted them in their deliberations during the meetings and executive session.

In considering whether to continue the Advisory Agreements, the Board of Directors reviewed materials provided by an independent data provider, which included, among other items, fee, expense

40

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

and performance information compared to peer funds (the Peer Funds and, collectively with the Fund, the Peer Group) and performance comparisons to a larger category universe; summary information prepared by the Fund’s investment advisor (the Investment Advisor); and a memorandum from counsel to the Independent Directors outlining the legal duties of the Board of Directors. The Board of Directors also spoke directly with representatives of the independent data provider and met with investment advisory personnel. In addition, the Board of Directors considered information provided from time to time by the Investment Advisor throughout the year at meetings of the Board of Directors, including presentations by portfolio managers relating to the investment performance of the Fund and the investment strategies used in pursuing the Fund’s objective. The Board of Directors also considered information provided by the Investment Advisor in response to a request for information submitted by counsel to the Independent Directors, on behalf of the Independent Directors, as well as information provided by the Investment Advisor in response to a supplemental request. In particular, the Board of Directors considered the following:

(i) The nature, extent and quality of services to be provided by the Investment Advisor and the Subadvisors: The Board of Directors reviewed the services that the Investment Advisor and the sub-investment advisors (the Subadvisors) provide to the Fund, including, but not limited to, making the day-to-day investment decisions for the Fund, placing orders for the investment and reinvestment of the Fund’s assets, furnishing information to the Board of Directors of the Fund regarding the Fund’s portfolio, providing individuals to serve as Fund officers, and for the Investment Advisor, generally managing the Fund’s investments in accordance with the stated policies of the Fund. The Board of Directors also discussed with officers and portfolio managers of the Fund the types of transactions conducted on behalf of the Fund. Additionally, the Board of Directors took into account the services provided by the Investment Advisor and the Subadvisors to other funds and accounts, including those that have investment objectives and strategies similar to those of the Fund. The Board of Directors also considered the education, background and experience of the Investment Advisor’s and Subadvisors’ personnel, particularly noting the potential benefit that the portfolio managers’ work experience and favorable reputation can have on the Fund. The Board of Directors further noted the Investment Advisor’s and Subadvisors’ ability to attract qualified and experienced personnel. The Board of Directors also considered the administrative services provided by the Investment Advisor, including compliance and accounting services. After consideration of the above factors, among others, the Board of Directors concluded that the nature, extent and quality of services provided by the Investment Advisor and the Subadvisors are satisfactory and appropriate.

(ii) Investment performance of the Fund and the Investment Advisor and the Subadvisors: The Board of Directors considered the investment performance of the Fund compared to Peer Funds and compared to a relevant linked blended benchmark. The Board of Directors noted that the Fund represented the Peer Group median for the one-and three-year periods ended March 31, 2023, ranking five out of nine peers for each period and that the Fund underperformed the peer group median for the five-year period ended March 31, 2023, ranking six out of nine peers. The Board of Directors noted that the Fund underperformed the linked blended benchmark for theone-, three-, and five-year periods ended March 31, 2023. The Board of Directors engaged in discussions with the Investment Advisor regarding the contributors to and detractors from the Fund’s performance during the period. The Board of Directors also considered supplemental information provided by the Investment Advisor, including a narrative summary of various factors affecting performance and the Investment Advisor’s performance in managing similarly managed funds and accounts. The Board of Directors determined that Fund

41

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

performance, in light of all the considerations noted above, supported the continuation of the Advisory Agreements.

(iii) Cost of the services to be provided and profits to be realized by the Investment Advisor from the relationship with the Fund: The Board of Directors considered the contractual and actual management fees paid by the Fund as well as the Fund’s total expense ratio. As part of its analysis, the Board of Directors gave consideration to the fee and expense analyses provided by the independent data provider. The Board of Directors noted that the Fund’s actual management fee and total expense ratio were the lowest in the Peer Group, ranking one out of nine peers for each. The Board of Directors considered that the Investment Advisor continues to waive a portion of its fees and/or reimburse expenses to limit the overall operating expenses of the Fund. In light of the considerations above, the Board of Directors concluded that the Fund’s expense structure was satisfactory.

The Board of Directors also reviewed information regarding the profitability to the Investment Advisor of its relationship with the Fund. The Board of Directors considered the level of the Investment Advisor’s profits and whether the profits were reasonable for the Investment Advisor. The Board of Directors noted that the Investment Advisor is currently waiving a portion of its fee and/or reimbursing expenses of the Fund. Since the Subadvisors are paid by the Investment Advisor (and not by the Fund) for investment services provided to the Fund and are affiliates of the Investment Advisor, the Board of Directors considered the profitability of the Investment Advisor as a whole and did not consider the Subadvisors’ separate profitability to be particularly relevant to their determination. The Board of Directors took into consideration other benefits to be derived by the Investment Advisor in connection with the Advisory Agreements, noting particularly the research and related services, within the meaning of Section 28(e) of the Securities Exchange Act of 1934, that the Investment Advisor receives by allocating the Fund’s brokerage transactions. The Board of Directors further considered that the Investment Advisor continues to reinvest profits back in the business, including upgrading and/or implementing new trading, compliance and accounting systems, and by adding investment personnel to the portfolio management teams. The Board of Directors also considered the administrative services provided by the Investment Advisor and the associated administration fee paid to the Investment Advisor for such services under the Administration Agreement. The Board of Directors determined that the services received under the Administration Agreement are beneficial to the Fund. The Board of Directors concluded that the profits realized by the Investment Advisor from its relationship with the Fund were reasonable and consistent with the Investment Advisor’s fiduciary duties.

(iv) The extent to which economies of scale would be realized as the Fund grows and whether fee levels would reflect such economies of scale: The Board of Directors considered the Fund’s asset size and determined that there were not at this time significant economies of scale that were not being shared with shareholders, concluding that the Fund’s expense structure was satisfactory. In considering economies of scale, the Board of Directors also noted, as discussed above in (iii), that the Investment Advisor continues to reinvest profits back in the business.

(v) Comparison of services to be rendered and fees to be paid to those under other investment advisory contracts, such as contracts of the same and other investment advisors or other clients: As discussed above in (iii), the Board of Directors compared the fees paid under the Advisory Agreements to those under other investment advisory contracts of other investment advisors managing Peer Funds. The Board of Directors also compared the services rendered and fees paid under the Advisory Agreements to fees paid, including the ranges of such fees, under the Investment Advisor’s other fund

42

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

advisory agreements and advisory contracts with institutional and other clients with similar investment mandates, noting that the Investment Advisor provides more services to the Fund than it does for institutional or subadvised accounts. The Board of Directors also considered the entrepreneurial risk and financial exposure assumed by the Investment Advisor in developing and managing the Fund that the Investment Advisor does not have with institutional and other clients and other differences in the management of registered investment companies and institutional accounts. The Board of Directors determined that on a comparative basis the fees under the Advisory Agreements were reasonable in relation to the services provided.

No single factor was cited as determinative to the decision of the Board of Directors, and each Director may have assigned different weights to the various factors. Rather, after weighing all of the considerations and conclusions discussed above, the Board of Directors, including the Independent Directors, unanimously approved the continuation of the Advisory Agreements.

LIQUIDITY RISK MANAGEMENT PROGRAM

Pursuant to Rule 22e-4 under the Investment Company Act of 1940 (the Liquidity Rule), the Fund has adopted and implemented a liquidity risk management program (the Program). The Liquidity Rule requires an open-end investment company to adopt a program that is reasonably designed to assess and manage its liquidity risk, which is the risk that an open-end investment company could not meet redemption requests without significant dilution of remaining investors’ interests in the open-end investment company. The Board has designated Cohen & Steers Capital Management, Inc. (the Investment Advisor) as the administrator of the Program. The Investment Advisor has delegated this responsibility to the Liquidity Risk Management Committee (the LRM Committee), which is comprised of representatives from various departments within the Investment Advisor. The Program includes policies and procedures reasonably designed to: (1) assess, manage, and periodically review the Fund’s liquidity risk; (2) classify the Fund’s portfolio investments as highly liquid, moderately liquid, less liquid, or illiquid; (3) determine a highly liquid investment minimum (HLIM) for the Fund or determine that one is not required; (4) limit the Fund’s illiquid investments to no more than 15% of its net assets; and (5) establish how and when the Fund will engage in in-kind redemptions.

The Board met on June 13, 2023 (the Meeting) to review the Program. At the Meeting, the LRM Committee provided the Board with a report that addressed the operation of the Program, including its implementation and effectiveness in assessing and managing the Fund’s liquidity risk (the Report). The Report covered the period from April 1, 2022 through March 31, 2023 (the Reporting Period).

The Report described the LRM Committee’s role in administering the Program, which complied with the Liquidity Rule requirements for assessing, managing and reviewing the Fund’s liquidity risk through the LRM Committee’s daily monitoring and quarterly analysis of liquidity parameters which include historical net redemption activity and consideration of the Fund’s shareholder ownership concentration, as applicable. The Report noted that the Fund’s investments are categorized into one of four liquidity buckets: highly liquid, moderately liquid, less liquid and illiquid. Liquidity classifications take into account a variety of market, trading, and investment factors, including the Fund’s reasonably anticipated trade size. The Investment Advisor has engaged a third-party vendor to assist with the classification of portfolio investments. The Report also described the LRM Committee’s determination that the Fund is a primarily highly liquid fund under the Liquidity Rule.

43

COHEN & STEERS MLP & ENERGY OPPORTUNITY FUND, INC.

The Report noted that there were no liquidity events during the Reporting Period that materially impacted the Fund’s ability to timely meet redemptions without significantly diluting remaining shareholders’ interests. The Report concluded that the Program is operating as intended, effective in implementing the requirements of the Liquidity Rule and reasonably designed to assess and manage the Fund’s liquidity risk.

There can be no assurance that the Program will achieve its objectives in the future. Please refer to the Fund’s prospectus for more information regarding the Fund’s exposure to liquidity risk and other principal risks to which an investment in the Fund may be subject.

MANAGEMENT OF THE FUND

The business and affairs of the Fund are managed under the direction of the Board of Directors.

The management of the Fund’s day-to-day operations is delegated to its officers, the investment advisor, administrator and co-administrator, subject always to the investment objective and policies of the Fund and to the general supervision of the Board of Directors.
