The performance data quoted represent past performance and cannot guarantee future results; current performance may be lower or higher. Investment return, net asset value (NAV) and common share market price will fluctuate so that you may have a gain or loss when you sell shares. Please visit invesco.com/us for the most recent month-end performance. Performance figures reflect Trust expenses, the reinvestment of distributions (if any) and changes in NAV for performance based on NAV and changes in market price for performance based on market price. Since the Trust is a closed-end management investment company, shares of the Trust may trade at a discount or premium from the NAV. This characteristic is separate and distinct from the risk that NAV could decrease as a result of investment activities and may be a greater risk to investors expecting to sell their shares after a short time. The Trust cannot predict whether shares will trade at, above or below NAV. The Trust should not be viewed as a vehicle for trading purposes. It is designed primarily for risk-tolerant long-term investors. The S&P Municipal Bond High Yield Index is an unmanaged index considered representative of municipal bonds that are not rated or are rated below investment-grade. The Custom Invesco Municipal Income Opportunities Trust Index is designed to measure the performance of a hypothetical allocation, which consists of 80% weight in the S&P Municipal Bond High Yield Index and 20% S&P Municipal Bond Investment Grade Index. The Trust is not managed to track the performance of any particular index, including the index(es) described here, and consequently, the performance of the Trust may deviate significantly from the performance of the index(es). A direct investment cannot be made in an index. Unless otherwise indicated, index results include reinvested dividends, and they do not reflect sales charges. Performance of the peer group, if applicable, reflects fund expenses; performance of a market index does not.

Important Notice Regarding Share Repurchase Program

In September 2025, the Board of Trustees of the Trust approved a share repurchase program that allows the Trust to repurchase up to 25% of the

20-day

average trading volume

of the Trust’s common shares when the Trust is trading at a 10% or greater discount to its net asset value. The Trust will repurchase

shares pursuant to this program if the Adviser reasonably believes that such repurchases may enhance shareholder value.

Dividend Reinvestment Plan

The dividend reinvestment plan (the Plan) offers you a prompt and simple way to reinvest your dividends and capital gains distributions (Distributions) into additional shares of your Invesco

closed-end

Trust (the Trust). Under the Plan, the money you earn from Distributions will be reinvested automatically in more shares of the Trust, allowing you to potentially increase your investment over time. All shareholders in the Trust are automatically enrolled in the Plan when shares are purchased.

Plan benefits

∎

Add to your account:

You may increase your shares in your Trust easily and automatically with the Plan.

∎

Low transaction costs:

Shareholders who participate in the Plan may be able to buy shares at below-market prices when the Trust is trading at a premium to its net asset value (NAV). In addition, transaction costs are low because when new shares are issued by the Trust, there is no brokerage fee, and when shares are bought in blocks on the open market, the per share fee is shared among all participants.

∎

Convenience:

You will receive a detailed account statement from Computershare Trust Company, N.A. (the Agent), which administers the Plan. The statement shows your total Distributions, date of investment, shares acquired, and price per share, as well as the total number of shares in your reinvestment account. You can also access your account at

invesco.com/closed-end.

∎

Safekeeping:

The Agent will hold the shares it has acquired for you in safekeeping.

Who can participate in the Plan

If you own shares in your own name, your purchase will automatically enroll you in the Plan. If your shares are held in “street name” – in the name of your brokerage firm, bank, or other financial institution – you must instruct that entity to participate on your behalf. If they are unable to participate on your behalf, you may request that they reregister your shares in your own name so that you may enroll in the Plan.

How to enroll

If you haven’t participated in the Plan in the past or chose to opt out, you are still eligible to participate. Enroll by visiting

invesco.com/closed-end,

by calling toll-free 800 341 2929 or by notifying us in writing at Invesco

Closed-End

Funds, Computershare Trust Company, N.A., P.O. Box 43078, Providence, RI 02940-3078. If you are writing to us, please include the Trust name and account number and ensure that all shareholders listed on the account sign these written instructions. Your participation in the Plan will begin with the next Distribution payable after the Agent receives your authorization, as long as they receive it before the “record date,” which is generally 10 business days before the Distribution is paid. If your authorization arrives after such record date, your participation in the Plan will begin with the following Distribution.

How the Plan works

If you choose to participate in the Plan, your Distributions will be promptly reinvested for you, automatically increasing your shares. If the Trust is trading at a share price that is equal to its NAV, you’ll pay that amount for your reinvested shares. However, if the Trust is trading above or below NAV, the price is determined by one of two ways:

Premium: If the Trust is trading at a premium – a market price that is higher than its NAV – you’ll pay either the NAV or 95 percent of

the market price, whichever is greater. When the Trust trades at a premium, you may pay less for your reinvested shares than an investor purchasing shares on the stock exchange. Keep in mind, a portion of your price reduction may be taxable because you are receiving shares at less than market price.

Discount: If the Trust is trading at a discount – a market price that is lower than its NAV – you’ll pay the market price for your reinvested shares.

Costs of the Plan

There is no direct charge to you for reinvesting Distributions because the Plan’s fees are paid by the Trust. If the Trust is trading at or above its NAV, your new shares are issued directly by the Trust and there are no brokerage charges or fees. However, if the Trust is trading at a discount, the shares are purchased on the open market, and you will pay your portion of any per share fees. These per share fees are typically less than the standard brokerage charges for individual transactions because shares are purchased for all participants in blocks, resulting in lower fees for each individual participant. Any service or per share fees are added to the purchase price. Per share fees include any applicable brokerage commissions the Agent is required to pay.

Tax implications

The automatic reinvestment of Distributions does not relieve you of any income tax that may be due on Distributions. You will receive tax information annually to help you prepare your federal income tax return.

Invesco does not offer tax advice. The tax information contained herein is general and is not exhaustive by nature. It was not intended or written to be used, and it cannot be used, by any taxpayer for avoiding penalties that may be imposed on the taxpayer under US federal tax laws. Federal and state tax laws are complex and constantly changing. Shareholders should always consult a legal or tax adviser for information concerning their individual situation.

How to withdraw from the Plan

You may withdraw from the Plan at any time by calling 800 341 2929, by visiting invesco.com/

closed-end

or by writing to Invesco

Closed-End

Funds, Computershare Trust Company, N.A., P.O. Box 43078, Providence, RI 02940-3078. Simply indicate that you would like to withdraw from the Plan, and be sure to include your Trust name and account number. Also, ensure that all shareholders listed on the account sign these written instructions. If you withdraw, you have three options with regard to the shares held in the Plan:

If you opt to continue to hold your

non-certificated

whole shares (Investment Plan Book Shares), they will be held by the Agent electronically as Direct Registration Book-Shares (Book-Entry Shares) and fractional shares will be sold at the then-current market price. Proceeds will be sent via check to your address of record after deducting applicable fees, including per share fees such as any applicable brokerage commissions the Agent is required to pay.

If you opt to sell your shares through the Agent, we will sell all full and fractional shares and send the proceeds via check to your address of record after deducting $2.50 per account and a brokerage charge.

You may sell your shares through your financial adviser through the Direct Registration System (DRS). DRS is a service within the securities industry that allows Trust shares to be held in your name in electronic format. You retain full ownership of your shares, without having to hold a share certificate. You should contact your financial adviser to learn more about any restrictions or fees that may apply.

The Trust and Computershare Trust Company, N.A. may amend or terminate the Plan at any time. Participants will receive at least 30 days written notice before the effective date of any amendment. In the case of termination, Participants will receive at least 30 days written notice before the record date for the payment of any such Distributions by the Trust. In the case of amendment or termination necessary or appropriate to comply with applicable law or the rules and policies of the Securities and Exchange Commission or any other regulatory authority, such written notice will not be required.

Notes to Schedule of Investments:

(a)	Calculated as a percentage of net assets. Amounts in excess of 100% are due to the Trust’s use of leverage.

(b)	Defaulted security. Currently, the issuer is in default with respect to principal and/or interest payments. The aggregate value of these securities at August 31, 2025 was $4,903,906, which represented 1.76% of the Trust’s Net Assets.

(c)	Restricted security. The aggregate value of these securities at August 31, 2025 was $5,000,651, which represented 1.79% of the Trust’s Net Assets.

(d)

Security purchased or received in a transaction exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). The security may be resold pursuant to an exemption from registration under the 1933 Act, typically to qualified institutional buyers. The aggregate value of these securities at August 31, 2025 was $68,878,833, which represented 24.72% of the Trust’s Net Assets.

(e)	Security subject to the alternative minimum tax.

(f)	Underlying security related to TOB Trusts entered into by the Trust. See Note 1K.

(g)	Principal and/or interest payments are secured by the bond insurance company listed.

(h)	Zero coupon bond issued at a discount.

(i)

Security is subject to a reimbursement agreement which may require the Trust to pay amounts to a counterparty in the event of a significant decline in the market value of the security underlying the TOB Trusts. In case of a shortfall, the maximum potential amount of payments the Trust could ultimately be required to make under the agreement is $45,161,280. However, such shortfall payment would be reduced by the proceeds from the sale of the security underlying the TOB Trusts.

(j)	Convertible capital appreciation bond. The interest rate shown represents the coupon rate at which the bond will accrue at a specified future date.

(k)	Security has an irrevocable call by the issuer or mandatory put by the holder. Maturity date reflects such call or put.

(l)	Advance refunded; secured by an escrow fund of U.S. Government obligations or other highly rated collateral.

(m)	Security valued using significant unobservable inputs (Level 3). See Note 3.

(n)	Entities may either issue, guarantee, back or otherwise enhance the credit quality of a security. The entities are not primarily responsible for the issuer’s obligations but may be called upon to satisfy the issuer’s obligations. No concentration of any single entity was greater than 5% each.

(o)

Floating rate note obligations related to securities held. The interest and fee rates shown reflect the rates in effect at August 31, 2025. At August 31, 2025, the Trust’s investments with a value of $173,670,023 are held by TOB Trusts and serve as collateral for the $130,780,000 in the floating rate note obligations outstanding at that date.

Notes to Financial Statements

August 31, 2025

(Unaudited)

NOTE 1–Significant Accounting Policies

Invesco Municipal Income Opportunities Trust (the “Trust”) is a Delaware statutory trust registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a

closed-end

management investment company.

The Trust’s investment objective is to provide a high level of current income which is exempt from federal income tax.

The Trust is an investment company and accordingly follows the investment company accounting and reporting guidance in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946,

Financial Services -

Investment Companies.

The following is a summary of the significant accounting policies followed by the Trust in the preparation of its financial statements.

A.	Security Valuations - Securities, including restricted securities, are valued according to the following policy.

Securities generally are valued on the basis of prices provided by independent pricing services. Prices provided by the pricing service may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as

institution-size

trading in similar groups of securities, developments related to specific securities, dividend rate (for unlisted equities), yield (for debt obligations), quality, type of issue, coupon rate (for debt obligations), maturity (for debt obligations), individual trading characteristics and other market data. Pricing services generally value debt obligations assuming orderly transactions of institutional round lot size, but a trust may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots, and their value may be adjusted accordingly. Debt obligations are subject to interest rate and credit risks. In addition, all debt obligations involve some risk of default with respect to interest and/or principal payments.

Securities for which market quotations are not readily available are fair valued by Invesco Advisers, Inc. (the “Adviser” or “Invesco”) in accordance with Board-approved policies and related Adviser procedures (“Valuation Procedures”). If a fair value price provided by a pricing service is not representative of market value in the Adviser’s judgment (“unreliable”), the Adviser will fair value the security using the Valuation Procedures. Issuer specific events, market trends, bid/ask quotes of brokers and information providers and other market data may be reviewed in the course of making a good faith determination of a security’s fair value.

The Trust may invest in securities that are subject to interest rate risk, meaning the risk that the prices will generally fall as interest rates rise and, conversely, the prices will generally rise as interest rates fall. Specific securities differ in their sensitivity to changes in interest rates depending on their individual characteristics. Changes in interest rates may result in increased market volatility, which may affect the value and/or liquidity of certain Trust investments.

Valuations change in response to many factors including the historical and prospective earnings of the issuer, the value of the issuer’s assets, general market conditions which are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, military conflicts, acts of terrorism, economic crises, economic sanctions and tariffs, significant governmental actions or adverse investor sentiment generally and market liquidity. Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

The price the Trust could receive upon the sale of any investment may differ from the Adviser’s valuation of the investment, particularly for securities that are valued using a fair valuation technique. When fair valuation techniques are applied, the Adviser uses available information, including both observable and unobservable inputs and assumptions, to determine a methodology that will result in a valuation that the Adviser believes approximates market value. Trust securities that are fair valued may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. Because of the inherent uncertainties of valuation, and the degree of subjectivity in such decisions, the Trust could realize a greater or lesser than expected gain or loss upon the sale of the investment.

Securities Transactions and Investment Income

- Securities transactions are accounted for on a trade date basis. Realized gains or losses on sales are computed on the basis of specific identification of the securities sold. Interest income (net of withholding tax, if any) is recorded on an accrual basis from settlement date and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

Pay-in-kind

interest income and

non-cash

dividend income received in the form of securities in lieu of cash are recorded at the fair value of the securities received. Dividend income (net of withholding tax, if any) is recorded on the

ex-dividend

date.

The Trust may periodically participate in litigation related to Trust investments. As such, the Trust may receive proceeds from litigation settlements. Any proceeds received are included in the Statement of Operations as realized gain (loss) for investments no longer held and as unrealized gain (loss) for investments still held.

Brokerage commissions and mark ups are considered transaction costs and are recorded as an increase to the cost basis of securities purchased and/or a reduction of proceeds on a sale of securities. Such transaction costs are included in the determination of net realized and unrealized gain (loss) from investment securities reported in the Statement of Operations and the Statement of Changes in Net Assets and the net realized and unrealized gains (losses) on securities per share in the Financial Highlights. Transaction costs are included in the calculation of the Trust’s net asset value and, accordingly, they reduce the Trust’s total returns. These transaction costs are not considered operating expenses and are not reflected in net investment income reported in the Statement of Operations and the Statement of Changes in Net Assets, or the net investment income per share and the ratios of expenses and net investment income reported in the Financial Highlights, nor are they limited by any expense limitation arrangements between the Trust and the investment adviser.

Country Determination

- For the purposes of making investment selection decisions and presentation in the Schedule of Investments, the investment adviser may determine the country in which an issuer is located and/or credit risk exposure based on various factors. These factors include the laws of the country under which the issuer is organized, where the issuer maintains a principal office, the country in which the issuer derives 50% or more of its total revenues, the country that has the primary market for the issuer’s securities and its “country of risk” as determined by a third party service provider, as well as other criteria. Among the other criteria that may be evaluated for making this determination are the country in which the issuer maintains 50% or more of its assets, the type of security, financial guarantees and enhancements, the nature of the collateral and the sponsor organization. Country of issuer and/or credit risk exposure has been determined to be the United States of America, unless otherwise noted.

D.	Distributions - The Trust declares and pays monthly dividends from net investment income to common shareholders. Distributions from net realized capital gain, if any, are generally declared and paid annually and are distributed on a pro rata basis to common and preferred shareholders.

Federal Income Taxes -

The Trust intends to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), necessary to qualify as a regulated investment company and to distribute substantially all of the Trust’s taxable earnings to shareholders. As such, the Trust will not be subject to federal income taxes on otherwise taxable income (including net realized capital gain) that is distributed to shareholders. Therefore, no provision for federal income taxes is recorded in the financial statements.

The Trust recognizes the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained. Management has analyzed the Trust’s uncertain tax positions and concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions. Management is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

In addition, the Trust intends to invest in such municipal securities to allow it to qualify to pay shareholders “exempt dividends”, as defined in the Internal Revenue Code.


17		Invesco Municipal Income Opportunities Trust

The Trust files tax returns in the U.S. Federal jurisdiction and certain other jurisdictions. Generally, the Trust is subject to examinations by such taxing authorities for up to three years after the filing of the return for the tax period.

Interest, Facilities and Maintenance Fees

- Interest, Facilities and Maintenance Fees include interest and related borrowing costs such as commitment fees, rating and bank agent fees, administrative expenses and other expenses associated with establishing and maintaining the line of credit and Variable Rate Muni Term Preferred Shares (“VMTP Shares”). In addition, interest and administrative expenses related to establishing and maintaining floating rate note obligations, if any, are included.

Accounting Estimates

- The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“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 revenues and expenses during the reporting period including estimates and assumptions related to taxation. Actual results could differ from those estimates by a significant amount. In addition, the Trust monitors for material events or transactions that may occur or become known after the

period-end

date and before the date the financial statements are released to print.

Indemnifications

- Under the Trust’s organizational documents, each Trustee, officer, employee or other agent of the Trust is indemnified against certain liabilities that may arise out of the performance of their duties to the Trust. Additionally, in the normal course of business, the Trust enters into contracts, including the Trust’s servicing agreements, that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred. The risk of material loss as a result of such indemnification claims is considered remote.

Segment Reporting

- The Trust represents a single operating segment, in accordance with ASC 280, Segment Reporting. Subject to the oversight and, when applicable, approval of the Board of Trustees, the Adviser acts as the Trust’s chief operating decision maker (“CODM”), assessing performance and making decisions about resource allocation within the Trust. The CODM monitors the operating results as a whole, and the Trust’s long-term strategic asset allocation is determined in accordance with the terms of its prospectus based on a defined investment strategy. The financial information provided to and reviewed by the CODM is consistent with that presented in the Trust’s financial statements.

J.	Cash and Cash Equivalents - For the purposes of the Statement of Cash Flows, the Trust defines Cash and Cash Equivalents as cash (including foreign currency), restricted cash, money market funds and other investments held in lieu of cash and excludes investments made with cash collateral received.

Floating Rate Note Obligations

- The Trust invests in inverse floating rate securities, such as Tender Option Bonds (“TOBs”), for investment purposes and to enhance the yield of the Trust. Such securities may be purchased in the secondary market without first owning an underlying bond but generally are created through the sale of fixed rate bonds by the Trust to special purpose trusts established by a broker dealer or by the Trust (“TOB Trusts”) in exchange for cash and residual interests in the TOB Trusts’ assets and cash flows, which are in the form of inverse floating rate securities. The TOB Trusts finance the purchases of the fixed rate bonds by issuing floating rate notes to third parties and allowing the Trust to retain residual interests in the bonds. The floating rate notes issued by the TOB Trusts have interest rates that reset weekly and the floating rate note holders have the option to tender their notes to the TOB Trusts for redemption at par at each reset date. The residual interests held by the Trust (inverse floating rate securities) include the right of the Trust (1) to cause the holders of the floating rate notes to tender their notes at par at the next interest rate reset date, and (2) to transfer the municipal bond from the TOB Trust to the Trust, thereby collapsing the TOB Trust. Inverse floating rate securities tend to underperform the market for fixed rate bonds in a rising interest rate environment, but tend to outperform the market for fixed rate bonds when interest rates decline or remain relatively stable.

The Trust generally invests in inverse floating rate securities that include embedded leverage, thus exposing the Trust to greater risks and increased costs. The primary risks associated with inverse floating rate securities are varying degrees of liquidity and decreases in the value of such securities in response to changes in interest rates to a greater extent than fixed rate securities having similar credit quality, redemption provisions and maturity, which may cause the Trust’s net asset value to be more volatile than if it had not invested in inverse floating rate securities. In certain instances, the short-term floating rate notes created by the TOB Trust may not be able to be sold to third parties or, in the case of holders tendering (or putting) such notes for repayment of principal, may not be able to be remarketed to third parties. In such cases, the TOB Trust holding the fixed rate bonds may be collapsed with the entity that contributed the fixed rate bonds to the TOB Trust. In the case where a TOB Trust is collapsed with the Trust, the Trust will be required to repay the principal amount of the tendered securities, which may require the Trust to sell other portfolio holdings to raise cash to meet that obligation. The Trust could therefore be required to sell other portfolio holdings at a disadvantageous time or price to raise cash to meet this obligation, which risk will be heightened during times of market volatility, illiquidity or uncertainty. The embedded leverage in the TOB Trust could cause the Trust to lose more money than the value of the asset it has contributed to the TOB Trust and greater levels of leverage create the potential for greater losses. In addition, a Trust may enter into reimbursement agreements with the liquidity provider of certain TOB transactions in connection with certain residuals held by the Trust. These agreements commit a Trust to reimburse the liquidity provider to the extent that the liquidity provider must provide cash to a TOB Trust, including following the termination of a TOB Trust resulting from a mandatory tender event (“liquidity shortfall”). The reimbursement agreement will effectively make the Trust liable for the amount of the negative difference, if any, between the liquidation value of the underlying security and the purchase price of the floating rate notes issued by the TOB Trust.

The Trust accounts for the transfer of fixed rate bonds to the TOB Trusts as secured borrowings, with the securities transferred remaining in the Trust’s investment assets, and the related floating rate notes reflected as Trust liabilities under the caption

Floating rate note obligations

on the Statement of Assets and Liabilities. The carrying amount of the Trust’s floating rate note obligations as reported on the Statement of Assets and Liabilities approximates its fair value. The Trust records the interest income from the fixed rate bonds under the caption Interest and records the expenses related to floating rate obligations and any administrative expenses of the TOB Trusts as a component of

Interest, facilities and maintenance fees

on the Statement of Operations.

Final rules implementing section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Volcker Rule”) prohibit banking entities and their affiliates from sponsoring and/or providing certain services for existing TOB Trusts, which constitute “covered funds” under the Volcker Rule. As a result of the Volcker Rule, the Trust, as holder of inverse floating rate securities, is required to perform certain duties in connection with TOB financing transactions previously performed by banking entities. These duties may alternatively be performed by a

non-bank

third-party service provider. The Trust’s expanded role may increase its operational and regulatory risk.

Further, the SEC and various banking agencies have adopted rules implementing credit risk retention requirements for asset-backed securities (the “Risk Retention Rules”), which apply to TOB financing transactions and TOB Trusts. The Risk Retention Rules require the sponsor of a TOB Trust to retain at least 5% of the credit risk of the underlying security held by the TOB Trust. The Trust has adopted policies intended to comply with the Risk Retention Rules. The Risk Retention Rules may adversely affect the Trust’s ability to engage in TOB financing transactions or increase the costs of such transactions in certain circumstances.

There can be no assurances that TOB financing transactions will continue to be a viable or cost-effective form of leverage. The unavailability of TOB financing transactions or an increase in the cost of financing provided by TOB transactions may adversely affect the Trust’s net asset value, distribution rate and ability to achieve its investment objective.

TOBs are presently classified as private placement securities. Private placement securities are subject to restrictions on resale because they have not been registered under the Securities Act of 1933, as amended (the “1933 Act”), or are otherwise not readily marketable. As a result of the absence of a public trading market for these securities, they may be less liquid than publicly traded securities. Although atypical, these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by the Trust or less than what may be considered the fair value of such securities.

Other Risks

- The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s


18		Invesco Municipal Income Opportunities Trust

value, interest payments, repayment of principal and the Trust’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

There is a possibility that the credit rating of a municipal security may be downgraded after purchase, which may occur quickly and without advanced warning following sudden market downturns or unexpected developments involving an issuer, and which may adversely affect the liquidity and value of the security.

Fluctuations in the federal funds and equivalent foreign rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility, perhaps suddenly and to a significant degree, and to reduced liquidity for certain fixed income investments, particularly those with longer maturities. Such changes and resulting increased volatility may adversely impact the Trust, including its operations, universe of potential investment options, and return potential. It is difficult to predict the impact of interest rate changes on various markets. In addition, decreases in fixed income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed income markets. As a result, the value of the Trust’s investments and share price may decline. Changes in central bank policies and other governmental actions and political events within the U.S. and abroad may also, among other things, affect investor and consumer expectations and confidence in the financial markets. This could result in higher than normal redemptions by shareholders, which could potentially increase the Trust’s portfolio turnover rate and transaction costs.

The municipal issuers in which the Trust invests may be located in the same geographic area or may pay their interest obligations from revenue of similar projects, such as hospitals, airports, utility systems and housing finance agencies. This may make the Trust’s investments more susceptible to similar social, economic, political or regulatory occurrences, making the Trust more susceptible to experience a drop in its share price than if the Trust had been more diversified across issuers that did not have similar characteristics.

NOTE 2–Advisory Fees and Other Fees Paid to Affiliates

The Trust has entered into a master investment advisory agreement with the Adviser. Under the terms of the investment advisory agreement, the Trust accrues daily and pays monthly an advisory fee to the Adviser based on the annual rate of 0.55% of the Trust’s average weekly managed assets. Managed assets for this purpose means the Trust’s net assets, plus assets attributable to any outstanding preferred shares and the amount of any borrowings incurred for the purpose of leverage (whether or not such borrowed amounts are reflected in the Trust’s financial statements for purposes of GAAP).

Under the terms of a master

sub-advisory

agreement between the Adviser and each of Invesco Asset Management Limited, Invesco Asset Management (Japan) Limited, Invesco Hong Kong Limited, Invesco Management S.A., Invesco Senior Secured Management, Inc. and Invesco Canada Ltd. (collectively, the “Affiliated

Sub-Advisers”)

the Adviser, not the Trust, will pay 40% of the fees paid to the Adviser to any such Affiliated

Sub-Adviser(s)

that provide(s) discretionary investment management services to the Trust based on the percentage of assets allocated to such Affiliated

Sub-Adviser(s).

The Trust has entered into a master administrative services agreement with Invesco pursuant to which the Trust has agreed to pay Invesco for certain administrative costs incurred in providing accounting services to the Trust. For the six months ended August 31, 2025, expenses incurred under this agreement are shown in the Statement of Operations as Administrative services fees. Invesco has entered into a

sub-administration

agreement whereby State Street Bank and Trust Company (“SSB”) serves as fund accountant and provides certain administrative services to the Trust. Pursuant to a custody agreement with the Trust, SSB also serves as the Trust’s custodian.

Certain officers and trustees of the Trust are officers and directors of Invesco.

NOTE 3–Additional Valuation Information

GAAP defines fair value as the price 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, under current market conditions. GAAP establishes a hierarchy that prioritizes the inputs to valuation methods, giving the highest priority to readily available unadjusted quoted prices in an active market for identical assets (Level 1) and the lowest priority to significant unobservable inputs (Level 3), generally when market prices are not readily available. Based on the valuation inputs, the securities or other investments are tiered into one of three levels. Changes in valuation methods may result in transfers in or out of an investment’s assigned level:


Level 1 -		Prices are determined using quoted prices in an active market for identical assets.
Level 2 -		Prices are determined using other significant observable inputs. Observable inputs are inputs that other market participants may use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, yield curves, loss severities, default rates, discount rates, volatilities and others. When market movements occur after the close of the relevant foreign securities markets, foreign securities may be fair valued utilizing an independent pricing service.
Level 3 -		Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect the Adviser’s assumptions about the factors market participants would use in determining fair value of the securities or instruments and would be based on the best available information.

The following is a summary of the tiered valuation input levels, as of August 31, 2025. The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities. Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

NOTE 4–Security Transactions with Affiliated Funds

The Trust is permitted to purchase securities from or sell securities to certain other affiliated funds under specified conditions outlined in procedures adopted by the Board of Trustees of the Trust. The procedures have been designed to ensure that any purchase or sale of securities by the Trust from or to another fund that is or could be considered an “affiliated person” by virtue of having a common investment adviser (or affiliated investment advisers), common Trustees and/or common


19		Invesco Municipal Income Opportunities Trust

officers is made in reliance on Rule

17a-7

of the 1940 Act and, to the extent applicable, related SEC staff positions. Each such transaction is effected at the security’s “current market price”, as provided for in these procedures and Rule

17a-7.

Pursuant to these procedures, for the six months ended August 31, 2025, the Trust engaged in securities purchases of $35,523,852 and securities sales of $23,916,032, which resulted in net realized gains (losses) of $(741,927).

NOTE 5–Trustees’ and Officers’ Fees and Benefits

Trustees’ and Officers’ Fees and Benefits

include amounts accrued by the Trust to pay remuneration to certain Trustees and Officers of the Trust. Trustees have the option to defer compensation payable by the Trust, and

Trustees’ and Officers’ Fees and Benefits

also include amounts accrued by the Trust to fund such deferred compensation amounts. Those Trustees who defer compensation have the option to select various Invesco Trusts in which their deferral accounts shall be deemed to be invested. Finally, certain current Trustees were eligible to participate in a retirement plan that provided for benefits to be paid upon retirement to Trustees over a period of time based on the number of years of service. The Trust may have certain former Trustees who also participate in a retirement plan and receive benefits under such plan.

Trustees’ and Officers’ Fees and Benefits

include amounts accrued by the Trust to fund such retirement benefits. Obligations under the deferred compensation and retirement plans represent unsecured claims against the general assets of the Trust.

NOTE 6–Cash Balances and Borrowings

The Trust is permitted to temporarily carry a negative or overdrawn balance in its account with SSB, the custodian bank. Such balances, if any at

period-end,

are shown in the Statement of Assets and Liabilities under the payable caption

Amount due custodian

. To compensate the custodian bank for such overdrafts, the overdrawn Trust may either (1) leave funds as a compensating balance in the account so the custodian bank can be compensated by earning the additional interest; or (2) compensate by paying the custodian bank at a rate agreed upon by the custodian bank and Invesco, not to exceed the contractually agreed upon rate.

Inverse floating rate obligations resulting from the transfer of bonds to TOB Trusts are accounted for as secured borrowings. The average floating rate notes outstanding and average annual interest and fee rate related to inverse floating rate note obligations during the six months ended August 31, 2025 were $123,360,714 and 3.76%, respectively.

NOTE 7–Tax Information

The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from GAAP.

Reclassifications are made to the Trust’s capital accounts to reflect income and gains available for distribution (or available capital loss carryforward) under income tax regulations. The tax character of distributions paid during the year and the tax components of net assets will be reported at the Trust’s fiscal

year-end.

Capital loss carryforward is calculated and reported as of a specific date. Results of transactions and other activity after that date may affect the amount of capital loss carryforward actually available for the Trust to utilize. The ability to utilize capital loss carryforward in the future may be limited under the Internal Revenue Code and related regulations based on the results of future transactions.

The Trust had a capital loss carryforward as of February 28, 2025, as follows:


Capital Loss Carryforward*


Expiration	Short-Term		Long-Term		Total


Not subject to expiration	$	11,855,844	$	27,434,936	$	39,290,780

*	Capital loss carryforward is reduced for limitations, if any, to the extent required by the Internal Revenue Code and may be further limited depending upon a variety of factors, including the realization of net unrealized gains or losses as of the date of any reorganization.

NOTE 8–Investment Transactions

The aggregate amount of investment securities (other than short-term securities, U.S. Government obligations and money market funds, if any) purchased and sold by the Trust during the six months ended August 31, 2025 was $66,505,720 and $54,494,249, respectively. As of August 31, 2025, the aggregate cost of investments, including any derivatives, on a tax basis listed below includes the adjustments for financial reporting purposes as of the most recently completed federal income tax reporting

period-end:


Unrealized Appreciation (Depreciation) of Investments on a Tax Basis


Aggregate unrealized appreciation of investments	$	12,077,139


Aggregate unrealized (depreciation) of investments		(31,744,131	)


Net unrealized appreciation (depreciation) of investments	$	(19,666,992	)

Cost of investments for tax purposes is $431,311,621.

NOTE 9–Common Shares of Beneficial Interest

Transactions in common shares of beneficial interest were as follows:


	Six Months Ended		Year Ended
	August 31,		February 28,
	2025		2025
Beginning shares		47,676,824		47,644,344
Shares issued through dividend reinvestment		–		32,480
Ending shares		47,676,824		47,676,824

The Trust may, when appropriate, purchase shares in the open market or in privately negotiated transactions at a price not above market value or net asset value, whichever is lower at the time of purchase.

The Trust has filed a registration statement (the “Registration Statement”) with the U.S. Securities and Exchange Commission authorizing the Trust to issue up to 25,500,000 additional common shares through a “shelf” registration process pursuant to Rule 415 under the 1933 Act.

During the six months ended August 31, 2025 and the year ended February 28, 2025, the Trust did not sell any common shares pursuant to the Registration Statement.

The Trust has entered into a distribution agreement with Invesco Distributors, Inc. (“IDI”), an affiliate of the Trust and Invesco, to provide for distribution of the Trust’s common shares. IDI has entered into a

sub-placement

agent agreement dated March 13, 2025 with JonesTrading Institutional Services LLC pursuant to which


20		Invesco Municipal Income Opportunities Trust

JonesTrading Institutional Services LLC will be acting as IDI’s exclusive

sub-placement

agent (the

“Sub-Placement

Agent”) with respect to the Trust’s common shares offered pursuant to the Registration Statement.

Under the 1940 Act, the Trust may not sell any common shares at a price below the current net asset value per share of such common shares plus the per share amount of any distributing commission or discount. The Trust or IDI will suspend the sale of common shares if the per share price of the common shares is less than such minimum price. The Trust currently intends to distribute the common shares offered pursuant to the Registration Statement primarily in negotiated transactions or through transactions deemed “at the market,” as defined in Rule 415 under the 1933 Act, including sales made directly on the NYSE or sales made to or through a market maker other than on an exchange at prices related to the prevailing market prices or at negotiated prices.

The Trust will compensate IDI with respect to sales of common shares at a commission rate of up to 1.00% of the gross proceeds of the sale of the Trust’s common shares. Out of this amount, IDI will compensate the

Sub-Placement

Agent at a rate of up to the full 1.00% of the gross sales proceeds of the sale of the Trust’s common shares sold by the

Sub-Placement

Agent.

21		Invesco Municipal Income Opportunities Trust

Approval of Investment Advisory and Sub-Advisory Contracts

At meetings held on June 16, 2025, the Board of Trustees (the Board or the Trustees) of Invesco Municipal Income Opportunities Trust (the Fund) as a whole, and the independent Trustees, who comprise over 75% of the Board, voting separately, approved the continuance of the Fund’s Master Investment Advisory Agreement with Invesco Advisers, Inc. (Invesco Advisers and the investment advisory agreement) and the Master Intergroup

Sub-Advisory

Contract for Mutual Funds with Invesco Asset Management Deutschland GmbH*, Invesco Asset Management Limited, Invesco Asset Management (Japan) Limited, Invesco Hong Kong Limited, Invesco Senior Secured Management, Inc. and Invesco Canada Ltd. (collectively, the Affiliated

Sub-Advisers

and the

sub-advisory

contracts) for another year, effective July 1, 2025. After evaluating the factors discussed below, among others, the Board approved the renewal of the Fund’s investment advisory agreement and the

sub-advisory

contracts and determined that the compensation payable thereunder by the Fund to Invesco Advisers and by Invesco Advisers to the Affiliated

Sub-Advisers

is fair and reasonable.

The Board’s Evaluation Process

The Board has established an Investments Committee, which in turn has established

Sub-Committees.

The

Sub-Committees

meet regularly throughout the year with portfolio managers and other members of management to review information about the investment performance and portfolio attributes for those funds advised by Invesco Advisers (Invesco Funds) assigned to them. The Board has established additional standing and ad hoc committees that meet throughout the year to review matters within their purview, including a working group focused on opportunities to make ongoing and continuous improvements to the Board’s annual review process for the Invesco Funds’ investment advisory agreement and

sub-advisory

contracts (the annual review process). In considering whether to approve each Invesco Fund’s investment advisory agreement and

sub-advisory

contracts, the Board took into account evaluations and reports that it received from its committees and

sub-committees,

as well as the information provided to the Board and its committees and

sub-committees

throughout the year.

As part of the annual review process, the Board reviews and considers information provided in response to requests for information submitted to management by the independent Trustees with assistance from legal counsel to the independent Trustees (independent legal counsel) and the Senior Officer, an officer of the Invesco Funds who reports directly to the independent Trustees. The Board receives comparative investment performance and fee and expense data regarding the Invesco Funds prepared by Broadridge Financial Solutions, Inc. (Broadridge), an independent provider of investment company data, as well as information on the composition of the peer groups and its methodology for determining peer groups. The Board also receives an independent written evaluation from the Senior Officer. The Senior Officer’s evaluation is prepared as part of his responsibility to manage the process by which the Invesco Funds’ proposed management fees are negotiated during the annual review process to

ensure they are negotiated in a manner that is at arms’ length and reasonable in accordance with certain negotiated regulatory requirements. In addition to meetings with Invesco Advisers and fund counsel throughout the year and as part of meetings convened on May 6, 2025 and June

16-18,

2025, the independent Trustees also discussed the continuance of the investment advisory agreement and

sub-advisory

contracts in separate sessions with the Senior Officer and with independent legal counsel.

The discussion below includes summary information drawn in part from the Senior Officer’s independent written evaluation with respect to the Fund’s investment advisory agreement and

sub-advisory

contracts, as well as a discussion of the material factors and related conclusions that formed the basis for the Board’s approval of the Fund’s investment advisory agreement and

sub-advisory

contracts. The Trustees’ review and conclusions are based on the comprehensive consideration of all information presented to them during the course of the year and are not the result of any single determinative factor. Moreover, one Trustee may have weighed a particular piece of information or factor differently than another Trustee.

Factors and Conclusions and Summary of Independent Written Fee Evaluation

A.	Nature, Extent and Quality of Services Provided by Invesco Advisers and the Affiliated Sub-Advisers

The Board reviewed the nature, extent and quality of the advisory services provided to the Fund by Invesco Advisers under the Fund’s investment advisory agreement, and the credentials and experience of the officers and employees of Invesco Advisers who provide these services, including the Fund’s portfolio manager(s). The Board’s review included consideration of Invesco Advisers’ investment process and oversight, credit analysis and research capabilities. The Board considered information regarding Invesco Advisers’ programs for and resources devoted to risk management, including management of investment, enterprise, operational, liquidity, derivatives, valuation and compliance risks, and technology used to manage such risks. The Board received information regarding Invesco’s methodology for compensating its investment professionals and the incentives and accountability it creates, as well as how it impacts Invesco’s ability to attract and retain talent. The Board considered that Invesco Advisers has shown the willingness to commit resources to support investment in the business and to remain well-positioned to serve Fund shareholders including with regard to attracting and retaining qualified personnel on its investment teams and investing in technology. The Board considered the additional services provided to the Fund due to the fact that the Fund is a

closed-end

fund, including, but not limited to, leverage management and monitoring, evaluating, and, where appropriate, making recommendations with respect to the Fund’s trading discount, share repurchase program, and distribution rates, as well as shareholder relations activities including with respect to investors focused on short-term profits. The Board also considered that Invesco had recommended, and the Board had approved, the filing of a “universal” shelf registration

statement for the Fund to register an offering of additional common shares of beneficial interest and subscription rights to purchase common shares, and had considered the benefits to the Fund and its shareholders of conducting a secondary offering pursuant to such registration statement. The Board received a description of, and reports related to, Invesco Advisers’ global security program and business continuity plans and of its approach to data privacy and cybersecurity, including related testing. The Board also considered

non-advisory

services that Invesco Advisers and its affiliates provide to the Invesco Funds, such as various middle office and back office support functions, third party oversight, internal audit, valuation, portfolio trading and legal and compliance. The Board considered Invesco Advisers’ systems preparedness and ongoing investment to seek to manage, operate and oversee the Invesco Funds with minimal impact or disruption through challenging environments. The Board reviewed and considered the benefits to shareholders of investing in a Fund that is part of the family of funds under the umbrella of Invesco Ltd., Invesco Advisers’ parent company, and noted Invesco Ltd.’s depth and experience in running an investment management business, as well as its commitment of financial and other resources to such business. The Board concluded that the nature, extent and quality of the services provided to the Fund by Invesco Advisers supported the renewal of the investment advisory agreement.

The Board reviewed the services that may be provided to the Fund by the Affiliated

Sub-Advisers

under the

sub-advisory

contracts and the credentials and experience of the officers and employees of the Affiliated

Sub-Advisers

who provide these services. The Board noted the Affiliated

Sub-Advisers’

expertise with respect to certain asset classes and that the Affiliated

Sub-Advisers

have offices and personnel that are located in financial centers around the world. As a result, the Board noted that the Affiliated

Sub-Advisers

can provide research and investment analysis on the markets and economies of various countries and territories in which the Fund may invest, make recommendations regarding securities and assist with portfolio trading. The Board concluded that the

sub-advisory

contracts may benefit the Fund and its shareholders by permitting Invesco Advisers to use the resources and talents of the Affiliated

Sub-Advisers

in managing the Fund. The Board concluded that the nature, extent and quality of the services that may be provided to the Fund by the Affiliated

Sub-Advisers

supported the renewal of the

sub-advisory

contracts.

B.	Fund Investment Performance

The Board considered Fund investment performance as a relevant factor in considering whether to approve the investment advisory agreement. The Board did not view Fund investment performance as a relevant factor in considering whether to approve the

sub-advisory

contracts for the Fund, as no Affiliated

Sub-Adviser

currently manages assets of the Fund.

The Board compared the Fund’s investment performance over multiple time periods ending December 31, 2024 to the performance of funds in the Broadridge performance universe and against the Custom Invesco Municipal Income Opportunities Trust Index (Index). The Board noted that the Fund’s


22		Invesco Municipal Income Opportunities Trust

performance was in the fifth quintile of its performance universe for the one year period and the first quintile of its performance universe for the three and five year periods (the first quintile being the best performing funds on a relative basis and the fifth quintile being the worst performing funds on a relative basis). The Board noted that the Fund’s performance was below the performance of the Index for the one, three and five year periods. The Board considered that the Fund’s overweight exposure to certain sectors, underweight exposure to certain bonds and exposure to certain state bonds detracted from the Fund’s performance during 2024. The Board recognized that the performance data reflects a snapshot in time as of a particular date and that selecting a different performance period could produce different results. The Board also reviewed more recent Fund performance as well as other performance metrics, which did not change its conclusions. The Board also reviewed supplementally historic premium and discount levels of the Fund as provided to the Board at meetings throughout the year.

C.	Advisory and Sub-Advisory Fees and Fund Expenses

The Board received information regarding Invesco Advisers’ approach with respect to contractual management fee schedules and compared the Fund’s contractual management fee rate to the contractual management fee rates of funds in the Fund’s Broadridge expense group. The Board noted that the contractual management and actual management fee rates for shares of the Fund were each below the median contractual management and actual management fee rates of funds in its expense group. The Board noted that the term “contractual management fee” and “actual management fee” for funds in the expense group may include both advisory and certain

non-portfolio

management administrative services fees, but that Broadridge is not able to provide information on a

fund-by-fund

basis as to what is included. The Board also reviewed the methodology used by Broadridge in calculating expense group information, which includes using each fund’s contractual management fee schedule (including any applicable breakpoints) as reported in the most recent audited annual reports for each fund in the expense group. The Board also considered comparative information regarding the Fund’s total expense ratio and its various components.

The Board noted that Invesco Advisers and the Affiliated

Sub-Advisers

do not manage other similarly managed mutual funds or client accounts.

The Board also considered the services that may be provided by the Affiliated

Sub-Advisers

pursuant to the

sub-advisory

contracts, as well as the fees payable by Invesco Advisers to the Affiliated

Sub-Advisers

pursuant to the

sub-advisory

contracts.

D.	Economies of Scale and Breakpoints

The Board noted that most

closed-end

funds do not have fund level breakpoints because

closed-end

funds generally do not experience substantial asset growth after the initial public offering. The Board acknowledged the limitations in calculating and measuring economies of scale at the individual fund level, noting that only indicative and estimated measures are available at the individual fund level and that such measures are subject to uncertainty. The Board noted that the Fund does not benefit from economies of scale through contractual breakpoints, but does share in economies of scale through Invesco

Advisers’ ability to negotiate lower fee arrangements with third party service providers. The Board noted that the Fund may also benefit from economies of scale through initial fee setting, as well as Invesco Advisers’ management of significant assets and investment in its business, including investments in business infrastructure, technology and cybersecurity.

E.	Profitability and Financial Resources

The Board reviewed information from Invesco Advisers concerning the costs of the advisory and other services that Invesco Advisers and its affiliates provide to the Fund and the Invesco Funds and the profitability of Invesco Advisers and its affiliates in providing these services in the aggregate and on an individual

fund-by-fund

basis. The Board considered the methodology used for calculating profitability and the periodic review and enhancement of such methodology. The Board noted that Invesco Advisers continues to operate at a net profit from services Invesco Advisers and its affiliates provide to the Invesco Funds in the aggregate and to most Invesco Funds individually. The Board considered that profits to Invesco Advisers can vary significantly depending on the particular Invesco Fund, with some Invesco Funds showing indicative losses to Invesco Advisers and others showing indicative profits at healthy levels, and that Invesco Advisers’ support for and commitment to an Invesco Fund are not, however, solely dependent on the profits attributed to such Fund. The Board did not deem the level of profits realized by Invesco Advisers and its affiliates from providing such services to be excessive, given the nature, extent and quality of the services provided. The Board noted that Invesco Advisers provided information demonstrating that Invesco Advisers is financially sound and has the resources necessary to perform its obligations under the investment advisory agreement, and provided representations indicating that the Affiliated

Sub-Advisers

are financially sound and have the resources necessary to perform their obligations under the

sub-advisory

contracts. The Board noted the cyclical and competitive nature of the global asset management industry.

F.	Collateral Benefits to Invesco Advisers and its Affiliates

The Board considered various other benefits received by Invesco Advisers and its affiliates from the relationship with the Fund. The Board considered the organizational structure employed to provide these services.

The Board considered that the Fund’s uninvested cash may be invested in registered money market funds advised by Invesco Advisers. The Board considered information regarding the returns of the affiliated money market funds relative to comparable overnight investments, as well as fees paid by the affiliated money market funds to Invesco Advisers and its affiliates. In this regard, the Board noted that Invesco Advisers receives advisory fees from these affiliated money market funds attributable to the Fund’s investments. The Board also noted that Invesco Advisers has contractually agreed to waive through varying periods an amount equal to 100% of the net advisory fee Invesco Advisers receives from the affiliated money market funds with respect to the Fund’s investment in the affiliated money market funds of uninvested cash.

*Effective as of August 29, 2025, Invesco Asset Management Deutschland GmbH merged into Invesco Management S.A.
