 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-endmanagement 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-sizetrading 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
