Pioneer Municipal High Income Stock Price, News & Analysis

Pioneer Municipal High Income Fund, Inc. (MHI) is a closed-end investment company that traded on the New York Stock Exchange (NYSE) under the symbol MHI. According to regulatory filings, the fund is organized as Pioneer Municipal High Income Fund, Inc. and was listed on the New York Stock Exchange LLC. It operated in the financial services sector within the asset management industry, with a focus on municipal securities through a closed-end fund structure.

The fund is associated with the Pioneer municipal closed-end fund family, which includes Pioneer Municipal High Income Advantage Fund, Inc. (MAV) and Pioneer Municipal High Income Opportunities Fund, Inc. (MIO). These funds are described as closed-end investment companies whose common shares are bought and sold in the open market through a stock exchange and may trade at prices different from their net asset value (NAV). As a municipal high income fund, MHI was designed to hold a portfolio of municipal securities, with investment risks that include the possible loss of principal.

Management and distribution-related information in public communications references Victory Capital Services, Inc. in connection with the funds, and Amundi US in connection with portfolio management of Pioneer closed-end municipal bond funds. Amundi US is described as the US business of Amundi, which is characterized as a large asset manager with global operations and a presence in multiple investment hubs. Within this context, MHI formed part of a broader platform of fixed-income and municipal investment strategies.

As a closed-end fund, MHI issued a fixed number of common shares that were traded on the NYSE rather than being continuously offered. Investors bought and sold shares on the secondary market, and shares could trade at a discount or premium to the fund’s NAV. Public disclosures emphasize that investments in such funds involve risk, including the potential loss of principal, and that distribution rates are not guaranteed and can be affected by factors such as investment income and undistributed net investment income.

Liquidation and Dissolution

MHI’s recent history is defined by a decision to liquidate and dissolve the fund. According to a public announcement, stockholders of Pioneer Municipal High Income Fund, Inc. approved the liquidation and dissolution of the fund pursuant to a Plan of Liquidation and Dissolution adopted by its Board of Directors. Under this plan, the fund will liquidate its portfolio in preparation for one or more cash distributions to stockholders.

Once the fund commenced liquidating its portfolio, it no longer pursued its stated investment objective or normal business activities, except as necessary to wind up its business and affairs, pay its liabilities, and distribute remaining assets to stockholders. The announcement explains that the proceeds of the liquidation will equal the fund’s net asset value after payment or provision for charges, taxes, expenses, and liabilities, including costs associated with liquidating the fund. The fund may make one or more liquidating distributions, and upon payment of the final distribution, all outstanding shares will be redeemed without redemption or other transaction fees.

The same announcement indicates that the fund expected the last day of secondary market trading of its shares on the NYSE to be on or about a specified determination date, after which the fund would cease trading on the exchange. This transition from active trading to liquidation and delisting is a key part of MHI’s status as a fund in wind-down.

Delisting from the New York Stock Exchange

MHI’s delisting from the NYSE is documented in a Form 25 (Notification of Removal from Listing and/or Registration under Section 12(b) of the Securities Exchange Act of 1934). The filing identifies the issuer as Pioneer Municipal High Income Fund, Inc. and the exchange as the New York Stock Exchange LLC. It describes the class of securities as common stock and indicates that the exchange has complied with its rules to strike the class of securities from listing and/or withdraw registration on the exchange.

The Form 25 filing confirms that the NYSE initiated the removal of MHI’s common stock from listing and registration. This filing is a formal regulatory step that follows the fund’s decision to liquidate and cease trading on the exchange. As a result, MHI is no longer listed on the NYSE, and its shares are not traded there following the effective date of the delisting.

Relationship to Other Pioneer Municipal Funds

MHI is frequently mentioned alongside Pioneer Municipal High Income Advantage Fund, Inc. (MAV) and Pioneer Municipal High Income Opportunities Fund, Inc. (MIO). Public communications describe all three as closed-end investment companies that trade on the NYSE under their respective symbols. Each of these funds held a special meeting of stockholders at which stockholders approved the liquidation and dissolution of the fund pursuant to its plan of liquidation and dissolution.

Because the three funds underwent similar processes—special meetings, approval of liquidation and dissolution, and preparation for portfolio liquidation and delisting—MHI’s history is closely tied to this group of Pioneer municipal high income closed-end funds. The liquidation process and the associated regulatory steps, such as the Form 25 filing for MHI, define the later stage of the fund’s lifecycle.

Tax and Investor Considerations (as Described in Disclosures)

Public disclosures related to the liquidation explain that each liquidation will generally be a taxable event for stockholders subject to U.S. federal income tax. A stockholder receiving a distribution in the liquidation will generally realize capital gain or loss equal to the difference between the total amount of liquidation distributions received and the stockholder’s adjusted basis in the fund shares. The same communications note that the sale of fund shares in the secondary market is also generally a taxable event for such stockholders and may be subject to customary brokerage charges.

These disclosures emphasize that investors should consult qualified tax and financial experts regarding the specific tax consequences of the liquidation and the options that may be appropriate for their circumstances. They also reiterate that investments in closed-end funds involve risks, including the possible loss of principal, and that distribution rates are not guaranteed.

Corporate and Management Context

Information about related entities and management appears in public announcements. Victory Capital Services, Inc. is referenced in connection with the funds and investor communications. Another announcement describes portfolio management changes for Pioneer closed-end municipal bond funds, including MHI, and identifies Amundi US as the US business of Amundi. Amundi is characterized as a large asset manager with multiple global investment hubs and a presence in numerous countries, offering fixed-income, equity, and multi-asset investment solutions.

Within this framework, MHI functioned as part of a broader municipal bond platform managed and supported by asset management organizations with significant resources and research capabilities. However, the fund’s own lifecycle has progressed to liquidation and delisting, as documented in stockholder communications and SEC filings.
