About Blackrock Municipal Income Fund, INC.

BlackRock Municipal Income Fund, Inc. is a U.S. closed-end investment fund focused on municipal bonds and, historically, it was listed on the NYSE in the United States. Its core mandate was to deliver current income exempt from U.S. federal income tax by investing primarily in a diversified portfolio of municipal securities. For shareholders, the key strategic development has been the fund’s conversion: the common shares were delisted from the New York Stock Exchange on February 14, 2025, and the vehicle was expected to complete its transition on March 24, 2025 into an unlisted, continuously offered closed-end structure operating as BlackRock Municipal Credit Alpha Portfolio, Inc. That change materially alters liquidity, because investors no longer trade the shares on an exchange and instead rely on periodic repurchase offers.

BlackRock, founded in 1988 and headquartered in New York, is one of the world’s largest asset managers and a major provider of fixed-income, ETF, and active management solutions. The fund benefits from that broader franchise, including BlackRock’s municipal credit research, relative-value analysis, and portfolio construction capabilities. In practice, the fund’s “business lines” are its investment strategy and portfolio management rather than commercial operations. ([blackrock.com](https://www.blackrock.com/us/individual/literature/press-release/6-7-24-mui-conversion-pr.pdf)) Its competitive position has historically been based on three elements: tax-exempt income, access to the U.S. municipal bond market, and the scale of the BlackRock brand. Municipal closed-end funds can be attractive to income-oriented investors seeking after-tax yield, but they also carry interest-rate risk, credit risk, and in this case liquidity risk following the move away from exchange listing. Relative to peers, BlackRock’s advantage is its breadth of fixed-income expertise and its ability to manage a specialized tax-advantaged income portfolio within a large institutional platform. ([blackrock.com](https://www.blackrock.com/us/individual/literature/press-release/6-7-24-mui-conversion-pr.pdf)) Geographically, the fund is overwhelmingly U.S.-focused because it invests in municipal securities issued in the United States and was listed on the NYSE before conversion. Recent material news has centered on the restructuring process: the board approved the conversion to an unlisted interval-fund-style structure in June 2024, BlackRock disclosed the delisting and conversion timetable in December 2024, and in March 2025 the fund announced its final distribution ahead of the conversion to the MUNEX institutional share class. For investors in France, Belgium, and Switzerland, the most important takeaway is that the instrument has moved from a listed closed-end fund to a less liquid private-style interval format, changing how positions can be entered and exited.
