About MMIIX
MFS Municipal High Income Fund Class I is an open-end mutual fund specializing in high-yield municipal bonds. Its core objective is to provide investors with a total return focused on generating high levels of income exempt from federal income tax, while also considering capital appreciation. The fund typically allocates at least 80% of its net assets to municipal securities whose interest payments are federally tax-free. Distinctive to this fund is its emphasis on high-yield—often lower-rated—municipal issuances, thereby offering a higher income potential in exchange for moderately higher risk within the municipal bond space. With over 1,900 holdings and net assets exceeding $4.8 billion as of mid-2025, the fund exhibits substantial diversification across U.S. municipalities and related sectors. The portfolio is managed by an experienced team leveraging robust quantitative tools for risk assessment, aiming for consistent performance. Monthly distributions make it an attractive vehicle for investors seeking a steady tax-advantaged income stream. The fund’s role in the financial markets is to bridge the gap between conservative tax-exempt strategies and income-focused approaches, supporting municipal projects while catering to income-oriented investors prioritizing tax efficiency.
