MFS MUNICIPAL INCOME TRUST

# MFS Municipal Income Trust

This closed-end fixed income fund is launched and managed by Massachusetts Financial Services Company, a subsidiary of Sun Life Financial. The trust invests primarily in tax-exempt municipal bonds and notes issued in the United States, generating tax-advantaged income for investors. The fund uses the Barclays Municipal Bond Index as its performance benchmark and targets intermediate-to-long-term municipal debt securities across various credit quality levels and geographic distributions.

The trust generates revenue through management fees charged on its asset base, which constitutes its primary income stream. As a closed-end fund structure, MFS Municipal Income Trust issues a fixed number of shares that trade on the New York Stock Exchange, distinguishing it from open-ended mutual funds. The fund distributes monthly dividend income to shareholders derived from interest payments on its municipal bond holdings.

MFS Municipal Income Trust was established in November 1986 and maintains its domicile in Massachusetts. The fund operates with a relatively modest asset base within the broader universe of municipal bond funds. As a closed-end investment vehicle, it does not disclose traditional operating metrics such as employee count, as its operations are integrated within Massachusetts Financial Services Company's broader asset management platform.
