About MBMDX

MFS Maryland Municipal Bond Fund Class B is a single‑state municipal bond mutual fund focused on generating income that is generally exempt from federal income tax and Maryland personal income tax, while also considering long‑term total return. The fund primarily invests in investment‑grade municipal securities issued by Maryland state and local entities to finance public projects, employing sector and security selection and yield‑curve analysis to seek consistent tax‑advantaged income. It is managed within a long‑duration profile typical of muni single‑state long peers, reflecting exposure to interest‑rate sensitivity inherent in longer‑maturity bonds. The strategy’s benchmark is the Bloomberg Municipal Bond Index, providing a broad measure of the U.S. municipal market. The fund has been managed for many years by the MFS municipal team, with longstanding portfolio leadership and a track record dating back to the early 1990s for this share class and to the mid‑1980s for the overall strategy. For Maryland residents, its design targets double tax‑free income characteristics, while acknowledging that certain holdings may be subject to the alternative minimum tax and that capital gains distributions remain taxable.
