Western Asset Muni High Income SEC Filings

Western Asset Municipal High Income Fund Inc. seeks high current income exempt from federal income tax by investing mainly in intermediate- and long-term municipal bonds, including below-investment-grade “junk” bonds without limit. Over the year ended October 31, 2025, the U.S. bond market was volatile but positive as the Federal Reserve cut rates several times and Treasury yields drifted lower.

For the period, the Fund returned 2.64% based on net asset value (NAV) and 6.77% based on its New York Stock Exchange market price, compared with 4.17% for the Bloomberg Municipal Bond Index. An overweight to electric utilities and pre-refunded bonds helped performance, while interest-rate positioning, an underweight in housing, and security selection in industrial revenue and transportation hurt.

The Fund paid $0.41 per share in distributions, of which $0.16 was a return of capital for tax purposes. Net investment income was $5.37 million, and net assets were $155.2 million, or $7.00 NAV per share. The Fund used tender option bond leverage and modestly raised new equity through a shelf offering, selling 453,714 shares for about $3.27M.

Form 3 filed for Jeffrey Masom reporting relationship to Western Asset Municipal High Income Fund, Inc. (MHF). The filing states Mr. Masom is an officer serving as a Director-Subadviser and that no securities are beneficially owned. The event date requiring the statement is 04/29/2025. The form is signed by Mitchell O'Brien by power of attorney on 08/28/2025.
