- MFS Utilities Fund Class R6 (MMUKX) is an open-end mutual fund managed by MFS Investment Management that seeks total return by investing at least 80% of its net assets in securities of issuers in the utilities industry, including utility stocks with strong growth prospects, related bonds, and convertibles; it maintains a portfolio of approximately 35 holdings, with top positions typically including NextEra Energy Inc., Constellation Energy Corp., PG&E Corp., Xcel Energy Inc., and Sempra; the fund emphasizes U.S. utilities (around 86% allocation) alongside select international exposures in Europe (United Kingdom, Germany, Portugal) and minimal emerging markets. The fund, which commenced operations on February 14, 1992, with the R6 share class launched on June 1, 2012, is domiciled in the United States and benchmarks against the S&P 500 Utilities Index; as of October 31, 2025, it holds net assets of approximately $2.68 billion, a weighted average market cap of $63.6 billion, and a net expense ratio of 0.66%. MFS Investment Management, founded in 1924 and headquartered at 111 Huntington Avenue in Boston, Massachusetts, oversees the fund with global operations including offices in London, Toronto, Hong Kong, Singapore, Sydney, and Tokyo. Recent developments include an announcement on December 1, 2025, of an upcoming portfolio management transition, with long-time manager Claud Davis scheduled to retire effective September 30, 2026, relinquishing his responsibilities; additionally, in December 2025, MFS entered into an agreement with Aberdeen to transfer management of certain closed-end funds totaling £1.5 billion, involving consolidations into larger municipal bond and multi-sector fixed income vehicles, though this pertains to separate CEF strategies rather than MMUKX directly. The fund targets institutional and eligible retail investors seeking sector-specific exposure, with Class R6 shares available without sales charges and quarterly dividend distributions alongside occasional capital gains.
