MFS Investment Management® (MFS®) announced today that the Board of Trustees of MFS Investment Grade Municipal Trust authorized the Fund to conduct a cash tender offer (the “Tender Offer”) for up to 50% of the Fund’s outstanding common shares (the “Shares”) at a price per Share equal to 99% of the Fund’s net asset value (“NAV”) per Share as of the close of regular trading on the New York Stock Exchange (“NYSE”) on the date the Tender Offer expires. The Board approved the Tender Offer to, among other reasons, encourage shareholder support for the Fund’s previously announced reorganization with and into the MFS Municipal Income Trust (the “Acquiring Fund”) (the “Reorganization”), and to provide shareholders with a source of liquidity ahead of the Reorganization.
As of February 27, 2026, the Fund had 8,199,220 shares of common stock outstanding, 372 shares of preferred stock outstanding, and total net assets of $71.60 million (not including preferred shares).
