MFS Investment Grade Municipal Trust Announces Tender Offer

BOSTON--()--MFS Investment Grade Municipal Trust (the "fund") (NYSE: CXH) announced today that it will conduct a cash tender offer to purchase up to 7.5 percent of the fund's outstanding common shares (the “shares”) at a price per share equal to 98 percent 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.

This tender offer follows a tender offer that was completed in September 2017 for 15 percent of the fund's then outstanding shares. The fund announced on July 11, 2017 that it would conduct the tender offer approximately six months after the close of the September 2017 tender offer if the average trading discount of the shares to NAV, calculated based on the simple average of the trading discounts (and premiums, as the case may have been) on each day the NYSE was open for trading, was greater than 6 percent for a specified 90-day period. That condition was met as of March 9, 2018, the end of the 90-day period.

As of February 28, 2018, the fund had 9,848,913 shares of common stock outstanding and total net assets of $101,720,209.

Additional terms and conditions of the tender offer will be set forth in the fund's offering materials. If the number of shares tendered exceeds the maximum amount of the tender offer, the fund will purchase shares from tendering shareholders on a pro-rata basis. Accordingly, there is no assurance that the fund will purchase all of a shareholder's tendered common shares. The fund may determine not to accept shares tendered in the tender offer under various circumstances, as will be set forth in the offering materials. The tender offer is expected to begin on April 3, 2018 and terminate at 5:00 PM Eastern Standard Time on May 2, 2018, unless extended. The pricing date will also be May 2, 2018, unless the tender offer is extended.

Further information about the tender offer will be announced by a future press release. This announcement is for informational purposes only and is not a recommendation, an offer to purchase, or a solicitation of an offer to sell shares of the fund and is not a prospectus, circular or representation intended for use in the purchase or sale of fund shares. The fund has not yet commenced the tender offer described in this release. A tender offer will be made only by an offer to purchase, a related letter of transmittal, and other documents that will be filed with the Securities and Exchange Commission (SEC) as exhibits to a tender offer statement on Schedule TO and will be available free of charge at the SEC's website at www.sec.gov. Shareholders should read the offer to purchase and tender offer statement on Schedule TO and related exhibits when those documents are filed and become available, as they will contain important information about the tender offer. The fund will also make available, without charge, the offer to purchase and the letter of transmittal.
