MFS Municipal Trust Tender Offer Oversubscribed, Proration at 86.85%
Event summary
- MFS Investment Grade Municipal Trust's tender offer for 4.1 million shares (50% of outstanding shares) expired May 12, 2026, with 4.7 million shares tendered.
- Proration estimated at 86.85% of tendered shares; final results expected May 18, 2026.
- Purchase price set at 99% of NAV ($8.54 per share as of May 12, 2026).
- Fund's AUM not disclosed, but MFS Investment Management manages $650.7 billion as of April 2026.
The big picture
This oversubscribed tender offer reflects investor demand for liquidity in closed-end municipal funds, a segment where trading often occurs at discounts to NAV. The proration suggests strong interest despite the 1% discount to NAV, highlighting either strategic positioning or tax-related motivations. MFS's $650.7 billion AUM provides scale, but closed-end funds represent a niche within its broader product suite.
