MFS Municipal Income Trust amends its Joint Proxy Statement/Prospectus to update a non‑fundamental investment policy: the abrdn National Municipal Income Fund (VFL) may invest up to 100% of its assets in municipal obligations rated below investment grade or unrated but judged comparable by the manager. The change is effective June 1, 2026 and replaces VFL’s prior 20% limitation; related descriptions comparing VFL and the Fund are revised to reflect that both may hold up to 100% in below‑investment‑grade municipal debt.
The Supplement is dated April 20, 2026.
MFS Municipal Income Trust filed a Supplement No. 1 to its Joint Proxy Statement/Prospectus updating the Fund's investment policy. The Board approved increasing the Fund's allowance to invest in below‑investment‑grade or unrated municipal obligations from up to 20% of net assets to up to 100% of assets. This change is non‑fundamental and becomes effective June 1, 2026. The supplement also aligns the disclosures so that the abrdn National Municipal Income Fund (VFL) and the Fund may each invest up to 100% in below‑investment‑grade municipal debt.

MFS High Income Municipal Trust, MFS High Yield Municipal Trust, MFS Investment Grade Municipal Trust and abrdn National Municipal Income Fund are asking shareholders to approve reorganizations into MFS Municipal Income Trust. Each Target Fund would transfer substantially all assets and liabilities for newly issued common shares (and, where applicable, preferred shares) of the Acquiring Fund, then liquidate and dissolve.
Common shareholders would receive Acquiring Fund common shares with an aggregate net asset value equal to that of their current holdings, except for cash in lieu of fractional shares. For CXE, CMU and CXH, RVMTP preferred shares would be exchanged for Acquiring Fund RVMTP shares with substantially identical terms, while VFL’s MMP preferred shares are expected to be liquidated at liquidation preference plus accrued but unpaid dividends.
The reorganized Combined Fund would remain a diversified closed-end municipal bond fund, able to invest up to 100% of assets in below investment grade municipal debt and continue using leverage. If approved by Acquiring Fund shareholders, Aberdeen would replace MFS as adviser under a new fee schedule of 0.60% of average daily Managed Assets up to $500 million and 0.55% above that, with an expense cap at 0.67% of average daily Managed Assets for at least two years; if Aberdeen is not approved, MFS would remain adviser with an expense cap at 0.71% of average daily net assets including preferred shares.
The boards of all Target Funds unanimously recommend voting for their respective reorganizations, which are intended to qualify as tax-free reorganizations under Section 368(a) of the Code, aside from cash received for fractional shares and taxable distributions of accumulated income and gains before closing.
