Pioneer Municipal High Income Advantage Fund Inc. has announced that its stockholders have approved a proposal to liquidate and dissolve the fund. This decision was reached during a special meeting of stockholders held on July 17, 2025. According to the Plan of Liquidation and Dissolution adopted by the fund's Board of Directors, the fund will begin liquidating its portfolio to prepare for one or more cash distributions to its stockholders. During this process, the fund will cease pursuing its stated investment objectives and will focus on winding up its business affairs, settling liabilities, and distributing remaining assets to stockholders. The liquidation proceeds will reflect the fund's net asset value after accounting for all charges, taxes, and expenses. Once the final liquidating distribution is made, all outstanding shares will be redeemed without any redemption or transaction fees.
