Pioneer High Income Fund Inc. has announced that its stockholders have approved the proposal to liquidate and dissolve the fund. This decision was finalized at a special meeting, leading to the adoption of a Plan of Liquidation and Dissolution by the Board of Directors. The fund will now begin liquidating its portfolio, ceasing its usual investment activities to focus on winding up its business.

Upon completion of the final liquidating distribution, all outstanding shares will be redeemed without any transaction fees.
