Amundi Pioneer Announces Virtual Annual Shareholders’ Meeting for Four Pioneer Closed-End Funds

Pioneer Diversified High Income Trust (HNW), Pioneer High Income Trust (PHT), Pioneer Municipal High Income Trust (MHI) and Pioneer Municipal High Income Advantage Trust (MAV) (each, a “Fund”, and, together, the “Funds”) announced today that, due to the public health impact of the coronavirus (“COVID-19”) pandemic and to support the health and safety of Fund shareholders, the location of the Annual Meeting of Shareholders of each Fund, which are being held together for convenience, (the “Meeting”) has been changed. As previously announced, each Fund’s Meeting will be held on Wednesday, September 16, 2020 at 2:00 p.m. (Eastern Time). In light of public health concerns regarding COVID-19, the Meeting will be held in a virtual meeting format only. The Meeting will be accessible solely by means of remote communication.

As described in the proxy materials for the Meeting previously distributed, the Board of Trustees has fixed the close of business on July 10, 2020 as the record date for the determination of shareholders entitled to notice of and to vote at the Meeting or any postponement or adjournment thereof. If you were a record holder of Fund shares as of July 10, 2020 (i.e., you held Fund shares in your own name directly with the Fund), you can participate in and vote at the telephonic Meeting or any postponement or adjournment of the Meeting. To do so, please email AST Fund Solutions, LLC (“AST”) at [e-mail] and provide your full name, address and control number located on proxy card previously received. If you no longer have that form, please call [phone]. AST will then email you the conference call dial-in information and instructions for voting during the Meeting.

If you held Fund shares through an intermediary (such as a broker-dealer) as of July 10, 2020, in order to participate in and vote at the Meeting, you must first obtain a legal proxy from your intermediary reflecting the Fund’s name, the number of Fund shares you held, and your name and email address. You may forward an email from your intermediary containing the legal proxy or attach an image of the legal proxy, email it to AST at [e-mail] and put “Legal Proxy” in the subject line. Requests for registration must be received by AST no later than 3:00 p.m. Eastern Time on September 15, 2020. You will then receive confirmation of your registration and a control number by email from AST.
