Because the approval of Proposal No. 1 requires the approval by the holders of at least 50% of each Target Fund’s outstanding shares and by the holders of at least 50% of each Fund’s outstanding preferred shares voting separately, abstentions and broker non-votes, if any, will have the same effect as a vote against the proposal. Because Proposal 2 requires the approval of a majority of votes cast, abstentions and broker non-votes will have no effect on the outcome of Proposal No. 2 because they are not a vote cast. Because the election of Board Members does not require that a minimum percentage of outstanding shares be voted in favor of any nominee, assuming the presence of a quorum, abstentions will have no effect on the outcome of the vote on Proposal No. 3.

Pursuant to Rule 452 of the NYSE, certain preferred shares held in “street name” as to which voting instructions have not been received from the beneficial owners or persons otherwise entitled to vote as of one business day before a Fund’s Meeting, or, if adjourned or postponed, one business day before the day to which the Meeting is adjourned or postponed, may be voted by the broker on a proposal in the same proportion as the votes cast by all holders of such preferred shares who have voted on a proposal. Such provisions of Rule 452 do not apply to the preferred shares of the Acquiring Fund or the Target Funds based on their current terms.

Broker-dealers who are not members of the NYSE may be subject to other rules, which may or may not permit them to vote your shares without instruction. We urge you to provide instructions to your broker or nominee so that your votes may be counted.

Those persons who were shareholders of record of a Fund as of the close of business on [•] and entitled to vote at the Fund’s Meeting will be entitled to one vote for each share held and, with respect to holders of common shares, a proportionate fractional vote for each fractional common share held.

As of July 31, 2025, for each Fund, the shares of the Funds issued and outstanding are as follows:

| Fund                   
 (Ticker Symbol)        |     |      Common 
   Shares(1) |     |      VRDP
