On May 23, 2025, the Company filed a definitive proxy statement (together with the additional proxy statement supplements and annexes, the “Proxy Statement”) with the Securities and Exchange Commission (the “SEC”) in connection with its solicitation of proxies for the Meeting.

Other than as indicated herein, no other changes have been made to the Proxy Statement or the proxy card as originally filed and mailed. Investors and shareholders are also able to obtain, for free, copies of documents filed with the SEC at the SEC’s website at http://www.sec.gov.

If you have already voted, you do not need to vote again unless you would like to change or revoke your prior vote on any proposal. In addition, stockholders who have already submitted a redemption request with respect to the shares held by them may withdraw such request by contacting our Transfer Agent. If you would like to change or revoke your prior vote on any proposal, or reverse a redemption request, please refer to the Proxy Statement for additional information on how to do so.

If you have already submitted a proxy and do not wish to change your vote, you need not take any further action. If you have submitted a proxy and wish to change your vote, you may revoke your proxy at any time before it is exercised at the Meeting as provided in the Proxy Statement. Please note, however, that if your shares are held in street name by a broker or other nominee and you wish to revoke a proxy, you must contact the broker or nominee to revoke any prior voting instructions.

All of the Company’s shareholders of record as of the close of business on May 9, 2025 are entitled to vote at the Meeting. We have retained Advantage Proxy, Inc.
