 notice to the Corporate Secretary must also be in compliance with the Bylaws (including the information requirements therein) and the proxy solicitation rules of the SEC and Nasdaq as applicable. As such, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must comply with the additional requirements of Rule 14a-19 under the Exchange Act including providing notice that sets forth the information required by not earlier than the close of business on December 22, 2025 and not later than the close of business on January 21, 2026. We reserve the right to reject, rule out of order or take other appropriate action with respect to any proposal that does not comply with the foregoing and other applicable requirements.

#### Solicitation by Board; Expenses
The Board is sending you this proxy statement in connection with the solicitation of proxies for use at the Special Meeting. We have engaged Alliance Advisors, LLC to assist in the solicitation of proxies and provide related advice and informational support, for a services fee and the reimbursement of customary disbursements, which are not expected to exceed $17,500 in total. The Company’s directors, officers and regular employees may solicit proxies personally, telephonically, electronically or by other means of communication, but they will not receive any additional compensation for these services. The Company will pay the cost of preparing, assembling, and mailing the proxy materials. The Company has requested brokers, banks and other nominees to send the proxy materials to, and to obtain proxies from, the beneficial owners and the Company will reimburse such record holders for their reasonable expenses in doing so.

Your cooperation in giving this matter your immediate attention and in voting your proxies promptly is appreciated.

By Order of the Board of Directors,

Jeffrey S. Mathiesen 
 Chief Financial Officer, Treasurer and Secretary
