The Special Meeting will be a virtual meeting only, and will be held via a Zoom video conference. Stockholders will not be able to physically attend the meeting. The virtual meeting can be accessed by using the following link: http://bit.ly/4ofERAH. Any stockholder who is unable to join the online meeting can participate by telephone by dialing (305) 224-1968, and using the Zoom Meeting ID 88104191915 and the Passcode 341409.

As discussed in the enclosed Proxy Statement, the purpose of the Special Meeting is to consider and vote upon the following proposals:

To approve the reservation and issuance of shares of our common stock pursuant to Class I Common Stock Warrants (the “Warrants”), dated September 11, 2025, entered into between us and certain purchasers in connection with a warrant inducement letter dated September 10, 2025, to the extent that issuances under the Warrants may exceed 20% of the Company’s total outstanding shares, which could trigger the share issuance cap under Rule 5635(d) of the Nasdaq Stock Market Rules (the “Exchange Cap”);

Approval of the adjournment of the Special Meeting to the extent there are insufficient proxies at the Special Meeting to approve the forgoing proposal;

To transact such other matters as may properly come before the Special Meeting and any adjournment or postponement thereof.

Our board of directors has fixed October 29, 2025 as the record date for the determination of stockholders entitled to notice of, and to vote at, the Special Meeting and at any adjournment or postponement of the meeting.
