At that time, there were not present or represented by proxy a sufficient number of shares of the Company’s common stock to constitute a quorum. The Company adjourned the Special Meeting without any business being conducted. The adjourned meeting will reconvene on Wednesday, April 9, 2025 at 10:00 a.m., Eastern Time, at the offices of Olshan Frome Wolosky LLP, to vote on the proposals described in the proxy statement filed with the Securities and Exchange Commission (“SEC”) on February 28, 2025. The close of business on February 12, 2025 will continue to be the record date for the determination of stockholders of the Company entitled to vote at the reconvened Special Meeting.

Stockholders may vote in person at the Special Meeting or by submitting a proxy for the Special Meeting. Stockholders of the Company who have previously submitted their proxy or otherwise voted and who do not want to change their vote do not need to take any action. During the period of the adjournment, the Company will continue to solicit votes from its stockholders with respect to the proposals for the Special Meeting.

The Company encourages all stockholders of record as of the close of business on February 12, 2025, who have not yet voted, to do so by April 8, 2025 at 11:59 p.m., Eastern time. Notwithstanding the foregoing, any votes properly received before the close of the adjourned Special Meeting on April 9, 2025 will be accepted. Proxies previously submitted in respect of the Special Meeting will be voted at the reconvened Special Meeting unless properly revoked.
