All of our director nominees are currently directors of the Company and, except for Ajay Mehra who was appointed to fill a vacancy after the 2024 annual meeting of stockholders, were previously elected to serve on the Board by our stockholders. The enclosed Proxy will be voted in favor of these individuals unless other instructions are given. If elected, the nominees will serve as directors until our next annual meeting of stockholders, and until their successors are elected and qualified. If any nominee declines to serve or becomes unavailable for any reason, or if a vacancy occurs before the election (although we know of no reason to anticipate that this will occur), the proxies may be voted for such substitute nominees as the Board may designate. REQUIRED VOTE Holders of proxies solicited by this Proxy Statement will vote the proxies received by them as directed on the Proxy or, if no direction is made, for each of the above-named nominees. The election of directors requires a plurality of the votes cast at the Annual Meeting. Proposal 1 is considered a “non routine” matter and, accordingly, brokerage firms and nominees do not have the authority to vote their clients’ unvoted shares on Proposal 1 or to vote their clients’ shares if the clients have not furnished voting instructions within a specified period of time prior to the Annual Meeting. Abstentions and broker non-votes will not be counted as votes cast and will have no effect on the outcome of the vote on Proposal 1. If a quorum is present and voting, the six nominees for directors receiving the highest number of votes will be elected as directors.

| ​ | ​ |     | ​ | ​ | The Board of Directors unanimously recommends a voteFORthe election each of the director nominees. | ​ | ​ |
