 proxy is properly completed, the shares it represents will be voted at the meeting as you instructed. If you submit your properly executed proxy, but do not provide instructions, your proxy will be voted in accordance with the Board’s recommendations as set forth in this Proxy Statement. Brokers holding shares must vote according to specific instructions they receive from the beneficial owners of those shares. If brokers do not receive specific instructions, brokers may in some cases vote the shares in their discretion but are not permitted to vote on certain proposals and may elect not to vote on any of the proposals unless you provide voting instructions. Therefore, unless you provide specific voting instructions, your shares may not be represented or voted at the meeting. If you do not provide voting instructions and the broker elects to vote your shares on some but not all matters, it will result in a “broker non-vote”for the matters on which the broker does not vote. We urge you to promptly provide voting instructions to your broker to ensure that your shares are voted on all of the proposals, even if you plan to attend the Annual Meeting. Revoking Your Proxy You have the right to revoke your proxy at any time before it is voted by (1) filing a written notice with our Corporate Secretary, (2) delivering a new proxy bearing a later date, (3) granting a later proxy through telephone or Internet voting, or (4) attending the Annual Meeting virtually and voting online during the Annual Meeting. Vote Required The presence, in person or by proxy, of the persons entitled to vote a majority of the voting shares at the Annual Meeting is necessary to constitute a quorum at the Annual Meeting. Abstentions and broker non-voteswill be counted for purposes of determining the presence or absence of a quorum. There are different vote requirements for the various proposals:

| • |     | The 13 nominees for director will be elected if the votes cast for the nominee exceed the votes cast against the nominee, with abstentions and broker non-votes not counted either for or against a nominee (and therefore having no effect on the election). |

| • |     | Unless you direct otherwise through your proxy voting instructions, the persons named as proxies will vote all proxies received “for” the election of each director nominee named in this Proxy Statement. If any nominee is unable or unwilling to serve as a nominee at the time of the Annual Meeting, the persons named as proxies may vote for a substitute nominee chosen by the present Board to fill the vacancy. In the alternative, the persons named as proxies may
