holders hold their shares in more than one account and may receive separate proxy cards or voting instructions forms for each of those accounts. If you receive more than one proxy card, your shares are registered in more

than one name or are registered in different accounts. Please sign, date and return or otherwise submit your proxy with respect to each proxy card to ensure that all of your shares are voted. If no instructions are indicated, shares on a properly executed proxy will be voted:

| • |     | FOR ALLthe ten (10) director nominees identified in this Proxy Statement and on the proxy card;                                                              |
| • |     | FORthe non-binding resolution to approve the compensation of our named executive officers;                                                                   |
| • |     | FORthe approval of an amendment to our 2016 Long-Term Incentive Plan; and                                                                                    |
| • |     | FORthe ratification of the appointment of Ernst & Young to serve as our independent registered public accounting firm for the year ending December 31, 2025. |

In respect of any other matters that may properly come before the Annual Meeting, shares represented by properly executed proxies may be voted at the discretion of the proxy holder. The Board is not currently aware of any other matters to be presented at the Annual Meeting. Revocation of Proxies A stockholder who has executed and returned a proxy may revoke it at any time prior to its exercise at the Annual Meeting by executing and returning a proxy bearing a later date by mail, by voting via the Internet, by filing with our Corporate Secretary a written notice of revocation bearing a later date than the proxy being revoked, or by voting the Common Stock covered thereby virtually at the Annual Meeting. In order to revoke a proxy executed with respect to shares held in street name, the stockholder must contact the appropriate broker or nominee. Virtually attending the Annual Meeting will not cause your previously granted proxy to be revoked unless you specifically make that request or vote in person at the Annual Meeting.
