Notice of Annual Meeting

of Stockholders

Letter from Our CEO

Dear Fellow Stockholder:

It is my pleasure to invite you to our Annual Meeting of Stockholders, which will be held on Monday, August 4, 2025, at the Douglas Conference Center, 8343 Douglas Avenue, Suite 125, Dallas, TX 75225, at 8:00 a.m., local time. We hope that you will attend the meeting, but we encourage you to vote by proxy whether or not you plan to attend the meeting in person.Beginning on June 23, 2025, we are mailing to our stockholders a Notice Regarding the Availability of Proxy Materials, or Notice, instead of a paper copy of the materials for the Annual Meeting—unless they have opted to receive only an electronic distribution of these materials. The Notice contains instructions on how to access the proxy materials over the Internet and vote online, as well as how stockholders can elect to receive paper copies of the materials. We believe that this process expedites stockholders’ receipt of proxy materials and provides stockholders with the information they need.If you attend the Annual Meeting and desire to vote your shares personally rather than by proxy, you may withdraw your proxy at any time before it is exercised. Your vote is very important, whether you own one share or many.Thank you for your continued support and interest in Eagle.

Sincerely, Michael R. HaackPresident and Chief Executive OfficerJune 23, 2025
