Booz Allen stockholders as of June 2, 2025 are eligible to vote on the five items noted in our proxy statement this year. If you held Booz Allen stock as of that date, you should have received instructions via mail or email on how to cast your vote. If you have not received this information, contact Susanna Patton on the Legal, Ethics & Compliance Team.

The five items are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Election of twelve directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for fiscal year 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A non-binding advisory vote on the compensation program for the Company's named executive officers, as disclosed in the Compensation Discussion and Analysis section of the proxy statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Stockholder proposal on political spending; and

These items will be briefly addressed at the Annual Meeting. To participate, visit www.virtualshareholdermeeting.com/BAH2025. You will need the control number located on your proxy card or within the instructions that accompanied your proxy materials. Online check-in will begin at 7:45 am ET.
