Commencing on July 15, 2013, the Company sent the following to the Executive Vice Presidents, Senior Vice Presidents and Vice Presidents of the Company.
Dear Partners and Vice Presidents,
Booz Allen Hamilton Holding Corporation will have its 2013 Annual Meeting of Stockholders on August 1, 2013 at 8am in the Newman Auditorium in McLean (doors will open at 7:30am).  As Booz Allen stockholders, you should have received the formal notice and access card(s) in the mail, and may have received more than one depending on how you obtained shares.  If you did not receive the card in the mail, contact Susanna Patton or Terry Kaden in the Law Department. 
Please follow the instructions on the notice and access card(s) you received to vote on the two items noted in our proxy this year: the election of directors and ratification of our independent registered public accounting firm.  These items will be formally addressed at the annual meeting.  I encourage you to vote at any time between now and the meeting at www.proxyvote.com by entering your boxed control number(s) shown on the notice and access card(s).  Only shares of Class A, C, and E common stock owned as of the record date of June 10, 2013 have the right to vote.  Unexercised options (whether vested or not) do not carry any voting rights.
As leaders and owners, I encourage you to join us in person for the Annual Meeting, which we expect to be relatively brief, if you will be in McLean on August 1.  For space planning purposes, please let Susanna (patton_susanna@bah.com) or Terry (kaden_terence@bah.com) know if you plan to attend.
