Who can participate in this free service?can I expect from BigBear.ai as part of this service?

All shareholders, including beneficial owners, registered shareholders, and participants in
company-sponsored equity or retirement plans.

The service doesn’t limit your voting choices-you can always vote differently on any
proposal. If you opt in but later vote directly on a specific proposal, your vote will override the
Board recommendation. This will only operate to override your standing instruction for the
meeting in question, whereas, if you cancel and opt out of the Program, this will apply to all
proposals brought at all subsequent meetings (except as explained below under “Can I opt
out of the service later?” when you opt out after a definitive proxy statement for an upcoming
meeting has been filed). As always, you’ll receive proxy materials before each meeting,
outlining all the proposals and the Board’s recommendations.

What can I expect after enrolling?

Once you enroll, your shares will be voted according to the Board’s recommendations-no
further action is needed on your part. However, you can change your vote on any proposal at
any time by voting directly; your most recent vote will always take precedence. You will
continue to receive proxy materials before each meeting, which will outline all proposals and
the Board’s recommendations. Such enrollment will take effect beginning with BigBear.ai’s
annual meeting of shareholders to be held in 2026.

Can I opt out of the service later?

You can opt out of the service at any time and at no cost, which will stop your votes from being cast. If you decide to opt out after BigBear.ai has filed a definitive proxy statement for an upcoming meeting, then your opt-out will apply to all future meetings after such upcoming meeting. For such upcoming meeting, you would still be able to change your vote by following the instructions in your proxy materials.

Is there a difference between “opting out” and “cancelling”?

As they relate to the program, the terms “opt out” and “cancel” are used interchangeably.
