Attention Shareholders: Your Proxy Vote Questions, Answered

By Sean Ricker, Chief Financial Officer

2026 is off to a fast start at BigBear.ai. We’re seeing strong engagement from our shareholders in our proxy vote – many of you will have received and responded to letters, emails and phone calls. We appreciate the time you have taken during a busy holiday season to review the proposal and make your voice heard.

We’re 97% of the way to reaching the required votes, but we aren’t there yet. Leading proxy advisory firms are recommending you vote FOR and 8 in 10 shareholders support the proposal to increase BigBear.ai’s authorized common stock.

If you have not yet voted and have questions, we hope this FAQ helps. It includes simple instructions on how to vote, which take just a minute or two.

There’s still time to participate. The next reconvened Special Shareholder Meeting is on Thursday, January 22, 2026, so you can vote until 11:59 pm ET on Wednesday January 21.

Frequently Asked Questions:

1. What’s the proposal about?
We’re asking shareholders to approve an amendment to our Second Certificate of Incorporation to increase BigBear.ai’s authorized common stock from 500 million to 1 billion shares.

2. Why does it matter?
Having access to available authorized shares has allowed us over the years to make important acquisitions, fund product development, and strengthen our balance sheet. Of the current 500 million authorized shares, very few shares remain. Approval of this proposal will unlock additional shares that help us grow and stay competitive in a rapidly evolving AI marketplace.

3. Who is eligible?
Every BigBear.ai shareholder who held shares on October 14, 2025 is eligible to vote, regardless of the number of shares you owned.

4. Why have you not passed the resolution yet?
As of January 15, 2026, we are 97% of the way to the required votes. The challenge we have is that BigBear.ai has quite a few individual shareholders, so reaching and mobilizing everyone – particularly smaller shareholders – takes time.

5. How do I vote?

6. What is the voting deadline?
If you are voting online, you can cast your vote until 11:59 p.m. ET on January 21, 2026.

It’s a unique number assigned to you to confirm your identity for online proxy voting. You can find your Control Number on your proxy card or Notice of Internet Availability received via mail or email.

8. Can I change my vote if I’ve already voted “Against” or “Abstain”?
Yes, you may change your vote to “For” on the amendment, even if you have already voted “Against” or “Abstain.”

9. What happens if I do not vote?
By not voting, you limit your right to influence an important company decision.

10. Won’t approval of this proposal result in the immediate dilution of my shares?
No, approval of this proposal will not result in the immediate issuance of new shares or have an immediate impact on the company’s shares outstanding. Rather, the additional shares will be available to us in the future to help fuel our growth as we look to:

• Expand our AI capabilities
• Invest in our technology and R&D
• Invest in attracting and retaining top talent and
• Make further strategic acquisitions

11. Where does the Board stand on this proposal?
Our Board unanimously recommends that you vote “For” this proposal. Additionally, leading proxy firms Glass Lewis and ISS have also recommended voting “For” this proposal.
