Item 5.03

Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

The Board of Directors of BigBear.ai Holdings, Inc. (the “Company”) approved and adopted effective December 1, 2025 amendments to the Company’s existing Bylaws (as so amended, the “Amended and Restated Bylaws”) to, among other things:

(i)

amend the voting standard for all matters submitted to the stockholders, other than the election of directors, to the affirmative vote of the holders of majority in voting power of the votes cast (excluding abstentions and broker non-votes) on such matter, unless otherwise provided by applicable law, rule or regulation (including the rules of any stock exchange on which the Company’s shares are listed and traded), by the Company’s certificate of incorporation, as amended from time to time, or the Amended and Restated Bylaws;

(ii)

address the universal proxy rules adopted by the U.S. Securities and Exchange Commission, by clarifying that no person may solicit proxies in support of a director nominee other than the Board’s nominees unless such person has complied with Rule 14a-19 under the Securities Exchange Act of 1934, as amended, including applicable notice and solicitation requirements;

(iii)

clarify and enhance procedural mechanics and disclosure requirements in connection with stockholder nominations of directors and submissions of proposals regarding other business at stockholder meetings, including, without limitation, by requiring additional background information and disclosures regarding nominating or proposing stockholders and other persons related to a stockholder’s solicitation of proxies, and prohibiting a stockholder from nominating a greater number of director candidates than are subject to election by stockholders at the applicable meeting;

(iv)

require that a stockholder directly or indirectly soliciting proxies from other stockholders use a proxy card color other than white; and

(v)

make other technical, conforming, modernizing and clarifying amendments.

The foregoing description of the amendments does not purport to be complete and is qualified in its entirety by reference to the full text of the Amended and Restated Bylaws, a copy of which is attached hereto as Exhibit 3.1 and is incorporated by reference herein.

Item 5.07.

1. The Company’s stockholders voted to approve an amendment to the Company’s Second Amended and Restated Certificate of Incorporation to increase the number of authorized shares of common stock of the Company from 500,000,000 to 1,000,000,000 (“Proposal 1”), by a vote of 191,584,812 shares of common stock for, 44,535,884 shares of common stock against and 3,517,671 shares of common stock abstaining. There were no broker non-votes in connection with this proposal.

2. The Company’s stockholders voted to approve an adjournment of the Special Meeting, if necessary, to solicit additional proxies if there were not sufficient votes at the time of the Special Meeting to approve Proposal 1, by a vote of 199,352,170 shares of common stock for, 31,433,323 shares of common stock against and 8,852,874 shares of common stock abstaining.
