Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On April 16, 2026, the board of directors (the “Board”) of FibroBiologics, Inc. (the “Company”) amended and restated the Company’s Amended and Restated Bylaws (the “Bylaws”) to amend Section 2.07 of the Bylaws to change the requirement for quorum at a meeting of the stockholders of the Company from a majority of voting power to one-third of the voting power (the “Amendment”).

Prior to the Amendment, Section 2.07 of the Bylaws read in its entirety:

“Section 2.07 Quorum. Unless otherwise required by law, the Certificate of Incorporation or these Bylaws, at each meeting of the stockholders, a majority in voting power of the shares of the Corporation entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum. If, however, such quorum shall not be present or represented at any meeting of the stockholders, the chair of the meeting or the stockholders entitled to vote at the meeting, present in person or represented by proxy, shall have power, by the affirmative vote of a majority in voting power thereof, to adjourn the meeting from time to time, in the manner provided in Section 2.04, until a quorum shall be present or represented. A quorum, once established, shall not be broken by the subsequent withdrawal of enough votes to leave less than a quorum. At any such adjourned meeting at which there is a quorum, any business may be transacted that might have been transacted at the meeting originally called.”

Following the Amendment, Section 2.07 of the Bylaws now reads in its entirety:

“Section 2.07 Quorum. Unless otherwise required by law, the Certificate of Incorporation or these Bylaws, at each meeting of the stockholders, the holders of one-third in voting power of the shares of the Corporation entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum for the transaction of business. If, however, such quorum shall not be present or represented at any meeting of the stockholders, the chair of the meeting or the stockholders entitled to vote at the meeting, present in person or represented by proxy, shall have power, by the affirmative vote of a majority in voting power thereof, to adjourn the meeting from time to time, in the manner provided in Section 2.04, until a quorum shall be present or represented. A quorum, once established, shall not be broken by the subsequent withdrawal of enough votes to leave less than a quorum. At any such adjourned meeting at which there is a quorum, any business may be transacted that might have been transacted at the meeting originally called.”
