Item 5.02 - Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On March 1, 2024, Mary Ann Cloyd and Dr. Scott Bruder notified Bellerophon Therapeutics, Inc. (the “Company”) of their resignation as a member of the Company’s board of directors (the “Board”), effective immediately. Such resignations did not result from any disagreement with the Company on any matter relating to the Company’s operations, policies or practices.

Item 5.07. Submission of Matters to a Vote of Security Holders.

At a special meeting of stockholders (the “Special Meeting”) of the Company held on March 1, 2024, the following proposals were submitted to the stockholders of the Company:

Proposal 1:   the approval of the liquidation and dissolution of the Company (the “Dissolution”) and the Plan of Liquidation and Dissolution (the “Plan of Dissolution”), which, if approved, will authorize the Board to liquidate and dissolve the Company in accordance with the Plan of Dissolution (the “Dissolution Proposal”); and

Proposal 2:   the approval of an adjournment of the Special Meeting, if necessary, to solicit additional proxies if there are not sufficient votes at the time of the Special Meeting to approve the Dissolution Proposal (the “Adjournment Proposal”).

For more information about the foregoing proposals, see the Proxy Supplement filed with the SEC on February 12, 2024 (the “Proxy Supplement”), which amended and supplemented the Proxy Statement dated November 6, 2023 (the “Proxy Statement”) previously mailed to the Company’s stockholders. At the Special Meeting, there were, represented in person or by proxy, shares of common stock and Series A Preferred Stock representing 16,511,207.767352 votes, or approximately 67.49% of the voting power on the record date, constituting a quorum. As previously described in the Proxy Statement, each share of Series A Preferred Stock was entitled to 12,232,648 votes per share with respect to Proposal 1 and Proposal 2, and no other voting rights except as required by law or as set forth in the Certificate of Designation.

The Series A Preferred Stock entitled the holder thereof to cast on the Dissolution Proposal, the Adjournment Proposal, and any other matter the Board determined (in its sole discretion) was related to the Dissolution Proposal, a number of votes equal to the number of shares of Common Stock outstanding on February 5, 2024, which the Board set as the new record date for the Special Meeting, provided that the holder casts such votes in a manner that is proportionate to the manner in which all shares of Common Stock present, in person or by proxy, at the Special Meeting and entitled to vote on the relevant proposal are voted with respect to such proposal.

The number of votes cast for, against, or withheld, as well as abstentions and broker non-votes, if applicable, in respect of each such proposal is set forth below:

The Company’s stockholders approved the liquidation and dissolution of the Company and the Plan of Liquidation and Dissolution, which authorizes the Board to liquidate and dissolve the Company in accordance with the Plan of Dissolution.

Since there were sufficient votes at the time of the Special Meeting to approve the Plan of Dissolution, the proposal to approve the adjournment of the Special Meeting, if necessary, to solicit additional proxies was not called for at the Special Meeting.
