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

On December 4, 2025, PROS Holdings, Inc., a Delaware corporation (the “Company”) held a special meeting of stockholders virtually via live webcast (the “Special Meeting”). As of the close of business on October 27, 2025, the record date for the Special Meeting, there were 48,297,780 shares of the Company’s common stock, par value $0.001 per share (“Common Stock”), outstanding and entitled to vote at the Special Meeting. A total of 32,845,275 shares of Common Stock were present or represented by proxy, representing 68% of the votes entitled to be cast at the Special Meeting, which constituted a quorum to conduct business at the Special Meeting.

At the Special Meeting, holders of Common Stock voted on three proposals, as described in further detail in the Company’s definitive proxy statement on Schedule 14A filed with the U.S. Securities and Exchange Commission on November 3, 2025.

At the Special Meeting, the Company’s stockholders were asked to consider and vote on the following matters:

Proposal No. 1 (the “Merger Proposal”) was to consider and vote on the proposal to approve the Agreement and Plan of Merger, dated as of September 22, 2025, by and among the Company, Project Portofino Parent LLC, a Delaware limited liability company (“Parent”), and Project Portofino Merger Sub, Inc., a Delaware corporation and wholly owned direct subsidiary of Parent (“Merger Sub”), to effect the merger of Merger Sub with and into the Company, with the Company surviving such merger as a wholly owned subsidiary of Parent (the “Merger”).

Proposal No. 2 (the “Compensation Proposal”) was to consider and vote on the proposal to approve, by non-binding, advisory vote, the compensation that will or may be paid or become payable to the Company’s named executive officers that is based on or otherwise relates to the Merger.

Proposal No. 3 (the “Adjournment Proposal”) was to consider and vote on the proposal to adjourn the Special Meeting, if necessary, to ensure that any necessary supplement or amendment to the proxy statement was provided to Company stockholders a reasonable amount of time in advance of the Special Meeting, or to solicit additional proxies if there were insufficient votes at the time of the Special Meeting to approve the Merger Proposal.

At the Special Meeting, the Merger Proposal and the Compensation Proposal were approved; however, because the Merger Proposal was approved, the Adjournment Proposal was not necessary.

The final voting results for each proposal are set forth below.

Proposal No. 1 – The Merger Proposal


Votes For	Votes Against	Abstentions
32,757,830	60,712	26,733

Proposal No. 2 – The Compensation Proposal


Votes For	Votes Against	Abstentions
32,208,218	448,642	188,415

No other business properly came before the Special Meeting.
