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

On June 12, 2025, Ideal Power Inc. (the “Company”) held its 2025 Annual Meeting of Stockholders as a virtual meeting online via live audio webcast (the “Annual Meeting”). At the Annual Meeting, there were 5,335,901 shares of common stock represented to vote either in person or by proxy, or 63.92% of the outstanding shares entitled to vote, which represented a quorum. The Company’s stockholders voted on, and approved, the following proposals at the Annual Meeting:

Proposal 1 — Election of five directors to serve until the 2026 annual meeting of stockholders and until their respective successors are elected and qualified.

Proposal 2 — Ratification of the appointment of BPM LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2025.

Proposal 3 — Approval, on a non-binding, advisory basis, the compensation of the Company’s named executive officers.

Proposal 4 — Approval, on a non-binding, advisory basis, of the frequency of future advisory votes on the compensation of the Company’s named executive officers.

As indicated above, approximately 67.51% of the votes cast by stockholders were voted, on an advisory basis, in favor of holding an advisory vote to approve the compensation of the Company’s named executive officers every year. In light of these results, the Board of Directors (the “Board”) of the Company determined that the Company will hold an advisory vote to approve the compensation of the Company’s named executive officers every year until the next required vote on the frequency of future advisory votes to approve the compensation of the Company’s named executive officers, or until the Board otherwise determines that a different frequency for such advisory votes is in the best interests of the Company.
