The Audit Committee approved the appointment of Withum as our independent registered public accounting firm to perform independent audit services for the fiscal year ending December 31, 2025. During the fiscal years ended December 31, 2023, and December 31, 2024, and the subsequent interim period through [ ], 2025, we did not consult with Withum regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements, or (ii) any matter that was either the subject of a disagreement (as described in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K and the related instructions). Neither our amended and restated memorandum and articles of association nor other constitutional documents or law require shareholder ratification of the selection of Withum as our independent registered public accounting firm. However, the Audit Committee is submitting the selection of Withum to the shareholders for ratification as a matter of good corporate practice. If the shareholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is 43

ratified, the Audit Committee in its discretion may direct the appointment of different independent auditors at any time during the year if it determines that such a change would be in the best interests of the Company and its shareholders. Information regarding the fees paid to our independent registered public accounting firms in 2024 and 2023 and our pre-approval policies relating to such fees is discussed below.
