QT IMAGING HOLDINGS, INC.

Disclosure Controls and Procedures

The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, refers to controls and other procedures that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Evaluation of Disclosure Controls and Procedures

As required by Rules 13a-15 and 15d-15 under the Exchange Act, our Chief Executive Officer and Chief Financial Officer carried out an evaluation of the effectiveness of our disclosure controls and procedures as of September 30, 2025. Based on their evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective.

Material Weaknesses Identified

In connection with the audit of the consolidated financial statements as of and for the fiscal year ended December 31, 2024, we identified a misstatement in the condensed consolidated financial statements for the three-month period ended March 31, 2024, six-month period ended June 30, 2024 and nine-month period ended September 30, 2024 as a result of the material weakness related to technical accounting previously identified for the quarter ended March 31, 2024. We have made significant progress in our remediation efforts during the year ended December 31, 2024 and the quarter ended March 31, 2025, which included implementing technology, hiring personnel, and other activities, including engaging external resources and, as a result, have remediated the material weakness related to technical accounting as of March 31, 2025.

Changes in Internal Control Over Financial Reporting

During the three months ended September 30, 2025, the Company implemented internal controls for the review of technical accounting analyses prepared by third-party technical accounting experts related to significant and non-standard transactions. There were no other changes in our internal control over financial reporting that occurred in the three months ended September 30, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, in designing and evaluating the disclosure controls and procedures, management recognizes that any system of internal control over financial reporting, including ours, no matter how well designed and operated, can only provide reasonable, not absolute assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business but cannot assure you that such improvements will be sufficient to provide us with effective internal control over financial reporting.
