Ambiq Micro, Inc.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (as amended), as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on such evaluation, our principal executive officer and principal financial officer have concluded that these disclosure controls and procedures were not effective at a reasonable assurance level as of June 30, 2025, due to the material weakness in our internal control over financial reporting described below.

Background and Remediation of Material Weaknesses

In connection with the preparation of our consolidated financial statements as of December 31, 2024, we identified material weaknesses in our internal control over financial reporting. The material weakness identified relate to controls to address segregation of certain accounting duties and information technology controls. We concluded that the material weakness in our internal control over financial reporting occurred because we did not have the necessary business processes, systems, and related internal controls necessary to satisfy the accounting and financial reporting requirements of a public company.

As part of our plan to remediate this material weakness, we have and will continue to take, certain measures to remediate the material weakness. As part of our remediation plans, we have implemented a new financial system and have enhanced control procedures to mitigate segregation of duties. We have also implemented additional review controls and processes that require additional levels of review by those charged with financial governance of our company.

We will not be able to fully remediate the identified material weakness until the ongoing steps described above have been completed and our internal controls have been operating effectively for a sufficient period of time. We cannot assure you that we will be able to fully remediate the material weakness in a timely manner. We also may incur significant costs to execute various aspects of our remediation plan but cannot provide a reasonable estimate of such costs at this time.

Changes in Internal Control over Financial Reporting

Except with respect to the remediation measures described above, there have been no changes in our internal control over financial reporting identified in connection with the evaluation of such internal control required by Rules 13a-15(d) and 15d-15(d) under the Exchange Act that occurred during the three months ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
