VERACYTE, INC.

(a)Evaluation of Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or Exchange Act, which are designed to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Management recognized that disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable, not absolute, assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures.

Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, our disclosure controls and procedures were effective as of September 30, 2026 at the reasonable assurance level.

(b)Changes in Internal Control over Financial Reporting

In the third quarter of 2026, we closed the Convergent Acquisition and the acquisition of certain assets accounted for as a business combination, and we are in the process of evaluating and integrating the internal controls over financial reporting of both acquisitions into our existing operations. Other than the two acquisitions there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the three months ended September 30, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
