Zoetis Inc.

Disclosure Controls and Procedures

An evaluation was carried out under the supervision and with the participation of the company’s management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based upon that evaluation as of March 31, 2026, the company’s Chief Executive Officer and Chief Financial Officer concluded that the company’s disclosure controls and procedures are effective at a reasonable level of assurance in alerting them in a timely manner to material information required to be disclosed in our periodic reports filed with the SEC.

Changes in Internal Control over Financial Reporting

During our most recent fiscal quarter, there has not been any change in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

We are currently in the process of a multi-year implementation to update our ERP system to a new fully cloud-based system that will replace our existing system. As the phased implementation occurs, it may result in changes to our processes and procedures which may result in changes to our internal controls over financial reporting. As such changes occur, we will evaluate quarterly whether they materially affect our internal control over financial reporting.
