Ovintiv Inc.

DISCLOSURE CONTROLS AND PROCEDURES

Ovintiv’s Chief Executive Officer and Chief Financial Officer performed an evaluation of the effectiveness of the Company’s disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. The Company’s disclosure controls and procedures are designed to ensure that information required to be disclosed by the Company in reports it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC, and to ensure that the information required to be disclosed by the Company in reports that it files or submits under the Exchange Act, is accumulated and communicated to the Company’s management, including the principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2026.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

For the first quarter ended March 31, 2026, management’s assessment of, and conclusion on, the effectiveness of internal controls over financial reporting did not include the internal controls related to the NuVista Energy Ltd. acquisition that closed on February 3, 2026. Upon closing, NuVista Energy Ltd.’s total assets acquired represented 17 percent of the Company’s consolidated total assets as of March 31, 2026. The assets acquired generated revenues of $159 million for the period from February 3, 2026, to March 31, 2026, which represented six percent of the Company’s consolidated total revenues for the three months ended March 31, 2026. Under guidelines established by the SEC, companies are permitted to exclude acquisitions from their assessment of internal controls over financial reporting for a period of up to one year following an acquisition while integration occurs. The Company is in the process of assessing the internal controls over financial reporting of NuVista Energy Ltd. Except as noted above, there were no changes in the Company’s internal controls over financial reporting during the first quarter of 2026 that have materially affected, or are reasonably likely to affect, the Company’s internal controls over financial reporting.
