As part of the enterprise risk management process, the Audit Committee provides regular updates to the full Board on the risk categories for which it is responsible, which includes cybersecurity. The Company has processes by which certain cybersecurity incidents are escalated and where appropriate, reported in a timely manner to the Audit Committee and the Board. Management The Company’s Cybersecurity Group coordinates with business and legal functions to assess and manage the Company’s risks from cybersecurity threats, including those relating to information systems owned or operated by third parties that are used by the Company. The Cybersecurity Group is led by the Director, Cybersecurity (the “Cybersecurity Director”).

The Company’s Internal Audit Group conducts periodic independent audits of the Company’s cybersecurity procedures, systems, and controls, and also provides independent oversight into the engagement of cybersecurity resources.

Risk Management and Strategy Ovintiv’s risk management strategy includes identifying risks, and developing and implementing risk management practices that include mitigation activities, systems, controls and business continuity plans for specific risks, which are aligned with, and complementary to, Ovintiv’s corporate risk management policy. The identification, analysis and mitigation strategy of cybersecurity risk is incorporated into the Company’s risk practices and is a component of an internal Risk Network that is comprised of senior leadership responsible for understanding and reporting each of Ovintiv’s entity-level risks. Our cybersecurity program is aligned with the NIST Cybersecurity Framework and is designed to assess, identify, and manage material risks from cybersecurity threats, and protect and preserve the confidentiality, integrity, and continued availability of all information owned by, or in the care of, the Company. The Company maintains an Information Management Policy, which applies to both employees and third-party service providers, for the protection of the Company’s information. Our information systems are monitored by automated tools and the Cybersecurity Group. The Cybersecurity Group conducts an initial assessment of cybersecurity incidents and determines whether escalation is warranted. The Company’s Cybersecurity Incident Response Program (“CIRP”) provides guidelines to assist the Company in identifying and mitigating cyber risk effectively and efficiently, and sets out a coordinated approach to investigating, containing, documenting and mitigating incidents, including reporting findings and keeping executive leadership and other key stakeholders informed and involved as appropriate. The Company has implemented an incident response team and incident assessment team that includes internal leadership representatives from the executive, information technology, operational, legal, and corporate teams, as well as third-party experts as appropriate. Our processes and procedures also encompass oversight and identification of risks from cybersecurity threats associated with our use of third-party service providers, which includes engagement of a managed security service provider that performs a security review and ongoing monitoring of our third-party service providers. The cybersecurity program, including the CIRP, undergoes periodic internal and external review. The Company engages qualified external auditors and cybersecurity risk assessors to provide independent assessments of our cybersecurity program and response preparedness along with reviews and audits by the Company’s Internal Audit Group. The Company conducts annual internal training for employees, and internal and external teams, including the Cybersecurity Group, as well as periodic penetration testing, red teaming, tabletop exercises and phishing drills. The results of these tests are measured and assessed for potential improvements. The Company is not aware of having experienced any risks from cybersecurity threats or incidents through the date of this Annual Report on Form 10-K that have materially affected or are reasonably likely to materially affect the Company, its business strategy, results of operation or financial condition. This does not guarantee that future incidents or threats will not have a material impact or that we are not currently the subject of an undetected incident or threat that may have such an impact. Additional information on cybersecurity risks we face is discussed in Item 1A. Risk Factors of this Annual Report on Form 10-K, which should be read in conjunction with the foregoing information.
