Our cybersecurity program includes, among other things:

•ongoing monitoring of systems for security threats at a base level

•an internal team that focuses on higher level threats and conducts threat hunting activities

•monitoring of the cyber threat landscape using a variety of sources, including engagement with domestic and international governmental security agencies, and industry groups

•periodic engagement of third parties to test for vulnerabilities in our information technology systems, assess cybersecurity risk levels, and assess our cybersecurity policies and framework

•compliance audits of our information technology processes by our internal audit team, which also monitors the progress of any remediation activities

•employee training to raise awareness of cyber risks and behaviors that increase vulnerabilities

•periodic exercises to test information technology security protocols

•periodic exercises to test information security protocols to enhance crises management readiness and business continuity capabilities

•systems and processes designed to assess, oversee, identify, and reduce the potential impact of a security incident at a third-party vendor, service provider or customer or otherwise implicating the third-party technology and systems we use

•overseeing alignment with customer cybersecurity requirements

•a Cybersecurity Incident Reporting process

Cybersecurity Incident Reporting Process (“CIR Process”)

Our CIR Process is a formalized approach following the NIST framework for evaluating cybersecurity incidents and prioritizing response efforts based on established criteria. The key components of the CIR Process include:

•Cybersecurity incident prioritization

•Timelines and communications protocols, including establishing reporting thresholds pursuant to which incidents are escalated within the Company, and, where appropriate, reported promptly to the Cyber Review Committee, the Audit Committee Chairman, the Chief Executive Officer and Chief Financial Officer, and the Board of Directors

•Procedures related to our Cyber Review Committee described below

•A formalized methodology for evaluating the impact of cybersecurity incidents

The Cyber Review Committee (“Cyber Committee”) is a sub-committee of our Disclosure Committee comprised of our Chief Accounting Officer; Senior Vice President of Information Technology and Engineering; CISO; general counsels; Vice President – Investor Relations; Director – Risk Management & Insurance; and Vice President – Global Security & Administration. Pursuant to the CIR Process, cybersecurity incidents classified as high priority are reported to the Cyber Committee. The Cyber Committee’s responsibilities include:

Material Cybersecurity Risks and Threats

Risks from cybersecurity threats, including any previous cybersecurity incidents, have not materially affected us, including our business strategy, results of operations or financial condition, and we do not believe that such risks are reasonably likely to have such an effect over the long term. While we have not experienced any material cybersecurity threats or incidents, there can be no guarantee that we will not be the subject of future successful attacks, threats or incidents. Additional information on cybersecurity risks we face can be found in Item 1A—Risk Factors of this Report under the heading “Our business is subject to cybersecurity and information technology system disruption risks,” which should be read in conjunction with the foregoing information.
