Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Our cybersecurity risk management program (the “Cybersecurity Risk Management Program”) was designed to identify, manage, mitigate, and respond to ongoing cybersecurity threats and associated risks and is responsible for their escalation to the Board of Directors when determined to be material. The underlying controls utilized by these programs are based on industry recognized best practices and standards for cybersecurity and information technology which include the National Institute of Standards and Technology (NIST) Cybersecurity Framework (CSF) and the International Organization for Standardization (ISO) 27001:2022 Information Security Management Systems Requirements. The Cybersecurity Risk Management Program is administered through two primary channels: (i) Fortrea led cybersecurity services and capabilities, and (ii) trusted third-party partners delivering cybersecurity services overseen by our Cybersecurity leadership team. Both channels combined deliver the entire Cybersecurity Program, which includes key items such as: Cybersecurity risk management program, including, but not limited to, the following: •Risk assessment activities/analyses •Risk Committee oversight, documentation, escalation •Reporting of risk issues deemed material to our Audit Committee of the Board of Directors Global Cybersecurity services, including, but not limited to, the following: •24x7 Security Operations and Incident Response •Identity Access Management support and governance •Security Architecture oversight and guidance •Governance, Risk and Compliance (“GRC”) functions such as third-party risk management, cybersecurity policies, training, and awareness •Independent penetration testing and vulnerability scanning activities conducted by trusted third parties External cybersecurity reviews and assessments performed by third-party risk management, including, but not limited to, the following: •Periodic reviews and assessments measuring cybersecurity services capability and maturity Cybersecurity risks are identified and documented by our cybersecurity team leadership, presented, and reviewed with the Fortrea Cybersecurity Risk Management Committee (the “Risk Committee”) as noted in the Governance of Cybersecurity section below. The Risk Committee, in conjunction with business stakeholders as required, evaluates risks which are presented to them to determine materiality. Cybersecurity risks deemed material are then formally agreed upon as items to be reported by the Chief Information Security Officer (“CISO”) to the Audit Committee. We have established plans to conduct periodic reviews and tabletop exercises to test various processes for preparedness in the event of a critical cybersecurity incident as well as include cybersecurity risk within our Enterprise Risk Management Framework. As part of our overall risk management strategy, we have secured comprehensive cyber insurance coverage. We regularly review and update our cybersecurity insurance coverage to align with the evolving nature of cyber threats and industry standards. Fortrea leverages our internal audit department to provide independent reviews and recommendations to enhance Fortrea’s ability to manage risks effectively, as well as pursue external certifications. Although unknown cybersecurity risks could materialize, including in connection with the implementation of independent systems following the Spin, we are not aware of any disclosures at this time which would be considered material risks and associated with cybersecurity threats or incidents.
