Item 1C. Cybersecurity.

ITEM 1C. CYBERSECURITY Risk Management and Strategy We have a global cybersecurity program designed to identify, protect, detect, respond to and recover from cybersecurity risks and threats. We regularly assess risks from cybersecurity and technology threats and monitor our information systems for potential vulnerabilities. We use a widely-adopted risk quantification model to identify, measure and prioritize cybersecurity and technology risks and develop related security controls and safeguards. We conduct regular reviews and tests of our cybersecurity program, and monitor the risks associated with third party service providers. Internal audit reviews, penetration and vulnerability tests and other exercises are used to evaluate the effectiveness of our cybersecurity program and improve our security measures and planning. Additionally, organizational risks, including those associated with cybersecurity, are assessed regularly as part of Avient's Enterprise Risk Management program. Cybersecurity education is a priority for our employees and business partners. Employees complete cybersecurity training to help identify and respond to potential cybersecurity risks and reinforce safe behaviors. We also impose security requirements upon our third-party services and software providers, including: maintaining an effective security management program; abiding by information handling and asset management requirements; and notifying us in the event of any known or suspected cyber incident; however, we rely on such third parties to implement security programs commensurate with their risk, and their efforts may not be successful. We have experienced targeted and non-targeted cybersecurity attacks and incidents in the past and we could in the future experience similar attacks. To date, no cybersecurity incident or attack, or any risk from cybersecurity threats, has materially affected or has been determined to be reasonably likely to materially affect the Company or our business strategy, results of operations, or financial condition. Governance Our Chief Information Security Officer (CISO) , who reports to our Chief Information Officer (CIO), is generally responsible for management of cybersecurity risk and the protection and defense of our networks and systems. Avient's CISO has more than two decades of experience in information security across the pharmaceutical, medical device, and insurance sectors. This background includes responsibility for global functions such as data protection, insider risk management, threat detection and response, incident handling, vulnerability management, penetration testing, cloud security operations, and security engineering. The CISO's prior roles include the development and execution of information protection programs, management of third-party security and audit activities, and oversight of compliance initiatives aligned with frameworks and regulatory requirements including the National Institute of Standards and Technology, the International Organization for Standardization 27001, the Sarbanes-Oxley Act, and the Global Data Protection Regulation. The CISO holds professional certifications including Certified Information Systems Auditor (CISA), Certified Information Security Manager (CISM), and Certified Information Systems Security Professional (CISSP). Our CISO is informed about and monitors prevention, detection, mitigation, and remediation efforts through regular communication and reporting from professionals on the information security team, and through the use of technological tools and software and results from third-party audits. Our CISO has a clear escalation path to senior management for cyber-related events. Our CISO manages a team of cybersecurity professionals with broad experience and expertise, including in cybersecurity threat assessments and detection, mitigation technologies, cybersecurity training, incident response, cyber forensics, insider threats and regulatory compliance. Our cybersecurity teams hold relevant certifications, including, but not limited to: CISA, CISM, CISSP, Certified in Risk and Information Systems Control, Factor Analysis for Information Risk (FAIR) Analyst, Security Systems Certified Practitioner (SSCP) or Certified Federal Information Security Management Act Compliance Practitioner. We also supplement our cybersecurity program with third-party experts, who provide assessments of our program, testing of our environment, monitoring support, as well as insights into evolving trends in this space. The Board oversees our annual enterprise risk assessment, where we assess key risks within the company, including security and technology risks and cybersecurity threats. The Audit Committee of the Board has been delegated specific risk oversight responsibilities related to cybersecurity and data protection. The Audit Committee receives regular updates from the CIO or CISO, and, as applicable, the internal audit team, regarding the Company's material risks from cybersecurity threats, cybersecurity defense and detection capabilities, incident response plans and employee training activities. Further, Avient has a Cyber and Data Incident Response Team (CDIRT), which is a cross-functional group established to provide a quick, effective and orderly response to cyber and data related events. The CDIRT's mission is to prevent a material loss of profits, public confidence, or information assets by providing an immediate, effective, and skillful response to any unexpected event in which there is an unauthorized release or access of sensitive information. 13 AVIENT CORPORATION
