Cybersecurity Risk Management and Strategy

We have developed and implemented a cybersecurity risk management program intended to protect the confidentiality, integrity, and availability of our critical systems and information.

We design and assess our program based on the National Institute of Standards and Technology Cybersecurity Framework (“NIST CSF”). This does not imply that we meet any particular technical standards, specifications, or requirements, only that we use the NIST CSF as a guide to help us identify, assess, and manage cybersecurity risks relevant to our business.

Our cybersecurity risk management program isintegrated into our overall enterprise risk management program, and shares common methodologies, reporting channels and governance processes that apply across the risk management program to other legal, compliance, strategic, operational, and financial risk areas.

Key elements of our cybersecurity risk management program, include, but are not limited to the following:

•

risk assessments designed to help identify material cybersecurity risks to our critical systems and information;

•

a security team principally responsible for managing (1) our cybersecurity risk assessment processes, (2) our security controls, and (3) our response to cybersecurity incidents;

•

the use of external service providers, where appropriate, to assess, test or otherwise assist with aspects of our security processes;

•

cybersecurity awareness training of our employees, including incident response personnel and senior management;

•

a cybersecurity incident response plan that includes procedures for responding to cybersecurity incidents; and

•

a third-party risk management process for key service providers based on our assessment of their criticality to our operations and respective risk profile.

We havenot identified risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected or are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. We face risks from cybersecurity threats that, if realized, are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. See “Risk Factors –System security risks, data breaches, and cyberattacks could compromise our proprietary information, disrupt our internal operations, impact services to customers, and harm public perception of our products, which could materially adversely affect our business, financial condition, operating results, and future growth prospects”.

Cybersecurity Governance

Our Board considers cybersecurity risk as part of its risk oversight function and has delegated tothe Audit Committee oversight of cybersecurity and other information technology risks, including oversight of management’s implementation of our cybersecurity risk management program.

The Audit Committee receives regular reports from our Chief Information Security Officer (“CISO”) regarding cybersecurity risks, including any significant cybersecurity incidents, as well as any incidents with lesser impact potential. The Chief Information and Customer Officer (“CICO”) and CISO periodically report to the full Board regarding cybersecurity risks and our cyber risk management program. Board members periodically receive presentations on cybersecurity topics from our CICO, our CISO, or external experts as part of the Board’s continuing education on topics that impact public companies.

Our management team, including our CICO and our CISO, is responsible for assessing and managing our material risks from cybersecurity threats. The team has primary responsibility for our overall cybersecurity risk management program and supervises both our internal cybersecurity personnel and our retained external cybersecurity consultants. Our CICO has more than 25 years of information technology leadership experience, including serving as Chief Information Officer at multiple technology companies, where she was responsible for overseeing enterprise technology strategy, operations, and governance. Our CISO has more than 20 years of cybersecurity and risk management experience, including designing and overseeing cybersecurity programs, security operations, compliance frameworks, and risk management initiatives aligned with recognized industry standards and evolving threat landscapes. Additionally, our CISO holds Certified Information Security Manager and Certified in Risk and Information Systems Control certifications. Our CICO and CISO are assisted by a cross-functional Information Security Steering Committee.

Our management team takes steps to stay informed about and monitor efforts to prevent, detect, mitigate, and remediate cybers ecurity risks and incidents through various means, which may include briefings from internal security personnel; threat intelligence and other information obtained from governmental, public or private sources, including external consultants engaged by us; and alerts and reports produced by security tools deployed in the IT environment.
