DXC Technology 10-K cybersecurity disclosure (Item 1C), fiscal 2026

ITEM 1C. CYBERSECURITY

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 is integrated into our overall enterprise risk management ("ERM") program, and shares common methodologies, reporting channels and governance processes that apply across the ERM 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 and penetration testing 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 such as forensic analysts, third party security reviewers, and other consultants such as outside counsel, 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, suppliers, and vendors based on our assessment of their criticality to our operations and respective risk profile.

We have not identified risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected 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 – We could be held liable for damages, our reputation could suffer, and our business may be materially impacted due to service interruptions from security breaches, cyber-attacks, other cybersecurity events or incidents or disclosure of confidential information or personal data. "

There can be no assurance that our cybersecurity risk management program and processes, including our policies, controls or procedures, will be fully implemented, complied with or effective in protecting our systems and information.

Cybersecurity Governance

Cybersecurity is considered a critical risk area at DXC and is integrated into the Company's overall ERM program, which includes maintaining the ERM framework, evaluating risk appetite, and monitoring evolving risks and the effectiveness of mitigations. Our Board considers cybersecurity risk as part of its risk oversight function and has delegated to the Nominating/Corporate Governance Committee oversight of cybersecurity and other information security risks. The Nominating/Corporate Governance Committee oversees management's efforts to identify, assess, mitigate, and remediate material information security risks. Similarly, the Audit Committee oversees our disclosure controls and procedures, which include cybersecurity reporting disclosure controls.

The Nominating/Corporate Governance Committee receives reports from the Global Chief Information Security Officer ("Global CISO") on the Company's information security program at each regular quarterly Committee meeting. In addition, management updates the Nominating/Corporate Governance Committee, where it deems appropriate, regarding any cybersecurity incidents it considers to be significant. The Nominating/Corporate Governance Committee chair then provides an overview of the information security reports to the full Board at each regular quarterly Board meeting.

Our management team, including our Global CISO, Chief Information Officer, Managing Director of Global Infrastructure Services, and General Counsel, along with other key business and functional leaders, constitute our Security Steering Committee ("SCC") which is responsible for assessing and managing our material risks from cybersecurity threats. Our Global CISO and our Managing Director of Global Infrastructure Services have primary responsibility for our overall cybersecurity risk management program and supervise both our internal cybersecurity personnel and our retained external cybersecurity consultants. Our Global CISO has extensive experience assessing and managing cybersecurity-related risks and implementing related policies, procedures, and strategies. Our Global CISO has served in leadership roles related to information security for over 23 years, including serving as a CISO at another company since 2015, then as DXC's IT CISO since May 2022 and as DXC's Global CISO since August 2024. Our Global CISO reports to our Managing Director of Global Infrastructure Services who is a well-known industry leader with more than 20 years of experience in the technology industry and has been with DXC since 2020.

Our management team takes steps to stay informed about and monitor efforts to prevent, detect, mitigate, and remediate cybersecurity 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 our IT environment. The SCC also analyzes emerging global cyber security risks and uses the expertise of its members to review DXC's current security posture and consider steps to take to mitigate such risks and implement improvements where it deems necessary.
