Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes Integrated [Text Block]	Cybersecurity risk is an important and evolving focus for McDonald’s. Significant resources are devoted to protecting and enhancing the security of computer systems, software, networks, storage devices, and other technology. The Company’s security efforts are designed to protect against, among other things, cybersecurity attacks that can result in unauthorized access to confidential information, the destruction of data, disruptions to or degradations of service, the sabotaging of systems or other damage. McDonald’s has implemented measures and controls that it believes are reasonably designed to address the evolving cybersecurity risk environment, including enhanced threat monitoring. In addition, McDonald’s continues to regularly review its capabilities to address associated risks, such as those relating to the management of administrative access to systems. Third parties that help to facilitate the Company’s business activities (e.g., franchisees, vendors, suppliers, service providers, etc.) are also sources of cybersecurity risk to McDonald’s, and we have various processes and programs to manage cybersecurity risks associated with our third parties. Despite these risk-mitigation measures, a cybersecurity event impacting a third party may compromise Company data or negatively impact the Company’s ability to conduct business, which could have a material adverse effect on our business. Risks from cybersecurity threats, including as a result of any previous cybersecurity events, did not materially affect McDonald’s or its business strategy, results of operations or financial condition in 2025. Notwithstanding having what McDonald’s believes to be a comprehensive approach to address cybersecurity risk, no company is immune to cybersecurity threats, and McDonald’s may not be successful in preventing or mitigating a future cybersecurity incident that could have a material adverse effect on McDonald’s or its business strategy, results of operations or financial condition. In evaluating cybersecurity incidents, management considers the potential impact to the Company’s results of operations, control framework, and financial condition, as well as the potential impact, if any, to our business strategy and/or reputation. For additional information on risks from cybersecurity threats, please see our Risk Factors beginning on page 27.
Cybersecurity Risk Role of Management [Text Block]	Management has primary responsibility for enterprise-wide risk management (“ERM”), including cybersecurity risk, within our Company, as detailed below. Our Board of Directors (the “Board”) is responsible for overseeing our ERM framework and exercises this oversight both as a full Board and through its standing committees. Our Board’s Audit & Finance Committee (“A&F Committee”) has oversight responsibility for our strategy and processes relating to cybersecurity risk management. Our A&F Committee receives updates at regular intervals on cybersecurity matters from management, including our Global Chief Information Officer (“CIO”) and Global Chief Information Security Officer (“CISO”) who, as discussed below, are responsible for assessing and managing material cybersecurity risks. Such updates include discussion of the status of our cybersecurity landscape and our cybersecurity strategies, including potential risks and mitigation efforts. For certain significant cybersecurity incidents, our procedures contemplate accelerated reporting of the incident to the applicable members of the Board. The A&F Committee also considers potential remedies to any strategic or process gaps that may be identified during the Company’s review of specific cybersecurity incidents. Our Board recognizes the importance to the Company of effectively identifying, assessing and managing risks that could have a significant impact on our business strategy. The ERM framework leverages internal risk committees comprised of cross-functional leadership who meet regularly to evaluate and prioritize risks, including cybersecurity risk, in the context of our strategy, with further escalation to our CEO, Board and/or Committees, as appropriate. Effective management of cybersecurity risks is critical to the successful execution of our business strategy.
Cybersecurity Risk Management Positions or Committees Responsible [Text Block]	The CISO reports to the CIO. McDonald’s CIO and CISO are responsible for assessing and implementing our cybersecurity risk management programs, which are informed by the National Institute of Standards and Technology (NIST) Cybersecurity Framework. These leaders and their teams have significant relevant experience in various fields, such as incident response, application security, data security, network security and identity and access management, and have implemented and executed security programs across multiple industries at Fortune 100 companies. Our programs are designed to create a comprehensive, cross-functional approach to identify, assess, manage and mitigate cybersecurity risks as well as to mitigate cybersecurity incidents to support business continuity and achieve operational resiliency. The CISO leads the Global Cybersecurity organization, which is responsible for executing the Company’s Global Cybersecurity Program and initiatives. This global program is responsible for identifying technology and cybersecurity risks and for implementing and maintaining controls to manage cybersecurity threats. These controls are designed to mitigate, detect and respond to cybersecurity incidents to help safeguard the confidentiality, integrity and availability of McDonald’s infrastructure, resources and information. McDonald’s Global Cybersecurity Program includes the following functions: •Cybersecurity Services, which is responsible for deploying and operating the frontline security controls that are designed to protect and defend McDonald’s against cyber-attacks. Cybersecurity teams are focused on specific areas of a layered defense, including Network Security, Endpoint Protection, Identity and Access Management, Data Security, and others, to ensure that these controls are integrated into critical systems and processes throughout the McDonald’s environment and operating effectively. •Cyber Defense, which is responsible for implementing and maintaining controls designed to detect and respond to cybersecurity incidents against McDonald’s and includes a dedicated function for incident response and regular monitoring for cybersecurity threats and vulnerabilities, including those among McDonald’s third-party suppliers. The Company has established and regularly tested incident response processes and controls that identify and risk-rank incidents through a centralized system to promote timely escalation of cybersecurity incidents that exceed a particular level of risk, including escalation of incidents of sufficient magnitude or severity to the CIO and CISO. •Cyber Governance, Risk & Compliance, which is responsible for operationalizing technology risk and control frameworks, analyzing regulatory developments that may impact McDonald’s, and developing control catalogs and assessments of controls, as well as overseeing governance and reporting of technology and cybersecurity risk. The team provides awareness and training that reinforces information risk and security management practices and compliance with McDonald’s policies, standards and practices. The training is mandatory for all employees globally on a periodic basis, and it is supplemented by Company-wide testing initiatives, including periodic phishing tests. •Cyber Market Engagement, which is responsible for working with our market teams, International Developmental Licensee partners, and other entities to ensure a consistent approach for cybersecurity across the McDonald’s system. The governance structure for the Global Cybersecurity organization is designed to appropriately identify, escalate, and mitigate cybersecurity risks. Cybersecurity risk management and its governance and oversight are integrated into McDonald’s operational risk management framework, including through the escalation of key risk and control issues to management and the development of risk mitigation plans for heightened risk and control issues. As needed, McDonald’s engages third-party assessors or auditing firms with industry-recognized expertise on cybersecurity matters to review specific aspects of McDonald’s cybersecurity risk management framework, processes and controls. These efforts include a wide range of activities focused on evaluating the effectiveness of the program, including audits, modeling, tabletop exercises and vulnerability testing.
