May 13, 2022 Dear Fellow McDonald’s Shareholder, At McDonald’s Annual Shareholders’ Meeting on May 26, 2022, you face an important decision that may impact the strength and expertise of McDonald’s Board of Directors. We write to you to encourage you to consider this choice carefully and to use the enclosed WHITE proxy card to vote today FOR ALL of McDonald’s Director Nominees. We strongly believe that both individually and collectively, our Directors have the relevant experience, expertise and qualifications that enable them to effectively oversee McDonald’s global operations and long-term priorities, including our Accelerating the Arches growth strategy. The McDonald’s Board is a diverse, highly engaged group of individuals that provides strong, effective oversight of our Company, and will continue working hard on your behalf. Shareholder Value is the Priority – and the McDonald’s Board Has Delivered The Board’s focus on investing in new and existing restaurants – and returning free cash flow to shareholders through dividends and share repurchases – has contributed to best-in-class total shareholder return (“TSR”) over the long- and short-term. In fact, in the last year, McDonald’s delivered TSR1 of 12%, and over the last 5 years, McDonald’s delivered TSR to the tune of 105%, significantly outperforming our peers, the Dow Jones and the S&P 500. While delivering this value to you, the Board has also continued to prioritize best-in-class governance, as well as the issues that matter most to McDonald’s customers and communities, including sustainability, affordability and quality. The McDonald’s Board is Actively Involved in Overseeing our Business, Including our Leading ESG Strategy The Board has the right balance of experience, expertise and perspectives to guide our Company’s ESG strategy. More than half of our directors have significant sustainability and corporate responsibility expertise. The Board’s Sustainability & Corporate Responsibility Committee oversees McDonald’s sustainability priorities, including reviewing and monitoring the development and achievement of our sustainability goals and metrics. Over the past year, this Committee supported the development of our strategy to achieve net zero emissions by 2050 and the publication of our inaugural Climate Risk & Resiliency Report. It also oversaw significant progress on our ESG strategy more broadly, including our animal health and welfare efforts, advancements on packaging and waste issues, and progress on forests and our Diversity, Equity and Inclusion commitments. McDonald’s is a Pioneering Leader on Pig Welfare Under the Board’s leadership, McDonald’s became the first major QSR brand to make a commitment to source from producers who do not use gestation stalls for pregnant sows in 2012. Our commitment was developed with input from animal welfare advocates, including the Humane Society of the United States, veterinary scientists and agricultural experts. It was well understood then, and remains so today, that there is a period of a breeding sow’s life when it should not be housed in a group setting: during the insemination process and until a pregnancy is confirmed, which best promotes a successful pregnancy and supports the economic viability of farming operations. Veterinary experts estimate this period to last 4-6 weeks. Over the course of the past several years, there have been market challenges for farmers and producers, such as the COVID-19 pandemic and global African Swine Fever outbreak, that have slowed progress on phasing out gestation stalls – both for the producers that source pork to McDonald’s suppliers and across the entire industry. Despite these challenges, more than 61% of our U.S. pork supply chain has phased out the use of gestation stalls for confirmed pregnant sows as of the end of 2021, and we expect to source 85% to 90% of our U.S. pork volumes from group housing systems by the end of 2022. We remain committed to phasing out gestation stalls for housing confirmed pregnant sows in the U.S. by the end of 2024. 1 TSR defined as share price performance plus impact of reinvested dividends. One-year TSR reflects period beginning April 28, 2021 and ending April 28, 2022. Five-year TSR reflects five-year period beginning April 28, 2017 and ending April 28, 2022.

Icahn’s Position Does Not Make Sense Scientifically and Would Harm Customers Economically Carl Icahn has asked for new commitments from McDonald’s pertaining to the way our suppliers house pregnant sows. This includes requiring all of McDonald’s U.S. pork suppliers to move to “crate-free” pork and set specific timeframes for doing so. What Mr. Icahn is demanding from McDonald’s – and other companies – is not feasible, as there is not sufficient “crate-free” pork supply available today to meet McDonald’s needs. It also reflects a departure from the veterinary science used for large-scale production throughout the industry. Importantly, it would also impede our ability to provide our customers with high quality products at accessible prices – a key tenet of McDonald’s mission. McDonald’s already pays a premium to purchase group-housed pork in accordance with our 2012 commitment. Sourcing from this niche “crate-free” market would significantly increase these costs. Mr. Icahn’s campaign would have only one clear outcome: a greater financial burden on our customers and our Company. While we believe our customers need choices – and therefore created the McPlant™ – Mr. Icahn’s demand for meatless protein diversification ignores customer preference and would force management to focus on menu items that customers may not want at this time. In addition, this focus is fundamentally at odds with McDonald’s business model, and runs counter to shareholder interests. Icahn’s Single-Platform Nominees Would Not be Valuable Additions to the McDonald’s Board While the Board has steadfastly delivered value to shareholders, Mr. Icahn is using a narrow issue – McDonald’s 2012 pork commitment – as a reason to replace two of McDonald’s highly qualified directors with individuals who lack not only public company board experience, but also the expertise and qualifications needed to contribute meaningfully to the majority of issues regularly faced by the McDonald’s Board. Neither nominee has the knowledge or context, the multinational or international experience, nor the financial or complex supply chain expertise to effectively oversee a large public corporation such as McDonald’s. Vote the WHITE Proxy Card TODAY – Protect the Value that the McDonald’s Board Has Continuously Delivered to You The McDonald’s Board continues to take decisive action in the best interests of you, our valued shareholders, the communities we serve and our customers, all while making progress on some of the world’s most pressing ESG matters of our time. Do not let Mr. Icahn’s narrow campaign unseat two of McDonald’s Directors who bring critical skills and experience to the table. We urge you to use the enclosed WHITE proxy card to vote today FOR ALL of McDonald’s Director Nominees. Please do NOT sign, return or vote any gold proxy card that may be sent to you by the Icahn Group. Your vote is important. Thank you for your continued support and consideration. On behalf of your Board of Directors, Chris Kempczinski President and CEO McDonald’s Corporation
