Leadership Perspectives Chairman, President and Chief Executive Officer Letter At Lockheed Martin, we recognize the long-term success of our stakeholders is tied inextricably to the sustainability of our operations and the enduring relationships we have with global customers and in communities where we live and work. The rapidly evolving challenges of the 21st century compel us to accelerate innovation and deliver the advanced solutions our customers need to promote security, enhance international cooperation, and advance scientific discovery. Our commitments to providing innovative products and services and to operating as a sustainable enterprise stem from our Core Values – Do What’s Right, Respect Others and Perform with Excellence. Achieving progress requires that we identify priorities among environmental, social and governance issues and direct investment and resources so our teams are empowered and focused. One important action we are taking in this effort is harnessing the full benefits of digital transformation to increase the efficiency of our operations and processes. We’re investing heavily to introduce new ways to digitally design, test, manufacture, and sustain our products so we can deliver more capable solutions more quickly and more efficiently. Our transformation efforts are reflected in Lockheed Martin’s 2025 Sustainability Management Plan (2025 SMP), which is our five-year sustainability roadmap to carry out our vital mission. Our 2025 SMP includes four core priorities: • Advancing Resource Stewardship: We strive to use resources in the most efficient way possible and to minimize the environmental footprint of our operations. • Elevating Digital Responsibility: We protect data, privacy, and intellectual property and use artificial intelligence (AI) in an ethical manner. • Fostering Workplace Resiliency: We maintain an inclusive and safe environment in which we value individual employees’ unique contributions to the success of our team and provide ample opportunities for their professional development and career growth. • Modeling Business Integrity: We operate ethically and ensure that everyone who works with us – both inside and outside Lockheed Martin – adheres to the same high ethical standards. During 2021, we completed the first full year of implementation for our 2025 SMP. We completed our first Zero Waste Challenge to minimize waste throughout our operations. We also committed $2 million to The Nature Conservancy as part of the Department of Defense’s (DoD) Readiness and Environmental Protection Integration Challenge, contributing to the resiliency of the DoD’s vital infrastructure nationwide. And we published our inaugural Human Rights Report, showing how our company is committed to upholding human freedom and well-being throughout our operations and supply chain. Lockheed Martin was honored to be acknowledged globally for our commitment to sustainability. We once again earned a spot on the Dow Jones Sustainability World Index and North American Index based on best-in-class sustainability practices. For the third year in a row, Forbes and JUST Capital recognized us as one of America’s Most JUST Companies. We were selected as a 2021 ENERGY STAR Partner of the Year Sustained Excellence Award winner. We also received the Gold Brandon Hall Excellence Award for Best Advance in Social Impact Innovation. Looking ahead, we plan to expand training to our AI developers to further the incorporation of ethical principles into their system engineering approaches. We will continue to engrain responsible data usage into our company’s culture by providing new data literacy training and engagement to at least half of our workforce. We also intend to double our level of corporate giving tied to specific United Nations Sustainable Development Goals by 2030. In the pages that follow, you will find more detailed information about our progress in implementing our 2025 SMP and how it drives value for our company, our shareholders, and our communities. I am proud of our team’s tremendous accomplishments in 2021. As we look to the future, I am confident that Lockheed Martin will continue to demonstrate how sustainable business practices enable better solutions for our customers and stewardship of our vital operations for generations to come.
