Resource and Substance Supply Vulnerability SUSTAINABILITY MANAGEMENT PLAN GOAL Increase traceability of critical mineral resources, and substances used in the supply chain, through data analysis and mitigation for signature programs by 2025. 2021 PROGRESS In 2021, we focused on building awareness of critical mineral resources, identifying the cross- functional team needed to achieve the goal and defining a charter to guide our efforts. The objective of sustainable supply chain management at Lockheed Martin is to ensure alignment of our supplier’s social, ethical, environmental and safety and health responsibilities with our own sustainability commitments. We focus on topics such as conflict minerals, chemical stewardship, environmental impact and counterfeit parts. At a minimum of every three years, we conduct a supplier sustainability voluntary assessment to gain insight into our suppliers’ environmental, social and governance programs to better understand risks and opportunities. In the off-years, we conduct various focus activities, such as our 2020 cybersecurity risk assessment and our 2021 model-based enterprise assessment. In 2021, we elevated the importance of visibility into our complex supply chain. Our new sustainability management plan goal is dedicated to enhancing the tracking and traceability of critical mineral resources. As a downstream user of critical mineral resources, it is challenging to trace the upstream origins of all our product components—from raw material extraction to manufacturers and suppliers to final integration into products at our facilities. Through knowledge of where the raw materials we depend on originate, we can make active purchasing decisions to reduce environmental and social risks in our value chain. This strengthens the long-term viability of our supplier base both domestically and globally. Ultimately, this helps us make sustainability-focused supplier decisions and mitigate the lifecycle impacts of our products. We also focused on building internal awareness, identifying the teams required to provide and analyze resource data and defining our roadmap. We also started a pilot project with one of our signature programs. This pilot program consists of mapping out a selected set of critical mineral resources to their associated product components. We aim to gather lessons learned and expand the effort to other programs throughout the business areas by the end of 2022.
