FY21 ESG Disclosures July 2022 Unaudited 57 Materiality Assessment: 2022 We recognize the need to continually review and refine our materiality assessment and priorities— particularly given the pace of change in our world due to the ongoing effects of COVID-19, global reckoning on social justice, and other geopolitical and macroeconomic factors. Considering such external conditions as well as internal developments, we refreshed our materiality assessment in 2022. Grounded in the stakeholder feedback and results from our 2021 materiality assessment, we also considered recent internal and external inputs and significant business advancements in our updated assessment, including our FY22 to FY24 company strategy , enterprise risk management framework, global Culture Survey (refer to section SOC.3 Inclusion and Diversity - Strategy of this document) and Climate Action Plan . This updated assessment resulted in the elevation of topics such as those related to climate response and project impacts, innovation and digitization and human capital. As reflected in our company strategy , the climate crisis and other mega-trends present us with a unique opportunity to drive growth and long-term value creation around climate response, secure data-driven solutions and consulting and advisory services. It is through our broad range of client solutions that we will be able to not only deliver on this business growth opportunity but amplify the scale of Jacobs’ positive impact on the environment and society. As a professional services company, our people are the heart of our business. Attracting, engaging, advancing and retaining top talent is foundational for us to deliver our company purpose to “create a more connected, sustainable world.” Thus, issues related to human capital are high priorities, including health, safety and wellbeing; inclusion and diversity; and talent attraction, development and retention. Materiality Assessment: Priority Issues The topics listed below reflect the results of our 2022 materiality assessment and the issues we continue to prioritize in our business and sustainability strategies, decision making and reporting. While we have listed these topics with an indication of priority from a global perspective, the relative importance may shift based on local and operational context.
