FY21 ESG Disclosures July 2022 Unaudited 5 GENERAL GEN.1 Jacobs ESG Reporting Jacobs has reported on a wide range of Environmental, Social and Governance (ESG) issues through our annual ESG Disclosures since 2019. We have also reported on ESG issues via our Integrated Annual Report, Form 10-K, Proxy Statement, and other public materials. This report is focused on our priority ESG data that we believe is the most relevant to our business and important to our stakeholders. This report is aligned to the Sustainability Accounting Standards Board ( SASB ) framework and informed by Global Reporting Initiative ( GRI ) standards. Annually, we disclose to CDP (formerly the Carbon Disclosure Project) and the S&P Global Corporate Sustainability Assessment, ( CSA ), which is the basis for the S&P Global ESG Score and a key factor for inclusion in the Dow Jones Sustainability Indices . We disclose our climate risk data in line with the Task Force on Climate-related Financial Disclosures ( TCFD ) recommendations. We also regularly engage with leading ESG rating and ranking organizations to review and improve the accuracy of their data regarding our ESG performance. We understand and champion the increasing appetite for ESG metrics and transparency. We take a pragmatic approach to our disclosures, focusing on what is material, what is a risk or opportunity, and what makes sense for our business. We look forward to a consistent, industry-wide reporting framework that serves the investor community and reduces reliance on lagging indicators—allowing companies to be more efficient and focused on improving ESG performance. This document covers activities in fiscal year 2021 (FY21) for Jacobs from October 3, 2020, to October 1, 2021. Our FY20 report was released in January of 2021 and was last updated in July 2021. Jacobs meets current Securities and Exchange Commission (SEC) climate change related disclosure obligations in our Annual Report on Form 10-K. Jacobs will release an ESG disclosure document annually and will make periodic updates as required by new SEC rules and regulations and as additional information is obtained or to fulfill stakeholder requests for disclosures. We apply an operational control approach as the boundary for our ESG reporting. On March 3, 2021, Jacobs acquired a 65% stake in PA Consulting. In alignment with the greenhouse gas (GHG) Protocol, our investment in PA Consulting is included within our scope 3 GHG emissions data for FY21, which includes GHG emissions outside of our operational control. PA Consulting is otherwise excluded from our ESG reporting in this document. For more information on our approach to integrating PA Consulting into our GHG emissions inventory, see section ENV.6 GHG Emissions - Scope 3 (Indirect) . We also acquired BlackLynx, Inc. in November 2021 and Street Light Data, Inc. in February 2022. These acquisitions are not included in this report because they were consummated in FY22. Additionally, ESG and GHG data from our Joint Ventures are not within the reporting boundary of this report. For questions regarding this document, please contact: [email protected] . GEN.2 Assurances and Verification This document has gone through internal review by subject matter experts, legal experts and internal auditors to confirm accuracy of the contents as of the time of publication, but only our GHG emissions data reported here was externally verified, with limited assurance. In the future, we intend to obtain independent assurance of additional data, including social indicators. This document and the data within should be considered unaudited. Certain information reported herein contains estimates or is based on assumptions. Furthermore, forward-looking information in the report, including our goals, plans and expectations, involve risks and uncertainties that may result in our not achieving goals or cause actual results to differ materially from those expressed or implied. Our FY21 Form 10-K (pp. 21–46) contains a discussion of some of the risks and uncertainties that could cause our actual results to differ from our plans and expectations.
