MATERIALITY MATRIX

Material Topics

The topics and information included throughout this report have been highlighted based on their relevance to our environmental, social and governance strategy and impacts. Report topics include those that are important to our stakeholders and our business. Additionally, we use Global Reporting Initiative (GRI), Task Force for Climate-Related Disclosures (TCFD), Sustainability Accounting Standards Board (SASB), United Nations Sustainable Development Group (UNSDG) and real estate sector standards to guide our reporting topics.

Relevant (or “material”) topics for Macerich are those that directly or indirectly affect the Company’s creation, preservation or erosion of economic, environmental and social value pertaining to the Company, its stakeholders, the environment and society at large. As materiality determination evolves, we increasingly weigh how certain factors can meet a variety of present needs while minimizing their impact on the needs of future generations. Determining materiality for this report included evaluating certain economic, environmental and social impacts for their ability to meet the needs of the present without compromising the needs of future generations. Through transparent reporting on material issues, we build trust and invite stakeholders to understand the Company’s true value and its tangible and intangible assets and to hold Macerich accountable for our impacts and contributions.
