Troy Rudd

Chief Executive Officer

Since adopting our Think and Act Globally strategy, sustainability and resiliency have remained paramount in our business decisions, forming the core of our current strategy. Reflecting this commitment, we developed our Sustainability Legacies strategy that ensures we take action across our organization. Over the past year, we've made significant progress on these initiatives, placing us at the forefront of sustainable practices. This has not only extended our competitive advantage as industry leaders but also enabled us to lead more comprehensively, delivering for both clients and the communities we serve. Ultimately, our aim is to create a lasting impact on the planet for future generations.

As we reflect on our achievements and progress made over the past year, I am proud of our team's unwavering commitment and the progress to our purpose of delivering a better world. Our Sustainability Report highlights our ongoing commitment to embedding leading sustainability, resilience and governance practices in everything that we do.

Embracing sustainability in our culture

Our employees are our greatest asset, and we have taken several steps to create the best workplace in our industry, with sustainability and resilience at the center. Last year, this included implementing required sustainability and related training programs to help our employees work safely, sustainably, and ethically. We have achieved strong employee engagement and training compliance due to our efforts for the fourth consecutive year, reflecting our commitment to our workforce and training initiatives. As part of this process our teams are trained on our global sustainability risk framework that aligns with our Sustainable Legacies strategy and is critical in continually assessing project and environmental risks in every decision we make.

This year, we took our initiatives a step further by improving the diversity of our workforce and achieving our near-term goal of women comprising at least 20% of our leadership. We continue to make further progress against our 35% near- term target of women company-wide while also advancing our nongender diversity targets within each region of our business. In addition, we have implemented required unconscious bias training and set specific targets within each of our regions. We also strengthened our professional development programs to help our employees build meaningful careers and foster talent.

I am pleased to report that these actions are receiving positive feedback. In our latest employee survey, a record number of employees recommended AECOM as a great place to work. In addition, our employee retention midway through fiscal 2024 is well ahead of pre-pandemic levels.

We extended these practices focused on social impact by launching our AECOM relief campaign in collaboration with the American Red Cross's Hawaii Wildfires Relief Fund.

Letter from the CEO

AECOM has a long and proud history of delivering for clients and communities across Hawaii, and through this campaign we have made a corporate donation combined with offering a global matching program to collectively raise $300,000 to aid in the challenging recovery. On

a global scale, we partnered with the Government of Ukraine to provide program management and advisory services that will aid in the reconstruction of Ukraine. These are notable examples of the type of initiatives that unify our teams across the world and deliver sustainable legacies for generations to come.

Within AECOM, we have established a culture centered on flexibility, trust, and collaboration. For the tenth consecutive year, we have been recognized as a Fortune World's Most Admired Company, a testament to our continued excellence in our field. Sustaining our recognition is only possible because of the strength of our employees-52,000 talented professionals who are dedicated to our clients and our purpose of delivering

a better world. To ensure we continue fostering a culture focused on impact and providing greater opportunities for our professionals, we continue to invest in professional and technical development programs. In 2023, we also celebrated the value and success of these programs that led to TIME magazine naming us one of the Best Companies for Future Leaders, complementing our status as one of the World's Most Ethical Companies for the eighth year, as recognized by Ethisphere.

Winning with our technical expertise

Over the last year, our ESG Advisory practice, which provides our clients with leading sustainability and resilience- related consulting services, grew a double-digit pace and have made key senior hires in nature-based solutions and the energy transition. Serving as a complement to our world-class program management and advisory services, we have expanded our addressable market to support our clients more holistically across the lifecycle of their investments- from assessing risk and developing

a strategy to the detailed design and execution of the project.

By engaging with our clients earlier and longer, we have created a competitive advantage in our offering. Our global scale and experience are proving to be key differentiators as we are winning work at an all-time sustained high. As part of this, we are winning the work that matters by focusing our environmental technical expertise on the largest and most profitable markets. Critical pursuits such as the UK Network Rail, California High- Speed Rail, and NEOM International Airport highlight the breadth of our advisory and program management services that, when coupled with our technical expertise,

are setting new standards for complex, sustainable infrastructure.

Our progress was no more apparent than in our leading industry recognitions that were announced by the Engineering-NewsRecord in April 2024. In these rankings, we were named the number-one Water design firm, displacing two of our closest competitors, while our number one rankings in Transportation and Facilities design were also reaffirmed. Moreover, our recent acknowledgment from USA Today as one of America's Climate Leaders for 2024 underscores our progress on our environmental commitments. With these recognitions, we are now the top ranked firm across each of our major end markets, further reflecting the tremendous value we bring to clients every day.

Driving sustainable infrastructure

Our commitment to sustainability drives us forward with the latest technology, particularly in our role leading the Sustainable Markets Initiative task force on measurement and transparency. This work has led us to build the innovative and collaborative SMI Nature Risk Tool. Developed in partnership with stakeholders and industry experts, we've created a solution designed to guide early- stage infrastructure decisions. This tool empowers users to assess and address the impact of projects on nature, mitigating risk, and maximizing value. Leveraging global data sets and frameworks, it offers comprehensive insights into biodiversity and ecosystem dependencies. User friendly visualizations simplify complex

data, enabling informed decision making from site selection to risk identification. As we embark on pilot projects, our aim is to democratize access to this transformative tool, advancing sustainable and resilient infrastructure worldwide. Our work on this tool underscores the type of impact we can have as a company to promote and enhance nature and biodiversity.

Looking ahead

We are leading across our markets at a time when sustainability factors have become increasingly important for clients around the globe. This is due to the changing effects of climate change and environmental issues, including evolving regulatory frameworks following continued multi-decade investments in areas such as sustainability and the energy transition. Our clients are increasingly turning to us to navigate these evolving priorities.

We are beginning to witness a surge in momentum in our pipeline from the Infrastructure Investment and Jobs Act (IIJA) and other substantial infrastructure funding initiatives around the world, and we expect substantial growth opportunities on the horizon. We are best positioned to advise and execute on these priorities with our multiple decades of experience and the digital delivery capabilities required to navigate in this changing landscape.

I am incredibly proud of the impact we are making through our sustainability efforts. These are complex challenges that cannot be solved in a day, and, through our Sustainable Legacies strategy, we are committed to continuously improve our capabilities to create infrastructure opportunities for all.

I would like to extend a thank you to our employees, clients, and stakeholders for supporting us on this sustainability journey. Together, we will continue to build a better and more equitable future.
