Notice of 2021 Annual Meeting of Stockholders & Proxy Statement

DE AR STOCK HOLDERS: It’s been said that the true strengths of an organization are best measured during difficult times. Over the past year, in the face of a public health emergency and unprecedented operating conditions due to a once-in-a-century pandemic, AECOM consistently delivered for our people, clients, communities and stockholders. We kept our people safe and employed, achieved double-digit adjusted1 EBITDA2 growth, expanded project backlog and advanced our transformation into a lower-risk, higher-margin professional services firm. We also launched our comprehensive Think and Act Globally strategy to further improve how we work, deepen client relationships, better focus our exper tise and market-leading capabilities for growth and set new standards for technical excellence in our industry. Troy Rudd Chief Executive Officer also established an internal practitioner-led ESG council focused on delivering on our sustainabilit y, diversit y and inclusion commitments to our people, communities and clients, reflecting our position as a signator y to the UN Global Compact. I believe our organization is stronger today because of the adversity we overcame during the 2020 fiscal year. The resiliency of our people, our innovation and agility, and the indispensable partnerships we have forged with our clients through this crisis set us on a solid path to sustain growth and forge new market leadership. I could not be prouder of what our professionals achieved in the past year, and we are energized by the opportunities we have in front of us. As a leading professional services provider, the number-one ranked environmental services firm globally, a leader in key water sectors, the leading transpor tation design f irm and a leading green designer and construction manager, we are well positioned to help our clients meet new requirements in addressing environmental, social and governance (ESG) factors that lead to improved outcomes. Rising above the pandemic The pandemic had profound impacts on the lives of our employees and their families, our clients and communities. Yet our people mobilized safely and quickly to provide extraordinar y suppor t and disaster response work from delivering temporary hospitals in cities around the world—in some instances, in a matter of days—to advising public-and private-sector clients across industries on their safe reopenings. We pioneered and rolled out virtual consultation tools and digital plat forms to help public transit systems return to ser vice and to advance other infrastructure projects critical to economic and social recover y. To that end, in my new role as chief executive officer, I have moved quickly along with the leadership team to prioritize investments of capital and time to ensure we are delivering on our commitment to set a new standard of excellence in our industr y. This includes actions we have taken to restructure the business and simplif y the organization to remove layers and enhance collaboration. We have I

FY20 Highlights 14% Adjusted1 EBITDA2 growth $341 Free cash flow3 (millions) 13% Increase in project backlog $2.15 Adjusted1 earnings per share 23% FY21 adjusted earnings per share growth (mid-point of guidance) With more than 90% of our 54,000 employees working remotely at peak, we leveraged technology to engage our clients and keep our teams productive. Our Fast Forward to the Future initiative builds upon this experience, our people’s ingenuity and new technology to improve our efficiency and forever change how we work and deliver for our clients. • In FY20, our adjusted1 earnings per share (EPS) increased from $1.86 to $2.15, and we have set guidance for FY21 in the range of $2.55 to $2.75—a 23% increase at the midpoint. Recognizing that promoting diversit y in ideas and perspectives makes us a better, more innovative company, AECOM reaffirmed its commitment to extending a culture of equity, diversity and inclusion (ED&I) throughout our global enterprise. From creating a reverse mentoring program pairing more junior professionals with our executive leadership team to expanding employee resource groups, we continue to ensure AECOM remains a place where our diverse talent thrives with equitable opportunities to grow, deliver superior business results and enrich our communities. As a reflection of the strength of our global brand and reputation for integrity, AECOM was named one of Fortune’s World’s Most Admired Companies for a sixth consecutive year, and we were again ranked the number one design firm by Engineering News-Record in 2020 in many markets, including transportation, environment and facilities. Reinforcing the strength of our business In fiscal year 2020, we improved our underlying business and delivered on our f inancial commitments in the following ways: Setting a new course for the future Working with an engaged Board of Directors and senior leadership team, we have put for ward a new strategic approach to help carry us through the pandemic and best address the evolving challenges faced by our clients and a warming planet. • Achieved 14% adjusted1 EBITDA2 growth, marking a new high for our Professional Services business, and $341 million of free cash flow3 for the year. • Expanded our project backlog by 13%, near an all-time high, providing us with visibility to execute with certainty. Central to our strategy is my belief, informed by my long time spent in Professional Ser vices organizations, that our people are at the hear t of our company. They distinguish us in the marketplace and define AECOM as the innovative, go-to consultants for our clients’ most challenging projects. Through ever y decision we make, our leadership team must be focused on creating value for our employees—and, in turn, creating value for our clients and shareholders. • Fur ther simplified our business and reduced risk by completing the $2.4 billion sale of our Management Ser vices group and closing on the divestiture of the Power construction and Civil construction businesses early in fiscal 2021. • Extended shareholder value by delivering industry-leading adjusted operating margins, de-risking our business profile and strengthening our balance sheet. We executed on our capital allocation policy with more than $500 million of share repurchases bet ween September and December 2020, and our Board of Directors increased the authorization for purchases from $305 million to $1 billion. II

“At AECOM, we are optimistic about the future and continue to work toward a world where infrastructure creates opportunity for everyone.” As you’ll read in the pages that follow, our Think and Act Globally strategy is designed to advance our growth and create value in four ways: Our bright future is the result of our transformation into a Professional Ser vices firm. We have reduced risk in our business portfolio and made investments in people and digital innovations to expand our market share in transportation, water, facilities and the environment, and to deepen client engagement. A simplified operating model that leverages an expanded network of global design centers improves our efficiency, while standardizing high quality and allowing us to accelerate client delivery. THINK AND ACT GLOBALLY 1. Simplifying our organization and focusing our global capabilities in markets that better play to our core strengths. Key among these changes was the global integration of our Design and Consulting Services (DCS) business. The ability to draw on diverse, global perspectives from our industry’s most talented workforce will continue to be a competitive advantage for AECOM, and the collaboration among our professionals that is reinforced by our Think and Act Globally strategy allows us to bring our global expertise to each client and power new ideas. 2. Deepening our client relationships and the knowledge-based solutions we provide to capitalize on new opportunities. The changes we have made and our path forward, are already creating shareholder value, with our stock performance in fiscal year 2020, up nearly 20%, surpassing the average percentage gains of our peers and the S&P 500. We have built a cash-generative, enduring business model with the agilit y and resiliency to overcome uncer tainties arising from the pandemic and better pursue emerging opportunities. 3. Continuing to transform how we work to expand flexibility for our employees and clients, significantly improve productivity, advance technical excellence and increase client satisfaction. At AECOM, we are optimistic about the future and continue to work toward a world where infrastructure creates opportunity for everyone. We hope to know soon whether new vaccines and public health vigilance can bring an end to this pandemic, but the work of recovering from this global tragedy is already beginning. 4. Leading our industry in ESG to help our clients better prioritize and respond to environmental and net-zero mandates, and to support projects and programs that uplift communities and create positive social impact. No mat ter the challenges we may face on this journey together, AECOM is better positioned for success today than ever before in our histor y, and our teams are passionately aligned in purpose to deliver a better world. Troy Rudd Chief Executive Officer III

Delivering a better world in which people and communities grow IV

WORK HIGHLIGHT S 2020 was a year like no other, and the COVID-19 pandemic had profound impacts on the daily lives of our employees and their families, our clients, our communities and our business. Our employees’ safety, health and well-being are our top priority. As soon as the pandemic began, we took immediate action to ensure they were safe and accounted for, and to maintain business continuit y for our clients. In each of our markets, we have been doing our part to help contain the spread of COVID-19 and enable a safe work environment by following the lead of our safety and health experts, as well as guidance from public health organizations and government agencies. We also changed the way we work , with more than 90% of our employees working remotely at peak while improving client satisfaction. The pandemic intensif ied the pace of digital transformation and has magnif ied the benef its of our long-standing investments in IT and innovation, including the development and release of cut ting-edge solutions to help deepen engagement bet ween our employees and our clients as well as our clients and their stakeholders. Through it all, our organization has come together in new ways to deliver for our clients and continue realizing our purpose to deliver a better world. From t he earliest days of t he out break , our professionals mobilized quickly to provide extraordinar y support for our clients and communities during these challenging times. Working closely with federal, state and local clients, our teams led the industr y for disaster response, including delivering temporar y hospitals with thousands of hospital beds and advising clients on their safe reopening and return-to-work strategies. >90 % Remote workforce at peak of pandemic V

R APID RESPONSE We quickly activated our disaster resilience teams to help federal, state and local clients expand healthcare capacity in the first months of the pandemic. AECOM provided design, engineering, consultancy, construction management and project management services to assess and modify existing facilities, and design and build new temporary hospitals, alternate care facilities and testing locations. >1,000 >1,000 >400 >1,000 State University of New York at Old Westbury, Long Island, New York • Expanded new alternate care facility capacity by 1,024 beds • Delivered U.S. Army Corps of Engineers project in 28 days in support of a FEMA mission assignment New York City Department of Design and Construction, Brooklyn and Queens, New York • Mobilized teams to manage construction of both hospitals within 24 hours of award • Increased the cit y ’s hospital capacit y by more than 1,000 beds The Ranch Events Complex, Loveland, Colorado • Delivered a temporary health-care facility with nearly 200 operational patient beds as well as an additional 200 patient beds with minimal build-out for future surge capacity McCormick Place Convention Center, Chicago, Illinois • Delivered 1,000 beds for the McCormick Place alternate care facility VI

Leading the way with sustainable solutions SUSTAIN A BILIT Y As a Professional Services firm, it is important that we lead in environmental, social and governance (ESG) issues, particularly as we acknowledge the biggest impact we can have is by providing sustainable support and advice to clients. With more than 54,000 employees around the world, we have a significant opportunity—and responsibility—to not only lessen the impact of our work, but also to protect, enhance and restore the natural and social systems upon which we rely, including as part of our continued contribution to the United Nations Sustainable Development Goals. This is why leading in ESG is a core element of our Think and Act Globally strategy, ensuring we encourage clients to join us on the sustainability journey to create a greener, healthier, more equitable planet. A key aspect of our ESG strategy is our climate change response. We do not limit our thinking on emissions reductions simply to environmental issues. We also consider the vast impacts climate change can and will have on all the communities we ser ve, especially on people dispropor tionately af fected who live in vulnerable areas. In response, we have set approved science-based targets in alignment with the Paris Agreement and targeted at preventing the worst impacts of climate change, with a 2025 deadline against a 2018 baseline: 2025 Science-Based Targets 20% Reduction in scope 1 and 2 emissions (fleet vehicles and office energy) 10% Reduction in supply chain emissions (scope 3) VIII

We are proud of the progress we have made thus far since setting our approved targets early in 2020. At the end of the fiscal year, we achieved a 24% reduction in our Scope 1 and 2 emissions and a 5% reduction in supply chain emissions compared to FY18, meaning we have early achievement of our Scope 1 and 2 target in this unique year and are on track to achieve our supply chain target on schedule. These results show a consistent effort to improve efficiency in our business, and we are constantly looking to improve our data quality and emissions performance. Scope FY18 (baseline) FY20 24% Reduction in Scope 1 and 2 emissions (versus FY18) 5% Reduction in supply chain emissions (versus FY18) Scope 1 & 2 (MT CO2e) 147,509 112,340 Supply chain (Scope 3) (MT CO2e) 6,061,065 5,734,285 Total (MT CO2e) 6,208,574 5,846,625 We continue to advance plans to create further efficiency in our operations and reduce our emissions, including increasing the amount of green energy used for our offices and implementing our Workplace of the Future initiative to further consolidate our real estate and reduce travel. Across our global real estate por t folio, we are refurbishing of f ice spaces to create collaborative, innovative, low energy-related emissions working environments. These refurbishments are part of a low-emissions feasibility study that will scale up best practices and successes across all of our offices around the world. We are also looking closely at our supply chain emissions to identif y hotspots, integrate sustainabilit y into our procurement processes and work with our key suppliers to decarbonize in line with the Paris Agreement . Our latest Carbon Disclosure Project (CDP) climate change response scored above the industr y average. We also continue our commitment to addressing climate risk as par t of business strategy through disclosing our climate -related risks and oppor tunities. IX

SUSTAIN A BILIT Y PRO JECT S SPOTLIGHT Helping to deliver clients’ net zero ambitions NE T WORK R AIL, UNITED K INGDOM AECOM is a trusted partner of Network Rail, providing sustainability ser vices on its path to net-zero carbon, which includes three levels: strategic planning, tactical inter vention identification and project implementation. The strategy includes a framework and a roadmap to 2050 that address economic, social and environmental sustainability issues. AECOM mobilized a team of Network Rail carbon champions who have identified savings of 14% in energy focusing on replacing gas for heating, more efficient lighting and cooling, and the transition to alternative fuels for fleet vehicles. 14 Savings in Energy % This three-level engagement enables AECOM to deliver the energy reduction and zero-carbon plans in a coordinated fashion, delivering zero-carbon energy infrastructure in parallel with the confirmation of the completed pathway to net zero. X “As leaders in our industry focused on ESG priorities, we have a culture that is committed to building a better world and helping clients advance more sustainable solutions—from developing and implementing energy efficiency and savings programs to managing the construction of LEED Platinum buildings and creating proprietary solutions for the cleanup of PFAS and other emerging contaminants.” Lara Poloni President

Strengthening climate resilience CIT Y OF DALL A S ENVIRONMENTAL & CLIM ATE ACTION PL AN The City of Dallas commissioned AECOM to develop the city’s first-ever Comprehensive Environmental and Climate Action Plan (CECAP) to implement the mayor’s commitment to support the Paris Agreement. Unanimously adopted in May 2020, the CECAP includes a comprehensive roadmap that outlines the specific activities the city can undertake to reduce greenhouse gas emissions, improve environmental quality and strengthen climate resilience in the city. Leveraging insights gained from AECOM’s proprietary Climate action for URBan sustainability (CURB) tool, the plan received wide support from environmental justice communities, environmental advocates, public health authorities, and education and business organizations. Achieving carbon neutrality 80 ANN STREE T, BRISBANE, AUSTR ALI A AECOM is designing 80 Ann Street, a 75,000-square-meter, 32-story commercial tower located in Brisbane, Australia, which features a new cross-block public laneway with retail tenancies, connecting Ann Street to Turbot Street through the heritage Brisbane Fruit and Produce Market building. The proposed development has been designed to meet numerous sustainability certifications and ratings, including the highest NABERS and WELL certifications, and achieve carbon neutrality through full electrification and power purchase agreements for renewable energy.

AECOM has been recognized globally for delivering projects that reflect our commitment to leading in environmental, social & governance (ESG) issues. We have received awards that commend our work in areas such as energy-efficient design, management of flood and coastal risk, sustainable solutions and outstanding environmental management. SUSTAIN A BILIT Y AWARDS The Te Auaunga Awa (Oakley Creek) flood mitigation project in New Zealand won the Morphum Environment & Sustainability Excellence Award. Initially intended to reduce flooding and allow for higher-density affordable housing in the area, this project is an example of collaboration and engineering excellence that led to a range of positive environmental, social, cultural and economic impacts. The Clatterbridge Cancer Centre in Liverpool, which opened earlier this year, was named Subregional Project of the Year (Liverpool) at the 2020 North West Construction Awards. AECOM’s role in the project was to design an energy-efficient building through the provision of multidisciplinar y ser vices, including building ser vices engineering, civil and structural engineering, acoustic engineering, sustainability and BREEAM and environmental ser vices. Our designs for the Bay Bridge Pedestrian Piers received an award from the Northern California American Society of Landscape Architecture in the General Design category. This transformative project upcycled the old Bay Bridge foundations and salvaged bridge steel to create new pedestrian piers in Oakland and San Francisco. An opportunity was identified to repurpose funds that would have been used to implode the old bridge structures to instead build public access platforms for recreation in disadvantaged communities. AECOM’s landscape architecture team led the design and implementation. Design, permitting and construction was completed in less than a year and a half — extremely fast for waterfront construction. S AFE T Y AWARDS AECOM has been commended by clients and councils with numerous safety awards across the globe over the course of FY2020, including: From the United States National Safety Council (NSC) alone, AECOM received 157 awards, including: 155 Perfect Record Awards Achieved a minimum of 12 consecutive months without a recordable injur y or illness 2020 Ground Investigation Project of the Year Awarded to Structural Soils working with Highways England and AECOM 2 Million Work Hours Awards Achieved a minimum of one million consecutive hours without an injur y or illness that resulted in days away from work and zero fatalities 2020 Health and Safety Award Recognizing AECOM and Equipe Training’s safety initiative to ensure plant and rig conformity/compliance on the Lower Thames Crossing project In addition, hundreds of AECOM super visors earned Safety Qualified Super visor status, demonstrating their commitment to our values and their outstanding leadership abilities XII

Safeguarding our people remains a core value at AECOM, and our focus on safety was never more apparent than in fiscal 2020. S AFE T Y Over the course of the year, our Total Recordable Incident Rate improved by 31% over the prior year to 0.11, and our Lost Workday Case Rate improved by 40% to 0.03. Both of these metrics reflect a world-class level of safety performance and are at an industry-leading level. Total Recordable Incident Rate (TRIR) Lost Workday Case Rate (LWCR) 31% 40% Our focus on safety extends beyond our strong performance on these lagging indicators. We recognize that in order to ensure the continued safety of our teams, we need to ensure that we continue to take proactive steps to train our professionals, investigate and manage near-miss incidents and provide readily-available avenues for identifying potential safety concerns and suggesting improvements. As a result, we are also pleased that we exceeded our targets for our internal leading indicators for these initiatives. Throughout all of these initiatives, our commitment to safeguarding our people has been paramount in our response to the global Coronavirus pandemic. Our pandemic preparedness and resiliency processes have been further developed through cross-functional collaboration to protect the safety and well-being of personnel, protect the environment and maintain business continuity, given existing and potential Coronavirus impacts. This includes key resources and tools that continue to facilitate workplace readiness activities, address challenges of new working environments (e.g., ergonomic awareness in working from home), support well-being and manage potential Coronavirus exposure. We are continually monitoring our safety performance to ensure that we meet our clients’ SH&E expectations. We have established dedicated SH&E leads for each of our key accounts and ensure participation in all required client-specific training programs, often jointly facilitated between AECOM and the client.

Executive Compensation Practices

Our executive pay program provides competitive pay packages that attract, motivate, reward and retain key talent critical to achieving long-term strategic objectives, our ongoing commitment to sustainability, diversity, and inclusion, and the creation of leading shareholder value. Our executive pay program is strongly aligned with stakeholder value and promotes AECOM's ESG (Environmental, Social and Governance) and EDI (Equity, Diversity and Inclusion) initiatives.

What We Do:
​
✓ Pay-for-Performance — We condition a majority of performance compensation for our Named Executive Officers (NEOs) on the achievement of earnings, cash flow, Return On Invested Capital ("ROIC") targets, and Relative Total Shareholder Return ("TSR").
​
✓ Rigorous Goal Setting — We undergo a detailed process of analyzing and reviewing a number of factors including but not limited to our short- and long-term financial plan; investor input, feedback and expectations; industry and peer performance; benchmarking; and overall achievability.
​
✓ Stockholder Engagement — We engage with stockholders throughout the year, including direct outreach to stockholders that represent the ownership of more than 50% of our stock.
​
✓ Stock Ownership Guidelines — We have stock ownership guidelines that require NEOs to maintain a significant equity stake in the Company. The CEO ownership guideline is six times base salary and the guideline for other NEOs is three times base salary.
​
✓ Independent Consultant — We utilize the services of an independent compensation consultant who does not provide any other services to the Company.
​
✓ Clawback Policy — We maintain a clawback policy that allows us to recoup a portion of the short-term cash and long-term equity incentive-based compensation awards paid to current and former officers who are subject to reporting under Section 16 of the Exchange Act (referred to below as Section 16 officers) during the three fiscal years before an accounting restatement due to material noncompliance with any financial reporting requirement under the securities laws.
​
✓ Risk Assessment — Our compensation consultant performs an independent risk assessment of compensation programs.
​
✓ Competitive Analysis — We annually seek to understand labor market trends pertaining to the amount and form of executive pay delivery through comprehensive competitive analyses.
​
✓ Annual Say-on-Pay Vote — We have a policy to hold an advisory vote to approve the Company's executive compensation on an annual basis.
​
What We Don't Do:
​
✘ Stock Option Repricing — Our stock plan prohibits re-pricing underwater stock options or stock appreciation rights without stockholder approval.
​
✘ Single Trigger Equity Acceleration — We do not maintain plans or agreements that provide for automatic "single-trigger" equity acceleration or bonus payments in connection with a change in control (rather, any payment of benefit requires a qualifying termination of employment in connection with a change in control known as "double trigger").
​
✘ Tax Gross-Ups — We do not provide tax gross-ups to NEOs on change in control payments.
​
✘ Hedging and Pledging — We prohibit hedging transactions involving AECOM common stock and do not allow trading in puts, calls, options or other similar transactions. In addition, we prohibit the pledging of AECOM common stock except in certain limited circumstances subject to Company approval and demonstration of the ability to repay the applicable loan without selling such securities.

Environmental, Social and Governance Matters

We are committed to being a leader in environmental sustainability, social responsibility, and corporate governance.

We embrace sustainability by striving to make a positive, lasting impact on society and the environment. Sustainability and resilience in the world's built and natural environments are at the core of what we do and how we operate — focusing on the environmental, social and governance impacts of our business. Through our projects and our operations, we have both a significant opportunity and a responsibility to protect, enhance and restore the world's natural and social systems.

We are committed to addressing the effects of climate change as a key priority for our sustainability program by improving resilience and working to advance ambitious greenhouse gas emissions reduction targets. Having achieved our previous emissions reduction targets ahead of schedule, we have set new science-based targets for 2025 that are in alignment with the Paris Agreement's goals to limit the worst effects of climate change: a 20% reduction in Scope 1 and 2 emissions and a 10% reduction in supply chain emissions from our 2018 baseline. Our new targets have been independently validated by the Science Based Targets initiative (SBTi) and, at the time of validation, AECOM was the first and only US-based company in the engineering and construction sector to have set SBTi targets. |  |

In addition, we continue to invest in proprietary innovations and solutions to combat globally pervasive emerging contaminants, such as our patented DE-FLUOROTM water treatment solution to destroy per- and polyfluoroalkyl substances (PFAS) on-site.

We have established an internal Global ESG Council to coordinate and drive our ESG initiatives across AECOM worldwide. The Council's functions include: (i) assessing the impact of the Company's services and operations and advising on how the Company may enhance its ESG performance; (ii) advising on appropriate global ESG goals, commitments and targets; (iii) shaping the Company's ESG messaging and disclosure; and (iv) assessing the potential impact of climate change on the Company's services and operations and providing a global forum to share ideas on how the Company's unique offerings and solutions can enable mitigation, adaptation and resilience to climate change that will develop and support buildings, infrastructure assets and communities; and (v) providing a framework for evaluating client opportunities to ensure that they align with our ESG goals. The Council is composed of employees with relevant professional expertise and experience including strategic and end market leadership; consulting expertise; operations; procurement, real estate and facilities management and other corporate functions. Our Board, including through its Safety, Risk and Sustainability Committee, has oversight over ESG matters. Additional information regarding our ESG initiatives is located on the investor relations section of our website, at https://investors.aecom.com/esg.

Commitment to Our People (Human Capital Management)

We have made key advances in the past year in our transformation into a professional services firm and continue to set new standards for excellence in our industry.

This understanding informs our approach to supporting our people.

Our principal asset is our employees, and large percentages of our employees have technical and professional backgrounds and undergraduate and/or advanced degrees. At the end of our fiscal 2020, we employed

We are committed to engaging our employees globally to understand regional inclusion and diversity opportunities, building leadership accountability and expanding recruitment efforts to foster a workforce reflective of our communities. To continue attracting and retaining some of the most talented employees in our industry, we ensure employees have the tools and resources they need to hone their skills, develop strong leadership behaviors and advance their careers. Our human capital objectives and initiatives are overseen by our Board as per our Corporate Governance Guidelines.

Health and Safety. Core to our corporate values is safeguarding our people and fostering a culture of caring that promotes the wellbeing of our employees, contractors and business partners. We safeguard our people, projects and reputation by striving for zero employee injuries and illnesses, while operating and delivering our work responsibly and sustainably. We maintain our industry's best-in-class lost workday case and recordable incident rates, and our safety performance is consistently recognized by key clients across the regions where we work as well as by recognized safety organizations.

|  | From the United States National Safety Council (NSC) alone, AECOM received 157 awards, including: • Perfect Record Awards (155): Achieved a minimum of 12 consecutive months without a recordable injury or illness. • Million Work Hour Awards (2): Achieved a minimum of one million consecutive hours without an injury or illness that resulted in days away from work and zero fatalities. In addition, hundreds of AECOM supervisors earned Safety Qualified Supervisor status, demonstrating commitment to our values and outstanding leadership abilities.

Equity, diversity and inclusion. While ED&I has always been a part of our culture, we continue to advance efforts globally to integrate our principles into all aspects of our work and measure results. We are focused on four key areas: 1) Building diverse talent through our recruitment efforts, as well as offering internships (including virtual internships during the Covid-19 pandemic) and partnering with nonprofit organizations and universities, 2) Enriching communities through pro-bono work, volunteerism, philanthropy and strategic partnerships, 3) Expanding understanding and empathy among employees through community-building, training and family-friendly benefit

policies, and 4) Prioritizing the social impact and benefits of ED&I into every project we pursue and the innovative solutions we deliver.

Employee experience. We continue to enhance our employee programs, workplace culture and digital technologies to support employees and managers in more effective and efficient ways to execute their work and meaningfully engage with clients. These efforts include employee wellness and wellbeing programs to better support employees while working remotely during the Covid-19 pandemic and beyond, expanding access and technical training programs through our online education portal, AECOM University, delivering new digital tools to boost connectivity among employees, and advancing frontline leadership programs.

Workplace of the Future Initiative. Drawing upon the experiences of our professionals, who have remained highly productive while working remotely during the Covid-19 pandemic, we have invited their input and ideas to begin to shape the future ways of working at AECOM. In particular, through a global competition, we challenged our professionals to consider how new workspaces can support health, collaboration and camaraderie, how technology and tools can be leveraged to ensure continuing productivity and client engagement, and what they need to be well and engaged. Many of the resulting ideas are being implemented regionally and globally. Our initiatives in this area include a continued drive toward digital delivery of our work product and enhanced client engagement, hybrid work environments, and a repurposed and overall reduced global real estate footprint.

Community responsibility. Through strategic nonprofit partnerships, pro-bono work, skills-based volunteering and philanthropy, Blueprint for a Better World, our corporate responsibility platform, is focused on delivering access to safe and secure infrastructure to those who need it most, creating opportunity for the leaders of tomorrow and protecting our planet so that our company can fulfill its purpose to deliver a better world. As part of the Blueprint pro-bono program, our technical experts partnered with nonprofit organizations in their local communities to provide critical design, engineering and infrastructure solutions. In fiscal 2020, we continued to further our employees' passion through the Blueprint Travel Grant program, which included building dormitories to further Peruvian girls' education, purifying drinking water on the Zinga Islands of Uganda, strengthening engineering ecosystems in Sub-Saharan Africa, and designing and fundraising for a women and children's center in Kosovo. In addition, we sustained our commitment to our enterprise strategic nonprofit partners — Engineers Without Borders and Water for People.

PROXY STATEMENT
ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD
FEBRUARY 24, 2021

INTRODUCTION

This Proxy Statement is furnished in connection with the solicitation of proxies, on behalf of the Board of Directors of AECOM, a Delaware corporation ("we," "our," the "Company" or "AECOM"), for use at our 2021 Annual Meeting of Stockholders ("2021 Annual Meeting") to be held on February 24, 2021, at 8:00 a.m. Pacific Time, or at any adjournment or postponement thereof. At the 2021 Annual Meeting, you will be asked to consider and vote on the matters described in this Proxy Statement and in the accompanying notice. The 2021 Annual Meeting will be held virtually on the Internet. You will be able to attend the annual meeting, vote, and submit questions during the meeting by visiting www.meetingcenter.io/276990237. Only common stockholders of record at the close of business on January 11, 2021, which is the record date for the 2021 Annual Meeting, are permitted to vote at the 2021 Annual Meeting and any adjournment or postponement thereof.

The Company's Board of Directors (the "Board of Directors" or "Board") is soliciting your vote to:

1.
  Elect each of the 11 director nominees named in this Proxy Statement to the Company's Board of Directors to serve until the Company's 2022 Annual Meeting of Stockholders.
2.
  Ratify the selection of Ernst & Young LLP as our independent registered public accounting firm for Fiscal Year 2021.
3.
  Approve the Company's executive compensation, on an advisory basis.
4.
  Consider and act upon a stockholder proposal regarding lobbying disclosure.

We utilize the U.S. Securities and Exchange Commission rule allowing companies to furnish proxy materials to their stockholders over the Internet. We believe that this e-proxy process expedites stockholders' receipt of proxy materials while also lowering the costs and reducing the environmental impact of our annual meeting. On January 15, 2021, we began mailing a Notice of Internet Availability of Proxy Materials (the "Notice") to all stockholders of record as of January 11, 2021, and posted our proxy materials on the website referenced in the Notice. As more fully described in the Notice, all stockholders may choose to access our proxy materials on the website referred to in the Notice or may request a printed set of our proxy materials. In addition, the Notice and website provide information regarding how you may request proxy materials in printed form by mail or electronically by e-mail on an ongoing basis.

The Notice of Internet Availability of Proxy Materials, Proxy Statement and our Annual Report on Form 10-K are available at investors.aecom.com.

ANNUAL MEETING INFORMATION

Proxies

You may vote your shares at the 2021 Annual Meeting or by proxy if you are a record holder. There are three ways to vote by proxy: (1) on the Internet by following the instructions on the Notice or proxy card, (2) by telephone by calling 1-800-652-8683 and following the instructions on the Notice or proxy card or (3) by requesting a printed copy of the proxy materials and signing, dating and mailing the enclosed proxy card to our Corporate Secretary at the address below. If your shares are held in the name of a bank, broker or another holder of record, you will receive instructions from the holder of record. You must follow the instructions of the holder of record in order for your shares to be voted. Internet and telephone voting will also be offered to stockholders owning shares through certain banks and brokers.

You may revoke your proxy at any time before it is exercised at the 2021 Annual Meeting by (1) giving our Corporate Secretary written notice of revocation, (2) delivering to us a signed proxy card with a later date, (3) granting a subsequent proxy through the Internet or telephone or (4) attending the 2021 Annual Meeting and voting. Written notices of revocation and other communications with respect to the revocation of proxies should be addressed to AECOM, 300 South Grand Avenue, 9th Floor, Los Angeles, California 90071, Attention: Corporate Secretary.

All shares represented by valid proxies received and not revoked before they are exercised will be voted in the manner specified in the proxy. Other than with respect to certain trustees who hold our shares in trust, if you submit proxy voting instructions but do not direct how to vote on each item, the persons named as proxies will vote in accordance with the Board recommendations for the proposals. Our Board is unaware of any matters other than those described in this Proxy Statement that may be presented for action at our 2021 Annual Meeting. If other matters do properly come before our 2021 Annual Meeting, however, it is intended that shares represented by proxies will be voted in the discretion of the proxy holders.

If you are a beneficial owner and hold your shares in the name of a bank, broker or another holder of record and do not return the voting instruction card, the broker or another nominee may vote your shares on each matter at the 2021 Annual Meeting for which he or she has the requisite discretionary authority. Under applicable rules, brokers have the discretion to vote on routine matters, which include the ratification of the selection of the independent registered public accounting firm. Brokers will not have the discretion to vote on any of the other proposals presented at the 2021 Annual Meeting.

Solicitation of Proxies

We will pay the entire cost of soliciting proxies. In addition to soliciting proxies by mail and by the Internet, we will request banks, brokers and other record holders to send proxies and proxy materials to the beneficial owners of our common stock and to secure their voting instructions, if necessary. We will reimburse record holders for their reasonable expenses in performing these tasks. We have agreed to pay Innisfree M&A Incorporated $25,000 plus reasonable expenses, costs and disbursements for various proxy solicitation services associated with the 2021 Annual Meeting. If necessary, we may use our regular employees, who will not be specially compensated, to solicit proxies from stockholders, whether personally or by telephone, letter or other means.

Record Date and Voting Rights

Our Board has fixed January 11, 2021 as the record date for determining the stockholders who are entitled to notice of, and to vote at, our 2021 Annual Meeting. Only common stockholders of record at the close of business on the record date will receive notice of, and be able to vote at, our 2021 Annual Meeting. As of the record date, there were 147,774,517 shares of our common stock outstanding held by 1,808 record holders. A majority of the stock issued and outstanding and entitled to vote must be present at our 2021 Annual Meeting, either in person or by proxy, in order for there to be a quorum at the meeting. Each share of our outstanding common stock entitles its holder to one vote. Shares of our common stock with respect to which the holders are present at our 2021 Annual Meeting but not voting, and shares for which we have received proxies but with respect to which holders of the shares have abstained, will be counted as present at our 2021 Annual Meeting for the purpose of determining whether or not a quorum exists. "Broker non-votes" will also be counted as present for the purpose of determining whether a quorum exists. Broker non-votes are shares of common stock held by brokers or nominees over which the broker or nominee lacks discretionary power to vote and for which the broker or nominee has not received specific voting instructions from the beneficial owner.

Our Board urges you to vote promptly by either (1) electronically submitting a proxy or voting instruction card over the Internet, (2) by telephone or (3) by delivering to us or to your broker, as applicable, a signed and dated proxy card.

Votes will be tabulated by the inspector of election appointed for the 2021 Annual Meeting, who will separately tabulate affirmative and negative votes, abstentions and broker non-votes.

Year End Reporting Convention

We report our results of operations based on 52- or 53-week periods ending on the Friday nearest September 30. For clarity of presentation, all periods are presented as if the fiscal year ended on September 30. Fiscal 2020 consisted of a 53-week period.

Majority Voting; Director Resignation Policy

In uncontested elections, directors will be elected by a majority of the votes cast, which means that the number of shares voted "for" a director must exceed the number of shares voted "against" that director. In uncontested elections, any director who is not elected by a majority of the votes is expected to tender his or her resignation to the Nominating and Governance Committee ("Nominating Committee"). The Nominating Committee will recommend to the Board whether to accept or reject the resignation offer, or whether other action should be taken. The Board will act on the Nominating Committee's recommendation within 90 days following certification of the election results.

PROPOSAL 1
ELECTION OF DIRECTORS

We are nominating 11 directors for election to our Board, 9 of whom are current members of our Board that are standing for re-election at the 2021 Annual Meeting. Directors elected at the 2021 Annual Meeting will serve until the 2022 Annual Meeting of Stockholders and until their successors are duly elected and qualified. If a quorum is present at our 2021 Annual Meeting, the directors will be elected by a majority of the votes cast, which means that the number of shares voted "for" a director must exceed the number of shares voted "against" that director, with any director who is not elected by a majority of the votes case being expected to tender his or her resignation to the Nominating Committee. The Nominating Committee will recommend to the Board whether to accept or reject the resignation offer, or whether other action should be taken. The Board will act on the Nominating Committee's recommendation within 90 days following certification of the election results.

Shares represented by proxies will be voted, if authority to do so is not withheld, for the election of each of the director nominees named in this Proxy Statement. The size of our Board is currently 11 directors, and we are nominating 11 director nominees. Proxies cannot be voted for a greater number of persons than the number of nominees named. Each of the nominees has consented to serve as a director if elected, and management has no reason to believe that any nominee will be unable or unwilling to serve if elected as a director, except as set forth in the remainder of this paragraph. In the event that any nominee is unavailable for re-election as a result of an unexpected occurrence, shares will be voted for the election of such substitute nominee as our Board may propose.

Director Qualifications

The Board believes that, as a whole, Board members should possess a combination of the skills, professional experience and diversity of backgrounds necessary to oversee the Company's business. The Nominating Committee is responsible for developing and recommending Board membership criteria to the full Board for approval. The criteria, which are set forth in the Company's Corporate Governance Guidelines, include the highest professional and personal ethics and values, commitment to enhancing stockholder value with sufficient time to effectively carry out his or her duties and business acumen. In considering director candidates, the Nominating Committee looks for business experience and skills, judgment, integrity, an understanding of such areas as finance, marketing, regulation and public policy and the absence of potential conflicts with the Company's interests. In particular, the Nominating Committee seeks candidates that have skills/experience in the following areas, each of which it is views as particularly important: senior leadership experience, industry experience, public company experience, financial expertise, government/regulatory expertise and international expertise. The Nominating Committee believes that it is essential that Board members represent diverse viewpoints and backgrounds.

The Nominating Committee periodically reviews the appropriate skills and characteristics required of Board members in the context of the current composition of the Board, the operating requirements of the Company and the long-term interests of the Company's stockholders. In conducting this assessment, the Nominating Committee considers diversity, skills and such other factors as it deems appropriate to maintain a balance of knowledge, experience and capabilities. This periodic assessment enables the Board to update the skills and experience it seeks in the Board, as a whole and in individual directors, as the Company's needs evolve over time and to assess the effectiveness of efforts at pursuing diversity. From time to time, while identifying director candidates, the Nominating Committee may establish specific skills and experience that it believes the Company should seek in order to constitute a balanced and effective Board.

Vote Required and Recommendation of the Board of Directors

Directors are elected by a majority of the votes cast for and against by holders of shares entitled to vote at the 2021 Annual Meeting. This means that for each director the number of votes cast "FOR" the director must exceed the number of votes cast "AGAINST" the director. Abstentions and broker non-votes will not be considered votes cast.

The Board of Directors recommends that you vote FOR the election of each nominee for director.

PROPOSAL 2
RATIFICATION OF SELECTION OF INDEPENDENT
REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of our Board has retained Ernst & Young LLP to serve as our independent registered public accounting firm for the fiscal year ending September 30, 2021. Ernst & Young LLP has served as the Company's independent registered public accounting firm since 1990. A representative of Ernst & Young LLP is expected to be present at the 2021 Annual Meeting and will have an opportunity to make a statement if the representative so desires, and will be available to respond to appropriate questions.

Reasons for the Proposal

The selection of our independent registered public accounting firm is not required to be submitted for stockholder approval, but the Audit Committee of our Board is seeking ratification of its selection of Ernst & Young LLP from our stockholders as a matter of good corporate practice. If stockholders do not ratify this selection, the Audit Committee of our Board will reconsider its selection of Ernst & Young LLP and will, in its sole discretion, either continue to retain this firm or appoint a new independent registered public accounting firm. Even if the selection is ratified, the Audit Committee may, in its discretion, appoint a different independent registered public accounting firm at any time during the fiscal year if it determines that such a change would be in the Company's best interests and the best interests of our stockholders.

Reasons for Recommendation to Appoint Ernst & Young as the Company's Independent Registered Public Accounting Firm

As with previous years, the Audit Committee undertook a review of Ernst & Young LLP in determining whether to select Ernst & Young LLP as the Company's independent registered public accounting firm for fiscal year 2020 and to recommend ratification of its selection to the Company's stockholders. In that review, the Audit Committee considered a number of factors including:

•
  continued independence of Ernst & Young LLP;
•
  length of time Ernst & Young LLP has been engaged by the Company;
•
  senior management's assessment of Ernst & Young LLP's performance;
•
  audit and non-audit fees;
•
  capacity to appropriately staff the audit;
•
  geographic and subject matter coverage;
•
  lead audit engagement partner performance;
•
  overall performance;
•
  qualifications and quality control procedures; and
•
  whether retaining Ernst & Young LLP is in the best interests of the Company and its stockholders.

Based upon this review, the Audit Committee believes that Ernst & Young LLP is independent and that it is in the best interests of the Company and our stockholders to retain Ernst & Young LLP to serve as our independent registered public accounting firm for Fiscal Year 2021.

In accordance with the Sarbanes-Oxley Act and the related SEC rules, the Audit Committee limits the number of consecutive years an individual partner may serve as the lead audit engagement partner to the Company. The

24

Table of Contents

maximum number of consecutive years of service in that capacity is five years. The current lead audit engagement partner is in his fourth year in that role.

Vote Required and Recommendation of the Board of Directors

The ratification of our independent registered public accounting firm requires the affirmative vote of the holders of a majority of the shares of common stock present or represented by proxy and entitled to vote on the proposal at the 2021 Annual Meeting. Abstentions will be counted as present and will have the effect of a vote against the proposal. Brokers have discretion to vote on the ratification of our independent registered public accounting firm and, as such, no votes on this proposal will be considered broker non-votes.

The Board of Directors recommends that you vote FOR the ratification of Ernst & Young LLP.

PROPOSAL 3
ADVISORY RESOLUTION TO APPROVE EXECUTIVE COMPENSATION

In accordance with Section 14A of the Exchange Act, we are asking our stockholders to approve, on an advisory basis, AECOM's executive compensation as reported in this Proxy Statement.

At AECOM, executive compensation plans are driven by both short- and long-term financial performance metrics that are designed to incentivize our NEOs to maximize long-term stockholder value creation. As such, based on direct stockholder feedback, AECOM's executives are incentivized via an annual cash bonus plan and the grant of certain long-term equity awards that include without limitation the following performance metrics: adjusted earnings per share, cash flow, return on invested capital, and relative total shareholder return.

We urge stockholders to read the "COMPENSATION DISCUSSION AND ANALYSIS" section in this Proxy Statement, which describes in more detail how our executive compensation policies and procedures operate and are designed to achieve our compensation objectives, as well as the "SUMMARY COMPENSATION TABLE" and related compensation tables and narrative, which provide detailed information on the compensation of our NEOs. The Compensation and Organization Committee ("Compensation Committee") and the Board believe that the policies, procedures and programs articulated in the "COMPENSATION DISCUSSION AND ANALYSIS" are effective in achieving our goals and that the compensation of our NEOs reported in this Proxy Statement has supported and contributed to the Company's success.

We are asking stockholders to approve the following advisory resolution at the 2021 Annual Meeting:

RESOLVED, that the stockholders of AECOM approve, on an advisory basis, the compensation of the Company's Named Executive Officers set forth in the Compensation Discussion and Analysis, the Summary Compensation Table and the related compensation tables and narrative in the Proxy Statement for the Company's 2021 Annual Meeting of Stockholders.

This advisory resolution, commonly referred to as a "Say-on-Pay" resolution, is non-binding on the Company, the Board and the Compensation Committee and will not be construed as overruling a decision by, nor creating nor implying any additional fiduciary duty for the Company, the Board or the Compensation Committee. However, the Board and the Compensation Committee will review and consider the voting results on this proposal when evaluating our executive compensation program. The Board has adopted a policy of providing for annual "Say-on-Pay" advisory votes. Unless the Board modifies its policy on the frequency of holding "Say-on-Pay" advisory voting, the next "Say-on-Pay" advisory vote will occur in 2022.

Vote Required and Recommendation of the Board of Directors

The affirmative vote of a majority of the shares present or represented by proxy and entitled to vote on the advisory resolution on the Company's executive compensation at the 2021 Annual Meeting is required to approve the advisory resolution on the Company's executive compensation. Abstentions will be counted as present and will have the effect of a vote against the proposal. Broker non-votes will not be counted as participating in the voting on the proposal and will therefore have no effect on the outcome of the vote on the proposal.

The Board of Directors recommends that you vote FOR the advisory resolution to approve executive compensation.

PROPOSAL 4
STOCKHOLDER PROPOSAL

Mr. John Chevedden, 2215 Nelson Avenue, No. 205 Redondo Beach, California. 90278, the beneficial owner of shares of the Company's common stock with a market value of more than $2,000, has requested that we include the following stockholder proposal and supporting statement in our proxy statement for the 2021 Annual Meeting. The stockholder proposal is required to be voted on at our Annual Meeting only if properly presented at the meeting. The Board of Directors recommends a vote AGAINST this proposal for the reasons stated in the Statement in Opposition to the Stockholder Proposal, which follows the proposal:

Proposal 4 — Lobbying Disclosure

Whereas, we believe in full disclosure of AECOM's direct and indirect lobbying activities and expenditures to assess whether AECOM's lobbying is consistent with AECOM's expressed goals and in the best interests of stockholders.

Resolved, the stockholders of AECOM request the preparation of a report, updated annually, disclosing:

1.
  Company policy and procedures governing lobbying, both direct and indirect, and grassroots lobbying communications.
2.
  Payments by AECOM used for (a) direct or indirect lobbying or (b) grassroots lobbying communications, in each case including the amount of the payment and the recipient.
3.
  AECOM's membership in and payments to any tax-exempt organization that writes and endorses model legislation.
4.
  Description of management's and the Board's decision-making process and oversight for making payments described in sections 2 and 3 above.

For purposes of this proposal, a "grassroots lobbying communication" is a communication directed to the general public that (a) refers to specific legislation or regulation, (b) reflects a view on the legislation or regulation and (c) encourages the recipient of the communication to take action with respect to the legislation or regulation. "Indirect lobbying" is lobbying engaged in by a trade association or other organization of which AECOM is a member.

Both "direct and indirect lobbying" and "grassroots lobbying communications" include efforts at the local, state and federal levels.

The report shall be presented to the Audit Committee or other relevant oversight committees and posted on AECOM's website.

Supporting Statement

As stockholders, we encourage transparency and accountability in AECOM's use of corporate funds to influence legislation and regulation. AECOM spent $12,240,000 from 2014 - 2019 on federal lobbying. This does not include state lobbying expenditures, where AECOM also lobbies but disclosure is uneven or absent. For example, AECOM spent $1,511,496 on lobbying in New York from 2011 - 2018. AECOM's lobbying on public construction projects in New York has attracted attentions,1 as has its lobbying in Florida on sewage system upgrades.2

AECOM does not disclose its memberships in, or payments to, trade associations, or the amounts used for lobbying. Trade associations spend millions annually lobbying indirectly on behalf of companies. And AECOM does not disclose memberships in tax-exempt organizations that write and endorse model legislation, such as the American Legislative Exchange Council. Absent a system of accountability, company assets could be used for objectives contrary to AECOM's long-term interests.

We believe AECOM's lack of lobbying disclosure presents reputational risks that could harm long-term value creation by AECOM, and thus we urge the Board to institute comprehensive lobbying disclosure.

Please vote yes:

Lobbying Disclosure Proposal — Proposal 4

28

Table of Contents

PROPOSAL 4
BOARD O F D IRECTORS' S TATEMENT I N O PPOSITION T O T HE S TOCKHOLDER P ROPOSAL

Our Board recommends a vote AGAINST this proposal.

The Board has considered this proposal and concluded that its adoption is unnecessary and not in the best interests of our stockholders in light of the Company's internal policies and existing disclosure regarding lobbying activities, the current public availability of much of the information requested by the proposal and the potential concerns relating to enhanced disclosures. Accordingly, the Board unanimously recommends a vote AGAINST this proposal.

AECOM participates in the U.S. political process to the benefit of its stockholders.

The Board believes it is in the best interests of our stockholders for AECOM to participate in the political process. As a global infrastructure firm, we are affected by numerous laws, regulations and policies which govern various aspects of our business. As a result, we actively review and discuss existing and upcoming policy changes and regulatory initiatives and take part in industry dialogue and lobbying efforts related to those issues that are of high importance to the Company's success and the concerns of our stakeholders. We strive to adhere to our corporate values and we constructively promote legislative and regulatory actions that further the business objectives of AECOM and the economic future of our stockholders and employees.

Like many major corporations, AECOM belongs to a number of industry associations. This involvement allows us to gain insight into core issues for the infrastructure sector as a whole and to advocate jointly for regulations that support an efficient, healthy and competitive industry. Such membership also allows us to benefit from the opportunity to share technical expertise and operational knowledge that leads to better safety, customer service and overall efficiency.

AECOM has robust policies and procedures in place to effectively oversee decisions regarding lobbying activities and expenditures.

AECOM is committed to complying with our values, our internal policies and all applicable laws when engaging in any type of lobbying or political activity. Management has developed a decision-making process regarding its lobbying activities to ensure they are strategic, prudent and compliant. A coordinated effort of the Company's Government Relations, Legal, Ethics and Compliance, and Communications Departments oversees and monitors AECOM's participation in the U.S. political process and its compliance with federal, state and local laws governing AECOM's lobbying activities and contributions (including dues and other payments to trade associations and other nonprofits engaged in public advocacy). This effort involves vetting procedures on advocates who lobby on the Company's behalf. The Company conducts several forms of training relating to lobbying, including annual training and certification regarding the Company's Code of Conduct, and specialized training for Company employees involved in the engagement of lobbyists and other advocates. In addition, the Board, including through its Nominating and Governance Committee, has oversight of the Company's general policy relating to the support of trade associations, political organizations and lobbying activities.

While trade associations do conduct lobbying on a wide range of issues, no company's membership in any association should be perceived as an endorsement of every policy that a particular association supports. AECOM's support for specific policies is identified in its own specific statements and lobbying disclosures.

AECOM already provides substantial disclosure regarding its lobbying activities.

Lobbying activities are subject to extensive governmental regulation and public disclosure requirements, and AECOM is fully committed to complying with all applicable U.S. state and federal laws governing these activities. The

29

Table of Contents

Board believes these disclosure requirements provide transparency of our lobbying activities to the general public, including our stockholders. Specifically, the Company:

•
  files quarterly reports with the U.S. House of Representatives and the U.S. Senate that disclose overall federal lobbying expenses, the specific legislative and regulatory issues that were the subject of the Company's federal lobbying efforts, the houses of Congress and federal agencies lobbied by the Company and the names of those individuals lobbying on behalf of the Company. These reports are publicly available on websites hosted by the U.S. House of Representatives and the U.S. Senate; and
•
  files regular, publicly available reports with state agencies which disclose the Company's state lobbying activities according to pertinent state laws.

Providing additional disclosure of AECOM's political contributions would not be in the best interests of the Company or our stockholders.

The expanded disclosure requested by this proposal could place AECOM at a competitive disadvantage by revealing strategies and priorities designed to protect the economic future of the Company, our stockholders and employees. Because parties with interests adverse to AECOM also participate in the political process to their business advantage, any unilateral expanded disclosure could benefit these adverse parties, while harming the interests of AECOM and our stockholders.

Additionally, requiring the Company to specifically disclose payments made to industry associations may be misleading to stockholders. Membership in these associations comes with the understanding that we may not always agree with all of the positions of the associations or other members of such groups. As a result, such disclosure is not necessarily indicative of our position on any particular issue.

Finally, in light of the fact that much of the Company's lobbying activities are publicly disclosed as required by law and as described above, assembling a separate lobbying disclosure report would not be a prudent use of the Company's human and financial resources, and accordingly would not be in the best interest of the Company or our stockholders.

For the reasons set forth above, the Board believes that the adoption of the Proposal is unnecessary, would not provide any meaningful benefit to stockholders and is not in the best interests of the Company, our stockholders or employees.

Vote Required and Recommendation of the Board of Directors

The affirmative vote of a majority of the shares present or represented by proxy and entitled to vote at the 2021 Annual Meeting is required to approve the stockholder proposal. Abstentions will be counted as present and will have the effect of a vote against the proposal. Broker non-votes will not be counted as participating in the voting on the proposal and will therefore have no effect on the outcome of the vote on the proposal.

The Board of Directors recommends that you vote AGAINST the stockholder proposal.

CORPORATE GOVERNANCE

Board Meetings

During our fiscal year ended September 30, 2020, our Board met nine times, the Audit Committee met five times, the Compensation Committee met eight times, the Nominating Committee met three times and the Safety, Risk and Sustainability Committee met three times. The Safety, Risk and Sustainability Committee was named the Strategy, Risk and Safety Committee during our fiscal year ended September 30, 2020. In November 2020, our Board renamed such Committee and modified the scope of its responsibility, as described further below under "Committees of the Board of Directors." Each incumbent director attended 100% of (except for one director who attended less than 100% and more than 75% of) the aggregate of (1) the total number of meetings of our Board and (2) the total number of meetings held by all standing committees of the Board on which he or she served during fiscal year 2020.

Director Independence

Eight of the 11 director nominees are independent directors as defined in accordance with the listing standards of the NYSE. These standards provide that a director is independent only if our Board affirmatively determines that the director has no direct or indirect material relationship with the Company. They also specify various relationships that preclude a determination of director independence. Material relationships may include commercial, industrial, consulting, legal, accounting, charitable, family and other business, professional and personal relationships.

Applying these standards, our Board, upon the recommendation of our Nominating Committee, annually reviews the independence of our directors. In its most recent review, our Board considered, among other things, the employment relationships between the Company and our directors and their families; the other specific relationships that would preclude a determination of independence under the NYSE independence rules; any affiliation of the Company's directors and their families with the Company's independent registered public accounting firm, compensation consultants, legal counsel and other consultants and advisors; any transactions with directors and members of their families that would require disclosure in this Proxy Statement under U.S. Securities and Exchange Commission ("SEC") rules regarding related party transactions; and the modest amount of our contributions to non-profit organizations of which some of our directors or members of their families are associated.

The Board determined that the following director nominees are independent as determined by the standards of the NYSE: Bradley W. Buss, Robert G. Card, Diane C. Creel, Jacqueline C. Hinman, Clarence T. Schmitz, Douglas W. Stotlar, Sander van't Noordende and General Janet C. Wolfenbarger.

Board Leadership Structure

The roles of Chairman and Chief Executive Officer were separated in August 2020 upon the appointment of W. Troy Rudd as Chief Executive Officer. At such time, Douglas W. Stotlar was appointed Chairman of the Board. Prior to such time, Michael S. Burke simultaneously held the roles of Chairman of the Board and Chief Executive Officer. James H. Fordyce served as the lead independent director until his resignation in November 2019. Mr. Fordyce was succeeded by Steven A. Kandarian, who served as the lead independent director until Mr. Stotlar was appointed Chairman of the Board in August 2020.

The Board has been, and continues to be, a proponent of Board independence. The Company's corporate governance structures and practices provide for a strong, independent Board and include several independent oversight mechanisms, including only independent directors serving as committee chairs and the directors' and committees' ability to engage independent consultants and advisors. The Audit, Compensation and Nominating Committees are composed entirely of independent directors.

31

Table of Contents

Executive Sessions

Executive sessions of non-employee directors are included on the agenda for every regularly scheduled Board meeting and, during fiscal year 2020, executive sessions were held at each regularly scheduled Board meeting. Executive sessions are chaired by the Chairman and were chaired by the lead independent director prior to the Chairman's appointment in August 2020.

Board's Role in Risk Oversight

The Board plays an active role, both as a whole and at the committee level, in overseeing management of the Company's risks. Management is responsible for the Company's day-to-day risk-management activities. The Company relies on a comprehensive risk management process to aggregate, monitor, measure and manage risks. The risk management process is designed to enable the Board to establish a mutual understanding with management of the effectiveness of the Company's risk management practices and capabilities, to review the Company's risk exposure and to elevate certain key risks for discussion at the Board level. The full Board monitors risk through regular reports from each of the committee chairs and is apprised of particular risk management matters in connection with its general oversight and approval of corporate matters, as disclosed in the below chart:

We believe the division of risk management responsibilities described above provides an effective framework for evaluating and addressing the risks facing the Company, and that our Board leadership structure supports this approach because it allows our independent directors, through the independent committee chairs, to exercise effective oversight of the actions of management. The Safety, Risk and Sustainability Committee, as well as other members of the Board, receive updates from the Company's Chief Information Security Officer on the overall cybersecurity risk environment including the Company's enterprise-wide cybersecurity risk assessment results and key initiatives.

Risk Assessment of Compensation Policies and Practices

In fiscal year 2020, the Compensation Committee's independent consultant, Exequity LLP, conducted a risk assessment of the Company's compensation policies and practices as they apply to all employees, including

32

Table of Contents

executive officers. Exequity LLP reviewed the design features and performance metrics of our cash and stock-based incentive programs, along with the approval mechanisms associated with each, to determine whether any of these policies and practices could create risks that are reasonably likely to have a material adverse effect on the Company.

As part of the review, several factors were noted that reduce the likelihood of excessive risk-taking:

•
  Our compensation mix is balanced among fixed components such as salary and benefits, annual incentive payments and long-term incentives, including Performance Earning Program ("PEP") awards and restricted stock units granted under our 2020 Stock Incentive Plan, which typically vest or are earned over three years.
•
  The Compensation Committee has ultimate authority to determine, and reduce, if appropriate and consistent with applicable arrangements, compensation provided to our executive officers, including each of the NEOs.
•
  The Compensation Committee, under its charter, has the authority to retain any advisor it deems necessary to fulfill its obligations and has engaged Exequity LLP as its independent consultant. Exequity performs services for the Compensation Committee as described in the "COMPENSATION DISCUSSION AND ANALYSIS" section of this Proxy Statement.
•
  Our annual incentive programs for employees are funded in the aggregate based on the results of key financial metrics. Individual payouts are based on a combination of financial metrics as well as qualitative factors.
•
  Our long-term equity incentive awards, including PEP awards and restricted stock units granted under our stockholder approved 2020 Stock Incentive Plan, are all approved by either the Compensation Committee for our executive officers or by our Chief Executive Officer for non-executive officers.
•
  Our NEOs are subject to stock ownership guidelines, our insider trading policy and our clawback policy.

Based on this assessment, the Company concluded that its compensation policies and practices do not create risks that are reasonably likely to have a material adverse effect on the Company.

Committees of the Board of Directors

The Board has four standing committees: the Audit Committee, the Compensation Committee, the Nominating Committee and the Safety, Risk and Sustainability Committee. In accordance with NYSE regulations, each member of the Audit Committee, the Compensation Committee, and the Nominating Committee has been determined by our Board to be "independent." The committees operate under written charters that are available for viewing on the "Corporate Governance" area of the "Investors" section of our website at www.aecom.com.

The members of each of the standing committees are as follows:

Audit Committee

Audit Committee. The Audit Committee, which is composed solely of independent directors as defined under Rule 10A-3(b)(1) of the rules of the U.S. Securities and Exchange Commission and the regulations of the NYSE, appoints the Company's independent auditors, reviews the results and scope of the audit of our financial statements as well as other services provided by our independent auditors, reviews and approves audit fees and all non-audit services as well as reviews and evaluates our audit and control functions, including our internal audit function. Our Audit Committee held five meetings during fiscal year 2020. Our Board has determined that Mr. Schmitz, Chair of the Audit Committee qualifies as an "audit committee financial expert" as defined by the rules under the Exchange Act. The "R EPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS" is included in this Proxy Statement.

Compensation and Organization Committee. The Compensation Committee, which is composed solely of independent directors as defined under the regulations of the NYSE, non-employee directors, as defined under Rule 16b-3 of the Exchange Act, and outside directors for purposes of grandfathering provisions under Section 162(m) of the Code, oversees our compensation plans. Such oversight includes decisions regarding executive management salaries, incentive compensation and long-term compensation plans, as well as Company-wide equity plans for our employees. This committee also reviews the Board's compensation plan for non-employee directors and determines whether independent compensation consultants should be utilized. For further information regarding the Compensation Committee's processes and procedures for determining executive and non-employee director compensation, see the "COMPENSATION DISCUSSION AND ANALYSIS" section of this Proxy Statement. Our Compensation Committee held eight meetings during fiscal year 2020. The "REPORT OF THE COMPENSATION AND ORGANIZATION COMMITTEE OF THE BOARD OF DIRECTORS" is included in this Proxy Statement.

Nominating and Governance Committee. The Nominating Committee is composed solely of independent directors as defined under the regulations of the NYSE and is responsible for recruiting and retaining qualified persons to serve on our Board, including recommending such individuals to the Board for nomination for election as directors; for evaluating director independence; and for oversight of our compliance activities. The Nominating Committee also considers written suggestions from stockholders, including potential nominees for election, and oversees other governance programs such as the Company's Corporate Governance Guidelines. This committee also conducts performance evaluations for directors being elected at each annual meeting of stockholders, and engages in succession planning for the Board and key leadership roles on the Board and its committees. Our Nominating Committee held three meetings during fiscal year 2020.

Safety, Risk and Sustainability Committee. The Safety, Risk and Sustainability Committee oversees our corporate risk management, safety and sustainability programs and reviews the Company's overall policies regarding safety, cybersecurity, enterprise risk management, and environmental and social programs. Our Safety, Risk and Sustainability Committee held three meetings during fiscal year 2020.

Corporate Governance Guidelines

Our Board has adopted the Corporate Governance Guidelines, which set forth several important principles regarding our Board and its committees, including Board of Director membership criteria as well as other matters. Our Corporate Governance Guidelines are available for viewing on the "Corporate Governance" area of the "Investors" section of our website at www.aecom.com.

Codes of Conduct and Ethics

We have adopted a Code of Conduct that describes the professional, legal, ethical, financial and social responsibilities of all of our directors, officers and employees. We require all of our directors, officers and employees to read and acknowledge the Code of Conduct, and we provide regular compliance training to all our directors, officers and employees. Our directors, officers and employees are also encouraged to report suspected violations of the Code of Conduct through various means, including a toll-free hotline available 24 hour, 7 days a week in multiple languages, and they may do so anonymously. We do not tolerate acts of retaliation against anyone who makes an honest and sincere report of a possible violation of law or of our Code of Conduct or policies, or who participates in an investigation of possible wrongdoing. Many countries have enacted legislation to protect those who report misconduct, and we enforce any applicable protections afforded by such laws.

We also obtain year end affirmations from management personnel confirming compliance with the Code of Conduct. If we make substantive amendments to the Code of Conduct or grant any waiver, including any implicit waiver, to our principal executive, financial or accounting officer or persons performing similar functions or any director, we will disclose the nature of such amendment or waiver in a press release, on our website and/or in a report on Form 8-K in accordance with applicable rules and regulations. In addition, we have a separate Code of Ethics for Senior Financial Officers that imposes specific standards of conduct on employees with financial reporting responsibilities. We also have an Anticorruption Policy that provides specific guidance to help ensure that lawful and ethical business practices are followed while conducting international business activities. Our various policies are available for viewing on the "Ethics and Compliance" section of our website at www.aecom.com and in print to any stockholder that requests it. Any such request should be addressed to AECOM, 300 South Grand Avenue, 9th Floor, Los Angeles, California 90071, Attention: Corporate Secretary.

Communications with the Board of Directors

Our stockholders or other interested parties may communicate with our Board, a committee of our Board or one or more directors by sending a letter addressed to the Board, a committee of our Board or one or more directors to AECOM, 300 South Grand Avenue, 9th Floor, Los Angeles, California 90071, Attention: Corporate Secretary. All communications will be compiled by our Corporate Secretary and forwarded to the Board, the committee or the director, as appropriate.

Director Nominations, Board Refresh and Succession Planning

The Nominating Committee is charged with identifying, reviewing and recommending to the Board qualified individuals to become directors and regularly assessing the size and composition of the Board and recommending any changes to the Board. The Nominating Committee also engages in succession planning for the Board and key leadership roles on the Board and its committees.

The Nominating Committee reviews the appropriate skills and characteristics required of Board members in the context of the current composition of the Board, the operating requirements of the Company and the long-term interests of the Company's stockholders. In conducting this assessment, the Nominating Committee considers diversity, skills and such other factors as it deems appropriate to maintain a balance of knowledge, experience and capabilities. This periodic assessment enables the Board to update the skills and experience it seeks in the Board, as a whole and in individual directors, as the Company's needs evolve over time and to assess the effectiveness of efforts at pursuing diversity. From time to time, while identifying director candidates, the Nominating Committee may

35

Table of Contents

establish specific skills and experience that it believes the Company should seek to constitute a balanced and effective Board.

It is our belief that members of the Board should have the highest professional and personal ethics and values. We believe that the Board should be comprised of individuals who are committed to enhancing stockholder value with sufficient time to effectively carry out their duties. While all directors should possess business acumen, the Board endeavors to include an array of targeted skills and experience in its overall composition. Criteria that the Nominating Committee looks for in director candidates include business experience and skills, judgment, integrity, an understanding of such areas as finance, marketing, regulation, end markets and public policy and the absence of potential conflicts with the Company's interests. In particular, the Nominating Committee seeks candidates that have the following key skills and experience, each of which it is views as particularly important:

•
  senior leadership experience;
•
  industry experience;
•
  public company experience;
•
  financial expertise;
•
  government/regulatory expertise; and
•
  international expertise.

The Nominating Committee believes that it is essential that Board members represent diverse viewpoints and backgrounds. In identifying and selecting individuals, the Board and the Nominating Committee consider diversity, age, gender, skills, and such other factors as they deem appropriate to maintain a balance of knowledge, experience and capability. In addition, the Nominating Committee believes the Board should encompass individuals with diverse backgrounds and perspectives and representation of individuals from underrepresented communities. Diversity is an important consideration in the director nomination process because the Board believes that people of different genders, experiences, ages, races and ethnic backgrounds can contribute different, useful perspectives, while collaborating effectively to further the Company's objectives.

Our Nominating Committee will consider stockholder nominations for directors. The Nominating Committee evaluates any such nominees that are properly submitted using the same criteria it otherwise employs, as described in our Corporate Governance Guidelines. Any recommendation submitted by a stockholder must include the same information concerning the potential candidate as is required when a stockholder wishes to nominate a candidate directly. In addition, any such recommendation must be received in the same time frame as is required by our Bylaws when a stockholder wishes to nominate a candidate directly. To be timely, the notice must be received by the close of business no fewer than 90 and no more than 120 days prior to the date of the first anniversary of the preceding year's annual meeting of stockholders. However, in the event that the date of the annual meeting is advanced more than 30 days prior to such anniversary date or delayed more than 30 days after such anniversary date, or no annual meeting was held in the preceding year, notice by the stockholder to be timely must be received no more than 120 days prior to the date of the annual meeting and not less than the later of the close of business (a) 90 days prior to the date of the annual meeting and (b) on the 10th day following the day on which public announcement of the date of such meeting was first made by the Company.

To be in proper form, the notice must, as to each person whom the stockholder proposes to nominate for election or re-election as a director, set forth all information concerning such person as would be required in a proxy statement soliciting proxies for the election of directors in a contested election pursuant to Section 14 of the Exchange Act and

all written and signed representations and all completed and signed questionnaires required pursuant to our Bylaws. In addition, as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination is being made, the notice must also state the name and address, as they appear on the Company's books, of such stockholder and such beneficial owner and the class or series and number of shares of the Company that are owned of record and beneficially by such stockholder and such beneficial owner.

As to the stockholder giving the notice, or if the notice is on behalf of a beneficial owner on whose behalf the nomination is being made, as to such beneficial owner, and if such beneficial owner is an entity, as to each control person of such entity, the notice must state the class or series and number of shares of the Company that are owned of record and beneficially by such stockholder or beneficial owner and by any control person, a description of any agreement, arrangement or understanding with respect to the nomination between such stockholder or beneficial owner and any other person and by any control person, including, without limitation, any agreements that would be required to be disclosed pursuant to Item 5 or Item 6 of Schedule 13D (regardless of whether the requirement to file a Schedule 13D is applicable) of the Exchange Act, and a description of any agreement, arrangement or understanding (including, without limitation, any derivative or short positions, profit interests, options, hedging transactions, and borrowed or loaned shares) that has been entered into as of the date of the stockholder's notice by, or on behalf of, such stockholder, beneficial owner or control person, the effect or intent of which is to mitigate loss, manage risk or benefit from changes in the share price of any class or series of the Company's capital stock, or maintain, increase or decrease the voting power of the stockholder, beneficial owner or control person with respect to shares of stock of the Company. Stockholders who wish to nominate candidates for director must do so pursuant to these procedures.

Board Self-Assessment

The Nominating Committee facilitates an annual assessment of the performance of the Board and its committees and coordinates reports of the annual results to the full Board for discussions. The Nominating Committee also recommends changes to improve the Board and its committees. In 2020, the Nominating Committee engaged an outside law firm to obtain input from each director on the performance of the Board and its committees. In addition, each committee of the Board also conducted a self-evaluation discussion in executive session after the conclusion of fiscal year 2020.

Director Attendance at Annual Meetings

AECOM's policy is for directors to attend our annual meetings of stockholders unless there are extenuating circumstances. Eight members of our Board of Directors attended the 2020 Annual Meeting; such members attended remotely due to the Covid-19 pandemic.

Director Compensation

Information regarding the compensation of our non-employee directors is discussed below in "DIRECTORS' COMPENSATION FOR FISCAL YEAR 2020."

Director Retirement Policy

Our Corporate Governance Guidelines provide that unless otherwise recommended by the Nominating Committee and approved by the Board, directors are expected to retire from the Board at the end of the term of service during which they turn 75 years of age.

Related Party Transaction Policy

We have adopted a written related party transaction policy, which covers transactions in excess of $120,000 between the Company and our directors, executive officers, 5% or greater stockholders and parties related to the foregoing, such as immediate family members and entities they control. The policy requires that any such transaction be considered and approved by our Audit Committee, except that if the transaction is less than $1 million, the Chair of the Audit Committee may approve such transaction. In reviewing such transactions, the policy requires the Audit Committee, or the Chair, as appropriate, to consider all of the relevant facts and circumstances available to the Audit Committee, including (if applicable) but not limited to the benefits to the Company, the availability of other sources for comparable products or services, the terms of the transaction and the terms available to unrelated third parties or employees generally. The Board has also determined that certain transactions are pre-approved and do not require review by the Audit Committee. These include (i) compensation of the executive officers and Board members, which is reviewed by the Compensation Committee, (ii) a transaction with another entity in which the interested director or executive officer has an indirect interest in the transaction solely as a result of being a director or less than 10% beneficial owner of such other entity, and (iii) transactions with another corporation or charitable organization if the director's or executive officer's only interest is as a director or as a non-executive officer employee of the other corporation or organization and the amount involved does not exceed the greater of $1 million or 2% of the revenues of such other corporation or organization.

Under the policy, if we should discover related party transactions that have not been approved, the Audit Committee will be notified and will determine the appropriate action, including ratification, rescission or amendment of the transaction.

In fiscal year 2020, pursuant to the Starboard Agreement, we reimbursed Starboard $175,000 for certain fees and expenses (including legal expenses) incurred in connection with Starboard's involvement with AECOM through the date of the Starboard Agreement.

Stock Ownership Guidelines for Non-Employee Directors

Non-employee directors are subject to stock ownership guidelines, which are intended to align their interests with those of our stockholders. Under the guidelines, our non-employee directors must maintain ownership of AECOM stock at a multiple of five times the annual retainer by the end of the fiscal year following the fifth anniversary of the director's initial appointment to the Board. The minimum number of shares guideline is updated annually based on the current cash retainer ($100,000) and the 12-month trailing average AECOM stock price. Shares owned directly or indirectly, the value of vested but unexercised stock options and unvested restricted stock are counted toward the guidelines. The table below outlines the ownership of our non-employee directors as of September 30, 2020. All directors already meet or are expected to meet guidelines within the five (5) year transition period.

Executive Summary

Why approve our Say-on- Pay proposal? |  | ✓ Fiscal Year 2020 executive pay aligned with the strength of our financial performance and stock price outperformance ✓ Best in class shareholder outreach and responsiveness to feedback as evidenced by the decrease in CEO Annual Target Pay and enhancements to our incentive plan design and rigor of goals to address shareholder input

✓ Fiscal Year 2020 Financial and TSR Outperformance

​ |  | Highlights |  |
|  | AECOM exceeded its financial guidance on every key financial metric despite headwinds from COVID-19: • Adjusted EBITDA increased by 14%, which marked a new high for the Professional Services business and exceeded the high-end of our guidance • Segment Adjusted Operating Margin increased by 160 basis points to 12.3% and exceeded our guidance by 60 basis points; our margins have increased by 360 basis points since fiscal 2018 and lead the industry • Free Cash Flow of $619 million in the fourth quarter resulted in full year free cash flow of $341 million, which exceeded the high end of our guidance range • Completed Several Strategic and Financial Initiatives as part of our transformation into a higher-margin and lower-risk Professional Services business, including the divestitures of the Management Services business in January 2020, the Power Construction business in October 2020, and the Civil Construction business in January 2021 |  |
|  | • Transformed Balance Sheet enabled more than $600 million of stock repurchases between September 2020 and January 2021, while maintaining a gross leverage ratio below 3.0x, consistent with our objectives. • Achieved a TSR of 18.1% in Fiscal Year 2020, outperforming the S&P 500 and Russell 3000 indices in addition to our industry peers(1), due to the above achievements and strong execution through a period of great uncertainty. |  |  |  |

Stockholder Engagement and Executive Compensation Design Changes

Throughout the year, we have active and on-going dialogues with stockholders which are summarized as follows for Fiscal Year 2020:

What We Heard |  | What We Did and Why
Engage with stockholders |  | ✓ The Compensation Committee directors engaged with stockholders who collectively own greater than 50% of our total outstanding shares
​ | ​ | ​
CEO Quantum of Pay is high |  | ✓ The CEO total target pay is less than 50% of his predecessor's. The decision reflected a comprehensive review of the underlying business transformation, the peer group of companies to assess competitive market data, and the opportunity to recognize and reward future growth and success in the role.
​ | ​ | ​
Incentives should support long-term strategy |  | ✓ To support long-term profitable growth and the Company's capital allocation priorities, the Compensation Committee added Operating Cash Flow to the short-term incentive program in Fiscal Year 2021. ✓ To focus NEOs on growing earnings to drive shareholder value, the Compensation Committee added Adjusted Earnings per Share Growth to the long-term incentive program in Fiscal Year 2021 and elected to exclude the impact of share repurchases when calculating "per Share." Earnings per Share is preferable over Net Income as it has the added benefit of factoring how executive decisions can dilute shareholder interests. ✓ To further align our NEO's financial interests with that of our shareholders and reward for the TSR outperformance expected if NEOs execute the Company's financial plan and capital allocation policy, the Compensation Committee added relative TSR to the long-term incentive program in Fiscal Year 2021. ✓ Ultimately, short-term incentives focus on key metrics that hold management responsible for performance that drive shareholder value and for commitments made to investors. Long-term incentives focus on key metrics that align pay with shareholder value creation.
​ | ​ | ​
Goals should be rigorous |  | ✓ All financial goals materially align with the financial guidance we provide to our stockholders. ✓ Adjusted Earnings per Share Growth is based on underlying earnings growth from the business, excluding the impact of share repurchases. ✓ Relative TSR requires 55th percentile (above-median) performance for a target payout of 100%.
​ | ​ | ​
Vary short-term and long-term incentive metrics |  | ✓ The Compensation Committee removed Free Cash Flow from the long-term incentive program after adding Operating Cash Flow to the short-term incentive program to avoid redundant metrics. Cash Flow in the short-term better incentivizes managing our working capital while also supporting the continued execution of our capital allocation policy.

CEO Annual Target Pay |  | Other NEO Annual Target Pay

The primary elements of our executive pay program support our executive pay philosophy and are directly linked to individual and company performance as follows:

COMPENSATION GOVERNANCE, PROCESS AND DECISIONS

Executive Pay Philosophy

Our executive pay program is designed to support our strategy to deliver industry-leading profitable growth and stockholder value creation. It is underlined by our compensation philosophy that aims to attract and retain the best and brightest in our industry and recognize and reward outstanding achievements that drive long-term profitable growth and create stockholder value.

Pillars of our Executive Pay Program

Market Competitive: Assess NEO target pay levels against market compensation benchmarks prepared by our independent compensation consultant

Pay Supports Strategy: Incentive metrics designed to drive achievement of long-term financial and strategic objectives

Performance-Based: Impose performance conditions on the majority of our NEOs' compensation

Rigorous Goal Setting: Require performance that meets investor guidance and/or outperforms our industry for target payout on incentives

Shareholder Alignment: NEO financial interests aligned with those of our shareholders with long-term equity awards comprising a majority of each NEO's total compensation

Compensation Process

Compensation decisions are made as part of a year-long review and collaborative process with the following:

The Compensation Committee, which is composed solely of independent directors, has been authorized to determine and approve compensation for AECOM's executive officers. As part of the annual compensation planning process, the Compensation Committee reviews the NEOs' base salary, short-term and long-term incentive compensation, with a focus on the total reward package. As further described below, the Compensation Committee looks to a peer group of companies, as well as the broader market, as a baseline for compensation decisions for NEOs. However, AECOM does not target executive officer compensation at a specific level or percentage relative to compensation provided by the companies in the compensation peer group or broader market. Instead, when determining compensation for executive officers, the Compensation Committee takes into account a broad array of factors, including the experience level of the individuals in their current positions, the overall financial and strategic

46

Table of Contents

performance of the Company during the year and the performance and contribution of each executive during the year relative to individual, pre-defined goals and objectives. Differences in compensation levels for our NEOs are driven by the Compensation Committee's assessment, in its judgment, of each of our executive's responsibilities, experience and compensation levels for similar positions at peer companies. Except as otherwise noted in this CD&A, the Compensation Committee's determinations are subjective and the result of business judgment informed by members' experiences, analysis of peer company data, input from the independent consultant, and overall compensation trends.

Role of the Compensation Committee

–
  Reviews the Company's financial, strategic and operational metrics and goals, compensation peer group and approves the performance objectives of the CEO and other executive officers.
–
  Approves design changes to the executive compensation program, as applicable.
–
  Reviews full-year Company financial and strategic performance to understand what was accomplished relative to established objectives.
–
  Evaluates the CEO's performance in light of the review of Company performance.
–
  Discusses with the CEO his evaluation of the performance of each of the other executive officers relative to their individual performance objectives.
–
  Determines compensation amounts for the CEO and each of the other executive officers, taking into account:
  •
    Prior year's compensation;
  •
    Performance assessments;
  •
    Market considerations;
  •
    Individual performance and retention considerations;
  •
    Input from the Compensation Committee's independent compensation consultant; and
  •
    For the other NEOs, the CEO's recommendations.
–
  Reviews and approves the grants and payouts of long-term incentive equity awards.

With respect to the pool of long-term incentive equity awards, a number of factors are taken into account including but not limited to prior year grant size, growth in earnings and in employee headcount, the accounting expense, and the potential dilutive effects on stockholders. With respect to individual long-term incentive equity awards, the Compensation Committee considers individual performance, market data, including compensation for comparable positions at peer companies, and the strategic importance of the NEO's position to determine a dollar denominated long-term incentive equity value to be awarded to each NEO. The dollar value awarded by the Compensation Committee to each NEO is then converted into a specific number of units, based on the fair market value of AECOM common stock on the date of grant.

Compensation and Organization Committee's Independent Compensation Consultant

The Compensation Committee has the authority to retain the services of outside consultants to assist it in performing its responsibilities. The Compensation Committee engaged the services of the consulting firm Exequity LLP. During fiscal year 2020, the consultant provided data on the compensation and relative performance of compensation peer group companies as well as general industry data to the Compensation Committee, made presentations on regulatory and legislative matters affecting executive compensation, provided advice on the degree to which compensation arrangements are consistent with market practices, and consulted on other compensation matters as needed. Exequity LLP does not provide any services to the Company other than advising the Compensation Committee on compensation matters.

47

Table of Contents

The Compensation Committee has assessed the independence of Exequity LLP, considering the following six factors and other factors that it deemed relevant: (1) other services provided to the Company by Exequity LLP, (2) the amount of fees paid by the Company to Exequity LLP as a percentage of Exequity LLP's total revenue, (3) the policies or procedures maintained by Exequity LLP that are designed to prevent conflicts of interest, (4) any business or personal relationships between the individual employees of Exequity LLP involved in the engagement and a member of the Compensation Committee, (5) any AECOM stock owned by Exequity LLP's employees involved in the engagement and (6) any business or personal relationships between our executive officers and Exequity LLP or the employees of Exequity LLP involved in the engagement. Following such assessment, the Compensation Committee concluded that Exequity LLP is independent and that Exequity LLP's work raises no conflicts of interest.

Assessing Competitive Practice

As part of its due diligence when making compensation decisions, the Compensation Committee examines pay data for a group of comparable companies to stay current with market pay practices and trends and to understand the competitiveness of the Company's total compensation and its components of pay.

Compensation peer group data is supplemented with broader market survey data from Aon Hewitt and Willis Towers Watson. The Compensation Committee uses the compensation peer group and market survey data for informational purposes. The Company does not target a specific percentile or make significant pay decisions based on market data alone. The Compensation Committee considers Company performance as well as the level of responsibility, experience and tenure of the individual and performance in the role.

Fiscal Year 2020 Compensation Peer Group

The Compensation Committee, when developing the compensation peer group, identified the Company's competitors for talent and considered other various measures of size, scope and complexity, with a focus on revenue and enterprise value.

For Fiscal Year 2020, the Compensation Committee approved the following performance measures for our NEOs to support our strategy for attaining long-term profitable growth and stockholder value creation:

Corporate Leaders |  | Business Unit Presidents |  | Why Selected
Adjusted EBITDA |  | Pre-Variable Compensation ("Pre-VC") EBITA |  | Adjusted EBITDA focuses on underlying operational performance, is responsive to stockholder feedback to align compensation metrics with the metrics that investors use to evaluate performance. Pre-VC EBITA focuses on the "bottom-line" at the operating group level and thus provides a strong measure of the operational contribution to enterprise profitability.
​ | ​ | ​ | ​ | ​
NSR Operating Margin % |  | Operating Cash Flow |  | NSR Operating Margin focuses on underlying operational performance, including executing on restructuring and margin enhancing initiatives while focusing business development time and capital on the most profitable opportunities. Cash Flow incentivizes disciplined growth and risk management, operational efficiency and working capital management. It ensures working capital management is prioritized as a key contributor to long-term performance and ROIC, and strong operating cash flow supports the Company's capital allocation policy to return substantially all cash and cash flow to stockholders through share repurchases.
​ | ​ | ​ | ​ | ​
Key Performance Indicator ("KPI") Assessment |  | Encourages focus on the achievement of the Company's non-financial strategic objectives including sustainability and ESG

  Defined as AECOM Enterprise less the at-risk, self-perform construction businesses to be sold, which are reported in discontinued operations.
2
  Defined as Net Income attributable to AECOM before income tax expense (benefit), interest expense, interest income, depreciation and amortization expense, excluding acquisition and integration-related items, transaction-related expenses, financial impacts associated with expected and actual dispositions of non-core businesses and assets, and transformational restructuring related expenses.
3
  Defined as Adjusted Operating Income divided by Net Service Revenue. Adjusted Operating Income is defined as income from operations excluding acquisition and integration-related items, transaction-related expenses, financial impacts associated with expected and actual dispositions of non-core businesses and assets, amortization of intangible assets, and transformational restructuring related expenses. Net Service Revenue is defined as revenue less other direct costs.

Long-Term Incentives

Long-term incentive equity awards not only serve to retain our NEOs but also align our NEOs' interests with those of our stockholders by linking the final value to AECOM's stock price and, for PEP awards, being subject to performance metrics that drive our long-term strategy to build sustainable profitable growth and stockholder value.

Long-Term Incentive Award

As part of its review of Fiscal Year 2020 performance, the Compensation Committee analyzed the role and responsibilities of each NEO, including their past and current performance history, and prevailing market practices with respect to our compensation peer group and across industries. Based on these factors (as well as taking into consideration the Compensation Committee's collective experience regarding appropriate annual equity grant levels), the Compensation Committee approved the following equity awards in Fiscal Year 2020:

NEOs |  |  |  | 2019 |  |  |  | 2020 |  |  |  | % Change |  |
--- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | ---

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Gaurav Kapoor |  |  |  | $ | 475,000 |  |  |  | $ | 600,000 |  |  |  |  | 26.3 | % |
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Lara Poloni |  |  |  | $ | 700,000 |  |  |  | $ | 1,000,000 |  |  |  |  | 42.9 | % |
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

For fiscal year 2020, each NEO's long-term incentive equity award was comprised of the following:

Type |  |  |  | Weighting Percentage |  |  |  | Performance Measures and Vesting Requirements
--- | --- | --- | --- | --- | --- | --- | --- | ---
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
PEP |  |  |  | 60% |  |  |  | Metrics: – 50% to vest based on 3-year average ROIC achievements – 50% to vest based on 3-year cumulative attributable Free Cash Flow achievements
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
RSU |  |  |  | 40% |  |  |  | Continued service over 3-years (except in the case of certain qualifying terminations)
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

As to each PEP metric, because pre-established targets are competitively sensitive, they have not been disclosed; however, we note that the applicable targets aligned with guidance to shareholders.

Fiscal Year 2021 Long-Term Incentive Design Changes

In response to stockholder feedback and a continuous focus on aligning our incentives with our long-term strategy, the Compensation Committee adopted the following Fiscal Year 2021 performance metrics for our NEOs, each weighted equally:

2020 |  |  |  | 2021 |  |  |  | Rationale
--- | --- | --- | --- | --- | --- | --- | --- | ---
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Professional Services1 ROIC2 |  |  |  | Professional Services1 ROIC2 |  |  |  | – Critical to achieving long-term profitable growth
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Professional Services1 Attributable FCF |  |  |  |  |  |  |  | – Removing cash flow avoids duplicative metrics in short- and long-term incentives.
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
|  |  |  | Professional Services1 Adjusted EPS3 Growth |  |  |  | – Adding EPS aligns with how our stockholders will measure our performance in the long-term. Stockholders had commented that they will increasingly value the Company on an EPS basis following the sales of our Management Services and at-risk businesses. – Excluding share repurchases from EPS growth results focuses NEOs on delivering underlying business growth. – EPS is preferable over Net Income as it also considers how executive decisions can dilute shareholder interests.
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
|  |  |  | Relative TSR |  |  |  | – Rewards execution of the capital allocation policy which is expected to create shareholder value above and beyond achieving our long-term strategic objectives – Encourages outperformance with target TSR payout set above the median of peers at 55th percentile
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

1
  Defined as AECOM Enterprise less at-risk, self-perform construction businesses to be sold.
2
  Defined as the 3-Year Average Annual Adjusted NOPAT divided by the 3-Year Average Quarterly Invested Capital. Adjusted NOPAT is Adjusted Attributable Net Income plus Adjusted Interest Expense net of Interest Income (tax effected at a normalized 28.5% rate). Adjusted Attributable Net Income is defined as Net Income Available to Common Stockholders excluding foreign exchange gains/losses on forward contracts related to financing, acquisition and integration related expenses, transaction related expenses, transformational restructuring related expenses, financing charges in interest expense, the amortization of intangible assets, and financial impacts associated with expected and actual dispositions of non-core businesses and assets. Adjusted Interest Expense excludes financing charges in interest expense. Invested Capital is Attributable Shareholders Equity plus Total Debt less Cash and Cash Equivalents (all per balance sheet). Quarterly Invested Capital is defined as the beginning and ending balance of each respective quarter excluding (1) any balance with respect to all at-risk businesses to be sold and (2) changes to Accumulated Other Comprehensive Loss (i.e., held flat at Q4 FY2020 ending actuals).
3
  Adjusted EPS is calculated as (a) Adjusted Attributable Net Income (as defined in footnote 2) divided by (b) the Weighted Average Number of Common Shares Outstanding, on a diluted basis, for a fiscal year.

FY2021 RSU Grants for CEO and President

In conjunction with their promotions to CEO and President, respectively, Mr. Rudd and Ms. Poloni received the RSU portion of their annual Fiscal Year 2021 long-term incentive awards on August 15, 2020. These awards will fully vest on the third anniversary of the grant date and are included in the "Grants of Plan-Based Awards for Fiscal Year 2020" table. The PEP portions of their award were granted in December 2020, along with the FY2021 annual grants for all other NEOs and AECOM employees.

Performance Stock Option for CEO

In addition to the FY2021 RSU grant, Mr. Rudd received a $3,000,000 performance stock option award upon his promotion to CEO. The performance stock option is subject to both service and stock price vesting conditions, which must each be satisfied for the option to be vested as to the underlying shares. The service vesting requirement is satisfied in five (5) equal installments on each anniversary of the grant date, subject to continued employment. The performance vesting requirement is also satisfied in five (5) equal installments, upon our volume-weighted average price during a twenty-consecutive trading day period achieving each of the following AECOM stock price hurdles:

Target Stock Price |  |  |  | Percentage
​ | ​ | ​ | ​ | ​
Exercise Price plus 20% ($46.46) |  |  |  | 20%
​ | ​ | ​ | ​ | ​
Exercise Price plus 40% ($54.21) |  |  |  | 40%
​ | ​ | ​ | ​ | ​
Exercise Price plus 60% ($61.95) |  |  |  | 60%
​ | ​ | ​ | ​ | ​
Exercise Price plus 80% ($69.70) |  |  |  | 80%
​ | ​ | ​ | ​ | ​
Exercise Price plus 100% ($77.44) |  |  |  | 100%
​ | ​ | ​ | ​ | ​

In order to fully vest, AECOM's stock price needs to double compared to the grant date closing stock price (i.e., the Exercise Price), creating over $6.2 billion in market capitalization. Full vesting will also require outperforming our highest stock price from the last six (6) years by over 150% as both service and performance requirements must be met in order to become exercisable.

PERFORMANCE EARNINGS PROGRAM — 2020 ACHIEVEMENTS AND PAYOUTS

Fiscal Years 2017-2019 (PEP2017)

The number of units eligible to be earned was based on the Company's achievement of certain financial metrics, weighted 75%, and Relative TSR, weighted 25%. The financial metrics were measured over three (3) one-year performance periods with a 37.5% weighting for Adjusted EPS and a 37.5% weighting for Free Cash Flow Per Share. The Relative TSR metric was measured over a cumulative three-year performance period ending on December 14, 2019. PEP2017 earned 84.3% of target based on prior Fiscal Year 2017, 2018 and 2019 results and the below Relative TSR performance results.

December 15, 2016 – December 14, 2019 |  |  |  | Threshold |  |  |  | Target |  |  |  | Maximum |  |  |  | Actual |  |  |  | Payout (%)
--- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | ---
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Relative TSR |  |  |  | 25%' ile |  |  |  | 50%'ile |  |  |  | 75%'ile |  |  |  | 17.6%'ile |  |  |  | 0%
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

In Fiscal Year 2019, executive management made a strategic decision to restructure the Company to deliver long-term value to stockholders, which resulted in $95.4 million of transformational restructuring costs. As a result of the impact of the cost of restructuring, Fiscal Year Adjusted EPS earned 0% as the target levels were burdened by the cost of these investments. The final payout percentage above reflects this detriment taken by management for the benefit of the Company and its shareholders in the long-term.

Fiscal Years 2018-2020 (PEP2018)

PEP2018 has the same design as PEP2017. PEP2018 achieved 108.5% based on the Company's financial performance for Fiscal Years 2018 - 2020 and Relative TSR performance from December 15, 2017 to December 14, 2020. The table below details the final Fiscal Year 2020 financial performance and Relative TSR performance.

Year 3 (Fiscal Year 2020) |  |  |  | Threshold |  |  |  | Target |  |  |  | Maximum |  |  |  | Actual % |  |  |  | Payout (%) |
--- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | ---
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

December 15, 2017 – December 14, 2020 |  |  |  | Threshold |  |  |  | Target |  |  |  | Maximum |  |  |  | Actual |  |  |  | Payout (%)
--- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | ---
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

Similar to the results of PEP2017, for PEP2018, Adjusted EPS was negatively impacted by executive management's strategic decision to restructure the Company to deliver long term value to stockholders. The estimated payout percentage above reflects this detriment resulting from unplanned restructuring actions taken for the benefit of the Company and its shareholders in the long-term.

Fiscal Years 2019-2022 (PEP2019) and Fiscal Years 2020-2023 (PEP2020)

PEP2019 and PEP2020 have three-year performance periods to measure Return on Invested Capital and Free Cash Flow Per Share for PEP2019, and Attributable Free Cash Flow for PEP2020. Actual performance results will not be available until after the three-year performance period ends for both awards. Because pre-established targets are competitively sensitive, they have not been disclosed; however, we note that the applicable targets aligned with guidance to shareholders.

OTHER PROGRAMS, POLICIES AND GUIDELINES

Stock Ownership Guidelines for Named Executive Officers

NEOs are subject to stock ownership guidelines, which helps to ensure that their interests are aligned with those of stockholders. Under the guidelines, AECOM's CEO is required to maintain ownership of AECOM stock at six times base salary and the other NEOs at three times base salary. The minimum number of shares required to meet the guideline is updated annually based on each executive's salary and the 12-month trailing average AECOM stock price. Shares owned directly and indirectly, restricted stock units and vested stock options/shares are counted toward the guidelines. NEOs have five full fiscal years, starting from the date an executive is first subject to the guidelines, to comply.

In Fiscal Year 2020, the Compensation Committee increased the rigor of the stock ownership guidelines by removing unvested PEP units from shares counted toward meeting the applicable salary multiple requirements. As a result, our NEOs are required to hold a greater number of AECOM shares in the future to satisfy the requirements of our stock ownership guidelines.

The table below outlines the stock ownership of AECOM's NEOs as of October 2, 2020. Mr. Burke ceased serving as an officer on August 14, 2020. Messrs. Wotring and Morriss ceased serving as officers on October 2, 2020. Some of the continuing NEOs do not currently meet the stock ownership guidelines, however, each continuing NEO is expected to meet the guidelines by the end of his/her respective five-year transition period.

Benefit, Retirement and Perquisite Programs

To protect the Company's executives' health and well-being, facilitate the operation of the business, assist in the retention of current executives and aid in the recruitment of new executives, AECOM's NEOs are eligible to participate in benefit plans that are available to a substantial amount of all employees, including participation in retirement plans, medical insurance, dental insurance, life insurance and disability insurance programs. Further, the Company offers certain additional benefits only to executive officers and other senior officers, where applicable, which consist of the following:

•
  Executive Life Insurance. AECOM provides life insurance coverage with a benefit of up to $2 million for each NEO.
•
  Executive Disability Program. AECOM provides an Executive Disability Program, which offers salary replacement of up to 60% of salary in the event of an executive's disability (maximum $25,000 per month).
•
  Executive Health Program. Mr. Burke is the only remaining participant of this program that has been frozen to new participants. This plan provides up to 100% reimbursement for specified medical, prescription, dental and vision expenses.
•
  AECOM Executive Deferred Compensation Plan. A non-qualified deferred compensation plan that enables highly compensated U.S. employees to defer income tax on components of their compensation.

•
  Perquisites. The Company believes that offering certain limited perquisites, including an executive allowance to offset normal business expenses incurred by the executive in service to the Company, facilitates the operation of AECOM's business and assists in executive retention.

Employment Agreements, Severance Benefits and Change in Control Provisions

The Company has entered into a letter agreement with Mr. Burke dated March 6, 2014 and amended May 8, 2018 to add certain post-employment health insurance benefits; a letter agreement with Mr. Rudd dated June 20, 2020; and an employment agreement with Ms. Poloni dated October 19, 2020. Details of these agreements along with benefits provided to our NEOs under the AECOM Senior Leadership Severance Plan and AECOM Technology Corporation Change in Control Severance Policy for Key Executives can be found under the "PAYMENTS AND BENEFITS UPON TERMINATION OR CHANGE IN CONTROL" section of this Proxy Statement.

Clawback Provisions

The Compensation Committee maintains a clawback policy applicable to all current and former Section 16 officers that will apply if there is an accounting restatement due to material noncompliance with any financial reporting requirement under the securities laws. The Company is authorized to recover a portion of any short-term cash and long-term equity incentive awards paid to current or former executive officers during the three full fiscal years prior to the date of the covered event.

Hedging and Anti-Pledging

The Company's insider trading policy prohibits all directors, executive officers (as defined by Section 16 of the Exchange Act) and certain other employees designated as insiders from engaging in any hedging or monetization transactions, such as zero-cost collars and forward-sale contracts, involving Company securities.

In addition, the policy prohibits buying shares on margin and the pledging of Company securities by NEOs except in certain limited circumstances subject to Company approval and demonstration of the NEO's ability to repay the applicable loan without selling such securities.

Security Arrangement. The Company maintained a comprehensive security program for Mr. Burke that included ground and air executive protection deemed necessary to address the Company's security requirements. In selecting the level and form of protection, the arrangement considered the security risks faced by those in the Company's industry in general and security risks specific to the Company itself and its individuals. Pursuant to this Security Arrangement, the Board required that the CEO use private air travel for purposes of security, rapid availability and communications connectivity. This program was not designed to provide a personal benefit (other than the intended security).

  The target for the PEP2020 awards was 100% of the granted PEP units. The maximum for the PEP2020 awards was 200% of the granted PEP units.
(3)
  The grant date fair value amounts in this column are based on the following calculations:
  •
    All of the PEP awards subject to financial performance vesting conditions are calculated based upon the number of target PEP units granted multiplied by the closing common stock price of $43.06 on the grant date. These PEP awards will cliff vest 100% on December 16, 2022, following the close of the three-year vesting period, provided the performance conditions are achieved and subject to continued employment through the vesting date (except in the case of certain qualifying terminations).
  •
    The annual RSU awards granted on December 16, 2019 are calculated based upon the number of restricted stock units granted multiplied by the closing common stock price of $43.06 on the grant date. These annual restricted stock unit awards will cliff vest 100% on December 16, 2022, subject to continued employment through the vesting date (except in the case of certain qualifying terminations).
  •
    The RSU awards granted on August 15, 2020 to Mr. Rudd and Ms. Poloni in connection with their promotions are calculated based upon the number of RSUs granted multiplied by the closing common stock price of $38.72 immediately before the grant date, which fell on a weekend. These RSU awards will cliff vest 100% on August 15, 2023.
  •
    Options awards issued on August 15, 2020, are calculated based upon the number of options granted multiplied by the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 718 grant date fair value of $11.30, determined using a Monte Carlo valuation model. These special performance stock options will vest equal installments over a five-year vesting period subject to the achievement of certain stock price performance goals and satisfaction of applicable continued employment requirements.

  Except for Mr. Burke, the values in this column reflect amounts vested from the PEP2017 and RSU2017 awards granted on December 15, 2016. The value of the PEP2017 units is based on units earned at 84.3% of target for those with a relative TSR component (Mr. Rudd, Mr. Burke, Mr. Wotring, and Mr. Morriss) and 112.4% of target for those without the relative TSR component (Mr. Kapoor and Ms. Poloni) and the common stock price of $42.88 immediately before December 15, 2019, which fell on a weekend. The value of the RSU2017 units is also based on the common stock price of $42.88. For Mr. Burke only, the values in this column include amounts vested from the RSU2015 awards granted on November 19, 2014 in connection with his promotion to CEO, as well as from the annual equity RSU2018 and RSU2019 awards granted respectively on December 15, 2017 and December 17, 2018 that vested on March 17, 2020 as provided under Mr. Burke's severance agreement. The value of the RSU2015 units is based on the November 19, 2019 closing stock price of $42.59. The values of the RSU2018 and RSU2019 units are based on the March 17, 2020 closing stock price of $27.93.

Executive Nonqualified Deferred Compensation for Fiscal Year 2020

The following table sets forth information with respect to activity in the AECOM Executive Deferred Compensation Plan ("EDCP") during fiscal year ended September 30, 2020. The EDCP is a non-qualified plan that enables eligible employees to defer compensation in excess of amounts that may be contributed to the tax qualified RSP. Participants are allowed to defer the same elements of base salary into the EDCP as may be deferred under the RSP. The EDCP also permits deferral of sign on bonuses and annual incentive bonuses. Up to 50% of base salary and 100% of any eligible bonus may be deferred into the EDCP. The EDCP offers a fixed rate of return, which is determined each year.

Name |  | Executive Contributions in Last FY ($) |  | Registrant Contributions in Last FY ($) |  | Aggregate Earnings in Last FY ($)(1) |  | Aggregate Withdrawals/ Distributions ($) |  | Aggregate Balance at Last FY ($)(2)

W. Troy Rudd |  | $0 |  | $0 |  | $16,103 |  | $0 |  | $326,867

(1)
  Earnings were calculated using the rate of 5.00% and, to the extent exceeding 120% of the Applicable Federal Rate, were included in the Nonqualified Deferred Compensation Earnings column of the "SUMMARY COMPENSATION TABLE".
(2)
  $11,603 of this amount was reported as an executive contribution or earnings above the Applicable Federal Rate in the "SUMMARY COMPENSATION TABLE" in prior year proxy statements. The information in this footnote is provided to clarify the extent to which amounts payable as deferred compensation represent compensation reported in our prior proxy statements, rather than new deferrals of compensation.

Payments and Benefits Upon Termination or Change in Control

Payments and benefits that would be provided to each NEO in addition to those received by all employees (such as payout of 401(k) balances and paid time off) as a result of certain termination events are set forth in the table below. The amounts shown assume a qualifying termination of employment effective as of the last day of our fiscal year ended September 30, 2020.

Senior Leadership Severance Plan

In June 2020, the Compensation Committee approved the AECOM Senior Leadership Severance Plan (the "Severance Plan"). Each named executive officer currently employed by the Company is an eligible employee under the Severance Plan. The Severance Plan provides that, upon the termination of employment of an eligible employee by the Company other than for Cause (as defined in the Severance Plan) or due to death or disability (other than a termination in connection with a change in control of the Company), in addition to the payment of accrued obligations, the eligible employee will receive the following compensation and benefits: (i) a lump sum payment equal to one (1) times the eligible employee's base salary (except with respect to W. Troy Rudd, whose multiple is two (2) times base salary); (ii) a prorated target bonus for the fiscal year in which the termination occurred based on the number of days of service in the fiscal year; (iii) additional service vesting credit for purposes of outstanding equity awards based on the eligible employee's years of service with the Company (12 months of credit for five to ten years of service and 24 months of credit for more than ten years of service); and (iv) a lump sum payment in respect of the monthly employer portion of healthcare premiums multiplied by 12 (except with respect to Mr. Rudd, whose premiums are multiplied by 24). The receipt of the foregoing severance payments and benefits will be subject to the eligible employee's execution of a separation and release agreement that contains customary restrictive covenants, including obligations with respect to confidentiality and restrictions on soliciting the Company's employees and customers.

Change in Control Severance Policy for Key Executives

Pursuant to the AECOM Technology Corporation Change in Control Severance Policy for Key Executives (the "CIC Plan"), the NEOs in the table below will receive the following benefits in connection with a Change in Control (as defined in the CIC Plan):

•
  Upon a Change in Control only ("single trigger"): (i) full-vesting acceleration of equity awards only if the surviving entity does not continue or substitute such awards post-closing and (ii) deemed satisfaction of PEP Award targets based on actual performance through the change in control date and conversion of the earned PEPs to unvested restricted stock units that will continue to vest based on continued employment through the time-based vesting period for the PEPs (generally through December 15 following the end of the PEP performance cycle).

67

Table of Contents

•
  Upon a termination without Cause (as defined in the CIC Plan) or with Good Reason (as defined in the CIC Plan) within the period that begins 90 days prior to a Change in Control and ends 24 months following a Change in Control ("double trigger"): (i) full vesting acceleration of all unvested PEP (but based on actual performance through the change in control date), stock option, restricted stock units and other equity awards; (ii) a lump sum cash severance payment equal to a multiple (two times for our CEO and 1.5 times for other NEOs) of the NEO's base salary and average bonus earned over the three years prior to the year of termination (but including only those years in which the NEO was employed as a Key Executive of the Company); (iii) a pro-rata annual bonus payment, under the annual incentive compensation plan applicable to the executive, for the year in which the double trigger occurs, based upon the number of full months between the beginning of the applicable annual performance period and the executive's last date of employment, based upon the target level of performance and payable when bonuses are otherwise payable to the Company's executives; and (iv) continued health coverage for a number of years equal to the severance multiple (i.e., two years for our CEO and 1.5 years for other NEOs).

Michael S. Burke Letter Agreements

Pursuant to a letter agreement dated March 6, 2014 between the Company and Mr. Burke, in addition to Mr. Burke's participation in the Company's Change in Control Severance Policy for Key Executives, in the event that his employment had been terminated (i) by the Company for any reason other than "Cause" (as defined in the policy) or his death or disability or (ii) by Mr. Burke for "Good Reason" (as defined in the policy), and such termination did not occur within the "protection period" (as defined in the policy) then, the Company would have paid to Mr. Burke his accrued compensation through the termination date, a pro rata portion of the annual cash incentive award he would have received for the fiscal year in which employment terminated (based on the Company's actual performance over the entire year and Mr. Burke's number of full months of actual service during such fiscal year), a lump sum cash payment equal to two times the sum of his base salary plus the average annual cash incentive award he earned for the three fiscal years preceding the fiscal year in which such termination occurred, twenty four months of COBRA coverage premiums, and additional vesting of then outstanding equity awards as follows:

(a)
  any then-outstanding PEP awards would have remained outstanding and continued to be eligible to vest in accordance with their existing terms (as if he had remained employed and based on actual performance through the end of the applicable performance period);
(b)
  any then-outstanding unvested time based restricted stock units would have vested in full upon termination; and
(c)
  all other outstanding equity based compensation awards would have been treated as set forth in the applicable award agreements.

In addition, had Mr. Burke retired, notwithstanding anything to the contrary in an award agreement, Mr. Burke would have been entitled to full vesting of the then unvested portion of any outstanding award, as if he had remained employed through the end of each applicable vesting period (and based on actual performance). Any and all severance payments or benefits provided under the letter agreement would have been contingent upon the execution of a general release.

On May 8, 2018, the Company entered into an agreement to allow Mr. Burke and his eligible dependents to receive certain post-employment health insurance benefits (the "Amended Letter Agreement"). The Amended Letter Agreement, which updated the terms and conditions of Mr. Burke's post-employment insurance benefits as set forth in the 2014 letter agreement, provided that in the event Mr. Burke was terminated by AECOM for any reason other than Cause, or by Mr. Burke for Good Reason, Retirement or Total and Permanent Disablement (each a "Status Change"), then AECOM would extend health plan coverage and pay insurance premiums for a period of 24 months to Mr. Burke and his eligible dependents (the "Eligible Dependents"). Health plan coverage would have been provided at the expense of Mr. Burke and/or the Eligible Dependents commencing twenty five months after a Status Change. AECOM's obligation to provide health plan coverage to Mr. Burke and any of the Eligible Dependents would have ceased when Mr. Burke or any of the Eligible Dependents became eligible for comparable health insurance coverage at another employer or any of the Eligible Dependents becomes ineligible for coverage under the Company's health insurance plans.

On November 22, 2019, in connection with the previously announced CEO succession plan, the Company entered into a letter agreement that clarified that at the time a new CEO was appointed (or, if earlier, the day before the 2020

68

Table of Contents

Annual Meeting), Mr. Burke would cease serving as CEO and resign from all other positions at the Company. Mr. Burke ceased serving as CEO on August 14, 2020. At such time, in accordance with such letter agreement, Mr. Burke was entitled to the separation payments and benefits payable upon on a termination other than for Cause, consistent with the letter agreements entered into between the Company and Mr. Burke dated March 6, 2014 and May 8, 2018, although the pro rata bonus for the 2020 fiscal year was based on target bonus opportunity. The form of separation and release agreement that Mr. Burke was required to sign as a condition to receipt of the severance payments and benefits contains certain restrictive covenants, including a prohibition on Mr. Burke soliciting the Company's employees for one year following his date of separation.

Separation Agreement — Randall S. Wotring

On October 2, 2020, the Company and Randall A. Wotring mutually agreed that Mr. Wotring would resign from his position as Chief Operating Officer of the Company immediately, after which time he would serve in a non-executive officer capacity as Senior Advisor to the Chief Executive Officer until his retirement from the Company on December 31, 2020. Mr. Wotring and the Company entered into a separation and release agreement (the "Wotring Separation Agreement"), pursuant to which Mr. Wotring became entitled to receive the following compensation and benefits in accordance with the Company's Senior Leadership Severance Plan: (i) a lump sum payment equal to his annual base salary; (ii) a prorated annual incentive award payment for fiscal year 2021; (iii) a lump sum payment in respect of the monthly employer portion of healthcare premiums multiplied by 12; and (iv) 12 months of additional service vesting credit for purposes of his outstanding equity awards. The Wotring Separation Agreement also includes a general release of claims in favor of the Company as well as customary restrictive covenants, including obligations with respect to confidentiality and restrictions on soliciting the Company's employees and customers.

Separation Agreement — Stephen J. Morriss

On October 2, 2020, the Company and Stephen J. Morriss mutually agreed that Mr. Morriss would resign from his position as Group President, Design and Consulting Services—Americas of the Company effective immediately, after which time Mr. Morriss may continue to provide transition-related services to the Company under a short-term consulting arrangement on a month-to-month retainer at a pro rata monthly rate calculated based on his current base salary. Mr. Morriss and the Company entered into a separation and release agreement (the "Morriss Separation Agreement"), pursuant to which Mr. Morriss became entitled to receive the following compensation and benefits in accordance with the Company's Senior Leadership Severance Plan: (i) a lump sum payment equal to his annual base salary; (ii) an annual incentive award payment for fiscal year 2020; (iii) a lump sum payment in respect of the monthly employer portion of healthcare premiums multiplied by 12; and (iv) 12 months of additional service vesting credit for purposes of his outstanding equity awards. In addition, Mr. Morriss would receive $47,650 in relocation benefits. The Morriss Separation Agreement also includes a general release of claims in favor of the Company as well as customary restrictive covenants, including obligations with respect to confidentiality and restrictions on soliciting the Company's employees and customers.

Long-Term Incentive Equity Award Agreements

Pursuant to the terms of each of the restricted stock unit and PEP awards ("Long-Term Incentive Equity" in the tables below) held by our NEOs, upon the date of a termination of the executive's employment as a result of death or disability, all unvested restricted stock units and PEP awards will vest in full. Upon the date of a termination of the executive's employment as a result of Retirement, a pro rata vesting portion of then unvested restricted stock unit and PEP awards will vest. The proration will be calculated as a percentage where the denominator is the number of months in the performance cycle of the relevant award and the numerator is the number of whole months from the beginning date of the performance cycle through the date of the executive's termination.

CEO PAY RATIO

Pay Ratio

Pursuant to Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, below we provide disclosure of the ratio of our CEO's annual total compensation to that of our median compensated employee.

|  |  |  | Total Compensation |  |
--- | --- | --- | --- | --- | --- | ---
​ | ​ | ​ | ​ | ​ | ​ | ​
|  | CEO (combined total for Mr. Rudd and Mr. Burke) |  | $22,661,131 |  |
|  | Median Employee |  | $67,221 |  |
​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Ratio |  | 337.1 |  | ​
​ | ​ | ​ | ​ | ​ | ​ | ​

CEO Pay

The CEO pay ratio above for Fiscal Year 2020 is not representative of future years. The CEO pay reflects the combined total compensation paid to Mr. Rudd and Mr. Burke in Fiscal Year 2020 for their time served as CEO. For Mr. Burke, this reflects his total pay (including his severance and benefits payable upon his termination) as reported in the Summary Compensation Table. For Mr. Rudd, this reflects the portion of his base salary actually received on and after his promotion to CEO on August 15, 2020, a pro-rata of his Fiscal Year 2020 annual bonus, all of his equity awards granted upon his promotion, a pro-rata of his non-qualified deferred compensation earnings, and the portion of his All Other Compensation attributable to his time as CEO.

The CEO pay ratio below, however, is a better representation of future fiscal years as it reflects Mr. Rudd's total target pay package as CEO and excludes the severance and other benefits payable upon Mr. Burke's termination from the Company:

|  |  |  | Total Compensation |  |
--- | --- | --- | --- | --- | --- | ---
​ | ​ | ​ | ​ | ​ | ​ | ​
|  | CEO (Target Total Annual Pay) |  | $7,000,000 |  |
|  | Median Employee |  | $67,221 |  |
​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Ratio |  | 104.1 |  | ​
​ | ​ | ​ | ​ | ​ | ​ | ​

Global Employee Data Set

To derive our global employee data set, we employed the following methodology and assumptions:

•
  Data Source: We used our global human resource system of record to aggregate employee information from our various systems worldwide.
•
  Determination Date: We selected Monday, August 31, 2020, which falls within the last three months of our most recently completed fiscal year, as the determination date for identifying our median employee.

Consistently Applied Compensation Measure & Selection of Median Employee

To determine our median compensated employee, we used a Consistently Applied Compensation Measure (CACM). As our CACM, we used Annual Base Compensation, defined as base salary rate taking into account the employee's full-time or part-time status and the employee's scheduled hours of employment, plus any guaranteed 13th or 14th month period pay, as of the Determination Date. We exchanged non-U.S. compensation to US dollars applying the same fixed annual exchange rate used in our filed periodic reports.

The SEC's rules for identifying the median compensated employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

As part of the oversight process, the Audit Committee met five times during fiscal year 2020. Throughout the year, the Audit Committee met with the Company's independent registered public accounting firm, management and internal auditors, both together and separately in closed sessions, to review accounting, auditing, internal controls and financial reporting matters. In the course of fulfilling its responsibilities, the Audit Committee did, among other things, the following:

•
  reviewed and evaluated the performance and quality of Ernst & Young LLP, the Company's independent registered public accounting firm, and its lead audit partner in its determination to recommend the retention of Ernst & Young LLP, including by assessing the performance of Ernst & Young LLP from within the Audit Committee and from the perspective of senior management and the internal auditor;
•
  considered whether the provision of non-audit services by Ernst & Young LLP to the Company is compatible with maintaining the registered public accounting firm's independence;
•
  reviewed and discussed with management and Ernst & Young LLP the audited consolidated financial statements for the year ended September 30, 2020 and unaudited consolidated financial statements for the quarters ended December 31, 2019, March 31, 2020, and June 30, 2020;
•
  reviewed management's representations that the Company's consolidated financial statements were prepared in accordance with GAAP and present fairly the results of operations and financial position of the Company;
•
  discussed with Ernst & Young LLP the matters required to be discussed by PCAOB Auditing Standard No. 16, Communications with Audit Committees, as modified or supplemented and the overall scope and plans for the annual audit, the results of their examinations, their evaluation of the Company's internal controls and the overall quality of the Company's financial reporting;
•
  received the written disclosures and letter from Ernst & Young LLP required by the applicable requirements of the Public Company Accounting Oversight Board regarding Ernst & Young LLP's communication with the Audit Committee concerning independence, and discussed with Ernst & Young LLP its independence;
•
  monitored the reporting system implemented to provide an anonymous complaint reporting procedure;
•
  reviewed the scope of and overall plans for the annual audit and the internal audit program;
•
  reviewed new accounting standards applicable to the Company with the Company's Chief Financial Officer, internal audit department and Ernst & Young LLP;
•
  consulted with management and Ernst & Young LLP with respect to the Company's processes for risk assessment and risk mitigation;

•
  reviewed the Company's cybersecurity and data privacy risks and the Company's policies and controls designed to mitigate these risks; and
•
  reviewed the implementation and effectiveness of the Company's ethics and compliance program, including processes for monitoring compliance with the law, Company policies and the Code of Business Conduct and Ethics.

The Audit Committee also met with representatives of management, the internal auditors, legal counsel and the Ernst & Young LLP on a regular basis throughout the year to discuss the progress of management's testing and evaluation of the Company's system of internal control over financial reporting in response to the applicable requirements of the Sarbanes-Oxley Act of 2002 and related U.S. Securities and Exchange Commission regulations. At the conclusion of this process, the Audit Committee received from management its assessment and report on the effectiveness of the Company's internal controls over financial reporting. In addition, the Audit Committee received from Ernst & Young LLP its attestation report on the Company's internal control over financial reporting. These assessments and reports are as of September 30, 2020. The Audit Committee reviewed and discussed the results of management's assessment and Ernst & Young LLP's attestation.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors, and the Board has approved, that the audited consolidated financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2020, for filing with the U.S. Securities and Exchange Commission. The Audit Committee also approved the appointment of Ernst & Young LLP as the Company's independent registered public accountants for the fiscal year ending September 30, 2021, and recommended that the Board submit this appointment to the Company's stockholders for ratification at the 2021 Annual Meeting.

ANNEX A

Reconciliation of Non-GAAP Items

Our proxy contains financial information calculated other than in accordance with U.S. generally accepted accounting principles ("GAAP"). In particular, the Company believes that non-GAAP financial measures such as adjusted EBITDA, adjusted EPS and free cash flow provide a meaningful perspective on its business results as the Company utilizes this information to evaluate and manage the business. We use adjusted EBITDA and adjusted EPS to exclude the impact of non-operating items, such as certain amortization expense, certain depreciation expense, restructuring costs and non-core operating losses, to aid investors in better understanding our core performance results. We use free cash flow to represent the cash generated after capital expenditures to maintain our business. Our non-GAAP disclosure has limitations as an analytical tool, should not be viewed as a substitute for financial information determined in accordance with GAAP, and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP, nor is it necessarily comparable to non-GAAP performance measures that may be presented by other companies.
