2023 Annual Report   
Dear 
stockholders:

In fiscal 2023, we celebrated another 
monumental year. Across each of our 
strategic and financial objectives, we 
met or exceeded our target metrics. 
Our revenue growth continued to 
accelerate, our design backlog 
achieved record levels, our win rates 
are at or near all-time highs, and our 
position in the marketplace has never 
been stronger. 

We owe this success to our incredible teams who are committed to 
providing the best service to our clients and realizing our purpose 
of delivering a better world. As we continue to lead the industry, 
we recognize that our people are our most valuable asset. Their 
technical expertise, agility, and teamwork set us apart and drive 
our innovation. And more importantly, we continue to look after our 
colleagues with safety performance that leads our industry. 

By honoring our commitments and through effective 
collaboration, we are successfully expanding our long-term 
competitive advantage and positioning AECOM as the best place 
for our people in the industry. 

With our teams thinking and acting globally more than ever before, 
we achieved numerous milestones throughout the year, including:   

•  By concentrating our capital and technical expertise on our fastest-

growing markets worldwide, we have attained a high win rate on 
the most profitable opportunities. Our design business achieved 
record wins, and with a record backlog, we are poised for further 
growth. By generating strong and consistent cash flow, we are 
able to invest in our workforce continuously, while also investing to 
create shareholder value. 

•  Through the execution of our Think and Act Globally strategy, 
we brought the full power of our company to our pursuits and 
won positions on some of the world’s most complex programs. 
Notable wins during the year included the Brent Spence Bridge 
Corridor project in the U.S., the Pure Water Southern California 
program, multiple environmental contracts supporting the U.S. 
Navy, the Chemours green hydrogen facility expansion in France, 
transformative projects with NEOM in Saudi Arabia, the Tsing Yi–
Lantau Link in Hong Kong, and Western Harbour Tunnel in Australia. 
In each of these marquee projects, our expanded addressable 
market in program management and advisory is providing a critical 
advantage. 

•  We further invested in technical excellence and professional 
development through award-winning learning programs and 
enhanced Career Paths resources. We are committed to 
sustaining this momentum in the upcoming year, including 
through the launch of our latest Global Technical Academies 
courses. Our own best-in-class experts develop these courses 
and help ensure we continue to deliver the greatest possible 
outcomes for our clients around the world. 

•  In an increasingly digital world, we advanced digital delivery 

through automated and computational design, deploying new 
products like Program Management’s Program Advance and 
expanding our rapidly growing digital consulting business. Similarly, 
we enhanced global collaboration with our Enterprise Capabilities 
teams, expanding our capability to deliver more efficiently. We 
will continue to advance our digital strategy, aiming to create a 
truly differentiated client experience by leveraging products like 
PlanEngage™ and implementing our most advanced digital tools 
and methods through Enterprise Capabilities. 

•  We also took bold steps to embed sustainability and resilience 
into our work, establishing an industry-leading profile. Our ESG 
advisory practice grew at a double-digit pace, with wins including 
a sustainability component increasing nearly 300%. We solidified 
our position as the leader in helping our clients to decarbonize, 
transition to renewable and sustainable energy sources, enhance 
water security, and invest in nature and biodiversity. Furthermore,

AECOMI am incredibly proud of 
where our organization stands 
today. Our consistently strong 
performance is expanding our 
competitive advantage and the 
long-term earnings power of the 
business to deliver growth into 
the future.

—Troy Rudd

I’m proud of the positive societal impact we made for the 
communities we serve. Internally, we achieved our near-term 20% 
gender diversity target for our leadership team and continued to 
progress against our regional diversity targets while fostering an 
environment where all voices are respected and valued. 

•  Reflecting our focus on value creation, we allocated approximately 

$475 million of capital to shareholders through our quarterly 
dividend and share repurchase programs. In addition, we increased 
our quarterly dividend by 22% in November, marking the second 
year of annual dividend increases of more than 20%, and increased 
our share repurchase authorization to $1 billion. Our commitment 
to value creation was further reflected in our long-term financial 
growth outlook we unveiled in December, which includes an 
expectation for strong organic NSR growth, further margin 
expansion, double-digit per share earnings growth, and continued 
strong free cash flow.

As we look ahead, the strength of our company’s foundation is 
unparalleled—and with demand at unprecedented levels, the 
opportunities in our markets remain equally strong. With the best 
technical consultants in the industry, an aligned culture focused 
on global collaboration, and our investments in the highest-
returning markets, I remain confident the best days for AECOM 
are ahead of us. 

We appreciate your continued support and look forward to another 
successful year.

2023 Annual ReportFY23 financial  
performance

Our strong fiscal 2023 performance met or exceeded our guidance on every key 
financial metric. Reflecting our culture of collaboration and focus on winning what 
matters, our full-year win rate set a new record and contracted backlog in the design 
business increased by 15%1 to an all-time high. 

In addition, we extended our track record of outperformance with record profitability, 
continued industry-leading margin expansion, and strong cash flow. These successes 
reflect the benefits of continued execution of our strategy, high-returning organic 
growth, and our technical advantage. 

By expanding our addressable market in program management and advisory, we aim 
to support clients with their most critical projects and programs. Simultaneously, 
by developing our digital delivery capabilities, we enhance our ability to meet their 
evolving needs. In this strong position, we are ideally suited to capitalize on global 
investments in infrastructure, sustainability, resilience, and the energy transition, which 
are expected to drive strong demand in 2024 and beyond.

From a progressive career development philosophy that offers multiple paths to Global Technical

for learners at every career level, our people are supported with resources to build connections 
throughout our organization and explore the opportunities that inspire them. 

To help navigate the tremendous opportunities at AECOM, we encourage everyone to develop 
their core skill set and capabilities and then explore different roles across our business to 
broaden their experience.

“

 One benefit about a large organization like AECOM is 
the opportunities to chart your own career path. You 
can quite literally transform your career over and 
over again without ever leaving AECOM. Whether 
you stay focused on a single career trajectory or move 
between multiple paths, there is no limit to what you 
can achieve if you are motivated and open to new 
opportunities.

“

 The sky is the limit at AECOM. You 
should have the ambition to rise to the 
top of the organization. You should 
be open to opportunities to move to 
different roles in the organization—to 
a new location, a different business 
line, a new type of service, a different 
career path.

2023 Annual ReportCreating a culture of flexibility,  
trust, performance, and well-being

Freedom to Grow is our work-life balance framework designed 
to support the balance and flexibility our people need to thrive 
and deliver their best for their team and clients. Employees and 
managers work together to evaluate work schedules and locations 
to align on a flexible work arrangement that prioritizes work 
responsibilities while supporting individual needs and includes at 
least three days a week, or 60% of their schedule, working from an 
AECOM office or client site.

Eligible employees in the U.S. and Canada also enjoy our Flexible 
Time Off policy, which eliminates vacation accrual limitations, 
ensuring our people can take time off to support their needs and 
well-being and be their best when at work.

Flexibility at AECOM goes far beyond just when and where we work. 
We consider our holistic experience, respecting diversity in work, 
communication and thinking styles, and what makes each of our 
employees unique. 

Work time 

Break the 9-5

This includes our culture of well-being, which helps safeguard our 
people, clients, and communities. By being well, we bring our best 
selves to everything we do personally and professionally. We are 
focused on six pillars of well-being: emotional, financial, intellectual, 
physical, social, and for the planet. 

This year, in support of emotional well-being, we introduced a new 
global Mental Health Allies network—dedicated AECOM colleagues 
who are equipped with the language, tools, and knowledge to speak 
one-on-one with those who are facing a mental health challenge 
and connect them to resources that can help. Global Mental Health 
Allies are specially trained by a Certified Mental Health First Aid 
instructor to understand the signs and symptoms of mental health 
challenges and be well-versed in how to listen nonjudgmentally and 
respect privacy.

AECOMFostering a welcoming and 
respectful environment

AECOM is committed to creating a respectful, inclusive 
culture that celebrates diversity—allowing us to bring our 
best ideas to our clients, which is what ultimately contributes 
to a strong organization and better outcomes for the 
communities we serve.

Enterprisewide awards received by AECOM led by assessments 
and submissions in the Americas region include: the top score on 
the Human Rights Campaign Foundation’s assessment of LGBTQ+ 
workplace equality for the sixth consecutive year, the 2024 
Military Friendly Employer Friend award by Viqtory, and the 2024 
Diamond Award for Diversity, Equity, Inclusion, and Belonging by the 
American Council of Engineering Companies of Pennsylvania. 

In Europe and India, we received our Silver level diversity and 
inclusion accreditation with The Clear Company, after our first 
Bronze designation received just last year. The Clear Company is a 
recognized Inclusion Standard that provides clarity and direction 
to continually improve our inclusive and fair work practices. At 
the Employers Network for Equality & Inclusion (enei) Inclusivity 
Excellence Awards, AECOM won the Inclusive Culture Award and 
Influencer of the Year. The awards showcase organizations and their 
achievements in promoting and progressing workplace diversity, 
equality, inclusion, and belonging. 

Accolades received in Asia include the Inclusive Enterprise Gold 
Award from the Dream Come True Foundation in Hong Kong, in 
recognition of companies employing young people with special 
educational needs and providing them with meaningful career 
prospects. AECOM Hong Kong is also a key partner in the Inclusive 
100 initiative launched by the Dialogue in the Dark (HK) Foundation, 
which aims to promote inclusive workplaces that value people with 
varying abilities.

In Australia and New Zealand, we 
attained Bronze Tier Status from the 
Australian Workplace Equality Index 
(AWEI), a national benchmark on 
LGBTQ+ workplace inclusion. AWEI comprises the largest and only 
national employee survey designed to gauge the overall impact of 
inclusion initiatives on organizational culture as well as identifying 
and nonidentifying employees. The Index drives best practices 
in Australia and sets a comparative benchmark for Australian 
employers across all sectors.  

We are advancing 
efforts globally in 
four key areas:

Building diverse talent

Ensuring, through our recruitment 
efforts, that our teams reflect the 
diversity of the communities we serve 
with a focus on  building leadership 
accountability, and partnering 
with nonprofit organizations and 
universities to build the talent pipeline 
for the future.

Expanding understanding

Expanding understanding and 
empathy among employees through 
employee resource groups, ED&I 
events and celebrations, unconscious 
bias training, and family-friendly 
benefit policies.

Thinking without limits

Thinking without limits by prioritizing 
social equity and impact in every 
project we pursue and in every 
innovative solution we deliver.

Enriching communities

Enriching communities through pro 
bono work, volunteerism, philanthropy,

Cultivating community and connection

Our Pride ERG does incredible work to develop tools and resources 
to educate and ensure the visibility of LGBTQ+ groups and 
allies. This year for Pride Month in June, our Pride ERG chapters 
collaborated to create a one-of-a-kind, unifying event that truly 
represented how we Think and Act Globally. 24 hours of Pride 
was a global event that consisted of informative and interactive 
programming spanning across the Americas, Asia, Europe and India, 
and Australia and New Zealand. The wide-ranging list of events 
included everything from trivia and DJ sets to insightful panels 
with LGBTQ+ colleagues and speakers to sessions for parents of 
LGBTQ+ children. It was an opportunity for our employees to share 
stories, resources, and demonstrate allyship.

We continue to encourage and support bonding and community 
within AECOM. Employee resource groups (ERGs) help strengthen 
the connections between us and the communities we serve. They 
provide rich opportunities for the exchange of ideas and powerful 
dialogue, professional networking and development, talent 
attraction, and philanthropic impact. 

In 2023, we launched two new global ERGs: Beyond Abilities, a 
community for the disabled, neurodiverse, and caregivers in the 
Americas, Europe, and India that aims to foster a collaborative and 
inclusive environment to support people of all abilities, so they 
are empowered to succeed at AECOM; and Connect, a community 
for our early career professionals spanning the Americas, Europe 
and India, and Australia and New Zealand that strives to cultivate 
an environment where insights from all levels of expertise can be 
considered. Our ERGs lead many cultural activities to help raise 
awareness and understanding of what makes us unique and provide 
an important platform and connection for our people.

AECOMCelebrating, attracting, and 
retaining women in our industry

One of our key commitments to improve social outcomes across our 
work is to ensure our teams reflect the diversity of the clients and 
communities we serve. We continue to make progress on gender 
diversity targets, including the achievement of our 20% target for 
women in leadership roles, while continuing to progress against our 
35% target for our overall workforce.  

To celebrate the women in our industry, we take part in International 
Women’s Day in March and International Day of Women in 
Engineering in June on a global scale. Our women colleagues are 
recognized throughout the year, but we set these moments apart by 
showcasing the incredible contributions made by our colleagues and 
the career possibilities that are available here.

Furthered our 
commitment to 
biodiversity and 
nature 

We recognize that our focus 
on the environment cannot 
just be limited to carbon 
emissions—we must be 
evaluating the impact of our 
operations and our client 
work on biodiversity and 
nature more holistically. That 
is why during fiscal 2023 we 
formalized a biodiversity 
statement that has been 
signed by our CEO, Troy Rudd, 
and includes commitments 
to support the Global 
Biodiversity Framework of 
reversing nature loss by 2030. 
Furthermore, reflecting our 
commitment to sustainability 
and leadership in advancing 
environmental stewardship 
industrywide, we were 
awarded the Terra Carta Seal 
by the Sustainable Markets 
Initiative in fiscal 2023.

28

Continued to grow our 
ESG Advisory practice 
through technical 
excellence, including 
our ScopeX™ process

As we continue to enhance the 
sustainability of our operations, 
we also continue to grow our ESG 
Advisory practice to further embed 
sustainability and resilience into our 
client offering. With unprecedented 
demand, we increasingly are 
integrating sustainability services in 
our projects, with revenue generated 
from projects with an ESG-embedded 
service up by more than four times 
in fiscal 2023. Our leading technical 
expertise, combined with our ambitious 
approach to sustainability, is creating 
a unique client value proposition that 
is also contributing to record win rates

One example of embedding 
sustainability principles into 
everything we do is our ScopeX™ 
approach, which considers materials, 
site locations, logistics, and 
construction methods to reduce and 
eliminate a project’s impact on the 
natural environment. We minimize 
energy use, optimize sources 
of renewable power, and, where 
feasible, work with and enhance 
natural habitats to eliminate carbon 
emissions. We believe that ScopeX™ 
will be our biggest contribution to help 
end the climate emergency.

By decarbonizing the built 
environment and supporting our 
clients to achieve their net-zero 
agendas, we’re striving to improve the 
cities and communities we serve and 
deliver a better world.

Advanced our social 
value initiatives

We believe that investing in local 
communities to create positive 
social and economic outcomes is 
at the heart of generating social 
value. We work with our clients, 
partners, and suppliers to link 
the opportunities presented 
by our projects to the needs 
of the local communities we 
operate in, driving the creation of 
positive, lasting legacies. Social 
value is critical to achieving our 
Sustainable Legacies strategy 
and making sure that no one is 
left behind. 

In fiscal 2023, we continued to 
advance our equity, diversity, 
and inclusion initiatives in our 
company with the achievement 
of our near-term target of 
20% women in leadership. 
We also continue to make 
further progress against 
our 35% near-term target of 
women companywide while 
also advancing our nongender 
diversity targets within each 
region of our business.

Promoted 
positive 
impact in our 
communities

Our corporate responsibility 
platform is focused on delivering 
access to safe and secure 
infrastructure to those who need 
it most via strategic nonprofit 
partnerships, pro bono work, 
skills-based volunteering, and 
philanthropy. In fiscal 2023, we 
continued to take a leading role in 
the response to extreme events 
that devastated communities. 
This was no more apparent than in 
the aftermath of the Maui, Hawaii 
fires, where we contributed 
nearly $300,000 through an 
employee-matched donation 
campaign in collaboration 
with the American Red Cross’s 
Hawaii Wildfires Relief Fund. 
Funds raised contributed to 
ongoing assessment activities, 
distribution of relief supplies, and 
other important work.  

Our technical teams partner with 
nonprofit organizations in their 
local communities to provide 
critical design, engineering, and 
infrastructure solutions, and we 
maintain our relationship with our 
enterprise strategic nonprofit 
partners—Engineers Without 
Borders and Water for People. In 
FY’23, our employees donated 
more than $80,000 to Water for 
People. 

AECOMReducing emissions towards our Science Based  
Targets initiative-validated net zero targets 

To keep up with the latest best practices and climate science, we set a more ambitious 2040 
net zero target that was validated by the Science Based Targets initiative (SBTi) in 2022, making 
AECOM one of the first companies globally to achieve this at the time. As part of our updated, more 
ambitious net zero commitment, we are also targeting:

60%

50%

Reducing Scope 1 and 2 emissions 
60% by 2030  
(compared with 2018)

Reducing Scope 3 emissions 
50% by 2030  
(compared with 2018)

90%

Reducing all emissions 
90% by 2040  
(compared with 2018) 

Our global Scope 1 and 2 emissions, 
covering fleet vehicles and office energy, 
respectively, declined by 61% from our fiscal 
2018 baseline year as a result of key travel 
and real estate initiatives. We continue to 
make progress against this commitment 
in various ways, including by increasing 
the efficiency of our office spaces, further 
extending sustainability guidelines for future 
office refurbishments and relocations, and 
transitioning our automotive fleet to either 
more fuel efficient or electric vehicles. 

Reducing our Scope 3 emissions means 
focusing on our supply chain emissions 
and business travel. Our supply chain 
emissions have declined by 23%, including 
a 65% reduction in business travel since 
2018. We are looking to build on this 
progress through initiatives such as our 
expanded supplier engagement program, 
through which we are reaching out to the 
top 80% of our suppliers by emissions to 
support them in setting targets and their 
own decarbonization efforts.

Reducing all emissions 90% by 2040 
(compared with 2018) and offsetting 
remaining emissions in 2040 through high-
quality carbon removal projects—achieving 
this long-term reduction target will mean 
building on the initiatives across Scopes 1, 2, 
and 3 as put in place for our 2030 targets. 

We also maintained our operational net zero status in 2023 and commit to maintaining operational 
net zero status annually. We achieved operational net zero through reduction of Scopes 1 and 2 
emissions in line with climate science and offsetting remaining emissions.

2023 Annual ReportLeading by example:  
Advising on the energy transition

With our own industry-leading sustainability journey to guide us, 
we're helping organizations protect the environment, enhance 
communities, integrate sustainable development into everyday 
business, and improve governance. 

These ambitions look different for every organization and 
industry, so we help clients understand where they are in 
the energy transition continuum and then develop a tailored 
roadmap with tangible next steps so they can build momentum 
to achieve their goals.

We're advancing our leading advisory position by partnering 
with clients to navigate and accelerate their energy 
transition. Our flagship global thought leadership report, The 
Future of Infrastructure, Lost in Transition? is driving these 
conversations. Based on qualitative and quantitative research 
carried out with nearly 850 senior executives spanning nine 
industries and 22 countries, it provides our clients and the 
broader industry with practical, profitable, predictable, and 
people-centric strategies to achieve net zero. 

Powering New York with offshore wind 

In line with our client, Equinor’s commitment to cleaner energy 
for New York, the Beacon Wind project was carefully crafted 
with a strategic approach. Our role centers on environmental 
permitting and engineering for the offshore lease area, covering 
128,000 acres south of Nantucket, MA. This area is integral to 
Equinor’s portfolio, including Empire Wind 1, Empire Wind 2, and 
Beacon Wind 1, collectively aiming to provide 3.3 gigawatts of 
electricity to New York.

Community engagement is vital, involving Indigenous nations, 
stakeholders, and local fishing communities to assess and 
minimize the project’s impact on the local economy. Working 
closely with the Bureau of Ocean Energy Management (BOEM) 
and the National Oceanic and Atmospheric Administration 
(NOAA), we are obtaining approvals for the site assessment plan 
(SAP) and conducting essential surveys and studies. 

COP28 

As the sustainability consultant for the 28th UNFCC Conference 
of Parties (COP28) in the United Arab Emirates (UAE), we played a 
pivotal role in shaping a leading sustainability and environmental 
management strategy, guiding the event toward carbon 
neutrality. Our comprehensive approach established frameworks, 
management guidelines, and carbon management plans, 
integrating sustainability processes and carbon-tracking tools 
into the event. Our role extended beyond COP28 itself, creating 
the foundation for sustainable operations in future COPs and 
elevating sustainability standards within the UAE’s event sector. 

Leveraging our UAE-based environmental consultants and global 
network of experts, we provided advisory services to attain ISO 
20121 certification for sustainable events and supported the 
implementation of operational sustainability throughout the 
event’s supply chain. Following the event, there’s a tremendous 
amount of work to do to move us from ambition to action. 
Initiatives like the near-zero emissions building breakthrough 
highlight the value of COP28, but also that we must now take 
steps to operationalize.

2023 Annual Report   
 
   
 
AECOM’s Safety for Life program, driven by 
leadership commitment and empowered 
employees, has been fundamental to 
delivering industry-leading performance 
and recognition by clients and agencies 
around the world. A key example of this was 
AECOM’s Royal Society for the Prevention 
of Accidents (RoSPA) President’s Award 
for having achieved 14 consecutive annual 
Gold Awards. Our culture’s impact was also 
recognized by the United States Occupational 
Safety and Health Administration (OSHA), with 
our AECOM Turner NBA Joint Venture Intuit 
Dome project awarded Voluntary Protection 
Programs (VPP) Star status.

The previous year highlighted programs 
to support exercising both collective 
and individual care, including our “Take a 
Moment” focus, driven globally through 
first-person video accounts shared by our 
people. “Take a Moment” emphasizes the 
critical importance of exercising mindfulness 
before acting and pre-planning to produce 
safe work environments, while continuing 
to empower employees to “Stop Work” in 

unsafe conditions. The power of our Culture 
of Caring was also highlighted with AECOM’s 
celebration of International Women in 
Engineering Day. Our women engineers 
published testimonials sharing how they make 
safety seen as they execute AECOM’s Safety 
for Life program in their work. 

Over the course of fiscal 2023 our Global 
Safety, Health and Environment (SH&E) 
teams also collaborated to improve the 
accessibility of employee resources and 
tools. One example is the execution of a new 
innovative Global SH&E Lessons Learned 
repository. This digital tool provides easy 
access and searchability of lessons learned 
from all regions and business lines, extending 
the reach of incident prevention efforts. 
These represent only a few examples of the 
efforts that contribute to our continuous

and insight, and the strength of evolving 

security technologies and processes, 
AECOM’s Global Security and Resilience 
(GSR) team provides our global operations 
with the professional knowledge and 
awareness needed to eliminate or minimize 
threats to our personnel and operations.

The GSR team expertise has proactively 
supported proper project planning to 
effectively manage applicable security risks 
and, thereafter supports execution across 
our operations. From advising on situational 
awareness on-site, in the office or while, 
to—in more extreme cases—helping our 
people when they find themselves stranded 
in locations due to extreme weather or 
other dangerous geopolitical events, our 
GSR team has been critical to our business 
continuity. While continuing to support 
operations in high- and elevated-risk 
countries, our team also actively identifies 
and manages security risks with high 
potential in low-risk countries. Maintaining 
the security of our personnel and our 
operations is crucial and a critical element 
of our core value, Safeguard.

AECOMData security   

We understand the evolving landscape of cybersecurity threats, and 
we constantly invest in measures to safeguard data from unauthorized 
access, cyberattacks, phishing, and other malicious activities.

We prioritize data security through a comprehensive Information 
Security Program aligned with industry standards like ISO 27001, 
NIST CSF, and NIST 800-53. This program safeguards our information 
against unauthorized access, alteration, disclosure, or destruction.

Ethics and compliance

We believe good ethics is good business. We are committed to always 
prioritizing ethics and integrity, not simply because it’s the right 
thing to do, but also because it helps safeguard our people and our 
company from potential wrongdoing while strengthening our brand 
and reputation around the world.  

Our Code of Conduct outlines the legal guidelines we must follow and 
general ethical principles to help each of us make the right decisions 
when conducting business worldwide. Leaders at the company 
promote ethical behavior through a global ethics committee as well 
as through regional ethics committees. Our employees take part 
in annual Code of Conduct training, which received 100 percent 

completion in fiscal 2023. We also provide supplemental training on 
ethics and compliance issues throughout the year and incorporate 
ethics and compliance principles in our training for new employees 
and new managers. 

Furthermore, we have a comprehensive cross-functional ethics and 
compliance program focused on preventing issues from occurring, 
detecting them if they happen, effectively and expediently resolving 
issues, and capturing and communicating lessons learned to prevent 
them from repeating. As a result, we have been recognized seven 
times by Ethisphere as one of the World’s Most Ethical Companies. 

Human rights commitment

AECOM is a signatory to the U.N. Global Compact and adheres to the International Bill of Rights and International Labor Organization’s 
Declaration of Fundamental Principles and Rights at Work, which underscore our commitment to abiding by and promoting international 
human rights. AECOM’s Human Rights Statement and Modern Slavery Act Statement provide more detail on our policies and commitments 
related to ensuring fundamental rights at work, such as reasonable working conditions and wages, the right to collective bargaining, and 
combatting human rights abuses, such as modern slavery and child labor.

ITEM 1. BUSINESS 

PART I 

In this report, we use the terms “the Company,” “we,” “us” and “our” to refer to AECOM and its consolidated subsidiaries. 
Unless otherwise noted, references to years are for fiscal years. Our fiscal year consists of 52 or 53 weeks, ending on the Friday closest 
to September 30. For clarity of presentation, we present all periods as if the year ended on September 30. We refer to the fiscal year 
ended September 30, 2022 as “fiscal 2022” and the fiscal year ended September 30, 2023 as “fiscal 2023.” 

Overview 

We  are  a  leading  global  provider  of  professional  infrastructure  consulting  services  for  governments,  businesses  and 
organizations throughout the world. We provide advisory, planning, consulting, architectural and engineering design, construction and 
program management services, and investment and development services to public- and private-sector clients worldwide in major end 
markets such as transportation, facilities, water, environmental, and new energy. 

According to Engineering News-Record’s (ENR’s) 2023 Design Survey, we are the second largest general architectural and 
engineering design firm in the world, ranked by 2022 design revenue, and we are the number one ranked transportation design, facilities 
design, environmental engineering, environmental consulting and environmental science firm in the world. In addition, we are ranked 
by ENR as the leading firm in a number of design end markets, including several water infrastructure-related markets, as well as the 
number two green design firm and the number six green contractor in the world. We utilize our scale and the technical strength of our 
workforce  to  create  innovative  solutions  for  our  clients.  We  are  accelerating  investments  to  extend  our  capabilities,  including  the 
expansion of our digital capabilities to create innovative ways of delivering our work and solving the world’s most complex challenges. 
Clients are turning to us to create solutions to achieve their Environmental, Social, and Governance (ESG) objectives with a focus on 
sustainability and resilience initiatives, which include supporting the advancement of more energy efficient and less-carbon-intensive 
infrastructure. With our market leading technical capabilities, we are uniquely well suited to address these challenges. 

Our business focuses primarily on providing fee-based knowledge-based services. We primarily derive income from our ability 
to generate revenue and collect cash from our clients through the billing of our employees’ time spent on client projects and our ability 
to manage our costs. AECOM Capital primarily derives its income from real estate development sales and management fees.

During the first quarter of fiscal 2020, we reorganized our operating and reporting structure to better align with our ongoing 
professional services business. This reorganization better reflected our continuing operations after the sale of our Management Services 
segment,  the  sale  of  our  self-perform  at-risk  civil  infrastructure  and  power  construction  businesses,  and  the  sale  of  our  oil &  gas 
construction business. Our Management Services and self-perform at-risk construction businesses were part of our former Management 
Services segment and represented a substantial portion of the revenue of our former Construction Services segment, respectively. These 
businesses are classified as discontinued operations in all periods presented. 

We  report  our  continuing  business  through  three  segments,  each  of  which  is  described  in  further  detail  below:  Americas, 
International, and AECOM Capital (ACAP). Such segments are organized by the differing specialized needs of the respective clients 
and how we manage the business. We have aggregated various operating segments into our reportable segments based on their similar 
characteristics, including similar long-term financial performance, the nature of services provided, internal processes for delivering those 
services, and types of customers. 

•  Americas:  Planning, consulting, architectural and engineering design, construction management and program management 
services  to  public  and  private  clients  in  the  United  States,  Canada,  and  Latin  America  in  major  end  markets  such  as 
transportation, water, government, facilities, environmental, and energy. 

• 

International:  Planning, consulting, architectural and engineering design services and program management to public and 
private clients in Europe, the Middle East, India, Africa, and the Asia-Australia-Pacific regions in major end markets such 
as transportation, water, government, facilities, environmental, and energy. 

•  AECOM Capital (ACAP):  Primarily invests in and develops real estate projects.  

Our Americas and International Segments  

Our Americas and International segments are comprised of a broad array of services, generally provided on a fee-for-service 
basis.  These  services  include  advisory,  planning,  consulting,  architectural  and  engineering  design,  program  management  and 
construction management for public and private clients worldwide. For each of these services, our technical expertise includes civil 
engineering,  structural  engineering,  process  engineering,  mechanical  engineering,  geotechnical  systems  and  electrical  engineering, 
architectural, landscape and interior design, urban and regional planning, project economics, cost consulting and environmental, health 
and safety work.  

With  our  technical,  advisory  and  program  management  expertise,  we  are  able  to  provide  our  clients  a  broad  spectrum  of 
services. For example, within our water service offerings, we provide water, wastewater, water supply and water resource services, 
which are necessary in response to climate adaptation and resilience, drought mitigation and other environmental and social impact 
factors as part of major capital/infrastructure projects.  

In  addition,  our  industry  is  undergoing  a  digital  transformation,  and  we  are  investing  in  digital  capabilities  to  extend  our 
advantages, improve overall delivery, and create distinct solutions for clients that differentiate us from competitors and enhance our 
client experience. These investments include capturing the value of our libraries of data to build more efficient design processes, and 
innovative and more advanced solutions for increasingly complex challenges, where our digital suite of products are creating a more 
holistic approach to our work. 

Our services may be sequenced over multiple phases or multiple projects in the form of a program. For example, in the area of 
program  management  and  construction  management  services,  our  work  for  a  client  may  begin  with  a  small  consulting  or  planning 
contract, and may later develop into an overall management role for the project or a series of projects, which we refer to as a program. 

4 

 
Program and construction management contracts may employ small or large project teams and, in many cases, operate as an outsourcing 
arrangement with our staff located at the project site.

Our AECOM Capital Segment 

ACAP typically partners with investors and experienced developers as co-general partners. These partnerships may, but is not 
required  to,  enter  into  contracts  with  our  other  AECOM  affiliates  to  provide  design,  owners  engineer,  construction  management, 
development and operations and maintenance services for ACAP funded projects. ACAP development activity is conducted through 
joint ventures or subsidiaries that may be consolidated or unconsolidated for financial reporting purposes depending on the extent and 
nature of our ownership interest. In addition, in connection with the investment activities of ACAP, AECOM or an affiliate may provide 
guarantees of certain financial obligations, including guarantees for completion of projects, repayment of debt, environmental indemnity 
obligations, and other lender required guarantees. ACAP has focused on investing in co-general partner equity opportunities with high 
quality partners, primarily targeting “build-to-core” investments in the top U.S. markets across all property types. 

During  fiscal  2023,  we  initiated  a  process  to  explore  strategic  options  for  the  AECOM  Capital  business.  This  process  is 
consistent with our focus on our professional services business. AECOM Capital will continue to manage existing investment vehicles 
and investments in a manner consistent with their current obligations. 

Thinking and Acting Globally 

AECOM is at its best when we think and act globally. Our strategy is focused on setting a new standard of excellence in the 
professional services industry. First, our operating structure promotes greater connectivity and collaboration across our seven regions 
and five global business lines. We drive growth by prioritizing our core markets, leaning into our greatest strengths and ensuring our 
best talent and resources are focused on nurturing client relationships. We are transforming the way we deliver work through technology 

7 

 
and digital platforms improving the client experience and increasing efficiency. Lastly, we are building upon our position as a leading 
ESG company, unified by our purpose to deliver a better world. 

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 is at 
the core of what we do and how we operate — focusing on the environmental, social and governance impact 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 increasingly ambitious greenhouse gas emissions reduction targets. To this point, in fiscal 2022, we 
were  among  the  first  companies  globally  to  have  set  net  zero  emissions  reduction  targets  approved  by  the  Science  Based  Targets 
Initiative (SBTi), which are designed to exceed the goals of the Paris Agreement on climate change. These net zero emissions reduction 
goals include a near-term target to reduce Scope 1, 2 and 3 emissions by 50% by 2030 and a long-term target to reduce total emissions 
by 90% by 2040. These commitments build upon our commitments as a signatory to the UN Global Compact.  

In addition, we continue to invest in proprietary innovations and digital solutions. This includes a solution to combat globally 
pervasive emerging contaminants, such as our proprietary DE-FLUOROTM water treatment solution to destroy per and polyfluoroalkyl 
substances (PFAS) on-site. In addition, we are leading on decarbonization measurement, biodiversity impact and re-wilding through our 
innovative work at the National Capital Laboratory (NCL) in the U.K., where we are restoring 100 acres of forest and reintroducing lost 
species. Our work at the NCL won the 2022 Verdantix Innovation Excellence Award for Sustainability Strategy Implementation for 
success in analyzing and measuring biodiversity impact. 

We maintain an internal Global ESG Council to coordinate and drive our ESG initiatives across AECOM worldwide, and our 
Board 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.

Human Capital Management 

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  2023,  we  employed  approximately  52,000  persons,  of  whom 
approximately 18,000 were employed in the United States. Over 400 of our domestic employees are covered by collective bargaining 
agreements or by specific labor agreements, which expire upon completion of the relevant project. We believe that the quality and level 
of service that our professionals deliver are among the highest in our industry.  

We are committed to enhancing our position as a leading employer in our industry by attracting and retaining the best technical 
professionals in the world. Critical to our continued success is our ability to offer a compelling employee value proposition that promises 
competitive  pay  and  benefits,  an  inclusive  environment  that  supports  flexibility  and  well-being  and  encourages  collaboration  and 
innovation, and a shared commitment to technical excellence, continuous learning and career growth. This understanding informs our 
approach to managing our human capital resources. 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. We have taken and will continue to take critical steps to keep our 
people, clients and communities safe, including any necessary actions in response to local and global health crises. 

Equity, diversity and inclusion. We are committed to advancing equity, diversity and inclusion in our organization and within 
our industry. We build safe and respectful work environments where our employees are invited to bring their talents, backgrounds and 
expertise to bear on some of the world’s most complex problems and where every person has the opportunity to thrive personally and 
professionally. We are advancing efforts globally in four key areas: 1) Building a workforce reflective of the communities we serve 
through our recruitment efforts, building leadership accountability, and partnering with nonprofit organizations and universities to build 
the  talent  pipeline  for  the  future;  2) Enriching  communities  through  pro-bono  work,  volunteerism,  philanthropy  and  strategic 
partnerships;  3) Expanding  understanding  and  empathy  among  employees  through  employee  resource  groups,  ED&I  events  and 
celebrations,  and  family-friendly  benefit  policies;  and  4) Prioritizing  social  equity  and  impact  in  every  project  we  pursue  and  the 
innovative solutions we deliver. 

Freedom  to  Grow.  Freedom  to  Grow  is  our  global  framework  designed  to  support  employees  in  finding  the  balance  and 
flexibility they need to be their best and deliver for clients, and a key factor in our ability to attract and retain talent. Employees and 
managers can evaluate work schedules and locations and align on an arrangement that prioritizes client and team responsibilities while 

9 

 
 
supporting individual needs and includes three days a week in the office or at project sites as an expectation. Our Freedom to Grow 
program goes far beyond just when and where we work. We consider our people’s holistic experience, respecting diversity in work, 
communication and thinking styles. 

Workplace of the future. Drawing on the experiences of our teams and our clients during the pandemic, we developed a space 
and technology framework that allows for seamless connectivity between home offices, company offices and client sites, and a new 
global workplace design that accounts for reduced capacity requirements and prioritizes sustainability, collaboration and engagement. 
We are also advancing initiatives to enable the digital delivery of our work by establishing best practices and governance protocols for 
the digital reuse of core elements of the design process. 

Technical and professional development. Technical excellence is the foundation of our business—it’s how we harness the 
power of our teams’ technical skills and expertise to deliver high quality solutions for clients and communities we serve. We strive to 
be home to our industry's best technical minds — professionals who thrive in an environment that encourages their collaboration and 
innovation and celebrates great project and client outcomes. 

We have invested in a robust learning ecosystem that keeps our employees project-ready with 'on the job' technical training, 
future-ready  with  new  digital  tools,  thought  leadership  and  programs  that  inspire  innovation,  and  globally  connected  within  their 
technical practice and strategic partnerships. 

Our digital learning platform, AECOM University, delivers high-quality and personalized learning experiences, including our 
Global Technical Academies. Created by us for us, Academies deliver structured and self-directed technical training courses on key 

10 

 
 
 
global  topics,  practices  and  markets  that  are  relevant  to  our  business.  Our  Technical  Practice  Network  connects  nearly  20,000 
professionals every day in a global online community to enable networking, collaboration and problem solving. 

In  addition,  our  full  range  of  professional  development  programs,  called  Leadership  at  all  Levels,  enhance  business  and 
leadership  skills.  From  early  career  and  graduate  programs,  to  practical  manager  training,  and  executive  coaching  and  leadership 
development,  we  are  supporting  development  at  every  career  level.  These  programs  are  based  on  our  four  pillars  of  Leadership 
Capabilities, which outline the behaviors we want our leaders to demonstrate and exemplify for the collective success as an organization. 

Purpose and impact. As the world’s trusted infrastructure consulting firm and a leader in environmental, social and corporate 
governance (ESG), we are determined and well-positioned to deliver positive, impactful and Sustainable Legacies for our company, our 
communities and our planet. Through strategic nonprofit partnerships, pro-bono work, skills-based volunteering and philanthropy, 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 our pro-bono program, our technical experts partnered with nonprofit organizations in their local communities to provide 
critical design, engineering and infrastructure solutions. In addition, we have maintained our commitment to our enterprise strategic 
nonprofit partners – Engineers Without Borders and Water for People.

No single client accounted for 10% or more of our revenue in any of the past five fiscal years. Approximately 5%, 6%, and 8% 
of our revenue was derived through direct contracts with agencies of the U.S. federal government in the years ended September 30, 
2023, 2022, and 2021, respectively.  

Contracts 

The price provisions of the contracts we undertake can be grouped into several broad categories: cost-reimbursable contracts, 
guaranteed maximum price contracts, and fixed-price contracts. For the year ended September 30, 2023, our revenue was comprised of 
43%, 34%, and 23% cost-reimbursable, guaranteed maximum price, and fixed-price contracts, respectively.

Cost-Reimbursable Contracts 

Cost-reimbursable  contracts include  cost-plus fixed  fee,  cost-plus  fixed rate,  and  time-and-materials price  contracts. Under 
cost-plus contracts, we charge clients for our costs, including both direct and indirect costs, plus a negotiated fee or rate. We recognize 
revenues based on actual direct costs incurred and the applicable fixed rate or portion of the fixed fee earned as of the balance sheet 
date. Under time-and-materials price contracts, we negotiate hourly billing rates and charge clients based on the actual time we expend 
on  the  project.  In  addition,  clients  reimburse  us  for  materials  and  other  direct  incidental  expenditures,  including  payments  to 
subcontractors, incurred in connection with our performance under the contract. Time-and-material price contracts may also have a 
fixed-price element in the form of not-to-exceed or guaranteed maximum price provisions.  

Some cost-plus contracts provide for award fees or a penalty based on performance criteria in lieu of a fixed fee or fixed rate. 
Other  contracts  include  a  base  fee  component  plus  a  performance-based  award  fee.  In  addition,  we  may  share  award  fees  with 
subcontractors. We generally recognize revenue to the extent of costs actually incurred plus a proportionate amount of the fee expected 
to be earned. We take the award fee or penalty on contracts into consideration when estimating revenue and profit rates, and record 
revenue related to the award fees when there is sufficient information to assess anticipated contract performance and a significant reversal 
of the award fee is not probable. Once an award is received, the estimated or accrued fees are adjusted to the actual award amount. 

Some cost-plus contracts provide for incentive fees based on performance against contractual milestones. The amount of the 
incentive fees varies, depending on whether we achieve above, at, or below target results. We originally recognize revenue on these 
contracts based upon expected results. These estimates are revised when necessary based upon additional information that becomes 
available as the contract progresses. 

Guaranteed Maximum Price Contracts 

Guaranteed maximum price (GMP) contracts share many of the same contract provisions as cost-plus and fixed-price contracts. 
As with cost-plus contracts, clients are provided a disclosure of all project costs, and a lump sum percentage fee is separately identified. 
We provide clients with a guaranteed price for the overall project (adjusted for change orders issued by clients) and a schedule including 
the expected completion date. Cost overruns or costs associated with project delays in completion could generally be our responsibility. 
For many of our commercial or residential GMP contracts, the final price is generally not established until we have subcontracted a 
substantial percentage of the trade contracts with terms consistent with the master contract, and we have negotiated additional contract 
limitations,  such  as  waivers  of  consequential  damages  as  well  as  aggregate  caps  on  liabilities  and  liquidated  damages.  Revenue  is 
recognized for GMP contracts as project costs are incurred relative to total estimated project costs. 

Fixed-Price Contracts 

Fixed-price contracts include both lump-sum and fixed-unit price contracts. Under lump-sum contracts, we perform all the 
work under the contract for a specified price. Lump-sum contracts are typically subject to price adjustments if the scope of the project 
changes or unforeseen conditions arise. Under fixed-unit price contracts, we perform a number of units of work at an agreed price per 
unit with the total payment under the contract determined by the actual number of units delivered. Revenue is recognized for fixed-price 
contracts using the input method measured on a cost-to-cost basis as the Company believes this is the best measure of progress towards 
completion. 

Some of our fixed-price contracts require us to provide surety bonds or parent company guarantees to assure our clients that 
their  project  will  be  completed  in  accordance  with  the  terms  of  the  contracts  as  further  disclosed  in  Note  18—Commitments  and 
Contingencies. In such cases, we may require our primary subcontractors to provide similar performance bonds and guarantees and to 
be adequately insured, and we may flow down the terms and conditions set forth in our agreement on to our subcontractors. There may 
be risks associated with completing these projects profitably if we are not able to perform our services within the fixed-price contract 
terms. 

Joint Ventures 

Some of our larger contracts may operate under joint ventures or other arrangements under which we team with other reputable 
companies, typically companies with which we have worked for many years. This is often done where the scale of the project dictates 
such an arrangement or when we want to strengthen either our market position or our technical skills. 

12 

 
Backlog 

Backlog represents revenue we expect to realize for work completed by our consolidated subsidiaries and our proportionate 
share of work to be performed by unconsolidated joint ventures. Backlog is expressed in terms of gross revenue and, therefore, may 
include significant estimated amounts of third party or pass-through costs to subcontractors and other parties. We report transaction 
price allocated to remaining unsatisfied performance obligations (RUPO) of $21.9 billion, as described in Note 4, Revenue Recognition, 
in the notes to our consolidated financial statements. The most significant differences between our backlog and RUPO are backlog 
contains revenue we expect to record in the future where we have been awarded the work, but the contractual agreement has not yet 
been signed, unconsolidated joint venture backlog where we expect to realize income through equity earnings rather than revenue, and 
revenue related to service contracts that extend beyond the termination provision of those contracts, where RUPO requires us to assume 
the contract will be terminated at its earliest convenience. Accordingly, RUPO is $19.3 billion lower than backlog. For non-government 
contracts, our backlog includes future revenue at contract rates, excluding contract renewals or extensions that are at the discretion of 
the client. For contracts with a not-to-exceed maximum amount, we include revenue from such contracts in backlog to the extent of the 
remaining estimated amount. We calculate backlog without regard to possible project reductions or expansions or potential cancellations 
until such changes or cancellations occur. No assurance can be given that we will ultimately realize our full backlog. Backlog fluctuates 
due to the timing of when contracts are awarded and contracted and when contract revenue is recognized. Many of our contracts require 
us to provide services over more than one year. Our backlog for the year ended September 30, 2023 increased $1.0 billion, or 2.5%, to 
$41.2 billion as compared to $40.2 billion for the corresponding period last year, primarily due to an increase in our International design 
business.

Competition 

The  markets  we  serve  are  highly  fragmented  and  we  compete  with  a  large  number  of  regional,  national  and  international 
companies. We have numerous competitors, ranging from small private firms to multi-billion dollar companies, some of which have 
greater financial resources or that are more specialized and concentrate their resources in particular areas of expertise. The extent of our 
competition varies according to the particular markets and geographic area. The degree and type of competition we face is also influenced 
by the type and scope of a particular project. The technical and professional aspects of our services generally do not require large upfront 
capital expenditures and, therefore, provide limited barriers against new competitors. 

We believe that we are well positioned to compete in our markets because of our reputation, our cost effectiveness, our long-
term client relationships, our extensive network of offices, our employee expertise, and our broad range of services. In addition, as a 
result of our extensive national and international network, we are able to offer our clients localized knowledge and expertise, as well as 
the support of our worldwide professional staff. In addition, through investments in technology and innovation, we are able to bring 
advanced solutions to clients.

Seasonality 

We experience seasonal trends in our business. Our revenue is typically higher in the last half of the fiscal year. The fourth 
quarter of our fiscal year (July 1 to September 30) is typically our strongest quarter. We find that the U.S. federal government tends to 
authorize more work during the period preceding the end of our fiscal year, September 30. In addition, many U.S. state governments 
with fiscal years ending on June 30 tend to accelerate spending during their first quarter, when new funding becomes available. Further, 
our construction management revenue typically increases during the high construction season of the summer months. Within the United 
States, as well as other parts of the world, our business generally benefits from milder weather conditions in our fiscal fourth quarter. 
Our construction and project management services also typically expand during the high construction season of the summer months. 
The first quarter of our fiscal year (October 1 to December 31) is typically our lowest revenue quarter. The harsher weather conditions 
impact our ability to complete work in parts of North America and the holiday season schedule affects our productivity during this 
period. For these reasons, coupled with the number and significance of client contracts commenced and completed during a particular 
period, as well as the timing of expenses incurred for corporate initiatives, it is not unusual for us to experience seasonal changes or 
fluctuations in our quarterly operating results. 

Risk Management and Insurance 

Risk management is an integral part of our project management approach and our project execution process. We have an Office 
of Risk Management that reviews and oversees the risk profile of our operations through a tiered process of formal risk committees with 
the  highest-risk  pursuits  subject  to  vetting  at  each  tier.  Following  contract  execution,  and  commencement  of  delivery,  projects  are 
monitored via a formal monthly or quarterly project-review process designed to ensure project performance and risk mitigation. Also, 
pursuant to our internal delegations of authority, a group of senior members of our risk management team evaluates risk through internal 
risk analyses of higher-risk projects, contracts or other business decisions. We maintain insurance covering professional liability and 
claims involving bodily injury and property damage, among other coverages. Wherever possible, we endeavor to eliminate or reduce 
the risk of loss on a project through the use of quality assurance/control, risk management, workplace safety and similar methods. 

Regulations 

Our business is impacted by environmental, health and safety, government procurement, anti-bribery and other government 

regulations and requirements. Below is a summary of some of the significant regulations that impact our business. 

Environmental,  Health  and  Safety.    Our  business  involves  the  planning,  design,  program  management,  construction 
management, and operations and maintenance at various project sites, including, but not limited to, nuclear facilities, hazardous waste 
and Superfund sites, hydrocarbon production, distribution and transport sites, and other infrastructure-related facilities. We also regularly 
perform work in and around sensitive environmental areas, such as rivers, lakes and wetlands. 

Significant fines, penalties and other sanctions may be imposed for non-compliance with environmental and health and safety 
laws and regulations, and some laws provide for joint and several strict liabilities for remediation of releases of hazardous substances, 
rendering a person liable for environmental damage, without regard to negligence or fault on the part of such person. These laws and 
regulations may expose us to liability arising out of the conduct of operations or conditions caused by others, or for our acts that were 
in compliance with all applicable laws at the time these acts were performed. For example, there are a number of governmental laws 
that  strictly  regulate  the  handling,  removal,  treatment,  transportation  and  disposal  of  toxic  and  hazardous  substances,  such  as  the 
Comprehensive Environmental Response Compensation and Liability Act of 1980, and comparable national and state laws, that impose 
strict, joint and several liabilities for the entire cost of cleanup, without regard to whether a company knew of or caused the release of 
hazardous substances. In addition, some environmental regulations can impose liability for the entire clean-up upon owners, operators, 
generators, transporters and other persons arranging for the treatment or disposal of such hazardous substances related to contaminated 
facilities or project sites. Other federal environmental, health and safety laws affecting us include, but are not limited to, the Resource 
Conservation  and  Recovery  Act,  the  National  Environmental  Policy  Act,  the  Clean  Air  Act,  the  Clean  Air  Mercury  Rule,  the 
Occupational Safety and Health Act, the Toxic Substances Control Act, and the Superfund Amendments and Reauthorization Act, as 
well as other comparable national and state laws. Liabilities related to environmental contamination or human exposure to hazardous 
substances, comparable national and state laws or a failure to comply with applicable regulations could result in substantial costs to us, 
including cleanup costs, fines and civil or criminal sanctions, third-party claims for property damage or personal injury, or cessation of 
remediation activities. 

14 

 
Some of our business operations are covered by Public Law 85-804, which provides for indemnification by the U.S. federal 
government against claims and damages arising out of unusually hazardous or nuclear activities performed at the request of the U.S. 
federal government. Should public policies and laws change, however, U.S. federal government indemnification may not be available 
in the case of any future claims or liabilities relating to hazardous activities that we undertake to perform. 

Government  Procurement.    The  services  we  provide  to  the  U.S.  federal  government  are  subject  to  Federal  Acquisition 
Regulation, the Truth in Negotiations Act, Cost Accounting Standards, the Services Contract Act, False Claims Act, export controls 
rules and Department of Defense (DOD) security regulations, as well as many other laws and regulations. These laws and regulations 
affect how we transact business with our clients and, in some instances, impose additional costs on our business operations. A violation 
of specific laws and regulations could lead to fines, contract termination or suspension of future contracts. Our government clients can 
also terminate, renegotiate, or modify any of their contracts with us at their convenience; and many of our government contracts are 
subject to renewal or extension annually. 

Anti-Bribery and other regulations.  We are subject to the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act of 2010, 
and similar anti-bribery laws, which generally prohibit companies and their intermediaries from making improper payments to foreign 
government officials for the purpose of obtaining or retaining business. To the extent we export technical services, data and products 
outside of the U.S., we are subject to U.S. and international laws and regulations governing international trade and exports, including, 
but not limited to, the International Traffic in Arms Regulations, the Export Administration Regulations, and trade sanctions against 
embargoed  countries. We  provide services  to  the  DOD  and other defense-related  entities  that often require  specialized professional 
qualifications and security clearances. In addition, as engineering design services professionals, we are subject to a variety of local, 
state, federal, and foreign licensing and permit requirements and ethics rules. 

Raw Materials 

We purchase most of the raw materials and components necessary to operate our business from numerous sources. However, 
the price and availability of raw materials and components may vary from year to year due to customer demand, production capacity, 
market conditions, and material shortages. While we do not currently foresee the lack of availability of any particular raw materials in 
the near term, prolonged unavailability of raw materials necessary to our projects and services or significant price increases for those 
raw materials could have a material adverse effect on our business in the near term. 

Government Contracts 

Generally, our government contracts are subject to renegotiation or termination of contracts or subcontracts at the discretion of 

the U.S. federal, state or local governments, and national governments of other countries. 

Trade Secrets and Other Intellectual Property 

We  rely  principally  on  trade  secrets,  confidentiality  policies  and  other  contractual  arrangements  to  protect  much  of  our 

intellectual property.

ITEM 1A.  RISK FACTORS 

We operate in a changing global environment that involves numerous known and unknown risks and uncertainties that could 
materially adversely affect our operations. The risks described below highlight some of the factors that have affected, and in the future 
could affect our operations. Additional risks we do not yet know of or that we currently believe are immaterial may also affect our 
business  operations.  If  any  of  the  events  or  circumstances  described  in  the  following  risks  actually  occurs,  our  business,  financial 
condition or results of operations could be materially adversely affected. 

Risks Related to Our Markets, Customers and Business 

Our industry is highly competitive, and we may be unable to compete effectively, which could result in reduced revenue, profitability 
and market share. 

We are engaged in a highly competitive business. The markets we serve are highly fragmented and we compete with a large 
number of regional, national and international companies. These competitors may have greater financial and other resources than we 
do. Others are smaller and more specialized, and concentrate their resources in particular areas of expertise. The extent of our competition 
varies according to the particular markets and geographic area. In addition, the technical and professional aspects of some of our services 
generally do not require large upfront capital expenditures and provide limited barriers against new competitors. 

The degree and type of competition we face is also influenced by the type and scope of a particular project. Our clients make 
competitive determinations based upon qualifications, experience, performance, reputation, technology, customer relationships, price 
and ability to provide the relevant services in a timely, safe and cost-efficient manner. Increased competition may result in our inability 
to win bids for future projects, increased margin pressure and loss of revenue, profitability and market share. 

Our ability to compete in our industry will be harmed if we do not retain the continued services of our senior management and key 
technical personnel. 

We  rely  heavily  upon  the  expertise  and  leadership  of  our  people.  There  is  strong  competition  for  qualified  technical  and 
management personnel in the sectors in which we compete. We may not be able to continue to attract and retain qualified technical and 
management personnel, such as engineers, architects and project managers, who are necessary for the development of our business or 
to replace qualified personnel in the timeframe demanded by our clients. Also, some of our personnel hold government granted eligibility 
that may be required to obtain government projects. Loss of the services of, or failure to recruit, senior management or key technical 
personnel could impact the long-term performance of the Company and limit our ability to successfully complete existing projects and 
compete for new projects. 

Demand for our services is cyclical and vulnerable to sudden economic downturns and reductions in government and private industry 
spending. If economic conditions remain uncertain and/or weaken, our revenue and profitability could be adversely affected. 

Demand  for  our  services  is  cyclical  and  may  be  vulnerable  to  sudden  economic  downturns,  interest  rate  fluctuations  and 
reductions in government and private industry spending that result in clients delaying, curtailing or canceling proposed and existing 
projects. Where economies are weakening, our clients may demand more favorable pricing or other terms while their ability to pay our 
invoices or to pay them in a timely manner may be adversely affected. Our government clients may face budget deficits that prohibit 
them from funding proposed and existing projects. If economic conditions remain uncertain and/or weaken and/or government spending 
is reduced, our revenue and profitability could be materially adversely affected.  

We depend on long-term government contracts, some of which are only funded on an annual basis. If appropriations for funding 
are not made in subsequent years of a multiple-year contract, we may not be able to realize all of our anticipated revenue and profits 
from that project. 

A  substantial  portion  of  our  revenue  is  derived  from  contracts  with  agencies  and  departments  of  national,  state,  and  local 
governments. During fiscal 2023 and 2022, approximately 43% and 41%, respectively, of our revenue was derived from contracts with 
government entities.  

Most government contracts are subject to such government’s budgetary approval process. Legislatures typically appropriate 
funds for a given program on an annual basis, even though contract performance may take more than one year. In addition, public-
supported financing such as state and local municipal bonds may be only partially raised to support existing infrastructure projects. As 

16 

 
a result, at the beginning of a program, the related contract is only partially funded, and additional funding is normally committed only 
as  appropriations  are  made  in  each  fiscal  year.  These  appropriations,  and  the  timing  of  payment  of  appropriated  amounts,  may  be 
influenced by, among other things, the state of the economy, an extended government shutdown, competing priorities for appropriation, 
changes  in  administration or  control  of  legislatures,  and  the  timing  and amount of  tax receipts  and  the  overall  level  of  government 
expenditures. Similarly, the impact of an economic downturn on governments may make it more difficult for them to fund infrastructure 
projects. If appropriations are not made in subsequent years on our government contracts, then we will not realize all of our potential 
revenue and profit from those contracts.  

If we are unable to win or renew government contracts during regulated procurement processes, our operations and financial results 
would be harmed. 

Government contracts are awarded through a regulated procurement process. The federal government has awarded multi-year 
contracts with pre-established terms and conditions, such as indefinite delivery contracts, that generally require those contractors that 
have previously been awarded the indefinite delivery contract to engage in an additional competitive bidding process before a task order 
is issued. The federal government has also awarded federal contracts based on a low-price, technically acceptable criteria emphasizing 
price over qualitative factors, such as past performance. As a result of these competitive pricing pressures, our profit margins on future 
federal contracts may be reduced and may require us to make sustained efforts to reduce costs in order to realize profits under government 
contracts. If we are not successful in reducing the amount of costs we incur, our profitability on government contracts will be negatively 
impacted. In addition, we may not be awarded government contracts because of existing government policies designed to protect small 
businesses  and  under-represented  minority  contractors.  Our  inability  to  win  or  renew  government  contracts  during  regulated 
procurement processes could harm our operations and reduce our profits and revenues. 

Governmental agencies may modify, curtail or terminate our contracts at any time prior to their completion and, if we do not replace 
them, we may suffer a decline in revenue. 

Most government contracts may be modified, curtailed or terminated by the government either at its discretion or upon the 
default of the contractor. If the government terminates a contract at its discretion, then we typically are able to recover only costs incurred 
or committed, settlement expenses and profit on work completed prior to termination, which could prevent us from recognizing all of 
our potential revenue and profits from that contract. In addition, for some assignments, the U.S. government may attempt to “insource” 
the services to government employees rather than outsource to a contractor. If a government terminates a contract due to our default, we 
could be liable for excess costs incurred by the government in obtaining services from another source. 

17 

 
Our contracts with governmental agencies are subject to audit, which could result in adjustments to reimbursable contract costs or, 
if we are charged with wrongdoing, possible temporary or permanent suspension from participating in government programs. 

Our books and records are subject to audit by the various governmental agencies we serve and their representatives. These 
audits can result in adjustments to the amount of contract costs we believe are reimbursable by the agencies and the amount of our 
overhead costs allocated to the agencies. If such matters are not resolved in our favor, they could have a material adverse effect on our 
business. In addition, if one of our subsidiaries is charged with wrongdoing as a result of an audit, that subsidiary, and possibly our 
company as a whole, could be temporarily suspended or could be prohibited from bidding on and receiving future government contracts 
for a period of time. Furthermore, as a government contractor, we are subject to an increased risk of investigations, criminal prosecution, 
civil fraud actions, whistleblower lawsuits, and other legal actions and liabilities to which purely private sector companies are not, the 
results of which could materially adversely impact our business. For example, from time to time we may be subject to qui tam lawsuits, 
which typically allege that we have made false statements or certifications in connection with claims for payment, or improperly retained 
overpayments,  from  the  government.  These  suits  may  remain  under  seal  (and  hence,  be  unknown  to  us) for  some  time  while  the 
government decides whether to intervene on behalf of the qui tam plaintiff. 

Risks Related to our Capital Structure 

The agreements governing our debt contain a number of restrictive covenants which will limit our ability to finance future operations, 
acquisitions or capital needs or engage in other business activities that may be in our interest. 

The Credit Agreement (defined below) and the indentures governing our debt contain a number of significant covenants that 
impose operating and other restrictions on us and our subsidiaries. Such restrictions affect or will affect and, in many respects, limit or 
prohibit, among other things, our ability and the ability of some of our subsidiaries to: 

• 

• 

• 

• 

• 

incur additional indebtedness; 

create liens; 

pay dividends and make other distributions in respect of our equity securities; 

redeem or repurchase our equity securities; 

distribute excess cash flow from foreign to domestic subsidiaries; 

•  make investments or other restricted payments; 

• 

• 

• 

sell assets; 

enter into transactions with affiliates; and 

effect mergers or consolidations. 

In addition, our Credit Agreement requires us to comply with a consolidated interest coverage ratio and consolidated leverage 
ratio. Our ability to comply with these ratios may be affected by events beyond our control. These restrictions could limit our ability to 
plan for or react to market or economic conditions or meet capital needs or otherwise restrict our activities or business plans, and could 
adversely affect our ability to finance our operations, acquisitions, investments or strategic alliances or other capital needs or to engage 
in other business activities that would be in our interest. A breach of any of these covenants or our inability to comply with the required 
financial ratios could result in a default under our debt instruments. If an event of default occurs, our creditors could elect to: 

• 

• 

• 

declare all borrowings outstanding, together with accrued and unpaid interest, to be immediately due and payable; 

require us to apply all of our available cash to repay the borrowings; or 

prevent us from making debt service payments on our borrowings. 

18 

 
If we were unable to repay or otherwise refinance these borrowings when due, the applicable creditors could sell the collateral 
securing  some  of  our  debt  instruments,  which  constitutes  substantially  all  of  our  domestic  and  foreign,  wholly  owned  subsidiaries’ 
assets. 

Our  variable  rate  indebtedness  subjects  us  to  interest  rate  risk,  which  could  cause  our  debt  service  obligations  to  increase 
significantly. 

Borrowings under our Credit Agreement are at variable rates of interest and expose us to interest rate risk. In March 2022, the 
Federal Reserve began and it has continued, and is expected to continue, to raise interest rates in an effort to curb inflation. As interest 
rates increase, our debt service obligations on the variable rate indebtedness will increase even though the amount borrowed remains 
the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. A 
1.00% increase in such interest rates would increase total interest expense under our Credit Agreement for the year ended September 30, 
2023 by $8.6 million, including the effect of our interest rate swap and interest rate cap agreements. We may, from time to time, enter 
into additional interest rate swaps that involve the exchange of floating for fixed rate interest payments in order to reduce interest rate 
volatility. However, we may not maintain interest rate swaps with respect to all of our variable rate indebtedness, and any swaps we 
enter into may not fully mitigate our interest rate risk and could be subject to credit risk themselves. 

If we are unable to continue to access credit on acceptable terms, our business may be adversely affected. 

The changing nature of the global credit markets could make it more difficult for us to access funds, refinance our existing 
indebtedness, enter into agreements for uncommitted debt bond facilities and new indebtedness, replace our existing revolving and term 
credit agreements or obtain funding through the issuance of our securities. We use credit facilities to support our working capital and 
other needs. There is no guarantee that we can continue to renew our credit facility on terms as favorable as those in our existing credit 
facility and, if we are unable to do so, our costs of borrowing and our business may be adversely affected. 

Risks Related to our International Operations 

Our operations worldwide expose us to legal, political and economic risks in different countries as well as currency exchange rate 
fluctuations and impacts from inflation that could harm our business and financial results. 

During  fiscal  2023,  revenue  attributable  to  our  services  provided  outside  of  the  United  States  to  non-U.S.  clients  was 

approximately 29% of our total revenue. There are risks inherent in doing business internationally, including: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

the ongoing conflict between Russia and Ukraine, which has resulted in the imposition by the U.S. and other nations of 
restrictive actions against Russia, Belarus and certain banks, companies and individuals; 

imposition of governmental controls and changes in laws, regulations or policies; 

political and economic instability, including in the Middle East;  

civil unrest, acts of terrorism, force majeure, war, or other armed conflict; 

changes in U.S. and other national government trade policies affecting the markets for our services, such as retaliatory 
tariffs between the United States and China; 

political unrest in Hong Kong where we have a significant presence; 

impact of the Covid-19 pandemic and its related economic impacts; 

increases in the consumer price index and interest rates; 

changes in regulatory practices, tariffs and taxes; 

potential non-compliance with a wide variety of laws and regulations, including anti-corruption, export control and anti-
boycott laws and similar non-U.S. laws and regulations; 

19 

 
• 

• 

• 

changes in labor conditions; 

logistical and communication challenges; and 

currency exchange rate fluctuations, devaluations and other conversion restrictions. 

Any of these factors could have a material adverse effect on our business, results of operations or financial condition. 

We  operate  in  many  different  jurisdictions  and  we  could  be  adversely  affected  by  legislative  actions  of  governments,  as  well  as 
violations of the U.S. Foreign Corrupt Practices Act and similar worldwide anti-corruption laws. 

The U.S. Foreign Corrupt Practices Act (FCPA) and similar worldwide anti-corruption laws, including the U.K. Bribery Act 
of 2010, generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of 
obtaining or retaining business. Our internal policies mandate compliance with these anti-corruption laws, including the requirements 
to maintain accurate information and internal controls which may fall within the purview of the FCPA, its books and records provisions 
or its anti-bribery provisions. We operate in many parts of the world that have experienced governmental corruption to some degree; 
and, in some circumstances, strict compliance with anti-corruption laws may conflict with local customs and practices. Despite our 
training and compliance programs, we cannot assure that our internal control policies and procedures always will protect us from reckless 
or  criminal  acts  committed  by  our  employees  or  agents.  In  addition,  from  time  to  time,  government  investigations  of  corruption  in 
construction-related  industries  affect us  and  our peers. Violations  of  these  laws, or  allegations of  such violations, could disrupt our 
business and result in a material adverse effect on our results of operations or financial condition. 

The Building Safety Act, the primary legislation which introduces a new framework for the regulation of the UK construction 
industry,  became  law  on  April 28,  2022  with  certain  provisions  coming  into  force  on  June 28,  2022  and  remaining  provisions  and 
secondary legislation to follow. The Act extends liability periods for some historical defects in residential properties completed prior to 
2022, creates a new government regulatory body responsible for building safety and new legal obligations regarding building safety, 
reallocates the risk related to design and construction, and requires the development of a more stringent regulatory regime for select 
buildings. The new legislation may result in new risk, regulatory and cost challenges for our United Kingdom and global operations. 

Any of these events could adversely affect our United Kingdom, European operations and overall business and financial results. 

We work in international locations where there are high security risks, which could result in harm to our employees and contractors 
or material costs to us. 

Some of our services are performed in high-risk locations, such as the Middle East, Africa, and Southeast Asia, where the 
location is suffering from political, social or economic problems, or war or civil unrest. In those locations where we have employees or 
operations, we may incur material costs to maintain the safety of our personnel. Despite these precautions, the safety of our personnel 
in these locations may continue to be at risk. Acts of terrorism and threats of armed conflicts in or around various areas in which we 
operate could limit or disrupt markets and our operations, including disruptions resulting from the evacuation of personnel, cancellation 
of contracts, or the loss of key employees, contractors or assets. 

Risks Related to Our Operations and Technology 

Many of our project sites are inherently dangerous workplaces. Failure to maintain safe work sites and equipment could result in 
environmental disasters, employee deaths or injuries, reduced profitability, the loss of projects or clients and possible exposure to 
litigation. 

Our project sites often put our employees and others in close proximity with mechanized equipment, moving vehicles, chemical 
and manufacturing processes, and highly regulated materials. On some project sites, we may be responsible for safety and, accordingly, 
we  have  an  obligation  to  implement  effective  safety  procedures.  If  we  fail  to  implement  these  procedures  or  if  the  procedures  we 
implement are ineffective, we may suffer the loss of or injury to our employees, as well as expose ourselves to possible litigation. As a 
result, our failure to maintain adequate safety standards and equipment could result in reduced profitability or the loss of projects or 
clients, and could have a material adverse impact on our business, financial condition, and results of operations. 

20 

 
Cybersecurity threats, information technology systems outages and data privacy incidents could adversely harm our business. 

We  may  experience  errors, outages,  or  delays  of  service  in  our  information  technology  systems,  which  could significantly 
disrupt our operations, impact our clients and employees, damage our reputation, and result in litigation and regulatory fines or penalties. 
Various  privacy  and  securities  laws  pertaining  to  client  and  employee  data  usage  require  us  to  manage  and  protect  sensitive  and 
proprietary information. For example, the European’s Union General Data Protection Regulation extends the scope of the European 
Union data protection laws to all companies processing data of European Union residents, regardless of the company’s location. In 
addition, the California Consumer Privacy Act increased the penalties for data privacy incidents. 

We face threats to our information technology systems, including unauthorized access, computer hackers, computer viruses, 
malicious  code,  cyber-attacks,  phishing  and  other  cybersecurity  problems  and  system  disruptions,  including  possible  unauthorized 
access  to  our  and  our  clients’  proprietary  information.  We  rely  on  industry-accepted  security  measures  and  technology  to  securely 
maintain all proprietary information on our information technology systems. In the ordinary course of business, we have been targeted 
by malicious cyber-attacks. Anyone who circumvents our security measures could misappropriate proprietary information, including 
information regarding us, our employees and/or our clients, or cause interruptions in our operations. Although we devote significant 
resources to our cybersecurity programs and have implemented security measures to protect our systems and to prevent, detect and 
respond to cybersecurity incidents, there can be no assurance that our efforts will prevent these threats. As these security threats continue 
to evolve, we may be required to devote additional resources to protect, prevent, detect and respond against system disruptions and 
security breaches. 

We  also  rely  in  part  on  third-party  software  and  information  technology  vendors  to  run  our  critical  accounting,  project 
management and financial information systems. We depend on our software and information technology vendors to provide long-term 
software and hardware support for our information systems. Our software and information technology vendors may decide to discontinue 
further development, integration or long-term software and hardware support for our information systems, in which case we may need 
to abandon one or more of our current information systems and migrate some or all of our accounting, project management and financial 
information to other systems, thus increasing our operational expense, as well as disrupting the management of our business operations. 

Any of these events could damage our reputation and have a material adverse effect on our business, financial condition, results 
of operations and cash flows. Furthermore, while we maintain insurance that specifically covers these attacks, our coverage may not 
sufficiently cover all types of losses or claims that may arise. 

Risks Related to Contracts and Joint Ventures 

Our business and operating results could be adversely affected by losses under fixed-price or guaranteed maximum price contracts. 

Fixed-price  contracts  require  us  to  either  perform  all  work  under  the  contract  for  a  specified  lump-sum  or  to  perform  an 
estimated number of units of work at an agreed price per unit, with the total payment determined by the actual number of units performed. 
In  addition,  we  may  enter  guaranteed  maximum  price  contracts  where  we  guarantee  a  price  or  delivery  date.  For  the  year  ended 
September 30, 2023, our revenue was comprised of 43%, 34%, and 23% cost-reimbursable, guaranteed maximum price, and fixed-price 
contracts,  respectively.  Fixed-price  contracts  expose  us  to  a  number  of  risks  not  inherent  in  cost-reimbursable  contracts,  including 
underestimation  of  costs,  ambiguities  in  specifications,  unforeseen  increases  in  or  failures  in  estimating  the  cost  of  raw  materials, 
equipment or labor, increased costs as a result of inflation, problems with new technologies, delays beyond our control, fluctuations in 
profit margins, failures of subcontractors to perform and economic or other changes that may occur during the contract period. United 
States and foreign trade policy actions and tariffs such as the 2018 tariffs on steel and aluminum imports in the United States could 
affect the profitability of our fixed-price construction projects. Losses under fixed-price or guaranteed contracts could be substantial and 
adversely impact our results of operations. 

21 

 
Our failure to meet contractual schedule or performance requirements that we have guaranteed could adversely affect our operating 
results. 

In some circumstances, we can incur liquidated or other damages if we do not achieve project completion by a scheduled date. 
If we or an entity for which we have provided a guarantee fails to complete the project as scheduled and the matter cannot be satisfactorily 
resolved with the client, we may be responsible for cost impacts to the client resulting from any delay or the cost to complete the project. 
Our  costs  generally  increase  from  schedule  delays  and/or  could  exceed  our  projections  for  a  particular  project.  In  addition,  project 
performance can be affected by a number of factors beyond our control, including unavoidable delays from governmental inaction, 
public opposition, inability to obtain financing, weather conditions, unavailability of vendor materials, changes in the project scope of 
services  requested  by  our  clients,  industrial  accidents,  environmental  hazards,  labor  disruptions,  pandemics  including  the  current 
coronavirus, and other factors. Material performance problems for existing and future contracts could cause actual results of operations 
to differ from those anticipated by us and also could cause us to suffer damage to our reputation within our industry and client base. 

We may not be able to maintain adequate surety and financial capacity necessary for us to successfully bid on and win contracts. 

In line with industry practice, we are often required to provide surety bonds, standby letters of credit or corporate guarantees 
to our clients that indemnify them should our affiliate fail to perform its obligations under the terms of a contract. As of September 30, 
2023 and September 30, 2022, we were contingently liable for $4.6 billion and $4.4 billion, respectively, in issued surety bonds primarily 
to support project execution and we had outstanding letters of credit totaling $883.3 million and $644.7 million, respectively. A surety 
may issue a performance or payment bond to guarantee to the client that our affiliate will perform under the terms of a contract. If our 
affiliate fails to perform under the terms of the contract, then the client may demand that the surety or another corporate affiliate provide 
the contracted services. In addition, we would typically have obligations to indemnify the surety for any loss incurred in connection 
with the bond. If a surety bond or a letter of credit is required for a particular project and we are unable to obtain an appropriate surety 
bond or letter of credit, we may not be able to pursue that project, which in turn could have a material adverse impact on our business, 
financial condition, results of operations, and cash flows.  

We conduct a portion of our operations through joint venture entities, over which we may have limited control. 

Approximately 14% of our fiscal 2023 revenue was derived from our operations through joint ventures or similar partnership 
arrangements, where control may be shared with unaffiliated third parties. As with most joint venture arrangements, differences in views 
among the joint venture participants may result in delayed decisions or disputes. We also cannot control the actions of our joint venture 
partners and we typically have joint and several liability with our joint venture partners under the applicable contracts for joint venture 
projects. These factors could potentially adversely impact the business and operations of a joint venture and, in turn, our business and 
operations. 

Operating through joint ventures in which we are minority holders results in us having limited control over many decisions 
made with respect to projects and internal controls relating to projects. Sales of our services provided to our unconsolidated joint ventures 
were approximately 2% of our fiscal 2023 revenue. We generally do not have control of these unconsolidated joint ventures. These joint 
ventures may not be subject to the same requirements regarding internal controls and internal control over financial reporting that we 
follow. As a result, internal control problems may arise with respect to these joint ventures, which could have a material adverse effect 
on our financial condition and results of operations and could also affect our reputation. 

We participate in joint ventures where we provide guarantees and may be adversely impacted by the failure of the joint venture or its 
participants to fulfill their obligations. 

We have investments in and commitments to joint ventures with unrelated parties, including in connection with construction 
services, government services, and the investment activities of ACAP. For example, real estate and infrastructure joint ventures are 
inherently risky and may result in future losses since real estate markets are impacted by economic trends and government policies that 
we do not control. These joint ventures from time to time may borrow money to help finance their activities and, in some circumstances, 
we are required to provide guarantees of obligations of our affiliated entities. In addition, in connection with the investment activities of 
ACAP,  we  provide  guarantees  of  obligations,  including  guarantees  for  completion  of  projects,  repayment  of  debt,  environmental 
indemnity obligations and other lender required guarantees.  

22 

 
AECOM Capital’s real estate development and investment activities are inherently risky and may result in a future loss. 

ACAP’s real estate business involves managing, sponsoring, investing in and developing commercial real estate projects and 
joint ventures (Real Estate Joint Ventures) that are inherently risky and may result in future losses based on factors beyond our control, 
including economic trends, government policies and competition. Our SEC-registered investment adviser jointly manages and sponsors 
the AECOM-Canyon Equity Fund, L.P. (the “Fund”), in which the Company indirectly holds an equity interest and which also invests 
in and develops Real Estate Joint Ventures on behalf of its investors. Real Estate Joint Ventures rely on substantial amounts of third 
party borrowing to finance their development activities and the lenders of such financings typically require AECOM or an affiliate to 
provide completion guarantees, repayment guarantees, environmental indemnities and other lender required credit support guarantees 
to secure the Real Estate Joint Ventures financing. AECOM’s provision of lender guarantees is contingent upon the Real Estate Joint 
Ventures meeting AECOM’s underwriting criteria, which include an affiliate of AECOM acting as either the construction manager at 
risk or the owner’s representative for the project. Although the Fund and such Real Estate Joint Ventures have reserves that will be used 
to share any cost overruns of the Real Estate Joint Ventures, if such reserves are depleted, then AECOM may be required to make 
support  payments  to  fund  non-budgeted  cost  overruns  on  behalf  of  the  Fund  (but  not  on  behalf  of  the  Fund’s  co-partner  or  any 
unaffiliated limited partners of the Real Estate Joint Ventures). Some of the Fund’s limited partners may be permitted to make additional 
equity co-investments in certain Real Estate Joint Ventures for which AECOM will provide support payments on behalf of the limited 
partner co-investor in the event of a cost overrun of the Real Estate Joint Ventures after additional specific reserves have been depleted.  

Risks Related to Laws and Regulations 

Misconduct by our employees, subcontractors, partners or consultants or our failure to comply with laws or regulations applicable 
to our business could cause us to lose customers or lose our ability to contract with government agencies.  

As  a  government  contractor,  misconduct,  fraud  or  other  improper  activities  caused  by  our  employees’,  subcontractors’, 
partners’  or  consultants’  failure  to  comply  with  laws  or  regulations  could  have  a  significant  negative  impact  on  our  business  and 
reputation. Such misconduct could include the failure to comply with procurement regulations, environmental regulations, regulations 
regarding the protection of sensitive government information, legislation regarding the pricing of labor and other costs in government 
contracts, regulations on lobbying or similar activities, and anti-corruption, anti-competition, export control and other applicable laws 
or regulations. Our failure to comply with applicable laws or regulations, misconduct by any of our employees, subcontractors, partners 
or  consultants,  or  our  failure  to  make  timely  and  accurate  certifications  to  government  agencies  regarding  misconduct  or  potential 
misconduct could subject us to fines and penalties, loss of government granted eligibility, cancellation of contracts and suspension or 
debarment from contracting with government agencies, any of which may adversely affect our business.  

We may be subject to substantial liabilities under environmental laws and regulations. 

Our  services  are  subject  to  numerous  environmental  protection  laws  and  regulations  that  are  complex  and  stringent.  Our 
business involves in part the planning, design, program management, construction management, and operations and maintenance at 
various sites, including but not limited to, nuclear facilities, hazardous waste and Superfund sites, hydrocarbon production, distribution 
and transport sites, and other infrastructure-related facilities. We also regularly perform work in and around sensitive environmental 
areas,  such  as  rivers,  lakes  and  wetlands.  In  addition,  we  have  contracts  in  support  of  U.S.  federal  government  entities  to  destroy 
hazardous materials, including chemical agents and weapons stockpiles, as well as to decontaminate and decommission nuclear facilities. 
These activities may require us to manage, handle, remove, treat, transport and dispose of toxic or hazardous substances. We also own 
and operate several properties in the U.S. and Canada that have been used for the storage and maintenance of construction equipment. 
In the conduct of operations on these properties, and despite precautions having been taken, it is possible that there have been accidental 
releases of individually relatively small amounts of fuel, oils, hydraulic fluids and other fluids while storing or servicing this equipment. 
Such accidental releases though individually relatively small may have accumulated over time. Past business practices at companies that 
we have acquired may also expose us to future unknown environmental liabilities. 

23 

 
Significant fines, penalties and other sanctions may be imposed for non-compliance with environmental laws and regulations, 
and some environmental laws provide for joint and several strict liabilities for remediation of releases of hazardous substances, rendering 
a person liable for environmental damage, without regard to negligence or fault on the part of such person. These laws and regulations 
may expose us to liability arising out of the conduct of operations or conditions caused by others, or for our acts that were in compliance 
with  all  applicable  laws  at  the  time  these  acts  were performed.  For  example,  there  are  a  number  of  governmental  laws  that  strictly 
regulate  the  handling,  removal,  treatment,  transportation  and  disposal  of  toxic  and  hazardous  substances,  such  as  Comprehensive 
Environmental  Response  Compensation  and  Liability  Act  of  1980,  and  comparable  state  laws,  that  impose  strict,  joint  and  several 
liabilities for the entire cost of cleanup, without regard to whether a company knew of or caused the release of hazardous substances. In 
addition, some environmental regulations can impose liability for the entire cleanup upon owners, operators, generators, transporters 
and other persons arranging for the treatment or disposal of such hazardous substances related to contaminated facilities or project sites. 
Other federal environmental, health and safety laws affecting us include, but are not limited to, the Resource Conservation and Recovery 
Act, the National Environmental Policy Act, the Clean Air Act, the Clean Air Mercury Rule, the Occupational Safety and Health Act, 
the Toxic Substances Control Act and the Superfund Amendments and Reauthorization Act and the Energy Reorganization Act of 1974, 
as well as other comparable national and state laws. Liabilities related to environmental contamination or human exposure to hazardous 
substances, or a failure to comply with applicable regulations could result in substantial costs to us, including cleanup costs, fines and 
civil  or  criminal  sanctions,  third-party  claims  for  property  damage  or  personal  injury  or  cessation  of  remediation  activities.  Our 
continuing work in the areas governed by these laws and regulations exposes us to the risk of substantial liability. 

Risks Related to Climate Change 

Climate change, natural disasters and related environmental issues could have a material adverse impact on us. 

Climate-related events, such as an increase in frequency and severity of storms, floods, wildfires, droughts, hurricanes, freezing 
conditions, and other natural disasters, may have a long-term impact on our business, financial condition and results of operation. While 
we seek to mitigate our business risks associated with climate events, we recognize that there are inherent climate-related risks regardless 
of where we conduct our businesses. For example, a catastrophic natural disaster could negatively impact any of our office locations 
and the locations of our clients. Accordingly, a natural disaster has the potential to disrupt our and our clients’ businesses and may cause 
us to experience work stoppages, project delays, financial losses and additional costs to resume operations, including increased insurance 
costs or loss of cover, legal liability and reputational losses. 

There is a rapidly evolving awareness and focus from stakeholders with respect to environmental, social and governance practices, 
which could affect our business.  

Stakeholder  expectations  with  respect  to  environmental,  social  and  governance  matters  have  been  rapidly  evolving  and 
increasing. We risk damage to our reputation if we do not act responsibly in key areas including diversity and inclusion, environmental 
stewardship, support for local communities and corporate governance. A failure to adequately meet stakeholders’ expectations may 
result in loss of business, and an inability to attract and retain customers and talented personnel, which could have a negative impact on 
our business, results of operations and financial condition, and potentially on the price of our common stock and cost of capital. 

Risks Related to Acquisitions and Divestitures 

We may be unable to successfully execute or effectively integrate acquisitions and divestitures may not occur as planned. 

We regularly review our portfolio of businesses and pursue growth through acquisitions and seek to divest non-core businesses. 
We may not be able to complete transactions on favorable terms, on a timely basis, or at all, and during the integration of any acquisition, 
we may discover regulatory and compliance issues. In addition, our results of operations and cash flows may be adversely impacted by 
(i) the failure of acquired businesses to meet or exceed expected returns; (ii) the failure to integrate acquired businesses on schedule 
and/or to achieve expected synergies; (iii) the inability to dispose of non-core assets and businesses on satisfactory terms and conditions; 
(iv) diversion of attention and increased burdens on our employees; and (v) the discovery of unanticipated liabilities or other problems 
in acquired businesses for which we lack contractual protections, insurance or indemnities, or with regard to divested businesses, claims 
by purchasers to whom we have provided contractual indemnification. Additional difficulties we may encounter as part of the integration 
process include the following: 

• 

the consequences of a change in tax treatment and the possibility that the full benefits anticipated from the acquisition or 
disposition will not be realized; 

24 

 
• 

• 

• 

• 

• 

• 

• 

• 

any delay in the integration or disposition of management teams, strategies, operations, products and services; 

differences  in  business  backgrounds,  corporate  cultures  and  management  philosophies  that  may  delay  successful 
integration; 

the ability to retain key employees; 

the ability to create and enforce uniform standards, controls, procedures, policies and information systems; 

the challenge of restructuring complex systems, technology, networks and other assets in a seamless manner that minimizes 
any adverse impact on customers, suppliers, employees and other constituencies; 

potential unknown liabilities and unforeseen increased expenses or delays associated with the acquisition, including costs 
to integrate beyond current estimates; 

the ability to deduct or claim tax attributes or benefits such as operating losses, business or foreign tax credits; and 

the disruption of, or the loss of momentum in, each company’s ongoing businesses or inconsistencies in standards, controls, 
procedures and policies. 

Any of these factors could adversely affect our ability to maintain relationships with customers, suppliers, employees and other 

constituencies or could reduce our earnings or otherwise adversely affect our business and financial results. 

Our  plans  to  divest  businesses  are  subject  to  various  risks  and  uncertainties  and  may  not  be  completed  in  accordance  with  the 
expected plans or anticipated time frame, or at all, and will involve significant time and expense, which could disrupt or adversely 
affect our business. 

Divesting businesses involve risks and uncertainties, such as the difficulty separating assets related to such businesses from the 
businesses we retain, employee distraction, the need to obtain regulatory approvals and other third-party consents, which potentially 
disrupts customer and vendor relationships, and the fact that we may be subject to additional tax obligations or loss of tax benefits. 
Because of these challenges, as well as market conditions or other factors, anticipated divestitures may take longer or be costlier or 
generate fewer benefits than expected and may not be completed at all. If we are unable to complete divestitures or to successfully 
transition divested businesses, our business and financial results could be negatively impacted. After we dispose of a business, we may 
retain  exposure  on  financial  or performance  guarantees  and  other  contractual,  employment,  pension  and  severance  obligations,  and 
potential liabilities that may arise under law because of the disposition or the subsequent failure of an acquirer. Our results of operations, 
cash flows, working capital, effective tax rate, and financing requirements may be subject to increased volatility and our ability to fund 
capital expenditures, investments and service debt may be diminished. In addition, any purchase price adjustments could be unfavorable 
and other future proceeds owed to us as part of these transactions could be lower than we expect. As a result, performance by the divested 
businesses or other conditions outside of our control could have a material adverse effect on our results of operations. In addition, the 
divestiture of any business could negatively impact our profitability because of losses that may result from such a sale, the loss of sales 
and operating income, or a decrease in cash flows. 

Other Risks 

An impairment charge of goodwill could have a material adverse impact on our financial condition and results of operations. 

Because we have grown in part through acquisitions, goodwill and intangible assets-net represent a substantial portion of our 
assets, and were $3.4 billion and $17.8 million, respectively as of September 30, 2023. Under generally accepted accounting principles 
in the United States, we are required to test goodwill carried in our consolidated balance sheets for possible impairment on an annual 
basis based upon a fair value approach and whenever events occur that indicate impairment could exist. These events or circumstances 
could include a significant change in the business climate, including a significant sustained decline in a reporting unit’s market value, 
legal factors, operating performance indicators, competition, sale or disposition of a significant portion of our business, a significant 
sustained decline in our market capitalization and other factors. 

25 

 
In addition, if we experience a decrease in our stock price and market capitalization over a sustained period, we would have to 
record an impairment charge in the future. The amount of any impairment could be significant and could have a material adverse impact 
on our financial condition and results of operations for the period in which the charge is taken. 

We may be required to contribute additional cash to meet our significant underfunded benefit obligations associated with pension 
benefit plans we manage or multiemployer pension plans in which we participate. 

We have defined benefit pension plans for employees in the United States, United Kingdom, Canada, Australia, and Ireland. 
At September 30, 2023, our defined benefit pension plans had an aggregate deficit (the excess of projected benefit obligations over the 
fair value of plan assets) of approximately $165.3 million. In the future, our pension deficits may increase or decrease depending on 
changes  in  the  levels  of  interest  rates,  pension  plan  performance  and  other  factors  that  may  require  us  to  make  additional  cash 
contributions to our pension plans and recognize further increases in our net pension cost to satisfy our funding requirements. If we are 
forced or elect to make up all or a portion of the deficit for unfunded benefit plans, our results of operations could be materially and 
adversely affected. 

A multiemployer pension plan is typically established under a collective bargaining agreement with a union to cover the union-
represented  workers  of  various  unrelated  companies.  Our  collective  bargaining  agreements  with  unions  require  us  to  contribute  to 
various multiemployer pension plans; however, we do not control or manage these plans. For the year ended September 30, 2023, we 
contributed  $3.0  million  to  multiemployer  pension  plans.  Under  the  Employee  Retirement  Income  Security  Act,  an  employer  who 
contributes to a multiemployer pension plan, absent an applicable exemption, may also be liable, upon termination or withdrawal from 
the plan, for its proportionate share of the multiemployer pension plan’s unfunded vested benefit. If we terminate or withdraw from a 
multiemployer plan, absent an applicable exemption (such as for some plans in the building and construction industry), we could be 
required to contribute a significant amount of cash to fund the multiemployer plan’s unfunded vested benefit, which could materially 
and adversely affect our financial results; however, since we do not control the multiemployer plans, we are unable to estimate any 
potential contributions that could be required. 

We  may  experience  disproportionately  high  levels  of  collection  risk  and  nonpayment  if  clients  in  specific  geographic  areas  or 
industries are adversely affected by factors particular to their geographic area or industry. 

Our clients include public and private entities that have been, and may continue to be, negatively impacted by the changing 
landscape in the global economy. While no one client accounted for over 10% of our revenue for fiscal 2023, we face collection risk as 
a normal part of our business where we perform services and subsequently bill our clients for such services, or when we make equity 
investments  in  majority  or  minority  controlled  large-scale  client  projects  and  other  long-term  capital  projects  before  the  project 
completes  operational  status  or  completes  its  project  financing.  In  the  event  that  we  have  concentrated  credit  risk  from  clients  in  a 
specific geographic area or industry, continuing negative trends or a worsening in the financial condition of that specific geographic 
area or industry could make us susceptible to disproportionately high levels of default by those clients. Such defaults could materially 
adversely impact our revenues, results of operations or accounts receivable. 

Our services expose us to significant risks of liability and our insurance policies may not provide adequate coverage. 

Our services involve significant risks of professional and other liabilities that may substantially exceed the fees that we derive 
from such services. In addition, we sometimes contractually assume liability to clients on projects under indemnification or guarantee 
agreements. We cannot predict the magnitude of potential liabilities from the operation of our business. In addition, in the ordinary 
course  of  our  business,  we  frequently  make  professional  judgments  and  recommendations  about  environmental  and  engineering 
conditions of project sites for our clients. We may be deemed to be responsible for these professional judgments and recommendations 
if they are later determined to be inaccurate. Any unfavorable legal ruling against us could result in substantial monetary damages or 
even criminal violations. 

Our professional liability policies cover only claims made during the term of the policy. Additionally, our insurance policies 
may not protect us against potential liability due to various exclusions in the policies and self-insured retention amounts. Partially or 
completely uninsured claims, if successful and of significant magnitude, could have a material adverse effect on our business. 

26 

 
Unavailability  or  cancellation  of  third-party  insurance  coverage  would  increase  our  overall  risk  exposure  as  well  as  disrupt  the 
management of our business operations. 

We maintain insurance coverage from third-party insurers as part of our overall risk management strategy and because some 
of our contracts require us to maintain specific insurance coverage limits. If any of our third-party insurers fail, suddenly cancel our 
coverage or otherwise are unable to provide us with adequate insurance coverage, then our overall risk exposure and our operational 
expenses would increase and the management of our business operations would be disrupted. In addition, there can be no assurance that 
any of our existing insurance coverage will be renewable upon the expiration of the coverage period or that future coverage will be 
affordable at the required limits. 

If we do not have adequate indemnification for our services related to nuclear materials, it could adversely affect our business and 
financial condition. 

We provide services to the nuclear energy industry in the ongoing maintenance and modification, as well as the decontamination 
and decommissioning, of nuclear energy plants. Indemnification provisions under the Price-Anderson Act available to nuclear energy 
plant operators and contractors do not apply to all liabilities that we might incur while performing services as a radioactive materials 
cleanup contractor for the nuclear energy industry. If the Price-Anderson Act’s indemnification protection does not apply to our services 
or if our exposure occurs outside the U.S., our business and financial condition could be adversely affected either by our client’s refusal 
to retain us, by our inability to obtain commercially adequate insurance and indemnification, or by potentially significant monetary 
damages we may incur. 

Our  backlog  of  uncompleted  projects  under  contract  is  subject  to  unexpected  adjustments  and  cancellations  and,  thus  may  not 
accurately reflect future revenue and profits. 

At  September 30,  2023,  backlog  was  approximately  $41.2  billion.  We  reported  transaction  price  allocated  to  remaining 
unsatisfied  performance  obligations  (RUPO)  of  $21.9  billion,  as  described  in  Note  4,  Revenue  Recognition,  in  the  notes  to  our 
consolidated financial statements. The most significant differences between our backlog and RUPO are backlog contains revenue we 
expect  to  record  in  the  future  where  we  have  been  awarded  the  work,  but  the  contractual  agreement  has  not  yet  been  signed, 
unconsolidated joint venture backlog where we expect to realize income through equity earnings rather than revenue, and revenue related 
to  service  contracts  that  extend  beyond  the  termination  provisions  of  those  contracts,  where  guidance  for  the  calculation  of  RUPO 
requires us to assume the contract will be terminated at its earliest convenience. Accordingly, RUPO is $19.3 billion lower than backlog. 
We cannot guarantee that future revenue will be realized from either category of backlog or, if realized, will result in profits. Many 
projects may remain in our backlog for an extended period of time because of the size or long-term nature of the contract. In addition, 
from time to time, projects are delayed, scaled back or canceled. These types of backlog reductions adversely affect the revenue and 
profits that we ultimately receive from contracts reflected in our backlog.  

From time to time, we submit claims to clients for work we performed beyond the initial scope of some of our contracts. If these 
clients do not approve these claims, our results of operations could be adversely impacted. 

We typically have pending claims submitted under some of our contracts for payment of work performed beyond the initial 
contractual requirements for which we have already recorded revenue. In general, we cannot guarantee that such claims will be approved 
in whole, in part, or at all. Often, these claims can be the subject of lengthy arbitration or litigation proceedings, and it is difficult to 
accurately predict when these claims will be fully resolved. When these types of events occur and unresolved claims are pending, we 
have  used  working  capital  in  projects  to  cover  cost  overruns  pending  the  resolution  of  the  relevant  claims.  If  these  claims  are  not 
approved, our revenue may be reduced in future periods. 

27 

 
In conducting our business, we depend on other contractors, subcontractors and equipment and material providers. If these parties 
fail to satisfy their obligations to us or other parties or if we are unable to maintain these relationships, our revenue, profitability 
and growth prospects could be adversely affected. 

We depend on contractors, subcontractors and equipment and material providers in conducting our business. There is a risk 
that we may have disputes with our subcontractors arising from, among other things, the quality and timeliness of work performed by 
the subcontractor, customer concerns about the subcontractor, or our failure to extend existing task orders or issue new task orders under 
a subcontract. Also, to the extent that we cannot acquire equipment and materials at reasonable costs, or if the amount we are required 
to pay exceeds our estimates, our ability to complete a project in a timely fashion or at a profit may be impaired. In addition, if any of 
our subcontractors fail to deliver on a timely basis the agreed-upon supplies and/or perform the agreed-upon services, our ability to 
fulfill our obligations as a prime contractor may be jeopardized; we could be held responsible for such failures and/or we may be required 
to purchase the supplies or services from another source at a higher price. This may reduce the profit to be realized or result in a loss on 
a project for which the supplies or services are needed. 

We also rely on relationships with other contractors when we act as their subcontractor or joint venture partner. Our future 
revenue and growth prospects could be adversely affected if other contractors eliminate or reduce their subcontracts or joint venture 
relationships with us, or if a government agency terminates or reduces these other contractors’ programs, does not award them new 
contracts or refuses to pay under a contract. In addition, due to “pay when paid” provisions that are common in subcontracts in many 
countries, including the U.S., we could experience delays in receiving payment if the prime contractor experiences payment delays. 

If clients use our reports or other work product without appropriate disclaimers or in a misleading or incomplete manner, or if our 
reports  or  other  work  product  are  not  in  compliance  with  professional  standards  and  other  regulations,  our  business  could  be 
adversely affected. 

The reports and other work product we produce for clients sometimes include projections, forecasts and other forward-looking 
statements. Such information by its nature is subject to numerous risks and uncertainties, any of which could cause the information 
produced by us to ultimately prove inaccurate. While we include appropriate disclaimers in the reports that we prepare for our clients, 
once we produce such written work product, we do not always have the ability to control the manner in which our clients use such 
information.  As  a  result,  if  our  clients  reproduce  such  information  to  solicit  funds  from  investors  for  projects  without  appropriate 
disclaimers and the information proves to be incorrect, or if our clients reproduce such information for potential investors in a misleading 
or  incomplete  manner,  our  clients  or  such  investors  may  threaten  to  or  file  suit  against  us  for,  among  other  things,  securities  law 
violations. If we were found to be liable for any claims related to our client work product, our business could be adversely affected. 

In  addition,  our  reports  and  other  work  product  may  need  to  comply  with  professional  standards,  licensing  requirements, 
securities regulations and other laws and rules governing the performance of professional services in the jurisdiction where the services 
are performed. We could be liable to third parties who use or rely upon our reports and other work product even if we are not contractually 
bound to those third parties. These events could in turn result in monetary damages and penalties. 

Failure  to  adequately  protect,  maintain,  or  enforce  our  rights  in  our  intellectual  property  may  adversely  limit  our  competitive 
position. 

Our success depends, in part, upon our ability to protect our intellectual property. We rely on a combination of intellectual 
property policies and other contractual arrangements to protect much of our intellectual property where we do not believe that trademark, 
patent or copyright protection is appropriate or obtainable. Trade secrets are generally difficult to protect. Although our employees are 
subject  to  confidentiality  obligations,  this  protection  may  be  inadequate  to  deter  or  prevent  misappropriation  of  our  confidential 
information  and/or  the  infringement  of  our  patents  and  copyrights.  Further,  we  may  be  unable  to  detect  unauthorized  use  of  our 
intellectual property or otherwise take appropriate steps to enforce our rights. Failure to adequately protect, maintain, or enforce our 
intellectual property rights may adversely limit our competitive position. 

28 

 
Our revenue and growth prospects may be harmed if we or our employees are unable to obtain government granted eligibility or 
other qualifications we and they need to perform services for our customers. 

A  number  of  government  programs  require  contractors  to  have  government  granted  eligibility,  such  as  security  clearance 
credentials. Depending on the project, eligibility can be difficult and time-consuming to obtain. If we or our employees are unable to 
obtain or retain the necessary eligibility, we may not be able to win new business, and our existing customers could terminate their 
contracts with us or decide  not  to  renew  them.  To  the  extent we  cannot obtain or  maintain  the  required  security  clearances  for our 
employees working on a particular contract, we may not derive the revenue or profit anticipated from such contract. 

Negotiations with labor unions and possible work actions could divert management attention and disrupt operations. In addition, 
new collective bargaining agreements or amendments to agreements could increase our labor costs and operating expenses. 

We  regularly  negotiate  with  labor  unions  and  enter  into  collective  bargaining  agreements.  The  outcome  of  any  future 
negotiations relating to union representation or collective bargaining agreements may not be favorable to us. We may reach agreements 
in collective bargaining that increase our operating expenses and lower our net income as a result of higher wages or benefit expenses. 
In addition, negotiations with unions could divert management attention and disrupt operations, which may adversely affect our results 
of operations. If we are unable to negotiate acceptable collective bargaining agreements, we may have to address the threat of union-
initiated work actions, including strikes. Depending on the nature of the threat or the type and duration of any work action, these actions 
could disrupt our operations and adversely affect our operating results. 

Our charter documents contain provisions that may delay, defer or prevent a change of control. 

Provisions of our certificate of incorporation and bylaws could make it more difficult for a third party to acquire control of us, 

even if the change in control would be beneficial to stockholders. These provisions include the following: 

• 

• 

• 

ability of our Board of Directors to authorize the issuance of preferred stock in series without stockholder approval; 

vesting of exclusive authority in our Board of Directors to determine the size of the board and to fill vacancies; and 

advance notice requirements for stockholder proposals and nominations for election to our Board of Directors. 

We cannot guarantee the timing, amount or payment of dividends. 

Although our Board of Directors has adopted a dividend policy under which we intend to pay a regular quarterly cash dividend, 
the  timing  and  amount of  any subsequently  declared dividend  (or  any  special dividend)  is subject  to  the discretion of  the  Board  of 
Directors  and  will  be  based  on  a  variety  of  factors,  including  cash  flows,  earnings  and  financial  borrowing  availability  and  other 
restrictions under our outstanding indebtedness. We are not required to declare dividends and we are restricted under our outstanding 
indebtedness and could be restricted under future financing or other arrangements. Our Board of Directors may modify or terminate our 
dividend policy. Accordingly, we cannot provide any assurances that we will pay quarterly or special dividends or the amount or timing 
thereof. Any reduction or elimination of our dividend policy or dividend payments could have a negative effect on the price of our 
common stock. 

Changes in tax laws could increase our worldwide tax rate and materially affect our results of operations. 

We are subject to tax laws in the U.S. and numerous foreign jurisdictions. The U.S. and many international legislative and 
regulatory  bodies  continually  propose  and  enact  legislation  that  could  significantly  impact  how  U.S.  multinational  corporations  are 
taxed. 

The  Organization  for  Economic  Co-operation  and  Development  (OECD),  a  global  coalition  of  member  countries,  has 
developed a two-pillar framework to reform international taxation. The proposal aims to ensure that multinationals pay a minimum rate 
of tax on their foreign profits through the introduction of a global minimum tax among other provisions. As this framework is subject 

29 

 
to further negotiation and implementation by each member country, the timing and ultimate impact of any such changes on our tax 
obligations are uncertain. 

Due to the large scale of our U.S. and international business activities, many of these proposed changes, if enacted into law, 

could have an adverse impact on our worldwide effective tax rate, income tax expense and cash flows. 

ITEM 1B.  UNRESOLVED STAFF COMMENTS 

None. 

ITEM 2.  PROPERTIES 

Our corporate offices are located in approximately 9,000 square feet of space at 13355 Noel Road, Dallas, Texas. Our other 
offices, including smaller administrative or project offices, consist of an aggregate of approximately 6.4 million square feet worldwide. 
Virtually all of our offices are leased. See Note 11 in the notes to our consolidated financial statements for information regarding our 
lease obligations. We may add additional facilities from time to time in the future as the need arises. 

ITEM 3.  LEGAL PROCEEDINGS 

As a government contractor, we are subject to various laws and regulations that are more restrictive than those applicable to 
non-government contractors. Intense government scrutiny of contractors’ compliance with those laws and regulations through audits 
and investigations is inherent in government contracting and, from time to time, we receive inquiries, subpoenas, and similar demands 
related to our ongoing business with government entities. Violations can result in civil or criminal liability as well as suspension or 
debarment from eligibility for awards of new government contracts or option renewals. 

We are involved in various investigations, claims and lawsuits in the normal conduct of our business. We are not always aware 
if we or our affiliates are under investigation or the status of such matters. Although the outcome of our legal proceedings cannot be 
predicted with certainty and no assurances can be provided, in the opinion of our management, based upon current information and 
discussions  with  counsel,  with  the  exception  of  the  matters  noted  in  Note  18,  Commitments  and  Contingencies,  to  the  financial 
statements contained in this report to the extent stated therein, none of the investigations, claims and lawsuits in which we are involved 
is expected to have a material adverse effect on our consolidated financial position, results of operations, cash flows or our ability to 
conduct business. See Note 18, Commitments and Contingencies, to the financial statements contained in this report for a discussion of 
certain matters to which we are a party. The information set forth in such note is incorporated by reference into this Item 3. From time 
to time, we establish reserves for litigation when we consider it probable that a loss will occur.

Performance Measurement Comparison(1) 

The following chart compares the cumulative total stockholder return of AECOM stock (ACM) with the cumulative total return 
of the S&P MidCap 400, and the S&P Composite 1500 Construction & Engineering, from September 28, 2018 to September 29, 2023.  

We believe the S&P 400 MidCap is an appropriate independent broad market index, since it measures the performance of 
similar mid-sized companies in numerous sectors. In addition, we believe the S&P Composite 1500 Construction & Engineering index 
is an appropriate third party published industry index since it measures the performance of engineering and construction companies.

SEC. Accordingly, actual results could differ materially from those contemplated by any forward-looking statement. 

All  subsequent  written  and  oral  forward-looking  statements  concerning  the  Company  or  other  matters  attributable  to  the 
Company  or  any  person  acting  on  its  behalf  are  expressly  qualified  in  their  entirety  by  the  cautionary  statements  above.  You  are 
cautioned not to place undue reliance on these forward-looking statements, which speak only to the date they are made. The Company 
is under no obligation (and expressly disclaims any such obligation) to update or revise any forward-looking statement that may be

Risk Factors” in this Annual Report for a discussion of the factors, risks and uncertainties that could affect our future results. 

Our fiscal year consists of 52 or 53 weeks, ending on the Friday closest to September 30. For clarity of presentation, we present 
all periods as if the year ended on September 30. We refer to the fiscal year ended September 30, 2022 as “fiscal 2022” and the fiscal 
year ended September 30, 2023 as “fiscal 2023.” Fiscal years 2023, 2022, and 2021 each contained 52, 52, and 52 weeks, respectively, 
and ended on September 29, September 30, and October 1, respectively. 

In this section, we discuss the results of our operations for the year ended September 30, 2023 compared to the year ended 
September 30, 2022. For a discussion on the year ended September 30, 2022 compared to the year ended September 30, 2021, please 
refer to Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual 
Report on Form 10-K for the year ended September 30, 2022. 

Overview 

We  are  a  leading  global  provider  of  professional  infrastructure  consulting  services  for  governments,  businesses  and 
organizations throughout the world. We provide advisory, planning, consulting, architectural and engineering design, construction and 

33 

 
program management services, and investment and development services to public and private clients worldwide in major end markets 
such as transportation, facilities, water, environmental, and energy. 

Our business focuses primarily on providing fee-based knowledge-based services. We primarily derive income from our ability 
to generate revenue and collect cash from our clients through the billing of our employees’ time spent on client projects and our ability 
to manage our costs. AECOM Capital primarily derives its income from real estate development sales and management fees. 

We  report  our  continuing  business  through  three  segments,  each  of  which  is  described  in  further  detail  below:  Americas, 
International, and AECOM Capital (ACAP). Such segments are organized by the differing specialized needs of the respective clients, 
and how we manage the business. We have aggregated various operating segments into our reportable segments based on their similar 
characteristics, including similar long-term financial performance, the nature of services provided, internal processes for delivering those 
services, and types of customers. 

•  Americas: Planning, consulting, architectural and engineering design, construction management and program management 
services  to  public  and  private  clients  in  the  United  States,  Canada,  and  Latin  America  in  major  end  markets  such  as 
transportation, water, government, facilities, environmental, and energy. 

• 

International: Planning, consulting, architectural and engineering design services and program management to public and 
private clients in Europe, the Middle East, India, Africa and the Asia-Australia-Pacific regions in major end markets such 
as transportation, water, government, facilities, environmental, and energy. 

•  AECOM Capital (ACAP): Primarily invests in and develops real estate projects. 

Our revenue is dependent on our ability to attract and retain qualified and productive employees, identify business opportunities, 
allocate  our  labor  resources  and  capital  to  profitable  and  high  growth  markets,  secure  new  contracts,  and  renew  existing  client 
agreements.  Demand  for  our  services  may  be  vulnerable  to  sudden  economic  downturns  and  reductions  in  government  and  private 
industry  spending,  which  may  result  in  clients  delaying,  curtailing  or  canceling  proposed  and  existing  projects.  Moreover,  as  a 
professional services company, maintaining the high quality of the work generated by our employees is integral to our revenue generation 
and profitability. Given the global nature of our business, our revenue is exposed to currency rate fluctuations that could change from 
period to period and year to year. 

Our costs consist primarily of the compensation we pay to our employees, including salaries, fringe benefits, the costs of hiring 

subcontractors, other project-related expenses and sales, general and administrative costs. 

In September 2021, the Board approved an increase in our stock repurchase authorization to $1.0 billion. At September 30, 
2023, we have approximately $220 million remaining of the Board’s repurchase authorization. We intend to deploy future available 
cash towards dividends and stock repurchases consistent with our return driven capital allocation policy. 

We have exited substantially all of our self-perform at-risk construction businesses and divested our remaining non-core oil 
and  gas  businesses  in  January 2022.  As  part  of  our  ongoing  plan  to  improve  profitability  and  maintain  a  reduced  risk  profile,  we 
continuously evaluate our geographic exposure. In March 2022, we substantially completed our exit of all business operations in Russia 
consistent with our announcement on March 7, 2022.  

In  fiscal  year  2023,  we  initiated  a  process  to  explore  strategic  options  for  the  AECOM  Capital  business.  This  process  is 
consistent with our focus on our professional services business. AECOM Capital will continue to support AECOM’s existing investment 
vehicles and investments in a manner consistent with their current obligations. We initiated a project-by-project review of the existing 
investment portfolio, including an analysis of the incremental cash requirements that might be required to carry the investments on our 
balance  sheet  if  current  market  conditions  persist. We  determined  that  the  incremental investments  to  these  assets  did not  meet  the 
objectives of our capital allocation policy. We reflected this change in strategy and the expected acceleration of these investment exits 
as an impairment charge of $307.0 million in the third quarter of fiscal 2023. This impairment did not relate to investments in respect 
of which affiliates of AECOM Capital provide advisory services or manage third party capital. 

We expect to incur restructuring costs of approximately $50 million to $70 million in fiscal 2024, primarily related to ongoing 
actions  that  are  expected  to  deliver  continued  margin  improvement  and  efficiencies.  Our  estimated  restructuring  costs  include  the 
ongoing optimization of our office real estate portfolio and exit of certain countries in Southeast Asia, subject to applicable laws, as part 
of our ongoing plan to evaluate our geographic exposure and reduce our risk profile.

We  generate  revenue  primarily  by  providing  planning,  consulting,  architectural  and  engineering  design,  construction  and 
program management services to public and private clients around the world. Our revenue consists of both services provided by our 
employees  and  pass-through  revenues  from  subcontractors  and  other  direct  costs.  We  generally  recognize  revenue  over  time  as 
performance  obligations  are  satisfied  and  control  over  promised  goods  or  services  are  transferred  to  our  customers.  We  generally 
measure progress to completion using an input measure of total costs incurred divided by total costs expected to be incurred. 

Cost of Revenue 

Cost  of  revenue  reflects  the  cost  of  our  own  personnel  (including  fringe  benefits  and  overhead  expense)  and  fees  from 

subcontractors and other direct costs associated with revenue. 

Amortization Expense of Acquired Intangible Assets 

Included in our cost of revenue is amortization of acquired intangible assets. We have ascribed value to identifiable intangible 
assets other than goodwill in our purchase price allocations for companies we have acquired. These assets include, but are not limited 
to, backlog and customer relationships. To the extent we ascribe value to identifiable intangible assets that have finite lives, we amortize 
those values over the estimated useful lives of the assets. Such amortization expense, although non-cash in the period expensed, directly 
impacts our results of operations. 

Equity in Earnings of Joint Ventures 

Equity in earnings of joint ventures includes our portion of fees charged by our unconsolidated joint ventures to clients for 
services  performed  by  us  and  other  joint  venture  partners  along  with  earnings  we  receive  from  our  return  on  investments  in 
unconsolidated joint ventures. 

General and Administrative Expenses 

General and administrative expenses include corporate expenses, including personnel, occupancy, and administrative expenses.

Restructuring Expenses 

Restructuring expenses are comprised of personnel and other costs, real estate costs, and costs associated with the exit of our 

Russia-related businesses primarily related to actions that are expected to deliver continued margin improvements and efficiencies. 

Geographic Information 

For geographic financial information, please refer to Note 4 and Note 19 in the notes to our consolidated financial statements 

found elsewhere in the Form 10-K. 

Critical Accounting Estimates 

Our  accounting  policies,  including  those  described  below,  often  require  management  to  make  significant  estimates  and 
assumptions using information available at the time the estimates are made. Such estimates and assumptions significantly affect various 
reported  amounts  of  assets,  liabilities,  revenue  and  expenses.  If  future  experience  differs  significantly  from  these  estimates  and 
assumptions, our results of operations and financial condition could be affected. Our most critical accounting policies and estimates are 
described below. We have not materially changed our estimation methodology during the period presented. 

Revenue Recognition 

Our accounting policies establish principles for recognizing revenue upon the transfer of control of promised goods or services 
to customers. We generally recognize revenues over time as performance obligations are satisfied. We generally measure our progress 
to completion using an input measure of total costs incurred divided by total costs expected to be incurred. In the course of providing 
these services, we routinely subcontract for services and incur other direct cost on behalf of our clients. These costs are passed through 
to clients and, in accordance with accounting rules, are included in our revenue and cost of revenue. 

Revenue recognition and profit is dependent upon a number of factors, including the accuracy of a variety of estimates made 
at the balance sheet date, such as engineering progress, material quantities, the achievement of milestones, penalty provisions, labor 
productivity and cost estimates. Additionally, we are required to make estimates for the amount of consideration to be received, including 
bonuses, awards, incentive fees, claims, unpriced change orders, penalties and liquidated damages. Variable consideration is included 
in the estimate of transaction price only to the extent that a significant reversal would not be probable. We continuously monitor factors 
that may affect the quality of our estimates, and material changes in estimates are disclosed accordingly. 

Claims Recognition 

Claims are amounts in excess of the agreed contract price (or amounts not included in the original contract price) that we seek 
to collect from customers or others for delays, errors in specifications and designs, contract terminations, change orders in dispute or 
unapproved contracts as to both scope and price or other causes of unanticipated additional costs. Judgment is required to estimate the 
amount, if any, of revenue to be recognized on claims. We record contract revenue related to claims only if it is probable that the claim 
will result in additional contract revenue and only to the extent that a significant reversal would not be probable. The amounts recorded, 
if material, are disclosed in the notes to the financial statements. Costs attributable to claims are treated as costs of contract performance 
as incurred. 

Government Contract Matters 

Our federal government and certain state and local agency contracts are subject to, among other regulations, regulations issued 
under the Federal Acquisition Regulations (FAR). These regulations can limit the recovery of certain specified indirect costs on contracts 
and subject us to ongoing multiple audits by government agencies such as the Defense Contract Audit Agency (DCAA). In addition, 
most of our federal and state and local contracts are subject to termination at the discretion of the client. 

Audits by the DCAA and other agencies consist of reviews of our overhead rates, operating systems and cost proposals to 
ensure that we account for such costs in accordance with the Cost Accounting Standards of the FAR (CAS). If the DCAA determines 
we have not accounted for such costs consistent with CAS, the DCAA may disallow these costs. There can be no assurance that audits 
by the DCAA or other governmental agencies will not result in material cost disallowances in the future. 

36 

 
Allowance for Doubtful Accounts and Expected Credit Losses 

We record accounts receivable net of an allowance for doubtful accounts. This allowance for doubtful accounts is estimated 
based on management’s evaluation of the contracts involved and the financial condition of our clients. The factors we consider in our 
contract evaluations include, but are not limited to: 

•  Client type—federal or state and local government or commercial client; 

•  Historical contract performance; 

•  Historical collection and delinquency trends; 

•  Client credit worthiness; and 

•  General economic conditions. 

Contract Assets and Contract Liabilities 

Contract assets represent the contract revenue recognized but not yet billed pursuant to contract terms. 

Contract liabilities represent the billings to date, as allowed under the terms of a contract, but not yet recognized as contract 

revenue using our revenue recognition policy. 

Investments in Unconsolidated Joint Ventures 

We have noncontrolling interests in joint ventures accounted for under the equity method. Fees received for and the associated 
costs of services performed by us and billed to joint ventures with respect to work done by us for third-party customers are recorded as 
our revenues and costs in the period in which such services are rendered. In certain joint ventures, a fee is added to the respective billings 
from both us and the other joint venture partners on the amounts billed to the third-party customers. These fees result in earnings to the 
joint venture and are split with each of the joint venture partners and paid to the joint venture partners upon collection from the third-party 
customer. We record our allocated share of these fees as equity in earnings of joint ventures. 

Additionally, our ACAP segment primarily invests in real estate projects.   

Income Taxes 

We provide for income taxes in accordance with principles contained in ASC Topic 740, Income Taxes. Under these principles, 
we recognize the amount of income tax payable or refundable for the current year and deferred tax assets and liabilities for the future 
tax consequences of events that have been recognized in our financial statements or tax returns. 

Deferred  tax  assets  and  liabilities  are  measured  using  enacted  tax  rates  in  effect  for  the  year  in  which  those  temporary 
differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized 
in earnings in the period when the new rate is enacted. Deferred tax assets are evaluated for future realization and reduced by a valuation 
allowance if it is more likely than not that a portion will not be realized. 

We measure and recognize the amount of tax benefit that should be recorded for financial statement purposes for uncertain tax 
positions taken or expected to be taken in a tax return. With respect to uncertain tax positions, we evaluate the recognized tax benefits 
for  recognition,  measurement,  derecognition,  classification,  interest  and  penalties,  interim  period  accounting  and  disclosure 
requirements.  Judgment  is  required  in  assessing  the  future  tax  consequences  of  events  that  have  been  recognized  in  our  financial 
statements or tax returns. 

Valuation Allowance.  Deferred income taxes are provided on the liability method whereby deferred tax assets and liabilities 
are established for the difference between the financial reporting and income tax basis of assets and liabilities, as well as for tax attributes 
such as operating loss and tax credit carryforwards. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws 
and tax rates on the date of enactment of such changes to laws and tax rates. 

37 

 
Deferred tax assets are reduced by a valuation allowance when, in our opinion, it is more likely than not that some portion or 
all of the deferred tax assets may not be realized. The evaluation of the recoverability of the deferred tax asset requires the Company to 
weigh all positive and negative evidence to reach a conclusion that it is more likely than not that all or some portion of the deferred tax 
assets will not be realized. The weight given to the evidence is commensurate with the extent to which it can be objectively verified. 
Whether a deferred tax asset may be realized requires considerable judgment by us. In considering the need for a valuation allowance, 
we consider a number of factors including the nature, frequency, and severity of cumulative financial reporting losses in recent years, 
the future reversal of existing temporary differences, predictability of future taxable income exclusive of reversing temporary differences 
of  the  character  necessary  to  realize  the  asset,  relevant  carryforward  periods,  taxable  income  in  carry-back  years  if  carry-back  is 
permitted under tax law, and prudent and feasible tax planning strategies that would be implemented, if necessary, to protect against the 
loss of the deferred tax asset that would otherwise expire. Whether a deferred tax asset will ultimately be realized is also dependent on 
varying factors, including, but not limited to, changes in tax laws and audits by tax jurisdictions in which we operate. 

If future changes in judgment regarding the realizability of our deferred tax assets lead us to determine that it is more likely 
than not that we will not realize all or part of our deferred tax asset in the future, we will record an additional valuation allowance. 
Conversely, if a valuation allowance exists and we determine that the ultimate realizability of all or part of the net deferred tax asset is 
more likely than not to be realized, then the amount of the valuation allowance will be reduced. This adjustment will increase or decrease 
income tax expense in the period of such determination. 

Undistributed Non-U.S. Earnings.  The results of our operations outside of the United States are consolidated for financial 
reporting; however, earnings from investments in non-U.S. operations are included in domestic U.S. taxable income only when actually 
or constructively received. No deferred taxes have been provided on the undistributed gross book-tax basis differences of our non-U.S. 
operations  of  approximately  $1.3  billion  because  we  have  the  ability  to  and  intend  to  permanently  reinvest  these  basis  differences 
overseas. If we were to repatriate these basis differences, additional taxes could be due at that time. 

We continually explore initiatives to better align our tax and legal entity structure with the footprint of our non-U.S. operations 
and  we  recognize  the  tax  impact  of  these  initiatives,  including  changes  in  assessment  of  its  uncertain  tax  positions,  indefinite 
reinvestment exception assertions and realizability of deferred tax assets, earliest in the period when management believes all necessary 
internal and external approvals associated with such initiatives have been obtained, or when the initiatives are materially complete. 

Goodwill and Acquired Intangible Assets 

Goodwill  represents  the  excess  of  amounts  paid  over  the  fair  value  of  net  assets  acquired  from  an  acquisition.  In  order  to 
determine  the  amount  of  goodwill  resulting  from  an  acquisition,  we  perform  an  assessment  to  determine  the  value  of  the  acquired 
company’s tangible and identifiable intangible assets and liabilities. In our assessment, we determine whether identifiable intangible 
assets exist, which typically include backlog and customer relationships. 

We test goodwill for impairment annually for each reporting unit in the beginning of the fourth quarter of the fiscal year and 
between  annual  tests,  if  events  occur  or  circumstances  change  which  suggest  that  goodwill  should  be  evaluated.  Such  events  or 
circumstances include significant changes in legal factors and business climate, recent losses at a reporting unit, and industry trends, 
among other factors. A reporting unit is defined as an operating segment or one level below an operating segment. Our impairment tests 
are performed at the operating segment level as they represent our reporting units. 

Goodwill  is  evaluated  for  impairment  either  by  assessing  qualitative  factors  or  by  performing  a  quantitative  assessment. 
Qualitative factors, such as overall financial performance, industry or market considerations, or other relevant events, are assessed to 
determine if it is more likely than not that the fair value of the reporting units is less than their carrying amounts. During a quantitative 
impairment test, we estimate the fair value of the reporting unit using income and market approaches, and compare that amount to the 
carrying value of that reporting unit. In the event the fair value of the reporting unit is determined to be less than the carrying value, 
goodwill is impaired, and an impairment loss is recognized equal to the excess, limited to the total amount of goodwill allocated to the 
reporting unit. 

The impairment evaluation process includes, among other things, making assumptions about variables such as revenue growth 

rates, profitability, discount rates, and industry market multiples, which are subject to a high degree of judgment. 

There are inherent uncertainties related to each of the above listed assumptions, and our judgment in applying them. Changes 
in  the  assumptions  used  in  our  goodwill  and  intangible  assets  could  result  in  impairment  charges  that  could  be  material  to  our 
consolidated financial statements in any given period. We have not materially changed our estimation methodology during the periods 
presented.

Pension Benefit Obligations 

A number of assumptions are necessary to determine our pension liabilities and net periodic costs. These liabilities and net 
periodic costs are sensitive to changes in those assumptions. The assumptions include discount rates, long-term rates of return on plan 
assets and inflation levels limited to the United Kingdom and are generally determined based on the current economic environment in 
each host country at the end of each respective annual reporting period. We evaluate the funded status of each of our retirement plans 
using  these  current  assumptions  and  determine  the  appropriate  funding  level  considering  applicable  regulatory  requirements,  tax 
deductibility, reporting considerations and other factors. Based upon current assumptions, we expect to contribute $22.2 million to our 
international plans in fiscal 2024. Our required minimum contributions for our U.S. qualified plans are not significant. In addition, we 
may make additional discretionary contributions. We currently expect to contribute $12.9 million to our U.S. plans (including benefit 
payments to nonqualified plans and postretirement medical plans) in fiscal 2024. If the discount rate was reduced by 25 basis points, 
plan liabilities would increase by approximately $26.6 million. If the discount rate and return on plan assets were reduced by 25 basis 
points, plan expense would increase by approximately $0.3 million and increase by approximately $2.7 million, respectively. If inflation 
increased by 25 basis points, plan liabilities in the United Kingdom would increase by approximately $17.1 million and plan expense 
would increase by approximately $2.0 million. 

At each measurement date, all assumptions are reviewed and adjusted as appropriate. With respect to establishing the return on 
assets  assumption,  we  consider  the  long-term  capital  market  expectations  for  each  asset  class  held  as  an  investment  by  the  various 
pension plans. In addition to expected returns for each asset class, we take into account standard deviation of returns and correlation 
between asset classes. This is necessary in order to generate a distribution of possible returns which reflects diversification of assets. 
Based on this information, a distribution of possible returns is generated based on the plan’s target asset allocation. 

Capital market expectations for determining the long-term rate of return on assets are based on forward-looking assumptions 
which reflect a 20-year view of the capital markets. In establishing those capital market assumptions and expectations, we rely on the 
assistance of our actuaries and our investment consultants. We and the plan trustees review whether changes to the various plans’ target 
asset allocations are appropriate. A change in the plans’ target asset allocations would likely result in a change in the expected return on 
asset assumptions. In assessing a plan’s asset allocation strategy, we and the plan trustees consider factors such as the structure of the 
plan’s liabilities, the plan’s funded status, and the impact of the asset allocation to the volatility of the plan’s funded status, so that the 
overall risk level resulting from our defined benefit plans is appropriate within our risk management strategy. 

Between September 30, 2022 and September 30, 2023, the aggregate worldwide pension deficit decreased from $204.4 million 
to $165.3 million due to increased discount rates. If the various plans do not experience future investment gains to reduce this shortfall, 
the deficit will be reduced by additional contributions. 

Accrued Professional Liability Costs 

We carry professional liability insurance policies or self-insure for our initial layer of professional liability claims under our 
professional liability insurance policies and for a deductible for each claim even after exceeding the self-insured retention. We accrue 
for our portion of the estimated ultimate liability for the estimated potential incurred losses. We establish our estimate of loss for each 
potential claim in consultation with legal counsel handling the specific matters and based on historic trends taking into account recent 
events. We also use an outside actuarial firm to assist us in estimating our future claims exposure. It is possible that our estimate of loss 
may be revised based on the actual or revised estimate of liability of the claims.

Revenue 

Our revenue for the year ended September 30, 2023 increased $1,230.3 million, or 9.4%, to $14,378.5 million as compared to 

$13,148.2 million for the corresponding period last year. 

In the course of providing our services, we routinely subcontract for services and incur other direct costs on behalf of our 
clients. These costs are passed through to clients and, in accordance with industry practice and GAAP, are included in our revenue and 
cost of revenue. Because these pass-through revenues can change significantly from project to project and period to period, changes in 
revenue  may  not  be  indicative  of  business  trends.  Pass-through  revenues  for  the  years  ended  September 30,  2023  and  2022  were 
$7.7 billion and $6.8 billion, respectively. Pass-through revenue as a percentage of total revenue was 53% and 52% during the year 
ended September 30, 2023 and 2022, respectively. 

Gross Profit 

Our gross profit for the year ended September 30, 2023 increased $97.5 million, or 11.5%, to $945.5 million as compared to 
$848.0 million for the corresponding period last year. For the year ended September 30, 2023, gross profit, as a percentage of revenue, 
increased to 6.6% from 6.4% in the year ended September 30, 2022. 

Gross profit changes were due to the reasons noted in Americas and International reportable segments below.

Equity in (Losses) Earnings of Joint Ventures 

Our equity in losses of joint ventures for the year ended September 30, 2023 was $279.4 million as compared to equity in 

earnings of $53.6 million in the corresponding period last year. 

The decrease in earnings of joint ventures for the year ended September 30, 2023 compared to the same period in the prior year 
was  primarily  due  to  impairment  losses  recorded  in  our  AECOM  Capital  segment  during  the  third  quarter  of  fiscal  2023.  These 
impairments were primarily as a result of a project-by-project review of the existing investment portfolio, the expected acceleration of 
exits from certain investments caused by a change in strategy, and volatility in the commercial real estate market caused by higher 
interest rates and lack of liquidity. 

General and Administrative Expenses 

Our  general  and  administrative  expenses  for  the  year  ended  September 30,  2023  increased  $6.3  million,  or  4.3%,  to 
$153.6 million as compared to $147.3 million for the corresponding period last year. For the years ended September 30, 2023 and 2022, 
general and administrative expenses as a percentage of revenue remained unchanged at 1.1%. 

Restructuring Costs 

Restructuring expenses are comprised of personnel costs, real estate costs, and costs associated with business exits. During 
fiscal year ended September 30, 2023, we incurred total restructuring expenses of $188.4 million primarily related to actions taken to 
align our real estate portfolio with our employee flexibility initiatives and costs incurred in preparation for the exit of certain countries 
in Southeast Asia. During fiscal year ended September 30, 2022, we incurred restructuring expenses of $107.5 million, primarily related 
to costs associated with exit of Russia-related businesses and management actions to deliver margin improvement and efficiencies that 
result in a more agile organization. 

Interest Income 

Our interest income for the year ended September 30, 2023 increased to $40.3 million from $8.2 million for the corresponding 

period last year. 

The increase in interest income for the year ended September 30, 2023 was primarily due to an increase in interest rates on our 

interest-bearing assets. 

Interest Expense 

Our  interest  expense  for  the  year  ended  September 30,  2023  was  $159.3  million  as  compared  to  $110.2  million  for  the 

corresponding period last year. 

The increase in interest expense for the year ended September 30, 2023 was primarily due to an increase in interest rates on the 

variable component of our debt. 

42 

 
Income Tax Expense 

Our income tax expense for the year ended September 30, 2023 was $56.1 million compared to $136.1 million for the year 
ended September 30, 2022. The decrease in tax expense for the current period compared to the corresponding period last year was due 
primarily  to  a  tax  benefit  of  $65.0  million  related  to  the  AECOM  Capital  impairment  charge,  including  an  increase  in  valuation 
allowances of $21.0 million for the portion of the charge that is not expected to be realized, and a net tax benefit recorded in fiscal 2022 
related to changes in valuation allowances providing a tax benefit of $21.9 million and foreign uncertain tax provisions generating a tax 
expense of $16.1 million. 

During the first quarter of fiscal 2022, valuation allowances in the amount of $21.9 million primarily related to net operating 
losses in certain foreign entities were released due to sufficient positive evidence. The positive evidence included a realignment of our 
global transfer pricing methodology which resulted in forecasting the utilization of the net operating losses within the foreseeable future. 

We are currently under tax audit in several jurisdictions including the U.S. and believe the outcomes which are reasonably 
possible within the next twelve months, including lapses in statutes of limitations, could result in future adjustments, but will not result 
in a material change in the liability for uncertain tax positions. 

We regularly integrate and consolidate our business operations and legal entity structure, and such internal initiatives could 

impact the assessment of uncertain tax positions, indefinite reinvestment assertions and the realizability of deferred tax assets. 

Net Loss From Discontinued Operations 

During the first quarter of fiscal 2020, management approved a plan to dispose of via sale our self-perform at-risk construction 
businesses.  As  a  result  of  these  strategic  actions,  the  self-perform  at-risk  construction  businesses  were  classified  as  discontinued 
operations. That classification was applied retrospectively for all periods presented. 

Net loss from discontinued operations was $57.2 million for the year ended September 30, 2023 and net loss was $79.9 million 
for the year ended September 30, 2022, a decrease of $22.7 million. The decrease in net loss from discontinued operations for the year 
ended September 30, 2023 was primarily due to losses related to revisions of estimates for our working capital obligations to be paid 
and contingent consideration receivable related to the civil infrastructure business recorded in the first half of fiscal 2022 that did not 
recur to the same extent in fiscal 2023. 

Net Income Attributable to AECOM 

The  factors  described  above  resulted  in  the  net  income  attributable  to  AECOM  of  $55.3  million  for  the  year  ended 
September 30, 2023, as compared to the net income attributable to AECOM of $310.6 million for the year ended September 30, 2022.

Revenue  for  our  Americas  segment  for  the  year  ended  September 30,  2023  increased  $1,036.4  million,  or  10.4%,  to 

$10,975.7 million as compared to $9,939.3 million for the corresponding period last year. 

The  increase  in  revenue  for  the  year  ended  September 30,  2023  was  primarily  driven  by  increased  project  activity  in  the 

Americas design business including growth in the Water, Transportation, and Environment markets. 

Gross Profit 

Gross  profit  for  our  Americas  segment  for  the  year  ended  September 30,  2023  increased  $59.8  million,  or  9.3%,  to 
$699.7 million as compared to $639.9 million for the corresponding period last year. Gross profit, as a percentage of revenue, remained 
unchanged at 6.4% for the years ended September 30, 2023 and 2022. 

The  increase  in  gross  profit  for  the  year  ended  September 30,  2023  was  primarily  due  to  revenue  growth  and  execution 

efficiency. In addition, underlying revenue, excluding pass-through revenues, increased.

Revenue 

Revenue  for  our  International  segment  for  the  year  ended  September 30,  2023  increased  $195.4  million,  or  6.1%,  to 

$3,402.1 million as compared to $3,206.7 million for the corresponding period last year. 

The increase in revenue for the year ended September 30, 2023 was primarily due to increased growth in the United Kingdom, 
Middle East and Australia compared to the prior year, which more than offset the impact of the stronger U.S. dollar as compared to the 
functional currencies of our foreign operations. Growth was led by the Transportation, Facilities, and Water markets. 

Gross Profit 

Gross  profit  for  our  International  segment  for  the  year  ended  September 30,  2023  increased  $39.2  million,  or  19.0%,  to 
$245.1 million as compared to $205.9 million for the corresponding period last year. As a percentage of revenue, gross profit increased 
to 7.2% of revenue for the year ended September 30, 2023 from 6.4% in the corresponding period last year.

The increase in gross profit and gross profit as a percentage of revenue for the year ended September 30, 2023 was primarily 
due to an increase in revenue and reduced costs resulting from country exits, ongoing investments in enterprise capability centers, shared 
service centers, and delivery efficiency.

Equity in earnings of joint ventures for the year ended September 30, 2023 decreased $328.3 million, or 1345.5%, to a loss of 
$303.9 million compared to earnings of $24.4 million for the corresponding period in the prior year. The decrease was primarily due to 
impairment losses recognized in the third quarter of fiscal 2023. 

Liquidity and Capital Resources 

Cash Flows 

Our principal sources of liquidity are cash flows from operations, borrowings under our credit facilities, and access to financial 
markets. Our principal uses of cash are operating expenses, capital expenditures, working capital requirements, acquisitions, repurchases 
of common stock, dividend payments, and refinancing or repayment of debt. We believe our anticipated sources of liquidity including 
operating cash flows, existing cash and cash equivalents, borrowing capacity under our revolving credit facility and our ability to issue 
debt or equity, if required, will be sufficient to meet our projected cash requirements for at least the next twelve months. We expect to 
spend approximately $110 million in restructuring costs in fiscal 2024 associated with ongoing restructuring actions that are expected 
to deliver continued margin improvement and efficiencies. 

Generally, we do not provide for U.S. taxes or foreign withholding taxes on gross book-tax basis differences in our non-U.S. 
subsidiaries  because  such  basis  differences  are  able  to  and  intended  to  be  reinvested  indefinitely.  At  September 30,  2023,  we  have 
determined that we will continue to indefinitely reinvest the earnings of some foreign subsidiaries and, therefore, we will continue to 
account for these undistributed earnings based on our existing accounting under ASC 740 and not accrue additional tax. Determination 
of  the  amount  of  any  unrecognized  deferred  income  tax  liability  on  this  temporary  difference  is  not  practicable  because  of  the 
complexities  of  the  hypothetical  calculation.  Based  on  the  available  sources  of  cash  flows  discussed  above,  we  anticipate  we  will 
continue to have the ability to permanently reinvest these remaining amounts. 

At September 30, 2023, cash and cash equivalents, including cash and cash equivalents included in current assets held for sale, 
were $1,262.2 million, an increase of $85.4 million, or 7.3%, from $1,176.8 million at September 30, 2022. The increase in cash and 
cash  equivalents  was  primarily  attributable  to  a  decrease  of  $93.7  million  of  cash  used  to  repurchase  common  stock,  of  which 
$67.9 million was related to a decrease in repurchases under the existing Board repurchase authorization. 

Net  cash  provided  by  operating  activities  was  $696.0  million  for  the  year  ended  September 30,  2023  as  compared  to 
$713.6 million for the year ended September 30, 2022. The change was primarily attributable to a decrease in cash provided by working 
capital of approximately $84.2 million, offset by an increase in adjustments for non-cash items of approximately $301.1 million and a 
decrease in net income of approximately $234.6 million. The sale of trade receivables to financial institutions included in operating cash 
flows increased $50.0 million during the year ended September 30, 2023 compared to the year ended September 30, 2022. We expect 
to continue to sell trade receivables in the future as long as the terms continue to remain favorable to us.

Net cash used in investing activities was $138.2 million for the year ended September 30, 2023, as compared to $175.0 million 
for the year ended September 30, 2022. The decrease in cash used in investing activities was primarily due to cash outflows for sale of 
discontinued operations of $42.3 million in fiscal year 2022 that did not repeat in the current year.   

Net cash used in financing activities was $472.9 million for the year ended September 30, 2023, as compared to $588.3 million 
for the year ended September 30, 2022. The decrease from the prior year was primarily attributable to decreased stock repurchases under 
the Stock Repurchase Program. Total borrowings under our Credit Agreement may vary during the period as we regularly draw and 
repay amounts to fund working capital. 

Working Capital 

Working capital, or current assets less current liabilities, decreased $99.4 million, or 23.7%, to $319.2 million at September 30, 
2023 from $418.6 million at September 30, 2022. Net accounts receivable and contract assets, net of contract liabilities, increased to 
$2,880.8 million at September 30, 2023 from $2,671.9 million at September 30, 2022.  

Days  Sales  Outstanding  (DSO),  which  includes  net  accounts  receivable  and  contract  assets,  net  of  contract  liabilities,  was 

65 days at September 30, 2023 compared to 68 days at September 30, 2022. 

In Note 4, Revenue Recognition, in the notes to our consolidated financial statements, a comparative analysis of the various 
components of accounts receivable is provided. Except for claims, substantially all contract assets are expected to be billed and collected 
within twelve months. 

Contract assets related to claims are recorded only if it is probable that the claim will result in additional contract revenue and 
only to the extent that a significant reversal would not be probable. In such cases, revenue is recorded only to the extent that contract 
costs relating to the claim have been incurred. Award fees in contract assets are accrued only when there is sufficient information to 
assess contract performance. On contracts that represent higher than normal risk or technical difficulty, award fees are generally deferred 
until an award fee letter is received. 

Because our revenue depends to a great extent on billable labor hours, most of our charges are invoiced following the end of 
the month in which the hours were worked, the majority usually within 15 days. Other direct costs are normally billed along with labor 
hours. However, as opposed to salary costs, which are generally paid on either a bi-weekly or monthly basis, other direct costs are 
generally not paid until payment is received (in some cases in the form of advances) from the customers.

Credit Agreement 

On February 8, 2021, we entered into the 2021 Refinancing Amendment to the Credit Agreement (as amended, modified or 
otherwise  supplemented,  the  “Credit  Agreement”),  pursuant  to  which  we  amended  and  restated  our  Syndicated  Credit  Facility 
Agreement,  dated  as  of  October 17,  2014  (as  amended  prior  to  February 8,  2021,  the  “Original  Credit  Agreement”),  between  the 
Company, as borrower, Bank of America, N.A., as administrative agent, and other parties thereto. At the time of amendment, the Credit 
Agreement consisted of a $1,150,000,000 revolving credit facility (the “Revolving Credit Facility”) and a $246,968,737.50 term loan A 
facility (the “Term A Facility,” together with the Revolving Credit Facility, the “Credit Facilities”), each of which mature on February 8, 
2026. The outstanding loans under the Term A Facility were borrowed in U.S. dollars. Loans under the Revolving Credit Facility may 
be  borrowed,  and  letters  of  credit  thereunder  may  be  issued,  in  U.S.  dollars  or  in  certain  foreign  currencies.  The  proceeds  of  the 
Revolving Credit Facility may be used from time to time for ongoing working capital and for other general corporate purposes. The 
proceeds of the Revolving Credit Facility and the Term A Loan facility borrowed on February 8, 2021 were used to refinance the existing 
revolving credit facility and the existing term loan facility under the Original Credit Agreement and to pay related fees and expenses. 
The Credit Agreement permits us to designate certain of our subsidiaries as additional co-borrowers from time to time. Currently, there 
are no co-borrowers under the Credit Facilities.  

On April 13, 2021, we entered into Amendment No. 10 to the Credit Agreement, pursuant to which the lenders thereunder 
provided a secured term B credit facility (the “Term B Facility”) to the Company in an aggregate principal amount of $700,000,000. 
The Term B Facility matures on April 13, 2028. The proceeds of the Term B Facility were used to fund the purchase price, fees and 
expenses in connection with our cash tender offer to purchase up to $700,000,000 aggregate purchase price (not including any accrued 
and unpaid interest) of our outstanding 5.875% Senior Notes due 2024. 

On June 25, 2021, we entered into Amendment No. 11 to the Credit Agreement, pursuant to which lenders thereunder have 
provided us with an additional $215,000,000 in aggregate principal amount under the Term A Facility. We used the net proceeds from 
the increase in the Term A Facility (together with cash on hand), to (i) redeem all of our remaining 5.875% Senior Notes due 2024 and 
(ii) pay fees and expenses related to such redemption. 

On May 23, 2023, the Company entered into Amendment No. 12 to the Credit Agreement, pursuant to which LIBOR as a 
benchmark rate of interest was replaced by, in the case of US Dollar-denominated loans, a secured overnight financing rate subject to a 
spread adjustment, and, in the case of loans denominated in other currencies, other customary successor rates, subject in certain cases 
to a spread adjustment. On May 23, 2023, the Company entered into Amendment No. 13 to the Credit Agreement, pursuant to which 
the spread adjustments with respect to the Revolving Credit Facility and the Term A Facility was amended.  

The applicable interest rate for loans under the Term B Facility is calculated at a per annum rate equal to, at our option, (a) the 

Term SOFR (as defined in the Credit Agreement) plus 1.75% or (b) the Base Rate (as defined in the Credit Agreement) plus 0.75%. 

The applicable interest rate for U.S. Dollar-denominated loans under the Revolving Credit Facility and the Term A Facility is 
calculated at a per annum rate equal to, at our option, (a) the Term SOFR (as defined in the Credit Agreement) plus an applicable margin 
(the “SOFR Applicable Margin”), which is currently at 1.2250% or (b) the Base Rate (as defined in the Credit Agreement) plus an 
applicable margin (the “Base Rate Applicable Margin,” and together with the SOFR Applicable Margin, the “Applicable Margins”), 
which is currently at 0.2250%. The applicable interest rate for loans under the Revolving Credit Facility denominated in other currencies 
is calculated at a per annum rate equal to a customary floating reference rate for such currency specified in the Credit Agreement plus 
the SOFR Applicable Margin. The Credit Agreement includes certain environmental, social and governance (ESG) metrics relating to 
our CO2 emissions and the percentage of employees who identify as women (each, a “Sustainability Metric”). The Applicable Margins 

47 

 
 
 
 
 
 
        
  
  
 
 
  
 
for the Term A Facility and the Revolving Credit Facility and the commitment fees for the Revolving Credit Facility will be adjusted 
on an annual basis based on our achievement of preset thresholds for each Sustainability Metric. 

Some  of  our  material  subsidiaries  (the  “Guarantors”)  have  guaranteed  the  obligations  of  the  borrowers  under  the  Credit 
Agreement, subject to certain exceptions. The borrowers’ obligations under the Credit Agreement are secured by a lien on substantially 
all of our assets and the Guarantors’ assets, subject to certain exceptions.  

The Credit Agreement contains customary negative covenants that include, among other things, limitations on our and certain 
of our subsidiaries’ ability, subject to certain exceptions, to incur liens and debt, make investments, dispositions, and restricted payments, 
change the nature of our business, consummate mergers, consolidations and the sale of all or substantially all of our respective assets, 
taken as a whole, and transact with affiliates. We are also required to maintain a consolidated interest coverage ratio of at least 3.00 to 
1.00 and a consolidated leverage ratio of less than or equal to 4.00 to 1.00 (subject to certain adjustments in connection with permitted 
acquisitions), tested on a quarterly basis (the “Financial Covenants”). The Financial Covenants do not apply to the Term B Facility. Our 
consolidated  leverage  ratio  was  2.00  to  1.00  at  September 30,  2023.  As  of  September 30,  2023,  we  were  in  compliance  with  the 
covenants of the Credit Agreement. 

The Credit Agreement contains customary affirmative covenants, including, among other things, compliance with applicable 
law, preservation of existence, maintenance of properties and of insurance, and keeping proper books and records. The Credit Agreement 
contains customary events of default, including, among other things, nonpayment of principal, interest or fees, cross-defaults to other 
debt,  inaccuracies  of  representations  and  warranties,  failure  to  perform  covenants,  events  of  bankruptcy  and  insolvency,  change  of 
control and unsatisfied judgments, subject in certain cases to notice and cure periods and other exceptions. 

At September 30, 2023 and September 30, 2022, letters of credit totaled $4.4 million and $4.4 million, respectively, under our 
Revolving  Credit  Facility.  As  of  September 30,  2023  and  September 30,  2022,  we  had  $1,145.6  million  and  $1,145.6  million, 
respectively, available under our revolving credit facility. 

2027 Senior Notes 

On  February 21,  2017,  we  completed  a  private  placement  offering  of  $1,000,000,000  aggregate  principal  amount  of  our 
unsecured 5.125% Senior Notes due 2027 (the “2027 Senior Notes”). On June 30, 2017, we completed an exchange offer to exchange 
the unregistered 2027 Senior Notes for registered notes, as well as related guarantees. 

As of September 30, 2023, the estimated fair value of the 2027 Senior Notes was approximately $939.9 million. The fair value 
of the 2027 Senior Notes as of September 30, 2023 was derived by taking the mid-point of the trading prices from an observable market 
input (Level 2) in the secondary bond market and multiplying it by the outstanding balance of the 2027 Senior Notes. Interest is payable 
on the 2027 Senior Notes at a rate of 5.125% per annum. Interest on the 2027 Senior Notes is payable semi-annually on March 15 and 
September 15 of each year, commencing on September 15, 2017. The 2027 Senior Notes will mature on March 15, 2027. 

At any time and from time to time prior to December 15, 2026, we may redeem all or part of the 2027 Senior Notes, at a 
redemption price equal to 100% of their principal amount, plus a “make whole” premium as of the redemption date, and accrued and 
unpaid  interest  to  the  redemption  date.  On  or  after  December 15,  2026,  we  may  redeem  all  or  part  of  the  2027  Senior  Notes  at  a 
redemption price equal to 100% of their principal amount, plus accrued and unpaid interest on the redemption date. 

The indenture pursuant to which the 2027 Senior Notes were issued contains customary events of default, including, among 
other things, payment default, exchange default, failure to provide notices thereunder and provisions related to bankruptcy events. The 
indenture also contains customary negative covenants. 

We were in compliance with the covenants relating to the 2027 Senior Notes as of September 30, 2023. 

Other Debt and Other Items 

Other debt consists primarily of obligations under capital leases and loans and unsecured credit facilities. The unsecured credit 
facilities are primarily used for standby letters of credit issued in connection with general and professional liability insurance programs 
and  for  contract  performance  guarantees.  At  September 30,  2023  and  2022,  these  outstanding  standby  letters  of  credit  totaled 
$878.9 million and $640.3 million, respectively. As of September 30, 2023, we had $416.7 million available under these unsecured 
credit facilities.

Effective Interest Rate 

Our  average  effective  interest  rate  on  our  total  debt,  including  the  effects  of  the  interest  rate  swap  and  interest  rate  cap 

agreements during the years ended September 30, 2023, 2022 and 2021 was 5.3%, 3.8% and 4.4%, respectively. 

Interest expense in the consolidated statements of operations included amortization of deferred debt issuance costs for the years 

ended September 30, 2023, 2022 and 2021 of $4.9 million, $4.9 million and $10.2 million, respectively. 

Other Commitments 

We  enter  into various  joint venture  arrangements  to provide  architectural,  engineering,  program  management,  construction 
management and operations and maintenance services. The ownership percentage of these joint ventures is typically representative of 
the work to be performed or the amount of risk assumed by each joint venture partner. Some of these joint ventures are considered 
variable interest entities. We have consolidated all joint ventures for which we have control. For all others, our portion of the earnings 
is  recorded  in  equity  in  earnings  of  joint  ventures.  See  Note  6,  Joint  Ventures  and  Variable  Interest  Entities,  in  the  notes  to  our 
consolidated financial statements. 

Other  than  normal  property  and  equipment  additions  and  replacements,  expenditures  to  further  the  implementation  of  our 
various  information  technology  systems,  commitments  under  our  incentive  compensation  programs,  amounts  we  may  expend  to 
repurchase stock under our stock repurchase program and acquisitions from time to time and disposition costs, we currently do not have 
any significant capital expenditures or outlays planned except as described below. However, if we acquire additional businesses in the 
future or if we embark on other capital-intensive initiatives, additional working capital may be required. 

Under  our  secured  revolving  credit  facility  and  other  facilities  discussed  in  Other  Debt  and  Other  Items  above,  as  of 
September 30, 2023, there was approximately $883.3 million including both continuing and discontinued operations, outstanding under 
standby  letters  of  credit  primarily  issued  in  connection  with  general  and  professional  liability  insurance  programs  and  for  contract 
performance guarantees. For those projects for which we have issued a performance guarantee, if the project subsequently fails to meet 
guaranteed performance standards, we may either incur significant additional costs or be held responsible for the costs incurred by the 
client to achieve the required performance standards. 

We recognized on our balance sheet the funded status of our pension benefit plans, measured as the difference between the fair 
value of plan assets and the projected benefit obligation. At September 30, 2023, our defined benefit pension plans had an aggregate 
deficit (the excess of projected benefit obligations over the fair value of plan assets) of approximately $165.3 million. The total amounts 
of employer contributions paid for the year ended September 30, 2023 were $8.2 million for U.S. plans and $24.8 million for non-U.S. 
plans. Funding requirements for each plan are determined based on the local laws of the country where such plan resides. In some 
countries,  the  funding  requirements  are  mandatory  while  in  other  countries,  they  are  discretionary.  There  is  a  required  minimum 
contribution for one of our domestic plans; however, we may make additional discretionary contributions. In the future, such pension 
funding may increase or decrease depending on changes in the levels of interest rates, pension plan performance and other factors. In 
addition, we have collective bargaining agreements with unions that require us to contribute to various third-party multiemployer plans 
that we do not control or manage. For the year ended September 30, 2023, we contributed $3.0 million to multiemployer pension plans. 

Condensed Combined Financial Information 

The 2027 Senior Notes are fully and unconditionally guaranteed on a joint and several basis by some of AECOM’s directly 
and indirectly 100% owned subsidiaries (the Subsidiary Guarantors). Accordingly, AECOM became subject to the requirements of Rule

Commitments and Contingencies 

We  record  amounts  representing  our  probable  estimated  liabilities  relating  to  claims,  guarantees,  litigation,  audits  and 
investigations. We rely in part on qualified actuaries to assist us in determining the level of reserves to establish for insurance-related 
claims that are known and have been asserted against us, and for insurance-related claims that are believed to have been incurred based 
on actuarial analysis, but have not yet been reported to our claims administrators as of the respective balance sheet dates. We include 
any  adjustments  to  such  insurance  reserves  in  our  consolidated  results  of  operations.  Our  reasonably  possible  loss  disclosures  are 
presented on a gross basis prior to the consideration of insurance recoveries. We do not record gain contingencies until they are realized. 
In the ordinary course of business, we may not be aware that we or our affiliates are under investigation and may not be aware of whether 
or not a known investigation has been concluded.

In the ordinary course of business, we may enter into various arrangements providing financial or performance assurance to 
clients, lenders, or partners. Such arrangements include standby letters of credit, surety bonds, and corporate guarantees to support the 
creditworthiness  or  the  project  execution  commitments  of  our  affiliates,  partnerships  and  joint  ventures.  Performance  arrangements 
typically have various expiration dates ranging from the completion of the project contract and extending beyond contract completion 
in some circumstances such as for warranties. We may also guarantee that a project, when complete, will achieve specified performance 
standards. If the project subsequently fails to meet guaranteed performance standards, we may incur additional costs, pay liquidated 
damages or be held responsible for the costs incurred by the client to achieve the required performance standards. The potential payment 
amount of an outstanding performance arrangement is typically the remaining cost of work to be performed by or on behalf of third 
parties. Generally, under joint venture arrangements, if a partner is financially unable to complete its share of the contract, the other 
partner(s) may be required to complete those activities. 

At September 30, 2023, we were contingently liable in the amount of approximately $883.3 million in issued standby letters of 

credit and $4.6 billion in issued surety bonds primarily to support project execution. 

In the ordinary course of business, we enter into various agreements providing financial or performance assurances to clients 
on behalf of certain unconsolidated partnerships, joint ventures and other jointly executed contracts. These agreements are entered into 
primarily to support the project execution commitments of these entities. 

Our  investment  adviser  jointly  manages  and  sponsors  the  AECOM-Canyon  Equity  Fund,  L.P.  (the  “Fund”),  in  which  we 
indirectly hold an equity interest and have an ongoing capital commitment to fund investments. At September 30, 2023, we have capital 
commitments of $8.3 million to the Fund over the next 5 years. 

In  addition,  in  connection  with  the  investment  activities  of  AECOM  Capital,  we  provide  guarantees  of  certain  contractual 
obligations, including guarantees for completion of projects, repayment of debt, environmental indemnity obligations and other lender 
required guarantees. 

Department of Energy Deactivation, Demolition, and Removal Project 

A  former  affiliate  of  the  Company,  Amentum  Environment &  Energy,  Inc.,  f/k/a  AECOM  Energy  and  Construction,  Inc. 
(“Former Affiliate”), executed a cost-reimbursable task order with the Department of Energy (DOE) in 2007 to provide deactivation, 
demolition and removal services at a New York State project site that, during 2010, experienced contamination and performance issues. 
In February 2011, the Former Affiliate and the DOE executed a Task Order Modification that changed some cost-reimbursable contract 
provisions to at-risk. The Task Order Modification, including subsequent amendments, required the DOE to pay all project costs up to 
$106 million, required the Former Affiliate and the DOE to equally share in all project costs incurred from $106 million to $146 million, 
and required the Former Affiliate to pay all project costs exceeding $146 million. 

Due to unanticipated requirements and permitting delays by federal and state agencies, as well as delays and related ground 
stabilization activities caused by Hurricane Irene in 2011, the Former Affiliate was required to perform work outside the scope of the 
Task Order Modification. In December 2014, the Former Affiliate submitted an initial set of claims against the DOE pursuant to the 
Contracts Disputes Acts seeking recovery of $103 million, including additional fees on changed work scope (the “2014 Claims”). On 
December 6,  2019,  the  Former  Affiliate  submitted  a  second  set  of  claims  against  the  DOE  seeking  recovery  of  an  additional 
$60.4 million, including additional project costs and delays outside the scope of the contract as a result of differing site and ground 
conditions (the “2019 Claims”). The Former Affiliate also submitted three alternative breach of contract claims to the 2014 and 2019 
Claims that may entitle the Former Affiliate to recovery of $148.5 million to $329.4 million. On December 30, 2019, the DOE denied 
the Former Affiliate’s 2014 Claims. On September 25, 2020, the DOE denied the Former Affiliate’s 2019 Claims. The Company filed 
an appeal of these decisions on December 20, 2020 in the Court of Federal Claims. Deconstruction, decommissioning and site restoration 
activities are complete. 

51 

 
On January 31, 2020, the Company completed the sale of its Management Services business, including the Former Affiliate 
who worked on the DOE project, to Maverick Purchaser Sub LLC (MS Purchaser), an affiliate of American Securities LLC and Lindsay 
Goldberg LLC. The Company and the MS Purchaser agreed that all future DOE project claim recoveries and costs will be split 10% to 
the MS Purchaser and 90% to the Company with the Company retaining control of all future strategic legal decisions. 

The Company intends to vigorously pursue all claimed amounts but can provide no certainty that the Company will recover 
2014  Claims  and 2019  Claims  submitted against  the DOE,  or any  additional  incurred  claims  or  costs,  which  could  have  a material 
adverse effect on the Company’s results of operations. 

Refinery Turnaround Project 

A Former Affiliate of the Company entered into an agreement to perform turnaround maintenance services during a planned 
shutdown at a refinery in Montana in December 2017. The turnaround project was completed in February 2019. Due to circumstances 
outside  of  the  Company’s  Former  Affiliate’s  control,  including  client  directed  changes  and  delays  and  the  refinery’s  condition,  the 
Company’s Former Affiliate performed additional work outside of the original contract over $90 million and is entitled to payment from 
the refinery owner of approximately $144 million. In March 2019, the refinery owner sent a letter to the Company’s Former Affiliate 
alleging it incurred approximately $79 million in damages due to the Company’s Former Affiliate’s project performance. In April 2019, 
the Company’s Former Affiliate filed and perfected a $132 million construction lien against the refinery for unpaid labor and materials 
costs. In August 2019, following a subcontractor complaint filed in the Thirteen Judicial District Court of Montana asserting claims 
against the refinery owner and the Company’s Former Affiliate, the refinery owner crossclaimed against the Company’s Former Affiliate 
and the subcontractor. In October 2019, following the subcontractor’s dismissal of its claims, the Company’s Former Affiliate removed 
the matter to federal court and cross claimed against the refinery owner. In December 2019, the refinery owner claimed $93.0 million 
in damages and offsets against the Company’s Former Affiliate. 

On January 31, 2020, the Company completed the sale of its Management Services business, including the Former Affiliate, 
to  the  MS  Purchaser;  however,  the  Refinery  Turnaround  Project,  including  related  claims  and  liabilities,  has  been  retained  by  the 
Company. 

The Company intends to vigorously prosecute and defend this matter; however, the Company cannot provide assurance that 
the Company will be successful in these efforts. The resolution of this matter and any potential range of loss cannot be reasonably 
determined or estimated at this time, primarily because the matter raises complex legal issues that Company is continuing to assess.

New Accounting Pronouncements and Changes in Accounting 

In December 2019, the Financial Accounting Standards Board (FASB) issued new accounting guidance which simplifies the 
accounting for income taxes. The guidance amends certain exceptions to the general principles of Accounting Standards Codification 
(ASC) 740, Income Taxes, and simplifies several areas such as accounting for a franchise tax or similar tax that is partially based on 
income. We adopted the new guidance starting on October 1, 2021. The adoption of the new guidance did not have a significant impact 
on our consolidated financial statements. 

In October 2021, the FASB issued final guidance to companies that apply ASC 606, Revenue from Contracts with Customers, 
to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination. The 

52 

 
 
 
 
 
 
 
     
   
   
     
 
  
  
  
 
new guidance creates an exception to the general requirement to measure acquired assets and liabilities at fair value on the acquisition 
date.  Under  this  exception,  an  acquirer  applies  ASC  606  to  recognize  and  measure  contract  assets  and  contract  liabilities  on  the 
acquisition date. We adopted the new guidance starting on October 1, 2022 on a prospective basis and the revised guidance will be 
applied to any business combinations the Company undertakes. 

Off-Balance Sheet Arrangements 

We  enter  into various  joint venture  arrangements  to provide  architectural,  engineering,  program  management,  construction 
management and operations and maintenance services. The ownership percentage of these joint ventures is typically representative of 
the work to be performed or the amount of risk assumed by each joint venture partner. Some of these joint ventures are considered 
variable interest entities. We have consolidated all joint ventures for which we have control. For all others, our portion of the earnings 
are recorded in equity in earnings of joint ventures. See Note 6 in the notes to our consolidated financial statements. We do not believe 
that we have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial 
condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources 
that would be material to investors. 

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

Financial Market Risks 

We are exposed to market risk, primarily related to foreign currency exchange rates and interest rate exposure of our debt 
obligations that bear interest based on floating rates. We actively monitor these exposures. Our objective is to reduce, where we deem 
appropriate to do so, fluctuations in earnings and cash flows associated with changes in foreign exchange rates and interest rates. In 
order to accomplish this objective, we sometimes enter into derivative financial instruments, such as forward contracts and interest rate 
hedge contracts. It is our policy and practice to use derivative financial instruments only to the extent necessary to manage our exposures. 
We do not use derivative financial instruments for trading purposes. 

Foreign Exchange Rates 

We are exposed to foreign currency exchange rate risk resulting from our operations outside of the U.S. We use foreign currency 
forward contracts from time to time to mitigate foreign currency risk. We limit exposure to foreign currency fluctuations in most of our 
contracts through provisions that require client payments in currencies corresponding to the currency in which costs are incurred. As a 
result of this natural hedge, we generally do not need to hedge foreign currency cash flows for contract work performed. The functional 
currency of our significant foreign operations is the respective local currency. 

Interest Rates 

Our Credit Agreement and other debt obligations are subject to variable rate interest which could be adversely affected by an 
increase in interest rates. As of September 30, 2023 and 2022, we had $1,119.8 million and $1,143.3 million, respectively, in outstanding 
borrowings under our term credit agreements and our revolving credit facility. Interest on amounts borrowed under these agreements is 
subject to adjustment based on specified levels of financial performance. The applicable margin that is added to the borrowing in the 
base rate can range from 0.25% to 1.00% and the applicable margin that is added to borrowings in the eurocurrency rate can range from 
1.25%  to 2.00%.  For  the year  ended  September 30,  2023,  our weighted  average  floating rate  borrowings were $1,485.8 million, or 
$846.3 million excluding borrowings with effective fixed interest rates due to interest rate swap and interest rate cap agreements. If 
short-term  floating  interest  rates  had  increased  by  1.00%,  our  interest  expense  for  the  year  ended  September 30,  2023  would  have 
increased by $8.6 million. We invest our cash in a variety of financial instruments, consisting principally of money market securities or 
other highly liquid, short-term securities that are subject to minimal credit and market risk.

Report of Independent Registered Public Accounting Firm 

To the Stockholders and the Board of Directors of AECOM 

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of AECOM (the Company) as of September 30, 2023 and 2022, the 
related consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for each of the three years in 
the period ended September 30, 2023, and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively 
referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material 
respects, the financial position of the Company at September 30, 2023 and 2022, and the results of its operations and its cash flows for 
each of the three years in the period ended September 30, 2023, in conformity with U.S. generally accepted accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), 
the Company’s internal control over financial reporting as of September 30, 2023, based on criteria established in Internal Control-
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our 
report dated November 14, 2023 expressed an unqualified opinion thereon. 

Basis for Opinion 

These  financial  statements  are  the responsibility  of  the  Company’s management. Our responsibility  is  to  express  an opinion on  the 
Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to 
be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations 
of the Securities and Exchange Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit 
to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. 
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error 
or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding 
the  amounts  and  disclosures  in  the  financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and 
significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that 
our audits provide a reasonable basis for our opinion. 

Critical Audit Matter 

The  critical  audit  matter  communicated below  is  a  matter  arising from  the  current  period  audit of  the  financial  statements  that was 
communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material 
to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the 
critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by 
communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures 
to which it relates.

Revenue Recognition - Contract cost and claim recovery estimates 

Description of the 
Matter 

For  the  year  ended  September 30,  2023,  contract  revenues  recognized  by  the  Company  were  $14.4  billion. 
Contract  revenues  include  $3.4  billion  which  relate  to  fixed  price  contracts  and  $4.9  billion  which  relate  to 
guaranteed  maximum  price  contracts.  As  described  in  Note  4  of  the  consolidated  financial  statements,  the 
Company generally recognizes revenues for these contracts over time as performance obligations are satisfied. 
The  Company  generally  measures  its  progress  to  completion  using  an  input  measure  of  total  costs  incurred 
divided by total costs expected to be incurred. In addition, the Company’s estimate of transaction price includes 
variable consideration associated with claims only to the extent that a significant reversal would not be probable.

Recognition of revenue and profit over time as performance obligations are satisfied for long-term fixed price 
contracts is highly judgmental as it requires the Company to prepare estimates of total contract revenue and total 
contract costs, including costs to complete in-process contracts. These estimates are dependent upon a number of 
factors, including the accuracy of estimates made at the balance sheet date, such as engineering progress, material 
quantities, the achievement of milestones, penalty provisions, labor productivity and cost estimates. 

As  of  September 30,  2023,  significant  claims  recorded  in  contract  assets  and  other  non-current  assets  on  the 
consolidated balance sheet were approximately $160.0 million. Revenue recognition relating to claims is highly 
judgmental as the amount has been disputed by the customer and it requires the Company to prepare estimates of 
amounts expected to be recovered. Changes in recovery estimates can have a material effect on the amount of 
revenue recognized. 

Auditing contract revenue recognition is complex and highly judgmental due to the variability and uncertainty 
associated with estimating the costs to complete and amounts expected to be recovered from claims. Changes in 
these estimates would have a significant effect on the amount of contract revenue recognized. 

How We Addressed 
the Matter in Our 
Audit 

We  obtained  an  understanding,  evaluated  the  design,  and  tested  the  operating  effectiveness  of  controls  that 
address the risk of material misstatement of contract revenue including those associated with cost to complete 
estimates for long-term fixed price contracts and estimates of amounts expected to be recovered from claims. For 
example, we tested controls over the Company’s review of estimated direct and indirect costs to be incurred and 
estimates of claim recovery amounts. 

To evaluate the Company’s determination of estimated costs to complete, we selected a sample of contracts and, 
among  other  things,  inspected  the  executed  contracts  including  any  significant  amendments;  conducted 
interviews with and inspected questionnaires prepared by project personnel; tested key components of the cost to 
complete estimates, including materials, labor, and subcontractors costs; reviewed support for estimates of project 
contingencies;  compared  actual  project  margins  to  historical  and  expected  results;  and  recalculated  revenues 
recognized. 

To test revenue recognized relating to claims, we selected a sample of projects and evaluated the estimates made 
by management by reviewing documentation from management’s specialists and external counsel to support the 
amount  of  the  claim.  We  also  tested  management’s  estimation  process  by  performing  a  lookback  analysis  to 
evaluate claims settled in the current year compared to management’s prior year estimates.

Report of Independent Registered Public Accounting Firm 

To the Stockholders and the Board of Directors and Stockholders of AECOM 

Opinion on Internal Control Over Financial Reporting 

We have audited AECOM’s internal control over financial reporting as of September 30, 2023, based on criteria established in Internal 
Control —  Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (2013 
framework) (the COSO criteria). In our opinion, AECOM (the Company) maintained, in all material respects, effective internal control 
over financial reporting as of September 30, 2023, based on the COSO criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), 
the 2023 consolidated financial statements of the Company and our report dated November 14, 2023 expressed an unqualified opinion 
thereon. 

Basis for Opinion 

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of 
the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control 
over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based 
on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company 
in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission 
and the PCAOB. 

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. 

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness 
exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such 
other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. 

Definition and Limitations of Internal Control Over Financial Reporting 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting 
principles.  A  company’s  internal  control  over  financial  reporting  includes  those  policies  and  procedures  that  (1) pertain  to  the 
maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the 
company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in 
accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention 
or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the 
financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections 
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1.           Significant Accounting Policies 

Organization— AECOM and its consolidated subsidiaries provide planning, consulting, architectural and engineering design 
services to public and private clients worldwide in major end markets such as transportation, facilities, environmental, energy, water 
and  government.  The  Company  also  provides  construction  services,  including  building  construction  and  energy,  infrastructure  and 
industrial construction, primarily in the Americas.  

Fiscal  Year—The  Company  reports  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 year ended on September 30. Fiscal years 2023, 2022 and 
2021 each contained 52, 52 and 52 weeks, respectively, and ended on September 29, September 30, and October 1, respectively. Certain 
prior period amounts in the consolidated financial statements and accompanying notes have been reclassified to conform with the current 
period’s presentation. 

Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the 
United States (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities 
and  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  financial  statements  and  the  reported  amounts  of  revenues  and 
expenses during the reporting period. The more significant estimates affecting amounts reported in the consolidated financial statements 
relate to revenues under long-term contracts and self-insurance accruals. Actual results could differ from those estimates. 

Principles  of  Consolidation  and  Presentation—The  consolidated  financial  statements  include  the  accounts  of  all 
majority-owned subsidiaries and joint ventures in which the Company is the primary beneficiary. All inter-company accounts have been 
eliminated in consolidation. Also see Note 6 regarding joint ventures and variable interest entities. 

Government Contract Matters—The Company’s federal government and certain state and local agency contracts are subject 
to,  among  other  regulations,  regulations  issued  under  the  Federal  Acquisition  Regulations  (FAR).  These  regulations  can  limit  the 
recovery of certain specified indirect costs on contracts and subjects the Company to ongoing multiple audits by government agencies 
such  as  the  Defense  Contract  Audit  Agency  (DCAA). In  addition,  most of  the  Company’s  federal  and  state  and  local  contracts  are 
subject to termination at the discretion of the client. 

Audits  by  the  DCAA  and  other  agencies  consist  of  reviews  of  the  Company’s  overhead  rates,  operating  systems  and  cost 
proposals to ensure that the Company accounted for such costs in accordance with the Cost Accounting Standards of the FAR (CAS). 
If the DCAA determines the Company has not accounted for such costs consistent with CAS, the DCAA may disallow these costs. 
There can be no assurance that audits by the DCAA or other governmental agencies will not result in material cost disallowances in the 
future.  

Cash  and  Cash  Equivalents—The  Company’s  cash  equivalents  include  highly  liquid  investments  which  have  an  initial 

maturity of three months or less. 

Allowance for Doubtful Accounts—The Company records its accounts receivable net of an allowance for doubtful accounts. 
This  allowance  for  doubtful  accounts  is  estimated  based  on  management’s  evaluation  of  the  contracts  involved  and  the  financial 
condition of its clients. The factors the Company considers in its contract evaluations include, but are not limited to: 

•  Client type—federal or state and local government or commercial client; 

•  Historical contract performance; 

•  Historical collection and delinquency trends; 

•  Client credit worthiness; and

Derivative  Financial  Instruments—The  Company  accounts  for  its  derivative  instruments  as  either assets  or  liabilities  and 

carries them at fair value. 

For derivative instruments that hedge the exposure to variability in expected future cash flows that are designated as cash flow 
hedges,  the  effective  portion  of  the  gain  or  loss  on  the  derivative  instrument  is  reported  as  a  component  of  accumulated  other 
comprehensive  income  in  stockholders’  equity  and  reclassified  into  income  in  the same  period  or  periods during which  the hedged 
transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument, if any, is recognized in current 
income. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash 
flows on hedged transactions. 

The net gain or loss on the effective portion of a derivative instrument that is designated as an economic hedge of the foreign 
currency translation exposure generated by the re-measurement of certain assets and liabilities denominated in a non-functional currency 
in a foreign operation is reported in the same manner as a foreign currency translation adjustment. Accordingly, any gains or losses 
related to these derivative instruments are recognized in current income. 

Derivatives that do not qualify as hedges are adjusted to fair value through current income. 

Fair  Value  of  Financial  Instruments—The  Company  determines  the  fair  values  of  its  financial  instruments,  including 
short-term investments, debt instruments and derivative instruments, and pension and post-retirement plan assets based on inputs or 
assumptions  that  market  participants  would  use  in  pricing  an  asset  or  a  liability.  The  Company  categorizes  its  instruments  using  a 
valuation hierarchy for disclosure of the inputs used to measure fair value. This hierarchy prioritizes the inputs into three broad levels 
as follows: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 inputs are quoted 
prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly 
through market corroboration, for substantially the full term of the financial instrument; Level 3 inputs are unobservable inputs based 
on the Company’s assumptions used to measure assets and liabilities at fair value. The classification of a financial asset or liability 
within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. 

The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value because 
of the short maturities of these instruments. The carrying amount of the revolving credit facility approximates fair value because the 
interest rates are based upon variable reference rates. 

The  Company’s  fair  value  measurement  methods  may  produce  a  fair  value  calculation  that  may  not  be  indicative  of  net 
realizable value or reflective of future fair values. Although the Company believes its valuation methods are appropriate and consistent 
with those used by other market participants, the use of different methodologies or assumptions to determine fair value could result in a 
different fair value measurement at the reporting date. 

Property and Equipment—Property and equipment are recorded at cost and are depreciated over their estimated useful lives 
using the straight-line method. Expenditures for maintenance and repairs are expensed as incurred. Typically, estimated useful lives 
range from ten to forty-five years for buildings, three to ten years for furniture and fixtures and three to twelve years for  computer 
systems and equipment. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives 
or the remaining terms of the underlying lease agreement. 

Long-Lived Assets—Long-lived assets to be held and used are reviewed for impairment whenever events or circumstances 
indicate that the assets may not be recoverable. The carrying amount of an asset to be held and used is not recoverable if it exceeds the 
sum  of  the  undiscounted  cash  flows  expected  from  the  use  and  eventual  disposition  of  the  asset.  For  assets  to  be  held  and  used, 
impairment losses are recognized based upon the excess of the asset’s carrying amount over the fair value of the asset. For long-lived 
assets to be disposed, impairment losses are recognized at the lower of the carrying amount or fair value less cost to sell. 

Goodwill and Acquired Intangible Assets—Goodwill represents the excess of amounts paid over the fair value of net assets 
acquired from an acquisition. In order to determine the amount of goodwill resulting from an acquisition, the Company performs an 
assessment to determine the value of the acquired company’s tangible and identifiable intangible assets and liabilities. In its assessment, 
the  Company  determines  whether  identifiable  intangible  assets  exist,  which  typically  include  backlog  and  customer  relationships. 
Intangible assets are amortized over the period in which the contractual or economic benefits of the intangible assets are expected to be 
realized. 

64 

The Company tests goodwill for impairment annually for each reporting unit in the fourth quarter of the fiscal year and between 
annual tests, if events occur or circumstances change which suggest that goodwill should be evaluated. Such events or circumstances 
include significant changes in legal factors and business climate, recent losses at a reporting unit, and industry trends, among other 
factors. A reporting unit is defined as an operating segment or one level below an operating segment. The Company’s impairment tests 
are performed at the operating segment level as they represent the Company’s reporting units. 

Goodwill  is  evaluated  for  impairment  either  by  assessing  qualitative  factors  or  by  performing  a  quantitative  assessment. 
Qualitative factors, such as overall financial performance, industry or market considerations, or other relevant events, are assessed to 
determine if it is more likely than not that the fair value of the reporting units is less than their carrying amounts. During a quantitative 
impairment test, the Company estimates the fair value of the reporting unit using income and market approaches, and compares that 
amount to the carrying value of that reporting unit. In the event the fair value of the reporting unit is determined to be less than the 
carrying value, goodwill is impaired, and an impairment loss is recognized equal to the excess, limited to the total amount of goodwill 
allocated to the reporting unit. See also Note 3. 

Pension Plans—The Company has certain defined benefit pension plans. The Company calculates the market-related value of 
assets, which is used to determine the return-on-assets component of annual pension expense and the cumulative net unrecognized gain 
or loss subject to amortization. This calculation reflects the Company’s anticipated long-term rate of return and amortization of the 
difference  between  the  actual  return  (including  capital,  dividends,  and  interest)  and  the  expected  return  over  a  five-year  period. 
Cumulative net unrecognized gains or losses that exceed 10% of the greater of the projected benefit obligation or the fair market related 
value of plan assets are subject to amortization. 

Insurance  Reserves—The  Company  maintains  insurance  for  certain  insurable  business  risks.  Insurance  coverage  contains 
various  retention  and  deductible  amounts  for  which  the  Company  accrues  a  liability  based  upon  reported  claims  and  an  actuarially 
determined estimated liability for certain claims incurred but not reported. It is generally the Company’s policy not to accrue for any 
potential  legal  expense  to  be  incurred  in  defending  the  Company’s  position.  The  Company  believes  that  its  accruals  for  estimated 
liabilities associated with professional and other liabilities are sufficient and any excess liability beyond the accrual is not expected to 
have a material adverse effect on the Company’s results of operations or financial position. 

Foreign Currency Translation—The Company’s functional currency is generally the U.S. dollar, except for foreign operations 
where the functional currency is generally the local currency. Results of operations for foreign entities are translated to U.S. dollars 
using the average exchange rates during the period. Assets and liabilities for foreign entities are translated using the exchange rates in 
effect as of the date of the balance sheet. Resulting translation adjustments are recorded as a foreign currency translation adjustment into 
other accumulated comprehensive income/(loss) in stockholders’ equity. 

The Company uses foreign currency forward contracts from time to time to mitigate foreign currency risk. The Company limits 
exposure  to  foreign  currency  fluctuations  in  most  of  its  contracts  through  provisions  that  require  client  payments  in  currencies 
corresponding to the currency in which costs are incurred. As a result of this natural hedge, the Company generally does not need to 
hedge foreign currency cash flows for contract work performed. 

Noncontrolling Interests—Noncontrolling interests represent the equity investments of the minority owners in the Company’s 

joint ventures and other subsidiary entities that the Company consolidates in its financial statements. 

Income Taxes—The Company files a consolidated U.S. federal corporate income tax return and combined / consolidated state 
tax returns and separate company state tax returns. The Company accounts for certain income and expense items differently for financial 
reporting  and  income  tax purposes. Deferred  tax  assets  and  liabilities  are  determined based on  the  difference between  the  financial 
statement and tax basis of assets and liabilities, applying enacted statutory tax rates in effect for the year in which the differences are 
expected  to  reverse.  In  determining  the  need  for  a  valuation  allowance,  management  reviews  both  positive  and  negative  evidence, 
including the nature, frequency, and severity of cumulative financial reporting losses in recent years, the future reversal of existing 
temporary differences, predictability of future taxable income exclusive of reversing temporary differences of the character necessary 
to realize the asset, relevant carryforward periods, taxable income in carry-back years if carry-back is permitted under tax law, and 
prudent and feasible tax planning strategies that would be implemented, if necessary, to protect against the loss of the deferred tax asset 
that would otherwise expire. Based upon management’s assessment of all available evidence, the Company has concluded that it is more 
likely than not that the deferred tax assets, net of valuation allowance, will be realized.

On December 22, 2017, the United States enacted the Tax Cuts and Jobs Act, which significantly changed U.S. tax law and 
included a provision to tax global intangible low-taxed income (GILTI) of foreign subsidiaries. The Company recognizes taxes due 
under the GILTI provision as a current period expense. 

2.           New Accounting Pronouncements and Changes in Accounting 

In December 2019, the Financial Accounting Standards Board (FASB) issued new accounting guidance which simplifies the 
accounting for income taxes. The guidance amends certain exceptions to the general principles of Accounting Standards Codification 
(ASC) 740, Income Taxes, and simplifies several areas such as accounting for a franchise tax or similar tax that is partially based on 
income.  The  Company  adopted  the  new  guidance  starting  on  October 1,  2021.  The  adoption  of  the  new  guidance  did  not  have  a 
significant impact on the Company’s consolidated financial statements. 

In October 2021, the FASB issued final guidance to companies that apply ASC 606, Revenue from Contracts with Customers, 
to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination. The 
new guidance creates an exception to the general requirement to measure acquired assets and liabilities at fair value on the acquisition 
date.  Under  this  exception,  an  acquirer  applies  ASC  606  to  recognize  and  measure  contract  assets  and  contract  liabilities  on  the 
acquisition date. The Company adopted the new guidance starting on October 1, 2022 on a prospective basis and the revised guidance 
will be applied to any business combinations the Company undertakes. 

3.           Discontinued Operations, Goodwill, and Intangible Assets 

In  the  first  quarter  of  fiscal  2020,  management  approved  a  plan  to  dispose  of  via  sale  the  Company’s  self-perform  at-risk 
construction businesses. These businesses include the Company’s civil infrastructure, power, and oil and gas construction businesses 
that were previously reported in the Company’s Construction Services segment. After consideration of the relevant facts, the Company 
concluded the assets and liabilities of its self-perform at-risk construction businesses met the criteria for classification as held for sale. 
The Company concluded the actual and proposed disposal activities represented a strategic shift that would have a major effect on the 
Company’s operations and financial results and qualified for presentation as discontinued operations in accordance with FASB ASC 
205-20. Accordingly, the financial results of the self-perform at-risk construction businesses are presented in the Consolidated Statement 
of Operations as discontinued operations for all periods presented. Current and non-current assets and liabilities of these businesses not 
sold as of the balance sheet date are presented in the Consolidated Balance Sheets as assets and liabilities held for sale for both periods 
presented. 

The Company completed the sale of its civil infrastructure construction business to affiliates of Oroco Capital in the second 
quarter of fiscal 2021. In the first quarter of fiscal 2022, the Company recorded an additional $40.0 million loss primarily related to 
revisions of estimates for its working capital obligation to be paid and a contingent consideration receivable. In the second quarter of 
fiscal 2023, the Company recorded a $38.9 million loss related to a revised estimate of its contingent consideration receivable recognized 
at the sale. Under the terms of the sale agreement, the Company made the required cash payments and delivered the cash and cash 
equivalents, including cash in consolidated joint ventures, on the balance sheet at closing. As a result, the Company recorded the net 
cash impact of the sale as a use of cash in the investing section of its statement of cash flows. 

On  January 28,  2022,  the  Company  completed  the  sale  of  its  oil  and  gas  construction  business  to  affiliates  of  Graham 
Maintenance Services LP for a purchase price of $14 million, subject to cash, debt and working capital adjustments. The Company 
recorded a pre-tax gain of approximately $3.0 million on the sale, net of transaction costs. During the third quarter of fiscal 2023, the 
Company collected approximately $9.2 million cash payment for contingent consideration completing this transaction.

4.           Revenue Recognition 

The Company follows accounting principles for recognizing revenue upon the transfer of control of promised goods or services 
to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. The Company 
generally  recognizes  revenues  over  time  as  performance  obligations  are  satisfied.  The  Company  generally  measures  its  progress  to 
completion using an input measure of total costs incurred divided by total costs expected to be incurred, which it believes to be the best 
measure of progress towards completion of the performance obligation. In the course of providing its services, the Company routinely 
subcontracts for services and incurs other direct costs on behalf of its clients. These costs are passed through to clients and, in accordance 
with GAAP, are included in the Company’s revenue and cost of revenue. These pass-through revenues for the years ended September 30, 
2023, 2022 and 2021 were $7.7 billion, $6.8 billion and $7.2 billion, respectively.  

Recognition of revenue and profit is dependent upon a number of factors, including the accuracy of a variety of estimates made 
at the balance sheet date, such as engineering progress, material quantities, the achievement of milestones, penalty provisions, labor 
productivity and cost estimates. Additionally, the Company is required to make estimates for the amount of consideration to be received, 
including bonuses, awards, incentive fees, claims, unpriced change orders, penalties, and liquidated damages. Variable consideration is 
included  in  the  estimate  of  the  transaction  price  only  to  the  extent  that  a  significant  reversal  would  not  be  probable.  Management 
continuously monitors factors that may affect the quality of its estimates, and material changes in estimates are disclosed accordingly. 
Costs attributable to claims are treated as costs of contract performance as incurred. 

The following summarizes the Company’s major contract types:  

Cost Reimbursable Contracts 

Cost reimbursable  contracts include  cost-plus  fixed  fee,  cost-plus  fixed rate,  and  time-and-materials price  contracts. Under 
cost-plus contracts, the Company charges clients for its costs, including both direct and indirect costs, plus a negotiated fee or rate. The 
Company recognizes revenue based on actual direct costs incurred and the applicable fixed rate or portion of the fixed fee earned as of 
the balance sheet date. Under time-and-materials price contracts, the Company negotiates hourly billing rates and charges its clients 
based on the actual time that it expends on a project. In addition, clients reimburse the Company for materials and other direct incidental 
expenditures incurred in connection with its performance under the contract. The Company may apply a practical expedient to recognize 
revenue in the amount in which it has the right to invoice if its right to consideration is equal to the value of performance completed to 
date. 

Guaranteed Maximum Price Contracts (GMP) 

GMP contracts share many of the same contract provisions as cost-plus and fixed-price contracts. As with cost-plus contracts, 
clients are provided a disclosure of all the project costs, and a lump sum or percentage fee is separately identified. The Company provides 
clients with a guaranteed price for the overall project (adjusted for change orders issued by clients) and a schedule including the expected 
completion date. Cost overruns or costs associated with project delays in completion could generally be the Company’s responsibility.

For many of the Company’s commercial or residential GMP contracts, the final price is generally not established until the Company has 
subcontracted  a  substantial  percentage  of  the  trade  contracts  with  terms  consistent  with  the  master  contract,  and  it  has  negotiated 
additional  contractual  limitations,  such  as  waivers  of  consequential  damages  as  well  as  aggregate  caps  on  liabilities  and  liquidated 
damages. Revenue is recognized for GMP contracts as project costs are incurred relative to total estimated project costs. 

Fixed-Price Contracts 

Fixed-price contracts include both lump-sum and fixed-unit price contracts. Under lump-sum contracts, the Company performs 
all the work under the contract for a specified fee. Lump-sum contracts are typically subject to price adjustments if the scope of the 
project changes or unforeseen conditions arise. Under fixed-unit price contracts, the Company performs a number of units of work at an 
agreed price per unit with the total payment under the contract determined by the actual number of units delivered. Revenue is recognized 
for fixed-price contracts using the input method measured on a cost-to-cost basis as the Company believes this is the best measure of 
progress towards completion.

As of September 30, 2023, the Company had allocated $21.9 billion of transaction price to unsatisfied or partially satisfied 
performance obligations, of which approximately 55% is expected to be satisfied within the next twelve months and the remaining 45% 
thereafter.  

Contract  liabilities  represent  amounts  billed  to  clients  in  excess  of  revenue  recognized  to  date.  The  Company  recognized 
revenue of $1,043.7 million and $565.2 million during the years ended September 30, 2023 and 2022, respectively, that was included 
in contract liabilities as of September 30, 2022 and 2021, respectively.

The Company’s timing of revenue recognition may not be consistent with its rights to bill and collect cash from its clients. 
Those rights are generally dependent upon advance billing terms, milestone billings based on the completion of certain phases of work 
or when services are performed. The Company’s accounts receivables represent amounts billed to clients that have yet to be collected 
and represent an unconditional right to cash from its clients. Contract assets represent the amount of contract revenue recognized but 
not yet billed pursuant to contract terms or accounts billed after the balance sheet date. Contract liabilities represent billings as of the 
balance sheet date, as allowed under the terms of a contract, but not yet recognized as contract revenue pursuant to the Company’s 
revenue recognition policy.

Substantially all contract assets as of September 30, 2023 and September 30, 2022 are expected to be billed and collected within 
twelve  months,  except  for  claims.  Significant  claims  recorded  in  contract  assets  and  other  non-current  assets  were  approximately 
$160 million and $110 million as of September 30, 2023 and 2022, respectively. The asset related to the Deactivation, Demolition, and 
Removal Project retained from the MS Purchaser as defined in discussed in Note 18 is presented in prepaid expense and other current 
assets from continuing operations in the Consolidated Balance Sheet. Contract retentions represent amounts invoiced to clients where 
payments have been withheld from progress payments until the contracted work has been completed and approved by the client but 
nonetheless represent an unconditional right to cash. 

The Company considers a broad range of information to estimate expected credit losses including the related ages of past due 
balances,  projections  of  credit  losses  based  on  historical  trends,  and  collection  history  and  credit  quality  of  its  clients.  Negative 
macroeconomic trends or delays in payment of outstanding receivables could result in an increase in the estimated credit losses. 

No single client accounted for more than 10% of the Company’s outstanding receivables at September 30, 2023 and 2022. 

The Company sold trade receivables to financial institutions, of which $291.0 million and $240.3 million were outstanding as 
of September 30, 2023 and 2022, respectively. The Company does not retain financial or legal obligations for these receivables that 
would result in material losses. The Company’s ongoing involvement is limited to the remittance of customer payments to the financial 
institutions with respect to the sold trade receivables.

6.           Joint Ventures and Variable Interest Entities 

The Company’s joint ventures provide architecture, engineering, program management, construction management, operations 
and  maintenance  services,  and  invest  in  real  estate  projects.  Joint  ventures,  the  combination  of  two  or  more  partners,  are  generally 
formed for a specific project. Management of the joint venture is typically controlled by a joint venture executive committee, comprised 
of representatives from the joint venture partners. The joint venture executive committee normally provides management oversight and 
controls decisions which could have a significant impact on the joint venture. 

Some  of  the  Company’s  joint  ventures  have  no  employees  and  minimal  operating  expenses.  For  these  joint  ventures,  the 
Company’s employees perform work for the joint venture, which is then billed to a third-party customer by the joint venture. These joint 
ventures function as pass- through entities to bill the third-party customer. For consolidated joint ventures of this type, the Company 
records the entire amount of the services performed and the costs associated with these services, including the services provided by the 
other  joint  venture  partners,  in  the  Company’s  result  of  operations.  For  certain  of  these  joint  ventures  where  a  fee  is  added  by  an 
unconsolidated joint venture to client billings, the Company’s portion of that fee is recorded in equity in earnings of joint ventures. 

The  Company  also  has  joint  ventures  that  have  their  own  employees  and  operating  expenses,  and  to  which  the  Company 
generally makes a capital contribution. The Company accounts for these joint ventures either as consolidated entities or equity method 
investments based on the criteria further discussed below. 

The Company follows guidance on the consolidation of variable interest entities (VIEs) that requires companies to utilize a 
qualitative approach to determine whether it is the primary beneficiary of a VIE. The process for identifying the primary beneficiary of 
a VIE requires consideration of the factors that indicate a party has the power to direct the activities that most significantly impact the 
joint venture’s economic performance, including powers granted to the joint venture’s program manager, powers contained in the joint 
venture governing board and, to a certain extent, a company’s economic interest in the joint venture. The Company analyzes its joint 
ventures and classifies them as either: 

• 

• 

a VIE that must be consolidated because the Company is the primary beneficiary or the joint venture is not a VIE and the 
Company holds the majority voting interest with no significant participative rights available to the other partners; or 

a VIE that does not require consolidation and is treated as an equity method investment because the Company is not the 
primary beneficiary or the joint venture is not a VIE and the Company does not hold the majority voting interest. 

As part of the above analysis, if it is determined that the Company has the power to direct the activities that most significantly 
impact the joint venture’s economic performance, the Company considers whether or not it has the obligation to absorb losses or rights 
to receive benefits of the VIE that could potentially be significant to the VIE. 

Contractually required support provided to the Company’s joint ventures is discussed in Note 18.

During fiscal 2023, the Company initiated a process to explore strategic options for the AECOM Capital business, consistent 
with the Company's focus on its professional services business. During the third quarter of fiscal 2023, the Company identified indicators 
of impairment in the equity method investments held in its AECOM Capital segment. Specifically, the Company identified evidence 
that the carrying value of certain of the investments in its real estate portfolio were in excess of their fair values. The Company concluded 
it no longer had the intent to retain certain of these investments for a period of time sufficient to allow for an anticipated recovery in 
market value. In the third quarter of fiscal 2023, the Company recorded an impairment loss of $307.0 million to reduce the carrying 
value of these investments to their estimated fair values. This impairment did not relate to investments in respect of which affiliates of 
AECOM Capital provide advisory services or manage third party capital. AECOM Capital will continue to manage existing investment 
vehicles and investments in a manner consistent with their current obligations. Fair value was determined using Level 3 inputs such as 
forecasted cash flows and comparable sales prices. 

7.           Pension Benefit Obligations 

In the U.S., the Company sponsors various qualified defined benefit pension plans. Benefits under these plans generally are 
based  on  the  employee’s  years  of  creditable  service  and  compensation;  however,  all  U.S.  defined  benefit  plans  are  closed  to  new 
participants and have frozen accruals.  

The Company also sponsors various non-qualified plans in the U.S.; all of these plans are frozen. Outside the U.S., the Company 
sponsors various pension plans, which are appropriate to the country in which the Company operates, some of which are government 
mandated. 

The  following  tables  provide  reconciliations  of  the  changes  in  the  U.S.  and  international  plans’  benefit  obligations, 
reconciliations of the changes in the fair value of assets for the last three years ended September 30, and reconciliations of the funded 
status as of September 30 of each year.

Funding requirements for each pension plan are determined based on the local laws of the country where such pension plan 
resides. In certain countries, the funding requirements are mandatory while in other countries, they are discretionary. The Company 
currently intends to contribute $22.2 million to the international plans in fiscal 2024. The required minimum contributions for U.S. plans 
are  not  significant.  In  addition,  the  Company  may  make  discretionary  contributions.  The  Company  currently  intends  to  contribute 
$12.9 million to U.S. plans in fiscal 2024.

The Company’s domestic and foreign plans seek a competitive rate of return relative to an appropriate level of risk depending 
on the funded status and obligations of each plan and typically employ both active and passive investment management strategies. The 
Company’s risk management practices include diversification across asset classes and investment styles and periodic rebalancing toward 
asset  allocation  targets.  The  target  asset  allocation  selected  for  each  plan  reflects  a  risk/return  profile  that  the  Company  believes  is 
appropriate relative to each plan’s liability structure and return goals.

To develop the expected long-term rate of return on assets assumption, the Company considered the historical returns and the 
future expectations for returns for each asset class, as well as the target asset allocation of the pension portfolio and the diversification 
of the portfolio. This resulted in the selection of a 7.00% and 6.04% weighted-average long-term rate of return on assets assumption for 
the fiscal year ended September 30, 2023 for U.S. and non-U.S. plans, respectively.

Cash equivalents are mostly comprised of short-term money-market instruments and are valued at cost, which approximates 

fair value. 

For investment funds not traded on an active exchange, or if the closing price is not available, the trustee obtains indicative 
quotes  from  a  pricing  vendor,  broker,  or  investment  manager.  These  funds  are  categorized  as  Level 2  if  the  custodian  obtains

corroborated quotes from a pricing vendor or categorized as Level 3 if the custodian obtains uncorroborated quotes from a broker or 
investment manager. 

Fixed income investment funds, not traded on an active exchange, categorized as Level 2 are valued by the trustee using pricing 
models that use verifiable observable market data (e.g., interest rates and yield curves observable at commonly quoted intervals), bids 
provided by brokers or dealers, or quoted prices of securities with similar characteristics. 

Hedge funds categorized as Level 3 are valued based on valuation models that include significant unobservable inputs and 
cannot be corroborated using verifiable observable market data. Hedge funds are valued by independent administrators. Depending on 
the nature of the assets, the general partners or independent administrators use both the income and market approaches in their models. 
The market approach consists of analyzing market transactions for comparable assets while the income approach uses earnings or the 
net present value of estimated future cash flows adjusted for liquidity and other risk factors. As of September 30, 2023, there were no 
material changes to the valuation techniques. 

Common collective funds are valued based on net asset value (NAV) per share or unit as a practical expedient as reported by 
the  fund  manager,  multiplied  by  the  number  of  shares  or  units  held  as  of  the  measurement  date.  Accordingly,  these  NAV-based 
investments have been excluded from the fair value hierarchy. These collective investment funds have redemption notice periods and 
are redeemable at the NAV, less transaction fees. There are no significant unfunded commitments related to these investments. 

Multiemployer Pension Plans 

The Company participates in construction-industry multiemployer pension plans. Generally, the plans provide defined benefits 
to substantially all employees covered by collective bargaining agreements. Under the Employee Retirement Income Security Act, a 
contributor to a multiemployer plan is liable, upon termination or withdrawal from a plan, for its proportionate share of a plan’s unfunded 
vested liability. The Company’s aggregate contributions to these multiemployer plans were $3.0 million and $2.9 million for the years 
ended  September 30,  2023  and  2022,  respectively.  At  September 30,  2023  and  2022,  none  of  the  plans  in  which  the  Company 
participates are individually significant to its consolidated financial statements.

Credit Agreement 

On  February 8,  2021,  the  Company  entered  into  the  2021  Refinancing  Amendment  to  the  Credit  Agreement  (as  amended, 
modified or otherwise supplemented, the “Credit Agreement”), pursuant to which the Company amended and restated its Syndicated 
Credit Facility Agreement, dated as of October 17, 2014 (as amended prior to February 8, 2021, the “Original Credit Agreement”), 
between the Company, as borrower, Bank of America, N.A., as administrative agent, and other parties thereto. At the time of amendment, 
the Credit Agreement consisted of a $1,150,000,000 revolving credit facility (the “Revolving Credit Facility”) and a $246,968,737.50 
term loan A facility (the “Term A Facility,” together with the Revolving Credit Facility, the “Credit Facilities”), each of which mature 
on February 8, 2026. The outstanding loans under the Term A Facility were borrowed in U.S. dollars. Loans under the Revolving Credit 
Facility may be borrowed, and letters of credit thereunder may be issued, in U.S. dollars or in certain foreign currencies. The proceeds 
of the Revolving Credit Facility may be used from time to time for ongoing working capital and for other general corporate purposes. 
The proceeds of the Revolving Credit Facility and the Term A Loan facility borrowed on February 8, 2021 were used to refinance the 
existing revolving credit facility and the existing term loan facility under the Original Credit Agreement and to pay related fees and 
expenses. The Credit Agreement permits the Company to designate certain of its subsidiaries as additional co-borrowers from time to 
time. Currently, there are no co-borrowers under the Credit Facilities. 

On  April 13,  2021,  the  Company  entered  into  Amendment  No. 10  to  the  Credit  Agreement,  pursuant  to  which  the  lenders 
thereunder  provided  a  secured  term  B  credit  facility  (the  “Term  B  Facility”)  to  the  Company  in  an  aggregate  principal  amount  of 
$700,000,000. The Term B Facility matures on April 13, 2028. The proceeds of the Term B Facility were used to fund the purchase 
price, fees and expenses in connection with the Company’s cash tender offer to purchase up to $700,000,000 aggregate purchase price 
(not including any accrued and unpaid interest) of its outstanding 5.875% Senior Notes due 2024. 

On June 25, 2021, the Company entered into Amendment No. 11 to the Credit Agreement, pursuant to which lenders thereunder 
have provided the Company an additional $215,000,000 in aggregate principal amount under the Term A Facility. The Company used 
the net proceeds from the increase in the Term A Facility (together with cash on hand), to (i) redeem all of the Company’s remaining 
5.875% Senior Notes due 2024 and (ii) pay fees and expenses related to such redemption. 

On May 23, 2023, the Company entered into Amendment No. 12 to the Credit Agreement, pursuant to which LIBOR as a 
benchmark rate of interest was replaced by, in the case of US Dollar-denominated loans, a secured overnight financing rate subject to a 
spread adjustment, and, in the case of loans denominated in other currencies, other customary successor rates, subject in certain cases 
to a spread adjustment. On May 23, 2023, the Company entered into Amendment No. 13 to the Credit Agreement, pursuant to which 
the spread adjustments with respect to the Revolving Credit Facility and the Term A Facility was amended. 

The applicable interest rate for loans under the Term B Facility is calculated at a per annum rate equal to, at the Company’s 
option, (a) the Term SOFR (as defined in the Credit Agreement) plus 1.75% or (b) the Base Rate (as defined in the Credit Agreement) 
plus 0.75%. 

The applicable interest rate for U.S. Dollar-denominated loans under the Revolving Credit Facility and the Term A Facility  is 
calculated at a per annum rate equal to, at the Company’s option, (a) the Term SOFR (as defined in the Credit Agreement) plus an 
applicable  margin  (the  “SOFR  Applicable  Margin”),  which  is  currently  at  1.2250%  or  (b) the  Base  Rate  (as  defined  in  the  Credit 
Agreement)  plus  an  applicable  margin  (the  “Base  Rate  Applicable  Margin,”  and  together  with  the  SOFR  Applicable  Margin,  the 
“Applicable  Margins”),  which  is  currently  at  0.2250%.  The  applicable  interest  rate  for  loans  under  the  Revolving  Credit  Facility 
denominated in other currencies is calculated at a per annum rate equal to a customary floating reference rate for such currency specified 
in  the  Credit  Agreement  plus  the  SOFR  Applicable  Margin.  The  Credit  Agreement  includes  certain  environmental,  social  and 
governance (ESG) metrics relating to the Company’s CO2 emissions and its percentage of employees who identify as women (each, a 
“Sustainability Metric”). The Applicable Margins for the Term A Facility and the Revolving Credit Facility and the commitment fees 
for the Revolving Credit Facility will be adjusted on an annual basis based on the Company’s achievement of preset thresholds for each 
Sustainability Metric. 

Some of the Company’s material subsidiaries (the “Guarantors”) have guaranteed the Company’s obligations of the borrowers 
under the Credit Agreement, subject to certain exceptions. The borrowers’ obligations under the Credit Agreement are secured by a lien 
on substantially all of the Company’s assets and its Guarantors’ assets, subject to certain exceptions. 

The Credit Agreement contains customary negative covenants that include, among other things, limitations on the ability of the 
Company  and  certain  of  its  subsidiaries,  subject  to  certain  exceptions,  to  incur  liens  and  debt,  make  investments,  dispositions,  and 
restricted payments, change the nature of their business, consummate mergers, consolidations and the sale of all or substantially all of 

79 

their respective assets, taken as a whole, and transact with affiliates. The Company is also required to maintain a consolidated interest 
coverage ratio of at least 3.00 to 1.00 and a consolidated leverage ratio of less than or equal to 4.00 to 1.00 (subject to certain adjustments 
in connection with permitted acquisitions), tested on a quarterly basis (the “Financial Covenants”). The Financial Covenants do not 
apply to the Term B Facility. The Company’s consolidated leverage ratio was 2.00 to 1.00 at September 30, 2023. As of September 30, 
2023, the Company was in compliance with the covenants of the Credit Agreement. 

The Credit Agreement contains customary affirmative covenants, including, among other things, compliance with applicable 
law, preservation of existence, maintenance of properties and of insurance, and keeping proper books and records. The Credit Agreement 
contains customary events of default, including, among other things, nonpayment of principal, interest or fees, cross-defaults to other 
debt,  inaccuracies  of  representations  and  warranties,  failure  to  perform  covenants,  events  of  bankruptcy  and  insolvency,  change  of 
control and unsatisfied judgments, subject in certain cases to notice and cure periods and other exceptions. 

At September 30, 2023 and September 30, 2022, letters of credit totaled $4.4 million and $4.4 million, respectively, under our 
Revolving  Credit  Facility.  As  of  September 30,  2023  and  September 30,  2022,  we  had  $1,145.6  million  and  $1,145.6  million, 
respectively, available under our revolving credit facility. 

2027 Senior Notes 

On February 21, 2017, the Company completed a private placement offering of $1,000,000,000 aggregate principal amount of 
its unsecured 5.125% Senior Notes due 2027 (the “2027 Senior Notes”). On June 30, 2017, the Company completed an exchange offer 
to exchange the unregistered 2027 Senior Notes for registered notes, as well as related guarantees. 

As of September 30, 2023, the estimated fair value of the 2027 Senior Notes was approximately $939.9 million. The fair value 
of the 2027 Senior Notes as of September 30, 2023 was derived by taking the mid-point of the trading prices from an observable market 
input (Level 2) in the secondary bond market and multiplying it by the outstanding balance of the 2027 Senior Notes. Interest is payable 
on the 2027 Senior Notes at a rate of 5.125% per annum. Interest on the 2027 Senior Notes is payable semi-annually on March 15 and 
September 15 of each year, commencing on September 15, 2017. The 2027 Senior Notes will mature on March 15, 2027. 

At any time and from time to time prior to December 15, 2026, the Company may redeem all or part of the 2027 Senior Notes, 
at a redemption price equal to 100% of their principal amount, plus a “make whole” premium as of the redemption date, and accrued 
and unpaid interest to the redemption date. On or after December 15, 2026, the Company may redeem all or part of the 2027 Senior 
Notes at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest on the redemption date. 

The indenture pursuant to which the 2027 Senior Notes were issued contains customary events of default, including, among 
other things, payment default, exchange default, failure to provide notices thereunder and provisions related to bankruptcy events. The 
indenture also contains customary negative covenants. 

The Company was in compliance with the covenants relating to the 2027 Senior Notes as of September 30, 2023. 

Other Debt and Other Items 

Other debt consists primarily of obligations under capital leases and loans, and unsecured credit facilities. The Company’s 
unsecured credit facilities are primarily used for standby letters of credit issued in connection with general and professional liability 
insurance programs and for contract performance guarantees. At September 30, 2023 and September 30, 2022, these outstanding standby 
letters of credit totaled $878.9 million and $640.3 million, respectively. As of September 30, 2023, the Company had $416.7 million 
available under these unsecured credit facilities.  

Effective Interest Rate 

The Company’s average effective interest rate on its total debt, including the effects of the interest rate swap and interest rate 

cap agreements, during the years ended September 30, 2023, 2022 and 2021 was 5.3%, 3.8% and 4.4%, respectively. 

Interest expense in the consolidated statements of operations included amortization of deferred debt issuance costs for the years 

ended September 30, 2023, 2022 and 2021 of $4.9 million, $4.9 million and $10.2 million, respectively.

9.           Derivative Financial Instruments and Fair Value Measurements 

The Company uses interest rate derivative contracts to hedge interest rate exposures on the Company’s variable rate debt. The 
Company enters into foreign currency derivative contracts with financial institutions to reduce the risk that its cash flows and earnings 
will be adversely affected by foreign currency exchange rate fluctuations. The Company’s hedging program is not designated for trading 
or speculative purposes. 

The Company recognizes derivative instruments as either assets or liabilities on the accompanying consolidated balance sheets 
at  fair  value.  The  Company  records  changes  in  the  fair  value  (i.e., gains  or  losses)  of  the  derivatives  that  have  been  designated  as 
accounting hedges in the accompanying consolidated statements of operations as cost of revenue, interest expense or to accumulated 
other comprehensive loss in the accompanying consolidated balance sheets. 

Cash Flow Hedges 

The Company uses interest rate swap and interest rate cap agreements designated as cash flow hedges to limit exposure to 
variable interest rates on portions of the Company’s debt. The Company initially reports any gain on the effective portion of a cash flow 
hedge as a component of accumulated other comprehensive loss. Depending on the type of cash flow hedge, the gain is subsequently 
reclassified against interest expense when the interest expense on the variable rate debt is recognized. If the hedged transaction becomes 
probable of not occurring, any gain or loss related to interest rate swap or interest rate cap agreements would be recognized in other 
income. 

During the third quarter of fiscal 2023, the hedged debt index was changed from LIBOR to SOFR. The notional principal, fixed 

rates and related effective and expiration dates of the Company’s outstanding interest rate swap agreements were as follows:

In  the  fourth quarter of  fiscal  2021,  the  Company  entered  into new  interest  rate swap agreements  with  a  notional value of 
$400.0 million to manage the interest rate exposure of its variable rate loans. The new swaps will become effective February 2023 and 
terminate in March 2028. By entering into the swap agreements, the Company converted a portion of the SOFR rate-based liability into 
a fixed rate liability. The Company will pay a fixed rate of 1.283% and receive payment at the prevailing one-month SOFR. 

In the third quarter of fiscal 2022, the Company purchased interest rate cap agreements with a notional value of $300.0 million 
to manage interest rate exposure of its variable rate loans. The caps became effective on June 30, 2022 and terminate in March 2028. 
The caps reduce the Company’s exposure to one-month SOFR. In the event one-month SOFR exceeds 3.465%, the Company will pay 
the spread between prevailing one-month SOFR and 3.465%. 

Other Foreign Currency Forward Contracts 

The Company uses foreign currency forward contracts which are not designated as accounting hedges to hedge intercompany 
transactions and other monetary assets or liabilities denominated in currencies other than the functional currency of a subsidiary. Gains 
and losses on these contracts were not material for the years ended September 30, 2023, 2022 and 2021.  

Fair Value Measurements 

The Company’s non-pension financial assets and liabilities recorded at fair value relate to the interest rate swap and interest 
rate cap agreements included in other current assets and other non-current assets on September 30, 2023 and were $17.2 million and 
$37.5 million, respectively. The fair values of the interest rate swap and interest rate cap agreements included in other current assets and 
other non-current assets on September 30, 2022 were $9.4 million and $41.8 million, respectively. The fair values of the interest rate

swap and interest rate cap agreements were derived by taking the net present value of the expected cash flows using observable market 
inputs (Level 2) such as SOFR rate curves, futures, volatilities and basis spreads (when applicable). 

See  Note  17  for  accumulated  balances  and  reporting  period  activities  of  derivatives  related  to  reclassifications  out  of 
accumulated other comprehensive income for the years ended September 30, 2023, 2022 and 2021. Additionally, there were no material 
losses recognized in income due to amounts excluded from effectiveness testing from the Company’s interest rate swap agreements. 

10.         Concentration of Credit Risk 

Financial  instruments  which  potentially  subject  the  Company  to  concentrations  of  credit  risk  consist  principally  of  cash 
investments and trade receivables. The Company’s cash balances and short-term investments are maintained in accounts held by major 
banks and financial institutions located primarily in the U.S., Canada, Europe, Australia, Middle East and Hong Kong. If the Company 
extends significant credit to clients in a specific geographic area or industry, the Company may experience disproportionately high levels 
of default if those clients are adversely affected by factors particular to their geographic area or industry. Concentrations of credit risk 
with respect to trade receivables are limited due to the large number of customers comprising the Company’s customer base, including, 
in  large  part,  governments,  government  agencies  and  quasi-government  organizations,  and  their  dispersion  across  many  different 
industries  and  geographies.  See  Note 4  regarding  the  Company’s  foreign  revenues.  In  order  to  mitigate  credit  risk,  the  Company 
continually reviews the credit worthiness of its major private clients. 

11.         Leases 

The  Company  and  its  subsidiaries  are  lessees  in  non-cancelable  leasing  agreements  for  office  buildings  and  equipment. 
Substantially all of the Company’s office building leases are operating leases, and its equipment leases are both operating and finance 
leases. The Company groups lease and non-lease components for its equipment leases into a single lease component but separates lease 
and non-lease components for its office building leases. 

The Company recognizes a right-of-use asset and lease liability for its operating leases at the commencement date equal to the 
present value of the contractual minimum lease payments over the lease term. The present value is calculated using the rate implicit in 
the lease, if known, or the Company’s incremental secured borrowing rate. The discount rate used for operating leases is primarily 
determined based on an analysis of the Company’s incremental secured borrowing rate, while the discount rate used for finance leases 
is primarily determined by the rate specified in the lease. 

The related lease payments are expensed on a straight-line basis over the lease term, including, as applicable, any free-rent 
period during which the Company has the right to use the asset. For leases with renewal options where the renewal is reasonably assured, 
the lease term, including the renewal period, is used to determine the appropriate lease classification and to compute periodic rental 
expense. Leases with initial terms shorter than 12 months are not recognized on the balance sheet, and lease expense is recognized on a 
straight-line basis. 

During the fourth quarter of fiscal 2023, the Company approved a restructuring plan primarily to optimize its office real estate 
portfolio  with  its  freedom  to  grow  strategy,  which  initiated  a  review  of  the  carrying  value  of  right-of-use  assets  and  leasehold 
improvements. In connection with the review, the Company identified leased assets that were no longer recoverable. The Company 
recorded an impairment charge of  $86.2 million to reduce its right-of-use assets and leasehold improvements to their fair values and 
recorded the expense in restructuring costs on the Consolidated Statement of Operations. Fair value was determined primarily using 
Level 3 inputs, such as discounted cash flows. 

The components of lease expenses are as follows:

12.         Stockholders’ Equity 

Common  Stock  Units—Common  stock  units  are  only  redeemable  for  common  stock.  In  the  event  of  liquidation  of  the 

Company, holders of stock units are entitled to no greater rights than holders of common stock. See also Note 13. 

13.         Share-Based Payments 

Defined  Contribution  Plans—Substantially  all  permanent  domestic  employees  are  eligible  to  participate  in  defined 
contribution plans provided by the Company. Under these plans, participants may make contributions into a variety of funds, including 
a  fund  that  is  fully  invested  in  Company  stock.  Employees  are  not  required  to  allocate  any  funds  to  Company  stock;  however,  the 
Company does provide an annual Company match in AECOM shares. Employees may generally reallocate their account balances on a 
daily basis; however, employees classified as insiders are restricted under the Company’s insider trading policy. Compensation expense 
for the employer contributions related to AECOM stock issued under defined contribution plans during fiscal years ended September 30, 
2023, 2022 and 2021 was $23.1 million, $22.7 million, and $26.1 million, respectively.  

Stock  Incentive  Plans—Under  the  2020  Stock  Incentive  Plan,  the  Company  has  up  to  10.2 million  securities  remaining 
available for future issuance as of September 30, 2023. Stock options may be granted to employees and non-employee directors with an 
exercise price not less than the fair market value of the stock on the date of grant.  Unexercised options expire seven years after date of 
grant.  

The fair value of the Company’s employee stock option awards is estimated on the date of grant. The expected term of awards 
granted represents the period of time the awards are expected to be outstanding. The risk-free interest rate is based on U.S. Treasury 
bond rates with maturities equal to the expected term of the option on the grant date. The Company uses historical data as a basis to 
estimate the probability of forfeitures. 

The Company grants stock units to employees under its Performance Earnings Program (PEP), whereby units are earned and 
issued dependent upon meeting established cumulative performance objectives and vest over a three-year service period. Additionally, 
the Company issues restricted stock units to employees which are earned based on service conditions. The grant date fair value of PEP 
awards and restricted stock unit awards is primarily based on that day’s closing market price of the Company’s common stock. 

Restricted stock unit, PEP unit, and Stock Option activity for the year ended September 30 was as follows:

During fiscal 2023, valuation allowances in the amount of $21.0 million related to the AECOM Capital impairment charge 

were established for the portion of the charge that is not expected to be realized. 

During fiscal 2022, valuation allowances in the amount of $21.9 million primarily related to net operating losses in certain 
foreign entities were released due to sufficient positive evidence. The positive evidence included a realignment of the Company’s global 
transfer pricing methodology which resulted in forecasting the utilization of the net operating losses within the foreseeable future.

During fiscal 2021, the United Kingdom enacted a corporate tax rate increase from 19% to 25% beginning April 2023 requiring 
deferred tax assets and liabilities to be remeasured. The remeasurement resulted in a $25.9 million tax benefit, which is included in tax 
rate changes above. 

During fiscal 2021, the Company partially settled its U.S. federal audit for fiscal 2015 and 2016 and recorded tax expense of 

$13.2 million due primarily to changes in tax attributes. 

The  Company  is  currently  under  tax  audit  in  several  jurisdictions  including  the  U.S.  and  believe  the  outcomes  which  are 
reasonably possible within the next twelve months, including lapses in statutes of limitations, could result in adjustments, but will not 
result in a material change in the liability for uncertain tax positions. 

Generally, the Company would reverse its valuation allowance in a particular tax jurisdiction if the positive evidence examined, 
such as projected and sustainable earnings or a tax-planning strategy that allows for the usage of the deferred tax asset, is sufficient to 
overcome significant negative evidence, such as large net operating loss carryforwards or a cumulative history of losses in recent years. 
In the United States, the valued deferred tax assets have a restricted life or use under relevant tax law and, therefore, it is unlikely that 
the valuation allowance related to these assets will reverse. In addition, the Company is continually investigating tax planning strategies 
that, if prudent and feasible, may be implemented to realize a deferred tax asset that would otherwise expire unutilized. The identification 
and internal/external approval (as relevant) of such a prudent and feasible tax planning strategy could cause a reduction in the valuation 
allowance. 

The deferred tax assets (liabilities) are as follows:

As of September 30, 2023, and 2022, the Company has available unused federal, foreign and state net operating loss (NOL) 
carryforwards of $757.5 million and $848.0 million, respectively, which expire at various dates over the next several years and capital 
loss carryforwards of $199.4 million and $205.2 million, respectively, which mostly expire in 2025; some foreign NOL carryforwards 
never expire. In addition, as of September 30, 2023, the Company has unused state and foreign research and development credits of 
$27.2 million and $9.6 million, respectively, and other credits of $10.4 million which expire at various dates over the next several years. 

As  of  September 30,  2023  and  2022,  gross  deferred  tax  assets  were  $773.7  million  and  $723.4  million,  respectively.  The 
Company has recorded a valuation allowance of $171.2 million and $154.4 million as of September 30, 2023 and 2022, respectively,

primarily related to foreign and state net operating loss carryforwards, capital loss carryforwards, tax credits and other deferred tax 
assets. The Company has performed an assessment of positive and negative evidence, including the nature, frequency, and severity of 
cumulative financial reporting losses in recent years, the future reversal of existing temporary differences, predictability of future taxable 
income exclusive of reversing temporary differences of the character necessary to realize the asset, relevant carryforward periods, taxable 
income in carry-back years if carry-back is permitted under tax law, and prudent and feasible tax planning strategies that would be 
implemented, if necessary, to protect against the loss of the deferred tax asset that would otherwise expire. Although realization is not 
assured, based on the Company’s assessment, the Company has concluded that it is more likely than not that the remaining gross deferred 
tax asset (exclusive of deferred tax liabilities) of $602.5 million will be realized and, as such, no additional valuation allowance has been 
provided. The net increase in the valuation allowance of $16.8 million is primarily attributable to an increase in valuation allowances of 
$21.0 million related to the AECOM Capital impairment charge in the US, a decrease in valuation allowances on foreign net operating 
losses and currency translation adjustments of $3.3 million, and decreases in valuation allowances of $0.9 million related to state net 
operating losses and credits. 

Generally, the Company does not provide for U.S. taxes or foreign withholding taxes on gross book-tax differences in its non-
U.S. subsidiaries because such basis differences of approximately $1.3 billion are able to and intended to be reinvested indefinitely. If 
these basis differences were distributed, foreign tax credits could become available under current law to partially or fully reduce the 
resulting U.S. income tax liability. There may also be additional U.S. or foreign income tax liability upon repatriation, although the 
calculation of such additional taxes is not practicable.  

As of September 30, 2023, and 2022, the Company had a liability for unrecognized tax benefits, including potential interest 
and penalties, net of related tax benefit, totaling $79.5 million and $70.5 million, respectively. The gross unrecognized tax benefits as 
of September 30, 2023 and 2022 were $62.1 million and $55.2 million, respectively, excluding interest, penalties, and related tax benefit. 
Of the $62.1 million, approximately $60.7 million would be included in the effective tax rate if recognized. A reconciliation  of the 
beginning and ending amount of gross unrecognized tax benefits is as follows:

The  Company  classifies  interest  and  penalties  related  to  uncertain  tax  positions  within  the  income  tax  expense  line  in  the 
accompanying consolidated statements of operations. As of September 30, 2023, the accrued interest and penalties were $24.4 million 
and $1.5 million, respectively, excluding any related income tax benefits. As of September 30, 2022, the accrued interest and penalties 
were $20.5 million and $1.7 million, respectively, excluding any related income tax benefits. 

The Company files income tax returns in numerous tax jurisdictions, including the U.S., and numerous U.S. states and non-
U.S. jurisdictions around the world. The statute of limitations varies by jurisdiction in which the Company operates. Because of the 
number of jurisdictions in which the Company files tax returns, in any given year the statute of limitations in certain jurisdictions may 
expire without examination within the 12-month period from the balance sheet date. 

While it is reasonably possible that the total amounts of unrecognized tax benefits could significantly increase or decrease 

within the next twelve months, an estimate of the range of possible change cannot be made.  

15.         Earnings Per Share 

Basic  earnings  per  share  (EPS)  excludes  dilution  and  is  computed  by  dividing  net  income  attributable  to  AECOM  by  the 
weighted average number of common shares outstanding for the period. Diluted EPS is computed by dividing net income attributable 
to AECOM by the weighted average number of common shares outstanding and potential common shares for the period. The Company

includes as potential common shares the weighted average dilutive effects of equity awards using the treasury stock method. For the 
periods presented, equity awards excluded from the calculation of potential common shares were not significant.

2023 and 2022. The Company did not have material revisions to estimates for contracts where revenue is recognized using the input 
method during the twelve months ended September 30, 2023 and 2022. For the year ended September 30, 2023, the Company incurred 
restructuring expenses of $188.4 million, included personnel and other costs of $91.6 million and real estate costs of $96.8 million, of 
which $53.3 million was accrued and unpaid at September 30, 2023. During the year ended September 30, 2022, the Company incurred 
restructuring expenses of $107.5 million, of which $69.1 million was related to the exit of our Russia-related businesses. The remaining 
$38.4  million  related  to  actions  to  improve  margins  and  deliver  efficiencies.  These  expenses  included  personnel  and  other  costs  of 
$27.5 million and real estate costs of $10.9 million, of which $7.9 million was accrued and unpaid at September 30, 2022.  

On September 13, 2023, the Company’s Board of Directors declared a quarterly cash dividend of $0.18 per share, which was 
paid on October 20, 2023 to stockholders of record as of the close of business on October 5, 2023. As of September 30, 2023, accrued 
and unpaid dividends totaled $26.7 million and were classified within other accrued expenses on the consolidated balance sheet.

18.         Commitments and Contingencies 

The Company records amounts representing its probable estimated liabilities relating to claims, guarantees, litigation, audits 
and investigations. The Company relies in part on qualified actuaries to assist it in determining the level of reserves to establish for 
insurance-related claims that are known and have been asserted against it, and for insurance-related claims that are believed to have 
been incurred based on actuarial analysis, but have not yet been reported to the Company’s claims administrators as of the respective 
balance sheet dates. The Company includes any adjustments to such insurance reserves in its consolidated results of operations. The 
Company’s reasonably possible loss disclosures are presented on a gross basis prior to the consideration of insurance recoveries. The 
Company does not record gain contingencies until they are realized. In the ordinary course of business, the Company may not be aware 
that it or its affiliates are under investigation and may not be aware of whether or not a known investigation has been concluded. 

In  the  ordinary  course  of  business,  the  Company  may  enter  into  various  arrangements  providing  financial  or  performance 
assurance to clients, lenders, or partners. Such arrangements include standby letters of credit, surety bonds, and corporate guarantees to 
support the creditworthiness or the project execution commitments of its affiliates, partnerships and joint ventures. The Company’s 
unsecured credit arrangements are used for standby letters of credit issued in connection with general and professional liability insurance 
programs and for contract performance guarantees. At September 30, 2023 and 2022, these outstanding standby letters of credit totaled 
$878.9 million and $640.3 million, respectively. As of September 30, 2023, the Company had $416.7 million available under these 
unsecured credit facilities. Performance arrangements typically have various expiration dates ranging from the completion of the project 
contract and extending beyond contract completion in some circumstances such as for warranties. The Company may also guarantee 
that  a  project,  when  complete,  will  achieve  specified  performance  standards.  If  the  project  subsequently  fails  to  meet  guaranteed 
performance standards, the Company may incur additional costs, pay liquidated damages or be held responsible for the costs incurred 
by the client to achieve the required performance standards. The potential payment amount of an outstanding performance arrangement 
is typically the remaining cost of work to be performed by or on behalf of third parties. Generally, under joint venture arrangements, if 
a partner is financially unable to complete its share of the contract, the other partner(s) may be required to complete those activities.

At September 30, 2023, the Company was contingently liable in the amount of approximately $883.3 million in issued standby 

letters of credit and $4.6 billion in issued surety bonds primarily to support project execution. 

In the ordinary course of business, the Company enters into various agreements providing financial or performance assurances 
to clients on behalf of certain unconsolidated partnerships, joint ventures and other jointly executed contracts. These agreements are 
entered into primarily to support the project execution commitments of these entities.  

The Company’s investment adviser jointly manages and sponsors the AECOM-Canyon Equity Fund, L.P. (the “Fund”), in 
which the Company indirectly holds an equity interest and has an ongoing capital commitment to fund investments. At September 30, 
2023, the Company has capital commitments of $8.3 million to the Fund over the next 5 years. 

In  addition,  in  connection  with  the  investment  activities  of  AECOM  Capital,  the  Company  provides  guarantees  of  certain 
contractual obligations, including guarantees for completion of projects, repayment of debt, environmental indemnity obligations and 
other lender required guarantees. 

Department of Energy Deactivation, Demolition, and Removal Project 

A  former  affiliate  of  the  Company,  Amentum  Environment &  Energy,  Inc.,  f/k/a  AECOM  Energy  and  Construction,  Inc. 
(“Former Affiliate”), executed a cost-reimbursable task order with the Department of Energy (DOE) in 2007 to provide deactivation, 
demolition and removal services at a New York State project site that, during 2010, experienced contamination and performance issues. 
In February 2011, the Former Affiliate and the DOE executed a Task Order Modification that changed some cost-reimbursable contract 
provisions to at-risk. The Task Order Modification, including subsequent amendments, required the DOE to pay all project costs up to 
$106 million, required the Former Affiliate and the DOE to equally share in all project costs incurred from $106 million to $146 million, 
and required the Former Affiliate to pay all project costs exceeding $146 million.  

Due to unanticipated requirements and permitting delays by federal and state agencies, as well as delays and related ground 
stabilization activities caused by Hurricane Irene in 2011, the Former Affiliate was required to perform work outside the scope of the 
Task Order Modification. In December 2014, the Former Affiliate submitted an initial set of claims against the DOE pursuant to the 
Contracts Disputes Acts seeking recovery of $103 million, including additional fees on changed work scope (the “2014 Claims”). On 
December 6,  2019,  the  Former  Affiliate  submitted  a  second  set  of  claims  against  the  DOE  seeking  recovery  of  an  additional 
$60.4 million, including additional project costs and delays outside the scope of the contract as a result of differing site and ground 
conditions (the “2019 Claims”). The Former Affiliate also submitted three alternative breach of contract claims to the 2014 and 2019 
Claims that may entitle the Former Affiliate to recovery of $148.5 million to $329.4 million. On December 30, 2019, the DOE denied 
the Former Affiliate’s 2014 Claims. On September 25, 2020, the DOE denied the Former Affiliate’s 2019 Claims. The Company filed 
an appeal of these decisions on December 20, 2020 in the Court of Federal Claims. Deconstruction, decommissioning and site restoration 
activities are complete. 

On January 31, 2020, the Company completed the sale of its Management Services business, including the Former Affiliate 
who worked on the DOE project, to Maverick Purchaser Sub LLC (MS Purchaser), an affiliate of American Securities LLC and Lindsay 
Goldberg LLC. The Company and the MS Purchaser agreed that all future DOE project claim recoveries and costs will be split 10% to 
the MS Purchaser and 90% to the Company with the Company retaining control of all future strategic legal decisions. 

The Company intends to vigorously pursue all claimed amounts but can provide no certainty that the Company will recover 
2014  Claims  and 2019  Claims  submitted against  the DOE,  or any  additional  incurred  claims  or  costs,  which  could  have  a material 
adverse effect on the Company’s results of operations. 

Refinery Turnaround Project  

A Former Affiliate of the Company entered into an agreement to perform turnaround maintenance services during a planned 
shutdown at a refinery in Montana in December 2017. The turnaround project was completed in February 2019. Due to circumstances 
outside  of  the  Company’s  Former  Affiliate’s  control,  including  client  directed  changes  and  delays  and  the  refinery’s  condition,  the 
Company’s Former Affiliate performed additional work outside of the original contract over  $90 million and is entitled to payment 
from  the  refinery  owner  of  approximately  $144  million.  In  March 2019,  the  refinery  owner  sent  a  letter  to  the  Company’s  Former 
Affiliate alleging it incurred approximately $79 million in damages due to the Company’s Former Affiliate’s project performance. In 
April 2019, the Company’s Former Affiliate filed and perfected a $132 million construction lien against the refinery for unpaid labor 
and  materials  costs.  In  August 2019,  following  a  subcontractor  complaint  filed  in  the  Thirteen  Judicial  District  Court  of  Montana 

90 

asserting claims against the refinery owner and the Company’s Former Affiliate, the refinery owner crossclaimed against the Company’s 
Former Affiliate and the subcontractor. In October 2019, following the subcontractor’s dismissal of its claims, the Company’s Former 
Affiliate removed the matter to federal court and cross claimed against the refinery owner. In December 2019, the refinery owner claimed 
$93.0 million in damages and offsets against the Company’s Former Affiliate. 

On January 31, 2020, the Company completed the sale of its Management Services business, including the Former Affiliate, 
to  the  MS  Purchaser;  however,  the  Refinery  Turnaround  Project,  including  related  claims  and  liabilities,  has  been  retained  by  the 
Company. 

The Company intends to vigorously prosecute and defend this matter; however, the Company cannot provide assurance that 
the Company will be successful in these efforts. The resolution of this matter and any potential range of loss cannot be reasonably 
determined or estimated at this time, primarily because the matter raises complex legal issues that Company is continuing to assess. 

19.         Reportable Segments and Geographic Information 

The Company’s reportable segments are presented according to their geographic regions and business activities. The Americas 
segment provides planning, consulting, architectural and engineering design services, and construction management services to public 
and  private  clients  in  the  United  States,  Canada,  and  Latin  America,  while  the  International  segment  provides  similar  professional 
services to public and private clients in Europe, the Middle East, India, Africa, and the Asia-Australia-Pacific regions. 

The Company’s AECOM Capital (ACAP) segment primarily invests in and develops real estate projects. These reportable 
segments are organized by the differing specialized needs of the respective clients, and how the Company manages its business. The 
Company has aggregated various operating segments into its reportable segments based on their similar characteristics, including similar 
long term financial performance, the nature of services provided, internal processes for delivering those services, and types of customers.

DISCLOSURE

ITEM 9A.  CONTROLS AND PROCEDURES 

Evaluation of Disclosure Controls and Procedures 

Based on management’s evaluation, with the participation of our Chief Executive Officer (CEO) and Chief Financial Officer 
(CFO),  our  CEO  and  CFO  have  concluded  that  our  disclosure  controls  and  procedures  as  defined  in  Rules 13a-15(e) and 
15(d)-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act), were effective as of September 30, 2023 to ensure 
that information required to be disclosed by us in this Annual Report on Form 10-K or submitted under the Exchange Act is (i) recorded, 
processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms, and 
(ii) accumulated and communicated to our management, including our principal executive and principal financial officer, as appropriate, 
to allow timely decisions regarding required disclosures. 

Management’s Report on Internal Control over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal 
control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934, as 
amended, as a process designed by, or under the supervision of, the company’s principal executive and principal financial officers and 
effected by the company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability 
of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting 
principles. Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records 
that  in  reasonable  detail  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the  company;  (ii) provide 
reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with 
generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with 
authorizations  of  management  and  directors  of  the  company;  and  (iii) provide  reasonable  assurance  regarding  prevention  or  timely 
detection  of  unauthorized  acquisition,  use  or  disposition  of  the  company’s  assets  that  could  have  a  material  effect  on  the  financial 
statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections 
of any evaluation of the effectiveness to future periods are subject to the risk that controls may become inadequate because of changes 
in conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

Our management, with the participation of our CEO and CFO, assessed the effectiveness of our internal control over financial 
reporting as of September 30, 2023, the end of our fiscal year. Our management based its assessment on criteria established in Internal 
Control—Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.  Our 
management’s assessment included evaluation and testing of the design and operating effectiveness of key financial reporting controls, 
process documentation, accounting policies, and our overall control environment. 

Based on our management’s assessment, our management has concluded that our internal control over financial reporting was 
effective as of September 30, 2023. Our management communicated the results of its assessment to the Audit Committee of our Board 
of Directors. 

Our independent registered public accounting firm, Ernst & Young LLP, audited our financial statements for the fiscal year 
ended September 30, 2023 included in this Annual Report on Form 10-K, and has issued an audit report with respect to the effectiveness 
of the Company’s internal control over financial reporting, a copy of which is included earlier in this Annual Report on Form 10-K. 

Changes in Internal Control Over Financial Reporting 

There were  no  changes  in our  internal  control over  financial  reporting during  the fiscal  quarter  ended  September 30, 2023 
identified in connection with the evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act that have 
materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 9B.  OTHER INFORMATION 

During the quarterly period ended September 30, 2023, no director or officer of the Company adopted or terminated a Rule 

10b5-1 trading arrangement or a non-Rule 10b5-1 trading arrangement as each term is defined in Item 408(a) of Regulation S-K. 

As previously reported on our Form 8-K filed March 31, 2023, disclosing the Company’s 2023 Annual Meeting of Stockholders 
(“2023 Annual Meeting”) results, the holders of a majority of the shares of common stock present in person or represented by proxy and 
entitled to vote on the proposal voted to hold future advisory votes on the Company’s executive compensation every year. In light of 
these results and in accordance with its previous recommendation in the proxy statement for the 2023 Annual Meeting, the Company’s 
Board  of  Directors  (the  “Board”)  determined  that  the  Company  will  hold  future  advisory  votes  on  the  approval  of  executive 
compensation of the Company’s named executive officers on an annual basis. The Board will reevaluate this determination after the 
next shareholder advisory vote on the frequency of future advisory votes on approval of executive compensation of the Company’s 
named executive officers, which is required to occur no later than the Company’s 2029 annual meeting of shareholders. This disclosure 
is intended to satisfy the requirements of Item 5.07(d) of Form 8-K. 

The Company expects to incur restructuring costs of approximately $50 million to $70 million in fiscal year 2024 primarily 
related to ongoing actions that are expected to deliver continued margin improvement and efficiencies. Total cash costs for restructuring 
in fiscal year 2024 are expected to be approximately $110 million.
