Executive Compensation Practices

Our executive compensation program provides competitive packages that attract, motivate, reward and retain key talent
critical to achieving long-term financial and strategic objectives, and creating long-term stockholder value.
What We Do:

| Pay for Performance — A majority of the compensation opportunity for our NEOs is based on the achievement of key measures that drive value creation, including Adjusted Earnings Before Interest, Taxes, Depreciation, and Amortization (“Adjusted EBITDA”), segment adjusted operating margins, adjusted earnings per share growth, days sales outstanding ("DSO"), Return on Invested Capital (“ROIC”) improvement, and Relative Total Stockholder Return (“TSR”). |
| Rigorous Goal Setting — We undergo a detailed process of analyzing and reviewing a number of factors including, but not limited to our short and long-term financial plan; investor expectations; industry and peer performance; overall attainability; and impact on stockholder value creation. |
| Stockholder Engagement — We engage with stockholders throughout the year on proxy and governance matters, including direct outreach to stockholders that represent the ownership of more than 50% of our stock. |
| Stock Ownership Guidelines — We have stock ownership guidelines that require NEOs and non-employee directors to maintain a specific equity stake in the Company to align their interests with stockholders. The CEO ownership guideline is six times the base salary and the guideline for other NEOs is three times base salary. Non- employee directors must maintain ownership at a multiple of five times the annual retainer by the end of the fiscal year following the fifth anniversary of the director's initial appointment to the Board. |
| Independent Consultant — We utilize the services of an independent compensation consultant who does not provide any other services to the Company. |
| Risk Assessment — Our compensation consultant performs an independent risk assessment of compensation programs. |
| Clawback Policy — We have a clawback policy in compliance with Rule 10D-1 of the Securities Exchange Act of 1934 (“Exchange Act”) and NYSE Listing Standards, which requires us to recoup erroneously awarded incentive- based compensation paid to current and former officers in connection with an accounting restatement. |
| Market Study Analysis — We annually seek to understand labor market trends pertaining to amount and form of executive pay delivery through comprehensive competitive analyses. |
| Annual Say-on-Pay Vote — We have a policy to hold an advisory vote to approve the Company’s executive compensation on an annual basis. |
| Cash Severance Policy — We have a policy prohibiting cash severance benefits to exceed 2.99 times the sum of an executive officer’s base salary and annual target bonus without shareholder approval. |

AECOM | 6 | 2026 PROXY STATEMENT

Proxy Statement Summary
What We Don’t Do:

| Dividends and Dividend Equivalents on Unvested Awards — Our stock plan prohibits the payout of dividends or dividend equivalents on unvested long-term incentive equity awards unless and until the underlying award vests. |
| Stock Option Repricing — Our stock plan prohibits re-pricing underwater stock options or stock appreciation rights without stockholder approval. |
| Single Trigger Equity Acceleration — We do not maintain plans or agreements that provide for automatic “single trigger” equity acceleration or bonus payments in connection with a change in control (rather, any payment of benefit requires a qualifying termination of employment in connection with a change in control known as “double trigger”). |
| Tax Gross-Ups — We do not provide tax gross-ups to NEOs. |
| Hedging and Pledging — We prohibit hedging transactions involving AECOM common stock and do not allow trading in puts, calls, options or other similar transactions. In addition, we prohibit the pledging of AECOM common stock except in certain limited circumstances subject to Company approval and demonstration of the ability to repay the applicable loan without selling such securities. |

PROXY STATEMENT
ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD
MARCH 3, 2026
Introduction
This Proxy Statement is furnished in connection with the solicitation of proxies, on behalf of the Board of Directors of
AECOM, a Delaware corporation (“we,” “our,” the “Company” or “AECOM”), for use at our 2026 Annual Meeting of
Stockholders (“2026 Annual Meeting”) to be held on March 3, 2026, at 3:00 p.m. Central Time, or at any adjournment or
postponement thereof. At the 2026 Annual Meeting, you will be asked to consider and vote on the matters described in this
Proxy Statement and in the accompanying notice. The 2026 Annual Meeting will be held virtually online. You will be able to
attend the annual meeting, vote, and submit questions during the meeting by visiting www.meetnow.global/MJCU4RZ. Only
common stockholders of record at the close of business on January 9, 2026, which is the record date for the 2026 Annual
Meeting, are permitted to vote at the 2026 Annual Meeting and any adjournment or postponement thereof.
The Company’s Board of Directors (the “Board of Directors” or “Board”) is soliciting your vote to:
1.Elect each of the 8 director nominees named in this Proxy Statement to the Company’s Board of Directors to
serve until the Company’s 2027 Annual Meeting of Stockholders.
2.Ratify the selection of Ernst & Young LLP as our independent registered public accounting firm for fiscal year
2026.
3.Approve the Company’s executive compensation, on an advisory basis.
We utilize the U.S. Securities and Exchange Commission rule allowing companies to furnish proxy materials to their
stockholders over the Internet. We believe that this proxy process expedites stockholders’ receipt of proxy materials while
also lowering the costs and reducing the environmental impact of our annual meeting. On January 20, 2026, we began
mailing a Notice of Internet Availability of Proxy Materials (the “Notice”) to all stockholders of record as of January 9, 2026
and posted our proxy materials on the website referenced in the Notice. As more fully described in the Notice, all
stockholders may choose to access our proxy materials on the website referred to in the Notice or may request a printed set
of our proxy materials. In addition, the Notice and website provide information regarding how you may request proxy
materials in printed form by mail or electronically by email on an ongoing basis.

Annual Meeting Information
Annual Meeting Information

Proxies

You may vote your shares at the 2026 Annual Meeting or by proxy if you are a record holder. There are three ways to vote
by proxy: (1) on the Internet by following the instructions on the Notice or proxy card, (2) by telephone by calling
1-800-652-8683 and following the instructions on the Notice or proxy card or (3) by requesting a printed copy of the proxy
materials and signing, dating and mailing the enclosed proxy card to the address accompanying your proxy materials. If your
shares are held in the name of a bank, broker or another holder of record, you will receive instructions from the holder of
record. You must follow the instructions of the holder of record in order for your shares to be voted. Internet and telephone
voting will also be offered to stockholders owning shares through certain banks and brokers.
You may revoke your proxy at any time before it is exercised at the 2026 Annual Meeting by (1) giving our Corporate
Secretary written notice of revocation, (2) delivering to us a signed proxy card with a later date, (3) granting a subsequent
proxy through the Internet or telephone or (4) attending the 2026 Annual Meeting and voting. Written notices of revocation
and other communications with respect to the revocation of proxies should be addressed to AECOM, 13355 Noel Road,
Suite 400, Dallas, Texas 75240, Attention: Corporate Secretary.
All shares represented by valid proxies received and not revoked before they are exercised will be voted in the manner
specified in the proxy. If you submit a proxy but do not direct how to vote on each item, the persons named as proxies will
vote in favor of each of the proposals. Our Board is unaware of any matters other than those described in this Proxy
Statement that may be presented for action at our 2026 Annual Meeting. If other matters do properly come before our 2026
Annual Meeting, however, it is intended that shares represented by proxies will be voted in the discretion of the proxy
holders.
If you are a beneficial owner and hold your shares in the name of a bank, broker or another holder of record and do not
return the voting instruction card, the broker or another nominee may vote your shares on each matter at the 2026 Annual
Meeting for which he or she has the requisite discretionary authority. Under applicable rules, brokers have the discretion to
vote on routine matters, which include the ratification of the selection of the independent registered public accounting firm.
Brokers will not have the discretion to vote on any of the other proposals presented at the 2026 Annual Meeting.

Solicitation of Proxies

We will pay the entire cost of soliciting proxies. In addition to soliciting proxies by mail and by the Internet, we will request
banks, brokers and other record holders to send proxies and proxy materials to the beneficial owners of our common stock
and to secure their voting instructions, if necessary. We will reimburse current record holders for their reasonable expenses
in performing these tasks. We have agreed to pay Georgeson LLC $15,000 plus reasonable expenses, costs and
disbursements for various proxy solicitation services associated with the 2026 Annual Meeting. If necessary, we may use our
regular employees, who will not be specially compensated, to solicit proxies from stockholders, whether personally or by
telephone, letter or other means.

Record Date and Voting Rights

Our Board has fixed January 9, 2026 as the record date for determining the stockholders who are entitled to notice of, and to
vote at, our 2026 Annual Meeting. Only common stockholders of record at the close of business on the record date will
receive notice of, and be able to vote at, our 2026 Annual Meeting. As of the record date, there were 129,278,980 shares of
our common stock outstanding held by 1,302 record holders. A majority of the stock issued and outstanding and entitled to
vote must be present at our 2026 Annual Meeting, either in person or by proxy, in order for there to be a quorum at the
meeting. Each share of our outstanding common stock entitles its holder to one vote. Shares of our common stock with
respect to which the holders are present at our 2026 Annual Meeting but not voting, and shares for which we have received
proxies but with respect to which holders of the shares have abstained, will be counted as present at our 2026 Annual
Meeting for the purpose of determining whether a quorum exists. “Broker non-votes” will also be counted as present for the
purpose of determining whether a quorum exists. Broker non-votes are shares of common stock held by brokers or
nominees over which the broker or nominee lacks discretionary power to vote and for which the broker or nominee has not
received specific voting instructions from the beneficial owner.

AECOM | 11 | 2026 PROXY STATEMENT

Annual Meeting Information

Majority Voting; Director Resignation Policy

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

AECOM | 13 | 2026 PROXY STATEMENT

Proposal 1
Proposal 1
Election of Directors
We are nominating 8 directors for election to our Board, all of whom are current members of our Board that are standing for
re-election at the 2026 Annual Meeting. Directors elected at the 2026 Annual Meeting will serve until the 2027 Annual
Meeting of Stockholders and until their successors are duly elected and qualified. If a quorum is present at our 2026 Annual
Meeting, the directors will be elected by a majority of the votes cast, which means that the number of shares voted “for” a
director must exceed the number of shares voted “against” that director, with any director who is not elected by a majority of
the votes cast being expected to tender his or her resignation to the Nominating Committee. The Nominating Committee will
recommend to the Board whether to accept or reject the resignation offer, or whether other action should be taken. The
Board will act on the Nominating Committee’s recommendation within 90 days following certification of the election results.
Shares represented by proxies will be voted, if authority to do so is not withheld, for the election of each of the director
nominees named in this Proxy Statement. We currently have 8 directors on our Board. Proxies cannot be voted for a greater
number of persons than the number of nominees named. Each of the nominees has consented to serve as a director if
elected, and management has no reason to believe that any nominee will be unable or unwilling to serve if elected as a
director, except as set forth in the remainder of this paragraph. In the event that any nominee is unavailable for re-election
as a result of an unexpected occurrence, shares will be voted for the election of such substitute nominee as our Board may
propose.

Director Qualifications

The Board believes that its members should collectively possess a combination of the skills, professional experience and
diversity of backgrounds necessary to oversee the Company’s business. The Nominating Committee is responsible for
developing and recommending Board membership criteria to the full Board for approval. The criteria, which are set forth in
the Company’s Corporate Governance Guidelines, include the highest professional and personal ethics and values,
commitment to enhancing stockholder value with sufficient time to effectively carry out his or her duties and business
acumen. In considering director candidates, the Nominating Committee looks for business experience and skills, judgment,
integrity, an understanding of such areas as finance, marketing, regulation and public policy and the absence of potential
conflicts with the Company’s interests. In particular, the Nominating Committee seeks candidates that have skills/experience
in the following areas, each of which it is views as particularly important: senior leadership experience, industry experience,
public company experience, financial expertise, government/regulatory expertise and international expertise. The
Nominating Committee believes that it is essential that Board members represent diverse viewpoints and backgrounds.
The Nominating Committee periodically reviews the appropriate skills and characteristics required of Board members in the
context of the current composition of the Board, the operating requirements of the Company and the long-term interests of
the Company’s stockholders. In conducting this assessment, the Nominating Committee considers diversity, skills and such
other factors as it deems appropriate to maintain a balance of knowledge, experience and capabilities. This periodic
assessment enables the Board to update the skills and experience it seeks in the Board, as a whole and in individual
directors, as the Company’s needs evolve over time. From time to time, while identifying director candidates, the Nominating
Committee may establish specific skills and experience that it believes the Company should seek to constitute a balanced
and effective Board.
Further, the Company’s Corporate Governance Guidelines provide that the Board should be comprised of individuals with
diverse backgrounds, experiences and perspectives.

Proposal 2
Ratification of Selection of Independent Registered
Public Accounting Firm
The Audit Committee of our Board has retained Ernst & Young LLP to serve as our independent registered public accounting
firm for the fiscal year ending September 30, 2026. Ernst & Young LLP has served as the Company’s independent registered
public accounting firm since 1990. A representative of Ernst & Young LLP is expected to be present at the 2026 Annual
Meeting, will have an opportunity to make a statement if the representative so desires, and will be available to respond to
appropriate questions.

Reasons for the Proposal

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

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

As with previous years, the Audit Committee undertook a review of Ernst & Young LLP in determining whether to select
Ernst & Young LLP as the Company’s independent registered public accounting firm for fiscal year 2026 and to recommend
ratification of its selection to the Company’s stockholders. In that review, the Audit Committee considered a number of
factors including:
•continued independence of Ernst & Young LLP;
•length of time Ernst & Young LLP has been engaged by the Company;
•senior management’s assessment of Ernst & Young LLP’s performance;
•audit and non-audit fees;
•capacity to appropriately staff the audit;
•geographic and subject matter coverage;
•lead audit engagement partner performance;
•overall performance;
•qualifications and quality control procedures; and
•whether retaining Ernst & Young LLP is in the best interests of the Company and its stockholders.
Based upon this review, the Audit Committee believes that Ernst & Young LLP is independent and that it is in the best
interests of the Company and our stockholders to retain Ernst & Young LLP to serve as our independent registered public
accounting firm for fiscal year 2026.
In accordance with the Sarbanes-Oxley Act and the related SEC rules, the Audit Committee limits the number of consecutive
years an individual partner may serve as the lead audit engagement partner to the Company. The maximum number of
consecutive years of service in that capacity is five years. The current lead audit engagement partner is in his second year in
that role.

Vote Required and Recommendation of the Board of Directors

The ratification of our independent registered public accounting firm requires the affirmative vote of the holders of a majority

Meeting. Abstentions will be counted as present and will have the effect of a vote against the proposal. Brokers have
discretion to vote on the ratification of our independent registered public accounting firm and, as such, no votes on this
proposal will be considered broker non-votes.

Proposal 3
Advisory Resolution to Approve Executive Compensation
In accordance with Section 14A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we are asking
our stockholders to approve, on an advisory basis, AECOM’s executive compensation as reported in this Proxy Statement.
At AECOM, executive compensation plans are driven by both short- and long-term financial performance metrics that are
designed to incentivize our Named Executive Officers (NEOs) to maximize long-term stockholder value creation. As such,
based on direct stockholder feedback, AECOM’s executives are incentivized via an annual cash bonus plan and certain
long-term equity awards that include without limitation the following performance metrics: adjusted earnings per share,
return on invested capital, and relative total stockholder return.
We urge stockholders to read the “Compensation Discussion and Analysis” section in this Proxy Statement, which describes
in more detail how our executive compensation policies and procedures operate and are designed to achieve our
compensation objectives, as well as the “Summary Compensation Table” and related compensation tables and narrative,
which provide detailed information on the compensation of our NEOs. The Compensation and Organization Committee
(“Compensation Committee”) and the Board believe that the policies, procedures and programs articulated in the
“Compensation Discussion and Analysis” are effective in achieving our goals and that the compensation of our NEOs
reported in this Proxy Statement has supported and contributed to the Company’s success.
We are asking stockholders to approve the following advisory resolution at the 2026 Annual Meeting:
RESOLVED, that the stockholders of AECOM approve, on an advisory basis, the compensation of the Company’s Named
Executive Officers, disclosed pursuant to Item 402 of Regulation S-K, set forth in the Compensation Discussion and
Analysis, the Summary Compensation Table and the related compensation tables and narrative in the Proxy Statement for
the Company’s 2026 Annual Meeting of Stockholders.
This advisory resolution, commonly referred to as a “Say-on-Pay” resolution, is nonbinding on the Company, the Board and
the Compensation Committee and will not be construed as overruling a decision by, nor creating nor implying any additional
fiduciary duty for the Company, the Board or the Compensation Committee. However, the Board and the Compensation
Committee will review and consider the voting results on this proposal when evaluating our executive compensation
program.

Vote Required and Recommendation of the Board of Directors

The affirmative vote of the holders of a majority of the shares of common stock present or represented by proxy and entitled
to vote at the 2026 Annual Meeting is required to approve the advisory resolution on the Company’s executive
compensation. Abstentions will be counted as present and will have the effect of a vote against the proposal. Broker non-
votes will not be counted as participating in the voting on the proposal and will therefore have no effect on the outcome of
the vote on the proposal.

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

Board Meetings

During our fiscal year ended September 30, 2025, our Board met five times, the Audit Committee met five times, the
Compensation Committee met three times and the Nominating Committee met three times. Each incumbent director
attended 100% of (1) the total number of meetings of our Board and (2) the total number of meetings held by all standing
committees of the Board on which he or she served during fiscal year 2025.

Director Independence

Seven of the eight director nominees are independent directors as defined in accordance with the listing standards of the
NYSE. These standards provide that a director is independent only if our Board affirmatively determines that the director has
no direct or indirect material relationship with the Company. They also specify various relationships that preclude a
determination of director independence. Material relationships may include commercial, industrial, consulting, legal,
accounting, charitable, family and other business, professional and personal relationships.
Applying these standards, our Board, upon the recommendation of our Nominating Committee, annually reviews the
independence of our directors. In its most recent review, our Board considered, among other things, the employment
relationships between the Company and our directors and their families; the other specific relationships that would preclude
a determination of independence under the NYSE independence rules; any affiliation of the Company’s directors and their
families with the Company’s independent registered public accounting firm, compensation consultants, legal counsel and
other consultants and advisors; any transactions with directors and members of their families that would require disclosure in
this Proxy Statement under U.S. Securities and Exchange Commission (“SEC”) rules regarding related party transactions;
and the amount of our contributions to non-profit organizations of which some of our directors or members of their families
are associated.
The Board determined that the following director nominees are independent as determined by the standards of the NYSE:
Bradley W. Buss, Derek J. Kerr, Kristy Pipes, Douglas W. Stotlar, Daniel R. Tishman, Sander van ’t Noordende and General
Janet C. Wolfenbarger.

Board Leadership Structure

Mr. Rudd serves as the combined Chairman and CEO and Mr. Stotlar serves in the role of Lead Independent Director. As
Lead Independent Director, Mr. Stotlar, along with the other independent directors, brings experience, oversight and
expertise from outside the Company and industry, while our Chairman and CEO, Mr. Rudd, brings Company and industry-
specific experience and expertise.
As Lead Independent Director, Mr. Stotlar has the following powers and duties: (i) chairing the executive sessions of
independent directors; (ii) serving as liaison between the Chairman and the independent directors; (iii) approving information
sent to the Board; (iv) approving meeting agendas for the Board; (v) approving meeting schedules to assure that there is
sufficient time for discussion of all agenda items; (vi) calling meetings of the independent directors; and (vii) if requested by
major shareholders, ensuring that he is available for consultation and director communication.
The Board has been, and continues to be, a proponent of Board independence. The Company’s corporate governance
structures and practices provide for a strong, independent Board and include several independent oversight mechanisms,
including only independent directors serving as committee chairs and the directors’ and committees’ ability to engage
independent consultants and advisors. The Audit, Compensation and Nominating Committees are composed entirely of
independent directors.

AECOM | 25 | 2026 PROXY STATEMENT

Corporate Governance

Executive Sessions

Executive sessions of non-employee directors are included on the agenda for every regularly scheduled Board and committee
meeting and, during fiscal year 2025, executive sessions were held at each regularly scheduled Board and committee
meeting. Executive sessions are currently chaired by the Lead Independent Director during Board meetings, and by the
respective Committee Chair during committee meetings. Our Corporate Governance Guidelines provide that at any time in
which the Board has a Lead Independent Director, the Lead Independent Director will chair executive sessions and will consult
with the Chairman and CEO on agendas for Board meetings and other matters pertinent to the Company and the Board.

Board’s Role in Risk Oversight

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

•Oversee lobbying and political

We believe the division of risk management responsibilities described above provides an effective framework for evaluating
and addressing the risks facing the Company, and that our Board leadership structure supports this approach because it
allows our independent directors, through the independent committee chairs, to exercise effective oversight of the actions of
management.

Risk Assessment of Compensation Policies and Practices

In fiscal year 2025, the Compensation Committee’s independent consultant, Exequity LLP, conducted a risk assessment of
the Company’s compensation policies and practices as they apply to all employees, including executive officers. Exequity
LLP reviewed the design features and performance metrics of our cash and stock-based incentive programs, along with the

AECOM | 26 | 2026 PROXY STATEMENT

Corporate Governance
approval mechanisms associated with each, to determine whether any of these policies and practices could create risks that
are reasonably likely to have a material adverse effect on the Company.
As part of the review, several factors were noted that reduce the likelihood of excessive risk-taking:
•Our compensation mix is balanced among fixed components such as salary and benefits, annual incentive
payments and long-term incentives, including Performance Earning Program (“PEP”) awards and restricted stock
units (“RSU”) granted under our stockholder-approved 2020 Stock Incentive Plan, which typically vest or are earned
over three years.
•The Compensation Committee has ultimate authority to determine, and reduce, if appropriate and consistent with
applicable arrangements, compensation provided to our executive officers, including each of the NEOs.
•The Compensation Committee, under its charter, has the authority to retain any advisor it deems necessary to fulfil
its obligations and has engaged Exequity LLP as its independent consultant. Exequity performs services for the
Compensation Committee as described in the “Compensation Discussion and Analysis” section of this Proxy
Statement.
•Our annual incentive programs for employees are funded in the aggregate based on the results of key financial
metrics. Individual payouts are based on a combination of financial metrics as well as qualitative factors.
•Our long-term equity incentive awards, including PEP awards and restricted stock units granted under our
stockholder-approved 2020 Stock Incentive Plan, are all approved by either the Compensation Committee for our
executive officers or by our Chief Executive Officer for non-executive officers.
•Our NEOs are subject to stock ownership guidelines, our insider trading policy and our updated clawback policy.
Based on this assessment, the Company concluded that its compensation policies and practices do not create risks that are
reasonably likely to have a material adverse effect on the Company.

Committees of the Board of Directors

The Board has three standing committees: the Audit Committee, the Compensation Committee, and the Nominating
Committee. In accordance with NYSE regulations, each member of the Audit Committee, the Compensation Committee, and
the Nominating Committee has been determined by our Board to be “independent.” The committees operate under written

10A-3(b)(1) of the rules of the U.S. Securities and Exchange Commission and the regulations of the NYSE, appoints the
Company’s independent auditors, reviews the results and scope of the audit of our financial statements as well as other
services provided by our independent auditors, reviews and approves audit fees and all non-audit services as well as
reviews and evaluates our audit and control functions, including our internal audit function. Our Board has determined that
Ms. Pipes, Chair of the Audit Committee, qualifies as an “audit committee financial expert” as defined by the rules under the
Exchange Act. The “Report of the Audit Committee of the Board of Directors” is included in this Proxy Statement. Our Audit
Committee held five meetings during fiscal year 2025.
Compensation and Organization Committee. The Compensation Committee, which is composed solely of independent
directors as defined under the regulations of the NYSE, oversees our compensation plans. Such oversight includes
decisions regarding executive management salaries, incentive compensation and long-term compensation plans, as well as
Company-wide equity plans for our employees. Grants of equity awards by the Compensation Committee under our
compensation plans are approved solely by directors who are “Non-Employee Directors” within the meaning of Rule 16b-3
under the Exchange Act. This committee also reviews the Board’s compensation plan for non-employee directors and
determines whether independent compensation consultants should be utilized. For further information regarding the
Compensation Committee’s processes and procedures for determining executive and non-employee director compensation,
see the “Compensation Discussion and Analysis” section of this Proxy Statement. The “Report of the Compensation and
Organization Committee of the Board of Directors” is included in this Proxy Statement. Our Compensation Committee held
three meetings during fiscal year 2025.
Nominating and Governance Committee. The Nominating Committee is composed solely of independent directors as
defined under the regulations of the NYSE and is responsible for recruiting and retaining qualified persons to serve on our
Board, including recommending such individuals to the Board for nomination for election as directors; for evaluating director
independence; and for oversight of our compliance activities. The Nominating Committee also considers written suggestions
from stockholders, including potential nominees for election, and oversees other governance programs such as the
Company’s Corporate Governance Guidelines. This committee also conducts performance evaluations for directors being
elected at each annual meeting of stockholders, and engages in succession planning for the Board and key leadership roles
on the Board and its committees. Our Nominating Committee held three meetings during fiscal year 2025.

Corporate Governance Guidelines

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

Codes of Conduct and Ethics

We have adopted a Code of Conduct that describes the professional, legal, ethical, financial and social responsibilities of all
of our directors, officers and employees. We require all of our directors, officers and employees to read and acknowledge
the Code of Conduct, and we provide regular compliance training. Our directors, officers and employees are also
encouraged to report suspected violations of the Code of Conduct through various means, including a toll-free hotline
available 24 hours, 7 days a week in multiple languages, and they may do so anonymously. We do not tolerate acts of
retaliation against anyone who makes an honest and sincere report of a possible violation of law or of our Code of Conduct
or policies, or who participates in an investigation of possible wrongdoing. Many countries have enacted legislation to protect
those who report misconduct, and we enforce any applicable protections afforded by such laws.
If we make substantive amendments to the Code of Conduct or grant any waiver, including any implicit waiver, to our
principal executive, financial or accounting officer or persons performing similar functions or any director, we will disclose the
nature of such amendment or waiver in accordance with applicable rules and regulations. In addition, we have a separate
Code of Ethics for Senior Financial Officers that specifies the required standards of conduct for employees with financial
reporting responsibilities. We also have an Anti-corruption Policy that provides specific guidance to help ensure that lawful
and ethical business practices are followed while our employees conduct business anywhere in the world. Many of these
policies are available for viewing on the “Ethics and Compliance” section of our website at www.aecom.com and in print to
any stockholder that requests it. Any such request should be addressed to AECOM, 13355 Noel Road, Suite 400, Dallas,

Director Nominations, Board Refresh and Succession Planning

The Nominating Committee is charged with identifying, reviewing and recommending to the Board qualified individuals to
become directors and regularly assessing the size and composition of the Board and recommending any changes to the
Board. The Nominating Committee also engages in succession planning for the Board and key leadership roles on the
Board and its committees.
The Nominating Committee reviews the appropriate skills and characteristics required of Board members in the context of
the current composition of the Board, the operating requirements of the Company and the long-term interests of the
Company’s stockholders. In conducting this assessment, the Nominating Committee considers diversity, skills and such
other factors as it deems appropriate to maintain a balance of knowledge, experience and capabilities. This periodic
assessment enables the Board to update the skills and experience it seeks in the Board, as a whole and in individual
directors, as the Company’s needs evolve over time. From time to time, while identifying director candidates, the Nominating
Committee may establish specific skills and experience that it believes the Company should seek to constitute a balanced
and effective Board.

It is our belief that members of the Board should have the highest professional and personal ethics and values. We believe
that the Board should be comprised of individuals who are committed to enhancing stockholder value with sufficient time to
effectively carry out their duties. While all directors should possess business acumen, the Board endeavors to include an
array of targeted skills and experience in its overall composition. Criteria that the Nominating Committee looks for in director
candidates include business experience and skills, judgment, integrity, an understanding of such areas as finance,
marketing, regulation, cybersecurity and technology, end markets and public policy and the absence of potential conflicts
with the Company’s interests. In particular, the Nominating Committee seeks candidates that have the following key skills
and experience, each of which it views as particularly important:
•senior leadership experience;
•industry experience;
•public company experience;
•financial expertise;
•government/regulatory expertise; and
•international expertise.
The Nominating Committee believes that it is essential that Board members represent diverse viewpoints and backgrounds.
In identifying and selecting individuals, the Board and the Nominating Committee consider diversity, skills, and such other
factors as they deem appropriate to maintain a balance of knowledge, experience and capability. Diversity is an important
consideration in the director nomination process because the Board believes that people of different experiences can
contribute useful perspectives while collaborating effectively to further the Company’s objectives.

AECOM | 29 | 2026 PROXY STATEMENT

Corporate Governance
Our Nominating Committee will consider stockholder nominations for directors. The Nominating Committee evaluates any
such nominees that are properly submitted using the same criteria it otherwise employs, as described in our Corporate
Governance Guidelines. Any recommendation submitted by a stockholder must include the same information concerning the
potential candidate as is required when a stockholder wishes to nominate a candidate directly. In addition, any such
recommendation must be received in the same time frame as is required by our Bylaws when a stockholder wishes to
nominate a candidate directly. To be timely, the notice must be received by the close of business no fewer than 90 and no
more than 120 days prior to the date of the first anniversary of the preceding year’s annual meeting of stockholders.
However, in the event that the date of the annual meeting is advanced more than 30 days prior to such anniversary date or
delayed more than 30 days after such anniversary date, or no annual meeting was held in the preceding year, notice by the
stockholder to be timely must be received no more than 120 days prior to the date of the annual meeting and not less than
the later of the close of business (a) 90 days prior to the date of the annual meeting and (b) on the 10th day following the
day on which public announcement of the date of such meeting was first made by the Company. In no event shall an
adjournment, recess or postponement of any annual meeting commence a new time period (or extend any time period) for
the giving of a stockholder notice.
To be in proper form, the notice must, as to each person whom the stockholder proposes to nominate for election or re-
election as a director, set forth all information concerning such person as would be required in a proxy statement soliciting
proxies for the election of directors in a contested election pursuant to Section 14 of the Exchange Act and all written and
signed representations and all completed and signed questionnaires required pursuant to our Bylaws. In addition, as to the
stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination is being made, the notice
must also state the name and address, as they appear on the Company’s books, of such stockholder and such beneficial
owner and the class or series and number of shares of the Company that are owned of record and beneficially by such
stockholder and such beneficial owner.
As to the stockholder giving the notice, or if the notice is on behalf of a beneficial owner on whose behalf the nomination is
being made, as to such beneficial owner, and if such beneficial owner is an entity, as to each control person of such entity,
the notice must state the class or series and number of shares of the Company that are owned of record and beneficially by
such stockholder or beneficial owner and by any control person, a description of any agreement, arrangement or
understanding with respect to the nomination between such stockholder or beneficial owner and any other person and by
any control person, including, without limitation, any agreements that would be required to be disclosed pursuant to Item 5 or
Item 6 of Schedule 13D (regardless of whether the requirement to file a Schedule 13D is applicable) of the Exchange Act,
and a description of any agreement, arrangement or understanding (including, without limitation, any derivative or short
positions, profit interests, options, hedging transactions, and borrowed or loaned shares) that has been entered into as of
the date of the stockholder’s notice by, or on behalf of, such stockholder, beneficial owner or control person, the effect or
intent of which is to mitigate loss, manage risk or benefit from changes in the share price of any class or series of the
Company’s capital stock, or maintain, increase or decrease the voting power of the stockholder, beneficial owner or control
person with respect to shares of stock of the Company. Stockholders who wish to nominate candidates for director must do
so pursuant to these procedures.
In order to encourage Board refreshment and facilitate succession planning, in November 2023 the Board updated its
Corporate Governance Guidelines to establish a maximum twelve-year term of service requirement for new directors and a
mandatory retirement age of 72 (75 for current directors).

Board Self-Assessment

The Nominating Committee facilitates an annual assessment of the performance of the Board and its committees and
coordinates reports of the annual results to the full Board for discussions. The Nominating Committee also recommends
changes to improve the Board and its committees. In 2025, the Nominating Committee engaged an outside law firm to
obtain input from each director on the performance of the Board and its committees.

Director Attendance at Annual Meetings

AECOM’s policy is for directors to attend our annual meetings of stockholders unless there are extenuating circumstances.
All directors at the time of the meeting attended the 2025 Annual Meeting.

Director Compensation

Information regarding the compensation of our non-employee directors is discussed below in “Directors' Compensation for
Fiscal Year 2025.”

Director Retirement Policy

Our Corporate Governance Guidelines provide that directors are required to retire from the Board at the end of the term of
service during which they turn 72 years of age (or 75 for current directors).

Related Party Transaction Policy

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

Certain Relationships and Related Transactions

In fiscal year 2025, the Company did not have any related party transactions that meet the disclosure requirements of Item
404 of Regulation S-K.

Insider Trading Policy

We have an Insider Trading Policy that governs the purchase, sale and other disposition of AECOM securities by our
directors, officers, employees and certain consultants. We believe that our Insider Trading Policy is reasonably designed to
promote compliance with insider trading laws, rules and regulations and the exchange listing standards applicable to us.
Among other restrictions, our Insider Trading Policy prohibits directors, officers, employees and consultants from trading in
our securities while in possession of material, non-public information. The foregoing summary of our Insider Trading Policy
does not purport to be complete and is qualified by reference to the full text of our Insider Trading Policy, a copy of which
can be found as an exhibit to our 2025 Form 10-K.

Political Contributions and Lobbying

Our responsible participation in the U.S. political process is important to our success and the protection of stockholder value.
Our Political Engagement Policy is available on the “Government Relations” area of the “About Us” section on our website at
www.aecom.com. We update and publish our Political Engagement Policy annually, along with supporting exhibits detailing
our political expenditures. That annual disclosure includes, but is not limited to, the following information:
•Federal, state and local lobbying expenditures;
•Amounts and recipients of any direct political contributions made by us in the United States (if any such
expenditures are made);
•Amounts and recipients of any federal, state or local political contributions made by the AECOM PAC in the United
States (if any such expenditures are made); and
•Amounts and recipients of payments made in connection with our most significant memberships in trade
associations and industry groups.
In addition, we file quarterly a publicly available federal Lobbying Disclosure Act Report, providing information on activities
associated with influencing legislation through communications with any Member of Congress, congressional staffer, or with
any covered federal executive branch official. The report also provides disclosure on expenditures for the quarter, describes
the specific pieces of federal legislation that were the topic of communications, and identifies the individuals who lobbied on
behalf of AECOM. AECOM files similar periodic reports with state agencies where required reflecting state lobbying activities
which are also publicly available.

Stock Ownership Guidelines for Non-Employee Directors

Non-employee directors are subject to stock ownership guidelines, which are intended to align their interests with those of
our stockholders. Under the guidelines, our non-employee directors must maintain ownership of AECOM stock at a multiple
of five times the annual retainer by the end of the fiscal year following the fifth anniversary of the director’s initial
appointment to the Board. The minimum number of shares guideline is updated annually based on the current cash retainer
($100,000) and the 12-month trailing average AECOM stock price. Shares owned directly or indirectly, the value of vested
but unexercised stock options and unvested restricted stock are counted toward the guidelines. The table below outlines the
ownership of our non-employee directors as of October 1, 2025. All current non-employee directors already meet or are
expected to meet guidelines within the five (5) year transition period.

Compensation Discussion and Analysis
•Segment Adjusted Operating Margin on Net Service Revenue (NSR) increased by 70 basis points to 16.5%, which
exceeded our guidance, set a new full year record and included a 17.1% margin in the second half of the year that
achieved our 17% long-term target more than a year ahead of prior expectations.

both our initial and thrice-increased guidance, and set a record high.
•Adjusted Earnings per Share (“EPS”) increased by 16% over the prior year to $5.26, which exceeded the mid-point of
the ranges in both our initial and thrice-increased guidance.
•Free Cash Flow of $685 million for the full year was materially consistent with our expectations.

Executive Pay Philosophy

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

Pillars of our Executive Pay Program

Market Competitive: Assess NEO target pay levels against market compensation data prepared by our independent
compensation consultant
Pay Supports Strategy: Select incentive metrics that drive achievement of long-term financial and strategic objectives
Performance-Based: Impose performance conditions on the majority of the compensation that may be paid to our NEOs
Rigorous Goal Setting: Require performance that meets investor guidance and/or outperforms our industry for target
payout on incentive-based compensation
Stockholder Alignment: Align a significant portion of NEO total compensation opportunity with our stockholders through
long-term equity awards, the majority of which must be earned by achieving pre-established, multi-year performance
standards

Compensation Process

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

Management |  | Independent Consultant |  | Compensation Committee
•Engages with investors and reviews feedback on NEO compensation and compensation program design •Reviews design following a rigorous financial planning process •CEO conducts performance reviews for other NEOs and recommends compensation to the Compensation Committee |  | •Provides the committee with market data with respect to NEO benchmark pay levels and input on executive compensation plans and program design |  | •Engages with investors and reviews feedback on NEO compensation and compensation program •Evaluates the CEO’s performance •Reviews and approves all NEO compensation and compensation programs

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

AECOM | 38 | 2026 PROXY STATEMENT

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

Role of the Compensation Committee

–Reviews the Company’s financial, strategic and operational metrics and goals, compensation peer group and
approves the performance objectives of the CEO and other executive officers.
–Approves design changes to the executive compensation program, as applicable.
–Reviews full year Company financial and strategic performance to understand accomplishments relative to
established objectives.
–Evaluates the CEO’s performance in light of the review of Company performance.
–Discusses with the CEO his evaluation of the performance of each of the other executive officers relative to their
individual performance objectives.
–Determines compensation amounts for the CEO and each of the other executive officers, taking into account:
•Prior year’s compensation;
•Performance assessments;
•Market considerations;
•Internal equity;
•Individual performance and retention considerations;
•Input from the Compensation Committee’s independent compensation consultant; and
•For the other NEOs, the CEO’s recommendations.
–Reviews and approves the grants and payouts of long-term incentive equity awards, including certification of the
financial results that support awards made under the annual and long-term incentive programs.
With respect to individual long-term incentive equity awards, the Compensation Committee considers individual
performance, market data, including compensation for comparable positions at peer companies, and the strategic
importance of the NEO’s position to determine a dollar denominated long-term incentive equity value to be awarded to each
NEO. The dollar value awarded by the Compensation Committee to each NEO is then converted into a specific number of
units, based on the fair market value of AECOM common stock on the date of grant.

Compensation and Organization Committee’s Independent Compensation Consultant

The Compensation Committee has the authority to retain the services of outside consultants to assist it in performing its
responsibilities. The Compensation Committee engaged the services of the consulting firm Exequity LLP. During fiscal year
2025, the consultant provided data on the compensation and relative performance of compensation peer group companies
as well as general industry data to the Compensation Committee, made presentations on regulatory and legislative matters
affecting executive compensation, provided advice on the degree to which compensation arrangements are consistent with
market practices, and consulted on other executive compensation matters as needed. Exequity LLP does not provide any
services to the Company other than advising the Compensation Committee on executive and non-employee director
compensation matters.
The Compensation Committee has assessed the independence of Exequity LLP, considering the following six factors and
other factors that it deemed relevant: (1) other services provided to the Company by Exequity LLP, (2) the amount of fees
paid by the Company to Exequity LLP as a percentage of Exequity LLP’s total revenue, (3) the policies or procedures
maintained by Exequity LLP that are designed to prevent conflicts of interest, (4) any business or personal relationships
between the individual employees of Exequity LLP involved in the engagement and a member of the Compensation

AECOM | 39 | 2026 PROXY STATEMENT

Compensation Governance, Process and Decisions
Committee, (5) any AECOM stock owned by Exequity LLP’s employees involved in the engagement and (6) any business or
personal relationships between our executive officers and Exequity LLP or the employees of Exequity LLP involved in the
engagement. Following such assessment, the Compensation Committee concluded that Exequity LLP is independent and
that Exequity LLP’s work raises no conflicts of interest.

Assessing Competitive Practice

As part of its due diligence when making compensation decisions, the Compensation Committee examines pay data for a
group of comparable companies to stay current with market pay practices and trends and to understand the competitiveness
of the Company’s total compensation and its components of pay. The Compensation Committee uses the compensation
peer group and market survey data for informational purposes. The Company does not target a specific percentile or make
significant pay decisions based on market data alone. The Compensation Committee considers Company performance as
well as the level of responsibility, experience and tenure of the individual and performance in the role.
Fiscal Year 2025 Compensation Peer Group
The Compensation Committee, when developing the compensation peer group (the “Compensation Peer Group”), identified
the Company's competitors for talent and considered other various measures of size, scope and complexity, with a focus on
revenue and enterprise value. For fiscal year 2025, the Compensation Committee refined the Company's compensation
peer group to better align with our on-going transformation into a professional services business.

program. In fiscal year 2025, we directly engaged with stockholders who collectively own greater than 50% of our
outstanding shares on matters relating to the Company's strategy, performance and governance. Stockholders affirmed their
support for the Company’s compensation philosophy, chosen metrics, and resulting pay-for-performance alignment, as
evidenced by last year’s high level of support for the Company’s directors and executive compensation program, and
continued to emphasize an expectation for best-in-class governance and pay-for-performance alignment.

by the Board.

AECOM | 41 | 2026 PROXY STATEMENT

Elements of Our Named Executive Officer Compensation

Metric |  |  | Why Selected |
Days Sales Outstanding |  |  | Days Sales Outstanding ("DSO") incentivizes the timely conversion of billings to cash flow, which enables the execution of our returns-based capital allocation policy to compound value for stockholders. |
Adjusted EBITDA |  |  | Adjusted EBITDA incentivizes achievement of our annual financial plan, which includes delivering high-value organic revenue growth, margin expansion, and disciplined investments in growth initiatives, employee development programs, and innovation. |
Segment Adjusted Operating Margin on NSR |  |  | Segment Adjusted Operating Margin on Net Service Revenue (NSR)% focuses on underlying operational performance, including executing our strategy, which emphasizes profitable growth, and investing through our margins to deliver for today and deliver more in the future. |
Key Performance Indicator (“KPI”) Assessment |  |  | KPI Assessment encourages focus on the achievement of the Company’s non- financial strategic objectives including sustainability-related goals. These KPIs are developed for each NEO and, in the instance of our CEO, include such non-financial strategic objectives as: •Total recordable incident rate of no greater than 0.11, which would continue to lead the industry •Voluntary attrition of high-performers of less than 10%, which would exceed benchmark levels •Company-wide safety, digital and ethics training completion of 100%, which would further extend our track record of consistently achieving 100% compliance on mandatory training •Employee satisfaction as reflected by the percentage of employees that would recommend AECOM as a great place to work as indicated in the Company’s bi-annual all-employee survey of at least 70%, which would continue to significantly exceed industry benchmark levels |

Annual Incentive Calculations

For fiscal year 2025, each of the NEOs was measured on the following financial metrics and performance results:

Financial Metrics* | Weighting Percentage | Threshold Amount (0% Payout) | Target Amount (100% Payout) | Maximum Amount (200% Payout) | Actual Amount | Earned Percentage**
Days Sales Outstanding | 20% | 77 days | 73 days | 69 days | 73.8 days | 16.2%
Adjusted EBITDA | 35% | $1,071.0 | $1,190.0 | $1,309.0 | $1,202.6 | 38.7%
Segment Adjusted Operating Margin on NSR | 25% | 14.4% | 16.0% | 17.6% | 16.5% | 32.1%
KPIs | 20% | Varies by Individual NEO | See below

*Numbers in millions for Adjusted EBITDA. See Annex A, Reconciliation of Non-GAAP Items.
**Linear interpolation is applied for outcomes between those shown in the illustration.
Additionally, each NEO received KPI assessment results based on their individual contributions to the Company’s strategic
plan. Total earned percentage payouts were determined based on the combined earned percentages from both the financial
metrics and KPI results as follows:

Key Performance Indicator Assessment
With respect to each of our NEOs, the KPI assessment focuses on the individual’s contributions to objectives that are part of
the Company’s strategic plan. For fiscal year 2025, the following details the KPI assessment goals and actual results
achieved by our CEO; the KPIs for all other NEOs are a subset of our CEO’s.

NEO | Achievements |
Troy Rudd | •Further Extended Track Record of Outperforming on All Key Financial Objectives: We delivered new records for net service revenue, margins and earnings, highlighted by the achievement of a 17%+ segment adjusted operating margin in the second half of the year, which was more than a year head of prior expectations. As a result, we delivered 10% adjusted EBITDA growth and 16% adjusted EPS growth for the full year, both of which exceeded the mid-points of both our original and increased guidance. •'Winning What Matters', Positioned the Company for Continued Success: Our win rate remained at a record high, driven by an 80% win rate on our largest and most strategically valuable pursuits. In addition, our backlog and pipeline of opportunities remain at a record high, providing for unprecedented visibility. •Continued to Invest to Expand Our Capabilities: Leveraging the capacity created by our record margins, we continued to invest in our business, our professionals and our capabilities to further enhance our offering for clients. This included growing the Advisory global business line with key senior executive hires that have supported accelerating growth in this business in fiscal year 2025. We also continued to invest to revolutionize what we deliver and how we deliver it through AI, including through Oscar, our proprietary LLM tool, and AI for Engineering, our proprietary AI agent for complex design tasks. Through these capabilities, we are expanding the operating leverage in the business and transforming the value we deliver to clients, which extends our competitive advantage. •Continued Record Levels of Employee Engagement: Reflecting strong execution on our Think and Act Globally strategy, including further investments in our Employee Value Proposition that continue to strengthen technical and professional development opportunities for our professionals, employee engagement remains at record levels. As indicated by our most recent employee survey, 78% of employees would recommend AECOM as a great place to work, significantly exceeding professional services benchmarks. In addition, safety performance is a key leading indicator of success, and our total recordable incident rate (TRIR) of 0.08 continues to be substantially ahead of peers and broader industry benchmarks. •Maximized Stockholder Value: Reflecting strong financial performance and a strong balance sheet, we returned nearly $500 million to stockholders through share repurchases and dividends. Our balance sheet remains a competitive advantage with 0.8x net leverage and more than 70% of our debt fixed, swapped to fixed, or capped over the next several years and no near-term bond maturities. |

Elements of Our Named Executive Officer Compensation

Long-Term Incentives

Long-term incentive equity awards reward the creation of long-term stockholder value and achievement of key metrics over
a longer-term period, aligning our NEOs’ interests with those of our stockholders by linking the value of our NEOs’
compensation to AECOM’s stock price. The PEP awards are subject to performance metrics that drive the successful
execution of our long-term strategy to build sustainable profitable growth and stockholder value, and both the PEP awards
and RSU awards serve as a retention tool for our NEOs with 3-year continued service vesting requirements.
Long-Term Equity Incentive Award
As part of its review of fiscal year 2025 performance, the Compensation Committee analyzed the role and responsibilities of
each NEO, including their past and current performance history, and prevailing market practices with respect to our
Compensation Peer Group and across industries. Based on these factors (as well as taking into consideration the
Compensation Committee’s collective experience regarding appropriate annual equity grant levels), the Compensation
Committee approved the following equity awards in fiscal year 2025:

NEOs | 2024 ($) | 2025 ($) | Percent Change (%) |
Troy Rudd | 9,500,000 | 11,000,000 | 15.8 |
Gaurav Kapoor | 2,900,000 | 3,200,000 | 10.3 |
Lara Poloni | 3,100,000 | 3,500,000 | 12.9 |
David Gan | 1,400,000 | 1,500,000 | 7.1 |

For fiscal year 2025, the long-term incentive equity award received by each NEO was comprised of the following:

Type | Weighting Percentage | Performance Measures and Vesting Requirements
PEP | 60% | Metrics: –1/3rd to vest based on 3-year Relative TSR –1/3rd to vest based on 3-year average ROIC(1) achievements –1/3rd to vest based on 1-year, 2-year average, and 3-year average Adjusted EPS Growth(2)
RSU | 40% | Continued service over 3-years

(1)Defined as the 3-Year Average Annual Adjusted NOPAT divided by the 3-Year Average Quarterly Invested Capital. Adjusted NOPAT is
Adjusted Attributable Net Income plus Adjusted Interest Expense net of Interest Income (tax effected at a normalized 25% rate).
Adjusted Attributable Net Income is defined as Net Income Available to Common Stockholders excluding foreign exchange gains/
losses on forward contracts related to financing, acquisition and integration related expenses, transaction related expenses,
transformational restructuring related expenses, financing charges in interest expense, the amortization of intangible assets, and
financial impacts associated with expected and actual dispositions of non-core businesses and assets. Adjusted Interest Expense
excludes financing charges in interest expense. Invested Capital is Attributable Shareholders Equity plus Total Debt less Cash and
Cash Equivalents (all per balance sheet). Quarterly Invested Capital is defined as the beginning and ending balance of each respective
quarter excluding (1) any balance with respect to all at-risk businesses to be sold and (2) changes to Accumulated Other
Comprehensive Loss (i.e., held flat at Q4 FY2024 ending actuals).
(2)Adjusted EPS Growth is calculated as (a) Adjusted Attributable Net Income (as defined in footnote 1) divided by (b) the Weighted
Average Number of Common Shares Outstanding, on a diluted basis, for a fiscal year, including any impact from share repurchases.
The Compensation Committee sets performance targets that it believes to be rigorous and challenging. The targets for
ROIC and Adjusted EPS included in our PEP design constitute competitively sensitive information. Accordingly, the targets
are not disclosed here but align with the Company’s long-term plan and/or guidance provided to stockholders at the time the
targets were approved. Target levels are disclosed for cycles that have ended as shown in the "2025 Achievements and
Payouts" section below.
For fiscal 2025, t he Relative TSR goals measure performance against the S&P MidCap 400 index and are as follows:

Metric | Threshold | Target | Maximum
Relative TSR | 25th percentile | 50th percentile | 75th percentile

2025 Achievements and Payouts

Fiscal Year 2023 (PEP23)

PEP23 has a three-year performance period to measure ROIC and Relative TSR, and a 1-year, 2-year, and 3-year
performance period to measure average Adjusted EPS Growth. The table below details the final performance results.

Fiscal Years 2023  –  2025 | Threshold (0% Payout) | Target (100% Payout) | Maximum (200% Payout) | Actual | Actual Payout (%)
ROIC | 14.8% | 16.5% | 18.1% | 21.4% | 200.0%
Relative TSR | 25th percentile | 55th percentile | 75th percentile | 46 th percentile | 70.5%
Adjusted EPS Growth |  |  |  |  |
1-Year | 5.9% | 7.4% | 8.9% | 16.0% | 200.0%
2-Year | 8.9% | 11.1% | 13.3%
3-Year | 7.9% | 9.9% | 11.9%

Prior to approving the PEP23 payout, the Compensation Committee reviewed the Company’s stock price performance and
Relative TSR as compared to the peer group during the PEP23 performance period to confirm alignment between pay and
performance. The Compensation Committee determined that the Company’s stock price performance supported the PEP23
payout as the Company’s market capitalization increased by approximately $7.4 billion or 76% over the performanc e period.

Fiscal Years 2024 (PEP24) and 2025 (PEP25)

PEP24 and PEP25 have three-year performance periods to measure ROIC and Relative TSR, and a 1-year, 2-year, and 3-
year performance period to measure average Adjusted EPS Growth.
The Compensation Committee sets performance targets that it believes to be rigorous and challenging. Because pre-
established targets for financial metrics are competitively sensitive, they are not disclosed here. However, all targets align
with the Company’s long-term plan and/or guidance to stockholders and are designed to drive performance that further
enhances long-term stockholder value creation.
For PEP24 and PEP25 the Relative TSR goals are as follows:

Metric | Threshold (0% Payout) | Target (100% Payout) | Maximum (200% Payout)
Relative TSR | 25th percentile | 50th percentile | 75th percentile

For both PEP24 and PEP25, there is no payout below the 25th percentile and Relative TSR of 75th percentile or higher
would result in a 200% payout. Linear interpolation is applied for outcomes between those shown in the illustration above.

Other Programs, Policies and Guidelines
Other Programs, Policies and Guidelines

Stock Ownership Guidelines for Named Executive Officers

NEOs are subject to stock ownership guidelines, which helps to ensure that their interests are aligned with those of
stockholders. Under the guidelines, AECOM’s CEO is required to maintain ownership of AECOM stock at six times base
salary and the other NEOs at three times base salary. The minimum number of shares required to meet the guideline is
updated annually based on each executive’s salary and the 12-month trailing average AECOM stock price. Shares owned
directly and indirectly, restricted stock units and vested stock options/shares are counted toward the guidelines. NEOs have
five full fiscal years, starting from the date an executive is first subject to the guidelines, to comply.
The table below outlines the stock ownership of the NEOs as of October 1, 2025.

Named Executive Officers | Guideline — Salary Multiple | Actual — Salary Multiple
Troy Rudd | 6.0 | 24.3 |
Gaurav Kapoor | 3.0 | 8.6 |
Lara Poloni | 3.0 | 17.6 |
David Gan | 3.0 | 8.2 |

Benefit, Retirement and Perquisite Programs

To protect our executives’ health and well-being, facilitate the operation of the business, retain current executives and recruit
new executives, AECOM’s NEOs are eligible to participate in benefit plans that are available to a substantial amount of all
employees, including participation in retirement plans, medical insurance, dental insurance, life insurance, disability
insurance, and time-off programs. Further, the Company offers certain additional benefits only to executive officers and other
senior officers, where applicable, which consist of the following:
•Executive Annual Physical Program. AECOM provides an annual complete executive physical examination
benefit at no cost to each NEO.
•Executive Life Insurance. AECOM provides company paid life insurance coverage as a multiple of base salary
up to a maximum benefit of $2 million for each NEO.
•Executive Disability Program. AECOM provides an Executive Disability Program, which offers salary
replacement of up to 60% of base salary in the event of an executive’s disability (maximum $25,000 per month).
•AECOM Executive Deferred Compensation Plan. A non-qualified deferred compensation plan that enables
highly compensated U.S. employees to defer income tax on components of their compensation.
•Executive Relocation Policy. AECOM provides relocation support to our most senior leadership. Executives
draw from a budget to choose from a suite of relocation services.
•Perquisites. The Company believes that offering certain limited perquisites facilitates the operation of AECOM’s
business and assists in executive retention.

Employment Agreements, Severance Benefits and Change in Control Provisions

See the “Payments and Benefits Upon Termination or Change in Control” section of this Proxy Statement for a description of
the benefits provided to our NEOs under the AECOM Senior Leadership Severance Plan, the AECOM Technology

Other Programs, Policies and Guidelines

Clawback Provisions

In November 2023, the Board approved the Company’s updated clawback policy in compliance with Rule 10D-1 under the
Exchange Act and NYSE Listing Standards. The clawback policy requires the Company to recover incentive-based
compensation made to current and former executive officers that is granted, earned or vested based upon the attainment of
a financial reporting measure in the event of an accounting restatement due to material non-compliance with any financial
reporting requirement under U.S. securities laws.

Hedging and Anti Pledging

The Company’s insider trading policy prohibits all directors, executive officers (as defined by Section 16 of the Exchange
Act) and certain other employees designated as insiders from engaging in any hedging or monetization transactions, such
as zero cost collars and forward sale contracts, involving Company securities.
In addition, the policy prohibits directors, executive officers and employees from buying shares on margin and the pledging
of Company securities except in certain limited circumstances subject to Company approval and demonstration of the
individual’s ability to repay the applicable loan without selling such securities.

Policies and Practices Related to the Timing of Option Awards

While we do not have a formal written policy in place with regard to the timing of awards of options in relation to the
disclosure of material, nonpublic information, the Compensation Committee does not seek to time equity grants based on
information about the Company that has not been publicly disclosed. It has been our recent practice to grant most of our
equity awards in the form of RSUs.

(1)Includes any amounts deferred under our qualified defined contribution plan or our non-qualified deferred compensation plan. For more
information regarding amounts deferred into the non-qualified deferred compensation plan, please refer to the “Executive Non-
Qualified Deferred Compensation for Fiscal Year 2025” table. The fiscal year 2025, 2024, and 2023 compensation amounts are for a
52-week fiscal year.
(2)These amounts represent the grant date fair value of the stock awards granted during the applicable fiscal year, calculated in
accordance with FASB ASC Topic 718 as described below and in the “Grants of Plan-Based Awards for Fiscal Year 2025” table.
The grant date fair value amounts in this column for fiscal year 2025 are based on the following calculations:
•The grant date fair value of PEP awards subject to financial performance vesting conditions is calculated based upon the number of
target PEP units granted multiplied by 66.7% and by the closing common stock price of $111.51, the trading day immediately before
the grant date for the awards issued on December 15, 2024, which fell on a weekend. The grant date fair value of PEP awards
subject to relative TSR market conditions is calculated based upon the number of target PEP units granted multiplied by 33.3% and
by the Monte Carlo value of $165.96 on December 15, 2024.
•The annual RSU awards granted on December 15, 2024 are calculated based upon the number of RSUs granted multiplied by the
closing common stock price of $111.51, the trading day immediately before the grant date, which fell on a weekend.
With respect to the PEP awards, these amounts represent the value based on the target performance as of the grant date. As
discussed in the Compensation Discussion and Analysis, two thirds, or 66.7%, of the PEP2025 awards are subject to performance
vesting conditions (ROIC and Adjusted EPS Growth) and one third, or 33.3%, are subject to a market condition (Relative TSR). The
value of the financial metrics portion (66.7%) of the PEP2025 awards based on maximum performance is as follows: Mr. Rudd —
$8,800,072 (59,188 PEP2025 units granted × 66.7% × $111.51 grant price × 200% maximum payout), Mr. Kapoor — $2,560,121
(17,219 PEP2025 units granted × 66.7% × $111.51 grant price × 200% maximum payout), Ms. Poloni — $2,800,090 (18,833 PEP2025
units granted × 66.7% × $111.51 grant price × 200% maximum payout), and Mr. Gan — $1,200,145 (8,072 PEP2025 units granted ×
66.7% × $111.51 grant price × 200% maximum payout). PEP2025 awards cliff vest after a three-year performance period on December
15, 2027 based on cumulative performance against performance goals and continued employment over that period (except in the case
of certain qualifying terminations). RSU awards cliff vest on the third anniversary of the grant date (December 15, 2027), subject to
continued employment through the applicable vesting date (except in the case of certain qualifying terminations).

Executive Nonqualified Deferred Compensation for Fiscal Year 2025

The following table sets forth information with respect to activity in the AECOM Executive Deferred Compensation Plan
(“EDCP”) during the fiscal year ended September 30, 2025. The EDCP is a non-qualified plan that enables eligible
employees to defer compensation in excess of amounts that may be contributed to the tax-qualified RSP. As with the RSP,
participants are allowed to defer base salary into the EDCP. The EDCP also permits deferral of sign on bonuses and annual
incentive bonuses. Up to 50% of base salary and 100% of any eligible bonus may be deferred into the EDCP. The EDCP
offers a fixed rate of return, which is determined based on the September 30, 2024 Prime Rate.

Payments and Benefits Upon Termination or Change in Control

Payments and benefits that would be provided to each NEO in addition to those received by all employees (such as payout
of accrued salary and paid time off) as a result of certain termination events are set forth in the table below. The amounts
shown assume a qualifying termination of employment effective as of the last day of our fiscal year ended September 30,
2025.
Agreements with NEOs
The Company has entered into a letter agreement with Mr. Rudd dated June 13, 2020 (the “Rudd Agreement”), pursuant to
which he is eligible to participate in the Senior Leadership Severance Plan as described below, except that he is eligible to
receive a severance multiple of two (2) times base salary (rather than one (1) times base salary). In addition, the Rudd
Agreement provides that Mr. Rudd is eligible for the severance payments and benefits provided under the Change in Control
Severance Policy for Key Executives, with the following modifications: (a) his lump sum cash severance benefit will equal
two (2) times (rather than one (1) times) his annual base salary; and (b) his lump sum payment in respect of healthcare
premiums will be multiplied by 24 (rather than 12).
On March 1, 2023, the Company entered into an employment agreement with Ms. Poloni (the “Poloni Agreement”). The
employment is at-will and may be terminated at any time for any reason, with or without notice, by Ms. Poloni or the
Company. The Poloni Agreement provides that Ms. Poloni is eligible for severance payments and benefits provided under
the Change in Control Severance Policy for Key Executives and Senior Leadership Severance Plan.
Cash Severance Plan
In December 2024, the Compensation Committee approved the Executive Officer Cash Severance Policy (the “Cash
Severance Plan”). Pursuant to the Cash Severance Plan, any new employment agreement, any new severance, separation,
or change of control agreement or similar arrangement, and any new severance plans or policies, with or applicable to any
of our executive officers, will not permit cash severance benefits to exceed 2.99 times the sum of the executive officer’s
base salary and annual target bonus without the approval or ratification of our stockholders.
Senior Leadership Severance Plan
In June 2020, the Compensation Committee approved the AECOM Senior Leadership Severance Plan (the “Severance
Plan”). Each named executive officer currently employed by the Company is an eligible employee under the Severance
Plan. The Severance Plan provides that, upon the termination of employment of an eligible employee by the Company other
than for Cause (as defined in the Severance Plan) or due to death or disability (other than any such termination in
connection with a change in control of the Company), in addition to the payment of accrued obligations, the eligible
employee will receive the following compensation and benefits from the Company: (i) a lump sum payment equal to one (1)
times the eligible employee’s base salary (except with respect to Troy Rudd, whose multiple is two (2) times base salary); (ii)
a prorated target bonus for the fiscal year in which the termination occurred based on the number of days of service in the
fiscal year; (iii) additional service vesting credit for purposes of outstanding equity awards based on the eligible employee’s
years of service with the Company (12 months of credit for five to ten years of service and 24 months of credit for more than
ten years of service); and (iv) a lump sum payment in respect of the monthly employer portion of healthcare premiums
multiplied by 12 (except with respect to Mr. Rudd, for whom the monthly employer portion of the premiums is multiplied by
24). The receipt of the foregoing severance payments and benefits will be subject to the eligible employee’s execution of a
separation and release agreement that contains customary restrictive covenants, including obligations with respect to
confidentiality and restrictions on soliciting the Company’s employees and customers.

Executive Compensation Tables
Change in Control Severance Policy for Key Executives
Pursuant to the AECOM Technology Corporation Change in Control Severance Policy for Key Executives (the “CIC Plan”),
the NEOs in the table below will receive the following benefits from the Company in connection with a Change in Control (as
defined in the CIC Plan):
•Upon a Change in Control only (“single trigger”): (i) full vesting acceleration of equity awards only if the surviving
entity does not continue or substitute such awards post-closing and (ii) deemed satisfaction of PEP Award targets
based on actual performance through the change in control date and conversion of the earned PEPs to unvested
RSUs that will continue to vest based on continued employment through the time based vesting period for the
PEPs (generally through December 15 following the end of the PEP performance cycle).
•Upon a termination without Cause (as defined in the CIC Plan) or with Good Reason (as defined in the CIC Plan)
within the period that begins 90 days prior to a Change in Control and ends 24 months following a Change in
Control (“double trigger”): (i) full vesting acceleration of all unvested PEP (but based on actual performance through
the change in control date), stock option, RSU and other equity awards; (ii) a lump sum cash severance payment
equal to a multiple (two times for our CEO and 1.5 times for other NEOs) of the sum of the NEO’s base salary and
average bonus earned over the three years prior to the year of termination (but including only those years in which
the NEO was employed as a Key Executive of the Company); (iii) a pro rata annual bonus payment, under the
annual incentive compensation plan applicable to the executive, for the year in which the employment termination
occurs, based upon the number of full months between the beginning of the applicable annual performance period
and the executive’s last date of employment and the target level of performance and payable when bonuses are
otherwise payable to the Company’s executives; and (iv) continued health coverage for a number of years equal to
the severance multiple (i.e., two years for our CEO and 1.5 years for other NEOs).
The receipt of the foregoing severance payments and benefits will be subject to the eligible employee’s execution of a
general waiver and release of claims in a form provided by the Company (except as otherwise required by applicable law
with respect to eligible employees employed outside of the United States).
Long-Term Incentive Equity Award Agreements
Pursuant to the terms of each of the RSU and PEP awards (“Long-term Incentive” in the tables below) held by our NEOs,
upon the date of a termination of the executive’s employment as a result of death or disability, all unvested RSU awards will
vest in full and PEP awards will vest based on actual performance as of the termination date. Upon a termination of the
executive’s employment as a result of retirement, all RSU awards will forfeit upon retirement and all PEP awards will
continue to vest with payout after the end of the performance period at actual performance.

Code, then payments shall be provided either in full or reduced to an amount in which no portion of the benefits would be subject to
excise tax, whichever provides the greatest after-tax benefit to the executive. The amounts in the table represent the benefits without
consideration of reduction to avoid excise tax and based on assumption of a double-trigger event.
(2)Amounts in this row reflect values for vesting of both RSUs and PEP awards. Amounts for RSUs are based on the AECOM common

without cause, PEP awards are eligible to vest based on actual performance through the end of the performance period and amounts
reflect estimated actual performance as of September 30, 2025. In the event of death, disability, or involuntary termination upon a
change of control, PEP awards are eligible for full accelerated vesting based on actual performance through the termination date and
amounts reflect estimated actual performance as of September 30, 2025.

CEO Pay Ratio
CEO Pay Ratio

Pay Ratio

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

| Total Compensation |
CEO | $15,973,622 |
Median Employee | $74,214 |
Ratio | 215.2 |

Global Employee Data Set

To derive our global employee data set, we employed the following methodology and assumptions:
•Data Source: We used our global human resource system of record to aggregate employee information from our
various systems worldwide.
•Determination Date: Per the Regulation, registrants are allowed to identify a median employee every three years
unless there has been a change in employee population or compensation arrangements that would significantly
affect the pay ratio. For fiscal year 2025, we have used the same median employee as the prior fiscal year who
was identified using September 17, 2024 as the determination date, which falls within the last three months of the
prior fiscal year.

Consistently Applied Compensation Measure & Selection of Median Employee

To determine our median compensated employee, we used a Consistently Applied Compensation Measure (CACM). As our
CACM, we used Annual Base Compensation, defined as base salary rate taking into account the employee’s full-time or
part-time status and the employee’s scheduled hours of employment, plus any guaranteed 13th or 14th month period pay, as
of the Determination Date. We exchanged non-U.S. compensation to U.S. dollars applying the same fixed annual exchange
rate used in our filed periodic reports.
The SEC’s rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s
annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make
reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the
pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have
different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates
and assumptions in calculating their own pay ratios.

Each non-employee director receives an annual equity award with a value of $167,500 (except the Chairperson of the Board

Board receives an annual equity award prorated for the number of quarters he or she serves. Exequity provided an annual
report indicating our compensation for directors is consistent with market practice.
Non-employee directors are eligible to participate in the AECOM Executive Deferred Compensation Plan, pursuant to which
each director may elect to defer all or a portion of such director's cash retainer and/or RSU grants.

The Audit Committee is comprised of non-employee directors, all of whom are “independent” under the applicable listing

amended and restated, which has been adopted by the Board. A copy of the current Audit Committee Charter is available for
viewing on the “Corporate Governance” area of the “Investors” section of our website at www.aecom.com.
Management of the Company is responsible for the preparation, presentation, and integrity of the consolidated financial
statements, maintaining a system of internal controls and having appropriate accounting and financial reporting principles
and policies. The independent registered public accounting firm is responsible for planning and carrying out an audit of the
consolidated financial statements and an audit of internal control over financial reporting in accordance with the rules of the
Public Company Accounting Oversight Board (United States) and expressing an opinion as to the consolidated financial
statements’ conformity with U.S. generally accepted accounting principles (“GAAP”) and as to internal control over financial
reporting. The Audit Committee monitors and oversees these processes and is responsible for selecting and overseeing the
Company’s independent registered public accounting firm.
As part of the oversight process, the Audit Committee met four times during fiscal year 2025. Throughout the year, the Audit
Committee met with the Company’s independent registered public accounting firm, management and internal auditors, both

In the course of fulfilling its responsibilities, the Audit Committee did, among other things, the following:

public accounting firm, and its lead audit partner in its determination to recommend the retention of Ernst & Young
LLP, including by assessing the performance of Ernst & Young LLP from within the Audit Committee and from the
perspective of senior management and the internal auditor;
•considered whether the provision of non-audit services by Ernst & Young LLP to the Company is compatible with
maintaining the registered public accounting firm’s independence;
•reviewed and discussed with management and Ernst & Young LLP the audited consolidated financial statements
for the year ended September 30, 2025 and unaudited consolidated financial statements for the quarters ended
December 31, 2024, March 31, 2025, and June 30, 2025;
•reviewed management’s representations that the Company’s consolidated financial statements were prepared in
accordance with GAAP and present fairly the results of operations and financial position of the Company;

annual audit, the results of their examinations, their evaluation of the Company’s internal controls and the overall
quality of the Company’s financial reporting;
•received the written disclosures and letter from Ernst & Young LLP required by the applicable requirements of the
Public Company Accounting Oversight Board regarding Ernst & Young LLP’s communication with the Audit
Committee concerning independence, and discussed with Ernst & Young LLP its independence;
•monitored the reporting system implemented to provide an anonymous complaint reporting procedure;
•reviewed the scope of and overall plans for the annual audit and the internal audit program;
•reviewed new accounting standards applicable to the Company with the Company’s Chief Financial Officer, internal

Report of the Audit Committee of the Board of Directors
The Audit Committee also met with representatives of management, the internal auditors, legal counsel and Ernst & Young
LLP on a regular basis throughout the year to discuss the progress of management’s testing and evaluation of the
Company’s system of internal control over financial reporting in response to the applicable requirements of the Sarbanes-
Oxley Act of 2002 and related U.S. Securities and Exchange Commission regulations. At the conclusion of this process, the
Audit Committee received from management its assessment and report on the effectiveness of the Company’s internal
controls over financial reporting. In addition, the Audit Committee received from Ernst & Young LLP its attestation report on
the Company’s internal control over financial reporting. These assessments and reports are as of September 30, 2025. The
Audit Committee reviewed and discussed the results of management’s assessment and Ernst & Young LLP’s attestation.
In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors,
and the Board has approved, that the audited consolidated financial statements be included in the Company’s Annual
Report on Form 10-K for the fiscal year ended September 30, 2025, for filing with the U.S. Securities and Exchange
Commission. The Audit Committee also approved the appointment of Ernst & Young LLP as the Company’s independent
registered public accountants for the fiscal year ending September 30, 2026 and recommended that the Board submit this
appointment to the Company’s stockholders for ratification at the 2026 Annual Meeting.

Reconciliation of Non-GAAP Items

Our proxy contains financial information calculated other than in accordance with U.S. generally accepted accounting
principles (“GAAP”). In particular, the Company believes that non-GAAP financial measures such as NSR, segment adjusted
operating margin on NSR, adjusted EBITDA, adjusted EPS, free cash flow and net leverage, provide a meaningful
perspective on its business results as the Company utilizes this information to evaluate and manage the business. We use
adjusted EBITDA and adjusted EPS to exclude the impact of certain items, such as amortization expense and taxes to aid
investors in better understanding our core performance results. We use free cash flow to present the cash generated from
operations after capital expenditures to maintain our business. We present NSR to exclude pass-through subcontractor
costs from revenue to provide investors with a better understanding of our operational performance. We present NSR
segment adjusted operating margin to reflect segment operating performance of our Americas and International segments,
excluding AECOM Capital and G&A. We also use net leverage, which is comprised of EBITDA as defined in the Company’s
credit agreement dated October 17, 2014, as amended, and total debt on the Company’s financial statements, net of total
cash and cash equivalents. Our non-GAAP disclosure has limitations as an analytical tool, should not be viewed as a
substitute for financial information determined in accordance with GAAP, and should not be considered in isolation or as a
substitute for analysis of our results as reported under GAAP, nor is it necessarily comparable to non-GAAP performance
measures that may be presented by other companies.
