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, free cash flow, 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 achievability; 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 to maintain a specific equity stake in the Company to align the interests of management with stockholders. The CEO ownership guideline is six times the base salary and the guideline for other NEOs is three times base salary.
Independent Consultant — We utilize the services of an independent compensation consultant who does not provide any other services to the Company.
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 cash severance policy that does not allow cash severance benefits to exceed 2.99 times the sum of an executive officer’s base salary and annual target bonus without approval of our stockholders.

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

FEBRUARY 28, 2025

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 2025 Annual Meeting of

Stockholders (“ 2025 Annual Meeting”) to be held on February 28, 2025 , at 10:00 a.m. Central Time , or at any adjournment

or postponement thereof. At the 2025 Annual Meeting, you will be asked to consider and vote on the matters described in

this Proxy Statement and in the accompanying notice. The 2025 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/MGQPQSJ .

Only common stockholders of record at the close of business on January 6, 2025 , which is the record date for the 2025

Annual Meeting, are permitted to vote at the 2025 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 2026 Annual Meeting of Stockholders.

  1. Ratify the selection of Ernst & Young LLP as our independent registered public accounting firm for fiscal year

2025 .

  2. Consider and act upon a stockholder proposal regarding the ratification of severance compensation, if properly

presented.

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 17, 2025 , we began

mailing a Notice of Internet Availability of Proxy Materials (the “Notice”) to all stockholders of record as of January 6, 2025

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.

The Notice of Internet Availability of Proxy Materials, Proxy Statement and our Annual Report on Form 10-K are

available at investors.aecom.com.

AECOM 9 2025 PROXY STATEMENT

Annual Meeting Information

Proxies

You may vote your shares at the 2025 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 2025 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 2025 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, except for Proposal 5, which they will vote against. Our Board is unaware of any

matters other than those described in this Proxy Statement that may be presented for action at our 2025 Annual Meeting. If

other matters do properly come before our 2025 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 2025 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 2025 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 2025 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 6, 2025 as the record date for determining the stockholders who are entitled to notice of, and to

vote at, our 2025 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 2025 Annual Meeting. As of the record date, there were 132,638,745 shares of

our common stock outstanding held by 1,371 record holders. A majority of the stock issued and outstanding and entitled to

vote must be present at our 2025 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 2025 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 2025 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 10 2025 PROXY STATEMENT

Our Board urges you to vote promptly by (1) electronically submitting a proxy or voting instruction card over the Internet, (2)

AECOM 11 2025 PROXY STATEMENT

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 12 2025 PROXY STATEMENT

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 2025 Annual Meeting. Directors elected at the 2025 Annual Meeting will serve until the 2026 Annual

Meeting of Stockholders and until their successors are duly elected and qualified. If a quorum is present at our 2025 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 9 directors on our Board. As previously announced, director

Lydia Kennard notified the Board in November 2024 that she will not stand for re-election to the Board at the 2025 Annual

Meeting. Accordingly, we are nominating 8 director nominees at the 2025 Annual Meeting. 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 and to assess the effectiveness of efforts at pursuing diversity. From

time to time, while identifying director candidates, the Nominating Committee may establish specific skills and experience

that it believes the Company should seek 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 and perspectives and should include representation of individuals from underrepresented communities,

including people of different genders, experiences, ages, races and ethnic backgrounds.

AECOM 20 2025 PROXY STATEMENT

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, 2025 . 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 2025 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 2025 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 2025 .

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 first year in

that role.

AECOM 21 2025 PROXY STATEMENT

Vote Required and Recommendation of the Board of Directors

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

of the shares of common stock present or represented by proxy and entitled to vote on the proposal at the 2025 Annual

Meeting. Abstentions will be counted as present and will have the effect of a vote against the proposal. Brokers have

discretion to vote on the ratification of our independent registered public accounting firm and, as such, no votes on this

proposal will be considered broker non-votes.

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

AECOM 22 2025 PROXY STATEMENT

Proposal 3

Approval of an Amendment to the Company's Certificate

of Incorporation to Update the Exculpation Provision

Under the Delaware General Corporation Law

The Company’s Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) currently includes an

exculpation provision for directors in Article SIXTH, as allowed under Section 102(b)(7) of the General Corporation Law of

the State of Delaware (the “DGCL”). Pursuant to a recent amendment to Section 102(b)(7) of the DGCL that became

effective on August 1, 2022, a Delaware corporation is now permitted to similarly eliminate or limit the personal liability of its

officers for monetary damages for breach of the officer’s duty of care, subject to limitations described below. The Board of

Directors determined that it is in the best interests of the Company and our stockholders, and has unanimously adopted a

resolution, to amend our Certificate of Incorporation (the “Charter Amendment”) to replace Article SIXTH with the following

(substantive changes are marked):

SIXTH: The Board shall have power, without stockholder action, to make Bylaws for the Corporation and to amend,

alter or repeal any Bylaws.

The powers and authorities herein conferred upon the Board are in furtherance and not in limitation of those

conferred by the laws of the State of Delaware. In addition to the powers and authorities herein or by statute

expressly conferred upon it, the Board may exercise all such powers and do all such acts and things as may be

exercised or done by the Corporation, subject, nevertheless, to the provisions of the laws of the State of Delaware,

of this Amended and Restated Certificate of Incorporation and of the Bylaws of the Corporation.

To the full extent permitted by Section 102(b)(7) of the General Corporation Law of the State of Delaware, the

personal liability of a director or officer to the Corporation or its stockholders for monetary damages for breach of

fiduciary duty as a director or officer shall be eliminated; provided, however, that such personal liability shall not be

eliminated hereby (i) for any breach of the director’s or officer’s duty of loyalty to the Corporation or its

stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing

violation of law, (iii) for any director under Section 174 of the General Corporation Law of the State of Delaware,

(iv) for any director or officer for any transaction from which the director or office r derived an improper personal

benefit, (v) for any officer in any action by or in the right of the Corporation or (v i ) for any act or omission

occurring prior to the date when this provision shall have become effective pursuant to Sections 242, 245 and 103

of the General Corporation Law of the State of Delaware . Elimination of such personal liability is not intended to

eliminate or narrow any protection otherwise applicable to directors or officers .

If the stockholders approve the Charter Amendment, promptly following the 2025 Annual Meeting, we will file a Certificate of

Amendment to our Certificate of Incorporation in the form attached hereto as Annex B with the Delaware Secretary of State.

The only changes to the Certificate of Incorporation are to Article SIXTH.

The Charter Amendment would expand the existing director exculpation provision in our Certificate of Incorporation, as

provided for under the DGCL, to also apply to officers. The Board of Directors strongly believes that the Company’s officers

should be held to the highest standards when carrying out their duties to the Company and our stockholders. Nevertheless,

the potential for officers to have personal liability for decisions made or actions taken on behalf of the Company, including for

unintentional mistakes, could adversely affect the ability of our officers to make decisions that are most appropriate for the

Company and thereby maintain these high standards, and also increase the costs of the Company in defending litigation.

The effect of the Charter Amendment is to limit the ability of our stockholders to seek monetary damages directly against our

officers. If implemented, the Charter Amendment would allow for the exculpation of certain officers in connection with direct

claims brought by stockholders, including class actions. However, this provision does not limit the Company’s rights or the

rights of any stockholder to seek monetary damages against an officer for a breach of the duty of loyalty, acts or omissions

not in good faith or which involve intentional misconduct or a knowing violation of law, transactions in which an officer

derives an improper personal benefit, or any actions brought by the Company directly against the officer or by any of our

stockholders through a derivative suit on the Company’s behalf. For these reasons, the proposal provides covered officers

with less exculpation than is afforded to directors because officers remain subject to due care claims in derivative suits and

direct suits brought by the Company. If the Charter Amendment is adopted, certain specified company officers, which would

include the roles held by our NEOs, would be subject to this provision.

AECOM 23 2025 PROXY STATEMENT

Our Board of Directors desires to make the proposed amendment to maintain provisions consistent with the governing

statutes contained in the DGCL and believes that amending our Certificate of Incorporation to add the authorized liability

protection for certain officers, consistent with the protection currently in our Certificate of Incorporation for our directors, is

necessary in order to continue to attract and retain experienced and qualified officers, especially as companies with whom

we may compete for talent adopt similar exculpation provisions. The Board of Directors believes that in the absence of such

protection, qualified officers might be deterred from serving as officers of the Company due to exposure to personal liability

and the risk that substantial expense may be incurred in defending lawsuits, regardless of merit.

Given the potential benefits anticipated to accrue to the Company, including the associated benefits to our stockholders, and

the limited types of claims that would be exculpated, the Board of Directors views this proposal as a rational limit on officer

liability and recommends that stockholders approve the amendment to our Certificate of Incorporation as described herein.

When considering the recommendation of the Board of Directors that our stockholders approve this proposal, our

stockholders should be aware that certain directors and executive officers of the Company, specifically our Chief Executive

Officer and our NEOs, have interests in the proposal that may be different from, or in addition to, the interests of our

stockholders more generally because they will receive the liability exculpation protections afforded by the Charter

Amendment if it is adopted. The Board of Directors was aware of these interests and considered them, among other

matters, in reaching its decision to approve the Charter Amendment.

Vote Required and Recommendation of the Board of Directors

The affirmative vote of a majority of the outstanding shares of common stock entitled to vote on the proposal at the 2025

Annual Meeting is required to approve the amendment to the Company’s Certificate of Incorporation to update the

exculpation provision under the Delaware General Corporation Law. Abstention and broker non-votes will have the effect of

a vote against the proposal.

The Board of Directors recommends that you vote FOR the proposal to amend the Certificate of Incorporation

AECOM 24 2025 PROXY STATEMENT

Proposal 4

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 2025 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 2025 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 2025 Annual Meeting is required to approve the advisory resolution on the Company’s executive

compensation. Abstentions will be counted as present and will have the effect of a vote against the proposal. Broker non-

votes will not be counted as participating in the voting on the proposal and will therefore have no effect on the outcome of

the vote on the proposal.

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

Proposal 5

Stockholder Proposal Regarding the Ratification of

Severance Compensation

Mr. John Chevedden, 2215 Nelson Avenue, No. 205, Redondo Beach, California 90278, who has represented that he owns

100 shares of the Company’s common stock, has requested that we include the following stockholder proposal and

supporting statement in our proxy statement for the 2025 Annual Meeting which is excerpted in its entirety below. The

stockholder proposal is required to be voted on at the 2025 Annual Meeting only if properly presented at the meeting.

The Board of Directors recommends a vote AGAINST this proposal for the reasons stated under "Recommendation

and Rationale of the Board of Directors", which follows the proposal.

Proposal 5 – Shareholder Ratification of Golden Parachutes

Shareholders request that the Board seek shareholder approval of any senior manager's new or renewed pay

package that provides for severance or termination payments with an estimated value exceeding 2.99 times the

sum of the executive's base salary plus target short-term bonus. This proposal only applies to the Named Executive

Officers.

"Severance or termination payments" include cash, equity or other pay that is paid out or vests due to a senior

executive's termination for any reason. Payments include those provided under employment agreements,

severance plans, and change-in-control clauses in long-term equity plans, but not life insurance, pension benefits,

or deferred compensation earned and vested prior to termination.

"Estimated total value" includes: lump-sum payments; payments offsetting tax liabilities, perquisites or benefits not

vested under a plan generally available to management employees, post-employment consulting fees or office

expense and equity awards if vesting is accelerated, or a performance condition waived, due to termination.

The Board shall retain the option to seek shareholder approval after material terms are agreed upon.

This proposal is relevant even if there are current golden parachute limits. A limit on golden parachutes is like a

speed limit. A speed limit by itself does not guarantee that the speed limit will never be exceeded. Like this proposal

the rules associated with a speed limit provide consequences if the limit is exceeded. With this proposal the

consequences are a non-binding shareholder vote is required for unreasonably rich golden parachutes.

This proposal places no limit on long-term equity pay or any other type pay. This proposal thus has no impact on

the ability to attract executive talent and does not discourage the use of long-­term equity pay because it places no

limit on golden parachutes. It simply requires that overly rich golden parachutes be subject to a non binding

shareholder vote at a shareholder meeting already scheduled for other matters.

This proposal is relevant because the annual say on executive pay vote does not have a separate section for

approving or rejecting golden parachutes.

Shareholder Ratification of Golden Parachutes — Proposal 5

AECOM 26 2025 PROXY STATEMENT

Recommendation and Rationale of the Board of Directors

The Board of Directors considered the stockholder proposal and, for the reasons outlined below, believes that the proposal

is not in the best interest of the Company and its stockholders.

The Company already has a carefully tailored policy, which requires stockholder approval of cash severance

payments to executive officers in excess of 2.99 times the sum of base salary and annual target bonus.

The Company recently adopted an Executive Officer Cash Severance Policy (the “Cash Severance Policy”) and upon the

recommendation of the Compensation Committee. Under the Cash Severance Policy, any new employment agreement, any

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. The

Board believes that the Cash Severance Policy is more carefully tailored and appropriate for the Company than the one set

forth in the proposal and allows the Company to appropriately limit compensation, while still being competitive in the market

for talent.

Both our longstanding, publicly available severance plans already limit cash severance payments to an amount

below 2.99 times base salary and target bonus in nearly all cases.

In addition to the policy discussed above, the Company already has market-appropriate severance plans that provides for

limited severance payments. Under the AECOM Senior Leadership Severance Plan (the “Severance Plan”), upon a

termination of employment by the Company other than for cause 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, an

NEO will receive a cash payment, among other specified benefits, consisting of (i) one (1) times base salary (except with

respect to our CEO whose multiple is two (2) times base salary), (ii) a prorated target bonus, and (iii) the monthly employer

portion of healthcare premiums multiplied by 12 (except with respect to our CEO, for whom the monthly employer portion of

the premiums is multiplied by 24).

Under the AECOM Technology Corporation Change in Control Severance Policy for Key Executives (the “CIC Plan”), upon a

termination without cause or with good reason within 90 days before or 24 months after a change of control of the Company,

an NEO will receive a cash payment, among other specific benefits, consisting of (i) 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, (ii) a pro rata target annual bonus, and (iii) 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).

In nearly all cases, cash payments under either the Severance Plan or CIC Plan would be significantly below 2.99 times

base salary and target bonus.

The limits the proposal seeks to impose are inconsistent with the widely recognized value that stockholders place

on equity compensation.

Equity compensation is an important element of our compensation program and is intended to align the long-term interests

of our NEOs with those of our stockholders. By including the value of outstanding equity awards that accelerate upon a

termination event in the “estimated total value” to be applied against the limit, the proposal would break that alignment by

de-emphasizing the importance and value of equity compensation and reducing the incentive.

Under the Severance Plan, the CIC Plan and the Company’s award agreements for our NEOs, full accelerated vesting of

equity awards occurs in limited circumstances, including: (1) termination by reason of death; (2) termination by reason of

disability; and (3) termination within 90 days before or 24 months after a change of control of the Company, when an

employee’s termination is without cause or for good reason (i.e., double trigger vesting). If, unrelated to a change of control,

the NEO’s employment is terminated without cause, then additional service vesting credit is provided based on the NEO’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). These limited acceleration provisions are consistent with market practice and were approved by the

Compensation Committee after consultation with its independent compensation consultant. In addition to not penalizing

NEOs or their families in the unfortunate event of their disability or death, our policies on equity compensation are designed

to provide market level standards of compensation and to incentivize our NEOs to remain with the Company to maximize

value for our stockholders in the event of a change of control of the Company.

AECOM 27 2025 PROXY STATEMENT

The proposal could create increased risk for stockholders and create a misalignment between our NEOs and our

stockholders during a change-in-control transaction.

Without this incentive to retain NEOs during a potential change in control, our ability to deliver maximum stockholder value in

such a transaction could be impaired. The proposal would significantly limit the Board’s flexibility to provide reasonable

assurance to our NEOs that they could realize the full expected value of their previously granted equity awards even if a

change-in-control transaction were completed. The risk of job loss following a change in control, coupled with a limit on the

value that may be realized from previously granted equity awards, may present an unnecessary distraction for our NEOs

and could lead them to begin seeking new employment while a transaction is being negotiated or pending.

The CIC Plan was designed to avoid distractions and potential conflicts of interest that could otherwise arise when a

potential change-in-control transaction is being considered. They permit our leadership team to remain focused on protecting

stockholder interests and maximizing stockholder value. If the potential change-in-control transaction is in the best interests

of our stockholders, our NEOs should be motivated to focus their full energy on pursuing this alternative, even if it is likely to

result in the termination of their employment.

The Company’s post-termination compensation practices are consistent with current market standard and are

benchmarked against the practices of our peers.

The Compensation Committee, composed entirely of independent directors, works throughout the year reviewing

compensation trends, evaluating changing market standards, reviewing feedback from stockholders, and considering

changes to executive compensation that will provide the Company’s executive officers with an incentive to achieve superior

financial results and align pay with performance. Upon a review by the Compensation Committee and its independent

compensation consultant, the Board believes that our existing compensation program and practices are market standard

and align with the interests of our executive officers and our stockholders.

Given the undue limitations and negative consequences that could accompany the policy set forth in the proposal, it is not

surprising that none of the companies in our peer group disclose having a severance policy as over broad as the policy

requested by the proposal.

Adoption of the policy set forth in the proposal could adversely impact the Company’s ability to attract, motivate,

and retain highly qualified talent.

Adoption of this proposal would hinder the Company’s ability to use long-term equity awards to competitively recruit and

retain qualified executives. We operate in a highly competitive industry, competing with some of the largest companies in the

world for talented executives. The Board and the Compensation Committee must maintain the ability to provide an overall

compensation program that is market competitive and is capable of attracting and retaining top talent and driving long-term

performance and stockholder value. Each element of the Company’s current compensation program including its Severance

Plan and CIC Plan, is intended to fulfill this business necessity. As noted above, our peers do not have policies as broad as

the one included in the proposal, and adopting the broad approach this proposal requests would disadvantage the Company

relative to our peers in our ability to recruit and retain the best available executive talent. The Company would also likely

have to increase its base cash compensation in order to try to remain competitive from a total compensation package

perspective.

Moreover, the benefits that would be covered by the policy set forth in the proposal often arise in the context of negotiating

an employment agreement with an outside hire for an executive officer leadership position, particularly when a sign-on or

similar one-time equity award is part of the overall compensation package necessary to induce the individual to leave a

successful and well-compensated role at another company. If one-time equity awards are required to be applied against the

limit, receipt of stockholder approval would practically be required to hire potential candidates, and such candidates may not

be willing to have their hiring subject to stockholder approval. As a result, implementing the proposal may interfere with the

Board’s ability to act in the best interests of the Company and make binding offers of employment, including for roles that

could have significant impact on our performance and results. Similar dynamics can exist in developing compensation

packages to retain employees.

In sum, the Board believes that the Company’s current executive compensation policies and practices, including the Cash

Severance Policy recently adopted, and its other plans, contracts, and policies governing post-termination compensation,

are reasonable, appropriate, and market-standard, and they effectively align the interests of our executives with those of our

stockholders. Adoption of this proposal would limit the Compensation Committee’s discretion and flexibility to tailor the

executive compensation program to meet the Company’s evolving needs and effectively recruit, motivate, and retain critical

talent, and therefore would not be in the best interests of our stockholders.

Corporate Governance

Board Meetings

During our fiscal year ended September 30, 2024 , our Board met five times, the Audit Committee met eight 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 2024 .

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

The Company’s Corporate Governance Guidelines provide that the Board shall determine whether or not the roles of

Chairman and CEO should be held by the same individuals or separate individuals based on the Company’s circumstances

and needs at any given time. If the roles of Chairman and CEO are held by the same individual, the Board will select a Lead

Independent Director.

In November 2024 , the Board determined to combine the roles of Chairman and CEO and elected Troy Rudd to the

combined role effective as of re-election at the 2025 Annual Meeting on February 28, 2025. The Board also elected Douglas

W. Stotlar, who has served as Chairman since August 2020, to serve as Lead Independent Director, effective as of re-

election at the 2025 Annual Meeting. 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. The Board also believes that the combination of the roles

further encourages the long-term commitment of Mr. Rudd to the Company and ensures continuity in the Company’s

succession planning process.

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 30 2025 PROXY STATEMENT

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 2024 , executive sessions were held at each regularly scheduled Board and

committee meeting. Executive sessions are currently chaired by the Chairman 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:

We believe the division of risk management responsibilities described above provides an effective framework for evaluating

Risk Assessment of Compensation Policies and Practices

In fiscal year 2024 , 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 31 2025 PROXY STATEMENT

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

Audit Committee. The Audit Committee, which is composed solely of independent directors as defined under Rule

10A-3(b)(1) of the rules of the U.S. Securities and Exchange Commission and the regulations of the NYSE, appoints the

Company’s independent auditors, reviews the results and scope of the audit of our financial statements as well as other

services provided by our independent auditors, reviews and approves audit fees and all non-audit services as well as

reviews and evaluates our audit and control functions, including our internal audit function. Our 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 eight meetings during fiscal year 2024 .

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 2024 .

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 four meetings during fiscal year 2024 .

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 and to assess the effectiveness of efforts at pursuing diversity. From

time to time, while identifying director candidates, the Nominating Committee may establish specific skills and experience

that it believes the Company should seek to constitute a balanced and effective B oard.

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 is views as particularly important:

• senior leadership experience;

• industry experience;

• public company experience;

• financial expertise;

• government/regulatory expertise; and

• international expertise.

The Nominating Committee believes that it is essential that Board members represent diverse viewpoints and backgrounds.

In identifying and selecting individuals, the Board and the Nominating Committee consider diversity, age, gender, skills, and

such other factors as they deem appropriate to maintain a balance of knowledge, experience and capability. In addition, the

Nominating Committee believes the Board should encompass individuals with diverse backgrounds and perspectives and

representation of individuals from underrepresented communities. Diversity is an important consideration in the director

nomination process because the Board believes that people of different genders, experiences, ages, races and ethnic

AECOM 34 2025 PROXY STATEMENT

backgrounds can contribute different, useful perspectives, while collaborating effectively to further the Company’s objectives.

In November 2024, Lydia H. Kennard informed the Board that she will not stand for reelection to the Board at the 2025

Annual Meeting. The Board is committed to appointing a racially and/or ethnically diverse director within a year of the 2025

Annual Meeting.

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 2024 , 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 2024 Annual Meeting.

Director Compensation

Information regarding the compensation of our non-employee directors is discussed below in “Directors' Compensation for

Fiscal Year 2024 .”

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.

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 2024 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, 2024 . All current non-employee directors already meet or are

expected to meet guidelines within the five (5) year transition period.

including record backlog in the design business, which increased by 5%.

• Strong Balance Sheet and Financial Performance supported approximately $560 million of capital allocated to

stockholders through share repurchases and dividends in fiscal year 2024 , while our balance sheet remained strong with

low net leverage of 0.8x. Reflecting confidence in our long-term growth prospects, strength of our cash flow and strong

balance sheet, our Board of Directors approved increases to our stock repurchase authorization to $1 billion and an 18%

generally) as follows:

AECOM 41 2025 PROXY STATEMENT

All core elements of our executive pay program are consistent with our compensation philosophy and are directly linked to

individual and Company performance as follows:

Pay Element What It Does How It Links to Performance
Base Salary Provides competitive fixed cash compensation reflective of an executive’s role, responsibility, and experience • Salary is tied to performance in the role and the growth of the employee along with the Company. • Salary increases are not guaranteed and are evaluated annually by the Compensation Committee.
Annual Cash Bonus Rewards achievement of the Company’s annual financial plan, as well as the specific qualitative goals included in the Company’s strategic plan • Financial metrics for fiscal year 2024 include Adjusted EBITDA, Segment Adjusted Operating Margin on Net Service Revenue (NSR) and Free Cash Flow; each of these metrics are key indicators of value creation. • Strategic non-financial measures include safety, leadership development, and sustainability goals, which drive employee satisfaction and retention. • Financial targets align with external guidance. • Payments may range from 0% to 200% of target based on actual performance and are not guaranteed.
Performance-Based Equity Aligns long-term interests of executive and stockholders Rewards achievement of performance related to the Company’s long-term objectives and stockholder value creation Retains key talent and rewards creation of long-term stockholder value 60% of long-term equity incentives • Performance metrics for fiscal year 2024 include ROIC, Adjusted EPS Growth, and Relative TSR to align compensation with long-term profitable growth, disciplined risk management, and stockholder value creation. • The final value of the performance-based equity award is determined by AECOM’s performance against challenging standards as well as total stockholder return. • Payments may range from 0% to 200% of target based on actual performance and are not guaranteed.

Process and Decisions

Executive Pay Philosophy

Our executive pay program is designed to support our strategy to deliver industry leading profitable growth and stockholder

value creation. It is underlined by our compensation philosophy that aims to attract and retain the best and brightest in our

industry and recognize and reward outstanding achievements that drive long-term profitable growth and create stockholder

value.

Pillars of our Executive Pay Program

Market Competitive: Assess NEO target pay levels against market compensation 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 43 2025 PROXY STATEMENT

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

2024 , 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 44 2025 PROXY STATEMENT

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 2024 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. The 2024 peer group was unchanged from 2023 .

Elements of Our Named Executive

Officer Compensation

The following is a discussion of the primary elements of fiscal year 2024 compensation for each of our NEOs. For 2024 , our

NEOs were:

– Troy Rudd, our Chief Executive Officer,

– Gaurav Kapoor, our Chief Financial & Operations Officer,

– Lara Poloni, our President, and

– David Gan, our Chief Legal Officer & General Counsel

Base Salaries

Our Compensation Committee adjusts the base salaries of our NEOs in connection with its periodic review of each NEO’s

performance, any change in responsibility, and competitive talent market conditions. The following sets forth the fiscal year

2024 b ase salary increases for each NEO:

NEOs 2023 ($) 2024 ($)(1) Percent Change (%)
Troy Rudd 1,275,000 1,326,000 4.0
Gaurav Kapoor 770,400 810,000 5.1

(1) Salary increase, as applicable, effective January 1, 2024 with the beginning of the calendar year. Salaries disclosed in the “Summary

Compensation Table” reflect actual amounts earned for the applicable fiscal year.

The Compensation Committee believes that our NEOs’ base salary levels provide appropriate levels of fixed income based

on the background, qualifications and skill set of each executive.

Annual Incentives

Our Compensation Committee establishes a short-term incentive award opportunity to be paid to each NEO upon achieving

certain annual individual and company performance goals under the Executive Incentive Plan (“EIP”). For fiscal year 2024 ,

the Compensation Committee approved the following targets, shown as a percentage (%) of base salary and in dollar

amounts ($), for the NEOs:

Annual Target Incentives (NEOs) — Troy Rudd 2023 (1) — 125% $1,593,750 2024 (1) — 140% $1,856,400
Gaurav Kapoor 100% $770,400 100% $810,000
Lara Poloni 110% $880,363 110% $924,000
David Gan 100% $586,500 100% $610,000

(1) Bonus targets reflect amounts approved as part of the annual compensation planning process for the fiscal year.

For fiscal year 2024 , the Compensation Committee approved performance measures for our NEOs as set forth in the table

below to support our strategy for attaining long-term profitable growth and stockholder value creation. The targets for each of

the financial metrics align with the initial earnings guidance provided to our stockholders and our financial plan as approved

by the Board.

AECOM 46 2025 PROXY STATEMENT

Metric Why Selected
Free Cash Flow Free cash flow both measures and incentivizes allocation of capital in a disciplined manner to high-return investments and encourages working capital conversion. Free cash flow is critical to our returns-based capital allocation policy.
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 and ESG 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 • Percentage of women in leadership of greater than 20%, consistent with the Company’s near-term targets included in its Sustainable Legacies strategy • Voluntary attrition of high-performers of less than 10%, which would exceed benchmark levels • 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 2024 , 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**
Free Cash Flow 30% $500.0 $625.0 $750.0 $708.4 50.0%
Adjusted EBITDA 30% $976.0 $1,085.0 $1,193.0 $1,094.8 32.7%

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 2024 , 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 • Extended Track Record of Delivering on All Key Financial Objectives: We delivered new records for net service revenue, margins, earnings and cash flow, highlighted by a 15.8% segment adjusted operating margin, 14% adjusted EBITDA growth and 22% adjusted EPS growth for the full year. Adjusted EBITDA and EPS exceeded the mid-points of both our original and increased guidance. Our margin performance and cash flow also exceeded guidance. • 'Winning What Matters', Positioning the Company for Continued Success: Our win rate remained at a record high at 50% and was even higher on our largest and most strategically valuable pursuits. In addition, our pipeline of opportunities remains at a record high, providing for excellent visibility. As a result, the earnings potential of the organization remains as strong as ever. • Invested 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 the launch of the Water and Environment Advisory global business line to capitalize on the substantial opportunity to provide higher-value advisory services to our clients, while continuing to invest in our Program Management global business line that grew nearly 20% in the year. These businesses are elevating our value proposition to clients at a time where they are looking to advance increasingly complex initiatives, which is further supporting our win rates and backlog growth. • Continued Strong 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, 77% 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 0.07 continues to be substantially ahead of peers and broader industry benchmarks. • Maximized Stockholder Value: Reflecting strong financial performance and balance sheet, we allocated approximately $560 million to stockholders through share repurchases and dividends. Our balance sheet remains a competitive advantage with 0.8x net leverage and approximately 70% of our debt fixed, swapped to fixed, or capped over the next several years and no bond maturities until 2027.

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

AECOM 49 2025 PROXY STATEMENT

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 2024 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 2024 :

NEOs 2023 ($) 2024 ($) Percent Change (%)
Troy Rudd 7,700,000 9,500,000 23.4
Gaurav Kapoor 2,000,000 2,900,000 45.0
Lara Poloni 2,100,000 3,100,000 47.6
David Gan 1,250,000 1,400,000 12.0

For fiscal year 2024 , 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 FY2023 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 "2024 Achievements and

Payouts" section below.

The Relative TSR goals measure performance against the Compensation Peer Group and are as follows :

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

2024 Achievements and Payouts

Fiscal Year 2022 ( PEP22 )

PEP22 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 2022  –  2024 Threshold (0% Payout) Target (100% Payout) Maximum (200% Payout) Actual Actual Payout (%)
ROIC 13.5% 15.0% 16.5% 18.6% 200.0%
Relative TSR 25th percentile 55th percentile 75th percentile 31 st percentile 19.2%
Adjusted EPS Growth
1-Year 12.9% 16.1% 19.3% 15.2% 200.0%
2-Year 10.1% 12.7% 15.2%
3-Year 9.0% 11.3% 13.5%

Prior to approving the PEP22 payout, the Compensation Committee reviewed the Company’s stock price performance and

Relative TSR as compared to the peer group during the PEP22 performance period to confirm alignment between pay and

performance. The Compensation Committee determined that the Company’s stock price performance supported the PEP22

payout as the Company’s market capitalization increased by approximately $4.2 billion or 44% over the performance period.

Importantly, as shown below, the Company’s stock also outperformed the broader stock market, as represented by the S&P

500 index, over that time period by near ly 50 % .

AECOM 51 2025 PROXY STATEMENT

Fiscal Years 2023 (PEP23) and 2024 (PEP24)

PEP23 and PEP24 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 PEP23 , the Relative TSR goals are as follows:

Metric Threshold (0% Payout) Target (100% Payout) Maximum (200% Payout)
Relative TSR 25th percentile 55th percentile 75th percentile

100% target payout for Relative TSR requires outperformance against the current Compensation Peer Group at the end of

the performance period at the 55th percentile.

For PEP24, the Relative TSR goals are as follows:

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

For both PEP23 and PEP24, 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

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, 2024 .

Named Executive Officers Guideline — Salary Multiple Actual — Salary Multiple
Troy Rudd 6.0 23.5
Gaurav Kapoor 3.0 10.3
Lara Poloni 3.0 11.8
David Gan 3.0 8.8

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

Corporation Change in Control Severance Policy for Key Executives, as well as agreements with certain of our NEOs.

AECOM 53 2025 PROXY STATEMENT

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 2024 ” table. The fiscal year 2024 , 2023 , and 2022 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 2024 ” table.

The grant date fair value amounts in this column for fiscal year 2024 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 common stock price of $92.28 on the day of grant for the awards issued on

December 15, 2023. 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 $130.52 on December 15, 2023.

• The annual RSU awards granted on December 15, 2023 are calculated based upon the number of RSUs granted multiplied by the

closing common stock price of $92.28 on the grant date.

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 PEP2024 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 PEP2024 awards based on maximum performance is as follows: Mr. Rudd —

$7,600,058 (61,679 PEP2024 units granted × 66.7% × $92.28 grant price × 200% maximum payout), Mr. Kapoor — $2,320,042

(18,856 PEP2024 units granted × 66.7% × $92.28 grant price × 200% maximum payout), Ms. Poloni — $2,480,117 (20,157 PEP2024

units granted × 66.7% × $92.28 grant price × 200% maximum payout), and Mr. Gan — $1,120,033 (9,103 PEP2024 units granted ×

66.7% × $92.28 grant price × 200% maximum payout). PEP2024 awards cliff vest after a three-year performance period on December

15, 2026 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, 2026), subject to

continued employment through the applicable vesting date (except in the case of certain qualifying terminations).

The “Grants of Plan-Based Awards for Fiscal Year 2024 ,” “Outstanding Equity Awards for Fiscal Year End 2024 ” and the “Option

Exercises and Stock Vested for Fiscal Year 2024 ” tables include additional information with respect to all awards outstanding as of

PEP awards will cliff vest 100% on December 15, 2026, following the close of the three-year vesting period, provided the

performance conditions are achieved, subject to continued employment through the vesting date (except in the case of certain

qualifying terminations).

• The annual RSU awards granted on December 15, 2023 are calculated based upon the number of RSUs granted multiplied by the

closing common stock price of $92.28 on the grant date. These annual RSU awards will cliff vest 100% on December 15, 2026,

subject to continued employment through the vesting date (except in the case of certain qualifying terminations).

Executive Nonqualified Deferred Compensation for Fiscal Year 2024

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, 2024 . 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, 2023 Prime Rate .

(1) Earnings were calculated using the rate of 8.50% and, to the extent exceeding 120% of the Applicable Federal Rate, were included in

the Non-qualified Deferred Compensation Earnings column of the “Summary Compensation Table”.

(2) $34,888 of this amount was reported as an executive contribution or earnings above the Applicable Federal Rate in the “Summary

Compensation Table” in prior year proxy statements. The information in this footnote is provided to clarify the extent to which amounts

payable as deferred compensation represent compensation reported in our prior proxy statements, rather than new deferrals of

compensation.

Payments and Benefits Upon Termination or Change in Control

Payments and benefits that would be provided to each NEO in addition to those received by all employees (such as payout

of 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,

2024 .

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

AECOM 61 2025 PROXY STATEMENT

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.

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).

AECOM 62 2025 PROXY STATEMENT

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, a pro rata portion of the unvested RSU2022 and PEP2022 awards will

vest. The proration will be calculated as a percentage where the denominator is the number of months in the vesting period

or performance cycle of the relevant award and the numerator is the number of whole months from the beginning date of the

vesting period or performance cycle through the date of the executive’s termination. PEP awards will pay out after the end of

the performance period at the lesser of actual performance or 100%. For awards granted in fiscal years 2023 and 2024 ,

RSU2023 and RSU 2024 awards will forfeit upon retirement and PEP2023 and PEP 2024 awards will continue to vest with

payout after the end of the performance period at actual performance.

(1) Under the Change in Control Severance Policy in the event that any benefit payable constitutes a “parachute payment” within the

meaning of Internal Revenue Code Section 280G and would be subject to excise tax imposed by Section 4999 of the Internal Revenue

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

stock closing price as of September 30, 2024, which was $103.27 per share. In the event of retirement or involuntary termination

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, 2024. 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, 2024.

(3) Amounts in this row also reflect values for vesting of option awards for Mr. Rudd. In the event of death, disability, involuntary

termination without cause, or involuntary termination upon a change of control, option awards are eligible for full accelerated vesting

and amounts reflected are the difference between the AECOM stock closing price as of September 30, 2024, and the exercise price of

unvested option awards. In the event of retirement, option awards are eligible for continued vesting and amounts reflected are the

difference between the AECOM stock closing price as of September 30, 2024, and the exercise price of unvested option awards.

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 $ 14,440,729
Median Employee $ 70,951
Ratio 203.5

Global Employee Data Set

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

• Data Source: We used our global human resource system of record to aggregate employee information from our

various systems worldwide.

• Determination Date: We selected September 17, 2024 which falls within the last three months of our most recently

completed fiscal year, as the determination date for identifying our median employee.

Consistently Applied Compensation Measure & Selection of Median Employee

To determine our median compensated employee, we used a Consistently Applied Compensation Measure (CACM). As our

CACM, we used Annual Base Compensation, defined as base salary rate taking into account the employee’s full-time or

part-time status and the employee’s scheduled hours of employment, plus any guaranteed 13th or 14th month period pay, as

of the Determination Date. We exchanged non-U.S. compensation to 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.

outperformed market indices and a 21% Adjusted EPS compounded growth rate , which reflects the Company’s

focus on shareholder value creation. As evidenced by this strong performance, as compared to fiscal 2021, CEO

and non-CEO CAP increased by 37% and 73% respectively in fiscal 2024 .

• Additionally, performance on other key metrics that drive long-term value creation, including free cash flow,

adjusted EBITDA and segment adjusted operating margin, also increased meaningfully over this period.

• GAAP Net Income is influenced by a number of factors and can include items that are one-time in nature and is not

exclusively used by investors to determine the long-term earnings power of the Company. As such, trends can vary

meaningfully between CAP and GAAP Net Income.

Board of Directors

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

standards of the NYSE and the applicable rules of the SEC. The Audit Committee is governed by a written charter, as

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 a t 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 2024 . Throughout the year, the Audit

Committee met with the Company’s independent registered public accounting firm, management and internal auditors, both

together and separately in closed sessions, to review accounting, auditing, internal controls and financial reporting matters.

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

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, 2024 and unaudited consolidated financial statements for the quarters ended

December 31, 2023 , March 31, 2024 , and June 30, 2024 ;

• 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;

Communications with Audit Committees, as modified or supplemented and the overall scope and plans for the

annual audit, the results of their examinations, their evaluation of the Company’s internal controls and the overall

quality of the Company’s financial reporting;

• received the written disclosures and letter from Ernst & Young LLP required by the applicable requirements of the

Public Company Accounting Oversight Board regarding Ernst & Young LLP’s communication with the Audit

Committee concerning independence, and discussed with Ernst & Young LLP its independence;

• monitored the reporting system implemented to provide an anonymous complaint reporting procedure;

• reviewed the scope of and overall plans for the annual audit and the internal audit program;

• reviewed new accounting standards applicable to the Company with the Company’s Chief Financial Officer, internal

audit department and Ernst & Young LLP;

• consulted with management and Ernst & Young LLP with respect to the Company’s processes for risk assessment

and risk mitigation;

processes for monitoring compliance with the law, Company policies and the Code of Business Conduct and

Ethics.

AECOM 72 2025 PROXY STATEMENT

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, 2024 . 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, 2024 , 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, 2025 and recommended that the Board submit this

appointment to the Company’s stockholders for ratification at the 2025 Annual Meeting.

AECOM A-1 2025 PROXY STATEMENT

Annex A

Reconciliation of Non-GAAP Items

Our proxy contains financial information calculated other than in accordance with U.S. generally accepted accounting

principles (“GAAP”). In particular, the Company believes that non-GAAP financial measures such as NSR segment

operating margin, 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 operating margin

to reflect segment operating performance of our Americas and International segments, excluding AECOM Capital and G&A.

We also use constant-currency, which is calculated by conforming the current period results to the comparable period

exchange rates, and 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.

AECOM , a corporation organized and existing under and by virtue of the General Corporation Law of the State of Delaware

(the “Corporation”), does hereby certify as follows:

FIRST : That the Board of Directors of the Corporation on November 21, 2024 adopted resolutions that declared it

advisable and in the best interests of the Corporation to amend the Amended and Restated Certificate of Incorporation of the

Corporation to limit the liability of officers in circumstances under Section 102(b)(7) of the Delaware General Corporation

Law (the “DGCL”).

SECOND : That, on February 28, 2025, the Corporation’s 2025 annual meeting of stockholders was duly called and

held upon notice in accordance with Section 222 of the DGCL at which meeting the necessary number of shares as required

by statute were voted in favor of the amendment to the Amended and Restated Certificate of Incorporation of the

Corporation to limit the liability of officers in limited circumstances under Section 102(b)(7) of the DGCL.

THIRD : That Article Sixth of the Amended and Restated Certificate of Incorporation of the Corporation be amended

and restated in its entirety so that, as amended, Article Sixth shall read as follows:

“SIXTH: The Board shall have power, without stockholder action, to make Bylaws for the Corporation and to amend, alter or

repeal any Bylaws.

The powers and authorities herein conferred upon the Board are in furtherance and not in limitation of those conferred by

the laws of the State of Delaware. In addition to the powers and authorities herein or by statute expressly conferred upon it,

the Board may exercise all such powers and do all such acts and things as may be exercised or done by the Corporation,

subject, nevertheless, to the provisions of the laws of the State of Delaware, of this Amended and Restated Certificate of

Incorporation and of the Bylaws of the Corporation.

To the full extent permitted by Section 102(b)(7) of the General Corporation Law of the State of Delaware, the personal

liability of a director or officer to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a

director or officer shall be eliminated; provided, however, that such personal liability shall not be eliminated hereby (i) for any

breach of the director’s or officer’s duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good

faith or which involve intentional misconduct or a knowing violation of law, (iii) for any director under Section 174 of the

General Corporation Law of the State of Delaware, (iv) for any director or officer for any transaction from which the director

or officer derived an improper personal benefit, (v) for any officer in any action by or in the right of the Corporation or (vi) for

any act or omission occurring prior to the date when this provision shall have become effective. Elimination of such personal

liability is not intended to eliminate or narrow any protection otherwise applicable to directors or officers.”

FOURTH : That the aforesaid amendment to the Amended and Restated Certificate of Incorporation of the

Corporation was duly adopted in accordance with the applicable provisions of Section 242 of the DGCL.

FIFTH : That all other provisions of the Amended and Restated Certificate of Incorporation of the Corporation shall

remain in full force and effect.
