Looking ahead, we made several announcements today that underscore our commitment to extending our competitive advantage and expanding our long-term earnings power. This includes our expectation to achieve a 20%+ margin run-rate by the end of fiscal 2028 as we advance our proprietary AECOM AI capabilities and growth accelerates in our higher-margin Advisory business. Importantly, the organization has never been stronger or better positioned to capitalize on these opportunities.” “As demand for critical infrastructure across our markets continues to grow, project size and complexity are also increasing, which creates new opportunities for our rapidly-growing Advisory practice,” said Lara Poloni, AECOM’s president. “The secular megatrends of global investments in infrastructure, in sustainability and resilience, and in meeting growing energy demand have accelerated. Amid this backdrop, our advantages of deep technical expertise, trusted client relationships, and a capacity and willingness to invest to advance our proprietary AECOM AI and Advisory capabilities separate us from the competition – both in our core industry and beyond.” 1 “Our fiscal 2025 results and raised long-term margin and adjusted EPS CAGR targets demonstrate our growing competitive advantage,” said Gaurav Kapoor, AECOM’s chief financial and operations officer. “We are focused on further leveraging our advantages. AI is creating new opportunities, including being able to scale our human and intellectual capital in more impactful ways, including expanding our operating leverage. As a result, we are confident in delivering on our new long-term financial targets.” Fourth Quarter and Full Year Fiscal 2025 Highlights: · Reflecting as reported GAAP performance from continuing operations, fourth quarter revenue increased 2% to $4.2 billion, operating income was effectively unchanged at $237 million, net income declined 22% to $132 million and diluted earnings per share decreased 21% to $0.99. For the full year, revenue was effectively unchanged at $16.1 billion, operating income increased 24% to $1.0 billion, net income increased 26% to $638 million and diluted earnings per share increased 29% to $4.79. · NSR 2 growth accelerated to 8% in the fourth quarter, driven by 9% growth in the Americas design business. · Earnings exceeded the mid-point of the Company’s previously-increased financial guidance. ‒ Fourth quarter adjusted 1 EBITDA 4 and adjusted 1 EPS increased by 13% and 7%, respectively § When adjusted for the previously-expected higher tax rate in the fourth quarter, adjusted 1 EPS would have increased by 18%. ‒ Full year adjusted 1 EBITDA 4 and adjusted 1 EPS increased by 10% and 16%, respectively, and set new full year records. · Delivered a record full year segment adjusted 1 operating margin 3 and exceeded the Company’s prior long-term 17%+ margin guidance five quarters ahead of its prior expectations. ‒ The full year segment adjusted operating margin 3 increased by 70 basis points to 16.5% and the adjusted 1 EBITDA margin 5 increased by 80 basis points to 16.8%, both of which set new full year records. ‒ The fourth quarter segment adjusted operating margin 3 increased by 40 basis points to 17.1% and the adjusted 1 EBITDA margin 5 increased by 80 basis points to 17.5%. · Operating cash flow of $822 million contributed to free cash flow 6 of $685 million for the full year. Backlog and Pipeline Update · Total backlog 7 increased by 4% and design backlog increased by 3%, both of which increased quarter-over-quarter to new all-time highs. ‒ Backlog increased in both the Americas and International design businesses. ‒ Design book-to-burn 8 in the fourth quarter was 1.1x, contributing to the 20 th consecutive quarter the Company has delivered a book-to-burn ratio in excess of 1.0. · The Company’s pipeline of opportunities in the design business increased by 13% year-over-year, reaching an all-time high for the sixth consecutive quarter driven by robust funding across all of its largest markets. ‒ Growth remains strongest in the earlier stages of the pipeline as new project formation continues to accelerate, reflective of growing global demand and funding for critical infrastructure. Capital Allocation Update · The Company returned nearly $500 million to shareholders in the fiscal year through repurchases and dividends. · The Board of Directors approved a 19% increase to the Company’s quarterly dividend to $0.31 per share. ‒ The Company has grown its per share dividend at a 20% CAGR since its initiation, delivering on its commitment to increase the value of its per share dividend by a double-digit percentage annually. ‒ The increased dividend as declared by the Board will be reflected in the Company’s next dividend payment on January 23, 2026, to stockholders of record on January 7, 2026. · Since the initiation of its repurchase program in September 2020, the Company has returned more than $3 billion of capital to shareholders through repurchases and dividends. · Subsequent to the fiscal fourth quarter end, the Company approved a plan to evaluate strategic alternatives for the Construction Management business, including a possible sale. – The decision to pursue strategic alternatives is consistent with the Company’s commitment to focus time and capital on its highest-returning and fastest-growing businesses and markets. – Beginning in the first quarter, the Construction Management business is expected to be classified as held for sale and reported in discontinued operations for GAAP reporting purposes. – The Company has retained Goldman Sachs & Co. LLC as financial advisor and Wachtell, Lipton, Rosen & Katz as legal advisor. Fiscal 2026 Financial Guidance AECOM is providing financial guidance for fiscal 2026 both with and without the Construction Management business. · The Company initiated guidance for the enterprise-wide business for fiscal 2026 with expectations for continued strong performance, including: ‒ Adjusted 1 EPS of between $5.65 and $5.85, reflecting a 9% increase at the mid-point over the prior year. 2 ‒ Adjusted 1 EBITDA 4 of between $1,265 million and $1,305 million, reflecting an increase of 7% at the mid-point over the prior year. ‒ Free cash flow 6 of approximately $400 million, which includes expectations for strong underlying cash flow. § Cash flow guidance also includes expected investments to execute on the Company’s announced restructuring to deliver key AI initiatives and efficiencies outlined at today’s 2025 Investor Day. § These investments are key drivers of the Company’s increased long-term margin and earnings targets, which would substantially lead the industry. · Beginning with the first quarter of fiscal 2026, the Company expects to report results for its continuing design and consulting business, which excludes the Construction Management business that is expected to be classified as held for sale and reported in discontinued operations. On this basis, the Company initiated the following fiscal 2026 guidance for: ‒ Organic NSR 2 growth of 6% to 8%, which excludes the expected impact of fewer working days in fiscal 2026 than in fiscal 2025. § NSR is expected to be between $7.2 and $7.4 billion, or approximately 5% growth at the mid-point. ‒ Adjusted 1 EBITDA 4 of between $1,180 million and $1,220 million. ‒ A segment adjusted operating margin 3 of 16.6% and an adjusted EBITDA margin 5 of 16.8% § Margins include accelerating investment to enable the continued development and deployment of AI and continue to expand the Company’s Advisory team. ‒ Adjusted 1 EPS of between $5.15 and $5.35. · Other assumptions incorporated into guidance: ‒ An average fully diluted share count of 133 million, which does not include any potential future benefits from capital allocation actions not yet taken, including potential repurchases. ‒ G&A of approximately $155 million. ‒ Depreciation of approximately $160 million. ‒ An adjusted effective tax rate of approximately 22 - 23% for the full year. ‒ Adjusted net interest expense of approximately $140 million. · See the Regulation G Information tables at the end of this release for a reconciliation of non-GAAP measures to the most directly comparable GAAP measures. Raised Long-Term Financial Targets As separately announced as part of its 2025 Investor Day, AECOM increased its long-term financial targets, highlighted by its expectation to deliver a 20%+ margin exit rate by fiscal 2028 and to grow adjusted EPS at a 15%+ CAGR from fiscal 2026 to fiscal 2029. In addition, the Company expects to deliver from fiscal 2026 to 2029 a 5 – 8% organic NSR CAGR, to convert at least 100% of adjusted net income to free cash flow cumulatively and continue to increase the per share value of its dividend by a double-digit percentage annually over the same period. Business Segments Americas Revenue in the fourth quarter was $3.2 billion, a 2% increase from the prior year. Full year revenue of $12.5 billion was effectively unchanged over the prior year. Net service revenue 2 in the fourth quarter was $1.2 billion, a 13% increase from the prior year. Full year net service revenue 2 was $4.6 billion, a 9% increase from the prior year.

The fourth quarter adjusted operating margin on net service revenue increased by 70 basis points to 20.4%. The full year adjusted operating margin on net service revenue increased by 90 basis points over the prior year to 19.8%, a new record that reflects the ongoing execution of initiatives to deliver expanding operating leverage, as well as strong execution and growth. International Revenue in the fourth quarter was $935 million, a 1% decrease from the prior year. Full year revenue was $3.6 billion, unchanged from the prior year. Net service revenue 2 in the fourth quarter was $769 million, effectively unchanged from the prior year. Full year net service revenue 2 was $3.0 billion, a 1% increase from the prior year.

The fourth quarter adjusted operating margin on net service revenue decreased by 50 basis points to 12.1%, primarily due to lower revenue in certain end markets. The full year adjusted operating margin on net service revenue remained unchanged over the prior year at 11.5%. 3 Balance Sheet As of September 30, 2025, AECOM had $1.6 billion of total cash and cash equivalents, $2.7 billion of total debt and $1.2 billion of net debt (total debt less cash and cash equivalents). Net leverage 9 was 0.8x. Tax Rate The effective tax rate was 28.1% in the fourth quarter and 22.3% in the full year. On an adjusted 1 basis, the effective tax rate was 29.0% in the fourth quarter and 24.3% in the full year, which was consistent with the Company’s guidance. The adjusted tax rate was derived by re-computing the quarterly effective tax rate on adjusted net income 10 . The adjusted tax expense differs from the GAAP tax expense based on the taxability or deductibility and tax rate applied to each of the adjustments.

Important factors that could cause our actual results, performance and achievements, or industry results to differ materially from estimates or projections contained in our forward-looking statements include, but are not limited to, the following: our business is cyclical and vulnerable to economic downturns and client spending reductions; government shutdowns or other funding circumstances that cause governmental agencies to modify, curtail or terminate our contracts; losses under fixed-price contracts; limited control over operations that run through our joint venture entities; liability for misconduct by our employees or consultants; failure to comply with laws or regulations applicable to our business; maintaining adequate surety and financial capacity; potential high leverage and inability to service our debt and guarantees; our capital allocation strategy, including ability to continue payment of dividends; exposure to political and economic risks in different countries, including tariffs, geopolitical events, and conflicts; currency exchange rate and interest fluctuations; retaining and recruiting key technical and management personnel; legal claims; inadequate insurance coverage; environmental law compliance and adequate nuclear indemnification; unexpected adjustments and cancellations related to our backlog; partners and third parties who may fail to satisfy their legal obligations; managing pension costs; AECOM Capital real estate development projects; cybersecurity issues, IT outages and data privacy; risks associated with the benefits and costs of the sale of our Management Services and self-perform at-risk civil infrastructure, power construction and oil and gas businesses, including the risk that any purchase adjustments from those transactions could be unfavorable and result in any future proceeds owed to us as part of the transactions could be lower than we expect; risks associated with strategic initiatives, including AI investments and potential acquisitions and divestitures; as well as other additional risks and factors that could cause actual results to differ materially from our forward-looking statements set forth in our reports filed with the Securities and Exchange Commission. Any forward-looking statements are made as of the date hereof. We do not intend, and undertake no obligation, to update any forward-looking statement. Non-GAAP Financial Information    This communication contains financial information calculated other than in accordance with U.S. generally accepted accounting principles (“GAAP”). The Company believes that non-GAAP financial measures such as adjusted EPS, adjusted EBITDA, adjusted EBITDA margin, adjusted net/operating income, segment adjusted operating margin, adjusted tax rate, net service revenue and free cash flow provide a meaningful perspective on its business results as the Company utilizes this information to evaluate and manage the business. We use adjusted operating income, adjusted net income, adjusted EBITDA, adjusted EBITDA margin, 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 net service revenue (NSR) to exclude pass-through subcontractor costs from revenue to provide investors with a better understanding of our operational performance. We present segment adjusted operating margin to reflect segment operating performance of our Americas and International segments, excluding AECOM Capital.  We present adjusted tax rate to reflect the tax rate on adjusted earnings. We also use constant-currency growth rates where appropriate, which are calculated by conforming the current period results to the comparable period exchange rates. 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. A reconciliation of these non-GAAP measures is found in the Regulation G Information tables at the back of this communication. The Company is unable to reconcile certain of its non-GAAP financial guidance and long-term financial targets due to uncertainties in these non-operating items as well as other adjustments to net income. The Company is unable to provide a reconciliation of its guidance for NSR to GAAP revenue because it is unable to predict with reasonable certainty its pass-through revenue. In addition, the Company is unable to provide a reconciliation of its guidance for financial metrics excluding the Construction Management business due to uncertainties in these non-operating items as well as other adjustments to these measures. 5 AECOM Consolidated Statements of Income (unaudited - in thousands, except per share data) Three Months Ended Twelve Months Ended September 30, 2025
