First Quarter 2019 Accomplishments:

·Organic(3) revenue increased by 5% over the prior-year quarter, highlighted by double-digit growth in the Company’s higher-margin Americas design business and Management Services segment.

·Total backlog increased by 22%(2) year-over-year to a new all-time high of $59.5 billion.

·Wins in the quarter were $11.0 billion, which included the contract for the $7 billion Terminal One project at JFK airport in New York, a 1.3 book-to-burn ratio(4) in the Management Services segment.

·Solid execution across the Company’s portfolio of projects resulted in adjusted earnings that were ahead of expectations, including 16% year-over-year adjusted EBITDA growth.

·The Company continued to execute on its capital allocation priorities, including additional share repurchases in the quarter and in January, bringing total share repurchases to $210 million under its $1 billion Board authorized repurchase plan.

Update on Strategic Value Creation Actions:

·AECOM has completed nearly all of the actions necessary to achieve its expected $225 million of annual G&A savings, which are expected to generate $85 million of realized savings in fiscal 2019, resulting in at least 110 basis points of margin improvement in the DCS segment this year and additional expected benefits in fiscal 2020 and beyond.

·The Company continues to make progress on de-risking its business; in addition to the decisions made in fiscal 2018, including the planned exit from the fixed-price combined-cycle gas power plant construction market and non-core Oil & Gas markets, it is no longer pursuing international at-risk construction opportunities, has completed the spin-out of the infrastructure financing arm of AECOM Capital, and is reviewing its remaining at-risk construction exposure.

·The Company has completed approximately 25% of its plan to exit at least 30 countries as part of a strategy to simplify its operating structure and to hone management’s focus on the most profitable growth opportunities.

·Collectively, these actions position the Company to capitalize on its record backlog by focusing resources on higher-margin and lower-risk professional services businesses where its competitive advantages are greatest.

“Continued overall growth in the DCS and MS segments, new records for wins and backlog, and adjusted earnings that surpassed our expectations resulted in a strong start to the year, and we are firmly on track to achieve our full-year guidance, including expectations for double-digit adjusted EBITDA growth,” said Michael S. Burke, AECOM’s chairman and chief executive officer. “Importantly, we have taken and will continue to take decisive actions to maximize the profitability of our record backlog. With the positive momentum in the business, including several substantial wins already in the second quarter, and the expected benefits from our strategic actions, we are committed to achieving our five-year financial targets from fiscal 2018 through fiscal 2022, including a 5% revenue CAGR, a 9% adjusted EBITDA CAGR, a 12%-15% adjusted EPS CAGR and at least $3.5 billion of cumulative free cash flow.”

“The several records in the quarter create a strong foundation for expected profitable growth,” said W. Troy Rudd, AECOM’s chief financial officer. “Though cash flow was below our expectations primarily due to the partial U.S. government shutdown, we expect to recover this cash flow as the year progresses and expect to achieve our full year free cash flow guidance of $600 to $800 million. Importantly, we continue to execute on our capital allocation policy, as evidenced by $210 million of repurchases to-date under our $1 billion Board authorization.”

Wins and Backlog

Wins were $11.0 billion, which set a new record for the Company, and resulted in a book-to-burn ratio(4) of 2.0. Wins included strength across the business, highlighted by the award for the new $7 billion Terminal One at JFK, and a 1.3 book-to-burn ratio in the MS segment. Total backlog increased by 22%(2) over the prior year to $59.5 billion, which also set a new record.

Business Segments

Design & Consulting Services (DCS)

The DCS segment delivers planning, consulting, architectural and engineering design services to commercial and government clients worldwide in markets such as transportation, facilities, environmental, energy, water and government.

Revenue in the first quarter was $2.0 billion and increased by 5%. Constant-currency organic(3) revenue increased by 7%. This performance included 12% organic growth in the Americas, which was driven by the transportation and water markets, including a positive contribution from the storm recovery efforts in the Southeastern U.S. and Caribbean.

Operating income was $120 million compared to $85 million in the year-ago period. On an adjusted basis, operating income(1) was $126 million compared to $92 million in the year-ago period. Operating income increased over the prior year period due to strong performance in the Americas and Asia-Pacific regions.

Construction Services (CS)

The CS segment provides construction services for energy, sports, commercial, industrial, and public and private infrastructure clients.

Revenue in the first quarter was $2.0 billion and decreased by 5%. Constant-currency organic(3) revenue declined by 2%, due to a decline in Building Construction and a reduced contribution from Power, which were consistent with prior expectations.

Operating income was $11 million compared to $40 million in the year-ago period. On an adjusted basis, operating income(1) was $31 million compared to $51 million in the year-ago period. The decline in operating income reflects a lower contribution from Power. Importantly, execution of the Alliant Riverside combined-cycle gas power plant is on schedule and on budget.

Management Services (MS)

The MS segment provides program and facilities management and maintenance, training, logistics, consulting, technical assistance and systems-integration services and information technology services, primarily for agencies of the U.S. government, national governments around the world and commercial customers.

Revenue in the first quarter was $989 million. Revenue and organic(3) revenue growth accelerated in the quarter to 17%, reflecting near record levels of backlog and strong funding for the U.S. Departments of Defense and Energy clients.

Operating income was $51 million compared to $40 million in the year-ago period. On an adjusted basis, operating income(1) was $61 million compared to $50 million in the year-ago period. The increase in operating income represents strong execution on the segment’s near record backlog, and favorable end market trends.

AECOM Capital (ACAP)

The ACAP segment invests in and develops real estate projects. Revenue in the first quarter was $4 million and operating loss was $0.3 million. After the quarter closed, ACAP completed the sale of a property that resulted in an approximately 40% IRR and an approximately $10 million gain on its investment.

Tax Rate

The effective tax rate in the first quarter was (106.7%), which included a benefit from the release of a $38 million valuation allowance. On an adjusted basis, the effective tax rate was 24.3%. The adjusted tax rate was derived by re-computing the annual effective tax rate on earnings from adjusted net income.(5) 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.

2

Cash Flow

Operating cash flow for the first quarter was ($200) million and free cash flow(6) was ($222) million. Cash flow was below expectations due primarily to slower collections from the U.S. Federal government as a result of the shutdown, which negatively impacted cash flow by approximately $200 million. The Company remains on track with its annual free cash flow guidance of $600 million to $800 million for fiscal 2019.

Balance Sheet and Capital Allocation

As of December 31, 2018, AECOM had $838 million of total cash and cash equivalents, $3.1 billion of net debt and $1.01 billion in unused capacity under its $1.35 billion revolving credit facility. During the quarter, the Company repurchased $30 million of stock and, including additional repurchases completed in January, has repurchased 6.7 million shares under its $1 billion Board authorization.

Financial Outlook and Impacts of Strategic Actions

AECOM’s fiscal 2019 financial guidance is as follows:

	Fiscal Year 2019 Outlook
Adjusted EBITDA(1)	$920 - $960 million
Adjusted EPS(1)	$2.60 – $2.90
Free Cash Flow(2)	$600 – $800 million
Adjusted Interest Expense (excluding amortization of deferred financing fees)	$200 million
Amortization(7)	$88 million
Full-Year Share Count	161 million
Effective Tax Rate for Adjusted Earnings(5)	~25%
Capital Expenditures(8)	~$120 million

AECOM continues to expect to incur restructuring costs of between $80 and $90 million in fiscal 2019, nearly all of which have been actioned. The Company continues to expect total cash costs for the restructuring of between $60 and $70 million.

Also included in the Company’s fiscal 2019 guidance is approximately $13 million of EBITDA from AECOM Capital contributions.

Adoption of New Revenue Recognition Standard:

Beginning with its first quarter 2019 financial results, the Company has adopted the new standard for revenue recognition (ASC 606). Adoption of the new standard did not have a material impact on the Company’s financial statements, and the impact to first quarter financial performance and fiscal year 2019 financial guidance is immaterial.

All statements in this press release other than statements of historical fact are “forward-looking statements” for purposes of federal and state securities laws, including any projections of earnings, revenue, cost savings, profitability, cash flows, tax rate, share count, stock repurchases, interest expense, capital expenditures, amortization of intangible assets and financial fees, or other financial items, any statements of the plans, strategies and objectives for future operations, profitability, strategic value creation, risk profile and investment strategies and any statements regarding future economic conditions or performance. Although we believe that the expectations reflected in our forward-looking statements are reasonable, actual results could differ materially from those projected or assumed in any of our forward-looking statements.

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; long-term government contracts and subject to uncertainties related to government contract appropriations; government shutdowns; governmental agencies may modify, curtail or terminate our contracts; government contracts are subject to audits and adjustments of contractual terms; losses under fixed-price contracts; limited control over operations 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; high leveraged and potential inability to service our debt and guarantees; exposure to Brexit; exposure to political and economic risks in different countries; currency exchange rate 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; AECOM Capital real estate development projects; managing pension cost; cybersecurity issues and IT outages; 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. We do not intend, and undertake no obligation, to update any forward-looking statement.

This press release contains financial information calculated other than in accordance with U.S. generally accepted accounting principles (“GAAP”). In particular, the Company believes that non-GAAP financial measures such as adjusted EPS, adjusted EBITDA, adjusted operating income, adjusted tax rate, adjusted interest expense, organic revenue, and free cash flow also provide a meaningful perspective on its business results as the Company utilizes this information to evaluate and manage the business. We use adjusted EBITDA, EPS and operating income to exclude the impact of non-operating items, such as amortization expense, taxes, acquisition and integration expenses, and non-core operating losses. We use free cash flow to represent the cash generated after capital expenditures to maintain our business. Our non-GAAP disclosure has limitations as an analytical tool, should not be viewed as a substitute for financial information determined in accordance with GAAP, and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP, nor is it necessarily comparable to non-GAAP performance measures that may be presented by other companies. A reconciliation of these non-GAAP measures is found in the Regulation G Information tables at the back of this release.

We present constant currency information to help assess how our underlying businesses performed excluding the effect of foreign currency rate fluctuations. We provide this non-GAAP financial information to aid investors in better understanding our international operational performance.

When we provide our long term projections for organic revenue growth, adjusted EBITDA, adjusted EPS growth, and free cash flow on a forward-looking basis, the closest corresponding GAAP measure and a reconciliation of the differences between the non-GAAP expectation and the corresponding GAAP measure generally is not available without unreasonable effort due to length of the forecasted period and potential high variability, complexity and low visibility as to items that would be excluded from the GAAP measure in the relevant future period.
