LOS ANGELES (May 10, 2016) — AECOM (NYSE: ACM), a premier, fully integrated global infrastructure firm, today reported second-quarter revenue of $4.4 billion. Net income3 and earnings per share3 were $41.8 million and $0.27 in the second quarter, respectively. On an adjusted basis, diluted earnings per share1 was $0.87.

Note: All comparisons are year over year unless otherwise noted.

“We made steady progress against our key strategic and financial objectives, most notably the return to growth in the Americas, continued strong cash generation, and additional debt reduction,” said Michael S. Burke, AECOM’s chairman and chief executive officer. “We have a vastly diverse business and remain confident in our ability to capitalize on the momentum we see building across our end markets.”

“Our performance in the second quarter reflects the benefits of our diverse mix of geographies and end markets,” said Stephen M. Kadenacy, AECOM’s president. “From this diversity we are able to generate consistent results and deliver value for our shareholders.”

Wins and Backlog
Wins in the quarter of $2.7 billion were driven primarily by the Americas business within the Design & Consulting Services segment. The book-to-burn ratio4 was 0.6. Additionally, the Company won projects with a total construction value of $1.1 billion, primarily in Building Construction within the Construction Services segment. However, due to the accounting for unconsolidated joint ventures and projects executed on an agency basis, these projects are not reflected in backlog. The Company’s total backlog of $38.6 billion decreased 4% from the prior quarter. Including the $1.1 billion of construction value not reflected in our backlog, wins were $3.8 billion and backlog would have been $39.7 billion.

Business Segments

In addition to providing consolidated financial results, AECOM reports separate financial information for its three segments: Design & Consulting Services, Construction Services and Management Services.

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 second quarter was $2.0 billion. Constant-currency5 organic revenue was down 0.6%, with growth returning in the Americas. Adjusted operating income6 increased to $140 million compared to $108 million in the year ago period, primarily due to operating efficiencies achieved through synergy savings and improving trends in the Americas.

Construction Services (CS)

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

Revenue in the second quarter was $1.5 billion. Constant-currency5 organic revenue decreased 1.3%, as strong growth in the Building Construction business was offset by ongoing pressure in the oil and gas market. Adjusted operating income7 was $19 million compared to $26 million in the year ago period. The decline was driven by pressure in the oil and gas market, which was partially offset by a strong contribution from the stadium construction business.

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 second quarter was $869 million. Organic revenue increased 5%. Adjusted operating income7 was $138 million compared to $105 million in the year ago period. Revenue and adjusted operating income7 include a significant positive impact from the accelerated recovery of a government pension entitlement resulting from the harmonization of our benefit programs. The impact to earnings per share from this item is $0.14 in fiscal 2016, with the anticipated cash benefit likely in fiscal 2017.

Tax Rate

The effective tax rate in the second quarter was 26% and was arrived at by recomputing the annual effective tax by excluding the tax impacts on the effective tax rate of the adjustments8 made to GAAP net (loss) income, which was then applied to the adjusted net (loss) income.  The adjusted tax expense differs from the GAAP tax expense based on the deductibility and tax rate applied to each of the adjustments.

Cash Flow

Free cash flow2 for the second quarter was $83 million; on track with annual free cash flow target of $600 million to $800 million for fiscal years 2016 and 2017.

Balance Sheet

As of March 31, 2016, AECOM had $670 million of cash and cash equivalents, $4.5 billion of debt and $910 million in unused capacity under its $1.05 billion revolving credit facility.

Financial Outlook

AECOM is reiterating adjusted EPS1 guidance for fiscal year 2016 of $3.00 to $3.40, which assumes an expected contribution from the monetization of a portion of AECOM Capital investments.

The Company expects to exit fiscal 2016 at a synergy savings run-rate of $275 million and to incur approximately $200 million of acquisition and integration expenses during the fiscal year. In total, the Company is on track to achieve its $325 million run-rate synergy savings target by the end of fiscal 2017.

In addition, the Company expects fiscal 2016 full-year interest expense, excluding acquisition-related amortization, of approximately $210 million and a full-year share count of 156 million.

The Company also expects an adjusted effective tax rate8 of approximately 27%.

Fiscal year 2016 capital expenditures9 are on track to be approximately $150 million. The Company expects depreciation of approximately $165 million and the amortization of intangible assets10 of approximately $200 million.

Forward-Looking Statements: 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, cash flows, tax rate, share count, interest expense, amortization of intangible assets, AECOM Capital contributions, synergy costs, acquisition and integration costs, or other financial items; any statements of the plans, strategies and objectives for future operations; 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:  demand for our services is cyclical; uncertainties related to government contract appropriations; 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; misconduct by our employees or consultants or our failure to comply with laws or regulations applicable to our business; our leveraged position and ability to service our debt; exposure to legal, political and economic risks in different countries as well as currency exchange rate fluctuations; the failure to retain and recruit key technical and management personnel; our insurance policies may not provide adequate coverage; unexpected adjustments and cancellations related to our backlog; dependence on third party contractors who fail to satisfy their obligations; systems and information technology interruption; and changing client preferences/demands, fiscal positions and payment patterns. Additional factors that could cause actual results to differ materially from our forward-looking statements are 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 operating income, adjusted tax rate, adjusted EBITDA, 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 are also providing additional non-GAAP financial measures to reflect the impact of past acquisitions, including acquisition and integration expenses. 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 press release tables.
