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

“We delivered strong organic revenue growth and made substantial progress on our integration priorities,” said Michael S. Burke, AECOM’s chairman and chief executive officer. “The solid results we delivered today reflect our global leadership position and the complementary skill sets we have integrated over time. We are on track with our vision to become the world’s premier fully integrated infrastructure services firm, and our addressable market opportunity has never been greater.”

New Wins and Backlog
New wins in the quarter of $4.6 billion were driven by growth in the company’s Europe, Middle East, Africa, and India region and its building construction business. After adjusting for acquisitions, total backlog grew six percent organically. The company’s book-to-burn ratio6 was 1x for the quarter, with total backlog at March 31, 2015, of $40.7 billion.

Business Segments

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

Design & Consulting Services (DCS)

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

Revenue of $2 billion in the quarter increased 56 percent. Constant-currency organic revenue increased one percent1. Adjusted operating income7 was $108 million, an increase of 34 percent.

Construction Services (CS)

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

Revenue in the quarter was $1.6 billion. On an organic basis, revenue increased 62 percent. Adjusted operating income7 was $26 million. Results were favorably impacted by strong performance in the building construction business.

Management Services (MS)

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

Revenue increased 266 percent to $829 million in the quarter. Adjusted operating income7 was $105 million, benefiting from the strength of the acquired operations and strong execution.

Tax Rate

Inclusive of the non-controlling interest deduction — and excluding acquisition and integration related expenses, financing charges in interest expense, amortization of intangible assets, and unusual discrete items — the effective tax rate was 29.3 percent.

Impact of Acquisition-Related Accounting Items

AECOM continues to evaluate the accounting impact of recently completed acquisitions. The net impact of acquisition-related accounting items did not have a significant impact on second-quarter adjusted earnings per share. In conjunction with the evaluation, the company retrospectively adjusted results for the fiscal first quarter ended Dec. 31, 2014, to include the adjustment to the margin fair value liability, included in billings in excess of costs on uncompleted contracts. As a result, the firm’s first-quarter adjusted earnings per share increased by $0.09 to $0.80. For the remainder of the year, recognition in income from the margin fair value liability is anticipated to result in a $0.21 favorable impact to adjusted earnings per share. The company’s updated 2015 adjusted earnings per share guidance reflect these impacts.

Cash Flow

Cash flow from operations for the quarter was $50 million. Free cash flow3 was $19 million in the quarter. In the first six months of the fiscal year, AECOM generated free cash flow of $277 million.

Balance Sheet

As of March 31, 2015, AECOM had $613 million of total cash and cash equivalents, $4.87 billion of debt and $952 million in unused capacity under the $1.05-billion revolving credit facility.

Fiscal 2015 Outlook

AECOM is increasing adjusted EPS2 guidance for fiscal year 2015 to $3.15 to $3.55. The increase reflects business trends that are consistent with the firm’s prior outlook and includes the expected $0.30 net positive impact to EPS from acquisition-related accounting items. The mid-point of the range assumes approximately $110 million of realized cost-synergy benefits from the URS combination.

In addition, the company continues to expect full-year interest expense of approximately $220 million, capital expenditures8 of approximately $160 million, depreciation of approximately $210 million, a tax rate9 of 30 percent, and a full-year share count of 151 million shares.

Adjusted EPS guidance for fiscal year 2015 excludes the amortization of intangible assets, financing charges in interest expense, and acquisition and integration expenses. In total, these items are expected to result in a pre-tax expense of approximately $810 million10 for the year.

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, amortization, 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 forward-looking statements include: uncertainties related to global economic conditions and funding, audits, modifications and termination of long-term government contracts; 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; failure to successfully execute our merger and acquisition strategy; the failure to retain and recruit key technical and management personnel; and unexpected adjustments and cancellations related to our backlog. 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 adjusted EPS, adjusted operating income, adjusted tax rate, organic and constant currency 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 the URS acquisition. This 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 the company’s results as reported under GAAP, nor is it necessarily comparable to non-GAAP performance measures that may be presented by other companies.
