CACI Reports Record Results for Its Fiscal 2012 First Quarter and Raises Fiscal 2012 Guidance

Pro forma net income increased 41.6 percent

Pro forma diluted EPS increased 47.5 percent

Pro forma operating income increased 40.3 percent

Revenue increased 10.8 percent; organic revenue increased 8.3 percent

Record funding orders and contract awards

ARLINGTON, Va.--(BUSINESS WIRE)--November 2, 2011--CACI International Inc (NYSE: CACI), a leading professional services and information technology solutions provider to the federal government, announced results today for its first fiscal quarter ended September 30, 2011.

We are pleased to report record first quarter Fiscal Year 2012 (FY12) revenue of $924.4 million, an increase of 10.8 percent from the first quarter of Fiscal Year 2011 (FY11). The revenue increase was driven primarily by organic revenue growth of 8.3 percent.

Pro Forma First Quarter Results

In FY10, we completed two domestic acquisitions with acquisition-related contingent consideration, or earn-outs, which represent potential additional purchase consideration based on the acquired company’s performance post-acquisition. The fair values of the expected earn-outs were recorded as liabilities on the balance sheet as of each acquisition date, and are re-measured each quarter, with any change in the fair values of the liabilities reflected in the income statement. In the first quarter of our FY12, the liabilities decreased $0.6 million, with a corresponding increase to operating income, due to reductions in the fair values of the earn-out liabilities. In the first quarter of FY11, the liabilities increased, and operating income decreased, by $1.4 million. To provide a comparison of our results excluding these earn-out adjustments, pro forma results for the first quarter of FY12 and FY11 are shown below.

Pro forma operating income grew 40.3 percent over the prior year period to $75.1 million, driven primarily by strong growth of 12.2 percent in direct labor. We also completed a large, one-time commercial product sale this quarter that generated $12.0 million in revenue and $6.1 million in net income. Pro forma net income for the first quarter of FY12 was a record $41.8 million, or $1.40 pro forma diluted earnings per share, an increase of 41.6 percent over pro forma net income of $29.5 million, or $0.95 pro forma diluted earnings per share, for the same period in FY11. Net cash provided by operations in the quarter was $56.1 million. (See Reconciliation of Operating Income, Net Income and Diluted Earnings Per Share to Pro Forma Amounts on page 12.)

CEO Commentary and Outlook

Paul Cofoni, CACI's President and CEO, said, “Our record performance in the first quarter of the fiscal year confirms CACI’s strategy to position our solutions and services in support of our client’s greatest challenges in national security. We are winning business in our strategic focus areas of defense, intelligence, homeland security, and IT modernization and government transformation, where we continue to see growth opportunities. Across our enterprise we are delivering operational excellence, and we are agile in responding with innovative solutions to current and emerging client needs.

“In 13 out of the last 15 quarters, we have delivered on our financial goals of mid- to high-single-digit organic revenue growth and double-digit earnings growth. This quarter we again achieved our financial goals with record results in revenue, operating income, and EPS, and received $1.6 billion in contract funding orders in the quarter – the highest in CACI's history. We also generated record operating cash flow in the quarter. Our over $2 billion of contract awards included $635 million of S3 awards focused primarily in the C4ISR-related area, and approximately $350 million in intelligence contracts.”

Mr. Cofoni added, “Our mergers and acquisition program is accelerating our momentum in the high-growth cyber arena, with our recent strategic acquisitions of Pangia Technologies and Paradigm Holdings. Pangia and Paradigm expand CACI’s capabilities for cyber forensics and secure network operations, providing our clients with unique capabilities to respond to national security threats. We also completed the acquisition of Advanced Programs Group, a leading provider of Oracle e-Business services, significantly expanding our capabilities in the business systems and government transformation market.

"We are raising our guidance for Fiscal Year 2012 based on continued strength in our operating performance; the addition of acquisitions in the cyber and business systems areas; and a large commercial product sale. Our record performance in this first quarter of our 50 ^th year in business provides a solid foundation and strong momentum for the rest of this fiscal year and beyond.”

Recent Strategic Mergers and Acquisitions

Our strategic mergers and acquisition program continues to be a critical part of our long-term growth strategy, adding established customer relationships and high demand capabilities to our existing portfolio of company capabilities. Since the beginning of our FY12, we have completed three strategic acquisitions that enhance our positions in high growth segments of our addressable market:

• We acquired Pangia Technologies, LLC, to expand our cybersecurity solutions with critical services in cyber intelligence and computer network defense for the Intelligence Community. Pangia’s expertise in threat analysis, intrusion detection engineering, and information system architecture services expands our capabilities to deliver secure information systems infrastructure and ensure secure computer network operations.
• The acquisition of Paradigm Holdings, Inc. brings us leading experts in the emerging field of cyber forensics and capabilities to monitor and protect critical information systems. Paradigm also expands our computer network defense customer base, adding new customers in the defense, intelligence and federal civilian customer space.
• On October 3, 2011, we completed the acquisition of Advanced Programs Group, LLC (APG), a leading provider of Oracle e-Business services in the federal market. APG is a leading provider of financial and asset management, procurement, and business solutions, enabling enhanced productivity with reduced costs. This acquisition significantly increases CACI's already strong capabilities in the government transformation market, expanding our customer presence in the federal civilian, defense, and intelligence communities.

Other First Quarter Highlights

• In August 2011, we repurchased four million shares of our stock under an accelerated share repurchase program.
• We released Cyber Threats to National Security: Keeping the Nation’s Industrial Base Safe from Cyber Threats, a report co-sponsored by the U.S. Naval Institute and the Center for Security Policy which publishes recommendations from the fifth symposium in the Asymmetric Threat series on cybersecurity.

Reconciliation of Total Revenue Growth and Organic Revenue Growth
(Unaudited)

We are presenting organic revenue growth to reflect the effect of acquisitions on total revenue growth. Revenue generated from the date a business is acquired through the first anniversary of that date is considered acquired revenue growth. All remaining revenue growth is considered organic. We believe that this non-GAAP financial measure provides investors with useful information to evaluate the growth rate of our core business. This non-GAAP measure should not be considered in isolation or as a substitute for performance measures prepared in accordance with GAAP.

Selected Financial Data (Continued)
Reconciliation of Net Income to Pro Forma Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) and to Pro Forma Adjusted Net Income
(Unaudited)

The Company views EBITDA, EBITDA margin, Adjusted Net Income and Diluted Adjusted Earnings Per Share as important indicators of performance, consistent with the manner in which management measures and forecasts the Company’s performance. EBITDA is a commonly used non-GAAP measure when comparing our results with those of other companies. We believe Adjusted Net Income is a significant driver of long-term value and is used by investors to measure our performance. This measure in particular assists readers in further understanding our results and trends from period-to-period by removing certain non-cash items that do not impact the cash flow performance of our business. We are presenting EBITDA, EBITDA margin, Adjusted Net Income and Diluted Adjusted Earnings Per Share on a pro forma basis, to remove the impact of the earn-out adjustments as we believe these pro forma measures are a better indicator of our ongoing, recurring operations. Pro forma EBITDA is defined by us as GAAP net income plus net interest expense, income taxes, and depreciation and amortization, and less the earn-out adjustment described on page 1. Pro forma EBITDA margin is pro forma EBITDA divided by revenue. Pro forma Adjusted Net Income is defined by us as GAAP net income plus stock-based compensation expense, depreciation and amortization, and amortization of financing costs, and less the earn-out adjustment described on page 1; net of related tax effects computed using an assumed marginal tax rate of 39.3 percent. Pro forma Diluted Adjusted Earnings Per Share is Pro forma Adjusted Net Income divided by diluted weighted-average shares, as reported. Pro forma EBITDA and Pro forma Adjusted Net Income as defined by us may not be computed in the same manner as similarly titled measures used by other companies. These non-GAAP measures should not be considered in isolation or as a substitute for performance measures prepared in accordance with GAAP.

Selected Financial Data (continued)
Reconciliation of Operating Income, Net Income and Diluted Earnings Per Share to Pro Forma Amounts
(Unaudited)

As described on page 1, the Company is presenting pro forma Operating Income, Net Income and Diluted Earnings per Share to present results excluding the impact of earn-out adjustments recorded during the three month periods ended September 30, 2011 and 2010. During its fiscal year ended June 30, 2010, the Company completed two domestic acquisitions with acquisition related contingent consideration, or earn-outs, which represent additional purchase consideration based on the acquired company's performance post-acquisition. The fair values of the expected earn-outs were recorded as liabilities on the balance sheet as of each acquisition date, and are remeasured each quarter, with any change in the fair value of the liabilities reflected in the income statement. During the three month period ended September 30, 2011, the estimated earn-out liability was reduced, resulting in an increase to net income. This increase to net income was recorded in the income statement as a reduction in indirect costs and selling expenses. During the three month period ended September 30, 2010, the estimated earn-out liability was increased, resulting in a decrease to net income. This decrease to net income was recorded in the income statement as an increase in indirect costs and selling expenses. The change in the earn-out liability in each period presented is reflected in the tables below as the "Earn-out adjustment." The Company believes that presenting the key measures of Operating Income, Net Income, and Diluted Earnings per Share without the impact of these changes on indirect costs and selling expenses provides readers a better indicator of our ongoing, recurring operations. These non-GAAP measures should not be considered in isolation or as a substitute for performance measures prepared in accordance with GAAP.
