PART I

Item 1. Business

Background

CACI International Inc was organized as a Delaware corporation under the name “CACI WORLDWIDE, INC.” on October 8, 1985. By a merger on June 2, 1986, the registrant became the parent of CACI, Inc., a Delaware corporation, and CACI N.V., a Netherlands corporation. Effective April 16, 2001, CACI, Inc. was merged into its wholly-owned subsidiary, CACI, INC.-FEDERAL, such that the registrant is now the corporate parent of CACI, INC.-FEDERAL, a Delaware corporation, and CACI N.V., a Netherlands corporation. The registrant is a holding company and its operations are conducted through subsidiaries, which are located in the U.S. and Europe, and a joint venture which is controlled by the registrant.

Overview

CACI founded its business in 1962 in simulation technology. With revenue for the year ended June 30, 2013 (FY2013) of $3.7 billion, we serve clients in the U.S. federal government and commercial markets, primarily throughout North America and internationally on behalf of U.S. customers, as well as in the United Kingdom (U.K.) and the Netherlands. We deliver information solutions and services to our clients. Through our service offerings, we provide comprehensive and practical solutions by adapting emerging technologies and continually evolving legacy strengths. As a result of our diverse capabilities and client mission understanding, many of our client relationships have existed for ten years or more.

Our reliable and high-quality solutions and services have enabled us to successfully compete for and win repeat business, sustain long-term client relationships and compete effectively for new clients and new contracts. We seek competitive business opportunities and have designed our operations to support major programs through centralized business development and business alliances. We have structured our business development organization to respond to the competitive marketplace, particularly within the federal government, and support that activity with full-time marketing, sales, communications, and proposal development specialists.

Our primary customers are agencies of the U.S. government. Our information solutions and services are primarily targeted to the areas of defense, intelligence, homeland security and information technology (IT) modernization in support of national security missions and government transformation. The demand for our services, in large measure, is created by the increasingly complex network, systems and information environments in which governments and businesses operate, and by the need to stay current with emerging technology while increasing productivity and, ultimately, improving performance.

Spending by the U.S. government with contractors who provide services to the Department of Defense (DoD), is being negatively impacted by the country’s fiscal shortfall. The Budget Control Act of 2011 (the Budget Act) established limits on discretionary spending, which will reduce planned defense spending by a minimum of $487 billion over a 10 year period that began with the government’s fiscal year ended September 30, 2012. In addition, the Budget Act included a sequester mechanism that imposed additional defense cuts of $500

billion, or approximately 9 percent, over nine years starting in the government’s fiscal year ending September 30, 2013, if the Congress did not identify a means to reduce the U.S. deficit by $1.2 trillion. Because these means were not identified, the sequester mechanism took effect on March 1, 2013. In light of the Budget Act and deficit reduction pressures, it is likely that discretionary spending by the federal government will remain constrained for a number of years.

The sequester mechanism, if left unmodified, along with other pressures on government spending, are negatively impacting our business and could have further negative impacts on us in the future. We may experience disruption of existing programs, delays in contract awards, and other actions, including partial or complete contract terminations.

During our FY2013, we took steps to make sure our cost structure is in line with our expectations of future business opportunities given the challenging environment for companies in our industry. We believe we are well positioned to win new business in the market areas we focus on, where the government is expected to continue to spend while constrained by sequestration.

At June 30, 2013, we had approximately 14,900 employees.

Domestic Operations

Our domestic operations account for 100 percent of our U.S. government revenue and 29.2 percent of our commercial revenue. Some of the contracts performed by our domestic operations involve assignment of employees to international locations in support of our federal government clients. At June 30, 2013, approximately 800 employees were on assignments in international locations. We provide our services and solutions to our domestic clients in the following market areas:

International Operations

Our international operations are conducted primarily through our operating subsidiaries in Europe, CACI Limited and CACI BV, and account for substantially all revenue generated from international clients and 70.8 percent of our commercial revenue. CACI’s European operations are headquartered in London, England, and operate primarily in our business systems and enterprise IT market areas.

Our international service offerings deliver a wide range of IT professional services and proprietary products to government and private organizations. Our international operations are engaged in the provision of services for health, education and the social care of children. We also provide network design and management services covering large scale voice and data networks for telcom service providers and corporate enterprises. Our services also include the provision of consulting and proprietary data and software products to enable our clients to find, retain and grow profitable customers through our understanding of consumer characteristics and behavior.

Competition

We operate in a highly competitive industry that includes many firms, some of which are larger in size and have greater financial resources than we do. We obtain much of our business on the basis of proposals submitted in response to requests from potential and current customers, who may also receive proposals from other firms. Additionally, we face indirect competition from certain government agencies that perform services for

themselves similar to those marketed by us. We know of no single competitor that is dominant in our fields of technology. We have a relatively small share of the available worldwide market for our solutions and services and intend to achieve growth and increasing market share both organically and through strategic acquisitions.

Strengths and Strategy

We offer substantially our entire range of solutions and services and proprietary products to defense, intelligence and civilian agencies of the U.S. government. Our work for U.S. government agencies may combine a wide range of skills drawn from our solutions, services and product offerings. We also contract through our international operations to supply solutions, services and/or products to governments of other nations. As with other government contractors, our business is subject to government client funding decisions and actions that are beyond our control.

Although we are a supplier of proprietary computer-based technology products and marketing systems products, we are not primarily focused on being a software product developer-distributor (see discussion following under “Patents, Trademarks, Trade Secrets and Licenses”).

Our international commercial client base consists primarily of large enterprises in the U.K. This market is the primary target of our proprietary marketing systems software, and database products and consultancy services. Commercial bids are frequently negotiated as to terms and conditions for schedule, specifications, delivery and payment.

In order to effectively perform on our existing client contracts and secure new client contracts within the U.S. government, we must maintain expert knowledge of agency policies, operations and challenges. We combine this comprehensive knowledge with significant expertise in the design, integration, development and implementation of advanced information solutions and services. This capability provides us with opportunities either to compete directly for, or to support other bidders in competition for, multi-million dollar and multi-year award contracts from the U.S. government.

We have strategic business relationships with a number of companies associated with the information technology industry. These strategic partners have business objectives compatible with ours and offer products and services that complement ours. We intend to continue development of these kinds of relationships wherever they support our growth objectives.

Our marketing and new business development is conducted by many of our officers and managers including the Chief Executive Officer, executive officers, vice presidents and division managers. We employ marketing professionals who identify and qualify major contract opportunities, primarily in the federal government market.

Much of our business is won through submission of formal competitive bids. Government and commercial clients typically base their decisions regarding contract awards on their assessment of the quality of past performance, responsiveness to proposal requirements, price, and other factors. The terms, conditions and form of contract of government bids, however, are in most cases specified by the client. In situations in which the client-imposed contract type and/or terms appear to expose us to inappropriate risk or do not offer us a sufficient financial return, we may seek alternate arrangements or opt not to bid for the work. Essentially all contracts with the U.S. government, and many contracts with other government entities, permit the government client to terminate the contract at any time for the convenience of the government or for default by the contractor. Although we operate under the risk that such terminations may occur and have a material impact on operations, such terminations have been rare and, generally, have not materially affected operations.

Our contracts and subcontracts are composed of a wide range of contract types, including firm fixed-price, cost reimbursement, time-and-materials (T&M), indefinite delivery/indefinite quantity (IDIQ) and government wide acquisition contracts (known as GWACS) such as General Services Administration (GSA) schedule contracts. By company policy, significant fixed-price contracts require the approval of at least two of our senior officers.

At any one time, we may have several thousand separate active contracts and/or task orders. In FY2013, the ten top revenue-producing contracts, many of which consist of many task orders, accounted for 40.7 percent of our revenue, or $1.5 billion.

In FY2013, 94.4 percent of our revenue came from U.S. government prime contracts or subcontracts consisting of 74.3 percent from DoD contracts and 20.1 percent from U.S. government civilian agency clients.

Industry Trends

The federal government is a large and sophisticated user of information technology. The nation’s expenditures on military, homeland security, and intelligence operations are substantially larger than those of any of its allies or adversaries. Budgets for these operations have nearly doubled since the terrorist attacks in 2001. We believe that the following trends will impact the federal government’s future spending on the types of services we provide:

We continue to expect to see a steady stream of funding for transformational activities that yield results in a shorter timeframe to maximize investments with more stable and predictable information system outcomes. As the amount of data and information grows, and persistent threats to our national security continue, the demands for applications will grow as well, putting a higher value on faster and more efficient/effective technologies. We expect this demand to result in an increasing need for rapid deployment of cyber solutions, cloud computing, and mobile applications. An additional area of cyber emphasis is the security of the supply chain. While technology provides part of the answer, the integration of processes and personnel using forward-looking systems and sound architectures is more likely to provide cost savings and performance efficiencies.

Recent Significant Acquisitions

During the past three fiscal years, we completed a total of eleven acquisitions, eight in the U.S. and three supporting our international operations, including:

Seasonal Nature of Business

Our business in general is not seasonal, although the summer and holiday seasons affect our revenue because of the impact of holidays and vacations on our labor and on product and service sales by our international operations. Variations in our business also may occur at the expiration of major contracts until such contracts are renewed or new business obtained.

The U.S. government’s fiscal year ends on September 30 of each year. It is not uncommon for government agencies to award extra tasks or complete other contract actions in the weeks before the end of a fiscal year in order to avoid the loss of unexpended funds. Moreover, in years when the U.S. government does not complete the budget process for the next fiscal year before the end of September, government operations whose appropriations legislation has not been signed into law are funded under a continuing resolution that authorizes them to continue to operate, but traditionally does not authorize new spending initiatives.

CACI Employment and Benefits

Our employees are our most valuable resource. We are in continuing competition for highly skilled professionals in virtually all of our business areas. The success and growth of our business is significantly correlated with our ability to recruit, train, promote and retain high quality people at all levels of the organization. For these reasons, we endeavor to maintain competitive salary structures, incentive compensation programs, fringe benefits, opportunities for growth, and individual recognition and award programs. Fringe benefits are generally consistent across our subsidiaries, and include paid vacations, sick leave and holidays; medical, dental, disability and life insurance; tuition reimbursement for job-related education and training; and other benefits under various retirement savings and stock purchase plans.

We have published policies that set high standards for the conduct of our business. We require all of our employees, independent contractors working on client engagements, officers, and directors annually to execute and affirm to the code of ethics applicable to their activities. In addition, we require annual ethics and compliance training for all of our employees to provide them with the knowledge necessary to maintain our high standards of ethics and compliance.

Patents, Trademarks, Trade Secrets and Licenses

We own 11 patents and patent applications in the United States. While we believe our patents are valid, we do not consider that our business is dependent on patent protection in any material way. We claim copyright, trademark and other proprietary rights in a variety of intellectual property, including each of our proprietary computer software and data products and the related documentation. We presently own 22 registered trademarks and service marks and applications in the U.S. and 32 registered trademarks and service marks in other countries, primarily the U.K. All of our registered trademarks and service marks may be renewed indefinitely. In addition, we assert copyrights in essentially all of our electronic and hard copy publications, proprietary software and data products, which rights can be maintained for up to 75 years. Because most of our business involves providing services to government entities, our operations generally are not substantially dependent upon obtaining and/or maintaining copyright or trademark protections, although our operations make use of such protections and benefit from them as discriminators in competition. We are also a party to agreements that give us the right to distribute computer software, data and other products owned by other companies, and to receive income from such distribution. As a systems integrator, it is important that we maintain access to software, data and products supplied by such third parties, but we generally have experienced little difficulty in doing so. The durations of such agreements vary according to the terms of the agreements themselves.

We maintain a number of trade secrets that contribute to our success and competitive distinction and endeavor to accord such trade secrets protection adequate to ensure their continuing availability to us. From time to time, we are required to assert our rights against former employees or other third parties who attempt to misappropriate our trade secrets and confidential information for their own personal or professional gain. We take such matters seriously and pursue claims against such individuals to the extent necessary to adequately protect our rights. While retaining protection of our trade secrets and vital confidential information is important, we are not materially dependent on maintenance of a specific trade secret.

Backlog

Our total backlog as of June 30, 2013, which consists primarily of contracts with the U.S. government, was $6.9 billion, of which $1.7 billion was for funded orders. Total backlog as of June 30, 2012 was $7.2 billion. We presently anticipate, based on current revenue projections, that the majority of the funded backlog as of June 30, 2013 will result in revenue during the fiscal year ending June 30, 2014.

Our backlog represents the aggregate contract revenue we estimate will be earned over the remaining life of our contracts. We include in estimated remaining contract value only the contract revenue we expect to earn over the remaining term of the contract, even in cases where more than one company is awarded work under a given contract. Funded backlog is based upon amounts appropriated by a customer for payment for goods and services and as the U.S. government operates under annual appropriations, agencies of the U.S. government generally fund contracts on an incremental basis. As a result, the majority of our estimated remaining contract value is not funded backlog. The estimates used to compile remaining contract value are based on our experience under contracts, and we believe the estimates are reasonable. However, there can be no assurance that existing contracts will result in earned revenue in any future period or at all.

Business Segments, Foreign Operations, and Major Customers

Additional business segment, foreign operations and major customer information is provided in our Consolidated Financial Statements contained in this Report. In particular, see Note 16, Business Segment, Customer and Geographic Information, in the Notes to Consolidated Financial Statements contained in this Annual Report on Form 10-K.

Revenue by Contract Type

The following information is provided on the amounts of our revenue attributable to cost reimbursable contracts, firm fixed-price contracts (including proprietary software product sales) and T&M contracts during each of the last three fiscal years:

Item 1A. Risk Factors

You should carefully consider the risks and uncertainties described below, together with the information included elsewhere in this Annual Report on Form 10-K and other documents we file with the SEC. The risks and uncertainties described below are those that we have identified as material, but are not the only risks and uncertainties facing us. Our business is also subject to general risks and uncertainties that affect many other companies, such as overall U.S. and non-U.S. economic and industry conditions including a global economic slowdown, geopolitical events, changes in laws or accounting rules, fluctuations in interest and exchange rates, terrorism, international conflicts, major health concerns, natural disasters or other disruptions of expected economic and business conditions. Additional risks and uncertainties not currently known to us or that we currently believe are immaterial also may impair our business operations and liquidity.

We depend on contracts with the federal government for a substantial majority of our revenue, and our business could be seriously harmed if the government significantly decreased or ceased doing business with us.

We derived 94.4 percent of our total revenue in FY2013 and 94.5 percent of our total revenue in FY2012 from federal government contracts, either as a prime contractor or a subcontractor. We derived 74.3 percent of our total revenue in FY2013 and 78.0 percent of our total revenue in FY2012 from contracts with agencies of the DoD. We expect that federal government contracts will continue to be the primary source of our revenue for the foreseeable future. If we were suspended or debarred from contracting with the federal government generally, the General Services Administration, or any significant agency in the intelligence community or the DoD, or if our reputation or relationship with government agencies were to be impaired, or if the government otherwise ceased doing business with us or significantly decreased the amount of business it does with us, our business, prospects, financial condition and operating results could be materially and adversely affected.

Our business could be adversely affected by delays caused by our competitors protesting major contract awards received by us, resulting in the delay of the initiation of work.

It can take many months to resolve protests by one or more of our competitors of contract awards we receive. The resulting delay in the startup and funding of the work under these contracts may cause our actual results to differ materially and adversely from those anticipated.

Our business could be adversely affected by changes in budgetary priorities of the federal government.

Because we derive a substantial majority of our revenue from contracts with the federal government, we believe that the success and development of our business will continue to depend on our successful participation in federal government contract programs. Changes in federal government budgetary priorities could directly affect our financial performance. A significant decline in government expenditures, a shift of expenditures away from programs that we support or a change in federal government contracting policies could cause federal government agencies to reduce their purchases under contracts, to exercise their right to terminate contracts at any time without penalty or not to exercise options to renew contracts.

Subsequent to the enactment of the Budget Act in August of 2011, the Congress and the Administration were unable to reach agreement on budget reduction measures required by the legislation. On March 1, 2013, as required by the Budget Act, the President ordered sequestration into effect, triggering automatic reductions totaling $85 billion in both defense and domestic discretionary spending through September 30, 2013. On April 10, 2013, also under the terms of the Budget Act, the President signed a sequestration order which directs that total discretionary spending for the government’s fiscal year 2014, starting October 1, 2013, be reduced by $91 billion. The Budget Act required total projected defense spending to decline by $487 billion from the government’s fiscal year 2012 through 2021. These automatic across-the-board budget cuts resulting from sequestration are having and may continue to have significant consequences to our business and industry. In March 2013, Congress passed legislation that was a continuation of a continuing resolution (CR) enacted in September 2012 as well as five full, detailed appropriations bills, which finances all federal government activities through September 30, 2013, the end of its fiscal year. This legislation included adjusted spending levels for programs in order to protect high-priority programs and better manage the sequester.

In years when Congress does not complete its budget process before the end of its fiscal year (September 30), government operations are funded through a CR that temporarily funds federal agencies. Recent CRs have generally provided funding at the levels provided in the previous fiscal year and have not authorized new spending initiatives. When the federal government operates under a CR, delays can occur in the procurement of products and services. Historically, such delays have not had a material effect on our business; however, should funding of the federal government continue to be provided through CRs during its fiscal year beginning on October 1, 2013 and extended through the entire government 2014 fiscal year, and sequestration continues as part of the implementation of the Budget Act, it could have significant consequences to our business and our industry. If Congress cannot complete its budget process or does not pass a CR by the end of September 2013, a shut down of the federal government will result on October 1, 2013. Were a shut down to occur, it could result in our incurring substantial labor or other costs without being reimbursed under our contracts, or the delaying or cancelling of certain programs. This could also have an adverse effect on our business and our industry.

At times, we may continue to work without funding, and use our funds in order to meet our customer’s desired delivery dates for products or services. It is uncertain at this time which of our programs’ funding could be reduced in future years or whether new legislation will be passed by Congress in the next fiscal year that could result in additional or alternative funding cuts.

Additionally, our business could be seriously affected if the demand for and priority of funding for combat operations in Afghanistan decreases faster than we have anticipated or if we experience an increase in set-asides for small businesses, which could result in our inability to compete directly for prime contracts.

Our federal government contracts may be terminated by the government at any time and may contain other provisions permitting the government not to continue with contract performance, and if lost contracts are not replaced, our operating results may differ materially and adversely from those anticipated.

We derive substantially all of our revenue from federal government contracts that typically span one or more base years and one or more option years. The option periods typically cover more than half of the contract’s potential duration. Federal government agencies generally have the right not to exercise these option periods. In addition, our contracts typically also contain provisions permitting a government client to terminate the contract for its convenience. A decision not to exercise option periods or to terminate contracts for convenience could result in significant revenue shortfalls from those anticipated.

Federal government contracts contain numerous provisions that are unfavorable to us.

Federal government contracts contain provisions and are subject to laws and regulations that give the government rights and remedies, some of which are not typically found in commercial contracts, including allowing the government to:

14

Table of Contents

If the government terminates a contract for convenience, we may recover only our incurred or committed costs, settlement expenses and profit on work completed prior to the termination. If the government terminates a contract for default, we may be unable to recover even those amounts, and instead may be liable for excess costs incurred by the government in procuring undelivered items and services from another source. Depending on the value of a contract, such termination could cause our actual results to differ materially and adversely from those anticipated. Certain contracts also contain organizational conflict of interest (OCI) clauses that limit our ability to compete for or perform certain other contracts. OCIs arise any time we engage in activities that (i) make us unable or potentially unable to render impartial assistance or advice to the government; (ii) impair or might impair our objectivity in performing contract work; or (iii) provide us with an unfair competitive advantage. For example, when we work on the design of a particular system, we may be precluded from competing for the contract to develop and install that system. Depending upon the value of the matters affected, an OCI issue that precludes our participation in or performance of a program or contract could cause our actual results to differ materially and adversely from those anticipated.

As is common with government contractors, we have experienced and continue to experience occasional performance issues under certain of our contracts. Depending upon the value of the matters affected, a performance problem that impacts our performance of a program or contract could cause our actual results to differ materially and adversely from those anticipated.

If we fail to establish and maintain important relationships with government entities and agencies, our ability to successfully bid for new business may be adversely affected.

To facilitate our ability to prepare bids for new business, we rely in part on establishing and maintaining relationships with officials of various government entities and agencies. These relationships enable us to provide informal input and advice to government entities and agencies prior to the development of a formal bid. We may be unable to successfully maintain our relationships with government entities and agencies, and any failure to do so may adversely affect our ability to bid successfully for new business and could cause our actual results to differ materially and adversely from those anticipated.

We derive significant revenue from contracts and task orders awarded through a competitive bidding process. If we are unable to consistently win new awards over any extended period, our business and prospects will be adversely affected.

Substantially all of our contracts and task orders with the federal government are awarded through a competitive bidding process. We expect that much of the business that we will seek in the foreseeable future will continue to be awarded through competitive bidding. Budgetary pressures and changes in the procurement process have caused many government clients to increasingly purchase goods and services through IDIQ contracts, GSA schedule contracts and other government-wide acquisition contracts. These contracts, some of which are awarded to multiple contractors, have increased competition and pricing pressure, requiring that we make sustained post-award efforts to realize revenue under each such contract. In addition, in consideration of the practice of agencies awarding work under such contracts that is arguably outside the intended scope of the contracts, both the GSA and the DoD have initiated programs aimed to ensure that all work fits properly within the scope of the contract under which it is awarded. The net effect of such programs may reduce the number of bidding opportunities available to us. Moreover, even if we are highly qualified to work on a particular new contract, we might not be awarded business because of the federal government’s policy and practice of maintaining a diverse contracting base.

15

Table of Contents

This competitive bidding process presents a number of risks, including the following:

If we are unable to win particular contracts, we may be prevented from providing to clients services that are purchased under those contracts for a number of years. If we are unable to consistently win new contract awards over any extended period, our business and prospects will be adversely affected and that could cause our actual results to differ materially and adversely from those anticipated. In addition, upon the expiration of a contract, if the client requires further services of the type provided by the contract, there is frequently a competitive rebidding process. There can be no assurance that we will win any particular bid, or that we will be able to replace business lost upon expiration or completion of a contract, and the termination or non-renewal of any of our significant contracts could cause our actual results to differ materially and adversely from those anticipated.

Our business may suffer if we or our employees are unable to obtain the security clearances or other qualifications we and they need to perform services for our clients.

Many of our federal government contracts require us to have security clearances and employ personnel with specified levels of education, work experience and security clearances. Depending on the level of clearance, security clearances can be difficult and time-consuming to obtain. If we or our employees lose or are unable to obtain necessary security clearances, we may not be able to win new business and our existing clients could terminate their contracts with us or decide not to renew them. To the extent we cannot obtain or maintain the required security clearances for our employees working on a particular contract, we may not derive the revenue anticipated from the contract, which could cause our results to differ materially and adversely from those anticipated.

We must comply with a variety of laws and regulations, and our failure to comply could cause our actual results to differ materially from those anticipated.

We must observe laws and regulations relating to the formation, administration and performance of federal government contracts which affect how we do business with our clients and may impose added costs on our business. For example, the Federal Acquisition Regulation and the industrial security regulations of the DoD and related laws include provisions that:

Our failure to comply with these or other laws and regulations could result in contract termination, loss of security clearances, suspension or debarment from contracting with the federal government, civil fines and damages and criminal prosecution and penalties, any of which could cause our actual results to differ materially and adversely from those anticipated.

The federal government may change its procurement or other practices in a manner adverse to us.

The federal government may change its procurement practices, such as in proposed acquisition reforms, or adopt new contracting rules and regulations, such as cost accounting standards. It could also adopt new contracting methods relating to GSA contracts or other government-wide contracts, adopt new socio-economic requirements, or change the basis upon which it reimburses our compensation and other expenses or otherwise limit such reimbursements. In all such cases, there is uncertainty surrounding the changes and what actual impacts they may have on contractors. These changes could impair our ability to obtain new contracts or win re-competed contracts or adversely affect our future profit margin. Any new contracting methods could be costly or administratively difficult for us to satisfy and, as a result, could cause actual results to differ materially and adversely from those anticipated.

Restrictions on or other changes to the federal government’s use of service contracts may harm our operating results.

We derive a significant amount of revenue from service contracts with the federal government. The government may face restrictions from new legislation, regulations or government union pressures, on the nature and amount of services the government may obtain from private contractors (i.e., insourcing versus outsourcing). Any reduction in the government’s use of private contractors to provide federal services could cause our actual results to differ materially and adversely from those anticipated.

Our contracts and administrative processes and systems are subject to audits and cost adjustments by the federal government, which could reduce our revenue, disrupt our business or otherwise adversely affect our results of operations.

Federal government agencies, including the Defense Contract Audit Agency (DCAA) and the Defense Contract Management Agency (DCMA), routinely audit and investigate government contracts and government contractors’ administrative processes and systems. These agencies review our performance on contracts, pricing practices, cost structure and compliance with applicable laws, regulations and standards. They also evaluate the adequacy of internal controls over our business systems, including our purchasing, accounting, estimating, earned value management, and government property systems. Any costs found to be improperly allocated to a specific contract will not be reimbursed, and any such costs already reimbursed must be refunded and certain penalties may be imposed. Moreover, if any of the administrative processes and systems is found not to comply with requirements, we may be subjected to increased government scrutiny and approval that could delay or otherwise adversely affect our ability to compete for or perform contracts or collect our revenue in a timely manner. Therefore, an unfavorable outcome of an audit by the DCAA or another government agency could cause actual results to differ materially and adversely from those anticipated. If a government investigation uncovers improper or illegal activities, we may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeitures of profits, suspension of payments, fines and suspension or debarment from doing business with the federal government. In addition, we could suffer serious reputational harm if allegations of impropriety were made against us. Each of these results could cause actual results to differ materially and adversely from those anticipated. DCAA audits for costs incurred on work performed after June 30, 2005 have not yet been completed. In addition, DCAA audits for costs incurred by our recent acquisitions for certain periods prior to acquisition have not yet been completed. We do not know the outcome of any existing or future audits and if any future audit adjustments significantly exceed our estimates our profitability could be adversely affected.

Failure to maintain strong relationships with other contractors could result in a decline in our revenue.

We derive substantial revenue from contracts in which we act as a subcontractor or from teaming arrangements in which we and other contractors bid on particular contracts or programs. As a subcontractor or teammate, we often lack control over fulfillment of a contract, and poor performance on the contract could impact our customer relationship, even when we perform as required. We expect to continue to depend on

17

relationships with other contractors for a portion of our revenue in the foreseeable future. Moreover, our revenue and operating results could differ materially and adversely from those anticipated if any prime contractor or teammate chose to offer directly to the client services of the type that we provide or if they team with other companies to provide those services.

We may not receive the full amounts authorized under the contracts included in our backlog, which could reduce our revenue in future periods below the levels anticipated.

Our backlog consists of funded backlog, which is based on amounts actually committed by a client for payment for goods and services, and unfunded backlog, which is based upon management’s estimate of the future potential of our existing contracts and task orders, including options, to generate revenue. Our backlog may not result in actual revenue in any particular period, or at all, which could cause our actual results to differ materially and adversely from those anticipated.

The maximum contract value specified under a government contract or task order awarded to us is not necessarily indicative of the revenue that we will realize under that contract. For example, we derive a substantial portion of our revenue from government contracts in which we are not the sole provider, meaning that the government could turn to other companies to fulfill the contract. We also derive revenue from IDIQ contracts, which do not require the government to purchase a pre-determined amount of goods or services under the contract. Action by the government to obtain support from other contractors or failure of the government to order the quantity of work anticipated could cause our actual results to differ materially and adversely from those anticipated.

Without additional Congressional appropriations, some of the contracts included in our backlog will remain unfunded, which could significantly harm our prospects.

Although many of our federal government contracts require performance over a period of years, Congress often appropriates funds for these contracts for only one year at a time. As a result, our contracts typically are only partially funded at any point during their term, and all or some of the work intended to be performed under the contracts will remain unfunded pending subsequent Congressional appropriations and the obligation of additional funds to the contract by the procuring agency. Nevertheless, we estimate our share of the contract values, including values based on the assumed exercise of options relating to these contracts, in calculating the amount of our backlog. Because we may not receive the full amount we expect under a contract, our estimate of our backlog may be inaccurate and we may generate results that differ materially and adversely from those anticipated.

Employee misconduct, including security breaches, could result in the loss of clients and our suspension or debarment from contracting with the federal government.

We may be unable to prevent our employees from engaging in misconduct, fraud or other improper activities that could adversely affect our business and reputation. Misconduct could include the failure to comply with federal government procurement regulations, regulations regarding the protection of classified information and legislation regarding the pricing of labor and other costs in government contracts. Many of the systems we develop involve managing and protecting information involved in national security and other sensitive government functions. A security breach in one of these systems could prevent us from having access to such critically sensitive systems. Other examples of employee misconduct could include time card fraud and violations of the Anti-Kickback Act. The precautions we take to prevent and detect this activity may not be effective, and we could face unknown risks or losses. As a result of employee misconduct, we could face fines and penalties, loss of security clearance and suspension or debarment from contracting with the federal government, which could cause our actual results to differ materially and adversely from those anticipated.

Our failure to attract and retain qualified employees, including our senior management team, could adversely affect our business.

Our continued success depends to a substantial degree on our ability to recruit and retain the technically skilled personnel we need to serve our clients effectively. Our business involves the development of tailored solutions for our clients, a process that relies heavily upon the expertise and services of our employees. Accordingly, our employees are our most valuable resource. Competition for skilled personnel in the information technology services industry is intense, and technology service companies often experience high attrition among their skilled employees. There is a shortage of people capable of filling these positions and they are likely to remain a limited resource for the foreseeable future. Recruiting and training these personnel require substantial resources. Our failure to attract and retain technical personnel could increase our costs of performing our contractual obligations, reduce our ability to efficiently satisfy our clients’ needs, limit our ability to win new business and cause our actual results to differ materially and adversely from those anticipated.

In addition to attracting and retaining qualified technical personnel, we believe that our success will depend on the continued employment of our senior management team and its ability to generate new business and execute projects successfully. Our senior management team is very important to our business because personal reputations and individual business relationships are a critical element of obtaining and maintaining client engagements in our industry, particularly with agencies performing classified operations. The loss of any of our senior executives could cause us to lose client relationships or new business opportunities, which could cause actual results to differ materially and adversely from those anticipated.

Our markets are highly competitive, and many of the companies we compete against have substantially greater resources.

The markets in which we operate include a large number of participants and are highly competitive. Many of our competitors may compete more effectively than we can because they are larger, better financed and better known companies than we are. In order to stay competitive in our industry, we must also keep pace with changing technologies and client preferences. If we are unable to differentiate our services from those of our competitors, our revenue may decline. In addition, our competitors have established relationships among themselves or with third parties to increase their ability to address client needs. As a result, new competitors or alliances among competitors may emerge and compete more effectively than we can. There is also a significant industry trend towards consolidation, which may result in the emergence of companies which are better able to compete against us. The results of these competitive pressures could cause our actual results to differ materially and adversely from those anticipated.

Our quarterly revenue and operating results could be volatile due to the unpredictability of the federal government’s budgeting process and policy priorities.

Our quarterly revenue and operating results may fluctuate significantly and unpredictably in the future. In particular, if the federal government does not adopt, or delays adoption of, a budget for each fiscal year beginning on October 1, or fails to pass a continuing resolution, federal agencies may be forced to suspend our contracts and delay the award of new and follow-on contracts and orders due to a lack of funding. Further, the rate at which the federal government procures technology may be negatively affected following changes in presidential administrations and senior government officials. Therefore, period-to-period comparisons of our operating results may not be a good indication of our future performance.

Our quarterly operating results may not meet the expectations of securities analysts or investors, which in turn may have an adverse effect on the market price of our common stock.

We may lose money or generate less than anticipated profits if we do not accurately estimate the cost of an engagement which is conducted on a fixed-price basis.

We perform a portion of our engagements on a variety of fixed-price contract vehicles. We derived 28.1 percent of our total revenue in FY2013 and 28.0 percent of our total revenue in FY2012 from fixed-price contracts. Fixed-price contracts require us to price our contracts by predicting our expenditures in advance. In addition, some of our engagements obligate us to provide ongoing maintenance and other supporting or ancillary services on a fixed-price basis or with limitations on our ability to increase prices. Many of our engagements are also on a T&M basis. While these types of contracts are generally subject to less uncertainty than fixed-price contracts, to the extent that our actual labor costs are higher than the contract rates, our actual results could differ materially and adversely from those anticipated.

When making proposals for engagements on a fixed-price basis, we rely on our estimates of costs and timing for completing the projects. These estimates reflect our best judgment regarding our capability to complete the task efficiently. Any increased or unexpected costs or unanticipated delays in connection with the performance of fixed-price contracts, including delays caused by factors outside our control, could make these contracts less profitable or unprofitable. From time to time, unexpected costs and unanticipated delays have caused us to incur losses on fixed-price contracts, primarily in connection with state government clients. On rare occasions, these losses have been significant. In the event that we encounter such problems in the future, our actual results could differ materially and adversely from those anticipated.

Our earnings and margins may vary based on the mix of our contracts and programs.

At June 30, 2013, our backlog included cost reimbursable, T&M and fixed-price contracts. Cost reimbursable and T&M contracts generally have lower profit margins than fixed-price contracts. Our earnings and margins may vary materially and adversely depending on the types of long-term government contracts undertaken, the costs incurred in their performance, the achievement of other performance objectives and the stage of performance at which the right to receive fees, particularly under incentive and award fee contracts, is finally determined.

Systems failures may disrupt our business and have an adverse effect on our results of operations.

Any systems failures, including network, software or hardware failures, whether caused by us, a third party service provider, unauthorized intruders and hackers, computer viruses, natural disasters, power shortages or terrorist attacks, could cause loss of data or interruptions or delays in our business or that of our clients. Like other global companies, we have experienced cyber security threats to our data and systems, our company sensitive information, and our information technology infrastructure, including malware and computer virus attacks, unauthorized access, systems failures and temporary disruptions. Prior cyber attacks directed at us have not had a material adverse impact on our business or our financial results, and we believe that our continuing commitment toward threat detection and mitigation processes and procedures will avoid such impact in the future. Due to the evolving nature of these security threats, however, the impact of any future incident cannot be predicted. In addition, the failure or disruption of our mail, communications or utilities could cause us to interrupt or suspend our operations or otherwise harm our business. Our property and business interruption insurance may be inadequate to compensate us for all losses that may occur as a result of any system or operational failure or disruption and, as a result, our actual results could differ materially and adversely from those anticipated.

The systems and networks that we maintain for our clients, although highly redundant in their design, could also fail. If a system or network we maintain were to fail or experience service interruptions, we might experience loss of revenue or face claims for damages or contract termination. Our errors and omissions liability insurance may be inadequate to compensate us for all the damages that we might incur and, as a result, our actual results could differ materially and adversely from those anticipated.

We may have difficulty identifying and executing acquisitions on favorable terms and therefore may grow at slower than anticipated rates.

One of our key growth strategies has been to selectively pursue acquisitions. Through acquisitions, we have expanded our base of federal government clients, increased the range of solutions we offer to our clients and deepened our penetration of existing markets and clients. We may encounter difficulty identifying and executing suitable acquisitions. To the extent that management is involved in identifying acquisition opportunities or integrating new acquisitions into our business, our management may be diverted from operating our core business. Without acquisitions, we may not grow as rapidly as the market expects, which could cause our actual results to differ materially and adversely from those anticipated. We may encounter other risks in executing our acquisition strategy, including:

Each of these types of risks could cause our actual results to differ materially and adversely from those anticipated.

We may have difficulty integrating the operations of any companies we acquire, which could cause actual results to differ materially and adversely from those anticipated.

The success of our acquisition strategy will depend upon our ability to continue to successfully integrate any businesses we may acquire in the future. The integration of these businesses into our operations may result in unforeseen operating difficulties, absorb significant management attention and require significant financial resources that would otherwise be available for the ongoing development of our business. These integration difficulties include the integration of personnel with disparate business backgrounds, the transition to new information systems, coordination of geographically dispersed organizations, loss of key employees of acquired companies, and reconciliation of different corporate cultures. For these or other reasons, we may be unable to retain key clients of acquired companies. Moreover, any acquired business may fail to generate the revenue or net income we expected or produce the efficiencies or cost-savings we anticipated. Any of these outcomes could cause our actual results to differ materially and adversely from those anticipated.

If our subcontractors fail to perform their contractual obligations, our performance as a prime contractor and our ability to obtain future business could be materially and adversely impacted and our actual results could differ materially and adversely from those anticipated.

Our performance of government contracts may involve the issuance of subcontracts to other companies upon which we rely to perform all or a portion of the work we are obligated to deliver to our clients. A failure by one or more of our subcontractors to satisfactorily deliver on a timely basis the agreed-upon supplies, perform the agreed-upon services, or appropriately manage their vendors may materially and adversely impact our ability to perform our obligations as a prime contractor.

A subcontractor’s performance deficiency could result in the government terminating our contract for default. A default termination could expose us to liability for excess costs of reprocurement by the government and have a material adverse effect on our ability to compete for future contracts and task orders. Depending upon the level of problem experienced, such problems with subcontractors could cause our actual results to differ materially and adversely from those anticipated.

The federal government’s appropriation process and other factors may delay the collection of our receivables, and our business may be adversely affected if we cannot collect our receivables in a timely manner.

We depend on the collection of our receivables to generate cash flow, provide working capital, pay debt and continue our business operations. If the federal government, any of our other clients or any prime contractor for whom we are a subcontractor fails to pay or delays the payment of their outstanding invoices for any reason, our business and financial condition may be materially and adversely affected. The government may fail to pay outstanding invoices for a number of reasons, including lack of appropriated funds or lack of an approved budget. In addition, the DCAA may revoke our direct billing privileges, which would adversely affect our ability to collect our receivables in a timely manner. Contracting officers have the authority to impose contractual withholdings, which can also adversely affect our ability to collect timely. In February 2012, a Defense Federal Acquisition Regulations rule became final, requiring DoD contracting officers to impose contractual withholdings at no less than certain minimum levels if a contracting officer determines that one or more of a contractor’s business systems have one or more significant deficiencies. Some prime contractors for whom we are a subcontractor have significantly less financial resources than we do, which may increase the risk that we may not be paid in full or payment may be delayed. If we experience difficulties collecting receivables, it could cause our actual results to differ materially and adversely from those anticipated.

We have substantial investments in recorded goodwill as a result of prior acquisitions, and changes in future business conditions could cause these investments to become impaired, requiring substantial write-downs that would reduce our operating income.

Goodwill accounts for $1.5 billion of our recorded total assets. We evaluate the recoverability of recorded goodwill amounts annually, or when evidence of potential impairment exists. The annual impairment test is based on several factors requiring judgment. Principally, a decrease in expected reporting unit cash flows or changes in market conditions may indicate potential impairment of recorded goodwill. If there is an impairment, we would be required to write down the recorded amount of goodwill, which would be reflected as a charge against operating income.

Our operations involve several risks and hazards, including potential dangers to our employees and to third parties that are inherent in aspects of our federal business (i.e., counterterrorism training services). If these risks and hazards are not adequately insured, it could adversely affect our operating results.

Our federal business includes the maintenance of global networks and the provision of special operations services (i.e., counterterrorism training) that require us to dispatch employees to various countries around the world. These countries may be experiencing political upheaval or unrest, and in some cases war or terrorism. It is possible that certain of our employees or executives will suffer injury or bodily harm, or be killed or kidnapped in the course of these deployments. We could also encounter unexpected costs for reasons beyond our control in connection with the repatriation of our employees or executives. Any of these types of accidents or other incidents could involve significant potential claims of employees, executives and/or third parties who are injured or killed or who may have wrongful death or similar claims against us.

We maintain insurance policies that mitigate against risk and potential liabilities related to our operations. This insurance is maintained in amounts that we believe are reasonable. However, our insurance coverage may not be adequate to cover those claims or liabilities, and we may be forced to bear significant costs from an accident or incident. Substantial claims in excess of our related insurance coverage could cause our actual results to differ materially and adversely from those anticipated.

Our failure to adequately protect our confidential information and proprietary rights may harm our competitive position.

Our success depends, in part, upon our ability to protect our proprietary information and other intellectual property. Although our employees are subject to confidentiality obligations, this protection may be inadequate to deter misappropriation of our confidential information. In addition, we may be unable to detect unauthorized use of our intellectual property in order to take appropriate steps to enforce our rights. If we are unable to prevent third parties from infringing or misappropriating our copyrights, trademarks or other proprietary information, our competitive position could be harmed and our actual results could differ materially and adversely from those anticipated.

We face additional risks which could harm our business because we have international operations.

We conduct the majority of our international operations in the United Kingdom and the Netherlands. Our international operations comprised 3.7 percent of our revenue in FY2013 and 3.0 percent of our revenue in FY2012. Our international operations are subject to risks associated with operating in a foreign country. These risks include fluctuations in the value of the British pound and the Euro, longer payment cycles, changes in foreign tax laws and regulations and unexpected legislative, regulatory, economic or political changes.

Approximately 70.0 percent of the revenue generated by our international operations are also subject to risks associated with operating a commercial as opposed to a government contracting business, including the effects of general economic conditions in Europe on the telecommunications, computer software and computer services sectors and the impact of more concentrated and intense competition for the reduced volume of work available in those sectors. We are marketing our services to clients in industries that are new to us and our efforts in that regard may be unsuccessful. Other factors that may adversely affect our international operations are difficulties relating to managing our business internationally, integrating recent acquisitions, multiple tax structures and adverse changes in foreign exchange rates. Any of these factors could cause our actual results to differ materially and adversely from those anticipated.

Our senior secured credit facility (the Credit Facility) imposes certain restrictions on our ability to take certain actions which may have an impact on our business, operating results and financial condition.

The Credit Facility imposes certain operating and financial restrictions on us and requires us to meet certain financial tests. These restrictions may significantly limit or prohibit us from engaging in certain transactions, including the following:

The failure to comply with any of these covenants would cause a default under the Credit Facility. A default, if not waived, could cause our debt to become immediately due and payable. In such situations, we may not be able to repay our debt or borrow sufficient funds to refinance it, and even if new financing is available, it may not contain terms that are acceptable to us.

23

Table of Contents

Despite our outstanding debt, we may incur additional indebtedness.

The Credit Facility consists of a $750.0 million revolving credit facility and a $150.0 million term loan facility. At June 30, 2013, $180.0 million was outstanding under the revolving credit facility and $131.2 million was outstanding under the term loan. In addition, we have $300.0 million outstanding under our convertible senior subordinated notes due May 1, 2014 (the Notes). We are able to incur additional debt in the future by drawing down on the unused portion of the revolving credit facility and have flexibility under the Credit Facility to increase the term loan facility or the revolving credit facility in an aggregate amount as of June 30, 2013 of up to $150.0 million with applicable lender approvals. Subsequent to June 30, 2013, this amount was increased to the greater of $250.0 million or 2.75 times the senior secured leverage ratio. In addition, the terms of the Credit Facility allow us to incur additional indebtedness from other sources so long as we satisfy the covenants in the agreement governing the Credit Facility. If new debt is added to our current debt levels, the risks related to our ability to service that debt could increase.

Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial debt.

Interest payments on the Notes are due each May and November and the outstanding principal amount comes due on May 1, 2014. In order to meet this payment obligation we may have to amend or refinance our Credit Facility which we may not be able to do at the expected time, in the amounts we would like, or at all. In addition, there can be no assurance that we will be able to raise the additional liquidity from alternative sources in a timely fashion or on commercially acceptable terms, or at all. As of June 30, 2013, the Credit Facility was scheduled to expire in November 2016. Subsequent to June 30, 2013, the maturity date was extended to August 2018. Principal payments under the term loan facility are due in quarterly installments. Our business may not generate cash flow from operations sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive.

A change in control or fundamental change may adversely affect us.

The Credit Facility provides that certain change in control events with respect to us will constitute a default. Certain fundamental changes, as defined under the Notes, will constitute a change of control under the Credit Facility, and therefore will constitute a default under such facility. Furthermore, the fundamental change provisions, including the provisions requiring the increase to the conversion rate for conversions under the Notes in connection with certain fundamental changes, may in certain circumstances make more difficult or discourage a takeover of our company and the removal of incumbent management.

The conditional conversion features of the Notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional conversion features of the Notes are triggered, holders of the Notes will be entitled to convert the Notes at any time during specified periods at their option. If one or more holders elect to convert their notes, we would be required to settle any converted principal through the payment of cash, which could adversely affect our liquidity. As of June 30, 2013, we had $569.6 million available under our revolving credit facility, which we could use to satisfy payment obligations arising from conversions of the Notes. However, there can be no assurance that all or any portion of this facility will be available at the time any such conversion obligations arise. Our failure to pay the required cash upon conversion as required under the Notes would constitute an event of default which, if not waived, would result in the immediate acceleration of our payment obligations under all of the Notes. Any such default would also result in an event of default under the Credit Facility. In such a situation, we may not be able to repay our debt or borrow sufficient funds to refinance it, and, even if new financing is available, it may be available on terms less favorable than the terms of our existing debt and, potentially, on terms that are unacceptable to us. A material deterioration in our financial condition or operating results could inhibit our access to additional investment capital and may cause the price of our common stock to decline.

Item 2. Properties

As of June 30, 2013, we leased office space at 116 U.S. locations containing an aggregate of approximately 2.2 million square feet located in 28 states and the District of Columbia. In four countries outside the U.S., we leased office space at 11 locations containing an aggregate of approximately 60,000 square feet. Our leases expire primarily within the next five years, with the exception of eight leases in the Washington, DC metropolitan area and five leases outside of the metro area, which will expire within the next five to 11 years. We anticipate that most of these leases will be renewed or replaced by other leases. All of our offices are in reasonably modern and well-maintained buildings. The facilities are substantially utilized and adequate for present operations.

We maintain our corporate headquarters in approximately 117,000 square feet of space at 1100 North Glebe Road, Arlington, Virginia. See Note 14, Leases, in the Notes to Consolidated Financial Statements contained in this Annual Report on Form 10-K for additional information regarding our lease commitments.

Item 3. Legal Proceedings

Al Shimari, et al. v. L-3 Services, Inc. et al.

On June 30, 2008, Plaintiff Al Shimari filed a twenty-count complaint in the United States District Court for the Southern District of Ohio. Plaintiff Al Shimari is an Iraqi who claimed that he suffered significant physical injury and emotional distress while held at Abu Ghraib prison in Iraq. The lawsuit named CACI International Inc, CACI Premier Technology, Inc. and former CACI employee Timothy Dugan as Defendants, along with L-3 Services, Inc. The complaint alleged that the Defendants conspired with U.S. military personnel to engage in illegal treatment of Iraqi detainees. The complaint did not allege any interaction between Plaintiff Al Shimari and any CACI employee. Plaintiff Al Shimari sought, inter alia, compensatory damages, punitive damages, and attorney’s fees. On August 8, 2008, the court granted CACI’s motion to transfer the action to the United States District Court for the Eastern District of Virginia. Thereafter, an amended complaint was filed adding three plaintiffs. On September 12, 2008, Mr. Dugan was dismissed from the case without prejudice. On October 2, 2008, CACI filed a motion to dismiss the case. CACI also moved to stay discovery pending further proceedings. The court granted CACI’s motion to stay discovery. On March 18, 2009, the court granted in part and denied in part CACI’s motion to dismiss. On March 23, 2009, CACI filed a notice of appeal with respect to the March 18, 2009 decision. Plaintiffs filed a motion to strike CACI’s notice of appeal and a motion to lift the stay on discovery. The United States District Court for the Eastern District of Virginia denied both motions. On April 27, 2009, Plaintiffs filed a motion to dismiss the appeal in the United States Court of Appeals for the Fourth Circuit. The United States Court of Appeals for the Fourth Circuit deferred any ruling on Plaintiffs’ motion and issued a briefing schedule. Plaintiffs filed a notice of cross-appeal, which CACI moved to dismiss. The Court of Appeals dismissed the Plaintiffs’ cross-appeal. On October 26, 2010, the United States Court of Appeals for the Fourth Circuit heard oral argument in the appeal and took the matter under advisement. On September 21, 2011, the United States Court of Appeals for the Fourth Circuit reversed the decision of the United States District Court for the Eastern District of Virginia and remanded the action with instructions to dismiss the action. On October 5, 2011, Plaintiffs filed a petition for a rehearing en banc, which the Court of Appeals granted. The Court of Appeals also invited the United States to participate in the en banc rehearing of the appeal as amicus curiae. The United States participated in that capacity in the en banc rehearing. On January 27, 2012, the Court of Appeals, sitting en banc, heard oral argument. On May 11, 2012, the Court of Appeals, in an 11-3 decision, held that it lacked jurisdiction over the appeal and dismissed the appeal. The action returned to the district court for further proceedings.

On October 12, 2012, the district court conducted a status conference at which the court asked the parties to prepare and submit a plan for discovery in the action. The parties subsequently filed a joint discovery plan, which

25

Table of Contents

the court approved. The Court also lifted the stay of discovery, and reinstated the claims arising under the Alien Tort Statute (ATS) that the Court had previously dismissed. On December 26, 2012, Plaintiffs filed a Second Amended Complaint. Defendants moved to dismiss several counts of the Second Amended Complaint. On March 8, 2013, the Court dismissed the conspiracy claims in the Second Amended Complaint, and dismissed CACI International Inc from the action. Subsequently, the Court allowed Plaintiffs to file a Third Amended Complaint for the purpose of repleading the conspiracy claims. On March 28, 2013, Plaintiffs filed a Third Amended Complaint, and on April 15, 2013, Defendant CACI Premier Technology, Inc. moved to dismiss the conspiracy claims in the Third Amended Complaint.

On March 19, 2013, the Court granted a motion for reconsideration filed by Defendants with respect to the statute of limitations applicable to the common law tort claims of three of the four Plaintiffs, and dismissed those claims. Defendant CACI Premier Technology, Inc. also filed a motion for sanctions with respect to the failure of three of the four Plaintiffs to appear for depositions and medical examinations as ordered by the court. On April 12, 2013, the Court denied that motion but entered an order requiring the three Plaintiffs to appear for depositions and medical examinations no later than April 26, 2013 and stating that if the three Plaintiffs did not comply with the order their claims were subject to dismissal. Plaintiffs did not appear for depositions in the United States as of April 26, 2013. Defendant CACI Premier Technology, Inc. then renewed its motion for sanctions, seeking dismissal, for the three Plaintiffs’ violation of the Court order to appear for depositions and medical examinations. Defendant CACI Premier Technology, Inc. also filed a motion to dismiss the ATS claims of all four Plaintiffs for lack of jurisdiction in light of the U.S. Supreme Court’s April 17, 2013 decision in Kiobel v. Royal Dutch Petroleum, and a motion to dismiss the common law claims of the single Plaintiff with those claims on various grounds.

On June 26, 2013, the Court issued a Memorandum Opinion and Order granting Defendant CACI Premier Technology, Inc.’s motions with respect to Plaintiffs’ ATS claims and Plaintiffs’ common law claims, and dismissing the Third Amended Complaint without prejudice. The Court also denied all other pending motions, including Defendant CACI Premier Technology, Inc.’s motions for sanctions and to dismiss the conspiracy claims, as moot.

On July 24, 2013, Plaintiffs filed a Notice of Appeal of the district court’s June 26 decision.

We are vigorously defending the above-described legal proceeding, and, based on our present knowledge of the facts, believe the lawsuit is completely without merit.

Item 5. Market for the Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Our common stock is listed on the New York Stock Exchange under the ticker symbol “CACI”.

The ranges of high and low sales prices of our common stock quoted on the New York Stock Exchange for each quarter during the fiscal years ended June 30, 2013 and 2012 were as follows:

We have never paid a cash dividend. Our present policy is to retain earnings to provide funds for the operation and expansion of our business. We do not intend to pay any cash dividends at this time. The Board of Directors will determine whether to pay dividends in the future based on conditions then existing, including our earnings, financial condition and capital requirements, as well as economic and other conditions as the board may deem relevant.

As of August 20, 2013, the number of stockholders of record of our common stock was approximately 306. The number of stockholders of record is not representative of the number of beneficial stockholders due to the fact that many shares are held by depositories, brokers, or nominees.

Overview

We are a leading provider of information solutions and services to the U.S. government. We derived 94.4 percent of our revenue during the year ended June 30, 2013 from contracts with U.S. government agencies, including 74.3 percent from DoD customers and 20.1 percent from U.S. federal civilian agency customers including the Department of Homeland Security. We also provide services to state and local governments, commercial customers and agencies of foreign governments.

Budgetary pressures and sequestration have created a challenging environment for us and other companies in our industry. For further information on the trends currently impacting us, please see Item 1, Business—Industry Trends.

For the year ended June 30, 2013, 87.9 percent of our revenue was from contracts where we were the lead, or “prime,” contractor. Our contract base has approximately 610 active contracts and 1,780 active task orders. We have a diverse mix of contract types, with 48.4 percent, 28.1 percent, and 23.5 percent of our revenue for the year ended June 30, 2013, derived from cost-reimbursable, fixed-price and T&M contracts, respectively. We generally do not pursue fixed-price software development contracts that may create financial risk.

Critical Accounting Policies and Estimates

The preparation of our consolidated financial statements in conformity with accounting principles generally accepted in the U.S. requires us to make estimates and judgments that affect the amounts reported in those financial statements and accompanying notes. We consider the accounting policies and estimates addressed below to be the most important to our financial position and results of operations, either because of the significance of the financial statement item or because they require the exercise of significant judgment and/or use of significant estimates. Although we believe that the estimates we use are reasonable, due to the inherent uncertainty involved in making those estimates, actual results reported in future periods could differ from those estimates.

Revenue Recognition/Contract Accounting

We generate almost all of our revenue from three different types of contractual arrangements: cost-plus-fee contracts, T&M contracts, and fixed-price contracts. Revenue on cost-plus-fee contracts is recognized to the extent of allowable costs incurred plus an estimate of the applicable fees earned. We consider fixed fees under cost-plus-fee contracts to be earned in proportion to the allowable costs incurred in performance of the contract. For cost-plus-fee contracts that include performance based fee incentives, and that are subject to the provisions of Accounting Standards Codification (ASC) Section 605-35, Revenue Recognition—Construction-Type and Production-Type Contracts (ASC 605-35), we recognize the relevant portion of the expected fee to be awarded by the customer at the time such fee can be reasonably estimated, based on factors such as our prior award experience and communications with the customer regarding performance. For such cost-plus-fee contracts subject to the provisions of ASC 605-10-S99, Revenue Recognition—SEC Materials (ASC 605-10-S99), we recognize the relevant portion of the fee upon customer approval. Revenue on T&M contracts is recognized to the extent of billable rates times hours delivered for services provided, to the extent of material cost for products delivered to customers, and to the extent of expenses incurred on behalf of the customers. Shipping and handling fees charged to the customers are recognized as revenue at the time products are delivered to the customers.

We have four basic categories of fixed price contracts: fixed unit price, fixed price-level of effort, fixed price-completion, and fixed price-license. Revenue on fixed unit price contracts, where specified units of output under service arrangements are delivered, is recognized as units are delivered based on the specified price per unit. Revenue on fixed unit price maintenance contracts is recognized ratably over the length of the service period. Revenue for fixed price-level of effort contracts is recognized based upon the number of units of labor actually delivered multiplied by the agreed rate for each unit of labor.

30

Table of Contents

A significant portion of our fixed price-completion contracts involve the design and development of complex client systems. For these contracts that are within the scope of ASC 605-35, revenue is recognized on the percentage of completion method using costs incurred in relation to total estimated costs. For fixed price-completion contracts that are not within the scope of ASC 605-35, revenue is generally recognized ratably over the service period.

Contract accounting requires judgment relative to assessing risks, estimating contract revenue and costs, and making assumptions for schedule and technical issues. Due to the size and nature of many of our contracts, the estimation of total revenue and cost at completion is complicated and subject to many variables. Contract costs include material, labor, subcontracting costs, and other direct costs, as well as an allocation of allowable indirect costs. Assumptions have to be made regarding the length of time to complete the contract because costs also include expected increases in wages and prices for materials. For contract change orders, claims or similar items, we apply judgment in estimating the amounts and assessing the potential for realization. These amounts are only included in contract value when they can be reliably estimated and realization is considered probable. Incentives or penalties related to performance on contracts are considered in estimating sales and profit rates, and are recorded when there is sufficient information for us to assess anticipated performance. Estimates of award fees for certain contracts may also be a factor in estimating revenue and profit rates based on actual and anticipated awards.

Long-term development and production contracts make up a large portion of our business, and therefore the amounts we record in our financial statements using contract accounting methods are material. For our federal contracts, we follow U.S. government procurement and accounting standards in assessing the allowability and the allocability of costs to contracts. Due to the significance of the judgments and estimation processes, it is likely that materially different amounts could be recorded if we used different assumptions or if the underlying circumstances were to change. We closely monitor compliance with, and the consistent application of, our critical accounting policies related to contract accounting. Business operations personnel conduct periodic contract status and performance reviews. When adjustments in estimated contract revenue or costs are required, any significant changes from prior estimates are included in earnings in the current period. Also, regular and recurring evaluations of contract cost, scheduling and technical matters are performed by management personnel who are independent from the business operations personnel performing work under the contract. Costs incurred and allocated to contracts with the U.S. government are scrutinized for compliance with regulatory standards by our personnel, and are subject to audit by the DCAA.

From time to time, we may proceed with work based on client direction prior to the completion and signing of formal contract documents. We have a formal review process for approving any such work. Revenue associated with such work is recognized only when it can be reliably estimated and realization is probable. We base our estimates on previous experiences with the client, communications with the client regarding funding status, and our knowledge of available funding for the contract or program.

Costs of Revenue

Costs of revenue include all direct contract costs as well as indirect overhead costs and selling, general and administrative expenses that are allowable and allocable to contracts under federal procurement standards. Costs of revenue also include costs and expenses that are unallowable under applicable procurement standards, and thus are not allocable to contracts for billing purposes. Such costs and expenses do not directly generate revenue, but are necessary for business operations.

Accounting for Business Combinations, Goodwill and Acquired Intangible Assets

The purchase price of an acquired business is allocated to the tangible assets and separately identifiable intangible assets acquired less liabilities assumed based upon their respective fair values, with the excess recorded as goodwill.

31

Table of Contents

We evaluate goodwill at least annually for impairment, or whenever events or circumstances indicate that the carrying value may not be recoverable. The evaluation includes comparing the fair value of the relevant reporting unit to the carrying value, including goodwill, of such unit. If the fair value exceeds the carrying value, no impairment loss is recognized. However, if the carrying value of the reporting unit exceeds its fair value, the goodwill of the reporting unit may be impaired. Impairment is measured by comparing the derived fair value of the goodwill to its carrying value. Separately identifiable intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment if impairment indicators are present.

We have two reporting units—domestic operations and international operations. Our reporting units are the same as our operating segments. Approximately 95 percent of our goodwill is attributable to our domestic operations. We estimate the fair value of our reporting units using both an income approach and a market approach. The valuation process considers our estimates of the future operating performance of each reporting unit. Companies in similar industries are researched and analyzed and we consider the domestic and international economic and financial market conditions, both in general and specific to the industry in which we operate, prevailing as of the valuation date. The income approach utilizes discounted cash flows.

During the quarter ended June 30, 2013, we voluntarily changed the date of our annual goodwill impairment testing from the last day of the fourth quarter to the first day of the fourth quarter. This change is preferable as it provides us with additional time to complete our annual goodwill impairment testing in advance of our year-end reporting and results in better alignment with our strategic planning and forecasting process. In accordance with U.S. generally accepted accounting principles, we will continue to perform interim impairment testing should circumstances requiring it arise. This change does not result in the delay, acceleration, or avoidance of an impairment charge. This change has no indirect effects and is not applied retrospectively as it is impracticable to do so because retrospective application would require application of significant estimates and assumptions with the use of hindsight. Accordingly, the change will be applied prospectively. We completed our annual goodwill assessment as of April 1, 2013 and no impairment charge was necessary as a result of this assessment.

Stock-Based Compensation

Under our 2006 Stock Incentive Plan, we issue equity instruments on an annual basis to our directors and key employees. These instruments may take the form of, among others, shares of restricted stock, restricted stock units (RSUs), stock settled stock appreciation rights (SSARs) and non-qualified stock options (NQSOs). We also issue equity instruments in the form of RSUs under our Management Stock Purchase Plan and Director Stock Purchase Plan.

We account for share-based payments to employees, including grants of employee stock awards and purchases under employee stock purchase plans, in accordance with ASC 718, Compensation—Stock Compensation, which requires that share-based payments (to the extent they are compensatory) be recognized in our consolidated statements of operations based on their fair values. We determine the fair value of our NQSOs and SSARs at the date of grant using option-pricing models such as the Black-Scholes or binomial lattice model. We determine the fair value of our market-based and performance-based RSUs at the date of grant using generally accepted valuation techniques and the closing market price of our stock. Stock-based compensation cost is recognized as expense over the requisite service period.

Under the terms of the various equity instrument agreements, vesting of awards may accelerate to varying degrees based on the age of the grantee and the type of equity instrument. Depending on the instrument, vesting may accelerate upon retirement at either age 62 or 65 with the amount of acceleration based on the length of service provided.

Results of Operations

The following table sets forth the relative percentages that certain items of expense and earnings bear to revenue.

Consolidated Statements of Operations

Years ended June 30,

Revenue

For FY2013, our total revenue decreased by $92.5 million, or 2.5 percent. Our revenue from existing operations decreased 5.7 percent, or $216.8 million, primarily related to a decrease in revenue from DoD. This decrease was partially offset by $124.3 million of revenue associated with acquired businesses. Revenue generated from the date a business is acquired though the first anniversary of that date is considered acquired revenue.

During FY2012, total revenue increased by $196.7 million, or 5.5 percent. Approximately 2.4 percent, or $87.0 million, of revenue growth was organic and resulted primarily from increases in services and solutions provided to our DoD, intelligence and federal civilian agency customers. The remaining 3.1 percent increase, or $109.7 million, was generated by acquisitions completed in FY2012 and FY2011.

Our acquired revenue for FY2013 and FY2012 is as follows (in millions):

Table of Contents

The following table summarizes revenue earned by each of the customer groups for the three most recent fiscal years:

Revenue from DoD customers decreased 7.1 percent, or $209.8 million, to $2.7 billion for FY2013 as compared to FY2012. This decrease was attributable primarily to lower other direct costs (ODCs) as a result of both the draw down in Afghanistan and sequestration-related reductions. DoD revenue includes services provided to the U.S. Army, our largest customer, where our services focus on supporting readiness, tactical military intelligence, and communications systems. DoD revenue also includes work with the U.S. Navy, and other DoD agencies.

Revenue from DoD customers increased 3.0 percent, or $86.2 million, to $2.9 billion for FY2012 as compared to FY2011. $48.0 million of the increase was attributable to acquired DoD revenue and the remaining $38.2 million of the increase was attributable to revenue from existing operations.

Revenue from federal civilian agencies increased 19.4 percent, or $120.2 million, to $741.1 million during FY2013 as compared to FY2012. Of the federal civilian agency revenue growth, $23.6 million was attributable to existing operations and $96.6 million was attributable to acquisitions.

Revenue from federal civilian agencies increased 15.5 percent, or $83.2 million, to $620.9 million during FY2012 as compared to FY2011. Of the federal civilian agency revenue growth, $40.1 million was attributable to acquisitions.

Commercial and other revenue decreased 1.9 percent, or $3.7 million, to $190.1 million in FY2013 as compared to FY2012. During FY2012, we had a commercial product sale that generated $12.0 million in revenue. Commercial revenue is derived from both international and domestic operations. In FY2013, international operations accounted for 70.8 percent, or $134.5 million, of the total commercial revenue, while domestic operations accounted for 29.2 percent, or $55.6 million.

Commercial and other revenue increased 16.1 percent, or $26.9 million, to $193.8 million in FY2012 as compared to FY2011. This revenue growth came from both acquisitions and the $12.0 million product sale referenced above. In FY2012, international operations accounted for 59.4 percent, or $115.1 million, of the total commercial revenue, while domestic operations accounted for 40.6 percent, or $78.7 million.

Revenue from state and local governments increased by 5.8 percent, or $0.9 million during FY2013, as compared to FY2012. In FY2012 as compared to FY2011, revenue from state and local governments increased by 3.0 percent, or $0.4 million. Revenue from state and local governments represented less than one percent of our total revenue in each of FY2013, FY2012, and FY2011.

Income from Operations

Income from operations decreased 9.7 percent or $29.0 million, in FY2013 as compared to FY2012. Our operating margin was 7.4 percent, down from 7.9 percent during the same period a year ago. Operating margin during FY2012 was favorably impacted by greater than expected profitability on a large fixed price contract.

34

Table of Contents

Income from operations increased 19.3 percent, or $48.4 million, in FY2012 as compared to FY2011. Our operating margin in FY2012 of 7.9 percent increased from 7.0 percent in FY2011. The increase in margin rate related primarily to strong direct labor growth and the aforementioned fixed price contract.

During the fiscal years ended June 30, 2013, 2012, and 2011, as a percentage of revenue, total direct costs were 68.8 percent, 68.9 percent, and 70.7 percent, respectively. Direct costs include direct labor and ODCs, which include, among other costs, subcontracted labor and materials along with equipment purchases and travel expenses. ODCs, which are common in our industry, typically are incurred in response to specific client tasks and may vary from period to period.

The single largest component of direct costs, direct labor, was $1.0 billion, $977.7 million and $888.0 million in FY2013, FY2012, and FY2011, respectively. ODCs were $1.5 billion, $1.6 billion, and $1.6 billion in FY2013, FY2012, and FY2011, respectively.

Indirect costs and selling expenses which include fringe benefits (attributable to both direct and indirect labor), marketing and bid and proposal costs, indirect labor and other discretionary expenses, increased $1.7 million or 0.2 percent in FY2013 as compared to FY2012. As a percentage of revenue indirect costs and selling expenses were 22.3 percent, 21.7 percent and 20.7 percent for FY2013, FY2012 and FY2011, respectively. In addition to an increase in fringe benefit expense associated with our increase in direct labor, indirect costs and selling expenses were increased by $7.1 million of severance expense and $2.3 million of lease-related expenses associated with cost reduction activities. These actions resulted from a strategic review of our business in response to sequestration and other government actions which negatively impacted our operations. Profit bonus expense recorded in FY2013, which in large part is based on the Company’s performance, was $34.3 million lower than profit bonus expense recorded in FY2012.

Indirect expense in FY2012 and FY2011 reflected a reduction of expense associated with the reduction in the fair value of acquisition-related contingent consideration liabilities related to acquisitions completed in FY2010. The reduction recorded was $0.4 million in FY2012 and $9.6 million in FY2011.

A component of indirect costs and selling expenses is stock compensation. Total stock compensation expense was $8.8 million, $15.5 million, and $17.9 million for the fiscal years ended June 30, 2013, 2012, and 2011, respectively. In September 2012, we made our annual grant of Performance-based Restricted Stock Units (PRSUs) to our key employees and began recording the associated stock compensation expense. The vesting of these PRSUs was based in part on the achievement of a specified net after tax profit for FY2013, which was not met. Stock compensation expense recorded before we determined it was probable that the performance metric would not be met was reversed and, accordingly, stock compensation expense in FY2013 does not include any expense for this year’s annual grant. The decrease in stock compensation expense from FY2011 to FY2012 was due primarily to a higher level of forfeitures in FY2012 and a decrease in stock compensation expense associated with the issuance of performance-based RSUs in FY2009 and FY2010.

Depreciation and amortization expense decreased $1.9 million, or 3.4 percent, in FY2013 as compared to FY2012. The decrease was attributable to decreased amortization of intangible assets offset by increases in depreciation and leasehold improvement amortization expense. In FY2012 as compared to FY2011, depreciation and amortization expense decreased $0.1 million, or 0.2 percent.

Net interest expense and other increased $1.7 million, or 7.1 percent, in FY2013 as compared to FY2012. This increase was primarily attributable to an increase in interest expense related to higher outstanding debt. Net interest expense and other increased $1.0 million, or 4.1 percent, in FY2012 as compared to FY2011 primarily as a result of an increase in interest expense related to higher outstanding debt which was partially offset by a decrease in amortization of deferred financing costs. Interest expense and other includes a reduction for our share of the net income of AC First, LLC, a joint venture between us and AECOM Government Services, Inc. of $2.6 million in FY2013 and $1.7 million in FY2012.

Table of Contents

The effective income tax rates in FY2013, FY2012, and FY2011, were 37.8 percent, 39.1 percent, and 36.6 percent, respectively. The tax rate in each year benefitted from tax benefits related to deductions claimed for income from qualified domestic production activities and non-taxable gains on assets invested in corporate-owned life insurance (COLI) policies.

Quarterly Financial Information

Quarterly financial data for the two most recent fiscal years is provided in Note 25, Quarterly Financial Data, in the Notes to Consolidated Financial Statements contained in this Annual Report on Form 10-K.

Effects of Inflation

During FY2013, 48.4 percent of our business was conducted under cost-reimbursable contracts which automatically adjust revenue to cover costs that are affected by inflation. 23.5 percent of our revenue was earned under T&M contracts, where labor rates for many of the services provided are often fixed for several years. Under certain T&M contracts containing IDIQ procurement arrangements, we do adjust labor rates annually as permitted. The remaining portion of our business is fixed-price and may span multiple years. We generally have been able to price our T&M and fixed-price contracts in a manner that accommodates the rates of inflation experienced in recent years.

Liquidity and Capital Resources

Historically, our positive cash flow from operations and our available credit facilities have provided adequate liquidity and working capital to fund our operational needs. Cash flows from operations totaled $249.3 million, $271.2 million and $231.2 million for the years ended June 30, 2013, 2012 and 2011, respectively.

The Credit Facility is a $900.0 million credit facility, which includes a $750.0 million revolving credit facility (the Revolving Facility), and a $150.0 million term loan (the Term Loan). The Revolving Facility has subfacilities of $50.0 million for same-day swing line borrowings and $25.0 million for stand-by letters of credit. At June 30, 2013, $131.3 million was outstanding under the Term Loan, $180.0 million was outstanding under the Revolving Facility, we had no borrowings on the swing line and a $0.4 million letter of credit was outstanding. As of June 30, 2013, the Credit Facility had an accordion feature that would allow the facility to be expanded by an additional $150.0 million with applicable lender approvals. Subsequent to June 30, 2013, this amount was increased to the greater of $250.0 million or 2.75 times the senior secured leverage ratio.

The Term Loan is a five-year secured facility under which principal payments are due, as of June 30, 2013, in quarterly installments of $1.9 million through September 30, 2015 and $3.8 million thereafter through September 30, 2016, with the balance due in full on November 18, 2016. Subsequent to June 30, 2013, the maturity date was extended to August 2018 and appropriate adjustments to the amortization schedule to reflect this change in maturity date were made.

The interest rates applicable to loans under the Credit Facility are floating interest rates that, at our option, equal a base rate or a Eurodollar rate plus, in each case, an applicable margin based upon our consolidated total leverage ratio.

The Credit Facility requires us to comply with certain financial covenants, including a maximum senior secured leverage ratio, a maximum total leverage ratio and a minimum fixed charge coverage ratio. The Credit Facility also includes customary negative covenants restricting or limiting our ability to guarantee or incur additional indebtedness, grant liens or other security interests to third parties, make loans or investments, transfer assets, declare dividends or redeem or repurchase capital stock or make other distributions, prepay subordinated indebtedness and engage in mergers, acquisitions or other business combinations, in each case except as expressly permitted under the Credit Facility. Since the inception of the Credit Facility, we have been in compliance with all of the financial covenants. A majority of our assets serve as collateral under the Credit Facility.

Effective May 16, 2007, we issued the Notes, which mature on May 1, 2014, in a private placement pursuant to Rule 144A of the Securities Act of 1933. The Notes are subordinate to our senior secured debt, and interest on the Notes is payable on May 1 and November 1 of each year.

Holders may convert their notes at a conversion rate of 18.2989 shares of CACI common stock for each $1,000 of note principal (an initial conversion price of $54.65 per share) under the following circumstances: 1) if the last reported sale price of CACI stock is greater than or equal to 130 percent of the conversion price for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter; 2) during the five consecutive business day period immediately after any ten consecutive trading day period (the note measurement period) in which the average of the trading price per $1,000 principal amount of convertible note was equal to or less than 97 percent of the average product of the closing price of a share of our common stock and the conversion rate of each date during the note measurement period; 3) upon the occurrence of certain corporate events, as defined; or 4) during the last three-month period prior to maturity. We are required to satisfy 100 percent of the principal amount of these notes solely in cash, with any amounts above the principal amount to be satisfied in common stock. As of June 30, 2013, none of the conditions permitting conversion of the Notes had been satisfied. As the Notes are due in May 2014, as of June 30, 2013 we have classified the Notes as a current liability.

In the event of a fundamental change, as defined, holders may require us to repurchase the Notes at a price equal to the principal amount plus any accrued interest. Also, if certain fundamental changes occur prior to maturity, we will in certain circumstances increase the conversion rate by a number of additional shares of common stock or, in lieu thereof, we may in certain circumstances elect to adjust the conversion rate and related conversion obligation so that these notes are convertible into shares of the acquiring or surviving company. We are not permitted to redeem the Notes.

In connection with the issuance of the Notes, we purchased in a private transaction at a cost of $84.4 million call options (the Call Options) to purchase approximately 5.5 million shares of our common stock at a price equal to the conversion price of $54.65 per share. The Call Options allow us to receive shares of our common stock from the counterparties equal to the amount of common stock related to the excess conversion value that we would pay the holders of the Notes upon conversion. In addition, we sold warrants (the Warrants) to issue approximately 5.5 million shares of CACI common stock at an exercise price of $68.31 per share. The proceeds from the sale of the Warrants totaled $56.5 million. On a combined basis, the Call Options and the Warrants are intended to reduce the potential dilution of CACI’s common stock in the event that the Notes are converted by effectively increasing the conversion price of these notes from $54.65 to $68.31. The Call Options and the Warrants are separate and legally distinct instruments that bind us and the counterparties and have no binding effect on the holders of the Notes.

Cash and cash equivalents were $64.3 million and $15.7 million as of June 30, 2013 and 2012, respectively. The increase in cash and cash equivalents was primarily attributable to less cash used for acquisitions and repurchases of company stock than in the prior year. Our operating cash flow was $249.3 million for FY2013, compared to $271.2 million for the same period a year ago. Days-sales outstanding were 58 at both June 30, 2013 and 2012.

We used $127.4 million and $204.4 million of cash in investing activities during FY2013 and FY2012, respectively. During the twelve months ended June 30, 2013 we paid $107.0 million for business acquisitions, as compared to $185.9 million during the same period a year ago. Purchases of office and computer related equipment of $15.4 million and $18.3 million in FY2013 and FY2012, respectively, accounted for a majority of the remaining funds used in investing activities. Generally, we have relatively low capital expenditure requirements for our business, and expect these expenditures in the coming years to remain consistent with the levels reported in FY2013.

Cash flows used in financing activities were $73.0 million during FY2013 and $215.5 million during FY2012. During the year ended June 30, 2013, we had net borrowings of $46.9 million under our Credit Facility.

37

Table of Contents

These borrowings along with our available cash balance and our operating cash flow funded our repurchase of 2.3 million shares of company stock for $127.5 million and the acquisitions made during FY2013. During the year ended June 30, 2012 we had net borrowings of $116.3 million under our Credit Facility. Those borrowings along with our available cash balance and our operating cash flow funded our repurchase of 5.8 million shares of company stock for $316.6 million and the acquisitions made during FY2012. During the year ended June 30, 2012 we paid $21.6 million in settlement of contingent consideration for acquisitions completed during the year ended June 30, 2010 as compared to $3.2 million of contingent consideration associated with prior year acquisitions paid during the year ended June 30, 2013. Cash flows from financing activities continued to benefit from proceeds received from the exercise of stock options and purchases of stock under the CACI International Inc Employee Stock Purchase Plan (ESPP). Proceeds from these activities totaled $17.6 million and $11.6 million during FY2013 and FY2012, respectively.

We believe that the combination of internally generated funds, available bank borrowings, and cash and cash equivalents on hand will provide the required liquidity and capital resources necessary to fund on-going operations, customary capital expenditures, debt service obligations, and other working capital requirements over the next twelve months. We expect to pay off the Notes with funds available under the Credit Facility, or with cash on hand, or with cash proceeds from a new debt security. Over the longer term, our ability to generate sufficient cash flows from operations necessary to fulfill the obligations under the Credit Facility will depend on our future financial performance which will be affected by many factors outside of our control, including current worldwide economic conditions.

Off-Balance Sheet Arrangements and Contractual Obligations

We use off-balance sheet arrangements to finance the lease of operating facilities. We have financed the use of all of our current office and warehouse facilities through operating leases. Operating leases are also used to finance the use of computers, servers, phone systems, and to a lesser extent, other fixed assets, such as furnishings, that are obtained in connection with business acquisitions. We generally assume the lease rights and obligations of companies acquired in business combinations and continue financing equipment under operating leases until the end of the lease term following the acquisition date. We generally do not finance capital expenditures with operating leases, but instead finance such purchases with available cash balances. For additional information regarding our operating lease commitments, see Note 14 in the Notes to Consolidated Financial Statements contained in this Annual Report on Form 10-K. The Credit Facility provides for stand-by letters of credit aggregating up to $25.0 million that reduce the funds available under the Revolving Facility when issued. As of June 30, 2013, we had an outstanding letter of credit of $0.4 million. We have no other material off-balance sheet financing arrangements.

The following table summarizes our contractual obligations as of June 30, 2013 that require us to make future cash payments:

Item 7A. Quantitative and Qualitative Disclosure About Market Risk

The interest rates on both the Term Loan and the Revolving Facility are affected by changes in market interest rates. We have the ability to manage these fluctuations in part through interest rate hedging alternatives in the form of interest rate swaps. We have maintained hedging relationships with various counterparties in recent years which allowed us to exchange a portion of our variable rate debt for fixed rate debt. In April 2012, we entered into floating-to-fixed interest rate swap agreements for an aggregate notional amount of $100 million related to a portion of our floating rate indebtedness. The agreements are effective beginning July 1, 2013 and mature July 1, 2017. As of June 30, 2013, all outstanding balances under our Term Loan, and any amounts that may be borrowed under our Revolving Facility, were currently subject to interest rate fluctuations. With every one percent fluctuation in the applicable interest rates, interest expense on our variable rate debt for the year ended June 30, 2013 would have fluctuated by approximately $4.0 million.

Approximately 3.7 percent and 3.0 percent of our total revenue in FY2013 and FY2012, respectively, was derived from our international operations headquartered in the U.K. Our practice in our international operations is to negotiate contracts in the same currency in which the predominant expenses are incurred, thereby mitigating the exposure to foreign currency exchange fluctuations. It is not possible to accomplish this in all cases; thus, there is some risk that profits will be affected by foreign currency exchange fluctuations. As of June 30, 2013, we held a combination of euros and pounds sterling in the U.K. and in the Netherlands equivalent to approximately $15.0 million. This allows us to better utilize our cash resources on behalf of our foreign subsidiaries, thereby mitigating foreign currency conversion risks.

The Consolidated Financial Statements of CACI International Inc and subsidiaries are provided in Part IV in this Annual Report on Form 10-K.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

We had no disagreements with our independent registered public accounting firm on accounting principles, practices or financial statement disclosure during and through the date of the consolidated financial statements included in this report.

Item 9A. Controls and Procedures

We maintain disclosure controls and procedures, as defined in the Exchange Act Ruling 13a-15(e) and 15d-15(e), that are designed to ensure that information required to be disclosed in our periodic filings with the Securities and Exchange Commission (SEC) is recorded, processed, summarized and reported

within the time periods specified in the SEC’s rules and forms. Our disclosure controls and procedures are also designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), as appropriate, to allow timely decisions regarding required disclosure.

The effectiveness of a system of disclosure controls and procedures is subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of future events, the soundness of internal controls, and fraud. Due to such inherent limitations, there can be only reasonable, and not absolute, assurance that any system of disclosure controls and procedures will be successful in detecting or preventing all errors or fraud, or in making all material information known in a timely manner to the appropriate levels of management.

We performed an evaluation of the effectiveness of our disclosure controls and procedures under the supervision of the CEO and CFO, as of June 30, 2013. Based on the evaluation procedures, our management, including the CEO and CFO, concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of June 30, 2013.

The management of CACI International Inc is responsible for establishing and maintaining effective internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f), and for its assessment of the effectiveness of internal control over financial reporting.

We maintain internal controls over financial reporting that are designed to provide reasonable assurance regarding the reliability of financial reporting, and the preparation of financial statements. CACI International Inc’s internal control over financial reporting includes those policies and procedures that 1) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles; 2) ensure the maintenance of records that accurately and fairly reflect our transactions; 3) ensure that our receipts, expenditures and asset dispositions are made in accordance with director and management authorizations; and 4) provide reasonable assurance that our assets are properly safeguarded.

With the participation of our CEO and CFO, we performed an evaluation of the effectiveness of the internal control over financial reporting to comply with the rules on internal control over financial reporting issued pursuant to the Sarbanes-Oxley Act of 2002. In making this evaluation, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework (1992 Framework). Based on the evaluation procedures, our management, including the CEO and CFO, concluded that, as of June 30, 2013, our internal control over financial reporting was effective based on those criteria. In addition, our independent registered public accounting firm evaluated the effectiveness of our internal control over financial reporting. Management’s report on the effectiveness of internal control over financial reporting, and the independent auditors’ report on internal control over financial reporting, are included in Part IV of this report.

Under the supervision and with the participation of our management, an evaluation was also performed of any changes in our internal control procedures over financial reporting that occurred during our last fiscal quarter. Based on this evaluation, management determined there were no changes in our internal control over financial reporting that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
